Dear Shareholders, Business Partners and Employees

“Light is a Fascinating Tool”

Here are the highlights for the fiscal year:

• Gross profit margin improved to 38% for the year. We achieved our 40% margin target in the fourth quarter. A favorable product mix and our ongoing cost reduction program were primary contributors to our margin improvement

• Fully diluted EPS was $1.46, an increase of 64% over last fiscal year

• We maintained a strong balance sheet and have confidence in our long-term prospects. As a result, we initiated our fifth share buyback program. We follow a balanced capital management strategy of investing in our business for growth and returning capital to shareholders, as appropriate

• Annual high-power fiber laser unit sales increased over 70% year-over-year. We continue to target high-power fiber lasers for growth

This is the first time that I am addressing you as the new CEO of the ROFIN group, and I want you to know that it is an honor to lead our great Company. ROFIN has a deep legacy of innovation and performance. We have one of the industry’s broadest product and technology portfolios, along with in-depth applications know-how in industrial laser material processing, and an extensive global footprint and customer reach. Building on these strengths and the many strategic alignments that the Company has implemented over the past few years, my goal is to bring fresh perspectives for future growth, to further enhance ROFIN’s technological and competitive edge, to increase profitability and – above all – to create additional value for our shareholders.

We are proud of the improvements we achieved in financial and operational performance in fiscal year 2015. We realized many of our strategic goals, further strengthening the diversity of our technological product portfolio, enhancing manufacturing capacities and broadening our addressable markets by offering innovative process applications and manufacturing solutions. In addition, we took steps to further improve process and structural efficiency, optimize cost structure and drive margin improvement. These actions both created near-term value for shareholders and better positioned the Group for a future of long-term sustainable success.

Business Performance in Fiscal Year 2015

For this fiscal year, which followed the typical pattern of a seasonally weaker first half followed by a recovery in the second half, we achieved net sales of $519.6 million. Currency translation effects dampened these net sales results, which would have been $49.3 million higher on a constant currency basis, representing organic revenue growth of 7%.

The revenue contribution split of our different businesses was 38% from MACRO applications, 47% from sales for MICRO & MARKING applications and 15% from our COMPONENTS business. On a geographical basis, the market with the highest sales growth was North America, where sales increased by 10% to $112.1 million year-over-year, followed by Asia where the turnover level improved slightly to $174.6 million. Our Asian business represented 34% of total annual revenue, with China as the largest contributor, underscoring the effectiveness of our early engagement and market penetration strategy in this region over the past few years. European revenues decreased by 9% to $232.9 million. Order entry for the period totaled $522.7 million, resulting in a year-end backlog of $144.3 million as of September 30, 2015. The book-to-bill ratio for the full year period was 1.01.

Gross profit for the twelve months reached $196.5 million, which marked a margin improvement from 36% of net sales in the prior year to 38% in fiscal year 2015. In the fourth quarter especially, we saw the positive effects of our cost optimization strategies, helping us to achieve our targeted gross profit margin of 40% for the quarter. This positive development was a result of both a favorable product mix and our ongoing cost reduction measures, primarily in the production of our high-power fiber lasers.

We generated net earnings of $41.3 million for the fiscal year, representing a 64% increase over the prior year, resulting in earnings per

share of $1.46 on a diluted basis. Total capital expenditures amounted to a record $34.0 million, representing an increase of $23.6 million compared to the prior fiscal year. We used this cash to align operations and acquire efficient production capacities to better position us for the future, such as the new production facility for our MICRO headquarters where we will consolidate several locations into one site. Since the majority of essential investments – such as in the vertically integrated manufacture of our high-power fiber lasers – have been completed over the past years, we expect capital expenditures to return to a more customary level in the range of $20 million to $25 million in fiscal year 2016.

During fiscal year 2015, we generated cash from operations of $68.6 million, an increase of 93% over $35.5 million in the prior fiscal year. Cash and short-term investments increased by $33.9 million to $175.6 million during the twelve-month period. On the basis of our strong balance sheet, validating our belief in the Company’s operational fundamentals, long-term financial prospects and our strong commitment to increase shareholder value, we initiated our fifth share buyback program with a total budget of $50 million to be executed over eighteen months, starting in November 2015. ROFIN continues to keep a strong financial position. Our capital management priorities include investing in the Company’s growth, for example through potential strategic acquisitions and technology prospects and returning capital to shareholders, as appropriate. We believe this balanced approach will enhance shareholder value.

ROFIN’s distinct innovative strength leads to one of the industry’s most comprehensive technology and applications portfolios for laser material processing. In fiscal year 2015, we allocated $40.0 million to research and development in order to further enhance our technological edge and expand our process

Growth Focus: Fiber Lasers

applications and product portfolio to broaden our market reach. We devoted the lion’s share of the resources during the reporting period to the further technological advancement of our high-power fiber lasers as well as into the development of our ultrashort pulse laser series.

We are particularly focused on both of these technologies, because of their expected continuing above average growth rates.

Our strategy to deliver attractive long-term value for shareholders involves maximizing the value of our strong cash-generating core business while investing heavily in the higher growth opportunities in fiber laser and ultrashort pulse lasers.

In terms of fiber lasers, we had a very successful fiscal year, demonstrating that the market recognizes the quality and performance of our lasers and that our initiatives to enhance technological progress and optimize our manufacturing cost structure continue to yield results. In fiscal year 2015, we shipped 1,300 units and our backlog at year-end for fiber laser products amounted to roughly 440 units. Our revenues from fiber laser products contributed over 30% to our overall laser-related sales of $301.4 million. In the high-power range, we were able to increase our unit sales by over 70% compared to the prior fiscal year and we are well-positioned to further ramp up production in the coming years. These results underscore our achievements in the high-power fiber laser market since 2007, when we recognized that fiber laser technology had the potential to develop from a pure, very low-power product in telecommunications to a laser source suited for industrial applications.

Since then, we have invested significantly in research and development, simultaneously ac-quiring capability across the entire production chain for fiber lasers, to build proprietary high-power fiber laser technology and establish vertical integration. The latter is essential to economically manufacturing high-power fiber

laser sources due to the high proportion of diode costs. ROFIN delivered its first fiber laser in the 1 kilowatt (kW) output power range in 2009 and today is able to offer multikilowatt lasers. With our recently released 8 kW model, we believe that we are in an excellent position to address additional markets and gain further market share. Over the course of fiscal year 2015, we improved the yield of our chip material and continued to ramp up our chip production. In order to achieve even higher output power pumping modules in the future, we reinforced our efforts to further optimizing the wafer structure and chip design.

With one of the broadest fiber laser portfolios in the industrial laser space – from single to multikilowatts – and the advantage of vertically integrated production in the high-power fiber laser area, we are well-positioned to further realize attractive return on our investment, drive margin expansion and increase market share. Additionally, ROFIN continues to pursue clear research and development projects in order to reduce manufacturing costs further, as it is our goal to lower these costs by at least a further 15% by the end of fiscal year 2016. We expect to see continued gross margin improvement from these cost-cutting measures, which should be further amplified by benefits from increased production volume and the related economy of scale effects.

We are also gaining momentum with our ultrashort pulse lasers and systems, the second domain in which we are focusing due to expect-ed material growth. These so-called “cold” laser sources in the femto- and picosecond pulse lengths range prevent thermal impacts on the manufactured parts and costly and time-consuming post-processing can be eliminated. Another advantage of these lasers, similar to other solid-state lasers, is the broad range of possible pulse lengths that they command. Ultrashort pulse lasers have additional features, such as frequency doubling or tripling with corresponding change of wavelength, so that the choice of material to be treated is almost unlimited. ROFIN was one of the first movers in this market when this technology matured for economic use in industrial production, and today we possess a complete product-lineup of ultrashort pulse laser sources and turnkey-solutions. Over the past years, the market for ultra-precise material processing tools for miniaturized parts has grown rapidly. Many applications have been made possible only through the use of ultrashort pulse lasers, further accelerating growth in this sector. We see major growth potential for supplementary applications in the medical device, automotive and photovoltaic industries.

In addition, we offer ultrashort pulse lasers in combination with our proprietary Smart-Cleave™FI application, a unique process tech-nology for the high-quality laser cutting of brittle materials by means of laser filamentation.

SmartCleave™FI provides one of the industry’s most advanced process technology, capable of substituting mechanical techniques and opening new markets for ultrashort pulse lasers, such as in the consumer electronics industry to cut strengthened and non-strength-ened cover-glass, ceramics or sapphire. Additional application potential includes the cutting of glass in the automotive, medical and pharmaceutical industries, as well as for displays and architectural glass. In the mid-term, we also see applications in the semiconductor industry. First installations for the cutting of brittle materials were made in Asia and Europe. ROFIN’s SmartCleave technology has the potential to fuel future ultrashort pulse laser business as we expect the order entry for this application to substantially increase over the years to come and contribute to ROFIN’s future growth.

In both key strategic growth areas, high-power fiber lasers and ultrashort pulse lasers, we have made significant progress and realized high growth rates compared to the overall market for industrial laser material processing. We are seeing the tangible results of our significant historical investments in these fields and we believe we are well-positioned for future gains.

Growth Focus: Ultrashort Pulse Lasers

Strong Core Business

In addition to those two growth focuses, we continue to capitalize on a strong and solid core business, comprised of a broad laser product line portfolio of solid-state, diode and CO2 laser technologies, as well as a steadily growing component business that has, over time, become a strong contributor to our overall revenue.

Most of our high-tech components, such as the specialty fibers from our subsidiary Nufern or the semiconductor laser components from our subsidiary DILAS, are both used in-house for the Company’s own product portfolio and integrated by other laser manufacturers into their products, underlining our strong position in the market place. This broad usage of our components enables us to benefit from an overall growing industrial laser market.

Among the highlights of fiscal year 2015 for this part of our Group’s business was the introduction of our new fiber-coupled diode laser system with 6 kilowatt output power, which was developed to address the most demanding customer requirements and to operate in the harshest of processing environments. Principal target applications are thermal applications such as brazing, cladding and hardening in the automotive, aviation and mining industries and their suppliers, to name just a few. These multikilowatt diode lasers round out the Company’s technology offering in the high-power laser range for industrial applications. In fiscal year 2015, we acquired a production facility in Mainz (Germany) for our DILAS subsidiary to secure production space and cleanroom capacity in order to take advantage of the anticipated long-term growth opportunities in this business.

Other highlights during the past fiscal year include advances we have made in low-power lasers for marking and micro processing. We launched several new products including frequency multiplied lasers, such as SHG

(second harmonic generation) and THG (third harmonic generation) lasers (i.e. in the UV range) that, through their wavelengths, allow the processing of very sensitive materials. Those lasers are ideally suited for marking, ablation, drilling and cutting and address promising application areas in the electronics or semiconductor markets as well as in the photovoltaic and consumer electronics industries. In addition, we have several prod-uct development efforts underway, which are expected to further broaden our product portfolio in this area to actively address high potential markets, e.g., with high-precision 3D marking and structuring applications where high peak performances without thermal impact are prerequisites for best production results.

In addition, we see significant continuing growth potential for low-power CO2 lasers in organic material processing applications. The predominance of CO2 lasers in applications such as leather-cutting in the footwear industry, the cutting of technical textiles such as airbags or perforating of foils in the packaging industry is attributed to the specific wavelength of these lasers. Due to the continuing success of our low-power CO2 lasers and their expanding use and demand across a broad range of industries, we started the construction of a new energy-efficient factory in the United Kingdom in fiscal year 2014, where these laser sources are manufactured. We expect to move into the new facility in early 2016. In addition to increased production capacity for these low-power lasers, we expect to benefit from additional synergies, enhanced lean manufacturing and overall improved efficiency through the facility.

We remain committed to strengthening our position as a global player in the growing market for industrial laser material processing by creating innovative new products, continually looking for opportunities to significantly expand

Cost Reduction & Efficiency ProgramsIn fiscal year 2015, we also had a special focus on controlling costs and increasing efficiency. In May 2015, we launched an additional cost saving and efficiency program beyond the measures already implemented. For example, we improved the cost structure in the production of our high-power fiber lasers through the implementation of our third generation design that has improved features and allows for fewer components and therefore reduced costs. In addition, overall higher efficiency in production and higher production volumes along with economies of scales supported the cost cutting effects in this area.

As part of our profitability and efficiency improvement program, we identified possible operational consolidations. In a first set of measures of what we are calling a “smooth consolidation” course, we merged two of our Switzerland-based subsidiaries into a single legal entity. Furthermore, we plan to merge two of our German subsidiaries in order to streamline administrative processes and benefit from synergies. In addition to the positive effects from these measures and from our new production plant for low-power CO2 lasers in Hull (UK), we also expect to see synergies and increased efficiency from the consolidation of our different MICRO sites under one roof in Gilching. The building was acquired in January 2015, and we expect to move in and commence operations latest at the end of calendar 2016.

As we consolidate and decrease our cost structure, we are mindful that our business covers many different technologies and

branches of completely different natures and know-how, depending on the products and industries. Nonetheless, the optimization of our Company structure is an ongoing process, and should provide more positive effects over time.

During this year, we also expanded our leadership team, creating a clear focus on key operational areas such as high-power fiber, ultrashort pulse lasers and the component business, important geographical regions and cost reduction, streamlining of processes and an increase in efficiency.

Lower costs in selling, general and ad-ministration have accompanied our cost-cutting efforts and since we have completed significant research and development projects in both areas of higher growth, we were able to return both of these line items to more normal levels as a percentage of net sales than in the prior year. Expenses for selling, general and administration represented 19% of net sales and expenses related to research and development amounted to 8% of net sales. Our mid-term target is to reduce selling and administration expenses to 18% of net sales, and expenses related to research and development to 7% of net sales. Through these and additional initiatives, we will con-tinue to target further cost control, while simultaneously actively promoting sales and development in key areas and markets.

Coupling these initiatives on the cost side with our strong product portfolio, we expect to see additional operating cost-savings of at least

the utilization of our lasers across the existing multiple end markets and pursuing applications in new markets for these exceptional industrial tools.

Yours sincerely

The Company sells directly to end users and to original equipment manufacturers (“OEMs”) that integrate ROFIN's laser sources with other system components. Many of ROFIN's customers are among the largest global participants in their respective industries. During fiscal 2015, 2014 and 2013, 21%, 19% and 20%, respectively, of the Company’s sales were in North America, 45%, 49% and 45%, respectively, were in Europe, and 34%, 32% and 35%, respectively, were in Asia.

ROFIN's sales approach in the laser-related business reflects the many different requirements of its customers throughout a multitude of industries, and is divided into three areas of core competence: Macro, Micro and Marking. The core of the Macro business section is high-powered laser sources, primarily used for cutting and welding as well as surface treatment applications. The Micro section concentrates on laser sources and laser-based system solutions that require less power output for micro-processing of materials. The Marking section specializes in innovative marking solutions on both organic and inorganic materials for many different industries. The activities in the components sector which comprises of diodes and diode laser components, power supplies, fibers and fiber beam deliveries as well as fiber laser components round out the Company's business activities in the industrial laser market. During fiscal 2015, 2014 and 2013, approximately 38%, 40% and 38%, respectively, of the Company’s revenues related to sales of laser products for macro applications, approximately 47%, 47% and 49%, respectively, related to sales of laser products for marking and micro applications, and approximately 15%, 13% and 13%, respectively, related to sales of components.

 THE INDUSTRIAL LASER MARKET FOR MATERIAL PROCESSING Over the past decades, lasers have revolutionized industrial manufacturing and have been used increasingly to provide reliable, flexible, non-contact, compact and high-speed alternatives to conventional technologies for processing various kinds of metal and non-metal materials in a broad range of advanced manufacturing applications. The industrial laser market is generally considered to be made up of laser sources sold for industrial applications including material processing, medical therapeutic, instrumentation, research, telecommunications, optical storage, entertainment, image recording, inspection, measurement and control, bar-code scanning and other end-uses.

According to the Industrial Laser Solutions magazine's 2015 industry forecast published in January 2015, worldwide laser revenues for industrial material processing applications, which are ROFIN’s primary addressed markets, are expected to reach approximately $2.8 billion. The Company has sold more than 75,000 laser sources since 1975 and currently has over 4,000 active customers (including multinational companies with multiple facilities purchasing from the Company).

BUSINESS STRATEGY The Company's business strategy is to maximize shareholder value by, among other things, (i) strengthening its position as a leading supplier to the global market for macro (cutting and welding) applications; (ii) capitalizing on its leadership position in marking applications; (iii) extending its position in micro (fine cutting, fine welding, perforating and structuring applications); (iv) cross-selling its various laser products to its existing large customer base; (v) enlarging its market coverage geographically and by developing new applications; (vi) strengthening its product portfolio and customer base through acquisitions; (vii) capitalizing on its proprietary application process and technology portfolio; (viii) broadening its component product portfolio; (ix) focusing on continued cost reduction and efficiency improvement in processes and worldwide organizational structure.

 The Company believes that the major sources of its future growth will be the following:

• Developing New Laser Products through Technological Innovation: Product innovation in response to evolving customer needs for increased output power, greater penetration and higher processing speeds is a key component of the Company's strategy. The Company is actively engaged in the research and development of its low- and high-power fiber laser family to further expand its solid-state laser offering for marking, micro and macro applications. The Company is also enhancing its research and development efforts in order to broaden its portfolio of short and ultrashort pulse lasers. The Company is also focusing its research and development activity on expanding the output power range of its CO2, diffusion cooled, wave-guide Slab lasers and enhancing the performance of its line of high power, fast-flow CO2 lasers. In addition, the Company is expanding its series of end and side pumped, solid-state lasers for marking and micro applications. Especially for those lasers there are also activities to enlarge the portfolio by green and ultraviolet ("SHG" and "THG") laser products. In addition, research and development is focused on expanding the Company's product range, especially in the field of passive and active fibers, laser diodes, power supplies and fiber delivery systems.

• Focusing on Cross-Selling to Existing Customers in Target Markets: The Company intends to continue to focus its sales and marketing activities on its traditional target markets (the machine tool, automotive, semiconductor, electronics, photovoltaic, flexible packaging and medical device industries). The Company has targeted and will continue to target these industries because they use advanced manufacturing processes that require continuing investments to improve production efficiency and because the Company has significant market presence in these sectors. In addition, building on the success of its laser marking of small integrated circuits, the Company intends to develop new applications, such as fine welding, cutting and drilling for the semiconductor and electronics industry. In the packaging industry, the Company is seeking new opportunities for foil perforation based on its extensive knowledge of paper perforation with lasers. In the photovoltaic industry, the Company intends to further exploit structuring and annealing applications for its macro and micro laser products such as scribing of thin film solar cells as well as crystalline solar cells. In the consumer electronics and medical device industries, the Company is seeking new opportunities to cut brittle material for various applications such as displays and cover glasses for consumer electronic products, medical glass and architecture glass.

• Capitalizing on Global Presence to Attract New Customers: The Company intends to capitalize on its customer base and the presence of its manufacturing, sales and service operations in the three principal geographic markets in which its customers operate (North America, Europe and the Asia/Pacific region) to increase market share in its existing industrial and geographic markets. The Company believes its global manufacturing, distribution and service network allows it to be more responsive to customers' needs and positions it to expand into additional promising markets which offer high long-term potential for growth.

 

• Offering Customized Solutions based on Standard Platforms: While the Company offers a wide range of laser applications and develops customized solutions for its customers, these applications and solutions are built on a focused number of product families comprised of standardized laser sources. For example, for its OEM customers in the machine tool industry, the Company provides customized laser versions. For its marking customers, the Company combines its standard laser markers with customized parts handling and software. For its micro applications customers, the Company delivers its standard laser sources in different customized packages. The Company believes that this product strategy has contributed to increases in product sales and intends to continue offering focused customization services and pursuing its initiatives to standardize its core products so as to lower its production costs and continue to improve its profitability.

• Acquiring Complementary Business Operations, Products, Applications or Technologies: Besides growing organically, one of ROFIN's targets is to grow through strategic acquisitions. Since 1997 the Company has successfully acquired and integrated fifteen businesses, including its acquisitions of DILAS Diodenlaser GmbH (“DILAS”) (1997), assets of Palomar Technologies UK Ltd. (1998), Rasant-Alcotec Beschichtungstechnik GmbH (“Rasant”) (1999), Baasel Lasertech (“CBL” now "RBL") (2000), Z-Laser S.A. (2001), Optoskand AB (“Optoskand”) (2004), PRC Laser Corporation (“PRC”) and Lee Laser, Inc. (“Lee”) (2004), H2B Photonics GmbH (“H2B”) (2006), ES Technologies Ltd. (2007), Corelase Oy (2007), m2k-laser GmbH (2007), Nufern (2008), Nanjing Eastern Laser Co. Ltd. (“NELC”) (2009), the coil winding business from Optelecom-NKF, Inc. (2010), LASAG AG (“LASAG”) (2011) and assets of FiLaser USA LLC (2014). Management believes that, collectively, these acquisitions have advanced the Company's worldwide expansion, strengthened the Company's position in the industrial laser material processing market and

7

positively contributed to the Company's financial performance during the last several years. The Company will continue to seek opportunities to make value-based acquisitions that complement its business operations, broaden its product offerings, or provide access to new geographical markets and applications.

LASER TECHNOLOGY The term “laser” is an acronym for “Light Amplification by Stimulated Emission of Radiation”. Lasers were first developed in the early 1960s in the United States. A laser consists of an active lasing medium that gives off its own light (radiation) when excited, an optical resonator with a partially-reflective output mirror at one end, a fully-reflective rear mirror at the other that permits the light to bounce back and forth between the mirrors through the lasing medium, and an external energy source used to excite the lasing medium. A laser works by causing the energy source to excite (pump) the lasing medium, which converts the energy from the source into an emission consisting of particles of light (photons). These photons stimulate the release of more photons, as they are reflected between the two mirrors, which form the resonator. The resulting build-up in the number of photons is emitted in the form of a laser beam through an output port or “window”. By changing the energy and the lasing medium, different wavelengths and types of laser light can be produced. The laser produces light from the lasing medium to achieve the desired intensity, uniformity, and wavelength through a series of reflective mirrors. The heat generated by the excitation of the lasing medium is dissipated through a cooling mechanism, which varies according to the type of laser technology.

Lasers are used for material processing because they have many advantages over other conventional production methods. In many areas of industrial manufacturing, lasers already allow for significantly greater precision, flexibility, and productivity and are often the only technology that enables efficient mass production of innovative products. The principal factors that distinguish different types of lasers and determine the particular laser suitable for a specific application, besides economic reasons, are wavelength, pulse duration, output power, and spatial coherence.

The principal types of laser technologies currently used for material processing are CO2 lasers, solid-state lasers, fiber lasers, and diode lasers.

CO2 lasers, which use CO2 gas as the lasing medium, are divided into high-power (above 500 watts) and low-power (below 500 watts) applications. There are two methods for CO2 excitation, radio frequency (“RF” or “HF”) and direct current (“DC”) excitation. Most high-power CO2 lasers are based on gas flow, in which a continuous supply of fresh laser gas flows through the laser cavity to create the energy necessary for excitation. Due to their ability to generate comparatively high levels of continuous-wave (“CW”) power, CO2 lasers are a particularly attractive laser medium for material processing applications. Material processing applications for CO2 laser sources vary according to the power output and configuration of the laser system. The primary applications for high-power CO2 lasers are cutting and welding of metal as well as surface treatment. Low-power CO2 lasers are used principally for marking, cutting and engraving of organic materials. While both low- and high- power CO2 lasers are used for cutting, the materials they are used to process and their physical size can vary significantly.

