7. 7 Under the gross price method, a company records the purchase at the gross price, and records the amount of the discount in the accounting system only if the discount is taken. Under the net price method, a company records the purchase at its net price, and records the amount of the discount in the accounting system only if the discount is not taken. Purchases Discounts

8. 8 Purchases Discounts- Gross Price Method To record the purchase Inventory (or Purchases)1,000 Accounts Payable1,000 A company purchases $1,000 of goods under terms of 1/10, n/30. To record payment within the discount period: Accounts Payable1,000 Purchases Discounts Taken10 Cash990 To record payment after the discount period: Accounts Payable1,000 Cash1,000

9. 9 To record the purchase: Inventory (or Purchases)990 Accounts Payable990 A company purchases $1,000 of goods under terms of 1/10, n/30. Purchases Discounts- Net Price Method To record payment within the discount period: Accounts Payable990 Cash990 To record payment after the discount period: Accounts Payable990 Purchases Discounts Lost10 Cash1,000 Purchases Discounts Lost are treated as a financing expense in the Other section of the income statement.

10. 10 Net Price Method Adjusting entry at the end of period if discount has expired and invoice is unpaid: Purchases Discounts Lost10 Accounts Payable10 A company purchases $1,000 of goods under terms of 1/10, n/30. Purchases Discounts

11. 11 If the company does not pay promptly, it is forfeiting 2% in order to keep the money for an additional 20 days. A company purchases $1,000 of goods under terms of 2/10, n/30. What is the annual discount rate? The company can forfeit this discount 18 times during a year. 360 days/ 20 additional each time = 18 Annual Rate on Discounts 2% forfeited 18 times equals an annual interest rate of 36%

24. 24 When a company initially changes to the LIFO method, the base year cost for the beginning of the year of change is the ending inventory for the prior year based on whatever method was used previously. Initial Adoption of LIFO

28. 28 1.The LIFO method requires a company to keep numerous detailed records. 2.Fluctuations in the physical quantities of similar inventory items may occur. 3.As technological changes take place, inventory made up with one material is replaced by inventory made with substitute materials or an outdated design is replaced by a newer design. Difficulties in Applying Simple LIFO

29. 29 Step 1: Value the total ending inventory at current- year costs. 01/1/06$10,000 12/31/06$12,100 12/31/07$13,125 12/31/08$16,800 12/31/09$12,360 Dollar-Value LIFO

30. 30 Step 2: Convert the ending inventory cost to base- year cost: 12/31/06$12,100 12/31/07$13,125 12/31/08$16,800 12/31/09$12,360 Ending Inventory at Current Cost x Base Year Cost Index Current Cost Index x100/110 = $11,000 12/31/06 Dollar-Value LIFO

31. 31 Step 3: Compute the change in the inventory level for the year at base-year costs. $11,000 $10,500 $12,000 $10,300 12/31/06 12/31/07 12/31/08 Base year, $10,000 $11,000 - $10,000 $1,000 1/1/06 12/31/06 Dollar Value LIFO

32. 32 Step 4a:If there has been an increase, convert this increase to current-year costs. Base year, $10,000 $1,000$1,000 12/31/06 x 110/100 =$ 1,100 x 100/100 =10,000 $11,100 Ending inventory, 12/31/06 Dollar-Value LIFO

33. 33 Step 2: Convert the ending inventory cost to base- year cost: 12/31/06$12,100 12/31/07$13,125 12/31/08$16,800 12/31/09$12,360 Ending Inventory at Current Cost x Base Year Cost Index Current Cost Index x100/110 = $11,000 x 100/125 = $10,500 12/31/07 Dollar-Value LIFO

34. 34 Step 3: Compute the change in the inventory level for the year at base-year costs. $11,000 $10,500 $12,000 $10,300 12/31/06 12/31/07 12/31/08 12/31/09 Base year, $10,000 12/31/07 $1,000 $11,000 - $10,500 Dollar-Value LIFO

