DEREGISTRATION OF SECURITIES

On November 9, 2004, Tower Group, Inc. (the “Predecessor Registrant”), the predecessor to Tower Group International, Ltd. (the “Registrant”), filed Registration Statement No. 333-120320 on Form S-8 (the “2004 Registration Statement”) pursuant to which the Predecessor Registrant registered the offering of 354,600 shares of common stock, par value $0.01 per share (the “Common Stock”) under the Tower Group, Inc. 2001 Stock Award Plan (the “2001 Plan”) and 1,093,891 shares of Common Stock under the Tower Group, Inc. 2004 Long Term Equity Compensation Plan (the “2004 Plan”).

On March 25, 2013, the Registrant filed Post Effective Amendment No. 1 to the 2004 Registration Statement as successor to the Predecessor Registrant pursuant to Rule 414 under the Securities Act of 1933, as amended, with respect to the 2004 Plan.

On September 24, 2014, the Registrant filed Post Effective Amendment No. 2 to the 2004 Registration Statement to remove from registration any unsold shares of Common Stock under the 2004 Plan.

On September 15, 2014, pursuant to the Agreement and Plan of Merger dated as of January 3, 2014, among ACP Re, Ltd., a Bermuda exempted company (“Parent”), London Acquisition Company Limited, a Bermuda exempted company and wholly owned subsidiary of ACP Re (“Merger Sub”), and the Registrant, Merger Sub merged with and into the Registrant, with the Registrant continuing as the surviving corporation and a wholly owned subsidiary of Parent (the “Merger”). As a result of the Merger, the Registrant has terminated all offerings of Common Stock pursuant to its existing registration statements, including the 2004 Registration Statement. Shares of Common Stock will no longer be offered or sold under the 2001 Plan. In accordance with an undertaking made by the Registrant in the 2004 Registration Statement to remove from registration, by means of a post-effective amendment, any shares of Common Stock that remain unsold at the termination of the relevant offering, the Registrant hereby removes from registration all shares of its Common Stock previously authorized under the 2004 Registration Statement to be offered or sold by the Registrant under the 2001 Plan and that remained unsold as of the effective time of the Merger.

This Post-Effective Amendment No. 3 is being filed in accordance with the requirements of Item 512(a)(3) of Regulation S-K.
