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.

The Company is headquartered in Los Angeles, California and writes primarily personal automobile lines of business selling policies through a network of independent agents, 100% owned insurance agents and direct channels, in 11 states: Arizona, California, Florida, Georgia, Illinois, Nevada, New Jersey, New York, Oklahoma, Texas, and Virginia. The Company also offers homeowners, commercial automobile, commercial property, mechanical protection, fire, and umbrella insurance. Private passenger automobile lines of insurance business accounted for approximately 64% of the $4.0 billion of the Company’s direct premiums written in 2022, and approximately 82% of the private passenger automobile premiums were written in California.

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 Annual Report on Form 10-K.

2022 Financial Performance Summary

The Company’s net (loss) income for the year ended December 31, 2022 was $(512.7) million, or $(9.26) per diluted

share, compared to $247.9 million, or $4.48 per diluted share, for the same period in 2021. Included in net (loss) income was $168.4 million of pre-tax net investment income that was generated during 2022 on a portfolio of $4.9 billion, at fair value, at December 31, 2022, compared to $129.7 million of pre-tax net investment income that was generated during 2021 on a portfolio of $5.1 billion, at fair value, at December 31, 2021. Also included in net (loss) income were pre-tax net realized investment (losses) gains of $(488.1) million and $111.7 million in 2022 and 2021, respectively, and pre-tax catastrophe losses, net of reinsurance and reinstatement premiums earned, of approximately $101.3 million and $103.7 million in 2022 and 2021, respectively. Pre-tax net realized investment losses for 2022 resulted largely from the decrease in fair value of fixed maturity securities due to increases in market interest rates as well as the decrease in fair value of equity securities due to the decline in overall equity markets.

The Company continued its marketing efforts to enhance name recognition and lead generation in 2022, although it reduced the spending for advertising and marketing as part of its cost saving initiative. The Company believes that its marketing efforts, combined with its ability to maintain relatively low prices and a strong reputation, make its insurance products competitive in California and in other states.

The Company believes its thorough underwriting process gives it an advantage over its competitors. The Company’s agent relationships and underwriting and claims processes are its most important competitive advantages.

The Company’s operating results and growth have allowed it to consistently generate positive cash flow from operations, which was approximately $353 million and $502 million in 2022 and 2021, respectively. Cash flow from operations has been used to pay shareholder dividends and help support growth.

Economic and Industry Wide Factors

•Regulatory Uncertainty—The insurance industry is subject to strict state regulation and oversight and is governed by the laws of each state in which each insurance company operates. State regulators generally have substantial power and authority over insurance companies including, in some states, approving rate changes and rating factors, restricting cancellation and non-renewal of insurance policies, and establishing minimum capital and surplus requirements. In many states, insurance commissioners may emphasize different agendas or interpret existing regulations differently than previous commissioners. There is no certainty that current or future regulations and the interpretation of those regulations by insurance commissioners and the courts will not have an adverse impact on the Company.

•Cost Uncertainty—Because insurance companies pay claims after premiums are collected, the ultimate cost of an insurance policy is not known until well after the policy revenues are earned. Consequently, significant assumptions are made when establishing insurance rates and loss reserves. While insurance companies use sophisticated models and experienced actuaries to assist in setting rates and establishing loss reserves, there can be no assurance that current rates or current reserve estimates will be adequate. Furthermore, there can be no assurance that insurance regulators will approve rate increases when the Company’s actuarial analyses indicate that they are needed.

•Economic Conditions—The Company’s financial condition, results of operations, and liquidity may be negatively impacted by global, national and local economic conditions, such as recessions, increased levels of unemployment, inflation, and large fluctuations in interest rates. Further, volatility in global capital markets could adversely affect the Company’s investment portfolio. The Company is not able to predict the timing and effect of these factors, or their duration and severity.

•Inflation—The largest cost component for automobile insurers is losses, which include medical, replacement automobile parts, and labor costs. There can be significant variation in the overall increases in medical cost inflation, and it is often years after the respective fiscal period ends before sufficient claims have closed for the inflation rate to be known with a reasonable degree of certainty. Therefore, it can be difficult to establish reserves and set premium rates, particularly when actual inflation rates may be higher or lower than anticipated.

•Loss Frequency—Another component of overall loss costs is loss frequency, which is the number of claims per risk insured. Loss frequency trends are affected by many factors such as fuel prices, the economy, the prevalence of distracted driving, collision avoidance and other technology in vehicles, and stay-at-home orders issued by state and local governments due to the pandemic.

•Underwriting Cycle and Competition—The property and casualty insurance industry is highly cyclical, with alternating hard and soft market conditions. The Company believes that the automobile insurance market in most states has hardened during 2022 as insurance carriers began to increase rates reflecting high loss severity and increasing loss frequency as the country emerged from the COVID-19 pandemic. In California, market conditions in

2022 were hard as companies tightened their underwriting due to difficulty in obtaining regulatory approval for rate increases.

Technology

The Company has continued its core insurance platform modernization initiatives in 2022, and intends to complete the migration of most of its products from legacy systems to a single platform and continue to invest in the modernization of its technology and data science platforms in 2023.

Note on General Business and Economic Conditions

The outbreak of COVID-19 has had a notable impact on general economic conditions, including, but not limited to, the temporary closures of many businesses and reduced consumer spending. The Company has taken and continues to take a number of precautionary steps to safeguard its customers, business and employees from COVID-19. Most of the Company's employees have been working remotely, with only certain operationally critical employees working on site at various locations. In November 2021, the Company extended its "work-from-home" policy indefinitely under the new "Mercury's My Workplace" policy, allowing most of its employees to work from anywhere in the U.S. beginning January 2022.

The Company's automobile line of insurance business experienced a rapid drop in loss frequency in the second quarter of 2020 due to reduced driving following the outbreak of the pandemic. Since then, loss frequency has increased and is now near pre-pandemic levels. In 2022, inflationary trends accelerated to their highest level since the 1980s. Excessive inflation led to significant increases in loss severities related to vehicle repairs and bodily injuries. The COVID-19 pandemic also created more uncertainty, and the total effect on losses occurring during the COVID-19 era will not be known for several years. The Company expects more late reported claims and a prolonged settlement period. The sustained high loss severity, combined with loss frequency at near pre-pandemic levels, negatively impacted the Company's results of operations, and the Company has submitted private passenger automobile rate filings in many states requesting rate increases. In addition, the Company is taking various non-rate actions to improve profitability.

The Federal Open Market Committee started raising the federal funds rate in March 2022 as a response to inflationary pressures. The ensuing increases in market interest rates, combined with the high inflation, the supply chain and labor issues, and the Russia-Ukraine war, have placed significant strain on financial markets leading to market volatility and turmoil. The fair values of the Company's equity securities have reflected such market volatility and the fair values of its fixed maturity securities have decreased significantly as a result of increases in market interest rates during 2022. The Company believes that it will continue to have sufficient liquidity to support its business operations without the forced sale of investments, based on its existing cash and short-term investments, future cash flows from operations, and $175 million of undrawn credit in its unsecured credit facility.

The Company will continue to monitor the effects of COVID-19 and its variants, the high inflation and interest rates, the supply chain and labor issues, the Russia-Ukraine war, and the legislative relief programs, including the Inflation Reduction Act of 2022 signed into law in August 2022. The extent of these effects on the Company's business and financial results will depend largely on future developments, including the duration of the high inflation and interest rates and the war, most of which are highly uncertain and cannot be predicted.

In October 2022, the Company reduced its workforce by approximately 40 employees, and a one-time cost of approximately $3 million associated with the workforce reduction was recorded as an expense for the fourth quarter of 2022. The Company anticipates this reduction will result in ongoing annual cost savings of approximately $6 million.

B. Regulatory and Legal Matters

The process for implementing rate changes varies by state. For more detailed information related to insurance rate approval, see "Item 1. Business—Regulation."

During 2022, the Company implemented rate changes in 11 states. In California, no rate increases were approved by the California DOI for lines of insurance business that exceeded 5% of the Company's total net premiums earned in 2022.

