Such forward-looking statements are subject to the safe harbor created by the Private Securities Litigation Reform Act of 1995. When used in this document and in the documents incorporated herein by reference, the words “anticipate,” “believe,” “estimate,” “expect” and similar expressions, as they relate to the Company or its management, identify such forward-looking statements. Such statements reflect the current views of the Company or its management with respect to future events and are subject to certain risks, uncertainties and assumptions. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, the Company’s actual results, performance, or achievements could differ materially from those expressed in, or implied by, any such forward-looking statements. Factors that could cause or contribute to such material differences include the possibility that the demand for our services may decline as a result of changes in general and industry specific economic conditions, the timing of engagements for our services, the effects of competitive services and pricing, the absence of backlog related to our business, our ability to attract and retain key employees, the effect of tort reform and government regulation on our business, and liabilities resulting from claims made against us.

(1) EBITDAS is a non-GAAP financial measure defined by the Company as net income before income taxes, interest income, depreciation and amortization, and stock-based compensation. The Company regards EBITDAS as a useful measure of operating performance and cash flow to complement operating income, net income and other

GAAP financial performance measures. Additionally, management believes that EBITDAS provides meaningful comparisons of past, present and future operating results. Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position or cash flow that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. This measure, however, should be considered in addition to, and not as a substitute or superior to, operating income, cash flows, or other measures of financial performance prepared in accordance with GAAP. A reconciliation of EBITDAS to GAAP is set forth below.
