You should not place undue reliance on these statements as they involve risks, uncertainties and contingencies, many of which are beyond our control, which may cause actual results, performance, or achievements to differ materially from those expressed in them. Actual results could differ materially from those anticipated in such forward-looking statements as a result of risks and uncertainties more fully described under "Item 1A. Risk Factors." Factors that might cause such differences include, but are not limited to:

•the COVID-19 pandemic is adversely affecting the Company, its employees, customers and third-party service providers, and the ultimate extent of the impacts of the pandemic and related government stimulus programs on its business, financial position, results of operations, liquidity and prospects is uncertain. Continued deterioration in general business and economic conditions could adversely affect the Company’s revenues and the values of its assets and liabilities, lead to a tightening of credit and increase stock price volatility;

•our ability to complete future acquisitions, and to successfully integrate such acquired entities or achieve expected benefits, synergies and/or operating efficiencies within expected time frames or at all;

•our ability to compete effectively against other financial service providers in our markets;

•the impact of changes in interest rates or levels of market activity, especially on the fair value of our loan and investment portfolios;

•deterioration, weaker than expected improvement, or other changes in the state of the economy or the markets in which we conduct business (including the levels of IPOs and mergers and acquisitions), which may affect the ability of borrowers to repay their loans and the value of real property or other property held as collateral for such loans;

•changes in credit quality, including the magnitude of individual loan losses, and the effect of credit quality and the CECL accounting standard on our provision for credit losses and allowance for credit losses;

•our ability to attract deposits and other sources of funding or liquidity;

•the need to retain capital for strategic or regulatory reasons;

•compression of the net interest margin due to changes in the interest rate environment, forward yield curves, loan products offered, spreads on newly originated loans and leases, changes in our asset or liability mix, and/or changes to the cost of deposits and borrowings;

•uncertainty regarding the future of LIBOR and the transition away from LIBOR toward new reference rates by the end of 2021;

•reduced demand for our services due to strategic or regulatory reasons or reduced demand for our products due to legislative changes such as new rent control laws;

•our ability to successfully execute on initiatives relating to enhancements of our technology infrastructure, including client-facing systems and applications;

•legislative or regulatory requirements or changes, including an increase of capital requirements, and increased political and regulatory uncertainty;

•the impact on our reputation and business from our interactions with business partners, counterparties, service providers and other third parties;

•higher than anticipated increases in operating expenses;

•lower than expected dividends paid from the Bank to the holding company;

•the amount and exact timing of any common stock repurchases will depend upon market conditions and other factors;

3

•a deterioration in the overall macroeconomic conditions or the state of the banking industry that could warrant further analysis of the carrying value of goodwill and could result in an adjustment to its carrying value resulting in a non-cash charge;

•the effectiveness of our risk management framework and quantitative models;

•the costs and effects of legal, compliance, and regulatory actions, changes and developments, including the impact of adverse judgments or settlements in litigation, the initiation and resolution of regulatory or other governmental inquiries or investigations, and/or the results of regulatory examinations or reviews;

•the impact of changes made to tax laws or regulations affecting our business, including the disallowance of tax benefits by tax authorities and/or changes in tax filing jurisdictions or entity classifications; and

•our success at managing risks involved in the foregoing items and all other risk factors described in our audited consolidated financial statements, and other risk factors described in this Form 10-K and other documents filed or furnished by PacWest with the SEC.

ITEM 1. 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 70 full-service branches located in California, one branch located in Durham, North Carolina, one branch located in Denver, Colorado, and numerous loan production offices across the country. The Bank provides community banking products including lending and comprehensive deposit and treasury management services to small and medium-sized businesses conducted primarily through our California-based branch offices and Denver, Colorado branch office. The Bank offers national lending products including asset-based, equipment, and real estate loans and treasury management services to established middle-market businesses on a national basis. The Bank also offers venture banking products including a comprehensive suite of financial services focused on entrepreneurial and venture-backed businesses and their venture capital and private equity investors, with offices located in key innovative hubs across the United States. In addition, we provide investment advisory and asset management services to select clients through Pacific Western Asset Management Inc., a wholly-owned subsidiary of the Bank and an 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 30 acquisitions since 2000, including the Civic acquisition on February 1, 2021, which have contributed to our growth and expanded our market presence throughout the United States. For more information regarding the Civic acquisition, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Recent Events.”

As of December 31, 2020, the Company had total assets of $29.5 billion, total loans and leases, net of deferred fees, of $19.1 billion, total deposits of $24.9 billion, and stockholders’ equity of $3.6 billion.

Our Business Strategy

Our business strategy is to operate a client-focused, well-capitalized and profitable nationwide bank dedicated to providing personal service to our business and individual customers. 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 venture capital and private equity firms nationwide, many of which are also our clients and/or may invest in our clients.

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 providing access to an array of our products and services, including attracting deposits from and offering cash management solutions to our loan and lease customers. We competitively price our deposit products to meet the needs of our customers with a view to maximizing our share of each customer's financial services business and prudently managing our cost of funds.

6

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 to 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 30 acquisitions since 2000, including the Civic acquisition on February 1, 2021. 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. We also serve our customers through a wide range of non-branch channels, including online, 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, 2020, we had ATMs at 54 of our branches located in California and one ATM at our branch in Denver, Colorado. We are a member 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 online banking services.

At December 31, 2020, our total deposits consisted of $22.3 billion in core deposits, $1.5 billion in time deposits, and $1.1 billion in non-core non-maturity deposits. Core deposits represented 89% of total deposits at December 31, 2020, and were comprised of $9.2 billion in noninterest-bearing deposits, $6.5 billion in money market accounts, $6.0 billion in interest-bearing checking accounts, and $562.8 million in savings accounts. Our deposit base is also diversified by client type. As of December 31, 2020, no individual depositor represented more than 4.3% of our total deposits, and our top ten depositors represented 13.4% 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 actively compete for deposits and emphasize solicitation of noninterest-bearing deposits. We seek to provide a higher level of personal service than our larger competitors, many of whom have more assets, capital and resources than we do and who may be able to conduct more intensive and broader based promotional efforts to reach potential customers. Our cost of funds fluctuates with market interest rates and may be affected by higher rates being offered by other financial institutions. In certain interest rate environments, additional significant competition for deposits may be expected to arise from corporate and government debt securities and money market mutual funds. Competition for deposits is also affected by the ease with which customers can transfer deposits from one institution to another.

Client Investment Funds

In addition to deposit products, we also offer select clients non-depository cash investment options through PWAM, our SEC registered investment adviser subsidiary, and third-party money market sweep products. PWAM provides customized investment advisory and asset management solutions. At December 31, 2020, total off-balance sheet client investment funds were $1.3 billion, of which $1.0 billion was managed by PWAM. At December 31, 2019, total off-balance sheet client investment funds were $1.5 billion, of which $1.2 billion was managed by PWAM.

Lending Activities

At December 31, 2020 and 2019, total loans and leases held for investment, net of deferred fees, were $19.1 billion and $18.8 billion. 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 portfolio is diverse and includes various asset-secured loans, equipment-secured loans and leases, venture capital loans to support venture capital firms’ operations and the operations of entrepreneurial and venture-backed companies, loans to finance life insurance premiums, and secured business loans originated through our Community Banking group.

In October 2019, we ceased originating new security monitoring loans and healthcare real estate loans in our National Lending group.

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 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, 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, 2020 and 2019, we had SNC loans held for investment to 25 borrowers that totaled $579 million and to 28 borrowers that totaled $755 million. At December 31, 2020 and 2019, SNC loans held for investment comprised 3.0% and 4.0% of total loans and leases held for investment, net of deferred fees.

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.

Our real estate secured loans include the following specific lending products:

•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, industrial properties, and retail properties. 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 first deed of trust mortgage loans on owner occupied commercial real estate which are 50% loan-to-value at origination where a second deed of trust is also provided by a non-profit certified development company. The SBA 7(a) and 504 mortgage loans repay on a twenty-five year amortization schedule.

8

•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 multi-family and other for-rent, non-owner occupied residential properties. Multi-family properties comprise the majority of our income producing and other residential real estate loans. Other types of properties securing these loans include for-rent and owner-occupied single-family properties and mobile home parks. 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 either repay on a 30-year amortization schedule or may have an initial interest-only period (up to two years) and then repay on a 30-year amortization schedule. We do not typically originate owner-occupied single-family mortgage loans but we do have a small portfolio of owner-occupied single-family mortgage loans stemming primarily from banks that we acquired.

•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, hotel properties, and residential condominium properties. Construction loans typically finance from 40% to 70% of the cost to construct residential and commercial properties. The terms are generally one to three years with short-term, performance-based extension options. A very small component of this portfolio are single-family construction loans to qualifying home builders within our branch footprint and we have also purchased single-family renovation construction loans from Civic.

Our real estate portfolio is subject to certain risks including, but not limited to, the following:

•increased competition in pricing and loan structure;

•the economic conditions of the United States and in the markets where we lend;

•decreased demand or decreased values as a result of legislative changes such as new rent control laws;

•interest rate increases;

•decreased real estate values in the markets where we lend;

•the borrower's inability to repay our loan due to decreased cash flow or operating losses;

•the borrower’s inability to refinance or payoff our loan upon maturity;

•loss of our loan principal stemming from a collateral foreclosure; and

•various environmental risks, including natural disasters.

In addition to the points above, real estate construction loans are also subject to project-specific risks including, but not limited to, the following:

•construction costs being more than anticipated;

•construction taking longer than anticipated;

•failure by developers and contractors to meet project specifications or timelines;

•disagreement between contractors, subcontractors and developers;

•demand for completed projects being less than anticipated; and

•buyers of the completed projects not being able to secure permanent financing.

9

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. In October 2019, we ceased the origination of healthcare real estate loans in our National Lending group and expect real estate mortgage loans secured by healthcare properties to be a smaller portion of our real estate mortgage loans in the future.

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:

•requiring borrowers to invest and maintain a meaningful cash equity interest in the properties securing our loans;

•reviewing each loan request and renewal individually;

•using a credit committee approval process for the approval of each loan request (or aggregated credit exposures) over a certain dollar amount;

•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;

•considering market rental and occupancy rates relative to our underwritten or projected rental and occupancy rates;

•considering the experience of our borrowers and our borrowers’ abilities to operate and manage the properties securing our loans;

•evaluating the supply of comparable real estate and new supply under construction in the collateral's market area;

•obtaining independent third-party appraisals that are reviewed by our appraisal department;

•obtaining environmental risk assessments; and

•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:

•considering the experience of our borrowers and our borrowers’ abilities to manage the properties during construction and into the stabilization periods;

•obtaining project completion guaranties from our borrowers;

•including covenants in our construction loan agreements that require the borrowers to fund costs that exceed the initial construction budgets;

•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;

•conducting project site visits and using construction consultants who review the progress of the project; and

•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 specific SBA 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 portfolio is diverse and includes various asset-secured loans, equipment-secured loans and leases, venture capital loans to support venture capital firms’ operations and the operations of entrepreneurial and venture-backed companies, loans to finance life insurance premiums, 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:

•Lender finance. 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 lenders to small businesses, 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.

•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.

•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.

•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.

•Venture capital. These are loans directly to venture capital firms or loans to venture-backed companies. Equity fund loans are the loans made directly to venture capital firms, private equity funds, 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. 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.

•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.

11

•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. In October 2019, we decided to no longer originate new security monitoring loans. New technology is disrupting the security alarm business, causing increased customer acquisition costs and customer attrition and, thereby, adversely impacting business models and valuations.

•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.

•Paycheck Protection Program. Loans made under provisions of the CARES Act to assist eligible businesses fund their operating costs during the COVID-19 pandemic. Under this program, the SBA guaranties 100% of the amounts loaned. The loans have two or three year terms with a 1% loan coupon rate and origination fees that varied from 1% to 5% depending on the size of the loan. If the borrower meets certain requirements of the program, the loan can be forgiven by the SBA and the Bank would be paid off by the SBA prior to maturity.

Our portfolio of commercial loans and leases is subject to certain risks including, but not limited to, the following:

•the economic conditions of the United States;

•interest rate increases;

•deterioration of the value of the underlying collateral;

•increased competition in pricing and loan structure;

•denial of the SBA guaranty under the PPP loan program due to a deficiency in the manner a loan was originated or serviced, such as an issue with the eligibility of a borrower under the program;

•the deterioration of a borrower’s or guarantor’s financial capabilities; and

•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:

•considering the prospects for the borrower's industry and competition;

•considering our past experience with the borrower and with the collateral type;

•considering our current loan and lease portfolio concentration by loan type and collateral type;

•reviewing each loan request and renewal individually;

•maintaining and adhering to additional policies specific to the PPP loan program;

•using our credit committee approval process for the approval of each loan request (or aggregate credit exposure) over a certain dollar amount; and

•adhering to written loan underwriting policies and procedures including, among other factors, loan structures and covenants.

12

We actively manage real estate and commercial loans and seek to mitigate credit risk on most loans by using the following framework.

•monitoring the economic conditions in the regions or areas in which our borrowers are operating;

•measuring operating performance of our borrower or collateral and comparing it to our underwriting expectations;

•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;

•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;

•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

•subjecting loan modifications and loan renewal requests to underwriting and assessment standards similar to the underwriting and assessment standards applied before closing the loans.

Consumer Loans

Consumer loans are primarily purchased private student loans originated and serviced by third-parties and 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 internally originated 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:

•the economic conditions of the United States and the levels of unemployment;

•the amount of credit offered to consumers in the market;

•interest rate increases;

•consumer bankruptcy laws which allow consumers to discharge certain debts (excluding student loans);

•compliance with consumer lending regulations;

•additional regulations and oversight by the CFPB; and

•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. Each purchased pool of loans must meet thresholds we have established for weighted average credit scores, weighted average borrower annual income, and weighted average borrower monthly free cash flow. For all purchased student loans, we monitor the performance of the originator and the enforcement of our rights under the loan purchase agreement.

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, 2020 of $3.3 billion, collateralized by a blanket lien on $5.6 billion of qualifying loans. The Bank also had secured financing capacity with the FRBSF of $1.4 billion as of December 31, 2020 collateralized by liens on $1.9 billion of qualifying loans.

Information Technology Systems

We devote significant financial and management resources to maintain stable, reliable, efficient, secure and scalable information technology systems. Where possible, we utilize third-party software systems that are hosted and supported by nationally recognized vendors.  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 online, mobile, and telephone banking services to further improve the overall client experience.

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.

15

We maintain an information technology strategic plan. This plan defines the overall innovation and technology agenda and vision, tracks information technology and information security trends and priorities, and provides details on information technology initiatives over the next several years. Through our annual information technology budgeting process, we analyze our infrastructure for capacity planning, detail migration plans to replace aging hardware and software, and resource plan for internal and external information technology staffing needs against planned initiatives.

Protecting our systems to ensure the safety of customer information is critical to our business. We use multiple layers of protection to control access, detect unusual activity and reduce risk. We regularly conduct a variety of audits and vulnerability and penetration tests on our platforms, systems and applications and maintain comprehensive incident response plans to minimize potential risks, including cyber-attacks. 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.

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 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, underwriting standards, loan covenants, required guarantees, 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.

16

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 banking products in order to successfully compete in the marketplace.

Human Capital Management

Our business strategy is to operate a client-focused, well-capitalized and profitable nationwide bank dedicated to providing personal service to our business and individual customers. Our employees are our most important assets and they set the foundation for our ability to achieve our strategic objectives. We believe that we have a competitive advantage in the markets we serve because of our long-standing reputation for providing superior, relationship-based customer service. In order to continue to provide the expertise and customer service for which we are known, it is crucial that we continue to attract, retain and develop top talent. To facilitate talent attraction and retention, we strive to make the Bank a diverse, inclusive and safe workplace, with opportunities for our employees to grow and advance in their careers, supported by strong compensation, benefits and health and wellness programs.

Oversight and Management

We strive to attract, develop, and retain highly qualified employees for each role in the organization. Working under this principle, our Human Resources Department is tasked with managing employment-related matters, including recruiting and hiring, onboarding and training, compensation planning, performance management and professional development. Our Board of Directors and Board committees provide oversight on certain human capital matters, including our compensation and benefit programs. As noted in its charter, our Compensation, Nominating and Governance Committee is responsible for periodically reviewing employee compensation programs and initiatives to ensure they are competitive and aligned with our stockholders’ long-term interests, including incentives and benefits, as well as our succession planning and strategies. Our Audit Committee works closely with the Risk Committee to monitor current and emerging human capital management risks and to mitigate exposure to those risks.

Demographics

At December 31, 2020, we had approximately 1,700 full-time, part-time and temporary employees, the overwhelming majority of which were full-time employees. None of the Company’s employees are represented by a labor union or by collective bargaining agreements. During 2020, the number of employees decreased by approximately 6% due primarily to four branch closures. During 2020, our employee turnover rate was approximately 12.5%. The average tenure of our full-time employees is 8.2 years.

At December 31, 2020, the population of our workforce was as follows:

Gender	% of Total
Women	58%
Men	42%

Ethnicity	% of Total

Human Capital Management Objectives

Our key human capital management objectives are to attract, retain and develop the highest quality talent. To support these objectives, our human resources programs are designed to develop talent to prepare them for critical roles and leadership positions for the future, reward and support employees through competitive pay, benefit, and perquisite programs, enhance the Company’s culture through efforts aimed at making the workplace more engaging and inclusive, acquire talent and facilitate internal talent mobility to create a high-performing, diverse workforce, and evolve and invest in technology, tools and resources to enable employees to effectively and efficiently perform their responsibilities and achieve their full potential.

Some examples of key programs and initiatives that are focused to attract, develop and retain our workforce include:

Compensation and benefits. The philosophy and objectives underlying our compensation programs are to employ and retain talented employees to ensure we execute on our business goals, drive short- and long-term profitable growth of the Company and create long-term stockholder value. In allocating total compensation, we seek to provide competitive levels of fixed compensation (base salary) and, through annual and long-term incentives, provide for increased total compensation when performance objectives are exceeded and appropriately lower total compensation if performance objectives are not met. Specifically:

•We provide employee wages that are competitive and consistent with employee positions, skill levels, experience, knowledge and geographic location.

•We engage nationally recognized outside compensation and benefits consulting firms to independently evaluate the effectiveness of our compensation and benefit programs and to provide benchmarking against our peers within the industry.

•We align our executives’ long-term equity compensation with our stockholders’ interests by linking realizable pay with Company performance.

•Annual increases and incentive compensation are based on merit, which is communicated to employees at the time of hiring and documented through our talent management process as part of our annual review procedures and upon internal transfer and/or promotion.

•All full-time employees are eligible for health insurance (medical, dental & vision), paid and unpaid leaves, a 401k plan with Company matching and life and disability/accident coverage. We also offer a variety of voluntary benefits that allow employees to select the options that meet their personal and family needs, including health savings and flexible spending accounts, paid parental leave, public transportation reimbursement, employee assistance programs, personalized wellness programs and a tuition reimbursement program.

Health, Safety and Wellness. The health, safety and wellness of our employees is fundamentally connected to the success of our business. We provide our employees and their families with access to a variety of flexible, convenient and innovative health and wellness programs to help them improve or maintain their physical and mental well-being. The safety of our employees and customers is paramount. We strive to ensure that all employees feel safe in their respective work environment. In response to the COVID-19 pandemic, we implemented significant changes that we determined were in the best interest of our employees, as well as the communities in which we operate, and which comply with government regulations. This includes having the vast majority of our non-branch employees work from home, while implementing additional safety measures and paying special bonuses for employees continuing critical on-site work.

18

Talent Development. We believe that creating an environment which encourages continual learning and development is essential for us to maintain a high level of service and to achieve our goal to have every employee feel that they are a valued member of a successful company. Our employees receive continuing education courses that are relevant to the banking industry and their job function within the Company. We also offer a tuition reimbursement program for courses that are relevant to banking and/or the employee’s job functions. We will also pay the tuition for eligible employees to attend a three-year banking program offered by certain universities. The goal of “Talent Management @ PWB” is to aspire, attract, engage, develop, and reward the best people to meet ongoing future growth of the Company with a collaborative and innovative culture. Our talent management processes and resources consist of three areas that support the ongoing high performance of all employees: Goal Setting, Performance Management and Professional Development.

Diversity and Inclusion. We are committed to creating a culture of inclusion – where differences are both appreciated and respected. We take pride in providing equal employment opportunities and building a workplace culture where all employees feel supported and respected, and have equal access to career and development opportunities without regard to race, religion/creed, color, national origin, age, marital status, ancestry, sex, gender (including pregnancy, childbirth, breastfeeding or related medical conditions), gender identity/expression, sexual orientation, veteran status, physical or mental disability, medical condition, military status or any other characteristic protected by federal, state or local laws. To help accomplish this, we have a SVP, Diversity & Inclusion, who is supported by a Diversity and Inclusion Advisory Council made up of 21 employee representatives from throughout the Company to advance our diversity and inclusion initiatives. We strive to build teams and grow talent that reflects the diversity of the clients and communities we serve. Our practice is to hire an individual based on their skill and talent.

Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and “Item 7A.

Financial Statements and Supplementary Data.”

Supervision and Regulation

General

The Company and Bank are subject to extensive regulation under federal and state banking laws that establish a comprehensive framework for our operations. Such regulation is intended to, among other things, protect the interests of customers, including depositors, and the federal deposit insurance fund, as well as to minimize risk to the banking system as a whole. These regulations are not, however, generally charged with protecting the interests of our stockholders or 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, particularly in the current U.S. political environment, and in their application by regulatory agencies, cannot be predicted, and they may have a material effect on the business, operations, and results of the Company or the Bank.

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, which codified the FRB's long-standing "source-of-strength" doctrine, 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.

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 Note 21. 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 DFPI and the FDIC.

Our ability to pay dividends to our stockholders or to repurchase shares of our common stock is subject to the restrictions set forth in the DGCL. The DGCL provides that a corporation, unless otherwise restricted by its certificate of incorporation, may declare and pay dividends (or repurchase shares) out of its surplus or, if there is no surplus, out of net profits for the fiscal year in which the dividend is declared and/or for the preceding fiscal year, as long as the amount of capital of the corporation is not less than the aggregate amount of the capital represented by the issued and outstanding stock of all classes having a preference upon the distribution of assets. Surplus is defined as the excess of a corporation’s net assets (i.e., its total assets minus its total liabilities) over the capital associated with issuances of its common stock. Moreover, the DGCL permits a board of directors to reduce its capital and transfer such amount to its surplus. In determining the amount of surplus of a Delaware corporation, the assets of the corporation, including stock of subsidiaries owned by the corporation, must be valued at their fair market value as determined by the board of directors, regardless of their historical book value.

Our ability to pay cash dividends to our stockholders or to repurchase shares of our common stock may be limited by certain covenants contained in the indentures governing trust preferred securities issued by us or entities that we have acquired, and the debentures underlying the trust preferred securities. Generally the indentures provide that if an Event of Default (as defined in the indentures) has occurred and is continuing, or if we are in default with respect to any obligations under our guarantee agreement which covers payments of the obligations on the trust preferred securities, or if we give notice of any intention to defer payments of interest on the debentures underlying the trust preferred securities, then we may not, among other restrictions, declare or pay any dividends with respect to our common stock or repurchase shares of our common stock.

21

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 may be required in certain circumstances 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 DFPI 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 DFPI 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. The Bank had a net loss of $256.7 million during the three fiscal years of 2020, 2019, and 2018 due to the $1.47 billion goodwill impairment in the first quarter of 2020, compared to dividends of $1.3 billion paid by the Bank during that same period. Since the Bank had a retained deficit of $2.0 billion at December 31, 2020, for the foreseeable future, any further cash dividends from the Bank to the Company will continue to require DFPI and FDIC approval.

See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Liquidity - Holding Company Liquidity” and Note 21. Dividend Availability and Regulatory Matters of the Notes to Consolidated Financial Statements contained in “Item 8. Financial Statements and Supplementary Data” for a discussion of other factors affecting the availability of dividends and limitations on the ability to declare dividends.

Capital Requirements

We are subject to the comprehensive capital framework for U.S. banking organizations known as Basel III. Basel III, 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 credit losses, in each case, subject to Basel III specific requirements.

Pursuant to Basel III, the minimum capital ratios are as follows:

•4.5% CET1 to risk‑weighted assets;

•6.0% Tier 1 capital (that is, CET1 plus Additional Tier 1 capital) to risk‑weighted assets;

•8.0% Total capital (that is, Tier 1 capital plus Tier 2 capital) to risk‑weighted assets; and

•4% Tier 1 capital to average consolidated assets as reported on regulatory financial statements (known as the “leverage ratio”).

22

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.

Basel III provides a standardized approach for risk weightings that, depending on the nature of the assets, generally range from 0% for U.S. government and agency securities, to 1,250% for certain trading securitization exposures, resulting in higher risk weights for a variety of asset classes than previous regulations.

The Company has outstanding subordinated debentures issued to trusts, which, in turn, issued trust preferred securities. The carrying amount of subordinated debentures totaled $465.8 million at December 31, 2020. Under Basel III, none of the Company’s trust preferred securities were included in Tier 1 capital, however $451.8 million of such trust preferred securities were included in Tier 2 capital at December 31, 2020. We believe that, as of December 31, 2020, 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, 2020 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.

23

Deposit Insurance

The Bank is a state‑chartered, “non‑member” bank regulated by the DFPI 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 ratio of 1.35%. For the year ended December 31, 2020, we incurred $17.7 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 FDIC reviews, as part of its regular examination process, the Bank’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. The proposed 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. As of this filing, the agencies have not finalized these proposed regulations.

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.

24

Consumer Regulation

We are subject to a number of federal and state consumer protection laws that extensively govern our relationship with our customers. These laws include the Equal Credit Opportunity Act, the Fair Credit Reporting Act, the Truth in Lending Act, the Truth in Savings Act, the Electronic Fund Transfer Act, the Expedited Funds Availability Act, the Home Mortgage Disclosure Act, the Fair Housing Act, the Real Estate Settlement Procedures Act, the Fair Debt Collection Practices Act, the Service Members Civil Relief Act and these laws’ respective state-law counterparts, as well as state usury laws and laws regarding unfair and deceptive acts and practices. Violations of applicable consumer protection laws can result in significant potential liability from litigation brought by customers, including actual damages, restitution and attorneys’ fees. Federal bank regulators, state attorneys general and state and local consumer protection agencies may also seek to enforce consumer protection requirements and obtain these and other remedies, including regulatory sanctions, customer rescission rights, action by the state and local attorneys general in each jurisdiction in which we operate, and civil money penalties. Failure to comply with consumer protection regulations may also result in our failure to obtain any required bank regulatory approval for merger or acquisition transactions we may wish to pursue or our prohibition from engaging in such transactions even if approval is not required.

The CFPB has broad rulemaking, supervisory, and enforcement powers under various federal consumer financial protection laws. The CFPB is also authorized to engage in consumer financial education, track consumer complaints, request data, and promote the availability of financial services to underserved consumers and communities. The Bank is subject to direct oversight and examination by the CFPB. The CFPB has broad supervisory, examination, and enforcement authority over various consumer financial products and services, including the ability to require reimbursements and other payments to customers for alleged legal violations and to impose significant penalties, as well as injunctive relief that prohibits lenders from engaging in allegedly unlawful practices. The CFPB also has the authority to obtain cease and desist orders providing for affirmative relief or monetary penalties. State regulation of financial products and potential enforcement actions could also adversely affect our business, financial condition, or results of operations.

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.

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, and in December 2019, the FDIC and the Office of the Comptroller of the Currency proposed for public comment rules to modernize the agencies' regulations under the CRA. In September 2020, the FRB released for public comment its proposed rules to modernize CRA regulations. 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.

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.

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.

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 took 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

PWAM 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 PWAM 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 COVID-19 pandemic has heightened, and in some cases manifested, certain of the risks we normally face in operating our business. 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.

General Economic and Market Conditions Risk

The COVID-19 pandemic and resulting substantial disruption to global and domestic economies has adversely impacted, and is expected to continue to adversely impact our business operations, asset valuations, and financial results, and the ultimate impact on our business and financial results is uncertain.

The COVID-19 pandemic has created global and domestic economic and financial disruptions that have adversely affected, and are expected to continue to adversely affect, our business operations, asset valuations and financial results. The pandemic has negatively impacted the global and domestic economies, disrupted supply chains, lowered some equity market valuations, created significant volatility and disruption in financial markets, and increased unemployment levels at an unprecedented pace. Certain industries have been particularly hard hit, including the travel and hospitality industry, the restaurant industry and the retail industry. In addition, the pandemic has resulted in temporary closures of many businesses, the practice of social distancing, and stay-at-home requirements in many states and communities. Should economic impacts of COVID-19 persist or further deteriorate, this macroeconomic environment could have a continued adverse impact on our business, financial condition and results of operations.

The pandemic has influenced and could further influence the recognition of the provision for credit losses in our loan portfolios and has increased and could further increase our allowance for credit losses, depending on the duration of the pandemic, the ongoing impact of government stimulus and the ongoing impact on the overall economy. The provision for credit losses reflects estimates of future credit losses, however the actual credit losses that our loan portfolio may experience remains uncertain since the economic cycle is not complete, particularly as businesses remain closed and as more customers may draw on their lines of credit or seek additional loans to help finance their businesses.

Similarly, because of changing economic and market conditions affecting issuers, the securities we hold may lose value. The volatility in the equity markets has impacted our asset valuations, as evidenced by our goodwill impairment charge in the first quarter of 2020, and asset valuations of goodwill or other assets could be further impacted depending on future developments caused by COVID-19.

As an essential service, our business operations have continued during the pandemic, however they may be disrupted if significant portions of our workforce are unable to work effectively, including because of illness, quarantines, government actions, or other restrictions in connection with the pandemic. To protect the health and safety of our employees and communities most of our employees continue to work remotely, however, we have temporarily closed certain offices or have limited the capacity of employees allowed in the office. Our branch locations have adapted to the pandemic through various actions depending on the circumstances such as closing lobbies if a drive thru is available, temporarily closing if located within close proximity to another branch or at certain times reducing hours of operation. We may also experience operational difficulties, including increased cybersecurity risk, due to the remote working environments of our employees. We may also experience additional operational risk due to difficulties experienced by our third-party service providers.

28

Because there have been no comparable recent global pandemics that resulted in a similar global impact, the full extent to which the COVID-19 pandemic will impact our business operations, asset valuations and financial results will depend on future developments which remain uncertain and cannot be predicted. These include the scope and duration of the pandemic, including new strains of the virus, the efficacy and distribution of, and participation in, vaccination programs, the continued effectiveness of our business continuity plan, the direct and indirect impact of the pandemic on our employees, customers and third-party service providers, as well as other market participants, and the effectiveness of actions taken by governmental authorities and other third parties in response to the pandemic. If the pandemic continues to spread, morph or otherwise results in a continuation or worsening of the current economic and commercial environments, our business, financial condition, results of operations, cash flows, and ability to pay dividends, as well as our regulatory capital and liquidity ratios could be materially adversely affected.

COVID-19 negatively affected the U.S. and global economies and has more adversely affected certain borrowers’ abilities to repay all amounts that are contractually owed to us.

