Roll Call manufactures a unique key chain with a built-in radio frequency identification chip. This device is issued to students at State University, and a host computer tracks student attendance at each class by automatically monitoring the whereabouts of the key chains. .

Roll Call’s ending inventory at December 31, 20X3 was \($1\),670,000. However, this value was transposed and entered into the accounting system at \($1\),760,000. As a result, ending inventory was overstated and cost of goods sold was understated by \($90\),000. This error was discovered in March of 20X4, when the CFO was preparing a presentation for potential investors.

The 20X3 books had long-since been closed, and financial reports were already released. The CFO proposed to correct the error by debiting Cost of Goods Sold and crediting Inventory for \($90\),000. Net income for 20X3 was \($900\),000, and 20X4 should be at about the same level.

(a) What is the appropriate journal entry to correct the error? You may assume the firm uses a periodic inventory system, and the balance of the Inventory account is shown as \($1\),760,000.

(b) In the CFO presentation to potential investors, how much should be reported as 20X3 net income?

How much should be reported as inventory on hand at December 31, 20X3?
