Notes to Condensed Consolidated Financial Statements (Unaudited)

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 PacWest Bancorp together with its subsidiaries on a consolidated basis. When we refer to “PacWest” or to the holding company, we are referring to PacWest Bancorp, the parent company, on a stand‑alone basis. As of June 30, 2015, the Company had total assets of $16.7 billion, gross loans and leases of $12.1 billion, total deposits of $12.6 billion and total stockholders' equity of $3.6 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 and originating loans and leases, including an array of commercial real estate loans and commercial lending products. The Bank strives to attract locally generated and relationship-based deposits, with 80 full-service branches located primarily in Southern California, extending from San Diego County to California’s Central Coast. The Bank also operates three banking offices in the San Francisco Bay area and four banking offices in the Central Valley. The collateral for 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, loans to finance companies, 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 lends throughout the United States, providing middle-market businesses asset-secured loans, equipment-secured loans and leases, cash flow loans, and real estate loans secured by various property types. The Bank's leasing operation, Pacific Western Equipment Finance, and its group specializing in asset-based lending, CapitalSource Business Finance Group, are 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; St. Louis, Missouri; 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 the 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 include 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, 2015, including the acquisition of CapitalSource Inc. 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 consolidated financial statements from their respective acquisition dates. See Note 3, Acquisitions, for more information about the CapitalSource Inc. merger.

Square 1 Financial, Inc. Merger Announcement

On March 2, 2015, PacWest announced the signing of an agreement and plan of merger (the “Agreement”) whereby PacWest and Square 1 Financial, Inc. (“Square 1”) will merge in a transaction currently valued at approximately $867 million. The surviving company will be PacWest Bancorp and the surviving subsidiary bank will be Pacific Western Bank, with the banking operations of Square 1 conducted under the trade name of Square 1 Bank, a division of Pacific Western Bank.

Under the terms of the Agreement, Square 1 stockholders will receive 0.5997 shares of PacWest common stock for each share of Square 1 common stock. The total value of the per share merger consideration is $27.49, based on the $45.84 closing price of PacWest common stock on February 27, 2015, the last trading day before the transaction was announced.

As of June 30, 2015, on a pro forma consolidated basis, after giving effect to the Square 1 merger, the Company would have had approximately $21.1 billion in assets with 80 branches throughout California and one branch in North Carolina.

The transaction, currently expected to close in the fourth quarter of 2015, is subject to customary conditions, including the approval of bank regulatory authorities. The transaction was approved by the Square 1 stockholders on July 29, 2015.

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, 2014 as filed with the Securities and Exchange Commission ("Form 10-K").

Accounting Standard Adopted in 2015

Effective January 1, 2015, the Company adopted new accounting guidance for investments in affordable housing projects that qualify for the low-income housing tax credit. As a result of the adoption of this new guidance, the Company made an accounting policy election to amortize the initial cost of its qualifying investments in proportion to the tax credits and other benefits received and to present the amortization as a component of income tax expense, referred to as the proportional amortization method. Previously, investments in low-income housing tax credits were accounted for under the equity method and such amortization was presented in other expense. The guidance was required to be applied retrospectively and accordingly, prior period amounts for other expense and tax expense have been revised to conform to the current period presentation. The revised amortization amounts for prior periods were not material.

The retrospective application of the adoption of the new accounting guidance for the proportional amortization method resulted in a cumulative effect on retained earnings of a reduction of $195,000.

Basis of Presentation

Our interim consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“U.S. 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 U.S. GAAP. Material estimates subject to change in the near term include, among other items, the allowance for credit losses, the carrying value and useful lives 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. These estimates may be adjusted as more current information becomes available, and any adjustment may be significant.

As described in Note 3, Acquisitions, the acquired assets and liabilities of CapitalSource Inc. 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.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period's presentation format. On the balance sheets, the "Other assets" category includes "FDIC loss sharing asset," which was previously reported as a separate category.

Discontinued operations include the income and expense related to Electronic Payment Services ("EPS"), a discontinued division of the Bank acquired in connection with the First California Financial Group, Inc. ("FCAL") acquisition. Liabilities of the EPS division were $17.0 million and $21.3 million at June 30, 2015 and December 31, 2014, and consisted primarily of noninterest‑bearing deposits, and are included in the condensed consolidated balance sheets under the caption “Accrued interest payable and other liabilities.” For segment reporting purposes, the EPS division is included in our Community Banking segment.

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.

At closing, we created the CapitalSource Division of the Bank. The CapitalSource Division provides a full spectrum of financing solutions across numerous industries and property types to middle market businesses nationwide. 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 lends throughout the United States, providing middle-market businesses asset-secured loans, equipment-secured loans and leases, cash flow loans, and real estate loans secured by various property types.

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 such fair values and accounting for the acquired assets and liabilities. The application of the acquisition method of accounting resulted in goodwill of $1.5 billion. All of the recognized goodwill was non‑deductible for tax purposes.

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 first quarter of 2015, we finalized the estimated fair value of the deferred tax assets acquired in the CapitalSource Inc. merger that resulted in a $7.9 million decrease with a corresponding adjustment to increase goodwill.

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 statements of earnings. No impairment losses were recognized during the six months ended June 30, 2015 and 2014.

CDI and CRI are amortized over their respective estimated useful lives and reviewed for impairment at least quarterly. The amortization expense represents the estimated decline in the value of the underlying deposits or loan and lease customers acquired. The weighted average amortization period remaining for all of our CDI and CRI as of June 30, 2015 is 4.1 years. The aggregate CDI and CRI amortization expense is expected to be $6.0 million for 2015. The estimated aggregate amortization expense related to these intangible assets for each of the next five years is $4.1 million for 2016, $2.3 million for 2017, $2.0 million for 2018, $1.7 million for 2019, and $953,000 for 2020.

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

Notes to Condensed Consolidated Financial Statements (Unaudited)

We reviewed the securities that were in a loss position at June 30, 2015, and concluded their unrealized 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. Although we occasionally sell securities for risk management purposes to reduce risks related to price volatility and duration, we do not foresee having to sell any temporarily impaired securities strictly for liquidity needs and believe that it is more likely than not we would not be required to sell any temporarily impaired 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:

	June 30, 2015
	Amortized		Fair
	Cost		Value
	(In thousands)
Due in one year or less	$	5,783	$	5,810
Due after one year through five years	106,649		108,045
Due after five years through ten years	282,802		291,215
Due after ten years	1,275,557		1,293,088
Total securities available-for-sale	$	1,670,791	$	1,698,158

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, 2015, we had a $17.3 million investment in Federal Home Loan Bank of San Francisco ("FHLB") stock carried at cost. During the six months endedJune 30, 2015, the carrying value of FHLB stock decreased by $23.4 million due to $27.3 million in redemptions, offset partially by $3.9 million in purchases. We evaluated the carrying value of our FHLB stock investment at June 30, 2015, 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. The FHLB paid us a special dividend of $1.4 million in the second quarter of 2015.

Note 6.  Loans and Leases

The Company’s loan and lease portfolio includes originated and purchased loans and leases. Originated loans and leases and purchased loans and leases for which there was no evidence of credit deterioration at their acquisition date and for which it was probable that all contractually required payments would be collected, 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 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 portfolio; 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.

The following table summarizes the composition of our loan and lease portfolio as of the dates indicated:

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 and lease 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.

At June 30, 2015 and December 31, 2014, the Company had no loans and leases (excluding PCI loans) that were greater than 90 days past due and still accruing interest. It is the Company’s policy to discontinue accruing interest when principal or interest payments are past due 90 days or more unless the loan is both well secured and in the process of collection or when, in the judgment of management, there is a reasonable doubt as to the collectability of a loan or lease in the normal course of business. Interest income on nonaccrual loans is recognized only to the extent cash is received and the principal balance of the loan is deemed collectable.

At June 30, 2015, nonaccrual loans and leases totaled $131.2 million and included $33.7 million of loans and leases 90 or more days past due, $4.5 million of loans and leases 30 to 89 days past due, and $93.0 million of current loans and leases that were placed on nonaccrual status based on management’s judgment regarding their collectability. Nonaccrual loans and leases totaled $83.6 million at December 31, 2014, including $18.8 million of loans and leases 90 or more days past due, $8.7 million of loans and leases 30 to 89 days past due, and $56.1 million of current loans and leases that were placed on nonaccrual status based on management’s judgment regarding their collectability. The increase in nonaccrual loans and leases generally, and equipment finance loans and leases specifically, was due to three relationships totaling $64.1 million that are related to the oil and gas industries and which have been adversely impacted by continued low oil prices.

Note 8.  FDIC Loss Sharing Asset

We are a party to four loss sharing agreements with the FDIC. Such agreements cover a substantial portion of losses incurred on acquired covered loans and other real estate owned. The loss sharing agreements relate to the acquisitions of: (1) Affinity Bank ("Affinity") in August 2009, (2) Los Padres Bank ("Los Padres") in August 2010, (3) Western Commercial Bank ("Western Commercial") in connection with the May 2013 FCAL acquisition, and (4) San Luis Trust Bank ("San Luis") in connection with the May 2013 FCAL acquisition. Generally, under the terms of the loss sharing agreements, the FDIC is responsible for 80% of losses in connection with covered assets and is entitled to receive 80% of loss recoveries on the covered assets during the applicable contractual periods. The loss sharing provisions for the Affinity Bank non-single family covered assets expired in the third quarter of 2014; accordingly, further activity will be limited to recoveries through the third quarter of 2017 for assets covered by this loss sharing agreement.

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 "Accrued interest payable and other liabilities" in the condensed consolidated balance sheets.

The following table presents information about the composition of the FDIC loss sharing asset, the true‑up liability, and the non‑single family and the single family covered assets as of the date indicated:

	(Dollars in thousands)
Non‑recourse debt	$	2,751	6.33	%	$	3,402	6.43	%
FHLB overnight advances	—		—	%	380,000		0.27	%
Total borrowings	$	2,751			$	383,402

The non‑recourse debt represents the payment stream of certain equipment leases sold to third parties. The debt is secured by the leased equipment and all interest rates are fixed. As of June 30, 2015, this debt had a weighted average remaining maturity of 2.4 years.

PacWest has an unsecured, variable-rate revolving line of credit in the amount of $75.0 million with an expiration date of September 30, 2015. This borrowing facility provides additional available liquidity to the holding company. As of June 30, 2015 and December 31, 2014, there were no balances outstanding.

The Bank has established secured and unsecured lines of credit under which it may borrow funds from time to time on a term or overnight basis from the FHLB, the Federal Reserve Bank of San Francisco (“FRBSF”), or other financial institutions.

FHLB Secured Lines of Credit. The borrowing arrangement with the FHLB is based on an FHLB program collateralized by a blanket lien on certain qualifying loans that are not pledged to the FRBSF. As of June 30, 2015, the borrowing capacity under the FHLB secured borrowing lines was $2.5 billion and there were no balances outstanding. As of December 31, 2014, the balance outstanding was $380.0 million.

FRBSF Secured Line of Credit. The Bank has a secured line of credit with the FRBSF. As of June 30, 2015, the Bank had secured borrowing capacity of $2.0 billion collateralized by liens covering $2.6 billion of certain qualifying loans. As of June 30, 2015 and December 31, 2014, there were no balances outstanding.

Federal Funds Arrangements with Commercial Banks. As of June 30, 2015, the Bank had unsecured lines of credit of $80.0 million with correspondent banks for the purchase of overnight funds, subject to availability of funds. These lines are renewable annually and have no unused commitment fees. As of June 30, 2015 and December 31, 2014, there were no balances outstanding.

FHLB Unsecured Line of Credit. During the second quarter of 2015, the Bank obtained a $99.0 million unsecured line of credit with the FHLB for the purchase of overnight funds. As of June 30, 2015, there was no balance outstanding.

(2) Amount represents the fair value adjustment on trust preferred securities assumed in acquisitions.

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, are required to notify the FRB prior to declaring and paying a dividend during any period in which quarterly and/or cumulative twelve‑month net earnings are insufficient to fund the dividend amount, among other requirements.

Brokered Time Deposits

Brokered time deposits totaled $645.3 million and $636.7 million at June 30, 2015 and December 31, 2014. Brokered time deposits under the Certificate of Deposit Account Registry Service Program ("CDARS Program") totaled $41.8 million and $44.0 million at June 30, 2015 and December 31, 2014. 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.

