                                     PART I

ITEM 1.  BUSINESS.

      The Registrant is a holding company whose operating  subsidiaries carry on
business in three distinct operating segments: (i) insurance brokerage and other
services,  (ii) consulting,  and (iii) insurance  underwriting.  Incorporated in
1979, it is the parent corporation of long-established  and more recently formed
companies.

      The Registrant acquired,  among other companies and businesses,  Actuarial
Sciences  Associates,  Inc. (ASA), an employee benefits and consulting firm, and
Horizon Consulting Group,  Inc., a firm specializing in commercial  policyholder
claim consulting services,  in 2000. In February 2001, Aon announced that it had
entered into a definitive agreement to acquire ASI Solutions Incorporated (ASI),
a  worldwide  provider  of  human  resources   administration  and  compensation
consulting  services.  The transaction  involves an exchange of Aon common stock
and is subject to regulatory approval and ASI shareholder approval.

      The Insurance  Brokerage and Other Services segment  consists  principally
of Aon's retail brokerage,  reinsurance,  wholesale and specialty  brokerage and
other related  services such as managing  underwriting  and claims and financing
services.  These  services are  provided by Aon Group,  Inc.,  its  subsidiaries
and certain other  indirect  subsidiaries  of the  Registrant  (the "Aon Group")
including  Aon Risk  Services  Companies,  Inc.;  Aon  Holdings bv; Aon Services
Group, Inc.; Aon Re Worldwide,  Inc.; Aon Limited;  Cananwill, Inc.; and Premier
Auto Finance, Inc.

      The  Consulting  segment  provides  a range  of  services  utilizing  four
practice groups:  employee  benefits,  compensation,  management  consulting and
employment   practices   outsourcing.   These   services  are  provided  by  Aon
Consulting Worldwide, Inc. which is also a subsidiary of Aon Group.

      Aon's Insurance  Underwriting  segment is comprised of supplemental  life,
accident  and health  insurance,  and extended  warranty and casualty  insurance
products.  Combined Insurance Company of America ("Combined  Insurance") engages
in the  marketing  and  underwriting  of life and accident and health  insurance
products.  Virginia Surety Company,  Inc. and London General  Insurance  Company
Limited offer extended warranty and casualty insurance products.

      On November 2, 2000,  the Registrant  announced a business  transformation
plan,  to be undertaken  from  November  2000 through the next fiscal year.  The
transformation  plan will affect each operating segment;  however,  most changes
will  affect  the  largest  operating  segment,  Insurance  Brokerage  and Other
Services,  and will occur in the major countries of operation,  the U.S. and the
United Kingdom.

      The Registrant hereby incorporates by reference  "Business  Transformation
Plan" on page 17 of the Annual Report to  Stockholders of the Registrant for the
Year 2000 ("Annual  Report"),  as well as pages 6 through 15, 20 through 24, and
pages 54, 55 and 59 of the Annual Report.



COMPETITION AND INDUSTRY POSITION

(1)  INSURANCE BROKERAGE AND OTHER SERVICES

      Aon Group, Inc; Aon Risk Services Companies, Inc.; Aon Limited (U.K.); Aon
Holdings International  bv;  Aon Services Group, Inc.;  Aon Re Worldwide,  Inc.;
Cananwill, Inc.; and Premier Auto Finance, Inc.

      Aon Group affiliated companies  conduct  the  Registrant's  brokerage  and
consulting  operations, and have 550 offices around  the world in 120 countries.
In 2000, those  companies  employed  nearly  40,000  professionals  and  support
personnel to serve the diverse needs of clients.

      Aon Group's retail brokerage  companies  operate in a  highly  competitive
industry  and  compete  with a large number of retail  insurance  brokerage  and
agency  firms  as  well  as individual brokers and agents and direct writers  of
insurance coverage. Those companies provide risk management services,  including
insurance placement and claims, loss control and administrative services as well
as  specialty  underwriting  solutions and  customized  products  and  services.
They  have  also  developed  certain  specialist areas such as marine, aviation,
directors  and officers liability, financial institutions, construction, energy,
media and entertainment.  In 2000, investments were made in professional talent,
technology,  process improvement and the development of specialized products and
services to meet the evolving needs of clients.  Those companies operate through
offices located in  North America, Europe,  Latin America, Africa, Australia and
Asia.

      Aon  Group's  companies  also  address  the  highly   specialized  product
development, consulting and administrative risk management needs of professional
groups, service businesses, governments,  healthcare  providers  and  commercial
organizations.  They also provides underwriting management  skills,  claims  and
risk management expertise, and third-party administration services to  insurance
companies, and insurance  brokerage  services for  individuals.  They market and
broker  both  the  primary  and   reinsurance  risks  of  these  programs.   For
individuals, associations and  businesses, affinity  products  for  professional
liability, life, disability income and personal lines are provided.

      Aon's reinsurance brokerage activities are organized under Aon Re  in  the
United States and Aon Limited in the  United  Kingdom, constituting the  largest
reinsurance broker in the world and offering  reinsurance,  analytical  services
and alternative risk financing vehicles.  The companies  serve  the  alternative
market with reinsurance placement, alternative risk services, captive management
services and catastrophe information forecasting.

      Premium-related financing services are available to clients of  Aon  Group
and other independent organizations through Cananwill. Certain retail automotive
organizations have also been provided a service which purchases a select  amount
of their auto financing and leasing contracts from individuals and sells them to
unaffiliated  parties  through  companies  associated with Premier Auto Finance,
Inc., which then continue the management of collections  on  the  contracts  and
provide other related services.  After March  27, 2001, contract  purchasing  by
companies associated with Premier Auto Finance, Inc. will no longer be generally
available, but service will continue on existing contracts with current clients.


(2)  CONSULTING

Aon Consulting Worldwide

      Aon Consulting Worldwide affiliated companies serve the  employee  benefit
needs of clients around the world.  Aon Consulting is one of the world's largest
integrated human resources consulting organizations.  Focusing on the increasing
demand  for  outsourcing solutions, Aon Consulting targets emerging  businesses,
IPOs,  recent mergers and acquisitions and corporations that  are  reengineering
staff functions.  The year 2000 acquisition of  ASA, an  employee  benefits  and
compensation consulting  firm, increased  Aon's  penetration of large  corporate
accounts.

      Around  the  world,  employee  benefits  markets  continue  to  change  as
companies  look for  better  ways to manage  their  human  capital  costs  while
expanding  the choices  offered to their  employees.  Aon  Consulting,  with its
expertise  in  employee  benefits,   compensation,   management  consulting  and
employment  practices  outsourcing,  and its  access to the  Registrant's  other
subsidiaries,   is   well-positioned   to  serve  this  market.  Aon  Consulting
subsidiaries  offer  services  to  clients  including  benefit  plan  design and
administration;  compensation  consulting  and surveys;  employee  selection and
assessment; process improvement; leadership development;  performance management
tools;   workforce   productivity  and  individual  and  organizational   change
management.  Benefits issues outside the U.S. are becoming more complicated, and
Aon Holdings and Aon Consulting  anticipate  increased demand for their services
in these markets.


(3)  INSURANCE UNDERWRITING

      Combined  Insurance Company of America  ("Combined  Insurance");  Combined
Life Insurance  Company of New York  ("CLICNY");  Virginia Surety Company,  Inc.
("VSC");  London General Insurance Company Limited ("London  General");  and Aon
Warranty Group, Inc. ("Aon Warranty").

      The Registrant's insurance underwriting  subsidiaries are part of a highly
competitive industry that serves individual consumers in North America,  Europe,
Latin  America and  Asia/Pacific  by  providing  accident  and health  coverage,
traditional  life  insurance  and   extended  warranties   through  distribution
networks, most of which are directly owned by the Registrant's subsidiaries.

<PAGE>
      The  supplemental  life  and  accident  and  health  distribution  network
encompasses  primarily  the  agents of  Combined  Insurance  and  CLICNY  (which
operates  exclusively  in  the  State  of New  York).  Combined  Insurance,  the
Registrant's  principal life and accident and health insurer,  has a sales force
of  several  thousand  career  agents  calling  on  individuals  to sell a broad
spectrum of low  premium  accident  and health  products.  Combined  Insurance's
current  product  portfolio  often  allows  policyholders  the  option of paying
premiums monthly through a  pre-authorized  check mechanism in the U.S. and on a
direct  debit  option  in the U.K.  Combined  Insurance  offers a wide  range of
accident-only  and  sickness-only   insurance  products,   including  short-term
disability,  cancer aid,  Medicare  supplement,  disability income and long-term
care   coverage.   Most  of  Combined   Insurance's   products   are   primarily
fixed-indemnity  obligations,  thereby not subject to escalating  medical costs.
Combined   Insurance  offers  a  simplified   accident  and  sickness  long-term
disability  policy.  Combined  Insurance  has expanded its product  distribution
through  payroll  deduction and their worksite  marketing  programs  continue to
develop.  Combined  Insurance's  business  is  conducted  in the United  States,
Canada, Latin America, Europe and Asia/Pacific.