The adverse economic conditions stemming from the global COVID-19 pandemic has adversely affected the credit status of some of our borrowers. We have been monitoring certain loan portfolio segments that have been more obviously and immediately impacted. At December 31, 2020, these included hotel real estate mortgage loans, hotel construction real estate loans, and hotel and motel SBA program real estate loans that totaled $1.2 billion; retail real estate mortgage loans, retail construction real estate loans, and retail SBA program real estate loans that totaled $597.9 million; commercial aircraft loans, leases, and operating leases with passenger airlines that totaled $171.5 million; and restaurant real estate mortgage loans, restaurant SBA program real estate loans, and various restaurant commercial and industrial loans that totaled $151.0 million.

We responded by constructively working with affected borrowers, allowing for the deferral of loan payments and the extension of maturity dates, and amending our agreements with them in other ways when appropriate and warranted. Even with our actions to assist our borrowers coping with the pandemic, we may not recover all amounts contractually owed to us as noted under “Credit Risk” below.

Our business is adversely affected by unfavorable economic, market, and political conditions.

The capital and credit markets have experienced unprecedented levels of volatility and disruption over the last year. In some cases, the markets have produced downward pressure on stock prices and credit availability for certain issuers without regard to those issuers’ underlying financial strength. As a consequence of the current recession in the United States and the COVID-19 pandemic, business activity across a wide range of industries faces serious difficulties due to the lack of consumer spending and business investment. Unemployment has receded from the sharp increases in the second quarter of 2020 but remains elevated.

In the event of a sustained 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. Sources of global economic and market instability include, but are not limited to, the impact of Brexit and potential economic slowdown in Europe or the United States (but we would not expect a direct impact as we do not operate in the United Kingdom), the impact of trade negotiations, economic challenges in China, including global economic ramifications of Chinese economic difficulties, and the effects of the pandemic or other health crises. 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. Political and electoral changes, developments, conflicts and conditions (such as changes proposed by the new Presidential administration) have in the past introduced, and may in the future introduce, additional uncertainty also affect our operating results.

29

An economic recession or a downturn in various markets could have one or more of the following adverse effects on our business:

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

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

•a decrease in the value of collateral securing our loans and leases;

•an increase in the level of nonperforming and classified loans and leases:

•an increase in provisions for credit losses and loan and lease charge-offs;

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

•a decrease in the Company's stock price;

•a decrease in our ability to access the capital markets; or

•an increase in our operating expenses associated with attending to the effects of certain circumstances listed above.

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. Many borrowers have been negatively impacted by the COVID-19 pandemic and related economic consequences, and may continue to be similarly or more severely affected 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.

30

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.

Effective January 1, 2020, we adopted the Financial Accounting Standards Board (“FASB”) Accounting Standards Update 2016-13, “Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments,” commonly referred to as the “Current Expected Credit Losses” standard, or “CECL.” CECL changed the allowance for credit losses methodology from an incurred loss concept to an expected loss concept, which is more dependent on future economic forecasts, assumptions, and models than the previous accounting standards and could result in increases and add volatility to our allowance for credit losses and future provisions for loan losses. These forecasts, assumptions, and models are inherently uncertain and are based upon management’s reasonable judgment in light of information currently available. 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 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. We also cannot be certain that actual results will be consistent with forecasts and assumptions used in our CECL modeling. Any of these occurrences could materially and adversely affect our financial condition and results of operations. For more information, see Note 1(a). Nature of Operations and Summary of Significant Accounting Policies - Accounting Standards Adopted in 2020 of the Notes to Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data."

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 59% of our total loans and leases at December 31, 2020. Of total loans and leases, 36% are secured by real estate collateral located in California, 27% are secured by multi-family properties, and 6% 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, 2020, there were eight individual real estate construction and land commitments greater than or equal to $100 million with the largest commitment being $135 million. At December 31, 2020, these eight individual commitments totaled $954 million and had an aggregate outstanding balance of $526 million. The projects financed by these commitments are six multi-family projects, one mixed use property, and a hotel. For these eight commitments, the average commitment to budgeted project cost ratio was 51.7%.

At December 31, 2020, we had nine individual loan commitments greater than or equal to $150 million that ranged in size from $150 million to $400 million and totaled $1.9 billion and had an aggregate outstanding balance of $760 million. Six of these commitments totaling $1.4 billion were equity fund loans, two of these commitments totaling $350 million were lender finance loans, and one of these commitments totaling $150 million was a commercial real estate loan.

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.

31

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.

Part of our strategy is focused on providing banking products and credit to entrepreneurial and venture-backed businesses, including 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 deposit balances, 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, general economic conditions, and federal economic monetary and fiscal policies, and in particular, the Federal Reserve Board. After steadily increasing the target federal funds rate in 2018 and 2017, the Federal Reserve Board in 2019 decreased the target federal funds rate by 75 basis points, and in response to the COVID-19 pandemic in March 2020, an additional 150 basis point decrease to a range of 0.00% to 0.25% as of March 31, 2020 where it has remained. The Federal Reserve Board could make additional changes during 2021 subject to economic conditions. A prolonged low interest rate environment could negatively impact our net interest margin as assets reprice that are not subject to interest rate floors.

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 margin, asset quality, loan origination volume, average loan portfolio balance, liquidity, and overall profitability.

32

We may be adversely impacted by the transition from LIBOR as a reference rate.

In 2017, the Financial Conduct Authority announced that after 2021 it will no longer compel banks to submit the rates required to calculate the London Interbank Offered Rate (“LIBOR”). In November 2020, the administrator of LIBOR announced it will consult on its intention to extend the retirement date of certain offered rates whereby the publication of the one week and two month LIBOR offered rates will cease after December 31, 2021; but, the publication of the remaining LIBOR offered rates will continue until June 30, 2023. Given consumer protection, litigation, and reputation risks, the bank regulatory agencies have indicated that entering into new contracts that use LIBOR as a reference rate after December 31, 2021 would create safety and soundness risks and that they will examine bank practices accordingly. Therefore, the agencies encouraged banks to cease entering into new contracts that use LIBOR as a reference rate as soon as practicable and in any event by December 31, 2021.

There is uncertainty as to what rate or rates may become accepted alternatives to LIBOR, or what the effect of any such changes in views or alternatives may be on the markets for LIBOR-indexed financial instruments. In response, the Alternative Reference Rates Committee (“ARRC”) was convened in the U.S. to explore alternative reference rates and supporting processes. The ARRC identified a potential successor rate to LIBOR in the Secured Overnight Financing Rate (“SOFR”) and crafted the Paced Transition Plan to facilitate the transition. However, there are conceptual and technical differences between LIBOR and SOFR that remain unresolved at this time.

We have a significant number of loans, some securities and borrowings, such as our TruPS, and one deposit product with attributes that are either directly or indirectly dependent on LIBOR. We have not yet determined the optimal reference rate(s) that we will ultimately use for our financial instruments going forward; however, it appears likely that it will be SOFR. We have organized a multidisciplinary project team to identify operational and contractual best practices, assess our risks, identify the detailed list of all financial instruments impacted, manage the transition, facilitate communication with our customers and counterparties, and monitor the impacts. We have drafted and begun including fallback language in our loan agreements beginning in August of 2019.

The transition from LIBOR could create considerable costs and additional risk. The uncertainty as to the nature and effect of the discontinuance of LIBOR may adversely affect the value of, the return on or the expenses associated with our financial assets and liabilities that are based on or are linked to LIBOR, may require extensive changes to the contracts that govern these LIBOR-based products as well as our systems and processes, and could impact our pricing and interest rate risk models, our loan product structures, our funding costs, our valuation tools and result in increased compliance and operational costs. In addition, the market transition away from LIBOR to an alternative reference rate could prompt inquiries or other actions from regulators in respect of our preparation and readiness for the replacement of LIBOR with an alternative reference rate, and result in disputes, litigation or other actions with counterparties regarding the interpretation and enforceability of certain fallback language in LIBOR-based financial instruments. Furthermore, failure to adequately manage this transition process with our customers could adversely impact our reputation.

Although we are currently unable to assess the ultimate impact of the transition from LIBOR, the failure to adequately manage the transition could have a material adverse effect on our business, financial condition and results of operations.

The value of our securities in our investment portfolio may decline in the future.

The fair market value of our investment securities may be adversely affected by general economic and market conditions, including changes in interest rates, 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, all of which are classified as available-for-sale, on a quarterly basis to measure currently expected credit losses. The process for determining currently expected credit losses 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 credit losses in future periods, which could have a material adverse effect on our business, financial condition, or results of operations.

33

Capital and Liquidity Risk

Capital and Liquidity Risk Is the Risk of Loss Resulting from Insufficient Capital Levels or Inadequate Liquid Assets That Could Impair Our Ability to Operate Free of Regulatory Enforcement Actions and to Meet Our Contractual and Contingent Financial Obligations, On- or Off-Balance Sheet, as They Become Due.

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.

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 and borrowings from the FRBSF and FHLB. 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.

34

Regulatory, Compliance and Legal Risk

Regulatory, Compliance and Legal Risk Is the Risk of Loss Related to Violations of Laws, Rules, or Regulations, or from Non-Conformance with Prescribed Practices, Internal Policies and Procedures, Contractual Obligations and Other Legal and Ethical Standards.

Our participation in the SBA PPP loan program exposes us to risks related to noncompliance with the PPP, as well as litigation risk related to our administration of the PPP loan program, which could have a material adverse impact on our business, financial condition, and results of operations.

The Company is a participating lender in the PPP, a loan program administered through the SBA, that was created to help eligible businesses, organizations and self-employed persons fund their operational costs during the COVID-19 pandemic. Under this program, the SBA guarantees 100% of the amounts loaned under the PPP.

The PPP opened on April 3, 2020; however, because of the short window between the passing of the CARES Act and the opening of the PPP, there was some ambiguity in the laws, rules and guidance regarding the operation of the PPP. Subsequent rounds of legislation and associated agency guidance have not provided necessary clarity and have created potential additional inconsistencies and ambiguities. Accordingly, the Company is exposed to risks relating to noncompliance with the PPP.

Additionally, since the launch of the PPP, several larger banks have been subject to litigation regarding the process and procedures that such banks used in processing applications for the PPP, as well as litigation regarding the alleged nonpayment of fees that may be due to certain agents who facilitated PPP loan applications. The Company may be exposed to the risk of litigation, from both customers and non-customers that approached the Bank regarding PPP loans, regarding its process and procedures used in processing applications for the PPP. If any such litigation is filed against the Company and is not resolved in a manner favorable to the Company, it may result in significant financial liability or adversely affect the Company’s reputation. Regardless of outcome, litigation can be costly and distracting. Any financial liability, litigation costs or reputational damage caused by PPP-related litigation could have a material adverse impact on our business, financial condition and results of operations.

PPP loans are fixed, low interest rate loans that are guaranteed by the SBA and subject to numerous other regulatory requirements, and a borrower may apply to have all or a portion of the loan forgiven. If PPP borrowers fail to qualify for loan forgiveness, we face a heightened risk of holding these loans at unfavorable interest rates for an extended period of time. While the PPP loans are guaranteed by the SBA, various regulatory requirements will apply to our ability to seek recourse under the guarantees, and related procedures are currently subject to uncertainty.

In addition, the Company may be exposed to credit risk on PPP loans if a determination is made by the SBA that there is a deficiency in the manner in which the loan was originated, funded, or serviced, such as an issue with the eligibility of borrower to receive a PPP loan, which may or may not be related to the ambiguity in the laws, rules and guidance regarding the operations of the PPP. If a deficiency is identified, the SBA may deny its liability under the guaranty, reduce the amount of the guaranty, or, if it has already paid under the guaranty, seek recovery of any loss related to the deficiency from the Company.

35

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, DFPI 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, the establishment of new branch offices by the Bank, maintenance of adequate capital and liquidity, restrictions on dividends, and stock repurchases. 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 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 frequently 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. There can be no assurance that laws, rules, and regulations, including any future government stabilization program, will not be proposed or adopted in the future, which could (i) subject us to additional restrictions, (ii) make compliance much more difficult or expensive, (iii) restrict our ability to originate, broker, or sell loans or accept certain deposits, (iv) further limit or restrict the amount of commissions, interest, or other charges earned on loans originated or sold, or (v) otherwise materially and adversely affect our business or prospects for business. While new legislation in 2018 scaled back portions of the Dodd-Frank Act, the new administration in the United States may adopt, enhance or modify bank regulation, and any such new, enhanced or modified regulations could adversely affect our financial condition or results of operations.

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 internal capital stress test 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 taxes due. These examinations may relate to income, franchise, gross receipts, payroll, property, sales and use, or other tax returns. 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.

36

We are subject to claims and litigation which could adversely affect our cash flows, financial condition, and results of operations, or cause us significant reputational harm.

We and certain of our directors, officers, and subsidiaries may be involved, from time to time, in reviews, investigations, litigation, and other proceedings pertaining to our business activities. If claims or legal actions, whether founded or unfounded, are not resolved in a favorable manner to us, they may result in significant financial liability. Although we establish accruals for legal matters when and as required by 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.

Regulations relating to privacy, information security, and data protection could increase our costs, affect or limit how we collect and use personal information, and adversely affect our business opportunities.

We are subject to various privacy, information security and data protection laws, such as the Gramm-Leach-Bliley Act, which among other things requires privacy disclosures, and maintenance of a robust security program that are increasingly subject to change which could have a significant impact on our current and planned privacy, data protection and information security-related practices, our collection, use, sharing, retention and safeguarding of consumer or employee information, and some of our current or planned business activities. We are also subject to the recently enacted California Consumer Privacy Act of 2018 (“CCPA”), which came into effect on January 1, 2020, and provides a new private right of action for data breaches and requires companies that process information on California residents to make new disclosures to consumers about their data collection, use and sharing practices and allow consumers to opt out of certain data sharing with third parties. Our regulators also hold us responsible for privacy and data protection obligations performed by our third party service providers while providing services to us.

New or changes to existing laws increase our costs of compliance and business operations and could reduce income from certain business initiatives, including increased privacy-related enforcement activity, higher compliance and technology costs and could restrict our ability to provide certain products and services. Our failure to comply with privacy, data protection and information security laws could result in potentially significant regulatory or governmental investigations or actions, litigation, fines, sanctions and damage to our reputation, which could have a material adverse effect on our business, financial condition or results of operations.

Risk of the Competitive Environment in which We Operate

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. Losses of or changes in our current executive officers or other key personnel, or the inability to recruit and retain qualified personnel in the future could materially and adversely affect our financial condition and results of operations.

37

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.

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. Many of our competitors, however, have substantially greater resources to invest in technological improvements or are technology focused start-ups with internally developed cloud-native systems that offer improved user interfaces and experiences. 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.

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.

38

Risks Related to Risk Management

Risks Related to Risk Management Is the Risk of Loss Resulting from Unknown Risks and Our Inability to Timely and Adequately Identify, Monitor and Manage Key Risks That May Affect Our Business.

Our acquisitions may subject us to unknown risks.

As an active acquirer having successfully completed 30 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 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.

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.

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.

39

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. Similar to other companies, risks and exposures related to cybersecurity attacks have increased as a result of the COVID-19 pandemic, the related increased reliance on remote working and increase in digital operations in efforts to comply with state and local mandates. Such risks and exposures are expected to remain high for the foreseeable future due to the rapidly evolving nature and sophistication of these threats and the expanding use of technology, 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.

Severe weather, natural disasters, acts of war or terrorism, new public health issues, or other adverse external events could harm the Company's business.

Severe weather, natural disasters, acts of war or terrorism, new public health issues, 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. Moreover, a new public health issue, such as a major epidemic or another pandemic, could adversely affect economic conditions. Severe weather, natural disasters, acts of war or terrorism, public health issues, or other adverse external events could each 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

Risk from Accounting and Other Estimates Is the Risk That the Estimates and Assumptions That We Use in Preparing Our Consolidated Financial Statements and In Models We Utilize to Make Business Decisions May Be Subject to Adjustment for Reasons Within or Beyond Our Control, Which Could Result in Unexpected Losses and Adverse Effects on Our Financial Condition.

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, particularly in light of the adoption of the new CECL standard on January 1, 2020; the carrying value of goodwill or other 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. Models are often based on historical experience to predict future outcomes, as a result new experiences or events which are not part of historical experience can significantly increase model imprecision and impact model reliability. Model inputs can also include information provided by third parties, such as economic forecasts or macroeconomic variables (unemployment, Real GDP etc.) upon which we rely. 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. Our reliance on models continues to increase as rules, guidance and expectations change. The most recent example of this is the additional models used in the determination of our allowance for credit losses under CECL, which we adopted on January 1, 2020.

Risks Related to Investments in Our Securities

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 DFPI 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 DFPI 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. The Bank had a net loss of $256.7 million during the three fiscal years of 2020, 2019, and 2018 due to the $1.47 billion goodwill impairment in the first quarter of 2020, compared to dividends of $1.3 billion paid by the Bank during that same period. During 2020, PacWest received $258.0 million in dividends from the Bank. Since the Bank had an accumulated deficit of $2.0 billion at December 31, 2020, for the foreseeable future, any cash dividends from the Bank to the holding company will continue to require DFPI 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 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 during any period in which our quarterly and/or cumulative twelve-month net earnings are insufficient to fund the dividend amount, among other requirements. The Company reported a net loss of $1.2 billion in 2020 due primarily to the $1.47 billion goodwill impairment recorded in the first quarter of 2020. 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.

ITEM 7. 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 70 full-service branches located in California, one branch located in Durham, North Carolina, one branch located in Denver, Colorado, and numerous loan production offices across the country. The Bank provides community banking products including lending and comprehensive deposit and treasury management services to small and medium-sized businesses conducted primarily through our California-based branch offices and Denver, Colorado branch office. The Bank offers national lending products including asset-based, equipment, and real estate loans and treasury management services to established middle-market businesses on a national basis. The Bank also offers venture banking products including a comprehensive suite of financial services focused on entrepreneurial and venture-backed 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 Pacific Western Asset Management Inc., a wholly-owned subsidiary of the Bank and an SEC-registered investment adviser.

At December 31, 2020, the Company had total assets of $29.5 billion, including $19.1 billion of total loans and leases, net of deferred fees, and $5.2 billion of securities available-for-sale, compared to $26.8 billion of total assets, including $18.8 billion of total loans and leases, net of deferred fees, and $3.8 billion of securities available-for-sale at December 31, 2019. The $2.7 billion increase in total assets since year-end was due primarily to a $2.5 billion increase in interest-earning deposits in financial institutions and a $1.4 billion increase in securities available-for-sale, offset partially by a $1.47 billion write-down of goodwill.

At December 31, 2020, the Company had total liabilities of $25.9 billion, including total deposits of $24.9 billion and borrowings of $5.0 million, compared to $21.8 billion of total liabilities, including $19.2 billion of total deposits and $1.8 billion of borrowings at December 31, 2019. The $4.1 billion increase in total liabilities since year-end was due mainly to increases of $6.1 billion in core deposits and $653.1 million in non-core non-maturity deposits, offset partially by decreases of $1.8 billion in borrowings, primarily FHLB advances, and $1.0 billion in time deposits. The increase in core deposits was due primarily to capital market activities by our venture banking clients, which saw deposits increase by $3.9 billion to $11.0 billion at December 31, 2020, and to PPP loan proceeds being deposited into customers' accounts. At December 31, 2020, core deposits totaled $22.3 billion, or 89% of total deposits, including $9.2 billion of noninterest-bearing demand deposits, or 37% of total deposits.

At December 31, 2020, the Company had total stockholders' equity of $3.6 billion compared to $5.0 billion at December 31, 2019. The $1.36 billion decrease in stockholders' equity since year-end was due mainly to a $1.24 billion net loss, attributable primarily to a $1.47 billion goodwill impairment charge, $159.7 million of cash dividends paid, and $70.0 million of common stock repurchased under the Stock Repurchase Program, offset partially by a $93.9 million increase in accumulated other comprehensive income. Consolidated capital ratios remained strong and continued to increase with Tier 1 capital and total capital ratios of 10.53% and 13.76% at December 31, 2020, up 75 basis points and 135 basis points compared to December 31, 2019.

Recent Events

Acquisition of Civic Ventures, LLC

On February 1, 2021, the Bank acquired Civic Ventures, LLC and subsidiaries (“Civic”) in an all-cash transaction. The acquisition is not considered significant under SEC regulations. Civic Financial Services is the primary operating entity of Civic. Civic is one of the leading institutional private lenders in the United States specializing in residential non-owner-occupied investment properties. Civic will operate as a wholly-owned subsidiary of the Bank. The acquisition of Civic advances the Bank’s strategy to expand its lending portfolio and diversify its revenue streams.

COVID-19 Pandemic

The outbreak of the Coronavirus Disease ("COVID-19") pandemic has impacted our business and operations in several ways as outlined below. Our first and continuing priority remains the safety and health of our employees and customers as we navigate our way through the pandemic. In the first quarter of 2020, we activated our Business Continuity Team and Pandemic Plan under the direction of a special task force comprised of executive level management from various departments to work closely with the Business Continuity Team to help lead our people and our business through this period of uncertainty. The special task force has continued to meet at least weekly since the onset of the pandemic.

Our Employees

We took several actions in March 2020 to move everyone possible to a remote working environment, which has continued to this day; however, as an essential business service, some of our employees are required to work at one of our critical offices or at one of our branch locations where we are practicing social distancing and other safety measures. We have applied social distancing, wearing of face masks, remote working, additional cleaning, reminders of frequent handwashing, installation of plexiglass barriers among other steps to ensure the health and safety of employees and customers. We suspended all employee business travel and canceled all hosted client events. We require anyone who has traveled personally to a foreign country or on a cruise, to self-quarantine for 14 days. Despite these restrictions, we have remained fully operational and able to meet the needs of our clients and the communities we serve. To recognize our employees who must work in our branches or critical locations, we paid a special bonus of up to $1,000 in the second quarter of 2020. We have begun to re-open some office locations if permitted under local government guidance, but any such re-openings generally remain limited to no more than a 50% capacity. Despite some re-openings, the vast majority of our non-branch employees continue to work remotely.

Our Clients and Branch Operations

Our primary branch operations are within California, which continues to work its way through the State's Resilience Roadmap from the initial "Stay-at-home" order issued on March 13, 2020 to the subsequent executive orders and phased-in guidance issued for re-openings. As a large state, the stages of re-opening vary by county and thus the impact to our operations varies by county. At the outset of the COVID-19 pandemic, we closed 19 branches along with the lobbies of 27 additional branches where drive-up tellers are available. In June 2020, we re-opened 17 of the 19 branches and decided to permanently close two branches in the third quarter and two more branches in the fourth quarter. In February 2021, we re-opened the 27 lobbies and are now operating all branches normally. We continue to monitor the pandemic's impact on our branch operations and have alternative plans in place in the event we need to reduce branch hours, temporarily close branches in close proximity to each other, or stagger the hours of our employees, all in an effort to keep our employees and customers safe while meeting the needs of our customers.

Impact to Our Business

From a business perspective, the impacts in 2020 from the COVID-19 pandemic have been primarily related to our loan portfolio. In the early stages of the COVID-19 pandemic, we experienced an increase in customers seeking loan modifications through payment deferrals and extension of terms. As of December 31, 2020, active loan payment deferral modifications represented approximately 0.8% of the loan portfolio, down from approximately 6.6% of the loan portfolio at June 30, 2020. Most of the modifications were for payment deferrals for three months, while some deferrals were up to six months. The remaining $155 million of loans on deferral as of December 31, 2020 expire by June 30, 2021.We also granted maturity extensions totaling approximately $376 million primarily for three months, while some extensions were for one year. The Company did not apply a TDR classification to COVID-19 related loan modifications that met all of the requisite criteria as stipulated in the CARES Act.

We actively participated in the Paycheck Protection Program ("PPP"), under the provisions of the Coronavirus Aid, Relief, and Economic Security ("CARES") Act by funding approximately 4,100 loans, most with two year terms, for $1.2 billion. As of December 31, 2020, PPP loans had an outstanding balance of approximately $1.1 billion. The loans have two or three year terms with a 1% loan coupon rate and origination fees that varied from 1% to 5% depending on the size of the loan. These fees, which originally totaled approximately $36.4 million, are recognized over the life of the loan with the fee recognition accelerated upon forgiveness or repayment of the loan. As of December 31, 2020, the remaining unamortized fees, net of deferred costs, totaled $19.4 million. The PPP loans are fully guaranteed by the SBA and do not carry an allowance. Our participation in the PPP resulted in a corresponding increase in core deposits in the second quarter of 2020 due to PPP loan proceeds being deposited into customers' accounts. We intend to participate in the second round of the PPP program in 2021, but expect the dollar amount of loans funded to be less than the original program.

As the COVID-19 pandemic unfolded in March 2020, we immediately enhanced the monitoring of our loan and lease portfolio with particular emphasis on certain loan and lease portfolios that we expected to be most impacted by the COVID-19 pandemic, such as the hotel, retail, commercial aviation, restaurant, and oil services loan and lease portfolios. The hotel portfolio as of December 31, 2020 is comprised of hotel CRE loans of $571.9 million, hotel construction loans of $549.0 million, and hotel SBA loans of $29.6 million. The economic impacts caused by the COVID-19 pandemic precipitated loan and lease risk rating downgrades across these loan and lease portfolios, resulting in increases of $398.3 million in special mention loans and $89.4 million in classified loans during the year ended December 31, 2020, most of which occurred in the first quarter.

The table below shows our exposure to these loan and lease portfolios, which includes equipment leased to others under operating leases, as of the date indicated:

The deterioration in economic conditions caused by the COVID-19 pandemic has significantly impacted the economic forecasts and assumptions used in our estimation process for the allowance for credit losses under CECL. Although our provision for credit losses for the fourth quarter of 2020 decreased by $87.0 million from the third quarter of 2020 to $10.0 million, the provision for credit losses increased by $317.0 million to $339.0 million during the year ended December 31, 2020 when compared to the same period in 2019. Deterioration in the macro-economic variables used in economic forecasts we utilize in our allowance for credit losses estimation has contributed to a higher provision for credit losses for the year. For further details on CECL and the impacts to our process in the year, see “- Balance Sheet Analysis - Allowance for Credit Losses on Loans and Leases Held for Investment” contained herein. .

During the first quarter of 2020, the economic impact of the COVID-19 pandemic also resulted in market volatility and a significant decline in stock market valuations, including our stock price. As a result, we performed a goodwill impairment assessment and recorded goodwill impairment of $1.47 billion in the first quarter, as the estimated fair value of equity was less than book value as of March 31, 2020. This is a non-cash charge and had no impact on our regulatory capital ratios, cash flows, or liquidity position. The goodwill impairment charge resulted in a net loss of $1.43 billion in the first quarter and although our net earnings excluding the goodwill impairment charge were $36.9 million, or $0.31 per diluted share, the results contributed to our decision to reduce our quarterly dividend from $0.60 per share to $0.25 per share beginning in the second quarter.

On March 23, 2020, we announced the temporary suspension of share repurchases under our stock repurchase program until June 30, 2020 and, subsequently announced on April 21, 2020, the indefinite suspension of any repurchases in light of the COVID-19 pandemic. We have not repurchased any shares since February 28, 2020.

Looking ahead, we expect the operating environment to remain challenging as the duration of the pandemic remains uncertain. The timing and extent of vaccination programs will play an integral role in easing or lifting various restrictions thereby influencing the economic recovery. The economic forecasts will continue to impact our calculations for determining the allowance for credit losses and related provision for credit losses.

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 investment securities based on a 21% federal statutory tax rate. 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 and borrowings. 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 and leases portfolio is diverse and generally includes various asset-secured loans, equipment-secured loans and leases, venture capital loans to support venture capital firms’ operations and the operations of entrepreneurial and venture-backed companies during the various phases of their early life cycles, and secured business loans.

52

Our loan origination process emphasizes credit quality. To augment our internal loan production, we have historically purchased multi-family loans from other banks, private student loans from third-party lenders, and single-family renovation construction loans from Civic. 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. 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.

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 the allowance for loan and lease losses and the 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 exposures. Loans and leases that 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 the impact of assumptions and is reflective of historical experience, economic forecasts viewed to be reasonable and supportable by management, the current loan and lease composition, and relative credit risks known as of the balance sheet date. For originated and acquired credit-deteriorated 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 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, which is calculated by dividing noninterest expense (less intangible asset amortization, net foreclosed assets expense (income), goodwill impairment, and acquisition, integration and reorganization costs) by net revenues (the sum of tax equivalent net interest income plus noninterest income, less gain (loss) on sale of securities and gain (loss) on sales of assets other than loans and leases).

Critical Accounting Policies and Estimates

The following discussion and analysis of financial condition and results of operations are based upon our consolidated financial statements and the notes thereto, which have been prepared in accordance with U.S. GAAP. The preparation of the consolidated financial statements requires us to make a number of estimates and assumptions that affect the reported amounts and disclosures in the consolidated financial statements. On an ongoing basis, we evaluate our estimates and assumptions based upon historical experience and various other factors and circumstances. We believe that our estimates and assumptions are reasonable; however, actual results may 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 three 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, the carrying value of goodwill and other intangible assets, and the realization of deferred income tax assets and liabilities.

Allowance for Credit Losses on Loans and Leases Held for Investment

For information regarding the calculation and policies of the allowance for credit losses on loans and leases held for investment using the CECL methodology effective January 1, 2020, see " - Balance Sheet Analysis - Allowance for Credit Losses on Loans and Leases Held for Investment" and "Note 1. Nature of Operations and Summary of Significant Accounting Policies - (a) Accounting Standards Adopted in 2020" and "(i) Allowance for Credit Losses on Loans and Leases Held for Investment" of the Notes to Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data."

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 annually unless a triggering event occurs thereby requiring an updated assessment. Our regular annual impairment assessment occurs in the fourth quarter. Goodwill represents the excess of the purchase price over the fair value of the net assets and other identifiable intangible assets acquired. Impairment exists when the carrying value of the goodwill exceeds its 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 (loss).

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 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.

55

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:

•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. In 2020, we changed the calculation of return on average tangible equity to add back intangible asset amortization to net earnings to arrive at adjusted net earnings. Prior periods have been conformed to the current period presentation. The reconciliations of these non-GAAP measurements to the GAAP measurements are presented in the following tables for and as of the periods presented.

Results of Operations

Earnings Performance

2020 Compared to 2019

Net loss for the year ended December 31, 2020 was $1.24 billion, or $10.61 per diluted share, compared to net earnings for the year ended December 31, 2019 of $468.6 million, or $3.90 per diluted share. The $1.71 billion decrease in net earnings was due primarily to a $1.47 billion goodwill impairment charge in the first quarter of 2020, a higher provision for credit losses of $317.0 million, and higher operating expense of $11.8 million, offset partially by higher noninterest income of $3.5 million and lower income tax expense of $89.1 million. The increase in the provision for credit losses for 2020 was the result of the impact of the current economic forecast used in our ACL estimation, which reflected a significant deterioration in key macro-economic forecast variables such as unemployment and GDP growth as a result of the COVID-19 pandemic. The increase in operating expense was due mainly to increases of $9.1 million in other expense, $6.2 million in insurance and assessments, $4.8 million in leased equipment depreciation, $3.7 million in customer related expense, and $3.5 million in foreclosed assets expense, offset partially by decreases of $14.4 million in compensation expense and $4.0 million in intangible asset amortization. The increase in noninterest income for 2020 was due primarily to a $15.6 million increase in dividends and gain on equity investments, offset partially by a $12.3 million decrease in gain on sale of securities.

