NOTE 1—BASIS OF PRESENTATION

        PacWest Bancorp is a bank holding company registered under the Bank Holding Company Act of 1956, as amended. Our principal business is to serve as a holding company for our banking subsidiary, Pacific Western Bank, which we refer to as Pacific Western or the Bank. When we say "we", "our" or the "Company", we mean the Company on a consolidated basis with the Bank. When we refer to "PacWest" or to the holding company, we are referring to the parent company on a stand-alone basis.

        Pacific Western is a full-service commercial bank offering a broad range of banking products and services including: accepting demand, money market, and time deposits; originating loans, including commercial, real estate construction, SBA guaranteed and consumer loans; and providing other business-oriented products. Our operations are primarily located in Southern California extending from California's Central Coast to San Diego County; we also operate three banking offices in the San Francisco Bay area, all of which were added through the FDIC-assisted acquisition of Affinity Bank, or Affinity, in August 2009. The Bank focuses on conducting business with small to medium sized businesses in our marketplace and the owners and employees of those businesses. The majority of our loans are secured by the real estate collateral of such businesses. Our asset-based lending function operates in Arizona, California, Texas, and the Pacific Northwest. Our equipment leasing function, added through the acquisition of Pacific Western Equipment Finance, or PWE Finance, (formerly Marquette Equipment Finance) on January 3, 2012, is based in Utah and has lease receivables in 45 states.

        We generate our revenue primarily from interest received on loans and leases and, to a lesser extent, from interest received on investment securities, and fees received in connection with deposit services, extending credit and other services offered, including foreign exchange services. Our major operating expenses are the interest paid by the Bank on deposits and borrowings, compensation and general operating expenses. The Bank relies on a foundation of locally generated and relationship-based deposits. The Bank has a relatively low cost of funds due to a high percentage of noninterest-bearing and low cost deposits.

        We have completed 24 acquisitions since May 2000, including PWE Finance and the April 3, 2012 acquisition of Celtic Capital Corporation, or Celtic, an asset-based lending company based in Santa Monica, California. See Note 2,Aquisitions, for more information about the PWE Finance acquisition and Note 14,Subsequent Events, for more information regarding the Celtic acquisition.

Basis of Presentation

        The accounting and reporting policies of the Company are in accordance with U.S. generally accepted accounting principles, which we may refer to as GAAP. All significant intercompany balances and transactions have been eliminated.

        Our financial statements reflect all adjustments that are, in the opinion of management, necessary to present a fair statement of the results for the interim periods presented. Certain information and note disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. The interim operating results are not necessarily indicative of operating results for the full year.

NOTE 1—BASIS OF PRESENTATION (Continued)

Use of Estimates

        Management of the Company has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period to prepare these consolidated financial statements in conformity with GAAP. Actual results could differ from those estimates. Material estimates subject to change in the near term include, among other items, the allowances for credit losses, the carrying value of other real estate owned, the carrying value of intangible assets, the carrying value of the FDIC loss sharing asset and the realization of deferred tax assets.

        Management made significant estimates and exercised significant judgment in estimating fair values and accounting for the acquired assets and assumed liabilities in the PWE Finance acquisition.

Reclassifications

        Certain prior period amounts have been reclassified to conform to the current period's presentation format. During the second quarter of 2011, we reclassified recoveries on covered loans such that recoveries now reduce the credit loss provision for covered loans rather than increase FDIC loss sharing income. Such reclassifications had no effect on reported net earnings or losses.

NOTE 2—ACQUISITIONS

        On January 3, 2012, Pacific Western Bank completed the acquisition of Marquette Equipment Finance (later renamed Pacific Western Equipment Finance, or PWE Finance), an equipment leasing company located in Midvale, Utah. Pacific Western Bank acquired all of the capital stock of PWE Finance for $35 million in cash. The acquisition diversified the Company's loan portfolio, expanded the Company's product lines, and deployed excess liquidity into higher yielding assets.

        At January 3, 2012, PWE Finance had $162.2 million in gross leases and leases in process outstanding, with no leases on nonaccrual status. In addition, Pacific Western Bank assumed $154.8 million in outstanding debt and other liabilities, which included $128.7 million payable to PWE Finance's former parent. Pacific Western Bank repaid PWE Finance's intercompany debt on the closing date from its excess liquidity on deposit at the Federal Reserve Bank.

        See Note 14,Subsequent Events, for information on acquisitions after March 31, 2012.

NOTE 3—GOODWILL AND OTHER INTANGIBLE ASSETS

        Goodwill arises from business combinations and represents the excess of the purchase price over the fair value of the net assets and other identifiable intangible assets acquired. Goodwill and other intangible assets deemed to have indefinite lives generated from purchase business combinations are not subject to amortization and are instead tested for impairment no less than annually. Impairment is determined in accordance with ASC 350, "Intangibles—Goodwill and Other" and is based on the reporting unit. Impairment exists when the carrying value of goodwill exceeds its implied fair value. An impairment loss would be recognized in an amount equal to that excess and would be included in noninterest expense in the consolidated statement of earnings. Our annual impairment test of goodwill resulted in no impact on our results of operations and financial condition.

NOTE 3—GOODWILL AND OTHER INTANGIBLE ASSETS (Continued)

        The following table presents the changes in the carrying amount of goodwill for the period indicated:

	Goodwill
	(In thousands)
Balance, December 31, 2011	$	39,141
Tax deductible addition from the PWE Finance acquisition		17,003
Balance, March 31, 2012	$	56,144

        Our intangible assets with definite lives are core deposit intangibles, or CDI, and customer relationship intangibles, or CRI. These intangible assets are amortized over their useful lives to their estimated residual values and reviewed for impairment at least quarterly. The amortization expense represents the estimated decline in the value of the underlying deposits or loan customers acquired.

        The following table presents the changes in CDI and CRI and the related accumulated amortization for the periods indicated:

Net CDI and CRI, end of period	$	17,380		$	17,415		$	23,536

        The aggregate amortization expense related to the intangible assets is expected to be $6.2 million for 2012. The estimated aggregate amortization expense related to these intangible assets for each of the subsequent four years is $4.8 million for 2013, $3.3 million for 2014, $3.1 million for 2015, and $1.4 million for 2016.

        Mortgage-backed securities have contractual terms to maturity and require periodic payments to reduce principal. In addition, expected maturities may differ from contractual maturities because obligors and/or issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

        We reviewed the securities that were in a continuous loss position less than 12 months and longer than 12 months at March 31, 2012, and concluded that their losses were a result of the level of market interest rates relative to the types of securities and not a result of the underlying issuers' abilities to repay. Accordingly, we determined that the securities were temporarily impaired. Additionally, we have no plans to sell these securities and believe that it is more likely than not we would not be required to sell these securities before recovery of their amortized cost. Therefore, we did not recognize the temporary impairment in the consolidated statements of earnings.

FHLB Stock

        At March 31, 2012, the Company had a $43.9 million investment in Federal Home Loan Bank of San Francisco ("FHLB") stock carried at cost. In January 2009, the FHLB announced that it suspended excess FHLB stock redemptions and dividend payments. Since this announcement, the FHLB has declared and paid cash dividends in 2010, 2011and 2012, though at rates less than those paid in the past, and repurchased certain amounts of our excess stock at carrying value. We evaluated the carrying value of our FHLB stock investment at March 31, 2012, and determined that it was not impaired. Our evaluation considered the long-term nature of the investment, the current financial and liquidity position of the FHLB, the actions being taken by the FHLB to address its regulatory situation, repurchase activity of excess stock by the FHLB, and our intent and ability to hold this investment for a period of time sufficient to recover our recorded investment.

        In addition to our internal risk rating process, our federal and state banking regulators, as an integral part of their examination process, periodically review the Company's loan risk rating classifications. Our regulators may require the Company to recognize rating downgrades based on their judgments related to information available to them at the time of their examinations. Risk rating downgrades generally result in higher provisions for credit losses.

NOTE 8—BORROWINGS, SUBORDINATED DEBENTURES AND BROKERED DEPOSITS

Debt Termination Expense—FHLB Advances and Subordinated Debentures

        In March 2012, the Company incurred $22.6 million in debt termination expense related to the prepayment of $225.0 million in fixed-rate term FHLB advances and the early redemption of $18.6 million in fixed-rate subordinated debentures for Trust CI and Trust I. The Company used a combination of excess cash and collateralized overnight FHLB advances to repay these debt instruments. The FHLB advances were composed of $200 million maturing in December 2017 with a fixed rate of 3.16% and $25 million due in January 2018 with a fixed rate of 2.61%. The agreements for these FHLB advances had an early prepayment penalty or fee for payoffs before maturity. The Trust CI subordinated debenture was in the amount of $10.3 million, due in March 2030 and bearing a fixed rate of 11.00%. The Trust I subordinated debenture was for $8.3 million with a maturity date of September 2030 and fixed rate of 10.6%.

Borrowings

        As of March 31, 2012, there were $179.5 million in outstanding FHLB advances borrowed on an overnight basis and bearing an interest rate of 0.13%. Our aggregate remaining borrowing capacity under the FHLB secured lines of credit was $1.0 billion at March 31, 2012. As of March 31, 2012, our FHLB advances were secured by all of our loans and leases under a blanket lien, in addition to securities with a carrying value of $29.0 million. Additionally, the Bank had secured borrowing capacity from the Federal Reserve discount window of $375.4 million at March 31, 2012. The Bank also maintains unsecured lines of credit of $45.0 million with correspondent banks for the purchase of overnight funds; these lines are subject to availability of funds.

        Included in borrowings are $13.6 million of non-recourse notes added through the PWE Finance acquisition, in which the payment stream of certain of its leases were sold to third parties. The debt is secured by the equipment in the leases and all interest rates are fixed. As of March 31, 2012, the weighted average interest rate of the notes was 6.84% with a weighted average remaining maturity of 2.4 years.

Subordinated Debentures

NOTE 8—BORROWINGS, SUBORDINATED DEBENTURES AND BROKERED DEPOSITS (Continued)

        The Company had an aggregate amount of $108.3 million in subordinated debentures outstanding at March 31, 2012. These subordinated debentures were issued in five separate series. Each issuance had a maturity of thirty years from its date of issue. The subordinated debentures are variable rate instruments and are each callable at par with no prepayment penalty. The subordinated debentures were issued to trusts established by us or entities we have acquired, which in turn issued trust preferred securities, which totaled $105.0 million at March 31, 2012. The proceeds of the subordinated debentures were used primarily to fund several of our acquisitions and to augment regulatory capital.

        The Company includes in Tier 1 capital an amount of trust preferred securities equal to no more than 25% of the sum of all core capital elements, which is generally defined as shareholders' equity less goodwill, net of any related deferred income tax liability. At March 31, 2012, the amount of trust preferred securities included in Tier I capital was $105.0 million.

        Notification to the Federal Reserve Board, or FRB, is required prior to our declaring and paying a dividend to our stockholders during any period in which our quarterly and/or cumulative twelve-month net earnings are insufficient to fund the dividend amount. Interest payments made by the Company on subordinated debentures are considered dividend payments under FRB regulations. This notification requirement is included in regulatory guidance regarding safety and soundness surrounding capital and includes other non-financial measures such as asset quality and credit concentrations. Should the FRB object to our dividend payments, we would be precluded from paying interest on our subordinated debentures. Payments would not commence until approval is received or we no longer need to provide notice under applicable guidance.

Brokered Deposits

        Brokered deposits totaled $37.4 million at March 31, 2012 and are included in the interest-bearing deposits balance on the accompanying condensed consolidated balance sheets. Such amount represented customer deposits that were subsequently participated with other FDIC-insured financial institutions through the CDARS program as a means to provide FDIC deposit insurance coverage for the full amount of our customers' deposits.

