15MAR201803403775 March 29, 2019 To Our Stockholders: Most notably in 2018, we successfully executed our de-risking strategy with respect to our lending portfolio and continued to return value to our stockholders. While completing our de-risking strategy, we remained focused on our operating principles of managing for profitability, controlling operating expenses, building a stable and low cost core deposit base, generating prudent and profitable loan and lease growth and proactively managing credit risk. The exceptional employees and executive management team of PacWest Bancorp (‘‘PacWest’’) and your experienced PacWest Board of Directors delivered another year of strong operating performance. Key metrics and highlights for 2018 include: (cid:129) Our net earnings increased 30% to $465.3 million, or $3.72 per diluted share, from $357.8 million, or $2.91 per diluted share for 2017; (cid:129) We achieved a return on average assets of 1.91%, a return on average tangible equity of 21.22%, and a tax equivalent net interest margin of 5.05%; (cid:129) We had loan and lease production of $4.9 billion and net loan growth of 6%; (cid:129) We grew our core deposits by $410 million; (cid:129) We improved the credit risk profile of our lending portfolio: (cid:129) classified loans and leases to total loans and leases declined to 1.32% in 2018, compared to 1.65% at last year end; (cid:129) nonaccrual loans declined to 0.44% of total loans and leases in 2018, compared to 0.92% at last year end; (cid:129) net charge-offs to average loans and leases declined to 0.26% in 2018, compared to 0.40% at last year end; and (cid:129) We closely controlled operating expenses during the year, as evidenced by an efficiency ratio of 41.0%. We began to execute our de-risking strategy in the fourth quarter of 2017 when, for both cyclical and competitive reasons, we sold approximately $1.5 billion of our cash flow loan portfolio and exited our healthcare, technology and general cash flow lending origination operations. Our remaining cash flow loans were less than 1% of total loans at year end 2018. We continued to improve the credit risk profile of our lending portfolio by emphasizing loans with favorable credit performance as follows: (cid:129) We grew our lower risk income producing residential portfolio, which are primarily multifamily loans, by 25% in 2018; (cid:129) We grew our real estate construction loans by 40% in 2018 by emphasizing loans for the construction of multifamily properties in markets with demonstrated tenant demand; (cid:129) We grew our lower risk venture capital equity fund loans by 69% in 2018. These loans grew to 39% of total venture capital loans at year end 2018 from 22% at year end 2017; and (cid:129) We continued to emphasize lower risk loans, such as premium finance and municipal lending. As a result of refocusing our lending efforts, we have significantly improved our overall credit risk profile, decreased earnings volatility and enhanced our ability to deliver stockholder value heading into 2019. In connection with the successful completion of our de-risking strategy and other long-term objectives, we will retire our CapitalSource and Square 1 Bank division names in 2019. Going forward, you will see us refer to the CapitalSource and Square 1 Bank divisions as the National Lending and Venture Banking groups, respectively, under the singular brand name of Pacific Western Bank. The Board believes operating the Bank with one brand name will contribute to our long-term objectives of growth and cohesive expansion into new markets. In 2018, we also remained steadfast in our commitment to diligent capital management and maximizing stockholder value. Our strong capital position, the success of our business strategies and our confidence in our continued ability to internally generate excess capital allowed us to continue returning capital to stockholders through a 25% increase in our quarterly cash dividend to $0.60 per common share in 2018. This increase resulted in dividends of $288 million paid to our stockholders in 2018. We also returned capital to stockholders through the continued execution of our stock repurchase program. Since inception of our stock repurchase program in October 2016 through December 31, 2018 we repurchased 8.6 million shares at an aggregate cost of approximately $434.0 million. On February 24, 2019, the Board authorized a new stock repurchase program, effective March 1, 2019, to repurchase PacWest common shares with an aggregate purchase price not to exceed $225 million. We will continue to make share repurchases as market conditions warrant through the new program maturity date of February 29, 2020. On behalf of the Board, I would like to thank our stockholders for your continued trust and confidence in PacWest and our employees and executive management team for their hard work, commitment and collaboration in helping us earn that trust and confidence every day. It is this trust and confidence in PacWest that will promote success for years to come. Sincerely, 15MAR201803383364 John M.

BUSINESS General PacWest Bancorp, a Delaware corporation, is a bank holding company registered under the BHCA with our corporate headquarters located in Beverly Hills, 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. The Bank is 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 74 full-service branches located throughout the state of California, one branch located in Durham, North Carolina, and numerous loan production offices across the country through our Community Banking, National Lending and Venture Banking groups. Community Banking provides real estate loans, commercial loans, and comprehensive deposit and treasury management services to small and medium-sized businesses conducted primarily through our California-based branch offices. National Lending provides asset-based, equipment, real estate, and security cash flow loans and treasury management services to established middle-market businesses on a national basis. Venture Banking offers loans and 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 29 acquisitions since 2000 which have contributed to our growth and expanded our market presence throughout the United States. As of December 31, 2018, we had total assets of $25.7 billion, total loans and leases, net of deferred fees, of $18.0 billion, total deposits of $18.9 billion, and stockholders’ equity of $4.8 billion. Our Business Strategy 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 principles enable us to maintain operational efficiency, increase profitability, increase 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 commercial 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. 6 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. Our management team has extensive expertise and a successful track record in evaluating, executing and integrating attractive, franchise-enhancing acquisitions. We have successfully completed 29 acquisitions since 2000, including the CUB acquisition on October 20, 2017. 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, mobile, remote deposit, and telephone banking platforms, all of 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, 2018, we had ATMs at 59 of our branches 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. At December 31, 2018, our total deposits consisted of $16.3 billion in core deposits, $2.0 billion in time deposits and $0.5 billion in non-core non-maturity deposits. Core deposits represented 87% of total deposits at December 31, 2018, and were comprised of $7.9 billion in noninterest-bearing deposits, $2.8 billion in interest-bearing checking accounts, $5.0 billion in money market accounts and $0.6 billion in savings accounts. Our deposit base is also diversified by client type. As of December 31, 2018, no individual depositor represented more than 1.0% of our total deposits, and our top ten depositors represented 7.5% of our total deposits. We face strong competition in gathering deposits from nationwide, regional, and community banks, credit unions, 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 7 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, 2018, total off-balance sheet client investment funds were $1.9 billion, of which $1.5 billion was managed by S1AM. Lending Activities Our lending activities include real estate mortgage loans, real estate construction and land loans, commercial loans and leases, and a small amount of consumer loans. Our commercial real estate loans and real estate construction loans are secured by a variety of property types. Our commercial loans and leases are diverse and generally include various asset-secured loans, equipment-secured loans and leases, venture capital loans to support venture capital firms’ operations and the operations of entrepreneurial companies during the various phases of their life cycles, secured business loans originated through our Community Banking group, and loans to security alarm monitoring companies. Until December 2017, we actively originated cash flow loans used to finance business acquisitions and recapitalizations to various types of borrowers, with greater emphasis on borrowers operating in the healthcare and technology industries. In December 2017, we exited most cash flow lending business lines, and we agreed to sell $1.5 billion of cash flow loans (of which $481.1 million were held for sale at December 31, 2017 and were subsequently sold in the first quarter of 2018). At December 31, 2018, we held $92.5 million of cash flow loans from the lending businesses that we exited. 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 third-party lenders. We also have an additional exposure to consumer loans as many of our lender finance and timeshare loans are secured by the receivables owed to our borrowers by individual consumers. Some of our loans are participations in larger loans, and these participations may be considered a SNC. A SNC is any loan or commitment to extend credit aggregating $100 million or more at origination ($20 million or more prior to January 1, 2018), committed under a formal lending arrangement, and shared by three or more unaffiliated supervised institutions. The SNC program is governed by an inter-agency agreement among the FRB, the FDIC, and the OCC. 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. At December 31, 2018 and 2017, we had SNC loans held for investment to 30 borrowers that totaled $840 million and to 55 borrowers that totaled $1.2 billion. Real Estate Mortgage Loans and Real Estate Construction and Land Loans Our real estate lending activities focus primarily on loans to professional developers and real estate investors for the acquisition, construction, refinancing, renovation, and on-going operation of commercial real estate. We also provide commercial real estate loans to borrowers operating businesses at these sites (owner occupied commercial real estate loans), including loans to municipalities, schools and school districts, and non-profit borrowers as part of our tax-exempt lending business line. 8 Our real estate secured loans include the following specific lending products: (cid:129) Commercial real estate mortgage. Our commercial real estate mortgage loans generally are collateralized by first deeds of trust on specific commercial properties. The most prevalent types of properties securing our commercial real estate loans are office properties, hotels, retail properties, industrial properties, and various healthcare properties such as skilled nursing facilities and assisted living facilities. The properties are typically located in central business districts across the United States with a significant concentration of collateral properties located in California within our branch footprint. Our commercial real estate loans typically either 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 or may have an initial interest-only period followed by an amortization schedule with a lump sum balloon payment due in one to ten years. We also provide commercial 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 504 mortgage loans repay on a twenty-five year amortization schedule. (cid:129) Income producing and other residential real estate mortgage. Our income producing and other residential real estate mortgage loans generally are collateralized by first deeds of trust on specific multi-family and other residential properties. The most prevalent types of properties securing our income producing and other residential real estate loans are multi-family, condominium, pooled single-family rental properties, and individual single-family properties. We also purchase multi-family secured real estate mortgage loans from other banks due primarily to the favorable credit risk profile of multi-family loans. When we purchase multi-family loans from other banks, we re-underwrite the loans at time of purchase. Multi-family loans typically repay on a 30-year amortization schedule. We do not typically originate single-family mortgage loans, although we do purchase this type of loan from a third-party lender. (cid:129) Real estate construction and land. Our real estate construction and land loans generally are collateralized by first deeds of trust on specific residential and commercial properties. The most prevalent types of properties securing our construction and land loans are multi-family, condominium, and hotel properties. Construction loans typically finance from 50% to 70% of the costs to construct residential and commercial properties. The terms are generally one to three years with short-term, performance-based extension options. We do not currently originate single-family construction loans, although we do purchase this type of loan from a third-party lender. 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. 9 In addition to the points above, real estate 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 or timelines; (cid:129) disagreement between contractors, subcontractors and developers; (cid:129) demand for completed projects being less than anticipated; and (cid:129) buyers of the completed projects not being able to secure permanent financing. Real estate mortgage loans include loans secured by healthcare properties, primarily skilled nursing facilities. In addition to the points above, 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. 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) requiring borrowers to invest and maintain a meaningful cash equity interest in the properties securing our loans; (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 acceptance standards, including among other factors, maximum loan to acquisition or construction cost ratios, maximum loan to as-is or stabilized value ratios, and minimum operating cash flow requirements; (cid:129) considering market rental rates relative to our underwritten or projected rental rates; (cid:129) considering the experience of our borrowers and our borrowers’ abilities to operate and manage the properties securing our loans; (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 real estate construction loans, in addition to the foregoing, we attempt to mitigate project-specific risks by: (cid:129) considering the experience of our borrowers and our borrowers’ abilities to manage the properties during construction and into the stabilization periods; (cid:129) obtaining project completion guaranties from our borrowers; 10 (cid:129) including covenants in our construction loan agreements that require the borrowers to fund costs that exceed the initial construction budgets; (cid:129) implementing a controlled disbursement process for loan proceeds in accordance with an agreed upon schedule, which usually results in the borrowers’ equity being invested before loan advances commence and which ensures the costs to complete the projects are in balance with our remaining unfunded loan commitments; (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. Commercial Loans and Leases Our commercial loans and leases are diverse and generally include various asset-secured loans, equipment-secured loans and leases, venture capital loans to support venture capital firms’ operations and the operations of entrepreneurial companies during the various phases of their life cycles, secured business loans originated through our Community Banking group, and loans to security alarm monitoring companies. Our commercial loans and leases include the following specific lending products: (cid:129) Lender finance & timeshare. These are loans to companies 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 borrowers include commercial lenders, consumer lenders, and timeshare operators. The primary sources of repayment are the operating incomes of the borrowers and the collection of the finance receivables securing the loans. The loans are typically revolving lines of credit with terms of one to three years with contractual borrowing availability as a percentage of eligible collateral. (cid:129) Equipment finance. These are loans and leases 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. (cid:129) Other asset-based. These are loans used for working capital and are secured by trade accounts receivable and/or inventories. The primary sources of repayment are the operating incomes of the borrowers, the collection of the receivables securing the loans, and/or the sale of the inventories securing the loans. The loans are typically revolving lines of credit with terms of one to three years with contractual borrowing availability as a percentage of eligible collateral. 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. 11 (cid:129) Premium finance. These 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. The primary sources of repayment are the cash flow of the borrowers and guarantors, repayment from our loans being refinanced by other lenders, or the application of cash surrender value proceeds to the loans. (cid:129) Venture capital. These are loans to venture-backed companies or loans directly to venture capital firms. Loans to venture-backed companies support the borrowers’ operations, including operating losses, working capital requirements, and fixed asset acquisitions. The borrowers are at various stages in their development (early, expansion, or late), 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. The loan terms are generally one to four years, and the loans are typically secured by a first priority, secured blanket lien on all corporate assets and/or a lien on intellectual property. This loan segment also includes equity fund loans which are loans made 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, proceeds from sales of portfolio company investments, and management fees. The loan terms are generally one to four years, and the loans are typically secured by a first position lien on the assets of the business, an assignment of capital call rights and/or an assignment of management fees. (cid:129) Secured business. These are secured business loans originated through the Community Banking group. The primary source of repayment is the cash flow of the borrowers. The loans can be up to five years and are secured by a specific asset or assets of the borrower. (cid:129) Security monitoring. These are loans to security monitoring companies used to support the operations of companies that provide business and residential security systems and the accompanying alarm monitoring services. Loans to security monitoring companies are secured primarily by the monitoring contracts between the borrowers and their customers. The primary sources of repayment are the operating incomes of the borrowers, proceeds from the sales of security monitoring contracts to other monitoring companies, and proceeds from the sale of the borrowers themselves. The loans are typically revolving lines of credit with terms of one to three years with contractual borrowing availability as a ratio of the total recurring monthly billing amount from eligible monitoring contracts (collateral). Loans to security monitoring borrowers are usually considered leveraged loans. According to regulatory guidance, 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 annual adjusted earnings of the borrower. (cid:129) Other lending. Loans aggregated into the category of ‘‘Other lending’’ are various commercial loan types including Community Banking group business loans secured by a blanket lien on the borrowers’ businesses, loans to homeowner associations, loans to municipalities and non-profit borrowers, and SBA 7(a) loans for small business expansion. The primary sources of repayments for the Community Banking group business loans, non-profit borrowers, and SBA 7(a) business expansion loans are the operations of the borrowers. The primary sources of repayment for loans to municipalities are tax collections from their tax jurisdictions. (cid:129) Cash flow. Until December 2017, we actively originated cash flow loans to finance business acquisitions and recapitalizations to various types of borrowers, with greater emphasis on borrowers operating in the healthcare and technology industries. In December 2017, we exited most cash flow lending business lines, and agreed to sell $1.5 billion of cash flow loans (of which $481.1 million were held for sale at December 31, 2017 and were subsequently sold in the first 12 quarter of 2018). At December 31, 2018, we held $114.1 million of cash flow loans, including $92.5 million from the lending businesses that we exited in December 2017. Our portfolio of commercial 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; (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 commercial loans and leases, we seek to mitigate risk by using the following framework: (cid:129) considering the prospects for the borrower’s industry and competition; (cid:129) considering our past experience with the borrower and with the collateral type; (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. We actively manage real estate and commercial loans and seek to mitigate credit risk on most loans by using the following framework. (cid:129) monitoring the economic conditions in the regions or areas in which our borrowers are operating; (cid:129) measuring operating performance of our borrower or collateral and comparing it to our underwriting expectations; (cid:129) assessing compliance with financial and operating covenants as set forth in our loan agreements and considering the effects of incidences of noncompliance and taking corrective actions; (cid:129) assigning a credit risk rating to each loan and ensuring the accuracy of our credit risk ratings by using an independent credit review function to assess the appropriateness of the credit risk ratings assigned to loans; (cid:129) conducting loan portfolio review meetings where senior management and members of credit administration discuss the credit status and related action plans on loans with unfavorable credit risk ratings; and (cid:129) subjecting loan modifications and loan renewal requests to underwriting and assessment standards similar to the underwriting and assessment standards applied before closing the loans. 13 Consumer Loans Consumer loans are primarily purchased private student loans originated and serviced by third- parties 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. Consumer loans may also include personal loans, auto loans, home equity lines of credit, revolving lines of credit, and other loans typically made by banks to individual borrowers. 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-servicers of the Bank’s student loans to service the loans in accordance with the terms of the loan purchase agreements. 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. 14 Loan Concentrations The following table presents the composition of our loans and leases held for investment, net of deferred fees, by loan portfolio segment and class as of the dates indicated: Real estate mortgage: Commercial . . . . . . . . . . . . . . . . . . . .

