BASIS OF PRESENTATION	'
BASIS OF PRESENTATION	'
	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 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.
	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 commercial, real estate construction, equipment finance leases, SBA guaranteed and consumer loans; and providing other business-oriented products. Our operations are primarily located in Southern California extending from San Diego County to California's Central Coast; we also operate three banking offices in the San Francisco Bay area, a leasing operation based in Utah, and asset-based lending operations based in Arizona as well as San Jose and Santa Monica, California. 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, Colorado, Minnesota, and the Pacific Northwest. Our equipment leasing function 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, with 73 branches located across 10 California counties. The Bank has a relatively low cost of funds due to a high percentage of noninterest-bearing and low cost deposits.
	We have completed 26 acquisitions from May 2000 through September 30, 2013, including the acquisition of First California Financial Group, Inc. ("FCAL") on May 31, 2013. 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 FCAL acquisition and the acquisitions that we made in 2012, and Note 18, Subsequent Events, for information regarding the announcement of the CapitalSource, Inc. merger.
	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.
	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 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, and the realization of deferred tax assets.
	As described in Note 3 below, we completed the acquisition of FCAL on May 31, 2013. The acquired assets and liabilities of FCAL were measured at their estimated fair values. Management made significant estimates and exercised significant judgment in estimating fair values and accounting for the acquired assets and assumed liabilities of FCAL.
	Reclassifications
	Certain prior period amounts have been reclassified to conform to the current period's presentation format. Starting with the June 30, 2013 quarter-end, loan tables presented non-purchased credit impaired ("Non-PCI") and purchased credit impaired ("PCI") loan categories in addition to covered and non-covered loan information. Previously the loan tables only presented covered and non-covered loan categories.

DISCONTINUED OPERATIONS	'
	NOTE 2—DISCONTINUED OPERATIONS
	In connection with the acquisition of FCAL, we acquired Electronic Payment Services ("EPS"), a division of the Bank that is being discontinued. Accordingly, all income and expense related to EPS have been removed from continuing operations and are included in the condensed consolidated statements of earnings under the caption "Earnings (loss) from discontinued operations." For the three months ended September 30, 2013, revenues (net interest income plus noninterest income) and pre-tax income for the EPS division were $1.1 million and $39,000, respectively. For the period from acquisition date to September 30, 2013, revenues and pre-tax loss for the EPS division were $1.6 million and $42,000, respectively. Liabilities of the EPS division, which consist primarily of noninterest-bearing deposits, are included in the condensed consolidated balance sheets under the caption "Discontinued operations." Included in the EPS noninterest-bearing deposits are $104.8 million of brokered deposits. For segment reporting purposes, the EPS division is included in our Banking Segment.