      The  Registrant's  extended  warranty and  specialty  insurance  business,
conducted by VSC  subsidiaries in North America,  South America and Asia/Pacific
and  London  General in Europe,  is  composed  primarily  of  extended  warranty
insurance  products,  professional  liability  insurance  coverages and workers'
compensation  coverage.  VSC and London  General are among the  world's  largest
underwriters of consumer extended warranties. The extended warranty products are
sold in the United States, Canada, Latin America,  Europe and Asia/Pacific.  The
administration of certain extended warranty products on automobiles,  electronic
goods, personal computers and appliances is handled by certain operations in the
Insurance Brokerage and Other Services segment.


(4)  DISCONTINUED OPERATIONS

      The  Registrant  hereby  incorporates  by reference note 5 of the Notes to
Consolidated Financial Statements on page 40 of the Annual Report.


LICENSING AND REGULATION

      Regulatory  authorities  in the states or countries in which the operating
subsidiaries  of Aon Group  conduct  business may require  individual or company
licensing  to act as  brokers,  agents,  third  party  administrators,  managing
general agents,  reinsurance intermediaries or adjusters. Under the laws of most
states  in  the  United  States  and  in  most  foreign  countries,   regulatory
authorities have relatively broad discretion with respect to granting,  renewing
and revoking  brokers' and agents' licenses to transact business in the state or
country.  The manner of operating in  particular  states and  countries may vary
according to the  licensing  requirements  of the  particular  state or country,
which may  require,  among  other  things,  that a firm  operate in the state or
country through a local corporation. In a few states and countries, licenses are
issued only to individual residents or locally-owned  business entities. In such
cases,  Aon Group  subsidiaries  have  arrangements  with  residents or business
entities licensed to act in the state or country.

      Insurance   companies  must  comply  with  laws  and  regulations  of  the
jurisdictions in which they do business. These laws and regulations are designed
to ensure  financial  solvency of  insurance  companies  and to require fair and
adequate  service and  treatment  for  policyholders.  They are  enforced by the
states in the United States, by industry  self-regulating agencies in the United
Kingdom,  and by various  regulatory  agencies  in other  countries  through the
granting  and  revoking  of  licenses  to  do  business,  licensing  of  agents,
monitoring  of  trade  practices,  policy  form  approval,  minimum  loss  ratio
requirements,  limits on premium and commission  rates,  and minimum reserve and
capital requirements. Compliance is monitored by the state insurance departments
through periodic regulatory reporting procedures and periodic examinations.  The
quarterly and annual  financial  reports to the  regulators in the United States
utilize statutory  accounting  principles which are different from the generally
accepted  accounting  principles used in  stockholders'  reports.  The statutory
accounting  principles,  in keeping with the intent to assure the  protection of
policyholders  are based, in general,  on a liquidation  concept while generally
accepted accounting principles are based on a going-concern concept.

      The state insurance  regulators are members of the National Association of
Insurance  Commissioners  ("NAIC"). This Association seeks to promote uniformity
of, and to enhance the state  regulation  of,  insurance.  Both the NAIC and the
individual  states continue to focus on the solvency of insurance  companies and
their  conduct  in the  market  place.  This focus is  reflected  in  additional
regulatory  oversight by the states and emphasis on the enactment or adoption of
a series of NAIC model laws and regulations  designed to promote  solvency.  The
NAIC  revised  the  Accounting  Practices  and  Procedures  Manual  in a process
referred to as  Codification.  The revised manual is effective  January 1, 2001.
The domiciliary  states of Aon's major insurance  subsidiaries  have adopted the


<PAGE>
provisions  of the revised  manual.  The  revised  manual has  changed,  to some
extent,  prescribed statutory accounting practices and will result in changes to
the accounting practices that Aon's major insurance  subsidiaries use to prepare
their statutory-basis financial statements. The impact of these changes to Aon's
major  insurance  subsidiaries'  statutory  capital and surplus as of January 1,
2001 is not expected to be significant.

      Several  years ago, the NAIC  developed a formula for  analyzing  insurers
called  risk-based  capital  ("RBC").  RBC is  intended to  establish  "minimum"
capital  threshold  levels  that  vary  with  the  size  and mix of a  company's
business.  It is designed to identify companies with the capital levels that may
require  regulatory  attention.  RBC does not have any significant impact on the
insurance business of the Registrant.

      The state  insurance  holding  company  laws  require  prior notice to and
approval of the domestic state insurance department of intracorporate  transfers
of assets  within  the  holding  company  structure,  including  the  payment of
dividends by insurance company  subsidiaries.  In addition,  the premium finance
loans by Cananwill, Inc., an indirect wholly-owned subsidiary of the Registrant,
are subject to one or more of truth-in-lending and credit regulations, insurance
premium finance acts,  retail  installment sales acts and other similar consumer
protection  legislation.  Failure to comply  with such laws or  regulations  can
result in the temporary  suspension or permanent  loss of the right to engage in
business in a particular jurisdiction as well as other penalties.

      Recent federal and state laws and proposals  mandating  specific practices
by medical insurers and the health care industry will not, because of the nature
of  the  business  of  the  Registrant's  subsidiaries,  materially  affect  the
Registrant. Numerous states have had legislation introduced to reform the health
care  system and such  legislation  has passed in  several  states.  While it is
impossible  to forecast  the precise  nature of future  federal and state health
care changes,  the  Registrant  does not expect a major impact on its operations
because  of the  supplemental  nature  of most  of the  policies  issued  by its
insurance  subsidiaries  and because the coverages  are  primarily  purchased to
provide,  on  a  fixed-indemnity  basis,   protection  against  loss-of-time  or
disability  benefits.  Congress has passed the Financial Services  Modernization
Act commonly known as S 900 or the Gramm,  Leach,  Bliley Act. While S 900 makes
substantial  changes in  allowing  financial  organizations  to  diversify,  the
Registrant  does not believe the enactment of S 900 will have a material  effect
on the business of its insurance subsidiaries.


CLIENTELE

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


EMPLOYEES

      The Registrant's  subsidiaries had  approximately  51,000 employees at the
end of 2000 of whom  approximately  43,000 are salaried and hourly employees and
the remaining  8,000 are sales  representatives  who are  generally  compensated
wholly or primarily by commission.


ITEM 2.  PROPERTIES.

      The  Registrant's  subsidiaries  own and occupy  office  buildings in four
states and certain  foreign  countries,  and lease office space elsewhere in the
United  States and in various  foreign  cities.  Loss of the use of any owned or
leased property, while potentially disruptive,  would have no material impact on
the Registrant.


ITEM 3.  LEGAL PROCEEDINGS.

      The Registrant  hereby  incorporates  by reference note 14 of the Notes to
Consolidated Financial Statements on page 53 of the Annual Report.

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

      None.

                                 Aon Corporation
                                (Parent Company)
                     NOTES TO CONDENSED FINANCIAL STATEMENTS



(1)   See notes to consolidated  financial statements  incorporated by reference
      from the Annual Report.

(2)   Generally,  the net assets of Aon's insurance  subsidiaries  available for
      transfer  to the  parent  company  are  limited  to the  amounts  that the
      insurance  subsidiaries'  statutory  net assets exceed  minimum  statutory
      capital  requirements;  however,  payments of the amounts as  dividends in
      excess  of  $197  million  may  be  subject  to  approval  by   regulatory
      authorities.

(3)   In 1998,  Aon  guaranteed  a committed  bank credit  facility  under which
      certain  European  subsidiaries  can  borrow  up to EUR  400  million.  At
      December  31,  2000,   loans  of  EUR  279  million  ($260  million)  were
      outstanding under this facility.

      An indirect  wholly-owned  subsidiary of Aon  Corporation  manages various
      investment portfolios, totaling $247 million at December 31, 2000, held in
      a collateral trust for the benefit of certain unaffiliated entities and is
      obligated to produce  specified  investment  returns for those portfolios.
      Aon  Corporation  has  unconditionally  guaranteed the obligations of this
      subsidiary.

