Investments | 4. Investments Investments, at fair value At both September 30, 2023 and December 31, 2022, we had $0.1 million of cash invested in highly liquid taxable bond funds. We classify these investments as trading securities and report them at fair value. There were no significant unrealized gains or losses on these investments in the three or nine months ended September 30, 2023 and 2022. The fair value measurements of these investments are based on quoted market prices in active markets, and thus represent a Level 1 valuation as defined by Accounting Standards Codification (“ASC”) 820, Fair Value Measurements and Disclosures. Marketable securities, at amortized cost We also invest in marketable securities. As noted in our Annual Report on Form 10-K for the year ended December 31, 2022, all our marketable securities are classified as held-to-maturity securities and reported at amortized cost pursuant to ASC 320, Investments – Debt and Equity Securities, as we have the intent and ability to hold all investments to maturity. Below is a summary of the amortized cost and estimated market values of our marketable securities as of September 30, 2023, and December 31, 2022. ​
