PART I
ITEM 1. BUSINESS

General Description of the Company's Business

W. R. Berkley Corporation (the "Company"), a Delaware corporation, is
an insurance holding company which, through its subsidiaries, presently operates
in all segments of the property casualty insurance business: regional property
casualty insurance; reinsurance; specialty lines of insurance (including excess
and surplus lines and commercial transportation); alternative markets (including
the management of alternative insurance market mechanisms); and international.
The Company was founded on the concept that a group of autonomous regional and
specialty insurance entities could compete effectively in selected markets
within a very large industry. Decentralized control allows each subsidiary or
regional group to respond to local or specialty market conditions while
capitalizing on the effectiveness of centralized investment and reinsurance
management and actuarial, financial and legal staff support.

The Company's regional insurance operations are conducted primarily in
the New England, Mid Atlantic, Midwest and Southern regions of the United
States. Reinsurance, specialty insurance and alternative markets operations are
conducted nationwide. Presently, international operations are conducted
primarily in Argentina and the Philippines.

Net premiums written, as reported on a generally accepted accounting
principles ("GAAP") basis, by the Company's five major insurance industry
segments for the five years ended December 31, 1999 were as follows:

The following sections briefly describe the Company's insurance
segments and subsidiaries. The statutory information contained herein is derived
from that reported to state regulatory authorities in accordance with statutory
accounting practices ("SAP"). The descriptions contain each significant
insurance subsidiary's rating by A.M. Best and Company, Inc. ("A.M. Best"). A.M.
Best's ratings are based upon factors of concern to policyholders, insurance
agents and brokers and are not directed toward the protection of investors. A.M.
Best states: "Best's Ratings reflect [its] opinion as to the relative financial
strength and performance of each insurer in comparison with others, based on
[its] analysis of the information provided to [it]. These ratings are not a
warranty of an insurer's current or future ability to meet its contractual
obligations." A.M. Best reviews its ratings on a periodic basis, and ratings of
the Company's subsidiaries are therefore subject to change.

REGIONAL INSURANCE OPERATIONS

The Company's regional property casualty subsidiaries write standard commercial
and personal lines insurance for such risks as automobiles, homes and
businesses. The Company's regional insurance operations have historically been
conducted through ten principal operating subsidiaries. In 1999, the Company

minimized or eliminated.

are as follows:

REINSURANCE OPERATIONS

The Company's reinsurance operations consist of six operating units,
which specialize in underwriting property, casualty and surety reinsurance on
both a treaty and a facultative basis. The Company's reinsurance operations are
conducted by Signet Star Holdings, Inc. through its subsidiary Signet Star
Reinsurance Company ("Signet Star"). For financial segment reporting purposes,
the results of the alternative market division of Signet Star are included in
the Company's alternative markets segment. Signet Star is rated A by A.M. Best.

The Property Casualty Treaty Division is the largest business unit in
terms of personnel and premiums written. This division of Signet Star is
committed exclusively to the broker market segment of the treaty reinsurance
industry. It functions as a traditional reinsurer in specialty and standard
reinsurance lines. This unit is de-emphasizing commodity lines of business,
which are experiencing intense competition brought on, in part, by excess
capacity.


Facultative ReSources, Inc. ("Fac Re"), an underwriting manager,
specializes in individual certificate and program facultative business. Fac Re's
highly experienced underwriters seek to offset the underwriting and pricing
cycles in the underlying insurance business by developing risk management
solutions and through superior risk selection. Fac Re develops its business
through brokers and on a direct basis where the client does not choose to use an
intermediary.


The Fidelity and Surety Division ("F&S") operates as a lead reinsurer
in a niche market of the property casualty industry where its highly specialized
knowledge and expertise are essential to meet the needs of fidelity and surety
primary writers. Business is marketed principally through brokers as well as
directly to clients not served by intermediaries.


