GAAP to Non-GAAP ReconciliationExplanation of Non-GAAP Measures

To supplement our financial results presented on a GAAP basis, we use the non-GAAP measures indicated in the tables, which exclude stock-based compensation, the amortization of intangible assets, and perpetual revenue recognized from licenses delivered prior to 2013, that we believe are helpful in understanding our past financial performance and our future results. Our non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP measures and should be read only in conjunction with our consolidated financial statements prepared in accordance with GAAP. Our management regularly uses our supplemental non-GAAP financial measures internally to understand, manage and evaluate our business and make operating decisions. These non-GAAP measures are among the primary factors management uses in planning for and forecasting future periods. Compensation of our executives is based in part on the performance of our business based on these non-GAAP measures. Our non-GAAP financial measures reflect adjustments based on the following items:

Perpetual license revenue recognized from licenses delivered prior to 2013 We have excluded the effect of perpetual license revenue recognized from licenses delivered prior to 2013 from revenue gross profit, gross margin, operating loss, and operating margin. Because we had not established vendor specific objective evidence, or VSOE, of fair value of software support and services prior to January 1, 2013, we recognized perpetual license revenue ratably over the term of the related software support agreement. Upon establishing VSOE on January 1, 2013, we began to recognize perpetual license revenue upon delivery assuming all other revenue recognition criteria are met. As a result, our perpetual license revenue includes amounts related to licenses delivered in previous years. Revenue from these perpetual licenses delivered prior to 2013 has declined over each quarter since the quarter ended March 31, 2013 and will continue to decline sequentially until it is fully amortized. We evaluate our business performance excluding revenue from these perpetual licenses delivered prior to 2013 as we believe that the inclusion of this revenue makes it difficult to compare periods and understand growth in our business.

Stock-based compensation expenses: We have excluded the effect of stock-based compensation expenses from our non-GAAP cost of revenue, operating expenses and net income measures. Although stock-based compensation is a key incentive offered to our employees, and we believe such compensation contributed to the revenues earned during the periods presented and also believe it will contribute to the generation of future period revenues, we continue to evaluate our business performance excluding stock-based compensation expenses. Stock-based compensation expenses will recur in future periods.

Amortization of intangible assets: We have excluded the effect of amortization of intangible assets from our non-GAAP cost of revenue, operating expenses and netincome measures. Amortization of intangible assets is inconsistent in amount and frequency and is significantly affected by the timing and size of our acquisitions. Investors should note that the use of intangible assets contributed to our revenues earned during the periods presented and will contribute to our future period revenues as well. Amortization of intangible assets will recur in future periods.

Restructuring Charges: In our non-GAAP financial measures, we have excluded the effect of the severance and other expenses related to our reduction in workforce. Restructuring charges may recur in the future; however, the timing and amounts are difficult to predict.
