LETTER TO 
  SHAREHOLDERS
DEAR SHAREHOLDERS, 
I am pleased to share that RLI delivered outstanding financial 
results in 2024. Through the dedication of our associate-
owners, we achieved strong top-line growth and our 29th 
consecutive year of underwriting profitability. These results 
were attained amid an active year of catastrophes and highly 
competitive market conditions. 
In 2024, we remained dedicated to providing exceptional 
products and best-in-class service to our customers. We 
strengthened our relationships with existing distribution 
partners and actively explored opportunities in new markets. 
By strategically managing our business and maintaining 
a strong balance sheet, we reinforced our position as a 
financially secure and stable market leader.
While we are proud of our achievements, we recognize 
the true measure of success lies in our ability to create 
sustainable, long-term value for our stakeholders. With this 
strategic priority guiding us, we invested in many areas of
our business to support RLI’s continued profitable growth
and success. 
ABOUT OUR BUSINESS
RLI is a U.S.-based, specialty insurance company that 
offers a diverse portfolio of tailored property, casualty and 
surety products. Our coverages are designed to protect our 
customers from life’s uncertainties so they can explore, create, 
build and thrive. We distribute our products through a trusted 
network of specialized wholesale and retail brokers and 
independent agents. 
At the core of RLI’s business model is our commitment to 
prudent risk selection. In exchange for a fair premium, we 
assume risks that individuals and businesses are unwilling 
or unable to bear alone. Our diversified product portfolio and 
disciplined underwriting approach enable us to navigate all 
market cycles, ensuring we remain a dependable partner for 
our customers. 
RLI is financially strong and stable, as demonstrated by our 
A+ (Superior) rating from AM Best and A (Strong) rating from 
S&P. In 2024, we proudly celebrated our 34th consecutive 
year on Ward’s 50 P&C Top Performers list. RLI is the only 
insurance company that has received this honor every year 
since the list’s inception.
What truly distinguishes us in the industry is our people and 
culture. We hire talented individuals who share our values 
and enable them to become owners of the company through 
our Employee Stock Ownership Plan. Our ownership culture 
promotes shared accountability and aligns employee and 
shareholder interests. It empowers our team members to 
continuously improve our business and make the best long-
term decisions that benefit our customers and the company.
We are also committed to being a strong partner to our 
agents and brokers. By investing in personal connections 
that cultivate mutual trust, we nurture these relationships to 
provide a solid foundation for collaboration and ensure we 
remain responsive to evolving customer needs.
MARKET CONDITIONS
The economy remained fundamentally strong in 2024, marked 
by robust consumer spending and substantial business 
investment. However, the insurance industry continued to be 
dynamic and faced challenges such as legal system abuse, 
significant catastrophe activity, increased severity of auto-
related losses and disruptions in select markets.
Our expertise, strong producer relationships and consistent 
underwriting appetite enabled us to leverage our core 
strengths and navigate market challenges. As a result, we 
capitalized on opportunities to serve more customers and 
achieved profitable growth.
UNDERWRITING RESULTS 
In 2024, we posted underwriting income of $211 million 
and a combined ratio of 86.2, compared to $173 million of 
underwriting income and an 86.6 combined ratio in 2023. 
Gross premiums written increased 11 percent in 2024, and 
we surpassed $2 billion in premium for the first time, driven 
by growth across all three of our product segments. 
Our casualty segment reported a 15 percent increase in gross 
premiums written and a 97.9 combined ratio. Growth was 
fueled by rate increases across a large portion of our casualty 
segment, as well as new business growth within our personal 
umbrella and small commercial distribution channels. We 
also experienced an increase in new business opportunities 
across other product lines, including commercial excess and 
commercial transportation. 
The property segment reported a 7 percent increase in gross 
premiums written and a 68.5 combined ratio, despite the 
impact of hurricane activity. Our marine and commercial 
property products led segment growth, which was driven by 
rate increases and strong new business flow. 
4

Our surety segment achieved a 9 percent increase in 
gross premiums written and an 82.2 combined ratio.
This growth was driven by all surety lines, which benefited 
from favorable economic conditions and an expansion of 
accounts and producer partnerships. 
Overall, our underwriting performance was excellent. 
We believe the investments we made to enhance our 
products, underwriting talent, distribution relationships 
and technology have positioned us to remain competitive 
in the markets we serve.
INVESTMENT RESULTS
In addition to underwriting profit, investment income 
contributed to operating earnings. Our well-balanced, 
diversified investment portfolio provides consistent 
support for our operations and enhances RLI’s financial 
stability, ensuring we can meet our obligations to 
policyholders. 
Investment income increased 18 percent during the
year. This was driven primarily by higher reinvestment
rates and growth in our invested asset base, which 
was supported by strong operating cash flows. Overall, 
our investment portfolio achieved a total return of 6.4 
percent. We continue to maintain a thoughtful, long-term 
approach to managing our invested assets. 
DELIVERING SHAREHOLDER VALUE
In 2024, we increased regular dividends for the 49th 
consecutive year and paid a $2.00 per share special 
dividend. RLI has returned nearly $1.5 billion to 
shareholders through regular and special dividends
over the past decade.
We believe book value growth is the best measure of 
value creation. Book value per share, including dividends, 
increased 24 percent year over year. Over the past 10 
years, RLI’s book value, inclusive of dividends, has 
increased 238 percent, which is an outcome of
our commitment to enhancing shareholder value.
STRATEGIC VISION FOR GROWTH
Our performance and results are a testament to our 
diversified specialty product portfolio, deep underwriting 
and claim expertise and our ability to embrace disruption 
where we understand the exposures and market 
environment.
To achieve sustainable long-term growth for our 
shareholders, we will maintain focus on three key
strategic priorities: investing in initiatives that make it 
easier to do business with RLI; continuously enhancing 
our products, service and relationships; and cultivating 
our culture of ownership and underwriting discipline. With 
the support of our associate-owners, we will continue 
to implement our strategic plan and demonstrate that 
Different Works.
On behalf of our Board of Directors, thank you for your 
investment and confidence in our company. 
Craig W. Kliethermes
President & Chief Executive Officer

The following is selected financial data of RLI Corp. and Subsidiaries for the 5 years ended December 31, 2024.
(Amounts in thousands, except per share data and combined ratios)

11
(1) Operating earnings and operating earnings per share (EPS) consist of our GAAP net earnings adjusted by net realized gains/
(losses), net unrealized gains/(losses) on equity securities and taxes related thereto. Additionally, equity in earnings of Maui Jim and 
the related taxes were excluded from operating earnings and operating EPS due to the sale of RLI’s investment in 2022. Operating 
earnings and operating EPS for prior periods have been restated to reflect the equity in earnings of Maui Jim adjustment. Net 
earnings and net earnings per share are the GAAP financial measures that are most directly comparable to operating earnings and 
operating EPS.
(2) Ratios and surplus information are presented on a statutory basis. As discussed in Item 7, Management’s Discussion and Analysis 
of Financial Condition and Results of Operations, statutory accounting principles differ from GAAP and are generally based on 
a solvency concept. Further discussion is included in note 8 to the consolidated financial statements within Item 8, Financial 
Statements and Supplementary Data. Reporting of statutory surplus is a required disclosure under GAAP.
(3) On January 15, 2025, our stock split on a 2-for-1 basis. All share and per share data reflect the stock split.
(4) See Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations for information regarding key 
performance measures.

RLI Corp. 
Annual Report on Form 10-K 
For the Fiscal Year Ended December 31, 2024 
 
On January 15, 2025, RLI Corp. effected a two-for-one split of its commons stock and a proportionate increase in the number of 
authorized shares. All share and per share information throughout this report has been retroactively adjusted to reflect the stock split. 
 
PART I 
Item 1. Business 
 
RLI Corp. was founded in 1965. References to “the Company,” “we,” “our,” “us” or like terms refer to the business of RLI 
Corp. and its subsidiaries. We underwrite select property, casualty and surety products through major subsidiaries collectively known 
as RLI Insurance Group. We conduct operations through three insurance companies. RLI Insurance Company (RLI Ins.), a subsidiary 
of RLI Corp. and our principal insurance subsidiary, writes multiple lines of insurance on an admitted basis in all 50 states, the District 
of Columbia, Puerto Rico, the Virgin Islands and Guam. Mt. Hawley Insurance Company (Mt. Hawley), a subsidiary of RLI Ins., 
writes excess and surplus lines insurance on a non-admitted basis in all 50 states, the District of Columbia, Puerto Rico, the Virgin 
Islands and Guam. Contractors Bonding and Insurance Company (CBIC), a subsidiary of RLI Ins., writes multiple lines of insurance 
on an admitted basis in all 50 states and the District of Columbia. Each of our insurance companies is domiciled in Illinois. We have 
no material foreign operations. 
 
As a specialty insurance company with a niche focus, we offer insurance coverages in the specialty admitted and excess and 
surplus markets. We distribute our property, casualty and surety products through locations across the country that market to 
wholesale and retail brokers, independent agents and carrier partners. We offer limited coverages on a direct basis to select insureds, 
as well as various reinsurance coverages. From time to time, we also write a limited amount of business under agreements with 
managing general agents under the direction of our product leadership. 
 
We make our annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to 
those reports filed with or furnished to the Securities and Exchange Commission (SEC) available free of charge on our website 
(http://www.rlicorp.com). Information contained on our website is not intended to be incorporated by reference in this annual report 
and you should not consider that information a part of this annual report. The SEC also maintains a website (http://www.sec.gov) that 
contains reports, proxy and information statements and other information regarding the Company. 
 
SPECIALTY INSURANCE MARKET OVERVIEW 
 
The specialty insurance market differs significantly from the standard market. In the standard market, products and coverage are 
largely uniform with relatively predictable exposures and companies tend to compete for customers on the basis of price. In contrast, 
the specialty market provides coverage for risks that do not fit the underwriting criteria of the standard carriers. Competition tends to 
focus less on price and more on availability, coverage, service and other value-based considerations. While specialty market exposures 
may have higher insurance risks than their standard admitted market counterparts, we manage these risks to achieve superior financial 
returns. To reach our financial and operational goals, we must have extensive knowledge of, and expertise in, our markets. Many of 
our risks are underwritten on an individual basis and tailored coverages are employed in order to respond to distinctive risk 
characteristics. We operate in the specialty admitted insurance market, the excess and surplus insurance market and the specialty 
reinsurance markets. 
 
SPECIALTY ADMITTED INSURANCE MARKET 
 
We write business in the specialty admitted market. Many of these risks are unique and harder to place than in the standard 
admitted market, but for marketing, regulatory or contractual reasons, they must remain with an admitted insurance company. The 
specialty admitted market is subject to greater state regulation than the excess and surplus market, particularly with regard to rate and 
form filing requirements, restrictions on the ability to exit lines of business, premium tax payments and membership in various state 
associations, such as state guaranty funds and assigned risk plans. For 2024, our specialty admitted operations produced gross 
premiums written of $1.1 billion, representing approximately 57 percent of our total gross premiums for the year. 
 
EXCESS AND SURPLUS INSURANCE MARKET 
 
The excess and surplus market focuses on hard-to-place risks. Participating in this market allows the Company to underwrite 
non-standard risks with more flexible policy forms and unregulated premium rates. This typically results in coverages that are more 
restrictive and, in many cases, more expensive than in the standard admitted market. The excess and surplus lines environment and 

4 
production model effectively filter submission flow and match market opportunities to our expertise and appetite. The excess and 
surplus market represented less than 10 percent of the entire domestic property and casualty industry as of December 31, 2024, 
according to AM Best and as measured by direct premiums written. Our excess and surplus operations wrote gross premiums of $848 
million, or 42 percent, of our total gross premiums written in 2024. 
 
SPECIALTY REINSURANCE MARKET 
 
The business we write in the specialty reinsurance market is generally written on a portfolio basis. We write contracts on an 
excess of loss and a proportional basis. Contract provisions are written and agreed upon between the company and its reinsurance 
clients. The business is typically more volatile as a result of unique underlying exposures and excess and aggregate attachments. For 
2024, our specialty reinsurance operations wrote gross premiums of $27 million, representing approximately 1 percent of our total 
gross premiums written for the year. 
 
BUSINESS SEGMENT OVERVIEW 
 
Our insurance operations consist of three segments: property, casualty and surety. For additional information, see note 11 to the 
consolidated financial statements within Item 8, Financial Statements and Supplementary Data. The table below summarizes the 
composition of net premiums earned by major product.

CASUALTY SEGMENT 
 
Commercial Excess and Personal Umbrella 
 
Our commercial excess coverage is written in excess of primary liability insurance provided by other carriers and, in some 
cases, in excess of primary liability written by the Company. The personal umbrella coverage is generally written in excess of 
homeowners’ and automobile liability coverage provided by other carriers.  
 
Commercial Transportation 
 
Our transportation insurance provides commercial automobile liability and physical damage insurance to local, intermediate and 
long-haul truckers, public transportation entities and other types of specialty commercial automobile risks. We also offer incidental 
related insurance coverages including general liability, excess liability and motor truck cargo. 
 

5 
General Liability 
 
Our general liability business consists primarily of third-party liability coverage for commercial insureds including 
manufacturers, contractors, apartments and mercantile. We also offer coverages for security guards and environmental liability 
coverages for underground storage tanks, contractors and asbestos and environmental remediation specialists.  
 
Professional Services 
 
We offer professional liability coverages focused on providing errors and omission coverage for small to medium-sized design, 
technical, computer and other miscellaneous professionals. Our product suite for these customers also includes a full array of multi-
peril package products including general liability, property, automobile, excess liability and workers’ compensation coverages. 
 
Small Commercial 
 
Our small commercial business offers property and casualty insurance coverages for small to mid-sized contractors. The 
coverages included in these packages are predominantly general liability, but also include some inland marine coverages, as well as 
commercial automobile, property and excess liability coverage. 
 
Executive Products 
 
We provide a suite of management liability coverages, such as directors and officers (D&O) liability insurance, fiduciary 
liability, employment practice liability and fidelity coverages, for a variety of risk classes, including both public and private 
businesses. Our publicly traded D&O appetite generally focuses on offering excess Side A D&O coverage (where corporations cannot 
indemnify the individual directors and officers) as well as excess full coverage D&O.  
 
Other Casualty 
 
We offer a variety of other smaller products in our casualty segment, including home business insurance, which provides limited 
liability and property coverage for a variety of small business owners who work from their own home. We have a quota share 
reinsurance agreement with Prime Insurance Company and Prime Property and Casualty Insurance Inc., the two insurance subsidiaries 
of Prime Holdings Insurance Services, Inc. (Prime). Through our reinsurance agreement with Prime, we assume general liability, 
excess, commercial auto, property and professional liability coverages on hard-to-place risks that are written in the excess and surplus 
and admitted insurance markets. Separately, we assume mortgage reinsurance, which provides credit risk transfer on pools of 
mortgages. We also offer general liability and package coverages through a binding authority group, a program in which select surplus 
lines producers are granted limited underwriting authority through our online system to bind business on behalf of the Company.  
 
PROPERTY SEGMENT 
 
Commercial Property 
 
Our commercial property coverage consists primarily of excess and surplus lines and specialty insurance such as fire, 
earthquake, wind and difference in conditions (DIC), which can include earthquake, flood and collapse coverages. We provide 
insurance for a wide range of commercial and industrial risks, such as office buildings, apartments, condominiums and certain 
industrial and mercantile structures.  
 
Marine 
 
Our marine coverages include cargo, hull, protection and indemnity, marine liability, as well as inland marine coverages 
including builders’ risks and contractors’ equipment. Although the predominant exposures are located within the United States, there 
is some incidental international exposure written within these coverages.  
 
Other Property 
 
We offer specialized homeowners’ and dwelling fire insurance in Hawaii, as well as property coverages packaged through our 
binding authority group.  
 

6 
SURETY SEGMENT 
 
Transactional 
 
Our transactional surety coverage includes small bonds for businesses and individuals. Examples of these bond types are license 
and permit, notary and court bonds. The underwriting and delivery of these bonds is highly automated.  
 
Commercial 
 
We offer a variety of commercial surety bonds for medium to large-sized businesses across a broad spectrum of industries, 
including the financial, healthcare, energy and renewable energy industries. 
 
Contract 
 
We offer bonds for small to medium-sized contractors throughout the United States, underwritten on an account basis. 
Typically, these are performance and payment bonds that guarantee commercial contractors’ contractual obligations for a specific 
construction project. We also offer bonds for small and emerging contractors that are reinsured through the Federal Small Business 
Administration.  
 
MARKETING AND DISTRIBUTION 
 
We distribute our coverages across the country, primarily through wholesale and retail brokers, independent agents and carrier 
partners. 
 
BROKERS 
 
Our commercial property, general liability, commercial surety, executive products, commercial excess, marine and commercial 
transportation coverages are sold through independent wholesale and retail brokers. 
 
INDEPENDENT AGENTS 
 
We distribute products such as homeowners’ and dwelling fire, home business, surety, commercial transportation, professional 
services, small commercial and personal umbrella through independent agents. Several of these products require detailed eligibility 
criteria, which are incorporated into strict underwriting guidelines, and each risk is prequalified through a system that is accessible to 
the independent agent. The independent agent cannot bind the risk unless they receive approval from either our underwriters or 
automated systems. 
 
CARRIER PARTNERS 
 
We partner with other insurance carriers for home business and personal umbrella coverage. The carriers place this business 
with us through their associated agencies when the underlying risk does not meet their underwriting appetite. 
 
UNDERWRITING AGENTS 
 
We contract with select underwriting agencies that have limited authority to bind or underwrite business on our behalf. The 
underwriting agreements include strict guidelines, and the agents are subject to regular audits. 
 
DIRECT 
 
We utilize digital platforms to efficiently produce, process and service select business, including home business, binding 
authority, small commercial, personal umbrella and surety. 
 
COMPETITION 
 
Our specialty property and casualty insurance subsidiaries are part of a very competitive industry that is cyclical and historically 
characterized by periods of high premium rates and shortages of underwriting capacity followed by periods of severe competition and 
excess underwriting capacity. Within the United States alone, approximately 2,600 companies actively market property and casualty 
coverages. 

7 
 
Our primary competitors in the casualty segment include AIG, Allianz, Arch, Aspen, AXA/IL, Beazley, Berkley, 
Berkshire/National Indemnity, Chubb, CNA, Great American, Great West, Hartford, Hudson, James River, Kinsale, Lancer, Liberty, 
Markel, Nationwide, Progressive, RSUI, Sompo, Tokio Marine/HCC, Travelers, USLI, Westchester and Zurich. 
 
Our primary competitors in the property segment include AmRisc, Arch, Arrowhead, CNA, Golden Bear, Lexington, Liberty 
Mutual, Markel, Palomar, RSUI, Special Risk Underwriters, Travelers, Velocity and Westchester.  
 
Our primary competitors in the surety segment are AIG, Arch, Beazley, Berkley, Chubb, CNA, Great American, Hartford, 
Intact, Liberty Mutual, Markel, Merchants, Philadelphia, Sompo, Swiss Re, Travelers and Zurich.  
 
Capacity from managing general agents also increases competition in the property and casualty markets. The combination of 
coverages, service, pricing and other methods of competition vary from line to line. Our principal methods of winning business are 
innovative coverages, quality and consistent service to the agents and policyholders, and fair pricing. We compete favorably, in part, 
because of the value we add in relationships, the level of service we provide, the quality of our associate-owners, our sound financial 
condition and reputation, as well as our geographic footprint. In all segments, we have experienced underwriting and claim specialists. 
We continue to maintain our underwriting standards by not seeking market share at the expense of underwriting profit. We have a 
history of withdrawing from markets when conditions become overly adverse and offering new coverages and programs where the 
opportunity exists to provide needed risk transfer with exceptional service on a profitable basis. 
 
FINANCIAL STRENGTH RATINGS 
 
Financial strength ratings are an important factor in establishing the relative competitive position of insurance companies. The 
ratings are independent opinions of an insurer’s financial strength and ability to meet ongoing insurance policy and contract 
obligations, based on a comprehensive quantitative and qualitative analysis of balance sheet strength, operating performance, business 
profile and enterprise risk management. These ratings are based on factors relevant to policyholders, agents, insurance brokers and 
intermediaries and are not specifically related to securities issued by the company. Publications of AM Best, Standard & Poor’s and 
Moody’s indicate that A and A+ ratings are assigned to those companies that, in their opinion, have a superior ability to meet ongoing 
insurance obligations, a strong capacity to meet financial commitments or a low credit risk, respectively.  
 
At December 31, 2024, the following ratings were assigned to our insurance companies and represent affirmations of previously 
assigned ratings:

REINSURANCE 
 
In the ordinary course of business, we rely on other insurance companies to share risks through reinsurance, paying or ceding to 
the reinsurer a portion of the premiums received on such policies. These arrangements allow the Company to pursue greater 
diversification of business and serve to limit the maximum net loss on catastrophes and large risks. We use reinsurance as an 
alternative to using our own capital to take risks and reduce volatility. Retention levels are evaluated each year to maintain a balance 
between the growth in surplus and the cost of reinsurance. Although reinsurance does not legally discharge an insurer from its primary 
liability for the full amount of the policies, it does make the assuming reinsurer liable to the insurer to the extent of the insurance 
ceded. The following table illustrates the degree to which we have utilized reinsurance during the past three years. For an expanded 
discussion of the impact of reinsurance on our operations, see note 4 to the consolidated financial statements within Item 8, Financial 
Statements and Supplementary Data.

Reinsurance is subject to certain risks, including market risk, which affects the cost and ability to secure reinsurance contracts. 
Reinsurance is also subject to credit risk, which is the risk that our reinsurers may not pay on losses in a timely fashion or at all. We 
strive to purchase reinsurance from financially strong reinsurers. We evaluate reinsurers’ ability to pay based on their financial results, 
level of surplus, financial strength ratings and other risk characteristics. A reinsurance committee, comprised of senior management, 
reviews and approves our security guidelines and reinsurer usage. More than 93 percent of our reinsurance balances recoverable are 
due from companies with financial strength ratings of A or better by AM Best and Standard & Poor’s rating services. 
 
We utilize both treaty and facultative reinsurance coverage for our risks. Facultative coverage is applied to individual risks at the 
company’s discretion to supplement the limits provided by our treaty coverage or cover risks excluded from treaty reinsurance. Much 
of our reinsurance is purchased on an excess of loss basis. Under an excess of loss arrangement, we retain losses on a risk up to a 
specified amount and the reinsurers assume any losses above that amount. We may choose to participate in the reinsurance layers 
purchased by retaining a percentage of the layer. It is common to find conditions in excess of loss covers such as occurrence limits, 
aggregate limits and reinstatement premium charges. Occurrence limits cap our recovery for multiple losses caused by the same event. 
Aggregate limits cap our recovery for all losses ceded during the contract term. Lastly, we may be required to pay additional premium

PROPERTY REINSURANCE — CATASTROPHE COVERAGE 
 
Our property catastrophe reinsurance reduces the financial impact of a catastrophe event involving multiple claims and 
policyholders, including earthquakes, hurricanes, floods, wildfires, convective storms and certain other aggregating events. 
Reinsurance limits purchased fluctuate due to changes in the amount of exposure we insure, reinsurance costs, insurance company 
surplus levels and our risk appetite. In addition, we monitor the expected rate of return for each of our catastrophe lines of business. At 
high rates of return, we grow the book of business and may purchase additional reinsurance to increase our capacity. As the rate of 
return decreases, we may reduce exposure and may purchase less reinsurance as this capacity becomes unnecessary. Our reinsurance 
coverages for 2023 through 2025 are shown in the table below. Amounts for 2023 reflect additional catastrophe reinsurance protection 
that was purchased mid-year to support growth in our catastrophe-exposed business.

Our property catastrophe program continues to be applied on an excess of loss basis. Although covered in one program, limits 
and attachment points differ for California earthquakes and all other perils. These catastrophe limits are in addition to the per-
occurrence coverage provided by facultative and other treaty coverages. We have participated in the catastrophe layers purchased by 
retaining a percentage of various layers in certain years. Our participation has varied over time based on price and the amount of risk 
transferred by each layer. For 2025, the program was 100 percent placed, with a portion of the first layer expiring on May 31, 2025. 
All layers of the treaty include one reinstatement, some being prepaid reinstatements, while others require the payment of additional 
reinstatement premium. With the renewal effective January 1, 2025, the number of layers with prepaid reinstatement premium 
increased, which reduces the net loss impact on catastrophe events. Additionally, we have coverages that may reduce first-dollar 
retentions for multiple events within an established period of time. 
 
The following table shows the likelihood that a loss from a single event would be less than the amount shown. For example, the 
1-in-100 return period for hurricane means that the largest modeled hurricane occurrence had losses less than the amount shown in 99 
out of 100 modeled years, while the largest modeled hurricane occurrence exceeded the amount shown in one out of 100 modeled 
years. Losses were modeled based on our exposure as of December 31, 2024, utilizing the reinsurance treaty structure in place as of 
January 1, 2025. The loss amounts are pre-tax and include the impact of additional reinsurance reinstatement premium, if any.

Actual results could vary significantly from these modeled losses as the actual nature or severity of a particular event cannot be 
accurately predicted. Reinsurance limits are purchased based on the anticipated losses from large events. The largest losses shown 
above are possible, but have a lower probability of actually occurring. However, there is a remote chance that a larger event could 
occur. If the actual event losses are larger than anticipated, we could retain additional losses above the limit of our catastrophe 
reinsurance. 
 
We regularly monitor and quantify our exposure to catastrophes. In the normal course of business, we manage our 
concentrations of exposures to catastrophic events, primarily by limiting concentrations of locations insured to acceptable levels and 
by purchasing reinsurance. Exposure and coverage detail is recorded for each risk location. We quantify and monitor the total policy 
limit insured in each geographical region. In addition, we use third-party catastrophe exposure models and an internally developed 
analysis to assess each risk to ensure we include an appropriate charge for assumed catastrophe risks. 
 

10 
Catastrophe exposure modeling is inherently uncertain due to the model’s reliance on an infrequent observation of actual events, 
increasing the importance of capturing accurate policy coverage data. The modeled results are used both in the underwriting analysis 
of individual risks and at a corporate level for the aggregate book of catastrophe-exposed business. From both perspectives, we 
consider the potential loss produced by individual events that represent moderate-to-high loss potential at varying probabilities and 
magnitudes. In calculating potential losses, we use assumptions including, but not limited to, loss amplification and loss adjustment 
expense. We establish risk tolerances at the portfolio level based on market conditions, the level of reinsurance available, changes to 
the assumptions in the catastrophe models, rating agency capital constraints, underwriting guidelines and coverages and internal 
preferences. Our risk tolerances for each type of catastrophe, and for all perils in aggregate, change over time as these internal and 
external conditions change. 
 
We are required to report to the rating agencies estimated loss to a single event that could include all potential earthquakes and 
hurricanes contemplated by the catastrophe modeling software. This reported loss includes the impact of insured losses based on the 
estimated frequency and severity of potential events, loss adjustment expense, reinstatements paid after the loss, reinsurance 
recoveries and taxes. Based on the catastrophe reinsurance treaty purchased on January 1, 2025, there is a 99.6 percent likelihood that 
the net loss will be less than 2.6 percent of policyholders’ statutory surplus as of December 31, 2024. The exposure levels continue to 
be within our tolerances for this risk. Comparatively, based on the catastrophe reinsurance treaty purchased on January 1, 2024, there 
was a 99.6 percent likelihood that the net loss would have been less than 8.0 percent of policyholders’ statutory surplus as of 
December 31, 2023. The comparable metric over the past five years, as measured at the beginning of each of those treaty years, has 
ranged from 2.6 percent of surplus to 10.8 percent of surplus.  
 
