or revenues to be recorded in the period in which they are earned, and for expenses to be recognized in the period in which they are incurred, companies make adjusting entries. Adjusting entries ensure that the revenue recognition and expense recognition principles are followed.

Adjusting entries are necessary because the trial balance may not contain up-to-date and complete data.

This is true for several reasons:

1. Some events are not recorded daily because it is not efficient to do so. Examples are the use of supplies and the earning of wages by employees.

2. Some costs are not recorded during the accounting period because these costs expire with the passage of time rather than as a result of recurring daily transactions. Examples are charges related to the use of buildings and equipment, rent, and insurance.

3. Some items may be unrecorded. An example is a utility service bill that will not be received until the next accounting period.

Adjusting entries are required every time a company prepares financial statements. The company analyzes each account in the trial balance to determine whether it is complete and up to date for financial statement purposes. Every adjusting entry will include one income statement account and one balance sheet account.

Types of Adjusting Entries

Adjusting entries are classified into two; either deferrals or accruals.

To defer means to postpone or delay. Deferrals are costs or revenues that are recognized at a date later than the point when cash was originally exchanged. Companies make adjusting entries for deferrals to record the portion of the deferred item that was incurred as an expense or earned as revenue during the current accounting period. The two types of deferrals are prepaid expenses and unearned revenues.


Companies record payments of expenses that will benefit more than one accounting period as assets called prepaid expenses or prepayments. When expenses are prepaid, an asset account is increased (debited) to show the service or benefit that the company will receive in the future. Examples of common prepayments are insurance, supplies, advertising, and rent. In addition, companies make prepayments when they purchase buildings and equipment.

Prepaid expenses are costs that expire either with the passage of time (e.g., rent and insurance) or through use (e.g., supplies). The expiration of these costs does not require daily entries, which would be impractical and unnecessary. Accordingly, companies postpone the recognition of such cost expirations until they prepare financial statements. At each statement date, they make adjusting entries to record the expenses applicable to the current accounting period and to show the remaining amounts in the asset accounts.


Companies record cash received before revenue is earned by increasing (crediting) a liability account called unearned revenues. Items like rent, magazine subscriptions, and customer deposits for future service may result in unearned revenues.

Airlines such as United, American, and Delta, for instance, treat receipts from the sale of tickets as unearned revenue until the flight service is provided. Unearned revenues are the opposite of prepaid expenses. Indeed, unearned revenue on the books of one company is likely to be a prepaid expense on the books of the company that has made the advance payment.

When a company receives payment for services to be provided in a future accounting period, it increases (credits) an unearned revenue (a liability) account to recognize the liability that exists.
