ITEM 1.    BUSINESS  

General  

PART I  

        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 banking subsidiary, Pacific Western Bank, which we refer to as Pacific Western or the Bank. When we say 
"we", "our" or the "Company", we mean the Company on a consolidated basis with the Bank. When we refer to "PacWest" or to the holding 
company, we are referring to the parent company on a stand-alone basis.  

        PacWest Bancorp was formerly known as First Community Bancorp. At a special meeting of the Company's shareholders held on April 23, 
2008, the shareholders approved the reincorporation of the Company in Delaware from California and the change of the Company's name to 
PacWest Bancorp from First Community Bancorp. The reincorporation became effective on May 14, 2008. In connection with the reincorporation 
and name change, the Company also changed its ticker symbol on the NASDAQ Global Select Market to "PACW." Other than the name change, 
change in ticker symbol and change in corporate domicile, the reincorporation did not result in any change in the business, physical location, 
management, assets, liabilities or total stockholders' equity of the Company, nor did it result in any change in location of the Company's 
employees, including the Company's management. Additionally, the reincorporation did not alter any shareholder's percentage ownership interest 
or number of shares owned in the Company.  

Recent Transactions  

        In January 2012, Pacific Western Bank acquired Marquette Equipment Finance, or MEF, an equipment leasing company, for $35 million in cash. 
At January 3, 2012, MEF had $162.2 million in gross leases and leases in process outstanding, with no leases on nonaccrual status. In addition, 
Pacific Western Bank assumed $154.8 million in outstanding debt and other liabilities, which included $129 million payable to MEF's former parent. 
Pacific Western Bank repaid MEF's intercompany debt on the closing date from its excess liquidity on deposit at the Federal Reserve Bank.  

        See "—Strategic Evolution and Acquisition Strategy", "Item 7. Management's Discussion and Analysis of Financial Condition and Results of 
Operations—Overview", and Note 3, Acquisitions, Note 4, Goodwill and Other Intangible Assets, Note 6, Loans, and Note 23, Subsequent Events, 
of the Notes to Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data" for further information 
regarding recent transactions.  

Banking Business  

        Pacific Western is a full-service commercial bank offering a broad range of banking products and services including: accepting demand, 
money market, and time deposits; originating loans, including commercial, real estate construction, real estate miniperm, SBA guaranteed and 
consumer loans; and providing other business-oriented products. We have 76 full-service community banking branches. Our operations are 
primarily located in Southern California extending from California's Central Coast to San Diego County; we also operate three banking offices in the 
San Francisco Bay area, all of which were added through the Affinity acquisition. The Bank focuses on conducting business with small to medium 
size businesses in our marketplace and the owners and employees of those businesses. The majority of our loans are secured by the real estate 
collateral of such businesses. Our asset-based lending function operates in Arizona, California, Texas, and the Pacific Northwest. Our equipment 
leasing function, added through the January 2012 MEF acquisition, operates in Utah and has lease receivables in 45 states. Special services, 
including international banking services, multi-state deposit  

3 

 
 
 
Table of Contents 

services and investment services, or requests beyond the service area or current offerings of the Bank can be arranged through correspondent 
banks. The Bank also issues ATM and debit cards, has a network of branded ATMs and offers access to ATM networks through other major 
service providers. We provide access to customer accounts via a 24-hour seven day a week toll-free automated telephone customer service and a 
secure online banking service.  

        We are committed to maintaining premier, relationship-based community banking in Southern California serving the needs of those businesses 
in our marketplace, as well as serving the needs of growing businesses that may not yet meet the credit standards of the Bank, through tightly 
controlled asset-based lending and factoring of accounts receivable. We compete actively for deposits, and emphasize solicitation of noninterest-
bearing deposits. In managing the top line of our business, we focus on making quality loans and gathering low-cost deposits to maximize our net 
interest margin. The strategy for serving our target markets is the delivery of a finely-focused set of value-added products and services that satisfy 
the primary needs of our customers, emphasizing superior service and relationships over transaction volume or low pricing.  

        We generate our revenue primarily from the interest received on the various loan products and investment securities and fees from providing 
deposit services, foreign exchange services and extending credit. Our major operating expenses are the interest paid by the Bank on deposits and 
borrowings, employee compensation and general operating expenses. The Bank relies on a foundation of locally generated and relationship-based 
deposits to fund loans. Our Bank has a relatively low cost of funds due to a high percentage of noninterest-bearing and low cost deposits to total 
deposits. Our operations, similar to other financial institutions with operations predominately focused in Southern California, are significantly 
influenced by economic conditions in Southern California, including the strength of the real estate market, the fiscal and regulatory policies of the 
federal and state governments and the regulatory authorities that govern financial institutions. See "—Supervision and Regulation." Through our 
offices located in Northern California, our asset-based lending operations with production and marketing offices located in Arizona, Northern 
California, and the Pacific Northwest, and our equipment leasing operations located in Utah, we are also subject to the economic conditions 
affecting these markets.  

Lending Activities  

        Through the Bank, the Company concentrates its lending activities in four principal areas:  

        (1)    Real Estate Loans.    Real estate loans are comprised of construction loans, miniperm loans collateralized by first or junior deeds of trust 
on specific commercial properties and equity lines of credit. The properties collateralizing real estate loans are principally located in our primary 
market areas of Los Angeles, Orange, San Bernardino, Riverside, San Diego, Ventura, Santa Barbara and San Luis Obispo counties in California 
and the neighboring communities. Construction loans are comprised of loans on commercial, residential and income producing properties that 
generally have terms of less than two years and typically bear an interest rate that floats with the Bank's base rate or another established index. 
Miniperm loans finance the purchase and/or ownership of commercial properties, including owner-occupied and income producing properties. 
Miniperm loans are generally made with an amortization schedule ranging from 15 to 25 years with a lump sum balloon payment due in one to ten 
years. Equity lines of credit are revolving lines of credit collateralized by junior deeds of trust on residential real properties. They generally bear a 
rate of interest that floats with the Bank's base rate or the prime rate and have maturities of ten years. From time to time, we purchase participation 
interests in loans originated by other financial institutions. These loans are subject generally to the same underwriting criteria and approval 
process as loans originated directly by us.  

        The Bank's real estate portfolio is subject to certain risks, including, but not limited to: (i) the effects of economic downturns in the Southern 
California economy and in general; (ii) interest rate  

4 

Table of Contents 

increases; (iii) reduction in real estate values in Southern California and in general; (iv) increased competition in pricing and loan structure; (v) the 
borrower's ability to refinance or payoff the balloon or line of credit at maturity; and (vi) environmental risks, including natural disasters. In 
addition to the foregoing, construction loans are also subject to project specific risks including, but not limited to: (a) construction costs being 
more than anticipated; (b) construction taking longer than anticipated; (c) failure by developers and contractors to meet project specifications; 
(d) disagreement between contractors, subcontractors and developers; (e) demand for completed projects being less than anticipated; (f) buyers 
being unable to secure financing; and (g) loss through foreclosure.  

        When underwriting loans, we strive to reduce the exposure to such risks by (i) reviewing each loan request and renewal individually, (ii) using 
a dual signature approval system for the approval of each loan request for loans over a certain dollar amount, (iii) adhering to written loan policies, 
including, among other factors, minimum collateral requirements, maximum loan-to-value ratio requirements, cash flow requirements and personal 
guarantees, (iv) obtaining independent third party appraisals which are reviewed by the Bank's appraisal department, (v) obtaining external 
independent credit reviews, (vi) evaluating concentrations as a percentage of capital and loans, and (vii) conducting environmental reviews, where 
appropriate. With respect to construction loans, in addition to the foregoing, we attempt to mitigate project specific risks by: (a) implementing a 
controlled disbursement process for loan proceeds in accordance with an agreed upon schedule; (b) conducting project site visits; and 
(c) adhering to release-price schedules to ensure the prices for which newly-built units to be sold are sufficient to repay the Bank. The risks related 
to buyer inability to secure financing and loss through foreclosure are not controllable. We review each loan request on the basis of our ability to 
recover both principal and interest in view of the inherent risks.  

        (2)    Commercial Loans.    Commercial loans, both domestic and foreign, are made to finance operations, to provide working capital, or for 
specific purposes such as to finance the purchase of assets, equipment or inventory. Since a borrower's cash flow from operations is generally the 
primary source of repayment, our policies provide specific guidelines regarding required debt coverage and other important financial ratios. 
Commercial loans include lines of credit and commercial term loans. Lines of credit are extended to businesses or individuals based on the financial 
strength and integrity of the borrower and guarantor(s) and generally (with some exceptions) are collateralized by short-term assets such as 
accounts receivable, inventory, equipment or real estate and have a maturity of one year or less. Such lines of credit bear an interest rate that floats 
with the Bank's base rate, LIBOR or another established index. Commercial term loans are typically made to finance the acquisition of fixed assets, 
refinance short-term debt originally used to purchase fixed assets or, in rare cases, to finance the purchase of businesses. Commercial term loans 
generally have terms from one to five years. They may be collateralized by the asset being acquired or other available assets and bear interest rates 
which either float with the Bank's base rate, LIBOR or another established index or remain fixed for the term of the loan.  

        The Bank's portfolio of commercial loans is subject to certain risks, including, but not limited to: (i) the effects of economic downturns in the 
Southern California economy; (ii) interest rate increases; (iii) deterioration of the value of the underlying collateral; and (iv) the deterioration of a 
borrower's or guarantor's financial capabilities. We strive to reduce the exposure to such risks through: (a) reviewing each loan request and 
renewal individually; (b) using a dual signature approval system; (c) adhering to written loan policies; (d) obtaining external independent credit 
reviews, and (e) in the case of certain commercial loans to Mexican or foreign entities, third party insurance which limits our exposure to anywhere 
from 20 to 30 percent of the underlying loan. In addition, loans based on short-term asset values and factoring arrangements are monitored on a 
daily, weekly, monthly or quarterly basis and may include lockbox or control account arrangements. In general, the Bank receives and reviews 
financial statements and other documents of borrowing customers on an ongoing basis during the term of the relationship and responds to any 
deterioration noted.

Table of Contents 

        (3)    SBA Loans.    SBA loans are made through programs designed by the federal government to assist the small business community in 
obtaining financing from financial institutions that are given government guarantees as an incentive to make the loans. Our SBA loans fall into two 
categories, loans originated under the SBA's 7a Program ("7a Loans") and loans originated under the SBA's 504 Program ("504 Loans"). SBA 7a 
Loans are commercial business loans generally made for the purpose of purchasing real estate to be occupied by the business owner, providing 
working capital, and/or purchasing equipment, accounts receivable or inventory. SBA 504 Loans are collateralized by commercial real estate and 
are generally made to business owners for the purpose of purchasing or improving real estate for their use and for equipment used in their 
business.  

        SBA lending is subject to federal legislation that can affect the availability and funding of the program. From time to time, this dependence on 
legislative funding causes limitations and uncertainties with regard to the continued funding of such programs, which could potentially have an 
adverse financial impact on our business.  

        The Bank's portfolio of SBA loans is subject to certain risks, including, but not limited to: (i) the effects of economic downturns in the 
Southern California economy; (ii) interest rate increases; (iii) deterioration of the value of the underlying collateral; and (iv) deterioration of a 
borrower's or guarantor's financial capabilities. We strive to reduce the exposure of such risks through: (a) reviewing each loan request and 
renewal individually; (b) using a dual signature approval system; (c) adhering to written loan policies; (d) adhering to SBA written policies and 
regulations; (e) obtaining independent third party appraisals which are reviewed by the Bank's appraisal department; and (f) obtaining external 
independent credit reviews. In addition, SBA loans normally require monthly installment payments of principal and interest and therefore are 
continually monitored for past due conditions. In general, the Bank receives and reviews financial statements and other documents of borrowing 
customers on an ongoing basis during the term of the relationship and responds to any deterioration noted.  

        (4)    Consumer Loans.    Consumer loans include personal loans, auto loans, boat loans, home improvement loans, revolving lines of credit 
and other loans typically made by banks to individual borrowers. The Bank does not currently originate first trust deed home mortgage loans. The 
Bank's consumer loan portfolio is subject to certain risks, including: (i) amount of credit offered to consumers in the market; (ii) interest rate 
increases; and (iii) consumer bankruptcy laws which allow consumers to discharge certain debts. We strive to reduce the exposure to such risks 
through the direct approval of all consumer loans by: (a) reviewing each loan request and renewal individually; (b) using a dual signature approval 
system; (c) adhering to written credit policies; and (d) obtaining external independent credit reviews.  

        As part of our efforts to achieve long-term stable profitability and respond to a changing economic environment in Southern California and in 
other areas where we operate, we constantly evaluate a variety of options to augment our traditional focus by broadening the services and 
products we provide. Possible avenues of growth include more branch locations, expanded days and hours of operation and new types of loan 
and deposit products. To date, we have not expanded into areas of brokerage, annuity, insurance or similar investment products and services and 
have concentrated primarily on the core businesses of accepting deposits, making loans and extending credit.

        No individual or single group of related accounts is considered material in relation to our total assets or deposits of the Bank, or in relation to 
the overall business of the Company. However, approximately 79% of our total gross non-covered and covered loan portfolio at December 31, 2011 
consisted of real estate loans, including miniperm loans, SBA 504 loans, and construction loans. See "Item 7. Management's Discussion and 
Analysis of Financial Condition and Results of Operations—Financial Condition—Non-Covered Loans," and also "Item 7. Management's 
Discussion and Analysis of Financial Condition and Results of Operations—Financial Condition—Covered Loans." Since our business activities 
are currently focused primarily in Southern California, with the majority of our business concentrated in Los Angeles, Orange, Riverside, San 
Bernardino, San Diego, Ventura, Santa Barbara and San Luis Obispo Counties, our results of operations and financial condition are dependent 
upon the general trends in the Southern California economies and, in particular, the residential and commercial real estate markets. The 
concentration of our operations in Southern California exposes us to greater risk than other banking companies with a wider geographic base in the 
event of catastrophes, such as earthquakes, fires and floods in this region.  

        Our foreign loans consist predominately of commercial loans to individuals or entities located in Mexico and represent less than 1% of our 
non-covered loan portfolio at December 31, 2011. Such foreign loans are denominated in U.S. dollars and most are collateralized by assets located 
in the United States or are guaranteed or insured by businesses located in the United States. We have continued to allow our foreign loan portfolio 
to repay in the ordinary course of business without making any new privately-insured foreign loans other than those under existing commitments.

Strategic Evolution and Acquisition Strategy  

        The Company was organized on October 22, 1999 as a California corporation for the purpose of becoming a bank holding company and to 
acquire all the outstanding capital stock of Rancho Santa Fe National Bank. Since that time, we have grown through a series of business 
acquisitions.  

        The following chart summarizes the acquisitions completed since our inception, some of which are described in more detail below. See also 
Note 3, Acquisitions, of the Notes to Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data" for 
further details regarding recent acquisitions.

        Our acquisitions focused generally on increasing our banking presence in California and increasing earning assets. Our most recent 
acquisition of an interest-earning asset generation company added earning assets and deployed excess liquidity and the FDIC-assisted banking 
acquisitions expanded our operations and branch banking network in California.  

Marquette Equipment Finance Acquisition  

        On January 3, 2012, Pacific Western Bank completed the acquisition of Marquette Equipment Finance, or MEF, an equipment leasing company 
located in Midvale, Utah. Pacific Western Bank acquired all of the capital stock of MEF from Meridian Bank, N.A. for $35 million in cash. MEF 
focuses on business-essential equipment leases throughout the United States with transactions primarily in the mid-ticket segment. This 
acquisition diversifies our loan portfolio, expands our product line, and provides growth opportunities. It also importantly deployed our excess 
liquidity into higher-yielding assets.  

        At January 3, 2012, MEF had $162.2 million in gross leases and leases in process outstanding, with no leases on nonaccrual status. MEF's 
leases are spread across 18 industries, with the top three being  

9 

 
  
 
Table of Contents 

financial services/insurance, manufacturing, and health care and representing 68% of the lease portfolio balance. The weighted average yield on 
the lease portfolio at year end 2011 was approximately 9% and its weighted average remaining maturity was 34 months. In addition, Pacific Western 
Bank assumed $154.8 million in outstanding debt and other liabilities, which included $129 million payable to MEF's former parent. Pacific Western 
Bank repaid MEF's intercompany debt on the closing date from its excess liquidity on deposit at the Federal Reserve Bank. This resulted in MEF's 
interest-earning assets being funded with our low-cost deposit base.  

        Effective March 23, 2012, MEF will change its name to Pacific Western Equipment Finance and operate under this name as a division of Pacific 
Western Bank. Pacific Western Bank retained all 71 MEF employees.  

Los Padres Bank Acquisition  

        On August 20, 2010, we acquired certain assets of Los Padres Bank, including all loans, and assumed substantially all of its liabilities, 
including all deposits, from the FDIC in an FDIC-assisted acquisition, which we refer to as the Los Padres acquisition. Pacific Western (i) acquired 
$437.1 million in loans, $33.9 million in other real estate owned, $44.3 million in investments, and $261.5 million in cash and other assets and 
(ii) assumed $752.2 million in deposits, $70.0 million in borrowings, and $1.9 million in other liabilities. In connection with the Los Padres 
acquisition, the FDIC made a cash payment to Pacific Western of $144.0 million. Other than a deposit premium of $3.4 million, we paid no cash or 
other consideration to acquire Los Padres.  

        We entered into a loss sharing agreement with the FDIC, whereby the FDIC agreed to cover a substantial portion of any future losses on 
acquired loans, with the exception of consumer loans, and other real estate owned. Under the terms of such loss sharing agreement, the FDIC is 
obligated to reimburse the Bank for 80% of losses with respect to the covered assets. The Bank will reimburse the FDIC for 80% of recoveries with 
respect to losses for which the FDIC paid the Bank 80% reimbursement under the loss sharing agreement. The loss sharing provisions for single 
family covered assets and commercial (non-single family) covered assets are in effect for 10 years and 5 years, respectively, from the acquisition 
date, and the loss recovery provisions are in effect for 10 years and 8 years, respectively, from the acquisition date. We refer to the acquired assets 
subject to the loss sharing agreement collectively as "covered assets."  

        Los Padres was a federally chartered savings bank headquartered in Solvang, California that operated 14 branches, including 11 branches in 
California (three in Ventura County, four in Santa Barbara County, and four in San Luis Obispo County) and three branches in Arizona (Maricopa 
County). After office consolidations in 2011, we are operating eight of the former Los Padres branch offices, all of which are located in California. 
We made this acquisition to expand our presence in the Central Coast of California.  

Affinity Bank Acquisition  

        On August 28, 2009, we acquired substantially all of the assets of Affinity Bank, including all loans, and assumed substantially all of its 
liabilities, including the insured and uninsured deposits and excluding certain brokered deposits, from the FDIC in an FDIC-assisted transaction, 
which we refer to as the Affinity acquisition. Pacific Western (i) acquired $675.6 million in loans, $22.9 million in foreclosed assets, $175.4 million in 
investments and $371.5 million in cash and other assets, and (ii) assumed $868.2 million in deposits, $305.8 million in borrowings, and $32.6 million 
in other liabilities. In connection with the Affinity acquisition, the FDIC made a cash payment to Pacific Western of $87.2 million.  

        We entered into a loss sharing agreement with the FDIC, whereby the FDIC agreed to cover a substantial portion of any future losses on 
acquired loans, other real estate owned, or OREO, and  

10 

Table of Contents 

certain investment securities. Under the terms of such loss sharing agreement, the FDIC will absorb 80% of losses and receive 80% of loss 
recoveries on the first $234 million of losses on covered assets and absorb 95% of losses and receive 95% of loss recoveries on covered assets 
exceeding $234 million. The loss sharing provisions are in effect for 5 years for commercial assets (non-residential loans, OREO and certain 
securities) and 10 years for residential loans from the August 28, 2009 acquisition date. The loss recovery provisions are in effect for 8 years for 
commercial assets and 10 years for residential loans from the acquisition date. We refer to the acquired assets subject to the loss sharing 
agreement collectively as "covered assets." Affinity was a full service commercial bank headquartered in Ventura, California that operated 10 
branch locations in California, all of which we continue to operate. We made this acquisition to expand our presence in California.  

Competition  

        The banking business in California, and specifically in the Bank's primary service areas, is highly competitive with respect to originating loans, 
acquiring deposits and providing other banking services. The market is dominated by commercial banks in Southern California with assets between 
$500 million and $25 billion, including ourselves, and a few banking giants with a large number of offices and full-service operations over a wide 
geographic area. In recent years, competition has increased from institutions not subject to the same regulatory restrictions as domestic banks and 
bank holding companies. Those competitors include savings and loan associations, brokerage houses, insurance companies, mortgage companies, 
credit unions, credit card companies, and other financial and non-financial institutions and entities.  

        Economic factors, along with legislative and technological changes, will have an ongoing impact on the competitive environment within the 
financial services industry. We work to anticipate and adapt to dynamic competitive conditions whether it may be developing and marketing 
innovative products and services, adopting or developing new technologies that differentiate our products and services, cross marketing, or 
providing highly personalized banking services. We strive to distinguish ourselves from other community banks and financial services providers 
in our marketplace by providing an extremely high level of service to enhance customer loyalty and to attract and retain business. However, we can 
provide no assurance as to the effectiveness of these efforts on our future business or results of operations, as to our continued ability to 
anticipate and adapt to changing conditions, and as to sufficiently improving our services and/or banking products in order to successfully 
compete in our primary service areas.  

Employees  

        As of February 28, 2012, the Company had 982 full time equivalent employees.  

Financial and Statistical Disclosure  

        Certain of our statistical information is presented within "Item 6. Selected Financial Data," "Item 7. Management's Discussion and Analysis of 
Financial Condition and Results of Operations" and "Item 7A. Qualitative and Quantitative Disclosure About Market Risk." This information 
should be read in conjunction with the consolidated financial statements contained in "Item 8. Financial Statements and Supplementary Data."  

Supervision and Regulation  

General  

        The banking and financial services business in which we engage is highly regulated. Such regulation is intended, among other things, to 
protect the interests of customers, including depositors. These regulations are not, however, generally charged with protecting the interests of our 
shareholders or  

11 

 
 
 
 
Table of Contents 

creditors. Described below are the material elements of selected laws and regulations applicable to PacWest and its subsidiaries. The descriptions 
are not intended to be complete and are qualified in their entirety by reference to the full text of the statutes and regulations described. Changes in 
applicable law or regulations, and in their application by regulatory agencies, cannot be predicted, but they may have a material effect on the 
business and results of PacWest and its subsidiaries.  

        The commercial banking business is also influenced by the monetary and fiscal policies of the federal government and the policies of the 
Board of Governors of the Federal Reserve System, or FRB. The FRB implements national monetary policies (with the dual mandate of price 
stability and maximum employment) by its open-market operations in United States Government securities, by adjusting the required level of and 
paying interest on reserves for financial intermediaries subject to its reserve requirements and by varying the discount rates applicable to 
borrowings by depository institutions. The actions of the FRB in these areas influence the growth of bank loans, investments and deposits and 
also affect interest rates charged on loans and paid on deposits. Indirectly, such actions may also impact the ability of non-bank financial 
institutions to compete with the Bank. The nature and impact of any future changes in monetary policies cannot be predicted.  

        The events of the past few years have led to numerous new laws in the United States and internationally for financial institutions. The Dodd-
Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act" or "Dodd-Frank"), which was enacted in July 2010, significantly 
restructured the financial regulatory regime in the United States, including through the creation of a new systemic risk oversight body, the 
Financial Stability Oversight Council ("FSOC"). The FSOC oversees and coordinate the efforts of the primary U.S. financial regulatory agencies 
(including the FRB, the SEC, the Commodity Futures Trading Commission and the FDIC) in establishing regulations to address financial stability 
concerns. In addition to the framework for systemic risk oversight implemented through the FSOC, the Dodd-Frank Act broadly affected the 
financial services industry by creating a resolution authority, mandating higher capital and liquidity requirements, requiring banks to pay increased 
fees to regulatory agencies, and through numerous other provisions aimed at strengthening the sound operation of the financial services sector. 
As discussed further throughout this section, many aspects of Dodd-Frank continue to be subject to rulemaking and will take effect over several 
years, making it difficult to anticipate the overall financial impact on PacWest or across the industry.  

Bank Holding Company Regulation  

        As a bank holding company, PacWest is registered with and subject to regulation by the FRB under the Bank Holding Company Act of 1956, 
as amended, or the BHCA. FRB policy historically has required bank holding companies to act as a source of financial strength to their bank 
subsidiaries and to commit capital and financial resources to support those subsidiaries in circumstances where it might not otherwise do so. The 
Dodd-Frank Act codified this policy as a statutory requirement. Under this requirement, the Company is expected to commit resources to support 
the Bank, including at times when we may not be in a financial position to do so. Similarly, under the cross-guarantee provisions of the Federal 
Deposit Insurance Act, the FDIC can hold any FDIC-insured depository institution liable for any loss suffered or anticipated by the FDIC in 
connection with (i) the default of a commonly controlled FDIC-insured depository institution or (ii) any assistance provided by the FDIC to such a 
commonly controlled institution. Under the BHCA, we are subject to periodic examination by the FRB. We are also required to file with the FRB 
periodic reports of our operations and such additional information regarding the Company and its subsidiaries as the FRB may require. Pursuant to 
the BHCA, we are required to obtain the prior approval of the FRB before we acquire all or substantially all of the assets of any bank or ownership 
or control of voting shares of any bank if, after giving effect to such acquisition, we would own or control, directly or indirectly, more than 
5 percent of such bank.  

12 

Table of Contents 

        Under the BHCA, we may not engage in any business other than managing or controlling banks or furnishing services to our subsidiaries that 
the FRB deems to be so closely related to banking as "to be a proper incident thereto." We are also prohibited, with certain exceptions, from 
acquiring direct or indirect ownership or control of more than 5 percent of the voting shares of any company unless the company is engaged in 
banking activities or the FRB determines that the activity is so closely related to banking as to be a proper incident to banking. The FRB's approval 
must be obtained before the shares of any such company can be acquired and, in certain cases, before any approved company can open new 
offices.  

        The BHCA and regulations of the FRB also impose certain constraints on the redemption or purchase by a bank holding company of its own 
shares of stock.  

        Additionally, bank holding companies that meet certain eligibility requirements prescribed by the BHCA and elect to operate as financial 
holding companies may engage in, or own shares in companies engaged in, a wider range of nonbanking activities, including securities and 
insurance activities and any other activity that the FRB, in consultation with the Secretary of the Treasury, determines by regulation or order is 
financial in nature, incidental to any such financial activity or complementary to any such financial activity and does not pose a substantial risk to 
the safety or soundness of depository institutions or the financial system generally. As of the date of this filing, we do not operate as a financial 
holding company.  

        Our earnings and activities are affected by legislation, by regulations and by local legislative and administrative bodies and decisions of 
courts in the jurisdictions in which we and the Bank conduct business. For example, these include limitations on the ability of the Bank to pay 
dividends to us and our ability to pay dividends to our shareholders. It is the policy of the FRB that bank holding companies should pay cash 
dividends on common stock only out of income available over the past year and only if prospective earnings retention is consistent with the 
organization's expected future needs and financial condition. The policy provides that bank holding companies should not maintain a level of cash 
dividends that undermines the bank holding company's ability to serve as a source of strength to its banking subsidiaries. Various federal and 
state statutory provisions limit the amount of dividends that subsidiary banks and savings associations can pay to their holding companies 
without regulatory approval.  

        In addition to these explicit limitations, the federal regulatory agencies have general authority to prohibit a banking subsidiary or bank holding 
company from engaging in an unsafe or unsound banking practice. Depending upon the circumstances, the agencies could take the position that 
paying a dividend would constitute an unsafe or unsound banking practice. Further, as discussed below under "—Regulation of the Bank", a bank 
holding company such as the Company is required to maintain minimum ratios of Tier 1 capital and total capital to total risk-weighted assets, and a 
minimum ratio of Tier 1 capital to total adjusted quarterly average assets as defined in such regulations. The level of our capital ratios may affect 
our ability to pay dividends. See "Item 5. Market for Registrant's Common Equity and Related Stockholder Matters—Dividends" and Note 19, 
Dividend Availability and Regulatory Matters, of the Notes to Consolidated Financial Statements contained in "Item 8. Financial Statements and 
Supplementary Data."  

        Banking subsidiaries of bank holding companies are also subject to certain restrictions imposed by federal law in dealings with their holding 
companies and other affiliates. Subject to certain exceptions set forth in the Federal Reserve Act, a bank can make a loan or extend credit to an 
affiliate, purchase or invest in the securities of an affiliate, purchase assets from an affiliate, accept securities of an affiliate as collateral for a loan or 
extension of credit to any person or company, issue a guarantee or accept letters of credit on behalf of an affiliate only if the aggregate amount of 
the above transactions of such subsidiary does not exceed 10 percent of such subsidiary's capital stock and surplus on an individual basis or 
20 percent of such subsidiary's capital stock and surplus on an aggregate basis. Such  

13 

Table of Contents 

transactions must be on terms and conditions that are consistent with safe and sound banking practices. A bank holding company and its 
subsidiaries generally may not purchase a "low-quality asset," as that term is defined in the Federal Reserve Act, from an affiliate. Such restrictions 
also prevent a holding company and its other affiliates from borrowing from a banking subsidiary of the holding company unless the loans are 
secured by collateral. The Dodd-Frank Act significantly expands the coverage and scope of the limitations on affiliate transactions within a 
banking organization.  

        The FRB has cease and desist powers over parent bank holding companies and non-banking subsidiaries where the action of a parent bank 
holding company or its non-financial institutions represent an unsafe or unsound practice or violation of law. The FRB has the authority to 
regulate debt obligations, other than commercial paper, issued by bank holding companies by imposing interest ceilings and reserve requirements 
on such debt obligations.  

