such distribution in cash or its equivalent shall be treated for the purposes of this subparagraph as made during such year.

(D) Reduction in distribution amount 
If, during the taxable years in the adjustment period for which the organization is a private foundation, the foundation distributes amounts in cash or its equivalent which exceed the amount required to be distributed under clause (ii)(II) of subparagraph (B) (including but not limited to payments with respect to set-asides which were treated as qualifying distributions in prior years), then for purposes of this subsection the distribution required under clause (ii)(II) of subparagraph (B) for the taxable year shall be reduced by an amount equal to such excess.

For purposes of this section
(1) In general 
The term excess business holdings means, with respect to the holdings of any private foundation in any business enterprise, the amount of stock or other interest in the enterprise which the foundation would have to dispose of to a person other than a disqualified person in order for the remaining holdings of the foundation in such enterprise to be permitted holdings.

The permitted holdings of any private foundation in an incorporated business enterprise are
(i) 20 percent of the voting stock, reduced by

(i) during the 20-year period beginning on such date, if the private foundation and all disqualified persons have more than a 95 percent voting stock interest on such date,
(ii) except as provided in clause (i), during the 15-year period beginning on such date, if the foundation and all disqualified persons have more than a 75 percent voting stock interest (or more than a 75 percent profits or beneficial interest in the case of any unincorporated enterprise) on such date or more than a 75 percent interest in the value of all outstanding shares of all classes of stock (or more than a 75 percent capital interest in the case of a partnership or joint venture) on such date, or

Except as provided in paragraph (5), if, after May 26, 1969, there is a change in the holdings in a business enterprise (other than by purchase by the private foundation or by a disqualified person) which causes the private foundation to have
(A) excess business holdings in such enterprise, the interest of the foundation in such enterprise (immediately after such change) shall (while held by the foundation) be treated as held by a disqualified person (rather than by the foundation) during the 5-year period beginning on the date of such change in holdings; or
(B) an increase in excess business holdings in such enterprise (determined without regard to subparagraph (A)), subparagraph (A) shall apply, except that the excess holdings immediately preceding the increase therein shall not be treated, solely because of such increase, as held by a disqualified person (rather than by the foundation).

In any case where an acquisition by a disqualified person would result in a substitution under clause (i) or (ii) of subparagraph (D) of paragraph (4), the preceding sentence shall be applied with respect to such acquisition as if it did not contain the phrase or by a disqualified person in the material preceding subparagraph (A).

(i) diligent efforts to dispose of such holdings have been made within the initial 5-year period, and