NOTE 9—COMMITMENTS AND CONTINGENCIES

Lending Commitments

        The Bank is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets. The contract or notional amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments.

        Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily

represent future cash requirements. Commitments to extend credit totaled $690.5 million and $691.5 million at March 31, 2012 and December 31, 2011, respectively.

        Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support private borrowing arrangements. Most guarantees expire within one year from the date of issuance. The Company generally requires collateral or other security to support financial instruments with credit risk. Standby letters of credit totaled $28.9 million and $32.0 million at March 31, 2012 and December 31, 2011, respectively.

        The Company has investments in low income housing project partnerships, which provide the Company income tax credits, and in a few small business investment companies. As of March 31, 2012, the Company had commitments to contribute capital to these entities totaling $6.7 million.

Legal Matters

        In the ordinary course of our business, we are party to various legal actions, which we believe are incidental to the operation of our business. The outcome of such legal actions and the timing of ultimate resolution are inherently difficult to predict. In the opinion of management, based upon information currently available to us, any resulting liability, in addition to amounts already accrued, would not have a material adverse effect on the Company's financial statements of operations.

NOTE 10—FAIR VALUE MEASUREMENTS

        ASC 820, "Fair Value Measurement," defines fair value, establishes a framework for measuring fair value including a three-level valuation hierarchy, and expands disclosures about fair value measurements. Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date reflecting assumptions that a market participant would use when pricing an asset or liability. The hierarchy uses three levels of inputs to measure the fair value of assets and liabilities as follows:

•

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets.

•

Level 2: Observable inputs other than Level 1, including quoted prices for similar assets and liabilities in active markets, quoted prices in less active markets, or other observable inputs that can be corroborated by observable market data, either directly or indirectly, for substantially the full term of the financial instrument. This category generally includes U.S. government and agency securities.

•

Level 3: Inputs to a valuation methodology that are unobservable, supported by little or no market activity, and significant to the fair value measurement. These valuation methodologies generally include pricing models, discounted cash flow models, or a determination of fair value that requires significant management judgment or estimation. This category includes our covered private label collateralized mortgage obligations ("CMOs"), which we refer to as private label CMOs.

        We use fair value to measure certain assets on a recurring basis, primarily securities available-for-sale; we have no liabilities being measured at fair value. For assets measured at the lower

of cost or fair value, the fair value measurement criteria may or may not be met during a reporting period and such measurements are therefore considered "nonrecurring" for purposes of disclosing our fair value measurements. Fair value is used on a nonrecurring basis to adjust carrying values for impaired loans and other real estate owned and also to record impairment on certain assets, such as goodwill, core deposit intangibles and other long-lived assets. There were no transfers of assets between Level 1 and Level 2 of the fair value hierarchy during the three months ended March 31, 2012. The following table presents information on the assets measured and recorded at fair value on a recurring basis as of the date indicated:

        The following is a description of the valuation methodologies used to measure our assets recorded at fair value (under ASC Topic 820) and for estimating fair value for financial instruments not recorded at fair value (under ASC Topic 825).

        Cash and due from banks.    The carrying amount is assumed to be the fair value because of the liquidity of these instruments.

        Interest-earning deposits in financial institutions.    The carrying amount is assumed to be the fair value given the short-term nature of these deposits.

        Securities available-for-sale.    Securities available-for-sale are measured and carried at fair value on a recurring basis. Unrealized gains and losses on available-for-sale securities are reported as a component of accumulated other comprehensive income on the condensed consolidated balance sheets. See Note 4,Investment Securities, for further information on unrealized gains and losses on securities available-for-sale.

        Fair value for securities categorized as Level 1, which are primarily equity securities, are based on readily available quoted prices. In determining the fair value of the securities categorized as Level 2, we obtain a report from a nationally recognized broker-dealer detailing the fair value of each investment security we hold as of each reporting date. The broker-dealer uses observable market information to value our securities, with the primary source being a nationally recognized pricing service. We review the market prices provided by the broker-dealer for our securities for reasonableness based on our understanding of the marketplace and we consider any credit issues related to the securities. As we have not made any adjustments to the market quotes provided to us and they are based on observable market data, they have been categorized as Level 2 within the fair value hierarchy.

        Our private label CMOs are categorized as Level 3 due in part to the inactive market for such securities. There is a wide range of prices quoted for private label CMOs among independent third party pricing services and this range reflects the significant judgment being exercised over the assumptions and variables that determine the pricing of such securities. We consider this subjectivity to

34

PACWEST BANCORP AND SUBSIDIARIES

Notes to Condensed Consolidated Financial Statements (Continued)

NOTE 10—FAIR VALUE MEASUREMENTS (Continued)

be a significant unobservable input and have concluded the private label CMOs should be categorized as a Level 3 measured asset. Our fair value estimate was based on prices provided to us by a nationally recognized pricing service which we also use to determine the fair value of the majority of our securities portfolio. We determined the reasonableness of the fair values by reviewing assumptions at the individual security level about prepayment, default expectations, estimated severity loss factors, and discount rates, all of which are not directly observable in the market. Significant increases (decreases) in default expectations, severity loss factors, or discount rates, which occur all together or in isolation, would result in lower (higher) fair value measurements.

        FHLB stock.    The fair value of FHLB stock is based on our recorded investment. FHLB stock is held at par value consistent with the value at which the FHLB has repurchased shares from its members during the first quarter of 2012. In January 2009, the FHLB announced that it had suspended excess FHLB stock redemptions and dividend payments. Since this announcement, the FHLB has declared and paid cash dividends in 2010, 2011 and 2012, though at rates less than those paid in the past, and repurchased certain amounts of our excess stock. As a result of these actions, we evaluated the carrying value of our FHLB stock investment. Based on the FHLB's most recent publicly available financial results, its capital position and its bond ratings, we concluded such investment was not impaired at March 31, 2012.

        Non-covered loans and leases.    As non-covered loans and leases are not measured at fair value, the following discussion relates to estimating the fair value disclosures under ASC Topic 825. Fair values are estimated for portfolios of loans and leases with similar financial characteristics. Loans are segregated by type and further segmented into fixed and adjustable rate interest terms and by credit risk categories. The fair value estimates do not take into consideration the value of the loan portfolio in the event the loans are sold outside the parameters of normal operating activities. The fair value of performing fixed rate loans is estimated by discounting scheduled cash flows through the estimated maturity using estimated market prepayment speeds. The fair value of equipment leases is estimated by discounting scheduled lease and expected lease residual cash flows over their remaining term. The estimated market discount rates used for performing fixed rate loans and equipment leases are the Company's current offering rates for comparable instruments with similar terms. The fair value of performing adjustable rate loans is estimated by discounting scheduled cash flows through the next repricing date. As these loans reprice frequently at market rates and the credit risk is not considered to be greater than normal, the market value is typically close to the carrying amount of these loans.

        Non-covered impaired loans.    Nonaccrual loans and performing restructured loans are considered impaired for reporting purposes and are measured and recorded at fair value on a non-recurring basis. Non-covered nonaccrual loans with an unpaid principal balance over $250,000 and all performing restructured loans are reviewed individually for the amount of impairment, if any. Non-covered nonaccrual loans with an unpaid principal balance of $250,000 or less are evaluated for impairment collectively.

        To the extent a loan is collateral dependent, we measure such impaired loan based on the estimated fair value of the underlying collateral. The fair value of each loan's collateral is generally based on estimated market prices from an independently prepared appraisal, which is then adjusted for the cost related to liquidating such collateral; such valuation inputs result in a nonrecurring fair value measurement that is categorized as a Level 2 measurement.

35

NOTE 10—FAIR VALUE MEASUREMENTS (Continued)

        When adjustments are made to an appraised value to reflect various factors such as the age of the appraisal or known changes in the market or the collateral, such valuation inputs are considered unobservable and the fair value measurement is categorized as a Level 3 measurement. The impaired loans categorized as Level 3 also include unsecured loans and other secured loans whose fair values are based significantly on unobservable inputs such as the strength of a guarantor, including an SBA government guarantee, cash flows discounted at the effective loan rate, and management's judgment.

        The non-covered impaired loan balances shown above represent those nonaccrual and restructured loans for which impairment was recognized during the three months ended March 31, 2012. The amounts shown as losses represent, for the loan balances shown, the impairment recognized during the three months ended March 31, 2012. Of the $48.2 million of nonaccrual loans at March 31, 2012, $5.5 million were written down to their fair values through charge-offs during the quarter.

        Other real estate owned.    The fair value of foreclosed real estate, both non-covered and covered, is generally based on estimated market prices from independently prepared current appraisals or negotiated sales prices with potential buyers, less estimated costs to sell; such valuation inputs result in a fair value measurement that is categorized as a Level 2 measurement on a nonrecurring basis. As a matter of policy, appraisals are required annually and may be updated more frequently as circumstances require in the opinion of management. The Level 2 measurement is based on appraisals obtained within the last 12 months and for which a write-down was recognized during the three months ended March 31, 2012.

        When a current appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value as a result of known changes in the market or the collateral and there is no observable market price, such valuation inputs result in a fair value measurement that is categorized as a Level 3 measurement. To the extent a negotiated sales price or reduced listing price represents a significant discount to an observable market price, such valuation input would result in a fair value measurement that is also considered a Level 3 measurement. The OREO losses disclosed are write-downs based on either a recent appraisal obtained after foreclosure or an accepted purchase offer by an independent third party received after foreclosure.

        SBA servicing asset.    In accordance with ASC Topic 860, "Transfers and Servicing," the SBA servicing asset, included in other assets in the condensed consolidated balance sheets, is carried at its implied fair value. The fair value of the servicing asset is estimated by discounting future cash flows using market-based discount rates and prepayment speeds. The discount rate is based on the current US Treasury yield curve, as published by the Department of the Treasury, plus a spread for the marketplace risk associated with these assets. We utilize estimated prepayment vectors using SBA prepayment information provided by Bloomberg for pools of similar assets to determine the timing of the cash flows. These nonrecurring valuation inputs are considered to be Level 3 inputs.

        Deposits.    Deposits are carried at historical cost. The fair value of deposits with no stated maturity, such as noninterest bearing demand deposits, interest checking, money market, and savings accounts, is equal to the amount payable on demand as of the balance sheet date and considered Level 1. The fair value of time deposits is based on the discounted value of contractual cash flows and considered Level 2. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. No value has been separately assigned to the Company's long-term relationships with its deposit customers, such as a core deposit intangible.

36

(Unaudited)

NOTE 10—FAIR VALUE MEASUREMENTS (Continued)

        Borrowings.    Borrowings are carried at amortized cost. The fair value of overnight FHLB advances is equal to the carrying value and considered Level 1. The fair value of fixed rate borrowings is calculated by discounting scheduled cash flows through the estimated maturity dates or call dates, if applicable, using estimated market discount rates that reflect current rates offered for borrowings with similar remaining maturities and characteristics.

        Subordinated debentures.    Subordinated debentures are carried at amortized cost. The fair value of subordinated debentures with variable rates is deemed to be the carrying value.

        Commitments to extend credit and standby letters of credit.    The majority of our commitments to extend credit carry current market interest rates if converted to loans. Because these commitments are generally unassignable by either the borrower or us, they only have value to the borrower and us. The estimated fair value approximates the recorded deferred fee amounts and is not disclosed as it is not material.

Limitations

        Fair value estimates are made at a specific point in time and are based on relevant market information and information about the financial instrument. These estimates do not reflect income taxes or any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument. Because no market exists for a portion of the Company's financial instruments, fair value estimates are based on what management believes to be conservative judgments regarding expected future cash flows, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimated fair values are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Since the fair values have been estimated as of March 31, 2012, the amounts that will actually be realized or paid at settlement or maturity of the instruments could be significantly different.