        The Dodd-Frank Act requires the federal financial regulatory agencies to adopt rules that prohibit banks and their affiliates from engaging in 
proprietary trading and investing in and sponsoring certain unregistered investment companies (defined as hedge funds and private equity funds), 
with implementation starting as early as July 2012. The statutory provision is commonly called the "Volcker Rule". In October 2011, federal 
regulators proposed rules to implement the Volcker Rule which were issued for public comment, with comments due by February 13, 2012. The 
proposed rules are highly complex, and many aspects of their application remain uncertain. Based on the proposed rules, we do not currently 
anticipate that the Volcker Rule will have a material effect on our operations since we do not engage in the businesses prohibited by the Volcker 
Rule. We may incur costs if we are required to adopt additional policies and systems to ensure compliance with the Volcker Rule, but any such 
costs are not expected to be material. Until a final rule is adopted, the precise financial impact of the rule on the Company, its customers or the 
financial industry more generally, cannot be determined.  

Regulation of the Bank  

        The Bank is extensively regulated under both federal and state law. Various requirements and restrictions under federal and state law affect the 
operations of the Bank. Federal and state statutes and regulations relate to many aspects of the Bank's operations, including standards for safety 
and soundness, reserves against deposits, interest payable on certain deposit products, investments, mergers and acquisitions, borrowings, 
dividends, locations of branch offices, fair lending requirements, Community Reinvestment Act activities and loans to affiliates.  

        The Dodd-Frank Act applies the same leverage and risk-based capital requirements that apply to insured depository institutions to bank 
holding companies, such as the Company. The guidelines of the FRB and FDIC are intended to ensure that banking organizations have adequate 
capital given the risk levels of assets and off-balance sheet financial instruments. Under the guidelines, banking organizations are required to 
maintain minimum ratios for Tier 1 capital and total capital to risk-weighted assets (including certain off-balance sheet items, such as letters of 
credit). For purposes of calculating the ratios, a banking organization's assets and some of its specified off-balance sheet commitments and 
obligations are assigned to various risk categories. A depository institution's or holding company's capital, in turn, is classified in one of three 
tiers, depending on type:  

• 

• 

Core Capital (Tier 1).  Tier 1 capital includes common equity, retained earnings, qualifying non-cumulative perpetual preferred 
stock, a limited amount of qualifying cumulative perpetual stock at the holding company level, minority interests in equity accounts 
of consolidated subsidiaries, and qualifying trust preferred securities less goodwill, most intangible assets and certain other assets.  

Supplementary Capital (Tier 2).  Tier 2 capital includes, among other things, perpetual preferred stock and trust preferred 
securities not meeting the Tier 1 definition, qualifying mandatory  

14 

 
Table of Contents 

convertible debt securities, qualifying subordinated debt, and allowances for possible credit losses, subject to limitations.

Market Risk Capital (Tier 3).  Tier 3 capital includes qualifying unsecured subordinated debt.  

        Regulatory capital requirements limit the amount of deferred tax assets that may be included when determining the amount of regulatory 
capital. Deferred tax asset amounts in excess of the calculated limit are deducted from regulatory capital. See "Item 7. Management's Discussion 
and Analysis of Financial Condition and Results of Operations—Capital Resources" for further information on regulatory capital requirements and 
ratios as of December 31, 2011 for Pacific Western and the Company.  

        The Company issued subordinated debentures to trusts that were established by us or entities we have acquired, which, in turn, issued trust 
preferred securities, which totaled $123.0 million at December 31, 2011. The Company includes in Tier 1 capital an amount of trust preferred 
securities equal to no more than 25% of the sum of all core capital elements, which is generally defined as shareholders' equity less goodwill, net of 
any related deferred income tax liability. While our existing trust preferred securities are grandfathered under the Dodd-Frank Wall Street Reform 
and Consumer Protection Act that was enacted in July 2010, new issuances will not qualify as Tier 1 capital. See "Item 7. Management's Discussion 
and Analysis of Financial Condition and Results of Operations—Borrowings" for information regarding the redemption in March 2012 of certain of 
our subordinated debentures.  

        The FDIC and FRB risk-based capital guidelines are based upon the 1988 Capital Accord ("Basel I") of the Basel Committee on Banking 
Supervision (the "Basel Committee"). The Basel Committee is a committee of central banks and bank supervisors/regulators from the major 
industrialized countries that develops broad policy guidelines that each country's supervisors can use to determine the supervisory policies they 
apply. After working on revisions for a number of years, in June 2004, the Basel Committee released the final version of a proposed new capital 
framework, with an update in November 2005 ("Basel II). Basel II proposes two approaches for setting capital standards for credit risk—an internal 
ratings-based approach tailored to individual institutions' circumstances (which for many asset classes is itself broken into a "foundation" 
approach and an "advanced" or "A-IRB" approach, the availability of which is subject to additional restrictions) and a standardized approach that 
bases risk weightings on external credit assessments to a much greater extent than permitted in existing risk-based capital guidelines. Basel II also 
would set capital requirements for operational risk and refine the existing capital requirements for market risk exposures.  

        In December 2006, the agencies issued a notice of proposed rulemaking setting forth a definitive proposal for implementing Basel II in the 
United States that would apply only to internationally active banking organizations—defined as those with consolidated total assets of 
$250 billion or more or consolidated on-balance sheet foreign exposures of $10 billion or more—but that other U.S. banking organizations could 
elect but would not be required to apply. In November 2007, the agencies adopted a definitive final rule for implementing Basel II in the United 
States that would apply only to internationally active banking organizations, or "core banks"—defined as those with consolidated total assets of 
$250 billion or more or consolidated on-balance sheet foreign exposures of $10 billion or more. The final rule was effective on April 1, 2008.  

        The Company is not required to comply with Basel II and we have not adopted the Basel II approach.  

        In June 2008, the U.S. banking and thrift agencies announced a proposed rule that would provide all non-core banking organizations (that is, 
banking organizations not required to adopt the advanced approaches) with the option to adopt a way to determine required regulatory capital that 
is more risk sensitive than the current Basel I-based rules, yet is less complex than the advanced approaches in the  

15

final rule. The proposed standardized framework addresses (i) expanding the number of risk-weight categories to which credit exposures may be 
assigned; (ii) using loan-to-value ratios to risk weight most residential mortgages to enhance the risk sensitivity of the capital requirement; 
(iii) providing a capital charge for operational risk using the Basic Indicator Approach under the international Basel II capital accord; 
(iv) emphasizing the importance of a bank's assessment of its overall risk profile and capital adequacy; and (v) providing for comprehensive 
disclosure requirements to complement the minimum capital requirements and supervisory process through market discipline. This new proposal 
will replace the agencies' earlier Basel I-A proposal, issued in December 2006.  

        In December 2010, the Basel Committee released its final framework for strengthening international capital and liquidity regulation, now 
officially identified by the Basel Committee as "Basel III". Basel III, when implemented by the U.S. banking agencies and fully phased-in, will 
require bank holding companies and their bank subsidiaries to maintain substantially more capital, with a greater emphasis on common equity.  

        The Basel III final capital framework, among other things: 

• 

• 

• 

introduces as a new capital measure "Common Equity Tier 1", or "CET1", specifies that Tier 1 capital consists of CET1 and 
"Additional Tier 1 capital" instruments meeting specified requirements, defines CET1 narrowly by requiring that most adjustments 
to regulatory capital measures be made to CET1 and not to the other components of capital, and expands the scope of the 
adjustments as compared to existing regulations;  

when fully phased in on January 1, 2019, requires banks to maintain:  

• 

• 

• 

• 

as a newly adopted international standard, a minimum ratio of CET1 to risk-weighted assets of at least 4.5%, plus a 2.5% 
"capital conservation buffer" (which is added to the 4.5% CET1 ratio as that buffer is phased in, effectively resulting in a 
minimum ratio of CET1 to risk-weighted assets of at least 7%);  

a minimum ratio of Tier 1 capital to risk-weighted assets of at least 6.0%, plus the capital conservation buffer (which is added 
to the 6.0% Tier 1 capital ratio as that buffer is phased in, effectively resulting in a minimum Tier 1 capital ratio of 8.5% upon 
full implementation);  

a minimum ratio of Total (that is, Tier 1 plus Tier 2) capital to risk-weighted assets of at least 8.0%, plus the capital 
conservation buffer (which is added to the 8.0% total capital ratio as that buffer is phased in, effectively resulting in a 
minimum total capital ratio of 10.5% upon full implementation); and  

as a newly adopted international standard, a minimum leverage ratio of 3%, calculated as the ratio of Tier 1 capital to balance 
sheet exposures plus certain off-balance sheet exposures (as the average for each quarter of the month-end ratios for the 
quarter); and  

provides for a "countercyclical capital buffer", generally to be imposed when national regulators determine that excess aggregate 
credit growth becomes associated with a buildup of systemic risk, that would be a CET1 add-on to the capital conservation buffer in 
the range of 0% to 2.5% when fully implemented (potentially resulting in total buffers of between 2.5% and 5%).  

        The capital conservation buffer is designed to absorb losses during periods of economic stress. Banking institutions with a ratio of CET1 to 
risk-weighted assets above the minimum but below the conservation buffer (or below the combined capital conservation buffer and countercyclical 
capital buffer, when the latter is applied) will face constraints on dividends, equity repurchases and compensation based on the amount of the 
short fall.  

16 

 
 
 
 
 
 
Table of Contents 

        The implementation of the Basel III final framework will commence January 1, 2013. On that date, banking institutions will be required to meet 
the following minimum capital ratios: 

• 

• 

• 

3.5% CET1 to risk-weighted assets;  

4.5% Tier 1 capital to risk-weighted assets; and  

8.0% Total capital to risk-weighted assets.  

        The Basel III final framework provides for a number of new deductions from and adjustments to CET1. These include, for example, the 
requirement that mortgage servicing rights, deferred tax assets dependent upon future taxable income and significant investments in non-
consolidated financial entities be deducted from CET1 to the extent that any one such category exceeds 10% of CET1 or all such categories in the 
aggregate exceed 15% of CET1.  

        Implementation of the deductions and other adjustments to CET1 will begin on January 1, 2014 and will be phased-in over a five-year period 
(20% per year). The implementation of the capital conservation buffer will begin on January 1, 2016 at 0.625% and be phased in over a four-year 
period (increasing by that amount on each subsequent January 1, until it reaches 2.5% on January 1, 2019).  

        The U.S. banking agencies are expected to publish notice of proposed rule-making with respect to at least certain portions of Basel III during 
the first half of 2012. Given that the Basel III rules are subject to change, and the scope and content of capital regulations that the U.S. banking 
agencies may adopt under Dodd-Frank is uncertain, we cannot be certain of the impact new capital regulations will have on our capital ratios.  

        Historically, regulation and monitoring of bank and bank holding company liquidity has been addressed as a supervisory matter, both in the 
U.S. and internationally, without required formulaic measures. The Basel III final framework requires banks and bank holding companies to measure 
their liquidity against specific liquidity tests that, although similar in some respects to liquidity measures historically applied by banks and 
regulators for management and supervisory purposes, going forward will be required by regulation. One test, referred to as the liquidity coverage 
ratio ("LCR"), is designed to ensure that the banking entity maintains an adequate level of unencumbered high-quality liquid assets equal to the 
entity's expected net cash outflow for a 30-day time horizon (or, if greater, 25% of its expected total cash outflow) under an acute liquidity stress 
scenario. The other, referred to as the net stable funding ratio ("NSFR"), is designed to promote more medium- and long-term funding of the assets 
and activities of banking entities over a one-year time horizon. These requirements will incent banking entities to increase their holdings of U.S. 
Treasury securities and other sovereign debt as a component of assets and increase the use of long-term debt as a funding source. The LCR would 
be implemented subject to an observation period beginning in 2011, but would not be introduced as a requirement until January 1, 2015, and the 
NSFR would not be introduced as a requirement until January 1, 2018. These new standards are subject to further rulemaking and their terms may 
well change before implementation.  

Prompt Corrective Action  

        The Federal Deposit Insurance Corporation Improvement Act, or FDICIA, requires each federal banking agency to take prompt corrective 
action to resolve the problems of insured depository institutions, including but not limited to those that fall below one or more prescribed minimum 
capital ratios. Pursuant to FDICIA, the FDIC promulgated regulations defining the following five categories in which an insured depository 
institution will be placed, based on the level of its capital ratios: well capitalized, adequately capitalized, undercapitalized, significantly 
undercapitalized and critically undercapitalized. Under the prompt corrective action provisions of FDICIA, an insured depository institution 
generally will be classified as undercapitalized if its total risk-based capital is less than 8% or its Tier 1 risk-based capital or leverage ratio is less 
than 4%. An institution that, based upon its capital  

17 

 
 
Table of Contents 

levels, is classified as "well capitalized", "adequately capitalized" or "undercapitalized" may be treated as though it were in the next lower capital 
category if the appropriate federal banking agency, after notice and opportunity for hearing, determines that an unsafe or unsound condition or an 
unsafe or unsound practice warrants such treatment. At each successive lower capital category, an insured depository institution is subject to 
more restrictions and prohibitions, including restrictions on growth, restrictions on interest rates paid on deposits, prohibitions on payment of 
dividends and restrictions on the acceptance of brokered deposits. Furthermore, if a bank is classified in one of the undercapitalized categories, it 
is required to submit a capital restoration plan to the federal bank regulator, and the holding company must guarantee the performance of that plan.  

        In addition to measures taken under the prompt corrective action provisions, commercial banking organizations may be subject to potential 
enforcement actions by the federal or state banking agencies for unsafe or unsound practices in conducting their businesses or for violations of 
any law, rule, regulation or any condition imposed in writing by the agency or any written agreement with the agency. Enforcement actions may 
include the imposition of a conservator or receiver, the issuance of a cease-and-desist order that can be judicially enforced, the termination of 
insurance for deposits (in the case of a depository institution), the imposition of civil money penalties, the issuance of directives to increase 
capital, the issuance of formal and informal agreements, the issuance of removal and prohibition orders against institution- affiliated parties. The 
enforcement of such actions through injunctions or restraining orders may be based upon a judicial determination that the agency would be 
harmed if such equitable relief was not granted.  

Deposit Insurance  

        Pacific Western is a state-chartered, "non-member" bank and therefore is regulated by the California Department of Financial Institutions, or 
DFI, and the FDIC. Pacific Western is also an FDIC insured financial institution whereby the FDIC provides deposit insurance for a certain 
maximum dollar amount per customer.  

        The Bank, as is the case with all FDIC insured banks, is subject to deposit insurance assessments as determined by the FDIC. Historically, the 
FDIC imposed insurance premiums based on the amount of deposits held and a risk matrix took into account, among other factors, a bank's capital 
level and supervisory rating. Pursuant to the Dodd-Frank Act, the FDIC amended its regulations to determine insurance assessments based on the 
average consolidated assets less the average tangible equity of the insured depository institution during the assessment period. Based on the 
current FDIC insurance assessment methodology our FDIC insurance assessment was $5.6 million for 2011 and is estimated to be $4.3 million for 
2012. In addition, the Dodd-Frank Act requires the FDIC to adopt a new Deposit Insurance Fund restoration plan to ensure that the fund reserve 
ratio reaches 1.35% by September 30, 2020. At least semi-annually, the FDIC will update its loss and income projections for the fund and, if needed, 
will increase or decrease assessment rates, following notice-and-comment rulemaking if required.  

        The changes to the FDIC insurance assessment calculation and fund requirements are a result of the liquidity concerns that arose during the 
market disruption in 2008. In late 2008, in an effort to strengthen confidence and encourage liquidity in the banking system, the FDIC temporarily 
increased the maximum amount of deposit insurance to $250,000 per customer and adopted a number of programs, including the Transaction 
Account Guarantee Program. The Transaction Account Guarantee Program guaranteed the entire balance of non-interest bearing deposit 
transaction accounts through December 31, 2010. Institutions participating in the Transaction Account Guarantee Program were charged a 10-basis 
point fee on the balance of non-interest bearing deposit transaction accounts exceeding the existing deposit insurance limit of $250,000. The cost 
to the Bank for participating in this program was $794,000 for 2010 and $452,000 for 2009. Under Dodd-Frank, the $250,000 maximum amount was 
made permanent, and the unlimited protection for noninterest-bearing transaction accounts  

18 

Table of Contents 

was extended to December 31, 2012 and to all insured depository institutions without a separate surcharge.  

        In the second quarter of 2009, the FDIC imposed a special assessment on all depository institutions; such assessment was $2.0 million for the 
Bank. In addition, the FDIC required insured depository institutions to prepay their estimated quarterly assessments for the fourth quarter of 2009, 
and for all of 2010, 2011, and 2012. The amount of Pacific Western's FDIC assessment prepayment was $19.5 million, which we paid on 
December 30, 2009.  

        The 2009 prepayments and special assessment for FDIC insurance are in contrast to the lower FDIC insurance assessment expense for Pacific 
Western in 2008 and 2007. Because of favorable loss experience and a healthy reserve ratio in the deposit insurance fund of the FDIC, well-
capitalized and well-managed banks, including Pacific Western, paid minimal premiums for FDIC insurance during 2008 and 2007. A deposit 
premium refund, in the form of credit offsets, was given to banks that were in existence on December 31, 1996 and paid deposit insurance premiums 
prior to that date. Pacific Western utilized its credit offset to eliminate a portion of its 2008 and nearly all of its 2007 FDIC insurance assessments.  

Incentive Compensation  

        The Dodd-Frank Act requires the Federal bank regulatory agencies and the Securities and Exchange Commission to establish joint regulations 
or guidelines prohibiting incentive-based payment arrangements at specified regulated entities, such as the Company and the Bank, having at least 
$1 billion in total assets that encourage inappropriate risks by providing an executive officer, employee, director or principal shareholder with 
excessive compensation, fees, or benefits or that could lead to material financial loss to the entity. In addition, these regulators must establish 
regulations or guidelines requiring enhanced disclosure to regulators of incentive-based compensation arrangements. The agencies proposed 
such regulations in April 2011, which may become effective before the end of 2012. If the regulations are adopted in the form initially proposed, 
they will impose limitations on the manner in which we may structure compensation for our executives.  

        In June 2010, the FRB and the FDIC issued comprehensive final guidance on incentive compensation policies intended to ensure that the 
incentive compensation policies of banking organizations do not undermine the safety and soundness of such organizations by encouraging 
excessive risk-taking. The guidance, which covers all employees that have the ability to materially affect the risk profile of an organization, either 
individually or as part of a group, is based upon the key principles that a banking organization's incentive compensation arrangements should 
(i) provide incentives that do not encourage risk-taking beyond the organization's ability to effectively identify and manage risks, (ii) be compatible 
with effective internal controls and risk management, and (iii) be supported by strong corporate governance, including active and effective 
oversight by the organization's board of directors. These three principles are incorporated into the proposed joint compensation regulations under 
Dodd-Frank, discussed above. The FRB will review, as part of its regular, risk-focused examination process, the incentive compensation 
arrangements of banking organizations, such as the Company, that are not "large, complex banking organizations." These reviews will be tailored 
to each organization based on the scope and complexity of the organization's activities and the prevalence of incentive compensation 
arrangements. The findings of the supervisory initiatives will be included in reports of examination. Deficiencies will be incorporated into the 
organization's supervisory ratings, which can affect the organization's ability to make acquisitions and take other actions. Enforcement actions may 
be taken against a banking organization if its incentive compensation arrangements, or related risk-management control or governance processes, 
pose a risk to the organization's safety and soundness and the organization is not taking prompt and effective measures to correct the deficiency.

Consumer Regulation  

        The Dodd-Frank Act established the new Consumer Financial Protection Bureau (the "CFPB") with broad powers to supervise and enforce 
consumer protection laws. The CFPB has broad rule-making authority for a wide range of consumer protection laws that apply to all banks and 
savings institutions, including the authority to prohibit "unfair, deceptive or abusive" acts and practices. While CFPB's examination and 
enforcement authority only extends to banking organizations with more than $10 billion in assets, banks with less than $10 billion in assets, such 
as the Bank, will be examined for compliance with the CFPB's rules and regulations by their primary federal banking agency. Given the recent 
establishment of the CFPB, there is still uncertainty surrounding the expected impact of this bureau on us and other banks. The Dodd-Frank Act 
also weakens the federal preemption rules that have been applicable for national banks and gives state attorneys general the ability to enforce 
federal consumer protection laws.  

Depositor Preference  

        The Federal Deposit Insurance Act provides that, in the event of the "liquidation or other resolution" of an insured depository institution, the 
claims of depositors of the institution, including the claims of the FDIC as subrogee of insured depositors, and certain claims for administrative 
expenses of the FDIC as a receiver, will have priority over other general unsecured claims against the institution. If an insured depository 
institution fails, insured and uninsured depositors, along with the FDIC, will have priority in payment ahead of unsecured, non-deposit creditors, 
including the parent bank holding company, with respect to any extensions of credit they have made to such insured depository institution.  

Sarbanes-Oxley Act  

        As a publicly traded company, we are subject to the Sarbanes-Oxley Act of 2002 ("Sarbanes-Oxley Act"). The principal provisions of the 
Sarbanes-Oxley Act, many of which have been implemented or interpreted through regulations, provide for and include, among other things: (i) the 
creation of an independent accounting oversight board; (ii) auditor independence provisions that restrict non-audit services that accountants may 
provide to their audit clients; (iii) additional corporate governance and responsibility measures, including the requirement that the chief executive 
officer and chief financial officer of a public company certify financial statements; (iv) the forfeiture of bonuses or other incentive-based 
compensation and profits from the sale of an issuer's securities by directors and senior officers in the twelve month period following initial 
publication of any financial statements that later require restatement; (v) an increase in the oversight of, and enhancement of certain requirements 
relating to, audit committees of public companies and how they interact with the Company's independent auditors; (vi) requirements that audit 
committee members must be independent and are barred from accepting consulting, advisory or other compensatory fees from the issuer; 
(vii) requirements that companies disclose whether at least one member of the audit committee is a "financial expert" (as such term is defined by the 
SEC) and if not discussed, why the audit committee does not have a financial expert; (viii) expanded disclosure requirements for corporate insiders, 
including accelerated reporting of stock transactions by insiders and a prohibition on insider trading during pension blackout periods; (ix) a 
prohibition on personal loans to directors and officers, except certain loans made by insured financial institutions on nonpreferential terms and in 
compliance with other bank regulatory requirements; (x) disclosure of a code of ethics and filing a Form 8-K for a change or waiver of such code; 
(xi) a range of enhanced penalties for fraud and other violations; and (xii) expanded disclosure and certification relating to an issuer's disclosure 
controls and procedures and internal controls over financial reporting.  

        As a result of the Sarbanes-Oxley Act, and its implementing regulations, we have incurred substantial costs to interpret and ensure ongoing 
compliance with the law and its regulations. Future  

20 

Table of Contents 

changes in the laws, regulation, or policies that impact us cannot necessarily be predicted and may have a material effect on our business and 
earnings.  

USA PATRIOT Act  

        The Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001, or the 
PATRIOT Act, designed to deny terrorists and others the ability to obtain access to the United States financial system, has significant 
implications for depository institutions, brokers, dealers and other businesses involved in the transfer of money. The PATRIOT Act, as 
implemented by various federal regulatory agencies, requires financial institutions, including the Company, to establish and implement policies and 
procedures with respect to, among other matters, anti-money laundering, compliance, suspicious activity and currency transaction reporting and 
due diligence on customers. The PATRIOT Act and its underlying regulations permit information sharing for counter-terrorist purposes between 
federal law enforcement agencies and financial institutions, as well as among financial institutions, subject to certain conditions, and require the 
FRB, the FDIC and other federal banking agencies to evaluate the effectiveness of an applicant in combating money laundering activities when 
considering applications filed under Section 3 of the BHCA or the Bank Merger Act.  

        We regularly evaluate and continue to augment our systems and procedures to continue to comply with the PATRIOT Act and other anti-
money laundering initiatives. We believe that the ongoing cost of compliance with the PATRIOT Act is not likely to be material to the Company. 
Failure of a financial institution to maintain and implement adequate programs to combat money laundering and terrorist financing, or to comply 
with all of the relevant laws or regulations, could have serious legal and reputational consequences for the institution.  

Office of Foreign Assets Control Regulation  

        The United States has imposed economic sanctions that affect transactions with designated foreign countries, nationals and others. These are 
typically known as the "OFAC" rules based on their administration by the U.S. Treasury Department Office of Foreign Assets Control ("OFAC"). 
The OFAC-administered sanctions targeting countries take many different forms. Generally, however, they contain one or more of the following 
elements: (i) restrictions on trade with or investment in a sanctioned country, including prohibitions against direct or indirect imports from and 
exports to a sanctioned country and prohibitions on "U.S. persons" engaging in financial transactions relating to making investments in, or 
providing investment-related advice or assistance to, a sanctioned country; and (ii) a blocking of assets in which the government or specially 
designated nationals of the sanctioned country have an interest, by prohibiting transfers of property subject to U.S. jurisdiction (including 
property in the possession or control of U.S. persons). Blocked assets (e.g., property and bank deposits) cannot be paid out, withdrawn, set off or 
transferred in any manner without a license from OFAC. Failure to comply with these sanctions could have serious legal and reputational 
consequences.  

Community Reinvestment Act  

        The Community Reinvestment Act of 1977, or the CRA, generally requires insured depository institutions to identify the communities they 
serve and to make loans and investments, offer products, and provide services designed to meet the credit needs of these communities. The CRA 
also requires banks to maintain comprehensive records of its CRA activities to demonstrate how it is meeting the credit needs of their communities; 
these documents are subject to periodic examination by the FDIC. During these examinations, the FDIC rates such institutions' compliance with 
CRA as "Outstanding," "Satisfactory," "Needs to Improve" or "Substantial Noncompliance." The CRA requires the FDIC to take into account the 
record of a bank in meeting the credit needs of the entire communities served, including low-and moderate income neighborhoods, in determining 
such rating. Failure of an institution  

21 

Table of Contents 

to receive at least a "Satisfactory" rating could inhibit such institution or its holding company from undertaking certain activities, including 
acquisitions. The Bank received a CRA rating of "Satisfactory" as of its most recent examination.  

Customer Information Security  

        The FRB and other bank regulatory agencies have adopted final guidelines for safeguarding confidential, personal customer information. 
These guidelines require each financial institution, under the supervision and ongoing oversight of its board of directors or an appropriate 
committee thereof, to create, implement and maintain a comprehensive written information security program designed to ensure the security and 
confidentiality of customer information, protect against any anticipated threats or hazard to the security or integrity of such information and 
protect against unauthorized access to or use of such information that could result in substantial harm or inconvenience to any customer. We have 
adopted a customer information security program to comply with such requirements.  

Privacy  

        The Gramm-Leach-Bliley Act of 1999 and the California Financial Information Privacy Act require financial institutions to implement policies 
and procedures regarding the disclosure of nonpublic personal information about consumers to non-affiliated third parties. In general, the statutes 
require explanations to consumers on policies and procedures regarding the disclosure of such nonpublic personal information, and, except as 
otherwise required by law, prohibit disclosing such information except as provided in the Bank's policies and procedures. Pacific Western has 
implemented privacy policies addressing these restrictions which are distributed regularly to all existing and new customers of the Bank.  

Legislative and Regulatory Initiatives  

        From time to time, various legislative and regulatory initiatives are introduced in the U.S. Congress and state legislatures, as well as by 
regulatory agencies. Such initiatives may include proposals to expand or contract the powers of bank holding companies and depository 
institutions or proposals to substantially change the financial institution regulatory system. Such legislation could change banking statutes and 
our operating environment in substantial and unpredictable ways. If enacted, such legislation could increase or decrease the cost of doing 
business, limit or expand permissible activities or affect the competitive balance among banks, savings associations, credit unions, and other 
financial institutions. We cannot predict whether any such legislation will be enacted, and, if enacted, the effect that it, or any implementing 
regulations, would have on our financial condition, results of operations or cash flows. A change in statutes, regulations or regulatory policies 
applicable to the Company or any of its subsidiaries could have a material effect on our business.  

Hazardous Waste Clean-Up and Climate-Related Risk  

        Our primary exposure to environmental laws is through our lending activities and through properties or businesses we may own, lease or 
acquire since we are not involved in any business that manufactures, uses or transports chemicals, waste, pollutants or toxins that might have a 
material adverse effect on the environment. Based on a general survey of the Bank's loan portfolio, conversations with local appraisers and the 
type of lending currently and historically done by the Bank, we are not aware of any potential liability for hazardous waste contamination that 
would be reasonably likely to have a material adverse effect on the Company as of February 29, 2012. In addition, we are not aware of any physical 
or regulatory consequence resulting from climate change that would have a material adverse effect upon the Company.

ITEM 1A.    RISK FACTORS  

        Ownership of our common stock involves risk. You should carefully consider, in addition to the other information set forth herein, the 
following risk factors.  

Our business has been and may continue to be adversely affected by current conditions in the financial markets and economic conditions 
generally.  

        From December 2007 through June 2009, the U.S. economy was in recession and economic recovery through 2011 has been sluggish. As a 
result, the global financial markets have undergone and may continue to experience pervasive and fundamental disruptions. In some cases, the 
markets have produced downward pressure on stock prices and credit availability for certain issuers without regard to those issuers' underlying 
financial strength. While economic conditions have recently shown signs of improvement, the sustainability of an economic recovery is uncertain 
as business activity across a wide range of industries continues to face difficulties due to the lack of consumer spending and sustained high levels 
of unemployment.  

24 

 
 
 
 
 
 
 
 
 
 
 
Table of Contents 

        A sustained weakness or further weakening in business and economic conditions generally or specifically in the principal markets in which we 
do business could have one or more of the following adverse effects on our business: 

• 

• 

• 

• 

• 

• 

a decrease in the demand for loans and other products and services offered by us;  

a decrease in deposit balances due to overall reductions in the accounts of customers;  

a decrease in the value of our loans or other assets secured by consumer or commercial real estate;  

a decrease in net interest income derived from our lending and deposit gathering activities;  

an impairment of certain intangible assets; or  

an increase in the number of borrowers who become delinquent, file for protection under bankruptcy laws or default on their loans 
or other obligations to us. An increase in the number of delinquencies, bankruptcies or defaults could result in a higher level of 
nonperforming assets, net charge-offs and provision for credit losses.  

