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 I.

(c)  Narrative Description of Business

                               RLI INSURANCE GROUP

     RLI Insurance Group is composed primarily of four main insurance companies.
RLI Insurance Company, the principal subsidiary, writes multiple lines 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
surplus lines insurance in all 50 states, the District of Columbia, Puerto Rico,
the Virgin Islands and Guam. Underwriters Indemnity Company ("UIC"), a
subsidiary of RLI Insurance Company, writes multiple lines insurance on an
admitted basis in Alabama, Arkansas, Delaware, District of Columbia, Georgia,
Idaho, Illinois, Kansas, Kentucky, Mississippi, Missouri, Nebraska, Nevada, New
Mexico, North Carolina, North Dakota, Oregon, South Carolina, South Dakota,
Tennessee, Texas, Utah, West Virginia and Wyoming and surplus lines in
California, Colorado, Hawaii, Indiana, Louisiana, Montana, Nevada, Ohio,
Oklahoma, Pennsylvania, Washington and Wisconsin. Planet Indemnity Company
("PIC"), a subsidiary of UIC, writes multiple lines insurance on an admitted
basis in Colorado, Florida, Idaho, Illinois, Michigan, North Dakota and
Pennsylvania and surplus lines in Alabama, California, District of Columbia,
Georgia, Hawaii, Indiana, Kansas, Kentucky, Missouri, Nebraska, Ohio, Oregon,
South Dakota, Texas, Washington, West Virginia and Wyoming. Other companies in
the RLI Insurance Group include: Replacement Lens Inc., RLI Insurance Agency,
Ltd., RLI Insurance Ltd. and Underwriters Indemnity General Agency, Inc.

     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 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.

                                       2
<PAGE>

     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 catastrophic losses, such as Hurricane
Andrew and the Northridge Earthquake, property rates hardened in California,
Florida and the wind belt, but remained soft in other areas of the country. In
1994 and 1995, rates hardened and premium growth was achieved in the commercial
property book of business. Otherwise, rates for property and casualty lines have
declined over time. To maintain profitability, underwriters have tightened
selection criteria, broadened their focus to other market segments and given up
business where rates dropped too low. At the end of 1999, a trend emerged of
modest firming in the pricing of branch office business which may indicate an
improvement in industry underwriting discipline.

     The Company initially wrote specialty property and casualty insurance
through independent underwriting agents. The Company opened its first branch
office in 1984, and began to shift 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 Markets
Division and the Surety Division. The Company produces business under agreements
with underwriting general agents. Additional underwriting agents are accepted
under the auspices of Company product vice presidents. The majority of the
specialty property and casualty business is marketed through the Specialty
Markets and Surety divisions and branch offices located in Los Angeles,
California; San Francisco, California; Glastonbury, Connecticut; Atlanta,
Georgia; Alpharetta, Georgia; Honolulu, Hawaii; Chicago, Illinois; Overland
Park, Kansas; Boston, Massachusetts; St. Paul, Minnesota; New York City, New
York; Dallas, Texas; Houston, Texas; and Seattle, Washington.

     The following table provides for the year ended December 31, 1999 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, 1999, 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:

                                       3

<PAGE>

A.       PROPERTY SEGMENT

         1.     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 written in the United States and abroad. The Company writes coverage
for a wide range of commercial and industrial classes such as office buildings,
apartments, condominiums, certain industrial and mercantile structures,
buildings under construction and movable equipment. The Company also writes
boiler and machinery and ocean marine insurance under the same management as
commercial property. The Alpharetta, Boston, Chicago, Dallas, Houston, Los
Angeles and San Francisco branch offices are responsible for underwriting this
coverage. In 1999, 1998 and 1997 net earned premiums totaled $43,918,000,
$42,281,000 and $48,799,000, or 19%, 25% and 29%, respectively, of the Company's
consolidated revenues.

         2.     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 totaled $6,850,000, $9,689,000 and $13,229,000, or
3%, 6% and 8% of the Company's consolidated revenues for 1999, 1998 and 1997,
respectively.

         3.     OTHER. The Company acquired property business as a part of the
acquisition of Underwriters Indemnity Holdings on January 29, 1999. All property
coverages associated with this business are being non-renewed in accordance with
allowed policy provisions. In 1999, net earned premiums totaled $622,000 or less
than 1% of the Company's consolidated revenue.


B.       SURETY SEGMENT

         4.     SURETY. The Company underwrites this product line from the Home
Office in Peoria and through our branch facilities in Dallas, Houston, New York
and Seattle. The division focuses on writing contract bonds for small size
contractors, energy-related business for oil and gas operators and a wide range
of commercial surety bonds through the independent agency system. Net earned
premiums totaled $25,412,000, $18,307,000 and $11,491,000, or 11%, 11% and 8% of
the Company's consolidated revenues for 1999, 1998 and 1997, respectively.


C.       CASUALTY SEGMENT

         5.    GENERAL LIABILITY. The Company writes general liability
coverages through its Los Angeles, 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 risks. Net
earned premiums totaled $31,149,000, $23,726,000 and $26,332,000, or 14%, 14%
and 16% of the Company's consolidated revenues for the years 1999, 1998 and
1997, respectively.

         6.     COMMERCIAL AND PERSONAL UMBRELLA LIABILITY. The Company's
commercial umbrella coverage is produced through its Overland Park, St. Paul,
Alpharetta, Glastonbury, Los Angeles 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 $58,956,000, $29,086,000 and $22,566,000, or 26%, 17% and 12% of the
Company's consolidated revenues for the years 1999, 1998 and 1997,
respectively.

         7.     EXECUTIVE PRODUCTS. The Company produces financial products
such as Directors' and Officers' Liability through underwriting facilities in
Dallas, Los Angeles and New York City. The Company offers Miscellaneous
Professional Liability for a variety of low to moderate classes of risks. D&O
is a relatively small component of the overall P&C market, which has been
subject to severe competition. Underwriters have relinquished market share
rather than accept inadequate pricing. The package of coverages offered has
been expanded to include a variety of coverages of interest to corporations
and executives, such as Employment Practices Liability and Fiduciary

                                       4

<PAGE>

Liability. This is designed to give the product broader appeal. Net earned
premiums totaled $2,647,000, $3,054,000 and $4,430,000, or 1%, 2% and 3% of the
Company's consolidated revenues for the years 1999, 1998 and 1997, respectively.

         8.     PROGRAM BUSINESS. The Company began writing Program Business
in 1998 with one Habitational Program offered through a broker in Parsippany,
New Jersey. In 1999 offerings were expanded to include Farmowners coverage in
three states written through a broker in Omaha, Nebraska. Primary package
policies are the primary offerings in both programs. Expansion of these
current programs and the introduction of new programs is planned for 2000.
Program underwriting is headquartered in the Dallas branch office. Net earned
premiums totaled $456,000 and $21,000 for 1999 and 1998, respectively.

         9.     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 produce business through
independent agents and brokers nationwide. Net earned premiums totaled
$9,647,000 and $3,806,000, or 4% and 2% of the Company's consolidated
revenues for 1999 and 1998, respectively.

         10.    OTHER. Smaller programs offered by the Company include:
excess medical, deductible buy-back, in-home business, personal automobile
(Hawaii only), and employer's excess indemnity. Net earned premiums from
these lines totaled $15,617,000, $12,354,000 and $9,907,000, or 6%, 6% and 5%
of the Company's consolidated revenues for the years, 1999, 1998 and 1997,
respectively.

COMPETITION

         The Company's specialty property and casualty insurance subsidiaries
are part of an extremely competitive industry which is cyclical and
historically characterized by periods of high premium rates and shortages of
underwriting capacity followed by periods of severe competition and excess
underwriting capacity. Within the United States alone, approximately 2,500
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
is a leader in using the internet to conduct e-business for products that
lend themselves to that approach. 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, Puerto
Rico, the Virgin Islands and Guam. 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. Since 1996, competition
reasserted itself and the Company reduced rates somewhat. Towards the end of
1999, a favorable trend emerged of price firming on commercial business,
driven in part by the reinsurance market. The Company has 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 to "A" (Excellent). During 1999, A.M. Best
reaffirmed "A" ratings for both RLI Insurance Company and Mt. Hawley Insurance
Company. Underwriters Indemnity Company's (an indirect subsidiary of the
Company) A.M. Best rating for 1999 was "A-" (Excellent). Planet Indemnity
Company's (an indirect subsidiary of the Company) A.M. Best rating for 1999 was
"A-" (Excellent).

                                       5

<PAGE>

         During 1997, the Company, for the first time, applied for and
received a claims-paying rating from Standard & Poor's. As a result, a rating
of "A" (Good) was received for the combined insurance operation. In 1999, the
"A" rating was upgraded to "A+", as Standard & Poor's cited the Company's
strong operating performance, capitalization and risk management.

