NOTE 1.  ORGANIZATION    

PacWest Bancorp, a Delaware corporation, is a bank holding company registered under the BHCA and headquartered in Los Angeles, California, with an executive office in Denver, Colorado. 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 a relationship-based community bank focused on providing business banking and treasury management services to small, middle-market, and venture-backed businesses. The Bank offers a broad range of loan and lease and deposit products and services through full-service branches throughout California and in Durham, North Carolina and Denver, Colorado, and loan production offices around the country.

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 interest paid by the Bank on deposits and borrowings, compensation, occupancy, and general operating expenses.

Significant Accounting Policies

Our accounting policies are described in Note 1. Nature of Operations and Summary of Significant Accounting Policies, of our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2022 as filed with the Securities and Exchange Commission ("Form 10-K"). Updates to our significant accounting policies described below reflect the impact of the adoption of ASU 2022-02, "Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures ("ASU 2022-02")," specifically the amendment to troubled debt restructurings, and organizational changes which resulted in changes to our reportable operating segments.

Loan Modifications to Borrowers Experiencing Financial Difficulty

Loan modifications made to borrowers experiencing financial difficulty constitute modifications of receivables in the form of principal forgiveness, an interest rate reduction, an other than-insignificant payment delay, or a term extension. ASU 2022-02 eliminated the concept of troubled debt restructurings and introduced broader modification reporting requirements. Previously, troubled debt restructurings included any type of modification that included a below market concession which was granted both to a borrower in financial difficulty and as a result of financial difficulty. Loan modifications made to borrowers experiencing financial difficulty no longer consider whether a market concession has been granted, as was required with troubled debt restructurings, but rather includes as modifications within the four listed reportable modification types to a borrower deemed to be experiencing financial difficulty. An assessment of whether a borrower is experiencing financial difficulty is made on the date of the modification. Loans reported in this classification have a rating of substandard or worse, and may include both accruing and nonaccruing loans. Loans are assessed to determine whether the modification constitutes a new loan or a continuation of the existing loan. Depending on the terms of the modification and nature of the borrower, this may result in a downgrade or placing a loan on nonaccrual status, which in turn would impact the loan's classification within the ALLL. Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses because of the measurement methodologies used to estimate the allowance, a change to the allowance for credit losses is generally not recorded upon modification.

Business Segments

We regularly assess our strategic plans, operations, reporting structures and financial information provided to management to identify our reportable segments. Civic, a lending subsidiary we acquired in February 2021, has historically been identified as an operating segment. In the fourth quarter of 2022, Civic met a quantitative threshold which required it to be disclosed as a reportable operating segment. Therefore, we had two reportable operating segments as of December 31, 2022: Commercial Banking and Civic, and a third segment, Other, which was used for inter-segment eliminations. In the first quarter of 2023, we began a restructuring of Civic which included removing most of Civic's top management and transferring day-to-day management of most of Civic's operating functions to managers at the Bank. Due to the restructuring of Civic, discrete financial information is no longer prepared. Our management reporting captures the direct expenses of Civic, however, none of the expenses now being incurred to manage Civic are being directly charged or allocated to Civic. Therefore, it is no longer feasible to produce meaningful, separate full financial statements, and thus, discrete financial information for Civic is no longer prepared or distributed to our chief operating decision maker. Thus, Civic no longer meets the criteria to be considered a reportable operating segment as of March 31, 2023. We sold the Civic business in the second quarter of 2023, and we are retaining and servicing the Civic loans on our balance sheet. At September 30, 2023, June 30, 2023, and March 31, 2023, we operated as one reportable segment - Commercial Banking.

Accounting Standards Adopted in 2023

Effective January 1, 2023, we completed the adoption of ASU 2022-02, “Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures," by eliminating the accounting guidance for TDRs by creditors, in ASC 310-40, "Receivables – Troubled Debt Restructurings by Creditors," while enhancing disclosure requirements for restructurings involving borrowers that are experiencing financial difficulty. The Company updated its disclosures in Note 4. Loans and Leases to present information regarding loan modifications to borrowers experiencing financial difficulty. There was no transition adjustment recorded to retained earnings upon adoption. The adoption of this amendment did not have a material impact on the Company’s condensed consolidated financial statements.

Basis of Presentation    

Our interim condensed consolidated financial statements are prepared in accordance with U.S. GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, certain disclosures accompanying annual consolidated financial statements are omitted. In the opinion of management, all 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 for the interim periods, have been included. The current period's results of operations are not necessarily indicative of the results that ultimately may be achieved for the year. The interim condensed consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Form 10-K.

Use of Estimates

We have made a number of estimates and assumptions related to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period to prepare these condensed consolidated financial statements in conformity with U.S. GAAP. 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 intangible assets, the fair value of loans held for sale, and the realization of deferred tax assets. These estimates may be adjusted as more current information becomes available, and any adjustment may be significant.

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 certain of our loan portfolio classes and subclasses to better reflect and report our lending. We made the following changes: (1) moved the "Multi-family" loan subclass from the residential real estate mortgage class into its own loan class; (2) moved the "Construction - renovation" loan subclass from the residential real estate construction and land loan class to the residential real estate mortgage class and renamed it "Residential renovation;" and (3) renamed the residential real estate mortgage loan class as "Other residential." All of the loan and allowance tables, both current period and prior periods, reflect these changes and realignment.

Risks and Uncertainties

The bank failures earlier in 2023 involving three prominent regional banks resulted in significant market volatility among publicly traded bank holding companies, and, in particular, regional banks like PacWest. These bank failures, and the resulting customer fear of additional bank failures, increased the following risks and uncertainties regarding our business: (i) the loss of customer deposits which, in turn, put pressure on our liquidity position, (ii) the decrease in our net interest margin resulting from replacing lower-cost customer deposits with higher-cost brokered deposits and borrowings, (iii) the downgrading of our credit rating by third-party rating agencies which may result in increased borrowing costs and/or trigger additional collateral or funding requirements, and (iv) the increase in operating costs due to higher FDIC assessments and other costs necessary to respond to increased regulatory requirements.

To respond to these increased risks and uncertainties, we have taken the following actions to mitigate these risks: (a) we pledged additional assets as collateral for borrowings to increase our liquidity position for potential deposit outflows, (b) we increased the number of customers enrolled in reciprocal deposit programs that increases the amount of FDIC insurance coverage on their account(s) to help retain these customers, (c) we are offering competitive promotional rates on our deposit products to attract new customer deposits, (d) we completed strategic asset sales in the second quarter of 2023 to improve our liquidity position and capital ratios, and (e) in the second quarter of 2023, we reduced our common dividend from $0.25 to $0.01 to improve our liquidity position and capital ratios.

At the end of the second quarter, with the sale of non-core loan portfolios completed, we believed that we had addressed the liquidity risk present at the end of the first quarter and had improved our capital ratios. Our net interest margin and overall profitability were reduced in the third quarter from the effect of the loan sales and continued to be affected by elevated levels of higher-cost brokered deposits and borrowings. Our current priorities are to continue to increase customer deposits to replace brokered deposits and borrowings and to reduce operating expenses. If we are not successful, our level of earnings will be lower than historical periods.

On July 25, 2023, PacWest announced the signing of a definitive agreement and plan of merger (the "merger agreement") whereby PacWest will merge with Banc of California, Inc. ("Banc" and following the merger, the "combined company") (the "merger"). Upon the terms and subject to the conditions set forth in the merger agreement, at closing each share of common stock of PacWest issued and outstanding immediately prior to the closing (subject to certain exceptions) will be converted into the right to receive 0.6569 of a share of common stock of Banc. In addition, in connection with the closing, each share of Series A preferred stock will be converted into the right to receive one share of a newly created series of preferred stock of Banc having such powers, preferences and rights, and such qualifications, limitations and restrictions, taken as a whole, that are not materially less favorable to the holders of the Series A preferred stock. Concurrently with its entry into the merger agreement, Banc entered into separate investment agreements with affiliates of funds managed by Warburg Pincus LLC (the "Warburg Investors") and certain investment vehicles sponsored, managed or advised by Centerbridge Partners, L.P. (the "Centerbridge Investor" and collectively with the Warburg Investors, the "Investors") to invest, substantially concurrently with the merger closing, in an aggregate of $400 million of shares of Banc common stock and Banc non-voting, common-equivalent stock, and Banc will issue to the Investors warrants to purchase approximately 18.9 million shares of Banc non-voting, common-equivalent stock or shares of Banc common stock (collectively, the "equity investments").

Banc, headquartered in Santa Ana, California, is the parent of Banc of California, N.A., with $9.25 billion in assets with 32 offices including 26 full-service branches located throughout Southern California at September 30, 2023. In connection with the merger, Banc of California, N.A. will merge with and into Pacific Western Bank, which will take the Banc of California name and become a Federal Reserve member.

The merger, which was approved by the PacWest and Banc boards of directors, and with respect to which all regulatory approvals have been received as of October 19, 2023, is expected to close on or about November 30, 2023. The transaction remains subject to certain closing conditions, including the closing of the equity investments described above occurring substantially concurrently with the merger closing and requisite approval by the stockholders of each company.

NOTE 2. RESTRICTED CASH

The FRBSF establishes cash reserve requirements that its member banks must maintain based on a percentage of deposit liabilities. There were no reserves required to be held at the FRBSF for the nine months ended September 30, 2023. As of September 30, 2023 and December 31, 2022, we pledged cash collateral for our derivative contracts of $3.3 million and $2.7 million. We have cash which is restricted based on the terms of some of our borrowing agreements that totaled $145.6 million at September 30, 2023 and $131.5 million at December 31, 2022. Starting in the second quarter of 2023, we began to pledge cash to secure the standby letters of credit that we have issued on behalf of our customers. At September 30, 2023, the balance of such restricted cash totaled $56.0 million.

As of September 30, 2023, the Company had not recorded an allowance for credit losses on securities available-for-sale. The Company does not consider unrealized losses on such securities to be attributable to credit-related factors, as the unrealized losses have occurred as a result of changes in non-credit related factors such as interest rates, market spreads, and market conditions subsequent to purchase.

As of September 30, 2023, securities available-for-sale with a fair value of $4.2 billion were pledged as collateral primarily for the Bank Term Funding Program borrowings, the FRB secured line of credit, and letters of credit.

The securities that were in an unrealized loss position at September 30, 2023, were considered impaired and required further review to determine if the unrealized losses were credit-related. We concluded the 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 "Accumulated other comprehensive (loss) income" of "Stockholders' equity" on the condensed consolidated balance sheets. Although we periodically sell securities for portfolio management purposes, we do not foresee having to sell any impaired securities 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.

CMBS, CMOs, and MBS 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.

Credit losses on HTM securities are recorded at the time of purchase, acquisition, or when the Company designates securities as held-to-maturity. Credit losses on HTM securities are representative of current expected credit losses that may be incurred over the life of the investment. Accrued interest receivable on HTM securities, which is included in other assets on the condensed consolidated balance sheets, is excluded from the estimate of expected credit losses. HTM U.S. treasury securities and agency-backed MBS securities are considered to have no risk of loss as they are either explicitly or implicitly guaranteed by the U.S. government. The change in fair value in the HTM private label CMBS portfolio is solely driven by changes in interest rates. The Company has no knowledge of any underlying credit issues and the cash flows underlying the debt securities have not changed and are not expected to be impacted by changes in interest rates and, thus, there is no related ACL for this portfolio. The underlying bonds in the Company’s HTM municipal securities and HTM corporate debt securities portfolios are evaluated for credit losses in conjunction with management’s estimate of the allowance for credit losses based primarily on credit ratings.

Commercial MBS 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.

NOTE 4.  LOANS AND LEASES

Our loans are carried at the principal amount outstanding, net of deferred fees and costs, and in the case of acquired and purchased loans, net of purchase discounts and premiums. Deferred fees and costs and purchase discounts and premiums on acquired loans are recognized as an adjustment to interest income over the contractual life of the loans primarily using the effective interest method or taken into income when the related loans are paid off or included in the carrying amount of loans that are sold.

It is our policy to discontinue accruing interest when principal or interest payments are past due 90 days or more (unless the loan is both well secured and in the process of collection) or when, in the opinion of management, there is a reasonable doubt as to the collectability of a loan or lease in the normal course of business. Interest income on nonaccrual loans is recognized only to the extent cash is received and the principal balance of the loan is deemed collectable.

On January 1, 2023, the Company adopted ASU 2022-02, "Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures" ("ASU 2022-02"), which eliminated the accounting guidance for troubled debt restructurings while enhancing disclosure requirements for certain loan refinancing and restructurings by creditors when a borrower is experiencing financial difficulty. This guidance was applied on a prospective basis. The following table presents our loan modifications made to borrowers experiencing financial difficulty by type of modification for the period indicated with related amortized cost balances as of the date indicated:

At September 30, 2023, there were other residential real estate loans for $8.7 million and other commercial loans for $4,000 that had been modified in the form of a term extension during the preceding three-month period and subsequently defaulted during the three months ended September 30, 2023. There were other residential real estate loans for $9.1 million and other commercial loans for $4,000 that had been modified in the form of a term extension during the preceding nine-month period and subsequently defaulted during the nine months ended September 30, 2023.