        Overall, the economic downturn has had an adverse effect on our business, and there can be no assurance that an economic recovery will be 
sustainable in the near term. Until conditions improve, we expect our business, financial condition and results of operations to be adversely 
affected.  

Changes in economic conditions, in particular a worsening of the economic slowdown in Southern California, could materially and adversely 
affect our business.  

        Our business is directly impacted by factors such as economic, political and market conditions, broad trends in industry and finance, 
legislative and regulatory changes, and changes in government monetary and fiscal policies and inflation, all of which are beyond our control. The 
current economic conditions have caused a lack of consumer confidence, increased market volatility and widespread reduction of business activity 
generally. These circumstances may lead to an increase in nonaccrual and classified loans, which generally results in a provision for credit losses 
and in turn reduces the Company's net earnings. The State of California continues to face fiscal challenges, the long-term effects of which on the 
State's economy cannot be predicted. A further deterioration in the economic conditions, whether caused by national or local concerns, could 
materially and adversely affect our business. In particular, further deterioration of the economic conditions in Southern California could result in 
the following consequences, any of which could materially and adversely affect our business: loan delinquencies may increase; problem assets 
and foreclosures may increase; demand for our products and services may decrease; low cost or noninterest bearing deposits may decrease; and 
collateral for loans made by us, especially real estate, may decline in value, in turn reducing customers' borrowing power, and reducing the value of 
assets and collateral associated with our existing loans. Until conditions provide for sustainable improvement, we expect our business, financial 
condition and results of operations to be adversely affected.  

Further disruptions in the real estate market could materially and adversely affect our business.  

        There has been a slow-down in the real estate market due to negative economic trends and credit market disruption, the impacts of which are 
not yet completely known or quantified. At December 31, 2011, 75% and 4% of our total gross loans, both non-covered and covered, were 
comprised of real estate mortgage loans and real estate construction loans, respectively. We have observed in the marketplace tighter credit 
underwriting and higher premiums on liquidity, both of which may continue to place downward pressure on real estate values. Any further 
downturn in the real estate market could materially and adversely affect our business because a significant portion of our non-covered loans are 
secured by real estate. Our ability to recover on defaulted non-covered loans by selling the real estate  

25 

 
 
 
 
 
Table of Contents 

collateral would then be diminished and we would be more likely to suffer losses on defaulted non-covered loans. Substantially all of our real 
property collateral is located in Southern California. If there is a further decline in real estate values, especially in Southern California, the collateral 
for our non-covered loans would provide less security. Real estate values could be affected by, among other things, a worsening of the economic 
conditions, an increase in foreclosures, a decline in home sale volumes, an increase in interest rates, continued high levels of unemployment, 
earthquakes and other natural disasters particular to California.  

Our business is subject to interest rate risk, and variations in interest rates may materially and adversely affect our financial performance.  

        Changes in the interest rate environment may reduce our profits. It is expected that we will continue to realize income from the differential or 
"spread" between the interest earned on loans, securities and other interest earning assets, and interest paid on deposits, borrowings and other 
interest bearing liabilities. Net interest spreads are affected by the difference between the maturities and repricing characteristics of interest earning 
assets and interest bearing liabilities. Changes in market interest rates generally affect loan volume, loan yields, funding sources and funding 
costs. Our net interest spread depends on many factors that are partly or completely out of our control, including competition, federal economic 
monetary and fiscal policies, and general economic conditions.  

        While an increase in the general level of interest rates may increase our loan yield, it may adversely affect the ability of certain borrowers with 
variable rate loans to pay the interest on and principal of their obligations. In addition, an increase in market interest rates on loans is generally 
associated with a lower volume of loan originations, which may reduce earnings. Following an increase in the general level of interest rates, our 
ability to maintain a positive net interest spread is dependent on our ability to increase our loan offering rates, replace loan maturities with new 
originations, minimize increases on our deposit rates, and maintain an acceptable level and mix of funding. We cannot provide assurances that we 
will be able to increase our loan offering rates and continue to originate loans due to the competitive landscape in which we operate. Additionally, 
we cannot provide assurances that we can minimize the increases in our deposit rates while maintaining an acceptable level of deposits. Finally, we 
cannot provide any assurances that we can maintain our current levels of noninterest bearing deposits as customers may seek higher yielding 
products when rates increase.  

        Following a decline in the general level of interest rates, our ability to maintain a positive net interest spread is dependent on our ability to 
reduce the interest paid on deposits, borrowings, and other interest bearing liabilities. We cannot provide assurance that we would be able to 
lower the rates paid on deposit accounts to support our liquidity requirements as lower rates may result in deposit outflows.  

        Accordingly, changes in levels of market interest rates could materially and adversely affect our net interest spread, asset quality, loan 
origination volume, liquidity, and overall profitability. We cannot assure you that we can minimize our interest rate risk.  

We face strong competition from financial services companies and other companies that offer banking services which could materially and 
adversely affect our business.  

        We conduct our banking operations primarily in Southern California. Increased competition in our market may result in reduced loans and 
deposits or less favorable loan and deposit terms. Ultimately, we may not be able to compete successfully against current and future competitors. 
Many competitors offer the same banking services that we offer in our service area. These competitors include national banks, regional banks and 
other community banks. We also face competition from many other types of financial institutions, including without limitation, savings and loan 
institutions, finance companies, brokerage firms, insurance companies, credit unions, mortgage banks and other financial intermediaries.  

26 

Table of Contents 

In particular, our competitors include several major financial companies whose greater resources may afford them a marketplace advantage by 
enabling them to maintain numerous banking locations and ATMs and conduct extensive promotional and advertising campaigns.  

        Additionally, banks and other financial institutions with larger capitalization and financial intermediaries not subject to bank regulatory 
restrictions have larger lending limits and are thereby able to serve the credit needs of larger customers. Areas of competition include interest rates 
for loans and deposits, efforts to obtain deposits, and the range and quality of products and services provided, including new technology driven 
products and services. Technological innovation continues to contribute to greater competition in domestic and international financial services 
markets as technological advances enable more companies to provide financial services. We also face competition from out-of-state financial 
intermediaries that have opened production offices or that solicit deposits in our market areas. Should competition in the financial services 
industry intensify, our ability to market our products and services may be adversely affected. If we are unable to attract and retain banking 
customers, we may be unable to grow or maintain the levels of our loans and deposits and our results of operations and financial condition may be 
adversely affected.  

        Competition from financial institutions seeking to maintain adequate liquidity places upward pressure on the rates paid on certain deposit 
accounts relative to the level of market interest rates during times of both decreasing and increasing market liquidity. To maintain both attractive 
and adequate levels of liquidity, without exhausting secondary sources of liquidity, we may incur increased deposit costs.  

        Several rating agencies publish unsolicited ratings of the financial performance and relative financial health of many banks, including Pacific 
Western, based on publicly available data. As these ratings are publicly available, a decline in the Bank's ratings may result in deposit outflows or 
the inability of the Bank to raise deposits in the secondary market as broker- dealers and depositors may use such ratings in deciding where to 
deposit their funds.  

We may need to raise additional capital in the future and such capital may not be available when needed or at all.  

        We may need to raise additional capital in the future to provide us with sufficient capital resources and liquidity to meet our commitments and 
business needs. As a publicly traded company, a likely source of additional funds is the capital markets, accomplished generally through the 
issuance of equity, both common and preferred stock, and the issuance of subordinated debentures. Our ability to raise additional capital, if 
needed, will depend on, among other things, conditions in the capital markets at that time, which are outside of our control, and our financial 
performance. The current economic conditions and the loss of confidence in financial institutions may increase our cost of funding and limit our 
access to some of our customary sources of liquidity, including, but not limited to, the capital markets, inter-bank borrowings, repurchase 
agreements and borrowings from the discount window of the Federal Reserve.  

        We cannot assure you that access to such capital and liquidity will be available to us on acceptable terms or at all. Any occurrence that may 
limit our access to the capital markets, such as a decline in the confidence of debt purchasers, or depositors of the Bank or counterparties 
participating in the capital markets, may materially and adversely affect our capital costs and our ability to raise capital and, in turn, our liquidity. 
An inability to raise additional capital on acceptable terms when needed could have a materially adverse effect on our business.  

We are subject to extensive regulation which could materially and adversely affect our business.  

        Our operations are subject to extensive regulation by federal and state governmental authorities, and we are subject to various laws and 
judicial and administrative decisions imposing requirements and  

27 

Table of Contents 

restrictions on part or all of our operations. The Dodd-Frank Act, enacted in July 2010, instituted major changes to the banking and financial 
institutions regulatory regimes in light of the recent performance of and government intervention in the financial services sector. Regulations 
affecting banks and other financial institutions, such as the Dodd-Frank Act, are undergoing continuous review and change frequently; the 
ultimate effect of such changes cannot be predicted. Because our business is highly regulated, compliance with such regulations and laws may 
increase our costs and limit our ability to pursue business opportunities. Also, participation in specific government stabilization programs may 
subject us to additional restrictions. There can be no assurance that proposed laws, rules and regulations will not be adopted in the future, which 
could (i) make compliance much more difficult or expensive, (ii) restrict our ability to originate, broker or sell loans or accept certain deposits, 
(iii) further limit or restrict the amount of commissions, interest or other charges earned on loans originated or sold by us, or (iv) otherwise 
materially and adversely affect our business or prospects for business.  

        The Dodd-Frank Act will have material implications for the Company and the entire financial services industry. Among other things it will or 
potentially could: 

• 

• 

• 

• 

• 

• 

affect the levels of capital and liquidity with which we must operate and how we plan capital and liquidity levels;  

subject us to new and/or higher fees paid to various regulatory entities, including but not limited to deposit insurance fees to the 
FDIC;  

impact our ability to invest in certain types of entities or engage in certain activities;  

restrict the nature of our incentive compensation programs for executive officers;  

subject us to the new Consumer Financial Protection Bureau, with its very broad rule-making and enforcement authorities; and  

subject us to new and different litigation and regulatory enforcement risks.  

        As the Dodd-Frank Act requires that many studies be conducted and that hundreds of regulations be written in order to fully implement it, the 
full impact of this legislation on us, our business strategies, and financial performance cannot be known at this time, and may not be known for a 
number of years. However, these impacts are expected to be substantial and some of them are likely to adversely affect us and our financial 
performance. The Dodd-Frank Act and related regulations may also require us to invest significant management attention and resources to make 
any necessary changes, and could therefore also adversely affect our business, financial condition and results of operations.  

        Additionally, in order to conduct certain activities, including acquisitions, we are required to obtain regulatory approval. There can be no 
assurance that any required approvals can be obtained, or obtained without conditions or on a timeframe acceptable to us. For more information, 
please see "Item 1. Business—Supervision and Regulation."  

The Dodd-Frank repeal of federal prohibitions on payment of interest on demand deposits could increase our interest expense.  

        All federal prohibitions on the ability of financial institutions to pay interest on demand deposit accounts were repealed as part of the Dodd-
Frank Act. As a result, financial institutions can offer interest on demand deposits to compete for clients. Our interest expense will increase and our 
net interest margin will decrease if the Bank begins offering interest on demand deposits to attract additional customers or maintain current 
customers, which could have a material adverse effect on our business, financial condition and results of operations.

Emergency measures designed to stabilize the U.S. financial system are beginning to wind down.  

        Since the middle of 2008, in addition to the programs initiated under the Emergency Economic Stabilization Act of 2008, other regulators have 
taken steps to attempt to stabilize and add liquidity to the financial markets. Some of these programs have begun to expire and the impact of the 
expiration of these programs on the financial industry and the economic recovery is unknown. A slowdown in or reversal of the economic recovery 
could have a material adverse effect on our business, financial condition and results of operations.  

Increases in or required prepayments of FDIC insurance premiums may adversely affect our earnings.  

        Since 2008, higher levels of bank failures have dramatically increased resolution costs of the FDIC and depleted the deposit insurance fund. In 
addition, the FDIC instituted temporary programs, some of which were made permanent by the Dodd-Frank Act, to further insure customer 
deposits at FDIC insured banks, which have placed additional stress on the deposit insurance fund.  

        In order to maintain a strong funding position and restore reserve ratios of the deposit insurance fund, the FDIC has increased assessment 
rates of insured institutions. In addition, on November 12, 2009, the FDIC adopted a rule requiring banks to prepay three years' worth of premiums 
to replenish the depleted insurance fund.  

        Historically, the FDIC utilized a risk-based assessment system that imposed insurance premiums based upon a risk matrix that takes into 
account several components including but not limited to the bank's capital level and supervisory rating. Pursuant to the Dodd-Frank Act, the FDIC 
amended its regulations to base insurance assessments on the average consolidated assets less the average tangible equity of the insured 
depository institution during the assessment period.  

        We are generally unable to control the amount of premiums that we are required to pay for FDIC insurance. Any future increases in or required 
prepayments of FDIC insurance premiums may adversely affect our financial condition or results of operations.  

Our information systems may experience an interruption or security breach.  

        We rely heavily on communications and information systems to conduct our business. Any failure, interruption or breach in security of these 
systems could result in failures or disruptions in our customer relationship management, general ledger, deposit, loan and other systems. While we 
have policies and procedures designed to prevent or limit the effect of the possible failure, interruption or security breach of our information 
systems, there can be no assurance that any such failure, interruption or security breach will not occur or, if they do occur, that they will be 
adequately addressed. The occurrence of any failure, interruption or security breach of our information systems could damage our reputation, 
result in a loss of customer business, subject us to additional regulatory scrutiny or expose us to civil litigation and possible financial liability.  

We are exposed to transactional, country and legal risk related to our foreign loans that is in addition to risks we face on loans to U.S. based 
borrowers.  

        Approximately 1% of our non-covered loan portfolio is represented by credit we extend and loans we make to businesses located outside the 
United States, predominantly in Mexico. These loans, which include commercial loans, real estate loans and credit extensions for the financing of 
international trade, are subject to risks in addition to risks we face with our loans to businesses located in the United States including, but not 
limited to transaction risk, country risk and legal risk. While these loans are denominated in U.S. dollars, the ability of the borrower to repay may be 
affected by fluctuations in the borrower's home country currency relative to the U.S. dollar. Additionally, while most of our foreign loans are 
insured by U.S.-based institutions, guaranteed by a U.S.-based entity, or collateralized with  

29 

Table of Contents 

U.S.-based assets or real property, our ability to collect in the event of default is subject to a number of conditions, as well as deductibles and co-
payments with respect to insurance, and we may not be successful in obtaining partial or full repayment or reimbursement from the insurers. 
Furthermore, foreign laws may restrict our ability to foreclose on, take a security interest in, or seize collateral located in the foreign country.  

We are exposed to risk of environmental liabilities with respect to properties to which we take title.  

        In the course of our business, we may own or foreclose and take title to real estate, and could be subject to environmental liabilities with 
respect to these properties. We may be held liable to a governmental entity or to third parties for property damage, personal injury, investigation 
and clean-up costs incurred by these parties in connection with environmental contamination, or may be required to investigate or clean up 
hazardous or toxic substances, or chemical releases at a property. The costs associated with investigation or remediation activities could be 
substantial. In addition, as the owner or former owner of a contaminated site, we may be subject to common law claims by third parties based on 
damages and costs resulting from environmental contamination emanating from the property. If we ever become subject to significant 
environmental liabilities, our business, financial condition, liquidity and results of operations could be materially and adversely affected.  

We may not pay dividends on common stock.  

        Our stockholders are only entitled to receive such dividends as our Board of Directors may declare out of funds legally available for such 
payments. Although we have historically declared cash dividends on our common stock, we are not required to do so and may reduce or eliminate 
our common stock dividend in the future. Our ability to pay dividends to our stockholders is subject to the restrictions set forth in Delaware law, 
by our federal regulator, and by certain covenants contained in the indentures governing the trust preferred securities issued by us or entities we 
have acquired. Notification to the FRB is also required prior to our declaring and paying a cash dividend to our stockholders during any period in 
which our quarterly net earnings are insufficient to fund the dividend amount. We may not pay a dividend should the FRB object until such time as 
we receive approval from the FRB or no longer need to provide notice under applicable regulations. See "Item 5. Market for Registrant's Common 
Equity and Related Stockholder Matters—Dividends" for more information on these restrictions. In addition, we may be restricted by applicable 
law or regulation or actions taken by our regulators, or as a result of our participation in any specific government stabilization programs, now or in 
the future, from paying dividends to our stockholders. Accordingly, we cannot assure you that we will continue paying dividends on our common 
stock at current levels or at all. Our failure to pay dividends on our common stock could have a material adverse effect on the market price of our 
common stock.  

The primary source of our income from which, among other things, we pay dividends is the receipt of dividends from the Bank.  

        We are a legal entity separate and distinct from the Bank and our other subsidiaries. The availability of dividends from the Bank is limited by 
various statutes and regulations. It is possible, depending upon the financial condition of the Bank and other factors, that the FRB, the FDIC 
and/or the DFI could assert that payment of dividends or other payments is an unsafe or unsound practice, or that such regulatory authority may 
impose restrictions on the Bank's ability to pay dividends as a condition to the Bank's participation in any stabilization program. In the event the 
Bank is unable to pay dividends to us, it is likely that we, in turn, would have to stop paying dividends on our common stock and may have 
difficulty meeting our other financial obligations, including payments in respect of any outstanding indebtedness or trust preferred securities. The 
inability of the Bank to pay dividends to us could have a material adverse effect on the market price of our common stock. See "Item 1.  

30 

Table of Contents 

Business—Supervision and Regulation" for additional information on the regulatory restrictions to which we and the Bank are subject.  

Only a limited trading market exists for our common stock which could lead to price volatility.  

        Our common stock trades on The NASDAQ Global Select Stock Market under the symbol "PACW" and our trading volume is modest. The 
limited trading market for our common stock may cause fluctuations in the market value of our common stock to be exaggerated, leading to price 
volatility in excess of that which would occur in a more active trading market of our common stock. In addition, even if a more active market in our 
common stock develops, we cannot assure you that such a market will continue or that stockholders will be able to sell their shares.  

Our allowance for credit losses may not be adequate to cover actual losses.  

        In accordance with accounting principles generally accepted in the United States, we maintain an allowance for loan losses to provide for loan 
defaults and non-performance and a reserve for unfunded loan commitments which, when combined, we refer to as the allowance for credit losses. 
Our allowance for credit losses may not be adequate to address actual credit losses, and future provisions for credit losses could materially and 
adversely affect our operating results. Our allowance for credit losses is based on prior experience and an evaluation of the risks in the current 
portfolio. The amount of future losses is susceptible to changes in economic, operating and other conditions, including changes in interest rates 
that may be beyond our control, and these losses may exceed current estimates. Our federal and state regulators, as an integral part of their 
examination process, review our loans and allowance for credit losses. While we believe our allowance for credit losses is appropriate for the risk 
identified in the Company's loan portfolio, we cannot assure you that we will not further increase the allowance for credit losses, that it will be 
sufficient to address losses, or that regulators will not require us to increase this allowance. Any of these occurrences could materially and 
adversely affect our earnings. See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" for more 
information.  

Our acquisitions may subject us to unknown risks.  

        We have completed 23 acquisitions since May 2000, including the MEF acquisition in January 2012 and the FDIC-assisted acquisitions of Los 
Padres Bank in August 2010 and Affinity Bank in August 2009. Certain events may arise after the date of an acquisition, or we may learn of certain 
facts, events or circumstances after the closing of an acquisition, that may affect our financial condition or performance or subject us to risk of 
loss. These events include, but are not limited to: litigation resulting from circumstances occurring at the acquired entity prior to the date of 
acquisition; loan downgrades and credit loss provisions resulting from underwriting of certain acquired loans determined not to meet our credit 
standards; personnel changes that cause instability within a department; delays in implementing new policies or procedures or the failure to apply 
new policies or procedures; and other events relating to the performance of our business. Acquisitions involve inherent uncertainty and we 
cannot determine all potential events, facts and circumstances that could result in loss or give assurances that our investigation or mitigation 
efforts will be sufficient to protect against any such loss.  

We are dependent on key personnel and the loss of one or more of those key personnel may materially and adversely affect our prospects.  

        We currently depend heavily on the services of our chairman, John Eggemeyer, our chief executive officer, Matthew Wagner, and a number of 
other key management personnel. The loss of Mr. Eggemeyer's or Mr. Wagner's services or that of other key personnel could materially and 
adversely affect our results of operations and financial condition. Our success also depends, in part, on our ability to attract and retain additional 
qualified management personnel. Competition for such  

31 

Table of Contents 

personnel is strong in the banking industry, and we may not be successful in attracting or retaining the personnel we require.  

Concentrated ownership of our common stock creates a risk of sudden changes in our share price.  

        As of March 2, 2012, directors and members of our executive management team owned or controlled approximately 4% of our common stock, 
excluding shares that may be issued to executive officers upon vesting of restricted stock awards. Investors who purchase our common stock may 
be subject to certain risks due to the concentrated ownership of our common stock. The sale by any of our large stockholders of a significant 
portion of that stockholder's holdings could have a material adverse effect on the market price of our common stock. In addition, the registration of 
any significant amount of additional shares of our common stock will have the immediate effect of increasing the public float of our common stock 
and any such increase may cause the market price of our common stock to decline or fluctuate significantly.  

Our largest stockholder is a registered bank holding company, and the activities and regulation of such stockholder may materially and 
adversely affect the permissible activities of the Company.  

        CapGen Capital Group II LP, which we refer to as CapGen, beneficially owned approximately 11% of the Company as of March 2, 2012. CapGen 
is a registered bank holding company under the BHCA and is regulated by the FRB. Under the Dodd-Frank Act and related regulations, bank 
holding companies must be a "source of strength" for their subsidiaries. See "Item 1. Business—Supervision and Regulation—Bank Holding 
Company Regulation" for more information. Regulation of CapGen by the FRB may materially and adversely affect the activities and strategic plans 
of the Company should the FRB determine that CapGen or any other company in which either has invested has engaged in any unsafe or unsound 
banking practices or activities. While we have no reason to believe that the FRB is proposing to take any action with respect to CapGen that would 
adversely affect the Company, we remain subject to such risk.  

A natural disaster could harm the Company's business.  

        Historically, California, in which a substantial portion of the Company's business is located, has been susceptible to natural disasters, such as 
earthquakes, floods and wild fires. The nature and level of natural disasters cannot be predicted and may be exacerbated by global climate change. 
These natural disasters could harm the Company's operations through interference with communications, including the interruption or loss of the 
Company's computer systems, which could prevent or impede the Company from gathering deposits, originating loans and processing and 
controlling its flow of business, as well as through the destruction of facilities and the Company's operational, financial and management 
information systems. Additionally, natural disasters could negatively impact the values of collateral securing the Company's loans and interrupt 
our borrowers' abilities to conduct their business in a manner to support their debt obligations, either of which could result in losses and increased 
provisions for credit losses.  

Our decisions regarding the fair value of assets acquired, including the FDIC loss sharing asset, could be inaccurate which could materially 
and adversely affect our business, financial condition, results of operations, and future prospects.  

        Management makes various assumptions and judgments about the collectibility of the acquired loans, including the creditworthiness of 
borrowers and the value of the real estate and other assets serving as collateral for the repayment of secured loans. In FDIC-assisted acquisitions 
that include loss sharing agreements, we may record a loss sharing asset that we consider adequate to absorb future losses which may occur in the 
acquired loan portfolio. In determining the size of the loss sharing asset, we analyze the loan portfolio based on historical loss experience, volume 
and classification of loans,  

32 

Table of Contents 

volume and trends in delinquencies and nonaccruals, local economic conditions, and other pertinent information. If our assumptions are incorrect, 
the balance of the FDIC loss sharing asset may at any time be insufficient to cover future loan losses, and credit loss provisions may be needed to 
respond to different economic conditions or adverse developments in the acquired loan portfolio. Any increase in future losses on loans and other 
assets covered by loss sharing agreements could have a negative effect on our operating results.  

Our ability to obtain reimbursement under the loss sharing agreements on covered assets depends on our compliance with the terms of the loss 
sharing agreements.  

        Management must certify to the FDIC on a quarterly basis our compliance with the terms of the FDIC loss sharing agreements as a 
prerequisite to obtaining reimbursement from the FDIC for realized losses on covered assets. The required terms of the agreements are extensive 
and failure to comply with any of the guidelines could result in a specific asset or group of assets temporarily or permanently losing their loss 
sharing coverage. Additionally, management may decide to forgo loss share coverage on certain assets to allow greater flexibility over the 
management of certain assets. As of December 31, 2011, $781.7 million, or 14.1%, of the Company's assets were covered by FDIC loss sharing 
agreements.  

        Under the terms of the FDIC loss sharing agreements, the assignment or transfer of the loss sharing agreement to another entity generally 
requires the written consent of the FDIC. Based on the manner in which assignment is defined in the agreements, each of the following requires the 
prior written consent of the FDIC:  

1. 

2. 

3. 

a merger or consolidation of the Bank with and into another financial institution;  

the sale of all or substantially all of the Bank's assets to another financial institution; and  

with respect to covered assets acquired in the Affinity acquisition, for a period of 36 months after the August 28, 2009 acquisition 
date  

a. 

b. 

the sale by any individual shareholder, or shareholders acting in concert, of more than 9% of the outstanding shares of 
either the Bank or the Company;  

the sale of shares by the Bank or the Company in a public or private offering that increases the number of shares 
outstanding of either the Bank or the Company by more than 9%.  

        No assurances can be given that we will manage the covered assets in such a way as to always maintain loss share coverage on all such 
assets.

ITEM 2.    PROPERTIES  

        As of March 1, 2012, we had a total of 97 properties consisting of 76 operating branch offices, two annex offices, three operations centers, 10 
loan production offices, and six other properties. We own eight locations and the remaining properties are leased. Almost all properties are located 
in Southern California. Pacific Western's principal office is located at 10250 Constellation Blvd., Suite 1640, Los Angeles, CA 90067.  

        For additional information regarding properties of the Company and Pacific Western, see Note 9, Premises and Equipment, Net, of the Notes

ITEM 3.    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, would not have a material adverse effect 
on the Company's financial statements or operations.

        As of March 2, 2012, the closing price of our common stock on Nasdaq was $21.26 per share. As of that date, based on the records of our 
transfer agent, there were approximately 1,598 record holders of our common stock.  

Dividends  

        Our ability to pay dividends to our stockholders is subject to the restrictions set forth in the Delaware General Corporation Law, or the DGCL. 
The DGCL provides that a corporation, unless otherwise restricted by its certificate of incorporation, may declare and pay dividends out of its 
surplus or, if there is no surplus, out of net profits for the fiscal year in which the dividend is declared and/or for the preceding fiscal year, as long 
as the amount of capital of the corporation is not less than the aggregate amount of the capital represented by the issued and outstanding stock of 
all classes having a preference upon the distribution of assets. Surplus is defined as the excess of a corporation's net assets (i.e., its total assets 
minus its total liabilities) over the capital associated with issuances of its common stock. Moreover, DGCL permits a board of directors to reduce its 
capital and transfer such amount to its surplus. In determining the amount of surplus of a Delaware corporation, the assets of the corporation, 
including stock of subsidiaries owned by the corporation, must be valued at their fair market value as determined by the board of directors, 
regardless of their historical book value. Our ability to pay dividends is also subject to certain other limitations. See "Item 1. Business—
Supervision and Regulation" and Note 19, Dividend Availability and Regulatory Matters, of the Notes to Consolidated Financial Statements 
contained in "Item 8. Financial Statements and Supplementary Data."  

        Set forth in the table above are the dividends declared and paid by the Company during the two most recent fiscal years. Our ability to pay 
cash dividends to our stockholders is also limited by certain covenants contained in the indentures governing trust preferred securities issued by 
us or entities that we have acquired, and the debentures underlying the trust preferred securities. Generally the indentures provide that if an Event 
of Default (as defined in the indentures) has occurred and is

continuing, or if we are in default with respect to any obligations under our guarantee agreement which covers payments of the obligations on the 
trust preferred securities, or if we give notice of any intention to defer payments of interest on the debentures underlying the trust preferred 
securities, then we may not, among other restrictions, declare or pay any dividends with respect to our common stock. Notification to the FRB is 
also required prior to our declaring and paying a cash dividend to our stockholders during any period in which our quarterly net earnings are 
insufficient to fund the dividend amount. Under such circumstances, we may not pay a dividend should the FRB object until such time as we 
receive approval from the FRB or no longer need to provide notice under applicable regulations.  

        Holders of Company common stock are entitled to receive dividends declared by the Board of Directors out of funds legally available under 
state law governing the Company and certain federal laws and regulations governing the banking and financial services business. During 2011, 
2010, and 2009, the Company paid $7.6 million, $1.4 million, and $11.1 million, respectively, in cash dividends on common stock.  

        We can provide no assurance that we will continue to declare dividends on a quarterly basis or otherwise. The declaration of dividends by the 
Company is subject to the discretion of our Board of Directors. Our Board of Directors will take into account such matters as general business 
conditions, our financial results, projected cash flows, capital requirements, contractual, legal and regulatory restrictions on the payment of 
dividends by us to our stockholders or by our subsidiary to the holding company, and such other factors as our Board of Directors may deem 
relevant.  

        PacWest's primary source of income is the receipt of cash dividends from the Bank. The availability of cash dividends from the Bank is limited 
by various statutes and regulations. It is possible, depending upon the financial condition of the bank in question, and other factors, that the FRB, 
the FDIC or the DFI could assert that payment of dividends or other payments is an unsafe or unsound practice. Pacific Western is subject to 
restrictions under certain federal and state laws and regulations governing banks which limit its ability to transfer funds to the holding company 
through intercompany loans, advances or cash dividends.  