OPERATING RATIOS 
 
PREMIUMS TO SURPLUS RATIO 
 
The following table shows, for the periods indicated, our insurance subsidiaries’ statutory ratios of net premiums written to 
policyholders’ surplus. While there is no statutory requirement applicable to the Company that establishes a permissible net premiums 
written to surplus ratio, guidelines established by the National Association of Insurance Commissioners (NAIC) provide that this ratio 
should generally be no greater than 3 to 1. While the NAIC provides this general guideline, rating agencies often require a more 
conservative ratio to maintain strong or superior ratings.

COMBINED RATIO AND STATUTORY COMBINED RATIO 
 
Our underwriting experience is best indicated by our combined ratio, which is the sum of (a) the ratio of incurred loss and 
settlement expenses to net premiums earned (loss ratio) and (b) the ratio of policy acquisition costs and insurance operating expenses 
to net premiums earned (expense ratio). The difference between the combined ratio and 100 reflects the per dollar rate of underwriting 
income or loss, with ratios below 100 indicating underwriting profit and ratios above 100 indicating underwriting loss.

We also calculate the statutory combined ratio, which is not indicative of underwriting income due to accounting for policy 
acquisition costs differently for statutory accounting purposes, but is a standardized industry measure. The statutory combined ratio is 
the sum of (a) the ratio of statutory loss and loss adjustment expenses incurred to statutory net premiums earned (loss ratio), (b) the 
ratio of statutory other underwriting expenses incurred to statutory net premiums written (expense ratio) and (c) the ratio of 
policyholder dividends to statutory net premiums earned (policyholder dividend ratio).

INVESTMENTS 
 
Our investment portfolio serves as a resource for loss payments and secondarily as a source of income to support operations. 
Our investment strategy is based on preservation of capital as the first priority, with a secondary focus on growing book value through 
total return. Investments of the highest quality and marketability are critical for preserving our claims-paying ability. In addition, we 
have a diversified investment portfolio that distributes credit risk across many issuers and an investment policy that limits aggregate 
credit exposure. Despite periodic fluctuations in market value, our equity portfolio is part of a long-term asset allocation strategy and 
has contributed significantly to our growth in book value over time. Our portfolio does not contain derivatives. 
 
Investment portfolios are managed both internally and externally by experienced portfolio managers. We follow an investment 
policy that is reviewed quarterly and revised periodically, with oversight conducted by our senior officers and board of directors. 
 
Our investments include fixed income debt securities, common stock equity securities, exchange traded funds (ETFs) and a 
small number of limited partnership interests. The fixed income portfolio was 78 percent of the total portfolio, the same as the 
prior year, while the equity allocation was 18 percent of the overall portfolio, up 2 percent from the previous year. Other invested 
assets represented 1 percent of the total portfolio and include investments in low-income housing tax credit and historic tax credit 
partnerships, membership stock in the Federal Home Loan Bank of Chicago and investments in private funds. The remaining 
3 percent was made up of cash and short-term investments. As of December 31, 2024, 79 percent of the fixed income portfolio was 
rated A or better and 57 percent was rated AA or better. 
 
We classify all the securities in our fixed income portfolio as available-for-sale, which are carried at fair value. Beyond 
available operating cash flow, the portfolio provides an additional source of liquidity and can be used to address potential future 
changes in our asset/liability structure. Aggregate maturities for the fixed income portfolio as of December 31, 2024, were as follows:

REGULATION 
 
STATE REGULATION 
 
As an insurance holding company, we and our insurance company subsidiaries, are subject to regulation by the states and 
territories in which the insurance subsidiaries are domiciled or transact business. Registration in each insurer’s state of domicile 
requires periodic reporting to such state’s insurance regulatory authority of the financial, operational and management information 
regarding the insurers within the holding company system. All transactions within a holding company system affecting insurers must 
have fair and reasonable terms, and the insurers’ policyholders’ surplus, following any transaction, must be both reasonable in relation 

12 
to its outstanding liabilities and adequate for its needs. Notice to and, in some cases, consent from regulators is required prior to the 
completion of certain transactions affecting insurance company subsidiaries of the holding company system. Each state and territory 
individually regulates the insurance operations of both insurance companies and insurance agents/brokers. Most insurance regulations 
are designed to protect the interests of policyholders rather than shareholders and other investors. 
 
The primary focus of state regulation of insurance companies is financial solvency and market conduct practices. Regulations 
designed to ensure the financial solvency of insurers are enforced by various filing, reporting and examination requirements. 
Marketplace oversight is conducted by monitoring and periodically examining trade practices, approving policy forms, licensing 
agents and brokers and requiring the filing and, in some cases, approval of premiums and commission rates to ensure they are fair and 
adequate. 
 
Because our insurance company subsidiaries operate in all 50 states, the District of Columbia, Puerto Rico, the Virgin Islands 
and Guam, we must comply with the individual insurance laws, regulations, rules and case law of each state and territory, including 
those regulating the filing of insurance rates and forms. Each of our three insurance company subsidiaries are domiciled in Illinois, 
with the Illinois Department of Insurance (IDOI) as its principal insurance regulator. Changes to the state insurance regulatory 
requirements are frequent, including changes caused by state legislation, regulations by the state insurance departments and court 
rulings. 
 
As a holding company, the amount of dividends we are able to pay depends upon the funds available for distribution, including 
dividends or distributions from our subsidiaries. The Illinois insurance laws applicable to our insurance company subsidiaries impose 
certain restrictions on their ability to pay dividends. The Illinois insurance holding company laws require that ordinary dividends paid 
by an insurance company be reported to the IDOI prior to payment of the dividend, and provide that extraordinary dividends may not 
be paid without such regulator’s prior approval (or the absence of disapproval). The IDOI has broad authority to prevent the reduction 
of statutory surplus to inadequate levels, and there is no assurance that extraordinary dividend payments would be permitted. 
 
Illinois has adopted the Amended Holding Company Model Act, which imposes reporting obligations on parents and other 
affiliates of licensed insurers or reinsurers, with the purpose of protecting the licensed companies from enterprise risk. The Amended 
Holding Company Model Act requires the ultimate controlling person (in our case RLI Corp.) to file an annual enterprise risk report 
identifying the material risks within the insurance holding company system that could pose enterprise risk to the licensed companies. 
An enterprise risk is generally defined as an activity or event involving affiliates of an insurer that could have a material adverse effect 
on the insurer or the insurer’s holding company system. We report on these risks on an annual basis and are in compliance with this 
law. 
 
Illinois has adopted the Own Risk and Solvency Assessment (ORSA) model act. ORSA is applicable to Illinois domiciled 
insurance companies that meet certain size requirements, including ours. The ORSA program is a key component of an insurance 
company’s overall enterprise risk management (ERM) framework, and is the process by which organizations identify, measure, 
monitor and manage key risks affecting the entire enterprise. The Company files an ORSA summary report with the IDOI each year, 
which includes an internal identification, description and assessment of the risks associated with our business plan and the sufficiency 
of capital resources to support those risks. 
 
The NAIC uses a risk-based capital (RBC) model to monitor and regulate the solvency of licensed property and casualty 
insurance companies. Illinois has adopted a version of the NAIC’s model law. The RBC calculation is used to measure an insurer’s 
capital adequacy with respect to: the risk characteristics of the insurer’s premiums written and unpaid losses and loss adjustment 
expenses, rate of growth and quality of assets, among other measures. Depending on the results of the RBC calculation, insurers may 
be subject to varying degrees of regulatory action. RBC is calculated annually by insurers, as of December 31 of each year. As of 
December 31, 2024, each of our insurance company subsidiaries had RBC levels significantly in excess of the company action level 
RBC, defined as being 200 percent of the authorized control level RBC, which would prompt corrective action under Illinois law. RLI 
Ins., our principal insurance company subsidiary, had an authorized control level RBC of $296 million compared to actual statutory 
capital and surplus of $1.8 billion as of December 31, 2024, resulting in statutory capital that is more than six times the authorized 
control level. The calculation of RBC requires certain judgments to be made, and, accordingly, each of our insurance company 
subsidiaries’ current RBC may be greater or less than the RBC calculated as of any date of determination. 
 
Each of our insurance company subsidiaries is required to file detailed annual reports, including financial statements, in 
accordance with prescribed statutory accounting rules, with regulatory officials in the jurisdictions in which they conduct business. 
The quarterly and annual financial reports filed with those states utilize statutory accounting principles (SAP) that are different from 
generally accepted accounting principles in the United States of America (GAAP). As a basis of accounting, SAP was developed to 
monitor and regulate the solvency of insurance companies. In developing SAP, insurance regulators were primarily concerned with 
assuring an insurer’s ability to pay all its current and future obligations to policyholders.  

13 
 
As part of their routine regulatory oversight process, state insurance departments conduct periodic detailed examinations, 
generally once every three to five years, of the books, records, accounts and operations of insurance companies that are domiciled in 
their states. Examinations are generally carried out in cooperation with the insurance departments of other, non-domiciliary states 
under guidelines promulgated by the NAIC. The most recent examination report of our insurance company subsidiaries completed by 
the IDOI was issued on December 29, 2023, for the five-year period ending December 31, 2022. The examination report is available 
to the public. 
 
Each of our insurance company subsidiaries is subject to Illinois laws and regulations that impose restrictions on the amount and 
type of investments our insurance company subsidiaries may have. Such laws and regulations generally require diversification of the 
insurer’s investment portfolio and limit the amounts of investments in certain asset categories, such as below investment grade fixed 
income securities, real estate-related equity, other equity investments and derivatives. Failure to comply with these laws and 
regulations would generally cause investments that exceed regulatory limitations to be treated as non-admitted assets for measuring 
statutory surplus and, in some instances, could require the divestiture of such non-qualifying investments. 
 
Many jurisdictions have laws and regulations that limit an insurer’s ability to withdraw from a particular market. For example, 
states may limit an insurer’s ability to cancel or non-renew policies. Furthermore, certain states prohibit an insurer from withdrawing 
one or more lines of business from the state, except pursuant to a plan that is approved by the state insurance department. The state 
insurance department may disapprove a withdrawal plan that may lead to marketplace disruption. Laws and regulations that limit 
cancellation and non-renewal, and that subject program withdrawals to prior approval requirements, may restrict our ability to exit 
unprofitable marketplaces in a timely manner. 
 
Virtually all states require licensed insurers to participate in various forms of guaranty associations in order to bear a portion of 
the loss suffered by qualified policyholders of insurance companies that become insolvent. Many states also operate an insurance plan, 
often referred to as the “insurer of last resort” to provide property insurance to state residents who are unable to obtain that insurance 
in the private market. Depending upon state law, licensed insurers can be assessed a small percentage of the annual premiums written 
for the relevant lines of insurance in that state to fund its guaranty association or insurer of last resort plan. These assessments may 
increase or decrease in the future, depending upon the rate of insurance company insolvencies. In some states, these assessments may 
be wholly or partially recovered through policy fees paid by insureds. We cannot predict the amount and timing of future assessments. 
Therefore, the liabilities we have currently established for these potential assessments may not be adequate and an assessment may 
materially impact our financial condition. 
 
In addition, the insurance holding company laws require advance approval by state insurance commissioners of any change in 
control of an insurance company that is domiciled, or in some cases, having such substantial business that it is deemed to be 
commercially domiciled in that state. “Control” is generally presumed to exist through the ownership of 10 percent or more of the 
voting securities of a domestic insurance company or of any company that controls a domestic insurance company. In addition, 
insurance laws in many states contain provisions that require pre-notification to the insurance commissioners of a change in control of 
a non-domestic insurance company licensed in those states. Any future transactions that would constitute a change in control of our 
insurance company subsidiaries, including a change of control of RLI Ins., would generally require the party acquiring control to 
obtain the prior approval by the insurance departments of the insurance company subsidiaries’ state of domicile (Illinois) or 
commercial domicile, if applicable. It may also require pre-acquisition notification in applicable states that have adopted pre-
acquisition notification provisions. Obtaining these approvals could result in a material delay of, or deter, any such transaction. 
 
In light of the number and severity of U.S. company data breaches, a number of states have enacted new insurance laws that 
require certain regulated entities to implement and maintain comprehensive information security programs to safeguard the personal 
information of insureds. For example, the New York State Department of Financial Services (NYDFS) enacted a comprehensive 
cybersecurity regulation in 2017, and revised the regulation in 2023. This regulation requires banks, insurance companies and other 
financial services institutions regulated by the NYDFS to establish and maintain a cybersecurity program “designed to protect 
consumers and ensure the safety and soundness of New York State’s financial services industry.” Other states have enacted similar 
regulations. These regulations are revised from time-to-time, such as New York’s second amendment to its cybersecurity act, 
requiring us to periodically revise our cybersecurity governance, processes and controls to comply with the revised regulations. 
 
A number of states have issued regulatory guidance to insurance companies authorized to do business in those respective states 
on the use of artificial intelligence (AI). A number of states have adopted the NAIC Model Bulletin on the Use of Artificial 
Intelligence, while the New York Department of Financial Services issued its circular letter. Such state guidance on the use of AI sets 
forth expectations that companies have governance and risk management practices in place to ensure the use of AI complies with 
various state laws governing the business of insurance. 
 

14 
The NAIC adopted the Insurer Climate Risk Disclosure Data Survey to provide regulators with information about the 
assessment of risks posed by climate change to insurers and the actions insurers are taking in response to their understanding of 
climate change risks. A number of states require the Company to provide annual responses to the survey, all of which accept the filing

2023, can be accessed on the California Department of Insurance website.  
 
The rates, policy terms and conditions of reinsurance agreements generally are not subject to regulation by any regulatory 
authority. However, the ability of a ceding insurer to take credit for the reinsurance purchased from reinsurance companies is a 
significant component of reinsurance regulation. Typically, a ceding insurer will only enter into a reinsurance agreement if it can 
obtain credit against its reserves on its statutory basis financial statements for the reinsurance ceded to the reinsurer. With respect to 
U.S. domiciled ceding companies, credit is usually granted when the reinsurer is licensed, accredited, certified or identified as a 
reciprocal jurisdiction reinsurer in the state where the ceding company is domiciled. States also generally permit ceding insurers to 
take credit for reinsurance if the reinsurer is: (1) domiciled in a state with a credit for reinsurance law that is substantially similar to the 
credit for reinsurance law in the primary insurer’s state of domicile and (2) meets certain financial requirements. Credit for reinsurance 
purchased from a reinsurer that does not meet the foregoing conditions is generally allowed to the extent that such reinsurer secures its 
obligations with qualified collateral. 
 
Insurers are also subject to state laws regulating claim handling practices. The NAIC created a model unfair claims practices law 
which most states have fully or partially adopted. These laws and regulations set the standards by which insurers must investigate and 
resolve claims; however, a private cause of action for violation is not available to claimants. These laws typically prohibit: 
(1) misrepresentation of policy provisions, (2) failing to act promptly when claims are presented and (3) refusing to pay claims 
without an investigation. Market conduct examinations or insurance regulator investigations may be prompted through annual reviews 
or excessive numbers of complaints against an insurer. After an investigation or market conduct review by an insurance regulator, 
insurers found to be in violation of these laws and regulations face potential fines, cease and desist orders, remediation orders or loss 
of authority to write business in the particular state. 
 
FEDERAL LEGISLATION AND REGULATION 
 
The U.S. insurance industry is not currently subject to any significant federal regulation related to the business of insurance and 
instead is regulated principally at the state level. The Company is subject to a number of federal regulatory requirements related to 
securities, employment practices, qualified employee benefits plans and financial disclosures, among others.  
 
Other federal laws and regulations apply to many aspects of our company and its business operations. These federal regulations 
include laws such as the Gramm-Leach-Bliley Act, which establishes privacy and security requirements for insurance companies, and 
enables state departments of insurance to enforce these requirements; and the Fair Credit Reporting Act as amended by the Fair and 
Accurate Credit Transactions Act, which establishes rules regarding access to and use of information (including but not limited to 
credit information and motor vehicle reports) from consumer reporting agencies. 
 
LICENSES AND TRADEMARKS 
 
We hold a U.S. federal service mark registration of our corporate name “RLI” and several other company service marks and 
trademarks with the U.S. Patent and Trademark Office. Such registrations protect our intellectual property nationwide from 
deceptively similar use. The duration of these registrations is 10 years, unless renewed. We monitor our trademarks and service marks 
and protect them from unauthorized use as necessary. 
 
HUMAN CAPITAL 
 
RLI is a specialty underwriting company whose achievement emanates from our entrepreneurial, ownership culture. We strive 
to hire top underwriting and claim talent, who work closely with our customers throughout the United States. Compensation plans are 
designed to reward profitability and shareholder value creation to better align compensation with the longer-term nature of insurance 
products and stakeholder expectations. Underwriters have the resources and authority to operate within established underwriting 
guidelines and share in the rewards when they succeed. We solicit employee feedback to help ensure employees are engaged, feel 
valued and are contributing to our success. 
 
The Company employed 1,147 associates throughout the United States as of December 31, 2024, compared to 1,099 as of 
December 31, 2023, and the average employee tenure was 8.6 years. We prefer to utilize our own underwriting, claims and support 
staff, given the complex nature of our products. The niche markets we operate within require unique experience and deep knowledge 
to select appropriate risks and serve our customers. Ensuring a seamless transfer of knowledge as employees retire and developing 

15 
newer talent continues to be a focus of the Company. We enable employees to maintain and expand their industry knowledge and 
technical expertise through education and training, as well as through memberships in industry and trade associations. We leverage the 
services of a limited number of third-party contractors when it is difficult to hire employees that address a needed skill set outside of 
our core insurance functions or when efficiencies can be gained. 
 
Human Capital Oversight 
 
At the board of directors level, oversight of human capital is provided by the Human Capital and Compensation Committee 
(HCCC). Executive oversight for human capital is provided by the Company’s Vice President of Human Resources, who reports to the 
President & CEO. Key responsibilities of the Vice President of Human Resources include providing effective programs related to 
staffing and succession planning, employee recruiting and development, compensation and benefits, and compliance, which are 
monitored by the HCCC. 
 
Compensation and Benefits 
 
We compensate employees through a competitive compensation (Total Rewards) program that includes a base salary or hourly 
wage, annual incentives for all full-time employees, long-term incentives for management, retirement benefits, as well as health, 
disability and life insurance. We utilize various information sources, including local, regional and national compensation surveys, to 
establish competitive pay targets for each position in the company to ensure our Total Rewards program attracts and retains a talented 
workforce. 
 
An important element of the Total Rewards program is to promote alignment of employee and shareholder interests, which is 
achieved through the Company’s Employee Stock Ownership Plan (ESOP) and long-term incentive plan (LTIP). The ESOP is a 
qualified retirement plan that provides shares of RLI Corp. stock to employees based on the profitability of the Company, while 
management is granted stock options and restricted stock units through the LTIP. Management, at the level of vice president and 
above, is subject to stock ownership guidelines requiring them to hold Company shares valued at a multiple of their base salary, 
depending on their role. As of December 31, 2024, 7 percent of RLI Corp. shares were owned by insiders. 
 
Diversity and Inclusion 
 
We strive to cultivate an exceptional workforce to perpetuate our ownership culture, deliver excellent customer service and 
continue to achieve superior business results. Our goal is to attract, develop and retain the best talent from diverse backgrounds, while 
promoting a culture where different viewpoints are valued and individuals feel respected, are treated fairly and have an opportunity to 
excel in their chosen careers. 
 
FORWARD LOOKING STATEMENTS 
 
Forward looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities 
Exchange Act of 1934 appear throughout this report. These forward looking statements generally include words such as “expect,” 
“predict,” “estimate,” “will,” “should,” “anticipate,” “believe” and similar expressions. Such assumptions are, in turn, based on 
information available and internal estimates and analyses of general economic conditions, competitive factors, conditions specific to 
the property and casualty insurance and reinsurance industries, claims development and the impact thereof on our loss reserves, the 
adequacy and financial security of our reinsurance programs, developments in the securities market and the impact on our investment 
portfolio, regulatory changes and conditions and other factors and are subject to various risks, uncertainties and other factors, 
including, without limitation those set forth below in “Item 1A Risk Factors.” Actual results could differ materially from those 
expressed in, or implied by, these forward looking statements. Forward looking statements reflect the Company’s expectations, plans 
or forecasts of future events and views as of the date of this report. While the Company may elect to update these forward looking 
statements at some point in the future, the Company specifically disclaims any obligation to do so. You should review the various 
risks, uncertainties and other factors listed from time to time in our Securities and Exchange Commission filings. 
 

16 
Item 1A. Risk Factors 
 
Insurance Industry 
 
Our results of operations and revenues may fluctuate as a result of many factors, including cyclical changes in the insurance 
industry, which may cause the price of our securities to be volatile. 
 
The results of operations of companies in the property and casualty insurance industry historically have been subject to 
significant fluctuations and uncertainties. Our profitability can be significantly affected, and has been affected to varying degrees, by: 
 
 
Competitive pressures impacting our ability to write new business or retain existing business at an adequate rate, 
 
 
Rising levels of loss costs that we cannot anticipate at the time we price our coverages, including those caused by 
inflation in the cost of materials, delays that cause increased business interruption losses and legal system abuse resulting 
in higher jury verdicts, 
 
 
Volatile and unpredictable developments, including man-made, weather-related and other natural catastrophes, terrorist 
attacks or geopolitical events, 
 
 
Significant price changes of the commodities we insure, 
 
 
Changes in the availability and level of reinsurance capacity, 
 
 
Changes in the amount of losses resulting from new types of claims, correlations of losses and new or changing judicial 
interpretations relating to the scope of insurers’ liabilities and 
 
 
The ability of our underwriters to accurately select and price risk and our claim personnel to appropriately deliver fair 
outcomes. 
 
In addition, the demand for property and casualty insurance, both admitted and excess and surplus lines, can vary significantly, 
rising as the overall level of economic activity increases and falling as that activity decreases, causing our revenues to fluctuate. These 
fluctuations in results of operations and revenues may not reflect long-term results and may cause the price of our securities to be 
volatile. 
 
A significant percentage of our premium revenues are sold through a few brokers and carrier partners and a loss of business 
provided by any of them could adversely affect us. 
 
We market our insurance products through brokers, agents and carrier partners. In 2024, 46 percent of our gross premiums 
written were produced through eight producer entities, while no other entity’s production exceeded 2 percent of our gross premiums 
written. Accordingly, our business is dependent on the willingness of these agents, brokers and carrier partners to recommend our 
products to their customers, who may also promote and distribute the products of our competitors. Loss of all or a substantial portion 
of the business written through these parties could have a material adverse effect on our business. 
 
Our business is concentrated in several key states and a change in our business in one of those states could disproportionately 
affect our financial condition or results of operations. 
 
Although we operate in all 50 states, 57 percent of our direct premiums earned were generated in four states in 2024: Florida – 
20 percent; California – 18 percent; Texas – 11 percent; and New York – 8 percent. An interruption in our operations, or a negative 
change in the business environment, insurance market or regulatory environment in one or more of these states could have a 
disproportionate effect on our business and direct premiums earned. 
 
We compete with a large number of companies in the insurance industry and their actions could ultimately impact our overall 
results. 
 
We are vulnerable to the actions of other companies who may seek to write business without the appropriate regard for risk and 
profitability, especially during periods of intense competition for premium. During these times, it is very difficult to grow or maintain 
premium volume without sacrificing underwriting income. 

17 
 
We face competition from specialty insurance companies, underwriting agencies and intermediaries, as well as diversified 
financial services companies that are significantly larger than we are, and that have significantly greater financial, marketing, 
management and other resources. We may also face competition from new sources of capital such as institutional investors seeking 
access to the insurance market, sometimes referred to as alternative capital, which may depress pricing or limit our opportunities to 
write business. Some of these competitors also have stronger brand awareness than we do. We may incur increased costs in competing 
for premium. If we are unable to compete effectively in the markets we operate in or are not successful in expanding our operations 
into new markets, the amount of premium we write may decline, pressuring overall business results. 
 
New, proposed or potential legislative or industry developments could further increase competition in our industry, including: 
 
 
An increasing level of industry capital, new carrier formation or elevated competition in our line of business,  
 
 
The deregulation of commercial insurance lines in certain states and the possibility of federal regulatory reform of the 
insurance industry, which could increase competition from standard carriers for our excess and surplus lines of insurance 
business, 
 
 
Programs in which state-sponsored entities provide property insurance in catastrophe-prone areas or other alternative 
market types of coverage, 
 
 
Changing practices, which may lead to greater competition in the insurance business and 
 
 
The development of new technologies, which may lead to disruption of current business models and the insurance value 
chain. 
 
New competition from these developments could cause the supply and/or demand for insurance or reinsurance to change, which 
could affect our ability to price our coverages at attractive rates and thereby adversely affect our underwriting results. 
 
A downgrade in our ratings from AM Best, Standard & Poor’s or Moody’s could negatively affect our business. 
 
Financial strength ratings are an important factor in establishing the competitive position of insurance companies. Our insurance 
companies are rated for overall financial strength by AM Best, Standard & Poor’s and Moody’s. AM Best, Standard & Poor’s and 
Moody’s ratings are independent opinions of an insurer’s financial strength and ability to meet ongoing insurance policy and contract 
obligations, based on a comprehensive quantitative and qualitative analysis of balance sheet strength, operating performance, business 
profile and enterprise risk management. These financial strength ratings are based on factors relevant to policyholders, agents, 
insurance brokers and intermediaries and are not specifically related to securities issued by the company. The view of required capital 
may differ between rating agencies, as well as from RLI Corp.’s own view of desired capital. Our ratings are subject to periodic 
review by such firms, and the criteria used in the rating methodologies is subject to change. As such, we cannot assure we will 
continue to maintain our current ratings. 
 
All our ratings were reviewed during 2024. AM Best reaffirmed its A+, Superior rating for the combined entity of RLI Ins., Mt. 
Hawley and CBIC (group-rated). Standard & Poor’s reaffirmed our A rating for the group of RLI Ins. and Mt. Hawley. Moody’s 
reaffirmed our group rating of A2 for RLI Ins. and Mt. Hawley. If our ratings are significantly reduced from their current levels by 
AM Best, Standard & Poor’s or Moody’s, our competitive position in the industry, and therefore our business, could be adversely 
affected. A significant downgrade could result in a substantial loss of business, as policyholders might move to other companies with 
greater financial strength ratings. 
 
We are subject to extensive governmental regulation, which may adversely affect our ability to achieve our business objectives. 
Moreover, if we fail to comply with these regulations, we may be subject to penalties, including fines and suspensions, which may 
adversely affect our financial condition, results of operations and reputation. 
 
Most insurance regulations are designed to protect the interests of policyholders rather than shareholders and other stakeholders. 
These regulations, generally administered by a department of insurance in each state and territory in which we do business, relate to, 
among other things: 
 
 
Approval of policy forms, premium rates and the basis on which rates can be determined, 
 

18 
 
The use of artificial intelligence systems to make or supplement decisions related to underwriting, rating and pricing, 
claim administration and payment, and fraud detection, 
 
 
Standards of solvency, including risk-based capital measurements, 
 
 
Licensing of insurers and their producers, 
 
 
Restrictions on agreements with our large revenue-producing agents, 
 
 
Cancellation and non-renewal of policies, 
 
 
Restrictions on the nature, quality and concentration of investments, 
 
 
Restrictions on the ability of our insurance company subsidiaries to pay dividends to the Company, 
 
 
Restrictions on transactions between insurance company subsidiaries and their affiliates, 
 
 
Restrictions on the size of risks insurable under a single policy, 
 
 
Requiring deposits for the benefit of policyholders, 
 
 
Requiring certain methods of accounting, 
 
 
Periodic examinations of our operations and finances, 
 
 
Prescribing the form and content of records of financial condition required to be filed and 
 
 
Requiring reserves for unearned premium, losses and other purposes. 
 
