A.M. Best Co. has affirmed the financial strength rating of A (Excellent) and issuer credit ratings (ICR) of “a” of The Hanover Insurance Group Property and Casualty Companies (The Hanover) and its members. Additionally, A.M. Best has affirmed the ICR of “bbb” and all existing debt ratings of the parent holding company, The Hanover Insurance Group, Inc. (THG) [NYSE: THG]. The outlook for all ratings is stable. Both companies are domiciled in Worcester, MA. (Please see below for a detailed listing of the companies and ratings.)

The ratings reflect The Hanover’s excellent risk-adjusted capitalization, stemming from consistently favorable operating earnings. Despite consistent dividend payments to THG in recent years, The Hanover has been able to increase surplus over the past five years through solid net investment income, and to a lesser degree, generally favorable underwriting performance. In addition, the ratings reflect the company’s prudent risk management and diversified product offerings, especially in the commercial and specialty segments of its book of business. The ratings also recognize moderate financial leverage and the financial flexibility at THG.

Partially offsetting these positive rating factors is The Hanover’s comparatively high underwriting leverage and somewhat elevated expense structure.

Previously, A.M. Best commented that both The Hanover and THG’s ratings were unchanged following the announcement in April 2011 that THG was proposing to acquire Chaucer Holdings PLC (Chaucer) (United Kingdom) [LSE: CHU], a leading specialist insurance group and the parent of Lloyd’s Syndicates 1084 and 1176. The transaction, which is subject to the approval of regulatory bodies in the United States and United Kingdom, is expected to close during the third quarter of 2011. (Please see the A.M. Best press release dated April 20, 2011 for further details.)
