Final answer:
Hawk Corporation would report a capital gain of $20 per share for the sale of the Diamond Corporation stock in its 2013 income statement.
Step-by-step explanation:
In its 2013 income statement, Hawk Corporation would report a capital gain of $20 per share for the sale of the Diamond Corporation stock.
To calculate this, we subtract the purchase price per share ($50) from the selling price per share ($70). So, the capital gain per share is $70 - $50 = $20.
Since Hawk sold all 10,000 shares, the total capital gain reported in its income statement would be $20 per share * 10,000 shares = $200,000.