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:

	June 30,		December 31,
	2015		2014
	(In thousands)
Loan commitments to extend credit	$	2,111,637	$	1,921,067
Standby letters of credit	104,693		88,495
Commitments to purchase equipment being acquired for lease to others	1,257		12,839
	$	2,217,587	$	2,022,401

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. 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 that call for capital contributions up to an amount specified in the partnership agreements. As of June 30, 2015 and December 31, 2014, the Company had commitments to contribute capital to these entities totaling $17.7 million and $11.0 million, respectively. We also had commitments to contribute up to an additional $2.5 million and $2.9 million to 11 private equity funds at June 30, 2015 and December 31, 2014, respectively.

Legal Matters

In the ordinary course of our business, the Company is 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 currently available information, any resulting liability, in addition to amounts already accrued, would not have a material adverse effect on the Company’s financial statements or operations.

Note 11.  Fair Value Measurements

ASC Topic 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 observable 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 and liabilities on a recurring basis, primarily securities available‑for‑sale and derivatives. 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 tables present information on the assets measured and recorded at fair value on a recurring basis as of the dates indicated:

For information regarding 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), see Note 1 - Nature of Operations and Summary of Significant Accounting Policies and Note 14 - Fair ValueMeasurements to the Consolidated Financial Statements of the Company's 2014 Annual Report on Form 10-K.

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 reasonable 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, 2015, 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, 2015, 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 Bank who remain employed with the Company, and (b) newly hired employees of the Company. As of June 30, 2015, there were 13,205,736 shares available for grant under the 2003 Plan, of which 9,781,278 shares related to those added from the CapitalSource Inc. merger.

Restricted Stock

At June 30, 2015, there were 990,259 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 or immediately upon the death of an employee. Upon closing of the CapitalSource Inc. merger on April 7, 2014, 1,013,377 of awarded shares of restricted common stock vested due to the triggering of the change of control provision contained within the 2003 Plan and a $26.1 million charge to earnings for the vesting of such shares was recorded. Such amount is included in "Acquisition, integration and reorganization costs" on the accompanying condensed consolidated statements of earnings in the second quarter of 2014.

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 $4.4 million, $3.1 million, and $2.4 million for the three months endedJune 30, 2015, March 31, 2015 and June 30, 2014, respectively, and $7.5 million and $4.0 million for the six months endedJune 30, 2015 and 2014, 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, 2015 totaled $38.3 million.

Note 14. Business Segments

The Company’s reportable segments consist of “Community Banking," “National Lending,” and “Other.” The Community Banking and National Lending segments include all of the operations of Pacific Western Bank. The Other segment consists of holding company and non-bank subsidiary operations, and intercompany eliminations.

As a result of the CapitalSource Inc. merger, the Bank established the CapitalSource Division, which we also refer to as the National Lending segment. The National Lending segment includes the lending operations gained through the CapitalSource Inc. merger, Pacific Western Equipment Finance, and the CapitalSource Business Finance Group. We reorganized our asset-based lending and leasing operations when we established the CapitalSource Division.

The CapitalSource Division lends throughout the United States, providing middle-market businesses asset-secured loans, equipment-secured loans, cash flow loans, and real estate loans secured by various property types. The CapitalSource Division’s loan and lease origination efforts are conducted through offices located in Chevy Chase, Maryland; Los Angeles and San Jose, California; Phoenix, Arizona; St. Louis, Missouri; Denver, Colorado; Chicago, Illinois; New York, New York; and Midvale, Utah.

The 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 and corporate overhead.

The Other segment consists of holding company operations that 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 Community Banking segment to the National Lending segment based upon National Lending’s average earning assets, net of a capital allocation, and the Bank’s total cost of deposits. The Community Banking segment further allocates to the National Lending segment noninterest expense for deposit gathering and 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 acquisition, integration and reorganization costs are included in the Community Banking segment. Noninterest income and noninterest expense, including lending and loan servicing activity, directly attributable to a segment are assigned to such segment.

Note 15.  Recently Issued Accounting Standards

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, "Revenue Recognition (Topic 606): Revenue from Contracts with Customers." ASU 2014-09 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.

In June 2014, the FASB issued 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." ASU 2014-12 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.

In January 2015, the FASB issued ASU 2015-01, "Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items," which eliminates the concept of extraordinary items from U.S. GAAP as part of its simplification initiative. Under ASU 2015-01, an entity will no longer separate out an extraordinary item from the results of ordinary operations and separately present this extraordinary item on its income statement, nor will related income tax and earnings-per-share data applicable to an extraordinary item need to be disclosed. Despite these simplifications, ASU 2015-01 does not affect disclosure guidance for events or transactions that are unusual in nature or infrequent in their occurrence. ASU 2015-01 is effective for annual periods beginning after December 15, 2015, and interim periods within those annual periods. The Company does not expect the effect of ASU 2015-01 to have a material impact on its financial statements and related disclosures.

In February 2015, the FASB issued ASU 2015-02, "Consolidation (Topic 810) - Amendments to the Consolidation Analysis," which changes the way reporting enterprises evaluate whether (a) they should consolidate limited partnerships and similar entities, (b) fees paid to a decision maker or service provider are variable interests in a variable interest entity (VIE), and (c) variable interests in a VIE held by related parties of the reporting enterprise require the reporting enterprise to consolidate the VIE. It also eliminates the VIE consolidation model based on majority exposure to variability that applied to certain investment companies and similar entities. ASU 2015-2 is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. The Company does not expect the effect of ASU 2015-02 to have a material impact on its financial statements and related disclosures.

In April 2015, the FASB issued ASU 2015-03, "Interest—Imputation of Interest (Subtopic 835-30) - Simplifying the Presentation of Debt Issuance Costs" to modify the presentation of debt issuance costs.  Prior to ASU 2015-03, issuance costs were presented as an asset on the statement of financial position, which the FASB concluded was inconsistent with both IFRS as well as FASB Concept Statement No. 6. This ASU requires that issuance costs be presented as a direct deduction of debt balances on the statement of financial position, similar to the presentation of debt discounts. ASU 2015-03 is effective for public companies for years beginning after December 15, 2015, and interim periods within those fiscal periods. For all other entities, ASU 2015-03 is effective for years beginning after December 15, 2015 and interim periods within annual periods beginning after December 15, 2016, while early adoption is permitted for financial statements that have not already been issued.  Additionally, the provisions should be applied on a retrospective basis as a change in accounting principle. ASU 2015-03 will not have an impact on the Company's financial statements and related disclosures.

The FASB also issued ASU 2015-05, "Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40), Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement" in April 2015. Under ASU 2015-05, a customer should determine whether the arrangement includes a software license. If so, the customer should account for the software license component in a manner consistent with the accounting for other software licenses. If the arrangement does not include a software license, the arrangement should be accounted for as a service contract. The provisions of ASU 2015-05 must be applied by public entities to annual periods beginning after December 15, 2015 as well as interim periods within those annual periods. The Company does not expect the effect of ASU 2015-05 to have a material impact on its financial statements and related disclosures.

In May 2015, the FASB issued ASU 2015-08, "Business Combinations, Pushdown Accounting (Topic 805), Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 115" which revised the SEC's requirement for recognition and disclosure of a new basis of accounting (or pushdown accounting) for certain business combination situations. The Company does not expect ASU 2015-08 to have any impact on its financial statements and related disclosures.

In June 2015, the FASB issued ASU 2015-10, "Technical Corrections and Improvements" which is a set of wide-ranging, small corrections and improvements to clarify the Codification, correct unintended application of guidance, or improve the Codification. The provisions of ASU 2015-10 are effective for fiscal years beginning after December 15, 2015, as well as interim periods within those fiscal years.

Note 16. Subsequent Events

On August 5, 2015, the Company announced that the Board of Directors had declared a quarterly cash dividend of $0.50 per common share. The cash dividend is payable on August 28, 2015 to stockholders of record at the close of business on August 17, 2015.

We have evaluated events that have occurred subsequent to June 30, 2015 and have concluded there are no subsequent events that would require recognition in the accompanying consolidated financial statements.

Overview

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.” References to “we,” “us,” or the “Company” refer to PacWest Bancorp together with its subsidiaries on a consolidated basis. When we refer to “PacWest” or to the “holding company,” we are referring to PacWest Bancorp, the parent company, on a stand-alone basis. References to “Pacific Western Bank” include the Bank’s wholly owned subsidiaries.

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 and 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 80 full-service branches located primarily in southern and central California. Our branch operations are located primarily in Southern California extending from San Diego County to California’s Central Coast. The Bank also operates three bank branches in the San Francisco Bay area and four bank branches in the Central Valley. The collateral for real estate loan offerings includes healthcare properties, office properties, industrial properties, multifamily properties, hospitality properties, and retail properties.  Our commercial loan products, available on a nationwide basis, include equipment loans and leases, asset based loans, loans to finance companies, and loans secured by borrower future cash flows, as well as other business‑oriented products.

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 lends throughout the United States, providing middle-market businesses asset-secured loans, equipment-secured loans and leases, cash flow loans, and real estate loans secured by various property types. The Bank's leasing operation, Pacific Western Equipment Finance, and its group specializing in asset-based lending, CapitalSource Business Finance Group, are part of the CapitalSource Division. The CapitalSource Division’s loan and lease origination efforts are conducted through key offices located in Chevy Chase, Maryland; Los Angeles and San Jose, California; St. Louis, Missouri; 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 the Bank that specializes in middle-market lending on a nationwide basis.

The Bank competes actively for deposits, and emphasizes solicitation of noninterest‑bearing deposits. In managing the top line of our business, we focus on loan growth, loan yield, deposit cost, and net interest margin. Net interest income, on a year-to-date basis in 2015, accounted for 90.8% of our net revenues (net interest income plus noninterest income).

At June 30, 2015, we had total assets of $16.7 billion, including loans and leases, net of deferred fees, of $12.0 billion compared to $16.2 billion of total assets and $11.9 billion of loans and leases, net of deferred fees, at December 31, 2014. Total assets increased $462.4 million during the six months endedJune 30, 2015 driven by $151.8 million in organic loan and lease growth, which resulted from $1.7 billion in loan and lease production.

At June 30, 2015, we had total liabilities of $13.1 billion, including total deposits of $12.6 billion and borrowings of $2.8 million compared to $12.7 billion of total liabilities, including $11.8 billion of total deposits and $383.4 million of borrowings at December 31, 2014. Total liabilities increased $417.2 million during the six months endedJune 30, 2015 due mainly to the $826.7 million increase in deposits offset by the $380.7 million decrease in borrowings. At June 30, 2015, core deposits totaled $6.6 billion or 52% of total deposits and time deposits totaled $5.3 billion or 43% of total deposits.

Square 1 Financial, Inc. Merger Announcement

On March 2, 2015, PacWest announced the signing of an agreement and plan of merger (the “Agreement”) whereby PacWest and Square 1 Financial, Inc. (“Square 1”) will merge in a transaction currently valued at approximately $867 million. The surviving company will be PacWest Bancorp and the surviving subsidiary bank will be Pacific Western Bank, with the banking operations of Square 1 conducted under the trade name of Square 1 Bank, a division of Pacific Western Bank. The merger with Square 1 represents an opportunity to grow core deposits, expand the Company's nationwide lending platform, and increase the Company's presence in the technology and life-sciences credit markets.

Under the terms of the Agreement, Square 1 stockholders will receive 0.5997 shares of PacWest common stock for each share of Square 1 common stock. The total value of the per share merger consideration is $27.49, based on the $45.84 closing price of PacWest common stock on February 27, 2015, the last trading day before the transaction was announced.

As of June 30, 2015, on a pro forma consolidated basis, after giving effect for the Square 1 merger, the Company would have had approximately $21.1 billion in assets with 80 branches throughout California and one branch in North Carolina.

The transaction, currently expected to close in the fourth quarter of 2015, is subject to customary conditions, including the approval of bank regulatory authorities. The transaction was approved by the Square 1 stockholders on July 29, 2015.

CapitalSource Inc. Merger

On April 7, 2014, we completed the merger with CapitalSource Inc. 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 increase our loan and lease generation capabilities and to diversify our loan portfolio. At closing, we created the CapitalSource Division of the Bank. The CapitalSource Division lends throughout the United States, providing middle-market businesses asset-secured loans, equipment-secured loans and leases, and cash flow loans and providing real estate loans secured by various property types. For further information, see Note 3, Acquisitions, in the Notes to Condensed Consolidated Financial Statements (Unaudited) contained in “Item 1. Condensed Consolidated Financial Statements (Unaudited).”

