	Basis of Presentation: The consolidated financial statements include the accounts of the Company and all other entities in which it has a controlling financial interest. All significant intercompany accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its wholly owned subsidiaries. The accounting and reporting polices of the Company are based upon U.S. generally accepted accounting principles (GAAP) and conform to predominant practices within the financial services industry. Significant accounting policies followed by the Company are presented below.
	Certain prior period amounts have been reclassified to conform to the current year's presentation. These reclassifications had no impact on the Company's consolidated financial position, results of operations or net change in cash or cash equivalents.
	Use of Estimates in the Preparation of Financial Statements: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and disclosures provided, and actual results could differ. The allowance for loan and lease losses, reserve for loss on repurchased loans, servicing rights, realization of deferred tax assets, the valuation of goodwill and other intangible assets, mortgage banking derivatives, purchased credit impaired loan discount accretion, fair value of assets and liabilities acquired in business combinations, and the fair value measurement of financial instruments are particularly subject to change and such change could have a material effect on the consolidated financial statements.
	Cash and cash equivalents: Cash and cash equivalents include cash on hand, interest-bearing deposits with other financial institutions with original maturities under 90 days, and daily federal funds sold. Net cash flows are reported for customer loan and deposit transactions, interest bearing deposits in other financial institutions, and federal funds purchased, including overnight borrowings with the Federal Home Loan Bank.
	Cash flows from loans, either originated or acquired, are classified at that time according to management's original intent to either sell or hold the loan for the foreseeable future. When management's intent at origination or purchase is to sell the loan, the cash flows of that loan are presented as operating cash flows. When management's intent is to hold the loan for the foreseeable future, the cash flows of that loan are presented as investing cash flows.
	Time Deposits in Financial Institutions: Time deposits in financial institutions have original maturities over 90 days and are carried at cost.
	Securities: Investment securities are classified at the time of purchase as available for sale or held-to-maturity. Debt securities classified as held to maturity are recorded at amortized cost when management has the positive intent and ability to hold them to maturity. Debt securities are classified as available-for-sale when management intends that they might be sold before maturity. Equity securities with readily determinable fair values are classified as available-for-sale. Securities available-for-sale are carried at fair value with unrealized holding gains and losses, net of taxes, reported in other comprehensive income or loss.
	Accreted discounts and amortized premiums are included in interest income using the level yield method, and realized gains or losses from sales of securities are calculated using the specific identification method.
	Management evaluates securities for other-than-temporary impairment (OTTI) at least on a quarterly basis, and more frequently when economic conditions warrant such an evaluation. Investment securities classified as available for sale or held-to-maturity are generally evaluated for OTTI under Statement of Financial Accounting Standards Accounting Standards Codification (ASC) 320, Accounting for Certain Investments in Debt and Equity Securities. However, certain purchased beneficial interests, including non-agency mortgage-backed securities, asset-backed securities, and collateralized debt obligations, that had credit ratings at the time of purchase of below AA are evaluated using the model outlined in ASC 325, Recognition of Interest Income and Impairment on Purchased Beneficial Interests and Beneficial Interests that Continue to be Held by a Transfer in Securitized Financial Assets.
	In determining OTTI under the ASC 320 model, management considers the extent and duration of the unrealized loss and the financial condition and near-term prospects of the issuer. Management also considers whether the market decline was affected by macroeconomic conditions, and assesses whether the Company intends to sell, or it is more likely than not it will be required to sell a security in an unrealized loss position before recovery of its amortized cost basis. The assessment of whether OTTI exists involves a high degree of subjectivity and judgment and is based on the information available to management at a point in time.
	The second segment of the portfolio uses the OTTI guidance provided by ASC 325 that is specific to purchased beneficial interests that, on the purchase date, were rated below AA. Under the ASC 325 model, the Company compares the present value of the remaining cash flows as estimated at the preceding evaluation date to the current expected remaining cash flows. An OTTI is deemed to have occurred if there has been an adverse change in the remaining expected future cash flows.
	When OTTI occurs in either model, the amount of the impairment recognized in earnings depends on the Company’s intent to sell the security or if it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) other-than-temporary impairment related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities the entire amount of impairment is recognized through earnings.
	Federal Home Loan Bank (FHLB) and Federal Reserve Bank (FRB) Stock: The Bank is a member of the FHLB and FRB system. Members are required to own a certain amount of FHLB and FRB stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB and FRB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income.
	Conforming Mortgage Loans Held for Sale: Mortgage loans originated and intended for sale in the secondary market are carried at the fair value as of each balance sheet date, as determined by outstanding commitments from investors or what secondary markets are currently offering for portfolios with similar characteristics. The fair value includes the servicing value of the loans as well as any accrued interest. Mortgage loans held for sale are generally sold with servicing rights retained. Origination fees and costs are recognized in earnings at the time of origination for newly originated loans held for sale. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold.
	The Company’s conforming mortgage loans held for sale at fair value are Government-sponsored enterprise (GSE) or Government-eligible at December 31, 2014. These loans are considered to have reliable market price information and the fair value of these loans at December 31, 2014 was based on quoted market prices of similar assets and included the value of loan servicing.
	In scenarios of market disruptions, the current secondary market prices that are generally relied on to value GSE-eligible mortgage loans may not be readily available. In these circumstances, the Company may consider other factors, including: 1) quoted market prices for to-be-announced securities (for agency-eligible loans); 2) recent transaction settlements or traded but unsettled transactions for similar assets; 3) recent third party market transactions for similar assets; and 4) modeled valuations using assumptions that the Bank believes would be used by market participants in estimating fair value (assumptions may include prepayment rates, interest rates, volatilities, mortgage spreads and projected loss rates).
	Adjustments to reflect unrealized gains and losses resulting from changes in fair value and realized gains and losses upon ultimate sale of the loans are classified as part of Net Revenue on Mortgage Banking Activities on the Consolidated Statements of Operations.
	Non-Conforming Mortgage Loans Held for Sale: Non-conforming mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or fair value on an aggregate basis. A decline in the aggregate fair value of the loans below their aggregate carrying amount is recognized through a charge to earnings in the period of such a decline. Unearned income on the loans is taken into earnings when they are sold.
	SBA Loans Held for Sale: SBA loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated market value in the aggregate. Net unrealized losses are recognized through a valuation allowance by charges to income. Gains or losses realized on the sales of SBA loans are recognized at the time of sale and are determined by the difference between the net sales proceeds and the carrying value of the loans sold, adjusted for any servicing asset or liability. Gains and losses on sales of SBA loans are included in noninterest income.
	Loans and Leases: Loans and leases (other than purchased credit-impaired loans and leases) that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff are stated at the principal balance outstanding, net of charged off amounts and unamortized purchase premiums and discounts and net of deferred loan fees and costs. The deferred net loan fees and costs, and purchase premiums and discounts are recognized in interest income as an adjustment to yield over the loan term using the effective interest method. Interest on loans and leases is credited to interest income as earned based on the interest rate applied to principal amounts outstanding. Interest income is accrued on the unpaid principal balance and is discontinued on a loan when management believes, after considering economic and business conditions and collection efforts, that the borrower’s financial condition is such that full collection of principal or interest becomes doubtful, regardless of the length of past due status. Generally loans are placed on nonaccrual status when they are greater than 90 days past due. When interest accrual is discontinued, all unpaid accrued interest is reversed against interest income. Interest received on such loans and leases is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. A charge-off is recorded at 180 days if the loan balance exceeds the fair value of the collateral less costs to sell. Commercial, commercial real estate and equipment finance loans are subject to a detailed review when 90 days past due to determine accrual status, or when payment is uncertain and a specific consideration is made to put a loan or lease on non-accrual status. Consumer loans, other than those secured by real estate, are typically charged off no later than 180 days past due. Loans and leases are returned to accrual status when the borrower has demonstrated a satisfactory payment trend subject to management’s assessment of the borrower’s ability to repay the loan.
	Allowance for Loan and Lease Losses: The allowance for loan and lease losses is a reserve established through a provision for loan and lease loses charged to expense, and represents management’s best estimate of probable losses that may be incurred within the existing loan and lease portfolio as of the balance sheet date. Subsequent recoveries, if any, are credited to the allowance. The Company performs an analysis of the adequacy of the allowance at least on a quarterly basis. Management estimates the allowance balance required using past loan and lease 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 and leases, but the entire allowance is available for any loan or lease that, in management’s judgment, should be charged off.
	The allowance consists of three elements; (i) specific valuation allowances established for probable losses on impaired loans and leases, (ii) quantitative valuation allowances calculated using loss experience for like loans and leases with similar characteristics and trends, adjusted, as necessary to reflect the impact of current conditions; and (iii) qualitative allowances determined based on environmental and other factors that may be internal or external to the Company.
	A loan or lease 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 or lease agreement. The Company evaluates all impaired loans and leases individually under the guidance of ASC 310, Receivables, primarily through the evaluation of collateral values and estimated cash flows. Loans and leases for which the terms have been modified and where the borrower is experiencing financial difficulties are considered troubled debt restructurings (TDR) and classified as impaired.
	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 and leases 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 or lease 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. The impairment amount on a collateral dependent loan is charged-off to the allowance and the impairment amount on a loan that is not collateral dependent is set-up as a specific reserve. TDRs are also measured at the present value of estimated future cash flows using the loan’s or lease’s effective rate at inception or at the fair value of collateral, less costs to sell, if repayment is expected solely from the collateral. For TDRs that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the allowance for loan and lease losses.
	During the year ended December 31, 2014, the Company enhanced the current methodologies, processes and controls over the allowance for loan and lease losses (ALLL), due to the Company's organic and acquisitive growth and changing profile.
	The following is a synopsis of the enhancements for each component of ALLL:
	•	Expand the look-back period to 28 rolling quarters to capture a full economic cycle.
	•	Utilize net historical losses versus gross historical losses.
	•	Expand the peer group used to determine industry average loss history to include three industry groups; 1) all U.S. financial and bank holding companies, 2) all California financial and bank holding companies, 3) the peer group average from the Uniform Bank Performance Report.
	•	Apply a segment specific loss emergence period to each segment's loss rate.
	•	Determine qualitative reserves is at each loan segment level based on a baseline risk weighting adjusted for current risks, trends and business conditions.
	•	Disaggregate certain qualitative factors to be determined on the portfolio segment level.
	These enhancements resulted in an increase of $264 thousand in the ALLL as compared to what it would have been using the old methodology at December 31, 2014.
	At December 31, 2014, the following portfolio segments have been identified: commercial and industrial - secured; commercial and industrial - unsecured; commercial real estate - retail; commercial real estate - office; commercial real estate - industrial; commercial real estate - hospitality; commercial real estate - acquisition and development; commercial real estate - condo conversion; commercial real estate - other; construction; SBA; leases; single family residence -1st trust deed (amortizing, interest only now amortizing, interest only, negative amortization, and Green Loans); single family residence -2nd trust deeds; other consumer. The Company categorizes loans and leases into risk categories based on relevant information about the ability of borrowers and lessees (also referred to as borrowers) to service their obligations such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans and leases individually by classifying the loans and leases as to credit risk. This analysis includes all loans and leases delinquent over 60 days and non-homogeneous loans and leases such as commercial and commercial real estate loans. Classification of problem SFR mortgage loans is performed on a monthly basis while analysis of non-homogeneous loans is performed on a quarterly basis.
	Loans secured by multi-family and commercial real estate properties generally involve a greater degree of credit risk than SFR mortgage loans. Because payments on loans secured by multi-family and commercial real estate properties are often dependent on the successful operation or management of the properties, repayment of these loans may be subject to adverse conditions in the real estate market or the economy. Commercial business loans are also considered to have a greater degree of credit risk than SFR mortgage loans due to the fact commercial business loans are typically made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business. As a result, the availability of funds for the repayment of commercial business loans may be substantially dependent on the success of the business itself (which, in turn, is often dependent in part upon general economic conditions). SBA business loans are similar to commercial business loans, but have additional credit enhancement provided by the U.S. Small Business Administration, for up to 85 percent of the loan amount for loans up to $150,000 and 75 percent of the loan amount for loans of more than $150,000. Commercial equipment leases are also similar to commercial business loans in that the leases are typically made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business. As a result, the availability of funds for the repayment of commercial equipment leases may be substantially dependent on the success of the business itself (which, in turn, is often dependent in part upon general economic conditions). Consumer and other real estate loans may entail greater risk than do SFR mortgage loans given that collection of these loans is dependent on the borrower’s continuing financial stability and, thus, are more likely to be adversely affected by job loss, divorce, illness, or personal bankruptcy. Green Loans are also considered to carry a higher degree of credit risk due to their unique cash flows. Credit risk on this asset class is also managed through the completion of regular re-appraisals of the underlying collateral and monitoring of the borrower’s usage of this account to determine if the borrower is making monthly payments from external sources or “drawdowns” on their line. In cases where the property values have declined to levels less than the original loan-to-value, or other levels deemed prudent by the Company, the Company may curtail the line and/or require monthly payments or principal reductions to bring the loan in balance.
	Classified Assets: Federal regulations provide for the classification of loans, leases, and other assets, such as debt and equity securities considered to be of lesser quality, as “substandard,” “doubtful” or “loss.” An asset is considered “substandard” if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. “Substandard” assets include those characterized by the “distinct possibility” that the insured institution will sustain “some loss” if the deficiencies are not corrected. Assets classified as “doubtful” have all of the weaknesses inherent in those classified “substandard,” with the added characteristic that the weaknesses present make “collection or liquidation in full,” on the basis of currently existing facts, conditions, and values, “highly questionable and improbable.” Assets classified as “loss” are those considered “uncollectible” and of such little value that their continuance as assets without the establishment of a specific loss reserve is not warranted. When an insured institution classifies problem assets as “loss,” it is required to charge off such amount. The Bank’s determination as to the classification of its assets and the amount of its valuation allowances is subject to review by its primary regulator, which may order the establishment of additional general or specific loss allowances.
	Troubled Debt Restructurings (TDR): A loan is identified as a TDR when a borrower is experiencing financial difficulties and for economic or legal reasons related to these difficulties, the Company grants a concession to the borrower in the restructuring that it would not otherwise consider. The Company has granted a concession when, as a result of the restructuring to a troubled borrower, it does not expect to collect all amounts due, including principal and/or interest accrued at the original terms of the loan. The concessions may be granted in various forms, including a below-market change in the stated interest rate, a reduction in the loan balance or accrued interest, an extension of the maturity date, or a note split with principal forgiveness. Loans for which the borrower has been discharged under Chapter 7 bankruptcy are considered collateral dependent TDRs, impaired at the date of discharge, and charged down to the fair value of collateral less cost to sell. A restructuring executed at an interest rate that is at market interest rates based on the current credit characteristics of the borrower is not a TDR.
	The Company’s policy is to place consumer loan TDRs, except those that were performing prior to TDR status, on non-accrual status for a minimum period of 6 months. Commercial TDRs are evaluated on a case-by-case basis for determination of whether or not to place on non-accrual status. Loans qualify for return to accrual status once they have demonstrated performance with the restructured terms of the loan agreement for a minimum of 6 months. Initially, all TDRs are reported as impaired. Generally, TDRs are classified as impaired loans and reported as TDRs for the remaining life of the loan. Impaired and TDR classification may be removed if the borrower demonstrates compliance with the modified terms for a minimum of 6 months and through one fiscal year-end and the restructuring agreement specifies a market rate of interest equal to that which would be provided to a borrower with similar credit at the time of restructuring. In the limited circumstance that a loan is removed from TDR classification it is the Company’s policy to continue to base its measure of loan impairment on the contractual terms specified by the loan agreement.
	Concentration of Credit Risk: Most of the Company’s lending activity is with customers located within San Diego, Los Angeles, Orange and Riverside Counties, California. Therefore, the Company’s exposure to credit risk is significantly affected by economic conditions in those areas. Our loans are concentrated geographically in the Southern California market place.
	Purchased Credit-Impaired Loans: The Company purchases loans with and without evidence of credit quality deterioration since origination. Evidence of credit quality deterioration as of the purchase date may include statistics such as prior loan modification history, updated borrower credit scores and updated loan or lease-to-value (LTV) ratios, some of which may not be immediately available as of the purchase date. Purchased loans with evidence of credit quality deterioration where the Company estimates that it will not receive all contractual payments are accounted for as purchased credit impaired loans (PCI loans). The excess of the cash flows expected to be collected on PCI loans, measured as of the acquisition date, over the estimated fair value is referred to as the accretable yield and is recognized in interest income over the remaining life of the loan or lease using a level yield methodology. The difference between contractually required payments as of the acquisition date and the cash flows expected to be collected is referred to as the non-accretable difference. PCI loans that have similar risk characteristics, primarily credit risk, collateral type and interest rate risk, are pooled and accounted for as a single unit with a single composite interest rate and an aggregate expectation of cash flows.
	Loans that were acquired during 2012 in connection with the Beach and Gateway acquisitions and during 2013 in connection with the PBOC acquisition that were considered credit impaired were recorded at fair value at the acquisition date and the related allowance for loan and lease losses was not carried over to the Company’s allowance. Any losses on such loans are charged against the non-accretable difference established in purchase accounting and are not reported as charge-offs until such non-accretable difference is fully utilized. These loans were evaluated individually and were not part of the aforementioned pools.
	The Company estimates cash flows expected to be collected over the life of the loan using management’s best estimate which is derived using current key assumptions such as default rates, loss severity and payment speeds. If, upon subsequent evaluation, the Company determines it is probable that the present value of the expected cash flows have decreased due to a deterioration of credit, the PCI loan is considered further impaired which will result in a charge to the provision for loan and lease losses and a corresponding increase to the allowance for loan and lease losses. If, upon subsequent evaluation, it is probable that there is an increase in the present value of the expected cash flows, the Company will reduce any remaining allowance. If there is no remaining allowance, the Company will recalculate the amount of accretable yield as the excess of the revised expected cash flows over the current carrying value resulting in a reclassification from non-accretable difference to accretable yield. The present value of the expected cash flows for PCI purchased loan pools is determined using the PCI loans’ effective interest rate, adjusted for changes in the PCI loans’ interest rate indexes. Adjustments in interest rate assumptions and prepayment behavior do not impact the Company’s assessment of credit impairment. The present value of the expected cash flows for PCI loans and leases acquired through mergers with other banks includes, in addition to the above, an evaluation of the credit worthiness of the borrower. Loan dispositions may include sales of loans, receipt of payments in full from the borrower or foreclosure. Write-downs are not recorded on the PCI loan pool until actual losses exceed the remaining non-accretable difference. To date, no write-downs have been recorded for the PCI loans held by the Company.
	Other Real Estate Owned: Other real estate owned (OREO), which represents real estate acquired through foreclosure in satisfaction of commercial and real estate loans, is initially recorded at fair value less estimated selling costs of the real estate, based on current independent appraisals obtained at the time of acquisition, less costs to sell when acquired, establishing a new cost basis. Loan balances in excess of fair value of the real estate acquired at the date of acquisition are charged to the allowance for loan losses. Gains and losses on the sale of OREO are included in Net Gain on Sales of Other Real Estate Owned, reductions in fair value subsequent to foreclosure are included in Valuation Allowance for Other Real Estate Owned and any subsequent operating expenses or income of such properties are included in All Other Expense on the Consolidated Statements of Operations.
