As controller, you are responsible for the corporation's accounting recrods, preparation of the financial statements, safeguarding the corporate assets, and providing management with financial information to set prices and to monitor and control operations. Rockford Corporation closes its books annually on December 31 but prepares financial statements quarterly. Adjusting entries are posted to the general ledger only at year-end; at the end of the first, second, and third quarter the adjustments are entered only on a work sheet, not in the general ledger. Therefore, the adjusting entries to be recorded on December 31 are annual adjustments that you must journalize and the post to the general ledger accounts before preparing the financial statements. Rockford Corporation maintains a perpetual inventory system and takes a physical count each year to adjust the inventory carrying amount. Purchases are recorded at the gross amount (discounts taken are recognized at the date of payment) of the supplier's invoice, and the terms vary with each supplier. Sales on account are subject to terms of 2/10, n/30. Discounts are taken and granted only when the terms are met. The cost of all inventory sold in December was 70% of the sales price. In recording sales transactions, each sale should be posted on the day of the sale directly to the customer's account in the subsidiary ledger, using the invoice number as the posting reference number in the subsidiary account. Also, cash receipts from customers should be posted to the subsidiary ledger on the day they are received. The purchase order number should be used as the posting reference number in the subsidiary ledger for purchases on account from suppliers. Purchases from suppliers and payments to them should be posted daily. All other individual posting may be made weekly or at the month-end. Account numbers should be used as posting reference numbers in the journals. Officers and office personnel are salaried employees and are paid monthly on the last day of each month. The delivery truck drivers and warehouse employees are hourly wage employees and are paid biweekly. Each biweekly pay period ends Friday.
