MERCURY GENERAL CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)

1. General

Consolidation and Basis of Presentation
The interim consolidated financial statements include the accounts of Mercury General Corporation and its subsidiaries (referred to herein collectively as the “Company”). For the list of the Company’s subsidiaries, see Note 1. Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. These interim financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”), which differ in some respects from those filed in reports to insurance regulatory authorities. The financial data of the Company included herein are unaudited. In the opinion of management, all material adjustments of a normal recurring nature have been made to present fairly the Company’s financial position at September 30, 2024 and the results of operations and cash flows for the periods presented. All intercompany transactions and balances have been eliminated.

Certain financial information that is normally included in annual financial statements prepared in accordance with GAAP, but that is not required for interim reporting purposes, has been omitted from the accompanying interim consolidated financial statements and related notes. Readers are urged to review the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 for more complete descriptions and discussions. Operating results and cash flows for the nine months ended September 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024.

Certain prior period amounts have been reclassified to conform to the current period presentation.

Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates require the Company to apply complex assumptions and judgments, and often the Company must make estimates about the effects of matters that are inherently uncertain and will likely change in subsequent periods. The most significant assumptions in the preparation of these consolidated financial statements relate to reserves for losses and loss adjustment expenses ("LAE"). Actual results could differ from those estimates. See Note 1. Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.
Earnings (Loss) per Share
There were no potentially dilutive securities with anti-dilutive effect for the three and nine months ended September 30, 2024. Potentially dilutive securities representing 17,500 shares of common stock were excluded from the computation of diluted loss per share for the three and nine months ended September 30, 2023, because their effect would have been anti-dilutive.
Dividends per Share
The Company declared and paid a dividend per share of $0.3175 during each of the three-month periods ended September 30, 2024 and 2023, and dividends per share of $0.9525 during each of the nine-month periods ended September 30, 2024 and 2023.
Deferred Policy Acquisition Costs
Deferred policy acquisition costs consist of commissions paid to outside agents, premium taxes, salaries, and certain other underwriting costs that are incremental or directly related to the successful acquisition of new and renewal insurance contracts and are amortized over the life of the related policy in proportion to premiums earned. Deferred policy acquisition costs are limited to the amount that will remain after deducting from unearned premiums and anticipated investment income, the estimated losses and loss adjustment expenses, and the servicing costs that will be incurred as premiums are earned. The Company’s deferred policy acquisition costs are further limited by excluding those costs not directly related to the successful acquisition of insurance contracts. Deferred policy acquisition cost amortization was $230.3 million and $181.6 million for the three months ended September 30, 2024 and 2023, respectively, and $630.0 million and $518.8 million for the nine months ended September 30, 2024 and 2023, respectively. The Company does not defer advertising expenditures but expenses them as
7
incurred. The Company recorded net advertising expense of approximately $6.5 million and $2.4 million for the three months ended September 30, 2024 and 2023, respectively, and $13.8 million and $6.6 million for the nine months ended September 30, 2024 and 2023, respectively.

Fixed Assets

An office building located in Oklahoma City, Oklahoma was initially classified as a property held for sale at April 30, 2024, and $3.4 million of the property held for sale, which represented the estimated fair value of the property less the estimated costs to sell, as adjusted for changes in those estimates after the initial held-for-sale classification, was included in other assets in the Company's consolidated balance sheets until completion of the sale. A loss of $0.3 million and $1.0 million recognized as a result of the held-for-sale classification was included in other revenues in the Company's consolidated statements of operations for the three and nine months ended September 30, 2024, respectively. The Company completed the sale of this property in September 2024 for a total sale price of $3.6 million, and recognized an additional loss of $0.1 million at closing of the sale, which is included in other revenues in the Company's consolidated statements of operations for the three and nine months ended September 30, 2024. In connection with the sale of the property, the Company entered into a lease agreement whereby the Company leased 5,000 square feet of office space, or approximately 5% of the total space of the property sold, from the new owner of the property. The lease commenced in September 2024 and expires at December 31, 2024, and the monthly base rent is approximately $8,000.

The Company completed the sale of another office building located in Brea, California in September 2024 for a total sale price of $31.5 million, and recognized a gain of $20.3 million associated with the sale, which is included in other revenues in the Company's consolidated statements of operations for the three and nine months ended September 30, 2024. $21.4 million of the total sale price was received in the form of a promissory note. $9.3 million of the total sale price, after settlement of selling expenses and outstanding amounts due on the property, was received in cash. Only the cash received on the sale of the property is included in the Company's consolidated statements of cash flows for the nine months ended September 30, 2024. The note receivable is secured by the property sold and bears interest at an annual rate of 7.0%. The term of the note receivable is 4 years and interest is paid in quarterly installments. This office building was initially classified as a property held for sale at September 30, 2023, and $10.5 million of the property held for sale, which represented the carrying amount of the property, was included in other assets in the Company's consolidated balance sheets until completion of the sale.

An office building located in Folsom, California was classified as a property held for sale at June 30, 2024, and $10.0 million of the property held for sale, which represented the estimated fair value of the property less the estimated costs to sell, was included in other assets in the Company's consolidated balance sheets at September 30, 2024. A loss of $5.4 million recognized as a result of the held-for-sale classification was included in other revenues in the Company's consolidated statements of operations for the nine months ended September 30, 2024.

In addition, a parcel of land located in Rancho Cucamonga, California was classified as a property held for sale at June 30, 2024, and $1.7 million of the property held for sale, which represented the carrying amount of the property, was included in other assets in the Company's consolidated balance sheets at September 30, 2024.

The Company is actively engaged in selling these real estate properties as most of its employees currently work from home and these properties are being used on a limited basis.

Reinsurance

Unearned premiums and loss and loss adjustment expense reserves are stated in the accompanying consolidated financial statements before deductions for ceded reinsurance. Unearned premiums and loss and loss adjustment expense reserves that are ceded to reinsurers are carried in other assets and reinsurance recoverables, respectively, in the Company's consolidated balance sheets. Earned premiums and losses and loss adjustment expenses are stated net of deductions for ceded reinsurance.
The Company is the assuming reinsurer under a Catastrophe Participation Reinsurance Contract (the "Contract") effective through December 31, 2025. The Company reimburses up to $30 million in losses for a proportional share of a portfolio of catastrophe losses under the Contract, to the extent the actual loss ratio exceeds the threshold loss ratio of 73.5%. If the actual loss ratio is less than the threshold loss ratio, the Company is eligible to receive a certain portion of the underwriting profit.

The Company is party to a Catastrophe Reinsurance Treaty (the "Treaty") covering a wide range of perils that is effective through June 30, 2025. The Treaty provides $1,290 million of coverage on a per occurrence basis after covered catastrophe losses exceed the $150 million Company retention limit. The Treaty specifically excludes coverage for any Florida business and for California earthquake losses on fixed property policies, such as homeowners, but does cover losses from fires following an
8
earthquake. The Treaty provides for one full reinstatement of coverage limits with a minor exception at a certain upper layer of coverage, and includes some additional minor territorial and coverage restrictions.

The effect of reinsurance on property and casualty premiums written and earned was as follows:

     Net$1,313,282 $1,082,979 $3,701,347 $3,107,812 

The Company recognized ceded premiums earned of approximately $42.4 million and $30.9 million for the three months ended September 30, 2024 and 2023, respectively, and $104.9 million and $78.1 million for the nine months ended September 30, 2024 and 2023, respectively, which are included in net premiums earned in its consolidated statements of operations. The Company recognized ceded losses and loss adjustment expenses of approximately $(1.5) million and $(0.3) million for the three months ended September 30, 2024 and 2023, respectively, and $(2.5) million and $3.8 million for the nine months ended September 30, 2024 and 2023, respectively, which are included in losses and loss adjustment expenses in its consolidated statements of operations.

The Company's insurance subsidiaries, as primary insurers, are required to pay losses to the extent reinsurers are unable to discharge their obligations under the reinsurance agreements.

Revenue from Contracts with Customers (Topic 606)

The Company's revenue from contracts with customers is commission income earned from third-party insurers by its 100% owned insurance agencies, which amounted to approximately $6.4 million and $5.2 million, with related expenses of $3.2 million and $2.7 million, for the three months ended September 30, 2024 and 2023, respectively, and $18.0 million and $15.0 million, with related expenses of $9.6 million and $8.2 million, for the nine months ended September 30, 2024 and 2023, respectively. All of the commission income, net of related expenses, is included in other revenues in the Company's consolidated statements of operations, and in other income of the Property and Casualty business segment in the Company's segment reporting (see Note 13. Segment Information).

As of September 30, 2024 and December 31, 2023, the Company had no contract assets and contract liabilities, and no remaining performance obligations associated with unrecognized revenues.

Allowance for Credit Losses

Financial Instruments - Credit Losses (Topic 326) uses the "expected loss" methodology for recognizing credit losses for financial assets that are not accounted for at fair value through net income. The Company's investment portfolio, excluding accrued investment income, was not affected by Topic 326 as it applies the fair value option to all of its investments. The estimated allowance amounts for credit losses at September 30, 2024 and December 31, 2023 primarily related to premiums receivable.

Premiums Receivable

The majority of the Company's premiums receivable are short-term in nature and are due within a year, consistent with the policy term of its insurance policies sold. Generally, premiums are collected prior to providing risk coverage, minimizing the Company's exposure to credit risk. In estimating an allowance for uncollectible premiums receivable, the Company assesses
9
customer balances and write-offs by state, line of business, and the year the premiums were written. The estimated allowance is based on historical write-off percentages adjusted for the effects of current trends and reasonable and supportable forecasts, as well as expected recoveries of amounts written off.

The following table presents a summary of changes in allowance for credit losses on premiums receivable:
 Three Months Ended September 30,Nine Months Ended September 30,

 (Amounts in thousands)

Recoveries during the period of amounts previously written off 245 126 631 405 
Ending balance $6,100 $5,200 $6,100 $5,200 

Accrued Interest Receivables

The Company made certain accounting policy elections for its accrued interest receivables allowed under Topic 326: a) an election to present accrued interest receivable balances separately from the associated financial assets on the balance sheet, and b) an election not to measure an allowance for credit losses on accrued interest receivable amounts and instead write off uncollectible accrued interest amounts in a timely manner by reversing interest income. The Company's accrued interest receivable balances are included in accrued investment income receivable in its consolidated balance sheets. There were no accrued interest receivable amounts considered uncollectible or written off during the nine months ended September 30, 2024 and 2023.

2. Recently Issued Accounting Standards

In March 2024, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) 2024-01, "Compensation-Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards." ASU 2024-01 is intended to improve GAAP by adding an illustrative example that includes four fact patterns to demonstrate how an entity should apply the scope guidance in paragraph 718-10-15-3 to determine whether a profits interest award should be accounted for in accordance with Topic 718. The fact patterns in the illustrative example focus on the scope conditions in paragraph 718-10-15-3. The illustrative example is intended to reduce (1) complexity in determining whether a profits interest award is subject to the guidance in Topic 718 and (2) existing diversity in practice. ASU 2024-01 will be effective for the Company in the annual and interim periods beginning January 1, 2025, though early adoption is permitted. The Company is currently evaluating the impact of this ASU on its consolidated financial statements and related disclosures.

In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures." ASU 2023-09 is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in ASU 2023-09 address investor requests for enhanced income tax information primarily through changes to the rate reconciliation and income taxes paid information. ASU 2023-09 will be effective for the Company in the annual period beginning January 1, 2025, though early adoption is permitted. The Company is evaluating the presentational effect that ASU 2023-09 will have on its consolidated financial statements and expects presentation changes to its note on income taxes.

In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures." The amendments in ASU 2023-07 improve financial reporting by requiring disclosure of incremental segment information, including significant segment expenses, on an annual and interim basis for all public entities to enable investors to develop more useful financial analyses. Currently, Topic 280 requires that a public entity disclose certain information about its reportable segments. For example, a public entity is required to report a measure of segment profit or loss that the Chief Operating Decision Maker (“CODM”) uses to assess segment performance and make decisions about allocating resources. Topic 280 also requires other specified segment information, such as depreciation, amortization and depletion expense amounts, to be disclosed under certain circumstances. The amendments in ASU 2023-07 do not change or remove those disclosure requirements. The amendments in ASU 2023-07 also do not change how a public entity identifies its operating segments, aggregates those operating segments, or applies the quantitative thresholds to determine its reportable segments. The amendments in ASU 2023-07 are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of this
10
ASU on its consolidated financial statements and related disclosures.

In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." ASU 2020-04 provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this ASU apply only to contracts, hedging relationships, and other transactions that reference LIBOR or other interbank offered rates expected to be discontinued because of reference rate reform. ASU 2020-04 was effective for all entities as of March 12, 2020 through December 31, 2022. In December 2022, the FASB issued ASU 2022-06, "Reference Rate Reform (Topic 848), Deferral of the Sunset Date of Topic 848," which defers the sunset date of Topic 848 from December 31, 2022 to December 31, 2024. The Company does not expect any material impact on its consolidated financial statements and related disclosures resulting from applying these ASUs.

3. Financial Instruments

Financial instruments recorded in the consolidated balance sheets include investments, note receivable, other receivables, options sold, accounts payable, and unsecured notes payable. Due to their short-term maturities, the carrying values of other receivables and accounts payable approximate their fair values. All investments are carried at fair value in the consolidated balance sheets.

The cost of investments sold is determined on a first-in and first-out method and realized gains and losses are included in net realized investment gains or losses in the Company's consolidated statements of operations.

In the normal course of investing activities, the Company either forms or enters into relationships with variable interest entities ("VIEs"). A VIE is an entity that either has investors that lack certain essential characteristics of a controlling financial interest, such as simple majority kick-out rights, or lacks sufficient funds to finance its own activities without financial support provided by other entities. The Company performs ongoing qualitative assessments of the VIEs to determine whether the Company has a controlling financial interest in the VIE and therefore is the primary beneficiary. The Company is deemed to have a controlling financial interest when it has both the ability to direct the activities that most significantly impact the economic performance of the VIE and the obligation to absorb losses or right to receive benefits from the VIE that could potentially be significant to the VIE. Based on the Company's assessment, if it determines it is the primary beneficiary, the Company consolidates the VIE in its consolidated financial statements.

From time to time, the Company forms special purpose investment vehicles to facilitate its investment activities involving derivative instruments such as total return swaps, or limited partnerships such as private equity funds. These special purpose investment vehicles are consolidated VIEs as the Company has determined it is the primary beneficiary of such VIEs. Creditors have no recourse against the Company in the event of default by these VIEs. The Company had no implied or unfunded commitments to these VIEs at September 30, 2024 and December 31, 2023. The Company's financial or other support provided to these VIEs and its loss exposure are limited to its collateral and original investment.

The Company invests, directly or indirectly through its consolidated VIEs, in limited partnerships or limited liability companies such as private equity funds. These investments are non-consolidated VIEs as the Company has determined it is not the primary beneficiary of such VIEs. The Company's maximum exposure to loss with respect to these VIEs is limited to the total carrying value that is included in equity securities in the Company's consolidated balance sheets. At each of September 30,
11
2024 and December 31, 2023, the Company had approximately $8 million in unfunded commitments to these VIEs.

Notes Receivable

In September 2024, the Company completed the sale of an office building located in Brea, California for a total sale price of $31.5 million. $21.4 million of the total sale price was received in the form of a promissory note. The note receivable is secured by the property sold, and bears interest at an annual rate of 7.0%. The term of the note receivable is four years and interest is paid in quarterly installments.

In March 2023, the Company completed the sale of an office building located in Clearwater, Florida, for a total sale price of approximately $19.6 million. $9.8 million of the total sale price was received in the form of a promissory note. The note receivable is secured by the property sold, and bears interest at an annual rate of 7.0% for the first two years, with an adjustment to the greater of 7.0% or the rate on a one-year U.S. Treasury Bill at the two-year anniversary for the remainder of the term. The term of the note receivable is four years and interest is paid in monthly installments.

Interest earned on the notes receivable is recognized in other revenues in the Company's consolidated statements of operations. The Company elected to apply the fair value option to the notes receivable at the time they were first recognized. The fair values of the notes receivable are included in other assets in the Company's consolidated balance sheets, while the changes in fair value of the notes receivable are included in net realized investment gains or losses in the Company's consolidated statements of operations.

Options Sold
The Company writes covered call options through listed and over-the-counter exchanges. When the Company writes an option, an amount equal to the premium received by the Company is recorded as a liability and is subsequently adjusted to the current fair value of the option written. Premiums received from writing options that expire unexercised are treated by the Company as realized gains from investments on the expiration date. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security or currency in determining whether the Company has realized a gain or loss. The Company, as writer of an option, bears the market risk of an unfavorable change in the price of the security underlying the written option. Liabilities for covered call options are included in other liabilities in the Company's consolidated balance sheets.

