PART I
------
ITEM 1. BUSINESS

(a) General Development of Business

The Progressive Corporation, an insurance holding company formed in 1965, has 88
subsidiaries and 1 mutual insurance company affiliate. The Progressive
Corporation's insurance subsidiaries and its affiliate (collectively, the
"Insurance Group") provide personal automobile insurance and other specialty
property-casualty insurance and related services throughout the United States
and in Canada. The Company's property-casualty insurance products protect its
customers against collision and physical damage to their motor vehicles and
liability to others for personal injury or property damage arising out of the
use of those vehicles.

Of the approximately 250 United States insurance company groups writing private
passenger auto insurance, the Company estimates that it ranks fifth in size for
1997. Except as otherwise noted, all industry data and Progressive's market
share or ranking in the industry were derived either directly from data reported
by A.M. Best Company Inc. ("A.M. Best") or were estimated using A.M. Best data
as the primary source. For 1997, the estimated industry premiums written, which
include personal auto insurance in the United States and Ontario, Canada, as
well as insurance for commercial vehicles, were $135.4 billion, and
Progressive's share of this market was approximately 3.3%.

(b) Financial Information About Industry Segments

Incorporated by reference from Note 9, SEGMENT INFORMATION, on
page 48 of the Company's Annual Report.

(c) Narrative Description of Business

INSURANCE SEGMENT
- -----------------

The Insurance Group offers a number of personal and commercial property-casualty
insurance products primarily related to motor vehicles. Net premiums written
were $4,665.1 million in 1997, compared to $3,441.7 million in 1996 and $2,912.8
million in 1995. The underwriting profit margin was 6.6% in 1997, compared to
8.5% in 1996 and 5.7% in 1995.

The Insurance Group's core business writes insurance for private passenger
automobiles, recreational vehicles and small fleets of commercial vehicles. This
business frequently has more than one program in a single state, with each
targeted to a specific market segment. The core business accounted for 96% of
the Company's 1997 total net premiums written.

A portion of the Insurance Group's core business consists of nonstandard
automobile insurance products for people cancelled or rejected by other
insurers. The size of the nonstandard automobile insurance market changes with
the insurance environment. Volume potential is influenced by the actions of
direct competitors, writers of standard and preferred automobile insurance and
state-mandated involuntary plans. The total direct premiums written in the
nonstandard automobile insurance market, including the involuntary market plans,
were about $25 billion in 1997, $24 billion in 1996 and $22 billion in 1995.
Approximately 340 nonstandard insurance companies, many of which are part of an
affiliated group, wrote an estimated $21 billion of nonstandard auto premiums in
1997, excluding the involuntary market plans. In 1996, the Insurance Group
ranked second in direct premiums written with a 14% share of this market and
near the top in underwriting performance. Although final data has not been
published, the Company estimates that its 1997 ranking and underwriting
performance will be consistent with 1996.

The core business also writes standard and preferred automobile risks in many
states. These products accounted for between 20% and 25% of the Company's total
core business premiums in 1997. The strategy is to build towards becoming a
low-cost provider of a full line of auto insurance and related services,
distributed through whichever channel the customer prefers. The Insurance
Group's goal is to compete successfully in the standard and preferred market,
which comprises 78% of the United States' personal automobile insurance market.

The Insurance Group's specialty personal lines products include motorcycle,
recreational vehicle, mobile home, boat and snowmobile insurance. The Insurance
Group's competitors are specialty companies and large multi-line insurance
carriers. Although industry figures are not available, based on the Company's
analysis of this market, the Company believes that it is a significant
participant in the specialty personal lines market.

Monoline commercial vehicle insurance covers commercial vehicle risks for
primary liability, physical damage and other supplementary insurance coverages.
Based on the Company's analysis of this market, the Company competes with
approximately 150 companies for this business on a nationwide basis. In the
target segment of monoline commercial auto writers, the Company estimates its
1997 ranking to be in the top 10.

In 1997, over 90% of the net premiums written by the core business were written
through a network of more than 30,000 independent insurance agents located
throughout the United States and in Canada. Subject to compliance with certain
Company-mandated procedures, these independent insurance agents have the
authority to bind the Company to specified insurance coverages within prescribed
underwriting guidelines. These guidelines prescribe the kinds and amounts of
coverage that may be written and the premium rates that may be charged for
specified categories of risk. The agents do not have authority on behalf of the
Company to settle or adjust claims, establish underwriting guidelines, develop
rates or enter into other transactions or commitments. The Company also markets
its products through intermediaries such as employers, other insurance companies
and national brokerage agencies, and direct to customers through employed sales
people and owned insurance agencies. The core business currently markets
personal automobile insurance directly to the public by direct mail, television
and radio advertising in 19 states and the District of Columbia.

To facilitate growth and the execution of its strategies, the Company expanded
to 54 the number of local business units to allow the Company to be closer to
the customer. The Company subdivides business units as growth produces enough
customers to warrant more local focus. Each business unit is headed by a
community manager and is headquartered in or near the market served. The
individual business units are responsible for reducing claim costs, improving
agent service and relationships, direct marketing and deciding price levels for
their territory. Processing (customer service calls, direct sales calls and
claims processing) is done at six regional sites located in Austin, Cleveland,
Colorado Springs, Toronto, Sacramento and Tampa.

In addition, the Company organized process teams made up of people from both
staff and line functions to support the business units. The process teams are
respectively responsible for product, independent agent marketing, consumer
marketing, ownership (customer service), technology, community manager support
and claims. The process teams concentrate on improving the processes fast enough
for the Company to meet its high standards for customer service, profit and
growth.

