The accounting impact of these renovation payments increases both cash flow from operations and capital expenditures (investing activities) by the same amount and as a result has no net impact on Free Cash Flow.

Glossary Non-GAAP Financial Measures Investors are cautioned that Normalized EBITDA and Free Cash Flow are not financial measures under generally accepted accounting principles. In addition, they should not be construed as alternatives to any other measures of performance determined in accordance with generally accepted accounting principles. These non-GAAP financial measures are provided to enhance the user’s overall understanding of the Company’s current financial performance and the Company’s prospects for the future. Normalized EBITDA: Represents operating income excluding depreciation, accretion on obligations related to excess facilities, amortization, stock based compensation expense, Acquisition Adjustments, and Other charges. We believe Normalized EBITDA is an important measure of our recurring operations as it excludes items that may not be indicative of our core operating results. Reconciliation of Normalized EBITDA to GAAP

Glossary on-GAAP Financial Measures ree Cash Flow: Represents cash provided by operating activities excluding cash charges related to the acquisitions of AMR Research and Burton Group, which primarily consist of certain non-recurring costs such as severance and other exit costs (“Cash Acquisition and Integration Charges”), less additions to property, equipment and leasehold improvements (“Capital Expenditures”). We believe that Free Cash Flow is an important measure of the recurring cash generated by the Company’s core operations that is available to be used to repurchase stock, repay debt obligations and invest in future growth through new business development activities or acquisitions. Reconciliation of Free Cash Flow to GAAP