At December 31, 2017 and 2016, the balances of these loans totaled $249.3 million and $2.3 billion. Such cash flow loans are included in the ‘‘Other commercial’’ loan portfolio class in the table. Our loan portfolio segments of real estate mortgage loans, real estate construction and land loans, and commercial loans comprised 44%, 13%, and 41% of our total loans and leases held for investment at December 31, 2018, respectively, compared to 46%, 10%, and 42% at December 31, 2017, respectively. Real estate mortgage loans are diversified among various property types. At December 31, 2018, the three largest property types securing real estate mortgage loans were multi-family properties, office properties, and industrial properties, which comprised 36%, 16%, and 13%, of our real estate mortgage loans, respectively. At December 31, 2017, the three largest property types securing real estate mortgage loans were multi-family properties, industrial properties, and office properties, which comprised 27%, 15% and 14%, of our real estate mortgage loans, respectively. At December 31, 2018 and 2017, 13% and 14% of the total real estate mortgage loans were owner occupied (where our borrowers were operating businesses on the premises that collateralize our loans). 15 Real estate construction and land loans are diversified among various property types. At December 31, 2018, the three largest property types for real estate construction and land loans were multi-family properties, hotel properties, and residential condominium properties, which comprised 32%, 14%, and 13% of our real estate construction and land loans, respectively. At December 31, 2017, the three largest property types for real estate construction and land loans were multi-family properties, residential condominium properties, and office properties, which comprised 27%, 10%, and 10% of our real estate construction and land loans, respectively. At December 31, 2018, commitments secured by real estate construction projects totaled $4.9 billion with related outstanding loan balances of $2.2 billion. At December 31, 2017, commitments secured by real estate construction projects totaled $3.6 billion with related outstanding loan balances of $1.6 billion. At December 31, 2018, commitments related to construction projects in California totaled $2.8 billion or 57% of total real estate construction commitments, and commitments related to construction projects in New York City totaled $688.4 million or 14% of total real estate construction commitments. At December 31, 2018, there were eight individual real estate construction commitments greater than or equal to $100 million with the largest two commitments both being $150.0 million. At December 31, 2018, these eight individual commitments totaled $940.8 million and had outstanding balances that totaled $259.2 million. The projects financed by these commitments were a hotel, office building, five multi-family projects, and a residential condominium complex. For these specific commitments, the average commitment to budgeted projected cost ratio was 51.4%. At December 31, 2018, our largest individual loan commitment was $155.0 million and we had six individual loan commitments each of $150.0 million. These commitments were for equity fund loans, lender finance loans, and commercial construction loans. At December 31, 2018, our ten largest individual loan commitments totaled $1.5 billion and had corresponding outstanding balances that totaled $732.7 million. These ten largest commitments ranged from $130.0 million to $155.0 million. These commitments were for equity fund loans, lender finance loans, commercial construction loans, other commercial real estate loans, and secured business loans. At December 31, 2017, our ten largest individual loan commitments totaled $908.9 million and had corresponding outstanding balances that totaled $516.2 million. These ten largest commitments ranged from $75.0 million to $110.0 million. These commitments were for residential construction loans, lender finance loans, commercial construction loans, other commercial real estate loans, hospitality loans, and income producing residential loans. Current Developments Colorado Market Expansion During the fourth quarter of 2018, we established executive offices and expanded our loan production capabilities to include Community Banking in the Denver, Colorado area. In January 2019, we hired a Colorado Market President to lead this effort. In February 2019, we applied for a license in Colorado to accept deposits and plan to open a full-service branch in Denver. We intend to follow our existing Community Banking group model of making business and real estate loans to local borrowers funded by low-cost, locally-obtained deposits. 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, 2018 of $3.7 billion, collateralized by a blanket lien on $5.4 billion of qualifying loans. The Bank also had 16 secured financing capacity with the FRBSF of $2.0 billion as of December 31, 2018 collateralized by liens on $2.7 billion of qualifying loans. Information Technology Systems We devote significant financial and management 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, mobile, and telephone banking services to further improve the overall client experience. In 2018, we completed the migration of in-house and outsourced systems for managing customer accounts to an alternative platform to enhance the features and services available to our customers. We use an enterprise data warehouse system in order to aggregate, 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 an information technology strategic plan. This 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, detect unusual activity, 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 minimize potential risk to operations, and reduce the risk that cyber-attacks would be successful. To protect our business operations against disasters, we have a backup off-site 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. 17 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 than what we are willing 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 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, 2019, we had 1,833 full time equivalent employees. None of the Company’s employees are represented by collective bargaining agreements. 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.’’ 18 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 other 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. The current U.S. political environment adds 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. 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. 19 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 20. 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. In May 2018, the Economic Growth, Regulatory Relief, and Consumer Protection Act (‘‘EGRRCPA’’) was enacted. While the EGRRCPA reduced the impact of the Dodd-Frank Act on bank holding companies of our size, including in respect to stress testing, the Dodd-Frank Act nonetheless subjected us to additional significant regulatory requirements. In addition, as a result of the Dodd-Frank Act and our having in excess of $10 billion in total consolidated assets, the Company and the Bank are 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 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 20 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 addition, prior approval of the FRB is required prior to our repurchasing shares of our common stock. In connection with the decision regarding dividends and share repurchase programs, our Board 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. 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 the Bank. Dividends paid by the Bank are regulated by the DBO and FDIC under their general supervisory authority as it relates to a bank’s capital requirements. The 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. Dividends paid by the Bank during the previous three fiscal years exceeded the Bank’s earnings during that same period by $28.5 million. Since the Bank had a retained deficit of $643.9 million at December 31, 2018, 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 20. 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. 21 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 and the institution’s ‘‘eligible retained income’’ (that is, four quarter trailing net income, net of distributions and tax effects not reflected in net income). As of January 1, 2019, the capital conservation buffer is fully phased-in and the Company and the Bank are required to maintain an additional capital conservation buffer of 2.5% of CET1, effectively resulting in minimum 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 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 was phased-in beginning at 40% in 2015, 60% in 2016, and 80% for 2017 and 2018. 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. 22 The Company has outstanding subordinated debentures issued to trusts, which, in turn, issued trust preferred securities. The carrying amount of subordinated debentures totaled $453.8 million at December 31, 2018. Under Basel III, none of the Company’s trust preferred securities are included in Tier 1 capital, however $440.2 million of such trust preferred securities was included in Tier 2 capital at December 31, 2018. We believe that, as of December 31, 2018, 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, 2018 for the Company and the Bank. Stress Testing Though the Company and Bank are no longer required to prepare annual stress tests pursuant to the Dodd-Frank Act, we continue to prepare an annual stress test of our capital, consolidated earnings and losses under adverse economic and market conditions. 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. 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. The agencies have adopted regulations and interagency guidelines which set forth the safety and soundness standards used to identify and address problems at insured depository institutions before capital becomes impaired. If an agency determines that a bank fails to satisfy any standard, it may require the bank to submit an acceptable plan to achieve compliance, consistent with deadlines for the submission and review of such safety and soundness compliance plans. If an institution fails to submit an acceptable compliance plan or fails in any material respect to implement an acceptable compliance plan, the agency must issue an order directing action to correct the deficiency and may issue an order directing other actions of the types to which an undercapitalized institution is subject under the FDIA. Deposit Insurance The Bank is a state-chartered, ‘‘non-member’’ bank regulated by the DBO and the FDIC. The Bank 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. During the first quarter of 2016, the FDIC issued a final rule implementing a 4.5 basis points surcharge on the quarterly FDIC insurance assessments of insured depository institutions with more than $10 billion in total consolidated assets. The Bank became subject to the FDIC surcharge on July 1, 2016. The surcharge continued through September 30, 2018, when the Deposit Insurance Fund reserve ratio reached 1.36% of insured deposits, exceeding the statutorily required minimum reserve 23 ratio of 1.35%. For the year ended December 31, 2018, we incurred $15.9 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 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. In August 2015, the SEC adopted final rules implementing the pay ratio provisions of the Dodd-Frank Act by requiring companies to disclose the ratio of the compensation of its chief executive officer to the median compensation of its employees. Under SEC guidance issued in September 2017, companies such as the Company are able to use widely-recognized tests to determine who counts as an employee under the rule, use existing internal records such as payroll and tax information and describe the ratio as an estimate. For a registrant with a fiscal year ending on December 31, such as the Company, the pay ratio was first required as part of its executive compensation disclosure in proxy statements or Form 10-Ks filed in 2018. 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, 24 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. 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. The U.S. Department of the Treasury’s Financial Crimes Enforcement Network (‘‘FinCEN’’) drafts regulations implementing the PATRIOT ACT and other anti-money laundering and Bank Secrecy Act legislation. In May 2017, a FinCEN rule became effective which requires financial institutions to obtain beneficial ownership information with respect to legal entities with which such institutions conduct business, subject to certain exclusions and exemptions. 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. 25 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 (‘‘CRA’’) 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 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 ‘‘Outstanding’’ 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. In April 2018, the U.S. Department of Treasury issued a memorandum to the federal banking regulators recommending changes to the CRA’s regulations to reduce their complexity and associated burden on banks. We will continue to evaluate the impact of any changes to the CRA regulations. Customer Information Privacy and Cybersecurity 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. 26 In March 2015, federal regulators issued two related statements regarding cybersecurity. One statement indicates that financial institutions should design multiple layers of security controls to establish lines of defense and to ensure that their risk management processes also address the risk posed by compromised customer credentials, including security measures to reliably authenticate customers accessing Internet-based services of the financial institution. The other statement indicates that a financial institution’s management is expected to maintain sufficient business continuity planning processes to ensure the rapid recovery, resumption and maintenance of the institution’s operations after a cyber-attack involving destructive malware. A financial institution is also expected to develop appropriate processes to enable recovery of data and business operations and address rebuilding network capabilities and restoring data if the institution or its critical service providers fall victim to this type of cyber-attack. If we fail to observe the regulatory guidance, we could be subject to various regulatory sanctions, including financial penalties. The Gramm-Leach-Bliley Act of 1999 (the ‘‘GLBA’’) requires financial institutions to implement policies and procedures regarding the disclosure of non-public personal information about consumers to non-affiliated third parties. The GLBA requires 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 that are distributed regularly to all existing and new customers of the Bank. State regulators have been increasingly active in implementing privacy and cybersecurity standards and regulations. Recently, several states have adopted regulations requiring certain financial institutions to implement cybersecurity programs and providing detailed requirements with respect to these programs, including data encryption requirements. Many states have also recently implemented or modified their data breach notification and data privacy requirements. In June 2018, the California legislature passed the California Consumer Privacy Act of 2018 (the ‘‘California Privacy Act’’), which is scheduled to take effect on January 1, 2020. The California Privacy Act, which covers businesses that obtain or access personal information on California resident consumers, grants consumers enhanced privacy rights and control over their personal information and imposes significant requirements on covered companies with respect to consumer data privacy rights. We expect this trend of state-level activity to continue, and are continually monitoring developments in the states in which we operate. For a further discussion of risks related to privacy and cybersecurity, see ‘‘Item 1A. Risk Factors’’ included in this Form 10-K. Regulation of Certain Subsidiaries 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. 27 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 nine-year expansion since the Great Recession ended in 2009. This current expansion has been longer than most U.S. expansionary periods in recent history. In the event of an economic recession, our operating results could be adversely affected because we could 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. Brexit, including the possibility of Brexit without an agreement between the United Kingdom and the European Union, has the potential to impact global economic conditions which may in turn impact U.S. economic conditions, but we would not expect any direct impact as we do not operate in the United Kingdom. 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 often signal broader economic deterioration and/or a downward trend in business earnings which may adversely affect businesses’ ability to raise capital and/or 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; or (cid:129) an increase in our operating expenses associated with attending to the effects of certain circumstances listed above. 28 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 to assist in executing our growth, acquisition, and business strategies. 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 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, 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 the collection of loan and lease principal, interest, and fees 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. Some of our loans and leases are secured by a lien on specified collateral of the borrower 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. Additionally, loans to venture-backed companies support the borrowers’ operations, including operating losses, working capital requirements and fixed asset acquisitions. Venture-backed 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. Our venture-backed borrowers’ business plans may fail, increasing the likelihood for credit losses related to loans to venture-backed companies. 29 At December 31, 2018, loans to venture-backed companies totaled $1.2 billion or 7% of total loans and leases. For the year ended December 31, 2018, net charge-offs related to venture-backed borrowers totaled $24.2 million or 55% of total net charge-offs for this period. In accordance with U.S. GAAP, we maintain an allowance for loan and lease losses to provide for loan defaults and non-performance. Our allowance for loan and lease losses allocable to loans to venture-backed borrowers may not be adequate to absorb actual credit losses arising from these loans, and future provisions for credit losses could materially and adversely affect our operating results. Our allowance for credit losses may not be adequate to cover actual losses. In accordance with U.S. GAAP, 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 influenced by 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 loans and leases are concentrated by location, collateral value, and borrower type which could exacerbate credit losses if certain markets or industries were to experience economic difficulties or operating issues. Real estate mortgage loans and real estate construction and land loans comprised 57% of our total loans and leases at December 31, 2018. Of total loans and leases, 32% are secured by real estate collateral located in California, 20% are secured by multi-family properties, and 5% are secured by commercial real estate construction projects. For real estate mortgage 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 refinancing of the properties. For real estate construction and land loans, the primary source of loan repayments is the proceeds from the sales or refinancing of the properties following the completion of construction and the stabilization/attainment of sufficient debt service coverage. 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. We have a number of large credit relationships and individual commitments. At December 31, 2018, we had 28 credit relationships with aggregate commitments greater than $100 million. These 28 relationships had commitments that totaled $4.8 billion and corresponding outstanding balances of $2.8 billion. These relationships include loans to borrowers where a common enterprise has been determined to exist. Examples of a common enterprise are control through majority ownership, common management, or the sharing of a material guarantor. The aggregated loans typically are not cross collateralized and each borrower’s performance does not usually affect the collectability of the other loans in the aggregation. 30 At December 31, 2018, our largest individual loan commitment was $155.0 million and we had six individual loan commitments each of $150.0 million. These commitments were for equity fund loans, lender finance loans, and commercial construction loans. At December 31, 2018, our ten largest individual loan commitments totaled $1.5 billion and had corresponding outstanding balances that totaled $732.7 million. These ten largest commitments ranged from $130.0 million to $155.0 million. These commitments were for equity fund loans, lender finance loans, commercial construction loans, other commercial real estate loans, and secured business loans. At December 31, 2017, our ten largest individual loan commitments totaled $908.9 million and had corresponding outstanding balances that totaled $516.2 million. These ten largest commitments ranged from $75.0 million to $110.0 million. These commitments were for residential construction, lender finance loans, commercial construction loans, other commercial real estate, hospitality loans, and income producing residential loans. We are potentially vulnerable to significant loan losses in the event that the value of one of our larger borrower’s collateral rapidly declines or one of our larger borrowers becomes unable to repay its loans due to a decline in its business. A significant loss related to one of our large lending relationships or individual commitments could have a material adverse effect on our financial condition and results of operations. A slowdown in venture capital investment levels may reduce the market for venture capital investment for our Venture Banking clients, which could adversely affect our business, results of operations, or financial condition. Our Venture Banking group’s strategy is focused on providing banking products and credit 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 significant portion of deposits, including large 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 clients will receive additional rounds of equity capital from investors. If the amount of capital available to such companies decreases, 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. 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. 31 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 contractual interest and principal due to us. 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 loans that mature and repay or that prepay before maturity with new originations, minimize increases on our deposit rates, and maintain an acceptable level and composition 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 interest 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, average loan portfolio balance, liquidity, and overall profitability. 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 or any given market segment or industry in which we are invested. 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 principal and interest payments sufficient to recover our amortized cost of 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. 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. 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 international credit markets. 32 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 we pay dividends, among other things, 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. The 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 the three previous fiscal years less any dividend paid during such period. Dividends paid by the Bank during the previous three fiscal years exceeded the Bank’s net earnings during that same period by $28.5 million. Since the Bank had an accumulated deficit of $643.9 million at December 31, 2018, 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. We may reduce or discontinue the payment of dividends on common stock. Our stockholders are only entitled to receive such dividends as our Board 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. 33 Capital Risk 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 may be restricted in the types of activities we may conduct and may be prohibited from taking certain capital actions, such as making TruPS payments or paying executive bonuses or dividends, and repurchasing or redeeming capital securities. We may need to raise additional capital in the future and such capital may not be available when needed or at all. We are required by federal and state regulators to maintain adequate levels of capital. We may need to raise additional capital in the future to meet regulatory or other internal requirements. 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. We cannot provide any assurance that access to such capital 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 counter-parties 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. The 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. 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, any failure to 34 comply with any applicable laws or regulations, or regulatory policies and interpretations of such laws and regulations, could result in regulatory enforcement actions, 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 are undergoing continuous review and frequent change. 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, or (iv) otherwise materially and adversely affect our business or prospects for business. While new legislation in 2018 scaled back portions of the Dodd-Frank Act and the current administration in the United States may ultimately roll back or modify certain of the regulations adopted since the financial crisis, future changes in bank regulation are uncertain and could negatively impact our business. Though the Company and Bank are no longer required to prepare annual stress tests pursuant to the Dodd-Frank Act, we continue to prepare an annual stress test of our capital, consolidated earnings and losses under adverse economic and market conditions. 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. 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 or new interpretations of existing tax laws could occur. 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, state, and local 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 subsidiaries and certain of our and their directors and officers 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 U.S. GAAP 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. 35 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. Many of our competitors have significantly greater resources, established customer bases, more locations, and longer operating histories. 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. Defense of our reputation, trademarks, and other intellectual property, including through litigation, also could result in costs that could have a material adverse effect on our business, financial condition, or results of operations. Our acquisitions may subject us to unknown risks. Risks Related to Risk Management As an active acquirer having successfully completed 29 acquisitions since 2000, 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 36 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 our strategic initiatives successfully will depend on a variety of factors. These factors likely will vary based on the nature of the initiative 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. To the extent we issue capital stock in connection with future acquisitions, these transactions may be dilutive to tangible book value and will dilute share ownership. Failure to keep pace with technological change could adversely affect our business. 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 conversion to a new core processing system related to managing customer accounts during 2018. 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 implement core processing strategies could have a material adverse impact on our business and, in turn, our financial condition and results of operations. A failure, interruption or breach in the security of our systems, or those of contracted vendors, 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. 37 Many financial institutions, including the Company, 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, cyber-attacks and other means. We have been targeted by individuals and groups using phishing campaigns, pretext calling, 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 cyber-attacks 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, including those of our third-party vendors, 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, increased insurance premiums, 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, telecommunications, 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. 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 or significant deficiencies in our internal control over financial reporting or are required to restate our financial statements, we could be 38 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 or significant deficiencies 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 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 and Other Estimates The Company’s consolidated financial statements are based in part on assumptions and estimates which, if incorrect, could cause unexpected losses in the future. We have made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the 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 these estimates. Material estimates subject to change in the near term include, among other items, the allowance for credit losses, the carrying value of intangible assets, the fair value estimates of certain assets and liabilities, and the realization of deferred tax assets and liabilities. These estimates may be adjusted as more current information becomes available, and any adjustment may be significant. There are risks resulting from the extensive use of models in our business. We rely on quantitative models to measure risks and to estimate certain financial values. Models may be used in such processes as determining the pricing of various products, grading loans and extending credit, measuring interest rate and other market risks, predicting or estimating losses, assessing capital adequacy and calculating regulatory capital levels, as well as to estimate the value of financial instruments and balance sheet items. Poorly designed or implemented models present the risk that our business decisions based on information incorporating model output could be adversely affected due to the inaccuracy of that information. Some of the decisions that our regulators make, including those related to capital distributions, could be affected due to the perception that the quality of the models used to generate the relevant information is insufficient, which could have a negative impact on our ability to make capital distributions in the form of dividends or share repurchases. 39 ITEM 1B.