These regulatory requirements may adversely affect or inhibit our ability to achieve some or all of our business objectives. 
 
In addition, regulatory authorities have relatively broad discretion to deny or revoke licenses for various reasons, including the 
violation of regulations. In some instances, we follow practices based on our interpretations of regulations or practices that we believe 
may be generally followed by the industry. These practices may turn out to be different from the interpretations of regulatory 
authorities. If we do not have the requisite licenses and approvals or do not comply with applicable regulatory requirements, insurance 
regulatory authorities could initiate investigations or other proceedings, fine the Company, preclude or temporarily suspend the 
Company from carrying on some or all of its activities or otherwise penalize the Company. This could adversely affect our ability to 
operate our business. Further, changes in the level of regulation of the insurance industry or changes in laws or regulations themselves 
or interpretations by regulatory authorities could adversely affect our ability to operate our business as currently conducted. 
 
Our loss reserves are based on estimates and may be inadequate to cover our actual insured losses, which would negatively impact 
our profitability. 
 
Significant periods of time often elapse between the occurrence of an insured loss, the reporting of the loss to the Company and 
the payment of that loss. To recognize liabilities for unpaid losses, we establish reserves as balance sheet liabilities representing 
estimates of amounts needed to pay reported and unreported losses and the related loss adjustment expenses. Loss reserves are 
estimates of the ultimate cost of claims and do not represent an exact calculation of liability. These estimates are based on historical 
information and on estimates of future trends that may affect the frequency and severity of claims that may be reported in the future. 
 
Estimating loss reserves is a difficult, complex and an inherently uncertain process involving many variables and subjective 
judgments. Changes in industry practices, and in legal, legislative, regulatory, judicial, social and other conditions under which we 
operate may require us to pay claims we did not intend to cover when we wrote the policies. These changes may serve to extend the 
time for making claims, extend coverage and increase damages. These changes may not become apparent until after we have issued 
policies or bonds that are affected by the changes and, consequently, we may not know the extent of our liability and the impact to our 
financial performance until many years after a policy or bond was issued. The effects of these and other coverage issues are difficult to 
predict and could have a materially adverse effect on our financial performance. 
 

19 
As part of the reserving process, we review historical data and consider the impact of various factors such as: 
 
 
Loss emergence and claim reporting patterns, 
 
 
Underlying policy terms and conditions, 
 
 
Business and exposure mix, 
 
 
Emerging coverage issues, 
 
 
Trends in claim frequency and severity, 
 
 
Changes in operations, 
 
 
Economic trends such as inflation, 
 
 
State reviver statutes that permit claims after a statute of limitation has expired, 
 
 
Court closures or increased time-to-trial, 
 
 
Social trends such as increased amounts awarded by courts and juries and 
 
 
Changes in the regulatory and litigation environments. 
 
This process assumes that past experience, adjusted for the effects of current developments and anticipated trends, is an 
appropriate basis for predicting future events. It also assumes adequate historical or other data exists upon which to make these 
judgments. For more information on the estimates used in the establishment of loss reserves, see the Losses and Settlement Expenses 
section of our Critical Accounting Policies contained within Item 7, Management’s Discussion and Analysis of Financial Condition 
and Results of Operations. However, there is no precise method for evaluating the impact of any specific factor on the adequacy of 
reserves and actual results are likely to differ from original estimates. If the actual amount of insured losses is greater than the amount 
we have reserved for these losses, our profitability could suffer. 
 
Catastrophic losses are unpredictable and could cause the Company to suffer material financial losses. 
 
Our insurance coverages include exposure to catastrophic events, particularly hurricanes and tropical storms affecting coastal 
regions of the United States and earthquakes, primarily on the West Coast. Weather-related catastrophes may include events such as 
hurricanes, severe convective storms, winter weather, drought and heatwaves. In addition, catastrophe losses can occur from events 
such as wildfires, lava flows in Hawaii and terrorist events in the United States. 
 
The incidence and severity of catastrophes are inherently unpredictable. The extent of losses from a catastrophe is a function of 
both the total amount of insured values in the area affected by the event and the severity of the event. Most catastrophes are restricted 
to fairly specific geographic areas. However, hurricanes and earthquakes may produce significant damage in large, heavily populated 
areas. It is possible that a catastrophic event or multiple catastrophic events could cause the Company to suffer material financial 
losses. In addition, catastrophe claim costs may be higher than we originally estimate and could cause substantial volatility in our 
financial results for any fiscal quarter or year. 
 
We use models to help assess exposure to certain catastrophic events against established thresholds. Models include underlying 
assumptions based on a limited set of actual events and cannot contemplate all possible catastrophe scenarios. In addition, models are 
revised periodically, which could change modeled losses. The losses we might incur from an actual catastrophe could be higher than 
our expectation of losses generated from modeled catastrophe scenarios, which could have a materially adverse effect on our results of 
operations and financial condition. To address uncertainty related to catastrophe models, we also monitor against thresholds using 
non-modeled scenarios. 
 

20 
Changing climate and weather conditions may adversely affect our financial condition or profitability. 
 
Climate change is a complex and evolving issue and we cannot predict the cumulative impact it may have on our results of 
operations or financial condition at this time. The effects on the Company could include: 
 
 
Changes in the frequency, severity and location of weather-related catastrophes, which may result in higher levels of 
losses and could increase the volatility of our financial results, 
 
 
Additional uncertainty in third party catastrophe models, which could impair our ability to assess exposure and 
adequately price the catastrophe risks we insure, 
 
 
Flooding of coastal property, resulting from rising sea levels, making certain geographic areas uninhabitable, reducing 
demand for insurance products we offer in those areas, 
 
 
Increased losses from weather-related catastrophes may make it more difficult to obtain reinsurance at desired levels, or 
more expensive to acquire reinsurance coverage, which may reduce the amount of business we write and the revenues 
we generate, 
 
 
A transition from carbon-based energy to other sources of energy may decrease demand for insurance coverage we 
provide to the industries that produce or use carbon-based energy, decrease the availability of reinsurance available for 
coverages we provide for those industries, or increase claims and losses related to those industries, any of which could 
affect our profitability, 
 
 
Changes in legislation, regulation and court decisions could increase our compliance costs, impose liability on 
policyholders that we did not contemplate when we underwrote policies, or limit our ability to sell insurance coverage to 
certain policyholders and 
 
 
Losses on our invested assets that could have a material adverse impact on our results of operations and financial 
condition. 
 
If we cannot obtain adequate reinsurance protection for the risks we have underwritten or at prices we deem acceptable, we may be 
exposed to greater losses from these risks or we may reduce the amount of business we underwrite, which would reduce our 
revenues. 
 
Market conditions beyond our control determine the availability and cost of the reinsurance protection that we purchase. In 
addition, the historical results of reinsurance programs and the availability of capital also affect the availability of reinsurance. Our 
reinsurance agreements are generally subject to annual renewal. We cannot be sure that we can maintain our current reinsurance 
protection, obtain other reinsurance facilities in adequate amounts and at favorable rates, or diversify our exposure among an adequate 
number of high-quality reinsurance partners. If we are unable to renew our expiring facilities or obtain new reinsurance facilities on 
terms we deem acceptable, either our net loss exposures would increase, which could increase the volatility of our results, or we would 
have to reduce the level of our underwriting commitments when possible, which would reduce our revenues. Some of the bonds we 
issue, particularly in the energy sector, are non-cancelable and may expose the Company to greater losses, should the surety 
reinsurance coverage we are able to secure be reduced or become unavailable. Additionally, the potential exists for losses to exceed 
our reinsurance limits when we believe we have adequate reinsurance coverage in place, which would adversely impact our net 
earnings. 
 
Our reinsurers may not pay on losses in a timely fashion, or at all, which may increase our costs and have an adverse effect on our 
business. 
 
We purchase reinsurance to transfer part of the risk we have assumed (known as ceding) to a reinsurance company in exchange 
for part of the premium we receive in connection with the risk. Although reinsurance makes the reinsurer liable to the Company to the 
extent the risk is transferred or ceded to the reinsurer, it does not relieve the Company (the reinsured) of its liability to its 
policyholders. Accordingly, we bear credit risk with respect to our reinsurers. That is, our reinsurers may not pay claims made by the 
Company on a timely basis, or they may not pay some or all of these claims for a variety of reasons. Either of these events would 
increase our costs and could have a material adverse effect on our business. 
 

21 
Financial and Investment 
 
Adverse changes in the economy could lower the demand for our insurance products and could have an adverse effect on the 
revenue and profitability of our operations. 
 
Factors such as business revenue, construction spending, government spending, the volatility and strength of the capital markets 
and inflation can all affect the business and economic environment. These same factors affect our ability to generate revenue and 
profits. Insurance premiums in our markets are heavily dependent on our customer revenues, payroll, value of goods transported, miles 
traveled and number of new projects initiated. In an economic downturn characterized by higher unemployment, declines in 
construction spending and reduced corporate revenues, the demand for insurance products is adversely affected. Adverse changes in 
the economy may lead our customers to have less need or desire for insurance coverage, to cancel existing insurance policies, to 
modify coverage or to not renew with the Company, all of which affect our ability to generate revenue. In addition, as approximately a 
third of our business relates to the construction industry, our results of operations could be significantly impacted in an economic 
downturn if the construction industry is affected disproportionally. 
 
Access to capital and market liquidity may adversely affect our ability to take advantage of business opportunities as they arise. 
 
Our ability to grow our business depends, in part, on our ability to access capital when needed. We cannot predict capital market 
liquidity or the availability of capital. We also cannot predict the extent and duration of future economic and market disruptions, the 
impact of government interventions into the market to address these disruptions and their combined impact on our industry, business 
and investment portfolios. If our company needs capital but cannot raise it, our business and future growth could be adversely 
affected. 
 
We are an insurance holding company and therefore may not be able to receive adequate or timely dividends from our insurance 
subsidiaries. 
 
RLI Corp. is the holding company for our three insurance operating companies. At the holding company level, our principal 
assets are the shares of capital stock of our insurance company subsidiaries. We rely largely on dividends from our insurance company 
subsidiaries to meet our obligations for paying principal and interest on outstanding debt, corporate expenses and dividends to RLI 
Corp. shareholders. Dividend payments to RLI Corp. from our principal insurance subsidiary are restricted by state insurance laws as 
to the amount that may be paid without prior approval of the IDOI. As a result, we may not be able to receive dividends from such 
subsidiary at times and in amounts necessary to pay RLI Corp. obligations and desired dividends to shareholders. Ordinary dividends, 
which may be paid by our principal insurance subsidiary without prior regulatory approval, are subject to certain limitations based 
upon income, surplus and earned surplus. The maximum ordinary dividend distribution from our principal insurance subsidiary in a 
rolling 12-month period is limited by Illinois law to the greater of 10 percent of RLI Ins. policyholder surplus as of December 31 of 
the preceding year, or the net income of RLI Ins. for the 12-month period ending December 31 of the preceding year. Ordinary 
dividends are further restricted by the requirement that they be paid from earned surplus. Any dividend distribution in excess of the 
ordinary dividend limits is deemed extraordinary and requires prior approval (or non-disapproval) from the IDOI. Because the 
limitations are based upon a rolling 12-month period, the presence, amount and impact of these restrictions vary over time. 
 
We may not be able to, or might not choose to, continue paying dividends on our common stock. 
 
We have a history of paying regular, quarterly dividends and have paid annual special dividends since 2010. The payment of 
either type of dividend to our shareholders in the future is not guaranteed, is at the discretion of our board of directors and will depend 
on our results of operations, financial condition and other factors deemed relevant by our board of directors. Our ability to pay 
dividends depends largely on our subsidiaries’ earnings and operating capital requirements, and is subject to the regulatory, 
contractual and other constraints of our subsidiaries, including the effect of any such dividends or distributions on the AM Best rating 
or other ratings of our insurance subsidiaries. In addition, we may choose to retain capital to support growth or further mitigate risk, 
instead of returning excess capital to our shareholders. 
 
Our investment results and, therefore, our financial condition may be impacted by changes in the business, financial condition or 
operating results of the entities in which we invest, as well as changes in interest rates, government monetary policies, general 
economic conditions, liquidity and overall market conditions. 
 
We invest the premiums we receive from customers until they are needed to pay expenses or policyholder claims. Funds 
remaining after paying expenses and claims remain invested and are included in retained earnings. The value of our investment 
portfolio can fluctuate as a result of changes in the business, financial condition or operating results of the entities in which we invest. 
In addition, fluctuations can result from changes in interest rates, credit risk, government monetary policies, liquidity of holdings and 

22 
general economic conditions. The equity portfolio will fluctuate with movements in the overall stock market. While the equity 
portfolio has been constructed to have lower downside risk than the market, the portfolio is positively correlated with movements in 
domestic stocks. The bond portfolio is affected by interest rate changes and movement in credit spreads. We attempt to mitigate our 
interest rate and credit risks by constructing a well-diversified portfolio of high-quality securities with varied maturities. These 
fluctuations may negatively impact our financial condition. 
 
Operational 
 
Our success will depend on our ability to maintain and enhance effective operating procedures and manage risks on an enterprise-
wide basis. 
 
Operational risk and losses can result from, among other things, fraud, errors, failure to document transactions properly, failure 
to obtain proper internal authorization, failure to comply with regulatory requirements, information technology failures or external 
events. We continue to enhance our operating procedures and internal controls to effectively support our business and our regulatory 
and reporting requirements. The NAIC and state legislatures have increased their focus on risks within an insurer’s holding company 
system that may pose enterprise risk to insurers. The Illinois legislature has adopted the Risk Management and Own Risk and 
Solvency Assessment (ORSA) Law, which requires domestic insurers to maintain a risk management framework and establishes a 
legal requirement for domestic insurers to conduct an ORSA in accordance with the NAIC’s ORSA Guidance Manual. The ORSA 
Law also provides that, no less than annually, an insurer must submit an ORSA summary report. Under the Illinois insurance holding 
company laws, on an annual basis, we are also required to file an enterprise risk report with the IDOI, which is intended to identify the 
material risks within our insurance holding company system that could pose enterprise risk to our insurance company subsidiaries. We 
operate within an enterprise risk management (ERM) framework designed to assess and monitor our risks. However, assurance that 
we can effectively review and monitor all risks or that all our employees will operate within the ERM framework cannot be 
guaranteed. Assurances that our ERM framework will result in the Company accurately identifying all risks and accurately limiting 
our exposures based on our assessments also cannot be guaranteed. 
 
We may not be able to effectively start up or integrate new product opportunities. 
 
Our ability to grow our business depends, in part, on our creation, implementation or acquisition of new insurance products that 
are profitable and fit within our business model. Our ability to grow profitably requires that we identify market opportunities, which 
may include acquisitions, and that we attract and retain underwriting and claims expertise to support that growth. New product 
launches, as well as resources to integrate business acquisitions are subject to many obstacles, including ensuring we have sufficient 
business and system processes, determining appropriate pricing, obtaining reinsurance, assessing opportunity costs and regulatory 
burdens and planning for internal infrastructure needs. If we cannot effectively or accurately assess and overcome these obstacles, or 
we improperly implement new insurance products, our ability to grow profitably could be impaired. 
 
We may be unable to attract and retain qualified key employees. 
 
We depend on our ability to attract and retain experienced underwriting and claim talent, who have deep knowledge of the niche 
business we write, and other skilled employees. If we cannot attract or retain top-performing executive officers, underwriters and other 
employees, the quality of their performance decreases or we fail to implement succession plans for our key employees, we may be 
unable to maintain our current competitive position in the markets in which we operate or expand our operations into new markets. 
 
We rely on third-party vendors for a number of key components of our business. 
 
We contract with a number of third-party vendors to support our business. For example, we have license agreements for 
software that we use to model natural catastrophes, process claims, and manage policies, producers and financial processes. The 
vendors range from large national companies, who are dominant in their area of expertise and would be difficult to quickly replace, to 
smaller or start-up vendors with leading technology, but with shorter operating histories and fewer financial resources. Failures of 
certain vendors to provide services could adversely affect our ability to deliver products and services to our customers, disrupting our 
business and causing the Company to incur significant expense. If one or more of our vendors fail to protect personal information of 
our customers, claimants or employees, we may incur operational impairments, or could be exposed to litigation, compliance costs or 
reputational damage. We maintain a vendor management program to establish procurement policies and to monitor vendor risk, 
including the security and stability of our critical vendors. 
 

23 
Any significant interruption in the operation of our facilities, systems and business functions could adversely affect our financial 
condition and results of operations. 
 
We rely on multiple computer systems to interact with producers and customers, issue policies, pay claims, run modeling 
functions, assess insurance risks and complete various important internal processes including accounting and bookkeeping. Our 
business is highly dependent on our ability to access these systems to perform necessary business functions. Additionally, some of 
these systems may include or rely upon third-party systems not located on our premises. Any of these systems may be exposed to 
unplanned interruption, unreliability or intrusion from a variety of causes, including among others, storms and other natural disasters, 
terrorist attacks, cyber attacks, utility outages or complications encountered as existing systems are replaced or upgraded. 
 
Any such issues could materially impact our company, including the impairment of information availability, compromise of 
system integrity/accuracy, misappropriation of confidential information, reduction of our volume of transactions and interruption of 
our general business. Although we believe our computer systems are secure and continue to take steps to ensure they are protected 
against such risks, we cannot guarantee such problems will not occur. If they do, interruption to our business and damage to our 
reputation and related costs, could be significant, which could impair our profitability. 
 
Technology breaches or failures, including but not limited to cyber security incidents, could disrupt our operations, result in the 
loss of critical and confidential information and expose us to additional liabilities, which could adversely impact our reputation 
and results of operations. 
 
Global cyber security threats can range from uncoordinated individual attempts to gain unauthorized access to our information 
technology systems, and those of our business or service providers, to sophisticated and targeted measures known as advanced 
persistent threats. Like other companies, RLI Corp. is also subject to insider threats that may impact the confidentiality, integrity or 
availability of our data. We, as well as our business partners and service providers, employ measures to prevent, detect, address, 
mitigate and recover from these threats (including employee training, access controls, data encryption, vulnerability assessments, 
continuous monitoring of information technology networks and systems and maintenance of backup and protective systems). 
However, cyber security incidents, depending on their nature and scope, could potentially result in the misappropriation, destruction, 
corruption or unavailability of critical data and confidential or proprietary information (our own or that of third parties) and the 
disruption of business operations. Security breaches could expose the Company to a risk of loss or misuse of Company or third-party 
confidential information, litigation and potential liability. In addition, cyber incidents that impact the availability, reliability, speed, 
accuracy or other proper functioning of our technology systems could impact our operations. We may not have the resources or 
technical sophistication to anticipate or prevent every type of cyber attack. A significant cyber incident, including system failure, 
security breach, disruption by malware or other damage could interrupt or delay our operations, result in a violation of applicable 
privacy and other laws, damage our reputation, cause a loss of customers or give rise to remediation costs, monetary fines and other 
penalties, which could be significant. We have cyber insurance, but it is possible that the coverage we have in place would not entirely 
protect the Company in the event that we experienced a cyber security incident, interruption or widespread failure of our information 
technology systems. 
 
If we are unable to keep pace with the technological advancements in the insurance industry, our ability to compete effectively 
could be impaired. 
 
Our operations rely upon complex and expensive information technology systems for interacting with policyholders, brokers 
and other business partners. The pace at which information systems must be upgraded is continually increasing, requiring an ongoing 
commitment of significant resources to maintain or upgrade to current standards and serve our customers. If we are unable to keep 
pace with the advancements being made in technology, such as the use of artificial intelligence systems, our ability to compete with 
other insurance companies who have advanced technological capabilities will be negatively affected. Furthermore, if we are unable to 
effectively update or replace our key legacy technology systems as they become obsolete, or as emerging technology renders them 
competitively inefficient, our competitive position, security and our cost structure could be adversely affected. 
 
Epidemics, pandemics and public health outbreaks could adversely affect our business, including revenues, profitability, results of 
operations and/or cash flows, in a manner and to a degree that could be material. 
 
Epidemics, pandemics and other public health outbreaks generally result in significant disruptions in economic activity and 
financial markets. The cumulative effects on the Company could include, without limitation: 
 
 
Reduced demand for our insurance policies due to reduced economic activity, which could negatively impact our 
revenues, 
 

24 
 
Reduced cash flows from our policyholders, delaying premium payments, 
 
 
Increased costs and disruption of operations due to employees working remotely or unavailability of our employees, 
 
 
Increased claims, losses, litigation and related expenses, 
 
 
Legislative, regulatory and judicial actions in response to the public health outbreak, including, but not limited to, actions 
prohibiting us from cancelling insurance policies in accordance with our policy terms, requiring us to cover losses when 
our underwriting intent in those policies was not to provide coverage or was to exclude coverage, ordering us to provide 
premium refunds, granting extended grace periods for payment of premiums and providing for extended periods of time 
to pay premiums that are past due, 
 
 
Policyholder losses from pandemic-related claims could be greater than our reserves for those losses, 
 
 
Volatility and declines in financial markets could reduce the fair market value, or result in the impairment, of invested 
assets held by the Company and 
 
 
Changes in interest rates, which could reduce future investment results. 
 
Although we have investigated and closed a substantial number of COVID-19-related claims without payment, state and federal 
courts could rule that such claims are covered under our policies. Court decisions upholding our position that these COVID-19 related 
claims are not covered under our policies could also be overturned on appeal. These actions could result in an increase in claims and 
paid losses, which could have a materially adverse effect on our financial performance. Such appellate court decisions may take 
several years to become final and their ultimate outcome remains uncertain at this time. 
 
We may suffer losses from litigation, which could materially and adversely affect our financial condition and business operations. 
 
We continually face risks associated with litigation of various types, including general commercial and corporate litigation, and 
disputes relating to bad faith allegations that could result in the Company incurring losses in excess of policy limits. We are party to a 
variety of litigation matters throughout the year. Litigation is subject to inherent uncertainties, and if there were an unfavorable 
outcome, it could have a material adverse impact on our results of operations and financial position in the period in which the outcome 
occurs. Even if an unfavorable outcome does not materialize, we still may face substantial expense and disruption associated with the 
litigation. 
 
Anti-takeover provisions affecting the Company could prevent or delay a change of control that is beneficial to you. 
 
Provisions of our certificate of incorporation and by-laws, as well as applicable Delaware law, federal and state regulations and 
insurance company regulations may discourage, delay or prevent a merger, tender offer or other change of control that holders of our 
securities may consider favorable. Some of these provisions impose various procedural and other requirements that could make it 
more difficult for shareholders to affect certain corporate actions. These provisions could: 
 
 
Have the effect of delaying, deferring or preventing a change in control of the Company, 
 
 
Discourage bids for our securities at a premium over the market price, 
 
 
Adversely affect the market price, the voting and other rights of the holders of our securities or 
 
 
Impede the ability of the holders of our securities to change our management. 
 
In particular, we are subject to Section 203 of the Delaware General Corporation Law which, under certain circumstances, 
restricts our ability to engage in a business combination, such as a merger or sale of assets, with any shareholder that, together with 
affiliates, owns 15 percent or more of our common stock, which similarly could prohibit or delay the accomplishment of a change of 
control transaction.

Item 1C. Cybersecurity 
 
Risks from cybersecurity threats or incidents (cybersecurity risks) are assessed, identified and managed by the Company in a 
manner that is consistent with leading cybersecurity frameworks, including the National Institute of Standards and Technology 
Cybersecurity Framework (NIST Framework). The Company’s approach to cybersecurity risk management is generally based on the 
six core functions contained within the NIST Framework organizing structure: identify, protect, detect, respond, recover and govern. 
 
As of the date of this report, risks from cybersecurity threats or incidents have not materially affected, nor are they reasonably 
likely to materially affect, the Company’s business strategy, results of operations or financial condition. However, in light of emerging 
and changing cybersecurity threats and vulnerabilities, the Company cannot guarantee that it will not be a victim of a cybersecurity 
attack in the future that could materially affect the Company. See Item 1A, Risk Factors for more information. 
 
The IT security department is responsible for the day-to-day assessment and management of cybersecurity risks, including 
efforts to prevent and, if necessary, mitigate the effects of a cybersecurity incident. The Company’s IT security department operates 
under general oversight of the Company’s chief information officer (CIO), who also serves as the Company’s chief information 
security officer (CISO). The Company’s CIO has 27 years of technology and technology leadership experience, including 14 years 
serving as a CISO, in the insurance industry. The head of the Company’s IT security department, who reports to the CIO, holds a 
Certified Information Systems Security Professional designation from the Information Security Certification Consortium, has 20 years 
of experience in the insurance industry and has served in IT security-related roles for 24 years. 
 
Management oversight of cybersecurity risks is provided primarily through the Company’s Technology Committee, which is 
chaired by the Company’s CIO and comprised of members of senior management. The Technology Committee’s responsibilities 
include general oversight of cybersecurity-related matters, maintenance of the cybersecurity and data privacy programs and oversight 
of the Company’s cybersecurity incident response plan. Technology risk, including cybersecurity risk, is also integrated into the 
Company’s enterprise risk management process. The Company’s Risk Committee, chaired by the CEO and comprised of members of 
executive management, identifies the Company’s material risks and reviews the strategies, processes and controls in place to facilitate 
the understanding, identification, prevention, measurement, reporting and mitigation of those risks. The Risk Committee meets 
quarterly and reviews the Technology Committee’s current assessment of cybersecurity risks.  
 
Through 2024, the RLI Corp. Board of Directors provided oversight for cybersecurity risks primarily through its Audit 
Committee. In February 2025, the charter of the Finance & Investments Committee was revised to include overall enterprise risk 
management oversight, including oversight of cybersecurity risk. The committee was renamed the Finance & Risk Committee (FRC). 
The Company’s CIO, along with the head of the Company’s IT security department, presents quarterly to the designated committee on 
cybersecurity risks and the Company’s strategies to assess and manage those risks. Additionally, the board receives periodic updates 
on emerging cybersecurity issues and developments through director education provided by the Company and third-party experts, 
detailed reviews provided by the CIO and the Company’s head of IT security on select cybersecurity topics, and periodic “table top” 
simulations of a cybersecurity event. 
 
The Company maintains a Cybersecurity Incident Response Plan (CIRP) providing a framework for identifying, evaluating and 
escalating potential or actual cybersecurity events. The CIRP assigns responsibilities and provides a workflow between the 
Company’s IT security department; the Company’s Technology Committee; and the board of directors regarding the detection, 
assessment and response to a cybersecurity event. 
 
The Company’s internal audit department routinely engages third-party cybersecurity consultants to conduct network security 
audits. The Company also engages other third-party consultants in a number of areas to support the assessment, identification and 
management of cybersecurity risks, including risk assessments, log monitoring, threat intelligence, system penetration testing, training 
and incident response, among others. The Company performs cybersecurity due diligence and monitoring of third-party vendors, 
which may include the review of System and Organization Control (SOC) reports or the results of a security questionnaire, to identify 
the cybersecurity controls and protections maintained by a third party.  
 
Item 2. Properties 
 
We own five commercial buildings totaling 173,000 square feet on our 23-acre campus that serves as our corporate headquarters 
in Peoria, Illinois. All our branch offices and other company operations lease office space throughout the country. Management 
considers our office facilities suitable and adequate for our current levels of operations.

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities 
 
RLI Corp. common stock trades on the New York Stock Exchange under the symbol “RLI”. RLI Corp. has paid dividends for 
194 consecutive quarters and increased quarterly dividends in each of the last 49 years. In December 2024 and 2023, RLI Corp. paid 
special cash dividends of $2.00 and $1.00 per share to shareholders, respectively. As of February 13, 2025, there were 1,103 registered 
holders of the Company’s common stock. 
 