35. 35 Step 3: Compute the change in the inventory level for the year at base-year costs. $11,000 $10,500 $12,000 $10,300 12/31/06 12/31/07 12/31/08 12/31/09 Base year, $10,000 12/31/07 $500 Dollar-Value LIFO

36. 36 Step 4b: If there is a decrease, this decrease reduces the inventory. Base year, $10,000 $500 12/31/07 x 110/100 =$ 550 x 100/100 =10,000 $10,550 Ending inventory, 12/31/07 Dollar-Value LIFO

37. 37 Step 2: Convert the ending inventory cost to base- year cost: 12/31/06$12,100 12/31/07$13,125 12/31/08$16,800 12/31/09$12,360 x110/100 = $11,000 x 100/125 = $10,500 x100/140 = $12,000 12/31/08 Dollar-Value LIFO Ending Inventory at Current Cost x Base Year Cost Index Current Cost Index

38. 38 Step 3: Compute the change in the inventory level for the year at base-year costs. $11,000 $10,500 $12,000 $10,300 12/31/06 12/31/07 12/31/08 12/31/09 Base year, $10,000 12/31/08 $500 $12,000 - $10,500 = $1,500 Dollar-Value LIFO

39. 39$500 $11,000 $10,500 $12,000 $10,300 12/31/06 12/31/07 12/31/08 12/31/09 Base year, $10,000 12/31/08 $1,500 Step 3: Compute the change in the inventory level for the year at base-year costs. Dollar-Value LIFO

40. 40 Step 4a:Convert increase to current-year costs. Base year, $10,000 12/31/08 x 140/100 =$ 2,100 x 110/100 = 550 x 100/100 =10,000 $12,650 Ending inventory, 12/31/08 $500 $1,500 Dollar-Value LIFO

41. 41 Step 2: Convert the ending inventory cost to base- year cost: 12/31/06$12,100 12/31/07$13,125 12/31/08$16,800 12/31/09$12,360 x110/100 = $11,000 x 100/125 = $10,500 x100/140 = $12,000 x100/120 = $10,300 12/31/09 Dollar-Value LIFO Ending Inventory at Current Cost x Base Year Cost Index Current Cost Index

45. 45 Step 4a:Convert increase to current-year costs. Base year, $10,000 12/31/09 x 110/100 = $ 330 x 100/100 =10,000 $10,330 Ending inventory, 12/31/09 $300 Dollar-Value LIFO

50. 50 1. An exchange gain occurs when the exchange rate declines between the date a payable is recorded as a result of a purchase of inventory and the date of the cash payment. 2. An exchange gain occurs when the exchange rate increases between the date a receivable is recorded as a result of a sale of inventory and the date of the cash receipt. When exchange rates are stated in terms of $ per unit of foreign currency, exchange gains and losses occur for purchases or sales on account as follows: ContinuedContinued Foreign Currency Transactions Involving Inventory

52. 52 A U.S. company purchases inventory of electronic components from a Japanese company for 50 million yen (¥) when the exchange rate is $0.008. ¥50,000,000 x $0.008 = $400,000 Inventory (or Purchases)400,000 Cash400,000 Foreign Currency Transactions Involving Inventory

53. 53 Assume that the exchange rate on the date of payment is $0.0078. The U.S. company has to pay only $390,000. ¥50,000,000 x $0.0078 = $390,000 Accounts Payable400,000 Cash390,000 Exchange Gain10,000 Foreign Currency Transactions Involving Inventory

54. 54 A U.S. company sells computer equipment (cost, $200,000) to a German Company on account and the agreed price is 300,000 euros. On the date of the sale, the exchange rate is $1.20 (1 euro = $1.20). €300,000 x $1.20 = $360,000 Accounts Receivable360,000 Sales Revenue360,000 Cost of Goods Sold200,000 Inventory200,000 Foreign Currency Transactions Involving Inventory