2019 Compared to 2018

Net earnings for the year ended December 31, 2019 were $468.6 million, or $3.90 per diluted share, compared to net earnings for the year ended December 31, 2018 of $465.3 million, or $3.72 per diluted share. The $3.3 million increase in net earnings was due to a lower provision for credit losses of $23.0 million, lower noninterest expense of $9.0 million, and lower income tax expense of $3.7 million, offset partially by lower net interest income of $26.3 million and lower noninterest income of $6.1 million.

The provision for credit losses decreased due mainly to lower specific provisions for impaired loans during 2019 and lower provisions related to the reserve for unfunded loan commitments during 2019 due to updates on utilization factors which estimate the percentage of available credit that will be utilized by our borrowers.

Noninterest expense declined due principally to lower other expense of $8.8 million. Other expense decreased due mostly to $2.1 million of lower amortization of non-competition agreements, $2.0 million in lower franchise tax expense, a $1.7 million reversal of previously accrued merger costs, $1.3 million in lower employee related expenses, and $1.1 million in lower operating and other losses.

Net interest income decreased due to interest expense growth of $84.5 million exceeding interest income growth of $58.2 million. Interest expense increased due to the cost of deposits increasing to 0.77% in 2019 compared to 0.44% in 2018 due mainly to higher rates paid on deposits in conjunction with increased market rates. Interest income increased due primarily to a higher average balance of loans and leases, partially offset by a lower yield on loans and leases due to lower discount accretion and from de-risking initiatives which have resulted in lower yields on newly originated loans compared to the yields on loans that have matured and paid off.

Noninterest income declined due mostly to lower other income of $13.7 million, lower dividends and gains on equity investments of $4.4 million, a lower gain on sale of loans of $3.6 million, and lower other commissions and fees of $1.9 million, offset partially by a higher gain on sale of securities of $17.3 million. Other income declined due primarily to lower gains on early lease terminations, lower legal settlements with former borrowers, and lower BOLI income. Dividends and gains on equity investments declined due primarily to lower gains on the sale of equity investments and lower dividends received in 2019 as compared to 2018 as a significant portion of our equity investments were sold in the second quarter of 2018. Gain on sale of loans declined due to a net gain of $1.1 million on sales of $101.5 million of loans in 2019 compared to a net gain of $4.7 million on sales of $641.9 million of loans during 2018. Other commissions and fees decreased due primarily to lower loan prepayment penalty fees offset partially by higher foreign exchange fees, unused commitment fees and customer success fees. Gain on sale of securities increased due mainly to a net gain of $25.4 million on sales of $1.6 billion of securities in 2019 compared to a net gain of $8.2 million on sales of $563.6 million in 2018.

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 yields earned on average interest‑earning assets and rates paid on average interest‑bearing liabilities are referred to as changes in “rate.” The changes in the amounts of average interest‑earning assets and interest‑bearing liabilities are referred to as changes in “volume.” 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 attributable to volume reflects the change in volume multiplied by the prior year’s rate. The change in interest income/expense not attributable specifically to either rate or volume is allocated ratably between the two categories.

The following table presents changes in interest income (tax equivalent) and interest expense and related changes in rate and volume for the years indicated:

(1)    Tax equivalent.

2020 Compared to 2019

Net interest income held steady at $1.01 billion for both the year ended December 31, 2020 and the year ended December 31, 2019 due mainly to a lower yield on average loans and leases, offset partially by a lower cost of average interest-bearing deposits and a higher balance of average loans and leases. The tax equivalent yield on average loans and leases was 5.18% for the year ended December 31, 2020 compared to 6.00% for 2019. The decrease in the yield on average loans and leases was due mainly to lower loan coupon interest from the repricing of variable-rate loans in conjunction with decreased market rates and a lower rate on loan production from the impact of the PPP loans. Excluding the PPP loans, which have a coupon rate of 1%, the tax equivalent yield on average loans and leases was 5.27% in 2020.

60

The tax equivalent NIM for the year ended December 31, 2020 was 4.05% compared to 4.54% for the year ended December 31, 2019. The decrease in the tax equivalent NIM was due mostly to the decrease in the yield on average loans and leases as described above, offset partially by the lower cost of average interest-bearing deposits. Excluding the PPP loans, the tax equivalent NIM was 4.08% for the year ended December 31, 2020.

The cost of average total deposits decreased to 0.27% for the year ended December 31, 2020 from 0.77% for 2019 due mainly to lower rates paid on deposits resulting from decreased market rates.

2019 Compared to 2018

Net interest income decreased by $26.3 million to $1.01 billion for the year ended December 31, 2019 compared to $1.04 billion for the year ended December 31, 2018 due to interest expense growth exceeding interest income growth. Interest expense increased by $84.5 million due mainly to a higher cost and balance of average interest-bearing deposits, a lower balance of average noninterest-bearing deposits, and a higher balance and cost of average borrowings. Interest income increased by $58.2 million due primarily to a higher balance of average loans and leases, offset partially by a lower rate on average loans and leases. The tax equivalent yield on average loans and leases was 6.00% for the year ended December 31, 2019 compared to 6.22% for 2018. The decrease in the yield on average loans and leases was due in part to lower discount accretion on acquired loans (seven basis points for 2019 compared to 17 basis points for 2018). The decrease in the average loan and lease yield was also influenced by the credit de-risking initiatives taken over the last couple of years which has seen the replacement of higher yielding loans, such as cash flow, with lower yielding multi-family and equity fund loans. These factors were partially offset by upward repricing of variable-rate loans attributable to four quarter-point increases in the fed funds target rate during 2018 and in effect through the first half of 2019, only recently mitigated by three quarter-point cuts to the fed funds target rate during the second half of 2019.

The tax equivalent NIM for the year ended December 31, 2019 was 4.54% compared to 5.05% for the year ended December 31, 2018. The decrease in the tax equivalent NIM was due mostly to higher deposit and borrowing costs, as well as the decrease in the yield on average loans and leases as described above. Total discount accretion on acquired loans contributed six basis points to the NIM for year ended December 31, 2019 compared to 14 basis points for 2018.

The cost of average total deposits increased to 0.77% for the year ended December 31, 2019 from 0.44% for 2018 due mainly to higher rates paid on deposits in conjunction with increased market rates, along with a shift in our deposit mix resulting from increases in average interest-bearing deposits and a decrease in average noninterest-bearing demand deposits.

______________________

(1)    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 provision for credit losses increased by $317.0 million to $339.0 million for the year ended December 31, 2020 compared to $22.0 million for the year ended December 31, 2019 primarily as a result of the impact of the current economic forecast used in our ACL estimation, which reflected a significant deterioration in key macro-economic forecast variables such as unemployment and GDP growth as a result of the COVID-19 pandemic.

The provision for credit losses declined by $23.0 million to $22.0 million for the year ended December 31, 2019 compared to $45.0 million for the year ended December 31, 2018 due mainly to lower specific provisions for impaired loans during 2019 and lower provisions related to the reserve for unfunded loan commitments during 2019 due to updates on utilization factors which estimate the percentage of available credit that will be utilized by our borrowers.

62

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 nonperforming loans and leases, net loan and lease and unfunded commitment growth, and changes in economic conditions and forecasts. Changes in economic conditions and forecasts include the rate of economic growth, the unemployment rate, the rate of inflation, changes in the general level of interest rates, changes in real estate values, and adverse conditions in borrowers’ businesses. For information regarding the allowance for credit losses on loans and leases held for investment, see "- Critical Accounting Policies and Estimates - Allowance for Credit Losses on Loans and Leases Held for Investment," "- Balance Sheet Analysis - Allowance for Credit Losses on Loans and Leases Held for Investment," Note 1(i).

2020 Compared to 2019

Noninterest income increased by $3.5 million to $146.1 million for the year ended December 31, 2020 compared to $142.6 million for the year ended December 31, 2019 due mainly to increases of $15.6 million in dividends and gains on equity investments and $4.9 million in leased equipment income, offset partially by decreases of $12.3 million in gain on sale of securities, $4.3 million in service charges on deposit accounts, and $3.3 million in other commissions and fees. Dividends and gains on equity investments increased due primarily to increases in the fair value of equity investments still held and higher gains on sale of equity investments sold. Leased equipment income increased due to early lease terminations resulting in higher termination gains in the year ended December 31, 2020 as compared to the year ended December 31, 2019 and a higher average balance of leases in 2020 resulting in higher lease income as compared to 2019, offset partially by lower rental income attributable to two operating leases placed on nonaccrual status in 2020. The decrease in gain on sale of securities resulted from the sale of $160.3 million of securities for a gain of $13.2 million for the year ended December 31, 2020 compared to sales of $1.6 billion of securities for a gain of $25.4 million for the year ended December 31, 2019. Service charges on deposit accounts decreased due primarily to lower analysis fees and NSF fees for the year ended December 31, 2020 as compared to last year as we waived certain fees for a period of time as part of our response to the COVID-19 pandemic. Other commissions and fees decreased primarily due to lower credit card fee income and lower foreign exchange fees, offset partially by higher customer success fees.

63

2019 Compared to 2018

Noninterest income declined by $6.1 million to $142.6 million for the year ended December 31, 2019 compared to $148.6 million for the year ended December 31, 2018 due mostly to decreases of $13.7 million in other income, $4.4 million in dividends and gains on equity investments, $3.6 million in gain on sale of loans and leases, and $1.9 million in other commissions and fees, offset partially by an increase in gain on sale of securities of $17.3 million. Other income declined due primarily to lower gains on early lease terminations, lower legal settlements with former borrowers, and lower BOLI income. Dividends and gains on equity investments decreased due primarily to lower gains on the sale of equity investments and lower dividends received in 2019 as compared to 2018 as a significant portion of our equity investments were sold in the second quarter of 2018. Gain on sale of loans and leases declined due to a net gain of $1.1 million on sales of $101.5 million of loans and leases during 2019 compared to a net gain of $4.7 million on sales of $641.9 million of loans and leases during 2018. The loans and leases sold during 2018 included the sale of a large nonaccrual loan for a $2.4 million gain and the settlement of our December 31, 2017 loans held for sale of $481.1 million for a $1.3 million gain. Other commissions and fees decreased due primarily to lower loan prepayment penalty fees of $4.2 million, offset partially by higher foreign exchange fees of $0.8 million, higher unused commitment fees of $0.8 million, and higher customer success fees of $0.5 million. Gain on sale of securities increased due mainly to a net gain of $25.4 million on sales of $1.6 billion of securities during the year ended December 31, 2019 compared to a net gain of $8.2 million on sales of $563.6 million of securities during 2018. The higher gain on sale of securities in 2019 is due primarily to the repositioning of a portion of our securities portfolio in the second quarter of 2019 to shorten the duration of the portfolio, to enhance liquidity, and to take advantage of municipal security price appreciation due to market dynamics from tax law changes. The securities sold in 2018 included $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.

Noninterest expense increased by $1.48 billion to $1.98 billion for the year ended December 31, 2020 compared to $502.3 million for the year ended December 31, 2019 due mainly to a $1.47 billion goodwill impairment charge incurred in the first quarter of 2020. Excluding the goodwill impairment charge, noninterest expense increased by $11.8 million to $514.0 million in 2020. This increase was due mainly to increases of $9.1 million in other expense, $6.2 million in insurance and assessments, $4.8 million in leased equipment depreciation, $3.7 million in customer related expense, and $3.5 million in foreclosed assets expense, offset partially by decreases of $14.4 million in compensation expense and $4.0 million in intangible asset amortization. Other expense increased due mainly to $6.6 million in prepayment penalties incurred in the second quarter of 2020 from the early payoff of $750 million of FHLB term advances and higher litigation accruals, offset partially by lower business development expenses and employee related expenses as a result of COVID-19. Insurance and assessments expense increased due primarily to an increase in our FDIC assessment rate as a result of the first quarter 2020 loss from the goodwill impairment charge. Leased equipment depreciation increased due principally to a higher average balance of leased equipment. Customer related expenses increased due mostly to higher customer analysis expenses and reciprocal deposit referral fees. Foreclosed assets expense increased due principally to lower gains on the sale of foreclosed assets. Compensation expense decreased due mainly to lower bonus expense in the 2020 period compared to the prior year based on Company financial performance in 2020. Intangible asset amortization decreased due mostly to lower CDI amortization related to financial institutions acquired in 2015 and 2017.

2019 Compared to 2018

Noninterest expense decreased by $9.0 million to $502.3 million for the year ended December 31, 2019 compared to $511.2 million for the year ended December 31, 2018 due primarily to a decline in other expense of $8.8 million. Other expense decreased due mostly to $2.1 million of lower amortization of non-competition agreements, $2.0 million in lower franchise tax expense, a $1.7 million reversal of previously accrued merger costs, $1.3 million in lower employee related expenses, and $1.1 million in lower operating and other losses. There were also noteworthy year-over-year fluctuations in compensation expense, occupancy expense, other professional services expense, insurance and assessments expense, customer related expense, and foreclosed assets (income) expense, net. Compensation expense increased due primarily to higher bonus expense attributable to achievement of performance metrics in excess of targets. Occupancy expense increased due mainly to an increased number of office locations. Other professional services expense decreased mostly as a result of lower legal and consulting expense. Insurance and assessments expense decreased primarily due to the 4.5 basis point FDIC surcharge ending in the third quarter of 2018. Customer related expense increased due to an increase in the number of deposit customers on analysis and a higher utilization of analysis credits by customers to pay third-party expenses. Foreclosed assets (income) expense, net, increased mainly due to higher gains on the sale of foreclosed assets

Income Taxes

The effective tax rates were (6.5)%, 26.0% and 26.5% for the years ended December 31, 2020, 2019, and 2018. Excluding non-deductible goodwill impairment, the effective income tax rate was 24.4% for the year ended December 31, 2020. The 2020 effective tax rate of 24.4%, adjusted for non-deductible goodwill impairment, was lower than the 2019 effective tax rate of 26.0% attributable primarily to tax benefits from amended state tax returns of prior tax years due to changes in state apportionment rates. The Company's 2020 blended statutory tax rate for federal and state was 27.7%. For further information on income taxes, see Note 15. Income Taxes of the Notes to Consolidated Financial Statements contained in “Item 8. Financial Statements and Supplementary Data.”

Fourth Quarter of 2020 Compared to Third Quarter of 2020

Net earnings were $116.8 million, or $0.99 per diluted share, for the fourth quarter of 2020 compared to $45.5 million, or $0.38 per diluted share, for the third quarter of 2020. The quarter‑over‑quarter increase in net earnings of $71.3 million was due to a lower provision for credit losses of $87.0 million, higher net interest income of $7.9 million, and higher noninterest income of $1.6 million, offset partially by higher noninterest expense of $2.3 million, and higher income tax expense of $22.9 million.

The provision for credit losses declined due to improvement in certain key macro-economic forecast variables, a lower provision for unfunded loan commitments, and decreased provisions for individually evaluated loans and leases.

67

Net interest income increased by $7.9 million to $259.2 million for the fourth quarter of 2020 compared to $251.3 million for the third quarter of 2020 due mainly to higher income on investment securities, higher loan prepayment fees, higher recapture of nonaccrual interest, higher amortized loan fee income from PPP loan forgiveness, and lower interest expense, offset partially by a negative impact on net interest income due the change in earning assets mix and a lower average balance of average loans and leases. The tax equivalent yield on average loans and leases was 5.15% for the fourth quarter of 2020 compared to 5.01% for the third quarter of 2020. The increase in the tax equivalent yield on average loans and leases was due primarily to higher loan prepayment fees, higher recapture of nonaccrual interest, and higher amortized loan fee income from PPP loan forgiveness in the fourth quarter as compared to the third quarter.

The tax equivalent NIM was 3.83% for the fourth quarter of 2020 compared to 3.90% for the third quarter of 2020. The decrease in the NIM was due mostly to the change in the earning assets mix. Average loans and leases decreased by $426.5 million, while the average balance of deposits in financial institutions increased by $1.0 billion and the average balance of investment securities increased by $781.1 million in the fourth quarter of 2020.

The cost of average total deposits decreased to 0.14% for the fourth quarter of 2020 from 0.17% for the third quarter of 2020 due mainly to the repricing of maturing brokered time deposits.

Noninterest income increased by $1.6 million to $39.9 million for the fourth quarter of 2020 compared to $38.3 million for the third quarter of 2020 due primarily to an increase of $6.8 million in warrant income attributable to higher gains from exercised warrants, and an increase of $1.6 million in gain on sale of loans and leases, offset partially by decreases of $5.3 million in gain on sale of securities and $1.9 million in dividends and gains on equity investments. The increase in the gain on sale of loans and leases resulted from the sales of $119.9 million of loans for a gain of $1.7 million in the fourth quarter of 2020 compared to sales of $3.0 million for a gain of $35,000 in the third quarter of 2020. The decrease in the gain on sale of securities resulted from minimal sales in the fourth quarter of 2020 compared to sales of $17.0 million of securities for a gain of $5.3 million in the third quarter of 2020. The decrease in dividends and gains on equity investments was due primarily to lower net fair value gains on equity investments still held, offset partially by higher income from distributions on equity investments.

Noninterest expense increased by $2.3 million to $135.7 million for the fourth quarter of 2020 compared to $133.4 million for the third quarter of 2020 attributable primarily to increases of $2.1 million in other professional services, $1.1 million in insurance and assessments, $1.1 million in acquisition, integration and reorganization costs, and $1.1 million in other expense, offset partially by a decrease of $2.0 million in compensation expense. The increase in other professional services was due mainly to higher consulting expense. The increase in insurance and assessments expense was due to an increase in FDIC assessment expense. The increase in acquisition, integration and reorganization costs was due to advisory services. The increase in other expense was due primarily to an increase in franchise taxes. The decrease in compensation expense was due mainly to lower bonus accruals and lower stock compensation expense.

(1)    Includes $167.1 million, $173.4 million, $168.9 million, $180.1 million, and $152.9 million at December 31, 2020, 2019, 2018, 2017, and 2016 of land acquisition and development loans.

71

Our loan portfolio segments of real estate mortgage loans, real estate construction and land loans, and commercial loans comprised 41%, 18%, and 39% of our total loans and leases held for investment at December 31, 2020, compared to 42%, 15%, and 41% at December 31, 2019, respectively.

The changes during 2020 in the portfolio classes comprising these portfolio segments reflected the following:

•Commercial real estate mortgage loans decreased by 3% to $4.1 billion or 21% of total loans and leases held for investment at December 31, 2020 from $4.2 billion or 22% at December 31, 2019. The lower balance and composition ratio was attributable primarily to the balance of healthcare real estate loans declining by 47% to $177.4 million at December 31, 2020 from $334.1 million at December 31, 2019. In October 2019, we stopped actively originating healthcare real estate loans.

•Income producing and other residential real estate mortgage loans increased slightly by 1% to $3.80 billion or 20% of total loans and leases held for investment at December 31, 2020 from $3.77 billion or 20% at December 31, 2019.

•Commercial real estate construction and land loans increased by 3% to $1.12 billion or 6% of total loans and leases held for investment at December 31, 2020 from $1.08 billion or 6% at December 31, 2019. The net increase in the balance was attributable to increases in balances on existing and new loans as disbursements occur during construction that are offset by repayments of loans stemming from our loans being refinanced or the properties securing our loans being sold.

•Residential real estate construction and land loans increased by 36% to $2.2 billion or 12% of total loans and leases held for investment at December 31, 2020 from $1.7 billion or 9% at December 31, 2019. The higher balance and composition ratio was attributable to increases in balances on existing and new loans as disbursements occur during construction which are offset by repayments of loans stemming from our loans being refinanced or the properties securing our loans being sold.

•Asset-based loans and leases decreased by 9% to $3.4 billion or 18% of total loans and leases held for investment at December 31, 2020 from $3.7 billion or 20% at December 31, 2019. The lower balance and composition ratio was due primarily to payments and payoffs exceeding newly originated loans and leases in equipment finance and other asset based loans. Equipment finance loans and leases decreased to $700.0 million at December 31, 2020 from $852.3 million at December 31, 2019, and other asset-based loans decreased to $194.5 million at December 31, 2020 from $309.9 million at December 31, 2019.

•Venture capital loans decreased by 22% to $1.7 billion or 9% of total loans and leases held for investment at December 31, 2020 from $2.2 billion or 12% at December 31, 2019. The lower balance and composition ratio was attributable to lower equity fund loans and venture lending loans to venture-backed companies. Equity fund loans decreased to $1.0 billion at December 31, 2020 from $1.2 billion at December 31, 2019. Venture lending loans decreased to $665.8 million at December 31, 2020 from $980.2 million at December 31, 2019.

•Other commercial loans increased by 34% to $2.4 billion or 12% of total loans and leases held for investment at December 31, 2020 from $1.8 billion or 9% at December 31, 2019. The higher balance and composition ratio was attributable primarily to Paycheck Protection Program ("PPP") loans originated in 2020, offset partially by lower security monitoring loans, which decreased by 47% to $329.3 million at December 31, 2020 from $619.3 million at December 31, 2019, and to the declining balance of secured business loans, which decreased to $430.3 million at December 31, 2020 from $583.3 million at December 31, 2019. In October 2019, we stopped originating security monitoring loans.

At December 31, 2020 and 2019, 62% and 61% of our real estate loans were collateralized by property located in California because our full-service branches and our community banking activities are primarily located in California. The increase in real estate loans in Colorado reflects the growth from opening our Denver branch in November 2019.

At December 31, 2020, we had $5.3 billion of loans and leases held for investment due to mature over the next twelve months. For any of these loans and leases held for investment, in the event that we provide a concession through a refinance or modification that we would not ordinarily consider in order to protect as much of our investment as possible, such loans may be considered TDRs even though the loans have performed in accordance with their contractual terms. The circumstances 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 a contractual loan renewal or loan extension constitutes a TDR. Higher levels of TDRs may result in increases in classified loans and credit loss provisions.

The following table presents the interest rate profile of loans and leases held for investment, net of deferred fees, due after one year as of the date indicated:

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 the amortized cost basis of loans and leases, while the reserve for unfunded loan commitments is included within "Accrued interest payable and other liabilities" on the consolidated balance sheets. The amortized cost basis of loans and leases does not include accrued interest receivable, which is included in "Other assets" on the consolidated balance sheets. The "Provision for credit losses" on the consolidated statement of earnings (loss) is a combination of the provision for loan and lease losses and the provision for unfunded loan commitments.

Under the CECL methodology, expected credit losses reflect losses over the remaining contractual life of an asset, considering the effect of prepayments and available information about the collectability of cash flows, including information about relevant historical experience, current conditions, and reasonable and supportable forecasts of future events and circumstances. Thus, the CECL methodology incorporates a broad range of information in developing credit loss estimates.

For further information regarding the calculation of the allowance for credit losses on loans and leases held for investment using the CECL methodology effective January 1, 2020, see Note 1. Nature of Operations and Summary of Significant Accounting Policies - (a) Accounting Standards Adopted in 2020 and (i) Allowance for Credit Losses on Loans and Leases Held for Investment of the Notes to Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data."

In calculating our allowance for credit losses, we continued to consider the impacts of the COVID-19 pandemic on our estimation of expected credit losses given the changes in economic forecasts and assumptions along with the uncertainty related to the severity and duration of the economic consequences of the COVID-19 pandemic. Our methodology and framework along with the 4-quarter reasonable and supportable forecast period and 2-quarter reversion period have remained consistent since the implementation of CECL on January 1, 2020. Certain management assumptions are reassessed every quarter based on current expectations for credit losses, while other assumptions are assessed and updated on at least an annual basis. In the second quarter of 2020, we performed the annual update to our estimated prepayment rates and expected future utilization rates for the reserve for unfunded commitments, while during the third quarter of 2020, we performed the annual update to our PD econometric regression models.

75

In the fourth quarter of 2020, we used the Moody’s Slower-Trend Growth Scenario Forecast dated December 9, 2020 as the single scenario economic forecast for our quantitative component. Although we generally prefer the Moody's Consensus Scenario Forecast given that it reflects the aggregated views of various economic forecast surveys, we viewed the Moody's Consensus Scenario Forecast dated December 9, 2020 to be more optimistic than management's view based on more recent economic data received during December 2020 including a higher increase in jobless claims, lower than expected retail sales, more business disruptions from an increase in COVID-19 infections, extension of stay-at-home orders particularly in California, slower than anticipated distribution of vaccinations, reports of new variants of the COVID-19 virus, a federal aid bill that may provide less direct relief to consumers and state/local governments, and the continued uncertainty with respect to the economy caused by the ongoing COVID-19 pandemic. Management views of a slower path to economic recovery were more consistent with the Moody's Slower-Trend Growth Scenario Forecast and was deemed to be reasonable and supportable based on current conditions.

In the second and third quarters of 2020, we used the Moody’s Consensus Scenario Forecast dated June 11, 2020 and September 11, 2020, respectively, for our quantitative component, unlike the first quarter of 2020 when we used the Moody’s Baseline Forecast dated March 27, 2020, as the Consensus Scenario Forecast at that time was considered stale due to the fact it was dated March 12, 2020 and did not reflect the COVID-19 pandemic and rapidly changing environment. For the first and second quarters of 2020, we made additional adjustments to the quantitative calculation due to regression model limitations caused by the sudden and unprecedented changes in macroeconomic variables and for imprecision inherent in the economic forecasts. In the third quarter of 2020, as part of the planned annual update of the PD regression models, we recalibrated the models in consideration of known model limitations to improve performance when applying highly volatile economic forecasts. The recalibration of models included expanding the number of macroeconomic variables and the variable transformations used to correlate to historical credit performance. As a result of the updated PD regression models, adjustments that were made to the quantitative calculation in the first and second quarters were not necessary in the third and fourth quarters.

As part of our allowance for credit losses methodology, we consistently incorporate the use of qualitative factors in determining the overall allowance for credit losses to capture risks that may not be adequately reflected in our quantitative models. In the fourth quarter of 2020, we added qualitative reserves related to collateral dependency risk for hotel real estate and security monitoring loans. For hotel real estate loans, the qualitative adjustment reflects projected market value declines resulting from significant reductions in both business and leisure travel due to the COVID-19 pandemic, which are not adequately reflected in the quantitative reserve based on historical experience. For security monitoring loans, the impact of newer technologies on the valuation of traditional security monitoring services was assessed as a qualitative adjustment.

The use of different economic forecasts, whether based on different scenarios, the use of multiple or single scenarios, or updated economic forecasts and scenarios, can change the outcome of the calculations. In addition to the economic forecasts, there are numerous components and assumptions that are integral to the overall estimation of allowance for credit losses. As part of our allowance for credit losses process, sensitivity analyses are performed to assess the impact of how changing certain assumptions could impact the estimated allowance for credit losses. At times, these analyses can provide information to further assist management in making decisions on certain assumptions. However, changing one assumption and not reassessing other assumptions used in the quantitative or qualitative process could yield results that are not reasonable or appropriate, hence all assumptions and information must be considered. From a sensitivity analysis perspective, changing key assumptions such as the macro-economic variable inputs from the economic forecasts, the reasonable and supportable forecast period, prepayment rates, loan segmentation, historical loss factors and/or periods, among others, would all change the outcome of the quantitative components of the allowance for credit losses. Those results would then need to be assessed from a qualitative perspective potentially requiring further adjustments to the qualitative component to arrive at a reasonable and appropriate allowance for credit losses.

The determination of the allowance for credit losses is complex and highly dependent on numerous models, assumptions, and judgments made by management. Management's current expectation for credit losses as quantified in the allowance for credit losses considers the impact of assumptions and is reflective of historical credit experience, economic forecasts viewed to be reasonable and supportable, current loan and lease composition, and relative credit risks known as of the balance sheet date.

76

Management believes the allowance for credit losses is appropriate for the current expected credit losses in our loan and lease portfolio and associated unfunded commitments, and the credit risk ratings and inherent loss rates currently assigned are reasonable and appropriate as of the reporting date. 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 consolidated financial statements.

(1) Charge-offs related to 2020, 2019, and 2018 are for total loans and leases. Charge-offs related to 2017 and 2016 are for Non-PCI loans and leases.

Commercial real estate mortgage gross charge-offs increased to $10.2 million for the year ended December 31, 2020 from $0.9 million for the year ended December 31, 2019. The 2020 amount included $8.2 million gross of charge-offs related to two retail properties that were adversely affected by pandemic-related business closures.

Asset-based gross charge-offs decreased to $11.8 million for the year ended December 31, 2020 from $12.0 million for the year ended December 31, 2019. The 2020 amount included an $11.8 million gross charge-off in the equipment finance subclass related to a single loan. The 2019 amount included an $11.8 million gross charge-off in the other asset-based subclass related to a single loan.

79

Venture capital gross charge-offs decreased to $6.8 million for the year ended December 31, 2020 from $9.4 million for the year ended December 31, 2019. The 2020 amount included one loan for $6.5 million. The 2020 lower venture capital gross charge-off experience is attributable to improvements made in venture capital loan underwriting and credit administration since 2018.

Other commercial gross charge-offs increased to $63.5 million for the year ended December 31, 2020 from $9.1 million for the year ended December 31, 2019. The 2020 amount includes $59.6 million for five security monitoring loans, representing 64% of total gross charge-offs for 2020. In October 2019, we decided to no longer originate new security monitoring loans. Our security monitoring loans decreased by 47% to $329.3 million at December 31, 2020 from $619.3 million at December 31, 2019.

(1) Amounts and ratios related to 2020, 2019, and 2018 are for total loans and leases. Amounts and ratios related to 2017 and 2016 are for Non-PCI loans and leases.

The allowance for loan and lease losses attributable to real estate mortgage loans was $138.3 million and $44.6 million at December 31, 2020 and 2019. As ratios to real estate mortgage loans at those dates, these percentages were 1.75% and 0.56%. The increase is attributable to the adoption of CECL in 2020 which requires reserves for expected losses over the estimated lives of the loans and leases and the COVID-19 pandemic impact on our estimates of expected losses.

The allowance for loan and lease losses attributable to real estate construction and land loans was $78.4 million and $30.5 million at December 31, 2020 and 2019. As ratios to real estate construction and land loans at those dates, these percentages were 2.33% and 1.12%. The increase is attributable to the adoption of CECL in 2020 which requires reserves for expected losses over the estimated lives of the loans and leases and the COVID-19 pandemic impact on our estimates of expected losses.

The allowance for loan and lease losses attributable to commercial loans and leases was $126.4 million and $61.5 million at December 31, 2020 and 2019. As ratios to commercial loans and leases at those dates, these percentages were 1.68% and 0.80%. The increase is attributable to the adoption of CECL in 2020 which requires reserves for expected losses over the estimated lives of the loans and leases and the COVID-19 pandemic impact on our estimates of expected losses.

During 2020, total deposits increased by $5.7 billion, or 30%, to $24.9 billion at December 31, 2020, due primarily to increases of $6.1 billion in core deposits and $653.1 million in non-core non-maturity deposits, offset partially by a decrease in time deposits of $1.0 billion. The increase in core deposits was due primarily to capital market activities by our venture banking clients, which saw venture banking deposits increase by $3.9 billion to $11.0 billion at December 31, 2020, and to PPP loan proceeds being deposited into customers' accounts. The increase in core deposits by component was due to increases of $2.0 billion in noninterest-bearing demand deposits, $2.2 billion in interest checking deposits, $1.8 billion in money market deposits, and $63.2 million in savings deposits. At December 31, 2020, core deposits totaled $22.3 billion, or 89% of total deposits, including $9.2 billion of noninterest-bearing demand deposits, or 37% of total deposits. Our deposit base is also diversified by client type. As of December 31, 2020, no individual depositor represented more than 4.3% of our total deposits, and our top ten depositors represented 13.4% of our total deposits.

