Charge-Off Ratio: How Banks Recognize Loan Losses

Key Takeaways

• Charge-off ratio equals net charge-offs divided by average loans, typically annualized.
• US bank regulators require charge-off of unsecured consumer loans once 120 days past due, and 180 days for closed-end installment.
• The aggregate US net charge-off rate ran near 0.4% in normal cycles and peaked above 3% during 2009-2010.
• Charge-offs cut the allowance for credit losses, not earnings directly, but they signal whether prior provisioning was adequate.

What It Is

A charge-off is the accounting act of removing a loan, or a portion of a loan, from the bank's books because the bank no longer expects to collect it. Banks debit the allowance for credit losses and credit loans receivable. Earnings are not hit directly at the moment of charge-off, but the move tests whether the prior provision was sufficient.

The OCC, FDIC, and Federal Reserve supervise charge-off practices through the Uniform Retail Credit Classification policy and the Comptroller's Handbook on allowances for credit losses. Banks file charge-off data on Schedule RI-B of the FFIEC call report.

The Intuition

Provisions are forward-looking estimates of expected loss. Charge-offs are realized losses. The gap between the two tells you whether the bank was too optimistic, too pessimistic, or accurate in earlier periods.

When charge-offs run above provisions for several quarters, the allowance shrinks and the bank eventually must provision more to rebuild it, which hits earnings. When charge-offs run below provisions, the allowance grows, which may indicate conservative reserving or improving credit.

How It Works

The headline formula uses net charge-offs.

Net Charge-Off Ratio = (Gross Charge-Offs - Recoveries) / Average Loans

Gross charge-offs are loans written off in the period. Recoveries are subsequent collections on previously charged-off loans. Net charge-offs (NCO) are the difference. Average loans is typically the average of beginning and ending gross loans.

The ratio is usually expressed on an annualized basis. A quarterly NCO of 0.10% of average loans equates to a 0.40% annualized rate.

Regulatory rules force timing on retail charge-offs.

Loan type                        Charge off when
Closed-end installment           180 days past due
Open-end consumer credit         180 days past due
Credit cards                     180 days past due
Other unsecured retail           120 days past due
Bankruptcy filings               within 60 days of notification
Deceased borrowers               within 60 days

Commercial loans are charged off based on the bank's judgment that the loan is uncollectible, subject to examiner review. Real estate loans typically are charged down to fair value of collateral less selling costs.

Worked Example

A credit-card-focused bank reports the following.

Average loans (Q):                        $30,000 million
Gross charge-offs (Q):                    $    180 million
Recoveries (Q):                           $     30 million
Net charge-offs (Q):                      $    150 million

NCO ratio (quarter)   = 150 / 30,000      = 0.50%
NCO ratio (annualized) = 0.50% x 4         = 2.00%

A 2% annualized credit-card NCO is in line with normal cycle levels for prime portfolios. Subprime card portfolios can run 5% to 8% in normal times and 10% to 15% in stress.

If the bank provisioned $200 million for credit losses this quarter, the allowance increased by 200 - 150 = $50 million. If it had only provisioned $120 million, the allowance would have shrunk by $30 million, which over time forces a catch-up provision.

Common Mistakes

1. Quoting gross instead of net. Recoveries are real cash that should offset gross charge-offs. Using gross overstates the loss rate by 10% to 30% in normal cycles.
2. Forgetting to annualize. Quarterly charge-off ratios look small compared to peer disclosures that are annualized. Always confirm the basis.
3. Comparing across segments without context. Credit card NCOs naturally run 5x to 10x the level of residential mortgage NCOs. Mixing them inflates or hides risk.
4. Reading NCO without the provision number. A low NCO with rising provisions can flag that management sees trouble in the pipeline. A high NCO with flat provisions can flag reserve depletion.
5. Ignoring the timing rules. A bank that lags on charge-off recognition reports a flattering NCO ratio temporarily, but the catch-up is forced by examiners.

Frequently Asked Questions

What is the charge off ratio banking metric in simple terms? It is the share of a bank's loan portfolio that the bank has formally written off as uncollectible during a period, after subtracting recoveries on past write-offs. The figure is usually annualized for comparability.

How does the charge-off ratio affect investment decisions? For bank equity investors, a rising NCO ratio raises the probability of higher future provisioning, which directly cuts earnings. For credit investors, sustained high NCOs erode capital and can change the bank's risk profile.

What is a real-world example of a charge-off cycle? US aggregate net charge-offs rose from about 0.6% in 2007 to above 3% in 2010, driven by residential mortgages, construction loans, and credit cards. Several large banks needed capital raises as a result.

How can investors use charge-off disclosures effectively? Look at NCO by loan segment, the trend over four to eight quarters, and the relationship between NCO and provisions. Divergence between the two is the early signal of reserve adequacy issues.

How is the charge-off ratio different from the NPL ratio? The NPL ratio is a stock measure of currently impaired loans on the balance sheet. The charge-off ratio is a flow measure of loans the bank has formally written off during the period.