The payment of dividends to our shareholders is at the discretion of our board of directors and will depend on our results of 
operations, our financial condition, regulatory restrictions of our insurance subsidiaries and other factors deemed relevant by our board 
of directors. Although the Company currently intends to continue paying quarterly cash dividends to our shareholders, there can be no 
assurance as to the amount of such dividends or whether the Company will continue to pay such dividends.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations 
 
OVERVIEW 
 
RLI Corp. is a U.S. based, specialty insurance company that underwrites select property, casualty and surety products through 
three major subsidiaries collectively known as RLI Insurance Group (Group). Our focus is on niche markets and developing unique 
products that are tailored to customers’ needs. We hire underwriters and claim examiners with deep expertise and provide exceptional 
customer service and support. We maintain a highly diverse product portfolio and underwrite for profit in all market conditions. In 
2024, we achieved our 29th consecutive year of underwriting profitability. Over the 29-year period, we averaged an 88.1 combined 
ratio. This drives our ability to provide shareholder returns in three different ways: the underwriting income itself, net investment 
income from our investment portfolio and long-term appreciation in our equity portfolio. 
 
On December 15, 2025, RLI Corp. effected a two-for-one split of its common stock and a proportionate increase in the number 
of authorized shares. All share and per share information throughout this report has been retroactively adjusted to reflect the stock 
split. 
 
We measure the results of our insurance operations by monitoring growth and profitability across three distinct business 
segments: property, casualty and surety. Growth is measured in terms of gross premiums written, and profitability is analyzed through 
underwriting income and combined ratios. 
 
KEY PERFORMANCE MEASURES 
 
Following is a list of key performance measures found throughout this report with their definitions, relationships to GAAP 
measures and explanations of their importance to our operations. 
 
Underwriting Income 
 
Underwriting income or profit represents one measure of the pretax profitability of our insurance operations and is derived by 
subtracting losses and settlement expenses, policy acquisition costs and insurance operating expenses from net premiums earned, 
which are all GAAP financial measures. Each of these components are presented in the statements of earnings but are not subtotaled. 
However, this information is available in total and by segment in note 11 to the consolidated financial statements within Item 8, 
Financial Statements and Supplementary Data. The nearest comparable GAAP measure is earnings before income taxes which, in 
addition to underwriting income, includes net investment income, net realized gains or losses, net unrealized gains or losses on equity 
securities, general corporate expenses, debt costs and our portion of earnings from unconsolidated investees. A reconciliation of net 
earnings to underwriting income follows:

Combined Ratio 
 
The combined ratio, which is derived from components of underwriting income, is a common industry performance measure of 
profitability for underwriting operations and is calculated in two components. The loss ratio is loss and settlement expenses divided by 
net premiums earned. The expense ratio reflects the sum of policy acquisition costs and insurance operating expenses divided by net 
premiums earned. All items included in these components of the combined ratio are presented in our GAAP consolidated financial 
statements. The sum of the loss and expense ratios is the combined ratio. The difference between the combined ratio and 100 reflects 
the per-dollar rate of underwriting income or loss. 
 

29 
CRITICAL ACCOUNTING POLICIES 
 
In preparing the consolidated financial statements, we are required to make estimates and assumptions that affect the reported 
amounts of assets and liabilities and the disclosures of contingent assets and liabilities as of the date of the consolidated financial 
statements and the reported amounts of revenues and expenses for the reporting period. Actual results could differ significantly from 
those estimates. 
 
The most critical accounting policies involve significant estimates and include those used in determining the liability for unpaid 
losses and settlement expenses, investment valuation, recoverability of reinsurance balances, deferred policy acquisition costs and 
deferred taxes. 
 
LOSSES AND SETTLEMENT EXPENSES 
 
Overview 
 
Loss and loss adjustment expense (LAE) reserves represent our best estimate of ultimate payments for losses and related 
settlement expenses from claims that have been reported but not paid, and those losses that have been incurred but not yet reported 
(IBNR) to the Company. Loss reserves do not represent an exact calculation of liability, but instead represent our estimates, generally 
utilizing individual claim estimates, actuarial expertise and estimation techniques at a given accounting date. The loss reserve 
estimates are expectations of what ultimate settlement and administration of claims will cost upon final resolution. These estimates are 
based on facts and circumstances then known to the Company, review of historical settlement patterns, estimates of trends in claim 
frequency and severity, projections of loss costs, expected interpretations of legal theories of liability and many other factors. In 
establishing reserves, we also consider estimated recoveries from reinsurance as well as salvage and subrogation. 
 
We record two categories of loss and LAE reserves: case-specific reserves and IBNR reserves. Within a reasonable period of 
time after a claim is reported, our claim department completes an initial investigation and establishes a case reserve. This case-specific 
reserve is an estimate of the ultimate amount we will have to pay for the claim, including related legal expenses and other costs 
associated with resolving and settling it. The estimate reflects all of the current information available regarding the claim, the 
informed judgment of our professional claim personnel regarding the nature and value of the specific type of claim and our reserving 
practices. During the life cycle of a particular claim, as more information becomes available, we may revise the estimate of the 
ultimate value of the claim either upward or downward. We may determine that it is appropriate to pay portions of the reserve to the 
claimant or related settlement expenses before final resolution of the claim. The amount of the individual case reserve will be adjusted 
accordingly and is based on the most recent information available. 
 
We establish IBNR reserves to estimate the amount we will have to pay for claims that have occurred, but have not yet been 
reported to the Company, claims that have been reported to the Company that may ultimately be paid out differently than reflected in 
our case-specific reserves and claims that have been closed but may reopen and require future payment. 
 
LAE represents the cost involved in adjusting and administering losses from policies we issued. The LAE reserves are 
frequently separated into two components: allocated and unallocated. Allocated loss adjustment expense (ALAE) reserves represent an 
estimate of claims settlement expenses that can be identified with a specific claim. Examples of ALAE would be the hiring of an 
outside adjuster to investigate a claim or an outside attorney to defend our insured. The claim adjuster typically estimates this cost 
separately from the loss component in the case reserve. Unallocated loss adjustment expense (ULAE) reserves represent an estimate of 
claims settlement expenses that cannot be identified with a specific claim. An example of ULAE would be the cost of an internal 
claim examiner to manage or investigate claims. 
 
The process of estimating loss reserves involves a high degree of judgment and is subject to a number of variables. These 
variables can be affected by both internal and external events, such as changes in claim handling procedures, claim personnel, 
economic inflation, legal trends and legislative changes, among others. The impact of many of these items on ultimate costs for loss 
and LAE is difficult to estimate. Loss reserve estimations also differ significantly by coverage due to differences in claim complexity, 
the volume of claims, the policy limits written, the terms and conditions of the underlying policies, the potential severity of individual 
claims, the determination of occurrence date for a claim and reporting lags (the time between the occurrence of the policyholder event 
and when it is actually reported to the insurer). Informed judgment is applied throughout the process. We continually refine our loss 
reserve estimates as historical loss experience develops and additional claims are reported and settled. We rigorously attempt to 
consider all significant facts and circumstances known at the time loss reserves are established. 
 

30 
Following is a table of significant risk factors involved in estimating losses grouped by major product line. We distinguish 
between loss ratio risk and reserve estimation risk. Loss ratio risk refers to the possible dispersion of loss ratios from year to year due 
to inherent volatility in the business, such as high severity or aggregating exposures. Reserve estimation risk recognizes the difficulty 
in estimating a given year’s ultimate loss liability. As an example, our property catastrophe business (included below in commercial 
and other property) has significant variance in year over year results; however, its reserving estimation risk is relatively moderate.

Due to inherent uncertainty underlying loss reserve estimates, including, but not limited to, the future settlement environment, 
final resolution of the estimated liability may be different from that anticipated at the reporting date. The amount by which current 
estimated losses differ from those estimated for a period at a prior valuation date is known as development. Development is 
unfavorable when the losses ultimately settle for more than the levels at which they were reserved or subsequent estimates indicate a 
basis for reserve increases on unresolved claims. Development is favorable when losses ultimately settle for less than the amount 
reserved or subsequent estimates indicate a basis for reducing loss reserves on unresolved claims. We reflect favorable or unfavorable 
development of loss reserves in the results of operations in the period the estimates are changed. 
 

31 
Our IBNR reserving process involves three steps: (1) an initial IBNR generation process that is prospective in nature, (2) a loss 
and LAE reserve estimation process that occurs retrospectively and (3) a subsequent discussion and reconciliation between our 
prospective and retrospective IBNR estimates, which includes changes in our provisions for IBNR where deemed appropriate. 
 
Initial IBNR Generation Process 
 
Initial carried IBNR reserves are determined through a reserve generation process. The intent of this process is to establish an 
initial total reserve that will provide a reasonable provision for the ultimate value of all unpaid loss and ALAE liabilities. For most 
casualty and surety products, this process involves the use of an initial loss and ALAE ratio that is applied to the earned premium for a 
given period. The result is our best initial estimate of the expected amount of ultimate loss and ALAE for the period by product. 
Payments and case reserves are subtracted from this initial estimate of ultimate loss and ALAE to determine a carried IBNR reserve. 
 
For certain property products, we use an alternative method of determining an appropriate provision for initial IBNR. Since this 
segment is characterized by a shorter period of time between claim occurrence and claim settlement, the IBNR reserves are 
determined by IBNR percentages applied to premium earned. The percentages are determined based on expected loss ratios and loss 
development assumptions. The loss development assumptions are typically based on historical reporting patterns but could consider 
alternative sources of information. The IBNR percentages are reviewed and updated periodically. No deductions for paid or case 
reserves are made. This alternative method of determining initial IBNR allows incurred losses and ALAE to react more rapidly to the 
actual emergence, and is more appropriate for our property products where final claim resolution occurs over a shorter period of time. 
 
We do not reserve for natural or man-made catastrophes until an event has occurred. Shortly after such occurrence, we review 
insured locations exposed to the event. We also consider our knowledge of frequency and severity from early claim reports and onsite 
reviews of damage to determine an appropriate reserve for the catastrophe. These reserves are reviewed frequently to consider actual 
losses reported and appropriate changes to our estimates are made to reflect the new information. 
 
The initial loss and ALAE ratios that are applied to earned premium are reviewed at least semi-annually. Prospective estimates 
are made based on historical loss experience adjusted for exposure mix, price change and loss cost trends. The initial loss and ALAE 
ratios also reflect our judgment as to estimation risk. We consider estimation risk by product and coverage within product, if 
applicable. A product with greater volatility and uncertainty has greater estimation risk. Products or coverages with higher estimation 
risk include, but are not limited to, the following characteristics: 
 
 
Significant changes in underlying policy terms and conditions, 
 
 
A new business or one experiencing significant growth and/or high turnover, 
 
 
Small volume or lacking internal data requiring significant utilization of external data, 
 
 
Unique reinsurance features including those with aggregate stop-loss, reinstatement clauses, commutation provisions or 
clash protection, 
 
 
Longer emergence patterns with exposures to latent unforeseen mass tort, 
 
 
Assumed reinsurance businesses where there is an extended reporting lag and/or a heavier utilization of ceding company 
data and claims and product expertise, 
 
 
High severity and/or low frequency, 
 
 
Operational processes undergoing significant change and/or 
 
 
High sensitivity to significant swings in loss trends, economic change or judicial change. 
 
The historical and prospective loss and ALAE estimates, along with the risks listed, are the basis for determining our initial and 
subsequent carried reserves. Adjustments in the initial loss ratio by product and segment are made where necessary and reflect updated 
assumptions regarding loss experience, loss trends, price changes and prevailing risk factors. 
 

32 
Loss and LAE Reserve Estimation Process 
 
Estimates of the expected value of the unpaid loss and LAE are derived using standard actuarial methodologies on a quarterly 
basis. In addition, an emergence analysis is completed quarterly to determine if further adjustments are necessary. These estimates are 
then compared to the carried loss reserves to determine the appropriateness of the current reserve balance. 
 
The process of estimating ultimate payment for claims and claim expenses begins with the collection and analysis of current and 
historical claim data. Data on individual reported claims, including paid amounts and individual claim adjuster estimates, are grouped 
by common characteristics. There is judgment involved in this grouping. Considerations when grouping data include the volume of the 
data available, the credibility of the data available, the homogeneity of the risks in each grouping and both settlement and payment 
pattern consistency. We use this data to determine historical claim reporting and payment patterns, which are used in the analysis of 
ultimate claim liabilities. In some analyses, including businesses without sufficiently large numbers of policies or that have not 
accumulated sufficient historical statistics, our own data is supplemented with external or industry average data as available and when 
appropriate. For liabilities arising out of directors and officers, management liability and workers’ compensation, we utilize external 
data extensively. 
 
We also incorporate estimated losses relative to premium (loss ratios) by year into the analysis. The expected loss ratios are 
based on a review of historical loss performance, trends in frequency and severity and price level changes. The estimates are subject to 
judgment including consideration given to available internal and industry data, growth and policy turnover, changes in policy limits, 
changes in underlying policy provisions, changes in legal and regulatory interpretations of policy provisions and changes in 
reinsurance structure. For the most current year, these are equivalent with the ratios used in the initial IBNR generation process. 
Increased recognition is given to actual emergence as the years age. 
 
We use historical development patterns, expected loss ratios and standard actuarial methods to derive an estimate of the ultimate 
level of loss and LAE payments necessary to settle all the claims occurring as of the end of the evaluation period. 
 
Our reserve processes include multiple standard actuarial methods for determining estimates of IBNR reserves. Other 
supplementary methodologies are incorporated as necessary. Mass tort and latent liabilities are examples of exposures for which 
supplementary methodologies are used. Each method produces an estimate of ultimate loss by accident year. We review all of these 
various estimates and assign weights to each based on the characteristics of the product being reviewed. 
 
The methodologies we have chosen to incorporate are a function of data availability and are reflective of our own book of 
business. From time to time, we evaluate the need to add supplementary methodologies. New methods are incorporated if it is 
believed they improve the estimate of our ultimate loss and LAE liability. All of the actuarial methods eventually converge to the 
same estimate as an accident year matures. Our core methodologies are listed below with a short description and their relative 
strengths and weaknesses: 
 
Paid Loss Development — Historical payment patterns for prior claims are used to estimate future payment patterns for current 
claims. These patterns are applied to current payments by accident year to yield an expected ultimate loss. 
 
Strengths:  The method reflects only the claim dollars that have been paid and is not subject to case-basis reserve changes or 
changes in case reserve practices. 
 
Weaknesses:  External claims environment changes can impact the rate at which claims are settled and losses paid (e.g. increase 
in attorney involvement or change in legal precedent). Adjustments to reflect changes in payment patterns on a prospective basis are 
difficult to quantify. For losses that have occurred recently, payments can be minimal and thus early estimates are subject to 
significant instability. 
 
Incurred Loss Development — Historical case-incurred patterns (paid losses plus case reserves) for past claims are used to 
estimate future case-incurred amounts for current claims. These patterns are applied to current case-incurred losses by accident year to 
yield an expected ultimate loss. 
 
Strengths:  Losses are reported more quickly than paid, therefore, the estimates stabilize sooner. The method reflects more 
information in the analysis than the paid loss development method. 
 
Weaknesses:  Method involves additional estimation risk if significant changes to case reserving practices have occurred. 
 

33 
Case Reserve Development — Patterns of historical development in reported losses relative to historical case reserves are 
determined. These patterns are applied to current case reserves by accident year and the result is combined with paid losses to yield an 
expected ultimate loss. 
 
Strengths:  Like the incurred development method, this method benefits from using the additional information available in case 
reserves that is not available from paid losses only. It also can provide a more reasonable estimate than other methods when the 
proportion of claims still open for an accident year is unusually high or low. 
 
Weaknesses:  It is subject to the risk of changes in case reserving practices or philosophy. It may provide unstable estimates 
when an accident year is immature and more of the IBNR is expected to come from unreported claims rather than development on 
reported claims and when accident years are very mature with infrequent case reserves. 
 
Expected Loss Ratio — Historical loss ratios, in combination with projections of frequency and severity trends, as well as 
estimates of price and exposure changes, are analyzed to produce an estimate of the expected loss ratio for each accident year. The 
expected loss ratio is then applied to the earned premium for each year to estimate the expected ultimate losses. The current 
accident year expected loss ratio is also the prospective loss and ALAE ratio used in our initial IBNR generation process. 
 
Strengths:  Reflects an estimate independent of how losses are emerging on either a paid or a case reserve basis. This method is 
particularly useful in the absence of historical development patterns or where losses take a long time to emerge. 
 
Weaknesses:  Ignores how losses are actually emerging and thus produces the same estimate of ultimate loss regardless of 
favorable/unfavorable emergence. 
 
Paid and Incurred Bornhuetter/Ferguson (BF) — This approach blends the expected loss ratio method with either the paid or 
incurred loss development method. In effect, the BF methods produce weighted average indications for each accident year. As an 
example, if the current accident year for commercial automobile liability is estimated to be 20 percent paid, then the paid loss 
development method would receive a weight of 20 percent and the expected loss ratio method would receive an 80 percent weight. 
Over time, this method will converge with the ultimate estimated by the respective loss development method. 
 
Strengths:  Reflects actual emergence that is favorable/unfavorable, but assumes remaining emergence will continue as 
previously expected. Does not overreact to the early emergence (or lack of emergence) where patterns are most unstable. 
 
Weaknesses:  Could potentially understate favorable or unfavorable development by putting weight on the expected loss ratio. 
 
In most cases, multiple estimation methods will be valid for the particular facts and circumstances of the claim liabilities being 
evaluated. Each estimation method has its own set of assumption variables and its own advantages and disadvantages, with no single 
estimation method being better than the others in all situations, and no one set of assumption variables being meaningful for all 
product line components. The relative strengths and weaknesses of the particular estimation methods, when applied to a particular 
group of claims, can also change over time. Therefore, the weight given to each estimation method will likely change by accident year 
and with each evaluation. 
 
The actuarial central estimates typically follow a progression that places significant weight on the BF methods when 
accident years are younger and claim emergence is immature. As accident years mature and claims emerge over time, increasing 
weight is placed on the incurred development method, the paid development method and the case reserve development method. For 
product lines with faster loss emergence, the progression to greater weight on the incurred and paid development methods occurs more 
quickly. 
 
For our long and medium-tail products, the BF methods are typically given the most weight for more evaluation periods than the 
short-tailed lines. These methods are also predominant for the first 12 months of evaluation for short-tail lines. Beyond these time 
periods, our actuaries apply their professional judgment when weighting the estimates from the various methods deployed, but place 
significant reliance on the expected stage of development in normal circumstances. 
 
Judgment can supersede this natural progression if risk factors and assumptions change, or if a situation occurs that amplifies a 
particular strength or weakness of a methodology. Extreme projections are critically analyzed and may be adjusted, given less 
credence or discarded altogether. Internal documentation is maintained that records any substantial changes in methods or assumptions 
from one loss reserve study to another. 
 

34 
Our estimates of ultimate loss and LAE reserves are subject to change as additional data emerges. This could occur as a result of 
change in loss development patterns, a revision in expected loss ratios, the emergence of exceptional loss activity, a change in 
weightings between actuarial methods, the addition of new actuarial methodologies, new information that merits inclusion or the 
emergence of internal variables or external factors that would alter our view. 
 
There is uncertainty in the estimates of ultimate losses. Significant risk factors to the reserve estimate include, but are not 
limited to, unforeseen or unquantifiable changes in: 
 
 
Loss payment patterns, 
 
 
Loss reporting patterns, 
 
 
Frequency and severity trends, 
 
 
Underlying policy terms and conditions, 
 
 
Business or exposure mix, 
 
 
Operational or internal processes affecting the timing of loss and LAE transactions, 
 
 
Regulatory and legal environment and/or 
 
 
Economic environment. 
 
Our actuaries engage in discussions with senior management, underwriters and the claim department on a regular basis to 
ascertain any substantial changes in operations or other assumptions that are necessary to consider in the reserving analysis. 
 
A considerable degree of judgment in the evaluation of all these factors is involved in the analysis of reserves. The human 
element in the application of judgment is unavoidable when faced with uncertainty. Different experts will choose different 
assumptions based on their individual backgrounds, professional experiences and areas of focus. Hence, the estimates selected by 
various qualified experts may differ significantly from each other. We consider this uncertainty by examining our historic reserve 
accuracy and through an internal and external review process. 
 
Given the substantial impact of the reserve estimates on our financial statements, we subject the reserving process to significant 
diagnostic testing and reasonability checks. In addition, there are data validity checks and balances in our front-end processes. Data 
anomalies are researched and explained to reach a comfort level with the data and results. Leading indicators such as actual versus 
expected emergence and other diagnostics are also incorporated into the reserving processes. 
 
Determination of Our Best Estimate 
 
Our best estimate of ultimate loss and LAE reserves are proposed by our lead reserving actuary and then discussed and approved 
by our Loss Reserve Committee (LRC). The LRC is made up of various members of the management team including the lead 
reserving actuary, chief executive officer, chief operating officer, chief financial officer, chief claim officer, chief legal officer and 
other selected executives. As part of the discussion with the LRC, the analysis supporting the actuarial central estimate of the IBNR 
reserve by product is reviewed. The actuaries also present explanations supporting any changes to the underlying assumptions used to 
calculate the indicated central estimate. Our actuaries make a recommendation to management in regard to booked reserves that reflect 
both their analytical assessment and relevant qualitative factors, such as their view of estimation risk. After discussion of these 
analyses, recommendations and all relevant risk factors among the LRC, our actuaries determine whether the reserve balances require 
further adjustment.  
 
As a predominantly excess and surplus lines and specialty admitted insurer serving niche markets, we believe we are subject to 
above-average variation in estimates and that this variation is not symmetrical around the actuarial central estimate. 
 
One reason for the variation is the above-average policyholder turnover and changes in the underlying mix of exposures typical 
of an excess and surplus lines business. This constant change can cause estimates based on prior experience to be less reliable than 
estimates for more stable, admitted books of business. Also, as a niche market insurer, there is little industry-level information for 

35 
direct comparisons of current and prior experience and other reserving parameters. These unknowns create greater-than-average 
variation in the actuarial central estimates. 
 
Actuarial methods attempt to quantify future outcomes. However, insurance companies are subject to unique exposures that are 
difficult to foresee when coverage is initiated. Judicial and regulatory bodies involved in interpretation of insurance contracts have 
increasingly found opportunities to expand coverage beyond that which was intended or contemplated at the time the policy was 
issued. Many of these policies offer broad coverages (with named exclusion) and are issued on an occurrence basis. Claimants have at 
times sought coverage beyond the insurer’s original intent, including seeking to void or limit exclusionary language. 
 
Because of the variation and the likelihood that there are unforeseen and under-quantified liabilities absent from the actuarial 
estimate, we believe there are circumstances where it is prudent to enhance our normal reserving process. Generally, these are 
circumstances where we have qualitative information and knowledge of increased risk, but those circumstances have not occurred 
within the history of our quantitative data. In these situations, we will rely on that qualitative information, usually from our claim team 
or underwriting staff, and make an enhancement to our normal process. In general, these enhancements will result in an increased 
overall reserve level compared to reserves based only on observed quantitative information. In the cases where these risks fail to 
materialize, favorable loss development will likely occur in subsequent periods. It is also possible that the risks materialize above the 
enhanced reserve level, in which case unfavorable loss development will likely occur in subsequent periods. 
 
Our best estimate of loss and LAE reserves may change as a result of a revision in the actuarial central estimate, the actuary’s 
certainty in the estimates and processes and our overall view of the underlying risks. From time to time, we benchmark our reserving 
policies and procedures and refine them by adopting industry best practices where appropriate. A detailed, ground-up analysis of the 
reserve estimation risks associated with each of our products and segments, including an assessment of industry information, is 
performed annually. This information is used when determining management’s best estimate of booked reserves. 
 
We do not use discounting in reporting our estimated reserves for losses and settlement expenses. 
 
Loss reserve estimates are subject to a high degree of variability due to the inherent uncertainty of ultimate settlement values. 
Periodic adjustments to these estimates will likely occur as the actual loss emergence reveals itself over time. Our loss reserving 
processes reflect accepted actuarial practices and our methodologies result in a reasonable provision for reserves as of December 31, 
2024. 
 
Reserve Sensitivities 
 
There are three major parameters that have significant influence on our actuarial estimates of ultimate liabilities by product. 
They are the actual losses that are reported, the expected loss emergence pattern and the expected loss ratios used in the analyses. If 
the actual losses reported do not emerge as expected, it may cause the Company to challenge all or some of our previous assumptions. 
We may change expected loss emergence patterns, the expected loss ratios used in our analysis and/or the weights we place on a given 
actuarial method. The impact will be much greater and more leveraged for products with longer emergence patterns. Our general 
liability product is an example of a product with a relatively long emergence pattern. The following chart illustrates the sensitivity of 
our general liability reserve estimates to these key parameters. We believe the scenarios to be reasonable, as similar favorable 
variations have occurred in recent years. For example, our general liability calendar year emergence on prior accident years has ranged 
from 17 percent to 27 percent favorable and our transportation emergence has ranged from 30 percent adverse to 40 percent favorable 
over the last three calendar years, while our overall emergence for all products combined has ranged from 13 percent to 25 percent 
favorable. The numbers below are the changes in estimated ultimate loss and ALAE in millions of dollars as of December 31, 2024, 
resulting from the change in the parameters shown. These parameters were applied to a general liability net loss and LAE reserve 
balance, which was $209 million at December 31, 2024.

There are often significant interrelationships between our reserving assumptions that have offsetting or compounding effects on 
the reserve estimate. Thus, in almost all cases, it is impossible to discretely measure the effect of a single assumption or construct a 
meaningful sensitivity expectation that holds true in all cases. The scenario above is representative of general liability, one of our 

36 
largest and longest-tailed products. It is unlikely that all of our products would have variations as wide as illustrated in the example. It 
is also unlikely that all of our products would simultaneously experience favorable or unfavorable loss development in the same 
direction or at their extremes during a calendar year. Because our portfolio is made up of a diversified mix of products, there would 
ordinarily be some offsetting favorable and unfavorable emergence by product as actual losses start to emerge and our loss estimates 
become more reliable. 
 
INVESTMENT VALUATION 
 
Throughout each year, we and our investment managers buy and sell securities to achieve investment objectives in accordance 
with investment policies established and monitored by our board of directors and executive officers. 
 
Equity securities are carried at fair value with unrealized gains and losses recorded within net earnings. We classify our 
investments in fixed income securities into one of three categories: trading, held-to-maturity or available-for-sale. We do not hold any 
securities classified as trading or held-to-maturity. Available-for-sale securities are carried at fair value with unrealized gains and 
losses recorded as a component of comprehensive earnings and shareholders’ equity, net of deferred income taxes. 
 
Fair value is defined as the price in the principal market that would be received for an asset to facilitate an orderly transaction 
between market participants on the measurement date. We determine the fair value of certain financial instruments based on their 
underlying characteristics and relevant transactions in the marketplace. We maximize the use of observable inputs and minimize the 
use of unobservable inputs when measuring fair value. 
 
RECOVERABILITY OF REINSURANCE BALANCES 
 
Ceded unearned premiums and reinsurance balances recoverable on paid and unpaid losses and settlement expenses are reported 
separately as assets, rather than being netted with the related liabilities, since reinsurance does not relieve the Company of its liability 
to policyholders. Such balances are subject to the credit risk associated with the individual reinsurer. We continually monitor the 
financial condition of our reinsurers and actively follow up on any past due or disputed amounts. As part of our monitoring efforts, we 
review their annual financial statements and Securities and Exchange Commission (SEC) filings for reinsurers that are publicly traded. 
We also review insurance industry developments that may impact the financial condition of our reinsurers. We analyze the credit risk 
associated with our reinsurance balances recoverable by monitoring the AM Best and Standard & Poor’s (S&P) ratings of our 
reinsurers. Additionally, we perform an in-depth reinsurer financial condition analysis prior to the renewal of our reinsurance 
placements. 
 