(4)   In 2000,  the  Condensed  Statements  of Cash Flows  exclude the impact of
      certain  non-cash  transfers  primarily  related to notes  receivable from
      subsidiaries and notes payable to subsidiaries.

executive officer on two days' notice to each director,  either personally or by
mail or by telegram.  Special meetings of the board of directors shall be called

      ---------  ------
incorporation  or by  statute,  at all  meetings  of the  board of  directors  a
majority  of the  directors  then in office  shall  constitute  a quorum for the
transaction of business, except that in no case shall less than one-third of the
total number of directors as determined by the certificate of incorporation  and
these  by-laws  constitute  a quorum.  The act of a  majority  of the  directors
present at any meeting at which there is a quorum  shall be the act of the board
of  directors.  If a quorum  shall not be present at any meeting of the board of
directors,  the directors  present  thereat may adjourn the meeting from time to
time,  without  notice other than  announcement  at the meeting,  until a quorum
shall be present.

      Section 9. Action by written consent.  Unless otherwise  restricted by the
      ---------  -------------------------
certificate of incorporation or these by-laws,  any action required or permitted
to be taken at any meeting of the board of directors or of any committee thereof
may be taken without a meeting, if all members of the board or committee, as the
case may be, consent  thereto in writing,  and the writing or writings are filed
with the minutes of proceedings of the board or committee.

      Section  10.  Committees  of  directors.  The  board of  directors  may by
      -----------   -------------------------
resolution  passed by a  majority  of the whole  board  designate  an  executive
committee and one or more other committees,  each committee to consist of one or
more directors of the corporation. The board may designate one or more directors
as alternate members of any committee who may replace any absent or disqualified
member at any meeting of the committee.  In the absence or disqualification of a
member of a committee, the member or members thereof present any meeting and not
disqualified  from voting,  whether or not he or they  constitute a quorum,  may
unanimously  appoint  another  member  of the board of  directors  to act at the
meeting in the place of any such absent or disqualified member.

Achieving any vision demands CHANGE.

But with change comes RISK.



The solution:  ANTICIPATE,  UNDERSTAND AND EMBRACE RISK. SEIZE THE OPPORTUNITIES
that taking new risks can bring and realize the benefits.



THIS IS NOT A SMALL CHALLENGE.

As the  complexity  of risk expands at an  ever-increasing  pace,  it demands an
almost  constant  stream  of  innovative  thinking.  Globalization,  e-commerce,
threats  to  intellectual  property,  vulnerability  of brands  and  reputation,
competition for talent, product failures, economic uncertainty -- it's a growing
list.

No company  faces a single set of risks for more than a short period of time. It
is a continuum,  changing and evolving with an organization's  growth,  markets,
strategies and competitive threats.

Winning in this environment  requires an advocate, a trusted advisor to help you
navigate through these challenges -- applying experience, skills and presence --
to be there with you -- how, where and when you need them.

Aon IS THE RIGHT CHOICE.

We have become leaders in our industry by  continually  evolving for the benefit
of  our  clients.  Demands  for  global  distribution,  integrated  fulfillment,
outsourcing  solutions,  human capital  management advice,  innovative  consumer
insurance products and e-commerce  solutions drove us to invest in acquisitions,
product research and development, new expertise and new technologies.

Now,  we are  engaged  in a business  transformation  that will  elevate  client
service to even higher levels,  improve career  opportunities  for employees and
increase returns for stockholders. But we will not stop there, because at Aon...

we are here to INSURE YOUR VISION.

                                     - 1 -
<PAGE>
MESSAGE TO STOCKHOLDERS

During 2000, we made several important changes that I believe will be pivotal to
our future success.  On the following pages, I will share my view of Aon's past,
and more importantly, Aon's future.

In 2000, we did not achieve our overall financial goals. Before special charges,
earnings  per  share  were  $2.01   compared  with  $2.07  in  1999,  the  first
year-over-year   decline  in  Aon's   history.   Clearly,   these   results  are
disappointing to me, to my fellow employees and to you, our fellow stockholders.

The primary cause of the earnings per share decline was lower investment  income
in our non-operating  corporate  segment.  Corporate segment revenue dropped $93
million,  representing  $0.23  per  share.  This  was due in  part to  valuation
declines in the equity  markets.  Longer-term,  we expect these  investments  to
provide favorable returns.

When  we  look  more  closely  at  the  underlying  financial performance of our
operating  businesses, we see steady improvement in 2000 driven by strong client
satisfaction  and a growing demand for our services and products.  In fact,  all
three of our  operating  segments reported  increased revenues and pretax income
versus 1999.

Looking ahead, I am very optimistic.  We took several decisive steps in 2000 all
building on the global  foundation  that we have  created  over the last several
years. We strengthened our executive management team, installed industry-leading
technology  platforms  and  initiated a major  business  transformation  plan. I
believe  these actions will  significantly  improve our  performance  in 2001 --
advancing our client  franchise,  improving career  opportunities  and enhancing
returns for our stockholders.

Aon's STRATEGY -- MEETING THE CHANGING NEEDS OF OUR CLIENTS
Aon's clients face change every day to achieve their vision for their customers,
their  stockholders  and their  employees.  They must,  to keep pace with global
competition,  changing economies, industry challenges and new competitive forces
such as e-commerce.  Aon plays a critical role in this process, working together
with  clients as they take on new risks,  increasing  the odds that  change will
create new value.

Aon also has faced  change to achieve its vision of  continually  improving  the
quality of solutions  delivered to clients.  Investments  in  acquisitions,  new
technologies  and intellectual  capital,  as well as the  implementation  of new
business  processes,  are some of the major changes that Aon has undertaken over
the last several years.

We believe the benefits of our decisive  steps and the  intrinsic  value that we
have created will become even more evident as 2001  unfolds.  We have a powerful
worldwide  professional  services  organization,  global  access to capital  and
distribution  channels,  unparalleled risk management  expertise,  a growing and
more profitable consulting practice and a unique consumer policyholder base.

Looking at our external  environment,  we see deregulation and  privatization as
growing global trends that will increase  demand for our services.  In addition,
we are seeing the first  broad-based  premium  rate upturn in the  property  and
casualty  insurance  cycle in more  than a  decade.  Heightened  competition  is
forcing more companies to outsource functions beyond

                                     - 2 -
<PAGE>
their core competencies.  Historically low unemployment coupled with the growing
presence of service  companies are escalating the importance of human capital as
the key competitive advantage.

Aon anticipated these trends and developed business strategies around them.

REVIEW OF OPERATING SEGMENTS
In 2000,  Aon's  combined  operating  segments -- insurance  brokerage and other
services, consulting and insurance underwriting -- recorded pretax income growth
of 12% before special  charges.  Strong organic revenue growth was driven by new
client relationships, enhanced client retention and improved productivity.

International  brokerage,   alternative  market  operations,   managing  general
underwriting,  and  wholesale  and  reinsurance  brokerage  each  produced  good
financial  results in 2000.  Claims services posted excellent organic growth and
we secured  significant  outsourcing  contracts  with  insurance  carriers.  Our
affinity programs for nurses,  accountants and other professionals increased the
amount of product offerings.  And, we announced a major new business opportunity
with State Farm, the largest U.S. personal lines insurer,  tapping our specialty
property and casualty expertise for the benefit of their agents' customers.

We made several  executive  management  changes during the year in our brokerage
segment.  Ken  LeStrange,  who headed our  alternative  market  operations,  was
promoted to lead  retail  brokerage  for the  Americas.  Max Taylor,  the former
chairman  of  Lloyds,  joined  us to  head  relationship  management  for  large
multi-national accounts.

Consulting  posted its best financial  performance ever under the new leadership
of Don Ingram who was promoted to head worldwide  consulting at the beginning of
2000.  Revenues  grew 17% and pretax  income jumped 36%. The demand for talented
employees continues to create increasing needs for our consulting services.

In October 2000, we completed our acquisition of Actuarial Sciences  Associates,
Inc. giving us greater strength with large corporate  accounts in our consulting
segment,  as well as a broader array of retirement  planning  products.  We also
have developed  e-commerce  solutions that allow corporate clients' employees to
research,  plan, purchase and enroll in insurance and financial products on-line
that match their individual risk preferences.

Consumer demand for Aon's accident,  health, life and warranty products advanced
in 2000.  Insurance  underwriting  revenues  approached  $2.2  billion and prior
investments in new business development initiatives showed good progress.

BUSINESS TRANSFORMATION PLAN
On November 2, 2000, we announced our business  transformation plan. The purpose
of the plan is to elevate  service and  productivity  to even higher levels that
anticipate the changing and growing needs of our clients.

