Message from the President

President and CEO

Hitoshi Mizorogi

5DISCO CORPORATION

Since our establishment in 1937, DISCO Corporation has contributed to bringing

about a more prosperous, comfortable society by pioneering Kiru, Kezuru, Migaku

technologies for global industry. In 1995 we formulated the DISCO Vision, which

represents the desired future state of DISCO as a corporation, and is a milestone

we must achieve by 2010.

We have also formalized DISCO Values to clarify our values as a corporation.

These values cover everything, from the Company’s very reason for existence to

behavior guidelines for employees, and point to the mission we are called on to

pursue. We are striving for more than the mere pursuit of profit; our aim is to be a

corporation that is of value to all stakeholders, including shareholders, customers,

employees and local communities. To this end, it is important for us to work to

improve the corporate culture, to be recognized as a corporation of value and to

contribute to society. Sales, profit and financial performance overall are the

outcome of such pursuits.

The DISCO Group is primarily involved in the semiconductor industry, an extremely

challenging area of business. The pace of technological innovation is rapid and

market fluctuations are relentless. Nevertheless, with management guided by

DISCO Values, we intend to work to further increase our corporate value and

realize the DISCO Vision by carrying out business development oriented toward

our stakeholders.

Thank you for your continuing support.

Q

1

How do you read the recent changes in the operating environment?

NAND flash memory is one of the current drivers of the

semiconductor industry. Its compact size and large capacity have

led it to be used in cell phones, which are continually advancing in

terms of functionality, and a wide range of other applications,

including digital cameras and portable music players. System in

Package (SiP) technology is supporting the growth of NAND flash

memory.

Until recently the semiconductor industry had been focused on

System on a Chip (SoC) development. SoC involves placing

various functions on a single chip in order to miniaturize circuit

boards, but its development takes considerable time and costs are

high. In contrast, with SiP, multiple chips are sealed into a single

package, which enables high-function semiconductors to be

manufactured at relatively low cost. However, stacking multiple

chips requires making the wafers, the raw material for the chips,

exceedingly thin.

In response to this need for thin wafers, we provide solutions that

utilize proprietary thinning and stress relief technologies. There is

no doubt that our business opportunities will grow alongside

expansion of the market for SiP technology.

7DISCO CORPORATION


A

Q

2

What technologies is DISCO currently developing?

The DISCO Vision calls for establishing new pillars for our Kiru,

Kezuru and Migaku technologies alongside our existing abrasive

technology. Under this policy, along with making traditional abrasive

technology more advanced, we have made strides in developing

new technologies and applications using lasers, plasma, ultrasonic

waves and water jets.

Laser full-cut dicing is one result of these development efforts. It

involves laser irradiation of the top surface of thin wafers. As fragile

materials and wafers get thinner, dicing becomes more and more

difficult. Laser full-cut dicing serves to improve dicing speed and

throughput on thin wafers, such as those used in compound

semiconductors for high-frequency devices.

DISCO has also developed ultrasonic wave dicing as a new

application for electronic and optical components. This new

application of the technology facilitates the processing of materials

for which blade dicing proves difficult, such as glass, ceramics,

metals and resins.

Head Office/R&D CenterInvestment : ¥7.5 billion Completion: End of 2008 A

Q

3

What capital investments are you making in order to accommodate increasing demand?

DISCO’s target market, the semiconductor industry, is expected to

steadily expand. In fiscal 2006 we decided on three large capital

investment projects in anticipation of market growth:

1) expansion of our Head Office/R&D Center, 2) partial reconstruction

of the Kure Plant, and 3) partial reconstruction of the Kuwabata Plant.

1) We will add a new building in the grounds of our current Head

Office/R&D Center in order to further promote research and

development on laser saws, which are garnering attention as a new

processing method, and to accommodate equipment for larger-

diameter wafers. We will invest a total of ¥8 billion into the new

building, which will have a floor area of 26,400 m2. It is slated for

completion by the end of 2008.

2) At the Kure Plant, a new building is currently under construction

and should be finished by the end of 2007. It is being built in

anticipation of growth in demand for consumable blades and wheels.

A seismic isolation structure that minimizes potential earthquake

damage has been incorporated into the design in order to ensure

stable supply of our products to our global customers. Total

investment in the plant is ¥1.8 billion, and when complete, it will

increase our current production capacity by 50%.

3) At the Kuwabata Plant, also located in the city of Kure, we are

constructing a new building with a view to enhancing production

capacity and increasing production efficiency for precision processing

equipment and consumables. Total investment is ¥2.5 billion, and the

building is scheduled for completion by the end of 2007.

A

Q

4

What are your basic policies for investor relations and distribution of earnings to shareholders?

We recognize that building good relationships with shareholders and

investors is very important for our development as a corporation.

Based on this recognition, the entire group is working to improve

returns to our shareholders, and to increase corporate value.

On the matter of distributing earnings to shareholders, we revised

our dividend policy to link it to corporate performance beginning in

fiscal 2006 and changed our payout ratio to 20%. We also made

the decision to tack on one-third of the balance of excess cash to

the dividend when our current deposits exceed the amount

necessary for corporate operations. By striking a balance between

dividends and internal reserves, we will strive to realize sustained

growth and further increase corporate value.

To enable shareholders and investors to truly understand the

corporation, we are also devoting energy to investor relations

activities. We are working to build relationships of trust by promptly

and fairly disclosing information on important managerial issues

and data on financial performance, as well as by holding corporate

briefings as needed.

Moreover, to ensure that DISCO continues to merit the trust of

society, we are strengthening corporate governance, compliance

and CSR initiatives. I would like to express our gratitude to all our

shareholders for your robust, ongoing support.

