Answer:
Blue Co. should report $100,000 gain.
Step-by-step explanation:
The difference between the carrying value of shares and Market value of shares is the gain / loss which Blue Co. should report before income taxes on disposal of the stock.
Carrying Value = 200,000 x $2 = $400,000
Market Value = 200,000 x $2.5 = $500,000
Gain = Market Value - Carrying Value
Gain = $500,000 - $400,000
Gain = $100,000
