8APR201410324547 March 31, 2017 To Our Stockholders: PacWest Bancorp (‘‘PacWest’’) delivered another year of superior operating and financial results in 2016 despite challenging macroeconomic conditions, the headwind of a continued low interest rate environment, increasing market competition, and heightened regulatory demands. PacWest’s consistently strong financial performance is attributable to our commitment to creating long-term value for our stockholders through our continued focus on profitability, controlling operating expenses, optimizing margins, building a stable and low cost core deposit base, generating prudent and profitable loan and lease growth, and proactively managing credit and other risks. Key operating metrics and highlights for 2016 include: (cid:129) Net earnings of $352.2 million, or $2.90 per diluted share; (cid:129) Industry-leading return on assets of 1.66%, return on tangible equity of 15.52%, and tax equivalent net interest margin of 5.40%; (cid:129) Net loan and lease growth of $977.7 million, or 7%; (cid:129) Core deposit growth of $2.0 billion, or 18.5%, with the core deposit ratio increasing to 79% of total deposits; (cid:129) Net charge-offs of 15 basis points; (cid:129) A solid tangible common equity-to-assets ratio of 11.5%; and (cid:129) Closely controlled operating expenses during the year, with an efficiency ratio of 39.8%. Our strong operating and financial performance, initial Dodd-Frank Act stress test submission and robust capital levels for 2016 allowed us to continue distributing an annual $2.00 per share cash dividend, providing a yield among the highest in the banking industry. On October 17, 2016, the PacWest Board of Directors (the ‘‘Board’’) also authorized a $400 million stock repurchase program in order to actively manage capital levels and return value to our stockholders. While we have only repurchased $27.9 million of stock to date due to current market conditions, this authorization reflects our confidence and underscores our continued commitment to enhancing long-term stockholder value. We remain in a favorable position of tremendous capital flexibility and will continue to invest in financially accretive and strategically compelling acquisitions. Our financial and competitive strength have not gone unnoticed. Forbes magazine recently ranked PacWest the best of the 100 largest publicly-traded U.S. banks on its 2017 List of America’s Best Banks. As a company built through organic growth and disciplined acquisitions, this honor would not be possible without the professionalism, dedication and commitment of our employees. Their tireless efforts during our recent acquisition and integration of Square 1 serve as a reminder of how PacWest is always looking to the future. Thanks to our employees, we have made excellent progress with a phase completed on our conversion to a new core processing system in January 2017 and we look forward to the final phases of the conversion later this year. On behalf of our Board and the entire executive management team, I would like to thank our employees, customers and stockholders for their continued support. As the owners of PacWest, you can trust that the Board and executive management will always work to sustain PacWest’s performance in areas where our results are already strong and that we will diligently address the areas of our performance in which we see the greatest opportunities for improvement. We have excellent internal momentum combined with a more favorable economic and interest rate outlook as we enter 2017 and I am confident in our ability to continue delivering long-term value for our stockholders.