Precision Processing Tooling Business: the Source of DISCO’s Strength

Strengthening the Precision Consumables Business to Flatten the Ups and Downs of the Silicon CycleThe semiconductor market swings wildly up and down with the

imbalances in supply and demand. This is known as the silicon

cycle. Our precision processing equipment is easily susceptible to

the impact of customer capital investment cycles, so sales figures

fluctuate considerably. Consumable items, such as precision

dicing blades and grinding wheels, on the other hand, are

indispensable to semiconductor production. Unlike precision

processing equipment, the sales volume of consumables

increases in direct proportion to the number of semiconductors

manufactured. Therefore, the influence of the silicon cycle is

smaller. Sales of consumables over the past 15 years have grown

at a rate of over 10% annually. DISCO’s consumables are the

product of our advanced proprietary technologies and are

extremely competitive in the market. The business constitutes a

stable source of revenue that underpins our financial performance.

Dicing Blade Grinding WheelGrinding Wheel

11DISCO CORPORATION

Consumables are used in DISCO dicers and grinders to provide quality and performance. They include Kiru products

like dicing blades for cutting wafers, Kezuru products like grinding wheels, and Migaku products like dry polishing

wheels. We fully leverage the expertise we have accumulated since our founding to develop and manufacture these

products to meet the needs of our customers.

Capacity ExpansionThe consumables business is expected to see steady growth

driven by the expansion in semiconductor applications. There

is currently a mounting need for new consumables owing to

the development of new semiconductor materials and the

increasing complexity of processing technologies.

To accommodate this growth in demand, DISCO is

constructing a new facility at our plant for consumables in

Kure, Hiroshima prefecture.

The new building will adopt a seismic isolation structure to

mitigate earthquake risk and ensure stable product supplies

to our global customers. Production capacity is scheduled to

increase by about 50% when the building is completed in

2007.

Blade CharacteristicsDISCO precision dicing blades are primarily made of abrasivesand bond. Abrasives serve as the cutting material for processing,while the bond holds the abrasives in place.

��

��

��

��

Blade MechanismPrecision dicing blades differ from normal cutting tools in that theyenable a special kind of processing function known as self-sharpening. During processing, new abrasives emerge so that theblade is constantly maintained in good condition.

��

��

��

The bond that holds the abrasives in place is graduallyworn away by the stress of processing and grainsgiven off by the cutting work (the blade wears in aninward direction).

The abrasives that do the cutting are therefore strippedaway and new abrasives emerge on the surface toserve as the new cutting blade for processing.

DFL7160 Advancing Kiru Technology

DFL7160

In order to accommodate increasingly sophisticated

semiconductor manufacturing processes, DISCO

offers not only conventional blade dicing but also a

lineup of precision cutting technologies that use

lasers.

The DFL7160 provides high speed, high quality

processing using lasers for full cutting and grooving,

and can be used to process materials and devices

that are difficult to process with conventional blade

dicing. The DFL7160 is a fully automatic laser saw

compatible with 300 mm wafers that is capable of

integrated processes from washing to drying.

13DISCO CORPORATION

Grooving of materialsfor high-performancedevicesThe system can cut metalization, test targets and low-k

film, which is widely used with high-performance

devices, without causing thermal warping or cracking.

It is normally quite difficult to obtain high levels of

productivity using conventional diamond blade dicing

on compound materials such as Gallium Arsenide

(GaAs), which is used in high-frequency devices.

Manufacturing technologies for thin, strong die is

required by System in Package (SiP) technology, which

is used to produce thinner, highly functional mobile

phones and memory cards. However, the thinner the

wafer, the more difficult blade dicing becomes. DISCO

has worked to solve this problem by optimizing the

laser head and optical system of the DFL7160, and has

succeeded in establishing a laser full-cut application.

Full Cut Dicing of Thin Silicon WafersAs wafers have become thinner, chipping or cracking

during dicing has a major impact on die strength. For

this reason, there is demand for a form of processing

that reduces chipping. In addition, an increasing

number of devices use Die Attach Film (DAF) as the

adhesive material for stacking thin die, so burr

reduction and dicing quality have also become issues.

In response, DISCO has developed an application that

performs laser full-cut dicing as one of the thin wafer

solutions for silicon. Throughput improvement can be

expected thanks to high-speed laser processing. For

wafers with DAF attached, laser dicing can be

performed on the silicon and DAF together or

separately.

Expanded use of the laser process

Laser process enables DISCO to cut material that was difficult with conventional blades.

DISCO Values

DISCO formalized DISCO Values as a management nucleus and a system of corporate philosophies to be relied on

for all business activities. DISCO will increase its exchange of value with its stakeholders for future corporate growth.

Structure of DISCO ValuesDISCO Values were formalized in 1997 as a result

of a project that was initiated in December 1995 by

the top management with the intent of creating a

more dynamic corporate culture. DISCO Values

respond to the question “Why does DISCO exist?”

and systematically summarize the Company’s

original values. At the same time, they provide for

future perspectives on how DISCO should be and

what DISCO should do to promote future

development while respecting its accumulated

traditions.

DISCO annually verifies DISCO Values and

modifies them as required to keep the content

optimally relevant.

Corporate Growth at DISCODISCO embodies basic ideas for its future-oriented

business activities in the form of a Management

Model. In this model, DISCO’s growth is fulfilled not

by quantitative scale expansion, such as a rise in

net sales or an increase in the number of offices and

employees, but rather by the achievement of the

Mission, which increases the exchange of value with

our stakeholders.

Based on the idea of exchange of value, whereby

corporations are a social system for value exchange

among a variety of people, DISCO views its

corporate growth in terms of increasing this

exchange of value with our stakeholders and

accordingly promotes stakeholder-oriented

management.

Management’s Discussion and Analysis


Business Overview andResults of OperationsSummary of Results of OperationsFor the consolidated fiscal year under review, strong capitalinvestment by semiconductor manufacturers havecontinued, supported by demand for end-user application ofdigital products worldwide. Although the industry hasentered in the adjustment period in 2007, orders forsemiconductor equipment remained in a steady growth.