This comparison assumes $100 was invested on December 31, 2013, 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 loss was 2.31% over the five year period ending December 31, 2018 compared to gains of 65.84% and 42.33% 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, a Delaware corporation, is a bank holding company registered under the BHCA, with our corporate headquarters located in Beverly Hills, 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. The Bank is 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 74 full-service branches located throughout the state of California, one branch located in Durham, North Carolina, and numerous loan production offices across the country through our Community Banking, National Lending and Venture Banking groups. Community Banking provides real estate loans, commercial loans, and comprehensive deposit and treasury management services to small and medium-sized businesses conducted primarily through our California-based branch offices. National Lending provides asset-based, equipment, real estate, and security cash flow loans and treasury management services to established middle-market businesses on a national basis. Venture Banking 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, 2018, we had total assets of $25.7 billion, including $18.0 billion of total loans and leases, net of deferred fees, and $4.0 billion of securities available-for-sale, compared to $25.0 billion of total assets, including $17.5 billion of loans and leases, net of deferred fees, and $3.8 billion of securities available-for-sale at December 31, 2017. The $736.5 million increase in total assets during 2018 was due primarily to a $503.9 million increase in loans and leases and a $235.0 million increase in securities available-for-sale. The increase in loans and leases was driven mostly by production of $4.9 billion and disbursements of $4.1 billion, offset partially by payoffs and paydowns of $7.8 billion and sales of $641.9 million, including settlement of the loans held for sale at December 31, 2017. The increase in securities available-for-sale was due mainly to purchases exceeding sales, principal paydowns, maturities, and other reductions. At December 31, 2018, we had total liabilities of $20.9 billion, including total deposits of $18.9 billion and borrowings of $1.4 billion compared to $20.0 billion of total liabilities, including total deposits of $18.9 billion and borrowings of $467.3 million at December 31, 2017. The $888.5 million increase in total liabilities during 2018 was due mainly to a $903.8 million increase in borrowings, primarily short-term FHLB advances, and a $409.7 million increase in core deposits, offset partially by a $345.0 million decrease in non-core non-maturity deposits and a $59.7 million decrease in time deposits. At December 31, 2018, core deposits totaled $16.3 billion, or 87% of total deposits, including $7.9 billion of noninterest-bearing demand deposits, or 42% of total deposits. At December 31, 2018, we had total stockholders’ equity of $4.8 billion compared to $5.0 billion at December 31, 2017. The $152.0 million decrease in stockholders’ equity during 2018 was due mainly to $306.4 million of common stock repurchased under the Stock Repurchase Program, $288.2 million of cash dividends paid, and a $37.2 million decline in accumulated other comprehensive income, offset partially by $465.3 million in net earnings. Consolidated capital ratios remained strong with Tier 1 capital and total capital ratios of 10.01% and 12.72% at December 31, 2018. 46 Recent Events Stock Repurchase Program Our Stock Repurchase Program was initially authorized by PacWest’s Board of Directors on October 17, 2016, pursuant to which the Company could, until December 31, 2017, purchase shares of its common stock for an aggregate purchase price not to exceed $400 million. On November 15, 2017, PacWest’s Board of Directors amended the Stock Repurchase Program to reduce the authorized purchase amount to $150 million and extend the maturity date to December 31, 2018. On February 14, 2018, PacWest’s Board of Directors amended the Stock Repurchase Program to increase the authorized purchase amount to $350 million and extend the maturity date to February 28, 2019. On February 24, 2019, effective upon the maturity of the current Stock Repurchase Program on February 28, 2019, PacWest’s Board of Directors authorized a new Stock Repurchase Program to purchase shares of its common stock for an aggregate purchase price not to exceed $225 million until February 29, 2020. 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. During the fourth quarter of 2016, the Company repurchased 652,835 shares of common stock for a total amount of $27.9 million. During 2017, the Company repurchased 2,081,227 shares of common stock for a total amount of $99.7 million. During 2018, the Company repurchased 5,849,234 shares of common stock for a total amount of $306.4 million. All shares repurchased under the Stock Repurchase Program were retired upon settlement. At December 31, 2018, the remaining amount that could be used to repurchase shares under the Stock Repurchase Program was $110.1 million. After the authorization of a new Stock Repurchase Program on February 24, 2019, the amount that could be used to repurchase shares will be $225 million as of March 1, 2019. CU Bancorp Acquisition PacWest acquired CUB on October 20, 2017 in a transaction valued at $670.6 million. As part of the acquisition, CU Bank, a wholly-owned subsidiary of CUB, was merged with and into the Bank. CU Bank was a commercial bank headquartered in Los Angeles, California with nine branches located in Los Angeles, Orange, Ventura, and San Bernardino counties. We completed the acquisition to, among other things, enhance our Southern California community bank franchise by adding a $2.1 billion loan portfolio and $2.7 billion of core deposits. We recorded the acquired assets and liabilities, both tangible and intangible, at their estimated fair values as of the acquisition date and increased total assets by $3.5 billion. The application of the acquisition method of accounting resulted in goodwill of $374.7 million. For further information, see Note 3. Acquisitions of the Notes to Consolidated Financial Statements contained in ‘‘Item 8. Financial Statements and Supplementary Data.’’ Loan Sales and Loans Held for Sale In the fourth quarter of 2017, we entered into an agreement to sell $1.5 billion of cash flow loans (the ‘‘Cash Flow Loan Sale’’). Of the $1.5 billion in loans sold, none were on nonaccrual and $4.7 million were classified, and we also exited our National Lending origination operations related to general, technology, and healthcare cash flow loans. These actions were taken to lower the Company’s credit risk profile and improve its funding mix. As of December 31, 2017, $1.0 billion of the loans sold had settled, while $481.1 million were classified as held for sale. The loans held for sale at December 31, 2017 settled in the first quarter of 2018. In connection with the Cash Flow Loan Sale, we recognized $2.2 million in charge-offs during the fourth quarter of 2017 to record the loans at the lower of cost or fair value. 47 Federal Tax Reform The TCJA was signed into law on December 22, 2017 and represented the first major overhaul of the United States federal income tax system in more than 30 years. The TCJA reduced the federal corporate tax rate from 35% to 21% effective January 1, 2018. Other changes affecting us include immediate deductions for acquisitions of certain fixed assets instead of deductions for depreciation expense over time, modification of the deduction for performance-based executive compensation, and limiting the amount of FDIC insurance assessments that are deductible. The effective tax rates for 2018 and 2017 were 26.5% and 35.5%. Key Performance Indicators Among other factors, our operating results generally depend 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 if related to a quarterly period) 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 interest on certain loans and municipal securities based on a 21% federal statutory tax rate for 2018 and a 35% federal statutory tax rate for prior periods. Tax equivalent net interest margin is calculated as tax equivalent net interest income divided by 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. 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. Loan and Lease Growth We actively seek new lending opportunities under an array of lending products. Our lending activities include real estate mortgage loans, real estate construction and land loans, commercial loans and leases, and a small amount of consumer lending. Our commercial real estate loans and real estate construction loans are secured by a range of property types. Our commercial loans are diverse and generally include various asset-secured loans, equipment-secured loans and leases, venture capital loans to support venture capital firms’ operations and the operations of entrepreneurial companies during the various phases of their early life cycles, secured business loans originated through our Community Banking group, and loans to security alarm monitoring companies. Our loan origination process emphasizes credit quality. To augment our internal loan production, we have historically purchased multi-family loans from other banks. We have also purchased single-family mortgage and construction loans and private student loans from third-party lenders. These loan purchases help us manage the concentrations in our portfolio as they diversify the geographic, interest-rate risk, credit risk, and product composition of our loan portfolio. 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. 48 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 loans and leases, nonaccrual loans and leases, 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 classified loans and leases, the likelihood of loans defaulting based on the historical degree that similar loans defaulted and the resulting loss severity for these defaulted loans, 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. We regularly review our loans and leases to determine whether there has been any deterioration in credit quality resulting 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 unemployment rate, rate of inflation, increases in the general level of interest rates, declines in real estate values, changes in commodity prices, 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 our loans are concentrated in commercial real estate loans. The Level of Noninterest Expense Our noninterest expense includes fixed and controllable overhead, the largest components of which are compensation and occupancy expense. 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). 49 The following table presents the calculation of our efficiency ratio for the years indicated: Efficiency Ratio Noninterest expense . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

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 ultimately differ significantly from these estimates and assumptions, which could have a material adverse effect 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 and estimates 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 on loans and leases held for investment, accounting for business combinations, and the realization of deferred income tax assets and liabilities. Allowance for Credit Losses on Loans and Leases Held for Investment The allowance for credit losses on loans and leases held for investment 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. For loans and leases acquired and measured at fair value and deemed non-impaired on the acquisition date, our allowance methodology measures deterioration in credit quality or other inherent risks related to these acquired assets that may occur after the acquisition date. 50 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 has a general reserve component for unimpaired loans and leases and a specific reserve component for 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 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. Impaired loans and leases with outstanding balances less than or equal to $250,000 may not be individually assessed for impairment but are assessed with reserves based on the average loss severity on historical impaired loans with similar risk characteristics. Our allowance methodology for the general reserve component includes both quantitative and qualitative loss factors which are applied to our population of unimpaired loans and leases to estimate our general reserves. The quantitative loss factors consider the likelihood of loans defaulting based on the historical degree that similar loans defaulted and the degree of credit losses based on the historical average degree of loss experienced for these similar loans and leases pooled both by loan or lease type and credit risk rating; loans with more adverse credit risk ratings have higher quantitative loss factors. The qualitative loss factors consider, among other things, current economic trends and forecasts, current collateral values and performance trends, credit performance trends, and the loan portfolio’s current composition. As noted below in ‘‘—Allowance for Loan and Lease Losses—Change in Methodology,’’ we changed our methodology for calculating the ALLL in the second quarter of 2018. See that section for details regarding this change. The qualitative criteria we consider when establishing the loss factors include the following: (cid:129) current economic trends and forecasts; (cid:129) current collateral 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 51 (cid:129) changes in management related to credit administration functions. We estimate the reserve for unfunded loan commitments using the same loss factors as used for the allowance for loan and lease losses. The reserve for unfunded loan commitments is computed using expected future usage of the unfunded commitments based on historical usage of unfunded commitments for the various loan types. The allowance for credit losses is directly correlated to the credit risk ratings of our loans. 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 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 rated as ‘‘pass’’ are not adversely classified and collection and repayment in full are expected. (cid:129) Special Mention: Loans and leases rated 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 rated 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 rated as ‘‘doubtful’’ have all the weaknesses of those rated 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 6. Loans and Leases of the Notes to Consolidated Financial Statements contained in ‘‘Item 8. Financial Statements and Supplementary Data.’’ In addition to our internal risk rating process, our federal and state banking regulators, as an integral part of their examination process, periodically review the Company’s loan risk rating classifications. Our regulators may require the Company to recognize rating downgrades based on their judgments related to information available to them at the time of their examinations. Risk rating downgrades generally result in increases in the provisions for credit losses and the allowance for credit losses. Management believes the allowance for credit losses is appropriate for the known and inherent risks in our 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 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. 52 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 and Lease Losses—Change in Methodology The allowance for loan and lease losses (‘‘ALLL’’) represents management’s estimate of probable credit losses inherent in the loan portfolio as of the balance sheet date. Our methodology to estimate the ALLL has three basic elements that include specific reserves for individually evaluated impaired loans, a quantitative general allowance for all other loans (including individually evaluated loans determined not to be impaired), and qualitative adjustments based on other factors which may be internal or external to the Company. During the second quarter of 2018, we changed our methodology used to estimate the quantitative general allowance due to the growth and increased complexity of the loan portfolio. The new ALLL methodology included three primary changes: the quantitative component now employs a probability of default/loss given default (‘‘PD/LGD’’) methodology; the loan segmentation groups our loan portfolio into 21 loan pools with similar risk characteristics (as opposed to 34 loan pools used under the previous methodology); and the historical range of loan performance history, or look-back period, was lengthened by one year to ten years. The new PD/LGD methodology estimates the likelihood of loans defaulting based on the historical degree that similar loans defaulted, and it estimates the degree of credit loss based on the historical average degree of loss experienced for these similar loans. The reduced number of loan pools provides greater statistical validity by having more default and loss histories within each pool for the quantitative general allowance estimation. The look-back period was extended to capture loan performance back to January 1, 2009, one year longer than under the historical loss migration methodology. Extending this look-back period includes more historical loan performance information. The loss emergence period was unchanged as we continue to use seven quarters. The methodology to estimate specific reserves for individually evaluated impaired loans did not change. The methodology to derive qualitative adjustments based on other internal or external factors was updated to align with the new PD/LGD methodology being applied to estimate the quantitative general allowance for unimpaired loans. As a result, the composition of the ALLL changed as the quantitative component increased and the qualitative component decreased as the new quantitative methodology now encompasses more information, such as the longer look-back period, that previously required a qualitative adjustment as part of determining the total ALLL estimate. These changes in the ALLL methodology did not result in material changes to management’s overall ALLL estimate at June 30, 2018. 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. 53 Deferred Tax Assets and Liabilities Our deferred tax assets and liabilities 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. 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) 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.