	First California Financial Group Acquisition
	On May 31, 2013, PacWest Bancorp ("PacWest") completed the acquisition of First California Financial Group, Inc. ("FCAL"). As part of the acquisition, First California Bank ("FCB"), a wholly-owned subsidiary of FCAL, merged with and into Pacific Western. The acquisition, which was first announced on November 6, 2012, was concluded following receipt of shareholder approval from both institutions and all required regulatory approvals.
	In 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, approximately one million shares of FCAL common stock previously owned by PacWest were cancelled in the transaction. 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, plus the acquisition date fair value of the FCAL shares of common stock cancelled in the merger, was $251.6 million.
	The integration of FCB systems and the conversion of FCB's branches to PWB's operating platform were completed in June 2013. FCB had 15 branches, eight of which overlapped with existing PWB branches. Six of the FCB branches and two PWB branches were closed as part of the integration and consolidation plan. As a result PWB added seven locations to its branch network.
	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 throughout Southern California in the Los Angeles, Orange, Riverside, San Bernardino, San Diego, Ventura, and San Luis Obispo Counties. We made this acquisition to expand our presence in Southern California.
	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. Such fair values are preliminary estimates and are subject to adjustment for up to one year after the acquisition date or when additional information relative to the closing date fair values becomes available and such information is considered final, whichever is earlier. While the fair values are preliminary we believe there will not be material adjustments to the amounts recorded with the exception of the acquired tax assets, which will be finalized once the final tax returns have been filed. The application of the acquisition method of accounting resulted in goodwill of $136.2 million. All of the recognized goodwill is expected to be non-deductible for tax purposes.
	During the third quarter of 2013, we recorded a $5.2 million non-taxable securities gain in earnings related to the FCAL acquisition. Prior to the closing of the FCAL acquisition, we acquired 1,094,000 shares of FCAL common stock at a cost of $4.1 million. 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. Our accounting for the FCAL acquisition included these shares at their historical cost. We should have included these shares at their estimated fair value and recognized an acquisition-related securities gain of $5.2 million at May 31, 2013. We corrected for this in the third quarter of 2013 by recognizing the gain with an offset to goodwill.
	American Perspective Bank Acquisition
	On August 1, 2012, Pacific Western completed the acquisition of American Perspective Bank, or APB, previously headquartered in San Luis Obispo, California. Pacific Western acquired all of the outstanding common stock of APB for $58.1 million in cash and APB was merged with and into Pacific Western; we refer to this transaction as the APB acquisition. APB operated two branches located in San Luis Obispo and Santa Maria, California, and a loan production office located in Paso Robles, California, which has since been converted to a full-service branch. The APB acquisition strengthened our presence in the Central Coast region.
	Celtic Capital Corporation Acquisition
	On April 3, 2012, Pacific Western completed the acquisition of Celtic Capital Corporation, or Celtic, an asset-based lending company based in Santa Monica, California. Pacific Western acquired all of the capital stock of Celtic for $18 million in cash and Celtic became a wholly-owned subsidiary of Pacific Western; we refer to this transaction as the Celtic acquisition. Celtic focuses on providing asset-based loans to borrowers across the United States for amounts generally up to $5 million. The Celtic acquisition diversified our loan portfolio, expanded our product lines, and deployed excess liquidity into higher yielding assets.
	Pacific Western Equipment Finance Acquisition
	On January 3, 2012, Pacific Western completed the acquisition of Pacific Western Equipment Finance (formerly known as Marquette Equipment Finance, and which we refer to as EQF), an equipment leasing company based in Midvale, Utah. Pacific Western acquired all of the capital stock of EQF for $35 million in cash and EQF became a division of Pacific Western; we refer to this transaction as the EQF acquisition. The EQF acquisition diversified our lending portfolio, expanded our product lines, and deployed excess liquidity into higher yielding assets.
	Unaudited Pro Forma Results of Operations
	The following table presents our unaudited pro forma results of operations for the periods presented as if the FCAL acquisition had been completed on January 1, 2012. The unaudited pro forma results of operations include the historical accounts of the Company and FCAL and pro forma adjustments as may be required, 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 FCAL acquisition been completed at the beginning of 2012. No assumptions have been applied to the pro forma results of operations regarding possible revenue enhancements, expense efficiencies or asset dispositions.
	No pro forma results of operations information have been provided for the three months ended September 30, 2013 as FCAL was acquired on May 31, 2013 and the actual results of FCAL and the Company are included together for this three-month period in the condensed consolidated statements of earnings.

GOODWILL AND OTHER INTANGIBLE ASSETS	'
GOODWILL AND OTHER INTANGIBLE ASSETS	'
	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. 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.
	The following table presents the changes in the carrying amount of goodwill for the period indicated:
		Goodwill
		(In thousands)
	Balance, December 31, 2012	$	79,866
	Adjustment to APB goodwill		(193	)
	Non-tax deductible addition from the FCAL acquisition		136,189
	Balance, September 30, 2013	$	215,862
	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 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 for the CDI addition from the FCAL acquisition is 3.1 years. The weighted average amortization period remaining for all of our CDI and CRI is 3.0 years. The aggregate CDI and CRI amortization expense is expected to be $5.4 million for 2013. The estimated aggregate amortization expense related to these intangible assets for each of the next five years is $5.3 million for 2014, $4.8 million for 2015, $3.0 million for 2016, $1.6 million for 2017, and $1.3 million for 2018.

