The Company measures the fair value of money market funds and foreign deposits, classified as Level 1, based on quoted prices in active markets for identical assets. The Company's fixed maturity investments classified as either Level 1 or Level 2 in the above tables are priced exclusively by external sources, including pricing vendors, dealers/market makers, and exchange-quoted prices. The fair value of the Company's fixed maturity investments classified as Level 2 is based on either recent trades in inactive markets or quoted market prices of similar instruments and other significant inputs derived from or corroborated by observable market data. Held-to-maturity investments are carried at amortized cost and the fair value and changes in unrealized gains (losses) are disclosed in Note 3, Investments. The fair value of these investments is determined in the same manner as available-for-sale securities and are considered either a Level 1 or Level 2 measurement.

The Company's preferred stock investment (see Note 4) is accounted for as an available-for-sale debt security, and measured at fair value at each balance sheet date. The estimated fair value of the preferred stock investment is a Level 3 measurement, and is based on certain unobservable inputs such as the value of the underlying enterprise, volatility, time to liquidity, and market interest rates. An increase or decrease in any of these unobservable inputs would result in a change in the fair value measurement. The estimated fair value was $5.3 million as of March 31, 2024, unchanged from December 31, 2023, and is recorded in other long-term assets on the Company's consolidated balance sheet.

The Company recognizes transfers between levels of the fair value hierarchy on the date of the event or change in circumstances that caused the transfer. There were no transfers between levels for the three months ended March 31, 2024 and the year ended December 31, 2023.

The following table presents the change in fair value of the Company’s investment carried at fair value and classified as Level 3 as of March 31, 2024 and 2023 (in thousands):


	Preferred Stock Investment

Fair Value Disclosures - Other Assets and Liabilities

The Company's other long-term assets balance also included notes receivable of $6.1 million and $6.8 million as of March 31, 2024 and December 31, 2023, respectively, recorded at their estimated collectible amount. The Company estimates that the carrying value of the notes receivable approximates the fair value. The estimated fair value represents a Level 3 measurement within the fair value hierarchy, and is based on market interest rates and the assessed creditworthiness of the third party.

The Company estimates the fair value of long-term debt based upon rates currently available to the Company for debt with similar terms and remaining maturities. This is a Level 3 measurement. Based upon the terms of the debt, the carrying amount of long-term debt approximated fair value at March 31, 2024.
