Concentration Risk, Credit Risk, Policy [Policy Text Block]

Concentrations. The Bank was incorporated in California and started its business from California. Therefore, loans originated and deposits solicited were mainly from California. As of December 31, 2015, gross loans were primarily comprised of 52.2% of commercial mortgage loans and 22.8% of commercial loans. As of December 31, 2015, approximately 61% of the Bank’s residential mortgages were for properties located in California. Approximately 71% of the Company’s CDs of $250,000 or more have been on deposit with the Company for two years or more.

Marketable Securities, Held-to-maturity Securities, Policy [Policy Text Block]

Securities. Securities are classified as held-to-maturity when management has the ability and intent to hold these securities until maturity. Securities are classified as available-for-sale when management intends to hold the securities for an indefinite period of time, or when the securities may be utilized for tactical asset/liability purposes, and may be sold from time to time to manage interest rate exposure and resultant prepayment risk and liquidity needs. Securities are classified as trading securities when management intends to sell the securities in the near term. Securities purchased are designated as held-to-maturity, available-for-sale, or trading securities at the time of acquisition.

Securities held-to-maturity are stated at cost, adjusted for the amortization of premiums and the accretion of discounts on a level-yield basis. The carrying value of these assets is not adjusted for temporary declines in fair value since the Company has the positive intent and ability to hold them to maturity. Securities available-for-sale are carried at fair value, and any unrealized holding gains or losses are excluded from earnings and reported as a separate component of stockholders’ equity, net of tax, in accumulated other comprehensive income until realized. Realized gains or losses are determined on the specific identification method. Premiums and discounts are amortized or accreted as adjustment of yield on a level-yield basis.

ASC Topic 320 requires an entity to assess whether the entity has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. If either of these conditions is met, an entity must recognize an other-than-temporary impairment (“OTTI”). If an entity does not intend to sell the debt security and will not be required to sell the debt security, the entity must consider whether it will recover the amortized cost basis of the security. If the present value of expected cash flows is less than the amortized cost basis of the security, OTTI shall be considered to have occurred. OTTI is then separated into the amount of the total impairment related to credit losses and the amount of the total impairment related to all other factors. An entity determines the impairment related to credit losses by comparing the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. OTTI related to the credit loss is then recognized in earnings. OTTI related to all other factors is recognized in other comprehensive income. OTTI not related to the credit loss for a held-to-maturity security should be recognized separately in a new category of other comprehensive income and amortized over the remaining life of the debt security as an increase in the carrying value of the security only when the entity does not intend to sell the security and it is not more likely than not that the entity will be required to sell the security before recovery of its remaining amortized cost basis. The Company has both the ability and the intent to hold and it is not more likely than not that the Company will be required to sell those securities with unrealized losses before recovery of their amortized cost basis.

Trading securities are reported at fair value, with unrealized gains or losses included in income.

Finance, Loans and Leases Receivable, Policy [Policy Text Block]

Loans. Loans are carried at amounts advanced, less principal payments collected and net deferred loan fees. Interest is accrued and earned daily on an actual or 360-day basis. Interest accruals on business loans and non-residential real estate loans are generally discontinued whenever the payment of interest or principal is 90 days or more past due, based on contractual terms. Such loans are placed on non-accrual status, unless the loan is well secured, and there is a high probability of recovery in full, as determined by management. When loans are placed on non-accrual status, previously accrued but unpaid interest is reversed and charged against current income, and subsequent payments received are generally first applied toward the outstanding principal balance of the loan. The loan is generally returned to accrual status when the borrower has brought the past due principal and interest payments current and, in the opinion of management, the borrower has demonstrated the ability to make future payments of principal and interest as scheduled. A non-accrual loan may also be returned to accrual status if all principal and interest contractually due are reasonably assured of repayment within a reasonable period and there has been a sustained period of payment performance, generally six months. Loan origination fees and commitment fees, offset by certain direct loan origination costs, are deferred and recognized over the contractual life of the loan as a yield adjustment. The amortization utilizes the interest method. If a loan is placed on non-accrual status, the amortization of the loan fees and the accretion of discounts are discontinued until the loan is returned to accruing status.