	The covered private label collateralized mortgage obligations ("CMO's") were acquired in the FDIC-assisted acquisition of Affinity Bank in August 2009 and are covered by an FDIC loss sharing agreement. The loss sharing provisions of this agreement expire in the third quarter of 2014 for non-single family covered assets such as these private label CMO's. Other securities consist primarily of asset backed securities and collateralized loan obligations. See Note 11, Fair Value Measurements, for information on fair value measurements and methodology.

	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.
	At September 30, 2013, the estimated fair value of residential mortgage-backed debt securities issued by the Federal National Mortgage Association ("Fannie Mae") and the Federal Home Loan Mortgage Corporation ("Freddie Mac") that were held in our portfolio was approximately $774.8 million. We do not own any equity securities issued by Fannie Mae or Freddie Mac.
	As of September 30, 2013, securities available-for-sale with a carrying value of $201.9 million were pledged as collateral for borrowings, public deposits and other purposes as required by various statutes and agreements.
	There were no securities sold during the three months ended September 30, 2013. However, we recorded a $5.2 million non-taxable gain to recognize our previously-held equity interest in FCAL common stock at its fair value as of the acquisition date rather than at its historical cost. During the three months ended March 31, 2013, we sold $12.4 million in corporate debt securities for which we realized a $409,000 gross gain. These securities were sold as part of our investment portfolio risk management activities to reduce price volatility and duration.

We reviewed the securities that were in a continuous loss position less than 12 months and longer than 12 months at September 30, 2013, 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' ability to repay. Accordingly, we determined that 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.

FHLB Stock
At September 30, 2013, the Company had a $34.1 million investment in Federal Home Loan Bank of San Francisco ("FHLB") stock carried at cost. During the third quarter of 2013, FHLB stock decreased $5.0 million due to redemptions by the FHLB. We evaluated the carrying value of our FHLB stock investment at September 30, 2013, 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, repurchase activity of excess stock by the FHLB 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.

LOANS AND LEASES	'
	NOTE 6—LOANS AND LEASES
	The Company's loan portfolio consists of (1) purchased credit-impaired ("PCI") loans and (2) non-purchased credit-impaired ("Non-PCI") loans. PCI loans represent acquired loans for which there is, at the acquisition date, evidence of credit deterioration since their origination and it is probable that we would be unable to collect all contractually required payments. Such loans are accounted for in accordance with ASC Subtopic 310-30, "Loans and Debt Securities Acquired with Deteriorated Credit Quality." Non-PCI loans are comprised of originated loans and acquired non-impaired loans for which there is no evidence of credit deterioration at their acquisition date and it is probable that we would be able to collect all contractually required payments. Originated loans are carried at the principal amount outstanding, net of unearned income. Unearned income is 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. The purchase discount on acquired non-impaired loans is recognized as an adjustment to interest income over the contractual life of such loans using the effective interest method or taken into income when the related loans are paid off or sold.
	We further present our loans by "covered" and "non-covered" loan categories. Covered loans represent loans covered by loss sharing agreements with the FDIC for which we will be reimbursed for a substantial portion of any future losses under the terms of the agreements. Covered loans also include a portion of the loans acquired in the FCAL acquisition as FCB had acquired two failed banks from the FDIC for which the loss sharing agreements with the FDIC remain in effect. Non-covered loans and leases represent loans and leases not covered by FDIC loss sharing agreements.

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.