Borrowings and Subordinated Debentures

The Bank has various available lines of credit. These include the ability to borrow funds from time to time on a long‑term, short‑term, or overnight basis from the FHLB, the FRBSF, or other financial institutions. The maximum amount that the Bank could borrow under its secured credit line with the FHLB at December 31, 2020 was $3.3 billion, of which all but $5.0 million was available on that date. The maximum amount that the Bank could borrow under its secured credit line with the FRBSF at December 31, 2020 was $1.4 billion, all of which was available on that date. The FHLB secured credit line was collateralized by a blanket lien on $5.6 billion of certain qualifying loans. The FRBSF secured credit line was collateralized by liens on $1.9 billion of qualifying loans. In addition to its secured lines of credit, the Bank also maintains unsecured lines of credit for the borrowing of overnight funds, subject to availability, of $112.0 million with the FHLB and $180.0 million in the aggregate with several correspondent banks. As of December 31, 2020, there was no balance outstanding related to these unsecured lines 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, 2020, the Bank had no outstanding borrowings through the AFX.

Total loans and leases held for investment, net of deferred fees	$	19,083,377	$	18,846,872	$	17,957,713

Classified and special mention loans and leases fluctuate from period to period as a result of loan repayments and downgrades or upgrades from our ongoing active portfolio management. Both special mention and classified loans had significant increases in 2020. A significant majority of these increases occurred in the first quarter of 2020 as we proactively downgraded loans and leases due to the uncertainty surrounding the long-term economic effects of the COVID-19 pandemic. A high percentage of these downgrades were in industries more acutely impacted by the COVID-19 pandemic such as hotels, commercial aviation, and retail.

During 2020, classified loans and leases increased by $89.4 million to $265.3 million at December 31, 2020 due mainly to increases of $58.0 million in commercial real estate mortgage classified loans, $42.2 million in commercial real estate construction and land classified loans, and $22.3 million in other commercial classified loans, offset partially by a decrease of $28.8 million in venture capital classified loans. Classified loans and leases peaked in the second quarter of 2020 at $293.2 million.

87

During 2020, special mention loans and leases increased by $398.3 million to $721.3 million at December 31, 2020 due primarily to increases of $232.4 million in commercial real estate mortgage special mention loans, $114.4 million in asset-based special mention loans and leases, $107.6 million in commercial real estate construction and land special mention loans, $59.7 million in income producing and other residential special mention loans, and $43.3 million in venture capital special mention loans, offset partially by a decrease of $159.9 million in other commercial special mention loans. Special mention loans and leases peaked in the first quarter of 2020 at $898.7 million.

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, 2020, 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%.

Basel III currently requires all banking organizations to maintain a 2.50% 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. Effective January 1, 2019, the common equity Tier 1, Tier 1, and total capital ratio minimums inclusive of the capital conservation buffer were 7.00%, 8.50%, and 10.50%. At December 31, 2020, the Company and Bank were in compliance with the capital conservation buffer requirements.

The Company and Bank elected the CECL 5-year regulatory transition guidance for calculating regulatory capital ratios and the December 31, 2020 ratios include this election. This regulatory guidance allows an entity to add back to capital 100% of the capital impact from the day one CECL transition adjustment and 25% of subsequent increases to the allowance for credit losses through December 31, 2022. This cumulative amount will then be phased out of regulatory capital over the next three years from 2023 to 2025. The add-back as of December 31, 2020 ranged from 22 basis points to 27 basis points for the capital ratios below.

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:

Subordinated Debentures

We issued or assumed through mergers subordinated debentures to trusts that were established by us or entities we acquired, which, in turn, issued trust preferred securities. The carrying value of subordinated debentures totaled $465.8 million at December 31, 2020. At December 31, 2020, none of the trust preferred securities were included in the Company's Tier I capital under the phase-out limitations of Basel III, and $451.8 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."

Dividends on Common Stock and Interest on Subordinated Debentures

As a bank holding company, PacWest is required to notify and receive approval from 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 on subordinated debentures are considered dividend payments under FRB regulations. 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. Since the impact of the goodwill impairment charge on net earnings in the first quarter of 2020, we are required to receive approval from the FRB prior to declaring a dividend until such time the applicable regulations no longer require such approval. The FRB approved our first quarter 2021 dividend, which is scheduled to be paid on March 10, 2021.

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.

90

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 $3.3 billion at December 31, 2020, of which all but $5.0 million was available on that date. The FHLB secured credit line was collateralized by a blanket lien on $5.6 billion of certain qualifying loans. The Bank also had secured borrowing capacity with the FRBSF of $1.4 billion at December 31, 2020, all of which was available on that date. The FRBSF secured credit line was collateralized by liens on $1.9 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 $112.0 million with the FHLB and $180.0 million in the aggregate with several correspondent banks. As of December 31, 2020, there was no balance outstanding related to these unsecured lines 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, 2020, the Bank had borrowed nothing through the AFX.

The following tables provide a summary of the Bank’s primary and secondary liquidity levels as of the dates indicated:

	December 31,
Primary Liquidity - On-Balance Sheet	2020			2019			2018
	(Dollars in thousands)
Cash and due from banks	$	150,464		$	172,585		$	175,830

	(In thousands)
Total secured borrowing capacity with the FHLB	$	3,330,715	$	4,229,788	$	3,746,970
Less: secured advances outstanding	(5,000)		(1,318,000)		(1,040,000)
Available secured borrowing capacity with the FHLB	3,325,715		2,911,788		2,706,970
Available secured borrowing capacity with the FRBSF	1,409,452		1,988,028		2,003,269
Total secondary liquidity	$	4,735,167	$	4,899,816	$	4,710,239

During 2020, the Company's primary liquidity increased by $4.0 billion to $7.9 billion at December 31, 2020 due mainly to a $2.5 billion increase in interest-earning deposits in financial institutions, a $1.4 billion increase in securities available-for-sale, and a $36.9 million decrease in pledged securities. During 2020, the Company's secondary liquidity decreased by $164.6 million to $4.7 billion at December 31, 2020 due mostly to a $578.6 million decrease in available borrowing capacity on the secured credit line with the FRBSF, offset partially by a $413.9 million increase in available secured borrowing capacity with the FHLB. The $413.9 million increase in available secured borrowing capacity with the FHLB resulted primarily from a $1.3 billion decrease in the amount borrowed from the secured borrowing line with the FHLB, offset partially by an $899.1 million decrease in the borrowing capacity related to pledged loans.

91

In addition to our primary liquidity, we generate liquidity from cash flows from our loan and securities portfolios and from our large base of core deposits, defined as noninterest-bearing demand, interest checking, savings, and non-brokered money market accounts. At December 31, 2020, core deposits totaled $22.3 billion and represented 89% of the Company's total deposits. 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.

The Bank maintains adequate levels of liquidity to address potential cash outflows from fluctuating deposit balances, draws on unfunded loan commitments, anticipated loan production, scheduled maturities of borrowed funds, and other causes of cash flow volatility.

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, 2020, brokered deposits totaled $1.3 billion, consisting primarily of $1.1 billion of non-maturity brokered accounts and $195.7 million of brokered time deposits. At December 31, 2019, brokered deposits totaled $1.7 billion, consisting mainly of $1.2 billion of brokered time deposits and $496.4 million of non-maturity brokered accounts.

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. At December 31, 2020, the Bank was in compliance with all 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. PacWest's 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. PacWest's ability to pay dividends is also subject to the restrictions set forth in Delaware law, by the FRB, and by certain covenants contained in our subordinated debentures. Approval by the FRB is required prior to our declaring and paying a cash dividend during any period in which our quarterly and/or cumulative twelve-month net earnings are insufficient to fund the dividend amount, among other requirements. PacWest 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. Due to the impact of the goodwill impairment charge on net earnings in the first quarter of 2020, we are now required to receive approval from the FRB, as described above, prior to declaring a dividend.

Dividends paid by California state-chartered banks are regulated by the FDIC for non-member banks and the DFPI under their general supervisory authority. The Bank may declare a dividend without the approval of the DFPI 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. The Bank had a net loss of $256.7 million during the three fiscal years of 2020, 2019, and 2018, compared to dividends of $1.3 billion paid by the Bank during that same period. During the year ended December 31, 2020, PacWest received $258.0 million in dividends from the Bank. Since the Bank had an accumulated deficit of $2.0 billion at December 31, 2020, for the foreseeable future any dividends from the Bank to PacWest will continue to require DFPI and FDIC approval consistent with what has been required since 2008 when the Bank first had an accumulated deficit triggered by goodwill impairment write-downs during the financial crisis of 2007-2008.

At December 31, 2020, PacWest had $127.8 million in cash and cash equivalents, of which substantially all is on deposit at the Bank. We believe this amount of cash, along with anticipated future dividends from the Bank, will be sufficient to fund the holding company’s cash flow needs over the next 12 months.

92

Stock Repurchase Programs

In February 2020, we repurchased 1,953,711 shares of common stock for a total amount of $70.0 million at an average price of $35.83 under the former Stock Repurchase Program. All shares repurchased under the former Stock Repurchase Program were retired upon settlement.

On February 12, 2020, PacWest's Board authorized a new Stock Repurchase Program to purchase shares of its common stock for an aggregate purchase price not to exceed $200 million. The new Stock Repurchase Program is effective from February 29, 2020 and terminates on February 28, 2021. On April 21, 2020, stock repurchases under the new Stock Repurchase Program were suspended indefinitely. No shares have been repurchased under the new Stock Repurchase Program and the entire $200 million is remaining at December 31, 2020.

_______________________________________ 

(1)    Excludes purchase accounting fair value adjustments.

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

Operating lease obligations, time deposits, and debt obligations are discussed in Note 6. 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.

93

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, 2020, our loan commitments and standby letters of credit were $7.6 billion and $337.3 million. The loan commitments, a portion of which will eventually result in funded loans, increase our profitability through net interest income when drawn and unused commitment fees prior to being 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 13. Commitments and Contingencies of the Notes to Consolidated Financial Statements contained in “Item 8. Financial Statements and Supplementary Data.”

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk - Foreign Currency Exchange

We enter into foreign exchange contracts with our clients and counterparty banks primarily for the purpose of offsetting or hedging clients' 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 derivatives that hedge those exposures. As of December 31, 2020, the U.S. Dollar notional amounts of loans receivable and subordinated debentures payable denominated in foreign currencies were $43.4 million and $31.5 million, and the U.S. Dollar notional amounts of derivatives outstanding to hedge these foreign currency exposures were $44.6 million and $28.5 million. We recognized foreign currency translation net gains of $3,000, $150,000, and $299,000 for the years ended December 31, 2020, 2019, and 2018, respectively.

Asset/Liability Management and Interest Rate Sensitivity

Interest Rate Risk

We measure our IRR position on a monthly 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, 2020, the results of which are presented below. Our NII simulation and MVE model indicate that our balance sheet is asset-sensitive. An asset-sensitive profile would suggest that a sudden sustained increase in rates would result in an increase in our estimated 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, 2020. 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 or changes in the product mix of 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, 2020. In order to arrive at the base case, we extend our balance sheet at December 31, 2020 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, 2020. Based on such repricing, we calculate an estimated NII and NIM for each rate scenario.

95

The NII simulation model is dependent upon numerous assumptions. For example, the majority of our loans are variable rate that are assumed to reprice in accordance with their contractual terms. Some loans and investment securities include the opportunity of prepayment (embedded options) and the simulation model uses prepayment assumptions to estimate these accelerated cash flows 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, 2020 assumes interest-bearing deposits reprice at 29% of the change in market rates in a rising interest rate scenario, depending on the amount of the rate change (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. Additionally, we assume that all market interest rates have an interest rate floor of 0%. Changes that could vary significantly from our assumptions include loan and deposit growth or contraction, loan and deposit pricing, changes in the mix of 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 movements in interest rates of 100, 200, and 300 basis points and sustained parallel downward movements in interest rates of 25, 50, and 100 basis points as of the date indicated:

	Forecasted			Forecasted	Forecasted
	Net Interest		Percentage	Net Interest	Net Interest
	Income		Change	Margin	Margin Change
December 31, 2020	(Tax Equivalent)		From Base	(Tax Equivalent)	From Base
	(Dollars in millions)
Interest Rate Scenario:
Up 300 basis points	$	1,236.9	20.8%	4.67%	0.80%
Up 200 basis points	$	1,147.9	12.1%	4.33%	0.46%
Up 100 basis points	$	1,072.8	4.7%	4.05%	0.18%
BASE CASE	$	1,024.2	—	3.87%	—
Down 25 basis points	$	1,019.2	(0.5)%	3.81%	(0.06)%
Down 50 basis points	$	1,014.6	(0.9)%	3.83%	(0.04)%
Down 100 basis points	$	1,013.6	(1.0)%	3.83%	(0.04)%

During 2020, total base case year 1 tax equivalent NII increased by $62.4 million to $1.02 billion at December 31, 2020 and the base case tax equivalent NIM decreased to 3.87% from 4.15%. The increase in year 1 NII compared to December 31, 2019 is due to lower cost of funds, offset partially by lower yield on earning assets. The decrease in NIM was due almost entirely to the year-over-year shift in the earning assets mix in the static balance sheet, as the balance of low yielding interest-earning deposits in financial institutions increased by $2.5 billion from the large increase in core deposits during 2020. The core deposits increase related primarily to the strong deposit growth from our venture banking clients.

In addition to parallel interest rate shock scenarios, we also model various alternative rate vectors. The most favorable alternate rate vector that we model is the “Bear Flattener” scenario, when short-term rates increase faster than long-term rates. In the “Bear Flattener” scenario, Year 1 tax equivalent NII increases by 1.4%. Because of the low level of market interest rates and the assumption that market rates contain a 0% floor, the ad hoc scenarios that assume decreasing interest rates do not differ materially from the base case scenario.

96

At December 31, 2020, we had $19.2 billion of total loans that included $10.4 billion with variable interest rate terms (excluding hybrid loans discussed below). Of the variable interest rate loans, $8.7 billion, or 84%, contained interest rate floor provisions, which included $8.6 billion of loans with "in-the-money" floors, meaning the loan coupon will not adjust down if there are future decreases to the index interest rate. The following table summarizes the estimated balance of loans with "in-the-money" floors for the indicated increases in interest rates:

December 31, 2020
	Total Amount of
	Loans With
Basis Points of	"In-the-Money"
Rate Increases	Loan Floors
(Dollars in millions)
50 bps	$6,362
100 bps	$4,330
150 bps	$2,811
200 bps	$1,028
250 bps	$145

At December 31, 2020, we also had $4.0 billion of variable-rate hybrid loans that 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 $541 million, $1.1 billion, and $1.7 billion in the next one, two, and three years.

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 business processes impacted relate primarily to our variable-rate loans and our subordinated debentures, both of which are indexed to LIBOR. For further information see Item 1A. Risk Factors.

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 in market interest rates of 100, 200, and 300 basis points and sustained decrease in market interest rates of 25, 50, and 100 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, 2020.

97

The following table shows the projected change in the market value of equity for the rate scenarios presented as of the date indicated:

							Ratio of
	Projected		Dollar		Percentage	Percentage	Projected
	Market Value		Change		Change	of Total	Market Value
December 31, 2020	of Equity		From Base		From Base	Assets	to Book Value
	(Dollars in millions)
Interest Rate Scenario:
Up 300 basis points	$	6,510.3	$	780.5	13.6%	22.1%	181.1%
Up 200 basis points	$	6,259.2	$	529.4	9.2%	21.2%	174.1%
Up 100 basis points	$	5,992.0	$	262.2	4.6%	20.3%	166.7%
BASE CASE	$	5,729.8	$	—	—	19.4%	159.4%
Down 25 basis points	$	5,644.9	$	(84.9)	(1.5)%	19.1%	157.0%
Down 50 basis points	$	5,525.4	$	(204.4)	(3.6)%	18.7%	153.7%
Down 100 basis points	$	5,300.6	$	(429.2)	(7.5)%	18.0%	147.4%

During 2020, total base case projected market value of equity decreased by $1.6 billion to $5.7 billion at December 31, 2020. This decrease in base case projected MVE was due primarily to: (1) a $1.36 billion decrease in the book value of stockholders' equity due mainly to a $1.24 billion net loss attributable primarily to a $1.47 billion goodwill impairment charge, $70.0 million of common stock repurchased under the Stock Repurchase Program, and $159.7 million of cash dividends paid, offset partially by a $93.9 million increase in accumulated other comprehensive income; and (2) a $496.6 million increase in the mark-to-market adjustment for total deposits from the lower market interest rates used for the deposit valuation; offset partially by (3) a $224.1 million increase in the mark-to-market adjustment for loans and leases due to the impact of lower credit spreads used for calculating the valuation.

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

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

As of December 31, 2020, 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, 2020, 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, 2020. The report, which expresses an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2020, is included in this Item under the heading “Report of Independent Registered Public Accounting Firm.”

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, 2020 and 2019, the related consolidated statements of earnings (loss), comprehensive income (loss), changes in stockholders’ equity, and cash flows for each of the years in the three‑year period ended December 31, 2020, 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, 2020, 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, 2020 and 2019, and the results of its operations and its cash flows for each of the years in the three‑year period ended December 31, 2020, 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, 2020 based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Change in Accounting Principle

As discussed in Note 1 to the consolidated financial statements, the Company has changed its method of accounting for the recognition and measurement of credit losses as of January 1, 2020 due to the adoption of ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.”

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.

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.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Assessment of the allowance for credit losses for loans and leases collectively evaluated

As discussed in Note 1 to the consolidated financial statements, the Company’s allowance for credit losses for loans and leases collectively evaluated is the combination of an allowance for loan and lease losses collectively evaluated (reserve on pooled loans and leases) and the reserve for unfunded loan commitments (collective ACL). The Company adopted ASU No. 2016-13, Financial Instruments— Credit Losses (ASC Topic 326) as of January 1, 2020. The total allowance for credit losses as of January 1, 2020 was $182.0 million, of which $175.8 million related to the collective ACL (the January 1, 2020 collective ACL). As discussed in Note 1 and 4 to the consolidated financial statements, the Company’s total allowance for credit losses as of December 31, 2020 was $433.8 million, of which $430.1 million related to the collective ACL (the December 31, 2020 collective ACL). The collective ACL is measured with the current expected credit loss (CECL) approach for financial instruments measured at amortized cost and other commitments to extend credit which share similar risk characteristics and reflects losses over the remaining contractual life of an asset, considering the effect of prepayments and available information about the collectability of cash flows, including information about relevant historical loss experience, current conditions, and reasonable and supportable forecasts of future events and circumstances. The Company’s CECL methodology for the reserve on pooled loans and leases component includes both quantitative and qualitative loss factors which are applied to the population of loans and leases and assessed at a pool level. The Company estimates the probability of default (PD) during the reasonable and supportable period using econometric regression models developed to correlate macroeconomic variables to historical credit performance. The loans and unfunded commitments are grouped into loss given default (LGD) pools based on portfolio classes that share similar collateral risk characteristics. LGD rates are computed based on the net charge-offs recognized divided by the exposure at default (EAD) of defaulted loans. The Company estimates the reserve for unfunded loan commitments using the same PD, LGD, and prepayment rates as used for the reserve on pooled loans and leases. The reserve for unfunded loan commitments is computed using expected future utilization rates of the unfunded commitments during the contractual life of the commitments based on historical usage of unfunded commitments by loan pool. For the reasonable and supportable forecast period, future macroeconomic events and circumstances are estimated using a single scenario economic forecast that is consistent with the Company’s current expectations for the loan pools. The EAD is multiplied by the PD and LGD rates to calculate expected losses through the end of the forecast period. The Company then reverts on a straight-line basis from the PD, LGD and prepayment rates used during the reasonable and supportable period to the Company’s historical PD, LGD and prepayment experience. The qualitative portion of the reserve on pooled loans and leases represents the Company’s judgment of additional considerations to account for internal and external risk factors that are not adequately measured in the quantitative reserve, including consideration of idiosyncratic risk factors,

102

conditions that may not be reflected in quantitatively derived results, or other relevant factors to ensure the collective ACL reflects the Company’s best estimate of current expected credit losses.

We identified the assessment of the January 1, 2020 collective ACL and the December 31, 2020 collective ACL as a critical audit matter. A high degree of audit effort, including specialized skills and knowledge, and subjective and complex auditor judgment was involved in the assessment. Specifically, the assessment encompassed the evaluation of the collective ACL methodology, including the methods and models used to estimate the PD, LGD, prepayments and their significant assumptions, including the pooling of loans and leases which share similar risk characteristics, the economic forecast and macroeconomic events and circumstances, the reasonable and supportable forecast period, the reversion to the Company’s historical PD, LGD and prepayment experience for the remaining contractual life of the loans and leases, internal risk ratings for commercial loans, and the qualitative loss factors and their significant assumptions, including the idiosyncratic risk factors and portfolio concentrations. The assessment included an evaluation of the conceptual soundness of the PD, LGD, and prepayment models. The assessment also encompassed the determination of expected future utilization rates on unfunded loan commitments utilized in the reserve for unfunded loan commitments. In addition, auditor judgment was required to evaluate the sufficiency of audit evidence obtained.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company’s measurement of the collective ACL estimates, including controls over the:

•development and approval of the collective ACL methodology

•development of the PD, LGD and prepayment models

•identification and determination of the significant assumptions used in the PD, LGD and prepayment models used to calculate the collective ACL

•development of the qualitative loss factors, including the significant assumptions used in the measurement of the qualitative factors

•development of the expected future utilization rates of unfunded loan commitments

•analysis of the collective ACL results, trends and ratios.

We evaluated the Company’s process to develop the January 1, 2020 collective ACL and the December 31, 2020 collective ACL estimates by testing certain sources of data, factors, and assumptions that the Company used, and considered the relevance and reliability of such data, factors and assumptions. In addition, we involved credit risk professionals with specialized skills and knowledge, who assisted in the following:

•evaluating the collective ACL methodology for compliance with U.S. generally accepted accounting principles

evaluating judgments made by the Company relative to the development and performance of the PD, LGD, and prepayment models by comparing them to relevant Company-specific metrics and trends and the applicable industry and regulatory practices

•assessing the conceptual soundness and performance of the PD, LGD and prepayment models by inspecting the model documentation to determine whether the models are suitable for their intended use

•evaluating the selection of the economic forecast and underlying assumptions by comparing them to relevant Company-specific metrics and trends and the applicable industry and regulatory practices

•evaluating the economic forecast and macroeconomic events and circumstances through comparison to publicly available forecasts

•evaluating the length of the historical observation period, reasonable and supportable forecast period, and reversion period by comparing them to specific portfolio risk characteristics and trends

•determining whether the loan and lease portfolio is pooled by similar risk characteristics by comparing to the Company’s business environment and relevant industry practices

•evaluating individual internal risk ratings for a selection of commercial loans by evaluating the financial performance of the borrower, sources of repayment, and any relevant guarantees or underlying collateral

•evaluating the methodology used to develop the qualitative loss factors and their significant assumptions, and the effect of those factors on the collective ACL compared with relevant credit risk factors and consistency with credit trends and identified limitations of the underlying quantitative models

103

•evaluating the methodology of the expected future utilization rates of unfunded loan commitments by comparing them to relevant Company-specific metrics and trends.

We also assessed the sufficiency of the audit evidence obtained related to the Company’s January 1, 2020 collective ACL and the December 31, 2020 collective ACL by evaluating the:

•cumulative results of the audit procedures

•qualitative aspects of the Company’s accounting practices

•potential bias in the accounting estimates.

Assessment of the valuation of goodwill

As discussed in Notes 1 and 7 to the consolidated financial statements, the goodwill balance as of December 31, 2020 was $1.1 billion, of which all was related to the Company’s one reportable segment. The Company performs goodwill impairment testing on an annual basis and whenever events or changes in circumstances indicate that the carrying value of a reporting unit likely exceeds its fair value. During the quarter ended March 31, 2020, due to the decline in economic conditions triggered by the COVID-19 pandemic which caused a significant decline in stock market valuations in March 2020, including the Company’s stock price, the Company performed an interim goodwill impairment assessment. As a result, the Company recorded a partial goodwill impairment charge of $1.47 billion during the year ended December 31, 2020. The goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount, and an impairment charge is recognized 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. The Company applied the market approach using an average share price of the Company’s stock and a control premium to determine the fair value of the reporting unit.

We identified the assessment of the valuation of goodwill as a critical audit matter. The estimated fair value of the Company involved significant measurement uncertainty and required a high degree of subjective auditor judgment. We performed risk assessment procedures over assumptions used to estimate the fair value of the Company’s reporting unit and determined the length of time to determine the average stock price and the control premium represented the significant assumptions. The length of time used to determine the average stock price and the control premium assumptions used to estimate the fair value of the Company were challenging to test as they represented subjective determinations of market and economic conditions that were also sensitive to variation and minor changes to those assumptions could have had a significant effect on the Company’s assessment of the valuation of goodwill. Additionally, the audit effort associated with this assessment required specialized skills and knowledge.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the determination of the estimated fair value of the Company used in the valuation of goodwill, including controls over the (1) determination of the length of time used in the average stock price and (2) selection of the control premium used to develop the estimate. We evaluated the Company’s length of time used in the average stock price, by comparing the time frame selected to determine the average stock price to historical and economic information and market data. In addition, we involved valuation professionals with specialized skills and knowledge, who assisted in evaluating the control premium used by the Company in the valuation by comparing it against a control premium range that was independently developed using publicly available market data for comparable entities.

NOTE 1.  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 70 full-service branches located in California, one branch located in Durham, North Carolina, one branch located in Denver, Colorado, and numerous loan production offices across the country. The Bank provides community banking products including lending and comprehensive deposit and treasury management services to small and medium-sized businesses conducted primarily through our California-based branch offices and Denver, Colorado branch office. The Bank offers national lending products including asset-based, equipment, and real estate loans and treasury management services to established middle-market businesses on a national basis. The Bank also offers venture banking products including a comprehensive suite of financial services focused on entrepreneurial and venture-backed businesses and their venture capital and private equity investors, with offices located in key innovative hubs across the United States. In addition, we provide investment advisory and asset management services to select clients through Pacific Western Asset Management Inc., a wholly-owned subsidiary of the Bank and an 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 2020

Effective January 1, 2020, the Company adopted ASU 2016-13 and the related amendments to ASC Topic 326, “Financial Instruments - Credit Losses,” to replace the incurred loss accounting approach with a current expected credit loss approach for financial instruments measured at amortized cost and other commitments to extend credit. The new standard is generally intended to require earlier recognition of credit losses. While the standard changes the measurement of the allowance for credit losses, it does not change the credit risk of our lending portfolios or the ultimate losses in those portfolios.

Under the CECL approach, the standard requires immediate recognition of estimated credit losses expected to occur over the estimated remaining life of the asset. The forward-looking concept of CECL requires loss estimates to consider historical experience, current conditions and reasonable and supportable forecasts. The standard modifies the other-than-temporary impairment model for available-for-sale debt securities to require entities to record an allowance when recognizing credit losses for available-for-sale securities, rather than reducing the amortized cost of the securities by direct write-offs.

The Company adopted the new standard using the modified retrospective approach and recognized a cumulative effect adjustment to decrease retained earnings by $5.3 million, net of taxes, and increase the allowance for credit losses by $7.3 million without restating prior periods and applied the requirements of the new standard prospectively. There was no cumulative effect adjustment related to available-for-sale securities at adoption. The Company elected to account for accrued interest receivable separately from the amortized cost of loans and leases and investment securities. Accrued interest receivable is included in "Other assets" on the consolidated balance sheets. The Company elected the practical expedient to use the fair value of the collateral at the reporting date when determining the allowance for credit losses for a financial asset for which the repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty based on the entity’s assessment as of the reporting date (collateral dependent financial asset). Additionally, the Company implemented new business processes, new internal controls, and modified existing and/or implemented new internal models and tools to facilitate the ongoing application of the new standard. See Note 4. Loans and Leases for further details.

Notes to Consolidated Financial Statements

Effective January 1, 2020, the Company adopted ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" which simplifies 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. The goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount, and an impairment charge would be recognized 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.

The Company used this approach to evaluate its goodwill during the first quarter of 2020, as an unprecedented decline in economic conditions triggered by the Coronavirus Disease ("COVID-19") pandemic caused a significant decline in stock market valuations in March 2020, including our stock price. These events indicated that goodwill may be impaired and resulted in us performing a goodwill impairment assessment. We applied the market approach using an average share price of the Company's stock and a control premium to determine the fair value of the reporting unit. As a result, a goodwill impairment charge of $1.47 billion was recorded in the first quarter of 2020 as the Company's estimated fair value was less than its book value.

Effective January 1, 2020, the Company adopted the provisions of ASU 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework - Changes to Disclosure Requirements for Fair Value Measurements" which add disclosures regarding changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty. Although the guidance modifies our disclosures in 2020, there was no impact to our consolidated financial statements from the adoption of this new standard.

ASU 2020-03, "Codification Improvements to Financial Instruments" ("ASU 2020-03"), revised a wide variety of topics in the Codification with the intent to make the Codification easier to understand and apply by eliminating inconsistencies and providing clarifications. ASU 2020-03 was effective immediately upon its release in March 2020 and did not have a material impact to our consolidated financial statements.

(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

The Company has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period to prepare these consolidated financial statements in conformity with U.S. GAAP. Actual results could differ from those estimates. Material estimates subject to change in the near term include, among other items, the allowance for credit losses (the combination of the allowance for loan and lease losses and the reserve for unfunded loan commitments), the carrying value of goodwill and other intangible assets, and the realization of deferred tax assets. These estimates may be adjusted as more current information becomes available, and any adjustment may be significant.

(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 venture capital subclasses to better reflect and report our lending. Prior to the realignment, our venture capital subclasses were: (1) equity fund loans, (2) early stage, (3) expansion stage, and (4) late stage. After the realignment, our venture capital subclasses are: (1) equity fund loans and (2) venture lending (which includes early stage, expansion stage, and late stage). All of the loan and allowance tables, both current period and prior periods, reflect this realignment.

Notes to Consolidated Financial Statements

(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, (2) interest‑earning deposits in financial institutions, and (3) securities purchased under resale agreements. Interest‑earning deposits in financial institutions represent mostly cash held at the FRBSF, the majority of which is immediately available.

(f) Investment in Debt 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 and 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 value, with unrealized gains or losses reported as a separate component of stockholders’ equity in accumulated other comprehensive income (loss), 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. Such gains or losses are included in "Gain on sale of securities" on the consolidated statements of earnings (loss).

Prior to January 1, 2020, debt securities available-for-sale were measured at fair value and declines in the fair value were reviewed to determine whether the impairment was other-than-temporary. If the decline in fair value was considered temporary, the decline in fair value below the amortized cost basis of a security was recognized in other comprehensive income (loss). If we did not expect to recover the entire amortized cost basis of the security, then an other-than-temporary impairment was considered to have occurred. The cost basis of the security was written down to its estimated fair value and the amount of the write-down was recognized through a charge to earnings. If the amount of the amortized cost basis expected to be recovered increased in a future period, the cost basis of the security was not increased but rather recognized prospectively through interest income.

