Item 1.  BUSINESS

(a)       General Development of Business

          As used in this Form 10-K, the term "Company" refers to RLI Corp. and
its subsidiaries and affiliates, unless the context otherwise indicates.

          RLI Corp., which was incorporated in Illinois in 1965, merged into and
became a Delaware corporation in 1984.  In May of 1993, RLI Corp. changed its
state of incorporation back to Illinois through a merger.  RLI Corp. is a
holding company, which, through its subsidiaries, underwrites selected property
and casualty insurance.

(b)       Financial Information about Industry Segments

          Selected information about industry segments is included herein as 
Item 8.

(c)       Narrative Description of Business


                                 RLI INSURANCE GROUP

          RLI Insurance Group is composed primarily of two main insurance 
companies. RLI Insurance Company, the principal subsidiary, writes multiple 
lines of insurance on an admitted basis in all 50 states, the District of 
Columbia and Puerto Rico.  Mt. Hawley Insurance Company, a subsidiary of RLI 
Insurance Company, writes multiple lines of insurance on an admitted basis in 
Kansas and surplus lines insurance in the remaining 49 states, the District 
of Columbia, Puerto Rico, the Virgin Islands and Guam.  Other companies in 
the RLI Insurance Group include: Replacement Lens Inc., RLI Aviation, Inc., 
RLI Insurance Agency, Ltd., and RLI Insurance Ltd.

          Since 1977, when the Company first began underwriting specialty 
property and casualty coverages for commercial risks, highly cyclical market 
conditions and a number of other factors have influenced the Company's growth 
and underwriting profits.  The Company, as a "niche" company rather than an 
"all lines" company, seeks to develop expertise and large homogeneous books 
of business in areas generally overlooked by traditional markets.             

        In response to the soft market conditions of the early 1980's, which 
were characterized by severe rate competition and excess underwriting 
capacity, the Company limited its writings in specialty property and casualty 
lines and terminated certain lines and sources of production.

          Significant rate increases resulted when the insurance market 
hardened in late 1984.  The Company responded by expanding its premium volume 
in targeted lines.  Since 1987, the industry has experienced generally soft 
market conditions featuring intensified competition for admitted and surplus 
lines insurers, resulting in rate decreases.  The Company has continually 
monitored its rates and controlled its costs in an effort to maximize profits 
during this entrenched soft market condition.  As a result of Hurricane 
Andrew and other catastrophic losses, especially the Northridge Earthquake of 
January 17, 1994, property rates hardened in California, Florida and the wind 
belt, but remain soft in other areas of the country.  During 1994, the 
Company secured rate increases of over 30% on the commercial property book of 
business, while the casualty book of business incurred flat to moderate 
decreases.  During 1995, rates for catastrophic driven property business, 
especially in California, continued to remain hard.  Since 1996, as expected, 
competition has reappeared for this type of business and the Company has 
reduced rates somewhat.  The Company's casualty book has continued to incur 
flat to moderate rate decreases.                                           
                                      2

          The Company initially began to write specialty property and 
casualty insurance primarily through independent underwriting agents.  
However, with the opening of its first branch office in 1984, the Company 
began to shift its marketing efforts from independent underwriting agents to 
wholly-owned branch offices which market to wholesale producers.  The Company 
also markets certain products to retail producers from its Specialty 
Marketing Division located at the home office.  The Company produced business 
under agreements with four underwriting general agents in 1997. The majority 
of its specialty property and casualty business is marketed through its 
Specialty Markets and Surety divisions and eleven branch offices located in 
Los Angeles, California; San Diego, California; San Francisco, California; 
St. Paul, Minnesota; Overland Park, Kansas; Glastonbury, Connecticut; 
Atlanta, Georgia; Alpharetta, Georgia; Chicago, Illinois; Dallas, Texas; and 
Honolulu, Hawaii.  

          The following table provides for the year ended December 31, 1997 the
geographic distribution of the Company's risks insured as represented by direct
premiums earned for all product lines.  For the year ended December 31, 1997, no
other state accounted for more than 2% of total direct premiums earned for all
product lines.

</TABLE>

          The Company presently underwrites selected property and casualty 
insurance primarily in the following lines:

          COMMERCIAL PROPERTY.  The Company's commercial property coverage 
consists primarily of excess and surplus lines and specialty insurance such 
as fire and difference in conditions which includes earthquake, flood and 
collapse coverages.  The Company writes coverage for a wide range of 
commercial and industrial classes such as office buildings, apartments, 
condominiums, certain industrial and mercantile structures, and buildings 
under construction.  The St. Paul, Los Angeles, Glastonbury, Overland Park, 
San Francisco, Chicago, Columbus and Alpharetta branch offices are 
responsible for underwriting this coverage. In  1997, 1996, and 1995, net 
earned premiums totaled $48,799,000, $47,822,000, and $49,430,000 or 29%, 
31%, and 32% respectively, of the Company's consolidated revenues.

          GENERAL LIABILITY.  The Company writes general liability coverages 
through its St. Paul, Glastonbury, Chicago, Alpharetta and Dallas branch 
offices.  The Company's general liability business consists primarily of 
coverage for third party liability of commercial insureds including 
manufacturers, contractors, apartments and mercantile.  Net earned premiums 
totaled $26,332,000, $34,834,000, and $36,499,000, or 16%, 22%, and 23% of 
the Company's consolidated revenues for the years 1997, 1996, and 1995, 
respectively.

                                       3

<PAGE>

          COMMERCIAL AND PERSONAL UMBRELLA LIABILITY.  The Company's 
commercial umbrella coverage is produced through its Overland Park, St. Paul, 
Alpharetta, Glastonbury, and Dallas branch offices, and through an 
underwriting general agency in San Francisco.  The coverage is principally 
written in excess of primary liability insurance provided by other carriers 
and, to a small degree, in excess of primary liability written by the 
Company.  The personal umbrella coverage, which is produced through the 
Specialty Markets Division, is written in excess of the homeowners and 
automobile liability coverage provided by other carriers.  Net earned 
premiums totaled $22,566,000, $21,282,000, and $18,092,000 or 12%, 14%, and 
12% of the Company's consolidated revenues for the years 1997, 1996, and 
1995, respectively.

          DIRECTORS' AND OFFICERS' LIABILITY/MISCELLANEOUS PROFESSIONAL 
LIABILITY. The Company produces Directors' and Officers' Liability through 
its underwriting facility in San Diego, California.  In 1996, the facility 
expanded to offer Miscellaneous Professional Liability for a variety of low 
to moderate classes of risks.  Net earned premiums totaled $4,430,000, 
$5,000,000, and $6,025,000, or 3%, 3%, and 4% of the Company's consolidated 
revenues for the years 1997, 1996, and 1995, respectively.

          EMPLOYER'S EXCESS INDEMNITY.  Since 1993, the Company has written 
Employer's Excess Indemnity coverage for businesses which have opted out of 
the Workers' Compensation plan in the state of Texas.  The coverage is 
similar to accident and health, in that it indemnifies the employer for 
expenses resulting from a work related injury or disease, excess of a 
self-insured retention (SIR). The SIR can range from $50,000 to $500,000. The 
product is underwritten out of the Overland Park branch office.  A return to 
excessive competition for Texas workers' compensation business has reduced 
the market for this product since 1996.  Net earned premiums totaled 
$5,130,000, $6,566,000, and $8,257,000, or 3%, 4%, and 5% of the Company's 
consolidated revenues for 1997, 1996, and 1995, respectively.

          SURETY.  In 1993, the Company began writing surety business.  This 
product line is underwritten from the Home Office in Peoria and through the 
Dallas, Texas branch office.  The initial target market of the Surety 
Division was a wide range of commercial surety bonds written primarily 
through the independent agency system.  In 1996, the Company expanded their 
product offering to include contract bonds for small size contractors.  Net 
earned premiums totaled $$11,491,000, $4,407,000, and $2,956,000, or 8%, 3%, 
and 2% of the Company's consolidated revenues for 1997, 1996, and 1995, 
respectively.

          HOMEOWNERS/RESIDENTIAL PROPERTY.  In 1997, the Company assumed a 
highly profitable book of homeowners and dwelling fire business for Hawaii 
homeowners from the Hawaii Property Insurance Association.  In the aftermath 
of Hurricane Iniki in 1992, this business was available at reasonable rates 
and terms.  Net earned premiums totalled $13,229,000 or 8% of the Company's 
consolidated revenues for the 1997 year.

          TRANSPORTATION.  In 1997, the Company opened a transportation 
insurance facility in Atlanta to offer automobile liability and physical 
damage insurance to local, intermediate and long haul truckers, public 
transportation risks and equipment dealers.  Incidental, related insurance 
coverages are also offered, including general liability, commercial umbrella 
and excess liability, and motor truck cargo.  The facility is staffed by 
highly experienced transportation underwriters who will produce business 
through independent agents and brokers nationwide.  The facility will begin 
generating premium income in 1998.

          OTHER.  Smaller programs offered by the Company include: primary 
employer's indemnity, excess medical, commercial multi-peril, in-home 
business, and accident and health insurance.  Net earned premiums from these 
lines totaled $9,907,000, $10,744,000, and $12,209,000 or 5%, 7%, and 8% of 
the Company's consolidated revenues for the years, 1997, 1996, and 1995, 
respectively.

          In June of 1995, a new facility was opened in Columbus, Ohio 
specializing in writing single interest inland marine property insurance for 
major lending institutions.  This insurance covers the institution's interest 
in property used as collateral for loans, in the event of the borrower's 
default.  This facility was closed October, 1997, and the coverage is 
currently underwritten with the Atlanta branch office.

COMPETITION

          The Company's specialty property and casualty insurance 
subsidiaries are part of an extremely competitive industry which is cyclical 
and 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 3,500 
companies, both stock and mutual, actively market property and casualty 
products.  The combination of products, service, pricing and other methods of 
competition vary from line to line.  The Company's principal methods of 
meeting this competition are innovative products, marketing structure and 
quality service to the agents and policyholders at a fair price.  The Company 
competes favorably in part because of its sound financial base and 
reputation, as well as its broad geographic penetration into all 50 states, 
the District of Columbia and Puerto Rico.  In the property and casualty area, 
the Company has acquired experienced underwriting specialists in its branch 
and home offices.  In 1987, the insurance industry, in general, entered into 
a "soft" or highly competitive period during which insurance rates generally 
decreased.  The specialty property and casualty market continues to be soft 
with some rate increases experienced in the property lines in California, 
Florida and the wind belt from 1993 through 1995.  In 1996, and continuing 
through 1997, some rate softening occurred in these property lines as 
competition reappeared.  As a result, the Company reduced rates somewhat.  
The Company has, however, continued to maintain its underwriting and 
marketing standards by not seeking market share at the expense of earnings.  
New products and new programs are offered where the opportunity exists to 
provide needed insurance coverage with exceptional service on a profitable 
basis.

RATINGS

          During 1992, the A.M. Best rating for RLI Insurance Company, the 
principal subsidiary of the Company, was upgraded to "A" (Excellent).  During 
1993, Mt. Hawley Insurance Company's (an indirect subsidiary of the Company) 
A.M. Best rating was upgraded from "A-" (Excellent) to "A" (Excellent).  
During 1997, A.M. Best reaffirmed "A" (Excellent) ratings for both RLI 
Insurance Company and Mt. Hawley Insurance Company.  

          Ratings for the industry range from "A++" (Superior) to "F" (In
Liquidation) with some companies not being rated.  Publications of A.M. Best
indicate that the "A" and "A-" (Excellent) ratings are assigned to those
companies that in A.M. Best's opinion have achieved excellent overall
performance when compared to the standards established by A.M. Best and have a
strong ability to meet their obligations to policyholders over a long period of
time.  In evaluating a company's financial and operating performance, A.M. Best
reviews the company's profitability leverage and liquidity as well as the
company's spread of risk, the quality and appropriateness of its reinsurance,
the quality and diversification of its assets, the adequacy of its policy or
loss reserves, the adequacy of its surplus, its capital structure and the
experience and objectives of its management.  A.M. Best's ratings are based on
factors relevant to policyholders, agents, insurance brokers and intermediaries
and are not directed to the protection of investors.

          In conjunction with RLI Corp.'s July, 1993 issuance of $46 million 
of 6.00% Convertible Debentures due 2003, the Company applied for and 
received a debt rating from two major debt rating agencies. Both Standard & 
Poor's Ratings Group and Moody's Investor Service assigned investment grade 
ratings to the issue.  In July, 1997, the Company called for redemption the 
entire $46 million issue.  As of December 31, 1997, the Company had no public 
debt outstanding.

REINSURANCE

          The Company reinsures a significant portion of its property and 
casualty insurance exposure, paying to the reinsurer a portion of the 
premiums received on such policies.  Earned premiums ceded to non-affiliated 
reinsurers totaled $138,298,000, $140,928,000, and $131,772,000 in 1997, 
1996, and 1995, respectively.  Insurance is ceded principally to reduce net 
liability on individual risks and to protect against catastrophic losses.  
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.

                                       5

<PAGE>

          During the period 1995 through 1997, certain of the Company's 
reinsurers were unable to meet their obligations to the Company under 
reinsurance treaties. As reserves were previously established for the 
uncollectible amounts, the effects of the insolvent reinsurers on net 
earnings for 1995 through 1997 were immaterial.  The Company continually 
monitors the financial stability of its reinsurers and establishes reserves 
for uncollectible reinsurance balances on a regular basis.  As a result of 
these reviews, the Company reevaluates its position with respect to its 
reinsurance.  During 1995 and 1996, the Company provided $613,296 and 
$1,006,140 for uncollectible reinsurance balances.  During 1997, no 
additional provision was made.  The Company believes that current reserve 
levels for uncollectible reinsurance are sufficient to cover the related 
exposure.

          The Company attempts to purchase reinsurance from a limited number of
financially strong reinsurers.  Retention levels are adjusted each year to
maintain a balance between the growth in surplus and the cost of reinsurance. 
At December 31, 1997, the Company had prepaid reinsurance premiums and
reinsurance recoverables on paid and unpaid losses and settlement expenses with
American Re-Insurance Company (rated A+ "superior" by A.M. Best Company) that
amounted to $67,733,602.  All other reinsurance balances recoverable, when
considered by individual reinsurer, are less than 10% of shareholders' equity.

