© comScore, Inc. Proprietary. 4 Use of Non-GAAP Measures comScore reports all financial information required in accordance with generally accepted accounting principles (GAAP). comScore believes, however, that evaluating its ongoing operating results will be enhanced if it also discloses certain non-GAAP information because it is useful to understand comScore's performance, as it excludes non-cash and other charges that many investors believe may obscure comScore's on-going operating results. For example, comScore uses non-GAAP net income, which excludes stock-based compensation, amortization of acquired intangible assets, impairment of intangible assets, impairment of marketable securities, costs from acquisitions, restructurings and other infrequently occurring items, non-cash deferred tax provision and litigation and related settlement costs. comScore reports non-GAAP EPS (diluted), which uses non-GAAP net income in lieu of GAAP net income in calculating earnings per share. Year to date 2015 and 2014 Non-GAAP pro forma revenue excludes the estimated effects of revenue generated from the mobile operator analytics division. Year to date 2015 and 2014 adjusted pro forma EBITDA also excludes the estimated effects of operations related to the mobile operator analytics division products. The company believes that excluding certain costs from non-GAAP net income, non-GAAP EPS, and adjusted EBITDA provides a meaningful indication to investors of the expected on-going operating performance of the company. Specifically as it relates to acquisitions and restructurings, the exclusion of these costs reflects the expected benefits realized or to be realized upon the integration of acquired entities into comScore, and the realized benefits of the restructurings. Whenever comScore uses such historical non-GAAP financial measures, it provides a reconciliation of historical non-GAAP financial measures to the most closely applicable GAAP financial measure. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these historical non-GAAP financial measures to their most directly comparable GAAP financial measure included in the financial tables accompanying this release. Although the company provides a reconciliation of historical non-GAAP financial measures, due to the high variability and difficulty in predicting certain items that affect net income, such as tax rates and stock price, comScore is unable to provide a complete reconciliation of adjusted EBITDA to net income on a forward-looking basis without unreasonable efforts. However, a reconciliation of forward-looking adjusted EBITDA to GAAP income (loss) before income taxes is set forth in the attachment to comScore’s August 4, 2015 earnings press release, which is available under the “Investor Relations” section of the comScore’s website at These non-GAAP financial measures do not reflect a comprehensive system of accounting, differ from GAAP measures with the same captions and may differ from non-GAAP financial measures with the same or similar captions that are used by other companies. The use of certain non-GAAP financial measures requires management to make estimates and assumptions regarding amounts of assets and liabilities and the amounts of revenue and expense during the reporting periods. comScore bases its estimates on historical experience and assumptions that it believes are reasonable. Actual results could differ from those estimates.