Once regulatory action (such as receivership, finding of insolvency, order of conservation or order of liquidation) is taken 
against a reinsurer, the paid and unpaid balance recoverable from the reinsurer are specifically identified and charged to earnings in 
the form of an allowance for uncollectible amounts. We subject our remaining reinsurance balances receivable to detailed 
recoverability tests, including a segment-based analysis using the average default rating percentage by S&P rating, and record an 
additional allowance for unrecoverable amounts from reinsurers. This credit allowance is reviewed on an ongoing basis to ensure that 
the amount makes a reasonable provision for reinsurance balances that we may be unable to recover. 
 
DEFERRED POLICY ACQUISITION COSTS 
 
We defer incremental direct costs that relate to the successful acquisition of new or renewal insurance contracts, including 
commissions and premium taxes. Acquisition-related costs may be deemed ineligible for deferral when they are based on contingent 
or performance criteria beyond the basic acquisition of the insurance contract, or when efforts to obtain or renew the insurance 
contract are unsuccessful. All eligible costs are capitalized and charged to expense in proportion to premium revenue recognized. The 
method followed in computing deferred policy acquisition costs limits the amount of such deferred costs to their estimated realizable 
value. This process contemplates the premiums to be earned, anticipated losses and settlement expenses and certain other costs 
expected to be incurred, but does not consider investment income. Judgments as to the ultimate recoverability of such deferred costs 
are reviewed on a segment basis and are highly dependent upon estimated future loss costs associated with the premiums written. This 
deferral methodology applies to both gross and ceded premiums and acquisition costs. 
 
DEFERRED TAXES 
 
We record deferred tax assets and liabilities to the extent that temporary differences between the tax basis and GAAP basis of an 
asset or liability result in future taxable or deductible amounts. Our deferred tax assets relate to expected future tax deductions arising 
from claim reserves and future taxable income related to changes in our unearned premium and unrealized losses on our fixed income 

37 
portfolio. We also have a significant amount of deferred tax liabilities from unrealized gains on the equity portfolio and deferred 
acquisition costs. 
 
Periodically, management reviews our deferred tax positions to determine if it is more likely than not that the assets will be 
realized. These reviews include, among other things, the nature and amount of the taxable income and expense items, the expected 
timing of when assets will be used or liabilities will be required to be reported, as well as the reliability of historical profitability of 
businesses expected to provide future earnings. Furthermore, management considers tax planning strategies it can use to increase the 
likelihood that the tax assets will be realized. After conducting the periodic review, if management determines that the realization of 
the tax asset does not meet the more likely than not criteria, an offsetting valuation allowance is recorded, thereby reducing net 
earnings and the deferred tax asset in that period. In addition, management must make estimates of the tax rates expected to apply in 
the periods in which future taxable items are realized. Such estimates include determinations and judgments as to the expected manner 
in which certain temporary differences, including deferred amounts related to our equity method investment, will be recovered. These 
estimates enter into the determination of the applicable tax rates and are subject to change based on the circumstances. 
 
We consider uncertainties in income taxes and recognize those in our financial statements as required. As it relates to 
uncertainties in income taxes, our unrecognized tax benefits, including interest and penalty accruals, are not considered material to the 
consolidated financial statements. Also, no tax uncertainties are expected to result in significant increases or decreases to 
unrecognized tax benefits within the next 12-month period. Penalties and interest related to income tax uncertainties, should they 
occur, would be included in income tax expense in the period in which they are incurred. 
 
Additional discussion of other significant accounting policies may be found in note 1 to the consolidated financial statements 
within Item 8, Financial Statements and Supplementary Data. 
 
RESULTS OF OPERATIONS 
 
This section of this Form 10-K generally discusses 2024 and 2023 items and year-to-year comparisons between 2024 and 2023. 
Discussions of 2022 items and year-to-year comparisons between 2023 and 2022 that are not included in this Form 10-K can be 
found in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations of the Company’s Annual 
Report on Form 10-K for the fiscal year ended December 31, 2023, incorporated herein by reference. 
 
Consolidated revenue for 2024 totaled $1.8 billion, up $258 million from 2023. Net premiums earned for the Group increased 
18 percent, driven primarily by growth from our property and casualty segments. Positive equity market returns during 2024 resulted 
in $82 million of unrealized gains on equity securities, building on a rally that led to $65 million of unrealized gains in our equity 
portfolio during 2023. Net investment income increased by 18 percent in 2024, primarily due to higher reinvestment rates and a larger 
average asset base relative to the prior year.

UNDERWRITING RESULTS 
 
We surpassed $2 billion in gross premiums written for the first time and achieved our 29th consecutive year of underwriting 
profitability in 2024. Our track record of success is built on underwriting discipline and our diversified product portfolio, which allow 
us to navigate various markets. 
 
Gross premiums written increased $206 million, or 11 percent, in 2024 when compared to 2023, with all three segments 
contributing. Despite competitive conditions, a relatively strong economy and positive rate movement benefited much of the insurance 
portfolio. Net premiums earned were up 18 percent in 2024.  
 
Underwriting income was $211 million on an 86.2 combined ratio in 2024, compared to $173 million on an 86.6 combined ratio 
in 2023. Underwriting results for 2024 included $76 million of pretax losses from Hurricanes Beryl, Helene and Milton, as well as $30 
million of other storm losses. Comparatively, 2023 included $49 million of pretax losses and $12 million of reinsurance reinstatement 
premium from the Hawaiian wildfires, as well as $31 million of other storm losses. Results for each period benefited from favorable 
development on prior years’ loss reserves, which provided additional pretax earnings of $95 million in 2024, compared to $109 
million in 2023. Further discussion of reserve development can be found in note 5 to the consolidated financial statements within 
Item 8, Financial Statements and Supplementary Data. 
 
The loss ratio was 48.4 in 2024, compared to 46.7 in 2023. The increase reflects higher net retained catastrophe losses in 2024, 
lower prior period reserve releases and the strengthening of current accident year casualty reserves, primarily on auto exposures. An 
offsetting loss ratio benefit was a modest improvement in the property segment’s current accident year attritional, non-catastrophe loss 
ratio. The expense ratio decreased to 37.8 in 2024, from 39.9 in 2023. Growth of net premiums earned allowed for improved 
leveraging of our expense base, despite continued investments in our people and technology, as well as higher levels of bonus and 
profit-sharing expense that resulted from improved operating performance. 
 
Bonus and profit-sharing amounts earned by executives, managers and associates are predominately influenced by corporate 
performance including operating earnings, combined ratio and return on capital. Favorable loss development and other drivers of 
growth in book value would increase bonus and profit-sharing expenses, while catastrophe losses, adverse loss development and 
negative equity portfolio returns would lead to expense reductions. These performance-related expenses impact policy acquisition, 
insurance operating and general corporate expenses.  
 
A large portion of our reinsurance placements renewed on January 1, 2025. For our property treaties, the risk-adjusted rate 
change was down 10 percent to 20 percent, with greater decreases in the higher layers. Prepaid reinstatements were added back to the 
bottom half of the catastrophe tower, which reduces the net loss impact on catastrophe events. The risk-adjusted rate change for our 
casualty treaties was plus or minus 5 percent, depending on the underlying coverage.  
 
Like most of the industry, we are closely monitoring the severity of auto losses, which adversely impacted our current and prior 
accident year losses in 2024. The goal of our business model has always been to underwrite for profit and our underwriters are 
incentivized to walk away from underpriced risks. We obtained rate increases across most of our insurance portfolio in 2024. 
However, we are not solely reliant on rate to pursue profitable underwriting. We utilize our in-house loss control team to encourage 
our commercial auto insureds to follow safe practices, work with producers to balance growth and exit classes of business or 
individual accounts that are driving loss severity. We have a strong feedback loop between our underwriting, claim and analytical 
teams that address new or prevailing topics, like legal system abuse. Overall, we remain optimistic about the potential underlying 
profitability of our product portfolio. Our investments in technology and specialized underwriting staff should put us in a position to 
take advantage of opportunities as we move forward.

Casualty 
 
Gross premiums written for casualty were up $147 million in 2024. We continued to benefit from positive rate movement across 
a large portion of our casualty segment, as well as from new business growth within our personal umbrella and small commercial 
distribution channels. The commercial excess product grew as new project work resulted in more business opportunities and renewal 
retention improved. Commercial transportation benefited from an increase in new business submissions and new products, including 
moving and storage as well as an excess and surplus lines offering. Our executive products premium decreased, largely due to a 
continued soft management liability marketplace. 
 
The casualty segment remains highly diversified, allowing select products to work through challenges, while the success of 
other products allows us to achieve positive overall results. Rate filings for personal umbrella were approved in the second half of 
2024, and where increases can be justified, we will be pursuing further rate increases for auto-exposed lines. With the broader industry 
experiencing higher loss severity trends, we see potential for ongoing market disruption. As with all our segments, our investments in 
underwriting talent and strong relationships with producers should put us in position to take advantage of market opportunities as they 
arise. However, our underwriters are incentivized and empowered to shrink our top line revenue to protect our bottom-line 
profitability when necessary. 
 
Property 
 
Gross premiums written for the property segment were up $46 million in 2024, with commercial property contributing $15 
million of that growth. Property lines within the excess and surplus market are in transition and conditions began to change mid-year. 
Rates for wind coverages were down in the second half of the year after multiple years of double-digit rate increases. We have started 
to see more competition and the deterioration of terms and conditions, but are willing to forgo opportunities that do not meet our 
underwriting standards. The earthquake market has also been affected by intense competition and some businesses deciding not to 
procure coverage. 
 

40 
We leverage our underwriting expertise by acting as a Lloyd’s coverholder and write coastal wind and earthquake exposures on 
a syndicated policy. While allowing us to diversify risk through a mechanism outside of reinsurance, this approach also allows us to 
generate fee income that offsets underwriting expense. Combined with the challenging property market, an increased percentage of 
premium being written by our syndicated partner resulted in a decline in earthquake and wind exposures for the Company. However, 
our fire and other peril coverage offerings experienced growth, resulting in overall premium expansion for commercial property. All 
coverages remain well priced and we believe there is opportunity to continue writing profitable business in these spaces.  
 
A strong construction market and an expansion of newer offerings led to increased submissions and $21 million of premium 
growth for our marine product. Additionally, some competitors have reduced their appetite for select Hawaii homeowner coverages, 
which, along with rate increases that became effective during the fourth quarter, has allowed our other property premium to grow. 
 
Surety 
 
Gross premiums written for the surety segment were up $14 million in 2024 and we continue to invest in infrastructure to 
support long-term growth. Contract surety benefited from new agency relationships, new construction projects and elevated material 
costs, while transactional surety grew organically by leveraging existing relationships from complementary products. Despite a highly 
competitive commercial surety market, the expansion of existing accounts and new business also allowed for premium growth. 
Industry loss ratios have increased, particularly in the contract surety space. However, our underwriters monitor the financial condition 
of principals and partner with them to support achievable projects, which has helped us avoid material losses in the past. We believe 
this collaborative approach will help us write profitable business going forward.

Casualty 
 
Underwriting income for the casualty segment was $18 million on a 97.9 combined ratio in 2024, compared to $59 million on a 
92.2 combined ratio in 2023. The decline was the result of decreased favorable development on prior accident years’ reserves and an 
increase in current accident year losses, primarily on auto related exposures. 
 
Favorable development on prior accident years’ loss reserves contributed to underwriting earnings in each of the past two years. 
The total benefit from favorable development on prior years’ reserves was $53 million for 2024, which was largely attributable to 
accident years 2019 through 2023. Favorable development was widespread, with notable amounts from commercial excess, general 
liability, executive products, professional services and our mortgage reinsurance program within other casualty. Commercial 
transportation and small commercial experienced adverse prior accident year development, largely related to auto exposures. 
Comparatively, results for the casualty segment in 2023 included favorable development of $78 million, with the majority attributable 
to commercial excess, general liability, personal umbrella, executive products and professional services across accident years 2015 
through 2022. Hurricane and storm losses on casualty-oriented package policies that include property coverage resulted in $5 million 
of losses in 2024, compared to $2 million of storm losses in 2023. 
 
The segment’s loss ratio was 61.5 in 2024, compared to 55.1 in 2023. The higher loss ratio in 2024 was due to lower amounts of 
favorable development on prior years’ reserves and strengthening our current accident year reserves for our personal umbrella, 
transportation and professional services products. The expense ratio for the casualty segment was 36.4 in 2024, compared to 37.1 in 
2023. 
 

41 
Property 
 
Underwriting income from the property segment was $168 million on a 68.5 combined ratio in 2024, compared to $86 million 
on a 78.5 combined ratio in 2023. Underwriting results for 2024 included $33 million of favorable development on prior years’ 
attritional and catastrophe loss reserves, largely from the marine and commercial property businesses; $73 million of losses from 
Hurricanes Beryl, Helene and Milton; as well as $28 million of other storm losses. Results for 2023 included $21 million of favorable 
development on prior years’ loss and catastrophe reserves, primarily from the commercial property business; $49 million of losses and 
$12 million of reinsurance reinstatement premium from Hawaiian wildfires; as well as $29 million of other storm losses. 
 
A larger earned premium base resulted in higher levels of underwriting income as well as a lower expense ratio. The segment’s 
loss ratio was 37.4 in 2024, compared to 42.9 in 2023. Catastrophe losses added 19 points to the loss ratio in 2024, compared to 20 
points of impact in 2023. Additionally, the current accident year attritional loss ratio improved in 2024. The expense ratio for the 
property segment declined to 31.1 in 2024, from 35.6 in 2023, as the growth in the earned premium base exceeded the growth in 
expense. Furthermore, the expense ratio benefited from an increase in fee income, which was the result of producing more premium 
for our syndicated partner. 
 
Surety 
 
Underwriting income for the surety segment totaled $25 million on an 82.2 combined ratio in 2024, compared to $27 million on 
a 79.6 combined ratio in 2023. Underwriting performance for each year reflects a combination of positive current accident year results 
and favorable development in prior accident years’ loss reserves. Favorable development on prior accident years’ reserves decreased 
loss and settlement expenses for the segment by $9 million for 2024 and 2023.  
 
The segment’s loss ratio was 11.2 in 2024, compared to 10.7 in 2023. An increase in the current accident year loss ratio led to 
the slightly higher overall loss ratio for the segment. The expense ratio for the surety segment was 71.0 in 2024, up from 68.9 in 2023, 
due to increases in select policy acquisition costs, as well as continued investments in technology and people to support growth and 
improve the customer experience. 
 
NET INVESTMENT INCOME AND REALIZED INVESTMENT GAINS 
 
During 2024, net investment income increased by 18 percent. The increase was primarily due to higher interest rates and an 
increased asset base relative to the prior year. The average annual yields on our investments were as follows for 2024 and 2023:

The after-tax yield reflects the different tax rates applicable to each category of investment. Our taxable fixed income securities 
were subject to a corporate tax rate of 21 percent, our tax-exempt municipal securities were subject to a tax rate of 5.3 percent and our 
dividend income was generally subject to a tax rate of 13.1 percent. During 2024, the average after-tax yield on the taxable fixed 
income portfolio was 3.0 percent, an increase from 2.8 percent in the prior year. The average after-tax yield on the tax-exempt 
portfolio was 2.7 percent for both 2024 and 2023. 
 
The fixed income portfolio increased by $320 million during the year, as we allocated the majority of available cash flow to 
investment grade bonds and experienced positive market performance throughout the year. The tax-adjusted total return on a mark-to-
market basis was 3.4 percent. Our equity portfolio increased by $146 million to $736 million in 2024 as a result of strong equity 
market returns during the year. The total return for the year on the equity portfolio was 21.1 percent.

In 2024, we recognized $31 million of net realized gains in the equity portfolio, $5 million of net realized losses in the fixed

portfolio, $3 million of net realized losses in the fixed income portfolio and $14 million of other net realized gains, primarily from the 
payout of the working capital escrow associated with our sale of Maui Jim. 
 
Investment income was aided by higher interest rates in 2024, as the Federal Reserve kept the Fed Funds target high relative to 
recent history. Entering 2025, consensus is the Federal Reserve’s current policy will continue balancing price stability against 
maximum employment, and result in two to three rate cuts over the coming year. A stable interest rate environment and a larger 
invested asset base should offer continued investment income growth. However, if yields decline dramatically from current levels, 
investment income growth may be limited. 
 
INVESTMENTS 
 
We maintain a diversified investment portfolio with a prudent mix of fixed income and risk assets. We continually monitor 
economic conditions, our capital position, the insurance market and relative value in the capital markets to determine our tactical 
allocation. As of December 31, 2024, the portfolio had a fair value of $4.1 billion, an increase of $408 million from the end of 2023. 
Excluding U.S. government and agency issues, no single issuer in either the fixed income or equity portfolio represented more than 
1 percent of invested assets. 
 
We determined the fair value of certain financial instruments based on their underlying characteristics and relevant transactions 
in the marketplace. We maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair 
value. For additional information, see notes 1 and 2 to the consolidated financial statements within Item 8, Financial Statements and 
Supplementary Data.

In selecting the maturity of securities in which we invest, we consider the relationship between the duration of our fixed income 
investments and the duration of our liabilities, including the expected ultimate payout patterns of our reserves. We believe that both 
liquidity and interest rate risk can be minimized by such asset/liability management. As of December 31, 2024, our fixed income 
portfolio’s duration was 4.9 years. 
 
Consistent underwriting income allows a portion of our investment portfolio to be invested in equity securities and other risk 
asset classes. Equities comprised 18 percent of our total 2024 portfolio, up from 16 percent at the end of 2023, as equity markets rose 
over the course of the year. Securities within the equity portfolio are well diversified and are primarily invested in broad index 
exchange traded funds (ETFs). Our actively managed equity strategy has a preference for dividend income and value-oriented security 
selection with low turnover, which minimizes transaction costs and taxes throughout our extended investment horizon.

Agency MBS represented 12 percent of the fixed income portfolio, compared to 15 percent as of December 31, 2023. Our 
objective for the agency MBS portfolio is to provide reasonable cash flow stability where we are compensated for the call risk 
associated with residential mortgage refinancing. The agency MBS portfolio includes mortgage-backed pass-through securities and 
collateralized mortgage obligations (CMO), which include planned amortization classes and sequential pay structures. As of 
December 31, 2024, all the securities in our agency MBS portfolio were rated AA and issued by Government Sponsored Enterprises 
(GSEs) such as the Governmental National Mortgage Association, Federal National Mortgage Association or the Federal Home Loan 
Mortgage Corporation. 
 
Variability in the average life of principal repayment is an inherent risk of owning mortgage-related securities. However, we 
reduce our portfolio’s exposure to prepayment risk by seeking characteristics that tighten the probable scenarios for expected cash 

45 
flows. As of December 31, 2024, the agency MBS portfolio contained 68 percent of pure pass-throughs, up from 65 percent as of 
December 31, 2023. An additional 10 percent of the MBS portfolio was invested in sequential payer, down from 13 percent in 2023.

An ABS, CMBS or non-agency residential mortgage-backed security (RMBS) is a securitization collateralized by the cash flows 
from a specific pool of underlying assets. These asset pools can include items such as credit card payments, auto loans, structured 
bank loans in the form of collateralized loan obligations (CLOs) and residential or commercial mortgages. As of December 31, 2024, 
ABS/CMBS/RMBS investments were 13 percent of the fixed income portfolio, compared to 10 percent as of December 31, 2023. 
Fifty-five percent of the securities in the ABS/CMBS/RMBS portfolio were rated AAA as of December 31, 2024, while 85 percent 
were rated A or better. We believe that ABS/CMBS investments often add superior cash flow stability over mortgage pass-throughs or 
CMOs. 
 
When making investments in MBS/ABS/CMBS, we evaluate the quality of the underlying collateral, the structure of the 
transaction, which dictates how any losses in the underlying collateral will be distributed, and prepayment risks. We had $63 million 
in unrealized losses in these asset classes as of December 31, 2024. 
 
Municipal Fixed Income Securities 
 
As of December 31, 2024, municipal bonds comprised 14 percent of our fixed income portfolio, compared to 19 percent as of 
December 31, 2023. We believe municipal fixed income securities can provide diversification and additional tax-advantaged yield to 
our portfolio. Our objective for the municipal fixed income portfolio is to provide reasonable cash flow stability and increased after-
tax yield. 
 
Our municipal fixed income portfolio is comprised of general obligation (GO) and revenue securities. The revenue sources 
include sectors such as sewer and water, public improvement, school, transportation and colleges and universities. As of December 31, 
2024, approximately 50 percent of the municipal fixed income securities in the investment portfolio were GO and the remaining 
50 percent were revenue based. The municipal portfolio is diversified amongst 282 issues. 
 
Ninety-three percent of our municipal fixed income securities were rated AA or better, while 99 percent were rated A or better. 
The municipal portfolio includes 66 percent taxable and 34 percent tax-exempt securities. 
 
Corporate Debt Securities 
 
As of December 31, 2024, our corporate debt portfolio comprised 42 percent of the fixed income portfolio, compared to 43 
percent as of December 31, 2023. The corporate allocation includes floating rate bank loans and bonds that are below investment 
grade in credit quality and offer incremental yield over our core fixed income portfolio. Non-investment grade bonds totaled $148 
million while non-rated Regulation D securities totaled $90 million at the end of 2024. While these Regulation D securities are not 
rated by a traditional nationally recognized statistical rating organization, all but one carry an equivalent investment-grade rating from 

46 
the Securities Valuation Office of the NAIC. The corporate debt portfolio has an overall quality rating of A- diversified among 954 
issues. 
 
The table below illustrates our corporate debt exposure as of December 31, 2024. Private placements include bank loan and 
Regulation D securities.

EQUITY SECURITIES 
 
As of December 31, 2024, our equity portfolio comprised 18 percent of the investment portfolio, up from 16 percent at the end 
of the previous year. The securities within the equity portfolio are well diversified and are primarily invested in broad index ETFs that 
represent market indexes similar to the Russell 3000 Index, Russell 1000 Index and S&P 500 Index. The ETF portfolio is congruent 
with the actively managed equity portfolios and solves for exposures that line up with our overall benchmark index, the Russell 3000. 
In total, the equity portfolio is comprised of 89 securities. 
 
INTEREST AND GENERAL CORPORATE EXPENSE 
 
We incurred $6 million of interest expense on outstanding debt during 2024 and $7 million in 2023. At December 31, 2024, our 
debt included $50 million from our revolving line of credit with PNC Bank, N.A. (PNC). The borrowing may be repaid at any time 
and carries an adjustable interest rate of 5.98 percent as of the end of 2024. Additionally, we borrowed $50 million from the Federal 
Home Loan Bank of Chicago (FHLBC) that matures on November 12, 2025 and pays interest monthly at an annualized rate of 4.44 
percent. Comparatively, at December 31, 2023, our debt consisted of $50 million from our revolving line of credit with PNC and 
carried a floating interest rate of 7.07 percent, as well as $50 million of borrowings from the FHLBC that matured on November 10, 
2024 and paid interest monthly at an annualized rate of 5.44 percent. 
 
We incurred $16 million of general corporate expense during 2024 and 2023. General corporate expenses include director and 
shareholder relation costs and other compensation-related expenses incurred for the benefit of the corporation.  
 
INVESTEE EARNINGS 
 
As of December 31, 2024, we had a 23 percent interest in the equity and earnings of Prime Holdings Insurance Services, Inc. 
(Prime). Prime writes business through two Illinois domiciled insurance carriers, Prime Insurance Company, an excess and surplus 
lines company, and Prime Property and Casualty Insurance Inc., an admitted insurance company. As a private company, the market 
for Prime’s stock is limited. While we have certain rights under our shareholder agreement and maintain a position on Prime’s board 
of directors, we are subject to the decisions of the controlling shareholder, which may impact the value of our investment. In 2024, we 
recorded $5 million in investee losses for Prime, compared to $10 million of investee earnings in 2023. The loss in 2024 is reflective 
of Prime strengthening loss reserves on a number of prior accident years. Additionally, we maintain a quota share reinsurance treaty 
with Prime, which contributed $9 million of gross premiums written and $8 million of net premiums earned during 2024, compared to 
$7 million of gross premiums written and $13 million of net premiums earned during 2023. The decrease in premiums earned is 
attributable to a reduction of our participation in the quota share reinsurance treaty, as well as the competitive market in which Prime 
operates.  
 
We received dividends of $3 million from Prime in 2024, while no dividends were received from Prime in 2023. Dividends 
from our equity method investees have been irregular in nature, and while they provide added liquidity when received, we do not rely 
on those dividends to meet our liquidity needs.  
 

47 
INCOME TAXES 
 
Our effective tax rates were 19.1 percent and 19.3 percent for 2024 and 2023, respectively. Effective rates are dependent upon 
components of pretax earnings, which is impacted by the volatility of unrealized gains and losses in equity securities, and the related 
tax effects. The effective rate was slightly lower in 2024 due to higher levels of tax-favored adjustments, such as excess tax benefits 
on share-based compensation. 
 
Dividends paid to our ESOP result in a tax deduction. Dividends paid to the ESOP in 2024 and 2023 resulted in tax benefits of 
$3 million and $2 million, respectively. These tax benefits reduced the effective tax rate for 2024 and 2023 by 0.6 percent and 
0.4 percent, respectively. 
 
NET UNPAID LOSSES AND SETTLEMENT EXPENSES 
 
The primary liability on our balance sheet relates to unpaid losses and settlement expenses, which represents our estimated 
liability for losses and related settlement expenses before considering offsetting reinsurance balances recoverable. The largest asset on 
our balance sheet, outside of investments, is the reinsurance balances recoverable on unpaid losses and settlement expenses, which 
serves to offset this liability. The liability can be split into two parts: (1) case reserves representing estimates of losses and settlement 
expenses on known claims and (2) IBNR reserves representing estimates of losses and settlement expenses on claims that have 
occurred but have not yet been reported to the Company. Our gross liability for both case and IBNR reserves is reduced by 
reinsurance balances recoverable on unpaid losses and settlement expenses to calculate our net reserve balance. This net reserve 
balance increased to $1.9 billion at December 31, 2024, from $1.7 billion as of December 31, 2023. This reflects net incurred losses of 
$739 million in 2024 offset by paid losses of $490 million, compared to net incurred losses of $604 million offset by $491 million 
paid in 2023. For more information on the changes in loss and LAE reserves by segment, see note 5 to the consolidated financial 
statements within Item 8, Financial Statements and Supplementary Data. 
 
Gross reserves (liability) and the reinsurance balances recoverable (asset) are generally subject to the same influences that affect 
net reserves, though changes to our reinsurance agreements can cause reinsurance balances recoverable to behave differently. Total 
gross loss and LAE reserves increased to $2.7 billion at December 31, 2024, from $2.4 billion at December 31, 2023, while ceded loss 
and LAE reserves decreased to $755 million from $757 million over the same period. 
 
LIQUIDITY AND CAPITAL RESOURCES 
 
OVERVIEW 
 
We have three primary types of cash flows: (1) operating cash flows, which consist mainly of cash generated by our 
underwriting operations and income earned on our investment portfolio, (2) investing cash flows related to the purchase, sale and 
maturity of investments and (3) financing cash flows that impact our capital structure, such as changes in debt, issuance of common 
stock and dividend payments. The following table summarizes these three cash flows over the last two years:

We have posted positive operating cash flow in the last two years. Variations in operating cash flow between periods are largely 
driven by the volume and timing of premium receipt, claim payments, reinsurance and taxes. In addition, fluctuations in insurance 
operating expenses impact operating cash flow. During 2024, the majority of cash outflows were associated with the net purchase of 
fixed income securities, classified as investing activities, and the payment of our regular quarterly dividends and $2.00 per share 
special dividend, classified as financing activities.

