During the three fiscal months ended April 2, 2022, the liabilities for unrecognized tax benefits decreased by $3,047 on a net basis, primarily due to a payment and currency translation adjustments, partially offset by accruals for current year tax positions and interest.

Fair Value Measurements	Note 12 – Fair Value Measurements The following table provides the financial assets and liabilities carried at fair value measured on a recurring basis: Total Fair Value Level 1 Level 2 Level 3 April 2, 2022 Assets: Assets held in rabbi trusts $ 53,881 $ 28,280 $ 25,601 $ - Available for sale securities $ 4,165 4,165 - - Precious metals $ 5,666 5,666 - - $ 63,712 $ 38,111 $ 25,601 $ - December 31, 2021 Assets: Assets held in rabbi trusts $ 59,687 $ 32,713 26,974 $ - Available for sale securities $ 4,455 4,455 - - $ 64,142 $ 37,168 $ 26,974 $ - There have been no changes in the classification of any financial instruments within the fair value hierarchy in the periods presented. The Company maintains non-qualified trusts, referred to as “rabbi” trusts, to fund payments under deferred compensation and non-qualified pension plans. Rabbi trust assets consist primarily of marketable securities, classified as available-for-sale and company-owned life insurance assets. The marketable securities held in the rabbi trusts are valued using quoted market prices on the last business day of the period. The company-owned life insurance assets are valued in consultation with the Company’s insurance brokers using the value of underlying assets of the insurance contracts. The fair value measurement of the marketable securities held in the rabbi trust is considered a Level 1 measurement and the measurement of the company-owned life insurance assets is considered a Level 2 measurement within the fair value hierarchy. The Company holds investments in debt securities that are intended to fund a portion of its pension and other postretirement benefit obligations outside of the United States. The investments are valued based on quoted market prices on the last business day of the period. The fair value measurement of the investments is considered a Level 1 measurement within the fair value hierarchy. From time to time, the Company purchases precious metals bullion in excess of its immediate manufacturing needs to mitigate the risk of supply shortages or volatile price fluctuations. The metals are valued based on quoted market prices on the last business day of the period. The fair value measurement of the metals are considered a Level 1 measurement within the fair value hierarchy. The Company enters into forward contracts with highly-rated financial institutions to mitigate the foreign currency risk associated with intercompany loans denominated in a currency other than the legal entity's functional currency. The notional amount of the forward contracts was $80,000 and $100,000 as of April 2, 2022 and December 31, 2021, respectively. The forward contracts are short-term in nature and are expected to be renewed at the Company's discretion until the intercompany loans are repaid. We have not designated the forward contracts as hedges for accounting purposes, and as such the change in the fair value of the contracts is recognized in the consolidated condensed statements of operations as a component of other income (expense). The Company estimates the fair value of the forward contracts based on applicable and commonly used pricing models using current market information and is considered a Level 2 measurement within the fair value hierarchy. The value of the forward contracts was immaterial as of April 2, 2022 and December 31, 2021. The Company does not utilize derivatives or other financial instruments for trading or other speculative purposes. The fair value of the long-term debt, excluding the derivative liabilities and deferred financing costs, at April 2, 2022 and December 31, 2021 is approximately $463,800 and $485,500, respectively, compared to its carrying value, excluding the deferred financing costs, of $465,344. The Company estimates the fair value of its long-term debt using a combination of quoted market prices for similar financing arrangements and expected future payments discounted at risk-adjusted rates, which are considered Level 2 inputs. At April 2, 2022 and December 31, 2021, the Company’s short-term investments were comprised of time deposits with financial institutions that have maturities that exceed 90 days from the date of acquisition; however they all mature within one year from the respective balance sheet dates. The Company's short-term investments are accounted for as held-to-maturity debt instruments, at amortized cost, which approximates their fair value. The investments are funded with excess cash not expected to be needed for operations prior to maturity; therefore, the Company believes it has the intent and ability to hold the short-term investments until maturity. At each reporting date, the Company performs an evaluation to determine if any unrealized losses are other-than-temporary. No other-than-temporary impairments have been recognized on these securities, and there are no unrecognized holding gains or losses for these securities during the periods presented. There have been no transfers to or from the held-to-maturity classification. All decreases in the account balance are due to returns of principal at the securities’ maturity dates. Interest on the securities is recognized as interest income when earned. At April 2, 2022 and December 31, 2021, the Company’s cash and cash equivalents were comprised of demand deposits, time deposits with maturities of three months or less when purchased, and money market funds. The Company estimates the fair value of its cash, cash equivalents, and short-term investments using level 2 inputs. Based on the current interest rates for similar investments with comparable credit risk and time to maturity, the fair value of the Company's cash, cash equivalents, and held-to-maturity short-term investments approximate the carrying amounts reported in the consolidated condensed balance sheets. The Company’s financial instruments also include accounts receivable and accounts payable. The carrying amounts for these financial instruments reported in the consolidated condensed balance sheets approximate their fair values.
