Answer:
$16,000
Step-by-step explanation:
Given that,
Cost of investment in equity securities on December 31, 2017 = $510,000 and Fair value = $488,000
Fair value of the securities on December 31, 2018 = $504,000
Unrealized gain:
= Fair value of the securities on December 31, 2018 - Fair value of investment at December 31, 2017
= $504,000 - $488,000
= $16,000
Therefore, the Oriole should report unrealized gain of $16,000 on its 2018 income statement as a result of the increase in fair value of the investments in 2018.
