The company's liabilities include $36.0 million in debt obligations due to its trust subsidiaries, related to TruPS issued by those entities. Bank of the Sierra, a California state-chartered bank headquartered in Porterville, California, offers a wide range of retail and commercial banking services. The Bank was incorporated in September 1977 and opened for business in January 1978. Its growth has largely been organic, supplemented by four whole-bank acquisitions: Sierra National Bank in 2000, Santa Clara Valley Bank in 2014, Coast National Bank in 2016, and Ojai Community Bank in 2017. The Bank maintains administrative offices, loan production offices, and 34 full-service branches located throughout California's South San Joaquin Valley, the Central Coast, Ventura County, and neighboring communities.
