Final Answer:
Jeremiah Corporation will report a total gain of $7,000 in the December 31, 2013, income statement relative to the portfolio.
Step-by-step explanation:
To calculate the gain, you subtract the cost of each security from its fair value. For Security A, the gain is $4,900 - $4,000 = $900. For Security B, the gain is $66,000 - $70,000 = -$4,000 (note: this is a loss). For Security C, the gain is $39,000 - $28,000 = $11,000. Adding up these gains and losses: $900 - $4,000 + $11,000 = $7,000 gain.
It's important to note that, despite the decline in the fair value of Security B, it is considered a temporary decline. Therefore, the losses are not realized, and only the gains are reported on the income statement.
