The fair values of cash and cash equivalents and restricted cash approximate the carrying values. The Company determines the fair value of its debt securities based on indicative, non-binding quotes from brokers. Quotes from brokers require judgment and are based on the brokers' interpretation of market information, including implied credit spreads for similar borrowings on recent trades or bid/ask prices or quotes from active markets if available. Since December 31, 2022, there have been no changes in the Company's valuation techniques used to measure fair values.