FDIC LOSS SHARING ASSET	'
FDIC LOSS SHARING ASSET	'
	NOTE 8—FDIC LOSS SHARING ASSET
	The FDIC loss sharing asset relates to assets covered by the loss sharing agreements between the Bank and the FDIC arising from the acquisitions of Los Padres Bank and Affinity Bank and, through the FCAL acquisition, the assumption of the loss sharing agreements between First California Bank and the FDIC arising from FCB's acquisition of Western Commercial Bank ("Western Commercial") and San Luis Trust Bank ("San Luis"). The FDIC loss sharing asset related to Western Commercial and San Luis was measured at its fair value as of May 31, 2013 in conjunction with the FCAL acquisition. The FDIC loss sharing asset related to Los Padres and Affinity was measured at its estimated fair value at the respective acquisition dates.
	An increase in the expected amount of losses on the covered assets will increase the FDIC loss sharing asset; such increase is recognized through a credit to FDIC loss sharing income. Recoveries on previous losses paid to us by the FDIC reduce the FDIC loss sharing asset by a charge to FDIC loss sharing income. In addition, decreases in the expected amount of losses on covered assets will decrease the amount of funds expected to be collected from the FDIC and will therefore reduce the FDIC loss sharing asset through higher prospective amortization expense. The FDIC loss sharing asset is being amortized to its estimated value over the lesser of the term of the loss sharing agreements or the remaining contractual life of the assets covered by the loss sharing agreements.
	Both the Western Commercial and San Luis loss sharing agreements contain true-up provisions, under which we will owe the FDIC amounts at the end of the loss sharing agreements based on the performance of the covered assets. The true-up liability is included in other liabilities in the accompanying condensed consolidated balance sheets.
	The following table presents the changes in the FDIC loss sharing asset for the period indicated:

The debt is secured by the equipment in the leases and all interest rates are fixed. As of September 30, 2013, the weighted average maturity of the debt was 2.0 years.
	As of September 30, 2013 and December 31, 2012, there were no outstanding FHLB advances. Our aggregate remaining borrowing capacity under the FHLB secured borrowing lines was $1.3 billion at September 30, 2013. As of September 30, 2013, our FHLB advances facility was secured by: (1) a blanket lien on certain qualifying loans in our loan portfolio, which were not pledged to the Federal Reserve Bank of San Francisco ("FRBSF"), and (2) available-for-sale securities with a carrying value of $11.5 million. Additionally, the Bank had secured borrowing capacity from the FRBSF of $467.8 million at September 30, 2013, secured by $589.9 million of certain qualifying loans. As of September 30, 2013, the Bank also had unsecured lines of credit of $80.0 million with correspondent banks for the purchase of overnight funds; these lines are subject to availability of funds.

	Interest payments made by the Company on subordinated debentures are considered dividend payments under the Board of Governors of the Federal Reserve System ("FRB") regulations. Bank holding companies, such as PacWest Bancorp, are required to notify the FRB prior to declaring and paying a dividend to stockholders during any period in which quarterly and/or cumulative twelve-month net earnings are insufficient to fund the dividend amount, among other requirements. We are not required to make such notification to the FRB.
	Debt Termination Expense—FHLB Advances and Subordinated Debentures
	In March 2012, the Company incurred $22.6 million in debt termination expense related to the repayment of $225.0 million in fixed-rate term FHLB advances and the early redemption of $18.6 million in fixed-rate subordinated debentures. The Company used a combination of excess cash and collateralized overnight FHLB advances to repay these debt instruments.
	Brokered Deposits
	Brokered time deposits totaled $51.1 million at September 30, 2013, and $37.7 million at December 31, 2012, all of which were part of the CDARS program. The CDARS program represents deposits that are participated with other FDIC insured financial institutions as a means to provide FDIC deposit insurance coverage for the full amount of our customers' deposits. In addition, liabilities from discontinued operations at September 30, 2013 included $104.8 million of noninterest-bearing brokered deposits.