In January 2023, the California DOI approved a 6.9% rate increase on each of MIC's and CAIC's private passenger automobile line of insurance business, which represented approximately 51% and 5%, respectively, of the Company's total net premiums earned in 2022. The Company plans to implement these rate increases in March 2023. In addition, the Company plans to file for another 6.9% rate increase with the California DOI in March 2023 on each of MIC's and CAIC's California private passenger automobile line of insurance business.

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 "Critical Accounting Estimates" below and Note 1. Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements in "Item 8. Financial Statements and Supplementary Data."

The Company also establishes accruals for estimated liabilities 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 material 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.

For a discussion of additional regulatory and legal matters, see Note 18. Commitments and Contingencies of the Notes to Consolidated Financial Statements in "Item 8. Financial Statements and Supplementary Data." In all cases, the Company vigorously defends itself unless a reasonable settlement appears appropriate.

C. 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 liability 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 looking at 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 required under state statutory accounting requirements. 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 generally analyzes 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.

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 provides 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.

There are many factors that can cause variability between the ultimate expected loss and the actual developed loss. While there are certainly other factors, the Company believes that the following three items tend to create the most variability between expected losses and actual losses.

(1) Inflation

For the Company’s California automobile lines of insurance business, total reserves are comprised of the following:

•BI reserves—approximately 70% of total reserves

•Material damage ("MD") reserves, including collision and comprehensive property damage—approximately 10% of total reserves

•Loss adjustment expense reserves—approximately 20% of total reserves.

Loss development on MD reserves is generally insignificant because MD claims are generally settled in a shorter period than BI claims. However, in periods of high rates of change in inflation rates, such as what has been experienced in late 2021 through 2022, loss development on MD reserves can be elevated for a short period of time. The majority of the loss adjustment expense reserves are estimated costs to defend BI claims, which tend to require longer periods of time to settle as compared to MD claims.

BI loss reserves are generally the most difficult to estimate because they take longer to close than other coverages. BI coverage in the Company’s policies includes injuries sustained by any person other than the insured, except in the case of uninsured or underinsured motorist BI coverage, which covers damages to the insured for BI caused by uninsured or underinsured motorists. BI payments are primarily for medical costs and general damages.

The following table presents the typical closure patterns of BI claims in the Company's California personal automobile insurance coverage:

% of Total

Claims Closed Dollars Paid

BI claims closed in the accident year reported 36% 12%

BI claims closed one year after the accident year reported 78% 50%

BI claims closed two years after the accident year reported 94% 76%

BI claims closed three years after the accident year reported 97% 88%

BI claims closed in the accident year reported are generally the smaller and less complex claims that settle for approximately $8,000 to $9,000 on average, whereas the total average settlement, once all claims are closed for a particular accident year, is approximately $17,000 to $27,000. The Company creates incurred and paid loss triangles to estimate ultimate losses utilizing historical payment and reserving patterns and evaluates the results of this analysis against its frequency and severity analysis to establish BI loss reserves. The Company adjusts development factors to account for inflation trends it sees in loss severity. As a larger proportion of claims from an accident year are settled, there emerges a higher degree of certainty for the loss reserves established for that accident year. At December 31, 2022, the accident years that are most likely to develop are the 2020 through 2022 accident years; however, it is possible that older accident years could develop as well.

In general, the Company expects that historical claims trends will continue with costs tending to increase, which is generally consistent with historical data, and therefore the Company believes that it is reasonable to expect inflation to continue. Many potential factors can affect the BI inflation rate, including changes in claims handling process, changes in statutes and regulations, the number of litigated files, increased use of medical procedures such as MRIs and epidural injections, general economic factors, timeliness of claims adjudication, vehicle safety, weather patterns, changes in the relative percentages of single- and multi-car accidents, social inflation, and gasoline prices, among other factors; however, the magnitude of the impact of such factors on the inflation rate is unknown.

The Company's automobile line of insurance business experienced a rapid drop in loss frequency in the second quarter of 2020 due to reduced driving following the outbreak of the pandemic. Since then, loss frequency has increased and is now near pre-pandemic levels. In 2022, inflationary trends accelerated to their highest level since the 1980s. Excessive inflation led to significant increases in loss severities related to vehicle repairs and bodily injuries. In addition, the COVID-19 pandemic created greater uncertainty in the reserve estimates: A greater number of large claims may emerge from the 2020, 2021 and 2022 accident years compared to the prior accident years as claimants may be reluctant to go to a medical provider due to the pandemic but subsequently seek monetary compensation to ease the economic hardship attributable to the pandemic. Based on these factors and uncertainty attributable to the pandemic and inflation, the reserve estimates for the 2020, 2021 and 2022 accident years are subject to a greater degree of variability.

The Company believes that it is reasonably possible that the California automobile BI severity could vary from recorded amounts by as much as 12%, 8% and 6% for 2022, 2021 and 2020 accident years, respectively; however, the variation could be more or less than these amounts.

During the years 2018 through 2022, the changes in the loss severity amounts for the three preceding accident years from the prior year amounts (BI severity variance from prior year) have ranged as follows:

High Low

Immediate preceding accident year 7.9% (2.9)%

Second preceding accident year 7.5% 0.1%

Third preceding accident year 5.2% (1.0)%

The following table presents the effects on the California automobile BI loss reserves for the 2022, 2021 and 2020 accident years based on possible variations in the severity recorded; however, the actual variations could be more or less than these amounts:

___________

(1) Implied inflation rate is calculated by dividing the difference between the current and prior year actual recorded severity by

the prior year actual recorded severity. The Company believes that severity increases are caused by litigation, medical costs, inflation, and increased utilization of medical procedures.

(2) In 2022, inflationary trends accelerated to their highest level since the 1980s, which had a significant impact on medical expenses for bodily injuries. Bodily injury costs were also under pressure from social inflation. These inflationary factors led to an increase in loss severity in 2022.

(2) Claim Count Development

The Company generally estimates ultimate claim counts for an accident period based on development of claim counts in prior accident periods. Typically, almost every claim is reported within one year following the end of an accident year and at that point the Company has a high degree of certainty as to the ultimate claim count. There are many factors that can affect the number of claims reported after an accident period ends. These factors include changes in weather patterns, a change in the number of litigated files, the number of automobiles insured, and whether the last day of the accident period falls on a weekday or a weekend. However, the Company is unable to determine which, if any, of the factors actually impact the number of claims reported and, if so, by what magnitude.

The COVID-19 pandemic created greater uncertainty in the claims count development for the 2020, 2021 and 2022 accident years. The Company believes that the reduced services for non-critical cases at medical facilities and fear of infection during the pandemic combined with the economic hardship caused by the pandemic are likely to increase the late reporting of claims seeking settlement for monetary compensation. At December 31, 2022, there were 19,589 California automobile BI claims reported for the 2022 accident year and the Company estimates that these are expected to ultimately grow by approximately 4.8%. The Company believes that while actual development in recent years has ranged approximately from 3% to 7%, it is reasonable to expect that the range of the development could be as great as between 0% and 10%. However, actual development may be more or less than the expected range.

The following table presents the effects on loss development of different claim counts within the broader possible range at December 31, 2022:

California Automobile Bodily Injury Claim Count Reserve Sensitivity Analysis

Approximate average cost per claim Not meaningful $ 26,590 $ 26,590 $ 26,590

(3) Unexpected Losses From Older Accident Periods

Unexpected losses are generally not provided for in the current loss reserve because they are not known or expected and tend to be unquantifiable. Once known, the Company establishes a provision for the losses, but it is not possible to provide any meaningful sensitivity analysis as to the potential size of any unexpected losses. These losses can be caused by many factors, including unexpected legal interpretations of coverage, ineffective claims handling, regulations extending claims reporting periods, assumption of unexpected or unknown risks, adverse court decisions as well as many unknown factors. During 2022, the Company did not incur any material unexpected losses related to claims from accident periods prior to 2019.

Unexpected losses are fairly infrequent but can have a large impact on the Company’s losses. To mitigate this risk, the Company has established claims handling and review procedures. However, it is still possible that these procedures will not prove entirely effective, and the Company may have material unexpected losses in future periods. It is also possible that the Company has not identified and established a sufficient loss reserve for all material unexpected losses occurring in the older accident years, even though a comprehensive claims file review was undertaken. The Company may experience additional development on these loss reserves.