Traditional solid-state lasers use flash lamps or laser diodes as source of excitation and are referred to as “flash-lamp-pumped” or “diode-pumped” lasers. The lasing medium is a solid-state crystal, generally in the form of a rod or a disc. Widely used crystal rod material is either neodymium yttrium aluminum garnet (Nd:YAG) or neodymium vanadate (Nd:YVO4). The rod is positioned in a cavity, which is either a gold or ceramic reflector, and pumped using flash lamps or laser diodes from the side, or alternatively the rod is pumped from its ends with laser diodes. Typical output powers vary from 3 to 1,000 watts from a single rod and output powers in the multiple kilowatt range can be achieved by combining several cavities within a resonator. In the “disc design” the lasing medium is a thin crystal (typically ytterbium:YAG) disc, which is excited by laser diodes in an optical multi-pass configuration. By using multiple thin disc laser heads within one resonator, several kilowatts of power can be generated.

Fiber lasers are solid-state lasers that have their origin in low-power information and communication applications, and since 2003 have undergone a rapid development towards higher output powers, which has also made this technology very attractive for higher-power material processing applications. The lasing medium, typically ytterbium, is contained in a waveguide (the active fiber itself) and surrounded by a cladding, which guides the pump light to the lasing medium. With in-fiber components like fiber bragg gratings, tapered fiber bundles (pump light couplers), power combiners, and delivery fibers, from the generation of the light to the delivery of the light to the work piece, can be realized in an “all-in-fiber” technology. Today multi kW output power can be generated from a single fiber, no bigger in diameter than a human hair. Higher power can be generated by bundling multiple fibers. Typical industrial applications for solid-state and fiber lasers

8

vary according to the different output powers from marking and engraving, to micro processing such as fine cutting, fine welding or micro-structuring right up to macro processing (cutting, welding and surface treatment).

Solid-state and fiber lasers can be operated in cw, pulsed, q-switched or modelocked mode, covering the pulse width range from cw down to femtoseconds; lasers with pulse widths shorter than 10-8s are often referred to as ultrashort pulse lasers. Over the recent years ultrashort pulse laser technology has matured and today these lasers provide sufficient output power for industrial applications with typical pulse lengths in the range from some ten picoseconds to some 100 femtoseconds. These lasers provide pulses with high peak powers that are shorter than the time needed for most energy diffusion processes within the atomic lattice. Therefore heat transfer to surrounding material is dramatically reduced which eliminates almost all unwanted material change or thermal damage. This is the reason why this method is also referred to as “cold” or “a-thermal” material processing which is suitable for processing extremely sensitive materials. Ultrashort pulse lasers cut, drill and structure virtually any material with micron-scale precision and are perfect tools for applications in the electronics, semiconductor, micro technology, and medical device manufacturing industries.

Diode lasers are based on special semiconductor structures on a gallium arsenide (GaAs) die to generate laser light. A typical 10 mm long laser diode bar contains approximately 25 single laser emitters. When mounted on a specially designed, highly- efficient heat sink, a laser diode bar is able to produce up to 100 watts of laser output power. A single high-power laser diode module consists of: (1) a semiconductor laser diode bar; (2) a high-efficient heat sink, on which the laser bar is mounted; and optional (3) a micro-lens system, which is mounted in front of the laser bar to collimate or focus the light. Optical output power can be increased by combining the beamlets of several laser diode modules on top of each other. Through optical combination of such modules, output powers in the kilowatt range can be achieved. Diode lasers typically have larger spot diameters when focused, and are typically used for surface treatment such as cladding or hardening, for additive manufacturing as well as for soldering and plastic welding.

THE COMPANY’S LASER PRODUCTS The Company distinguishes itself from the majority of its competitors who specialize in only one or two of the three principal laser technologies for material processing by offering its customers CO2, solid-state, fiber, ultrashort pulse and diode laser sources, and solutions in a variety of configurations and options.

 The Company's DQ Series of Q switched, solid-state lasers are designed for applications such as removal, cleaning, and insulation of various materials in the automotive, steel and photovoltaic markets. To meet the different demands of these target markets, DQ Series lasers offer alternative set-up options which differ in power, pulse energy and number of laser sources per unit.

The Company's FL Series of high-brightness single or multi-mode fiber lasers use special fiber optics as the active medium. These fiber lasers are suitable for classic cutting and welding applications as well as for new applications such as remote cutting and scanner welding. In contrast to common laser concepts in which the created laser beam switches repeatedly between air and the active medium, this laser beam does not leave the fiber optic before entering the working process optic or the beam switch with subsequent launching into the working process. Due to this “all-in-fiber” technology, the risk of contamination can be avoided. Beam switches and energy splitters are available options allowing up to four work cells to be operated with only one laser.

The Company's NukW Series products are stand-alone fiber laser amplifiers that are produced and marketed under the Nufern brand. Their principal market is the defense industry, where they are used for advanced applications.

The Company's family of high-power diode laser products for welding and surface treatment applications, and their principal market, are discussed below.

CUSTOMER SERVICE, REPLACEMENT PARTS AND COMPONENTS During fiscal 2015, 2014 and 2013, approximately 42%, 42% and 39%, respectively, of the Company’s revenues were generated from sales of after-sales services, replacement parts and components for laser products. The Company believes that a high level of customer support is necessary to successfully develop and maintain long-term relationships with its OEM- and end-user customers. The Company seeks to maintain this close relationship as its customers’ needs change and evolve. Recognizing the importance of its existing and growing installed multinational customer base, the Company has expanded its local service and support platform into new geographic regions. ROFIN has 430 customer service personnel. The Company’s field service and in-house technical support personnel receive ongoing training with respect to the Company’s laser products, maintenance procedures, laser-operating techniques and processing technology. Most of the Company’s OEM customers also provide customer service and support to end users. Many of ROFIN’s laser products are operated 24 hours a day in high speed, quality-oriented manufacturing operations. Accordingly, the Company provides 24 hour, year-round service support to its customers in the United States, Germany and the majority of other countries in which it operates. The Company plans to continue adopting similar service support elsewhere. In addition, eight-hour response time is provided to certain key customers. This support includes field service personnel who reside in close proximity to the Company’s installed base. The Company provides customers with process diagnostic and verification techniques, as well as specialized training in the operation and maintenance of its systems. The Company also offers regularly scheduled and intensive training programs and customized maintenance contracts for its customers.

Of ROFIN’s 430 customer service personnel, approximately 276 employees operate in the field in about 50 countries. Field service personnel are also involved in the installation of the Company’s systems. ROFIN’s approach to the sale of replacement parts is closely linked to the Company’s strategic focus on rapid customer response. The Company provides around-the-clock order entry and provides same or next day delivery of parts worldwide in order to minimize disruption to customers’ manufacturing operations. ROFIN typically provides a minimum one-year warranty for its products with warranty extensions negotiated on a case-by-case basis; and for after-sales service and parts supply for up to a period of 10 years, if requested by a customer. The Company’s growing base of installed laser sources and laser-based systems is expected to continue to generate a stable source of revenues from sales of replacement parts and after-sales service. In addition, the Company offers components such as OEM-laser modules, optical engines, laser diodes, active and passive fibers, fiber optic delivery systems and power supplies. These high-technology components are either integrated by other laser manufacturers into their products or are used for the Company's own product portfolio.

COMPETITION

The Company believes that as manufacturing industries continue to modernize, seek to reduce production costs and require more precise and flexible production, the features of laser-based systems will become more desirable than systems incorporating conventional material processing techniques and processes. The increased acceptance of these laser applications by industrial users will be enhanced by laser product line expansion to include lower and higher power CO2 lasers, variations in wavelength, advancements in fiber-optic beam delivery systems, improvements in reliability and the introduction of lower and higher power

20

diode lasers, diode pumped, solid-state lasers, short and ultrashort pulse lasers and fiber lasers, capable of performing heavy industrial material processing and marking and micro applications. Laser Macro Products The market for laser macro products and systems is fragmented and addressed by a large number of competitors. Many of them are small or privately owned or compete with ROFIN on a limited geographic, industry- or application-specific basis. The Company also competes in certain target markets with competitors that are part of large industrial groups and have access to substantially greater financial and other resources than ROFIN. The overall competitive position of the Company will depend upon a number of factors, including product performance and reliability, price, customer support, manufacturing quality, the compatibility of its products with existing laser systems, and the continued development of products utilizing diode laser, diode pumped, solid-state laser and fiber laser technologies. Competition among laser manufacturers is also based on attracting and retaining qualified engineering and technical personnel.

ROFIN believes it is among the top three suppliers of laser sources in the worldwide market for macro applications. Companies such as Trumpf and Fanuc (for high-power CO2 lasers), Synrad and Coherent (for low-power CO2 lasers), Trumpf and IPG Photonics (for solid-state or fiber lasers), and Laserline and Jenoptik (for diode lasers and laser diodes) all compete in a subset of markets in which ROFIN operates. However, in the Company's opinion, none of these companies compete in all of the industries, applications and geographic markets currently served by ROFIN.  

Laser Marking and Micro Products The Company's laser marking products compete with conventional ink-based and acid-etching technologies, as well as with laser mask-marking. The Company's micro products compete with conventional welding, etching and spark erosion technologies. The Company believes that its principal competitors in the laser marking and micro markets include Trumpf, GSI Group, Unitek Miyachi, Han's Laser and IPG Photonics. ROFIN also competes with manufacturers of conventional non-laser products in applications such as welding, drilling, cutting and marking.

Significant competitive factors in the market for laser marking and micro products include system performance and flexibility, cost, the size of each manufacturer's installed base, capability for customer support and breadth of product line. Because many of the required components to develop and produce a laser product for marking applications are commercially available, barriers to entry into this market are low and the Company expects new competitive products to enter this market. The Company believes that its product range for marking and micro applications will compete favorably in this market primarily due to performance and price characteristics of such products.

Optical engines for fiber lasers, fiber lasers modules and wafer material are designed and manufactured in Tampere (Finland).

Given the competitive nature of the laser business, the Company focuses substantial efforts on maintaining and enhancing the efficiency and quality of its manufacturing operations. The Company utilizes just-in-time and cell-based manufacturing techniques to reduce manufacturing cycle times and inventory levels, thus enabling it to offer on-time delivery and high-quality products to its customers. ROFIN’s in-house manufacturing includes only those manufacturing operations that are critical to achieve quality standards or protect intellectual property. These manufacturing activities consist primarily of product development, testing of components and subassemblies (some of which are supplied from within the Company and others of which are supplied by third party vendors and then integrated into the Company’s finished products), assembly and final testing of the completed product, as well

21

as proprietary software design and hardware/software integration. Although the Company minimizes the number of suppliers and component types, wherever practicable, it has at least two sources of supply for key items. ROFIN has a qualifying program for its vendors and generally seeks to build long-term relationships with such vendors. The Company purchases certain major components from single suppliers. The Company estimates that 8% of its revenues are from the sale of products that require specialized components currently only available from single sources. ROFIN has written agreements with such suppliers and has not had material delays in supplies from these sources. The Company believes that it could, if necessary, purchase such components from alternative sources, within four to six months, following appropriate qualification of such new vendors. ROFIN is committed to meeting internationally recognized manufacturing standards. Its Hamburg, Gunding-Munich, Starnberg, Mainz, Overath (all Germany), Thun (Switzerland), Gothenburg (Sweden), Monza (Italy), Paris (France), Daventry (UK), Kingston upon Hull (UK), Nanjing (China), Singapore, East Granby, Connecticut, and Tucson, Arizona, facilities are ISO 9001 certified.

RESEARCH AND DEVELOPMENT During fiscal 2015, 2014 and 2013, ROFIN’s net spending on research and development was $40.0 million, $45.9 million and $43.0 million, respectively. The Company’s net spending on research and development reflects receipt of funding mainly under German and other European governments and European Union grants totaling $0.7 million, $1.6 million, and $2.4 million in fiscal 2015, 2014 and 2013, respectively. ROFIN has approximately 290 employees engaged in product research and development. ROFIN’s research and development activities are directed at meeting customers’ manufacturing needs and application processes. Core competencies include solid-state lasers, fiber lasers, ultrashort pulse lasers, CO2 gas lasers, diode lasers, precision optics, electronic power supplies, fibers, fiber optics, beam delivery, control interfaces, software programming, and systems integration. The Company strives for customer-driven development activities and promotes the use of alliances with key customers and joint development programs in a wide range of its target markets.

The Company’s research and development activities are carried out in fifteen centers in Hamburg, Gunding-Munich, Starnberg, Freiburg and Mainz (all Germany), Kingston upon Hull (UK), Gothenburg (Sweden), Tampere (Finland), Thun (Switzerland), Plymouth, Michigan, Landing, New Jersey, Orlando, Florida, Tucson, Arizona, East Granby, Connecticut, and Nanjing (China), and are centrally coordinated and managed. ROFIN maintains close working relationships with the leading industrial, government and university research laboratories in Germany, including the Fraunhofer Institute for Laser Technology in Aachen, the Institute for “Technische Physik” of the German Space and Aerospace Research Center in Stuttgart, the Fraunhofer Institute for Applied Solid State Physics in Freiburg, the Fraunhofer Institute for Material Science in Dresden, the Laser Center in Hanover (all Germany), and elsewhere around the world, including the University of Edinburgh in the United Kingdom, Tampere University of Technology in Finland, and University of Bern in Switzerland. These relationships include funding of research, joint development programs, personnel exchange programs, and licensing of patents developed at these institutes.

INTELLECTUAL PROPERTY ROFIN owns intellectual property, which includes patents, proprietary software, technical know-how and expertise, designs, process techniques and inventions. While policies and procedures are in place to protect critical intellectual property rights, ROFIN believes that its success depends to a larger extent on the innovative skills, know-how, technical competence and abilities of ROFIN’s personnel. ROFIN protects its intellectual property in a number of ways including, in certain circumstances, through patents. ROFIN has sought patent protection primarily in the United States, Europe and Asia. ROFIN currently holds 262 patents for inventions relating to lasers, processes and power supplies with expiration dates ranging from 2015 to 2034. In addition, 204 patent applications have been filed and are under review by the relevant patent authorities. The Company holds 39 exclusive and non-exclusive licenses of patents and pending patent applications with relevance to its products and laser technology. ROFIN requires its employees and certain of its customers, suppliers, representatives, agents and consultants to enter into confidentiality agreements to further safeguard ROFIN’s intellectual property. ROFIN, from time to time, receives notices from third parties alleging infringement of such parties’ patent or other intellectual property rights by ROFIN’s products. While these notices are common in the laser industry and ROFIN has in the past been

22

able to develop non-infringing technology or license necessary patents or technology on commercially reasonable terms, ROFIN cannot assure that it would in the future prevail in any litigation seeking damages or expenses from ROFIN or to enjoin ROFIN from selling its products on the basis of such alleged infringement. Nor can ROFIN assure that it would be able to develop any non-infringing technology or to license any valid and infringed patents on commercially reasonable terms. In the event any third party made a valid claim against ROFIN or its customers and a license were not made available to ROFIN on commercially reasonable terms, ROFIN would be adversely affected. From time to time, ROFIN files notices of opposition to certain patents on laser technologies held by others, including academic institutions and competitors of ROFIN, which the Company believes could inhibit its ability to develop laser products for industrial material processing applications.

ORDER BACKLOG The Company’s order backlog was $144.3 million, $141.3 million and $118.0 million, as of September 30, 2015, 2014 and 2013, respectively. The Company’s order backlog, which contains relatively little service, training and spare parts, represents approximately three months of laser shipments. The order backlog as of September 30, 2015, consists of a 4% higher order backlog for macro applications, a minor increase in order backlog for micro and marking applications of less than 1%, and a 4% higher order backlog for components compared to the order backlog as of September 30, 2014. The fluctuation of the U.S. dollar in fiscal year 2015 had an unfavorable effect of approximately $13.1 million on year-to-year order backlog. The increase in the Company's order backlog as of September 30, 2014 compared to September 30, 2013, was attributable to 18% higher order backlog for macro applications, 18% higher order backlog for micro and marking applications, and a 35% higher order backlog for components. The fluctuation of the U.S. dollar in fiscal year 2014 had a favorable effect of approximately $2.2 million on year-to-year order backlog.  An order is entered into backlog by ROFIN when a purchase order with an assigned delivery date has been received. Delivery schedules range from one week to six months, depending on the size, complexity and availability of the product or system ordered, although typical delivery dates for laser source products range between one to twelve weeks from the date an order is placed. Although there is a risk that customers may cancel or delay delivery of their orders, orders for standard non-customized lasers can typically be allocated to other customers without significant additional costs. The Company also manages this risk by establishing the right to charge a cancellation fee that covers any material and developmental costs incurred prior to the order being canceled. Enforcement of this right is dependent on many factors including, but not limited to, the customer’s requested length of delay, the number of other outstanding orders and the order and sales history with the same customer, and the ability to quickly convert the canceled order to another sale. The Company anticipates shipping the present backlog during fiscal year 2016. However, the Company’s backlog at any given date is not necessarily indicative of actual sales for any future period.

EMPLOYEES The following table sets forth the Company's employees by geographic regions as of September 30, 2015 and 2014:

September 30,2015 2014

North America 399 425Germany 1,041 1,066Asia 327 320Other 464 459

2,231 2,270

The average number of employees for the fiscal year ended September 30, 2015 was 2,255.

While the Company’s employees are not covered by collective bargaining agreements and the Company has never experienced a work stoppage, slowdown or strike, the Company’s employees at its Hamburg and Starnberg (both Germany) facilities are each represented by a nine-person works council and in Gunding-Munich (Germany) by a seven-person works council. Additionally, Hamburg and Gunding-Munich are represented by a four-person central works council. Matters relating

23

to compensation, benefits and work rules are negotiated and resolved between management and the works council for the relevant location. The Company considers its relations with its employees to be good.

GOVERNMENT REGULATION The majority of the Company’s laser products sold in the United States are classified as Class IV Laser Products under applicable rules and regulations of the Center for Devices and Radiological Health (“CDRH”) of the U.S. Food and Drug Administration. The same classification system is applied in the European markets. Safety rules are formulated with “Deutsche Industrie Norm” (i.e., German Industrial Standards) or ISO standards, which are internationally harmonized.

CDRH regulations generally require a self-certification procedure pursuant to which, for each product incorporating a laser device, a manufacturer must file periodic reporting of sales and purchases, and compliance with product labeling standards with CDRH. The Company’s laser products for macro, micro and laser marking applications can result in injury to human tissue if directed at an individual or otherwise misused. The Company believes that its laser products for macro, micro and marking applications, and its components are in substantial compliance with all applicable laws for the manufacture of laser devices.

In August 2012, the U.S. Securities and Exchange Commission (SEC) issued a rule under Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act requiring companies to publicly disclose their use of conflict minerals that originated in the Democratic Republic of the Congo (DRC) or an adjoining country. Under the rule, issuers are required to conduct a “reasonable” due diligence process to ascertain the source of conflict minerals, defined as tantalum, tin, gold or tungsten, that are necessary to the functionality or production of their manufactured or contracted to be manufactured products. Companies are required to provide this disclosure on Form SD filed with the SEC. The Company filed its Form SD on June 1, 2015 for the 2014 calendar period.

ITEM 1A.           RISK FACTORS THE GLOBAL ECONOMY, CAPITAL MARKETS, CREDIT DISRUPTIONS AND POLITICAL ENVIRONMENT CHANGES CAN ADVERSELY IMPACT OUR RESULTS OF OPERATIONS. Our business, operating results, or financial condition can be impacted by a number of macroeconomic factors, which could in turn affect our stock price. These macroeconomic factors include, but are not limited to, consumer confidence and spending levels, unemployment, consumer credit availability, global factory production and credit market conditions. Additionally, changes in the political environment in the markets in which we operate can adversely impact our business, such as foreign exchange import and export controls, tariffs and other trade barriers and price or exchange controls.

 DOWNTURNS IN THE INDUSTRIES WE SERVE, PARTICULARLY IN THE MACHINE TOOL, AUTOMOTIVE, SEMICONDUCTOR, ELECTRONICS AND PHOTOVOLTAIC INDUSTRIES, MAY HAVE A MATERIAL ADVERSE EFFECT ON OUR SALES AND PROFITABILITY. Our business depends substantially upon capital expenditures particularly by manufacturers in the machine tool, automotive (and sub-suppliers), semiconductor, electronics and photovoltaic industries. Approximately 70% of our laser sales during fiscal year 2015 were to these industry markets. These industries are cyclical and have historically experienced periods of oversupply, resulting in significantly reduced demand for capital equipment, including the products manufactured and marketed by us. For the foreseeable future, our operations will continue to depend upon capital expenditures in these industries, which, in turn, depend upon the market demand for their products. Decreased demand from manufacturers in these industries, for example, during an economic downturn, may lead to decreased demand for our products. Although such decreased demand would reduce our sales, we may not be able to reduce expenses quickly, due in part to the need for continual investment in research and development and the need to maintain our extensive ongoing customer service and support capability. Although we order materials for assembly in response to firm orders, the lead time for assembly and delivery of some of our products creates a risk that we may incur expenditures or purchase inventories for products which we cannot sell.

Accordingly, any economic downturn or slowdown in the machine tool, automotive, semiconductor, electronics or photovoltaic industries could have a material adverse effect on our financial condition and results of operations.

 A HIGH PERCENTAGE OF OUR SALES ARE OVERSEAS AND OUR RESULTS ARE THEREFORE SUBJECT TO THE IMPACT OF EXCHANGE RATE FLUCTUATIONS. Although we report our results in U.S. dollars, approximately 67% of our current sales are denominated in other currencies, including the Euro, Swedish krona, Swiss francs, British pound, Singapore dollar, Japanese yen, Korean won, Taiwanese dollar, Canadian dollar, Indian rupee, and Chinese RMB. The fluctuation of the Euro, and the other functional currencies, against the U.S. dollar has had the effect of increasing and decreasing (as applicable) reported net sales as well as cost of goods sold, gross margin, and selling, general and administrative expenses denominated in such foreign currencies when translated into U.S. dollars as compared to prior periods. We also face transaction risk from fluctuations in exchange rates between the various currencies in which we do business. We believe that a certain portion of the transaction risk of our operations in multiple currencies is mitigated by our hedging activities, utilizing forward exchange contracts and forward exchange options. We also continue to borrow in many of our operating subsidiaries' functional currencies to reduce exposure to exchange gains and losses. However, there can be no assurance that changes in currency exchange rates will not have a material adverse effect on our business, financial condition and results of operations. 

25

OUR INABILITY TO MANAGE THE RISKS ASSOCIATED WITH OUR INTERNATIONAL OPERATIONS COULD ADVERSELY AFFECT OUR BUSINESS. Our products are currently marketed in approximately 70 countries, with the United States, Germany, the rest of Europe and the Asia/Pacific region being our principal markets. Our operations and sales in our principal markets are subject to risks inherent in international business activities, including: 

• the general political and economic conditions in each such country or region; 

• overlap of differing tax structures; 

• climatic or other natural disasters in regions where we operate;

• increases in shipping costs or increases in fuel costs;

• longer payment cycles;

• acts of terrorism;

• increased vulnerability to the theft of, and reduced protection for intellectual property rights;

• management of an organization spread over various jurisdictions; and 

• unexpected changes in regulatory requirements and compliance with a variety of foreign laws and regulations, such as import and export licensing requirements, trade restrictions, currency control and restrictions, delays, penalties or required withholdings on repatriation of earnings.