          The following table sets forth the largest reinsurers in terms of 
amounts recoverable, the total amounts recoverable net of reinsurance 
payables from such reinsurers as of December 31, 1997 and the amounts of 
written premium ceded by the Company to such reinsurers during 1997.

          As of December 31, 1997, the Company held $11,626,930 in irrevocable
letters of credit, $7,282,657 under trust agreements and $1,412,968 in cash to
collateralize a portion of the total amount recoverable.

          Since 1992, the Company has purchased non-proportional contracts.  
This allows the Company to retain a larger percentage of the premium and a 
larger portion of the initial loss risk.  Under non-proportional reinsurance, 
the ceding company retains losses on a risk up to a specified amount and the 
reinsurers assume any losses above that amount.  Since 1989, through its 
various reinsurance programs, the Company has generally limited its maximum 
retained exposure on any one risk to $1,000,000.  The Company seeks to limit 
its net aggregate exposure to a single catastrophic event to less than 10% of 
shareholders' equity by purchasing various types of reinsurance.

          In 1997, the Company's underwriting was supported by up to 
$200,000,000 in traditional reinsurance protection.  In 1998, the Company has 
enhanced this protection by adding an additional $20,000,000 in catastrophe 
reinsurance protection at improved terms and conditions.  Using 
computer-assisted techniques, the Company quantifies and monitors its 
exposure to earthquake risk, the most significant catastrophe exposure to the 
Company.  Detail is captured for each location covered for earthquake risk 
and the Probable Maximum Loss (PML) for each risk is determined.  The PML 
calculation for each risk includes all faults to which the risk is exposed. 
Richter scale magnitudes used in the PML calculations are determined and 
applied separately for each fault.  The Company uses the greater of the 
magnitude of an earthquake which only occurs every 100 years or 6.5 on the 
Richter scale in its PML calculations.  Several widely accepted methods are 
used to estimate the magnitude of the 100 year event for each fault. 
Underwriting decisions are based on the PML as determined by the system, 
which calculates PML's on over 200 faults.  Portfolio runs are made regularly 
to determine the Company's overall exposure on each fault from all risks 
covered.  Total exposure after facultative reinsurance is managed by the 
Company to fall within the limits covered by the Company's chosen net 
retention, working layer treaty reinsurance and catastrophe reinsurance.

          In 1997, the Company continued its innovative catastrophe 
reinsurance and loss financing program with Centre Reinsurance (Centre Re). 
The program, called Catastrophe Equity Puts (CatEPuts)-SM-, augments the 
Company's traditional reinsurance by integrating its loss financing needs 
with a pre-negotiated sale of securities linked to exchange-traded shares. 
CatEPuts allows the Company to put up to $50.0 million of its convertible 
preferred shares to Centre Re at a pre-negotiated rate in the event of a 
catastrophic loss provided the loss does not reduce GAAP equity to less than 
$55.0 million.  CatEPuts is intended to be a three-year program and is 
designed to enable the Company to continue operating after a loss of such 
magnitude that its reinsurance capacity is exhausted.  If the Company 
exercises its option to put preferred shares to Centre Re, then Centre Re, in 
turn, has the option to reinsure certain business written by the Company on a 
prospective basis.

FACTORS AFFECTING SPECIALTY PROPERTY AND CASUALTY PROFITABILITY

          The profitability of the specialty property and casualty insurance 
business is generally subject to many factors, including rate competition, 
the severity and frequency of claims, natural disasters, state regulation of 
premium rates, default of reinsurers, interest rates, general business 
conditions, regulatory measures and court decisions that define and expand 
the extent of coverage and the amount of compensation due for injuries or 
losses.  One of the distinguishing features of the property and casualty 
insurance business is that its product must be priced before the ultimate 
claims costs can be known.  In addition, underwriting profitability has 
tended to fluctuate over cycles of several years' duration.  Insurers 
generally had profitable underwriting results in the late 1970's, substantial 
underwriting losses in the early 1980's and somewhat smaller underwriting 
losses in 1986 and 1987.  During the years 1988 through 1992, underwriting 
losses increased due to increased rate competition and the frequency and 
severity of catastrophic losses, although pre-tax operating income remained 
profitable due to investment income gains.  During 1993 through 1996, the 
industry experienced improvement in underwriting losses.  The trends 
experienced during the late 1980s, however, have continued, and companies 
continue to post underwriting losses but remain profitable through investment 
income gains.  As well, ongoing rate cuts are of concern to financial 
analysts.  For 1997, the industry's statutory combined ratio is estimated to 
be 102.0.  The Company believes that certain other factors affect its ability 
to underwrite specialty lines successfully, including:

          SPECIALIZED UNDERWRITING EXPERTISE.  The Company employs 
experienced professionals in its branch offices.  Each office restricts its 
production and underwriting of business to certain classes of insurance 
reflecting the particular areas of expertise of its key underwriters.  In 
accepting risks, all independent and affiliated underwriters are required to 
comply with risk parameters, retention limits and rates prescribed by the 
Company's home office underwriting group, which reviews submissions and 
periodically audits and monitors underwriting files and reports on losses 
over $100,000.  Compensation of senior underwriters is substantially 
dependent on the profitability of the business for which they are 
responsible.  The loss of any of these professionals could have an adverse 
effect on the Company's underwriting abilities and earnings in these lines.

          The Company's Underwriting Policy limits extension of binding 
authority to independent agents.  The Company's product distribution falls 
into distinct categories, with binding authority following the categorization.

                                       7

<PAGE>

          BROKER BUSINESS.  The largest volume of broker generated premium is 
Commercial Property, General Liability, Commercial Umbrella and Employer's 
Excess Indemnity.  This business is produced through wholesale brokers who 
are not affiliated with the Company.  Only a Company underwriter has the 
authority to bind the Company on such risks.

          INDEPENDENT AGENT BUSINESS.  The Surety Division offers its 
business through a variety of independent agents.  Additionally, the 
Specialty Markets Division writes program business, such as Personal Umbrella 
and the In-Home Business Policy, through independent agents.  Each of these 
programs involves detailed eligibility criteria which are incorporated into 
strict underwriting guidelines.  The programs involve prequalification of 
each risk using the "smart" system accessible by the independent agent.  The 
independent agent cannot bind the risk unless they receive approval through 
the Company's "smart" system.

          UNDERWRITING AGENTS.  The Surety Division has authorized two 
underwriting general agencies to underwrite and bind contract surety business 
on behalf of RLI, primarily in the East and Southeast.  One underwriting 
general agency in San Francisco has been authorized to underwrite commercial 
umbrella business in select Western states.  Another underwriting agent in 
New York has been authorized to underwrite and handle claims for low limit 
deductible buy-backs on program business, primarily in the East.

          These underwriting general agencies receive some compensation 
through contingent profit commission.  Otherwise, producers of business who 
are not Company employees are generally compensated on the basis of direct 
commissions with no provision for any contingent profit commission.  There 
are a few volume incentives for producers handling association business, with 
the increased commission involved being tied to the program's underwriting 
profit.  This represents less than 5% of the business.

          RETENTION LIMITS.  The Company limits its net retention of single 
and aggregate risks through the purchase of reinsurance.  See "Business -- 
Specialty Property and Casualty Insurance Segment -- Reinsurance."  The 
amount of reinsurance available fluctuates according to market conditions.  
Reinsurance arrangements are subject to annual renewal.  Any significant 
reduction in the availability of reinsurance or increase in the cost of 
reinsurance could adversely affect the Company's ability to insure specialty 
property and casualty risks at current levels or to add to the amount thereof.

          CLAIMS ADJUSTMENT ABILITY.  The Company has a professional claims 
management team with proven experience in all areas of multi-line claims 
work. This team supervises and administers all claims and directs all outside 
legal and adjustment specialists.  Whether a claim is being handled by the 
Company's claim specialist or has been assigned to a local attorney or 
adjuster, detailed attention is given to each claim to minimize loss expenses 
while providing for loss payments in a fair and equitable manner.

          EXPENSE CONTROL.  Management continues to review all areas of the 
Company's operations to streamline the organization, emphasizing quality and 
customer service, while minimizing expenses.  These strategies will help to 
contain the growth of future costs.  Maintaining and improving underwriting 
and other key organizational systems continues to be paramount as a means of 
supporting the Company's orderly growth in anticipation of a market rebound, 
as it is the Company's philosophy to retain its talented insurance 
professionals and to build infrastructure in spite of the soft market.  Other 
insurance operating expenses as a percent of gross written premiums for the 
years 1997, 1996, and 1995 were 7%, 6%, and 5%, respectively.

          ENVIRONMENTAL EXPOSURES.  The Company is subject to environmental 
claims and exposures through its commercial umbrella, general liability, and 
discontinued assumed reinsurance lines of business.  Within these lines, the 
Company's environmental exposures include environmental site cleanup, 
asbestos removal, and mass tort liability.  The majority of the exposure is 
in the excess layers of the Company's commercial umbrella and assumed 
reinsurance books of business.

</TABLE>

          Although the Company's environmental exposure is limited as a 
result of entering the liability lines after the industry had already 
recognized it as a problem, Management cannot determine the Company's 
ultimate liability within any reasonable degree of certainty.  This ultimate 
liability is difficult to assess due to evolving legislation on such issues 
as joint and several liability, retroactive liability, and standards of 
cleanup.  Additionally, the Company participates primarily in the excess 
layers, making it even more difficult to assess the ultimate impact.


LOSSES AND SETTLEMENT EXPENSES

          Many years may elapse between the occurrence of an insured loss, 
the reporting of the loss to the insurer and the insurer's payment of that 
loss.  To recognize liabilities for unpaid losses, insurers establish 
reserves, which are balance sheet liabilities. The reserves represent 
estimates of future amounts needed to pay claims and related expenses with 
respect to insured events which have occurred.

          When a claim is reported, the claims department establishes a "case 
reserve" for the estimated amount of the ultimate payment.  The estimate 
reflects the informed judgment of professional claims personnel, based on the 
Company's reserving practices and the experience and knowledge of such 
personnel regarding the nature and value of the specific type of claim.  
Estimates for losses incurred but not yet reported are determined on the 
basis of statistical information, including the Company's past experience.  
The Company does not use discounting (recognition of the time value of money) 
in reporting its estimated reserves for losses and settlement expenses.

          The reserves are closely monitored and reviewed by management, with 
changes reflected as a component of earnings in the current accounting 
period.  For lines of business without sufficiently large numbers of policies 
or that have not accumulated sufficient development statistics, industry 
average development patterns are used.  To the extent that the industry 
average development experience improves or deteriorates, the Company adjusts 
prior accident years' reserves for the change in development patterns.  
Additionally, there may be future adjustments to reserves should the 
Company's actual experience prove to be better or worse than industry 
averages.

                                       9
<PAGE>

          As part of the reserving process, historical data is reviewed and 
consideration is given to the anticipated impact of various factors such as 
legal developments and economic conditions, including the effects of 
inflation. The reserving process provides implicit recognition of the impact 
of inflation and other factors affecting claims payments by taking into 
account changes in historic payment patterns and perceived probable trends.  
Changes in reserves from the prior years' estimates are calculated based on 
experience as of the end of each succeeding year (loss and settlement expense 
development).  The estimate is increased or decreased as more information 
becomes known about the frequency and severity of losses for individual 
years.  A redundancy means the original estimate was higher than the current 
estimate; a deficiency means that the current estimate is higher than the 
original estimate.

          Due to the inherent uncertainty in estimating reserves for losses 
and loss adjustment expenses, there can be no assurance that the ultimate 
liability will not exceed amounts reserved, with a resulting adverse effect 
on the Company.  Based on the current assumptions used in calculating 
reserves, Management believes the Company's overall reserve levels at 
December 31, 1997 are adequate to meet its future obligations.

          The table which follows is a reconciliation of the Company's unpaid 
losses and settlement expenses for the years 1997, 1996, and 1995.

<TABLE>
<S>      <C>
1995      During 1995, the Company experienced approximately $23,300,000 of 
          adverse development on loss reserves.  This development resulted 
          from approximately $27,300,000 of adverse development in the 
          property line due to the 1994 Northridge earthquake.  Excluding the 
          earthquake development, the Company experienced approximately 
          $4,000,000 of favorable development. Approximately $1,000,000 of 
          this favorable development occurred in the property line excluding 
          the earthquake, with the remaining $3,000,000 occurring in the 
          other liability and products liability lines.  The liability 
          development was the result of IBNR reserve decreases made possible 
          by lower than expected tail development on two liability programs.

1996      During 1996, the Company experienced approximately $1,463,000 of 
          favorable development on loss reserves.  This development resulted 
          from approximately $1,519,000 of favorable development in the 
          property lines of business. Various property claims closed during 
          the year were settled below recorded reserves.  The remaining 
          $56,000 of adverse development relates to the net effect of changes 
          made to casualty loss reserves.  This development is a result of 
          reserve strengthening of $3,557,000 made in the General Liability 
          and Miscellaneous Professional business on accident years 1987 
          through 1995.  This increase was offset by favorable development 
          and reserve decreases of $3,501,000 in the Umbrella and Excess 
          Employer's Indemnity programs on accident years 1986 and 1993 
          through 1995.

1997      During 1997, the Company experienced approximately $520,000 of 
          favorable development on loss reserves.  The development results 
          from loss reserve adjustments in various lines of business.  
          Reserve strengthening was necessary on the Property line of 
          business due to development on the Lender's Single Interest 
          program.  As a result, an increase of $1,465,000 was made to IBNR 
          reserves.  This increase, however, was offset by $1,985,000 of 
          favorable development on the Company's other casualty, in-home 
          business, and surety bonding programs.