Prior to the adoption of ASU 2022-02, the Company accounted for a modification to the contractual terms of a loan that resulted in granting a concession to a borrower experiencing financial difficulties as a TDR. TDRs were a result of rate reductions, term extensions, fee concessions, transfers to foreclosed assets, discounted loan payoffs, and debt forgiveness, or a combination thereof. The following table presents our troubled debt restructurings of loans held for investment by loan portfolio segment and class for the periods indicated:

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 8. Leases for information regarding operating leases where we are the lessor.

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

The allowance for loan and lease losses increased by $3.1 million in the third quarter of 2023 to $222.3 million due primarily to an increase in qualitative reserves for loans secured by office properties, offset partially by net charge-offs and lower reserves needed for lower loan balances. For additional information regarding the calculation of the allowance for loan and lease losses using the CECL methodology, including discussion of forecasts used to estimate the allowance, please see Note 1(j).

NOTE 6.  GOODWILL AND OTHER INTANGIBLE ASSETS, NET

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 at the reporting unit level 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 the fair value of the reporting unit. An impairment loss would be recognized in an amount equal to that excess as a charge to "Noninterest expense" in the condensed consolidated statements of earnings.

The impact to banks triggered by the closure of two well-known regional banks caused a significant decline in bank stock prices in March 2023, 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 2023. We applied the market approach using an average share price of the Company's stock and a control premium to determine the estimated fair value of the reporting unit. The control premium was based upon management's judgment using historical information of control premiums for completed bank acquisitions. As a result, we recorded a goodwill impairment charge of our entire goodwill balance of $1.4 billion in the first quarter of 2023 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.

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

	Goodwill

(1)    Balance is net of unamortized issuance costs of $10.9 million and $4.8 million of accrued exit fees. Rate calculation does not include the effects of issuance costs and exit fees.

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 financing capacity with the FHLB as of September 30, 2023 of $4.3 billion, collateralized by a blanket lien on $8.5 billion of qualifying loans and $18.4 million of securities. As of September 30, 2023, there were no balances outstanding. As of December 31, 2022, the balance outstanding was $1.3 billion, which consisted of an overnight advance and two term advances with maturity dates of January 2023 and February 2023.

FRBSF Secured Line of Credit. The Bank has a secured line of credit with the FRBSF. As of September 30, 2023, the Bank had secured borrowing capacity of $6.5 billion collateralized by liens covering $6.8 billion of qualifying loans and $1.5 billion of securities. As of September 30, 2023 and December 31, 2022, there were no balances outstanding.

FRBSF Bank Term Funding Program. In March of 2023, the Bank participated in the FRBSF Bank Term Funding Program. As of September 30, 2023, the Bank had secured borrowing capacity of $4.9 billion collateralized by the par value of pledged securities totaling $4.9 billion. As of September 30, 2023, the balance outstanding was $4.9 billion consisting of two term advances maturing in March 2024.

Repurchase Agreement. In March of 2023, the Bank entered into a repurchase agreement through which it borrowed $1.4 billion that was collateralized by loans with a principal balance of $2.1 billion. In connection with this borrowing, the Bank incurred $17.9 million of issuance costs and accrued $0.4 million in exit fees. The repurchase agreement is to be repaid with collections on the underlying loans. The repurchase agreement has a term of 18 months, under which the interest rate is 8.50% for amounts outstanding during the first nine months and 8.75% for amounts outstanding during the last nine months. The Bank has the option to pay off the repurchase agreement after the first nine months. Per the terms of the agreement, a reserve account equal to 1.5% of the facility commitment amount was deposited with a third-party bank to be used for certain purposes. Any remaining funds will be returned to PacWest at the time of payoff or maturity of the facility. At September 30, 2023, the borrowing amount outstanding was $1.3 billion collateralized by loans with a principal balance of $2.0 billion.

Credit-Linked Notes. The notes were issued in five classes, each with an interest rate of SOFR plus a spread that ranges from 8.00% to 13.25%, with a weighted average spread of 10.68% at September 30, 2023. The notes are linked to the credit risk of an approximately $2.51 billion reference pool of previously purchased single-family residential mortgage loans at September 30, 2023. The notes are due June 27, 2052. Principal payments on the notes are based only on scheduled and unscheduled principal that is actually collected on these loans. The notes are reported at fair value of $123.8 million at September 30, 2023. See Note 12. Fair Value Option for additional information.

NOTE 10.  DERIVATIVES

To a limited extent, the Company utilizes interest rate swaps contracts with clients and counterparty banks for the purpose of offsetting or hedging exposures arising out of lending and borrowing transactions. The Company offers borrowers interest rate swaps under a "back-to-back" loan hedging program and offsets these "pay floating/receive fixed" contracts with borrowers with "receive fixed/ pay floating" swaps with counterparty banks. The total notional balance of these offsetting hedging contracts was $106.4 million at September 30, 2023. The Company has also hedged the interest rate risk and foreign currency risk on €25.8 million of subordinated debt utilizing a combined cross currency swap/interest rate swap, which has had the effect of hedging the foreign currency risk and fixing the Euribor-based floating rate instrument at a fixed rate of 2.76% through July 2025. The outputs from the Company's NII simulation analysis and MVE modeling reflect the impact of these interest rate/currency swaps, however, the impact is not material. During the year ended December 31, 2022 and the nine months ended September 30, 2023, there were no changes to our hedging program described above.

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 condensed 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. The estimated exposure to loss from these commitments is included in the reserve for unfunded loan commitments, which amounted to $29.6 million at September 30, 2023 and $91.1 million at December 31, 2022.

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.

In addition, we 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 September 30, 2023 and December 31, 2022, we had commitments to contribute capital to these entities totaling $76.6 million and $76.9 million.

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:

Legal Matters

In the ordinary course of our business, the Company is party to various legal actions, which we believe are incidental to the operation of our business. The outcome of such legal actions and the timing of ultimate resolution are inherently difficult to predict. In the opinion of management, based upon currently available information, any resulting liability, in addition to amounts already accrued, 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 12.  FAIR VALUE OPTION

The Company may elect to report financial instruments and certain other items at fair value on an instrument-by-instrument basis with changes in fair value reported in earnings. The election is made upon the initial recognition of an eligible financial asset, financial liability, or firm commitment or when certain specified reconsideration events occur. The fair value election may not otherwise be revoked once an election is made. The changes in fair value are recorded in "Noninterest income" on the condensed consolidated statements of earnings. However, movements in debt valuation adjustments are reported as a component of "Accumulated other comprehensive (loss) income" on the condensed consolidated balance sheets. Debt valuation adjustments represent the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk.

Fair Value Option for Certain Debt Liabilities

The Company has elected the fair value option for the credit-linked notes issued in September 2022. The Company elected the fair value option because these exposures are considered to be structured notes, which are financial instruments that contain embedded derivatives. The notes are linked to the credit risk of an approximately $2.51 billion reference pool of previously purchased single-family residential mortgage loans. The principal balance of the credit-linked notes was $126.1 million at September 30, 2023. The carrying value of the credit-linked notes at September 30, 2023 was the estimated fair value of $123.8 million.

The following table presents the changes in fair value of the credit-linked notes for which the fair value option has been elected for the periods indicated:

NOTE 13.  FAIR VALUE MEASUREMENTS

The Company uses fair value to measure certain assets and liabilities on a recurring basis, primarily securities available-for-sale, derivatives, and certain debt liabilities. 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.

For information regarding the valuation methodologies used to measure our assets recorded at fair value (under ASC Topic 820), and for estimating fair value for financial instruments not recorded at fair value (under ASC Topic 825, as amended by ASU 2016-01 and ASU 2018-03), see Note 1. Nature of Operations and Summary of Significant Accounting Policies and Note 15. Fair Value Measurements to the Consolidated Financial Statements of the Company's Form 10-K.

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 September 30, 2023, the fair value of these investments was $77.8 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:

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 September 30, 2023, the amounts that will actually be realized or paid at settlement or maturity of the instruments could be significantly different.

NOTE 16.  STOCKHOLDERS' EQUITY

Stock-Based Compensation

At the annual meeting of stockholders held on May 11, 2021, the Company's stockholders approved the Amended and Restated PacWest Bancorp 2017 Stock Incentive Plan (the “Amended and Restated 2017 Plan”). The Company’s Amended and Restated 2017 Plan permits stock-based compensation awards to officers, directors, employees, and consultants and will remain in effect until December 31, 2026. The Amended and Restated 2017 Plan authorizes grants of stock-based compensation instruments to issue up to 6,650,000 shares. As of September 30, 2023, there were 2,032,871 shares available for grant under the Amended and Restated 2017 Plan.

Restricted Stock

Restricted stock amortization totaled $0.3 million and $9.5 million for the three months ended September 30, 2023 and 2022 and $12.9 million and $26.1 million for the nine months ended September 30, 2023 and 2022. Such amounts are included in "Compensation expense" on the condensed consolidated statements of earnings. The amount of unrecognized compensation expense related to unvested TRSAs and PRSUs as of September 30, 2023 totaled $49.4 million.

Time-Based Restricted Stock Awards

At September 30, 2023, there were 1,380,848 shares of unvested TRSAs outstanding. TRSAs generally vest ratably over a service period of three or 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 award on the grant date and is recognized over the vesting period using the straight-line method.

Performance-Based Restricted Stock Units

At September 30, 2023, there were 656,049 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 shares underlying 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 200% of target.

Compensation expense related to PRSUs is based on the fair value of the underlying award on the grant 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 or all of the amortization is suspended, or (2) attainment of the financial metrics is improbable, in which case a portion or all 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 to up to 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 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.

Preferred Stock

At September 30, 2023, our preferred stock of $498.5 million represents 20,530,000 depositary shares (the “Depositary Shares”), each representing a 1/40th ownership interest in a share of the Company’s 7.75% fixed rate reset non-cumulative, non-convertible, perpetual preferred stock, Series A, par value $0.01 per share (the “Series A preferred stock”), with a liquidation preference of $1,000 per share of Series A preferred stock (equivalent to $25.00 per Depositary Share). The Series A preferred stock qualifies as Tier 1 capital for purposes of regulatory capital calculations. The Series A preferred stock is perpetual and has no maturity date.

Notes to Condensed Consolidated Financial Statements (Unaudited)

Dividends on the Series A preferred stock are not cumulative or mandatory. If the Company’s Board of Directors does not declare a dividend on the Series A preferred stock in respect of a dividend period, then no dividend shall be deemed to be payable for such dividend period or be cumulative, and the Company will have no obligation to pay any dividend for that dividend period, whether or not the Board of Directors declares a dividend on the Series A preferred stock or any other class or series of its capital stock for any future dividend period. Additionally, so long as any share of Series A preferred stock remains outstanding, unless dividends on all outstanding shares of Series A preferred stock for the most recently completed dividend period have been paid in full or declared and a sum sufficient for the payment thereof has been set aside for payment, no dividend shall be declared or paid or set aside for payment and no distribution shall be declared or made or set aside for payment on the Company’s common stock.

Overview

PacWest Bancorp, a Delaware corporation, is a bank holding company registered under the BHCA and headquartered in Los Angeles, California, with an executive office in Denver, Colorado. 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 a relationship-based community bank focused on providing business banking and treasury management services to small, middle-market, and venture-backed businesses. The Bank offers a broad range of loan and lease and deposit products and services through full-service branches throughout California and in Durham, North Carolina and Denver, Colorado, and loan production offices around the country.

In managing the top line of our business, we focus on loan yield, deposit cost, and net interest margin. Net interest income, on a year-to-date basis in 2023, accounted for 108.7% of net revenue (net interest income plus noninterest income).

At September 30, 2023, the Company had total assets of $36.9 billion, including $22.1 billion of total loans and leases, net of deferred fees, $4.5 billion of securities available-for-sale, $2.3 billion of securities held-to-maturity, and $5.9 billion of interest-earning deposits in financial institutions compared to $41.2 billion of total assets at December 31, 2022, including $28.7 billion of total loans and leases, net of deferred fees, $4.8 billion of securities available-for-sale, $2.3 billion securities held-to-maturity, and $2.0 billion of interest-earning deposits in financial institutions. The $4.4 billion decrease in total assets since year-end was due primarily to a $6.6 billion decrease in loans and leases, net of deferred fees, attributable mainly to loan sales, and a $1.4 billion decrease in goodwill, offset partially by a $3.9 billion increase in interest-earning deposits in financial institutions. See "- Recent Events" for discussion regarding the Company's loan sales during the three months ended June 30, 2023.

61

At September 30, 2023, the Company had total liabilities of $34.5 billion, including total deposits of $26.6 billion and borrowings of $6.3 billion, compared to $37.3 billion of total liabilities at December 31, 2022, including $33.9 billion of total deposits and $1.8 billion borrowings. The $2.8 billion decrease in total liabilities since year-end was due mainly to a $7.3 billion decrease in deposits, offset partially by an increase of $4.5 billion in borrowings, attributable mainly to the $4.9 billion of borrowings made under the Bank Term Funding Program in March 2023.