The Insurance Group's diversified businesses include the United Financial
Casualty Company (UFCC), Professional Liability Group (PLG) and Motor Carrier
business units, which are organized by customer group and headquartered in
Cleveland, Ohio, and the Midland Financial Group (MFG), which is headquartered
in Memphis, Tennessee. These businesses accounted for 4% of total volume in
1997. The choice of distribution channel is driven by each customer group's
buying preference and service needs. Distribution channels include financial
institutions, vehicle dealers and independent agents. Distribution arrangements
are individually negotiated between such intermediaries and the Company and are
tailored to the specific needs of the customer group and the nature of the
related financial or purchase transactions. The diversified businesses also
market their products directly to their customers through company- employed
sales forces.

UFCC provides physical damage insurance and related tracking services to protect
the commercial or retail lender's interest in collateral which is not otherwise
insured against these risks. The principal product is collateral protection for
automobile lenders, which is sold to financial institutions and/or their
customers. Commercial banks are UFCC's largest customer group for these
services. This business also serves savings and loans, finance companies and
credit unions. According to the Company's analysis of this market, numerous
companies offer these products and none of them has a dominant market share.

PLG's principal customers are community banks. Its principal products are
liability insurance for directors and officers and employee dishonesty
insurance. Progressive shares the risk and premium on these coverages with a
small mutual reinsurer controlled by its bank customers. The program is
sponsored by the American Bankers Association. This program represented less
than one-half percent of the Company's total 1997 net premiums written.

On March 7, 1997, the Company acquired MFG for about $50 million. MFG
underwrites and markets nonstandard private passenger automobile insurance
through approximately 3,700 independent agents across 11 states, primarily in
the southern and western United States. During 1997, Midland wrote $66.1 million
of net premiums written.

The Motor Carrier business unit primarily manages involuntary Commercial Auto
Insurance Procedures. See SERVICE OPERATIONS on page 7 for further discussion.

COMPETITIVE FACTORS
- -------------------

The automobile insurance and other property-casualty markets in which the
Company operates are highly competitive. Property-casualty insurers generally
compete on the basis of price, consumer recognition, coverages offered, claim
handling, financial stability, customer service and geographic coverage.
Vigorous competition is provided by large, well-capitalized national companies,
some of which have broad distribution networks of employed or captive agents,
and by smaller regional insurers. While the Company relies heavily on technology
and extensive data gathering and analysis to segment and price markets according
to risk potential, some competitors merely price their coverage at rates set
lower than the Company's published rates. By avoiding extensive data gathering
and analysis, these competitors incur lower underwriting costs. The Company has
remained competitive by closely managing expenses and achieving operating
efficiencies, and by refining its risk measurement and price segmentation
skills. In addition, the Company offers prices for a wide spectrum of risks and
seeks to offer a wider array of payment plans, limits of liability and
deductibles than its competitors. Superior customer service and claim adjustment
are also important factors in the Company's competitive strategy.

LICENSES
- --------

The Insurance Group operates under licenses issued by various state or
provincial insurance authorities. Such licenses may be of perpetual duration or
renewable periodically, provided the holder continues to meet applicable
regulatory requirements. The licenses govern the kind of insurance coverages
which may be written in the issuing state. Such licenses are normally issued
only after the filing of an appropriate application and the satisfaction of
prescribed criteria. All licenses which are material to the Company's business
are in good standing.

INSURANCE REGULATION
- --------------------

The insurance subsidiaries are generally subject to regulation and supervision
by insurance departments of the jurisdictions in which they are domiciled or
licensed to transact business. At least one of the subsidiaries is licensed and
subject to regulation in each of the 50 states and certain U.S. possessions, in
one Canadian province and by Canadian federal authorities. The nature and extent
of such regulation and supervision varies from jurisdiction to jurisdiction.
Generally, an insurance company is subject to a higher degree of regulation and
supervision in its state of domicile. The Company's principal insurance
subsidiaries are domiciled in the states of California, Colorado, Florida,
Louisiana, Michigan, Mississippi, Missouri, New York, Ohio, Pennsylvania,
Tennessee, Texas, Washington and Wisconsin. State insurance departments have
broad administrative power relating to licensing insurers and agents, regulating
premium rates and policy forms, establishing reserve requirements, prescribing
accounting methods and the form and content of statutory financial reports, and
regulating the type and amount of investments permitted. Rate regulation varies
from "file and use" to prior approval to mandated rates. Most jurisdictions
prohibit rates that are "excessive, inadequate or unfairly discriminatory."

Insurance departments are charged with the responsibility of ensuring that
insurance companies maintain adequate capital and surplus and comply with a
variety of operational standards. Insurance companies are generally required to
file detailed annual and other reports with the insurance department of each
jurisdiction in which they conduct business. Insurance departments are
authorized to make periodic and other examinations of regulated insurers'
financial condition, adherence to statutory accounting principles and compliance
with state insurance laws and regulations.

Insurance holding company laws enacted in many jurisdictions grant to insurance
authorities the power to regulate acquisitions of insurers and certain other
transactions involving insurers and to require periodic disclosure of certain
information. These laws impose prior approval requirements for certain
transactions between regulated insurers and their affiliates and generally
regulate dividend and other distributions, including loans and cash advances,
between regulated insurers and their affiliates. See the "Dividends" discussion
in Item 5(c) for further information on such dividend limitations.

Under state insolvency and guaranty laws, regulated insurers can be assessed or
required to contribute to state guaranty funds to cover policyholder losses
resulting from insurer insolvencies. Insurers are also required by many states,
as a condition of doing business in the state, to provide coverage to certain
risks. These so-called "assigned risk" plans generally specify the types of
insurance and the level of coverage which must be offered to such involuntary
risks, as well as the allowable premium. Many states also have involuntary
market plans which hire a limited number of servicing carriers to provide
insurance to involuntary risks. These plans, through assessments, pass
underwriting and administrative expenses on to insurers that write voluntary
coverages.