Through our  acquisitions  and  consolidations,  we have brought  together  many
companies  over several  years.  A common  culture now exists  around a unifying
principle of striving to exceed client  expectations.  As we acquired  companies
and assimilated  cultures,  we  simultaneously  invested in new  technologies to
ensure that we would stay on the leading edge,  giving our employees and clients
the best tools possible.

Business  transformation  was the next logical step.  We had a choice.  We could
make  improvements  at the margin,  or we could  rethink and  redesign how we do
business.  We concluded that incremental change yields incremental  progress and
decided that the only viable option was to undertake fundamental change.

We are realigning leadership,  technologies,  business models and organizational
structures.  The transformation  plan encompasses each of our operating segments
and staff  functions.  Most of the change  will occur in our  largest  operating
segment,  insurance brokerage, and in our major countries of operation, the U.S.
and U.K. We will maintain  client  service at the local office  level,  where it
belongs,  but move administrative  functions to processing  centers,  freeing up
more management time for consultation with clients.

We expect to save $150  million to $200  million in  expenses  per year from the
business  transformation  plan  and we  anticipate  the  savings  to  reach  the
annualized  level starting in fourth quarter 2001. Total pretax costs attributed
to the  transformation are expected to be between $250 million and $325 million,
most of which will be recorded as a special charge.

The plan is on track. We recorded an $82 million pretax special charge in fourth
quarter 2000. The remaining  special  charges will be incurred in the first half
of 2001. While we will achieve  significant  savings,  the real objective of the
transformation  plan is to facilitate  stronger  organic growth by creating more
scalable operating  platforms that enhance client service.  Improved job design,
career planning and compensation  programs are also being  implemented to better
align employee activities with financial objectives. Employee ownership of Aon's
common shares is already high.  These actions will tie employee and  stockholder
interests even more closely together.

A major  technological  accomplishment  in  2000  was the  U.S.  rollout  of our
proprietary  policy  management and accounting  system. It is the foundation for
much of our business  transformation  plan. The inherent flexibility of this new
system allows us to redesign processes and organizational  structures to enhance
marketing,   client  service,  new  product  development  and  overall  workflow
productivity.  Additional  rollouts  of the system  will  continue  this year in
Canada and parts of Europe. We also have linked this new system with our AonLine
client software to leverage the benefits of both.

A more scalable and robust e-commerce platform infrastructure is near completion
and will be ready to  accept  new  applications  during  the  year.  ARENA,  our
reinsurance  information technology platform,  will be expanded from the U.S. to
international  locations and our document management system efforts will also be
leveraged more widely.

We have  instituted  a country  management  model in the U.K.  that we have used
successfully in other parts of the world to drive down infrastructure  costs and
to enhance  integrated  business  development across operating  segments.  Major
steps already completed include outsourcing agreements for

                                     - 4 -
<PAGE>
information  technology  and  facilities  management  involving  the transfer of
hundreds of employees.  Both will reduce costs and enhance service levels. Staff
functions such as human resources,  accounting and legal have been  consolidated
into  single  units  in the  U.K.  to  support  all  businesses.  We  have  also
streamlined our subsidiary  structure in the U.K. by consolidating  the majority
of our operations under one entity, Aon Limited.  This will lower regulatory and
administrative costs and also facilitate better management of working capital.

Overall, the business transformation plan is off to a good start. I am confident
that it will  deliver on the  tremendous  potential  that we have built over the
past several years.  We have come a long way in turning  several  companies into
one  leader.  We now can focus on  becoming  the best  operating  company in our
industry by driving continuous  improvement;  making all of Aon more accessible,
streamlined and organized around our clients.

In November 2000, we were  fortunate to welcome Robert S. Morrison,  chairman of
The Quaker Oats Company,  to our board of directors.  Newt Minow and Dan Carroll
will be leaving  Aon's  board of  directors  in April 2001 having  attained  our
mandatory  retirement  age.  We greatly  appreciate  their  years of service and
helpful guidance.

LOOKING AHEAD
The  property  and  casualty  insurance  markets are  experiencing  premium rate
increases in virtually  every line of insurance.  We see this trend  continuing,
given the deteriorating underwriting results of many insurers and
reinsurers.  We stand ready to secure the best options possible for our clients,
including extensive alternative risk transfer solutions,  in this more difficult
environment.

Aon's  strategy has always been driven by the belief that a strong  client focus
will result in increased  stockholder value. Aon's client base spans the Fortune
500, the FTSE 100, thousands of middle market and smaller commercial  companies,
millions of individual  policyholders,  the world's largest insurance  companies
and  thousands  of  independent  agents  and  brokers  who  tap  into  our  vast
capabilities  every day. Our global  infrastructure of resources,  relationships
and people  cannot be  replicated.  We  benefit  from an  extremely  diversified
earnings stream that affords us significant financial strength.

A timely and effective  implementation of our business  transformation plan is a
major  focus  for 2001.  The  success  of this  plan will  allow us to reach our
business  development and productivity  goals, as well as our overall  financial
goals of  double-digit  earnings per share  growth and improved  returns for our
stockholders.

We  have  built  a  world-class  professional  services  organization  and  I am
confident  that the true value of our  franchise  will become more evident as we
successfully execute our business plans and our strategies.

Sincerely,


/s/Patrick G. Ryan

Aon: A Client-Centric Approach

Business management and risk management are inseparable  items at the top of any
strategic  agenda.  The reason:  an  amazing  broadening of the  definition  and
concept of risk.  It now  extends  to the reputations  of companies and  brands,
intellectual  property,  unforeseen  competition,  attraction  and retention  of
talent -- it's a long and evolving list.

                                     - 6 -
<PAGE>
We create innovative  solutions that address the changing risks our clients face
as they seek out new opportunities.

                                     - 7 -
<PAGE>
The  new  demands  of risk  have  far  surpassed  the  scope  and  abilities  of
traditional  insurance  offerings.  The new  model  demands  an  advisor  with a
client-centric  view and the  ability to  replace  off-the-shelf  policies  with
programs which are custom-fit to each client's specific needs.

It requires  an  ally  with  a holistic view  of risk, more an  advocate  than a
supplier, to help clients first understand the  new dimensions  of risk and then
combine their  experience with Aon's global  distribution network and innovative
fulfillment capabilities.

      Chief Operating Officer


"WE APPLY A CLIENT-CENTRIC APPROACH TO A WORLD OF RISK, BACKED BY THE EXPERTISE,
TEAMWORK AND ENERGY OF AON'S PROFESSIONALS AROUND THE WORLD."


Aon's business model applies  segmentation  and  specialization  to solve client
needs.  First,  in  collaboration  with our  clients,  we evaluate  their needs,
complexity, industry profile, geographic scope and other characteristics.  Then,
we have our specialists apply their intellectual  capital:  industry  knowledge,
product expertise,  market intelligence and other strengths.  Finally, the right
solution is created from our full slate of products and services, including risk
management,  global brokerage,  alternative risk transfer,  captive  management,
claim  services,   affinity,   managing  general  underwriting,   human  capital
consulting and consumer insurance and warranty protection.

Overlaying this model is a discipline of strategic  account  management where we
join forces with our  clients to  understand  their  business  goals,  financial
objectives, competition, core strengths,  vulnerabilities and new opportunities.
Based on this  understanding,  we provide  solutions  in the most  comprehensive
manner possible.


We also have created  worldwide  practice  groups that are connected by a global
account  management system so that we can tap into the most  sophisticated  risk
solutions,  no matter where they were created.  An industry expert in Europe can
access a  recently  updated  development  in the U.S.  and  deliver  a  solution
seamlessly to a client in Asia.

We also can help put the overall risk profile into perspective.  For example, we
use dynamic  financial  analysis to assess the financial  impact of various loss
scenarios.  This can uncover  that a client may be  over-protected  in one area,
dangerously  under-protected  in  another  and  possibly  unaware of a major new
hazard.

Together,  these  capabilities  allow us to collaborate with clients to evaluate
risk on an enterprise basis and then apply comprehensive solutions which deliver
Aon's vast  resources.  We apply a  client-centric  approach to a world of risk,
backed by the expertise,  teamwork and energy of Aon's professionals  around the
world.

On the following pages,  we  look at three representative companies  that depict
challenges  Aon has  addressed  for  clients.  First,  a fast-paced  Fortune 100
company;  second,  a spin-off  dealing  with a dramatic change of direction; and
third, an international  company where risk takes on a global scope.

In  each,  we  illustrate   how  Aon  helped  the  company  take   advantage  of
opportunities that risk brings in terms of creating value.