Regarding the Group's business operations, due to strongdemand from both home and abroad, sales and orderscontinually increased, generating record-high Q4 sales onquarterly basis. Especially sales of precision processingequipment for memory device and of grinding equipment formaterial wafers saw a considerable increase. Further, salesof precision processing tooling (consumables) grew,reflecting increase in number of semiconductor productionunits. The Group focused on improving customer’s valuewhile implementing aggressive sales activities. As a result,consolidated net sales for the fiscal year under review rose25.1% to ¥86,161 million, achieved the highestperformance in the past. Operating income climbed to40.0% to 19,524 million and consolidated net incomeincreased 32.9% to ¥10,936 million. In addition, share ofconsolidated net sales attributed to those overseas rose to66.0%, from 64.7% for the previous year, a gain of 1.3points.

Net SalesConsolidated net sales hit a record ¥86,161 million or up25.1% from the previous year. The strong results wereattributable to a sharp increase in sales of grinders formemory device and material wafer processing, reflectingsemiconductor manufacturers’ strong capital expenditures,and robust sales of consumables amid rising production ofsemiconductors.

Cost of salesReflecting higher net sales, the cost of sales increased¥9,373 million from the previous period to ¥42,107 million.Despite an increase in sales of high-margin consumables,overall profit margin remained flat because model changesof precision processing equipment almost finished and

higher sales were seen in the Asian region, where pricecompetition was fierce. Cost of sales ratio climbed 1.4percentage points to 48.9%.

Selling, General and Administrative ExpensesSelling, general and administrative (SG&A) expenses grew¥2,328 million to ¥24,530 million from ¥22,202 million overthe previous year, mainly because of the following factors:R&D expenses rose ¥47 million to ¥6,389 million, from¥6,342 million over the previous year. The majority of R&Dexpenses were used for the Electronics Industry-RelatedProducts division and we expect this strategic expense willtranslate into increased future earnings. Salaries, bonusesand provision for staff bonus reserve rose ¥950 millioncompared with the previous period, reflecting a largerworkforce, higher bonuses due to improved earnings, andincreased overtime work resulting from activities forreceiving orders. Sales commissions, packing and freightexpenses, and warranty cost, which vary proportionatelywith sales, increased by a combined ¥813 million over theprevious year, owing to a rise in sales.

As a result, SG&A expenses rose from the previous year,but this rise was offset by an increase in net sales. Hence,the ratio of SG&A expenses to net sales declined 3.9percentage points, compared with the previous year to28.4%.

Operating IncomeOperating income rose ¥5,575 million to ¥19,524 million,from ¥13,949 million for the previous year. This rise wasmainly attributable to a substantial increase in operatingincome in the Electronics Industry-Related Productsdivision, although such income dropped in the IndustrialProducts division.

Other Income (Expenses) Other income (expenses) increased ¥1,245 million to¥1,808 million (net), compared with an income of ¥564million (net) for the previous year. The increase was mainlydue to a valuation of inventories of ¥402 million and adisposal of inventories of ¥370 million. With regard toS.E.A. Utensili Diamantati S.p.A., an equity-method affiliate,the Group booked ¥157 million in losses on valuation ofinvestment securities and ¥204 million in provision ofallowance for doubtful accounts, as the Group’s IndustrialProducts division withdrew from products for stonematerials.

Income Before Income Taxes and Minority InterestsFor the above reasons, income before income taxes andminority interests increased ¥4,331 million from, ¥13,385

Minority Interests Minority interests earned ¥50 million attributable toconsolidated subsidiaries, such as DISCO TECHNOLOGY(SHANGHAI) CO., LTD. and DSD, Ltd.

Net Income Net income rose ¥2,706 million, to ¥10,936 million,compared with ¥8,230 million for the previous period.

Basic net income per share posted ¥322.32, comparedwith ¥252.82 in the previous year. Diluted net income pershare rose to ¥321.22, from ¥251.85 in the previous year.

Business Performance by SegmentElectronics Industry-Related Products DivisionThe Electronics Industry-Related Products division, ourcore business segment, manufacturers and marketsprecision processing equipment, such as dicing saws andgrinders; precision processing tooling (consumables suchas blades and wheels); and precision electroniccomponents. The division also provides full after-salesservice. In the consolidated fiscal year under review, theequipment and tooling for precision processing enjoyedlarge sales due to semiconductor manufacturers’ highutilization of capacity. By product, sales of cuttingequipment for electronic components and opticalsemiconductors were high. Also, sales of grindingequipment increased sharply, driven by our strategicproduct, thinning and stress-relief equipment, and surfacegrinding equipment for material wafers.

As a result, sales for the consolidated fiscal year underreview grew 26.3% over the previous period to reach¥83,429 million. Also operating income rose 33.4% over theprevious period, to reach ¥22,431 million.

Industrial Products Division and Other ProductsDivisionThe Industrial Products division manufactures and marketsindustrial diamond tools and general cutting and grindingtools, mainly for the civil engineering sector.

Despite aggressive marketing activities during the yearended March 31, 2007, sales by the division, on aconsolidated basis, declined 2.7%, to ¥2,468 million, owing

to national and local government policies, that haveconstrained public works expenditures. Operating incomealso fell 32.0% from that of the previous period, amountingto ¥145 million.

Regarding to S.E.A. Utensili Diamantati S.p.A., an equity-method affiliate, the Group posted ¥157 million fordevaluation loss on investment securities, and ¥204 millionfor provisions for bad debt, owning withdrawal from themarket of industrial grinding products business for stonematerial products.

The Other Products division focuses on the developmentand marketing of computer software, mainly targeted atsemiconductor equipment and device manufacturers. On aconsolidated basis, sales by the division decreased 12.0%from the previous period, to ¥264 million, while netoperating income increased 317.1% over the previousperiod, amounting to a gain of ¥45 million.

Geographic Segment InformationDomestic SegmentThis segment includes not only sales in Japan, but alsosales in Korea and Taiwan, etc. where the Group directlyexports without involving the Group’s overseas subsidiariesand markets through local distributors. Especially in Asia,for the consolidated fiscal year under review, net sales were¥53,585 million, up 29.9% over the previous year andoperating income also rose to ¥20,193 million, an increaseof 40.0% from the previous period. This is due to sharpincrease in orders for industrial grinding equipment forelectronics components in Japan as well as in Asia, whichwas driven specially by strong capital investment frommemory manufacturers in Korea, including subcontractors.

