	Note 1.  Organization
	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 the holding company for our Los Angeles‑based wholly‑owned 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. As of June 30, 2014, we had total assets of $15.7 billion, total loans and leases of $11.1 billion, total deposits of $11.7 billion and total stockholders' equity of $3.4 billion.
	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 and leases, including an array of commercial real estate loans and commercial lending products. The Bank has a foundation of locally generated and relationship-based deposits, with 81 full-service branches located throughout the state of California. Our branch operations are located primarily in Southern California extending from San Diego County to California’s Central Coast, and we operate three banking offices in the San Francisco Bay area and two offices in the Central Valley. Our targeted collateral for our real estate loan offerings includes healthcare properties, office properties, industrial properties, multifamily properties, hospitality properties, and retail properties. Our commercial loan products include equipment loans and leases, asset-based loans, lender finance loans and loans secured by borrower future cash flows.
	As a result of the CapitalSource Inc. merger, Pacific Western Bank established the CapitalSource Division, which we also refer to as the National Lending segment. The CapitalSource Division provides on a nationwide basis a full spectrum of financing solutions across numerous industries and property types to small to middle market businesses. Pacific Western’s leasing operation, Pacific Western Equipment Finance, and its group specializing in asset-based lending, CapitalSource Business Finance Group (formerly BFI Business Finance and First Community Financial), also became part of the CapitalSource Division. The CapitalSource Division’s loan and lease origination efforts are conducted through offices located in Chevy Chase, Maryland; Los Angeles and San Jose, California; Denver, Colorado; Chicago, Illinois; New York, New York; and Midvale, Utah. When we refer to "CapitalSource Inc." we are referring to the company acquired on April 7, 2014 and when we refer to the "CapitalSource Division" we are referring to a division of Pacific Western Bank that specializes in middle-market lending on a nationwide basis.
	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.
	We have completed 27 acquisitions from May 2000 through June 30, 2014, including the acquisition of CapitalSource Inc. on April 7, 2014. Since 2000, our acquisitions have been accounted for using the acquisition method of accounting and, accordingly, the operating results of the acquired entities have been included in the condensed consolidated financial statements from their respective acquisition dates. See Note 3, Acquisitions, for more information about the CapitalSource Inc. merger and the acquisition of First California Financial Group, Inc. ("FCAL") on May 31, 2013.
	Significant Accounting Policies
	Except as discussed below, our accounting policies are described in Note 1, Nature of Operations and Summary of Significant Accounting Policies, of our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2013 as filed with the Securities and Exchange Commission ("Form 10-K").
	Basis of Presentation
	Our interim consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, certain disclosures accompanying annual consolidated financial statements are omitted. In the opinion of management, all adjustments and eliminations, consisting solely of normal recurring accruals, considered necessary for the fair presentation of financial statements for the interim periods, have been included. The current period's results of operations are not necessarily indicative of the results that ultimately may be achieved for the year. The interim consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Form 10-K.
	The accompanying financial statements reflect our consolidated accounts. All significant intercompany accounts and transactions have been eliminated.
	Use of Estimates
	We have 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 condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period to prepare these condensed 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 allowance for credit losses, the carrying value of intangible assets, the carrying value of the FDIC loss sharing asset, the realization of deferred tax assets, and the fair value estimates of assets acquired and liabilities assumed in acquisitions.
	As described in Note 3, Acquisitions, the acquired assets and liabilities of CapitalSource Inc. and FCAL were measured at their estimated fair values. We made significant estimates and exercised significant judgment in estimating fair values and accounting for such acquired assets and assumed liabilities.

	CapitalSource Inc. Merger
	We acquired CapitalSource Inc. on April 7, 2014. As part of the merger, CapitalSource Bank (“CSB”), a wholly‑owned subsidiary of CapitalSource Inc., merged with and into Pacific Western Bank. We completed the merger in order to augment our loan and lease generation capabilities and to diversify our loan portfolio.