        Dividends paid by state banks, such as Pacific Western, are regulated by the DFI under its general supervisory authority as it relates to a 
bank's capital requirements. A state bank may declare a dividend without the approval of the DFI as long as the total dividends declared in a 
calendar year do not exceed either the retained earnings or the total of net earnings for three previous fiscal years less any dividend paid during 
such period. During 2011, the Bank paid $25.5 million in dividends to the Company. For the foreseeable future, any further cash dividends from the 
Bank to the Company will require DFI approval. See "Item 1. Business—Supervision and Regulation," for further discussion of potential regulatory 
limitations on the holding company's receipt of funds from the Bank, as well as "Item 7. Management's Discussion and Analysis of Financial 
Condition and Results of Operations—Liquidity" and Note 19, Dividend Availability and Regulatory Matters, of the Notes to Consolidated 
Financial Statements contained in "Item 8. Financial Statements and Supplementary Data" for a discussion of other factors affecting the availability 
of dividends and limitations on the ability to declare dividends.

Five-Year Stock Performance Graph  

        The following chart compares the yearly percentage change in the cumulative shareholder return on our common stock based on the closing 
price during the five years ended December 31, 2011, with (1) the Total Return Index for U.S. companies traded on The Nasdaq Stock Market (the 
"NASDAQ Composite"), and (2) the Total Return Index for the KBW Regional Bank Stocks (the "KBW Regional Banking Index"). This 
comparison assumes $100 was invested on December 31, 2006, in our common stock and the comparison groups and assumes the reinvestment of 
all cash dividends prior to any tax effect and retention of all stock dividends. PacWest's total cumulative loss was 59.4% over the five year period 
ending December 31, 2011 compared to a gain of 10.8% and loss of 33.6% for the NASDAQ Composite and KBW Regional Banking Index, 
respectively.

ITEM 7.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS  

        This section should be read in conjunction with the disclosure regarding "Forward-Looking Statements" set forth in "Item 1. Business—
Forward-Looking Statements", as well as the discussion set forth in "Item 1. Business—Certain Business Risks" and "Item 8. Financial 
Statements and Supplementary Data," including the notes to consolidated financial statements. 

Overview  

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

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

        Over the last year, the Company's assets have essentially remained flat, declining $784,000 to $5.5 billion at December 31, 2011. The change 
was due primarily to decreases of $353.3 million, $205.6 million, $50.2 million, and $21.2 million in gross non-covered loans, covered loans, other 
assets, and FDIC loss sharing asset, respectively. These decreases were offset partially by increases of $452.3 million in securities available-for-
sale attributable to purchases using excess liquidity and $176.9 million in interest-earning deposits in financial institutions attributable mostly to 
principal payments received on loans and investment securities. At December 31, 2011, gross non-covered loans, securities available-for-sale, and 
covered loans totaled $2.8 billion, $1.3 billion, and $703 million, respectively, or 51%, 24%, and 13% of total assets, respectively.  

        Pacific Western competes actively for deposits and emphasizes solicitation of noninterest-bearing deposits. In managing the top line of our 
business, we focus on loan growth, loan yield, deposit cost, and net interest margin, as net interest income accounted for 89% of our net revenues 
(net interest income plus noninterest income) for 2011.  

        We have completed 23 business acquisitions since the Company's inception in 1999, including the purchase of Marquette Equipment Finance 
in January 2012 and the FDIC-assisted acquisitions of Los Padres Bank and Affinity Bank in August 2010 and August 2009, respectively. These 
acquisitions affect the comparability of our reported financial information as the operating results of the acquired entities are included in our 
operating results only from their respective acquisition dates. For further information on our acquisitions, see Note 3, Acquisitions, and Note 4, 
Goodwill and Other Intangible Assets, of the Notes to Consolidated Financial Statements included in "Item 8. Financial Statement and 
Supplementary Data."

Marquette Equipment Finance Acquisition  

        On January 3, 2012, Pacific Western Bank completed the acquisition of Marquette Equipment Finance, or MEF, an equipment leasing company 
located in Midvale, Utah. Pacific Western Bank acquired all of the capital stock of MEF from Meridian Bank, N.A. for $35 million in cash. MEF 
focuses on business-essential equipment leases throughout the United States with transactions primarily in the mid-ticket segment. This 
acquisition diversifies our loan portfolio, expands our product line, and provides growth opportunities. It also importantly deployed our excess 
liquidity into higher-yielding assets.  

        At January 3, 2012, MEF had $162.2 million in gross leases and leases in process outstanding, with no leases on nonaccrual status. MEF's 
leases are spread across 18 industries, with the top three being financial services/insurance, manufacturing, and health care and representing 68% 
of the lease portfolio balance. The weighted average yield on the lease portfolio at year end 2011 was approximately 9% and its weighted average 
remaining maturity was 34 months. In addition, Pacific Western Bank assumed $154.8 million in outstanding debt and other liabilities, which 
included $129 million payable to MEF's former parent. Pacific Western Bank repaid MEF's intercompany debt on the closing date from its excess 
liquidity on deposit at the Federal Reserve Bank. This resulted in MEF's interest-earning assets being funded with our low-cost deposit base.  

        Effective March 23, 2012, MEF will change its name to Pacific Western Equipment Finance and operate under this name as a division of Pacific 
Western Bank. Pacific Western Bank retained all 71 MEF employees.  

        The following table presents the MEF balance sheet presented at fair value as of the acquisition date, January 3, 2012:

2010 Material Loan Activity  

Non-Covered Classified Loan Sales  

        During 2010, we made strategic decisions to sell $398.5 million of non-covered classified loans to reduce credit risk, thereby strengthening the 
Bank's balance sheet and enhancing its ability to continue to participate in bidding on FDIC-assisted acquisitions. The loans sold included 
$128.1 million in nonaccrual loans and $148.8 million in performing restructured loans. All of the loans sold were

originated by Pacific Western Bank and none were covered loans acquired in the Los Padres Bank or Affinity Bank acquisitions. These sales were 
for cash of $254.6 million and were completed on a servicing-released basis and without recourse to Pacific Western Bank. Such sales resulted in 
immediate reductions of non-covered classified loans and improved credit quality metrics.  

        These sales resulted in a charge-off to the allowance for credit losses of $143.9 million, of which $58.2 million had been previously allocated to 
the loans sold through our allowance methodology and $85.7 million represented the market discount necessary for the loans to be sold to the 
buyer.  

Loan Portfolio Purchase  

        On July 1, 2010, we purchased a $234.1 million portfolio of 225 performing loans secured by Southern California real estate for a cash price of 
$228.3 million. These loans were part of the Foothill Independent Bank loan portfolio that we acquired when we completed the Foothill 
Independent Bancorp acquisition in May 2006. In March 2007, we had sold a 95% participating interest in these loans for cash and continued to 
service them and maintain the borrower relationships. When the opportunity to purchase this loan portfolio presented itself, we concluded it 
would be in the best interests of the Company and the Bank to make this purchase as we are familiar with the credit risk and it would deploy excess 
liquidity in a manner that would increase interest income and expand the net interest margin. As of December 31, 2011, such portfolio totaled 
$179.4 million.  

FDIC-Assisted Acquisitions  

        The estimated losses expected to be collected from the FDIC under the terms of the loss share agreements for the Los Padres and Affinity 
acquisitions are reflected in the loss share receivable. We file claims to the FDIC for the losses incurred on covered assets on a quarterly basis in 
the calendar month following each quarter-end. We received reimbursement from the FDIC, subject to their satisfactory review of our loss share 
claim certificates. As of January 2012, we have filed claims to the FDIC for losses on covered assets through the fourth quarter of 2011 in an 
aggregate amount of $191.7 million. We have received payment from the FDIC of $149.4 million, which represents 80% of our losses, and we expect 
to receive $3.9 million for recently submitted claims.  

2010 Los Padres Acquisition  

        On August 20, 2010, we acquired certain assets of Los Padres Bank, including all loans, and assumed substantially all of its liabilities, 
including all deposits, from the FDIC in an FDIC-assisted acquisition, which we refer to as the Los Padres acquisition. Pacific Western (i) acquired 
$437.1 million in loans, $33.9 million in other real estate owned, $44.3 million in investments, and $261.5 million in cash and other assets, and 
(ii) assumed $752.2 million in deposits, $70.0 million in borrowings, and $1.9 million in other liabilities. In connection with the Los Padres 
acquisition, the FDIC made a cash payment to Pacific Western of $144.0 million. Other than a deposit premium of $3.4 million, we paid no cash or 
other consideration to acquire Los Padres. The estimated fair value of the liabilities assumed exceeded the estimated fair value of the assets 
acquired and we recorded $47.3 million of goodwill.  

        We entered into a loss sharing agreement with the FDIC, whereby the FDIC agreed to cover a substantial portion of any future losses on the 
acquired loans, with the exception of consumer loans, and other real estate owned. We refer to the acquired assets subject to the loss sharing 
agreement collectively as "covered assets." Under the terms of such loss sharing agreement, the FDIC is obligated to reimburse the Bank for 80% 
of losses with respect to the covered assets. The Bank will reimburse the FDIC for 80% of recoveries with respect to losses for which the FDIC 
paid the Bank 80% reimbursement under the loss sharing agreement. The loss sharing provisions for single family covered assets and commercial 
(non-single family) covered assets are in effect for 10 years and 5 years,  

43 

Table of Contents 

respectively, from the acquisition date, and the loss recovery provisions are in effect for 10 years and 8 years, respectively, from the acquisition 
date.  

        Los Padres was a federally chartered savings bank headquartered in Solvang, California that operated 14 branches, including 11 branches in 
California (three in Ventura County, four in Santa Barbara County, and four in San Luis Obispo County) and three branches in Arizona (Maricopa 
County). After office consolidations in 2011, we are operating eight of the former Los Padres branch offices, all of which are located in California. 
We made this acquisition to expand our presence in the Central Coast of California.  

        The assets acquired and liabilities assumed are 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 August 20, 2010 acquisition date. The application of the acquisition 
method of accounting resulted in goodwill of $47.3 million. Such goodwill included $9.5 million related to the FDIC's settlement accounting for a 
wholly-owned subsidiary of Los Padres. We disagreed with the FDIC's accounting for this item and during 2011 we successfully resolved this 
matter with the FDIC through a cash receipt of $7.6 million and a goodwill reduction for the same amount. See Note 3, Acquisitions, and Note 4, 
Goodwill and Other Intangible Assets, of the Notes to Consolidated Financial Statements contained in "Item 8. Financial Statements and 
Supplementary Data" for additional information regarding the Los Padres acquisition.  

2009 Affinity Acquisition  

        On August 28, 2009, we acquired substantially all of the assets of Affinity Bank, including all loans, and assumed substantially all of its 
liabilities, including the insured and uninsured deposits and excluding certain brokered deposits, from the FDIC in an FDIC-assisted transaction, 
which we refer to as the Affinity acquisition. Pacific Western (i) acquired $675.6 million in loans, $22.9 million in foreclosed assets, $175.4 million in 
investments and $371.5 million in cash and other assets, and (ii) assumed $868.2 million in deposits, $305.8 million in borrowings, and $32.6 million 
in other liabilities. In connection with the Affinity acquisition, the FDIC made a cash payment to Pacific Western of $87.2 million.  

        We entered into a loss sharing agreement with the FDIC, whereby the FDIC agreed to cover a substantial portion of any future losses on 
acquired loans, other real estate owned and certain investment securities. We refer to the acquired assets subject to the loss sharing agreement 
collectively as "covered assets." Under the terms of such loss sharing agreement, the FDIC will absorb 80% of losses and receive 80% of loss 
recoveries on the first $234 million of losses on covered assets and absorb 95% of losses and receive 95% of loss recoveries on covered assets 
exceeding $234 million. The loss sharing provisions are in effect for 5 years for commercial assets (non-residential loans, OREO and certain 
securities) and 10 years for residential loans from the August 28, 2009 acquisition date. The loss recovery provisions are in effect for 8 years for 
commercial assets and 10 years for residential loans from the acquisition date.  

        Affinity was a full service commercial bank headquartered in Ventura, California that operated 10 branch locations in California, all of which we 
continue to operate. We made this acquisition to expand our presence in California.  

        The acquisition has been accounted for under the acquisition method of accounting. Accordingly the acquired assets, including the FDIC 
loss sharing asset and identifiable intangible asset, and the assumed liabilities were recorded at their estimated fair values as of the August 28, 
2009 acquisition date. The application of the acquisition method of accounting resulted in a gain of $67.0 million ($38.9 million after-tax). Such gain 
represented the excess of the estimated fair value of the assets acquired over the estimated fair value of the liabilities assumed. See Note 3, 
Acquisitions, and Note 4, Goodwill and Other Intangible Assets, of the Notes to Consolidated Financial Statements contained in  

44 

Table of Contents 

"Item 8. Financial Statements and Supplementary Data" for additional information regarding the Affinity acquisition.  

Key Performance Indicators  

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

The Level of Our Net Interest Income  

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

        Our primary interest-earning assets are loans and investments. Our primary interest-bearing liabilities are deposits. We attribute our high net 
interest margin to our high level of noninterest-bearing deposits and low cost of deposits. While our deposit balances will fluctuate depending on 
deposit holders' perceptions of alternative yields available in the market, we attempt to minimize these variances by attracting a high percentage of 
noninterest-bearing deposits, which have no expectation of yield. At December 31, 2011, approximately 37% of our total deposits were noninterest-
bearing.  

Loan Growth  

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

The Magnitude of Credit Losses  

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

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

45 

 
Table of Contents  

The Level of Our Noninterest Expense  

        Our noninterest expense includes fixed and controllable overhead, the major components of which are compensation, occupancy, data 
processing, and other professional services. It also includes costs that tend to vary based on the volume of activity, such as OREO expense. We 
measure success in controlling both fixed and variable costs through monitoring of the efficiency ratio. We calculate the base efficiency ratio by 
dividing noninterest expense by net revenues (the sum of net interest income plus noninterest income). We also calculate a non-GAAP measure 
called the "credit cost adjusted efficiency ratio." The credit cost adjusted efficiency ratio is calculated in the same manner as the base efficiency 
ratio except that noninterest income is reduced by FDIC loss sharing income and noninterest expense is reduced by OREO expenses. See 
calculations in "Non-GAAP Measurements" contained herein.  

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

Quarterly Period in 2011 
First 
Second 
Third 
Fourth 

Base

Ratio

58.2% 
67.9% 
60.4% 

60.4%
57.7%
58.7%
59.9%

        The base efficiency ratio fluctuations shown in the above table result from the volatility of FDIC loss sharing income and OREO expenses. The 
credit cost adjusted efficiency ratio eliminates such volatility and shows the trend in overhead related noninterest expense relative to net revenues.  

Critical Accounting Policies  

        The following discussion and analysis of financial condition and results of operations are based upon our consolidated financial statements 
and the notes thereto, which have been prepared in accordance with accounting principles generally accepted in the United States. The 
preparation of the consolidated financial statements requires us to make a number of estimates and assumptions that affect the reported amounts 
and disclosures in the consolidated financial statements. On an ongoing basis, we evaluate our estimates and assumptions based upon historical 
experience and various other factors and circumstances. We believe that our estimates and assumptions are reasonable; however, actual results 
may differ significantly from these estimates and assumptions which could have a material impact on the carrying value of assets and liabilities at 
the balance sheet dates and on our results of operations for the reporting periods.  

        Our significant accounting policies and practices are described in Note 1, Nature of Operations and Summary of Significant Accounting 
Policies, of the Notes to Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data." The accounting 
policies that involve significant estimates and assumptions by management, which have a material impact on the carrying value of certain assets 
and liabilities, are considered critical accounting policies. We have identified our policies for the allowances for credit losses, the carrying values of 
intangible assets, and deferred income tax assets as critical accounting policies.  

Allowance for Credit Losses on Non-Covered Loans  

        The allowance for credit losses on non-covered loans is the combination of the allowance for loan losses and the reserve for unfunded loan 
commitments. The allowance for credit losses on non-covered loans relates only to loans which are not subject to loss sharing agreements with the 
FDIC. The allowance for loan losses is reported as a reduction of outstanding loan balances and the reserve for unfunded loan commitments is 
included within other liabilities. Generally, as loans are funded, the  

46 

 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents 

amount of the commitment reserve applicable to such funded loans is transferred from the reserve for unfunded loan commitments to the allowance 
for loan losses based on our allowance methodology. The following discussion is for non-covered loans and the allowance for credit losses 
thereon. Refer to "—Allowance for Credit Losses on Covered Loans" for the policy on covered loans.  

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

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

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

        Impaired loans are identified at each reporting date based on certain criteria and the majority of which are individually reviewed for impairment. 
Non-covered nonaccrual loans with an unpaid principal balance over $250,000 and all performing restructured loans are reviewed individually for 
the amount of impairment, if any. Non-covered nonaccrual loans with an unpaid principal balance of $250,000 or less are evaluated for impairment 
collectively. The population of such loans totaled $4.3 million, represented by 64 loans, as of December 31, 2011. A loan is considered impaired 
when it is probable that a creditor will be unable to collect all amounts due according to the original contractual terms of the loan agreement. We 
measure impairment of a loan based upon the fair value of the loan's collateral if the loan is collateral dependent or the present value of cash flows, 
discounted at the loan's effective interest rate, if the loan is not collateral-dependent. The impairment amount on a collateral-dependent loan is 
charged-off to the allowance and the impairment amount on a loan that is not collateral-dependent is set up as a specific reserve. Increased charge-
offs or additions to specific reserves generally result in increased provisions for credit losses.  

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

• 

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

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

        In addition, we may refer to the loans classified as "substandard" and "doubtful" together as "criticized loans." For further information on 
classified loans, see Note 6, Loans, of the Notes to Consolidated Financial Statements contained in "Item 8. Financial Statements and 
Supplementary Data."  

        The allowance amounts for "pass" rated loans and those loans adversely classified, which are not reviewed individually, are determined using 
historical loss rates developed through migration analysis. The migration analysis is updated quarterly based on historic losses and movement of 
loans between ratings.  

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

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

        We recognize that the determination of the allowance for loan losses is sensitive to the assigned credit risk ratings and inherent loss rates at 
any given point in time. Therefore, we perform sensitivity analyses to provide insight regarding the impact adverse changes in credit risk ratings 
may have on our allowance for loan losses. The sensitivity analyses have inherent limitations and are based on various assumptions as of a point 
in time and, accordingly, it is not necessarily representative of the impact loan risk rating changes may have on the allowance for loan losses.  

        At December 31, 2011, in the event that 1% of our non-covered loans were downgraded one credit risk rating category for each category 
(e.g., 1% of the "pass" category moved to the "special mention" category, 1% of the "special mention" category moved to "substandard" 
category, and 1% of the "substandard" category moved to the "doubtful" category within our current allowance methodology), the allowance for 
credit losses would have increased by approximately $1.4 million. In the event that 5% of our non-covered loans were downgraded one credit risk 
category, the allowance for credit losses would increase by approximately $7.2 million. Given current processes employed by the Company, 
management believes the credit risk ratings and inherent loss rates currently assigned are appropriate. It is possible that others, given the same 
information, may at any point in time reach different conclusions that could be significant to the Company's financial statements. In addition, 
current credit

risk ratings are subject to change as we continue to review loans within our portfolio and as our borrowers are impacted by economic trends within 
their market areas.  

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

Allowance for Credit Losses on Covered Loans  

        The loans acquired in the Los Padres and Affinity acquisitions are covered by loss sharing agreements with the FDIC and we will be 
reimbursed for a substantial portion of any future losses. Under the terms of the Los Padres loss sharing agreement, the FDIC will absorb 80% of 
losses and receive 80% of loss recoveries on the covered assets. The loss sharing provisions are in effect for 10 years for single family covered 
assets and 5 years for commercial (non-single family) covered assets from the August 20, 2010 acquisition date. The loss recovery provisions are 
in effect for 10 years for single family assets and 8 years for commercial (non-single family) assets from the acquisition date. Under the terms of the 
Affinity loss sharing agreement, the FDIC will absorb 80% of losses and receive 80% of loss recoveries on the first $234 million of losses on 
covered assets and absorb 95% of losses and receive 95% of loss recoveries on covered assets exceeding the $234 million threshold. Through 
December 31, 2011, gross losses for Affinity covered assets totaled $144.6 million and gross losses for Los Padres covered assets totaled 
$47.1 million. The loss sharing provisions are in effect for 10 years for residential loans and 5 years for commercial assets (non-residential loans, 
OREO and certain securities) from the August 28, 2009 acquisition date. The loss recovery provisions are in effect for 10 years for residential loans 
and 8 years for commercial assets from the acquisition date.  

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

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

        Certain home equity lines of credit acquired in the Los Padres acquisition are not eligible for acquired impaired loan accounting and are 
therefore accounted for as performing acquired loans. Such acquired loans were initially recorded at a discount and are subject to our quarterly 
allowance for credit losses methodology. We record a provision for such loan losses only when the reserve requirement exceeds any remaining 
credit discount on these covered loans. Please see "—Financial Condition—Allowance for Credit Losses on Covered Loans" and Note 1(h), 
Nature of Operations and Summary of Significant Accounting Policies—Impaired Loans and Allowances for Credit Losses, and Note 6, Loans, 
of the Notes to Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data" for more information.

Goodwill and Other Intangible Assets  

        Goodwill and intangible assets arise from purchase business combinations. Goodwill and other intangible assets generated from purchase 
business combinations and deemed to have indefinite lives are not subject to amortization and are instead tested for impairment at least annually. 
Intangible assets with definite lives arising from business combinations are tested for impairment quarterly.  

        Our other intangible assets with definite lives include core deposit and customer relationship intangibles. The establishment and subsequent 
amortization of these intangible assets requires several assumptions including, among other things, the estimated cost to service deposits 
acquired, discount rates, estimated attrition rates and useful lives. These intangibles are being amortized over their estimated useful lives up to 
10 years and tested for impairment quarterly. If the value of the core deposit intangible or the customer relationship intangible is determined to be 
less than the carrying value in future periods, a write-down would be taken through a charge to our earnings. The most significant element in 
evaluation of these intangibles is the attrition rate of the acquired deposits or loan relationships. If such attrition rate were to accelerate from that 
which we expected, the intangible may have to be reduced by a charge to earnings. The attrition rate related to deposit flows or loan flows is 
influenced by many factors, the most significant of which are alternative yields for loans and deposits available to customers and the level of 
competition from other financial institutions and financial services companies.  

Deferred Income Tax Assets  

        Our deferred income tax assets arise from differences between the financial statement carrying amounts of existing assets and liabilities and 
their respective tax bases and net operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax 
rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. From an 
accounting standpoint, we determine whether a deferred tax asset is realizable based on facts and circumstances, including the Company's current 
and projected future tax position, the historical level of our taxable income, and estimates of our future taxable income. In most cases, the realization 
of deferred tax assets is based on our future profitability. If we were to experience either reduced profitability or operating losses in a future period, 
the realization of our deferred tax assets may no longer be considered more likely than not that they will be realized. In such an instance, we could 
be required to record a valuation allowance on our deferred tax assets by charging earnings.  

Non-GAAP Measurements  

        Certain discussion in this Form 10-K contains non-GAAP financial disclosures for tangible common equity, pre-credit, pre-tax earnings, and a 
credit cost adjusted efficiency ratio. The Company uses certain non-GAAP financial measures to provide meaningful supplemental information 
regarding the Company's operational performance and to enhance investors' overall understanding of such financial performance. Given the use of 
tangible common equity amount and ratio is prevalent among banking regulators, investors and analysts, we disclose our tangible common equity 
ratio in addition to equity-to-assets ratio. Also, as analysts and investors view pre-credit, pre-tax earnings as an indicator of the Company's ability 
to absorb credit losses, we disclose this amount in addition to net earnings. The methodology of determining tangible common equity and pre-
credit, pre-tax earnings may differ among companies. We disclose the credit cost adjusted efficiency ratio as it eliminates the volatility of FDIC loss 
sharing income and OREO expenses from the base efficiency ratio and shows the trend in overhead related noninterest expense relative to net 
revenues. These non-GAAP financial measures are presented for supplemental informational purposes only for understanding the Company's 
financial condition and operating results and should not be considered a substitute for financial information presented in accordance with United 
States generally accepted accounting principles ("GAAP").

Fourth Quarter of 2011 Compared to Third Quarter of 2011  

        We recorded net earnings of $13.9 million for the fourth quarter of 2011 compared to net earnings of $13.3 million for the third quarter of 2011. 
The $579,000 increase in net earnings for the linked quarters was due to lower covered OREO costs of $4.6 million ($2.7 million after tax) and higher 
FDIC loss sharing income of $1.7 million ($1.0 million after tax), offset by a higher provision for credit losses on covered loans of $3.8 million 
($2.2 million after tax) and lower net interest income of $668,000 ($387,000 after tax).  

        Net interest income was $63.8 million for the fourth quarter of 2011 compared to $64.4 million for the third quarter of 2011. The $668,000 decline 
was due to a $1.7 million decrease in loan interest income from lower average loans. Offsetting the decline in interest income was a reduction in 
interest expense of $937,000 due to lower rates on all interest-bearing deposits and a decline in average time deposits.  

        Our net interest margin for the fourth quarter of 2011 was 5.00%, a decrease of 15 basis points from the 5.15% reported for the third quarter of 
2011. The decrease reflected a shift in the mix of average interest-earning assets to lower yielding investment securities from higher yielding loans 
and lower

accelerated accretion of discounts on covered loan payoffs. Average interest-earning assets increased $91.1 million for the linked quarters 
including a $141.1 million increase in average investment securities. The yield on average loans was 6.87% for the fourth and third quarters of 2011. 
The yield on average non-covered loans was 6.49% and 6.53% for the fourth and third quarters, respectively, while the yield on average covered 
loans was 8.35% and 8.13%, respectively. The combination of accelerated accretion of discounts on covered loan payoffs and nonaccrual loan 
interest positively impacted the loan yield for the fourth quarter by 4 basis points and the third quarter by 17 basis points. The cost of interest-
bearing deposits declined 12 basis points to 0.57% due to lower rates on interest-bearing deposits and lower average time deposits, and all-in 
deposit cost declined 8 basis points to 0.36%.

        The provision for credit losses for the fourth and third quarters totaled $4.1 million and $348,000, respectively; such provisions related only to 
the covered loan portfolio. The zero provision level on the non-covered portfolio is generated by our allowance methodology and reflects net 
charge-offs, the levels of nonaccrual and classified loans, and the migration of loans into various risk classifications. The provision for credit 
losses on the covered loans results from decreases in expected cash flows on covered loans compared to those previously estimated.  

        Net charge-offs on non-covered loans for the fourth quarter of 2011 totaled $2.8 million compared to third quarter net charge-offs of 
$6.0 million. The allowance for credit losses on the non-covered portfolio totaled $93.8 million and $96.5 million at December 31, 2011 and 
September 30, 2011, respectively, and represented 3.34% of the non-covered loan balances at both of those dates. The allowance for credit losses 
as a percent of nonaccrual loans was 161% at both December 31, 2011 and September 30, 2011.  

        Noninterest income for the fourth quarter of 2011 totaled $8.3 million compared to $7.1 million for the third quarter of 2011. The $1.1 million 
increase was due to higher FDIC loss sharing income of $1.7 million stemming from a higher provision for credit losses on covered loans. FDIC loss 
sharing income also includes reductions of the FDIC loss sharing asset when the estimated amount of losses collectible from the FDIC decreases; 
this occurs when expected cash flows on covered loan pools improve during a reporting period causing the carrying value of the FDIC loss 
sharing asset to be reduced.

Includes (a) increases related to covered loan loss provisions and (b) decreases for loss share asset amortization and write-offs for covered loans resolved or 
expected to be resolved at amounts higher than their carrying value.  

        Noninterest expense decreased $5.1 million to $43.5 million during the fourth quarter of 2011 compared to $48.6 million for the third quarter of 
2011. This change was due mostly to lower covered OREO costs. Covered OREO costs decreased by $4.6 million due to lower write-downs of 
$7.7 million and lower gains on sales of $3.1 million. The fourth quarter included an $885,000 charge to compensation related to a staff reduction, 
which is expected to result in annual savings of approximately $2.4 million, and $600,000 in acquisition costs related to the Marquette Equipment 
Finance transaction; there were no similar items in the prior quarter. Other professional services declined $293,000 due mostly to internal audit 
transition costs recognized in the third quarter and a recovery of $368,000 in legal costs from an insurance claim in the fourth quarter. Occupancy 
costs declined $286,000 due mostly to third quarter leasing commissions and a lease buyout.  

        Noninterest expense includes amortization of time-based restricted stock, which is included in compensation, and intangible asset 
amortization. Amortization of restricted stock totaled $1.4 million and $2.1 million for the fourth and third quarters of 2011, respectively. Intangible 
asset amortization totaled $1.8 million and $2.0 million for the fourth and third quarters of 2011, respectively.  

Net Interest Income  

        Net interest income, which is our principal source of income, represents the difference between interest earned on interest-earning assets and

The tax-equivalent yield on investment securities was 3.22% for 2011; not applicable for 2010 and 2009.  

        Net interest income is affected by changes in both interest rates and the volume of average interest-earning assets and interest-bearing 
liabilities. The changes in the amount and mix of average interest-earning assets and interest-bearing liabilities are referred to as changes in 
"volume." The changes in the yields earned on average interest-earning assets and rates paid on average interest-bearing liabilities are referred to 
as changes in "rate." The change in interest income/expense attributable to volume reflects the change in volume multiplied by the prior year's rate 
and the change in interest income/expense attributable to rate reflects the change in rates multiplied by the prior year's volume. The changes in 
interest income and expense which are not attributable specifically to either volume or rate are allocated ratably between the two categories.

        Our net interest income and net interest margin are driven by the combination of our loan and securities volume, asset yield, high proportion 
of demand deposit balances to total deposits, and disciplined deposit pricing.  

