The concentration of loans originated in this area may subject the Company to the risk of adverse impacts of economic, regulatory or other developments that could occur in Southern California. The Company has significant concentration in commercial real estate loans. The Company obtains what it believes to be sufficient collateral to secure potential losses. The extent and value of the collateral obtained varies based upon the details underlying each loan agreement.</span>

Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that in management’s judgment should be charged off.</span></div><div style="margin-top:12pt;text-align:justify;text-indent:36pt"><span style="background-color:#ffffff;color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. A loan is impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement.</span></div><div style="margin-top:12pt;text-align:justify;text-indent:36pt"><span style="background-color:#ffffff;color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings and classified as impaired. Troubled debt restructurings are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses.</span></div><div style="margin-top:12pt;text-align:justify;text-indent:36pt"><span style="background-color:#ffffff;color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial real estate and construction loans. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Income recognition on impaired loans materially conforms to the method the Company uses for income recognition on nonaccrual loans.</span></div><div style="margin-top:12pt;text-align:justify;text-indent:36pt"><span style="background-color:#ffffff;color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Allowance for impaired loans is determined based on the present value of the estimated cash flows or on the fair value of the collateral if the loan is collateral dependent, less costs to sell. If the measured fair value is less than the recorded investment in the loan, the deficiency will be charged off against the allowance for loan losses, or alternatively, a specific allocation will be established. For consumer loans, management will generally charge off the balance if the loan is 90 days or more past due.</span></div><div style="margin-top:12pt;text-align:justify;text-indent:36pt"><span style="background-color:#ffffff;color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The general component of the allowance covers non-impaired loans and is based on historical loss experience adjusted for current factors. The historical loss experience is determined by portfolio segment and is based on the actual loss history experienced by the Company over the most recent two years. For those portfolio segments that the Company does not have sufficient historical data available to track the loss migration, the loss factors are based on the actual loss history experienced by the Company over the most recent five years. This actual loss experience is supplemented with other economic factors based on the risks present for each portfolio segment. These economic factors include consideration of the following: levels of and trends in delinquencies and impaired loans; levels of and trends in charge-offs and </span></div><div style="margin-top:12pt;text-align:justify"><span style="background-color:#ffffff;color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards; other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations.</span></div><div style="margin-top:12pt;text-align:justify;text-indent:36pt"><span style="background-color:#ffffff;color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The following portfolio segments have been identified in the Company’s loan portfolio, and are also representative of the classes within the portfolio: commercial real estate, SBA loans—real estate, SBA loans—non-real estate, commercial and industrial, home mortgage, and consumer. The Company reviews the credit risk exposure of all its portfolio segments by internally assigned grades. The Company categorizes loans into risk grades based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. For the home mortgage and consumer portfolio segments, the Company’s primary monitoring tool is reviewing past due listings to determine if the loans are performing.</span></div><div style="margin-top:12pt;text-align:justify;text-indent:36pt"><span style="background-color:#ffffff;color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The determination of the allowance for loan losses is based on estimates that are particularly susceptible to changes in the economic environment and market conditions.</span></div>