Key Performance Indicators

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

The Level of Our Net Interest Income

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

Our primary interest‑earning assets are loans and investment securities, and our primary interest‑bearing liabilities are deposits. Contributing to our high net interest margin is our high yield on interest-earning assets and competitive cost of deposits. While our deposit balances will fluctuate depending on deposit holders’ perceptions of alternative yields available in the market, we seek to minimize these variances by attracting a high percentage of noninterest‑bearing deposits. As an industrial loan bank, the former CSB funded its balance sheet with a large proportion of higher-cost time deposits and as a result of the CapitalSource Inc. merger, we added $5.3 billion of time deposits. Our goal is to continue replacing these higher-costing time deposits with core deposits through a dedicated deposit transformation initiative that includes sourcing deposits from CapitalSource Division borrowers. As of June 30, 2015, total deposits obtained from CapitalSource Division borrowers totaled $455.5 million, of which $441.8 million were core deposits.

50

Loan and Lease Growth

We actively seek new lending opportunities under an array of commercial real estate loans and commercial and industrial ("C&I") lending products. Our targeted collateral for our real estate loan offerings includes healthcare properties, office properties, industrial properties, multifamily properties, hospitality properties, and retail properties. Our C&I loan products include equipment-secured loans and leases, asset-secured loans, loans to finance companies, and cash flow loans (which are loans secured by borrower future cash flows and borrower enterprise value). Our loan origination process emphasizes credit quality. We foster lender relationships with borrowers that have had proven loan repayment performance. Our commitment sizes vary by loan product and can range up to $80 million for certain asset-based lending arrangements and multi-property real estate loans. We attempt to price loans to preserve our interest spread and maintain our net interest margin. Achieving net loan growth is subject to many factors, including maintaining strict credit standards, competition from other lenders, and successful borrowers that opt to prepay loans.

The Magnitude of Credit Losses

We emphasize credit quality in originating and monitoring our loans, and we measure our success by the levels of classified and nonperforming assets and net charge‑offs. An allowance for credit losses on loans and leases, which is the sum of our allowance for loan and lease losses and our reserve for unfunded loan commitments, is maintained at a level adequate to cover inherent losses as of the balance sheet date. Provisions for credit losses are charged to operations as and when needed for both on and off‑balance sheet credit exposures. Loans and leases deemed uncollectable are charged off and deducted from the allowance for loan and lease losses. Recoveries on loans and leases previously charged off are added to the allowance for loan and lease losses. The provision for credit losses on the loan and lease portfolio is based on an allowance methodology that considers various credit performance measures such as historical and current net charge‑offs, the levels and trends of nonaccrual and classified loans and leases, the migration of loans and leases into various risk classifications, and the overall level of outstanding loans and leases. For originated and acquired non‑impaired loans, a provision for credit losses may be recorded to reflect credit deterioration after the origination or acquisition date, respectively. For purchased credit impaired ("PCI") loans, a provision for credit losses may be recorded to reflect decreases in expected cash flows on such loans compared to those previously estimated.

We regularly review our loans and leases to determine whether there has been any deterioration in credit quality stemming from borrower operations or changes in collateral value or other factors that may affect collectability of our loans and leases. Changes in economic conditions, such as the rate of economic growth, the rate of inflation, the unemployment rate, increases in the general level of interest rates, declines in real estate values and adverse conditions in borrowers’ businesses, could negatively impact our borrowers and cause us to adversely classify loans and leases. An increase in classified loans and leases generally results in increased provisions for credit losses and an increased allowance for credit losses. Any deterioration in the commercial real estate market may lead to increased provisions for credit losses because of our concentration in commercial real estate loans.

The Level of Our Noninterest Expense

Our noninterest expense includes fixed and controllable overhead, the major components of which are compensation, occupancy, data processing, and other professional services. It also includes costs that tend to vary based on the volume of activity, such as loan production and number and complexity of foreclosed assets. We measure success in controlling both fixed and variable costs through monitoring of the efficiency ratio. We calculate the efficiency ratio by dividing noninterest expense by net revenues (the sum of net interest income plus noninterest income). We also calculate a non‑GAAP measure called the “adjusted efficiency ratio.” The adjusted efficiency ratio is calculated in the same manner as the efficiency ratio except that excluded from net revenues are net FDIC loss sharing expense, gain (loss) on sale of assets, and accelerated discount accretion resulting from early payoffs of acquired loans and excluded from noninterest expense are covered OREO expense and acquisition, integration and reorganization costs.

We present this non-GAAP financial measure and others for supplemental information purposes only in order to understand the Company's operating results and these non-GAAP financial measures should not be considered a substitute for financial information presented in accordance with United States generally accepted accounting principles ("U.S. GAAP").

51

The consolidated efficiency ratios and adjusted efficiency ratios have been as follows for the periods indicated:

		Adjusted
	Efficiency	Efficiency
Three Months Ended	Ratio	Ratio
June 30, 2015	38.4%	40.6%
March 31, 2015	38.4%	40.4%
December 31, 2014	44.0%	41.7%
September 30, 2014	46.3%	43.1%

We disclose the adjusted efficiency ratio as it shows the trend in recurring overhead‑related noninterest expense relative to recurring net revenues. See “Non‑GAAP Measurements” for the calculations of the efficiency ratios and adjusted efficiency ratios.

Adjusted Net Earnings

Our net earnings for the second quarter of 2015 totaled $85.1 million; adjusted net earnings for this same period totaled $72.5 million. Adjusted net earnings is another measure of earnings used as an indicator of earnings generating capability, excluding non-recurring and/or volatile items. We calculate adjusted net earnings by excluding accelerated discount accretion from the early payoff of acquired loans, net FDIC loss sharing expense, gain (loss) on the sale of assets (including loans and leases, securities, and an owned office building), covered OREO expense, and acquisition, integration and reorganization costs. See “-Non‑GAAP Measurements” for a reconciliation of net earnings to adjusted net earnings.

Critical Accounting Policies

The Company’s accounting policies are fundamental to understanding management’s discussion and analysis of results of operations and financial condition. The Company has identified several policies as being critical because they require management to make particularly difficult, subjective and/or complex judgments about matters that are inherently uncertain and because of the likelihood that materially different amounts would be reported under different conditions or using different assumptions. These policies relate to the allowance for credit losses, the fair value estimates of assets acquired and liabilities assumed in acquisitions, the carrying values of intangible assets, and the realization of deferred income tax assets. For further information, refer to our Annual Report on Form 10‑K for the year ended December 31, 2014.

Non-GAAP Measurements

The Company uses certain non‑GAAP financial measures to provide meaningful supplemental information regarding the Company’s operational performance and to enhance investors’ overall understanding of such financial performance. The non-GAAP measures used in this Form 10-Q include the following:

• Adjusted net earnings: To calculate adjusted net earnings, we exclude from net earnings primarily income statement items for which the related assets or liabilities have been completely resolved and are no longer on the balance sheet. As analysts and investors view this measure as an indicator of the Company's ability to generate recurring earnings, we disclose this amount in addition to net earnings.

• Adjusted return on average assets, adjusted return on average equity, return on average tangible equity, adjusted return on average tangible equity, tangible common equity amounts and ratios, and tangible book value per share: Given that the use of these measures is prevalent among banking regulators, investors and analysts, we disclose them in addition to return on average assets, return on average equity, equity-to-assets ratio, and book value per share, respectively.

• Adjusted efficiency ratio: We disclose this measure in addition to the efficiency ratio as it shows the trend in recurring overhead-related noninterest expense relative to recurring net revenues.

• Adjusted allowance for credit losses to loans and leases: As the allowance for credit losses takes into consideration credit deterioration on acquired loans and leases only after the purchase date and an estimate of credit losses is included in their initial fair values, we disclose the adjusted allowance for credit losses to loans and leases in addition to the allowance for credit losses to loans and leases. The adjusted allowance for credit losses to loans and leases excludes acquired loans and leases and the related allowance.

The methodology for determining adjusted net earnings, adjusted return on average assets, adjusted return on average equity, return on average tangible equity, adjusted return on average tangible equity, tangible common equity amounts and ratios, tangible book value per share, adjusted efficiency ratio and adjusted allowance for credit losses to loans and leases may differ among companies.

Results of Operations

Acquisitions Impact Earnings Performance

The comparability of financial information is affected by our acquisitions. We completed the CapitalSource Inc. acquisition on April 7, 2014, adding assets of $9.1 billion. This transaction has been accounted for using the acquisition method of accounting and, accordingly, the related operating results have been included in the consolidated financial statements from its acquisition date.

Second Quarter of 2015 Compared to First Quarter of 2015

Net earnings were $85.1 million, or $0.83 per diluted share for the second quarter of 2015, compared to $73.1 million, or $0.71 per diluted share, for the first quarter of 2014. The quarter‑over‑quarter increase of $12.0 million in net earnings was due to the $9.9 million decrease in the provision for credit losses and higher net interest income of $3.5 million, offset by lower noninterest income of $1.2 million and higher noninterest expense of $0.9 million. The increase in net interest income was attributable to increased FHLB dividends, higher average loan and lease balances, higher accelerated discount accretion and one more day in the second quarter. The decrease in noninterest income was attributed to lower foreign currency translation net gains of $4.0 million and lower gains on sales of securities of $3.5 million, offset by higher dividends and realized gains on equity investments of $4.7 million and higher other commissions and fees of $1.7 million. The increase in noninterest expense was due to higher insurance and assessments expense of $1.7 million, higher compensation expense of $1.3 million and higher loan-related expense of $1.1 million, offset by lower foreclosed assets expense of $2.7 million and lower acquisition, integration and reorganization costs of $1.1 million.

When certain income and expense items are excluded, adjusted net earnings were $72.5 million for the second quarter of 2015 compared to $65.0 million for the prior quarter. See "Non-GAAP Measurements" for the calculation of adjusted net earnings. The $7.5 million increase in adjusted net earnings was driven mainly by a lower provision for credit losses and higher adjusted noninterest income. The higher adjusted net earnings resulted in the adjusted return on average assets increasing from 1.62% to 1.77% and the adjusted return on average tangible equity increasing from 14.69% to 16.11%. The adjusted efficiency ratio increased slightly to 40.60% for the second quarter of 2015 compared to 40.44% for the prior quarter.

Second Quarter of 2015 Compared to Second Quarter of 2014

Net earnings for the second quarter of 2015 were $85.1 million, or $0.83 per diluted share, compared to net earnings for the second quarter of 2014 of $10.6 million, or $0.10 per diluted share. The $74.5 million increase in net earnings was due to higher net interest income of $10.0 million, higher noninterest income of $11.1 million, and lower noninterest expense of $83.9 million, offset by higher income tax expense from continuing operations of $29.7 million and a higher provision for credit losses of $1.5 million. The increase in interest income was attributable to higher average loan and lease balances, higher accelerated discount accretion and increased FHLB dividends. The increase in noninterest income was attributed to higher dividends and realized gains on equity investments of $7.5 million, lower FDIC loss sharing expense of $3.4 million and higher other commissions and fees of $1.4 million, offset by lower foreign currency translation net gains of $1.6 million. The decrease in noninterest expense was due to lower acquisition, integration and reorganization costs of $85.3 million, lower foreclosed assets expense of $2.8 million, and lower loan-related expense of $1.5 million, offset by higher compensation expense of $4.0 million and higher insurance and assessments expense of $1.5 million.

Six Months Ended June 30, 2015 Compared to Six Months Ended June 30, 2014

Net earnings were $158.2 million, or $1.54 per diluted share for the six months endedJune 30, 2015 compared to $35.6 million, or $0.49 per diluted share, for the six months endedJune 30, 2014. The $122.5 million increase in net earnings was due to higher net interest income of $123.1 million, higher noninterest income of $27.3 million, and lower noninterest expense of $49.7 million, offset by higher income tax expense from continuing operations of $60.5 million and a higher provision for credit losses of $18.6 million. The decrease in noninterest expense was due mainly to a reduction in acquisition, integration and reorganization costs of $85.5 million. Excluding this item, all of the changes from period to period were due mostly to including the operations of CapitalSource Inc. for the entire 2015 period compared to only subsequent to its April 7, 2014 acquisition date for the 2014 period.