	Premises and Equipment: Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method with the following estimated useful lives: building 40 years and leasehold improvements-life of lease, and furniture, fixtures, and equipment 3 to 7 years. Maintenance and repairs are charged to expense as incurred, and improvements that extend the useful lives of assets are capitalized.
	Bank Owned Life Insurance: The Bank has purchased life insurance policies on certain key current and former executives. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
	Servicing Rights-Mortgage (Fair Value Method): A servicing asset or liability is recognized when undertaking an obligation to service a financial asset under mortgage servicing contract, including a transfer of the servicer’s financial assets that meet the requirements for sale accounting. Such servicing asset or liability is initially measured at fair value based on either market prices for comparable servicing contracts or alternatively is based on a valuation model that is based on the present value of the contractually specified servicing fee, net of servicing costs, over the estimated life of the loan, using a discount rate based on the related note rate and is recorded on the Consolidated Statements of Operations.
	Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income.
	Under the fair value measurement method, the Company measures servicing rights at fair value at each reporting date and reports changes in fair value of servicing assets in earnings in the period in which the changes occur, and are included with Net Revenue on Mortgage Banking Activities on the Consolidated Statements of Operations. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimates and actual prepayment speeds and default rates and losses. Currently the Company does not hedge the income statement effects of changes in fair value of the servicing assets.
	Servicing fee income, which is reported in Loan Servicing Income on the Consolidated Statements of Operations, is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal; or a fixed amount per loan and are recorded as income when earned. Late fees and ancillary fees related to loan servicing are not material.
	Servicing Rights-Small Business Administration Loans (Amortized Cost Method): As a general course of business, the Bank originates and sells the guaranteed portion of its SBA loans. To calculate the gain (loss) on sales of SBA loans, the Bank’s investment in the loan is allocated among the retained portion of the loan, the servicing retained, the interest-only strip and the sold portion of the loan, based on the relative fair market value of each portion. The gain (loss) on the sold portion of the loan is recognized at the time of sale based on the difference between sale proceeds and the amount of the allocated investment to the sold portion of the loan.
	The portion of the servicing fees that represent contractually specified servicing fees (contractual servicing) is reflected as a servicing asset and is amortized over the estimated life of the servicing; in the event future prepayments exceed management’s estimates and future expected cash flows are inadequate to cover the servicing asset, impairment is recognized. The portion of servicing fees in excess of contractual servicing fees are reflected as interest-only (I/O) strips receivable, which is included in Other Assets on the Consolidated Statements of Financial Condition. The I/O strips receivable are carried at fair value, with unrealized gains and losses recorded in the Consolidated Statements of Operations. The Company did not have any I/O strip receivable at December 31, 2014 and 2013.
	Goodwill and Other Intangible Assets: Goodwill represents the excess purchase price of businesses acquired over the fair value of the identifiable net assets acquired and is assigned to specific reporting units. Goodwill is not subject to amortization and is evaluated for impairment annually, during the third fiscal quarter, or more frequently in the interim if events occur or circumstances change indicating it would more likely than not result in a reduction of the fair value of a reporting unit below its carrying value. Goodwill is evaluated for impairment by either performing a qualitative evaluation or a two-step quantitative test. The qualitative evaluation is an assessment of factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. Discounted cash flow estimates, which include significant management assumptions relating to revenue growth rates, net interest margins, weighted average cost of capital, and future economic and market conditions, are used to determine fair value under the two-step quantitative test. In Step 1, the fair value of a reporting unit is compared to its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired, and it is not necessary to continue to Step 2 of the impairment process. Otherwise, Step 2 is performed where the implied fair value of goodwill is compared to the carrying value of goodwill in the reporting unit. If a reporting unit's carrying value exceeds fair value, the difference is charged to noninterest expense.
	Other intangible assets represent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights, or because the asset is capable of being sold or exchanged either separately or in combination with a related contract, asset or liability. Other intangible assets with finite useful lives are amortized to noninterest expense over their estimated useful lives and are evaluated for impairment whenever events occur or circumstances change indicating the carrying amount of the asset may not be recoverable.
	Affordable Housing Fund Investment: The Company has invested in two limited partnerships that were formed to develop and operate several apartment complexes designed as high-quality affordable housing for lower income tenants throughout the State of California and other states. The Company accounts for these investments under the equity method. The Company’s ownership in each limited partnership varies from 8 percent to 19 percent. At December 31, 2014 and 2013, the gross investments in these limited partnerships amounted to $9.0 million and $5.6 million, respectively, with original investment amount to be $9.5 million. The unfunded portion was $487 thousand at December 31, 2014. Each of the partnerships must meet the regulatory minimum requirements for affordable housing for a minimum 15-year compliance period to fully utilize the tax credits. If the partnerships cease to qualify during the compliance period, the credit may be denied for any period in which the project is not in compliance and a portion of the credit previously taken is subject to recapture with interest.
	The approximate future federal and state tax credits to be generated over a multiple-year period are $4.9 million and $5.6 million at December 31, 2014 and 2013, respectively. The Company had an unused tax credit carryforward of $0. Investment amortization amounted to $689 thousand and $569 thousand for the years ended December 31, 2014 and 2013 respectively.
	Reserve for Unfunded Commitments: The reserve for unfunded commitments provides for probable losses inherent with funding the unused portion of legal commitments to available to lend. The unfunded reserve calculation includes factors that are consistent with ALLL methodology for funded loans using the loss given default, probability of default and a draw down factor applied to the underlying borrower risk and facility grades. Changes in the reserve for unfunded credit commitments, within Accrued Expenses and Other Liabilities, is reported as a component of All Other Expense on the Consolidated Statements of Operations.
	Reserve for Loss on Repurchased Loans: In the ordinary course of business, as loans held for sale are sold, the Bank makes standard industry representations and warranties about the loans. The Bank may have to subsequently repurchase certain loans or reimburse certain investor losses due to defects that may have occurred in the origination of the loans. Such defects include documentation or underwriting errors. In addition, certain investor contracts require the Bank to repurchase loans from previous whole loan sales transactions that experience early payment defaults. If there are no such defects or early payment defaults, the Bank has no commitment to repurchase loans that it has sold. The level of reserve for loss on repurchased loans is an estimate that requires considerable management judgment. The Bank’s reserve is based upon the expected future repurchase trends for loans already sold in whole loan sale transactions and the expected valuation of such loans when repurchased, which include first and second trust deed loans. At the point when loss reimbursements are made directly to the investor, the reserve for loss reimbursements on sold loans is charged for the losses incurred.
	Business Combinations: Business combinations are accounted for under the acquisition method of accounting in accordance with ASC 805, Business Combinations. Under the acquisition method the acquiring entity in a business combination recognizes 100 percent of the acquired assets and assumed liabilities, regardless of the percentage owned, at their estimated fair values as of the date of acquisition. Any excess of the purchase price over the fair value of net assets and other identifiable intangible assets acquired is recorded as goodwill. To the extent the fair value of net assets acquired, including other identifiable assets, exceed the purchase price, a bargain purchase gain is recognized. Assets acquired and liabilities assumed from contingencies must also be recognized at fair value, if the fair value can be determined during the measurement period. Results of operations of an acquired business are included in the statement of operations from the date of acquisition. Acquisition-related costs, including conversion and restructuring charges, are expensed as incurred. The Company applied this guidance to the RenovationReady and BPNA Branch acquisitions that were consummated in 2014, the PBOC, The Palisades Group, and CS Financial acquisitions that were consummated in 2013, and the Gateway Bancorp and Beach Business Bank acquisitions that were consummated in 2012.
	Long-term Assets: Premises and equipment and other long-term assets are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.
	Deferred Financing Costs: Deferred financing costs associated with the Company’s senior notes and junior subordinated amortizing notes are included in Notes Payable on the Consolidated Statements of Financial Condition. The deferred financing costs are being amortized on a basis that approximates a level yield method over the eight-year term of the senior notes and the five-year term of the junior subordinated amortizing notes.
	Loan Commitments and Related Financial Statements: Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Stock-Based Compensation: Compensation cost is recognized for stock appreciation rights, stock options and restricted stock awards issued to employees and directors, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.
Income Taxes: Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance is established when necessary to reduce deferred tax assets when it is more-likely-than-not that a portion or all of the net deferred tax assets will not be realized. As of December 31, 2014, the Company had a net deferred tax asset of $16.4 million, net of a $0 valuation allowance and the Company had a net deferred tax asset of $0, net of a $17.3 million valuation allowance as of December 31, 2013. The decrease in the valuation allowance against its federal and state deferred tax assets was due primarily to current year taxable income, including strong core earnings and management’s projection of taxable income for future tax years. See further discussion in Note 13.
The Company and its subsidiaries are subject to U.S. Federal income tax as well as income tax in multiple state jurisdictions. The Company is no longer subject to examination by U.S. Federal taxing authorities for years before 2010, with the exception of Gateway Bancorp, a predecessor entity, which is currently under exam by the Internal Revenue Service for the 2008 and 2009 tax years. The statute of limitations for the assessment of California Franchise taxes has expired for tax years before 2010; other state income and franchise tax statutes of limitations vary by state.
Tax positions that are uncertain but meet a more likely than not recognition threshold are initially and subsequently measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position meets the more likely than not recognition threshold considers the facts, circumstances and information available at the reporting date and is subject to management's judgment. The Company recognizes interest and/or penalties related to income tax matters in income tax expense. The Company had $23 thousand and $0 accrued for interest and penalties at December 31, 2014 and 2013, respectively.
Earnings Per Common Share: Earnings per common share is computed under the two-class method. Basic earnings per common share (EPS) is computed by dividing net income allocated to common stockholders by the weighted average number of shares outstanding, including the minimum number of shares issuable under purchase contracts relating to the tangible equity units (see the discussion of the tangible equity units in Note 18). Diluted EPS is computed by dividing net income allocated to common stockholders by the weighted average number of shares outstanding, adjusted for the dilutive effect of the restricted stock units, the potentially issuable shares in excess of the minimum under purchase contracts relating to the tangible equity units, outstanding stock options, and warrants to purchase common stock. Net income allocated to common stockholders is computed by subtracting income allocated to participating securities, participating securities dividends and preferred stock dividend from net income. Participating securities are instruments granted in share-based payment transactions that contain rights to receive nonforfeitable dividends or dividend equivalents, which includes the Stock Appreciation Rights to the extent they confer dividend equivalent rights, as described under “Stock Appreciation Rights” in Note 16.
Comprehensive Income (Loss): Comprehensive income (loss) consists of net income (loss) and other comprehensive income or loss. Other comprehensive income or loss includes unrealized gains and losses on securities available for sale and interest rate swap, net of tax, which are recognized as a separate component of stockholders’ equity.
Accounting for Derivative Instruments and Hedging Activities: The Company records its derivative instruments at fair value as either assets or liabilities on the Consolidated Statements of Financial Condition in other assets and accrued expenses and other liabilities, respectively. The change in derivative instruments fair value is recorded in current earnings in Net Revenue on Mortgage Banking Activities on the Consolidated Statements of Operations.
The Company enters into commitments to originate mortgage loans whereby the interest rate on the loan is set prior to funding (interest rate lock commitments, or IRLCs). Interest rate lock commitments on mortgage loans that are intended to be sold are considered derivatives and are recorded at fair value in Other Assets or Accrued Expenses and Other Liabilities on the Consolidated Statements of Financial Condition with the change in fair value recorded in the Consolidated Statements of Operations. The estimated fair value is based on current market prices for similar instruments.
The Company hedges the risk of the overall change in the fair value of loan commitments to borrowers by selling forward contracts on securities of GSEs. Forward contracts on securities are considered derivative instruments. The Company has not formally designated these derivatives as a qualifying hedge relationship and accordingly, accounts for such forward contracts as freestanding derivatives with changes in fair value recorded to earnings each period.
Loss Contingencies: Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there now are such matters that will have a material effect on the consolidated financial statements.
Dividend Restriction: Banking regulations require maintaining certain capital levels and may limit the dividends paid by the Bank to the Company or by the Company to stockholders.
Fair Values of Financial Instruments: The Company measures certain assets and liabilities on a fair value basis, in accordance with ASC Topic 820, "Fair Value Measurement". Fair value is used on a recurring basis for certain assets and liabilities in which fair value is the primary basis of accounting. Examples of these include derivative instruments and available for sale securities. Additionally, fair value is used on a non-recurring basis to evaluate assets or liabilities for impairment in accordance with ASC Topic 825, "Financial Instruments". Examples of these include impaired loans, long-lived assets, OREO, goodwill, and core deposit intangible assets as well as loans held for sale accounted for at the lower of cost or fair value.
Fair value is the exchange price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants. When observable market prices are not available, fair value is estimated using modeling techniques such as discounted cash flow analysis. These modeling techniques utilize assumptions that market participants would use in pricing the asset or the liability, including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset, and the risk of nonperformance. Depending on the nature of the asset or liability, the Company uses various valuation techniques and assumptions when estimating the instrument’s fair value. Considerable judgment may be involved in determining the amount that is most representative of fair value.
To increase consistency and comparability of fair value measures, ASC Topic 820, "Fair Value Measurement" established a three-level hierarchy to prioritize the inputs used in valuation techniques between observable inputs among (i) observable inputs that reflect quoted prices in active markets, (ii) inputs other than quoted prices with observable market data, and (iii) unobservable data such as the Company’s own data or single dealer non-binding pricing quotes. The Company assesses the valuation hierarchy for each asset or liability measured at the end of each quarter, as a result assets or liabilities may be transferred within hierarchy levels due to changes in availability of observable market inputs to measure fair value at the measurement date. Further information regarding the Company's policies and methodology used to measure fair value is presented in Note 3.
Transfer of Financial Assets: Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is generally considered to have been surrendered when (i) the transferred assets are legally isolated from the Company or its consolidated affiliates, even in bankruptcy or other receivership, (ii) the transferee has the right to pledge or exchange the assets with no conditions that constrain the transferee and provide more than a trivial benefit to the Company, and (iii) the Company does not maintain the obligation or unilateral ability to reclaim or repurchase the assets.
The Company sells financial assets in the normal course of business, the majority of which are residential mortgage loan sales primarily to government-sponsored enterprises through established programs and other individual or portfolio loan and securities sales. In accordance with accounting guidance for asset transfers, the Company considers any ongoing involvement with transferred assets in determining whether the assets can be derecognized from the balance sheet. With the exception of servicing and certain performance-based guarantees, the Company’s continuing involvement with financial assets sold is minimal and generally limited to market customary representation and warranty clauses.
When the Company sells financial assets, it may retain servicing rights and/or other interests in the financial assets. The gain or loss on sale depends on the previous carrying amount of the transferred financial assets and the consideration received and any liabilities incurred in exchange for the transferred assets. Upon transfer, any servicing assets and other interests held by the Company are carried at the lower of cost or fair value.
Fee Revenue: Generally, fee revenue from deposit service charges and loans is recognized when earned, except where ultimate collection is uncertain, in which case revenue is recognized when received.
Marketing Costs: Marketing costs are expensed as incurred.
Investment Advisory Performance Fees: The Company’s SEC-registered investment advisor, The Palisades Group, receives investment advisory performance fees from actively managed investment funds. Certain performance fees are not finalized until the end of a period of time specified in the contracts. Such fees are recognized only to the extent that the amounts will not be reversed due to clawback provisions.
Correction of Prior Period Errors: During the year ended December 31, 2014, the Company made cumulative prior period (years ended December 31, 2013 and 2012) adjustments related to the provision for loan repurchases, the allowance for loan and lease losses, restricted stock compensation expense, and other expenses, which increased the provision for loan repurchases by $571 thousand, provision for loan and lease losses by $1.2 million, and other expense by $353 thousand, and decreased stock compensation expense by $234 thousand. The Company reviewed the impact of these corrections in accordance with Securities Exchange Commission Staff Accounting Bulletin No. 99 “Materiality”, and determined that the corrections were not material to prior or current periods.
Adoption of New Accounting Standards
In January 2014, the FASB issued guidance within ASU 2014-1, “Accounting for Investments in Qualified Affordable Housing Projects.” The amendments in ASU 2014-1to Topic 323, “Equity Investments and Joint Ventures,” provide guidance on accounting for investments by a reporting entity in flow-through limited liability entities that manage or invest in affordable housing projects that qualify for the low-income housing tax credit. The amendments permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received, and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). The amendments are effective for fiscal years, and interim periods within those years, beginning after December 31, 2014 and should be applied retrospectively to all periods presented. Early adoption is permitted. All of the Company’s affordable housing fund investments are within the scope of this guidance. The Company does not expect the application of this guidance to have a material impact on the Company's financial statements.
In January 2014, the FASB issued ASU No. 2014-4, “Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure.” ASU 2014-4 clarifies that an in substance repossession or foreclosure has occurred, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure. Interim and annual disclosure is required of both the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure. ASU 2014-4 is effective using either the modified retrospective transition method or a prospective transition method for fiscal years and interim periods within those years, beginning after December 15, 2014, and early adoption is permitted. The Company does not expect the application of this guidance to have a material impact on the Company's financial statements.
In May 2014, the FASB issued ASU No. 2014-9, “Revenue From Contracts With Customers”, that outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The ASU is based on the principle that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to fulfill a contract. Entities have the option of using either a full retrospective or a modified retrospective approach for the adoption of the new standard. The ASU becomes effective for Company at the beginning of its 2017 fiscal year; early adoption is not permitted. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements.
In June 2014, the FASB issued ASU No. 2014-11, “Transfers and Servicing: Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures”. The ASU changes the accounting for repurchase-to-maturity transactions to secured borrowing accounting. In addition, for repurchase financing arrangements, the amendments require separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. The ASU also requires disclosures for certain transactions comprising (1) a transfer of a financial asset accounted for as a sale and (2) an agreement with the same transferee entered into in contemplation of the initial transfer that results in the transferor retaining substantially all of the exposure to the economic return on the transferred financial asset throughout the term of the transaction. There are also additional disclosure requirements for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions that are accounted for as secured borrowings. ASU 2014-11 is effective using either the modified retrospective transition method or a prospective transition method for fiscal years and interim periods within those years, beginning after December 15, 2014. The Company does not expect the application of this guidance to have a material impact on the Company's financial statements.
In June 2014, the FASB issued ASU No. 2014-12, “Compensation—Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period”. The ASU requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Topic 718 as it relates to awards with performance conditions that affect vesting to account for such awards. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. ASU 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements.
In August 2014, the FASB issued ASU 2014-14, “Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310-40), Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure.” Under ASU 2014-14, a mortgage loan should be derecognized and a separate receivable based on the principal and interest expected to be recovered from the governmental guarantor should be recognized upon foreclosure when all of the following conditions exist: a government guarantee exists that is not separable from the loan prior to the foreclosure; as of the date of the foreclosure the creditor has the intent to convey the real estate to the governmental agency that issued the guarantee, to make a claim on the guarantee and the creditor has the ability to recover amounts due from the governmental entity as a result of the claim; and, as of the time of the foreclosure, the claim amount that is based on the fair value of the real estate is fixed. ASU 2014-14 is effective using either the modified retrospective transition method or a prospective transition method for fiscal years and interim periods within those years, beginning after December 15, 2014. The Company does not expect the application of this guidance to have a material impact on the Company's financial statements.

