[1] The Company’s money market investments are included in cash and cash equivalents and the value considers the liquidity of the counterparty.
[2]
The Company’s investments in marketable equity securities are held in common shares of U.S. and non-U.S. corporations that are actively traded on U.S. and non-U.S. stock exchanges. Price quotes for these shares are readily available.
[3] Includes mutual funds, which are valued using a market approach based on the quoted market prices of the security or inputs that include quoted market prices for similar instruments.
[4] Included in Accounts payable, vehicle floor plan payable and accrued liabilities and Other Liabilities. The Company determined the fair value of the contingent consideration liabilities using either a Monte Carlo simulation, Black-Scholes model, or probability-weighted analysis depending on the type of target included in the contingent consideration requirements (revenue, EBITDA, client retention). All analyses included estimated financial projections for the acquired businesses and acquisition-specific discount rates.
[5] Included in Other Liabilities. The Company utilized a market approach model using the notional amount of the interest rate swaps multiplied by the observable inputs of time to maturity and market interest rates.
[6] The fair value of the mandatorily redeemable noncontrolling interest is based on the fair value of the underlying subsidiaries owned by GHC One and GHC Two, after taking into account any debt and other noncontrolling interests of its subsidiary investments. The fair value of the owned subsidiaries is determined using enterprise value analyses which include an equal weighing between guideline public company and discounted cash flow analyses.