Restricted Stock

        At March 31, 2012, there were outstanding 767,760 shares of unvested time-based restricted common stock and 850,000 shares of unvested performance-based restricted common stock. The awarded shares of time-based restricted common stock vest over a service period of three to five years from the date of the grant. The awarded shares of performance-based restricted common stock vest in full on the date the Compensation, Nominating and Governance, or CNG, Committee of the Board of Directors, as Administrator of the Company's 2003 Stock Incentive Plan, or the 2003 Plan, determines that the Company achieved certain financial goals established by the CNG Committee as set forth in the grant documents. Both time-based and performance-based restricted common stock vest immediately upon a change in control of the Company as defined in the 2003 Plan and upon death of the employee.

        Compensation expense related to time-based restricted stock awards is based on the fair value of the underlying stock on the award date and is recognized over the vesting period using the straight-line

method. Restricted stock amortization totaled $1.6 million, $1.4 million and $2.0 million for the three months ended March 31, 2012, December 31, 2011, and March 31, 2011, respectively. Such amounts are included in compensation expense on the accompanying condensed consolidated statements of earnings.

        Currently no compensation expense is being recognized for any performance-based restricted stock awards as management has concluded that it is improbable that the respective financial targets for any outstanding performance-based restricted stock awards will be met. If and when the attainment of such financial targets is deemed probable in future periods, a catch-up adjustment will be recorded and amortization of such performance-based restricted stock will begin again. The total amount of unrecognized compensation expense related to all performance-based restricted stock for which amortization was suspended or has not commenced totaled $33.8 million at March 31, 2012 as presented in the following table.

	March 31, 2012

        The Company's 2003 Plan permits stock based compensation awards to officers, directors, key employees and consultants. As of March 31, 2012, the 2003 Plan authorized grants of stock-based compensation instruments to purchase or issue up to 5,000,000 shares of authorized but unissued Company common stock, subject to adjustments provided by the 2003 Plan. As of March 31, 2012, there were 414,365 shares available for grant under the 2003 Plan.

NOTE 13—RECENTLY ISSUED ACCOUNTING STANDARDS

        In June 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2011-05, "Comprehensive Income (Topic 220): Presentation of Comprehensive Income." Under ASU 2011-05, an entity will have the option to present the components of net earnings and comprehensive income in either one or two consecutive financial statements. This standard eliminates the option in U.S. GAAP to present other comprehensive income in the statement of changes in equity. ASU 2011-05 should be applied retrospectively and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011 and early adoption was permitted. Adoption of this standard did not have a material effect on our financial statements. In December 2011, the FASB issued ASU 2011-12, "Deferral of the Effective Date for Amendments to the Presentation of Reclassification of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05." ASU 2011-12 defers the effective date of those changes in ASU 2011-05 that

NOTE 14—SUBSEQUENT EVENTS

Celtic Capital Corporation Acquisition

        On April 3, 2012, Pacific Western Bank completed the acquisition of Celtic Capital Corporation, or Celtic, an asset-based lending company based in Santa Monica, CA. Celtic focuses on providing asset-based loans to borrowers in the $5 million and under loan market in the United States. Pacific Western Bank acquired all of the capital stock of Celtic for $18 million in cash. Celtic's tangible net assets at March 31, 2012 on a pro forma basis totaled approximately $9 million and is subject to finalization of our fair value determination. The acquisition diversifies the Company's loan portfolio, expands the Company's product lines, and deploys excess liquidity into higher yielding assets.

        At April 3, 2012, Celtic had approximately $56 million in gross loans outstanding, with no loans on nonaccrual status. In addition, Pacific Western Bank assumed $47 million in outstanding debt, which was repaid on the closing date. The weighted average yield on Celtic's loan portfolio as of the acquisition date was approximately 18% and its weighted average remaining maturity was seven months.

        Celtic will operate under the name Celtic Capital Corporation as a subsidiary of Pacific Western Bank. Pacific Western has retained all 26 of Celtic's employees.

American Perspective Bank Acquisition Announcement

        On April 30, 2012, the Company announced that Pacific Western Bank had entered into a definitive agreement and plan of merger to acquire all of the outstanding common stock and restricted stock of American Perspective Bank ("American Perspective") for $58.1 million in cash, or $13.00 per share for each share of common stock of American Perspective. The purchase price represented a multiple of 1.32 times American Perspective's tangible book value at March 31, 2012.

        At March 31, 2012, American Perspective had $264 million in assets, two operating branches located in San Luis Obispo and Santa Maria, California, and a loan production office located in Paso Robles, California. American Perspective serves small-to-medium sized businesses and professionals through those locations. The addition of the two branches strengthens the Company's presence in the Central Coast region and the loan production office provides opportunity for expansion and additional growth in that region.

        For the first quarter of 2012, American Perspective earned $462,000, had a net interest margin of 4.16%, and an efficiency ratio of 60.7%. It had $185 million in average loans which yielded 6.13% and its interest-bearing deposit cost was 0.92%, with total cost of deposits of 0.76%.

        The board of directors of each company has approved this transaction. The acquisition of American Perspective by Pacific Western Bank is subject to customary conditions, including the approval of American Perspective's shareholders and bank regulatory authorities, and is expected to

NOTE 14—SUBSEQUENT EVENTS (Continued)

close in the third quarter of 2012. Immediately following the completion of the acquisition, it is anticipated that American Perspective will be merged with and into Pacific Western Bank.

Dividend Approval

        On May 10, 2012, the Company announced that the Board of Directors had declared a quarterly cash dividend of $0.18 per common share payable on May 31, 2012, to stockholders of record at the close of business on May 21, 2012.

Overview

        We are a bank holding company registered under the Bank Holding Company Act of 1956, as amended. Our principal business is to serve as the holding company for our subsidiary bank, Pacific Western Bank, which we refer to as Pacific Western or the Bank.

        Pacific Western is a full-service commercial bank offering a broad range of banking products and services including: accepting demand, money market, and time deposits; originating loans, including

42

commercial, real estate construction, SBA guaranteed and consumer loans; and providing other business-oriented products. Our operations are primarily located in Southern California extending from California's Central Coast to San Diego County; we also operate three banking offices in the San Francisco Bay area. The Bank focuses on conducting business with small to medium sized businesses in our marketplace and the owners and employees of those businesses. The majority of our loans are secured by the real estate collateral of such businesses. Our asset-based lending functions operate in Arizona, California, Texas, and the Pacific Northwest. Our equipment leasing function, added through the acquisition of Pacific Western Equipment Finance, or PWE Finance, (formerly Marquette Equipment Finance) on January 3, 2012, is based in Utah and has lease receivables in 45 states.

        Pacific Western competes actively for deposits, and emphasizes solicitation of noninterest-bearing deposits. In managing the top line of our business, we focus on loan growth, loan yield, deposit cost, and net interest margin, as net interest income, on a year-to-date basis, accounted for 95% of our net revenues (net interest income plus noninterest income).

        During the three months ended March 31, 2012, total assets decreased $80.1 million due to a lower balance in interest-earning deposits in financial institutions, offset by higher securities available-for-sale and higher loans and leases. During the first quarter, interest-earning deposits in financial institutions declined $169.0 million due to the purchase of PWE Finance for $35.0 million and the repayment of $128.7 million of its debt. Securities available-for-sale increased $54.5 million due to purchases of $134.5 million. The non-covered gross loan and lease portfolio increased $56.1 million due to the lease receivables gained in the PWE Finance acquisition. When the lease receivables from the PWE Finance acquisition are excluded, however, non-covered gross loans declined $97.7 million; such decline is centered in the real estate mortgage loan portfolio. The covered loan portfolio declined $42.7 million due to repayments and resolution activities. At March 31, 2012, non-covered gross loans and leases totaled $2.9 billion and the covered loan portfolio was $660.3 million.

        During the three months ended March 31, 2012, total deposits declined $20.8 million to $4.6 billion at March 31, 2012. Core deposits grew $26.5 million during the first quarter with increases of $99.9 million, $15.3 million, and $5.6 million in noninterest-bearing demand deposits, interest checking deposits and savings deposits, respectively, offset by a decline of $94.3 million in money market deposits. Core deposits totaled $3.6 billion, or 80% of total deposits, at March 31, 2012. Time deposits decreased $47.3 million during the first quarter to $920.6 million at March 31, 2012. Noninterest-bearing demand deposits were $1.8 billion at March 31, 2012 and represented 39% of total deposits at that date.

Celtic Capital Corporation Acquisition

        On April 3, 2012, Pacific Western Bank completed the acquisition of Celtic Capital Corporation, or Celtic, an asset-based lending company based in Santa Monica, CA. Celtic focuses on providing asset-based loans to borrowers in the $5 million and under loan market in the United States. Pacific Western Bank acquired all of the capital stock of Celtic for $18 million in cash. Celtic's tangible net assets at March 31, 2012 on a pro forma basis totaled approximately $9 million. The acquisition diversifies the Company's loan portfolio, expands the Company's product lines, and deploys excess liquidity into higher yielding assets.

        At April 3, 2012, Celtic had approximately $56 million in gross loans outstanding, with no loans on nonaccrual status. In addition, Pacific Western Bank assumed $47 million in outstanding debt, which was repaid on the closing date. The weighted average yield on Celtic's loan portfolio as of the acquisition date was approximately 18% and its weighted average remaining maturity was seven months.

        Celtic will operate under the name Celtic Capital Corporation as a subsidiary of Pacific Western Bank. Pacific Western has retained all 26 of Celtic's employees.

American Perspective Bank Acquisition Announcement

        On April 30, 2012, the Company announced that Pacific Western Bank had entered into a definitive agreement and plan of merger to acquire all of the outstanding common stock and restricted stock of American Perspective Bank ("American Perspective") for $58.1 million in cash, or $13.00 per share for each share of common stock of American Perspective. The purchase price represented a multiple of 1.32 times American Perspective's tangible book value at March 31, 2012.

        At March 31, 2012, American Perspective had $264 million in assets, two operating branches located in San Luis Obispo and Santa Maria, California, and a loan production office located in Paso Robles, California. American Perspective serves small-to-medium sized businesses and professionals through those locations. The addition of the two branches strengthens the Company's presence in the Central Coast region and the loan production office provides opportunity for expansion and additional growth in that region.

        For the first quarter of 2012, American Perspective earned $462,000, had a net interest margin of 4.16%, and an efficiency ratio of 60.7%. It had $185 million in average loans which yielded 6.13% and its interest-bearing deposit cost was 0.92%, with total cost of deposits of 0.76%.

        The board of directors of each company has approved this transaction. The acquisition of American Perspective by Pacific Western Bank is subject to customary conditions, including the approval of American Perspective's shareholders and bank regulatory authorities, and is expected to close in the third quarter of 2012. Immediately following the completion of the acquisition, it is anticipated that American Perspective will be merged with and into Pacific Western Bank.

Key Performance Indicators

        Among other factors, our operating results depend generally on the following key performance indicators:

The Level of Our Net Interest Income

        Net interest income is the excess of interest earned on our interest-earning assets over the interest paid on our interest-bearing liabilities. Net interest margin is net interest income expressed as a percentage of average interest-earning assets. A sustained low interest rate environment combined with low loan growth and high levels of marketplace liquidity may lower both our net interest income and net interest margin going forward.

        Our primary interest-earning assets are loans and investments. Our primary interest-bearing liabilities are deposits. We attribute our high net interest margin to our high level of noninterest-bearing deposits and low cost of deposits. While our deposit balances will fluctuate depending on deposit holders' perceptions of alternative yields available in the market, we attempt to minimize these variances by attracting a high percentage of noninterest-bearing deposits, which have no expectation of yield. At March 31, 2012, approximately 39% of our total deposits were noninterest-bearing.