	Banco Popular’s California Branch Network Acquisition
	Effective November 8, 2014, the Bank acquired 20 full-service branches from Banco Popular North America (BPNA) in the Southern California banking market, as contemplated by the Purchase and Assumption Agreement between the Bank and BPNA dated as of April 22, 2014 (the Purchase Agreement). The purchase price, net of deposit premiums received of $3.9 million, was $24.0 million. The transaction added $1.07 billion in loans and $1.08 billion in deposits to the Bank.
	The following table summarizes the total consideration transferred as a part of the BPNA Branch Acquisition as well as the fair value adjustments to the BPNA balance sheet as of the respective acquisition date:
		8-Nov-14
		(In thousands)
	Total Consideration				$	27,941
	Net assets pre-acquisition				24,027
	Fair value adjustments
	Loans receivable	$	(12,165	)
	Core Deposit Intangibles	15,777
	Certificates of deposit purchase premium	(916		)
	Premises and equipment	1,218
	Total fair value adjustments				3,914
	Fair value of net assets acquired				27,941
	Net fair value in excess of consideration				$	—
	The fair value of loans acquired from BPNA was estimated by utilizing a methodology wherein similar loans were aggregated into pools. Cash flows for each pool were determined by estimating future credit losses and the rate of prepayments. Projected monthly cash flows were then discounted to present value based on a market rate for similar loans. There was no carryover of BPNA's allowance for loan losses associated with the acquired loans as the loans were initially recorded at fair value.
	Core deposit intangible asset of $15.8 million recognized as part of the BPNA Branch Acquisition was valued using a net cost savings method and was calculated as the present value of the estimated net cost savings attributable to the core deposit base over the expected remaining life of the deposits. The cost savings derived from the core deposit balance was calculated as the difference between the prevailing alternative cost of funds and the estimated actual cost of the core deposits. The core deposit intangible is being amortized over its estimated useful life of ten years using the sum of years-digits amortization methodology.
	The fair value of savings and transaction deposit accounts acquired from BPNA was assumed to approximate the carrying value as these accounts have no stated maturity and are payable on demand. Certificates of deposit were valued by projecting out the expected cash flows based on the remaining contractual terms of the certificates of deposit. These cash flows were discounted based on market rates for certificates of deposit with corresponding remaining maturities.
	Direct costs related to the BPNA Branch Acquisition were expensed as incurred and amounted to $4.3 million for the year ended December 31, 2014. These acquisition integration expenses included technology costs related to system conversion and professional fees.
	Certain valuations related to acquired loans receivable, premises and equipment, and other intangible assets and assumed deposits are still under review by management and considered preliminary and could differ significantly when management's review is finalized.
	RenovationReady® Acquisition
	Effective January 31, 2014, the Company acquired certain assets, including service contracts and intellectual property, of RenovationReady, a provider of specialized loan services to financial institutions and mortgage bankers that originate agency eligible residential renovation and construction loan products.
	The purchased identifiable intangible assets and assumed liabilities were recorded at their estimated fair values as of January 31, 2014. The Company recorded $2.2 million of goodwill and $761 thousand of other intangible assets. The other intangible assets are related to a customer relationship intangible.
	CS Financial Acquisition
	Effective October 31, 2013, the Company acquired CS Financial, Inc. (CS Financial), a California corporation and Southern California-based mortgage banking firm controlled by former Company director and current Bank executive Jeffrey T. Seabold. As a result of the acquisition, CS Financial became a wholly owned subsidiary of the Bank. For additional information regarding this transaction, see Note 25.
The purchased assets, including identifiable intangible assets, and assumed liabilities were recorded at their estimated fair values as of October 31, 2013. The Company recorded $7.2 million of goodwill and $690 thousand of other intangible assets. The other intangible assets are related to a trade name intangible.
The Palisades Group, LLC Acquisition
Effective September 10, 2013, the Company acquired The Palisades Group, a Delaware limited liability company and a registered investment adviser under the Investment Advisers Act of 1940, pursuant to the terms of the Amended and Restated Units Purchase Agreement dated as of November 30, 2012, amended and restated as of August 12, 2013, for $50 thousand. The Palisades Group provides financial advisory and asset management services to third parties, including the Bank, with respect to the purchase, sale and management of portfolios of residential mortgage loans.
The Palisades Group acquisition was accounted for under GAAP guidance for business combinations. The assets and liabilities were recorded at their estimated fair values as of the September 10, 2013 acquisition date. No goodwill was recognized.
The Private Bank of California Acquisition
Effective July 1, 2013, the Company completed its acquisition of The Private Bank of California, (PBOC) pursuant to the terms of the Agreement and Plan of Merger, dated as of August 21, 2012, as amended (the PBOC Merger Agreement), by and between the Company, Beach Business Bank (Beach) (then a separate subsidiary bank of the Company) and PBOC. PBOC merged with and into Beach, with Beach continuing as the surviving entity in the merger and a wholly owned subsidiary of the Company, and changing its name to “The Private Bank of California.” On October 11, 2013, The Private Bank of California was merged with the Company’s other wholly owned banking subsidiary, Banc of California, National Association (formerly Pacific Trust Bank), to form the Bank.
Pursuant to the terms of the PBOC Merger Agreement, the Company paid aggregate merger consideration of (1) 2,082,654 shares of Company common stock (valued at $28.3 million based on the $13.58 per share closing price of Company common stock on July 1, 2013), and (2) $25.4 million in cash. Additionally, the Company paid $2.7 million for the cancellation of certain outstanding options to acquire PBOC common stock in accordance with the PBOC Merger Agreement and converted the remaining outstanding PBOC stock options to Company stock options with an assumed fair value of approximately $30 thousand. On the basis of the number of shares of PBOC common stock issued and outstanding immediately prior to the completion of the merger, each outstanding share of PBOC common stock was converted into the right to receive $6.52 in cash and 0.5379 shares of Company common stock.
In addition, upon completion of the acquisition, each share of preferred stock issued by PBOC as part of the Small Business Lending Fund (SBLF) program of the United States Department of Treasury (10,000 shares in the aggregate with a liquidation preference amount of $1,000 per share) was converted automatically into one substantially identical share of preferred stock of the Company. The terms of the preferred stock issued by the Company in exchange for the PBOC preferred stock are substantially identical to the preferred stock previously issued by the Company as part of its own participation in the SBLF program (32,000 shares in aggregate with a liquidation preference amount of $1,000 per share).
PBOC provided a range of financial services, including credit and deposit products as well as cash management services, from its headquarters located in the Century City area of Los Angeles, California as well as full-service branches in Hollywood and Irvine, and a loan production office in downtown Los Angeles. PBOC’s target clients included high-net worth and high income individuals, business professionals and their professional service firms, business owners, entertainment service businesses and non-profit organizations.
In accordance with GAAP guidance for business combinations, the Company expensed approximately $2.6 million of direct acquisition costs, all of which were recognized in 2013, and recorded $15.1 million of goodwill and $10.4 million of other intangible assets. The other intangible assets are primarily related to core deposits and are being amortized on an accelerated basis over 2-7 years. Loans acquired from PBOC that were considered credit impaired were written down to fair value at the acquisition date in accordance with purchase accounting. In addition, the allowance for loan losses for all PBOC loans was not carried over to the Company’s allowance for loan and lease losses. A full valuation allowance for the deferred tax asset was recorded based on management’s evaluation of the expectation of recovery of deferred tax assets for the Company. For tax purposes, purchase accounting adjustments, including goodwill are all nontaxable and/or non-deductible.
Gateway Bancorp Acquisition
Effective August 18, 2012, the Company acquired Gateway Bancorp, the holding company of Gateway Business Bank (Gateway) pursuant to the terms of the Stock Purchase Agreement (the Purchase Agreement) dated June 3, 2011, as amended on November 28, 2011, February 24, 2012, June 30, 2012, and July 31, 2012. The acquisition was accomplished by the Company’s purchase of all of the outstanding stock of Gateway Bancorp, followed by the merger of Gateway into the Bank. Under the terms of the Purchase Agreement, the Company purchased all of the issued and outstanding shares of Gateway Bancorp for $15.4 million in cash.
Gateway operated branches in Lakewood and Laguna Hills, California. As part of the acquisition, Mission Hills Mortgage Bankers, a division of Gateway, including its 22 loan production offices in California, Arizona, Oregon and Washington, became a part of the Bank’s mortgage banking operations. Gateway’s consolidated assets and equity as of August 17, 2012 totaled $178.0 million and $27.0 million, respectively. The acquired assets and liabilities were recorded at fair value at the date of acquisition.
In accordance with GAAP guidance for business combinations, the Company recorded $11.6 million of bargain purchase gain and $1.7 million of other intangible assets during the year ended December 31, 2012. The other intangible assets are related to $720 thousand of core deposits, which are being amortized on an accelerated basis over 4 - 6 years, and $955 thousand of trade name intangible which is being amortized over 20 years. For tax purposes the purchase accounting adjustments and bargain purchase gain are non-taxable and/or non-deductible. Due to circumstances that Gateway faced at the time the acquisition was negotiated, which include regulatory orders and operating losses, the terms negotiated included a purchase price that was $5 million lower than Gateway Bancorp’s equity book value. The discount was further increased to $6.5 million in exchange for the elimination of any contingent liability to the stockholder of Gateway Bancorp related to mortgage repurchase risk. Due to delays in obtaining regulatory approval, the transaction closed nine months later than originally planned. This passage of time allowed Gateway to eliminate all regulatory orders, return to profitability, improve asset quality, and increase the book value of equity by reducing the expected discount on assets. As a result, a bargain purchase gain of $11.6 million resulted at the time of purchase.
Beach Business Bank Acquisition
Effective July 1, 2012, the Company acquired Beach Business Bank pursuant to the terms of the Agreement and Plan of Merger (the Merger Agreement) dated August 30, 2011, as amended October 31, 2011. At the effective time of the transaction, a newly formed and wholly owned subsidiary of the Company (Merger Sub) merged with and into Beach (the Merger), with Beach continuing as the surviving entity in the Merger and a wholly owned subsidiary of the Company. Pursuant and subject to the terms of the Merger Agreement, each outstanding share of Beach common stock (other than specified shares owned by the Company, Merger Sub or Beach, and other than in the case of shares in respect of, or underlying, certain Beach options and other equity awards, which were treated as set forth in the Merger Agreement) was converted into the right to receive $9.21415 in cash and one warrant. Each warrant entitled the holder to purchase 0.33 of a share of Company common stock at an exercise price of $14.00 per share for a period of one year. The aggregate cash consideration paid to Beach stockholders in the Merger was approximately $39.1 million. In addition, Beach stockholders received in aggregate warrants to purchase the equivalent of 1,401,959 shares of the Company’s common stock with an estimated fair value of $1.0 million. All of the warrants expired on June 30, 2013 without being exercised.
Beach (re-named The Private Bank of California effective July 1, 2013 and merged with Pacific Trust Bank on October 11, 2013 to form the Bank) operated branches in Manhattan Beach, Long Beach, and Costa Mesa, California. Beach also had a division named The Doctors Bank®, which serves physicians and dentists nationwide. Additionally, Beach provided loans to small businesses based on Small Business Administration (SBA) lending programs. Beach’s consolidated assets and equity (unaudited) as of June 30, 2012 totaled $311.9 million and $33.3 million, respectively. The acquired assets and liabilities were recorded at fair value at the date of acquisition.
In accordance with GAAP guidance for business combinations, the Company recorded $7.0 million of goodwill and $4.5 million of other intangible assets during the year ended December 31, 2012. The other intangible assets are primarily related to core deposits and are being amortized on an accelerated basis over 2 - 7 years. For tax purposes purchase accounting adjustments, including goodwill are all non-taxable and/or non-deductible.

