Non-GAAP Financial Measures

Normalized EBITDA: Represents operating income excluding depreciation, accretion on obligations related to excess facilities, amortization, stock-based compensation expense, and acquisition-related 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. Investors are cautioned that Normalized EBITDA is not a financial measure defined under generally accepted accounting principles and as a result is considered a non-GAAP financial measure. We provide this measure to enhance the user’s overall understanding of the Company’s current financial performance and the Company’s prospects for the future. It should not be construed as an alternative to any other measure of performance determined in accordance with generally accepted accounting principles.

Free Cash Flow: Represents cash provided by operating activities plus cash acquisition and integration payments 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.