We have entered into certain contractual obligations that require the Company to make recurring payments. The following table

Loss and settlement expense reserves represent our best estimate of the ultimate cost of settling reported and unreported claims 
and related expenses. As discussed previously, the estimation of loss and loss expense reserves is based on various complex and 
subjective judgments. Actual losses and settlement expenses paid may deviate, perhaps substantially, from the reserve estimates 
reflected in our financial statements. Similarly, the timing for payment of our estimated losses is not fixed and is not determinable on 
an individual or aggregate basis. The assumptions used in estimating the payments due by periods are based on our historical claims 
payment experience. Due to the uncertainty inherent in the process of estimating the timing of such payments, there is a risk that the 
amounts paid in any period can be significantly different than the amounts disclosed above. Amounts disclosed above are gross of 
anticipated amounts recoverable from reinsurers. Reinsurance balances recoverable on unpaid loss and settlement reserves are 
reported separately as assets, instead of being netted with the related liabilities, since reinsurance does not discharge the Company of 
its liability to policyholders. Reinsurance balances recoverable on unpaid loss and settlement reserves totaled $755 million at 
December 31, 2024, compared to $757 million in 2023. 
 
The next largest contractual obligation relates to debt outstanding. On September 15, 2023, we accessed $50 million from our 
revolving line of credit with PNC Bank, N.A. (PNC). As the borrowing may be repaid at any time and carries an adjustable interest 
rate of 5.98 percent as of the end of 2024, interest on this $50 million borrowing is excluded from the table above. Additionally, on 
November 12, 2024 we borrowed $50 million from the FHLBC. The borrowing matures on November 12, 2025 and monthly interest 
is paid at an annualized rate of 4.44 percent. We are not party to any off-balance sheet arrangements. See note 3 to the consolidated 
financial statements within Item 8, Financial Statements and Supplementary Data for more information on our debt. Additionally, see 
note 2 to the consolidated financial statements within Item 8, Financial Statements and Supplementary Data for information on our 
obligations for other invested assets. 
 
At December 31, 2024, we had cash, short-term investments and other investments maturing within one year of approximately 
$372 million and an additional $739 million of investments maturing between 1 to 5 years. Our revolving line of credit with PNC 
permits us to borrow up to an aggregate principal amount of $100 million, but may be increased up to an aggregate principal amount 
of $130 million under certain conditions. The facility has a three-year term that expires on May 29, 2026. As of December 31, 2024, 
$50 million was outstanding on this facility. Additionally, based on qualifying assets and the $50 million borrowing outstanding with 
the FHLBC as of year-end, additional immediate borrowing capacity from the FHBLC is approximately $15 million. However, under 
certain circumstances, that capacity may be increased based on additional FHLBC stock purchased and available collateral. Our 
membership allows each insurance subsidiary to determine tenor and structure at the time of borrowing.  
 
Our primary objective in managing our capital is to preserve and grow shareholders’ equity and statutory surplus to improve our 
competitive position and allow for expansion of our insurance operations. Our insurance subsidiaries must maintain certain minimum 
capital levels in order to meet the requirements of the states in which we are regulated. Our insurance companies are also evaluated by 
rating agencies that assign financial strength ratings that measure our ability to meet our obligations to policyholders over an extended 
period of time. 
 
We have historically grown our total capital as a result of three sources of funds: (1) earnings on underwriting and investing 
activities, (2) appreciation in the value of our investments and (3) the issuance of common stock and debt. We believe that cash 
generated by operations, cash generated by investments and cash available from financing activities will provide sufficient sources of 
liquidity to meet our anticipated needs over the next 12 to 24 months. We have consistently generated positive operating cash flow. 
The primary factor in our ability to generate positive operating cash flow is underwriting profitability, which we have achieved for 29 
consecutive years.

OPERATING ACTIVITIES 
 
The following list highlights some of the major sources and uses of cash flow from operating activities: 
 
 
 
 
Sources 
  
Uses 
Premiums received 
  
Claims 
Loss payments from reinsurers 
  
Ceded premium to reinsurers 
Investment income (interest and dividends) 
  
Commissions paid 
Funds held 
  
Operating expenses 
 
  
Interest expense 
 
 
Income taxes 
 
  
Funds held 
 
Our largest source of cash is from premiums received from our customers, which we receive at the beginning of the coverage 
period for most policies. Our largest cash outflow is for claims that arise when a policyholder incurs an insured loss. Because the 
payment of claims occurs after the receipt of the premium, often years later, we invest the cash in various investment securities that 
earn interest and dividends. We use cash to pay commissions to brokers and agents, as well as to pay for ongoing operating expenses 
such as salaries, rent, taxes and interest expense. We also utilize reinsurance to manage the risk that we take on our policies. We cede, 
or pay out, part of the premiums we receive to our reinsurers and collect cash back when losses subject to our reinsurance coverage are 
paid. 
 
The timing of our cash flows from operating activities can vary among periods due to the timing by which payments are made or 
received. Some of our payments and receipts, including loss settlements and subsequent reinsurance receipts, can be significant, so 
their timing can influence cash flows from operating activities in any given period. We are subject to the risk of incurring significant 
losses on catastrophes, both natural (such as earthquakes and hurricanes) and man-made (such as terrorism). If we were to incur such 
losses, we would have to make significant claim payments in a relatively concentrated period of time.

We maintain a diversified investment portfolio representing policyholder funds that have not yet been paid out as claims, as well 
as the capital we hold for our shareholders. As of December 31, 2024, our portfolio had a carrying value of $4.1 billion. Portfolio 
assets at December 31, 2024 increased by $408 million, or 11 percent, from December 31, 2023. 
 
Our overall investment philosophy is designed to first protect policyholders by maintaining sufficient funds to meet corporate 
and policyholder obligations and then generate long-term growth in shareholders’ equity. Because our existing and projected liabilities 
are sufficiently funded by the fixed income portfolio, we can improve returns by investing a portion of the surplus (within limits) in a 
risk assets portfolio largely made up of equities. As of December 31, 2024, 48 percent of our shareholders’ equity was invested in 
equities versus 42 percent at year-end 2023. 
 
The fixed income portfolio is structured to meet policyholder obligations and optimize the generation of after-tax investment 
income and total return.

FINANCING ACTIVITIES 
 
In addition to the previously discussed operating and investing activities, we also engage in financing activities to manage our 
capital structure. The following list highlights some of the major sources and uses of cash flow from financing activities: 
 
 
 
 
Sources 
  
Uses 
Proceeds from stock offerings 
  
Shareholder dividends 
Proceeds from debt offerings 
  
Debt repayment 
Shares issued under stock option plans 
  
Share buy-backs 
 
Our capital structure is comprised of equity and debt obligations. As of December 31, 2024, our capital structure consisted of 
$100 million in debt and $1.5 billion of shareholders’ equity. Debt outstanding comprised 6 percent of total capital as of December 31, 
2024. 
 
At the holding company (RLI Corp.) level, we rely largely on dividends from our insurance company subsidiaries to meet our 
obligations for paying principal and interest on outstanding debt, corporate expenses and dividends to RLI Corp. shareholders. As 
discussed further below, dividend payments to RLI Corp. from our principal insurance subsidiary are restricted by state insurance laws 
as to the amount that may be paid without prior approval of the insurance regulatory authorities of Illinois. As a result, we may not be 
able to receive dividends from such subsidiary at times and in amounts necessary to pay desired dividends to RLI Corp. shareholders. 
On a GAAP basis, as of December 31, 2024, our holding company had $1.5 billion in equity. This includes amounts related to the 
equity of our insurance subsidiaries, which is subject to regulatory restrictions under state insurance laws. The unrestricted portion of 
holding company net assets is comprised primarily of investments and cash, including $39 million in liquid investment assets, which 
approximates two-thirds of our normal annual holding company expenditures. Unrestricted funds at the holding company level are 
available to fund debt interest, general corporate obligations and regular dividend payments to our shareholders. If necessary, the 
holding company also has other potential sources of liquidity that could provide for additional funding to meet corporate obligations 
or pay shareholder dividends, which include a revolving line of credit, as well as access to the capital markets. 
 
Ordinary dividends, which may be paid by our principal insurance subsidiary without prior regulatory approval, are subject to 
certain limitations based upon statutory income, surplus and earned surplus. The maximum ordinary dividend distribution from our 
principal insurance subsidiary in a rolling 12-month period is limited by Illinois law to the greater of 10 percent of RLI Ins. 
policyholder surplus, as of December 31 of the preceding year, or the net income of RLI Ins. for the 12-month period ending 
December 31 of the preceding year. Ordinary dividends are further restricted by the requirement that they be paid from earned surplus. 
In 2024 and 2023, RLI Ins. paid ordinary dividends totaling $152 million and $145 million, respectively, to RLI Corp. Any dividend 
distribution in excess of the ordinary dividend limits is deemed extraordinary and requires prior approval from the IDOI. No 
extraordinary dividends were paid in 2024 or 2023. Although RLI Ins. was restricted from distributing ordinary dividends to RLI 
Corp. as of December 31, 2024, the rolling 12-month limitations reset as of January 1st. A total of $241 million in ordinary dividend 
capacity will be available over the course of 2025. In addition to restrictions from our principal subsidiary’s insurance regulator, we 
also consider internal models and how capital adequacy is defined by our rating agencies in determining amounts available for 
distribution. 
 
Our 195th consecutive dividend payment was declared in February 2025 and will be paid on March 20, 2025, in the amount of 
$0.15 per share. Since the inception of cash dividends in 1976, we have increased our annual dividend every year. 
 
PROSPECTIVE ACCOUNTING STANDARDS 
 
Prospective accounting standards are those which we have not implemented because the implementation date has not yet 
occurred. For a discussion of relevant prospective accounting standards, see note 1.D. to the consolidated financial statements within 
Item 8, Financial Statements and Supplementary Data. 
 
Item 7A. Quantitative and Qualitative Disclosures About Market Risk 
 
MARKET RISK DISCLOSURE 
 
Market risk is a general term describing the potential economic loss associated with adverse changes in the fair value of 
financial instruments. Management of market risk is a critical component of our investment decisions and objectives. We manage our 
exposure to market risk by using the following tools: 
 
 
Monitoring the fair value of all financial assets on a constant basis, 

51 
 
 
Changing the character of future investment purchases as needed and 
 
 
Maintaining a balance between existing asset and liability portfolios. 
 
FIXED INCOME AND INTEREST RATE RISK 
 
The most significant short-term influence on our fixed income portfolio is a change in interest rates. Because there is intrinsic 
difficulty predicting the direction and magnitude of interest rate moves, we attempt to minimize the impact of interest rate risk on the 
balance sheet by matching the duration of assets to that of our liabilities. Furthermore, the diversification of sectors and given issuers 
is core to our risk management process, increasing the granularity of individual credit risk. Liquidity and call risk are elements of 
fixed income that we regularly evaluate to ensure we are receiving adequate compensation. Our fixed income portfolio has a 
meaningful impact on financial results and is a key component in our enterprise risk simulations. 
 
Interest rate risk at the time of debt refinancing can also affect our consolidated statement of earnings due to its impact on 
interest expense. We monitor the interest rate environment and evaluate refinancing opportunities as debt maturity dates approach. 
Changes in interest rates do affect the fair value of our debt. However, our debt is reported at amortized cost on the consolidated 
balance sheet and is not adjusted for changes in fair value. 
 
EQUITY PRICE RISK 
 
Equity price risk is the potential that we will incur economic loss due to the decline of common stock prices. Beta analysis is 
used to measure the sensitivity of our equity portfolio to changes in the value of the S&P 500 Index (an index representative of the 
broad equity market). Our current equity portfolio has a beta of 0.9 in comparison to the S&P 500 with a beta of 1.0. This lower beta 
statistic reflects our long-term emphasis on maintaining a value-oriented, dividend-driven investment philosophy for our equity 
portfolio. 
 
SENSITIVITY ANALYSIS 
 
The tables that follow detail information on the market risk exposure for our financial investments as of December 31, 2024. 
Listed on each table is the December 31, 2024 fair value for our assets and the expected pretax reduction in fair value given the stated 
hypothetical events. This sensitivity analysis assumes the composition of our assets remains constant over the period being measured 
and also assumes interest rate changes are reflected uniformly across the yield curve. For example, our ability to hold non-trading 
securities to maturity mitigates price fluctuation risks. For purposes of this disclosure, market risk sensitive instruments are all 
classified as held for non-trading purposes, as we do not hold any trading securities. The examples given are not predictions of future 
market events, but rather illustrations of the effect such events may have on the fair value of our investment portfolio. 
 
As of December 31, 2024, our fixed income portfolio had a fair value of $3.2 billion. The sensitivity analysis uses scenarios of 
interest rates increasing 100 and 200 basis points from their December 31, 2024, levels with all other variables held constant. Such 
scenarios would result in modeled decreases in the fair value of the fixed income portfolio of $158 million and $303 million, 
respectively. Comparatively, our fixed income portfolio had a fair value of $2.9 billion as of December 31, 2023 and scenarios of 
interest rates increasing 100 and 200 basis points would have resulted in modeled decreases of $132 million and $255 million, 
respectively. 
 
As of December 31, 2024, our equity portfolio had a fair value of $736 million. The base sensitivity analysis uses market 
scenarios of the S&P 500 Index declining both 10 percent and 20 percent. These scenarios would result in approximate decreases in 
the equity fair value of $69 million and $137 million, respectively. Comparatively, our equity portfolio had a fair value of $590 
million as of December 31, 2023 and scenarios of the S&P 500 Index declining by 10 percent and 20 percent would have resulted in 
approximate decreases of $55 million and $110 million, respectively. 
 
While the declines in market value outlined below are modeled as instantaneous changes, we would expect movements in 
capital markets to occur over time, with investment income offering an offset to any decrease in prices. 
 
Under the assumptions of rising interest rates and a decreasing S&P 500 Index, the fair value of our assets will decrease from 
their present levels by the indicated amounts.

Notes to Consolidated Financial Statements 
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 
 
A. DESCRIPTION OF BUSINESS 
 
RLI Corp. is an insurance holding company. References to “the Company,” “we,” “our,” “us” or like terms refer to the business 
of RLI Corp. and its subsidiaries. We underwrite select property, casualty and surety products through major subsidiaries collectively 
known as RLI Insurance Group. We conduct operations principally through three insurance companies. RLI Insurance Company (RLI 
Ins.), a subsidiary of RLI Corp. and our principal insurance subsidiary, writes multiple lines of insurance on an admitted basis in all 50 
states, the District of Columbia, Puerto Rico, the Virgin Islands and Guam. Mt. Hawley Insurance Company (Mt. Hawley), a 
subsidiary of RLI Ins., writes excess and surplus lines insurance on a non-admitted basis in all 50 states, the District of Columbia, 
Puerto Rico, the Virgin Islands and Guam. Contractors Bonding and Insurance Company (CBIC), a subsidiary of RLI Ins., writes 
multiple lines of insurance on an admitted basis in all 50 states and the District of Columbia. 
 
B. PRINCIPLES OF CONSOLIDATION AND BASIS OF PRESENTATION 
 
The accompanying consolidated financial statements were prepared in conformity with generally accepted accounting principles 
in the United States of America (GAAP), which differ in some respects from those followed in reports to insurance regulatory 
authorities. The consolidated financial statements include the accounts of our holding company and our subsidiaries. Intercompany 
balances and transactions have been eliminated. 
 
On January 15, 2025, RLI Corp. effected a two-for-one split of its common stock and a proportionate increase in the number of 
authorized shares. All share and per share information throughout this report has been retroactively adjusted to reflect the stock split. 
The shares of common stock retain a par value of $0.01 per share. Accordingly, an amount equal to the par value of the increased 
shares resulting from the stock split was reclassified from paid-in capital to common stock. 
 
The Company has evaluated subsequent events through the date these consolidated financial statements were issued. There were 
no other subsequent events requiring adjustment to the financial statements or disclosure. 
 
C. ADOPTED ACCOUNTING STANDARDS 
 
2023-07—Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures 
 
The amendments in this Accounting Standards Update (ASU) require the disclosures of significant expenses that are regularly 
provided to the chief operating decision maker (CODM) and included within each segment’s reported measure of profit or loss. 
Additionally, the ASU requires the disclosure of the title of the CODM and an explanation of how the CODM uses the reported 
measure of a segment’s profit or loss in assessing performance and deciding how to allocate resources. We adopted ASU 2023-07 in 
2024 using a retrospective approach, providing disclosures for all periods presented in the financial statements. The adoption of this 
ASU did not have a material impact on our consolidated financial statements. 
 
D. PROSPECTIVE ACCOUNTING STANDARDS 
 
2023-09—Income Taxes (Topic 740): Improvements to Income Tax Disclosures 
 
The guidance in ASU 2023-09 is designed to increase transparency about income tax information through improvements to the 
tax rate reconciliation and disclosure of income taxes paid, disaggregated by federal, state and foreign jurisdictions. This ASU is 
effective for fiscal years beginning after December 15, 2024. Although the Company continues to evaluate the impact of adopting this 
new accounting standard, the amendments are disclosure-related and should not have a material impact on our financial statements. 
 
2024-03—Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): 
Disaggregation of Income Statement Expenses 
 
The guidance in ASU 2024-03 requires disaggregation of certain expenses into specified categories in the notes to the financial 
statements. Each relevant expense caption on the face of the statement of earnings that includes specific expenses, such as employee 
compensation, depreciation and intangible asset amortization, are required to be separately disclosed in a tabular presentation. 
Additionally, a separate total of selling expenses is required to be disclosed, along with a definition of what is included in selling 
expenses. 

59 
 
This ASU is effective for fiscal years beginning after December 15, 2026 and interim periods beginning after December 15, 
2027. Although the Company continues to evaluate the impact of adopting this new accounting standard, the amendments are 
disclosure-related and should not have a material impact on our financial statements. 
 
E. INVESTMENTS 
 
Equity securities are carried at fair value with unrealized gains and losses recorded within net earnings. Investments in fixed 
income securities are classified into one of three categories: trading, held-to-maturity or available-for-sale. All of our fixed income 
securities are classified as available-for-sale and reported at fair value. Unrealized gains and losses on these securities are excluded 
from net earnings but are recorded as a separate component of comprehensive earnings and shareholders’ equity, net of deferred 
income taxes. 
 
Interest on fixed maturities and short-term investments is credited to earnings on an accrual basis. Premiums and discounts are 
amortized or accreted over the lives of the related fixed maturities. Dividends on equity securities are credited to earnings on the ex-
dividend date. Realized gains and losses on disposition of investments are based on the specific identification of the investments sold 
on the settlement date. 
 
F. CASH, SHORT-TERM INVESTMENTS AND OTHER INVESTED ASSETS 
 
Cash consists of uninvested balances in bank accounts. Short-term investments consist of investments with original maturities of 
90 days or less, primarily AAA-rated government money market funds. Short-term investments are carried at cost. Other invested 
assets include investments in low-income housing tax credit (LIHTC) and historic tax credit (HTC) partnerships, membership in the 
Federal Home Loan Bank of Chicago (FHLBC) and investments in private funds. Our LIHTC and HTC investments are carried at 
amortized cost, and our investment in FHLBC stock is carried at cost. Due to the nature of cash, the LIHTC and HTC partnerships, 
and our membership in the FHLBC, their carrying amounts approximate fair value. The private funds are carried at fair value, using 
each investment’s net asset value. 
 
G. REINSURANCE 
 
Ceded unearned premiums and reinsurance balances recoverable on unpaid losses and settlement expenses are reported 
separately as an asset, rather than being netted with the related liability, since reinsurance does not relieve the Company of our liability 
to policyholders. Such balances are subject to the credit risk associated with the individual reinsurer. We continually monitor the 
financial condition of our reinsurers and actively follow up on any past due or disputed amounts. As part of our monitoring efforts, we 
review reinsurers’ annual financial statements and SEC filings for those that are publicly traded. We also review insurance industry 
developments that may impact the financial condition of our reinsurers. We analyze the credit risk associated with our reinsurance 
balances recoverable by monitoring the AM Best and S&P ratings of our reinsurers. In addition, we subject our reinsurance balances 
recoverable to detailed recoverability tests, including a segment-based analysis using the average default rating percentage by S&P 
rating, which assists the Company in assessing the sufficiency of its allowance. Additionally, we perform an in-depth reinsurer 
financial condition analysis prior to the renewal of our reinsurance placements. 
 
Our policy is to charge to earnings, in the form of an allowance, an estimate of unrecoverable amounts from reinsurers. This 
allowance is reviewed on an ongoing basis to ensure that the amount makes a reasonable provision for reinsurance balances that we 
may be unable to recover. Once regulatory action (such as receivership, finding of insolvency, order of conservation or order of 
liquidation) is taken against a reinsurer, the paid and unpaid recoverable for the reinsurer are specifically identified and written off 
through the use of our allowance for estimated unrecoverable amounts from reinsurers. When we write-off such a balance, it is done in 
full. We then re-evaluate the remaining allowance and determine whether the balance is sufficient and, if needed, an additional 
allowance is recognized. 
 
H. POLICY ACQUISITION COSTS 
 
We defer incremental direct costs that relate to the successful acquisition of new or renewal insurance contracts, including 
commissions and premium taxes. Acquisition-related costs may be deemed ineligible for deferral when they are based on contingent 
or performance criteria beyond the basic acquisition of the insurance contract or when efforts to obtain or renew the insurance contract 
are unsuccessful. All eligible costs are capitalized and charged to expense in proportion to premium revenue recognized. The method 
followed in computing deferred policy acquisition costs limits the amount of such deferred costs to their estimated realizable value. 
This process contemplates the premiums to be earned, anticipated losses and settlement expenses and certain other costs expected to 
be incurred, but does not consider investment income. Judgments as to the ultimate recoverability of such deferred costs are reviewed 

60 
on a segment basis and are highly dependent upon estimated future loss costs associated with the premiums written. This deferral 
methodology applies to both gross and ceded premiums and acquisition costs. 
 
I. 
PROPERTY AND EQUIPMENT 
 
Property and equipment are presented at cost less accumulated depreciation and are depreciated on a straight-line basis over 
periods ranging from 3 to 10 years for equipment and up to 30 years for buildings and improvements. 
 
J. 
INVESTMENTS IN UNCONSOLIDATED INVESTEES 
 
Our investment in Prime Holdings Insurance Services, Inc. (Prime) is accounted for under the equity method. As of 
December 31, 2024, we had a 23 percent interest in the equity and earnings of Prime. Prime writes business through two Illinois 
domiciled insurance carriers, Prime Insurance Company, an excess and surplus lines company, and Prime Property and Casualty 
Insurance Inc., an admitted insurance company. Our investment in Prime was $56 million at December 31, 2024 and 2023. In 2024, 
we recorded $5 million in investee losses from Prime, compared to investee earnings of $10 million in 2023 and $13 million in 2022. 
The loss in 2024 is reflective of Prime strengthening reserves on a number of prior accident years. Additionally, we maintain a quota 
share reinsurance treaty with Prime, which contributed $9 million of gross premiums written and $8 million of net premiums earned 
during 2024, compared to $7 million of gross premiums written and $13 million of net premiums earned during 2023, and $21 million 
of gross premiums written and $23 million of net premiums earned during 2022. The decrease in gross premiums written and net 
premiums earned from 2022 was attributable to a reduction of our participation in the quota share reinsurance treaty in 2023, as well 
as the competitive market in which Prime operates. 
 
Prime recorded a net loss of $36 million in 2024, compared to net income of $45 million in 2023 and $59 million in 2022. 
Additional summarized financial information for Prime as of 2024 and 2023 is outlined in the following table:

Approximately $54 million of undistributed earnings from our equity method investees were included in our retained earnings 
as of December 31, 2024. We received $3 million of dividends from Prime in 2024. We did not receive any dividends from our equity 
method investees during 2023 or 2022. 
 
We perform annual impairment reviews of our investments in unconsolidated investees, which take into consideration current 
valuation and operating results. Based upon the most recent reviews, the assets were not impaired. 
 
K. GOODWILL AND INTANGIBLE ASSETS 
 
The composition of goodwill and intangibles at December 31, 2024 and 2023, is detailed in the following table:

Total goodwill and intangibles 
 
$

$

As the amortization of goodwill and indefinite-lived intangible assets is not permitted, the assets are tested for impairment on an 
annual basis, or earlier if there is reason to suspect that their values may have been diminished or impaired. Annual impairment testing 
was performed on each of our goodwill and indefinite-lived intangible assets during 2024. Based upon these reviews, our goodwill 
and state insurance license indefinite-lived intangible assets were not impaired. In addition, as of December 31, 2024, there were no 
triggering events on goodwill and intangible assets that would suggest an updated review was necessary. 
 

61 
L. UNPAID LOSSES AND SETTLEMENT EXPENSES 
 
The liability for unpaid losses and settlement expenses represents estimates of amounts needed to pay reported and unreported 
claims and related expenses. The estimates are based on certain actuarial and other assumptions related to the ultimate cost to settle 
such claims. Such assumptions are subject to occasional changes due to evolving economic, social and political conditions. All 
estimates are periodically reviewed and, as experience develops and new information becomes known, the reserves are adjusted as 
necessary. Such adjustments are reflected in the results of operations in the period in which they are determined. Due to the inherent 
uncertainty in estimating reserves for losses and settlement expenses, there can be no assurance that the ultimate liability will not 
exceed recorded amounts. If actual liabilities do exceed recorded amounts, there will be an adverse effect. Furthermore, we may 
determine that recorded reserves are more than adequate to cover expected losses, which would lead to a reduction in our reserves. 
 
M. INSURANCE REVENUE RECOGNITION 
 
Insurance premiums are recognized ratably over the term of the contracts, net of ceded reinsurance. Our policies are short-term 
in nature and premium is generally earned over a one-year period. Unearned premiums are calculated on a monthly pro rata basis. 
 
N. INCOME TAXES 
 
We file a consolidated federal income tax return. Federal income taxes are accounted for using the asset and liability method 
under which deferred income taxes are recognized for the tax consequences of temporary differences by applying enacted statutory tax 
rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of existing assets and 
liabilities, operating losses and tax credit carry forwards. The effect on deferred taxes for a change in tax rates is recognized in income 
in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance if it is more likely than not 
that all or some of the deferred tax assets will not be realized. 
 
We consider uncertainties in income taxes and recognize those in our financial statements as required. As it relates to 
uncertainties in income taxes, our unrecognized tax benefits, including interest and penalty accruals, are not considered material to the 
consolidated financial statements. Also, no tax uncertainties are expected to result in significant increases or decreases to 
unrecognized tax benefits within the next 12-month period. Penalties and interest related to income tax uncertainties, should they 
occur, would be included in income tax expense in the period in which they are incurred. 
 
As an insurance company, we are subject to minimal state income tax liabilities. Since the majority of our income on a state 
basis is from insurance operations, we pay premium taxes, which are calculated as a percentage of gross premiums written in lieu of 
state income taxes. Premium taxes are a component of policy acquisition costs. 
 

62 
O. EARNINGS PER SHARE 
 
Basic earnings per share (EPS) is computed by dividing income available to common shareholders by the weighted-average 
number of common shares outstanding for the period. Diluted EPS reflects the dilution that could occur if securities or other contracts 
to issue common stock or common stock equivalents were exercised or converted into common stock. When inclusion of these items 
increases the earnings per share or reduces the loss per share, the effect on earnings is anti-dilutive. Under these circumstances, the 
diluted net earnings or net loss per share is computed excluding these items. The following represents a reconciliation of the 
numerator and denominator of the basic and diluted EPS computations contained in the consolidated financial statements:

P. COMPREHENSIVE EARNINGS 
 
Our comprehensive earnings include net earnings plus after-tax unrealized gains and losses on our available-for-sale fixed 
income portfolio. In reporting the components of comprehensive earnings, we used the federal statutory tax rate of 21 percent. Other 
comprehensive income (loss), as shown in the consolidated statements of earnings and comprehensive earnings, is net of tax expense 
(benefit) of $(2) million, $17 million and $(74) million for 2024, 2023 and 2022, respectively. 
 