 Any failure to manage the risks associated with our international business operations could have a material adverse effect on our financial condition and results of operations. Our profitability may be adversely affected by economic slowdowns in the United States, Europe or the Asia/Pacific region.  A recession in these economies could trigger a decline in laser sales to the machine tool, automotive, semiconductor, electronics or photovoltaic industries, and any related weaknesses in their respective currencies could adversely affect customer demand for our products, the U.S. dollar value of our foreign currency denominated sales, and ultimately our consolidated results of operations.

We also are subject to risks that our operations outside the United States could be conducted by our employees, contractors, service providers, representatives or agents in ways that violate the Foreign Corrupt Practices Act or other similar anti-bribery laws. Any such violations could have a negative impact on our business and could result in government investigations and/or injunctive, monetary or other penalties. Moreover, we face additional risks that our anti-bribery policy and procedures may be violated by third-party sales representatives or other agents that help sell our products or provide other services, because such representatives or agents are not our employees and it may be more difficult to oversee their conduct.

OUR GLOBAL OPERATIONS ARE SUBJECT TO EXTENSIVE AND COMPLEX IMPORT AND EXPORT RULES THAT VARY AMONG THE LEGAL JURISDICTIONS IN WHICH WE OPERATE. FAILURE TO COMPLY WITH THESE RULES COULD RESULT IN SUBSTANTIAL PENALTIES.

Due to the international scope of our operations, we are subject to a complex system of import- and export-related laws and regulations, including U.S. export control and customs regulations and customs regulations of other countries. These regulations are complex and vary among the legal jurisdictions in which we operate. Any alleged or actual failure to comply with such regulations may subject us to government scrutiny, investigation and civil and criminal penalties, and may limit our ability to import or export our products or to provide services outside the United States. Depending on its size and scope, any of these penalties could have a material impact on our financial position, results of operations and cash flows.

26

WE DEPEND ON THE ABILITY OF OUR OEM CUSTOMERS TO INCORPORATE OUR LASER PRODUCTS INTO THEIR SYSTEMS. Our sales depend in part upon the ability of our OEM customers to develop and sell systems that incorporate our laser products. Adverse economic conditions, inadequate liquidity, large inventory positions, limited marketing resources and other factors affecting these OEM customers could subject us to risks of business failure by such customers and potential credit and inventory risks, and thus could have a substantial impact upon our financial results. We cannot provide assurances that our OEM customers will not experience financial or other difficulties that could adversely affect their operations and, in turn, our financial condition or results of operations. 

WE EXPERIENCED IN THE PAST, AND EXPECT TO EXPERIENCE IN THE FUTURE, FLUCTUATIONS IN OUR QUARTERLY RESULTS. THESE FLUCTUATIONS MAY INCREASE THE VOLATILITY OF OUR STOCK PRICE. We have experienced and expect to continue to experience some fluctuations in our quarterly results. We believe that fluctuations in quarterly results may cause the market prices of our common stock, on the NASDAQ Global Select Market and the Frankfurt Stock Exchange, to fluctuate, perhaps substantially. Factors which may have an influence on the Company’s operating results in a particular quarter include: 

• general economic uncertainties; 

• fluctuations in demand for, and sales of, our products or prolonged downturns in the industries that we serve; 

• the timing of the receipt of orders from major customers; 

• product mix;

• competitive pricing pressures; 

• the relative proportions of domestic and international sales; 

• our ability to design, manufacture and introduce new products on a cost-effective and timely basis; 

• the delayed effect of incurrence of expenses to develop and improve marketing and service capabilities; 

• foreign currency fluctuations; 

• ability of our suppliers to produce and deliver components and parts, including sole or limited source components, in a timely manner, in the quantity desired and at the prices we have budgeted; 

• our ability to control expenses; and 

• costs related to acquisitions of businesses. These and other factors make it difficult for us to release precise predictions regarding the development and financial results of our business. In addition, current conditions in the domestic and global economies are uncertain, i.e. currently in Asia, especially in China. As a result, it is difficult to estimate the level of growth for the economy as a whole or of capital expenditures in the industrial markets we serve. Because all of the components of our budgeting and forecasting are dependent on estimates of spending within these markets, the prevailing economic uncertainty renders estimates of future revenue and expenses even more difficult than usual to make. In addition, our backlog at any given time is not necessarily indicative of actual sales for any succeeding period. As our delivery schedule typically ranges from one week to six months, our sales will often reflect orders shipped in the same quarter that they are received. Moreover, customers may cancel or reschedule shipments and production difficulties could delay shipments. Accordingly, the Company’s results of operations are subject to significant fluctuations from quarter to quarter. See also “Business - Order Backlog”.

Other factors that we believe may cause the market price of our common stock to fluctuate, perhaps substantially, include announcements of new products, technologies, or customers by us or our competitors, developments with respect to intellectual property, and shortfalls in our operations relative to analysts’ expectations. In addition, in recent years, the stock market in general, and the shares of technology companies in particular, have experienced wide price fluctuations. These broad market and industry fluctuations, particularly in the semiconductor, electronics, photovoltaics, machine tool and automotive industries,

27

may adversely affect the market prices of our common stock on the NASDAQ Global Select Market and the Frankfurt Stock Exchange. 

THE MARKETS FOR OUR PRODUCTS ARE HIGHLY COMPETITIVE AND INCREASED COMPETITION COULD INCREASE OUR COSTS, REDUCE OUR SALES OR CAUSE US TO LOSE MARKET SHARE. The laser industry is characterized by significant price and technical competition. Our current and proposed laser products for macro, marking and micro applications, and components, compete with those of several well-established companies, some of which are larger and have substantially greater financial, managerial and technical resources, more extensive distribution and service networks and larger installed customer bases than us. We believe that competition will be particularly intense in the solid-state, fiber, CO2 and diode laser markets, as many companies have committed significant research and development resources to pursue opportunities in these markets. There can be no assurance that we will successfully differentiate our current and proposed products from the products of our competitors or that the marketplace will consider our products to be superior to competing products. Because many of the components required to develop and produce a laser-based marking system are commercially available, barriers to entry into this market are relatively low, and we expect new competitive product entries in this market. To maintain our competitive position in these markets, we believe that we will be required to continue a high level of investment in engineering, research and development, marketing, and customer service and support. There can be no assurance that we will have sufficient resources to continue to make these investments, that we will be able to make the technological advances necessary to maintain our competitive position, or that our products will receive market acceptance. See also “Business - Competition”. 

OUR FUTURE GROWTH AND COMPETITIVENESS DEPEND UPON OUR ABILITY TO DEVELOP NEW AND ENHANCED PRODUCTS TO MEET MARKET DEMAND AND TO INCREASE OUR MARKET SHARE FOR LASER MACRO AND MARKING AND MICRO PRODUCTS. If we are to increase our laser sales in the near term, these sales will have to come through increases in market share for our existing products, through the development of new products, or through the acquisition of competitors or their products. To date, a substantial portion of our revenues has been derived from sales of high-powered solid-state lasers, fiber lasers, CO2 laser sources and diode lasers. In order to increase market demand for these products, we will need to devote substantial resources to: 

• continuing to broaden our fiber, solid-sate, CO2 and diode laser product range; 

• continuing to increase the output power and vary the laser wavelengths of our product portfolio; and 

• continuing to reduce the manufacturing costs of our product range to achieve more attractive pricing. A large part of our growth strategy depends upon being able to increase our worldwide market share for laser macro, marking and micro products.

Our future success depends on our ability to anticipate our customers’ needs and develop products that address those needs. Our ability to control costs is limited by our need to invest in research and development. If we are unable to implement our strategy to develop new and enhanced products, our business, operating results and financial condition could be adversely affected. We cannot provide assurance that we will successfully implement our business strategy or that any of the newly developed or enhanced products will achieve market acceptance or not be rendered obsolete or uncompetitive by products of other companies. See also “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Business - The Company’s Laser Products”. 

WE DEPEND ON OUR EXECUTIVE MANAGEMENT TEAM AND SKILLED PERSONNEL TO OPERATE OUR BUSINESS EFFECTIVELY IN A RAPIDLY CHANGING MARKET, AND IF WE ARE UNABLE TO RETAIN EXISTING OR HIRE ADDITIONAL PERSONNEL WHEN NEEDED, OUR ABILITY TO DEVELOP AND SELL OUR PRODUCTS COULD BE HARMED. Our future success depends in large part upon the leadership and performance of our executive management team and key employees at the operating level. These key employees include engineering, sales, marketing, manufacturing and support

28

personnel for our operations on a worldwide basis. Recruiting and retaining highly skilled personnel in certain functions continues to be difficult. At certain locations where we operate, the cost of living is extremely high and it may be difficult to retain key employees and management at a reasonable cost. We may not be successful in attracting, assimilating or retaining qualified personnel to fulfill our current or future needs. If we fail to attract additional employees or lose the services of one or more of our executive officers or key employees, or if one or more of them decide to join a competitor or otherwise compete directly or indirectly with us, we may not be able to successfully manage our business or achieve our business objectives. If we lose the services of any of our key employees at the operating or regional level, we may not be able to replace them with similarly qualified personnel, which could harm our business. 

RECENT CHANGES IN OUR EXECUTIVE AND SENIOR MANAGEMENT TEAM MAY BE DISRUPTIVE TO, OR CAUSE UNCERTAINTY IN, OUR BUSINESS, RESULTS OF OPERATIONS, FINANCIAL CONDITION AND THE MARKET PRICE OF OUR COMMON STOCK.

Effective on July 1, 2015, Thomas Merk succeeded Günther Braun as President and Chief Executive Officer of the Company, and at the same time Mr. Merk replaced Mr. Braun as a member of the Board of Directors. In addition to these changes, we have also recently implemented a broader senior management team. These changes in our executive and senior management team may be disruptive to, or cause uncertainty in, our business. In addition, the departure of Mr. Braun, and the failure to ensure a smooth transition and effective transfer of knowledge involving senior employees, could hinder our strategic planning and execution. Any such disruption or uncertainty could have an adverse impact on our results of operations, financial condition and the market price of our common stock.

WE MAY NOT BE ABLE TO SUCCESSFULLY ACQUIRE NEW OPERATIONS OR INTEGRATE FUTURE ACQUISITIONS, WHICH COULD CAUSE OUR BUSINESS TO SUFFER. An important part of our growth strategy is making strategic acquisitions of companies with complementary operations, technologies or products. We regularly review potential acquisitions and periodically engage in discussions regarding such possible acquisitions. We may be unable to successfully complete potential strategic acquisitions if we cannot reach agreement on acceptable terms or for other reasons. Future acquisitions may require us to obtain additional debt or equity financing, which may not be available on terms acceptable to us, if at all. In connection with future acquisitions, we may assume the liabilities of the companies we acquire. Any debt that we incur to pay for future acquisition could contain covenants that restrict the manner in which we operate our business. Any new equity securities that we issue for this purpose would be dilutive to our existing stockholders. If we buy a company or a division of a company, we may experience difficulty integrating that company or division’s personnel and operations, which could negatively affect our operating results. In addition:

• the key personnel of the acquired company may decide not to work for us; 

• we may experience additional financial and accounting challenges and complexities in areas such as tax planning, treasury management and financial reporting; 

• we may be held liable for risks and liabilities (including for environmental-related costs) as a result of our acquisitions, some of which we may not discover during our due diligence; 

• our ongoing business may be disrupted or receive insufficient management attention; and 

• we may not be able to realize the synergies, cost savings or other financial benefits we anticipated.

PRODUCTION DIFFICULTIES AND PRODUCT DELIVERY DELAYS OR DISRUPTIONS COULD HAVE A MATERIAL ADVERSE EFFECT ON OUR BUSINESS.

We manufacture and test our products at our facilities in Germany, the United States, the United Kingdom, China, Finland, Sweden, Switzerland and Singapore. If use of any of our manufacturing facilities were interrupted by a natural disaster or otherwise, our operations would be negatively impacted until we could establish alternative production and service operations. Significant production difficulties could be the result of:

29

• mistakes made while transferring manufacturing processes between locations;

• changing process technologies;

• ramping production;

• installing new equipment at our manufacturing facilities; and

• shortage of key components. In addition, we may experience product delivery delays in the future. A significant disruption in third-party package delivery and import/export services, or significant increases in prices for those services, could interfere with our ability to ship products, increase our costs and lower our profitability.

We ship a significant portion of our products to our customers through independent package delivery and import/export companies. We also ship our products through national trucking firms, overnight carrier services and local delivery practices. If one or more of the package delivery or import/export providers experiences a significant disruption in services or institutes a significant price increase, the delivery of our products could be prevented or delayed. Such events could cause us to incur increased shipping costs that could not be passed on to our customers, negatively impacting our profitability and our relationships with certain customers.

THE ANNOUNCEMENT OF AND ANY FAILURE TO SUCCESSFULLY IMPLEMENT PROFITABILITY ENHANCEMENT PROGRAMS AND COST REDUCTIONS COULD ADVERSELY AFFECT OUR BUSINESS.

From time to time, we have implemented various profitability enhancement and cost reduction initiatives, including the efficiency and cost reduction programs that we announced in the second quarter of fiscal year 2015. These initiatives include evaluating the manufacturing of some products in lower cost regions, the consolidation of various facilities and operations, transitioning higher-cost external supply to internal manufacturing, working with our material suppliers to further lower costs, evaluation the appropriate business staffing levels and streamlining our overhead.

We cannot be sure that our cost reduction initiatives will be successfully or timely implemented, or that they will materially and positively impact our profitability. The cost reductions could adversely impact productivity and sales to an extent we have not anticipated. Even if we fully execute and implement these activities and they generate the anticipated cost savings, there may be other unforeseeable and unintended factors or consequences that could adversely impact our profitability and business.

IF WE FAIL TO ACCURATELY FORECAST COMPONENT AND MATERIAL REQUIREMENTS FOR OUR PRODUCTS, WE COULD INCUR ADDITIONAL COSTS AND INCUR SIGNIFICANT DELAYS IN SHIPMENTS, WHICH COULD RESULT IN A LOSS OF CUSTOMERS. We use rolling forecasts based on anticipated product orders and material requirements planning systems to determine our product requirements. It is very important that we accurately predict both the demand for our products and the lead times required to obtain the necessary components and materials. We depend on our suppliers for most of our product components and materials. Lead times for components and materials that we order vary significantly and depend on factors including the specific supplier requirements, the size of the order, contract terms, and current market demand for components. For substantial increases in our sales levels of certain products, some of our suppliers may need at least a nine-month lead time. If we over estimate our component and material requirements, we may have excess inventory, which would increase our costs. If we underestimate our component and material requirements, we may have inadequate inventory, which could interrupt and delay delivery of our products to our customers. Any of these occurrences would negatively impact our net sales, business, or operating results.

WE DEPEND ON LIMITED SOURCE SUPPLIERS THAT COULD CAUSE SUBSTANTIAL MANUFACTURING DELAYS AND INCREASE OUR COSTS IF A DISRUPTION IN SUPPLY OCCURS. We estimate that 8% of our revenues in fiscal 2015 were derived from sales of products that require specialized components only available from single sources. We also rely on a limited number of independent contractors to manufacture subassemblies

30

for some of our products. There can be no assurance that, in the future, our current or alternative sources will be able to meet all of our demands on a timely basis. If one or more of our suppliers or subcontractors experiences difficulties that result in a reduction or interruption in supply to us, or if they fail to meet any of our manufacturing requirements, our business could be harmed until we are able to secure alternative sources, if any. If we are unable to find necessary parts or components on commercially reasonable terms, we could be required to reengineer our products to accommodate available substitutions which could increase our costs and/or have a material adverse effect on manufacturing schedules, product performance and market acceptance. The manufacturing of our solid-state lasers require elements of rare earth in small quantities. Shortages of these elements, delays in their delivery and resulting increases of the market price for such materials might have an adverse effect on our production costs. 

IF OUR GOODWILL OR OTHER INTANGIBLE ASSETS BECOME IMPAIRED, WE MAY BE REQUIRED TO RECORD A SIGNIFICANT CHARGE TO EARNINGS. Under accounting principles generally accepted in the United States, we review our intangible assets, subject to amortization, for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. Goodwill is required to be tested for impairment at least annually. Factors that may be considered a change in circumstances indicating that the carrying value of our goodwill or other intangible assets may not be recoverable include declines in our stock price and market capitalization or future cash flow projections. A decline in our stock price, or any other adverse change in market conditions, particularly if such change has the effect of changing one of the critical assumptions or estimates we used to calculate the estimated fair value of our reporting units, could result in a change to the estimation of fair value that could result in an impairment charge. Any such material charges, whether related to goodwill or purchased intangible assets, may have a material negative impact on our financial and operating results.

WE COULD BE NEGATIVELY AFFECTED AS A RESULT OF A PROXY FIGHT.

In October 2015, we received notice from SilverArrow Capital Advisors LLP, SilverArrow Capital Holding Ltd., SAC Jupiter Holding Ltd., Pluto Fund Limited, Thomas Limberger, Robert Schimanko, Abdullah Saleh A. Kamel, Osama H. Al Sayed and Ernesto Palomba (collectively “SliverArrow”) (which reports that it owns over 9% of our common stock) declaring its intention to nominate three new independent directors at the Company’s 2016 annual meeting of stockholders. A proxy contest could negatively affect us because: responding to proxy contests, litigation and other actions by dissident shareholders can be costly and time-consuming, disrupting our operations and diverting the attention of management and our employees; perceived uncertainties as to our future direction may divert the attention of, damage morale and create instability among our business partners, management, and employees and adversely impact our existing and potential strategic and operational relationships and opportunities; we may experience difficulties in hiring, retaining and motivating personnel during the resulting uncertain and turbulent times; if individuals are elected to our Board with a specific agenda, it may adversely affect our ability to effectively and timely implement our current business plan which could have a material adverse effect on our results of operations and financial condition; increases in legal fees, administrative and associated costs incurred in connection with responding to a proxy contest and related litigation could be substantial; and  a proxy contest, or the threat of one, could cause our stock price to experience periods of volatility or stagnation.

WE ARE EXPOSED TO LAWSUITS IN THE NORMAL COURSE OF BUSINESS WHICH COULD HAVE A MATERIAL ADVERSE EFFECT ON OUR BUSINESS, OPERATING RESULTS, OR FINANCIAL CONDITION. We are exposed to lawsuits in the normal course of our business, including product liability claims, if personal injury, death or commercial losses occur from the use of our products. While we typically maintain business insurance, including directors' and officers' policies, litigation can be expensive, lengthy and disruptive to normal business operations, including the potential impact of indemnification obligations for individuals named in any such lawsuits. We may not, however, be able to secure insurance coverage on terms acceptable to us in the future. Moreover, the results of complex legal proceedings are difficult to predict. An unfavorable resolution of a particular lawsuit, including a recall or redesign of products if ultimately determined to be defective, could have a material adverse effect on our business, operating results or financial condition.

ANY DEFECTS IN OUR PRODUCTS OR CUSTOMER PROBLEMS ARISING FROM THE USE OF OUR PRODUCTS MAY SERIOUSLY HARM OUR BUSINESS AND REPUTATION.

31

Our laser products are technologically complex and may contain both known and undetected errors or performance problems. In addition, performance problems can also be caused by the improper installation or use of our products by a customer. These errors or performance problems could result in customer dissatisfaction, which could harm our sales or customer relationships. In addition, these problems may cause us to incur significant warranty and repair costs and divert the attention of our engineering personnel from our product development efforts.

THE LONG SALES CYCLES FOR OUR PRODUCTS MAY CAUSE US TO INCUR SIGNIFICANT EXPENSES WITHOUT OFFSETTING REVENUES. Customers often view the purchase of our products as a significant and strategic decision. As a result, customers typically expend significant effort in evaluating, testing and qualifying our products before making a decision to purchase them, resulting in a lengthy initial sales cycle. While our customers are evaluating our products and before they place an order with us, we may incur substantial sales and marketing and research and development expenses to customize our products to the customer's needs. We may also expend significant management efforts, increase manufacturing capacity and order long lead-time components or materials prior to receiving an order. Even after this evaluation process, a potential customer may not purchase our products. As a result, these long sales cycles may cause us to incur significant expenses without ever receiving revenue to offset such expenses.

OUR FAILURE TO PROTECT OUR PROPRIETARY TECHNOLOGY OR TO AVOID LITIGATION FOR INFRINGEMENT OR MISAPPROPRIATION OF PROPRIETARY RIGHTS OF THIRD PARTIES COULD RESULT IN A LOSS OF REVENUES AND PROFITS. Our future success depends in part upon our intellectual property rights, including trade secrets, know-how and continuing technological innovation. There can be no assurance that the steps taken by us to protect our intellectual property rights will be adequate to prevent misappropriation or that others will not develop competitive technologies or products. We currently hold 262 United States and foreign patents on our laser sources and laser applications, with expiration dates ranging from 2015 to 2034. We have also obtained licenses under certain patents covering lasers and related technology incorporated into our products. In addition, 204 patent applications have been filed and are under review by the relevant patent authorities. There can be no assurance that other companies are not investigating or developing other technologies that are similar to ours, that any patents will issue from any application filed by us or that, if patents do issue, the claims allowed will be sufficiently broad to deter or prohibit others from marketing similar products. In addition, there can be no assurance that any patents issued to us will not be challenged, invalidated or circumvented, or that the rights thereunder will provide a competitive advantage to us. See also “Business - Intellectual Property”. From time to time, we receive notices from third parties alleging infringement of such parties’ patent or other proprietary rights by our products. While these notices are common in the laser industry and we have in the past been able to develop non-infringing technology or license necessary patents or technology on commercially reasonable terms, there can be no assurance that we would in the future prevail in any litigation seeking damages or expenses from us or to enjoin us from selling products on the basis of such alleged infringement, or that we would be able to develop any non-infringing technology or license any valid and infringed patents on commercially reasonable terms. In the event any third party made a valid claim against us or our customers and a license was not made available to us on commercially reasonable terms, we would be adversely affected.

CHANGES IN GOVERNMENTAL REGULATION OF OUR BUSINESS OR OUR PRODUCTS COULD REDUCE DEMAND FOR OUR PRODUCTS OR INCREASE OUR EXPENSES.

We are subject to many governmental regulations, including but not limited to the laser radiation safety regulations of the Radiation Control for Health and Safety Act administered by the National Center for Devices and Radiological Health, a branch of the United States Food and Drug Administration. Among other things, these regulations require us to file annual reports, to maintain quality control and sales records, to perform product testing, to distribute appropriate operating manuals, to conduct safety reviews, to incorporate design and operating features in products sold to end users, and to certify and label our products. We are also subject to regulatory oversight, including comparable enforcement remedies, in the markets we serve.