Loan Growth

        We generally seek new lending opportunities in the $500,000 to $15 million range, try to limit loan maturities for commercial loans to one year, for construction loans up to 18 months, and for commercial real estate loans up to ten years, and to price lending products so as to preserve our interest spread and net interest margin. We sometimes encounter strong competition in pursuing lending opportunities such that potential borrowers obtain loans elsewhere at lower rates than those we offer. Our ability to make new loans is dependent on economic factors in our market area, borrower qualifications, competition, and liquidity, among other items. Loan growth remains tepid, as new loan volume is not replacing maturities. We attribute this to the competition for new and maturing loans

44

from money center banks, regional banks and community banks that operate in our market areas. Such competition centers on unreasonably low interest rates and unrestrictive loan terms. We continue to retain, however, maturing lending relationships that contribute positively to our profitability and net interest margin, and selectively add new loans that meet our credit and pricing standards.

        We have expanded our commercial loan portfolio through the January 3, 2012 acquisition of equipment leasing company PWE Finance and the April 3, 2012 acquisition of asset-based lender Celtic. As of March 31, 2012, PWE Finance had $167.7 million of leases and leases in process. As of April 3, 2012, Celtic had $56 million in gross loans. As previously mentioned, gross loans declined $97.7 million during the three months ended March 31, 2012, excluding the PWE Finance lease receivables, with the decline centered in real estate mortgage loans.

The Magnitude of Credit Losses

        We stress credit quality in originating and monitoring the loans we make and measure our success by the levels of our nonperforming assets, net charge-offs and allowance for credit losses. We maintain an allowance for credit losses on non-covered loans which is the sum of our allowance for loan losses and our reserve for unfunded loan commitments. Provisions for credit losses are charged to operations as and when needed for both on and off balance sheet credit exposure. Loans which are deemed uncollectible are charged off and deducted from the allowance for loan losses. Recoveries on loans previously charged off are added to the allowance for loan losses. The provision for credit losses on the non-covered loan portfolio was based on our allowance methodology and reflected net charge-offs, the levels and trends of nonaccrual and classified loans, and the migration of loans into various risk classifications. A provision for credit losses on the covered loan portfolio may be recorded to reflect decreases in expected cash flows on covered loans compared to those previously estimated.

        We regularly review our loans to determine whether there has been any deterioration in credit quality stemming from economic conditions or other factors which may affect collectibility of our loans. Changes in economic conditions, such as inflation, unemployment, increases in the general level of interest rates, declines in real estate values and negative conditions in borrowers' businesses could negatively impact our customers and cause us to adversely classify loans and increase portfolio loss factors. An increase in classified loans generally results in increased provisions for credit losses. Any deterioration in the real estate market may lead to increased provisions for credit losses because of our concentration in real estate loans.

The Level of Our Noninterest Expense

        Our noninterest expense includes fixed and controllable overhead, the major components of which are compensation, occupancy, data processing, and other professional services. It also includes costs that tend to vary based on the volume of activity, such as OREO expense. We measure success in controlling both fixed and variable costs through monitoring of the efficiency ratio. We calculate the base efficiency ratio by dividing noninterest expense by net revenues (the sum of net interest income plus noninterest income). We also calculate a non-GAAP measure called the "adjusted efficiency ratio." The adjusted efficiency ratio is calculated in the same manner as the base efficiency ratio except that noninterest income is reduced by FDIC loss sharing income and noninterest expense is reduced by OREO expenses and debt termination expense. During the three months ended March 31, 2012, the Company incurred $22.6 million of debt termination expense in connection with the prepayment of $225.0 million of fixed-rate term FHLB advances and the early redemption of $18.6 million in fixed-rate subordinated debentures; there was no similar debt termination expense in any other quarterly period presented. See calculations in "Results of Operations—Non-GAAP Measurements" contained herein.

45

        The consolidated base and adjusted efficiency ratios have been as follows:

Three Months Ended	Base Efficiency Ratio			Adjusted Efficiency Ratio
March 31, 2012		97.1	%		58.6	%
December 31, 2011		60.4	%		59.9	%
September 30, 2011		67.9	%		58.7	%
June 30, 2011		58.2	%		57.7	%
March 31, 2011		58.7	%		60.4	%

        The base efficiency ratio fluctuations shown in the above table result mostly from the volatility of FDIC loss sharing income and OREO expenses and, for the first quarter of 2012, from the debt termination expense. The adjusted efficiency ratio eliminates (a) the volatility of FDIC loss sharing income and OREO expenses and (b) debt termination expense and shows the trend in overhead-related noninterest expense relative to net revenues.

Critical Accounting Policies

        The Company's accounting policies are fundamental to understanding management's discussion and analysis of results of operations and financial condition. The Company has identified several policies as being critical because they require management to make particularly difficult, subjective and/or complex judgments about matters that are inherently uncertain and because of the likelihood that materially different amounts would be reported under different conditions or using different assumptions. These policies relate to the allowance for credit losses and the carrying values of intangible assets and deferred income tax assets. For further information, refer to our Annual Report on Form 10-K for the year ended December 31, 2011.

Non-GAAP Measurements

        Certain discussion in this Form 10-Q contains non-GAAP financial disclosures for tangible common equity, pre-credit, pre-debt termination and pre-tax earnings, and adjusted efficiency ratios. The Company uses certain non-GAAP financial measures to provide meaningful supplemental information regarding the Company's operational performance and to enhance investors' overall understanding of such financial performance. Given the use of tangible common equity amounts and ratio is prevalent among banking regulators, investors and analysts, we disclose our tangible common equity ratio in addition to the equity-to-assets ratio. Also, as analysts and investors view pre-credit, pre-debt termination and pre-tax earnings as an indicator of the Company's ability to absorb credit losses, we disclose this amount in addition to net earnings. The methodology of determining tangible common equity and pre-credit, pre-debt termination, and pre-tax earnings may differ among companies. We disclose the adjusted efficiency ratio as it eliminates (a) the volatility of FDIC loss sharing income and OREO expenses and (b) debt termination expense from the base efficiency ratio and shows the trend in overhead-related noninterest expense relative to net revenues.

        These non-GAAP financial measures are presented for supplemental informational purposes only for understanding the Company's operating results and should not be considered a substitute for financial information presented in accordance with United States generally accepted accounting principles ("GAAP"). The following table presents performance amounts and ratios in accordance with

First Quarter of 2012 Compared to Fourth Quarter of 2011

        Net earnings for the first quarter of 2012 were $5.3 million, or $0.14 per diluted share, compared to $13.9 million, or $0.38 per diluted share, for the fourth quarter of 2011. The $8.6 million decline in net earnings for the linked quarters was due mostly to $22.6 million of debt termination expense incurred on the prepayment of $225.0 million in fixed-rate term FHLB advances and the early redemption of $18.6 million in fixed-rate subordinated debentures. In addition, the provision for credit losses on non-covered loans declined $10.0 million and FDIC loss sharing income declined $6.2 million for the linked quarters.

First Quarter of 2012 Compared to First Quarter of 2011

        Net earnings for the first quarter of 2012 were $5.3 million, or $0.14 per diluted share, compared to net earnings of $10.7 million, or $0.29 per diluted share, for the first quarter of 2011. The $5.4 million decline in net earnings was due mostly to the $22.6 million debt termination expense incurred during the first quarter of 2012 and $2.4 million decline in FDIC loss sharing income, offset partially by a $17.8 million decrease in the provision for credit losses on non-covered loans.

Net Interest Income

        Net interest income, which is our principal source of revenue, represents the difference between interest earned on interest-earning assets and interest paid on interest-bearing liabilities. Net interest margin is net interest income expressed as a percentage of average interest-earning assets. Net interest income is affected by changes in both interest rates and the volume of average interest-earning assets and interest-bearing liabilities.

        The following tables present, for the periods indicated, the distribution of average assets, liabilities and stockholders' equity, as well as interest income and yields earned on average interest-earning assets and interest expense and rates paid on average interest-bearing liabilities:

        The net interest margin has been impacted by the accelerated accretion of purchase discounts on covered loan payoffs and loans being placed on or removed from nonaccrual status. The effects of such items on the net interest margin are shown in the following table for the periods indicated:

First Quarter of 2012 Compared to Fourth Quarter of 2011

        Net interest income was $67.7 million for the first quarter of 2012 compared to $63.8 million for the fourth quarter of 2011. The $3.9 million increase was due to a $3.1 million increase in loan and lease interest income; such increase is attributed to a higher yield on average loans and leases and due mainly to the yield earned on PWE Finance's lease portfolio. Contributing to the increase in interest income was a reduction in interest expense of $420,000 due to lower rates on all interest-bearing deposits and lower average time deposits.

        Our net interest margin for the first quarter of 2012 was 5.41%, an increase of 41 basis points from the 5.00% reported for the fourth quarter of 2011. This increase was due mostly to an increase in loan and lease yield as the first quarter includes income on $146.4 million of average lease receivables with a 12% yield. The addition of the lease portfolio increased the net interest margin approximately 25 basis points, assuming such excess liquidity would have otherwise been deployed in investment securities. In addition, the net interest margin is impacted by the accelerated accretion of discounts on covered loan payoffs which increased the margin 18 basis points for the linked quarters. Average outstanding loans and leases were unchanged quarter over quarter.

        The yield on average loans and leases increased 44 basis points to 7.31% for the first quarter of 2012 from 6.87% for the fourth quarter of 2011. The addition of PWE Finance's lease portfolio increased the loan and lease yield 21 basis points and the accelerated accretion of discounts on covered loan payoffs increased the loan and lease yield 29 basis points.

        All-in deposit cost declined 4 basis points to 0.32%. The cost of interest-bearing deposits declined 6 basis points to 0.51% due to lower rates on interest-bearing deposits and a decline in average time deposits, which shifted the mix of deposits to lower cost interest checking, money market and savings deposits. Average time deposits declined $61.4 million during the first quarter of 2012 compared to the fourth quarter of 2011. The cost of total interest-bearing liabilities declined 3 basis points to 0.85% for the first quarter of 2012.

        In March 2012, the Company prepaid $18.6 million in fixed-rate subordinated debentures and $225.0 million in fixed-rate term FHLB advances. The resulting debt termination expense incurred was $22.6 million; the interest expense savings is estimated to be $6.8 million for the remainder of 2012 and $8.8 million annually through 2016. The Company used a combination of excess cash and collateralized overnight FHLB advances to repay these debt instruments. These repayments are expected to expand the net interest margin beginning in the second quarter by approximately 25 basis points from a combination of lower average earning assets and the reduced borrowing costs.

51

First Quarter of 2012 Compared to First Quarter of 2011

        Net interest income was $67.7 million for the first quarter of 2012 compared to $65.7 million for the first quarter of 2011. The $2.0 million increase was due primarily to a $2.4 million decline in interest expense on deposits; such decline was due mainly to lower rates on all interest-bearing deposits and lower average time deposits. Contributing to the increase in net interest income was a $1.8 million increase in interest income on investment securities attributable to a higher average balance due to purchases, offset by a lower yield. Offsetting these factors which increased net interest income was a decline in interest income on loans of $2.0 million due to a lower average balance, offset by an increase in yield.

        The net interest margin grew 7 basis points to 5.41% for the first quarter of 2012 compared to 5.34% for the same period last year, due mostly to the decline in interest expense on deposits. The yield on average loans grew 53 basis points to 7.31% for the first quarter of 2012 from 6.78% from the first quarter of 2011, due to the addition of PWE Finance's higher yielding lease portfolio and the accelerated accretion of purchase discount on covered loan payoffs recorded in the first quarter of 2012.

