Use of Non-GAAP Financial Measures
This press release includes financial measures for net income and net income per share that exclude certain non-cash charges and that have not been calculated in accordance with GAAP. These measures differ from GAAP in that they exclude the amortization of intangible assets from acquisitions and stock-based compensation for stock options granted prior to Synplicity's initial public offering. Synplicity has previously provided these measurements in addition to GAAP financial results because it believes they provide a consistent basis for comparison between quarters that is not influenced by certain non-cash activity and therefore are helpful to understanding Synplicity's underlying operational results. Further, these non-GAAP measures are some of the primary measures Synplicity's management uses for planning and forecasting. These measures should not be considered an alternative to GAAP, and these non-GAAP measures may not be comparable to information provided by other companies.
