unrelated business taxable income
(A)In the case of an organization described in paragraph (7), (9), or (17) of section 501(c), the term “unrelated business taxable income” means the gross income (excluding any exempt function income), less the deductions allowed by this chapter which are directly connected with the production of the gross income (excluding exempt function income), both computed with the modifications provided in paragraphs (6), (10), (11), and (12) of subsection (b). For purposes of the preceding sentence, the deductions provided by sections 243 and 245 (relating to dividends received by corporations) shall be treated as not directly connected with the production of gross income.