On August 22, 2012, the SEC adopted a new rule requiring disclosures by public companies of specified minerals, known as conflict minerals, that are necessary to the functionality or production of products manufactured or contracted to be

32

manufactured. The new rule, which went into effect for calendar year 2013 and requires annual disclosure reports to be filed with the SEC, requires companies to perform due diligence, disclose and report whether or not such minerals originate from the Democratic Republic of Congo or an adjoining country. The new rule could affect sourcing at competitive prices and availability in sufficient quantities of certain minerals used in the manufacture of our products, including tin, tungsten, tantalum and/or gold. The number of suppliers who provide conflict-free minerals may be limited. In addition, there may be material costs associated with complying with the disclosure requirements, such as costs related to the due diligence process of determining the source of certain minerals used in our products, as well as costs of possible changes to products, processes or sources of supply as a consequence of such verification activities. As our supply chain is complex, we may not be able to sufficiently verify the origins of the relevant minerals used in our products through the due diligence procedures that we implement, which may harm our reputation. We may also encounter challenges to satisfy those customers who require that all of the components of our products be certified as conflict-free, which could place us at a competitive disadvantage if we are unable to do so.

Any significant change in the regulations described in the paragraphs above could reduce demand for our products or increase our expenses, which in turn could adversely affect our business, financial condition, results of operations and cash flows.

CHANGES IN TAX RATES, TAX LIABILITIES OR TAX ACCOUNTING RULES COULD AFFECT FUTURE RESULTS. As a global company, we are subject to taxation in the United States and various other countries and jurisdictions in which we do business. Significant judgment is required to determine our worldwide tax liabilities. Our future tax rates could be affected by changes in the composition of earnings in countries with differing tax rates, changes in the valuation of our deferred tax assets and liabilities or changes in the tax laws in the jurisdictions in which we do business. In addition, we are subject to regular examination of the income tax returns that we and our subsidiaries file by the Internal Revenue Service and other tax authorities. We regularly assess the likelihood of favorable or unfavorable outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. Although we believe our tax estimates are reasonable, there can be no assurance that any final determination will not be materially different than the treatment reflected in our historical income tax provisions and accruals, which could materially and adversely affect our operating results and financial condition.  

IF WE EXPERIENCE A SIGNIFICANT DISRUPTION IN, OR BREACH IN SECURITY OF, OUR INFORMATION TECHNOLOGY SYSTEMS, OUR BUSINESS MAY BE ADVERSELY AFFECTED.

We rely on information technology systems throughout our Company to manage orders, process shipments to customers, manage inventory levels and maintain financial information. Events could result in the disruption of our systems, including power outages, computer attacks by hackers, viruses, catastrophes, hardware and software failures, and other unforeseen events. If we were to experience a significant period of system disruption in information technology systems that involve our interactions with customers or suppliers, it could result in the loss of sales and customers and significant incremental costs, which could adversely affect our business. In addition, security breaches of our information technology systems could result in the misappropriation or unauthorized disclosure of confidential information belonging to us or to our employees, partners, customers or suppliers, which could result in our suffering significant financial or reputational damage.

* The facility is owned by ROFIN-SINAR Laser GmbH (“RSL”); the real property on which the facility is located is leased by RSL under a 99-year lease.

 ** Includes sales, administration and research and development facilities, where applicable.

*** An aggregate of three facilities. One of the Starnberg main facilities is leased until 2016 from a member of the Company’s Board of Directors. The operating lease was acquired by the Company in 2000, as part of its then acquisition of ROFIN-BAASEL Lasertech GmbH & Co. KG ("RBL"), of which the Board member was a minority shareholder. That lease will terminate by end of December 2016. In January 2015, the Company acquired a new manufacturing facility in Gilching, which is currently under reconstruction and which is intended to replace all RBL leased facilities in Starnberg. During fiscal 2015, the Company also purchased a new manufacturing facility in Kingston upon Hull, which is currently under construction and will afterwards replace the existing leased facility in Kingston upon Hull, acquired one of the Mainz (Germany) main facilities which had previously been leased, and purchased the Overath facility which had previously been leased. The Freiburg facility lease has a renewal option for five

34

years. The Tampere facility lease can be terminated upon six-month notice from the landlord and the lessee. The Gothenburg facility has a renewal option for three years. The Company maintains sales, administration, and research and development facilities at each of the Hamburg, Starnberg, Gunding-Munich, Mainz, Freiburg, Kingston upon Hull, Gothenburg, Tampere, East Granby, Plymouth, Landing, Orlando, Thun, and Nanjing locations. The Company also maintains sales and service offices worldwide, all of which are leased, with the exception of the Pamplona (Spain) and Seoul (South Korea) properties which are owned. The Company believes that its existing facilities are adequate to meet its currently projected needs for the next 12 months and that suitable additional or alternative space would be available, if necessary, in the future on commercially reasonable terms.

ITEM 3. LEGAL PROCEEDINGS The Company has been and is likely to be involved from time to time in litigation involving its intellectual property and ordinary routine litigation arising in the ordinary course of business. A licensor of patents that, before their expiration in 2010, covered the technology used in certain of the Company's CO2 lasers has asserted that the Company has calculated royalties due in respect of certain sales of such CO2 lasers in a manner that is not consistent with the applicable license agreement. In addition, the licensor claims that it has not been provided with copies of invoices and other documentation relating to such sales, to which it asserts it is entitled under the license agreement. The Company disputes these and related allegations and believes that it is in compliance with all of its obligations under the license agreement. The patents, and therefore the license rights, have already expired and there are no further license fees to be calculated and paid. Accordingly, management believes that the resolution of this matter will not have a material adverse impact on the Company's financial condition, results of operations or cash flows.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OVERVIEW ROFIN-SINAR Technologies is a leader in the design, development, engineering, manufacturing and marketing of laser sources and laser-based system solutions for industrial material processing applications, which include primarily cutting, welding and marking a wide range of materials. The Company's product portfolio ranges from single laser-beam sources to highly complex systems, covering all of the key laser technologies such as solid-state, fiber, ultrashort pulse, diode and CO2 lasers and the entire power spectrum, from single-digit watts up to multi-kilowatts, as well as a comprehensive spectrum of wavelengths. An extensive range of laser components completes the product portfolio. Lasers are a non-contact technology for material processing, which have several advantages compared to conventional manufacturing tools that are desirable in industrial applications. The Company's lasers all deliver a high-quality beam at guaranteed power outputs and feature compact designs, high processing speeds, flexibility, low operating and maintenance costs, and easy integration into the customer's production process thus meeting a broad range of its customers' material processing requirements.

According to the Industrial Laser Solutions magazine's 2015 industry forecast published in January 2015, worldwide laser revenues for industrial material processing applications, which are ROFIN’s primary addressed markets, are expected to reach approximately $2.8 billion. The Company has sold more than 75,000 laser sources since 1975 and currently has over 4,000 active customers (including multinational companies with multiple facilities purchasing from the Company). During fiscal 2015, 2014 and 2013, approximately 38%, 40% and 38%, respectively, of the Company’s revenues related to sales of laser products for macro applications, approximately 47%, 47% and 49% respectively, related to sales of laser products for marking and micro applications, and approximately 15%, 13% and 13%, respectively, related to sales of components.

Through its global manufacturing, distribution and service network, the Company provides a comprehensive range of laser sources and laser-based system solutions to the following principal target markets: the machine tool, automotive, semiconductor, electronics, and photovoltaic industries. The Company sells directly to end users and to original equipment manufacturers (“OEMs”) that integrate ROFIN’s laser sources with other system components. Many of ROFIN’s customers are among the largest global participants in their respective industries. During fiscal 2015, 2014, and 2013, 21%, 19% and 20%, respectively, of the Company’s sales were in North America, 45%, 49% and 45%, respectively, were in Europe, and 34%, 32% and 35%, respectively, were in Asia. The results of the fiscal year ended September 30, 2015, were characterized by traditional seasonality in the first half of the year. The second half of the fiscal year 2015 resulted in a recovery of the Asian markets, especially in China. In terms of overall business development, we had a stable business for CO2 laser technology and a far above average growing business with our high-power fiber and ultrashort pulsed laser technologies. For the latter, we experienced especially high interest for our proprietary filament cutting technology of brittle materials. During fiscal year 2015, we were able to significantly improve our profitability, mainly as a result of an optimized cost structure in the manufacture of our high-power fiber lasers, a better fixed cost absorption and positive effects of our efficiency and cost reduction programs.

 Outlook

We continue to target high growth rates in our high-power fiber laser sales in fiscal year 2016. Our 3rd generation high-power fiber laser business is progressing very well as we continue our efforts to further reduce the manufacturing costs of this product. In our second growth area, the ultrashort pulse lasers, we are also gaining momentum. In this segment, we see significant future growth in the medical device, automotive, consumer electronics and photovoltaic industries. With our efficiency and cost reduction programs that we announced in the second quarter of fiscal year 2015, we continue to proactively target further cost control, while actively promoting sales and development in key areas and markets. Coupling these initiatives on the cost side with our strong product portfolio, we feel well-positioned for a successful fiscal year 2016.  Acquisitions and Formation of New Entities Effective August 24, 2011, the Company formed ROFIN BAASEL Laser India Pvt. Ltd. in Mumbai (India) as a wholly-owned subsidiary through its wholly-owned subsidiaries ROFIN-SINAR Laser GmbH (99%) and ROFIN-BAASEL Lasertech GmbH & Co KG (1%). It started its operations in October 2011 and is responsible for sales and service of ROFIN laser products in India.

Fiscal Year 2015 Compared to Fiscal Year 2014  Net Sales – Net sales of $519.6 million represents a decrease of $10.5 million, or 2%, over the prior year. Net sales decreased $20.7 million, or 5%, in Europe/Asia and increased $10.2 million, or 10%, in North America, each as compared to the prior year. The U.S. dollar fluctuated against foreign currencies, which had an unfavorable effect on net sales of $49.3 million. Net sales of laser products for macro applications decreased by 4% to $200.4 million, primarily due to lower business with the machine tool industries which was partially offset by improved business from the automotive industry and advanced applications. Net sales of lasers for marking and micro applications decreased by 3% to $243.1 million compared to fiscal year 2014, mainly due to lower demand for our lasers for micro and marking applications, principally from the electronics, semiconductor and jewelry industries, partially offset by higher demand from the photovoltaic industry. Revenues for the component business increased by 8% to $76.2 million, primarily due to higher sales related to laser diode products and fiber-related components. Gross Profit – The Company’s gross profit of $196.5 million represents an increase of $7.6 million, or 4%, from the prior year. As a percentage of sales, gross profit increased to 38% from 36% in fiscal year 2014. A favorable product and sales mix, the manufacturing cost reduction of our high-power fiber lasers and a better absorption of fixed costs contributed to the improvement in gross margin. Gross profit was unfavorably affected by $9.3 million in fiscal year 2015 due to the fluctuation of the U.S. dollar against foreign currencies. Selling, General and Administrative Expenses – Selling, general and administrative expenses decreased by $8.6 million, or 8%, to $97.4 million, compared to fiscal year 2014. As a percentage of net sales, selling, general and administrative expenses decreased to 19% from 20% in the prior year. Selling, general and administrative expenses were favorably affected by $10.0 million due to the fluctuation of the U.S. dollar against foreign currencies in fiscal year 2015. During fiscal year 2015, SG&A expenses increased due to higher legal and consulting fees as well as expenses related to a change in the Company's senior management. This increase was partially offset by lower marketing, exhibition and other labor costs. Research and Development – The Company’s net expenses for research and development amounted to $40.0 million, which represents a decrease of $5.9 million, or 13%, as compared to the prior fiscal year. Gross research and development expenses for fiscal year 2015 and 2014, were $40.7 million and $47.5 million, respectively, and were reduced by $0.7 million and $1.6 million of government grants during the respective periods. The Company will continue to apply for, and expects to continue receiving, government grants towards research and development, principally in Europe. Research and development expenses were favorably affected by $5.1 million due to the fluctuation of the U.S. dollar against foreign currencies in fiscal year 2015. R&D expenses decreased primarily due to lower material and labor costs, partially offset by lower R&D grants.

Other Income/Expenses – Net other income of $0.9 million in fiscal year 2015 represents a decrease of $1.7 million compared with net other income of $2.6 million in the prior year. This decrease is mainly a result of higher losses related to disposals of fixed assets as well as lower miscellaneous income partially offset by higher net exchange gains and lower net interest expenses.

41

 Income Tax Expense – Income tax expense of $15.7 million in fiscal year 2015 and $11.5 million in fiscal year 2014, represents effective tax rates of 27.6% and 31.4% for the respective periods. The lower effective income tax rate in fiscal year 2015 is primarily a result of the generation of taxable income in countries with lower tax rates and to a $1.9 million favorable effect of the fluctuation of the U.S. dollar against foreign currencies. Net Income Attributable to RSTI – As a result of the foregoing factors, net income attributable to RSTI of $41.3 million ($1.46 per diluted share, based on 28.3 million weighted average common shares outstanding) in fiscal year 2015 increased by $16.1 million over the prior year’s net income attributable to RSTI of $25.2 million ($0.89 per diluted share, based on 28.2 million weighted average common shares outstanding). Net income attributable to RSTI was favorably affected by $7.7 million in fiscal year 2015 due to the fluctuation of the U.S. dollar against foreign currencies.

Fiscal Year 2014 Compared to Fiscal Year 2013  Net Sales – Net sales of $530.1 million represents a decrease of $30.0 million, or 5%, over the prior year. Net sales decreased $17.0 million, or 4%, in Europe/Asia and decreased $12.9 million, or 11%, in North America, each as compared to the prior year. The U.S. dollar fluctuated against foreign currencies, which had a favorable effect on net sales of $8.6 million. Net sales of laser products for macro applications decreased by 2% to $209.6 million, primarily due to lower business with the machine tool industries and advanced application which was partially offset by improved business from the automotive industry. Net sales of lasers for marking and micro applications decreased by 8% to $250.2 million compared to fiscal year 2013. This was mainly due to lower demand for our lasers for micro and marking applications, principally from the electronics and photovoltaic industries, though this was partially offset by higher demand from the semiconductor and jewelry industries.  Revenues for the component business decreased by 4% to $70.3 million, primarily due to lower sales related to laser diode products and fiber-related components. Gross Profit – The Company’s gross profit of $188.9 million represents a decrease of $7.6 million, or 4%, from the prior year. As a percentage of sales, gross profit increased to 36% from 35% in the prior year. The increased percentage margin in fiscal year 2014 was primarily a result of a favorable product mix and the continuing efforts of our manufacturing cost reduction program for high-power fiber lasers. Gross profit was favorably affected by $1.2 million in fiscal year 2014 due to the fluctuation of the U.S. dollar against foreign currencies. Selling, General and Administrative Expenses – Selling, general and administrative expenses increased by $4.3 million, or 4%, to $106.1 million, compared to fiscal year 2013, primarily as a result of one-time expenses associated with the expansion and modernization of production facilities as well as higher consulting fees and an increase in the allowance for bad debts. As a percentage of net sales, selling, general and administrative expenses increased to 20% from 18% in prior year. Selling, general and administrative expenses were unfavorably affected by $1.7 million due to the fluctuation of the U.S. dollar against foreign currencies in fiscal year 2014. Research and Development – The Company’s net expenses for research and development amounted to $45.9 million, which represents an increase of $2.9 million, or 7%, primarily due to a reduction of $0.9 million in R&D grants and higher expenses related to the intellectual property associated with the newly acquired FiLaser technology. Gross research and development expenses for fiscal year 2014 and 2013 were $47.5 million and $45.4 million, respectively, and were reduced by $1.6 million and $2.4 million of government grants during the respective periods. The Company will continue to apply for, and expects to continue receiving, government grants towards research and development, principally in Europe. Research and development expenses were unfavorably affected by $1.1 million due to the fluctuation of the U.S. dollar against foreign currencies in fiscal year 2014.

Other Income/Expense – Net other income of $2.6 million in fiscal year 2014 represents an increase of $2.7 million compared with net other expenses of $0.1 million in the prior year. This increase is a result of $1.0 million due to the partial forgiveness of a loan with the State of Connecticut related to investments and creation of new jobs and net exchange gains of $1.4 million in fiscal year 2014, compared to net exchange losses of $0.5 million in fiscal year 2013, offset by $0.2 million lower net interest income.  Income Tax Expense – Income tax expense of $11.5 million in fiscal year 2014 and $14.1 million in fiscal year 2013, represents effective tax rates of 31.4% and 28.8% for the respective periods. The higher effective income tax rate in fiscal year 2014 is mainly a result of the generation of taxable income in countries with lower tax rates and because the research and development credit legislation has not been re-enacted in the U.S. Income tax expense, a significant portion of which is incurred in foreign currencies, was unfavorably affected by $0.2 million due to the fluctuation of the U.S. dollar against foreign currencies.

42

 Net Income Attributable to RSTI – As a result of the foregoing factors, net income attributable to RSTI of $25.2 million ($0.89 per diluted share, based on 28.2 million weighted average common shares outstanding) in fiscal year 2014 decreased by $9.6 million over the prior year’s net income attributable to RSTI of $34.8 million ($1.22 per diluted share, based on $28.4 million weighted average common shares outstanding). Net income attributable to RSTI was unfavorably affected by $1.8 million in fiscal year 2014 due to the fluctuation of the U.S. dollar against foreign currencies.

LIQUIDITY AND CAPITAL RESOURCES Fiscal Year 2015  The Company’s primary sources of liquidity at September 30, 2015, were cash and cash equivalents of $169.7 million, short-term investments of $5.8 million and short-term credit lines of $63.7 million. As of September 30, 2015, $3.9 million was outstanding under the short-term lines of credit and $2.3 million was used for bank guarantees under these lines of credit, leaving $57.5 million available for borrowing under short-term lines of credit. In addition, the Company maintained credit lines specific to bank guarantees for $12.2 million, of which $4.7 million was used. Therefore, $65.0 million was unused and available under our short-term and bank guarantee lines of credit, in aggregate, at September 30, 2015. At September 30, 2015, the entire amount of our long-term lines of credit was fully drawn. The Company is subject to financial covenants under some of these facilities and lines of credit, which could restrict the Company from drawing money under them. At September 30, 2015, the Company was in compliance with these covenants. Cash and cash equivalents increased by $41.2 million during fiscal year 2015. Approximately $68.6 million in cash and cash equivalents were provided by operating activities, primarily as the result of the net income ($41.2 million), plus other non-cash items, principally depreciation and amortization ($16.2 million) and stock-based compensation expense ($4.2 million), as well as an increase in accrued liabilities and pension obligations ($13.0 million). Operating cash flow was negatively affected mainly by the increase in inventories ($7.4 million). Net cash used in investing activities totaled $26.9 million for the year ended September 30, 2015, and was primarily related to various additions to property and equipment ($34.0 million) and the purchase of short-term investments ($9.3 million), partly offset by the sale of short-term investments ($15.9 million). Net cash provided by financing activities totaled $11.7 million for the year ended September 30, 2015, and was primarily related to proceeds from the borrowings of debt ($34.3 million) and $2.1 million generated through issuance of new shares from the exercise of stock options, partly offset by repayments of loans ($23.4 million), payments of contingent acquisition-related obligations ($0.8 million) and payments to minority shareholders ($0.4 million).

The Company expects that its capital expenditures will be approximately $23 million in fiscal year 2016. Management believes that cash flows from operations, along with existing cash and cash equivalents and availability under the credit facilities and lines of credit, will provide adequate resources to meet the Company’s capital requirements and operational needs on both a current and a long-term basis.

As of September 30, 2015, $133.9 million of the total $175.6 million of cash, cash equivalents and short-term investments, was held by our non-US subsidiaries, with the balance of $41.7 million held by our US subsidiaries. As of that date, of the $23.3 million of the Company's indebtedness to banks, $2.8 million was owed by our US subsidiaries, and $20.5 million was owed by our non-US subsidiaries. We expect our existing domestic cash, cash equivalents and short-term investments, together with cash flows from operations to be sufficient to fund our domestic operating activities. In addition, the US Company has $20.0 million in available and unused lines of credit at September 30, 2015. Therefore, we do not intend, nor do we foresee a need, to repatriate foreign earnings that are considered to be indefinitely reinvested, and we do not believe there are any material implications for or restrictions on the liquidity of our domestic subsidiaries as a result of having a majority of our cash, cash equivalents, and short-term investments held by our foreign subsidiaries.

On November 11, 2015, the Board of Directors authorized the Company to initiate a share buyback program of up to $50 million of the Company's Common Stock over the next eighteen months. The Company expects the purchases to be made from time to time in the open market or in privately negotiated transactions at the Company’s discretion. The Company will utilize existing cash and existing available lines of credit to finance this program.

Fiscal Year 2014  The Company’s primary sources of liquidity at September 30, 2014, were cash and cash equivalents of $128.5 million, short-term investments of $13.1 million, and short-term credit lines of $65.0 million. As of September 30, 2014, $1.6 million was outstanding under the short-term lines of credit and $2.0 million was used for bank guarantees under these lines of credit, leaving $61.4 million available for borrowing under short-term lines of credit. In addition, the Company maintained credit lines specific to bank guarantees for $13.8 million, of which $2.7 million was used. Therefore, $72.5 million was unused and available under our short-term and bank guarantee lines of credit, in aggregate, at September 30, 2014. At September 30, 2014, the entire amount of our long-term lines of credit was fully drawn. The Company is subject to financial covenants under some of these facilities and lines of credit, which could restrict the Company from drawing money under them. At September 30, 2014, the Company was in compliance with these covenants. Cash and cash equivalents increased by $5.2 million during fiscal year 2014. Approximately $35.5 million in cash and cash equivalents were provided by operating activities, primarily as the result of the net income ($25.2 million) plus other non-cash items, principally depreciation and amortization ($17.3 million) and stock-based compensation expense ($4.3 million) and a decrease in other accounts receivable ($2.9 million). Operating cash flow was negatively affected by a decrease in accrued liabilities and pension obligations ($3.9 million) and an increase in trade accounts receivable ($3.6 million). Net cash used in investing activities totaled $24.2 million for the year ended September 30, 2014, and was primarily related to various additions to property and equipment ($10.4 million), the purchase of short-term investments ($38.7 million) and acquisitions ($5.9 million), partially offset by the sale of short-term investments ($30.5 million). Net cash used in financing activities totaled $10.7 million for the year ended September 30, 2014, and was primarily related to payments to minority shareholders ($4.9 million), the stock buyback program ($6.2 million) and repayments of loans ($41.7 million), partly offset by borrowings from banks ($39.7 million) and $2.4 million generated through issuance of new shares from the exercise of stock options. The Company expects that its capital expenditures will be approximately $44 million in fiscal year 2015. Management believes that cash flows from operations, along with existing cash and cash equivalents and availability under the credit facilities and lines of credit, will provide adequate resources to meet the Company’s capital requirements and operational needs on both a current and a long-term basis. As of September 30, 2014, $118.9 million of the total $142 million of cash, cash equivalents, and short-term investments, was held by our non-US subsidiaries, with the balance ($22.8 million) held by our US subsidiaries. As of that date, of the $14.8 million of the Group's indebtedness to banks, $3.0 million was owed by our US subsidiaries, and $11.8 million was owed by our non-US subsidiaries. We expect our existing domestic cash, cash equivalents, and short-term investments, together with cash flows from operations to be sufficient to fund our domestic operating activities. In addition, the US Company has $20.0 million in available and unused lines of credit at September 30, 2014. Therefore, we do not intend, nor do we foresee a need, to repatriate foreign earnings that are considered to be indefinitely reinvested, and we do not believe there are any material implications for or restrictions on the liquidity of our domestic subsidiaries as a result of having a majority of our cash, cash equivalents, and short-term investments held by our foreign subsidiaries.

