(1)

We have short-term investments in fixed-income securities, including U.S. Treasury and U.S. agency securities. We measure the fair value of U.S. Treasury securities using quoted prices for identical assets in active markets. We measure the fair value of U.S. agency securities using observable market activity for similar assets. The fair value of our fixed-income securities approximates our cost basis in the investments.

(2)

We invest portions of our Cash and cash equivalents and Restricted cash and investments in money market funds. We measure the fair value of these money market fund investments using quoted prices for identical assets in active markets. The portion of Restricted cash and investments that is invested in money market funds is considered restricted cash for purposes of reconciling the beginning-of-year and end-of-year amounts presented in the Company’s consolidated statements of cash flows.

In order to manage interest rate exposure, we entered into an interest rate swap agreement in March 2020 and October 2014 that effectively converts a portion of our variable-rate debt to a fixed interest rate. In connection with our entry into the March 2020 interest rate swap, we terminated the October 2014 interest rate swap prior to its scheduled maturity date of June 2021. The March 2020 interest rate swap is designated as a highly-effective cash flow hedge,

with gains and losses deferred in other comprehensive income to be recognized as an adjustment to interest expense in the same period that the hedged interest payments affect earnings. The October 2014 interest rate swap was also designated as a highly effective cash flow hedge. The March 2020 interest rate swap has an effective date of March 31, 2020 in an initial notional amount of $500.0 million. The fair value of the interest rate swap agreement represents the difference in the present value of cash flows calculated (i) at the contracted interest rates and (ii) at current market interest rates at the end of the period. We calculate the fair value of interest rate swap agreements quarterly based on the quoted market price for the same or similar financial instruments. The fair value of the interest rate swap agreements are included in Other assets and Other long-term liabilities in the Company’s consolidated balance sheets as of December 31, 2021 and 2020, respectively.

Our contingent consideration liabilities represent the estimated fair value of potential future payments the Company may be required to remit under the terms of historical purchase agreements entered into by NRC prior to the NRC Merger. The payments are contingent on the acquired businesses’ achievement of annual earnings targets in certain years and other events considered in the purchase agreements. The fair value of our contingent consideration liabilities is calculated using either a Monte Carlo simulation or modified Black-Scholes analyses based on earnings projections for the respective earn-out periods, corresponding earnings thresholds, and approximate timing of payments as outlined in the purchase agreements. The analyses utilize the following assumptions: (i) expected term; (ii) risk-adjusted net sales or earnings; (iii) risk-free interest rate; and (iv) expected volatility of earnings. Estimated payments, as determined through the respective models, are discounted by a credit spread assumption to account for credit risk. As of December 30, 2021, we have settled all acquired contingent consideration liabilities associated with the NRC Merger. The fair value of our contingent consideration liability as of December 31, 2020 was $2.2 million and is included in Accrued liabilities in the Company’s consolidated balance sheet. We revalue our contingent consideration payments each period and any increases or decreases to fair value are included in Selling, general and administrative expenses in our consolidated statements of operations. Fair values may be impacted by certain unobservable inputs, most significantly with regard to discount rates, expected volatility and historical and projected performance. Significant changes to these inputs in isolation could result in a significantly different fair value measurement.
