Case 3 A. The Nyameye Company, a client of your firm, has come to you with the following problem. It has three clerical employees who must perform the following functions: Maintain the general ledger Maintain the accounts payable ledger Maintain the accounts receivable ledger Prepare checks for signature Maintain the cash disbursements journal Issue credits on returns and allowances Reconcile the bank account Handle and deposit cash receipts Assuming equal abilities among the three employees, the company asks you to assign the eight functions to them to maximize internal control. Assume that these employees will perform no accounting functions other than the ones listed. Required: i. List three possible unsatisfactory pairings of the functions. ii. State how you would distribute the functions among the three employees. Assume that apart from the nominal jobs of the bank reconciliation and the issuance of credits on returns and allowances, all functions require an equal amount of time. B) Your current system is deemed to be 90% reliable. A major threat has been identified with an impact of GHS3,000,000. Two control procedures exist to deal with the threat. Implementation of control A would cost GHS100,000 and reduce the likelihood to 6%. Implementation of control B would cost GHS140,000 and reduce the likelihood to 4%. Implementation of both controls would cost GHS220,000 and reduce the likelihood to 2%. Required: Given the data, and based solely on an economic analysis of costs and benefits, what should you do?
