__________ (1) Quoted prices in active markets for identical assets. (2) Quoted prices for similar assets and liabilities in active markets. (3) Significant unobservable inputs. (4) Consists of a deferred compensation arrangement through which we hold various investment securities recognized on our balance sheets. Both the asset and liability related to investment securities are recorded at fair value and are included within "Other assets" and "Other liabilities" on the consolidated balance sheets, respectively. In addition to the investment securities, we also had company-owned life insurance related to the deferred compensation arrangement recorded at cash surrender value in "Other assets" of $13.3 million and $14.0 million at December 31, 2022 and 2021, respectively. (5) Included within "Other liabilities" on the consolidated balance sheet. Nonrecurring Fair Value Measurements There were no nonrecurring fair value measurements on the consolidated balance sheet during the year ended December 31, 2022 and 2021, respectively. Strategic Investments Equity Method Investments During 2021 and 2022, we acquired two separate strategic investments in privately-held companies for $16.5 million and $14.6 million, respectively, which are both accounted for under the equity method of accounting. The carrying value of our strategic equity investments was $28.2 million at December 31, 2022 and $16.5 million at December 31, 2021. There were no adjustments to the carrying value of equity method investments for impairment for the periods ended, December 31, 2022 and 2021. During 2022, we entered into an investment with a venture capital fund for $0.8 million, which is accounted for under the equity method of accounting. As of December 31, 2022 and 2021, respectively, we had approximately $6.7 million and zero of unfunded commitments, which we anticipate will be paid over a period of 10 years. The carrying value of our strategic equity investment was $0.7 million and zero at December 31, 2022 and 2021, respectively. Measurement Alternative Investments During 2022, we invested $62.0 million to acquire equity interests in two separate strategic investments, $60.0 million of which was our investment in lithium-ion anode materials producer, Nexeon Limited. Both of these investments are accounted for under the measurement alternative method. During 2021, we acquired two strategic investments in privately-held companies for $18.8 million. The aggregate carrying value of all measurement alternative investments where fair value is not readily determinable totaled $80.9 million and $18.8 million at December 31, 2022 and 2021, respectively. There were no adjustments to the carrying value of the measurement alternative method investments for impairment or observable price changes for the periods ended December 31, 2022 or 2021. Restricted Investment Our restricted investment is a trust managed in order to secure repayment of the finance lease obligation associated with Performance Materials' Wickliffe, Kentucky, manufacturing site at maturity. The trust, presented as a restricted investment on our consolidated balance sheets, purchased long-term bonds that mature in 2025 and 2026. The principal received at maturity of the bonds, along with interest income that is reinvested in the trust, are expected to be equal to or more than the $80.0 million finance lease obligation that is due in 2027. Because the provisions of the trust provide us the ability, and it is our intent, to hold the investments to maturity, the investments held by the trust are accounted for as held to maturity ("HTM"); therefore, they are held at their amortized cost. The investments held by the trust earn interest at the stated coupon rate of the invested bonds. Interest earned on the investments held by the trust is recognized as interest income and presented within interest income on our consolidated statement of operations. At December 31, 2022 and 2021, the carrying value of our restricted investment, which is accounted for as HTM and therefore held at amortized costs, was $78.0 million and $76.1 million, net of an allowance for credit losses of $0.6 million and $0.5 million and included cash of $7.0 million and $4.7 million, respectively. The fair value at December 31, 2022 and 2021 was $74.7 million and $80.0 million, respectively, based on Level 1 inputs. The following table shows the total amortized cost of our HTM debt securities by credit rating, excluding the allowance for credit losses and cash. The primary factor in our expected credit loss calculation is the composite bond rating. As the rating decreases, the risk present in holding the bond is inherently increased, leading to an increase in expected credit losses.

Debt and Finance Lease Obligations At December 31, 2022 and 2021, the carrying value of finance lease obligations was $101.9 million and $102.4 million, respectively, and the fair value was $106.2 million and $118.6 million, respectively. The fair value of our finance lease obligations is based on the period-end quoted market prices for the obligations, using Level 2 inputs. The fair value of all other finance lease obligations approximates their carrying values. The carrying value, excluding debt issuance fees, of our variable rate debt was $828.0 million and $328.1 million as of December 31, 2022 and 2021, respectively. The carrying value is a reasonable estimate of the fair value of our outstanding debt as our outstanding debt is variable interest rate debt. At December 31, 2022 and 2021, the carrying value of our fixed rate debt was $550.0 million and $850.0 million, respectively, and the fair value was $471.8 million and $843.9 million, respectively, based on Level 2 inputs. Contingent Consideration In connection with the acquisition of certain assets in 2020, we are contingently obligated to make an additional payment for such assets of up to an aggregate amount of $7.0 million. The contingent consideration is payable if certain sales volume targets are achieved prior to the expiration on December 31, 2024, therein referred to as "Revenue Earn-out." The fair value of the five-year Revenue Earn-out consideration was zero and $0.8 million at December 31, 2022 and 2021, respectively. Any changes in the fair value of the contingent consideration liability are recorded in current period earnings as a selling, general, and administrative expense.
