Henry Mills is responsible for preparing checks, recording cash disbursements, and preparing bank reconciliations for Signet Corporation. While reconciling the October bank statement, Mills noticed that several checks totaling $937 had been outstanding for more than one year. Concluding that these checks would never be presented for payments, Mills prepared a check for $937 payable to himself, forged the treasurer's signature, and cashed the check. Mills made no entry in the accounts for this disbursement and attempted to conceal the theft by destroying the forged check and omitting the long-outstanding checks from subsequent bank reconciliations. Whatsthe weakness of Signet Corporation's internal control?