Gemini Insurance Company is an excess and surplus line insurance
company which commenced business in 1997 to provide Signet Star with primary
issuing carrier capability and thereby generate "reverse flow" business. Under
the reverse flow concept, a reinsurer writes primary business through a
subsidiary or affiliated carrier that is then ceded back to the reinsurer. It
operates as an authorized insurance company in the State of Delaware and will
operate nationwide, as necessary legal and regulatory requirements are met, as
an approved excess and surplus line carrier. Gemini is rated A by A.M. Best.


StarNet Insurance Company ("StarNet") was acquired by Signet Star in
1998 to write reverse flow business on an admitted basis. Signet Star will seek
to license StarNet broadly to serve as an adjunct to Gemini to write primary
business on an admitted basis nationwide. StarNet is rated A by A.M. Best.


The Latin American and Caribbean Division was established in 1996 to
write business exclusively in Latin America and the Caribbean. In January 2000,
Signet Star decided to withdraw from this market place, with no new business
being written after February 1, 2000. The Division's net premiums written for
the year ended December 31, 1999 were $21,088,000.

As an admitted company, Admiral Indemnity will compete for certain risks that
might be subject to the commercial lines deregulation enactments (see
"Regulation") as well as other risks which prefer an admitted carrier. Admiral
Indemnity will also continue to write commercial business consisting primarily
of multiple dwelling and restaurant coverages principally in the State of New
York through operations conducted by Clermont Specialty Managers, Ltd., an
underwriting manager which is owned by the Company. Admiral Indemnity is rated A
by A.M. Best (BRIC group rating). Admiral Indemnity's net premiums written for

from approximately 120 agents and brokers who are compensated on a commission
basis. Carolina also writes surety bonds through operations conducted by Monitor

Best. Carolina's net premiums written for the year ended December 31, 1999 were
$82,673,000.

general agents, some of which also provide business to Admiral. A substantial
portion of Nautilus' business is written on a binding authority basis, subject
to certain contractual limitations. Nautilus is rated A by A.M. Best. Nautilus'
net premiums written for the year ended December 31, 1999 were $60,649,000.

Loss and Loss Adjustment Expense Reserves

In the property casualty industry, it is not unusual for significant
periods of time to elapse between the occurrence of an insured loss, the report
of the loss to the insurer and the insurer's payment of that loss. To recognize
liabilities for unpaid losses, insurers establish reserves, which is a balance
sheet account representing estimates of future amounts needed to pay claims and
related expenses with respect to insured events which have occurred. The
Company's loss reserves reflect current estimates of the ultimate cost of
closing outstanding claims; other than its excess workers' compensation ("EWC")
business, as discussed below, the Company does not discount its reserves to
estimated present value for financial reporting purposes.


15
16
In general, when a claim is reported, claims personnel establish a
"case reserve" for the estimated amount of the ultimate payment. The estimate
represents an informed judgment based on general reserving practices and
reflects the experience and knowledge of the claims personnel regarding the
nature and value of the specific type of claim. Reserves are also established on
an aggregate basis which provide for losses incurred but not yet reported to the
insurer, potential inadequacy of case reserves, the estimated expenses of
settling claims, including legal and other fees and general expenses of
administering the claims adjustment process ("LAE"), and a provision for
potentially uncollectible reinsurance. Each insurance subsidiary's net retention
for each line of insurance is taken into consideration in computation of
ultimate losses.

In examining reserve adequacy, several factors are considered,
including historical data, legal developments, changes in social attitudes and
economic conditions, including the effects of inflation. The actuarial process
relies on the basic assumption that past experience, adjusted judgmentally for
the effects of current developments and anticipated trends, is an appropriate
basis for predicting future events. Reserve amounts are necessarily based on
management's informed estimates and judgments using data currently available. As
additional experience and other data become available and are reviewed, these
estimates and judgments are revised. This may result in increases or decreases
to reserves for insured events of prior years. The reserving process implicitly
recognizes the impact of inflation and other factors affecting loss costs by
taking into account changes in historical claim patterns and perceived trends.
There is no precise method to evaluate the impact of any specific factor on the
adequacy of reserves, because the ultimate cost of closing claims is influenced
by numerous factors.