Our CapitalSource Division provides cash flow, asset-based, equipment, and real estate loans and treasury management services to established middle market businesses on a national basis. Our Square 1 Bank Division offers a comprehensive suite of financial services focused on entrepreneurial businesses and their venture capital and private equity investors, with offices located in key innovation hubs across the United States. In addition, we provide investment advisory and asset management services to select clients through Square 1 Asset Management, Inc., a wholly-owned subsidiary of the Bank and a SEC-registered investment adviser. PacWest Bancorp was established in October 1999 and has achieved strong market positions by developing and maintaining extensive local relationships in the communities we serve. By leveraging our business model, service-driven focus, and presence in attractive markets, as well as maintaining a highly efficient operating model and robust approach to risk management, we have achieved significant and profitable growth, both organically and through disciplined acquisitions. We have successfully completed 28 acquisitions since 2000 which have contributed to our growth and expanded our market presence throughout the United States. As of December 31, 2016, we had total assets of $21.9 billion, loans and leases, net of deferred fees, of $15.5 billion, total deposits of $15.9 billion, and stockholders’ equity of $4.5 billion. Our Business Strategy General Overview We believe that stable, long-term growth and profitability are the result of building strong customer relationships while maintaining disciplined credit underwriting standards. We continue to focus on originating high-quality loans and leases and growing our low-cost deposit base through our relationship-based business lending. These core strengths enable us to maintain our operational efficiency, increase profitability, increase our core deposits, and grow loans and leases in a sound manner. Our loan and lease portfolio consists primarily of real estate mortgage loans, real estate construction and land loans, and C&I loans and leases. We pursue attractive growth opportunities to expand and enter new markets aligned with our business model and strategic plans. Additionally, we focus on cultivating strong relationships with private equity and venture capital firms nationwide, many of which are also our clients and/or may invest in our clients. 7 Our reputation, expertise and relationship-based business banking model enable us to deepen our relationships with our customers. We leverage our relationships with existing customers by cross-selling our products and services, including attracting deposits from and offering cash management solutions to our loan and lease customers. We price our deposit products with a view to maximizing our share of each customer’s financial services business and prudently managing our cost of funds. Focusing on operational efficiency is critical to our profitability and future growth. We carefully manage our cost structure and continuously refine and implement internal processes and systems to create further efficiencies and enhance our earnings. We have substantially completed our efforts to adjust the mix of our deposit base by reducing the proportion of certificates of deposit, a strategic initiative that was undertaken following the CapitalSource Inc. merger. The acquisition of Square 1 accelerated this process as substantially all of the $3.8 billion of acquired deposits were core deposits. The Square 1 Bank Division’s core deposits have increased to over $5.3 billion at December 31, 2016. Our management team has extensive expertise and a successful track record in evaluating, executing and integrating attractive, franchise-enhancing acquisitions. We have successfully completed 28 acquisitions since 2000, including the Square 1 acquisition in 2015 and the CapitalSource Inc. merger in 2014. We will continue to consider acquisitions that are consistent with our business strategy and financial model as opportunities arise. Depository Products and Services Deposits are our primary source of funds to support our interest-earning assets and provide a source of stable low-cost funds and deposit-related fee income. We offer traditional deposit products to businesses and other customers with a variety of rates and terms, including demand, money market, and time deposits. We also provide international banking services, multi-state deposit services, and asset management services. The Bank’s deposits are insured by the FDIC up to statutory limits. Our branch network allows us to gather deposits, expand our brand presence and service our customers’ banking and cash management needs. In addition, as the banking industry continues to experience broader customer acceptance of on-line and mobile banking tools for conducting basic banking functions we are able to serve our customers through a wide range of non-branch channels, including on-line, remote deposit, and telephone banking platforms, which allows us to expand our service area to attract new depositors without a commensurate increase in branch locations or branch traffic. At December 31, 2016, we had ATMs at 60 of our branches and two at off-site locations located in California. We are part of the MoneyPass network that enables our customers to withdraw cash surcharge-free and service charge-free at over 25,000 ATM locations across the country. We provide access to customer accounts via a 24 hour seven-day-a-week, toll-free, automated telephone customer service and secure on-line banking services. The composition of our deposit mix changed as a result of the CapitalSource Inc. merger, which lowered the proportion of core deposits and increased the proportion of more expensive time deposits. Since the CapitalSource Inc. merger, we have focused on shifting the mix of deposits to include a higher proportion of core deposits. Our dedicated team of professionals has been successful in growing our low-cost, core deposit base by attracting deposits from our business customers and offering alternative cash management solutions intended to help retain business customers. The Square 1 acquisition completed in October 2015 accelerated this shift in deposit mix as the percentage of core deposits increased to 79% at the end of 2016. At December 31, 2016, our total deposits consisted of $12.5 billion in core deposits, $2.2 billion in time deposits and $1.2 billion in brokered non-maturity deposits. Core deposits represented 79% of total deposits at December 31, 2016, and were comprised of $6.7 billion in noninterest-bearing deposits, 8 $1.4 billion in interest-bearing checking accounts, $3.7 billion in money market accounts and $0.7 billion in savings accounts. Our deposit base is also diversified by client type. As of December 31, 2016, no individual depositor represented more than 1.4% of our total deposits, and our top ten depositors represented 8.0% of our total deposits. We face strong competition in gathering deposits. Our most direct competition for deposits comes from nationwide, regional, and community banks, savings banks and associations, credit unions, insurance companies, money market funds, brokerage firms and other non-bank financial services companies that target the same customers as we do. We compete actively for deposits and emphasize solicitation of noninterest-bearing deposits. We seek to provide a higher level of personal service than our larger competitors, many of whom have more assets, capital and resources than we do and who may be able to conduct more intensive and broader based promotional efforts to reach potential customers. Our cost of funds fluctuates with market interest rates and may be affected by higher rates being offered by other financial institutions. In certain interest rate environments, additional significant competition for deposits may be expected to arise from corporate and government debt securities and money market mutual funds. Competition for deposits is also affected by the ease with which customers can transfer deposits from one institution to another. Client Investment Funds In addition to deposit products, we also offer select clients non-depository cash investment options through S1AM, our registered investment adviser subsidiary, and third-party money market sweep products. S1AM provides customized investment advisory and asset management solutions. At December 31, 2016, total off-balance sheet client investment funds were $1.3 billion, of which $1.1 billion was managed by S1AM. Lending Activities We conduct commercial lending activities that include real estate mortgage loans, real estate construction and land loans, and C&I loans and leases. Our commercial real estate loans are secured by a range of property types. Our C&I loan offerings are diverse and generally include various asset- secured loans, equipment-secured loans and leases, cash flow loans (leveraged loans) to finance business acquisitions and recapitalizations, and venture loans to support the operations of entrepreneurial companies during the various phases of their life cycle. We price loans to preserve our interest spread and maintain our net interest margin. Loan interest rates may be floating, fixed, or a combination thereof (‘‘hybrid’’) throughout the loan term. The rates on hybrid loans typically are fixed until a ‘‘reset’’ date when the rates then become floating. While we do not actively solicit direct consumer loans, we hold consumer loans, consisting primarily of purchased private student loans originated and serviced by a third-party lender. Some of our loans are participations in larger loans, and these participations may be deemed a shared national credit, or SNC. A SNC is any loan or formal loan commitment extended to borrowers by a federally supervised institution that aggregates to $20 million or more and is shared by three or more unaffiliated federally supervised institutions, or a portion of which is sold to two or more unaffiliated federally supervised institutions. At December 31, 2016 and 2015, we had SNC loans to 116 borrowers that totaled $2.3 billion and to 103 borrowers that totaled $2.1 billion. The SNC program is governed by an inter-agency agreement among the FRB, the FDIC, and the Office of the Comptroller of the Currency. These agencies review a selection of SNCs periodically, with such review conducted at the lead or agent bank, and deliver a credit risk rating to the participants holding the loans. 9 Real Estate Loans Our real estate lending activities focus primarily on loans to professional developers and real estate investors for the acquisition, refinancing, renovation, and construction of commercial real estate. We also provide commercial real estate loans to borrowers operating businesses at these sites (owner- occupied commercial real estate loans). Our real estate loans generally are collateralized by first deeds of trust on specific commercial properties. The most prevalent types of properties securing our real estate loans are multi-family properties, various healthcare properties such as skilled nursing facilities and assisted living facilities, office properties, hotels, industrial properties, and retail properties. The properties are located across the United States, primarily in central business districts, but a substantial percentage of our real estate collateral is in California. Our real estate loans generally have an initial interest-only period followed by an amortization schedule with a lump sum balloon payment due in one to ten years or may, more immediately, have interest and principal payments due on an amortization schedule ranging from 25 to 30 years with a lump sum balloon payment due in one to ten years. Construction loans typically finance from 50% to 70% of the costs to construct commercial or multi- family residential properties. The terms are generally one to three years with short-term, performance- based extension options. We also provide real estate secured loans under the SBA’s 7(a) Program and 504 Program. Compliant SBA 7(a) loans have an SBA guaranty for 75% of the principal balance. SBA 504 loans are 50% loan-to-value first deed of trust mortgage loans on owner-occupied commercial real estate where a second deed of trust is also provided by a nonprofit certified development company. The SBA 7(a) and SBA 504 mortgage loans repay on a twenty-five year amortization schedule. We specialize in real estate loans secured by healthcare properties, primarily skilled nursing facilities. In addition to the points below, for a healthcare real estate loan, we evaluate facility clinical compliance and quality of care, assess the loan-to- value using per bed limitations based on market information, and analyze the payor mix and state and federal revenue sources. Our real estate portfolio is subject to certain risks including, but not limited to, the following: (cid:129) increased competition in pricing and loan structure; (cid:129) the economic conditions of the United States; (cid:129) interest rate increases; (cid:129) decreased real estate values in the markets where we lend; (cid:129) the borrower’s inability to repay our loan due to decreased cash flow or operating losses; (cid:129) the borrower’s inability to refinance or payoff our loan upon maturity; (cid:129) loss of our loan principal stemming from a collateral foreclosure; and (cid:129) various environmental risks, including natural disasters. In addition to the foregoing, construction loans are also subject to project-specific risks including, but not limited to, the following: (cid:129) construction costs being more than anticipated; (cid:129) construction taking longer than anticipated; (cid:129) failure by developers and contractors to meet project specifications; (cid:129) disagreement between contractors, subcontractors and developers; (cid:129) demand for completed projects being less than anticipated; and 10 (cid:129) buyers of the completed projects not being able to secure permanent financing. Many of the risks outlined above result from market conditions and are not controllable by us. When considering the markets in which to pursue real estate loans, we consider the market conditions, our current loan portfolio concentrations by property type and by market, and our past experiences with the borrower, within the specific market, and with the property type. When underwriting real estate loans, we seek to mitigate risk by using the following framework: (cid:129) reviewing each loan request and renewal individually; (cid:129) using a credit committee approval process for the approval of each loan request (or aggregated credit exposures) over a certain dollar amount; (cid:129) adhering to written loan policies including, among other factors, minimum collateral requirements, maximum loan-to-value/cost ratio requirements, and cash flow requirements; (cid:129) considering market rental rates relative to our underwritten rental rates: (cid:129) evaluating the supply of comparable real estate and new supply under construction in the collateral’s market area; (cid:129) obtaining independent third-party appraisals that are reviewed by our appraisal department; (cid:129) obtaining environmental risk assessments; and (cid:129) obtaining seismic studies where appropriate. With respect to construction loans, in addition to the foregoing, we attempt to mitigate project- specific risks by: (cid:129) implementing a controlled disbursement process for loan proceeds in accordance with an agreed upon schedule; (cid:129) conducting project site visits and using construction consultants who review the progress of the project; and (cid:129) monitoring the construction costs compared to the budgeted costs and the remaining costs to complete. SBA 7(a) and 504 program loans are subject to the risks outlined above and the risk that an SBA 7(a) guaranty may be invalid if SBA specific procedures are not followed. We seek to mitigate this risk by maintaining and adhering to additional policies specific to SBA loans which align with SBA requirements. C&I Loans and Leases Our C&I loan and lease offerings are diverse and generally include various cash flow loans (leveraged loans) to finance business acquisitions and recapitalizations, asset-based loans, equipment- secured loans and leases, and venture-backed loans to support the operations of entrepreneurial companies during the various phases of their life cycle. Our C&I loans include the following specific lending products: (cid:129) Cash flow loans. These loans include senior secured loans (leveraged loans) provided to entities in conjunction with equity contributions from private equity groups to finance the acquisition or recapitalization of a business, SBA 7(a) loans for small business expansion, loans to professionals and other business loans. The majority of our cash flow loans are made to borrowers with a high degree of recurring contractual revenues operating primarily in the technology, healthcare and security monitoring sectors. We also, on a more select basis, make cash flow loans to businesses 11 operating in a broader array of industries, targeting borrowers that are mature businesses with leading market shares. For cash flow loans, the primary sources of repayment are cash flow from operations, the refinancing of the loan, and/or the proceeds from the sale of the company. The loan terms are three to six years with some amortization during the term. Most of our cash flow loans are participations in larger loans, and most of these participations are SNCs. According to regulatory guidance, the majority of cash flow loans are considered leveraged loans. Leveraged loans are typically loans where the proceeds are used for buyouts or acquisitions and where the resulting total debt levels are four or more times the in-place historical adjusted earnings of the borrower. Leveraged loans are supported by underwriting that indicates the debt levels relative to earnings will decline meaningfully over the terms of the loans and for which the enterprise value provides sufficient coverage for our debt. The SBA 7(a) loans are secured by the value of a business and its equipment and are fully-amortizing term loans generally over a 10-year period. (cid:129) Asset-based loans. These loans are used for working capital and are secured by finance receivables, trade accounts receivable, and/or inventory. In conjunction with our healthcare real estate loans, we may provide healthcare operators with asset-based loans secured by healthcare accounts receivable to support working capital needs. This loan segment includes lender finance loans or loans to finance companies and timeshare operators. These loans are used to purchase finance receivables or extend finance receivables to the underlying obligors and are secured primarily by the finance receivables owed to our borrowers. The primary sources of repayment are the operating income of the borrower, the collection of the receivables securing the loan, and/or the sale of the inventory securing the loan. The loans are typically revolving lines of credit with terms of one to three years. Also included in this segment are loans used to finance annual life insurance premiums and are fully secured by the corresponding cash surrender value of life insurance contracts and other liquid collateral with one year terms that generally renew annually. (cid:129) Venture capital loans. These loans are to venture-backed companies to support their operations, including operating losses, working capital requirements and fixed asset acquisitions. Our borrowers are at various stages in their development and are generally reporting operating losses. The primary sources of repayment are future additional venture capital equity investments, or the sale of the company or its assets. This loan segment also includes loans directly to venture capital firms, venture capital funds, and venture capital management companies to provide a bridge to the receipt of capital calls and to support the borrowers’ working capital needs, such as the cost of raising a new venture fund or leasehold improvements for new office space. The primary sources of repayment are receipt of capital calls, exits from portfolio company investments, or management fees. The loan terms for venture loans are generally one to four years. (cid:129) Equipment-secured loans and leases. These loans and leases are used to purchase equipment essential to the operations of our borrower or lessee and are secured by the specific equipment financed. The primary source of repayment is the operating income of the borrower or lessee. The loan and lease terms are two to ten years and generally amortize to either a full repayment or residual balance or investment that is expected to be collected through a sale of the equipment to the lessee or a third party. Our portfolio of C&I loans and leases is subject to certain risks including, but not limited to, the following: (cid:129) the economic conditions of the United States; (cid:129) interest rate increases; (cid:129) deterioration of the value of the underlying collateral; 12 (cid:129) increased competition in pricing and loan structure; (cid:129) the deterioration of a borrower’s or guarantor’s financial capabilities; and (cid:129) various environmental risks, including natural disasters, which can negatively affect a borrower’s business. When underwriting C&I loans and leases, we seek to mitigate risk by using the following framework: (cid:129) considering the prospects for the borrower’s industry and the borrower’s competition; (cid:129) considering our past experience with the borrower, the collateral type, and the collectability of the collateral relative to underwritten expectations and norms; (cid:129) considering our current loan and lease portfolio concentration by loan type and collateral type; (cid:129) reviewing each loan request and renewal individually; (cid:129) using our credit committee approval process for the approval of each loan request (or aggregate credit exposure) over a certain dollar amount; and (cid:129) adhering to written loan underwriting policies and procedures including, among other factors, loan structures and covenants. Consumer Loans Consumer loans include personal loans, auto loans, home equity lines of credit, revolving lines of credit, other loans typically made by banks to individual borrowers, and purchased private student loans originated and serviced by a third-party lender. We do not currently originate first trust deed home mortgage loans. Home equity lines of credit are revolving lines of credit collateralized by junior deeds of trust on residential real estate properties. We purchase student loans that are not guaranteed by any program of the U.S. Government. These loans refinanced the outstanding student loan debt of borrowers who met certain underwriting criteria, with terms that fully amortize the debt over terms ranging from five to twenty years. Our consumer loan portfolio is subject to certain risks, including, but not limited to, the following: (cid:129) the economic conditions of the United States and the levels of unemployment; (cid:129) the amount of credit offered to consumers in the market; (cid:129) interest rate increases; (cid:129) consumer bankruptcy laws which allow consumers to discharge certain debts (excluding student loans); (cid:129) compliance with consumer lending regulations; (cid:129) additional regulations and oversight by the CFPB; and (cid:129) the ability of the sub-servicer of the Bank’s student loans to service the loans in accordance with the terms of the loan purchase agreement. We seek to mitigate the exposure to such risks through the direct approval of all internally originated consumer loans by reviewing each new loan request and each renewal individually and adhering to written credit policies. For all purchased student loans, we monitor the performance of the originator and the enforcement of our rights under the loan purchase agreement. 13 Loan Concentrations The following table presents the composition of our loan portfolio as of the dates indicated: December 31, 2016 December 31, 2015 Amount % of Total Amount % of Total (Dollars in thousands) Real estate mortgage: . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Includes PCI loans of $108.4 million and $189.0 million at December 31, 2016 and 2015, of which the majority are included in the Real Estate Mortgage category in this table. Real estate mortgage loans and real estate construction and land loans (which are predominantly commercial real estate loans) together comprised 43% and 44% of our total portfolio at December 31, 2016 and 2015. The small decline in real estate loans as a percentage of total loans was attributable to net commercial and consumer loan growth exceeding net real estate loan growth during 2016. In addition, the mix of our real estate loan portfolio shifted during 2016 as we invested in additional resources focused on multi-family and construction lending. Real estate mortgage loans declined to 37% of total loans and leases at December 31, 2016 from 41% at December 31, 2015, while real estate construction and land loans increased to 6% of total loans and leases at December 31, 2016 from 3% at December 31, 2015. Real estate mortgage loans are diversified among various property types. At December 31, 2016, our two largest property type concentrations were income producing residential property, totaling $1.2 billion or 20% of real estate mortgage loans, and healthcare property, totaling $1.0 billion or 17% of real estate mortgage loans. Income producing residential property is primarily multi-family properties but also included are portfolios of for-rent 1-4 family properties. Healthcare property types are primarily skilled nursing facilities and assisted living facilities. At December 31, 2015, income producing residential property totaled $1.0 billion or 18% of real estate mortgage loans, and healthcare property totaled $1.2 billion and comprised 21% of real estate mortgage loans. 14 Other significant real estate mortgage loan concentrations were office properties at 15% and 12% of real estate mortgage loans at December 31, 2016 and 2015, and hospitality properties at 12% and 11% of real estate mortgage loans at December 31, 2016 and 2015. Commercial loans and leases comprised 54% and 55% of our total portfolio at December 31, 2016 and 2015. Commercial loans and leases are diversified among various loan types and industries. At December 31, 2016, our largest commercial loan type concentration was cash flow loans, totaling $3.1 billion or 20% of our total portfolio compared to $3.1 billion or 21% at December 31, 2015. Other significant commercial concentrations were asset-based loans at 17% and 18% of the total portfolio at December 31, 2016 and December 31, 2015, venture capital loans at 13% and 10% of the total portfolio at December 31, 2016 and December 31, 2015, and equipment finance at 4% and 6% of the total portfolio at December 31, 2016 and December 31, 2015. At December 31, 2016, our 10 largest individual loans had outstanding balances ranging from $50.8 million to $89.7 million and in the aggregate totaled $653.6 million, or 4% of total loans and leases. Current Developments Sale and Closure of Branches In December 2016, the Bank completed the sale of two branches to First Foundation Bank. The branches were located in Laguna Hills and Seal Beach, California. The deposits of the branches totaled approximately $180 million, principally comprised of time deposits. No loans were sold in connection with the sale. In addition, the Bank will close its three branches located in the San Francisco Bay area in the first quarter of 2017. At December 31, 2016, the deposits of these branches totaled approximately $100 million. No significant one-time charges are expected to be incurred related to the closure of these branches. Stock Repurchase Program On October 17, 2016, PacWest’s Board of Directors authorized a stock repurchase program (the ‘‘Stock Repurchase Program’’), pursuant to which the Company may, from time to time, purchase shares of its common stock for an aggregate purchase price not to exceed $400 million. The common stock repurchases may be effected through open market purchases or in privately negotiated transactions, and may utilize derivatives or similar instrument to effect share repurchase transactions (including without limitation, accelerated share repurchase contracts, equity forward transactions, equity option transactions, equity swap transactions, cap transactions, collar transactions, floor transactions or other similar transactions or any combination of the foregoing transactions). The Stock Repurchase Program expires on December 31, 2017. The amount and exact timing of any repurchases will depend upon market conditions and other factors. The Stock Repurchase Program may be suspended or discontinued at any time. In the fourth quarter of 2016, the Company repurchased 652,835 shares of common stock for a total amount of $27.9 million under the Stock Repurchase Program and the repurchased shares were retired. Square 1 Financial, Inc. Acquisition PacWest acquired Square 1 on October 6, 2015. As part of the acquisition, Square 1 Bank, a wholly-owned subsidiary of Square 1, merged with and into Pacific Western. At closing, we formed the Square 1 Bank Division of Pacific Western. This division offers a comprehensive suite of financial services focused on entrepreneurial businesses and their venture capital and private equity investors nationwide. We completed this acquisition to increase our core deposits, expand our nationwide lending platform, and increase our presence in the technology and life-sciences credit markets. We recorded the 15 acquired assets and liabilities, both tangible and intangible, at their estimated fair values as of the acquisition date and increased total assets by approximately $4.6 billion. The application of the acquisition method of accounting resulted in goodwill of $446 million. CapitalSource Inc. Merger PacWest acquired CapitalSource Inc. on April 7, 2014. As part of the merger, CapitalSource Bank, a wholly-owned subsidiary of CapitalSource Inc., merged with and into Pacific Western. At closing, we formed the CapitalSource Division of the Bank. This division provides cash flow, asset-based, equipment and real estate loans and treasury management services to established middle market businesses on a national basis. We completed this acquisition in order to increase our loan and lease generation capabilities and to diversify our loan portfolio. We recorded the acquired assets and liabilities, both tangible and intangible, at their estimated fair values as of the merger date and increased total assets by approximately $10.7 billion. The application of the acquisition method of accounting resulted in goodwill of $1.5 billion. Financing We depend on deposits and external financing sources to fund our operations. We employ a variety of financing arrangements, including term debt, subordinated debt and equity. As a member of the FHLB, the Bank had secured financing capacity with the FHLB as of December 31, 2016 of $2.0 billion, collateralized by a blanket lien on $2.9 billion of certain qualifying loans not pledged to the FRBSF. The Bank also had secured financing capacity with the FRBSF of $2.2 billion as of December 31, 2016 collateralized by liens on $3.0 billion of qualifying loans. Information Technology Systems We devote significant resources to maintain stable, reliable, efficient and scalable information technology systems. Where possible, we utilize third-party software systems that are hosted and supported by nationally recognized vendors. We selectively employ proprietary software systems to support our specialty lending products. We work with our third-party vendors to monitor and maximize the efficiency of our use of their applications. We use integrated systems to originate and process loans and deposit accounts, which reduces processing time, automates numerous internal controls, improves customer experiences and reduces costs. Most customer records are maintained digitally. We also provide on-line and telephone banking services to further improve the overall client experience. We expect to migrate in-house and outsourced systems for managing customer accounts to an alternative platform hosted by a new data processing vendor with the initial phase completed during the second quarter of 2016 and the additional phases scheduled to be completed during 2017. We use an enterprise data warehouse system in order to capture, analyze and report key metrics associated with our customers and products. Data is collected across multiple systems so that standard and ad hoc reports are available to assist with managing our business. We maintain a strategic plan with respect to information technology. The information technology strategic plan outlines how specific solutions support our overall goals, analyzes infrastructure for capacity planning, details migration plans to replace aging hardware and software, provides baseline projections for allocating information technology staff, discusses information security trends and measures, considers future technologies, and provides details on information technology initiatives over the next several years. Protecting our systems to ensure the safety of our customers’ information is critical to our business. We use multiple layers of protection to control access and reduce risk, including conducting a variety of audits and vulnerability and penetration tests on our platforms, systems and applications, and maintain comprehensive incident response plans to reduce the risk that cyberattacks would be 16 successful. To protect our business operations against disasters, we have a backup offsite core processing system and comprehensive recovery plans. Risk Oversight and Management We believe risk management is another core competency of our business. We have a comprehensive risk management process that measures, monitors, evaluates and manages the risks we assume in conducting our activities. Our oversight of this risk management process is conducted by the Company’s Board of Directors (the ‘‘Board’’) and its standing committees. The committees each report to the Board and the Board has overall oversight responsibility for risk management. Our risk framework is structured to guide decisions regarding the appropriate balance between risk and return considerations in our business. Our risk framework is based upon our business strategy, risk appetite and financial plans approved by our Board. Our risk framework is supported by an enterprise risk management program. Our enterprise risk management program integrates all risk efforts under one common framework. This framework includes risk policies, procedures, measured and reported limits and targets, and reporting. Our Board approves our risk appetite statement, which sets forth the amount and type of risks we are willing to accept in pursuit of achieving our strategic, business and financial objectives. Our risk appetite statement provides the context for our risk management tools, including, among others, risk policies, delegated authorities, limits, portfolio composition, underwriting standards and operational processes. Competition The banking business is highly competitive. We compete nationwide with other commercial banks and financial services institutions for loans and leases, deposits and employees. Some of these competitors are larger in total assets and capitalization, with more offices over a wider geographic area and offer a broader range of financial services than our operations. Our most direct competition for loans comes from larger regional and national banks, diversified finance companies, venture debt funds and service-focused community banks that target the same customers as we do. 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 non-bank specialty lenders, insurance companies, private investment funds, investment banks, financial technology companies and other financial and non-financial institutions. Competition is based on a number of factors, including interest rates charged on loans and leases and paid on deposits, the scope and type of banking and financial services offered, convenience of our branch locations, customer service, technological changes and regulatory constraints. Many of our competitors are large companies that have substantial capital, technological and marketing resources. Some of our competitors have substantial market positions and have access to a lower cost of capital or a less expensive source of funds. Because of economies of scale, our larger, nationwide competitors may offer loan pricing that is more attractive that what we are able to offer. 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 is by 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 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. We differentiate ourselves in the marketplace through the quality of service we provide to borrowers while maintaining competitive interest rates, loan fees and other loan terms. We emphasize personalized relationship banking services and the efficient decision-making of our lending business 17 units. We compete effectively based on our in-depth knowledge of our borrowers’ industries and their business needs based upon information received from our borrowers’ key decision-makers, analysis by our experienced professionals and interaction between these two groups; our breadth of loan product offerings and flexible and creative approach to structuring products that meet our borrowers’ business and timing needs; and our dedication to superior client service. 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 the marketplace. Employees As of January 31, 2017, we had 1,669 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. Quantitative and Qualitative 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 Company and Bank are subject to extensive regulation under federal and state banking laws that establish a comprehensive framework for our operations. Such regulation is intended to, among other things, protect the interests of customers, including depositors, and the federal deposit insurance fund, as well as to minimize risk to the banking system as a whole. These regulations are not, however, generally charged with protecting the interests of our stockholders or creditors. Described below are elements of selected laws and regulations applicable to our Company or the Bank. 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, and they may have a material effect on the business, operations, and results of our Company or the Bank. Recent political developments, including the change in administration in the United States, have added additional uncertainty to the implementation, scope, and timing of regulatory reforms, including those related to the Dodd-Frank Act. Bank Holding Company Regulation As a bank holding company, PacWest is registered with and subject to supervision, regulation, and examination by the FRB under the BHCA, and we are required to file with the FRB periodic reports of our operations and additional information regarding the Company and its subsidiaries as the FRB may require. The Dodd-Frank Act requires the Company to act as a source of financial strength to the Bank including committing resources to support the Bank even at times when the Company may not be in a financial position to do so. Similarly, under the cross-guarantee provisions of the FDIA, 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. 18 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 the 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. Pursuant to the Bank Merger Act, the prior approval of the FDIC is required for the Bank to merge with another bank or purchase all or substantially all of the assets or assume any of the deposits of another FDIC-insured depository institution. In reviewing certain merger or acquisition transactions, the federal regulators will consider the assessment of the competitive effect and public benefits of the transactions, the capital position and managerial resources of the combined organization, the risks to the stability of the U.S. banking or financial system, our performance record under the CRA, our compliance with fair housing and other consumer protection laws, and the effectiveness of all organizations involved in combating money laundering activities. Under the BHCA, we may not engage in any business other than managing or controlling banks or furnishing services to our subsidiaries and such other activities 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 federal regulatory agencies also 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 ‘‘—Capital Requirements,’’ we are required to maintain minimum ratios of Common Equity Tier 1 capital, 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 or repurchase our shares. See ‘‘Item 5. Market for Registrant’s Common Equity and Related Shareholder 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.’’ The Dodd-Frank Act The Dodd-Frank Act, which was enacted in July 2010, significantly restructured the financial regulatory landscape in the United States, including the creation of a new systemic risk oversight body, the FSOC. The FSOC oversees and coordinates the efforts of the primary U.S. financial regulatory agencies (including the FRB, SEC, the Commodity Futures Trading Commission and the FDIC) in establishing regulations to address financial stability concerns. The Dodd-Frank Act and the FRB’s implementing regulations impose increasingly stringent regulatory requirements on financial institutions as their size and scope of activities increases. With the April 7, 2014 CapitalSource Inc. merger, our total consolidated assets exceeded $15 billion, subjecting us to additional regulatory requirements for financial institutions with over $10 billion in total consolidated assets. This substantially increased the regulations we are required to meet, particularly with respect to risk management, capital planning, and stress testing. In addition, the Company and the Bank are now subject to the examination and supervision of the CFPB. Transactions with Affiliates Transactions between the Bank and its affiliates are regulated under federal banking law. Subject to certain exceptions set forth in the Federal Reserve Act, a bank may enter into ‘‘covered transactions’’ with its affiliates if the aggregate amount of the covered transactions to any single affiliate 19 does not exceed 10 percent of the Bank’s capital stock and surplus or 20 percent of the Bank’s capital stock and surplus for covered transaction with all affiliates. Covered transactions include, among other things, extension of credit, the investment in securities, the purchase of assets, the acceptance of collateral or the issuance of a guaranty. The Dodd-Frank Act significantly expanded the coverage and scope of the limitations on affiliate transactions within a banking organization. Dividends and Share Repurchases The ability of the Company to pay dividends on or to repurchase its common stock, and the ability of the Bank to pay dividends to the Company, may be restricted due to several factors including: (a) the DGCL (in the case of the Company) and applicable California law (in the case of the Bank), (b) covenants contained in our subordinated debentures and borrowing agreements, and (c) the regulatory authority of the FRB, the DBO and the FDIC. Our ability to pay dividends to our stockholders or to repurchase shares of our common stock is subject to the restrictions set forth in the DGCL. The DGCL provides that a corporation, unless otherwise restricted by its certificate of incorporation, may declare and pay dividends (or repurchase shares) 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, the 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 cash dividends to our stockholders or to repurchase shares of our common stock may be 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 or repurchase shares of our common stock. In addition, notification to the FRB is required prior to our declaring and paying a cash dividend to our stockholders during any period in which our quarterly and/or cumulative twelve-month net earnings are insufficient to fund the dividend amount, among other requirements. 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. In connection with the decision regarding dividends and share repurchase programs, our Board of Directors will take into account general business conditions, our financial results, projected cash flows, capital requirements, contractual, legal and regulatory restrictions on the payment of dividends by the Bank to the Company and such other factors as deemed relevant. We can provide no assurance that we will continue to declare dividends on a quarterly basis or otherwise or to repurchase shares of our common stock. The declaration of dividends by the Company is subject to the discretion of our Board of Directors. 20 PacWest’s primary source of liquidity is the receipt of cash dividends from the Bank. Various statutes and regulations limit the availability of cash dividends from Pacific Western. Dividends paid by Pacific Western are regulated by the DBO and FDIC under their general supervisory authority as it relates to a bank’s capital requirements. Pacific Western may declare a dividend without the approval of the DBO and FDIC 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. Since the Bank had a retained deficit of $520.0 million at December 31, 2016, for the foreseeable future, any further cash dividends from the Bank to the Company will continue to require DBO and FDIC approval. See ‘‘Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity—Holding Company 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. Capital Requirements We are subject to the comprehensive capital framework for U.S. banking organizations known as Basel III. Basel III generally implemented the Basel Committee’s December 2010 final capital framework for strengthening international capital standards. Basel III became effective for the Company and the Bank as of January 1, 2015, subject to phase-in periods for certain of its components and other provisions. Basel III, among other things, (i) implemented increased capital levels for the Company and the Bank, (ii) introduced a new capital measure called CET1 and related regulatory capital ratio of CET1 to risk-weighted assets, (iii) specified that Tier 1 capital consists of CET1 and ‘‘Additional Tier 1 capital’’ instruments meeting certain revised requirements, (iv) mandated that most deductions/ adjustments to regulatory capital measures be made to CET1 and not to the other components of capital, and (v) expanded the scope of the deductions from and adjustments to capital as compared to existing regulations. Under Basel III, for most banking organizations the most common form of Additional Tier 1 capital is non-cumulative perpetual preferred stock and the most common form of Tier 2 capital is subordinated notes and a portion of the allowance for loan and lease losses, in each case, subject to Basel III specific requirements. Pursuant to Basel III, the minimum capital ratios are as follows: (cid:129) 4.5% CET1 to risk-weighted assets; (cid:129) 6.0% Tier 1 capital (that is, CET1 plus Additional Tier 1 capital) to risk-weighted assets; (cid:129) 8.0% Total capital (that is, Tier 1 capital plus Tier 2 capital) to risk-weighted assets; and (cid:129) 4% Tier 1 capital to average consolidated assets as reported on regulatory financial statements (known as the ‘‘leverage ratio’’). Basel III also introduced a new ‘‘capital conservation buffer’’, composed entirely of CET1, on top of the minimum risk-weighted asset ratios. 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, Tier 1 to risk-weighted assets or Total capital to risk-weighted assets above the minimum but below the capital conservation buffer will face constraints on dividends, equity repurchases and compensation based on the amount of the shortfall. The implementation of the capital conservation buffer began on January 1, 2016 at a 0.625% level and will increase by 0.625% on each subsequent January 1 until it reaches 2.5% on January 1, 2019. When fully phased-in, the Company and the Bank will be required to maintain such additional capital conservation buffer of 2.5% of CET1, effectively resulting in minimum 21 ratios of (i) CET1 to risk-weighted assets of at least 7%, (ii) Tier 1 capital to risk-weighted assets of at least 8.5%, and (iii) total capital to risk-weighted assets of at least 10.5%. Basel III provides for a number of deductions from and adjustments to CET1. These include, for example, the requirement that mortgage servicing rights, deferred tax assets arising from temporary differences that could not be realized through net operating loss carrybacks 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 items, in the aggregate, exceed 15% of CET1. Implementation of the deductions and other adjustments to CET1 commenced on January 1, 2015 and will be phased-in over a 4-year period (beginning at 40% on January 1, 2015 and an additional 20% increase per year thereafter until reaching 100%). With respect to the Bank, Basel III revised the prompt corrective action regulations as described below under ‘‘—Prompt Corrective Action’’. Basel III provides a standardized approach for risk weightings that expands the risk-weighting categories from the previous four Basel I-derived categories (0%, 20%, 50% and 100%) to a larger and more risk-sensitive number of categories, depending on the nature of the assets, generally ranging from 0% for U.S. government and agency securities, to 600% for certain equity exposures, resulting in higher risk weights for a variety of asset classes. The Company has outstanding subordinated debentures issued to trusts, which, in turn, issued trust preferred securities. The amount of subordinated debentures totaled $440.7 million at December 31, 2016. Under Basel III, none of the Company’s trust preferred securities are included in Tier 1 capital, however $428.2 million of such trust preferred securities was included in Tier 2 capital at December 31, 2016. We believe that, as of December 31, 2016, the Company and the Bank met all capital adequacy requirements under Basel III. See ‘‘Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Regulatory Matters—Capital’’ for further information on regulatory capital requirements, capital ratios, and deferred tax asset limits as of December 31, 2016 for the Company and the Bank. Stress Testing As an institution with total assets in excess of $10 billion, the stress testing rules of the FRB and the FDIC require the Company and the Bank to conduct an annual company-run stress test of capital, consolidated earnings and losses under one base scenario and at least two supervisory stress scenarios provided by the federal bank regulators. Stress test results must be reported to the regulatory agencies, and the stress testing rules require the public disclosure of a summary of the stress test results. The Company’s and Bank’s capital ratios reflected in the stress test calculations are an important factor considered by the FRB and FDIC in evaluating the capital adequacy of the Company and the Bank and whether any proposed payments of dividends or stock repurchases may be deemed an unsafe or unsound practice. Prompt Corrective Action 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. A bank’s category is determined solely for the purpose of applying prompt corrective action regulations, and the capital category may not constitute an accurate representation of the bank’s overall financial condition or prospects for other purposes. 22 In addition to measures taken under the prompt corrective action provisions, the Bank may be subject to potential enforcement actions by the federal or state banking agencies for unsafe or unsound practices in conducting its business 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, and 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. Safety and Soundness Standards As required by the FDIA, guidelines adopted by the federal bank regulatory agencies establish general standards relating to internal controls and information systems, internal audit systems, loan documentation, credit underwriting, interest rate exposure, asset growth and quality, and compensation, fees and benefits. Bank holding companies with total consolidated assets of $10 billion or more are required to establish and maintain risk management committees for their boards of directors to oversee the bank holding companies’ risk management framework. Deposit Insurance The Bank is a state-chartered, ‘‘non-member’’ bank regulated by the DBO and the FDIC. Pacific Western accepts deposits, and those deposits have the benefit of FDIC insurance up to the applicable limits. The applicable limit for FDIC insurance for most types of accounts is $250,000. Under the FDIC’s risk-based deposit premium assessment system, the assessment rates for an insured depository institution are determined by an assessment rate calculator, which is based on a number of elements that measure the risk each institution poses to the Deposit Insurance Fund. The calculated assessment rate is applied to average consolidated assets less the average tangible equity of the insured depository institution during the assessment period to determine the dollar amount of the quarterly assessment. Under the current system, premiums are assessed quarterly and could increase if, for example, criticized loans and leases and/or other higher risk assets increase or balance sheet liquidity decreases. In 2010, the FDIC adopted its Deposit Insurance Fund restoration plan to ensure that the fund reserve ratio reaches 1.35% of total deposits by September 30, 2020, and the FDIC’s final rule with respect to this became effective July 1, 2016. Insured institutions with assets over $10 billion, such as the Bank, are responsible for funding the increase. For the year ended December 31, 2016, we incurred $14.0 million of FDIC assessment expense. Under the FDIA, the FDIC may terminate deposit insurance upon a finding that the institution has engaged in unsafe and unsound practices, is in an unsafe or unsound condition to continue operations, or has violated any applicable law, regulation, rule, order or condition imposed by the FDIC. Incentive Compensation In 2010, federal banking regulators issued final joint agency guidance on Sound Incentive Compensation Policies. This guidance applies to executive and non-executive incentive plans administered by the Bank. The guidance notes that incentive compensation programs must (i) provide employees incentives that appropriately balance risk and reward, (ii) be compatible with effective controls and risk management and (iii) be supported by strong corporate governance, including 23 oversight by the board. The FRB reviews, as part of its regular examination process, the Company’s incentive compensation programs. In addition, the Dodd-Frank Act requires the federal bank regulatory agencies and the SEC to establish joint regulations or guidelines prohibiting incentive based payment arrangements at specified regulated entities having at least $1 billion in total assets, such as the Company and the Bank, that encourage inappropriate risks by providing an executive officer, employee, director or principal stockholder with excessive compensation, fees, or benefits that could lead to material financial loss to the entity. In addition, these regulators must establish regulations or guidelines requiring enhanced disclosure of incentive based compensation arrangements to regulators. The agencies proposed initial regulations in April 2011 and proposed revised regulations during the second quarter of 2016 that would establish general qualitative requirements applicable to all covered entities (and additional specific requirements for entities with total consolidated assets of at least $50 billion). The general qualitative requirements include (i) prohibiting incentive arrangements that encourage inappropriate risks by providing excessive compensation; (ii) prohibiting incentive arrangements that encourage inappropriate risks that could lead to a material financial loss; (iii) establishing requirements for performance measures to appropriately balance risk and reward; (iv) requiring board of director oversight of incentive arrangements; and (v) mandating appropriate record-keeping. Consumer Regulation We are subject to a number of federal and state consumer protection laws that extensively govern our relationship with our customers. These laws include the Equal Credit Opportunity Act, the Fair Credit Reporting Act, the Truth in Lending Act, the Truth in Savings Act, the Electronic Fund Transfer Act, the Expedited Funds Availability Act, the Home Mortgage Disclosure Act, the Fair Housing Act, the Real Estate Settlement Procedures Act, the Fair Debt Collection Practices Act, the Service Members Civil Relief Act and these laws’ respective state-law counterparts, as well as state usury laws and laws regarding unfair and deceptive acts and practices. Violations of applicable consumer protection laws can result in significant potential liability from litigation brought by customers, including actual damages, restitution and attorneys’ fees. Federal bank regulators, state attorneys general and state and local consumer protection agencies may also seek to enforce consumer protection requirements and obtain these and other remedies, including regulatory sanctions, customer rescission rights, action by the state and local attorneys general in each jurisdiction in which we operate and civil money penalties. Failure to comply with consumer protection regulations may also result in our failure to obtain any required bank regulatory approval for merger or acquisition transactions we may wish to pursue or our prohibition from engaging in such transactions even if approval is not required. The CFPB has broad rulemaking, supervisory and enforcement powers under various federal consumer financial protection laws. The CFPB is also authorized to engage in consumer financial education, track consumer complaints, request data and promote the availability of financial services to underserved consumers and communities. The Bank is subject to direct oversight and examination by the CFPB. The CFPB has broad supervisory, examination, and enforcement authority over various consumer financial products and services, including the ability to require reimbursements and other payments to customers for alleged legal violations and to impose significant penalties, as well as injunctive relief that prohibits lenders from engaging in allegedly unlawful practices. The CFPB also has the authority to obtain cease and desist orders providing for affirmative relief or monetary penalties. State regulation of financial products and potential enforcement actions could also adversely affect our business, financial condition or results of operations. 24 Depositor Preference The FDIA 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. USA PATRIOT Act and Anti-Money Laundering 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 the Company and the Bank 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 and prospective 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 a bank holding company acquisition and/or a bank merger act application. We regularly evaluate and continue to enhance our systems and procedures to continue to comply with the PATRIOT Act and other anti-money laundering initiatives. 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, strategic, and reputational consequences for the institution and result in material fines and sanctions. Office of Foreign Assets Control Regulation The United States has imposed economic sanctions that affect transactions with designated foreign countries, designated nationals and others. These rules are based on their administration by OFAC. The OFAC-administered sanctions targeting designated 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, strategic, and reputational consequences, and result in civil money penalties on the Company and the Bank. Community Reinvestment Act The CRA generally requires the Bank to identify the communities it serves and to make loans and investments, offer products, make donations in, and provide services designed to meet the credit needs of these communities. The CRA also requires the Bank to maintain comprehensive records of its CRA activities to demonstrate how we are meeting the credit needs of our communities. These documents are subject to periodic examination by the FDIC. During these examinations, the FDIC rates such 25 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 all of the communities served, including low-and moderate-income neighborhoods, in determining such rating. Failure of an institution 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. In the case of a bank holding company, such as the Company, when applying to acquire a bank, savings association, or a bank holding company, the FRB will assess the CRA record of each depository institution of the applicant bank holding company in considering the application. Customer Information Security The FRB and other bank regulatory agencies have adopted guidelines for safeguarding confidential, personal, non-public 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 these 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 non-public personal information about consumers to non-affiliated third parties. In general, the statutes require disclosures to consumers on policies and procedures regarding the disclosure of such non-public personal information and, except as otherwise required by law, prohibit disclosing such information except as provided in the Bank’s policies and procedures. We have implemented privacy policies addressing these restrictions, which are distributed regularly to all existing and new customers of the Bank. 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, or that serve as collateral for our loans, 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 presently aware of any actual liability for hazardous waste contamination that would be reasonably likely to have a material adverse effect on the Company as of February 20, 2017. 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. Regulation of Certain Subsidiaries Our subsidiary, S1AM is registered with the SEC under the Investment Advisers Act of 1940, as amended, and is subject to its rules and regulations. Following the completion of various studies on investment advisers and broker-dealers required by the Dodd-Frank Act, the SEC has, among other things, recommended to Congress that it consider various means to enhance the SEC’s examination authority over investment advisers, which may have an impact on S1AM that we cannot currently assess. 26 ITEM 1A. RISK FACTORS In the course of conducting our business operations, we are exposed to a variety of risks, some of which are inherent in the financial services industry and others of which are more specific to our own businesses. The discussion below addresses the most significant factors, of which we are currently aware, that could affect our businesses, results of operations and financial condition. Additional factors that could affect our businesses, results of operations and financial condition are discussed in ‘‘Item 1. Business—Forward-Looking Information.’’ However, other factors not discussed below or elsewhere in this Annual Report on Form 10-K could adversely affect our businesses, results of operations and financial condition. Therefore, the risk factors below should not be considered a complete list of potential risks we may face. Any risk factor described in this Annual Report on Form 10-K or in any of our other SEC filings could by itself, or together with other factors, materially adversely affect our liquidity, cash flows, competitive position, business, reputation, results of operations, capital position or financial condition, including materially increasing our expenses or decreasing our revenues, which could result in material losses. Our business is adversely affected by unfavorable economic and market conditions. General Economic and Market Conditions Risk U.S. economic conditions affect our operating results. The United States economy has been in a slow-paced seven-year expansion since the Great Recession ended in 2009. This current expansion has been longer than most U.S. expansionary periods in recent history, increasing the probability of a near-term U.S. economic recession. An economic recession adversely affects our operating results because we experience higher loan and lease charge-offs and higher operating costs. Global economic conditions also affect our operating results because global economic conditions directly influence the U.S. economic conditions. Various market conditions also affect our operating results. Real estate market conditions directly affect performance of our loans secured by real estate. Debt markets affect the availability of credit which impacts the rates and terms at which we offer loans and leases. Stock market downturns affect businesses’ ability to raise capital and invest in business expansion. Stock market downturns often signal broader economic deterioration and/or a downward trend in business earnings which adversely affects businesses’ ability to service their debts. An economic recession or a downturn in various markets could have one or more of the following adverse effects on our business: (cid:129) a decrease in the demand for our loans and leases and other products and services offered by us; (cid:129) a decrease in our deposit balances due to overall reductions in the accounts of customers; (cid:129) a decrease in the value of our loans and leases; (cid:129) an increase in the level of nonperforming and classified loans and leases: (cid:129) an increase in provisions for credit losses and loan and lease charge-offs; (cid:129) a decrease in net interest income derived from our lending and deposit gathering activities; (cid:129) a decrease in the Company’s stock price; (cid:129) an impairment of goodwill or certain intangible assets; or (cid:129) an increase in our operating expenses associated with attending to the effects of the above-listed circumstances. 27 Public equity offerings and mergers and acquisitions involving our Square 1 Bank Division clients or a slowdown in venture capital investment levels may reduce the market for venture capital investment and the borrowing needs of our current and potential clients, which could adversely affect our business, results of operations, or financial condition. Our Square 1 Bank Division’s strategy is focused on providing banking products and services to entrepreneurial businesses, including in particular early- and expansion-stage companies that receive financial support from sophisticated investors, including venture capital or private equity firms, and corporate investors. We derive a meaningful share of deposits from these companies and provide them with loans as well as other banking products and services. In many cases, our credit decisions are based on our analysis of the likelihood that our venture capital-backed client will receive additional rounds of equity capital from investors. If the amount of capital available to such companies decreases, it is likely that the number of new clients and investor financial support to our existing borrowers would decrease, which could have a material adverse effect on the loan and deposit growth prospects of the Square 1 Bank Division. Our ability to attract and retain qualified employees is critical to our success. Our employees are our most important resource, and in many areas of the financial services industry, competition for qualified personnel is intense. We endeavor to attract talented and diverse new employees and retain and motivate our existing employees. We also seek to retain proven, experienced senior employees with superior talent, augmented from time to time by external hires, to provide continuity of succession of our executive management team. In addition, the Company’s Board of Directors oversees succession planning, including review of the succession plans for the Chief Executive Officer and other members of executive management. If for any reason we are unable to continue to attract or retain qualified employees, our performance, including our competitive position, could be materially and adversely affected. Credit Risk Credit Risk is the Risk of Loss Arising from the Inability or Failure of a Borrower or Counterparty to Meet its Obligation. We may not recover all amounts that are contractually owed to us by our borrowers. We are dependent on loan and lease principal, interest, and fee collections to partially fund our operations. A shortfall in collections and proceeds may impair our ability to fund our operations or to repay our existing debt. When we loan money, commit to loan money or enter into a letter of credit or other contract with a counterparty, we incur credit risk. The credit quality of our portfolio can have a significant impact on our earnings. We expect to experience charge-offs and delinquencies on our loans and leases in the future. Our clients’ actual operating results may be worse than our underwriting indicated when we originated the loans and leases, and in these circumstances, if timely corrective actions are not taken, we could incur substantial impairment or loss of the value on these loans and leases. We may fail to identify problems because our client did not report them in a timely manner or, even if the client did report the problem, we may fail to address it quickly enough or at all. Even if clients provide us with full and accurate disclosure of all material information concerning their businesses, we may misinterpret or incorrectly analyze this information. Mistakes may cause us to make loans and leases that we otherwise would not have made or to fund advances that we otherwise would not have funded, either of which could result in losses on loans and leases, or necessitate that we significantly increase our allowance for loan and lease losses. As a result, we could suffer loan losses and have nonperforming loans and leases, which could have a material adverse effect on our net earnings and results of operations and financial condition, to the extent the losses exceed our allowance for loan and lease losses. 28 Additionally, some of our loans and leases are secured by a lien on specified collateral of the client and we may not obtain or properly perfect our liens or the value of the collateral securing any particular loan may not protect us from suffering a partial or complete loss if the loan becomes nonperforming and we proceed to foreclose on or repossess the collateral. In such event, we could suffer loan losses, which could have a material adverse effect on our net earnings, allowance for loan and lease losses, financial condition, and results of operations. Our allowance for credit losses may not be adequate to cover actual losses. In accordance with generally accepted accounting principles in the United States, we maintain an allowance for loan and lease losses to provide for loan and lease 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 absorb 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 inherent 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 leases and allowance for credit losses. While we believe our allowance for credit losses is appropriate for the risk identified in our loan and lease portfolio, we cannot provide assurance 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 financial condition and results of operations. See ‘‘Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations’’ for more information. Our concentration of loans and leases to privately owned small and medium-sized companies and our concentration of lending to particular market sectors and industries could expose us to greater lending risk if the privately owned small or medium-sized company, market sector or industry were to experience economic difficulties or changes in the regulatory environment. Our portfolio consists primarily of real estate and commercial loans and leases to small and medium-sized privately owned businesses in a limited number of industries throughout the United States. Loan and leases made to these types of clients entail higher risks than loans and leases made to larger, publicly owned firms that are able to access a broader array of credit sources and thus more easily weather an economic downturn. Commercial loans and leases comprised 54% of our total portfolio at December 31, 2016. At December 31, 2016, our largest commercial loan type concentration was cash flow loans, which includes leveraged loans as defined by regulatory guidance, totaling 20% of our portfolio. Cash flow loans are provided to sophisticated buyers and private equity groups, financial investors, strategic companies and sponsors to finance the acquisition or recapitalization of a business. Other significant commercial concentrations by loan type include asset-based loans at 17%, venture capital loans at 13%, and equipment finance at 4% of the total portfolio at December 31, 2016. As of December 31, 2016, real estate mortgage loans and real estate construction and land loans (which are predominantly commercial real estate mortgage loans) together comprised 43% of our total portfolio and our largest property type concentration was multi-family properties, totaling 18% of real estate mortgage loans. Other significant real estate mortgage loan property type concentrations were healthcare property at 17% and office properties at 15% at December 31, 2016. In addition, 49% of our loans secured by real estate were in California at December 31, 2016. If any particular industry or market sector were to experience economic difficulties, the overall timing and amount of collections on our loans to clients operating in those industries may differ from 29 what we expected, which could have a material adverse impact on our financial condition or results of operations. Market Risk Market Risk is the Risk that Market Conditions May Adversely Impact the Value of Assets or Liabilities or Otherwise Negatively Impact Earnings. Market Risk is Inherent to the Financial Instruments Associated with our Operations, Including Loans, Deposits, Securities, Short-term Borrowings, Long-term Debt, and Derivatives. 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 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. Following an increase in 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. Accordingly, changes in levels of interest rates could materially and adversely affect our net interest spread, net interest margin, cost of deposits, asset quality, loan origination volume, liquidity, and overall profitability. The price of our common stock may be volatile or may decline. The trading price of our common stock may fluctuate as a result of a number of factors, many of which are outside our control. In addition, the stock market is subject to fluctuations in the share prices and trading volumes that affect the market prices of the shares of many companies. These broad market fluctuations could adversely affect the market price of our common stock. Among the factors that could affect our stock price are: (cid:129) actual or anticipated quarterly fluctuations in our periodic operating results and financial condition; (cid:129) changes in revenue or earnings estimates or publication of research reports and recommendations by financial analysts; (cid:129) failure to meet analysts’ revenue or earnings estimates; (cid:129) cyber security breaches; (cid:129) speculation in the press or investment community; 30 (cid:129) strategic actions by us or our competitors, such as acquisitions or restructurings; (cid:129) actions by institutional stockholders; (cid:129) fluctuations in the stock price and operating results of our competitors; (cid:129) general market conditions and, in particular, developments related to market conditions for the financial services industry; (cid:129) proposed or adopted regulatory changes or developments; (cid:129) anticipated or pending investigations, proceedings or litigation that involve or affect us; or (cid:129) domestic and international economic factors unrelated to our performance. The stock market and, in particular, the market for financial institution stocks, has experienced significant volatility during the past several years and the future performance of the stock market is inherently uncertain. As a result, the stock market generally and the market price and trading volume of our common stock specifically may be volatile. The trading price of our common stock will depend on many factors, which may change from time to time, including, without limitation, our financial condition, performance, creditworthiness and prospects, and future sales of our equity or equity-related securities. A significant decline in our stock price could result in the potential impairment of goodwill, substantial losses for individual stockholders and could lead to costly and disruptive securities litigation. The value of our securities in our investment portfolio may decline in the future. The fair value of our investment securities may be adversely affected by market conditions, including changes in interest rates, implied credit spreads, and the occurrence of any events adversely affecting the issuer of particular securities in our investments portfolio. We analyze our securities on a quarterly basis to determine if an other-than-temporary impairment has occurred. The process for determining whether impairment is other-than-temporary usually requires complex, subjective judgments about the future financial performance of the issuer in order to assess the probability of receiving all contractual principal and interest payments on the security. Because of changing economic and market conditions affecting issuers, we may be required to recognize other-than-temporary impairment in future periods, which could have a material adverse effect on our business, financial condition, or results of operations. Liquidity Risk Liquidity Risk is the Potential Inability to Meet our Contractual and Contingent Financial Obligations, On- or Off-balance Sheet, as they Become Due. We are subject to liquidity risk, which could adversely affect our financial condition and results of operations. Effective liquidity management is essential for the operation of our business. Although we have implemented strategies to maintain sufficient and diverse sources of funding to accommodate planned, as well as unanticipated, changes in assets, liabilities, and off-balance sheet commitments under various economic conditions, an inability to raise funds through deposits, borrowings, the sale of investment securities and other sources could have a material adverse effect on our liquidity. Our access to funding sources in amounts adequate to finance our activities could be impaired by factors that affect us specifically or the financial services industry in general. Factors that could detrimentally impact our access to liquidity sources include a decrease in the level of our business activity due to a market disruption, a decrease in the borrowing capacity assigned to our pledged assets by our secured creditors, or adverse regulatory action against us. Our ability to acquire deposits or borrow could also be impaired by factors that are not specific to us, such as a severe disruption of the financial markets or negative views and expectations about the prospects for the financial services industry generally as a result of conditions faced by banking organizations in the domestic and worldwide credit markets. 31 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, regulatory requirements, 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. Deterioration in 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, inter-bank borrowings, repurchase agreements and borrowings from the discount window of the FRBSF, as well as to capital markets. We cannot provide any assurance 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 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. Further, if we need to raise capital in the future, we may have to do so when many other financial institutions are also seeking to raise capital and would then have to compete with those institutions for investors. An inability to raise additional capital on acceptable terms when needed could have a materially adverse effect on our business, financial condition, or results of operations. We may be adversely affected by changes in the actual or perceived soundness or condition of other financial institutions. Our ability to engage in routine funding transactions could be adversely affected by the actions and commercial and financial soundness of other financial institutions. Financial institutions are closely related as a result of trading, investment, liquidity management, clearing, counterparty and other relationships. Loss of public confidence in any one institution, including through default, could lead to liquidity and credit problems, losses, or defaults for other institutions. Even the perceived lack of creditworthiness of, or questions about, a counterparty may lead to market-wide liquidity and credit problems, losses, or defaults by various institutions. This systemic risk may adversely affect financial intermediaries, such as clearing agencies, banks and exchanges we interact with on a daily basis or key funding providers such as the Federal Home Loan Banks, any of which could have a material adverse effect on our access to liquidity or otherwise have a material adverse effect on our business, financial condition, or results of operations. The primary source of the holding company’s liquidity from which, among other things, we pay dividends is the receipt of dividends from the Bank. The holding company, PacWest, is 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 DBO could assert that payment of dividends or other payments is an unsafe or unsound practice. In the event the Bank is unable to pay dividends to the holding company, it is likely that we, in turn, would have to discontinue capital distributions in the form of dividends or share repurchases and may have difficulty meeting our other financial obligations, including payments in respect of any outstanding indebtedness or subordinated debentures. Since the Bank had an accumulated deficit of $520.0 million at December 31, 2016, for the foreseeable future, any cash dividends from the Bank to the holding company will continue to require DBO and FDIC approval. The inability of the Bank to pay dividends to the holding company could have a material adverse effect on our business, including the market price of our common stock. 32 We may reduce or discontinue the payment of 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 the FRB, and by certain covenants contained in our subordinated debentures. 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 and/or cumulative twelve-month net earnings are insufficient to fund the dividend amount, among other requirements. We may not pay a dividend if the FRB objects or until such time as we receive approval from the FRB or we no longer need to provide notice under applicable regulations. In addition, we may be restricted by applicable law or regulation or actions taken by our regulators, now or in the future, from paying dividends to our stockholders. We cannot provide assurance that we will continue paying dividends on our common stock at current levels or at all. A reduction or discontinuance of dividends on our common stock could have a material adverse effect on our business, including the market price of our common stock. Regulatory, Compliance and Legal Risk We are subject to extensive regulation, which could materially and adversely affect our business. The banking industry is extensively regulated and supervised under both federal and state laws and regulations that are intended primarily for the protection of depositors, customers, federal deposit insurance funds and the banking system as a whole, not for the protection of our stockholders and creditors. The Company is subject to regulation and supervision by the FRB, and the Bank is subject to regulation and supervision by the FDIC, DBO and CFPB. The laws and regulations applicable to us govern a variety of matters, including, but not limited to, permissible types, amounts and terms of loans and investments we make, the maximum interest rate that may be charged, consumer disclosures on the products and services we offer, the amount of reserves we must hold against our customers’ deposits, the types of deposits we may accept and the rates we may pay on such deposits, maintenance of adequate capital and liquidity, restrictions on dividends and establishment of new offices by the Bank. We must obtain approval from our regulators before engaging in certain activities, including certain acquisitions, and there can be no assurance that any regulatory approvals we may require will be obtained, or obtained without conditions, either in a timely manner or at all. Our regulators have the ability to compel us to, or restrict us from, taking certain actions entirely, such as actions that our regulators deem to constitute unsafe or unsound banking practice. While we have policies and procedures designed to prevent violations of the extensive federal and state regulations we are subject to, our failure to comply with any applicable laws or regulations, or regulatory policies and interpretations of such laws and regulations, could result in orders from our regulators, civil monetary penalties, or damage to our reputation, all of which could have a material adverse effect on our business, financial condition, or results of operation. 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 any future specific government stabilization programs may subject us to additional restrictions. There can be no assurance that laws, rules and regulations will not be proposed or 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. While the change in administration in the United States may ultimately roll back or modify certain of the regulations adopted since the financial crisis, including 33 those adopted under the Dodd-Frank Act, uncertainty about the timing and scope of any such changes as well as the cost of complying with a new regulatory regime, may negatively impact our business, at least in the short term, even if the long-term impact of any such changes are positive for our business. In October 2012, as required by the Dodd-Frank Act, the FRB and FDIC published final rules regarding company-run stress testing. As a result of these final rules we invest a significant amount of time and resources into conducting an annual company-run stress test of capital, consolidated earnings and losses under various stress scenarios provided by our regulators. Our stress test results are considered by the FRB and FDIC in evaluating our capital adequacy and could have a negative impact on our ability to make capital distributions in the form of dividends or share repurchases. We are subject to capital adequacy standards, and a failure to meet these standards could adversely affect our financial condition. The Company and the Bank are each subject to capital adequacy and liquidity rules and other regulatory requirements specifying minimum amounts and types of capital that must be maintained. From time to time, the regulators implement changes to these regulatory capital adequacy and liquidity guidelines. If we fail to meet these minimum capital and liquidity guidelines and other regulatory requirements, we or our subsidiaries may be restricted in the types of activities we may conduct and may be prohibited from taking certain capital actions, such as paying dividends and repurchasing or redeeming capital securities. The Company and its subsidiaries are subject to changes in federal and state tax laws, interpretation of existing laws and examinations and challenges by taxing authorities. Our financial performance is impacted by federal and state tax laws. Given the current economic and political environment, and ongoing budgetary pressures, the enactment of new federal or state tax legislation may occur or interpretations of existing tax laws could change. The enactment of such legislation, or changes in the interpretation of existing law, including provisions impacting income tax rates, apportionment, consolidation or combination, income, expenses, and credits, may have a material adverse effect on our financial condition, results of operations, and liquidity. In the normal course of business, we are routinely subjected to examinations and audits from federal and state taxing authorities regarding tax positions taken by us and the determination of the amount of tax due. These examinations may relate to income, franchise, gross receipts, payroll, property, sales and use, or other tax returns filed, or not filed, by us. The challenges made by taxing authorities may result in adjustments to the amount of taxes due, and may result in the imposition of penalties and interest. If any such challenges are not resolved in our favor, they could have a material adverse effect on our financial condition, results of operations, and liquidity. We are subject to claims and litigation which could adversely affect our cash flows, financial condition and results of operations, or cause us significant reputational harm. We and certain of our directors, officers and subsidiaries may be involved, from time to time, in reviews, investigations, litigation, and other proceedings pertaining to our business activities. If claims or legal actions, whether founded or unfounded, are not resolved in a favorable manner to us, they may result in significant financial liability. Although we establish accruals for legal matters when and as required by generally accepted accounting principles and certain expenses and liabilities in connection with such matters may be covered by insurance, the amount of loss ultimately incurred in relation to those matters may be substantially higher than the amounts accrued and/or insured. Substantial legal liability could adversely affect our business, financial condition, results of operations, and reputation. 34 Risk of the Competitive Environment in which We Operate We face strong competition from financial services companies and other companies that offer banking services, which could materially and adversely affect our business. The financial services industry has become even more competitive as a result of legislative, regulatory and technological changes and continued banking consolidation, which may increase in connection with current economic, market and political conditions. We face substantial competition in all phases of our operations from a variety of competitors, including national banks, regional banks, community banks and, more recently, financial technology (or ‘‘fintech’’) companies. Many of our competitors offer the same banking services that we offer and our success depends on our ability to adapt our products and services to evolving industry standards. Increased competition in our market may result in reduced new loan and lease production and/or decreased deposit balances or less favorable terms on loans and leases and/or deposit accounts. We also face competition from many other types of financial institutions, including without limitation, non-bank specialty lenders, insurance companies, private investment funds, investment banks, and other financial intermediaries. While there are a limited number of direct competitors in the venture banking market, some of our competitors have long-standing relationships with venture firms and the companies that are funded by such firms. The market for our Square 1 Bank Division is extremely competitive and several of our competitors have significantly greater resources, established customer bases, more locations, and longer operating histories. We also face competition from 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 as a result. Ultimately, we may not be able to compete successfully against current and future competitors. Our ability to maintain, attract and retain customer relationships and investors is highly dependent on our reputation. Damage to our reputation could undermine the confidence of our current and potential customers and investors in our ability to provide high-quality financial services. Such damage could also impair the confidence of our counterparties and vendors and ultimately affect our ability to effect transactions. Maintenance of our reputation depends not only on our success in maintaining our service-focused culture and controlling and mitigating the various risks described herein, but also on our success in identifying and appropriately addressing issues that may arise in areas such as potential conflicts of interest, anti-money laundering, client personal information and privacy issues, customer and other third-party fraud, record-keeping, technology-related issues including but not limited to cyber fraud, regulatory investigations and any litigation that may arise from the failure or perceived failure to comply with legal and regulatory requirements. Maintaining our reputation also depends on our ability to successfully prevent third parties from infringing on our brands and associated trademarks and our other intellectual property. Defense of our reputation, trademarks and other intellectual property, including through litigation, could result in costs that could have a material adverse effect on our business, financial condition, or results of operations. 35 Risks Related to Risk Management Failure to keep pace with technological change could adversely affect our business and we recently converted to a new core processing system. The financial services industry experiences continuous technological change with frequent introductions of new technology-driven products and services. The effective use of technology increases efficiency and enables financial institutions to better serve customers and to reduce costs. Our future success depends, in part, upon our ability to address the needs of our customers by using technology to provide products and services that will satisfy customer demands, as well as to create additional efficiencies in our operations. To keep pace with technology and provide sufficient scalability for growth, we completed the second phase of our conversion to a new core processing system related to managing customer accounts in January 2017 and the additional phases are scheduled to be completed during 2017. Many of our competitors, however, have substantially greater resources to invest in technological improvements. We may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to our customers. In addition, we depend on internal and outsourced technology to support all aspects of our business operations. Interruption or failure of these systems creates a risk of business loss as a result of adverse customer experiences and possible diminishing of our reputation, damage claims or civil fines. Failure to successfully keep pace with technological change affecting the financial services industry or to successfully convert to a new core processing system could have a material adverse impact on our business and, in turn, our financial condition and results of operations. Our acquisitions may subject us to unknown risks. 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 deterioration in the credit quality of the acquired loans; 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 increased costs or give assurances that our due diligence or mitigation efforts will be sufficient to protect against any such loss or increased costs. Our ability to execute strategic activities successfully will depend on a variety of factors. These factors likely will vary based on the nature of the activity but may include our success in integrating the operations, services, products, personnel and systems of an acquired company into our business, operating effectively with any partner with whom we elect to do business, retaining key employees, achieving anticipated synergies, meeting expectations and otherwise realizing the undertaking’s anticipated benefits. Our ability to address these matters successfully cannot be assured. In addition, our strategic initiatives may divert resources or management’s attention from ongoing business operations and may subject us to additional regulatory scrutiny. If we do not successfully execute a strategic undertaking, it could adversely affect our business, financial condition, results of operations, reputation, regulatory relationships and growth prospects. In addition, if we determined that the value of an acquired business had decreased and that the related goodwill is impaired, an impairment of goodwill charge to earnings would be recognized. To the extent we issue capital stock in connection with future acquisitions, these transactions may be dilutive to book value and earnings per share and will dilute share ownership. 36 A breach in the security of our systems, or those of contracted partners, could disrupt our business, result in the disclosure of confidential information, damage our reputation, and create significant financial and legal exposure. Although we devote significant resources to maintain and regularly update our systems and processes that are designed to protect the security of our computer systems, software, networks and other technology assets, as well as the confidentiality, integrity and availability of information belonging to us and our customers, there is no assurance that all of our security measures will provide absolute security. Many financial institutions, including PacWest, have been subjected to attempts to infiltrate the security of their websites or other systems, some involving sophisticated and targeted attacks intended to obtain unauthorized access to confidential information, destroy data, disrupt or degrade service, sabotage systems or cause other damage, including through the introduction of computer viruses or malware, cyberattacks and other means. We have been targeted by individuals and groups using malicious code and viruses, and have experienced distributed denial-of-service attacks with the objective of disrupting on-line banking services and expect to be subject to such attacks in the future. Despite efforts to ensure the integrity of our systems, it is possible that we may not be able to anticipate, detect or recognize threats to our systems or to implement effective preventive measures against all security breaches of these types inside or outside our business, especially because the techniques used change frequently or are not recognized until launched, and because cyberattacks can originate from a wide variety of sources, including individuals or groups who are associated with external service providers or who are or may be involved in organized crime or linked to terrorist organizations or hostile foreign governments. Those parties may also attempt to fraudulently induce employees, customers, third-party service providers or other users of our systems to disclose sensitive information in order to gain access to our data or that of our customers or clients. These risks may increase in the future as our web-based product offerings grow or we expand internal usage of web-based applications. A successful penetration or circumvention of the security of our systems or the systems of another market participant could cause serious negative consequences, including significant disruption of our operations, misappropriation of confidential information, or damage to computers or systems, and may result in violations of applicable privacy and other laws, financial loss, loss of confidence in our security measures, customer dissatisfaction, significant litigation exposure and harm to our reputation, all of which could have a material adverse effect on our business, financial condition, results of operations, and future prospects. We rely on other companies to provide key components of our business infrastructure. We rely on certain third parties to provide products and services necessary to maintain day-to-day operations, such as data processing and storage, recording and monitoring transactions, on-line banking interfaces and services, Internet connections and network access. Even though we have a vendor management program to help us carefully select and monitor the performance of third parties, we do not control their actions. The failure of a third-party to perform in accordance with the contracted arrangements under service level agreements as a result of changes in the third party’s organizational structure, financial condition, support for existing products and services, strategic focus, system interruption or breaches, or for any other reason, could be disruptive to our operations, which could have a material adverse effect on our business, financial condition and results of operations. Replacing these third parties could also create significant delays and expense. Accordingly, use of such third parties creates an inherent risk to our business operations. 37 Our controls and procedures may fail or be circumvented. We regularly review and update our internal controls, disclosure controls and procedures, compliance monitoring activities and corporate governance policies and procedures. Any system of controls, however well-designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. Any failure or circumvention of our controls and procedures or failure to comply with regulations related to controls and procedures could have a material adverse effect on our business, results of operations, reputation and financial condition. In addition, if we identify material weaknesses in our internal control over financial reporting or are required to restate our financial statements, we could be required to implement expensive and time-consuming remedial measures. We could lose investor confidence in the accuracy and completeness of our financial reports and potentially subject us to litigation. Any material weaknesses in our internal control over financial reporting or restatement of our financial statements could have a material adverse effect on our business, results of operations, reputation, and financial condition. Severe weather, natural disasters, acts of war or terrorism or other adverse external events could harm the Company’s business. Severe weather, natural disasters, acts of war or terrorism and other adverse external events could have a significant impact on our ability to conduct business. The nature and level of severe weather and/or natural disasters cannot be predicted and may be exacerbated by global climate change. Severe weather and natural disasters could harm our operations through interference with communications, including the interruption or loss of our computer systems, which could prevent or impede us from gathering deposits, originating loans and processing and controlling the flow of business, as well as through the destruction of facilities and our operational, financial and management information systems. California, in which a substantial portion of our business is located and a substantial portion of our loan collateral is located, is susceptible to severe weather and natural disasters such as earthquakes, floods, droughts and wildfires. Additionally, the United States remains a target for potential acts of war or terrorism. Such severe weather, natural disasters, acts of war or terrorism or other adverse external events could negatively impact our business operations or the stability of our deposit base, cause significant property damage, adversely impact the values of collateral securing our loans and/or interrupt our borrowers’ abilities to conduct their business in a manner to support their debt obligations, which could result in losses and increased provisions for credit losses. There is no assurance that our business continuity and disaster recovery program can adequately mitigate the risks of such business disruptions and interruptions. Risk from Accounting Estimates Our decisions regarding the fair value of assets acquired could be inaccurate which could materially and adversely affect our business, financial condition, results of operations, and future prospects. To comply with generally accepted accounting principles, management must exercise judgment in selecting, determining, and applying accounting methods, assumptions, and estimates. Management makes various estimates and judgments about the collectability of 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. If the actual performance of the acquired loans and/or the value of the collateral differs materially from management’s estimates, any resulting losses or increased credit loss provisions could have a negative effect on our business, financial condition, or results of operations. 38 ITEM 1B. UNRESOLVED STAFF COMMENTS None. ITEM 2. PROPERTIES As of January 31, 2017, we had a total of 145 properties consisting of 78 full-service branch offices and 67 other offices.