Insurance companies are generally required by insurance regulators to maintain
sufficient surplus to support their writings. Although the ratio of writings to
surplus that the regulators will allow is a function of a number of factors,
including the type of business being written, the adequacy of the insurer's
reserves, the quality of the insurer's assets, and the identity of the
regulator, as a general rule, the regulators prefer that annual net written
premium be not more than three times the insurer's total policyholders' surplus.
Thus, the amount of an insurer's surplus may, in certain cases, limit its
ability to grow its business.

Many states have laws and regulations that limit an insurer's ability to exit a
market. For example, certain states limit an automobile insurer's ability to
cancel and non-renew policies. Furthermore, certain states prohibit an insurer
from withdrawing one or more lines of business from the state, except pursuant
to a plan that is approved by the state insurance department. The state
insurance department may disapprove a plan that may lead to market disruption.
Laws and regulations that limit cancellation and non-renewal and that subject
program withdrawals to prior approval requirements may restrict an insurer's
ability to exit unprofitable markets.

Regulation of insurance constantly changes as real or perceived issues and
developments arise. Some changes may be due to technical factors, such as
changes in investment laws made to recognize new investment vehicles; other
changes result from such general pressures as consumer resistance to price
increases and concerns relating to insurer solvency. In recent years,
legislation and voter initiatives have been introduced which deal with insurance
rate development, rate

determination and the ability of insurers to cancel or renew insurance policies,
reflecting concerns about availability, prices and alleged discriminatory
pricing.

In some states, the automobile insurance industry has been under pressure in
recent years from regulators, legislators or special interest groups to reduce,
freeze or set rates to or at levels that are not necessarily related to
underlying costs, including initiatives to roll back automobile and other
personal lines rates. This kind of activity has adversely affected, and may in
the future adversely affect, the profitability and growth of the subsidiaries'
automobile insurance business in those jurisdictions, and may limit the
subsidiaries' ability to increase rates to compensate for increases in costs.
Adverse legislative and regulatory activity limiting the subsidiaries' ability
to adequately price automobile insurance may occur in the future. The impact of
these regulatory changes on the subsidiaries' businesses cannot be predicted.

The state insurance regulatory framework has come under increased federal
scrutiny, and certain state legislatures have considered or enacted laws that
alter and, in many cases, expand state authority to regulate insurance companies
and insurance holding company systems. Further, the National Association of
Insurance Commissioners (NAIC) and state insurance regulators are re-examining
existing laws and regulations, specifically focusing on insurance company
investments, issues relating to the solvency of insurance companies and further
limitations on the ability of regulated insurers to pay dividends. The NAIC also
developed a risk-based capital (RBC) program to enable regulators to take
appropriate and timely regulatory actions relating to insurers that show signs
of weak or deteriorating financial conditions. RBC is a series of dynamic
surplus-related formulas which contain a variety of factors that are applied to
financial balances based on a degree of certain risks, such as asset, credit and
underwriting risks. In addition, from time to time, the United States Congress
and certain federal agencies investigate the current condition of the insurance
industry to determine whether federal regulation is necessary.

STATUTORY ACCOUNTING PRINCIPLES
- -------------------------------

The Insurance Group's results are reported in accordance with generally accepted
accounting principles (GAAP), which differ from amounts reported under statutory
accounting principles (SAP) prescribed by insurance regulatory authorities.
Specifically, under GAAP:

1. Commissions, premium taxes and other costs incurred in connection with
writing new and renewal business are capitalized and amortized on a pro
rata basis over the period in which the related premiums are earned,
rather than expensed as incurred, as required by SAP.

2. Certain assets are included in the consolidated balance sheets, which
for SAP are charged directly against statutory surplus. These assets
consist primarily of premium receivables over 90 days, furniture and
equipment and prepaid expenses.

3. Amounts related to ceded reinsurance are shown gross as prepaid
reinsurance premiums and reinsurance recoverables, rather than netted
against unearned premium reserves and loss and loss adjustment expense
reserves, respectively, as required by SAP.

4. Fixed maturities securities, which are classified as
available-for-sale, are reported at market values, rather than at
amortized cost, or the lower of amortized cost or market depending on
the specific type of security as required by SAP. Equity securities are
reported at quoted market values which may differ from the NAIC market
values as required by SAP.

The differing treatment of income and expense items results in a corresponding
difference in federal income tax expense.

SERVICE OPERATIONS
- -------------------

The service operations of the diversified business units consist primarily of
processing business for involuntary plans and providing claim services to fleet
owners and other insurance companies. Service revenues were $45.3 million in
1997, compared to $46.2 million in 1996 and $38.9 million in 1995. Pretax
operating profits were $1.4 million in 1997, compared to $4.3 million and $8.7
million in 1996 and 1995, respectively.

The Motor Carrier business unit currently processes business for the Commercial
Auto Insurance Procedures (CAIP) in 27 states and the New York Public Automobile
Pool (NYPAP), which are both part of the involuntary residual market. As a CAIP
servicing carrier, the business unit processes over 40% of the premiums in the
CAIP market without assuming the indemnity risk. It competes with approximately
7 other providers nationwide. During 1997, the unit increased their share of the
NYPAP to 40% of the new business.

