Instructions

1. Determine the cost of the inventory on October 31, 2014, by the first-in, first-out method. Present data in columnar form, using the following headings:
           Model       Quantity       Unit Cost          Total Cost
If the inventory of a particular model comprises one entire purchase plus a portion
of another purchase acquired at a different unit cost, use a separate line for each
purchase.

2. Determine the cost of the inventory on October 31, 2014, by the last-in, first-out method, following the procedures indicated in (1).

3. Determine the cost of the inventory on October 31, 2014, by the weighted average
cost method, using the columnar headings indicated in (1).

4. Discuss which method (FIFO or LIFO) would be preferred for income tax
purposes in periods of (a) rising prices and (b) declining prices.


Answer:




3. Weighted Average Cost Method
Model Quantity Unit Cost* Total Cost
A10 6 $ 70 $ 420
B15 8 174 1,392
E60 5 69 345
G83 9 253 2,277
J34 15 258 3,870
M90 5 121 605
Q70 8 172 1,376
Total $10,285
* Computations of unit costs:
A10: $70 = [(4 × $64) + (4 × $70) + (4 × $76)] ÷ (4 + 4 + 4)
B15: $174 = [(8 × $176) + (4 × $158) + (3 × $170) + (6 × $184)] ÷ (8 + 4 + 3 + 6)
E60: $69 = [(3 × $75) + (3 × $65) + (15 × $68) + (9 × $70)] ÷ (3 + 3 + 15 + 9)
G83: $253 = [(7 × $242) + (6 × $250) + (5 × $260) + (10 × $259)] ÷ (7 + 6 + 5 + 10)
J34: $258 = [(12 × $240) + (10 × $246) + (16 × $267) + (16 × $270)] ÷ (12 + 10 + 16 + 16)
M90: $121 = [(2 × $108) + (2 × $110) + (3 × $128) + (3 × $130)] ÷ (2 + 2 + 3 + 3)
Q70: $172 = [(5 × $160) + (4 × $170) + (4 × $175) + (7 × $180)] ÷ (5 + 4 + 4 + 7)








4.
a. During periods of rising prices, the LIFO method will result in a lower cost of inventory, a greater amount of cost of merchandise sold, and a lesser amount of net income than the other two methods. For Dymac Appliances, the LIFO method would be preferred for the current year, since it would result in a lesser amount of income tax.

b. During periods of declining prices, the FIFO method will result in a lesser amount of net income and would be preferred for income tax purposes
