Kroll also assigned the Houston-based company's subsidiary, Allegiance Bank, deposit and senior unsecured debt ratings of BBB+, a subordinated debt rating of BBB and short-term deposit and debt ratings of K2.

The ratings reflect Allegiance's "relatively stable overall performance" and "experienced management team." They are, however, constrained by the company's spread-reliant revenues and construction and development loan concentration. The outlook for the long-term ratings is stable.
