Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 16. Fair Value Measurements Certain assets and liabilities are recorded at fair value on the consolidated balance sheets and are measured and classified based upon a three-tiered approach to valuation. Financial assets and liabilities recorded at fair value and are classified and disclosed in one of the following three categories: Level 1 – Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2 – Quoted prices for identical or similar financial instruments in markets that are not considered to be active, or similar financial instruments for which all significant inputs are observable, either directly or indirectly, or inputs other than quoted prices that are observable, or inputs that are derived principally from or corroborated by observable market data through correlation or other means; and Level 3 – Prices or valuations that require inputs that are both significant to the fair value measurement and are unobservable. These reflect management’s assumptions about the assumptions a market participant would use in pricing the asset or liability. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Fair values of cash equivalents approximate carrying value due to the short period of time to maturity. Fair values of short-term investments are based on quoted market prices. Fair values of investments available-for-sale are based on quoted market prices, dealer quotes or discounted cash flows. Fair values on interest rate swap contracts are based on using pricing valuation models which include broker quotes. Fair values of long-term investments and mortgage loans and notes on real estate are based on quoted market prices, dealer quotes or discounted cash flows. Fair values of trade receivables approximate their recorded value. Our financial instruments that are exposed to concentrations of credit risk consist primarily of temporary cash investments, trade receivables, reinsurance recoverables and notes receivable. Limited credit risk exists on trade receivables due to the diversity of our customer base and their dispersion across broad geographic markets. We place our temporary cash investments with financial institutions and limit the amount of credit exposure to any one financial institution. We have mortgage receivables, which potentially expose us to credit risk. The portfolio of notes is principally collateralized by self-storage facilities and commercial properties. We have not experienced any material losses related to the notes from individual or groups of notes in any particular industry or geographic area. The estimated fair values were determined using the discounted cash flow method and using interest rates currently offered for similar loans to borrowers with similar credit ratings. Other investments including short-term investments are substantially current or bear reasonable interest rates. As a result, the carrying values of these financial instruments approximate fair value. The carrying values and estimated fair values for the financial instruments stated above and their placement in the fair value hierarchy are as follows: Fair Value Hierarchy As of March 31, 2023 Carrying Value Level 1 Level 2 Level 3 Total Estimated Fair Value (In thousands) Assets Reinsurance recoverables and trade receivables, net $ 189,498 $ – $ – $ 189,498 $ 189,498 Mortgage loans, net 466,531 – – 444,957 444,957 Other investments 109,009 – – 109,009 109,009 Total $ 765,038 $ – $ – $ 743,464 $ 743,464 Liabilities Notes, loans and finance leases payable $ 6,143,350 $ – $ 5,710,735 $ – $ 5,710,735 Total $ 6,143,350 $ – $ 5,710,735 $ – $ 5,710,735 .