	Upon closing, we created the CapitalSource Division of the Bank. The CapitalSource Division provides on a nationwide basis a full spectrum of financing solutions across numerous industries and property types to middle market businesses. When we refer to "CapitalSource Inc." we are referring to the company acquired on April 7, 2014 and when we refer to the "CapitalSource Division" we are referring to a division of the Bank that provides on a nationwide basis senior secured real estate loans, equipment loans and leases, asset-based loans, lender finance loans and cash flow loans secured by the enterprise value of the borrowing entity.
	In the merger with CapitalSource Inc., each share of CapitalSource Inc. common stock was converted into the right to receive $2.47 in cash and 0.2837 of a share of PacWest common stock. PacWest issued an aggregate of approximately 56.7 million  shares of PacWest common stock to CapitalSource Inc. stockholders. Based on the closing price of PacWest’s common stock on April 7, 2014 of $45.83 per share, the aggregate consideration paid to CapitalSource Inc. common stockholders and holders of equity awards to acquire CapitalSource Inc. common stock was approximately $3.1 billion.
	CSB was a commercial lender which operated under a California Industrial Loan Bank charter headquartered in Los Angeles, California. CSB provided financial products to small to middle market businesses nationwide and also provided depository products and services to consumers in Southern and Central California. CSB’s loan origination efforts were conducted nationwide, and continue as the CapitalSource Division, with offices located in Chevy Chase, Maryland; Los Angeles, California; Denver, Colorado; Chicago, Illinois; and New York, New York.
	The integration of CSB’s deposit system and the conversion of CSB’s branches to Pacific Western Bank’s operating platform were completed over the weekend of April 12, 2014. CSB had 21 branches, 12 of which were closed in the consolidation with Pacific Western at the close of business on April 11, 2014 and one overlapping Pacific Western branch was closed as well. All remaining branches opened on Monday, April 14, 2014 as Pacific Western branches.
	The CapitalSource Inc. merger has been accounted for under the acquisition method of accounting. The assets and liabilities, both tangible and intangible, were recorded at their estimated fair values as of the merger date. We made significant estimates and exercised significant judgment in estimating fair values and accounting for such acquired assets and liabilities. Such fair values are preliminary estimates and are subject to adjustment for up to one year after the merger date or when additional information relative to the closing date fair values becomes available and such information is considered final, whichever is earlier. The application of the acquisition method of accounting resulted in goodwill of $1.5 billion. All of the recognized goodwill is expected to be non‑deductible for tax purposes. The assignment of goodwill to reporting segments and the fair value of the acquired tax assets, once the final tax returns have been filed, are expected to change.
	As required by the merger agreement and as described in the joint proxy statement/prospectus relating to the merger, the Board of Directors of PacWest adopted a Tax Asset Protection Plan (the “Plan”). This Plan is similar to the Tax Benefit Preservation Plan that CapitalSource Inc. had in place prior to the merger. The purpose of the Plan is to seek to preserve PacWest’s ability to utilize net operating loss carryforwards and certain other tax assets (collectively, the “NOLs”) for U.S. federal income tax purposes that PacWest and certain of its subsidiaries have. The Plan seeks to protect the ability to utilize the NOLs by mitigating the potential for an “ownership change” within the meaning of Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”).
	In general, an “ownership change” would occur if PacWest’s “5‑percent shareholders,” as defined under Section 382 of the Code, collectively increase their ownership in PacWest, in relation to their respective historical low points, by more than 50 percentage points over a rolling three‑year period. In general, institutional holders that file as “investment advisers” for SEC purposes, such as mutual fund companies that hold PacWest common stock on behalf of several individual mutual funds where no single fund owns five percent or more of PacWest’s common stock, are typically not treated as “5‑ percent shareholders” for purposes of Section 382 of the Code.
	First California Financial Group Acquisition
	On May 31, 2013, we acquired First California Financial Group, Inc. As part of this acquisition, First California Bank ("FCB"), a wholly‑owned subsidiary of FCAL, merged with and into Pacific Western.
