Non-GAAP results are presented only as a supplement to the financial statements based on U.S. generally accepted accounting principles (GAAP). The non-GAAP financial information is provided to enhance the reader's understanding of our financial performance, but no non-GAAP measure should be considered in isolation or as a substitute for financial measures calculated in accordance with GAAP. Reconciliations of the most directly comparable GAAP measures to non-GAAP measures, such as Adjusted EBITDA and Adjusted earnings per diluted share, are provided with the schedules to our quarterly earnings releases. Our most recent non-GAAP reconciliations were furnished as an exhibit to a Form 8-K on June 18, 2012, and are available on our website ( www.ihs.com).

EBITDA is defined as net income plus or minus net interest plus income taxes, depreciation and amortization. Adjusted EBITDA further excludes (i) non-cash items (e.g., stock-based compensation expense and non-cash pension and postretirement expense) and (ii) items that management does not consider to be useful in assessing our operating performance (e.g., acquisition-related costs, restructuring charges, income or loss from discontinued operations, and gain or loss on sale of assets). Adjusted earnings per diluted share exclude similar items as Adjusted EBITDA. None of these non-GAAP financial measures are recognized terms under GAAP and do not purport to be an alternative to net income as an indicator of operating performance or any other GAAP measure.

Management uses these non-GAAP measures in its operational and financial decision-making, believing that it is useful to eliminate certain items in order to focus on what it deems to be a more reliable indicator of ongoing operating performance and our ability to generate cash flow from operations. As a result, internal management reports used during monthly operating reviews feature the Adjusted EBITDA and Adjusted earnings per diluted share metrics. Management also believes that investors may find non-GAAP financial measures useful for the same reasons, although investors are cautioned that non-GAAP financial measures are not a substitute for GAAP disclosures. EBITDA, Adjusted EBITDA, and Adjusted earnings per diluted share are also used by many of our investors, research analysts, investment bankers, and lenders to assess our operating performance. For example, a measure similar to Adjusted EBITDA is required by the lenders under our term loan and revolving credit agreement.

Because not all companies use identical calculations, our presentation of non-GAAP financial measures may not be comparable to other similarly-titled measures of other companies. However, these measures can still be useful in evaluating our performance against our peer companies because management believes the measures provide users with valuable insight into key components of GAAP financial disclosures. For example, a company with greater GAAP net income may not be as appealing to investors if its net income is more heavily comprised of gains on asset sales. Likewise, eliminating the effects of interest income and expense moderates the impact of a company's capital structure on its performance.

All of the items included in the reconciliation from net income to Adjusted EBITDA are either (i) non-cash items (e.g., depreciation and amortization, stock-based compensation, non-cash pension and postretirement expense) or (ii) items that we do not consider to be useful in assessing our operating performance (e.g., income taxes, acquisition-related costs, restructuring charges, income or loss from discontinued operations, and gain or loss on sale of assets). In the case of the non-cash items, management believes that investors can better assess our operating performance if the measures are presented without such items because, unlike cash expenses, these adjustments do not affect our ability to generate free cash flow or invest in our business. For example, by eliminating depreciation and amortization from EBITDA, users can compare operating performance without regard to different accounting determinations such as useful life. In the case of the other items, management believes that investors can better assess operating performance if the measures are presented without these items because their financial impact does not reflect ongoing operating performance.
