# Impact of Adjusting Entries on the Trial Balance

There are five types of adjusting entries that may affect the trial balance. Throughout this adjusting process, there is a flow of information from journal entries to adjusting entries, to the general ledger, through to the adjusted trial balance.

A trial balance summarizes information in the general ledger and lists the accounts and their balances at a certain point in time. An unadjusted trial balance is a list of accounts and balances prior to adjustments being made for any adjusting entries at the end of the accounting period. Once the impact, or effect, of the adjusting entries is reflected in the accounts, the result is an adjusted trial balance. This adjusted trial balance is a list of general ledger accounts with proper balances after entries are posted in the ledger. The balances in the adjusted trial balance are used to prepare the financial statements.

The following are examples of the five types of adjusting entries: accrued revenue, accrued expense, unearned or deferred revenue, prepaid expense, and depreciation expense. This company is on a monthly period, though accumulated depreciation would not necessarily be recorded monthly but at the end of whatever period is set. The adjusting entries are then reflected and cross-referenced in the adjusting entries column in Adjusted Trial Balance July 31 Global Air.