Overseas Segment The Group experienced remarkable sales growth in mostoverseas markets. Notably, sales of memory-relateddevices were favorable in Asian region. Net sales in NorthAmerica were ¥6,517 million, up 14.6% from the previousyear and net operating income rose to ¥248 million, up40.7% from the previous year. Sales in Asia were ¥16,410million, up 7.7% over the previous period, while netoperating income was ¥903 million, a decrease 55.0%compared with the previous period. Net sales in Europewere ¥9,649, an increase of 43.9% from the previous fiscalyear, and net operating income was ¥1,715 million, a rise of67.4% comparing with the previous period.

As a result, net sales in North America increased 10.8%


from the previous period, to ¥5,919 million, in Asia was¥41,107 million, an increase of 25.3% from the previousperiod and in Europe was ¥9,798, an increase of 52.7%over the previous period to ¥9,797 million. Hence, total netsales in overseas segment to the consolidated net sales forfiscal year under review rose 1.3 points compared with theprevious year to 66.0% (64.7% for the previous year).

Liquidity and Capital Resources Assets, Liabilities and Shareholders’ EquityIn the fiscal year under review, total assets for theconsolidated fiscal year under review increased ¥14,472million over the previous year to ¥113,791 million. The mostsignificant factors contributing to this growth were increasesin notes and accounts receivable-trade, and cash and cashequivalents.

As for current assets, total current assets rose to ¥75,799million, up ¥11,520 million, owing to increase in notes andaccounts receivable-trade and inventories amid robustsales. Quick assets, the sum of cash and cash equivalents,and notes and accounts receivable-trade, totaled ¥51,842million, leaving the Company in a sound position to covercurrent liabilities which stood at ¥28,819 million at the endof the period.

Fixed assets for the consolidated fiscal year under reviewrose ¥2,952 million to ¥37,992 million, due primarily toconstruction of new building in the premise of HeadOffice/R&D Center, and Kure and Kuwabata plants.

Current liabilities decreased ¥1,985 million becausebonds with share warrants to be redeemed within one yearwere all redeemed. Meanwhile, the sum of notes payable-trade, accounts payable-trade, accrued expenses, incometax payable, etc. rose ¥2,758 million reflecting strong sales.As a result, current liabilities increased rose to ¥28,819million, up ¥3,325 million from the previous term.

Long-term liabilities rose ¥25 million to ¥3,148 millionfrom the previous year.

Minority interests for the consolidated fiscal year underreview rose ¥26 million to ¥451 million, compared with theprevious period.

Total shareholders’ equity grew ¥10,785 million to¥80,552 million. This was primarily due to increases incommon stock and additional paid-in capital totaling ¥2,146million, following the exercise of new share warrants of thenotes with stock acquisition rights and stock options, and arise in retained earnings of ¥8,653 million. Beginning in theconsolidated fiscal year under review, the Companyadopted “Accounting Standards for Share-Based

Compensation.” (Statement No. 8 issued by the AccountingStandards Board of Japan on December 27, 2005). Withthis adoption, we booked share subscription rights of ¥66million.

Cash FlowsWhile income before income tax increased 32.4%compared with the previous year to ¥17,716 million, cashand cash equivalents at the end of the consolidated fiscalperiod (hereinafter “Cash”) increased by ¥2,041 million asresult of payment of corporate tax payment and payment foracquisition of tangible fixed assets of ¥6,498 million and¥4,899 million, respective by, reflecting strong salesactivities.

Major factors for the above for the consolidated fiscalyear under review were as follows.

Cash flow provided by operating activitiesNet cash provided by operating activities at the end of theconsolidated fiscal period under review were ¥13,194million. This was mainly attributable to decrease in Cash bypayment of corporate taxes in the amount of ¥6,498 million,while there was an increase in income before income taxesand depreciation and amortization of each ¥17,716 millionand ¥2,964 million.

Cash flow used in investing activitiesNet cash used in investing activities at the end of theconsolidated fiscal period under review was ¥8,952 million,chiefly because of the following factors: investment inproperty, plant and equipment of ¥4,899 million forconstructing new building of the Head Office/R&D Center,Kure and Kuwabata plants, and disbursement for timedeposits of ¥3,000 million.

Hence, free cash flow adding up net cash flows fromoperating activities and investing activities at the end of theconsolidated fiscal period under review was ¥4,242 million(¥7,914 million for the previous year).

Cash flows used in financing activitiesNet cash used in financing activities at the end of theconsolidated fiscal year under review was ¥2,429 million.This was mainly due to the payment of dividends of ¥2,191million and repayment for short-term borrowings of ¥306million.

Financial PoliciesAs a general principle, the DISCO Group satisfies most ofits working capital and property, plant and equipmentfunding requirements through the use of its internal free

cash flows. Fluctuations in the Group’s operatingperformance may be significant, mainly owing to stronglinkage with the silicon cycle. Additionally, the developmentof the Group’s business requires us to actively take onbusiness risks, and, to balance this, we believe it isimportant for us to minimize the Group’s exposure tofinancial risk and build a high level of risk tolerance into ourfinancial structure. This has led us to develop a policy of notincreasing the Group’s interest-bearing debt, and, inparticular, bank borrowings.

When the need for large, one-off funding does arise, it isour policy to utilize direct financing sources in the financialmarkets, such as through secondary public stock offerings,which serves to keep financial risk at a minimum. Atpresent, we believe the Group has achieved a high degreeof financial stability primarily due to its low level of interest-bearing debt—mainly in the form of long-term borrowings—relative to its asset base.

To satisfy working capital requirements, each companywithin the Group arranges its own short-term borrowings(up to 12 months). In some cases, however, where fundingcost differentials are significant, the Group parent companymay raise funds and provide loans to consolidatedsubsidiaries as necessary.