Effective January 1, 2020, upon the adoption of ASU 2016-13, debt securities available-for-sale are measured at fair value and are subject to impairment testing. A security is impaired if the fair value of the security is less than its amortized cost basis. When an available-for-sale debt security is considered impaired, the Company must determine if the decline in fair value has resulted from a credit-related loss or other factors and then, (1) recognize an allowance for credit losses by a charge to earnings for the credit-related component (if any) of the decline in fair value, and (2) recognize in other comprehensive income (loss) any non-credit related components (if any) of the fair value decline. If the amount of the amortized cost basis expected to be recovered increases in a future period, the valuation allowance would be reduced, but not more than the amount of the current existing allowance for that security.

(g) Equity and Other Investments

Investments in equity securities are classified into one of the following two categories and accounted as follows:

•Securities with a readily determinable fair value are reported at fair value, with changes in fair value recorded in earnings.

•Securities without a readily determinable fair value for which we have elected the "measurement alternative" are reported at cost less impairment (if any) plus or minus adjustments resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer.

113

PACWEST BANCORP AND SUBSIDIARIES

Notes to Consolidated Financial Statements

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. 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.”

Included in our equity investments that do not have a readily determinable fair value are our investments in non-public Small Business Investment Companies ("SBICs"). All of our SBIC investments meet the definition of investment companies, as defined in ASC 946, Financial Services - Investment Companies. We elected the practical expedient available in Topic 820, Fair Value Measurements, which permits the use of net asset value ("NAV") per share or equivalent to value investments in entities that are or are similar to investment companies. SBICs are required to value and report their investments at estimated fair value. We record the unrealized gains and losses resulting from changes in the fair value of our SBIC investments as gains or losses on equity investments in our consolidated statements of earnings (loss). The carrying value of our SBIC investments is equal to the capital account balance per each SBIC entities' quarterly financial statements.

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."

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 (loss).

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.

(h) 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 primarily 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 to determine if they have experienced a more-than-insignificant deterioration in credit quality since origination or issuance as of the acquisition date and are accounted for as “acquired non‑PCD” or “purchased credit deteriorated” loans.

Acquired non‑PCD loans. Acquired non‑PCD loans are those loans for which there was no evidence of a more-than-insignificant credit deterioration at their acquisition date and it was probable that we would be able to collect all contractually required payments. Acquired non‑PCD loans, together with originated loans, are referred to as Non‑PCD loans. Purchase discounts or premiums on acquired non‑PCD 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.

114

PACWEST BANCORP AND SUBSIDIARIES

Notes to Consolidated Financial Statements

Purchased loans with credit deterioration. Prior to January 1, 2020, purchased credit impaired loans were accounted for in accordance with ASC Subtopic 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality.” At the time of acquisition, these loans were recorded at estimated fair value based upon estimated future cash flows with no related allowance for credit losses.

Effective January 1, 2020, upon the adoption of ASU 2016-13, an entity records purchased financial assets with credit deterioration ("PCD assets") at the purchase price plus the allowance for credit losses expected at the time of acquisition. This allowance is recognized through a gross-up that increases the amortized cost basis of the asset with no effect on net income. Subsequent changes (favorable and unfavorable) in expected cash flows are recognized immediately in net income by adjusting the related allowance.

Leases to customers. We provide equipment financing to our customers primarily with direct financing and operating leases. 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 accounting for allowance for loans and leases.

We provide equipment financing through operating leases where we facilitate the purchase of equipment leased to customers. The equipment is shown on our consolidated balance sheets as "Equipment leased to others under operating leases" and is depreciated to its estimated residual value at the end of the lease term, shown as "Leased equipment depreciation" in the consolidated statements of earnings (loss), according to our fixed asset accounting policy. We receive periodic rental income payments under the leases, which are recorded as "Noninterest income" in the consolidated statements of earnings (loss).

Delinquent or past due loans and leases. Loans and leases are considered delinquent when principal or interest payments are past due 30 days or more. Delinquent loans may remain on accrual status between 30 days and 89 days past due.

Nonaccrual loans and leases. When we discontinue the accrual of interest on a loan or lease it is designated as nonaccrual. We discontinue the accrual of interest on a loan 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.

Individually Evaluated Loans and Leases. Loans and leases that do not share similar risk characteristics with other financial assets are individually evaluated for impairment and excluded from loan pools used within the collective evaluation of estimated credit losses. We defined the following criteria for what constitutes a “default”, which results in a loan no longer sharing similar risk characteristics with other loans, and therefore requires an individual evaluation for expected credit losses. The criteria for default may include any one of the following:

•On nonaccrual status,

•Modified under a TDR,

•Payment delinquency of 90 days or more,

•Partial charge-off recognized,

•Risk rated doubtful or loss, or

•Reasonably expected to be modified under a TDR.

115

PACWEST BANCORP AND SUBSIDIARIES

Notes to Consolidated Financial Statements

Defaulted loans and leases with outstanding balances over $250,000 are reviewed individually for expected credit loss. Individually evaluated loans are measured at the present value of the expected future cash flows discounted at the loan's initial effective interest rate, unless the loans are collateral dependent, in which case loan impairment is based on the estimated fair value of the underlying collateral. A loan is considered collateral-dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the 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. An individually evaluated reserve and/or charge off would be recognized when the present value of expected future cash flows or the fair value of the underlying collateral is below the amortized cost of the loan. If the measured amount of any individually reviewed loan exceeds its amortized cost, further review is required to determine whether a positive allowance should be added (but only up to amounts previously written off) to its amortized cost basis in order to reflect the net amount expected to be collected.

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.

The Company has granted various commercial and consumer loan modifications to provide borrowers relief from the economic impacts of COVID-19. In accordance with the Coronavirus Aid, Relief, and Economic Security ("CARES") Act, the Company elected to not apply TDR classification to COVID-19 related loan modifications that met all of the requisite criteria as stipulated in the CARES Act.

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. Loan modifications that qualify as troubled debt restructurings are individually evaluated for expected credit losses 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.

Impaired loans and leases. Prior to January 1, 2020, a loan or lease was considered impaired when it was probable that we would be unable to collect all amounts due according to the contractual terms of the loan or lease agreement. Impaired loans and leases included loans and leases on nonaccrual status and performing troubled debt restructured loans. Income from impaired loans was recognized on an accrual basis unless the loan was on nonaccrual status. Income from loans on nonaccrual status was recognized to the extent cash was received and when the loan’s principal balance was deemed collectable. We measured 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 was 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 was not collateral‑dependent. The impairment amount on a collateral‑dependent loan or lease was charged‑off, and the impairment amount on a loan that was not collateral‑dependent was generally recorded as a specific reserve within our allowance for loan and lease losses.

(i) Allowance for Credit Losses on Loans and Leases Held for Investment

Effective January 1, 2020, upon the adoption of ASU 2016-13, the Company replaced the incurred loss accounting approach with the current expected credit loss ("CECL") approach for financial instruments measured at amortized cost and other commitments to extend credit. CECL requires the immediate recognition of estimated credit losses expected to occur over the estimated remaining life of the asset. The forward-looking concept of CECL requires loss estimates to consider historical experience, current conditions and reasonable and supportable forecasts.

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 the amortized cost basis of loans and leases, while the reserve for unfunded loan commitments is included within "Accrued interest payable and other liabilities" on the consolidated balance sheets. The amortized cost basis of loans and leases does not include accrued interest receivable, which is included in "Other assets" on the consolidated balance sheets. The "Provision for credit losses" on the consolidated statements of earnings (loss) is a combination of the provision for loan and lease losses and the provision for unfunded loan commitments.

Under the CECL methodology, expected credit losses reflect losses over the remaining contractual life of an asset, considering the effect of prepayments and available information about the collectability of cash flows, including information about relevant historical experience, current conditions, and reasonable and supportable forecasts of future events and circumstances. Thus, the CECL methodology incorporates a broad range of information in developing credit loss estimates. The resulting allowance for loan and lease losses is deducted from the associated amortized cost basis to reflect the net amount expected to be collected. Subsequent changes in this estimate are recorded through the provision for credit losses and the allowance. The CECL methodology could result in significant changes to both the timing and amounts of provision for credit losses and the allowance as compared to historical periods. Loans and leases that are deemed to be uncollectable are charged off and deducted from the allowance. The provision for credit losses and recoveries on loans and leases previously charged off are added to the allowance.

The allowance for loan and lease losses is comprised of an individually evaluated component for loans and leases that no longer share similar risk characteristics with other loans and leases and a pooled loans component for loans and leases that share similar risk characteristics.

A loan or lease with an outstanding balance greater than $250,000 is individually evaluated for expected credit loss when it is probable that we will be unable to collect all amounts due according to the original contractual terms of the agreement. We select loans and leases for individual assessment on an ongoing basis using certain criteria such as payment performance, borrower reported and forecasted financial results, and other external factors when appropriate. We measure the current expected credit loss of an individually evaluated 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 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.

Our CECL methodology for the pooled loans component includes both quantitative and qualitative loss factors which are applied to our population of loans and leases and assessed at a pool level. The quantitative CECL model estimates credit losses by applying pool-specific probability of default ("PD") and loss given default ("LGD") rates to the expected exposure at default ("EAD") over the contractual life of loans and leases. The qualitative component considers internal and external risk factors that may not be adequately assessed in the quantitative model.

The loan portfolio is segmented into four loan segments, eight loan classes, and 19 loan pools (excluding Paycheck Protection Program loans, which are fully government guaranteed) based upon loan type that share similar default risk characteristics to calculate quantitative loss factors for each pool. Three of these loan pools have insignificant current balances and/or insignificant historical losses, thus, estimated losses are calculated using historical loss rates from the first quarter of 2009 to the current period rather than econometric regression modeling. For the remaining 16 loan pools, we estimate the PD during the reasonable and supportable forecast period using seven econometric regression models developed to correlate macroeconomic variables to historical credit performance (based on quarterly transition matrices from 2009 to 2019, which include risk rating upgrades/downgrades and defaults).

Notes to Consolidated Financial Statements

The loans and unfunded commitments are grouped into nine LGD pools based on portfolio classes that share similar collateral risk characteristics. LGD rates are computed based on the net charge-offs recognized divided by the EAD of defaulted loans starting with the first quarter of 2009 to the current period. The PD and LGD rates are applied to the EAD at the loan or lease level based on contractual scheduled payments and estimated prepayments. We use our actual historical loan prepayment experience from 2009 to 2019 to estimate future prepayments by loan pool. Loans and leases with outstanding balances less than or equal to $250,000, where it is probable that we will be unable to collect all amounts due according to the contractual terms of the agreement, remain in their respective pools and are assigned a 100% probability of default.

For the reasonable and supportable forecast period, future macroeconomic events and circumstances are estimated over a 4-quarter time horizon using a single scenario economic forecast that is consistent with management's current expectations for the 16 loan pools. We use economic forecasts from Moody's Analytics in this process. The economic forecast is updated monthly; therefore, the one used for each quarter-end calculation is generally released a few weeks prior to quarter-end. If economic conditions as of the balance sheet date change materially, management would consider a qualitative adjustment. The key macroeconomic assumptions used in each of the seven PD regression models include two or three of the following economic indicators: Real GDP, unemployment rates, CRE Price Index, the BBB corporate spread, nominal disposable income, and CPI.

The quantitative CECL model applies the projected rates based on the economic forecasts for the 4-quarter reasonable and supportable forecast horizon to EAD to estimate defaulted loans. During this forecast horizon, prepayment rates during a historical period that exhibits economic conditions most similar to the economic forecast are used to estimate EAD. If no historical period from 2009 to 2019 exhibits economic conditions that are similar to the economic forecast, management uses its best estimate of prepayments expected over the reasonable and supportable forecast period which may, in some circumstances, be the average of all historical prepayment experience. Historical LGD rates are applied to estimated defaulted loans to determine estimated credit losses. We then use a 2-quarter reversion period to revert on a straight-line basis from the PD, LGD, and prepayment rates used during the reasonable and supportable forecast period to the Company’s historical PD, LGD, and prepayment experience. Subsequent to the reversion period for the remaining contractual life of loans and leases, the PD, LGD, and prepayment rates are based on historical experience from 2009 to 2019. PD regression models and prepayment rates are updated on an annual basis. LGD rates are updated every quarter to reflect current charge-off activity.

The PDs calculated by the quantitative models are highly correlated to our internal risk ratings assigned to each loan and lease. 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 and leases on a regular basis. The credit risk ratings assigned to every loan and lease are as follows:

•High Pass: (Risk ratings 1-2) Loans and leases rated as "high pass" exhibit a favorable credit profile and have minimal risk characteristics. Repayment in full is expected, even in adverse economic conditions.

•Pass: (Risk ratings 3-4) Loans and leases rated as "pass" are not adversely classified and collection and repayment in full are expected.

•Special Mention: (Risk rating 5) 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.

•Substandard: (Risk rating 6) 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.

•Doubtful: (Risk rating 7) 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.

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 4. Loans and Leases.

Notes to Consolidated Financial Statements

In addition to our internal risk rating process, our federal and state banking regulators, as an integral part of their examination process, periodically review the Company’s loan and lease risk rating classifications. Our regulators may require the Company to recognize rating downgrades based on 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.

The qualitative portion of the reserve on pooled loans and leases represents management’s judgment of additional considerations to account for internal and external risk factors that are not adequately measured in the quantitative reserve. The qualitative loss factors consider idiosyncratic risk factors, conditions that may not be reflected in quantitatively derived results, or other relevant factors to ensure the allowance for credit losses reflects our best estimate of current expected credit losses. Current and forecasted economic trends and underlying market values for collateral dependent loans are generally considered to be encompassed within the CECL quantitative reserve. An incremental qualitative adjustment may be considered when economic forecasts exhibit higher levels of volatility or uncertainty.

In addition to economic conditions and collateral dependency, the other qualitative criteria we consider when establishing the loss factors include the following:

•Legal and Regulatory - matters that could impact our borrowers’ ability to repay our loans and leases;

•Concentrations - loan and lease portfolio composition and any loan concentrations;

•Lending Policy - current lending policies and the effects of any new policies or policy amendments;

•Nature and Volume - loan and lease production volume and mix;

•Problem Loan Trends - loan and lease portfolio credit performance trends, including a borrower's financial condition, credit rating, and ability to meet loan payment requirements;

•Loan Review - results of independent credit review; and

•Management - changes in management related to credit administration functions.

We estimate the reserve for unfunded loan commitments using the same PD, LGD, and prepayment rates for the quantitative credit losses and qualitative loss factors as used for the allowance for loan and lease losses. The EAD for the reserve for unfunded loan commitments is computed using expected future utilization rates of the unfunded commitments during the contractual life of the commitments based on historical usage by loan pool from 2015 to 2019. The utilization rates are updated on an annual basis.

The CECL methodology requires a significant amount of management judgment in determining the appropriate allowance for credit losses. Most of the steps in the methodology involve judgment and are subjective in nature including, among other things: segmenting the loan and lease portfolio; determining the amount of loss history to consider; selecting predictive econometric regression models that use appropriate macroeconomic variables; determining the methodology to forecast prepayments; selecting the most appropriate economic forecast scenario; determining the length of the reasonable and supportable forecast and reversion periods; estimating expected utilization rates on unfunded loan commitments; and assessing relevant and appropriate qualitative factors. In addition, the CECL methodology is dependent on economic forecasts which are inherently imprecise and will change from period to period. Although the allowance for credit losses is considered appropriate, there can be no assurance that it will be sufficient to absorb future losses.

Management believes the allowance for credit losses is appropriate for the current expected credit losses in our loan and lease portfolio and associated unfunded commitments, and the credit risk ratings and inherent loss rates currently assigned are reasonable and appropriate as of the reporting date. 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 consolidated financial statements.

Notes to Consolidated Financial Statements

Prior to January 1, 2020, the allowance for loan losses was measured using the incurred loss accounting approach. The allowance for credit losses was 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 was 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.

The allowance for loan and lease losses had a general reserve component for unimpaired loans and leases and a specific reserve component for impaired loans and leases.

A loan or lease was considered impaired when it was probable that we would be unable to collect all amounts due according to the original contractual terms of the agreement. We assessed 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 measured impairment of a loan or lease based upon the fair value of the underlying collateral if the loan or lease was collateral-dependent or the present value of cash flows, discounted at the effective interest rate, if the loan or lease was not collateral-dependent. To the extent a loan or lease balance exceeded the estimated collectable value, a specific reserve or charge-off was recorded depending upon either the certainty of the estimate of loss or the fair value of the loan’s collateral if the loan was collateral-dependent. Impaired loans and leases with outstanding balances less than or equal to $250,000 might not be individually assessed for impairment but would be 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 included both quantitative and qualitative loss factors which were applied to our population of unimpaired loans and leases to estimate our general reserves. The quantitative loss factors determination was based on a probability of default/loss given default ("PD/LGD") methodology which considered 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 had higher quantitative loss factors. The qualitative loss factors considered, among other things, current economic trends and forecasts, current collateral values and performance trends, credit performance trends, and the loan portfolio's current composition.

The quantitative estimation of the allowance for credit losses considered actual historical loan and lease charge-off experience over a 44-quarter look-back period starting with the first quarter of 2009. This look-back period was inclusive of the average timeframe over which charge-offs typically occurred following loan or lease origination and allowed for the capture of sufficient loss observations that were relevant to the current portfolio. When estimating the general reserve component for the various pools of similar loan types, the loss factors applied to the loan pools considered the current credit risk ratings, giving greater weight to loans with more adverse credit risk ratings. We recognized that the determination of the allowance for credit losses was sensitive to the assigned credit risk ratings and inherent loss rates at any given point in time.

(j) Land, Premises and Equipment

Premises and equipment are stated at cost less accumulated depreciation and amortization. Land is not depreciated. Depreciation and amortization is charged to "Noninterest expense" in the consolidated statements of earnings (loss) 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.

Notes to Consolidated Financial Statements

(k) 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 (loss) 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."

(l) Income Taxes

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

On a periodic 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.

(m) 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 annually unless a triggering event occurs thereby requiring an updated assessment. Our regular annual impairment assessment occurs in the fourth quarter. Goodwill represents the excess of the purchase price over the fair value of the net assets and other identifiable intangible assets acquired. Impairment exists when the carrying value of the goodwill exceeds its 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 (loss).

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 amount would be recognized as a charge to "Noninterest expense" in the consolidated statements of earnings (loss).

(n) Operating Leases

As of December 31, 2020, the Company only had operating leases related to our leased facilities. The Company determines if an arrangement is a lease at inception by assessing whether there is an identified asset and whether the contract conveys the right to control the use of the identified asset for a period of time in exchange for consideration. Operating leases with a term of more than one year are included in operating lease ROU assets and operating lease liabilities, which are reported in "Other assets" and "Accrued interest payable and other liabilities" on the Company's consolidated balance sheets. The Company made a policy election to apply the short-term lease exemption to any operating leases with an original term of less than 12 months, therefore no ROU asset or lease liability is recorded for these operating leases. The Company has agreements with lease and non-lease components, which are accounted for as a single lease component.

ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized on the lease commencement date based on the present value of lease payments over the lease term. The Company uses the incremental borrowing rate commensurate with the lease term based on the information available at the lease commencement date in determining the present value of lease payments. ROU assets initially equal the lease liability, adjusted for any prepaid lease payments and initial direct costs incurred less any lease incentives received.

Certain of the Company's lease agreements include rental payments that adjust periodically based on changes in the CPI. We initially measure the present value of the lease payments using the index at the lease commencement date. Subsequent increases in the CPI are treated as variable lease payments and recognized in the period in which the obligation for those payments is incurred. The ROU assets and lease liabilities are not re-measured as a result of changes in the CPI. The Company's lease terms may include options to extend or terminate the lease. These options to extend or terminate are assessed on a lease-by-lease basis, and the ROU assets and lease liabilities are adjusted when it is reasonably certain that an option will be exercised. Rent expense for lease payments is recognized on a straight-line basis over the lease term and is included in "Occupancy expense" on the Company's consolidated statements of earnings (loss).

The Company uses the long-lived assets impairment guidance under ASC Topic 360-10-35, "Property, Plant and Equipment," to determine whether an ROU asset is impaired, and if impaired, the amount of loss to recognize. Long-lived assets are tested for recoverability whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. These could include vacating the leased space, obsolescence, or physical damage to a facility. Under ASC Topic 842, "Leases," if an impairment loss is recognized for a ROU asset, the adjusted carrying amount of the ROU asset would be its new accounting basis. The remaining ROU asset (after the impairment write-down) is amortized on a straight-line basis over the remaining lease term.

(o) 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 and the employee continues to meet the service requirement of the award.

122

PACWEST BANCORP AND SUBSIDIARIES

Notes to Consolidated Financial Statements

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 only paid 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.

(p) Derivative Instruments

The Company uses derivatives to manage exposure to market risk, primarily foreign currency risk and interest rate risk, and to assist customers with their risk management objectives. The Company uses foreign exchange contracts to manage the foreign exchange rate risk associated with certain foreign currency-denominated assets and liabilities. As of December 31, 2020, 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 foreign currency derivatives are carried at fair value and 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 (loss).

The Bank offers interest rate swap products to certain loan customers to allow them to hedge the risk of rising interest rates on their variable rate loans. When such products are issued, we also enter into an offsetting swap with institutional counterparties to eliminate the interest rate risk to us. These back-to-back swap agreements, which generate fee income for us, are intended to offset each other. We retain the credit risk of the original loan. The net cash flow for us is equal to the interest income received from a variable rate loan originated with the client plus a fee. These swaps are not designated as accounting hedges and are recorded at fair value in "Other assets" and "Accrued interest payable and other liabilities" in the consolidated balance sheets. The changes in fair value are recorded in "Noninterest income - other" in the consolidated statements of earnings (loss).

In connection with negotiated credit facilities and certain other services, we may obtain equity warrant assets giving us the right to acquire stock in primarily private, venture-backed companies. We account for equity warrant assets as derivatives when they contain net settlement terms and other qualifying criteria under ASC 815. These equity warrant assets are measured at estimated fair value on a monthly basis and are classified as "Other assets" in the consolidated balance sheets at the time they are obtained.

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.

(q) Comprehensive Income (Loss)

Comprehensive income (loss) 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 (loss).

(r) Earnings (Loss) 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 (loss) 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 (loss) to determine that amount of earnings (loss) available to common stockholders. In the two‑class method, the amount of our earnings (loss) available to common stockholders is divided by the weighted average shares outstanding, excluding any unvested restricted stock, for both the basic and diluted earnings (loss) per share.

(s) 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 consolidated statements of earnings (loss) from the date of acquisition. Acquisition‑related costs, including conversion and restructuring charges, are expensed as incurred.

(t) 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, 2020 and since December 31, 2015, we operated as one reportable segment. The factors considered in making this determination include the nature of products and offered services, geographic regions in which we operate, the applicable regulatory environment, and the discrete financial information reviewed by our key decision makers. Through our network of banking offices nationwide, our entire operations provide relationship-based banking products, services and solutions for small to mid-sized companies, entrepreneurial and venture-backed 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.

The securities that were in an unrealized loss position at December 31, 2020, were considered impaired and required further review to determine if the unrealized losses were credit-related. We 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. We also considered the seniority of the tranches and U.S. government agency guarantees, if any, to assess whether an unrealized loss was credit-related. Accordingly, we determined the unrealized losses were not credit-related and recognized the unrealized losses in "other comprehensive income" in stockholders' equity. Although we periodically sell securities for portfolio management purposes, we do not foresee having to sell any impaired securities strictly for liquidity needs and believe that it is more likely than not we would not be required to sell any impaired securities before recovery of their amortized cost.

Contractual Maturities of Securities Available-for-Sale

The following table presents the contractual maturities of our available-for-sale securities portfolio based on amortized cost and carrying value as of the date indicated.

	December 31, 2020
	Amortized		Fair
Maturity	Cost		Value
	(In thousands)
Due in one year or less	$	6,063	$	6,091
Due after one year through five years	575,561		606,388
Due after five years through ten years	1,306,179		1,368,746
Due after ten years	3,109,167		3,254,366
Total securities available-for-sale	$	4,996,970	$	5,235,591

MBS and CMOs have contractual maturity dates, but require periodic payments based upon scheduled amortization terms. Actual principal collections on these securities usually occur more rapidly than the scheduled amortization terms because of prepayments made by obligors of the underlying loan collateral.

FHLB Stock

In connection with outstanding FHLB advances, the Bank owned FHLB stock carried at cost of $17.3 million and $40.9 million at December 31, 2020 and 2019. At December 31, 2020 and 2019, the Bank was required to own FHLB stock equal to a percentage of outstanding FHLB advances. During the year ended December 31, 2020, FHLB stock decreased by $23.7 million due mainly to $68.5 million in redemptions, offset partially by $44.8 million in purchases. We evaluated the carrying value of our FHLB stock investment at December 31, 2020 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.

TDRs are a result of rate reductions, term extensions, fee concessions, transfers to foreclosed assets, discounted loan payoffs, and debt forgiveness, or a combination thereof. The Company has granted various commercial and consumer loan modifications to provide borrowers relief from the economic impacts of COVID-19. In accordance with the CARES Act, the Company elected to not apply TDR classification to COVID-19 related loan modifications that met all of the requisite criteria as stipulated in the CARES Act.

Leases Receivable

We provide equipment financing to our customers primarily with operating and direct financing leases. For direct financing leases, lease receivables are recorded on the balance sheet but the leased equipment is not, although we generally retain legal title to the leased equipment 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. Direct financing leases are subject to our accounting for allowance for loan and lease losses. See Note 9. Leases for information regarding operating leases where we are the lessor.

The following table provides the components of leases receivable income for the period indicated:

The allowance for loan and lease losses increased by $209.4 million in 2020 due primarily to a provision for loan and lease losses of $293.0 million. The higher provision for loan and lease losses in 2020 was primarily a result of the impact of the current economic forecast used in our ACL estimation, which reflected a significant deterioration in key macro-economic forecast variables such as unemployment and Real GDP as a result of the COVID-19 pandemic, significant loan downgrades into special mention, and higher provisions on individually evaluated loans.

We actively participated in the Paycheck Protection Program ("PPP"), under the provisions of the CARES Act during the second quarter of 2020. As of December 31, 2020, PPP loans had an outstanding balance of approximately $1.1 billion. The loans have two or three year terms, are fully guaranteed by the SBA, and do not carry an allowance.

A loan is considered collateral-dependent, and is individually evaluated for reserve purposes, when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral.

NOTE 7.  GOODWILL AND OTHER INTANGIBLE ASSETS, NET

The unprecedented decline in economic conditions triggered by the COVID-19 pandemic caused a significant decline in stock market valuations in March 2020, including our stock price. These triggering events indicated that goodwill related to our single reporting unit may be impaired and resulted in us performing a goodwill impairment assessment in the first quarter of 2020. We applied the market approach using an average share price of the Company's stock and a control premium to determine the fair value of the reporting unit. The control premium was based upon management judgment using historical information of control premiums for completed bank acquisitions. As a result, we recorded a goodwill impairment charge of $1.47 billion in the first quarter of 2020 as the estimated fair value of equity was less than book value. This was a non-cash charge to earnings and had no impact on our regulatory capital ratios, cash flows, or liquidity position.

In performing our annual goodwill assessment in the fourth quarter of 2020, we considered relevant events and circumstances that may affect the fair value or carrying amount of our reporting unit. The events and circumstances we considered included macroeconomic conditions, industry conditions, and our financial performance. Based on our qualitative assessment, we concluded that there were no conditions, changes in operations, or results that indicated a triggering event had occurred in the fourth quarter of 2020. Thus, a quantitative assessment was not required and we determined that it was more likely than not that the fair value of the reporting unit was greater than its carrying value and there was no evidence of impairment.

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

	Goodwill
	(In thousands)
Balance, December 31, 2019	$	2,548,670
Impairment	(1,470,000)
Balance, December 31, 2020	$	1,078,670

Our other intangible assets with definite lives are CDI and CRI. CDI and CRI are amortized over their respective estimated useful lives and reviewed for impairment at least quarterly. The amortization expense represents the estimated decline in the value of the underlying deposits or customer relationships acquired.

____________________

(1)    During the first quarter of 2020, the Company increased the amount of its investment in low income housing project partnerships by $101 million representing the amount of related unfunded commitments, with an offset to a liability included in "Accrued interest payable and other liabilities" on the consolidated balance sheets.

(2)    See Note 9. Leases for further details regarding the operating lease ROU assets.

(3)    During the third quarter of 2020, the Company prospectively changed the accounting method for its SBIC investments from modified cost to NAV fair value.

(4)    For information regarding equity warrants, see Note 12. Derivatives.

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 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 in excess of the cash surrender value are recorded to "Noninterest income - other."

The Company's equity investments without readily determinable fair values include investments in privately held companies, limited partnerships, entities from which we issued trust preferred securities, CRA-related loan pool investments, and CRA-related equity investments. The CRA-related loan pool and 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. We measure our equity investments without readily determinable fair values using the measurement alternative. Carrying values of these investments are adjusted to fair value upon observable transactions for identical or similar investments of the same issuer. Unrealized and realized gains and losses on equity investments without readily determinable fair values are recorded in "Noninterest income - other" on the consolidated statements of earnings (loss).

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. Unrealized and realized gains and losses on equity investments with readily determinable fair values are recorded in "Noninterest income - other" on the consolidated statements of earnings (loss).

NOTE 9. LEASES

We determine if an arrangement is a lease at inception by assessing whether there is an identified asset, and whether the contract conveys the right to control the use of the identified asset for a period of time in exchange for consideration. ASC Topic 842 also requires a lessee to classify a lease as either finance or operating.

ROU assets represent a lessee's right to use an underlying asset for the lease term and lease liabilities represent a lessee's obligation to make lease payments arising from the lease. We amortize the operating lease ROU assets and record interest expense on the operating lease liabilities over the lease terms.

Operating leases with a term of more than one year are included in operating lease ROU assets and operating lease liabilities, which are reported in "Other assets" and "Accrued interest payable and other liabilities" on the Company's consolidated balance sheets. Short-term leases (initial term of less than 12 months) are not recorded on the balance sheet and lease expense is recognized on a straight-line basis over the lease term. We have lease agreements with lease and non-lease components, which are accounted for as a single lease component. Most leases include one or more options to renew, with renewal terms that can extend the lease from one to ten years. The exercise of lease renewal options is at our sole discretion. Some of our leases also include termination options. We have determined that we do not meet the reasonably certain threshold to exercise any renewal or termination options, therefore our lease terms do not reflect any optional periods. We rent or sublease certain office space to third parties. Our subleases consist of operating leases for offices that we have fully or partially vacated.

Certain of our lease agreements also include rental payments that adjust periodically based on changes in the CPI. We initially measured our lease payments using the index at the lease commencement date. Subsequent increases in the CPI are treated as variable lease payments and recognized in the period in which the obligation for those payments is incurred. The ROU assets and lease liabilities are not re-measured as a result of changes in the CPI. Our lease agreements do not contain any purchase options, residual value guarantees, or restrictive covenants.

Operating Leases as a Lessee

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

Interest payments made by the Company on subordinated debentures are considered dividend payments under FRB regulations. Bank holding companies, such as PacWest, are required to notify and receive approval from 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. 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. Since the impact of the goodwill impairment charge on net earnings in the first quarter of 2020, we are required to receive approval from the FRB prior to declaring a dividend until such time the applicable regulations no longer require such approval.

