Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	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.

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.

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 .

These amounts are included in "Acquisition, integration and reorganization costs" in the condensed consolidated statements of earnings.

In addition, we sold $323.6 million of the $382.8 million of securities obtained in the CapitalSource Inc. merger for no gain or loss.

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 ended June 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.

Loans and Credit Quality

Loans and Credit Quality	6 Months Ended

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.

Our regulators may require the Company to recognize rating downgrades based on their judgments related to information available to them at the time of their examinations. Risk rating downgrades generally result in higher allowances for credit losses.

FDIC Loss-Sharing 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.

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: Fair Value Measurements as of June 30, 2015 Measured on a Recurring Basis: Total Level 1 Level 2 Level 3 (In thousands) Securities available‑for‑sale: Government agency and government‑sponsored enterprise pass-through securities $ 426,874 $ — $ 426,874 $ — Government agency and government‑sponsored enterprise collateralized mortgage obligations 265,899 — 265,899 — Covered private label CMOs 32,323 — — 32,323 Other private label CMOs 8,025 — 8,025 — Municipal securities 721,556 — 721,556 — Corporate debt securities 47,410 — 47,410 — Collateralized loan obligations 133,907 — 133,907 — Government‑sponsored enterprise debt securities 37,080 — 37,080 — Other securities 25,084 518 24,566 — Total securities available-for-sale 1,698,158 518 1,665,317 32,323 Derivative assets 8,810 — 8,810 — Total recurring assets $ 1,706,968 $ 518 $ 1,674,127 $ 32,323 Derivative liabilities $ 725 $ — $ 725 $ — Fair Value Measurements as of December 31, 2014 Measured on a Recurring Basis: Total Level 1 Level 2 Level 3 (In thousands) Securities available‑for‑sale: Government agency and government‑sponsored enterprise pass-through securities $ 535,672 $ — $ 535,672 $ — Government agency and government‑sponsored enterprise collateralized mortgage obligations 277,946 — 277,946 — Covered private label CMOs 33,947 — — 33,947 Other private label CMOs 10,914 — 10,914 — Municipal securities 536,116 — 536,116 — Corporate debt securities 110,109 — 110,109 — Government‑sponsored enterprise debt securities 36,757 — 36,757 — Other securities 25,716 519 25,197 — Total securities available-for-sale 1,567,177 519 1,532,711 33,947 Derivative assets 5,234 — 5,234 — Total recurring assets $ 1,572,411 $ 519 $ 1,537,945 $ 33,947 Derivative liabilities $ 118 $ — $ 118 $ — There were no transfers of assets either between Level 1 and Level 2 nor in or out of Level 3 of the fair value hierarchy for assets measured on a recurring basis during the six months ended June 30, 2015 .

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.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Based Compensation Plans	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 ended June 30, 2015 , March 31, 2015 and June 30, 2014 , respectively, and $7.5 million and $4.0 million for the six months ended June 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 .

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: June 30, 2015 Community National Consolidated Balance Sheet Data: Banking Lending Other Company (In thousands) Loans and leases, net of deferred fees $ 3,101,834 $ 8,923,079 $ 9,276 $ 12,034,189 Allowance for loan and lease losses (41,108 ) (58,260 ) (7 ) (99,375 ) Total loans and leases, net $ 3,060,726 $ 8,864,819 $ 9,269 $ 11,934,814 Goodwill $ 333,979 $ 1,394,401 $ — $ 1,728,380 Core deposit and customer relationship intangibles, net 13,528 673 — 14,201 Total assets 6,685,456 9,870,154 141,410 16,697,020 Total deposits (1) 12,962,905 35,420 (416,509 ) 12,581,816 ________________________ (1) The negative balance for total deposits in the “Other” segment represents the elimination of holding company cash held in deposit accounts at the Bank.

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.

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.