	In connection with the FCAL acquisition, each share of FCAL common stock was converted into the right to receive 0.2966 of a share of PacWest common stock. The exchange ratio was calculated based on the volume‑weighted average share price of PacWest common stock for the 20 consecutive trading days ending on the second full trading day prior to the receipt of the last of the regulatory approvals required under the merger agreement. PacWest issued an aggregate of approximately 8.4 million shares of PacWest common stock to FCAL stockholders. In addition, 1,094,000 shares of FCAL common stock previously owned by PacWest at a cost of $4.1 million were cancelled in the transaction. These shares were carried in our securities available‑for‑sale portfolio at their estimated market value with their unrealized gain of $5.2 million included in stockholders’ equity at May 31, 2013. Under acquisition accounting, this unrealized gain was recognized in earnings. Based on the closing price of PacWest's common stock on May 31, 2013 of $28.83 per share, the aggregate consideration paid to FCAL common stockholders, including the 1,094,000 shares of FCAL common stock owned by us and cancelled in the merger, was $251.6 million.
	The FCAL acquisition has been accounted for under the acquisition method of accounting. The assets and liabilities, both tangible and intangible, were recorded at their estimated fair values as of the May 31, 2013 acquisition date. The application of the acquisition method of accounting resulted in goodwill of $129.1 million. All of the recognized goodwill is expected to be non‑deductible for tax purposes.
	FCB was a full‑service commercial bank headquartered in Westlake Village, California. FCB provided a full range of banking services, including revolving lines of credit, term loans, commercial real estate loans, construction loans, consumer loans and home equity loans to individuals, professionals, and small to mid‑sized businesses. FCB operated 15 branches throughout Southern California in the Los Angeles, Orange, Riverside, San Bernardino, San Diego, Ventura, and San Luis Obispo Counties. We completed the conversion and integration of the FCB branches to Pacific Western’s operating platform in June 2013 and as a result, we added seven locations to our branch network.
	Unaudited Pro Forma Results of Operations
	The following table presents our unaudited pro forma results of operations for the periods presented as if the CapitalSource Inc. and FCAL acquisitions had been completed on January 1, 2013. The unaudited pro forma results of operations include the historical accounts of the Company, CapitalSource Inc. and FCAL and pro forma adjustments, including the amortization of intangibles with definite lives and the amortization or accretion of any premiums or discounts arising from fair value adjustments for assets acquired and liabilities assumed. The unaudited pro forma information is intended for informational purposes only and is not necessarily indicative of our future operating results or operating results that would have occurred had the CapitalSource Inc. and FCAL acquisitions been completed at the beginning of 2013.

	Note 4.  Goodwill and Other Intangible Assets
	Goodwill arises from the acquisition method of accounting for business combinations and represents the excess of the purchase price over the fair value of the net assets and other identifiable intangible assets acquired. Our intangible assets with definite lives are core deposit intangibles ("CDI") and customer relationship intangibles ("CRI"). In the second quarter of 2014, we wrote-off $6.6 million of goodwill and $0.5 million of CRI related to the reorganization of the legacy PacWest asset financing segment.
	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 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 condensed consolidated statement of earnings.
	CDI and CRI are amortized over their respective estimated 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 weighted average amortization period remaining for all of our CDI and CRI is 5.3 years. The aggregate CDI and CRI amortization expense is expected to be $6.7 million for 2014. The estimated aggregate amortization expense related to these intangible assets for each of the next five years is $5.9 million for 2015, $3.9 million for 2016, $2.5 million for 2017, $2.1 million for 2018 and $1.7 million for 2019.

	The covered private label collateralized mortgage obligations (“CMO’s”) acquired in the FDIC‑assisted acquisition of Affinity Bank in August 2009 are covered by an FDIC loss sharing agreement. The loss sharing provisions for these private label CMO's expire in the third quarter of 2014. Other securities consist primarily of asset‑backed securities. See Note 11, Fair Value Measurements, for information on fair value measurements and methodology.