We completed the acquisition of CUB on October 20, 2017, thereby impacting the comparability of the three years presented. This acquisition was accounted for using the acquisition method of accounting and, accordingly, CUB’s operating results have been included in the consolidated financial statements from its acquisition date. Earnings Performance 2018 Compared to 2017 Net earnings for the year ended December 31, 2018 were $465.3 million, or $3.72 per diluted share, compared to net earnings for the year ended December 31, 2017 of $357.8 million, or $2.91 per diluted share. The $107.5 million increase in net earnings was due to higher net interest income of $61.3 million, lower income tax expense of $28.9 million, a lower provision for credit losses of $12.8 million, and higher noninterest income of $20.1 million, offset partially by higher noninterest expense of $15.6 million. The increase in net interest income was due mainly to higher balances of average loans and leases and average investment securities and a higher yield on average loans and leases, offset partially by a lower yield on average investment securities and higher interest expense. The decrease in income tax expense was due primarily to the TCJA which reduced our effective tax rate to 26.5% for the year ended December 31, 2018 from 35.5% for 2017. The decrease in the provision for credit losses was due mainly to lower specific provisions for impaired loans during 2018, higher recoveries of charge-off loans during 2018, and lower amounts of loans rated special mention and classified at December 31, 2018 compared to December 31, 2017. The increase in noninterest income was due mostly to a higher gain on sale of securities of $8.7 million, higher warrant income of $4.9 million, higher other commissions and fees of $4.1 million, and higher other income of $3.7 million. The increase in noninterest expense was due mainly to higher compensation expense of $16.0 million, higher intangible asset amortization of $8.3 million, higher other professional services expense of $4.6 million, and higher occupancy expense of $4.4 million, offset partially by lower acquisition, integration and reorganization costs of $18.0 million. The increases in these expense 55 categories are primarily due to twelve months of CUB incremental operating expenses in 2018 compared to only 72 days of expense in 2017. 2017 Compared to 2016 Net earnings for the year ended December 31, 2017 were $357.8 million, or $2.91 per diluted share, compared to net earnings for the year ended December 31, 2016 of $352.2 million, or $2.90 per diluted share. The $5.7 million increase in net earnings was due to higher net interest income of $18.3 million, higher noninterest income of $16.1 million, a lower provision for credit losses of $8.0 million, and lower income tax expense of $8.9 million, offset partially by higher noninterest expense of $45.6 million. The increase in net interest income was attributable to higher average interest-earning asset balances, offset by lower discount accretion on acquired loans, lower yield on average loans and leases, and higher interest expense. The increase in noninterest income was due mainly to higher leased equipment income, higher gain on sale of loans and leases, lower FDIC loss sharing expense, and higher other income, offset partially by lower gain on sale of securities. The lower provision for credit losses was due primarily to lower general reserves of $14.1 million related to the sale of cash flow loans and lower amounts of loans rated special mention and classified at December 31, 2017 compared to December 31, 2016, offset partially by higher specific provisions for impaired loans during 2017. The increase in noninterest expense was due mostly to a $19.5 million increase in acquisition, integration and reorganization expense related to the CUB acquisition and incremental operating expenses of approximately $10 million for CUB’s operations post-acquisition, primarily compensation expense. 56 Net Interest Income 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, 2018 2017 2016 Average Balance Yields Interest Income/ and Expense Rates Average Balance Yields Interest Income/ and Expense Rates Average Balance Yields Interest Income/ and Expense Rates (Dollars in thousands) ASSETS: Loans and leases(1)(2) . . . . . . . $16,863,673 $1,048,984 Investment securities(3)(4) 118,605 . . . .

Starting with the third quarter of 2017, includes tax-equivalent adjustments related to tax-exempt interest on loans. Includes discount accretion on acquired loans of $29.3 million, $26.1 million, and $79.5 million for 2018, 2017, and 2016, respectively. Includes tax-equivalent adjustments of $6.5 million, $19.4 million, and $19.5 million for 2018, 2017, and 2016, respectively, related to tax-exempt interest on municipal securities. The federal statutory rate utilized was 21% for 2018 and 35% for 2017 and 2016. Tax equivalent. 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 total deposits divided by average total deposits. 57 Net interest income is affected by changes in both interest rates and the amounts of average interest-earning assets and interest-bearing liabilities. The changes in the amounts 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. The change in interest income/expense attributable to rate reflects the change in rate multiplied by the prior year’s volume. The change in interest income/expense not attributable specifically to either volume or rate is allocated ratably between the two categories. The following table presents changes in interest income/expense and related changes in volume and rate for the years indicated: 2018 Compared to 2017 2017 Compared to 2016 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(1) . . . . . . . . . . . . .

Tax equivalent. 2018 Compared to 2017 Net interest income increased by $61.3 million to $1.04 billion for the year ended December 31, 2018 compared to $979.6 million for the year ended December 31, 2017 due mainly to higher balances of average loans and leases and average investment securities and a higher yield on average loans and leases, offset partially by a lower yield on average investment securities and higher interest expense. The yield on average loans and leases was 6.22% for the year ended December 31, 2018 compared to 5.97% for 2017. The increase in the yield on average loans and leases was due mainly to repricing of variable-rate loans attributable to higher short-term market interest rates. 58 The tax equivalent NIM for the year ended December 31, 2018 was 5.05% compared to 5.10% for the year ended December 31, 2017. The decrease in the tax equivalent NIM was due mostly to a higher cost of average interest-bearing liabilities, a lower yield on average investment securities, and a decrease of six basis points resulting from a smaller tax equivalent adjustment due to the lower statutory federal tax rate, offset partially by the increase in the yield on average loans and leases as described above. The taxable equivalent adjustment for tax-exempt interest income on municipal securities contributed three basis points to the tax equivalent NIM for the year ended December 31, 2018 and ten basis points for 2017. The cost of average total deposits increased to 0.44% for the year ended December 31, 2018 from 0.27% for 2017 due mainly to higher rates paid on deposits in conjunction with increased market interest rates. 2017 Compared to 2016 Net interest income increased by $18.3 million to $979.6 million for the year ended December 31, 2017 compared to $961.3 million for the year ended December 31, 2016 due mainly to higher average interest-earning asset balances, offset partially by lower discount accretion on acquired loans, lower yields on average loans and leases, and higher interest expense. The loan and lease yield for the year ended December 31, 2017 was 5.97% compared to 6.32% for 2016. 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 $26.1 million for the year ended December 31, 2017 (16 basis points on the loan and lease yield) compared to $79.5 million for 2016 (55 basis points on the loan and lease yield). The tax equivalent NIM for the year ended December 31, 2017 was 5.10% compared to 5.40% for the year ended December 31, 2016. The decrease in the tax equivalent NIM was due mostly to lower discount accretion on acquired loans as described above. Total discount accretion on acquired loans contributed 14 basis points to the NIM for the year ended December 31, 2017 compared to 43 basis points for 2016. The taxable equivalent adjustment for tax-exempt interest income on municipal securities contributed 10 basis points to the tax equivalent NIM for the year ended December 31, 2017 and 11 basis points for 2016. The cost of average total deposits increased to 0.27% for the year ended December 31, 2017 from 0.20% for 2016 primarily as a result of the general increase in deposit rates during 2017 as a result of the Federal Reserve’s increases to federal funds rates. 59 Provision for Credit Losses The following table sets forth the details of the provision for credit losses on loans and leases held for investment and information regarding credit quality metrics for the years indicated: Year Ended December 31, 2018 Increase (Decrease) 2017 Increase (Decrease) 2016 (Dollars in thousands) Provision For Credit Losses: Addition to allowance for loan and lease losses . . . . . . . . . . . . . . . . . . . $ 36,774 $ (14,192) $ 50,966 $ (13,974) $ 64,940 Addition to reserve for unfunded loan commitments . . . . . . . . . . . . . . . . . .

Amounts and ratios related to 2017 and 2016 are for Non-PCI loans and leases held for investment, net of deferred fees. See ‘‘—Balance Sheet Analysis—Allowance for Credit Losses on Loans and Leases Held for Investment’’ for detail of charge-offs and recoveries by loan portfolio segment, class, and subclass for the periods presented. Provisions for credit losses are charged to earnings for both on and off-balance sheet credit exposures. The provision for credit losses on our loans and leases held for investment is based on our allowance methodology and is an expense that, in our judgment, is required to maintain an adequate allowance for credit losses. The allowance for loan and lease losses has a general reserve component for loans and leases with no credit impairment and a specific reserve component for impaired loans and leases. Our allowance methodology for the general reserve component includes both quantitative and qualitative loss factors that are applied against the population of unimpaired loans and leases. The quantitative loss factors consider the likelihood of loans defaulting based on the historical degree that similar loans defaulted and the degree of credit losses based on the historical average degree of loss experienced for these similar loans and leases pooled both by loan or lease type and credit risk rating; loans with more adverse credit risk ratings have higher quantitative loss factors. The qualitative loss factors consider, 60 among other things, current economic trends and forecasts, current collateral values and performance trends, credit performance trends, and the loan portfolio’s current composition. As noted in ‘‘—Critical Accounting Policies and Estimates—Allowance for Credit Losses on Loans and Leases Held for Investment—Allowance for Loan and Lease Losses—Change in Methodology,’’ we changed our ALLL methodology in the second quarter of 2018. See that section for details regarding this change. We recorded a provision for credit losses of $45.0 million, $57.8 million, and $65.7 million for the years ended December 31, 2018, 2017, and 2016. The provision for credit losses decreased by $12.8 million to $45.0 million for the year ended December 31, 2018 compared to $57.8 million for the year ended December 31, 2017 due mainly to lower specific provisions for impaired loans during 2018, higher recoveries of charged off loans during 2018, and lower amounts of loans rated special mention and classified at December 31, 2018 compared to December 31, 2017. Loans rated special mention and classified have a higher general reserve amount than loans rated pass. The provision for credit losses decreased by $8.0 million to $57.8 million for the year ended December 31, 2017 compared to $65.7 million for the year ended December 31, 2016 due primarily to lower general reserves of $14.1 million related to the sale of cash flow loans and lower amounts of loans rated special mention and classified at December 31, 2017 compared to December 31, 2016, offset partially by higher specific provisions for impaired loans during 2017. 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 unemployment rate, the rate of inflation, increases in the general level of interest rates, declines in real estate values, and adverse conditions in borrowers’ businesses.

The increase in gain on sale of securities was attributable to a net gain of $8.2 million on sales of $563.6 million of securities during the year ended December 31, 2018 compared to a net loss of $0.5 million on sales of $759.8 million of securities during 2017. The securities sold in 2018 include $299.9 million that were sold for a gain of $6.3 million in the first quarter of 2018 primarily for reinvestment in higher quality liquid assets, yield, and credit risk purposes. Warrant income increased due primarily to a $3.1 million gain on a warrant in a company that completed an IPO. Other commissions and fees increased due primarily to higher foreign exchange fees of $3.1 million and higher credit card fee income of $1.5 million. Other income increased due mainly to higher gains on early lease terminations and higher BOLI income, partially offset by lower legal settlements with former borrowers. 2017 Compared to 2016 Noninterest income increased by $16.1 million to $128.6 million for the year ended December 31, 2017 compared to $112.5 million for the year ended December 31, 2016 due primarily to increases in other income of $11.1 million, gain on sale of loans and leases of $5.3 million, leased equipment income of $3.8 million, and lower FDIC loss sharing expense of $8.9 million, offset partially by decreases in gain on sales of securities of $10.0 million and other commissions and fees of $5.7 million. The increase in other income was primarily due to legal settlements with former borrowers and other parties of $8.0 million. Leased equipment income increased due to a higher average balance of leased equipment in 2017 and higher gains from early lease terminations. 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 decrease in gain on sale of securities was due partly to the tax-related decision to sell $172.6 million of securities at a loss of $3.3 million in the fourth quarter of 2017. The decrease in other commissions and fees was mostly due to lower loan prepayment penalty fees.

Compensation expense increased due to higher salary expense of $11.9 million, higher stock compensation expense of $4.2 million, and higher bonus expense of $3.6 million, offset partially by lower severance and retention expense of $4.1 million. Intangible asset amortization increased due to the intangible assets added from the CUB acquisition in October 2017. Other professional services expense increased due primarily to higher consulting and legal expense. Occupancy expense increased due primarily to inclusion of the CUB operations for a full year in 2018. The acquisition, integration and reorganization costs for the year ended December 31, 2018 related to the terminated El Dorado Savings Bank merger agreement, while the costs for 2017 related to the CUB acquisition. 2017 Compared to 2016 Noninterest expense increased by $45.6 million to $495.7 million for the year ended December 31, 2017 compared to $450.1 million for the year ended December 31, 2016 due primarily to an increase in acquisition, integration and reorganization costs of $19.5 million related to the CUB acquisition and incremental operating expenses of approximately $10 million for CUB’s operations post-acquisition, mainly compensation expense. Income Taxes The effective tax rates were 26.5%, 35.5% and 36.9% for the years ended December 31, 2018, 2017, and 2016. The decrease in the effective tax rate for the year ended December 31, 2018 was due to the enactment of the TCJA, which reduced the federal statutory corporate tax rate to 21% effective January 1, 2018 from 35% in prior periods. The Company remeasured its federal deferred tax assets and liabilities as a result of the TCJA in its financial statements as of December 31, 2017. As a result of changes in total deferred tax assets and liabilities resulting from true-ups to the 2017 tax return, we recorded an additional $1.9 million of tax expense in 2018 to reflect the impact of the change in statutory rate under the TCJA. The Company considers its accounting for the effects of the TCJA to be complete. However, the legislation remains subject to potential amendments, technical corrections and further guidance at both the federal and state levels. The decrease in the effective tax rate for the year ended December 31, 2017 was primarily due to the reversal of an $11.6 million valuation allowance related to foreign tax credits that, based on a change in estimate in our 2017 analysis, were more likely than not to be utilized before they expire. The decrease in the effective tax rate for 2017 was also attributable, to a lesser extent, to tax benefits of $1.5 million recorded in 2017 due to the adoption of ASU 2016-09 on January 1, 2017, and a tax benefit of $1.2 million from remeasuring the federal deferred tax assets and liabilities as a result of the TCJA. The Company’s 2018 blended statutory tax rate for federal and state was 28.3%. For further information on income taxes, see Note 14.

See ‘‘Non-GAAP Measurements.’’ Fourth Quarter of 2018 Compared to Third Quarter of 2018 Net earnings were $115.0 million, or $0.93 per diluted share, for the fourth quarter of 2018 compared to $116.3 million, or $0.94 per diluted share, for the third quarter of 2018. The quarter-over-quarter decrease in net earnings of $1.2 million was due to lower noninterest income of $3.4 million, higher noninterest expense of $1.1 million and a higher provision for credit losses of $0.5 million partially offset by higher net interest income of $1.4 million. 64 Net interest income increased by $1.4 million to $261.8 million for the fourth quarter of 2018 compared to $260.3 million for the third quarter of 2018 due mainly to a higher yield on average loans and leases and a higher balance of average loans and leases, offset partially by higher deposit costs. The tax equivalent yield on average loans and leases was 6.27% for the fourth quarter of 2018 compared to 6.20% for the third quarter of 2018. The increase in the yield on average loans and leases was due principally to higher coupon interest. The tax equivalent NIM was 4.91% for the fourth quarter of 2018 compared to 4.99% for the third quarter of 2018. The decrease in the NIM was due mainly to higher deposit and borrowing costs. The cost of average total deposits increased to 0.62% for the fourth quarter of 2018 from 0.46% for the third quarter of 2018 due to higher rates paid on deposits in conjunction with increased market rates. The provision for credit losses increased by $0.5 million to $12.0 million for the fourth quarter of 2018 compared to $11.5 million for the third quarter of 2018. Noninterest income decreased by $3.4 million to $33.5 million for the fourth quarter of 2018 compared to $36.9 million for the third quarter of 2018 due mainly to a $4.2 million decrease in dividends and gain on equity investments, a $1.6 million decrease in warrant income, and a $1.3 million decrease in other commissions and fees, offset partially by a $3.4 million increase in other income. Dividends and gains on equity investments decreased due mainly to lower realized gains on investments sold and decreased fair values of investments still held. Warrant income decreased due to lower realized gains on exercised warrants as the third quarter included a $3.1 million gain on a warrant in a company that completed an IPO. Other commissions and fees decreased due mostly to lower prepayment and other loan-related fees. Other income increased due primarily to higher miscellaneous income from borrower settlements and higher BOLI income from a death benefit received. Noninterest expense increased by $1.1 million to $129.2 million for the fourth quarter of 2018 compared to $128.2 million for the third quarter of 2018 attributable primarily a $3.7 million increase in other expense, offset partially by a $3.0 million decrease in compensation expense. Other expense increased due to the $2.1 million write-off of the Square 1 trademark asset as a result of our plan to retire the Square 1 Bank name and increased employee expense due to executive relocation costs. Compensation expense decreased due mostly to lower stock compensation expense, lower bonus expense, and lower commissions expense as a result of the decreased warrant income. 65 Balance Sheet Analysis Securities Available-for-Sale Our securities available-for sale portfolio consists primarily of obligations of states and political subdivisions (‘‘municipal securities’’) and U.S. government agency and government-sponsored enterprise (‘‘agency’’) obligations.

The changes during 2018 in the portfolio classes comprising these portfolio segments reflected the following: (cid:129) Commercial real estate mortgage loans decreased by 10% to $4.8 billion or 27% of total loans and leases held for investment at December 31, 2018 from $5.4 billion or 32% at December 31, 2017. The lower balance and composition ratio was attributable primarily to the balance of healthcare real estate loans declining to $451.8 million at December 31, 2018 from $843.7 million at December 31, 2017. This decline in new healthcare real estate lending was the result of fewer loan opportunities meeting our credit standards. (cid:129) Income producing and other residential real estate mortgage loans increased by 25% to $3.1 billion or 17% of total loans and leases held for investment at December 31, 2018 from $2.5 billion or 14% at December 31, 2017. The higher balance and composition ratio was attributable to our continued emphasis on originating and purchasing multi-family secured real estate mortgage loans during 2018 due primarily to the favorable credit risk profile of those loans. (cid:129) Commercial real estate construction and land loans increased by 19% to $912.6 million or 5% of total loans and leases held for investment at December 31, 2018 from $769.1 million or 5% at December 31, 2017. The higher balance and comparable composition ratio was attributable to our continued emphasis on these types of loans and balances on existing loans increasing as disbursements occur during the construction phase. (cid:129) Residential real estate construction and land loans increased by 61% to $1.3 billion or 8% of total loans and leases held for investment at December 31, 2018 from $822.2 million or 5% at December 31, 2017. The higher balance and composition ratio was attributable to our continued emphasis on originating multi-family secured real estate construction loans in markets with strong demand for new multi-family housing. (cid:129) Asset-based loans and leases increased by 13% to $3.3 billion or 18% of total loans and leases held for investment at December 31, 2018 from $2.9 billion or 17% at December 31, 2017. The higher balance and composition ratio was due primarily to net loan growth in lender finance & timeshare loans and premium finance loans attributable to continued emphasis on originations for these loan types because of their favorable historical credit performance. Lender finance & timeshare loans increased to $1.8 billion at December 31, 2018 from $1.6 billion at December 31, 2017, and premium finance loans increased to $356.4 million at December 31, 2018 from $232.7 million at December 31, 2017. (cid:129) Venture capital loans decreased by 4% to $2.0 billion or 11% of total loans and leases held for investment at December 31, 2018 from $2.1 billion or 13% at December 31, 2017. The lower balance and composition ratio was attributable primarily to lower early stage and late stage loans to venture-backed companies, offset partially by higher equity fund loans. The increase in equity fund loans was due to continued emphasis on originations because of favorable historical credit performance. Early stage loans and late stage loans decreased to $225.6 million and $107.6 million at December 31, 2018 from $443.4 million and $255.0 million at December 31, 2017. Equity fund loans increased to $797.5 million at December 31, 2018 from $471.2 million at December 31, 2017. 69 (cid:129) Other commercial loans decreased by 1% to $2.06 billion or 12% of total loans and leases held for investment at December 31, 2018 from $2.07 billion or 12% at December 31, 2017. The lower balance was attributable primarily to lower cash flow loans, which decreased to $114.1 million at December 31, 2018 from $278.9 million at December 31, 2017.

