Final answer:
In year 1, Wildcat Corporation would treat $100,000 of the $300,000 distribution as a dividend, due to the availability of accumulated E&P at the beginning of the year and the negative current E&P.
Step-by-step explanation:
The amount of the distribution treated as a dividend for Wildcat Corporation in year 1 would be $100,000. This is because dividends are paid out of the current and accumulated E&P (Earnings and Profits). Since the current E&P is negative $200,000 and there's an accumulated E&P of $100,000 at the beginning of the year, only the accumulated E&P is available to be distributed as a dividend. Therefore, the distribution up to this amount ($100,000) is considered a dividend. The remaining $200,000 of the distribution is not treated as a dividend, and could potentially be a return of capital or capital gain.