	As of June 30, 2014, securities available‑for‑sale with a carrying value of $327.4 million were pledged as collateral for borrowings, public deposits and other purposes as required by various statutes and agreements.
	During the three months ended June 30, 2014, we sold $797,000 in other securities for which we realized a gross gain of $89,000. In addition, we sold $323.6 million of the $383.7 million of securities obtained in the CapitalSource Inc. merger for no gain or loss and the proceeds were used to repay borrowings. During the three months ended March 31, 2014, we sold $137.3 million in GSE pass through securities for which we realized a gross gain $4.8 million. These securities were sold as part of our investment portfolio risk management activities. There were no securities sold during the three months ended June 30, 2013. During the six months ended June 30, 2013, we sold $12.4 million in corporate debt securities for which we realized a gross gain of $409,000.
	Realized gains or losses resulting from the sale of securities are calculated using the specific identification method and included in gain on securities.

We reviewed the securities that were in a continuous loss position less than 12 months and longer than 12 months at June 30, 2014, and concluded their losses were a result of the level of market interest rates relative to the types of securities and pricing changes caused by shifting supply and demand dynamics and not a result of downgraded credit ratings or other indicators of deterioration of the underlying issuers' ability to repay. Accordingly, we determined the securities were temporarily impaired and we did not recognize such impairment in the condensed consolidated statements of earnings. 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.
Contractual Maturities
The following table presents the contractual maturities of our available-for-sale securities portfolio based on amortized cost and carrying value as of the date indicated.

Total securities available-for-sale	$	1,517,425	$	1,552,115
Mortgage-backed securities have contractual terms to maturity, but 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.
FHLB Stock
At June 30, 2014, we had a $50.0 million investment in Federal Home Loan Bank of San Francisco ("FHLB SF") stock carried at cost. During the six months ended June 30, 2014, FHLB SF stock increased $22.0 million due primarily to the addition of FHLB SF stock from the CapitalSource Inc. merger. We evaluated the carrying value of our FHLB SF stock investment at June 30, 2014, 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 SF, repurchase activity of excess stock by the FHLB SF at its carrying value, the return on the investment, and our intent and ability to hold this investment for a period of time sufficient to recover our recorded investment.

Originated loans and leases and purchased loans and leases, in each case, for which there was no evidence of credit deterioration at their acquisition date and it was probable that we would be able to collect all contractually required payments, are referred to collectively as non-purchased credit impaired loans, or "Non-PCI loans." Purchased loans for which there was, at the acquisition date, evidence of credit deterioration since their origination and it was probable that we would be unable to collect all contractually required payments are referred to as purchased credit impaired loans, or "PCI loans".
	Non-PCI loans are carried at the principal amount outstanding, net of deferred fees and costs, and in the case of acquired loans, net of purchase discounts and premiums. Deferred fees and costs and purchase discounts and premiums on acquired non-impaired loans are recognized as an adjustment to interest income over the contractual life of the loans using the effective interest method or taken into income when the related loans are paid off or sold.
	PCI loans are accounted for in accordance with ASC Subtopic 310‑30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality.” For PCI loans, at the time of acquisition we (i) calculate the contractual amount and timing of undiscounted principal and interest payments (the "undiscounted contractual cash flows") and (ii) estimate the amount and timing of undiscounted expected principal and interest payments (the "undiscounted expected cash flows"). The difference between the undiscounted contractual cash flows and the undiscounted expected cash flows is the nonaccretable difference. The difference between the undiscounted cash flows expected to be collected and the estimated fair value of the acquired loans is the accretable yield. The nonaccretable difference represents an estimate of the loss exposure of principal and interest related to the PCI loan portfolios; such amount is subject to change over time based on the performance of such loans. The carrying value of PCI loans is reduced by payments received, both principal and interest, and increased by the portion of the accretable yield recognized as interest income.