For any of these loans and leases held for investment, 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 have performed in accordance with their contractual terms. The circumstances 71 regarding any modifications and a borrower’s specific situation, such as its ability to obtain financing from another source at similar market terms, are evaluated on an individual basis to determine if our contractual loan renewal or loan extension constitutes a TDR. Higher levels of TDRs generally lead to increases in classified loans and credit loss provisions.

Charge-offs related to 2017 and prior years are for Non-PCI loans and leases. Charge-offs by portfolio class and subclass not available. 74 Gross charge-offs within the real estate mortgage portfolio segment increased by $5.8 million in 2018, of which $4.3 million, or 75%, related to a single credit for a traditional mall that was foreclosed upon and sold during 2018. Gross charge-offs within the venture capital portfolio class decreased from $40.3 million in 2017 to $33.0 million in 2018. Similar to 2017, the charge-offs in 2018 were driven by specific borrower events and not indicative of any trends as venture capital loan charge-offs tend to be idiosyncratic in nature. Four loans, two in the early stage and two in the expansion stage, accounted for $26.8 million, or 81%, of the venture capital gross charge-offs for 2018. Gross charge-offs within the commercial cash flow portfolio subclass decreased significantly from $27.5 million in 2017 to $9.9 million in 2018, reflecting our decision to sell most of this portfolio in 2017, while $6.7 million, or 67%, of the 2018 gross charge-offs related to one borrower. 75 The following table presents recoveries by portfolio segment, class, and subclass for the periods indicated: Allowance for Credit Losses Recoveries(1) 2018 2017 2016 2015 2014(2) Year Ended December 31, (In thousands) Real estate mortgage: Healthcare real estate . . . . . . . . . . . . . . . . . . . . . .

Amounts and ratios related to 2017 and prior years are for Non-PCI loans and leases. The changes in the allowance by portfolio segment at December 31, 2018 compared to December 31, 2017 were due to the following: (cid:129) The real estate mortgage allowance increased due to a higher amount of unamortized purchase discount at December 31, 2017 related to real estate mortgage loans purchased in connection with the acquisition of CUB on October 20, 2017. Such purchase discount offsets the allowance for loan and lease losses related to these purchased loans. (cid:129) The real estate construction and land allowance increased due to net loan growth in this portfolio segment and a higher balance of special mention rated loans at December 31, 2018. Special mention loans have a higher allowance for loans and lease losses. (cid:129) The commercial allowance decreased due to a lower amount of specific reserves on impaired commercial loans at December 31, 2018. 77 Deposits The following table presents a summary of our average deposit amounts and average rates paid during the years indicated: Deposit Category Year Ended December 31, 2018 2017 2016 Average Amount Weighted Average Rate Average Amount Weighted Average Rate Average Amount Weighted Average Rate (Dollars in thousands) Interest checking deposits . .

Nonaccrual Loans and Leases Held for Investment Nonaccrual loans and leases held for investment decreased by $78.2 million during 2018 to $79.3 million at December 31, 2018 due mainly to $56.0 million in charge-offs, the sale of a $44.6 million nonaccrual healthcare real estate loan, $16.6 million in transfers to foreclosed assets, and $74.7 million in principal payments and other reductions, offset partially by $113.6 million in nonaccrual additions.

Performing TDRs held for investment decreased by $39.1 million during 2018 to $17.7 million at December 31, 2018 due primarily to the removal of a $29.4 million commercial real estate mortgage loan from TDR status due to the loan being renewed at current market terms with no concessions granted and the borrower not experiencing financial difficulties, and payoffs and other reductions of $11.6 million, offset partially by new additions of $1.6 million. The majority of the number of performing TDRs were on accrual status prior to the restructurings and have remained on accrual status after the restructurings due to the borrowers making payments before and after the restructurings.

Amounts and ratios related to 2017 and 2016 are for Non-PCI loans and leases held for investment, net of deferred fees. Changes in special mention and classified loans and leases measured from one period-end to the next derive from the net changes in loans and leases newly entering the special mention and classified categories, the loans and leases that migrated out of these categories, and the balance changes in these loans. 83 At December 31, 2018, special mention loans and leases declined to $261.4 million from $302.2 million at December 31, 2017. The lower amount of special mention loans and leases at December 31, 2018 compared to December 31, 2017 was due mainly to the decline in special mention healthcare real estate loans to $11.9 million at December 31, 2018 from $67.2 million at December 31, 2017 and to our exiting our National Lending origination operations related to general, technology, and healthcare cash flow loans. At December 31, 2018, there were no special mention loans related to these exited lending areas, and at December 31, 2017, special mention loans related to these exited lending areas were $7.3 million. The decrease in special mention loans and leases by loan portfolio class was attributable mainly to a $47.7 million decrease in special mention commercial real estate mortgage loans and a $36.6 million decrease in special mention venture capital loans, offset partially by a $28.3 million increase in special mention other commercial loans and an $11.1 million increase in special mention asset-based loans. The decrease in our special mention commercial real estate mortgage loans was due mainly to the decrease in our special mention healthcare real estate loans. At December 31, 2018, classified loans and leases declined to $237.1 million from $278.4 million at December 31, 2017. The lower amount of classified loans and leases at December 31, 2018 compared to December 31, 2017 was due mainly to the decline in classified healthcare real estate loans to $0.1 million at December 31, 2018 from $63.9 million at December 31, 2017 and to our exiting our National Lending origination operations related to general, technology, and healthcare cash flow loans. At December 31, 2018 and 2017, classified loans related these exited lending areas were $14.8 million and $39.0 million. The decrease in classified loans and leases by loan portfolio class was attributable primarily to a $36.1 million decrease in classified commercial real estate mortgage loans and a $20.9 million decrease in classified venture capital loans, offset partially by a $17.3 million increase in classified other commercial loans. The decrease in our classified commercial real estate mortgage loans was due mainly to the decrease in our classified healthcare real estate loans. 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, 2018, 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, 2018, such disallowed amounts were $489,000 for the Company and $39,000 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 requires all banking organizations to maintain a capital conservation buffer above the minimum risk-based capital requirements 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, 2018, the Company and Bank were in compliance with the capital conservation buffer requirement. Effective January 1, 2019, the capital conservation buffer increased by 0.625% to its fully phased-in 2.5%, such that the common equity 84 tier 1, tier 1 and total capital ratio minimums inclusive of the capital conservation buffer were 7.0%, 8.5%, and 10.5%. 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 Plus Capital Conservation Buffer Phase-In(1) For Well Capitalized Requirement Plus Capital Conservation Buffer Fully Phased-In December 31, 2018 PacWest Bancorp Consolidated Tier 1 capital (to average assets) . . . . .

The capital conservation buffer increases by 0.625% each year through 2019. 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 $453.8 million at December 31, 2018. At December 31, 2018, none of the trust preferred securities were included in the Company’s Tier I capital under the phase-out limitations of Basel III, and $440.2 million were included in Tier II capital. For a more detailed discussion of our subordinated debentures, see ‘‘Item 1: Business—Supervision and Regulation—Capital Requirements.’’ 85 During the first quarter of 2018, we redeemed $12.4 million of subordinated debentures assumed in connection with the CUB acquisition. 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’’) that 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 securities available-for-sale, which we refer to as our primary liquidity. We also maintain available borrowing capacity under secured credit lines with the FHLB and the FRBSF, which we refer to as our secondary liquidity. As a member of the FHLB, the Bank had secured borrowing capacity with the FHLB of $3.7 billion at December 31, 2018, of which $2.7 billion was available on that date. The FHLB secured credit line was collateralized by a blanket lien on $5.4 billion of qualifying loans. The Bank also had secured borrowing capacity with the FRBSF of $2.0 billion at December 31, 2018, all of which was available on that date. The FRBSF secured credit line was collateralized by liens on $2.7 billion of qualifying loans. In addition to its secured lines of credit, the Bank also maintains unsecured lines of credit for the purpose of borrowing overnight funds, subject to availability, of $141.0 million with the FHLB and $180.0 million in the aggregate with several correspondent banks. As of December 31, 2018, there was a $141.0 million balance outstanding related to the FHLB unsecured line of credit. The Bank is a member of the AFX, 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, 2018, the Bank had borrowed $190.0 million through the AFX. 86 The following tables provide a summary of the Bank’s primary and secondary liquidity levels as of the dates indicated: Primary Liquidity—On-Balance Sheet December 31, 2018 2017 2016 Cash and due from banks . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The Company’s secondary liquidity decreased by $513.9 million during 2018 due mainly to a $708.0 million increase in advances outstanding on the secured credit line with the FHLB and a $43.0 million decrease in the borrowing capacity on that secured credit line, offset partially by a $237.1 million increase in the borrowing capacity on the secured credit line with the FRBSF attributable to an increase in loan collateral resulting from pledging construction loans. In addition to our primary liquidity, we generate liquidity from cash flows from our loan and securities portfolios and our large base of core customer deposits, defined as noninterest-bearing demand, interest checking, savings, and non-brokered money market accounts. At December 31, 2018, core deposits totaled $16.3 billion and represented 87% of the Company’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. We evaluate the stability of deposit relationships through a deposit scorecard process, considering factors such as balance, transactional activity, length of relationship, interest rate sensitivity, and utilization of other Bank products. The deposit scorecard results are used as an input for our liquidity stress test, which we routinely conduct as part of our liquidity management process. Our deposit balances may decrease if interest rates increase significantly or if 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. 87 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, 2018, brokered deposits totaled $1.3 billion, consisting of $729.4 million of brokered time deposits, $518.2 million of non-maturity brokered accounts, and $3.7 million of other brokered deposits. At December 31, 2017, brokered deposits totaled $1.6 billion, consisting of $732.2 million of brokered time deposits, $835.6 million of non-maturity brokered accounts, and $7.5 million of other brokered deposits. Our liquidity policy includes guidelines for On-Balance Sheet Liquidity (a measurement of primary liquidity to total deposits plus borrowings), Liquidity Buffer Coverage Ratio (the ratio of cash and unpledged securities to the estimated 30 day cash outflow in a defined stress scenario), Liquidity Stress Test Survival Horizon (the number of days that the Bank’s liquidity buffer plus available secured borrowing capacity is sufficient to offset cumulative cash outflow in a defined stress scenario), Loan to Funding Ratio (measurement of gross loans net of fees divided by deposits plus 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, 2018, we were in compliance with all of our established liquidity guidelines. 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. The 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 the three previous fiscal years less any dividends paid during such period. Dividends paid by the Bank during the three previous fiscal years exceeded the Bank’s net earnings during that same period by $28.5 million. During the year ended December 31, 2018, PacWest received $684.0 million in dividends from the Bank. Since the Bank had an accumulated deficit of $643.9 million at December 31, 2018, for the foreseeable future, any dividends from the Bank to the holding company will continue to require DBO and FDIC approval. At December 31, 2018, PacWest had $242.9 million in cash and due from banks, 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, which terminates on February 29, 2020. See ‘‘—Recent Events—Stock Repurchase Program’’ for additional information. 88 Contractual Obligations The following table summarizes the known contractual obligations of the Company as of the date indicated: Time deposits(1) . . . . . . . . . . . . . . . . . . .

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, 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 commitments, of which only a portion is expected to be funded, and standby letters of credit. At December 31, 2018, our loan commitments and standby letters of credit were $7.5 billion and $364.2 million. The loan commitments, a portion of which result in funded loans, 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. 89 ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Market Risk—Foreign Currency Exchange We enter into foreign exchange contracts with our clients and counter-party banks primarily for the purpose of offsetting or hedging clients’ foreign currency exposures arising out of commercial transactions, and we enter into cross currency swaps and foreign exchange forward contracts to hedge exposures to loans and debt instruments denominated in foreign currencies. 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, and the derivative instruments that hedge those exposures. As of December 31, 2018, the U.S. Dollar notional amounts of loans receivable and subordinated debentures payable denominated in foreign currencies were $48.3 million and $29.6 million, and the U.S. Dollar notional amounts of derivatives outstanding to hedge these foreign currency exposures were $51.3 million and $29.2 million. We recognized foreign currency translation net gains of $0.3 million, $0.3 million, and $0.5 million for the years ended December 31, 2018, 2017, and 2016, respectively. 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, 2018, the results of which are presented below. Our NII simulation indicates that our balance sheet is asset-sensitive, while our MVE model indicates that our balance sheet had a slightly liability-sensitive profile. An asset-sensitive profile would suggest 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 NII that would result over the next 12 months from immediate and sustained changes in interest rates as of December 31, 2018. 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 NII forecasted using both increasing and decreasing interest rate scenarios using the forward yield curve at December 31, 2018. In order to arrive at the base case, we extend our balance sheet at December 31, 2018 one year and reprice any assets and liabilities that would contractually reprice or mature during that period using the products’ pricing as of December 31, 2018. Based on such repricing, we calculate an estimated tax equivalent NII and NIM for each rate scenario. 90 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 interest-bearing deposits reprice at our discretion and are assumed to reprice at a rate less than the change in market rates. The 12 month NII simulation model as of December 31, 2018 assumes interest-bearing deposits reprice at 46% of the change in market rates (this is commonly referred to as the ‘‘deposit beta’’). The effects of certain balance sheet attributes, such as fixed-rate loans, variable-rate loans that have reached their floors, and the volume of noninterest-bearing deposits as a percentage of earning assets, impact our assumptions and consequently the results of our NII simulation model. Changes that could vary significantly from our assumptions include loan and deposit growth or contraction, loan and deposit pricing, 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 forecasted net interest income and net interest margin for the next 12 months using the static balance sheet and forward yield curve as the base scenario, with immediate and sustained parallel upward and downward movements in interest rates of 100, 200 and 300 basis points as of the date indicated: Forecasted Net Interest Income (Tax Equivalent) Percentage Change From Base Forecasted Net Interest Margin (Tax Equivalent) Forecasted Net Interest Margin Change From Base December 31, 2018 Interest Rate Scenario: Up 300 basis points . . . . . . . . . . . . . . . . .

The $17.6 million decrease in year 1 tax equivalent NII was attributable to higher cost of funds and an increase in the mix of interest-bearing liabilities, offset partially by the positive impact from loan portfolio growth. 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. The most favorable alternate rate vector that we model is the ‘‘Bear Flattener’’ scenario, when short-term rates increase faster than long-term rates, and the least favorable alternate rate vector that we model is the ‘‘Bull Steepener,’’ when short-term rates fall faster than long-term rates. In the ‘‘Bear Flattener’’ scenario, Year 1 tax equivalent NII increases by 0.3%, and in the ‘‘Bull Steepener’’ scenario, Year 1 tax equivalent NII decreases by 2.1%. Of the $18.0 billion of total loans in the portfolio, $11.0 billion have variable interest rate terms (excluding hybrid loans discussed below). At December 31, 2018, $10.9 billion of these variable-rate loans have a loan rate higher than their floor rate, which allows them to reprice at their next reprice date upon a change in their index. Approximately 52% of the variable-rate loans (excluding hybrid loans) have a LIBOR index rate. Of the $186 million of loans with rates below their floor rates at December 31, 2018, $174 million (93.6%) will rise above their floor rates with a 100 basis point increase in market rates. LIBOR is expected to be phased out after 2021, as such the Company is assessing the impacts of this transition and exploring alternatives to use in place of LIBOR. The 91 business processes impacted relate primarily to our variable-rate loans and our subordinated debentures, both of which are indexed to LIBOR. Additionally, approximately $3.3 billion of 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 $286 million, $551 million, and $1.2 billion 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, 2018. The following table shows the projected change in the market value of equity for the set of rate scenarios presented as of the date indicated: December 31, 2018 Interest Rate Scenario: Projected Market Value of Equity Dollar Change From Base Percentage Change From Base Percentage of Total Assets (Dollars in millions) Ratio of Projected Market Value to Book Value Up 300 basis points . . . . . . . . . . . . . . .