          The table on the following page presents the development under 
          generally accepted accounting principles of the Company's balance 
          sheet reserves for 1988 through 1997.  The top line of the table 
          shows the reserves at the balance sheet date for each of the 
          indicated periods.  This represents the estimated amount of losses 
          and settlement expenses arising in all prior years that are unpaid 
          at the balance sheet date, including losses that had been incurred 
          but not yet reported to the Company.  The lower portion of the 
          table shows the re-estimated amount of the previously recorded 
          reserves based on experience as of the end of each succeeding year. 
          The estimate changes as more information becomes known about the 
          frequency and severity of claims for individual periods.

OPERATING RATIO

PREMIUMS TO SURPLUS RATIO

          The following table shows, for the periods indicated, the Company's
insurance subsidiaries' statutory ratios of net premiums written to
policyholders' surplus.  While there is no statutory requirement applicable to
the Company which establishes a permissible net premiums written to surplus
ratio, guidelines established by the National Association of Insurance
Commissioners provide that this ratio should generally be no greater 
than 3 to 1.

GAAP AND STATUTORY COMBINED RATIOS

          The underwriting experience of the Company is best indicated by its 
GAAP combined ratio, which is the sum of (a) the ratio of incurred losses and
settlement expenses to net premiums earned (loss ratio) and (b) the ratio of
policy acquisition costs and other operating expenses to net premiums earned
(expense ratio).

          respectively.

          The Company also calculates the statutory combined ratio, which is not
indicative of GAAP underwriting profits due to accounting for multiple-year
retrospectively-rated reinsurance contracts and policy acquisition costs
differently for statutory accounting purposes compared to GAAP.  The statutory
combined ratio is the sum of (a) the ratio of statutory loss and settlement
expenses incurred to statutory net premiums earned (loss ratio) and (b) the
ratio of statutory policy acquisition costs and other underwriting expenses to
statutory net premiums written.

                                     INVESTMENTS

          The investment portfolios of the Company are managed by an Investment
Committee of the Board of Directors.  The Company follows an investment policy
that is reviewed quarterly and revised periodically.

          Investments of the highest quality and marketability are critical for
preserving claims paying ability.  Virtually all of RLI's fixed income
investments are U.S. Government securities or AA rated or better taxable and tax
exempt issues.  Common stock portfolios are limited to securities listed on
national exchanges and listed by the Securities Valuation Office of the National
Association of Insurance Commissioners.  The investment portfolio serves
primarily as the funding source of loss reserves and secondly as a source of
income.  For these reasons, RLI's primary investment criteria are quality and
liquidity, followed by yield.

          During 1997, operating cash flows were used to acquire fixed income 
instruments composed mainly of intermediate-term U.S. Government and Agency 
securities and municipal securities.  Additionally, a small portion of the 
funds were allocated to an investment grade convertible debenture portfolio 
designed to provide diversification and yield enhancement to the portfolio.  
The tax-exempt component of the fixed maturity portfolio increased $25.1 
million, to $139.8 million; and comprises 41.9% of the Company's total fixed 
maturity portfolio, up 4.7% from year end 1996.  The taxable U.S. Government, 
Agency and Municipal portion of the fixed income portfolio declined by $3.3 
million to $182.5 million, or 54.7% of the total versus 60.3% at year end 
1996.  Investment grade corporate securities totaled $4.9 million compared to 
$3.7 million at year end 1996, while convertible debenture securities totaled 
$6.5 million, or 1.9% of the fixed income portfolio.

          Equity securities increased $62.6 million from $188.9 million at 
the end of last year to $251.5 million at the end of 1997.  During 1997, net 
common equity investments totaling $6.9 million were purchased and pretax 
unrealized appreciation of equity securities totaled $55.7 million.  Equity 
securities as a percentage of cash and invested assets increased to 41.6% at 
the end of 1997 from 35.1% at year end 1996.  Combined cash and short-term 
investments totaling $18.7 million at year end 1997 represented 3.1% of cash 
and invested assets versus 7.6% in 1996.  The Company's short-term 
investments consist of U.S. Government and Agency backed money market funds 
and the highest rated commercial paper.

          RLI's mix of fixed income securities continues to be biased in 
favor of U.S. Government and Agency securities due to their high liquidity 
and almost risk-free nature.  The mixture of tax-exempt and taxable 
instruments within the fixed income portfolios is decided at the time of 
purchase on the basis of available after-tax returns and overall taxability 
of all invested assets.  The majority of securities reviewed for purchase are 
either U.S. Government, Agency, or high grade municipal debt instruments.  As 
part of its investment philosophy, the Company attempts to avoid exposure to 
default risk by holding, almost exclusively, instruments ranked in the top 
two grades of investment security quality by Standard & Poor's and Moody's 
(i.e. AAA and AA).  Interest rate risk is limited by restricting and managing 
acceptable call provisions among new security purchases.

                                          14

          The Company follows a program of matching assets to anticipated 
liabilities to ensure its ability to hold securities until maturity.  The 
Company's known debt and long-term accounts payable are added to the estimate 
of its unpaid losses and settlement expenses, by line of business.  These 
anticipated liabilities are then factored against ultimate payout patterns 
and the resulting payout streams are fully funded with the purchase of 
fixed-income securities of like maturity.  Management believes that interest 
rate risk can best be minimized by such asset/liability matching.

          Aggregate maturities for the fixed maturity securities are as follows:

</TABLE>


          Under generally accepted accounting principles, equity and fixed 
income securities are carried at fair market value, except that a company 
that can demonstrate its ability to hold fixed income securities until their 
originally scheduled maturity is permitted to carry such securities at 
amortized cost.  RLI Corp. has chosen to carry most of its fixed income 
securities at amortized cost as it believes it has constructed its fixed 
income portfolios to match expected liability payouts and thus has the 
ability and intention to hold such securities until originally scheduled 
maturity.  Consequently, fluctuations in the market value of most bonds are 
not reflected in the financial statements and do not affect shareholders' 
equity.  At December 31, 1997, the Company's equity securities valued at 
$251.5 million, accounted for 41.6% of total cash and invested assets and 
94.7% of the combined statutory surplus of its insurance subsidiaries.  At 
December 31, 1997, net pretax unrealized capital appreciation of equity 
securities was $132.8 million.

                                      REGULATION

     STATE REGULATION

     The Company's insurance subsidiaries are highly regulated by insurance 
regulators in their states of incorporation as well as the states in which 
they do business.  Such regulations, among other things, limit the amount of 
dividends and other distributions the subsidiaries can pay without prior 
approval of the insurance department in the states in which they are 
physically and/or commercially domiciled, and impose restrictions on the 
amount and type of investments they may have.  Certain states also regulate 
the rates insurers may charge for certain property/casualty products.

     These regulations are designed to ensure financial solvency of insurance 
companies and to require fair and adequate service and treatment for 
policyholders.  They are enforced through the granting and revoking of 
licenses to do business, licensing of agents and brokers, monitoring of trade 
practices, policy form approval, fair and equitable premium and commission 
rates, and minimum reserve and capital requirements.  The procedures are 
administered by the various state departments of insurance and are 
supplemented by periodic reporting procedures and periodic examinations.

     The quarterly and annual financial reports to the states utilize 
accounting principles which are different than the generally accepted 
accounting principles used in shareholders' reports.  The statutory 
accounting principles, in keeping with the intent to assure policyholder 
protection, are based, in general, on a liquidation concept while generally 
accepted accounting principles are based on a going concern concept.  
Currently, the National Association of Insurance Commissioners (NAIC) has a 
project to codify statutory accounting practices, the result of which is 
expected to constitute the only source of "prescribed" statutory accounting 
practices.  Accordingly, the project may result in changes to the accounting 
policies that insurance enterprises use to prepare their statutory financial 
statements.

     Under the laws of most states , regulatory authorities have relatively 
broad discretion with respect to granting, renewing and revoking brokers' and 
agents' licenses to transact business in the state.  The manner of operating 
in particular states may vary according to the licensing requirements of the 
particular state, which may, among other things, require a firm operate in 
the state through a corporation.  In a few states, licenses are issued only 
to individual residents or locally-owned business entities.  In such cases, 
the Company has arrangements with residents or business entities licensed to 
act in the state.


                                          16
<PAGE>

     As an insurance holding company, RLI Corp. is subject to regulation by 
the states in which its insurance subsidiaries are domiciled or transact 
business. Most states have enacted legislation that requires each insurance 
company in a holding company system to register with the insurance regulatory 
authority of its state of domicile and furnish to it financial and other 
information concerning the operations of companies within the holding company 
system that may materially affect the operations, management or financial 
condition of the insurers within the system.  All transactions within a 
holding company system affecting insurers must be fair, and the insurer's 
policyholder surplus following any transaction must be both reasonable in 
relation to its outstanding liabilities and adequate for its needs.  Notice 
to applicable regulators is required prior to the consummation of certain 
transactions affecting insurance subsidiaries of the holding company system.

     PROPOSITION 103 (RATE ROLLBACK INITIATIVE)--In November 1988, California 
voters approved Proposition 103, which requires insurance rates for certain 
lines of business to be rolled back 20% from the rates in effect in November 
1987.  Beginning in 1989 and ending in 1994, the Company deferred premium 
revenue of $1,449,200 and accrued interest in the amount of $1,050,480 to 
cover the proposed rollback.  No additional provision was made during 1995 
and the total funds accrued for rollback remained $2,449,680 at December 31, 
1995.

During 1996, the Company reached a settlement with the California Department of
Insurance resolving its total liability for refunds and interest under
Proposition 103.  The settlement requires the Company to pay $2,987,050 in
refunds and interest.  In the second quarter of 1996, the Company recorded a
pretax charge of $487,370 to record the difference between the actual settlement
and the amount previously accrued.  During 1997, the Company issued refund
checks to policyholders.  As of December 31, 1997, the total unclaimed refund
amount was $1,526,283.  Any amounts unclaimed as of November 1, 1998 will
escheat to the California Division of Unclaimed Property.


     ASSESSMENTS AGAINST INSURERS

     Under insurance insolvency or guaranty laws in most states in which the 
Company operates, insurers doing business therein can be assessed for 
policyholder losses covered by insolvent insurance companies.  The amount and 
timing of any future assessments on the Company under these laws cannot be 
reasonably estimated and are beyond the control of the Company.  Recent 
financial difficulties of insurance companies increase the probability of 
assessments under these laws.  Most of these laws do provide, however, that 
an assessment may be excused or deferred if it would threaten an insurer's 
financial strength.  The Company generally accrues the full amount of the 
assessment upon notification.

     LEGISLATION AT FEDERAL LEVEL

     Although the federal government generally does not directly regulate the 
insurance business, federal initiatives often have an impact on the business 
in a variety of ways.  Current and proposed federal measures which may 
significantly affect the insurance business include employee benefits 
regulation, limitation on anti-trust immunity, minimum solvency requirements 
and removal of barriers preventing banks from engaging in the insurance 
business. The Company is monitoring the following federal proposals:

     NATURAL DISASTER ACT--Recent natural disasters such as Hurricane Andrew, 
the Midwestern floods and the Northridge Earthquake have sparked debate on 
the best way to provide affordable insurance coverage for such events.  
Previously the Company supported the proposed Natural Disaster Act as the 
most desirable alternative.  A new congressional bill, "The Homeowners 
Insurance Availability Act of 1997" addresses issues of catastrophe insurance 
for homeowners through federal assistance to state guarantee funds.  The 
Company is monitoring the bill's progress and has neither opposed nor 
supported the bill at this time.

     SUPERFUND REFORM (ENVIRONMENTAL LIABILITY)--The Comprehensive 
Environmental Response, Compensation and Liability Act ("CERCLA"), more 
commonly known as Superfund, remains in effect, but no reform legislation was 
passed in 1997. Insurance companies, other businesses, environmental groups 
and municipalities are advocating a variety of reform proposals to revise the 
cleanup and liability provisions of CERCLA.  Any reform proposal could result 
in additional taxation to fund cleanup efforts.


                                          17
<PAGE>

     NATIONAL ASSOCIATION OF INSURANCE COMMISSIONERS

     The National Association of Insurance Commissioners (NAIC) facilitates 
the regulation of multi-state companies through uniform reporting 
requirements, standardized procedures for financial examinations, and uniform 
regulatory procedures embodied in model acts and regulations.  Current 
developments address the reporting and regulation of the adequacy of capital 
and surplus.  

     The NAIC has developed Property-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 
asset (investment and credit) risk and underwriting (loss reserves, premiums 
written, and unearned premium) risk.  The NAIC model law calls for various 
levels of regulatory action based on the magnitude of an indicated RBC 
capital deficiency, if any.  The Company continues to monitor its 
subsidiaries' internal capital requirements and the NAIC's RBC developments.  
The Company has determined that its capital levels are well in excess of the 
minimum capital requirements for all RBC action levels.  Management believes 
that its capital levels are sufficient to support the level of risk inherent 
in its operations.

                                 CORPORATE COMPLIANCE

     The Company has developed a Code of Conduct and Compliance Manual which 
provides employees with guidance on complying with a variety of federal and 
state laws.

                            AGENCY LICENSES AND TRADEMARKS

     Replacement Lens Inc. or its designated employees, must be licensed to 
act as resident or non-resident brokers or agents by regulatory authorities 
in the states  in which it operates.

     Replacement Lens Inc. obtained service mark registration of the letters 
"RLI" in 1978 and currently maintains such registration in 47 states.  Such 
registration protects the mark from deceptively similar use by the Company's 
competitors.  The duration of this registration is ten years for all states 
except three in which registration is limited to five years unless renewed. 
Duration of the registration in the State of Wisconsin is twenty years.

                                      CLIENTELE

     No significant part of the Company's or its subsidiaries' business is 
dependent upon a single client or upon a very few clients, the loss of any 
one of which would have a material adverse effect on the Company.

                                      EMPLOYEES   

     The Company employs a total of 392 associates.  Of the 392 total 
associates, 35 are part-time and 357 are full-time.

(d)  Financial Information about Foreign and Domestic Operations and Export 
     Sales.

     For purposes of this discussion, foreign operations are not considered 
material to the Company's overall operations.

Item 2.  PROPERTIES

     The Company owns a two-story, 80,000 square foot building in Peoria, 
Illinois, which serves as the Corporate Headquarters for RLI Corp., RLI 
Insurance Company and Mt. Hawley Insurance Company.  Two RLI Insurance 
Company Branch Offices also lease office space in this building.