	In the CapitalSource Inc. merger, the estimated fair value of the loans and leases acquired, excluding PCI loans, was $6.8 billion, the related gross contractual amount was $9.4 billion, and the estimated contractual cash flows not expected to be collected were $839.8 million. The estimated fair value of loans acquired that were identified as PCI loans was $87.8 million.

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 allowances for credit losses.

Those instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the condensed 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.
	The following table presents a summary of the financial instruments described above as of the dates indicated:
		30-Jun-14		31-Dec-13
		(In thousands)
	Loan commitments to extend credit	$	1,813,963	$	1,001,740
	Standby letters of credit	86,055		39,200
	Commitments to purchase equipment being acquired for lease to others	5,679		8,475
		$	1,905,697	$	1,049,415
	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.
	Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. We provide standby letters of credit in conjunction with several of our lending arrangements and property lease obligations. Most guarantees expire within one year from the date of issuance, however, some expire at various dates over the next six years. If a borrower defaults on its commitments subject to any letter of credit issued under these arrangements, we would be required to meet the borrower's financial obligation but would seek repayment of that financial obligation from the borrower. In some cases, borrowers have pledged cash and investment securities as collateral with us under these arrangements.
	In addition, 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. The investments call for capital contributions up to an amount specified in the partnership agreements. As of June 30, 2014 and December 31, 2013, the Company had commitments to contribute capital to these entities totaling $15.0 million and $11.0 million, respectively. In connection with equity investments added from the CapitalSource Inc. merger, we have committed to contribute up to an additional $2.8 million to 13 private equity funds.
	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 or operations.
	FCAL-Related Litigation
	The fourteen lawsuits filed in the Superior Court of the State of California, County of Los Angeles against FCB, among others, by various former clients of political campaign and non-profit organization treasurer Kinde Durkee were settled in court, on July 15, 2014, prior to the hearing on the Bank's motion for summary judgment. The parties informed the court that they had agreed to terms of settlement with respect to all claims, with the exception of the remaining claims in the Bank's interpleader which will direct payment of the funds which remained on deposit on the day that Durkee was arrested. The settlement in the case in chief will be memorialized in writing. The terms of settlement, once performed, will result in a complete settlement and release of all claims which potentially exposed the Bank to liability. The settlement has no material effect on results of operations or liquidity.

Fair Value Measurements	'
	Note 11. Fair Value Measurements
	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.
	The following table presents information on the assets measured and recorded at fair value on a recurring basis as of June 30, 2014:

The following is a description of the valuation methodologies used to measure our assets recorded at fair value (under ASC Topic 820, “Fair Value Measurement”) 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” in the condensed consolidated balance sheets. See Note 5, 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 publicly traded 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 covered 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 be a significant unobservable input and have concluded that the covered 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 changes in default expectations, severity loss factors, or discount rates, which occur all together or in isolation, would result in different fair value measurements.
FHLB stock. Investments in FHLB stock are recorded at cost and measured for impairment quarterly. Ownership of FHLB stock is restricted to member banks and the securities do not have a readily determinable market value. Purchases and sales of these securities are at par value with the issuer. The fair value of investments in FHLB stock is equal to the carrying amount.
Non‑PCI 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‑PCI 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‑PCI nonaccrual loans with an unpaid principal balance less than $250,000 are not individually assessed for impairment but are instead reserved for under our general reserve component.
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. The Level 2 measurement is based on appraisals obtained within the last 12 months and for which a charge‑off was recognized or a change in the specific valuation allowance was made during the six months ended June 30, 2014.
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‑PCI impaired loan balances shown above as measured on a non-recurring basis represent those nonaccrual and restructured loans for which impairment was recognized during the six months ended June 30, 2014. The amounts shown as net losses include the impairment recognized during the six months ended June 30, 2014, for the loan balances shown. Of the $96.8 million of Non-PCI nonaccrual loans at June 30, 2014, $1.7 million were written down to their collateral fair values through charge‑offs during the six months ended June 30, 2014.