The projected market value of equity decreased by $1.1 billion, while our overall MVE sensitivity profile has remained relatively unchanged. The decrease in base case market value of equity was due primarily to: (1) a $1.0 billion decrease in the mark-to-market adjustment for loans and leases resulting from higher credit spreads used for the loan value calculation and (2) a $152 million decrease in the book value of stockholders’ equity, offset partially by (3) a $122 million decrease in the mark-to-market adjustment for total deposits due to the overall increase in the level of market interest rates. The decrease in the book value of stockholders’ equity was due mainly to $306 million of common stock repurchases under the Stock Repurchase Program, $288 million of cash dividends paid, and a $37 million decline in accumulated other comprehensive income, offset partially by $465 million in net earnings. 92 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, 2018, 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, 2018, 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, 2018. The report, which expresses an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2018, is included in this Item under the heading ‘‘Report of Independent Registered Public Accounting Firm.’’ 94 Report of Independent Registered Public Accounting Firm To the Stockholders and Board of Directors PacWest Bancorp: Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting We have audited the accompanying consolidated balance sheets of PacWest Bancorp and subsidiaries (the Company) as of December 31, 2018 and 2017, 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, 2018, and the related notes (collectively, the consolidated financial statements). We also have audited the Company’s internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2018, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Basis for Opinions The Company’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 the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. 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. 95 Definition and Limitations of Internal Control Over Financial Reporting 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. /s/ KPMG LLP We have served as the auditor for the Company or its predecessors since 1982.

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 Beverly Hills, 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. The Bank is 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 74 full-service branches located throughout the State of California, one branch located in Durham, North Carolina, and numerous loan production offices across the country through our Community Banking, National Lending and Venture Banking groups. Community Banking provides real estate loans, commercial loans, and comprehensive deposit and treasury management services to small and medium-sized businesses conducted primarily through our California-based branch offices. National Lending provides asset-based, equipment, real estate, and security cash flow loans and treasury management services to established middle-market businesses on a national basis. Venture Banking 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. 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 treasury management and investment management services. Our major operating expenses are the interest paid by the Bank on deposits and borrowings, compensation, occupancy, and general operating expenses. (a) Accounting Standards Adopted in 2018 Effective January 1, 2018, the Company adopted ASU 2016-01, ‘‘Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities’’ and ASU 2018-03, ‘‘Technical Corrections and Improvements to Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.’’ ASU 2016-01 contained a number of changes which are applicable to the Company including the following: (1) requires equity investments to be measured at fair value with changes in fair value recognized in net income; (2) allows equity investments without readily determinable fair values to be measured at cost less impairment, if any, plus or minus changes in observable prices (referred to as the ‘‘measurement alternative’’); and (3) changes certain presentation and disclosure requirements for financial instruments, including using the exit price notion when measuring the fair value of financial instruments (see Note 13. Fair Value Measurements). ASU 2018-03 also clarified certain aspects of the guidance issued in ASU 2016-01, including requiring a prospective transition approach for equity investments without readily determinable fair value in which the measurement alternative is applied. 102 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) ASU 2016-01 does not apply to investments accounted for using the equity method, investments in consolidated subsidiaries, FHLB stock, and investments in low income housing tax credit projects accounted for under Topic 323, ‘‘Investments—Equity Method and Joint Ventures.’’ Upon adoption of ASU 2016-01, the Company recorded a transition adjustment to reclassify $529,000 in net unrealized gains from accumulated other comprehensive income (‘‘AOCI’’) to retained earnings. The ASU also eliminated the requirement to classify equity investments into different categories such as ‘‘Available-for-sale.’’ The adoption of this ASU may result in more earnings volatility as changes in fair value of certain equity investments are recorded in the statement of earnings as opposed to AOCI. Effective January 1, 2018, the Company early-adopted ASU 2018-02, ‘‘Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.’’ The TCJA required deferred tax assets and liabilities to be re-measured at its enactment date for the effect of the change in the federal corporate tax rate. This process resulted in ‘‘stranded tax effects’’ in AOCI for deferred tax asset or liabilities which were established with an offsetting amount in AOCI. ASU 2018-02 allows for a reclassification of the stranded tax effects resulting from the enactment of the TCJA from AOCI to retained earnings. The Company elected to reclassify all of its stranded tax effects of $6.665 million from AOCI to retained earnings effective January 1, 2018, while no other income tax effects related to the application of the TCJA were reclassified. Effective January 1, 2018, the Company adopted ASU 2014-09, ‘‘Revenue Recognition (Topic 606): Revenue from Contracts with Customers.’’ ASU 2014-09 supersedes Topic 605, ‘‘Revenue Recognition’’ and requires an entity to recognize revenue at an amount that reflects the consideration to which it expects to be entitled to in exchange for the transfer of promised goods or services to customers. Substantially all of the Company’s revenue is interest income on loans, investment securities, and deposits at other financial institutions which are specifically outside the scope of ASU 2014-09. ASU 2014-09 applies primarily to certain noninterest income items in the Company’s consolidated statement of earnings. Upon adoption, the Company applied the cumulative effect transition method, which resulted in no adjustment to retained earnings and no material impact on the Company’s consolidated financial position, results of operations, or cash flows. The Company did make minor changes to accounting operations and internal controls as part of adopting this new standard. See Note 16. Revenue From Contracts With Customers for further details. Effective January 1, 2018, the Company adopted ASU 2016-15, ‘‘Classification of Certain Cash Receipts and Cash Payments.’’ Upon adoption, the Company applied the retrospective transition method to each period presented. ASU 2016-15 addressed eight issues related to the statement of cash flows, the most relevant to the Company being the classification of proceeds from the settlement of BOLI policies. As the Company classified proceeds from the settlement of BOLI policies in the manner required by ASU 2016-15 in the prior periods presented, there was no change to the Company’s consolidated financial position, results of operations, or cash flows for both current and prior periods upon adoption. 103 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Effective January 1, 2018, the Company adopted ASU 2016-18, ‘‘Statement of Cash Flows (Topic 230): Restricted Cash.’’ Upon adoption, the Company applied the retrospective transition method to each period presented. As the Company does not present restricted cash as a separate line in the statement of financial position, there is no change to the presentation of cash on the statement of cash flows. The nature and amount of our restricted cash is shown in Note 2. Restricted Cash Balances. Effective January 1, 2018, the Company adopted ASU 2017-01, ‘‘Business Combinations (Topic 805): Clarifying the Definition of a Business.’’ ASU 2017-01 provides a new framework for determining whether transactions should be accounted for as acquisitions of assets or businesses. The Company had no acquisitions or purchases of components of a business in 2018, thus, the impact of adopting the new standard had no impact on the Company’s consolidated financial position, results of operations, or cash flows. Effective January 1, 2018, the Company adopted ASU 2017-09, ‘‘Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting.’’ ASU 2017-09 provided clarification of what constitutes a modification of a share-based payment award. The Company did not modify any share-based payment awards in 2018, thus, the impact of adopting the new standard had no impact on the Company’s consolidated financial position, results of operations, or cash flows. (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. In the opinion of management, all significant intercompany accounts and transactions have been eliminated and adjustments, consisting solely of normal recurring accruals and considered necessary for the fair presentation of financial statements have been included. (c) Use of Estimates We have made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the 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, the fair value estimates of assets acquired and liabilities assumed in acquisitions and the realization of deferred tax assets/liabilities. These estimates may be adjusted as more current information becomes available, and any adjustment may be significant. The allowance for loan and lease losses (‘‘ALLL’’) represents management’s estimate of probable credit losses inherent in the loan portfolio as of the balance sheet date. During the second quarter of 2018, the Company changed its ALLL methodology due to the growth and increased complexity of the loan portfolio. The new ALLL methodology included three primary changes: the quantitative component now employs a probability of default/loss given default (‘‘PD/LGD’’) methodology; the loan segmentation groups our loan portfolio into 21 loan pools with similar risk characteristics (as opposed to 34 loan pools used under the previous methodology); and the historical range of loan performance history (often referred to as the look-back period) was lengthened by one year to ten years. The 104 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) methodology for assessing individually impaired loans did not change under the new ALLL methodology. The ALLL methodology used to derive qualitative adjustments based on other internal or external factors was updated to align with the new PD/LGD methodology being applied to estimate the quantitative general allowance for unimpaired loans. As a result, the composition of the ALLL changed as the quantitative component increased and the qualitative component decreased as the new quantitative methodology now encompasses more information, such as the longer look-back period, that previously required a qualitative adjustment as part of determining the total ALLL estimate. These changes in the ALLL methodology did not result in material changes to management’s overall estimate of the ALLL at June 30, 2018. As described in Note 3. Acquisitions below, we completed the CUB acquisition on October 20, 2017. The acquired assets and liabilities in this acquisition 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 this transaction. (d) Reclassifications Certain prior period amounts have been reclassified to conform to the current period’s presentation format. In our loan and allowance tables, we realigned our commercial loan portfolio classes and subclasses to better reflect and report our lending, especially in light of the fourth quarter of 2017 cash flow loan sale and the exiting of the origination operations related to general, technology, and healthcare cash flow loans. Prior to the realignment, our commercial loan portfolio classes were: (1) asset-based, (2) venture capital, (3) cash flow, and (4) equipment finance. After the realignment, our commercial loan portfolio classes are (1) asset-based (which includes equipment finance), (2) venture capital, and (3) other commercial (which includes retained cash flow). All of the loan and allowance tables, both current period and prior periods, reflect this realignment. Prior to January 1, 2018, our credit quality disclosures were only for Non-PCI loans and leases. As our gross PCI loan portfolio reduced to less than 0.4% of total loans and leases as of the end of 2017, beginning in 2018 the credit quality disclosures reflect our entire loan and lease portfolio. Accordingly, for the credit quality tables in Note 6. Loans and Leases, amounts related to 2018 are for total loans and leases, while amounts related to 2017 and 2016 are for Non-PCI loans and leases. (e) Cash and Cash Equivalents For purposes of the consolidated statements of cash flows, cash and cash equivalents consist of: (1) cash and due from banks, and (2) interest-earning deposits in financial institutions. Interest-earning deposits in financial institutions represent mostly cash held at the FRBSF, the majority of which is immediately available. (f) 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. Securities held-to-maturity are stated at amortized cost. We do not classify any securities as held-to-maturity. 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 105 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) 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. Premiums on callable securities are amortized to the earliest call date. 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. Our accounting policy for investment securities applied to both debt and equity securities in prior periods. Effective January 1, 2018, upon the adoption of ASUs 2016-01 and 2018-03, our accounting policy for investment securities applies only to debt securities. Our accounting policy for equity investments is described in (o) below. (g) 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. 106 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 discounts or premiums on acquired non-impaired loans are 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. Purchased credit impaired loans are referred to as PCI loans and 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. As our gross PCI loan portfolio represented less than 0.4% of total loans as of the end of 2017, beginning in 2018 the PCI loans were accounted for as Non-PCI loans. Leases. We provide equipment financing to our customers through a variety of lease arrangements. For direct financing leases, lease receivables are recorded on the balance sheet but the leased property is not, although we generally retain 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’’ in the consolidated statements of earnings, 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, on occasion 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. The unamortized balance of net deferred fees and costs associated with loans held for sale are not accreted or amortized to interest income until the related loans are sold. Gains or losses on the sale of these loans are recorded as ‘‘Noninterest income’’ in the consolidated statements of earnings. 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. 107 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) 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 or lease generally when a borrower’s principal or interest payments or a lessee’s 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 payments past due 90 days or leases with payments past due 90 days may be accruing if the loans or leases are concluded to be well-secured and in the process of collection; however, these loans or leases are still reported as nonperforming. When loans or leases are placed on nonaccrual status, all interest previously accrued but not collected is reversed against current period interest income. Interest on nonaccrual loans or leases is subsequently recognized only to the extent that cash is received and the loan principal balance or lease balance is deemed collectable. Loans or leases are restored to accrual status when the loans or 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 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 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 108 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) 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. (h) Allowance for Credit Losses on Loans and Leases Held for Investment The allowance for credit losses on loans and leases held for investment 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. For loans and leases acquired and measured at fair value and deemed non-impaired on the acquisition date, our allowance methodology measures deterioration in credit quality or other inherent risks related to these acquired assets that may occur after the acquisition date. The allowance for 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 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 has a general reserve component for unimpaired loans and leases and a specific reserve component for 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 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. Impaired loans and leases with outstanding balances less than or equal to $250,000 may not be individually assessed for impairment but are assessed with reserves based on the average loss severity on historical impaired loans with similar risk characteristics. Our allowance methodology for the general reserve component includes both quantitative and qualitative loss factors which are applied to our population of unimpaired loans and leases to estimate our general reserves. The quantitative loss factors consider the likelihood of loans defaulting based on the historical degree that similar loans defaulted and the degree of credit losses based on the historical average degree of loss experienced for these similar loans and leases pooled both by loan or lease type and credit risk rating; loans with more adverse credit risk ratings have higher quantitative loss factors. The qualitative loss factors consider, among other things, current economic trends and forecasts, current collateral values and performance trends, credit performance trends, and the loan portfolio’s 109 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) current composition. As noted below in ‘‘Allowance for Loan and Lease Losses—Change in Methodology,’’ we changed our methodology for calculating the ALLL in the second quarter of 2018. See that section for details regarding this change. The quantitative estimation of the allowance for credit losses at December 31, 2018 considered actual historical loan and lease charge-off experience over a 40-quarter look-back period starting with the first quarter of 2009. 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, 2017 considered actual historical loan and lease charge-off experience over a 31-quarter look-back period starting with the first quarter of 2010. The increase in the historical look-back period to a 40-quarter look-back period at December 31, 2018 from 31 quarters at December 31, 2017 was done as part of our ALLL methodology change in the second quarter of 2018 and allows the look-back period to capture sufficient loss observations that is relevant to the current portfolio. In a good economic cycle with less frequent loss events, management believes a longer look-back period is more appropriate to reflect the level of incurred losses over an entire economic cycle. 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 collateral 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 loan commitments using the same loss factors as used for the allowance for loan and lease losses. The reserve for unfunded loan commitments is computed using expected future usage of the unfunded commitments based on historical usage of unfunded commitments for the various loan types. 110 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 directly correlated to the credit risk ratings of our loans. 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 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 rated as ‘‘pass’’ are not adversely classified and collection and repayment in full are expected. (cid:129) Special Mention: Loans and leases rated 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 rated 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 rated as ‘‘doubtful’’ have all the weaknesses of those rated 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 6. Loans and Leases. Management believes the allowance for credit losses is appropriate for the known and inherent risks in our 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 and lease losses—change in methodology. The ALLL represents management’s estimate of probable credit losses inherent in the loan portfolio as of the balance sheet date. Our methodology to estimate the ALLL has three basic elements that include specific reserves for individually evaluated impaired loans, a quantitative general allowance for all other loans (including individually evaluated loans determined not to be impaired), and qualitative adjustments based on other factors which may be internal or external to the Company. During the second quarter of 2018, we changed our methodology used to estimate the quantitative general allowance due to the growth and increased complexity of the loan portfolio. 111 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) The new ALLL methodology included three primary changes: the quantitative component now employs a PD/LGD methodology; the loan segmentation groups our loan portfolio into 21 loan pools with similar risk characteristics (as opposed to 34 loan pools used under the previous methodology); and the historical range of loan performance history, or look-back period, was lengthened by one year to ten years. The new PD/LGD methodology estimates the likelihood of loans defaulting based on the historical degree that similar loans defaulted, and it estimates the degree of credit loss based on the historical average degree of loss experienced for these similar loans. The reduced number of loan pools provides greater statistical validity by having more default and loss histories within each pool for the quantitative general allowance estimation. The look-back period was extended to capture loan performance back to January 1, 2009, one year longer than under the historical loss migration methodology. Extending this look-back period includes more historical loan performance information. The loss emergence period was unchanged as we continue to use seven quarters. The methodology to estimate specific reserves for individually evaluated impaired loans did not change. The methodology to derive qualitative adjustments based on other internal or external factors was updated to align with the new PD/LGD methodology being applied to estimate the quantitative general allowance for unimpaired loans. As a result, the composition of the ALLL changed as the quantitative component increased and the qualitative component decreased as the new quantitative methodology now encompasses more information, such as the longer look-back period, that previously required a qualitative adjustment as part of determining the total ALLL estimate. These changes in the ALLL methodology did not result in material changes to management’s overall ALLL estimate at June 30, 2018. (i) 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’’ in the consolidated statements of earnings 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 30 years. Leasehold improvements are amortized over their estimated useful lives, or the life of the lease, whichever is shorter. (j) 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 and lease losses. Any subsequent write-downs are charged to ‘‘Noninterest expense’’ in the consolidated statements of earnings 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 included in ‘‘Noninterest expense.’’ 112 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) (k) Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in earnings in the period that includes the enactment date. Any interest or penalties assessed by the taxing authorities is classified in the financial statements as income tax expense. Deferred tax assets 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 not 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. (l) 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 instead are tested for impairment at least annually unless certain events occur or circumstances change. Goodwill represents the excess of the purchase price over the fair value of the net assets and other identifiable intangible assets acquired. We test for goodwill impairment annually or earlier if events or changes in circumstances indicate goodwill might possibly be impaired. 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 statements of earnings. Intangible assets with estimable useful lives are amortized over such useful lives to their estimated residual values. 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 113 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) amount would be recognized as a charge to ‘‘Noninterest expense’’ in the consolidated statements of earnings. (m) 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. Forfeitures of stock-based awards are recognized when they occur. 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. If it is determined that attainment of a financial measure higher than target is probable, the amortization will increase 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 may ultimately vest. 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 are paid on unvested TRSAs and are charged to equity and the related tax impact is recorded to income tax expense. Dividends paid on forfeited TRSAs 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 shares to be received by the award holder. (n) Derivative Instruments Our derivative contracts primarily manage the foreign currency risk associated with certain assets and liabilities. As of December 31, 2018, 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 derivatives provide for a fixed exchange rate which has the effect of reducing or eliminating changes to anticipated cash flows to be received on assets and liabilities 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 ‘‘Noninterest income—other’’ in the consolidated statements of earnings. At December 31, 2018, our derivative contracts had a notional value of $80.5 million. 114 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Derivative instruments expose us to credit risk in the event of nonperformance by counterparties. 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. (o) Equity Investments Investments in common or preferred stock that are not publicly traded and certain investments in limited partnerships are considered equity investments that do not have a readily determinable fair value. If we have the ability to significantly influence the operating and financial policies of the investee, the investment is 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 equity investment carrying values are included in other assets and our share of earnings and losses in equity method investees is included in ‘‘Noninterest income—other’’ on the consolidated statements of earnings. Prior to January 1, 2018, if we did not have significant influence over the investee, the cost method was used to account for the equity interest. Effective January 1, 2018 with the adoption of ASU 2016-01, our accounting treatment for equity investments differs for those with and without readily determinable fair values. Equity investments with readily determinable fair values are recorded at fair value with changes in fair value recorded in ‘‘Noninterest income—other.’’ For equity investments without readily determinable fair values we have elected the ‘‘measurement alternative,’’ and therefore carry these investments at cost, less impairment (if any), plus or minus changes in observable prices. On a quarterly basis, we review our equity investments without readily determinable fair values for impairment. We consider a number of qualitative factors such as whether there is a significant deterioration in earnings performance, credit rating, asset quality, or business prospects of the investee in determining if impairment exists. If the investment is considered impaired, an impairment loss equal to the amount by which the carrying value exceeds its fair value is recorded through a charge to earnings. The impairment loss may be reversed in a subsequent period if there are observable transactions for the identical or similar investment of the same issuer at a higher amount than the carrying amount that was established when the impairment was recognized. Impairment as well as upward or downward adjustments resulting from observable price changes in orderly transactions for identical or similar investments are included in ‘‘Noninterest income—other.’’ Realized gains or losses resulting from the sale of equity investments are calculated using the specific identification method and are included in ‘‘Noninterest income—other.’’ (p) Comprehensive Income Comprehensive income consists of net earnings and net unrealized gains (losses) on debt securities available-for-sale, net, and is presented in the consolidated statements of comprehensive income. 115 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) (q) Earnings Per Share In accordance with ASC Topic 260, ‘‘Earnings Per Share,’’ all outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends are considered participating securities and are included in the two-class method of determining basic and diluted earnings per share. All of our unvested restricted stock participates with our common stockholders in dividends. Accordingly, earnings allocated to unvested restricted stock are deducted from net earnings to determine that amount of earnings available to common stockholders. In the two-class method, the amount of our earnings available to common stockholders is divided by the weighted average shares outstanding, excluding any unvested restricted stock, for both the basic and diluted earnings per share. (r) Business Combinations Business combinations are accounted for under the acquisition method of accounting in accordance with ASC Topic 805, ‘‘Business Combinations.’’ Under the acquisition method, the acquiring entity in a business combination recognizes 100 percent of the acquired assets and assumed liabilities, regardless of the percentage owned, at their estimated fair values as of the date of acquisition. Any excess of the purchase price over the fair value of net assets and other identifiable intangible assets acquired is recorded as goodwill. To the extent the fair value of net assets acquired, including other identifiable assets, exceeds the purchase price, a bargain purchase gain is recognized. Assets acquired and liabilities assumed from contingencies must also be recognized at fair value, if the fair value can be determined during the measurement period. Results of operations of an acquired business are included in the statement of earnings from the date of acquisition. Acquisition-related costs, including conversion and restructuring charges, are expensed as incurred. (s) 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, 2018 and since December 31, 2015, we have 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, 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. 116 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) (t) Recently Issued Accounting Standards 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, and is effective for annual and interim periods in fiscal years beginning after December 15, 2018. There have been further amendments issued in 2018, including practical expedients, with the issuance of ASU 2018-01, ‘‘Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842,’’ ASU 2018-10, ‘‘Codification Improvements to Topic 842, Leases,’’ ASU 2018-11, ‘‘Leases (Topic 842): Targeted Improvements,’’ and ASU 2018-20, ‘‘Leases (Topic 842): Narrow-Scope Improvements for Lessors.’’ The Company will adopt the standard effective January 1, 2019 and apply the guidance to all leases within the scope of Topic 842 as of that date using the optional transition method to not adjust comparative period financial information. We have elected the following practical expedients: (1) as a lessee we will not separate lease and non-lease components when determining the amount of right of use assets; (2) we have elected the package of transition practical expedients including (a) not to reassess whether any expired or existing contracts are or contains leases, (b) maintain existing lease classification, and (c) we will not reassess initial direct costs for leases existing at January 1, 2019; (3) we will not record short term leases on the balance sheet; and (4) we have elected to present sales tax on a ‘‘net’’ basis for those transactions in which we are the lessor. The primary impact of the new standard to the Company relates to leased branches and office space which are accounted for as operating leases. Adoption of the new standard on January 1, 2019 resulted in the recording of lease right-of-use assets of approximately $131 million and lease right-of-use liabilities of approximately $146 million with the difference due to the offset of previously accrued deferred rent and vacant space accruals based on the lease population as of January 1, 2019. The standard will not materially impact our consolidated statements of earnings and has no impact on cash flows. Effective January 1, 2019, the Company implemented: (1) a new lease accounting and administrative system, (2) new processes and procedures, and (3) new internal controls. As a lessor, we expect to recognize more sales-type leases that are currently accounted for as direct financing leases. The change in the definition of initial direct costs to include only incremental direct costs will also result in an acceleration of certain operating costs. Given the limited changes to lessor accounting, we have determined that the adoption of the new standard will not have a material impact on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, ‘‘Measurement of Credit Losses on Financial Instruments,’’ which significantly changes the way entities recognize credit losses and impairment of financial assets recorded at amortized cost. Currently, the credit loss and impairment model for loans and leases 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 new current expected credit loss (‘‘CECL’’) model, the standard requires immediate recognition of estimated credit losses expected to occur over the remaining life of the asset. The forward-looking concept of CECL to estimate future credit losses will broaden the range of data to consider including past and current events and conditions along with reasonable and supportable forecasts that may affect expected collectability. ASU 2016-13 also amends the accounting for credit 117 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The standard will add new disclosure requirements and impact the Company’s processes and internal controls over financial reporting. The issuance of ASU 2018-19, ‘‘Codification Improvements to Topic 326, Financial Instruments—Credit Losses,’’ in November 2018 clarified that receivables arising from operating leases are not within the scope of the new credit losses standard. The FASB has also issued an exposure draft in November 2018 which contains matters related to the CECL guidance and the FASB’s Transition Resource Group continues to field questions on issues requiring further interpretation and guidance. We expect discussions on these and other interpretation matters to continue throughout 2019 and beyond the effective date of January 1, 2020. The Company has established a multidisciplinary project team and implementation plan, selected a software solution, reached preliminary accounting decisions on various matters, developed a conceptual framework, developed initial regression models for the reasonable and supportable forecast period, and is engaged in the implementation phase of the project. The Company, with the assistance of a third party adviser, continues to work on: (1) developing and documenting a new expected loss model with supportable assumptions, (2) addressing data and reporting requirements, (3) assessing updates to accounting policies, and (4) documenting new processes and controls. The Company expects to begin parallel calculations, testing, and sensitivity analysis on its initial modeling assumptions and results in the first quarter of 2019. ASU 2016-13 is effective for interim and annual periods in fiscal years beginning after December 15, 2019, with earlier adoption permitted. The Company plans to adopt this standard on January 1, 2020. Entities are required to use a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted (modified-retrospective approach). A prospective transition approach is required for available-for-sale debt securities for which an other-than-temporary impairment had been recognized before the adoption date. The new standard will be significant to the policies, processes, and methodology used to determine credit losses; however, the Company has not yet determined the quantitative effect on its consolidated financial position and 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. While early adoption is permitted, the Company has no intention of doing so at this time and does not expect the adoption to have a material impact on its consolidated financial position or results of operations. 118 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) In August 2018, the FASB issued ASU 2018-13, ‘‘Fair Value Measurement (Topic 820): Disclosure Framework—Changes to Disclosure Requirements for Fair Value Measurements,’’ which changes the fair value measurement disclosure requirements of ASC 820. ASU 2018-13 must be applied prospectively and is effective for the Company on January 1, 2020. Early adoption is permitted. The Company will early adopt any removed or modified disclosures effective January 1, 2019 but will defer adoption of the additional disclosures until the effective date as permitted in the transition guidance in ASU 2018-13. The Company does not expect ASU 2018-13 to have a material impact on its consolidated financial position or results of operations. In August 2018, the FASB issued ASU 2018-15, ‘‘Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (a consensus of the FASB Emerging Issues Task Force),’’ which aligns the requirements for capitalizing implementation costs in a cloud computing arrangement service contract with the requirements for capitalizing implementation costs incurred for an internal-use software license. The new guidance also prescribes the balance sheet, income statement, and cash flow classification of the capitalized implementation costs and related amortization expense, and requires additional quantitative and qualitative disclosures. ASU 2018-15 is effective for the Company on January 1, 2020 and the Company has the option to adopt the new standard either prospectively to eligible costs incurred on or after the date this guidance is first applied or retrospectively. Early adoption is permitted. The Company will early adopt this standard prospectively effective January 1, 2019, and we have determined that the adoption of ASU 2018-15 will not have a material impact on its consolidated financial position or results of operations. NOTE 2. 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, 2018 and 2017 were $77.0 million and $77.6 million. As of December 31, 2018 and 2017, we pledged cash collateral for our derivative contracts of $2.6 million and $2.7 million. 119 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 3.