     Located on the same 15.0 acre campus is a 12,800 square foot building. 
Nearly 9,800 square feet of this building are used as warehouse storage for 
records and equipment.  The remaining 3,000 square feet is used as office 
space.

     Additionally, the Company owns two other buildings located near the 
headquarter building.  One, a 19,000 square foot building, is leased to Maui 
Jim, Inc. and is used as their headquarters.  The other, a 20,000 square foot 
building, was purchased in December of 1996.  Currently, used for warehousing 
and record storage, this building will provide space for future office 
expansion.

     All other operations of RLI Corp. lease the office space which they need 
in various locations throughout the country.

Item 3.  LEGAL PROCEEDINGS

     The Company is involved in certain legal proceedings and disputes 
considered by management to be ordinary and incidental to the business or 
which have no foundation in fact.  Management believes that valid defenses 
exist as to all such litigation and disputes, and is of the opinion that 
these will not have a material effect on the Company's consolidated financial 
statements.

Item 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     No matters were submitted by the Company to a vote of security holders 
during the fourth quarter of the fiscal year covered by this report.

the related consolidated statements of earnings and comprehensive earnings, 
shareholders' equity, and cash flows for each of the years in the three-year 
period ended December 31, 1997, as contained in the 1997 annual report to 
shareholders. These consolidated financial statements and our report thereon 
are incorporated by reference in the annual report on Form 10-K for the year 
1997.  In connection with our audits of the aforementioned consolidated 
financial statements, we also have audited the related financial statement

MANAGEMENT'S DISCUSSION AND ANALYSIS

OVERVIEW

RLI Corp. (the Company) is a holding company that underwrites selected 
property and casualty insurance through its major subsidiaries collectively 
known as RLI Insurance Group (the Group). The Group has accounted for 
approximately 84% of consolidated revenue over the last two years by 
providing property and casualty coverages primarily for commercial risks. As 
a niche insurer, the Group offers products geared to the needs of those 
insureds generally overlooked by traditional insurance markets.

The property and casualty insurance business is cyclical and influenced by 
many factors, including price competition, economic conditions, natural 
disasters, interest rates, state regulations, court decisions, and changes in 
the law. One of the unique and challenging features of the property and 
casualty insurance business is that products must be priced before costs are 
fully known, because premiums are charged before claims are incurred.

Property insurance results are subject to the variability introduced by 
natural and man-made disasters such as earthquakes, fires and hurricanes. The 
Company's major catastrophe exposure is to losses caused by earthquakes, 
since over 60% of the Company's 1997 total property premiums were written in 
California. The Company limits its net aggregate exposure to a catastrophic 
event by purchasing reinsurance and through extensive use of 
computer-assisted modeling techniques. These techniques provide estimates of 
the concentration of risks exposed to catastrophic events. Utilizing this 
approach, the Company attempts to limit its net aggregate exposure to a 
single catastrophic event to less than 10% of total shareholders' equity. 
During 1996, the Company entered into an innovative financing arrangement, 
known as Catastrophe Equity Puts, which provides for the issuance of the 
Company's convertible preferred shares at a pre-negotiated rate to restore up 
to $50 million in surplus.

The casualty portion of the Company's business consists largely of commercial 
and personal umbrella, general liability, and contract and miscellaneous 
surety bond coverages. In addition, the Group provides directors & officers 
liability, employers' indemnity, and in-home business owners coverage. The 
casualty book of business is subject to the risk of accurately estimating 
losses and related loss reserves since the ultimate settlement of a casualty 
claim may take several years to fully develop. The casualty line may also be 
affected by evolving legislation and court decisions that define the extent 
of coverage and the amount of compensation due for injuries or losses.

The surety division of RLI specializes in writing small- and medium-sized 
commercial and contract surety products. The commercial surety products 
usually involve a statutory requirement for bonds placed by governmental 
entities or the court system. This industry has historically maintained a 
relatively low loss ratio. Losses may fluctuate, however, due to adverse 
economic conditions that may affect the financial viability of an insured.

The contract surety market guarantees the construction work of a commercial 
contractor for a specific project. As such, this line has historically 
produced marginally higher loss ratios than the commercial surety line. 
Generally, losses occur due to adverse economic conditions, inclement weather 
conditions, or the deteriorated financial condition of the contractor.

The consolidated financial statements and related notes found on pages 30-49 
should be read in conjunction with the following discussion.

YEAR ENDED DECEMBER 31, 1997, COMPARED
TO YEAR ENDED DECEMBER 31, 1996

Consolidated gross sales--which consist of gross premiums written, net 
investment income and realized investment gains (losses)--totaled $306.4 
million, a 1.6% increase from 1996. Consolidated revenue for 1997 was $169.4 
million, up 9.1% from the previous year. The increase in revenue was 
attributable in part to increased realized investment gains of nearly $3.0 
million, compared to $1.0 million in 1996. Also, an 8.6% increase in net 
earned premiums reflected the addition of the Hawaii Residential Insurance 
program at a higher net retention than many of the Company's other lines.

During the fourth quarter of 1996, the Company introduced the reporting of 
comprehensive earnings in public releases of financial information. The 
Company has elected for early adoption of Financial Accounting Standards 
Board Statement 130 which requires this disclosure. Comprehensive earnings 
include not only traditional net income but other sources of equity growth as 
well. The material adjustment applicable to the Company's net earnings is the 
inclusion of net unrealized gains and losses, after tax.

As this chart indicates, comprehensive earnings per share for the last five 
years exceed reported net earnings by 95% on a diluted basis. As a result, 
shareholders' equity reached an unprecedented level of nearly $267.0 million, 
up over 33% from 1996.

A line chart that depicts cumulative diluted comprehensive earnings on one 
line and cumulative diluted net earnings on a second line for the years ended 
1993 through 1997 has been excluded from this electronic filing.  The chart, 
labeled the true measure of our value--cumulative comprehensive earnings vs. 
net earnings, plots the cumulative per share values from the above five-year 
table and concludes with the statement--over the past five years, cumulative 
after-tax comprehensive earnings have accounted for 95.0% more of RLI's 
increased value than after-tax net earnings.

RLI INSURANCE GROUP

Gross written premiums in 1997 were $278.8 million, compared to $276.8 
million in 1996. This modest increase reflected the Company's firm commitment 
to sound underwriting practices during this period of unusually arduous 
pricing and market conditions. The Group's pretax underwriting earnings for 
1997 were $18.8 million, a 14.6% increase over the $16.4 million reported in 
1996 as a result of this focus on underwriting profit.

The Company's property segment gross written premiums were basically flat in 
1997 at $139.5 million, compared to $138.1 million in 1996. There were, 
however, significant changes in the product mix of this segment. While 
existing product gross premiums were down due to rate reductions and 
increased competitor capacity, the reductions in net written premiums were 
mitigated through better use of reinsurance. Fire and difference in 
conditions (earthquake) gross written premiums were down 16% and 12% 
respectively from 1996, compared to declines in net written premiums of only 
3% and 7%. Meanwhile, the Group bolstered its overall premium production in 
this segment with the addition of the Hawaii Residential Insurance program. 
Including the assumption of $10.8 million of unearned premium upon 
acquisition, gross and net premiums written for this program were $19.5 
million and $19.1 million, respectively, for the year ended 1997.

The property segment contributed the largest share of the Group's pretax 
profits, increasing to $21.4 million in 1997, compared to $18.8 million in 
1996. These results were reflected in the property segment GAAP combined 
ratio of 65.5 for 1997. The combined ratio increase from 60.9 in 1996 
reflected the incremental acquisition costs associated with the assumption of 
Hawaiian homeowner in-force business from the Hawaii Property Insurance 
Association. Such costs will not be associated with the continued production 
of these premiums in 1998. These increased expenses were offset by a lower 
property segment loss ratio of 19.2 in 1997, compared to 22.4 in the previous 
year.

Casualty gross written premiums declined 10.7% from 1996, to $113.5 million 
in 1997. Much of this decline was due to discontinuing certain production 
source relationships in the general liability area as a result of prolonged 
declines in profitability. Despite premium declines, the casualty segment 
GAAP combined ratio was 104.6 for 1997. While lower premiums have negatively 
influenced the

                                      23

<PAGE>

expense ratio component of this indicator, the loss ratio for 1997 was 68.5, 
compared to 72.1 in 1996. Even at this level, management believes that loss 
reserves for this segment will be adequate and that the investment income 
derived from these reserved funds will provide significant future earnings 
potential. Such optimism is additionally warranted by the favorable total 
reserve development in 1997 on prior accident years' reserves, as indicated 
in note 6 of the financial statements.

The surety segment provided the most notable premium growth among existing 
products, increasing to $25.8 million, a 123% increase over the $11.6 million 
for the prior year. Much of this growth was achieved specifically through the 
increased writing of contract bonds, which added $12.5 million of additional 
premium in 1997. The surety segment profit picture also improved dramatically 
as pretax underwriting profits came in at $526,000, compared to an 
underwriting loss of $406,000 in 1996. This was largely the result of the 
anticipated payoff in premium writings from production investments made over 
the last several years. The combined ratio for this segment fell to 95.4 in 
1997 from 109.2 in 1996, mostly from the expense ratio improvement of 8.8 
points.

INVESTMENT INCOME

Net dividend and interest income increased 3.7% during 1997, due to growth in 
invested assets. The Company realized $3.0 million in capital gains in 1997, 
compared to $1.0 million in 1996. Operating cash flows were $35.0 million in 
1997, compared to $48.9 million in 1996. All cash flows in excess of current 
needs were used to fund our common stock repurchase program, purchase equity 
securities, and acquire fixed-income instruments composed of intermediate 
term, high grade tax-exempt securities, convertible debenture securities, and 
U.S. government and agency securities.

The yields on the Company's fixed-income investments for the years ended 
December 31, 1997 and 1996, respectively, were as follows:

    Tax-exempt           5.00%    4.97%

</TABLE>

Yields for 1997 rose during the first half of the year and remained fairly 
stable throughout the third quarter. A significant bond price rally during 
the fourth quarter brought yields in the Treasury market close to their 
historic lows. Tax-exempt yields were up slightly as the Company extended its 
portfolio duration to gain additional yield and minimize the effect of 
declining interest rates. The taxable segment of the portfolio remained 
fairly stable during the year with the overall yield unchanged.

The investment results of the Company for the last five years are shown in 
the following table.

The annualized return for 1997 was again enhanced by the strong performance 
of our equity portfolio, which contributed unrealized appreciation of $55.7 
million to the 33.9% of the portfolio's total return.

INTEREST AND GENERAL CORPORATE EXPENSE

Interest expense on debt was $1.5 million in 1997, down 44.9% from $2.8 
million in 1996. This decline was the direct result of the Company's call for 
redemption and subsequent conversion of all of its outstanding convertible 
debentures during July, 1997. General corporate expenses increased 27.3% in 
1997, as a result of accrued executive bonuses relating to the MVP program 
and recognition of the expense of issuing directors' stock options.

INCOME TAXES

The Company's effective tax rates for 1997 and 1996 were 27.3% and 27.1%, 
respectively. Effective rates are dependent upon components of pretax 
earnings and the related tax effects. The Company's pretax earnings include 
$9.1 million of investment income in 1997 that is wholly or partially exempt 
from federal income tax, compared to $8.0 million in 1996.

OUTLOOK FOR 1998

In 1998, the Company will continue to pursue opportunities for top line 
growth. There is an ongoing process of evaluating various avenues for growth 
such as the acquisition of underwriting talent in certain product lines, 
strategic alliances with producers on existing products, or through 
acquisition. The particular materiality or viability of any future new 
ventures or products is not

                                       24
<PAGE>


known at this time. Specific details regarding events in the Group's various
business segments follows.

PROPERTY INSURANCE

The Company expects further softening of earthquake rates during 1998. 
Exposure will remain constant while reduced reinsurance costs will serve to 
mitigate the bottom line impact of lost premiums.

The Company's fire book of business was affected in 1997 by the loss of the 
product vice president in this line. While this caused a temporary loss of 
momentum, new leadership has been established to provide growth with the 
potential for adding limited international exposures.

The following information appeared as an inset on the top right-hand corner 
of this annual report page: RLI Fact--Regulating our catastrophe 
exposure--Every month, we use our catastrophe modeling system to simulate 
events against our earthquake exposures.  We proactively monitor hundreds of 
fault lines, helping us control our probable maximum loss to any one event.

CASUALTY AND OTHER LINES 

Several initiatives took place late in 1997 to combat the loss of casualty 
premiums to some of the questionable pricing trends seen in 1996. Offices for 
writing both general liability business and commercial umbrella were opened 
in Dallas and Los Angeles.

During November of 1997, the Company entered the transportation business by 
opening an office in Atlanta, which began writing business in 1998. This 
office is staffed by underwriters with extensive experience in the areas of 
truck, public transportation and commercial auto fleet insurance coverages.

SURETY

Gross written premiums are expected to continue to increase, although not quite
at the pace of last year's growth. Increased revenues should continue to drive
down the expense ratio during 1998.

CAPITAL MANAGEMENT

In February, the Company completed a $10 million common stock repurchase 
program. After the conversion of the $46 million debenture issue in July, the 
Company implemented an additional 1.8 million share repurchase program. As of 
December 31, this program was more than 42% completed, with 767,151 shares 
repurchased at a total cost of $32.7 million. Based on the price of RLI stock 
and the availability of both funds and shares, it is anticipated that the 
repurchase program will continue into 1998.

The repurchase program has been funded by the use of available short-term 
borrowing facilities, reverse repurchase agreements and operating cash flows. 
It is anticipated that future repurchases will be funded primarily by 
short-term debt facilities.

As the availability of shares to repurchase and the accumulated level of 
short-term debt warrant, it is possible that the Company may issue a 
longer-term debt facility, thereby repaying short-term debt. Such an issuance 
will depend upon many factors, including the Company's need for funds and the 
prevailing conditions in the capital markets.