Notes Payable
The fair values of the Company’s publicly traded $375 million unsecured notes at September 30, 2024 and December 31, 2023 and its $200 million drawn under the unsecured credit facility at September 30, 2024 and December 31, 2023 were obtained from a third party pricing service.

For additional disclosures regarding methods and assumptions used in estimating fair values, see Note 5. Fair Value Measurements.

4. Fair Value Option

The Company applies the fair value option to all fixed maturity and equity investment securities, short-term investments, and notes receivable. The primary reasons for electing the fair value option were simplification and cost-benefit considerations as well as the expansion of the use of fair value measurement by the Company consistent with the long-term measurement objectives of the FASB for accounting for financial instruments.

Gains or losses due to changes in fair value of financial instruments measured at fair value pursuant to application of the fair value option are included in net realized investment gains or losses in the Company’s consolidated statements of operations.

5. Fair Value Measurements

The Company employs a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date using the exit price. Accordingly, when market observable data are not readily available, the Company’s own assumptions are used to reflect those that market participants would be presumed to use in pricing the asset or liability at the measurement date.

Assets and liabilities recorded at fair value on the consolidated balance sheets are categorized based on the level of judgment associated with inputs used to measure their fair values and the level of market price observability, as follows:

Level 1Unadjusted quoted prices are available in active markets for identical assets or liabilities as of the reporting date.
Level 2
Pricing inputs are other than quoted prices in active markets, which are based on the following:
 
•     Quoted prices for similar assets or liabilities in active markets;
 
•     Quoted prices for identical or similar assets or liabilities in non-active markets; or
 
•     Either directly or indirectly observable inputs as of the reporting date.
Level 3Pricing inputs are unobservable and significant to the overall fair value measurement, and the determination of fair value requires significant management judgment or estimation.

In certain cases, inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. Thus, a Level 3 fair value measurement may include inputs that are observable (Level 1 or Level 2) and unobservable (Level 3). The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and consideration of factors specific to the asset or liability.

The Company uses prices and inputs that are current as of the measurement date, including during periods of market disruption. In periods of market disruption, the ability to observe prices and inputs may be reduced for many instruments. This condition could cause an instrument to be reclassified from Level 1 to Level 2, or from Level 2 to Level 3. The Company recognizes transfers between levels at either the actual date of the event or a change in circumstances that caused the transfer.

Summary of Significant Valuation Techniques for Financial Assets and Financial Liabilities
The Company’s fair value measurements are based on the market approach, which utilizes market transaction data for the same or similar instruments. The Company obtained unadjusted fair values on 98.5% of its investment portfolio at fair value from an independent pricing service at September 30, 2024.

Level 1 measurements - Fair values of financial assets and financial liabilities are obtained from an independent pricing service, and are based on unadjusted quoted prices for identical assets or liabilities in active markets. Additional pricing services and closing exchange values are used as a comparison to ensure that reasonable fair values are used in pricing the investment portfolio.
U.S. government bonds and agencies /Short-term bonds: Valued using unadjusted quoted market prices for identical assets in
13
active markets.
Common stock: Comprised of actively traded, exchange listed U.S. and international equity securities and valued based on unadjusted quoted prices for identical assets in active markets.
Money market instruments: Valued based on unadjusted quoted prices for identical assets in active markets.
Options sold: Comprised of free-standing exchange listed derivatives that are actively traded and valued based on unadjusted quoted prices for identical instruments in active markets.
Level 2 measurements - Fair values of financial assets and financial liabilities are obtained from an independent pricing service or outside brokers, and are based on prices for similar assets or liabilities in active markets or valuation models whose inputs are observable, directly or indirectly, for substantially the full term of the asset or liability. Additional pricing services are used as a comparison to ensure reliable fair values are used in pricing the investment portfolio.
Municipal securities: Valued based on models or matrices using inputs such as quoted prices for identical or similar assets in active markets.
Mortgage-backed securities: Comprised of securities that are collateralized by residential and commercial mortgage loans valued based on models or matrices using multiple observable inputs, such as benchmark yields, reported trades and broker/dealer quotes, for identical or similar assets in active markets. The Company had holdings of $28.2 million and $33.0 million at fair value in commercial mortgage-backed securities at September 30, 2024 and December 31, 2023, respectively.

Corporate securities/Short-term bonds: Valued based on a multi-dimensional model using multiple observable inputs, such as benchmark yields, reported trades, broker/dealer quotes and issue spreads, for identical or similar assets in active markets.
Non-redeemable preferred stock: Valued based on observable inputs, such as underlying and common stock of same issuer and appropriate spread over a comparable U.S. Treasury security, for identical or similar assets in active markets.
Collateralized loan obligations ("CLOs"): Valued based on underlying debt instruments and the appropriate benchmark spread for similar assets in active markets.
Other asset-backed securities: Comprised of securities that are collateralized by non-mortgage assets, such as automobile loans, valued based on models or matrices using multiple observable inputs, such as benchmark yields, reported trades and broker/dealer quotes, for identical or similar assets in active markets.
Notes receivable: Valued based on observable inputs, such as benchmark yields, and considering any premium or discount for the differential between the stated interest rate and market interest rates, based on quoted market prices of similar instruments.
Level 3 measurements - Fair values of financial assets and financial liabilities are based on inputs that are both unobservable and significant to the overall fair value measurement, including any items in which the evaluated prices obtained elsewhere are deemed to be of a distressed trading level. At September 30, 2024 and December 31, 2023, the Company did not have any financial assets or financial liabilities based on Level 3 measurements.
Fair value measurement using NAV practical expedient - The fair value of the Company's investment in private equity funds measured at net asset value ("NAV") is determined using NAV as advised by the external fund managers and the third party administrators. The NAV of the Company's limited partnership or limited liability company interest in such a fund is based on the manager's and the administrator's valuation of the underlying holdings in accordance with the fund's governing documents and GAAP. In accordance with applicable accounting guidance, private equity funds measured at fair value using the NAV practical expedient are not classified in the fair value hierarchy. At September 30, 2024, the Company had capital invested in four such funds: the strategy of three such funds with a combined fair value of approximately $85.5 million at September 30, 2024 is to provide current income to investors by investing mainly in secured loans, CLOs or CLO issuers (including CLO equity and CLO mezzanine tranches), and equity interests in vehicles established to purchase and warehouse loans; the strategy of the other such fund with a fair value of approximately $3.7 million at September 30, 2024 is to achieve long-term capital appreciation through privately-negotiated venture capital investments in seed- and early-stage portfolio companies with technology-enabled business models. The Company had approximately $8 million in unfunded commitments at September 30, 2024 with respect to the private equity funds measured at NAV. The underlying assets of the funds are expected to be liquidated over the period of approximately one year to eight years from September 30, 2024. In addition, the Company does not have the ability to redeem or withdraw from the funds, or to sell, assign, pledge or transfer its investment, without the consent from the General Partner or Managers of the funds. The Company will receive distributions based on the liquidation of the underlying assets and the interest proceeds from the underlying assets for all the funds.

The Company’s financial instruments at fair value are reflected in the consolidated balance sheets on a trade-date basis. Related unrealized gains or losses are recognized in net realized investment gains or losses in the consolidated statements of operations. Fair value measurements are not adjusted for transaction costs.

The following tables present information about the Company’s assets and liabilities measured at fair value on a recurring basis, and indicate the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair values:

Unsecured Notes
The fair value of the Company’s publicly traded $375 million unsecured notes at September 30, 2024 and December 31, 2023 was based on the spreads above the risk-free yield curve. These spreads are generally obtained from the new issue market, secondary trading and broker-dealer quotes. See Note 11. Notes Payable for additional information on unsecured notes.

Unsecured Credit Facility
The fair values of the Company's $200 million drawn under the unsecured credit facility at September 30, 2024 and December 31, 2023 were based on the unadjusted quoted price for similar notes in active markets. See Note 11. Notes Payable for additional information on the unsecured credit facility.

6. Derivative Financial Instruments

The Company is exposed to certain risks relating to its ongoing business operations. The primary risk managed by using derivative instruments is equity price risk. Equity contracts (options sold) on various equity securities are intended to manage the price risk associated with forecasted purchases or sales of such securities. From time to time, the Company also enters into derivative contracts to enhance returns on its investment portfolio.
The following tables present the location and amounts of derivative fair values in the consolidated balance sheets and derivative gains or losses in the consolidated statements of operations:

Most options sold consist of covered calls. The Company writes covered calls on underlying equity positions held as an enhanced income strategy that is permitted for the Company’s insurance subsidiaries under statutory regulations. The Company manages the risk associated with covered calls through strict capital limitations and asset diversification throughout various industries. See Note 5. Fair Value Measurements for additional disclosures regarding options sold.
7. Goodwill and Other Intangible Assets
Goodwill
There were no changes in the carrying amount of goodwill during the three and nine months ended September 30, 2024 and 2023. No accumulated goodwill impairment losses existed at September 30, 2024 and December 31, 2023. Goodwill is reviewed annually for impairment and more frequently if potential impairment indicators exist. No impairment indicators were identified during the three and nine months ended September 30, 2024 and 2023. All of the Company's goodwill is associated
17
with the Property and Casualty business segment. See Note 13. Segment Information for additional information on the reportable business segment.

8. Share-Based Compensation

In February 2015, the Company's Board of Directors (the "Board") adopted the 2015 Incentive Award Plan (the "2015 Plan"), replacing the 2005 Equity Incentive Plan which expired in January 2015. The 2015 Plan was approved at the Company's Annual Meeting of Shareholders in May 2015. A maximum of 4,900,000 shares of common stock are authorized for issuance under the 2015 Plan, with 4,830,000 shares of common stock available for future grant as of September 30, 2024 upon exercise of stock options, stock appreciation rights and other awards, or upon vesting of restricted stock unit ("RSU") or deferred stock awards.

In February 2024, the Board adopted the 2024 Long-Term Incentive Plan (the “LTIP”) to provide certain key employees with the right to receive cash awards providing an opportunity to participate in the appreciation of the Company’s value and in order to retain these key employees and reward them for contributing to the success of the Company. Participants in the LTIP
18
may be granted a number of notional interests, or phantom stock units ("PSUs"). Each PSU represents the right to receive payment of the value of a share of the Company’s common stock upon vesting. PSUs may be granted subject to vesting conditions, which may include service-based and/or performance-based vesting conditions tied to corporate and/or individual achievement objectives. An employee must remain employed through the date of payment of an award to be eligible for any payout under the LTIP. These PSUs are settled in cash upon vesting and accounted for as liability-based awards.

Stock Options

In February 2018, the Compensation Committee of the Board awarded a total of 80,000 stock options to four senior executives under the 2015 Plan, which vested over the four-year requisite service period and had a term of ten years from the date of grant, except for 10,000 of these stock options that were forfeited in February 2019 following the departure of a senior executive. The fair values of these stock options were estimated on the date of grant using a closed-form option valuation model (Black-Scholes).
As of September 30, 2024, 17,500 of the total stock options awarded and vested under the 2015 Plan have not been exercised, each with a remaining term of approximately 3.4 years.
Performance-based PSUs
During the nine months ended September 30, 2024, the Company granted a total "target" award of 200,532 performance-based PSUs to certain executive officers and other key employees of the Company, 3,016 of which were forfeited because the recipients were no longer employed by the Company. The payout value of the performance-based PSUs granted under the LTIP will be determined based on the achievement of specific, pre-established corporate performance objectives, and in part on individual performance, during the applicable three-year performance period (the "Performance Cycle"). The maximum payout level for the performance-based PSUs is 150% of the “target” award.
The following table presents the summary of the performance-based PSU grants as of September 30, 2024:
    
Grant year2024
Three-year performance period ending December 31,
2026
Vesting shares, target (net of forfeited)197,516
Vesting shares, maximum (net of forfeited)296,274

These performance-based PSUs vest at the end of the Performance Cycle beginning with the year of the grant, and then only if, and to the extent that, the Company’s performance during the Performance Cycle achieves the threshold established by the Compensation Committee of the Board. Each annual performance result is determined based on the average of the Company’s annual market share growth and its annual combined ratio. The vested number of performance-based PSUs for each grantee is based on the average of the Company's three annual performance results combined with the individual's performance during the Performance Cycle. The cash payout amount for each unit of the vested performance-based PSUs is equal to the average closing price per share of the Company’s common stock for the 30 calendar days preceding the determination of the final number of vested PSUs for each grantee at the end of the Performance Cycle.

Liabilities for the expected cash payout and associated compensation expenses are recognized based on management’s best estimate of the number of the performance-based PSUs expected to be vested resulting from the probable outcome of the performance-based vesting conditions, combined with the market price of the Company's common stock at the end of each reporting period. If the performance-based vesting conditions are not expected to be met for the Performance Cycle, no compensation cost will be recognized and any recognized compensation cost will be reversed.
Restricted PSUs

The Company, from time to time, grants restricted PSUs to certain key employees, typically to retain such key employees. The restricted PSUs vest in three equal annual installments on each of the first three anniversaries of the grant date. The payout value of the restricted PSUs granted under the LTIP will be determined based on the closing price per share of the Company's common stock at each vesting date. The vested amount of the restricted PSUs is paid at the end of each annual vesting period. During the nine months ended September 30, 2024, the Company granted a total of 25,102 restricted PSUs to certain key employees of the Company, 726 of which were forfeited because the recipients were no longer employed by the Company.
The Company recorded approximately $1.5 million and $3.2 million of share-based compensation expense associated with the performance-based and restricted PSUs for the three and nine months ended September 30, 2024, respectively, which are included in other operating expenses in its consolidated statements of operations.

9. Income Taxes

For financial statement purposes, the Company recognizes tax benefits related to positions taken, or expected to be taken, on a tax return only if the positions are “more-likely-than-not” sustainable. Once this threshold has been met, the Company’s measurement of its expected tax benefits is recognized in its consolidated financial statements.

The total amount of unrecognized tax benefits related to tax uncertainties decreased by approximately $2.3 million during the nine months ended September 30, 2024, primarily resulting from the payment of the assessed amount related to a California Franchise Tax Board audit for tax year 2011, which has now been resolved with no outstanding issues.

The Company and its subsidiaries file income tax returns with the Internal Revenue Service and the taxing authorities of various states. Tax years that remain subject to examination by major taxing jurisdictions are 2021 through 2023 for federal taxes and 2020 through 2023 for state taxes.

Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial reporting basis and the respective tax basis of the Company’s assets and liabilities, and expected benefits of utilizing net operating loss, capital loss, and tax-credit carryforwards. The Company assesses the likelihood that its deferred tax assets will be realized and, to the extent management does not believe these assets are more likely than not to be realized, a valuation allowance is established. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates or laws is recognized in net income (loss) in the period that includes the enactment date.

At September 30, 2024, the Company’s deferred income taxes were in a net asset position, which included a combination of ordinary and capital deferred tax expenses or benefits. In assessing the Company’s ability to realize deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon generating sufficient taxable income of the appropriate character within the carryback and carryforward periods available under the tax law. Management considers the reversal of deferred tax liabilities, projected future taxable income of an appropriate nature, and tax planning strategies in making this assessment. The Company believes that through projected future taxable income of an appropriate nature, the use of prudent tax planning strategies, and the generation of capital gains, sufficient income will be realized in order to maximize the full benefits of its deferred tax assets. Although realization is not assured, management believes that it is more likely than not that the Company’s deferred tax assets will be realized.

The increase in the provision for insured events of prior years during the nine months ended September 30, 2024 of $16.5 million was primarily attributable to higher than estimated losses and loss adjustment expenses in the commercial automobile and commercial property lines of insurance business and catastrophe losses, partially offset by favorable development in the private passenger automobile and homeowners lines of insurance business. The decrease in the provision for insured events of prior years during the nine months ended September 30, 2023 of $32.1 million was primarily attributable to lower than estimated losses and loss adjustment expenses in the private passenger automobile and homeowners lines of insurance business, partially offset by unfavorable development in the commercial property line of insurance business.

For the nine months ended September 30, 2024 and 2023, the Company incurred catastrophe losses net of reinsurance of approximately $236 million and $223 million, respectively. The majority of 2024 catastrophe losses resulted from tornadoes, hailstorms and convective storms in Texas and Oklahoma, winter storms and rainstorms in California, and the impact of Hurricane Helene in Florida and Georgia. The majority of 2023 catastrophe losses resulted from winter storms and rainstorms in California, Texas and Oklahoma, and the impact of Hurricane Hilary in California. The Company experienced unfavorable development of approximately $7 million and favorable development of approximately $4 million on prior years' catastrophe losses for the nine months ended September 30, 2024 and 2023, respectively.

