Allowance for Loan Losses
The Allowance for Loan Losses (ALL) is a contra-asset reserve on a bank's balance sheet representing the cumulative amount set aside to absorb expected future credit losses on the outstanding loan portfolio, funded through the provision for credit losses expense.
The allowance for loan losses (also called the allowance for credit losses under the CECL framework) sits on the balance sheet as a deduction from gross loans receivable, producing the net loan figure. If a bank has $10 billion in gross loans and a $200 million allowance, net loans on the balance sheet equal $9.8 billion — representing management's estimate of the collectible value of the loan portfolio.
The reserve coverage ratio — allowance as a percentage of total loans — is a widely tracked metric. Investment-grade commercial banks in the US have historically maintained coverage ratios of 1-2%, rising to 3-5% during severe credit cycles. Reserve adequacy is evaluated relative to non-performing loans (NPL coverage ratio: allowance divided by non-accrual and past-due loans), with ratios above 100% generally considered adequate.
Under the CECL standard, the allowance must reflect estimated losses over the entire life of the loan, incorporating reasonable and supportable economic forecasts. This expands the scope of the reserve substantially compared to the pre-CECL incurred loss model, which required only the reserve for losses incurred (probable and estimable). CECL implementation increased aggregate bank allowances significantly and introduced more cyclicality into the reserve as economic forecasts change.
Regulatory capital implications are important: the allowance for loan losses is not included in Tier 1 capital under Basel III, though a limited amount (up to 1.25% of risk-weighted assets) may be included in Tier 2 capital. Banks must hold sufficient regulatory capital to absorb unexpected losses beyond what the allowance covers — the distinction between expected losses (reserve) and unexpected losses (capital) is a foundational concept in bank risk management.
When a loan is actually charged off, the loss is debited against the allowance — it does not directly hit the income statement at that time. This is why provision expense (which builds the allowance) is the income statement impact of credit deterioration, while actual charge-offs are a balance sheet event. Analysts monitor whether provision expense is keeping pace with charge-offs to assess whether the allowance is being depleted.