While the methods for establishing the reserves are well tested over
time, some of the major assumptions about anticipated loss emergence patterns
are subject to fluctuation. In particular, high levels of jury verdicts against
insurers, as well as judicial decisions which "re-formulate" policies to expand
coverage to include previously unforeseen theories of liability, e.g., those
regarding pollution and other environmental exposures, have produced
unanticipated claims and increased the difficulty of estimating the loss and
loss adjustment expense reserves provided by the Company.

Due to the nature of EWC business and the long period of time over
which losses are paid in this line of business, the Company discounts its
liabilities for EWC losses and loss expenses. Discounting liabilities for losses
and loss expenses gives recognition to the time value of money set aside to pay
claims in the future and is intended to appropriately match losses and loss
expenses to income earned on investment securities supporting the liabilities.
The expected losses and loss expense payout pattern subject to discounting was
derived from loss payout experience and is supplemented with data compiled by
insurance companies writing workers' compensation on an excess-of-loss basis.
The expected payout pattern has a very long duration because it reflects the
nature of losses which generally penetrate self-insured retention limits
contained in EWC policies. The Company has limited the expected payout duration
to 30 years in order to introduce an additional level of conservatism into the
discounting process. These liabilities have been discounted using "risk-free"
discount rates determined by reference to the U.S. Treasury yield curve weighted
for EWC premium volume to reflect the seasonality of the anticipated duration of
losses associated with such coverages. The average discount rate for accident
years 1999, 1998, 1997, 1996 and 1995 and prior was approximately 5.90% 5.90%,
5.98%, 5.90% and 5.80%, respectively. The aggregate net discount, after
reflecting the effects of ceded reinsurance, is $186,981,000, $186,964,000,
$189,600,000 and $172,415,000 at December 31, 1999, 1998, 1997 and 1996,
respectively.

To date, known pollution and environmental claims at the Company's
insurance company subsidiaries have not had a material impact on the Company's
operations. Environmental claims have not materially impacted the Company
because these subsidiaries generally did not insure the larger industrial
companies which are subject to significant environmental exposures.


16
17
The Company's net reserves for losses and loss adjustment expenses
relating to pollution and environmental claims were $30,944,000 and $33,391,000
at December 31, 1999 and 1998, respectively. The Company's gross reserves for
losses and loss adjustment expenses relating to pollution and environmental
claims were $65,966,000 and $69,283,000 at December 31, 1999 and 1998,
respectively. Net incurred losses and loss expenses for reported pollution and
environmental claims were approximately $1,371,000, $2,227,000 and $79,000 in
1999, 1998 and 1997, respectively. Net paid losses and loss expenses were
approximately $3,819,000, $2,614,000 and $2,175,000 in 1999, 1998 and 1997,
respectively. The estimation of these liabilities is subject to significantly
greater than normal variation and uncertainty because it is difficult to make a
reasonable actuarial estimate of these liabilities due to the absence of a
generally accepted actuarial methodology for these exposures and the potential
affect of significant unresolved legal matters, including coverage issues as
well as the cost of litigating the legal issues. Additionally, the determination
of ultimate damages and the final allocation of such damages to financially
responsible parties are highly uncertain.

reserve balances, on a gross of reinsurance basis (dollars in thousands)(1):

The following table presents the development of net reserves for 1989
through 1999. The top line of the table shows the estimated reserves for unpaid
losses and loss expenses recorded at the balance sheet date for each of the
indicated years. This represents the estimated amount of losses and loss
expenses for claims 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 upper 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 years.


The "cumulative redundancy (deficiency)" represents the aggregate
change in the estimates over all prior years. For example, the 1989 reserves
have developed a $84 million redundancy over ten years. That amount has been
reflected in income over the ten years. The impact on the results of operations
of the past three years of changes in reserve estimates is shown in the
reconciliation tables above.

