These estimates, assumptions, and judgments are based on information available as of the date of the financial statements; accordingly, as this information changes, the financial statements could reflect different estimates, assumptions, and judgments. Certain accounting policies inherently have a greater reliance on the use of estimates, assumptions and judgments and as such have a greater possibility of producing results that could be materially different than originally reported. Estimates, assumptions and judgments are necessary when assets and liabilities are required to be recorded at fair value, when a decline in the value of an asset not third Debt Securities. Debt securities consist of the U.S. Treasury, securities of government sponsored entities, states, counties, municipalities, corporations, agency and non-agency mortgage-backed securities, collateralized loan obligations and commercial paper.

That is, for pools of such securities with common risk characteristics, the historical lifetime probability of default and severity of loss in the event of default is derived or obtained from external sources and adjusted for the expected effects of reasonable and supportable forecasts over the expected lives of the securities on those historical credit losses.

Interest and dividend income are recognized when earned. Realized gains and losses from the sale of available for sale debt securities are included in earnings using the specific identification method. Nonmarketable Equity Securities. Nonmarketable equity securities include securities that are not Loans. Loans are stated at the principal amount outstanding, net of unearned discount and unamortized deferred fees and costs.

Allowance for Credit Losses. The Company extends loans to commercial and consumer customers primarily in Northern and Central California. These lending activities expose the Company to the risk borrowers will default, causing loan losses. The Company’s lending activities are exposed to various qualitative risks. All loan segments are exposed to risks inherent in the economy and market conditions. Significant risk characteristics related to the commercial loan segment include the borrowers’ business performance and financial condition, and the value of collateral for secured loans. Significant risk characteristics related to the commercial real estate segment include the borrowers’ business performance and the value of properties collateralizing the loans. Significant risk characteristics related to the construction loan segment include the borrowers’ performance in successfully developing the real estate into the intended purpose and the value of the property collateralizing the loans. Significant risk characteristics related to the residential real estate segment include the borrowers’ financial wherewithal to service the mortgages and the value of the property collateralizing the loans. Significant risk characteristics related to the consumer loan segment include the financial condition of the borrowers and the value of collateral securing the loans. The preparation of these financial statements requires Management to estimate the amount of expected losses over the expected contractual life of the Bank’s existing loan portfolio and establish an allowance for credit losses. Loan agreements generally include a maturity date, and the Company considers the contractual life of a loan agreement to extend from the date of origination to the contractual maturity date. In estimating credit losses, Management must exercise significant judgment in evaluating information deemed relevant. The amount of ultimate losses on the loan portfolio can vary from the estimated amounts. Management follows a systematic methodology to estimate loss potential in an effort to reduce the differences between estimated and actual losses. The allowance for credit losses is established through provisions for credit losses charged to income. Losses on loans are charged to the allowance for credit losses when all or a portion of the recorded amount of a loan is deemed to be uncollectible. Recoveries of loans previously charged off are credited to the allowance when realized. The Company’s allowance for credit losses is maintained at a level considered adequate to provide for expected losses based on historical loss rates adjusted for current and expected conditions over a forecast period. These include conditions unique to individual borrowers, as well as overall credit loss experience, the amount of past due, nonperforming and classified loans, recommendations of regulatory authorities, prevailing economic conditions, or credit protection agreements and other factors. Loans that share common risk characteristics are segregated into pools based on common characteristics, which is primarily determined by loan, borrower, or collateral type. Historical loss rates are determined for each pool. For consumer installment loans, primarily secured by automobiles, historical loss rates are determined using a vintage methodology, which tracks losses based on period of origination. For commercial, construction, and commercial real estate, historical loss rates are determined using an open pool methodology where losses are tracked over time for all loans included in the pool at the historical measurement date. Historical loss rates are adjusted for factors that are not not two not not two Loans that do not not Accrued interest is recorded in other assets and is excluded from the estimation of expected credit loss. Accrued interest is reversed through interest income when amounts are determined to be uncollectible, which generally occurs when the underlying receivable is placed on nonaccrual status or charged off. Liability for Off-Balance Sheet Credit Exposures. Off-balance sheet credit exposures relate to letters of credit and unfunded loan commitments for commercial, construction and consumer loans. The Company maintains a separate allowance for credit losses from off-balance-sheet credit exposures, which is included within other liabilities on the consolidated statements of financial condition. Increases or reductions to the Company’s allowance for credit losses from off-balance sheet credit exposures are recorded in other expenses.

Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for Credit Losses. The Company extends loans to commercial and consumer customers primarily in Northern and Central California. These lending activities expose the Company to the risk borrowers will default, causing loan losses. The Company’s lending activities are exposed to various qualitative risks. All loan segments are exposed to risks inherent in the economy and market conditions. Significant risk characteristics related to the commercial loan segment include the borrowers’ business performance and financial condition, and the value of collateral for secured loans. Significant risk characteristics related to the commercial real estate segment include the borrowers’ business performance and the value of properties collateralizing the loans. Significant risk characteristics related to the construction loan segment include the borrowers’ performance in successfully developing the real estate into the intended purpose and the value of the property collateralizing the loans. Significant risk characteristics related to the residential real estate segment include the borrowers’ financial wherewithal to service the mortgages and the value of the property collateralizing the loans. Significant risk characteristics related to the consumer loan segment include the financial condition of the borrowers and the value of collateral securing the loans. The preparation of these financial statements requires Management to estimate the amount of expected losses over the expected contractual life of the Bank’s existing loan portfolio and establish an allowance for credit losses. Loan agreements generally include a maturity date, and the Company considers the contractual life of a loan agreement to extend from the date of origination to the contractual maturity date. In estimating credit losses, Management must exercise significant judgment in evaluating information deemed relevant. The amount of ultimate losses on the loan portfolio can vary from the estimated amounts. Management follows a systematic methodology to estimate loss potential in an effort to reduce the differences between estimated and actual losses. The allowance for credit losses is established through provisions for credit losses charged to income. Losses on loans are charged to the allowance for credit losses when all or a portion of the recorded amount of a loan is deemed to be uncollectible. Recoveries of loans previously charged off are credited to the allowance when realized. The Company’s allowance for credit losses is maintained at a level considered adequate to provide for expected losses based on historical loss rates adjusted for current and expected conditions over a forecast period.