The table below illustrates the changes in the balance of each component of accumulated other comprehensive earnings for each 
period presented in the consolidated financial statements.

Q. FAIR VALUE DISCLOSURES 
 
Fair value is defined as the price in the principal market that would be received for an asset to facilitate an orderly transaction 
between market participants on the measurement date. We determined the fair value of certain financial instruments based on their 
underlying characteristics and relevant transactions in the marketplace. We maximize the use of observable inputs and minimize the 
use of unobservable inputs when measuring fair value. 
 
The following are the levels of the fair value hierarchy and a brief description of the type of valuation inputs that are used to 
establish each level. Financial assets are classified based upon the lowest level of significant input that is used to determine fair value. 
 
Level 1 is applied to valuations based on readily available, unadjusted quoted prices in active markets for identical assets. 
 
Level 2 is applied to valuations based upon quoted prices for similar assets in active markets, quoted prices for identical or 
similar assets in inactive markets; or valuations based on models where the significant inputs are observable (e.g. interest 
rates, yield curves, prepayment speeds, default rates, loss severities) or can be corroborated by observable market data. 
 
Level 3 is applied to valuations that are derived from techniques in which one or more of the significant inputs are 
unobservable. 
 
As a part of management’s process to determine fair value, we utilize widely recognized, third-party pricing sources to 
determine our fair values. We have obtained an understanding of the third-party pricing sources’ valuation methodologies and inputs. 
The following is a description of the valuation techniques used for financial assets that are measured at fair value, including the 
general classification of such assets pursuant to the fair value hierarchy. 
 
Corporate, Agencies, Government and Municipal Bonds: The pricing vendor employs a multi-dimensional model which 
uses standard inputs including (listed in approximate order of priority for use) benchmark yields, reported trades, broker/dealer quotes, 
issuer spreads, two-sided markets, benchmark securities, market bids/offers and other reference data. The pricing vendor also monitors 
market indicators, as well as industry and economic events. All bonds valued using these techniques are classified as Level 2. All 
Corporate, Agencies, Government and Municipal securities are deemed Level 2. 
 
Mortgage-backed Securities (MBS)/Collateralized Mortgage-backed Securities (CMBS) and Asset-backed Securities 
(ABS): The pricing vendor evaluation methodology includes principally interest rate movements and new issue data. Evaluation of the 
tranches (nonvolatile, volatile or credit sensitivity) is based on the pricing vendors’ interpretation of accepted modeling and pricing 
conventions. This information is then used to determine the cash flows for each tranche, benchmark yields, pre-payment assumptions 
and to incorporate collateral performance. To evaluate MBS and CMBS volatility, an option adjusted spread model is used in 
combination with models that simulate interest rate paths to determine market price information. This process allows the pricing 
vendor to obtain evaluations of a broad universe of securities in a way that reflects changes in yield curve, index rates, implied 
volatility, mortgage rates and recent trade activity. MBS/CMBS and ABS with corroborated, observable inputs are classified as Level 
2. All of our MBS/CMBS and ABS are deemed Level 2. 
 
Regulation D Private Placement Securities: All Regulation D privately placed bonds are classified as corporate or non-U.S. 
government securities and deemed Level 3. The pricing vendor evaluation methodology for these securities includes a combination of 

64 
observable and unobservable inputs. Observable inputs include public corporate spread matrices classified by sector, rating and 
average life, as well as investment and non-investment grade matrices created from fixed income indices. Unobservable inputs include 
a liquidity spread premium calculated based on public corporate spread and private corporate spread matrices. The quantitative detail 
of the liquidity spread premium is neither provided nor reasonably available to the Company. 
 
For all of our fixed income securities classified as Level 2, we periodically conduct a review to assess the reasonableness of the 
fair values provided by our pricing services. Our review consists of a two-pronged approach. First, we compare prices provided by our 
pricing services to those provided by an additional source. In some cases, we obtain prices from securities brokers and compare them 
to the prices provided by our pricing services. If discrepancies are found in our comparisons, we compare our prices to actual reported 
trade data for like securities. No changes to the fair values supplied by our pricing services have occurred as a result of our reviews. 
Based on these assessments, we have determined that the fair values of our Level 2 fixed income securities provided by our pricing 
services are reasonable. 
 
Equity Securities: As of December 31, 2024, nearly all of our equity holdings were traded on an exchange. Exchange traded 
equities have readily observable price levels and are classified as Level 1 (fair value based on quoted market prices). Equity securities 
not traded on an exchange, for which pricing is provided by a third-party pricing source using observable inputs, are classified as 
Level 2. Equity securities not traded on an exchange and that rely on one or more unobservable inputs in pricing are classified as 
Level 3. 
 
Due to the relatively short-term nature of cash, short-term investments, accounts receivable and accounts payable, their carrying 
amounts are reasonable estimates of fair value. Our investments in private funds, classified as other invested assets, are measured 
using the investments’ net asset value per share and are not categorized within the fair value hierarchy. The fair value of our debt is 
discussed further in note 3 to the consolidated financial statements. 
 
R. SHARE-BASED COMPENSATION 
 
We expense the estimated fair value of employee stock options and similar awards. We measure compensation cost for awards 
of equity instruments to employees based on the grant-date fair value of those awards and recognize compensation expense over the 
service period that the awards are expected to vest. The tax effects related to share-based payments are made through net earnings. See 
note 7 to the consolidated financial statements for further discussion and related disclosures regarding stock options. 
 
S. RISKS AND UNCERTAINTIES 
 
Certain risks and uncertainties are inherent in our day-to-day operations and in the process of preparing our consolidated 
financial statements. The more significant risks and uncertainties, as well as our attempt to mitigate, quantify and minimize such risks, 
are presented below and throughout the notes to the consolidated financial statements. 
 
Insurance Risks 
 
We compete with a large number of other companies in our selected lines of business. During periods of intense competition for 
premium, we are vulnerable to the actions of other companies who may seek to write business without the appropriate regard for risk 
and profitability. The insurance industry is often highly competitive, which can make it difficult to grow or maintain premium volume 
without sacrificing underwriting discipline and income. Our profitability can be significantly affected by the ability of our 
underwriters to accurately select and price risk and our claim personnel to appropriately deliver fair outcomes. We attempt to mitigate 
this risk by incentivizing our underwriters to maximize underwriting profit and remain disciplined in pricing and selecting risks. If we 
are unable to compete effectively in the markets in which we operate or expand our operations into new markets, our underwriting 
revenues may decline, as well as overall business results. 
 
Our loss reserves are based on estimates and may be inadequate to cover our actual insured losses, which would negatively 
impact our profitability. As of December 31, 2024, we had $2.7 billion of gross loss and LAE reserves. Significant periods of time 
often elapse between the occurrence of an insured loss, the reporting of the loss to the Company and our payment of that loss. As part 
of the reserving process, we review historical data and consider the impact of various factors such as trends in claim frequency and 
severity, emerging economic and social trends, inflation and changes in the regulatory and litigation environments. If the actual 
amount of insured losses is greater than the amount we have reserved for these losses, our profitability would suffer. 
 

65 
Catastrophe Exposures 
 
Our insurance coverages include exposure to catastrophic events. We monitor catastrophe exposures by quantifying our exposed 
policy limits in each region and by using computer-assisted modeling techniques. Additionally, we limit our risk to such catastrophes 
by restraining the total policy limits written in each region and by purchasing reinsurance. Our major catastrophe exposure is to losses 
caused by windstorms, affecting commercial properties in coastal regions of the United States, and earthquakes, primarily on the West 
Coast. We are also exposed to convective storms, winter weather, wildfires, lava flows in Hawaii as well as terrorist events in the 
United States. 
 
In 2024, our property catastrophe reinsurance treaty had limits of $850 million in excess of $25 million first-dollar retention for 
earthquakes in California, $850 million in excess of a $50 million first-dollar retention for earthquakes outside of California and $750 
million in excess of a $50 million first-dollar retention for all other perils, including wind. In addition, we have coverages that may 
reduce first-dollar retentions for multiple events within an established period of time. All of these amounts were subject to certain co-
participations by the Company on losses in excess of the first-dollar retentions.  
 
The majority of our catastrophe reinsurance treaty renewed on January 1, 2025. We purchased the same limits over the same 
first-dollar retention amounts outlined above. The program was 100 percent placed with a portion of the first layer expiring on May 
31, 2025. We actively manage our catastrophe program to keep our net retention in line with risk tolerances and to optimize the 
risk/return trade off. 
 
Environmental Liability Exposures 
 
We are subject to environmental liability claims and exposures primarily through our commercial excess, general liability and 
discontinued assumed casualty reinsurance lines of business. Although exposure to environmental claims exists in these lines of 
business, we seek to mitigate or control the extent of this exposure on the vast majority of this business. Our policies include pollution 
exclusions that have been continually updated to further strengthen them and our policies primarily cover moderate hazard risks. 
 
We offer coverage for low to moderate environmental liability exposures for small contractors and asbestos and mold 
remediation specialists. We also provide limited coverage for individually underwritten underground storage tanks. The overall 
exposure is mitigated by focusing on smaller risks with low to moderate exposures. Risks that have large-scale exposures are avoided 
including petrochemical, chemical, mining, manufacturers and other risks that might be exposed to superfund sites. This business is 
covered under our casualty ceded reinsurance treaties. 
 
We made loss and settlement expense payments on environmental liability claims and have loss and settlement expense reserves 
for others. We include this historical environmental loss experience with the remaining loss experience in the applicable line of 
business to project ultimate incurred losses and settlement expenses as well as related incurred but not reported (IBNR) loss and 
settlement expense reserves. 
 
Although historical experience on environmental liability claims may not accurately reflect future environmental exposures, we 
used this experience to record loss and settlement expense reserves in the exposed lines of business. See further discussion of 
environmental exposures in note 5 to the consolidated financial statements. 
 
Reinsurance 
 
Reinsurance does not discharge the Company from our primary liability to policyholders, and to the extent that a reinsurer is 
unable to meet its obligations, we would be liable. We continuously monitor the financial condition of prospective and existing 
reinsurers. As a result, we purchase reinsurance from a number of financially strong reinsurers. We provide an allowance for 
reinsurance balances deemed uncollectible. See further discussion of reinsurance exposures in note 4 to the consolidated financial 
statements. 
 
Investment Risk 
 
Our investment portfolio is subject to market, credit and interest rate risks. The equity portfolio will fluctuate with movements 
in the overall stock market. While the equity portfolio has been constructed to have lower downside risk than the market, the portfolio 
is positively correlated with movements in domestic stocks. The bond portfolio is affected by interest rate changes and movement in 
credit spreads. We attempt to mitigate our interest rate and credit risks by constructing a well-diversified portfolio with high-quality 
securities with varied maturities. Downturns in the financial markets could have a negative effect on our portfolio. However, we 
attempt to manage this risk through asset allocation, duration and security selection. 

66 
 
Liquidity Risk 
 
Liquidity is essential to our business and a key component of our concept of asset-liability matching. Our liquidity may be 
impaired by an inability to collect premium receivable or reinsurance balances recoverable in a timely manner, an inability to sell 
assets or redeem our investments, an inability to access funds from our insurance subsidiaries, unforeseen outflows of cash or large 
claim payments or an inability to access debt or equity capital markets. This situation may arise due to circumstances that we may be 
unable to control, such as a general market disruption, an operational problem that affects third parties or the Company, or even by the 
perception among market participants that we, or other market participants, are experiencing greater liquidity risk. 
 
Our credit ratings are important to our liquidity. A reduction in our credit ratings could adversely affect our liquidity and 
competitive position by increasing our borrowing costs or limiting our access to the capital markets. 
 
Financial Statements 
 
The preparation of the accompanying consolidated financial statements in conformity with GAAP requires management to make 
estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and 
liabilities reported, disclosures about contingent assets and liabilities and reported amounts of revenues and expenses. The most 
significant of these amounts is the liability for unpaid losses and settlement expenses. Other estimates include investment valuation, 
the allowance for credit losses on fixed income securities, the collectability of reinsurance balances, recoverability of deferred tax 
assets and deferred policy acquisition costs. These estimates and assumptions are based on management’s best estimates and 
judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, 
including the current economic environment, which management believes to be reasonable under the circumstances. We adjust such 
estimates and assumptions when facts and circumstances dictate. Although recorded estimates are supported by actuarial computations 
and other supportive data, the estimates are ultimately based on our expectations of future events. As future events and their effects 
cannot be determined with precision, actual results could differ significantly from these estimates. Changes in those estimates 
resulting from continuing changes in the economic environment will be reflected in the consolidated financial statements in future 
periods. 
 
External Factors 
 
Our insurance subsidiaries are highly regulated by the state in which they are incorporated and by the states in which they do 
business. Such regulations, among other things, limit the amount of dividends, impose restrictions on the amount and types of 
investments, impose regulations on forms and regulate rates insurers may charge for various coverages. We are also subject to 
insolvency and guaranty fund assessments for various programs designed to ensure policyholder indemnification. We generally accrue 
an assessment during the period in which it becomes probable that a liability has been incurred from an insolvency and the amount of 
the related assessment can be reasonably estimated. 
 
The National Association of Insurance Commissioners (NAIC) has developed Property and Casualty Risk-Based Capital (RBC) 
standards that relate an insurer’s reported statutory surplus to the risks inherent in its overall operations. The RBC formula uses the 
statutory annual statement to calculate the minimum indicated capital level to support investment and underwriting risk. The NAIC 
model law calls for various levels of regulatory action based on the magnitude of an indicated RBC capital deficiency, if any. We 
regularly monitor our subsidiaries’ internal capital requirements and the NAIC’s RBC developments. As of December 31, 2024, we 
determined that our capital levels are well in excess of the minimum capital requirements for all RBC action levels and that our capital 
levels are sufficient to support the level of risk inherent in our operations. See note 8 to the consolidated financial statements for 
further discussion of statutory information and related insurance regulatory restrictions. 
 
In addition, ratings are a critical factor in establishing the competitive position of insurance companies. Our insurance 
companies are rated by AM Best, S&P and Moody’s. Their ratings reflect their opinions of an insurance company’s and an insurance 
holding company’s financial strength, operating performance, strategic position and ability to meet its obligations to policyholders.  
 
2. INVESTMENTS 
 
Our investments are primarily composed of fixed income debt securities and common stock equity securities. All of our debt 
securities are classified as available-for-sale, which are carried at fair value. Our equity portfolio consists of common stocks and 
exchange traded funds (ETF), which are carried at fair value.

ALLOWANCE FOR CREDIT LOSSES AND UNREALIZED LOSSES ON FIXED INCOME SECURITIES 
 
A reversible allowance for credit losses is required to be recognized on available-for-sale fixed income securities. Available-for-
sale securities in the fixed income portfolio are subjected to several criteria to determine if those securities should be included in the 
allowance for expected credit loss evaluation, including: 
 
 
Significant or recurring operating losses, poor cash flows and/or deteriorating liquidity ratios, 
 
 
Changes in technology that may impair the earnings potential of the investment, 
 
 
The discontinuance of a segment of business that may affect future earnings potential, 
 
 
Specific concerns related to the issuer’s industry or geographic area of operation, 
 
 
Reduction of or non-payment of interest and/or principal and 
 
 
Downgrades in credit quality by a major rating agency. 
 
If changes in interest rates and credit spreads do not reasonably explain the unrealized loss for an available-for-sale security, or 
if any of the criteria above indicate a potential credit loss, the security is subjected to a discounted cash flow analysis. Inputs into the 
discounted cash flow analysis include prepayment assumptions for structured securities, default rates and recoverability rates based on 
credit rating. The allowance for any security is limited to the amount that the fair value is below amortized cost. As of December 31, 
2024, the discounted cash flow analysis resulted in an allowance for credit losses on eight securities. The following table presents 
changes in the allowance for expected credit losses on available-for-sale securities:

Net realized gains included less than $1 million of losses on fixed income securities for which the cost basis was written down 
to fair value due to a credit event, restructurings and losses on securities for which we no longer had the intent to hold until recovery. 
In 2023, $2 million in such losses were recognized. We believe we will recover the amortized cost basis of available-for-sale securities 
that remain in an unrealized loss position. 
 
As of December 31, 2024, in addition to the securities included in the allowance for credit losses, the fixed income portfolio 
contained 1,333 securities with an unrealized loss position for which an allowance for credit losses had not been recorded. The $225 
million in associated unrealized losses represents 7 percent of the fixed income portfolio’s cost basis and 5 percent of total invested 

71 
assets. Isolated to these securities, unrealized losses at the end of 2024 increased compared to the previous year due to interest rates, 
beyond two years to maturity, rising over the course of the year. Of the total 1,333 securities, 1,009 have been in an unrealized loss 
position for 12 consecutive months or longer. The following table illustrates the total value of fixed income securities that were in an 
unrealized loss position as of December 31, 2024 and 2023. We believe we will recover the amortized cost basis of available-for-sale 
securities that remain in an unrealized loss position.

OTHER INVESTED ASSETS 
 
We had $58 million of other invested assets at December 31, 2024, compared to $59 million at the end of 2023. Other invested 
assets include investments in low-income housing tax credit partnerships (LIHTC) and historic tax credit partnerships (HTC), 
membership stock in the Federal Home Loan Bank of Chicago (FHLBC) and investments in private funds. Our LIHTC and HTC 
investments are carried at amortized cost and our investment in FHLBC stock is carried at cost. Due to the nature of the LIHTC, HTC 
and our membership in the FHLBC, their carrying amounts approximate fair value. The private funds are carried at fair value, using 
each investments’ net asset value. 
 
Our LIHTC interests had a balance of $7 million at December 31, 2024, compared to $10 million at December 31, 2023. Our 
LIHTC interests recognized amortization of $3 million as a component of income tax expense in 2024, 2023 and 2022 and was 
included in the net earnings line item of the statement of cash flows. Additionally, our LIHTC recognized a total tax benefit of $3 

72 
million during 2024, 2023 and 2022. Our unfunded commitment for our LIHTC investments was less than $1 million at December 31, 
2024 and will be paid out in installments through 2035. 
 
Our HTC investment had a balance of $15 million at December 31, 2024, compared to $13 million at December 31, 2023. 
Through 2022, the investment was accounted for as an investment in unconsolidated investee. Due to the adoption of ASU 2023-02, 
Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method, the investment was reclassified as 
an other invested asset during 2023. A total tax benefit of $6 million was recognized from our HTC investment during 2024, 
compared to $6 million during 2023 and $5 million during 2022. Our HTC recognized $4 million of amortization as a component of 
income tax expense during 2024 and 2023 and was included in the net earnings line item of the statement of cash flows.  
 
Our investments in private funds totaled $24 million at December 31, 2024 and $28 million at December 31, 2023. We had $4 
million of associated unfunded commitments at December 31, 2024. Our interest in private funds is generally restricted from being 
transferred or otherwise redeemed without prior consent by the respective entities and the timed dissolution of the partnerships would 
trigger redemption.  
 
Restricted Assets 
 
As of December 31, 2024, $53 million of investments were pledged as collateral with the FHLBC to ensure timely access to the 
secured lending facility that ownership of the FHLBC stock provides. On November 12, 2024, RLI Insurance Company borrowed $50 
million from the FHLBC, which was outstanding as of December 31, 2024. 
 
As of December 31, 2024, fixed income securities with a carrying value of $93 million were on deposit with regulatory 
authorities as required by law. 
 
3. DEBT 
 
As of December 31, 2024, outstanding debt balances totaled $100 million. 
 
On September 15, 2023, we accessed $50 million from our revolving line of credit with PNC Bank, N.A. (PNC). The borrowing 
may be repaid at any time and carries an adjustable interest rate of 5.98 percent as of the end of 2024. The credit facility with PNC 
was entered into during the first quarter of 2023 and replaced the previous $60 million facility with Bank of Montreal, Chicago 
Branch, which expired on March 27, 2023. The line of credit permits us to borrow up to an aggregate principal amount of $100 
million, but may be increased up to an aggregate principal amount of $130 million under certain conditions. The facility has a three-
year term that expires on May 29, 2026. 
 
On November 12, 2024, we repaid $50 million that was borrowed from the Federal Home Loan Bank of Chicago (FHLBC) in 
2023 and paid interest monthly at an annualized rate of 5.44 percent. Additionally, on November 12, 2024 we borrowed $50 million 
from the FHLBC. The borrowing matures on November 12, 2025 and monthly interest is paid at an annualized rate of 4.44 percent. 
 
Due to the lack of marketability and short tenor of our borrowings, the fair value of our debt approximates the carrying value. 
We paid $6 million of interest on our debt in 2024, compared to $9 million in 2023 and $8 million in 2022. The average rate on debt 
was 6.05 percent in 2024, 4.07 percent in 2023 and 3.89 percent in 2022. The weighted average interest rate on debt outstanding was 
5.21 percent as of December 31, 2024. 
 
4. REINSURANCE 
 
In the ordinary course of business, our insurance subsidiaries assume and cede premiums and selected insured risks with other 
insurance companies, known as reinsurance. There are several types of treaties including quota share, excess of loss and catastrophe 
reinsurance contracts that protect against losses over stipulated amounts arising from any one occurrence or event. The arrangements 
allow the Company to pursue greater diversification of business and serve to limit the maximum net loss to a single event, such as a 
catastrophe. Through the quantification of exposed policy limits in each region and the extensive use of computer-assisted modeling 
techniques, we monitor the concentration of risks exposed to catastrophic events. 
 
Through the purchase of reinsurance, we also limit our net loss on any individual risk to a maximum of $12 million, although 
retentions can vary.

All other reinsurance balances recoverable, when considered by individual reinsurer, are less than 2 percent of shareholders’ 
equity. 
 
The allowances for uncollectible amounts on paid and unpaid recoverables were $17 million and $10 million, respectively, at 
December 31, 2024 and $16 million and $11 million, respectively, at December 31, 2023. Changes in the allowances during 2024 
were due to changes in the amount of reinsurance balances outstanding, the composition of reinsurers from whom the balances were 
recoverable and their associated S&P default ratings. Less than $1 million of write-offs were applied to the allowances in 2024 and 
less than $1 million was recovered.

Loss development occurs when our current estimate of ultimate losses, established through our reserve analysis processes, 
differs from the initial reserve estimate. The recognition of the changes in initial reserve estimates occurred over time as claims were 
reported, initial case reserves were established, initial reserves were reviewed in light of additional information and ultimate payments 
were made on the collective set of claims incurred as of that evaluation date. The new information on the ultimate settlement value of 
claims is continually updated until all claims in a defined set are settled. As a specialty insurer with a diversified product portfolio, our 
experience will ordinarily exhibit fluctuations from period to period. While we attempt to identify and react to changes in the loss 
environment, we also must consider the volume of claim experience directly available to the Company and interpret any particular 
period’s indications with a realistic technical understanding of the reliability of those observations. 
 
The following is information about incurred and paid loss development as of December 31, 2024, net of reinsurance, as well as 
cumulative claim frequency, the total of IBNR liabilities included within the net incurred loss amounts and average historical claims 
duration as of December 31, 2024. The loss information has been disaggregated so that only losses that are expected to develop in a 
similar manner are grouped together. This has resulted in the presentation of loss information for our property and surety segments at 
the segment level, while information for our casualty segment has been separated in four groupings: primary occurrence, excess 
occurrence, claims made and transportation. Primary occurrence includes select lines within the professional services product along 
with general liability, small commercial and other casualty products. Excess occurrence encompasses commercial excess and personal 
umbrella, while claims made includes select lines within the professional services product, executive products and other casualty. 
Reported claim counts represent claim events on a specified policy rather than individual claimants and includes claims that did not or 
are not expected to result in an incurred loss. The information about incurred and paid claims development for the years ended 
December 31, 2015 to 2023 is presented as unaudited required supplementary information.

DETERMINATION OF IBNR 
 
Initial carried IBNR reserves are determined through a reserve estimation process. For most casualty and surety products, this 
process involves the use of an initial loss and allocated loss adjustment expense (ALAE) ratio that is applied to the earned premium 
for a given period. Payments and case reserves are subtracted from this initial estimate of ultimate loss and ALAE to determine a 
carried IBNR reserve. For most property products, the IBNR reserves are determined by IBNR percentages applied to premium 
earned. The percentages are determined based on historical reporting patterns and are updated periodically. No deductions for paid or 
case reserves are made. Shortly after natural or man-made catastrophes, we review insured locations exposed to the event and estimate 
losses based on our exposures. We also consider our knowledge of frequency and severity from early claim reports to determine an 
appropriate reserve for the catastrophe. Adjustments to the initial loss ratio by product and segment are made where necessary and 
reflect updated assumptions regarding loss experience, loss trends, price changes and prevailing risk factors. 
 
Actuaries perform a ground-up reserve study of the expected value of the unpaid loss and LAE derived using multiple standard 
actuarial methodologies on a quarterly basis. Each method produces an estimate of ultimate loss by accident year. We review all of 
these various estimates and assign weights to each based on the characteristics of the product being reviewed. These estimates are then 
compared to the carried loss reserves to determine the appropriateness of the current reserve balance. In addition, an emergence 
analysis is completed quarterly to determine if further adjustments are necessary. 
 
Upon completion of our loss and LAE estimation analysis, a review of the resulting variance between the indicated reserves and 
the carried reserves takes place. Our actuaries make a recommendation to management in regards to booked reserves that reflect their 
analytical assessment and view of estimation risk. After discussion of these analyses and all relevant risk factors, the Loss Reserve 
Committee, a panel of management including the lead reserving actuary, chief executive officer, chief operating officer, chief 
financial officer and other executives, confirms the appropriateness of the reserve balances.

A discussion of significant components of reserve development for the three most recent calendar years follows: 
 
2024. We experienced favorable emergence relative to prior years’ loss reserve estimates in all of our segments during 2024. 
Development from the casualty segment totaled $53 million. The majority of our favorable development was experienced across 
accident years 2019 through 2023. We continued to experience emergence that was generally better than previously estimated. We 
attribute the favorable emergence to loss trends in select lines outperforming our long-term expectations, our underwriters’ ability to 
select risk and an increasing rate environment. Within the primary occurrence grouping, the general liability product contributed $13 
million to our favorable development, while small commercial developed adversely by $9 million. Within the excess occurrence 
grouping, commercial excess was favorable by $18 million and personal umbrella developed favorably by $3 million. Within the 
claims made grouping, professional services coverages developed favorably by $10 million and executive products developed 
favorably by $11 million. Transportation had $8 million of adverse development. 
 
Our marine product was the predominant driver of the favorable development in the property segment, accounting for $18 
million of the $33 million total favorable development for the segment. Accident years 2021 through 2023 made the largest 
contribution. Commercial property was favorable by $10 million. 
 
The surety segment experienced $9 million of favorable development. The majority of the favorable development came from the 
2020, 2022 and 2023 accident years. Commercial and contract surety were the main contributors with favorable development of $5 
million and $5 million, respectively. 
 
2023. We experienced favorable emergence relative to prior years’ reserve estimates in all of our segments during 2023. The 
casualty segment contributed $78 million in favorable development. Accident years 2015 through 2022 contributed significantly to the 
favorable development. This was predominantly driven by favorable frequency and severity trends that were better than our long-term 
expectations. In addition, we believe this was the result of our underwriters’ ability to select risk, as well as the favorable rate 
environment within many of our casualty sublines. Nearly all of our casualty products contributed to the favorable development. 
Within the primary occurrence grouping, the general liability product contributed $13 million to our favorable development. Within 
the excess occurrence grouping, commercial excess developed favorably by $15 million and our personal umbrella product developed 
favorably by $11 million. Within the claims made grouping, professional services coverages developed favorably by $10 million and 
executive products developed favorably by $12 million. Transportation contributed $4 million for the year. 
 