        The $13.3 million growth in net interest income for 2011 compared to 2010 was due to a $5.0 million increase in interest income and an 
$8.3 million decline in interest expense. The increase in interest income was due mainly to purchases of investment securities and a higher yield on 
average loans, offset partially by lower average loans and a lower yield on average securities. The loan yield, earning asset yield and net interest 
margin are all affected by loans being placed on or removed from nonaccrual status and the acceleration of purchase discounts on covered loan 
pay-offs; the combination of these items increased interest income $9.5 million and positively impacted the net interest margin 19 basis points in 
2011. For 2010, these items increased interest income $4.1 million and increased the net

interest margin 8 basis points. Accelerated accretion of purchase discounts on covered loan payoffs positively impacted the net interest margin by 
18 basis points and 10 basis points for 2011 and 2010, respectively.  

        The decline in interest expense was due to a lower average rate on money market deposits, lower average time deposits and lower average 
borrowings as $260 million of FHLB advances were repaid in the first half of 2010 and another $50 million were repaid in December 2010. Our overall 
cost of average deposits was 0.45% for 2011 compared to 0.59% for 2010. Noninterest-bearing demand deposits averaged $1.6 billion, or 36% of 
total average deposits for 2011 compared to $1.4 billion, or 32% of total average deposits for 2010.  

        The net interest margin for 2011 was 5.26%, an increase of 24 basis points when compared to 2010. The increase was due to a higher yield on 
loans, lower costs for money market deposits and subordinated debentures, and a lower average balance of FHLB advances. This was offset 
partially by a shift in the mix of average interest-earning assets to lower yielding investment securities from higher yielding loans. Average interest-
earning assets increased $21.8 million due mostly to a $424.9 million increase in average investment securities while average loans decreased 
$313.3 million.  

2010 Compared to 2009  

        The $33.3 million growth in net interest income for 2010 compared to 2009 was due to a $20.4 million increase in interest income and a 
$12.9 million decline in interest expense. The increase in interest income was due to higher average balances of investment securities from the 
purchase of $627.9 million of government-sponsored entity pass through securities during 2010, the interest-earning assets from the Los Padres 
and Affinity acquisitions, and a higher average yield on loans. The impact from loans being placed on or removed from nonaccrual status and the 
acceleration of purchase discounts on covered loan pay-offs was a $4.1 million increase to interest income and an 8 basis point increase in the net 
interest margin for 2010. For 2009, these items reduced interest income $4.1 million and decreased the net interest margin 9 basis points.  

        The decline in interest expense was due mainly to lower rates paid on deposits and lower average borrowings. Our overall cost of average 
deposits was 0.59% for 2010 compared to 0.88% for 2009. Noninterest-bearing demand deposits averaged $1.2 billion, or 35% of total average 
deposits for 2009.  

        The net interest margin for 2010 was 5.02%, an increase of 23 basis points when compared to 2009. The increase is due mostly to a higher yield 
on average loans and lower funding costs, due principally to lower rates paid on deposits and lower average borrowings. Accelerated accretion of 
purchase discounts on covered loan payoffs positively impacted the net interest margin by 10 basis points for 2010; there was no impact for 2009.

        Provisions for credit losses are charged to earnings as and when needed for both on and off balance sheet credit exposures. We have a 
provision for credit losses on our non-covered loans and a provision for credit losses on our covered loans. The provision for credit losses on our 
non-covered loans is based on our allowance methodology and is an expense that, in our judgment, is required to maintain the adequacy of the 
allowance for loan losses and the reserve for unfunded loan commitments. Our allowance methodology reflects net charge-offs, the levels and 
trends of nonaccrual and classified loans, and the migration of loans into various risk classifications. The provision for credit losses on our 
covered loans reflects decreases in expected cash flows on covered loans compared to those previously estimated.  

        We made provisions for credit losses totaling $26.6 million during 2011, $212.5 million during 2010, and $159.9 million during 2009. The 2011 
provision for credit losses was comprised of a $10.5 million addition to the allowance for loan losses on the non-covered loan portfolio, a 
$13.3 million addition to the covered loan allowance for credit losses, and a $2.8 million addition to the reserve for unfunded loan commitments.  

        The 2010 provision for credit losses was comprised of a $179.0 million addition to the allowance for loan losses on the non-covered loan 
portfolio, a $33.5 million addition to the covered loan allowance for credit losses, and a $114,000 addition to the reserve for unfunded loan 
commitments. The 2010 provision for credit losses on non-covered loans includes $85.7 million related to $398.5 million of classified loans sold in 
2010.

        The 2009 provision for credit losses was composed of a $141.6 million addition to the allowance for loan losses on the non-covered loan 
portfolio, an $18.0 million addition to the covered loan allowance for credit losses and a $290,000 addition to the reserve for unfunded loan 
commitments.  

        Net charge-offs on non-covered loans decreased by $175.1 million to $23.8 million when compared to 2010. The net charge-offs for 2010 
included $144.6 million related to the sales of $398.5 million in classified loans.  

        The allowance for credit losses on the non-covered loan portfolio totaled $93.8 million, or 3.34% of non-covered loans, net of unearned 
income, at December 31, 2011. The allowance for credit losses on the non-covered loan portfolio totaled $104.3 million, or 3.30% of non-covered 
loans, net of unearned income, at December 31, 2010. Of these amounts, the allowance for loan losses totaled $85.3 million at December 31, 2011 
and $98.6 million at December 31, 2010.  

        Under the terms of our loss sharing agreements, the FDIC will absorb 80% of the losses on the covered loans. As a result, the effect on pre-tax 
earnings was 20% of the provision for covered loans as we recorded 80% of this provision as an offset in FDIC loss sharing income. The 
provisions for credit losses on covered loans for 2011, 2010 and 2009 were $13.3 million, $33.5 million and $18.0 million, respectively. The increase in 
the provision for 2010 compared to 2009 reflects the additional covered loans from the Los Padres acquisition.  

        Increased provisions for credit losses may be required in the future based on loan and unfunded commitment growth, the effect changes in 
economic conditions, such as inflation, unemployment, market interest rate levels, and real estate values may have on the ability of our borrowers 
to repay their loans, and other negative conditions specific to our borrowers' businesses. See "—Critical Accounting Policies," "—Financial 
Condition—Allowance for Credit Losses on Non-Covered Loans," "—Financial Condition—Allowance for Credit Losses on Covered Loans," and

Includes (a) increases related to covered loan loss provisions and (b) decreases for loss share asset amortization and write-offs for covered loans resolved or 
expected to be resolved at amounts higher than their carrying value.  

2011 Compared to 2010  

        Noninterest income declined by $11.8 million to $31.4 million during the year ended December 31, 2011 compared to the same period last year. 
This reduction was attributable to the $15.0 million decrease in FDIC loss sharing income, due mostly to the lower provision for credit losses on 
covered loans. In addition to including the FDIC's share of losses and recoveries on covered assets, FDIC loss sharing income also includes 
reductions of the FDIC loss sharing asset when the estimated amount of losses collectible from the FDIC decreases. This occurs when expected 
cash flows on covered loan pools improve during a reporting period causing the carrying value of the FDIC loss sharing asset to be reduced. 
Service charges on deposit accounts increased due primarily to the growth in service charges on checking accounts and account analysis fees. In 
2010 we recognized an $874,000 other-than-temporary impairment loss on one covered investment security due to deteriorating cash flows and 
significant delinquency of the underlying loan collateral. The 2010 impairment loss was offset partially by related FDIC loss sharing income of 
$699,000. There were no such impairments or impairment-related loss sharing income in 2011.  

2010 Compared to 2009  

        Noninterest income declined in 2010 to $43.2 million from the $105.9 million earned in 2009. The $62.7 million decrease was due mainly to the 
$67.0 million gain on the Affinity acquisition recorded in August 2009; there was no similar gain in 2010. The 2010 overall decline compared to 2009 
was offset partially by an increase of $6.5 million in FDIC loss sharing income to $22.8 million. The increase in FDIC loss sharing income for 2010 
was attributable mostly to the FDIC's share of the $15.5 million increase in the provision for credit losses on covered loans. Another factor 
contributing to the decline in noninterest income was an $874,000 other-than-temporary impairment loss recognized in 2010. This impairment loss 
was offset partially by related FDIC loss sharing income of $699,000. Service charges on deposit accounts decreased $447,000 due mostly to a 
decrease in NSF handling fees because fewer checks were drawn against accounts with insufficient funds. The decline in other income is attributed 
to the receipt of a death benefit in 2009; there were no such benefits received in 2010.

        Noninterest expense declined by $8.8 million to $180.0 million for 2011. This reduction was attributable to decreases in non-covered net OREO 
costs, insurance and assessments expense, other expense, intangible asset amortization, and compensation expense, offset partially by increases in 
covered OREO costs, other professional services, and occupancy expense. Non-covered OREO costs

declined $5.3 million due to lower write-downs of $7.2 million, offset by lower gains on sales of $1.8 million. Insurance and assessment costs 
decreased $2.5 million due to a reduction in FDIC deposit insurance costs. Other expense declined $2.3 million due mostly to $2.7 million in 
penalties for early repayment of $175 million in FHLB advances in 2010; there were no FHLB prepayment penalties in 2011. Intangible asset 
amortization decreased $1.2 million due mainly to $9.2 million of core deposit and customer relationship intangibles becoming fully amortized in 
2011. Compensation expense declined $683,000 due primarily to a decrease in amortization of restricted stock. Included in compensation expense 
for 2011 was an $885,000 charge in the fourth quarter for a staff reduction, which is expected to result in annual savings of $2.4 million. Covered 
OREO costs increased by $1.2 million due to higher write-downs, which were offset by higher gains on sales. The increase in other professional 
services was due to higher legal costs for ongoing credit work-outs. For acquisitions completed after January 1, 2009, acquisition related costs, 
such as legal, accounting valuation and other professional fees, necessary to effect a business combination, are charged to earnings in periods in 
which the costs are incurred. We incurred and charged to expense approximately $600,000 and $732,000 of such costs in 2011 and 2010, 
respectively. Occupancy costs grew $1.0 million due to lease renewal activity and the inclusion for a full year of occupancy costs related to the 
branches added in the Los Padres acquisition, which was completed in August 2010. Initially we acquired 14 branches, and through branch 
consolidations, ended 2011 with eight former Los Padres branches.  

        Noninterest expense includes (i) amortization of time-based restricted stock, which vests either in increments over a three to five year period or 
at the end of such period and is included in compensation expense and (ii) intangible asset amortization, which is related to customer deposit and 
customer relationship intangible assets. Amortization of restricted stock totaled $7.6 million and $8.5 million for the years ended December 31, 2011 
and 2010. Intangible asset amortization was $8.4 million and $9.6 million for 2011 and 2010.  

2010 Compared to 2009  

        Noninterest expense increased $9.6 million year-over-year to $188.8 million for 2010. The growth in most expense categories was due primarily 
to higher overhead costs related to the Affinity and Los Padres acquisitions. Compensation increased $9.3 million due to the acquisitions and 
severance costs. Excluding employees gained in the Los Padres acquisition, we reduced our workforce by approximately 5% and paid $1.0 million 
in severance at the end of the third quarter of 2010. Occupancy costs increased $1.3 million due mostly to the 10 branches added in the Affinity 
acquisition and 14 branches added in the Los Padres acquisition. Other professional services increased $1.5 million due mostly to higher legal 
costs related to loan workout activity and consulting fees for various strategic initiatives. For our successful acquisition activity, we incurred and 
charged to expense $732,000 and $600,000 of professional services fees which are separately categorized as acquisition costs. Other expense 
increased $3.5 million due mostly to a $1.2 million increase in loan-related costs, $2.7 million in penalties for early repayment of $175 million in FHLB 
advances in 2010, and lower reorganization charges of $1.2 million. There were no FHLB prepayment penalties in 2009. The elevated loan-related 
costs were attributed to ongoing workout efforts. The 2009 reorganization charges totaled $1.2 million and related to a first quarter staff reduction, 
premises costs for the closing of two banking offices in the second quarter, and additional rent for a discontinued acquired office. OREO costs 
declined $8.6 million due mostly to higher net gains on sales and lower write-downs and costs in 2010.  

        Amortization of restricted stock totaled $8.5 million and $8.2 million for the years ended December 31, 2010 and 2009. Intangible asset 
amortization was $9.6 million and $9.5 million for 2010 and 2009.

Income Taxes  

        Effective income tax rates were 42.1%, 43.0%, and 45.5% for the years ended December 31, 2011, 2010, and 2009, respectively. The difference in 
the effective tax rates between the annual periods relates mainly to the level of tax credits and tax deductions and the amount of tax exempt income 
recorded in each of the years. For further information on income taxes, see Note 14, Income Taxes, of the Notes to Consolidated Financial

Loans held for sale, consisting of SBA 504 and 7(a) loans, were transferred into the regular portfolio during the second quarter of 2008.  

Denominated in U.S. dollars and collateralized by assets located in the United States or guaranteed or insured by businesses located in the United States.  

        During 2011, gross non-covered loans declined $353.3 million due to repayments and resolution activities. The Bank continues to selectively 
generate loans and renew maturing loans that meet our credit quality and pricing standards and which will contribute positively to profitability and 
net interest margin.  

        During 2010, gross non-covered loans declined $547.9 million due primarily to $398.5 million in non-covered classified loans sold during the 
year. The decline was offset partially by the $234.1 million purchase of performing loans in July 2010.  

        The strategic decision to sell the non-covered classified loans was made specifically to reduce credit risk in order to strengthen the Bank's 
balance sheet and to be able to continue to participate in bidding on FDIC-assisted acquisitions. Such sales resulted in immediate reductions of 
non-covered classified loans and improved credit quality metrics as the loans sold included $128.1 million in nonaccrual loans and $148.8 million in 
performing restructured loans. The loans were sold for cash of $254.6 million and were completed on a servicing-released basis and without 
recourse to Pacific Western Bank. All of the loans sold were originated by Pacific Western Bank and none were covered loans acquired in our 
FDIC-assisted acquisitions. These sales resulted in a charge-off to the allowance for credit losses of $143.9 million, of which $58.2 million had been 
previously allocated to the loans sold through our allowance methodology and $85.7 million represented the market discount necessary for the 
loans to be sold to the buyer. The decisions to enter into these transactions were made shortly before the sale dates and after the immediately 
preceding reporting periods. Therefore, the loans were not accounted for as being held for sale prior to the transaction.

Covered Loans  

Los Padres Bank Acquisition  

        On August 20, 2010, we acquired certain assets of Los Padres Bank, including all loans, and assumed substantially all of its liabilities, 
including all deposits, from the FDIC in an FDIC-assisted acquisition, which we refer to as the Los Padres acquisition. We entered into a loss 
sharing agreement with the FDIC, whereby the FDIC agreed to cover a substantial portion of any future losses on acquired loans, with the 
exception of consumer loans, and other real estate owned. Under the terms of such loss sharing agreement, the FDIC is obligated to reimburse the 
Bank for 80% of losses with respect to the covered assets. The Bank will reimburse the FDIC for 80% of recoveries with respect to losses for which 
the FDIC paid the Bank 80% reimbursement under the loss sharing agreement. The loss sharing provisions for single family covered assets and 
commercial (non-single family) covered assets are in effect for 10 years and 5 years, respectively, from the acquisition date, and the loss recovery 
provisions are in effect for 10 years and 8 years, respectively, from the acquisition date.  

Affinity Bank Acquisition  

        On August 28, 2009, Pacific Western Bank acquired certain assets and liabilities of Affinity Bank from the FDIC in an FDIC-assisted 
transaction. We entered into a loss sharing agreement with the FDIC, whereby the FDIC agreed to cover a substantial portion of any future losses 
on acquired loans, other real estate owned and certain investment securities. Under the terms of such loss sharing agreement, the FDIC will absorb 
80% of losses and receive 80% of loss recoveries on the first $234 million of losses on covered assets and absorb 95% of losses and receive 95% 
of loss recoveries on covered assets exceeding $234 million. The loss sharing provisions are in effect for 5 years for commercial assets (non-
residential loans, OREO and certain securities) and 10 years for residential loans from the August 28, 2009 acquisition date. The loss recovery 
provisions are in effect for 8 years for commercial assets and 10 years for residential loans from the acquisition date.  

        We refer to the loans acquired in the Los Padres and Affinity acquisitions and subject to the loss sharing agreements as "covered loans." We 
refer to the acquired assets subject to the loss sharing agreements collectively as "covered assets."  

        At the acquisition dates, we estimated the fair values of the Los Padres and Affinity covered loans to be $436.3 million and $675.6 million, 
respectively. Fair value of acquired loans is determined using a discounted cash flow model based on assumptions about the amount and timing of 
principal and interest payments, estimated prepayments, estimated default rates, estimated loss severity in the event

of defaults, and current market rates. Estimated credit losses are included in the determination of fair value; therefore, an allowance for loan losses 
is not recorded on the acquisition date.

        We account for loans under ASC Subtopic 310-30, "Loans and Debt Securities Acquired with Deteriorated Credit Quality" ("acquired 
impaired loan accounting") when (i) we acquire loans deemed to be impaired when there is evidence of credit deterioration since the origination 
and it is probable at the date of acquisition that we would be unable to collect all contractually required payments and (ii) as a general policy 
election for non-impaired loans that we acquire in a distressed bank acquisition. We may refer to acquired loans accounted for under ASC 310-30 
as "acquired impaired loans." In connection with the Affinity acquisition, we applied acquired impaired loan accounting to all of the covered loans. 
In connection with the Los Padres acquisition, we applied acquired impaired loan accounting to all of the covered loans except the revolving credit 
agreements, mainly home equity loans and commercial asset-based lines of credit, where the borrower had revolving privileges; we accounted for 
such loans in accordance with accounting requirements for purchased non-impaired loans. GAAP excludes revolving credit agreements, such as 
home equity lines and credit card loans, from acquired impaired loan accounting requirements.  

        For acquired impaired loans, we (i) calculated the contractual amount and timing of undiscounted principal and interest payments (the 
"undiscounted contractual cash flows") and (ii) estimated the amount and timing of undiscounted expected principal and interest payments (the 
"undiscounted expected cash flows"). Under acquired impaired loan accounting, the difference between the undiscounted contractual cash flows 
and the undiscounted expected cash flows is the nonaccretable difference. The nonaccretable difference represents an estimate of the loss 
exposure of principal and interest related to the covered acquired impaired loan portfolios; such amount is subject to change over time based on 
the performance of such covered loans. The carrying value of covered acquired impaired

loans is reduced by payments received, both principal and interest, and increased by the portion of the accretable yield recognized as interest 
income.  

        The excess of undiscounted expected cash flows at acquisition over the initial fair value of acquired impaired loans is referred to as the 
"accretable yield" and is recorded as interest income over the estimated life of the loans using the effective yield method if the timing and amount 
of the future cash flows is reasonably estimable. The accretable yield changes over time due to both accretion and as actual and expected cash 
flows vary from the acquisition date estimated cash flows. The accretable yield is measured at each financial reporting date and represents the 
difference between the remaining undiscounted expected cash flows and the current carrying value of the loans. The remaining undiscounted 
expected cash flows are calculated at each financial reporting date based on information then currently available. Subsequent to acquisition, the 
Company aggregates loans into pools of loans with common credit risk characteristics such as loan type and risk rating. Increases in expected cash 
flows over those previously estimated increase the accretable yield and are recognized as interest income prospectively. Decreases in the amount 
and changes in the timing of expected cash flows compared to those previously estimated decrease the accretable yield and usually result in a 
provision for loan losses and the establishment of an allowance for loan losses.  

        Under acquired impaired loan accounting, purchased loans are generally considered accruing and performing loans as the loans accrete 
interest income over the estimated life of the loan when expected cash flows are reasonably estimable. Accordingly, acquired impaired loans that 
are contractually past due are still considered to be accruing and performing loans as long as there is an expectation that the estimated cash flows 
will be received. If the timing and amount of cash flows is not reasonably estimable, the loans may be classified as nonaccrual loans and interest 
income may be recognized on a cash basis or as a reduction of the principal amount outstanding.  

        The following table summarizes the changes in the carrying amount of covered acquired impaired loans and accretable yield on those loans for

        At December 31, 2011, the portion of the allowance allocated to individual portfolio segments included an amount for both imprecision and 
uncertainty to better reflect our view of risk. Nonetheless, the allowance for loan losses is available to absorb any losses without restriction. For 
further information on the allowance for loan losses, see Note 6, Loans, of the Notes to Consolidated Financial Statements contained in "Item 8. 
Financial Statements and Supplementary Data."

Excludes covered loans and covered OREO from the Los Padres and Affinity acquisitions.  

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

        During 2011, non-covered nonperforming assets declined by $13.1 million to $106.7 million at December 31, 2011, due mainly to a decrease of 
$35.9 million in nonaccrual loans, offset partially by an increase in other real estate owned of $22.8 million. The ratio of non-covered nonperforming 
assets to non-covered loans and non-covered OREO decreased to 3.73% at December 31, 2011 from 3.76% at December 31, 2010.  

Nonaccrual Loans  

        The $35.9 million decrease in non-covered nonaccrual loans during 2011 was attributable primarily to reductions, payoffs and returns to 
accrual status of $33.4 million, charge-offs of $24.5 million, and foreclosures of $34.9 million, offset partially by additions of $56.9 million.  

        Included in the non-covered nonaccrual loans at December 31, 2011 are $10.6 million of SBA related loans representing 18% of total non-
covered nonaccrual loans at that date. The SBA 504 loans are secured by first trust deeds on owner-occupied business real estate with loan-to-
value ratios of generally 50% or less at the time of origination. SBA 7(a) loans are secured by borrowers' real estate and/or business assets and are 
covered by an SBA guarantee of up to 85% of the loan amount. The SBA guaranteed portion on the 7(a) loans shown below is $7.1 million. At 
December 31, 2011, the SBA loan portfolio totaled $87.4 million and was composed of $58.4 million in SBA 504 loans and $29.0 million in SBA 7(a) 
loans.

        Non-covered performing restructured loans grew by $27.5 million during 2011, to $116.8 million at December 31, 2011. The change was 
attributable to additions of $58.8 million, offset partially by the removal of $16.7 million in loans from restructured loan status due to the 
performance of the loans in accordance with their modified terms and the transfers of performing restructured loans to nonaccrual status of 
$14.6 million. At December 31, 2011, we had $87.5 million in real estate mortgage loans, $24.5 million in real estate construction loans, $4.7 million in 
commercial loans, and $144,000 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 has remained on accrual status 
after the loan modifications due to the borrowers making payments before and after the restructurings. In these circumstances, generally, a 
borrower may have had a fixed rate loan that they continued to repay, but may be having cash flow difficulties. In an effort to work with certain 
borrowers, we have agreed to interest rate reductions to reflect the lower market interest rate environment and/or interest-only payments for a 
period of time. In these cases, we do not forgive principal or extend the maturity date as part of the loan modification. As a result of the current 
economic environment in our market areas, we anticipate loan restructurings to continue.  

Covered Nonperforming Assets  

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

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

        The negative trends throughout the Southern California economy have affected certain industries and collateral types more than others. Our 
real estate loan portfolio is predominantly commercial and as such does not expose us to higher risks generally associated with residential 
mortgage loans such as option ARM, interest-only or subprime mortgage loans. Our portfolio does include mortgage loans on commercial 
property. Commercial mortgage loan repayments typically do not rely on the sale of the underlying collateral and instead rely on the income 
producing potential of the collateral as the source  

79

of repayment. Ultimately, though, due to the loan amortization period being greater than the contractual loan term, the borrower may be required to 
refinance the loan, either with us or another lender, or sell the underlying collateral in order to pay off the loan.  

        At December 31, 2011, we had $205.5 million of commercial real estate mortgage loans maturing over the next 12 months. For any of these 
loans, in the event we provide a concession through a refinance or modification that we would not ordinarily consider in order to protect as much 
of our investment as possible, such loans may be considered troubled debt restructurings even though they were performing throughout their 
terms. The circumstances regarding any modification and a borrower's specific situation, such as their ability to obtain financing from another 
source at similar market terms, are evaluated on an individual basis to determine if a troubled debt restructuring has occurred. Higher levels of 
troubled debt restructurings may lead to increased classified assets and credit loss provisions.  

Investment Portfolio  

        Our investment activities are designed to assist in maximizing income consistent with quality and liquidity requirements, to supply collateral to 
secure public funds on deposit and lines of credit, and to provide a means for balancing market and credit risks through changing economic times. 
Our portfolio consists primarily of U.S. government agency obligations, obligations of government-sponsored entities, obligations of states and 
political subdivisions, private-label collateralized mortgage obligations ("CMOs"), corporate debt securities, and FHLB stock.  

        During 2011, 2010, and 2009, we made market purchases of $658.3 million, $627.9 million, and $227.5 million of investment securities available-
for-sale, respectively, utilizing our excess liquidity. During 2010, through the Los Padres acquisition, we obtained $44.3 million of investment 
securities, consisting of $10.7 million of FHLB stock and $33.6 million of investment securities available-for-sale. The securities available-for sale 
were comprised primarily of government and government-sponsored entity pass through securities. None of the acquired Los Padres investment 
securities are covered by an FDIC loss sharing agreement. During 2009, through the Affinity acquisition, we obtained $175.4 million of investment 
securities, consisting of $16.6 million of FHLB stock and $158.8 million of investment securities available-for-sale. The securities available-for-sale 
included $55.3 million of "private-label" CMOs which are covered by an FDIC loss sharing agreement. The remaining acquired Affinity securities 
available-for-sale were predominantly government and government-sponsored entity CMOs.

        We reviewed the securities that were in a continuous loss position less than 12 months and longer than 12 months at December 31, 2011, and 
concluded that their losses were a result of the level of market interest rates relative to the types of securities and not a result of the underlying 
issuers' abilities to repay. Accordingly, we determined that the securities were temporarily impaired. Additionally, we have no plans to sell these 
securities and believe that it is more likely than not we would not be required to sell these securities before recovery of their amortized cost. 
Therefore, we did not recognize the temporary impairment in the consolidated statements of earnings (loss).  

        During 2010, we determined that one covered private label collateralized mortgage obligation security was impaired due to deteriorating cash 
flows and significant delinquency of the underlying loan collateral and recorded an other-than-temporary impairment loss of $874,000 in the 
consolidated statement of earnings (loss). This loss was offset by FDIC loss sharing income of $699,000, which represented the FDIC's share of the 
loss.  

        At December 31, 2011, the Company had a $46.1 million investment in Federal Home Loan Bank of San Francisco ("FHLB") stock carried at 
cost. In January 2009, the FHLB announced that it suspended excess FHLB stock redemptions and dividend payments. Since this announcement, 
the FHLB has declared and paid cash dividends in 2010 and 2011, though at rates less than that paid in the past, and repurchased certain amounts 
of our excess stock. We evaluated the carrying value of our FHLB stock investment at December 31, 2011, and determined that it was not impaired. 
Our evaluation considered the long-term nature of the investment, the current financial and liquidity position of the FHLB, the actions being taken 
by the FHLB to address its regulatory situation, and our intent and ability to hold this investment for a period of time sufficient to recover our 
recorded investment.  

        During 2011, the Company redeemed $8.9 million of FHLB stock. During 2010, the Company obtained $10.7 million of FHLB stock in 
connection with the Los Padres acquisition and redeemed $6.0 million of FHLB stock. During 2009, the Company obtained $16.6 million of FHLB 
stock in connection with the Affinity acquisition.

        During 2011, deposits decreased by $72.2 million to $4.6 billion at December 31, 2011, due primarily to a reduction of $264.0 million in time 
deposits, which included a decrease of $42.2 million in brokered deposits. The decline in deposits was offset by a $191.7 million growth in core 
deposits. Brokered time deposits represent customer deposits that were subsequently participated with other FDIC insured financial institutions 
through the CDARS program as a means to provide FDIC deposit insurance coverage for the full amount of our customers' deposits.  

        We increased noninterest-bearing demand and money market deposits during 2011 due to a combination of new deposit relationships and 
increased deposits from our existing customers. We started 2011 with nearly 68,100 noninterest-bearing accounts and ended the year with 
approximately 62,000 noninterest-bearing accounts. Approximately 5,000 low-balance accounts were closed in 2011 when we implemented monthly 
service charges on previously free accounts. Competition for deposits among banks and financial institutions in our Southern California market 
area was robust in 2011 and is expected to continue through 2012. Our deposit gathering activities may be negatively impacted by two of our 
business practices. First, we generally price our deposits lower than our competitors. Second, since a good portion of our deposits are tied to 
lending relationships, the economic downturn in

Borrowings  

        The Bank has various lines of credit available. These include the ability to borrow funds from time to time on a long-term, short-term or 
overnight basis from the FHLB of San Francisco, the FRB or other financial institutions. The maximum amount that we could borrow under our 
credit lines with the FHLB at December 31, 2011 was $1.3 billion, of which $1.0 billion was available on that date. The maximum amount that we 
could borrow under our secured credit line with the FRB at December 31, 2011 was $347.4 million, all of which was available on that date. The FHLB 
lines are secured by a blanket lien on certain qualifying loans in our loan portfolio which are not pledged to the FRB and a portion of our available-
for-sale investment securities. The FRB line is secured by a blanket lien on certain qualifying loans that are not pledged to the FHLB.  

        At December 31, 2011, our borrowings included $225.0 million in term FHLB advances and $129.3 million of subordinated debentures. At 
December 31, 2010, our borrowings included $225.0 million in term FHLB advances and $129.6 million of subordinated debentures.

        On March 7 and 8, 2012, the Company redeemed $18 million of the subordinated debentures of Trust 1 and Trust CI and recognized a pre-tax 
gain of approximately $1.6 million. We redeemed these subordinated debentures to reduce our cost of funds, as these two instruments carried fixed 
interest rates of 11.0% and 10.6%.  

Capital Resources  

        We have access to the capital markets to raise funds, which is accomplished generally through the issuance of equity, both common and 
preferred stock, and the issuance of subordinated debentures. We

may use the proceeds to invest in our business through organic growth or other acquisitions. We also have the ability to invest in our Company 
through stock repurchase programs, which we have elected to do from time to time.  

