Answer:
An unrealized holding gain of $28 million in 2019.
Step-by-step explanation:
At the financial year-end, the company have to reevaluate the investment to recognize the gain or loss.
If the fair value is higher than actual investment, the company gain and vice versa it lost.
In this scenario, the fair value adjustment = the valuation on 31st December – purchased value = $150 million - $132 million = $28 million.
Because this step is just an approach to record new valuation of investment, then it’s consider unrealized.
In short, Phillips Corporation should first update the fair value adjustment of $28 million on December 31 2021
