	June 30, 2023				September 30, 2022

(a) Carrying amounts are net of unamortized debt issuance costs or accretion.

(b) The estimated fair value for our publicly-held Senior Notes have been determined using quoted market rates (Level 2).

(c) Since there is no trading market for our Junior Subordinated Notes, the fair value of these notes is estimated by discounting scheduled cash flows through maturity (Level 3). The discount rate is estimated using market rates currently being offered on loans with similar terms and credit quality. Judgment is required in interpreting market data to develop these estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts that we could realize in a current market exchange.