Other real estate owned ("OREO"). The fair value of foreclosed real estate 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 for OREO is based on appraisals obtained within the last 12 months and for which a write‑down was recognized during the three months ended June 30, 2014.
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.
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 2. 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.
Borrowings. Borrowings include overnight FHLB advances and other fixed‑rate term 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 and are considered Level 2.
Subordinated debentures. Subordinated debentures are carried at amortized cost. The fair value of subordinated debentures with variable rates is determined using a market discount rate on the expected cash flows.
Commitments to extend 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 excluded from the table above because 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 June 30, 2014, the amounts that will actually be realized or paid at settlement or maturity of the instruments could be significantly different.

	Note 13. Stock Based Compensation
	The Company’s 2003 Stock Incentive Plan, or the 2003 Plan, permits stock-based compensation awards to officers, directors, key employees and consultants. As of June 30, 2014, the 2003 Plan authorized grants of stock‑based compensation instruments to purchase or issue up to 19,686,565 shares of Company common stock, subject to adjustments provided by the 2003 Plan. The authorized amount includes 10,686,565 shares that were added to the 2003 Plan as a result of the CapitalSource Inc. merger. Such shares were available for grant under the former CapitalSource Inc. Equity Incentive Plan and remain available for: (a) former employees of CapitalSource Inc. and CapitalSource Bank who remain employed with the Company, and (b) newly hired employees of the Company. As of June 30, 2014, there were 13,518,374 shares available for grant under the 2003 Plan.
	Restricted Stock
	At June 30, 2014, there were 1,121,850 shares of unvested time‑based restricted common stock outstanding. The awarded shares of time‑based restricted common stock vest over a service period of three to four years from the date of the grant. The time-based restricted common stock vests immediately upon a change in control of the Company, as defined in the 2003 Plan, and upon death of the employee. In April 2014, upon closing of the CapitalSource Inc. merger, 1,013,377 awarded shares of restricted common stock vested due to the triggering of the change of control provision contained within the 2003 Plan. We recorded a $26.1 million charge to earnings for the vesting of such shares. Such amount is included in acquisition, integration and reorganization costs on the accompanying condensed consolidated statements of earnings.
	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 $2.4 million, $1.6 million, and $2.0 million for the three months ended June 30, 2014, March 31, 2014, and June 30, 2013, respectively, and $4.0 million and $3.8 million for the six months ended June 30, 2014 and 2013, respectively. Such amounts are included in compensation expense on the accompanying condensed consolidated statements of earnings.
	The amount of unrecognized compensation expense related to all unvested restricted stock as of June 30, 2014 totaled $42.6 million.

	Note 15. Business Segments
	The Company’s reportable segments consist of “PWB Community Banking,” “National Lending,” and “Other.” In prior periods, the segments consisted of “Banking,” “Asset Financing,” and “Other.” The Asset Financing segment in prior periods included the asset-based lending and leasing operations of Pacific Western Equipment Finance, BFI Business Finance, First Community Financial and Celtic Capital Corporation.
	As a result of the CapitalSource Inc. merger, Pacific Western Bank established the CapitalSource Division, which we also refer to as the National Lending segment. The CapitalSource Division, or National Lending segment, includes the lending operations gained through the CapitalSource Inc. merger, Pacific Western Equipment Finance, and the CapitalSource Business Finance Group (formerly BFI Business Finance and First Community Financial). We reorganized our asset-based lending and leasing operations when we established the CapitalSource Division combining BFI Business Finance and First Community Financial into the Capital Source Business Finance Group, selling Celtic Capital Corporation in July 2014, and having Pacific Western Equipment Finance and the Capital Source Business Finance Group become part of the CapitalSource Division. The CapitalSource Division provides on a nationwide basis a full spectrum of financing solutions across numerous industries and property types to middle market businesses, including senior secured real estate loans, equipment loans and leases, asset-based loans, lender finance loans and cash flow loans secured by the enterprise value of the borrowing entity. The CapitalSource Division’s loan and lease origination efforts are conducted through offices located in Chevy Chase, Maryland; Los Angeles and San Jose, California; Denver, Colorado; Chicago, Illinois; New York, New York; and Midvale, Utah.