It should be noted that the table presents a "run off" of balance sheet
reserves, rather than accident or policy year loss development. Therefore, each
amount in the table includes the effects of changes in reserves for all prior
years. For example, assume a claim that occurred in 1989 is reserved for $2,000
as of December 31, 1989. Assuming this claim was settled for $2,300 in 1999, the
$300 deficiency would appear as a deficiency in each year from 1989 through
1998.

Regulation

The Company's insurance subsidiaries are subject to varying degrees of
regulation and supervision in the jurisdictions in which they do business, under
statutes which delegate regulatory, supervisory and administrative powers to
state insurance commissioners. This regulation relates to such matters as the
standards of solvency which must be met and maintained; the licensing of
insurers and their agents; the nature of and limitations on investments;
deposits of securities for the benefit of policyholders; approval of policy
forms and premium rates; periodic examination of the affairs of insurance
companies; annual and other reports required to be filed on the financial
condition of insurers or for other purposes; establishment and maintenance of
reserves for unearned premiums and losses; and requirements regarding numerous
other matters. The Company's property casualty subsidiaries, other than E & S
and reinsurance subsidiaries, must file all rates for personal and commercial
insurance with the insurance department of each state in which they operate. The
Company's E & S and reinsurance subsidiaries generally operate free of rate and
form regulation.

In addition to regulatory supervision of its insurance subsidiaries,
the Company is subject to state statutes governing insurance holding company
systems. Typically, such statutes require the Company periodically to file
information with the state insurance commissioner, including information
concerning its capital structure, ownership, financial condition and general
business operations. Under the terms of applicable state statutes, any person or
entity desiring to purchase more than a specified percentage (commonly 10%) of
the Company's outstanding voting securities would be required to obtain
regulatory approval of the purchase. Under Florida law, which is applicable to
the Company due to its ownership of Carolina, a Florida domiciled insurer, the
acquisition of more than 5% of the Company's capital stock must receive
regulatory approval. Further, state insurance statutes typically place
limitations on the amount of dividends or other distributions payable by
insurance companies in order to protect their solvency. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations-Liquidity and Capital Resources."

During the past several years, various regulatory and legislative
bodies adopted or proposed new laws or regulations to deal with the cyclical
nature of the insurance industry, catastrophic events and their effects on
shortage of capacity and pricing. These regulations, which have not had a
material impact on the Company's operations, include (i) the creation of "market
assistance plans" under which insurers are induced to provide certain coverages,
(ii) restrictions on the ability of insurers to cancel certain policies in
mid-term, (iii) advance notice requirements or limitations imposed for certain
policy non-renewals and (iv) limitations upon or decreases in rates permitted to
be charged. The passage of Proposition 103 in the State of California did not
have a material adverse impact on the Company's operations because the Company's
subsidiaries operated in that State primarily on a non-admitted basis. The
non-admitted market in California, however, has been subjected to increased
levels of regulation. Admiral and Nautilus, both of which derive significant
premiums from California, may be adversely impacted by increased regulation
which causes business to remain in the admitted market. Additionally, a number
of states have adopted and others are considering adopting forms of commercial
lines deregulation laws which, depending upon factors such as the relatively
high amount of premium or revenue of an insured, would permit an insurer to
provide insurance without being subject to rate and/or form filing requirements.

Various state and federal organizations, including Congressional
committees and the National Association of Insurance Commissioners ("NAIC"),
have been conducting reviews into various aspects of the insurance business. The
NAIC has adopted risk based capital ("RBC") requirements that require insurance
companies to calculate and report information under a risk-based formula which
measures statutory capital and surplus needs based on a regulatory definition of
risk in a company's mix of products and its balance sheet. The implementation of
RBC did not affect the operations of the Company's insurance subsidiaries since
all of its subsidiaries have a RBC amount above the authorized control level
RBC, as defined by the NAIC. The NAIC recently completed a process intended to
codify statutory accounting practices for certain insurance enterprises. As a
result of this process, the NAIC will issue a revised statutory accounting
practices and procedures manual, which will be effective January 1, 2001. The
Company has not yet determined the impact that this change will have on the
statutory capital and surplus of its insurance subsidiaries. The NAIC is
considering model laws on commercial lines deregulation. Federal legislation is
being considered which would either abolish or limit the current exemption of
the insurance industry from portions of the antitrust laws, impose direct
federal oversight or federal solvency standards. No assurance can be given that
future legislative or regulatory changes resulting from such activity will not
adversely affect the Company's insurance subsidiaries.



