The management of Cary, Inc., wants you to review its controls over the process of raw materials purchase, receipt, and storage. You have prepared the following comments, which describe Cary's procedures. A) Raw materials, which consist mainly of high-cost electronic components, are kept in a locked storeroom. Storeroom personnel include a supervisor and four clerks. All are well trained, competent, and adequately bounded. Raw materials are removed from the storeroom only upon written or oral authorization of one of the production supervisors. B) There are no perpetual-inventory records; hence, the storeroom clerks do not keep records of goods received or issued To compensate for lack of perpetual records, a physical-inventory count is taken monthly by the storeroom clerks, who are well supervised. Appropriate procedures are followed in making the inventory count C) After the physical count the storeroom supervisor matches quantities counted against a predetermined recorderlevel. If the count for a given part is below the reorder, the supervisor enters the part number on a material requisition list and sends this list to the accounts payable clerk. The accounts payable clerk prepares a purchase order for a predetermined reorder quantity for each part and mails the purchase order to the vendor from whom the part was last purchased. D) When ordered materials arrive at Cary, they are received by the storeroom clerks. The clerks count the merchandise and agree the counts to the carrier's bill of lading. All bills of lading are initialed, dated, and filed in the storeroom to serve as receiving reports. Describe at least six major weaknesses in internal control and recommend improvements in Cary's procedures for the purchase, receipt, storage, and issuance of raw materials