Fiscal Year 2013  The Company’s primary sources of liquidity at September 30, 2013, were cash and cash equivalents of $133.7 million, short-term investments of $3.2 million, short-term credit lines of $67.0 million. As of September 30, 2013, $2.1 million was outstanding under the short-term lines of credit and $1.5 million was used for bank guarantees under these lines of credit, leaving $63.4 million available for borrowing under short-term lines of credit. In addition, the Company maintained credit lines specific to bank guarantees for $21.2 million, of which $7.7 million was used. Therefore, $76.9 million was unused and available under our short-term and bank guarantee lines of credit, in aggregate, at September 30, 2013. At September 30, 2013, the entire amount of our long-term lines of credit was fully drawn. The Company is subject to financial covenants under some of these facilities and lines of credit, which could restrict the Company from drawing money under them. At September 30, 2013, the Company was in compliance with these covenants. Cash and cash equivalents decreased by $35.0 million during fiscal year 2013. Approximately $57.0 million in cash and cash equivalents were provided by operating activities, primarily as the result of the net income ($35.0 million) plus other non-cash

44

items, principally depreciation and amortization ($15.3 million) and a decrease in inventories ($10.1 million). Operating cash flow was negatively affected by the increase in other accounts receivable ($2.7 million) and by a decrease in accounts payable ($2.2 million) and income tax payable ($1.3 million). Net cash used in investing activities totaled $15.5 million for the year ended September 30, 2013, and was primarily related to various additions to property and equipment ($16.2 million), and purchase of short-term investments ($6.3 million), partially offset by proceeds from the sale of short-term investments ($6.8 million). Net cash used in financing activities totaled $9.4 million for the year ended September 30, 2013, and was primarily related to payments to minority shareholders ($4.3 million), the stock buyback program ($4.1 million) and repayments on loans ($24.9 million), partly offset by borrowings from banks ($20.9 million) and $2.9 million generated through issuance of new shares from the exercise of stock options. The following table illustrates the Company’s contractual obligations as of September 30, 2015:

* Purchase obligations include payments due under various types of agreements to purchase raw materials, services or other goods.

Note – Uncertain tax benefit liabilities of $0.2 million are not included in the Company’s contractual obligation table, as the Company cannot make reasonable estimates about the timing of any required payments related to these liabilities. 

Off-Balance Sheet Arrangements The Company has no off-balance sheet arrangements or financing arrangements involving variable interest entities.

CURRENCY EXCHANGE RATE FLUCTUATIONS Although the Company prepares its consolidated financial statements in U.S. dollars, approximately 67% of its net sales are denominated in other currencies, primarily the Euro, Swedish krona, Swiss francs, British pound, Singapore dollar, Taiwanese dollar, Korean won, Japanese yen, Canadian dollar, Indian rupee and Chinese RMB. Net sales and costs and related assets and liabilities are generally denominated in the functional currencies of the operations, thereby serving to reduce the Company’s exposure to exchange gains and losses. Exchange differences upon translation from each operation’s functional currency to U.S. dollars are accumulated as a separate component of equity. The currency translation adjustment component of shareholders’ equity had the effect of decreasing total equity by $50.9 million at September 30, 2015, and by $7.8 million at September 30, 2014. The fluctuation of the Euro and the other relevant functional currencies against the U.S. dollar has had the effect of increasing or decreasing (as applicable), among other things, the Company's reported net sales, as well as its cost of goods sold, gross profit, selling, general and administrative expenses, research and development expenses and income tax expenses denominated in such foreign currencies when translated into U.S. dollars as compared to prior periods.

 The Company defines the term “constant currency” to mean that financial data for a period are translated into U.S. dollars using the same foreign currency exchange rates that were used to translate financial data for the previously reported period. Changes in sales, gross profit and income from operations include the effect of fluctuations in foreign currency exchange rates. The Company's management reviews and analyzes business results on a constant currency basis and believes these results represent the Company's underlying business trends without distortion due to currency fluctuations. The Company believes that this “constant currency” financial information is a useful measure for investors because it reflects actual changes in operations. The following chart compares our net sales, gross profit and income from operations for each of fiscal years 2015, 2014 and 2013, to the equivalent financial results calculated on a “constant currency” basis. Because this “constant currency” financial information does not conform to Generally Accepted Accounting Principles, it is presented under the caption “Non-GAAP Constant Currency”:

Between fiscal year 2014 and 2015, the average exchange rate for the Euro weakened against the U.S. dollar by approximately 17.8%. The impact of this weakening was to decrease net sales and gross profit by $49.3 million and $9.3 million, respectively, because approximately 67% of fiscal year 2015 sales were denominated in other currencies, primarily the Euro. These exchange rate fluctuations had the effect of decreasing operating expenses by $15.3 million, thereby increasing income from operations by $5.9 million.

Between fiscal year 2013 and 2014, the average exchange rate for the Euro strengthened against the U.S. dollar by approximately 2.9%. The impact of this strengthening was to increase net sales and gross profit by $8.6 million and $1.2 million, respectively, because approximately 69% of fiscal year 2014 sales were denominated in other currencies, primarily the Euro. These exchange rate fluctuations had the effect of increasing operating expenses by $2.9 million, thereby decreasing income from operations by $1.6 million.

Between fiscal year 2012 and 2013, the average exchange rate for the Euro strengthened against the U.S. dollar by approximately 0.6%. The impact of fluctuations in exchanges rates of foreign currencies against the U.S. dollar was to increase net sales by $0.6 million and to decrease gross profit by $0.5 million, because approximately 67% of fiscal year 2013 sales were denominated in other currencies, primarily the Euro. These exchange rate fluctuations had the effect of increasing operating expenses by $0.3 million, thereby decreasing income from operations by $0.8 million.

CRITICAL ACCOUNTING POLICIES The Company’s significant accounting policies are also described in Note 1 of the consolidated financial statements. Certain of the accounting policies require the application of significant judgment by management in selecting appropriate assumptions for calculating financial estimates. By their nature, these judgments are subject to an inherent degree of uncertainty. Allowance for Doubtful Accounts The Company records allowances for uncollectible customer accounts receivable based on historical experience. Additionally, an allowance is made based on an assessment of specific customers’ financial condition and liquidity. If the financial condition of the Company’s customers were to deteriorate, additional allowances may be required. No individual customer represents more than 10% of total accounts receivable. Any increase in allowance will impact operating income during a given period.

46

Inventory Valuation Inventories are stated at the lower of cost or market, after provisions for excess and obsolete inventory salable at prices below cost. Provisions for slow moving and obsolete inventories are provided based on current assessments about historical experience and future product demand and production requirements for the next twelve months. We also write-down up to ninety percent of our total demo inventory costs over thirty six months. These factors are impacted by market conditions, technology changes and changes in strategic direction, and require estimates and management judgment that may include elements that are uncertain. The Company evaluates the adequacy of these provisions quarterly. Although the Company strives to achieve a balance between market demands and risk of inventory excess or obsolescence, it is possible that, should conditions change, additional provisions may be needed. Any changes in provisions will impact operating income during a given period.

Warranty Reserves The Company provides reserves for the estimated costs of product warranties when revenue is recognized. The Company relies upon historical experience, expectations of future conditions, and its service data to estimate its warranty reserve. The Company continuously monitors these data to ensure that the reserve is sufficient. Warranty costs have historically been within our expectations. To the extent we experience increased warranty claim activity or increased costs associated with servicing those claims (such costs may include material, labor and travel costs), revisions to the estimated warranty liability would be required. Increases in reserves will impact operating income during the period.

Pension Obligations The determination of the Company’s obligation and expense for pension is dependent on the selection of certain actuarial assumptions in calculating those amounts. Assumptions are made about interest rates, expected investment return on plan assets, total turnover rates and rates of future compensation increases. In addition, the Company provides the actuarial consultants with subjective factors such as withdrawal rates and mortality rates to develop their calculations of these amounts. The Company generally reviews these assumptions at the beginning of each fiscal year. The Company is required to consider current market conditions, including changes in interest rates, in making these assumptions. The actuarial assumptions that the Company uses may differ materially from actual results due to changing market and economic conditions, higher or lower withdrawal rates, or longer or shorter life spans of participants. These differences may result in a significant impact on the amount of pension benefits expense the Company has recorded or may record.

Another key assumption in determining the net pension expense is the assumed discount rate to be used to discount plan obligations. The Company's U.S. plan uses a cash flow matching approach, which uses projected cash flows matched to spot rates along a high-quality corporate yield curve to determine the present value of cash flows to calculate a single equivalent discount rate. A lower discount rate increases the present value of benefit obligations and increases pension expense. To determine the expected long-term rate of return on plan assets, the Company considers the current and expected asset allocations, as well as historical and expected returns on various categories of plan assets.

Income Taxes We estimate our income tax provision in each of the jurisdictions in which we operate, a process that includes estimating exposures related to examinations by taxing authorities. We must also make judgments regarding the ability to realize the deferred tax assets. The carrying value of our net deferred tax assets is based on our belief that it is more likely than not that we will generate sufficient future taxable income in certain jurisdictions to realize these deferred tax assets. A valuation allowance has been established for deferred tax assets that we do not believe meet the “more likely than not” criteria. We assess whether an uncertain tax position taken or expected to be taken in a tax return meets the threshold for recognition and measurement in the consolidated financial statements. Our judgments regarding future taxable income as well as tax positions taken or expected to be taken in a tax return may change due to changes in market conditions, changes in tax laws, or other factors. If our assumptions and consequently our estimates change in the future, the valuation allowances and/or tax reserves established may be increased or decreased, resulting in a respective increase or decrease in income tax expense.

Share-Based Payment Stock-based compensation cost is measured at grant date, based on the fair value of the award, and is recognized as expense over the employee requisite vesting period. We make judgments about the fair value of the awards, including the expected term of the award, volatility of the underlying stock and estimated forfeitures, which impact the amount of compensation expense

47

recognized in the financial statements. Such amounts may change as a result of additional grants, forfeitures, modifications in assumptions and other factors. The income tax effects of share-based payments are recognized in the financial statements for those awards which will normally result in tax deductions under existing tax law. Under current U.S. federal tax laws, we receive a compensation expense deduction related to stock options only when those options are exercised and vested shares are received. Accordingly, the financial statement recognition of compensation cost for stock options creates a deductible temporary difference which results in a deferred tax asset and a corresponding deferred tax benefit in the statement of operations for all U.S.-based employees. Stock compensation expense related to non-U.S. employees is treated as a permanent difference for income tax purposes.

Recent Accounting Pronouncements Adopted In June 2011, the Financial Accounting Standards Board ("FASB") issued guidance requiring changes to the presentation of comprehensive income which requires entities to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. These changes, with retrospective application, became effective for the Company in fiscal year 2013. Other than the change in presentation to report comprehensive income as a separate but consecutive statement, these changes did not have an impact on the consolidated financial statements. In September 2011, the FASB issued Accounting Standards Update ("ASU") 2011-08, “Testing Goodwill for Impairment”. The amendments under ASU 2011-08 allow entities to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Under these amendments, an entity is not required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than not that the reporting unit’s fair value is less than its carrying amount. The amendments included a number of events and circumstances for entities to consider in conducting the qualitative assessment. Entities now have the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing the first step of the two-step quantitative goodwill impairment test. ASU 2011-08 was effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011 (fiscal year 2013 for the Company). Adoption of ASU 2011-08 did not have a material impact on the Company’s financial statements.

In December 2011, the FASB issued ASU 2011-11, “Disclosures about Offsetting Assets and Liabilities”. ASU 2011-11 amended guidance on balance sheet presentation, to converge the presentation of offsetting assets and liabilities between U.S. GAAP and IFRS. ASU 2011-11 requires that entities disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. In January 2013, the FASB issued ASU 2013-01 which limited the scope of this guidance to derivatives, repurchase type agreements, and securities borrowing and lending transactions. The guidance from these updates became effective for the Company in fiscal year 2014. Adoption of this guidance did not have an impact on the Company's financial statements.

In February 2013, the FASB issued ASU 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income”. ASU 2013-02 requires reclassification adjustments for items that are reclassified from accumulated other comprehensive income to net income be presented on the financial statements or in a note to the financial statements. The new disclosure requirements are effective for fiscal years, and interim periods within those years, beginning after December 15, 2012. As such, ASU 2013-02 became effective October 1, 2013, for the Company and is applied prospectively. The adoption of this updated authoritative guidance resulted in an additional footnote disclosure but had no effect on our financial condition, results of operations or cash flows.

In March 2013, the FASB issued ASU No. 2013-05, “Foreign Currency Matters (Topic 830): Parent’s Accounting for the Cumulative Translation Adjustment upon De-recognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity”. This ASU amended guidance related to a parent company’s accounting for the release of the cumulative translation adjustment into net income upon de-recognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. This guidance became effective for the Company in fiscal year 2015, and is to be applied prospectively to de-recognition events occurring after the effective date. The adoption of this amendment did not have an impact on the Company's financial statements.

In July 2013, the FASB issued ASU No. 2013-11, "Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or Tax Credit Carryforward Exists". ASU 2013-11 provides guidance on financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. Under this guidance an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax

48

loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. These amendments were effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 (fiscal year 2015 for the Company). The adoption did not have an impact on the Company's consolidated financial statements.

Recent Accounting Pronouncements Not Yet Adopted as of September 30, 2015 In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." ASU 2014-09 provides guidance on revenue from contracts with customers, which implements a five step process of how an entity should recognize revenue in order to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This standard was initially released as effective for fiscal years beginning after December 15, 2016. In August 2015, the FASB issued ASU No. 2015-14 which defers the effective date of ASU 2014-09 by one year, with a new effective date for fiscal years beginning after December 15, 2017 (fiscal year 2019 for the Company). The new guidelines can be implemented using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and has not yet determined the method by which it will adopt the standard.

In August 2014, the FASB issued No. ASU 2014-15, "Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern". ASU 2014-15 requires management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in U.S. auditing standards. Specifically, ASU 2014-15 (1) provides a definition of the term substantial doubt, (2) requires an evaluation every reporting period including interim periods, (3) provides principles for considering the mitigating effect of management’s plans, (4) requires certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) requires an express statement and other disclosures when substantial doubt is not alleviated, and (6) requires an assessment for a period of one year after the date that the financial statements are issued (or are available to be issued). The standard will be effective for the first interim period within annual reporting periods beginning after December 15, 2016. Early application is permitted. This guidance will not have a material impact on our consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-05, "Customer's Accounting for Fees Paid in a Cloud Computing Arrangement". ASU 2015-05 provides guidance to customers about whether a cloud computing arrangement includes a software license. If the arrangement includes a software license, the customer should account for the software license element in a manner consistent with the acquisition of other software licenses. If the arrangement does not include a software license, the customer should account for the arrangement as a service contract. This guidance will be effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2015 (fiscal year 2017 for the Company). The Company does not believe the pronouncement will have a material impact on the Company’s consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-03, “Simplifying the Presentation of Debt Issuance Costs”. This standard amends existing guidance to require the presentation of debt issuance cost in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge. It is effective for annual reporting periods beginning after December 15, 2015, but early adoption is permitted. The Company does not believe the pronouncement will have a material impact on the Company’s financial statements and will implement the pronouncement beginning in the period after December 15, 2015.

In July 2015, the FASB issued ASU No. 2015-11, "Simplifying the Measurement of Inventory". The new guidance does not apply to inventory that is measured using last-in, first-out or the retail inventory method. The guidance applies to all other inventory, which includes inventory that is measured using first-in, first-out or average cost and requires that inventory should be measured at the lower of cost and net realizable value. These amendments are effective for fiscal years beginning after December 15, 2016 (fiscal year 2018 for the Company). The Company is currently evaluating the impact of the new guidance on its consolidated financial statements.

Other accounting standards that have been issued by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company's financial statements upon adoption.

ITEM 7A.            QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK The following discussion about the Company’s market risk disclosures involves forward-looking statements. Actual results could differ materially from those projected in the forward-looking statements. The Company is exposed to market risk related to changes in interest rates and foreign currency exchange rates. The Company does not use derivative financial instruments for trading purposes.

 Interest Rate Sensitivity As of September 30, 2015, the Company maintained cash equivalents and short-term investments of $175.6 million, consisting mainly of non-taxable interest bearing securities and demand deposits all with maturities of less than one year. If short-term interest rates were to increase or decrease by 10%, the impact on interest income would be less than $0.1 million. As of September 30, 2015, the Company had $2.6 million of variable rate debt on which the interest rate is reset every six months and $20.7 million of fixed rate debt. Maturities of this debt are as follows: $5.2 million is due in 2016, $5.5 million is due in 2017, $2.5 million is due in 2018, $1.8 million is due annually from 2019 through 2022, $1.6 million is due in 2023 and $1.4 million is due in 2024. A 10% change in the variable interest rates of the Company’s debt would result in an increase or decrease in interest expense of less than $0.1 million. The Company has entered into one interest rate swap agreements to minimize the interest expenses on a portion of its variable debt described in the previous paragraph by shifting from variable to fixed interest rates. The swap agreement is for a total notional amount of Swiss francs 2.5 million (equivalent to $2.6 million based on the exchange rate at September 30, 2015).

 Foreign Currency Exchange Risk The Company enters into foreign currency forward contracts and forward exchange options generally of less than one year duration to hedge a portion of its foreign currency risk on sales transactions. At September 30, 2015, the Company held Japanese yen forward exchange contracts with notional amounts of Euro1.8 million and of $0.3 million. The gains or losses resulting from a 10% change in currency exchange rates would be approximately $0.2 million and $0.3 million, respectively.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

 None.

ITEM 9A.           CONTROLS AND PROCEDURES Attached as exhibits to this Form 10-K are certifications of the Company’s Chief Executive Officer and Chief Financial Officer, which are required in accordance with Rule 13a-14 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). This “Controls and Procedures” section includes information concerning the controls and controls evaluation referred to in the certifications. Part IV, Item 15 of this Form 10-K, sets forth the report of Deloitte & Touche LLP, our independent registered public accounting firm, regarding its audit of the Company’s internal control over financial reporting set forth below in this section. This section should be read in conjunction with the certifications and the Deloitte & Touche LLP report for a more complete understanding of the topics presented. 

Evaluation of Disclosure Controls and Procedures

The Company, under the supervision and with the participation of its management, including the Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of the Company’s disclosure controls and

50

procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act). Based on the evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of September 30, 2015. There has been no change in the Company’s internal control over financial reporting during the fourth quarter of the fiscal year ended September 30, 2015, that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. 

Management Report on Internal Control Over Financial Reporting

The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting to provide reasonable assurance regarding the reliability of the Company’s financial reporting and the preparation of financial statements for external purposes in accordance with Generally Accepted Accounting Principles. Internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records, that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with Generally Accepted Accounting Principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.

Management assessed the Company’s internal control over financial reporting as of September 30, 2015, the end of its fiscal year. Management based its assessment on criteria established in “Internal Control - Integrated Framework” (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Management’s assessment included evaluation of such elements as the design and operating effectiveness of key financial reporting controls, process documentation, accounting policies and the Company’s overall control environment. This assessment is supported by testing and monitoring performed by the Company’s Internal Audit organization. Based on its assessment, management has concluded that the Company’s internal control over financial reporting was effective as of the end of the fiscal year to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with Generally Accepted Accounting Principles. Management reviewed the results of its assessment with the Audit Committee of the Company’s Board of Directors.

The Company’s independent registered public accounting firm, Deloitte & Touche LLP, independently assessed the effectiveness of the Company’s internal control over financial reporting. Deloitte & Touche LLP has issued an attestation report concurring with management’s assessment, which is included at the beginning of Part IV, Item 15 of this Annual Report on Form 10-K.

The Company’s management does not expect that the internal controls over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Due to the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues, errors and instances of fraud, if any, within the Company have been or will be detected.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders ofROFIN-SINAR Technologies Inc. and SubsidiariesPlymouth, Michigan

We have audited the accompanying consolidated balance sheets of ROFIN-SINAR Technologies Inc. and subsidiaries (the "Company") as of September 30, 2015 and 2014, and the related consolidated statements of operations, comprehensive income, stockholders' equity, and cash flows for each of the three years in the period ended September 30, 2015. Our audits also included the financial statement schedule listed in the Index at Item 15 (the “financial statement schedule”). We also have audited the Company's internal control over financial reporting as of September 30, 2015, based on criteria established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on these financial statements and financial statement schedule and an opinion on the Company's internal control over financial reporting based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

ROFIN-SINAR TECHNOLOGIES INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS

September 30, 2015, 2014, and 2013(dollars in thousands, except per share amounts)

1.          SUMMARY OF ACCOUNTING POLICIES Description of the Company and Business The primary business of ROFIN-SINAR Technologies Inc. (“ROFIN” or “RSTI” or “the Company”) is to develop, manufacture, and market industrial lasers and supplies used for material processing applications. The majority of the Company’s customers are in the machine tool, automotive, semiconductor, and electronics industries and are located in the United States, Europe, and Asia/Pacific. For the years ended September 30, 2015, 2014 and 2013, ROFIN generated approximately 58% , 58% and 61% , respectively, of its revenues from the sale of lasers and laser systems. For the years ended September 30, 2015, 2014 and 2013, approximately 42% , 42% and 39%, respectively, of its revenues were generated from sales of after-sales services, replacement parts and components for laser products. 

Principles of Consolidation and Basis of Presentation

The accompanying consolidated financial statements of RSTI and its subsidiaries were prepared in accordance with accounting principles generally accepted in the United State of America ("U.S. GAAP") and include the assets, liabilities, revenues and expenses of all majority-owned subsidiaries over which the Company exercises control and, when applicable, for which the Company has a controlling financial interest or is the primary beneficiary.  All intercompany balances and transactions have been eliminated in consolidation.

Acquisitions and Formation of New Entities The Company uses the acquisition method of accounting for its acquisitions with the respective results of operations included in the consolidated results from the date of acquisition.

• Effective December 23, 2014, the Company acquired an additional 8.8% of the common stock of Nanjing Eastern Laser Company, Ltd. (“NELC”). The company currently holds 88.8% of the share capital of NELC.

 

F-9

The Company also completed the following acquisition of certain assets.

• On April 10, 2014, the Company completed the acquisition of certain assets of FiLaser USA LLC. ("FiLaser") and subsidiaries. The transaction contains all intellectual property including know-how, patents, and patent applications of FiLaser. FiLaser has developed advanced laser process technology used for precision cutting and drilling of brittle material including glass, sapphire and semiconductor substrates. The Company has held back approximately 18% of the purchase price as security for various claims. In addition, the purchase agreement also provides for potential future earn-out payments from revenues generated from certain of these intangible assets.

Fair Value The Company’s cash, short-term investments, accounts receivable and accrued liabilities are carried at amounts that reasonably approximate their fair value due to their short-term nature. The Company’s notes payable are at variable interest rates that approximate market. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models may be applied.

Assets and liabilities recorded at fair value in our balance sheet are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Hierarchical levels are directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities and are as follows:

• Level 1 - Unadjusted observable quoted prices for identical instruments in active markets.

• Level 2 - Observable inputs other than those included in Level 1. For example, quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets.

• Level 3 - Unobservable inputs reflecting management's own assumptions about the inputs used in pricing the asset or liability.

Cash Equivalents Cash equivalents consist of financial instruments that are readily convertible into cash and have original maturities of three months or less at the time of acquisition.