Fair Value Disclosures [Abstract]
FAIR VALUES OF FINANCIAL INSTRUMENTS	FAIR VALUES OF FINANCIAL INSTRUMENTS
	Fair Value Hierarchy
	ASC 820-10 establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The topic describes three levels of inputs that may be used to measure fair value:
	•	Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.
	•	Level 2: Significant observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.
	•	Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.
	Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
	Assets and Liabilities Measured on a Recurring Basis
	Securities Available for Sale: The fair values of securities available for sale are generally determined by quoted market prices in active market, if available (Level 1). If quoted market prices are not available, the Company employs an independent pricing service that utilizes matrix pricing to calculate fair value. Such fair value measurements consider observable data such as dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayments speeds, credit information, and respective terms and conditions for debt instruments. The Company employs procedures to monitor the pricing service's assumptions and establishes processes to challenge the pricing service's valuations that appear unusual or unexpected. Level 2 securities include SBA loan pool securities, U.S. GSE and agency securities, Private label residential MBS, and Agency MBS. When a market is illiquid or there is a lack of transparency around the inputs to valuation, the securities are classified as Level 3 and reliance is placed upon internally developed models, and management judgment and evaluation for valuation. The Company had no securities available for sale classified as Level 3 at December 31, 2014 and 2013.
	Loans Held for Sale, carried at fair value: The fair value of loans held for sale is based on commitments outstanding from investors as well as what secondary markets are currently offering for portfolios with similar characteristics. Therefore, loans held for sale subjected to recurring fair value adjustments are classified as Level 2. The fair value includes the servicing value of the loans as well as any accrued interest.
	Derivative Assets and Liabilities: The Company’s derivative assets and liabilities are carried at fair value as required by GAAP and are accounted for as freestanding derivatives. The Company has entered into pay-fixed, receive-variable interest rate swap contracts with institutional counterparties to hedge against variability in cash flow attributable to interest rate risk caused by changes in the LIBOR benchmark interest rate on the Company’s ongoing LIBOR-based variable rate deposits. The Company is accounting for the swaps as cash flow hedges under ASC 815. The other derivative assets are interest rate lock commitments (IRLCs) with prospective residential mortgage borrowers. These commitments are carried at fair value based on the fair value of the underling mortgage loans which are based on observable market data. The Company adjusts the outstanding IRLCs with prospective borrowers based on an expectation that it will be exercised and the loan will be funded. Changes in fair value are recorded in earnings as a component of net revenue on mortgage banking activities. These commitments are classified as Level 2 in the fair value disclosures, as the valuations are based on market observable inputs. Additional derivative assets and liabilities, typically mortgage-backed to-be-announced (TBA) securities, are used to hedge fair value changes, driven by changes in interest rates, on the Company’s mortgage assets. The Company hedges the period from the interest rate lock (assuming a fall-out factor) to the date of the loan sale. The estimated fair value is based on current market prices for similar instruments. Given the meaningful level of secondary market activity for derivative contracts, active pricing is available for similar assets and accordingly, the Company classifies its derivative assets and liabilities as Level 2.
	Mortgage Servicing Rights: The Company retains servicing on some of its mortgage loans sold and elected the fair value option for valuation of these mortgage servicing rights (MSRs). The value is based on a third party provider that calculates the present value of the expected net servicing income from the portfolio based on key factors that include interest rates, prepayment assumptions, discount rate and estimated cash flows. Because of the significance of unobservable inputs, these servicing rights are classified as Level 3. At December 31, 2014, $5.9 million of the mortgage servicing rights is valued based on a market bid that settled subsequent to year end, which is included as Level 3.

mortgage-backed securities						Collateral default rate	8.46% to 8.56% (8.5%)
						Loss severity at default	55%
The significant unobservable inputs used in the fair value measurement of the Company’s servicing rights include the discount rate and estimated cash flow. There may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results.
Assets and Liabilities Measured on a Non-Recurring Basis
Impaired Loans and Leases: The fair value of impaired loans and leases with specific allocations of the allowance for loan and lease losses based on collateral values is generally based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value.
Loans Held for Sale, carried at lower of cost or fair value: The Company records non-conforming jumbo mortgage loans held for sale at the lower of cost or fair value. The Company obtains fair values from a third party independent valuation service provider. Loans held for sale are accounted for at the lower of cost or market and are considered to be recognized at fair value when they are recorded at below cost and are classified as Level 2.
SBA Servicing Assets: SBA servicing assets represents the value associated with servicing SBA loans that have been sold. The fair value for SBA servicing assets is determined through discounted cash flow analysis and utilizes discount rates and prepayment speed assumptions as inputs. All of these assumptions require a significant degree of management estimation and judgment. The fair market valuation is performed on a quarterly basis for SBA servicing assets. SBA servicing assets are account for at the lower of cost or market and considered to be recognized at fair value when they are recorded at below cost and are classified as Level 3.
Other Real Estate Owned Assets: Other real estate owned assets (OREO) are recorded at the fair value less estimated costs to sell at the time of foreclosure. The fair value of other real estate owned assets is generally based on recent real estate appraisals adjusted for estimated selling costs. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments may be significant and result in a Level 3 classification of the inputs for determining fair value. Only OREO with a valuation allowance are considered to be carried at fair value. For the years ended December 31, 2014, 2013 and 2012, the Company experienced $32 thousand, $97 thousand and $703 thousand in valuation allowance expense for those assets, respectively.
Alternative Investments (Affordable Housing Fund Investment & SBIC): The Company generally accounts for its percentage ownership of alternative investment funds at cost, subject to impairment testing. These are non-public investments that cannot be redeemed since the Company’s investment is distributed as the underlying investments are liquidated, which generally takes 10 years. There are currently no plans to sell any of these investments prior to their liquidation. The alternative investments carried at cost are considered to be measured at fair value on a non-recurring basis when there is impairment. The Company has unfunded commitments of $487 thousand and $4.7 million for Affordable House Fund Investment and SBIC as of December 31, 2014, respectively.

The methods and assumptions used to estimate fair value are described as follows:
Cash and cash equivalents and time deposits in financial institutions: The carrying amounts of cash and cash equivalents and time deposits in financial institutions approximate fair value due to the short-term nature of these instruments (Level 1).
FHLB and other bank stock: FHLB and other bank stock is recorded at cost. Ownership of FHLB stock is restricted to member banks, and purchases and sales of these securities are at par value with the issuer.
Loans and leases receivable, net of allowance for loan and lease losses: The fair value for loans receivable is estimated based on the discounted cash flow approach. The discount rate was derived from the associated yield curve plus spreads and reflects the offering rates offered by the Bank for loans with similar financial characteristics. Yield curves are constructed by product and payment types. These rates could be different from what other financial institutions could offer for these loans. No adjustments have been made for changes in credit within the loan portfolio. Additionally, the fair value of our loans may differ significantly from the values that would have been used had a ready market existed for such loans and may differ materially from the values that we may ultimately realize (Level 3).
Accrued interest receivable: The carrying amount of accrued interest receivable approximates its fair value (Level 1).
Deposits: The fair value of deposits is estimated based on discounted cash flows. The cash flows for non-maturity deposits, including savings accounts and money market checking, are estimated based on their historical decaying experiences. The discount rate used for fair valuation is based on interest rates currently being offered by the Bank on comparable deposits as to amount and term (Level 3).
Advances from Federal Home Loan Bank: The fair value of advances from FHLB is estimated based on the discounted cash flows approach. The discount rate was derived from the current market rates for borrowings with similar remaining maturities (Level 2).
Accrued interest payable: The carrying amount of accrued interest payable approximates its fair value (Level 1).

	The following table presents amortized cost and fair value of the available-for-sale investment securities portfolio by expected maturity. In the case of residential mortgage-backed securities and SBA loan pool securities, expected maturities may differ from contractual maturities because borrowers generally have the right to call or prepay obligations with or without call or prepayment penalties. For that reason, mortgage-backed securities and SBA loan pool securities are not included in the maturity categories.

The Company did not record other-than-temporary impairment (OTTI) for securities available for sale for the years ended December 31, 2014, 2013 and 2012.
At December 31, 2014, the Company’s securities available for sale portfolio consisted of 92 securities, 49 of which were in an unrealized loss position. The unrealized losses are related to an overall increase in interest rates and a decrease in prepayment speeds of the agency mortgage-backed securities.
The Company monitors to ensure it has adequate credit support and as of December 31, 2014, the Company did not have the intent to sell these securities and it is not likely that it will be required to sell the securities before their anticipated recoveries. Of the Company’s $345.7 million securities portfolio, $344.4 million were rated AAA, AA or A, $1.1 million were rated BBB, and a private label residential mortgage-backed security of $181 thousand was rated BB based on the most recent credit rating from the rating agencies as of December 31, 2014. The BB rated private label residential mortgage-backed security was subsequently sold during January 2015. The Company considers the lowest credit rating for identification of potential OTTI.

	Non Traditional Mortgage Loans
	The Company’s non-traditional mortgage (NTM) portfolio is comprised of three interest only products: Green Account Loans (Green Loans), fixed or adjustable hybrid interest only rate mortgage (Interest Only) loans and a small number of additional loans with the potential for negative amortization. As of December 31, 2014 and 2013, the non-traditional mortgage loans totaled $350.6 million, or 8.9 percent of the total loans and leases, and $309.6 million, or 12.7 percent of the total loans and leases, respectively. The total NTM portfolio increased by $41.0 million, or 13.2 percent, during the year ended December 31, 2014.