ACQUISITIONS (Continued) CUB Acquisition We acquired CUB on October 20, 2017. As part of the acquisition, CU Bank, a wholly-owned subsidiary of CUB, was merged with and into PacWest’s wholly-owned banking subsidiary, Pacific Western Bank. We completed the acquisition to, among other things, enhance our Southern California community bank franchise by adding a $2.1 billion loan portfolio and $2.7 billion of core deposits. The CUB acquisition has been accounted for under the acquisition method of accounting. We acquired $3.5 billion of assets and assumed $2.8 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 $374.7 million. All of the recognized goodwill is non-deductible for tax purposes. NOTE 4.

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 estimated aggregate amortization expense related to our current intangible assets for each of the next five years is $18.7 million for 2019, $14.6 million for 2020, $10.8 million for 2021, $7.5 million for 2022 and $3.8 million for 2023. 121 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 4.

INVESTMENT SECURITIES (Continued) See Note 13. Fair Value Measurements for information on fair value measurements and methodology. As of December 31, 2018, securities available-for-sale with a fair value of $458.1 million were pledged as collateral for borrowings, public deposits and other purposes as required by various statutes and agreements. Realized Gains and Losses on Securities Available-for-Sale Realized gains or losses in the consolidated statements of earnings resulting from the sale of securities are calculated using the specific identification method and included in gain (loss) on sale of securities. During the year ended December 31, 2018, we sold $563.6 million of securities available-for-sale for a gross realized gain of $9.2 million and a gross realized loss of $1.0 million. During the year ended December 31, 2017, we sold $355.4 million of securities available-for-sale for a gross realized gain of $3.3 million and a gross realized loss of $3.8 million. We also sold $404.5 million of the $447.0 million of securities obtained in the CUB acquisition for no gain or loss as they were marked to fair value at the time of acquisition. 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.

The reclassification was applied prospectively without prior period amounts being restated. We reviewed the securities that were in an unrealized loss position at December 31, 2018 and 2017, and concluded their unrealized losses were a result of the level of market interest rates relative to the types of securities and pricing changes caused by shifting supply and demand dynamics and not a result of downgraded credit ratings or other indicators of deterioration of the underlying issuers’ ability to repay. Accordingly, we determined the securities were temporarily impaired and we did not recognize such impairment in the 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.

INVESTMENT SECURITIES (Continued) FHLB Stock In connection with outstanding FHLB advances, the Bank owned FHLB stock carried at cost of $32.1 million and $20.8 million at December 31, 2018 and 2017. At December 31, 2018 and 2017, the Bank was required to own FHLB stock at least equal to 2.7% of outstanding FHLB advances. During the year ended December 31, 2018, FHLB stock increased by $11.3 million due to $55.6 million in purchases, offset partially by $44.3 million in redemptions. We evaluated the carrying value of our FHLB stock investment at December 31, 2018, 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 Our 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 included in the carrying amount of loans that are sold. Prior to January 1, 2018, our loan and lease portfolio consisted of Non-PCI loans and leases and PCI loans. Non-PCI loans and leases were those we originated or those we acquired that were not credit impaired at the dates of acquisition. PCI loans were purchased loans for which there was, at the acquisition date, evidence of credit deterioration since their origination and for which it was probable that collection of all contractually required payments was unlikely. As our gross PCI loan portfolio represented less than 0.4% of total loans as of the end of 2017, beginning in 2018 the PCI loans were accounted for as Non-PCI loans. Accordingly, in the credit quality tables below under ‘‘Loans and leases held for investment,’’ amounts related to 2018 are for total loans and leases, and amounts related to 2017 and 2016 are for Non-PCI loans and leases. 125 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 6. LOANS AND LEASES (Continued) Loans Held for Sale In the fourth quarter of 2017, we entered into an agreement to sell $1.5 billion of cash flow loans and exited our National Lending origination operations related to general, technology, and healthcare cash flow loans. As of December 31, 2017, $1.0 billion of the loans sold had settled, while $481.1 million were classified as held for sale. The loans held for sale at December 31, 2017 settled in the first quarter of 2018. In connection with the loan sale and transfer of loans to held for sale, we recognized $2.2 million in charge-offs during the fourth quarter of 2017 to record the loans at the lower of cost or fair value.

It is our policy to discontinue accruing interest when principal or interest payments are past due 90 days or more unless the loan is both well secured and in the process of collection or when, in the opinion of management, there is a reasonable doubt as to the collectability of a loan or lease in the normal course of business. Interest income on nonaccrual loans is recognized only to the extent cash is received and the principal balance of the loan is deemed collectable. The amount of interest income that would have been recorded on nonaccrual loans and leases at December 31, 2018 and 2017 had such loans and leases been current in accordance with their original terms was $9.3 million and $10.8 million for 2018 and 2017. 128 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 6.

The Company has purchased life insurance policies on certain employees and has also acquired life insurance policies through acquisitions. BOLI is recorded at the amount that can be realized under the insurance contract, which is the cash surrender value. The increase in the cash surrender value each period and the receipt of death benefit proceeds are recorded to ‘‘Noninterest income—other.’’ The Company makes various investments for CRA investment purposes including, but not limited to, CRA-related loan pool investments, CRA-related equity investments and investments in LIHTC partnerships. The loan pool and other CRA equity investments primarily consist of investments in partnerships which provide affordable housing and participations in loan pools which provide low-cost loans to low and moderate income applicants. The Company invests as a limited partner in LIHTC partnerships that operate qualified affordable housing projects and generate tax benefits for investors, including federal low income housing tax credits. The partnerships are deemed to be VIEs because they do not have sufficient equity investment at risk and are structured with non-substantive voting rights; however, we are not the primary beneficiary of the VIEs and do not consolidate them. We amortize the investment in proportion to the allocated tax benefits using the proportional amortization method of accounting and record such benefits net of investment amortization in income tax expense. The Company’s equity investments without readily determinable fair values include investments in privately held companies and limited partnerships as well as investments in entities from which we issued trust preferred securities. On January 1, 2018, we adopted ASU 2016-01 and ASU 2018-03 which changed the way we account for equity investments without readily determinable fair values previously accounted for using the cost method. Upon adoption, we have elected to measure our equity investments without readily determinable fair values using the measurement alternative. The Company reclassified $1.2 million of equity securities without readily determinable fair values previously included in securities available-for-sale to other assets on our condensed consolidated balance sheet in the first 140 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 9. OTHER ASSETS (Continued) quarter of 2018. The reclassification was applied prospectively without prior period amounts being restated. Carrying values of these investments are adjusted to fair value upon observable transactions for identical or similar investments of the same issuer. During the year ended December 31, 2018, we sold a portion of one of our equity investments without a readily determinable fair value for an amount in excess of its basis, and consequently increased by $286,000 the remaining carrying value of this investment at December 31, 2018. During the year ended December 31, 2018, we recorded impairment of $278,000 in the aggregate on five of our CRA equity investments without readily determinable fair values. Beginning January 1, 2018, unrealized and realized gains and losses on equity investments without readily determinable fair values are recorded in ‘‘Noninterest income—other.’’ The Company’s equity investments with readily determinable fair values include investments in public companies, often from the exercise of warrants, and publicly-traded mutual funds. The Company reclassified $5.9 million of equity securities with readily determinable fair values previously included in securities available-for-sale to other assets on the condensed consolidated balance sheet in the first quarter of 2018. The reclassification was applied prospectively without prior period amounts being restated. Beginning January 1, 2018, unrealized and realized gains and losses on equity investments with readily determinable fair values are recorded in ‘‘Noninterest income—other.’’ NOTE 10.

