Final answer:
The $59,900 difference between the cost and sales price of the stock should be recorded as a deduction from retained earnings.
Step-by-step explanation:
The $59,900 difference between the cost and sales price should be recorded as a deduction from retained earnings. This is because the treasury stock account is a component of retained earnings, and any gains from sales of the same class of stock are added to retained earnings. Therefore, the difference should be deducted from retained earnings unless there are previous net gains from sales of the same class of stock included in Additional Paid-in Capital, in which case it should be deducted from Additional Paid-in Capital to the extent that previous net gains are included.
