The pro rata share referred to in subsection (a) in the case of any shareholder is the amount which would have been distributed with respect to the shareholder’s stock if, on each day during the taxable year of the fund, the fund had distributed to each shareholder a pro rata share of that day’s ratable share of the fund’s ordinary earnings and net capital gain for such year. To the extent provided in regulations, if the fund establishes to the satisfaction of the Secretary that it uses a shorter period than the taxable year to determine shareholders’ interests in the earnings of such fund, pro rata shares may be determined by using such shorter period.
If the taxpayer establishes to the satisfaction of the Secretary that any amount distributed by a passive foreign investment company is paid out of earnings and profits of the company which were included under subsection (a) in the income of any United States person, such amount shall be treated, for purposes of this chapter, as a distribution which is not a dividend; except that such distribution shall immediately reduce earnings and profits. If the passive foreign investment company is a controlled foreign corporation (as defined in section 957(a)), the preceding sentence shall not apply to any United States shareholder (as defined in section 951(b)) in such corporation, and, in applying section 959 to any such shareholder, any inclusion under this section shall be treated as an inclusion under section 951(a)(1)(A).
The earnings and profits of any qualified electing fund shall be determined without regard to paragraphs (4), (5), and (6) of section 312(n). Under regulations, the preceding sentence shall not apply to the extent it would increase earnings and profits by an amount which was previously distributed by the qualified electing fund.