Marine contributed $4 million of the $21 million total favorable property development, primarily in accident years 2020 through 
2022. Commercial property was favorable by $11 million. 
 
The surety segment experienced favorable development of $9 million. The majority of the favorable development was from 
accident year 2022. Commercial and contract surety products were the main contributors, with favorable development of $6 million 
and $3 million, respectively. 
 
2022. We experienced favorable emergence relative to prior years’ reserve estimates in all of our segments during 2022. The 
casualty segment contributed $87 million in favorable development. Accident years 2016 and 2018 through 2021 contributed the 
majority of the favorable development, with earlier years developing favorably in aggregate to a lesser extent. Risk selection by our 
underwriters continued to provide better results than estimated in our reserving process. Within the primary occurrence grouping, the 
general liability product contributed $28 million to our favorable development. Small commercial products were favorable by $5 
million. Within the excess occurrence grouping, commercial excess was favorable by $6 million and our personal umbrella product 
developed favorably by $4 million. Within the claims made grouping, professional services coverages developed favorably by $19 
million and executive products developed favorably by $4 million. Transportation experienced favorable development of $6 million. 
 
Marine contributed $17 million of the $25 million total favorable property development. Accident years 2019 through 2021 
contributed to the marine products’ favorable development. Hawaii homeowners contributed $2 million of favorable development. 

80 
 
The surety segment experienced favorable development of $10 million. The majority of the favorable development was from 
accident years 2019 through 2021. Contract surety had favorable development of $5 million and commercial surety had favorable 
development of $4 million. 
 
ENVIRONMENTAL, ASBESTOS AND MASS TORT EXPOSURES 
 
We are subject to environmental site cleanup, asbestos removal and mass tort claims and exposures through our commercial 
excess, general liability and discontinued assumed casualty reinsurance lines of business. The majority of the exposure is in the excess 
layers of our commercial excess and assumed reinsurance books of business. 
 
The following table represents paid and unpaid environmental, asbestos and mass tort claims data (including incurred but not 
reported losses) as of December 31, 2024, 2023 and 2022:

Our environmental, asbestos and mass tort exposure is limited, relative to other insurers, as a result of entering the affected 
liability lines after the insurance industry had already recognized environmental and asbestos exposure as a problem and adopted 
appropriate coverage exclusions. The majority of our reserves are associated with products that went into runoff at least three decades 
ago.  
 
While our environmental exposure is limited, the ultimate liability for this exposure is difficult to assess because of the 
extensive and complicated litigation involved in the settlement of claims and evolving legislation on issues such as joint and several 
liability, retroactive liability and standards of cleanup. Additionally, we participate primarily in the excess layers of coverage, where 
accurate estimates of ultimate loss are more difficult to derive than for primary coverage.

Effective rates are dependent upon components of pretax earnings and the related tax effects. The effective rate was slightly 
lower in 2024 due to higher levels of tax-favored adjustments. 
 
Our net earnings include equity in earnings of unconsolidated investees. The investees do not have a policy or pattern of paying 
dividends. As a result, we record a deferred tax liability on the earnings at the corporate capital gains rate of 21 percent in anticipation 
of recovering our investments through means other than through the receipt of dividends, such as a sale. We received a $3 million 
dividend from Prime in 2024 and recognized less than $1 million of tax benefit from applying the lower tax rate applicable to 
affiliated dividends paid to insurance companies (10.8 percent), as compared to the corporate capital gains rate on which the deferred 
tax liabilities were based. No dividends were declared from Prime in 2023 or 2022, therefore having no impact to their respective 
effective tax rates. 
 
Dividends paid to our Employee Stock Ownership Plan (ESOP) also result in a tax deduction. Dividends paid to the ESOP in 
2024, 2023 and 2022 resulted in tax benefits of $3 million, $2 million and $4 million, respectively. These tax benefits reduced the 
effective tax rate for 2024, 2023 and 2022 by 0.6 percent, 0.4 percent and 0.6 percent, respectively. 

82 
 
We have recorded our deferred tax assets and liabilities using the statutory federal tax rate of 21 percent. We believe it is more 
likely than not that all deferred tax assets will be recovered, given the carry back availability as well as the projected results of future 
operations, which we believe will generate sufficient taxable income to realize the deferred tax asset. In addition, we believe when 
these deferred items reverse in future years, our taxable income will be taxed at an effective rate of 21 percent. 
 
Federal and state income taxes paid in 2024, 2023 and 2022 amounted to $68 million, $50 million and $190 million, 
respectively. The larger amount paid in 2022 was the result of taxes paid on the sale of our investment in Maui Jim. See note 12 to the 
consolidated financial statements for more information on the sale. 
 
Although we are not currently under audit by the IRS, tax years 2021 through 2024 remain open and are subject to examination. 
 
7. EMPLOYEE BENEFITS 
 
EMPLOYEE STOCK OWNERSHIP, 401(K) AND INCENTIVE PLANS 
 
We maintain ESOP, 401(k) and incentive plans covering executives, managers and associates. Funding of these plans is 
primarily dependent upon reaching predetermined levels of operating return on equity, combined ratio and Market Value Potential 
(MVP). MVP is a compensation model that measures components of comprehensive earnings against a minimum required return on 
our capital. Bonuses are earned as we generate earnings in excess of this required return. While some management incentive plans 
may be affected somewhat by other performance factors, the larger influence of corporate performance ensures that the interests of our 
executives, managers and associates align with those of our shareholders. 
 
Our 401(k) plan allows voluntary contributions by employees and permits ESOP diversification transfers for employees meeting 
certain age and service requirements. We provide a basic 401(k) contribution of 3 percent of eligible compensation. Participants are 
100 percent vested in both voluntary and basic contributions. Additionally, an annual discretionary profit-sharing contribution may be 
made to the ESOP and 401(k), subject to the achievement of certain overall financial goals and board approval. Profit-sharing 
contributions vest after three years of plan service. 
 
Our ESOP and 401(k) cover all employees meeting eligibility requirements. ESOP and 401(k) profit-sharing contributions are 
approved annually by our board of directors and are expensed in the year earned. ESOP and 401(k)-related expenses (basic and profit-
sharing) were $25 million, $23 million and $18 million for 2024, 2023 and 2022, respectively. 
 
During 2024, the ESOP purchased 149,696 shares of RLI Corp. stock on the open market at an average price of $73.62 ($11 
million) relating to the contribution for plan year 2023. Shares held by the ESOP as of December 31, 2024, totaled 4,749,542 and are 
treated as outstanding in computing our earnings per share. During 2023, the ESOP purchased 131,546 shares of RLI Corp. stock on 
the open market at an average price of $68.21 ($9 million) relating to the contribution for plan year 2022. During 2022, the ESOP 
purchased 174,734 shares of RLI Corp. stock on the open market at an average price of $51.51 ($9 million) relating to the contribution 
for plan year 2021. The above-mentioned ESOP purchases relate only to our annual contributions to the plan and do not include 
amounts or shares resulting from the reinvestment of dividends. 
 
Annual awards are provided to executives, managers and associates through our incentive plans, provided certain strategic and 
financial goals are met. Annual expenses for these incentive plans totaled $44 million, $38 million and $24 million for 2024, 2023 and 
2022, respectively. Incentive-based compensation received by current or former executive officers is subject to clawback in the event 
of an accounting restatement. 
 
DEFERRED COMPENSATION 
 
We maintain rabbi trusts for deferred compensation plans for directors, key employees and executive officers through which 
contributions can be invested in RLI Corp. stock or mutual funds. The employer stock in the plan cannot be diversified and is 
accounted for as equity, in a manner consistent with the accounting for treasury stock. At December 31, 2024, the trusts’ assets were 
valued at $69 million. 
 
STOCK PLANS 
 
Our RLI Corp. Long-Term Incentive Plan (2015 LTIP) was in place from 2015 to 2023. The 2015 LTIP provided for equity-
based compensation, including stock options and restricted stock units, up to a maximum of 8,000,000 shares of common stock 

83 
(subject to adjustment for changes in our capitalization and other events). Between 2015 and 2023, we granted 6,582,776 stock 
options under the 2015 LTIP. The 2015 LTIP was replaced in 2023. 
 
In 2023, our shareholders approved the 2023 RLI Corp. Long-Term Incentive Plan (2023 LTIP), which provides for equity-
based compensation. In conjunction with the adoption of the 2023 LTIP, effective May 4, 2023, awards were no longer granted under 
the 2015 LTIP. Awards under the 2023 LTIP may be in the form of restricted stock, restricted stock units, stock options (incentive or 
non-qualified), stock appreciation rights, performance units as well as other stock-based awards. Eligibility under the 2023 LTIP is 
limited to employees, directors, consultants and independent contractors of the Company or any affiliate. The granting of awards 
under the 2023 LTIP is solely at the discretion of the Human Capital and Compensation Committee of the board of directors or its 
delegate. The maximum number of shares of common stock available for distribution under the 2023 LTIP is 8,009,782 shares 
(subject to adjustment for changes in our capitalization and other events). Since the plan’s approval in 2023, we have granted 813,182 
awards under the 2023 LTIP. 
 
Compensation expense is based on the probable number of awards expected to vest. The total compensation expense related to 
equity awards was $8 million, $9 million and $9 million for 2024, 2023 and 2022, respectively. The total income tax benefit was $1 
million for 2024, 2023 and 2022. Total unrecognized compensation expense relating to outstanding and unvested awards was $7 
million, which will be recognized over the weighted average vesting period of 2.60 years. 
 
Stock Options 
 
Under the 2023 LTIP, as under the 2015 LTIP, we grant stock options for shares with an exercise price equal to the fair market 
value of the shares at the date of grant (subject to adjustments for changes in our capitalization, including special dividends and other 
events as set forth in such plans). Options generally vest and become exercisable ratably over a five-year period and expire eight years 
after grant. 
 
For most participants, the requisite service period and vesting period will be the same. For participants who are retirement 
eligible, defined by the plan as those individuals whose age and years of service equals 75 or more, the requisite service period is 
deemed to be met and options are immediately expensed on the date of grant. For participants who will become retirement eligible 
during the vesting period, the requisite service period over which expense is recognized is the period between the grant date and the 
attainment of retirement eligibility. Shares issued upon option exercise are newly issued shares.

The risk-free rate was determined based on U.S. treasury yields that most closely approximated the option’s expected life. The 
dividend yield was determined based on the average annualized quarterly dividends paid during the most recent five-year period and 
incorporated a consideration for special dividends paid in recent history. The expected volatility was calculated based on the median 
of the rolling volatilities for the expected life of the options. The expected option life was determined based on historical exercise 
behavior and the assumption that all outstanding options will be exercised at the midpoint of the current date and remaining 
contractual term, adjusted for the demographics of the current year’s grant. 
 
Restricted Stock Units 
 
In addition to stock options, restricted stock units (RSUs) are granted with a value equal to the closing stock price of the 
Company’s stock on the dates the units are granted. For employees, these units generally have a three-year cliff vesting, but have an 
accelerated vesting feature for participants who are retirement eligible, defined by the plan as those individuals whose age and years of 
service equals 75 or more. For directors, these units vest on the earlier of one year from the date of grant or the next annual 
shareholders meeting. In addition, the RSUs have dividend participation, which accrue as additional units and are settled with granted 
stock units at the end of the vesting period. The total fair value of restricted stock units that vested was $2 million, $3 million and $2 
million during 2024, 2023 and 2022, respectively.

8. STATUTORY INFORMATION AND DIVIDEND RESTRICTIONS 
 
The statutory financial statements of our three insurance companies are presented on the basis of accounting practices prescribed 
or permitted by the Illinois Department of Insurance (IDOI), which has adopted the NAIC’s statutory accounting principles (SAP). We 
do not use any permitted SAP that differ from NAIC prescribed SAP. In converting from SAP to GAAP, typical adjustments include 
deferral of policy acquisition costs, the inclusion of statutory non-admitted assets and the inclusion of net unrealized holding gains or 
losses in shareholders’ equity relating to fixed income securities. 
 
The NAIC has risk-based capital (RBC) requirements for insurance companies to calculate and report information under a risk-
based formula, which measures statutory capital and surplus needs based upon a regulatory definition of risk relative to the company’s 
balance sheet and mix of products. As of December 31, 2024, each of our insurance subsidiaries had an RBC amount in excess of the 
authorized control level RBC, as defined by the NAIC. RLI Insurance Company (RLI Ins.), our principal insurance company 
subsidiary, had an authorized control level RBC of $296 million, $273 million and $250 million as of December 31, 2024, 2023 and 
2022, respectively, compared to actual statutory capital and surplus of $1.8 billion, $1.5 billion and $1.4 billion, respectively, for these 
same periods. 
 
Year-end statutory surplus for 2024 presented in the table below includes $352 million of RLI Corp. stock (cost basis of $65 
million) held by Mt. Hawley Insurance Company, compared to $294 million and $327 million in 2023 and 2022, respectively. The 
Securities Valuation Office provides specific guidance for valuing this investment, which is eliminated in our GAAP consolidated 
financial statements. 
 
The following table includes selected information for our insurance subsidiaries for the year ended and as of December 31:

As discussed in note 1.A., our three insurance companies are subsidiaries of RLI Corp., with RLI Ins. as the first-level, or 
principal, insurance subsidiary. At the holding company (RLI Corp.) level, we rely largely on dividends from our insurance company 
subsidiaries to meet our obligations for paying principal and interest on outstanding debt, corporate expenses and dividends to RLI 

85 
Corp. shareholders. As discussed further below, dividend payments to RLI Corp. from RLI Ins. are restricted by state insurance laws 
as to the amount that may be paid without prior approval of the insurance regulatory authorities of Illinois. As a result, we may not be 
able to receive dividends from such subsidiary at times and in amounts necessary to pay desired dividends to RLI Corp. shareholders. 
On a GAAP basis, as of December 31, 2024, our holding company had $1.5 billion in equity. This includes amounts related to the 
equity of our insurance subsidiaries, which is subject to regulatory restrictions under state insurance laws. The unrestricted portion of 
holding company net assets is comprised primarily of investments and cash, including $39 million in liquid assets, which 
approximates two-thirds of our normal annual holding company expenditures. Unrestricted funds at the holding company are available 
to fund debt interest, general corporate obligations and regular dividend payments to our shareholders. If necessary, the holding 
company also has other potential sources of liquidity that could provide for additional funding to meet corporate obligations or pay 
shareholder dividends, which include a revolving line of credit, as well as access to capital markets. 
 
Ordinary dividends, which may be paid by our principal insurance subsidiary without prior regulatory approval, are subject to 
certain limitations based upon statutory income, surplus and earned surplus. The maximum ordinary dividend distribution from our 
principal insurance subsidiary in a rolling 12-month period is limited by Illinois law to the greater of 10 percent of RLI Ins. 
policyholder surplus, as of December 31 of the preceding year, or the net income of RLI Ins. for the 12-month period ending 
December 31 of the preceding year. Ordinary dividends are further restricted by the requirement that they be paid from earned surplus. 
In 2024, 2023 and 2022, RLI Ins. paid ordinary dividends totaling $152 million, $145 million and $13 million, respectively, to RLI 
Corp. Any dividend distribution in excess of the ordinary dividend limits is deemed extraordinary and requires prior approval from the 
IDOI. No extraordinary dividends were paid in 2024, 2023 or 2022. Although RLI Ins. was restricted from distributing ordinary 
dividends to RLI Corp. as of December 31, 2024, the rolling 12-month limitations reset as of January 1st. A total of $241 million in 
ordinary dividend capacity will be available over the course of 2025. In addition to restrictions from our principal subsidiary’s 
insurance regulator, we also consider internal models and how capital adequacy is defined by our rating agencies in determining 
amounts available for distribution. 
 
9. COMMITMENTS AND CONTINGENT LIABILITIES 
 
COMMITMENTS 
 
As of December 31, 2024, we had $8 million of unfunded commitments related to our investments in private funds and tax 
credits. See note 2 to the consolidated financial statements for more information on our investments in private funds and low-income 
housing tax credits. 
 
LITIGATION 
 
We are party to numerous claims, loss and litigation matters that arise in the normal course of our business. Many of such 
claims, loss or litigation matters involve claims under policies that we underwrite as an insurer. We believe that the resolution of these 
claims and losses is not reasonably likely to have a material adverse effect on our financial condition, results of operations or cash 
flows. From time to time, we are also involved in various other legal proceedings and litigation unrelated to our insurance business 
that arise in the ordinary course of business operations. Management believes that any liabilities that may arise as a result of these 
legal matters is not reasonably likely to have a material adverse effect on our financial condition, results of operations or cash flows. 
 
10. LEASES 
 
Right-of-use (ROU) assets are included in the other assets line item and lease liabilities are included in the other liabilities line 
item of the consolidated balance sheet. We determine if a contract contains a lease at inception and recognize operating lease ROU 
assets and operating lease liabilities based on the present value of the future minimum lease payments at the commencement date. As 
our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the 
commencement date in determining the present value of future payments. Lease agreements may include options to extend or 
terminate. The options are exercised at our discretion and are included in operating lease liabilities if it is reasonably certain the option 
will be exercised. Lease agreements have lease and non-lease components, which are accounted for as a single lease component. 
Operating lease costs for future minimum lease payments are recognized on a straight-line basis over the lease terms. Variable lease 
costs are expensed in the period in which the obligations are incurred. Sublease income is recognized on a straight-line basis over the 
sublease term.

2022 were as follows:

11. OPERATING SEGMENT INFORMATION 
 
The Company’s insurance operations are managed and reported in three operating segments: property, casualty and surety. The 
casualty portion of our business consists largely of commercial excess, personal umbrella, general liability, transportation and 
management liability coverages, as well as package business and other specialty coverages, such as professional liability and workers’ 
compensation for office-based professionals. We also assume a limited amount of risks through quota share and excess of loss 
reinsurance agreements. The casualty business is subject to a higher level of risk when estimating losses and related loss reserves 
because the ultimate settlement of a casualty claim may take several years to fully develop.  
 
Our property segment is comprised primarily of commercial fire, hurricane, earthquake, difference in conditions and marine 
coverages. We also offer homeowners’ coverages in Hawaii. Property insurance results are subject to the variability introduced by 
perils such as earthquakes, fires, hurricanes and other storms. Our major catastrophe exposure is to losses caused by windstorms, 
affecting commercial properties in coastal regions of the United States, and earthquakes, primarily on the West Coast. We limit our 
net aggregate exposure to a catastrophic event by managing the total policy limits written in a particular region, purchasing 
reinsurance and maintaining policy terms and conditions throughout all insurance cycles. We also use computer-assisted modeling 
techniques to provide estimates that help the Company carefully manage the concentration of risks exposed to catastrophic events. 
 
The surety segment specializes in writing small to medium-sized contract surety coverages, including payment and performance 
bonds. We offer a variety of commercial surety bonds for medium to large-sized businesses across a broad spectrum of industries, 
including the financial, healthcare, energy and renewable energy industries. We also offer a variety of transactional bonds including, 
but not limited to license and permit, notary and court bonds. Often, our surety coverages involve a statutory requirement for bonds. 
While these bonds typically maintain a relatively low loss ratio, losses may fluctuate due to adverse economic conditions affecting the 

87 
financial viability of our insureds. The contract surety product guarantees commercial contractors’ contractual obligations for a 
specific construction project. Generally, losses occur due to the deterioration of a contractor’s financial condition. 
 
The Company’s chief operating decision maker (CODM) is the chief executive officer. The Company’s CODM assesses the 
segments’ performance by using earnings before income taxes (underwriting income) and the combined ratio. Underwriting income 
and combined ratio are analyzed at the segment level and influence how resources are allocated. Decisions are made based on what is 
likely to provide the best long-term return to the Company. 
 
The accounting policies of the reporting segments are the same as those described in note 1 to the consolidated financial 
statements. Expense allocations are based on assumptions primarily related to direct costs, net premiums earned, as well as the level of 
support required for the products within each segment. Amortization of deferred acquisition costs represents the recognition of 
commission and premium taxes over the life of insurance polices, in proportion to premium revenue recognized. The other policy 
acquisition costs line item includes other expenses associated with underwriting, but that cannot be specifically associated with the 
successful acquisition of a policy, including, but not limited to, employment costs for underwriters and underwriting support as well as 
costs for policy acquisition systems. Insurance operating expenses reflect allocated costs from various support departments, such as 
corporate technology, accounting, human resources and facilities, among others.  
 
Net investment income consists of the interest and dividend income streams from our investments in fixed income and equity 
securities. Interest expense represents the cost of debt and lines of credit. General corporate expenses include director and shareholder 
relation costs and other compensation-related expenses incurred for the benefit of the corporation, but not attributable to the operations 
of our insurance segments. Investee earnings primarily represents our 23 percent share in earnings of Prime Holdings Insurance 
Services, Inc., a privately held insurance company which specializes in hard-to-place risks. Assets, and the revenues and expenses 
associated with investing and financing activities, are not managed at the segment level and therefore are not allocated to segments. 
 
All segment revenues are from external customers and all long-lived assets are held domestically. We have no material foreign 
operations or customer concentrations and have no intersegment revenues.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 
 
To the shareholders and the Board of Directors of RLI Corp. 
 
Opinions on the Financial Statements and Internal Control over Financial Reporting 
 
We have audited the accompanying consolidated balance sheets of RLI Corp. and subsidiaries (the “Company”) as of December 31, 
2024 and 2023, the related consolidated statements of earnings and comprehensive earnings, shareholders’ equity, and cash flows, for 
each of the three years in the period ended December 31, 2024, and the related notes and the schedules listed in the Index at Item 15 
(collectively referred to as the “financial statements”). We also have audited the Company’s internal control over financial reporting 
as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee 
of Sponsoring Organizations of the Treadway Commission (COSO). 
 
In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company 
as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended 
December 31, 2024, in conformity with accounting principles generally accepted in the United States of America. Also, in our 
opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, 
based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO. 
 
Basis for Opinions 
 
The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial 
reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying 
Management’s Report on Internal Controls Over Financial Reporting. Our responsibility is to express an opinion on these financial 
statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting 
firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent 
with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the 
Securities and Exchange Commission and the PCAOB. 
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits 
to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, 
and whether effective internal control over financial reporting was maintained in all material respects. 
Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial 
statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, 
on a test basis, evidence regarding the amounts and disclosures in the 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 
financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over 
financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness 
of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary 
in the circumstances. We believe that our audits provide a reasonable basis for our opinions. 
 
Definition and Limitations of Internal Control over Financial Reporting 
 
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of 
financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting 
principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the 
maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the 
company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in 
accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in 
accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding 
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect 
on the financial statements. 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections 
of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in 
conditions, or that the degree of compliance with the policies or procedures may deteriorate. 
 

91 
Critical Audit Matter 
 
The critical audit matter communicated below is a matter arising from the current-period audit of the 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 financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of 
critical audit matters does not alter in any way our opinion on the 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. 
 
Unpaid losses and settlement expenses — Refer to Notes 1 and 5 to the financial statements 
 
Critical Audit Matter Description 
 
The liability for unpaid losses and settlement expenses represents estimates of amounts needed to pay reported and unreported claims 
and related expenses. The estimates are based on certain actuarial and other assumptions related to the ultimate cost to settle such 
claims. 
We identified the assessment of the Company’s estimate of unpaid losses and settlement expenses as a critical audit matter. 
Specialized actuarial skills and knowledge were required to assess the methodologies and assumptions used to estimate unpaid losses 
and settlement expenses. The assumptions used by the Company to estimate unpaid losses and settlement expenses included expected 
loss ratios, loss development patterns, qualitative factors, and the weighting of actuarial methodologies. These assumptions included a 
range of potential inputs and changes to these assumptions could affect the estimate of unpaid losses and settlement expenses recorded 
by the Company. 
 
How the Critical Audit Matter Was Addressed in the Audit 
 
Our audit procedures related to unpaid losses and settlement expenses included the following, among others: 
 
 
We tested the effectiveness of controls related to unpaid losses and settlement expenses, including those controls over the 
inputs, methods, and assumptions used in the Company’s estimation processes. 
 
We tested the underlying data, including historical claims, that served as the basis for the actuarial analyses, to test that the 
inputs to the actuarial estimates were accurate and complete. 
 
With the assistance of our actuarial specialists, we evaluated the methods and assumptions used by the Company to estimate 
the unpaid losses and settlement expenses by: 
 
o 
Developing a range of independent estimates of unpaid losses and settlement expenses for certain lines of business 
and comparing our estimates to the recorded reserves. 
 
o 
We compared our prior year estimates of expected incurred losses to actual experience during the current year to 
identify potential management bias in the determination of the unpaid losses and settlement expenses.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure 
 
There were no changes in accountants or disagreements with accountants on any matters of accounting principles or practices or 
financial statement disclosure. 
 
Item 9A. Controls and Procedures 
 
Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures 
 
Under the supervision and with the participation of our management, including our principal executive officer and principal 
financial officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined under 
Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the Exchange Act). Based on this evaluation, 
our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures were effective 
as of December 31, 2024. 
 
Management’s Report on Internal Control Over Financial Reporting 
 
Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term 
is defined in Exchange Act Rules 13a-15(f). Under the supervision and with the participation of our management, including our 
principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over 
financial reporting based on the framework in Internal Control — Integrated Framework (2013) issued by the Committee of 
Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control — 
Integrated Framework (2013), our management concluded that our internal control over financial reporting was effective as of 
December 31, 2024. 
 
Our internal control over financial reporting as of December 31, 2024 has been audited by Deloitte & Touche LLP (PCAOB ID 
No. 34), an independent registered public accounting firm, as stated in their report on page 90 of this report. 
 
There was no change in our internal control over financial reporting during our fourth fiscal quarter ended December 31, 2024 
that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. 
 
Item 9B. Other Information  
 
Securities Trading Plans of Executive Officers and Directors 
 
Rule 10b5-1 under the Exchange Act provides an affirmative defense that enables prearranged transactions in Company 
securities in a manner that avoids concerns about initiating transactions at a future date while possibly in possession of material 
nonpublic information. Our Insider Trading Policy permits our executive officers and directors to enter into trading plans designed to 
comply with Rule 10b5-1. 
 
During the year ended December 31, 2024, no director or officer of the Company adopted or terminated a Rule 10b5-1 trading 
arrangement or non-Rule 10b5-1 trading arrangement, as each term is defined in Item 408(a) of Regulation S-K.

I have reviewed this annual report on Form 10-K of RLI Corp. 
Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary 
to make the statements made, in light of the circumstances under which such statements were made, not misleading with respect to the

Based on my knowledge, the financial statements, and other financial information included in this report, fairly present in all material 
respects the financial condition, results of operations and cash flows of the registrant as of, and for, the periods presented in this 
report; 
The registrant’s other certifying officer and I are responsible for establishing and maintaining disclosure controls and procedures (as 
defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as defined in Exchange Act 
Rules 13a-15(f) and 15d-15(f)) for the registrant and have: 
(a) designed such disclosure controls and procedures, or caused such disclosure controls and procedures to be designed under our 
supervision, to ensure that material information relating to the registrant, including its consolidated subsidiaries, is made known 
to us by others within those entities, particularly during the period in which this report is being prepared; 
(b) designed such internal control over financial reporting, or caused such internal control over financial reporting to be designed 
under our supervision, 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;

reporting, to the registrant’s auditors and the audit committee of the registrant’s board of directors (or persons performing the

information; and 
(b) any fraud, whether or not material, that involves management or other employees who have a significant role in the 
registrant’s internal control over financial reporting.
