​ The fair value of CRA’s money market mutual fund share holdings is $1.00 per share. The contingent consideration liability in the table above is for estimated future contingent consideration payments related to the acquisition of C1 Consulting, LLC, an independent consulting firm, and its wholly-owned subsidiary C1 Associates (collectively, “C1”). The fair value measurement of the liability is based on significant inputs not observed in the market and thus represents a Level 3 measurement. The significant unobservable inputs used in the fair value measurement of the contingent consideration liability are CRA’s measures of the estimated payouts based on internally generated revenue projections, expected volatility of the revenue projections, and discount rates. The fair value of the contingent consideration liability had been determined using a Monte Carlo simulation in prior fiscal quarters. In the current fiscal quarter, the fair value was estimated using an accrual method that approximates the fair value, as the end of the measurement period occurs during the first quarter of fiscal 2021. The fair value of the contingent consideration liability is reassessed on a quarterly basis by CRA using additional information as it becomes available, and any change in the fair value estimates are recorded in costs of services (exclusive of depreciation and amortization) on the condensed consolidated statements of operations. The contingent consideration is required to be paid prior to the end of the second quarter of fiscal 2021. The following table summarizes the changes in the contingent consideration liabilities (in thousands):
​ |  | Fiscal Year-to-Date Period Ended |  | Fiscal Year Ended

Beginning balance |  | $ | 11,579 |  |  | $ | 6,197 |
Remeasurement of acquisition-related contingent consideration |  | 921 |  |  | 3,285 |
