Final answer:
The corporation's current earnings and profit for 20x3 would be -$480,000.
Step-by-step explanation:
To determine the corporation's current earnings and profit for 20x3, we need to consider the net operating loss and the disallowed expenses and income. The net operating loss of $500,000 in 20x3 indicates that the corporation's expenses exceeded its revenues for that year. However, the disallowed meals and entertainment expense of $20,000 should be added back to the net operating loss to calculate the current earnings and profit.
Therefore, the current earnings and profit for 20x3 can be calculated as follows:
Net operating loss: -$500,000
Add back disallowed expense: +$20,000
Current earnings and profit: -$500,000 + $20,000 = -$480,000
