Fair Value Disclosures [Abstract] |
FAIR VALUE MEASUREMENTS | FAIR VALUE MEASUREMENTS In determining fair value, there is a three-level hierarchy based on the reliability of the inputs used. Level 1 refers to fair values based on quoted prices for identical instruments in active markets. Level 2 refers to fair values estimated using significant other observable inputs such as similar instruments in active markets or quoted prices for identical or similar instrument in markets that are not active. Fair values for Level 2 instruments are determined using standard valuation models that incorporate inputs such as quoted prices for similar assets, interest rates, benchmark curves, credit ratings, and other observable inputs or market data. Level 3 refers to fair values estimated using significant unobservable inputs for which there is little or no market data and that are significant to the fair value of the assets. Fair values for Level 3 instruments are determined using future cash flows and discount rates, which include information obtained from third-party valuation sources and other market sources, including recent offers from potential buyers. Fair value of financial instruments on a recurring basis As of December 31, 2024, cost basis and fair value for marketable securities was $1.3 billion. Differences in cost basis and fair value of marketable securities are primarily a result of changes in interest rates and general market conditions. The Company does not believe any unrealized losses are the result of credit quality based on its evaluation and duration exposure, credit ratings of the securities, liquidity profiles, and other observable information as of December 31, 2024.