As of the end of the consolidated fiscal year underreview, short-term loans stood at ¥300 million, all frombanks. In addition, property, plant and equipment fundingrequirements are satisfied through long-term loans, and asof the end of the consolidated fiscal year under review,long-term loans stood at ¥828 million, again all from banks.

We believe the Group remains in a strong position tomeet its ongoing working capital and capital expenditurerequirements and to facilitate its future growth. This positionis underpinned by the Group’s sound financial base and itsability to generate sufficient operating cash flows.

Risk FactorsBusiness and other risks which may materially affect to theGroup’s business, financial positions and the decisions ofour investors are as follows:

Cyclical Nature of the Semiconductor Market The Group manufactures precision equipment along withprecision processing tooling used in this equipment, andsells these products to semiconductor manufacturersworldwide. The semiconductor market is characterized byextreme volatility and large fluctuations in the balancebetween supply and demand. Consequently, the businessperformance of semiconductor manufacturers is strongly

affected by this, the so-called “silicon cycle.” Besides globalmacroeconomics trends, this cycle is influenced by suchfactors as; (1) supply and demand conditions andtechnology trends in consumer and industrial electronicsmarkets; and (2) the number of semiconductors used ineach end-user product and the processing capacity of thosesemiconductors. As a result, it is very difficult to producereliable forecasts concerning the semiconductor market.

The Group has made considerable efforts to structure itsbusiness in such a way that it remains profitable evenduring the downward phase of the cycle. Nonetheless, thebusiness performance of the Group may be unavoidablyaffected by cyclical fluctuations in the semiconductormarket that lead to slumps in the plant and equipmentinvestment trends of semiconductor manufacturers.

International Division of Labor in the SemiconductorManufacturing Industry In recent years, semiconductor manufacturers haveincreasingly shifted away from the traditional system ofcarrying out the entire production process in-house towardan outsourcing-based model. Under this new system,certain parts of the production process are outsourced tosilicon foundries and assembly subcontractors—mainly inAsia—leading to progressively greater horizontal division oflabor across countries and regions. Reflecting this change,the proportion of the Group’s sales generated in the Asiaregion has risen substantially over recent years. To acertain extent, by shifting to such a production system,semiconductor manufacturers are passing on some of thecyclical business risk associated with market fluctuations tothe foundries and subcontractors, which, in turn, tend toadopt a plant and equipment investment stance that is moresensitive to fluctuations in the semiconductor market thantraditional semiconductor manufacturers.

Consequently, the market-driven plant and equipmentinvestment conditions at foundries and subcontractors mayaffect the Group’s business performance.

Concentration of Business among Certain CustomersThe Group maintains business relationships with all of theworld’s major semiconductor manufacturers. Within thesemiconductor sector, there is a continuing trend towardmergers and acquisitions aimed at securing competitiveadvantage, as well as toward a very select group of leadingfirms becoming ever more dominant in terms of marketshare. These types of trends may be a factor in limiting thepool of potential customers for the Group’s products.

The Group’s business performance may also be affectedby the concentration of its business, at certain times,among a limited number of specific customers, who may


use this situation as leverage during price negotiations. Thiscould lead to volatility in the prices and profitability of theGroup’s products.

Emergence of New Technologies The Group’s main products at present are precisionequipment and precision processing tools, for theprocessing of semiconductor silicon wafers. The currentmethod of cutting wafers using diamond blades becameestablished in the past as the optimal method for this taskas a result of semiconductor and electronic componentmanufacturers conducting extensive technical evaluationsof various possible methods. However, in the future,substitute technology may emerge, which may have anegative impact on the Group’s business performance.

In recent years, laser cutting technology has receivedmuch attention. The Group developed and sells laser sawsfor cutting materials that are difficult to cut efficiently usingprecision dicing blades.

Product Development Capabilities In fields where the pace of technical innovation isparticularly rapid, such as that of semiconductors andelectronic components, maintaining a competitiveadvantage in technology requires ongoing investment inresearch and development regardless of short-term marketfluctuations. To precisely meet the needs of its customers,which are becoming more diverse and sophisticated eachday, the Group allocates the maximum level of resourcespossible to R&D activities as one of management’s highestpriority tasks. However, by its very nature, productdevelopment is very complex and involves an extremelyhigh level of uncertainty. If the Group were not able toadequately predict changes in the industry and market, and,therefore, were not able to introduce attractive products tothe market in a timely manner, the Group’s businessperformance may be negatively affected.

Acquiring and Cultivating Key Human Resources As the Group’s future growth is greatly dependent onhaving talented engineers and other key human resources,the task of acquiring and cultivating these human resourcesis an extremely important issue for management. If theCompany cannot acquire or cultivate key human resources,this may negatively affect the Group’s future growth andbusiness performance.

Exchange Rate FluctuationsThe Group conducts its business not only with customers inJapan but also with semiconductor and electroniccomponent manufacturers in the United States, Europe and

Asia. For this reason, to enable the Group to rapidly andeffectively sell its products and provide after-sales serviceto semiconductor and electronic component manufacturers,it has established a network of sales and servicesubsidiaries in the United States, Europe and Asia. Whenthe Group exports products from Japan, depending on theregion or customer in question, currencies other than theJapanese yen, including the U.S. dollar, the euro and theSingapore dollar, may be used for the settlement oftransactions. As the Group’s products are, for the most part,manufactured in Japan, manufacturing costs are incurred inJapanese yen.

Consequently, as a general rule, a rise in the value of theyen has a negative effect on the Group’s businessperformance and a fall in the value of the yen has a positiveeffect. In this way, fluctuations in exchange rates may affectthe Group’s operating results.

Earthquake DisastersMany of the Group’s production facilities are located inHiroshima City and its corporate headquarters is located inTokyo, Japan, where a severe earthquake could strikeanywhere at any time. If a severe earthquake were to hitthe Group’s production facilities, it would cause a halt inproduction, and in the case of the Group’s headquarters,this would adversely affect the Group’s management.Further, depending on conditions, it would also adverselyaffect the Group’s business performance.