All shares repurchased under the Stock Repurchase Program were retired upon settlement. 41 Five-Year Stock Performance Graph The following chart compares the yearly percentage change in the cumulative stockholder return on our common stock based on the closing price during the five years ended December 31, 2016, with (1) the Total Return Index for U.S. companies traded on The Nasdaq Stock Market (the ‘‘NASDAQ Composite Index’’), and (2) the Total Return Index for KBW NASDAQ Regional Bank Stocks (the ‘‘KBW Regional Banking Index’’). This comparison assumes $100 was invested on December 31, 2011, 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. The Company’s total cumulative gain was 248.1% over the five year period ending December 31, 2016 compared to gains of 116.5% and 140.1% for the NASDAQ Composite Index and KBW Regional Banking Index.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Overview PacWest Bancorp is a bank holding company registered under the BHCA. Our principal business is to serve as the holding company for our Los Angeles-based wholly-owned banking subsidiary, Pacific Western Bank. References to ‘‘Pacific Western’’ or the ‘‘Bank’’ refer to Pacific Western Bank together with its wholly-owned subsidiaries. References to ‘‘we,’’ ‘‘us,’’ or the ‘‘Company’’ refer to PacWest Bancorp together with its subsidiaries on a consolidated basis. When we refer to ‘‘PacWest’’ or to the ‘‘holding company,’’ we are referring to PacWest Bancorp, the parent company, on a stand-alone basis. We are focused on relationship-based business banking to small, middle-market and venture- backed businesses nationwide. The Bank offers a broad range of deposit products and services through 77 full-service branches located throughout the state of California, one branch in Durham, North Carolina, and several loan production offices located in cities across the country. We provide commercial banking services, including real estate, construction, and commercial loans, and comprehensive deposit and treasury management services to small and middle-market businesses. We offer additional products and services through our CapitalSource and Square 1 Bank divisions. Our CapitalSource Division provides cash flow, asset-based, equipment, and real estate loans and treasury management services to established middle market businesses on a national basis. Our Square 1 Bank Division offers a comprehensive suite of financial services focused on entrepreneurial businesses and their venture capital and private equity investors, with offices located in key innovation hubs across the United States. In addition, we provide investment advisory and asset management services to select clients through Square 1 Asset Management, Inc., a wholly-owned subsidiary of the Bank and a SEC-registered investment adviser. At December 31, 2016, we had total assets of $21.9 billion, including $15.5 billion of loans and leases, net of deferred fees, compared to $21.3 billion of total assets, including $14.5 billion of loans and leases, net of deferred fees, at December 31, 2015. Total assets increased $581.3 million during 2016 due to a $977.7 million increase in loans and leases, net of deferred fees, driven by new production, offset partially by a $335.6 million decrease in securities available-for-sale due to paydowns and sales from ongoing portfolio management activities. At December 31, 2016, we had total liabilities of $17.4 billion, including total deposits of $15.9 billion and borrowings of $905.8 million compared to $16.9 billion of total liabilities, including total deposits of $15.7 billion and borrowings of $621.9 million at December 31, 2015. The $499.9 million increase in total liabilities since year-end is due to a $2.0 billion increase in lower-cost core deposits, a $283.9 million increase in borrowings, primarily overnight FHLB advances, and a $232.2 million increase in brokered non-maturity deposits, offset by a $2.0 billion decrease in higher-cost time deposits. At December 31, 2016, core deposits totaled $12.5 billion, or 79% of total deposits, and time deposits totaled $2.2 billion, or 14% of total deposits. At December 31, 2016, we had total stockholders’ equity of $4.5 billion compared to $4.4 billion at December 31, 2015. During 2016, stockholders’ equity increased $81.4 million, due mainly to $352.2 million in net earnings, offset by $243.4 million in dividends paid. Consolidated capital ratios remained strong with Tier 1 capital and total capital ratios of 12.31% and 15.56% at December 31, 2016. On March 31, 2016, we sold our PWEF leasing unit in Midvale, Utah, including approximately $139 million of outstanding lease balances. 45 Recent Events Sale and Closure of Branches In December 2016, the Bank completed the sale of two branches to First Foundation Bank. The branches were located in Laguna Hills and Seal Beach, California. The deposits of the branches totaled approximately $180 million, principally comprised of time deposits. No loans were sold in connection with the sale. In addition, the Bank will close its three branches located in the San Francisco Bay area in the first quarter of 2017. At December 31, 2016, the deposits of these branches totaled approximately $100 million. No significant one-time charges are expected to be incurred related to the closure of these branches. Stock Repurchase Program On October 17, 2016, PacWest’s Board of Directors authorized a stock repurchase program (the ‘‘Stock Repurchase Program’’), pursuant to which the Company may, from time to time, purchase shares of its common stock for an aggregate purchase price not to exceed $400 million. The common stock repurchases may be effected through open market purchases or in privately negotiated transactions and may utilize derivatives or similar instrument to effect share repurchase transactions (including without limitation, accelerated share repurchase contracts, equity forward transactions, equity option transactions, equity swap transactions, cap transactions, collar transactions, floor transactions or other similar transactions or any combination of the foregoing transactions). The Stock Repurchase Program expires on December 31, 2017. The amount and exact timing of any repurchases will depend upon market conditions and other factors. The Stock Repurchase Program may be suspended or discontinued at any time. In the fourth quarter of 2016, the Company repurchased 652,835 shares of common stock for a total amount of $27.9 million under the Stock Repurchase Program and the repurchased shares were retired. Square 1 Financial, Inc. Acquisition PacWest acquired Square 1 on October 6, 2015. As part of the acquisition, Square 1 Bank, a wholly-owned subsidiary of Square 1, merged with and into Pacific Western. At closing, we formed the Square 1 Bank Division of Pacific Western. This division offers a comprehensive suite of financial services focused on entrepreneurial businesses and their venture capital and private equity investors nationwide. We completed this acquisition to increase our core deposits, expand our lending products across the nation, and increase our presence in the technology and life-sciences credit markets. We recorded the assets and liabilities, both tangible and intangible, at their estimated fair values as of the acquisition date and increased total assets by approximately $4.6 billion. The application of the acquisition method of accounting resulted in goodwill of $446 million. For further information, see Note 4. Acquisitions of the Notes to Consolidated Financial Statements contained in ‘‘Item 8. Financial Statements and Supplementary Data.’’ CapitalSource Inc. Merger PacWest acquired CapitalSource Inc. on April 7, 2014. As part of the merger, CapitalSource Bank, a wholly-owned subsidiary of CapitalSource Inc., merged with and into Pacific Western. At closing, we formed the CapitalSource Division of the Bank. This division provides cash flow, asset-based, equipment and real estate loans and treasury management services to established middle market businesses on a national basis. We completed this acquisition in order to increase our loan and lease generation capabilities and to diversify our loan portfolio. We recorded the assets and liabilities, both tangible and intangible, at their estimated fair values as of the merger date and increased total assets by approximately $10.7 billion. The application of the acquisition method of accounting resulted in 46 goodwill of $1.5 billion. For further information, see Note 4. Acquisitions of the Notes to Consolidated Financial Statements contained in ‘‘Item 8. Financial Statements and Supplementary Data.’’ Key Performance Indicators Among other factors, our operating results depend generally on the following key performance indicators: The Level of 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 (annualized) expressed as a percentage of average interest-earning assets. Tax equivalent net interest income is net interest income increased by an adjustment for tax-exempt income on certain municipal securities based on a 35% federal statutory tax rate. Tax equivalent net interest margin is calculated as tax equivalent net interest income divided by average interest-earning assets. Our primary interest-earning assets are loans and investment securities, and our primary interest- bearing liabilities are deposits. Contributing to our high net interest margin is our high yield on loans and leases and competitive cost of deposits. While our deposit balances will fluctuate depending on deposit holders’ perceptions of alternative yields available in the market, we seek to minimize the impact of these variances by attracting a high percentage of noninterest-bearing deposits. We assumed $5.3 billion of time deposits in the CapitalSource Inc. merger. We have substantially completed our goal to replace these higher-costing time deposits with core deposits. The acquisition of Square 1 accelerated this shift in deposit mix as nearly all of the $3.8 billion of acquired deposits were core deposits. The Square 1 acquisition increased our on-balance sheet liquidity and has enabled us to maintain adequate liquidity as we managed down the level of higher-cost time deposits. Loan and Lease Growth We actively seek new lending opportunities under an array of commercial real estate loans and C&I lending products. Our targeted collateral for our real estate loan offerings includes multifamily properties, healthcare properties, office properties, hospitality properties, industrial properties, and retail properties. Our C&I loan products include equipment-secured loans and leases, asset-secured loans, loans to finance companies, cash flow loans (which are loans secured by borrower future cash flows and borrower enterprise value) and venture capital-backed loans to entrepreneurial companies to support the various stages of their operations. Our loan origination process emphasizes credit quality. We foster lending relationships with borrowers that have proven loan repayment performance. Our commitment sizes vary by loan product and can range up to $100 million for certain asset-based lending arrangements and select real estate loans. We price loans to preserve our interest spread and maintain our net interest margin. Achieving net loan growth is subject to many factors, including maintaining strict credit standards, competition from other lenders, and borrowers that opt to prepay loans. 47 The Magnitude of Credit Losses We emphasize credit quality in originating and monitoring our loans and leases, and we measure our success by the levels of our classified and nonperforming assets and net charge-offs. We maintain an allowance for credit losses on loans and leases, which is the sum of our allowance for loan and lease losses and our reserve for unfunded loan commitments. Provisions for credit losses are charged to operations as and when needed for both on and off-balance sheet credit exposure. Loans and leases which are deemed uncollectable are charged off and deducted from the allowance for loan and lease losses. Recoveries on loans and leases previously charged off are added to the allowance for loan and lease losses. The provision for credit losses on the loan and lease portfolio is based on our allowance methodology which considers various credit performance measures such as historical and current net charge-offs, the levels and trends of nonaccrual and classified loans and leases, the migration of loans and leases into various risk classifications, and the overall level of outstanding loans and leases. For originated and acquired non-impaired loans, a provision for credit losses may be recorded to reflect credit deterioration after the origination date or after the acquisition date, respectively. For PCI loans, a provision for credit losses may be recorded to reflect decreases in expected cash flows on such loans compared to those previously estimated. We regularly review our loans and leases to determine whether there has been any deterioration in credit quality stemming from borrower operations or changes in collateral value or other factors which may affect collectability of our loans and leases. Changes in economic conditions, such as the rate of economic growth, the rate of inflation, the unemployment rate, increases in the general level of interest rates, declines in real estate values, changes in commodity prices (such as crude oil), and adverse conditions in borrowers’ businesses, could negatively impact our borrowers and cause us to adversely classify loans and leases. An increase in classified loans and leases generally results in increased provisions for credit losses and an increased allowance for credit losses. Any deterioration in the commercial real estate market may lead to increased provisions for credit losses because of our concentration in commercial real estate loans. The Level of Noninterest Expense Our noninterest expense includes fixed and controllable overhead, the major components of which are compensation, occupancy, data processing, and other professional services. It also includes costs that tend to vary based on the volume of activity, such as loan and lease production and the number and complexity of foreclosed assets. We measure success in controlling both fixed and variable costs through monitoring of the efficiency ratio. We calculate the efficiency ratio by dividing noninterest expense (less intangible asset amortization, net foreclosed assets expense (income), and acquisition, integration and reorganization costs) by net revenues (the sum of tax equivalent net interest income plus noninterest income, less gain (loss) on sale of securities and gain (loss) on sales of assets other than loans and leases).