        On December 22, 2009, we filed a registration statement with the SEC to offer to sell, from time to time, shares of common stock, preferred 
stock, and other equity linked securities for an aggregate initial offering price of up to $350 million. This registration statement was declared 
effective on January 8, 2010. Proceeds from any offering under this registration statement are anticipated to be used to fund future acquisitions of 
banks and financial institutions and for general corporate purposes.  

        On August 25, 2009, we sold in a direct placement to institutional investors 2.7 million shares of common stock for $50 million, or a per share 
price of $18.36, which was the closing price of PacWest's common stock on Monday, August 24, 2009. In addition to the issuance of the common 
shares, PacWest issued to each investor two warrants exercisable for common shares worth up to an additional $54 million in the aggregate with an 
exercise price of $20.20 per share, or 110% of the price per share at which the initial $50 million was sold. The Series A warrants had a six month 
term and originally expired on March 1, 2010; such warrants were exercised on March 1, 2010 for a total of $27.2 million in cash and we issued 
1,348,040 shares of common stock. The net proceeds from the warrant exercises totaled $26.6 million after expenses. The 1,361,657 Series B warrants 
issued in August 2009 with a strike price of $20.20 expired in August 2010 without being exercised. The common shares were sold and the warrants 
were issued under our $150 million shelf registration statement, which became effective in June 2009 but subsequently terminated upon the 
effectiveness declaration of our $350 million shelf registration statement on January 8, 2010.  

        On January 14, 2009, we issued in a private placement to CapGen Capital Group II LP 3,846,153 PacWest common shares at $26 per share for 
total cash consideration of approximately $100 million. CapGen Capital Group II LP has registered as a bank holding company and as a result of the 
investment it owned approximately 11% of PacWest outstanding common stock, excluding unvested restricted stock, as of December 31, 2011.  

        Bank regulatory agencies measure capital adequacy through standardized risk-based capital guidelines which compare different levels of 
capital (as defined by such guidelines) to risk-weighted assets and off-balance sheet obligations. Banks and bank holding companies considered 
to be "adequately capitalized" are required to maintain a minimum total risk-based capital ratio of 8% of which at least 4.0% must be Tier 1 capital. 
Banks and bank holding companies considered to be "well capitalized" must maintain a minimum leverage ratio of 5% and a minimum risk-based 
capital ratio of 10% of which at least 6.0% must be Tier 1 capital.  

        The following table presents regulatory capital requirements and our regulatory capital ratios at December 31, 2011. Regulatory capital 
requirements limit the amount of deferred tax assets that may be included when determining the amount of regulatory capital. Deferred tax asset 
amounts in excess of the calculated limit are deducted from regulatory capital. At December 31, 2011, such amount was $27.4 million for the 
Company and $21.9 million for the Bank. No assurance can be given that the regulatory capital deferred tax asset limitation will not increase in the 
future.

        As of December 31, 2011, we exceeded each of the capital requirements of the FRB and were deemed to be "well capitalized." In addition, as of 
December 31, 2011, Pacific Western exceeded the capital requirements to be "well capitalized." For further information on regulatory capital, see 
Note 19, Dividend Availability and Regulatory Matters, of the Notes to Consolidated Financial Statements contained in "Item 8. Financial 
Statements and Supplementary Data."  

        The Company issued subordinated debentures to trusts that were established by us or entities we have acquired, which, in turn, issued trust 
preferred securities, which totaled $123.0 million at December 31, 2011. The Company includes in Tier 1 capital an amount of trust preferred 
securities equal to no more than 25% of the sum of all core capital elements, which is generally defined as shareholders' equity less goodwill, net of 
any related deferred income tax liability. At December 31, 2011, the amount of trust preferred securities included in Tier I capital was $123.0 million. 
While our existing trust preferred securities are grandfathered under the Dodd-Frank Wall Street Reform and Consumer Protection Act that was 
enacted in July 2010, new issuances will not qualify as Tier 1 capital. See "—Borrowings" for information regarding the redemption in March 2012 
of certain of our subordinated debentures.  

        Interest payments on subordinated debentures made by the Company are considered dividend payments under FRB regulations. As such, 
notification to the FRB is required prior to our paying such interest during any period in which our quarterly net earnings are insufficient to fund 
the interest due. Should the FRB object to payment of interest on the subordinated debenture we would not be able to make the payments until 
approval is received or we no longer need to provide notice under applicable regulations.  

Liquidity  

        The goals of our liquidity management are to ensure the ability of the Company to meet its financial commitments when contractually due and 
to respond to other demands for funds such as the ability to meet the cash flow requirements of customers who may be either depositors wanting 
to withdraw funds or borrowers who may need assurance that sufficient funds will be available to meet their credit needs. We have an Executive 
Asset/Liability Management Committee, or Executive ALM Committee, which is comprised of members of senior management and 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 Federal Home Loan Bank of San Francisco 
("FHLB") and the Federal Reserve Bank of San Francisco ("FRB"), which we refer to as our secondary liquidity. In addition to its secured lines of 
credit, the Company also maintains unsecured lines of credit, subject to availability, of $45.0 million with correspondent banks for purchase of 
overnight funds.

        During 2011, the Company's primary liquidity increased $710 million. The increased liquidity levels are a function of current market 
conditions—loan demand has decreased while deposit balances have remained relatively unchanged. We expect to maintain higher levels of on-
balance sheet liquidity in 2012 compared to historical levels until we are able to effectively increase loan portfolio balances.  

        At December 31, 2011, the Company had pledged $3.0 billion of loans as collateral for the secured borrowing lines maintained with the FHLB 
and the FRB.  

        In addition to our primary liquidity, we generate liquidity from cash flow from our amortizing loan portfolio and from our large base of core 
customer deposits, defined as non-interest bearing demand, interest checking, savings and money market accounts. At December 31, 2011, such 
deposits totaled $3.6 billion and represented 79% of the Company's total deposits. These core deposits are normally less volatile, often with 
customer relationships tied to other products offered by the Company promoting long lasting relationships and stable funding sources. During 
2011, total core deposits increased $192 million, mainly in non-interest bearing demand deposits from our small to medium sized business customer 
base. Some of the growth in our core deposits is attributed to businesses having a tendency to maintain higher cash balances because of current 
economic conditions and low rate investment alternatives. Deposits from our customers may decline if interest rates increase significantly or if 
corporate customers move funds from the Company generally. In order to address the Company's liquidity risk as deposit balances may fluctuate, 
the Company maintains adequate levels of available liquidity.

        Our asset/liability policy establishes various liquidity guidelines for the Company. The policy includes guidelines for On-Balance Sheet 
Liquidity (a measurement of primary liquidity to total deposits), Coverage and Crisis Coverage Ratios (measurements of liquid assets to expected 
short-term liquidity required for the loan and deposit portfolios under normal and stressed conditions), Loan to Funding Ratio, Wholesale Funding 
Ratio, and other guidelines developed for measuring and maintaining liquidity. As of December 31, 2011, the Company was in compliance with all 
liquidity guidelines established in the ALCO policy.  

        We may use large denomination brokered time deposits, the availability of which is uncertain and subject to competitive market forces, for 
liquidity management purposes. At December 31, 2011, the Bank had none of these brokered deposits. In addition, we have $41.6 million of 
customer deposits that were subsequently participated with other FDIC insured financial institutions through the CDARS program as a means to 
provide FDIC deposit insurance coverage for the full amount of our participating customers' deposits.  

Holding Company Liquidity  

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

        Dividends paid by state banks, such as Pacific Western, are regulated by the DFI under its general supervisory authority as it relates to a 
bank's capital requirements. A state bank may declare a dividend without the approval of the DFI as long as the total dividends declared in a 
calendar year do not exceed either the retained earnings or the total of net profits for three previous fiscal years less any dividends paid during 
such period. During 2011, PacWest received $25.5 million in dividends from the Bank. For the foreseeable future, any dividends from the Bank to 
the Company require DFI approval. See also Note 19, Dividend Availability and Regulatory Matters, of the Notes to Consolidated Financial 
Statements contained in "Item 8. Financial Statements and Supplementary Data."  

        At December 31, 2011, the Company had, on a stand-alone basis, approximately $35.9 million in cash on deposit at the Bank. Management 
believes this amount of cash along with other sources of liquidity is sufficient to fund the Company's 2012 cash flow needs. See related discussion 
of liquidity sources at "—Capital Resources."

        Operating lease obligations, time deposits, and debt obligations are discussed in Note 9, Premises and Equipment, Net, Note 10, Deposits, and 
Note 11, Borrowings and Subordinated Debentures, of the Notes to Consolidated Financial Statements contained in "Item 8. Financial Statements 
and Supplementary Data." The other contractual obligations relate to our minimum liability associated with our data and item processing contract 
with a third-party provider. These contracts mature in 2012 but are expected to be renewed.  

        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 have in place various borrowing mechanisms for both short-term and long-term liquidity needs.  

Off-Balance Sheet Arrangements  

        Our obligations also include off-balance sheet arrangements consisting of loan-related commitments, of which only a portion are expected to 
be funded. At December 31, 2011, our loan-related commitments, including standby letters of credit, totaled $723.5 million. The commitments, which 
result in funded loans, increase our profitability through net interest income. We manage our overall liquidity taking into consideration funded and 
unfunded commitments as a percentage of our liquidity sources. Our liquidity sources, as described in "—Liquidity," have been and are expected 
to be sufficient to meet the cash requirements of our lending activities. For further information on loan commitments, see Note 12, Commitments 
and Contingencies, of the Notes to Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data."  

Recent Accounting Pronouncements  

        See Note 1, Nature of Operations and Summary of Significant Accounting Policies, of the Notes to Consolidated Financial Statements 
contained in "Item 8. Financial Statements and Supplementary Data" for information on recent accounting pronouncements and their impact, if any, 
on our consolidated financial statements.  

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK  

        Our market risk arises primarily from credit risk and interest rate risk inherent in our lending and financing activities. To manage our credit risk, 
we rely on adherence to our underwriting standards and loan policies, internal loan monitoring and periodic credit review as well as our allowance 
for credit losses methodology, all of which are administered by the Bank's credit administration department and overseen by the Company's Credit 
Risk Committee. To manage our exposure to changes in interest rates, we perform asset and liability management activities which are governed by 
guidelines

pre-established by our Executive ALM Committee, and approved by our Asset/Liability Management Committee of the Board of Directors, which 
we refer to as our Board ALCO. Our Executive ALM Committee monitors our compliance with our asset/liability policies. These policies focus on 
providing sufficient levels of net interest income while considering capital constraints and acceptable levels of interest rate exposure and liquidity.  

        Market risk sensitive instruments are generally defined as derivatives and other financial instruments, which include investment securities, 
loans, deposits, and borrowings. At December 31, 2011 and 2010, we had not used any derivatives to alter our interest rate risk profile or for any 
other reason. However, both the repricing characteristics of our fixed rate loans and floating rate loans, the significant percentage of noninterest-
bearing deposits compared to interest-earning assets, and the callable features in certain borrowings, may influence our interest rate risk profile. 
Our financial instruments include loans receivable, Federal funds sold, interest-earning deposits in financial institutions, Federal Home Loan Bank 
stock, investment securities, deposits, borrowings and subordinated debentures.  

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

        We evaluated the results of our net interest income simulation and market value of equity models prepared as of December 31, 2011, the results 
of which are presented below. Our net interest income simulation indicates that our balance sheet is liability sensitive as rising interest rates would 
result in a decline in our net interest margin. This profile is primarily a result of (a) the origination of fixed rate loans and variable rate loans with 
initial fixed rate terms due to customer preference and (b) declining floating rate construction loans. Our market value of equity model indicates an 
asset sensitive profile suggesting a sudden sustained increase in rates would result in an increase in our estimated market value of equity. This 
profile is a result of the assumed floors in the Company's offering rates, which are not expected to increase to the extent of the movement of market 
interest rates, and the significant value placed on the Company's noninterest-bearing deposits for purposes of this analysis.  

        The divergent profile between the net interest income simulation and market value of equity model is a result of the Company's significant 
level of noninterest-bearing deposits. Static balances of noninterest-bearing deposits do not impact the net interest income simulation, while at the 
same time the value of these deposits increases substantially in the market value of equity model when market rates are assumed to rise. In general, 
we view the net interest income model results as more relevant to the Company's current operating profile and manage our balance sheet based on 
this information.  

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 December 31, 2011. 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 and 
net interest income forecasted using a base market interest rate derived from the U.S. Treasury yield curve at December 31, 2011. In order to arrive 
at the base  

91 

Table of Contents 

case, we extend our balance sheet at December 31, 2011 one year and reprice any assets and liabilities that would contractually reprice or mature 
during that period using the products' pricing as of December 31, 2011. Based on such repricings, we calculate an estimated net interest income and 
net interest margin.  

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

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

        The following table presents as of December 31, 2011, 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.

2010. The decrease in forecasted net interest income was due primarily to lower assumed loan volume, partially offset by higher assumed securities 
volume.

        The net interest income simulation model prepared as of December 31, 2011 suggests our balance sheet is liability sensitive. Liability 
sensitivity indicates that in a rising interest rate environment, our net interest margin would decrease. Due to the historically low market interest 
rates as of December 31, 2011, the "down" scenarios are not considered meaningful and are excluded from the following discussion. The liability 
sensitive profile is due mostly to the mix of fixed rate loans to total loans in the loan portfolio relative to our amount of interest-bearing deposits 
that would reprice as interest rates change. Although $1.8 billion of the $3.5 billion of total loans in the portfolio have variable interest rate terms, 
only $708 million of those variable rate loans will reprice within twelve months. The remaining variable rate loans will behave as if they have fixed 
rates in the short run because of the effect of interest rate floors and hybrid ARM loan pricing structures of mini-perm commercial real estate loans, 
which generally contain initial fixed rate terms ranging from three to five years before becoming variable rate.  

        The following table presents as of December 31, 2010, 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.

        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 December 31, 2011.

        Our base case estimated market value of equity increased $122.9 million to $707.3 million at December 31, 2011 from $584.4 million at 
December 31, 2010. The increase in market value of equity was due primarily to (a) a $55.1 million increase in the fair value of our loan portfolio, 
which resulted from using a lower discount rate to value the loan portfolio in 2011, and (b) the $67.4 million increase in stockholders' equity during 
2011. The loan portfolio discount rate was adjusted down to reflect changes in market conditions and lower assumed loan floor rates on mini-perm 
commercial real estate loans.  

        The results of our market value of equity model indicate an asset sensitive interest rate risk profile in 2011 demonstrated by the increase in the 
market value of equity in the "up" interest rate scenarios compared to the "base case". Given the historically low market interest rates as of 
December 31, 2011, the "down" scenarios at December 31, 2011 are not considered meaningful and are excluded from the following discussion.  

        Our asset sensitive position as of December 31, 2011 is due primarily to the significant value placed on our noninterest-bearing deposits and 
the assumed floors in the discount rates used to value a portion of the loan portfolio. The discount rate used to value our loan portfolio is derived 
from the expected offering rate for each loan type with a similar term and credit risk profile. In a rising rate environment, management does not 
expect to increase our offering rates on certain loan products to the same extent as market rates until the fully indexed offering rate exceeds the 
current pricing floor, and in turn, our loans are not projected to lose significant value in the "up" 100 basis point and "up" 200 basis point 
scenarios. Conversely, the discount rates for our liabilities are expected to immediately change when market rates change. Therefore, our liabilities 
are expected to increase in value as rates rise thereby increasing the estimated market value of equity in the rising rate scenario.

        As part of the interest rate risk management process we use a gap analysis. A gap analysis provides information about the volume and 
repricing characteristics and relationship between the amounts of interest-sensitive assets and interest-bearing liabilities at a particular point in 
time. An effective interest rate strategy attempts to match the volume of interest sensitive assets and interest bearing liabilities repricing over 
different time intervals. The main focus of this interest rate management tool is the gap sensitivity identified as the cumulative one year gap.

        All amounts are reported at their contractual maturity or repricing periods, except for $46.1 million in FHLB stock which is shown as a longer-
term repricing investment because the timing of when FHLB stock may be redeemed is uncertain. This analysis makes certain assumptions as to 
interest rate sensitivity of savings and NOW accounts which have no stated maturity and have had very little price fluctuation in the past three 
years. Money market accounts are repriced at management's discretion and generally are more rate sensitive.  

        The preceding table indicates that we had a negative one-year cumulative gap of $738.4 million at December 31, 2011, a decline of $169.1 million 
from the $907.5 million negative one-year gap position at December 31, 2010. The decrease in the negative gap was attributable mostly to a decline 
in one-year liabilities of $325.7 million, reflecting decreases of $297.2 million and $28.5 million in one-year time deposits and interest-bearing 

  
 
 
  
    
 
 
 
 
 
 
 
 
  
 
 
 
   
 
   
 
   
 
   
 
   
 
   
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
   
 
   
 
   
 
   
 
   
 
   
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
 
  
 
  
 
  
 
  
 
  
 
  
 
 
  
 
  
 
   
 
   
 
   
 
   
 
   
 
   
 
 
 
  
 
  
 
 
  
 
  
checking, money market and savings, respectively. Partially offsetting this decline was a decline in one-year assets of $156.6 million, reflecting a 
decrease in one-year loans of $332.3 million and an increase in one-year cash and deposits in financial institutions of $177.0 million.

Table of Contents 

        This gap position suggests that we are liability sensitive and if rates were to increase, our net interest margin would most likely decrease. The 
ratio of interest-earning assets to interest-bearing liabilities maturing or repricing within one year at December 31, 2011 was 69.9%. This one-year 
gap position indicates that interest expense is likely to be affected to a greater extent than interest income for any changes in interest rates within 
one year from December 31, 2011.  

        Borrowings included two long-term FHLB advances totaling $225.0 million at December 31, 2011, with maturity dates of 2017 and 2018, which 
contain quarterly call options and are currently callable by the FHLB. While the FHLB may call the advances to be repaid for any reason, they are 
likely to be called if market interest rates, for borrowings of similar remaining term, are higher than the advances' stated rates on the call dates. If the 
advances are called by the FHLB, there is no prepayment penalty. Should our FHLB advances be called, we would evaluate the funding 
opportunities available at that time, including new secured borrowings from the FHLB at the then market rates. As borrowing rates are currently 
lower than our contract rates, we do not expect our secured FHLB borrowings to be called. We may repay the advances with a prepayment penalty 
at any time.  

        The gap table has inherent limitations and actual results may vary significantly from the results suggested by the gap table. The gap table is 
unable to incorporate certain balance sheet characteristics or factors. The gap table assumes a static balance sheet and, accordingly, looks at the 
repricing of existing assets and liabilities without consideration of new loans and deposits that reflect a more current interest rate environment. 
Unlike the net interest income simulation, however, the interest rate risk profile of certain deposit products and floating rate loans that have 
reached their floors cannot be captured effectively in a gap table. Although the table shows the amount of certain assets and liabilities scheduled 
to reprice in a given time frame, it does not reflect when or to what extent such repricings may actually occur. For example, interest-bearing 
checking, money market and savings deposits are shown to reprice in the first 3 months, but we may choose to reprice these deposits more slowly 
and incorporate only a portion of the movement in market rates based on market conditions at that time. Alternatively, a loan which has reached its 
floor may not reprice even though market interest rates change causing such loan to act like a fixed rate loan regardless of its scheduled repricing 
date. The gap table as presented cannot factor in the flexibility we believe we have in repricing deposits or the floors on our loans.  

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

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING  

        The management of PacWest Bancorp, including its consolidated subsidiaries, is responsible for establishing and maintaining adequate 
internal control over financial reporting. The Company's internal control system was designed to provide reasonable assurance to the Company's 
management and Board of Directors regarding the preparation and fair presentation of published financial statements in accordance with U.S. 
generally accepted accounting principles. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even 
those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.  

        Management maintains a comprehensive system of controls intended to ensure that transactions are executed in accordance with 
management's authorization, assets are safeguarded, and financial records are reliable. Management also takes steps to see that information and 
communication flows are effective and to monitor performance, including performance of internal control procedures.  

        As of December 31, 2011, PacWest Bancorp management assessed the effectiveness of the Company's internal control over financial reporting 
based on the framework established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the 
Treadway Commission. Based on this assessment, management has determined that the Company's internal control over financial reporting as of 
December 31, 2011, is effective.  

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements should they occur. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in 
conditions, or that the degree of compliance with the control procedures may deteriorate.  

        KPMG LLP, the independent registered public accounting firm that audited the Company's consolidated financial statements included in this 
Annual Report on Form 10-K, has issued a report on the effectiveness of the Company's internal control over financial reporting as of 
December 31, 2011. The report, which expresses an unqualified opinion on the effectiveness of the Company's internal control over financial 
reporting as of December 31, 2011, is included in this Item under the heading "Report of Independent Registered Public Accounting Firm."

The Board of Directors and Stockholders 
PacWest Bancorp:  

Report of Independent Registered Public Accounting Firm  

        We have audited the accompanying consolidated balance sheets of PacWest Bancorp and subsidiaries as of December 31, 2011 and 2010, and 
the related consolidated statements of earnings (loss), comprehensive income (loss), changes in stockholders' equity, and cash flows for each of 
the years in the three-year period ended December 31, 2011. We also have audited PacWest Bancorp's internal control over financial reporting as 
of December 31, 2011, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (COSO). PacWest Bancorp's management is responsible for these consolidated financial statements, 
for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial 
reporting, included in the accompanying management's report on internal control over financial reporting. Our responsibility is to express an 
opinion on these consolidated financial statements and an opinion on the Company's internal control over financial reporting based on our audits.  

        We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those 
standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material 
misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated 
financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing 
the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our 
audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk 
that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. 
Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a 
reasonable basis for our opinions.  

        A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of 
financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. 
A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in 
reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance 
that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting 
principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors 
of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of 
the company's assets that could have a material effect on the financial statements.  

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any 
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that 
the degree of compliance with the policies or procedures may deteriorate.  

        In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of PacWest 
Bancorp and subsidiaries as of December 31, 2011 and 2010, and the results of their operations and their cash flows for each of the years in the 
three-year period ended December 31, 2011, in conformity with U.S. generally accepted accounting principles. Also in our opinion, PacWest 
Bancorp maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011, based on criteria established 
in Internal Control—Integrated Framework issued by COSO.  

                                                                                             /s/ KPMG LLP

Notes to Consolidated Financial Statements  

NOTE 1—NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES  

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

        We have completed 22 acquisitions from May 2000 through December 31, 2011, including the merger whereby the former Rancho Santa Fe 
National Bank and First Community Bank of the Desert became wholly-owned subsidiaries of the Company in a pooling-of-interests transaction. 
All other acquisitions have been accounted for using the purchase method of accounting and, accordingly, their operating results have been 
included in the consolidated financial statements from their respective dates of acquisition. See Note 3, Acquisitions, and Note 4, Goodwill and 
Other Intangible Assets, for information about our Los Padres Bank and Affinity Bank acquisitions completed on August 20, 2010 and August 28, 
2009, respectively, and Note 23, Subsequent Events, for information about the January 3, 2012 acquisition of Marquette Equipment Finance, or 
MEF, an equipment leasing company located in Midvale, Utah.  

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

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

        Our operations, like those of other financial institutions operating in Southern California, are significantly influenced by economic conditions 
in Southern California, including local economies, the strength of the real estate market, and the fiscal and regulatory policies of the federal and 
state government and the regulatory authorities that govern financial institutions. With our operations in Arizona, Northern California, and the 
Pacific Northwest, we are also subject to the economic conditions affecting those markets. No individual or single group of related accounts is 
considered material in relation to our total assets or deposits of the Bank, or in relation to the overall business of the Company. However, 79% of 
our total gross non-covered and covered loan portfolio at December 31, 2011 consisted of real estate loans.

Notes to Consolidated Financial Statements (Continued)  

NOTE 1—NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)  

        There has been a slow-down in the real estate market due to negative economic trends and credit market disruption, the impact of which has 
been significant over the last several years. We have observed tighter credit underwriting and higher premiums on liquidity, both of which may 
continue to place downward pressure on real estate values. A continued downturn or any further deterioration in the real estate market could 
materially and adversely affect our business because a significant portion of our loans are secured by real estate. Our ability to recover on 
defaulted loans by selling the real estate collateral would then be diminished and we would be more likely to suffer losses on defaulted loans. 
Substantially all of our real property collateral is located in Southern California. Consequently, our results of operations and financial condition are 
dependent upon the general trends in the Southern California economies and, in particular, the residential and commercial real estate markets.  

        Real estate values could be affected by, among other things, a worsening of economic conditions, an increase in foreclosures, a decline in 
home sale volumes, an increase in interest rates, earthquakes and other natural disasters particular to California. Further, we may experience an 
increase in the number of borrowers who become delinquent, file for protection under bankruptcy laws or default on their loans or other 
obligations to us given a sustained weakness or weakening in business and economic conditions generally or specifically in the principal markets 
in which we do business. An increase in the number of delinquencies, bankruptcies or defaults could result in a higher level of nonperforming 
assets, net charge-offs and provision for credit losses.  

(a)    Basis of Presentation  

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

(b)    Use of Estimates  

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

(c)    Reclassifications  

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

NOTE 1—NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)  

(d)    Cash and Cash Equivalents  

        For purposes of the consolidated statements of cash flows, cash and cash equivalents consist of cash, due from banks, interest-earning 
deposits in financial institutions, and federal funds sold. Generally, federal funds are sold for one-day periods. Interest-earning assets in financial 
institutions represent cash held at the Federal Reserve Bank, the majority of which is immediately available.  

(e)    Investment Securities and Securities Available-for-Sale  

        We determine the classification of securities at the time of purchase. If we have the intent and the ability at the time of purchase to hold 
securities until maturity, they are classified as held-to-maturity. Investment securities held-to-maturity are stated at amortized cost. Securities to be 
held for indefinite periods of time, but not necessarily to be held-to-maturity or on a long-term basis, are classified as available-for-sale and carried 
at estimated fair value with unrealized gains or losses reported as a separate component of stockholders' equity in accumulated other 
comprehensive income, net of applicable income taxes. Securities available-for-sale include securities that management intends to use as part of its 
asset/liability management strategy and that may be sold in response to changes in interest rates, prepayment risk and other related factors. 
Securities are individually evaluated for appropriate classification when acquired; consequently, similar types of securities may be classified 
differently depending on factors existing at the time of purchase.  

        The carrying values of all securities are adjusted for amortization of premiums and accretion of discounts over the period to maturity of the 
related security using the interest method. Realized gains or losses on the sale of securities, if any, are determined using the amortized cost of the 
specific securities sold. If a decline in the fair value of a security below its amortized cost is judged by management to be other than temporary, the 
cost basis of the security is written down to its fair value and the amount of the write-down is included in operations.  

        Investments in Federal Home Loan Bank, or FHLB, stock are carried at cost and evaluated regularly for impairment. FHLB stock is expected to 
be redeemed at an amount not to exceed par and is a required investment based on measurements of the Bank's assets and/or borrowing levels.  

(f)    Loans Held for Sale and Servicing Assets  

        Loans held for sale include loans originated or purchased for resale. Loans originated or purchased for resale include the principal amount 
outstanding net of unearned income, and are carried at the lower of cost or fair value on an aggregate basis. A decline in the aggregate fair value of 
the loans below their aggregate carrying amount is recognized through a charge to earnings in the period of such decline. Unearned income on 
these loans is taken into earnings when the loans are sold. At December 31, 2011 and 2010, the Company had no loans held for sale.  

        Gains or losses resulting from sales of loans are recognized at the date of settlement and are based on the difference between the cash 
received and the carrying value of the related loans less related transaction costs. A transfer of financial assets in which control is surrendered is 
accounted for as a sale to the extent that consideration other than beneficial interests in the transferred assets is received in the exchange. Assets, 
liabilities, derivative financial instruments or other retained interests issued or obtained through the sale of financial assets are measured at 
estimated fair value, if practicable.

NOTE 1—NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)  

        The most common retained interest related to the loan sales is a servicing asset. Servicing assets are amortized in proportion to and over the 
period of estimated future net servicing income. The amortization of the servicing asset and the servicing income are included in noninterest 
income in the consolidated statement of earnings (loss). The fair value of the servicing assets is estimated by discounting the future cash flows 
using market-based discount rates and prepayment speeds. Our servicing asset is evaluated regularly for impairment. We stratify the servicing 
asset based on the original term to maturity and the year of origination of the underlying loans for purposes of measuring impairment. The risk is 
that loans prepay faster than anticipated and the fair value of the asset declines. If the fair value of the servicing asset is less than the amortized 
carrying value, the asset is considered impaired and an impairment charge will be taken against earnings.  

        At December 31, 2011 and 2010, the servicing asset totaled $1.3 million and $1.6 million, respectively, and related to the servicing of 
approximately $70.6 million and $82.5 million in SBA loans, respectively. The servicing asset is included in other assets on the consolidated 
balance sheets. All loans sold after December 31, 2008, were sold on a servicing released basis.  

(g)    Loans and Loan Fees  

        As a result of the Los Padres and Affinity acquisitions, we have a class of loans that are covered by loss sharing agreements with the FDIC 
which we refer to as "covered loans." When we refer to non-covered loans, which we may also refer to as legacy loans, we are referring to loans 
not covered by our loss sharing agreements with the FDIC.  

        Non-covered loans.    Non-covered loans are stated at the principal amount outstanding, net of any unearned discount or unamortized 
premium. Interest income is recorded on an accrual basis in accordance with the terms of the respective loan and includes prepayment penalties. 
Nonrefundable loan fees and related direct costs associated with the origination or purchase of loans are deferred and netted against outstanding 
loan balances. The net deferred fees or costs are recognized as an adjustment to interest income over the contractual life of the loans using the 
interest method or taken into income when the related loans are paid off or sold. The amortization of loan fees or costs is discontinued when a loan 
is placed on nonaccrual status.  