Loans held for sale are carried at the lower of aggregate cost or fair value. Gains and losses are recorded in non-interest income based on the difference between sales proceeds, net of sales commissions, and carrying value.

Impaired Financing Receivable, Policy [Policy Text Block]

Impaired Loans. A loan is considered impaired when it is probable that the Bank will be unable to collect all amounts due (i.e. both principal and interest) according to the contractual terms of the loan agreement. The measurement of impairment may be based on (1) the present value of the expected future cash flows of the impaired loan discounted at the loan’s original effective interest rate, (2) the observable market price of the impaired loan or (3) the fair value of the collateral of a collateral-dependent loan. The amount by which the recorded investment in the loan exceeds the measure of the impaired loan is recognized by recording a valuation allowance with a corresponding charge to the provision for loan losses. The Company stratifies its loan portfolio by size and treats smaller non-performing loans with an outstanding balance based on the Company’s defined criteria, generally where the loan amount is $500,000 or less, as a homogenous portfolio. Once a loan has been identified as a possible problem loan, the Company conducts a periodic review of such loan in order to test for impairment. When loans are placed on an impaired status, previously accrued but unpaid interest is reversed against current income and subsequent payments received are generally first applied toward the outstanding principal balance of the loan.

Loan Commitments, Policy [Policy Text Block]

Unfunded Loan Commitments. Unfunded loan commitments are generally related to providing credit facilities to clients of the Bank, and are not actively traded financial instruments. These unfunded commitments are disclosed as off-balance sheet financial instruments in Note 15 in the Notes to Consolidated Financial Statements.

Property, Plant and Equipment, Policy [Policy Text Block]

Premises and Equipment. Premises and equipment are carried at cost, less accumulated depreciation. Depreciation is computed on the straight-line method based on the following estimated useful lives of the assets:

Type	Estimated Useful Life (in years)
Buildings	15	to	45
Building improvements	5	to	20
Furniture, fixtures, and equipment	3	to	25
Leasehold improvements	Shorter of useful lives or the terms of the leases

Improvements are capitalized and amortized to occupancy expense based on the above table. Construction in process is carried at cost and includes land acquisition cost, architectural fees, general contractor fees, capitalized interest and other costs related directly to the construction of a property.

Investments In Affordable Housing [Policy Text Block]

Investments in Affordable Housing Partnerships and Other Tax Credit Investments. The Company is a limited partner in limited partnerships that invest in low-income housing projects that qualify for Federal and/or State income tax credits and a limited partnership that invests in alternative energy systems. As further discussed in Note 7, the partnership interests are accounted for utilizing the equity method of accounting. As of December 31, 2015, seven of the limited partnerships in which the Company has an equity interest were determined to be variable interest entities for which the Company is the primary beneficiary. The Company therefore consolidated the financial statements of these seven limited partnerships into its Consolidated Financial Statements. The tax credits from these partnerships are recognized in the consolidated financial statements to the extent they are utilized on the Company’s income tax returns. The investments are reviewed for impairment on an annual basis or on an interim basis if an event occurs that would trigger potential impairment.

Goodwill and Intangible Assets, Policy [Policy Text Block]

Goodwill and Goodwill Impairment. Goodwill represents the excess of costs over fair value of assets of businesses acquired. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but instead are tested for impairment at least annually in accordance with the provisions of ASC Topic 350. ASC Topic 350 also requires that intangible assets with estimable useful lives be amortized over their respective estimated useful lives to their estimated residual values, and reviewed for impairment in accordance with ASC Topic 360.