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 U.S. GAAP. 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.’’ We have identified several policies as being critical because they require management to make particularly difficult, subjective and/or complex judgments about matters that are inherently uncertain and because of the likelihood that materially different amounts would be reported under different conditions or using different assumptions. These policies relate to the allowance for credit losses, the carrying values of intangible assets, the realization of deferred income tax assets, and the accounting for business combinations. Allowance for Credit Losses on Non-PCI Loans and Leases The allowance for credit losses on Non-PCI loans and leases is the combination of the allowance for loan and lease losses and the reserve for unfunded loan commitments. The allowance for loan and lease losses is reported as a reduction of outstanding loan and lease balances and the reserve for unfunded loan commitments is included within ‘‘Accrued interest payable and other liabilities’’ on the consolidated balance sheets. The following discussion is for Non-PCI loans and leases and the related allowance for credit losses. Refer to ‘‘—Allowance for Loan Losses on PCI Loans’’ for the policy on PCI loans. For loans and leases acquired and measured at fair value and deemed non-impaired on the 49 acquisition date, our allowance methodology measures deterioration in credit quality or other inherent risks related to these acquired assets that may occur after the acquisition date. The allowance for credit losses is maintained at a level deemed appropriate by management to adequately provide for known and inherent risks in the loan and lease portfolio and other extensions of credit at the balance sheet date. The allowance is based upon our review of the credit quality of the loan and lease portfolio, which includes loan and lease payment trends, borrowers’ compliance with loan agreements, borrowers’ current and budgeted financial performance, collateral valuation trends, and current economic factors and external conditions that may affect our borrowers’ ability to make payments to us in accordance with contractual terms. Loans and leases that are deemed to be uncollectable are charged off and deducted from the allowance. The provision for loan and lease losses and recoveries on loans and leases previously charged off are added to the allowance. The allowance for loan and lease losses contains a general reserve component for loans and leases with no credit impairment and a specific reserve component for loans and leases determined to be impaired. A loan or lease is considered impaired when it is probable that we will be unable to collect all amounts due according to the original contractual terms of the agreement. We assess our loans and leases for impairment on an ongoing basis using certain criteria such as payment performance, borrower reported financial results and budgets, and other external factors when appropriate. We measure impairment of a loan or lease based upon the fair value of the underlying collateral if the loan or lease is collateral-dependent or the present value of cash flows, discounted at the effective interest rate, if the loan or lease is not collateral-dependent. To the extent a loan or lease balance exceeds the estimated collectable value, a specific reserve or charge-off is recorded depending upon either the certainty of the estimate of loss or the fair value of the loan’s collateral if the loan is collateral- dependent. Smaller balance loans (under $250,000), with a few exceptions for certain loan types, are generally not individually assessed for impairment but are evaluated collectively. The methodology we use to estimate the general reserve component of our allowance for credit losses considers both quantitative and qualitative criteria. The quantitative criteria uses our actual historical loan and lease charge-off experience on pools of similar loans and leases to establish loss factors that are applied to our current loan and lease balances to estimate inherent credit losses. When estimating the general reserve component for the various pools of similar loan types, the loss factors applied to the loan pools consider the current credit risk ratings, giving greater weight to loans with more adverse credit risk ratings. We recognize that the determination of the allowance for credit losses is sensitive to the assigned credit risk ratings and inherent loss rates at any given point in time. To ensure the accuracy of our credit risk ratings, an independent credit review function assesses the appropriateness of the credit risk ratings assigned to loans on a regular basis. The qualitative criteria we consider when establishing the loss factors include the following: (cid:129) current economic trends and forecasts; (cid:129) current commercial real estate values, performance trends, and overall outlook in the markets where we lend; (cid:129) legal and regulatory matters that could impact our borrowers’ ability to repay our loans and leases; (cid:129) loan and lease portfolio composition and any loan concentrations; (cid:129) current lending policies and the effects of any new policies or policy amendments; (cid:129) loan and lease production volume and mix; (cid:129) loan and lease portfolio credit performance trends; 50 (cid:129) results of our independent credit review; and (cid:129) changes in management related to credit administration functions. We estimate the reserve for unfunded commitments using the same loss factors as used for the allowance for loan and lease losses and is computed based only on the expected usage of the unfunded commitments. The credit risk ratings assigned to every loan and lease are either ‘‘pass,’’ ‘‘special mention,’’ ‘‘substandard’’ or ‘‘doubtful’’ and defined as follows: (cid:129) Pass: Loans and leases classified as ‘‘pass’’ are not adversely classified and collection and repayment in full are expected. (cid:129) Special Mention: Loans and leases classified as ‘‘special mention’’ have a potential weakness that requires management’s attention. If not addressed, these potential weaknesses may result in further deterioration in the borrower’s ability to repay the loan or lease. (cid:129) Substandard: Loans and leases classified as ‘‘substandard’’ have a well-defined weakness or weaknesses that jeopardize the collection of the debt. They are characterized by the possibility that we will sustain some loss if the weaknesses are not corrected. (cid:129) Doubtful: Loans and leases classified as ‘‘doubtful’’ have all the weaknesses of those classified as ‘‘substandard,’’ with the additional trait that the weaknesses make collection or repayment in full highly questionable and improbable. In addition, we may refer to the loans and leases with assigned credit risk ratings of ‘‘substandard’’ and ‘‘doubtful’’ together as ‘‘classified’’ loans and leases. For further information on classified loans and leases, see Note 7. Loans and Leases of the Notes to Consolidated Financial Statements contained in ‘‘Item 8. Financial Statements and Supplementary Data.’’ Management believes the allowance for credit losses is appropriate for the known and inherent risks in our Non-PCI loan and lease portfolio and the credit risk ratings and inherent loss rates currently assigned are appropriate. It is possible that others, given the same information, may at any point in time reach different conclusions that could result in a significant impact to the Company’s financial statements. In addition, current credit risk ratings are subject to change as we continue to monitor our loans and leases. To the extent we experience, for example, increased levels of borrower loan defaults, borrowers’ noncompliance with our loan agreements, adverse changes in collateral values, or negative changes in economic and business conditions that adversely affect our borrowers, our classified loans and leases may increase. Higher levels of classified loans and leases generally result in increased provisions for credit losses and an increased allowance for credit losses. Although we have established an allowance for credit losses that we consider appropriate, there can be no assurance that the established allowance will be sufficient to absorb future losses. Allowance for Loan Losses on PCI Loans We measure the allowance for loan losses for PCI loans at the end of each financial reporting period based on expected cash flows of our PCI loans. Decreases or (increases) in the amount and changes in the timing of expected cash flows on the PCI loans as of the financial reporting date compared to those previously estimated are usually recognized by recording a provision or a (negative provision) for credit losses on such loans. For example, a decrease in the expected cash flows of PCI loans would result in an additional reserve requirement and a provision for PCI loan credit losses would be recorded. 51 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 which involve contingencies must also be recognized at their estimated fair value, provided such fair value can be determined during the measurement period. Acquisition-related costs, including severance, conversion and other restructuring charges, such as abandoned space accruals, are expensed. Results of operations of an acquired business are included in the statement of earnings from the date of acquisition. Goodwill and Other Intangible Assets Goodwill and other intangible assets arise from the acquisition method of accounting for business combinations. Goodwill and other intangible assets generated from business combinations and deemed to have indefinite lives are not subject to amortization and are instead tested for impairment at least annually. 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 the evaluation of these intangibles is the attrition rate of the acquired customer relationships. If such attrition rate were to accelerate from that which we expected, the intangible asset may have to be reduced by a charge to earnings. The attrition rate 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. We determine whether a deferred tax asset is realizable based on 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. 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 and, accordingly, we could be required to record a valuation allowance on our deferred tax assets by charging earnings. 52 Non-GAAP Measurements We use certain non-GAAP financial measures to provide meaningful supplemental information regarding the Company’s operational performance and to enhance investors’ overall understanding of such financial performance. The methodology for determining these non-GAAP measures may differ among companies. We use the following non-GAAP measures in this Form 10-K: (cid:129) Core NIM and core loan and lease yield: The tax equivalent NIM and loan and lease yield are impacted by volatility in accelerated accretion of acquisition discounts due to the prepayment of acquired loans and leases. We disclose the core NIM and core loan and lease yield to provide an indication of what these measures would be without the effects of accelerated accretion as we believe this indicates a ‘‘normalized’’ measure and a more accurate indicator of future performance. See ‘‘—Results of Operations—Net Interest Income’’ for a reconciliation of these non-GAAP measurements to the GAAP measurements for the periods presented. (cid:129) Adjusted allowance for credit losses to loans and leases: As the allowance for credit losses takes into consideration credit deterioration on acquired loans and leases only after the purchase date and an estimate of credit losses is included in their initial fair values, we disclose two adjusted allowance for credit losses to loans and leases ratios in addition to the allowance for credit losses to loans and leases. The first adjusted allowance for credit losses to loans and leases excludes the allowance related to acquired loans and leases from the numerator and the acquired loans and leases from the denominator. The second ratio adds back the remaining unamortized purchase discount to both the numerator and the denominator. We disclose these ratios to more clearly illustrate the amounts established on our balance sheet for credit losses related to acquired loans in addition to the allowance for credit losses. See ‘‘—Balance Sheet Analysis—Allowance for Credit Losses on Non-PCI Loans and Leases’’ for a reconciliation of these non-GAAP measurements to the GAAP measurement as of the dates presented. (cid:129) Return on average tangible equity, tangible common equity ratio, and tangible book value per share: Given that the use of these measures is prevalent among banking regulators, investors and analysts, we disclose them in addition to the related GAAP measures of return on average equity, equity to assets ratio, and book value per share, respectively. The reconciliations of these non-GAAP measurements to the GAAP measurements are presented in the following tables for and as of the periods presented. 53 Return on Average Tangible Equity: Year Ended December 31, 2016 2015 2014 Net earnings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ 352,166 (Dollars in thousands) $ 299,619 $ 168,905 Average stockholders’ equity . . . . . . . . . . . . . . . . . . . . . . . . . .

We completed the following acquisitions during the three years ended December 31, 2016: (1) CapitalSource Inc. on April 7, 2014 and (2) Square 1 on October 6, 2015. These acquisitions have been accounted for using the acquisition method of accounting and, accordingly, their operating results have been included in the consolidated financial statements from their respective acquisition dates. Earnings Performance 2016 Compared to 2015 Net earnings for the year ended December 31, 2016 were $352.2 million, or $2.90 per diluted share, compared to net earnings for the year ended December 31, 2015 of $299.6 million, or $2.79 per diluted share. The $52.5 million increase in net earnings was due to higher net interest income of $137.9 million and higher noninterest income of $28.2 million, offset by higher noninterest expense of $68.1 million and a higher provision for credit losses of $20.2 million. These increases were due primarily to including the operations of Square 1 for the entire 2016 period and only subsequent to the October 6, 2015 acquisition date for the 2015 period. The increase in net interest income was attributable to higher average interest-earning asset balances and lower interest expense, offset by lower discount accretion on acquired loans and lower yields on average loans and leases and investment securities. The increase in noninterest income was due mainly to higher other commissions and fees, higher leased equipment income, higher gain on sale of securities, lower FDIC loss sharing expense, and higher service charges on deposit accounts, offset by lower dividends and realized gains on equity investments. 2015 Compared to 2014 Net earnings for the year ended December 31, 2015 were $299.6 million, or $2.79 per diluted share, compared to net earnings for the year ended December 31, 2014 of $168.9 million, or $1.92 per diluted share. The $130.7 million increase in net earnings was due to higher net interest income of $161.0 million, higher noninterest income of $42.1 million, and lower acquisition, integration, and reorganization costs of $79.8 million, offset by higher noninterest expense of $56.2 million (excluding acquisition, integration, and reorganization costs) and a higher provision for credit losses of $34.0 million. These changes, excluding acquisition, integration, and reorganization costs, were due primarily to including the operations of CapitalSource Inc. for the entire 2015 period and only subsequent to the April 7, 2014 merger date for the 2014 period, and to the inclusion of the operations of Square 1 subsequent to the October 6, 2015 acquisition date. The increase in net interest income was attributable mainly to higher average interest-earning asset balances. The increase in noninterest income was due mainly to higher dividends and realized gains on equity investments, lower FDIC loss sharing expense, higher other commissions and fees, and higher leased equipment income. Net Interest Income Net interest income, which is our principal source of revenue, represents the difference between interest earned on interest-earning assets and interest paid on interest-bearing liabilities. Net interest margin is net interest income expressed as a percentage of average interest-earning assets. Net interest income is affected by changes in both interest rates and the volume of average interest-earning assets and interest-bearing liabilities. 55 The following table summarizes the distribution of average assets, liabilities and stockholders’ equity, as well as interest income and yields earned on average interest-earning assets and interest expense and rates paid on average interest-bearing liabilities, presented on a tax equivalent basis for the years indicated: Year Ended December 31, 2016 2015 2014 Average Balance Interest Income/ Expense Yields and Rates Average Balance Yields Interest Income/ and Expense Rates Average Balance Yields Interest Income/ and Expense Rates (Dollars in thousands) $ 134,101 14,487,467 $ 14,621,568 3,344,920 51,905 872,389 924,294 110,077 38.71% $ 212,630 6.02% 12,368,432 $ 31,909 787,185 15.01% $ 347,124 6.36% 9,079,217 $ 57,105 599,992 16.45% 6.61% 6.32% 12,581,062 3.29% 2,150,408 819,094 75,836 6.51% 9,426,341 3.53% 1,574,294 657,097 53,737 6.97% 3.41% 206,404 1,061 0.51% 182,804 476 0.26% 129,920 333 0.26% 18,172,892 1,035,432 5.70% 14,914,274 895,406 6.00% 11,130,555 711,167 6.39% ASSETS: PCI loans . . . . . . . . . . .

Includes tax-equivalent adjustments of $19.5 million, $11.5 million, and $6.4 million for 2016, 2015 and 2014, respectively, related to tax-exempt income on municipal securities. The federal statutory rate utilized was 35% for all years. Total deposits is the sum of interest-bearing deposits and noninterest-bearing demand deposits. The cost of total deposits is calculated as annualized interest expense on deposits divided by average total deposits. Funding sources is the sum of interest-bearing liabilities and noninterest-bearing demand deposits. The cost of funding sources is calculated as annualized total interest expense divided by average funding sources. 56 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. The following table presents, for the years indicated, changes in interest income and expense and the amount of change attributable to changes in volume and rate: 2016 Compared to 2015 2015 Compared to 2014 Total Increase (Decrease) Increase (Decrease) Due to Volume Rate Total Increase (Decrease) Increase (Decrease) Due to Volume Rate (In thousands) Interest Income: Loans and leases . . . . . . . . . . . . .

