("Munich") commenced an action against Tower Insurance Company of New York (“TICNY”), a wholly-owned subsidiary of Tower Group, Inc., in the United States District Court for the District of New Jersey seeking, among other things, to recover $6.1 million under various retrocessional contracts pursuant to which TICNY reinsures Munich. On June 22, 2009, TICNY filed its answer, in which it, inter alia, asserted two separate counterclaims seeking to recover $2.8 million under various reinsurance contracts pursuant to which Munich reinsures TICNY. A separate action commenced by Munich against TICNY on June 17, 2009 in the United States District Court for the District of New Jersey seeking a declaratory judgment that Munich is entitled to access TICNY's books and records pertaining to various quota share agreements, to which TICNY filed its answer on July 7, 2009, was subsequently dismissed pursuant to the stipulation of the parties on March 17, 2010. The parties are currently engaged in discovery and the Company is therefore unable to assess the likelihood of any particular outcome.  On May 12, 2010, Mirabilis Ventures, Inc. (“Mirabilis”) commenced an action against Specialty Underwriters' Alliance Insurance Co. (“SUA”, now known as CastlePoint National Insurance Company (“CNIC”), a subsidiary of Tower Group, Inc.) and Universal Reinsurance Co., Ltd., an unrelated entity, in the United States District Court for the Middle District of Florida. The Complaint is based upon a Workers' Compensation/Employer's Liability policy issued by SUA to AEM, Inc. (“AEM”), to whose legal rights Mirabilis is alleged to have succeeded as a result of the Chapter 11 bankruptcy of AEM. The Complaint, which includes claims against SUA for breach of contract and breach of the duty of good faith, alleges that SUA failed to properly audit AEM's operations to determine AEM's Workers' Compensation exposure for two policy years, in order to compute the premium owed by AEM, such that SUA owes Mirabilis the principal sum of $3.4 million for one policy year and $0.6 million for the other policy year, plus interest and costs. On July 30, 2010, CNIC answered the complaint and asserted nine separate counterclaims, to which Mirabilis responded on September 3, 2010. Since that time, Mirabilis has filed an amended complaint that failed to add any new claims against CNIC, and CNIC has filed amended counterclaims and affirmative defenses against Mirabilis. The litigation is only in its preliminary stage, and the Company is therefore unable to assess the likelihood of any particular outcome.Note 13—ContingenciesLegal ProceedingsOn May 28, 2009, Munich Reinsurance America, Inc.