	The PWB Community Banking and National Lending segments include all of the operations of Pacific Western Bank. The PWB Community Banking segment includes the operations of Pacific Western Bank, excluding the CapitalSource Division, and includes lending and deposit gathering activities conducted primarily through its California-based branch offices and the Bank’s treasury management function. The Other segment consists of holding company operations which result in expenses principally for compensation, facilities, professional services, interest on subordinated debentures, and the non-bank subsidiary operations including interest income from a loan portfolio and related loan servicing expense.
	The accounting policies of the reported segments are the same as those of the Company described in Note 1, “Nature of Operations and Summary of Significant Accounting Policies,” of our Form 10‑K. Transactions between segments consist primarily of borrowed funds and expense allocations for interest, deposit gathering, corporate overhead and credit loss provisions. Intersegment interest expense is allocated from the PWB Community Banking segment to the National Lending segment based upon National Lending’s average interest-earning assets and operating leases, net of a capital allocation, and the Bank’s total cost of deposits. The PWB Community Banking segment further allocates to the National Lending segment noninterest expense for deposit gathering, maintenance costs and the Bank’s corporate overhead. The provision for credit losses is allocated based on actual charge‑offs for the period as well as net portfolio growth and credit quality trends. All costs associated with investing the Bank’s excess liquidity and the PWB Community Bank’s lending and loan servicing activities are housed in the PWB Community Banking segment. Noninterest income and noninterest expense directly attributable to a segment are assigned to it.

Recently Issued Accounting Standards [Abstract]	'
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	'
	Note 17.  Recently Issued Accounting Standards
	In January 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014‑01, “Investments-Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects.” ASU 2014‑01 allows investors in low‑income housing tax credit (“LIHTC”) entities that meet certain conditions to present the net tax benefits (net of the amortization of the cost of the investment) within income tax expense. The cost of the investments that meet the conditions will be amortized in proportion to (and over the same period as) the total expected tax benefits, including tax credits and other tax benefits, as they are realized on the tax return. ASU 2014‑01 is effective for us on January 1, 2015 and is to be applied retrospectively if investors elect the proportional amortization method. However, if investors have LIHTC investments accounted for under the effective yield method at adoption, they may continue to apply that method for those existing investments. Early adoption is permitted. The adoption of this standard permits expenses currently reported in noninterest expense to be reported in income tax expense. The adoption of this standard in January 2015 will not have a material impact on our financial statements, however, total noninterest expense and income tax expense may change.
	In January 2014, the FASB issued ASU 2014‑04, “Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310‑40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans Upon Foreclosure.” ASU 2014‑04 clarifies when a creditor should reclassify mortgage loans collateralized by residential real estate from loans receivable to other real estate owned. ASU 2014‑04 defines when an in‑substance repossession or foreclosure has occurred and when a creditor is considered to have received physical possession of residential real estate collateralizing a mortgage loan. ASU 2014‑04 is effective for us on January 1, 2015 and can be applied either prospectively or using a modified retrospective transition method, and early adoption is permitted. We do not expect the adoption of this standard in January 2015 to have a material impact on our financial statements.
	In April 2014, the FASB issued ASU 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." ASU 2014-08 is an amendment to Subtopic 205-20 that changes the criteria for reporting discontinued operations by raising the threshold for disposals to qualify as discontinued operations. Effectively, this update aims to reduce the unnecessarily frequent reporting of disposals of small groups of assets that are recurring in nature. The revised definition states that a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. ASU 2014-08 is effective for us for all disposals that occur starting January 2015. The adoption of this standard will not have a material impact on our financial statements.