Net Interest Income

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

The following table presents, for the periods indicated, the distribution of average assets, liabilities and stockholders’ equity, as well as interest income and yields earned on average interest‑earning assets and interest expense and rates paid on average interest‑bearing liabilities presented on a tax equivalent basis:

Second Quarter of 2015 Compared to First Quarter of 2015

Net interest income increased by $3.5 million to $202.6 million for the second quarter of 2015 compared to $199.1 million for the first quarter of 2015 due to increased FHLB dividends, higher average loan and lease balances, higher accelerated discount accretion from early payoffs of acquired loans, and one more day in the second quarter. Interest income includes a special dividend from the FHLB of $1.4 million, which increased our tax equivalent NIM by four basis points.

Our tax equivalent NIM for the second quarter of 2015 was 5.89% compared to 5.95% for the first quarter of 2015, and the loan and lease yield was 6.75% compared to 6.80% for the first quarter of 2015. The decreases in the NIM and loan and lease yield were both due to higher nonaccrual loan and lease average balances in the second quarter, the payoffs of higher-yielding loans and leases and lower discount accretion on acquired loans and leases. The impact on the NIM from accretion of loan and lease acquisition discounts was 82 basis points for the second quarter of 2015 compared to 84 basis points for the first quarter of 2015. The impact on the loan and lease yield from accelerated discount accretion was 64 basis points for the second quarter of 2015 and 58 basis points for the first quarter of 2015. Tax free interest income represented six basis points of the tax equivalent NIM for the second quarter of 2015 and first quarter of 2015.

The cost of total deposits increased to 0.37% from 0.36% in the prior quarter due primarily to a $0.5 million decrease in the amount of premium accretion on the time deposits acquired in the CapitalSource merger. The repricing of maturing time deposits at current rates and new time deposit production resulted in the decline in the weighted average contractual interest rate on time deposits to 0.71% at June 30, 2015 from 0.72% at March 31, 2015.

Second Quarter of 2015 Compared to Second Quarter of 2014

Net interest income increased by $10.0 million to $202.6 million for the second quarter of 2015 compared to $192.5 million for the second quarter of 2014 due mainly to higher average loan and lease balances.

The tax equivalent NIM decreased 40 basis points to 5.89% for the second quarter of 2015 compared to 6.29% for the same quarter last year, due mostly to rates on new originations being lower than the average portfolio rate, the higher-yielding PCI loan portfolio being a smaller percentage of the entire loan portfolio and lower accretion of loan acquisition discounts and time deposit acquisition premiums. The impact on the NIM from accretion of loan and lease acquisition discounts was 82 basis points for the second quarter of 2015 compared to 108 basis points for the second quarter of 2014. Accretion of time deposit acquisition premiums was $0.8 million in the second quarter of 2015 (two basis points on the NIM) compared to $6.7 million in the second quarter of 2014 (22 basis points on the NIM).

The yield on loans and leases decreased 59 basis points to 6.75% for the second quarter of 2015 compared to 7.34% for the same quarter of 2014 due mainly to rates on newly originated loans being lower than the average portfolio rate, the higher-yielding PCI loan portfolio being a smaller percentage of the entire loan portfolio, and the PCI loan yield being lower in the current quarter.

The cost of all funding sources increased nine basis points to 0.50% for the second quarter of 2015 from 0.41% for the second quarter of 2014 due mainly to lower premium accretion on time deposits acquired in the CapitalSource Inc. merger. The all‑in deposit cost increased 11 basis points to 0.37% for the second quarter of 2015 from 0.26% for the same quarter last year. The cost of total interest‑bearing liabilities increased 14 basis points to 0.66% for the second quarter of 2015 from 0.52% for the same quarter last year.

Six Months Ended June 30, 2015 Compared to Six Months Ended June 30, 2014

Net interest income increased by $123.1 million to $401.6 million for the six months endedJune 30, 2015, compared to $278.5 million for the six months endedJune 30, 2014 due to the significant increase in interest-earning assets acquired in the CapitalSource Inc. merger on April 7, 2014.

The tax equivalent NIM decreased 30 basis points to 5.92% for the six months ended June 30, 2015 compared to 6.22% for the same period in 2014, due mostly to lower accretion of loan acquisition discounts and accretion of time deposit acquisition premiums. The impact on the NIM from accretion of loan acquisition discounts was 84 basis points for the six months ended June 30, 2015 compared to 96 basis points for the same period last year. The impact on the NIM from accretion of time deposits acquisition premiums was three basis points for the first six months of 2015 compared to 15 basis points for the same period in 2014. Tax free interest income represented six basis points of the tax equivalent NIM for the six months ended June 30, 2014 and eight basis points for the same period in 2014.

The yield on loans and leases decreased 60 basis points to 6.77% for the first six months of 2015 compared to 7.37% for the same period in 2014 due mainly to lower accretion of loan acquisition discounts. The impact on the loan and lease yield from accretion of loan acquisition discounts was 95 basis points for the six months ended June 30, 2015 compared to 119 basis points for the same period last year. Additionally, this decrease was due to rates on newly originated loans being lower than the average portfolio rate, the higher-yielding PCI loan portfolio representing a smaller percentage of the entire loan portfolio, and the PCI loan yield being lower in the current period.

The cost of all funding sources increased 16 basis points to 0.49% for the six months ended June 30, 2015 from 0.33% for the same period last year due mainly to the $5.3 billion of higher-cost time deposits acquired in the CapitalSource Inc. merger and lower premium accretion on time deposits acquired in the CapitalSource Inc. merger. The all‑in deposit cost increased 15 basis points to 0.36% for the first six months of 2015 from 0.21% for the same period last year. The cost of total interest‑bearing liabilities increased 18 basis points to 0.65% for the six months ended June 30, 2015 from 0.47% for the same period last year.

Allowance for credit losses to Non‑PCI nonaccrual loans
and leases	70.84		%	62.12		%	74.80		%

Provisions for credit losses are charged to earnings for both on and off‑balance sheet credit exposures. We have a provision for credit losses on our Non‑PCI loans and leases and a provision for credit losses on our PCI loans. The provision for credit losses on our Non‑PCI loans and leases is based on our allowance methodology and is an expense, or contra‑expense, that, in our judgment, is required to maintain an adequate allowance for credit losses. Our allowance methodology uses our actual historical loan and lease charge-off experience on pools of similar loans and leases, considers the current credit risk ratings, giving greater weight to loans with more adverse credit risk ratings, and considers subjective criteria such as current economic trends and forecasts, current commercial real estate values and performance trends, and the loan portfolio credit performance trends. The provision for credit losses on our PCI loans results from decreases or increases in expected cash flows on such loans compared to those previously estimated.

We made a provision for credit losses of $6.5 million in the second quarter of 2015 and $16.4 million in the first quarter of 2015 in accordance with our allowance methodology, which takes into consideration new loan and lease fundings, commitments to make loans and leases and underlying credit quality trends. For the Non-PCI portfolio, the $5.0 million provision, combined with net recoveries of $1.4 million, increased the allowance for credit losses by $6.4 million in the second quarter.

Certain circumstances may lead to increased provisions for credit losses in the future. Examples of such circumstances are net loan and lease and unfunded commitment growth, an increased amount of loan and lease charge-offs, changes in economic conditions, such as the rate of economic growth, the rate of inflation, the unemployment rate, increases in the general level of interest rates, declines in real estate values and adverse conditions in borrowers’ businesses.

Second Quarter of 2015 Compared to First Quarter of 2015

Noninterest income decreased by $1.3 million to $19.6 million for the second quarter of 2015 compared to $20.9 million for the first quarter of 2015 due mostly to lower foreign currency translation net gains (losses) and lower gains (losses) on securities offset by higher dividends and realized gains on equity investments and higher other commissions and fees. Foreign currency translation net gains decreased $4.0 million from the prior quarter and are based upon movement of the U.S. Dollar against various foreign currencies, principally the Euro. We hedged our Euro-denominated trust preferred issuance in June 2015 to reduce the related foreign currency translation volatility. The gain on securities was $3.3 million for the first quarter of 2015 compared to a net loss of $0.2 million for the second quarter; all sales related to ongoing portfolio risk management activities. Dividends and realized gains on equity investments tend to fluctuate from period to period based upon actual dividends received and sales activity. The second quarter included the sale of three equity investments at a net gain of $6.0 million; there were no similar sales in the first quarter. The $1.7 million increase in other commissions and fees was due to higher loan prepayment fees and is driven by the level of loan payoff activity.

Second Quarter of 2015 Compared to Second Quarter of 2014

Noninterest income increased by $11.1 million to $19.6 million for the second quarter of 2015 compared to $8.5 million for the second quarter of 2014. The increase was due mostly to higher dividends and realized gains on equity investments of $7.5 million, lower FDIC loss sharing expense of $3.4 million and higher other commissions and fees of $1.4 million, offset by lower foreign currency translation net gains of $1.6 million. The 2015 second quarter included a net gain of $6.0 million on the sale of three equity investments and dividends received of $2.2 million; the 2014 second quarter included a net gain of $0.4 million on the sale of two equity investments and dividends received of $0.3 million. The decrease in FDIC loss sharing expense resulted from a $3.0 million decline in the amortization expense of the FDIC loss sharing asset, as one of the Bank's loss sharing agreements reached the end of its initial indemnification period during the third quarter of 2014. The increase in other commissions and fees was due to higher loan-related unused commitment fees and prepayment fees.

Six Months Ended June 30, 2015 Compared to Six Months Ended June 30, 2014

Noninterest income increased by $27.3 million to $40.5 million for the six months endedJune 30, 2015, compared to $13.2 million for the six months endedJune 30, 2014. The increase was due mostly to income streams gained in the CapitalSource Inc. merger, including higher dividends and realized gains on equity investments of $11.0 million, lower FDIC loss sharing expense of $10.4 million, higher leased equipment income of $5.1 million and higher other commissions and fees of $4.8 million, offset by lower income recognized on early repayment of leases of $2.1 million and lower gains on the sale of securities of $1.8 million. The 2015 period included the sale of three equity investments at a net gain of $6.0 million and dividends received of $5.6 million; the 2014 period included a net gain of $0.4 million on the sale of two equity investments and dividends received of $0.3 million. The decrease in FDIC loss sharing expense resulted from a $6.9 million decline in the amortization expense of the FDIC loss sharing asset, as one of the Bank's loss sharing agreements reached the end of its initial indemnification period during the third quarter of 2014; a $2.2 million decrease in the loss on the FDIC loss sharing asset; and a $1.4 million decrease in net reimbursement expense to the FDIC for covered OREO's. The increase in other commissions and fees was due to higher loan-related unused commitment fees and prepayment fees.

Second Quarter of 2015 Compared to First Quarter of 2015

Noninterest expense increased by $0.9 million to $85.3 million for the second quarter of 2015 compared to $84.4 million for the first quarter of 2015. The increase was due mostly to higher insurance and assessments expense of $1.7 million, higher compensation expense of $1.3 million and higher loan-related expense of $1.1 million, offset by lower foreclosed assets expense of $2.7 million and lower acquisition, integration and reorganization costs of $1.1 million. Insurance and assessments expense increased due to the FDIC deposit insurance assessment being calculated under the “large-bank” method starting in the second quarter of 2015. Compensation expense increased due to higher stock-based compensation expense, employee pay raises that took effect towards the end of the first quarter of 2015 and higher incentive compensation accruals. Loan-related expense increased due to lower recoveries of legal costs specifically and lower loan-related expenses generally. The first quarter of 2015 included a $1.7 million recovery of legal costs compared to a $0.6 million recovery in the second quarter related to the same matter. Foreclosed assets expense decreased due to higher operating income related to foreclosed assets sales in the second quarter. Acquisition, integration and reorganization costs will fluctuate from period to period based on the timing and amount of such activities.

Second Quarter of 2015 Compared to Second Quarter of 2014

Noninterest expense decreased by $83.9 million to $85.3 million for the second quarter of 2015 compared to $169.2 million for the second quarter of 2014. The decrease in noninterest expense was due to lower acquisition, integration and reorganization costs of $85.3 million, lower foreclosed assets expense of $2.8 million, and lower loan-related expense of $1.5 million, offset by higher compensation expense of $4.0 million and higher insurance and assessments expense of $1.5 million. Foreclosed assets expense declined due to higher operating income related to foreclosed assets sales in the second quarter of 2015. Compensation expense increased due to higher stock-based compensation expense and higher incentive accruals in the second quarter of 2015. Insurance and assessments expense increased due to the FDIC insurance assessment being calculated under the “large-bank” method starting in the second quarter of 2015. The acquisition, integration and reorganization costs for the second quarter of 2015 related to the pending Square 1 Financial, Inc. merger, while these costs for the second quarter of 2014 related to the CapitalSource Inc. merger.

