On February 11, 2009, Forrester Research, Inc. issued a press release announcing its financial results for the quarter and year ended December 31, 2008.
Forrester believes that pro forma financial results provide investors with consistent and comparable information to aid in the understanding of Forrester's ongoing business. Forrester uses pro forma financial information to manage its business, including use of pro forma financial results as the basis for setting targets for various compensation programs. Our pro forma presentation excludes the following, as well as their related tax effects:
Amortization of intangibles-we exclude the effect of the amortization of intangibles from our pro forma results in order to more consistently present our ongoing results of operations.
Impairments of and gains related to non-marketable securities and gains from sales of marketable securities-we have consistently excluded both one-time gains and one-time write-offs related to our investments in non-marketable securities and sales of marketable securities from our pro forma results in order to keep quarter-over-quarter and year-over-year comparisons consistent.
Stock-based compensation expense-we exclude the stock-based compensation impact of SFAS 123R from our pro forma results in order to keep quarter-over-quarter and year-over-year comparisons consistent.
Expenses related to the Company's stock option investigation and the restatement of the Company's historical financial statements are also not included in our pro forma results in order to keep quarter-over-quarter and year-over year comparisons consistent.
However, these measures should be considered in addition to, not as a substitute for, or superior to, operating income or other measures of financial performance prepared in accordance with generally accepted accounting principles as more fully discussed in our financial statements and filings with the Securities and Exchange Commission.