Discussion of Losses and Loss Reserves and Prior Period Loss Development

At December 31, 2022 and 2021, the Company recorded its point estimate of approximately $2.58 billion and $2.23

billion ($2.56 billion and $2.19 billion, net of reinsurance), respectively, in loss and loss adjustment expense reserves, which included approximately $1.28 billion and $1.03 billion ($1.28 billion and $1.02 billion, net of reinsurance), respectively, of incurred-but-not-reported liabilities ("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 December 31, 2022 and 2021, and estimated future payments for reopened claims. Management believes that the liability for losses and loss adjustment expenses 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. For 2022, the Company reported unfavorable development of approximately $47 million on the 2021 and prior accident years’ loss and loss adjustment expense reserves. The unfavorable development in 2022 was primarily attributable to higher than estimated losses and loss adjustment expenses in the automobile line of insurance business. In 2022, inflationary trends accelerated to their highest level in decades, which had a significant impact on the cost of automobile parts and labor as well as medical expenses for bodily injuries, and supply chain and labor shortage issues lengthened the time to repair vehicles. Bodily injury costs were also under pressure from social inflation. These factors were major contributors to the adverse reserve development in the automobile line of insurance business.

The Company recorded catastrophe losses net of reinsurance of approximately $102 million in 2022. Catastrophe losses due to the events that occurred during 2022 totaled approximately $101 million, with no reinsurance benefits used for these losses. The majority of the 2022 catastrophe losses resulted from the deep freeze of Winter Storm Elliott and other extreme weather events in Texas, Oklahoma and Georgia, winter storms in California, and the impact of Hurricane Ian in Florida. In addition, the Company experienced unfavorable development of approximately $1 million on prior years' catastrophe losses in 2022.

RESULTS OF OPERATIONS

Year Ended December 31, 2022 Compared to Year Ended December 31, 2021

Revenues

Net premiums earned and net premiums written in 2022 increased 5.6% and 3.2%, respectively, from 2021. The increase in net premiums earned and written was primarily due to increases in the number of policies written outside of California, higher average premiums in the California homeowners line of insurance business, and rate increases in certain lines of insurance business in some states outside of California, partially offset by a decrease in the number of private passenger automobile policies written in California. During 2022, the Company discontinued offering twelve-month private passenger automobile policies on new and renewal businesses in most states where it operates, including California, which further offset the increase in net premiums written for the year ended December 31, 2022 compared to the same period in 2021. At December 31, 2022, the Company's twelve-month private passenger automobile policies represented approximately 21% of its total private passenger automobile policies in force.

Net premiums earned included ceded premiums earned of $81.0 million and $65.0 million in 2022 and 2021, respectively. Net premiums written included ceded premiums written of $81.3 million and $65.5 million in 2022 and 2021, respectively. The increase in ceded premiums earned and written resulted mostly from higher reinsurance coverage and rates and growth in the covered book of business.

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 less any applicable reinsurance. Net premiums written is a statutory measure designed to determine production levels.

The following is a reconciliation of total net premiums earned to net premiums written:

Expenses

Loss and expense ratios are used to interpret the underwriting experience of property and casualty insurance companies. The following table presents the Company's consolidated loss, expense, and combined ratios determined in accordance with GAAP:

Year Ended December 31,

Loss ratio is calculated by dividing losses and loss adjustment expenses by net premiums earned. The Company’s loss ratio was affected by unfavorable development of approximately $47 million and favorable development of approximately $26 million on prior accident years’ loss and loss adjustment expense reserves for the years ended December 31, 2022 and 2021, respectively. The unfavorable development in 2022 was primarily attributable to higher than estimated losses and loss adjustment expenses in the automobile line of insurance business. Inflationary trends accelerated to their highest level in decades in 2022, which had a significant impact on the cost of automobile parts and labor as well as medical expenses for bodily injuries, and supply chain and labor shortage issues lengthened the time to repair vehicles. Bodily injury costs were also under pressure from social inflation. These factors were major contributors to the adverse reserve development in the automobile line of insurance business. The favorable development in 2021 was primarily attributable to lower than estimated losses and loss adjustment expenses in the homeowners and private passenger automobile lines of insurance business.

The 2022 loss ratio was negatively impacted by a total of approximately $101 million of catastrophe losses, excluding unfavorable development of approximately $1 million on prior years' catastrophe losses, primarily due to the deep freeze of Winter Storm Elliott and other extreme weather events in Texas, Oklahoma and Georgia, winter storms in California, and the impact of Hurricane Ian in Florida. The 2021 loss ratio was negatively impacted by a total of approximately $109 million of catastrophe losses, excluding favorable development of approximately $5 million on prior years' catastrophe losses, primarily due to the deep freeze of Winter Storm Uri and other extreme weather events in Texas and Oklahoma, rainstorms, wildfires and winter storms in California, and the impact of Hurricane Ida in New Jersey and New York.

Excluding the effect of estimated prior periods’ loss development and catastrophe losses, the loss ratio was 81.3% and 71.5% for the years ended December 31, 2022 and 2021, respectively. The increase in the loss ratio was primarily due to increases in loss severity and frequency in the automobile line of insurance business. The inflationary pressures and the supply chain and labor shortage issues discussed above, coupled with a lag in obtaining timely rate increases to offset the effects of inflationary trends, led to a significant increase in automobile loss severity and increased losses and loss adjustment expenses for the insured events of the current accident year for 2022 compared to 2021. After bottoming out in the second quarter of 2020, automobile loss frequency has mostly been increasing and is near pre-pandemic levels. The Company has filed for rate increases in many states and is taking various non-rate actions to improve profitability.

Expense ratio is calculated by dividing the sum of policy acquisition costs and other operating expenses by net premiums earned. The decrease in the expense ratio is primarily due to lower expenses for advertising and profitability-related accruals combined with higher net premiums earned.

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; a combined ratio over 100% generally reflects unprofitable underwriting results.

Income tax (benefit) expense was $(158.0) million and $51.4 million for the years ended December 31, 2022 and 2021,

respectively. The $209.4 million decrease in income tax expense was mainly due to a significant decrease in pre-tax income of $970.0 million.

The Company’s effective income tax rate can be affected by several factors. These generally include large changes in fully-taxable income including net realized investment gains or losses, tax-exempt investment income, nondeductible expenses, and periodically, non-routine tax items such as adjustments to unrecognized tax benefits related to tax uncertainties. The effective income tax rate was 23.6% and 17.2% for 2022 and 2021, respectively. The effective income tax rate for 2022 was higher than the statutory tax rate of 21% because tax-exempt investment income of approximately $75 million was included in pre-tax loss of approximately $671 million, while the effective income tax rate for 2021 was lower than the statutory tax rate because tax-exempt investment income of approximately $74 million was included in pre-tax income of approximately $299 million.

LIQUIDITY AND CAPITAL RESOURCES

A. General

The Company is largely dependent upon dividends received from its insurance subsidiaries in the current and prior years to pay debt service costs and to make distributions to its shareholders. Under current insurance law, the Insurance Companies are entitled to pay ordinary dividends of approximately $151 million in 2023 to Mercury General. As of December 31, 2022, Mercury General had approximately $96 million in investments and cash that could be utilized to satisfy its direct holding company obligations.

The principal sources of funds for the Insurance Companies are premiums, sales and maturity of invested assets, and dividend and interest income from invested assets. The principal uses of funds for the Insurance Companies are the payment of claims and related expenses, operating expenses, dividends to Mercury General, and the purchase of investments.

B. Cash Flows

The Company has generated positive cash flow from operations 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 $412.7 million at December 31, 2022 as well as $175 million of undrawn credit in its unsecured credit facility, 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.

Net cash provided by operating activities for the year ended December 31, 2022 was $352.6 million, a decrease of $149.0 million compared to the year ended December 31, 2021. The decrease was primarily due to increases in payments for losses and loss adjustment expenses and policy acquisition costs, partially offset by an increase in premium collections, a decrease in payments for income taxes, and an increase in investment income received. The Company utilized the cash provided by operating activities during the year ended December 31, 2022 primarily for the net purchases of investment securities and payment of dividends to its shareholders. The average annual net cash provided by operating activities for the past 10 years was approximately $364 million, and cash generated from operations was sufficient to meet the liquidity requirements over this period.

See "D. Debt" below for cash flow related to outstanding debt.

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.

