Loans in hardship and other forbearances (excluding loans in an extended grace period and delinquent loans in disaster forbearance) were approximately $166 million and $159 million at September 30, 2025 and 2024, respectively.

(3) We calculate and report our Return on Assets (“ROA”) as the ratio of (a) GAAP net income (loss) numerator (annualized) to (b) the GAAP total average assets denominator.

(4) We calculate and report our Return on Common Equity (“ROCE”) as the ratio of (a) GAAP net income (loss) attributable to common stock numerator (annualized) to (b) the net denominator, which consists of GAAP total average equity less total average preferred stock.