At September 30, 2023, the Company had total stockholders' equity of $2.4 billion compared to $4.0 billion at December 31, 2022. The $1.6 billion decrease in stockholders' equity since year-end was due mainly to the net loss of $1.42 billion for the nine months ended September 30, 2023 attributable primarily to a $1.38 billion goodwill impairment charge in the first quarter of 2023. Our consolidated common equity Tier 1 (CET1), Tier 1 capital and Total capital ratios increased to 11.23%, 13.84%, and 17.83% at September 30, 2023 due primarily to a decrease in risk-weighted assets.

Recent Events

Loan Sales and Loans Held for Sale

In the second quarter of 2023, we executed on our strategic plan to divest non-core loan portfolios which included selling:

•National Construction portfolio, including $2.6 billion of loans and $2.3 billion of unfunded commitments

•Lender Finance portfolio, including $2.1 billion of loans and $0.2 billion of unfunded commitments

•A portion of the Civic portfolio, including $521 million of loans and $24 million of unfunded commitments

The Lender Finance portfolio was reported as held for sale at March 31, 2023, and this sale reduced the loans held for sale balance in the second quarter. We recorded loan fair value loss adjustments of $171.0 million in the second quarter related to the loans sold and LOCOM HFS adjustments for the loans reported as held for sale at June 30, 2023. We also recorded unfunded commitments fair value loss adjustments of $106.8 million for the unfunded commitments sold. We recorded Civic loan sale charge-offs of $22.4 million related to the sold Civic loans.

The loans held for sale balance at June 30, 2023 was $478.1 million and consisted of National Construction, Lender Finance, and Civic loans. In July 2023, approximately $285 million of National Construction loans were sold with minimal gain/loss. The loans held for sale balance at September 30, 2023 was $188.9 million and consisted almost entirely of Lender Finance loans.

LIBOR Transition Update

Effective July 1, 2023, LIBOR is no longer published for the overnight, one-month, three-month, six-month, and twelve-month settings. Alternative reference rates, including prevailing fall-back indexes adopted by the banking industry, have been incorporated into all legacy LIBOR contracts as part of the Company's LIBOR remediation plan. Any remaining legacy LIBOR contracts as of the third quarter of 2023 are set to transition to their applicable alternate reference rate at their first rate reset date after June 30, 2023.

Banc of California, Inc. Merger Agreement

On July 25, 2023, PacWest announced the signing of a definitive agreement and plan of merger (the "merger agreement") whereby PacWest will merge with Banc of California, Inc. ("Banc" and following the merger, the "combined company") (the "merger"). Upon the terms and subject to the conditions set forth in the merger agreement, at closing each share of common stock of PacWest issued and outstanding immediately prior to the closing (subject to certain exceptions) will be converted into the right to receive 0.6569 of a share of common stock of Banc. In addition, in connection with the closing, each share of Series A preferred stock will be converted into the right to receive one share of a newly created series of preferred stock of Banc having such powers, preferences and rights, and such qualifications, limitations and restrictions, taken as a whole, that are not materially less favorable to the holders of the Series A preferred stock. Concurrently with its entry into the merger agreement, Banc entered into separate investment agreements with affiliates of funds managed by Warburg Pincus LLC (the "Warburg Investors") and certain investment vehicles sponsored, managed or advised by Centerbridge Partners, L.P. (the "Centerbridge Investor" and collectively with the Warburg Investors, the "Investors") to invest, substantially concurrently with the merger closing, in an aggregate of $400 million of shares of Banc common stock and Banc non-voting, common-equivalent stock, and Banc will issue to the Investors warrants to purchase approximately 18.9 million shares of Banc non-voting, common-equivalent stock or shares of Banc common stock (collectively, the "equity investments").

62

Banc, headquartered in Santa Ana, California, is the parent of Banc of California, N.A., with $9.25 billion in assets with 32 offices including 26 full-service branches located throughout Southern California at September 30, 2023. In connection with the merger, Banc of California, N.A. will merge with and into Pacific Western Bank, which will take the Banc of California name and become a Federal Reserve member.

The merger, which was approved by the PacWest and Banc boards of directors, and with respect to which all regulatory approvals have been received as of October 19, 2023, is expected to close on or about November 30, 2023. The transaction remains subject to certain closing conditions, including the closing of the equity investments described above occurring substantially concurrently with the merger closing and requisite approval by the stockholders of each company.

See also the updated "Risk Factors" section disclosed in Part II, Item 1A of this quarterly report on Form 10-Q.

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. While our deposit balances will fluctuate depending on our customers’ liquidity and cash flow, market conditions, and competitive pressures, we seek to minimize the impact of these variances by attracting a high percentage of noninterest-bearing deposits. During 2023, our net interest margin has been negatively impacted because we increased our usage of brokered deposits to replace outflows of non-brokered deposits. Our net interest margin and level of net interest income have been and will be negatively impacted by the sale of the three non-core loan portfolios in the second quarter of 2023. Our current priorities are to increase customer deposits to replace brokered deposits, which will reduce our interest expense, and to reduce operating expenses to offset the expected lower interest income as a result of the loan portfolio sales.

Loan and Lease Production

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. In January 2023, we announced that we were slowing loan growth to preserve capital and strengthen our balance sheet, including winding down our premium finance and multi-family lending groups in the fourth quarter of 2022. In addition, as noted above under “Recent Events—Loan Sales and Loans Held for Sale,” during the second quarter of 2023, we executed on our strategic plan to divest non-core loan portfolios which included selling our National Construction portfolio, Lender Finance portfolio, and a portion of our Civic portfolio.

Our loan origination process emphasizes credit quality. On occasion, to augment our internal loan production, we have purchased loans such as multi-family loans from other banks, private student loans from third-party lenders, and single-family residential mortgage loans. 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.

63

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.

64

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).

The following table presents the calculation of our efficiency ratio for the periods indicated:

Critical Accounting Policies and Estimates

Our accounting policies are fundamental to understanding management’s discussion and analysis of results of operations and financial condition. We identify critical policies and estimates as those that 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 and estimates 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.

Our critical accounting policies and estimates are described in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Form 10-K.

65

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 used the following non-GAAP measures in this Form 10-Q:

•Return on average tangible common equity, tangible common equity ratio, and tangible book value per common 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 common share, respectively.

Third Quarter of 2023 Compared to Third Quarter of 2022

Net (loss) earnings available to common stockholders for the third quarter of 2023 was a loss of $33.3 million, or a loss of $0.28 per diluted share, compared to net earnings available to common stockholders for the third quarter of 2022 of $122.2 million, or $1.02 per diluted share. The $155.5 million decrease in net earnings available to common stockholders from the third quarter of 2022 was due mainly to a $204.5 million decrease in net interest income and a $5.5 million increase in noninterest expense, offset partially by a $3.0 million decrease in provision for credit losses, a $5.2 million increase in noninterest income, and a $46.8 million decrease in income tax expense. The decrease in net interest income was due primarily to our interest-bearing liabilities repricing faster than our interest-bearing assets when interest rates rapidly increased over the last year. Also, the mix of our interest-bearing liabilities changed significantly to higher-cost borrowings and brokered deposits from lower-cost customer deposits, as the closure of three banks in the first half of 2023 caused an outflow of such lower-cost customer deposits. The increase in noninterest expense was due primarily to a $31.1 million increase in insurance and assessments expense, a $14.3 million increase in customer related expense, and a $9.9 million increase in acquisition, integration and reorganization costs, offset partially by a $34.3 million decrease in compensation expense, a $7.6 million decrease in other expense, a $5.1 million decrease in other professional services expense, and a $2.0 million decrease in loan expense. The increase in noninterest income was due mainly to a $14.5 million legal settlement gain in the third quarter of 2023 as compared to a $5.5 million legal settlement gain in the third quarter of 2022. The decrease in income tax expense is due to the income tax benefit recorded on a loss before taxes in the third quarter of 2023, compared to income tax expense recorded on earnings before income taxes in the third quarter of 2022.

Nine Months Ended September 30, 2023 Compared to Nine Months Ended September 30, 2022

Net (loss) earnings available to common stockholders for the nine months ended September 30, 2023 was a loss of $1.45 billion, or a loss of $12.23 per diluted share, compared to net earnings available to common stockholders for the nine months ended September 30, 2022 of $364.7 million, or $3.04 per diluted share. The $1.8 billion decrease in net earnings available to common stockholders from the nine months ended September 30, 2022 was due mainly to a goodwill impairment recorded in the first quarter of 2023 of $1.38 billion. The decrease in net earnings available to common stockholders was also due to a $371.7 million decrease in net interest income, a $141.7 million decrease in noninterest income, a $140.3 million increase in operating expense (excluding the $1.38 billion goodwill impairment and a $30.8 million increase in acquisition, integration and reorganization costs), and a $20.4 million increase in preferred stock dividends, offset partially by a $9.5 million decrease in provision for credit losses and a $261.5 million decrease in income tax expense. The decrease in net interest income was due primarily to our interest-bearing liabilities repricing faster than our interest-bearing assets when interest rates rapidly increased over the last year. Also, the mix of our interest-bearing liabilities changed significantly in the first half of 2023 as the closure of three banks caused an outflow of lower-cost customer deposits, which were replaced with higher-cost borrowings and brokered deposits. The decrease in noninterest income was due mainly to a $158.0 million increase in loss on sale of loans and $11.6 million of LOCOM HFS adjustments on loans held for sale during 2023, offset partially by an $11.6 million increase in dividends and gains on equity investments and a $12.5 million increase in leased equipment income. The increase in operating expense was due primarily to $106.8 million of unfunded commitments fair value loss adjustments in the second quarter of 2023, a $41.2 million increase in customer related expense (higher account analysis expense due to higher earnings credit rate), and a $57.4 million increase in insurance and assessments expense (higher FDIC assessment due to higher assessment rate and higher assessment base), offset partially by a $57.7 million decrease in compensation expense. The increase in preferred stock dividends is due to our preferred stock being issued in June of 2022 and there being no dividends in the nine months ended September 30, 2022. The decrease in income tax expense is due to the income tax benefit recorded on a loss before taxes in the nine months ended September 30, 2023, compared to income tax expense recorded on earnings before income taxes in the nine months ended September 30, 2022.

Third Quarter of 2023 Compared to Third Quarter of 2022

Net interest income decreased by $204.5 million to $130.7 million for the third quarter of 2023 compared to $335.2 million for the third quarter of 2022 due mainly to higher interest expense on deposits and borrowings, offset partially by higher interest income on loans and leases and deposits in financial institutions. The increase in interest expense was due to a higher cost and balance of average interest-bearing liabilities. The increase in interest income on loans and leases was attributable to a higher average balance and higher yield on average loans and leases. The tax equivalent yield on average loans and leases was 5.54% for the third quarter of 2023, compared to 5.12% for the same quarter of 2022. The increase in interest income on deposits in financial institutions was due mainly to a higher rate paid on deposits at the Federal Reserve and a higher average balance.

The tax equivalent NIM was 1.45% for the third quarter of 2023 compared to 3.57% for the comparable quarter last year. The decrease in the tax equivalent NIM was due mostly to a shift in our funding mix beginning in the second half of March 2023 as we responded to the banking crisis to enhance liquidity and protect franchise value. Average borrowings as a percentage of average interest-bearing liabilities was 22% for the third quarter of 2023 compared to 2% for the third quarter of 2022. The additional borrowings are largely short-term in nature, which will allow us to normalize our funding mix over time as economic and market conditions stabilize. The tax-equivalent NIM was further impacted by a higher cost of total deposits and borrowings, offset partially by higher yields on loans and leases and deposits in financial institutions.

The cost of average total deposits was 2.98% for the third quarter of 2023 compared to 0.70% for the third quarter of 2022 due mainly to higher rates and a change in the mix of average deposits, resulting from a decrease in lower cost non-maturity deposits and an increase in higher cost time deposits.

Nine Months Ended September 30, 2023 Compared to Nine Months Ended September 30, 2022

Net interest income decreased by $371.7 million to $596.1 million for the nine months ended September 30, 2023 compared to $967.8 million for the nine months ended September 30, 2022 due mainly to higher interest expense on deposits and borrowings, offset partially by higher interest income on loans and leases and deposits in financial institutions. The increase in interest expense was due to a higher cost and balance of average interest-bearing liabilities. The increase in interest income on loans and leases was attributable to a higher average balance and higher yield on average loans and leases. The tax equivalent yield on average loans and leases was 5.95% for the nine months ended September 30, 2023, compared to 4.82% for the same period in 2022. The increase in interest income on deposits in financial institutions was due mainly to a higher rate paid on deposits at the Federal Reserve and a higher average balance.

The tax equivalent NIM was 2.07% for the nine months ended September 30, 2023 compared to 3.52% for the comparable period last year. The decrease in the tax equivalent NIM was due mostly to a shift in our funding mix beginning in the second half of March 2023 as we responded to the banking crisis to enhance liquidity and protect franchise value. Average borrowings as a percentage of average interest-bearing liabilities was 26% for the nine months ended September 30, 2023 compared to 3% for the nine months ended September 30, 2022. The tax-equivalent NIM was further impacted by a higher cost of total deposits and borrowings, offset partially by higher yields on loans and leases and deposits in financial institutions.

