Non-GAAP financial measures and reconciliations

To supplement our financial results presented on a GAAP basis, we provide investors with certain non-GAAP financial measures, including gross billings, recurring billings, non-GAAP revenue, non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating loss, non-GAAP operating margin, non-GAAP net loss, and non-GAAP net loss per share. These non-GAAP financial measures exclude stock-based compensation, the amortization of intangible assets, the impairment of in-process research and development, and perpetual license revenue recognized from licenses delivered prior to 2013:

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, operating margin, net loss, and net loss per share. 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 prior to 2013. 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.

Stock-based compensation expenses: We have excluded the effect of stock-based compensation expenses from our gross profit, gross margin, operating loss, operating margin, net loss, and net loss per share. 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 gross profit, gross margin, operating loss, operating margin, net loss, and net loss per share. Amortization of intangible assets is significantly affected by the timing and size of our acquisitions. Amortization of intangible assets will recur in future periods.

Impairment of in-process research and development: We have excluded the effect of the impairment of in-process research and development from our operating loss, operating margin, net loss, and net loss per share.  This impairment expense is not expected to recur.

Non-GAAP revenue, non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating loss, non-GAAP operating margin, non-GAAP net loss, and non-GAAP net loss per share: We believe that the exclusion of perpetual license revenue recognized from licenses delivered prior to 2013, stock-based compensation expense, amortization of intangible assets and the impairment of in-process research and development, as relevant, from revenue, gross profit, gross margin, operating loss, operating margin, net loss, and net loss per share provides useful measures for management and investors because revenue recognized from licenses delivered prior to 2013 has and will continue to significantly decline over time until it is fully amortized and stock-based compensation, the amortization of intangible assets and the impairment of in-process research and development have been and can continue to be inconsistent in amount from period to period. We believe the inclusion of these items makes it difficult to compare periods and understand the growth and performance of our business. In addition, we evaluate our business performance and compensate management based on these non-GAAP measures. There are limitations in using non-GAAP financial measures because the non-GAAP financial measures are not prepared in accordance with GAAP, may be different from non-GAAP financial measures used by our competitors and exclude expenses that may have a material impact upon our reported financial results. Further, stock-based compensation expense has been and will continue to be for the foreseeable future a significant recurring expense in our business and an important part of the compensation provided to our employees. Similarly, amortization of intangible assets has been and will continue to be a recurring expense and has and will continue to contribute to our revenue earned.

Gross and recurring billings and free cash flow:  Our non-GAAP financial measures also include:  gross billings, which we define as total revenue plus the change in deferred revenue in a period; recurring billings, which we define as total revenue less perpetual license, hardware, and professional services revenue plus the change in deferred revenue for subscription and software support arrangements in a period, adjusted for nonrecurring perpetual license billings; and free cash flow, which we define as cash used in operating activities less the amount of the purchase of property and equipment. We consider gross billings to be a useful metric for management and investors because gross billings drive deferred revenue, which is an important indicator of the health and visibility of our business. Similarly, we consider recurring billings to be a useful metric because recurring billings drive software support and subscription deferred revenue, which is an important indicator of the portion of our business that we would expect to recur each year. There are a number of limitations related to the use of gross and recurring billings versus revenue calculated in accordance with GAAP. First, gross and recurring billings include amounts that have not yet been recognized as revenue. Second, our calculation of gross and recurring billings may be different from other companies that report similar financial measures. We compensate for these limitations by providing specific information regarding GAAP revenue and evaluating gross and recurring billings together with revenue calculated in accordance with GAAP. Management believes that information regarding free cash flow provides investors with an important perspective on the cash available to invest in our business and fund ongoing operations. However, our calculation of free cash flow may not be comparable to similar measures used by other companies.

We believe these non-GAAP financial measures 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 certain of these non-GAAP measures.
