 Methodologies Used in the Stress Test DFAST Stress Test Results | p. 7 Category Methodology Loan Charge-offs • Charge-offs for the larger loan segments were derived using regression models developed using historical charge-off data for the Company and peer banks selected for each loan segment; model-derived results were adjusted in some cases based on management judgment • Charge-offs for smaller loan segments were projected based on peer bank loss history Allowance for Loan and Lease Losses (“ALLL”); Loan Loss Provision (“LLP”) • The ALLL at the end of each quarter was estimated using a model that combines outputs from the charge-off models, historical probability of default (PD) and loss given default (LGD) rates by loan segment, and adjustments to the PD and LGD rates during the course of the scenario; LLP is derived from changes in the ALLL balances Loan, Security and Deposit Balances • Loan balances for the larger loan segments were derived using regression models developed using historical loan balances for the Company and peer banks selected for each loan segment; model-derived results were adjusted in some cases based on management judgment • Loan balances for smaller loan segments were projected based on management judgment • Deposit balances were based on a regression model developed using historical data for the Company and a group of peer banks • Security balances were based on funding and liquidity needs driven by the loan balance and deposit models Pre Provision Net Revenue (“PPNR”); Losses on Securities • PPNR equals net interest income plus non interest income less non interest expense; PPNR excludes LLP and losses on securities • PPNR is estimated by combining assumptions from the loan and deposit balance models above; forward curves from the regulatory scenario; security yields based on regression models; and assumptions for loan spreads, non interest income and non interest expense levels based on Company history and management judgment • Losses on securities were estimated using a combination of regression models, historical market data and management judgment Regulatory Capital, Risk Weighted Assets (“RWA”), Adjusted Assets (“AA”) • Regulatory capital, RWA and AA were derived using outputs from the models above and applying the Basel III rules •The key methodologies used to prepare the stress test are summarized below •The stress test assumptions and results were reviewed and approved by management and the Board