	Green Loans
	Green Loans are single family residential first and second mortgage lines of credit with a linked checking account that allows all types of deposits and withdrawals to be performed. The loans are generally interest only with a 15 year balloon payment due at maturity. At December 31, 2014 and 2013, Green Loans totaled $128.2 million and $153.0 million, respectively. As of December 31, 2014 and 2013, $12.5 million and $5.7 million, respectively, of the Company’s Green Loans were non-performing. As a result of their unique payment feature, Green Loans possess higher credit risk due to the potential of negative amortization; however, management believes the risk is mitigated through the Company’s loan terms and underwriting standards, including its policies on loan-to-value ratios and the Company’s contractual ability to curtail loans when the value of the underlying collateral declines. The Company discontinued origination of the Green Loan products in 2011.
	Interest Only Loans
	Interest only loans are primarily single family residential first mortgage loans with payment features that allow interest only payments in initial periods before converting to a fully amortizing loan. As of December 31, 2014 and 2013, interest only loans totaled $209.3 million and $140.0 million, respectively. As of December 31, 2014 and 2013, $2.0 million and $752 thousand of the interest only loans were non-performing, respectively.
	Loans with the Potential for Negative Amortization
	Negative amortization loans totaled $13.1 million and $16.6 million at December 31, 2014 and 2013, respectively. The Company discontinued origination of negative amortization loans in 2007. As of December 31, 2014 and 2013, $0 and $1.2 million of the loans that had the potential for negative amortization were non-performing, respectively. These loans pose a potentially higher credit risk because of the lack of principal amortization and potential for negative amortization; however, management believes the risk is mitigated through the loan terms and underwriting standards, including the Company’s policies on loan-to-value ratios.
Risk Management of Non-Traditional Mortgages
The Company has determined that the most significant performance indicators for non-traditional mortgages are loan-to-value (LTV) and FICO scores. Accordingly, the Company manages credit risk in the NTM portfolio through semi-annual review of the loan portfolio that includes refreshing FICO scores on the Green Loans and home equity lines of credit, as needed in conjunction with portfolio management, and ordering third party automated valuation models. The loan review is designed to provide a method of identifying borrowers who may be experiencing financial difficulty before they actually fail to make a loan payment. Upon receipt of the updated FICO scores, an exception report is run to identify loans with a decrease in FICO of 10 percent or more and/or a resulting FICO of 620 or less. The loans are then further analyzed to determine if the risk rating should be downgraded which will increase the reserves the Company will establish for potential losses. A report of the semi-annual loan review is published and regularly monitored.
As these loans are revolving lines of credit, the Company, based on the loan agreement and loan covenants of the particular loan, as well as applicable rules and regulations, could suspend the borrowing privileges or reduce the credit limit at any time the Company reasonably believes that the borrower will be unable to fulfill their repayment obligations under the agreement or certain other conditions are met. In many cases, the decrease in FICO is the first indication that the borrower may have difficulty in making their future payment obligations.
As a result, the Company proactively manages the portfolio by performing detailed analysis on its portfolio with emphasis on the NTM portfolio. The Company’s Internal Asset Review Committee (IARC) conducts meetings on at least a quarterly basis to review the loans classified as special mention, substandard, or doubtful and determines whether a suspension or reduction in credit limit is warranted. If the line has been suspended and the borrower would like to have their credit privileges reinstated, they would need to provide updated financials showing their ability to meet their payment obligations.
On the interest only loans, the Company projects future payment changes to determine if there will be a material increase in the required payment and then monitors the loans for possible delinquency. The individual loans are monitored for possible downgrading of risk rating, and trends within the portfolio are identified that could affect other interest only loans scheduled for payment changes in the near future.

The decrease in Green Loans was due to reductions in principal balance and payoffs and the increase in interest only was due to increased originations. During 2014, overall improvement on LTV of the Company’s single family residential NTM first lien portfolio was due to the improvement in the real estate market and the economy in Southern California. The Company updates LTV on a semi-annual basis, typically in the second and fourth quarters or as needed in conjunction with proactive portfolio management.
Allowance for Loan and Lease Losses
The Company has an established credit risk management process that includes regular management review of the loan and lease portfolio to identify problem loans and leases. During the ordinary course of business, management becomes aware of borrowers and lessees that may not be able to meet the contractual requirements of the loan and lease agreements. Such loans and leases are subject to increased monitoring. Consideration is given to placing the loan or lease on non-accrual status, assessing the need for additional allowance for loan and lease losses, and partial or full charge-off. The Company maintains the allowance for loan and lease losses at a level that is considered adequate to cover the estimated and known inherent risks in the loan and lease portfolio.
The Company also maintains a reserve for unfunded loan commitments at a level that is considered adequate to cover the estimated and known inherent risks. The probability of usage of the unfunded loan commitments and credit risk factors determined based on outstanding loan balance of the same customer or outstanding loans that shares similar credit risk exposure are used to determine the adequacy of the reserve. As of December 31, 2014 and 2013, the reserve for unfunded loan commitments was $1.9 million and $1.4 million, respectively.
The credit risk monitoring system is designed to identify impaired and potential problem loans, and to permit periodic evaluation of impairment and the adequacy of the allowance for credit losses in a timely manner. In addition, the Board of Directors of the Bank has adopted a credit policy that includes a credit review and control system which it believes should be effective in ensuring that the Company maintains an adequate allowance for credit losses. The Board of Directors provides oversight and guidance for management’s allowance evaluation process, including quarterly valuations, and consideration of management’s determination of whether the allowance is adequate to absorb losses in the loan and lease portfolio. During year ended December 31, 2014, the Company enhanced the current methodologies, processes and controls over the allowance for loan and lease losses (ALLL), due to the Company's rapid organic and acquisitive growth and rapidly changing profile. See Note 1 for a summary of the enhancements made to the ALLL methodology. The determination of the amount of the allowance for loan and lease losses and the provision for loan and lease losses is based on management’s current judgment about the credit quality of the loan and lease portfolio and takes into consideration known relevant internal and external factors that affect collectability when determining the appropriate level for the allowance for loan and lease losses. Additions to the allowance for loan and lease losses are made by charges to the provision for loan and lease losses. Identified credit exposures that are determined to be uncollectible are charged against the allowance for loan and lease losses. Recoveries of previously charged off amounts, if any, are credited to the allowance for loan and lease losses.

Troubled Debt Restructurings
Troubled Debt Restructurings (TDRs) of loans are defined by ASC 310-40, “Troubled Debt Restructurings by Creditors” and ASC 470-60, “Troubled Debt Restructurings by Debtors” and evaluated for impairment in accordance with ASC 310-10-35. The concessions may be granted in various forms, including reduction in the stated interest rate, reduction in the amount of principal amortization, forgiveness of a portion of a loan balance or accrued interest, or extension of the maturity date. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the Company’s internal underwriting policy.
For the year ended December 31, 2014, there were six modifications through bankruptcy discharges. There were two modifications through extensions of maturities for the year ended December 31, 2013. There were four modifications through extensions of maturities for the year ended December 31, 2012. The following table summarizes the pre-modification and post-modification balances of the new TDRs for the periods indicated:

Credit Quality Indicators
The Company categorizes loans and leases into risk categories 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. The Company performs historical loss analysis that is combined with a comprehensive loan or lease to value analysis to analyze the associated risks in the current loan and lease portfolio. The Company analyzes loans and leases individually by classifying the loans and leases as to credit risk. This analysis includes all loans and leases delinquent over 60 days and non-homogeneous loans and leases such as commercial and commercial real estate loans and leases. Classification of problem single family residential loans is performed on a monthly basis while analysis of non-homogeneous loans and leases is performed on a quarterly basis. The Company uses the following definitions for risk ratings:
Pass: Loans and leases classified as pass are in compliance in all respects with the Bank’s credit policy and regulatory requirements, and do not exhibit any potential or defined weakness as defined under “Special Mention”, “Substandard” or “Doubtful/Loss”.
Special Mention: Loans and leases classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or lease or of the Company’s credit position at some future date.
Substandard: Loans and leases classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans and leases so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.
Doubtful/Loss: Loans and leases classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.
Not-Rated: When accrual of income on a pool of purchased credit impaired (PCI) loans with common risk characteristics is appropriate in accordance with ASC 310-30, individual loans in those pools are not risk-rated. The credit criteria evaluated are FICO scores, loan-to-value, delinquency, and actual cash flows versus expected cash flows of the loan pools.
Loans and leases not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass rated loans and leases.

	The Company retains mortgage servicing rights (MSRs) from certain of its sales of residential mortgage loans. MSRs on residential mortgage loans are reported at fair value. Income earned by the Company on its MSRs is derived primarily from contractually specified mortgage servicing fees and late fees, net of curtailment costs and third party subservicing costs. The Company retains servicing rights in connection with its SBA loan operations, which are measured using the amortization method.
	Income earned from servicing rights was $4.2 million, $2.0 million and $92 thousand for the years ended December 31, 2014, 2013, and 2012, respectively. These amounts are reported in Loan Servicing Income on the Consolidated Statements of Operations. The following table presents a composition of servicing rights as of the dates indicated:

	The goodwill adjustments made during the year ended December 31, 2014 related to the finalization of accounting adjustments for the CS Financial and PBOC acquisitions.
	The Company tests its goodwill for impairment annually as of August 31 (the Measurement Date). At the Measurement Date, the Company, in accordance with ASC 350-20-35-3, evaluated, based on the weight of evidence, the significance of all qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. The assessment of qualitative factors at the Measurement Date indicated that it is not more likely than not that impairment exists; as a result no futher testing was performed.
	Core deposit intangibles are amortized over their useful lives ranging from 4 to 10 years. As of December 31, 2014, the weighted average remaining amortization period for core deposit intangibles was approximately 8.2 years. Customer relationship intangible, related to the RenovationReady acquisition, is amortized over its useful life of 5 years. As of December 31, 2014, the remaining amortization period for customer relationship intangible was approximately 4.1 years. Trade name intangibles, related to the RenovationReady and CS Financial acquisitions, have indefinite useful lives.

	Senior Notes
	On April 23, 2012, the Company completed the public offering of $33.0 million aggregate principal amount of its 7.50 percent Senior Notes due April 15, 2020 (the Senior Notes) at a price to the public of $25.00 per Senior Note. Net proceeds after discounts were approximately $31.7 million. The Senior Notes were issued under the Senior Debt Securities Indenture, dated as of April 23, 2012 (the Base Indenture), as supplemented by the First Supplemental Indenture, dated as of April 23, 2012 (the Supplemental Indenture, and together with the Base Indenture, the Indenture), between the Company and U.S. Bank National Association, as trustee.
	On December 6, 2012, the Company completed the issuance and sale of an additional $45.0 million aggregate principal amount of the Senior Notes at a price to the public of $25.00 per Senior Note, plus accrued interest from October 15, 2012. Net proceeds after discounts, including a full exercise of the $6.8 million underwriters’ overallotment option on December 7, 2012, were approximately $50.1 million.
	The Senior Notes are the Company’s senior unsecured debt obligations and rank equally with all of the Company’s other present and future unsecured unsubordinated obligations. The Senior Notes bear interest at a per-annum rate of 7.50 percent. The Company makes interest payments on the Notes quarterly in arrears.
	The Senior Notes will mature on April 15, 2020. However, the Company may, at the Company’s option, on April 15, 2015, or on any scheduled interest payment date thereafter, redeem the Senior Notes in whole or in part on not less than 30 nor more than 60 days’ prior notice. The Senior Notes will be redeemable at a redemption price equal to 100 percent of the principal amount of the Senior Notes to be redeemed plus accrued and unpaid interest to the date of redemption.
	The Indenture contains several covenants which, among other things, restrict the Company’s ability and the ability of the Company’s subsidiaries to dispose of or incur liens on the voting stock of certain subsidiaries and also contains customary events of default.
	Tangible Equity Units – Amortizing Notes
	On May 21, 2014, the Company issued $69,000,000 of 8.00% tangible equity units (TEUs) in an underwritten public offering. A total of 1,380,000 TEUs were issued, including 180,000 TEUs issued to the underwriter upon exercise of its overallotment option, with each TEU having a stated amount of $50.00. Each TEU is comprised of (i) a prepaid stock purchase contract (each a Purchase Contract) that will be settled by delivery of a specified number of shares of Company Common Stock and (ii) a junior subordinated amortizing note due May 15, 2017 (each an Amortizing Note) that has an initial principal amount of $10.604556 per Amortizing Note, bears interest at a rate of 7.50% per annum and has a scheduled final installment payment date of May 15, 2017. The Company has the right to defer installment payments on the Amortizing Notes at any time and from time to time, subject to certain restrictions, so long as such deferral period does not extend beyond May 15, 2019.
	The Purchase Contracts and Amortizing Notes are accounted for separately. The Purchase Contract component of the TEUs is recorded in Additional Paid in Capital on the Consolidated Statements of Financial Condition. The Amortizing Note is recorded in Notes Payable on the Consolidated Statements of Financial Condition. The relative fair values of the Amortizing Notes and Purchase Contracts were estimated to be approximately $14,634,000 and $54,366,000, respectively. Total issuance costs associated with the TEUs were $4,041,000 (including the underwriter discount of $3,278,000), of which $857,000 was allocated to the liability component and $3,184,000 was allocated to the equity component of the TEUs. The portion of the issuance costs allocated to the debt component of the TEUs is being amortized over the term of the amortizing note. Net proceeds of $64,959,000 from the issuance of the TEUs were designated to partially finance the Company’s previously announced acquisition of 20 California branches from BPNA and for general corporate purposes.

	Net deferred tax assets	$	16,445			$	—			$	7,572
	Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion, or all, of the deferred tax asset will not be realized. In assessing the realization of deferred tax assets, management will continue to evaluate both positive and negative evidence on a quarterly basis, including the existence of any cumulative losses in the current year and the prior two years, the amount of taxes paid in available carry-back years, and tax planning strategies. Based on this analysis, the management determined that it was more likely than not that all of the deferred tax assets would be realized therefore no valuation allowance against net deferred tax assets of $16.4 million was required at December 31, 2014. The Company had recorded a full valuation allowance of $17.3 million against its net deferred tax assets at December 31, 2013.
	The positive evidence supporting the reversal of the Company’s deferred tax asset valuation allowance as of December 31, 2014 included: (i) pretax book income of $25.8 million and estimated taxable income before net operating losses (NOL) of $42.8 million for the year ended December 31, 2014, (ii) four consecutive quarters of positive and accelerating pretax book income from core earnings, (iii) cumulative pretax book income of approximately $27.5 million over the previous 36 month period (without regard to the bargain purchase gain in 2012 related to the Gateway acquisition), (iv) projections of pretax book income for the 2015, 2016 and 2017 years, (v) projection of significant taxable income for the 2015, 2016, and 2017 years, (vi) utilization of $7.9 million and $23.0 million of Federal and State net operating losses (representing approximately 64 percent of the total NOL’s included in the Company’s deferred tax assets) during the year ended December 31, 2014, and (vii) acquisitions which strengthened the Company’s position in primary existing and new markets. Generally, to the extent the Company has book income it will also have taxable income (with the exception of book/tax differences related to the timing of loan charge-offs versus loan loss provisions and the timing of certain mortgage banking gains and losses). Continued profitability from core banking operations through 2014, without significant loan losses, suggests that pretax book income should be sustainable for future years absent a significant increase in loan losses.
	The negative evidence that management considered included: (i) uncertainty in accurately and consistently projecting earnings from operations for tax years ending after December 31, 2014, and (ii) taxable losses generated for the 2012 and 2013 years.
	During 2014, estimated taxable income of $42.8 million allowed the Company to utilize $7.9 million and $23.0 million of Federal and State net operating losses (representing approximately 64 percent of the total NOL’s included in the Company’s deferred tax assets), and all of its $1.7 million of Federal low income housing tax credits. The remaining net operating losses are limited under IRC section 382 and will expire if not used by 2031. In order to utilize all of its existing net operating loss carryover, the Company would only need taxable income of approximately $1.4 million in 2018 and approximately $500 thousand in each year from 2019 to 2031. The Company believes that the utilization of a significant portion of the net operating losses and tax credits in 2014, along with the Company’s projection of future taxable income should be considered significant positive evidence that the net operating loss deferred tax assets will be realized in future periods. Taking all of the foregoing information into account, management believes that it is “more likely than not” that all of the Company’s federal and state net deferred assets will be realized in future years and that, as of December 31, 2014, no valuation allowance against its federal and state deferred tax assets is required.
	The Company adopted the provisions of ASC 740-10-25, which relates to the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements on January 1, 2007. ASC 740-10-25 prescribes a threshold and a measurement process for recognizing in the financial statements a tax position taken or expected to be taken in a tax return and also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.
	At December 31, 2014 and 2013, the Company had $23 thousand and $0 accrued interest or penalties, respectively. The table below summaries the activity related to our unrecognized tax benefits:

Derivative Instruments and Hedging Activities Disclosure [Abstract]
RISK MANAGEMENT AND DERIVATIVE INSTRUMENTS	RISK MANAGEMENT AND DERIVATIVE INSTRUMENTS
	The Company uses derivative instruments and other risk management techniques to reduce its exposure to adverse fluctuations in interest rates in accordance with its risk management policies. The Company utilizes forward contracts and investor commitments to economically hedge mortgage banking products and may from time to time use interest rate swaps as hedges against certain liabilities.
	On September 30, 2013, the Company entered into pay-fixed, receive-variable interest-rate swap contracts with institutional counterparties to hedge against variability in cash flows attributable to interest rate risk caused by changes in the LIBOR benchmark interest rate on the Company’s ongoing LIBOR based variable rate deposits. The Company is accounting for the swaps as cash flow hedges under ASC 815. The notional amount of the interest rate swaps is $50.0 million with a maturity date of September 27, 2018. The fair values of the interest rate swaps were loss of $235 thousand and gain of $226 thousand at December 31, 2014 and 2013, respectively.
	The Company originates residential real estate mortgage loans and generates revenues from the origination and sale of these loans. Although management closely monitors market conditions, such activities are sensitive to fluctuations in prevailing interest rates and real estate markets. As of December 31, 2014, approximately 79.8 percent of all properties securing loans held for sale were located in California. A change in the underlying economic conditions of the California residential real estate market could have an adverse impact on the Company’s results of operations.
	In connection with mortgage banking activities, if interest rates increase, the value of the Company’s loan commitments to borrowers and fixed rate mortgage loans held-for-sale are adversely impacted. The Company attempts to economically hedge the risk of the overall change in the fair value of loan commitments to borrowers and mortgage loans held for sale by selling forward contracts on securities with government-sponsored enterprises (GSEs) and investors in loans. Forward contracts on securities of GSEs and loan commitments to borrowers are non-designated derivative instruments and the gains and losses resulting from these derivative instruments are included in Net Revenue on Mortgage Banking Activities on the Consolidated Statements of Operations. At December 31, 2014, the resulting derivative assets of $6.4 million and liabilities of $3.0 million, are included in Other Assets and Accrued Expenses and Other Liabilities, respectively, on the Consolidated Statements of Financial Condition. At December 31, 2014, the Company had outstanding forward sales commitments totaling $390.6 million. At December 31, 2014, the Company was committed to fund loans for borrowers of approximately $190.0 million.
	The net losses relating to free-standing derivative instruments used for risk management were $17.3 million, $270 thousand and $0 for the years ended December 31, 2014, 2013 and 2012, respectively, and are included in Net Revenue on Mortgage Banking Activities on the Consolidated Statements of Operations.