UNCOVERING RISK.
WHAT YOU DON'T KNOW CAN HURT YOU.

A MAJOR SHIPPING COMPANY ASKED FOR HELP IN CUTTING CLAIMS FREQUENCY. THAT'S WHEN
THINGS GOT INTERESTING.

Like many  companies  that have been good enough,  long enough to break into the
Fortune 100, the client had successfully cleared many hurdles.

But there was a  problem.  The  company's  management  felt  that  their  claims
frequency  was out of line.  They needed  help.  What they didn't know was their
long-time  comfort level with the risk they perceived no longer matched the risk
they faced.  An  understandable  situation  when every waking hour is focused on
managing a fast-paced business.

For Aon, a request to help in one area is usually  just a first  step.  Once our
loss control and claims experts helped reduce worker injuries, we put together a
team that could  consult with the  company's  management  to address risk in its
many forms.

We completed an enterprise risk management analysis, from transportation risk to
corporate governance to intellectual  property.  Our risk assessment team worked
hand-in-hand  with the client looking at catastrophe risk exposures and recovery
plans,  retention of key talent,  occupational and environmental  health hazards
and the full range of risk.

Our strategic account manager found better ways to transfer,  retain and finance
operational risk. Alternative risk transfer solutions were developed and captive
management programs were deployed.

The company felt comfortable that it had adequate  coverage for physical damage,
but the  definition  of disaster  expanded due to their  growing  dependence  on
technology.  While they had insured against the cost of replacing systems,  they
did not have adequate disaster recovery plans and had  underestimated  the costs
when an information-dependent company loses access to data.

We  showed  the  client  cases in which  catastrophes  that  cost in the tens of
millions of dollars in direct equipment damage can generate indirect losses that
can reach  hundreds  of millions of  dollars,  not to mention  lost  opportunity
costs. We recommended parallel systems, comprehensive disaster recovery planning
and decentralized authority to act as soon as disaster strikes.

The result:  a successful  company now has an enhanced risk  management  program
that addresses an expanded view of risk.

INDEPENDENCE DAY.
A NEWLY PUBLIC COMPANY CONFRONTS A WHOLE NEW WORLD OF RISK.

BEING SPUN OFF AS A SEPARATE COMPANY DOESN'T HAPPEN IN A DAY. IT JUST FEELS THAT
WAY.

A company's  stock price is lagging its peers' and the answer to unlock value is
to spin off one or more of the  valuable  parts.  They will have more freedom to
compete and the market will be able to value them as pure plays.

All of a sudden,  a business  accustomed  to  operating  under one set of rules,
finds itself living under new ones. Change and risk become one.

The newly spun off client  found  itself  looking at risk in a whole new way. It
was not something for the parent  company to decide and the division to execute.
The  responsibility  for risk very  quickly  moved up the  agenda of  leadership
concerns.

In many  ways,  especially  concerning  risk,  a  spin-off  is like a  start-up.
Facilities  and fleet  coverage,  workers'  compensation,  errors and omissions,
independent contractor programs, a new board of directors, intellectual property
- -- it's a full slate. There are new demands to attract and keep the best people.
There  are  employee  benefits  and  savings  plans  to  be  created.  It  needs
independent  access to  affordable  protection  to fund growth.  Most of all, it
needs a plan.

With a company this "new",  growing this fast, and with cash flows more seasonal
and  unpredictable   than  the  parent  company's,   our  approach  centered  on
flexibility.  Aon helped create a long-term comprehensive plan that consolidated
the individual risk profiles for all the new company's units, with data combined
in a centralized  risk  information  warehouse so that it could be analyzed on a
portfolio  basis.  The risk  management  process  became an integral part of the
strategic  business and capital planning process as the new company continued to
add units through acquisitions and remove others through divestitures.

In the  course of the  planning,  Aon  stepped  in with a number of  specialized
resources.  Aon's mergers and acquisitions specialists provided advice regarding
acquisition targets and off balance sheet risks. Our loss prevention specialists
also found ways to reduce certain manufacturing costs.

The uncertainties  that come from a changing  organization also raise the threat
of a severe talent drain.  So the client turned to Aon's  consultants to develop
compensation and reward programs that balance the bottom line  considerations of
a newly public company with the needs of talented employees. That engagement led
to a broader effort to make certain that the company was  adequately  staffed in
key positions and that there was a development  plan in place to ensure that the
talent pipeline would meet future needs.

As the company's  business needs grow, the risk  management plan that Aon helped
them develop will ensure that the issues are addressed,  that protections are in
place and that flexibility will promote growth.

CROSSING BORDERS.
GLOBAL BUSINESS MEANS GLOBAL RISK.

Risk management on a  global  basis  demands  worldwide  services  and a  broad
perspective.

Aon's client, a rapidly growing  communications  company with global operations,
found  itself  with a  patchwork  of  credit  policies  housed  in  its  various
subsidiaries.  Maybe  they were fine as is but maybe  these  policies  should be
consolidated.  The client called in Aon to help them find the answer and to take
the right action to make sure their policies  balanced  growth with exposures in
markets  where the  opportunity  is often  matched  by  economic  and  political
uncertainties.

The  credit-worthiness  of  customers  country to country is one of  hundreds of
considerations  that any organization  operating across borders must factor into
their risk profile.

Employee benefits  expectations and laws vary widely. There is often the risk of
a myriad  of  catastrophes,  from  earthquakes  to  terrorist  acts.  There  are
significant  fleet risks in moving goods through  countries  with widely varying
infrastructure  and  safety  standards.  Issues  can be  different,  not just by
country, but by region within countries.

The client  turned to Aon for two  reasons.  One was the wide range of available
services and coverages.  But just as important was Aon's global service approach
which brings  together  resources  and people from around the world to make sure
the client has the right protection and the right service wherever they need it.

Aon's  international  trade credit team helped the client  understand the credit
insurance market.  They pointed out the information and underwriting  advantages
of buying  coverage  locally and how to take advantage of the  consolidation  of
markets.  They reviewed the pluses and minuses of the various forms of insurance
available in different  countries.  They showed how Aon can coordinate purchases
on a global basis with  numerous  companies  to ensure the best policy  service.
That led to a full audit of the client's trade insurance policies, which in turn
produced the green light for a full program of coverage.

This  engagement led to the client  inviting Aon to review the risks it faced in
varying  political  situations  ranging  from  confiscation  to  the  threat  of
terrorism.  As the  company  acquired  new  businesses,  it also called on Aon's
international  benefits unit to coordinate a workable benefits  structure across
economies and cultures.

The client now has more  latitude  to focus on the  global  complexities  of its
business, while Aon helps deal with the complexities of risk.

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

This management's  discussion and analysis of financial condition and results of
operations  contains  forward-looking  statements as that term is defined in the
Private  Securities  Litigation Reform Act of 1995. See "Information  Concerning
Forward-Looking Statements" on page 28 of this annual report.

GENERAL
Aon has three  operating  segments:  Insurance  Brokerage  and  Other  Services,
Consulting and Insurance  Underwriting.  These segments are based on the type of
client  and  the  services  or  products  delivered.  Aon  also  has  a  fourth,
non-operating segment, Corporate and Other.

References to organic growth exclude the impact of  acquisitions,  dispositions,
transfers,  investment income, foreign exchange and other unusual items. Written
premiums  are the  basis  for the  measurement  of  organic  growth  within  the
Insurance Underwriting segment.

References to income before income tax are before minority  interest  related to
the  issuance of 8.205%  mandatorily  redeemable  preferred  capital  securities
(capital  securities)  (see  note 10) and the  cumulative  effect of a change in
accounting principle (see note 1).

The  accounting  policies  for the  business  segments  are  identical  to those
described in note 1 to the consolidated financial statements.

SPECIAL CHARGES
GENERAL
Aon's  special  charges are  reflected in general  expenses on the  consolidated
statements  of  income.  Aon's  unpaid  liabilities  relating  to  the  business
transformation  plan,  special charges and purchase  accounting are reflected in
general  expense  liabilities  on  the  consolidated   statements  of  financial
position.

2000
BUSINESS TRANSFORMATION PLAN
In  November  2000,  Aon's  Board  of  Directors  approved,   in  principle,   a
comprehensive  business  transformation plan designed to enhance client service,
significantly  improve the way Aon conducts  business and improve  profitability
primarily through utilization of technology and process redesign.