Total debt$574,028 $573,729 
__________ 
(1)On March 8, 2017, the Company completed a public debt offering issuing $375 million of senior notes. The notes are unsecured, senior obligations of the Company with a 4.4% annual coupon payable on March 15 and September 15 of each year commencing September 15, 2017. The Company used the proceeds from the notes to pay off amounts outstanding under the existing loan and credit facilities and for general corporate purposes. The Company incurred debt issuance costs of approximately $3.4 million, inclusive of underwriters' fees. The notes were issued at a slight discount of 99.847% of par, resulting in the effective annualized interest rate, including debt issuance costs, of approximately 4.45%.
(2)On March 31, 2021, the Company entered into an unsecured $75 million five-year revolving credit facility. On November 18, 2022, the Company entered into the First Amendment to this credit facility. The First Amendment extended the maturity date of the loan to November 16, 2026 from March 31, 2026 with possible further extension if certain conditions are met, increased the aggregate commitments by all the lenders to $200 million from $75 million, and replaced the LIBOR with the Term SOFR. On November 30, 2023, the Company entered into the Second Amendment to this credit facility, which further increased the aggregate commitments by all the lenders to $250 million from $200 million. The interest rates on borrowings under the credit facility are based on the Company's debt to total capital ratio and range from Term SOFR plus 112.5 basis points when the ratio is under 20% to Term SOFR plus 150.0 basis points when the ratio is greater than or equal to 30%. Commitment fees for the undrawn portions of the credit facility range from 12.5 basis points when the ratio is under 20% to 22.5 basis points when the ratio is greater than or equal to 30%. The debt to total capital ratio is expressed as a percentage of (a) consolidated debt to (b) consolidated shareholders' equity plus consolidated debt. The Company's debt to total capital ratio was 23.6% at September 30, 2024, resulting in a 15.0 basis point commitment fee on any undrawn portion of the credit facility. As of October 24, 2024, a total of $200 million was drawn under this facility on a three-month revolving basis at an annual interest rate of approximately 6.47%, with $50 million available to be drawn. The Company contributed $150 million of the total amount drawn to the surplus of its consolidated insurance subsidiaries, and used the remainder for general corporate purposes.
(3)The unamortized discount and debt issuance costs are associated with the publicly traded $375 million senior unsecured notes. These are amortized to interest expense over the life of the notes, and the unamortized balance is presented in the
21
Company's consolidated balance sheets as a direct deduction from the carrying amount of the debt. The unamortized costs of approximately $0.7 million associated with entering into the $250 million unsecured revolving credit facility maturing on November 16, 2026 are included in other assets in the Company's consolidated balance sheets and amortized to interest expense over the term of the credit facility.
12. Contingencies

The Company is, from time to time, named as a defendant in various lawsuits or regulatory actions incidental to its insurance business. The majority of lawsuits brought against the Company relate to insurance claims that arise in the normal course of business and are reserved for through the reserving process. For a discussion of the Company’s reserving methods, see the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

On September 10, 2021, the California Department of Insurance ("DOI") served the Company a Notice of Non-Compliance ("NNC"), alleging violations in connection with its 2014 Rating & Underwriting Examination Report, which was adopted by the California DOI in 2019. The NNC itemizes alleged violations, many of which management believes were corrected or otherwise resolved during the course of the examination, and seeks penalties. The Company has participated in lengthy and detailed discussions with the California DOI since the adoption of the examination report, in an attempt to address the issues deemed unresolved by the California DOI, and has taken several additional corrective actions approved by the California DOI. On August 1, 2022, the California DOI publicly announced its intention to pursue an administrative action against the Company with respect to certain outstanding issues. The Company served a written response to the NNC on September 29, 2022, along with written discovery requests. The response, consisting of a notice of defense, a motion to strike, and a motion to dismiss, challenges the NNC on procedural and substantive grounds. On November 9, 2022, the California DOI served objections and non-substantive responses to the Company's discovery requests. On November 14, 2023, the California DOI granted Consumer Watchdog's petition to intervene in the NNC, although the Company did not agree to allow its involvement in the mediation, which took place on March 4, 2024. The parties did not make any meaningful progress toward settlement, but are continuing settlement discussions. The parties are also conferring regarding the possible filing of an Amended NNC that would eliminate the resolved items and identify the remaining issues in dispute should the matter proceed to a hearing. The Company cannot reasonably predict the likelihood, timing or outcome of any hearing process or administrative action, nor can it reasonably estimate the amount of penalties, if any.

The Company establishes reserves for non-insurance claims related lawsuits, regulatory actions, and other contingencies when the Company believes a loss is probable and is able to estimate its potential exposure. For loss contingencies believed to be reasonably possible, the Company also discloses the nature of the loss contingency and an estimate of the possible loss, range of loss, or a statement that such an estimate cannot be made. In addition, the Company accrues for anticipated legal defense costs associated with such lawsuits and regulatory actions. While actual losses may differ from the amounts recorded and the ultimate outcome of the Company's pending actions is generally not yet determinable, the Company does not believe that the ultimate resolution of currently pending legal or regulatory proceedings, either individually or in the aggregate, will have a material adverse effect on its financial condition or cash flows.

In all cases, the Company vigorously defends itself unless a reasonable settlement appears appropriate. For a discussion of any additional regulatory or legal matters, see the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

13. Segment Information

The Company is primarily engaged in writing personal automobile insurance and provides related property and casualty insurance products to its customers through 12 subsidiaries in 11 states, principally in California.
The Company has one reportable business segment - the Property and Casualty business segment.
The Company’s CODM evaluates operating results based on pre-tax underwriting results which is calculated as net premiums earned less (a) losses and loss adjustment expenses and (b) underwriting expenses (policy acquisition costs and other operating expenses).
Expenses are allocated based on certain assumptions that are primarily related to premiums and losses. The Company’s net investment income, net realized investment gains or losses, other income, and interest expense are excluded in evaluating pretax underwriting profit. The Company does not allocate its assets, including investments, or income taxes in evaluating pre-tax underwriting profit.

22
Property and Casualty Lines
The Property and Casualty business segment offers several insurance products to the Company’s individual customers and small business customers. These insurance products are: private passenger automobile which is the Company’s primary business, and related insurance products such as homeowners, commercial automobile and commercial property. These related insurance products are primarily sold to the Company’s individual customers and small business customers, which increases retention of the Company’s private passenger automobile client base. The insurance products comprising the Property and Casualty business segment are sold through the same distribution channels, mainly through independent and 100% owned insurance agents, and go through a similar underwriting process.

Other Lines

The Other business segment represents net premiums written and earned from an operating segment that does not meet the quantitative thresholds required to be considered a reportable segment. This operating segment offers automobile mechanical protection warranties which are primarily sold through automobile dealerships and credit unions.

OVERVIEW
A. General

The operating results of property and casualty insurance companies are subject to significant quarter-to-quarter and year-to-year fluctuations due to the effect of competition on pricing, the frequency and severity of losses, the effect of weather and natural disasters on losses, general economic conditions, the general regulatory environment in states in which an insurer operates, state regulation of insurance including premium rates, changes in fair value of investments, and other factors such as changes in tax laws. The property and casualty insurance industry has been highly cyclical, with periods of high premium rates and shortages of underwriting capacity followed by periods of severe price competition and excess capacity. These cycles can have a significant impact on the Company’s ability to grow and retain business.

This section discusses some of the relevant factors that management considers in evaluating the Company’s performance, prospects, and risks. It is not all-inclusive and is meant to be read in conjunction with the entirety of management’s discussion and analysis, the Company’s consolidated financial statements and notes thereto, and all other items contained within this Quarterly Report on Form 10-Q.

B. Business

The Company is primarily engaged in writing personal automobile insurance through 12 insurance subsidiaries (“Insurance Companies”) in 11 states, principally California. The Company also writes homeowners, commercial automobile, commercial property, mechanical protection, and umbrella insurance. The Company's insurance policies are mostly sold through independent agents who receive a commission for selling policies. The Company believes that it has thorough underwriting and claims handling processes that, together with its agent relationships, provide the Company with competitive advantages.

C. Regulatory and Legal Matters

The Department of Insurance (“DOI”) in each state in which the Company operates is responsible for conducting periodic financial, market conduct, and rating and underwriting examinations of the Insurance Companies in their states. Market conduct examinations typically review compliance with insurance statutes and regulations with respect to rating, underwriting, claims handling, billing, and other practices.

The following table presents a summary of recent and upcoming examinations:

StateExam TypeExam Period CoveredStatus
TXMarket Conduct2022Examination commenced in the fourth quarter of 2023.

During the course of and at the conclusion of the examinations, the examining DOI generally reports findings to the Company. No material findings have been communicated to the Company on the ongoing Texas market conduct examination noted above.

In January 2023, the California DOI approved a 6.9% rate increase on the private passenger automobile line of insurance business for Mercury Insurance Company ("MIC") and California Automobile Insurance Company ("CAIC"), consolidated subsidiaries of the Company. These rate increases became effective in March 2023. The California DOI approved an additional 6.99% rate increase on the private passenger automobile line of insurance business for MIC and CAIC in June 2023. These rate increases became effective in July 2023. In addition, in January 2024, the California DOI approved a 22.5% rate increase for MIC and a 3.8% rate increase for CAIC on the private passenger automobile line of insurance business. These rate increases became effective in February 2024. The private passenger automobile line of insurance business of MIC and CAIC represented approximately 47% and 6%, respectively, of the Company's total net premiums earned for the nine months ended September 30, 2024.

In March 2023, the California DOI approved a 12.6% rate increase on the California homeowners line of insurance business. This rate increase became effective in May 2023. In March 2024, the California DOI approved an additional 6.99% rate increase on the California homeowners line of insurance business. This rate increase became effective in May 2024. The
26
California homeowners line of insurance business represented approximately 16% of the Company's total net premiums earned for the nine months ended September 30, 2024.

The Company is, from time to time, named as a defendant in various lawsuits or regulatory actions incidental to its insurance business. The majority of lawsuits brought against the Company relate to insurance claims that arise in the normal course of business and are reserved for through the reserving process. For a discussion of the Company’s reserving methods, see the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

The Company establishes reserves for non-insurance claims related lawsuits, regulatory actions, and other contingencies when the Company believes a loss is probable and is able to estimate its potential exposure. For loss contingencies believed to be reasonably possible, the Company also discloses the nature of the loss contingency and an estimate of the possible loss, range of loss, or a statement that such an estimate cannot be made. In addition, the Company accrues for anticipated legal defense costs associated with such lawsuits and regulatory actions. While actual losses may differ from the amounts recorded and the ultimate outcome of the Company's pending actions is generally not yet determinable, the Company does not believe that the ultimate resolution of currently pending legal or regulatory proceedings, either individually or in the aggregate, will have a material adverse effect on its financial condition or cash flows.

In all cases, the Company vigorously defends itself unless a reasonable settlement appears appropriate. For a discussion of any additional regulatory or legal matters, see the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, and Note 12. Contingencies of the Notes to Consolidated Financial Statements of this Quarterly Report.

D. Critical Accounting Estimates

Loss and Loss Adjustment Expense Reserves ("Loss Reserves")

Preparation of the Company’s consolidated financial statements requires management’s judgment and estimates. The most significant is the estimate of loss reserves. Estimating loss reserves is a difficult process as many factors can ultimately affect the final settlement of a claim and, therefore, the loss reserve that is required. A key assumption in estimating loss reserves is the degree to which the historical data used to analyze reserves will be predictive of ultimate claim costs on incurred claims. Changes in the regulatory and legal environments, results of litigation, medical costs, the cost of repair materials, and labor rates, among other factors, can impact this assumption. In addition, time can be a critical part of reserving determinations since the longer the span between the incidence of a loss and the payment or settlement of a claim, the more variable the ultimate settlement amount could be. Accordingly, short-tail claims, such as property damage claims, tend to be more reasonably predictable than long-tail liability claims.

The Company calculates a loss reserve point estimate rather than a range. There is inherent uncertainty with estimates and this is particularly true with loss reserve estimates. This uncertainty comes from many factors which may include changes in claims reporting and settlement patterns, changes in the regulatory and legal environments, uncertainty over inflation rates, and uncertainty for unknown items. The Company does not make specific provisions for these uncertainties, rather it considers them in establishing its loss reserve by reviewing historical patterns and trends and projecting these out to current loss reserves. The underlying factors and assumptions that serve as the basis for preparing the loss reserve estimate include paid and incurred loss development factors, expected average costs per claim, inflation trends, expected loss ratios, industry data, and other relevant information.

The Company also engages independent actuarial consultants to review the Company’s loss reserves and to provide the annual actuarial opinions under statutory accounting principles as required by state regulation. The Company analyzes loss reserves quarterly primarily using the incurred loss, paid loss, average severity coupled with the claim count development methods, and the generalized linear model ("GLM") described below. When deciding among methods to use, the Company evaluates the credibility of each method based on the maturity of the data available and the claims settlement practices for each particular line of insurance business or coverage within a line of insurance business. The Company may also evaluate qualitative factors such as known changes in laws or legal rulings that could affect claims handling or other external environmental factors or internal factors that could affect the settlement of claims. When establishing the loss reserve, the Company will generally analyze the results from all of the methods used rather than relying on a single method. While these methods are designed to determine the ultimate losses on claims under the Company’s policies, there is inherent uncertainty in all actuarial models since they use historical data to project outcomes. The Company believes that the techniques it uses provide a reasonable basis in estimating loss reserves.

•The incurred loss method analyzes historical incurred case loss (case reserves plus paid losses) development to estimate ultimate losses. The Company applies development factors against current case incurred losses by accident
27
period to calculate ultimate expected losses. The Company believes that the incurred loss method provides a reasonable basis for evaluating ultimate losses, particularly in the Company’s larger, more established lines of insurance business which have a long operating history.
•The paid loss method analyzes historical payment patterns to estimate the amount of losses yet to be paid.
•The average severity method analyzes historical loss payments and/or incurred losses divided by closed claims and/or total claims to calculate an estimated average cost per claim. From this, the expected ultimate average cost per claim can be estimated. The average severity method coupled with the claim count development method provide meaningful information regarding inflation and frequency trends that the Company believes is useful in establishing loss reserves. The claim count development method analyzes historical claim count development to estimate future incurred claim count development for current claims. The Company applies these development factors against current claim counts by accident period to calculate ultimate expected claim counts.
•The GLM determines an average severity for each percentile of claims that have been closed as a percentage of estimated ultimate claims. The average severities are applied to open claims to estimate the amount of losses yet to be paid. The GLM utilizes operational time, determined as a percentile of claims closed rather than a finite calendar period, which neutralizes the effect of changes in the timing of claims handling.

The Company analyzes catastrophe losses separately from non-catastrophe losses. For catastrophe losses, the Company generally determines claim counts based on claims reported and development expectations from previous catastrophes and applies an average expected loss per claim based on loss reserves established by adjusters and average losses on previous similar catastrophes. For catastrophe losses on individual properties that are expected to be total losses, the Company typically establishes reserves at the policy limits.
At September 30, 2024 and December 31, 2023, the Company recorded its point estimate of approximately $3.07 billion and $2.79 billion ($3.04 billion and $2.75 billion, net of reinsurance), respectively, in loss reserves, which included approximately $1.85 billion and $1.61 billion ($1.85 billion and $1.61 billion, net of reinsurance), respectively, of incurred but not reported loss reserves (“IBNR”). IBNR includes estimates, based upon past experience, of ultimate developed costs, which may differ from case estimates, unreported claims that occurred on or prior to September 30, 2024 and December 31, 2023, and estimated future payments for reopened claims. Management believes that the liability for loss reserves is adequate to cover the ultimate net cost of losses and loss adjustment expenses incurred to date; however, since the provisions are necessarily based upon estimates, the ultimate liability may be more or less than such provisions.
The Company evaluates its loss reserves quarterly. When management determines that the estimated ultimate claim cost requires a decrease for previously reported accident years, favorable development occurs and a reduction in losses and loss adjustment expenses is reported in the current period. If the estimated ultimate claim cost requires an increase for previously reported accident years, unfavorable development occurs and an increase in losses and loss adjustment expenses is reported in the current period.

RESULTS OF OPERATIONS
Three Months Ended September 30, 2024 Compared to Three Months Ended September 30, 2023

Revenues

Net premiums earned increased 21.1% and net premiums written increased 17.9% for the three months ended September 30, 2024, from the corresponding period in 2023. The increases in net premiums earned and net premiums written were primarily due to rate increases in the California automobile and homeowners lines of insurance business and an increase in the number of policies written in the California homeowners line of insurance business.

