Realized Gain 은 Income statement에 어디에 보고 되나요?

a 24.***.59.88

문제 올릴게요

Beginning inventory: 800 units
Units purchased during the year: 3000 units
ending inventory 900 units
current cost per unit of inventory $52 at 1/1, $60 at 12/31
At 12/31, the selling price per unit was $85

Income statement
-COGS in I/S: $160,000
-Income from continuing operations before tax: $800,000

Balance sheet
-inventory: $50,000

Prepare voluntary supplementary information restated into current cost

(1) Unrealized holding gain 은 ending inventory at current cost로 하면 $54,000 – 50,000 = 4000
그래서 이건 balance sheet 의 AOCI로 가고 (확인 부탁드려요)

(2) realized holding gain 은 cogs at current cost 는 2900*$56 = $162,400 – 160,000 = 2400 이 나오는건 이해가 가요

그런데 결국

(3) Income from continuing operations = 800,000-2400 = 797,600이 되는게 이해가 안가요. 일단 unrealized gain은 income statement로 가지 않기 때문에 제외시키는 것인거 같은데 2400은 왜 빼줘야되나요?
