Kroll Bond Rating Agency Assigns BBB/K3 Senior Long-Term and Short-Term Debt Ratings to Independent Bank Group, Inc.

Kroll Bond Rating Agency (“KBRA”) has assigned a senior unsecured long-term rating of BBB, a subordinated rating of BBB-, and a short-term debt rating of K3 to Independent Bank Group, Inc. (NASDAQ:IBTX), a bank holding company headquartered in McKinney, Texas. In addition, KBRA has assigned a senior deposit rating of BBB+ and a short-term rating of K2 to the subsidiary bank, Independent Bank (the “Bank”). The outlook on all ratings is stable.

The ratings are supported by IBTX’s solid credit quality, strong earnings track record, strong risk management, and adequate capital and liquidity levels. These factors are counterbalanced by IBTX’s rapid rate of growth and high concentrations in real estate loans, which make IBTX more susceptible to credit losses in the event of a real estate downturn.

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