Net premiums earned included ceded premiums earned of $42.4 million and $30.9 million for the three months ended September 30, 2024 and 2023, respectively. Net premiums written included ceded premiums written of $42.9 million and $30.9 million for the three months ended September 30, 2024 and 2023, respectively. The increases in ceded premiums earned and ceded premiums written resulted mostly from higher reinsurance coverage and rates and growth in the covered book of business.

28
Net premiums earned, a GAAP measure, represents the portion of net premiums written that is recognized as revenue in the financial statements for the periods presented and earned on a pro-rata basis over the term of the policies. Net premiums written is a non-GAAP financial measure which represents the premiums charged on policies issued during a fiscal period, net of any applicable reinsurance. Net premiums written is a statutory measure designed to determine production levels.

The following is a reconciliation of net premiums earned to net premiums written:
 Three Months Ended September 30,
 20242023
 (Amounts in thousands)
Net premiums earned$1,320,652 $1,090,311 
Change in net unearned premiums102,281 116,192 
Net premiums written$1,422,933 $1,206,503 

Expenses

Loss and expense ratios are used to interpret the underwriting experience of property and casualty insurance companies. The following table presents the Insurance Companies’ loss, expense, and combined ratios determined in accordance with GAAP:
 Three Months Ended September 30,
 20242023
Loss ratio69.5 %75.6 %
Expense ratio24.0 %23.0 %
Combined ratio (1)
93.6 %98.6 %
__________ 
(1) Combined ratio for the three months ended September 30, 2024 does not sum due to rounding.

Loss ratio is calculated by dividing losses and loss adjustment expenses by net premiums earned. The loss ratio for the third quarter of 2024 and 2023 was affected by unfavorable development of approximately $8 million and favorable development of approximately $12 million, respectively, on prior accident years' loss and loss adjustment expense reserves. The unfavorable development for the third quarter of 2024 was primarily attributable to higher than estimated losses and loss adjustment expenses in the automobile line of insurance business. The favorable development for the third quarter of 2023 was primarily attributable to lower than estimated losses and loss adjustment expenses in the private passenger automobile and homeowners lines of insurance business, partially offset by unfavorable development in the commercial property line of insurance business.

In addition, the 2024 loss ratio was negatively impacted by approximately $41 million of catastrophe losses, excluding favorable development of approximately $2 million on prior years' catastrophe losses, primarily due to the impact of Hurricane Helene in Florida and Georgia. The 2023 loss ratio was negatively impacted by approximately $36 million of catastrophe losses, excluding favorable development of approximately $3 million on prior years' catastrophe losses, primarily due to the impact of Hurricane Hilary in California and extreme weather events outside of California.

Excluding the effects of estimated prior accident years’ loss development and catastrophe losses, the loss ratio was 65.8% and 73.4% for the third quarter of 2024 and 2023, respectively. The decrease in the loss ratio was primarily due to rate increases in the California automobile and homeowners lines of insurance business, partially offset by increases in loss frequency and severity in the California private passenger automobile line of insurance business.

Expense ratio is calculated by dividing the sum of policy acquisition costs and other operating expenses by net premiums earned. The expense ratio for the three months ended September 30, 2024 increased compared to the corresponding period in 2023, which primarily resulted from increases in expenses for profitability-related accruals and advertising, partially offset by the rate increases discussed above.

Combined ratio is equal to loss ratio plus expense ratio and is the key measure of underwriting performance traditionally used in the property and casualty insurance industry. A combined ratio under 100% generally reflects profitable underwriting results, and a combined ratio over 100% generally reflects unprofitable underwriting results.
29
Income tax expense (benefit) was $56.2 million and $(7.0) million for the three months ended September 30, 2024 and 2023, respectively. The increase in income tax expense was primarily due to a $302.3 million increase in total pre-tax income. The Company’s effective income tax rate can be affected by several factors. These generally relate to large changes in the composition of fully taxable income, including net realized investment gains or losses, tax-exempt investment income, non-deductible expenses, and periodically, non-routine tax items such as adjustments to unrecognized tax benefits related to tax uncertainties. Income tax expense of $56.2 million on pre-tax income of $287.1 million, including tax-exempt investment income of $21.3 million, resulted in an effective tax rate of 19.6%, below the statutory tax rate of 21%, for the three months ended September 30, 2024, and income tax benefit of $7.0 million on pre-tax loss of $15.2 million, including tax-exempt investment income of $22.0 million, resulted in an effective tax rate of 46.0%, above the statutory tax rate, for the corresponding period in 2023.

Average annual yield on investments does not include interest income earned on cash.
(3) Higher net investment income before and after income taxes for the three months ended September 30, 2024 compared to the corresponding period in 2023 resulted largely from higher average yield combined with higher average invested assets and cash. Average annual yield on investments before and after income taxes for the three months ended September 30, 2024 increased compared to the corresponding period in 2023, primarily due to the maturity and replacement of lower yielding investments purchased when market interest rates were lower with higher yielding investments.

Nine Months Ended September 30, 2024 Compared to Nine Months Ended September 30, 2023

Revenues

Net premiums earned increased 19.0% and net premiums written increased 21.9% for the nine months ended September 30, 2024, from the corresponding period in 2023. The increases in net premiums earned and net premiums written were primarily due to rate increases in the California automobile and homeowners lines of insurance business and an increase in the number of policies written in the California homeowners line of insurance business.

Net premiums earned included ceded premiums earned of $104.9 million and $78.1 million for the nine months ended September 30, 2024 and 2023, respectively. Net premiums written included ceded premiums written of $106.1 million and $78.5 million for the nine months ended September 30, 2024 and 2023, respectively. The increases in ceded premiums earned and ceded premiums written resulted mostly from higher reinsurance coverage and rates and growth in the covered book of business.

 20242023
Loss ratio74.1 %84.7 %
Expense ratio23.5 %23.2 %
Combined ratio97.6 %107.9 %

The loss ratio for the nine months ended September 30, 2024 and 2023 was affected by unfavorable development of approximately $16 million and favorable development of approximately $32 million, respectively, on prior accident years' loss and loss adjustment expense reserves. The unfavorable development for the nine months ended September 30, 2024 was primarily attributable to higher than estimated losses and loss adjustment expenses in the commercial automobile and commercial property lines of insurance business and catastrophe losses, partially offset by favorable development in the private passenger automobile and homeowners lines of insurance business. The favorable development for the nine months ended September 30, 2023 was primarily attributable to lower than estimated losses and loss adjustment expenses in the private passenger automobile and homeowners lines of insurance business, partially offset by unfavorable development in the commercial property line of insurance business.

In addition, the 2024 loss ratio was negatively impacted by approximately $229 million of catastrophe losses, excluding unfavorable development of approximately $7 million on prior years' catastrophe losses, primarily due to tornadoes, hailstorms and convective storms in Texas and Oklahoma, winter storms and rainstorms in California, and the impact of Hurricane Helene in Florida and Georgia. The 2023 loss ratio was negatively impacted by approximately $227 million of catastrophe losses, excluding favorable development of approximately $4 million on prior years' catastrophe losses, primarily due to winter storms and rainstorms in California, Texas and Oklahoma, and the impact of Hurricane Hilary in California.

Excluding the effects of estimated prior accident years’ loss development and catastrophe losses, the loss ratio was 67.5% and 78.5% for the nine months ended September 30, 2024 and 2023, respectively. The decrease in the loss ratio was primarily due to rate increases in the California automobile and homeowners lines of insurance business, partially offset by increases in loss frequency and severity in the California private passenger automobile line of insurance business.
The expense ratio for the nine months ended September 30, 2024 increased compared to the corresponding period in 2023, which primarily resulted from increases in expenses for profitability-related accruals and advertising, partially offset by the rate increases discussed above.
Income tax expense (benefit) was $84.5 million and $(43.5) million for the nine months ended September 30, 2024 and 2023, respectively. The increase in income tax expense was primarily due to a $589.9 million increase in total pre-tax income. Income tax expense of $84.5 million on pre-tax income of $451.4 million, including tax-exempt investment income of $61.9 million, resulted in an effective tax rate of 18.7%, below the statutory tax rate of 21%, for the nine months ended September 30, 2024, and income tax benefit of $43.5 million on pre-tax loss of $138.5 million, including tax-exempt investment income of $65.8 million, resulted in an effective tax rate of 31.4%, above the statutory tax rate, for the corresponding period in 2023.

LIQUIDITY AND CAPITAL RESOURCES

A. Cash Flows

The Company has generated positive cash flow from operations each year since the public offering of its common stock in November 1985. The Company does not attempt to match the duration and timing of asset maturities with those of liabilities; rather, it manages its portfolio with a view towards maximizing total return with an emphasis on after-tax income. With combined cash and short-term investments of $905.0 million at September 30, 2024, the Company believes its cash flow from operations is adequate to satisfy its liquidity requirements without the forced sale of investments. Investment maturities are also available to meet the Company’s liquidity needs. However, the Company operates in a rapidly evolving and often unpredictable business environment that may change the timing or amount of expected future cash receipts and expenditures. Accordingly, there can be no assurance that the Company’s sources of funds will be sufficient to meet its liquidity needs or that the Company will not be required to raise additional funds to meet those needs or for future business expansion, through the sale of equity or debt securities or from credit facilities with lending institutions.

34
Net cash provided by operating activities for the nine months ended September 30, 2024 was $788.8 million, an increase of $561.1 million compared to the corresponding period in 2023. The increase was primarily due to an increase in premium collections, a decrease in payments for losses and loss adjustment expenses, and an increase in investment income received, partially offset by increases in payments for policy acquisition costs and taxes. The Company utilized the cash provided by operating activities during the nine months ended September 30, 2024 primarily for the net purchases of investment securities and payment of dividends to its shareholders.

The following table presents the estimated fair value of fixed maturity securities at September 30, 2024 by contractual maturity in the next five years:

Due after three years through four years223,022 
Due after four years through five years199,958 
Total due within five years$1,394,133 

B. Reinsurance
For California homeowners policies, the Company has reduced its catastrophe exposure from earthquakes by placing earthquake risks directly with the California Earthquake Authority ("CEA"). However, the Company continues to have catastrophe exposure to fires following an earthquake.
The Company is the assuming reinsurer under a Catastrophe Participation Reinsurance Contract (the "Contract") effective through December 31, 2025. The Company reimburses a group of affiliates of a ceding company for a proportional share of a portfolio of catastrophe losses based on the premiums ceded to the Company under the Contract, to the extent the actual loss ratio exceeds the threshold loss ratio of 73.5%. The total assumed premium under the Contract is $15.0 million for each of the 12-month periods ending December 31, 2023 through 2025 and $10.0 million for the 12 months ended December 31, 2022. The total possible amount of losses for the Company under the Contract is $30.0 million for each of the 12-month periods ending December 31, 2023 through 2025 and $25.0 million for the 12 months ended December 31, 2022. The Company recognized $3.8 million in earned premiums for each of the three-month periods ended September 30, 2024 and 2023, and $2.1 million and $2.2 million in incurred losses for the three months ended September 30, 2024 and 2023, respectively, and $11.3 million in earned premiums for each of the nine-month periods ended September 30, 2024 and 2023, and $(0.3) million and $7.6 million in incurred losses for the nine months ended September 30, 2024 and 2023, respectively, under the Contract. The negative incurred losses for the nine months ended September 30, 2024 resulted primarily from favorable development on prior years' catastrophe losses that had been ceded to the Company under the Contract.

The Company is the ceding party to a Catastrophe Reinsurance Treaty (the "Treaty") covering a wide range of perils that is effective through June 30, 2025. For the 12 months ending June 30, 2025 and 2024, the Treaty provides approximately $1,290 million and $1,111 million of coverage, respectively, on a per occurrence basis after covered catastrophe losses exceed the Company retention limit of $150 million and $100 million, respectively. The Treaty specifically excludes coverage for any Florida business and for California earthquake losses on fixed property policies such as homeowners, but does cover losses from fires following an earthquake. The Treaty includes additional restrictions as noted in the tables below.

Coverage on individual catastrophes provided for the 12 months ending June 30, 2025 under the Treaty is presented below in various layers:

$105 $— $105 
For the 12 months ended June 30, 2024$99 $— $99 
__________ 
(1) The increase in the annual premium is primarily due to an increase in reinsurance coverage and rates and growth in the covered book of business.
(2) The reinstatement premium and the total combined premium for the treaty period ending June 30, 2025 are projected amounts to be paid based on the assumption that there will be no reinstatements occurring during this treaty period. The reinstatement premium for the treaty period ended June 30, 2024 is zero, as there were no actual reinstatement premiums paid.

The Treaty ending June 30, 2025 and 2024 each provides for one full reinstatement of coverage limits. Reinstatement premiums are based on the amount of reinsurance benefits used by the Company at 100% of the annual premium rate, with the exception of the reinstatement restrictions noted in the tables above, up to the maximum reinstatement premium of approximately $101 million and $95 million if the full amount of benefit is used for the 12 months ending June 30, 2025 and 2024, respectively.

The total amount of reinstatement premiums is recorded as ceded reinstatement premiums written at the time of the catastrophe event based on the total amount of reinsurance benefits expected to be used for the event, and such reinstatement premiums are recognized ratably over the remaining term of the Treaty as ceded reinstatement premiums earned.

The catastrophe events that occurred in 2024 caused approximately $229 million in losses to the Company, resulting primarily from tornadoes, hailstorms and convective storms in Texas and Oklahoma, winter storms and rainstorms in California, and the impact of Hurricane Helene in Florida and Georgia. No reinsurance benefits were available under the Treaty for these losses as none of the 2024 catastrophe events individually resulted in losses in excess of the Company’s per-occurrence retention limit of $150 million and $100 million under the Treaty for the 12 months ending June 30, 2025 and 2024, respectively.

The catastrophe events that occurred in 2023 caused approximately $256 million in losses to the Company as of September 30, 2024, resulting primarily from rainstorms and hail in Texas and Oklahoma, winter storms and rainstorms in California, and the impact of Tropical Storm Hilary in California. No reinsurance benefits were available under the Treaty for these losses as none of the 2023 catastrophe events individually resulted in losses in excess of the Company’s per-occurrence retention limit of $100 million and $60 million under the Treaty for the 12 months ended June 30, 2024 and 2023, respectively.

The Company carries a commercial umbrella reinsurance treaty and a per-risk property reinsurance treaty, and seeks facultative arrangements for large property risks. In addition, the Company has other reinsurance in force that is not material to the consolidated financial statements. If any reinsurers are unable to perform their obligations under a reinsurance treaty, the Company will be required, as primary insurer, to discharge all obligations to its policyholders in their entirety.

C. Invested Assets

Portfolio Composition

An important component of the Company’s financial results is the return on its investment portfolio. The Company’s investment strategy emphasizes safety of principal and consistent income generation, within a total return framework. The investment strategy has historically focused on maximizing after-tax yield with a primary emphasis on maintaining a well-diversified, investment grade, fixed income portfolio to support the underlying liabilities and achieve return on capital and profitable growth. The Company believes that investment yield is maximized by selecting assets that perform favorably on a long-term basis and by disposing of certain assets to enhance after-tax yield and minimize the potential effect of downgrades and defaults. The Company believes that this strategy enables the optimal investment performance necessary to sustain investment income over time. The Company’s portfolio management approach utilizes a market risk and consistent asset allocation strategy as the primary basis for the allocation of interest sensitive, liquid and credit assets as well as for determining overall below investment grade exposure and diversification requirements. Within the ranges set by the asset allocation strategy, tactical investment decisions are made in consideration of prevailing market conditions.

(2)    The fair value is measured using the NAV practical expedient. See Note 5. Fair Value Measurements of the Notes to Consolidated Financial Statements for additional information.
At September 30, 2024, 37.9% of the Company’s total investment portfolio at fair value and 47.0% of its total fixed maturity securities at fair value were invested in tax-exempt state and municipal bonds. Equity holdings consist of non-redeemable preferred stocks, dividend-bearing common stocks on which dividend income is partially tax-sheltered by the 50% corporate dividend received deduction, and private equity funds. At September 30, 2024, 96.9% of short-term investments
37
consisted of highly rated short-duration securities redeemable on a daily or weekly basis.

Fixed Maturity Securities and Short-Term Investments

Fixed maturity securities include debt securities, which are mostly long-term bonds and other debt with maturities of at least one year from purchase, and which may have fixed or variable principal payment schedules, may be held for indefinite periods of time, and may be used as a part of the Company’s asset/liability strategy or sold in response to changes in interest rates, anticipated prepayments, risk/reward characteristics, liquidity needs, tax planning considerations, or other economic factors. Short-term instruments include money market accounts, options, and short-term bonds that are highly rated short duration securities and redeemable within one year.