20
21
The Gramm-Leach-Bliley Act, or Financial Services Modernization Act of
1999 (the "Act"), was enacted in 1999, significantly affecting the financial
services industry, including insurance companies, banks and securities firms.
The Act modifies federal law to permit the creation of financial holding
companies ("FHCs"), which, as regulated by the Act, can maintain cross-holdings
in insurance companies, banks and securities firms to an extent not previously
allowed. The Act also permits or facilitates certain types of combinations or
affiliations for FHCs. The Act establishes a functional regulatory scheme under
which state insurance departments will maintain primary regulation over
insurance activities, subject to provisions for certain federal preemptions.

Important provisions of the Act involve requirements for adoption of
(i) multi-state agents' licensing reforms and uniformity requirements and (ii)
privacy protections, giving the states the ability to enact these laws in the
first instance or be preempted. The NAIC is considering adoption of a model law
on privacy. It has also adopted a model law on agents' licensing which has been
enacted or is currently being considered by various state legislatures. It is
not anticipated that the insurance regulatory aspects of the Act will have a
material effect on the operations of the Company.

The Company's insurance subsidiaries are also subject to assessment by
state guaranty funds when an insurer in that jurisdiction has been judicially
declared insolvent and insufficient funds are available from the liquidated
company to pay policyholders and claimants. The protection afforded under a
state's guaranty fund to policyholders of the insolvent insurer varies from
state to state. Generally, all licensed property casualty insurers are
considered to be members of the fund, and assessments are based upon their pro
rata share of direct written premiums. The NAIC Model Post-Assessment Guaranty
Fund Act, which many states have adopted, limits assessments to an insurer to 2%
of its subject premium and permits recoupment of assessments through rate
setting. Likewise, several states (or underwriting organizations of which the
Company's insurance subsidiaries are required to be members) have limited
assessment authority with regard to deficits in certain lines of business. To
date, assessments have not had a material adverse impact on operations.

The Company receives funds from its insurance subsidiaries in the form
of dividends and fees for certain management services. Annual dividends in
excess of maximum amounts prescribed by state statutes ("extraordinary
dividends") may not be paid without the approval of the insurance commissioner
of the state in which an insurance subsidiary is domiciled.

Competition

The property casualty insurance and reinsurance business is
competitive, with over 2,000 insurance companies transacting business in the
United States. The Company competes directly with a large number of these
companies. The Company's strategy in this highly fragmented industry is to seek
specialized areas or geographic regions where its insurance subsidiaries can
gain a competitive advantage by responding quickly to changing market
conditions. Each of the Company's subsidiaries establishes its own pricing
practices. Such practices are based upon a Company-wide philosophy to price
products with the general intent of making an underwriting profit. Competition
in the industry generally changes with profitability.

The regional property casualty subsidiaries compete with mutual and
other regional stock companies as well as national carriers. Direct writers of
property casualty insurance compete with the regional subsidiaries by writing
insurance through their salaried employees, generally at a lower cost than
through independent agents such as those used by the Company. Also, certain
personal lines have become more competitive due to Internet-based competition.

Signet Star's competition comes from domestic and foreign reinsurers,
many of which have greater financial resources than Signet Star and which place
their business either on a direct basis or through the broker market.