The following table presents the composition of the total investment portfolio of the Company at December 31, 2022:

(2)The fair value is measured using the net asset value practical expedient. See Note 4. Fair Value Measurements, of the Notes to Consolidated Financial Statements in "Item 8. Financial Statements and Supplementary Data" for additional information.

At December 31, 2022, 49.7% of the Company’s total investment portfolio at fair value and 59.7% of its total fixed maturity investments at fair value were invested in tax-exempt state and municipal bonds. Equity holdings consist of 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 December 31, 2022, 51.3% of short-term investments 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 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 investments 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.

The following table presents the maturities and durations of the Company's fixed maturity securities and short-term investments:

Short-Term Investments — —

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 valueat December 31, 2022, consistent with the average rating at December 31, 2021. The Company’s municipal bond holdings, of which 89.1% were tax exempt, represented 67.0% of its fixed maturity portfolio at December 31, 2022, at fair value, and were broadly diversified geographically.

To calculate the weighted-average credit quality ratings as disclosed throughout this Annual Report on Form 10-K, individual securities were weighted based on fair value and a credit quality numeric score that was assigned to each security’s average of ratings assigned by nationally recognized securities rating organizations.

Taxable holdings consist principally of investment grade issues. At December 31, 2022, fixed maturity holdings rated below investment grade and non-rated bonds totaled $6.6 million and $26.5 million, respectively, at fair value, and represented 0.2% and 0.6%, respectively, of total fixed maturity securities. The majority of non-rated issues are a result of municipalities pre-funding and collateralizing those issues with U.S. government securities with an implicit AAA equivalent credit risk. At December 31, 2021, fixed maturity holdings rated below investment grade and non-rated bonds totaled $7.1 million and $17.3 million, respectively, at fair value, and represented 0.2% and 0.4%, respectively, of total fixed maturity securities.

Credit ratings for the Company's fixed maturity portfolio were stable in 2022, with 95.0% of fixed maturity securities at fair value experiencing no change in their overall rating. 4.2% and 0.8% of fixed maturity securities at fair value experienced upgrades and downgrades, respectively, in 2022.

(1)Intermediate ratings are included at each level (e.g., AA includes AA+, AA and AA-).

U.S. Government Bonds

The Company had $158.6 million and $13.1 million, or 3.9% and 0.3% of its fixed maturity portfolio, at fair value, in U.S. government bonds at December 31, 2022 and 2021, respectively. At December 31, 2022, Moody's and Fitch ratings for

U.S. government issued debt were Aaa and AAA, respectively, although a significant increase in government deficits and debt could lead to a downgrade. 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 portfolio reflecting anticipated early calls was 1.4 years and 0.9 years at December 31, 2022 and 2021, respectively.

Municipal Securities

The Company had $2.74 billion and $2.84 billion, or 67.0% and 70.5% of its fixed maturity securities portfolio, at fair value, in municipal securities at December 31, 2022 and 2021, respectively, of which $395.2 million and $424.1 million, respectively, were insured by bond insurers. 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 bond ratings and the underlying credit ratings as of December 31, 2022 and 2021.

At December 31, 2022 and 2021, respectively, 65.5% and 56.8% of the insured municipal securities, at fair value, most of which were investment grade, were insured by bond insurers that provide credit enhancement in addition to the ratings reflected by the financial strength of the underlying issuers. At December 31, 2022 and 2021, 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 34.5% and 43.2% of insured municipal securities at December 31, 2022 and 2021, respectively, were insured by non-rated or below investment grade bond insurers that the Company believes did not provide credit enhancement. The modified duration of the municipal securities portfolio reflecting anticipated early calls was 3.6 years and 3.1 years at December 31, 2022 and 2021, 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 additional downgrades to below investment grade ratings by the rating agencies in the future, and such downgrades could impact the estimated fair value of those municipal bonds.

Mortgage-Backed Securities

At December 31, 2022 and 2021, respectively, the mortgage-backed securities portfolio of $166.3 million and $137.0 million, or 4.1% and 3.4% of the Company's fixed maturity securities portfolio, at fair value, was categorized as loans to "prime" residential and commercial real estate borrowers. The Company had holdings of $27.3 million and $25.2 million, at fair value, in commercial mortgage-backed securities at December 31, 2022 and 2021, respectively.

The weighted-average rating of the entire mortgage backed securities portfolio was AA at December 31, 2022 and 2021. The modified duration of the mortgage-backed securities portfolio reflecting anticipated early calls was 7.3 years and 7.9 years at December 31, 2022 and 2021, respectively.

Corporate Securities

At December 31, 2022 and 2021, respectively, the company had corporate securities of $569.6 million and $523.9 million, or 13.9% and 13.0% of its fixed maturity securities portfolio, at fair value. The weighted-average rating was A- and BBB+ at December 31, 2022 and 2021, respectively. The modified duration reflecting anticipated early calls was 3.1 years and 3.8 years at December 31, 2022 and 2021, respectively.

Collateralized Loan Obligations

At December 31, 2022 and 2021, the Company had collateralized loan obligations of $320.3 million and $314.2 million, respectively, which represented 7.8% of its fixed maturity securities portfolio, at fair value, at each of those dates. The weighted-average rating was A+ and AA- at December 31, 2022 and 2021, respectively. The modified duration reflecting anticipated early calls was 4.6 years and 6.3 years at December 31, 2022 and 2021, respectively.

Other Asset-Backed Securities

The Company had other asset-backed securities of $136.5 million and $200.2 million, which represented 3.3% and 5.0% of its fixed maturity securities portfolio, at fair value, at December 31, 2022 and 2021, respectively. The weighted-average

rating was A+ and AA- at December 31, 2022 and 2021, respectively. The modified duration reflecting anticipated early calls was 3.1 years and 2.6 years at December 31, 2022 and 2021, respectively.

Equity Securities

Equity holdings of $699.6 million and $970.9 million, at fair value, as of December 31, 2022 and 2021, respectively, consisted of preferred stocks, common stocks on which dividend income is partially tax-sheltered by the 50% corporate dividend received deduction, and private equity funds. The net (losses) gains due to changes in fair value of the Company’s equity portfolio were $(185.7) million and $107.7 million in 2022 and 2021, respectively. The primary cause for the decrease in fair value of the Company's equity securities in 2022 was the overall decline in equity markets, and the primary cause for the increase in fair value of the Company's equity securities in 2021 was the overall improvement in equity markets.

The Company’s common stock allocation is intended to enhance the return of and provide diversification for the total portfolio. At December 31, 2022, 14.2% of the total investment portfolio, at fair value, was held in equity securities, compared to 18.9% at December 31, 2021.

__________

(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. These notes mature on March 15, 2027. The Company used the proceeds from the notes to pay off the total outstanding balance of $320 million under the existing loan and credit facility agreements and terminated the agreements on March 8, 2017. The remainder of the proceeds from the notes was used 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 29, 2017, the Company entered into an unsecured credit agreement (the "2017 Credit Agreement") that provided for revolving loans of up to $50 million and was set to mature on March 29, 2022. On March 31, 2021, the Company entered into an amended and restated credit agreement (the "Amended and Restated Credit Agreement") that amended and restated the 2017 Credit Agreement. The Amended and Restated Credit Agreement increased the aggregate commitments by all the lenders to $75 million from $50 million under the 2017 Credit Agreement and extended the maturity date of the loan that was the subject of the 2017 Credit Agreement to March 31, 2026. On November 18, 2022, the Company entered into the First Amendment to Amended and Restated Credit Agreement (the "First Amendment"). 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. 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 20.8% at December 31, 2022, resulting in a 15.0 basis point commitment fee on the $175 million undrawn portion of the credit facility. As of February 14, 2023, a total of $25 million was drawn down under this facility on a three-month revolving basis at an annual interest rate of approximately 5.68%.

(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 debt issuance cost of approximately $0.9 million associated with the $200 million unsecured revolving credit facility maturing on November 16, 2026 is included in other assets in the Company's consolidated balance sheets and amortized to interest expense over the term of the credit facility.

The Company was in compliance with all of its financial covenants pertaining to minimum statutory surplus, debt to total capital ratio, and RBC ratio under the unsecured credit facility at December 31, 2022.