INVESTMENTS
- -----------

The Company employs a conservative approach to investment and capital management
intended to ensure that there is sufficient capital to support all the insurance
premium that can be profitably written. The Company's portfolio is invested
primarily in short-term and intermediate-term, investment-grade fixed-income
securities. The Company's investment portfolio, at market value, was $5,270.4
million at December 31, 1997, compared to $4,450.6 million at December 31, 1996.
Investment income is affected by shifts in the types of investments in the
portfolio, changes in interest rates and other factors. Investment income,
including net realized gains on security sales, before expenses and taxes, was
$373.4 million in 1997, compared to $232.9 million in 1996 and $245.8 million in
1995. See MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS, beginning on page 14 herein for additional discussion.

EMPLOYEES
- ---------

The number of employees, excluding temporary employees, at December 31, 1997,
was 14,126.

LIABILITY FOR PROPERTY-CASUALTY LOSSES AND LOSS ADJUSTMENT EXPENSES
- -------------------------------------------------------------------

The consolidated financial statements include the estimated liability for unpaid
losses and loss adjustment expenses (LAE) of the Company's insurance
subsidiaries. Total loss reserves are established at a level that is intended to
represent the midpoint of the reasonable range of loss reserve estimates. The
liabilities for losses and LAE are determined using actuarial and statistical
procedures and represent undiscounted estimates of the ultimate net cost of all
unpaid losses and LAE incurred through December 31 of each year. These estimates
are subject to the effect of future trends on claim settlement. These estimates
are continually reviewed and adjusted as experience develops and new information
becomes known. Such adjustments, if any, are reflected in the current results of
operations.


The accompanying tables present an analysis of property-casualty losses and LAE.
The following table provides a reconciliation of beginning and ending estimated
liability balances for 1997, 1996 and 1995 on a GAAP basis.

==================================================================



The reconciliation above shows a $103.3 million redundancy, which emerged during
1997, in the 1997 liability and a $105.8 million redundancy in the 1996
liability, based on information known as of December 31, 1997 and December 31,
1996, respectively.

The anticipated effect of inflation is explicitly considered when estimating
liabilities for losses and LAE. While anticipated increases due to inflation are
considered in estimating the ultimate claim costs, the increase in average
severities of claims is caused by a number of factors that vary with the
individual type of policy written. Future average severities are projected based
on historical trends adjusted for anticipated changes in underwriting standards,
inflation, policy provisions and general economic trends. These anticipated
trends are monitored based on actual development and are modified if necessary.

The Company has not entered into any loss reserve transfers or similar
transactions having a material effect on earnings or reserves.

losses and LAE recorded at the balance sheet date for each of the indicated
years for the property-casualty insurance subsidiaries only. Similar reserves
for the life insurance subsidiary, which are immaterial, are excluded. This
liability represents the estimated amount of losses and LAE for claims arising
in all prior years that are unpaid at the balance sheet date, including losses
that had been incurred but not reported.

10


The upper section of the table shows the cumulative amount paid with respect to
the previously recorded liability as of the end of each succeeding year. The
lower portion of the table shows the re-estimated amount of the previously
recorded liability based on experience as of the end of each succeeding year.
The estimate is increased or decreased as more information about the claims
becomes known for individual years. For example, as of December 31, 1997 the
companies had paid $551.7 million of the currently estimated $575.0 million of
losses and LAE that had been incurred through the end of 1988; thus an estimated
$23.3 million of losses incurred through 1988 remain unpaid as of the current
financial statement date.

The "Cumulative Redundancy" represents the aggregate change in the estimates
over all prior years. For example, the 1987 liability has developed redundant by
$62.5 million over ten years. That amount has been reflected in income over the
ten years and did not have a significant effect on the income of any one year.
The effects on income during the past three years due to changes in estimates of
the liabilities for losses and LAE is shown in the reconciliation table on page
8 as the "prior years" contribution to incurred losses and LAE.

In evaluating this information, note that each cumulative redundancy amount
includes the effects of all changes in amounts during the current year for prior
periods. For example, the amount of the redundancy related to losses settled in
1990, but incurred in 1987, will be included in the cumulative deficiency or
redundancy amount for years 1987, 1988 and 1989. Conditions and trends that have
affected development of the liability in the past may not necessarily occur in
the future. Accordingly, it generally is not appropriate to extrapolate future
redundancies or deficiencies based on this table.

The Analysis of Loss and Loss Adjustment Expenses Development table on page 9 is
constructed from Schedule P, Part-1, from the 1991 through 1997 Consolidated
Annual Statements, as filed with the state insurance departments, and Schedules
O and P filed for years prior to 1991. This development table differs from the
development displayed in Schedule P, Part-2 due to the fact Schedule P, Part-2
excludes unallocated loss adjustment expenses and reflects the change in the
method of accounting for salvage and subrogation for 1994 and prior.

(d) Financial Information about Foreign and Domestic Operations

The Company operates throughout the United States and in Canada. The amount of
Canadian revenues and assets are approximately 2% of the Company's consolidated
revenues and assets. The amount of operating income (loss) generated by its
Canadian operations is immaterial with respect to the Company's consolidated
operating income.

ITEM 2. PROPERTIES

The Company's 517,800 square foot corporate office complex is located on a
42-acre parcel in Mayfield Village, Ohio, owned by a subsidiary. The Company's
central data processing facility occupies a building containing approximately
107,000 square feet of office space, on this same parcel.

The Company also owns six other buildings in suburbs adjoining the corporate
office complex, two buildings in Tampa, Florida, a building in Tempe, Arizona
and a building in Tigard, Oregon. In total, these buildings contained
approximately 782,900 square feet of office, warehouse and training facility
space and are owned by subsidiaries of the Company. These locations are occupied
by the Company's business units or other operations.