The cost of average total deposits was 2.50% for the nine months ended September 30, 2023 compared to 0.32% for the nine months ended September 30, 2022 due mainly to higher rates and a change in the mix of average deposits, resulting from a decrease in lower cost non-maturity deposits and an increase in higher cost time 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 the allowance for loan and lease losses, the reserve for unfunded loan commitments, and the allowance for credit losses on held-to-maturity securities. 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. For further details on our loan-related allowance for credit losses methodology, see “- Balance Sheet Analysis - Allowance for Credit Losses on Loans and Leases Held for Investment” contained herein.

Third Quarter of 2023 Compared to Third Quarter of 2022

The provision for credit losses decreased by $3.0 million due to no provision for the third quarter of 2023 compared to $3.0 million for the third quarter of 2022. The provision for the third quarter of 2023 was primarily due to an increase in qualitative reserves for loans secured by office properties, which was offset by a reduction in the reserve for unfunded commitments due to a lower unfunded commitments balance. During the third quarter of 2022, the $3.0 million provision was primarily attributable to reserves needed due to a less favorable economic forecast, partially offset by a decrease in COVID-related qualitative reserves.

75

Nine Months Ended September 30, 2023 Compared to Nine Months Ended September 30, 2022

The provision for credit losses decreased by $9.5 million to a provision of $5.0 million for the nine months ended September 30, 2023 compared to $14.5 million for the nine months ended September 30, 2022. The lower provision in the 2023 period is generally due to lower balances of loans and unfunded commitments compared to 2022.

Certain circumstances may lead to increased provisions for credit losses on loans and leases in the future. Examples of such circumstances include deterioration in economic conditions and forecasts, an increased amount of classified and/or criticized loans and leases, and net loan and lease and unfunded commitment growth. Deterioration 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. See further discussion in “- Balance Sheet Analysis - Allowance for Credit Losses on Loans and Leases Held for Investment” contained herein.

Third Quarter of 2023 Compared to Third Quarter of 2022

Noninterest income increased by $5.2 million to an income of $43.8 million for the third quarter of 2023 compared to income of $38.6 million for the third quarter of 2022 due mainly to an increase of $7.0 million in other income, offset partially by lower other commissions and fees of $2.4 million. The increase in other income was primarily due to a $14.5 million legal settlement gain in the third quarter of 2023 as compared to a $5.5 million legal settlement gain in the third quarter of 2022. The decrease in other commissions and fees was primarily due to lower loan-related fees and foreign exchange fees.

Nine Months Ended September 30, 2023 Compared to Nine Months Ended September 30, 2022

Noninterest income decreased by $141.7 million to a loss of $47.9 million for the nine months ended September 30, 2023 compared to income of $93.8 million for the nine months ended September 30, 2022 due mainly to an increase of $158.0 million in the loss on sale of loans and an $11.6 million LOCOM HFS adjustment, offset partially by an increase of $12.5 million in leased equipment income and an increase of $11.6 million in dividends and gains on equity investments. The increase in loss on sale of loans resulted from the sale of $6.1 billion of loans for a net loss of $157.8 million in the nine months ended September 30, 2023 compared to the sale of $60.7 million of loans for a net gain of $130,000 in the nine-month period last year. The LOCOM HFS adjustment was related to the lower of cost or market adjustments that we made to our loans held for sale during the nine months ended September 30, 2023. Dividends and gains (losses) increased due mostly to gains of $7.6 million recorded in 2023 compared to losses of $4.1 million recorded in the nine months ended September 30, 2022 attributable mainly to volatility in equity markets resulting from geopolitical tension and inflationary pressures. The increase in leased equipment income was due mainly to higher early lease termination gains in the 2023 period compared to the 2022 period.

Third Quarter of 2023 Compared to Third Quarter of 2022

Noninterest expense increased by $5.5 million to $201.1 million for the third quarter of 2023 compared to $195.6 million for the third quarter of 2022 due primarily to a $31.1 million increase in insurance and assessments expense, a $14.3 million increase in customer related expense and a $9.9 million increase in acquisition, integration and reorganization costs, offset partially by a $34.3 million decrease in compensation expense, a $7.6 million decrease in other expense, a $5.1 million decrease in other professional services expense and a $2.0 million decrease in loan expense. The increase in insurance and assessments expense was due to higher FDIC assessment expense primarily the result of a higher assessment rate as a result of lower earnings and higher levels of brokered deposits. The increase in customer related expense was due to higher third-party payments for deposit customers for which the Company provides earnings credits due to an increase in the earnings credit rates offered. The increase in acquisition, integration and reorganization costs was due to costs related to the pending merger with Banc. The decrease in compensation expense was due mainly to lower headcount which resulted in lower salaries, commissions, bonus and payroll tax expenses. The decrease in other expense is due to lower operating and legal settlement losses, communications, and employee-related expenses. The decrease in loan expense is due to lower loan-related legal expense and lower loan workout expenses.

77

Nine Months Ended September 30, 2023 Compared to Nine Months Ended September 30, 2022

Noninterest expense increased by $1.5 billion to $2.1 billion for the nine months ended September 30, 2023 compared to $546.7 million for the nine months ended September 30, 2022 due mainly to a $1.38 billion goodwill impairment charge incurred in the first quarter of 2023. Excluding the goodwill impairment charge and acquisition, integration and reorganization costs, operating expenses increased by $140.3 million to $687.0 million in the nine months ended September 30, 2023 as compared to the nine months ended September 30, 2022. The increase was due mainly to a $99.9 million increase in other expense, a $57.4 million increase in insurance and assessments expense, and a $41.2 million increase in customer related expense, offset partially by a $57.4 million decrease in compensation expense. The increase in other expense was due to unfunded commitments fair value loss adjustments of $106.8 million related to unfunded commitments sold in the second quarter of 2023. The increase in insurance and assessments expense was due to higher FDIC assessment expense primarily the result of a higher assessment rate as a result of lower earnings and higher levels of brokered deposits. The increase in customer related expense was due to higher third-party payments for deposit customers for which the Company provides earnings credits due to an increase in the earnings credit rates offered. The decrease in compensation expense was due mainly to lower headcount which resulted in lower salaries, commissions, bonus, and payroll tax expenses.

Income Taxes

The effective tax rate for the third quarter of 2023 was 12.1% compared to 24.9% for the third quarter of 2022. The effective tax rate for the nine months ended September 30, 2023 was 8.7% compared to 25.2% for the nine months ended September 30, 2022. Excluding goodwill impairment of $1.4 billion, the effective income tax rate for the three months and nine months ended September 30, 2023 was 15.9% and 21.7%. The lower effective tax rates for the three months and nine months ended September 30, 2023 compared to those for the three months and nine months ended September 30, 2022 were due primarily to the higher disallowed FDIC assessment expense and disallowed interest expense in 2023. The Company's blended statutory tax rate for federal and state is 27.6%.

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, the provision for unfunded loan commitments, and the provision for held-to-maturity debt securities.

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, see Note 1. Nature of Operations and Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data" of our Form 10-K.

In calculating our allowance for credit losses, we continued to consider higher inflation rates, rising interest rates, the risk of a recession, technical or otherwise, and the Russia-Ukraine war as well as any trailing impact of the COVID-19 pandemic in our process for estimating 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 resulting from such events. 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.

For the third quarter of 2023, we used the Moody’s September 2023 Baseline, S1 Upside 10th Percentile, and S3 Downside 90th Percentile forecast scenarios for the calculation of our quantitative component. The weightings of the scenarios were based on management’s current expectations for the economic forecast, acknowledging the risk of a near-term recession and inherent uncertainty. Compared to the second quarter of 2023, the economic forecasts were relatively consistent, resulting in an immaterial impact to the allowance for credit losses.

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. During the first quarter of 2021, we added qualitative components that were based on management’s assessment of various qualitative factors such as economic conditions and collateral dependency. These qualitative components were primarily related to certain loan portfolios including hotels, retail, and office properties that were more directly affected by the COVID-19 pandemic and may react more slowly to the improvements in the general economic conditions. Business operations and collateral valuations in these industries have stabilized with the exception of office properties for which there is continued uncertainty regarding the longer-term impact of remote working and flexible/hybrid work environments.

During the third quarter of 2023, the increase in qualitative adjustments for loans secured by office properties was offset by net charge-offs and lower reserves needed for lower loan and unfunded commitment balances resulting in no net provision for credit losses.

83

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. We calculated alternative values for our September 30, 2023 ACL using various alternative forecast scenarios provided by Moody’s including the Moody’s S1 Upside 10th Percentile and S3 Downside 90th Percentile and the calculated amounts for the quantitative component differed from the probability-weighted multiple scenario forecast ranging from lower by 6.34% to higher by 26.39%. 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 on loans and leases held for investment 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.

Management believes the allowance for credit losses is appropriate for the current expected credit losses in our loan and lease portfolio and associated unfunded loan 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 financial statements.

During the nine months ended September 30, 2023, nonaccrual loan and leases held for investment increased by $21.6 million to $125.4 million at September 30, 2023 due mainly to additions of $113.9 million, offset partially by principal and other reductions including sales of $71.6 million, charge-offs of $17.7 million, and transfers to accrual status of $3.0 million. As of September 30, 2023, the Company's three largest loan relationships on nonaccrual status had an aggregate carrying value of $20.5 million and represented 16% of total nonaccrual loans and leases.

Loans and leases accruing 30-89 days past due generally fluctuate from period to period. The $61.0 million decrease to $38.0 million as of September 30, 2023 was due mainly to a decrease in Civic delinquent loans.

Total loans and leases held for investment, net of deferred fees	$	21,920,946	$	28,609,129

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.

The increase in classified loans during the nine months ended September 30, 2023, was driven by downgrades in Multi-family loans as the result of rising interest rates and the related stress on debt service. The decrease in special mention loans during the nine months ended September 30, 2023 was due mainly to decreases in construction loans and asset-based loans resulting mostly from loan sales in the second quarter of 2023.

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 September 30, 2023, banks considered to be “well capitalized” must maintain a minimum Tier 1 leverage ratio of 5.00%, a minimum common equity Tier 1 risk-based capital ratio of 6.50%, a minimum Tier 1 risk-based capital ratio of 8.00%, and a minimum Total risk-based capital ratio of 10.00%. Regulatory capital requirements limit the amount of deferred tax assets that may be included when determining the amount of regulatory capital. Deferred tax asset amounts in excess of the calculated limit are disallowed from regulatory capital. At September 30, 2023, such disallowed amounts was $55.8 million for the Company. No assurance can be given that the regulatory capital deferred tax asset limitation will not increase in the future or that the Company will not have increased deferred tax assets that are disallowed.

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 September 30, 2023, the Company and the Bank were in compliance with the capital conservation buffer requirement.

92

The Company and the Bank elected the CECL 5-year regulatory transition guidance for calculating regulatory capital ratios and the September 30, 2023 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, 2021. This cumulative amount is now being phased out of regulatory capital evenly over the three years from 2022 to 2024. The add-back as of September 30, 2023 ranged from 0 basis points to 6 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:

The Company's consolidated common equity Tier 1 (CET1), Tier 1, and Total capital ratios increased during the nine months ended September 30, 2023 due mainly to positive adjusted earnings combined with a decrease in risk-weighted assets. The consolidated Tier 1 leverage ratio increased during the nine months ended September 30, 2023 due mainly to a decrease in average assets attributable primarily to loan sales.

Subordinated Debt

We issued or assumed through mergers subordinated debt to trusts that were established by us or entities we acquired, which, in turn, issued trust preferred securities. As of September 30, 2023, the carrying value of subordinated debt totaled $870.9 million. At September 30, 2023, $131.0 million of the trust preferred securities were included in the Company's Tier I capital and $725.6 million were included in Tier II capital.

Dividends on Common Stock and Interest on Subordinated Debt

As a bank holding company, PacWest is required to notify and receive approval from the FRB prior to declaring and paying a dividend to common 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 debt 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. The Company currently is required to receive FRB approval to declare or pay a dividend to stockholders. Further, if the Company defaults or elects to defer the interest payments on its subordinated debt, it is restricted from paying dividends on its Series A preferred and common stock.

Dividends on Preferred Stock

The Company's ability to pay dividends on the Series A preferred stock depends on the ability of the Bank to pay dividends to the holding company. The ability of the Company and the Bank to pay dividends in the future is subject to bank regulatory requirements, including capital regulations and policies established by the FRB, the FDIC and the DFPI, as applicable. Dividends on the Series A preferred stock will not be declared, paid, or set aside for payment to the extent such act would cause us to fail to comply with applicable laws and regulations, including applicable FRB capital adequacy regulations and policies.

Dividends on the Series A preferred stock are not cumulative or mandatory. If the Company’s Board of Directors does not declare a dividend on the Series A preferred stock in respect of a dividend period, then no dividend shall be deemed to be payable for such dividend period or be cumulative, and the Company will have no obligation to pay any dividend for that dividend period, whether or not the Board of Directors declares a dividend on the Series A preferred stock or any other class or series of its capital stock for any future dividend period. Additionally, so long as any share of Series A preferred stock remains outstanding, unless dividends on all outstanding shares of Series A preferred stock for the most recently completed dividend period have been paid in full or declared and a sum sufficient for the payment thereof has been set aside for payment, no dividend shall be declared or paid or set aside for payment and no distribution shall be declared or made or set aside for payment on the Company’s common stock.