	Share-based Compensation Expense
	For the years ended December 31, 2014, 2013 and 2012, share-based compensation expense on stock option awards, restricted stock awards and restricted stock units was $6.3 million, $2.9 million, and $1.7 million respectively, and the related tax benefits (expense) were $2.7 million, $0 and $(17) thousand, respectively.
	On July 16, 2013, the Company’s stockholders approved the Company’s 2013 Omnibus Stock Incentive Plan (the 2013 Omnibus Plan). Upon the approval of the 2013 Omnibus Plan, the Company ceased being able to grant new awards under the Company’s 2011 Omnibus Incentive Plan or any prior equity incentive plans. The 2013 Omnibus Plan provides that the aggregate number of shares of Company common stock that may be subject to awards under the 2013 Omnibus Plan will be 20 percent of the then outstanding shares of Company common stock (the Share Limit), provided that in no event will the Share Limit be less than the greater of 2,384,711 shares of Company common stock and the aggregate number of shares of Company common stock with respect to which awards have been properly granted under the 2013 Omnibus Plan up to that point in time. As of December 31, 2014, based on the number of shares then-registered for issuance under the 2013 Omnibus Plan, 540,606 shares were available for future awards under the 2013 Omnibus Plan.
	Unrecognized Share-based Compensation Expense
	The following table presents unrecognized share-based compensation expense as of December 31, 2014:

	Stock Options
	The Company has issued stock options to certain employees, officers and directors. Stock options are issued at the closing market price immediately before the grant date, and generally have a three-to five-year vesting period and contractual terms of seven to ten years.
	The weighted-average estimated fair value per share options granted was estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions.
		Year Ended December 31,
		2014				2013				2012

	Cash received from options exercised	$	993			$	—			$	—
	Weighted-average estimated fair value per share of options granted	$	3.38			$	3.52			$	3.84
	Expected volatility was determined based on the historical monthly volatility of our stock price over a period equal to the expected term of the options granted. The expected term of the options represents the period that options granted are expected to be outstanding based primarily on the historical exercise behavior associated with previous options grants. The risk-free interest rate was based on the U.S. Treasury yield curve at the time of grant for a period equal to the expected term of the options granted.

Stock Appreciation Rights
On August 21, 2012, the Company granted to its chief executive officer a ten-year stock appreciation right (SAR) with respect to 500,000 shares (Initial SAR) of the Company’s common stock with a base price of $12.12 per share. One third of the Initial SAR vested on the grant date, one third vested on the first anniversary of the grant date and one-third vested on the second anniversary of the grant date such that the SAR was fully vested on the second anniversary of the grant date. Upon cessation of the chief executive officer’s service with the Company for “Cause” or without “Good Reason” (including a cessation of service following the expiration of the term of the chief executive officer’s employment agreement), the vested portion of all SARs will expire 90 days following the cessation of service. Except as otherwise described below for the Additional SAR VI, additional SARs (Additional SARs) have been issued to the Company’s chief executive officer with the same terms and conditions (including vesting and dividend equivalent rights) as the Initial SAR pursuant to the anti-dilution provisions under the SAR agreement with the Company due to the Company’s subsequent issuances of shares of common stock.
On May 21, 2014, the Company issued additional SARs (Additional SAR VI) to the Company’s chief executive officer relating to a public offering of the Company’s tangible equity units (TEUs). Each TEU is comprised of a prepaid stock purchase contract (each, a Purchase Contract) and a junior subordinated amortizing note due May 15, 2017 issued by the Company (each, an Amortizing Note). Unless settled early at the holder’s option, each Purchase Contract will automatically settle and the Company will deliver a number of shares of its voting common stock based on the then applicable market value of the voting common stock, ranging from an initial minimum settlement rate of 4.4456 shares per Purchase Contract (subject to adjustment) if the applicable market value is equal to or greater than $11.247 per share to an initial maximum settlement rate of 5.1124 shares per Purchase Contract (subject to adjustment) if the applicable market value is less than or equal to $9.78 per share. The number of settlement shares underlying the Additional SAR VI was calculated using the initial maximum settlement rate and, therefore, the number of shares underlying the Additional SAR VI is subject to adjustment and forfeiture if the aggregate number of shares of stock issued in settlement of any single Purchase Contract is less than the initial maximum settlement rate.
Until each Purchase Contract settles and the voting common stock related thereto is issued, each corresponding Additional SAR VI has a vesting date of May 21, 2017 and has no dividend equivalent rights prior to vesting. The Additional SAR VI vests earlier as follows: (i) for any Purchase Contract settled before August 21, 2014, the Additional SAR VI corresponding to such Purchase Contract became 2/3 vested and exercisable on the date on which any such Purchase Contract was settled and the remaining 1/3 became vested and exercisable on August 21, 2014 and, until it became vested on August 21, 2014, the 1/3 unvested Additional SAR VI corresponding to such Purchase Contract was eligible for the same dividend equivalent rights as the Initial SAR; (ii) for any Purchase Contract settled in shares of voting common stock on or after August 21, 2014, then the Additional SAR VI corresponding to such Purchase Contract shall become 100% vested and exercisable on the date on which any such Purchase Contract is settled; and (iii) if the aggregate number of shares of voting common stock issued in settlement of any single Purchase Contract on the settlement date (the Actually Issued Common Shares) is less than the initial maximum settlement rate, then the Additional SAR VI related to that single Purchase Contract shall be recalculated and adjusted pursuant to the terms of the Initial SAR based on the Actually Issued Common Shares instead of the initial maximum settlement rate and the chief executive officer shall forfeit on such settlement date any Additional SAR VI granted in excess of those that would have been granted on the respective settlement date.
The following table represents a summary of all outstanding SARs (Initial SAR and Additional SARs, together the SARs):
	Initial SAR				Additional				Additional				Additional				Additional			Additional			Additional			Additional

As a result of the settlements of portions of the Purchase Contacts, the Additional SAR VI accelerated in vesting with respect to 133,997 shares and 18,633 shares were forfeited as of December 31, 2014. The portion of Additional SAR VI that has accelerated in vesting has the same terms and conditions as the Initial SAR.
-7	Issued due to the Company's common stock issuance for a private placement completed on November 7, 2014.
The SARs originally were to be settled in cash and the compensation expense for the SARs was recognized over the vesting period based on the fair value as calculated using Black Scholes as of the grant date and adjusted each quarter. On December 13, 2013, the Company amended the Initial SAR agreement to provide that the SARs be settled in shares of voting common stock rather than cash, with all other terms remaining substantially the same. Currently, compensation expense is recognized over the vesting period based on the fair value as calculated using Black Scholes as of the conversion date for the SARs issued before the conversion date and grant dates for the SARs issued after the conversion date.

Compensation and Retirement Disclosure [Abstract]
EMPLOYEE BENEFIT PLANS	EMPLOYEE BENEFIT PLANS
	The Company has a 401(k) plan whereby all employees can participate in the plan. Employees may contribute up to 100 percent of their compensation subject to certain limits based on federal tax laws. The Company makes an enhanced safe-harbor matching contribution that equals to 100 percent of the first 4 percent of the employee’s deferral rate not to exceed 4 percent of the employee’s compensation. The safe-harbor matching contribution is fully vested by the participant when made.
	For the years ended December 31, 2014, 2013 and 2012 expense attributable to 401(k) plans amounted to $2.5 million, $1.7 million and $709 thousand, respectively.
	The Company has adopted a Deferred Compensation Plan under Section 401 of the Internal Revenue Code. The purpose of this plan is to provide specified benefits to a select group of management and highly compensated employees. Participants may elect to defer compensation, which accrues interest quarterly at the prime rate as reflected in The Wall Street Journal as of the last business day of the prior quarter. The Company does not make contributions to the Plan.
	Employee Equity Ownership Plan
	The Company established the Employee Equity Ownership Plan (EEOP) effective October 15, 2013 for the benefit of employees. The EEOP is administered under the Company’s 2013 Omnibus Stock Incentive Plan and the awards thereunder are issued upon the terms and conditions and subject to the restrictions of the Company’s 2013 Omnibus Stock Incentive Plan. The EEOP provides that employees eligible to receive awards under the EEOP are any employees with titles below Assistant Vice President or any employees who are not otherwise given shares pursuant to any other Company-sponsored equity program. The Company issued 324,540 shares of restricted stock awards and units under the EEOP.
	Employee Stock Ownership Plan
	The Company maintained the Employee Stock Ownership Plan (ESOP) for the benefit of its employees. The Company issued 423,200 shares of common stock to the ESOP in exchange for a ten-year note in the amount of approximately $5.1 million. The $5.1 million for the ESOP purchase was borrowed from the Company. The ESOP was terminated effective December 2011 and was completely distributed in October 2013. The ten-year note was paid in full at December 31, 2011.
	Shares issued to the ESOP were allocated to ESOP participants based on principal repayments made by the ESOP on the loan from the Company. The loan was secured by shares purchased with the loan proceeds and was repaid by the ESOP with funds from the Company’s contributions to the ESOP and earnings on ESOP assets. Principal payments were scheduled to occur over a ten-year period. Dividends on allocated and/or unearned shares first reduced accrued interest and secondly principal.
	During 2011 and 2010, 42,320 shares of stock with an average fair value of $14.29 and $10.75 per share were committed to be released, resulting in ESOP compensation expense of $605 thousand and $455 thousand, respectively, for each year. As of December 31, 2012, the remaining shares committed to be released were fully allocated to participants. There was no ESOP compensation expense recorded during 2012. During 2011 and 2010, 1,861, and 144 shares were forfeited, respectively. There were no shares forfeited during 2012. Per the terms of the ESOP plan, the forfeited shares were sold out of the plan and the proceeds were used to reduce the Company’s contribution resulting in a reduction of compensation expense. The ESOP was completely liquidated in October 2013.

	Warrants
	On November 1, 2010, the Company issued warrants to TCW Shared Opportunity Fund V, L.P. for up to 240,000 shares of non-voting common stock at an original exercise price of $11.00 per share, subject to certain adjustments to the number of shares underlying the warrants as well as certain adjustments to the warrant exercise price as applicable. These warrants are exercisable from the date of original issuance through November 1, 2015.
	On November 1, 2010, the Company also issued warrants to COR Advisors LLC, an entity controlled by Steven A. Sugarman, who became a director of the Company on that date and later became President and Chief Executive Officer of the Company, to purchase up to 1,395,000 shares of non-voting common stock at an exercise price of $11.00 per share, subject to certain adjustments to the number of shares underlying the warrants as well as certain adjustments to the warrant exercise price as applicable. As a result of transfers of these warrants subsequent to their original issuance, warrants for the right to purchase 960,000 shares of non-voting common stock are now held by Mr. Sugarman and his spouse through a living trust, and warrants for the right to purchase 435,000 shares of non-voting common stock are now held by Jeffrey T. Seabold, Executive Vice President and Chief Lending Officer of the Bank. These warrants vested in tranches, with the first tranche vesting on January 1, 2011 and the last tranche vesting on July 1, 2013 and with each respective tranche being exercisable for five years after the tranche's vesting date.
	The warrants are exercisable for voting common stock in lieu of non-voting common stock following the transfer of the warrants in a widely dispersed offering or in other limited circumstances. Based on automatic adjustments to the original $11.00 exercise price, the Company has determined that the exercise price for these warrants was $9.32 per share as of December 31, 2014. The terms and issuance of the foregoing warrants were approved by the Company's stockholders at a special meeting held on October 25, 2010.

	On May 21, 2014, the Company issued 5,150,000 shares of its voting common stock in an underwritten public offering and for gross proceeds of approximately $50.4 million and 772,500 shares of voting common stock upon the exercise in full by the underwriters of the underwritten public offering of their 30-day over-allotment option, for additional gross proceeds of approximately $7.6 million.
	On November 7, 2014, the Company completed the issuance and sale of 3,288,947 shares of its voting common stock to OCM BOCA Investor, LLC (Oaktree), an entity owned by investment funds managed by Oaktree Capital Management, L.P., and 1,900,000 shares of its voting common stock to Patriot Financial Partners, L.P., Patriot Financial Partners Parallel, L.P., Patriot Financial Partners II, L.P. and Patriot Financial Partners Parallel II, L.P, for gross proceeds of $49.9 million.
	Perpetual Preferred Stock
	On June 12, 2013, in an underwritten public offering, the Company sold 1,400,000 depositary shares, each representing a 1/40th interest in a share of its 8.00 percent Non-Cumulative Perpetual Preferred Stock, Series C, par value $0.01 per share and liquidation preference of $1,000 per share, at an offering price of $25.00 per depositary share, for gross proceeds of $33.9 million. The Company also granted the underwriters a 30-day option to purchase up to an additional 210,000 depositary shares to cover over-allotments, if any, at the same price, for potential additional gross proceeds of $5.1 million, which the underwriters exercised in full on July 8, 2013.
	As discussed under Note 2, on July 1, 2013, the Company completed its previously announced acquisition of PBOC. Upon completion of the acquisition, each share of preferred stock issued by PBOC as part of the Small Business Lending Fund (SBLF) program of the United States Department of Treasury (10,000 shares in the aggregate with a liquidation preference amount of $1,000 per share) was converted automatically into one substantially identical share of preferred stock of the Company with a liquidation preference amount of $1,000 per share, designated as the Company’s Non-Cumulative Perpetual Preferred Stock, Series B. The terms of the preferred stock issued by the Company in exchange for the PBOC preferred stock are substantially identical to the preferred stock previously issued by the Company as part of its own participation in the SBLF program (32,000 shares in aggregate with a liquidation preference amount of $1,000 per share), designated as the Company’s Non-Cumulative Perpetual Preferred Stock, Series A.
	Tangible Equity Units
	On May 21, 2014, the Company completed an underwritten public offering of 1,380,000 of its tangible equity units (TEUs), which included 180,000 TEUs issued to the underwriter upon the full exercise of its over-allotment option, resulting in net proceeds of $65.0 million. Each TEU is comprised of a prepaid stock purchase contract (each, a Purchase Contract) and a junior subordinated amortizing note due May 15, 2017 issued by the Company (each, an Amortizing Note). Unless settled early at the holder’s option, each Purchase Contract will automatically settle and the Company will deliver a number of shares of its voting common stock based on the then-applicable market value of the voting common stock, ranging from an initial minimum settlement rate of 4.4456 shares per Purchase Contract (subject to adjustment) if the applicable market value is equal to or greater than $11.247 per share to an initial maximum settlement rate of 5.1124 shares per Purchase Contract (subject to adjustment) if the applicable market value is less than or equal to $9.78 per share.
	From the first business day following the issuance of the TEUs to but excluding the third business day immediately preceding May 15, 2017, a holder of a Purchase Contract may settle its Purchase Contract early, and the Company will deliver to the holder 4.4456 shares of voting common stock. The holder also may elect to settle its Purchase Contract early in connection with a “fundamental change,” in which case the holder will receive a number of shares of voting common stock based on a fundamental change early settlement rate. The Company may elect to settle all Purchase Contracts early by delivering to each holder 5.1124 shares of voting common stock or, under certain circumstances, by delivering 4.4456 shares of voting common stock. As of December 31, 2014, a total of 656,692 Purchase Contracts had been settled early by their holders, resulting in the issuance by the Company of 2,919,390 shares of voting common stock. As of December 31, 2014, 723,308 Purchase Contracts remained outstanding.
	Each Amortizing Note has an initial principal amount of $10.604556 per Amortizing Note, bears interest at a rate of 7.50% per annum and has a scheduled final installment payment date of May 15, 2017. On each August 15, November 15, February 15 and May 15, commencing on August 15, 2014, the Company will pay holders of Amortizing Notes equal quarterly cash installments of $1.00 per Amortizing Note (or, in the case of the installment payment due on August 15, 2014, $0.933333 per Amortizing Note) (such installments, the installment payments), which installment payments in the aggregate will be equivalent to a 8.00% cash distribution per year with respect to each $50.00 stated amount of TEUs. Each installment payment will constitute a payment of interest (at a rate of 7.50% per annum) and a partial repayment of principal on each Amortizing Note. The Company has the right to defer installment payments at any time and from time to time, subject to certain restrictions, so long as such deferral period does not extend beyond May 15, 2019. If the Company elects to settle the Purchase Contracts early, the holders of the Amortizing Notes will have the right to require the Company to repurchase the Amortizing Notes. As of December 31, 2014, the Amortizing Notes totaled $12.0 million, net of unamortized discounts, and were included in Notes Payable on the Consolidated Statements of Financial Condition.

REGULATORY CAPITAL MATTERS	REGULATORY CAPITAL MATTERS
	The Company and the Bank are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. Management believes as of December 31, 2014, the Company and the Bank met all capital adequacy requirements to which they were then subject. With respect to the Bank, prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If only adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. At December 31, 2014, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the institution’s category.

	Through December 31, 2014, the FRB required bank holding companies such as the Company to maintain a minimum ratio of qualifying total capital to risk-weighted assets of 8.0 percent and a minimum ratio of Tier 1 capital to risk-weighted assets of 4.0 percent. In addition to the risk-based guidelines, through December 31, 2014 the FRB required bank holding companies to maintain a minimum ratio of Tier 1 capital to average total assets, referred to as the leverage ratio, of 4.0 percent. Through December 31, 2014, in order to be considered “well capitalized,” federal bank regulatory agencies required depository institutions such as the Bank to maintain a minimum ratio of qualifying total capital to risk-weighted assets of 10.0 percent, a minimum ratio of Tier 1 capital to risk-weighted assets of 6.0 percent and a minimum ratio of Tier 1 capital to average total assets, referred to as the leverage ratio, of 5.0 percent.
	In July 2013, the Federal banking regulators approved a final rule to implement the revised capital adequacy standards of the Basel Committee on Banking Supervision, commonly called Basel III, and to address relevant provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the Dodd-Frank Act). The final rule strengthens the definition of regulatory capital, increases risk-based capital requirements, makes selected changes to the calculation of risk-weighted assets, and adjusts the prompt corrective action thresholds. The Company and the Bank became subject to the new rule on January 1, 2015 and certain provisions of the new rule will be phased in over the period of 2015 through 2019.
	The final rule:
	•	Permits banking organizations that had less than $15 billion in total consolidated assets as of December 31, 2009, to include in Tier 1 capital trust preferred securities and cumulative perpetual preferred stock that were issued and included in Tier 1 capital prior to May 19, 2010, subject to a limit of 25 percent of Tier 1 capital elements, excluding any non-qualifying capital instruments and after all regulatory capital deductions and adjustments have been applied to Tier 1 capital.
	•	Establishes new qualifying criteria for regulatory capital, including new limitations on the inclusion of deferred tax assets and mortgage servicing rights.
	•	Requires a minimum ratio of common equity Tier 1 capital to risk-weighted assets of 4.5 percent.
	•	Increases the minimum Tier 1 capital to risk-weighted assets ratio requirement from 4 percent to 6 percent.
	•	Retains the minimum total capital to risk-weighted assets ratio requirement of 8 percent.
	•	Establishes a minimum leverage ratio requirement of 4 percent.
	•	Changes the prompt corrective action standards so that in order to be considered well-capitalized, a depository institution must have a ratio of common equity Tier 1 capital to risk-weighted assets of 6.5 percent (new), a ratio of Tier 1 capital to risk-weighted assets of 8 percent (increased from 6 percent), a ratio of total capital to risk-weighted assets of 10 percent (unchanged), and a leverage ratio of 5 percent (unchanged).
	•	Retains the existing regulatory capital framework for one-to-four family residential mortgage exposures.
	•	Permits banking organizations that are not subject to the advanced approaches rule, such as the Company and the Bank, to retain, through a one-time election, the existing treatment for most accumulated other comprehensive income, such that unrealized gains and losses on securities available for sale will not affect regulatory capital amounts and ratios.
	•	Implements a new capital conservation buffer requirement for a banking organization to maintain a common equity capital ratio more than 2.5 percent above the minimum common equity Tier 1 capital, Tier 1 capital and total risk-based capital ratios in order to avoid limitations on capital distributions, including dividend payments, and certain discretionary bonus payments. The capital conservation buffer requirement will be phased in beginning on January 1, 2016 at 0.625 percent and will be fully phased in at 2.50 percent by January 1, 2019. A banking organization with a buffer of less than the required amount would be subject to increasingly stringent limitations on such distributions and payments as the buffer approaches zero. The new rule also generally prohibits a banking organization from making such distributions or payments during any quarter if its eligible retained income is negative and its capital conservation buffer ratio was 2.5 percent or less at the end of the previous quarter. The eligible retained income of a banking organization is defined as its net income for the four calendar quarters preceding the current calendar quarter, based on the organization’s quarterly regulatory reports, net of any distributions and associated tax effects not already reflected in net income.
	•	Increases capital requirements for past-due loans, high volatility commercial real estate exposures, and certain short-term commitments and securitization exposures.
	•	Expands the recognition of collateral and guarantors in determining risk-weighted assets.
	•	Removes references to credit ratings consistent with the Dodd Frank Act and establishes due diligence requirements for securitization exposures.
	Dividend Restrictions
	The Company’s principal source of funds for dividend payments is dividends received from the Bank. Federal banking laws and regulations limit the amount of dividends that may be paid without prior approval of regulatory agencies. Under these regulations, in the case of the Bank, the amount of dividends that may be paid in any calendar year is limited to the current year’s net profits, combined with the retained net profits of the preceding two years, subject to the capital requirements described above. For the year of 2014, the Bank had $36.1 million plus any net profits generated in 2014 available to pay dividends to the Company.

