Instructions

Address the following matters related to Robinson Co.s accounting for, and reporting of, its inventory activities during 2017 and 2018:

Compute the companys inventory at December 31, 2017 andits cost of goods sold for 2017 under each of the following cost flow methods:

FIFO method

LIFO method

Average cost method (round the average cost per unit to the nearest cent)

Compute the companys inventory at December 31, 2018 andits cost of goods sold for 2018 under each of the following cost flow methods:

FIFO method

LIFO method

Average cost method (round the average cost per unit to the nearest cent)

Assume Robinson uses a perpetual system and the FIFO method for day-to-day bookkeeping purposes, and the company converts its accounts to the LIFO method (periodic system) for financial reporting. Give the adjusting entry Robinson must make at December 31, 2017 to convert its accounts to LIFO. Ignore income taxes.

As in (c), assume Robinson keeps its accounts on a FIFO basis and converts them at year-end to the LIFO method. Give the adjusting entry needed at December 31, 2018 to convert the companys accounts to LIFO. Ignore income taxes. (Note Robinson follows the practice of making reversing entries to reverse the effects of certain prior-year adjusting entries. Proceed as if Robinson recorded an entry on January 1, 2018 to reverse the effects of the December 31, 2017 LIFO conversion entry. You do notneed to make this reversing entry; simply note that it has been made.)