Liquidity

Liquidity Management

Liquidity is the ongoing ability to accommodate liability maturities and deposit withdrawals, fund asset growth and business operations, and meet contractual obligations through unconstrained access to funding at reasonable market rates. Liquidity management involves forecasting funding requirements and maintaining sufficient capacity to meet the needs and accommodate fluctuations in asset and liability levels due to changes in the Company’s business operations or unanticipated events.

We have an Executive Management Asset/Liability Management Committee ("Executive ALM Committee") that is comprised of members of senior management and is responsible for managing commitments to meet the needs of customers while achieving our financial objectives. Our Executive ALM Committee meets regularly to review funding capacities, current and forecasted loan demand, and investment opportunities.

We manage our liquidity by maintaining pools of liquid assets on-balance sheet, consisting of cash and receivables due from banks, interest-earning deposits in other financial institutions, and unpledged securities, on-balance sheet, 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.

94

As a member of the FHLB, the Bank had secured borrowing capacity with the FHLB of $4.3 billion at September 30, 2023, and nothing was borrowed as of that date. The FHLB secured credit line was collateralized by a blanket lien on $8.5 billion of certain qualifying loans and $18.4 million of securities. The Bank also had secured borrowing capacity with the FRBSF under the Discount Window program totaling $6.5 billion at September 30, 2023, all of which was available, and $4.9 billion under the Bank Term Funding Program, which was fully borrowed as of that date. The FRBSF Discount Window secured credit line was collateralized by liens on $6.8 billion of qualifying loans and $1.5 billion of pledged securities, and the Bank Term Funding Program credit line was collateralized by pledged securities with a market value of $4.1 billion and a par value of $4.9 billion. The Bank Term Funding Program provides borrowing capacity on qualifying government and government agency guaranteed securities based on the collateral par value.

In addition to its secured lines of credit with the FHLB and FRBSF, the Bank also borrowed $1.3 billion under a repurchase agreement facility, which was collateralized by $2.0 billion of loan collateral. The Bank also maintains unsecured lines of credit for the purpose of borrowing overnight funds, subject to availability, of $100.0 million in the aggregate with several correspondent banks. As of September 30, 2023, 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 September 30, 2023, there was no outstanding balance through the AFX.

Total secondary liquidity	$	10,806,179	$	6,959,587

During the nine months ended September 30, 2023, the Company's primary liquidity increased by $75.5 million to $6.4 billion at September 30, 2023 due mainly to a $3.9 billion increase in interest-earning deposits in financial institutions, offset partially by increases of $3.0 billion in pledged AFS securities and $267.2 million in pledged HTM securities. During the nine months ended September 30, 2023, the Company's secondary liquidity increased by $3.8 billion to $10.8 billion at September 30, 2023 due mainly to an increase in available secured borrowing capacity with the FRBSF of $4.1 billion, offset partially by a decrease in available secured borrowing capacity with the FHLB of $226.3 million.

95

During the first six months of 2023, the Company was subject to multiple liquidity stress events that resulted in significant changes in liquidity levels and funding structure. The stress stemmed from the deposit outflow after the failure of two regional banks, which caused ripple effects in the banking industry and adversely affected the Company due to the perceived similar business profile between it and the two regional banks that failed. The Company experienced deposit outflows of $6.5 billion or 19% of deposits over the period March 10 to March 17, 2023. The Company experienced a second round of significant deposit outflows over the period May 1 to May 5, 2023, with an additional $2.5 billion of total deposits lost after the failure of another regional bank.

In light of these developments, management activated the Company's contingency funding plan on March 10, 2023 and took actions to stem the deposit outflows and bolster liquidity. Eventually, all available assets were pledged to borrowing lines at the FHLB and FRBSF. In addition, management executed a $1.4 billion repurchase agreement collateralized by previously unpledged loans to further increase liquidity. Furthermore, management utilized brokered deposits as a funding source to fill deposit gaps. Although management realized the more expensive brokered deposits and borrowings would result in lower net interest income, management prioritized increasing liquidity to address deposit outflows and the potential for further deposit outflows.

In addition to the above, management took other actions including: (1) announcing on May 5, 2023 the reduction in the quarterly dividend on PacWest common stock from $0.25 per share to $0.01 per share, (2) increasing the number of customers enrolled in reciprocal deposit programs, which increases the amount of FDIC insurance coverage on their account(s), to help retain these customers, (3) offering competitive promotional rates on deposit products to attract new customer deposits, and (4) beginning to reposition the Company's balance sheet and asset/liability maturity profile by reclassifying our $2.7 billion Lender Finance loan portfolio to held for sale at March 31, 2023, with the intention of selling the portfolio in the second quarter of 2023 to increase immediately available liquidity.

Notwithstanding these steps, management took other actions to address liquidity shortfalls in the second quarter of 2023, including: (1) selling our $2.6 billion National Construction loan portfolio, (2) selling $521 million of our Civic loan portfolio, (3) completing the sale of $2.1 billion of the Lender Finance loan portfolio, (4) introducing a digital account opening tool for new customers to more easily open a deposit account, and (5) partnering with a third-party vendor to begin listing PacWest's deposit products on the vendor's online marketplace in the third quarter of 2023. Management also increased the amount of time deposits on-balance sheet through both core customer and brokered channels, including long-term callable brokered certificates of deposit, to increase liquidity and to help address timing differences in the maturity and repricing of assets and liabilities.

At the end of the second quarter of 2023, with the sale of the non-core loan portfolios completed, the Company believed it had addressed the liquidity risk present at the end of the first quarter and had also improved its capital ratios. Immediately available liquidity (on-balance sheet liquidity and unused borrowing capacity) was $17.9 billion at June 30, 2023, which exceeded uninsured deposits of $5.3 billion, with a coverage ratio of 335% as compared to a coverage ratio of 153% at March 31, 2023. Immediately available liquidity also represented 64% of total deposits at June 30, 2023.

All of the aforementioned actions taken by management helped to increase customer deposits in the later part of the second quarter and in the third quarter. Immediately available liquidity was $16.7 billion at September 30, 2023, which exceeded uninsured deposits of $5.0 billion, with a coverage ratio of 332%. Immediately available liquidity also represented 63% of total deposits at September 30, 2023. However, at September 30, 2023, despite the progress made, the Company was still not in compliance with all of its funding concentration liquidity guidelines as outlined below.

The Company's net interest margin and overall profitability were reduced as a result of the loan sales, and continue to be affected by elevated levels of higher-cost brokered deposits and borrowings. Obtaining new customer deposits, or having existing customers increase their deposit balances with us, are the primary sources of funding for our operations and is one the highest priorities of the Company. See "- Balance Sheet Analysis - Deposits" for additional information and detail of our deposits. Additionally, we fund our operations with cash flows from our loan and securities portfolios.

Our deposit balances may decrease if customers withdraw funds from the Bank. In order to address the Bank’s liquidity risk from fluctuating deposit balances, the Bank maintains adequate levels of available liquidity on and off the balance sheet.

96

We use brokered deposits, the availability of which is uncertain and subject to competitive market forces and regulation, for liquidity management purposes. At September 30, 2023, brokered deposits totaled $5.7 billion, consisting of $1.7 billion of non-maturity brokered accounts and $4.1 billion of brokered time deposits. At December 31, 2022, brokered deposits totaled $4.9 billion, consisting of $2.6 billion of non-maturity brokered accounts and $2.3 billion of brokered time deposits.

Our liquidity policy includes guidelines, which are governed by the Company's Risk Appetite Statement, for the following metrics: 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 metrics developed for measuring and maintaining liquidity. At September 30, 2023, the Bank was not in compliance with all of its funding concentration liquidity guidelines due primarily to the elevated balances of brokered deposits and borrowings in relation to total deposits and to total liabilities.

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 debt. See "- Regulatory Matters - Dividends on Preferred Stock" for information regarding the payment of dividends on the Series A preferred stock.

At September 30, 2023, PacWest had $287.1 million in cash and cash equivalents, of which a substantial amount was 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.

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 September 30, 2023, our loan commitments and standby letters of credit were $5.3 billion and $265.2 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 11. Commitments and Contingencies, of the Notes to Condensed Consolidated Financial Statements (Unaudited) contained in "Item 1. Condensed Consolidated Financial Statements (Unaudited)."

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

This analysis should be read in conjunction with text under the caption "Quantitative and Qualitative Disclosures About Market Risk" in our Form 10-K, which text is incorporated herein by reference. Our analysis of market risk and market-sensitive financial information contains forward-looking statements and is subject to the disclosure at the beginning of Item 2 regarding such forward-looking information.

Market Risk - Foreign Currency Exposure

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 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 September 30, 2023, the U.S. Dollar notional amounts of loans receivable and subordinated debt payable denominated in foreign currencies were $8.5 million and $27.3 million, and the U.S. Dollar notional amounts of derivatives outstanding to hedge these foreign currency exposures were $8.7 million and $28.5 million. We recognized a foreign currency translation net loss of $97,000 for the nine months ended September 30, 2023 and a foreign currency translation net gain of $2.1 million for the nine months ended September 30, 2022.

Asset/Liability Management and Interest Rate Sensitivity

Interest Rate Risk – Company Governance

The Company's board of directors oversees, and annually approves, upon recommendation of its Risk Committee, the Risk Appetite Statement. The Risk Appetite Statement sets forth "low," "medium," and "high" risk ranges for interest rate risk ("IRR"), based on the proximity of reported results to pre-established limits (the "IRR Limits") set forth in the Company's Asset Liability Management Policy (the "ALCO Policy"). Generally, the "low" range represents measured results less than or equal to 50% of the policy limit, the "medium" range represents measured results approximately 50% to 80% of the policy limit, and the "high" range represents measured results greater than 80% of the policy limit.

On a monthly basis, we measure our IRR position using two methods: (i) Net Interest Income (“NII”) simulation analysis and (ii) Market Value of Equity (“MVE”) modeling. The Executive Asset-Liability Management (“ALM”) Committee and the Finance Committee of the Company's board of directors review the results of these analyses at least quarterly. As discussed in more detail below, if projected changes to interest rates cause changes to our simulated net present value of equity and/or net interest income outside our pre-established IRR limits, we may adjust our asset and liability mix in an effort to bring our interest rate risk exposure within our established limits.

The pre-established IRR Limits are recommended by management, determined based on analytical review and available peer data published by regulatory agencies about the IRR Limits utilized by other regional banks, and documented in the Company’s ALCO Policy. The ALCO Policy is approved by the Executive ALM Committee and the Finance Committee of the board of directors annually. The most recent board committee approval occurred at the board Finance Committee meeting on February 7, 2023. We believe our ALCO Policy IRR Limits are consistent with prevailing practice in the regional banking industry. Historically, there have not been material changes to the IRR Limits from year-to-year, and there were no changes to the IRR Limits during the year ended December 31, 2022 and the nine months ended September 30, 2023.

98

The following table summarizes the IRR Limits stated in our ALCO Policy as of December 31, 2022 and September 30, 2023:

We use a balance sheet simulation model (the “IRR Model”) to estimate changes in NII and MVE that would result from immediate and sustained changes in interest rates as of the measurement date. This IRR Model assesses the changes in NII and MVE that would occur in response to an instantaneous and sustained increase and decrease in market interest rates of 100, 200, 300, and 400 basis points. This model is an IRR management tool, and the results are not necessarily an indication of our future net interest income. The IRR Model has inherent limitations and the model’s results are based on a given set of rate changes and assumptions at a single point in time.

The IRR Model is updated monthly (except January and July), and the IRR Model results are reported to the Executive ALM Committee and the Finance Committee of the Company's board of directors at each monthly or quarterly meeting, as applicable. From January 2022 through February 2023, the IRR Model results were within IRR Limits and reflected generally "low" estimated interest rate risk. The unanticipated deposit outflows that the Company experienced in March through May 2023 resulted in a material change to the Company’s funding mix, with approximately $9.0 billion of customer deposits withdrawn and replaced by more rate-sensitive brokered deposits and borrowings. When the funding mix shift occurred, interest rate risk increased, and when we reported the results of the March 2023 IRR model to the Executive ALM Committee and the Finance Committee of the Company's board of directors, management noted that the risk had shifted to the high-risk range in some categories. In response to being notified of the increase in risk, each of the committees requested, and received, frequent updates from management on developments with respect to the IRR, and the committee members spent significant time discussing alternative strategies to manage IRR. In June 2023, management immediately reported to the committees that the IRR Limits had been breached, meaning that the measured change was greater than that allowable by the IRR Limits. At no point did the Executive ALM Committee or the Finance Committee of the Company's board of directors approve a risk profile that did not conform to the risk tolerances of management or the Company's board of directors.