In December 1997, the Company purchased approximately 72 acres in Tampa, Florida
to construct a three-building regional call center. It is estimated that, when
completed, this facility will consist of approximately 307,000 square feet of
space. The cost of the project is currently estimated at $42.0 million and $8.3
million has been paid as of December 31, 1997. The project is scheduled to be
completed by the end of 1998. In addition, in November 1997, the Company
purchased 91 acres in Mayfield Village, Ohio to construct an office complex,
near the site of its current corporate headquarters. This office complex is part
of a five-year cooperative effort with Mayfield Village to develop over 300
acres -- Progressive would serve as the anchor corporate user with additional
business users and recreational facilities on the site. The Company plans to
construct three buildings containing a total of approximately 485,000 square
feet in 1998 and could build up to three additional buildings, containing about
500,000 additional square feet in total, in the future. The first phase of this
project is estimated to cost $63.5 million. As of December 31, 1997, $5.3
million has been paid. The construction projects will be funded through
operating cash flows or the issuance of new debt securities.

The Company leases approximately 283,000 square feet of office and warehouse
space at various locations throughout the United States for its other business
units and staff functions. In addition, the Company leases approximately 400
claim offices, or 1,665,000 square feet, at various locations throughout the
United States. Two offices are leased in Canada. These leases are generally
short-term to medium-term leases of standard commercial office space.

As the Company continues to grow, it expects the need for additional space and
is actively engaged in seeking out additional locations to meet its current and
anticipated needs.

The closing price of the Company's Common Shares on February 27, 1998 was
$115 7/8.

(b) Holders

There were 4,074 shareholders of record on February 27, 1998.

(c) Dividends

Statutory policyholders' surplus was $1,725.3 million and $1,292.4 million at
December 31, 1997 and 1996, respectively. Generally, under state insurance laws,
the net admitted assets of insurance subsidiaries available for transfer to a
corporate parent are limited to those net admitted assets, as determined in
accordance with SAP, which exceed minimum statutory capital requirements. At
December 31, 1997, $234.3 million of consolidated statutory policyholders'
surplus represents net admitted assets of the insurance subsidiaries that are
required to meet minimum statutory surplus requirements in the subsidiaries'
states of domicile. Furthermore, state insurance laws limit the amount that can
be paid as a dividend or other distribution in any given year without prior
regulatory approval and adequate policyholders' surplus must be maintained to
support premiums written. Based on the dividend laws currently in effect, the
insurance subsidiaries may pay aggregate dividends of $191.9 million in 1998 out
of statutory policyholders' surplus, without prior approval by regulatory
authorities.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

FINANCIAL CONDITION The Progressive Corporation is a holding company and does
not have any revenue producing operations of its own. It receives cash through
borrowings, equity sales, subsidiary dividends and other transactions, and may
use the proceeds to contribute to the capital of its insurance subsidiaries in
order to support premium growth, to repurchase its Common Shares and other
outstanding securities, to retire its outstanding indebtedness, and for other
business purposes. During 1997, the Company repurchased 30,193 of its Common
Shares at a total cost of $2.9 million in connection with obligations under
various employee benefit plans.

During the three-year period ended December 31, 1997, the Company repurchased
1.0 million of its Common Shares at a total cost of $44.8 million (average
$43.37 per share), .3 million of its 9 3/8% Serial Preferred Shares, Series A,
at a total cost of $8.3 million (average $25.62 per share) and redeemed its
remaining Preferred Shares at a total cost of $82.1 million ($25.00 per share).
The Company also sold $100.0 million of Notes. During the same period, The
Progressive Corporation received $50.8 million from its subsidiaries, net of
capital contributions made to these subsidiaries. The regulatory restrictions on
subsidiary dividends are described in Item 5(c) on page 12 herein.

The Company has substantial capital resources and is unaware of any trends,
events or circumstances that are reasonably likely to affect its capital
resources in a material way. The Company also has available a $10.0 million
revolving credit agreement. With its 27% debt to capital ratio, management
believes the Company has sufficient borrowing capacity and other capital
resources to support current and anticipated growth.

The Company's insurance operations create liquidity by collecting and investing
premiums from new and renewal business in advance of paying claims. For the
three years ended December 31, 1997, operations generated a positive cash flow
of $1,917.5 million, and cash flow is expected to be positive in both the
short-term and reasonably foreseeable future. The Company's substantial
investment portfolio is highly liquid, consisting almost entirely of readily
marketable securities.

In March 1997, the Company acquired Midland Financial Group, Inc. by purchasing
all of Midland's outstanding stock for about $50 million in cash. Midland
underwrites and markets nonstandard private passenger automobile insurance
through approximately 3,700 independent agents across 11 states, primarily in
the southern and western United States. During 1997, Midland wrote $66.1 million
of net premiums written.

Total capital expenditures for the three years ended December 31, 1997,
aggregated $196.0 million. During 1997, the Company made substantial investments
in property and equipment to support its infrastructure. In December 1997, the
Company purchased approximately 72 acres in Tampa, Florida to construct a
three-building regional call center. It is estimated that, when completed, this
facility will consist of approximately 307,000 square feet of space. The cost of
the project is currently estimated at $42.0 million and $8.3 million has been
paid as of December 31, 1997. The project is scheduled to be completed by the
end of 1998. In addition, in November 1997, the Company purchased 91 acres in
Mayfield Village, Ohio to construct an office complex, near the site of its
current corporate headquarters. This office complex is part of a five-year
cooperative effort with Mayfield Village to develop over 300 acres --
Progressive would serve as the anchor corporate user with additional business
users and recreational facilities on the site. The Company plans to construct
three buildings containing a total of approximately 485,000 square feet, in
1998, and could build up to three additional buildings, containing about 500,000
additional square feet in total, in the future. The first phase of this project
is estimated to cost $63.5 million. As of December 31, 1997, $5.3 million has
been paid. The construction projects will be funded through operating cash flows
or the issuance of new debt securities.