	NOTE 10—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, standby letters of credit, and commitments to purchase equipment being acquired for lease to others. 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:
		September 30,		December 31,
		2013		2012
		(In thousands)
	Loan commitments to extend credit	$	1,069,451	$	849,607
	Standby letters of credit		39,586		27,534
	Commitments to purchase equipment being acquired for lease to others		2,964		4,399
		$	1,112,001	$	881,540
	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. 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.
	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 September 30, 2013 and December 31, 2012, the Company had commitments to contribute capital to these entities totaling $9.3 million and $10.8 million, respectively.
	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 Merger-Related Litigation
	As set forth below, there are a number of litigation matters pending against FCB. On May 31, 2013, pursuant to the FCAL acquisition, FCAL merged with and into PacWest, and FCB merged with and into Pacific Western. Pursuant to the merger agreement executed between FCAL and PacWest on November 6, 2012, PacWest has assumed the defense of the litigation matters and would assume liability for the results in the event of an adverse result in the cases.
	Eleven lawsuits have been 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. The lawsuits are entitled (i) Wardlaw, et al. v. First California Bank, et al. (Case No. SC 114232), filed September 23, 2011; (ii) Lou Correa for State Senate, et al. v. First California Bank, et al. (Case No. BC 479872), filed February 29, 2012; (iii) Committee to Re-elect Lorreta Sanchez, et al. v. First California Bank, et al. (Case No. BC 479873), filed February 29, 2012, (iv) Holden for Assembly v. First California Bank, et al. (Case No. BC 489604), filed August 3, 2012; (v) Latino Diabetes Ass'n v. First California Bank, et al. (Case No. BC 489605), filed August 3, 2012; (vi) Jose Solorio Assembly Officeholder Committee, et al. v. First California Bank, et al. (Case No. 492855), filed September 27, 2012; (vii) Foster for Treasurer 2014, et al. v. First California Bank, et al. (Case No. BC 492878), filed September 27, 2012; (viii) Los Angeles County Democratic Central Committee, et al. v. First California Bank, et al. (Case No. BC 492854), filed September 27, 2012; (ix) National Popular Vote v. First California Bank, et al. (Case No. BC 501213), filed February 19, 2013; (x) Zine for City Council v. First California Bank, et al. (Case No. BC 504476), filed April 2, 2013; and (xi) Rothman v. First California Bank, et al. (Case No. BC 511180), filed June 5, 2013. Plaintiffs in each of the cases claim, among other things, that FCB aided and abetted a fraud and unlawful conversion by Ms. Durkee and/or her affiliated company of funds held in accounts at FCB. Based largely on the same alleged conduct, plaintiffs also assert claims for an alleged violation of California Business & Professions Code Section 17200 and for declaratory relief. Plaintiffs seek compensatory and punitive damages, as well as various forms of equitable and declaratory relief.
	Each of the cases is pending before the same judge, who is coordinating their progress. FCB has answered each of the complaints, and the parties are engaged in discovery. A trial date has been scheduled for August 13, 2014.
	On September 23, 2011, FCB filed a Complaint-in-Interpleader in the Superior Court of the State of California, County of Los Angeles (Case No. BC 470182), pursuant to which FCB interpleaded the sum of $2,539,049 as the amounts on deposit in accounts at FCB that were controlled by Ms. Durkee on behalf of the several hundred named defendants (the "Interpleader Action"). FCB seeks an order requiring the defendants to interplead and litigate their respective claims, discharging FCB from liability, and restraining proceedings or actions against FCB by the defendants with respect to those amounts. On December 6, 2011, the Interpleader Action was designated as complex and transferred to the Superior Court's complex litigation division. It has been related to the other pending actions that relate to the conduct of Ms. Durkee.
	On June 18, 2012, FCB moved for summary judgment in the Interpleader Action. At hearings held in late 2012 and early 2013, the Superior Court entered summary judgment with respect to a majority of the accounts at issue. Those sums have been paid by the Superior Court to the former accountholders.