The loan and lease yield for the year ended December 31, 2016 was 6.32% compared to 6.51% for 2015. The decrease in the loan and lease yield was due mainly to the lower discount accretion on acquired loans and yields on new production being lower than the average portfolio yield. Total discount accretion on acquired loans was $79.5 million for the year ended December 31, 2016 (55 basis points on the loan and lease yield) compared to $89.7 million for 2015 (71 basis points on the loan and lease yield). Discount accretion for the year ended December 31, 2016 includes $25.6 million of accelerated accretion from the payoff of two nonaccrual PCI loans, resulting in the higher PCI loan yield. The tax equivalent NIM for the year ended December 31, 2016 was 5.40% compared to 5.60% for 2015. The decrease in the tax equivalent NIM was due mostly to the decrease in the loan and lease yield as described above and loans and leases comprising a lower percentage of average interest-earning assets. Total discount accretion on acquired loans contributed 43 basis points to the NIM for the year ended December 31, 2016 compared to 60 basis points for 2015. Tax-exempt interest income contributed 11 basis points to the tax equivalent NIM for the year ended December 31, 2016 and eight basis points for 2015. The cost of total deposits decreased to 0.20% for the year ended December 31, 2016 from 0.32% for 2015 due mainly to the $3.8 billion of lower-cost core deposits added in the Square 1 acquisition, a lower level of higher-cost time deposits, and a lower average cost of interest-bearing deposits. 2015 Compared to 2014 Net interest income increased by $161.0 million to $823.3 million for the year ended December 31, 2015 compared to $662.4 million for 2014 due to the significant increase in interest-earning assets acquired in the CapitalSource Inc. merger on April 7, 2014 and, to a lesser extent, the Square 1 acquisition on October 6, 2015. The loan and lease yield for the year ended December 31, 2015 was 6.51% compared to 6.97% for 2014. The decrease in the loan and lease yield was due mainly to yields on new production being lower than the average portfolio yield and the discount accretion on acquired loans and leases having a smaller positive impact on the loan and lease yield in 2015 compared to 2014. Total discount accretion on acquired loans was $89.7 million for the year ended December 31, 2015 (71 basis points on the loan and lease yield) compared to $87.6 million for 2014 (93 basis points on the loan and lease yield). Although the dollar amount of accretion was slightly higher in 2015 compared to 2014, the basis point impact to the loan and lease yield was significantly less due to the higher average loan and lease balance in 2015. The tax equivalent NIM for the year ended December 31, 2015 was 5.60% compared to 6.01% for 2014. The decrease in the tax equivalent NIM was due mostly to the decrease in the loan and lease yield as described above and lower accretion of time deposit acquisition premium. Total discount accretion on acquired loans contributed 60 basis points to the NIM for the year ended December 31, 2015 compared to 79 basis points for 2014. Although the dollar amount of accretion was slightly higher in 2015 compared to 2014, the basis point impact to the NIM was significantly less due to the higher average interest-earning assets balance in 2015. The positive impact on the NIM from accretion of time deposits acquisition premium was two basis points for 2015 compared to 13 basis points for 2014. Tax-exempt interest income contributed eight basis points to the tax equivalent NIM for the year ended December 31, 2015 and six basis points for 2014. The cost of total deposits increased to 0.32% for the year ended December 31, 2015 from 0.28% for 2014 due mainly to the $5.3 billion of higher-cost time deposits acquired in the CapitalSource Inc. merger contributing to the deposit cost for the entire 12-month period in 2015 compared to contributing for only nine months in 2014. 59 Provision for Credit Losses The following table sets forth the details of the provision for credit losses and allowance for credit losses data for the years indicated: Provision For Credit Losses: Addition to allowance for Non-PCI loans and leases . . . . . . . . . . . . . . . . . . . . .

We have a provision for credit losses on our Non-PCI loans and leases and a provision for credit losses on our PCI loans. The provision for credit losses on our Non-PCI loans and leases is based on our allowance methodology and is an expense, or contra-expense, that, in our judgment, is required to maintain an adequate allowance for credit losses. Our allowance methodology uses our actual historical loan and lease charge-off experience on pools of similar loans and leases, considers the current credit risk ratings, giving greater weight to loans with more adverse credit risk ratings, and considers qualitative criteria such as current economic trends and forecasts, current commercial real estate values and performance trends, and the loan portfolio credit performance trends. The provision for credit losses on our PCI loans results from decreases or increases in expected cash flows on such loans compared to those previously estimated. We recorded a provision for credit losses of $65.7 million for the year ended December 31, 2016 and $45.5 million for 2015 in accordance with our allowance methodology. The provision for credit losses increased due to net portfolio growth, an increased level of specific reserves, and increases in general reserves on acquired loans. 60 Certain circumstances may lead to increased provisions for credit losses in the future. Examples of such circumstances are an increased amount of classified and/or impaired loans and leases, net loan and lease and unfunded commitment growth, and changes in economic conditions. Changes in economic conditions include the rate of economic growth, the rate of inflation, the unemployment rate, increases in the general level of interest rates, declines in real estate values, and adverse conditions in borrowers’ businesses.

The increase was due mostly to higher other commissions and fees of $15.5 million, higher leased equipment income of $9.9 million, lower FDIC loss sharing expense of $9.3 million, higher gain on sales of securities of $5.7 million, and higher service charges on deposit accounts of $2.8 million, offset by lower dividends and realized gains on equity investments of $16.6 million. The increase in other commissions and fees was comprised mostly of $5.7 million from foreign exchange fees, $4.8 million from loan prepayment penalty fees, $2.6 million from credit card fees, and $1.9 million from letter of credit fees. The increases in foreign exchange fees and credit card fees were due to the Square 1 acquisition. The decrease in FDIC loss sharing expense was due to the termination of all FDIC loss sharing agreements in the second quarter of 2016. The increase in service charges on deposits was due primarily to increased deposits as a result of the Square 1 acquisition. Regarding the decrease in dividends and realized gains on equity investments, the 2016 period included net gains of $2.3 million on the sale of equity investments and dividends received of $1.9 million, while 61 the 2015 period included net gains of $6.1 million on the sale of equity investments and dividends received of $14.7 million. We had 11 equity investments with an aggregate carrying value of $1.4 million at December 31, 2016 and 15 equity investments with an aggregate carrying value of $2.3 million at December 31, 2015. These equity investments were acquired in the CapitalSource Inc. and Square 1 transactions. Dividends on equity investments are solely at the discretion of the investee, and we have no control over the amount of such distributions in each period. 2015 Compared to 2014 Noninterest income increased by $42.1 million to $84.3 million for the year ended December 31, 2015 compared to $42.2 million for 2014. The increase was due mostly to a $14.7 million increase in dividends and realized gains on equity investments, lower FDIC loss sharing expense of $13.5 million, higher other commissions and fees of $13.0 million and higher leased equipment income of $7.4 million. The 2015 period included a net gain of $6.1 million on the sale of equity investments and dividends received of $14.7 million. The 2014 period included a net gain of $2.6 million on the sale of equity investments and dividends received of $3.7 million. We had equity investments with an aggregate carrying value of $2.3 million at December 31, 2015 and $25.2 million at December 31, 2014. The decrease in FDIC loss sharing expense resulted primarily from an $11.6 million decline in the amortization expense of the FDIC loss sharing asset, as two of the Bank’s loss sharing agreements reached the end of their initial indemnification period during the third quarters of 2015 and 2014. The increase in other commissions and fees was due to higher loan-related unused commitment fees and prepayment fees, and higher foreign exchange fees due to the impact of the income sources gained in the CapitalSource Inc. merger and Square 1 acquisition.

The increase was due primarily to including the operations of Square 1 for the entire 2016 period and only subsequent to its October 6, 2015 acquisition date for the 2015 period, higher leased equipment depreciation of $7.3 million, higher loan-related expense of $3.3 million, and higher foreclosed assets expense of $2.5 million, offset by lower acquisition, integration and reorganization costs of $21.0 million. Leased equipment depreciation increased due to the higher average portfolio balance in 2016. Loan-related expense increased due to a large recovery of workout expenses in 2015 on a single loan of $2.3 million. Foreclosed assets expense increased due mainly to lower operating income and lower gains on sales, offset partially by lower provision for losses. 2015 Compared to 2014 Noninterest expense decreased by $23.6 million to $382.0 million for the year ended December 31, 2015 compared to $405.6 million for 2014. The decrease was due mainly to lower acquisition, integration and reorganization costs of $79.8 million. The acquisition, integration and reorganization costs for 2015 related to the Square 1 acquisition, and the costs for 2014 related to the CapitalSource Inc. merger. Almost all of the of the operating expense categories were higher in 2015 compared to 2014 due mostly to including the operations of CapitalSource Inc. for the entire 2015 period and only subsequent to its April 7, 2014 acquisition date for the 2014 period, and to the inclusion of the operations of Square 1 subsequent to its October 6, 2015 acquisition date. Foreclosed assets expense decreased by $6.1 million due mainly to lower operating expenses and lower provision for losses. Income Taxes The effective tax rates were 36.9%, 37.6% and 40.7% in 2016, 2015 and 2014. The difference in the effective tax rates between the years relates mainly to the level of tax credits and the amount of tax-exempt interest income recorded in each of the years, the non-deductibility of certain acquisition, integration and reorganization costs, and the amount of any change in valuation allowance for the year in question. The Company’s blended statutory tax rate for federal and state is 41%. For further information on income taxes, see Note 14.

See ‘‘Non-GAAP Measurements.’’ Calculation excludes accelerated accretion of acquisition discounts from early payoffs of acquired loans. Fourth Quarter of 2016 Compared to Third Quarter of 2016 Net earnings were $85.6 million, or $0.71 per diluted share, for the fourth quarter of 2016 compared to $93.9 million, or $0.77 per diluted share, for the third quarter of 2016. The quarter-over-quarter decrease of $8.2 million in net earnings was due mostly to the $14.7 million increase in provision for credit losses and the $7.9 million increase in noninterest expense, offset by the $13.7 million increase in net interest income and the $2.0 million increase in noninterest income. The higher fourth quarter 2016 provision for credit losses was due to significant loan and lease portfolio growth, downgrades of acquired loans, and lower recoveries. 64 The NIM and loan and lease yield are impacted by accelerated accretion of acquisition discounts resulting from early payoffs of acquired loans that causes volatility from period to period.

The loan and lease yield for the fourth quarter of 2016 was 6.31% compared to 6.17% for the third quarter of 2016. The increase in the loan and lease yield was due to the higher accretion on acquired loans offset by a lower yield on new production relative to the current portfolio yield. Total accretion on acquired loans was $21.2 million in the fourth quarter of 2016 (56 basis points on the loan and lease yield) compared to $14.2 million in the third quarter of 2016 (39 basis points on the loan and lease yield). Excluding accelerated accretion, the core loan and lease yield was 5.85% in the fourth quarter compared to 5.94% in the third quarter. The higher discount accretion in the fourth quarter of 2016 was due to $13.5 million of accelerated accretion from the payoff of a nonaccrual PCI loan. 65 The tax equivalent NIM for the fourth quarter of 2016 was 5.47% compared to 5.26% for the third quarter of 2016. The increase in the NIM was due to higher accretion on acquired loans. Such accretion contributed 46 basis points to the NIM in the fourth quarter of 2016 and 31 basis points to the NIM in the third quarter of 2016. Excluding accelerated accretion, the core NIM was 5.09% for the fourth quarter compared to 5.08% for the third quarter. Tax-exempt interest income contributed 10 basis points to the tax equivalent NIM for the fourth quarter of 2016 and 11 points to the tax equivalent NIM for the third quarter of 2016. Included in net interest income for the third quarter of 2016 was $3.0 million of interest resulting from the full payoff of a nonperforming loan. This recovery contributed seven basis points to the third quarter 2016 NIM and eight basis points of loan and lease yield for the third quarter of 2016. The cost of total deposits was 0.19% in the fourth quarter of 2016, unchanged from the third quarter of 2016. We recorded a provision for credit losses of $23.2 million in the fourth quarter of 2016 compared to a provision for credit losses of $8.5 million in the third quarter of 2016 as follows: Three Months Ended December 31, 2016 September 30, 2016 Increase (Decrease) (In thousands) Provision for Credit Losses: Non-PCI loans and leases . . . . . . . . . . . . . . . . . . . . . . . . . . .

Noninterest expense increased by $7.9 million to $118.6 million for the fourth quarter of 2016 compared to $110.7 million for the third quarter of 2016. The increase was due mostly to higher compensation expense of $3.4 million, higher foreclosed assets expense of $2.9 million, higher loan expense of $1.2 million, and higher other expense of $1.0 million, offset by lower intangible asset amortization of $1.0 million. Compensation expense increased due mainly to higher severance, bonus, and commissions expense. Foreclosed assets expense increased due primarily to a $2.6 million write-down on an existing property. Loan expense increased primarily due to a $0.9 million recovery of work-out expenses for a single credit in the third quarter. Intangible asset amortization decreased due to declining amortization on the Square 1 customer deposit and customer relationship intangible assets.

Commercial loans and leases are diversified among various loan types and industries. At December 31, 2016, our largest commercial loan type concentration was cash flow loans, totaling $3.1 billion or 20% of our total portfolio compared to $3.1 billion or 21% at December 31, 2015. Cash flow loans are provided to sophisticated buyers and private equity groups, financial investors, strategic companies and sponsors to finance the acquisition or recapitalization of a business. Other significant commercial concentrations were asset-based loans at 17% and 18% of the total portfolio at December 31, 2016 and December 31, 2015 and venture capital loans at 13% and 10% of the total portfolio at December 31, 2016 and December 31, 2015. Asset-based loans are secured by first liens on or interests in readily quantifiable collateral. This collateral includes, but is not limited to, finance receivables, trade accounts receivable, and/or inventory. Venture capital loans support the operations of entrepreneurial companies during the various phases of their life cycle. See ‘‘Item 1. Business—Our Business Strategy—Lending Activities’’ for an overview of commercial loan credit risk and risk mitigation commentary. Real estate mortgage loans and real estate construction and land loans (which are predominantly commercial real estate mortgage loans) together comprised 43% and 44% of our total portfolio at December 31, 2016 and 2015. The mix of our real estate loan portfolio shifted during 2016 as we invested in additional resources focused on multi-family and construction lending. Real estate mortgage loans declined to 37% of total loans and leases at December 31, 2016 from 41% at December 31, 2015, while real estate construction and land loans increased to 6% of total loans and leases at December 31, 2016 from 3% at December 31, 2015. Real estate mortgage loans are diversified among various property types. At December 31, 2016, our two largest property type concentration were income producing residential property, totaling $1.2 billion or 20% of real estate mortgage loans, and healthcare property, totaling $1.0 billion or 17% of real estate mortgage loans. Income producing residential property is primarily multi-family properties but also included are portfolios of for-rent 1-4 family properties. Healthcare property types are primarily skilled nursing facilities and assisted living facilities. At December 31, 2015, income producing residential property totaled $1.0 billion or 18% of real estate mortgage loans, and healthcare property totaled $1.2 billion and comprised 21% of real estate mortgage loans. Other significant real estate mortgage loan concentrations were office properties at 15% and 12% of real estate mortgage loans at December 31, 2016 and 2015, and hospitality properties at 12% and 11% of real estate mortgage loans at December 31, 2016 and 2015. See ‘‘Item 1. Business—Our Business Strategy—Lending Activities’’ for an overview of the real estate loan structures and the related credit risk and risk mitigation commentary. Our real estate portfolio exposes us to risk elements associated with mortgage loans on commercial property. For commercial real estate loans, the respective primary and secondary sources of loan repayments are the net operating incomes of the properties and the proceeds from the sales or refinancings of the properties. As such, our commercial real estate borrowers generally are required to refinance the loans with us or another lender or sell the properties to repay our loans. 70 The following table presents the geographic composition of the majority of our real estate loans as of the dates indicated: Real Estate Loans by State: December 31, 2016 December 31, 2015 Amount % of Total Amount % of Total (Dollars in thousands) California . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Our real estate loans with collateral located in New York increased to $524.8 million, or 8%, at December 31, 2016 from $315.4 million, or 5%, at December 31, 2015 due to increased construction lending in New York City and its boroughs. At December 31, 2016, New York City real estate loans were primarily secured by condominium projects, office properties, and retail properties.

For any of these loans and leases, in the event that we provide a concession through a refinance or modification which we would not ordinarily consider in order to protect as much of our investment as possible, such loans may be considered TDRs even though the loans performed throughout their terms. The circumstances regarding any modifications 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 TDR has occurred. Higher levels of TDRs may lead to increased classified assets and credit loss provisions.

The obligors under these loans and leases either conduct oil and gas extraction or provide industrial support services to such types of businesses. The collateral for these loans and leases primarily includes equipment, such as drilling and mining equipment and transportation vehicles, used directly and indirectly in these activities. At December 31, 2016, one relationship totaling $30.3 million was on nonaccrual status and was classified, down from three relationships totaling $47.1 million at December 31, 2015. Reserves related to our total oil and gas services industry exposure were approximately 2.4% at December 31, 2016. Unfunded commitments related to the oil and gas portfolio totaled $8.1 million at December 31, 2016 as a result of three relationships governed with a borrowing base for accounts receivable and inventory.

These acquired loans and leases were initially recorded at their estimated fair values and such initial fair values included an estimate of credit losses. The allowance calculation for Non-PCI loans and leases takes into consideration those acquired loans and leases whose credit quality has deteriorated since their acquisition dates. At December 31, 2016, our allowance for credit losses included $44.4 million related to these acquired loans and leases. When these acquired loans and leases are excluded from the total of Non-PCI loans and leases and the related allowance is excluded from the allowance for credit losses, the result is an adjusted coverage ratio of our allowance for credit losses to Non-PCI loans and leases of 1.06% at December 31, 2016; at December 31, 2015 this ratio was 1.24%. The second additional credit coverage ratio calculation makes an adjustment for the unamortized purchase discount on acquired loans and leases. Our acquired Non-PCI loans and leases included an unamortized purchase discount of $45.6 million at December 31, 2016, which is assigned specifically to those loans and leases only. Such discount represents the acquisition date fair value adjustment based on market, liquidity, interest rate and credit risk. When the unamortized purchase discount is added back separately to both our Non-PCI loans and leases and allowance for credit losses, the result is an adjusted coverage ratio of our allowance for credit losses to Non-PCI loans and leases of 1.34% at December 31, 2016; at December 31, 2015 this ratio was 1.49%. The unamortized purchase discount is being accreted to interest income over the remaining life of the respective loans and leases primarily using the interest method. Use of the interest method results in steadily declining amounts being taken into income in each reporting period. The remaining discount of $45.6 million at December 31, 2016 is expected to be substantially accreted to income by the end of 2018. 74 The following table presents the changes in our allowance for credit losses on Non-PCI loans and leases for the years indicated: Non-PCI Allowance for Credit Losses: 2016 2015 2014 2013 2012 Year Ended December 31, Allowance for credit losses, beginning of year . .

The increase in the allowance allocated to commercial loans was due to net loan growth in 2016 and a larger balance of specific reserves on commercial loans at December 31, 2016 compared to December 31, 2015.

Nonperforming assets include Non-PCI and PCI nonaccrual loans and leases and foreclosed assets and totaled $186.5 million at December 31, 2016 compared to $156.4 million at December 31, 2015. The $30.1 million increase in nonperforming assets was due mainly to a $39.9 million increase in nonaccrual loans and leases offset partially by a $9.1 million decrease in foreclosed assets. The ratio of nonperforming assets to loans and leases and foreclosed assets increased to 1.20% at December 31, 2016 from 1.08% at December 31, 2015. During 2016, Non-PCI classified loans and leases increased by $17.9 million to $409.6 million at December 31, 2016 as new downgrades exceeded resolutions. Nonaccrual Loans and Leases During 2016, nonaccrual loans and leases increased by $39.9 million to $173.5 million at December 31, 2016 due mainly to new additions of $156.1 million, offset by $86.0 million in principal payments, charge-offs, and other reductions and $30.2 million returned to accrual status. Additions included a $48.9 million healthcare real estate loan secured by a continuing care retirement facility that migrated to nonaccrual status during the third quarter of 2016 due to continued weak operating performance and cash flow difficulties. As of December 31, 2016, the Company’s ten largest Non-PCI loan relationships on nonaccrual status had an aggregate carrying value of $146.2 million and represented 85.7% of total Non-PCI nonaccrual loans and leases. The largest of these relationships is the $48.9 million healthcare real estate loan described in the paragraph above. 77 The following table presents our Non-PCI nonaccrual loans and leases and accruing loans and leases past due between 30 and 89 days by portfolio segment and class as of the dates indicated: Non-PCI Nonaccrual Loans and Leases December 31, 2016 December 31, 2015 % of Loan % of Loan Amount Category Amount Category Non-PCI Accruing and 30 - 89 Days Past Due December 31, December 31, 2016 Amount 2015 Amount (Dollars in thousands) Real estate mortgage: Commercial . . . . . . . . . . . . . . . . . . . . . $ 62,454 6,881 Residential . . . . . . . . . . . . . . . . . . . . . . 1.4% $ 52,363 4,914 0.5% 1.2% $ 7,691 5,524 0.4% Total real estate mortgage . . . . . . . . . 69,335 1.2% 57,277 1.0% 13,215 Real estate construction and land: Commercial . . . . . . . . . . . . . . . . . . . . .

At December 31, 2016, we had $54.8 million in real estate mortgage loans, $6.9 million in real estate construction and land loans, $3.2 million in commercial loans, and $0.1 million in consumer loans that were accruing interest under the terms of troubled debt restructurings. The majority of the number of performing troubled debt restructured loans were on accrual status prior to the loan restructurings and have remained on accrual status after the loan restructurings due to the borrowers making payments before and after the restructurings.

At December 31, 2016, core deposits totaled $12.5 billion, or 79% of total deposits, including $6.7 billion of noninterest-bearing demand deposits, or 42% of total deposits. Our deposit base is also diversified by client type. As of December 31, 2016, no individual depositor represented more than 1.4% of our total deposits, and our top ten depositors represented 8.0% of our total deposits. Competition for deposits among banks and financial institutions in our California market area was robust in 2016. 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 substantial portion of our deposits are tied to lending relationships, an economic downturn may lead to lower loan production and lower balances maintained by existing customers. To mitigate these challenges, we actively review our deposit offerings to provide the optimum mix of service, product, and rate, and continually seek new deposits through various programs. The following table summarizes the maturities of time deposits, together with their weighted average contractual rates, as of the date indicated: Maturity: December 31, 2016 Time Deposits Under $100,000 Time Deposits $100,000 or More Total Time Deposits Contractual Rate Due in three months or less . . . . . . . . . . . . . . . . . .

At December 31, 2016 and December 31, 2015, we had $769 million and $858 million, respectively, of time deposits that exceeded the FDIC deposit insurance limit of $250,000, while the remaining $1.4 billion and $3.3 billion of time deposits met or fell below the FDIC deposit insurance limit. Client Investment Funds In addition to deposit products, we also offer select clients non-depository cash investment options through S1AM, our registered investment adviser subsidiary, and third-party money market sweep products. S1AM provides customized investment advisory and asset management solutions. At December 31, 2016, total off-balance sheet client investment funds were $1.3 billion, of which $1.1 billion was managed by S1AM. 80 Borrowings The Bank has various available lines of credit. These include the ability to borrow funds from time to time on a long-term, short-term, or overnight basis from the FHLB, the FRBSF, or other financial institutions. The maximum amount that the Bank could borrow under its secured credit lines with the FHLB at December 31, 2016 was $2.0 billion, of which $1.3 billion was available on that date. The maximum amount that the Bank could borrow under its secured credit line with the FRBSF at December 31, 2016 was $2.2 billion, all of which was available on that date. The FHLB secured credit lines are secured by a blanket lien on certain qualifying loans which are not pledged to the FRBSF. In addition to its secured lines of credit, the Bank also maintains unsecured lines of credit, subject to availability, of $130.0 million with the FHLB and $80.0 million with correspondent banks, both for the purchase of overnight funds. In March 2016, the Bank became a member of the American Financial Exchange, through which it may either borrow or lend funds on an overnight or short-term basis with a group of pre-approved commercial banks. The availability of funds changes daily. At December 31, 2016, our borrowings included $735.0 million of secured FHLB advances, $130.0 million of unsecured FHLB advances, $40.0 million of American Financial Exchange borrowings, $0.8 million in non-recourse debt related to the payment stream of certain leases sold to third parties, and $440.7 million in subordinated debentures. At December 31, 2015, our borrowings included $618.0 million of secured FHLB advances, $3.9 million in non-recourse debt related to the payment stream of certain leases sold to third parties, and $436.0 million in subordinated debentures. Regulatory Matters Capital Bank regulatory agencies measure capital adequacy through standardized risk-based capital guidelines that compare different levels of capital (as defined by such guidelines) to risk-weighted assets and off-balance sheet obligations. At December 31, 2016, banks considered to be ‘‘well capitalized’’ must maintain a minimum Tier 1 leverage ratio of 5.00%, a minimum common equity Tier 1 risk-based capital ratio of 6.50%, a minimum Tier 1 risk-based capital ratio of 8.00%, and a minimum total risk-based capital ratio of 10.00%. Regulatory capital requirements limit the amount of deferred tax assets that may be included when determining the amount of regulatory capital. Deferred tax asset amounts in excess of the calculated limit are disallowed from regulatory capital. At December 31, 2016, such disallowed amounts were $2.1 million for the Company and $0.2 million for the Bank. No assurance can be given that the regulatory capital deferred tax asset limitation will not increase in the future or that the Company or Bank will not have increased deferred tax assets that are disallowed. Basel III, the comprehensive regulatory capital rules for U.S. banking organizations and described in greater detail in ‘‘Item 1. Business—Supervision and Regulation—Capital Requirements,’’ became effective for the Company and the Bank on January 1, 2015, subject to phase-in periods for certain components and other provisions. The most significant provisions of Basel III applicable to the Company and the Bank are the phase-out of trust preferred securities from Tier 1 capital, the higher risk-weighting of high volatility and past due real estate loans, and the capital treatment of deferred tax assets and liabilities above certain thresholds. 81 The following tables present a comparison of our actual capital ratios to the minimum required ratios and well capitalized ratios as of the dates indicated: Minimum Required For Capital Adequacy Purposes Actual Minimum Required Plus Capital Conservation Buffer Phase-In for 2016 Minimum Required For Well Capitalized Requirement Minimum Required Plus Capital Conservation Buffer Fully Phased-In December 31, 2016 PacWest Bancorp Consolidated Tier 1 capital (to average assets) . . . . .