The ALCO Policy requires that management provide immediate notice to the Executive ALM Committee and Finance Committee upon determining that IRR Limits have been breached and the exceptions are material to the Company. Further, the ALCO Policy requires management to formulate a plan to correct the policy exceptions. During the banking stress event from March through May 2023, management continually kept the Executive ALM Committee and Finance Committee informed of the IRR and liquidity stresses the Company was facing. As previously discussed in the "Liquidity Management" section, management formulated a strategic plan to retain customers and attract new customer deposits and, consistent with its previously disclosed strategy, the Company began to reposition the balance sheet by selling certain large loan pools. These actions were designed to improve liquidity and the IRR profile of the Company over time. The merger with Banc of California, Inc. is also expected to reduce the interest rate risk of the merged institution by increasing capital, reducing the volume of fixed-rate assets, and paying down borrowings and brokered deposits.

Interest Rate Risk

We evaluated the results of our NII simulation model and MVE model prepared as of September 30, 2023, which are presented below. Our NII simulation and MVE model indicate that our balance sheet is liability sensitive. A liability sensitive IRR profile would suggest that our estimated NII and MVE would change in the opposite direction of a sudden sustained change in prevailing interest rates.

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 September 30, 2023. 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. For the current quarter, the results of the NII simulation model are exaggerated by the large cash and borrowings positions that existed on September 30, 2023.

This analysis calculates the difference between NII forecasted using both increasing and decreasing interest rate scenarios using the forward yield curve at September 30, 2023. In order to arrive at the base case, we extend our balance sheet at September 30, 2023 one year and reprice any assets and liabilities that would contractually reprice or mature during that period using the products’ pricing as of September 30, 2023. Based on such repricing, we calculate an estimated NII and NIM for each rate scenario.

The NII simulation model is dependent upon numerous assumptions. For example, 30% of our loans are variable-rate and 26% are hybrid adjustable-rate mortgage loans, which 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 September 30, 2023 assumes interest-bearing deposits reprice at 56% and total deposits reprice at 45% 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, interest rate floors on variable-rate loans, 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 as of September 30, 2023 and forward yield curve as of September 30, 2023 as the base scenario, with immediate and sustained parallel upward and downward movements in interest rates of 100, 200, and 300 basis points as of the date indicated:

	Forecasted			Forecasted	Forecasted

During the nine months ended September 30, 2023, total base case year 1 tax equivalent NII decreased by $694.2 million or 54% to $581.1 million at September 30, 2023 compared to December 31, 2022, and the base case tax equivalent NIM decreased to 1.67% at September 30, 2023 from 3.21% at December 31, 2022. The decrease in year 1 NII and tax equivalent NIM compared to the December 31, 2022 forecasted NII and NIM was attributable to the increase in prevailing interest rates driving higher interest expense on deposits and borrowings, the decrease in average interest earning assets from loan sales driving lower interest income, and the change in the funding mix at September 30, 2023 compared to December 31, 2022 driving higher interest expense. The average balance of noninterest-bearing deposits decreased by $6.0 billion, the average balance of interest-bearing deposits decreased by $1.3 billion, and the average balance of borrowings increased by $4.4 billion. These changes in prevailing interest rates and balance sheet composition resulted in a $305 million decrease in forecasted interest income and a $389 million increase in forecasted interest expense. The changes in the balance sheet composition at September 30, 2023 from December 31, 2022 was in response to recent industry events.

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 “Gradual Decrease” scenario, which applies a parallel ramped decrease to the yield curve over an 18-month horizon. In the “Gradual Decrease” scenario, Year 1 tax equivalent NII increases by 3.1%. The most unfavorable alternate rate vector that we model is the “Gradual Increase” scenario, in which rates increase over an 18-month ramped horizon. In the “Gradual Increase” scenario, Year 1 tax equivalent NII decreases by 2.7%.

At September 30, 2023, we had $22.1 billion of total gross loans that included $6.7 billion or 30% with variable interest rate terms (excluding hybrid loans discussed below). Of the variable interest rate loans, $5.70 billion, or 85%, contained interest rate floor provisions, which included $5.69 billion of loans that were at or above their floors and only $12.9 million of loans below their floors.

At September 30, 2023, we also had $5.8 billion of variable-rate hybrid loans, representing 26% of total loans, which do not reprice immediately 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 $105.8 million, $602.7 million, and $1.7 billion in the next one, two, and three years.

LIBOR was phased out on June 30, 2023, as such the Company stopped originations of LIBOR-indexed loans effective December 31, 2021. The business processes impacted relate primarily to our variable-rate loans and our subordinated debt, both of which were indexed to LIBOR. For further information, see Item 7A. "Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, 2022.

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 and decrease in market interest rates of 100, 200, and 300 basis points. This analysis assigns significant value to our noninterest-bearing deposit balances. The projections include various assumptions regarding cash flows and interest rates and are by their nature forward-looking and inherently uncertain.

The MVE model is an interest rate risk management tool and the results are not necessarily an indication of our actual future results. Actual results may vary significantly from the results suggested by the market value of equity table. Loan prepayments and deposit attrition, changes in the mix of our earning assets or funding sources, and future asset/liability management decisions, among others, may vary significantly from our assumptions. The base case is determined by applying various current market discount rates to the estimated cash flows from the different types of assets, liabilities, and off-balance sheet items existing at September 30, 2023.

____________________________________ 

(1)    The ratio of base case of projected MVE to the Company's total stockholders' equity was 1.71 at September 30, 2023 and 2.15 at December 31, 2022 The MVE methodology and the application of the various assumptions as of September 30, 2023 are consistent with December 31, 2022.

During the nine months ended September 30, 2023, total base case projected market value of equity decreased from December 31, 2022 by $4.4 billion to $4.1 billion at September 30, 2023. This decrease in base case projected MVE was due mostly to: (1) a $2.8 billion decrease in the estimated market value of deposits, borrowings, and subordinated debt; (2) a $369.7 million decrease in the market value of investment securities held-to-maturity; and (3) a $1.55 billion decrease in the book value of stockholders' equity; offset partially by (4) a $290.9 million increase in the estimated market value of loans and leases. The decrease in the book value of stockholders' equity was due mainly to a $1.42 billion net loss attributable primarily to a $1.38 billion goodwill impairment charge, $31.4 million of common stock cash dividends paid, and an $82.8 million increase in accumulated other comprehensive loss.

ITEM 4. CONTROLS AND PROCEDURES

As of the end of the period covered by this report, an evaluation was carried out by the Company's management, with the participation of the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the Company's disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, these disclosure controls and procedures were effective.

There have been no changes in the Company's internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization

ORGANIZATION    

PacWest Bancorp, a Delaware corporation, is a bank holding company registered under the BHCA and headquartered in Los Angeles, California, with an executive office in Denver, Colorado. 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 a relationship-based community bank focused on providing business banking and treasury management services to small, middle-market, and venture-backed businesses. The Bank offers a broad range of loan and lease and deposit products and services through full-service branches throughout California and in Durham, North Carolina and Denver, Colorado, and loan production offices around the country.

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 interest paid by the Bank on deposits and borrowings, compensation, occupancy, and general operating expenses.

Significant Accounting Policies

Our accounting policies are described in Note 1. Nature of Operations and Summary of Significant Accounting Policies, of our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2022 as filed with the Securities and Exchange Commission ("Form 10-K"). Updates to our significant accounting policies described below reflect the impact of the adoption of ASU 2022-02, "Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures ("ASU 2022-02")," specifically the amendment to troubled debt restructurings, and organizational changes which resulted in changes to our reportable operating segments.

Loan Modifications to Borrowers Experiencing Financial Difficulty

Loan modifications made to borrowers experiencing financial difficulty constitute modifications of receivables in the form of principal forgiveness, an interest rate reduction, an other than-insignificant payment delay, or a term extension. ASU 2022-02 eliminated the concept of troubled debt restructurings and introduced broader modification reporting requirements. Previously, troubled debt restructurings included any type of modification that included a below market concession which was granted both to a borrower in financial difficulty and as a result of financial difficulty. Loan modifications made to borrowers experiencing financial difficulty no longer consider whether a market concession has been granted, as was required with troubled debt restructurings, but rather includes as modifications within the four listed reportable modification types to a borrower deemed to be experiencing financial difficulty. An assessment of whether a borrower is experiencing financial difficulty is made on the date of the modification. Loans reported in this classification have a rating of substandard or worse, and may include both accruing and nonaccruing loans. Loans are assessed to determine whether the modification constitutes a new loan or a continuation of the existing loan. Depending on the terms of the modification and nature of the borrower, this may result in a downgrade or placing a loan on nonaccrual status, which in turn would impact the loan's classification within the ALLL. Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses because of the measurement methodologies used to estimate the allowance, a change to the allowance for credit losses is generally not recorded upon modification.

Business Segments

We regularly assess our strategic plans, operations, reporting structures and financial information provided to management to identify our reportable segments. Civic, a lending subsidiary we acquired in February 2021, has historically been identified as an operating segment. In the fourth quarter of 2022, Civic met a quantitative threshold which required it to be disclosed as a reportable operating segment. Therefore, we had two reportable operating segments as of December 31, 2022: Commercial Banking and Civic, and a third segment, Other, which was used for inter-segment eliminations. In the first quarter of 2023, we began a restructuring of Civic which included removing most of Civic's top management and transferring day-to-day management of most of Civic's operating functions to managers at the Bank. Due to the restructuring of Civic, discrete financial information is no longer prepared. Our management reporting captures the direct expenses of Civic, however, none of the expenses now being incurred to manage Civic are being directly charged or allocated to Civic. Therefore, it is no longer feasible to produce meaningful, separate full financial statements, and thus, discrete financial information for Civic is no longer prepared or distributed to our chief operating decision maker. Thus, Civic no longer meets the criteria to be considered a reportable operating segment as of March 31, 2023. We sold the Civic business in the second quarter of 2023, and we are retaining and servicing the Civic loans on our balance sheet. At September 30, 2023, June 30, 2023, and March 31, 2023, we operated as one reportable segment - Commercial Banking.

Accounting Standards Adopted in 2023

Effective January 1, 2023, we completed the adoption of ASU 2022-02, “Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures," by eliminating the accounting guidance for TDRs by creditors, in ASC 310-40, "Receivables – Troubled Debt Restructurings by Creditors," while enhancing disclosure requirements for restructurings involving borrowers that are experiencing financial difficulty. The Company updated its disclosures in Note 4. Loans and Leases to present information regarding loan modifications to borrowers experiencing financial difficulty. There was no transition adjustment recorded to retained earnings upon adoption. The adoption of this amendment did not have a material impact on the Company’s condensed consolidated financial statements.

Basis of Presentation    

Our interim condensed consolidated financial statements are prepared in accordance with U.S. GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, certain disclosures accompanying annual consolidated financial statements are omitted. In the opinion of management, all 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 for the interim periods, have been included. The current period's results of operations are not necessarily indicative of the results that ultimately may be achieved for the year. The interim condensed consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Form 10-K.

Use of Estimates

We have made a number of estimates and assumptions related to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period to prepare these condensed consolidated financial statements in conformity with U.S. GAAP. 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 intangible assets, the fair value of loans held for sale, and the realization of deferred tax assets. These estimates may be adjusted as more current information becomes available, and any adjustment may be significant.

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 certain of our loan portfolio classes and subclasses to better reflect and report our lending. We made the following changes: (1) moved the "Multi-family" loan subclass from the residential real estate mortgage class into its own loan class; (2) moved the "Construction - renovation" loan subclass from the residential real estate construction and land loan class to the residential real estate mortgage class and renamed it "Residential renovation;" and (3) renamed the residential real estate mortgage loan class as "Other residential." All of the loan and allowance tables, both current period and prior periods, reflect these changes and realignment.

Risks and Uncertainties

The bank failures earlier in 2023 involving three prominent regional banks resulted in significant market volatility among publicly traded bank holding companies, and, in particular, regional banks like PacWest. These bank failures, and the resulting customer fear of additional bank failures, increased the following risks and uncertainties regarding our business: (i) the loss of customer deposits which, in turn, put pressure on our liquidity position, (ii) the decrease in our net interest margin resulting from replacing lower-cost customer deposits with higher-cost brokered deposits and borrowings, (iii) the downgrading of our credit rating by third-party rating agencies which may result in increased borrowing costs and/or trigger additional collateral or funding requirements, and (iv) the increase in operating costs due to higher FDIC assessments and other costs necessary to respond to increased regulatory requirements.

To respond to these increased risks and uncertainties, we have taken the following actions to mitigate these risks: (a) we pledged additional assets as collateral for borrowings to increase our liquidity position for potential deposit outflows, (b) we increased the number of customers enrolled in reciprocal deposit programs that increases the amount of FDIC insurance coverage on their account(s) to help retain these customers, (c) we are offering competitive promotional rates on our deposit products to attract new customer deposits, (d) we completed strategic asset sales in the second quarter of 2023 to improve our liquidity position and capital ratios, and (e) in the second quarter of 2023, we reduced our common dividend from $0.25 to $0.01 to improve our liquidity position and capital ratios.

As of September 30, 2023, the Company had not recorded an allowance for credit losses on securities available-for-sale. The Company does not consider unrealized losses on such securities to be attributable to credit-related factors, as the unrealized losses have occurred as a result of changes in non-credit related factors such as interest rates, market spreads, and market conditions subsequent to purchase.

As of September 30, 2023, securities available-for-sale with a fair value of $4.2 billion were pledged as collateral primarily for the Bank Term Funding Program borrowings, the FRB secured line of credit, and letters of credit.

