Internal Control of Cash Payments Paragon Tech Company, a communications equipment manufacturer, recently fell victim to a fraud scheme developed by one of its employees. To understand the scheme, it is necessary to review Paragon Tech's procedures for the purchase of services. The purchasing agent is responsible for ordering services (such as repairs to a photocopy machine or office cleaning) after receiving a service requisition from an authorized manager. However, because no tangible goods are delivered, a receiving report is not prepared. When the Accounting Department receives an invoice billing Paragon Tech for a service call, the accounts payable derk calls the manager who requested the service in order to verify that it was performed. The fraud scheme involves Mae Jansma, the manager of plant and facilities. Mae arranged for her uncle's company, Radiate Systems, to be placed on Paragon Tech's approved vendor list. Mae did not disclose the family relationship. On several occasions, Mae would submit a requisition for services to be provided by Radiate Systems. However, the service requested was really not needed, and it was never performed. Radiate Systems would bill Paragon Tech for the service and then split the cash payment with Mae. What changes should be made to Paragon Tech's procedures for ordering and paying for services in order to prevent such occurrences in the future? a. Someone other than the purchasing agent should be responsible for ordering service b. Employees should be required to disclose relationships between themselves and vendors, c. Paragon Tech must separate responsibilities for related operations. d. All of these choices are correct. e. None of these choices are correct