	Since September 30, 2013, the 11 lawsuits has grown to 14 lawsuits. The allegations in the three new suits were filed by former clients of Kinde Durkee and each new suit makes claims identical to the original 11 lawsuits. The parties participated in a mediation on October 16, 2013. The mediation was unsuccessful and the plaintiffs made a demand which was not reasonable. At the October 30, 2013 status conference, the judge ordered the parties to meet and confer regarding a framework for trying the cases. The Court set a further status conference for December 19, 2013.
	We continue to believe we have made the appropriate accrual for any liabilities that may arise out of the Kinde Durkee litigation matters, but we are unable to determine with certainty whether there will be any material impact on the Company's financial statements or operations.
	CapitalSource Merger-Related Litigation
	Between July 24, 2013 and September 19, 2013, 11 putative stockholder class action lawsuits (the "Merger Litigations") were filed against PacWest and certain other defendants in connection with PacWest entering into the CapitalSource Merger Agreement in which PacWest agreed to acquire CapitalSource. The CapitalSource Merger Agreement was publicly announced on July 22, 2013. Five of the 11 actions were filed in Superior Court of California, Los Angeles County: (1) Engel v. CapitalSource, Inc. et al., Case No. BC516267, filed on July 24, 2013; (2) Miller v. Fremder et al., Case No. BC516590, filed on July 29, 2013; (3) Basu v. CapitalSource, Inc. et al., Case No. BC516775, filed on July 31, 2013; (4) Holliday v. PacWest Bancorp et al., Case No. BC517209, filed on August 5, 2013 and (5) Iron Workers Mid-South Pension Fund v. CapitalSource Inc. et al., Case No . BC517698, filed on August 8, 2013 (collectively, the "California Actions"). The other six actions were filed in the Court of Chancery of the State of Delaware: (1) Fosket v. Byrnes et al., Case No. 8765, filed on August 1, 2013; (2) Bennett v. CapitalSource, Inc. et al., Case No. 8770, filed on August 2, 2013; (3) Chalfant v. CapitalSource et al., Case No. 8777, filed on August 6, 2013; (4) Oliveira v. CapitalSource, Inc. et al., Case No. 8779, filed on August 7, 2013; (5) Desai v. CapitalSource, Inc. et al., Case No. 8804, filed on August 13, 2013; and (6) Fattore v. CapitalSource, Inc. et al., Case No. 8927, filed on September 19, 2013 (collectively, the "Delaware Actions").
	On August 15, 2013, the Delaware Actions were consolidated into a single action, captioned In re CapitalSource Inc. Stockholder Litigation, Consol. C.A. No. 8765-CS, and assigned to Chancellor Leo E. Strine. On September 25, 2013, plaintiffs in the Delaware Actions filed a Verified Consolidated Amended Class Action Complaint (the "Delaware Consolidated Complaint"). On September 17, 2013, the California Actions were consolidated into a single action, captioned In re CapitalSource Inc. Shareholder Litigation, Lead Case No. BC516267, and assigned to Judge Elihu M. Berle. On October 2, 2013, plaintiffs in the California Actions filed an Amended Consolidated Complaint (the "California Consolidated Complaint").
	The Delaware Consolidated Complaint and the California Consolidated Complaint each allege that the members of the CapitalSource board of directors breached their fiduciary duties to CapitalSource stockholders by approving the proposed merger for inadequate consideration; approving the transaction in order to obtain benefits not equally shared by other CapitalSource stockholders; entering into the merger agreement containing preclusive deal protection devices; and failing to take steps to maximize the value to be paid to the CapitalSource stockholders. The Delaware Consolidated Complaint and the California Consolidated Complaint also each allege claims against CapitalSource and PacWest for aiding and abetting these alleged breaches of fiduciary duties. Plaintiffs in these actions seek, among other things, declaratory and injunctive relief concerning the alleged breaches of fiduciary duties, injunctive relief prohibiting consummation of the merger, rescission, an accounting by defendants, damages and attorneys' fees and costs, and other and further relief. The judge in the Delaware Actions ruled on October 23, 2013, that discovery would proceed in the Delaware Actions and that it would be shared with the plaintiffs in the California Actions and that the California Actions would be stayed while that process takes place. Thereafter, on October 28, 2013, the California Actions' plaintiffs stipulated in the California Actions that they would participate in the discovery process in the Delaware Actions and the administrative stay in the California Actions will remain in place unless and until the Delaware Actions are abandoned. At this stage, it is not possible to predict the outcome of the proceedings or their impact on CapitalSource or PacWest.