In July 1995, the Company began converting its computer systems to be year 2000
compliant (e.g. to recognize the difference between '99 and '00 as one year
instead of negative 99 years). The Company has evaluated internal production
systems, hardware and software products, facilities implications, and
interactions with business partners in relation to year 2000 issues. As of
December 31, 1997, the Company has completed approximately 70% of its efforts to
bring the production systems in compliance, with substantially all production
systems expected to be compliant by the end of 1998. The total cost to modify
these existing production systems, which include both internal and external
costs of programming, coding and testing, is estimated to be $6.4 million, of
which $3.1 million has been expensed as of December 31,

14
15

1997. The Company is also in the process of replacing some of its systems during
1998 with new systems which, in addition to being year 2000 compliant, will add
increased functionality to the Company. The total cost of these systems, which
include both internal and external costs, is estimated to be $4.8 million, and
the projects are expected to be substantially complete by the end of 1998. As of
December 31, 1997, $2.4 million has been expensed for these systems. All costs
are being funded through operating cash flow. The Company continually evaluates
computer hardware and software upgrades and, therefore, many of the costs to
replace existing items with year 2000 compliant upgrades are not likely to be
incremental costs to the Company. It is estimated that the majority of these
upgrades will be completed in 1998. During 1998, the Company will continue to
contact its business partners (e.g. agents, banks, credit bureaus, motor vehicle
departments, rating agencies, etc.) to determine their status of compliance and
to assess the impact of noncompliance to the Company. The Company believes that
it is taking the necessary measures to mitigate issues that may arise relating
to the year 2000. During 1998, the Company will develop contingency plans
relating to year 2000 compliance issues, either internal or external, that
cannot be guaranteed to be timely completed. To the extent any additional issues
arise, the Company will evaluate the impact on its financial condition, cash
flows and results of operations and, if material, make the necessary
disclosures.


INVESTMENTS The Company invests in fixed-maturity, equity and short-term
securities. The Company's investment strategy recognizes its need to maintain
capital adequate to support its insurance operations. The Company evaluates the
risk/reward trade-offs of investment opportunities, measuring their effects on
stability, diversity, overall quality and liquidity of the investment portfolio.

The majority of the portfolio is invested in high-grade, fixed-maturity
securities, of which short- and intermediate-term securities represented
$4,024.9 million, or 76.4%, at the end of 1997, compared to $3,275.6 million, or
73.6%, at the end of 1996. Long-term investment-grade securities, including
greater than 10-year expected principal paydowns, were $143.4 million, or 2.7%,
at the end of 1997, compared to $187.5 million, or 4.2%, at the end of 1996.
Non-investment- grade fixed-maturity securities were $132.5 million, or 2.5%, at
the end of 1997, compared $105.8 million, or 2.4%, at the end of 1996, and offer
the Company higher returns and added diversification without a significant
adverse effect on the stability and quality of the investment portfolio as a
whole. Non-investment-grade securities may involve greater risks often related
to creditworthiness, solvency and relative liquidity of the secondary trading
market. The duration of the fixed-income portfolio was 3.3 years at December 31,
1997, compared to 3.2 years at December 31, 1996.

A portion of the investment portfolio was invested in marketable equity
securities. Common stocks represented $620.8 million, or 11.8% of the portfolio,
at the end of 1997, compared to $540.1 million, or 12.1%, a year earlier.
Foreign equities, which may include stock index futures and foreign currency
forwards, comprised $106.0 million of the common stock portfolio at the end of
1997, and $149.5 million at the end of 1996. As of December 31, 1997, the
Company's Japanese equity holdings represented 1.5% of the common stock
portfolio. The remainder of the equity portfolio of $348.8 million, or 6.6%, at
the end of 1997, compared to $341.6 million, or 7.7%, at the end of 1996, was
comprised of over 80% of fixed-rate preferred stocks with mechanisms that are
expected to provide an opportunity to liquidate at par.

As of December 31, 1997, the Company's portfolio had $188.4 million in
unrealized gains, compared to $114.1 million a year earlier. This increase in
value was the result of increased stock prices as the S&P 500 index rose from
740.7 to 970.4 and decreased interest rate levels as evidenced by the .3%
decrease in the 3-year treasury note.

The weighted average fully taxable equivalent book yield of the portfolio was
6.6%, 6.7% and 6.9% for the years ended December 31, 1997, 1996 and 1995,
respectively.

-------------------------- --------------------- ---------------------

AAA 67.5% 62.8%
AA 13.0 16.2

===================== =====================



As of December 31, 1997, the Company held $1,520.0 million of asset-backed
securities, which represented 28.8% of the total investment portfolio. The
portfolio included collateralized mortgage obligations (CMO) and commercial
mortgage-backed obligations (CMB) totaling $283.2 million and $776.7 million,
respectively. The remainder of the asset-backed portfolio was invested primarily
in auto loan and other asset-backed securities. As of December 31, 1997, the CMO
portfolio included busted planned amortization class bonds and sequential bonds
representing 94.1% of the CMO portfolio ($266.4 million) with an average life of
3.0 years, and planned amortization class bonds representing 5.9% of the CMO
portfolio ($16.8 million) with an average life of .5 years.

