Bank Loan Loss Reserves (ALLL)
Banks lend money knowing some borrowers will default, but waiting for nonpayment before preparing is a direct path to insolvency. This course shows you how financial institutions calculate the Allowance for Loan and Lease Losses (ALLL) to absorb bad debt before it damages solvency. You will learn the mechanics of historical loss math, qualitative economic adjustments, and lifetime loss forecasting.

Key ideas in Bank Loan Loss Reserves (ALLL)
- A loan loss reserve is funded by taking an expense out of current earnings before defaults happen
- The reserve acts as a shock absorber so future uncollectible loans do not directly destroy bank capital and cause insolvency
- Setting aside the cushion in advance ensures the bank reports a realistic picture of its earnings and health
- Banks group loans with similar risk traits into distinct pools rather than applying a single flat rate across everything
- Historical default and recovery rates for each pool establish the baseline dollar amount needed in the reserve
- Higher-risk pools require larger reserve cushions than low-risk, collateral-backed pools
- Gross charge-offs represent the total face value of loans written off as uncollectible
- Recoveries are funds or seized asset values collected after a loan has been charged off
- Net charge-offs equal gross charge-offs minus recoveries, reflecting the bank's true economic loss
- The allowance is a contra-asset accounting entry on the balance sheet, not a separate cash account or vault stash
- It sits directly underneath gross loans on the balance sheet, subtracting from them to show the net loans the bank realistically expects to collect
- Money in the reserve remains working within the bank's general asset pool rather than sitting idle
- The coverage ratio compares the total loan loss reserve directly against total non-performing loans
- A ratio over 100% means the bank holds more than a dollar of reserves for every dollar of currently delinquent or troubled loans
- Analysts and regulators inspect the coverage ratio as an immediate check on whether the reserve cushion is thick enough for current problem loans
- Historical loss rates look backward and often understate risk when current economic conditions sour