Other FactorsIn the conduct of its business, in addition to theaforementioned risk factors, the Group’s businessperformance may also be affected by economic crises,natural disasters, war and terrorist actions, epidemics,financial and capital markets, laws and governmentregulations, product defects, supply systems, intellectualproperty rights, and other factors, both global and regional.

(4) New dicing blade VT07 seriesDISCO has developed a new dicing blade series using theoutstanding grinding ability of vitrified bond. Vitrified bond,with a proven track record grinding wheels, is now usedcommercially as a thin dicing blades, which have beendifficult to manufacture until now. The VT07 can achieveexcellent results with high-load processing, such as deepcutting of very hard materials like silicon nitride, by takingadvantage of the high rigidity and high-grinding ability ofvitrified bond.

(5) New wheel BR385A BR385 bond wheel, suitable for grinding glass, has beenadded to the lineup of the GF01-series grinding wheel.Application of the newly developed resin bond to both roughand finish grinding processes has now made it possible tocarry out high-grade grinding of fine surfaces. Given itssuperior grinding ability, the BR385 also makes it possible toachieve continuous grinding of glass in a stable mannerwithout intermediate dressing.

(6) Precision-processing components andsemiconductor-related components DISCO has invested actively in the development of precision-processing components, such as for MEMS sensor devices,RF powers, digital devices, glass wafer processingtechnology for combined biological/medical-use, andmicrofabrication technique for water-cooled heatsinks forcooling of next-generation high-power laser diodes.

DISCO has also advanced investments in the developmentof a microfabrication technology aimed at application of high-performing materials to support the heatsink market whereincreasingly high functionality is demanded.

R&D expenses in this division totaled ¥6,317 million.

Industrial Products Division(1) DISCO advanced initiatives to stabilize the performingquality of ultra-thin cutting wheels and CBN electrocoatwheels to meet the needs of the auto-related industry.

(2) DISCO has developed and launched new thin-bladed wetsegment saws, housed in lightweight aluminum shells withsilent cup wheels, as general-purpose ceramic tile cutters tomeet the needs of the construction processing market.

R&D expenses in this division totaled ¥97 million.

Electronics Industry-Related ProductsDivision(1) Edge profiling grinding technologyNext generation ultra-compact memory cards, developed tosupport the miniaturization and high-functionality of mobilephones and digital cameras, are becoming smaller andthinner based on die thinning and unified molding of the dieand package. Currently, a processing method, based oneither laser or water jet, is being used for curvilinearprocessing to trim the shape of the package edges afterunified molding. As a new processing method for thiscurvilinear process, DISCO has developed the edge profilegrinding technology that uses a purpose-built blade to attainbetter quality and lower-cost processing, based on DISCO’sabundant development experience in diamond wheels anddicing saws.

(2) R07 series BB100 bond blade for processing glass,quartz, etc.DISCO has developed a resin R07 series BB100 bond bladefor high-grade processing of hard and brittle materials suchas glass, quartz and ceramics. BB100’s characteristicfeatures lie in its higher thermal conductivity and strongerabrasive coating retention compared with conventional resinblades, which makes it possible to reduce instances ofchipping (or cracks occurring on the deburred planes due togrinding load) and improving both processing quality andprocessing speed.

(3) Cutting blade ZP07 for glass and silicon bondedwafersDISCO has developed a new electroformed blade ZP07series to enhance the processing performance of difficult-to-cut materials. The ZP07 combines high cutting ability, whichis specific to electroformed bonded blades, and appropriateself-sharpening ability, by forming pores in the electroformedbond to make a porus structure. It enables simultaneouscutting of glass and silicon wafers in a single pass, yieldingfavorable processing results on the surface of both glass and

Notes to ConsolidatedFinancial Statements

1. BASIS OF PRESENTING CONSOLIDATED FINANCIAL STATEMENTSThe accompanying consolidated financial statements of DISCO CORPORATION (“the Company”) and its consolidated subsidiaries havebeen prepared in accordance with the provisions set forth in the Japanese Securities and Exchange Law and its related accountingregulations, and in conformity with accounting principles generally accepted in Japan (“Japanese GAAP”), which are different in certainrespects as to application and disclosure requirements of International Financial Reporting Standards.

The accounts of Company’s overseas subsidiaries are based on their accounting records maintained in conformity with generallyaccepted accounting principles prevailing in the respective countries of domicile. The accompanying consolidated financial statementshave been restructured and translated into English (with certain expanded disclosure and the inclusion of the consolidated statements ofchanges in net assets for 2006) from the consolidated financial statements of the Company prepared in accordance with Japanese GAAPand filed with the appropriate Local Finance Bureau of the Ministry of Finance as required by the Securities and Exchange Law. Certainsupplementary information included in the statutory Japanese language consolidated financial statements, but not required for fairpresentation, is not presented in the accompanying consolidated financial statements.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIESa. Principles of Consolidation – The accompanying consolidated financial statements include the accounts of the Company and itssignificant subsidiaries (collectively, “the Companies”). Consolidation of the remaining subsidiaries would not have a material effect onthe accompanying consolidated financial statements. The Company has immaterial investments (of three and three subsidiaries) thatshould be consolidated in the accompanying financial statements (as of March 31, 2007 and 2006, respectively).

All significant intercompany accounts and transactions have been eliminated on consolidation. All material unrealized profits includedin assets resulting from transactions within the Companies have been eliminated.

Investments in significant associated companies are stated at their underlying equity value, and the companies’ share of the income orloss of such companies is included in consolidated income. In addition, the Company accounts for its unconsolidated subsidiaries andassociated companies under the cost method (of six and six entities at March 31, 2007 and 2006, respectively). The effect on theconsolidated financial statements of not applying the equity method was immaterial.

