Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill Business combinations involving the Company’s acquisition of the equity interests or net assets of another enterprise give rise to goodwill. Total goodwill at March 31, 2021, was $53,777,000 consisting of $8,934,000, $14,643,000, $6,340,000, $10,394,000, and $13,466,000 representing the excess of the cost of Bank of Madera County, Service 1st Bancorp, Visalia Community Bank, Sierra Vista Bank, and Folsom Lake Bank, respectively, over the net of the amounts assigned to assets acquired and liabilities assumed in the transactions accounted for under the acquisition method of accounting. The value of goodwill is ultimately derived from the Company’s ability to generate net earnings after the acquisitions and is not deductible for tax purposes. A significant decline in net earnings, among other factors, could be indicative of a decline in the fair value of goodwill and result in impairment. For that reason, goodwill is assessed at least annually for impairment. The Company’s annual goodwill test is completed as of September 30 each year.Goodwill is also tested for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the Company below its carrying amount. With the economic risks and uncertainties associated with the COVID-19 pandemic continuing during the first quarter of 2021, management performed a qualitative assessment including performance trends, market information and economic data and determined it was more likely than not that the fair value of the reporting unit exceeded the carrying value. As such no quantitative goodwill impairment test was required as of March 31, 2021.
