Answer:
On 12/31/17, Roger Corporation should report accumulated other comprehensive income of $13 million
Explanation:
Accumulated other comprehensive income account is the port equity section in the balance sheet and it reports the accumulated unrealized gains / losses of the company.
Accumulated Comprehensive income account:
Opening balance on 12/31/16 = $10 million
Additions for the year ( $15 - $12 ) = $3 million
Opening balance on 12/31/17 = $13 million
Net income will be added to retained earning. The Value of total comprehensive income is divided in two parts first Net income and second other comprehensive income. Net income will be transferred to retained earning account and other comprehensive to accumulative comprehensive income account.