The capital conservation buffer is exclusively comprised of common equity tier 1 capital, and it applies to each of the three risk-based capital ratios but not to the leverage ratio. At December 31, 2016, the Company and Bank were in compliance with the capital conservation buffer requirement. The capital conservation buffer will increase by 0.625% each year through 2019, at which point, the common equity tier 1, tier 1 and total capital ratio minimums inclusive of the capital conservation buffer will be 7.0%, 8.5%, and 10.5%. Subordinated Debentures We issued or assumed through mergers subordinated debentures to trusts that were established by us or entities we previously acquired, which, in turn, issued trust preferred securities. The carrying value of subordinated debentures totaled $440.7 million at December 31, 2016. At December 31, 2016, none of the trust preferred securities was included in the Company’s Tier I capital and $428.2 million was included in Tier II capital. For a more detailed discussion of our subordinated debentures, see ‘‘Item 1: Business—Supervision and Regulation—Capital Requirements.’’ 82 Dividends on Common Stock and Interest on Subordinated Debentures As a bank holding company, PacWest is required to notify the FRB prior to declaring and paying a dividend to stockholders during any period in which quarterly and/or cumulative twelve-month net earnings are insufficient to fund the dividend amount, among other requirements. Interest payments made by us on subordinated debentures are considered dividend payments under FRB regulations. Liquidity Liquidity Management The goals of our liquidity management are to ensure the ability of the Company to meet its financial commitments when contractually due and to respond to other demands for funds such as the ability to meet the cash flow requirements of customers who may be either depositors wanting to withdraw funds or borrowers who have unfunded commitments. We have an Executive Management Asset Liability Management Committee (‘‘Executive ALM Committee’’), which is comprised of members of senior management and is responsible for managing 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. We manage our 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. We also maintain available borrowing capacity under secured borrowing lines with the FHLB and the FRBSF, which we refer to as our secondary liquidity. In addition to its secured lines of credit, the Bank also maintains unsecured lines of credit, subject to availability, of $130.0 million with the FHLB and $80.0 million with correspondent banks, both for the purchase of overnight funds. As of December 31, 2016, there was a $130.0 million balance outstanding related to the FHLB unsecured line of credit. In March 2016, the Bank became a member of the American Financial Exchange, through which it may either borrow or lend funds on an overnight or short-term basis with a group of pre-approved commercial banks. The availability of funds changes daily. As of December 31, 2016, there was a $40.0 million balance outstanding.

The Company’s secondary liquidity decreased by $428.3 million during 2016 due to a $443.7 million decrease in the borrowing capacity on the secured credit line with the FHLB and a $117.0 million increase in related advances outstanding, offset partially by a $132.4 million increase in the borrowing capacity on the secured credit line with the FRBSF attributable to additional loans pledged as collateral. As a member of the FHLB, the Bank had secured financing capacity with the FHLB as of December 31, 2016 of $2.0 billion, collateralized by a blanket lien on $2.9 billion of certain qualifying loans not pledged to the FRBSF. The Bank also had secured financing capacity with the FRBSF of $2.2 billion as of December 31, 2016 collateralized by liens on $3.0 billion of qualifying loans. In addition to our primary liquidity, we generate liquidity from cash flow from our loan and securities portfolios and from our large base of core deposits, defined as noninterest-bearing demand, interest checking, savings and non-brokered money market accounts. At December 31, 2016, core deposits totaled $12.5 billion and represented 79% of the Bank’s total deposits. These core deposits are normally less volatile, often with customer relationships tied to other products offered by the Bank promoting long-standing relationships and stable funding sources. See ‘‘—Balance Sheet Analysis— Deposits’’ for additional information and detail of our core deposits. Our deposit balances may decrease if interest rates increase significantly or if corporate customers withdraw funds from the Bank. In order to address the Bank’s liquidity risk as deposit balances may fluctuate, the Bank maintains adequate levels of available off-balance sheet liquidity. Our liquidity policy includes guidelines for On-Balance Sheet Liquidity (a measurement of primary liquidity to total deposits plus borrowings), Coverage and Crisis Coverage Ratios (measurements of liquid assets to expected short-term liquidity required for the loan and deposit portfolios under normal and stressed conditions), Loan to Funding Ratio (measurement of gross loans net of fees divided by deposits plus FHLB borrowings), Wholesale Funding Ratio (measurement of wholesale funding divided by interest-earning assets), and other guidelines developed for measuring and maintaining liquidity. As of December 31, 2016, we were in compliance with all of our established liquidity guidelines. We use brokered deposits, the availability of which is uncertain and subject to competitive market forces and regulation, for liquidity management purposes. At December 31, 2016, brokered deposits totaled $1.6 billion, consisting of $405.5 million of brokered time deposits, $1.2 billion of non-maturity brokered sweep accounts, and $12.2 million of other brokered deposits. At December 31, 2015, brokered deposits totaled $1.2 billion, consisting of $272.5 million of brokered time deposits, $942.3 million of non-maturity brokered sweep accounts, and $15.4 million of other brokered deposits. We have increased the amount of our brokered deposits in recent quarters because of the large amount of deposits that can be obtained in a short period of time to manage liquidity and funding needs. 84 Holding Company Liquidity PacWest acts a source of financial strength for the Bank which can also include being a source of liquidity. The primary sources of liquidity for the holding company include dividends from the Bank, intercompany tax payments from the Bank, and PacWest’s ability to raise capital, issue subordinated debt and secure outside borrowings. Our ability to obtain funds for the payment of dividends to our stockholders, the repurchase of shares of common stock and other cash requirements is largely dependent upon the Bank’s earnings. The Bank is subject to restrictions under certain federal and state laws and regulations that limit its ability to transfer funds to the holding company through intercompany loans, advances or cash dividends. Dividends paid by California state-chartered banks are regulated by the FDIC and the DBO under their general supervisory authority as it relates to a bank’s capital requirements. A state bank may declare a dividend without the approval of the DBO and the FDIC as long as the total dividends declared in a calendar year do not exceed either the retained earnings or the total of net profits for three previous fiscal years less any dividends paid during such period. During the year ended December 31, 2016, PacWest received $259 million in dividends from the Bank. Since the Bank had an accumulated deficit of $520 million at December 31, 2016, for the foreseeable future, any dividends from the Bank to the holding company will continue to require DBO and FDIC approval. At December 31, 2016, PacWest had $495.0 million in cash, of which substantially all is on deposit at the Bank. We believe this amount of cash, along with anticipated dividends from the Bank, will be sufficient to fund the holding company’s cash flow needs over the next 12 months, including any stock repurchases pursuant to the Company’s Stock Repurchase Program. See ‘‘—Recent Events—Stock Repurchase Program’’ for additional information.

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, commitments to contribute capital to investments in low income housing project partnerships and private equity funds, commitments to purchase loans, and commitments under deferred compensation arrangements. We believe that we will be able to meet our contractual obligations as they come due through the maintenance of adequate liquidity levels. We expect to maintain adequate liquidity levels through profitability, loan and lease payoffs, securities repayments and maturities, and continued deposit gathering activities. We also have in place various borrowing mechanisms for both short-term and long-term liquidity needs. Off-Balance Sheet Arrangements Our obligations also include off-balance sheet arrangements consisting of loan and lease-related commitments, of which only a portion is expected to be funded. At December 31, 2016, our loan and lease-related commitments, including standby letters of credit, totaled $4.4 billion. These commitments, a portion of which result in funded loans and leases, increase our profitability through net interest income when drawn. 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—Liquidity Management,’’ 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 expected impact, if any, on our consolidated financial statements. 86 ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Market Risk—Foreign Currency Exchange We enter into foreign exchange contracts with our clients and counterparty banks primarily for the purpose of offsetting or hedging clients’ transaction and economic exposures arising out of commercial transactions. We have experienced and will continue to experience fluctuations in our net earnings as a result of transaction gains or losses related to revaluing certain asset and liability balances that are denominated in currencies other than the U.S. Dollar. We recognized foreign currency gains of $0.5 million and $0.2 million for the years ended December 31, 2016 and 2015. In June 2015, we hedged our Euro-denominated subordinated debentures with a cross currency swap to reduce the related foreign currency translation volatility. Asset/Liability Management and Interest Rate Sensitivity Interest Rate Risk We measure our IRR position on at least a quarterly basis using two methods: (i) NII simulation analysis; and (ii) MVE modeling. The Executive ALM Committee and the Board Asset Liability Management Committee review the results of these analyses quarterly. If hypothetical changes to interest rates cause changes to our simulated net present value of equity and/or net interest income outside our pre-established limits, we may adjust our asset and liability mix in an effort to bring our interest rate risk exposure within our established limits. We evaluated the results of our NII simulation model and MVE model prepared as of December 31, 2016, the results of which are presented below. Our NII simulation and MVE models indicate that our balance sheet is asset sensitive. An asset sensitive profile indicates that a sudden sustained increase in rates would result in an increase in our estimated NII and MVE, while a liability sensitive profile would suggest that these amounts would decrease. Net Interest Income Simulation We used a NII 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, 2016. 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 decreasing interest rate scenarios using the forward yield curve at December 31, 2016. In order to arrive at the base case, we extend our balance sheet at December 31, 2016 one year and reprice any assets and liabilities that would contractually reprice or mature during that period using the products’ pricing spreads as of December 31, 2016. Based on such repricing, we calculate an estimated NII and NIM for each rate scenario. The NII simulation model is dependent upon numerous assumptions. For example, the substantial majority of our loans are variable-rate, which are assumed to reprice in accordance with their contractual terms. Some loans and investment securities include the opportunity of prepayment (imbedded options) and the simulation model uses prepayment assumptions to estimate these prepayments and reinvest these proceeds at current simulated yields. Our deposit products reprice at our discretion and are assumed to reprice more slowly in a rising or declining interest rate environment and usually reprice at a rate less than the change in market rates. The effects of certain balance sheet attributes, such as fixed-rate loans, variable-rate loans that have reached their floors, and the volume of 87 noninterest-bearing deposits as a percentage of earning assets, impact our assumptions and consequently the results of our NII simulation 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 following table presents as of December 31, 2016, 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: December 31, 2016 Interest Rate Scenario: Forecasted Net Interest Income (Tax Equivalent) Percentage Change From Base Forecasted Net Interest Margin Change Forecasted Net Interest Margin From Base Up 300 basis points . . . . . . . . . . . . . . . . . . . . . . . .

The $28.5 million increase in year 1 NII was due primarily to a $936 million increase in the loan and lease portfolio balance and a four basis point increase in base case net interest margin. In addition to parallel interest rate shock scenarios, we also model various alternative rate vectors that are viewed as more likely to occur in a typical monetary policy tightening cycle. One such scenario provides for market rates to increase during the next six months in accordance with the forward yield curve and thereafter to increase by 25 basis points every six months. The expected first year NII under this alternative rising rate scenario would be approximately 0.7% lower than the base case. Of the $15.5 billion of total loans in the portfolio, $11.0 billion have variable interest rate terms (excluding hybrid loans discussed below). At December 31, 2016, $8.1 billion of these variable-rate loans have a loan rate higher than their floor rate, which allows them to reprice upwards at their next reprice date upon an increase in their index. Approximately 67% of the total variable-rate loans have a LIBOR index rate. The following table presents variable-rate loans at their floors and the amounts for which the fully- indexed rates would rise off of the floors and reprice as a result of the rate increases shown: December 31, 2016 Cumulative Amount of Variable-Rate Loans Rate Increase Needed to Reprice (Dollars in millions) $2,649 $2,804 $2,928 $2,935 0 - 100 bps 101 - 200 bps 201 - 300 bps > 300 bps 88 Additionally, certain variable-rate hybrid loans do not immediately reprice because the loans contain an initial fixed-rate period before they become variable. The cumulative amounts of hybrid loans that would switch from being fixed-rate to variable-rate, because the initial fixed-rate term would expire, were approximately $120.0 million, $321.0 million, and $519.0 million in the next one, two, and three years. Market Value of Equity We measure the impact of market interest rate changes on the net present value of estimated cash flows from our assets, liabilities and off-balance sheet items, defined as the market value of equity, using our MVE 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 include various assumptions regarding cash flows and interest rates and are by their nature forward-looking and inherently uncertain. The MVE 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, 2016. The following table shows the projected change in the market value of equity for the set of rate scenarios presented as of December 31, 2016: December 31, 2016 Interest Rate Scenario: Projected Market Value of Equity Dollar Change From Base Percentage Change From Base Percentage of Total Assets (Dollars in millions) Up 300 basis points . . . . . . . . . . . . . . . . .

The projected market value of equity increased by $438 million while our overall MVE sensitivity profile has remained relatively unchanged. The increase in base case market value of equity was due primarily to: (1) an $81 million increase in the book value of stockholders’ equity, (2) a $250 million decrease in the mark-to-market adjustment for total deposits due to the higher forward yield curve and a shift in the deposit mix from time deposits to non-maturity deposits with longer duration, and (3) a $100 million increase in the mark-to-market adjustment for loans and leases due to lower credit spreads used for the valuation. 89 ITEM 8.