        All-in deposit cost declined 20 basis points to 0.32%. The cost of interest-bearing deposits declined 28 basis points to 0.51% due to lower rates on interest-bearing deposits and a decline in average time deposits, which shifted the mix of deposits to lower cost interest checking, money market and savings deposits. Average time deposits declined $225.0 million during the first quarter of 2012 compared to the same period last year. Average noninterest-bearing demand deposits increased $136.3 million and represented 38% of total average deposits for the first quarter of 2012 compared to 34% for the first quarter of 2011. The cost of total interest-bearing liabilities declined 21 basis points to 0.85% for the first quarter of 2012.

Allowance for credit losses to non-covered nonaccrual loans and leases		169.7	%		161.0	%		135.6	%

        Provisions for credit losses are charged to earnings as and when needed for both on and off balance sheet credit exposures. We have a provision for credit losses on our non-covered loans and

52

leases and a provision for credit losses on our covered loans. The provision for credit losses on our non-covered loans and leases is based on our allowance methodology and is an expense, or contra-expense, that, in our judgment, is required to maintain the adequacy of the allowance for loan and lease losses and the reserve for unfunded loan commitments. Our allowance methodology reflects net charge-offs, the levels and trends of nonaccrual and classified loans and leases, and the migration of loans and leases into various risk classifications. The provision for credit losses on our covered loans reflects decreases in expected cash flows on covered loans compared to those previously estimated.

        The Company recorded a negative provision for credit losses of $6.1 million in the first quarter of 2012, compared to a provision for credit losses of $4.1 million for the fourth quarter of 2011 and $10.7 million for the first quarter of 2011. The provision related to non-covered loans was a $10.0 million negative provision for the first quarter of 2012; this compares to a zero provision for the fourth quarter of 2011 and a $7.8 million provision for the first quarter of 2011. Net non-covered loan charge-offs were $2.0 million for the first quarter of 2012; this compares to $2.8 million for the fourth quarter of 2011 and $7.9 million for the first quarter of 2011.

        The declining trend in credit loss provisions results from lower non-covered loan balances and improving credit quality, evidenced by lower nonaccrual and classified loan balances. Gross non-covered loans and leases declined $97.7 million when the acquired PWE Finance lease receivables are excluded. During the first quarter of 2012, nonaccrual loans and leases declined by $10.1 million, or 17%, to $48.2 million and classified loans and leases decreased by $39.7 million, or 21%, to $145.9 million. Nonaccrual loans and leases totaled $48.2 million, $58.3 million, and $76.8 million at March 31, 2012, December 31, 2011, and March 31, 2011, respectively. Classified loans and leases were $145.9 million, $185.6 million, and $207.0 million at March 31, 2012, December 31, 2011, and March 31, 2011, respectively.

        The allowance for credit losses on non-covered loans was $81.7 million as of March 31, 2012 and represented 2.85% of the non-covered loan balances at that date. This compares to an allowance for credit losses on non-covered loans of $93.8 million, or 3.34% of non-covered loans, as of December 31, 2011 and an allowance for credit losses on non-covered loans of $104.2 million, or 3.41% of non-covered loans, as of March 31, 2011.

        During the first quarter of 2012, we recorded a $3.9 million provision for credit losses on the covered loan portfolio based on a current analysis of covered loans, which indicated a decrease in expected cash flows from previous estimates. The provisions for credit losses on covered loans for the fourth quarter of 2011 and first quarter of 2011 were $4.1 million and $2.9 million, respectively. The FDIC absorbs 80% of losses on covered loans under the terms of our loss-sharing agreement.

        Increased provisions for credit losses may be required in the future based on loan and unfunded commitment growth, the effect changes in economic conditions, such as inflation, unemployment, market interest rate levels, and real estate values, may have on the ability of our borrowers to repay their loans, and other negative conditions specific to our borrowers' businesses.

First Quarter of 2012 Compared to Fourth Quarter of 2011 and First Quarter of 2011

        Noninterest income for the first quarter of 2012 totaled $3.3 million compared to $8.3 million for the fourth quarter of 2011 and $4.8 million for the first quarter of 2011. The $5.0 million decline for the first quarter of 2012 compared to the prior quarter was due to lower net FDIC loss sharing income of $6.2 million, offset partially by a higher gain on sale of leases of $990,000, the latter item relating to PWE Finance's operations. The first quarter of 2012 includes net FDIC loss sharing expense of $3.6 million due to a higher level of write-downs and amortization of the FDIC loss sharing asset as the estimated amount of losses collectible from the FDIC decreased; this compares to net FDIC loss sharing income of $2.7 million in the fourth quarter of 2011 and net FDIC loss sharing expense of $1.2 million for the first quarter of 2011.

        The $1.5 million decline in noninterest income for the first quarter of 2012 compared to the same period last year was due primarily to a $2.4 million increase in net FDIC loss sharing expense, offset partially by a higher gain on sale of leases of $990,000 relating to PWE Finance's operations. The increase in net FDIC loss sharing expense reflects a higher level of write-downs and amortization of the FDIC loss sharing asset, offset partially by lower levels of recoveries of loans previously charged off and gains on sale of covered OREO.

First Quarter of 2012 Compared to Fourth Quarter of 2011

        Noninterest expense increased $25.4 million to $68.9 million during the first quarter of 2012 compared to $43.5 million for the fourth quarter of 2011. The increase was due mostly to $22.6 million in debt termination expense for the early repayment of $225.0 million of fixed-rate term FHLB advances and $18.6 million of fixed-rate subordinated debentures. Excluding the debt termination expense, noninterest expense increased $2.8 million, of which $2.3 million relates to the PWE Finance acquisition which closed on January 3, 2012. Compensation cost increased $3.5 million quarter-over-quarter when the fourth quarter of 2011 severance cost of $885,000 is excluded. The leasing company acquisition accounted for $1.6 million of that increase. The remainder of the

55

compensation increase was attributable to higher payroll taxes due to the start of the new year and higher incentive compensation. Covered OREO costs increased due to higher write-downs of $1.3 million offset by higher gains on sales of $692,000. These increases were offset by declines in other professional services, insurance and assessments, and acquisition costs of approximately $1.0 million in total. Other professional services declined due to lower legal costs and insurance and assessments are lower as a result of the revised deposit insurance assessment formula.

        Noninterest expense includes the following non-cash items: (a) amortization of time-based restricted stock, which is included in compensation, and (b) intangible asset amortization. Amortization of restricted stock totaled $1.6 million, $1.4 million, and $2.0 million for the first quarter of 2012, fourth quarter of 2011, and first quarter of 2011, respectively. Intangible asset amortization totaled $1.7 million, $1.8 million, and $2.3 million for the first quarter of 2012, fourth quarter of 2011, and first quarter of 2011, respectively.

First Quarter of 2012 Compared to First Quarter of 2011

        Noninterest expense grew $27.5 million for the first quarter of 2012 compared to the same period of 2011 due mostly to the $22.6 million in debt termination expense incurred during the first quarter of 2012. Excluding the debt termination expense, noninterest expense increased $4.9 million, of which $2.3 million relates to the PWE Finance acquisition which closed on January 3, 2012. Covered OREO costs increased $3.4 million due mainly to higher write-downs of $1.3 million and lower gains on sales of $2.3 million. Compensation cost increased $2.3 million, of which the leasing company acquisition accounted for $1.6 million, with the remainder due primarily to higher incentive compensation.

Income Taxes

        The effective tax rate for the first quarter of 2012 was 35.2% compared to 43.2% for the fourth quarter of 2011 and 42.0% in the first quarter of 2011. The lower rate in the first quarter of 2012 resulted from a higher proportion of tax credits and tax exempt income to pre-tax income. The Company operates primarily in the Federal and California jurisdictions and the blended statutory tax rate for Federal and California is 42%.

        The loans acquired in the Los Padres and Affinity acquisitions are covered by loss sharing agreements with the FDIC and we will be reimbursed for a substantial portion of any future losses. Through March 31, 2012, gross losses for Los Padres covered assets totaled $49.1 million and gross losses for Affinity covered assets totaled $148.5 million. Of this total of $197.6 million in losses, we have received payment from the FDIC of $152.7 million, which represented 80% of our losses, and we expect to receive $5.4 million for recently submitted claims.

        Under the terms of the Los Padres loss sharing agreement, the FDIC will absorb 80% of losses and receive 80% of loss recoveries on the covered assets. The Los Padres loss sharing provisions expire in the third quarters of 2015 and 2020 for non-single family and single family covered assets, respectively, while the related loss recovery provisions expire in the third quarters of 2018 and 2020, respectively.

        Under the terms of the Affinity loss sharing agreement, the FDIC will (a) absorb 80% of losses and receive 80% of loss recoveries on the first $234 million of losses on covered assets and (b) absorb 95% of losses and receive 95% of loss recoveries on covered assets exceeding $234 million. The Affinity loss sharing provisions expire in the third quarters of 2014 and 2019 for non-single family covered assets and single family covered assets, respectively, while the related loss recovery provisions expire in the third quarters of 2017 and 2019, respectively.

Allowance for Credit Losses on Non-Covered Loans and Leases

        The allowance for credit losses on non-covered loans and leases is the combination of the allowance for loan and lease losses and the reserve for unfunded loan commitments. The allowance for credit losses on non-covered loans and leases relates only to loans and leases which are not subject to loss sharing agreements with the FDIC. The allowance for loan and lease losses is reported as a reduction of outstanding loan and lease balances and the reserve for unfunded loan commitments is included within other liabilities. Generally, as loans are funded, the amount of the commitment reserve applicable to such funded loans is transferred from the reserve for unfunded loan commitments to the allowance for loan and lease losses based on our allowance methodology. The following discussion is for non-covered loans and leases and the allowance for credit losses thereon. Refer to "Balance Sheet Analysis—Allowance for Credit Losses on Covered Loans" for the policy on covered loans.

        At March 31, 2012, the allowance for credit losses on non-covered loans and leases totaled $81.7 million, a $12.1 million decrease from the allowance at December 31, 2011, and was comprised of the allowance for loan and lease losses of $74.7 million and the reserve for unfunded loan commitments of $7.0 million. During the three months ended March 31, 2012, the Company recorded $2.0 million in net charge-offs and a negative provision for credit losses of $10.0 million.

        The allowance for loan and lease losses is maintained at a level deemed appropriate by management to adequately provide for known and inherent risks in the loan and lease portfolio and other extensions of credit at the balance sheet date. The allowance is based upon a continuing review of the portfolio, past loan loss experience, current economic conditions which may affect the borrowers' ability to pay, and the underlying collateral value of the loans. Loans and leases which are deemed to be uncollectible are charged off and deducted from the allowance. The provision for loan and lease losses and recoveries on loans and leases previously charged off are added to the allowance.

        The methodology we use to estimate the amount of our allowance for credit losses is based on both objective and subjective criteria. While some criteria are formula driven, other criteria are subjective inputs included to capture environmental and general economic risk elements which may trigger losses in the loan and lease portfolios, and to account for the varying levels of credit quality in the loan and lease portfolios of the entities we have acquired that have not yet been captured in our objective loss factors.

        Specifically, our allowance methodology contains three key elements: (i) amounts based on specific evaluations of impaired loans and leases; (ii) amounts of estimated losses on several pools of loans categorized by risk rating and loan type; and (iii) amounts for environmental and general economic factors that indicate probable losses were incurred but were not captured through the other elements of our allowance process.

