Fair Value Measurements

10. Fair Value Measurements

The following is a description of the valuation techniques that we use to measure the fair value of assets and liabilities that we measure and report at fair value on a recurring basis:

•Cash Equivalents and Restricted Cash Equivalents. At December 31, 2022, our cash equivalents and restricted cash equivalents consisted of money market funds. We value our cash equivalents and restricted cash equivalents using observable inputs that reflect quoted prices for securities with identical characteristics and classify the valuation techniques that use these inputs as Level 1.

•Marketable Securities and Restricted Marketable Securities. At December 31, 2022 and 2021, our marketable securities consisted of foreign debt, U.S. debt, and time deposits, and our restricted marketable securities consisted of foreign and U.S. government obligations, supranational debt, and U.S. debt. We value our marketable securities and restricted marketable securities using observable inputs that reflect quoted prices for securities with identical characteristics or quoted prices for securities with similar characteristics and other observable inputs (such as interest rates that are observable at commonly quoted intervals). Accordingly, we classify the valuation techniques that use these inputs as either Level 1 or Level 2 depending on the inputs used. We also consider the effect of our counterparties’ credit standing in these fair value measurements.

•Derivative Assets and Liabilities. At December 31, 2022 and 2021, our derivative assets and liabilities consisted of foreign exchange forward contracts involving major currencies. At December 31, 2022, our derivative assets and liabilities also consisted of commodity swap contracts involving major commodity prices. Since our derivative assets and liabilities are not traded on an exchange, we value them using standard industry valuation models. As applicable, these models project future cash flows and discount the amounts to a present value using market-based observable inputs, including credit risk, foreign exchange rates, forward and spot prices for currencies, and forward prices for commodities. These inputs are observable in active markets over the contract term of the derivative instruments we hold, and accordingly, we classify the valuation techniques as Level 2. In evaluating credit risk, we consider the effect of our counterparties’ and our own credit standing in the fair value measurements of our derivative assets and liabilities, respectively.

At December 31, 2022 and 2021, the fair value measurements of our assets and liabilities measured on a recurring basis were as follows (in thousands):

Fair Value of Financial Instruments

At December 31, 2022 and 2021, the carrying values and fair values of our financial instruments not measured at fair value were as follows (in thousands):

	December 31, 2022				December 31, 2021
	Carrying Value		Fair Value		Carrying Value		Fair Value
Assets:
Accounts receivable unbilled, net - noncurrent	$	11,498	$	10,304	$	20,840	$	18,846
Accounts receivable trade, net - noncurrent	1,500		1,339		21,293		18,605
Liabilities:
Long-term debt, including current maturities (1)	$	185,000	$	160,986	$	246,737	$	243,865

——————————

(1)Excludes unamortized discounts and issuance costs.

The carrying values in our consolidated balance sheets of our current trade accounts receivable, current unbilled accounts receivable, restricted cash, accounts payable, and accrued expenses approximated their fair values due to their nature and relatively short maturities; therefore, we excluded them from the foregoing table. The fair value measurements for our noncurrent unbilled accounts receivable, noncurrent trade accounts receivable, and long-term debt are considered Level 2 measurements under the fair value hierarchy.

Credit Risk

We have certain financial and derivative instruments that subject us to credit risk. These consist primarily of cash, cash equivalents, marketable securities, accounts receivable, restricted cash, restricted cash equivalents, restricted marketable securities, foreign exchange forward contracts, and commodity swap contracts. We are exposed to credit losses in the event of nonperformance by the counterparties to our financial and derivative instruments. We place these instruments with various high-quality financial institutions and limit the amount of credit risk from any one counterparty. We monitor the credit standing of our counterparty financial institutions. Our net sales are primarily concentrated among a limited number of customers. We monitor the financial condition of our customers and perform credit evaluations whenever considered necessary. We typically require some form of payment security from our customers, including, but not limited to, advance payments, parent guarantees, letters of credit, bank guarantees, or surety bonds.