Two subsidiaries which had December 31 year ends closed their accounts tentatively at March 31. Two subsidiaries with a December 31year ends accounted for any major transaction that took place between December 31 and March 31 for these subsidiaries in theaccompanying consolidated financial statements.

Prior to April 1, 2006, goodwill is principally amortized over the expected periods to be benefited. Effective form year ended March 31,2007, negative goodwill is amortized over 5 years by the straight-line method.

b. Cash and Cash Equivalents – For purposes of the consolidated statements of cash flows, the Company considers all highly liquidinvestments, including time deposits with a maturity of three months or less when purchased, to be cash equivalents.

c. Inventories – Inventories of the Company and its domestic subsidiaries are stated at cost. The cost of finished goods and work inprocess is determined principally by the job-identification-cost method or average cost method. The cost of merchandise and rawmaterials of the Company and its domestic subsidiaries are determined principally by the average cost method.

Merchandise and finished goods of foreign subsidiaries are stated at the lower of cost (determined by the average cost method) ormarket value.

d. Marketable and Investment Securities – The Companies classify their debt and equity securities into one of the following threecategories: trading, held-to-maturity, or other securities. All securities of the Companies are classified as other securities. The Companieshave no trading and held-to-maturity securities.

Other securities with fair market value are principally carried at the fair market value. The difference between the acquisition cost andthe carrying value of other securities, net of related tax effect, is recognized in “Other securities valuation difference” as a separatecomponent of net assets until realized. Other securities without fair market value are stated at cost. The cost of other securities sold isprincipally computed based on the moving average method.

e. Derivatives – Derivative financial instruments are stated at fair value and changes in the fair value are recognized in the consolidatedstatements of income unless the derivative financial instruments are used for hedging purposes.

f. Property, Plant and Equipment – Property, plant and equipment are stated at cost. Depreciation is computed principally by thedeclining-balance method at rates based on the estimated useful lives of the assets. The straight-line method has been applied to newlyacquired buildings since April 1, 1998. The range of useful lives is principally from 3 to 38 years for buildings and structures, from 3 to 10years for machinery and equipment, and from 2 to 20 years for tools, furniture and fixtures.

g. Retirement Benefits – Employees of the Company and consolidated domestic subsidiaries are covered by an unfunded, non-contributory, defined benefit retirement plan. In addition, the Company and two of the domestic subsidiaries have funded,noncontributory, defined benefit pension plans, the funds of which are placed in trust with a private life insurance company and a trustbank. Certain consolidated overseas subsidiaries have defined contribution retirement plans.

Provisions for unfunded retirement benefits to directors and corporate auditors of two of the domestic consolidated subsidiaries werecalculated to accrue the amount required to be paid if all directors and statutory auditors retired at the balance sheet date.

h. Research and Development Expenses – Research and development expenses are charged to income when incurred.

i. Income Taxes – The Companies recognize deferred taxes for the estimated tax effects of temporary differences between the financialreporting and the tax basis of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates applicable to


the periods in which the temporary differences are expected to be recovered or settled.

j. Per Share Information – The computation of net income per share is based on the weighted average number of shares of commonstock outstanding during each year. The average number of shares of common stock used in the computation was 33,929,583 sharesand 32,198,116 shares in 2007 and 2006, respectively.

Cash dividends per share are based on cash dividends declared with respect to income for the year.

k. Foreign Currency Translation – In accordance with the accounting standards for foreign currency translation issued by The BusinessAccounting Deliberation Council, foreign currency transactions are translated into Japanese yen at the rates in effect at the transactiondate.

At the year-end, receivables and payables denominated in foreign currencies are translated into Japanese yen at exchange rates ineffect at the balance sheet date. Resulting translation effects, including gains and losses on settlement, are credited or charged tocurrent income.

Investment securities and investments in unconsolidated subsidiaries and associated companies denominated in foreign currencies aretranslated into yen at the historical rates prevailing at the date of transaction.

Foreign exchange contracts are marked to market and included in other assets or other liabilities, with offsetting gain or loss included inother income or expense (the fair value method).

For consolidation purposes the financial statements of overseas subsidiaries are translated into Japanese yen, the reporting currency,as follows: all assets and liabilities are translated at the year-end exchange rates; shareholders’ equity accounts are translated athistorical rates; and revenue and expense items are translated at average rates. Translation adjustments are included in the net assetssection of the consolidated financial statements.

l. Leases – Leases are accounted for principally as operating leases. Under Japanese accounting standards for leases, finance leasesthat do not transfer ownership of the leased property to the lessee are permitted to be accounted for as rental transactions if certain “as ifcapitalized” information is disclosed in the notes to the lessee’s consolidated financial statements.

m. Use of Estimates – The preparation of the consolidated financial statements requires management of the Companies to make anumber of estimates and assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent liabilities atthe date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. Significantitems subject to such estimates and assumptions include the valuation of receivables, inventories and deferred income tax assets andassets and obligations related to employee benefits. Actual results could differ from those estimates.

n. Reclassification – Certain prior year amounts have been reclassified to conform to the current year presentation. These changes hadno impact on previously reported results of operations or retained earnings.

o. Net income per share – The basis of net income per share of common stock for each year is computed based upon the weightedaverage number of common shares outstanding during the year. The diluted net income per share assumes full exercise of potentiallydilutive securities outstanding at the end of the year.

p. Accounting Standard for Presentation of Net Assets in the Balance Sheet – Effective from the year ended March 31, 2007, theCompany and its consolidated subsidiaries adopted the new accounting standard, “Accounting Standard for Presentation of Net Assetsin the Balance Sheet” (Statement No.5 issued by the Accounting Standards Board of Japan on December 9, 2005), and theimplementation guidance for the accounting standard for presentation of net assets in the balance sheet (the Financial AccountingStandard Implementation Guidance No. 8 issued by the Accounting Standards Board of Japan on December 9, 2005), (collectively, the“New Accounting Standards”).

Under the New Accounting Standards, the balance sheet comprises three sections, which are the assets, liabilities and net assets sections.Previously, the balance sheet comprised the assets, liabilities, minority interests, as applicable, and the shareholders’ equity sections.

