(d) Involvement of the partnership required. For purposes of section 7704(b) and this section, interests in a partnership are not traded on an established securities market within the meaning of paragraph (b)(5) of this section and are not readily tradable on a secondary market or the substantial equivalent thereof within the meaning of paragraph (c) of this section (even if interests in the partnership are traded or readily tradable in a manner described in paragraph (b)(5) or (c) of this section) unless—

(1) The partnership participates in the establishment of the market or the inclusion of its interests thereon; or

(iv) The closing of the sale effected by virtue of the matching service does not occur prior to the 45th calendar day after the date information regarding the offering of the interest for sale is made available to potential buyers and such time period is evidenced by contemporaneous records ordinarily maintained by the operator at a central location;

(v) The matching service displays only quotes that do not commit any person to buy or sell a partnership interest at the quoted price (nonfirm price quotes) or quotes that express interest in a partnership interest without an accompanying price (nonbinding indications of interest) and does not display quotes at which any person is committed to buy or sell a partnership interest at the quoted price (firm quotes);

(vi) The selling partner's information is removed from the matching service within 120 calendar days after the date information regarding the offering of the interest for sale is made available to potential buyers and, following any removal (other than removal by reason of a sale of any part of such interest) of the selling partner's information from the matching service, no offer to sell an interest in the partnership is entered into the matching service by the selling partner for at least 60 calendar days; and

(vii) The sum of the percentage interests in partnership capital or profits transferred during the taxable year of the partnership (other than in private transfers described in paragraph (e) of this section) does not exceed 10 percent of the total interests in partnership capital or profits.

(i) The passage of title to the partnership interest;

(ii) The payment of the purchase price (which does not include the delivery of funds to the operator of the matching service or other closing agent to hold on behalf of the seller pending closing); or

(iii) The date, if any, that the operator of the matching service (or any person related to the operator within the meaning of section 267(b) or 707(b)(1)) loans, advances, or otherwise arranges for funds to be available to the seller in anticipation of the payment of the purchase price.

(4) Optional features. A qualified matching service may be sponsored or operated by a partner of the partnership (either formally or informally), the underwriter that handled the issuance of the partnership interests, or an unrelated third party. In addition, a qualified matching service may offer the following features—

(i) The matching service may provide prior pricing information, including information regarding resales of interests and actual prices paid for interests; a description of the business of the partnership; financial and reporting information from the partnership's financial statements and reports; and information regarding material events involving the partnership, including special distributions, capital distributions, and refinancings or sales of significant portions of partnership assets;

(ii) The operator may assist with the transfer documentation necessary to transfer the partnership interest;

(iii) The operator may receive and deliver funds for completed transactions; and

(iv) The operator's fee may consist of a flat fee for use of the service, a fee or commission based on completed transactions, or any combination thereof.

(h) Private placements—(1) In general. For purposes of section 7704(b) and this section, except as otherwise provided in paragraph (h)(2) of this section, interests in a partnership are not readily tradable on a secondary market or the substantial equivalent thereof if—

(3) Anti-avoidance rule. For purposes of determining the number of partners in the partnership under paragraph (h)(1)(ii) of this section, a person (beneficial owner) owning an interest in a partnership, grantor trust, or S corporation (flow-through entity), that owns, directly or through other flow-through entities, an interest in the partnership, is treated as a partner in the partnership only if—

(i) Substantially all of the value of the beneficial owner's interest in the flow-through entity is attributable to the flow-through entity's interest (direct or indirect) in the partnership; and

(ii) A principal purpose of the use of the tiered arrangement is to permit the partnership to satisfy the 100-partner limitation in paragraph (h)(1)(ii) of this section.

(i) [Reserved]

(j) Lack of actual trading—(1) General rule. For purposes of section 7704(b) and this section, interests in a partnership are not readily tradable on a secondary market or the substantial equivalent thereof if the sum of the percentage interests in partnership capital or profits transferred during the taxable year of the partnership (other than in transfers described in paragraph (e), (f), or (g) of this section) does not exceed 2 percent of the total interests in partnership capital or profits.

(2) Examples. The following examples illustrate the rules of this paragraph (j):

(k) Percentage interests in partnership capital or profits—(1) Interests considered—(i) General rule. Except as otherwise provided in this paragraph (k), for purposes of this section, the total interests in partnership capital or profits are determined by reference to all outstanding interests in the partnership.

(ii) Exceptions—(A) General partner with greater than 10 percent interest. If the general partners and any person related to the general partners (within the meaning of section 267(b) or 707(b)(1)) own, in the aggregate, more than 10 percent of the outstanding interests in partnership capital or profits at any one time during the taxable year of the partnership, the total interests in partnership capital or profits are determined without reference to the interests owned by such persons.

(B) Derivative interests. Any partnership interests described in paragraph (a)(2)(i)(B) of this section are taken into account for purposes of determining the total interests in partnership capital or profits only if and to the extent that the partnership satisfies paragraph (d) (1) or (2) of this section.

(2) Monthly determination. For purposes of this section, except in the case of block transfers (as defined in paragraph (e)(2) of this section), the percentage interests in partnership capital or profits represented by partnership interests that are transferred during a taxable year of the partnership is equal to the sum of the percentage interests transferred for each calendar month during the taxable year of the partnership in which a transfer of a partnership interest occurs (other than a private transfer as described in paragraph (e) of this section). The percentage interests in capital or profits of interests transferred during a calendar month is determined by reference to the partnership interests outstanding during that month.

(3) Monthly conventions. For purposes of paragraph (k)(2) of this section, a partnership may use any reasonable convention in determining the interests outstanding for a month, provided the convention is consistently used by the partnership from month to month during a taxable year and from year to year. Reasonable conventions include, but are not limited to, a determination by reference to the interests outstanding at the beginning of the month, on the 15th day of the month, or at the end of the month.

(4) Block transfers. For purposes of paragraph (e)(2) of this section (defining block transfers), the partnership must determine the percentage interests in capital or profits for each transfer of an interest during the 30 calendar day period by reference to the partnership interests outstanding immediately prior to such transfer.

(5) Example. The following example illustrates the rules of this paragraph (k):

(l) Effective date—(1) In general. Except as provided in paragraph (l)(2) of this section, this section applies to taxable years of a partnership beginning after December 31, 1995.

(2) Transition period. For partnerships that were actively engaged in an activity before December 4, 1995, this section applies to taxable years beginning after December 31, 2005, unless the partnership adds a substantial new line of business after December 4, 1995, in which case this section applies to taxable years beginning on or after the addition of the new line of business. Partnerships that qualify for this transition period may continue to rely on the provisions of Notice 88-75 (1988-2 C.B. 386) (see § 601.601(d)(2) of this chapter) for guidance regarding the definition of readily tradable on a secondary market or the substantial equivalent thereof for purposes of section 7704(b).

(3) Substantial new line of business. For purposes of paragraph (l)(2) of this section—

(i) Substantial is defined in § 1.7704-2(c); and

(ii) A new line of business is defined in § 1.7704-2(d), except that the applicable date is “December 4, 1995” instead of “December 17, 1987”.

(4) Termination under section 708(b)(1)(B). The termination of a partnership under section 708(b)(1)(B) due to the sale or exchange of 50 percent or more of the total interests in partnership capital and profits is disregarded in determining whether a partnership qualifies for the transition period provided in paragraph (l)(2) of this section.