The Company’s policy is to assess goodwill for impairment at the reporting unit level on an annual basis or between annual assessments if a triggering event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Impairment is the condition that exists when the carrying amount of goodwill exceeds its implied fair value. Accounting standards require management to estimate the fair value of each reporting unit in making the assessment of impairment at least annually.

The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in ASC Topic 350. The two-step impairment testing process conducted by us, if needed, begins by assigning net assets and goodwill to our reporting units. The Company then completes “step one” of the impairment test by comparing the fair value of each reporting unit (as determined based on the discussion below) with the recorded book value (or “carrying amount”) of its net assets, with goodwill included in the computation of the carrying amount. If the fair value of a reporting unit exceeds its carrying amount, goodwill of that reporting unit is not considered impaired, and “step two” of the impairment test is not necessary. If the carrying amount of a reporting unit exceeds its fair value, step two of the impairment test is performed to determine the amount of impairment. Step two of the impairment test compares the carrying amount of the reporting unit’s goodwill to the “implied fair value” of that goodwill. The implied fair value of goodwill is computed by assuming that all assets and liabilities of the reporting unit would be adjusted to the current fair value, with the offset as an adjustment to goodwill. This adjusted goodwill balance is the implied fair value used in step two. An impairment charge is recognized for the amount by which the carrying amount of goodwill exceeds its implied fair value.

The Company has identified two reporting units for its business: the Commercial Lending unit and the Retail Banking unit. The reporting unit fair values were determined based on an equal weighting of (1) a market approach using a combination of price to earnings multiples determined based on a representative peer group applied to 2015 and forecasted 2016 and 2017 earnings, and a price to book multiple and (2) a dividend discount model with the discount rate determined using the same representative peer group. A control premium was then applied to the unit fair values so determined as of December 31, 2015. As a result of this analysis, the Company determined that there was no goodwill impairment at December 31, 2015 as the fair value of all reporting units exceeded the current carrying amount of the units. No assurance can be given that goodwill will not be written down in future periods.

Repurchase Agreements, Valuation, Policy [Policy Text Block]

Securities Sold Under Agreements to Repurchase. The Company sells certain securities under agreements to repurchase. The agreements are treated as collateralized financing transactions and the obligations to repurchase securities sold are reflected as a liability in the accompanying Consolidated Balance Sheets. The securities underlying the agreements remain in the applicable asset accounts.

Derivatives, Policy [Policy Text Block]

Derivatives. The Company follows ASC Topic 815 that establishes accounting and reporting standards for financial derivatives, including certain financial derivatives embedded in other contracts, and hedging activities. It requires the recognition of all financial derivatives as assets or liabilities in the Company’s consolidated balance sheet and measurement of those financial derivatives at fair value. The accounting treatment of changes in fair value is dependent upon whether or not a financial derivative is designated as a hedge and, if so, the type of hedge. Fair value is determined using third-party models with observable market data. For derivatives designated as cash flow hedges, changes in fair value are recognized in other comprehensive income and are reclassified to earnings when the hedged transaction is reflected in earnings. For derivatives designated as fair value hedges, changes in the fair value of the derivatives are reflected in current earnings, together with changes in the fair value of the related hedged item if there is a highly effective correlation between changes in the fair value of the interest rate swaps and changes in the fair value of the underlying asset or liability that is intended to be hedged. If there is not a highly effective correlation between changes in the fair value of the interest rate swap and changes in the fair value of the underlying asset or liability that is intended to be hedged, then only the changes in the fair value of the interest rate swaps are reflected in the Company’s consolidated financial statements.