Inventories Inventories are stated at the lower of cost or market, after provisions for excess and obsolete inventory salable at prices below cost. Costs are determined using the first-in, first-out and weighted average cost methods. The Company writes down inventory for estimated obsolescence or unmarketable inventory equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required. We also write-down up to ninety percent of our total demo inventory costs over thirty six months.

Property and Equipment Property and equipment are recorded at cost and depreciated over their estimated useful lives, except for leasehold improvements, which are amortized over the lesser of their estimated useful lives or the term of the lease. The methods of depreciation are straight line for financial reporting purposes and accelerated for income tax purposes. 

F-10

Depreciable lives for financial reporting purposes are as follows:

  Useful LivesBuildings 40 YearsTechnical machinery and equipment 3-10 YearsFurniture and fixtures 3-10 YearsComputers and software 3-4 YearsLeasehold improvements Term of lease

Total depreciation expense for the years ended September 30, 2015, 2014 and 2013, amounted to $13,133, $14,406, and $12,765, respectively.

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.

Goodwill and Other Intangible Assets Goodwill represents the excess purchase price over the fair value of the assets acquired in connection with the Company’s acquisitions. Goodwill is required to be tested on an annual basis for potential impairment at the reporting unit level. A reporting unit is defined as the lowest level of an entity that is a business and that can be distinguished, physically and operationally and for internal reporting purposes, from other activities, operations and assets of the entity. A reporting unit can be no higher than an operating segment and would generally be lower than that level of reporting. The Company manages its business under one operating and reportable segment, and has one reporting unit. In testing for impairment, the fair value of the reporting unit, that is determined based on market data, is compared to its carrying amount. If the carrying value is below the fair value assessment, there will be no impairment loss. If the fair value is below the carrying value, then the Company is required to perform an additional test to determine the implied fair value of the goodwill. The Company performed its annual goodwill impairment testing as of September 30th and determined that the fair value of its reporting unit exceeds its carrying value and accordingly, the second step of the impairment test was not required to be performed.

Revenue Recognition and Accounts Receivable Valuation Revenue is recognized when persuasive evidence of an arrangement exists, the product has been delivered, the price is fixed or determinable and collection is probable. Terms under these arrangements are generally free on board (“FOB”) shipping point, or ex works factory (“EXW”), at which time legal title passes from the Company to the customer. Therefore, delivery is generally considered to have occurred upon shipment. In certain circumstances customers may negotiate different terms. In these situations, delivery is considered to have occurred once legal title has passed from the Company to the customer. This may be at delivery to the customer’s destination or acceptance by the Company’s customer. Sales to end-user customers and resellers typically do not have customer acceptance provisions and only certain of the original equipment manufacturer (“OEM”) customer sales have customer acceptance provisions. Customer acceptance is generally limited to performance under published product specifications. For the few product sales that have customer acceptance provisions because of higher than published specifications, (1) the products are tested and accepted by the customer at a company site or by the customer’s acceptance of the results of a testing program prior to shipment to the customer, or (2) the revenue is deferred until customer acceptance occurs. The Company records revenues net of volume discount rebates that are earned by certain OEM customers, based on sales levels, pursuant to contractual agreements. 

F-11

The vast majority of our sales are made to OEMs resellers, and end users in the industrial market. Sales made to OEMs and resellers in the industrial market do not require installation of the products by the Company, as installation is performed by the customer and are not subject to other post-delivery obligations. The Company may enter into multiple-deliverable arrangements which include the delivery of lasers, laser systems, installation, and training. Revenue from these arrangements is allocated to separate units of accounting if certain criteria are met. The allocation of the arrangement consideration to the separate units of accounting is based on vendor-specific objective evidence or third-party evidence. If such evidence is not available, the Company uses best estimate of selling price. Revenue related to installation and training is recognized when installation is completed or training is provided which usually takes place up to three months after the delivery of the laser or the laser system. The Company records allowances for uncollectible customer accounts receivable based on historical experience. Additionally, an allowance is made based on an assessment of specific customers’ financial condition and liquidity. If the financial condition of the Company’s customers were to deteriorate, additional allowances may be required.

Income and Other Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss tax carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates that apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company recognizes certain tax liabilities for anticipated tax audit findings in the U.S. and other tax jurisdictions based on its estimate of whether, and to the extent to which additional taxes would be due. If the audit finding results in actual taxes owed more or less than what the Company anticipated, its income tax expense would increase or decrease in the period of determination. Revenue and expenses are presented net of any country-specific taxes.

Accounting for Warranties The Company issues a standard warranty of one to two years for parts and labor on lasers that are sold. Additionally, extended warranties are negotiated on a contract-by-contract basis. The Company provides for estimated warranty costs as products are shipped.

The Company’s estimate of costs to fulfill its warranty obligations is based on historical experience and expectation of future conditions. To the extent the Company experiences increased warranty claim activity or increased costs associated with servicing those claims, revisions to the estimated warranty liability would be required.

Foreign Currency Translation The assets and liabilities of the Company’s operations outside the United States are translated into U.S. dollars at exchange rates in effect on the balance sheet date, and revenues and expenses are translated using a weighted average exchange rate during the period. Gains or losses resulting from the translation of foreign currency financial statements are recorded as a separate component of stockholders’ equity. Gains and losses resulting from the re-measurement of foreign currency transactions are reported as a component of “Other expense (income), net”.

Earnings per Share (“EPS”) Basic EPS is computed by dividing “Net Income attributable to RSTI” by the weighted average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution from common stock equivalents (stock options).

F-12

Comprehensive Income Comprehensive income consists of net income, foreign currency translation adjustments, pension liability adjustments and changes in the fair value of interest rate swap agreements, and is presented in the consolidated statements of stockholders’ equity and comprehensive income.

Research and Development Expenses Research and development costs are expensed when incurred and are net of primarily German and other European governments and European Union grants of $691, $1,555 and $2,437, received for the years ended September 30, 2015, 2014 and 2013, respectively. The Company has no future obligations under such grants.

Derivative Financial Instruments The Company uses derivative financial instruments to manage funding costs and exposures arising from fluctuations in interest rates. These derivative financial instruments consist primarily of interest rate swaps. The Company does not use derivative financial instruments for trading purposes. On the date the derivative contract is entered into, the Company designates the derivative as a hedge of the variability of cash flows to be paid related to a recognized liability (“cash flow” hedge). Changes in the fair value of a derivative that is highly effective and that is designated and qualifies as a cash flow hedge are recorded in other comprehensive income, until earnings are affected by the variability in cash flows of the designated hedged item. Interest rate swap agreements designated as hedges of the Company’s financial liabilities are recorded in the consolidated balance sheet at fair value. Adjustments to the fair value of the derivative asset or liability are recorded as an adjustment to other comprehensive income. The swap agreement is for a total notional amount of Swiss francs 2.5 million.

From time to time, the Company enters into foreign currency forward contracts and forward exchange options generally of less than one year duration to hedge a portion of its sales transactions denominated in foreign currencies. The gains and losses from these foreign currency forward contracts and forward exchange options are reflected in the consolidated statement of operations. At September 30, 2015, the Company held Japanese yen forward exchange contracts with notional amounts of Euro 1.8 million and of $0.3 million, respectively.

Operating Leases The Company leases facilities under operating leases. Building lease agreements generally include rent escalation clauses. Most of the Company’s lease agreements include renewal periods at the Company’s option. The Company recognizes scheduled rent increases on a straight-line basis over the lease term beginning with the date the Company takes possession of the leased space.

Use of Estimates Management of the Company makes a number of estimates and assumptions relating to the reporting of assets and liabilities, the disclosure of contingent assets and liabilities and the reporting of revenues and expenses, to prepare these financial statements in conformity with generally accepted U.S. accounting principles. Significant items subject to such estimates and assumptions include the valuation allowance for receivables, inventory valuation, warranty liabilities, the valuation allowance for deferred tax assets, assets and obligations related to employee benefits, and share-based payment awards. Actual results could differ from these estimates.

Stock Incentive Plans The Company measures share-based payments to employees, including grants of employee stock options, at fair value and expenses them in the consolidated statement of operations over the service period (generally the vesting period) of the grant.

F-13

Shipping and Handling Costs The Company accounts for shipping and handling fees and costs by recording revenue from shipping and handling fees in net sales and shipping and handling costs in cost of sales.

Recent Accounting Pronouncements Adopted In June 2011, the Financial Accounting Standards Board ("FASB") issued guidance requiring changes to the presentation of comprehensive income which requires entities to present the total of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. These changes, with retrospective application, became effective for the Company in fiscal year 2013. Other than the change in presentation to report comprehensive income as a separate but consecutive statement, these changes did not have an impact on the consolidated financial statements. In September 2011, the FASB issued Accounting Standards Update ("ASU") 2011-08, “Testing Goodwill for Impairment”. The amendments under ASU 2011-08 allow entities to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Under these amendments, an entity is not required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than not that the reporting unit’s fair value is less than its carrying amount. The amendments included a number of events and circumstances for entities to consider in conducting the qualitative assessment. Entities now have the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing the first step of the two-step quantitative goodwill impairment test. ASU 2011-08 was effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011 (fiscal year 2013 for the Company). Adoption of ASU 2011-08 did not have a material impact on the Company’s financial statements.

In December 2011, the FASB issued ASU 2011-11, “Disclosures about Offsetting Assets and Liabilities”. ASU 2011-11 amended guidance on balance sheet presentation, to converge the presentation of offsetting assets and liabilities between U.S. GAAP and IFRS. ASU 2011-11 requires that entities disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. In January 2013, the FASB issued ASU 2013-01 which limited the scope of this guidance to derivatives, repurchase type agreements, and securities borrowing and lending transactions. The guidance from these updates became effective for the Company in fiscal year 2014. Adoption of this guidance did not have an impact on the Company's financial statements.

In February 2013, the FASB issued ASU 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income”. ASU 2013-02 requires reclassification adjustments for items that are reclassified from accumulated other comprehensive income to net income be presented on the financial statements or in a note to the financial statements. The new disclosure requirements are effective for fiscal years, and interim periods within those years, beginning after December 15, 2012. As such, ASU 2013-02 became effective October 1, 2013, for the Company and is applied prospectively. The adoption of this updated authoritative guidance resulted in an additional footnote disclosure but had no effect on our financial condition, results of operations or cash flows.

In March 2013, the FASB issued ASU No. 2013-05, “Foreign Currency Matters (Topic 830): Parent’s Accounting for the Cumulative Translation Adjustment upon De-recognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity”. This ASU amended guidance related to a parent company’s accounting for the release of the cumulative translation adjustment into net income upon de-recognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. This guidance became effective for the Company in fiscal year 2015, and is to be applied prospectively to de-recognition events occurring after the effective date. The adoption of this amendment did not have an impact on the Company's financial statements.

In July 2013, the FASB issued ASU No. 2013-11, "Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or Tax Credit Carryforward Exists". ASU 2013-11 provides guidance on financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss or a tax credit carryforward exists. Under this guidance an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not

require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. These amendments were effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 (fiscal year 2015 for the Company). The adoption did not have an impact on the Company's consolidated financial statements.

Recent Accounting Pronouncements Not Yet Adopted as of September 30, 2015 In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." ASU 2014-09 provides guidance on revenue from contracts with customers, which implements a five step process of how an entity should recognize revenue in order to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This standard was initially released as effective for fiscal years beginning after December 15, 2016. In August 2015, the FASB issued ASU No. 2015-14 which defers the effective date of ASU 2014-09 by one year, with a new effective date for fiscal years beginning after December 15, 2017 (fiscal year 2019 for the Company). The new guidelines can be implemented using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and has not yet determined the method by which it will adopt the standard.

In August 2014, the FASB issued No. ASU 2014-15, "Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern". ASU 2014-15 requires management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in U.S. auditing standards. Specifically, ASU 2014-15 (1) provides a definition of the term substantial doubt, (2) requires an evaluation every reporting period including interim periods, (3) provides principles for considering the mitigating effect of management’s plans, (4) requires certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) requires an express statement and other disclosures when substantial doubt is not alleviated, and (6) requires an assessment for a period of one year after the date that the financial statements are issued (or are available to be issued). The standard will be effective for the first interim period within annual reporting periods beginning after December 15, 2016. Early application is permitted. This guidance will not have a material impact on our consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-05, "Customer's Accounting for Fees Paid in a Cloud Computing Arrangement". ASU 2015-05 provides guidance to customers about whether a cloud computing arrangement includes a software license. If the arrangement includes a software license, the customer should account for the software license element in a manner consistent with the acquisition of other software licenses. If the arrangement does not include a software license, the customer should account for the arrangement as a service contract. This guidance will be effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2015 (fiscal year 2017 for the Company). The Company does not believe the pronouncement will have a material impact on the Company’s consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-03, “Simplifying the Presentation of Debt Issuance Costs”. This standard amends existing guidance to require the presentation of debt issuance cost in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge. It is effective for annual reporting periods beginning after December 15, 2015, but early adoption is permitted. The Company does not believe the pronouncement will have a material impact on the Company’s financial statements and will implement the pronouncement beginning in the period after December 15, 2015.

In July 2015, the FASB issued ASU No. 2015-11, "Simplifying the Measurement of Inventory". The new guidance does not apply to inventory that is measured using last-in, first-out or the retail inventory method. The guidance applies to all other inventory, which includes inventory that is measured using first-in, first-out or average cost and requires that inventory should be measured at the lower of cost and net realizable value. These amendments are effective for fiscal years beginning after December 15, 2016 (fiscal year 2018 for the Company). The Company is currently evaluating the impact of the new guidance on its consolidated financial statements.

Other accounting standards that have been issued by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company's financial statements upon adoption.

The total deferred income tax assets (liabilities) are included in the accompanying consolidated balance sheet as follows:

Net deferred income tax assets $ 32,128 $ 28,686

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible, as well as limitations imposed by the relevant taxing jurisdictions on the future benefits of those deductions. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, the relevant statutory and regulatory limitations, and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more likely than not that the Company will realize the benefits of these deductible differences. At September 30, 2015, the Company had state net operating tax loss carryforwards available of $35,204 in the United States (which start to expire in 2022). Additionally, the Company had federal net operating tax loss carryforwards available of $11,087 in the United States, $9,122 in Germany and $11,492 in other European/Asian countries (which start to expire in 2017). As of September 30, 2015, deferred tax assets, net of valuation allowances related to these operating tax losses and tax credits, amounted to $9,206.

We have accumulated undistributed earnings of foreign subsidiaries aggregating approximately $430 million at September 30, 2015. These earnings are expected to be indefinitely reinvested outside of the United States. If those earnings were distributed in the form of dividends or otherwise, they would be subject to United States federal income taxes (subject to an adjustment for foreign tax credits), state income taxes and withholding taxes payable to the various foreign countries. It is not currently practicable to estimate the tax liability that might be payable on the repatriation of these foreign earnings.

The Company's policy is to recognize interest and penalties accrued on any unrecognized tax benefits as interest expense and SG&A, respectively. The Company classified the unrecognized tax benefit as non-current because payment is not anticipated within one year of the balance sheet date. As of September 30, 2015, the Company's gross unrecognized tax benefits totaled $239, which includes $5 of interest and penalties. Approximately $234 of unrecognized tax benefits would impact the effective tax rate, if recognized. The Company estimates that the unrecognized tax benefits will not change significantly within the next year. A reconciliation of the beginning and ending amount of gross unrecognized tax benefits, excluding the related accrual for interest, is as follows: 

Balance at September 30, 2012 $ 392Decreases in tax positions for prior years —Increases in tax positions for current years 48Settlements with taxing authorities —

The Company files federal and state income tax returns in several domestic and foreign jurisdictions. In most tax jurisdictions, returns are subject to examination by the relevant tax authorities for a number of years after the returns have been filed. With limited exceptions, the Company is no longer subject to examination by the United States Internal Revenue Service for years through 2009. With respect to state and local tax jurisdictions and countries outside the United States, with limited exceptions, the Company is no longer subject to income tax audits for years before 2009.

11.        EMPLOYEE BENEFIT PLANS The Company has defined benefit pension plans for the RSL and RS Inc. employees. The Company’s U.S. plan began in fiscal year 1995 and is funded. Any new employees hired after January 1, 2007, are not eligible for the RS Inc. pension plan. As is the normal practice with German companies, the German pension plan is unfunded. Any new employees, hired after the acquisition of RBL in 2000, are not eligible for the RSL pension plan. The measurement date of the Company’s pension plans is September 30.

Effective January 1, 2012, the RS Inc. defined benefit pension plan was amended to exclude highly compensated employees, as defined by the Internal Revenue Service, from receiving future years of service under the RS Inc. pension plan. A non-qualified defined benefit pension plan was created to replace the benefits lost by the employees that were otherwise excluded from the qualified pension plan. The determination of the Company’s obligation and expense for pension is dependent on the selection of certain actuarial assumptions in calculating those amounts. Assumptions are made about interest rates, expected investment return on plan assets, total turnover rates, and rates of future compensation increases. In addition, the Company’s actuarial consultants use subjective factors such as withdrawal rates and mortality rates to develop their calculations of these amounts. The Company generally reviews these assumptions at the beginning of each fiscal year. The Company is required to consider current market conditions, including changes in interest rates, in making these assumptions. The actuarial assumptions that the Company uses may differ materially from actual results due to changing market and economic conditions, higher or lower withdrawal rates or longer or shorter life spans of participants. These differences may result in a significant impact on the amount of pension benefits expense the Company has recorded or may record. Another key assumption in determining the net pension expense is the assumed discount rate to be used to discount plan obligations. The Company's U.S. plan uses a cash flow matching approach, which uses projected cash flows matched to spot rates along a high-quality corporate yield curve to determine the present value of cash flows to calculate a single equivalent discount rate. A lower discount rate increases the present value of benefit obligations and increases pension expense.

To determine the expected long-term rate of return on plan assets, the Company considers the current and expected asset allocations, as well as historical and expected returns on various categories of plan assets.

The weighted average assumptions used in the valuation of the plan are as follows: 

  September 30,  2015 2014Discount rate to determine benefit obligations:

United States 4.33% 4.22%Foreign 2.42% 2.40%

Rate of compensation increase    United States 3.0% 3.0%Foreign 3.0% 3.0%

 The Company recognizes the over (under) funded status of the defined benefit plans in the statement of financial position. The Company also recognizes, in other comprehensive income, certain gains and losses that arise during the period but are deferred under current pension accounting rules. A one percent change in the discount rate or the rate of return on plan assets would have a de minimis impact on the projected benefit obligation and the net periodic benefit cost. Expected benefit payments for each of the next five fiscal years and for the five years aggregated thereafter is as follows: $873 in 2016, $888 in 2017, $1,369 in 2018, $1,085 in 2019, $1,162 in 2020 and $8,356 thereafter.

The Company employs a total return investment approach whereby a mix of equity, debt securities and government securities are used to maximize the long-term return of plan assets for a prudent level of risk. The intent of this strategy is to minimize plan expenses by maximizing investment returns within that prudent level of risk. Furthermore, equity investments are diversified across U.S. and non-U.S. stocks as well as growth, value and small and large capitalizations. Additionally, cash balances are maintained at levels adequate to meet near-term plan expenses and benefit payments. Investment risk is measured and monitored on an ongoing basis through semi-annual investment portfolio reviews. Investments in our defined benefit plan are stated at fair value. Level 1 assets are valued using quoted market prices that represent the asset value of the shares held by the trusts. The level 2 assets are investments in pooled funds, which are valued using a model to reflect the valuation of their underlying assets that are publicly traded with observable values. The fair value of our level 3 pension plan assets are measured by compiling the portfolio holdings and independently valuing the securities in those portfolios. The fair values of our pension plan assets, by level within the fair value hierarchy, are as follows:

 19.        STOCK INCENTIVE PLANS The Company maintains a 2007 Incentive Stock Plan, whereby incentive and non-qualified stock options, restricted stock and performance shares may be granted to officers and other key employees to purchase a specified number of common stock at a price not less than the fair market value on the date of grant. The term of the 2007 Incentive Stock Plan continues through 2017. Effective March 12, 2015, the stockholders approved the Rofin-Sinar Technologies Inc. 2015 Incentive Stock Plan to reserve an additional 1,800,000 shares of common stock. There were no incentive stock options, restricted stock or performance shares granted in fiscal years 2015 or 2014 under either plan. Non-qualified stock options were granted to officers and other key employees in fiscal years 2015 and 2014 under the 2007 Incentive Stock Plan. During fiscal year 2015, outside directors each received 3,000 shares of common stock, which were fully vested upon grant. Officers and other key employees received 361,750 shares of non-qualified stock options that vest over five years and will expire not later than ten years after the date on which they were granted. 

F-31

The fair value of our stock options was estimated based on the date of grant using the Black-Scholes option pricing model. The following assumptions were used in these calculations:

DIRECTOR INDEPENDENCE AND CORPORATE GOVERNANCE

Director Independence

We believe that the Company benefits from having a strong and independent Board of Directors. For a director to be considered independent, the Board must determine that the director does not have any direct or indirect material relationship with the Company that would affect his or her exercise of independent judgment. On an annual basis, the Board reviews the independence of all directors under guidelines established by NASDAQ and in light of each director's affiliations with the Company and members of management. This review considers all known relevant facts and circumstances in making an independence determination. Based on this review, the Board has made an affirmative determination that all directors, other than Dr. Wirth, and Messrs. Merk and Baasel, are independent. Mr. Merk was determined to lack independence due to his status as the Company's President and Chief Executive Officer ("CEO"). Dr. Wirth and Mr. Baasel lack independence due to their previously held positions within the Company as noted above in this Item 10 and, in the case of Mr. Baasel due to certain rental payments he receives from the Company as noted below in Item 13 "Certain Relationships and Related Transactions."

Audit Committee Financial Expert

The Board of Directors has determined that Daniel J. Smoke, Chairman of the Audit Committee, qualifies as an "audit committee financial expert" as such term is defined in the applicable Securities and Exchange Commission Audit Committee rules and that he has the requisite level of financial sophistication required under the listing standards of NASDAQ.

Code of Business Conduct and Ethics

The Board of Directors and the Company are committed to good corporate governance practices. The Company's Code of Business Conduct and Ethics requires management, including the Company's CEO, Chief Financial Officer and Controller, and employees to abide by high standards of business conduct and ethics. The Code of Business Conduct and Ethics is available in the Investors Relations section of the Company's web site at www.rofin.com

Executive Sessions of Non-Management Directors

Executive sessions of non-management directors (consisting of all independent directors) are regularly scheduled and held at each meeting of the Board of Directors.

Stockholder Communications with the Board

Any stockholder who wishes to send any communications to the Board, a particular committee of the Board or a particular director should also deliver such communications to the Secretary of the Company at 40984 Concept Drive, Plymouth, MI 48170. The Secretary is responsible for determining, in consultation with other officers of the Company, counsel, and other advisers as appropriate, which stockholder communications will be relayed to the Board.