A primary exposure for the fixed maturity securities is interest rate risk. The longer the duration, the more sensitive the asset is to market interest rate fluctuations. As assets with longer maturity dates tend to produce higher current yields, the Company’s historical investment philosophy has resulted in a portfolio with a moderate duration. The Company's portfolio is heavily weighted in investment grade tax-exempt municipal bonds. Fixed maturity securities purchased by the Company typically have call options attached, which further reduce the duration of the asset as interest rates decline. The holdings that are heavily weighted with high coupon issues, are expected to be called prior to maturity. Modified duration measures the length of time it takes, on average, to receive the present value of all the cash flows produced by a bond, including reinvestment of interest. As it measures four factors (maturity, coupon rate, yield and call terms) which determine sensitivity to changes in interest rates, modified duration is considered a better indicator of price volatility than simple maturity alone.

Another exposure related to the fixed maturity securities is credit risk, which is managed by maintaining a weighted-average portfolio credit quality rating of A+, at fair value, at September 30, 2024, consistent with the average rating at December 31, 2023. The Company's municipal bond holdings, of which 75.4% were tax exempt, represented 47.0% of its fixed maturity securities portfolio at September 30, 2024, at fair value, and are broadly diversified geographically. See Part I-Item 3. Quantitative and Qualitative Disclosures About Market Risks for a breakdown of municipal bond holdings by state.
To calculate the weighted-average credit quality ratings disclosed throughout this Quarterly Report on Form 10-Q, individual securities were weighted based on fair value and credit quality ratings assigned by nationally recognized securities rating organizations.
Taxable holdings consist principally of investment grade issues. At September 30, 2024, fixed maturity securities holdings rated below investment grade and non-rated bonds totaled $6.2 million and $42.5 million, respectively, at fair value, and represented 0.1% and 0.9%, respectively, of total fixed maturity securities. At December 31, 2023, fixed maturity securities holdings rated below investment grade and non-rated bonds totaled $6.4 million and $15.1 million, respectively, at fair value, and represented 0.1% and 0.3%, respectively, of total fixed maturity securities.
The overall credit ratings for the Company’s fixed maturity securities portfolio were relatively stable during the nine months ended September 30, 2024, with 92.1% of fixed maturity securities at fair value experiencing no change in their overall
38
rating. 6.9% and 0.9% of fixed maturity securities at fair value experienced upgrades and downgrades, respectively, during the nine months ended September 30, 2024.

39
U.S. Government Bonds and Agencies

The Company had $120.6 million and $174.5 million, or 2.5% and 4.0% of its fixed maturity securities portfolio, at fair value, in U.S. government bonds and agencies at September 30, 2024 and December 31, 2023, respectively. Moody's and Fitch ratings for U.S. government-issued debt were Aaa and AA+, respectively, at each of September 30, 2024 and December 31, 2023. The Company understands that market participants continue to use rates of return on U.S. government debt as a risk-free rate and have continued to invest in U.S. Treasury securities. The modified duration of the U.S. government bonds and agencies portfolio reflecting anticipated early calls was 1.1 years and 0.9 years at September 30, 2024 and December 31, 2023, respectively.

Municipal Securities

The Company had $3.03 billion and $2.78 billion, or 62.3% and 64.3% of its fixed maturity securities portfolio, at fair value, in municipal securities, $502.7 million and $431.2 million of which were insured, at September 30, 2024 and December 31, 2023, respectively. The underlying ratings for insured municipal bonds have been factored into the average rating of the securities by the rating agencies with no significant disparity between the absolute securities ratings and the underlying credit ratings as of September 30, 2024 and December 31, 2023.
At September 30, 2024 and December 31, 2023, 71.2% and 70.3%, respectively, of the insured municipal securities, at fair value, most of which were investment grade, were insured by bond insurers that provide credit enhancement and ratings reflecting the credit of the underlying issuers. At each of September 30, 2024 and December 31, 2023, the average rating of the Company’s insured municipal securities was A+, which corresponded to the average rating of the investment grade bond insurers. The remaining 28.8% and 29.7% of insured municipal securities at September 30, 2024 and December 31, 2023, respectively, were non-rated or below investment grade, and were insured by bond insurers that the Company believes did not provide credit enhancement. The modified duration of the municipal securities portfolio reflecting anticipated early calls was 3.1 years and 3.0 years at September 30, 2024 and December 31, 2023, respectively.
The Company considers the strength of the underlying credit as a buffer against potential market value declines which may result from future rating downgrades of the bond insurers. In addition, the Company has a long-term time horizon for its municipal bond holdings, which generally allows it to recover the full principal amounts upon maturity and avoid forced sales prior to maturity of bonds that have declined in market value due to the bond insurers’ rating downgrades. Based on the uncertainty surrounding the financial condition of these insurers, it is possible that there will be future downgrades to below investment grade ratings by the rating agencies in the future, and such downgrades could impact the estimated fair value of municipal bonds.

Mortgage-Backed Securities

The Company had mortgage-backed securities portfolio of $244.9 million and $186.9 million, or 5.0% and 4.3% of the Company's fixed maturity securities portfolio at fair value, at September 30, 2024 and December 31, 2023, respectively. Substantially all of the Company's mortgage-backed securities portfolio at those dates was categorized as loans to “prime” residential and commercial real estate borrowers. The Company had holdings of $28.2 million and $33.0 million at fair value ($28.5 million and $34.2 million at amortized cost) in commercial mortgage-backed securities at September 30, 2024 and December 31, 2023, respectively.
The weighted-average rating of the entire mortgage-backed securities portfolio was AA+ at each of September 30, 2024 and December 31, 2023. The modified duration of the mortgage-backed securities portfolio reflecting anticipated early calls was 5.7 years and 8.7 years at September 30, 2024 and December 31, 2023, respectively.

Equity Securities

Equity holdings of $870.8 million and $730.7 million at fair value, as of September 30, 2024 and December 31, 2023, respectively, consisted of non-redeemable preferred stocks, common stocks on which dividend income is partially tax-sheltered by the 50% corporate dividend received deduction, and private equity funds. The Company had a net gain (loss) of $39.6 million and $(38.8) million due to changes in fair value of the Company’s equity securities portfolio for the nine months ended September 30, 2024 and 2023, respectively. The primary cause for the increase in fair value of the Company’s equity securities portfolio for the nine months ended September 30, 2024 was the overall improvement in equity markets. The primary cause for the decrease in fair value of the Company’s equity securities portfolio for the nine months ended September 30, 2023 was the overall decline in equity markets.

The Company’s common stock allocation is intended to enhance the return of and provide diversification for the total portfolio. At September 30, 2024, 14.5% of the total investment portfolio at fair value was held in equity securities, compared to 14.0% at December 31, 2023 .
D. Debt

The Company's debts at September 30, 2024 were $375 million of senior unsecured notes that are publicly traded and $200 million drawn under an unsecured credit facility. For additional information on these debts, see Note 11. Notes Payable of the Notes to Consolidated Financial Statements.

The Company was in compliance with all of the financial covenants pertaining to minimum statutory surplus, debt to total capital ratio, and risk based capital ratio under the unsecured credit facility at September 30, 2024.

E. Regulatory Capital Requirements

Among other considerations, industry and regulatory guidelines suggest that the ratio of a property and casualty insurer’s annual net premiums written to statutory policyholders’ surplus should not exceed 3.0 to 1. Based on the combined surplus of all the Insurance Companies of $1.88 billion at September 30, 2024, and net premiums written of $5.20 billion for the twelve months ended on that date, the ratio of net premiums written to surplus was 2.76 to 1 at September 30, 2024.

Item 3. Quantitative and Qualitative Disclosures About Market Risks

The Company is subject to various market risk exposures primarily due to its investing and borrowing activities. Primary market risk exposures are changes in interest rates, equity prices, and credit risk. Adverse changes to these rates and prices may occur due to changes in the liquidity of a market, or to changes in market perceptions of creditworthiness and risk tolerance. The following disclosure reflects estimates of future performance and economic conditions. Actual results may differ.
Overview
The Company’s investment policies define the overall framework for managing market and investment risks, including accountability and controls over risk management activities, and specify the investment limits and strategies that are appropriate given the liquidity, surplus, product profile, and regulatory requirements of the subsidiaries. Executive oversight of investment activities is conducted primarily through the Company’s investment committee. The Company’s investment committee focuses on strategies to enhance after-tax yields, mitigate market risks, and optimize capital to improve profitability and returns.
The Company manages exposures to market risk through the use of asset allocation, duration, and credit ratings. Asset allocation limits place restrictions on the total amount of funds that may be invested within an asset class. Duration limits on the fixed maturity securities portfolio place restrictions on the amount of interest rate risk that may be taken. Comprehensive day-to-day management of market risk within defined tolerance ranges occurs as portfolio managers buy and sell within their respective markets based upon the acceptable boundaries established by investment policies.

Credit Risk

Credit risk results from uncertainty in a counterparty’s ability to meet its obligations. Credit risk is managed by maintaining a high credit quality fixed maturity securities portfolio. As of September 30, 2024, the estimated weighted-average credit quality rating of the fixed maturity securities portfolio was A+, at fair value, consistent with the average rating at December 31, 2023.

The following table presents fixed maturity municipal securities by state in descending order of holdings at fair value at September 30, 2024:

At September 30, 2024, the fixed maturity municipal securities portfolio was broadly diversified among the states and the largest holdings were in populous states such as Florida and Texas. These holdings were further diversified primarily among cities, counties, schools, public works, hospitals, and state general obligations. The Company seeks to minimize overall credit risk and ensure diversification by limiting exposure to any particular issuer.

Taxable fixed maturity securities represented 53.0% of the Company’s total fixed maturity securities portfolio at fair value at September 30, 2024. 4.7% of the Company’s taxable fixed maturity securities at fair value were comprised of U.S. government bonds and agencies at September 30, 2024. 0.2% of the Company’s taxable fixed maturity securities at fair value, representing 0.1% of its total fixed maturity securities portfolio at fair value, were rated below investment grade at September 30, 2024. Below investment grade issues are considered “watch list” items by the Company, and their status is evaluated within the context of the Company’s overall portfolio and its investment policy on an aggregate risk management basis, as well as their ability to recover their investment on an individual issue basis.

Equity Price Risk
Equity price risk is the risk that the Company will incur losses due to adverse changes in equity markets.

42
At September 30, 2024, the Company’s primary objective for common equity investments was current income. The fair value of the equity investments consisted of $734.2 million in common stocks, $47.4 million in non-redeemable preferred stocks, and $89.3 million in private equity funds. Common stocks are typically valued for future economic prospects as perceived by the market.
Common stocks represented 12.2% of total investments at fair value at September 30, 2024. Beta is a measure of a security’s systematic (non-diversifiable) risk, which is measured by the percentage change in an individual security’s return for a 1% change in the return of the market.
Based on hypothetical reductions in the overall value of the stock market, the following table illustrates estimated reductions in the overall value of the Company’s common stock portfolio at September 30, 2024 and December 31, 2023:
September 30, 2024December 31, 2023
(Amounts in thousands, except average Beta)
Average Beta0.86 0.87 
Hypothetical reduction of 25% in the overall value of the stock market $157,853 $129,742 
Hypothetical reduction of 50% in the overall value of the stock market $315,705 $259,483 

Interest Rate Risk

Interest rate risk is the risk that the Company will incur a loss due to adverse changes in interest rates relative to the interest rate characteristics of interest bearing assets and liabilities. The Company faces interest rate risk as it invests a substantial amount of funds in interest sensitive assets and holds interest sensitive liabilities. Interest rate risk includes risks related to changes in U.S. Treasury yields and other key benchmarks, as well as changes in interest rates resulting from widening credit spreads and credit exposure to collateralized securities.
The fixed maturity securities portfolio, which represented 80.7% of total investments at September 30, 2024 at fair value, is subject to interest rate risk. The change in market interest rates is inversely related to the change in the fair value of the fixed maturity securities portfolio. A common measure of the interest sensitivity of fixed maturity securities is modified duration, a calculation that utilizes maturity, coupon rate, yield and call terms to calculate an average age to receive the present value of all the cash flows produced by such assets, including reinvestment of interest. The longer the duration, the more sensitive the asset is to market interest rate fluctuations.
The Company has historically invested in fixed maturity securities with a goal of maximizing after-tax yields and holding assets to the maturity or call date. Since assets with longer maturities tend to produce higher current yields, the Company’s historical investment philosophy resulted in a portfolio with a moderate duration. Fixed maturity securities purchased by the Company typically have call options attached, which further reduce the duration of the asset as interest rates decline. The modified duration of the overall fixed maturity securities portfolio reflecting anticipated early calls was 3.0 years at each of September 30, 2024 and December 31, 2023.

If interest rates were to rise by 100 and 200 basis points, the Company estimates that the fair value of its fixed maturity securities portfolio at September 30, 2024 would decrease by $154.7 million and $309.4 million, respectively. Conversely, if interest rates were to decrease, the fair value of the Company’s fixed maturity securities portfolio would rise, and it may cause a higher number of the Company's fixed maturity securities to be called away. The proceeds from the called fixed maturity securities would likely be reinvested at lower yields, which would result in lower overall investment income for the Company.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures designed to ensure that information required to be disclosed in the Company’s reports filed under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and that such information is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost benefit relationship of possible controls and procedures.
43
As required by Securities and Exchange Commission Rule 13a-15(b), the Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of the end of the quarter covered by this Quarterly Report on Form 10-Q. Based on the foregoing, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective at the reasonable assurance level.
Changes in Internal Control over Financial Reporting

There has been no change in the Company’s internal control over financial reporting during the Company’s most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. The Company’s process for evaluating controls and procedures is continuous and encompasses constant improvement of the design and effectiveness of established controls and procedures and the remediation of any deficiencies which may be identified during this process.

PART II - OTHER INFORMATION
 
Item 1. Legal Proceedings

The Company is, from time to time, named as a defendant in various lawsuits or regulatory actions incidental to its insurance business. The majority of lawsuits brought against the Company relate to insurance claims that arise in the normal course of business and are reserved for through the reserving process. For a discussion of the Company’s reserving methods, see the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.
The Company establishes reserves for non-insurance claims related lawsuits, regulatory actions, and other contingencies when the Company believes a loss is probable and is able to estimate its potential exposure. For loss contingencies believed to be reasonably possible, the Company also discloses the nature of the loss contingency and an estimate of the possible loss, range of loss, or a statement that such an estimate cannot be made. In addition, the Company accrues for anticipated legal defense costs associated with such lawsuits and regulatory actions. While actual losses may differ from the amounts recorded and the ultimate outcome of the Company's pending actions is generally not yet determinable, the Company does not believe that the ultimate resolution of currently pending legal or regulatory proceedings, either individually or in the aggregate, will have a material adverse effect on its financial condition or cash flows.
In all cases, the Company vigorously defends itself unless a reasonable settlement appears appropriate.

Exhibit 15.1
Report of Independent Registered Public Accounting Firm
To the Board of Directors and Shareholders
Mercury General Corporation:

Results of Review of Interim Financial Information
We have reviewed the consolidated balance sheet of Mercury General Corporation and subsidiaries (the Company) as of September 30, 2024, the related consolidated statements of operations and shareholders' equity for the three-month and nine-month periods ended September 30, 2024 and 2023, the related consolidated statements of cash flows for the nine-month periods ended September 30, 2024 and 2023, and the related notes (collectively, the consolidated interim financial information). Based on our reviews, we are not aware of any material modifications that should be made to the consolidated interim financial information for it to be in conformity with U.S. generally accepted accounting principles.
We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2023, and the related consolidated statements of operations, shareholders’ equity, and cash flows for the year then ended (not presented herein); and in our report dated February 13, 2024, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated balance sheet as of December 31, 2023, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.
Basis for Review Results
This consolidated interim financial information is the responsibility of the Company’s management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our reviews in accordance with the standards of the PCAOB. A review of consolidated interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Organization, Consolidation and Presentation of Financial Statements [Abstract]  
General General
Consolidation and Basis of Presentation
The interim consolidated financial statements include the accounts of Mercury General Corporation and its subsidiaries (referred to herein collectively as the “Company”). For the list of the Company’s subsidiaries, see Note 1. Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. These interim financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”), which differ in some respects from those filed in reports to insurance regulatory authorities. The financial data of the Company included herein are unaudited. In the opinion of management, all material adjustments of a normal recurring nature have been made to present fairly the Company’s financial position at September 30, 2024 and the results of operations and cash flows for the periods presented. All intercompany transactions and balances have been eliminated.

Certain financial information that is normally included in annual financial statements prepared in accordance with GAAP, but that is not required for interim reporting purposes, has been omitted from the accompanying interim consolidated financial statements and related notes. Readers are urged to review the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 for more complete descriptions and discussions. Operating results and cash flows for the nine months ended September 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024.

Certain prior period amounts have been reclassified to conform to the current period presentation.

Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates require the Company to apply complex assumptions and judgments, and often the Company must make estimates about the effects of matters that are inherently uncertain and will likely change in subsequent periods. The most significant assumptions in the preparation of these consolidated financial statements relate to reserves for losses and loss adjustment expenses ("LAE"). Actual results could differ from those estimates. See Note 1. Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.
Earnings (Loss) per Share
There were no potentially dilutive securities with anti-dilutive effect for the three and nine months ended September 30, 2024. Potentially dilutive securities representing 17,500 shares of common stock were excluded from the computation of diluted loss per share for the three and nine months ended September 30, 2023, because their effect would have been anti-dilutive.
Dividends per Share
The Company declared and paid a dividend per share of $0.3175 during each of the three-month periods ended September 30, 2024 and 2023, and dividends per share of $0.9525 during each of the nine-month periods ended September 30, 2024 and 2023.
Deferred Policy Acquisition Costs
Deferred policy acquisition costs consist of commissions paid to outside agents, premium taxes, salaries, and certain other underwriting costs that are incremental or directly related to the successful acquisition of new and renewal insurance contracts and are amortized over the life of the related policy in proportion to premiums earned. Deferred policy acquisition costs are limited to the amount that will remain after deducting from unearned premiums and anticipated investment income, the estimated losses and loss adjustment expenses, and the servicing costs that will be incurred as premiums are earned. The Company’s deferred policy acquisition costs are further limited by excluding those costs not directly related to the successful acquisition of insurance contracts. Deferred policy acquisition cost amortization was $230.3 million and $181.6 million for the three months ended September 30, 2024 and 2023, respectively, and $630.0 million and $518.8 million for the nine months ended September 30, 2024 and 2023, respectively. The Company does not defer advertising expenditures but expenses them as
incurred. The Company recorded net advertising expense of approximately $6.5 million and $2.4 million for the three months ended September 30, 2024 and 2023, respectively, and $13.8 million and $6.6 million for the nine months ended September 30, 2024 and 2023, respectively.

Fixed Assets

An office building located in Oklahoma City, Oklahoma was initially classified as a property held for sale at April 30, 2024, and $3.4 million of the property held for sale, which represented the estimated fair value of the property less the estimated costs to sell, as adjusted for changes in those estimates after the initial held-for-sale classification, was included in other assets in the Company's consolidated balance sheets until completion of the sale. A loss of $0.3 million and $1.0 million recognized as a result of the held-for-sale classification was included in other revenues in the Company's consolidated statements of operations for the three and nine months ended September 30, 2024, respectively. The Company completed the sale of this property in September 2024 for a total sale price of $3.6 million, and recognized an additional loss of $0.1 million at closing of the sale, which is included in other revenues in the Company's consolidated statements of operations for the three and nine months ended September 30, 2024. In connection with the sale of the property, the Company entered into a lease agreement whereby the Company leased 5,000 square feet of office space, or approximately 5% of the total space of the property sold, from the new owner of the property. The lease commenced in September 2024 and expires at December 31, 2024, and the monthly base rent is approximately $8,000.

The Company completed the sale of another office building located in Brea, California in September 2024 for a total sale price of $31.5 million, and recognized a gain of $20.3 million associated with the sale, which is included in other revenues in the Company's consolidated statements of operations for the three and nine months ended September 30, 2024. $21.4 million of the total sale price was received in the form of a promissory note. $9.3 million of the total sale price, after settlement of selling expenses and outstanding amounts due on the property, was received in cash. Only the cash received on the sale of the property is included in the Company's consolidated statements of cash flows for the nine months ended September 30, 2024. The note receivable is secured by the property sold and bears interest at an annual rate of 7.0%. The term of the note receivable is 4 years and interest is paid in quarterly installments. This office building was initially classified as a property held for sale at September 30, 2023, and $10.5 million of the property held for sale, which represented the carrying amount of the property, was included in other assets in the Company's consolidated balance sheets until completion of the sale.

An office building located in Folsom, California was classified as a property held for sale at June 30, 2024, and $10.0 million of the property held for sale, which represented the estimated fair value of the property less the estimated costs to sell, was included in other assets in the Company's consolidated balance sheets at September 30, 2024. A loss of $5.4 million recognized as a result of the held-for-sale classification was included in other revenues in the Company's consolidated statements of operations for the nine months ended September 30, 2024.

In addition, a parcel of land located in Rancho Cucamonga, California was classified as a property held for sale at June 30, 2024, and $1.7 million of the property held for sale, which represented the carrying amount of the property, was included in other assets in the Company's consolidated balance sheets at September 30, 2024.

The Company is actively engaged in selling these real estate properties as most of its employees currently work from home and these properties are being used on a limited basis.

Reinsurance

Unearned premiums and loss and loss adjustment expense reserves are stated in the accompanying consolidated financial statements before deductions for ceded reinsurance. Unearned premiums and loss and loss adjustment expense reserves that are ceded to reinsurers are carried in other assets and reinsurance recoverables, respectively, in the Company's consolidated balance sheets. Earned premiums and losses and loss adjustment expenses are stated net of deductions for ceded reinsurance.
The Company is the assuming reinsurer under a Catastrophe Participation Reinsurance Contract (the "Contract") effective through December 31, 2025. The Company reimburses up to $30 million in losses for a proportional share of a portfolio of catastrophe losses under the Contract, to the extent the actual loss ratio exceeds the threshold loss ratio of 73.5%. If the actual loss ratio is less than the threshold loss ratio, the Company is eligible to receive a certain portion of the underwriting profit.

The Company is party to a Catastrophe Reinsurance Treaty (the "Treaty") covering a wide range of perils that is effective through June 30, 2025. The Treaty provides $1,290 million of coverage on a per occurrence basis after covered catastrophe losses exceed the $150 million Company retention limit. The Treaty specifically excludes coverage for any Florida business and for California earthquake losses on fixed property policies, such as homeowners, but does cover losses from fires following an
earthquake. The Treaty provides for one full reinstatement of coverage limits with a minor exception at a certain upper layer of coverage, and includes some additional minor territorial and coverage restrictions.

The effect of reinsurance on property and casualty premiums written and earned was as follows:

The Company recognized ceded premiums earned of approximately $42.4 million and $30.9 million for the three months ended September 30, 2024 and 2023, respectively, and $104.9 million and $78.1 million for the nine months ended September 30, 2024 and 2023, respectively, which are included in net premiums earned in its consolidated statements of operations. The Company recognized ceded losses and loss adjustment expenses of approximately $(1.5) million and $(0.3) million for the three months ended September 30, 2024 and 2023, respectively, and $(2.5) million and $3.8 million for the nine months ended September 30, 2024 and 2023, respectively, which are included in losses and loss adjustment expenses in its consolidated statements of operations.

The Company's insurance subsidiaries, as primary insurers, are required to pay losses to the extent reinsurers are unable to discharge their obligations under the reinsurance agreements.

Revenue from Contracts with Customers (Topic 606)

The Company's revenue from contracts with customers is commission income earned from third-party insurers by its 100% owned insurance agencies, which amounted to approximately $6.4 million and $5.2 million, with related expenses of $3.2 million and $2.7 million, for the three months ended September 30, 2024 and 2023, respectively, and $18.0 million and $15.0 million, with related expenses of $9.6 million and $8.2 million, for the nine months ended September 30, 2024 and 2023, respectively. All of the commission income, net of related expenses, is included in other revenues in the Company's consolidated statements of operations, and in other income of the Property and Casualty business segment in the Company's segment reporting (see Note 13. Segment Information).

As of September 30, 2024 and December 31, 2023, the Company had no contract assets and contract liabilities, and no remaining performance obligations associated with unrecognized revenues.

Allowance for Credit Losses

Financial Instruments - Credit Losses (Topic 326) uses the "expected loss" methodology for recognizing credit losses for financial assets that are not accounted for at fair value through net income. The Company's investment portfolio, excluding accrued investment income, was not affected by Topic 326 as it applies the fair value option to all of its investments. The estimated allowance amounts for credit losses at September 30, 2024 and December 31, 2023 primarily related to premiums receivable.

Premiums Receivable

The majority of the Company's premiums receivable are short-term in nature and are due within a year, consistent with the policy term of its insurance policies sold. Generally, premiums are collected prior to providing risk coverage, minimizing the Company's exposure to credit risk. In estimating an allowance for uncollectible premiums receivable, the Company assesses
customer balances and write-offs by state, line of business, and the year the premiums were written. The estimated allowance is based on historical write-off percentages adjusted for the effects of current trends and reasonable and supportable forecasts, as well as expected recoveries of amounts written off.

The following table presents a summary of changes in allowance for credit losses on premiums receivable:

Ending balance $6,100 $5,200 $6,100 $5,200 

Accrued Interest Receivables
The Company made certain accounting policy elections for its accrued interest receivables allowed under Topic 326: a) an election to present accrued interest receivable balances separately from the associated financial assets on the balance sheet, and b) an election not to measure an allowance for credit losses on accrued interest receivable amounts and instead write off uncollectible accrued interest amounts in a timely manner by reversing interest income. The Company's accrued interest receivable balances are included in accrued investment income receivable in its consolidated balance sheets. There were no accrued interest receivable amounts considered uncollectible or written off during the nine months ended September 30, 2024 and 2023.

Accounting Standards Update and Change in Accounting Principle [Abstract]  
Recently Issued Accounting Standards Recently Issued Accounting Standards
In March 2024, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) 2024-01, "Compensation-Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards." ASU 2024-01 is intended to improve GAAP by adding an illustrative example that includes four fact patterns to demonstrate how an entity should apply the scope guidance in paragraph 718-10-15-3 to determine whether a profits interest award should be accounted for in accordance with Topic 718. The fact patterns in the illustrative example focus on the scope conditions in paragraph 718-10-15-3. The illustrative example is intended to reduce (1) complexity in determining whether a profits interest award is subject to the guidance in Topic 718 and (2) existing diversity in practice. ASU 2024-01 will be effective for the Company in the annual and interim periods beginning January 1, 2025, though early adoption is permitted. The Company is currently evaluating the impact of this ASU on its consolidated financial statements and related disclosures.

In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures." ASU 2023-09 is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in ASU 2023-09 address investor requests for enhanced income tax information primarily through changes to the rate reconciliation and income taxes paid information. ASU 2023-09 will be effective for the Company in the annual period beginning January 1, 2025, though early adoption is permitted. The Company is evaluating the presentational effect that ASU 2023-09 will have on its consolidated financial statements and expects presentation changes to its note on income taxes.

In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures." The amendments in ASU 2023-07 improve financial reporting by requiring disclosure of incremental segment information, including significant segment expenses, on an annual and interim basis for all public entities to enable investors to develop more useful financial analyses. Currently, Topic 280 requires that a public entity disclose certain information about its reportable segments. For example, a public entity is required to report a measure of segment profit or loss that the Chief Operating Decision Maker (“CODM”) uses to assess segment performance and make decisions about allocating resources. Topic 280 also requires other specified segment information, such as depreciation, amortization and depletion expense amounts, to be disclosed under certain circumstances. The amendments in ASU 2023-07 do not change or remove those disclosure requirements. The amendments in ASU 2023-07 also do not change how a public entity identifies its operating segments, aggregates those operating segments, or applies the quantitative thresholds to determine its reportable segments. The amendments in ASU 2023-07 are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of this
ASU on its consolidated financial statements and related disclosures.

In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." ASU 2020-04 provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this ASU apply only to contracts, hedging relationships, and other transactions that reference LIBOR or other interbank offered rates expected to be discontinued because of reference rate reform. ASU 2020-04 was effective for all entities as of March 12, 2020 through December 31, 2022. In December 2022, the FASB issued ASU 2022-06, "Reference Rate Reform (Topic 848), Deferral of the Sunset Date of Topic 848," which defers the sunset date of Topic 848 from December 31, 2022 to December 31, 2024. The Company does not expect any material impact on its consolidated financial statements and related disclosures resulting from applying these ASUs.

Fair Value Disclosures [Abstract]  
Financial Instruments Financial Instruments
Financial instruments recorded in the consolidated balance sheets include investments, note receivable, other receivables, options sold, accounts payable, and unsecured notes payable. Due to their short-term maturities, the carrying values of other receivables and accounts payable approximate their fair values. All investments are carried at fair value in the consolidated balance sheets.

The following table presents the fair values of financial instruments:

Notes receivable31,948 9,974 
Liabilities
Options sold620 1,955 
Notes payable571,024 557,710 
Investments
Interest and dividend income on investment holdings are recognized on an accrual basis at each measurement date and are included in net investment income in the Company’s consolidated statements of operations. The cost of investments sold is determined on a first-in and first-out method and realized gains and losses are included in net realized investment gains or losses in the Company's consolidated statements of operations.

In the normal course of investing activities, the Company either forms or enters into relationships with variable interest entities ("VIEs"). A VIE is an entity that either has investors that lack certain essential characteristics of a controlling financial interest, such as simple majority kick-out rights, or lacks sufficient funds to finance its own activities without financial support provided by other entities. The Company performs ongoing qualitative assessments of the VIEs to determine whether the Company has a controlling financial interest in the VIE and therefore is the primary beneficiary. The Company is deemed to have a controlling financial interest when it has both the ability to direct the activities that most significantly impact the economic performance of the VIE and the obligation to absorb losses or right to receive benefits from the VIE that could potentially be significant to the VIE. Based on the Company's assessment, if it determines it is the primary beneficiary, the Company consolidates the VIE in its consolidated financial statements.

From time to time, the Company forms special purpose investment vehicles to facilitate its investment activities involving derivative instruments such as total return swaps, or limited partnerships such as private equity funds. These special purpose investment vehicles are consolidated VIEs as the Company has determined it is the primary beneficiary of such VIEs. Creditors have no recourse against the Company in the event of default by these VIEs. The Company had no implied or unfunded commitments to these VIEs at September 30, 2024 and December 31, 2023. The Company's financial or other support provided to these VIEs and its loss exposure are limited to its collateral and original investment.

The Company invests, directly or indirectly through its consolidated VIEs, in limited partnerships or limited liability companies such as private equity funds. These investments are non-consolidated VIEs as the Company has determined it is not the primary beneficiary of such VIEs. The Company's maximum exposure to loss with respect to these VIEs is limited to the total carrying value that is included in equity securities in the Company's consolidated balance sheets. At each of September 30,
2024 and December 31, 2023, the Company had approximately $8 million in unfunded commitments to these VIEs.

Notes Receivable

In September 2024, the Company completed the sale of an office building located in Brea, California for a total sale price of $31.5 million. $21.4 million of the total sale price was received in the form of a promissory note. The note receivable is secured by the property sold, and bears interest at an annual rate of 7.0%. The term of the note receivable is four years and interest is paid in quarterly installments.

In March 2023, the Company completed the sale of an office building located in Clearwater, Florida, for a total sale price of approximately $19.6 million. $9.8 million of the total sale price was received in the form of a promissory note. The note receivable is secured by the property sold, and bears interest at an annual rate of 7.0% for the first two years, with an adjustment to the greater of 7.0% or the rate on a one-year U.S. Treasury Bill at the two-year anniversary for the remainder of the term. The term of the note receivable is four years and interest is paid in monthly installments.

Interest earned on the notes receivable is recognized in other revenues in the Company's consolidated statements of operations. The Company elected to apply the fair value option to the notes receivable at the time they were first recognized. The fair values of the notes receivable are included in other assets in the Company's consolidated balance sheets, while the changes in fair value of the notes receivable are included in net realized investment gains or losses in the Company's consolidated statements of operations.

Options Sold
The Company writes covered call options through listed and over-the-counter exchanges. When the Company writes an option, an amount equal to the premium received by the Company is recorded as a liability and is subsequently adjusted to the current fair value of the option written. Premiums received from writing options that expire unexercised are treated by the Company as realized gains from investments on the expiration date. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security or currency in determining whether the Company has realized a gain or loss. The Company, as writer of an option, bears the market risk of an unfavorable change in the price of the security underlying the written option. Liabilities for covered call options are included in other liabilities in the Company's consolidated balance sheets.

Notes Payable
The fair values of the Company’s publicly traded $375 million unsecured notes at September 30, 2024 and December 31, 2023 and its $200 million drawn under the unsecured credit facility at September 30, 2024 and December 31, 2023 were obtained from a third party pricing service.

The Company applies the fair value option to all fixed maturity and equity investment securities, short-term investments, and notes receivable. The primary reasons for electing the fair value option were simplification and cost-benefit considerations as well as the expansion of the use of fair value measurement by the Company consistent with the long-term measurement objectives of the FASB for accounting for financial instruments.

Gains or losses due to changes in fair value of financial instruments measured at fair value pursuant to application of the fair value option are included in net realized investment gains or losses in the Company’s consolidated statements of operations.

