Detailed Answer
Answer (B) is correct.
A realized loss or gain is recognized when an individual security is sold
or otherwise disposed of. The investment was acquired for $40 per share.
Because the shares were purchased as a long-term investment, they
should be classified as available-for-sale securities. Thus, the temporary
decline in fair value at 12/31/Year 1 was debited to other comprehensive
income and was not included in earnings. Accordingly, the realized loss
included in earnings at 12/31/Year 2 was $80,000 [8,000 shares � ($40 �
$30)].