        Impaired loans and leases are identified at each reporting date based on certain criteria and the majority of which are individually reviewed for impairment. Non-covered nonaccrual loans and leases with an unpaid principal balance over $250,000 and all performing restructured loans are reviewed individually for the amount of impairment, if any. Non-covered nonaccrual loans and leases with an unpaid principal balance of $250,000 or less are evaluated for impairment collectively. A loan or lease is considered impaired when it is probable that a creditor will be unable to collect all amounts due according to the original contractual terms of the agreement. We measure impairment of a loan based upon the fair value of the loan's collateral if the loan is collateral-dependent or the present value of cash flows, discounted at the loan's effective interest rate, if the loan is not collateral-dependent. 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. We measure impairment of a lease based upon the present value of the scheduled lease and lease residual cash flows, discounted at the lease's effective interest rate. Increased charge-offs or additions to specific reserves generally result in increased provisions for credit losses.

64

        Our loan and lease portfolio, excluding impaired loans and leases which are evaluated individually, is categorized into several pools for purposes of determining allowance amounts by pool. The pools we currently evaluate are: commercial real estate construction, residential real estate construction, SBA real estate, hospitality real estate, real estate other, commercial collateralized, commercial unsecured, SBA commercial, consumer, foreign, asset-based and leasing (due to the PWE Finance acquisition in January 2012). Within these loan pools, we then evaluate loans not adversely classified, which we refer to as "pass" credits, separately from adversely classified loans. The adversely classified loans are further grouped into three credit risk rating categories: "special mention," "substandard" and "doubtful," which we define as follows:

•

Special Mention: Loans and leases classified as special mention have a potential weakness that requires management's attention. If not addressed, these potential weaknesses may result in further deterioration in the borrower's ability to repay the loan.

•

Substandard: Loans and leases classified as substandard have a well-defined weakness or weaknesses that jeopardize the collection of the debt. They are characterized by the possibility that we will sustain some loss if the weaknesses are not corrected.

•

Doubtful: Loans and leases classified as doubtful have all the weaknesses as those classified as Substandard, with the additional trait that the weaknesses make collection or repayment in full highly questionable and improbable.

        In addition, we may refer to the loans and leases classified as "substandard" and "doubtful" together as "criticized loans." For additional information on classified loans, see Note 5,Loans and Lease, in the Notes to Consolidated Financial Statements (Unaudited) contained in "Item 1. Condensed Consolidated Financial Statements (Unaudited)."

        The allowance amounts for "pass" rated loans and leases and those loans and leases adversely classified, which are not reviewed individually, are determined using historical loss rates developed through migration analysis. The migration analysis is updated quarterly based on historic losses and movement of loans between ratings. As a result of this migration analysis and its quarterly updating, the decreases we experienced in both charge-offs and adverse classifications generally resulted in lower loss factors.

        Finally, in order to ensure our allowance methodology is incorporating recent trends and economic conditions, we apply environmental and general economic factors to our allowance methodology including: credit concentrations; delinquency trends; economic and business conditions; the quality of lending management and staff; lending policies and procedures; loss and recovery trends; nature and volume of the portfolio; nonaccrual and problem loan trends; usage trends of unfunded commitments; and other adjustments for items not covered by other factors.

        Management believes that the allowance for loan and lease losses is adequate and appropriate for the known and inherent risks in our non-covered loan portfolio. In making its evaluation, management considers certain quantitative and qualitative factors including the Company's historical loss experience, the volume and type of lending conducted by the Company, the results of our credit review process, the levels of classified and criticized loans, the levels of impaired loans, including nonperforming loans performing restructured loans, regulatory policies, general economic conditions, underlying collateral values, and other factors regarding collectibility and impairment. To the extent we experience, for example, increased levels of documentation deficiencies, adverse changes in collateral values, or negative changes in economic and business conditions which adversely affect our borrowers, our classified loans may increase. Higher levels of classified loans generally result in higher allowances for loan losses.

        We recognize that the determination of the allowance for loan and lease losses is sensitive to the assigned credit risk ratings and inherent loss rates at any given point in time. Therefore, we perform

65

sensitivity analyses to provide insight regarding the impact adverse changes in credit risk ratings may have on our allowance for loan losses. The sensitivity analyses have inherent limitations and are based on various assumptions as of a point in time and, accordingly, it is not necessarily representative of the impact loan risk rating changes may have on the allowance for loan losses.

        At March 31, 2012, in the event that 1% of our non-covered loans and leases were downgraded one credit risk rating category for each category (e.g., 1% of the "pass" category moved to the "special mention" category, 1% of the "special mention" category moved to "substandard" category, and 1% of the "substandard" category moved to the "doubtful" category within our current allowance methodology), the allowance for credit losses would have increased by approximately $1.5 million. In the event that 5% of our non-covered loans and leases were downgraded one credit risk category, the allowance for credit losses would increase by approximately $7.6 million. Given current processes employed by the Company, management believes that the credit risk ratings and inherent loss rates currently assigned are appropriate. It is possible that others, given the same information, may at any point in time reach different conclusions that could be significant to the Company's financial statements. In addition, current credit risk ratings are subject to change as we continue to review loans within our portfolio and as our borrowers are impacted by economic trends within their market areas.

        Although we have established an allowance for loan and lease losses that we consider adequate, there can be no assurance that the established allowance for loan and lease losses will be sufficient to offset losses on loans and leases in the future. Management also believes that the reserve for unfunded loan commitments is adequate. In making this determination, we use the same methodology for the reserve for unfunded loan commitments as we do for the allowance for loan and lease losses and consider the same quantitative and qualitative factors, as well as an estimate of the probability of advances of the commitments correlated to their credit risk rating.

Allowance for Credit Losses on Covered Loans

        The loans acquired in the Los Padres and Affinity acquisitions are covered by loss sharing agreements with the FDIC and we will be reimbursed for a substantial portion of any future losses. Under the terms of the Los Padres loss sharing agreement, the FDIC will absorb 80% of losses and receive 80% of loss recoveries on the covered assets. The loss sharing provisions are in effect for 10 years for single family covered assets and 5 years for commercial (non-single family) covered assets from the August 20, 2010 acquisition date. The loss recovery provisions are in effect for 10 years for single family assets and 8 years for commercial (non-single family) assets from the acquisition date. Under the terms of the Affinity loss sharing agreement, the FDIC will absorb 80% of losses and receive 80% of loss recoveries on the first $234 million of losses on covered assets and absorb 95% of losses and receive 95% of loss recoveries on covered assets exceeding the $234 million threshold. The loss sharing provisions are in effect for 10 years for residential loans and 5 years for commercial assets (non-residential loans, OREO and certain securities) from the August 28, 2009 acquisition date. The loss recovery provisions are in effect for 10 years for residential loans and 8 years for commercial assets from the acquisition date.

        We evaluated the acquired covered loans and elected to account for them under Accounting Standards Codification ("ASC") Subtopic 310-30, "Loans and Debt Securities Acquired with Deteriorated Credit Quality" ("ASC 310-30"), which we refer to as acquired impaired loan accounting.

        The covered loans are subject to our internal and external credit review. If deterioration in the expected cash flows results in a reserve requirement, a provision for credit losses is charged to earnings without regard to the FDIC loss sharing agreement. The portion of the estimated loss reimbursable from the FDIC is recorded in FDIC loss sharing income and increases the FDIC loss sharing asset. For acquired impaired loans, the allowance for loan losses is measured at the end of each financial reporting period based on expected cash flows. Decreases in the amount and changes in the timing of expected cash flows on the acquired impaired loans as of the financial reporting date compared to those previously estimated are usually recognized by recording a provision for credit losses on such covered loans.

        Certain home equity lines of credit acquired in the Los Padres acquisition are not eligible for acquired impaired loan accounting and are therefore accounted for as performing acquired loans. Such acquired loans were initially recorded at a discount and are subject to our quarterly allowance for credit losses methodology. We record a provision for such loan losses only when the reserve requirement exceeds any remaining credit discount on these covered loans.

Nonperforming assets ratio is calculated as nonperforming assets divided by the sum of total loans and leases and OREO.

        Non-covered nonperforming assets include non-covered nonaccrual loans and leases and non-covered OREO and totaled $94.4 million at March 31, 2012 compared to $106.7 million at December 31, 2011. The $12.3 million decline in non-covered nonperforming assets is due to reductions of $10.1 million and $2.2 million in nonaccrual loans and leases and OREO, respectively. The non-covered nonperforming assets ratio decreased to 3.24% at March 31, 2012 from 3.73% at December 31, 2011.

Nonaccrual Loans and Leases

        The $10.1 million decline in non-covered nonaccrual loans and leases during the first quarter was attributable to (a) foreclosures of $1.8 million, (b) other reductions, payoffs and returns to accrual status of $12.1 million, (c) charge-offs of $2.5 million, and (d) additions of $6.3 million.

OREO

        Non-covered OREO declined $2.2 million during the first quarter of 2012 due mainly to sales of $3.9 million, offset partially by foreclosures of $1.8 million.

        The following table presents the components of non-covered OREO by property type as of the dates indicated:

Performing Restructured Loans

        Non-covered performing restructured loans declined by $6.7 million during the first quarter of 2012 to $110.1 million at March 31, 2012. The decline was attributable primarily to $13.4 million in loans that were paid off and $2.2 million in loans transferred to nonaccrual status, offset partially by one loan for $9.4 million that was transferred from nonaccrual status. At March 31, 2012, we had

71

$81.3 million in real estate mortgage loans, $24.4 million in real estate construction loans, and $4.4 million in commercial loans that were accruing interest under the terms of troubled debt restructurings.

        The majority of the performing restructured loans was on accrual status prior to the loan modifications and has remained on accrual status after the loan modifications due to the borrowers making payments before and after the restructurings. In these circumstances, generally, a borrower may have had a fixed rate loan that they continued to repay, but may be having cash flow difficulties. In an effort to work with certain borrowers, we have agreed to interest rate reductions to reflect the lower market interest rate environment and/or interest-only payments for a period of time. In these cases, we do not forgive principal or extend the maturity date as part of the loan modification. As a result of the current economic environment in our market areas, we anticipate loan restructurings to continue.

Covered Nonperforming Assets

        Loans accounted for under ASC 310-30 are generally considered accruing and performing loans as the loans accrete interest income over the estimated life of the loan when cash flows are reasonably estimable. Accordingly, acquired impaired loans that are contractually past due are still considered to be accruing and performing loans. If the timing and amount of future cash flows is not reasonably estimable, the loans may be classified as nonaccrual loans and interest income is not recognized until the timing and amount of future cash flows can be reasonably estimated.

        The following table presents a summary of covered loans that would be considered nonaccrual except for the accounting requirements regarding acquired impaired loans and other real estate owned covered by the loss sharing agreement ("covered nonaccrual loans" and "covered OREO"; collectively, "covered nonperforming assets") as of the dates indicated:

Loan Portfolio Risk Elements

        The negative trends throughout the Southern California economy have affected certain industries and collateral types more than others. Our real estate loan portfolio is predominantly commercial and as such does not expose us to higher risks generally associated with residential mortgage loans such as option ARM, interest-only or subprime mortgage loans. Our portfolio does include mortgage loans on commercial property. Commercial mortgage loan repayments typically do not rely on the sale of the underlying collateral and instead rely on the income producing potential of the collateral as the source of repayment. Ultimately, though, due to the loan amortization period being greater than the contractual loan term, the borrower may be required to refinance the loan, either with us or another lender, or sell the underlying collateral in order to pay off the loan.

        At March 31, 2012, we had $189.9 million of commercial real estate mortgage loans maturing over the next 12 months. In the event we refinance any of these loans because the borrowers are unable to obtain financing elsewhere due to the inability of banks in our market area to make loans, such loans may be considered troubled debt restructurings even though they were performing throughout their terms. Higher levels of troubled debt restructurings may lead to increased classified assets and credit loss provisions.

