1) A bank reconciliation statement reconciles the difference between the bank balance in a company's cash book and the bank balance in its bank statement. 2) Differences can arise due to timing delays in transactions being recorded or errors made by the business or bank. Timing differences include cheques that have not cleared and deposits not yet processed. 3) The bank reconciliation statement lists transactions that increase or decrease the cash book balance to reconcile it with the bank statement balance. Preparing this statement verifies the accuracy of both records.
