If a private foundation invests any amount in such a manner as to jeopardize the carrying out of any of its exempt purposes, there is hereby imposed on the making of such investment a tax equal to 10 percent of the amount so invested for each year (or part thereof) in the taxable period. The tax imposed by this paragraph shall be paid by the private foundation.
In any case in which a tax is imposed by paragraph (1), there is hereby imposed on the participation of any foundation manager in the making of the investment, knowing that it is jeopardizing the carrying out of any of the foundation’s exempt purposes, a tax equal to 10 percent of the amount so invested for each year (or part thereof) in the taxable period, unless such participation is not willful and is due to reasonable cause. The tax imposed by this paragraph shall be paid by any foundation manager who participated in the making of the investment.
In any case in which an initial tax is imposed by subsection (a)(1) on the making of an investment and such investment is not removed from jeopardy within the taxable period, there is hereby imposed a tax equal to 25 percent of the amount of the investment. The tax imposed by this paragraph shall be paid by the private foundation.
In any case in which an additional tax is imposed by paragraph (1), if a foundation manager refused to agree to part or all of the removal from jeopardy, there is hereby imposed a tax equal to 5 percent of the amount of the investment. The tax imposed by this paragraph shall be paid by any foundation manager who refused to agree to part or all of the removal from jeopardy.
For purposes of this section, investments, the primary purpose of which is to accomplish one or more of the purposes described in section 170(c)(2)(B), and no significant purpose of which is the production of income or the appreciation of property, shall not be considered as investments which jeopardize the carrying out of exempt purposes.
An investment which jeopardizes the carrying out of exempt purposes shall be considered to be removed from jeopardy when such investment is sold or otherwise disposed of, and the proceeds of such sale or other disposition are not investments which jeopardize the carrying out of exempt purposes.