Implementation of the business transformation plan began in fourth quarter 2000.
Aon will incur costs  estimated to be between $250 million and $325 million on a
pretax  basis  comprised  of both  special  charges and  transition  costs.  The
majority of the special charges,  which constitute the largest part of the costs
of the  business  transformation  plan,  are  expected to be taken by the end of
first quarter 2001 with the remaining  amount to be recognized in second quarter
2001.  By  third  quarter  2001,   transition  costs  are  expected  to  decline
significantly.  The  majority  of the plan costs and  savings are related to the
Insurance  Brokerage and Other Services segment  principally in the U.S. and the
U.K., where most of Aon's offices and employees are located. The majority of the
charges  involve cash outlays  primarily  for  severance  payments for workforce
reductions relating to the elimination of about 3,000 positions or approximately
6% of Aon's 51,000 total worldwide workforce as of December 31, 2000.  Positions
being  eliminated  involve all levels  including  senior and middle  management,
staff functions, administrative and clerical positions.

The first phase of the plan resulted in the  elimination  of  approximately  500
positions.  Aon's total  employee  headcount  as of December 31, 2000 grew by 2%
compared to prior year-end due to significant  new business  opportunities,  the
Actuarial  Sciences  Associates,  Inc. (ASA)  acquisition (see note 3) and other
smaller acquisitions.

In connection  with the plan, Aon recorded pretax special charges of $82 million
($50 million  after-tax or $0.19 per share)  during  fourth  quarter  2000.  The
special charges  included costs related to termination  benefits of $54 million,
other costs to exit an activity  of $6 million and asset  impairments  and other
charges of $22 million  relating  primarily  to the  abandonment  of systems and
equipment (see note 4).

Transition costs,  primarily  related to the running of parallel  systems,  were
nominal in fourth  quarter 2000 and are projected to offset savings in the first
half of 2001.  Pretax special charges and transition  costs in the range of $170
million to $240 million are projected to be incurred as the plan continues to be
implemented.

Annualized  pretax savings from the plan are estimated to be approximately  $150
million to $200  million.  Full  annualized  run rate savings are expected to be
achieved in fourth  quarter  2001. As expected,  savings in fourth  quarter 2000
were not appreciable.  As Aon progresses through the next several quarters, more
business process change and a significant increase in position eliminations will
drive cost savings.  Temporary pressure on revenue growth rates may occur during
the implementation of the plan.

1999
In first  quarter  1999,  Aon recorded  special  charges of $163  million  ($102
million  after-tax  or $0.39 per share).  The charges  included  provisions  for
restructuring  in the  Insurance  Brokerage  and Other  Services and  Consulting
segments of $120 million (see note 3). Also, in the Consulting segment,  charges
of

                                     - 17 -
<PAGE>

$43 million were recorded in first quarter 1999 to reflect  amounts  required to
compensate customers who switched out of company pension plans in the U.K. based
upon advice  offered by  financial  advisors of current Aon  subsidiaries.  This
advice was given prior to Aon's purchase of these companies (see note 14).

In  fourth  quarter 1999,  Aon  recorded  special  charges of  $150 million ($93
million after-tax or $0.35 per share).  These charges reflect an  additional $78
million  related to the  pension  payments  described above following changes in
U.K.  government  requirements and  $72 million relating to  various  litigation
matters including Unicover (see note 14).

Aon anticipates the settlement of the liabilities  relating to the U.K.  pension
selling  to be  disbursed  over the next few years.  A portion  of the  Unicover
matter was settled in early 2000. The remaining Unicover issues are complex and,
therefore,  the timing and amount of  resolution  cannot be  determined  at this
time.

CONSOLIDATED RESULTS FOR 2000 COMPARED TO 1999
REVENUE
On a comparable  currency basis, total 2000 revenue of $7.4 billion rose 7% over
1999.  On a reported  basis,  total  revenue  increased 4% in 2000 compared with
1999.  This  increase was largely  attributable  to new  business  growth in the
operating segments,  business  combination  activity and the impact of improving
premium rates across the property and casualty insurance markets. Revenue growth
was negatively  impacted by unfavorable  foreign exchange rate comparisons,  the
absence of Unicover  revenue and a  significant  decrease in corporate and other
investment revenues associated with lower income on disposals of securities. Aon
does not hedge revenues  against foreign  currency  translation  since it is not
cost effective,  but does attempt to hedge pretax income.  Consolidated  revenue
for all segments grew approximately 8% on an organic basis over 1999.

Consolidated revenue by geographic area follows:


(millions)   Years ended December 31       2000        1999        1998
- ------------------------------------------------------------------------

  Total revenue                         $ 7,375     $ 7,070     $ 6,493
- ------------------------------------------------------------------------

U.S. consolidated revenue,  which represents 59% of total revenue,  increased 5%
in 2000 compared to 1999, largely attributable to organic growth and acquisition
activity.  U.K. and Continent of Europe revenue combined  increased  slightly to
$2.2 billion and Rest of World revenue increased 11% to $829 million  reflecting
acquisitions and new business.

Brokerage  commissions  and fees  increased 7% to $4.9 billion,  primarily  from
organic growth of new business and from business combination activity. Partially
offsetting the growth was the negative impact of foreign exchange rates.

Premiums  and other  increased  4% in 2000 to $1.9  billion.  This  increase was
generated by continued  strong growth in the accident and health core businesses
driven by the  continued  expansion  of product  distribution  through  worksite
marketing programs and the development of new product initiatives  introduced in
1999 on a global basis.  Revenue  growth was partially  offset by a reduction in
extended warranty revenues primarily from the intentional discontinuation of one
major warranty renewal and the loss of revenue from the exit of a major retailer
from the appliances and electronics line.

Investment  income of $508 million declined 12% in 2000  principally  reflecting
lower levels of income on disposals of  securities.  This decline was  partially
offset  by higher  investment  income  from the  insurance  brokerage  and other
services and consulting  operations,  which increased $30 million or 19% in 2000
compared to 1999.  Higher  short-term  interest rates coupled with improved cash
flows also contributed to the increase.

                                     - 18 -
<PAGE>

EXPENSES
General expenses,  excluding special charges,  increased $207 million or 4% over
1999, primarily reflecting investments in new business initiatives, acquisitions
and technology.  Such costs included the rollout of Aon's U.S. retail  brokerage
computer system platform and related  conversions,  running of parallel  systems
and one-time training expenses.

Benefits to  policyholders  increased 7% in 2000 and exhibited no unusual claims
activity.

Interest  expense   increased  33%  from  prior  year  partly   attributable  to
acquisition  financing.  Higher  short-term  interest rates and the issuances of
$250  million of 6.9%  notes in second  quarter  1999 and $250  million of 8.65%
notes in second quarter 2000 (see note 7) also contributed to the increase.

INCOME BEFORE INCOME TAX
Excluding special charges, income before income tax decreased $12 million or 1%,
primarily reflecting lower levels of income on disposals of securities, costs to
integrate Aon's global network,  additional  interest expense and the absence of
Unicover  revenue.  During the year, the net foreign  exchange  impact to pretax
income, after the benefit of derivative activity, was negligible.  Approximately
47% of Aon's  consolidated  income before income tax and special charges is from
non-U.S. operations.

CONSOLIDATED  RESULTS FOR FOURTH QUARTER 2000 COMPARED TO FOURTH QUARTER 1999
On a comparable currency basis, total revenues in the quarter increased 8%. On a
reported basis,  revenue increased 4% to $2 billion primarily reflecting organic
growth from increased new business and business combination activity, the impact
of premium rate increases and additional new business. Total expenses, excluding
special  charges,  increased  2% to $1.7  billion for the quarter as a result of
acquisitions  and related  costs and  investments  in new business  initiatives.
Income  before  income  tax,  excluding  fourth  quarter  2000 and 1999  special
charges,  increased $56 million or 29% to $246  million.  The increase in pretax
income before special charges  primarily  reflects the effects of strong organic
growth and expense controls offset by decreased revenues on equity investments.

CONSOLIDATED RESULTS FOR 1999 COMPARED TO 1998
REVENUE
On a comparable  currency basis, total revenue growth was 10%. Total revenue was
$7.1 billion,  an increase of 9% on a reported basis.  This increase was largely
attributable to growth in brokerage commissions and fees resulting from business
combination activity, growth in insurance premiums from new business and organic
growth in the operating segments. Negative foreign exchange translations,  lower
interest  rates  and lower  corporate  investment  income  on equity  securities
negatively  impacted  revenue  growth.  Consolidated  organic revenue growth was
approximately 5% over 1998.

U.S. revenues  increased 11% in 1999 compared to 1998 primarily due to increased
new business and acquisitions.  U.K. and Continent of Europe revenues  increased
8% to $2.2  billion and Rest of World  revenue of $746  million  increased 3% in
1999 from acquisitions and new business.

