A few account balances remain the same because no adjustments have affected them. For illustration the balance in Accounts Payable doesn't change and is simply extended to the Adjusted Trial Balance columns. At present total the Adjusted Trial Balance debit and credit columns. The totals should be equal before taking the next step in completing the work sheet. When the Adjustments columns and Trial Balance both balance but the Adjusted Trial Balance columns don't the most probable cause is a math error or an error in extension. The Adjusted Trial Balance columns formulate the next step of sorting the amounts to the Statement of Retained Earnings, the Income Statement and the Balance Sheet columns much easier.