For a further discussion, see Note 8. Notes Payable, of the Notes to Consolidated Financial Statements in "Item 8. Financial Statements and Supplementary Data."

E. Uses of Capital

Dividends

Cash returned to shareholders through dividends in 2022, 2021 and 2020 totaled approximately $105.5 million, $140.2 million and $139.6 million, respectively. On February 10, 2023, the Board of Directors declared a $0.3175 quarterly dividend per share payable on March 29, 2023 to shareholders of record on March 15, 2023, with an expected payout of approximately $18 million. The Company currently expects quarterly dividends to continue in future periods, although the declaration and amount of any future cash dividends are at the discretion and subject to the approval of its Board of Directors. The decisions of the Company's Board of Directors regarding the amount and payment of dividends will depend on many factors, such as its financial condition, results of operations, capital requirements, business conditions, debt service obligations, industry practice, legal requirements, regulatory constraints, and other factors that its Board of Directors may deem relevant. The Company expects to fund its future dividend payments primarily with a combination of cash expected to be generated from future operations and cash and short-term investments on hand.

For a further discussion, see Note 13. Dividends, of the Notes to Consolidated Financial Statements in "Item 8. Financial Statements and Supplementary Data."

Capital Expenditures

The Company's capital expenditures were approximately $35.5 million, $41.4 million and $40.0 million for 2022, 2021 and 2020, respectively, and they were primarily related to improving the Company's information technology infrastructure and corporate facilities. The Company expects the capital spending for 2023 to be at a level similar to that for 2022 and intends to use the capital to continue to invest in its technology assets and improve corporate facilities. The Company expects to fund its

2023 capital expenditures primarily with a combination of cash expected to be generated from future operations and cash and short-term investments on hand.

Contractual Obligations

The Company’s material cash requirements include the following contractual obligations at December 31, 2022:

Contractual Obligations (4) Payments Due By Period

(Amounts in thousands)

__________

(1)The Company’s debt contains various terms, conditions and covenants which, if violated by the Company, would result in a default and could result in the acceleration of the Company’s payment obligations. Amounts differ from the balances presented on the consolidated balance sheets as of December 31, 2022 because the debt amounts above include interest, calculated at the stated 4.4% coupon rate, and exclude the discount and issuance costs of the debt.

(2)The Company is obligated under various non-cancellable lease agreements providing for office space, automobiles, office equipment, and electronic data processing equipment that expire at various dates through the year 2028. Lease obligations include $3.6 million in lease commitments that have not yet commenced as of December 31, 2022. See Note 7. Leases, of the Notes to Consolidated Financial Statements in "Item 8. Financial Statements and Supplementary Data" for additional information on lease obligations.

(3)Loss and loss adjustment expense reserves represents an estimate of amounts necessary to settle all outstanding claims, including IBNR as of December 31, 2022. The Company has estimated the timing of these payments based on its historical experience and expectation of future payment patterns. However, the timing of these payments may vary significantly from the amounts shown above. The ultimate cost of losses may vary materially from recorded amounts which are the Company’s best estimates. For more detailed information on the Company's historical loss experience and payment patterns, see "Overview—C. Critical Accounting Estimates" in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations," as well as Note 12. Loss and Loss Adjustment Expense Reserves, of the Notes to Consolidated Financial Statements in "Item 8. Financial Statements and Supplementary Data."

(4)The table excludes liabilities of $6.6 million related to uncertainty in tax settlements as the Company is unable to reasonably estimate the timing and amount of related future payments.

The Company expects to meet these contractual obligations primarily with a combination of cash expected to be generated from future operations and cash and short-term investments on hand, except for the payment of the principal of the debt, which is expected to be made with a future borrowing.

F. Regulatory Capital Requirements

The Insurance Companies must comply with minimum capital requirements under applicable state laws and regulations. The RBC formula is used by insurance regulators to monitor capital and surplus levels. It was designed to capture the widely varying elements of risks undertaken by writers of different lines of insurance business having differing risk characteristics, as well as writers of similar lines where differences in risk may be related to corporate structure, investment policies, reinsurance arrangements, and a number of other factors. The Company periodically monitors the RBC level of each of the Insurance Companies. As of December 31, 2022, 2021 and 2020, each of the Insurance Companies exceeded the minimum required RBC level, as determined by the NAIC and adopted by the state insurance regulators. None of the Insurance Companies’ RBC ratios were less than 330% of the authorized control level RBC as of December 31, 2022, none less than 400% as of December 31, 2021, and none less than 350% as of December 31, 2020. Generally, an RBC ratio of 200% or less would require some form of regulatory or company action.

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 $1.50 billion at December 31, 2022 and net premiums written in 2022 of $4.0 billion, the ratio of premiums written to surplus was 2.65 to 1.

Insurance companies are required to file an Own Risk and Solvency Assessment ("ORSA") with the insurance regulators in their domiciliary states. The ORSA is required to cover, among many items, a company’s risk management policies, the material risks to which the company is exposed, how the company measures, monitors, manages and mitigates material risks, and how much economic and regulatory capital is needed to continue to operate in a strong and healthy manner. The ORSA is intended to be used by state insurance regulators to evaluate the risk exposure and quality of the risk management processes within insurance companies to assist in conducting risk-focused financial examinations and for determining the overall financial condition of insurance companies. The Company filed its most recent ORSA Summary Report with the California DOI in November 2022. Compliance with the ORSA requirements did not have a material impact on the Company's consolidated financial statements.

The DOI in each state in which the Company operates is responsible for conducting periodic financial and market conduct 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 examinations:

State Exam Type Period Under Review Status

CA Premium Tax 2018-2021 Examination was completed in the third quarter of 2022.

During the course of and at the conclusion of these examinations, the examining DOI generally reports findings to the Company. The Company has not been notified of any material findings related to the coordinated multi-state financial examination that began in the second quarter of 2022, and no material findings were reported at the completion of the California premium tax examination in the third quarter of 2022.

Item 7A. 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 Company's 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 December 31, 2022, 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, 2021.

The following table presents municipal securities by state in descending order of holdings at fair value at December 31, 2022:

States Fair Value Average Rating

(Amounts in thousands)

At December 31, 2022, the 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 40.3% of the Company’s fixed maturity portfolio at December 31, 2022. 9.6% of the Company’s taxable fixed maturity securities were comprised of U.S. government bonds, which were rated AAA at December 31, 2022. 0.3% of the Company’s taxable fixed maturity securities, representing 0.1% of its total fixed maturity portfolio, were rated below investment grade at December 31, 2022. 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 the equity markets.

At December 31, 2022, the Company’s primary objective for common equity investments was current income. The fair

value of the equity investments consisted of $558.2 million in common stocks, $51.2 million in preferred stocks, and $90.1 million in private equity funds. Common stocks are typically valued for future economic prospects as perceived by the market.

Common stocks represented 11.4% of total investments at fair value at December 31, 2022. Beta is a measure of a security’s systematic (non-diversifiable) risk, which is measured as 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 December 31, 2022 and 2021:

December 31,

(Amounts in thousands, except Average Beta)

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 issues 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 portfolio at December 31, 2022, which represented 83.3% of total investments at December 31, 2022, at fair value, is subject to interest rate risk. As market interest rates decrease, the value of the portfolio increases and vice versa. A common measure of the interest sensitivity of fixed maturity assets 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 3.5 years at December 31, 2022.

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 December 31, 2022 would decrease by $148.0 million and $296.0 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.

Mercury General Corporation:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Mercury General Corporation and subsidiaries (the Company) as of December 31, 2022 and 2021, the related consolidated statements of operations, shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2022, and the related notes and financial statement schedules I, II, and IV (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 14, 2023 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. 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 audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

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

Loss and loss adjustment expense reserves

As discussed in Notes 1 and 12 to the consolidated financial statements, the Company estimates loss and loss adjustment expense reserves (loss reserves) to cover incurred losses and loss adjustment expenses. Specifically, loss reserves are established based on the Company’s assessment of claims pending and the development of prior years’ loss liabilities. As of December 31, 2022, the loss and loss adjustment expense reserves balance was $2.58 billion, which included catastrophe losses.