Six Months Ended June 30, 2015 Compared to Six Months Ended June 30, 2014

Noninterest expense decreased by $49.7 million to $169.6 million for the six months endedJune 30, 2015 compared to $219.4 million for the six months endedJune 30, 2014. The decrease in noninterest expense was due mainly to lower acquisition, integration and reorganization costs of $85.5 million. Excluding this item, all of the changes from period to period were due mostly to including the operations of CapitalSource Inc. subsequent to its April 7, 2014 acquisition date. The acquisition, integration and reorganization costs for the six months ended June 30, 2015 related to the pending Square 1 Financial, Inc. merger, while these costs for the same period last year related to the CapitalSource Inc. merger.

Income Taxes

The effective tax rate for the second quarter of 2015 was 34.7% compared to 38.7% for the first quarter of 2015 and 58.8% for the second quarter of 2014. The decline in the effective rate in the second quarter of 2015 is related to utilization of a portion of the capital loss carryforward and adjustments to certain deferred tax assets. The Company operates primarily in the states of California and Maryland and the blended statutory tax rate for federal and states is 41%. We expect that our effective tax rate will be 38% for 2015 and 39% for 2016.

Business Segments

The Company’s reportable segments consist of “Community Banking,” “National Lending,” and “Other.” The Community Banking and National Lending segments include all of the operations of Pacific Western Bank. The Other segment consists of holding company and non-bank subsidiary operations, and intercompany eliminations.

As a result of the CapitalSource Inc. merger, the Bank established the CapitalSource Division, which we also refer to as the National Lending segment. The National Lending segment includes the lending operations gained through the CapitalSource Inc. merger, Pacific Western Equipment Finance, and the CapitalSource Business Finance Group. We reorganized our asset-based lending and leasing operations when we established the CapitalSource Division.

The CapitalSource Division lends throughout the United States, providing middle-market businesses asset-secured loans, equipment-secured loans, cash flow loans, and real estate loans secured by various property types. The CapitalSource Division’s loan and lease origination efforts are conducted through offices located in Chevy Chase, Maryland; Los Angeles and San Jose, California; Phoenix, Arizona; St. Louis, Missouri; Denver, Colorado; Chicago, Illinois; New York, New York; and Midvale, Utah.

The 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 and corporate overhead.

The Other segment consists of holding company operations that 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.

Second Quarter of 2015 Compared to Second Quarter of 2014

Net earnings for the Community Banking segment increased $46.6 million for the second quarter of 2015 to $16.5 million, compared to a net loss of $30.2 million in the second quarter of 2014. Net earnings before taxes increased $67.8 million as a result of lower noninterest expense-adjusted of $98.7 million and higher noninterest income of $3.7 million, offset by higher provision for credit losses of $3.7 million and lower net interest income of $7.3 million. The decrease in noninterest expense-adjusted is due mostly to lower acquisition, integration and reorganization costs of $76.9 million. The increase in noninterest income is due to lower FDIC loss sharing expense of $3.4 million during the second quarter of 2015 when compared to the second quarter of 2014. Net interest income decreased compared to the prior year period due to lower average loan and lease balances and a lower loan and lease yield.

Net earnings for the National Lending segment increased $16.3 million for the second quarter of 2015 to $62.1 million, compared to $45.8 million for the second quarter of 2014. The increase in net earnings is a result of increased interest-earning assets and the related increase in net interest income of $19.0 million. Loans increased $1.3 billion to $8.9 billion as of June 30, 2015 from $7.6 billion as of June 30, 2014.

Six Months Ended June 30, 2015 Compared to Six Months Ended June 30, 2014

Net earnings for the Community Banking segment increased $51.4 million for the six months endedJune 30, 2015 to $43.2 million compared to a net loss of $8.2 million for the six months endedJune 30, 2014. Net earnings before taxes increased $75.6 million primarily as a result of lower noninterest expense-adjusted of $64.0 million. The decrease in noninterest expense-adjusted is due mostly to lower acquisition, integration and reorganization costs of $77.2 million.

Net earnings for the National Lending segment increased $58.0 million for the six months ended June 30, 2015 to $108.4 million compared to net earnings of $50.4 million for the six months ended June 30, 2014. The increase in earnings is a result of the CapitalSource Inc. merger that increased interest-earning assets and net interest income. Loans and leases increased $8.0 billion to $8.5 billion at the beginning of the 2015 period from $474.9 million at the beginning of the 2014 period.

Our real estate portfolio exposes us to risk elements associated with mortgage loans on commercial property. Commercial real estate mortgage loan repayments typically do not rely on the sale of the underlying collateral, but instead rely on the income producing potential of the collateral as the source of repayment. Ultimately, though, due to the loan amortization period generally being greater than the contractual loan term, the borrower may be required to refinance the loan, either with us or another lender, or pay off the loan, by selling the underlying collateral. Our commercial-related real estate loans do not expose us to risks generally associated with residential mortgage loans such as option ARM, interest-only, or subprime mortgage loans.

Credit Exposure Affected by Low Oil Prices

At June 30, 2015, we had 29 outstanding loan and lease relationships totaling $177.2 million to borrowers and lessees primarily involved in the oil and gas industry as compared to $181.5 million at March 31, 2015. The obligors under these loans and leases either conduct oil and gas extraction or provide industrial support services to such types of businesses. The collateral for these loans and leases primarily includes equipment, such as drilling and mining equipment and transportation vehicles, used directly and indirectly in these activities. At June 30, 2015, four relationships totaling $64.2 million were on nonaccrual status and were classified.

Allowance for Credit Losses on Non-PCI Loans and Leases

The allowance for credit losses on non-purchased credit impaired ("Non-PCI") loans and leases is the combination of the allowance for loan and lease losses and the reserve for unfunded loan commitments. The allowance for loan and lease losses is reported as a reduction of outstanding loan and lease balances and the reserve for unfunded loan commitments is included within "Accrued interest payable and other liabilities." The following discussion is for Non-PCI loans and leases and the allowance for credit losses thereon. Refer to "Balance Sheet Analysis - Allowance for Credit Losses on PCI Loans" for the policy on PCI loans. For loans and leases acquired and measured at fair value and deemed non-impaired on the acquisition date, our allowance methodology measures deterioration in credit quality or other inherent risks related to these acquired assets that may occur after the acquisition date.

The allowance for loan and lease losses is maintained at a level deemed appropriate by management to adequately provide for known and inherent risks in the loan and lease portfolio and other extensions of credit at the balance sheet date. The allowance is based upon our continual review of the credit quality of the loan and lease portfolio, which includes loan and lease payment trends, borrowers' compliance with loan agreements, borrowers' current and budgeted financial performance, collateral valuation trends, and current economic factors and external conditions that may affect our borrowers' ability to pay. Loans and leases that are deemed to be uncollectable are charged off and deducted from the allowance. The provision for loan and lease losses and recoveries on loans and leases previously charged off are added to the allowance.

The allowance for loan and lease losses contains a general reserve component for loans and leases with no credit impairment and a specific reserve component for loans and leases determined to be impaired.

76

A loan or lease is considered impaired when it is probable that we will be unable to collect all amounts due according to the original contractual terms of the agreement. We assess our loans for impairment on an ongoing basis using certain criteria such as payment performance, borrower reported financial results and budgets, and other external factors when appropriate. We measure impairment of a loan based upon the fair value of the loan’s collateral if the loan is collateral-dependent or the present value of cash flows, discounted at the loan’s effective interest rate, if the loan is not collateral-dependent. We measure impairment of a lease based upon the present value of the scheduled lease and residual cash flows, discounted at the lease's effective interest rate. To the extent a loan or lease balance exceeds the estimated collectable value, a specific reserve or charge-off is recorded depending upon the certainty of the estimate of loss. Smaller balance loans (under $250,000), with a few exceptions for certain loan types, are generally not individually assessed for impairment but are evaluated collectively.

The methodology we use to estimate the general reserve component of our allowance for credit losses considers both quantitative and qualitative criteria. The quantitative criteria uses our actual historical loan and lease charge-off experience on pools of similar loans and leases to establish loss factors that are applied to our current loan and lease balances to estimate inherent credit losses. When estimating the general reserve component for the various pools of similar loan types, the loss factors applied to the loan pools consider the current credit risk ratings, giving greater weight to loans with more adverse credit risk ratings. We recognize that the determination of the allowance for loan and lease losses is sensitive to the assigned credit risk ratings and inherent loss rates at any given point in time. To ensure the accuracy of our credit risk ratings, an independent credit review function assesses the ratings assigned to loans on an ongoing basis.

The qualitative criteria considered when establishing the loss factors include the following:

• current economic trends and forecasts;

• current commercial real estate values, performance trends, and overall outlook in the markets where we lend;

• legal and regulatory matters that could impact our borrowers’ ability to repay our loans;

• our loan portfolio composition and any loan concentrations;

• our current lending policies and the effects of any new policies or policy amendments;

• our new loan origination volume and the nature of it;

• our loan portfolio credit performance trends; and

• the results of our ongoing independent credit review.

The reserve for unfunded commitments is estimated using the same loss factors as used for the allowance for loan and lease losses and is computed based only on the expected usage of the unfunded commitments.

The credit risk ratings assigned to every loan and lease are either “pass,” “special mention,” “substandard” or “doubtful” and defined as follows:

• Pass: Loans and leases classified as "pass" are not adversely classified and collection and repayment in full are expected.

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

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

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

In addition, we may refer to the loans and leases classified as "substandard" and "doubtful" together as "classified" loans and leases. For further information on classified loans and leases, see Note 6, Loans and Leases, of the Notes to Condensed Consolidated Financial Statements (Unaudited) contained in "Item 1. Condensed Consolidated Financial Statements (Unaudited)."

77

Management believes that the allowance for credit losses is appropriate for the known and inherent risks in our Non-PCI loan and lease portfolio and that the credit risk ratings and inherent loss rates currently assigned are appropriate. It is possible that others, given the same information, may at any point in time reach different conclusions that could result in a significant impact to the Company's financial statements. In addition, current credit risk ratings are subject to change as we continue to monitor our loans and leases. To the extent we experience, for example, increased levels of documentation deficiencies, adverse changes in collateral values, or negative changes in economic and business conditions that adversely affect our borrowers, our classified loans and leases may increase. Higher levels of classified loans and leases generally result in increased provisions for credit losses and an increased allowance for credit losses. Although we have established an allowance for credit losses that we consider appropriate, there can be no assurance that the established allowance will be sufficient to absorb related losses in the future.

The following table presents information regarding the allowance for credit losses on Non-PCI loans and leases as of the dates indicated:

	June 30,			March 31,			December 31,			June 30,

See "Balance Sheet Analysis - Nonperforming Assets and Performing Restructured Loans" for information regarding the increase in our nonaccrual loans and leases during the six months ended June 30, 2015.

All acquired loans are recorded initially at their estimated fair value with such initial fair value including an estimate of credit losses. Two additional credit coverage ratios shown in the table below are presented to give an indication of overall credit risk coverage:

The first additional credit coverage ratio calculation makes adjustments for acquired loans and leases and the related allowance. Our Non‑PCI loans and leases at June 30, 2015, included $5.6 billion in loans and leases acquired in acquisitions. These acquired loans and leases were initially recorded at their estimated fair values and such initial fair values included an estimate of credit losses. The allowance calculation for Non‑PCI loans and leases takes into consideration those acquired loans and leases whose credit quality has deteriorated since their acquisition dates. At June 30, 2015, our allowance for credit losses included $12.7 million related to these acquired loans and leases. When these acquired loans and leases are excluded from the total of Non‑PCI loans and leases and the related allowance is excluded from the allowance for credit losses, the result is an adjusted coverage ratio of our allowance for credit losses to Non‑PCI loans and leases of 1.28% at June 30, 2015. At March 31, 2015, this ratio was 1.32%.

78

The second additional credit coverage ratio calculation makes an adjustment for the unamortized purchase discount on acquired loans and leases. Our acquired Non-PCI loans and leases included an unamortized purchase discount of $103.3 million at June 30, 2015, which is assigned specifically to those loans and leases only. Such discount represents the acquisition date fair value adjustment based on market, liquidity, interest rate and credit risk. When the unamortized purchase discount is added back to our Non-PCI loans and leases and allowance for credit losses, the result is an adjusted coverage ratio of our allowance for credit losses to Non-PCI loans and leases of 1.64% at June 30, 2015. At March 31, 2015, this ratio was 1.79%.