        Loans are considered delinquent when principal or interest payments are past due 30 days or more; delinquent loans may remain on accrual 
status between 30 days and 89 days past due. Loans on which the accrual of interest has been discontinued are designated as nonaccrual loans. 
The accrual of interest on loans is discontinued when principal or interest payments are past due 90 days or when, in the opinion of management, 
there is a reasonable doubt as to collectibility in the normal course of business. When loans are placed on nonaccrual status, all interest previously 
accrued but not collected is reversed against current period interest income. Income on nonaccrual loans is subsequently recognized only to the 
extent that cash is received and the loan's principal balance is deemed collectible. Loans are restored to accrual status when the loans become both 
well-secured and are in the process of collection.  

        Covered loans.    We refer to "covered loans" as those loans that we acquired in the Los Padres and Affinity acquisitions for which we will be 
reimbursed for a substantial portion of any future losses on them under the terms of the FDIC loss sharing agreements. We account for loans 
under Accounting

NOTE 1—NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)  

Standards Codification ("ASC") Subtopic 310-30, "Loans and Debt Securities Acquired with Deteriorated Credit Quality" ("acquired impaired 
loan accounting") when (i) we acquire loans deemed to be impaired when there is evidence of credit deterioration since their origination and it is 
probable at the date of acquisition that we would be unable to collect all contractually required payments and (ii) as a general policy election for 
non-impaired loans that we acquire in a distressed bank acquisition. We may refer to acquired loans accounted for under ASC 310-30 as "acquired 
impaired loans."  

        In connection with the Affinity acquisition, we applied acquired impaired loan accounting to all of the covered loans. In connection with the 
Los Padres acquisition, we applied acquired impaired loan accounting to all of the covered loans except for the acquired revolving credit 
agreements, mainly home equity loans and commercial asset-based lines of credit, where the borrower had revolving privileges; we accounted for 
such loans in accordance with accounting requirements for purchased non-impaired loans. GAAP excludes revolving credit agreements, such as 
home equity lines and credit card loans, from acquired impaired loan accounting requirements.  

        For acquired impaired loans, we (i) calculated the contractual amount and timing of undiscounted principal and interest payments (the 
"undiscounted contractual cash flows") and (ii) estimated the amount and timing of undiscounted expected principal and interest payments (the 
"undiscounted expected cash flows"). Under acquired impaired loan accounting, the difference between the undiscounted contractual cash flows 
and the undiscounted expected cash flows is the nonaccretable difference. The nonaccretable difference represents an estimate of the loss 
exposure of principal and interest related to the covered acquired impaired loan portfolios; such amount is subject to change over time based on 
the performance of such covered loans. The carrying value of covered acquired impaired loans is reduced by payments received, both principal 
and interest, and increased by the portion of the accretable yield recognized as interest income.  

        The excess of expected cash flows at acquisition over the initial fair value of acquired impaired loans is referred to as the "accretable yield" 
and is recorded as interest income over the estimated life of the loans using the effective yield method if the timing and amount of the future cash 
flows is reasonably estimable. If the timing of cash flows is uncertain, any cash payments will be recognized when received. Subsequent to 
acquisition, the Company aggregates loans into pools of loans with common credit risk characteristics such as loan type and risk rating. Increases 
in expected cash flows over those previously estimated increase the accretable yield and are recognized as interest income prospectively. 
Decreases in the amount and changes in the timing of expected cash flows compared to those previously estimated decrease the accretable yield 
and usually result in a provision for loan losses and the establishment of an allowance for loan losses. As the accretable yield increases or 
decreases from changes in cash flow expectations, the offset is a decrease or increase to the nonaccretable difference. The accretable yield is 
measured at each financial reporting date based on information then currently available and represents the difference between the remaining 
undiscounted expected cash flows and the current carrying value of the loans.  

        Under acquired impaired loan accounting, purchased loans are generally considered accruing and performing loans as the loans accrete 
interest income over the estimated life of the loan when expected cash flows are reasonably estimable. Accordingly, acquired impaired loans that 
are contractually past due are still considered to be accruing and performing loans as long as there is an expectation that the estimated cash flows 
will be received. If the timing and amount of cash flows is not reasonably

NOTE 1—NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)  

estimable, the loans may be classified as nonaccrual loans and interest income may be recognized on a cash basis or as a reduction of the principal 
amount outstanding.  

(h)    Impaired Loans and Allowances for Credit Losses  

        Impaired loans.    A loan is considered impaired when it is probable that we will be unable to collect all amounts due according to the 
contractual terms of the loan agreement. Impaired loans include loans on nonaccrual status and performing restructured loans. Income from loans 
on nonaccrual status is recognized to the extent cash is received and when the loan's principal balance is deemed collectible. Depending on a 
particular loan's circumstances, we measure impairment of a loan based upon either the present value of expected future cash flows discounted at 
the loan's effective interest rate, the loan's observable market price, or the fair value of the collateral less estimated costs to sell if the loan is 
collateral-dependent. The impairment amount on a collateral-dependent loan is charged-off to the allowance and the impairment amount on a loan 
that is not collateral-dependent is set up as a specific reserve.  

        Troubled Debt Restructurings.    A loan is classified as a troubled debt restructuring when we grant a concession to a borrower experiencing 
financial difficulties. These concessions may include a reduction of the interest rate, principal or accrued interest, extension of the maturity date or 
other actions intended to minimize potential losses. All loan modifications are evaluated on an individual basis to determine whether such 
modifications meet the criteria to be classified as a troubled debt restructuring under ASC Subtopic 310-40, "Troubled Debt Restructurings by 
Creditors." Loans restructured at a rate equal to or greater than that of a new loan with comparable risk at the time the loan is modified may be 
excluded from restructured loan disclosures in years subsequent to the restructuring if the loans are in compliance with their modified terms.  

        A loan that has been placed on nonaccrual status that is subsequently restructured will usually remain on nonaccrual status until the 
borrower is able to demonstrate repayment performance in compliance with the restructured terms for a sustained period, typically for six months. 
A restructured loan may return to accrual status sooner based on other significant events or mitigating circumstances. A loan that has not been 
placed on nonaccrual status may be restructured and such loan may remain on accrual status after such restructuring. In these circumstances, the 
borrower has made payments before and after the restructuring. Generally, this restructuring involves a reduction in the loan interest rate and/or a 
change to interest-only payments for a period of time. The restructured loan is considered impaired despite the accrual status and a specific 
reserve is calculated based on the present value of expected cash flows discounted at the loan's original effective interest rate.  

        Allowance for Credit Losses on Non-Covered Loans.    The allowance for credit losses on non-covered loans is the combination of the 
allowance for loan losses and the reserve for unfunded loan commitments. The allowance for credit losses on non-covered loans relates only to 
loans which are not subject to the loss sharing agreement with the FDIC. The allowance for loan losses is reported as a reduction of outstanding 
loan balances and the reserve for unfunded loan commitments is included within other liabilities on the consolidated balance sheets. Generally, as 
loans are funded, the amount of the commitment reserve applicable to such funded loans is transferred from the reserve for unfunded loan 
commitments to the allowance for loan losses based on our allowance methodology. The  

111

Notes to Consolidated Financial Statements (Continued)  

NOTE 1—NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)  

following discussion is for non-covered loans and the allowance for credit losses thereon. Refer to "Allowance for Credit Losses on Covered 
Loans" for the policy on covered loans.  

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

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

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

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

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

• 

Special Mention: Loans 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.  

112 

 
Table of Contents 

PACWEST BANCORP AND SUBSIDIARIES  

Notes to Consolidated Financial Statements (Continued)  

NOTE 1—NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)  

• 

• 

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

        In addition, we may refer to the loans classified as "substandard" and "doubtful" together as "criticized loans." For additional information on 
classified loans, see Note 6, Loans.  

        The allowance amounts for "pass" rated loans and those loans adversely classified, which are not reviewed individually, are determined using 
historical loss rates developed through migration analysis. The migration analysis is updated quarterly based on historic losses and movement of 
loans between ratings.  

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

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

        Management also believes that the reserve for unfunded loan commitments is adequate. In making this determination, management uses the 
same methodology for the reserve for unfunded loan commitments as for the allowance for loan losses and consider the same quantitative and 
qualitative factors, as well as off-balance sheet exposures and an estimate of the probability of drawdown of loan commitments correlated to their 
credit risk rating.  

        We recognize that the determination of the allowance for loan losses is sensitive to the assigned credit risk ratings and inherent loss rates at 
any given point in time. Therefore, we perform sensitivity analyses to provide insight regarding the impact adverse changes in credit risk ratings 
may have on our allowance for loan losses. The sensitivity analyses have inherent limitations and are based on various assumptions as of a point 
in time and, accordingly, it is not necessarily representative of the impact loan risk rating changes may have on the allowance for loan losses.

Notes to Consolidated Financial Statements (Continued)  

NOTE 1—NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)  

        Our federal and state banking regulators, as an integral part of their examination process, periodically review the Company's allowance for 
credit losses. Our regulators may require the Company to recognize additions to the allowance based on their judgments related to information 
available to them at the time of their examinations.  

        Allowance for Credit Losses on Covered Loans.    The covered loans are subject to our internal and external credit review. If deterioration in 
the expected cash flows results in a reserve requirement, a provision for credit losses is charged to earnings without regard to the FDIC loss 
sharing agreement. The portion of the estimated loss reimbursable from the FDIC will be recorded in FDIC loss sharing income and will increase the 
FDIC loss sharing asset. For acquired impaired loans, the allowance for loan losses is measured at the end of each financial reporting period based 
on expected cash flows. Decreases in the amount and changes in the timing of expected cash flows on the acquired impaired loans as of the 
financial reporting date compared to those previously estimated are usually recognized by recording a provision for credit losses on such covered 
loans. Conversely, improvements in the amount and timing of expected cash flows on such loans result in a reduction of the provision for credit 
losses or a prospective increase in the accretable yield and a reduction in the FDIC loss sharing asset via a charge to FDIC loss sharing expense.  

        Acquired loans not accounted for as impaired loans are subject to our allowance for credit losses methodology. Although we estimate the 
required allowance for credit losses similar to the methodology used for non-covered loans, we record a provision for such loan losses only when 
the reserve requirement exceeds any remaining credit discount on these covered loans.  

(i)    FDIC Loss Sharing Asset  

        The FDIC loss sharing asset was measured at estimated fair value on the Los Padres and Affinity acquisition dates using expected future cash 
flows from the FDIC and a discount rate based on a long-term risk-free interest rate plus a premium. Since the FDIC loss sharing asset was initially 
recorded at estimated fair value using a discount rate, a portion of the discount is recognized as FDIC loss sharing income in each reporting period.  

        Under the terms of the Los Padres loss sharing agreement, the FDIC is obligated to reimburse the Bank for 80% of losses with respect to the 
covered assets. The Bank will reimburse the FDIC for 80% of recoveries with respect to losses for which the FDIC paid the Bank 80% 
reimbursement under the loss sharing agreement. The Los Padres loss sharing provisions expire in the third quarters of 2015 and 2020 for non-
single family and single family covered assets, respectively, while the related loss recovery provisions expire in the third quarters of 2018 and 2020, 
respectively. Under the terms of the Affinity loss sharing agreement, the FDIC will (a) absorb 80% of losses and receive 80% of loss recoveries on 
the first $234 million of losses on covered assets and (b) absorb 95% of losses and receive 95% of loss recoveries on covered assets exceeding 
$234 million. The Affinity loss sharing provisions expire in the third quarters of 2014 and 2019 for non-single family covered assets and single 
family covered assets, respectively, while the related loss recovery provisions expire in the third quarters of 2017 and 2019, respectively.  

        An increase in the expected amount of losses on the covered assets will increase the FDIC loss sharing asset; such increase is recognized 
through a credit to FDIC loss sharing income. Recoveries on previous losses paid to us by the FDIC reduce the FDIC loss sharing asset by a 
charge to FDIC loss

sharing expense. In addition, decreases in the expected amount of losses on covered assets will decrease the amount of funds expected to be 
collected from the FDIC and will therefore reduce the FDIC loss sharing asset. These decreases are recognized as a charge to FDIC loss sharing 
expense as the related loss sharing asset is amortized over its estimated remaining life.  

(j)    Land, Premises and Equipment  

        Premises and equipment are stated at cost less accumulated depreciation and amortization. Land is not depreciated. Depreciation and 
amortization is charged to noninterest expense using the straight-line method over the estimated useful lives of the assets. The estimated useful 
lives of furniture, fixtures and equipment range from 3 to 10 years and for buildings up to 35 years. Leasehold improvements are amortized over 
their estimated useful lives, or the life of the lease, whichever is shorter.  

(k)    Other Real Estate Owned  

        Non-covered OREO.    Other real estate owned, or OREO, is initially recorded at the estimated fair value of the property, based on current 
independent appraisals obtained at the time of acquisition, less estimated costs to sell, including senior obligations such as delinquent property 
taxes. The excess of the recorded loan balance over the estimated fair value of the property at the time of acquisition less estimated costs to sell is 
charged to the allowance for loan losses. Any subsequent write-downs are charged to noninterest expense and recognized through an OREO 
valuation allowance. Subsequent increases in the fair value of the asset less selling costs reduce the OREO valuation allowance, but not below 
zero, and are credited to noninterest expense. Gains and losses on the sale of foreclosed properties and operating expenses of such assets are also 
included in noninterest expense.  

        Covered OREO.    Covered OREO was initially recorded at its estimated fair value on the acquisition date based on independent appraisals 
less estimated selling costs. Any subsequent write-downs due to declines in fair value are charged to noninterest expense with a partial offset to 
FDIC loss sharing income for the loss reimbursement under the FDIC loss sharing agreement. Any recoveries of previous write-downs are credited 
to noninterest expense with a corresponding charge to FDIC loss sharing income, net for the portion of the recovery that is due to the FDIC.  

(l)    Income Taxes  

        Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax 
consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax 
bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to 
taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on 
deferred tax assets and liabilities is recognized in earnings in the period that includes the enactment date. Any interest or penalties assessed by the 
taxing authorities is classified in the financial statements as income tax expense. Deferred tax assets are included in other assets on the 
consolidated balance sheets.

PACWEST BANCORP AND SUBSIDIARIES  

Notes to Consolidated Financial Statements (Continued)  

NOTE 1—NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)  

        On a quarterly basis, the Company evaluates its deferred tax assets to assess whether they are expected to be realized in the future. This 
determination is based on currently available facts and circumstances, including our current and projected future tax position, the historical level of 
our taxable income, and estimates of our future taxable income. In most cases, the realization of deferred tax assets is based on our future 
profitability. To the extent our deferred tax assets are no longer considered more likely than not to be realized, we could be required to record a 
valuation allowance on our deferred tax assets by charging earnings.  

(m)    Goodwill and Other Intangible Assets  

        Goodwill arises from business combinations and represents the excess of the purchase price over the fair value of the net assets and other 
identifiable intangible assets acquired. Goodwill and other intangible assets deemed to have indefinite lives generated from purchase business 
combinations are not subject to amortization and are instead assessed for impairment no less than annually. Impairment exists when the carrying 
value of the goodwill exceeds its implied fair value. Impairment charges are included in noninterest expense in the financial statements.  

        Intangible assets with estimable useful lives are amortized over such useful lives to their estimated residual values. Core deposit intangible 
assets, which we refer to as CDI, and customer relationship intangible assets, which we refer to as CRI, are recognized apart from goodwill at the 
time of acquisition based on market valuations prepared by independent third parties. In preparing such valuations, the third parties consider 
variables such as deposit servicing costs, attrition rates, and market discount rates. CDI assets are amortized to expense over their useful lives, 
which we have estimated to range from 7 to 10 years. CRI assets are amortized to expense over their useful lives, which we have estimated to range 
from 4 to 5 years. Both CDI and CRI are reviewed for impairment quarterly or earlier if events or changes in circumstances indicate that their 
carrying values may not be recoverable. If the recoverable amount of either CDI or CRI is determined to be less than its carrying value, we would 
then measure the amount of impairment based on an estimate of the intangible asset's fair value at that time. If the fair value is below the carrying 
value, the intangible asset is reduced to such fair value and the impairment is recognized as noninterest expense in the financial statements.  

(n)    Stock Incentive Plan  

        Compensation expense related to awards of restricted stock 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. The vesting of performance-based restricted stock awards and recognition of 
related compensation expense may occur over a shorter vesting period if financial performance targets are achieved earlier than anticipated. 
Amortization of unvested performance-based restricted stock is suspended when it becomes less than probable that the performance targets will 
be met. Amortization of unvested performance-based restricted stock is discontinued and previous amortization amounts are credited to earnings 
when it becomes improbable that performance targets will be met. When and if it becomes probable in the future that the performance target will be 
met a catch up adjustment is made and amortization begins.  

        Unvested restricted stock participates with common stock in any dividends declared and paid. Dividends paid on unvested restricted stock 
awards expected to vest and the related tax benefits are

NOTE 1—NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)  

included as a net reduction to stockholders' equity. Dividends paid on unvested restricted stock not expected to vest are charged to compensation 
expense.  

(o)    Business Segments  

        We have determined that we have one reportable business segment, banking operations.  

(p)    Comprehensive Income  

        Comprehensive income consists of net earnings and net unrealized gains (losses) on securities available-for-sale, net and is presented in the 
consolidated statements of comprehensive income.  

(q)    Earnings Per Share  

        In accordance with ASC Topic 260, "Earnings Per Share," all outstanding unvested share-based payment awards that contain rights to 
nonforfeitable dividends are considered participating securities and are included in the two-class method of determining basic and diluted earnings 
per share. All of our unvested restricted stock participates with our common stockholders in dividends. Accordingly, earnings allocated to 
unvested restricted stock are deducted from net earnings to determine that amount of earnings available to common stockholders. In the two-class 
method, the amount of our earnings available to common stockholders is divided by the weighted average shares outstanding, excluding any 
unvested restricted stock, for both the basic and diluted earnings per share.  

(r)    Business Combinations  

        Business combinations are accounted for under the acquisition method of accounting in accordance with ASC Topic 805, "Business 
Combinations." Under the acquisition method the acquiring entity in a business combination recognizes 100 percent of the acquired assets and 
assumed liabilities, regardless of the percentage owned, at their estimated fair values as of the date of acquisition. Any excess of the purchase 
price over the fair value of net assets and other identifiable intangible assets acquired is recorded as goodwill. To the extent the fair value of net 
assets acquired, including other identifiable assets, exceeds the purchase price, a bargain purchase gain is recognized. Assets acquired and 
liabilities assumed from contingencies must also be recognized at fair value, if the fair value can be determined during the measurement period. 
Results of operations of an acquired business are included in the statement of earnings from the date of acquisition. Acquisition-related costs, 
including conversion and restructuring charges, are expensed as incurred. We adopted this guidance as of January 1, 2009 and applied it to the 
Los Padres and Affinity acquisitions.  

(s)    Recently Issued Accounting Standards  

        In May 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2011-04, "Fair Value 
Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs." 
ASU 2011-04 was issued concurrently with IFRS 13, "Fair Value Measurements," to provide largely identical guidance about fair value 
measurement and disclosure requirements. ASU 2011-04 does not extend the use of fair value but, rather, provides guidance about how fair value 
should be applied where it already is required or permitted under U.S. GAAP or International Financial Reporting Standards (IFRSs). For 
U.S. GAAP,  

117 

 
Table of Contents 

PACWEST BANCORP AND SUBSIDIARIES  

Notes to Consolidated Financial Statements (Continued)  

NOTE 1—NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)  

most of the changes are clarifications of existing guidance or wording changes to align with IFRS 13. ASU 2011-04 is effective prospectively for 
interim and annual periods beginning after December 15, 2011. Early adoption is not permitted. In the period of adoption, a reporting entity will be 
required to disclose a change, if any, in valuation technique and related inputs that result from applying ASU 2011-04 and to quantify the total 
effect, if practicable. We have not as yet determined what effect, if any, adoption of ASU 2011-04 will have on our financial statements and related 
disclosures.  

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

        In September 2011, the FASB issued ASU 2011-08, "Intangibles—Goodwill and Other (Topic 350): Testing Goodwill for Impairment." Under 
ASU 2011-08, an entity is permitted to make a qualitative assessment of whether it is more likely than not that a reporting unit's fair value is less 
than its carrying amount before applying the two-step goodwill impairment test. If an entity concludes it is not more likely than not that the fair 
value of a reporting unit is less than its carrying amount, it need not perform the two-step impairment test. ASU 2011-08 is effective for annual and 
interim goodwill impairment tests performed in fiscal years beginning after December 15, 2011. Early adoption is permitted. We do not believe 
adoption of this standard will have any material effect on our financial statements.  

        In December 2011, the FASB issued ASU 2011-11, "Disclosures about Offsetting Assets and Liabilities." ASU 2011-11 requires disclosures 
about offsetting and related arrangements to allow investors to better compare financial statements issued under U.S. GAAP with financial 
statements prepared under International Financial Reporting Standards ("IFRS"). ASU 2011-11 is effective for annual periods beginning January 1, 
2013, and interim periods within those annual periods. Retrospective application is required. Adoption of this standard will not have a material 
effect on our financial statements.  

NOTE 2—RESTRICTED CASH BALANCES  

        The Company is required to maintain reserve balances with the Federal Reserve Bank, or FRB. Such reserve requirements are based on a 
percentage of deposit liabilities and may be satisfied by cash on hand. The average reserves required to be held at the FRB for the years ended 
December 31, 2011 and 2010 were $2.2 million and $1.2 million.

        On August 20, 2010, Pacific Western acquired certain assets of Los Padres Bank, including all loans, and assumed substantially all of its 
liabilities, including all deposits, from the Federal Deposit Insurance Corporation ("FDIC") in an FDIC-assisted acquisition, which we refer to as the 
Los Padres acquisition. We entered into a loss sharing agreement with the FDIC, whereby the FDIC agreed to cover a substantial portion of any 
future losses on acquired OREO and acquired loans, with the

exception of acquired consumer loans. We refer to the acquired assets subject to the loss sharing agreement collectively as "covered assets." 
Under the terms of such loss sharing agreement, the FDIC is obligated to reimburse the Bank for 80% of losses with respect to the covered assets. 
The Bank will reimburse the FDIC for 80% of recoveries with respect to losses for which the FDIC paid the Bank 80% reimbursement under the loss 
sharing agreement. The loss sharing provisions for single family covered assets and commercial (non-single family) covered assets are in effect for 
10 years and 5 years, respectively, from the August 20, 2010 acquisition date, and the loss recovery provisions are in effect for 10 years and 
8 years, respectively, from the acquisition date. Through December 31, 2011, gross losses for Los Padres covered assets totaled $47.1 million.  

        Los Padres was a federally chartered savings bank headquartered in Solvang, California that operated 14 branches, including 11 branches in 
California (three in Ventura County, four in Santa Barbara County, and four in San Luis Obispo County) and three branches in Arizona (Maricopa 
County). After office consolidations during 2011, we are operating eight of the former Los Padres branch offices, all of which are located in 
California. We made this acquisition to expand our presence in the Central Coast of California.  

        The assets acquired and liabilities assumed have 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 August 20, 2010 acquisition date. The application of the 
acquisition method of accounting resulted in goodwill of $47.3 million. Such goodwill included $9.5 million related to the FDIC's settlement 
accounting for a wholly-owned subsidiary of Los Padres. We disagreed with the FDIC's accounting for this item. During 2011, we resolved this 
matter with the FDIC for a cash payment of $7.6 million; goodwill was reduced by the same amount.  

Federally Assisted Acquisition of Affinity Bank  

        On August 28, 2009, Pacific Western acquired certain assets and assumed certain liabilities of Affinity Bank from the FDIC in an FDIC-assisted 
acquisition. We entered into a loss sharing agreement with the FDIC, whereby the FDIC agreed to cover a substantial portion of any future losses 
on acquired loans, other real estate owned and certain investment securities. We refer to the acquired assets subject to the loss sharing agreement 
collectively as "covered assets." Under the terms of such loss sharing agreement, the FDIC will absorb 80% of losses and receive 80% of loss 
recoveries on the first $234 million of losses on covered assets and absorb 95% of losses and receive 95% of loss recoveries on covered assets 
exceeding $234 million. The loss sharing provisions are in effect for 5 years for commercial assets (non-residential loans, OREO and certain 
securities) and 10 years for residential loans from the August 28, 2009 acquisition date. The loss recovery provisions are in effect for 8 years for 
commercial assets and 10 years for residential loans from the acquisition date. Affinity was a full service commercial bank headquartered in 
Ventura, California that operated 10 branch locations in California. We made this acquisition to expand our presence in California. Through 
December 31, 2011, gross losses for Affinity covered assets totaled $144.6 million.  

        The assets acquired and liabilities assumed have 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 August 28, 2009 acquisition date. The application of the 
acquisition method of accounting resulted in a net after-tax gain of $38.9 million ($67.0 million before tax).

PACWEST BANCORP AND SUBSIDIARIES  

Notes to Consolidated Financial Statements (Continued)  

        All of the acquisitions consummated after December 31, 2000 were completed using the acquisition method of accounting. For those 
acquisitions completed prior to January 1, 2009, we recorded the estimated merger-related charges associated with each acquisition as a liability at 
closing when the related purchase price was allocated. For each acquisition, we developed an integration plan for the Company that addressed, 
among other things, requirements for staffing, systems platforms, branch locations and other facilities. The remaining merger-related liability 
totaled $922,000 at December 31, 2011 and represented the estimated lease payments, net of estimated sublease income, for the remaining life of 
leases for abandoned space. For acquisitions completed after January 1, 2009, acquisition-related costs, such as legal, accounting, valuation and 
other professional fees, necessary to effect a business combination, are charged to earnings in the periods in which the costs are incurred. We 
incurred and charged to expense approximately $600,000, $732,000 and $600,000 of such costs in 2011, 2010 and 2009, respectively.  

Unaudited Pro Forma Results of Operations  

        The following table presents our unaudited pro forma results of operations for the periods presented as if the Los Padres acquisition had been 
completed on January 1, 2009 and the Affinity acquisition had been completed on January 1, 2008. The unaudited pro forma results of operations 
include the historical accounts of the Company and Affinity and pro forma adjustments as may be required, including the amortization of 
intangibles with definite lives and the amortization or accretion of any premiums or discounts arising from fair value adjustments for assets 
acquired and liabilities assumed. The unaudited pro forma information is intended for informational purposes only and is not necessarily indicative 
of our future operating results or operating results that would have occurred had the Los Padres acquisition been completed at the beginning of 
2009 and the Affinity acquisition completed at the beginning of 2008. No assumptions have been applied to the pro forma results of operations 
regarding possible revenue enhancements, expense efficiencies or asset dispositions.

        Our intangible assets with definite lives are core deposit and customer relationship intangibles. These intangibles are amortized over their 
respective estimated useful lives to their estimated residual values and reviewed for impairment at least quarterly. The amortization expense 
represents the estimated decline in the value of the underlying deposits or loan customers acquired. As of December 31, 2011, all of our customer 
relationship intangible assets had been fully amortized. The weighted average amortization period remaining for our core deposit intangibles is 
2.4 years. The estimated aggregate amortization expense related to these intangible assets for each of the next five years is $6.1 million, $4.5 million, 
$2.9 million, $2.7 million and $1.2 million.

        During 2011, 2010, and 2009, we made market purchases of $658.3 million, $627.9 million, and $227.5 million of investment securities available-
for-sale, respectively, utilizing our excess liquidity. During 2010, through the Los Padres acquisition, we obtained $44.3 million of investment 
securities, including $10.7 million of FHLB stock and $33.6 million of securities available-for-sale, consisting primarily of government and 
government-sponsored entity pass through securities and none of which

are covered by an FDIC loss sharing agreement. During 2009, through the Affinity acquisition, we obtained $175.4 million of investment securities, 
including $16.6 million of FHLB stock and $158.8 million of securities available-for-sale. The acquired Affinity securities included $55.3 million of 
"private-label" collateralized mortgage obligations ("CMOs") which are covered by an FDIC loss sharing agreement; the remaining securities were 
predominantly government and government-sponsored entity CMOs.  

        At December 31, 2011, the fair value of debt securities and mortgage-backed securities issued by the Federal National Mortgage Association 
("Fannie Mae") and the Federal Home Loan Mortgage Corporation ("Freddie Mac") was approximately $1.1 billion. We do not own any equity 
securities issued by Fannie Mae or Freddie Mac. There were no sales of securities in 2011, 2010 and 2009. As of December 31, 2011 and 2010, 
securities available-for-sale with a carrying value of $69.6 million and $140.7 million, respectively, were pledged as security for borrowings, public 
deposits and other purposes as required by various statutes and agreements.  

        Market valuations of our investment securities are provided by an independent third party. The fair values are determined by using several 
sources for valuing fixed income securities. Their techniques include pricing models that vary based on the type of asset being valued and 
incorporate available trade, bid and other market information. In accordance with the hierarchy established in ASC Topic 820, "Fair Value 
Measurement," the market valuation sources include observable market inputs for the majority of our securities and are therefore considered 
Level 2 inputs for purposes of determining the fair values. The valuation techniques for the covered private label CMOs are considered Level 3. 
See Note 13, Fair Value Measurements, for information on fair value measurements and methodology.  

        The following tables present, for those securities that were in a gross unrealized loss position, the carrying values, which are the estimated fair 
values, and the gross unrealized losses on securities by length of time the securities were in an unrealized loss position at the dates indicated:

        We reviewed the securities that were in a continuous loss position less than 12 months and longer than 12 months at December 31, 2011, and 
concluded that their losses were a result of the level of market interest rates relative to the types of securities and not a result of the underlying 
issuers' abilities to repay. Accordingly, we determined that the securities were temporarily impaired. Additionally, we have no plans to sell these 
securities and believe that it is more likely than not we would not be required to sell these securities before recovery of their amortized cost. 
Therefore, we did not recognize the temporary impairment in the consolidated statements of earnings.  

        During 2010, we determined that one covered private label collateralized mortgage obligation security was impaired due to deteriorating cash 
flows and significant delinquency of the underlying loan collateral and recorded an other-than-temporary impairment loss of $874,000 in the 
consolidated statement of loss. This loss was offset by FDIC loss sharing income of $699,000, which represented the FDIC's 80% share of the loss.  