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, 2016, 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 (2013) 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, 2016, 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, 2016. The report, which expresses an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2016, is included in this Item under the heading ‘‘Report of Independent Registered Public Accounting Firm.’’ 91 Report of Independent Registered Public Accounting Firm The Board of Directors and Stockholders PacWest Bancorp: We have audited the accompanying consolidated balance sheets of PacWest Bancorp and subsidiaries as of December 31, 2016 and 2015, and the related consolidated statements of earnings, comprehensive income, changes in stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2016. We also have audited PacWest Bancorp’s internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control— Integrated Framework (2013) 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. 92 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, 2016 and 2015, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2016, 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, 2016, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. /s/ KPMG LLP Los Angeles, California February 28, 2017 93 PACWEST BANCORP AND SUBSIDIARIES CONSOLIDATED BALANCE SHEETS December 31, 2016 2015 (Dollars in thousands, except par value amounts) ASSETS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES PacWest Bancorp, a Delaware corporation, is a bank holding company registered under the BHCA, with our corporate headquarters located in Los Angeles, California. Our principal business is to serve as the holding company for our wholly-owned subsidiary, Pacific Western Bank. References to ‘‘Pacific Western’’ or the ‘‘Bank’’ refer to Pacific Western Bank together with its wholly-owned subsidiaries. References to ‘‘we,’’ ‘‘us,’’ or the ‘‘Company’’ refer to PacWest Bancorp together with its subsidiaries on a consolidated basis. When we refer to ‘‘PacWest’’ or to the ‘‘holding company,’’ we are referring to PacWest Bancorp, the parent company, on a stand-alone basis. We are focused on relationship-based business banking to small, middle-market and venture- backed businesses nationwide. The Bank offers a broad range of loan and lease and deposit products and services through 77 full-service branches located throughout the State of California, one branch located in Durham, North Carolina, and several loan production offices located in cities across the country. We provide commercial banking services, including real estate, construction, and commercial loans, and comprehensive deposit and treasury management services to small and middle-market businesses. We offer additional products and services through our CapitalSource and Square 1 Bank divisions. Our CapitalSource Division provides cash flow, asset-based, equipment, and real estate loans and treasury management services to established middle market businesses on a national basis. Our Square 1 Bank Division offers a comprehensive suite of financial services focused on entrepreneurial businesses and their venture capital and private equity investors, with offices located in key innovation hubs across the United States. In addition, we provide investment advisory and asset management services to select clients through Square 1 Asset Management, Inc., a wholly-owned subsidiary of the Bank and a SEC-registered investment adviser. When we refer to ‘‘CapitalSource Inc.,’’ we are referring to the company acquired on April 7, 2014 and when we refer to the ‘‘CapitalSource Division,’’ we are referring to a division of Pacific Western Bank that specializes in middle-market lending on a nationwide basis. We generate our revenue primarily from interest received on loans and leases and, to a lesser extent, from interest received on investment securities, and fees received in connection with deposit services, extending credit and other services offered, including foreign exchange services. Our major operating expenses are the interest paid by the Bank on deposits and borrowings, compensation and general operating expenses. We have completed 28 acquisitions from May 1, 2000 through December 31, 2016, including the acquisition of Square 1 on October 6, 2015. Our acquisitions have been accounted for using the acquisition method of accounting and, accordingly, the operating results of the acquired entities have been included in the consolidated financial statements from their respective acquisition dates. See Note 4. Acquisitions for more information about the Square 1 acquisition and the CapitalSource Inc. merger. On March 31, 2016, we sold our PWEF leasing unit in Midvale, Utah, including approximately $139 million of outstanding lease balances. 99 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) (a) Accounting Standard Adopted in 2015 Effective January 1, 2015, the Company adopted ASU 2014-01, new accounting guidance for investments in affordable housing projects that qualify for the low-income housing tax credit. As a result of the adoption of this new guidance, the Company made an accounting policy election to amortize the initial cost of its qualifying investments in proportion to the tax credits and other benefits received and to present the amortization as a component of income tax expense, referred to as the proportional amortization method. Previously, investments in low-income housing tax credits were accounted for under the equity method and such amortization was presented in other expense. The guidance was required to be applied retrospectively and accordingly, prior period amounts for other expense and tax expense have been revised to conform to the current period presentation. The retrospective application of the adoption of the new accounting guidance for the proportional amortization method resulted in a cumulative effect on retained earnings of a reduction of $195,000. (b) 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. (c) 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 allowance for credit losses, the carrying value of intangible assets, and the realization of deferred tax assets. As described in Note 4. Acquisitions below, we completed the Square 1 acquisition on October 6, 2015 and the CapitalSource Inc. merger on April 7, 2014. The acquired assets and liabilities in each of these acquisitions were measured at their estimated fair values. Management made significant estimates and exercised significant judgment in estimating such fair values and accounting for the acquired assets and assumed liabilities in each of these transactions. (d) Cash and Cash Equivalents For purposes of the consolidated statements of cash flows, cash and cash equivalents consist of cash, due from banks, and interest-earning deposits in financial institutions. Interest-earning assets in financial institutions represent mostly cash held at the FRBSF, the majority of which is immediately available. 100 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) (e) Investment Securities 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. As a result, 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 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. Declines in the fair value of debt securities classified as available-for-sale are reviewed to determine whether the impairment is other-than-temporary. This review considers a number of factors, including the severity of the decline in fair value, current market conditions, historical performance of the security, risk ratings and the length of time the security has been in an unrealized loss position. If we do not expect to recover the entire amortized cost basis of the security, then an other-than-temporary impairment is considered to have occurred. The cost basis of the security is written down to its estimated fair value and the amount of the write-down is recognized through a charge to earnings. Investments in FHLB stock are carried at cost and evaluated regularly for impairment. FHLB stock is expected to be redeemed at par and is a required investment based on measurements of the Bank’s assets and/or borrowing levels. (f) Loans and Leases Originated loans. Loans are originated by the Company with the intent to hold them for investment and are stated at the principal amount outstanding, net of unearned income. Unearned income includes deferred unamortized nonrefundable loan fees and direct loan origination costs. Net deferred fees or costs are recognized as an adjustment to interest income over the contractual life of the loans using the effective interest method or taken into income when the related loans are paid off or sold. The amortization of loan fees or costs is discontinued when a loan is placed on nonaccrual status. Interest income is recorded on an accrual basis in accordance with the terms of the respective loan. Purchased loans. Purchased loans are stated at the principal amount outstanding, net of unearned discounts or unamortized premiums. All loans acquired in our acquisitions are initially measured and recorded at their fair value on the acquisition date. A component of the initial fair value measurement is an estimate of the credit losses over the life of the purchased loans. Purchased loans are also evaluated for impairment as of the acquisition date and are accounted for as ‘‘acquired non-impaired’’ or ‘‘purchased credit impaired’’ loans. 101 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Acquired non-impaired loans. Acquired non-impaired loans are those loans for which there was no evidence of credit deterioration at their acquisition date and it was probable that we would be able to collect all contractually required payments. Acquired non-impaired loans, together with originated loans, are referred to as Non-PCI loans. Purchase discount or premium on acquired non-impaired loans is recognized as an adjustment to interest income over the contractual life of such loans using the effective interest method or taken into income when the related loans are paid off or sold. Purchased credit impaired loans. PCI loans are accounted for in accordance with ASC Subtopic 310-30, ‘‘Loans and Debt Securities Acquired with Deteriorated Credit Quality.’’ A purchased loan is deemed to be credit impaired when there is evidence of credit deterioration since its origination and it is probable at the acquisition date that collection of all contractually required payments is unlikely. We apply PCI loan accounting when we acquire loans deemed to be impaired, and as a general policy election when we acquire a portfolio of loans in a distressed bank acquisition. For PCI loans, at the time of acquisition 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’’). 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 PCI loan portfolios; such amount is subject to change over time based on the performance of such loans. The carrying value of PCI loans is reduced by payments received, both principal and interest, and increased by the portion of the accretable yield recognized as interest income. The excess of the 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. PCI loans that are contractually past due are still considered to be accruing and performing as long as there is an expectation that the estimated cash flows will be received. If the timing and amount of cash flows is uncertain, then cash payments received will be recognized as a reduction of the recorded investment. As part of the fair value process and the subsequent accounting, the Company aggregates PCI loans into pools having common credit risk characteristics such as 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. Leases. We provide equipment financing to our customers through a variety of lease arrangements. The most common arrangement is a direct financing (capital) lease. For direct financing leases, lease receivables are recorded on the balance sheet but the leased property is not, although we generally retain 102 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) legal title to the leased property until the end of each lease. Direct financing leases are stated at the net amount of minimum lease payments receivable, plus any unguaranteed residual value, less the amount of unearned income and net acquisition discount at the reporting date. Direct lease origination costs are amortized using the effective interest method over the life of the leases. Leases acquired in an acquisition are initially measured and recorded at their fair value on the acquisition date. Purchase discount or premium on acquired leases is recognized as an adjustment to interest income over the contractual life of the leases using the effective interest method or taken into income when the related leases are paid off. Direct financing leases are subject to our allowance for loans and leases. We also have operating leases where we purchase equipment which is then leased to our customers. We receive periodic rental income payments, which are recorded as noninterest income, and the equipment remains on our balance sheet and is depreciated according to our fixed asset accounting policy. Loans and Leases Held for Sale. As part of our management of the loans and leases held in our portfolio, we will transfer loans from held for investment to held for sale. Upon transfer, any associated allowance for loan and lease loss is charged off and the carrying value of the loan is adjusted to the lower of cost or estimated fair value. Gains or losses on the sale of these loans are recorded in noninterest income. Delinquent or past due loans and leases. Loans and leases 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. Nonaccrual loans and leases. When we discontinue the accrual of interest on a loan or lease it is designated as nonaccrual. We discontinue the accrual of interest on a loan generally when principal or interest payments are past due 90 days or when, in the opinion of management, there is a reasonable doubt as to collectability in the normal course of business. Loans with interest or principal past due 90 days may be accruing if the loans are concluded to be well-secured and in the process of collection; however, these loans are still reported as nonperforming loans. 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 collectable. Loans are restored to accrual status when the loans become both well-secured and are in the process of collection. Leases are designated as nonaccrual leases when the recognition of interest has been discontinued. The recognition of interest on leases is generally discontinued when a lessee’s payments are past due 90 days or when, in the opinion of management, there is a reasonable doubt as to collectability. Leases with payments past due 90 days may be accruing if the leases are concluded to be well-secured and in the process of collection; however, these leases are still reported as nonperforming leases. Interest on nonaccrual leases is subsequently recognized only to the extent that cash is received and the lease balance is deemed collectable. Leases are restored to accrual status when the leases become both well-secured and are in the process of collection. Impaired loans and leases. A loan or lease 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 or lease agreement. Impaired loans and leases include loans and leases on nonaccrual status and performing troubled debt 103 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) restructured loans. Income from impaired loans is recognized 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 when the loan’s principal balance is deemed collectable. We measure impairment of a loan or lease by using the estimated fair value of the collateral, less estimated costs to sell and other applicable costs, if the loan or lease is collateral-dependent and the present value of the expected future cash flows discounted at the loan’s or lease’s effective interest rate if the loan or lease is not collateral-dependent. The impairment amount on a collateral-dependent loan or lease is charged-off, and the impairment amount on a loan that is not collateral-dependent is generally recorded 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 that we otherwise would not consider under our normal lending policies. 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 modifications of criticized loans are evaluated to determine whether such modifications are troubled debt restructurings as outlined under ASC Subtopic 310-40, ‘‘Troubled Debt Restructurings by Creditors.’’ Loans restructured with an interest rate equal to or greater than that of a new loan with comparable market risk at the time the loan is modified may be excluded from certain 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 of time, 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 maturity extensions, 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 or based on the fair value of the collateral if the loan is collateral-dependent. (g) Allowances for Credit Losses Allowance for credit losses on Non-PCI loans and leases. The allowance for credit losses on Non-PCI loans and leases is the combination of the allowance for loan and lease losses and the reserve for unfunded loan commitments. The allowance for loan and lease losses is reported as a reduction of outstanding loan and lease balances and the reserve for unfunded loan commitments is included within ‘‘Accrued interest payable and other liabilities’’ on the consolidated balance sheets The following discussion is for Non-PCI loans and leases and the related allowance for credit losses. For the allowance policy on purchased credit impaired loans and leases, refer to ‘‘—Allowance for loan losses on PCI loans.’’ For loans and leases acquired and measured at fair value and deemed non-impaired on the acquisition date, our allowance methodology measures deterioration in credit quality or other inherent risks related to these acquired assets that arise after the acquisition date. 104 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) The allowance for credit losses is maintained at a level deemed appropriate by management to adequately provide for known and inherent risks in the loan and lease portfolio and other extensions of credit at the balance sheet date. The allowance is based upon our review of the credit quality of the loan and lease portfolio, which includes loan and lease payment trends, borrowers’ compliance with loan agreements, borrowers’ current and budgeted financial performance, collateral valuation trends, and current economic factors and external conditions that may affect our borrowers’ ability to make payments to us in accordance with contractual terms. Loans and leases that are deemed to be uncollectable are charged off and deducted from the allowance. The provision for loan and lease losses and recoveries on loans and leases previously charged off are added to the allowance. The allowance for loan and lease losses contains a general reserve component for loans and leases not considered impaired and a specific reserve component for loans and leases determined to be impaired. A loan or lease is considered impaired when it is probable that we will be unable to collect all amounts due according to the original contractual terms of the agreement. We assess our loans for impairment on an ongoing basis using certain criteria such as payment performance, borrower reported financial results and budgets, and other external factors when appropriate. We measure impairment of a loan based upon the fair value of the loan’s collateral if the loan is collateral-dependent or the present value of cash flows, discounted at the loan’s effective interest rate, if the loan is not collateral- dependent. We measure impairment of a lease based upon the present value of the scheduled lease and residual cash flows, discounted at the lease’s effective interest rate. To the extent a loan or lease balance exceeds the estimated collectable value, a specific reserve or charge-off is recorded depending upon either the certainty of the estimate of loss or the fair value of the loan’s collateral if the loan is collateral-dependent. Smaller balance loans (under $250,000), with a few exceptions for certain loan types, are generally not assessed individually for impairment but are evaluated collectively. The methodology we use to estimate the general reserve component of our allowance for credit losses considers both objective and subjective criteria. The objective criteria uses our actual historical loan and lease charge-off experience on pools of similar loans and leases to establish loss factors that are applied to our current loan and lease balances to estimate inherent credit losses. The estimation of the allowance for credit losses at December 31, 2016 considered actual historical loan and lease charge-off experience over a 27-quarter look-back period starting with the first quarter of 2010. This look-back period is inclusive of the average timeframe over which charge-offs typically occur following loan or lease origination. The estimation of the allowance for credit losses at December 31, 2015 considered actual historical loan and lease charge-off experience over a 23-quarter look-back period starting with the first quarter of 2010. The increase in the historical look-back period from a 23-quarter look-back period at December 31, 2015 to 27 quarters at December 31, 2016 allows the look-back period to capture sufficient loss observations and is relevant to the current portfolio; in a good economic cycle with less frequent loss events, a longer look-back period is more appropriate to reflect the level of incurred losses. When estimating the general reserve component for the various pools of similar loan types, the loss factors applied to the loan pools consider the current credit risk ratings, giving greater weight to loans with more adverse credit risk ratings. We recognize that the determination of the allowance for credit losses is sensitive to the assigned credit risk ratings and inherent loss rates at any given point in time. To ensure the accuracy of our credit risk ratings, an independent credit review function assesses the appropriateness of the credit risk ratings assigned to loans on a regular basis. 105 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) The qualitative criteria we consider when establishing the loss factors include the following: (cid:129) current economic trends and forecasts; (cid:129) current commercial real estate values, performance trends, and overall outlook in the markets where we lend; (cid:129) legal and regulatory matters that could impact our borrowers’ ability to repay our loans and leases; (cid:129) loan and lease portfolio composition and any loan concentrations; (cid:129) current lending policies and the effects of any new policies or policy amendments; (cid:129) loan and lease production volume and mix; (cid:129) loan and lease portfolio credit performance trends; (cid:129) results of our independent credit review; and (cid:129) changes in management related to credit administration functions. We estimate the reserve for unfunded commitments using the same loss factors as used for the allowance for loan and lease losses and is computed based on the expected usage of the unfunded commitments. The credit risk ratings assigned to every loan and lease are either ‘‘pass,’’ ‘‘special mention,’’ ‘‘substandard’’ or ‘‘doubtful’’ and defined as follows: (cid:129) Pass: Loans and leases classified as ‘‘pass’’ are not adversely classified and collection and repayment in full is expected. (cid:129) Special Mention: Loans and leases classified as ‘‘special mention’’ have a potential weakness that requires management’s attention. If not addressed, these potential weaknesses may result in further deterioration in the borrower’s ability to repay the loan or lease. (cid:129) Substandard: Loans and leases classified as ‘‘substandard’’ have a well-defined weakness or weaknesses that jeopardize the collection of the debt. They are characterized by the possibility that we will sustain some loss if the weaknesses are not corrected. (cid:129) Doubtful: Loans and leases classified as ‘‘doubtful’’ have all the weaknesses of those classified as ‘‘substandard,’’ with the additional trait that the weaknesses make collection or repayment in full highly questionable and improbable. In addition, we may refer to the loans and leases with assigned credit risk ratings of ‘‘substandard’’ and ‘‘doubtful’’ together as ‘‘classified’’ loans and leases. For further information on classified loans and leases, see Note 7. Loans and Leases. Management believes the allowance for credit losses is appropriate for the known and inherent risks in our Non-PCI loan and lease portfolio and the credit risk ratings and inherent loss rates currently assigned are appropriate. It is possible that others, given the same information, may at any point in time reach different conclusions that could result in a significant impact to the Company’s financial statements. In addition, current credit risk ratings are subject to change as we continue to 106 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) monitor our loans and leases. To the extent we experience, for example, increased levels of borrower loan defaults, borrower noncompliance with our loan agreements, adverse changes in collateral values, or negative changes in economic and business conditions that adversely affect our borrowers, our classified loans and leases may increase. Higher levels of classified loans and leases generally result in increased provisions for credit losses and an increased allowance for credit losses. Although we have established an allowance for credit losses that we consider appropriate, there can be no assurance that the established allowance will be sufficient to absorb future losses. 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 loan losses on PCI loans. We measure the allowance for loan losses for PCI loans at the end of each financial reporting period based on expected cash flows of the PCI loans. Decreases or (increases) in the amount and changes in the timing of expected cash flows on the PCI loans as of the financial reporting date compared to those previously estimated are usually recognized by recording a provision or a (negative provision) for credit losses on such loans. For example, a decrease in the expected cash flows of PCI loans would result in an additional reserve requirement and a provision for PCI loan credit losses would be recorded. (h) 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 7 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. (i) Foreclosed Assets Foreclosed assets include OREO and repossessed non-real estate assets. Foreclosed assets are 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 a foreclosed assets valuation allowance. Subsequent increases in the fair value of the asset less selling costs reduce the foreclosed assets valuation allowance, but not below zero, and are credited to noninterest expense. Gains and losses on the sale of foreclosed assets and operating expenses of such assets are also included in noninterest expense. (j) 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 107 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) 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 and liabilities, net of valuation allowances, are grouped together and reported net on the consolidated balance sheets. 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 positions, 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 are required to record a valuation allowance on our deferred tax assets by charging earnings. The Company also evaluates existing valuation allowances periodically to determine if sufficient evidence exists to support an increase or reduction in the allowance. (k) Goodwill and Other Intangible Assets Goodwill and other intangible assets arise from the acquisition method of accounting for business combinations. Goodwill 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 generated from business combinations and deemed to have indefinite lives are not subject to amortization and are instead tested for impairment at least annually. Impairment exists when the carrying value of the goodwill exceeds its implied fair value. An impairment loss would be recognized in an amount equal to that excess as a charge to noninterest expense in the consolidated statement of earnings. Intangible assets with estimable useful lives are amortized over such useful lives to their estimated residual values and reviewed for impairment at least quarterly. CDI and CRI are recognized apart from goodwill at the time of acquisition based on market valuations. In preparing such valuations, variables considered included 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 7 years. The amortization expense represents the estimated decline in the value of the underlying deposits or customer relationships acquired. 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, then the intangible asset is reduced to such fair value; an impairment loss for such amount would be recognized as a charge to noninterest expense in the consolidated statement of earnings. 108 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) (l) Stock-Based Compensation The Company issues stock-based compensation instruments consisting of TRSAs and PRSUs. Compensation expense related to TRSAs 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. Compensation expense related to PRSUs is based on the fair value of the underlying stock on the award date and is amortized over the vesting period using the straight-line method unless it is determined that: (1) attainment of the financial metrics is less than probable, in which case a portion of the amortization is suspended, or (2) attainment of the financial metrics is improbable, in which case a portion of the previously recognized amortization is reversed and also suspended. In the case where the performance target for the PRSU’s is based on a market condition (such as total shareholder return), the amortization is neither reversed nor suspended if it is subsequently determined that the attainment of the performance target is less than probable or improbable. Unvested TRSAs participate with common stock in any dividends declared and paid. Dividends paid on unvested TRSAs expected to vest and the related tax benefits are included as a net reduction to stockholders’ equity. Dividends paid on unvested TRSAs not expected to vest are charged to compensation expense. Unvested PRSUs participate with common stock in any dividends declared, but are paid only on the shares which ultimately vest, if any, at the end of the three-year performance period. At the time of vesting, the vested shares are entitled to receive cumulative dividends declared and paid during the three-year performance period. Such dividends are accrued during the three-year performance period at the estimated level of dividends to be received by the award holder. (m) Derivative Instruments Our derivative contracts primarily manage the foreign currency risk associated with certain assets. As of December 31, 2016, all of our derivatives were held for risk management purposes and none were designated as accounting hedges. The objective is to manage the uncertainty of future foreign exchange rate fluctuations. These forward exchange contracts provide for a fixed exchange rate which has the effect of reducing or eliminating changes to anticipated cash flows to be received from loan transactions denominated in foreign currencies as the result of changes to exchange rates. Our derivatives are recorded in other assets or other liabilities, as appropriate. The changes in fair value of our derivatives and the related interest are recognized in other income. At December 31, 2016, our derivative contracts had a notional value of $79.8 million. Derivative instruments expose us to credit risk in the event of nonperformance by counterparties to such agreements. This risk exposure consists primarily of the termination value of agreements where we are in a favorable position. We manage the credit risk associated with various derivative agreements through counterparty credit review and monitoring procedures. (n) Investments That Do Not Have Readily Determinable Fair Values Investments in common or preferred stock that are not publicly traded that do not have a readily determinable fair value in which we have the ability to significantly influence the operating and financial policies of an investee are accounted for pursuant to the equity method of accounting. This is generally presumed to exist when we own between 20% and 50% of a corporation, or when we own greater than 5% of a limited partnership or similarly structured entity. Our investment carrying values 109 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) are included in other assets and our share of earnings and losses in equity method investees is included in other income. If we do not have significant influence over the investee, the cost method is used to account for the equity interest. Investments accounted for using the cost or equity method of accounting are evaluated for other-than-temporary impairment quarterly. An impairment exists when the estimated fair value for each investment is less than its carrying value. If an impairment exists, then such impairment is evaluated for whether it is considered to be temporary or other-than-temporary. In determining whether an other-than-temporary decline in value exists, management evaluates information such as budgets, business plans, and financial statements of the investee in addition to quoted market prices, if any. Factors indicative of an other-than-temporary decline in value include, but are not limited to, recurring operating losses and credit defaults. If we determine that an investment has sustained an other-than-temporary decline in its value, then the equity interest is written down to its estimated fair value through other income and a new carrying value for the investment is established. Realized gains or losses resulting from the sale of investments are calculated using the specific identification method and are included in other income. (o) 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. (p) 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. (q) 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. 110 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) (r) Business Segments We regularly assess our strategic plans, operations and reporting structures to identify our reportable segments. Changes to our reportable segments are expected to be infrequent. As of December 31, 2016, we operated as one reportable segment. The factors considered in making this determination include the nature of products and offered services, geographic regions in which we operate, the applicable regulatory environment, and the discrete financial information reviewed by our key decision makers. Through our network of banking offices nationwide, our entire operations provide relationship-based banking products, services and solutions for small to mid-sized companies, entrepreneurial businesses and their venture capital and private equity investors, real estate investors, professionals and other individuals. Our products and services include commercial real estate, multi- family, commercial business, construction and land, consumer and government-guaranteed small business loans, business and personal deposit products, and treasury cash management services. (s) Recently Issued Accounting Standards In May 2014, the FASB issued ASU 2014-09, ‘‘Revenue Recognition (Topic 606): Revenue from Contracts with Customers.’’ ASU 2014-09 requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in GAAP when it becomes effective. The standard permits the use of either the retrospective or cumulative effect transition method. In August 2015, the FASB issued ASU 2015-14, ‘‘Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,’’ which deferred the effective date of ASU 2014-09 to annual and interim periods beginning after December 15, 2017, while earlier application is permitted only for annual and interim periods beginning after December 31, 2016. The Company has completed the assessment phase of implementing this new standard. In the assessment phase, the Company determined which revenue streams are within the scope and those that are excluded from the scope of the new standard. Substantially all of the Company’s revenues are excluded from the scope of the new standard. For the revenue streams determined to be within the scope of the new standard, the Company examined a sample of customer contracts to determine the appropriate accounting for those contracts under the new standard. The Company is currently evaluating the need for any accounting or operational changes related to implementing the requirements of the new standard. The Company has not yet selected a transition method and does not expect the provisions of ASU 2014-09 to have a material impact on its consolidated financial position or results of operations. The Company will adopt this standard effective January 1, 2018. In January 2016, the FASB issued ASU 2016-01, ‘‘Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities,’’ which will significantly change the income statement impact of equity investments and the recognition of changes in fair value of financial liabilities when the fair value option is elected. For equity investments with readily determinable fair values, entities must measure these investments at fair value and recognize changes in fair value in net income. For equity investments without readily determinable fair values, entities have the option to either measure these investments at fair value or at cost, adjusted for changes in observable prices, minus impairment. Changes in measurement under either alternative must be recognized in net income. ASU 2016-01 will be effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted only for the provisions related to the recognition of 111 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) changes in fair value of financial liabilities, which does not apply to the Company. The Company does not expect the provisions of ASU 2016-01 to have a material impact on its consolidated financial position or results of operations. In February 2016, the FASB issued ASU 2016-02, ‘‘Leases (Topic 842),’’ which, among other things, requires lessees to recognize most leases on-balance sheet, which will result in an increase in their reported assets and liabilities. Lessor accounting remains substantially similar to current U.S. GAAP. ASU 2016-02 supersedes Topic 840, Leases. ASU 2016-02 is effective for annual and interim periods in fiscal years beginning after December 15, 2018 and mandates a modified retrospective transition method for all entities. The Company is evaluating the effect that ASU 2016-02 will have on its financial statements and related disclosures. In March 2016, the FASB issued ASU 2016-07, ‘‘Simplifying the Transition to the Equity Method of Accounting,’’ which eliminates the requirement for an investor to retroactively apply the equity method when its increase in ownership interest (or degree of influence) in an investee triggers equity method accounting. ASU 2016-07 is effective for interim and annual periods in fiscal years beginning after December 15, 2016, however, earlier application was permitted. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. ASU 2016-07 does not require additional disclosures at transition. There will be no material impact on the Company’s financial statements and related disclosures on a prospective basis from the requirements of ASU 2016-07. In March 2016, the FASB issued ASU 2016-09, ‘‘Improvements to Employee Share-Based Payment Accounting,’’ which is intended to improve the accounting for share-based payment transactions as part of the FASB’s simplification initiative. ASU 2016-09 changes aspects of the accounting for share-based payment award transactions, including: (1) accounting for income taxes; (2) classification of excess tax benefits on the statement of cash flows; (3) forfeitures; (4) minimum statutory tax withholding requirements; and (5) classification of employee taxes paid on the statement of cash flows when an employer withholds shares for tax-withholding purposes. The Company adopted ASU 2016-09 effective January 1, 2017. The recognition of excess tax benefits and deficiencies in the income statement was adopted prospectively. The adoption of ASU 2016-09 did not have a material impact on the Company’s financial statements upon adoption. We expect the requirements of ASU 2016-09 to result in fluctuations in our effective tax rate from period to period based upon the timing of share-based award vestings. In June 2016, the FASB issued ASU 2016-13, ‘‘Measurement of Credit Losses on Financial Instruments,’’ which significantly changes the way entities recognize impairment of many financial assets. Currently, the impairment model is based on incurred losses, and investments are recognized as impaired when there is no longer an assumption that future cash flows will be collected in full under the originally contracted terms. Under the current expected credit loss (CECL) model, the new standard requires immediate recognition of estimated credit losses expected to occur over the remaining life of the asset. The Company is reviewing software to meet the requirements of ASU-2016-13. The Company is planning to engage a third-party vendor and commence early-stage model development in 2017. ASU 2016-13 is effective for interim and annual periods in fiscal years beginning after December 15, 2019. The Company is evaluating the effect that ASU 2016-13 will have on its consolidated financial position or results of operations. 112 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) In August 2016, the FASB issued ASU 2016-15, ‘‘Classification of Certain Cash Receipts and Cash Payments,’’ which addressed eight issues related to the statement of cash flows, including proceeds from the settlement of BOLI policies. ASU 2016-15 is effective for interim and annual periods in fiscal years beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. If an entity early adopts ASU 2016-15 in an interim period, adjustments should be reflected as of the beginning of the fiscal year that includes the interim period. An entity that elects early adoption must adopt all of the amendment in the same period. Entities should apply ASU 2016-15 using a retrospective transition method to each period presented. If it is impracticable for an entity to apply ASU 2016-15 retrospectively for some of the issues, it may apply the amendments for those issues prospectively as of the earliest date practicable. ASU 2016-15 will result in some changes in classification in the consolidated statements of cash flows, which the Company does not expect will be significant, and will not have any impact on its consolidated financial position or results of operations. In October 2016, the FASB issued ASU 2016-16, ‘‘Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory,’’ which requires entities to recognize at the transaction date the income tax consequences of intercompany asset transfers other than inventory. ASU 2016-16 is effective for interim and annual periods in fiscal years beginning after December 15, 2017. Early adoption is permitted, but only at the beginning of an annual period for which no financial statements (interim or annual) have already been issued or made available for issuance. The Company is evaluating the effect that ASU 2016-16 will have on its financial statements and related disclosures. In October 2016, the FASB issued ASU 2016-17, ‘‘Consolidation (Topic 810): Interests Held Through Related Parties That Are Under Common Control,’’ which a single decision maker or service provider, in evaluating whether it is the primary beneficiary, to consider on a proportionate basis indirect interests held through related parties under common control. ASU 2016-17 is effective for interim and annual periods in fiscal years beginning after December 15, 2016. The Company does not expect ASU 2016-17 to have a material impact on its financial condition or results of operations. In January 2017, the FASB issued ASU 2017-04, ‘‘Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,’’ which intends to simplify goodwill impairment testing by eliminating the second step of the analysis under which the implied fair value of goodwill is determined as if the reporting unit were being acquired in a business combination. ASU 2017-04 instead requires entities to compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for any amount by which the carrying amount exceeds the reporting unit’s fair value, to the extent that the loss recognized does not exceed the amount of goodwill allocated to that reporting unit. ASU 2017-04 must be applied prospectively and is effective for the Company on January 1, 2020. Early adoption is permitted. The Company does not expect ASU 2017-04 to have a material impact on its financial condition or results of operations. NOTE 2. DISCONTINUED OPERATIONS Discontinued operations include the income and expense related to Electronic Payment Services (‘‘EPS’’), a discontinued division of the Bank acquired in connection with the FCAL acquisition on May 31, 2013. Liabilities of the EPS division, which were $12.5 million and $15.9 million at December 31, 2016 and 2015, consisted primarily of noninterest-bearing deposits and are included in the consolidated balance sheets under the caption ‘‘Accrued interest payable and other liabilities.’’ 113 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 3. RESTRICTED CASH BALANCES The Company is required to maintain reserve balances with the FRBSF. 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 FRBSF for the years ended December 31, 2016 and 2015 were $67.7 million and $27.7 million. NOTE 4.

ACQUISITIONS (Continued) Square 1 Financial, Inc. Acquisition We acquired Square 1 on October 6, 2015. As part of the acquisition, Square 1 Bank, a wholly- owned subsidiary of Square 1, merged with and into Pacific Western. At closing, we formed the Square 1 Bank Division of Pacific Western to focus on providing a comprehensive suite of financial services to entrepreneurial businesses and their venture capital and private equity investors nationwide. When we refer to ‘‘Square 1,’’ we are referring to the company acquired on October 6, 2015, and when we refer to the ‘‘Square 1 Bank Division,’’ we are referring to a division of Pacific Western. We completed this acquisition to increase our core deposits, expand our nationwide lending platform, and increase our presence in the technology and life-sciences credit markets. The Square 1 acquisition has been accounted for under the acquisition method of accounting. We acquired $4.6 billion of assets and assumed $3.8 billion of liabilities upon closing of the acquisition. The assets and liabilities, both tangible and intangible, were recorded at their estimated fair values as of the acquisition date. We made significant estimates and exercised significant judgment in estimating fair values and accounting for such acquired assets and liabilities. The application of the acquisition method of accounting resulted in goodwill of $446.1 million. All of the recognized goodwill is non-deductible for tax purposes. CapitalSource Inc. Merger We acquired CapitalSource Inc. on April 7, 2014. As part of the merger, CapitalSource Bank, a wholly-owned subsidiary of CapitalSource Inc., merged with and into Pacific Western. At closing, we formed the CapitalSource Division of the Bank. We completed the merger in order to increase our loan and lease generation capabilities and to diversify our loan portfolio. The application of the acquisition method of accounting resulted in goodwill of $1.5 billion. All of the recognized goodwill is non-deductible for tax purposes. NOTE 5.

GOODWILL AND OTHER INTANGIBLE ASSETS (Continued) Goodwill adjustments include the finalization of the acquired Square 1 net tax assets and the reduction of goodwill in connection with the sale of the PWEF leasing unit. The finalization of the day 1 fair value of the acquired tax assets is due to completion of the 2015 tax returns. Through the sale of the PWEF leasing unit on March 31, 2016, $0.5 million of goodwill was allocated to this business group; such goodwill reduction is included in the $0.7 million loss on sale of the PWEF leasing unit and included in ‘‘Other income’’ in the condensed consolidated statements of earnings. We perform our annual goodwill impairment testing in the fourth quarter each year. In the fourth quarter of 2016 we evaluated the carrying value of our goodwill and determined that it was not impaired. Our intangible assets with definite lives are CDI and CRI. CDI and CRI are amortized over their respective estimated useful lives and reviewed for impairment at least quarterly. The amortization expense represents the estimated decline in the value of the underlying deposits or loan and lease customers acquired. The weighted average amortization period remaining for all of our CDI and CRI as of December 31, 2016 is 5.3 years. The estimated aggregate amortization expense related to these intangible assets for each of the next five years is $11.5 million for 2017, $8.8 million for 2018, $6.7 million for 2019, $4.7 million for 2020 and $3.0 million for 2021.

Fair Value Measurements for information on fair value measurements and methodology. As of December 31, 2016, securities available-for-sale with a carrying value of $425.5 million were pledged as collateral for borrowings, public deposits and other purposes as required by various statutes and agreements. Realized gains or losses in the statement of earnings resulting from the sale of securities are calculated using the specific identification method and included in gain on sale of securities. During the year ended December 31, 2016, we sold $384.0 million of securities available-for-sale for a gross realized gain of $11.1 million and a gross realized loss of $1.6 million. During the year ended December 31, 2015, we sold $208.4 million of securities available-for-sale for a gross realized gain of $4.5 million and a gross realized loss of $0.7 million. We also sold $823.8 million of the $2.2 billion of securities obtained in the Square 1 acquisition for no gain or loss as they were marked to fair value at the time of acquisition. During the year ended December 31, 2014, we sold $138.1 million of securities available-for-sale for a gross realized gain of $4.8 million. We also sold $322.7 million of the $382.8 million of securities obtained in the CapitalSource Inc. merger for no gain or loss as they were marked to fair value at the time of acquisition. During the years ended December 31, 2016, 2015 and 2014 accumulated other comprehensive income included $(16.2) million, $3.6 million and $32.6 million of net unrealized after-tax (losses) gains. 117 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 6.

Accordingly, we determined the securities were temporarily impaired and we did not recognize such impairment in the consolidated statements of earnings. Although we periodically sell securities for portfolio management purposes, we do not foresee having to sell any temporarily impaired securities strictly for liquidity needs and believe that it is more likely than not we would not be required to sell any temporarily impaired securities before recovery of their amortized cost. 118 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 6.

In addition, expected maturities may differ from contractual maturities because obligors and/or issuers may have the right to call or prepay obligations with or without call or prepayment penalties. FHLB Stock In connection with outstanding FHLB advances, the Bank owned FHLB stock carried at cost of $21.9 million and $19.7 million at December 31, 2016 and 2015. At December 31, 2016 and 2015, the Bank was required to own FHLB stock at least equal to 2.7% of outstanding FHLB advances. During the year ended December 31, 2016, FHLB stock increased by $2.2 million due to $15.6 million in purchases, offset partially by $13.4 million in redemptions. We evaluated the carrying value of our FHLB stock investment at December 31, 2016, and determined that it was not impaired. Our evaluation considered the long-term nature of the investment, the current financial and liquidity position of the FHLB, repurchase activity of excess stock by the FHLB at its carrying value, the return on the investment from recurring dividends, and our intent and ability to hold this investment for a period of time sufficient to recover our recorded investment.

LOANS AND LEASES The Company’s loan and lease portfolio includes originated and purchased loans and leases. Originated loans and leases and purchased loans and leases for which there was no evidence of credit deterioration at their acquisition date and it was probable that we would be able to collect all contractually required payments, are referred to collectively as Non-PCI loans. Purchased loans for which there was, at the acquisition date, evidence of credit deterioration since their origination and it was probable that collection of all contractually required payments was unlikely are referred to as PCI loans. Non-PCI loans are carried at the principal amount outstanding, net of deferred fees and costs, and in the case of acquired loans, net of purchase discounts and premiums. Deferred fees and costs and purchase discounts and premiums on acquired non-impaired loans are recognized as an adjustment to interest income over the contractual life of the loans primarily using the effective interest method or taken into income when the related loans are paid off or sold. PCI loans are accounted for in accordance with ASC Subtopic 310-30, ‘‘Loans and Debt Securities Acquired with Deteriorated Credit Quality.’’ For PCI loans, at the time of acquisition we (i) calculate the contractual amount and timing of undiscounted principal and interest payments (the ‘‘undiscounted contractual cash flows’’) and (ii) estimate the amount and timing of undiscounted expected principal and interest payments (the ‘‘undiscounted expected cash flows’’). The difference between the undiscounted contractual cash flows and the undiscounted expected cash flows is the nonaccretable difference. The difference between the undiscounted cash flows expected to be collected and the estimated fair value of the acquired loans is the accretable yield. The nonaccretable difference represents an estimate of the loss exposure of principal and interest related to the PCI loan portfolios; such amount is subject to change over time based on the performance of such loans. The carrying value of PCI loans is reduced by payments received, both principal and interest, and increased by the portion of the accretable yield recognized as interest income. 120 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 7.

