Allowance for Credit Losses
Also known as ACL
The allowance for credit losses (ACL) is the reserve a bank holds on its balance sheet against expected loan losses. It is a contra-asset that reduces gross loans to net loans, and under the CECL standard it reflects lifetime expected losses.
Formula
The allowance rolls forward each period: the prior balance, plus the provision expense, less net charge-offs (gross charge-offs minus recoveries). Schedule RI-C reconciles the movement; the ending balance appears as a contra-asset on Schedule RC.
Why it matters
The ACL is the buffer that absorbs credit losses before they hit capital. An allowance that is too thin relative to the risk in the loan book leaves the bank exposed; the adequacy of the ACL is a core focus of every safety-and-soundness exam and external audit.
How to interpret
The dollar allowance is best read as ratios: ACL to total loans (reserve depth) and ACL to nonperforming loans (the coverage ratio). A high ACL is not inherently good or bad — it can mean prudent reserving or a genuinely riskier book — so it must be read against the bank's actual loss experience and loan mix.
Thresholds
| Range | Label | Interpretation |
|---|---|---|
| Ample coverage of NPLs | Strong | Reserve comfortably exceeds nonperforming loans. |
| Adequate | Adequate | Allowance broadly consistent with the loss outlook. |
| Thin vs. risk | Watch | Reserve light relative to nonperforming loans or loan mix. |
| Under-reserved | Concern | Allowance well below likely losses; capital is the next line of defense. |
Worked example
Frequently asked
Is the allowance for credit losses the same as the old ALLL?
It is the CECL-era successor to the allowance for loan and lease losses (ALLL). CECL broadened the reserve to cover lifetime expected losses and extended it to held-to-maturity securities and some off-balance-sheet exposures.
Does a bigger allowance mean a bank is safer?
Not necessarily. A large allowance can reflect prudent reserving or a genuinely high-risk loan book. Read it as the ACL-to-loans and coverage ratios alongside actual charge-off history.