        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.  

        The contractual maturity distribution of our securities available-for-sale portfolio based on amortized cost and carrying value is shown as of 
the date below:

NOTE 5—INVESTMENT SECURITIES (Continued)  

FHLB Stock  

        At December 31, 2011, the Company had a $46.1 million investment in Federal Home Loan Bank of San Francisco ("FHLB") stock carried at 
cost. In January 2009, the FHLB announced that it suspended excess FHLB stock redemptions and dividend payments. Since this announcement, 
the FHLB has declared and paid cash dividends in 2010 and 2011, though at rates less than those paid in the past, and repurchased certain 
amounts of our excess stock at the carrying value. We evaluated the carrying value of our FHLB stock investment at December 31, 2011, and 
determined that it was not impaired. Our evaluation considered the long-term nature of the investment, the current financial and liquidity position 
of the FHLB, the actions being taken by the FHLB to address its regulatory situation, repurchase activity of excess stock by the FHLB, and our 
intent and ability to hold this investment for a period of time sufficient to recover our recorded investment.  

NOTE 6—LOANS  

Non-Covered Loans  

        When we refer to non-covered loans we are referring to loans not covered by our FDIC loss sharing agreements.  

        The Company funds commercial, real estate and consumer loans to customers in the regions the Bank serves, which are mainly in Southern 
California. The non-covered foreign loans are primarily to individuals and entities located in Mexico. All of our non-covered foreign loans are 
denominated in U.S. dollars and the majority is collateralized by assets located in the United States or guaranteed or insured by businesses located 
in the United States.  

        The following table presents the composition of our non-covered loans by portfolio segment as of the dates indicated:

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

        At December 31, 2011 and 2010, the Company had no 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 when, in the opinion of 
management, there is a reasonable doubt as to collectibility in the normal course of business. At December 31, 2011, nonaccrual loans totaled 
$58.3 million. Nonaccrual loans included $2.5 million of loans 30 to 89 days past due and $37.4 million of current loans which were placed on 
nonaccrual status based on management's judgment regarding the collectibility of such loans.  

        During 2011, all past due categories were reduced due to charge-offs and foreclosure activity. Reduction in the residential real estate

NOTE 6—LOANS (Continued)  

PACWEST BANCORP AND SUBSIDIARIES  

Notes to Consolidated Financial Statements (Continued)  

        At December 31, 2011, we had commitments in the amount of $1,000 to lend on nonaccrual loans but are under no obligation to honor such 
commitment as long as the loan is on nonaccrual. We had commitments in the amount of $4.0 million to lend on performing restructured loans.  

        During 2011, non-covered nonaccrual loans declined by $35.9 million, to $58.3 million; this decrease in nonaccrual loans was attributable 
primarily to reductions, payoffs and returns to accrual status of $33.4 million, charge-offs of $24.5 million, and foreclosures of $34.9 million, offset 
partially by additions of $56.9 million.  

        During 2011, non-covered performing restructured loans increased by $27.5 million, to $116.8 million, at December 31, 2011. The growth in 
performing restructured loans was attributable to additions of $58.8 million, offset partially by the removal of $16.7 million in loans from 
restructured loan status due to the performance of the loans in accordance with their modified terms, and the transfers of performing restructured 
loans to nonaccrual status of $14.6 million. At December 31, 2011, we had $116.8 million in loans that were accruing interest under the terms of 
troubled debt restructurings. This amount consisted of $87.5 million in real estate mortgage loans, $24.5 million in real estate construction loans, 
$4.7 million in commercial loans and $144,000 in consumer loans.  

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

        The Company measures its impaired loans by using the estimated fair value of the collateral, less estimated costs to sell, including senior 
obligations such as delinquent property taxes, if the loan is collateral-dependent and the present value of the expected future cash flows 
discounted at the loan's effective interest rate if the loan is not collateral-dependent. The Company recognizes income from non-covered impaired 
loans on an accrual basis unless the loan is on nonaccrual status. Income from loans on nonaccrual status is recognized to the extent cash is 
received and the loan's principal balance is deemed collectible. For the years ended December 31, 2011, 2010, and 2009, no interest income was 
recorded on non-covered impaired loans during the time such loans were on nonaccrual status; any interest payments received were credited to 
principal.  

        The recorded investment in a loan reflects the contractual amount due from the borrower reduced by charge-offs and any participation amount 
sold to a third party. The Company's policy is to charge-off to the allowance the impairment amount on a collateral-dependent loan and to set up as 
a specific reserve within the allowance the impairment amount on a loan that is not collateral-dependent.

NOTE 6—LOANS (Continued)  

Covered Loans  

PACWEST BANCORP AND SUBSIDIARIES  

Notes to Consolidated Financial Statements (Continued)  

        We refer to the loans acquired in the Los Padres and Affinity acquisitions subject to loss sharing agreements with the FDIC as "covered 
loans" as we will be reimbursed for a substantial portion of any future losses on them under the terms of the agreements. At the respective 
acquisition dates, the estimated fair values of the Los Padres and Affinity covered loans were $436.3 million and $675.6 million. Fair value of 
acquired loans is determined using a discounted cash flow model using assumptions about the amount and timing of principal and interest 
payments, estimated prepayments, estimated default rates, estimated loss severity in the event of defaults, and current market rates. Estimated 
credit losses are included in the determination of fair value; therefore, an allowance for loan losses is not recorded on the acquisition date.  

        The following table reflects the carrying values of the covered loans as of the dates indicated:

        Federal Funds Arrangements with Commercial Banks.    As of December 31, 2011, 2010, and 2009, the Bank had unsecured lines of credit with 
correspondent banks, subject to availability, in the amount of $45.0 million, $52.0 million, and $117.0 million, respectively. These lines are renewable 
annually and have no unused commitment fees. As of December 31, 2011, 2010, and 2009, there were no balances outstanding.

        FRB Secured Line of Credit.    The Bank established a secured line of credit with the FRB during 2008. The secured borrowing capacity is 
collateralized by liens covering $439.1 million of our construction and commercial loans not already pledged to the FHLB as described below. As of 
December 31, 2011, our secured FRB borrowing capacity was $347.4 million. As of December 31, 2011, 2010 and 2009 and during such periods, there 
were no balances outstanding.  

        FHLB Secured Lines of Credit.    The borrowing arrangements with the FHLB are based on two separate FHLB programs and are collateralized 
by a portion of our securities available-for-sale and by a blanket lien covering the majority of our real estate secured loans. At December 31, 2011, 
approximately $2.7 billion of real estate and commercial loans and securities with a carrying value of $37.6 million are pledged to secure our FHLB

maturities for all advances. The callable advances have all passed their initial call dates and are currently callable on a quarterly basis by the FHLB. 
While the FHLB may call the advances to be repaid for any reason, they are likely to be called if market interest rates, for borrowings of similar 
remaining term, are higher than the advances' stated rates on the call dates. We may repay the advances at any time with a prepayment penalty.

NOTE 11—BORROWINGS AND SUBORDINATED DEBENTURES (Continued)  

Subordinated Debentures  

        The Company had an aggregate of $129.3 million and $129.6 million in subordinated debentures outstanding at December 31, 2011 and 2010, 
respectively. The subordinated debentures outstanding at December 31, 2011 were issued in seven separate series. Each issuance had a maturity 
of thirty years from its date of issue. Debt issuance costs are amortized on a straight-line basis over the period to the first call date. The 
subordinated debentures were issued to trusts established by us or entities we have acquired, which in turn issued trust preferred securities, 
which totaled $123.0 million at December 31, 2011. These trust preferred securities are presently considered Tier 1 capital for regulatory purposes.  

        The subordinated debentures are each callable at par with the exception of Trust I and Trust CI, which are callable at par with a prepayment 
penalty, and only by the issuer. The prepayment penalty for Trust I and Trust CI diminishes over time such that they may be called at par in the 
year 2020.  

        On March 7 and 8, 2012, the Company redeemed $18 million of the subordinated debentures of Trust 1 and Trust CI and recognized a pre-tax 
gain of approximately $1.6 million. We redeemed these subordinated debentures to reduce our cost of funds, as these two instruments carried fixed 
interest rates of 11.0% and 10.6%.  

        The proceeds of the subordinated debentures were used primarily to fund several of our acquisitions and to augment regulatory capital. 
Interest payments on subordinated debentures made by the Company are considered dividend payments by the Federal Reserve Bank. As such, 
notification to the Federal Reserve Bank is required prior to paying such interest during any period for which our quarterly net earnings are 
insufficient to fund the interest due. Should the FRB object to payment of interest on the subordinated debentures we would not be able to make 
the payments until approval is received or we no longer need to provide notice under applicable regulations.

This amount represents the fair value adjustment on the subordinated debentures issued to the trusts of acquired companies.  

NOTE 12—COMMITMENTS AND CONTINGENCIES  

Lending Commitments  

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

        The following presents a summary of the financial instruments described above as of the dates indicated:

        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. Of the $723.5 million of commitments to extend credit, $8.5 million is related to foreign loans.  

        Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. 
Those guarantees are primarily issued to support private borrowing arrangements. Most guarantees will expire within one year. The Company 
generally requires collateral or other security to support financial instruments with credit risk.  

        In addition, the Company has investments in low income housing project partnerships, which provide the Company income tax credits, and 
also in several small business investment companies. The investments call for capital contributions up to an amount specified in the partnership 
agreements. The Company had commitments to contribute capital to these entities totaling $7.1 million and $177,000 as of December 31, 2011 and 
2010, respectively.  

Legal Matters  

        In the ordinary course of our business, we are party to various legal actions, which we believe are incidental to the operation of our business.

ultimate resolution are inherently difficult to predict. In the opinion of management, based upon information currently available to us, any resulting 
liability, in addition to amounts already accrued, would not have a material adverse effect on the Company's financial statements or operations.  

NOTE 13—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 U.S. government and agency 
securities.  

Level 3: Inputs to a valuation methodology that are unobservable, supported by little or no market activity, and significant to the 
fair value measurement. These valuation methodologies generally include pricing models, discounted cash flow models, or a 
determination of fair value that requires significant management judgment or estimation. This category also includes observable 
inputs from a pricing service not corroborated by observable market data, such as pricing private label CMOs.  

        We use fair value to measure certain assets on a recurring basis, primarily securities available for sale; we have no liabilities being measured at 
fair value. For assets and liabilities 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 fair value of loans exceeded the carrying value at December 31, 2011, while the fair value of loans at December 31, 2010 was below the carrying value. When 
estimating the fair value, we apply a discount rate similar to the rate offered on loans at the time of the analysis. The reason for the change in the relationship of the 
fair value to the carrying value of loans at December 31, 2011 compared to December 31, 2010 is that the offered rate for certain of our commercial real estate loans 
was lower in December 2011 compared to December 2010 resulting in a lower discount rate and a relatively higher fair value.

NOTE 13—FAIR VALUE MEASUREMENTS (Continued)  

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

        Cash and Due from Banks and Federal Funds Sold.    The carrying amount is assumed to be the fair value because of the liquidity of these 
instruments.  

        Interest-Earning Deposits in Financial Institutions.    The carrying amount is assumed to be the fair value given the short-term nature of 
these deposits.  

        FHLB stock.    The fair value of FHLB stock is based on our recorded investment. In January 2009, the FHLB announced that it suspended 
excess FHLB stock redemptions and dividend payments. Since this announcement, the FHLB has declared and paid cash dividends in 2010 and 
2011, though at rates less than those paid in the past, and repurchased certain amounts of our excess stock at the carrying value. We evaluated the 
carrying value of our FHLB stock investment at December 31, 2011 and 2010, and determined that it was not impaired. Our evaluation considered 
the long-term nature of the investment, the current financial and liquidity position of the FHLB, the actions being taken by the FHLB to address its 
regulatory situation, repurchase activity of excess stock by the FHLB, and our intent and ability to hold this investment for a period of time 
sufficient to recover our recorded investment.  

        Securities available-for-sale.    Securities available-for-sale are measured and carried at fair value on a recurring basis. Unrealized gains and 
losses on available-for-sale securities are reported as a component of accumulated other comprehensive income in the consolidated balance 
sheets. Also see Note 5, Investment Securities, for further information on unrealized gains and losses on securities available-for-sale.  

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

        Our covered private label collateralized mortgage obligation securities, which we refer to as private label CMOs, are categorized as Level 3 due 
in part to the inactive market for such securities. There is a wide range of prices quoted for private label CMOs among independent third party 
pricing services and this range reflects the significant judgment being exercised over the assumptions and variables that determine the pricing of 
such securities. We consider this subjectivity to be a significant unobservable input and have concluded that the private label CMOs should be 
categorized as a Level 3 measured asset. Our fair value estimate was based on prices provided to us by a nationally recognized pricing service 
which we also use to determine the fair value of the majority of our securities portfolio. We determined the reasonableness of the fair values by 
reviewing assumptions at the individual security level about prepayment, default expectations, estimated severity loss factors, projected cash 
flows and

estimated collateral performance, all of which are not directly observable in the market. During 2010, we recorded $874,000 in losses on one covered 
impaired security with a resulting fair value of zero.  

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

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

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

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

        The non-covered impaired loan balances shown above represent those nonaccrual and restructured loans for which impairment was 
recognized during 2011 and 2010. The amounts shown as losses represent, for the loan balances shown, the impairment recognized during the 
years ended December 31, 2011, 2010, and 2009. Of the $58.3 million of nonaccrual loans at December 31, 2011, $18.2 million were written down to 
their fair values through charge-offs during 2011.  

        Other real estate owned.    The fair value of foreclosed real estate, both non-covered and covered, is generally based on estimated market 
prices from independently prepared current appraisals or negotiated sales prices with potential buyers, less estimated costs to sell; such valuation 
inputs result in a fair value measurement that is categorized as a Level 2 measurement on a nonrecurring basis. As a matter of policy, appraisals are 
required annually and may be updated more frequently as  

153

PACWEST BANCORP AND SUBSIDIARIES  

Notes to Consolidated Financial Statements (Continued)  

NOTE 13—FAIR VALUE MEASUREMENTS (Continued)  

circumstances require in the opinion of management. The Level 2 measurement for OREO is based on appraisals obtained within the last 12 months 
and for which a write-down was recognized in 2011 and 2010.  

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

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

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

        Borrowings.    Borrowings are carried at amortized cost. The fair value of fixed rate borrowings is calculated by discounting scheduled cash 
flows through the estimated maturity or call dates using estimated market discount rates that reflect current rates offered for borrowings with 
similar remaining maturities and characteristics.  

        Subordinated debentures.    Subordinated debentures are carried at amortized cost. In accordance with ASC Topic 825, the fair value of the 
subordinated debentures is based on the discounted value of contractual cash flows for fixed rate securities. The discount rate is estimated using 
the rates currently offered for similar securities of similar maturity. The fair value of subordinated debentures with variable rates is deemed to be the 
carrying value.  

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

NOTE 13—FAIR VALUE MEASUREMENTS (Continued)  

Limitations  

        Fair value estimates are made at a specific point in time and are based on relevant market information and information about the financial 
instrument. These estimates do not reflect income taxes or any premium or discount that could result from offering for sale at one time the 
Company's entire holdings of a particular financial instrument. Because no market exists for a portion of the Company's financial instruments, fair 
value estimates are based on what management believes to be conservative judgments regarding expected future cash flows, current economic 
conditions, risk characteristics of various financial instruments, and other factors. These estimated fair values are subjective in nature and involve 
uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly 
affect the estimates. Since the fair values have been estimated as of December 31, 2011 and 2010, the amounts that will actually be realized or paid 
at settlement or maturity of the instruments could be significantly different.

        Based upon our taxpaying history and estimates of taxable income over the years in which the items giving rise to the deferred tax assets are 
deductible, management believes it is more likely than not the Company will realize the benefits of these deductible differences.  

        We adopted the provisions of ASC Topic 740, "Income Taxes," which relate to the accounting for uncertainty in income taxes recognized in an 
enterprise's financial statements on January 1, 2007. ASC Topic 740 prescribes a threshold and a measurement process for recognizing in the 
financial statements a tax position taken or expected to be taken in a tax return. ASC Topic 740 also provides guidance on derecognition, 
classification, interest and penalties, accounting in interim periods, disclosure and transition.  

        Our evaluation of tax positions was performed for those tax years which remain open to audit. As of December 31, 2011, all the federal returns 
filed since 2008 and state returns filed since 2007 are subject to adjustment upon audit.

        While it is expected that the amount of unrecognized tax benefits may change in the next twelve months, the Company does not expect this 
change to have a material impact on the results of operations or the financial position of the Company. We may from time to time be assessed 
interest or penalties by taxing authorities, although any such assessments historically have been minimal and immaterial to our financial results. In 
the event we are assessed for interest and/or penalties, such amounts will be classified in the financial statements as income tax expense.

NOTE 16—STOCK COMPENSATION PLANS  

        The Company's 2003 Stock Incentive Plan, or the 2003 Plan, permits stock-based compensation awards to officers, directors, key employees 
and consultants. The 2003 Plan authorizes grants of stock-based compensation instruments to purchase or issue up to 5,000,000 shares of 
authorized but unissued Company common stock, subject to adjustments provided by the 2003 Plan. In May 2011, the Board of Directors approved 
the equity award of 13,740 common shares to non-employee directors of the Company. Such shares were granted outright and vested immediately 
with a charge to other noninterest expense of $300,000 at that time. As of December 31, 2011, there were 514,365 shares available for grant under the 
2003 Plan.

        At December 31, 2011, there were outstanding 825,730 shares of unvested time-based restricted common stock and 850,000 shares of unvested 
performance-based restricted common stock. The awarded shares of time-based restricted common stock vest over a service period of three to five 
years from the date of the grant. The awarded shares of performance-based restricted common stock vest in full on the date the Compensation, 
Nominating and Governance, or CNG, Committee of the Board of Directors, as Administrator of the 2003 Plan, determines that the Company 
achieved certain financial goals established by the CNG Committee as set forth in the award documents. Both time-based and performance-based 
restricted common stock vest immediately upon a change in control of the Company as defined in the 2003 Plan and upon death of the employee.  

        In March 2011, the CNG awarded 350,000 shares of performance-based restricted common stock, which will expire on March 31, 2016 if the net 
earnings performance target established for such awards is not met. Such restricted stock will vest upon a change in control, however, as defined 
in the 2003 Plan. We have determined that it is not probable at the present time that the net earnings performance target will be achieved. 
Accordingly, no expense is being recognized for these shares.  

        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 $7.6 million, $8.5 million, and $8.2 million 
for the years

ended December 31, 2011, 2010, and 2009, respectively. Such amounts are included in compensation expense on the accompanying consolidated 
statements of earnings (loss). As of December 31, 2011, total unrecognized compensation cost related to unvested time-based restricted stock was 
$11.4 million. This cost is expected to be recognized over a weighted average period of 1.6 years.  

        Currently no compensation expense is being recognized for any performance-based restricted stock awards as management has concluded 
that it is improbable that the respective financial targets for any outstanding performance-based restricted stock awards will be met. If and when 
the attainment of such financial targets is deemed probable in future periods, a catch-up adjustment will be recorded and amortization of such 
performance-based restricted stock will begin again. The total amount of unrecognized compensation expense related to all performance-based 
restricted stock for which amortization was suspended or has not commenced totaled $33.8 million at December 31, 2011 as presented in the

NOTE 17—BENEFIT PLANS  

401(K) Plans  

        The Company sponsors a defined contribution plan for the benefit of its employees. Participants are eligible to participate immediately as long 
as they work a minimum of 1,000 hours and are at least 21 years of age. Eligible participants may contribute up to 60% of their annual 
compensation, not to exceed the dollar limit imposed by the Internal Revenue Code. Employer contributions are determined annually by the Board 
of Directors in accordance with plan requirements and applicable tax code.  

        Expense related to 401(k) contributions was $433,000, $498,000, and $430,000 for the years ended December 31, 2011, 2010, and 2009, 
respectively.  

NOTE 18—STOCKHOLDERS' EQUITY

initial offering price of up to $350 million. This registration statement was declared effective on January 8, 2010. Proceeds from any offering under 
this registration statement are anticipated to be used to fund future acquisitions of banks and other financial services companies and for general 
corporate purposes.  

        On August 25, 2009, PacWest Bancorp sold in a direct placement to institutional investors 2.7 million shares of common stock for $50 million, 
or a per share price of $18.36, which was the closing price of PacWest's common stock on Monday, August 24, 2009. In addition to the issuance of 
the common shares, PacWest issued to each investor two warrants exercisable for common shares worth up to an additional $50 million in the 
aggregate with an exercise price of $20.20 per share, or 110% of the price per share at which the initial $50 million was sold. The Series A warrants 
had a six month term and originally expired on March 1, 2010; such warrants were exercised on March 1, 2010 for a total of $27.2 million in cash and 
we issued 1,348,040 shares of common stock. The net proceeds from the warrant exercises totaled $26.6 million after expenses. The 1,361,657 
Series B warrants issued in August 2009 with a strike price of $20.20 expired in August 2010 without being exercised. The common shares were sold 
and the warrants were issued under our $150 million shelf registration statement, which became effective in June 2009, but was subsequently 
terminated upon the effectiveness declaration of our $350 million shelf registration statement on January 8, 2010.  

        On January 14, 2009, we issued in a private placement to CapGen Capital Group II LP 3,846,153 PacWest common shares at $26 per share for 
total cash consideration of approximately $100 million. CapGen Capital Group II LP has registered as a bank holding company and as a result of the 
investment it owned approximately 11% of PacWest outstanding common stock, excluding unvested restricted stock, as of December 31, 2011.  

        As a Delaware corporation, the Company records treasury shares for shares surrendered to the Company resulting from statutory payroll tax 
obligations arising from the vesting of restricted stock. During 2011, the Company purchased 80,173 treasury shares at a weighted average price of 
$18.27 per share. During 2010, the Company purchased 94,666 treasury shares at a weighted average price of $19.34 per share. During 2009, the 
Company purchased 100,770 treasury shares at a weighted average price of $17.62 per share.  

NOTE 19—DIVIDEND AVAILABILITY AND REGULATORY MATTERS  

        Holders of Company common stock are entitled to receive dividends declared by the Board of Directors out of funds legally available under 
state law governing the Company and certain federal laws and regulations governing the banking and financial services business. Our ability to 
pay dividends to our stockholders is subject to the restrictions set forth in Delaware General Corporation Law and certain covenants contained in 
the indentures governing trust preferred securities issued by us or entities that we have acquired. Notification to the Federal Reserve Bank 
("FRB") is also required prior to our declaring and paying dividends on common stock during any period in which our quarterly net earnings is 
insufficient to fund the dividend amount. Should the FRB object to payment of dividends on common stock, we would not be able to make the 
payment until approval is received or we no longer need to provide notice under applicable regulations.  

        It is possible, depending upon the financial condition of the Bank, and other factors, that the FRB, the FDIC or the California Department of 
Financial Institutions ("DFI"), could assert that payment of dividends or other payments is an unsafe or unsound practice. Pacific Western is 
subject to restrictions  

162

PACWEST BANCORP AND SUBSIDIARIES  

Notes to Consolidated Financial Statements (Continued)  

NOTE 19—DIVIDEND AVAILABILITY AND REGULATORY MATTERS (Continued)  

under certain federal and state laws and regulations governing banks which limit its ability to transfer funds to the holding company through 
intercompany loans, advances or cash dividends. Dividends paid by state banks such as Pacific Western are regulated by the DFI under its 
general supervisory authority as it relates to a bank's capital requirements. A state bank may declare a dividend without the approval of the DFI as 
long as the total dividends declared in a calendar year do not exceed either the retained earnings or the total of net earnings for three previous 
fiscal years less any dividend paid during such period. During 2011, PacWest received $25.5 million in dividends from the Bank. For the foreseeable 
future, further dividends from the Bank to the Company will require DFI approval.  

        PacWest, as a bank holding company, is subject to regulation by the Board of Governors of the Federal Reserve System under the Bank 
Holding Company Act of 1956, as amended. The Federal Deposit Insurance Corporation Improvement Act of 1991 required that the federal 
regulatory agencies adopt regulations defining capital tiers for banks: well capitalized, adequately capitalized, undercapitalized, significantly 
undercapitalized and critically undercapitalized. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional 
discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company's consolidated financial statements. 
Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific 
capital guidelines that involve quantitative measures of the Company's and the Bank's assets, liabilities and certain off-balance sheet items as 
calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the 
regulators about components, risk weightings and other factors.  

        Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts 
and ratios of total and Tier I capital to risk-weighted assets, and of Tier I capital to average assets ("leverage ratio"). Tier 1 Capital includes 
common stockholders' equity, trust preferred securities, less goodwill and certain other deductions (including a portion of servicing assets and the 
unrealized net gains and losses, after taxes on securities available for sale). Total risk-based capital includes Tier 1 capital and other items such as 
subordinated debt and the allowance for credit losses. Both measures are stated as a percentage of risk-weighted assets, which are measured 
based on their perceived credit risk and include certain off-balance sheet exposures, such as unfunded loan commitments and letters of credit. The 
Company is also subject to a leverage ratio requirement, a non risk-based asset ratio, which is defined as Tier 1 Capital as a percentage of average 
assets, adjusted for goodwill and other non-qualifying intangibles and other assets.  

        Bank holding companies considered to be "adequately capitalized" are required to maintain a minimum total risk-based capital ratio of 8% of 
which at least 4.0% must be Tier 1 capital and a minimum leverage ratio of 4.0%. Bank holding companies considered to be "well capitalized" must 
maintain a minimum risk-based capital ratio of 10.0% of which at least 6.0% must be Tier 1 capital and a minimum leverage ratio of 5%. As of 
December 31, 2011, the most recent notification date to the regulatory agencies, the Company and the Bank are each "well capitalized" under the 
regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have 
changed the Company's or any of the Bank's categories.  

        Management believes, as of December 31, 2011, that we have met all capital adequacy requirements to which we are subject.

NOTE 19—DIVIDEND AVAILABILITY AND REGULATORY MATTERS (Continued)  

        Regulatory capital requirements limit the amount of deferred tax assets that may be included when determining the amount of regulatory 
capital. Deferred tax asset amounts in excess of the calculated limit are deducted from regulatory capital. At December 31, 2011, such amount was 
$27.4 million for the Company and $21.9 million for the Bank. No assurance can be given that the regulatory capital deferred tax asset limitation will 
not increase in the future. The following table presents actual capital amounts and ratios for the Company and the Bank as of the dates indicated:

PACWEST BANCORP AND SUBSIDIARIES  

Notes to Consolidated Financial Statements (Continued)  

NOTE 19—DIVIDEND AVAILABILITY AND REGULATORY MATTERS (Continued)  

        The Company issued subordinated debentures to trusts that were established by us or entities we have acquired, which, in turn, issued trust 
preferred securities, which totaled $123.0 million at December 31, 2011. The Company includes in Tier 1 capital an amount of trust preferred 
securities equal to no more than 25% of the sum of all core capital elements, which is generally defined as shareholders' equity less goodwill, net of 
any related deferred income tax liability. At December 31, 2011, the amount of trust preferred securities included in Tier I capital was $123.0 million. 
While our existing trust preferred securities are grandfathered under the Dodd-Frank Wall Street Reform and Consumer Protection Act that was 
enacted in July 2010, new issuances will not qualify as Tier 1 capital. See Note 11, Borrowings and Subordinated Debentures, and Note 23, 
Subsequent Events, for information regarding the redemption on March 7 and 8, 2012 of certain of our subordinated debentures.  

        Interest payments made by the Company to subordinated debentures are considered dividend payments by the Federal Reserve Bank. As 
such, notification to the Federal Reserve Bank is required prior to our intent to pay such interest during any period in which our quarterly net 
earnings are not sufficient to fund the interest due. Should the FRB object to payment of interest on the subordinated debentures we would not be 
able to make the payments until approval is received or we no longer need to provide notice under applicable regulations.  

NOTE 20—CONDENSED FINANCIAL INFORMATION OF PARENT COMPANY  

        The parent company only condensed balance sheets as of December 31, 2011 and 2010 and the related condensed statements of net earnings

        The following table sets forth our unaudited, quarterly results for the periods indicated. For all such periods, we reclassified recoveries on 
covered loans such that recoveries now reduce the credit loss provision for covered loans rather than increase FDIC loss sharing income. Such 
reclassifications had no effect on reported net earnings or losses.

which is controlled by the Company's chairman. During 2011, 2010, and 2009, there were no amounts paid by the Company to Castle Creek 
Financial.  

        As of December 31, 2011 and 2010, there were no loans outstanding to any members of our board of directors or executive management. Such 
parties' deposits as of those dates totaled $4.6 million and $6.1 million, respectively, and bear market rates and terms.  

NOTE 23—SUBSEQUENT EVENTS (Unaudited)  

        On January 3, 2012, Pacific Western Bank completed the acquisition of Marquette Equipment Finance, or MEF, an equipment leasing company 
located in Midvale, Utah. Pacific Western Bank acquired all of the capital stock of MEF from Meridian Bank, N.A. for $35 million in cash.  

        At January 3, 2012, MEF had $162.2 million in gross leases and leases in process outstanding, with no leases on nonaccrual status. In 
addition, Pacific Western Bank assumed $154.8 million in outstanding debt and other liabilities, which included $129 million payable to MEF's 
former parent.

        All of the MEF goodwill is expected to be deductible for tax purposes.  

        On March 7 and 8, 2012, the Company redeemed $18 million of the subordinated debentures of Trust I and Trust CI and recognized a pre-tax 
gain of approximately $1.6 million. We redeemed these subordinated debentures to reduce our cost of funds, as these two instruments carried fixed 
interest rates of 11.0% and 10.6%.  

        We have evaluated events that have occurred subsequent to December 31, 2011 and have concluded there are no subsequent events that 
would require recognition in the accompanying consolidated financial statements.