         A.M. Best ratings for the industry range from "A++" (Superior) to
"F" (In Liquidation) with some companies not being rated. Standard & Poor's
ratings for the industry range from "AAA" (Superior) to "CC" (Default
Expected). Publications of both A.M. Best and Standard & Poor's indicate that
"A" and "A+" ratings are assigned to those companies that, in their opinion,
have achieved excellent overall performance when compared to the standards
established by these firms 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, both firms review 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 and
loss reserves, the adequacy of its surplus, its capital structure and the
experience and objectives of its management. These ratings are based on
factors relevant to policyholders, agents, insurance brokers and
intermediaries and are not directed to the protection of investors.

         As of December 31, 1999, the Company had no public debt outstanding;
therefore, no debt rating existed.

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 $129,886,000, $135,269,000 and $138,198,000 in 1999, 1998
and 1997, 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.

         The Company attempts to purchase reinsurance from a 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, 1999, the Company had reinsurance recoverables on paid and
unpaid losses and settlement expenses of $66,274,000 with American
Re-Insurance Co. and $30,984,000 with Transatlantic Reinsurance Company (both
companies rated "A++" (Superior) by A.M. Best Company). 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 before reinsurance payables from such reinsurers as of
December 31, 1999. Also shown are the amounts of written premium ceded by the
Company to such reinsurers during 1999.

         As of December 31, 1999, the Company held $17,851,000 in irrevocable
letters of credit, $7,645,000 undertrust agreements and $1,930,574 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. In 1999, the Company limited
its maximum retained exposure on any one risk to $700,000. 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 1999, the Company's underwriting was supported by up to
$250,000,000 in traditional catastrophe reinsurance protection. The Company
continuously monitors and quantifies its exposure to earthquake risk, the
most significant catastrophe exposure to the Company, by means of catastrophe
exposure models developed by independent experts in that field. For the
application of the catastrophe exposure models, exposure and coverage detail
is recorded at each risk location. The model results are used both in the
underwriting analysis of individual risks, and at a corporate level for the
aggregate book of catastrophe exposed business. From both perspectives we
consider the potential loss produced by events with a Richter magnitude (a
measure of the energy released by an earthquake event) equivalent to the
earthquake on those faults which represent the greatest loss potential to the
Company, which are expected to recur at average intervals of 100 years, or
6.5 magnitude, whichever is greater. The probability that an earthquake event
would exceed our reinsurance cover (including facultative, excess of loss,
surplus, and cat treaty) is 2.18%. In addition, we examine the portfolio
exposure considering all possible earthquake events of all magnitudes and
return periods, on all faults represented in the model. The probability that
an earthquake event would exceed our reinsurance cover and 100% of our
surplus is 0.39%. The total exposure of the Company, as measured by the
catastrophe model output, is managed on a net of reinsurance basis to conform
to the operating risk constraint adopted by the Company's Board of Directors.

         In 1999, the Company continued its innovative catastrophe
reinsurance and loss financing program with Zurich Reinsurance NA (Zurich
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 Zurich 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 began as a multi-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 Zurich Re, then Zurich 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 1970s, substantial underwriting
losses in the early 1980s 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. Since 1993, the industry experienced
improvement in underwriting losses, particularly in years with fewer
catastrophe 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. For 1999, the industry's
statutory combined ratio is estimated to be 107.0, which represents a
deteriorating trend. The Company believes that certain other factors affect
its ability to underwrite specialty lines successfully, including:

                                       7

<PAGE>

         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 product distribution falls into distinct categories,
with binding authority following the categorization.

         BROKER BUSINESS. The largest volume of broker generated premium is
Commercial Property, General Liability, Commercial Umbrella and Commercial
Automobile. This business is produced through wholesale and retail brokers
who are not affiliated with the Company.

         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. Homeowners Dwelling Fire and
Personal Auto are produced through independent agents in Hawaii. 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 an
underwriting general agency to underwrite contract surety business on behalf
of RLI, primarily in Eastern states. An underwriting agency in San Francisco
is authorized to underwrite commercial umbrella business in select Western
states. An underwriting agency in New York is authorized to underwrite and
handle claims for low limit deductible buy-backs on program business,
primarily in the East. Other underwriting agencies have been designated to
underwrite programs involving various selected commercial insurance products.

         These underwriting general agencies may 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 -- RLI
Insurance Group 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 the handling and resolution of all claims and
directs all outside legal and adjustment specialists on an individual claim
and/or audit basis. 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.

                                       8

<PAGE>

         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 1999, 1998 and 1997 were 4%, 6% and 7%, 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.

         The following table represents inception-to-date paid and unpaid
environmental claims data (including incurred but not reported losses) for
the periods ended 1999, 1998 and 1997:

         Although the Company's environmental exposure is limited as a result
of entering 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.

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.

                                       9

<PAGE>

         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.

         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 settlement 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, 1999 are adequate to meet its future obligations.

         Explanation of significant components of reserve development by
calendar year are as follows:

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.

1998     During 1998, the Company experienced $3,403,000 of favorable
         development on loss reserves. This development was the net result of
         several reserve adjustments among various programs. Reserve
         strengthening of $2,600,000 to the surety line of business in the third
         quarter was offset by favorable development in, primarily, the personal
         umbrella product. Favorable development of approximately $3,000,000 on
         a deductible buy-back program resulted in a corresponding increase in
         contingent commissions and subsequently no impact on earnings.

1999     During 1999, the Company experienced $4,596,000 of favorable
         development on loss reserves. This development resulted from
         approximately $2,917,000 of favorable development in the property lines
         of business and approximately $1,679,000 of favorable development in
         the casualty lines of business. The favorable property development is a
         continuing result of the Northridge Earthquake claims from the 1994
         accident year settling for less than the open reserves. Favorable
         development of $1.1 million on casualty claims resulted from claim
         settlements and reevaluations of case reserves during the accounting
         period which were, in the aggregate, less than the IBNR and case
         reserves established at the beginning of the period. The remaining
         $579,000 of casualty favorable development resulted from balances due
         from insolvent reinsurers that had previously been written off.

         The table on the following page presents the development under
         generally accepted accounting principles of the Company's balance sheet
         reserves from 1990 through 1999. 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.

     The Company also calculates the statutory combined ratio, which is not
indicative of GAAP underwriting profits due to accounting for 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.

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

     During 1999, operating cash flows were used to acquire fixed income
instruments composed primarily of intermediate-term municipal and U.S.
Government and agency securities. RLI's mix of tax-exempt and taxable
instruments within the portfolio is decided at the time of purchase on the
basis of available after-tax returns and overall taxability of all invested
assets. Almost all securities reviewed for purchase are either high grade
municipal or U.S. Government or agency 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). As of December 31, 1999, 98% of the fixed income portfolio was rated AA
or better. Interest rate risk is limited by restricting and managing
acceptable call provisions among new security purchases.

     The municipal bond component of the fixed maturity portfolio increased
$16.0 million, to $188.1 million; and comprised 54.9% of the Company's total
fixed maturity portfolio, up 2.6 percentage points from year-end 1998. The
taxable U.S. Government and agency portion of the fixed income portfolio
increased by $7.3 million to $151.0 million, or 44.1% of the total versus
43.7% at year-end 1998. Investment grade corporate securities totaled $3.4
million compared to $4.2 million at

                                      15
<PAGE>

year-end 1998. The $8.9 million  convertible  debenture  portfolio  carried
at year-end 1998 was liquidated in 1999 with proceeds directed to the fixed
income portfolio.

     The Company follows a program of matching assets to anticipated
liabilities to ensure its ability to hold securities until maturity. 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 both
liquidity and interest rate risk can best be minimized by such
asset/liability matching.

     Aggregate maturities for the fixed maturity securities are as follows:

$284.6 million, a decrease of $11.9 million from the $296.5 million held at
the end of 1998. During 1999, net common equity investments totaling $2.8
million were sold and pretax unrealized depreciation of equity securities
totaled $15.3 million. Equity securities represented 41.2% of cash and
invested assets at the end of 1999, a decrease from the 43.8% at year-end
1998. As of the year-end, total equity investments held at the operating
companies represented 93.1% of the combined statutory surplus of the
insurance subsidiaries.

         Combined cash and short-term investments totaling $64.1 million at
year-end 1999 represented 9.3% of cash and invested assets versus 7.7% last
year. The Company's short-term investments consist of U.S. Government and
agency backed money market funds and the highest rated commercial paper.

         Under generally accepted accounting principles, equity and fixed
income securities are carried at fair market value. However, 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 their originally
scheduled maturity dates. Consequently, fluctuations in the market value of
most bonds are not reflected in the financial statements and do not affect
shareholders' equity.

                                     REGULATION

          STATE REGULATION

         As an insurance holding company, RLI Corp., as well as its insurance
subsidiaries, are subject to regulation by the states in which the insurance
subsidiaries are domiciled or transact business. Holding company registration in
each insurer's state of domicile requires reporting to the state regulatory
authority the financial, operational and management data of the insurers within
the holding company 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 regulators is required prior
to the consummation of certain transactions affecting insurance subsidiaries of
the holding company system.