FAIR VALUE MEASUREMENTS	'
	NOTE 11—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 government agency and government-sponsored enterprise 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 also includes unobservable inputs from a pricing service not corroborated by observable market data, and includes our covered 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.
	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 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 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 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.
Impaired loans (excluding PCI 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 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. 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 nine months ended September 30, 2013.
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 represent those nonaccrual and restructured loans for which impairment was recognized during the nine months ended September 30, 2013. The amounts shown as net losses include the impairment recognized during the nine months ended September 30, 2013, for the loan balances shown. Of the $50.8 million of nonaccrual loans at September 30, 2013, $1.1 million were written down to their collateral 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 for OREO is based on appraisals obtained within the last 12 months and for which a write-down was recognized during the nine months ended September 30, 2013.
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 U.S. 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 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 are carried at amortized cost. 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 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 September 30, 2013, the amounts that will actually be realized or paid at settlement or maturity of the instruments could be significantly different.

	NOTE 13—STOCK COMPENSATION PLANS
	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 September 30, 2013, the 2003 Plan authorized grants of stock-based compensation instruments to purchase or issue up to 6,500,000 shares of authorized but unissued Company common stock, subject to adjustments provided by the 2003 Plan. As of September 30, 2013, there were 1,431,481 shares available for grant under the 2003 Plan.
	Restricted Stock
	At September 30, 2013, there were outstanding 916,462 shares of unvested time-based restricted common stock and 875,000 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 four 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 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 $2.4 million, $2.0 million, and $1.4 million for the three months ended September 30, 2013, June 30, 2013, and September 30, 2012, respectively, and $6.1 million and $4.3 million for the nine months ended September 30, 2013 and 2012, respectively. Such amounts are included in compensation expense on the accompanying condensed consolidated statements of earnings.
	We are currently not recognizing any compensation expense for 575,000 of the 875,000 shares of performance-based restricted stock as management has concluded that it is improbable that the respective financial targets related to these outstanding 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 performance-based restricted stock for which amortization is not being recognized totaled $19.0 million at September 30, 2013. The amount of unrecognized compensation expense related to all unvested restricted stock as of September 30, 2013 totals $41.7 million.
	As noted above, both time-based and performance-based restricted stock vests upon a change in control of the Company. The CapitalSource, Inc. merger, expected to close in the first quarter of 2014, will trigger restricted stock vesting under the change in control provisions within the 2003 Plan. The remaining unamortized expense for all the performance-based and time-based awards will be recognized at that time. See also Note 18, Subsequent Events.

	NOTE 17—RECENTLY ISSUED ACCOUNTING STANDARDS
	In July 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-11, "Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists." Under ASU 2013-11, an unrecognized tax benefit should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. However, to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position, or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. ASU 2013-11 is effective for us on January 1, 2014 and is to be applied prospectively, although early adoption and retrospective adoption are permitted. The adoption of this standard is not expected to have any material effect on our financial statements.

	PacWest and CapitalSource Merger Announcement
	On July 22, 2013, PacWest announced the signing of a definitive agreement and plan of merger (the "Agreement") whereby PacWest and CapitalSource, Inc. ("CSE") will merge in a transaction valued at approximately $2.4 billion. The combined company will be called PacWest Bancorp and the combined subsidiary bank will be called Pacific Western Bank. The CSE national lending operation will continue to do business under the name CapitalSource as a division of Pacific Western Bank.
	Under the terms of the Agreement, CSE shareholders will receive $2.47 in cash and 0.2837 shares of PacWest common stock for each share of CSE common stock. Based on the closing price of PacWest shares on November 4, 2013 of $38.21, the total value of the CSE per share merger consideration is $13.31.
	As of September 30, 2013, on a pro forma consolidated basis, the combined company would have had approximately $15.4 billion in assets with 95 branches throughout California.

BASIS OF PRESENTATION	'
Basis of Presentation	'
	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.
Use of Estimates	'
	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 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, and the realization of deferred tax assets.
	As described in Note 3 below, we completed the acquisition of FCAL on May 31, 2013. The acquired assets and liabilities of FCAL were measured at their estimated fair values. Management made significant estimates and exercised significant judgment in estimating fair values and accounting for the acquired assets and assumed liabilities of FCAL.
Reclassifications	'
	Reclassifications
	Certain prior period amounts have been reclassified to conform to the current period's presentation format. Starting with the June 30, 2013 quarter-end, loan tables presented non-purchased credit impaired ("Non-PCI") and purchased credit impaired ("PCI") loan categories in addition to covered and non-covered loan information. Previously the loan tables only presented covered and non-covered loan categories.