The unamortized purchase discount is being accreted to interest income over the remaining life of the respective loans and leases using the interest method. Use of the interest method results in steadily declining amounts being taken into income in each reporting period. Assuming all of these loans and leases continue to make payments according to their terms and there are no prepayments and no deterioration in credit quality, the remaining discount of $103.3 million at June 30, 2015 is expected to be fully accreted to income by the end of 2018.

Allowance for Credit Losses on PCI Loans

The PCI loans are subject to our internal and external credit review. For PCI loans, the allowance for loan losses is measured at the end of each financial reporting period based on expected cash flows. Decreases or (increases) in the amount and changes in the timing of expected cash flows on the PCI loans as of the financial reporting date compared to those previously estimated are usually recognized by recording a provision or a (negative provision) for credit losses on such loans. If deterioration in the expected cash flows results in a reserve requirement, a provision for credit losses is charged to earnings.

The following table presents the changes in our allowance for credit losses on PCI loans for the periods indicated:

(1) Represents legacy CapitalSource Inc. borrowing relationships placed on nonaccrual status as of the acquisition date.

(2) Excludes PCI loans.

Nonperforming assets include Non-PCI and PCI nonaccrual loans and leases and foreclosed assets and totaled $168.9 million at June 30, 2015 compared to $198.6 million at March 31, 2015. The $29.7 million decrease in nonperforming assets was due to a $25.5 million decrease in nonaccrual loans and leases and a $4.3 million decrease in foreclosed assets. The ratio of nonperforming assets to loans and leases and foreclosed assets decreased to 1.40% at June 30, 2015 from 1.61% at March 31, 2015.

Nonaccrual Loans and Leases

The $25.5 million decrease in nonaccrual loans and leases during the second quarter of 2015 was attributable to $30.0 million in principal payments and other reductions offset by $4.5 million in additions.

Performing Restructured Loans

Non-PCI performing restructured loans increased by $2.2 million during the second quarter of 2015 to $38.2 million at June 30, 2015. The increase was attributable primarily to $4.9 million in additions, offset partially by $2.4 million in payoffs. At June 30, 2015, we had $23.9 million in real estate mortgage loans, $7.7 million in real estate construction and land loans, $6.4 million in commercial loans, and $0.2 million in consumer loans that were accruing interest under the terms of troubled debt restructurings.

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

PCI Delinquent and Nonaccrual Loans

Loans accounted for as PCI are generally considered accruing and performing loans as the loans accrete their discount to interest income over the estimated life of the loan when cash flows are reasonably estimable. Accordingly, PCI loans that are contractually past due are still considered to be accruing and performing loans. If the timing and amount of future cash flows is not reasonably estimable, the loans are classified as nonaccrual loans and interest income is not recognized until the timing and amount of future cash flows can be reasonably estimated. As of June 30, 2015, there are $6.0 million of PCI loans on nonaccrual status and included in the delinquency table below.

The following table presents a summary of the borrowers' underlying payment status of PCI loans as of the dates indicated:

Regulatory Matters

Capital

Bank regulatory agencies measure capital adequacy through standardized risk-based capital guidelines that compare different levels of capital (as defined by such guidelines) to risk-weighted assets and off-balance sheet obligations. At June 30, 2015, Banks and bank holding companies considered to be “well capitalized” must maintain a minimum Tier 1 leverage ratio of 5.00%, a minimum common equity Tier 1 risk-based capital ratio of 6.50%, a minimum Tier 1 risk-based capital ratio of 8.00%, and a minimum total risk-based capital ratio of 10.00%. Regulatory capital requirements limit the amount of deferred tax assets that may be included when determining the amount of regulatory capital. Deferred tax asset amounts in excess of the calculated limit are disallowed from regulatory capital. At June 30, 2015, such disallowed amount was $56.1 million for the Company and none were disallowed for the Bank. No assurance can be given that the regulatory capital deferred tax asset limitation will not increase in the future or that the Company or Bank will not have increased deferred tax assets that are disallowed.

In July 2013, the Company’s primary federal regulator, the FRB, and the Bank’s primary federal regulator, the FDIC, approved final rules (the “New Capital Rules”) establishing a new comprehensive capital framework for U.S. banking organizations. The New Capital Rules generally implement the Basel Committee on Banking Supervision’s December 2010 final capital framework referred to as “Basel III” for strengthening international capital standards. The New Capital Rules required under Basel III were effective for the Company and the Bank on January 1, 2015, subject to phase-in periods for certain of their components and other provisions. As expected, the most significant of the provisions of the New Capital Rules which applied to the Company and the Bank were as follows: the phase-out of trust preferred securities from Tier 1 capital, the higher risk-weighting of high volatility and past due real estate loans and the capital treatment of deferred tax assets and liabilities above certain thresholds.

The following table presents our regulatory capital ratios and the regulatory capital requirements under Basel III:

	June 30, 2015
	Pacific		PacWest		Well
	Western		Bancorp		Capitalized
	Bank		Consolidated		Requirement
Tier 1 Leverage	11.65	%	11.96	%	5.00	%
Common Equity Tier-1 Capital	12.55		12.87		6.50
Tier 1 Capital	12.55		12.87		8.00
Total Capital	13.35		16.53		10.00

Subordinated Debentures

The Company issued subordinated debentures to trusts that were established by us or entities we have acquired, which, in turn, issued trust preferred securities. The amount of subordinated debentures totaled $433.9 million at June 30, 2015. At June 30, 2015, $32.8 million of the trust preferred securities was included in the Company's Tier I capital and $389.7 million was included in Tier II capital.

Dividends on Common Stock and Interest on Subordinated Debentures

Bank holding companies, such as PacWest, are required to notify the Board of Governors of the Federal Reserve System (“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. Interest payments made by the Company on subordinated debentures are considered dividend payments under FRB regulations.

Liquidity

Liquidity Management

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

The Company manages its liquidity by maintaining pools of liquid assets on-balance sheet, consisting of cash and due from banks, interest-earning deposits in other financial institutions and unpledged investment securities available-for-sale, which we refer to as our primary liquidity. In addition, we also maintain available borrowing capacity under secured borrowing lines with the FHLB and the Federal Reserve Bank of San Francisco (“FRBSF”), which we refer to as our secondary liquidity. In addition to its secured lines of credit, the Bank also maintains unsecured lines of credit, subject to availability, of $80.0 million with correspondent banks for the purchase of overnight funds and $99.0 million with FHLB for the purchase of overnight funds.

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

Total secondary liquidity	$	4,458,681		$	3,280,595		$	3,316,807

During the three months ended June 30, 2015, the Bank’s primary liquidity increased $342.0 million due to a $180.1 million increase in interest-earning deposits in financial institutions, a $102.7 million increase in investment securities available-for-sale, and a $68.7 million increase in cash and due from banks, offset by a $9.6 million increase in pledged investment securities available-for-sale. The Bank’s secondary liquidity increased $1.2 billion during the second quarter due to a $615.0 million decrease in FHLB secured advances outstanding, a $440.1 million increase in the secured credit line with the FRBSF and a $123.0 million increase in the borrowing capacity on the secured credit line with the FHLB, due to increased in loans pledged as collateral on those facilities.

86

At June 30, 2015, $2.6 billion of certain qualifying loans were specifically pledged as collateral for the secured borrowing line maintained with the FRBSF. The FHLB borrowing lines are secured by a blanket lien on certain qualifying loans that are not pledged to the FRBSF.

In addition to our primary liquidity, we generate liquidity from cash flows from our amortizing loan and securities portfolios and from our large base of core customer deposits, defined as noninterest-bearing demand, interest checking, savings and money market accounts. At June 30, 2015, such deposits totaled $6.6 billion and represented 52% of the Bank's total deposits. These core deposits are normally less volatile, often with customer relationships tied to other products offered by the Company promoting long-standing relationships and stable funding sources.

Deposits from our customers may decrease if interest rates increase significantly or if corporate customers move funds from the Bank generally. In order to address the Bank’s liquidity risk as deposit balances may fluctuate, the Bank maintains adequate levels of available liquidity.

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

Total core deposits	$	6,584,606	$	6,197,400	$	6,135,577

Our liquidity policy establishes various liquidity guidelines for the Bank. The policy includes guidelines for On-Balance Sheet Liquidity (a measurement of primary liquidity to total deposits plus borrowings), Coverage and Crisis Coverage Ratios (measurements of liquid assets to expected short-term liquidity required for the loan and deposit portfolios under normal and stressed conditions), Loan to Funding Ratio (measurement of gross loans net of fees divided by deposits plus FHLB borrowings), Wholesale Funding Ratio (measurement of wholesale funding divided by interest-earning assets), and other guidelines developed for measuring and maintaining liquidity. As of June 30, 2015, we were in compliance with all liquidity guidelines established in the liquidity policy.

We use brokered deposits, the availability of which is uncertain and subject to competitive market forces, for liquidity management purposes. At June 30, 2015, brokered deposits totaled $1.3 billion, consisting of $603.5 million of brokered time deposits, $651.9 million of non-maturity brokered sweep accounts, $41.8 million of CDARS Program deposits, and $16.4 million of other miscellaneous brokered deposits. At December 31, 2014, brokered deposits totaled $776.5 million, consisting of $592.7 million of brokered time deposits, $120.6 million of non-maturity brokered sweep accounts, $44.0 million of CDARS Program deposits, and $19.1 million of other miscellaneous brokered deposits, 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. The amount of our brokered deposits has increased in recent quarters because of favorable market conditions for brokered deposits compared to retail time deposits we obtain from the Bank's branch network and the large amount of deposits that can be obtained in a short period of time to manage liquidity and funding needs.

Holding Company Liquidity

The primary sources of liquidity for the holding company include dividends from the Bank and our ability to raise capital, issue subordinated debt and secure outside borrowings. Our ability to obtain funds for the payment of dividends to our stockholders and for other cash requirements is largely dependent upon the Bank’s earnings. The Bank is subject to restrictions under certain federal and state laws and regulations that limit its ability to transfer funds to the holding company through intercompany loans, advances or cash dividends.

87

Dividends paid by state banks, such as the Bank, are regulated by the California Department of Business Oversight (“DBO”) under its general supervisory authority as it relates to a bank’s capital requirements and the FDIC. A state bank may declare a dividend without the approval of the DBO and the FDIC as long as the total dividends declared in a calendar year do not exceed either the retained earnings or the total of net profits for three previous fiscal years less any dividends paid during such period. During the three and six months endedJune 30, 2015, PacWest received $40.0 million and $95.0 million in dividends from the Bank. For the foreseeable future, any dividends from the Bank to the holding company require DBO and FDIC approval.

At June 30, 2015, PacWest had $419.0 million in cash, of which the majority is on deposit at the Bank. We believe this amount of cash, along with anticipated dividends from the Bank, will be sufficient to fund the holding company's cash flow needs over the next 12 months.

On October 1, 2014, the holding company obtained an unsecured, variable-rate revolving line of credit in the amount of $75 million with an expiration date of September 30, 2015. This borrowing facility provides additional available liquidity to the holding company.

_______________________________________

(1) Excludes purchase accounting fair value adjustments.

(2) Excludes interest on subordinated debentures as these instruments are variable rate.

Long-term debt obligations include subordinated debentures. Debt obligations are also discussed in Note 9, Borrowings, Subordinated Debentures and Brokered Deposits, in the Notes to Condensed Consolidated Financial Statements (Unaudited) contained in “Item 1. Condensed Consolidated Financial Statements (Unaudited).” Operating lease obligations are discussed in the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2014. The other contractual obligations relate to our minimum liability associated with our data and item processing contract with a third-party provider and commitments to contribute capital to investments in low income housing project partnerships and private equity funds.

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

Off-Balance Sheet Arrangements

Our obligations also include off-balance sheet arrangements consisting of loan and lease-related commitments, of which only a portion is expected to be funded. At June 30, 2015, our loan and lease-related commitments, including standby letters of credit, totaled $2.2 billion. The commitments, which may result in funded loans and leases, increase our profitability through net interest income. We manage our overall liquidity taking into consideration funded and unfunded commitments as a percentage of our liquidity sources. Our liquidity sources have been and are expected to be sufficient to meet the cash requirements of our lending activities.

