Management typically excludes the amounts described above when evaluating the Company’s operating performance and believes that the resulting non-GAAP measures are useful to investors and financial analysts in assessing the Company’s operating performance due to the following factors:
- Amortization of Acquired Intangibles. Amortization costs and the related tax effects are fixed at the time of an acquisition, and then amortized over a period of several years after the acquisition and generally cannot be changed or influenced by management after the acquisition.
- Stock-based Compensation. Although stock-based compensation is an important aspect of compensation of the Company’s employees and executives, stock-based compensation expense is generally fixed at the time of grant, then amortized over a period of several years after the grant of the stock-based instrument, and generally cannot be changed or influenced by management after the grant. In addition, the impact of shares granted under these plans is considered in the Company’s EPS calculation to the extent the shares are dilutive.
- Bookings. Although revenue is an important aspect of measuring Company performance, the Company believes total sales bookings can be a valuable indicator of the Company's performance. The Company is transitioning to a greater amount of subscription sales, which results in an increasing portion of sales being recorded as deferred revenue.