         Other regulations 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. Regulations designed to ensure financial solvency
of insurers and to require fair and adequate treatment and service for
policyholders are enforced by filing, reporting and examination requirements.
Market oversight is conducted by monitoring trade practices, approving policy
forms, licensing of agents and brokers, and requiring fair and equitable
premiums and commission rates. Financial solvency is monitored by minimum
reserve and capital requirements, periodic reporting procedures (annually,
quarterly, or more frequently if necessary), and periodic examinations.

                                      17

         The quarterly and annual financial reports to the states utilize
accounting principles which are different from the generally accepted
accounting principles that show the business as a going concern. The
statutory accounting principles used by regulators, in keeping with the
intent to assure policyholder protection, are generally based on a
liquidation concept. The National Association of Insurance Commissioners
(NAIC) has recently developed a codified version of these statutory
accounting principles, and its deployment in the near future will foster more
consistency among the states for accounting guidelines and reporting.

         State 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 to operate in the state through
a corporation. In a few states, licenses are issued only to individual
residents.

         COMMERCIAL LINES DEREGULATION -- The NAIC and several state
legislatures have taken up the issue of commercial lines deregulation in an
attempt to streamline specific areas of insurance regulation. A growing
contingent in the regulatory community has acknowledged that some regulatory
procedures and practices may be cumbersome and inappropriate for commercial
buyers of insurance. Specifically, the large, sophisticated, multi-state or
multinational businesses that employ their own teams of risk managers to
evaluate, reduce and finance their loss exposures are less likely to need the
form and rate protections that regulators provide consumers and small to
medium business endeavors. And, while these large businesses may receive some
benefit from the state financial regulation of licensed insurers, it has long
been acknowledged that they do not need the protections addressed by the
barriers to the surplus lines market and other nontraditional markets.
Indisputably, deregulation of the licensed market will have an impact on the
surplus lines insurance carriers, which have been free from form and rate
requirements.

         USE OF CREDIT REPORTS IN UNDERWRITING -- Gains in access to
electronic commerce, and the means to gather information more rapidly, have
spurred regulators to take a second look at the use of consumer credit
reports in underwriting and rate making. In some states, regulators charged
with protecting insurance consumers from unfair trade practices are concerned
that some consumers' risks may be underwritten based solely on their credit
standing, and have sought to strengthen their laws and regulations to address
this. This trend comes on the heels of Congress' re-tooling of the Fair
Credit Reporting Act in 1997, which specifically addresses this issue, and
permits the use of consumer credit reports in underwriting. The issue of
federal preemption of state action in this arena has not been judicially
addressed.

         FEDERAL REGULATION

         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 federal preemption of
state auto liability laws, tax reform measures, product liability and
electronic commerce. The Company is also monitoring the following federal
proposals:

         NATURAL DISASTER ACT--Recent natural disasters, including Atlantic
Coast hurricanes, continue to fuel concern regarding the best way to provide
affordable insurance coverage for such events. Congress has yet to pass
legislation, but proposals to set up a system for federal relief to the
industry continue to be discussed. Two Initiatives, "The Natural Disaster
Protection and Insurance Act of 1997" (S.1361), and "The Homeowners Insurance
Availability Act of 1997" (H.R. 21), focus on excess federal reinsurance. In
1999, both the House and Senate introduced versions of the "Policyholder
Disaster Protection Act", which would permit insurers to build tax deferred
catastrophe reserves. The Company will continue to monitor the progress of
this issue.

                                       18

         FINANCIAL SERVICES MODERNIZATION -- The Gramm-Leach-Bliley Act was
signed into law by President Clinton on November 12, 1999. The principal
focus of the Act is to facilitate affiliations among banks, securities firms
and insurance companies. The Act amends the Federal Bank Holding Company Act
by creating a new category of bank holding company known as a "financial
holding company" to engage in activities that are "financial in nature," such
as securities and insurance. The Act repealed the Glass-Steagall Act, which
prohibited a Federal Reserve System member bank from being affiliated with a
securities firm; repealed the Garn-St. Germain Act, which prohibited a bank
holding company and its subsidiaries from selling or underwriting insurance;
and repealed the Federal Bank Holding Company Act provisions that prohibited
a director, officer or employee of a securities firm from serving as a
director, officer or employee of a bank.

         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 subsidiaries' 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 producers by regulatory authorities in the
states in which it operates.

         RLI Insurance Company obtained service mark registration of the
letters "RLI" in 1998 in the U.S. Patent and Trademark Office. Such
registration protects the mark nationwide from deceptively similar use by the
Company's competitors. The duration of this registration is ten years unless
renewed.

                             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.

                MANAGEMENT'S DISCUSSION & 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 86% 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 targeted 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 approximately 52% of the Company's 1999 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.

The casualty portion of the Company's business consists largely of commercial
and personal umbrella, general liability, and commercial auto 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 segment of RLI specializes in writing small- and medium-sized
commercial and contract surety products, as well as those for the energy,
petrochemical and refining industries. The commercial surety products usually
involve a statutory requirement for bonds. 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 deterioration of a contractor's financial condition.

The consolidated financial statements and related notes found on pages 26-48,
and the "Forward Looking Statements" on page 4, should be read in conjunction
with the following discussion.

Significant Developments

In January 1999, RLI Insurance Company acquired Underwriters Indemnity
Holdings, Inc. (UIH), located in Houston, Texas. UIH specializes in the
marketing and underwriting of surety products for energy, petrochemical and
refining exposures.

RLI paid $40.7 million in cash in exchange for all outstanding shares of UIH.
Included in the transaction are both of UIH's insurance operating
subsidiaries, Underwriters Indemnity Company of Texas and Planet Indemnity
Company of Illinois. The transaction was financed through short-term
borrowings and has been accounted for under the purchase method of
accounting. More detailed discussions of these operations follow in the
segment highlights as well as the notes to financial statements.

Year ended December 31, 1999, compared to year ended December 31, 1998

Consolidated gross sales totaled $370.1 million, a 16.8% increase from 1998.
This increase was largely driven by increased gross premium writings of $48.5
million, 16.7% more than in the prior year. Consolidated revenue for 1999 was
$225.8 million, up 34.3% from the previous year. This increase was fueled by
increased writings and the implementation of a combined casualty reinsurance
arrangement, which resulted in larger net retentions of premium.

Comprehensive earnings fell to $20.9 million in 1999 compared to $51.8
million last year, reflecting the impact of the -1.0% total return on the
equity portfolio. Significantly below its average return of more than 17%
since 1982, the equity portfolio's return was diminished by the effect of
rising interest rates on its financial and utility sectors as well as a
general underperformance by value stocks. Despite this aberration, the
Company remains committed to its investment strategy, which management
believes will maximize value for shareholders in the future as it has done
historically, according to the following chart:

As this chart indicates, comprehensive earnings per share for the last five
years exceeded reported net earnings by 66.0% on a diluted basis.

RLI Insurance Group

Gross written premiums in 1999 were $339.6 million, compared to $291.1
million in 1998. While all three insurance segments' premiums increased
nicely, the casualty segment led the way with writings of $35.2 million, or
23.7% over 1998. The Group's pretax underwriting earnings for 1999 were $17.1
million, a 2.1% increase from the $16.8 million reported in 1998. This growth
was related to the higher volume of business despite a slightly higher GAAP
combined ratio (91.2 compared to 88.2 last year).

The Company's property segment improved gross written premiums by 9.8%,
reaching $124.8 million in 1999, compared to $113.6 million in 1998. This
growth was fueled by fire premiums, which increased 33.8%, as well as added
production from new product lines. These increases offset the 7.7% decline in
difference in conditions premiums from the prior year. The property segment
contributed most of the Group's pretax profits, generating $17.1 million in
1999, compared to $19.8 million in 1998. The pressure on profitability came
as a result of an increase in fire business, which has an inherently higher
loss ratio than difference in conditions business. Still, this segment
achieved an enviable GAAP combined ratio of 66.8, up slightly from 62.2 in
the prior year.

Casualty gross written premiums improved 23.7% from 1998, finishing at $183.9
million. This increase was the result of advances in virtually every casualty
product line, led by the transportation line at $12.6 million and
commercial/personal umbrella at $12.0 million. The GAAP combined ratio for
the casualty segment was 101.9, compared to 103.2 in 1998. The new combined
casualty reinsurance contract, implemented at the start of the year, resulted
in an assumption of less exposure per risk. It also increased the retention
of premiums and eliminated reinsurance commissions associated with this
business. The combined ratio improvement complements management's belief that
loss reserves for this segment will be adequate and investment income derived
from reserved funds will provide significant future earnings potential.

The surety segment gross written premiums increased to $30.9 million, a 7.4%
improvement over 1998. This was the direct impact of the Underwriters
Indemnity acquisition, which contributed $7.3 million in gross written
premiums, and helped to offset writings lost from the Company's
disassociation with a particular contract surety producer late in 1998. The
segment's combined ratio came in at 90.5, compared to 103.9 in 1998. The
prior year included a charge of $2.6 million related to unfavorable loss
development from the same discontinued contract surety book. The
Underwriter's Indemnity book contributed to underwriting profits with a
combined ratio below 90, despite some start-up costs associated with the
transition.