We identified the evaluation of loss reserves, excluding catastrophe losses, as a critical audit matter. Subjective auditor judgment was required to assess the Company’s selected methods and assumptions, such as paid and incurred loss development factors, used to estimate loss reserves. Specialized actuarial skills and knowledge were needed to evaluate the Company’s actuarial methodologies and the estimate of future claims payment and reporting patterns based on observed historical patterns.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company’s reserving process. This included controls related to the selection of methods and assumptions used in the estimate of loss reserves. We also

involved actuarial professionals with specialized skills and knowledge, who assisted in:

• assessing the Company’s methodology for estimating loss reserves by comparing it to generally accepted actuarial methods

• evaluating the Company’s estimates for certain lines of business by performing independent analyses of loss reserves using the Company’s underlying historical claims data

• evaluating the Company’s estimates for the remaining lines of business in comparison to internal experience and related industry trends

• developing a range of reserves based on actuarial methodologies and comparing to the Company’s total recorded loss reserves

• evaluating the year-over-year movements of the Company’s recorded loss reserves within the developed range of reserves.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors

Mercury General Corporation:

Opinion on Internal Control Over Financial Reporting

We have audited the Mercury General Corporation and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2022 and 2021, the related consolidated statements of operations, shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2022, and the related notes and financial statement schedules I, II, and IV (collectively, the consolidated financial statements), and our report dated February 14, 2023 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Report of Independent Registered Public Accounting Firm. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies

General

Mercury General Corporation ("Mercury General") and its subsidiaries (referred to herein collectively as the "Company") are primarily engaged in writing personal automobile insurance through 12 Insurance Companies in 11 states, principally California. The Company also writes homeowners, commercial automobile, commercial property, mechanical protection, fire, and umbrella insurance. The private passenger automobile line of insurance business was more than 64% of the Company’s direct premiums written in 2022, 2021, and 2020, and approximately 82%, 87%, and 88% of the private passenger automobile premiums were written in California in 2022, 2021, and 2020, respectively. Premiums written represents the premiums charged on policies issued during a fiscal period, which is a statutory measure designed to determine production levels.

(2)Mercury County Mutual Insurance Company is not owned but is controlled by the Company through a management contract.

(3)MICFL was dissolved in November 2022.

(4)Special purpose investment vehicle.

The consolidated 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. All intercompany transactions and balances have been eliminated.

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

The Company did not have other comprehensive income (loss) in 2022, 2021 and 2020.

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 revenue 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 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. Actual results could differ from those estimates.

Investments and Other Financial Instruments

Financial instruments recorded in the consolidated balance sheets include investments, note receivable, other receivables, accounts payable, options sold, and notes payable. The Company’s investments include securities issued by the U.S. government and its agencies, securities issued by states and municipal governments and agencies, certain corporate and other debt securities, equity securities, and exchange traded funds.

The Company applies the fair value option to all fixed maturity and equity securities and short-term investments at the time an eligible item is first recognized. 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 Financial Accounting Standards Board (the "FASB") for accounting for financial instruments. Gains and losses due to changes in fair value for items measured at fair value pursuant to application of the fair value option are included in net realized investment gains in the Company's consolidated statements of operations, while interest and dividend income on investment holdings are recognized on an accrual basis on each measurement date and are included in net investment income in the Company's consolidated statements of operations. The Company’s fixed maturity and equity securities are classified as “trading” and carried at fair value as required when applying the fair value option. The majority of equity holdings, including preferred stocks, are actively traded on national exchanges or trading markets, and are valued at the last transaction price on the balance sheet date.

The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Due to their short-term maturity, the carrying values of other receivables and accounts payable approximate their fair values. 98.2% of the fair value of its investments at December 31, 2022 is based on observable market prices, observable pricing parameters, or is derived from such prices or parameters. The availability of observable market prices and pricing parameters can vary by financial instrument. Observable market prices and pricing parameters of a financial instrument, or a related financial instrument, are used to derive a price without requiring significant judgment.

The Company may hold or acquire financial instruments that lack observable market prices or pricing parameters because they are less actively traded currently or in future periods. The fair value of such instruments is determined using techniques appropriate for each particular financial instrument. These techniques may involve some degree of judgment. The price transparency of the particular financial instrument will determine the degree of judgment involved in determining the fair value of the Company’s financial instruments. Price transparency is affected by a wide variety of factors, including the type of financial instrument, whether it is a new financial instrument and not yet established in the marketplace, and the characteristics particular to the transaction. Financial instruments for which actively quoted prices or pricing parameters are available or for which fair value is derived from actively quoted prices or pricing parameters will generally have a higher degree of price transparency. By contrast, financial instruments that are thinly traded or not quoted will generally have diminished price transparency. Even in normally active markets, the price transparency for actively quoted financial instruments may be reduced during periods of market dislocation. Alternatively, in thinly quoted markets, the participation of market makers willing to purchase and sell a financial instrument provides a source of transparency for products that otherwise are not actively quoted. For a further discussion, see Note 4. Fair Value Measurements.

Fixed maturity securities include debt securities, 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. Premiums and discounts on fixed maturities are amortized using first call date and are adjusted for anticipated prepayments. Premiums and discounts on mortgage-backed securities are adjusted for anticipated prepayment using the retrospective method, with the exception of some beneficial interests in securitized financial assets, which are accounted for using the prospective method.

Equity securities consist of preferred stocks, common stocks on which dividend income is partially tax-sheltered by the 50% corporate dividend received deduction, and private equity funds.

Short-term investments include money market accounts, options, and short-term bonds that are highly rated short duration securities and redeemable within one year.

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 December 31, 2022 and 2021. 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 December 31, 2022 and 2021, the Company had approximately $9 million and $32 million, respectively, in unfunded commitments to these VIEs.

Securities on Deposit

As required by statute, the Company’s insurance subsidiaries have securities deposited with the departments of insurance or similar governmental agencies in the states in which they are licensed to operate ("DOI") with fair values totaling approximately $14 million and $15 million at December 31, 2022 and 2021, respectively.

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. The Company does not defer advertising expenditures but expenses them as incurred.

The table below presents a summary of deferred policy acquisition cost amortization and net advertising expense:

Year Ended December 31,

(Amounts in millions)

Deferred policy acquisition cost amortization $ 654.6 $ 633.4 $ 627.8

Fixed Assets

Fixed assets are stated at historical cost less accumulated depreciation and amortization. A fixed asset classified as held for sale is measured at the lower of its carrying amount or fair value less cost to sell, and is presented separately from other fixed assets. The useful life for buildings is 40 years. Furniture, equipment, and purchased software are depreciated on a combination of straight-line and accelerated methods over 3 to 7 years. The Company has capitalized certain consulting costs, payroll, and payroll-related costs for employees related to computer software developed for internal use, which are amortized on a straight-line method over the estimated useful life of the software, generally not exceeding 7 years. In accordance with applicable accounting standards, capitalization ceases no later than the point at which a computer software project is

substantially complete and ready for its intended use. Leasehold improvements are amortized over the shorter of the useful life of the assets or the life of the associated lease.

The Company periodically assesses long-lived assets or asset groups including building and equipment, for recoverability when events or changes in circumstances indicate that their carrying amounts may not be recoverable. If the Company identifies an indicator of impairment, the Company assesses recoverability by comparing the carrying amount of the asset to the sum of the undiscounted cash flows expected to result from the use and the eventual disposal of the asset. An impairment loss is recognized when the carrying amount is not recoverable and is measured as the excess of carrying value over fair value. There were no impairment charges during 2022, 2021, and 2020.

Goodwill and Other Intangible Assets

Goodwill and other intangible assets arise as a result of business acquisitions and consist of the excess of the cost of the acquisitions over the tangible and intangible assets acquired and liabilities assumed and identifiable intangible assets acquired. Identifiable intangible assets consist of the value of customer relationships, trade names, software and technology, and favorable leases, which are all subject to amortization, and an insurance license which is not subject to amortization.

The Company evaluates goodwill and other intangible assets for impairment annually or whenever events or changes in circumstances indicate that it is more likely than not that the carrying amount of goodwill and other intangible assets may exceed their implied fair values. The Company qualitatively determines whether, more likely than not, the fair value exceeds the carrying amount of a reporting unit. There are numerous assumptions and estimates underlying the qualitative assessments including future earnings, long-term strategies, and the Company’s annual planning and forecasting process. If these planned initiatives do not accomplish the targeted objectives, the assumptions and estimates underlying the qualitative assessments could be adversely affected and have a material effect upon the Company’s financial condition and results of operations. In addition, the Company evaluates other intangible assets using methods similar to those used for goodwill described above. As of December 31, 2022 and 2021, goodwill and other intangible impairment assessments indicated that there was no impairment.