The securities that were in an unrealized loss position at September 30, 2023, were considered impaired and required further review to determine if the unrealized losses were credit-related. We concluded the 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 "Accumulated other comprehensive (loss) income" of "Stockholders' equity" on the condensed consolidated balance sheets. Although we periodically sell securities for portfolio management purposes, we do not foresee having to sell any impaired securities 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.

CMBS, CMOs, and MBS 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.

Credit losses on HTM securities are recorded at the time of purchase, acquisition, or when the Company designates securities as held-to-maturity. Credit losses on HTM securities are representative of current expected credit losses that may be incurred over the life of the investment. Accrued interest receivable on HTM securities, which is included in other assets on the condensed consolidated balance sheets, is excluded from the estimate of expected credit losses. HTM U.S. treasury securities and agency-backed MBS securities are considered to have no risk of loss as they are either explicitly or implicitly guaranteed by the U.S. government. The change in fair value in the HTM private label CMBS portfolio is solely driven by changes in interest rates. The Company has no knowledge of any underlying credit issues and the cash flows underlying the debt securities have not changed and are not expected to be impacted by changes in interest rates and, thus, there is no related ACL for this portfolio. The underlying bonds in the Company’s HTM municipal securities and HTM corporate debt securities portfolios are evaluated for credit losses in conjunction with management’s estimate of the allowance for credit losses based primarily on credit ratings.

Securities Held-to-Maturity by Credit Quality Indicator

The Company uses S&P, Moody's, Fitch, Kroll, and Egan Jones ratings as the credit quality indicators for its held-to-maturity securities. The following table presents our securities held-to-maturity portfolio at amortized cost by the lowest available credit rating as of the dates indicated:

Commercial MBS 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.

Loans and Leases

LOANS AND LEASES

Our loans are carried at the principal amount outstanding, net of deferred fees and costs, and in the case of acquired and purchased loans, net of purchase discounts and premiums. Deferred fees and costs and purchase discounts and premiums on acquired loans are recognized as an adjustment to interest income over the contractual life of the loans primarily using the effective interest method or taken into income when the related loans are paid off or included in the carrying amount of loans that are sold.

It is our policy to discontinue accruing interest when principal or interest payments are past due 90 days or more (unless the loan is both well secured and in the process of collection) or when, in the opinion of management, there is a reasonable doubt as to the collectability of a loan or lease in the normal course of business. Interest income on nonaccrual loans is recognized only to the extent cash is received and the principal balance of the loan is deemed collectable.

At September 30, 2023, nonaccrual loans and leases included $77.3 million of loans and leases 90 or more days past due, $11.9 million of loans and leases 30 to 89 days past due, and $36.1 million of loans and leases current with respect to contractual payments that were placed on nonaccrual status based on management’s judgment regarding their collectability. At December 31, 2022, nonaccrual loans and leases included $70.9 million of loans and leases 90 or more days past due, $6.8 million of loans and leases 30 to 89 days past due, and $26.0 million of current loans and leases that were placed on nonaccrual status based on management’s judgment regarding their collectability.

As of September 30, 2023, our three largest loan relationships on nonaccrual status had an aggregate carrying value of $20.5 million and represented 16% of total nonaccrual loans and leases.

The following tables present the credit risk rating categories for loans and leases held for investment, net of deferred fees, by loan portfolio segment and class as of the dates indicated. Classified loans and leases are those with a credit risk rating of either substandard or doubtful.

On January 1, 2023, the Company adopted ASU 2022-02, "Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures" ("ASU 2022-02"), which eliminated the accounting guidance for troubled debt restructurings while enhancing disclosure requirements for certain loan refinancing and restructurings by creditors when a borrower is experiencing financial difficulty. This guidance was applied on a prospective basis. The following table presents our loan modifications made to borrowers experiencing financial difficulty by type of modification for the period indicated with related amortized cost balances as of the date indicated:

At September 30, 2023, there were other residential real estate loans for $8.7 million and other commercial loans for $4,000 that had been modified in the form of a term extension during the preceding three-month period and subsequently defaulted during the three months ended September 30, 2023. There were other residential real estate loans for $9.1 million and other commercial loans for $4,000 that had been modified in the form of a term extension during the preceding nine-month period and subsequently defaulted during the nine months ended September 30, 2023.

Prior to the adoption of ASU 2022-02, the Company accounted for a modification to the contractual terms of a loan that resulted in granting a concession to a borrower experiencing financial difficulties as a TDR. TDRs were a result of rate reductions, term extensions, fee concessions, transfers to foreclosed assets, discounted loan payoffs, and debt forgiveness, or a combination thereof.

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 8. Leases for information regarding operating leases where we are the lessor.

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

The allowance for loan and lease losses increased by $3.1 million in the third quarter of 2023 to $222.3 million due primarily to an increase in qualitative reserves for loans secured by office properties, offset partially by net charge-offs and lower reserves needed for lower loan balances. For additional information regarding the calculation of the allowance for loan and lease losses using the CECL methodology, including discussion of forecasts used to estimate the allowance, please see Note 1(j). Nature of Operations and Summary of Significant Accounting Policies - 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" of the Form 10-K.

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

GOODWILL AND OTHER INTANGIBLE ASSETS, NET

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 at the reporting unit level 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 the fair value of the reporting unit. An impairment loss would be recognized in an amount equal to that excess as a charge to "Noninterest expense" in the condensed consolidated statements of earnings.

The impact to banks triggered by the closure of two well-known regional banks caused a significant decline in bank stock prices in March 2023, 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 2023. We applied the market approach using an average share price of the Company's stock and a control premium to determine the estimated fair value of the reporting unit. The control premium was based upon management's judgment using historical information of control premiums for completed bank acquisitions. As a result, we recorded a goodwill impairment charge of our entire goodwill balance of $1.4 billion in the first quarter of 2023 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.

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

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.

Stock-Based Compensation

STOCKHOLDERS' EQUITY

Stock-Based Compensation

At the annual meeting of stockholders held on May 11, 2021, the Company's stockholders approved the Amended and Restated PacWest Bancorp 2017 Stock Incentive Plan (the “Amended and Restated 2017 Plan”). The Company’s Amended and Restated 2017 Plan permits stock-based compensation awards to officers, directors, employees, and consultants and will remain in effect until December 31, 2026. The Amended and Restated 2017 Plan authorizes grants of stock-based compensation instruments to issue up to 6,650,000 shares. As of September 30, 2023, there were 2,032,871 shares available for grant under the Amended and Restated 2017 Plan.

Restricted Stock

Restricted stock amortization totaled $0.3 million and $9.5 million for the three months ended September 30, 2023 and 2022 and $12.9 million and $26.1 million for the nine months ended September 30, 2023 and 2022. Such amounts are included in "Compensation expense" on the condensed consolidated statements of earnings. The amount of unrecognized compensation expense related to unvested TRSAs and PRSUs as of September 30, 2023 totaled $49.4 million.

Time-Based Restricted Stock Awards

At September 30, 2023, there were 1,380,848 shares of unvested TRSAs outstanding. TRSAs generally vest ratably over a service period of three or 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 award on the grant date and is recognized over the vesting period using the straight-line method.

Performance-Based Restricted Stock Units

At September 30, 2023, there were 656,049 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 shares underlying 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 200% of target.

Compensation expense related to PRSUs is based on the fair value of the underlying award on the grant 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 or all of the amortization is suspended, or (2) attainment of the financial metrics is improbable, in which case a portion or all 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 to up to 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 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.

Preferred Stock

At September 30, 2023, our preferred stock of $498.5 million represents 20,530,000 depositary shares (the “Depositary Shares”), each representing a 1/40th ownership interest in a share of the Company’s 7.75% fixed rate reset non-cumulative, non-convertible, perpetual preferred stock, Series A, par value $0.01 per share (the “Series A preferred stock”), with a liquidation preference of $1,000 per share of Series A preferred stock (equivalent to $25.00 per Depositary Share). The Series A preferred stock qualifies as Tier 1 capital for purposes of regulatory capital calculations. The Series A preferred stock is perpetual and has no maturity date.

Dividends on the Series A preferred stock are not cumulative or mandatory. If the Company’s Board of Directors does not declare a dividend on the Series A preferred stock in respect of a dividend period, then no dividend shall be deemed to be payable for such dividend period or be cumulative, and the Company will have no obligation to pay any dividend for that dividend period, whether or not the Board of Directors declares a dividend on the Series A preferred stock or any other class or series of its capital stock for any future dividend period. Additionally, so long as any share of Series A preferred stock remains outstanding, unless dividends on all outstanding shares of Series A preferred stock for the most recently completed dividend period have been paid in full or declared and a sum sufficient for the payment thereof has been set aside for payment, no dividend shall be declared or paid or set aside for payment and no distribution shall be declared or made or set aside for payment on the Company’s common stock.

(1)    Balance is net of unamortized issuance costs of $10.9 million and $4.8 million of accrued exit fees. Rate calculation does not include the effects of issuance costs and exit fees.

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 financing capacity with the FHLB as of September 30, 2023 of $4.3 billion, collateralized by a blanket lien on $8.5 billion of qualifying loans and $18.4 million of securities. As of September 30, 2023, there were no balances outstanding. As of December 31, 2022, the balance outstanding was $1.3 billion, which consisted of an overnight advance and two term advances with maturity dates of January 2023 and February 2023.

FRBSF Secured Line of Credit. The Bank has a secured line of credit with the FRBSF. As of September 30, 2023, the Bank had secured borrowing capacity of $6.5 billion collateralized by liens covering $6.8 billion of qualifying loans and $1.5 billion of securities. As of September 30, 2023 and December 31, 2022, there were no balances outstanding.

FRBSF Bank Term Funding Program. In March of 2023, the Bank participated in the FRBSF Bank Term Funding Program. As of September 30, 2023, the Bank had secured borrowing capacity of $4.9 billion collateralized by the par value of pledged securities totaling $4.9 billion. As of September 30, 2023, the balance outstanding was $4.9 billion consisting of two term advances maturing in March 2024.

Repurchase Agreement. In March of 2023, the Bank entered into a repurchase agreement through which it borrowed $1.4 billion that was collateralized by loans with a principal balance of $2.1 billion. In connection with this borrowing, the Bank incurred $17.9 million of issuance costs and accrued $0.4 million in exit fees. The repurchase agreement is to be repaid with collections on the underlying loans. The repurchase agreement has a term of 18 months, under which the interest rate is 8.50% for amounts outstanding during the first nine months and 8.75% for amounts outstanding during the last nine months. The Bank has the option to pay off the repurchase agreement after the first nine months. Per the terms of the agreement, a reserve account equal to 1.5% of the facility commitment amount was deposited with a third-party bank to be used for certain purposes. Any remaining funds will be returned to PacWest at the time of payoff or maturity of the facility. At September 30, 2023, the borrowing amount outstanding was $1.3 billion collateralized by loans with a principal balance of $2.0 billion.

Credit-Linked Notes. The notes were issued in five classes, each with an interest rate of SOFR plus a spread that ranges from 8.00% to 13.25%, with a weighted average spread of 10.68% at September 30, 2023. The notes are linked to the credit risk of an approximately $2.51 billion reference pool of previously purchased single-family residential mortgage loans at September 30, 2023. The notes are due June 27, 2052. Principal payments on the notes are based only on scheduled and unscheduled principal that is actually collected on these loans. The notes are reported at fair value of $123.8 million at September 30, 2023. See Note 12. Fair Value Option for additional information.

Federal Funds Arrangements with Commercial Banks. As of September 30, 2023, the Bank had unsecured lines of credit of $100.0 million in the aggregate with several correspondent banks for the purchase of overnight funds, subject to availability of funds. These lines are renewable annually and have no unused commitment fees. As of September 30, 2023 and December 31, 2022, 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 September 30, 2023, there was no balance outstanding. As of December 31, 2022, the balance outstanding was $250.0 million, which consisted of $250.0 million in overnight borrowings.

DERIVATIVES

To a limited extent, the Company utilizes interest rate swaps contracts with clients and counterparty banks for the purpose of offsetting or hedging exposures arising out of lending and borrowing transactions. The Company offers borrowers interest rate swaps under a "back-to-back" loan hedging program and offsets these "pay floating/receive fixed" contracts with borrowers with "receive fixed/ pay floating" swaps with counterparty banks. The total notional balance of these offsetting hedging contracts was $106.4 million at September 30, 2023. The Company has also hedged the interest rate risk and foreign currency risk on €25.8 million of subordinated debt utilizing a combined cross currency swap/interest rate swap, which has had the effect of hedging the foreign currency risk and fixing the Euribor-based floating rate instrument at a fixed rate of 2.76% through July 2025. The outputs from the Company's NII simulation analysis and MVE modeling reflect the impact of these interest rate/currency swaps, however, the impact is not material. During the year ended December 31, 2022 and the nine months ended September 30, 2023, there were no changes to our hedging program described above. The following table presents the U.S. dollar notional amounts and fair values of our derivative instruments included in the condensed consolidated balance sheets as of the dates indicated:

COMMITMENTS AND CONTINGENCIES

The following table presents a summary of commitments described below as of the dates indicated:

	September 30,		December 31,
	2023		2022
	(In thousands)
Loan commitments to extend credit	$	5,289,221	$	11,110,264
Standby letters of credit	265,191		320,886
Total	$	5,554,412	$	11,431,150

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 condensed 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. The estimated exposure to loss from these commitments is included in the reserve for unfunded loan commitments, which amounted to $29.6 million at September 30, 2023 and $91.1 million at December 31, 2022.