Brokerage  commissions and fees increased 11% to $4.6 billion  reflecting growth
from business combination  activity,  organic growth and increased new business.
Collectively, the Insurance Brokerage and Other Services and Consulting segments
had organic revenue growth of 6% in 1999 compared to 1998.

Premiums  and other  revenue  of $1.9  billion  increased  9% in 1999  primarily
reflecting  continued growth related to both appliance and electronics  warranty
products and growth from accident and health products.

Investment income of $577 million decreased 2% for the year. The primary factors
contributing  to this decrease were a reduction in  short-term  interest  rates,
mostly outside of the U.S., and lower levels of revenue from equity  securities.
Partially  offsetting the investment income decline was income from the disposal
of tax-exempt bonds (with proceeds reinvested in foreign source income bonds for
tax planning  purposes)  and higher  levels of income from  disposals of private
equity investments. During 1999, investments in limited partnerships and private
equities  increased,  but  still  represented  less  than  10%  of  the  overall
investment portfolio at year-end 1999.

EXPENSES
General expenses,  excluding the 1999 special charges,  increased 10% over prior
year primarily due to additional expenses associated with the integration of new
businesses in 1999, as well as expenses  related to new  initiatives,  increased
levels  of  technology  spending  and a  branding  campaign.  General  expenses,
including special charges, increased 17% reflecting the inclusion of 1999 pretax
special charges of $313 million.

Benefits to  policyholders  increased 9% when compared to 1998,  consistent with
growth  in  related  premiums  earned.   Claims  activity  continued  to  follow
predictable patterns.

Interest  expense  and  amortization  of  intangibles  increased  21%  and  17%,
respectively, largely as a result of acquisitions.

INCOME BEFORE INCOME TAX
Pretax income,  excluding  special  charges,  grew 2% or $17 million,  primarily
reflecting  costs  to  integrate  Aon's  global  network,  increased  technology
expenses and the  launching of a branding  campaign.  Income  before  income tax
decreased  $296 million or 32% in 1999 primarily due to the inclusion of special
charges in 1999.  Approximately  30% of 1999 income before income tax is derived
from non-U.S. operations.

OPERATING SEGMENTS
Aon classifies its businesses into three operating segments: Insurance Brokerage
and Other Services, Consulting and Insurance Underwriting (see note 15).

Aon's operating  segments are identified as those that report separate financial
information  and that are  evaluated  on a  regular  basis  in  deciding  how to
allocate  resources  and  assess  performance.  Total  revenue  for  each of the
operating  segments  is  presented  both by major  product  and  service  and by
geographic  area in note 15. Since Aon's culture fosters  interdependence  among
its operating  units,  the allocation of expenses by product and on a geographic
basis is  difficult  to  delineate.  While  revenue  is  tracked  and  evaluated
separately by management, expenses are allocated to products and services within
each of the  operating  segments.  In addition to revenue,  Aon also  measures a
segment's financial performance using its income before income tax. Revenues are
attributed to geographic areas based on the location of the resources  producing
the revenues.

Operating  segment revenue includes  investment  income related to that segment.
Investment  characteristics  mirror liability  characteristics of the respective
operating segments.  Aon's insurance brokerage and other services and consulting
businesses   invest   fiduciary   funds  and  operating  funds  in  shorter-term
obligations.  Income  derived from these  investments,  as well as the impact of
related  derivatives,  is  included  in the  revenues  of those  businesses.  In
insurance  underwriting,   investments  underlying   interest-sensitive  capital
accumulation  insurance  liabilities are fixed- or floating-rate  fixed-maturity
obligations.  Policyholder  claims  and other  types of  non-interest  sensitive
insurance  liabilities  are  primarily  supported by  intermediate  to long-term
fixed-maturity  instruments.  For the Insurance Underwriting segment,  operating
invested assets are equivalent to average net policy liabilities.

For purposes of the following operating segment discussions, comparisons of 2000
against 1999 results and 1999 against 1998 results exclude special charges.

The following tables and commentary  provide selected  financial  information on
the operating segments.

INSURANCE BROKERAGE AND OTHER SERVICES
The Insurance Brokerage and Other Services segment consists principally of Aon's
retail  brokerage,  reinsurance,  wholesale  and  specialty  brokerage and other
related  services  such as  managing  underwriting  and claims  services.  Aon's
reinsurance  brokerage  activities offer  reinsurance,  analytical  services and
alternative risk financing vehicles. Aon also actively participates in placement
and captive management  services.  Based on revenues,  Aon is the second largest
retail broker and the largest reinsurance broker globally.

The wholesale operations provide brokering expertise and underwriting  solutions
and  custom-designed  products  and  services in several  specialties  including
entertainment,  public entities,  professional liability, workers' compensation,
media and financial institutions.  Some of the services provided in this segment
arise in certain  specialties such as marine,  aviation,  directors and officers
liability, financial institutions, construction and energy.

Approximately  59% of Aon's total  revenues  are  generated  from this  segment.
Revenues are generated  primarily through fees paid by clients;  commissions and
fees  paid  by  insurance  and  reinsurance  companies;  certain  other  carrier
compensation;  and  interest  income  on funds  held  primarily  in a  fiduciary
capacity.  As the broker or intermediary,  Aon is exposed to little underwriting
risk or catastrophic  losses.  Revenues vary from

                                     - 20 -
<PAGE>

quarter  to  quarter  throughout  the year as a result  of the  timing of policy
renewals,  the net effect of new and lost business and the realization of income
on investments. Generally, expenses tend to be more uniform throughout the year.

Revenues  generated by the Insurance  Brokerage and Other  Services  segment are
affected by premium rate levels in the property and casualty  insurance  markets
and available  insurance capacity because  compensation is frequently related to
the premiums paid by insureds.

The highly specialized product  development,  consulting and administrative risk
management  needs  of  professional  groups,  service  businesses,  governments,
healthcare providers and commercial organizations are addressed in this segment.
Affinity  products  for  professional  liability,  life,  disability  income and
personal  lines are  provided  for  individuals,  associations  and  businesses.
Certain operating  subsidiaries provide marketing and brokerage services to both
the primary and reinsurance sectors.

INSURANCE BROKERAGE AND OTHER SERVICES RESULTS FOR 2000 COMPARED TO 1999
REVENUE
Revenue growth,  on a comparable  currency basis, was 9% compared to prior year.
Total 2000 insurance  brokerage and other services revenue was $4.4 billion,  up
5% on a reported  basis.  Organic  growth,  acquisitions,  new  business and the
impact of diminishing  premium rate declines  accounted for the majority of this
revenue growth.  Insurance brokerage and other services operating revenue, on an
organic  basis,  grew  approximately  8%  in  a  very  competitive  environment.
Investment  income  increased $27 million in 2000 as  improvements in short-term
interest  rates and increases in net cash flows  provided from  operations  were
experienced.

On a global  basis  for 2000 and for the first  time in a number  of years,  the
impact of insurance  premium  pricing was neutral and even slightly  positive in
fourth  quarter  2000.  The  property  and  casualty  insurance  market  is very
competitive.  As premium  rates rise,  some  additional  risk may be retained by
clients.  This may limit future  revenue  growth thus  affecting the earnings of
Aon's  brokerage  operations.  In general,  price  firming  outside the U.S. and
London has not been as significant.  In London and the U.S.,  insurance  pricing
levels rose in the second half of 2000.

Insurance  brokerage and other services revenue by geographic  region and pretax
income follows:

U.S. revenue of $2.3 billion rose 6% in 2000 due to increased new business,
acquisitions, the reduced impact of premium rate declines and growth in U.S.
specialty operations. U.K. and Continent of Europe revenues of $1.5 billion
increased 2% from 1999 on the strength of internal growth and, to a lesser
extent, acquisitions. Rest of World revenue increased $59 million or 12% in
2000 primarily reflecting new initiatives and organic growth.

INCOME BEFORE INCOME TAX
Pretax income grew 12% in 2000 compared to 1999 and was  positively  impacted by
strong organic  growth,  particularly  in the retail,  specialty and reinsurance
sectors as well as by the easing of the competitive  premium pricing environment
previously  discussed.  While  this  negatively  affected  income  from  revenue
sharing, poor underwriting  performance  contributed to continued price firming.
Pretax  income  margins in this segment  expanded in 2000 to 17.5% from 16.5% in
1999. Several major factors contributed to the improvement in pretax margins: an
increase  in the  retention  of  existing  business;  higher  investment  income
(reflecting  an increase  in  short-term  interest  rates);  improved  operating
results,  and  more  efficient  cost  management.   Partially  offsetting  these
improvements  were higher  technology costs related to the rollout of Aon's U.S.
retail brokerage policy  management and accounting system and investments in new
initiatives,  with little or no immediate  associated  revenue growth.  Unicover
revenue, which benefited  incrementally Aon's 1999 margin results, was absent in
2000.