BORROWINGS AND SUBORDINATED DEBENTURES (Continued) Interest payments made by the Company on subordinated debentures are considered dividend payments under FRB regulations. Bank holding companies, such as PacWest, are required to notify the FRB prior to declaring and paying a dividend to stockholders during any period in which quarterly and/or cumulative twelve-month net earnings are insufficient to fund the dividend amount, among other requirements. NOTE 12. COMMITMENTS AND CONTINGENCIES Lending Commitments The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit, and commitments to purchase equipment being acquired for lease to others. Those instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets. The contract or notional amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments. The following table presents a summary of the financial instruments described above as of the dates indicated: Loan commitments to extend credit . . . . . . . . . . . . . . . . . Standby letters of credit . . . . . . . . . . . . . . . . . . . . . . . . . .

Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. We provide standby letters of credit in conjunction with several of our lending arrangements and property lease obligations. Most guarantees expire within one year from the date of issuance. If a borrower defaults on its commitments subject to any letter of credit issued under these arrangements, we would be required to meet the borrower’s financial obligation but would seek repayment of that financial obligation from the borrower. In some cases, borrowers have pledged cash or investment securities as collateral with us under these arrangements. 138 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 12. COMMITMENTS AND CONTINGENCIES (Continued) In addition, we invest in low income housing project partnerships, which provide income tax credits, and in a few small business investment companies that call for capital contributions up to an amount specified in the partnership agreements. As of December 31, 2016 and 2015, we had commitments to contribute capital to these entities totaling $26.6 million and $19.2 million. We also had commitments to contribute up to an additional $2.8 million to private equity funds at December 31, 2016 and 2015. In addition, at December 31, 2016 we had a commitment to purchase approximately $12.6 million of loans, which commitment terminates in June 2017. The amount purchased will be based, in part, on the amount of portfolio paydowns which occur during the commitment period. Legal Matters In the ordinary course of our business, we are party to various legal actions, which we believe are incidental to the operation of our business. The outcome of such legal actions and the timing of ultimate resolution are inherently difficult to predict. In the opinion of management, based upon information currently available to us, any resulting liability, in addition to amounts already accrued, would not have a material adverse effect on the Company’s financial statements or operations. Kinde Durkee Investigation The United States Attorney’s Office for the Eastern District of California is conducting an investigation relating to the handling by First California Bank (‘‘FCB’’) of its banking relationship with Kinde Durkee. Ms. Durkee, who had maintained certain of her accounts with FCB, was convicted in 2012 of embezzling funds from certain California politicians, among others. FCB, a wholly-owned subsidiary of FCAL, was acquired by PacWest Bancorp and merged into Pacific Western Bank in May 2013. We understand that the investigation is focused on whether any civil or criminal laws were violated by FCB or its employees. Pacific Western is cooperating with the investigation. 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: (cid:129) Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets. (cid:129) 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 municipal securities, agency residential and commercial MBS, collateralized loan obligations, registered publicly rated private label CMOs and asset-backed securitizations. 139 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 13. FAIR VALUE MEASUREMENTS (Continued) (cid:129) Level 3: Inputs to a valuation methodology that are unobservable, supported by little or no market activity, and significant to the fair value measurement. These valuation methodologies generally include pricing models, discounted cash flow models, or a determination of fair value that requires significant management judgment or estimation. This category also includes observable inputs from a pricing service not corroborated by observable market data, and includes our non-rated private label CMOs, non-rated private label asset-backed securities, and equity warrants. We use fair value to measure certain assets and liabilities on a recurring basis, primarily securities available-for-sale and derivatives. For assets measured at the lower of cost or fair value, the fair value measurement criteria may or may not be met during a reporting period and such measurements are therefore considered ‘‘nonrecurring’’ for purposes of disclosing our fair value measurements. Fair value is used on a nonrecurring basis to adjust carrying values for impaired loans and other real estate owned and also to record impairment on certain assets, such as goodwill, core deposit intangibles, and other long-lived assets. The following tables present information on the assets measured and recorded at fair value on a recurring basis as of the dates indicated: Measured on a Recurring Basis: Total Level 1 Level 2 Level 3 (In thousands) Fair Value Measurements as of December 31, 2016 Securities available-for-sale: Residential MBS and CMOs: Agency MBS . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Cash and due from banks. The carrying amount is assumed to be the fair value because of the liquidity of these instruments. Interest-earning deposits in financial institutions. The carrying amount is assumed to be the fair value given the short-term nature of these deposits. Securities available-for-sale. Securities available-for-sale are measured and carried at fair value on a recurring basis. Unrealized gains and losses on available-for-sale securities are reported as a component of ‘‘Accumulated other comprehensive income’’ in the consolidated balance sheets. See Note 6. Investment Securities for further information on unrealized gains and losses on securities available-for-sale. Fair value for securities categorized as Level 1, which are publicly traded securities, are based on readily available quoted prices. In determining the fair value of the securities categorized as Level 2, we obtain a report from a nationally recognized broker-dealer detailing the fair value of each investment security we hold as of each reporting date. The broker-dealer uses observable market information to value our securities, with the primary source being a nationally recognized pricing service. We review the market prices provided by the broker-dealer for our securities for reasonableness 145 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 13. FAIR VALUE MEASUREMENTS (Continued) 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 non-rated private label CMOs, non-rated private label asset-backed securities, and equity warrants (collectively, ‘‘the Level 3 Securities’’) were categorized as Level 3 due in part to the inactive market for such securities. There is a wide range of prices quoted for our Level 3 Securities 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 relating to our Level 3 Securities to be a significant unobservable input. Our fair value estimate was based on either 1) 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, or 2) pricing estimates we obtained from brokers. We determined the reasonableness of the fair values by reviewing assumptions at the individual security level about prepayment, default expectations, estimated loss severity factors, and discount rates, all of which are not directly observable in the market. Significant changes in default expectations, loss severity factors, or discount rates, which occur all together or in isolation, would result in different fair value measurements. FHLB stock. Investments in FHLB stock are recorded at cost and measured for impairment quarterly. Ownership of FHLB stock is restricted to member banks and the securities do not have a readily determinable market value. Purchases and sales of these securities are at par value with the issuer. The fair value of investments in FHLB stock is equal to the carrying amount. Non-PCI loans and leases. As Non-PCI loans and leases 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 and leases with similar financial characteristics. Loans are segregated by type and further segmented into fixed and adjustable rate interest terms by credit risk categories. The fair value estimates do not take into consideration the value of the loan portfolio in the event the loans are sold outside the parameters of normal operating activities. The fair value of performing fixed-rate loans is estimating by discounting scheduled cash flows through the estimated maturity using estimated market prepayment speeds. The fair value of equipment leases is estimated by discounting scheduled lease and expected lease residual cash flows over their remaining term. The estimated market discount rates used for performing fixed-rate loans and equipment leases are current market rates for instruments with similar risk and 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. These methods and assumptions are not based on the exit price concept of fair value. Impaired Non-PCI loans. Nonaccrual loans and performing troubled debt restructured loans are considered impaired for reporting purposes and are measured and recorded at fair value on a non-recurring basis. Nonaccrual Non-PCI loans with an unpaid principal balance over $250,000 and all performing troubled debt restructured loans are reviewed individually for the amount of impairment, if any. Nonaccrual Non-PCI loans with an unpaid principal balance less than $250,000 are not individually assessed for impairment but are instead reserved for under our general reserve component. 146 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 13. FAIR VALUE MEASUREMENTS (Continued) To the extent a loan is collateral dependent, we measure such impaired loan based on the estimated fair value of the underlying collateral. The fair value of each loan’s collateral is generally based on estimated market prices from an independently prepared appraisal, which is then adjusted for the cost related to liquidating such collateral; such valuation inputs result in a nonrecurring fair value measurement that is categorized as a Level 2 measurement. The Level 2 measurement is based on appraisals obtained within the last 12 months and for which a charge-off was recognized or a change in the specific valuation allowance was made during the year ended December 31, 2016. 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 impaired Non-PCI loan balances shown above as measured on a non-recurring basis represent those nonaccrual and restructured loans for which impairment was recognized during the year ended December 31, 2016. The amounts shown as net losses include the impairment recognized during the year ended December 31, 2016, for the loan balances shown. Investments that do not have readily determinable fair values. Other investments accounted for under the cost or equity methods of accounting are carried at fair value on a nonrecurring basis to the extent that they are determined to be other-than-temporarily impaired during the period. As there is rarely an observable price or market for such investments, we determine fair value using internally developed models. Our models utilize industry valuation benchmarks, such as multiples of net revenue or EBITDA, to determine a value for the underlying enterprise. We may also reduce the value determined by the model due to illiquidity or other investee-specific characteristics which may affect the fair value. Significant decreases to these valuation benchmarks would result in significant decreases in the estimated fair values. We reduce this value by the value of debt outstanding to arrive at an estimated equity value of the enterprise. When an external event such as a purchase transaction, public offering or subsequent equity sale occurs, the pricing indicated by the external event is used to corroborate our internal valuation. Fair value measurements related to these investments are typically classified within Level 3 of the fair value hierarchy. OREO. The fair value of OREO is generally based on the lower of estimated market prices from independently prepared current appraisals or negotiated sales prices with potential buyers, less estimated costs to sell; such valuation inputs result in a fair value measurement that is categorized as a Level 2 measurement on a nonrecurring basis. As a matter of policy, appraisals are required annually and may be updated more frequently as circumstances require in the opinion of management. The Level 2 measurement for OREO is based on appraisals obtained within the last 12 months and for which a write-down was recognized during the year ended December 31, 2016. 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 147 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 13. FAIR VALUE MEASUREMENTS (Continued) input would result in a fair value measurement that is also considered a Level 3 measurement. The OREO losses disclosed are write-downs based on either a recent appraisal obtained after foreclosure or an accepted purchase offer by an independent third party received after foreclosure. Deposits. Deposits are carried at historical cost. The fair value of deposits with no stated maturity, such as noninterest-bearing demand deposits, interest checking, money market, and savings accounts, is equal to the amount payable on demand as of the balance sheet date and considered Level 2. The fair value of time deposits is based on the discounted value of contractual cash flows and considered Level 2. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. No value has been separately assigned to the Company’s long-term relationships with its deposit customers, such as a core deposit intangible. Borrowings. Borrowings include overnight FHLB advances and other fixed-rate term borrowings. Borrowings are carried at amortized cost. The fair value of overnight FHLB advances is equal to the carrying value and considered Level 1. The fair value of fixed-rate borrowings is calculated by discounting scheduled cash flows through the maturity dates or call dates, if applicable, using estimated market discount rates that reflect current rates offered for borrowings with similar remaining maturities and characteristics and are considered Level 2. Subordinated debentures. Subordinated debentures are carried at amortized cost. The fair value of subordinated debentures with variable rates is determined using a market discount rate on the expected cash flows and are considered Level 2. Derivative assets and liabilities. Derivatives are carried at fair value on a recurring basis and primarily relate to forward exchange contracts which we enter into to manage foreign exchange risk. Our derivatives are principally traded in over-the-counter markets where quoted market prices are not readily available. Instead, the fair value of derivatives is estimated using market observable inputs such as foreign exchange forward rates, interest rate yield curves, volatilities and basis spreads. We also consider counterparty credit risk in valuing our derivatives. We typically classify our foreign exchange derivatives in Level 2 of the fair value hierarchy. Equity Warrants. Equity warrants with net settlement terms are received in connection with extending loan commitments to certain of our customers. We estimate the fair value of equity warrants using a Black-Scholes option pricing model to approximate fair market value. For warrants of private companies, the model estimates market value for each warrant based on the most recent equity offering at the time of issuance, the warrant’s exercise price, the warrant’s expected life, a risk-free interest rate based on a duration-matched U.S. Treasury rate and volatility factors derived from the iShares Russell Microcap index (IWC). For warrants of publicly-traded companies, the model estimates market value for each warrant based on the share price as of the evaluation date, the warrant’s exercise price, the warrant’s expected life, a risk-free interest rate based on a duration-matched U.S. Treasury rate and uses a company-specific volatility factor. We typically classify our equity warrant derivatives in Level 3 of the fair value hierarchy. 148 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 13. FAIR VALUE MEASUREMENTS (Continued) Commitments to extend credit. The majority of our commitments to extend credit carry current market interest rates if converted to loans. Because these commitments are generally not assignable by either the borrower or us, they only have value to the borrower and us. The estimated fair value approximates the recorded deferred fee amounts and is excluded from the table above because it is not material. Limitations Fair value estimates are made at a specific point in time and are based on relevant market information and information about the financial instrument. These estimates do not reflect income taxes or any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a portion of the Company’s financial instruments, fair value estimates are based on what management believes to be conservative judgments regarding expected future cash flows, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimated fair values are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Since the fair values have been estimated as of December 31, 2016, the amounts that will actually be realized or paid at settlement or maturity of the instruments could be significantly different.

Upon a change in ownership of more than 50% of our capital stock over a three-year period as measured under Section 382 of the Internal Revenue Code (‘‘the Code’’), our ability to utilize our net operating loss forwards and other tax attributes after the ownership change generally could be limited. The annual limit would generally equal the product of the applicable long term tax exempt rate and the value of the relevant entity’s capital stock immediately before the ownership change. We acquired Square 1 on October 6, 2015. As merger consideration, we issued approximately 18.1 million shares of common stock to the Square 1 stockholders. The issuance of these shares caused us to experience an ownership change under Section 382 of the Code. Consequently, the utilization of our net operating loss carryforwards, tax credits, and other tax attributes are subject to an annual limitation. While an annual limitation on the ability to utilize tax attributes resulted from the Square 1 transaction, our ability to utilize these tax attributes over time is not expected to be any less than that prior to the Square 1 transaction. At December 31, 2016, we had no federal net operating loss carryforwards. We had available at December 31, 2016, approximately $1.1 billion of unused state net operating loss carryforwards that may be applied against future taxable income. The state net operating loss carryforwards will expire in varying amounts beginning in 2017 through 2036. As of December 31, 2016, for federal tax purposes, we had capital loss carryforwards of $31.8 million. If not used, these carryforwards will fully expire in 2018. As of December 31, 2016, for federal tax purposes, we had foreign tax credit carryforwards of $16.5 million. The foreign tax credit carryforwards are available to offset future federal taxable income. If not used, these carryforwards will begin to expire in 2017 and fully expire in 2021. 150 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 14.

The Company had net income taxes payable of $7.4 million at December 31, 2016 and net income taxes receivable of $6.2 million at December 31, 2015. 151 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 14. INCOME TAXES (Continued) As of December 31, 2016 and 2015, the Company had a valuation allowance of $100.9 million and $121.1 million against acquired DTA. Periodic reviews of the carrying amount of DTA are made to determine if a valuation allowance is necessary. A valuation allowance is required, based on available evidence, when it is more likely than not that all or a portion of a DTA will not be realized due to the inability to generate sufficient taxable income in the period and/or of the character necessary to utilize the benefit of the DTA. All available evidence, both positive and negative, that may affect the realizability of the DTA is identified and considered in determining the appropriate amount of the valuation allowance. It is more likely than not that these deferred tax assets subject to a valuation allowance will not be realized primarily due to their character and/or the expiration of the carryforward periods. The net reduction in the total valuation allowance during 2016 was $20.2 million. Of this amount, $8.7 million impacted the effective tax rate. The remaining $11.5 million principally consisted of adjustments to deferred tax assets for tax attributes that expired in 2016. These deferred tax assets had been subjected to a full valuation allowance because the Company had previously determined that they were more likely than not to not be utilized. As a result, the expiration of the tax attributes supporting the $11.5 million of deferred tax assets had no impact on the Company’s effective tax rate for the year ended December 31, 2016.

Due to the potential for the resolution of federal and state examinations and the expiration of various statutes of limitations, it is reasonably possible that our gross unrecognized tax benefits may decrease within the next twelve months by as much as $0.8 million. We recognize interest and penalties related to unrecognized tax benefits as a component of income tax expense. For the year ended December 31, 2016, we reduced our accrual for interest expense and penalties and recognized $0.6 million in income related to these items. For the year ended December 31, 2015, we reduced our accrual for interest expense and penalties and recognized $2.4 million in income related to these items. For the year ended December 31, 2014, we accrued and recognized $0.2 million in interest expense and penalties. We had $0.3 million and $0.9 million accrued for the payment of interest and penalties as of December 31, 2016 and 2015. 152 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 14.

STOCK-BASED COMPENSATION The Company’s 2003 Stock Incentive Plan as amended and restated, or the 2003 Plan, permits stock-based compensation awards to officers, directors, key employees and consultants. As of December 31, 2016, the 2003 Plan authorized grants of stock-based compensation instruments to purchase or issue up to 19,686,565 shares of Company common stock, subject to adjustments provided by the 2003 Plan. As of December 31, 2016, there were 12,314,325 shares available for grant under the 2003 Plan. Restricted Stock Restricted stock amortization totaled $22.7 million, $15.0 million and $9.8 million (excluding accelerated vesting of restricted stock of $26.1 million in 2014) for the years ended December 31, 2016, 2015 and 2014. Such amounts are included in compensation expense on the accompanying consolidated statements of earnings. The income tax benefit recognized in the consolidated statements of earnings related to this expense was $8.4 million, $5.6 million, and $3.9 million for the years ended December 31, 2016, 2015 and 2014. The amount of unrecognized compensation expense related to all unvested TRSAs and PRSUs as of December 31, 2016 totaled $45.4 million. Such expense is expected to be recognized over a weighted average period of 1.6 years.

The TRSAs generally vest over a service period of three to four years from the date of the grant or immediately upon death of an employee. For awards granted before December 11, 2014, time-based restricted common stock also vests immediately upon a change in control of the Company, as defined in the 2003 Plan. Grants issued on or after December 11, 2014, are subject to ‘‘double-trigger’’ vesting, meaning that, in the event of a change in control of the Company, as defined in the 2003 Plan, and in the event an employee’s employment is terminated by the Company without Cause or by the employee for Good Reason, as defined in the 2003 Plan, within 24 months after the change in control, such awards will vest. In April 2014, upon closing of the CapitalSource Inc. merger, 1,013,377 of awarded shares of TRSAs vested due to the triggering of the change of control provision contained within the 2003 Plan. We recorded a $26.1 million charge to earnings for the vesting of such shares. Such amount is included in acquisition, integration and reorganization costs on the accompanying consolidated statements of 154 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 16. STOCK-BASED COMPENSATION (Continued) earnings in 2014. Compensation expense related to TRSAs 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 weighted average grant date fair value per share of TRSAs granted during 2016, 2015 and 2014 were $36.05, $46.18, and $40.37. The vesting date fair value of TRSAs that vested during 2016, 2015 and 2014 were $14.4 million, $14.7 million and $53.4 million. Performance-Based Restricted Stock Units At December 31, 2016, there were 153,715 units of unvested PRSUs that have been granted. The PRSUs will vest only if performance goals with respect to certain financial metrics are met over a three-year performance period. The PRSUs are not considered issued and outstanding under the 2003 Plan until they vest. PRSUs are granted and initially expensed based on a target number. The number of awards that will ultimately vest based on actual performance will range from zero to a maximum of either 150% or 200% of target. Compensation expense related to PRSUs is based on the fair value of the underlying stock on the award date and is amortized over the vesting period using the straight-line method unless it is determined that: (1) attainment of the financial metrics is less than probable, in which case a portion of the amortization is suspended, or (2) attainment of the financial metrics is improbable, in which case a portion of the previously recognized amortization is reversed and also suspended. In the case where the performance target for the PRSU’s is based on a market condition (such as total shareholder return), the amortization is neither reversed nor suspended if it is subsequently determined that the attainment of the performance target is less than probable or improbable. If it is determined that attainment of a financial measure higher than target is probable, the amortization will increase to up to 150% or 200% of the target amortization amount. Annual PRSU expense may vary during the three-year performance period based upon changes in management’s estimate of the number of shares that will ultimately vest. The weighted average grant date fair value per share of PRSUs granted during 2016 was $27.32. There were no grants of PRSUs in 2015 and 2014. There were no PRSUs that vested during 2016, 2015 and 2014. 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 are scheduled to work a minimum of 1,000 hours and are at least 18 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) employer matching contributions was $3.7 million, $2.8 million and $1.9 million for the years ended December 31, 2016, 2015, and 2014. 155 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 18. STOCKHOLDERS’ EQUITY Common Stock Repurchased The Company’s common stock repurchased consisted of: (1) restricted stock surrendered as treasury shares and (2) stock purchased under the Company’s Stock Repurchase Program and retired. Treasury Shares 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 the years ended December 31, 2016, 2015, and 2014, the Company purchased 141,358 treasury shares at a weighted average price of $37.59 per share, 180,822 treasury shares at a weighted average price of $46.46 per share, and 493,890 treasury shares at a weighted average price of $45.16 per share. Stock Repurchase Program On October 17, 2016, PacWest’s Board of Directors authorized the Stock Repurchase Program, pursuant to which the Company may, from time to time, purchase shares of its common stock for an aggregate purchase price not to exceed $400 million. The common stock repurchases may be effected through open market purchases or in privately negotiated transactions, and may utilize any derivative or similar instrument to effect share repurchase transactions (including without limitation, accelerated share repurchase contracts, equity forward transactions, equity option transactions, equity swap transactions, cap transactions, collar transactions, floor transactions or other similar transactions or any combination of the foregoing transactions). The Stock Repurchase Program expires on December 31, 2017. The amount and exact timing of any repurchases will depend upon market conditions and other factors. The Stock Repurchase Program may be suspended or discontinued at any time. All shares repurchased under the Stock Repurchase Program were retired upon settlement. During the year ended December 31, 2016, the Company purchased 652,835 shares for $27.9 million at a weighted average price of $42.78 per share. At December 31, 2016, the remaining amount that could be used to repurchase shares under the Stock Repurchase Program was $372.1 million. Dividend Reinvestment We paid dividends on deferred shares until April 2015. The shares were deferred under a CapitalSource plan which was terminated, but due to 409A restrictions the shares remained deferred for a period of one year after termination. Dividends paid on deferred shares were used to purchase our common stock. During the year ended December 31, 2015, we paid dividends of approximately $58,000 on deferred shares, which was used to purchase an additional 1,300 shares of our common stock. During the year ended December 31, 2014, we paid approximately $115,000 on deferred shares, which was used to purchase an additional 2,583 shares of our common stock. 156 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 19. DIVIDEND AVAILABILITY AND REGULATORY MATTERS Holders of Company common stock may 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 DGCL and certain covenants contained in our subordinated debentures and borrowing agreements. Notification to the FRB is also required prior to our declaring and paying dividends during any period in which our quarterly and/or cumulative twelve-month net earnings are insufficient to fund the dividend amount, among other requirements. Should the FRB object to payment of dividends, 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 DBO, 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 California state-chartered banks such as Pacific Western are regulated by the DBO and FDIC under their general supervisory authority as it relates to a bank’s capital requirements. A state-chartered bank may declare a dividend without the approval of the DBO and FDIC 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 2016, PacWest received $259 million in dividends from the Bank. Since the Bank had an accumulated deficit of $520.0 million at December 31, 2016, for the foreseeable future, dividends from the Bank to PacWest will continue to require DBO and FDIC approval. PacWest, as a bank holding company, is subject to regulation by the FRB under the BHCA. The FDICIA 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 common equity Tier 1, Tier 1, and total capital to risk-weighted assets (‘‘total capital ratio’’), and of Tier I capital to average assets, adjusted for goodwill and other non-qualifying intangible assets and other assets (‘‘leverage ratio’’). Common equity Tier 1 capital includes common stockholders’ equity less goodwill and certain other deductions (including a portion of servicing assets and the after-tax unrealized net gains and losses on securities available-for-sale). Tier 1 capital includes common equity Tier 1 plus additional Tier 1 capital instruments meeting certain requirements. Total capital includes Tier 1 capital and other items such as subordinated debt and the allowance for credit losses. All three 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. 157 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) 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 disallowed from regulatory capital. At December 31, 2016, such disallowed amounts were $2.1 million for the Company and $0.2 million for the Bank. No assurance can be given that the regulatory capital deferred tax asset limitation will not increase in the future or that the Company or Bank will not have increased deferred tax assets that are disallowed. Banks considered to be ‘‘adequately capitalized’’ are required to maintain a minimum total capital ratio of 8.0%, a minimum Tier 1 capital ratio of 6.0%, a minimum common equity Tier 1 capital ratio of 4.5%, and a minimum leverage ratio of 4.0%. Banks considered to be ‘‘well capitalized’’ must maintain a minimum total capital ratio of 10.0%, a minimum Tier 1 capital ratio of 8.0%, a minimum common equity Tier 1 capital ratio of 6.50%, and a minimum leverage ratio of 5.0%. As of December 31, 2016, 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, 2016, that the Company and the Bank met all capital adequacy requirements to which we are subject. Basel III, the comprehensive regulatory capital rules for U.S. banking organizations, became effective for the Company and the Bank on January 1, 2015, subject to phase-in periods for certain components and other provisions. The most significant provisions of Basel III which applied to the Company and the Bank were the phase-out of trust preferred securities from Tier 1 capital, the higher risk-weighting of high volatility and past due real estate loans, and the capital treatment of deferred tax assets and liabilities above certain thresholds. Beginning January 1, 2016, Basel III requires all banking organizations to maintain a capital conservation buffer above the minimum risk-based capital requirements in order to avoid certain limitations on capital distributions, stock repurchases and discretionary bonus payments to executive officers. The capital conservation buffer is exclusively comprised of common equity tier 1 capital, and it applies to each of the three risk-based capital ratios but not to the leverage ratio. At December 31, 2016, the Company and Bank were in compliance with the capital conservation buffer requirement. The capital conservation buffer will increase by 0.625% each year through 2019, at which point, the common equity tier 1, tier 1 and total capital ratio minimums inclusive of the capital conservation buffer will be 7.0%, 8.5%, and 10.5%. 158 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 19.

The carrying value of subordinated debentures totaled $440.7 million at December 31, 2016. At December 31, 2016, none of the trust preferred securities was included in the Company’s Tier I capital under the phase-out limitations of Basel III, and $428.2 million was included in Tier II capital. Interest payments on subordinated debentures are considered dividend payments under the FRB regulations and subject to the same notification requirements for declaring and paying dividends on common stock. 159 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 20.
