Estimates in these consolidated financial statements include, but are not limited to, allowances for accounts receivable and unbilled services, revenue recognition on fixed-price contracts, variable consideration to be included in the transaction price of revenue contracts, the useful life of long-lived assets, measurement of operating lease right-of-use ("ROU") assets and liabilities, share-based compensation, valuation of contingent consideration liabilities, valuation of acquired intangible assets, goodwill, accrued and deferred income taxes, valuation allowances on deferred tax assets, accrued incentive compensation, and certain other accrued expenses. These items are monitored and analyzed by CRA for changes in facts and circumstances, and material changes in these estimates could occur in the future. Changes in estimates are recorded in the period in which they become known. CRA bases its estimates on historical experience and various other assumptions that CRA believes to be reasonable under the circumstances. Actual results may differ from those estimates if CRA's assumptions based on past experience or other assumptions do not turn out to be substantially accurate.</span></div>

At times, these deposits may exceed federally insured limits. As of December 31, 2022, CRA's cash accounts were concentrated at two financial institutions, which potentially exposes CRA to credit risks. The financial institutions have short-term credit ratings of A-1 and A-2 by Standard & Poor's ratings services. CRA has not experienced any losses related to such accounts. CRA does not believe that there is significant risk of non-performance by the financial institutions, and its cash on deposit is fully liquid.