YEAR ENDED DECEMBER 31, 1996,
COMPARED TO YEAR ENDED DECEMBER 31, 1995

Consolidated gross sales--which consist of gross premiums written, net 
investment income and realized investment gains--totaled $301.5 million, a 
2.6% increase from 1995. Consolidated revenue for 1996 was $155.4 million, 
down 0.4% from the previous year. The decline in revenue was attributable to 
lower earned premiums of $130.7 million in 1996, compared to $133.5 million 
in 1995. This decrease resulted from the 1995 discontinuation of certain 
lines of business as well as the re-underwriting of the property book of 
business. As written premiums increased during the year, net earned premiums 
grew 4.0% in the fourth quarter of 1996 compared to 1995.

The impact in 1995 from the adverse development of Northridge Earthquake 
claims was a loss of $18.6 million ($1.93 per share).

RLI INSURANCE GROUP

Gross written premiums of $276.8 million were higher than 1995 by 2.0% in 
total, while gross written premiums from continuing programs rose 4.9%. These 
modest increases reflect the Company's focus on underwriting selection even 
during periods of trying market conditions. The Group's pretax earnings for 
1996 were $16.4 million, compared to a loss of $9.9 million in 1995 that was 
impacted by the strengthening of the Northridge Earthquake reserves.

The Company's property book of business produced the most growth, with gross 
written premiums of $138.1 million for the year ended 1996, reflecting an 
8.8% improvement over the same period in 1995. The property line also 
exhibited considerable profitability by achieving a GAAP combined ratio of 
60.9 in 1996, compared to 63.8 in 1995, excluding the impact of the 
Northridge Earthquake. The property GAAP expense ratio for 1996 was 38.5, 
compared to 43.1 in 1995. This decline was the result of property reinsurance 
profit-sharing commissions earned due to favorable loss experience over the 
past year.

Casualty gross written premiums declined 4.0% from 1995, to $138.7 million in 
1996. Much of this decline was due to the discontinued aviation product line, 
where $6.3 million was written in 1995. Other casualty lines were flat or 
slightly down in 1996 from 1995, reflecting the Company's commitment to risk 
selection even during protracted periods of soft market conditions. The 
exception was in the surety product line, where 1996 gross written premiums 
were $11.6 million, compared to $3.7 million in 1995. Reserve strengthening 
on the Company's primary general liability line in 1996 affected casualty 
business profitability as the GAAP combined ratio rose to 103.0, compared to 
99.7 in 1995. Despite this strengthening, total reserve development in 1996 
on prior accident years' reserves was favorable, as indicated in note 6 to 
the financial statements.

INVESTMENT INCOME

Net dividend and interest income increased 7.5% during 1996. The increase was 
due to the growth in invested assets throughout 1996 and substantial cash 
flow provided from recoveries from our reinsurers. The Company realized $1.0 
million in capital gains in 1996, compared to $457,000 in 1995. Operating 
cash flows were up substantially for 1996, increasing to $48.9 million from 
$24.6 million in 1995. All cash flows in excess of current needs were used to 
reduce outstanding short-term debt, fund our stock repurchase program, 
purchase equity securities, and acquire fixed-income instruments composed of 
intermediate term, high grade tax-exempt securities, convertible debenture 
securities and U.S. government and agency securities. During 1996, $2.8 
million in short-term debt was paid off, and the Company began a $10 million 
stock repurchase program. By year end, the Company had repurchased 116,212 
shares of stock at a total cost of $3.0 million.

The yields on the Company's fixed-income investments for the years ended 
December 31, 1996 and 1995, respectively, were as follows:

<TABLE>

                              1996       1995

            Tax-exempt       4.97%      5.06%
</TABLE>

Yields for 1996 remained relatively stable as a roller coaster bond market 
saw yields rise significantly by midyear and then return to levels slightly 
above those at year end 1995. Tax-exempt yields were down slightly as 
substantially higher yielding securities matured or were called during the 
year and were reinvested at the lower current levels. The taxable segment of 
the portfolio saw a slight increase in yield through the inclusion of 
callable agencies and an extension of the overall portfolio duration.

INTEREST AND GENERAL CORPORATE EXPENSE

Interest expense on debt was $2.8 million in 1996, down 16.1% from 1995. This 
decline reflected the refinancing of an Industrial Revenue Bond with 
short-term debt at a considerably lower interest rate at the end of 1995. The 
short-term debt was subsequently paid off during the first quarter of 1996. 
General corporate expenses increased 56.6% in 1996, primarily as a result of 
accrued executive bonuses relating to the MVP program.

INCOME TAXES

The Company's effective tax rate in 1996 was 27.1% on pretax earnings of 
$35.2 million. These earnings include $8.0 million of investment income that 
is wholly or partially exempt from federal income tax. In 1995, the Company 
reported a tax benefit of $124,000 on pretax earnings of $7.8 million. 
Nontaxable income for 1995 was $7.4 million.


ACCOUNTING STANDARDS

In February 1997, the Financial Accounting Standards Board (FASB) issued 
Statement No.128, "Earnings Per Share" (Statement 128). Statement 128 
supersedes APB Opinion No. 15, "Earnings Per Share" (APB 15), and specifies 
the computation, presentation, and disclosure requirements for earnings per 
share (EPS) for entities with publicly held common stock or potential common 
stock. Statement 128 was issued to simplify the computation of EPS and to 
make the U.S. standard more compatible with the EPS standards of other 
countries. Statement 128 replaces the presentation of primary EPS with a 
presentation of basic EPS and fully diluted EPS with diluted EPS. Basic EPS, 
unlike primary EPS, excludes dilution and is computed by dividing income 
available to common stockholders by the weighted-average number of common 
shares outstanding for the period. Diluted EPS


                                       26


<PAGE>


reflect the dilution that could occur if securities or other contracts to issue
common stock were exercised or converted into common stock or resulted in the
issuance of common stock that then shares in the earnings of the entity. Diluted
EPS is computed similarly to fully diluted EPS under APB 15.

Statement 128 is effective for financial statements for both interim and 
annual periods ending after December 15, 1997. The Company adopted this 
statement during the fourth quarter of 1997. All prior period EPS data 
presented has been restated to conform to Statement 128.

In June 1997, the FASB issued Statement No. 130, "Reporting Comprehensive 
Income" (Statement 130), which established standards for the reporting and 
display of comprehensive income and its components in a full set of general 
purpose financial statements. Under Statement 130, comprehensive income is 
divided into net income and other comprehensive income. This Statement does 
not change or modify the reporting or display of net income, but does provide 
a basis for classification and display of other comprehensive income. Items 
representing comprehensive income include foreign currency translation items, 
minimum pension liability adjustments and unrealized gains and losses on 
certain investments in debt and equity securities. Currently, the Company's 
only component of other comprehensive income comes from unrealized gains and 
losses on its available-for-sale debt and equity portfolio.

Statement 130 becomes effective for interim and annual periods beginning 
after December 15, 1997. In the fourth quarter of 1997, the Company elected 
for early adoption of this Statement. As such, comparative financial 
statements provided have been reclassified to reflect the application of the 
provisions of this Statement.

In June 1997, the FASB also issued Statement No. 131, "Disclosures about 
Segments of an Enterprise and Related Information" (Statement 131). Statement 
131 establishes standards for the way that public business enterprises report 
information about operating segments in annual financial statements and 
requires that those enterprises report selected information about operating 
segments in interim financial reports issued to shareholders. It also 
establishes standards for related disclosures about products and services, 
geographic areas, and major customers. This Statement is effective for fiscal 
periods beginning after December 15, 1997. The Company is currently 
evaluating this recently issued Statement.


LEGISLATION

NATURAL DISASTER ACT--Recent natural disasters such as Hurricane Andrew, the 
Midwestern floods and the Northridge Earthquake have sparked debate on the 
best way to provide affordable insurance coverage for such events. 
Previously, the Company supported the proposed Natural Disaster Act as the 
most desirable alternative. A new congressional bill, "The Homeowners 
Insurance Availability Act of 1997," addresses issues of catastrophe 
insurance for homeowners through federal assistance to state guarantee funds. 
The Company is monitoring the bill's progress and has neither opposed nor 
supported the bill at this time.

SUPERFUND REFORM (ENVIRONMENTAL LIABILITY)--The Comprehensive Environmental 
Response, Compensation and Liability Act (CERCLA), more commonly known as 
Superfund, remains in effect, but no reform legislation was passed in 1997. 
Insurance companies, other businesses, environmental groups and 
municipalities are advocating a variety of reform proposals to revise the 
cleanup and liability provisions of CERCLA. Any reform proposal could result 
in additional taxation to fund cleanup efforts.

PROPOSITION 103 (RATE ROLLBACK INITIATIVE)--In November 1988, California 
voters approved Proposition 103, which requires insurance premium rates for 
certain lines of business to be rolled back twenty percent (20%) from the 
rates in effect in November 1987. During the second quarter of 1996, the 
Company reached a settlement with the California Department of Insurance 
resolving its total liability for refunds and interest under Proposition 103. 
The settlement required the Company to return $2,987,050 in premiums and 
interest, which resulted in a 1996 pretax charge of $487,370 to recognize the 
difference between the actual settlement and the amount previously accrued. 
During 1997, the Company issued refund checks to policyholders. As of 
December 31, 1997, the total unclaimed refund amount was $1.5 million. Any 
amounts unclaimed as of November 1, 1998, will escheat to the California 
Division of Unclaimed Property.


LIQUIDITY AND CAPITAL RESOURCES

Historically, the primary sources of the Company's liquidity have been funds 
generated from insurance premiums (operating activities), investment income 
and maturing investments (investment activities). In addition, the Company 
has occasionally received funds from financing activities, such as the sale 
of company treasury stock to the Employee Stock Ownership Plan; issuance of 
common stock or convertible debentures; and short-term borrowings.

The Company maintains two sources of credit from one financial institution: 
one $30.0 million secured line of credit that cannot be canceled during its 
annual term, and one $3.0 million secured line of credit for obtaining 
letters of credit. At December 31, 1997, the Company had $10.0 million in 
outstanding short-term debt. Additionally, the Company was party to two 
reverse repurchase transactions, totaling $14.9 million. All funds were 
utilized to fund the


                                       27


<PAGE>


Company's stock repurchase program. Management believes that cash generated from
operations, investments, and cash available from financing activities will
provide sufficient liquidity to meet the Company's anticipated needs over the
next 12 to 24 months.

In 1996, the Company entered into an innovative catastrophe reinsurance and 
loss financing agreement with Centre Reinsurance (Centre Re). The agreement, 
called Catastrophe Equity Puts (CatEPuts)-SM-, augments the Company's 
traditional reinsurance programs by integrating its loss financing needs with 
a pre-negotiated sale of securities linked to exchange-traded shares. 
CatEPuts allows the Company to put up to $50.0 million of its convertible 
preferred shares to Centre Re at a pre-negotiated rate in the event of a 
catastrophic loss, provided the loss does not reduce GAAP equity to less than 
$55.0 million. CatEPuts is intended to be a three-year program and is 
designed to enable the Company to continue operating after a loss of such 
magnitude that its reinsurance capacity is exhausted. If the Company 
exercises its option to put preferred shares to Centre Re, then Centre Re, in 
turn, has the option to reinsure certain business written by the Company on a 
prospective basis.

During 1997, the Company generated net operating cash flows of $35.0 million, 
up from 1996's $48.9 million. Financing activities included the conversion of 
our $46 million convertible debenture into 1,769,199 shares of RLI Corp. 
common stock, borrowings of $10.0 million from our line of credit, and $14.9 
million in reverse repurchase agreements. All borrowings, as well as a 
portion of operational cash flows, were utilized to repurchase shares of the 
Company's stock. During 1997, 963,700 shares were repurchased at a total cost 
of $39.7 million. The remainder of excess operating cash flows were added to 
the Company's investment portfolio. 

The Company's fixed-income portfolio continues to be biased in favor of U.S. 
government and agency securities due to their highly liquid and almost 
risk-free nature. As part of its investment strategy, the Company attempts to 
avoid exposure to default risk by holding, almost exclusively, securities 
ranked in the top two grades of investment quality by Standard & Poor's and 
Moody's (i.e., AAA or AA). Virtually all of the Company's fixed-income 
portfolio consists of securities rated A or better, with 98% rated AA or 
better. Currently, the majority of the Company's fixed-income portfolio is 
noncallable. Those securities containing call features have been factored 
into the overall duration objectives of the portfolio and will not affect 
efforts to match assets with anticipated liabilities.

A pie chart depicting the Company's investment portfolio split between common 
stock and fixed maturities has been omitted from this electronic filing.  The 
chart shows common stock (large cap, high dividend yield, value stocks) make 
up $251.5 million of the Company's investment portfolio.  The balance of the 
portfolio, $352.4 million, is labeled as fixed maturities and footnoted as 
being $193.9 million taxable securities, $139.8 million municipal securities, 
and $18.7 million short-term securities.  The caption below the pie chart 
reads: The equity markets have generated significant value for RLI 
shareholders, as nearly 42% of our portfolio is invested in common stocks.  
Since 1982, our equity portfolio has averaged a 18.7% annual return.

The Company follows a program of matching assets to anticipated liabilities 
to ensure its ability to hold securities until maturity. The Company's known 
debt and long-term accounts payable are added to the estimate of its unpaid 
losses and settlement expenses by line of business. These anticipated 
liabilities are then factored against ultimate payout patterns. The resulting 
payout streams are funded with the purchase of fixed-income securities of 
like maturity. Management believes that interest rate risk can best be 
minimized by such asset/liability matching.

The Company intends to hold 87% of the securities in the Company's 
fixed-income portfolio until their contractual maturity. These securities are 
classified as held-to-maturity and are carried at amortized cost. A small 
portion (3%) of the fixed-income portfolio is classified as trading, with the 
unrealized capital gains and losses on these securities included in earnings, 
net of deferred income taxes. The remaining 10% are classified as 
available-for-sale and are carried at fair value. Unrealized capital 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. During 1997, the Company maintained 
$34.1 million in fixed income securities within the available-for-sale 
classification. Although it is likely that the majority of these securities 
will be held by the Company to maturity, they provide an additional source of 
liquidity and can be used to react to future changes in the Company's 
asset/liability structure.