Risk Oversight Process

Our Board of Directors has the primary responsibility for risk oversight of the Company as a whole. However, the Board has delegated primary oversight responsibility to the Audit Committee. The Audit Committee is responsible for overseeing risks associated with financial and accounting matters, including compliance with all legal and regulatory requirements and internal control over financial reporting. In addition, the Audit Committee has oversight responsibility for the Company's overall business risk management process, which includes the identification, assessment, mitigation and monitoring of key business risks on a company-wide basis. On at least an annual basis the Audit Committee reviews the key business process risks and controls of the Company, and approves the internal audit control testing plan. On a quarterly basis, the internal audit department reports the progress of the annual control testing to the Audit Committee. At the year-end meeting, the Company's internal audit department and the external auditors report their respective findings to the Audit Committee. Any significant findings are followed up on and corrected under the direction of the Audit Committee or Executive Management. The Board believes that the current leadership structure of the Board supports effective oversight of the Company's risk management processes described above by providing independent leadership at the Board committee level, with ultimate oversight by the full Board as led by the Chairman, and the President and CEO.

BOARD OF DIRECTORS AND COMMITTEES

During the fiscal year ended September 30, 2015, the Board of Directors held twenty meetings. All directors attended at least 75% of the meetings of the Board of Directors and meetings of the committees of which they are members. To conduct its business, the Board maintains three standing committees: an Audit Committee, a Compensation Committee, and a Nominating Committee. In addition, from time-to-time, the Board may determine that it is appropriate to form an additional committee or committees of the Board to address a particular matter or matters not specific to, or determined to be appropriate for, one of its standing committees. All committees report on their activities to the Board.

We do not have a formal policy regarding attendance by directors at annual meetings. However, our directors are expected to attend board meetings, our Annual Meeting of Stockholders and meetings of committees on which they serve and to spend the time needed and meet as frequently as necessary to properly discharge their responsibilities. All directors who were on the Board at the time of the last Annual Meeting of Stockholders attended the meeting, with two directors attending remotely by telephone.

The role of Chairman of the Board is currently held by Dr. Peter Wirth, while the role of Chief Executive Officer is held by Thomas Merk. We separate the roles of Chief Executive Officer and Chairman of the Board of Directors in recognition of the differences between the two roles. The Chief Executive Officer is responsible for setting the strategic direction for the Company and the day to day leadership and performance of the Company, while the Chairman of the Board of Directors provides guidance to the Chief Executive Officer and sets the agenda for Board of Directors meetings and presides over meetings of the full Board of Directors and executive sessions of the Board of Directors. Our Chief Executive Officer serves on our Board of Directors, which we believe helps the Chief Executive Officer serve as a bridge between management and the Board of Directors, helping to ensure that both groups act with a common purpose. We believe that the Chief Executive Officer's presence on the Board of Directors enhances his ability to provide insight and direction on important strategic initiatives to both management and the independent directors.

LEAD INDEPENDENT DIRECTOR

The Lead Independent Director is elected annually by the independent members of the Board of Directors and is responsible for coordinating the activities of the independent directors and is expected to perform such other duties and responsibilities as the Board may determine. Mr. Ralph Reins has been elected to serve in the role of Lead Independent Director.

The specific responsibilities of the Lead Independent Director are:

• Act as the principal liaison between the independent directors of the Board and the Chairman of the Board;• Develop the agenda for and preside at executive sessions of the Board's independent directors;• Coordinate with the Chairman of the Board as to an appropriate schedule for Board meetings, seeking to ensure that the independent directors

can perform their duties responsibly, taking into account the cycle of Company operations and activities;• Collaborate with the Chairman of the Board on the agenda for Board meetings and the need for any special meetings of the Board;• Coordinate, as appropriate, with various chairs of Board Committees, the agenda for the respective Board Committee meetings;• Call meetings, as deemed necessary or appropriate, of the independent directors;• Advise the Chairman of the Board as to the quality, quantity and timeliness of the information submitted by the Company's management that

is necessary or appropriate for the independent directors to effectively and responsibly perform their duties, and together with the Chairman of the Board approve all information sent to the Board;

• Recommend to the Board the retention of any advisors and consultants who would report directly to the Board;• Together with the chair of the Nominating Committee, initiate the search for and interview all Board candidates, and make recommendations

to the Nominating Committee;• Recommend to the Nominating Committee, together with the chair of the Committee, the membership of the various Board Committees, as

well as the selection of Committee chairs;• Assist the Board and Company officers in better ensuring compliance with and implementation of the Company's corporate governance

guidelines;• Oversee, together with the chair of the Company's Compensation Committee, the Board's annual assessment of the performance of the Chief

Executive Officer;• Be available to liaise with, and insure consistency in communications to stockholders; and• Perform such other duties as the Board may from time to time delegate.

BOARD COMMITTEES

Audit Committee

The Audit Committee's responsibilities include recommending an independent registered public accounting firm to the Board of Directors, reviewing the proposed scope of such audit, approving the audit fees, overseeing and evaluating the performance of the independent registered public accounting firm, overseeing the accounting and financial reporting policies and internal control systems of the Company, reviewing and approving transactions between the Company and its directors, officers and affiliates, considering whether the provision by the external auditors of services related to the annual audit and quarterly reviews is consistent with maintaining the auditors' independence, and reviewing annually the adequacy of the Audit Committee Charter. The Board of Directors has adopted a written Charter for the Audit Committee. A copy of the Audit Committee Charter is available in the Investor Relations section of the Company's website at www.rofin.com.

During fiscal year 2015, the members of the Audit Committee were Messrs. Reins, Smoke and Willis and Dr. Fantone. Mr. Smoke has been identified as an "audit committee financial expert" under applicable Securities and Exchange Commission ("SEC") audit committee rules. All members of the Audit Committee are independent directors within the meaning of Rule 5605(a)(2)of the NASDAQ Marketplace Rules. During fiscal year 2015, Mr. Smoke was Chairman of the Audit Committee. In fiscal year 2015, the Audit Committee held four meetings.

The Nominating Committee

The Nominating Committee is responsible for assisting the Board by actively identifying individuals qualified to become Board members and recommending to the Board of Directors nominees for election at the next annual meeting of stockholders. The Nominating Committee has two primary methods for identifying candidates (other than those proposed by the Company's stockholders, as discussed below). First, on a periodic basis, the Nominating Committee solicits ideas for possible candidates from a number of sources including members of the Board; senior level Company executives; individuals personally known to the members of the Board; and research. Second, the Nominating Committee may from time to time use its authority under its charter to retain, at the Company's expense, one or more search firms to identify candidates (and to approve such firms' fees and other retention terms). The Nominating Committee will also consider nominees recommended by stockholders. Stockholders wishing to submit nominations should notify the Company at its principal offices (Attention: Cindy Denis, Secretary, 40984 Concept Drive, Plymouth, MI 48170) of their intent to do so. To be considered by the Nominating Committee, nominations must be received on or before the deadline for receipt of stockholder proposals. Any candidate submitted by a stockholder must meet the definition of an "independent director" under NASDAQ rules.

The Nominating Committee will consider all candidates identified through the processes described above, and will evaluate each of them, including incumbents, based on the same criteria. Once the nominee has been contacted and accepts to be considered as a nominee, the Nominating Committee reviews and analyzes the nominee's resume, credentials, qualifications and characteristics to serve on the Board, and the expertise the nominee would offer the Board of Directors and the Company. While the Nominating Committee does not have a formal policy with respect to diversity, the Board and the Committee believe that it is essential that Board members represent diverse business backgrounds, experience, talents, and perspectives. In considering candidates for the Board, the Nominating Committee considers the entirety of each candidate's credentials. Director nominees are selected based on, among other things, their ability to represent the best interests of the Company's stockholders and not just one particular constituency; demonstrated sound business judgment and an inquiring mind; expertise that adds to the composition of the Board; professional experience, education, and their interest in, and capacity for understanding the complexities of, the operation of the Company; personal and professional character and actions appropriate for a Board member and the reputation of the Company; and their being prepared to participate fully in Board activities, including active membership on at least one Board committee and attendance at, and active participation in, meetings of the Board and the committee of which he or she is a member. These individuals can bring considerable experience to the impartial oversight of the Company's operations. The Board of Directors has adopted a written Charter for the Nominating Committee. A copy of the Nominating Committee Charter is available in the Investor Relations section of the Company's website at www.rofin.com.

The members of the Nominating Committee, during fiscal year 2015, were Dr. Fantone and Messrs. Reins, Smoke and Willis, each of whom is an independent director within the meaning of Rule 5605(a)(2) of the NASDAQ Marketplace Rules. Messrs. Reins, Willis, and Smoke and Dr. Fantone are not employees of the Company. During fiscal year 2015, Dr. Fantone was Chairman of the Nominating Committee. In fiscal year 2015, the Nominating Committee held nine meetings.

The Compensation Committee

The Compensation Committee is responsible for providing a general review of the Company's compensation and benefit plans and ensuring that they meet financial and strategic objectives.

The responsibilities of the Compensation Committee also include administering the Annual Incentive Plan and the 2007 Incentive Stock Plan and 2015 Incentive Stock Plan (all of which are described below), including selecting the officers and salaried employees to whom awards will be granted and making such awards. The Board of Directors has adopted a written charter for the Compensation Committee. A copy of the Compensation Committee Charter is available in the Investor Relations section of the Company's website at www.rofin.com. The members of the Compensation Committee are Messrs. Reins, Willis, and Smoke and Dr. Fantone, each of whom is an independent director within the meaning of Exchange Act Rule 10C-1(b)(1) and Rules 5605(a)(2) and 5605(d)(2) of the NASDAQ Marketplace Rules. During fiscal year 2015, Mr. Willis was Chairman of the Compensation Committee. In fiscal year 2015, the Compensation Committee held ten meetings.

Compensation Committee Matters

Scope of Authority

The Compensation Committee acts on behalf of the Board of Directors of the Company and, by extension, the stockholders to establish the compensation of executive officers of the Company and provides oversight of the Company's global compensation philosophy. The Compensation Committee also acts as the oversight committee with respect to our 2015 Incentive Stock Plan (including all amendments to the Plan) discussed below covering Named Executive Officers ("NEOs") and other employees. In general, the Committee may rely on recommendations from the Chief Executive Officer regarding participant selection and award determination. However, the Compensation Committee makes final determinations regarding any compensation decisions.

The Compensation Committee has the sole discretion to retain or obtain the advice of a compensation consultant, legal counsel or other adviser (each a "Compensation Adviser"), and the direct responsibility for the appointment, compensation and oversight of the work of any Compensation Adviser it retains. Additionally, the Compensation Committee's charter requires the Committee to take into account the following six factors before hiring any Compensation Adviser:

The Committee's Processes

The Compensation Committee has established a number of processes to assist it in ensuring that the Company's executive compensation program is achieving its objectives. Among those are:

• the provision of other services to the Company or its subsidiaries by the person that employs the Compensation Adviser;• the amount of fees received from the Company or its subsidiaries by the person that employs the Compensation Adviser, as a percentage of

the total revenue of the person that employs the Compensation Adviser;• the policies and procedures of the person that employs the Compensation Adviser that are designed to prevent conflicts of interest;• any business or personal relationship of the Compensation Adviser with a member of the Committee;• any stock of the Company owned by the Compensation Adviser; and• any business or personal relationship of the Compensation Adviser or the person employing the Compensation Adviser with an executive

officer of the Company.

• Meetings. The Compensation Committee meets several times each year. Compensation Committee agendas are established in consultation with the Committee Chair. The Compensation Committee also meets in executive session following regular meetings, as deemed appropriate.

• Assessment of Company Performance. The Compensation Committee uses Company performance measures in establishing total compensation ranges. The Compensation Committee considers various measures of Company performance, including revenues or net income.

• Assessment of Individual Performance. Individual performance has a strong impact on the compensation of employees, including the NEOs. During the course of each year, the Compensation Committee meets with the Chief Executive Officer to review recommendations on changes, if any, in base salary of each NEO (other than the Chief Executive Officer).

Compensation Committee Interlocks And Insider Participation

Messrs. Willis, Reins and Smoke and Dr. Fantone are the members of the Compensation Committee of the Board of Directors of the Company. None of such individuals is an officer of the Company. There are no compensation committee interlocks involving executive officers of the Company.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires the Company's officers and directors, and persons who own more

than ten percent of a registered class of the Company's equity securities, to file reports of securities ownership and changes in such ownership with the Securities and Exchange Commission (the "SEC"). Officers, directors and greater than ten percent stockholders are also required by rules promulgated by the SEC to furnish the Company with copies of all Section 16(a) forms they file.

Based solely upon a review of the copies of such forms, the absence of a Form 3, Form 4 or Form 5 or written representations that no Form 4's

or 5's were required, the Company believes that, with respect to the fiscal year ended September 30, 2015, its officers, directors and greater than ten percent beneficial owners complied with all applicable Section 16(a) filing requirements.

Item 11. EXECUTIVE COMPENSATION

COMPENSATION DISCUSSION AND ANALYSIS

For the fiscal year ended September 30, 2015, which we refer to as "fiscal year 2015", our NEOs were:

Following this "Compensation Discussion and Analysis", you will find a series of tables containing specific information about the compensation earned, awarded or paid during fiscal year 2015. Please refer to those tables when considering the discussion below.

Executive Summary

In determining fiscal year 2015 compensation for our senior executives, the Compensation Committee of the Board, comprised solely of independent directors, considered the operating plans and targets established by management for the fiscal year, the actual performance of the Company during that period, and the external market conditions of the Company's served markets. The Compensation Committee seeks to compensate our NEOs (and other key employees) in a way that would enable us to retain them as our senior management team through the challenges and appropriately recognize their individual contributions to the Company performance, consistent with our overall business objectives and our stockholders' best interests.

• Stockholder Advisory Votes. The Committee considers the results of the most recent advisory vote of the stockholders on executive compensation in making compensation determinations and recommendations. However, the Committee is not bound by the results of an advisory vote.

• Consideration of Compensation Arrangements and their Relationship to the Encouragement of Risk-Taking Behavior. The Committee reviews the Company's incentive compensation arrangements to determine whether they encourage excessive risk-taking. The Committees reviews and discusses at least annually the relationships between risk management policies and practices and compensation, and evaluates compensation policies and practices that could mitigate any such risk.

• Mr. Thomas Merk, our President and Chief Executive Officer, effective July 1, 2015

• Mr. Gunther Braun, our former President and Chief Executive Officer, who was succeeded by Mr. Merk effective July 1, 2015

• Ms. Ingrid Mittelstaedt, our Chief Financial Officer and Executive Vice President of Finance and Administration

• Mr. Louis Molnar, our Chief Operating Officer - North America Business

• Dr. Ulrich Hefter, our Chief Technical Officer

• Mr. Martin Seifert, our Chief Operating Officer - Defense Business

In March 2015, we held a stockholder advisory vote on the compensation of our named executive officers, commonly referred to as a say-on-pay vote. Our stockholders approved the compensation of our named executive officers, with approximately 94% of stockholder votes cast in favor of our 2015 say-on-pay resolution. As we evaluated our compensation practices and talent needs throughout 2015, we were mindful of the strong support our stockholders expressed for our pay for performance compensation philosophy. As a result, the Committee decided to retain our general approach to executive compensation, with an emphasis on short- and long-term incentive compensation that rewards our most senior executives when they deliver value for our stockholders. In addition, when determining how often to hold a stockholder advisory vote on executive compensation, the Board took into account the strong preference for an annual vote expressed by our stockholders at our 2011 Annual Meeting. Accordingly, the Board determined that we will hold an annual advisory stockholder vote on the compensation of our named executive officers until the next say-on-pay frequency vote.

In making its compensation decisions for fiscal year 2015, the Compensation Committee paid particular attention to the following areas of achievement:

The Compensation Committee also took into account the following threshold, target, and maximum level metrics and the performance of the Company as compared to these metrics:

Consistent with our historical compensation practices, our fiscal year 2015 compensation program featured the following attributes:

Compensation Philosophy and Objectives

Our philosophy is to align NEO compensation with our strategic objectives, while providing competitive compensation that enables us to attract and retain top quality executive talent. To that end, the primary objectives of our NEO compensation policy are to:

• Market share gains in the fiber and ultra-short pulse laser markets;• Cost reduction achievement in fiber lasers; and• Company-wide initiatives to increase productivity and reduce expenses.

• Sales: Sales targets were weighted at 30% for the Incentive Plan with the sales target threshold being set at $540 million and maximum set at $600 million. If the Company achieved its target (set at $560 million), the potential payout would be 100%, if the Company achieved its stretch goal (set at $580 million), the potential payout would be 110%, and if the Company achieved its maximum (set at $600 million), the potential payout would be up to 150% of the incentive sales target. The actual net sales for fiscal year 2015 were approximately $519.6 million, a decrease of approximately 2% over fiscal year 2014.

• Net Income Improvement: Net income targets were weighted at 70% for the Incentive Plan. The 2015 net income threshold was set at $40 million, and the net income maximum was set at $57 million. If the Company achieved its target (set at $44.9 million), the potential payout would be 100%, if the Company achieved its stretch goal (set at $50 million), the potential payout would be 110%, and if the Company achieved its maximum (set at $57 million), the potential payout would be up to 150% of the incentive sales target. The actual net income for fiscal year 2015 was $41.3 million, an increase of approximately 64% over fiscal year 2015.

• A balanced mix of annual cash and long-term equity incentives that reward our NEOs for current performance and align their compensation with longer term performance and shareholder value creation.

• No NEO severance plans or agreements, and no "golden parachute" agreements with cash payouts for the NEOs conditioned upon a change of control.

• A structure for NEO compensation that attempts to comply with Internal Revenue Code requirements to tax deductibility.

• Option plan awards were also allocated, pursuant to our option plan, by the Compensation Committee. These awards were principally based on the performance of the NEO and certain other key employees since the Compensation Committee determined that these individuals were instrumental in achieving the Company's performance in fiscal year 2015.

• Provide compensation in a manner that allows for management to share in the risks and potential rewards of our enterprise growth.

• Maintain the common interest of NEOs and our stockholders in our long-term growth through a focus on stock options.

Principal Components of Executive Compensation

The principal components of our executive compensation program are:

Mix of Compensation Components

NEO compensation is based on our pay-for-performance philosophy, which rewards executive performance that correlates closely with the achievement of both shorter-term performance objectives and longer-term shareholder value. To this end, a substantial portion of our executives' annual and long-term compensation is at-risk, meaning that the ultimate value of their compensation is largely or entirely dependent on our overall growth and success, thereby aligning their interests with those of our stockholders. We believe that this benefits our Company and stockholders by ensuring that our management team has strong commitment to the health of our entire Company.

Target Pay Philosophy - How We Use Our "Comparator Group"

Our NEO compensation is reviewed against executive compensation at a designated set of publicly-traded companies (which we call our "Comparator Group"). Historically, our Comparator Group was constructed using companies that are reasonably similar to us in terms of their total revenues, manufacturing focus and profitability and for which executive officer positions were comparable to ours in terms of breadth, complexity and scope of responsibilities.

Historically, our Comparator Group included manufacturing companies with an optical, electronics and/or engineering focus having revenues ranging from $400 million to approximately $1.0 billion with return on sales of approximately 10% or higher over a three-year period. The latest NEO compensation comparative analysis was completed in December 2011. Consistent with the approximate historical practice, it is expected that the next NEO compensation comparative analysis will occur in 2016.

In December 2011, the Company hired Radford, an independent third party compensation consulting firm, to assist with the NEO compensation analysis. Radford provided an analysis of data from peer companies' proxy filings with respect to similarly situated individuals at a Comparator Group of companies and compensation survey sources. The Comparator Group in this analysis included manufacturing companies with a semiconductor and/or capital equipment background having revenues ranging from approximately $200 million to approximately $1.6 billion. The Comparator Group consisted of the following companies: Coherent Inc., Newport Corp., GSI Group, FLIR Systems, Inc., Aeroflex Inc., MTS Systems, Inc., Littlefuse Inc., Altra Holdings Inc., Blount International, Cymer, Electro Scientific Industries, FEI Company, Finisar, II-VI Inc., IPG Photonics, Measurement Specialties, MKS Instruments, NN Inc., and Veeco Instruments. This Comparator Group is consistent with the Comparator Group used in the 2007 NEO compensation analysis. The results of this third party study have shown that the Company's NEO total compensation is positioned at the 50th percentile of the Comparator Group. This report supports the Company's NEO compensation packages in comparison to the Comparator Group.

The Compensation Committee retained Radford in November 2012 to provide an update to the executive compensation review conducted in December 2011. This update was intended to present the Compensation Committee with the appropriate facts and data to make decisions regarding executive compensation.

The Compensation Committee retained Radford in fiscal year 2015 to advise the Committee on the appropriate compensation as the Company transitioned to a new Chief Executive Officer, including change of control benefits for Mr. Merk and other NEOs.

The Compensation Committee evaluates the total compensation package of our NEOs against the total compensation package of NEOs in the Comparator Group. The individual components of the total package and the relative size of each component to the total compensation package are used in this consideration, although the Committee does not seek to match any particular percentile among the Comparator Group. Instead, the Committee considers information on our Comparator Group in order to get a general sense of

• Provide incentives for short-term success-oriented operation through our annual cash incentive program.

• Attract and retain individuals with the leadership and technical skills to carry the Company into the future and to grow the business and create long-term shareholder value for our stockholders.

• Base salary

• Annual cash incentive plan; and

• Long-term, equity-based incentives

- 11 -

compensation trends in our industry and the appropriateness of our NEO compensation packages. The Compensation Committee relies on proxy statements, executive compensation surveys and other published information for data on current market pay practices and trends.

Components of Executive Compensation for fiscal year 2015

As is our general philosophy, for fiscal year 2015, the Compensation Committee used a three-pronged approach to our executive compensation program: 1) base salary; 2) annual cash incentive plans; and 3) long-term equity-based compensation. We believe that this program balances the mix of cash and equity compensation, and leaves an appropriate portion of each NEOs compensation package "at-risk". Historically, executive compensation for a particular fiscal year is reviewed and finalized by the Compensation Committee during its first meeting in the then current fiscal year.

Base Salary

The Compensation Committee considers relevant market pay practices when setting executive compensation to ensure our ability to recruit and retain high caliber talent. The Compensation Committee sets base salary levels for executive officers each year based on a number of factors, including the status of the competitive marketplace for such positions, the responsibilities of the position, the experience of the individual, the individual's performance and contributions to the Company during the past year, and our desire to maintain internal equity in pay structure in relationship to other executives within the Company and against the executive compensation of our Comparator Group. Base salary is the one fixed component of our executives' total direct compensation, in contrast to incentive compensation, which is based on our performance. The Compensation Committee reviews the base salaries of executive officers annually and whenever an executive is promoted. The Compensation Committee meets with the Chief Executive Officer to review recommendations on changes, if any, in base salary of each NEO (other than the Chief Executive Officer).

The Compensation Committee reviews and approves changes in the base salary of the Chief Executive Officer. Our NEOs' base salaries trend towards the low end of the range of base salaries in our Comparator Group for that position.

For more information regarding our NEOs' base salaries for fiscal year 2015, see the "Summary Compensation Table" appearing below in this Annual Report.

Cash Incentive Plan

The Compensation Committee has established a Cash Incentive Plan for our NEOs in order to align executive compensation with the Company's revenue, operating profit and net income objectives.

Under the Cash Incentive Plan, actual bonus payouts are determined by the Compensation Committee based upon the actual performance of the NEO against the targeted goals. The Chief Executive Officer approves all individual awards under the Cash Incentive Plan except his own and the NEOs', which are approved by the Compensation Committee in its sole discretion. The Cash Incentive Plan is available to all NEOs and selected other members of the Company's senior management. Awards to the NEOs under the Cash Incentive Plan paid for fiscal year 2015 appear in the Summary Compensation Table under the "Non-Equity Incentive Plan Compensation" column. The selected participants receive incentive awards designed to focus management's attention and effort on the attainment of pre-established annual performance goals.