NOTE 12.  DERIVATIVES

The Company uses derivatives to manage exposure to market risk, primarily foreign currency risk and interest rate risk, and to assist customers with their risk management objectives. Our derivatives are carried at fair value and recorded in "Other assets" or "Accrued interest payable and other liabilities," as appropriate, in the consolidated balance sheets. The changes in fair value of our derivatives and the related fees are recognized in "Noninterest income - other" in the consolidated statements of earnings (loss). For the year ended December 31, 2020, changes in fair value and fees recorded to noninterest income in the consolidated statements of earnings (loss) were immaterial. See Note 8. Other Assets for additional information regarding equity warrant assets.

Notes to Consolidated Financial Statements

The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit 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 several of our lending arrangements and property lease obligations. Most guarantees expire within one year from the date of issuance. If a borrower defaults on its commitments subject to any letter of credit issued under these arrangements, we would be required to meet the borrower's financial obligation but would seek repayment of that financial obligation from the borrower. In some cases, borrowers have pledged cash and investment securities as collateral under these arrangements.

Additionally, we have commitments to invest in SBICs that call for capital contributions up to an amount specified in the partnership agreements, and in CRA-related loan pools. As of December 31, 2020, such commitments totaled $55.5 million. As of December 31, 2019, in addition to commitments for SBICs and CRA-related loan pools, we also had commitments to invest in low income housing projects that provide income tax credits. Total commitments to these entities totaled $129.2 million. We also had commitments to contribute up to an additional $50,000 to private equity funds at December 31, 2019.

The following table presents the years in which commitments are expected to be paid for our commitments to contribute capital to SBICs and CRA-related loan pools as of the date indicated:

	December 31, 2020
	(In thousands)
Year Ending December 31,
2021	$	27,750
2022	27,749
Total	$	55,499

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. The range of any reasonably possible liabilities is also not significant.

NOTE 14.  FAIR VALUE MEASUREMENTS

ASC Topic 820, “Fair Value Measurement,” defines fair value, establishes a framework for measuring fair value including a three‑level valuation hierarchy, and expands disclosures about fair value measurements. Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date reflecting assumptions that a market participant would use when pricing an asset or liability. The hierarchy uses three levels of inputs to measure the fair value of assets and liabilities as follows:

•Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets.

•Level 2: Observable inputs other than Level 1, including quoted prices for similar assets and liabilities in active markets, quoted prices in less active markets, or other observable inputs that can be corroborated by observable market data, either directly or indirectly, for substantially the full term of the financial instrument. This category generally includes agency residential CMOs, agency commercial and residential MBS, municipal securities, collateralized loan obligations, registered publicly rated private label CMOs, corporate debt securities, SBA securities, and asset-backed securitizations.

•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 individually evaluated loans and leases and other real estate owned and also to record impairment on certain assets, such as goodwill, CDI, and other long-lived assets.

The Company also holds SBIC investments measured at fair value using the NAV per share practical expedient that are not required to be classified in the fair value hierarchy. At December 31, 2020, the fair value of these investments was $32.3 million.

Notes to Consolidated Financial Statements

The following is a description of the valuation methodologies used to measure our assets recorded at fair value (under ASC Topic 820, “Fair Value Measurement”) and for estimating fair value for financial instruments not recorded at fair value (under ASC Topic 825).

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 3. 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.

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. Had significant changes in default expectations, loss severity factors, or discount rates occurred all together or in isolation, it would have resulted in different fair value measurements at December 31, 2020.

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 measured using the exit price and 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. The Community Bank group originates and purchases a number of similar, homogeneous loans. For this portfolio, management may make adjustments to the discount rate arrived at using the previously described methodology based upon the pricing for recent loan pool purchases and/or rates on recent originations.

Individually evaluated loans and leases. Defaulted loans and leases with outstanding balances over $250,000 are reviewed individually for expected credit loss, if any, and are recorded at fair value on a non-recurring basis. These defaulted loans and leases are excluded from the loan pools used within the collective evaluation of estimated credit losses.

To the extent a defaulted loan or lease is collateral dependent, we measure expected credit loss 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, 2020.

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 individually evaluated loans and leases 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 individually evaluated loan and lease balances shown above as measured on a non-recurring basis represent those defaulted loans and leases for which expected credit loss was recognized during the year ended December 31, 2020. The amounts shown as net losses include the expected credit loss recognized during the year ended December 31, 2020, for the loan and lease balances shown.

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, 2020.

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. We typically classify our equity warrant derivatives in Level 3 of the fair value hierarchy.

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.” 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.

Notes to Consolidated Financial Statements

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.

Limitations

Fair value estimates are made at a specific point in time and are based on relevant market information and information about the financial instrument. These estimates do not reflect income taxes or any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a portion of the Company’s financial instruments, fair value estimates are based on what management believes to be reasonable judgments regarding expected future cash flows, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimated fair values are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Since the fair values have been estimated as of December 31, 2020, 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 $23.5 million for 2020, $16.7 million for 2019, and $11.9 million for 2018.

At December 31, 2020, we had no federal net operating loss carryforwards and approximately $546.3 million 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 from 2021 through 2040. 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.

As of December 31, 2020, for federal tax purposes, we had foreign tax credit carryforwards of $2.2 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.

Notes to Consolidated Financial Statements

The Company had net income taxes receivable of $59.3 million and $30.8 million at December 31, 2020 and December 31, 2019.

As of December 31, 2020 and 2019, the Company had a valuation allowance of $41.1 million and $46.4 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, 2020 was $5.3 million. Of this amount, $4.2 million consisted principally of adjustments to state net operating loss DTAs. The adjustment to the state operating loss DTAs at December 31, 2020, was a result of changes in state apportionments. The DTAs had been subjected to a full valuation allowance because the Company had previously determined that they were more likely than not to be expired unused. As a result, the change in the tax attributes supporting the $4.2 million of deferred tax assets had no impact on the Company's effective tax rate for the year ended December 31, 2020. The remaining $1.1 million reduction in the valuation allowance was primarily due to an increase in the amount of foreign tax credit expected to be utilized prior to expiration and adjustments to capital deferred tax assets.

The following table summarizes the activity related to the Company's unrecognized tax benefits for the years indicated:

	Year Ended December 31,
Unrecognized Tax Benefits	2020		2019
	(In thousands)
Balance, beginning of year	$	10,748	$	9,572
Increase based on tax positions related to prior years	879		1,733
Reductions for tax positions related to prior years	(7,813)		—
Reductions related to settlements	—		(255)
Reductions for tax positions as a result of a lapse of the applicable statute of limitations	(438)		(302)
Balance, end of year	$	3,376	$	10,748
Unrecognized tax benefits that would affect the effective tax rate if recognized	$	3,376	$	6,981

Due to the potential for the resolution of federal and state examinations and the expiration of various statutes of limitations, it is reasonably possible that our gross unrecognized tax benefits may decrease within the next twelve months by as much as $0.1 million.

We recognize interest and penalties related to unrecognized tax benefits as a component of income tax expense. For the year ended December 31, 2020, we reduced our accrual for interest expense and penalties and recognized $0.2 million in tax benefit for these items. For the year ended December 31, 2019, we recognized $0.7 million in expense related to these items. For the year ended December 31, 2018, we recognized $0.2 million in expense for interest expense and penalties. We had $1.3 million and $1.5 million accrued for the payment of interest and penalties as of December 31, 2020 and 2019.

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 2016 through 2019. We are currently under examination by certain state jurisdictions for tax years 2012 through 2018.

NOTE 17. REVENUE FROM CONTRACTS WITH CUSTOMERS

Revenue from contracts with customers 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. Such 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, 2020.

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 ASC 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:

•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.

•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.

NOTE 18.  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, 2020, there were 1,734,014 shares available for grant under the 2017 Plan. Though frozen for new issuances, certain awards issued under the 2003 Stock Incentive Plan remain outstanding, and are due to vest no later than February 2021.

Restricted Stock

Restricted stock amortization totaled $23.7 million, $26.2 million, and $29.1 million for the years ended December 31, 2020, 2019, and 2018. Such amounts are included in compensation expense on the accompanying consolidated statements of earnings (loss) and exclude $627,000, $598,000, and $627,000 of stock-based compensation expense for the years ended December 31, 2020, 2019, and 2018 related to our directors, which is included in other expense on the accompanying consolidated statement of earnings (loss). The income tax benefit recognized in the consolidated statements of earnings (loss) related to this expense was $5.8 million, $6.8 million, and $7.7 million for the years ended December 31, 2020, 2019, and 2018. The amount of unrecognized compensation expense related to all unvested TRSAs and PRSUs as of December 31, 2020 totaled $43.9 million.

Time-Based Restricted Stock Awards

At December 31, 2020, there were 1,608,126 shares of unvested TRSAs outstanding pursuant to the Company's 2003 and 2017 Stock Incentive Plans (the "Plans"). 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. 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.

TRSA grants are subject to "double-trigger" vesting 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 employee for Good Reason, as defined in the Plans, such awards will vest.

The weighted average grant date fair value per share of TRSAs granted during 2020, 2019, and 2018 were $20.84, $38.66, and $53.69. The vesting date fair value of TRSAs that vested during 2020, 2019, and 2018 were $13.1 million, $18.1 million, and $25.9 million.

Performance-Based Restricted Stock Units

At December 31, 2020, there were 315,008 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 and the employee continues to meet the service requirement of the award.

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 2020, 2019, and 2018 was $36.20, $40.39 and $57.52. The vesting date fair value of PRSUs that vested during 2020 and 2019 was $2.7 million and $5.6 million. There were no PRSUs that vested during 2018.

NOTE 20. 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 Programs 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.

The following table shows the dollar amount of shares surrendered, shares surrendered, and weighted average price per share for restricted stock surrendered as treasury shares for the years indicated:

	Year Ended December 31,
Restricted Stock Surrendered as Treasury Shares	2020		2019		2018
Dollar amount of shares surrendered (in thousands)	$	5,369	$	8,449	$	9,149
Number of shares surrendered	213,578		218,531		181,642
Weighted average price per share	$	25.14	$	38.66	$	50.37

Stock Repurchase Programs

The Stock Repurchase Program was initially authorized by PacWest's Board of Directors on October 17, 2016. On February 12, 2020, 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 $200 million. The new Stock Repurchase Program is effective from February 29, 2020 and terminates on February 28, 2021. On April 21, 2020, stock repurchases under the new Stock Repurchase program were suspended indefinitely.

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. All shares repurchased under the various Stock Repurchase Programs were retired upon settlement. At December 31, 2020, the remaining amount that could be used to repurchase shares under the then current Stock Repurchase Program was $200.0 million.

The following table shows the repurchase amounts, shares repurchased, and weighted average price per share for stock repurchases under the various Stock Repurchase Programs for the years indicated:

	Year Ended December 31,
Stock Repurchases Under Stock Repurchase Programs	2020		2019		2018

NOTE 21. 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 DFPI, 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 DFPI 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 DFPI 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. The Bank had a net loss of $256.7 million during the three fiscal years of 2020, 2019, and 2018, compared to dividends of $1.3 billion paid by the Bank during that same period. During 2020, PacWest received $258.0 million in dividends from the Bank. Since the Bank had an accumulated deficit of $2.0 billion at December 31, 2020, for the foreseeable future, dividends from the Bank to PacWest will continue to require DFPI and FDIC approval.

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

Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios of common equity Tier 1, Tier 1, and total capital to risk‑weighted assets ("total capital ratio"), and of Tier I capital to average assets, adjusted for goodwill and other non-qualifying intangible assets and other assets (“leverage ratio”). Common equity Tier 1 capital includes common stockholders’ equity less goodwill and certain other deductions (including a portion of servicing assets and the after‑tax unrealized net gains and losses on securities available‑for‑sale). Tier 1 capital includes common equity Tier 1 plus additional Tier 1 capital instruments meeting certain requirements. Total capital includes Tier 1 capital and other items such as subordinated debt and the allowance for credit losses. All three measures are stated as a percentage of risk‑weighted assets, which are measured based on their perceived credit risk and include certain off‑balance sheet exposures, such as unfunded loan commitments and letters of credit.

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, 2020, such disallowed amounts were $0.2 million for the Company and $16.7 million for the Bank. No assurance can be given that the regulatory capital deferred tax asset limitation will not increase in the future or that the Company or Bank will not have increased deferred tax assets that are disallowed.

Notes to Consolidated Financial Statements

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, 2020, 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, 2020, 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. 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 buffers were 7.0%, 8.5%, and 10.5%. At December 31, 2020, the Company and Bank were in compliance with the capital conservation buffer requirements.

The Company and Bank elected the CECL 5-year regulatory transition guidance for calculating regulatory capital ratios and the December 31, 2020 ratios include this election. This guidance allows an entity to add back to capital 100% of the capital impact from the day one CECL transition adjustment and 25% of subsequent increases to the allowance for credit losses through December 31, 2022. This cumulative amount will then be phased out of regulatory capital over the next three years.

We issued or assumed through mergers subordinated debentures to trusts that were established by us or entities that we previously acquired, which, in turn, issued trust preferred securities. The carrying value of subordinated debentures totaled $465.8 million at December 31, 2020. At December 31, 2020, none of the trust preferred securities were included in the Company's Tier I capital under the phase-out limitations of Basel III, and $451.8 million was included in Tier II capital.

Interest payments on subordinated debentures are considered dividend payments under the FRB regulations and subject to the same notification requirements for declaring and paying dividends on common stock.

NOTE 24. SUBSEQUENT EVENTS

Acquisition of Civic Ventures, LLC

On February 1, 2021, Pacific Western Bank acquired Civic Ventures, LLC and subsidiaries (“Civic”) in an all-cash transaction. The acquisition is not considered significant under SEC regulations. Civic Financial Services is the primary operating entity of Civic. Civic is one of the leading institutional private lenders in the United States specializing in residential non-owner-occupied investment properties. Civic will operate as a wholly-owned subsidiary of the Bank. The acquisition of Civic advances the Bank’s strategy to expand its lending portfolio and diversify its revenue streams.

Common Stock Dividends

On February 17, 2021, the Company announced that the Board of Directors had declared a quarterly cash dividend of $0.25 per common share. The cash dividend is payable on March 10, 2021 to stockholders of record at the close of business on March 1, 2021.

We have evaluated events that have occurred subsequent to December 31, 2020 and have concluded there are no subsequent events that would require recognition in the accompanying consolidated financial statements.

Nature of Operations and Summary of Significant Accounting Policies

NOTE 1.  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 70 full-service branches located in California, one branch located in Durham, North Carolina, one branch located in Denver, Colorado, and numerous loan production offices across the country. The Bank provides community banking products including lending and comprehensive deposit and treasury management services to small and medium-sized businesses conducted primarily through our California-based branch offices and Denver, Colorado branch office. The Bank offers national lending products including asset-based, equipment, and real estate loans and treasury management services to established middle-market businesses on a national basis. The Bank also offers venture banking products including a comprehensive suite of financial services focused on entrepreneurial and venture-backed businesses and their venture capital and private equity investors, with offices located in key innovative hubs across the United States. In addition, we provide investment advisory and asset management services to select clients through Pacific Western Asset Management Inc., a wholly-owned subsidiary of the Bank and an 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 2020

Effective January 1, 2020, the Company adopted ASU 2016-13 and the related amendments to ASC Topic 326, “Financial Instruments - Credit Losses,” to replace the incurred loss accounting approach with a current expected credit loss approach for financial instruments measured at amortized cost and other commitments to extend credit. The new standard is generally intended to require earlier recognition of credit losses. While the standard changes the measurement of the allowance for credit losses, it does not change the credit risk of our lending portfolios or the ultimate losses in those portfolios.

Under the CECL approach, the standard requires immediate recognition of estimated credit losses expected to occur over the estimated remaining life of the asset. The forward-looking concept of CECL requires loss estimates to consider historical experience, current conditions and reasonable and supportable forecasts. The standard modifies the other-than-temporary impairment model for available-for-sale debt securities to require entities to record an allowance when recognizing credit losses for available-for-sale securities, rather than reducing the amortized cost of the securities by direct write-offs.

The Company adopted the new standard using the modified retrospective approach and recognized a cumulative effect adjustment to decrease retained earnings by $5.3 million, net of taxes, and increase the allowance for credit losses by $7.3 million without restating prior periods and applied the requirements of the new standard prospectively. There was no cumulative effect adjustment related to available-for-sale securities at adoption. The Company elected to account for accrued interest receivable separately from the amortized cost of loans and leases and investment securities. Accrued interest receivable is included in "Other assets" on the consolidated balance sheets. The Company elected the practical expedient to use the fair value of the collateral at the reporting date when determining the allowance for credit losses for a financial asset for which the repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty based on the entity’s assessment as of the reporting date (collateral dependent financial asset). Additionally, the Company implemented new business processes, new internal controls, and modified existing and/or implemented new internal models and tools to facilitate the ongoing application of the new standard. See Note 4. Loans and Leases for further details.

Effective January 1, 2020, the Company adopted ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" which simplifies 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. The goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount, and an impairment charge would be recognized 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.

The Company used this approach to evaluate its goodwill during the first quarter of 2020, as an unprecedented decline in economic conditions triggered by the Coronavirus Disease ("COVID-19") pandemic caused a significant decline in stock market valuations in March 2020, including our stock price. These events indicated that goodwill may be impaired and resulted in us performing a goodwill impairment assessment. We applied the market approach using an average share price of the Company's stock and a control premium to determine the fair value of the reporting unit. As a result, a goodwill impairment charge of $1.47 billion was recorded in the first quarter of 2020 as the Company's estimated fair value was less than its book value.

Effective January 1, 2020, the Company adopted the provisions of ASU 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework - Changes to Disclosure Requirements for Fair Value Measurements" which add disclosures regarding changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty. Although the guidance modifies our disclosures in 2020, there was no impact to our consolidated financial statements from the adoption of this new standard.

ASU 2020-03, "Codification Improvements to Financial Instruments" ("ASU 2020-03"), revised a wide variety of topics in the Codification with the intent to make the Codification easier to understand and apply by eliminating inconsistencies and providing clarifications. ASU 2020-03 was effective immediately upon its release in March 2020 and did not have a material impact to our consolidated financial statements.

(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

The Company has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period to prepare these consolidated financial statements in conformity with U.S. GAAP. Actual results could differ from those estimates. Material estimates subject to change in the near term include, among other items, the allowance for credit losses (the combination of the allowance for loan and lease losses and the reserve for unfunded loan commitments), the carrying value of goodwill and other intangible assets, and the realization of deferred tax assets. These estimates may be adjusted as more current information becomes available, and any adjustment may be significant.

(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 venture capital subclasses to better reflect and report our lending. Prior to the realignment, our venture capital subclasses were: (1) equity fund loans, (2) early stage, (3) expansion stage, and (4) late stage. After the realignment, our venture capital subclasses are: (1) equity fund loans and (2) venture lending (which includes early stage, expansion stage, and late stage). All of the loan and allowance tables, both current period and prior periods, reflect this realignment.

(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, (2) interest‑earning deposits in financial institutions, and (3) securities purchased under resale agreements. Interest‑earning deposits in financial institutions represent mostly cash held at the FRBSF, the majority of which is immediately available.

(f) Investment in Debt 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 and 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 value, with unrealized gains or losses reported as a separate component of stockholders’ equity in accumulated other comprehensive income (loss), 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. Such gains or losses are included in "Gain on sale of securities" on the consolidated statements of earnings (loss).

Prior to January 1, 2020, debt securities available-for-sale were measured at fair value and declines in the fair value were reviewed to determine whether the impairment was other-than-temporary. If the decline in fair value was considered temporary, the decline in fair value below the amortized cost basis of a security was recognized in other comprehensive income (loss). If we did not expect to recover the entire amortized cost basis of the security, then an other-than-temporary impairment was considered to have occurred. The cost basis of the security was written down to its estimated fair value and the amount of the write-down was recognized through a charge to earnings. If the amount of the amortized cost basis expected to be recovered increased in a future period, the cost basis of the security was not increased but rather recognized prospectively through interest income.

Effective January 1, 2020, upon the adoption of ASU 2016-13, debt securities available-for-sale are measured at fair value and are subject to impairment testing. A security is impaired if the fair value of the security is less than its amortized cost basis. When an available-for-sale debt security is considered impaired, the Company must determine if the decline in fair value has resulted from a credit-related loss or other factors and then, (1) recognize an allowance for credit losses by a charge to earnings for the credit-related component (if any) of the decline in fair value, and (2) recognize in other comprehensive income (loss) any non-credit related components (if any) of the fair value decline. If the amount of the amortized cost basis expected to be recovered increases in a future period, the valuation allowance would be reduced, but not more than the amount of the current existing allowance for that security.

(g) Equity and Other Investments

Investments in equity securities are classified into one of the following two categories and accounted as follows:

•Securities with a readily determinable fair value are reported at fair value, with changes in fair value recorded in earnings.

•Securities without a readily determinable fair value for which we have elected the "measurement alternative" are reported at cost less impairment (if any) plus or minus adjustments resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer.

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. 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.”

Included in our equity investments that do not have a readily determinable fair value are our investments in non-public Small Business Investment Companies ("SBICs"). All of our SBIC investments meet the definition of investment companies, as defined in ASC 946, Financial Services - Investment Companies. We elected the practical expedient available in Topic 820, Fair Value Measurements, which permits the use of net asset value ("NAV") per share or equivalent to value investments in entities that are or are similar to investment companies. SBICs are required to value and report their investments at estimated fair value. We record the unrealized gains and losses resulting from changes in the fair value of our SBIC investments as gains or losses on equity investments in our consolidated statements of earnings (loss). The carrying value of our SBIC investments is equal to the capital account balance per each SBIC entities' quarterly financial statements.

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."

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 (loss).

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.

(h) 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 primarily 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 to determine if they have experienced a more-than-insignificant deterioration in credit quality since origination or issuance as of the acquisition date and are accounted for as “acquired non‑PCD” or “purchased credit deteriorated” loans.

Acquired non‑PCD loans. Acquired non‑PCD loans are those loans for which there was no evidence of a more-than-insignificant credit deterioration at their acquisition date and it was probable that we would be able to collect all contractually required payments. Acquired non‑PCD loans, together with originated loans, are referred to as Non‑PCD loans. Purchase discounts or premiums on acquired non‑PCD 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 loans with credit deterioration. Prior to January 1, 2020, purchased credit impaired loans were accounted for in accordance with ASC Subtopic 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality.” At the time of acquisition, these loans were recorded at estimated fair value based upon estimated future cash flows with no related allowance for credit losses.

Effective January 1, 2020, upon the adoption of ASU 2016-13, an entity records purchased financial assets with credit deterioration ("PCD assets") at the purchase price plus the allowance for credit losses expected at the time of acquisition. This allowance is recognized through a gross-up that increases the amortized cost basis of the asset with no effect on net income. Subsequent changes (favorable and unfavorable) in expected cash flows are recognized immediately in net income by adjusting the related allowance.

Leases to customers. We provide equipment financing to our customers primarily with direct financing and operating leases. 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 accounting for allowance for loans and leases.

We provide equipment financing through operating leases where we facilitate the purchase of equipment leased to customers. The equipment is shown on our consolidated balance sheets as "Equipment leased to others under operating leases" and is depreciated to its estimated residual value at the end of the lease term, shown as "Leased equipment depreciation" in the consolidated statements of earnings (loss), according to our fixed asset accounting policy. We receive periodic rental income payments under the leases, which are recorded as "Noninterest income" in the consolidated statements of earnings (loss).

Delinquent or past due loans and leases. Loans and leases are considered delinquent when principal or interest payments are past due 30 days or more. Delinquent loans may remain on accrual status between 30 days and 89 days past due.

Nonaccrual loans and leases. When we discontinue the accrual of interest on a loan or lease it is designated as nonaccrual. We discontinue the accrual of interest on a loan 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.

Individually Evaluated Loans and Leases. Loans and leases that do not share similar risk characteristics with other financial assets are individually evaluated for impairment and excluded from loan pools used within the collective evaluation of estimated credit losses. We defined the following criteria for what constitutes a “default”, which results in a loan no longer sharing similar risk characteristics with other loans, and therefore requires an individual evaluation for expected credit losses. The criteria for default may include any one of the following:

•On nonaccrual status,

•Modified under a TDR,

•Payment delinquency of 90 days or more,

•Partial charge-off recognized,

•Risk rated doubtful or loss, or

•Reasonably expected to be modified under a TDR.

Defaulted loans and leases with outstanding balances over $250,000 are reviewed individually for expected credit loss. Individually evaluated loans are measured at the present value of the expected future cash flows discounted at the loan's initial effective interest rate, unless the loans are collateral dependent, in which case loan impairment is based on the estimated fair value of the underlying collateral. A loan is considered collateral-dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the 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. An individually evaluated reserve and/or charge off would be recognized when the present value of expected future cash flows or the fair value of the underlying collateral is below the amortized cost of the loan. If the measured amount of any individually reviewed loan exceeds its amortized cost, further review is required to determine whether a positive allowance should be added (but only up to amounts previously written off) to its amortized cost basis in order to reflect the net amount expected to be collected.

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.

The Company has granted various commercial and consumer loan modifications to provide borrowers relief from the economic impacts of COVID-19. In accordance with the Coronavirus Aid, Relief, and Economic Security ("CARES") Act, the Company elected to not apply TDR classification to COVID-19 related loan modifications that met all of the requisite criteria as stipulated in the CARES Act.

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. Loan modifications that qualify as troubled debt restructurings are individually evaluated for expected credit losses 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.

Impaired loans and leases. Prior to January 1, 2020, a loan or lease was considered impaired when it was probable that we would be unable to collect all amounts due according to the contractual terms of the loan or lease agreement. Impaired loans and leases included loans and leases on nonaccrual status and performing troubled debt restructured loans. Income from impaired loans was recognized on an accrual basis unless the loan was on nonaccrual status. Income from loans on nonaccrual status was recognized to the extent cash was received and when the loan’s principal balance was deemed collectable. We measured 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 was 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 was not collateral‑dependent. The impairment amount on a collateral‑dependent loan or lease was charged‑off, and the impairment amount on a loan that was not collateral‑dependent was generally recorded as a specific reserve within our allowance for loan and lease losses.

(i) Allowance for Credit Losses on Loans and Leases Held for Investment

Effective January 1, 2020, upon the adoption of ASU 2016-13, the Company replaced the incurred loss accounting approach with the current expected credit loss ("CECL") approach for financial instruments measured at amortized cost and other commitments to extend credit. CECL requires the immediate recognition of estimated credit losses expected to occur over the estimated remaining life of the asset. The forward-looking concept of CECL requires loss estimates to consider historical experience, current conditions and reasonable and supportable forecasts.

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 the amortized cost basis of loans and leases, while the reserve for unfunded loan commitments is included within "Accrued interest payable and other liabilities" on the consolidated balance sheets. The amortized cost basis of loans and leases does not include accrued interest receivable, which is included in "Other assets" on the consolidated balance sheets. The "Provision for credit losses" on the consolidated statements of earnings (loss) is a combination of the provision for loan and lease losses and the provision for unfunded loan commitments.

Under the CECL methodology, expected credit losses reflect losses over the remaining contractual life of an asset, considering the effect of prepayments and available information about the collectability of cash flows, including information about relevant historical experience, current conditions, and reasonable and supportable forecasts of future events and circumstances. Thus, the CECL methodology incorporates a broad range of information in developing credit loss estimates. The resulting allowance for loan and lease losses is deducted from the associated amortized cost basis to reflect the net amount expected to be collected. Subsequent changes in this estimate are recorded through the provision for credit losses and the allowance. The CECL methodology could result in significant changes to both the timing and amounts of provision for credit losses and the allowance as compared to historical periods. Loans and leases that are deemed to be uncollectable are charged off and deducted from the allowance. The provision for credit losses and recoveries on loans and leases previously charged off are added to the allowance.

The allowance for loan and lease losses is comprised of an individually evaluated component for loans and leases that no longer share similar risk characteristics with other loans and leases and a pooled loans component for loans and leases that share similar risk characteristics.

A loan or lease with an outstanding balance greater than $250,000 is individually evaluated for expected credit loss when it is probable that we will be unable to collect all amounts due according to the original contractual terms of the agreement. We select loans and leases for individual assessment on an ongoing basis using certain criteria such as payment performance, borrower reported and forecasted financial results, and other external factors when appropriate. We measure the current expected credit loss of an individually evaluated 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 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.

Our CECL methodology for the pooled loans component includes both quantitative and qualitative loss factors which are applied to our population of loans and leases and assessed at a pool level. The quantitative CECL model estimates credit losses by applying pool-specific probability of default ("PD") and loss given default ("LGD") rates to the expected exposure at default ("EAD") over the contractual life of loans and leases. The qualitative component considers internal and external risk factors that may not be adequately assessed in the quantitative model.

The loan portfolio is segmented into four loan segments, eight loan classes, and 19 loan pools (excluding Paycheck Protection Program loans, which are fully government guaranteed) based upon loan type that share similar default risk characteristics to calculate quantitative loss factors for each pool. Three of these loan pools have insignificant current balances and/or insignificant historical losses, thus, estimated losses are calculated using historical loss rates from the first quarter of 2009 to the current period rather than econometric regression modeling. For the remaining 16 loan pools, we estimate the PD during the reasonable and supportable forecast period using seven econometric regression models developed to correlate macroeconomic variables to historical credit performance (based on quarterly transition matrices from 2009 to 2019, which include risk rating upgrades/downgrades and defaults).

The loans and unfunded commitments are grouped into nine LGD pools based on portfolio classes that share similar collateral risk characteristics. LGD rates are computed based on the net charge-offs recognized divided by the EAD of defaulted loans starting with the first quarter of 2009 to the current period. The PD and LGD rates are applied to the EAD at the loan or lease level based on contractual scheduled payments and estimated prepayments. We use our actual historical loan prepayment experience from 2009 to 2019 to estimate future prepayments by loan pool. Loans and leases with outstanding balances less than or equal to $250,000, where it is probable that we will be unable to collect all amounts due according to the contractual terms of the agreement, remain in their respective pools and are assigned a 100% probability of default.

For the reasonable and supportable forecast period, future macroeconomic events and circumstances are estimated over a 4-quarter time horizon using a single scenario economic forecast that is consistent with management's current expectations for the 16 loan pools. We use economic forecasts from Moody's Analytics in this process. The economic forecast is updated monthly; therefore, the one used for each quarter-end calculation is generally released a few weeks prior to quarter-end. If economic conditions as of the balance sheet date change materially, management would consider a qualitative adjustment. The key macroeconomic assumptions used in each of the seven PD regression models include two or three of the following economic indicators: Real GDP, unemployment rates, CRE Price Index, the BBB corporate spread, nominal disposable income, and CPI.

The quantitative CECL model applies the projected rates based on the economic forecasts for the 4-quarter reasonable and supportable forecast horizon to EAD to estimate defaulted loans. During this forecast horizon, prepayment rates during a historical period that exhibits economic conditions most similar to the economic forecast are used to estimate EAD. If no historical period from 2009 to 2019 exhibits economic conditions that are similar to the economic forecast, management uses its best estimate of prepayments expected over the reasonable and supportable forecast period which may, in some circumstances, be the average of all historical prepayment experience. Historical LGD rates are applied to estimated defaulted loans to determine estimated credit losses. We then use a 2-quarter reversion period to revert on a straight-line basis from the PD, LGD, and prepayment rates used during the reasonable and supportable forecast period to the Company’s historical PD, LGD, and prepayment experience. Subsequent to the reversion period for the remaining contractual life of loans and leases, the PD, LGD, and prepayment rates are based on historical experience from 2009 to 2019. PD regression models and prepayment rates are updated on an annual basis. LGD rates are updated every quarter to reflect current charge-off activity.