Investment Income

Net dividend and interest income increased by 8.7% during 1999 due to
increased cash flow allocated to investments and the acquisition of
Underwriters Indemnity Holdings. On an after-tax basis, investment income
increased by 9.1%. The Company realized $4.5 million in capital gains in
1999, compared to $1.9 million in 1998. Operating cash flows were $58.4
million in 1999. Most cash flows in excess of current needs were used to fund
the stock repurchase program and purchase fixed income securities, which
continue to be comprised primarily of high-grade, tax-exempt, U.S. government
and agency issues. Equity purchases continue to be in large-cap, value
investments with attractive dividend yields.

</TABLE>

Although overall yields in the fixed income markets increased during 1999,
the yields on the portfolio's taxable side were relatively unchanged from
last year. Tax-exempt yields actually fell due to increased call activity on
certain higher-yielding issues early in the year. As the year progressed,
fixed income purchases were being made in both the taxable and tax-exempt
sectors, depending upon the available yields at the time of purchase.

The Company's investment results for the last five years are shown in the
following table:

Interest and General Corporate Expense

Interest expense on debt was $4.1 million in 1999, up from $2.3 million in
1998. This increase was the result of the Company's financing associated with
the Underwriters Indemnity acquisition. General corporate expenses fell to
$2.1 million compared to $3.9 million in 1998 due to executive compensation
that was not earned under the Market Value Potential program.

Income Taxes

The Company's effective tax rates for 1999 and 1998 were 26.9% and 25.1%,
respectively. Effective rates are dependent upon components of pretax
earnings and the related tax effects. Much of the rate increase was due to
the amortization of goodwill associated with the UIH acquisition, which is
not deductible for federal income tax purposes. The Company's pretax earnings
included $15.7 million of investment income in 1999 that is wholly or
partially exempt from federal income tax, compared to $14.3 million in 1998.

Investee Earnings

The Company maintains a 44% interest in the earnings of Maui Jim, Inc.,
primarily a manufacturer of high-quality polarized sunglasses. In 1999, the
Company recorded $1.6 million in earnings compared to $1.3 million in 1998.
Sales for Maui Jim grew 35% in 1999 on the strength of increased
international sunglass marketing efforts. Profit margins declined slightly in
1999 as the cost of goods sold was unfavorably impacted by the dollar's
performance against the yen.

Market Risk Disclosure

Market risk is a general term describing the potential economic loss
associated with adverse changes in the fair market value of financial
instruments. Management of market risk is a critical component of the
Company's investment decisions and objectives. The Company manages its
exposure to market risk by using the following tools:

1.   Continually monitoring the fair market value of all financial assets;
2.   Changing the character of future investment purchases as needed, and;
3.   Maintaining a balance between existing asset and liability portfolios.

The Company's primary risk exposures are to changes in interest rates and
equity prices, as it had no derivative or foreign exchange risk as of
December 31, 1999.

Interest Rate Risk

The Company's primary exposure to interest rate risk is with its fixed income
investment portfolio and outstanding short-term debt instruments.

Modified duration analysis is used to measure the sensitivity of the fixed
income portfolio to changes in interest rates, providing a measure of price
volatility. The Company attempts to minimize


                                       18


<PAGE>


interest rate risk by matching the duration of its assets to that of its
liabilities. The Company limits the financial statement impact of changes in
interest rates by designating a majority of the fixed income holdings as
held-to-maturity. As of December 31, 1999, the Company had classified 86% of
its fixed income portfolio as held-to-maturity. The balance of the Company's
fixed income portfolio is classified as either available-for-sale or trading
(see note 2).

Interest rate risk could also affect the Company's income statement due to
its impact on interest expense. The Company's debt obligations are short-term
in nature, with no long-term debt outstanding as of December 31, 1999. As a
result, the Company assumes interest rate risk in its ability to refinance
these short-term debt obligations. Any rise in interest rates will cause
interest expense to increase, assuming debt is maintained at current levels.

Equity Price Risk

Equity price risk is the potential that the Company will incur economic loss
due to a decline in common stock prices. Beta analysis is used to measure the
sensitivity of the Company's equity portfolio to changes in the value of the
S&P 500 index (an index representative of the broad equity market). As
measured from December 31, 1981, to December 31, 1999, the Company's equity
portfolio has a beta of approximately 0.67 in comparison to the S&P 500. This
low beta statistic reflects the Company's long-term emphasis on maintaining a
conservative, value-oriented, dividend-driven investment philosophy for its
equity portfolio. Historically, dividend-paying common stocks have
demonstrated superior down-market performance characteristics.

Additional risk management techniques include:
1. Restricting individual security weightings to no more than 3% of the equity
   portfolio's market value, and

2. Reducing exposure to sector risk by limiting the market value to be
   invested in any one industry sector to 25% of the equity portfolio.

Equity securities are classified as available-for-sale, with unrealized gains
and losses excluded from net earnings, but recorded as a component of
comprehensive earnings and shareholders' equity, net of deferred income taxes.

Sensitivity Analysis

The following tables detail information on the market risk exposure for the
Company's financial instruments as of December 31, 1999. Listed on each table
is year-end market value for the Company's assets and the expected reduction
in market value, given the stated hypothetical events. This sensitivity
analysis assumes that the composition of the Company's assets remains
constant over the period being measured and that interest rate changes are
reflected uniformly across the yield curve. The analysis does not consider
any action the Company would undertake in response to changes in market
conditions. For purposes of this disclosure, securities are divided into two
categories: those held for trading purposes and those held for nontrading
purposes. The examples given are not predictions of future market events, but
rather illustrations of the effect such events may have on the market value
of the Company's investment portfolio.

As of December 31, 1999, the Company's fixed income portfolio had a market
value of $338.5 million. This sensitivity analysis uses scenarios of interest
rates increasing 100 and 200 basis points from their December 31, 1999,
levels, with all other variables held constant. Such scenarios would result
in decreases in the market value of the fixed income portfolio of $14.2
million and $27.8 million, respectively. Due to the Company's use of the
held-to-maturity designation for a majority of the fixed income portfolio,
the balance sheet impact of these scenarios would be much lower. The income
statement would be affected only by holdings designated as trading.

As of December 31, 1999, the Company's equity portfolio had a market value of
$284.6 million. This base sensitivity analysis uses market scenarios of the
S&P 500 index declining 10 percent and 20 percent. These scenarios would
result in approximate decreases in the market value of the equity portfolio
of $19.1 million and $38.1 million, respectively. As the Company designates
all common stocks as available-for-sale, these market value declines would
impact the Company's balance sheet.

Counter to the base scenarios shown in Tables 1 and 2, Tables 3 and 4
quantify the opposite impact. Under the assumptions of falling interest rates
and an increasing S&P 500 index, the market value of the Company's assets
will increase from their present levels by the indicated amounts.

The income statement will also be affected by interest expense. As of
December 31, 1999, the Company had $78.4 million in short-term debt
obligations. Assuming this debt level remains constant, a hypothetical
100-basis-point increase in interest rates would increase the Company's
annual pretax interest expense by $0.8 million and a 200-basis-point increase
would increase annual pretax interest expense by $1.6 million. Conversely,
falling interest rates would result in equivalent reductions in interest
expense. These numbers are not included in the previous tables.

Outlook for 2000

In 2000, the Company will continue to pursue profitable opportunities for
top-line growth. While some markets show signs of hardening, there is a
continued pursuit of growth through such avenues as the addition of
underwriting talent in certain product lines, strategic alliances with
producers on existing products, or through acquisition. The materiality or
viability of future ventures or products is not known at this time. Specific
details regarding events in the Group's various business segments follow.

Property

The Company expects some leveling of difference in conditions premiums in
2000 despite a continued soft market. The focus on exposure management will
remain as innovative reinsurance arrangements are continually evaluated and
developed.

The Company's fire book of business should continue to grow as new
initiatives related to international and construction lines were begun in the
fall of 1999. Management intends to significantly focus on the development of
these lines.

                                       20


<PAGE>


Casualty

Several initiatives launched over the last two years, coupled with market
firming in select lines, continue to generate substantial revenue. Management
is confident that these initiatives involving product lines such as
commercial umbrella, general liability, executive products, and commercial
auto will produce satisfactory growth results into the near future.
Management's priority in this segment will be the development of the program
product line and the continued expansion of e-commerce.

Surety

Gross written premium increases are anticipated as the Company's contract
surety business is expanded into new geographic areas. A new branch office in
New York, established in mid-1999, is expected to drive this expansion in
2000. Additionally, cross-selling opportunities between the existing
miscellaneous and contract lines with the acquired energy-related operation
will also help to increase writings.

Capital Management

In July 1997, the Company implemented a 1.8 million (2.25 million, adjusted
for the June 1998 5-for-4 stock split) share common stock repurchase program.
In 1999, the Company repurchased 546,476 shares at a total cost of $18.2
million. Including 1998 and 1997, 1,895,879 shares were purchased at a total
cost of $66.5 million. Approximately 354,000 shares remain authorized for
repurchase at year-end 1999. It is anticipated that the program will continue
as market conditions and the Company's capital requirements warrant.

