The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.

Loans are charged off against the allowance when management believes the recorded loan balance is confirmed as uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Regardless of the determination that a charge-off is appropriate for financial accounting purposes, the Company manages its loan portfolio by continually monitoring, where possible, a borrower's ability to pay through the collection of financial information, delinquency status, borrower discussion and the encouragement to repay in accordance with the original contract or modified terms, if appropriate.</span></div><div style="margin-top:6pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">Management estimates the allowance balance using relevant information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist. Historical credit loss experience provides the basis for the estimation of expected credit losses, which captures loan balances as of a point in time to form a cohort, then tracks the respective losses generated by that cohort of loans over the remaining life. The Company identified and accumulated loan cohort historical loss data beginning with the fourth quarter of 2008 and through the current period. In situations where the Company's actual loss history was not statistically relevant, the loss history of peers, defined as financial institutions with assets greater than three billion and less than ten billion, were utilized to create a minimum loss rate. Adjustments to historical loss information are made for differences in relevant current loan-specific risk characteristics, such as historical timing of losses relative to the loan origination. In its loss forecasting framework, the Company incorporates forward-looking information through the use of macroeconomic scenarios applied over the forecasted life of the assets. These macroeconomic scenarios incorporate variables that have historically been key drivers of increases and decreases in credit losses. These variables include, but are not limited to changes in environmental conditions, such as California unemployment rates, household debt levels and U.S. gross domestic product.</span></div><div style="margin-top:6pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">A loan is considered to be collateral dependent when repayment is expected to be provided substantially through the operation or sale of the collateral. The ACL on collateral dependent loans is measured using the fair value of the underlying collateral, adjusted for costs to sell when applicable, less the amortized cost basis of the financial asset. If the value of underlying collateral is determined to be less than the recorded amount of the loan, a charge-off will be taken. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, is considered to be a TDR. The ACL on a TDR is measured using the same method as all other portfolio loans, except when the value of a concession cannot be measured using a method other than the discounted cash flow method. When the value of a concession is measured using the discounted cash flow method, the ACL is determined by discounting the expected future cash flows at the original interest rate of the loan. </span></div><div style="margin-top:6pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">PCD assets are assets acquired at a discount that is due, in part, to credit quality deterioration since origination. PCD assets are accounted for in accordance with ASC 326-20 and are initially recorded at fair value, by taking the sum of the present value of expected future cash flows and an allowance for credit losses, at acquisition. The allowance for credit losses for PCD assets is recorded through a gross-up of reserves on the balance sheet, while the allowance for acquired non-PCD assets, such as loans, is recorded through the provision for credit losses on the income statement, consistent with originated loans. Subsequent to acquisition, the allowance for credit losses for PCD loans will generally follow the same forward-looking estimation, provision, and charge-off process as non-PCD acquired and originated loans. </span></div><div style="margin-top:6pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">The Company has identified the following portfolio segments to evaluate and measure the allowance for credit loss:</span></div><div style="margin-top:6pt;padding-left:18pt;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;text-decoration:underline">Commercial real estate</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">:</span></div><div style="margin-top:6pt;padding-left:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">Commercial real estate - Non-owner occupied: These commercial properties typically consist of buildings which are leased to others for their use and rely on rents as the primary source of repayment. Property types are predominantly office, retail, or light industrial but the portfolio also has some special use properties. As such, the risk of loss associated with these properties is primarily driven by general economic changes or changes in regional economies and the impact of such on a tenant’s ability to pay. Ultimately this can affect occupancy, rental rates, or both. Additional risk of loss can come from new construction resulting in oversupply, the costs to hold or operate the property, or changes in interest rates.

This may be driven by changes in, among other things, industry challenges, factors unique to the operating geography of the borrower, change in the individual fortunes of the business owner, general economic conditions and changes in business cycles. When default is driven by issues related specifically to the business owner, collateral values tend to provide better repayment support and may result in little or no loss. Alternatively, when default is driven more by general economic conditions, the underlying collateral may have devalued more and thus result in larger losses in the event of default.

