Answer:
Sam must report $700,000 distribution from Silver on his Income report.
Explanation:
The sale of the land is made by the corporation and the corporation is a tax payer therefore any gains and losses are for the company to pay tax on.
The deficits in the E&P are for Silver to take into account when about to pay taxes.
The basis of $200,000 is not income but cost and subtracted on the distribution income as is for Sam.