	ASU 2014-09, "Revenue Recognition (Topic 606): Revenue from Contracts with Customers," was issued May 2014 and will be effective for annual and interim periods beginning after December 15, 2016. Early application is not permitted. ASU 2014-09 requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in GAAP when it becomes effective. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.
	ASU 2014-12, "Compensation-Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period," was issued June 2014 and will be effective for annual and interim periods beginning after December 15, 2015. ASU 2014-12 applies to all reporting entities that grant their employees share-based payments in which the terms of the award provide for a performance target that affects vesting could be achieved after the requisite service period. That is the case when an employee is eligible to retire or otherwise terminate employment before the end of the period in which a performance target (for example, an initial public offering or a profitability target) could be achieved and still be eligible to vest in the award if and when the performance target is achieved. We do not currently have outstanding performance-based awards and, as a result, ASU 2014-12 would not impact our financial statements and its related disclosures.

Segment Reporting [Abstract]	'
Segment Reporting Disclosure [Text Block]	'
	Note 15. Business Segments
	The Company’s reportable segments consist of “PWB Community Banking,” “National Lending,” and “Other.” In prior periods, the segments consisted of “Banking,” “Asset Financing,” and “Other.” The Asset Financing segment in prior periods included the asset-based lending and leasing operations of Pacific Western Equipment Finance, BFI Business Finance, First Community Financial and Celtic Capital Corporation.
	As a result of the CapitalSource Inc. merger, Pacific Western Bank established the CapitalSource Division, which we also refer to as the National Lending segment. The CapitalSource Division, or National Lending segment, includes the lending operations gained through the CapitalSource Inc. merger, Pacific Western Equipment Finance, and the CapitalSource Business Finance Group (formerly BFI Business Finance and First Community Financial). We reorganized our asset-based lending and leasing operations when we established the CapitalSource Division combining BFI Business Finance and First Community Financial into the Capital Source Business Finance Group, selling Celtic Capital Corporation in July 2014, and having Pacific Western Equipment Finance and the Capital Source Business Finance Group become part of the CapitalSource Division. The CapitalSource Division provides on a nationwide basis a full spectrum of financing solutions across numerous industries and property types to middle market businesses, including senior secured real estate loans, equipment loans and leases, asset-based loans, lender finance loans and cash flow loans secured by the enterprise value of the borrowing entity. The CapitalSource Division’s loan and lease origination efforts are conducted through offices located in Chevy Chase, Maryland; Los Angeles and San Jose, California; Denver, Colorado; Chicago, Illinois; New York, New York; and Midvale, Utah.
	The PWB Community Banking and National Lending segments include all of the operations of Pacific Western Bank. The PWB Community Banking segment includes the operations of Pacific Western Bank, excluding the CapitalSource Division, and includes lending and deposit gathering activities conducted primarily through its California-based branch offices and the Bank’s treasury management function. The Other segment consists of holding company operations which result in expenses principally for compensation, facilities, professional services, interest on subordinated debentures, and the non-bank subsidiary operations including interest income from a loan portfolio and related loan servicing expense.
	The accounting policies of the reported segments are the same as those of the Company described in Note 1, “Nature of Operations and Summary of Significant Accounting Policies,” of our Form 10‑K. Transactions between segments consist primarily of borrowed funds and expense allocations for interest, deposit gathering, corporate overhead and credit loss provisions. Intersegment interest expense is allocated from the PWB Community Banking segment to the National Lending segment based upon National Lending’s average interest-earning assets and operating leases, net of a capital allocation, and the Bank’s total cost of deposits. The PWB Community Banking segment further allocates to the National Lending segment noninterest expense for deposit gathering, maintenance costs and the Bank’s corporate overhead. The provision for credit losses is allocated based on actual charge‑offs for the period as well as net portfolio growth and credit quality trends. All costs associated with investing the Bank’s excess liquidity and the PWB Community Bank’s lending and loan servicing activities are housed in the PWB Community Banking segment. Noninterest income and noninterest expense directly attributable to a segment are assigned to it.
