Revision question on internal control and internal control deficiencies NBAA May 2019

Al-amry Co. ‘owns’ and operates an electric power station, which produces electricity 24 hours a day, seven days a week. The Company’s year end is 30th June.

You are an audit manager of Hickman & Associates, the auditors of Alamy Co. The interim audit has been completed and you are reviewing the documentation describing Al-amry Co’s payroll system. Payroll Systems notes Al-amry Co employs over 250 people and approximately 70% of the employees work in production at the power station. There are three shifts every day with employees working eight hours each. The production employees are paid weekly in cash. The remaining 30% of employees work at the head office in non-production roles and are paid monthly by bank transfer. The Company has a Human Resources (HR) Department, responsible for setting up all-new employees’ records. Pre-printed forms are completed by HR for all new employees and, once verified, a copy is sent to the Payroll Department for the employee to be included in the payroll for payment. This form includes the staff employees number and employees’ payroll cannot set up new department without this information. To encourage staff to attend work on time for all shifts, Al-amry Co. introduced a discretionary bonus, paid every three months, for production staff. The production supervisors determine the amounts to be paid and notify the Payroll Department. This quarterly bonus is entered into the system by a clerk and each entry is checked by a senior clerk for input errors prior to processing. The senior clerk signs the bonus listing as evidence of undertaking this review. Production employees are issued with clock cards and are required to swipe their cards at the beginning and at the end of their shift. This process is supervised by security staff 24 hours a day. Each card identifies the employee’s number and links it with the hours worked report produced by the payroll system, which automatically calculates the gross and net pay along with relevant deductions. These calculations are not checked. In addition to tax deductions from payroll, some employee’s wages are reduced for such items as repayments of student loans owed to the central government. All employers have a statutory obligation to remit funds on timely basis and to maintain accounting records which reconcile with annual loan statements sent by the government to employers. At Al-amry Co. student loan deduction forms are completed by the relevant employee and payments are made directly to the government until the employee notifies HR that the loan has been repaid in full.

On a quarterly basis, exception reports relating to changes to the payroll standing data are produced and reviewed by the payroll director. No overtime is worked by employees. Employees are entitled to take 28 days to leave annually. Holiday request forms are required to be completed and authorized by relevant line managers, however, this does not always occur. On a monthly basis, for employees paid by bank transfer, the senior payroll manager reviews the list of bank payments and agrees on this to the payroll records prior to authorizing the payment. If any errors are noted, the payroll senior manager amends the records. For production employees paid in cash, the necessary amount of cash is delivered weekly from the bank by a security Company. Two members of the Payroll Department arranges the pay packets, where one is responsible for preparing the pay packets and the other checks and verify them. Both members of staff are required to sign the weekly payroll listing on completion of this task. The pay packets are then delivered to the production supervisors, who distribute them to employees at the end of the week, as they know each member of their production team. Monthly management accounts are produced which details variances between budgeted amounts and actual. Revenue and key production costs are detailed, however, as there are no overtime costs, wages and salaries are not analyzed.
