(a) Partners
In the case of a distribution by a partnership to a partner—

(1) gain shall not be recognized to such partner, except to the extent that any money distributed exceeds the adjusted basis of such partner's interest in the partnership immediately before the distribution, and

(2) loss shall not be recognized to such partner, except that upon a distribution in liquidation of a partner's interest in a partnership where no property other than that described in subparagraph (A) or (B) is distributed to such partner, loss shall be recognized to the extent of the excess of the adjusted basis of such partner's interest in the partnership over the sum of—

(A) any money distributed, and

(B) the basis to the distributee, as determined under section 732, of any unrealized receivables (as defined in section 751(c)) and inventory (as defined in section 751(d)).

Any gain or loss recognized under this subsection shall be considered as gain or loss from the sale or exchange of the partnership interest of the distributee partner.

(3) Exceptions

(A) In general
Paragraph (1) shall not apply to the distribution from a partnership of a marketable security to a partner if—

(ii) to the extent provided in regulations prescribed by the Secretary, the property was not a marketable security when acquired by such partnership, or

(iii) such partnership is an investment partnership and such partner is an eligible partner thereof.

(B) Limitation on gain recognized
In the case of a distribution of marketable securities to a partner, the amount taken into account under paragraph (1) shall be reduced (but not below zero) by the excess (if any) of—

(i) such partner's distributive share of the net gain which would be recognized if all of the marketable securities of the same class and issuer as the distributed securities held by the partnership were sold (immediately before the transaction to which the distribution relates) by the partnership for fair market value, over

(ii) such partner's distributive share of the net gain which is attributable to the marketable securities of the same class and issuer as the distributed securities held by the partnership immediately after the transaction, determined by using the same fair market value as used under clause (i).

Under regulations prescribed by the Secretary, all marketable securities held by the partnership may be treated as marketable securities of the same class and issuer as the distributed securities.

(C) Definitions relating to investment partnerships
For purposes of subparagraph (A)(iii):

(i) Investment partnership

(iv) Look-thru of partnership tiers
Except as otherwise provided in regulations prescribed by the Secretary—

(II) a partner who contributes to a partnership an interest in another partnership shall be treated as contributing a proportionate share of the assets of the other partnership.

 If the preceding sentence does not apply under such regulations with respect to any interest held by a partnership in another partnership, the interest in such other partnership shall be treated as if it were specified in a subclause of clause (i).
