(a) In the event that a security-based swap dealer or major security-based swap participant succeeds to and continues the business of a security-based swap dealer or major security-based swap participant registered pursuant to Section 15F(b) of the Securities Exchange Act of 1934 (15 U.S.C. 78o-10(b)), the registration of the predecessor shall be deemed to remain effective as the registration of the successor if the successor, within 30 days after such succession, files an application for registration in accordance with § 240.15Fb2-1, and the predecessor files a notice of withdrawal from registration on Form SBSE-W (§ 249.1601 of this chapter).

(b) Notwithstanding paragraph (a) of this section, if a security-based swap dealer or major security-based swap participant succeeds to and continues the business of a registered predecessor security-based swap dealer or major security-based swap participant, and the succession is based solely on a change in the predecessor's date or state of incorporation, form of organization, or composition of a partnership, the successor may, within 30 days after the succession, amend the registration of the predecessor security-based swap dealer or major security-based swap participant on Form SBSE (§ 249.1600 of this chapter), Form SBSE-A (§ 249.1600a of this chapter), or Form SBSE-BD (§ 249.1600b of this chapter), as appropriate, to reflect these changes. This amendment shall be deemed an application for registration filed by the predecessor and adopted by the successor.
