Response to the following problem:
The following misstatements are included in the accounting records of Westgate Manufacturing Company.
1. Each month, a fraudulent receiving report is submitted to accounting by an employee in the receiving department. A few days later, he sends Westgate an invoice for the quantity of goods ordered from a small company he owns and operates in the evening. A check is prepared, and the amount is paid when the receiving report and the vendor's invoice are matched by the accounts payable clerk.
2. Telephone expense (account 2112) was unintentionally charged to repairs and maintenance (account 2121).
3. The accounts payable clerk prepares a monthly check to Story Supply Company for the amount of an invoice owed and submits the unsigned check to the treasurer for payment along with related supporting documents that have already been approved. When she receives the signed check from the treasurer, she records it as a debit to accounts payable and deposits the check in a personal bank account for a company named Story Company. A few days later, she records the invoice in the acquisitions journal again, resubmits the documents and a new check to the treasurer, and sends the check to the vendor after it has been signed.
4. The amount of a check in the cash disbursements journal is recorded as $4,612.87 instead of $6,412.87.
5. The accounts payable clerk intentionally excluded from the cash disbursements journal seven large checks written and mailed on December 26 to prevent cash in the bank from having a negative balance on the general ledger. They were recorded on January 2 of the subsequent year.
6. Acquisitions of raw materials are often not recorded until several weeks after the goods are received because receiving personnel fail to forward receiving reports to accounting. When pressure from a vendor's credit department is put on Westgate's accounting department, it searches for the receiving report, records the transactions in the acquisitions journal, and pays the bill.