The repurchase program has been funded by the use of the Company's operating
cash flow, line of credit facility, and reverse repurchase agreements. It is
anticipated that future repurchases will be funded in a similar fashion.
Depending upon the Company's capital needs and prevailing market conditions,
the Company may issue a longer-term debt instrument and repay the outstanding
short-term debt.

In the fourth quarter of 1999, RLI declared a cash dividend to be paid in
January 2000 of $0.14 per share, representing the 94th consecutive dividend
payment for the Company. Since the inception of cash dividends in 1976, the
Company has increased the annual dividend every year. In its annual "Handbook
of Dividend Achievers," Moody's ranks RLI 189th out of 10,000 U.S. public
companies in dividend growth over the last decade. No changes in the
Company's dividend policy are anticipated in 2000.

Year ended December 31, 1998, compared to year ended December 31, 1997

Consolidated gross sales totaled $316.9 million, a 3.4% increase from 1997.
Consolidated revenue for 1998 was $168.1 million, down 0.8% from the previous
year. Revenue was relatively flat due to a decrease in net realized
investment gains of 37.9% as well as a 2.5% decline in net investment income.

RLI Insurance Group

Gross written premiums in 1998 were $291.1 million, compared to $278.8
million in 1997. This modest increase reflected the Company's firm commitment
to sound underwriting practices during an ongoing period of difficult pricing
and market conditions in certain lines. The Group's pretax underwriting
earnings for 1998 were $16.8 million, a 10.5% decrease from the $18.8 million
reported in 1997. This decline can be attributed to losses from Hurricane
Georges of $1.1 million and reserve strengthening of $2.6 million on the
surety line, both third quarter events.

The Company's property segment gross written premiums were lower in 1998, at
$113.6 million, compared to $139.5 million in 1997. Nonrecurring premiums
associated with the acquisition of the Hawaii residential insurance business
in March of 1997 accounted for $10.7 million of this decline. While fire
premiums were flat, difference in conditions premiums were down 19.1% from
1997. This decrease can be attributed to rate reductions on these lines of
business while the Company continues to focus on controlling its total
exposure to catastrophe risks.

                                       21

The property segment contributed the largest share of the Group's pretax
profits, generating $19.8 million in 1998, compared to $21.4 million in 1997.
These results were reflected in the property segment GAAP combined ratio of
62.1 for 1998, compared to 65.5 in 1997. Despite the drop in the combined
ratio, Group profits decreased slightly due to $1.1 million in Hurricane
Georges losses as well as a decline in revenue associated with Hawaii
residential insurance.

Casualty gross written premiums improved 31.0% from 1997, reaching $148.7
million in 1998. This overall increase was the result of gains in the
following products: commercial umbrella -- $19.3 million; transportation --
$16.1 million; and general liability -- $3.6 million. The GAAP combined ratio
for the casualty segment was 103.2, compared to 104.6 in 1997. This resulted
from premium increases in the more profitable lines. Despite the lower ratio
in 1998, management believes that loss reserves for this segment will be
adequate and the investment income derived from reserved funds will provide
significant future earnings potential.

The surety segment continued a trend of solid growth as gross written
premiums increased to $28.8 million, which was an 11.5% improvement over
1997. The segment's combined ratio of 103.9 included a charge of $2.6 million
related to unfavorable loss development from one specific contract surety
producer. This particular book of business constituted only 8% of the total
surety book. Excluding this adjustment, the combined ratio for the year would
have fallen to 89.7, compared to 95.4 in 1997. Contributing to this decline
was an improved expense ratio, which dropped to 67.7 in 1998, from 73.8 in
1997. Increased premium volumes paid back earlier infrastructure investments.

Investment Income

Net dividend and interest income decreased by 2.5% during 1998. Despite the
growth in invested assets during the year, a focus on investing new cash flow
in tax-exempt securities, as well as the general downturn in interest rates,
caused the decline. On an after-tax basis, investment income actually
increased slightly (0.3%). The Company realized $1.9 million in capital gains
in 1998, compared to $3.0 million in 1997. Operating cash flows were $23.6
million in 1998. All cash flows in excess of current needs were used to fund
the stock repurchase program and purchase both fixed income and equity
securities.

Overall yields continued to decline during 1998, reflecting the general trend
in the fixed income markets. At year end, the yields on the tax-exempt side
were relatively unchanged from last year, while taxable yields fell rather
significantly. As a result, the after-tax spread between these securities has
widened, making the tax-exempt selections increasingly more attractive. Given
the Company's tax position, the majority of fixed income purchases were made
in this sector.

Interest and General Corporate Expense

Interest expense on debt was $2.3 million in 1998, up from $1.5 million in
1997. This increase was largely the result of the Company's increased use of
short-term borrowings to finance the stock repurchase program. General
corporate expenses decreased 6.2% in 1998 as a result of lower executive
compensation costs relating to the Market Value Potential program.

Income Taxes

The Company's effective tax rates for 1998 and 1997 were 25.1% and 27.3%,
respectively. Effective rates are dependent upon components of pretax
earnings and the related tax effects. The Company's pretax earnings included
$14.3 million of investment income in 1998 that is wholly or partially exempt
from federal income tax, compared to $12.5 million in 1997.

Investee Earnings

The Company maintains a 44% interest in the earnings of Maui Jim, Inc.,
primarily a manufacturer of high-quality polarized sunglasses. In 1998, the
Company recorded $1.3 million in earnings compared to $951,000 in 1997. Sales
for Maui Jim grew 50% in 1998 on the strength of increased sunglass marketing
efforts in several international territories. Profit margins also improved in
1998 as the cost of goods sold was favorably impacted by the dollar's
performance against the yen.

Accounting Standards

In June 1998, the FASB issued Statement No. 133, "Accounting for Derivative
Instruments and Hedging Activities" (Statement 133). Statement 133 addresses
the accounting for and disclosure of derivative instruments, including
certain derivative instruments embedded in other contracts, and hedging
activities. This Statement standardizes the accounting for derivative
instruments by requiring that an entity recognize those items as assets or
liabilities in the statement of financial position and measure them at fair
value. This Statement, as amended by FASB Statement No. 137, is effective for
all fiscal quarters of fiscal years beginning after June 15, 2000. Although
the Company does not currently invest in derivative instruments, this
recently issued Statement is under evaluation.

Legislation

State Regulation

As an insurance holding company, RLI Corp., as well as its insurance
subsidiaries, are subject to regulation by the states in which the insurance
subsidiaries are domiciled or transact business. Holding company registration
in each insurer's state of domicile requires reporting to the state
regulatory authority the financial, operational and management data of the
insurers within the holding company 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
regulators is required prior to the consummation of certain transactions
affecting insurance subsidiaries of the holding company system.

Other regulations 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.
Regulations designed to ensure financial solvency of insurers and to require
fair and adequate treatment and service for policyholders are enforced by
filing, reporting and examination requirements. Market oversight is conducted
by monitoring trade practices, approving policy forms, licensing of agents
and brokers, and requiring fair and equitable premiums and commission rates.
Financial solvency is monitored by minimum reserve and capital requirements,
periodic reporting procedures (annually, quarterly, or more frequently if
necessary), and periodic examinations.

The quarterly and annual financial reports to the states utilize accounting
principles which are different from the generally accepted accounting
principles that show the business as a going concern. The statutory
accounting principles used by regulators, in keeping with the intent to
assure policyholder protection, are generally based on a liquidation concept.
The National Association of Insurance Commissioners (NAIC) has recently
developed a codified version of these statutory accounting principles, and
its deployment in the near future will foster more consistency among the
states for accounting guidelines and reporting.

State 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 to operate in the state through a
corporation. In a few states, licenses are issued only to individual
residents.

Commercial Lines Deregulation -- The NAIC and several state legislatures have
taken up the issue of commercial lines deregulation in an attempt to
streamline specific areas of insurance regulation. A growing contingent in
the regulatory community has acknowledged that some regulatory procedures and
practices may be cumbersome and inappropriate for commercial buyers of
insurance. Specifically, the large, sophisticated, multi-state or
multinational businesses that employ their own teams of risk managers to
evaluate, reduce and finance their loss exposures are less likely to need the
form and rate protections that regulators provide consumers and small to
medium business endeavors. And, while these large businesses may receive some
benefit from the state financial regulation of licensed insurers, it has long
been acknowledged that they do not need the protections addressed by the
barriers to the surplus lines market and other nontraditional markets.
Indisputably, deregulation of the licensed market will have an impact on the
surplus lines insurance carriers, which have been free from form and rate
requirements.

Use of Credit Reports in Underwriting -- Gains in access to electronic
commerce, and the means to gather information more rapidly, have spurred
regulators to take a second look at the use of consumer credit reports in
underwriting and rate making. In some states, regulators charged with
protecting insurance consumers from unfair trade practices are concerned that
some consumers' risks may be underwritten based solely on their credit
standing, and have sought to strengthen their laws and regulations to address
this. This trend comes on the heels of Congress' retooling of the Fair Credit
Reporting Act in 1997, which specifically addresses this issue, and permits
the use of consumer credit reports in underwriting. The issue of federal
preemption of state action in this arena has not been judicially addressed.

