What it means
Banks and finance companies earn money by lending it out and collecting interest. When a borrower falls badly behind, the loan is no longer producing the income it was written for, so it is reclassified as nonperforming.
The most common trigger is ninety days past due, though a loan can also be classified early if the lender judges full repayment unlikely. The reclassification has real accounting consequences.
The lender stops accruing interest income, often reverses interest it previously booked but never collected, and raises a provision, which is an expense set aside for the amount it expects to lose. Profit falls twice over: the income stops and a charge is taken.
Two numbers do most of the work when analysing a loan book. The nonperforming loan ratio shows what share of total lending has gone bad, and the coverage ratio shows how much of that bad lending is already provided for.
A rising ratio with falling coverage is the combination that worries regulators and investors most. Nonperforming does not mean written off.
Many such loans are eventually cured through restructuring, partial repayment or the sale of security, and lenders track recovery rates closely. Others are sold in bulk to specialist buyers at a discount, which cleans the balance sheet in exchange for accepting a certain loss now.
The concept matters beyond banking, because any business that extends credit faces the same question. A distributor with a large receivables book effectively runs a small lending operation and should ask which customer balances have stopped performing rather than waiting for a formal default.
In practice
Real-world examples.
Example
A community bank finds that a builder is ninety-five days past due on a $2,400,000 development loan. The loan is moved to nonperforming, and $180,000 of interest accrued but never received is reversed out of income.
Example
An equipment finance company reviews 1,000 contracts and identifies 40 with balances totalling $6,000,000 against a book of $150,000,000. That is a nonperforming ratio of 4%, above the 2.5% the board has set as its internal limit.
Example
A credit union with $9,000,000 of nonperforming loans is told by its auditor that provisions of $4,500,000, or 50% coverage, are too thin given weak security. It raises the allowance to $6,300,000, taking coverage to 70% and reducing reported profit for the year.
Formula
Calculation
Nonperforming Loan Ratio = Nonperforming Loans / Total Gross Loans. Coverage Ratio = Loan Loss Allowance / Nonperforming Loans.
A regional lender has total gross loans of $600,000,000, of which $18,000,000 are ninety days or more past due. Its loan loss allowance stands at $12,600,000.
Nonperforming loan ratio = $18,000,000 / $600,000,000 = 0.03, or 3%.
Coverage ratio = $12,600,000 / $18,000,000 = 0.70, or 70%.
So three cents in every dollar lent is not performing, and the lender has already recognised losses on seventy cents of every problem dollar, leaving $5,400,000 of unprovided exposure.Case study
Seen in the real world.
Brightwater Community Bank is an illustrative and entirely fictional lender created to show how these ratios move. It carries a loan book of $850,000,000, and for several years its nonperforming loans sat at roughly $12,750,000, a comfortable 1.5% of lending. Most of the book was residential mortgages with conservative deposits behind them.
A downturn in the local manufacturing sector changed that within eighteen months. Nonperforming loans climbed to $29,750,000, or 3.5% of the book, concentrated in commercial lending to suppliers of a single large plant. The bank had not tracked how much of its book depended on one employer.
The response combined three actions: raising provisions to restore coverage, restructuring viable borrowers onto interest-only terms for a year, and capping new lending to that sector at 10% of the book. Two years later the ratio had fallen back below 2%, and the concentration limit became a permanent part of the credit policy.
Watch out
Common mistakes.
- Reading a nonperforming loan as money already lost, when a good share of such loans are cured or partly recovered through security.
- Looking at the nonperforming ratio without the coverage ratio, which hides whether the lender has actually recognised the likely losses.
- Comparing ratios across countries or lenders without checking the classification rules, since definitions of past due and impairment vary.
Questions
People also ask.
What is the difference between nonperforming and default?
Default is a breach of the loan agreement, which can happen for reasons other than missed payments, while nonperforming is specifically about payments having stopped.
Does interest keep accruing on a nonperforming loan?
Not in the accounts, because the lender stops recognising interest as income even though the contract may still legally require the borrower to pay it.
Can a nonperforming loan become performing again?
Yes, if the borrower brings payments up to date and sustains them for an agreed period, the loan is reclassified and provisions can be released.
