(6) Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The authoritative guidance for fair value measurements establishes a three-level fair value hierarchy that encourages an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of inputs used to measure fair value are as follows:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets.

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities, including certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

As of October 1, 2022 and October 2, 2021, we held financial assets that are required to be measured at fair value on a recurring basis, which are summarized below:

Cash equivalents, which include all highly liquid investments with original maturities of three months or less, are classified as Level 1 of the fair value hierarchy. The carrying amount of our cash equivalents, which consist of investments in money market funds, approximates fair value due to their short maturities. Cash surrender value of life insurance policies are classified as Level 2. The fair value of the life insurance policies was determined by the underwriting insurance company’s valuation models and represents the guaranteed value we would receive upon surrender of these policies as of the reporting date.

As of October 1, 2022 and October 2, 2021, we had no nonfinancial assets that are required to be measured at fair value on a nonrecurring basis. During 2021, we recognized $1.4 million of impairment charges related to the Summerville facility acquired in the STM Acquisition to reflect its fair value of $6.3 million as of October 2, 2021. The Summerville facility, which was sold in 2022, was classified as assets held for sale in other assets on our consolidated balance sheet as of October 2, 2021. The carrying amounts of accounts receivable, accounts payable and accrued expenses approximate fair value due to the short-term maturities of these financial instruments.
