		(In thousands)
Assets:

(1) The fair values of the money market funds were based on recently quoted market prices and reported transactions in an active marketplace. Money market funds are included on the Company's Consolidated Balance Sheets in "Cash and cash equivalents."

(2) The contingent earnout liability relates to businesses acquired since 2020. See Note 3, "Business Acquisitions and Dispositions" for more information. The Level 3 fair value of the contingent earnout liability was estimated using revenue and EBITDA projections, and discount rates determined using a combination of observable and unobservable market data as well as volatility assumptions as applicable. The Company recognized a pretax contingent earnout expense totaling $4,025,000 in 2023 and $2,921,000 in 2022 related to the fair value adjustment of earnout liabilities arising from recent acquisitions. The fair value of the contingent earnout liability is included in "Other accrued liabilities" and "Other noncurrent liabilities" on the Company's Consolidated Balance Sheets, based upon the term of the contingent earnout agreement.