Asset/Liability Management and Interest Rate Sensitivity

Interest Rate Risk

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

We evaluated the results of our net interest income simulation and market value of equity models prepared as of June 30, 2015, the results of which are presented below. Our net interest income simulation indicates that our balance sheet is asset sensitive. An asset sensitive profile would suggest that a sudden sustained increase in rates would result in an increase in our estimated net interest income and market value of equity, while a liability sensitive profile would suggest that these amounts would decrease. In general, we view the net interest income model results as more relevant to the Company’s current operating profile and manage our balance sheet giving priority to this information.

Net Interest Income Simulation

We used a simulation model to measure the estimated changes in net interest income that would result over the next 12 months from immediate and sustained changes in interest rates as of June 30, 2015. This model is an interest rate risk management tool and the results are not necessarily an indication of our future net interest income. This model has inherent limitations and these results are based on a given set of rate changes and assumptions at one point in time. We have assumed no growth in either our total interest‑sensitive assets or liabilities over the next 12 months; therefore, the results reflect an interest rate shock to a static balance sheet.

This analysis calculates the difference between net interest income forecasted using both increasing and declining interest rate scenarios using the forward yield curve at June 30, 2015. In order to arrive at the base case, we extend our balance sheet at June 30, 2015 one year and reprice any assets and liabilities that would contractually reprice or mature during that period using the products’ pricing as of June 30, 2015. Based on such repricing, we calculate an estimated net interest income and net interest margin.

The repricing relationship for each of our assets and liabilities includes many assumptions. For example, many of our assets are variable‑rate loans, which are assumed to reprice in accordance with their contractual terms. Some loans and investment vehicles include the opportunity of prepayment (imbedded options) and the simulation model uses prepayment assumptions to estimate these prepayments and reinvest these proceeds at current simulated yields. Our deposit products reprice at our discretion and are assumed to reprice more slowly in a rising or declining interest rate environment and usually reprice at a rate less than the change in market rates. The effects of certain balance sheet attributes, such as fixed‑rate loans, variable‑rate loans that have reached their floors, the 4.00% floor we have administered on the Bank's base lending rate (affecting $520 million of variable-rate loans originated by the Community Banking segment tied to this index), and the volume of noninterest‑bearing deposits as a percentage of earning assets, impact our assumptions and consequently the results of our interest rate risk management model. Changes that could vary significantly from our assumptions include loan and deposit growth or contraction, changes in the mix of our earning assets or funding sources, and future asset/liability management decisions, all of which may have significant effects on our net interest income.

89

The following table presents as of June 30, 2015, forecasted net interest income and net interest margin for the next 12 months using a base market interest rate and the estimated change to the base scenario given immediate and sustained upward and downward movements in interest rates of 100, 200 and 300 basis points:

					Estimated
	Estimated		Percentage	Estimated	Net Interest
June 30, 2015	Net Interest		Change	Net Interest	Margin Change
Interest Rate Scenario:	Income		From Base	Margin	From Base
	(Dollars in millions)
Up 300 basis points	$	820.0	11.5%	5.75%	0.58%
Up 200 basis points	$	784.9	6.7%	5.51%	0.34%
Up 100 basis points	$	754.6	2.6%	5.30%	0.13%
BASE CASE	$	735.5	—	5.17%	—
Down 100 basis points	$	740.2	0.6%	5.20%	0.03%
Down 200 basis points	$	741.1	0.8%	5.21%	0.04%
Down 300 basis points	$	741.7	0.8%	5.21%	0.04%

Total base case year 1 net interest income decreased slightly to $735.5 million at June 30, 2015 from $736.4 at March 31, 2015. The net interest income ("NII") simulation model prepared as of June 30, 2015 suggests our balance sheet is asset sensitive. The degree of asset sensitivity in the second quarter’s NII rate shock results decreased slightly compared to the prior quarter primarily due to adjustments made to deposit pricing beta assumptions, which we monitor and adjust on an ongoing basis.

Although $9.1 billion of the $12.1 billion of total loans in the portfolio have variable interest rate terms, only $2.3 billion of those variable-rate loans would immediately reprice at June 30, 2015 under the modeled scenarios. Of the remaining variable-rate loans, $6.1 billion would not immediately reprice because the loans' fully-indexed rates are below their floor rates. Of these $6.1 billion of loans at their floors, the fully-indexed rates would rise off of the floors and reprice as follows:

June 30, 2015
		Rate
Cumulative		Increase
Amount of		Needed to
Loans		Reprice
(Dollars in millions)
$	5,457.4	100 bps
$	5,821.7	200 bps
$	5,948.8	300 bps

Additionally, certain variable-rate hybrid ARM loans do not immediately reprice because the loans contain an initial fixed-rate period before they become adjustable. The cumulative amounts of hybrid ARM loans that would switch from being fixed-rate to variable-rate, because the initial fixed-rate term would expire, was approximately $141.0 million, $304.0 million, and $495.0 million in the next one, two, and three years.

Market Value of Equity

We measure the impact of market interest rate changes on the net present value of estimated cash flows from our assets, liabilities and off-balance sheet items, defined as the market value of equity, using a simulation model. This simulation model assesses the changes in the market value of our interest-sensitive financial instruments that would occur in response to an instantaneous and sustained increase or decrease in market interest rates of 100, 200, and 300 basis points. This analysis assigns significant value to our noninterest-bearing deposit balances. The projections are by their nature forward-looking and therefore inherently uncertain, and include various assumptions regarding cash flows and interest rates.

This model is an interest rate risk management tool and the results are not necessarily an indication of our actual future results. Actual results may vary significantly from the results suggested by the market value of equity table. Loan prepayments and deposit attrition, changes in the mix of our earning assets or funding sources, and future asset/liability management decisions, among others, may vary significantly from our assumptions. The base case is determined by applying various current market discount rates to the estimated cash flows from the different types of assets, liabilities and off-balance sheet items existing at June 30, 2015.

The following table shows the projected change in the market value of equity for the set of rate scenarios presented as of June 30, 2015:

										Ratio of
	Estimated		Dollar			Percentage		Percentage		Estimated
June 30, 2015	Market		Change			Change		of Total		Market Value
Interest Rate Scenario:	Value		From Base			From Base		Assets		to Book Value
	(Dollars in millions)
Up 300 basis points	$	4,450.9	$	158.5		3.7	%	26.7	%	125.3	%
Up 200 basis points	$	4,407.0	$	114.6		2.7	%	26.4	%	124.1	%
Up 100 basis points	$	4,352.2	$	59.8		1.4	%	26.1	%	122.5	%
BASE CASE	$	4,292.4	$	—		—		25.7	%	120.9	%
Down 100 basis points	$	4,236.4	$	(56.0	)	(1.3	)%	25.4	%	119.3	%
Down 200 basis points	$	4,138.7	$	(153.7	)	(3.6	)%	24.8	%	116.5	%
Down 300 basis points	$	4,066.5	$	(225.9	)	(5.3	)%	24.4	%	114.5	%

In comparing the June 30, 2015 simulation results to March 31, 2015, our base case estimated market value of equity has increased while our overall profile has remained relatively unchanged. Base case market value of equity increased $391 million compared to March 31, 2015. This increase was due mostly to revised modeling assumptions used to model the decay rates of our non-maturity deposits, which resulted in longer weighted average lives than were previously assumed in the model.

Market Risk - Foreign Currency Exchange

The Company enters into foreign exchange contracts with its clients and counterparty banks primarily for the purpose of offsetting or hedging clients' transaction and economic exposures arising out of commercial transactions. We have experienced and will continue to experience fluctuations in our net income as a result of transaction gains or losses related to revaluing certain asset and liability balances that are denominated in currencies other than the U.S. Dollar. We recognized foreign currency gains of $1.2 million and $0.3 million for the six months ended June 30, 2015 and 2014, respectively. In June 2015, we hedged our Euro-denominated trust preferred issuance to reduce the related foreign currency translation volatility.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Please see the section above titled "Asset/Liability Management and Interest Rate Sensitivity" in "Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations" which provides an update to our quantitative and qualitative disclosure about market risk. This analysis should be read in conjunction with text under the caption "Quantitative and Qualitative Disclosure About Market Risk" in our Annual Report on Form 10-K for the year ended December 31, 2014, which text is incorporated herein by reference. Our analysis of market risk and market-sensitive financial information contains forward-looking statements and is subject to the disclosure at the beginning of Item 2 regarding such forward-looking information.

ITEM 4. CONTROLS AND PROCEDURES

As of the end of the period covered by this report, an evaluation was carried out by the Company's management, with the participation of the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the Company's disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, these disclosure controls and procedures were effective.

There have been no changes in the Company's internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

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, taking into consideration insurance which may be applicable, would not have a material adverse effect on the Company’s financial statements or operations.

ITEM 1A. RISK FACTORS

For information regarding factors that could affect the Company's results of operations, financial condition and liquidity, see the risk factors disclosed in the "Risk Factors" section of our Annual Report on Form 10-K for the year ended December 31, 2014.

[1] (1)During the second quarter of 2015, two loan relationships, consisting of five loans and leases adversely affected by low oil prices, were restructured to reduce the current payment amounts for a period of time. These loans were assessed for impairment during the first quarter of 2015 and a specific credit loss allowance was established. These loans were on nonaccrual status before and after the restructuring.

Our commercial loan products include equipment loans and leases, asset-based loans, loans to finance companies, 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 lends throughout the United States, providing middle-market businesses asset-secured loans, equipment-secured loans and leases, cash flow loans, and real estate loans secured by various property types. The Bank's leasing operation, Pacific Western Equipment Finance, and its group specializing in asset-based lending, CapitalSource Business Finance Group, are 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; St. Louis, Missouri; 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 the 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 include 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, 2015, including the acquisition of CapitalSource Inc. 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 consolidated financial statements from their respective acquisition dates. See Note 3, Acquisitions, for more information about the CapitalSource Inc. merger.

Square 1 Financial, Inc. Merger Announcement

On March 2, 2015, PacWest announced the signing of an agreement and plan of merger (the “Agreement”) whereby PacWest and Square 1 Financial, Inc. (“Square 1”) will merge in a transaction currently valued at approximately $867 million. The surviving company will be PacWest Bancorp and the surviving subsidiary bank will be Pacific Western Bank, with the banking operations of Square 1 conducted under the trade name of Square 1 Bank, a division of Pacific Western Bank.

Under the terms of the Agreement, Square 1 stockholders will receive 0.5997 shares of PacWest common stock for each share of Square 1 common stock. The total value of the per share merger consideration is $27.49, based on the $45.84 closing price of PacWest common stock on February 27, 2015, the last trading day before the transaction was announced.

As of June 30, 2015, on a pro forma consolidated basis, after giving effect to the Square 1 merger, the Company would have had approximately $21.1 billion in assets with 80 branches throughout California and one branch in North Carolina.

The transaction, currently expected to close in the fourth quarter of 2015, is subject to customary conditions, including the approval of bank regulatory authorities. The transaction was approved by the Square 1 stockholders on July 29, 2015.

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, 2014 as filed with the Securities and Exchange Commission ("Form 10-K").

Accounting Standard Adopted in 2015

Effective January 1, 2015, the Company adopted new accounting guidance for investments in affordable housing projects that qualify for the low-income housing tax credit. As a result of the adoption of this new guidance, the Company made an accounting policy election to amortize the initial cost of its qualifying investments in proportion to the tax credits and other benefits received and to present the amortization as a component of income tax expense, referred to as the proportional amortization method. Previously, investments in low-income housing tax credits were accounted for under the equity method and such amortization was presented in other expense. The guidance was required to be applied retrospectively and accordingly, prior period amounts for other expense and tax expense have been revised to conform to the current period presentation. The revised amortization amounts for prior periods were not material.

The retrospective application of the adoption of the new accounting guidance for the proportional amortization method resulted in a cumulative effect on retained earnings of a reduction of $195,000.

Basis of Presentation

Our interim consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“U.S. 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 U.S. GAAP. Material estimates subject to change in the near term include, among other items, the allowance for credit losses, the carrying value and useful lives 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. These estimates may be adjusted as more current information becomes available, and any adjustment may be significant.

As described in Note 3, Acquisitions, the acquired assets and liabilities of CapitalSource Inc. 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.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period's presentation format. On the balance sheets, the "Other assets" category includes "FDIC loss sharing asset," which was previously reported as a separate category.

Recently Issued Accounting Standards [Abstract]

New Accounting Pronouncements and Changes in Accounting Principles

Recently Issued Accounting Standards

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, "Revenue Recognition (Topic 606): Revenue from Contracts with Customers." ASU 2014-09 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.