Federal Regulation

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 federal preemption of
state auto liability laws, tax reform measures, product liability and
electronic commerce. The Company is also monitoring the following federal
proposals:

Natural Disaster Act -- Recent natural disasters including Atlantic Coast
hurricanes, continue to fuel concern regarding the best way to provide
affordable insurance coverage for such events. Congress has yet to pass
legislation, but proposals to set up a system for federal relief to the
industry continue to be discussed. Two Initiatives, "The Natural Disaster
Protection and Insurance Act of 1997" (S.1361), and "The Homeowners Insurance
Availability Act

                                       23


<PAGE>


of 1997" (H.R. 21), focus on excess federal reinsurance. In 1999, both the
House and Senate introduced versions of the "Policyholder Disaster Protection
Act," which would permit insurers to build tax deferred catastrophe reserves.
The Company will continue to monitor the progress of this issue.

Financial Services Modernization -- The Gramm-Leach-Bliley Act was signed
into law by President Clinton on November 12, 1999. The principal focus of
the Act is to facilitate affiliations among banks, securities firms and
insurance companies. The Act amends the Federal Bank Holding Company Act by
creating a new category of bank holding company known as a "financial holding
company" to engage in activities that are "financial in nature," such as
securities and insurance. The Act repealed the Glass-Steagall Act, which
prohibited a Federal Reserve System member bank from being affiliated with a
securities firm; repealed the Garn-St. Germain Act, which prohibited a bank
holding company and its subsidiaries from selling or underwriting insurance;
and repealed the Federal Bank Holding Company Act provisions that prohibited
a director, officer or employee of a securities firm from serving as a
director, officer or employee of a bank.

Liquidity and Capital Resources

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

The Company maintains a $30.0 million revolving line of credit with one
financial institution. The facility has a three-year term that expires on
December 31, 2001. At December 31, 1999, the Company had $19.6 million in
outstanding debt from this facility. Additionally, the Company was party to
five reverse repurchase transactions totaling $58.8 million. 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 program with Zurich Reinsurance NA (Zurich Re). The program,
called Catastrophe Equity Puts (CatEPutsSM), augments the Company's
traditional reinsurance by integrating its loss financing needs with a
pre-negotiated sale of securities linked to exchange-traded shares. For a
more detailed description of CatEPuts, see note 5.

During 1999, the Company generated net operating cash flow of $58.4 million,
which was added to the Company's investment portfolio and used to repurchase
shares of the Company's stock. Financing activities included the borrowing of
$42.8 million in reverse repurchase agreements that were used, in part, to
finance the January acquisition of Underwriters Indemnity Holdings.

The Company's fixed-income portfolio continues to be biased toward U.S.
government and agency securities due to their high liquidity 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. Most of the Company's fixed-income portfolio is noncallable.

The Company follows a program of matching assets to anticipated liabilities
to ensure its ability to hold securities until maturity. Anticipated
liabilities are factored against ultimate payout patterns and the resulting
payout streams are funded with the purchase of fixed-income securities of
like maturity. Management believes that both liquidity and interest rate risk
can be minimized by such asset/liability matching.

The Company currently classifies approximately 86% of the securities in its
fixed-income portfolio as held-to-maturity, meaning they are carried at
amortized cost and are intended to be held until their contractual maturity.
Smaller portions of the fixed-income portfolio are classified as
available-for-sale (12%) or trading (2%) and are carried at fair market
value. As of December 31, 1999, the Company maintained $48.3 million in
fixed-income securities within the available-for-sale and trading
classifications. 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 address potential future changes in the
Company's asset/liability structure.

The Company's equity portfolio decreased by $11.9 million during 1999, to
$284.6 million. The Company had net sales during the year of $2.8 million of
equities, with a pretax portfolio depreciation of $15.3 million. Capital
gains of $4.9 million on this portfolio were realized during the year. The
securities within the equity portfolio remain invested in large-cap issues
with strong dividend performance. The strategy remains one of value
investing, with security selection taking precedence over market timing. A
buy-and-hold strategy is used, minimizing both transactional costs and taxes.

The National Association of Insurance Commissioners (NAIC) continues its work
on developing a model investment law.

                                       24

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.

Other Matters

The Year 2000 (Y2K) issue is a result of computerized systems, including both
hardware and software systems, using a two-digit format, as opposed to four
digits, to indicate the year in the date field. Such computer systems may be
unable to interpret dates beyond the year 1999, which could cause a system
failure or other computer errors, leading to disruptions in operations.

RLI had identified three major areas determined to be critical for successful
Y2K compliance: (1) accounting and premium processing systems, (2) terms and
conditions of existing insurance contracts, and (3) third-party
relationships. The Company has successfully addressed software and hardware
system issues associated with Y2K through a five-phase program that began in
August of 1997 and was completed in January of 2000.

RLI's offices were closed for the New Year's holiday beginning Friday,
December 31, 1999, through Sunday, January 2, 2000. During this time, the
Company secured systems and data networks through data backups, controlled
shutdowns and verification of system applications and data following Y2K
rollover. A number of activities were undertaken to minimize the potential
impact of Y2K issues on RLI's ability to provide quality service to its
customers, business partners, state regulators and employees.

The computer systems environment was returned to operation on Saturday
morning January 1, 2000. Preliminary testing of operating systems, networks,
communications and primary applications was without problems or issues. On
Sunday, January 2, 2000, effort was dedicated to user and development testing
of applications on the Local Area Networks, P390 and AS/400 systems.
Additionally, RLI branch employees provided support to each remote office to
bring networks and related equipment online and conducted network and
application testing.

The Company controlled and monitored the entry of information into mission
critical systems on January 3 and 4, 2000. This period was used to verify
input, calculations and output of data into financial and processing systems.
To date, RLI has not experienced production issues related to Y2K in any of
the primary or supporting computer systems. RLI continued to monitor data and
system reports through the first quarter for irregularities that may be
caused by Year 2000.

Since 1997, the Company incurred approximately $1.5 million of direct expense
to complete changes and modifications to the business environment for Y2K
compliance. The effort required approximately 30,000 hours of technical staff
effort and changes to systems representing 13.5 million lines of code. Actual
Y2K expenses have been within acceptable ranges of those originally
forecasted. Variations from the original budgets were due to network and
personal computer equipment found to be non-Y2K compliant during mid-1999.
The Company expects to incur a limited amount of additional operational
expense for the remainder of 2000 to monitor and support final Y2K efforts.

Various state insurance departments continue to request and inquire on the
status of the Company's Y2K efforts. The Company received a favorable Y2K
report from the State of Illinois Department of Insurance in September of
1999.

The types of insurance that may be the subject of claims arising from Y2K
losses include property, directors & officers liability, miscellaneous
professional liability, and other casualty. Although uncertainty exists with
respect to legal interpretations of Y2K liability, it is anticipated that if
Y2K claims are received, the majority will stem from director & officers and
miscellaneous professional liability policies, in terms of both frequency and
severity. The Company formulated a Y2K questionnaire to be completed at the
time of initial policy application and renewal. Each application is
individually underwritten, and responses on the Y2K questionnaire are a
component of the underwriter's determination whether to offer coverage and if
so, to what extent. A Y2K exclusion has been drafted and is available for
underwriters' use if needed.

Additionally, a Y2K team of underwriters and claims personnel have been
assembled to prepare for the proper handling of Y2K claims. All claims are
handled on an individual basis in accordance with policy terms and
conditions. The Company has developed an insurance coverage position
statement that is sent to inquiries requesting information regarding policy
provisions.

The Company's executive management has placed emphasis on monitoring
potential issues associated with Y2K and as of this date the Company has not
experienced related problems.

A comprehensive Year 2000 Disclosure is clearly posted on the Company's
Internet site (www.rlicorp.com) and updated on a regular basis to provide
status information for insureds, producers, shareholders and prospective
investors. In addition, regular reports will continue to be prepared for SEC
reporting, insurance regulators, internal management and the board of
directors pertaining to Y2K efforts.

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 four 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 surplus lines insurance
in all 50 states, the District of Columbia, Puerto Rico, the Virgin Islands and
Guam. Underwriters Indemnity Company (UIC), a subsidiary of RLI Insurance
Company, writes multiple lines of insurance on an admitted basis in 23 states
and the District of Columbia. UIC writes surplus lines insurance in an
additional 12 states. Planet Indemnity Company (PIC), a subsidiary of UIC,
writes multiple lines of insurance on an admitted basis in seven states. PIC
writes surplus lines insurance in an additional 16 states and the District of
Columbia.

     B. PRINCIPLES OF CONSOLIDATION AND BASIS OF PRESENTATION: The accompanying
consolidated financial statements were prepared in conformity with generally
accepted accounting principles (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. Certain reclassifications were made to the prior years' financial
statements to conform with the classifications used in 1999.