At December 31, 1997, the CMO portfolio had a weighted average Moody's or
Standard & Poor's rating of AAA and the CMB portfolio had an average life of 7.4
years and a weighted average Moody's or Standard & Poor's rating of AA. At
December 31, 1997, the CMO and CMB portfolios had unrealized gains of $1.6
million and $14.0 million, respectively. The single largest unrealized loss in
any individual CMO security was $.2 million and in any CMB security was $1.1
million, at December 31, 1997. The CMB portfolio includes $149.6 million of CMB
interest-only certificates, which had an average life of 6.9 years and a
weighted average Moody's or Standard & Poor's rating of AAA at December 31,
1997. Both the CMO and CMB portfolios are highly liquid with readily available
quotes and contain no residual interests. During 1997, the Company sold $178.4
million (proceeds of $200.8 million) of non-investment-grade CMB securities to a
third-party purchaser. The purchaser subsequently transferred the securities to
a trust as collateral in a resecuritized debt offering. The transaction was
accounted for as a sale under SFAS 125, "Accounting for Transfers and Servicing
of Financial Assets and Extinguishments of Liabilities," resulting in a net gain
of $22.4 million. A bankruptcy remote subsidiary of the Company acquired $22.8
million (market value of $25.9 million) of the resecuritized debt. This portion
of the transaction was not accounted for as a sale in accordance with SFAS 125.

Investments in the Company's portfolio have varying degrees of risk. The primary
market risk exposure to the fixed-income portfolio is interest rate risk, which
is limited by managing duration to a defined range of 1.8 to 5 years. The
distribution of maturities and convexity are monitored on a regular basis.
Common stocks and similar investments, which generally have greater risk and
volatility of market value, are limited to a target of 15%, with a range of 0 to
25%. Market values, along with industry and sector concentrations of common
stocks and similar investments, are monitored daily. Exposure to foreign
currency exchange risk is limited by Company restrictions and is monitored
regularly. Exposures are evaluated individually and as a whole, considering the
effects of cross correlation. For the quantitative market risk disclosures, see
page 54 of the Company's 1997 Annual Report. The Company regularly examines its
portfolio for evidence of impairment. In such cases, changes in market value are
evaluated to determine the extent to which such changes are attributable to: (i)
interest rates, (ii) market-related factors other than interest rates and (iii)
financial conditions, business prospects and other fundamental factors specific
to the issuer. Declines attributable to issuer fundamentals are reviewed in
further detail. Available evidence is considered to estimate the realizable
value of the investment. When a security in the Company's investment portfolio
has a decline in market value which is other than temporary, the Company is
required by generally accepted accounting principles (GAAP) to reduce the
carrying value of such security to its net realizable value.

Derivative instruments are primarily used to manage the risks and enhance the
returns of the available-for-sale portfolio. This is accomplished by modifying
the basis, duration, interest rate or foreign currency characteristics of the
portfolio or

16
17

hedged securities. Derivative instruments may also be used for trading purposes.
During 1997, net activity in the trading portfolio was not material to the
Company's financial position, cash flows and results of operations. Net cash
requirements of derivative instruments are limited to changes in market values
which may vary based upon changes in interest rates and other factors. Exposure
to credit risk is limited to the carrying value; collateral is not required to
support the credit risk. The Company has stringent restrictions on the amount of
open positions in the trading portfolios, limiting exposure to levels management
deems acceptable. At December 31, 1997, trading positions had a net market value
of $1.1 million; at December 31, 1996, there were no trading positions.


RESULTS OF OPERATIONS Operating income, which excludes net realized gains and
losses from security sales and one-time items, was $336.0 million, or $4.46 per
share, in 1997, $309.1 million, or $4.12 per share, in 1996 and $220.1 million,
or $2.85 per share, in 1995. The GAAP combined ratio was 93.4 in 1997, 91.5 in
1996 and 94.3 in 1995.

Direct premiums written increased 33% to $4,825.2 million in 1997, compared to
$3,638.4 million in 1996 and $3,068.9 million in 1995. Net premiums written
increased 36% to $4,665.1 million in 1997, compared to $3,441.7 million in 1996
and $2,912.8 million in 1995. The difference between direct and net premiums
written is largely attributable to premiums written under state-mandated
involuntary Commercial Auto Insurance Procedures (CAIP), for which the Company
retains no indemnity risk, of $78.4 million in 1997, $99.5 million in 1996 and
$105.4 million in 1995. The Company provided policy and claim processing
services to 27 state CAIPs in 1997 and 1996, compared to 28 in 1995. Premiums
earned, which are a function of the amount of premiums written in the current
and prior periods, increased 31% in 1997, compared to 17% in 1996 and 24% in
1995.

In the Company's core business units, which write insurance for private
passenger automobiles, recreational vehicles and small fleets of commercial
vehicles, net premiums written grew 33%, 19% and 21% in 1997, 1996 and 1995,
respectively, reflecting an increase in unit sales driven by the Company's
competitive rates. The Company decreased rates an average of .9% in 1997,
compared to rate increases of 2.5% and 6.5% in 1996 and 1995, respectively. The
Company continues to write, through multiple distribution methods, standard and
preferred risks, which represented between 20% and 25% of total 1997 core
business volume. In 1997, the Company used rating criteria based partially upon
consumer financial responsibility. This approach has been approved by numerous
regulators and is in use in the 31 states that represent 80% of the core
business units' volume; the Company expects to complete rollout of this approach
into the remaining states where it can be offered in 1998. The Company believes
that its use of financial responsibility in auto insurance rating produces a
more accurate distribution of losses among consumers and, therefore, produces
more accurate pricing resulting in lower rates for most consumers. In addition,
in order to encourage writing more standard and preferred risks and to improve
customer retention, the Company in 1996 adjusted its contingent cash incentive
compensation program for employees to reflect the increase in value created by
adding new customers. The Company believes that growing the numbers of
policyholders, particularly standard and preferred risks with their higher
retention rates, builds intrinsic value because renewals are more profitable
than first year business. The drive to add customers faster resulted in more
spending to promote the Progressive brand and to hire and develop more claim
adjusters and customer service representatives, and the Company expects this to
continue at least in the near term. These costs, along with lower margins on
first year business, are likely to bring profit margins more in line with the
Company's objective of achieving a 4% underwriting profit margin over the entire
retention period of an insured. In 1997, the core business units generated an
underwriting profit margin of 7%, compared to 8% in 1996 and 5% in 1995.

