(a) Initial margin.
(1) Except as provided in paragraph (c) of this section, a covered swap entity shall not be required to collect initial margin from a margin affiliate provided that the covered swap entity meets the following conditions:
(i) A covered swap entity shall post initial margin to any margin affiliate that is a swap entity subject to the rules of a Prudential Regulator in an amount equal to the amount that the swap entity is required to collect from the covered swap entity pursuant to the rules of the Prudential Regulator.
(b) Variation margin. Each covered swap entity shall post and collect variation margin with each margin affiliate that is a swap entity or a financial end user in accordance with all applicable provisions of §§ 23.150 through 23.161.
(c) Foreign margin affiliates.
(2) Except as provided in paragraph (c)(3) of this section, each covered swap entity shall collect initial margin in accordance with all applicable provisions of §§ 23.150 through 23.161 from each margin affiliate that meets the following criteria:
(ii) The margin affiliate enters into swaps with third parties, or enters into swaps with any other margin affiliate that, directly or indirectly (including through a series of transactions), enters into swaps with third parties, for which the provisions of §§ 23.150 through 23.161 would apply if any such margin affiliate were a swap entity; and
(iii) Any such outward facing margin affiliate is located in a jurisdiction that the Commission has not found to be eligible for substituted compliance with regard to the provisions of §§ 23.150 through 23.161 and does not collect initial margin for such swaps in a manner that would comply with the provisions of §§ 23.150 through 23.161.
