Problem 5-24A Effect of inventory errors on financial statements LO 5-3

The following income statement was prepared for Frame Supplies for the year Year 1:

FRAME SUPPLIES
Income Statement
For the Year Ended December 31, Year 1
Sales	$	73,900
Cost of goods sold		(36,320	)
Gross margin		37,580
Operating expenses		(8,775	)
Net income	$	28,805

During the year-end audit, the following errors were discovered:

1. An $1,230 payment for repairs was erroneously charged to the Cost of Goods Sold account. (Assume that the perpetual inventory system is used.)
2. Sales to customers for $2,021 at December 31, Year 1, were not recorded in the books for Year 1. Also, the $1,264 cost of goods sold was not recorded.
3. A mathematical error was made in determining ending inventory. Ending inventory was understated by $1,376. (The Inventory account was mistakenly written down to the Cost of Goods Sold account.)

Required Determine the effect, if any, of each of the errors on the following items. Give the dollar amount of the effect and whether it would overstate (O), understate (U), or not affect (NA) the account. The first item for each error is recorded as an example.