Regulatory Matters

Capital

        Actual capital amounts and ratios for the Company and the Bank as of March 31, 2012 are presented in the following table. Regulatory capital requirements limit the amount of deferred tax assets that may be included when determining the amount of regulatory capital. Deferred tax asset amounts in excess of the calculated limit are deducted from regulatory capital. At March 31, 2012, such

73

amount was $6.4 million for the Company and $3.1 million for the Bank. No assurance can be given that the regulatory capital deferred tax asset limitation will not increase in the future.

Tangible common equity ratio		N/A			10.35	%		8.86	%

Subordinated Debentures

        The Company issued subordinated debentures to trusts that were established by us or entities we have acquired, which, in turn, issued trust preferred securities, which totaled $105.0 million at March 31, 2012. The Company includes in Tier 1 capital an amount of trust preferred securities equal to no more than 25% of the sum of all core capital elements, which is generally defined as shareholders' equity less goodwill, net of any related deferred income tax liability. At March 31, 2012, the amount of trust preferred securities included in Tier I capital was $105.0 million. While our existing trust preferred securities are grandfathered under the Dodd-Frank Wall Street Reform and Consumer Protection Act that was enacted in July 2010, new issuances will not qualify as Tier 1 capital.

Dividends on Common Stock and Interest on Subordinated Debentures

        Notification to the FRB is required prior to our declaring and paying a dividend to our stockholders during any period in which our quarterly and/or cumulative twelve-month net earnings are insufficient to fund the dividend amount. Interest payments made by the Company on subordinated debentures are considered dividend payments under FRB regulations. This notification requirement is included in regulatory guidance regarding safety and soundness surrounding capital and includes other non-financial measures such as asset quality and credit concentrations. Should the FRB object to our dividend payments, we would be precluded from paying interest on our subordinated debentures. Payments would not commence until approval is received or we no longer need to provide notice under applicable guidance.

Liquidity Management

Liquidity

        The goals of our liquidity management are to ensure the ability of the Company to meet its financial commitments when contractually due and to respond to other demands for funds such as the ability to meet the cash flow requirements of customers who may be either depositors wanting to withdraw funds or borrowers who may need assurance that sufficient funds will be available to meet their credit needs. We have an Executive Asset/Liability Management Committee, or Executive ALM Committee, which is comprised of members of senior management and is responsible for managing balance sheet and off-balance sheet commitments to meet the needs of customers while achieving our financial objectives. Our Executive ALM Committee meets regularly to review funding capacities, current and forecasted loan demand, and investment opportunities.

        The Company manages its liquidity by maintaining pools of liquid assets on-balance sheet, consisting of cash and due from banks, interest-earning deposits in other financial institutions and unpledged investment securities available-for-sale, which we refer to as our primary liquidity. In addition, we also maintain available borrowing capacity under secured borrowing lines with the FHLB and the FRB, which we refer to as our secondary liquidity. In addition to its secured lines of credit, the Company also maintains unsecured lines of credit, subject to availability, of $45.0 million with correspondent banks for purchase of overnight funds.

        The following table provides a summary of the Bank's primary and secondary liquidity levels at the dates indicated:

	March 31, 2012			December 31, 2011

Less secured advances outstanding		(179,500	)		(225,000	)
Net secured borrowing capacity with the FHLB		1,043,304			1,046,925
Secured credit line with the FRB		375,405			347,407
Total secondary liquidity	$	1,418,709		$	1,394,332

        During the three months ended March 31, 2012, the Company's primary liquidity decreased $109.7 million. Liquidity decreased during the period because of the acquisition of PWE Finance in January 2012, which utilized $163.7 million of cash, and because of the $45.5 million reduction in secured FHLB advances. These decreases were partially offset by a $54.5 million increase in investment securities available-for-sale. Our total liquidity and the ratio of primary liquidity to total deposits remain at historically high levels even after the decreases during the current quarter. We expect to continue to maintain higher levels of on-balance sheet liquidity during the remainder of 2012 compared to historical levels until we are able to effectively increase loan portfolio balances. At March 31, 2012, our FHLB advances were secured by all of our loans and leases under a blanket lien. However, $2.6 billion of loans were specifically pledged as collateral for the secured borrowing lines maintained with the FHLB and the FRB.

        In addition to our primary liquidity, we generate liquidity from cash flow from our amortizing loan portfolio and from our large base of core customer deposits, defined as non-interest bearing demand, interest checking, savings and money market accounts. At March 31, 2012, such deposits totaled $3.6 billion and represented 80% of the Company's total deposits. These core deposits are normally less volatile, often with customer relationships tied to other products offered by the Company promoting long lasting relationships and stable funding sources. During the three months ended March 31, 2012, total core deposits increased $26.5 million, mainly in non-interest bearing demand deposits from our small to medium sized business customer base. Some of the growth in our core deposits is attributed to businesses having a tendency to maintain higher cash balances because of current economic conditions and low rate investment alternatives. Deposits from our customers may decline if interest rates increase significantly or if corporate customers move funds from the Company generally. In order to address the Company's liquidity risk as deposit balances may fluctuate, the Company maintains adequate levels of available liquidity.

75

        The following table provides a summary of the Bank's core deposits at the dates indicated:

	March 31, 2012		December 31, 2011
	(In thousands)
Core Deposits:
Non-interest bearing demand	$	1,785,678	$	1,685,799
Interest checking		516,360		500,998
Money market deposits		1,170,960		1,265,282
Savings deposits		163,102		157,480
Total core deposits	$	3,636,100	$	3,609,559

        Our asset/liability policy establishes various liquidity guidelines for the Company. The policy includes guidelines for On-Balance Sheet Liquidity (a measurement of primary liquidity to total deposits), Coverage and Crisis Coverage Ratios (measurements of liquid assets to expected short-term liquidity required for the loan and deposit portfolios under normal and stressed conditions), Loan to Funding Ratio, Wholesale Funding Ratio, and other guidelines developed for measuring and maintaining liquidity. As of March 31, 2012, the Company was in compliance with all liquidity guidelines established in the ALCO policy.

        We may use large denomination brokered time deposits, the availability of which is uncertain and subject to competitive market forces, for liquidity management purposes. At March 31, 2012, the Bank had none of these brokered deposits. In addition, we have $37.4 million of customer deposits that were subsequently participated with other FDIC insured financial institutions through the CDARS program as a means to provide FDIC deposit insurance coverage for the full amount of our participating customers' deposits.

Holding Company Liquidity

        The primary sources of liquidity for the Company, on a stand-alone basis, include dividends from the Bank and our ability to raise capital, issue subordinated debt and secure outside borrowings. The ability of the Company to obtain funds for the payment of dividends to our stockholders and for other cash requirements is largely dependent upon the Bank's earnings. Pacific Western is subject to restrictions under certain federal and state laws and regulations which limit its ability to transfer funds to the Company through intercompany loans, advances or cash dividends.

        Dividends paid by state banks, such as Pacific Western, are regulated by the California Department of Financial Institutions ("DFI") under its general supervisory authority as it relates to a bank's capital requirements. A state bank may declare a dividend without the approval of the DFI as long as the total dividends declared in a calendar year do not exceed either the retained earnings or the total of net profits for three previous fiscal years less any dividends paid during such period. During the three months ended March 31, 2012, PacWest received $8.0 million in dividends from the Bank. For the foreseeable future, any dividends from the Bank to the Company require DFI approval.

        At March 31, 2012, the Company had, on a stand-alone basis, approximately $13.0 million in cash on deposit at the Bank. Management believes that this amount of cash, along with anticipated dividends from the Bank, will be sufficient to fund the Company's 2012 cash flow needs.

Contractual Obligations

        The following table presents the known contractual obligations of the Company as of the date indicated:

	March 31, 2012
	Due Within One Year		Due in One to Three Years		Due in Three to Five Years		Due After Five Years		Total
	(Dollars in thousands)

Total	$	678,114	$	453,912	$	61,439	$	121,378	$	1,314,843

        Time deposits include brokered deposits of $37.4 million of customer deposits that were subsequently participated with other FDIC insured financial institutions through the CDARS program as a means to provide FDIC deposit insurance coverage for the full amount of our customers' deposits.

        Long-term debt obligations include $108.3 million of subordinated debentures. Debt obligations are also discussed in Note 8, Borrowings, Subordinated Debentures and Brokered Deposits, in the Notes to Condensed Consolidated Financial Statements (Unaudited) contained in "Item 1. Condensed Consolidated Financial Statements (Unaudited)." Operating lease obligations are discussed in the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2011. The other contractual obligations relate to our minimum liability associated with our data and item processing contract with a third-party provider and commitments to contribute capital to investments in low income housing project partnerships.

        We believe that we will be able to meet our contractual obligations as they come due through the maintenance of adequate cash levels. We expect to maintain adequate cash levels through profitability, loan and securities repayment and maturity activity, and continued deposit gathering activities. We believe we have in place various borrowing mechanisms for both short-term and long-term liquidity needs.

Off-Balance Sheet Arrangements

        Our obligations also include off-balance sheet arrangements consisting of loan-related commitments, of which only a portion are expected to be funded. At March 31, 2012, our loan-related commitments, including standby letters of credit, totaled $719.4 million. The commitments, which result in funded loans, increase our profitability through net interest income. We manage our overall liquidity taking into consideration funded and unfunded commitments as a percentage of our liquidity sources. Our liquidity sources have been and are expected to be sufficient to meet the cash requirements of our lending activities.

Asset/Liability Management and Interest Rate Sensitivity

Interest Rate Risk

        Our market risk arises primarily from credit risk and interest rate risk inherent in our lending and financing activities. To manage our credit risk, we rely on adherence to our underwriting standards and loan policies, internal loan monitoring and periodic credit review as well as our allowance for credit

77

losses methodology, all of which are administered by the Bank's credit administration department and overseen by the Company's Credit Risk Committee. To manage our exposure to changes in interest rates, we perform asset and liability management activities which are governed by guidelines pre-established by our Executive ALM Committee, and approved by our Asset/Liability Management Committee of the Board of Directors, which we refer to as our Board ALCO. Our Executive ALM Committee monitors our compliance with our asset/liability policies. These policies focus on providing sufficient levels of net interest income while considering capital constraints and acceptable levels of interest rate exposure and liquidity.

        Market risk sensitive instruments are generally defined as derivatives and other financial instruments, which include investment securities, loans, deposits, and borrowings. At March 31, 2012, we had not used any derivatives to alter our interest rate risk profile or for any other reason. However, both the repricing characteristics of our fixed rate loans and floating rate loans and the significant percentage of noninterest-bearing deposits compared to interest-earning assets may influence our interest rate risk profile. Our financial instruments include loans receivable, Federal funds sold, interest-bearing deposits in financial institutions, Federal Home Loan Bank stock, investment securities, deposits, borrowings and subordinated debentures.

        We measure our interest rate risk position on at least a quarterly basis using two methods: (i) net interest income simulation analysis, and (ii) market value of equity modeling. The results of these analyses are reviewed by the Executive ALM Committee and the Board ALCO quarterly. If hypothetical changes to interest rates cause changes to our simulated net present value of equity and/or net interest income outside our pre-established limits, we may adjust our asset and liability mix in an effort to bring our interest rate risk exposure within our established limits.

        We evaluated the results of our net interest income simulation and market value of equity models prepared as of March 31, 2012, the results of which are presented below. Our net interest income simulation indicates that our balance sheet is liability sensitive as rising interest rates would result in a decline in our net interest margin. This profile is primarily a result of (a) the increased origination of fixed rate loans and variable rate loans with initial fixed rate terms over the last several years and (b) declining floating rate construction loans. Our market value of equity model indicates an asset sensitive profile in the up 100 basis points scenario, switching to liability sensitive in the up 200 and up 300 basis point scenarios. An asset sensitive profile would suggest that a sudden sustained increase in rates would result in an increase in our estimated market value of equity, while a liability sensitive profile would suggest that our estimated market value of equity would decrease when rates increase. In general, we view the net interest income model results as more relevant to the Company's current operating profile and manage our balance sheet based on this information. Given the historically low market interest rates as of March 31, 2012, the "down" scenarios at March 31, 2012 are not considered meaningful and are excluded from the following discussion.

