Fair Value Disclosures [Abstract]  
Fair Value Measurements Fair Value Measurements
We consider the carrying amounts of current assets and current liabilities to approximate their fair values because of the relatively short period of time between the origination of these instruments and their expected realization or payment. For our financial instruments measured at fair value on a recurring basis, we prioritize the inputs used in measuring fair value according to the three-tier fair value hierarchy. For a description of the methods and assumptions used to: a) estimate the fair value; and b) determine the classification according to the fair value hierarchy for each financial instrument, refer to our 2023 Annual Report on Form 10-K, Note 5, “Fair Value Measurements.”
Our financial instruments measured at fair value on a recurring basis at March 31, 2024, were as follows:

Fair Value Measurements – Disclosure Only
The carrying amounts and estimated fair values of our notes payable are classified as Level 2 financial instruments. Fair value for these securities is determined using a market approach based on quoted market prices for similar securities in active markets or quoted prices for identical securities in inactive markets.
