Kroll Bond Rating Agency Assigns BBB/K3 Senior Long-Term and Short-Term Debt Ratings to United Financial Bancorp, Inc.

Kroll Bond Rating Agency (“KBRA”) has assigned a senior unsecured debt rating of BBB and short-term rating of K3 to United Financial Bancorp, Inc. (NASDAQ: UBNK) (“UBNK”), a bank holding company headquartered in Glastonbury, Connecticut. In addition, KBRA has assigned a senior deposit rating of BBB+ and short-term rating of K2 to United Bank (the “Bank”). Moreover, UBNK has been issued a subordinated debt rating of BBB-. The outlook on all ratings is stable.

The ratings are supported by UBNK’s sound capital structure, strong asset quality, and comprehensive risk management. The ratings are also balanced by concerns surrounding UBNK’s concentrated portfolio of commercial and real estate loans and the related exposure as well as integration risks following the recent merger.

The ratings are based on KBRA’s Global Bank and Bank Holding Company Rating Methodology, published on May 2, 2013.