     In January 1999, RLI Insurance Company acquired Underwriters Indemnity
Holdings, Inc. (UIH), located in Houston, Texas. UIH specializes in the
marketing and underwriting of surety products for oil, gas, mining and other
energy-related exposures.

     RLI paid $40.7 million in cash in exchange for all outstanding shares of
UIH. Included in the transaction were both of UIH's insurance operating
subsidiaries, Underwriters Indemnity Company and Planet Indemnity Company.
The transaction was financed through short-term borrowings and has been
accounted for under the purchase method of accounting. See note 11 for
further discussion and related disclosures.

     In January 1997, the Company paid $3.7 million for an additional 10%
ownership interest in Maui Jim, Inc., bringing the Company's total minority
interest in Maui Jim, Inc. to 44%.

     C. INVESTMENTS: In compliance with FASB Statement 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 86% 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
2% 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 12% 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. 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.

      D. 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.

                                       34


<PAGE>


      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. No
charges occurred in 1997, 1998 or 1999. The Company believes that current
reserve levels for uncollectible reinsurance are sufficient to cover the
related exposure.

      E. UNPAID LOSSES AND SETTLEMENT EXPENSES: The liability for unpaid
losses and settlement expenses represents estimates of amounts needed to pay
reported and unreported claims and related expenses. The estimates are based
on certain actuarial and other assumptions related to the ultimate cost to
settle such claims. Such assumptions are subject to occasional changes due to
evolving economic, social and political conditions. All estimates are
periodically reviewed and, as experience develops and new information becomes
known, the reserves are adjusted as necessary. Such adjustments are reflected
in the results of operations in the period in which they are determined. Due
to the inherent uncertainty in estimating reserves for losses and settlement
expenses, there can be no assurance that the ultimate liability will not
exceed recorded amounts, 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, 1999, are
adequate to meet its future obligations.

      F. 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.

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

      H. 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.

     I. INTANGIBLE ASSETS: Goodwill is amortized on a straight-line basis for
financial statement purposes over periods ranging from 10 to 20 years.

     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: Pursuant to disclosure requirements contained in
FASB Statement 128, the following represents a reconciliation of the numerator
and denominator of the basic and diluted EPS computations contained in the
financial statements. Conversion of the Company's $46.0 million convertible
debenture occurred in July 1997. See note 4 for further discussion and related
disclosures.

</TABLE>

      L. COMPREHENSIVE EARNINGS: FASB Statement No. 130, "Reporting
Comprehensive Income," was adopted by the Company in 1997. 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 components of comprehensive earnings on a net
basis in the income statement, the Company has used a 35% tax rate.

                                       35


<PAGE>

Other comprehensive income (loss), as shown, is net of tax expense (benefit)
of ($5.7 million), $12.7 million, and $19.5 million, respectively, for 1999,
1998, and 1997.

     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 independent pricing services or 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 shares with an exercise price equal to 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 the 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 (51.6% of gross
property premiums written during 1999). 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 as deemed necessary.
Other estimates such as the recoverability of reinsurance balances, deferred tax
assets and deferred policy acquisition costs are regularly monitored, evaluated,
and adjusted. Although recorded estimates are supported by actuarial
computations

                                       36


<PAGE>


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 various programs designed to ensure policyholder
indemnification. 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 regularly
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, and that
its capital levels are sufficient to support the level of risk inherent in its
operations.

</TABLE>

      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, 1999, the net unrealized appreciation of
available-for-sale fixed maturities and equity securities totaled $99.8
million. This amount was net of deferred taxes of $53.4 million. At December
31, 1998, the net unrealized appreciation of available-for-sale fixed
maturities and equity securities totaled $110.4 million. This amount is net
of deferred taxes of $59.1 million.

      The Company is party to a securities lending program where-by
fixed-income securities are loaned to third parties, primarily major
brokerage firms. As of December 31, 1999 and 1998, fixed maturities with a
fair value of $13.1 million and $25.1 million, respectively, were loaned.
Agreements with custodian banks facilitating such lending generally require
102% of the value of the loaned securities to be separately maintained as
collateral for each loan. Pursuant to FASB Statements 125 and 127, an
invested asset and a corresponding liability have been recognized for this
collateral amount. 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 $20.6 million at December 31, 1999, were on deposit with either
regulatory authorities or banks. Additionally, the Company has certain fixed
maturities held in trust amounting to $7.7 million at December 31, 1999.
These funds cover net premiums, losses, and expenses related to a property
and casualty insurance program.

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 semiannually. On
June 20, 1997, the Company announced that it was calling for redemption all
convertible debentures. The entire issue was 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 48.0769 shares of RLI common
stock for each $1,000 principal amount of convertible debt. On July 22, 1997,
the entire $46.0 million was converted into RLI common stock. This conversion
created an additional 2,211,499 new shares of RLI common stock.

      The Company continued the use of short-term credit facilities through
reverse repurchase transactions. During 1999, the Company borrowed $42.8 million
in reverse repurchase agreements, in part, to finance the January acquisition of
Underwriters Indemnity Holdings.

      Interest paid on outstanding debt for 1999, 1998, and 1997, amounted to
$3.5 million, $2.3 million, and $2.8 million, respectively.

      The Company maintains a $30.0 million revolving line of credit from one
financial institution. The facility has a three-year term that expires on
December 31, 2001. As of December 31, 1999, the Company had $19.6 million in
outstanding debt from this facility. The weighted-average interest rate on this
line of credit was 5.98% for 1999. Additionally, the Company was party to five
reverse repurchase transactions totaling $58.8 million.

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 $700,000. 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 Zurich Reinsurance NA (Zurich Re). The
program, called Catastrophe Equity Puts (CatEPuts), 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

                                       39


<PAGE>


Company to put up to $50.0 million of its convertible preferred
shares to Zurich 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 began as a multi-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 Zurich Re, then Zurich Re, in turn, has the option to
reinsure certain business written by the Company on a prospective basis. This
agreement is scheduled for renewal at July 1, 2000.

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

      At December 31, 1999, the Company had prepaid reinsurance premiums and
reinsurance recoverables on paid and unpaid losses and settlement expenses with
American Re-Insurance Company and with Transatlantic Reinsurance Company (both
rated A++ "Superior" by A.M. Best Company) that amounted to $66.3 million and
$31.0 million, respectively. 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,
1999. 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).

      During the three years, overall development on prior accident-year loss
and settlement expense reserves was insignificant to recorded loss and
settlement expense reserves.

      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 following table represents inception-to-date paid and unpaid
environmental claims data (including incurred but not reported losses) for the
periods ended 1999, 1998 and 1997:

</TABLE>

      Although the Company's environmental exposure is limited as a result of
entering 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

      The tax effects of temporary differences that give rise to significant
portions of the deferred tax assets and deferred tax liabilities are summarized
in the following table.

      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.

      Income tax expense attributable to income from operations for the years
ended December 31, 1999, 1998, and 1997, differed from the amounts computed by
applying the U.S. federal tax rate of 35% to pretax income from continuing
operations as demonstrated in the following 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 in 1999, 1998, and 1997, amounted
to $13.3 million, $10.6 million, and $11.1 million, respectively.

      The Internal Revenue Service (IRS) has examined the Company's income
tax returns through the tax year ended December 31, 1994. The IRS is not
currently examining any of the Company's income tax returns.

8   EMPLOYEE BENEFITS

PENSION PLAN

      The Company maintains a noncontributory 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 1999, 1998,
and 1997, the Company made the maximum tax deductible contribution allowed,
totaling $448,695, $422,489, 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 financial status of the plan for each of the three years ended
December 31 is illustrated in the following tables:

EMPLOYEE STOCK OWNERSHIP AND BONUS AND INCENTIVE PLANS

The Company has an Employee Stock Ownership Plan (ESOP) and executive
performance incentive plans. The Company evaluates the funding of the latter
plans through Market Value Potential (MVP), which ensures that the interests
of the Company's executives correspond with those of our shareholders.

                                       42


<PAGE>


      MVP requires that the Company generate a return on equity in excess of its
cost of capital before the payment of 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 associates.

      Under the executive performance incentive plans, participants can receive
a maximum of 1% of the excess on an after-tax basis, while officers can receive
a maximum of approximately 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 limits the officer payout in a given year to 50% (60% prior to 1998) of
the combination of bonuses earned in the previous fiscal year plus any unpaid
balance carried forward from prior years. The remaining balance 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.

      The following table illustrates the amount earned, the percentage of MVP
earned, and the subsequent amount paid for each year:

</TABLE>


      In addition to the executive amount paid in 1999, an additional $54,000
was deferred toward Company stock plans as discussed below.

      The Company's ESOP 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.
ESOP-related expenses were $2.9 million in 1999 and 1998 and $2.6 million in
1997. At its December 1999 meeting, the board approved a contribution.
Contributions were authorized in 1998 and 1997, as well.