Earnings Per Share [Abstract]
EARNINGS PER COMMON SHARE	EARNINGS PER COMMON SHARE
	Net income (loss) allocated to common stockholders is computed by subtracting income allocated to participating securities, participating securities dividends and preferred stock dividend from net income. Participating securities are instruments granted in share-based payment transactions that contain rights to receive nonforfeitable dividends or dividend equivalents, which includes the SARs as they confer dividend equivalent rights, as described under “Stock Appreciation Rights” in Note 16. Basic earnings (loss) per common share (EPS) is computed by dividing net income allocated to common stockholders by the weighted average number of shares outstanding, including the minimum number of shares issuable under purchase contracts relating to the tangible equity units. Diluted EPS is computed by dividing net income (loss) allocated to common stockholders by the weighted average number of shares outstanding, adjusted for the dilutive effect of the restricted stock units, the potentially issuable shares in excess of the minimum under purchase contracts relating to the tangible equity units, outstanding stock options, and warrants to purchase common stock.

LOAN COMMITMENTS AND OTHER RELATED ACTIVITIES	LOAN COMMITMENTS AND OTHER RELATED ACTIVITIES
	Some financial instruments such as loan commitments, credit lines, letters of credit, and overdraft protection are issued to meet customer financing needs. These are agreements to provide credit or to support the credit of others, as long as conditions established in the contract are met, and usually have expiration dates. Commitments may expire without being used. Risk of credit loss exists up to the face amount of these instruments. The same credit policies are used to make such commitments as are used for loans, including obtaining collateral at exercise of the commitment.
	The contractual amount of financial instruments with off-balance-sheet risk was as follows for the dates indicated:

These commitments consisted of jumbo mortgage loan sale commitments of $54.2 million, TBAs of $328.0 million, best efforts of $40.0 million, and other commitments of $0. Additionally, the Company had IRLCs of $190.0 million at December 31, 2014.
	Litigation
	In the normal course of business, we are involved in various legal claims. Management has reviewed all pending legal claims against us with in-house or outside legal counsel and has taken into consideration the views of such counsel as to the outcome of the claims.

Segment Reporting [Abstract]
SEGMENT REPORTING	SEGMENT REPORTING
	The Company utilizes an internal reporting system to measure the performance of various operating segments within the Bank and the Company overall. The Company has identified four operating segments for purposes of management reporting: 1) Banking; 2) Mortgage Banking; 3) Financial Advisory and Asset Management; and 4) Corporate/Other. These four business divisions meet the criteria of an operating segment. the segment engages in business activities from which it earns revenues and incurs expenses and whose operating results are regularly reviewed by the Company’s chief operating decision-maker, the Company's President and Chief Executive Officer or his delegate, to make decisions about resources to be allocated to the segment and assess its performance and for which discrete financial information is available.
	The principal business of the Banking segment consists of attracting deposits and investing these funds primarily in commercial, consumer and real estate secured loans. The principal business of the Mortgage Banking segment is originating conforming SFR loans and selling these loans in the secondary market. Financial Advisory and Asset Management segment is operated by The Palisades Group and provides services of purchase, sale and management of SFR mortgage loans. The Corporate/Other segment includes the holding company and PTB, an entity formed to hold real estate. The Corporate/Other operating segment engages in business activities through the sale of other real estate owned and loans held at the holding company and incurs interest expense on debt as well as non-interest expense for corporate related activities. The operating segment results do not include allocation of centralized costs that are currently recorded in the Banking and Corporate/Other segment. The Company is currently in the process of determining the basis for calculating allocations.
	The prior periods’ measurement of operating segment performance may be restated for comparability for changes in the Company’s management structure or reporting methodologies unless it is not deemed practicable to do so. The following table represents the operating segments’ financial results and other key financial measures as of or for the years ended December 31, 2014, 2013, and 2012:

Related Party Transactions [Abstract]
RELATED-PARTY TRANSACTIONS	RELATED-PARTY TRANSACTIONS
	The Bank has granted loans to certain officers and directors and their related interests. Loans outstanding to officers and directors and their related interests amounted to $200 thousand and $748 thousand at December 31, 2014 and 2013, respectively, each of which were performing in accordance with their respective terms. These loans are made in the ordinary course of business and on substantially the same terms and conditions, including interest rates and collateral, as those of comparable transactions with non-insiders prevailing at the time, in accordance with the Bank’s underwriting guidelines, and do not involve more than the normal risk of collectability or present other unfavorable features. The Bank has an Employee Loan Program (the Program) which offers executive officers, directors and principal stockholders that meet the eligibility requirements the opportunity to participate on the same terms as employees generally, provided that any loan to an executive officer, director or principal stockholder must be approved by the Bank’s Board of Directors. The sole benefit provided under the Program is a reduction in loan fees.
	Deposits from principal officers, directors, and their related interests amounted to $4.5 million and $10.5 million at December 31, 2014 and 2013, respectively.
	Transactions Involving Steven A. Sugarman. The following is a description of transactions involving the Company and certain entities affiliated with or relatives of Steven A.

	The Palisades Group Lease Payment Reimbursements. The Company acquired its subsidiary, The Palisades Group, LLC (The Palisades Group) on September 10, 2013, at which time Palisades occupied premises in Santa Monica, California leased by COR Securities Holding, Inc. (CORSHI), of which Mr. Sugarman is the Chief Executive Officer as well as a stockholder (both directly and indirectly). In light of the benefit received by The Palisades Group of its occupancy of the Santa Monica premises, the non-interested directors of the Company’s Board ratified reimbursement to CORSHI for rental payments made for the Santa Monica premises for the period commencing September 16, 2013 through the last date The Palisades Group occupies the premises. The Palisades Group negotiated with an unaffiliated third party a lease for new premises and occupied those premises on June 27, 2014. On the same date, The Palisades Group vacated the Santa Monica CORSHI premises.
	The aggregate rent payments reimbursed to CORSHI from September 16, 2013 through December 30, 2013 were $39,972 comprised of: (i) $5,661, the pro-rated base rent amount for the partial month of September 2013; (ii) $11,324 per month in base rent for the months of October and November 2013; and (iii) $11,663 per month in base rent for the month of December 2013.
	Regarding the security deposit for the premises, after The Palisades Group occupied the CORSHI premises, the Company reimbursed CORSHI relating to a security deposit amount for the premises of $33,844. The Company received reimbursement of this security deposit amount from The Palisades Group. For the months of January 1, 2014 through June 27, 2014, CORSHI granted The Palisades Group a rent abatement equal to the $33,844 security deposit and combined with additional payments, The Palisades Group paid leasing costs totaling $57,616 to CORSHI for that same time period. The Board’s Compensation, Nominating and Corporate Governance Committees have monitored all the reimbursement costs reviewed the aggregate reimbursement costs.
	The Palisades Group Consulting Agreement. As discussed above, the Company acquired its subsidiary, The Palisades Group, on September 16, 2013.

The consulting agreement is for a term of 5 years, with a minimum payment of $30,000 owed at the end of each quarter for consulting services Jason Sugarman has provided The Palisades Group. There is also the potential for additional bonus payments based on the nature of work performed and the financial results of The Palisades Group. The aggregate amount of identified payments that will be paid by The Palisades Group to Jason Sugarman under the five-year term of the consulting agreement will exceed $600,000 as that is the minimum amount owed under the agreement, but does not include any bonuses that may be earned under the agreement. For the year ended December 31, 2013 and the year ended December 31, 2014, base and bonus amounts earned by Jason Sugarman under the consulting agreement totaled $120,662 and $1,240,000, respectively.

Based on a Schedule 13-G amendment filed with the Securities and Exchange Commission on February 14, 2012, St. Cloud Capital, LLC (St. Cloud) holds 700,538 shares of the Company’s Voting Common Stock. On November 24, 2014, the Bank invested as a limited partner in an affiliate of St. Cloud.

The Community Reinvestment Act of 1977 expressly identifies an investment by a bank in an SBIC as a type of investment that is presumed by the regulatory agencies to promote economic development.
	The Boards of Directors of the Company and the Bank approved the Bank’s investment. The Bank has agreed to invest a minimum of $5 million, but up to $7.5 million as long as the Bank’s limited partnership interest in the Partnership remains under 9.9 percent.

	CS Financial Services Agreement. On December 27, 2012, the Company entered into a Management Services Agreement (Services Agreement) with CS Financial. On December 27, 2012, Mr. Seabold was then a member of the Board of Directors of each of the Company and the Bank. Under the Services Agreement, CS Financial agreed to provide the Bank such reasonably requested financial analysis, management consulting, knowledge sharing, training services and general advisory services as the Bank and CS Financial mutually agreed upon with respect to the Bank’s residential mortgage lending business, including strategic plans and business objectives, compliance function, monitoring, reporting and related systems, and policies and procedures, at a monthly fee of $100,000. The Services Agreement was recommended by disinterested members of management of the Bank and negotiated and approved by special committees of the Board of Directors of each of the Company and the Bank (Special Committees), comprised exclusively of independent, disinterested directors of the Boards. Each of the Boards of Directors of the Bank and the Company also considered and approved the Services Agreement, upon the recommendation of the Special Committees.
	On May 13, 2013, the Bank hired Mr. Seabold as Managing Director and Chief Lending Officer by entering into a three-year employment agreement with Mr. Seabold (the Employment Agreement). Simultaneously, the Bank terminated, with immediate effect, its Services Agreement with CS Financial. For the year ended December 31, 2013, the total compensation paid to CS Financial under the Services Agreement was $439,000.
	Option to Acquire CS Financial. Under the Employment Agreement, Mr. Seabold granted to the Company and the Bank an option (CS Call Option), to acquire CS Financial for a purchase price of $10 million, payable pursuant to the terms provided under the Employment Agreement. Based upon the recommendation of the Special Committees, with the assistance of outside financial and legal advisors and consultants, the Boards of Directors of the Company and the Bank, with Mr. Sugarman recusing himself from the discussions and vote due to previously disclosed conflicts of interest, approved the recommendation of the Special Committees and, pursuant to a letter dated July 29, 2013, the Company indicated that the CS Call Option was being exercised by the Bank, subject to the negotiation and execution of definitive transaction documentation consistent with the applicable provisions of the Employment Agreement and the satisfaction of the terms and conditions set forth therein.
	Merger Agreement. After exercise of the CS Call Option as described above, the Company and the Bank entered into an Agreement and Plan of Merger (Merger Agreement) with CS Financial, the stockholders of CS Financial (Sellers) and Mr. Seabold, as the Sellers’ Representative, and completed its acquisition of CS Financial on October 31, 2013.
	Subject to the terms and conditions set forth in the Merger Agreement, which was approved by the Board of Directors of each of the Company, the Bank and CS Financial, at the effective time of the Merger, the outstanding shares of common stock of CS Financial were converted into the right to receive in the aggregate: (1) upon the closing of the Merger, (a) 173,791 shares (Closing Date Shares) of voting common stock, par value $0.01 per share, of the Company (Voting Common Stock), and (b) $1,500,000 in cash and $3,150,000 in the form of a noninterest-bearing note issued by the Company to Mr. Seabold that was due and paid by the Company on January 2, 2014; and (2) upon the achievement of certain performance targets by the Bank’s lending activities following the closing of the Merger that are set forth in the Merger Agreement, up to 92,781 shares (Performance Shares) of Voting Common Stock ((1) and (2), together, Merger Consideration).

Mr. Sugarman abstained from the vote of each of the Boards of Directors of the Company and the Bank to approve the Merger Agreement and the Merger.
	Transaction Involving Halle Benett. On May 21, 2014, the Company issued 5,150,000 shares of its Voting Common Stock in an underwritten public offering and 772,500 shares of Voting Common Stock upon the exercise in full by the underwriters of the underwritten public offering of their 30-day over-allotment option. Halle Benett, a director of the Company and the Bank, became employed on April 1, 2014 as a Managing Director and Co-head of the Diversified Financials Group at Keefe, Bruyette & Woods, Inc., a Stifel company. Mr. Benett, who became a director of the Bank on January 28, 2014, was elected to the Board of Directors of the Company on May 15, 2014. On May 15, 2014, the Company entered into an underwriting agreement pursuant to which Keefe, Bruyette & Woods, Inc., acted as one of the underwriters of the public offering and received gross underwriting fees and commissions from the Company of approximately $520,644 for its services as an underwriter (less expenses, the amount was $481,166).
	Transaction Involving Former Chairman Timothy R. Chrisman. On May 15, 2014, the disinterested members of the Board of Directors of the Company approved a strategic advisor agreement with Chrisman & Co. pursuant to which Chrisman & Co. would provide strategic advisory services for the Company. Mr. Chrisman, who retired from the Company Board on May 15, 2014 upon the expiration of the term of his directorship after the Company’s 2014 Annual Meeting of Stockholders, is the Chief Executive Officer and founding principal of Chrisman & Co. The initial term of the strategic advisor agreement is for a period of one year and, thereafter, the agreement may be extended on a month-to-month basis.

	Transactions with Greater Than 5 Percent Stockholders Who are Not Executive Officers
	Exchange Agreement with TCW Shared Opportunity Fund V, L.P. and its Assignees. TCW Shared Opportunity Fund V, L.P. (SHOP V Fund), an affiliate of The TCW Group, Inc., initially became a holder of the Company’s Voting Common Stock and non-voting common stock (Non-Voting Common Stock) as a lead investor in the November 2010 recapitalization of the Company (the Recapitalization). In connection with its investment in the Recapitalization, SHOP V Fund also was issued by the Company an immediately exercisable five-year warrant (the SHOP V Fund Warrant) to purchase 240,000 shares of Non-Voting Common Stock or, to the extent provided therein, shares of Voting Common Stock in lieu of Non-Voting Common Stock. SHOP V Fund was issued shares of Non-Voting Common Stock in the Recapitalization because at that time, a controlling interest in TCW Asset Management Company, the investment manager to SHOP V Fund, was held by a foreign banking organization, and in order to prevent SHOP V Fund from being considered a bank holding company under the Bank Holding Company Act of 1956, as amended, the number of shares of Voting Common Stock it purchased in the Recapitalization had to be limited to 4.99 percent of the total number of shares of Voting Common Stock outstanding immediately following the Recapitalization. For the same reason, the SHOP V Fund Warrant could be exercised by SHOP V Fund for Voting Common Stock in lieu of Non-Voting Common Stock only to the extent SHOP V Fund’s percentage ownership of the Voting Common Stock at the time of exercise would be less than 4.99 percent as a result of dilution occurring from additional issuances of Voting Common Stock subsequent to the Recapitalization.
	In 2013, the foreign banking organization sold its controlling interest in TCW Asset Management Company, eliminating the need to limit SHOP V Fund’s percentage ownership of the Voting Common Stock to 4.99 percent. As a result, on May 29, 2013, the Company and SHOP V Fund entered into a Common Stock Share Exchange Agreement, dated May 29, 2013 (Exchange Agreement), pursuant to which SHOP V Fund may from time to time exchange its shares of Non-Voting Common Stock for shares of Voting Common Stock issued by the Company on a share-for-share basis, provided that immediately following any such exchange, SHOP V Fund’s percentage ownership of Voting Common Stock does not exceed 9.99 percent. The shares of Non-Voting Common Stock that may be exchanged by SHOP V Fund pursuant to the Exchange Agreement include the shares of Non-Voting Common Stock it purchased in the Recapitalization, the additional shares of Non-Voting Common Stock SHOP V Fund acquired subsequent to the Recapitalization (and may in the future acquire) pursuant to the Company’s Dividend Reinvestment Plan and any additional shares of Non-Voting Common Stock that SHOP V Fund acquires pursuant to its exercise of the SHOP V Fund Warrant.
	On December 10, 2014, SHOP V Fund and two affiliated entities, Crescent Special Situations Fund Legacy V, L.P. (CSSF Legacy V) and Crescent Special Situations Fund Investor Group, L.P. (CSSF Investor Group), entered into a Contribution, Distribution and Sale Agreement pursuant to which SHOP V Fund agreed to transfer shares of Non-Voting Common Stock and portions of the SHOP V Fund Warrant to CSSF Legacy V and CSSF Investor Group. Also on December 10, 2014, SHOP V Fund, CSSF Legacy V, CSSF Investor Group and the Company entered into an Assignment and Assumption Agreement pursuant to which all of SHOP V Fund’s rights and obligations under the Exchange Agreement with respect to the shares of Non-Voting Common Stock transferred by it to CSSF Legacy V and CSSF Investor Group pursuant to the Contribution, Distribution and Sale Agreement were assigned to CSSF Legacy V and CSSF Investor Group, including the right of SHOP V Fund to exchange such shares for shares of Voting Common Stock on a one-for-one basis.
	On June 3, 2013, January 5, 2015, and January 20, 2015, SHOP V Fund or CSSF Legacy V or CSSF Investor Group exchanged 550,000 shares, 522,564 shares and 86,620 shares, respectively, of Non-Voting Common Stock for the same number of shares of Voting Common Stock. As a result of these exchanges, the Company believes that as of February 27, 2015 The TCW Group, Inc. and its affiliates held 1,687,646 shares of Voting Common Stock and 934 shares of Non-Voting Common Stock, plus the SHOP V Fund Warrant under which up to 240,000 shares of Non-Voting Common Stock may be issued upon exercise and may thereafter be exchanged for shares of Voting Common Stock pursuant to the Exchange Agreement.
	Securities Purchase Agreement with Patriot Financial Partners, L.P. and Patriot Financial Partners Parallel, L.P. As reported in a Schedule 13-D amendment filed on November 10, 2014 with the SEC, Patriot Financial Partners, L.P and Patriot Financial Partners Parallel, L.P. (Patriot) hold 3,100,564 shares of the Company’s Voting Common Stock. As previously disclosed, on April 22, 2014, the Company entered into a Securities Purchase Agreement (SPA) with Patriot to raise a portion of the capital to be used to finance the previously announced acquisition of select assets and assumption of certain liabilities comprising BPNA’S network of 20 California branches by the Bank. The SPA with Patriot was due to expire by its terms at the end of the day on October 31, 2014. Prior to such expiration, the Company and Patriot Financial Partners, L.P., Patriot Financial Partners Parallel, L.P., Patriot Financial Partners II, L.P. and Patriot Financial Partners Parallel II, L.P. (together referred to as Patriot Partners) entered into a Securities Purchase Agreement, dated as of October 30, 2014 (New SPA). Pursuant to the New SPA, concurrently with the Bank's BPNA Branch Acquisition, which closed on November 8, 2014, Patriot Partners simultaneously purchased from the Company (i) 1,076,000 shares of its voting common stock at a price of $9.78 per share and (ii) 824,000 shares of its voting common stock at a price of $11.55 per share, for an aggregate purchase price of $20,040,480. In consideration for Patriot’s commitment under the New SPA and pursuant the terms of the New SPA, on that same date concurrently with the closing of the sale of shares, the Company paid Patriot an equity support payment of $538,000 and also reimbursed Patriot $100,000 in out-of-pocket expenses.
	Agreement with Oaktree Capital Management. As reported in a Schedule 13-G filed with the SEC on January 16, 2015, OCM BOCA Investor, LLC (OCM), an affiliate of Oaktree Capital Management, L.P., owns 3,288,947 shares of the Company’s Voting Common Stock. OCM purchased these 3,288,947 shares of Voting Common Stock (representing 9.9 percent of total shares outstanding as of the dates set forth in the Schedule 13-G) from the Company on November 7, 2014 at a price of $9.78 per share pursuant to a securities purchase agreement entered into on April 22, 2014 (and amended on October 28, 2014) to raise a portion of the capital needed for the BPNA Branch Acquisition, which was completed on November 8, 2014. In consideration for its commitment under the securities purchase agreement, OCM was paid at closing an equity support payment from the Company of $1.6 million.
	Before OCM became a stockholder, The Palisades Group, and certain affiliates of Oaktree Capital Management, L.P. (collectively, the Oaktree Funds), entered into a management agreement, effective as of January 30, 2014 (Management Agreement), pursuant to which The Palisades Group serves as the credit manager of pools of single family residential mortgage loans held in securitization trusts or other vehicles beneficially owned by the Oaktree Funds. The Palisades Group is paid a monthly management fee primarily based on the amount of certain designated pool assets and may earn additional fees for advice related to financing opportunities. Payments under the Management Agreement to The Palisades Group during 2014 totaled $5.3 million, which in some instances represents fees for partial year services. In addition, in the future and from time to time we may enter into lending transactions with portfolio companies of investment funds managed by Oaktree Capital Management, L.P.