Claim costs, the Company's most significant expense, represent actual payments
made and changes in estimated future payments to be made to or on behalf of its
policyholders, including expenses required to settle claims and losses. These
costs include a loss estimate for future assignments and assessments, based on
current business, under state-mandated involuntary automobile programs. Claims
costs are influenced by inflation and loss severity and frequency, the impact of
which is mitigated by adequate pricing. Increases in the rate of inflation
increase loss payments, which are made after premiums are established.
Accordingly, anticipated rates of inflation are taken into account when the
Company establishes premium rates and loss reserves. Claim costs, expressed as a
percentage of premiums earned, were 71% in 1997, compared to 70% in 1996 and 71%
in 1995.

The Company writes directors and officers and other professional liability
coverage for community banks and credit unions and, therefore, could potentially
be exposed to liability for errors made by these institutions relating to the
year 2000 conversion. To minimize its risk, in October 1997, the Company began
including year

17
18

2000 exclusions in all new and renewal policies for commercial banks
(representing approximately 70% of all policies written since that date) which
have multi-year terms that extend beyond December 31, 1999. The Company is not
currently aware of any other company in the industry that is including such
exclusion provisions or increasing their premiums to cover potential exposure on
year 2000 compliance issues. As a regulated industry, financial institutions are
under pressure from government regulatory agencies and other interested parties
to ensure they achieve readiness for the year 2000. The Company is monitoring
its customers' compliance efforts and believes that substantially all such
customers are pursuing plans to achieve year 2000 compliance. It is currently
unknown whether the financial institutions will be able to completely avoid
errors relating to year 2000 compliance and the Company is unable to predict to
what extent such financial institutions will incur losses as a result of
noncompliance and whether their directors and officers will be subject to
individual liability for such noncompliance. At December 31, 1997, approximately
200 professional liability policies, or about 17% of all policies, do not
contain year 2000 exclusion provisions and extend into the year 2000. In the
event of a claim, applicable factual and coverage issues would have to be
resolved. Based on information currently available and management's best
estimate, the Company does not believe that it will incur any costs that will
have a material impact on the Company's financial condition, cash flows or
results of operations.

Because the Company is primarily an insurer of motor vehicles, it has limited
exposure for environmental, product and general liability claims. The Company
has established reserves for these exposures, in amounts which it believes to be
adequate based on information currently known by it. Management does not believe
that these claims will have a material impact on the Company's liquidity,
financial condition, cash flows or results of operations.

Policy acquisition and other underwriting expenses as a percentage of premiums
earned were 23% in 1997, compared to 22% in 1996 and 23% in 1995. In 1997, the
Company incurred additional expenses to support its infrastructure and to hire
and train people in anticipation of growth. The Company also introduced its
advertising campaign to 13 states during 1997, bringing the total number of
states where the Company advertises to 19 (40 markets).

Recurring investment income (interest and dividends) increased 22% to $274.9
million in 1997, compared to $225.8 million in 1996 and $199.1 million in 1995,
primarily due to an increase in the size of the investment portfolio. Net
realized gains on security sales were $98.5 million in 1997, $7.1 million in
1996 and $46.7 million in 1995. Investment expenses were $9.9 million in 1997,
compared to $6.1 million in 1996 and $8.1 million in 1995; in 1997, the Company
purchased a new portfolio management system and incurred expenses related to the
sale of the commercial mortgage-backed securities.

on Form 10-K, supplementing the Notes to the Consolidated Financial Statements
which are incorporated by reference therein:

Note 1. Reporting and Accounting Policies
- ------- ---------------------------------

NEW ACCOUNTING STANDARDS - In March 1998, the American Institute of Certified
Public Accountants issued Statement of Position (SOP) 98-1, "Accounting for the
Costs of Computer Software Developed or Obtained for Internal Use," which is
effective for fiscal years beginning after December 15, 1998, with early
adoption permitted. SOP 98-1 provides guidance on accounting for the costs of
computer software developed or obtained for internal use, identifying when such
costs should be capitalized rather than expensed as incurred. The Company
currently expenses all computer software costs. The Company is planning to early
adopt SOP 98-1 in the first quarter 1998 and is currently quantifying the impact
to its financial condition and results of operations.

Debt includes amounts the Registrant has borrowed and contributed to the capital
of its insurance subsidiaries or borrowed for other long-term purposes.

All debt is noncallable with interest payable semiannually.

In May 1990, the Registrant entered into a revolving credit arrangement with
National City Bank, which is reviewed by the bank annually. Under this
agreement, the Registrant had the right to borrow up to $50.0 million. In
February 1994, the Registrant reduced this revolving credit arrangement to $20.0
million and in May 1997, further reduced it to $10.0 million. By selecting from
available credit options, the Registrant may elect to pay interest at rates
related to the London interbank offered rate, the bank's base rate or at a money
market rate. A commitment fee is payable on any unused portion of the committed
amount at the rate of .125% per annum. At December 31, 1997 and 1996, the
Registrant had no borrowings under this arrangement.