In June 2014, the FASB issued 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." ASU 2014-12 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.

In January 2015, the FASB issued ASU 2015-01, "Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items," which eliminates the concept of extraordinary items from U.S. GAAP as part of its simplification initiative. Under ASU 2015-01, an entity will no longer separate out an extraordinary item from the results of ordinary operations and separately present this extraordinary item on its income statement, nor will related income tax and earnings-per-share data applicable to an extraordinary item need to be disclosed. Despite these simplifications, ASU 2015-01 does not affect disclosure guidance for events or transactions that are unusual in nature or infrequent in their occurrence. ASU 2015-01 is effective for annual periods beginning after December 15, 2015, and interim periods within those annual periods. The Company does not expect the effect of ASU 2015-01 to have a material impact on its financial statements and related disclosures.

In February 2015, the FASB issued ASU 2015-02, "Consolidation (Topic 810) - Amendments to the Consolidation Analysis," which changes the way reporting enterprises evaluate whether (a) they should consolidate limited partnerships and similar entities, (b) fees paid to a decision maker or service provider are variable interests in a variable interest entity (VIE), and (c) variable interests in a VIE held by related parties of the reporting enterprise require the reporting enterprise to consolidate the VIE. It also eliminates the VIE consolidation model based on majority exposure to variability that applied to certain investment companies and similar entities. ASU 2015-2 is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. The Company does not expect the effect of ASU 2015-02 to have a material impact on its financial statements and related disclosures.

In April 2015, the FASB issued ASU 2015-03, "Interest—Imputation of Interest (Subtopic 835-30) - Simplifying the Presentation of Debt Issuance Costs" to modify the presentation of debt issuance costs.  Prior to ASU 2015-03, issuance costs were presented as an asset on the statement of financial position, which the FASB concluded was inconsistent with both IFRS as well as FASB Concept Statement No. 6. This ASU requires that issuance costs be presented as a direct deduction of debt balances on the statement of financial position, similar to the presentation of debt discounts. ASU 2015-03 is effective for public companies for years beginning after December 15, 2015, and interim periods within those fiscal periods. For all other entities, ASU 2015-03 is effective for years beginning after December 15, 2015 and interim periods within annual periods beginning after December 15, 2016, while early adoption is permitted for financial statements that have not already been issued.  Additionally, the provisions should be applied on a retrospective basis as a change in accounting principle. ASU 2015-03 will not have an impact on the Company's financial statements and related disclosures.

The FASB also issued ASU 2015-05, "Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40), Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement" in April 2015. Under ASU 2015-05, a customer should determine whether the arrangement includes a software license. If so, the customer should account for the software license component in a manner consistent with the accounting for other software licenses. If the arrangement does not include a software license, the arrangement should be accounted for as a service contract. The provisions of ASU 2015-05 must be applied by public entities to annual periods beginning after December 15, 2015 as well as interim periods within those annual periods. The Company does not expect the effect of ASU 2015-05 to have a material impact on its financial statements and related disclosures.

In May 2015, the FASB issued ASU 2015-08, "Business Combinations, Pushdown Accounting (Topic 805), Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 115" which revised the SEC's requirement for recognition and disclosure of a new basis of accounting (or pushdown accounting) for certain business combination situations. The Company does not expect ASU 2015-08 to have any impact on its financial statements and related disclosures.

In June 2015, the FASB issued ASU 2015-10, "Technical Corrections and Improvements" which is a set of wide-ranging, small corrections and improvements to clarify the Codification, correct unintended application of guidance, or improve the Codification. The provisions of ASU 2015-10 are effective for fiscal years beginning after December 15, 2015, as well as interim periods within those fiscal years.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

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:

	June 30,		December 31,
	2015		2014
	(In thousands)
Loan commitments to extend credit	$	2,111,637	$	1,921,067
Standby letters of credit	104,693		88,495
Commitments to purchase equipment being acquired for lease to others	1,257		12,839
	$	2,217,587	$	2,022,401

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. 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 that call for capital contributions up to an amount specified in the partnership agreements. As of June 30, 2015 and December 31, 2014, the Company had commitments to contribute capital to these entities totaling $17.7 million and $11.0 million, respectively. We also had commitments to contribute up to an additional $2.5 million and $2.9 million to 11 private equity funds at June 30, 2015 and December 31, 2014, respectively.

Legal Matters

In the ordinary course of our business, the Company is 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 currently available information, any resulting liability, in addition to amounts already accrued, would not have a material adverse effect on the Company’s financial statements or operations.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

ASC Topic 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 observable 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 and liabilities on a recurring basis, primarily securities available‑for‑sale and derivatives. 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 tables present information on the assets measured and recorded at fair value on a recurring basis as of the dates indicated:

For information regarding 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), see Note 1 - Nature of Operations and Summary of Significant Accounting Policies and Note 14 - Fair ValueMeasurements to the Consolidated Financial Statements of the Company's 2014 Annual Report on Form 10-K.

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 reasonable 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, 2015, the amounts that will actually be realized or paid at settlement or maturity of the instruments could be significantly different.

We reviewed the securities that were in a loss position at June 30, 2015, and concluded their unrealized 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. Although we occasionally sell securities for risk management purposes to reduce risks related to price volatility and duration, we do not foresee having to sell any temporarily impaired securities strictly for liquidity needs and believe that it is more likely than not we would not be required to sell any temporarily impaired 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:

	June 30, 2015
	Amortized		Fair
	Cost		Value
	(In thousands)
Due in one year or less	$	5,783	$	5,810
Due after one year through five years	106,649		108,045
Due after five years through ten years	282,802		291,215
Due after ten years	1,275,557		1,293,088
Total securities available-for-sale	$	1,670,791	$	1,698,158

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, 2015, we had a $17.3 million investment in Federal Home Loan Bank of San Francisco ("FHLB") stock carried at cost. During the six months endedJune 30, 2015, the carrying value of FHLB stock decreased by $23.4 million due to $27.3 million in redemptions, offset partially by $3.9 million in purchases. We evaluated the carrying value of our FHLB stock investment at June 30, 2015, 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. The FHLB paid us a special dividend of $1.4 million in the second quarter of 2015.

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Intangible Assets Disclosure

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 first quarter of 2015, we finalized the estimated fair value of the deferred tax assets acquired in the CapitalSource Inc. merger that resulted in a $7.9 million decrease with a corresponding adjustment to increase goodwill.

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 statements of earnings. No impairment losses were recognized during the six months ended June 30, 2015 and 2014.

CDI and CRI are amortized over their respective estimated useful lives and reviewed for impairment at least quarterly. The amortization expense represents the estimated decline in the value of the underlying deposits or loan and lease customers acquired. The weighted average amortization period remaining for all of our CDI and CRI as of June 30, 2015 is 4.1 years. The aggregate CDI and CRI amortization expense is expected to be $6.0 million for 2015. The estimated aggregate amortization expense related to these intangible assets for each of the next five years is $4.1 million for 2016, $2.3 million for 2017, $2.0 million for 2018, $1.7 million for 2019, and $953,000 for 2020.

FDIC Loss-Sharing Arrangements [Abstract]

FDIC Loss Sharing Asset Disclosure

FDIC Loss Sharing Asset

We are a party to four loss sharing agreements with the FDIC. Such agreements cover a substantial portion of losses incurred on acquired covered loans and other real estate owned. The loss sharing agreements relate to the acquisitions of: (1) Affinity Bank ("Affinity") in August 2009, (2) Los Padres Bank ("Los Padres") in August 2010, (3) Western Commercial Bank ("Western Commercial") in connection with the May 2013 FCAL acquisition, and (4) San Luis Trust Bank ("San Luis") in connection with the May 2013 FCAL acquisition. Generally, under the terms of the loss sharing agreements, the FDIC is responsible for 80% of losses in connection with covered assets and is entitled to receive 80% of loss recoveries on the covered assets during the applicable contractual periods. The loss sharing provisions for the Affinity Bank non-single family covered assets expired in the third quarter of 2014; accordingly, further activity will be limited to recoveries through the third quarter of 2017 for assets covered by this loss sharing agreement.

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 "Accrued interest payable and other liabilities" in the condensed consolidated balance sheets.

The following table presents information about the composition of the FDIC loss sharing asset, the true‑up liability, and the non‑single family and the single family covered assets as of the date indicated:

Receivables [Abstract]

Loans and Credit Quality

Loans and Leases

The Company’s loan and lease portfolio includes originated and purchased loans and leases. Originated loans and leases and purchased loans and leases for which there was no evidence of credit deterioration at their acquisition date and for which it was probable that all contractually required payments would be collected, 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 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 portfolio; 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.

The following table summarizes the composition of our loan and lease portfolio as of the dates indicated:

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 and lease 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.

At June 30, 2015 and December 31, 2014, the Company had no loans and leases (excluding PCI loans) that were greater than 90 days past due and still accruing interest. It is the Company’s policy to discontinue accruing interest when principal or interest payments are past due 90 days or more unless the loan is both well secured and in the process of collection or when, in the judgment of management, there is a reasonable doubt as to the collectability of a loan or lease in the normal course of business. Interest income on nonaccrual loans is recognized only to the extent cash is received and the principal balance of the loan is deemed collectable.

The following table presents our nonaccrual and performing Non‑PCI loans and leases by portfolio segment and class as of the dates indicated:

At June 30, 2015, nonaccrual loans and leases totaled $131.2 million and included $33.7 million of loans and leases 90 or more days past due, $4.5 million of loans and leases 30 to 89 days past due, and $93.0 million of current loans and leases that were placed on nonaccrual status based on management’s judgment regarding their collectability. Nonaccrual loans and leases totaled $83.6 million at December 31, 2014, including $18.8 million of loans and leases 90 or more days past due, $8.7 million of loans and leases 30 to 89 days past due, and $56.1 million of current loans and leases that were placed on nonaccrual status based on management’s judgment regarding their collectability. The increase in nonaccrual loans and leases generally, and equipment finance loans and leases specifically, was due to three relationships totaling $64.1 million that are related to the oil and gas industries and which have been adversely impacted by continued low oil prices.

Segment Reporting [Abstract]

Segment Data

Business Segments

The Company’s reportable segments consist of “Community Banking," “National Lending,” and “Other.” The Community Banking and National Lending segments include all of the operations of Pacific Western Bank. The Other segment consists of holding company and non-bank subsidiary operations, and intercompany eliminations.

As a result of the CapitalSource Inc. merger, the Bank established the CapitalSource Division, which we also refer to as the National Lending segment. The National Lending segment includes the lending operations gained through the CapitalSource Inc. merger, Pacific Western Equipment Finance, and the CapitalSource Business Finance Group. We reorganized our asset-based lending and leasing operations when we established the CapitalSource Division.

The CapitalSource Division lends throughout the United States, providing middle-market businesses asset-secured loans, equipment-secured loans, cash flow loans, and real estate loans secured by various property types. The CapitalSource Division’s loan and lease origination efforts are conducted through offices located in Chevy Chase, Maryland; Los Angeles and San Jose, California; Phoenix, Arizona; St. Louis, Missouri; Denver, Colorado; Chicago, Illinois; New York, New York; and Midvale, Utah.

The 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 and corporate overhead.

The Other segment consists of holding company operations that 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 Community Banking segment to the National Lending segment based upon National Lending’s average earning assets, net of a capital allocation, and the Bank’s total cost of deposits. The Community Banking segment further allocates to the National Lending segment noninterest expense for deposit gathering and 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 acquisition, integration and reorganization costs are included in the Community Banking segment. Noninterest income and noninterest expense, including lending and loan servicing activity, directly attributable to a segment are assigned to such segment.

The following tables present information regarding our business segments as of and for the periods indicated:

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.

At closing, we created the CapitalSource Division of the Bank. The CapitalSource Division provides a full spectrum of financing solutions across numerous industries and property types to middle market businesses nationwide. 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 lends throughout the United States, providing middle-market businesses asset-secured loans, equipment-secured loans and leases, cash flow loans, and real estate loans secured by various property types.

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 such fair values and accounting for the acquired assets and liabilities. The application of the acquisition method of accounting resulted in goodwill of $1.5 billion. All of the recognized goodwill was non‑deductible for tax purposes.

_________________________

(1) During the second quarter of 2015, two loan relationships, consisting of five loans and leases adversely affected by low oil prices, were restructured to reduce the current payment amounts for a period of time.  These loans were assessed for impairment during the first quarter of 2015 and a specific credit loss allowance was established. These loans were on nonaccrual status before and after the restructuring.
