Treas. Reg. § 1.301-1(f), Example 2
Section 301 Distribution — Less Than E&P Results in Dividend Only
Corporation W owns 100% of Corporation M, which distributes property worth $25,000 — $10,000 in cash plus securities with a $15,000 adjusted basis. Because the distribution is less than Corporation M’s earnings and profits of $26,000, the entire $25,000 is a dividend to Corporation W.