Fair Value Measurement

Financial Instruments, Financial Assets, Balance Sheet Groupings [Abstract]  
Fair Value Measurement Fair Value Measurements
The Company employs a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date using the exit price. Accordingly, when market observable data are not readily available, the Company’s own assumptions are used to reflect those that market participants would be presumed to use in pricing the asset or liability at the measurement date.

Assets and liabilities recorded at fair value on the consolidated balance sheets are categorized based on the level of judgment associated with inputs used to measure their fair values and the level of market price observability, as follows:

Level 1Unadjusted quoted prices are available in active markets for identical assets or liabilities as of the reporting date.
Level 2
Pricing inputs are other than quoted prices in active markets, which are based on the following:
 
•     Quoted prices for similar assets or liabilities in active markets;
 
•     Quoted prices for identical or similar assets or liabilities in non-active markets; or
 
•     Either directly or indirectly observable inputs as of the reporting date.
Level 3Pricing inputs are unobservable and significant to the overall fair value measurement, and the determination of fair value requires significant management judgment or estimation.

In certain cases, inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. Thus, a Level 3 fair value measurement may include inputs that are observable (Level 1 or Level 2) and unobservable (Level 3). The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and consideration of factors specific to the asset or liability.

The Company uses prices and inputs that are current as of the measurement date, including during periods of market disruption. In periods of market disruption, the ability to observe prices and inputs may be reduced for many instruments. This condition could cause an instrument to be reclassified from Level 1 to Level 2, or from Level 2 to Level 3. The Company recognizes transfers between levels at either the actual date of the event or a change in circumstances that caused the transfer.

Summary of Significant Valuation Techniques for Financial Assets and Financial Liabilities
The Company’s fair value measurements are based on the market approach, which utilizes market transaction data for the same or similar instruments. The Company obtained unadjusted fair values on 98.5% of its investment portfolio at fair value from an independent pricing service at September 30, 2024.

Level 1 measurements - Fair values of financial assets and financial liabilities are obtained from an independent pricing service, and are based on unadjusted quoted prices for identical assets or liabilities in active markets. Additional pricing services and closing exchange values are used as a comparison to ensure that reasonable fair values are used in pricing the investment portfolio.
U.S. government bonds and agencies /Short-term bonds: Valued using unadjusted quoted market prices for identical assets in
active markets.
Common stock: Comprised of actively traded, exchange listed U.S. and international equity securities and valued based on unadjusted quoted prices for identical assets in active markets.
Money market instruments: Valued based on unadjusted quoted prices for identical assets in active markets.
Options sold: Comprised of free-standing exchange listed derivatives that are actively traded and valued based on unadjusted quoted prices for identical instruments in active markets.
Level 2 measurements - Fair values of financial assets and financial liabilities are obtained from an independent pricing service or outside brokers, and are based on prices for similar assets or liabilities in active markets or valuation models whose inputs are observable, directly or indirectly, for substantially the full term of the asset or liability. Additional pricing services are used as a comparison to ensure reliable fair values are used in pricing the investment portfolio.
Municipal securities: Valued based on models or matrices using inputs such as quoted prices for identical or similar assets in active markets.
Mortgage-backed securities: Comprised of securities that are collateralized by residential and commercial mortgage loans valued based on models or matrices using multiple observable inputs, such as benchmark yields, reported trades and broker/dealer quotes, for identical or similar assets in active markets. The Company had holdings of $28.2 million and $33.0 million at fair value in commercial mortgage-backed securities at September 30, 2024 and December 31, 2023, respectively.

Corporate securities/Short-term bonds: Valued based on a multi-dimensional model using multiple observable inputs, such as benchmark yields, reported trades, broker/dealer quotes and issue spreads, for identical or similar assets in active markets.
Non-redeemable preferred stock: Valued based on observable inputs, such as underlying and common stock of same issuer and appropriate spread over a comparable U.S. Treasury security, for identical or similar assets in active markets.
Collateralized loan obligations ("CLOs"): Valued based on underlying debt instruments and the appropriate benchmark spread for similar assets in active markets.
Other asset-backed securities: Comprised of securities that are collateralized by non-mortgage assets, such as automobile loans, valued based on models or matrices using multiple observable inputs, such as benchmark yields, reported trades and broker/dealer quotes, for identical or similar assets in active markets.
Notes receivable: Valued based on observable inputs, such as benchmark yields, and considering any premium or discount for the differential between the stated interest rate and market interest rates, based on quoted market prices of similar instruments.
Level 3 measurements - Fair values of financial assets and financial liabilities are based on inputs that are both unobservable and significant to the overall fair value measurement, including any items in which the evaluated prices obtained elsewhere are deemed to be of a distressed trading level. At September 30, 2024 and December 31, 2023, the Company did not have any financial assets or financial liabilities based on Level 3 measurements.
Fair value measurement using NAV practical expedient - The fair value of the Company's investment in private equity funds measured at net asset value ("NAV") is determined using NAV as advised by the external fund managers and the third party administrators. The NAV of the Company's limited partnership or limited liability company interest in such a fund is based on the manager's and the administrator's valuation of the underlying holdings in accordance with the fund's governing documents and GAAP. In accordance with applicable accounting guidance, private equity funds measured at fair value using the NAV practical expedient are not classified in the fair value hierarchy. At September 30, 2024, the Company had capital invested in four such funds: the strategy of three such funds with a combined fair value of approximately $85.5 million at September 30, 2024 is to provide current income to investors by investing mainly in secured loans, CLOs or CLO issuers (including CLO equity and CLO mezzanine tranches), and equity interests in vehicles established to purchase and warehouse loans; the strategy of the other such fund with a fair value of approximately $3.7 million at September 30, 2024 is to achieve long-term capital appreciation through privately-negotiated venture capital investments in seed- and early-stage portfolio companies with technology-enabled business models. The Company had approximately $8 million in unfunded commitments at September 30, 2024 with respect to the private equity funds measured at NAV. The underlying assets of the funds are expected to be liquidated over the period of approximately one year to eight years from September 30, 2024. In addition, the Company does not have the ability to redeem or withdraw from the funds, or to sell, assign, pledge or transfer its investment, without the consent from the General Partner or Managers of the funds. The Company will receive distributions based on the liquidation of the underlying assets and the interest proceeds from the underlying assets for all the funds.
The Company’s financial instruments at fair value are reflected in the consolidated balance sheets on a trade-date basis. Related unrealized gains or losses are recognized in net realized investment gains or losses in the consolidated statements of operations. Fair value measurements are not adjusted for transaction costs.

The following tables present information about the Company’s assets and liabilities measured at fair value on a recurring basis, and indicate the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair values:

Share-Based Compensation

Share-Based Payment Arrangement, Recognized Amount [Abstract]  
Share-Based Compensation Share-Based Compensation
In February 2015, the Company's Board of Directors (the "Board") adopted the 2015 Incentive Award Plan (the "2015 Plan"), replacing the 2005 Equity Incentive Plan which expired in January 2015. The 2015 Plan was approved at the Company's Annual Meeting of Shareholders in May 2015. A maximum of 4,900,000 shares of common stock are authorized for issuance under the 2015 Plan, with 4,830,000 shares of common stock available for future grant as of September 30, 2024 upon exercise of stock options, stock appreciation rights and other awards, or upon vesting of restricted stock unit ("RSU") or deferred stock awards.

In February 2024, the Board adopted the 2024 Long-Term Incentive Plan (the “LTIP”) to provide certain key employees with the right to receive cash awards providing an opportunity to participate in the appreciation of the Company’s value and in order to retain these key employees and reward them for contributing to the success of the Company. Participants in the LTIP
may be granted a number of notional interests, or phantom stock units ("PSUs"). Each PSU represents the right to receive payment of the value of a share of the Company’s common stock upon vesting. PSUs may be granted subject to vesting conditions, which may include service-based and/or performance-based vesting conditions tied to corporate and/or individual achievement objectives. An employee must remain employed through the date of payment of an award to be eligible for any payout under the LTIP. These PSUs are settled in cash upon vesting and accounted for as liability-based awards.

Stock Options

In February 2018, the Compensation Committee of the Board awarded a total of 80,000 stock options to four senior executives under the 2015 Plan, which vested over the four-year requisite service period and had a term of ten years from the date of grant, except for 10,000 of these stock options that were forfeited in February 2019 following the departure of a senior executive. The fair values of these stock options were estimated on the date of grant using a closed-form option valuation model (Black-Scholes).
As of September 30, 2024, 17,500 of the total stock options awarded and vested under the 2015 Plan have not been exercised, each with a remaining term of approximately 3.4 years.
Performance-based PSUs
During the nine months ended September 30, 2024, the Company granted a total "target" award of 200,532 performance-based PSUs to certain executive officers and other key employees of the Company, 3,016 of which were forfeited because the recipients were no longer employed by the Company. The payout value of the performance-based PSUs granted under the LTIP will be determined based on the achievement of specific, pre-established corporate performance objectives, and in part on individual performance, during the applicable three-year performance period (the "Performance Cycle"). The maximum payout level for the performance-based PSUs is 150% of the “target” award.
The following table presents the summary of the performance-based PSU grants as of September 30, 2024:
    
Grant year2024
Three-year performance period ending December 31,
2026
Vesting shares, target (net of forfeited)197,516
Vesting shares, maximum (net of forfeited)296,274

These performance-based PSUs vest at the end of the Performance Cycle beginning with the year of the grant, and then only if, and to the extent that, the Company’s performance during the Performance Cycle achieves the threshold established by the Compensation Committee of the Board. Each annual performance result is determined based on the average of the Company’s annual market share growth and its annual combined ratio. The vested number of performance-based PSUs for each grantee is based on the average of the Company's three annual performance results combined with the individual's performance during the Performance Cycle. The cash payout amount for each unit of the vested performance-based PSUs is equal to the average closing price per share of the Company’s common stock for the 30 calendar days preceding the determination of the final number of vested PSUs for each grantee at the end of the Performance Cycle.

Liabilities for the expected cash payout and associated compensation expenses are recognized based on management’s best estimate of the number of the performance-based PSUs expected to be vested resulting from the probable outcome of the performance-based vesting conditions, combined with the market price of the Company's common stock at the end of each reporting period. If the performance-based vesting conditions are not expected to be met for the Performance Cycle, no compensation cost will be recognized and any recognized compensation cost will be reversed.
Restricted PSUs

The Company, from time to time, grants restricted PSUs to certain key employees, typically to retain such key employees. The restricted PSUs vest in three equal annual installments on each of the first three anniversaries of the grant date. The payout value of the restricted PSUs granted under the LTIP will be determined based on the closing price per share of the Company's common stock at each vesting date. The vested amount of the restricted PSUs is paid at the end of each annual vesting period. During the nine months ended September 30, 2024, the Company granted a total of 25,102 restricted PSUs to certain key employees of the Company, 726 of which were forfeited because the recipients were no longer employed by the Company.
The Company recorded approximately $1.5 million and $3.2 million of share-based compensation expense associated with the performance-based and restricted PSUs for the three and nine months ended September 30, 2024, respectively, which are included in other operating expenses in its consolidated statements of operations.

Components of Income Tax Expense (Benefit), Continuing Operations [Abstract]  
Income Taxes Income Taxes
For financial statement purposes, the Company recognizes tax benefits related to positions taken, or expected to be taken, on a tax return only if the positions are “more-likely-than-not” sustainable. Once this threshold has been met, the Company’s measurement of its expected tax benefits is recognized in its consolidated financial statements.

The total amount of unrecognized tax benefits related to tax uncertainties decreased by approximately $2.3 million during the nine months ended September 30, 2024, primarily resulting from the payment of the assessed amount related to a California Franchise Tax Board audit for tax year 2011, which has now been resolved with no outstanding issues.

The Company and its subsidiaries file income tax returns with the Internal Revenue Service and the taxing authorities of various states. Tax years that remain subject to examination by major taxing jurisdictions are 2021 through 2023 for federal taxes and 2020 through 2023 for state taxes.

Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial reporting basis and the respective tax basis of the Company’s assets and liabilities, and expected benefits of utilizing net operating loss, capital loss, and tax-credit carryforwards. The Company assesses the likelihood that its deferred tax assets will be realized and, to the extent management does not believe these assets are more likely than not to be realized, a valuation allowance is established. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates or laws is recognized in net income (loss) in the period that includes the enactment date.

At September 30, 2024, the Company’s deferred income taxes were in a net asset position, which included a combination of ordinary and capital deferred tax expenses or benefits. In assessing the Company’s ability to realize deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon generating sufficient taxable income of the appropriate character within the carryback and carryforward periods available under the tax law. Management considers the reversal of deferred tax liabilities, projected future taxable income of an appropriate nature, and tax planning strategies in making this assessment. The Company believes that through projected future taxable income of an appropriate nature, the use of prudent tax planning strategies, and the generation of capital gains, sufficient income will be realized in order to maximize the full benefits of its deferred tax assets. Although realization is not assured, management believes that it is more likely than not that the Company’s deferred tax assets will be realized.

Gross reserves, end of period$3,073,690 $2,723,776 
The increase in the provision for insured events of prior years during the nine months ended September 30, 2024 of $16.5 million was primarily attributable to higher than estimated losses and loss adjustment expenses in the commercial automobile and commercial property lines of insurance business and catastrophe losses, partially offset by favorable development in the private passenger automobile and homeowners lines of insurance business. The decrease in the provision for insured events of prior years during the nine months ended September 30, 2023 of $32.1 million was primarily attributable to lower than estimated losses and loss adjustment expenses in the private passenger automobile and homeowners lines of insurance business, partially offset by unfavorable development in the commercial property line of insurance business.

For the nine months ended September 30, 2024 and 2023, the Company incurred catastrophe losses net of reinsurance of approximately $236 million and $223 million, respectively. The majority of 2024 catastrophe losses resulted from tornadoes, hailstorms and convective storms in Texas and Oklahoma, winter storms and rainstorms in California, and the impact of Hurricane Helene in Florida and Georgia. The majority of 2023 catastrophe losses resulted from winter storms and rainstorms in California, Texas and Oklahoma, and the impact of Hurricane Hilary in California. The Company experienced unfavorable development of approximately $7 million and favorable development of approximately $4 million on prior years' catastrophe losses for the nine months ended September 30, 2024 and 2023, respectively.

__________ 
(1)On March 8, 2017, the Company completed a public debt offering issuing $375 million of senior notes. The notes are unsecured, senior obligations of the Company with a 4.4% annual coupon payable on March 15 and September 15 of each year commencing September 15, 2017. The Company used the proceeds from the notes to pay off amounts outstanding under the existing loan and credit facilities and for general corporate purposes. The Company incurred debt issuance costs of approximately $3.4 million, inclusive of underwriters' fees. The notes were issued at a slight discount of 99.847% of par, resulting in the effective annualized interest rate, including debt issuance costs, of approximately 4.45%.
(2)On March 31, 2021, the Company entered into an unsecured $75 million five-year revolving credit facility. On November 18, 2022, the Company entered into the First Amendment to this credit facility. The First Amendment extended the maturity date of the loan to November 16, 2026 from March 31, 2026 with possible further extension if certain conditions are met, increased the aggregate commitments by all the lenders to $200 million from $75 million, and replaced the LIBOR with the Term SOFR. On November 30, 2023, the Company entered into the Second Amendment to this credit facility, which further increased the aggregate commitments by all the lenders to $250 million from $200 million. The interest rates on borrowings under the credit facility are based on the Company's debt to total capital ratio and range from Term SOFR plus 112.5 basis points when the ratio is under 20% to Term SOFR plus 150.0 basis points when the ratio is greater than or equal to 30%. Commitment fees for the undrawn portions of the credit facility range from 12.5 basis points when the ratio is under 20% to 22.5 basis points when the ratio is greater than or equal to 30%. The debt to total capital ratio is expressed as a percentage of (a) consolidated debt to (b) consolidated shareholders' equity plus consolidated debt. The Company's debt to total capital ratio was 23.6% at September 30, 2024, resulting in a 15.0 basis point commitment fee on any undrawn portion of the credit facility. As of October 24, 2024, a total of $200 million was drawn under this facility on a three-month revolving basis at an annual interest rate of approximately 6.47%, with $50 million available to be drawn. The Company contributed $150 million of the total amount drawn to the surplus of its consolidated insurance subsidiaries, and used the remainder for general corporate purposes.
(3)The unamortized discount and debt issuance costs are associated with the publicly traded $375 million senior unsecured notes. These are amortized to interest expense over the life of the notes, and the unamortized balance is presented in the
Company's consolidated balance sheets as a direct deduction from the carrying amount of the debt. The unamortized costs of approximately $0.7 million associated with entering into the $250 million unsecured revolving credit facility maturing on November 16, 2026 are included in other assets in the Company's consolidated balance sheets and amortized to interest expense over the term of the credit facility.

