(f) Treatment of earnings received after patronage occurred
If any portion of the earnings from business done with or for patrons is includible in the organization's gross income for a taxable year after the taxable year during which the patronage occurred, then for purposes of applying paragraphs (1) and (2) of subsection (b) to such portion the patronage shall, to the extent provided in regulations prescribed by the Secretary, be considered to have occurred during the taxable year of the organization during which such earnings are includible in gross income.
