Financial statements are prepared at a specific date, but the business world doesn't pause for accounting periods. Libby's Chapter 4 introduces the four types of adjusting entries that bridge the gap between when cash moves and when revenues and expenses actually belong — the mechanical heartbeat of accrual accounting.
Under cash accounting, every transaction is fully recorded when cash moves — simple and clean. Under accrual accounting, which GAAP requires, the timing of cash and the timing of economic activity often differ. A company prepays insurance for 12 months. It receives cash for a subscription covering the next year. An employee works in December but won't be paid until January. In all three cases, the original cash transaction was recorded correctly — but by year-end, the financial statements don't yet reflect economic reality. Adjusting entries fix this.
Adjusting entries are made at the end of every accounting period (monthly, quarterly, annually) before financial statements are prepared. They never involve cash — if cash is part of the entry, it's not an adjusting entry. They always involve at least one balance sheet account and one income statement account. Their purpose is to ensure revenues are recognized when earned and expenses are recognized when incurred, regardless of when cash changed hands.
Every adjusting entry falls into one of four categories: (1) Deferred Revenue — cash received before service delivered; (2) Deferred Expense (Prepaid) — cash paid before benefit received; (3) Accrued Revenue — service delivered before cash received; (4) Accrued Expense — expense incurred before cash paid. The first two are deferrals (cash came first); the last two are accruals (recognition comes first).
Four Types of Adjusting Entries
All adjusting entries: one income statement account + one balance sheet account. No cash.
DEFERRALS — Cash Moved First
Cash received/paid before recognition
ACCRUALS — Activity Happened First
Revenue earned / expense incurred before cash
Deferred Revenue
Liability → Revenue
Original Entry
DR Cash / CR Unearned Revenue
Adjusting Entry
DR Unearned Revenue / CR Revenue
Gift cards, subscriptions, advance payments
Liability decreases as service is delivered
Deferred Expense (Prepaid)
Asset → Expense
Original Entry
DR Prepaid Asset / CR Cash
Adjusting Entry
DR Expense / CR Prepaid Asset
Prepaid insurance, prepaid rent, software licenses
Asset consumed into expense over time
Accrued Revenue
Revenue Earned, Cash Later
Original Entry
(No original entry — nothing recorded yet)
Adjusting Entry
DR Receivable / CR Revenue
Interest earned, services performed but not billed
Creates asset and recognizes earned income
Accrued Expense
Expense Incurred, Cash Later
Original Entry
(No original entry — nothing recorded yet)
Adjusting Entry
DR Expense / CR Payable
Wages payable, interest payable, warranty obligations
Creates liability and recognizes owed expense
Figure 4.1 — All four adjusting entry types. Adjusting entries never involve cash — they exist solely to align recognition with economic reality.
Deferrals occur when cash has already moved but the corresponding revenue or expense hasn't been fully earned or used yet. The cash transaction was recorded correctly at the time; the adjusting entry simply updates the balance sheet to reflect how much has now been earned or consumed.
Papa John's sells $500,000 in gift cards in December. Cash arrives in December; no food has been sold yet. Original entry: DR Cash $500,000 / CR Deferred Revenue $500,000 (liability). By December 31st, $80,000 of gift cards have been redeemed. Adjusting entry: DR Deferred Revenue $80,000 / CR Revenue $80,000. The remaining $420,000 stays as a liability — a real obligation to provide food. Revenue is recognized as customers redeem cards, not when cards are sold.