The PDs calculated by the quantitative models are highly correlated to our internal risk ratings assigned to each loan and lease. 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 and leases on a regular basis. The credit risk ratings assigned to every loan and lease are as follows:

•High Pass: (Risk ratings 1-2) Loans and leases rated as "high pass" exhibit a favorable credit profile and have minimal risk characteristics. Repayment in full is expected, even in adverse economic conditions.

•Pass: (Risk ratings 3-4) Loans and leases rated as "pass" are not adversely classified and collection and repayment in full are expected.

•Special Mention: (Risk rating 5) 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.

•Substandard: (Risk rating 6) 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.

•Doubtful: (Risk rating 7) 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.

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 4. Loans and Leases.

In addition to our internal risk rating process, our federal and state banking regulators, as an integral part of their examination process, periodically review the Company’s loan and lease risk rating classifications. Our regulators may require the Company to recognize rating downgrades based on 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.

The qualitative portion of the reserve on pooled loans and leases represents management’s judgment of additional considerations to account for internal and external risk factors that are not adequately measured in the quantitative reserve. The qualitative loss factors consider idiosyncratic risk factors, conditions that may not be reflected in quantitatively derived results, or other relevant factors to ensure the allowance for credit losses reflects our best estimate of current expected credit losses. Current and forecasted economic trends and underlying market values for collateral dependent loans are generally considered to be encompassed within the CECL quantitative reserve. An incremental qualitative adjustment may be considered when economic forecasts exhibit higher levels of volatility or uncertainty.

In addition to economic conditions and collateral dependency, the other qualitative criteria we consider when establishing the loss factors include the following:

•Legal and Regulatory - matters that could impact our borrowers’ ability to repay our loans and leases;

•Concentrations - loan and lease portfolio composition and any loan concentrations;

•Lending Policy - current lending policies and the effects of any new policies or policy amendments;

•Nature and Volume - loan and lease production volume and mix;

•Problem Loan Trends - loan and lease portfolio credit performance trends, including a borrower's financial condition, credit rating, and ability to meet loan payment requirements;

•Loan Review - results of independent credit review; and

•Management - changes in management related to credit administration functions.

We estimate the reserve for unfunded loan commitments using the same PD, LGD, and prepayment rates for the quantitative credit losses and qualitative loss factors as used for the allowance for loan and lease losses. The EAD for the reserve for unfunded loan commitments is computed using expected future utilization rates of the unfunded commitments during the contractual life of the commitments based on historical usage by loan pool from 2015 to 2019. The utilization rates are updated on an annual basis.

The CECL methodology requires a significant amount of management judgment in determining the appropriate allowance for credit losses. Most of the steps in the methodology involve judgment and are subjective in nature including, among other things: segmenting the loan and lease portfolio; determining the amount of loss history to consider; selecting predictive econometric regression models that use appropriate macroeconomic variables; determining the methodology to forecast prepayments; selecting the most appropriate economic forecast scenario; determining the length of the reasonable and supportable forecast and reversion periods; estimating expected utilization rates on unfunded loan commitments; and assessing relevant and appropriate qualitative factors. In addition, the CECL methodology is dependent on economic forecasts which are inherently imprecise and will change from period to period. Although the allowance for credit losses is considered appropriate, there can be no assurance that it will be sufficient to absorb future losses.

Management believes the allowance for credit losses is appropriate for the current expected credit losses in our loan and lease portfolio and associated unfunded commitments, and the credit risk ratings and inherent loss rates currently assigned are reasonable and appropriate as of the reporting date. 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 consolidated financial statements.

Prior to January 1, 2020, the allowance for loan losses was measured using the incurred loss accounting approach. The allowance for credit losses was 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 was 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.

The allowance for loan and lease losses had a general reserve component for unimpaired loans and leases and a specific reserve component for impaired loans and leases.

A loan or lease was considered impaired when it was probable that we would be unable to collect all amounts due according to the original contractual terms of the agreement. We assessed 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 measured impairment of a loan or lease based upon the fair value of the underlying collateral if the loan or lease was collateral-dependent or the present value of cash flows, discounted at the effective interest rate, if the loan or lease was not collateral-dependent. To the extent a loan or lease balance exceeded the estimated collectable value, a specific reserve or charge-off was recorded depending upon either the certainty of the estimate of loss or the fair value of the loan’s collateral if the loan was collateral-dependent. Impaired loans and leases with outstanding balances less than or equal to $250,000 might not be individually assessed for impairment but would be 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 included both quantitative and qualitative loss factors which were applied to our population of unimpaired loans and leases to estimate our general reserves. The quantitative loss factors determination was based on a probability of default/loss given default ("PD/LGD") methodology which considered 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 had higher quantitative loss factors. The qualitative loss factors considered, among other things, current economic trends and forecasts, current collateral values and performance trends, credit performance trends, and the loan portfolio's current composition.

The quantitative estimation of the allowance for credit losses considered actual historical loan and lease charge-off experience over a 44-quarter look-back period starting with the first quarter of 2009. This look-back period was inclusive of the average timeframe over which charge-offs typically occurred following loan or lease origination and allowed for the capture of sufficient loss observations that were relevant to the current portfolio. When estimating the general reserve component for the various pools of similar loan types, the loss factors applied to the loan pools considered the current credit risk ratings, giving greater weight to loans with more adverse credit risk ratings. We recognized that the determination of the allowance for credit losses was sensitive to the assigned credit risk ratings and inherent loss rates at any given point in time.

(j) Land, Premises and Equipment

Premises and equipment are stated at cost less accumulated depreciation and amortization. Land is not depreciated. Depreciation and amortization is charged to "Noninterest expense" in the consolidated statements of earnings (loss) 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.

(k) 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 (loss) 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."

(l) Income Taxes

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

On a periodic 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.

(m) 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 annually unless a triggering event occurs thereby requiring an updated assessment. Our regular annual impairment assessment occurs in the fourth quarter. Goodwill represents the excess of the purchase price over the fair value of the net assets and other identifiable intangible assets acquired. Impairment exists when the carrying value of the goodwill exceeds its 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 (loss).

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 amount would be recognized as a charge to "Noninterest expense" in the consolidated statements of earnings (loss).

(n) Operating Leases

As of December 31, 2020, the Company only had operating leases related to our leased facilities. The Company determines if an arrangement is a lease at inception by assessing whether there is an identified asset and whether the contract conveys the right to control the use of the identified asset for a period of time in exchange for consideration. Operating leases with a term of more than one year are included in operating lease ROU assets and operating lease liabilities, which are reported in "Other assets" and "Accrued interest payable and other liabilities" on the Company's consolidated balance sheets. The Company made a policy election to apply the short-term lease exemption to any operating leases with an original term of less than 12 months, therefore no ROU asset or lease liability is recorded for these operating leases. The Company has agreements with lease and non-lease components, which are accounted for as a single lease component.

ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized on the lease commencement date based on the present value of lease payments over the lease term. The Company uses the incremental borrowing rate commensurate with the lease term based on the information available at the lease commencement date in determining the present value of lease payments. ROU assets initially equal the lease liability, adjusted for any prepaid lease payments and initial direct costs incurred less any lease incentives received.

Certain of the Company's lease agreements include rental payments that adjust periodically based on changes in the CPI. We initially measure the present value of the lease payments using the index at the lease commencement date. Subsequent increases in the CPI are treated as variable lease payments and recognized in the period in which the obligation for those payments is incurred. The ROU assets and lease liabilities are not re-measured as a result of changes in the CPI. The Company's lease terms may include options to extend or terminate the lease. These options to extend or terminate are assessed on a lease-by-lease basis, and the ROU assets and lease liabilities are adjusted when it is reasonably certain that an option will be exercised. Rent expense for lease payments is recognized on a straight-line basis over the lease term and is included in "Occupancy expense" on the Company's consolidated statements of earnings (loss).

The Company uses the long-lived assets impairment guidance under ASC Topic 360-10-35, "Property, Plant and Equipment," to determine whether an ROU asset is impaired, and if impaired, the amount of loss to recognize. Long-lived assets are tested for recoverability whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. These could include vacating the leased space, obsolescence, or physical damage to a facility. Under ASC Topic 842, "Leases," if an impairment loss is recognized for a ROU asset, the adjusted carrying amount of the ROU asset would be its new accounting basis. The remaining ROU asset (after the impairment write-down) is amortized on a straight-line basis over the remaining lease term.

(o) 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 and the employee continues to meet the service requirement of the award.

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 only paid 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.

(p) Derivative Instruments

The Company uses derivatives to manage exposure to market risk, primarily foreign currency risk and interest rate risk, and to assist customers with their risk management objectives. The Company uses foreign exchange contracts to manage the foreign exchange rate risk associated with certain foreign currency-denominated assets and liabilities. As of December 31, 2020, 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 foreign currency derivatives are carried at fair value and 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 (loss).

The Bank offers interest rate swap products to certain loan customers to allow them to hedge the risk of rising interest rates on their variable rate loans. When such products are issued, we also enter into an offsetting swap with institutional counterparties to eliminate the interest rate risk to us. These back-to-back swap agreements, which generate fee income for us, are intended to offset each other. We retain the credit risk of the original loan. The net cash flow for us is equal to the interest income received from a variable rate loan originated with the client plus a fee. These swaps are not designated as accounting hedges and are recorded at fair value in "Other assets" and "Accrued interest payable and other liabilities" in the consolidated balance sheets. The changes in fair value are recorded in "Noninterest income - other" in the consolidated statements of earnings (loss).

In connection with negotiated credit facilities and certain other services, we may obtain equity warrant assets giving us the right to acquire stock in primarily private, venture-backed companies. We account for equity warrant assets as derivatives when they contain net settlement terms and other qualifying criteria under ASC 815. These equity warrant assets are measured at estimated fair value on a monthly basis and are classified as "Other assets" in the consolidated balance sheets at the time they are obtained.

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.

(q) Comprehensive Income (Loss)

Comprehensive income (loss) 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 (loss).

(r) Earnings (Loss) 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 (loss) 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 (loss) to determine that amount of earnings (loss) available to common stockholders. In the two‑class method, the amount of our earnings (loss) available to common stockholders is divided by the weighted average shares outstanding, excluding any unvested restricted stock, for both the basic and diluted earnings (loss) per share.

(s) 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 consolidated statements of earnings (loss) from the date of acquisition. Acquisition‑related costs, including conversion and restructuring charges, are expensed as incurred.

(t) 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, 2020 and since December 31, 2015, we operated as one reportable segment. The factors considered in making this determination include the nature of products and offered services, geographic regions in which we operate, the applicable regulatory environment, and the discrete financial information reviewed by our key decision makers. Through our network of banking offices nationwide, our entire operations provide relationship-based banking products, services and solutions for small to mid-sized companies, entrepreneurial and venture-backed 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.

The securities that were in an unrealized loss position at December 31, 2020, were considered impaired and required further review to determine if the unrealized losses were credit-related. We 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. We also considered the seniority of the tranches and U.S. government agency guarantees, if any, to assess whether an unrealized loss was credit-related. Accordingly, we determined the unrealized losses were not credit-related and recognized the unrealized losses in "other comprehensive income" in stockholders' equity. Although we periodically sell securities for portfolio management purposes, we do not foresee having to sell any impaired securities strictly for liquidity needs and believe that it is more likely than not we would not be required to sell any impaired securities before recovery of their amortized cost.

Contractual Maturities of Securities Available-for-Sale

The following table presents the contractual maturities of our available-for-sale securities portfolio based on amortized cost and carrying value as of the date indicated.

	December 31, 2020
	Amortized		Fair
Maturity	Cost		Value
	(In thousands)
Due in one year or less	$	6,063	$	6,091
Due after one year through five years	575,561		606,388
Due after five years through ten years	1,306,179		1,368,746
Due after ten years	3,109,167		3,254,366
Total securities available-for-sale	$	4,996,970	$	5,235,591

MBS and CMOs have contractual maturity dates, but require periodic payments based upon scheduled amortization terms. Actual principal collections on these securities usually occur more rapidly than the scheduled amortization terms because of prepayments made by obligors of the underlying loan collateral.

FHLB Stock

In connection with outstanding FHLB advances, the Bank owned FHLB stock carried at cost of $17.3 million and $40.9 million at December 31, 2020 and 2019. At December 31, 2020 and 2019, the Bank was required to own FHLB stock equal to a percentage of outstanding FHLB advances. During the year ended December 31, 2020, FHLB stock decreased by $23.7 million due mainly to $68.5 million in redemptions, offset partially by $44.8 million in purchases. We evaluated the carrying value of our FHLB stock investment at December 31, 2020 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.

TDRs are a result of rate reductions, term extensions, fee concessions, transfers to foreclosed assets, discounted loan payoffs, and debt forgiveness, or a combination thereof. The Company has granted various commercial and consumer loan modifications to provide borrowers relief from the economic impacts of COVID-19. In accordance with the CARES Act, the Company elected to not apply TDR classification to COVID-19 related loan modifications that met all of the requisite criteria as stipulated in the CARES Act.

(1)     The population of defaulted TDRs for the period indicated includes only those loans restructured during the preceding 12-month period. For example, for the year ended December 31, 2020, the population of defaulted TDRs includes only those loans restructured after December 31, 2019. The table excludes defaulted TDRs in those classes for which the recorded investment was zero at the end of the period.

(2)     One commercial asset-based loan with a pre-modification balance of $27.3 million and a post-modification balance of $32.3 million was previously restructured in December 2017.

At December 31, 2020 and 2019, we had unfunded commitments related to TDRs of $0.9 million and $1.2 million.

Leases Receivable

We provide equipment financing to our customers primarily with operating and direct financing leases. For direct financing leases, lease receivables are recorded on the balance sheet but the leased equipment is not, although we generally retain legal title to the leased equipment 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. Direct financing leases are subject to our accounting for allowance for loan and lease losses. See Note 9. Leases for information regarding operating leases where we are the lessor.

The allowance for loan and lease losses increased by $209.4 million in 2020 due primarily to a provision for loan and lease losses of $293.0 million. The higher provision for loan and lease losses in 2020 was primarily a result of the impact of the current economic forecast used in our ACL estimation, which reflected a significant deterioration in key macro-economic forecast variables such as unemployment and Real GDP as a result of the COVID-19 pandemic, significant loan downgrades into special mention, and higher provisions on individually evaluated loans.

We actively participated in the Paycheck Protection Program ("PPP"), under the provisions of the CARES Act during the second quarter of 2020. As of December 31, 2020, PPP loans had an outstanding balance of approximately $1.1 billion. The loans have two or three year terms, are fully guaranteed by the SBA, and do not carry an allowance.

A loan is considered collateral-dependent, and is individually evaluated for reserve purposes, when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral.

Goodwill and Other Intangible Assets, Net

NOTE 7.  GOODWILL AND OTHER INTANGIBLE ASSETS, NET

The unprecedented decline in economic conditions triggered by the COVID-19 pandemic caused a significant decline in stock market valuations in March 2020, including our stock price. These triggering events indicated that goodwill related to our single reporting unit may be impaired and resulted in us performing a goodwill impairment assessment in the first quarter of 2020. We applied the market approach using an average share price of the Company's stock and a control premium to determine the fair value of the reporting unit. The control premium was based upon management judgment using historical information of control premiums for completed bank acquisitions. As a result, we recorded a goodwill impairment charge of $1.47 billion in the first quarter of 2020 as the estimated fair value of equity was less than book value. This was a non-cash charge to earnings and had no impact on our regulatory capital ratios, cash flows, or liquidity position.

In performing our annual goodwill assessment in the fourth quarter of 2020, we considered relevant events and circumstances that may affect the fair value or carrying amount of our reporting unit. The events and circumstances we considered included macroeconomic conditions, industry conditions, and our financial performance. Based on our qualitative assessment, we concluded that there were no conditions, changes in operations, or results that indicated a triggering event had occurred in the fourth quarter of 2020. Thus, a quantitative assessment was not required and we determined that it was more likely than not that the fair value of the reporting unit was greater than its carrying value and there was no evidence of impairment.

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

	Goodwill

Balance, December 31, 2019	$	2,548,670
Impairment	(1,470,000)
Balance, December 31, 2020	$	1,078,670

Our other intangible assets with definite lives are CDI and CRI. CDI and CRI are amortized over their respective estimated useful lives and reviewed for impairment at least quarterly. The amortization expense represents the estimated decline in the value of the underlying deposits or customer relationships acquired.

(1)    During the first quarter of 2020, the Company increased the amount of its investment in low income housing project partnerships by $101 million representing the amount of related unfunded commitments, with an offset to a liability included in "Accrued interest payable and other liabilities" on the consolidated balance sheets.

(2)    See Note 9. Leases for further details regarding the operating lease ROU assets.

(3)    During the third quarter of 2020, the Company prospectively changed the accounting method for its SBIC investments from modified cost to NAV fair value.

(4)    For information regarding equity warrants, see Note 12. Derivatives.

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 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 in excess of the cash surrender value are recorded to "Noninterest income - other."

The Company's equity investments without readily determinable fair values include investments in privately held companies, limited partnerships, entities from which we issued trust preferred securities, CRA-related loan pool investments, and CRA-related equity investments. The CRA-related loan pool and 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. We measure our equity investments without readily determinable fair values using the measurement alternative. Carrying values of these investments are adjusted to fair value upon observable transactions for identical or similar investments of the same issuer. Unrealized and realized gains and losses on equity investments without readily determinable fair values are recorded in "Noninterest income - other" on the consolidated statements of earnings (loss).

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. Unrealized and realized gains and losses on equity investments with readily determinable fair values are recorded in "Noninterest income - other"

Leases [Abstract]

Leases

NOTE 9. LEASES

We determine if an arrangement is a lease at inception by assessing whether there is an identified asset, and whether the contract conveys the right to control the use of the identified asset for a period of time in exchange for consideration. ASC Topic 842 also requires a lessee to classify a lease as either finance or operating.

ROU assets represent a lessee's right to use an underlying asset for the lease term and lease liabilities represent a lessee's obligation to make lease payments arising from the lease. We amortize the operating lease ROU assets and record interest expense on the operating lease liabilities over the lease terms.

Operating leases with a term of more than one year are included in operating lease ROU assets and operating lease liabilities, which are reported in "Other assets" and "Accrued interest payable and other liabilities" on the Company's consolidated balance sheets. Short-term leases (initial term of less than 12 months) are not recorded on the balance sheet and lease expense is recognized on a straight-line basis over the lease term. We have lease agreements with lease and non-lease components, which are accounted for as a single lease component. Most leases include one or more options to renew, with renewal terms that can extend the lease from one to ten years. The exercise of lease renewal options is at our sole discretion. Some of our leases also include termination options. We have determined that we do not meet the reasonably certain threshold to exercise any renewal or termination options, therefore our lease terms do not reflect any optional periods. We rent or sublease certain office space to third parties. Our subleases consist of operating leases for offices that we have fully or partially vacated.

Certain of our lease agreements also include rental payments that adjust periodically based on changes in the CPI. We initially measured our lease payments using the index at the lease commencement date. Subsequent increases in the CPI are treated as variable lease payments and recognized in the period in which the obligation for those payments is incurred. The ROU assets and lease liabilities are not re-measured as a result of changes in the CPI. Our lease agreements do not contain any purchase options, residual value guarantees, or restrictive covenants.

Operating Leases as a Lessor

We provide equipment financing to our customers through operating leases where we facilitate the purchase of equipment leased to our customers. The equipment is shown on our consolidated balance sheets as "Equipment leased to others under operating leases" and is depreciated to its estimated residual value at the end of the lease term, shown as "Leased equipment depreciation" in the consolidated statements of earnings (loss), according to our fixed asset accounting policy. We receive periodic rental income payments under the leases, which are recorded as "Leased equipment income" in the consolidated statements of earnings (loss). The equipment is tested periodically for impairment. No impairment was recorded on "Equipment leased to others under operating leases" for the years ended December 31, 2020 and 2019.

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

FHLB Secured Line of Credit. The Bank had secured borrowing capacity with the FHLB of $3.3 billion as of December 31, 2020, collateralized by a blanket lien on $5.6 billion of qualifying loans. During the second quarter of 2020, the Company prepaid $750.0 million of FHLB term advances borrowed in the first quarter of 2020 and incurred $6.6 million of prepayment penalties, which is included in "Other expense" on the consolidated statements of earnings (loss). The FHLB term advances had a weighted average interest rate of 0.96% and the prepayment decision was made after the significant drop in market interest rates in March 2020 and the expectation of continued low interest rates for an extended time.

The following table presents the interest rates and maturity dates of FHLB secured advances as of the dates indicated:

FHLB Unsecured Line of Credit. As of December 31, 2020, the Bank had a $112.0 million unsecured line of credit with the FHLB for the borrowing of overnight funds, of which none was outstanding. As of December 31, 2019, the balance outstanding was $141.0 million.

Federal Funds Arrangements with Commercial Banks. As of December 31, 2020, the Bank had unsecured lines of credit of $180.0 million in the aggregate with several correspondent banks for the borrowing of overnight funds, subject to availability of funds. These lines are renewable annually and have no unused commitment fees. As of December 31, 2020 and 2019, there were no balances outstanding. 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, 2020, there was no borrowing. As of December 31, 2019, there were $300.0 million in overnight borrowings outstanding.

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 and receive approval from 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. 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. Since the impact of the goodwill impairment charge on net earnings in the first quarter of 2020, we are required to receive approval from the FRB prior to declaring a dividend until such time the applicable regulations no longer require such approval.

DERIVATIVES

The Company uses derivatives to manage exposure to market risk, primarily foreign currency risk and interest rate risk, and to assist customers with their risk management objectives. Our derivatives are carried at fair value and recorded in "Other assets" or "Accrued interest payable and other liabilities," as appropriate, in the consolidated balance sheets. The changes in fair value of our derivatives and the related fees are recognized in "Noninterest income - other" in the consolidated statements of earnings (loss). For the year ended December 31, 2020, changes in fair value and fees recorded to noninterest income in the consolidated statements of earnings (loss) were immaterial. See Note 8. Other Assets for additional information regarding equity warrant assets.

The following table presents the U.S. dollar notional amounts and fair values of our derivative instruments included in the consolidated balance sheets as of the dates indicated:

____________________________

(1)    During the first quarter of 2020, the Company increased the amount of its investment in low income housing project partnerships by $101 million representing the amount of related unfunded commitments, with an offset to a liability included in "Accrued interest payable and other liabilities" on the consolidated balance sheets.

The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit 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 several of our lending arrangements and property lease obligations. Most guarantees expire within one year from the date of issuance. If a borrower defaults on its commitments subject to any letter of credit issued under these arrangements, we would be required to meet the borrower's financial obligation but would seek repayment of that financial obligation from the borrower. In some cases, borrowers have pledged cash and investment securities as collateral under these arrangements.

Additionally, we have commitments to invest in SBICs that call for capital contributions up to an amount specified in the partnership agreements, and in CRA-related loan pools. As of December 31, 2020, such commitments totaled $55.5 million. As of December 31, 2019, in addition to commitments for SBICs and CRA-related loan pools, we also had commitments to invest in low income housing projects that provide income tax credits. Total commitments to these entities totaled $129.2 million. We also had commitments to contribute up to an additional $50,000 to private equity funds at December 31, 2019.

The following table presents the years in which commitments are expected to be paid for our commitments to contribute capital to SBICs and CRA-related loan pools as of the date indicated:

	December 31, 2020

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. The range of any reasonably possible liabilities is also not significant.

Fair Value Disclosures [Abstract]

Fair Value Measurements

NOTE 14.  FAIR VALUE MEASUREMENTS

ASC Topic 820, “Fair Value Measurement,” defines fair value, establishes a framework for measuring fair value including a three‑level valuation hierarchy, and expands disclosures about fair value measurements. Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date reflecting assumptions that a market participant would use when pricing an asset or liability. The hierarchy uses three levels of inputs to measure the fair value of assets and liabilities as follows:

•Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets.

•Level 2: Observable inputs other than Level 1, including quoted prices for similar assets and liabilities in active markets, quoted prices in less active markets, or other observable inputs that can be corroborated by observable market data, either directly or indirectly, for substantially the full term of the financial instrument. This category generally includes agency residential CMOs, agency commercial and residential MBS, municipal securities, collateralized loan obligations, registered publicly rated private label CMOs, corporate debt securities, SBA securities, and asset-backed securitizations.

•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 individually evaluated loans and leases and other real estate owned and also to record impairment on certain assets, such as goodwill, CDI, and other long-lived assets.

The Company also holds SBIC investments measured at fair value using the NAV per share practical expedient that are not required to be classified in the fair value hierarchy. At December 31, 2020, the fair value of these investments was $32.3 million.

The following tables present information on the assets and liabilities measured and recorded at fair value on a recurring basis as of the dates indicated:

The following is a description of the valuation methodologies used to measure our assets recorded at fair value (under ASC Topic 820, “Fair Value Measurement”) and for estimating fair value for financial instruments not recorded at fair value (under ASC Topic 825).

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 3. 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.

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. Had significant changes in default expectations, loss severity factors, or discount rates occurred all together or in isolation, it would have resulted in different fair value measurements at December 31, 2020.

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 measured using the exit price and 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. The Community Bank group originates and purchases a number of similar, homogeneous loans. For this portfolio, management may make adjustments to the discount rate arrived at using the previously described methodology based upon the pricing for recent loan pool purchases and/or rates on recent originations.

Individually evaluated loans and leases. Defaulted loans and leases with outstanding balances over $250,000 are reviewed individually for expected credit loss, if any, and are recorded at fair value on a non-recurring basis. These defaulted loans and leases are excluded from the loan pools used within the collective evaluation of estimated credit losses.

To the extent a defaulted loan or lease is collateral dependent, we measure expected credit loss 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, 2020.

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 individually evaluated loans and leases 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 individually evaluated loan and lease balances shown above as measured on a non-recurring basis represent those defaulted loans and leases for which expected credit loss was recognized during the year ended December 31, 2020. The amounts shown as net losses include the expected credit loss recognized during the year ended December 31, 2020, for the loan and lease balances shown.

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, 2020.

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. We typically classify our equity warrant derivatives in Level 3 of the fair value hierarchy.

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.” 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.

Limitations

Fair value estimates are made at a specific point in time and are based on relevant market information and information about the financial instrument. These estimates do not reflect income taxes or any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a portion of the Company’s financial instruments, fair value estimates are based on what management believes to be reasonable judgments regarding expected future cash flows, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimated fair values are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Since the fair values have been estimated as of December 31, 2020, the amounts that will actually be realized or paid at settlement or maturity of the instruments could be significantly different.

Revenue From Contracts With Customers Revenue From Contracts With Customers (Notes)

Revenue From Contracts With Customers [Abstract]

Revenue From Contracts With Customers

REVENUE FROM CONTRACTS WITH CUSTOMERS

Revenue from contracts with customers 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. Such 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, 2020.

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 ASC 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:

•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.

•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.

Disaggregation of Revenue

The following table presents interest income and noninterest income, the components of total revenue, as disclosed in the consolidated statements of earnings (loss) and the related amounts which are from contracts with customers within the scope of ASC Topic 606. As illustrated here, substantially all of our revenue is specifically excluded from the scope of ASC Topic 606.

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, 2020, there were 1,734,014 shares available for grant under the 2017 Plan. Though frozen for new issuances, certain awards issued under the 2003 Stock Incentive Plan remain outstanding, and are due to vest no later than February 2021.

Restricted stock amortization totaled $23.7 million, $26.2 million, and $29.1 million for the years ended December 31, 2020, 2019, and 2018. Such amounts are included in compensation expense on the accompanying consolidated statements of earnings (loss) and exclude $627,000, $598,000, and $627,000 of stock-based compensation expense for the years ended December 31, 2020, 2019, and 2018 related to our directors, which is included in other expense on the accompanying consolidated statement of earnings (loss). The income tax benefit recognized in the consolidated statements of earnings (loss) related to this expense was $5.8 million, $6.8 million, and $7.7 million for the years ended December 31, 2020, 2019, and 2018. The amount of unrecognized compensation expense related to all unvested TRSAs and PRSUs as of December 31, 2020 totaled $43.9 million. Such expense is expected to be recognized over a weighted average period of 1.4 years.

The following table presents a summary of restricted stock transactions during the year ended December 31, 2020:

	TRSAs		PRSUs
		Weighted		Weighted
		Average		Average

Unvested restricted stock, end of year	1,608,126	$32.83	315,008	$42.77

The table above excludes 37,357 of immediately vested shares awarded to our directors at a weighted average price of $16.78.

Time-Based Restricted Stock Awards

At December 31, 2020, there were 1,608,126 shares of unvested TRSAs outstanding pursuant to the Company's 2003 and 2017 Stock Incentive Plans (the "Plans"). 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. 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.

TRSA grants are subject to "double-trigger" vesting 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 employee for Good Reason, as defined in the Plans, such awards will vest.

The weighted average grant date fair value per share of TRSAs granted during 2020, 2019, and 2018 were $20.84, $38.66, and $53.69. The vesting date fair value of TRSAs that vested during 2020, 2019, and 2018 were $13.1 million, $18.1 million, and $25.9 million.

Performance-Based Restricted Stock Units

At December 31, 2020, there were 315,008 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 and the employee continues to meet the service requirement of the award.

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 2020, 2019, and 2018 was $36.20, $40.39 and $57.52. The vesting date fair value of PRSUs that vested during 2020 and 2019 was $2.7 million and $5.6 million. There were no PRSUs that vested during 2018.

Stockholders' Equity

NOTE 20. 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 Programs 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.

The following table shows the dollar amount of shares surrendered, shares surrendered, and weighted average price per share for restricted stock surrendered as treasury shares for the years indicated:

	Year Ended December 31,
Restricted Stock Surrendered as Treasury Shares	2020		2019		2018
Dollar amount of shares surrendered (in thousands)	$	5,369	$	8,449	$	9,149
Number of shares surrendered	213,578		218,531		181,642
Weighted average price per share	$	25.14	$	38.66	$	50.37

Stock Repurchase Programs

The Stock Repurchase Program was initially authorized by PacWest's Board of Directors on October 17, 2016. On February 12, 2020, 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 $200 million. The new Stock Repurchase Program is effective from February 29, 2020 and terminates on February 28, 2021. On April 21, 2020, stock repurchases under the new Stock Repurchase program were suspended indefinitely.

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. All shares repurchased under the various Stock Repurchase Programs were retired upon settlement. At December 31, 2020, the remaining amount that could be used to repurchase shares under the then current Stock Repurchase Program was $200.0 million.

The following table shows the repurchase amounts, shares repurchased, and weighted average price per share for stock repurchases under the various Stock Repurchase Programs for the years indicated:

Dividend Availability and Regulatory Matters

Dividend Availability and Regulatory Matters [Abstract]

Dividend Availability and Regulatory Matters

NOTE 21. 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 DFPI, 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 DFPI 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 DFPI 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. The Bank had a net loss of $256.7 million during the three fiscal years of 2020, 2019, and 2018, compared to dividends of $1.3 billion paid by the Bank during that same period. During 2020, PacWest received $258.0 million in dividends from the Bank. Since the Bank had an accumulated deficit of $2.0 billion at December 31, 2020, for the foreseeable future, dividends from the Bank to PacWest will continue to require DFPI and FDIC approval.