The equity portfolios increased $62.5 million during 1997. The Company had 
net purchases of $6.9 million of


                                       28


<PAGE>

common stock, with a portfolio appreciation of $55.7 million. Capital gains 
of $2.0 million were realized during the year. The securities within the 
equity portfolio remain invested in conservative, blue-chip, value-oriented 
companies. Consistent dividend yield and performance is also valued as over 
25% of the portfolio is invested in the utility and telecommunications 
sectors. The general investment philosophy is to generate long-term portfolio 
growth. Trading is kept to a minimum.

The National Association of Insurance Commissioners (NAIC) continues its work 
on developing a model investment law. This law would regulate insurance 
company investments. The Company's current investment portfolio appears to be 
in compliance with the proposed model investment law. Management does not 
feel the proposed model law will affect its current strategies.

The NAIC has developed Property-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 asset (investment 
and credit) risk and underwriting (loss reserves, premiums written and 
unearned premium) risk. The NAIC model law calls for various levels of 
regulatory action based on the magnitude of an indicated RBC capital 
deficiency, if any. The RBC standards became effective for 1994 annual 
statement filings. The Company continues to monitor its subsidiaries' 
internal capital requirements and the NAIC's RBC developments. The Company 
has determined that its capital levels are well in excess of the minimum 
capital requirements for all RBC action levels. Management believes that the 
Company's capital levels are sufficient to support the level of risk inherent 
in its operations.

The NAIC has a project to codify statutory accounting practices, the result 
of which is expected to constitute the only source of "prescribed" statutory 
accounting practices. Accordingly, that project will likely change the 
definitions of what comprises prescribed versus permitted statutory 
accounting practices, and may result in changes to the accounting policies 
that insurance enterprises use to prepare their statutory financial 
statements.


OTHER MATTERS

The Company is aware of the issues associated with the programming code in 
existing computer systems as the millennium (Year 2000) approaches. The "Year 
2000" problem is pervasive and complex as many computerized systems are 
exposed to the rollover of the two-digit year value to 00. The issue is 
whether computer systems will properly recognize date-sensitive information 
when the year changes to 2000. Systems that do not properly recognize such 
information could generate erroneous data or cause a system to fail. 

The Company is utilizing both internal and external resources to identify, 
correct or modify, and test the systems for the Year 2000 compliance. It is 
anticipated that reprogramming efforts will be complete by December 31, 1998, 
allowing adequate time for testing. To date, confirmations have been received 
from the Company's primary system vendors that plans are being developed to 
address processing of transactions in the year 2000. Based on preliminary 
information, costs of addressing potential problems are not currently 
expected to have a material adverse impact on the Company's financial 
position, results of operations or cash flows in future periods. However, if 
the Company, its customers or vendors are unable to resolve such processing 
issues in a timely manner, it could result in a material financial risk.

From an underwriting perspective, the Company has identified potential 
exposures by product line. Management is investigating alternative solutions 
by consulting with other industry leaders in our lines of business. While all 
policies could be affected by Year 2000 issues, those lines the Company has 
identified to be most susceptible are: general liability, directors and 
officers liability, errors and omissions coverage, and property insurance.

The Company has temporarily ceased writing policies extending coverage beyond 
the year 1999. However, a small number of policies with Year 2000 exposures 
has been written. Insurance Services Office has created endorsements that 
exclude Year 2000 exposures, but state regulators have yet to address these 
exclusions. The states' reaction to these endorsements will help management 
decide what approach to ultimately take on coverages written beyond the year 
1999.

The following information appeared as an inset on the top right-hand corner 
of this annual report page: RLI Fact--Proactive Year 2000 efforts 
underway--RLI has identified Year 2000 risks by product line and system 
needs.  We anticipate few coverage exposures.  Internal system safeguards are 
expected to be completed in 1998.  This is an ongoing situation that we will 
continue to monitor and re-evaluate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A.  DESCRIPTION OF BUSINESS: RLI Corp. is a holding company that, through its 
subsidiaries, underwrites selected property and casualty insurance products.

The property and casualty insurance segment, RLI Insurance Group (the Group), 
is composed of two insurance companies. RLI Insurance Company, the principal 
subsidiary, writes multiple lines of insurance on an admitted basis in all 50 
states, the District of Columbia and Puerto Rico. Mt. Hawley Insurance 
Company, a subsidiary of RLI Insurance Company, writes multiple lines of 
insurance on an admitted basis in Kansas and surplus lines insurance in the 
remaining 49 states, the District of Columbia, Puerto Rico, the Virgin 
Islands and Guam.

B.  PRINCIPLES OF CONSOLIDATION AND BASIS OF PRESENTATION: The accompanying 
consolidated financial statements were prepared in conformity with generally 
accepted accounting principles (GAAP), which differ in some respects from 
those followed in reports to insurance regulatory authorities. The 
consolidated financial statements include the accounts of RLI Corp. and its 
subsidiaries (the Company). All significant intercompany balances and 
transactions have been eliminated.

On December 1, 1996, RLI Vision Corp., the Company's wholly-owned optical 
goods distributor, merged with Hester Enterprises, Inc., the manufacturer of 
Maui Jim sunglasses. The Company retained a 34% minority interest in the 
combined entity, renamed Maui Jim, Inc. The Company accounted for this merger 
as a non-monetary exchange of ownership interests with no gain or loss 
recognized.

As a result of the merger, the Company began presenting its minority interest 
in Maui Jim, Inc. under the equity method of accounting beginning December 1, 
1996. Additionally in 1996, for comparative purposes, the Company restated 
prior period financial information to present its 100% ownership in RLI 
Vision Corp. under the equity method. This restatement was a change in 
presentation only and had no impact on earnings. In January 1997, the Company 
paid $3,694,118 for an additional 10% ownership interest in Maui Jim, Inc., 
bringing the Company's total minority interest in Maui Jim, Inc. to 44%.

On May 4, 1995, RLI Vision Corp. acquired through merger Target Industries, 
Inc., a wholesale optical goods distributor of contact lenses, Rx spectacles, 
frames and sunglasses, located in Cohasset, Massachusetts. As consideration, 
RLI Corp. issued 313,500 shares of its common stock. This business 
combination was accounted for as a pooling-of-interests. The consolidated 
financial statements and related financial information for periods prior to 
the combination were, at the time, restated to include the accounts and 
results of operations of Target Industries, Inc., including Target 
Industries, Inc. stand-alone net income for the year ended December 31, 1994 
of $225,440.

As a result of the aforementioned merger with Hester Enterprises, Inc., the 
accounting for the merger with Target Industries, Inc. as a 
pooling-of-interests was no longer applicable. Accordingly, the 1996 
financial statements reflect an adjustment to shareholders' equity of 
$4,633,823 to recognize the change from pooling-of-interests to purchase 
accounting, and a charge to earnings of $732,847, or $.05 per diluted share, 
for cumulative goodwill amortization from May 4, 1995, through November 30, 
1996. Prior period financial information was not restated to reflect this 
change in accounting due to immateriality.

C.  SIGNIFICANT EVENT: On January 17, 1994, an earthquake occurred in the 
Northridge, California area.  Losses incurred as a result of this earthquake 
represent the largest single loss event in the Company's history. In 
September 1995, the Company strengthened loss reserves related to the 
Northridge Earthquake. While relatively minor development had occurred 
throughout the first six months of 1995, the third quarter claim-by-claim 
review indicated that greater future development was likely. The overall 
impact in 1995 of the Northridge Earthquake was a reduction to after-tax 
earnings by $18.6 million, or $1.93 per share.

This additional development resulted in part from hidden damage and increased 
business interruption losses on the Company's excess policies that, in 1994, 
were estimated by adjusters to be well within the coverage limits of the 
primary and underlying excess layers of reinsurance.  Also contributing to 
the increased development were unanticipated building code enactments, 
escalating construction costs, and the impact of reopened claims as a result 
of the involvement of public adjusters.

                                          34

As of December 31, 1997, the Company had 26 open earthquake claims from a 
total of 688 claims reported from this occurrence. No additional development 
from this event has occurred in 1996 or 1997. The Company continually 
monitors all open earthquake claims and current reserve levels. Management 
believes that the reserve strengthening performed in September 1995 is 
sufficient to resolve the remaining outstanding liabilities.

D.  INVESTMENTS: In compliance with Statement of Financial Accounting 
Standards (SFAS) No. 115, "Accounting for Certain Investments in Debt and 
Equity Securities," the Company classifies its investments in all debt 
securities and those equity securities with readily determinable fair values 
into one of three categories: held-to-maturity, trading, or 
available-for-sale.

HELD-TO-MATURITY SECURITIES
Debt securities that the Company has the positive intent and ability to hold 
to maturity are classified as held-to-maturity and carried at amortized cost. 
Except for declines that are other than temporary, changes in the fair value 
of these securities are not reflected in the financial statements. The 
Company has classified approximately 87% of its portfolio of debt securities 
as held-to-maturity.

TRADING SECURITIES
Debt and equity securities purchased for short-term resale are classified as 
trading securities. These securities are reported at fair value with 
unrealized gains and losses included in earnings. The Company has classified 
approximately 3% of its portfolio of debt securities as trading.

AVAILABLE-FOR-SALE SECURITIES
All other debt and equity securities not included in the above categories 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. All of the Company's equity securities 
and approximately 10% of debt securities are classified as available-for-sale.

Short-term investments are carried at cost, which approximates fair value.

The Company continuously monitors the values of its investments in fixed 
maturities and equity securities on an ongoing basis. If this review shows 
that a decline in fair value is other than temporary, the Company's carrying 
value in the investment is reduced to its estimated realizable value through 
an adjustment to earnings. Realized gains and losses on disposition of 
investments are based on specific identification of the investments sold.

Interest on fixed maturities and short-term investments is credited to 
earnings as it accrues. Dividends on equity securities are credited to 
earnings on the ex-dividend date.

E.  REINSURANCE: Ceded unearned premiums and reinsurance balances recoverable 
on unpaid losses and settlement expenses are reported separately as assets, 
instead of being netted with the appropriate liabilities, since reinsurance 
does not relieve the Company of its legal liability to its policyholders.

The Company continuously monitors the financial condition of its reinsurers. 
The Company's policy is to periodically charge to earnings an estimate of 
unrecoverable amounts from troubled or insolvent reinsurers. During 1995 and 
1996, the Company provided $613,296 and $1,006,140, respectively, for 
uncollectible reinsurance balances. No additional charges occurred in 1997. 
The Company believes that current reserve levels for uncollectible 
reinsurance are sufficient to cover the related exposure.

F.  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 settlement 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, with a resulting adverse 
effect on the Company. Based on the current assumptions used in calculating 
reserves, management believes that the Company's overall reserve levels at 
December 31, 1997, are adequate to meet its future obligations.

G.  REVENUE RECOGNITION: Insurance premiums are recognized ratably over the 
term of the contracts, net of ceded reinsurance. Unearned premiums are 
calculated on the monthly pro rata basis.

H.  POLICY ACQUISITION COSTS: The costs of acquiring insurance 
premiums--principally commissions and brokerage, sales compensation, premium 
taxes, and

                                          35

<PAGE>

other direct underwriting expenses--net of reinsurance commissions received, 
are amortized over the life of the policies in order to properly match policy 
acquisition costs to the related premium revenue. The method followed in 
computing deferred policy acquisition costs limits the amount of such 
deferred costs to their estimated realizable value, which gives effect to the 
premium to be earned, related investment income, losses and settlement 
expenses and certain other costs expected to be incurred as the premium is 
earned.

I.  PROPERTY AND EQUIPMENT: Property and equipment are depreciated on a 
straight-line basis for financial statement purposes over periods ranging 
from three to 10 years for equipment and up to 40 years for buildings and 
improvements.

J.  INCOME TAXES: The Company files a consolidated income tax return. Tax 
provisions are computed and apportioned to the subsidiaries on the basis of 
their taxable income.

K.  EARNINGS PER SHARE: In February 1997, the Financial Accounting Standards 
Board (FASB) issued Statement No. 128, "Earnings Per Share" (Statement 128). 
Statement 128 supersedes APB Opinion No. 15, "Earnings Per Share" (APB 15), 
and specifies the computation, presentation, and disclosure requirements for 
earnings per share (EPS) for entities with publicly held common stock or 
potential common stock. Statement 128 is effective for financial statements 
for both interim and annual periods ending after December 15, 1997. The 
Company adopted this statement during the fourth quarter of 1997. All prior 
period EPS data presented has been restated to conform to Statement 128.

Statement 128 replaces the presentation of primary EPS with a presentation of 
basic EPS and fully diluted EPS with diluted EPS. Basic EPS, unlike primary 
EPS, excludes dilution and is computed by dividing income available to common 
stockholders 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 (common stock equivalents) were 
exercised or converted into common stock. Diluted EPS is computed similarly 
to fully diluted EPS under APB 15. When inclusion of common stock equivalents 
increases the earnings per share or reduces the loss per share, the effect on 
earnings is antidilutive. Under these circumstances, the diluted net earnings 
or net loss per share is computed excluding the common stock equivalents.

Pursuant to disclosure requirements contained in Statement 128, the following 
represents a reconciliation of the numerator and denominator of the basic and 
diluted EPS computations contained in the financial statements:

For the year ended December 31, 1995, the calculation of dilutive EPS was 
anti-dilutive. As such, the effect of dilutive securities has been excluded. 
EPS as stated on a basic and diluted basis were equal.


L.  COMPREHENSIVE EARNINGS: Financial Accounting Standards Board (FASB) 
Statement No. 130, "Reporting Comprehensive Income," was issued in June 1997 
and becomes effective for interim and annual periods beginning after December 
15, 1997. The Company has elected early adoption of this Statement. The 
primary difference between reporting the Company's net and comprehensive 
earnings is that comprehensive earnings include unrealized gains/losses net 
of tax. Traditional reporting of net earnings directly credits or charges 
shareholders' equity with unrealized gains/losses, rather than including them 
in earnings. In reporting the

                                          36

<PAGE>

components of comprehensive earnings on a net basis in the income statement, 
the Company has used a 35% tax rate. Other comprehensive income, as shown, is 
net of tax expense of $19,516,100, $8,760,550, and $12,613,250, respectively, 
for 1997, 1996, and 1995.

