The provision for credit losses is the expense recognized to reflect changes in expected credit losses. Provision is a period expense, not a balance-sheet reserve. For banks using CECL, provision expense is one of the main ways the Allowance for Credit Losses is adjusted through earnings.
A simplified relationship is:
Provision ≈ Ending ACL - Beginning ACL + Net charge-offs - Other allowance adjustments
This is a reconciliation identity, not a universal forecasting formula. Acquisition accounting, securities allowances, unfunded commitments, and other adjustments can complicate the roll-forward.
Provision versus allowance
These terms are related but not interchangeable:
- Allowance for credit losses: balance-sheet valuation account measured at a point in time.
- Provision for credit losses: income-statement expense recorded over a period.
- Net charge-offs: realized charge-offs less recoveries over a period.
A bank can record provision expense before borrowers actually default because CECL is based on expected losses, not only losses already incurred.
Why provision expense moves
Provision expense can change because of:
- changes in expected economic conditions;
- loan growth or contraction;
- changes in portfolio mix or borrower risk;
- updated loss models and qualitative adjustments;
- deterioration or improvement in specific credits;
- acquisitions; and
- realized charge-offs relative to the existing allowance.
A high provision is therefore not automatically evidence that current charge-offs are high. It can reflect a forward-looking reserve build.
Example
A bank starts the quarter with a $200 million ACL. It records $25 million of provision expense, has $14 million of charge-offs, and receives $4 million of recoveries.
Net charge-offs are $10 million, so the simplified ending allowance is:
$200m + $25m - $10m = $215m
The $25 million provision reduces pretax income for the quarter. The ending $215 million ACL remains on the balance sheet as an estimate of expected losses.
Investor interpretation
Provision expense is most useful when read alongside:
- loan growth;
- allowance coverage;
- nonperforming and criticized loans;
- Net Charge-Off Rate;
- management's macroeconomic assumptions; and
- prior reserve builds or releases.
A reserve release can boost earnings, but that does not necessarily mean the underlying business suddenly became more profitable. Likewise, a reserve build can reduce current earnings while strengthening loss absorption for expected future credit deterioration.