Contingencies Contingencies
The Company is, from time to time, named as a defendant in various lawsuits or regulatory actions incidental to its insurance business. The majority of lawsuits brought against the Company relate to insurance claims that arise in the normal course of business and are reserved for through the reserving process. For a discussion of the Company’s reserving methods, see the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

On September 10, 2021, the California Department of Insurance ("DOI") served the Company a Notice of Non-Compliance ("NNC"), alleging violations in connection with its 2014 Rating & Underwriting Examination Report, which was adopted by the California DOI in 2019. The NNC itemizes alleged violations, many of which management believes were corrected or otherwise resolved during the course of the examination, and seeks penalties. The Company has participated in lengthy and detailed discussions with the California DOI since the adoption of the examination report, in an attempt to address the issues deemed unresolved by the California DOI, and has taken several additional corrective actions approved by the California DOI. On August 1, 2022, the California DOI publicly announced its intention to pursue an administrative action against the Company with respect to certain outstanding issues. The Company served a written response to the NNC on September 29, 2022, along with written discovery requests. The response, consisting of a notice of defense, a motion to strike, and a motion to dismiss, challenges the NNC on procedural and substantive grounds. On November 9, 2022, the California DOI served objections and non-substantive responses to the Company's discovery requests. On November 14, 2023, the California DOI granted Consumer Watchdog's petition to intervene in the NNC, although the Company did not agree to allow its involvement in the mediation, which took place on March 4, 2024. The parties did not make any meaningful progress toward settlement, but are continuing settlement discussions. The parties are also conferring regarding the possible filing of an Amended NNC that would eliminate the resolved items and identify the remaining issues in dispute should the matter proceed to a hearing. The Company cannot reasonably predict the likelihood, timing or outcome of any hearing process or administrative action, nor can it reasonably estimate the amount of penalties, if any.

The Company establishes reserves for non-insurance claims related lawsuits, regulatory actions, and other contingencies when the Company believes a loss is probable and is able to estimate its potential exposure. For loss contingencies believed to be reasonably possible, the Company also discloses the nature of the loss contingency and an estimate of the possible loss, range of loss, or a statement that such an estimate cannot be made. In addition, the Company accrues for anticipated legal defense costs associated with such lawsuits and regulatory actions. While actual losses may differ from the amounts recorded and the ultimate outcome of the Company's pending actions is generally not yet determinable, the Company does not believe that the ultimate resolution of currently pending legal or regulatory proceedings, either individually or in the aggregate, will have a material adverse effect on its financial condition or cash flows.
In all cases, the Company vigorously defends itself unless a reasonable settlement appears appropriate. For a discussion of any additional regulatory or legal matters, see the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

Segment Reporting [Abstract]  
Segment Information Segment Information
The Company is primarily engaged in writing personal automobile insurance and provides related property and casualty insurance products to its customers through 12 subsidiaries in 11 states, principally in California.
The Company has one reportable business segment - the Property and Casualty business segment.
The Company’s CODM evaluates operating results based on pre-tax underwriting results which is calculated as net premiums earned less (a) losses and loss adjustment expenses and (b) underwriting expenses (policy acquisition costs and other operating expenses).
Expenses are allocated based on certain assumptions that are primarily related to premiums and losses. The Company’s net investment income, net realized investment gains or losses, other income, and interest expense are excluded in evaluating pretax underwriting profit. The Company does not allocate its assets, including investments, or income taxes in evaluating pre-tax underwriting profit.
Property and Casualty Lines
The Property and Casualty business segment offers several insurance products to the Company’s individual customers and small business customers. These insurance products are: private passenger automobile which is the Company’s primary business, and related insurance products such as homeowners, commercial automobile and commercial property. These related insurance products are primarily sold to the Company’s individual customers and small business customers, which increases retention of the Company’s private passenger automobile client base. The insurance products comprising the Property and Casualty business segment are sold through the same distribution channels, mainly through independent and 100% owned insurance agents, and go through a similar underwriting process.

Other Lines

The Other business segment represents net premiums written and earned from an operating segment that does not meet the quantitative thresholds required to be considered a reportable segment. This operating segment offers automobile mechanical protection warranties which are primarily sold through automobile dealerships and credit unions.

Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Consolidation and Basis of Presentation
The interim consolidated financial statements include the accounts of Mercury General Corporation and its subsidiaries (referred to herein collectively as the “Company”). For the list of the Company’s subsidiaries, see Note 1. Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. These interim financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”), which differ in some respects from those filed in reports to insurance regulatory authorities. The financial data of the Company included herein are unaudited. In the opinion of management, all material adjustments of a normal recurring nature have been made to present fairly the Company’s financial position at September 30, 2024 and the results of operations and cash flows for the periods presented. All intercompany transactions and balances have been eliminated.

Certain financial information that is normally included in annual financial statements prepared in accordance with GAAP, but that is not required for interim reporting purposes, has been omitted from the accompanying interim consolidated financial statements and related notes. Readers are urged to review the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 for more complete descriptions and discussions. Operating results and cash flows for the nine months ended September 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024.

Certain prior period amounts have been reclassified to conform to the current period presentation.
Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates require the Company to apply complex assumptions and judgments, and often the Company must make estimates about the effects of matters that are inherently uncertain and will likely change in subsequent periods. The most significant assumptions in the preparation of these consolidated financial statements relate to reserves for losses and loss adjustment expenses ("LAE"). Actual results could differ from those estimates. See Note 1. Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023
Earnings per Share
There were no potentially dilutive securities with anti-dilutive effect for the three and nine months ended September 30, 2024. Potentially dilutive securities representing 17,500 shares of common stock were excluded from the computation of diluted loss per share for the three and nine months ended September 30, 2023, because their effect would have been anti-dilutive.
Deferred Policy Acquisition Costs
Deferred policy acquisition costs consist of commissions paid to outside agents, premium taxes, salaries, and certain other underwriting costs that are incremental or directly related to the successful acquisition of new and renewal insurance contracts and are amortized over the life of the related policy in proportion to premiums earned. Deferred policy acquisition costs are limited to the amount that will remain after deducting from unearned premiums and anticipated investment income, the estimated losses and loss adjustment expenses, and the servicing costs that will be incurred as premiums are earned. The Company’s deferred policy acquisition costs are further limited by excluding those costs not directly related to the successful acquisition of insurance contracts. Deferred policy acquisition cost amortization was $230.3 million and $181.6 million for the three months ended September 30, 2024 and 2023, respectively, and $630.0 million and $518.8 million for the nine months ended September 30, 2024 and 2023, respectively. The Company does not defer advertising expenditures but expenses them as
incurred. The Company recorded net advertising expense of approximately $6.5 million and $2.4 million for the three months ended September 30, 2024 and 2023, respectively, and $13.8 million and $6.6 million for the nine months ended September 30, 2024 and 2023, respectively.
Reinsurance
Unearned premiums and loss and loss adjustment expense reserves are stated in the accompanying consolidated financial statements before deductions for ceded reinsurance. Unearned premiums and loss and loss adjustment expense reserves that are ceded to reinsurers are carried in other assets and reinsurance recoverables, respectively, in the Company's consolidated balance sheets. Earned premiums and losses and loss adjustment expenses are stated net of deductions for ceded reinsurance.
The Company is the assuming reinsurer under a Catastrophe Participation Reinsurance Contract (the "Contract") effective through December 31, 2025. The Company reimburses up to $30 million in losses for a proportional share of a portfolio of catastrophe losses under the Contract, to the extent the actual loss ratio exceeds the threshold loss ratio of 73.5%. If the actual loss ratio is less than the threshold loss ratio, the Company is eligible to receive a certain portion of the underwriting profit.

The Company is party to a Catastrophe Reinsurance Treaty (the "Treaty") covering a wide range of perils that is effective through June 30, 2025. The Treaty provides $1,290 million of coverage on a per occurrence basis after covered catastrophe losses exceed the $150 million Company retention limit. The Treaty specifically excludes coverage for any Florida business and for California earthquake losses on fixed property policies, such as homeowners, but does cover losses from fires following an
earthquake. The Treaty provides for one full reinstatement of coverage limits with a minor exception at a certain upper layer of coverage, and includes some additional minor territorial and coverage restrictions.

The effect of reinsurance on property and casualty premiums written and earned was as follows:

     Net$1,313,282 $1,082,979 $3,701,347 $3,107,812 

The Company recognized ceded premiums earned of approximately $42.4 million and $30.9 million for the three months ended September 30, 2024 and 2023, respectively, and $104.9 million and $78.1 million for the nine months ended September 30, 2024 and 2023, respectively, which are included in net premiums earned in its consolidated statements of operations. The Company recognized ceded losses and loss adjustment expenses of approximately $(1.5) million and $(0.3) million for the three months ended September 30, 2024 and 2023, respectively, and $(2.5) million and $3.8 million for the nine months ended September 30, 2024 and 2023, respectively, which are included in losses and loss adjustment expenses in its consolidated statements of operations.

The Company's insurance subsidiaries, as primary insurers, are required to pay losses to the extent reinsurers are unable to discharge their obligations under the reinsurance agreements.
Revenue from Contracts with Customers (Topic 606)
The Company's revenue from contracts with customers is commission income earned from third-party insurers by its 100% owned insurance agencies, which amounted to approximately $6.4 million and $5.2 million, with related expenses of $3.2 million and $2.7 million, for the three months ended September 30, 2024 and 2023, respectively, and $18.0 million and $15.0 million, with related expenses of $9.6 million and $8.2 million, for the nine months ended September 30, 2024 and 2023, respectively. All of the commission income, net of related expenses, is included in other revenues in the Company's consolidated statements of operations, and in other income of the Property and Casualty business segment in the Company's segment reporting (see Note 13. Segment Information).
As of September 30, 2024 and December 31, 2023, the Company had no contract assets and contract liabilities, and no remaining performance obligations associated with unrecognized revenues.
Allowance for Credit Losses
Financial Instruments - Credit Losses (Topic 326) uses the "expected loss" methodology for recognizing credit losses for financial assets that are not accounted for at fair value through net income. The Company's investment portfolio, excluding accrued investment income, was not affected by Topic 326 as it applies the fair value option to all of its investments. The estimated allowance amounts for credit losses at September 30, 2024 and December 31, 2023 primarily related to premiums receivable.

Premiums Receivable

The majority of the Company's premiums receivable are short-term in nature and are due within a year, consistent with the policy term of its insurance policies sold. Generally, premiums are collected prior to providing risk coverage, minimizing the Company's exposure to credit risk. In estimating an allowance for uncollectible premiums receivable, the Company assesses
customer balances and write-offs by state, line of business, and the year the premiums were written. The estimated allowance is based on historical write-off percentages adjusted for the effects of current trends and reasonable and supportable forecasts, as well as expected recoveries of amounts written off.

The following table presents a summary of changes in allowance for credit losses on premiums receivable:
 Three Months Ended September 30,Nine Months Ended September 30,

Recoveries during the period of amounts previously written off 245 126 631 405 
Ending balance $6,100 $5,200 $6,100 $5,200 
Accrued Interest Receivables The Company made certain accounting policy elections for its accrued interest receivables allowed under Topic 326: a) an election to present accrued interest receivable balances separately from the associated financial assets on the balance sheet, and b) an election not to measure an allowance for credit losses on accrued interest receivable amounts and instead write off uncollectible accrued interest amounts in a timely manner by reversing interest income. The Company's accrued interest receivable balances are included in accrued investment income receivable in its consolidated balance sheets.
Recently Issued Accounting Standards
In March 2024, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) 2024-01, "Compensation-Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards." ASU 2024-01 is intended to improve GAAP by adding an illustrative example that includes four fact patterns to demonstrate how an entity should apply the scope guidance in paragraph 718-10-15-3 to determine whether a profits interest award should be accounted for in accordance with Topic 718. The fact patterns in the illustrative example focus on the scope conditions in paragraph 718-10-15-3. The illustrative example is intended to reduce (1) complexity in determining whether a profits interest award is subject to the guidance in Topic 718 and (2) existing diversity in practice. ASU 2024-01 will be effective for the Company in the annual and interim periods beginning January 1, 2025, though early adoption is permitted. The Company is currently evaluating the impact of this ASU on its consolidated financial statements and related disclosures.

In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures." ASU 2023-09 is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in ASU 2023-09 address investor requests for enhanced income tax information primarily through changes to the rate reconciliation and income taxes paid information. ASU 2023-09 will be effective for the Company in the annual period beginning January 1, 2025, though early adoption is permitted. The Company is evaluating the presentational effect that ASU 2023-09 will have on its consolidated financial statements and expects presentation changes to its note on income taxes.

In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures." The amendments in ASU 2023-07 improve financial reporting by requiring disclosure of incremental segment information, including significant segment expenses, on an annual and interim basis for all public entities to enable investors to develop more useful financial analyses. Currently, Topic 280 requires that a public entity disclose certain information about its reportable segments. For example, a public entity is required to report a measure of segment profit or loss that the Chief Operating Decision Maker (“CODM”) uses to assess segment performance and make decisions about allocating resources. Topic 280 also requires other specified segment information, such as depreciation, amortization and depletion expense amounts, to be disclosed under certain circumstances. The amendments in ASU 2023-07 do not change or remove those disclosure requirements. The amendments in ASU 2023-07 also do not change how a public entity identifies its operating segments, aggregates those operating segments, or applies the quantitative thresholds to determine its reportable segments. The amendments in ASU 2023-07 are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of this
ASU on its consolidated financial statements and related disclosures.

In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." ASU 2020-04 provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this ASU apply only to contracts, hedging relationships, and other transactions that reference LIBOR or other interbank offered rates expected to be discontinued because of reference rate reform. ASU 2020-04 was effective for all entities as of March 12, 2020 through December 31, 2022. In December 2022, the FASB issued ASU 2022-06, "Reference Rate Reform (Topic 848), Deferral of the Sunset Date of Topic 848," which defers the sunset date of Topic 848 from December 31, 2022 to December 31, 2024. The Company does not expect any material impact on its consolidated financial statements and related disclosures resulting from applying these ASUs.

__________ 
(1)On March 8, 2017, the Company completed a public debt offering issuing $375 million of senior notes. The notes are unsecured, senior obligations of the Company with a 4.4% annual coupon payable on March 15 and September 15 of each year commencing September 15, 2017. The Company used the proceeds from the notes to pay off amounts outstanding under the existing loan and credit facilities and for general corporate purposes. The Company incurred debt issuance costs of approximately $3.4 million, inclusive of underwriters' fees. The notes were issued at a slight discount of 99.847% of par, resulting in the effective annualized interest rate, including debt issuance costs, of approximately 4.45%.
(2)On March 31, 2021, the Company entered into an unsecured $75 million five-year revolving credit facility. On November 18, 2022, the Company entered into the First Amendment to this credit facility. The First Amendment extended the maturity date of the loan to November 16, 2026 from March 31, 2026 with possible further extension if certain conditions are met, increased the aggregate commitments by all the lenders to $200 million from $75 million, and replaced the LIBOR with the Term SOFR. On November 30, 2023, the Company entered into the Second Amendment to this credit facility, which further increased the aggregate commitments by all the lenders to $250 million from $200 million. The interest rates on borrowings under the credit facility are based on the Company's debt to total capital ratio and range from Term SOFR plus 112.5 basis points when the ratio is under 20% to Term SOFR plus 150.0 basis points when the ratio is greater than or equal to 30%. Commitment fees for the undrawn portions of the credit facility range from 12.5 basis points when the ratio is under 20% to 22.5 basis points when the ratio is greater than or equal to 30%. The debt to total capital ratio is expressed as a percentage of (a) consolidated debt to (b) consolidated shareholders' equity plus consolidated debt. The Company's debt to total capital ratio was 23.6% at September 30, 2024, resulting in a 15.0 basis point commitment fee on any undrawn portion of the credit facility. As of October 24, 2024, a total of $200 million was drawn under this facility on a three-month revolving basis at an annual interest rate of approximately 6.47%, with $50 million available to be drawn. The Company contributed $150 million of the total amount drawn to the surplus of its consolidated insurance subsidiaries, and used the remainder for general corporate purposes.
(3)The unamortized discount and debt issuance costs are associated with the publicly traded $375 million senior unsecured notes. These are amortized to interest expense over the life of the notes, and the unamortized balance is presented in the
Company's consolidated balance sheets as a direct deduction from the carrying amount of the debt. The unamortized costs of approximately $0.7 million associated with entering into the $250 million unsecured revolving credit facility maturing on November 16, 2026 are included in other assets in the Company's consolidated balance sheets and amortized to interest expense over the term of the credit facility.