Net Interest Income Simulation

        We used a simulation model to measure the estimated changes in net interest income that would result over the next 12 months from immediate and sustained changes in interest rates as of March 31, 2012. This model is an interest rate risk management tool and the results are not necessarily an indication of our future net interest income. This model has inherent limitations and these results are based on a given set of rate changes and assumptions at one point in time. We have assumed no growth in either our interest-sensitive assets or liabilities over the next 12 months; therefore, the results reflect an interest rate shock to a static balance sheet.

        This analysis calculates the difference between net interest income forecasted using both increasing and decreasing interest rate scenarios and net interest income forecasted using a base market interest rate derived from the U.S. Treasury yield curve at March 31, 2012. In order to arrive at the base case,

78

we extend our balance sheet at March 31, 2012 one year and reprice any assets and liabilities that would contractually reprice or mature during that period using the products' pricing as of March 31, 2012. Based on such repricings, we calculate an estimated net interest income and net interest margin.

        The repricing relationship for each of our assets and liabilities includes many assumptions. For example, many of our assets are floating rate loans, which are assumed to reprice to the same extent as the change in market rates according to their contracted index except for floating rate loans tied to our base lending rate which are assumed to reprice upward only after the first 75 basis point increase in market rates. This assumption is due to the fact that we reduced our base lending rate 100 basis points when the Federal Reserve lowered the Federal Funds benchmark rate by 175 basis points in the fourth quarter of 2008. Some loans and investment vehicles include the opportunity of prepayment (imbedded options) and the simulation model uses a prepayment model to estimate these prepayments and reinvest these proceeds at current simulated yields. Our deposit products reprice at our discretion and are assumed to reprice more slowly in a rising or declining interest rate environment and usually reprice at a rate less than the change in market rates. The effects of certain balance sheet attributes, such as fixed rate loans, floating rate loans that have reached their floors, and the volume of noninterest-bearing deposits as a percentage of earning assets, impact our assumptions and consequently the results of our interest rate risk management model. Changes that could vary significantly from our assumptions include loan and deposit growth or contraction, changes in the mix of our earning assets or funding sources, and future asset/liability management decisions, all of which may have significant effects on our net interest income.

        The simulation analysis does not account for all factors that impact this analysis, including changes by management to mitigate the impact of interest rate changes or the impact a change in interest rates may have on our credit risk profile, loan prepayment estimates and spread relationships which can change regularly. In addition, the simulation analysis does not make any assumptions regarding loan fee income, which is a component of our net interest income and tends to increase our net interest margin. Management reviews the model assumptions for reasonableness on a quarterly basis.

        The following table presents as of March 31, 2012, forecasted net interest income and net interest margin for the next 12 months using a base market interest rate and the estimated change to the base scenario given immediate and sustained upward and downward movements in interest rates of 100, 200 and 300 basis points.

Interest Rate Scenario	Estimated Net Interest Income		Percentage Change From Base			Estimated Net Interest Margin			Estimated Net Interest Margin Change From Base
	(Dollars in thousands)
Up 300 basis points	$	255,782		(5.6	)%		5.07	%		(0.29	)%
Up 200 basis points	$	257,793		(4.8	)%		5.11	%		(0.25	)%
Up 100 basis points	$	261,373		(3.5	)%		5.18	%		(0.18	)%
BASE CASE	$	270,914		—			5.36	%		—
Down 100 basis points	$	263,403		(2.8	)%		5.22	%		(0.14	)%
Down 200 basis points	$	259,960		(4.0	)%		5.15	%		(0.21	)%
Down 300 basis points	$	257,743		(4.9	)%		5.11	%		(0.25	)%

        The net interest income simulation model prepared as of March 31, 2012 suggests our balance sheet is liability sensitive. Liability sensitivity indicates that in a rising interest rate environment, our net interest margin would decrease. Due to the historically low market interest rates as of March 31, 2012 the "down" scenarios are not considered meaningful and are excluded from the following discussion. The liability sensitive profile is due mostly to the mix of fixed rate loans to total loans in the loan portfolio relative to our amount of interest-bearing deposits that would reprice as interest rates change. Although $1.7 billion of the $3.5 billion of total loans in the portfolio have variable interest rate terms,

79

only $567.3 million of those variable rate loans will reprice within 12 months. The remaining variable rate loans will behave as if they have fixed rates in the short run because of the effect of interest rate floors and hybrid ARM loan pricing structures of mini-perm commercial real estate loans, which generally contain initial fixed rate terms ranging from three to five years before becoming variable rate.

        In comparing the March 31, 2012 simulation results to December 31, 2011, our profile has remained relatively unchanged while our overall estimated net interest income has increased for all scenarios. The increase in the simulated net interest income is a result of higher earning assets due to the PWE Finance acquisition.

Market Value of Equity

        We measure the impact of market interest rate changes on the net present value of estimated cash flows from our assets, liabilities and off-balance sheet items, defined as the market value of equity, using a simulation model. This simulation model assesses the changes in the market value of our interest sensitive financial instruments that would occur in response to an instantaneous and sustained increase or decrease in market interest rates of 100, 200 and 300 basis points. This analysis assigns significant value to our noninterest-bearing deposit balances. The projections are by their nature forward looking and therefore inherently uncertain, and include various assumptions regarding cash flows and interest rates. This model is an interest rate risk management tool and the results are not necessarily an indication of our actual future results. Actual results may vary significantly from the results suggested by the market value of equity table. Loan prepayments and deposit attrition, changes in the mix of our earning assets or funding sources, and future asset/liability management decisions, among others, may vary significantly from our assumptions. The base case is determined by applying various current market discount rates to the estimated cash flows from the different types of assets, liabilities and off-balance sheet items existing at March 31, 2012.

        The following table shows the projected change in the market value of equity for the set of rate shocks presented as of March 31, 2012:

Interest Rate Scenario	Estimated Market Value		Dollar Change From Base			Percentage Change From Base			Percentage of Total Assets			Ratio of Estimated Market Value to Book Value
	(Dollars in thousands)
Up 300 basis points	$	677,996	$	(62,534	)		(8.4	)%		12.4	%		123.4	%
Up 200 basis points	$	729,803	$	(10,727	)		(1.4	)%		13.4	%		132.8	%
Up 100 basis points	$	750,939	$	10,409			1.4	%		13.8	%		136.6	%
BASE CASE	$	740,530		—			—			13.6	%		134.7	%
Down 100 basis points	$	681,024	$	(59,506	)		(8.0	)%		12.5	%		123.9	%
Down 200 basis points	$	681,465	$	(59,065	)		(8.0	)%		12.5	%		124.0	%
Down 300 basis points	$	681,849	$	(58,681	)		(7.9	)%		12.5	%		124.1	%

        Base case market value of equity increased $33.3 million compared to December 31, 2011. The increase was due to a $30.2 million change in the fair value of borrowings (due to the repayment of the fixed-rate term FHLB advances and subordinated debentures) and a $3.4 million increase in shareholders' equity due to $5.3 million of net earnings for the quarter and a $4.3 million increase in the net unrealized gain on investments, partially offset by $6.5 million of dividends paid during the quarter.

        In comparing the March 31, 2012 simulation results to December 31, 2011, our base case estimated market value of equity has increased while our overall profile has changed from previously being asset sensitive in all scenarios to being asset sensitive in the up 100 basis point scenario and being liability sensitive in the up 200 and up 300 basis point scenarios. The change in the results in the current period resulted from the repayment of $225 million of fixed-rate term FHLB advances and the $18.6 million

80

of fixed-rate subordinated debentures. By removing fixed-rate funding in the current period, market value of equity no longer benefits from the appreciation of these long-term fixed-rate liabilities in rising rate scenarios. The impact of the repayment of the fixed-rate term FHLB advances and subordinated debentures is offset by the impact of the assumed floors in the Company's base lending rate and the significant value placed on the Company's noninterest-bearing deposits for purposes of this analysis. Static balances of noninterest-bearing deposits do not impact the net interest income simulation, while at the same time the value of these deposits increases substantially in the market value of equity model when market rates are assumed to rise.

Gap Analysis

        As part of the interest rate management process, we use a gap analysis. A gap analysis provides information about the volume and repricing characteristics and relationship between the amounts of interest-sensitive assets and interest-bearing liabilities at a particular point in time. An effective interest rate strategy attempts to match the volume of interest sensitive assets and interest-bearing liabilities repricing over different time intervals.

        The following table illustrates the volume and repricing characteristics of our balance sheet at March 31, 2012 over the indicated time intervals:

	Amounts Maturing or Repricing In

        All amounts are reported at their contractual maturity or repricing periods, except for $43.9 million in FHLB stock which is shown as a longer-term repricing investment because of the FHLB's suspended/reduced stock redemptions and dividend payments. This analysis makes certain assumptions as to interest rate sensitivity of savings and NOW accounts which have no stated maturity and have had minimal rate fluctuation in the past three years. Money market accounts are repriced at management's discretion and are generally more rate sensitive.

        The preceding table indicates that we had a negative one-year cumulative gap of $1.1 billion at March 31, 2012, an increase of $341.0 million from the $738.4 million negative one-year gap position at December 31, 2011. The growth in the negative gap was attributable to a reduction in one-year assets of $181.3 million and an increase in one-year liabilities of $159.7 million. The reduction in one-year assets was due mostly to the $169.0 million decline in interest-earning deposits in financial institutions, attributable to the purchase of PWE Finance for $35.0 million and the repayment of $128.7 million of its debt. The growth in one-year liabilities was due mostly to the $179.5 million in overnight FHLB advances which partially replaced the $225.0 million long-term FHLB advances that were prepaid in March 2012. Additionally, one-year time deposits increased by $53.3 million, offset by a decrease of $73.3 million in interest-bearing checking, money market and savings deposits.

        This negative one-year cumulative gap of $1.1 billion suggests that we are liability sensitive and if rates were to increase, our net interest margin would most likely decrease. Conversely, if rates were to decrease, our net interest margin would most likely increase. The ratio of interest-earning assets to interest-bearing liabilities maturing or repricing within one year at March 31, 2012, is 58.7%. This one year gap position indicates that interest expense is likely to be affected to a greater extent than interest income for any changes in interest rates within one year from March 31, 2012.

        The gap table has inherent limitations and actual results may vary significantly from the results suggested by the gap table. The gap table is unable to incorporate certain balance sheet characteristics or factors. The gap table assumes a static balance sheet, and accordingly, looks at the repricing of existing assets and liabilities without consideration of new loans and deposits that reflect a more current interest rate environment. Unlike the net interest income simulation, however, the interest rate risk profile of certain deposit products and floating rate loans that have reached their floors cannot be captured effectively in a gap table. Although the table shows the amount of certain assets and liabilities scheduled to reprice in a given time frame, it does not reflect when or to what extent such repricings may actually occur. For example, interest-bearing demand, money market and savings deposits are shown to reprice in the first three months, but we may choose to reprice these deposits more slowly and incorporate only a portion of the movement in market rates based on market conditions at that time. Alternatively, a loan which has reached its floor may not reprice even though market interest rates change causing such loan to act like a fixed rate loan regardless of its scheduled repricing date. The gap table as presented cannot factor in the flexibility we believe we have in repricing either deposits or the floors on our loans.

        We believe the estimated effect of a change in interest rates is better reflected in our net interest income and market value of equity simulations which incorporate many of the factors mentioned.