On October 1st, a company pays $24,000 for 12 months of insurance coverage. Original entry: DR Prepaid Insurance $24,000 / CR Cash $24,000. At December 31st (3 months elapsed), 3/12 has been consumed. Adjusting entry: DR Insurance Expense $6,000 / CR Prepaid Insurance $6,000. The remaining $18,000 stays as a prepaid asset — representing future coverage already paid for. Without the adjustment, December's income statement would show no insurance expense and the balance sheet would show $24,000 of unexpired coverage.
| Type | Original Entry | What the Adjustment Does | Adjusting Entry |
|---|---|---|---|
| Deferred Revenue | DR Cash / CR Unearned Revenue (liability) | Converts liability to revenue as service is performed | DR Unearned Revenue / CR Revenue |
| Deferred Expense (Prepaid) | DR Prepaid Asset / CR Cash | Converts asset to expense as benefit is consumed | DR Expense / CR Prepaid Asset |
Accruals occur when economic activity has taken place but no cash has moved yet and no transaction has been recorded. At year-end, the accountant must record what has been earned or owed to ensure the period's financial statements capture all economic activity.
A company holds a $100,000 note receivable at 6% annual interest. By December 31st, two months of interest have been earned ($100,000 × 6% × 2/12 = $1,000) but the interest won't be paid until the note matures in February. No cash, no original entry — but the revenue was earned. Adjusting entry: DR Interest Receivable $1,000 / CR Interest Revenue $1,000. This creates both an asset (money owed to the company) and the income it represents.
Employees work December 25–31 and will be paid on January 5th. The company owes $45,000 in wages for this period. No cash has moved; no entry has been made. But the expense was incurred in December — it belongs on December's income statement. Adjusting entry: DR Wages Expense $45,000 / CR Wages Payable $45,000. This creates both the liability (money owed to employees) and the expense. When paid in January: DR Wages Payable $45,000 / CR Cash $45,000.
| Type | Situation | Adjusting Entry | Follow-up Cash Entry |
|---|---|---|---|
| Accrued Revenue | Service delivered, cash not yet received | DR Receivable / CR Revenue | DR Cash / CR Receivable (when cash arrives) |
| Accrued Expense | Expense incurred, cash not yet paid | DR Expense / CR Payable | DR Payable / CR Cash (when paid) |
To illustrate the cumulative impact, suppose a company is preparing its December 31st financial statements. The following adjustments are required:
| Item | Facts | Adjusting Entry | Income Statement Effect |
|---|---|---|---|
| Prepaid Insurance | $12,000 paid July 1 for 12 months; 6 months elapsed | DR Insurance Expense $6,000 / CR Prepaid Insurance $6,000 | Expense increases $6,000 → profit decreases $6,000 |
| Deferred Subscription Revenue | $36,000 received Oct 1 for 12-month subscription; 3 months elapsed | DR Unearned Revenue $9,000 / CR Subscription Revenue $9,000 | Revenue increases $9,000 → profit increases $9,000 |
| Accrued Wages | $22,000 wages earned Dec 25–31, to be paid Jan 10 | DR Wages Expense $22,000 / CR Wages Payable $22,000 | Expense increases $22,000 → profit decreases $22,000 |
| Depreciation | Annual depreciation on equipment = $18,000 | DR Depreciation Expense $18,000 / CR Accum. Depr. $18,000 | Expense increases $18,000 → profit decreases $18,000 |
| Accrued Interest Receivable | $5,000 interest earned but not yet received | DR Interest Receivable $5,000 / CR Interest Revenue $5,000 | Revenue increases $5,000 → profit increases $5,000 |
Net effect on pre-tax income: −$6,000 − $22,000 − $18,000 + $9,000 + $5,000 = −$32,000. Without these adjustments, the company would have overstated income by $32,000. Every adjustment has a real economic basis — these are not arbitrary — but each involves an estimate (how many months of subscription have been earned? what is the useful life of equipment?). Those estimates are where earnings management risk lives.
Because adjusting entries require estimates, they are also where intentional earnings manipulation most commonly occurs. A company can underestimate warranty expense accruals, understate the bad debt provision, delay recognizing warranty obligations, or extend the useful life of PP&E to reduce depreciation. None of these are immediately obvious from reading the financial statements — they require comparison to industry peers, trend analysis over multiple periods, and reading the footnotes for changes in accounting estimates. Auditors test the reasonableness of these estimates, but significant judgment remains with management.
