Investments, Debt and Equity Securities [Abstract] |
Short-term Investments | Short-term Investments The Company invests certain of its excess cash in short-term debt instruments which consist of U.S. Treasury bills with original maturities greater than three months and less than one year. All short-term investments are classified as held-to-maturity and are recorded and held at amortized cost. Investments are considered to be impaired when a decline in fair value is deemed to be other-than-temporary. Once a decline in fair value is determined to be other-than-temporary, the carrying value of an instrument is adjusted to its fair value on a non-recurring basis. No such fair value impairment was recognized during the three months ended March 31, 2023 and year ended December 31, 2022. The following tables summarize the Company's financial instruments that were measured at fair value on a non-recurring basis (in thousands):