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

Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios of common equity Tier 1, Tier 1, and total capital to risk‑weighted assets ("total capital ratio"), and of Tier I capital to average assets, adjusted for goodwill and other non-qualifying intangible assets and other assets (“leverage ratio”). Common equity Tier 1 capital includes common stockholders’ equity less goodwill and certain other deductions (including a portion of servicing assets and the after‑tax unrealized net gains and losses on securities available‑for‑sale). Tier 1 capital includes common equity Tier 1 plus additional Tier 1 capital instruments meeting certain requirements. Total capital includes Tier 1 capital and other items such as subordinated debt and the allowance for credit losses. All three measures are stated as a percentage of risk‑weighted assets, which are measured based on their perceived credit risk and include certain off‑balance sheet exposures, such as unfunded loan commitments and letters of credit.

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, 2020, such disallowed amounts were $0.2 million for the Company and $16.7 million for the Bank. No assurance can be given that the regulatory capital deferred tax asset limitation will not increase in the future or that the Company or Bank will not have increased deferred tax assets that are disallowed.

Banks considered to be “adequately capitalized” are required to maintain a minimum total capital ratio of 8.0%, a minimum Tier 1 capital ratio of 6.0%, a minimum common equity Tier 1 capital ratio of 4.5%, and a minimum leverage ratio of 4.0%. Banks considered to be “well capitalized” must maintain a minimum total capital ratio of 10.0%, a minimum Tier 1 capital ratio of 8.0%, a minimum common equity Tier 1 capital ratio of 6.5%, and a minimum leverage ratio of 5.0%. As of December 31, 2020, 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, 2020, 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. 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 buffers were 7.0%, 8.5%, and 10.5%. At December 31, 2020, the Company and Bank were in compliance with the capital conservation buffer requirements.

The Company and Bank elected the CECL 5-year regulatory transition guidance for calculating regulatory capital ratios and the December 31, 2020 ratios include this election. This guidance allows an entity to add back to capital 100% of the capital impact from the day one CECL transition adjustment and 25% of subsequent increases to the allowance for credit losses through December 31, 2022. This cumulative amount will then be phased out of regulatory capital over the next three years.

The following tables present actual capital amounts and ratios for the Company and the Bank as of the dates indicated:

We issued or assumed through mergers subordinated debentures to trusts that were established by us or entities that we previously acquired, which, in turn, issued trust preferred securities. The carrying value of subordinated debentures totaled $465.8 million at December 31, 2020. At December 31, 2020, none of the trust preferred securities were included in the Company's Tier I capital under the phase-out limitations of Basel III, and $451.8 million was included in Tier II capital.

Interest payments on subordinated debentures are considered dividend payments under the FRB regulations and subject to the same notification requirements for declaring and paying dividends on common stock.

Accounting Policies [Abstract]

Business Combinations and Other Purchase of Business Transactions

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.

Recently issued Accounting Standards

(a) Accounting Standards Adopted in 2020

Effective January 1, 2020, the Company adopted ASU 2016-13 and the related amendments to ASC Topic 326, “Financial Instruments - Credit Losses,” to replace the incurred loss accounting approach with a current expected credit loss approach for financial instruments measured at amortized cost and other commitments to extend credit. The new standard is generally intended to require earlier recognition of credit losses. While the standard changes the measurement of the allowance for credit losses, it does not change the credit risk of our lending portfolios or the ultimate losses in those portfolios.

Under the CECL approach, the standard requires immediate recognition of estimated credit losses expected to occur over the estimated remaining life of the asset. The forward-looking concept of CECL requires loss estimates to consider historical experience, current conditions and reasonable and supportable forecasts. The standard modifies the other-than-temporary impairment model for available-for-sale debt securities to require entities to record an allowance when recognizing credit losses for available-for-sale securities, rather than reducing the amortized cost of the securities by direct write-offs.

The Company adopted the new standard using the modified retrospective approach and recognized a cumulative effect adjustment to decrease retained earnings by $5.3 million, net of taxes, and increase the allowance for credit losses by $7.3 million without restating prior periods and applied the requirements of the new standard prospectively. There was no cumulative effect adjustment related to available-for-sale securities at adoption. The Company elected to account for accrued interest receivable separately from the amortized cost of loans and leases and investment securities. Accrued interest receivable is included in "Other assets" on the consolidated balance sheets. The Company elected the practical expedient to use the fair value of the collateral at the reporting date when determining the allowance for credit losses for a financial asset for which the repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty based on the entity’s assessment as of the reporting date (collateral dependent financial asset). Additionally, the Company implemented new business processes, new internal controls, and modified existing and/or implemented new internal models and tools to facilitate the ongoing application of the new standard. See Note 4. Loans and Leases for further details.

Effective January 1, 2020, the Company adopted ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" which simplifies 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. The goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount, and an impairment charge would be recognized 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.

The Company used this approach to evaluate its goodwill during the first quarter of 2020, as an unprecedented decline in economic conditions triggered by the Coronavirus Disease ("COVID-19") pandemic caused a significant decline in stock market valuations in March 2020, including our stock price. These events indicated that goodwill may be impaired and resulted in us performing a goodwill impairment assessment. We applied the market approach using an average share price of the Company's stock and a control premium to determine the fair value of the reporting unit. As a result, a goodwill impairment charge of $1.47 billion was recorded in the first quarter of 2020 as the Company's estimated fair value was less than its book value.

Effective January 1, 2020, the Company adopted the provisions of ASU 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework - Changes to Disclosure Requirements for Fair Value Measurements" which add disclosures regarding changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty. Although the guidance modifies our disclosures in 2020, there was no impact to our consolidated financial statements from the adoption of this new standard.

ASU 2020-03, "Codification Improvements to Financial Instruments" ("ASU 2020-03"), revised a wide variety of topics in the Codification with the intent to make the Codification easier to understand and apply by eliminating inconsistencies and providing clarifications. ASU 2020-03 was effective immediately upon its release in March 2020 and did not have a material impact to our consolidated financial statements.

Basis of Presentation

(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.

Use of Estimates

Use of EstimatesThe Company has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period to prepare these consolidated financial statements in conformity with U.S. GAAP. Actual results could differ from those estimates. Material estimates subject to change in the near term include, among other items, the allowance for credit losses (the combination of the allowance for loan and lease losses and the reserve for unfunded loan commitments), the carrying value of goodwill and other intangible assets, and the realization of deferred tax assets. These estimates may be adjusted as more current information becomes available, and any adjustment may be significant.

Cash and Cash Equivalents

Cash and Cash EquivalentsFor purposes of the consolidated statements of cash flows, cash and cash equivalents consist of: (1) cash and due from banks, (2) interest‑earning deposits in financial institutions, and (3) securities purchased under resale agreements. Interest‑earning deposits in financial institutions represent mostly cash held at the FRBSF, the majority of which is immediately available.

Investment Securities

Investment in Debt 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 and 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 value, with unrealized gains or losses reported as a separate component of stockholders’ equity in accumulated other comprehensive income (loss), 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. Such gains or losses are included in "Gain on sale of securities" on the consolidated statements of earnings (loss).

Prior to January 1, 2020, debt securities available-for-sale were measured at fair value and declines in the fair value were reviewed to determine whether the impairment was other-than-temporary. If the decline in fair value was considered temporary, the decline in fair value below the amortized cost basis of a security was recognized in other comprehensive income (loss). If we did not expect to recover the entire amortized cost basis of the security, then an other-than-temporary impairment was considered to have occurred. The cost basis of the security was written down to its estimated fair value and the amount of the write-down was recognized through a charge to earnings. If the amount of the amortized cost basis expected to be recovered increased in a future period, the cost basis of the security was not increased but rather recognized prospectively through interest income.

Effective January 1, 2020, upon the adoption of ASU 2016-13, debt securities available-for-sale are measured at fair value and are subject to impairment testing. A security is impaired if the fair value of the security is less than its amortized cost basis. When an available-for-sale debt security is considered impaired, the Company must determine if the decline in fair value has resulted from a credit-related loss or other factors and then, (1) recognize an allowance for credit losses by a charge to earnings for the credit-related component (if any) of the decline in fair value, and (2) recognize in other comprehensive income (loss) any non-credit related components (if any) of the fair value decline. If the amount of the amortized cost basis expected to be recovered increases in a future period, the valuation allowance would be reduced, but not more than the amount of the current existing allowance for that security.

Loans and Leases

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 primarily 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 to determine if they have experienced a more-than-insignificant deterioration in credit quality since origination or issuance as of the acquisition date and are accounted for as “acquired non‑PCD” or “purchased credit deteriorated” loans.

Acquired non‑PCD loans. Acquired non‑PCD loans are those loans for which there was no evidence of a more-than-insignificant credit deterioration at their acquisition date and it was probable that we would be able to collect all contractually required payments. Acquired non‑PCD loans, together with originated loans, are referred to as Non‑PCD loans. Purchase discounts or premiums on acquired non‑PCD 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 loans with credit deterioration. Prior to January 1, 2020, purchased credit impaired loans were accounted for in accordance with ASC Subtopic 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality.” At the time of acquisition, these loans were recorded at estimated fair value based upon estimated future cash flows with no related allowance for credit losses.

Effective January 1, 2020, upon the adoption of ASU 2016-13, an entity records purchased financial assets with credit deterioration ("PCD assets") at the purchase price plus the allowance for credit losses expected at the time of acquisition. This allowance is recognized through a gross-up that increases the amortized cost basis of the asset with no effect on net income. Subsequent changes (favorable and unfavorable) in expected cash flows are recognized immediately in net income by adjusting the related allowance.

Leases to customers. We provide equipment financing to our customers primarily with direct financing and operating leases. 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 accounting for allowance for loans and leases.

We provide equipment financing through operating leases where we facilitate the purchase of equipment leased to customers. The equipment is shown on our consolidated balance sheets as "Equipment leased to others under operating leases" and is depreciated to its estimated residual value at the end of the lease term, shown as "Leased equipment depreciation" in the consolidated statements of earnings (loss), according to our fixed asset accounting policy. We receive periodic rental income payments under the leases, which are recorded as "Noninterest income" in the consolidated statements of earnings (loss).

Delinquent or past due loans and leases. Loans and leases are considered delinquent when principal or interest payments are past due 30 days or more. Delinquent loans may remain on accrual status between 30 days and 89 days past due.

Nonaccrual loans and leases. When we discontinue the accrual of interest on a loan or lease it is designated as nonaccrual. We discontinue the accrual of interest on a loan 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.

Individually Evaluated Loans and Leases. Loans and leases that do not share similar risk characteristics with other financial assets are individually evaluated for impairment and excluded from loan pools used within the collective evaluation of estimated credit losses. We defined the following criteria for what constitutes a “default”, which results in a loan no longer sharing similar risk characteristics with other loans, and therefore requires an individual evaluation for expected credit losses. The criteria for default may include any one of the following:

•On nonaccrual status,

•Modified under a TDR,

•Payment delinquency of 90 days or more,

•Partial charge-off recognized,

•Risk rated doubtful or loss, or

•Reasonably expected to be modified under a TDR.

Defaulted loans and leases with outstanding balances over $250,000 are reviewed individually for expected credit loss. Individually evaluated loans are measured at the present value of the expected future cash flows discounted at the loan's initial effective interest rate, unless the loans are collateral dependent, in which case loan impairment is based on the estimated fair value of the underlying collateral. A loan is considered collateral-dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the 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. An individually evaluated reserve and/or charge off would be recognized when the present value of expected future cash flows or the fair value of the underlying collateral is below the amortized cost of the loan. If the measured amount of any individually reviewed loan exceeds its amortized cost, further review is required to determine whether a positive allowance should be added (but only up to amounts previously written off) to its amortized cost basis in order to reflect the net amount expected to be collected.

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.

The Company has granted various commercial and consumer loan modifications to provide borrowers relief from the economic impacts of COVID-19. In accordance with the Coronavirus Aid, Relief, and Economic Security ("CARES") Act, the Company elected to not apply TDR classification to COVID-19 related loan modifications that met all of the requisite criteria as stipulated in the CARES Act.

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. Loan modifications that qualify as troubled debt restructurings are individually evaluated for expected credit losses 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.

Impaired loans and leases. Prior to January 1, 2020, a loan or lease was considered impaired when it was probable that we would be unable to collect all amounts due according to the contractual terms of the loan or lease agreement. Impaired loans and leases included loans and leases on nonaccrual status and performing troubled debt restructured loans. Income from impaired loans was recognized on an accrual basis unless the loan was on nonaccrual status. Income from loans on nonaccrual status was recognized to the extent cash was received and when the loan’s principal balance was deemed collectable. We measured 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 was 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 was not collateral‑dependent. The impairment amount on a collateral‑dependent loan or lease was charged‑off, and the impairment amount on a loan that was not collateral‑dependent was generally recorded as a specific reserve within our allowance for loan and lease losses.

Allowance for Credit Losses

Allowance for Credit Losses on Loans and Leases Held for Investment

Effective January 1, 2020, upon the adoption of ASU 2016-13, the Company replaced the incurred loss accounting approach with the current expected credit loss ("CECL") approach for financial instruments measured at amortized cost and other commitments to extend credit. CECL requires the immediate recognition of estimated credit losses expected to occur over the estimated remaining life of the asset. The forward-looking concept of CECL requires loss estimates to consider historical experience, current conditions and reasonable and supportable forecasts.

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 the amortized cost basis of loans and leases, while the reserve for unfunded loan commitments is included within "Accrued interest payable and other liabilities" on the consolidated balance sheets. The amortized cost basis of loans and leases does not include accrued interest receivable, which is included in "Other assets" on the consolidated balance sheets. The "Provision for credit losses" on the consolidated statements of earnings (loss) is a combination of the provision for loan and lease losses and the provision for unfunded loan commitments.

Under the CECL methodology, expected credit losses reflect losses over the remaining contractual life of an asset, considering the effect of prepayments and available information about the collectability of cash flows, including information about relevant historical experience, current conditions, and reasonable and supportable forecasts of future events and circumstances. Thus, the CECL methodology incorporates a broad range of information in developing credit loss estimates. The resulting allowance for loan and lease losses is deducted from the associated amortized cost basis to reflect the net amount expected to be collected. Subsequent changes in this estimate are recorded through the provision for credit losses and the allowance. The CECL methodology could result in significant changes to both the timing and amounts of provision for credit losses and the allowance as compared to historical periods. Loans and leases that are deemed to be uncollectable are charged off and deducted from the allowance. The provision for credit losses and recoveries on loans and leases previously charged off are added to the allowance.

The allowance for loan and lease losses is comprised of an individually evaluated component for loans and leases that no longer share similar risk characteristics with other loans and leases and a pooled loans component for loans and leases that share similar risk characteristics.

A loan or lease with an outstanding balance greater than $250,000 is individually evaluated for expected credit loss when it is probable that we will be unable to collect all amounts due according to the original contractual terms of the agreement. We select loans and leases for individual assessment on an ongoing basis using certain criteria such as payment performance, borrower reported and forecasted financial results, and other external factors when appropriate. We measure the current expected credit loss of an individually evaluated 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 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.

Our CECL methodology for the pooled loans component includes both quantitative and qualitative loss factors which are applied to our population of loans and leases and assessed at a pool level. The quantitative CECL model estimates credit losses by applying pool-specific probability of default ("PD") and loss given default ("LGD") rates to the expected exposure at default ("EAD") over the contractual life of loans and leases. The qualitative component considers internal and external risk factors that may not be adequately assessed in the quantitative model.

The loan portfolio is segmented into four loan segments, eight loan classes, and 19 loan pools (excluding Paycheck Protection Program loans, which are fully government guaranteed) based upon loan type that share similar default risk characteristics to calculate quantitative loss factors for each pool. Three of these loan pools have insignificant current balances and/or insignificant historical losses, thus, estimated losses are calculated using historical loss rates from the first quarter of 2009 to the current period rather than econometric regression modeling. For the remaining 16 loan pools, we estimate the PD during the reasonable and supportable forecast period using seven econometric regression models developed to correlate macroeconomic variables to historical credit performance (based on quarterly transition matrices from 2009 to 2019, which include risk rating upgrades/downgrades and defaults).

The loans and unfunded commitments are grouped into nine LGD pools based on portfolio classes that share similar collateral risk characteristics. LGD rates are computed based on the net charge-offs recognized divided by the EAD of defaulted loans starting with the first quarter of 2009 to the current period. The PD and LGD rates are applied to the EAD at the loan or lease level based on contractual scheduled payments and estimated prepayments. We use our actual historical loan prepayment experience from 2009 to 2019 to estimate future prepayments by loan pool. Loans and leases with outstanding balances less than or equal to $250,000, where it is probable that we will be unable to collect all amounts due according to the contractual terms of the agreement, remain in their respective pools and are assigned a 100% probability of default.

For the reasonable and supportable forecast period, future macroeconomic events and circumstances are estimated over a 4-quarter time horizon using a single scenario economic forecast that is consistent with management's current expectations for the 16 loan pools. We use economic forecasts from Moody's Analytics in this process. The economic forecast is updated monthly; therefore, the one used for each quarter-end calculation is generally released a few weeks prior to quarter-end. If economic conditions as of the balance sheet date change materially, management would consider a qualitative adjustment. The key macroeconomic assumptions used in each of the seven PD regression models include two or three of the following economic indicators: Real GDP, unemployment rates, CRE Price Index, the BBB corporate spread, nominal disposable income, and CPI.

The quantitative CECL model applies the projected rates based on the economic forecasts for the 4-quarter reasonable and supportable forecast horizon to EAD to estimate defaulted loans. During this forecast horizon, prepayment rates during a historical period that exhibits economic conditions most similar to the economic forecast are used to estimate EAD. If no historical period from 2009 to 2019 exhibits economic conditions that are similar to the economic forecast, management uses its best estimate of prepayments expected over the reasonable and supportable forecast period which may, in some circumstances, be the average of all historical prepayment experience. Historical LGD rates are applied to estimated defaulted loans to determine estimated credit losses. We then use a 2-quarter reversion period to revert on a straight-line basis from the PD, LGD, and prepayment rates used during the reasonable and supportable forecast period to the Company’s historical PD, LGD, and prepayment experience. Subsequent to the reversion period for the remaining contractual life of loans and leases, the PD, LGD, and prepayment rates are based on historical experience from 2009 to 2019. PD regression models and prepayment rates are updated on an annual basis. LGD rates are updated every quarter to reflect current charge-off activity.

The PDs calculated by the quantitative models are highly correlated to our internal risk ratings assigned to each loan and lease. 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 and leases on a regular basis. The credit risk ratings assigned to every loan and lease are as follows:

•High Pass: (Risk ratings 1-2) Loans and leases rated as "high pass" exhibit a favorable credit profile and have minimal risk characteristics. Repayment in full is expected, even in adverse economic conditions.

•Pass: (Risk ratings 3-4) Loans and leases rated as "pass" are not adversely classified and collection and repayment in full are expected.

•Special Mention: (Risk rating 5) 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.

•Substandard: (Risk rating 6) 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.

•Doubtful: (Risk rating 7) 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.

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 4. Loans and Leases.

In addition to our internal risk rating process, our federal and state banking regulators, as an integral part of their examination process, periodically review the Company’s loan and lease risk rating classifications. Our regulators may require the Company to recognize rating downgrades based on 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.

The qualitative portion of the reserve on pooled loans and leases represents management’s judgment of additional considerations to account for internal and external risk factors that are not adequately measured in the quantitative reserve. The qualitative loss factors consider idiosyncratic risk factors, conditions that may not be reflected in quantitatively derived results, or other relevant factors to ensure the allowance for credit losses reflects our best estimate of current expected credit losses. Current and forecasted economic trends and underlying market values for collateral dependent loans are generally considered to be encompassed within the CECL quantitative reserve. An incremental qualitative adjustment may be considered when economic forecasts exhibit higher levels of volatility or uncertainty.

In addition to economic conditions and collateral dependency, the other qualitative criteria we consider when establishing the loss factors include the following:

•Legal and Regulatory - matters that could impact our borrowers’ ability to repay our loans and leases;

•Concentrations - loan and lease portfolio composition and any loan concentrations;

•Lending Policy - current lending policies and the effects of any new policies or policy amendments;

•Nature and Volume - loan and lease production volume and mix;

•Problem Loan Trends - loan and lease portfolio credit performance trends, including a borrower's financial condition, credit rating, and ability to meet loan payment requirements;

•Loan Review - results of independent credit review; and

•Management - changes in management related to credit administration functions.

We estimate the reserve for unfunded loan commitments using the same PD, LGD, and prepayment rates for the quantitative credit losses and qualitative loss factors as used for the allowance for loan and lease losses. The EAD for the reserve for unfunded loan commitments is computed using expected future utilization rates of the unfunded commitments during the contractual life of the commitments based on historical usage by loan pool from 2015 to 2019. The utilization rates are updated on an annual basis.

The CECL methodology requires a significant amount of management judgment in determining the appropriate allowance for credit losses. Most of the steps in the methodology involve judgment and are subjective in nature including, among other things: segmenting the loan and lease portfolio; determining the amount of loss history to consider; selecting predictive econometric regression models that use appropriate macroeconomic variables; determining the methodology to forecast prepayments; selecting the most appropriate economic forecast scenario; determining the length of the reasonable and supportable forecast and reversion periods; estimating expected utilization rates on unfunded loan commitments; and assessing relevant and appropriate qualitative factors. In addition, the CECL methodology is dependent on economic forecasts which are inherently imprecise and will change from period to period. Although the allowance for credit losses is considered appropriate, there can be no assurance that it will be sufficient to absorb future losses.

Management believes the allowance for credit losses is appropriate for the current expected credit losses in our loan and lease portfolio and associated unfunded commitments, and the credit risk ratings and inherent loss rates currently assigned are reasonable and appropriate as of the reporting date. 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 consolidated financial statements.

Prior to January 1, 2020, the allowance for loan losses was measured using the incurred loss accounting approach. The allowance for credit losses was 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 was 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.

The allowance for loan and lease losses had a general reserve component for unimpaired loans and leases and a specific reserve component for impaired loans and leases.

A loan or lease was considered impaired when it was probable that we would be unable to collect all amounts due according to the original contractual terms of the agreement. We assessed 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 measured impairment of a loan or lease based upon the fair value of the underlying collateral if the loan or lease was collateral-dependent or the present value of cash flows, discounted at the effective interest rate, if the loan or lease was not collateral-dependent. To the extent a loan or lease balance exceeded the estimated collectable value, a specific reserve or charge-off was recorded depending upon either the certainty of the estimate of loss or the fair value of the loan’s collateral if the loan was collateral-dependent. Impaired loans and leases with outstanding balances less than or equal to $250,000 might not be individually assessed for impairment but would be 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 included both quantitative and qualitative loss factors which were applied to our population of unimpaired loans and leases to estimate our general reserves. The quantitative loss factors determination was based on a probability of default/loss given default ("PD/LGD") methodology which considered 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 had higher quantitative loss factors. The qualitative loss factors considered, among other things, current economic trends and forecasts, current collateral values and performance trends, credit performance trends, and the loan portfolio's current composition.

The quantitative estimation of the allowance for credit losses considered actual historical loan and lease charge-off experience over a 44-quarter look-back period starting with the first quarter of 2009. This look-back period was inclusive of the average timeframe over which charge-offs typically occurred following loan or lease origination and allowed for the capture of sufficient loss observations that were relevant to the current portfolio. When estimating the general reserve component for the various pools of similar loan types, the loss factors applied to the loan pools considered the current credit risk ratings, giving greater weight to loans with more adverse credit risk ratings. We recognized that the determination of the allowance for credit losses was sensitive to the assigned credit risk ratings and inherent loss rates at any given point in time.

Land, Premises and Equipment

Land, Premises and EquipmentPremises 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 (loss) 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.

Foreclosed Assets

Foreclosed AssetsForeclosed 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 (loss) 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."

Income Taxes

Income TaxesIncome 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 of the same jurisdiction, net of valuation allowances, are grouped together and reported net on the consolidated balance sheets.On a periodic 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.

Goodwill and Intangible Assets

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 annually unless a triggering event occurs thereby requiring an updated assessment. Our regular annual impairment assessment occurs in the fourth quarter. Goodwill represents the excess of the purchase price over the fair value of the net assets and other identifiable intangible assets acquired. Impairment exists when the carrying value of the goodwill exceeds its 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 (loss).

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 amount would be recognized as a charge to "Noninterest expense" in the consolidated statements of earnings (loss).

Stock-based Compensation

Stock-Based CompensationThe 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 and the employee continues to meet the service requirement of the award.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.

Earnings Per Share

Earnings (Loss) Per ShareIn 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 (loss) 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 (loss) to determine that amount of earnings (loss) available to common stockholders. In the two‑class method, the amount of our earnings (loss) available to common stockholders is divided by the weighted average shares outstanding, excluding any unvested restricted stock, for both the basic and diluted earnings (loss) per share.

Business Combinations

Business CombinationsBusiness 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 consolidated statements of earnings (loss) from the date of acquisition. Acquisition‑related costs, including conversion and restructuring charges, are expensed as incurred.

Business Segments

(t) 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, 2020 and since December 31, 2015, we operated as one reportable segment. The factors considered in making this determination include the nature of products and offered services, geographic regions in which we operate, the applicable regulatory environment, and the discrete financial information reviewed by our key decision makers. Through our network of banking offices nationwide, our entire operations provide relationship-based banking products, services and solutions for small to mid-sized companies, entrepreneurial and venture-backed 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.

TDRs are a result of rate reductions, term extensions, fee concessions, transfers to foreclosed assets, discounted loan payoffs, and debt forgiveness, or a combination thereof. The Company has granted various commercial and consumer loan modifications to provide borrowers relief from the economic impacts of COVID-19. In accordance with the CARES Act, the Company elected to not apply TDR classification to COVID-19 related loan modifications that met all of the requisite criteria as stipulated in the CARES Act.

(1)     The population of defaulted TDRs for the period indicated includes only those loans restructured during the preceding 12-month period. For example, for the year ended December 31, 2020, the population of defaulted TDRs includes only those loans restructured after December 31, 2019. The table excludes defaulted TDRs in those classes for which the recorded investment was zero at the end of the period.

(2)     One commercial asset-based loan with a pre-modification balance of $27.3 million and a post-modification balance of $32.3 million was previously restructured in December 2017.

At December 31, 2020 and 2019, we had unfunded commitments related to TDRs of $0.9 million and $1.2 million.

Leases Receivable

We provide equipment financing to our customers primarily with operating and direct financing leases. For direct financing leases, lease receivables are recorded on the balance sheet but the leased equipment is not, although we generally retain legal title to the leased equipment 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. Direct financing leases are subject to our accounting for allowance for loan and lease losses. See Note 9. Leases for information regarding operating leases where we are the lessor.

The following table provides the components of leases receivable income for the period indicated:

The higher provision for loan and lease losses in 2020 was primarily a result of the impact of the current economic forecast used in our ACL estimation, which reflected a significant deterioration in key macro-economic forecast variables such as unemployment and Real GDP as a result of the COVID-19 pandemic, significant loan downgrades into special mention, and higher provisions on individually evaluated loans.

We actively participated in the Paycheck Protection Program ("PPP"), under the provisions of the CARES Act during the second quarter of 2020. As of December 31, 2020, PPP loans had an outstanding balance of approximately $1.1 billion. The loans have two or three year terms, are fully guaranteed by the SBA, and do not carry an allowance.

A loan is considered collateral-dependent, and is individually evaluated for reserve purposes, when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. The following table summarizes collateral-dependent loans held for investment by collateral type as of the following date:

Allowance for Credit Losses

The allowance for credit losses is the combination of the allowance for loan and lease losses and the reserve for unfunded loan commitments. The reserve for unfunded loan commitments is included within "Accrued interest payable and other liabilities" on the consolidated balance sheets.

The allowance for loan and lease losses increased by $209.4 million in 2020 due primarily to a provision for loan and lease losses of $293.0 million. The higher provision for loan and lease losses in 2020 was primarily a result of the impact of the current economic forecast used in our ACL estimation, which reflected a significant deterioration in key macro-economic forecast variables such as unemployment and Real GDP as a result of the COVID-19 pandemic, significant loan downgrades into special mention, and higher provisions on individually evaluated loans.

We actively participated in the Paycheck Protection Program ("PPP"), under the provisions of the CARES Act during the second quarter of 2020. As of December 31, 2020, PPP loans had an outstanding balance of approximately $1.1 billion. The loans have two or three year terms, are fully guaranteed by the SBA, and do not carry an allowance.

A loan is considered collateral-dependent, and is individually evaluated for reserve purposes, when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral.

The amount of interest income that would have been recorded on nonaccrual loans and leases at December 31, 2020 and 2019 had such loans and leases been current in accordance with their original terms was $7.5 million and $8.1 million for 2020 and 2019.

At December 31, 2020, nonaccrual loans and leases included $36.5 million of loans and leases 90 or more days past due, $3.4 million of loans 30 to 89 days past due and $51.3 million of current loans that were placed on nonaccrual status based on management’s judgment regarding their collectability. At December 31, 2019, nonaccrual loans and leases included $11.1 million of loans and leases 90 or more days past due, $1.2 million of loans 30 to 89 days past due and $80.0 million of current loans that were placed on nonaccrual status based on management’s judgment regarding their collectability.

TDRs are a result of rate reductions, term extensions, fee concessions, transfers to foreclosed assets, discounted loan payoffs, and debt forgiveness, or a combination thereof. The Company has granted various commercial and consumer loan modifications to provide borrowers relief from the economic impacts of COVID-19. In accordance with the CARES Act, the Company elected to not apply TDR classification to COVID-19 related loan modifications that met all of the requisite criteria as stipulated in the CARES Act.

(1)     The population of defaulted TDRs for the period indicated includes only those loans restructured during the preceding 12-month period. For example, for the year ended December 31, 2020, the population of defaulted TDRs includes only those loans restructured after December 31, 2019. The table excludes defaulted TDRs in those classes for which the recorded investment was zero at the end of the period.

(2)     One commercial asset-based loan with a pre-modification balance of $27.3 million and a post-modification balance of $32.3 million was previously restructured in December 2017.

At December 31, 2020 and 2019, we had unfunded commitments related to TDRs of $0.9 million and $1.2 million.

Leases Receivable

We provide equipment financing to our customers primarily with operating and direct financing leases. For direct financing leases, lease receivables are recorded on the balance sheet but the leased equipment is not, although we generally retain legal title to the leased equipment 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. Direct financing leases are subject to our accounting for allowance for loan and lease losses. See Note 9. Leases for information regarding operating leases where we are the lessor.

The following table provides the components of leases receivable income for the period indicated:

The higher provision for loan and lease losses in 2020 was primarily a result of the impact of the current economic forecast used in our ACL estimation, which reflected a significant deterioration in key macro-economic forecast variables such as unemployment and Real GDP as a result of the COVID-19 pandemic, significant loan downgrades into special mention, and higher provisions on individually evaluated loans.

We actively participated in the Paycheck Protection Program ("PPP"), under the provisions of the CARES Act during the second quarter of 2020. As of December 31, 2020, PPP loans had an outstanding balance of approximately $1.1 billion. The loans have two or three year terms, are fully guaranteed by the SBA, and do not carry an allowance.

A loan is considered collateral-dependent, and is individually evaluated for reserve purposes, when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. The following table summarizes collateral-dependent loans held for investment by collateral type as of the following date:

Allowance for Credit Losses

The allowance for credit losses is the combination of the allowance for loan and lease losses and the reserve for unfunded loan commitments. The reserve for unfunded loan commitments is included within "Accrued interest payable and other liabilities" on the consolidated balance sheets.