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.

These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets. The contract or notional amounts of those instruments reflect the extent of involvement that the Company has in particular classes of financial instruments. Commitments to extend credit are contractual agreements to lend to our customers when customers are in compliance with their contractual credit agreements and when customers have contractual availability to borrow under such agreements. 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 some of our lending arrangements and property lease obligations. Most guarantees expire within one year from the date of issuance. If a borrower defaults on its commitments subject to any letter of credit issued under these arrangements, we would be required to meet the borrower’s financial obligation but would seek repayment of that financial obligation from the borrower. In some cases, borrowers have pledged cash and investment securities as collateral with us under these arrangements. 144 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 small business investment companies that call for capital contributions up to an amount specified in the partnership agreements. As of December 31, 2018 and 2017, we had commitments to contribute capital to these entities totaling $102.0 million and $62.6 million. We also had commitments to contribute up to an additional $50,000 and $2.5 million to private equity funds at December 31, 2018 and 2017. 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, and taking into consideration insurance which may be applicable, would not have a material adverse effect on the Company’s financial statements or operations. NOTE 13. FAIR VALUE MEASUREMENTS ASC Topic 820, ‘‘Fair Value Measurement,’’ defines fair value, establishes a framework for measuring fair value including a three-level valuation hierarchy, and expands disclosures about fair value measurements. Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date reflecting assumptions that a market participant would use when pricing an asset or liability. The hierarchy uses three levels of inputs to measure the fair value of assets and liabilities as follows: (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, corporate debt securities, SBA securities, and asset-backed securitizations. (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, CDI, and other long-lived assets. 145 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 13.

Additionally, certain financial instruments and all nonfinancial instruments are excluded from the applicable disclosure requirements. On January 1, 2018, we adopted ASU 2016-01 and ASU 2018-03 which requires the use of the exit price notion when measuring the fair values of financial instruments for disclosure purposes. Starting in the first quarter of 2018, we updated our methodology used to estimate the fair value for our loan portfolio to conform to the new requirements. 150 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 13.

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 5. Investment Securities for further information on unrealized gains and losses on securities available-for-sale. Fair value for securities categorized as Level 1, which are 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 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. 152 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 13. FAIR VALUE MEASUREMENTS (Continued) Our non-rated private label CMOs and non-rated private label asset-backed securities (collectively, ‘‘the Level 3 AFS 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 AFS 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 AFS 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. Loans and leases. As 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 characteristics. Loans are segregated by type and further segmented into fixed and adjustable rate interest buckets by credit risk categories and by maturity dates. To determine the exit price of a loan or lease, the cash flows are estimated using a model which utilizes credit spreads and illiquidity premiums. The credit spread for a loan is determined by mapping loans’ credit risk ratings to an equivalent corporate bond rating. Once the corporate bond rating is assigned, the credit spread is determined using corporate credit curves for corporate bonds that have a similar corporate bond rating and remaining term as the loan being valued. Illiquidity premiums are assigned to individual loans in a similar manner as an illiquidity premium amount is determined for each corporate bond rating. The credit spread above the appropriate rate curve and the illiquidity premium are considered to arrive at the discount rate curve applied to loan cash flows. Impaired loans and leases. Nonaccrual loans and leases 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. Impaired loans and leases with outstanding balances over $250,000 are reviewed individually for the amount of impairment, if any. Impaired loans and leases with outstanding balances less than or equal to $250,000 may not be individually assessed for impairment but are assessed with reserves based on the average loss severity on historical impaired loans with similar risk characteristics. 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, 2018. 153 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 13. FAIR VALUE MEASUREMENTS (Continued) 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 loan and lease 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, 2018. The amounts shown as net losses include the impairment recognized during the year ended December 31, 2018, for the loan and lease balances shown. Loans held for sale. Loans held for sale are carried at the lower of cost or fair value, with fair value adjustments recorded on a nonrecurring basis. The loans held for sale at December 31, 2017 consisted of cash flow loans, and the fair value of these loans was based on sale agreements which we entered into during the fourth quarter of 2017. Loans held for sale which are under contract for sale are considered Level 2 in 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, 2018. When a current appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value as a result of known changes in the market or the collateral and there is no observable market price, such valuation inputs result in a fair value measurement that is categorized as a Level 3 measurement. To the extent a negotiated sales price or reduced listing price represents a significant discount to an observable market price, such valuation input would result in a fair value measurement that is also considered a Level 3 measurement. The OREO losses disclosed are write-downs based on either a recent appraisal obtained after foreclosure or an accepted purchase offer by an independent third party received after foreclosure. 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 underlying 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. 154 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 13. FAIR VALUE MEASUREMENTS (Continued) Equity investments with readily determinable fair values. Our equity investments with readily determinable fair values include investments in public companies and publicly-traded mutual funds. Equity investments with readily determinable fair values are recorded at fair value with changes in fair value recorded in ‘‘Noninterest income—other.’’ During the first quarter of 2018, the Company reclassified $5.9 million of equity securities with readily determinable fair values previously included in securities available-for-sale to other assets on our consolidated balance sheet. The reclassification was applied prospectively without prior period amounts being restated. Fair value measurements related to these investments are typically classified within Level 1 of the fair value hierarchy. Deposits. Deposits are carried at historical cost. The fair values of deposits with no stated maturity, such as core deposits (defined as noninterest-bearing demand, interest checking, money market, and savings accounts) and non-core non-maturity deposits, are 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 counter-party credit risk in valuing our derivatives. We typically classify our foreign exchange derivatives in Level 2 of the fair value hierarchy. 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. 155 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 13. FAIR VALUE MEASUREMENTS (Continued) Limitations Fair value estimates are made at a specific point in time and are based on relevant market information and information about the financial instrument. These estimates do not reflect income taxes or any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a portion of the Company’s financial instruments, fair value estimates are based on what management believes to be conservative judgments regarding expected future cash flows, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimated fair values are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Since the fair values have been estimated as of December 31, 2018, the amounts that will actually be realized or paid at settlement or maturity of the instruments could be significantly different.

The amount of amortization of such investments reported in income tax expense under the proportional amortization method of accounting was $11.9 million for 2018 and $6.3 million for 2017. We have net operating loss carryforwards for state income tax purposes and federal tax credit carryforwards that can be utilized to offset future taxable income. 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, 2018, we had no federal net operating loss carryforwards and approximately $1.1 billion of unused state net operating loss carryforwards available to be applied against future taxable income. A majority of the state net operating loss carryforwards will expire in varying amounts beginning in 2019 through 2038. A portion of the state net operating loss carryforwards generated after December 31, 2017 will carry forward indefinitely due to the state conformity to the federal net operating loss carryforward provisions as modified by the TCJA. 157 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 14. INCOME TAXES (Continued) As of December 31, 2018, for federal tax purposes, we had capital loss carryforwards of $0.1 million. If not used, these carryforwards will fully expire in 2021. As of December 31, 2018, for federal tax purposes, we had foreign tax credit carryforwards of $5.2 million. The foreign tax credit carryforwards are available to offset federal taxes on future foreign source income. If not used, these carryforwards will fully expire in 2021.

INCOME TAXES (Continued) Based upon our taxpaying history and estimates of taxable income over the years in which the items giving rise to the deferred tax assets are deductible, management believes it is more likely than not the Company will realize the benefits of these deferred tax assets. The Company had net income taxes receivable of $38.9 million and $98.8 million at December 31, 2018 and December 31, 2017. As of December 31, 2018 and 2017, the Company had a valuation allowance of $78.4 million and $94.1 million against DTAs. Periodic reviews of the carrying amount of DTAs 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 the year ended December 31, 2018 was $15.7 million. Of this amount, $11.6 million consisted principally of adjustments to DTAs for tax attributes that expired in 2018. The DTAs 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 $11.6 million of deferred tax assets had no impact on the Company’s effective tax rate for the year ended December 31, 2018. The remaining $4.1 million reduction in the valuation allowance was primarily due to an increase in the amount of foreign tax credit and capital loss carryforwards that were determined to be more likely than not to be utilized prior to expiration.

INCOME TAXES (Continued) We recognize interest and penalties related to unrecognized tax benefits as a component of income tax expense. For the year ended December 31, 2018, we recognized $0.2 million in expense for interest expense and penalties. For the year ended December 31, 2017, we recognized $0.2 million in expense related to these items. 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. We had $0.8 million and $0.5 million accrued for the payment of interest and penalties as of December 31, 2018 and 2017. We file federal and state income tax returns with the Internal Revenue Service (‘‘IRS’’) and various state and local jurisdictions and generally remain subject to examinations by these tax jurisdictions for tax years 2011 through 2017. We are currently under examination by the IRS for tax years 2011 through 2012 and certain state jurisdictions for tax years 2012 through 2016. NOTE 15.

REVENUE FROM CONTRACTS WITH CUSTOMERS The Company adopted Topic 606 Revenue from Contracts with Customers effective as of January 1, 2018 and has applied the guidance to all contracts within the scope of Topic 606 as of that date. Revenue from contracts with customers in the scope of Topic 606 is measured based on the consideration specified in the contract with a customer, and excludes amounts collected on behalf of third parties. The Company recognizes revenue from contracts with customers when it satisfies its performance obligations. The Company’s performance obligations are typically satisfied as services are rendered and payment is generally collected at the time services are rendered, or on a monthly, quarterly or annual basis. The Company had no material unsatisfied performance obligations as of December 31, 2018. In certain cases, other parties are involved with providing products and services to our customers. If the Company is a principal in the transaction (providing goods or services itself), revenues are reported based on the gross consideration received from the customer and any related expenses are reported gross in noninterest expense. If the Company is an agent in the transaction (arranging for another party to provide goods or services), the Company reports its net fee or commission retained as revenue. Rebates, waivers, and reversals are recorded as a reduction of revenue either when the revenue is recognized by the Company or at the time the rebate, waiver, or reversal is earned by the customer. The Company has elected the following practical expedients: (1) we do not disclose information about remaining performance obligations that have original expected durations of one year or less; and (2) we do not adjust the consideration from customers for the effects of a significant financing component if at contract inception the period between when the Company transfers the goods or services and when the customer pays for that good or service will be one year or less. Nature of Goods and Services Substantially all of the Company’s revenue, such as interest income on loans, investment securities, and interest-earning deposits in financial institutions, is specifically out-of-scope of Topic 606. For the revenue that is in-scope, the following is a description of principal activities, separated by the timing of revenue recognition, from which the Company generates its revenue from contracts with customers: (cid:129) Revenue earned at a point in time. Examples of revenue earned at a point in time are ATM transaction fees, wire transfer fees, NSF fees, and credit and debit card interchange fees. Revenue is generally derived from transactional information accumulated by our systems and is recognized as revenue immediately as the transactions occur or upon providing the service to complete the customer’s transaction. The Company is the principal in each of these contracts with the exception of credit and debit card interchange fees, in which case the Company is acting as the agent and records revenue net of expenses paid to the principal. (cid:129) Revenue earned over time. The Company earns certain revenue from contracts with customers monthly. Examples of this type of revenue are deposit account service fees, investment management fees, merchant referral services, MasterCard marketing incentives and safe deposit box fees. Account service charges, management fees and referral fees are recognized on a monthly basis while any transaction-based revenue is recorded as the activity occurs. Revenue is primarily based on the number and type of transactions and is generally derived from transactional information accumulated by our systems. Revenue is recorded in the same period as the related transactions occur or services are rendered to the customer. 161 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 16.

The change in contract liabilities for the year ended December 31, 2018 due to revenue recognized that was included in the contract liability balance at the beginning of the year was $131,000. NOTE 17. STOCK-BASED COMPENSATION The Company’s 2017 Stock Incentive Plan, or the 2017 Plan, permits stock-based compensation awards to officers, directors, key employees, and consultants. The 2017 Plan authorized grants of stock- based compensation instruments to issue up to 4,000,000 shares of Company common stock. As of December 31, 2018, there were 3,165,020 shares available for grant under the 2017 Plan. Though frozen for new issuances, certain awards issued under the 2003 Stock Incentive Plan, or the 2003 Plan, remain outstanding. Restricted Stock Restricted stock amortization totaled $29.1 million, $24.9 million, and $22.7 million for the years ended December 31, 2018, 2017, and 2016. 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 $7.7 million, $8.9 million, and $8.4 million for the years ended December 31, 2018, 2017, and 2016. The amount of unrecognized compensation expense related to all unvested TRSAs and PRSUs as of December 31, 2018 totaled $50.0 million. Such expense is expected to be recognized over a weighted average period of 1.3 years. The following table presents a summary of restricted stock transactions during the year ended December 31, 2018: TRSAs PRSUs Year Ended December 31, 2018 Unvested restricted stock, beginning of year . . . . . . . . .

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. TRSA grants are subject to ‘‘double-trigger’’ vesting, meaning that, in the event of a change in control of the Company, as defined in the Plans, and in the event an employee’s employment is terminated within 24 months after the change in control by the Company without Cause or by the 163 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 17. STOCK-BASED COMPENSATION (Continued) employee for Good Reason, as defined in the Plans, such awards will vest. 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 2018, 2017, and 2016 were $53.69, $50.08, and $36.05. The vesting date fair value of TRSAs that vested during 2018, 2017, and 2016 were $25.9 million, $24.9 million, and $14.4 million. Performance-Based Restricted Stock Units At December 31, 2018, there were 325,741 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 until they vest. PRSUs are granted and initially expensed based on a target number. The number of shares 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. If it is determined that attainment of a financial measure higher than target is probable, the amortization will increase 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 may ultimately vest. 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. Upon a change in control, each PRSU will (i) be deemed earned at the target level with respect to all open performance periods if the change in control occurs within six months after the grant date, and (ii) be deemed earned at the actual performance level as of the date of the change in control if a change in control occurs more than six months after the grant date, and in both cases, the PRSU will cease to be subject to any further performance conditions, but will be subject to time-based service vesting following the change in control in accordance with the original performance period. The weighted average grant date fair value per share of PRSUs granted during 2018, 2017, and 2016 was $57.52, $57.80 and $27.32. There were no PRSUs that vested during 2018, 2017, and 2016. NOTE 18. 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 $4.3 million, $4.0 million and $3.7 million for the years ended December 31, 2018, 2017, and 2016. 164 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 19. 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, 2018, 2017, and 2016, the Company purchased 181,642 treasury shares at a weighted average price of $50.37 per share, 188,870 treasury shares at a weighted average price of $50.17 per share, and 141,358 treasury shares at a weighted average price of $37.59 per share. Stock Repurchase Program The Stock Repurchase Program was initially authorized by PacWest’s Board of Directors on October 17, 2016, pursuant to which the Company could, until December 31, 2017, purchase shares of its common stock for an aggregate purchase price not to exceed $400 million. On November 15, 2017, PacWest’s Board of Directors amended the Stock Repurchase Program to reduce the authorized purchase amount to $150 million and extend the maturity date to December 31, 2018. On February 14, 2018, PacWest’s Board of Directors amended the Stock Repurchase Program to increase the authorized purchase amount to $350 million and extend the maturity date to February 28, 2019. 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 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. During the year ended December 31, 2018, the Company repurchased 5,849,234 shares for $306.4 million at a weighted average price of $52.38 per share. During the year ended December 31, 2017, the Company repurchased 2,081,227 shares for $99.7 million at a weighted average price of $47.89 per share. During the year ended December 31, 2016, the Company repurchased 652,835 shares for $27.9 million at a weighted average price of $42.78 per share. All shares repurchased under the Stock Repurchase Program were retired upon settlement. At December 31, 2018, the remaining amount that could be used to repurchase shares under the Stock Repurchase Program was $110.1 million. 165 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 20. 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 DGCL 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. The Bank 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. The 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 the three previous fiscal years less any dividend paid during such period. Dividends paid by the Bank during the previous three fiscal years exceeded the Bank’s net earnings during that same period by $28.5 million. During 2018, PacWest received $684.0 million in dividends from the Bank. Since the Bank had an accumulated deficit of $643.9 million at December 31, 2018, 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. 166 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 20. DIVIDEND AVAILABILITY AND REGULATORY MATTERS (Continued) 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. 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, 2018, such disallowed amounts were $489,000 for the Company and $39,000 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 6.5%, and a minimum leverage ratio of 5.0%. As of December 31, 2018, 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, 2018, 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, 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, 2018, the Company and Bank were in compliance with the capital conservation buffer requirement. Effective January 1, 2019, the capital conservation buffer increased by 0.625% to its fully phased-in 2.5%, such that the common equity tier 1, tier 1 and total capital ratio minimums inclusive of the capital conservation buffer were 7.0%, 8.5%, and 10.5%. 167 PACWEST BANCORP AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) NOTE 20.