Multifamily properties are also subject to changes in general or regional economic conditions, such as unemployment, ultimately resulting in increased vacancy rates or reduced rents or both. In addition, new construction can create an oversupply condition and market competition resulting in increased vacancy, reduced market rents, or both. Due to the nature of their use and the greater likelihood of tenant turnover, the management of these properties is more intensive and therefore is more critical to the preclusion of loss.</span></div><div style="margin-top:6pt;padding-left:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">Farmland: While the Company has few loans that were originated for the purpose of the acquisition of these commercial properties, loans secured by farmland represent unique risks that are associated with the operation of an agricultural businesses. The valuation of farmland can vary greatly over time based on the property's access to resources including but not limited to water, crop prices, foreign exchange rates, government regulation or restrictions, and the nature of ongoing capital investment needed to maintain the quality of the property. Loans secured by farmland typically represent less risk to the Company than other agriculture loans as the real estate typically provides greater support in the event of default or need for longer term repayment. </span></div><div style="margin-top:6pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;text-decoration:underline">Consumer loans</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">:</span></div><div style="margin-top:6pt;padding-left:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">SFR 1-4 1st DT Liens: The most significant drivers of potential loss within the Company's residential real estate portfolio relate general, regional, or individual changes in economic conditions and their effect on employment and borrowers cash flow. Risk in this portfolio is best measured by changes in borrower credit score and loan-to-value. Loss estimates are based on the general movement in credit score, economic outlook and its effects on employment and the value of homes and the Bank’s historical loss experience adjusted to reflect the economic outlook and the unemployment rate.</span></div><div style="margin-top:6pt;padding-left:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">SFR HELOCs and Junior Liens: Similar to residential real estate term loans, HELOCs and junior liens performance is also primarily driven by borrower cash flows based on employment status. However, HELOCs carry additional risks associated with the fact that most of these loans are secured by a deed of trust in a position that is junior to the primary lien holder. Furthermore, the risk that as the borrower's financial strength deteriorates, the outstanding balance on these credit lines may increase as they may only be canceled by the Company if certain limited criteria are met. In addition to the allowance for credit losses maintained as a percent of the outstanding loan balance, the Company maintains additional reserves for the unfunded portion of the HELOC. </span></div><div style="margin-top:6pt;padding-left:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">Other: The majority of consumer loans are secured by automobiles, with the remainder primarily unsecured revolving debt (credit cards). These loans are susceptible to three primary risks; non-payment due to income loss, over-extension of credit and, when the borrower is unable to pay, shortfall in collateral value, if any. Typically non-payment is due to loss of job and will follow general economic trends in the marketplace driven primarily by rises in the unemployment rate. Loss of collateral value can be due to market demand shifts, damage to collateral itself or a combination of those factors. Credit card loans are unsecured and while collection efforts are pursued in the event of default, there is typically limited opportunity for recovery. Loss estimates are based on the general movement in credit score, economic outlook and its effects on employment and the Bank’s historical loss experience adjusted to reflect the economic outlook and the unemployment rate.</span></div><div style="margin-top:6pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;text-decoration:underline">Commercial and Industrial:</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"> </span></div><div style="margin-top:6pt;padding-left:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">Repayment of these loans is primarily based on the cash flow of the borrower, and secondarily on the underlying collateral provided by the borrower. A borrower's cash flow may be unpredictable, and collateral securing these loans may fluctuate in value. Most often, collateral includes accounts receivable, inventory, or equipment. Collateral securing these loans may depreciate over time, may be difficult to appraise, may be illiquid and may fluctuate in value based on the success of the business. Actual and forecast changes in gross domestic product are believed to be corollary to losses associated with these credits.</span></div><div style="margin-top:6pt;padding-left:18pt;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;text-decoration:underline">Construction</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">: </span></div><div style="margin-top:6pt;padding-left:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">While secured by real estate, construction loans represent a greater level of risk than term real estate loans due to the nature of the additional risks associated with the not only the completion of construction within an estimated time period and budget, but also the need to either sell the building or reach a level of stabilized occupancy sufficient to generate the cash flows necessary to support debt </span></div><div style="margin-top:6pt;padding-left:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">service and operating costs.

These factors include adverse weather conditions, including access to water, that may impact crop yields, loss of livestock due to disease or other factors, declines in market prices for agriculture products, changes in foreign exchange, and the impact of government regulations. In addition, many farms are dependent on a limited number of key individuals whose injury or death may significantly affect the successful operation of the business. Consequently, agricultural production loans may involve a greater degree of risk than other types of loans.</span></div><div style="margin-top:6pt;padding-left:18pt;text-indent:-18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;text-decoration:underline">Leases:</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"> </span></div><div style="margin-top:6pt;padding-left:18pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">The loss forecasting model applies the historical rate of loss for similar loans over the expected life of the asset. Leases typically represent an elevated level of credit risk as compared to loans secured by real estate as the collateral for leases is often subject to a more rapid rate of depreciation or depletion.
