Problem #1

Prepare comparative income statements similar to the ones found in your text at Exhibit 6.8 for the three inventory cost flow methods of FIFO, LIFO and weighted average. The company uses a perpetual inventory system and its income tax rate is 30%.

In calculating cost of sales, be sure to demonstrate the flow of inventory during the year and prove your ending inventory amount by using the inventory cost formula (BI + Purchases = GA EI = CGS).

Problem #2

Discuss in 500 words or less how the financial results from using the three alternative methods would change if Sarah Perreault had been experiencing declining costs in its purchases of inventory?

Problem #3

What advantages and disadvantages are offered by using LIFO and FIFO? Assume the continuing trend of increasing costs.