Income Tax, Policy [Policy Text Block]

Income Taxes. The provision for income taxes is based on income reported for financial statement purposes, and differs from the amount of taxes currently payable, since certain income and expense items are reported for financial statement purposes in different periods than those for tax reporting purposes. The Company accounts for income taxes using the asset and liability approach, the objective of which is to establish deferred tax assets and liabilities for the temporary differences between the financial reporting basis and the tax basis of the Company’s assets and liabilities at enacted tax rates expected to be in effect when such amounts are realized or settled. A valuation allowance is established for deferred tax assets if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

Earnings Per Share, Policy [Policy Text Block]

Net Income per Common Share. Earnings per share (“EPS”) is computed on a basic and diluted basis. Basic EPS excludes dilution and is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shares in the earnings of the Company. Potential dilution is excluded from computation of diluted per-share amounts when a net loss from operations exists.

Cash and Cash Equivalents, Policy [Policy Text Block]

Statement of Cash Flows. Cash and cash equivalents include short-term highly-liquid investments that generally have an original maturity of three months or less.

New Accounting Pronouncements, Policy [Policy Text Block]

Recent Accounting Pronouncements

In June 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period.” ASU No. 2014-12 requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. An entity should recognize compensation cost in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the periods for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. ASU 2014-12 becomes effective for interim and annual periods beginning on or after December 15, 2015. Adoption of ASU 2014-12 is not expected to have a significant impact on the Company’s consolidated financial statements.

ASU 2014-15, “Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” issued by the FASB in August 2014, requires an entity’s management to evaluate and disclose conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. In addition, an entity’s management is to disclose management’s plans that alleviated or that are intended to mitigate the conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern. ASU 2014-15 becomes effective for interim and annual periods beginning on or after December 15, 2016. Adoption of ASU 2014-15 is not expected to have a significant impact on the Company’s consolidated financial statements.

In February 2015, the FASB issued ASU 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis,” to improve targeted areas of the consolidation guidance and reduce the number of consolidation models. The Company may either apply the amendments retrospectively or use a modified retrospective approach. ASU 2015-02 is effective for interim and annual periods beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. Adoption of this guidance is not expected to have a significant effect on the Company’s consolidated financial statements.

In April 2015, the FASB issued ASU 2015-03, “Interest- Imputation of Interest (Subtopic 835-30).” This update simplifies the presentation of debt issuance costs and requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. ASU 2015-03 did not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. In August 2015, the FASB issued ASU 2015-15, which would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratable over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU 2015-03 becomes effective for interim and annual periods beginning on or after December 15, 2015. Adoption of ASU 2015-03 is not expected to have a significant impact on the Company’s consolidated financial statements.

In September 2015, the FASB issued ASU 2015-16, “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments.” This update simplifies the accounting for adjustments made to provisional amounts recognized in a business combination by eliminating the requirement to retrospectively account for those adjustments. Those adjustments will be recognized to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. An entity is required to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 becomes effective for interim and annual periods beginning on or after December 15, 2015. Adoption of ASU 2015-16 is not expected to have a significant impact on the Company’s consolidated financial statements.

In November 2015, the FASB issued ASU 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes”. This update simplifies the presentation of deferred income taxes by classifying deferred tax liabilities and assets as noncurrent in a classified statement of financial position. ASU 2015-17 becomes effective for interim and annual periods beginning on or after December 15, 2016. Adoption of ASU 2015-17 is not expected to have a significant impact on the Company’s consolidated financial statements.

In January 2016, the FASB issued ASU 2016-01, “Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” This update requires an entity to measure equity investments with readily determinable fair values at fair value with changes in fair value recognized in net income. Equity investment without readily determinable fair values will be measured at fair value either upon the occurrence of an observable price change or upon identification of an impairment and any amount by which the carrying value exceeding the fair value will be recognized as an impairment in net income. This updates requires also an entity to disclose fair value of financial instruments measured at amortized cost on the balance sheet to measure that fair value using the exit price option. In addition, this updates requires separate presentation in comprehensive income for changes in the fair value of a liability and in balance sheet by measurement category and form of financial asset. ASU 2016-01 becomes effective for interim and annual periods beginning on or after December 15, 2017. Adoption of ASU 2016-01 is not expected to have a significant impact on the Company’s consolidated financial statements.