Target Opportunities. Each participant in the Cash Incentive Plan is assigned a target award opportunity, expressed as a percentage of the annual base salary. For fiscal years 2015 and 2014, the target award opportunity for Mr. Braun was 70% of his base salary, the target award opportunities for Messrs. Hefter, Merk, Molnar and Ms. Mittelstaedt were 50% of their base salaries, and the target award opportunity for Mr. Seifert was 40% of his base salary. After becoming the Company's Chief Executive Officer effective July 1, 2015, Mr. Merk's target award opportunity was raised to 70% of his base salary for the proportionate remaining three months of fiscal year 2015.

Pre-Established Performance Goals. For Messrs. Merk, Hefter, Molnar and Seifert, and Ms. Mittelstaedt, the performance goals are based upon consolidated revenues and consolidated net income for the fiscal year. In addition, Messrs. Molnar's and Seifert's performance goals include pre-established individual goals which are determined to be important in relationship to the position they maintain within the Company.

For each metric, a specific target performance goal and a defined performance range around the target are established. The performance range consists of a threshold, minimum performance level, and a maximum performance level for each NEO. The cash incentive award is guaranteed if the applicable targets are reached. Details of these metrics are included in the Executive Summary appearing earlier in this Compensation Discussion and Analysis.

- 12 -

For fiscal year 2015, if we reached our threshold targets, Mr. Braun would have been entitled to 35% of his base salary; Messrs. Hefter, Merk and Molnar, Ms. Mittelstaedt would have been entitled to 25% of their base salaries, and Mr. Seifert would have been entitled to 20% of his base salary. If we reached our target goals, Mr. Braun would have been entitled to 70% of his base salary; Messrs. Hefter, Merk and Molnar, and Ms. Mittelstaedt would have been entitled to 50% of their base salaries, and Mr. Seifert would have been entitled to 40% of his base salary. If we reached the stretch performance target, Mr. Braun would have been entitled to 77% of his base salary; Messrs. Hefter, Merk and Molnar and Ms. Mittelstaedt would have been entitled to 55% of their base salary, and Mr. Seifert would have been entitled to 44% of his base salary. If we reached the maximum performance target, Mr. Braun would have been entitled to 105% of his base salary; Messrs. Hefter, Merk and Molnar and Ms. Mittelstaedt would have been entitled to 75% of their base salaries. Subsequent to becoming the Company's Chief Executive Officer, the percentages for Mr. Merk were increased to those previously assigned for Mr. Braun, for the proportionate part of the 2015 fiscal year during which Mr. Merk was CEO.

In fiscal year 2015, the Compensation Committee also included six-month performance goals, that if achieved, could add an additional 20% to the above targets.

The Compensation Committee does have "negative" discretion to reduce the size of any award if the relevant targets are met. Additionally, the Compensation Committee has the discretion to provide an award given the overall performance of the Company if specific target goals are not met.

Our target goals are intended to be attainable yet challenging. However, they are set high enough that significantly exceeding them would require performance in excess of our expectations. We believe that if financial targets are not attainable, the Cash Incentive Plan will lose the motivational effect it was designed to achieve and payouts will lag behind competitive market levels.

Long-Term Incentive Compensation - Stock Options

We believe that long-term equity incentive compensation is an integral component of our compensation program because it has the effect of recruiting, retaining and motivating high-quality employees. In addition, we believe that long-term incentive compensation aligns executives' interests with the interests of stockholders, and rewards the achievement of the Company's long-term strategic goals. Grants of long-term incentive awards are based on Company performance, and targeted at levels that approximate market value of equity incentive compensation for executives holding comparable positions at companies in the Comparator Group, utilizing the same compensation data used for setting total annual compensation. In November of each fiscal year, the Compensation Committee reviews and approves the long-term incentive compensation to be granted to executives and other eligible employees who participate in the Company's long-term incentive programs. Generally, in recent years, stock options have been granted to executive officers as a compensation component over the vesting period of the options, generally five years.

All equity awards granted in fiscal year 2015 were granted from our 2007 Incentive Stock Plan and 2015 Incentive Stock Plan. Some features of our stock option program include:

For additional information concerning the timing of grants of stock options, see "Equity Grant Practices" below.

In November 2014, the Committee awarded stock options from our 2007 Incentive Stock Plan to each of the NEOs as follows: Mr. Braun 40,000 shares; Mr. Merk and Ms. Mittelstaedt 30,000 shares; Mr. Molnar 25,000 shares; Mr. Hefter 20,000 shares; and Mr. Seifert 5,000 shares. In July 2015, the Committee awarded Mr. Merk an additional 20,000 shares from our 2015 Incentive Stock Plan upon being named as President and Chief Executive Officer of the Company. We determined the size of each NEO's grant based on our previous year's performance and the relative performance of each NEO and his or her seniority and responsibilities. In addition, the Committee considered the historical equity compensation awards by companies in our Comparator Group.

Although the Compensation Committee has the authority under our 2007 Incentive Stock Plan and our 2015 Incentive Stock Plan to grant stock appreciation rights, stock grants, and stock units in addition to stock options, in recent years we have used only stock options because we believe that options provide NEOs the best opportunity to purchase and maintain an equity position in the Company and to share in the appreciation of the value of our Common Stock. However, we may grant other forms of equity

• Options vest ratably over 5 years, which means that twenty percent (20%) of the options will become exercisable one year from the date of grant, and an additional 20% of the option will become exercisable each year thereafter;

• The term of each grant does not exceed ten (10) years; and

• The exercise price is equal to the closing market price on the date of grant.

- 13 -

compensation in the future. We do not currently have any stock ownership guidelines or requirements in place for our executive officers; however, we have designed our equity incentive compensation to encourage stock ownership by management.

Equity Grant Practices

Historically, the Company has issued stock options primarily in one of three situations: (1) to employees periodically as an incentive for continued, productive employment and retention; (2) to new employees as a component of an offer of employment and an incentive to attract them to the Company and (3) to new employees in connection with an acquisition as an incentive for continued productive employment with the Company after theacquisition is complete. All stock options are issued with an exercise price equal to the closing market value of a share of our Common Stock on the date of grant.

Stock options are granted, at the discretion of the Compensation Committee, to groups of employees from time to time at a regularly scheduled meeting of the Compensation Committee. The exact amount of these grants to NEOs in 2015 is shown in the "Grants of Plan Based Awards" table appearing below in this Annual Report. The Compensation Committee approves all grants to employees and no authority to make grants has been delegated to management. Stock options may be granted to new employees as a component of their overall compensation package. These option grants are approved by the Compensation Committee.

The Company may also issue options as a component of an acquisition. When this occurs, the options are approved by the Compensation Committee at a special meeting or as part of a regular meeting. No such options were issued during fiscal year 2015.

Long-Term Incentive Compensation-Pension Plans

RSL Pension Plan

Mr. Hefter and Ms. Mittelstaedt participate in the Rofin-Sinar Laser GmbH Pension Plan (the "RSL Pension Plan") for RSL executives, an unfunded plan in accordance with the typical practices of German companies. The RSL Pension Plan provides pensions to participants who (i) retire on or after age 60 or terminate employment due to a permanent disability and (ii) have served at least 10 years with RSL at the time of separation.

The annual benefits payable under the RSL Pension Plan, which commence at the statutory retirement age of 65 for Mr. Hefter and 67 for Ms. Mittelstaedt (according to German law), are based upon the age at which the participant leaves RSL.

Book reserves are kept to record benefits accruals under the RSL Pension Plan. Mr. Hefter and Ms. Mittelstaedt joined or were deemed to have joined (as applicable) the RSL Pension Plan on October 1, 1984 and January 1, 1997, respectively. Assuming retirement at or after age 60, Mr. Hefter and Ms. Mittelstaedt would receive a monthly pension benefit of $997 and $666, respectively (at the weighted average Euro/U.S. dollar exchange rate in effect during the fiscal year ended September 30, 2015).

Rofin-Sinar Inc. Pension Plan

In 1996 we adopted a defined benefit plan for employees of Rofin-Sinar Inc. known as the Rofin-Sinar Inc. Pension Plan (the "RSI Plan"). Under the RSI Plan, employees receive annual pension benefits equal to the product of (i) the sum of 1.125% of the first $12,000 of "average final compensation" and 1.5% of "average final compensation" in excess of that amount, and (ii) the number of years of service in which the employee was employed by a participating employer. Average final compensation is based upon the period of four consecutive plan years out of the last ten full plan years preceding the employee's retirement which produces the highest amount. Mr. Molnar is currently the only NEO participating in the RSI Plan. The RSI plan was frozen and a nonqualified benefit plan was created to ensure employees who were in the RSI plan would receive the same level of benefits. The only difference in the new plan is that it requires a lump sum payment upon termination.

Assuming retirement at or after age 62, Mr. Molnar would receive an estimated monthly benefit of $4,454.

Perquisites and Other Benefits

During fiscal year 2015, we did not provide perquisites or personal benefits to executive officers, except those required under the separation agreement with Mr. Braun, other than leased automobiles, as disclosed in the Summary Compensation Table. As part of the separation agreement with Mr. Braun, the Company purchased Mr. Braun's former leased car and transferred ownership of that car to Mr. Braun. The value of the car has been disclosed in the Summary Compensation Table.

Employment Agreements with Named Executive Officers

Messrs. Merk and Hefter, and Ms. Mittelstaedt have employment agreements with us, under which they are entitled to specified base salaries, adjusted by the Compensation Committee, plus the opportunity to participate in the Cash Incentive Plan. Each employment agreement has an indefinite term, subject to termination by either the Company and RSL or the executive upon two years' prior written notice, in the case of Mr. Merk; upon two years' prior written notice to the end of the year, in the case of Mr. Hefter; and one year's written notice to the end of the fiscal year in the case of Ms. Mittelstaedt. In accordance with the employment agreements, each executive has agreed (i) not to disclose or exploit any of the Company's Confidential Information (as defined therein), and (ii) to assign to the Company all inventions or improvements made by the executive in the course of his or her employment with the Company, and not to compete with the Company for a six month period after the completion of his or her applicable term of employment. During the six month non-competition period, the executive is generally entitled under German law to receive half of his or her monthly salary. The employment agreements do not provide for severance. Mr. Molnar is subject to a written offer letter specifying his base salary plus the opportunity to participate in the Cash Incentive Plan. Mr. Seifert has an employment agreement with Nufern, a wholly-owned subsidiary of the Company, which provides for severance payments equal to one year’s salary in the event he is terminated without cause or resigns for good cause.

Change-In-Control Arrangements and Agreements

The Company does not have any change-in-control agreements or arrangements in place for any of its NEOs, other than the general change in control provision as described in our 2007 Incentive Stock Plan and our 2015 Incentive Plan as described later in this Annual Report.

Tax and Accounting Considerations

Tax Deductibility of Compensation Expense. Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code"), places a limit of $1,000,000 on the amount of compensation to certain officers that may be deducted by the Company as a business expense in any tax year unless, among other things, the compensation is performance-based and has been approved by the stockholders. To qualify as performance-based compensation, the amount of compensation must depend on the officer's performance against pre-determined performance goals established by a committee that consists solely of at least two "outside" directors who have never been employed by the Company or its subsidiaries. It is the policy of the Compensation Committee to periodically evaluate the qualification of compensation for exclusion from the $1 million deduction limit under Section 162(m) of the Internal Revenue Code while maintaining flexibility to take actions with respect to compensation that it deems to be in the interest of the Company and its stockholders which may not qualify for tax deductibility.

So that the Compensation Committee may retain maximum flexibility to structure performance targets based on corporate and individual metrics designed to achieve our various corporate goals, our Cash Incentive Plan does not conform to the requirements of Section 162(m). However, stock option awards granted to our executive officers have been structured so that the compensation realized when the stock options are exercised should be treated as performance-based compensation exempt from the deduction limitation of Section 162(m). The Compensation Committee does not believe that any loss of deductibility under Section 162(m) would have a material impact on the financial condition of the Company.

Tax Implications for Officers. Section 409A of the Internal Revenue Code imposes additional income taxes on executive officers for certain types of deferred compensation that do not comply with Section 409A. Because the Company does not provide deferred compensation to the NEOs, this limitation should not have an impact on the structure of the compensation program for the officers. Section 280G of the Internal Revenue Code imposes an excise tax on payments to executives of severance or change of control compensation that exceed the levels specified in Section 280G. The NEOs could receive the amounts as explained in the section entitled "Potential Payments Upon Termination or Change in Control" appearing later in this Annual Report as severance or change of control payments, but the Compensation Committee does not consider their potential impact in compensation program design.

Accounting Considerations. The Compensation Committee also considers the accounting and cash flow implications of various forms of executive compensation. In its financial statements, the Company records salaries and performance-based compensation incentives as expenses in the amount paid, or to be paid, to the NEOs. Accounting rules also require the Company to record an expense in its financial statements for equity awards, even though equity awards are not paid as cash to employees. The accounting expense of equity awards to employees is calculated in accordance with Financial Accounting Standards ("FASB") ASC Topic 718 (formerly known as SFAS 123(R)). The Compensation Committee believes, however, that the many advantages of equity compensation, as discussed above, more than compensate for the non-cash accounting expense associated with them.

Consideration of Compensation Programs and their Relationship to the Encouragement of Risk-Taking

The Compensation Committee has reviewed all of the plans described above, and does not believe that any of them encourage our NEOs to take unnecessary or excessive risks that threaten our value. The features of these plans do not make it likely that taking

- 15 -

unnecessary or excessive risks that threaten our value will provide greater compensation than actions that involve a prudent level of risk. The equity-based plans encourage our NEOs and other employees to focus on increasing shareholder value over a period of years. The pension plans provide helpful ways for our employees to save for retirement. The Compensation Committee believes that the plans described above do not pose any unnecessary risks, and do not encourage employees to manipulate reported earnings to enhance the compensation of any employee.

COMPENSATION COMMITTEE REPORT

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis included in this Annual Report on Form 10-K with management.

Based on such review and discussions, the Compensation Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this Annual Report on Form 10-K.

1. These columns consist of potential awards under our Cash Incentive Plan for fiscal year 2015. The Threshold column represents the minimum amount payable when threshold performance goals are met. The Target column represents the amount payable if specified performance targets are met. The Stretch column represents the amount payable if specified stretch performance goals are met. The Maximum column represents the maximum amount payable under the Plan for 2015 based on the highest target levels. Amounts are based on the executives' current salary as of the end of the Company's fiscal year. See the Summary Compensation Table for actual amounts earned under the Cash Incentive Plan in fiscal year 2015 and the information provided earlier under the Compensation Discussion and Analysis for a discussion of our Cash Incentive Plan. The Compensation Committee also included six-month performance goals, that if achieved, could add an additional 20% to the above targets.

2. Grant date coincides with the date the Compensation Committee approved the granting of shares. Additionally, the exercise price is equal to the closing market price for a share of our Common Stock on the date of grant.

3. The amounts listed reflect stock options granted under our 2007 Incentive Stock Plan and are described in the Outstanding Equity Awards at Fiscal Year End Table below.

4. The amount listed reflects a stock option granted under our 2015 Incentive Stock Plan and is described in the Outstanding Equity Awards at Fiscal Year End Table below.

5. The grant date fair value of the option awards has been computed in accordance with FASB ASC Topic 718 (formerly known as SFAS No. 123(R)), which requires that we recognize as compensation expense the value of all stock-based awards, including stock options, granted to employees in exchange for services over the requisite service period, which is typically the vesting period, but excluding forfeiture assumptions that are used in calculating equity award expense in the Company's financial statements. Refer to Note 19 to the Company's Consolidated Financial Statements on Form 10-K for the fiscal year ended September 30, 2015 for the relevant weighted-average assumptions underlying the valuation of the option awards.

OPTION EXERCISES

FISCAL YEAR ENDED SEPTEMBER 30, 2015

Potential Payments upon Termination or Change in Control

Effective March 12, 2015, our stockholders approved the Rofin-Sinar Technologies Inc. 2015 Incentive Stock Plan ("the 2015 Incentive Plan"). The 2015 Incentive Plan supersedes the Rofin-Technologies Inc. 1996 Non-Employee Directors' Stock Plan, the Rofin-Sinar Technologies Inc. 2002 Equity Incentive Plan and the Rofin-Sinar Technologies Inc. 2007 Equity Incentive Plan. Under the above stock option plans, unless the Compensation Committee determines otherwise in its sole discretion, if an employee's employment with the Company terminates by any reason other than death, disability, or retirement, an employee has up to sixty days from the date of such termination or until the expiration of the stated term of stock award, whichever period is shorter, to exercise any options that were exercisable on the date of such termination. If an employee's employment with the Company terminates by reason of death, disability, or retirement, an employee has up to one year from the date of such termination or, if earlier, until the expiration of the stated term of stock award, to exercise any options that were exercisable on the date of such termination.

Upon any Change in Control, the Board shall have the right to cancel all outstanding Options, Stock Appreciation Rights, Stock Grants and Stock Unit Grants after providing each Eligible Employee and Director a reasonable period to exercise his or her Options and Stock Appreciation Rights and to take such other action as necessary or appropriate to receive the stock subject to any stock grants or stock unit grants and the cash payable under any stock unit grants.

Except as otherwise provided in the applicable award agreement, and to the extent permitted under Section 409A of the Code, if an award granted under this Plan is assumed, continued, or replaced by the Company or successor after the Change in Control, and if the holder's service with the Company or its successor is terminated coincident with or within one year following the Change in Control either by the Company or its successor without Cause or by the holder for Good Reason (as such terms are defined in the plan), then all conditions to the exercise of such holder's outstanding Options and Stock Appreciation Rights on the date of termination and any and all outstanding issuance and forfeiture conditions on any Stock Grants and Stock Unit Grants held by the holder on such date automatically shall be deemed 100% satisfied as of the date of such termination of service.

The following constitute a change of control under the stock plans:

In addition, in accordance with German law and their employment agreements, each of Messrs. Merk and Hefter, and Ms. Mittelstaedt will, in the event they resign or are terminated by the Company, be entitled to receive one-half of his or her monthly salary if the Company determines to enforce their six month non-competition period. We would pay these amounts in equal monthly installments over six months.

The following table sets forth, for each of the following NEOs, the potential amount that such NEO would realize upon the exercise of vested options held by the NEO as of September 30, 2015, and the payments to which he or she would be entitled in connection with the non-compete clause in the relevant employment agreement, assuming a termination or change in control as of September 30, 2015. The amounts shown are based on the difference between the exercise price of the vested option and the closing price of the Common Stock on NASDAQ on September 30, 2015.

As noted above, effective July 1, 2015, Thomas Merk succeeded Günther Braun as President and Chief Executive Officer. In connection with the succession, on June 4, 2015, the Company and Mr. Braun entered into a Separation Agreement and General Release (the “U.S. Separation Agreement”) and ROFIN-SINAR Laser GmbH and CBL Verwaltungsgesellschaft mbH, two of the Company’s indirect wholly-owned German subsidiaries, and Mr. Braun entered into a Termination Agreement (the “German Termination Agreement”) in connection with Mr. Braun’s separation from the Company and its subsidiaries.

Pursuant to the U.S. Separation Agreement, Mr. Braun ceased to be an officer or director of the Company and its U.S. subsidiaries effective July 1, 2015, and he agreed to work with Mr. Merk to facilitate a smooth and orderly transition process through June 30, 2015. The German Termination Agreement terminated Mr. Braun’s existing employment agreement with his direct employer and provides that Mr. Braun will remain an employee and continue to receive his existing base salary through September 30, 2017 (the “Termination Date”), which period of continued employment and compensation is in accordance with the employment agreement that was terminated. The German Termination Agreement also provides that Mr. Braun will receive a bonus for each of 2015, 2016 and 2017 in the amount of 25% of the base salary. The U.S. Separation Agreement provides that Mr. Braun will remain eligible for continued vesting of previously awarded but unvested stock options in accordance with the applicable plan documents through the Termination Date, whereupon any remaining unvested stock options will become fully vested. Mr. Braun’s stock options will be exercisable through September 30, 2018. Both the U.S. Separation Agreement and the German Termination Agreement contain certain non-competition and non-solicitation restrictive covenants and releases of claims by Mr. Braun.

NON-EMPLOYEE DIRECTOR COMPENSATION

The Compensation program for non-employee directors is reviewed annually by our Compensation Committee to ensure the program remains competitive. As part of the Compensation Committee's review, the types and levels of compensation offered to our non-employee directors are compared with those provided by a select group of comparable companies. Additionally, in January 2012, the Company hired Radford, a third party compensation consulting firm, to assist with the analysis of the non-employee directors' compensation. The report has shown that the Company's average total non-employee director compensation approximates the market's 25th percentile. The Compensation Committee strives to set compensation levels that are competitive. The result of the report supports this goal.

Cash Compensation Paid to Board Members

Non-employee directors are entitled to receive an annual cash retainer in the amount of $35,000 for service on the Board and attendance fees of $2,000 for each Board meeting ($1,000 for telephonic meetings). Directors are also reimbursed for reasonable travel expenses incurred in connection with their duties as directors of the Company.

In addition to the annual retainer, each non-employee director who chairs the Audit, Compensation and Nominating Committees are entitled to an additional cash retainer in the amount of $10,000, $7,000 and $4,000, respectively, for such service. The Lead Independent Director is also entitled to an additional cash retainer in the amount of $12,000 for such service. Attendance fees are paid for Committee meetings as follows: $1,500 for each Audit Committee meeting ($750 for telephonic meetings), $1,000 for each Compensation and Nominating Committee meeting ($500 for telephonic meetings); and $1,500 for each other committee meeting ($750 for telephonic meetings), subject to review by the Board. Directors are also reimbursed for reasonable travel expenses incurred in connection with their duties as members of the Committees.

Non-cash Compensation

The Company has reserved an additional 1,800,000 shares of Common Stock under the 2015 Incentive Stock Plan approved at the Annual Meeting of Stockholders held on March 12, 2015, to provide for the grant of options to purchase Common Stock ("options"), grants of shares of Common Stock ("stock grants"), stock units, and stock appreciation rights ("SARs") to certain eligible employees and to non-employee directors. During fiscal year 2015, outside directors each received 3,000 shares of Common Stock that were fully vested upon grant.

The following table shows the compensation paid in fiscal year 2015 to our non-employee directors. Directors who are also officers do not receive separate directors' fees and have been omitted from this table if they appear in the Summary Compensation Table provided earlier in this Annual Report.

1.

Shares granted to non-employee directors vest immediately and therefore the fair value is equal to the closing market value on the date the shares were granted.

2. Mr. Baasel received $704,514 as rental payments for the building he owns in Starnberg, Germany (see note 14 of the Form 10-K Annual Report). Mr. Baasel also received $30,315 from the Company as management consulting fees.

3. Amounts paid in Euro have been converted into U.S. dollars at the weighted average exchange rate for the fiscal year: US$1.00: Euro 0.8710.4. In October 2009, Dr. Wirth retired as an executive of the Company. As Chairman of the Board, Dr. Wirth receives 40,000 Euros per year, payable

in four installments, one after each Board of Directors meeting.5. Dr. Wirth retired from the Company in October 2009; amount represents payments from the RSL Pension plan.