M.  FAIR VALUE DISCLOSURES: The following methods were used to estimate the 
fair value of each class of financial instruments for which it was 
practicable to estimate that value. Fixed maturities and equity securities 
are valued using quoted market prices, if available. If a quoted market price 
is not available, fair value is estimated using quoted market prices of 
similar securities. Fair value disclosures for investments are included in 
note 2. Due to the relatively short-term nature of cash, short-term 
investments, accounts receivable, accounts payable and short-term debt, their 
carrying amounts are reasonable estimates of fair value. Fair value of 
long-term debt is based on quoted market prices if available or quoted market 
prices of similar issues.

N.  STOCK BASED COMPENSATION: The Company grants to officers and directors 
stock options for a fixed number of shares with an exercise price equal to or 
greater than the fair market value of the shares at the date of grant. The 
Company accounts for stock option grants in accordance with APB Opinion No. 
25, "Accounting for Stock Issued to Employees," and accordingly recognizes no 
compensation expense for the stock option grants. See note 8 for further 
discussion and related disclosures.

O.  RISKS AND UNCERTAINTIES: Certain risks and uncertainties are inherent to 
the Company's day-to-day operations and to the process of preparing its 
financial statements. The more significant risks and uncertainties, as well 
as the Company's methods for mitigating, quantifying, and minimizing such, 
are presented below and throughout the notes to consolidated financial 
statements.

CATASTROPHE EXPOSURES
The Company's past and present insurance coverages include exposure to 
catastrophic events. Catastrophic events such as earthquakes, floods, and 
windstorms are covered by certain of the Company's property policies. The 
Company has a concentration of such coverages in California (60.0% of gross 
property premiums written during 1997). Using computer-assisted modeling 
techniques, the Company quantifies and monitors its exposure to catastrophic 
events. The Company limits its risk to such catastrophes through the purchase 
of reinsurance. Utilizing the above, the Company attempts to limit its net 
aggregate exposure to a single catastrophic event to less than 10% of 
shareholders' equity.

ENVIRONMENTAL EXPOSURES
The Company is subject to environmental claims and exposures through its 
commercial umbrella, general liability and discontinued assumed reinsurance 
lines of business. Although exposure to environmental claims exists in these 
lines of business, management has sought to mitigate or control the extent of 
this exposure through the following methods: 1) the Company's policies 
include pollution exclusions that have been continually updated to further 
strengthen the exclusion; 2) the Company's policies primarily cover moderate 
hazard risks; and 3) the Company began writing this business after the 
industry became aware of the potential pollution liability exposure.

The Company has made loss and settlement expense payments on environmental 
liability claims and has loss and settlement expense reserves for others. The 
Company includes this historical environmental loss experience with the 
remaining loss experience in the applicable line of business to project 
ultimate incurred losses and settlement expenses and related "incurred but 
not reported" loss and settlement expense reserves.

Although historical experience on environmental claims may not accurately 
reflect future environmental exposures, the Company has used this experience 
to record loss and settlement expense reserves in the exposed lines of 
business. See further discussion of environmental exposures in note 6.

REINSURANCE
Reinsurance does not discharge the Company from its primary liability to 
policyholders, and to the extent that a reinsurer is unable to meet its 
obligations, the Company would be liable. The Company continuously monitors 
the financial condition of prospective and existing reinsurers. As a result, 
the Company currently attempts to purchase reinsurance from a limited number 
of financially strong reinsurers. The Company provides a reserve for 
reinsurance balances deemed uncollectible.

FINANCIAL STATEMENTS
The preparation of the consolidated financial statements in conformity with 
GAAP requires management to make estimates and assumptions that affect the 
reported financial statement balances as well as the disclosure of contingent 
assets and liabilities. Actual results could differ from those estimates. The 
most significant of these amounts is the liability for unpaid losses and 
settlement expenses. Management continually updates its estimates as 
additional data becomes available and adjusts the financial statements

                                          37

<PAGE>

as deemed necessary. Other estimates such as the recoverability of 
reinsurance balances, deferred tax assets and deferred policy acquisition 
costs are constantly monitored, evaluated, and adjusted. Although recorded 
estimates are supported by actuarial computations and other supportive data, 
the estimates are ultimately based on management's expectations of future 
events.

EXTERNAL FACTORS
The Company's insurance subsidiaries are highly regulated by the states 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, and regulate rates 
insurers may charge for various products. The Company is also subject to 
insolvency and guarantee fund assessments for policyholder losses covered by 
insolvent insurers. The Company generally accrues the full amount of the 
assessment upon notification.

The National Association of Insurance Commissioners (NAIC) has developed 
Property-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 asset (investment and credit) risk and 
underwriting (loss reserves, premiums written, and unearned premium) risk. 
The NAIC model law calls for various levels of regulatory action based on the 
magnitude of an indicated RBC capital deficiency, if any. The Company 
continuously monitors its subsidiaries' internal capital requirements and the 
NAIC's RBC developments. The Company has determined that its capital levels 
are well in excess of the minimum capital requirements for all RBC action 
levels. Management believes that the Company's capital levels are sufficient 
to support the level of risk inherent in its operations.

Expected maturities may differ from contractual maturities due to call 
provisions present on some existing securities. Management believes the 
impact of any calls should be slight and intends to follow its policy of 
matching assets against anticipated liabilities.

At December 31, 1997, the net unrealized appreciation of available-for-sale 
fixed maturities and equity securities totaled $86,852,663. This amount was 
net of deferred taxes of $46,448,300.  At December 31, 1996, the net 
unrealized appreciation of available-for-sale fixed maturities and equity 
securities totaled $50,608,696. This amount is net of deferred taxes of 
$26,932,200.

The Company is party to a securities lending program whereby fixed-income 
securities are loaned to third parties, primarily major brokerage firms. As 
of December 31, 1997 and 1996, fixed maturities with a fair value of 
$91,140,762 and $73,949,327, respectively, were loaned.  Agreements with 
custodian banks facilitating such lending require a minimum of 102% of the 
value of the loaned securities to be separately maintained as collateral for 
each loan. To further minimize the credit risks related to this lending 
program, the Company monitors the financial condition of counter parties to 
these agreements.

As required by law, certain fixed maturities and short-term investments 
amounting to $13,572,523 at December 31, 1997, were on deposit with either 
regulatory authorities or banks. Additionally, the Company has certain fixed 
maturities held in trust amounting to $9,545,572 at December 31, 1997. These 
funds cover net premiums, losses, and expenses related to a property and 
casualty insurance program.

The Company does not invest in derivative securities or collateralized 
mortgage obligations (CMOs).

4.  DEBT

On July 28, 1993, the Company issued $46.0 million of 6.0% convertible 
debentures that were to mature July 15, 2003, and pay interest semi-annually. 
The Company received $45,080,000 in net proceeds from the issue ($46,000,000 
principal less $920,000 of underwriting costs incurred) of which $30,500,000 
was contributed to the insurance subsidiaries to increase underwriting 
capacity and facilitate expansion of their business. The balance was retained 
for general corporate purposes, including debt service and the payment of 
dividends. All convertible debentures, unless previously redeemed, were 
convertible at the option of the holder at any time before maturity, into RLI 
Corp. common stock at an adjusted conversion price of $26.00 per share. The 
Company retained the option to redeem the convertible debentures, in whole or 
in part, on or after July 15, 1997, at specified redemption prices, plus 
accrued interest to redemption date. On June 20, 1997, the Company announced 
that it was calling for redemption all convertible debentures. The entire 
issue was to be redeemed for cash on July 22, 1997 at 103% of its principal 
amount, plus accrued interest. Holders of the debenture had the option to 
convert, at any time prior to the close of business on July 21, 1997, the 
debentures at an exchange rate of 38.4615 shares of RLI common stock for each 
$1,000 principal amount of convertible debt. On July 22, 1997, the entire 
$46.0 million had been converted into RLI common stock. This conversion 
created an additional 1,769,199 new shares of RLI common stock.

On December 1, 1995, the Company retired its 9.75% Industrial Development 
Bond of $6,255,000.  This tax-exempt issue was obtained by the Company on 
December 27, 1985, and proceeds were used by the Company to finance a portion 
of the acquisition, construction and equipping of an addition to the home 
office building and related facilities located in Peoria.  The retirement of 
the debt included a scheduled principal payment of $815,000, along with the 
execution by the Company of its first available call provision, to call the 
remaining debt of $5,440,000 at a 102 call premium.  The call was financed in 
part with available cash, along with short-term borrowings totaling 
$2,800,000.

During the first quarter of 1996, the Company paid off its short-term 
borrowings of $2,800,000, using excess funds from operations.

During 1997 the Company utilized its short-term credit facilities, as well as 
engaged in two reverse repurchase transactions, to partially fund the 
Company's common stock repurchase program.

Interest paid on outstanding debt for 1997, 1996, and 1995 amounted to 
$2,809,903, $2,834,192, and $3,372,479, respectively.

The Company maintains two sources of credit from one financial institution: a 
$30.0 million secured line of credit that cannot be canceled during its 
annual term, and a $3.0 million secured line of credit available for the 
issuance of letters of credit. As of December 31, 1997, the Company had 
$9,958,000 in outstanding short-term borrowings. Additionally, the Company 
was party to two reverse repurchase transactions totaling $14,942,000.

5.  REINSURANCE

In the ordinary course of business, the insurance subsidiaries assume and 
cede premiums with other insurance companies. A large portion of the 
reinsurance is effected under reinsurance contracts known as treaties and, in 
some instances, by negotiation on each individual risk. In addition, there 
are excess of loss and catastrophe reinsurance contracts that protect against 
losses over stipulated amounts arising from any one occurrence or event. The 
arrangements provide greater diversification of business and serve to limit 
the maximum net loss on catastrophes and large and unusually hazardous risks.

Through the purchase of reinsurance, the Company generally limits the loss on 
any individual risk to $1.0 million. Additionally, through extensive use of 
computer-assisted modeling techniques, the Company monitors the concentration 
of risks exposed to catastrophic events (predominantly earthquakes). The 
Company seeks to limit its estimated net aggregate exposure to a single 
catastrophic event to less than 10% of shareholders' equity.

In 1996, the Company entered into an innovative catastrophe reinsurance and 
loss financing program with Centre Reinsurance (Centre Re). The program, 
called Catastrophe Equity Puts (CatEPuts)-SM-, augments the Company's 
traditional reinsurance by integrating its loss financing needs with a 
pre-negotiated sale of securities linked to exchange-traded shares. CatEPuts 
allows the Company to put up to $50.0 million of its convertible preferred 
shares to Centre Re at a pre-negotiated rate in the event of a catastrophic 
loss, provided the loss does not reduce GAAP equity to less than $55.0 
million. CatEPuts is intended to be a three-year program and is designed to 
enable the Company to continue operating after a loss of such magnitude that 
its reinsurance capacity is exhausted. If the Company exercises its option to 
put preferred shares to Centre Re, then Centre Re, in turn, has the option to 
reinsure certain business written by the Company on a prospective basis.

Premiums written and earned along with losses and settlement expenses 
incurred for the years ended December 31 are summarized as follows:

At December 31, 1997, the Company had prepaid reinsurance premiums and 
reinsurance recoverables on paid and unpaid losses and settlement expenses 
with American Re-Insurance Company (rated A+ "superior" by A.M. Best Company) 
that amounted to $67,733,602. All other reinsurance balances recoverable, 
when considered by individual reinsurer, are less than 10% of shareholders' 
equity.

6.  UNPAID LOSSES AND SETTLEMENT EXPENSES

The following table reconciles the Company's liability for unpaid losses and 
settlement expenses (LAE) for the three years ended December 31, 1997. Since 
reserves are based on estimates, the ultimate net cost may vary from the 
original estimate. As adjustments to these estimates become necessary, they 
are reflected in current operations. As part of the reserving process, 
historical data is reviewed and consideration is given to the anticipated 
impact of various factors such as legal developments and economic conditions, 
including the effects of inflation. Changes in reserves from the prior years' 
estimates are calculated based on experience as of the end of each succeeding 
year (loss and LAE development).

</TABLE>

During 1997 and 1996, overall development on prior accident-year loss and 
settlement expense reserves was insignificant to operating results and 
recorded loss and settlement expense reserves. For 1995, however, prior 
accident-year development was significantly impacted by the effects of the 
1994 Northridge Earthquake. As previously discussed in note 1, the Company 
experienced $27.3 million of loss development from this event during calendar 
year 1995.

The Company is subject to environmental claims and exposures through its 
commercial umbrella, general liability, and discontinued assumed reinsurance 
lines of business. Within these lines, the Company's environmental exposures 
include environmental site cleanup, asbestos removal, and mass tort 
liability. The majority of the exposure is in the excess layers of the 
Company's commercial umbrella and assumed reinsurance books of business.

The table on the following page represents inception-to-date paid and unpaid 
environmental claims data (including incurred but not reported losses) for 
the periods ended 1997, 1996 and 1995:

Although the Company's environmental exposure is limited as a result of 
entering the liability lines after the industry had already recognized it as 
a problem, management cannot determine the Company's ultimate liability with 
any reasonable degree of certainty. This ultimate liability is difficult to 
assess due to evolving legislation on such issues as joint and several 
liability, retroactive liability, and standards of cleanup. Additionally, the 
Company participates primarily in the excess layers, making it even more 
difficult to assess the ultimate impact.

7.  INCOME TAXES

Management feels it is more likely than not that a portion of the Company's 
deferred tax assets will not be realized. Therefore, an allowance has been 
established for certain deferred tax assets that have an indefinite reversal 
pattern. Management also believes the Company's remaining deferred tax assets 
will be fully realized through deductions against future taxable income.