Premium Revenue Recognition

Premium revenue is recognized on a pro-rata basis over the terms of the policies in proportion to the amount of insurance protection provided. Premium revenue includes installment and other fees for services which are recognized in the periods in which the services are rendered. Unearned premiums represent the portion of the written premium related to the unexpired policy term. Unearned premiums are predominantly computed monthly on a pro-rata basis and are stated gross of reinsurance deductions, with the reinsurance deduction recorded in other assets. The Company evaluates its unearned premiums periodically for premium deficiencies by comparing the sum of expected claim costs, unamortized acquisition costs and maintenance costs, partially offset by investment income, to related unearned premiums. To the extent that any of the Company’s lines of insurance business become unprofitable, a premium deficiency reserve may be required. Net premiums written, a statutory measure designed to determine production levels, was $3.98 billion, $3.86 billion, and $3.61 billion in 2022, 2021, and 2020, respectively. The Company's net premiums written in 2020 was reduced by approximately $128 million due to premium refunds and credits to its eligible policyholders associated with the "Mercury Giveback" program for reduced driving and business activities following the outbreak of the COVID-19 pandemic.

Losses and Loss Adjustment Expenses

Unpaid losses and loss adjustment expenses are determined in amounts estimated to cover incurred losses and loss adjustment expenses and established based upon the Company’s assessment of claims pending and the development of prior years’ loss liabilities. These amounts include liabilities based upon individual case estimates for reported losses and loss adjustment expenses and estimates of such amounts that are incurred but not reported. Changes in the estimated liability are charged or credited to operations as the losses and loss adjustment expenses are re-estimated. The liability is stated net of anticipated salvage and subrogation recoveries, and gross of reinsurance recoverables on unpaid losses.

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, such as those involving the Company’s bodily injury ("BI") coverages. Management believes that the liability for losses and loss adjustment expenses is adequate to cover the ultimate net cost of losses and loss adjustment expenses

incurred to date. However, since the provisions for loss reserves are necessarily based upon estimates, the ultimate liability may be more or less than such provisions.

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 ruling 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 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.

Derivative Financial Instruments

The Company accounts for all derivative instruments, other than those that meet the normal purchases and sales exception, as either an asset or liability, measured at fair value, which is based on information obtained from independent parties. In addition, changes in fair value are recognized in earnings unless specific hedge accounting criteria are met. See Note 9.Derivative Financial Instruments.

Earnings (Loss) Per Share

Basic earnings (loss) per share excludes dilution and reflects net income (loss) divided by the weighted average shares of common stock outstanding during the periods presented. Diluted earnings (loss) per share is based on the weighted average shares of common stock and potential dilutive securities outstanding during the periods presented. At December 31, 2022, potentially dilutive securities consisted of outstanding stock options. See Note 17. Earnings (Loss) Per Share, for the required disclosures relating to the calculation of basic and diluted earnings (loss) per share.

Income 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 earnings in the period that includes the enactment date.

The Company’s deferred income taxes usually include a combination of ordinary and capital deferred tax benefits and expenses. At December 31, 2022, the Company’s deferred income taxes were in a net asset position mainly due to deferred tax assets generated by unearned premiums, loss reserve discounting, and net unrealized losses on securities carried at fair value. These deferred tax assets were substantially offset by deferred tax liabilities resulting from deferred policy acquisition costs. 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, and to the extent management does not believe these assets are more likely than not to be realized, a valuation allowance is established. 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.

Management’s recoverability assessment of the Company’s deferred tax assets which are ordinary in character takes into consideration the Company’s strong history of generating ordinary taxable income and a reasonable expectation that it will continue to generate ordinary taxable income in the future. Further, the Company has the capacity to recoup its ordinary deferred tax assets through tax loss carryback claims for taxes paid in prior year. The Company also has various deferred tax liabilities that represent sources of future ordinary taxable income. Management’s recoverability assessment with regard to its capital deferred tax assets is based on estimates of anticipated capital gains, tax-planning strategies available to generate future taxable capital gains, and the Company's capacity to absorb capital losses carried back to prior years, each of which would contribute to the realization of deferred tax benefits. The Company has significant unrealized gains in its investment portfolio that could be realized through asset dispositions, at management’s discretion. In addition, the Company expects to hold certain debt securities, which are currently in loss positions, to recovery or maturity. Management believes unrealized losses related to these debt securities, which represent a portion of the unrealized loss positions at December 31, 2022, are fully realizable at maturity. Management believes its long-term time horizon for holding these securities allows it to avoid any forced sales prior to maturity. Further, the Company has the capability to generate additional realized capital gains by entering into sale-leaseback transactions using one or more of its appreciated real estate holdings. The realized gains on the real estate holdings could be used to realize both ordinary and capital deferred tax assets. The Company also has the capacity to recoup capital deferred tax assets through tax capital loss carryback claims for taxes paid within permitted carryback periods.

The Company has the capability to implement tax planning strategies as it has a steady history of generating positive cash flows from operations and believes that its liquidity needs can be met in future periods without the forced sale of its investments. This capability assists management in controlling the timing and amount of realized losses generated during future periods. By prudent utilization of some or all of these strategies, management has the intent and believes that it has the ability to generate capital gains and minimize tax losses in a manner sufficient to avoid losing the benefits of its deferred tax assets. Management will continue to assess the need for a valuation allowance on a quarterly basis. Although realization is not assured, management believes it is more likely than not that the Company’s deferred tax assets will be realized.

Contingent Liabilities

The Company has known, and may have unknown, potential liabilities which include claims, assessments, lawsuits, or regulatory fines and penalties relating to the Company’s business. The Company continually evaluates these potential liabilities and accrues for them and/or discloses them in the notes to the consolidated financial statements where required. In addition, the Company accrues for anticipated legal defense costs associated with lawsuits, claims or regulatory actions. 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. See Note 18. Commitments and Contingencies, for the required disclosures relating to contingent liabilities.

Reinsurance

Liabilities for unearned premiums and unpaid losses are stated in the accompanying consolidated financial statements before deductions for ceded reinsurance. Unpaid losses and unearned premiums that are ceded to reinsurers are carried in reinsurance recoverables and other assets, respectively, in the Company's consolidated balance sheets. Reinsurance recoverables on unpaid losses are estimated based upon assumptions consistent with those used in establishing the liabilities related to the underlying contracts. Most of the Company's reinsurance premiums are recognized ratably over the contract period to the extent coverage remains available. Net premiums earned and losses and loss adjustment expenses are stated net of deductions for ceded reinsurance.

The Company is the assuming reinsurer under a Catastrophe Portfolio Participation Reinsurance Contract ("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%.

The Company is party to a Catastrophe Reinsurance Treaty ("Treaty") covering a wide range of perils that is effective through June 30, 2023. The Treaty provides $936 million of coverage on a per occurrence basis after covered catastrophe losses exceed the $60 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 certain upper layers 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:

Year Ended December 31,

(Amounts in thousands)

Premiums Written

Premiums Earned

The Company recognized ceded premiums earned of approximately $81 million, $65 million, and $56 million in 2022, 2021, and 2020, respectively, which are included in net premiums earned in its consolidated statements of operations, and ceded losses and loss adjustment expenses of approximately $(13) million, $(10) million, and $(28) million in 2022, 2021, and 2020, respectively, which are included in losses and loss adjustment expenses in its consolidated statements of operations. The negative ceded losses and loss adjustment expenses in each of 2022 and 2021 was primarily the result of favorable development on prior years' catastrophe losses that had previously been ceded to the Company's reinsurers. The negative ceded losses and loss adjustment expenses in 2020 was mainly due to the reimbursements from Pacific Gas and Electric Corporation ("PG&E") Subrogation Trust Fund to the Company for claims paid to its policyholders related to certain wildfires. These loss recoveries from PG&E were ceded to the Company's reinsurers as the original losses had previously been ceded to its reinsurers under the Treaty.

