De La Salle University Problems on Accounting for Raw Materials

M. GUIA/E. MAGCALE

Problem 1 (Re-Order Point): Assume that the expected daily usage of an item of materials is 100 units. The anticipated lead time is 4 days, and it is estimated that a safety stock of 800 units is needed. Required: Compute for the Re-Order Point. Problem 2 (EOQ): The following information pertains to a particular inventory of materials: Ordering Costs P 10.00/order Carrying Costs of Inventory P 0.80/unit Annual Demand for Raw Materials 10,000 units Required: 1. Using the tabular method and the following order sizes, compute the EOQ of the raw material: (100, 300, 500, 700, and 900 units) 2. Using the formula method, compute for the EOQ Problem 3 (EOQ and Re-Order Point): A television manufacturer buys wooden cabinet from outside suppliers at P 400 per set. Total annual needs are 5,000 units at a rate of 20 sets per working day. The following cost data are available: Desired annual returns on inventory investment (10% @ P400) P 40 Rent, Insurance, and Taxes per unit P 10 Total Annual Carrying Costs per unit P 50 Ordering Costs P 50 Required: 1. Using the tabular method and the following order sizes, compute the EOQ of the raw materials: (20, 40, 50, 100, 200, 300) 2. Using the formula method, compute for the EOQ 3. Using the computed EOQ, compute the Annual ordering costs and annual carrying costs. 4. Assuming a lead time of 3 days with no desired safety stock, what will be the company’s reorder point? Problem 4 (Costing Methods): Assume the following information for a particular inventory: August 1: Inventory 400 units @ P10 P 4,000 12 Purchase 600 units @ P 12 7,200 16 Issue 500 units 18 Purchase 300 units @ P 15 4,500 20 Issue 200 units 25 Purchase 400 units @ P 14 5,600 28 Issue 400 units Required: Compute for both the value of ending inventory and cost of materials used/issued using: 1. Periodic – FIFO 2. Perpetual – FIFO 3. Periodic – Average (Weighted Average) 4. Perpetual – Average (Moving Average) Problem 5 (Costing Methods) The Heaven and Earth made the following materials purchases and issues during January: January 1 Balance on hand 1,000 units @ P4.00 each 3 Issued 250 units 5 Received 500 units @ P4.50 each 6 Issued 150 units 10 Issued 110 units 11 Factory returned 10 units to the store room that were issued on the 10th 15 Received 500 units @ P5.00 each 20 Returned 300 units to vendor from January 15th purchases 26 Issued 100 units

De La Salle University Required: Compute for both the value of ending inventory and cost of materials used/issued using: 1. Periodic – FIFO 2. Perpetual – FIFO 3. Periodic – Average (Weighted Average) 4. Perpetual – Average (Moving Average) Problem 6 (Discounts): The Jenelle Company purchase materials listed at P 40,000; terms 2/15, n/30 on August 1: Required: Journal entries to record the purchase and payments assuming (a.) Full payment is made on August 14, (b.) Full payment is made on August 30 using the following: 1. Gross Method 2. Net Method 3. Allowance Method Problem 7 (Discounts): On January 1, Baxter Corporation purchase materials listed at P 400,000 while receiving a trade discounts of 10%, and 5%, while the credit term is 5/10, n/30. Required: Journal entries to record the purchase and payments assuming (a.) Full payment is made on January 9, (b.) Full payment is made on January 30 using the following: 1. Gross Method 2. Net Method 3. Allowance Method Problem 8 (Freight): An invoice for raw materials A, B, and C is received from the Bulacan Corporation. The invoice totals are: A – P 25,000; B – P 15,000; and C – P 10,000. The freight charge on this shipment weighing 10,000 pounds is P 1,500. Shipping weights for the respective materials are 5,000; 2,000, and 1,000 respectively. Required: Record the purchase and freight using: 1. Direct Charging a. Relative Peso Value Method b. Relative Weight Method 2. Indirect Charging Problem 9 (Periodic): Adrian Taylor Corporation is a newly formed entity that engages in the purchase and resale of amphibious tour vehicles. Purchases for the first year of operation were as follows: Date Purchases 7-Jan 50 units @ P 15,000 each 15-Mar 70 units @ P 16,000 each 16-Jun 30 units @ P 16,500 each 3-Aug 90 units @ P 17,000 each 11-Oct 25 units @ P 17,200 each Sales for this first year of operation amounted to 210 units and totaled P 4,250,000. (a) If Adrian Taylor uses the first-in, first-out (FIFO) inventory method (periodic approach), what values would be assigned to ending inventory and cost of goods sold? How much is gross profit? (b) If Adrian Taylor uses the last-in, first-out (LIFO) inventory method (periodic approach), what values would be assigned to ending inventory and cost of goods sold? How much is gross profit? (c) If Adrian Taylor uses the weighted-average inventory method (periodic approach), what values would be assigned to ending inventory and cost of goods sold? How much is gross profit? Problem 10 (EOQ): An auto parts supplier sells Hardy-brand batteries to car dealers and auto mechanics. The annual demand is approximately 1,200 batteries. The supplier pays P28.00 for each battery and estimates that the annual holding cost is 30 percent of the battery's value. It costs

De La Salle University approximately P20 to place an order (managerial and clerical costs). The supplier currently orders 100 batteries per month. Required: a. Determine the ordering, holding, and total inventory costs for the current order quantity. b. Determine the economic order quantity (EOQ). c. How many orders will be placed per year using the EOQ? d.

During the month, the company cut and assembled 8,000 golf jackets. One hundred of the jackets did not meet specifications and were considered “seconds”. Seconds are sold for P 80.00 per jacket, whereas first quality jackets sell for P 399.50.