</TABLE>

The Company has recorded its deferred tax assets and liabilities using the 
statutory federal tax rate of 35%. Management believes when these deferred 
items reverse in future years, the Company's taxable income will be taxed at 
an effective rate of 35%.

Net federal and state income taxes paid (refunded) in 1997, 1996, and 1995 
amounted to $11,130,299, $1,415,994, and $(794,741), respectively.

The Internal Revenue Service (IRS) has examined the Company's income tax 
returns through the tax year ended December 31, 1990. For 1995, the Company's 
net taxes refunded include a $3.9 million refund received as a result of 
carrying back the 1994 net operating loss and capital loss to prior years. 
The IRS is currently examining the Company's income tax returns through the 
tax year ended December 31, 1994. Management believes any tax implication 
from examinations of these years should not materially impact the Company's 
consolidated financial position or results of operations.

8.  EMPLOYEE BENEFITS

PENSION PLAN
The Company maintains a non-contributory defined benefit pension plan 
covering substantially all employees meeting age and service requirements. 
The plan provides a benefit based on a participant's service and the highest 
five consecutive years' average compensation out of the last 10 years. The 
Company funds pension costs as accrued, except that in no case will the 
Company contribute amounts less than the minimum contribution required under 
the Employee Retirement Income Security Act of 1974 or more than the maximum 
tax deductible contribution for the year. The plan reached the full funding 
limitation in 1986 and remained fully funded through 1993. During 1995, 1996, 
and 1997, the Company made the maximum tax deductible contribution allowed, 
totaling $397,158, $413,977, and $453,146, respectively, to adequately meet 
the funding requirements of the plan.

The Company has made various amendments to the plan in order to comply with 
certain Internal Revenue Code changes.

The components of net periodic pension costs for each of the three years 
ended December 31, are as follows:

At December 31, 1997, plan assets at fair value are comprised of 
approximately 94% equity securities and 6% invested cash.

In 1997, the Company used the following rates to determine its projected 
benefit obligation: 7.25% settlement rate, 6% increase in salary, and 10% 
expected long-term return on plan assets. In 1996, the Company used a 
settlement rate of 7.5%, an increase in salary levels of 6%, and an expected 
long-term return on plan assets of 10% in determining the projected benefit 
obligation.

EMPLOYEE STOCK OWNERSHIP AND BONUS AND INCENTIVE PLANS
The Company has both an Employee Stock Ownership Plan (ESOP) and an officer 
performance incentive plan. In 1996, the Company adopted a new approach for 
evaluating the funding of these plans. Called the Market Value Potential 
(MVP) plan, the new program is designed to ensure that the interests of 
company insiders correspond with those of our shareholders. Beginning in 
1997, the Company established an additional provision allowing for employee 
bonus participation.

MVP requires that the Company generate a return on equity in excess of its 
cost of capital before either the funding of the ESOP or the payment of 
employee or officer bonuses. Under MVP, funds in excess of the cost of 
capital are first designated to fund the Company's ESOP up to the maximum 
allowable contribution of 15% of eligible wages. MVP in excess of the ESOP 
funding is then shared by the employees and officers of the Company and its 
shareholders. Employees can receive a maximum of 1% of the excess on an 
after-tax basis, while officers can receive a maximum of 8% of the excess on 
an after-tax basis. All remaining funds are reinvested in the Company for the 
benefit of the shareholders. MVP further restricts the officer payout in a 
given year. Officer payout is restricted to 60% of the combination of bonuses 
earned in the previous fiscal year plus any unpaid balance carried forward 
from prior years. The remaining 40% is at risk and is retained by the 
Company. This amount is posted to a participant's "bank account" and is 
subject to achieving the MVP target return in the succeeding fiscal year. In 
1997, $5,390,191 (7.91% of the excess return) was earned by officers under 
the plan. The actual officer payout of $3,857,990 (60% of bonus earned and 
bank balance for previous fiscal year) was completed in January 1998. 
Additionally, employee bonuses totaling $688,700 were earned under the plan 
in 1997 and were fully paid in January 1998. In 1996, $2,810,050 (7.07% of 
the excess return) was earned by officers under the plan. The actual payout 
of $1,686,030 (60% of bonus earned) occurred in January 1997.

The Company's ESOP is non-leveraged and covers substantially all employees 
meeting eligibility requirements. ESOP contributions are determined annually 
by the Company's board of directors and are expensed in the year earned. 
During 1997, 1996, and 1995, the Company recognized expense of $2,565,350, 
$2,791,463, and $2,046,474, respectively, related to the ESOP. At its 
December 1997 meeting, the board voted in favor of making a contribution to 
the ESOP for 1997 based on the MVP projections for the year. In 1996 and 
1995, the board had authorized this contribution as well.

During 1997, the ESOP purchased 63,841 shares of the Company's common stock 
on the open market at an average price of $33.28 ($2,124,461). During 1996, 
the ESOP purchased 76,500 shares of the Company's treasury stock at an 
average price of $25.38 ($1,941,288). During 1995, no shares were purchased. 
All shares held by the ESOP are treated as outstanding in computing the 
Company's earnings per share. Dividends on ESOP shares are passed through to 
the participants.

DIRECTORS DEFERRED COMPENSATION AND EXCESS ESOP
The Company has a deferred compensation plan for directors and an excess ESOP 
for key employees through which company shares are purchased for the 
directors and key employees. The Company funded the plans by establishing 
Rabbi Trusts and by purchasing company shares. Since the assets of the Rabbi 
Trusts are subject to claims of the Company's general creditors, such assets 
are recorded as other assets in the accompanying balance sheets. A 
corresponding liability for the same amount, which represents the Company's 
liability to its directors and key employees, is reflected as a component of 
other liabilities. During 1997, 1996, and 1995, the Company recognized 
expenses of $158,600, $139,075, and $145,550, respectively, under these 
plans. In 1997, the Rabbi Trusts purchased 7,743 shares of the Company's 
common stock on the open market at an average price of $39.52 ($306,027). In 
1996, the Rabbi Trusts purchased 10,560 shares of the Company's treasury 
stock, at an average price of $25.22 ($266,339) and 4,300 shares of the 
Company's common stock on the open market at an average price of $32.13 
($138,138). At December 31, 1997, the Trusts' assets were valued at 
$6,432,355.

STOCK OPTION PLAN
During 1995, the Company adopted and the shareholders approved an Incentive 
Stock Option Plan (the Incentive Plan). During 1997, the shareholders 
approved the Outside Directors' Stock Option Plan (the Directors' Plan). The 
Company accounts for the plan in accordance with APB Opinion No. 25, under 
which no compensation cost has been recognized.

Had compensation cost for the plan been determined consistent with FASB 
Statement No. 123, "Accounting for Stock-Based Compensation," the Company's 
net income and earnings per share would have been reduced to the following 
pro forma amounts:

</TABLE>

These pro forma amounts may not be representative of the effects of FASB 
Statement No. 123 on pro forma net income for future years because options 
vest over several years and additional awards may be granted in the future.

Under the Incentive Plan, an officer may be granted an option to purchase 
shares at 100% of the grant date fair market value (110% if the optionee and 
affiliates own 10% or more of the shares), payable in cash. An option may be 
granted only during the 10-year period ending in May 2005. An optionee must 
exercise an option within 10 years (five years if the optionee and affiliates 
own 10% or more of the shares) from the grant date, or three months after the 
optionee ceases to be an employee, whichever occurs first. Full vesting of 
options granted occurs at the end of five years.

Under the Directors' Plan, shares granted are not incentive stock options. 
Directors may be granted non-qualified options to purchase shares at 100% of 
the grant date fair market value. An optionee must exercise an option within 
10 years from the grant date. Full vesting occurs at the end of three years, 
except in the case of death, disability, or termination of Director status, 
at which time all options become fully vested and exercisable.

Additionally, subject to the Directors' Plan's approval by shareholders, the 
Directors' Plan included a grant of 24,000 shares (3,000 per Director) 
effective on May 2, 1996. Shareholder approval occurred at the May 1997 
shareholder meeting. As a result, 1996 plan data, as provided, has been 
restated to include the impact of this grant.

The Company may grant options for up to 1,250,000 shares under the Incentive 
Plan and 200,000 shares under the Directors' Plan. Through December 31, 1997, 
the Company has granted 232,875 options under these plans. Under both plans, 
the option exercise price equals the stock's market price on the date of 
grant.

A summary of the status of the plans at December 31, 1997, 1996 and 1995, and 
changes during the years then ended are presented in the following table and

The fair value of each option grant is estimated on the date of grant using 
the Black-Scholes option pricing model with the following weighted-average 
assumptions used for grants in 1997, 1996 and 1995, respectively: risk-free 
interest rates of 6.64%, 6.82% and 6.67%; expected dividend yields of 3.10%, 
3.15% and 3.14%; expected lives of 10 years; and expected volatility of 
26.30%, 27.35% and 28.46%.

Dividend payments to the Company from its principal insurance subsidiary are 
restricted by state insurance laws as to the amount that may be paid without 
prior notice or approval of the regulatory authorities of Illinois and 
California. The maximum dividend distribution is limited by Illinois and 
California law to the greater of: 10% of RLI Insurance Company's policyholder 
surplus as of December 31 of the preceding year, or the net income of RLI 
Insurance Company for the 12-month period ending December 31 of the preceding 
year. Therefore, the maximum dividend distribution that can be paid by RLI 
Insurance Company during 1998 without prior notice or approval amounts to 
$26,552,617--10% of RLI Insurance Company's 1997 policyholder surplus. The 
actual amount paid to the Company during 1997 was $16,678,225.

10.  COMMITMENTS AND CONTINGENT LIABILITIES

The Company is involved in certain legal proceedings and disputes considered 
by management to be ordinary and incidental to the business, or which have no 
foundation in fact. Management believes that valid defenses exist as to all 
such litigation and disputes and is of the opinion that these will not have a 
material effect on the Company's financial statements.

In November 1988, California voters approved Proposition 103, which requires 
insurance rates for certain lines of business to be rolled back 20% from the 
rates in effect in November 1987. Beginning in 1989 and ending in 1994, the 
Company deferred premium revenue of $1,449,200 and accrued interest in the 
amount of $1,050,480 to cover the proposed rollback. No additional provision 
was made during 1995 and the total funds accrued for rollback remained 
$2,499,680 at December 31, 1995.

During 1996, the Company reached a settlement with the California Department 
of Insurance resolving its total liability for refunds and interest under 
Proposition 103. The settlement requires the Company to pay $2,987,050 in 
refunds and interest. In the second quarter of 1996, the Company recorded a 
pretax charge of $487,370 to record the difference between the actual 
settlement and the amount previously accrued. During 1997, the Company issued 
refund checks to policyholders. As of December 31, 1997, the total unclaimed 
refund amounted to $1,526,283. Any amounts unclaimed as of November 1, 1998 
will escheat to the California Division of Unclaimed Property.

The Company leases regional office facilities and automobiles under operating 
leases expiring in various years through 2002. Minimum future rental payments 
under non-cancellable operating leases are as follows:

(1) Since the weighted-average shares for the quarters are calculated 
independently of the weighted-average shares for the year, and due to the 
exclusion of the antidilutive effects as discussed in note 1K, quarterly 
earnings per share may not total to annual earnings per share.

(2) Operating earnings per share is calculated by reducing net earnings by 
the after-tax impact of net realized investment gains.

REPORT OF INDEPENDENT AUDITORS

The board of directors and shareholders
RLI Corp.

We have audited the accompanying consolidated balance sheets of RLI Corp. and 
Subsidiaries as of December 31, 1997 and 1996, and the related consolidated 
statements of earnings and comprehensive earnings, shareholders' equity, and 
cash flows for each of the years in the three-year period ended December 31, 
1997. These consolidated financial statements are the responsibility of the 
Company's management. Our responsibility is to express an opinion on these 
consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. 
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audits provide a 
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above 
present fairly, in all material respects, the financial position of RLI Corp. 
and Subsidiaries at December 31, 1997 and 1996, and the results of their 
operations and their cash flows for each of the years in the three-year 
period ended December 31, 1997, in conformity with generally accepted 
accounting principles.

STATEMENT OF FINANCIAL REPORTING RESPONSIBILITY

The management of RLI Corp. and Subsidiaries is responsible for the 
preparation and for the integrity and objectivity of the accompanying 
financial statements and other financial information in this report. The 
financial statements have been prepared in accordance with generally accepted 
accounting principles and include amounts that are based on management's 
estimates and judgments.

The accompanying financial statements have been audited by KPMG Peat Marwick 
LLP (KPMG), independent certified public accountants, selected by the audit 
committee and approved by the shareholders. Management has made available to 
KPMG all the Company's financial records and related data, including minutes 
of directors' meetings. Furthermore, management believes that all 
representations made to KPMG during its audit were valid and appropriate.

Management has established and maintains a system of internal controls 
throughout its operations that are designed to provide assurance as to the 
integrity and reliability of the financial statements, the protection of 
assets from unauthorized use, and the execution and recording of transactions 
in accordance with management's authorization. The system of internal 
controls provides for appropriate division of responsibility and is 
documented by written policies and procedures that are updated by management 
as necessary. Certain aspects of these systems and controls are tested 
periodically by the Company's internal auditor. As part of its audit of the 
financial statements, which is performed in accordance with generally 
accepted auditing standards, KPMG considers certain aspects of the system of 
internal controls to the extent necessary to form an opinion on the financial 
statements and not to provide assurance on the system of internal controls. 
Management considers the recommendations of its internal auditor and 
independent public accountants concerning the Company's internal controls and 
takes the necessary actions that are cost effective in the circumstances to 
respond appropriately to the recommendations presented. Management believes 
that as of December 31, 1997, the Company's system of internal controls was 
adequate to accomplish the objectives described herein.

The audit committee is comprised solely of four non-employee directors and is 
charged with general supervision of the audits, examinations and inspections 
of the books and accounts of RLI Corp. and Subsidiaries. It also recommends 
to the board of directors the firm of independent public accountants to be 
engaged to audit the annual consolidated financial statements, and it meets 
regularly with those independent public accountants and with management, both 
separately and together. The independent public accountants and the internal 
auditor have ready access to the audit committee.