Under the New Accounting Standards, the following items are presented differently compared to the previous presentation. Sharesubscription rights and minority interests are required to be included in the net assets section under the New Accounting Standards.Under the previous presentation rules, companies were required to present share subscription rights and minority interests in the currentliabilities section and between the non-current liabilities and shareholders’ equity sections, respectively.

The consolidated balance sheet as of March 31, 2006 has been restated to conform to the 2007 presentation. There were no effects ontotal assets or total liabilities from applying the New Accounting Standards to the balance sheet as of March 31, 2006.

The adoption of the New Accounting Standards had no impacts on the consolidated statement of income for the year ended March 31,2007. Also, if the New Accounting Standards had not been adopted at March 31, 2007, the shareholders’ equity amounting to ¥81,307million ($688,751 thousand) would have been presented.

q. Accounting Standard for Statement of Changes in Net Assets – Effective from the year ended March 31, 2007, the Company and itsconsolidated subsidiaries adopted the new accounting standard, “Accounting Standard for Statement of Changes in Net Assets”(Statement No.6 issued by the Accounting Standards Board of Japan on December 27, 2005), and the implementation guidance for theaccounting standard for statement of changes in net assets (the Financial Accounting Standard Implementation Guidance No. 9 issuedby the Accounting Standards Board of Japan on December 27, 2005), (collectively, the “Additional New Accounting Standards”).

Accordingly, the Company prepared the statements of changes in net assets for the year ended March 31, 2007 in accordance with theAdditional New Accounting Standards. Also, the Company voluntarily prepared the consolidated statement of changes in net assets for2006 in accordance with the Additional New Accounting Standards. Previously, consolidated statements of shareholders’ equity wereprepared for the purpose of inclusion in the consolidated financial statements although such statements were not required underJapanese GAAP.

r. Bonuses to Directors – Effective from the year ended March 31, 2007, the Company and its consolidated domestic subsidiariesadopted the new accounting standard, “Accounting Standard for Directors’ Bonuses” (Statement No.4 issued by the AccountingStandards Board of Japan on November 29, 2005).

As a result of the adoption,selling, general and administrative expenses increased by negligible, thereby causing operating income and income before income taxesand minority interests to decreased by negligible, compared with the amounts that would have been recorded under the previousaccounting method.

10. NET ASSETSThe Japanese Corporate Law (“the Law”) became effective on May 1, 2006, replacing the Japanese Commercial Code (“the Code”). TheLaw is generally applicable to events and transactions occurring after April 30, 2006 and for fiscal years ending after that date.

Under Japanese laws and regulations, the entire amount paid for new shares is required to be designated as common stock. However,a company may, by a resolution of the Board of Directors, designate an amount not exceeding one-half of the price of the new shares asadditional paid-in capital, which is included in capital surplus.

Under the Law, in cases where a dividend distribution of surplus is made, the smaller of an amount equal to 10% of the dividend or theexcess, if any, of 25% of common stock over the total of additional paid-in-capital and legal earnings reserve must be set aside asadditional paid-in-capital or legal earnings reserve. Legal earnings reserve is included in retained earnings in the accompanyingconsolidated balance sheets.

Under the Code, companies were required to set aside an amount equal to at least 10% of the aggregate amount of cash dividendsand other cash appropriations as legal earnings reserve until the total of legal earnings reserve and additional paid-in capital equaled25% of common stock.

Under the Code, legal earnings reserve and additional paid-in capital could be used to eliminate or reduce a deficit by a resolution ofthe shareholders' meeting or could be capitalized by a resolution of the Board of Directors. Under the Law, both of these appropriationsgenerally require a resolution of the shareholders' meeting.

Additional paid-in capital and legal earnings reserve may not be distributed as dividends. Under the Code, however, on condition thatthe total amount of legal earnings reserve and additional paid-in capital remained equal to or exceeded 25% of common stock, they wereavailable for distribution by resolution of the shareholders’ meeting. Under the Law, all additional paid-in-capital and all legal earningsreserve may be transferred to other capital surplus and retained earnings, respectively, which are potentially available for dividends.

The maximum amount that the Company can distribute as dividends is calculated based on the non-consolidated financial statementsof the Company in accordance with Japanese laws and regulations.

At the general shareholders’ meeting held on June 22, 2007, the shareholders approved cash dividends amounting to ¥16,970 million($143,753 thousand). Such appropriations have not been accrued in the consolidated financial statement as of March 31, 2007. Suchappropriations are recognized in the period in which they are approved by the shareholders. The special taxation measures law andcorporate tax law permit companies to take as tax deductions certain reserves if provided through appropriation of retained earnings.Under Japanese tax laws, these reserves must be reversed to taxable income in future years. These reserves, included in retainedearnings at March 31, 2007 and 2006, were as follows:

To the Shareholders and Board of Directors of DISCO CORPORATION:

We have audited the accompanying consolidated balance sheets of DISCO CORPORATION and consolidated

subsidiaries as of March 31, 2007 and 2006, and the related consolidated statements of income, changes in net

assets and cash flows for the years then ended, expressed in Japanese yen. These consolidated financial statements

are the responsibility of the Company’s management. Our responsibility is to independently express an opinion on

these consolidated financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in Japan. Those standards

require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are

free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and

disclosures in the financial statements. An audit also includes assessing the accounting principles used and

significant estimates made by management, as well as evaluating the overall financial statement presentation. We

believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the

consolidated financial position of DISCO CORPORATION and subsidiaries as of March 31, 2007 and 2006, and the

consolidated results of their operations and their cash flows for the years then ended, in conformity with accounting

principles generally accepted in Japan.

The U.S. dollar amounts in the accompanying consolidated financial statements with respect to the year ended March

31, 2007 are presented solely for convenience. Our audit also included the translation of yen amounts into U.S. dollar

amounts and, in our opinion, such translation has been made on the basis described in Note 3 to the consolidated

financial statements.
