Michael H. Lee, President and Chief Executive Officer of Tower Group, Inc. commented, "Our operating results during the fourth quarter and full year 2006 continue to be driven by the strength of our business model which produced a return on equity in excess of 20%. In addition, we are pleased that despite competitive pricing in certain market segments, we successfully executed on our marketing and underwriting strategies to achieve strong top line premium growth and excellent underwriting results. With the establishment of our strategic relationship with CastlePoint, the recently completed capital raise for Tower and the pending acquisition of Preserver, we are well positioned in 2007 to continue profitable premium growth while maintaining our underwriting and expense discipline."

For 2006, the return was calculated by dividing net income available to common stockholders of $36.6 million by an average common stockholders' equity of $164.6 million. For 2005, the return was calculated by dividing net income of $20.8 million by an average common stockholders' equity of $137.1 million. The effective income tax rate was 34.9% in 2006 compared to 34.8% in 2005. Dividend Declaration Tower Group, Inc. announced today that the Company's Board of Directors approved a quarterly dividend on February 22, 2007 of $0.025 per share payable March 30, 2007 to stockholders of record as of March 15, 2007. Additional Highlights On January 25, 2007, the Company participated in a private placement of $20.0 million of fixed/floating rate capital securities issued by Tower Group Statutory Trust VI. Interest distributions are initially at a fixed rate of 8.155% for the first five years and will then reset quarterly for changes in the three-month London Interbank Offered Rate ("LIBOR") plus 300 basis points. The net proceeds were used to redeem $20.0 million of the Preferred Stock on January 26, 2007. On January 26, 2007, the Company closed on its public offering of 2,704,000 shares of common stock at a public offering price of $31.25 per share. The Company's net proceeds were approximately $79.3 million. The Company used $20.0 million of these net proceeds to redeem its remaining $20.0 million of Preferred Stock. On February 5, 2007 the underwriters in the Company's common stock offering, partially exercised their overallotment option to acquire 340,600 shares of common stock. The exercise of the over-allotment option brings the Company's aggregate net proceeds from the offering to approximately $89.4 million. 2007 Guidance For the first quarter of 2007, we project net income to increase from the first quarter of 2006 to a range between $9.9 million and $10.8 million. We project the diluted earnings per share in the first quarter to be in the range between $0.44 and $0.48 per diluted share. We have historically experienced seasonality between the fourth and first quarters with either lower or flat growth despite overall growth for the year. For the full year, we anticipate net income to increase to a range between $55 million and $57 million and diluted earnings per share to be between $2.40 and $2.50 per diluted share.