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.

In addition, we 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 September 30, 2023 and December 31, 2022, we had commitments to contribute capital to these entities totaling $76.6 million and $76.9 million.

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:

	September 30, 2023
	(In thousands)
Period ending December 31,
2023	$	41,422
2024	35,176
Total	$	76,598

Legal Matters

In the ordinary course of our business, the Company is party to various legal actions, which we believe are incidental to the operation of our business. The outcome of such legal actions and the timing of ultimate resolution are inherently difficult to predict. In the opinion of management, based upon currently available information, any resulting liability, in addition to amounts already accrued, 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 MEASUREMENTS

The Company uses fair value to measure certain assets and liabilities on a recurring basis, primarily securities available-for-sale, derivatives, and certain debt liabilities. 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.

For information regarding the valuation methodologies used to measure our assets recorded at fair value (under ASC Topic 820), and for estimating fair value for financial instruments not recorded at fair value (under ASC Topic 825, as amended by ASU 2016-01 and ASU 2018-03), see Note 1. Nature of Operations and Summary of Significant Accounting Policies and Note 15. Fair Value Measurements to the Consolidated Financial Statements of the Company's Form 10-K.

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 September 30, 2023, the fair value of these investments was $77.8 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:

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 September 30, 2023, the amounts that will actually be realized or paid at settlement or maturity of the instruments could be significantly different.

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.

Nature of Operations and Summary of Significant Accounting Policies and Note 15. Fair Value Measurements to the Consolidated Financial Statements of the Company's Form 10-K.

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 September 30, 2023, the amounts that will actually be realized or paid at settlement or maturity of the instruments could be significantly different.

Stockholders' Equity

Share-Based Payment Arrangement [Abstract]

Stock-Based Compensation

STOCKHOLDERS' EQUITY

Stock-Based Compensation

At the annual meeting of stockholders held on May 11, 2021, the Company's stockholders approved the Amended and Restated PacWest Bancorp 2017 Stock Incentive Plan (the “Amended and Restated 2017 Plan”). The Company’s Amended and Restated 2017 Plan permits stock-based compensation awards to officers, directors, employees, and consultants and will remain in effect until December 31, 2026. The Amended and Restated 2017 Plan authorizes grants of stock-based compensation instruments to issue up to 6,650,000 shares. As of September 30, 2023, there were 2,032,871 shares available for grant under the Amended and Restated 2017 Plan.

Restricted Stock

Restricted stock amortization totaled $0.3 million and $9.5 million for the three months ended September 30, 2023 and 2022 and $12.9 million and $26.1 million for the nine months ended September 30, 2023 and 2022. Such amounts are included in "Compensation expense" on the condensed consolidated statements of earnings. The amount of unrecognized compensation expense related to unvested TRSAs and PRSUs as of September 30, 2023 totaled $49.4 million.

Time-Based Restricted Stock Awards

At September 30, 2023, there were 1,380,848 shares of unvested TRSAs outstanding. TRSAs generally vest ratably over a service period of three or 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 award on the grant date and is recognized over the vesting period using the straight-line method.

Performance-Based Restricted Stock Units

At September 30, 2023, there were 656,049 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 shares underlying 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 200% of target.

Compensation expense related to PRSUs is based on the fair value of the underlying award on the grant 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 or all of the amortization is suspended, or (2) attainment of the financial metrics is improbable, in which case a portion or all 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 to up to 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 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.

Preferred Stock

At September 30, 2023, our preferred stock of $498.5 million represents 20,530,000 depositary shares (the “Depositary Shares”), each representing a 1/40th ownership interest in a share of the Company’s 7.75% fixed rate reset non-cumulative, non-convertible, perpetual preferred stock, Series A, par value $0.01 per share (the “Series A preferred stock”), with a liquidation preference of $1,000 per share of Series A preferred stock (equivalent to $25.00 per Depositary Share). The Series A preferred stock qualifies as Tier 1 capital for purposes of regulatory capital calculations. The Series A preferred stock is perpetual and has no maturity date.

Dividends on the Series A preferred stock are not cumulative or mandatory. If the Company’s Board of Directors does not declare a dividend on the Series A preferred stock in respect of a dividend period, then no dividend shall be deemed to be payable for such dividend period or be cumulative, and the Company will have no obligation to pay any dividend for that dividend period, whether or not the Board of Directors declares a dividend on the Series A preferred stock or any other class or series of its capital stock for any future dividend period. Additionally, so long as any share of Series A preferred stock remains outstanding, unless dividends on all outstanding shares of Series A preferred stock for the most recently completed dividend period have been paid in full or declared and a sum sufficient for the payment thereof has been set aside for payment, no dividend shall be declared or paid or set aside for payment and no distribution shall be declared or made or set aside for payment on the Company’s common stock.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Significant Accounting Policies

Significant Accounting Policies

Our accounting policies are described in Note 1. Nature of Operations and Summary of Significant Accounting Policies, of our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2022 as filed with the Securities and Exchange Commission ("Form 10-K"). Updates to our significant accounting policies described below reflect the impact of the adoption of ASU 2022-02, "Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures ("ASU 2022-02")," specifically the amendment to troubled debt restructurings, and organizational changes which resulted in changes to our reportable operating segments.

Loan Modifications to Borrowers Experiencing Financial Difficulty

Loan modifications made to borrowers experiencing financial difficulty constitute modifications of receivables in the form of principal forgiveness, an interest rate reduction, an other than-insignificant payment delay, or a term extension. ASU 2022-02 eliminated the concept of troubled debt restructurings and introduced broader modification reporting requirements. Previously, troubled debt restructurings included any type of modification that included a below market concession which was granted both to a borrower in financial difficulty and as a result of financial difficulty. Loan modifications made to borrowers experiencing financial difficulty no longer consider whether a market concession has been granted, as was required with troubled debt restructurings, but rather includes as modifications within the four listed reportable modification types to a borrower deemed to be experiencing financial difficulty. An assessment of whether a borrower is experiencing financial difficulty is made on the date of the modification. Loans reported in this classification have a rating of substandard or worse, and may include both accruing and nonaccruing loans. Loans are assessed to determine whether the modification constitutes a new loan or a continuation of the existing loan. Depending on the terms of the modification and nature of the borrower, this may result in a downgrade or placing a loan on nonaccrual status, which in turn would impact the loan's classification within the ALLL. Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses because of the measurement methodologies used to estimate the allowance, a change to the allowance for credit losses is generally not recorded upon modification.

Business SegmentsWe regularly assess our strategic plans, operations, reporting structures and financial information provided to management to identify our reportable segments. Civic, a lending subsidiary we acquired in February 2021, has historically been identified as an operating segment. In the fourth quarter of 2022, Civic met a quantitative threshold which required it to be disclosed as a reportable operating segment. Therefore, we had two reportable operating segments as of December 31, 2022: Commercial Banking and Civic, and a third segment, Other, which was used for inter-segment eliminations. In the first quarter of 2023, we began a restructuring of Civic which included removing most of Civic's top management and transferring day-to-day management of most of Civic's operating functions to managers at the Bank. Due to the restructuring of Civic, discrete financial information is no longer prepared. Our management reporting captures the direct expenses of Civic, however, none of the expenses now being incurred to manage Civic are being directly charged or allocated to Civic. Therefore, it is no longer feasible to produce meaningful, separate full financial statements, and thus, discrete financial information for Civic is no longer prepared or distributed to our chief operating decision maker. Thus, Civic no longer meets the criteria to be considered a reportable operating segment as of March 31, 2023. We sold the Civic business in the second quarter of 2023, and we are retaining and servicing the Civic loans on our balance sheet. At September 30, 2023, June 30, 2023, and March 31, 2023, we operated as one reportable segment - Commercial Banking.

Recently Issued Accounting Standards

Accounting Standards Adopted in 2023

Effective January 1, 2023, we completed the adoption of ASU 2022-02, “Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures," by eliminating the accounting guidance for TDRs by creditors, in ASC 310-40, "Receivables – Troubled Debt Restructurings by Creditors," while enhancing disclosure requirements for restructurings involving borrowers that are experiencing financial difficulty. The Company updated its disclosures in Note 4. Loans and Leases to present information regarding loan modifications to borrowers experiencing financial difficulty. There was no transition adjustment recorded to retained earnings upon adoption. The adoption of this amendment did not have a material impact on the Company’s condensed consolidated financial statements.

RECENTLY ISSUED ACCOUNTING STANDARDS

		Effective	Effect on the Financial Statements
Standard	Description	Date	or Other Significant Matters
ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions	This standard clarifies that a contractual sale restriction is not considered in measuring an equity security at fair value. The standard also clarifies that an entity cannot recognize a contractual sale restriction as a separate unit of account, such as a contra-asset or liability. The standard requires new disclosures for all entities with equity securities subject to contractual sales restrictions. Additionally, early adoption is permitted.	January 1, 2024	The Company does not take into account contractual sale restrictions in determining the fair value of its equity securities. The Company expects that this standard will not have a material impact on its consolidated financial statements.

ASU 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Issues Task Force)	This standard expands the proportional amortization method to account for investments in all tax credit structures. That accounting method was previously allowed only for low-income housing tax credit ("LIHTC") investments, but now is available, by election, to all community development tax credit investment reporting that meets five conditions. Under the new guidance, reporting entities can make accounting policy elections on a tax-credit-program-by-tax-credit-program basis, rather than for individual investments or at the reporting entity level. Additionally, early adoption is permitted.	January 1, 2024	The Company is evaluating the impact of this standard on its consolidated financial statements.

The amendments in this standard should be applied prospectively. Early adoption is prohibited.	The effective date for each amendment will be the date on which the SEC's removal of the related disclosure from Regulation S-X or Regulation S-K becomes effective.	The Company is evaluating the impact of this standard on its consolidated financial statements.

Basis of Presentation    Our interim condensed consolidated financial statements are prepared in accordance with U.S. GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, certain disclosures accompanying annual consolidated financial statements are omitted. In the opinion of management, all 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 for the interim periods, have been included. The current period's results of operations are not necessarily indicative of the results that ultimately may be achieved for the year. The interim condensed consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Form 10-K.

Use of Estimates

Use of EstimatesWe have made a number of estimates and assumptions related to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period to prepare these condensed consolidated financial statements in conformity with U.S. GAAP. 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 intangible assets, the fair value of loans held for sale, and the realization of deferred tax assets. These estimates may be adjusted as more current information becomes available, and any adjustment may be significant.

Reclassifications

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 certain of our loan portfolio classes and subclasses to better reflect and report our lending. We made the following changes: (1) moved the "Multi-family" loan subclass from the residential real estate mortgage class into its own loan class; (2) moved the "Construction - renovation" loan subclass from the residential real estate construction and land loan class to the residential real estate mortgage class and renamed it "Residential renovation;" and (3) renamed the residential real estate mortgage loan class as "Other residential." All of the loan and allowance tables, both current period and prior periods, reflect these changes and realignment.

Fair Value Measures and Disclosures (Policies)	9 Months Ended
	Sep. 30, 2023
Fair Value Disclosures [Abstract]
Fair Value Election	FAIR VALUE OPTIONThe Company may elect to report financial instruments and certain other items at fair value on an instrument-by-instrument basis with changes in fair value reported in earnings. The election is made upon the initial recognition of an eligible financial asset, financial liability, or firm commitment or when certain specified reconsideration events occur. The fair value election may not otherwise be revoked once an election is made. The changes in fair value are recorded in "Noninterest income" on the condensed consolidated statements of earnings. However, movements in debt valuation adjustments are reported as a component of "Accumulated other comprehensive (loss) income" on the condensed consolidated balance sheets. Debt valuation adjustments represent the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk. Fair Value Option for Certain Debt LiabilitiesThe Company has elected the fair value option for the credit-linked notes issued in September 2022. The Company elected the fair value option because these exposures are considered to be structured notes, which are financial instruments that contain embedded derivatives. The notes are linked to the credit risk of an approximately $2.51 billion reference pool of previously purchased single-family residential mortgage loans. The principal balance of the credit-linked notes was $126.1 million at September 30, 2023. The carrying value of the credit-linked notes at September 30, 2023 was the estimated fair value of $123.8 million.

Fair Value Measurement, Policy

FAIR VALUE MEASUREMENTS

The Company uses fair value to measure certain assets and liabilities on a recurring basis, primarily securities available-for-sale, derivatives, and certain debt liabilities. 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.

For information regarding the valuation methodologies used to measure our assets recorded at fair value (under ASC Topic 820), and for estimating fair value for financial instruments not recorded at fair value (under ASC Topic 825, as amended by ASU 2016-01 and ASU 2018-03), see Note 1. Nature of Operations and Summary of Significant Accounting Policies and Note 15. Fair Value Measurements to the Consolidated Financial Statements of the Company's Form 10-K.

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 September 30, 2023, the fair value of these investments was $77.8 million.