      During the third quarter of 1998, the Company leveraged the ESOP and
purchased a total of 70,400 shares at an average price of $35.58 per share
($2.5 million) in advance of the actual contribution to the plan in January
1999. There were no additional shares purchased in 1999. As a result of the
1997 ESOP contribution made in January 1998, the ESOP purchased 61,802 shares
on the open market at an average price of $38.54 ($2.4 million). During 1997,
the ESOP purchased 79,801 shares of the Company's common stock on the open
market at an average price of $26.62 ($2.1 million). Shares held by the ESOP
are treated as outstanding in computing the Company's earnings per share. At
December 31, 1998, unearned leveraged shares were not considered outstanding
for calculating earnings per share.

Dividends on earned ESOP shares are passed through to the participants.

DEFERRED COMPENSATION

The Company maintains a Rabbi Trust for deferred compensation plans for
directors, key employees and executive officers through which company shares
are purchased. During 1998, the Emerging Issues Task Force reached its
consensus on issue 97-14 relative to Rabbi Trusts. This prescribed an
accounting treatment whereby the employer stock in the plan is classified and
accounted for in equity, in a manner consistent with the accounting for
treasury stock. This increased the Company's treasury stock by $3.5 million
in 1998. The deferred compensation obligation is classified as an equity
instrument. This treatment was applied prospectively by the Company in 1998.

      The expense associated with funding these plans is recognized through
salary, bonus, and ESOP expenses for key employees and executive officers as
disclosed in prior notes. The expense recognized from the directors deferred
plan was $162,700, $175,900, and $158,600 in 1999, 1998 and 1997,
respectively. In 1999, the Rabbi Trusts purchased 38,837 shares of the
Company's common stock on the open market at an average price of $32.97
($1,280,347). In 1998, the Rabbi Trusts purchased 15,521 shares of the
Company's common stock on the open market at an average price of $37.20
($577,409). In 1997, the Rabbi Trusts purchased 9,679 shares of the Company's
common stock on the open market at an average price of $31.62 ($306,027). At
December 31, 1999, the Trusts' assets were valued at $7.3 million.

STOCK OPTION PLANS

During 1995, the Company adopted and the shareholders approved a tax-favored
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 these plans in accordance with APB
Opinion No. 25, under which no compensation cost is recognized.

                                       43


<PAGE>


      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>
<CAPTION>

(in thousands, except per share data)     1999         1998         1997

Net income:   As reported               $31,451      $28,239       $30,171
              Pro forma                  30,608       27,592        29,789
Diluted EPS:  As reported                 $3.08        $2.65         $2.66
              Pro forma                   $2.99        $2.59         $2.63
</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 as determined
by the Company's board of directors. 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. Full vesting of options granted occurs at the
end of five years.

      Under the Directors' Plan, shares granted do not qualify as tax-favored
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 30,000 shares (3,750
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 1,562,500 shares under the
Incentive Plan and 250,000 shares under the Directors' Plan. Through December
31, 1999, the Company has granted 587,551 options under these plans. Under
both plans, the option exercise price equals the stock's fair market value on
the date of grant.

      A summary of the status of the plans at December 31, 1999, 1998 and
1997, and changes during the years then ended are presented in the following

POST-RETIREMENT BENEFITS OTHER THAN PENSION

     The Company does not provide post-retirement or post-employment benefits
to employees and therefore does not have any liability under FASB Statement No.

or FASB Statement No. 112, "Employers' Accounting for Post-employment
Benefits."

9   STATUTORY INFORMATION AND DIVIDEND RESTRICTIONS

      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 2000 without prior notice or approval is $28.6 million
- -- 10% of RLI Insurance Company's 1999 policyholder surplus. The actual amount
paid to the Company during 1999 was $24.9 million.


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.

      The Company leases regional office facilities and automobiles under
operating leases expiring in various years through 2004. Minimum future
rental payments under noncancellable operating leases are as follows:

11   ACQUISITION

      On January 29, 1999, RLI Insurance Company purchased Underwriters
Indemnity Holdings (UIH) for $40.7 million. The purchase was financed
entirely through short-term debt. UIH is the insurance holding company for
Planet Indemnity Company and Underwriters Indemnity Company. As a
property/casualty insurance group these companies have combined to offer
primarily surety and inland marine coverages on commercial risks relating to
the exploration, drilling, producing and gathering activities of the oil and
gas industry. Also provided to a lesser degree were control of well and
general liability insurance. The genuine value of this

                                       45


<PAGE>


operation was found almost exclusively in the surety operations. The casualty
book was considered incidental to the overall business while the property
business contained deficient premiums to an unknown extent. All property
coverages are being non-renewed in accordance with allowable policy
provisions.

      The acquisition is being accounted for under the purchase method of
accounting for business combinations. RLI Corp.'s 1999 financial statements
include the results of UIH's operations from January 29, 1999, through
December 31, 1999. Accounting guidance derived primarily from APB 16
regarding business combinations dictates that the purchase price be allocated
to the assets acquired less liabilities assumed with any excess being
recorded as goodwill. The allocation of the purchase price results in
goodwill of $32.0 million that will be amortized over 20 years.

      The table below summarizes, on a proforma basis, the Company's
consolidated results of operations as if the purchase of UIH had taken place
as of January 1, 1998.

</TABLE>

      The dilutive effect on pro forma earnings was the result of recognizing
pre-acquisition premium deficiency and reserve strengthening on the property
business. As indicated above, the Company does not intend to pursue this line
of business and consequently, does not anticipate any future earnings impact.

12   INDUSTRY SEGMENT INFORMATION

      The following table summarizes the Company's segment data as specified
by FASB Statement No. 131, "Disclosures about Segments of an Enterprise and
Related Information." As prescribed by the pronouncement, reporting is based
on the internal structure and reporting of information as it is used by
Company management.

      The segments of the property/casualty operations of the Company include
property, casualty and surety. The property segment is comprised of insurance
products providing physical damage coverage for commercial and personal
risks. These risks are exposed to a variety of perils including earthquakes,
fires and hurricanes. Losses are developed in a relatively short period of
time.

      The casualty segment includes liability products where loss and related
settlement expenses must be estimated, as the ultimate disposition of claims
may take several years to fully develop. Policy coverage is more
significantly impacted by evolving legislation and court decisions.

      The surety segment offers a selection of small- and medium-sized
commercial products related to the statutory requirement for bonds on
construction and energy-related projects. The results of this segment are
characterized by relatively low loss ratios. However, expense ratios tend to
be higher due to the high volume of transactions at lower premium levels.

      The investment income segment is the by-product of the interest and
dividend income streams from the Company's investments in fixed-income and
equity securities. Interest and general corporate expenses include the cost
of debt and other director and shareholder relations costs incurred for the
benefit of the corporation, but not attributable to the operations of other
segments. Investee earnings represent the Company's share in Maui Jim, Inc.
earnings. The Company owns approximately 44% of the unconsolidated investee,
which operates in sunglass and optical goods industries.

      The following table provides data on each of the Company's segments as
used by company management. The net earnings of each segment are before
taxes, and include revenues (if applicable), direct product or segment costs
(such as commissions, claims costs, etc.), as well as allocated support costs
from various overhead departments. While depreciation and amortization
charges have been included in these measures via the Company's expense
allocation system, the related assets are not allocated for management use
and, therefore, are not included in this schedule. Goodwill amortization
resulting from the UIH acquisition was allocated entirely to the surety
segment.

(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, 1999 and 1998, 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,
1999. 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, 1999 and 1998, and the results of their
operations and their cash flows for each of the years in the three-year
period ended December 31, 1999, 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 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. As part of its audit of the financial statements, 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, 1999,
the Company's system of internal controls was adequate to accomplish the
objectives described herein.

The audit committee is comprised solely of three 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. The
independent public accountants and the internal auditor have ready access to
the audit committee.

(1) For all periods presented, net operating earnings represent the Company's
    net earnings reduced by after-tax realized gains. For 1993, the financial
    impact of FASB Statement No. 109 has also been deducted in arriving at
    operating earnings.

(2) See note 1.L to the consolidated financial statements.

(3) See note 1.K to the consolidated financial statements.

(4) The statutory combined ratio presented includes the results of UIC and
    PIC only from the date of acquisition, January 29, 1999.

(5) The combined effects of the Northridge Earthquake -- including losses,
    expenses and the reduction in revenue due to the reinstatement of
    reinsurance coverages -- reduced 1994 after-tax earnings by $25.0 million
    ($2.57 per basic share, $2.10 per diluted share) and 1995 after-tax
    earnings by $18.6 million ($1.90 per basic share, $1.54 per diluted
    share).

(6) For 1995, diluted earnings per share on a GAAP basis were
    antidilutive. As such, GAAP diluted and basic earnings per share were
    equal. Diluted comprehensive earnings per share, however, were not
    antidilutive. The number of diluted shares used for this calculation was
    9,619.

(7) Contingent commission income recorded during 1993, from the
    cancellation of a multiple-year, retrospectively-rated reinsurance
    contract, reduced the statutory expense and combined ratio 10.3 points.

(8) Basic and diluted earnings per share include $.18 and $.16 per share,
    respectively, from the initial application of FASB Statement No. 109
    "Accounting for Income Taxes."