SUMMARY_OF_SIGNIFICANT_ACCOUNT1

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The consolidated financial statements include the accounts of the Company and all other entities in which it has a controlling financial interest. All significant intercompany accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its wholly owned subsidiaries. The accounting and reporting polices of the Company are based upon U.S. generally accepted accounting principles (GAAP) and conform to predominant practices within the financial services industry. Significant accounting policies followed by the Company are presented below.
	Certain prior period amounts have been reclassified to conform to the current year's presentation. These reclassifications had no impact on the Company's consolidated financial position, results of operations or net change in cash or cash equivalents.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and disclosures provided, and actual results could differ. The allowance for loan and lease losses, reserve for loss on repurchased loans, servicing rights, realization of deferred tax assets, the valuation of goodwill and other intangible assets, mortgage banking derivatives, purchased credit impaired loan discount accretion, fair value of assets and liabilities acquired in business combinations, and the fair value measurement of financial instruments are particularly subject to change and such change could have a material effect on the consolidated financial statements.
Cash and cash equivalents	Cash and cash equivalents: Cash and cash equivalents include cash on hand, interest-bearing deposits with other financial institutions with original maturities under 90 days, and daily federal funds sold. Net cash flows are reported for customer loan and deposit transactions, interest bearing deposits in other financial institutions, and federal funds purchased, including overnight borrowings with the Federal Home Loan Bank.
	Cash flows from loans, either originated or acquired, are classified at that time according to management's original intent to either sell or hold the loan for the foreseeable future. When management's intent at origination or purchase is to sell the loan, the cash flows of that loan are presented as operating cash flows. When management's intent is to hold the loan for the foreseeable future, the cash flows of that loan are presented as investing cash flows.
Time Deposits in Financial Institutions	Time Deposits in Financial Institutions: Time deposits in financial institutions have original maturities over 90 days and are carried at cost.
Securities	Securities: Investment securities are classified at the time of purchase as available for sale or held-to-maturity. Debt securities classified as held to maturity are recorded at amortized cost when management has the positive intent and ability to hold them to maturity. Debt securities are classified as available-for-sale when management intends that they might be sold before maturity. Equity securities with readily determinable fair values are classified as available-for-sale. Securities available-for-sale are carried at fair value with unrealized holding gains and losses, net of taxes, reported in other comprehensive income or loss.
	Accreted discounts and amortized premiums are included in interest income using the level yield method, and realized gains or losses from sales of securities are calculated using the specific identification method.
	Management evaluates securities for other-than-temporary impairment (OTTI) at least on a quarterly basis, and more frequently when economic conditions warrant such an evaluation. Investment securities classified as available for sale or held-to-maturity are generally evaluated for OTTI under Statement of Financial Accounting Standards Accounting Standards Codification (ASC) 320, Accounting for Certain Investments in Debt and Equity Securities. However, certain purchased beneficial interests, including non-agency mortgage-backed securities, asset-backed securities, and collateralized debt obligations, that had credit ratings at the time of purchase of below AA are evaluated using the model outlined in ASC 325, Recognition of Interest Income and Impairment on Purchased Beneficial Interests and Beneficial Interests that Continue to be Held by a Transfer in Securitized Financial Assets.
	In determining OTTI under the ASC 320 model, management considers the extent and duration of the unrealized loss and the financial condition and near-term prospects of the issuer. Management also considers whether the market decline was affected by macroeconomic conditions, and assesses whether the Company intends to sell, or it is more likely than not it will be required to sell a security in an unrealized loss position before recovery of its amortized cost basis. The assessment of whether OTTI exists involves a high degree of subjectivity and judgment and is based on the information available to management at a point in time.
	The second segment of the portfolio uses the OTTI guidance provided by ASC 325 that is specific to purchased beneficial interests that, on the purchase date, were rated below AA. Under the ASC 325 model, the Company compares the present value of the remaining cash flows as estimated at the preceding evaluation date to the current expected remaining cash flows. An OTTI is deemed to have occurred if there has been an adverse change in the remaining expected future cash flows.
	When OTTI occurs in either model, the amount of the impairment recognized in earnings depends on the Company’s intent to sell the security or if it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) other-than-temporary impairment related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities the entire amount of impairment is recognized through earnings.
Federal Home Loan Bank (FHLB) Stock	Federal Home Loan Bank (FHLB) and Federal Reserve Bank (FRB) Stock: The Bank is a member of the FHLB and FRB system. Members are required to own a certain amount of FHLB and FRB stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB and FRB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income.
Loans Held for Sale	Conforming Mortgage Loans Held for Sale: Mortgage loans originated and intended for sale in the secondary market are carried at the fair value as of each balance sheet date, as determined by outstanding commitments from investors or what secondary markets are currently offering for portfolios with similar characteristics. The fair value includes the servicing value of the loans as well as any accrued interest. Mortgage loans held for sale are generally sold with servicing rights retained. Origination fees and costs are recognized in earnings at the time of origination for newly originated loans held for sale. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold.
	The Company’s conforming mortgage loans held for sale at fair value are Government-sponsored enterprise (GSE) or Government-eligible at December 31, 2014. These loans are considered to have reliable market price information and the fair value of these loans at December 31, 2014 was based on quoted market prices of similar assets and included the value of loan servicing.
	In scenarios of market disruptions, the current secondary market prices that are generally relied on to value GSE-eligible mortgage loans may not be readily available. In these circumstances, the Company may consider other factors, including: 1) quoted market prices for to-be-announced securities (for agency-eligible loans); 2) recent transaction settlements or traded but unsettled transactions for similar assets; 3) recent third party market transactions for similar assets; and 4) modeled valuations using assumptions that the Bank believes would be used by market participants in estimating fair value (assumptions may include prepayment rates, interest rates, volatilities, mortgage spreads and projected loss rates).
	Adjustments to reflect unrealized gains and losses resulting from changes in fair value and realized gains and losses upon ultimate sale of the loans are classified as part of Net Revenue on Mortgage Banking Activities on the Consolidated Statements of Operations.
	Non-Conforming Mortgage Loans Held for Sale: Non-conforming mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or fair value on an aggregate basis. A decline in the aggregate fair value of the loans below their aggregate carrying amount is recognized through a charge to earnings in the period of such a decline. Unearned income on the loans is taken into earnings when they are sold.
	SBA Loans Held for Sale: SBA loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated market value in the aggregate. Net unrealized losses are recognized through a valuation allowance by charges to income. Gains or losses realized on the sales of SBA loans are recognized at the time of sale and are determined by the difference between the net sales proceeds and the carrying value of the loans sold, adjusted for any servicing asset or liability. Gains and losses on sales of SBA loans are included in noninterest income.
Loan and Leases	Loans and Leases: Loans and leases (other than purchased credit-impaired loans and leases) that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff are stated at the principal balance outstanding, net of charged off amounts and unamortized purchase premiums and discounts and net of deferred loan fees and costs. The deferred net loan fees and costs, and purchase premiums and discounts are recognized in interest income as an adjustment to yield over the loan term using the effective interest method. Interest on loans and leases is credited to interest income as earned based on the interest rate applied to principal amounts outstanding. Interest income is accrued on the unpaid principal balance and is discontinued on a loan when management believes, after considering economic and business conditions and collection efforts, that the borrower’s financial condition is such that full collection of principal or interest becomes doubtful, regardless of the length of past due status. Generally loans are placed on nonaccrual status when they are greater than 90 days past due. When interest accrual is discontinued, all unpaid accrued interest is reversed against interest income. Interest received on such loans and leases is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. A charge-off is recorded at 180 days if the loan balance exceeds the fair value of the collateral less costs to sell. Commercial, commercial real estate and equipment finance loans are subject to a detailed review when 90 days past due to determine accrual status, or when payment is uncertain and a specific consideration is made to put a loan or lease on non-accrual status. Consumer loans, other than those secured by real estate, are typically charged off no later than 180 days past due. Loans and leases are returned to accrual status when the borrower has demonstrated a satisfactory payment trend subject to management’s assessment of the borrower’s ability to repay the loan.
Allowance for Loan and Lease Losses
	Allowance for Loan and Lease Losses: The allowance for loan and lease losses is a reserve established through a provision for loan and lease loses charged to expense, and represents management’s best estimate of probable losses that may be incurred within the existing loan and lease portfolio as of the balance sheet date. Subsequent recoveries, if any, are credited to the allowance. The Company performs an analysis of the adequacy of the allowance at least on a quarterly basis. Management estimates the allowance balance required using past loan and lease 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 and leases, but the entire allowance is available for any loan or lease that, in management’s judgment, should be charged off.
	The allowance consists of three elements; (i) specific valuation allowances established for probable losses on impaired loans and leases, (ii) quantitative valuation allowances calculated using loss experience for like loans and leases with similar characteristics and trends, adjusted, as necessary to reflect the impact of current conditions; and (iii) qualitative allowances determined based on environmental and other factors that may be internal or external to the Company.
	A loan or lease 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 or lease agreement. The Company evaluates all impaired loans and leases individually under the guidance of ASC 310, Receivables, primarily through the evaluation of collateral values and estimated cash flows. Loans and leases for which the terms have been modified and where the borrower is experiencing financial difficulties are considered troubled debt restructurings (TDR) and classified as impaired.
	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 and leases 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 or lease 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. The impairment amount on a collateral dependent loan is charged-off to the allowance and the impairment amount on a loan that is not collateral dependent is set-up as a specific reserve. TDRs are also measured at the present value of estimated future cash flows using the loan’s or lease’s effective rate at inception or at the fair value of collateral, less costs to sell, if repayment is expected solely from the collateral. For TDRs that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the allowance for loan and lease losses.
	During the year ended December 31, 2014, the Company enhanced the current methodologies, processes and controls over the allowance for loan and lease losses (ALLL), due to the Company's organic and acquisitive growth and changing profile.
	The following is a synopsis of the enhancements for each component of ALLL:
	•	Expand the look-back period to 28 rolling quarters to capture a full economic cycle.
	•	Utilize net historical losses versus gross historical losses.
	•	Expand the peer group used to determine industry average loss history to include three industry groups; 1) all U.S. financial and bank holding companies, 2) all California financial and bank holding companies, 3) the peer group average from the Uniform Bank Performance Report.
	•	Apply a segment specific loss emergence period to each segment's loss rate.
	•	Determine qualitative reserves is at each loan segment level based on a baseline risk weighting adjusted for current risks, trends and business conditions.
	•	Disaggregate certain qualitative factors to be determined on the portfolio segment level.
	These enhancements resulted in an increase of $264 thousand in the ALLL as compared to what it would have been using the old methodology at December 31, 2014.
	At December 31, 2014, the following portfolio segments have been identified: commercial and industrial - secured; commercial and industrial - unsecured; commercial real estate - retail; commercial real estate - office; commercial real estate - industrial; commercial real estate - hospitality; commercial real estate - acquisition and development; commercial real estate - condo conversion; commercial real estate - other; construction; SBA; leases; single family residence -1st trust deed (amortizing, interest only now amortizing, interest only, negative amortization, and Green Loans); single family residence -2nd trust deeds; other consumer. The Company categorizes loans and leases into risk categories based on relevant information about the ability of borrowers and lessees (also referred to as borrowers) to service their obligations such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans and leases individually by classifying the loans and leases as to credit risk. This analysis includes all loans and leases delinquent over 60 days and non-homogeneous loans and leases such as commercial and commercial real estate loans. Classification of problem SFR mortgage loans is performed on a monthly basis while analysis of non-homogeneous loans is performed on a quarterly basis.
	Loans secured by multi-family and commercial real estate properties generally involve a greater degree of credit risk than SFR mortgage loans. Because payments on loans secured by multi-family and commercial real estate properties are often dependent on the successful operation or management of the properties, repayment of these loans may be subject to adverse conditions in the real estate market or the economy. Commercial business loans are also considered to have a greater degree of credit risk than SFR mortgage loans due to the fact commercial business loans are typically made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business. As a result, the availability of funds for the repayment of commercial business loans may be substantially dependent on the success of the business itself (which, in turn, is often dependent in part upon general economic conditions). SBA business loans are similar to commercial business loans, but have additional credit enhancement provided by the U.S. Small Business Administration, for up to 85 percent of the loan amount for loans up to $150,000 and 75 percent of the loan amount for loans of more than $150,000. Commercial equipment leases are also similar to commercial business loans in that the leases are typically made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business. As a result, the availability of funds for the repayment of commercial equipment leases may be substantially dependent on the success of the business itself (which, in turn, is often dependent in part upon general economic conditions). Consumer and other real estate loans may entail greater risk than do SFR mortgage loans given that collection of these loans is dependent on the borrower’s continuing financial stability and, thus, are more likely to be adversely affected by job loss, divorce, illness, or personal bankruptcy. Green Loans are also considered to carry a higher degree of credit risk due to their unique cash flows. Credit risk on this asset class is also managed through the completion of regular re-appraisals of the underlying collateral and monitoring of the borrower’s usage of this account to determine if the borrower is making monthly payments from external sources or “drawdowns” on their line. In cases where the property values have declined to levels less than the original loan-to-value, or other levels deemed prudent by the Company, the Company may curtail the line and/or require monthly payments or principal reductions to bring the loan in balance.
	Classified Assets: Federal regulations provide for the classification of loans, leases, and other assets, such as debt and equity securities considered to be of lesser quality, as “substandard,” “doubtful” or “loss.” An asset is considered “substandard” if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. “Substandard” assets include those characterized by the “distinct possibility” that the insured institution will sustain “some loss” if the deficiencies are not corrected. Assets classified as “doubtful” have all of the weaknesses inherent in those classified “substandard,” with the added characteristic that the weaknesses present make “collection or liquidation in full,” on the basis of currently existing facts, conditions, and values, “highly questionable and improbable.” Assets classified as “loss” are those considered “uncollectible” and of such little value that their continuance as assets without the establishment of a specific loss reserve is not warranted. When an insured institution classifies problem assets as “loss,” it is required to charge off such amount. The Bank’s determination as to the classification of its assets and the amount of its valuation allowances is subject to review by its primary regulator, which may order the establishment of additional general or specific loss allowances.
Troubled Debt Restructurings (TDR)	Troubled Debt Restructurings (TDR): A loan is identified as a TDR when a borrower is experiencing financial difficulties and for economic or legal reasons related to these difficulties, the Company grants a concession to the borrower in the restructuring that it would not otherwise consider. The Company has granted a concession when, as a result of the restructuring to a troubled borrower, it does not expect to collect all amounts due, including principal and/or interest accrued at the original terms of the loan. The concessions may be granted in various forms, including a below-market change in the stated interest rate, a reduction in the loan balance or accrued interest, an extension of the maturity date, or a note split with principal forgiveness. Loans for which the borrower has been discharged under Chapter 7 bankruptcy are considered collateral dependent TDRs, impaired at the date of discharge, and charged down to the fair value of collateral less cost to sell. A restructuring executed at an interest rate that is at market interest rates based on the current credit characteristics of the borrower is not a TDR.
	The Company’s policy is to place consumer loan TDRs, except those that were performing prior to TDR status, on non-accrual status for a minimum period of 6 months. Commercial TDRs are evaluated on a case-by-case basis for determination of whether or not to place on non-accrual status. Loans qualify for return to accrual status once they have demonstrated performance with the restructured terms of the loan agreement for a minimum of 6 months. Initially, all TDRs are reported as impaired. Generally, TDRs are classified as impaired loans and reported as TDRs for the remaining life of the loan. Impaired and TDR classification may be removed if the borrower demonstrates compliance with the modified terms for a minimum of 6 months and through one fiscal year-end and the restructuring agreement specifies a market rate of interest equal to that which would be provided to a borrower with similar credit at the time of restructuring. In the limited circumstance that a loan is removed from TDR classification it is the Company’s policy to continue to base its measure of loan impairment on the contractual terms specified by the loan agreement.
Concentration of Credit Risk	Concentration of Credit Risk: Most of the Company’s lending activity is with customers located within San Diego, Los Angeles, Orange and Riverside Counties, California. Therefore, the Company’s exposure to credit risk is significantly affected by economic conditions in those areas. Our loans are concentrated geographically in the Southern California market place.
Purchased Credit-Impaired Loans and Leases	Purchased Credit-Impaired Loans: The Company purchases loans with and without evidence of credit quality deterioration since origination. Evidence of credit quality deterioration as of the purchase date may include statistics such as prior loan modification history, updated borrower credit scores and updated loan or lease-to-value (LTV) ratios, some of which may not be immediately available as of the purchase date. Purchased loans with evidence of credit quality deterioration where the Company estimates that it will not receive all contractual payments are accounted for as purchased credit impaired loans (PCI loans). The excess of the cash flows expected to be collected on PCI loans, measured as of the acquisition date, over the estimated fair value is referred to as the accretable yield and is recognized in interest income over the remaining life of the loan or lease using a level yield methodology. The difference between contractually required payments as of the acquisition date and the cash flows expected to be collected is referred to as the non-accretable difference. PCI loans that have similar risk characteristics, primarily credit risk, collateral type and interest rate risk, are pooled and accounted for as a single unit with a single composite interest rate and an aggregate expectation of cash flows.
	Loans that were acquired during 2012 in connection with the Beach and Gateway acquisitions and during 2013 in connection with the PBOC acquisition that were considered credit impaired were recorded at fair value at the acquisition date and the related allowance for loan and lease losses was not carried over to the Company’s allowance. Any losses on such loans are charged against the non-accretable difference established in purchase accounting and are not reported as charge-offs until such non-accretable difference is fully utilized. These loans were evaluated individually and were not part of the aforementioned pools.
	The Company estimates cash flows expected to be collected over the life of the loan using management’s best estimate which is derived using current key assumptions such as default rates, loss severity and payment speeds. If, upon subsequent evaluation, the Company determines it is probable that the present value of the expected cash flows have decreased due to a deterioration of credit, the PCI loan is considered further impaired which will result in a charge to the provision for loan and lease losses and a corresponding increase to the allowance for loan and lease losses. If, upon subsequent evaluation, it is probable that there is an increase in the present value of the expected cash flows, the Company will reduce any remaining allowance. If there is no remaining allowance, the Company will recalculate the amount of accretable yield as the excess of the revised expected cash flows over the current carrying value resulting in a reclassification from non-accretable difference to accretable yield. The present value of the expected cash flows for PCI purchased loan pools is determined using the PCI loans’ effective interest rate, adjusted for changes in the PCI loans’ interest rate indexes. Adjustments in interest rate assumptions and prepayment behavior do not impact the Company’s assessment of credit impairment. The present value of the expected cash flows for PCI loans and leases acquired through mergers with other banks includes, in addition to the above, an evaluation of the credit worthiness of the borrower. Loan dispositions may include sales of loans, receipt of payments in full from the borrower or foreclosure. Write-downs are not recorded on the PCI loan pool until actual losses exceed the remaining non-accretable difference. To date, no write-downs have been recorded for the PCI loans held by the Company.
Other Real Estate Owned	Other Real Estate Owned: Other real estate owned (OREO), which represents real estate acquired through foreclosure in satisfaction of commercial and real estate loans, is initially recorded at fair value less estimated selling costs of the real estate, based on current independent appraisals obtained at the time of acquisition, less costs to sell when acquired, establishing a new cost basis. Loan balances in excess of fair value of the real estate acquired at the date of acquisition are charged to the allowance for loan losses. Gains and losses on the sale of OREO are included in Net Gain on Sales of Other Real Estate Owned, reductions in fair value subsequent to foreclosure are included in Valuation Allowance for Other Real Estate Owned and any subsequent operating expenses or income of such properties are included in All Other Expense on the Consolidated Statements of Operations.
Premises and Equipment	Premises and Equipment: Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method with the following estimated useful lives: building 40 years and leasehold improvements-life of lease, and furniture, fixtures, and equipment 3 to 7 years. Maintenance and repairs are charged to expense as incurred, and improvements that extend the useful lives of assets are capitalized.
Bank Owned Life Insurance	Bank Owned Life Insurance: The Bank has purchased life insurance policies on certain key current and former executives. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Servicing Rights - Mortgage (Fair Value Method) and Small Business Administration Loans (Amortized Cost Method)	Servicing Rights-Mortgage (Fair Value Method): A servicing asset or liability is recognized when undertaking an obligation to service a financial asset under mortgage servicing contract, including a transfer of the servicer’s financial assets that meet the requirements for sale accounting. Such servicing asset or liability is initially measured at fair value based on either market prices for comparable servicing contracts or alternatively is based on a valuation model that is based on the present value of the contractually specified servicing fee, net of servicing costs, over the estimated life of the loan, using a discount rate based on the related note rate and is recorded on the Consolidated Statements of Operations.
	Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income.
	Under the fair value measurement method, the Company measures servicing rights at fair value at each reporting date and reports changes in fair value of servicing assets in earnings in the period in which the changes occur, and are included with Net Revenue on Mortgage Banking Activities on the Consolidated Statements of Operations. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimates and actual prepayment speeds and default rates and losses. Currently the Company does not hedge the income statement effects of changes in fair value of the servicing assets.
	Servicing fee income, which is reported in Loan Servicing Income on the Consolidated Statements of Operations, is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal; or a fixed amount per loan and are recorded as income when earned. Late fees and ancillary fees related to loan servicing are not material.
	Servicing Rights-Small Business Administration Loans (Amortized Cost Method): As a general course of business, the Bank originates and sells the guaranteed portion of its SBA loans. To calculate the gain (loss) on sales of SBA loans, the Bank’s investment in the loan is allocated among the retained portion of the loan, the servicing retained, the interest-only strip and the sold portion of the loan, based on the relative fair market value of each portion. The gain (loss) on the sold portion of the loan is recognized at the time of sale based on the difference between sale proceeds and the amount of the allocated investment to the sold portion of the loan.
	The portion of the servicing fees that represent contractually specified servicing fees (contractual servicing) is reflected as a servicing asset and is amortized over the estimated life of the servicing; in the event future prepayments exceed management’s estimates and future expected cash flows are inadequate to cover the servicing asset, impairment is recognized. The portion of servicing fees in excess of contractual servicing fees are reflected as interest-only (I/O) strips receivable, which is included in Other Assets on the Consolidated Statements of Financial Condition. The I/O strips receivable are carried at fair value, with unrealized gains and losses recorded in the Consolidated Statements of Operations.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets: Goodwill represents the excess purchase price of businesses acquired over the fair value of the identifiable net assets acquired and is assigned to specific reporting units. Goodwill is not subject to amortization and is evaluated for impairment annually, during the third fiscal quarter, or more frequently in the interim if events occur or circumstances change indicating it would more likely than not result in a reduction of the fair value of a reporting unit below its carrying value. Goodwill is evaluated for impairment by either performing a qualitative evaluation or a two-step quantitative test. The qualitative evaluation is an assessment of factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. Discounted cash flow estimates, which include significant management assumptions relating to revenue growth rates, net interest margins, weighted average cost of capital, and future economic and market conditions, are used to determine fair value under the two-step quantitative test. In Step 1, the fair value of a reporting unit is compared to its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired, and it is not necessary to continue to Step 2 of the impairment process. Otherwise, Step 2 is performed where the implied fair value of goodwill is compared to the carrying value of goodwill in the reporting unit. If a reporting unit's carrying value exceeds fair value, the difference is charged to noninterest expense.
	Other intangible assets represent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights, or because the asset is capable of being sold or exchanged either separately or in combination with a related contract, asset or liability. Other intangible assets with finite useful lives are amortized to noninterest expense over their estimated useful lives and are evaluated for impairment whenever events occur or circumstances change indicating the carrying amount of the asset may not be recoverable.
Reserve for Unfunded Commitments	Reserve for Unfunded Commitments: The reserve for unfunded commitments provides for probable losses inherent with funding the unused portion of legal commitments to available to lend. The unfunded reserve calculation includes factors that are consistent with ALLL methodology for funded loans using the loss given default, probability of default and a draw down factor applied to the underlying borrower risk and facility grades. Changes in the reserve for unfunded credit commitments, within Accrued Expenses and Other Liabilities, is reported as a component of All Other Expense on the Consolidated Statements of Operations.
Reserve for Loss on Repurchase Loans	Reserve for Loss on Repurchased Loans: In the ordinary course of business, as loans held for sale are sold, the Bank makes standard industry representations and warranties about the loans. The Bank may have to subsequently repurchase certain loans or reimburse certain investor losses due to defects that may have occurred in the origination of the loans. Such defects include documentation or underwriting errors. In addition, certain investor contracts require the Bank to repurchase loans from previous whole loan sales transactions that experience early payment defaults. If there are no such defects or early payment defaults, the Bank has no commitment to repurchase loans that it has sold. The level of reserve for loss on repurchased loans is an estimate that requires considerable management judgment. The Bank’s reserve is based upon the expected future repurchase trends for loans already sold in whole loan sale transactions and the expected valuation of such loans when repurchased, which include first and second trust deed loans. At the point when loss reimbursements are made directly to the investor, the reserve for loss reimbursements on sold loans is charged for the losses incurred.
Business Combinations	Business Combinations: Business combinations are accounted for under the acquisition method of accounting in accordance with ASC 805, Business Combinations. Under the acquisition method the acquiring entity in a business combination recognizes 100 percent of the acquired assets and assumed liabilities, regardless of the percentage owned, at their estimated fair values as of the date of acquisition. Any excess of the purchase price over the fair value of net assets and other identifiable intangible assets acquired is recorded as goodwill. To the extent the fair value of net assets acquired, including other identifiable assets, exceed the purchase price, a bargain purchase gain is recognized. Assets acquired and liabilities assumed from contingencies must also be recognized at fair value, if the fair value can be determined during the measurement period. Results of operations of an acquired business are included in the statement of operations from the date of acquisition. Acquisition-related costs, including conversion and restructuring charges, are expensed as incurred.
Long-term Assets	Long-term Assets: Premises and equipment and other long-term assets are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.
Deferred Financing Costs	Deferred Financing Costs: Deferred financing costs associated with the Company’s senior notes and junior subordinated amortizing notes are included in Notes Payable on the Consolidated Statements of Financial Condition. The deferred financing costs are being amortized on a basis that approximates a level yield method over the eight-year term of the senior notes and the five-year term of the junior subordinated amortizing notes.
Loan Commitments and Related Financial Statements	Loan Commitments and Related Financial Statements: Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Stock-Based Compensation	Stock-Based Compensation: Compensation cost is recognized for stock appreciation rights, stock options and restricted stock awards issued to employees and directors, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.
Income Taxes	Income Taxes: Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance is established when necessary to reduce deferred tax assets when it is more-likely-than-not that a portion or all of the net deferred tax assets will not be realized. As of December 31, 2014, the Company had a net deferred tax asset of $16.4 million, net of a $0 valuation allowance and the Company had a net deferred tax asset of $0, net of a $17.3 million valuation allowance as of December 31, 2013. The decrease in the valuation allowance against its federal and state deferred tax assets was due primarily to current year taxable income, including strong core earnings and management’s projection of taxable income for future tax years. See further discussion in Note 13.
	The Company and its subsidiaries are subject to U.S. Federal income tax as well as income tax in multiple state jurisdictions. The Company is no longer subject to examination by U.S. Federal taxing authorities for years before 2010, with the exception of Gateway Bancorp, a predecessor entity, which is currently under exam by the Internal Revenue Service for the 2008 and 2009 tax years. The statute of limitations for the assessment of California Franchise taxes has expired for tax years before 2010; other state income and franchise tax statutes of limitations vary by state.
	Tax positions that are uncertain but meet a more likely than not recognition threshold are initially and subsequently measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position meets the more likely than not recognition threshold considers the facts, circumstances and information available at the reporting date and is subject to management's judgment. The Company recognizes interest and/or penalties related to income tax matters in income tax expense.
Earnings Per Share	Earnings Per Common Share: Earnings per common share is computed under the two-class method. Basic earnings per common share (EPS) is computed by dividing net income allocated to common stockholders by the weighted average number of shares outstanding, including the minimum number of shares issuable under purchase contracts relating to the tangible equity units (see the discussion of the tangible equity units in Note 18). Diluted EPS is computed by dividing net income allocated to common stockholders by the weighted average number of shares outstanding, adjusted for the dilutive effect of the restricted stock units, the potentially issuable shares in excess of the minimum under purchase contracts relating to the tangible equity units, outstanding stock options, and warrants to purchase common stock. Net income allocated to common stockholders is computed by subtracting income allocated to participating securities, participating securities dividends and preferred stock dividend from net income. Participating securities are instruments granted in share-based payment transactions that contain rights to receive nonforfeitable dividends or dividend equivalents, which includes the Stock Appreciation Rights to the extent they confer dividend equivalent rights, as described under “Stock Appreciation Rights” in Note 16.
Comprehensive Income (Loss)	Comprehensive Income (Loss): Comprehensive income (loss) consists of net income (loss) and other comprehensive income or loss. Other comprehensive income or loss includes unrealized gains and losses on securities available for sale and interest rate swap, net of tax, which are recognized as a separate component of stockholders’ equity.
Accounting for Derivative Instruments and Hedging Activities	Accounting for Derivative Instruments and Hedging Activities: The Company records its derivative instruments at fair value as either assets or liabilities on the Consolidated Statements of Financial Condition in other assets and accrued expenses and other liabilities, respectively. The change in derivative instruments fair value is recorded in current earnings in Net Revenue on Mortgage Banking Activities on the Consolidated Statements of Operations.
	The Company enters into commitments to originate mortgage loans whereby the interest rate on the loan is set prior to funding (interest rate lock commitments, or IRLCs). Interest rate lock commitments on mortgage loans that are intended to be sold are considered derivatives and are recorded at fair value in Other Assets or Accrued Expenses and Other Liabilities on the Consolidated Statements of Financial Condition with the change in fair value recorded in the Consolidated Statements of Operations. The estimated fair value is based on current market prices for similar instruments.
	The Company hedges the risk of the overall change in the fair value of loan commitments to borrowers by selling forward contracts on securities of GSEs. Forward contracts on securities are considered derivative instruments. The Company has not formally designated these derivatives as a qualifying hedge relationship and accordingly, accounts for such forward contracts as freestanding derivatives with changes in fair value recorded to earnings each period.
Loss Contingencies	Loss Contingencies: Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there now are such matters that will have a material effect on the consolidated financial statements.
Dividend Restriction	Dividend Restriction: Banking regulations require maintaining certain capital levels and may limit the dividends paid by the Bank to the Company or by the Company to stockholders.
Fair Value of Financial Instruments	Fair Values of Financial Instruments: The Company measures certain assets and liabilities on a fair value basis, in accordance with ASC Topic 820, "Fair Value Measurement". Fair value is used on a recurring basis for certain assets and liabilities in which fair value is the primary basis of accounting. Examples of these include derivative instruments and available for sale securities. Additionally, fair value is used on a non-recurring basis to evaluate assets or liabilities for impairment in accordance with ASC Topic 825, "Financial Instruments". Examples of these include impaired loans, long-lived assets, OREO, goodwill, and core deposit intangible assets as well as loans held for sale accounted for at the lower of cost or fair value.
	Fair value is the exchange price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants. When observable market prices are not available, fair value is estimated using modeling techniques such as discounted cash flow analysis. These modeling techniques utilize assumptions that market participants would use in pricing the asset or the liability, including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset, and the risk of nonperformance. Depending on the nature of the asset or liability, the Company uses various valuation techniques and assumptions when estimating the instrument’s fair value. Considerable judgment may be involved in determining the amount that is most representative of fair value.
	To increase consistency and comparability of fair value measures, ASC Topic 820, "Fair Value Measurement" established a three-level hierarchy to prioritize the inputs used in valuation techniques between observable inputs among (i) observable inputs that reflect quoted prices in active markets, (ii) inputs other than quoted prices with observable market data, and (iii) unobservable data such as the Company’s own data or single dealer non-binding pricing quotes. The Company assesses the valuation hierarchy for each asset or liability measured at the end of each quarter, as a result assets or liabilities may be transferred within hierarchy levels due to changes in availability of observable market inputs to measure fair value at the measurement date. Further information regarding the Company's policies and methodology used to measure fair value is presented in Note 3.
Transfer of Financial Assets	Transfer of Financial Assets: Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is generally considered to have been surrendered when (i) the transferred assets are legally isolated from the Company or its consolidated affiliates, even in bankruptcy or other receivership, (ii) the transferee has the right to pledge or exchange the assets with no conditions that constrain the transferee and provide more than a trivial benefit to the Company, and (iii) the Company does not maintain the obligation or unilateral ability to reclaim or repurchase the assets.
	The Company sells financial assets in the normal course of business, the majority of which are residential mortgage loan sales primarily to government-sponsored enterprises through established programs and other individual or portfolio loan and securities sales. In accordance with accounting guidance for asset transfers, the Company considers any ongoing involvement with transferred assets in determining whether the assets can be derecognized from the balance sheet. With the exception of servicing and certain performance-based guarantees, the Company’s continuing involvement with financial assets sold is minimal and generally limited to market customary representation and warranty clauses.
	When the Company sells financial assets, it may retain servicing rights and/or other interests in the financial assets. The gain or loss on sale depends on the previous carrying amount of the transferred financial assets and the consideration received and any liabilities incurred in exchange for the transferred assets. Upon transfer, any servicing assets and other interests held by the Company are carried at the lower of cost or fair value.
Fee Revenue	Fee Revenue: Generally, fee revenue from deposit service charges and loans is recognized when earned, except where ultimate collection is uncertain, in which case revenue is recognized when received.
Marketing Costs	Marketing Costs: Marketing costs are expensed as incurred.
Adoption of New Accounting Standards	Adoption of New Accounting Standards
	In January 2014, the FASB issued guidance within ASU 2014-1, “Accounting for Investments in Qualified Affordable Housing Projects.” The amendments in ASU 2014-1to Topic 323, “Equity Investments and Joint Ventures,” provide guidance on accounting for investments by a reporting entity in flow-through limited liability entities that manage or invest in affordable housing projects that qualify for the low-income housing tax credit. The amendments permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received, and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). The amendments are effective for fiscal years, and interim periods within those years, beginning after December 31, 2014 and should be applied retrospectively to all periods presented. Early adoption is permitted. All of the Company’s affordable housing fund investments are within the scope of this guidance. The Company does not expect the application of this guidance to have a material impact on the Company's financial statements.
	In January 2014, the FASB issued ASU No. 2014-4, “Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure.” ASU 2014-4 clarifies that an in substance repossession or foreclosure has occurred, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure. Interim and annual disclosure is required of both the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure. ASU 2014-4 is effective using either the modified retrospective transition method or a prospective transition method for fiscal years and interim periods within those years, beginning after December 15, 2014, and early adoption is permitted. The Company does not expect the application of this guidance to have a material impact on the Company's financial statements.
	In May 2014, the FASB issued ASU No. 2014-9, “Revenue From Contracts With Customers”, that outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The ASU is based on the principle that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to fulfill a contract. Entities have the option of using either a full retrospective or a modified retrospective approach for the adoption of the new standard. The ASU becomes effective for Company at the beginning of its 2017 fiscal year; early adoption is not permitted. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-11, “Transfers and Servicing: Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures”. The ASU changes the accounting for repurchase-to-maturity transactions to secured borrowing accounting. In addition, for repurchase financing arrangements, the amendments require separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. The ASU also requires disclosures for certain transactions comprising (1) a transfer of a financial asset accounted for as a sale and (2) an agreement with the same transferee entered into in contemplation of the initial transfer that results in the transferor retaining substantially all of the exposure to the economic return on the transferred financial asset throughout the term of the transaction. There are also additional disclosure requirements for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions that are accounted for as secured borrowings. ASU 2014-11 is effective using either the modified retrospective transition method or a prospective transition method for fiscal years and interim periods within those years, beginning after December 15, 2014. The Company does not expect the application of this guidance to have a material impact on the Company's financial statements.
	In June 2014, the FASB issued ASU No. 2014-12, “Compensation—Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period”. The ASU requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Topic 718 as it relates to awards with performance conditions that affect vesting to account for such awards. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. ASU 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements.
	In August 2014, the FASB issued ASU 2014-14, “Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310-40), Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure.” Under ASU 2014-14, a mortgage loan should be derecognized and a separate receivable based on the principal and interest expected to be recovered from the governmental guarantor should be recognized upon foreclosure when all of the following conditions exist: a government guarantee exists that is not separable from the loan prior to the foreclosure; as of the date of the foreclosure the creditor has the intent to convey the real estate to the governmental agency that issued the guarantee, to make a claim on the guarantee and the creditor has the ability to recover amounts due from the governmental entity as a result of the claim; and, as of the time of the foreclosure, the claim amount that is based on the fair value of the real estate is fixed. ASU 2014-14 is effective using either the modified retrospective transition method or a prospective transition method for fiscal years and interim periods within those years, beginning after December 15, 2014. The Company does not expect the application of this guidance to have a material impact on the Company's financial statements.

Summary of Amortized Cost and Fair Value of Available-for-Sale Investment Securities Portfolio	The following table presents amortized cost and fair value of the available-for-sale investment securities portfolio by expected maturity. In the case of residential mortgage-backed securities and SBA loan pool securities, expected maturities may differ from contractual maturities because borrowers generally have the right to call or prepay obligations with or without call or prepayment penalties. For that reason, mortgage-backed securities and SBA loan pool securities are not included in the maturity categories.