The Insurance Companies, as primary insurers, are required to pay losses to the extent reinsurers are unable to discharge their obligations under the reinsurance agreements.

Share-Based Compensation

Share-based compensation expenses for all stock options granted or modified are based on their estimated grant-date fair values. The Company recognizes these compensation costs on a straight-line basis over the requisite service period of the award, which is the option vesting term of four years. The Company estimates forfeitures expected to occur in determining the amount of compensation cost to be recognized in each period. The fair value of stock option awards is estimated using the Black-Scholes option pricing model with the grant-date assumptions and weighted-average fair values. See Note 16. Share-Based Compensation for additional disclosures.

Revenue from Contracts with Customers

The Company's revenue from contracts with customers that are in scope of Topic 606 represents the commission income that the Company's 100% owned insurance agencies, Auto Insurance Specialists LLC ("AIS") and PoliSeek AIS Insurance Solutions, Inc. ("Poliseek"), earned from third-party insurers. The Company's commission income from third-party insurers was

approximately $18.2 million, $20.2 million and $18.0 million, with related expenses of approximately $11.0 million, $12.8 million and $11.8 million, for the years ended December 31, 2022, 2021 and 2020, respectively. Due to the immateriality of the Company's commission income and its related expenses to the overall consolidated financial statements, 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 in accordance with Topic 280, Segment Reporting (see Note 19. Segment Information).

AIS and PoliSeek are primarily engaged in the marketing and sales of insurance policies in private passenger automobile, commercial automobile and homeowners lines of business. Their revenues primarily consist of commission income received from property and casualty insurers. The primary performance obligation of AIS and Poliseek in return for the commission income from the insurers is to complete the sale of the policy and deliver the control of the policy to the insurer prior to the policy effective date. The total revenue from the sale of a policy is recognized when the sale is complete and the policy is effective as all the material aspects of the performance obligation are satisfied and the insurer is deemed to obtain control of the insurance policy at that time. The commission income is constrained such that the revenue is recognized only to the extent that the commission income received is not likely to be returned to the insurers due to policy cancellations. Any commission income not received when the sale is complete is recognized as commission income receivable, which is included in other receivables in the Company's consolidated balance sheets. Commission income receivable at December 31, 2022 and 2021 was approximately $1.3 million and $1.4 million, respectively.

A refund liability is recorded for the expected amount of the commission income that has to be returned to the insurers based on estimated policy cancellations. The refund liability is computed for the entire portfolio of contracts as a practical expedient, using the expected value method based on all relevant information, including historical data. The refund liability at December 31, 2022 and 2021 was approximately $0.8 million and $0.9 million, respectively, which was included in other liabilities in the Company's consolidated balance sheets.

As of December 31, 2022 and 2021, the Company had no contract assets and contract liabilities, and no remaining performance obligations associated with unrecognized revenues.

Capitalized Implementation Costs for Cloud Computing Arrangements

On January 1, 2020, the Company adopted Accounting Standards Update ("ASU") 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40), Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract," on a prospective basis, which provides guidance that requires capitalizing and amortizing certain of the implementation costs. The majority of the Company's cloud computing arrangements relate to service contracts with third parties that host the Company's data and computing infrastructure that are used in providing services to and supporting transactions with its existing or potential policyholders and insurance agents.

The balance of capitalized implementation costs for cloud computing arrangements, net of accumulated amortization, was $1.1 million and $2.8 million at December 31, 2022 and 2021, respectively, which is included in other assets in the Company's consolidated balance sheets. The accumulated amortization was $4.7 million and $6.0 million at December 31, 2022 and 2021, respectively. The total amortization expense related to such capitalized implementation costs was $2.8 million, $3.9 million, $1.8 million for the years ended December 31, 2022, 2021, and 2020, respectively, which is included in other operating expenses in the Company's consolidated statements of operations.

Allowance for Credit Losses

On January 1, 2020, the Company adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) along with certain additional ASUs on Topic 326 using a modified retrospective transition method, and recognized the cumulative-effect adjustment of approximately $2 million to the beginning retained earnings of 2020. The cumulative-effect adjustment primarily resulted from re-estimating credit losses on the outstanding balances of the Company's premiums receivable and reinsurance recoverables at the adoption date. Topic 326 replaced the "incurred loss" methodology for recognizing credit losses with a methodology that reflects expected credit losses for financial assets that are not accounted for at fair value through net income. The Company's investment portfolio, not including accrued investment income, was not affected by Topic 326 as it applies the fair value option to all of its investments.

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. The Company monitors the credit risk associated with premiums receivable, taking into consideration the fact that credit risk is reduced by the Company's right to offset unearned premiums against premiums receivable. The Company has established an allowance for uncollectible premiums receivable related to credit risk, and the estimated allowance is reviewed quarterly and adjusted as appropriate based on evaluations of balances due from insureds, management’s experience, historical data, current economic conditions, and reasonable and supportable forecasts of future economic conditions that affect the collectibility of the reported amounts. 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.

Evaluating the current trends or economic conditions that impact the Company's ability to collect premiums receivable and projecting those into the remaining life of premiums receivable in order to develop a reasonable and supportable forecast of the ultimate collectibility involve significant judgment and assumptions about future economic conditions. The Company monitors the overall credit risk of premiums receivable by regularly reviewing macroeconomic indicators such as trends in unemployment, inflation and interest rates, regulatory developments such as restrictions on cancellation of policies for nonpayment of premiums, and insurance policy specific indicators such as trends in policy cancellations. The improving economy and declining unemployment rate contributed to the reduction in allowance for credit losses in 2021. However, the rising inflation and interest rates had negative impacts on the allowance for credit losses in 2022, mostly offsetting the positive impacts of some improvements in the economy.

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

Year Ended December 31,

Cumulative effect of adopting ASU 2016-13 — — 1,855

Provision during the period for expected credit losses 4,213 (893) 10,294

Recoveries during the period of amounts previously written off 614 586 812

Accrued Interest Receivables

The Company made certain accounting policy elections for its accrued interest receivables on the adoption date of Topic 326 as allowed: 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.

As a general policy, the Company writes off the accrued interest receivable balance when it receives a default notice or when the scheduled interest payment is not received, unless management determines that the default is temporary considering all of the relevant information. The Company believes that for the majority of its investment securities, writing off the uncollectible interest receivable balance within a year from the due date is considered timely. In all cases, the Company writes off the accrued interest receivable immediately if management determines that it is not reasonably expected that the payment will be received. The Company did not have any cumulative-effect adjustment as a result of adopting Topic 326 for its accrued interest receivables. The Company's accrued interest receivable balances are included in accrued investment income receivables in its consolidated balance sheets. There were no accrued interest receivable amounts considered uncollectible or written off for the years ended December 31, 2022, 2021 and 2020.

Recently Issued Accounting Standards

In March 2020, the Financial Accounting Standards Board ("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.

2.Financial Instruments

Financial instruments recorded in the consolidated balance sheets include investments, other receivables, options sold, accounts payable, and notes payable. Due to their short-term maturity, 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:

December 31,

(Amounts in thousands)

Assets

Liabilities

Investments

The Company applies the fair value option to all fixed maturity and equity securities and short-term investments at the time an eligible item is first recognized. The cost of investments sold is determined on a first-in and first-out method, and realized and unrealized gains and losses are included in net realized investment gains in the Company's consolidated statements of operations. See Note 3. Investments for additional information.

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 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 December 31, 2022 and 2021 and its $25 million drawdown under the unsecured credit facility at December 31, 2022 were obtained from third party pricing services.

Contractual Maturity

At December 31, 2022, fixed maturity holdings rated below investment grade and non-rated comprised 0.6% of total investments at fair value. Additionally, the Company owns securities that are credit enhanced by financial guarantors that are subject to uncertainty related to market perception of the guarantors’ ability to perform. Determining the estimated fair value of municipal bonds could become more difficult should markets for these securities become illiquid.

The following table presents the estimated fair values of the Company's fixed maturity securities at December 31, 2022 by contractual maturity. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

4. 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 set 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 value and the level of market price observability, as follows:

a. Quoted prices for similar assets or liabilities in active markets;

c. Either directly or indirectly observable inputs as of the reporting date.

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 98.2% of its investment portfolio from an independent pricing service at December 31, 2022.

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/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.