The E & S area is a highly specialized segment of the insurance
industry. Admiral and Nautilus compete with other E & S carriers, some of which
are larger and have greater resources than Admiral and Nautilus. Under certain
market conditions, standard carriers may compete for the types of business
written by Admiral and Nautilus. With the implementation of commercial lines
deregulation (see "Regulation") in several states and with many other states in
the process of considering or adopting such laws, competition for "E & S type
risks" might increase significantly. Such standard carriers would under such
deregulation be free to compete with more liberal rate and form requirements. In
addition, there are regional and


21
22
specialty carriers competing with Admiral and Nautilus when they underwrite
business in their regions or specialties.

Carolina and Great Divide's competition comes mainly from other
specialty transportation insurers, regional carriers and large national
multi-line companies. Each of Admiral Indemnity, Preferred and Key Risk
Insurance compete with local regional companies as well as national carriers.

Midwest Employers' competition comes from insurance and reinsurance
companies, some of which have greater financial resources than Midwest
Employers. Most of theses carriers write specific EWC coverage, do not offer
aggregate EWC coverage and tend to focus on risks larger than those targeted by
Midwest Employers. In addition, Midwest Employers competes with other specialty
EWC insurers.

The Insurance Services Operations face competition from several large
nationally known service organizations as well as local competitors. The
International Operations compete with native insurance operations both large and
small, which may be related to government entities, as well as with branch or
local subsidiaries of multi-national companies.

Employees

As of March 3, 2000, the Company employed 4,181 persons. Of this
number, the Company's subsidiaries employed 4,131 persons, of whom 2,690 were
executive and administrative personnel and 1,441 were clerical personnel. The
Company employed the remaining 50 persons in its parent company and investment
operations, of whom 36 were executive and administrative personnel and 14 were
clerical personnel.

Other information about the Company's business

The Company maintains an ongoing interest in acquiring additional
companies and developing new insurance entities, products and packages as
opportunities arise. In addition, the insurance subsidiaries develop new
coverages or lines of business to meet the needs of insureds.

Seasonal weather variations affect the severity and frequency of losses
sustained by the insurance and reinsurance subsidiaries. Although the effect on
the Company's business of such natural catastrophes as tornadoes, hurricanes,
hailstorms and earthquakes is mitigated by reinsurance, they nevertheless can
have a significant impact on the results of any one or more reporting periods.

The Company has no customer which accounts for 10 percent or more of
its consolidated revenues.

Compliance by the Company and its subsidiaries with federal, state and
local provisions which have been enacted or adopted regulating the discharge of
materials into the environment, or otherwise relating to protection of the
environment has not had a material effect upon the capital expenditures,
earnings or competitive position of the Company.

ITEM 2. PROPERTIES

The Company and its subsidiaries own or lease office buildings or office space
suitable to conduct their operations. Such owned property is as follows:



Location Company Size (sq. ft.)
-------- ------- --------------

Cherry Hill, New Jersey Admiral 42,000
Lincoln, Nebraska Union 43,000

Scottsdale, Arizona Nautilus 34,000
Urbandale, Iowa Continental Western 80,000
Westbrook, Maine Acadia 54,000


In addition, the Company and its subsidiaries lease office facilities
in various other cities under leases with varying terms and expiration dates.

23
ITEM 3. LEGAL PROCEEDINGS

Claims under insurance policies written by the Company's insurance
subsidiaries are investigated and settled either by claims adjusters employed by
them, by their independent agents or by independent adjusters. Generally, the
insurance subsidiary employs a staff of claims adjusters at its home office and
at some regional offices. Some independent agents may have the authority to
settle small claims. Independent claims adjusting firms are used to assist in
handling various claims in areas where insurance volume does not warrant the
maintenance of a staff adjuster. If a claim or loss cannot be settled and
results in litigation, the subsidiary generally retains outside counsel.

At present, neither the Company nor any of its subsidiaries is engaged
in any litigation known to the Company which is expected to have a material
adverse effect upon the Company's business. As is common with property casualty
insurance companies, the Company's subsidiaries are regularly engaged in the
defense of claims arising out of the conduct of the insurance business.
