Loan loss provision
Recognize losses BEFORE they happen, not after.

You have a ₦1,000,000 loan book. Industry experience says ~3% of loans default. Bad-debt write-off (Lesson 16) is reactive, when a specific loan turns bad, you write it off. Provisioning is PROACTIVE, you set aside a reserve today for losses you EXPECT to happen, before any specific loan defaults. This is the difference between honest financial reporting and discovering ugly surprises at year-end audit. IFRS 9 and US CECL both mandate forward-looking provisioning for any serious lender.
If you lend to a thousand people, some of them will not pay you back. You do not know which ones yet, but you know the rate from history, and pretending the loss is zero until a specific borrower defaults is wishful accounting. Provisioning is recognizing that expected loss today, while every loan still looks healthy, instead of waiting for the bad news to name itself.
The mechanism is a contra-asset. You debit Loan Loss Provision Expense, so the expected loss hits this period's P&L, and you credit Allowance for Loan Losses, an asset account whose normal balance runs opposite to the loans it offsets. Loan Receivable still reads ₦1,000,000 on its own line, but the net carrying value on the balance sheet is ₦1,000,000 minus the ₦30,000 allowance, ₦970,000. You are not erasing any loan; you are reporting what you honestly expect to collect.
That is the payoff when a real default lands. You debit the allowance and credit Loan Receivable, removing the bad loan and eating into the cushion, with no expense entry at all, because the pain was already taken at provision time. If your provisioning was accurate, actual write-offs barely register on the income statement; they are non-events. Hitting the expense again at default would be charging yourself for the same loss twice.
Worked example, step by step
Set the stage: disburse ₦1,000,000 of loans
Imagine ten ₦100,000 loans, or one ₦1,000,000 loan. Either way, your loan book is now ₦1,000,000.
| Account | Debit | Credit |
|---|---|---|
| Loan Receivable (1800) | ₦1,000,000.00 | |
| Bank Account (1200) | ₦1,000,000.00 |
Loan Receivable UP ₦1,000,000. Bank Account DOWN ₦1,000,000. Standard disbursement, same as Lesson 28 just at scale.
Provision 3% (₦30,000) for expected losses
Don't wait for actual defaults. Based on portfolio history, you expect 3% of loans to default. Book the ₦30,000 expected loss NOW, as both an expense AND a contra-asset that reduces the net loan book on your balance sheet.
| Account | Debit | Credit |
|---|---|---|
| Loan Loss Provision Expense (5700) | ₦30,000.00 | |
| Allowance for Loan Losses (1850) | ₦30,000.00 |
Loan Loss Provision Expense UP ₦30,000, the loss hits P&L today. Allowance for Loan Losses (a contra-asset, normal balance opposite to its parent asset) UP ₦30,000. After this: Loan Receivable still shows ₦1,000,000, but on the balance sheet the NET receivable is ₦1,000,000 - ₦30,000 = ₦970,000. The investors see the real expected economics.
A loan actually defaults ₦20,000, use the allowance, not P&L
Months later, one borrower defaults. ₦20,000 must be written off. But you DON'T hit P&L again, the loss was already recognized at provision time. You USE the allowance you already built.
| Account | Debit | Credit |
|---|---|---|
| Allowance for Loan Losses (1850) | ₦2,000.00 | |
| Loan Receivable (1800) | ₦2,000.00 |
Allowance for Loan Losses DOWN ₦20,000, eat into the cushion. Loan Receivable DOWN ₦20,000, remove the bad loan from the book. Notice: NO expense entry. The pain was felt at provision time. This is the entire POINT of provisioning, losses are recognized when expected, not when realized. If provisioning is accurate, write-offs are non-events on your P&L.
Takeaway
Provisioning is the discipline of recognizing expected losses before they materialize. Build the allowance from historical default rates. When a loan actually goes bad, use the allowance, don't hit P&L twice. If your provision is accurate, actual write-offs barely register on your income statement. Regulators care deeply: under-provisioning lets you flatter your earnings short-term but blows up audits and loses you your license. Over-provisioning hides profit and pisses off your CFO. The sweet spot is honest historical analysis applied consistently every period.
