(D) Antiabuse rules The Secretary may issue regulations or other guidance which prevent the avoidance of the purposes of subparagraph (A), including regulations or other guidance which treat convertible and contingent debt (and other debt having the attributes of equity) as a capital interest in the partnership. (E) Controlled groups of entities (i) In general In the case of a controlled group of entities, if an interest in the partnership received in exchange for a contribution to the capital of the partnership by any member of such controlled group would (in the hands of such member) constitute property held in connection with a trade or business, then any interest in such partnership held by any member of such group shall be treated for purposes of subparagraph (A) as constituting (in the hands of such member) property held in connection with a trade or business. (ii) Controlled group of entities For purposes of clause (i), the term controlled group of entities means a controlled group of corporations as defined in section 1563(a)(1), applied without regard to subsections (a)(4) and (b)(2) of section 1563.

(C) Allocations to service providers’ qualified capital interests which are less than other allocations Allocations shall not be treated as failing to meet the requirement of paragraph (1)(A) merely because the allocations to the qualified capital interest represent a lower return than the allocations made to the other qualified capital interests referred to in such paragraph. (3) Special rule for changes in services and capital contributions In the case of an interest in a partnership which was not an investment services partnership interest and which, by reason of a change in the services with respect to assets held (directly or indirectly) by the partnership or by reason of a change in the capital contributions to such partnership, becomes an investment services partnership interest, the qualified capital interest of the holder of such partnership interest immediately after such change shall not, for purposes of this subsection, be less than the fair market value of such interest (determined immediately before such change).

(5) Exception for no-self-charged carry and management fee provisions Except as otherwise provided by the Secretary, an interest shall not fail to be treated as satisfying the requirement of paragraph (1)(A) merely because the allocations made by the partnership to such interest do not reflect the cost of services described in subsection (c)(2) which are provided (directly or indirectly) to the partnership by the holder of such interest (or a related person). (6) Special rule for dispositions In the case of any investment services partnership interest any portion of which is a qualified capital interest, subsection (b) shall not apply to so much of any gain or loss as bears the same proportion to the entire amount of such gain or loss as— (A) the distributive share of gain or loss that would have been allocated to the qualified capital interest (consistent with the requirements of paragraph (1)) if the partnership had sold all of its assets at fair market value immediately before the disposition, bears to (B) the distributive share of gain or loss that would have been so allocated to the investment services partnership interest of which such qualified capital interest is a part.