CONSULTING
The global  operations  within the  Consulting  segment  provide a full range of
services  related  to  management  of  human  capital,   benefits  and  business
processes.  These services are delivered to a predominantly  corporate clientele
utilizing four practice  groups:  employee  benefits,  compensation,  management
consulting  and  employment  practices   outsourcing.   This  segment  generates
approximately 10% of Aon's consolidated  revenues.  Aon Consulting is one of the
world's largest integrated human resources consulting organizations.

Around the world, employee benefits markets continue to change as companies look
for better ways to manage their human capital costs while  expanding the choices
offered to their employees.  Consulting services include benefit plan design and
administration;  compensation  consulting  and surveys;  employee  selection and
assessment; process improvement; leadership development;  performance management
tools; workforce productivity and individual and organization change management.
Benefits  issues  outside the U.S. are becoming more  complicated  and increased
demand for services in these markets is anticipated.

Revenue in the Consulting segment is affected by changes in clients'  industries
including government regulation, as well as new products and services, the state
of the economic cycle, broad trends in employee  demographics and the management
of large organizations.

CONSULTING RESULTS FOR 2000 COMPARED TO 1999
REVENUE
On a comparable  currency  basis,  consulting  revenue grew 19% during the year.
Revenue grew 11% in 2000 on an organic basis. Reported revenue in 2000 increased
17% to $770 million. On a global basis, revenue growth was influenced by organic
growth,   continued   client  demand  for  solutions   that  enhance   workforce
productivity  and  acquisition  activity.  The ASA  acquisition was completed in
early  October  2000 and its  inclusion  in  fourth  quarter  operating  results
influenced comparisons.

Consulting revenue by geographic area and pretax income follows:

U.S.  revenue  of $486  million in 2000 was up 20% from 1999  reflecting  growth
across  practice  areas and the  acquisition  of ASA.  Strong growth in employee
benefit  services,  partially  offset  by the  sale  of the  financial  planning
consulting business in the U.K., led to the U.K.'s 3% increase in revenue growth
from 1999.  Continent of Europe revenue increased 52% or $23 million  reflecting
growth of existing  businesses and transfers of certain Insurance  Brokerage and
Other Services segment  operating  activities to the Consulting  segment.  These
operations  were  transferred to properly place those  operations in the area of
expertise  where  acceleration  of growth  can best be  achieved.  Rest of World
revenue  increased 10% primarily  attributable  to growth from core  businesses.
Unfavorable foreign exchange rates partially offset overall revenue growth.

INCOME BEFORE INCOME TAX
Total  consulting  pretax  income  increased  $29 million or 36% from prior year
principally  reflecting the inclusion of the ASA acquisition and organic growth.
Pretax margins improved to 14.2% from 12.2% in 1999.

INSURANCE UNDERWRITING
The Insurance  Underwriting segment provides life, accident and health insurance
coverage  through  distribution  networks,  most of which are directly  owned by
Aon's subsidiaries,  and extended warranty and casualty insurance products. This
segment has operations in the United States,  Canada, Latin America,  Europe and
Asia/Pacific and generates approximately 29% of Aon's consolidated revenues.

In the life,  accident  and health  operations,  a sales force of  approximately
8,000  career  agents  call on clients  every six months to  initiate  and renew
coverage and to sell additional  coverage.  The current product  portfolio often
allows   policyholders   the  option  of  paying  premiums   monthly  through  a
pre-authorized  check  mechanism in the U.S. and on a direct

                                     - 22 -
<PAGE>

debit  option  in the U.K.  A wide  range  of  accident-only  and  sickness-only
insurance  products,  including  short-term  disability,  cancer  aid,  Medicare
supplement,  disability income and long-term care coverage are offered.  Most of
the products are primarily fixed-indemnity  obligations,  thereby not subject to
escalating  medical  costs.  In addition to the  traditional  business,  product
distribution has been expanded through payroll deduction and worksite  marketing
programs.

Subsidiaries in North America,  Latin America,  Asia/Pacific  and Europe provide
mechanical  and  appliance  and  electronics  extended  warranty  products.  The
administration of certain extended warranty products on automobiles,  electronic
goods, personal computers and appliances is handled by certain operations in the
Insurance Brokerage and Other Services segment.

INSURANCE UNDERWRITING RESULTS FOR 2000 COMPARED TO 1999
REVENUE
Revenue growth in 2000 was 5% on a comparable  currency basis.  Revenue was $2.2
billion in 2000, up 3% from 1999 on a reported basis.  There was a higher volume
of new business in the U.S. for the mechanical  extended  warranty  products and
worldwide for the appliance and electronics extended warranty products. Accident
and health volumes continued to expand as product  distribution through worksite
marketing programs and the development of new product initiatives, introduced in
1999, grew globally. Revenue growth is predominantly from existing operations as
these   new   initiatives   continue   to  build   momentum.   The   intentional
discontinuation  of one major warranty  renewal that did not meet  profitability
hurdles  and the loss of  revenue  from the  exit of a major  retailer  from the
appliance and  electronics  line partially  offset the otherwise  strong revenue
growth  in  this  segment.  Organically,  insurance  underwriting  revenue  grew
approximately 6% in 2000.

U.S.  revenue of $1.5 billion was up 6% in 2000, as life,  accident  and  health
products  and  extended  warranty  products  all  experienced  growth.  U.K. and
Continent of  Europe  revenue  of  $419  million  declined  10%  reflecting  the
migration  of certain business to fee-based servicing in the Insurance Brokerage
and Other  Services  segment  in first quarter 2000. Rest of World revenue  rose
10% reflecting  continuing  demand  for  the  insurance  warranty  products  and
services.

INCOME BEFORE INCOME TAX
Pretax  income  was  $303  million  in 2000,  up 4% from  last  year.  Partially
impacting  2000  comparisons  was the  positive  runoff of  specialty  liability
policies.  This is the final year that underwriting  earnings are expected to be
impacted by the runoff of those  policies.  Revenue growth and improved  expense
management  were partially  offset by start-up costs related to new accident and
health product  initiatives  and  investments in new product  development in the
extended warranty product lines. These efforts resulted in pretax margins of 14%
for this segment in 2000 compared to 13.8% in 1999. Overall, benefit and expense
margins in 2000 did not suggest any significant shift in operating trends.

Corporate and Other segment revenue consists primarily  of valuation  changes of
investments  in limited  partnerships  and income from certain other investments
(which include  non-income  producing  equities); and income and losses on

                                     - 23 -
<PAGE>

disposals of all securities,  including those pertaining to assets maintained by
the operating segments.

Private  equities  are  principally  carried at cost and usually are  non-income
producing until a disposal occurs. Limited partnerships are accounted for on the
equity method and changes in the value of the underlying partnership investments
impact  corporate  revenue.  Given  the  nature  of  Aon's  limited  partnership
investments,  the reported  income  varies with the market  values of underlying
publicly-traded  equity  investments.   Limited  partnership   investments  have
historically  provided  higher  returns  over a longer time  horizon  than broad
market  common  stock  returns.  However,  in the short  run,  the  returns  are
inherently more variable.

Based on investment  reports received through early 2001, Aon does not expect to
reflect a positive  change in the  valuation  of limited  partnerships  or their
related investment results for first quarter 2001. See "Investment  Operations."
Aon has no influence over the timing of these events. Consequently,  such income
is not predictable and there can be no assurance that Aon will realize levels of
revenue  in  the  future  comparable  to  the  past.  Aon  disposed  of  certain
directly-held  equity  investments  in 1999 and  reinvested  the  proceeds  into
limited  partnerships.  Limited partnership  investments grew to $602 million in
2000 from $465 million in 1999.

CORPORATE AND OTHER RESULTS FOR 2000 COMPARED TO 1999
REVENUE
Corporate  and Other  segment  revenue  decreased  57%  or  $93  million in 2000
compared to 1999.  The  primary factor  contributing  to this decline was a  $78
million  decrease in income on  disposals  of  securities.  In  1999,  there was
approximately  $30  million  of  income on disposals from tax-exempt bonds  plus
income on disposals of other equities, with no significant comparable amounts in
2000.

LOSS BEFORE INCOME TAX
Corporate  operating  expenses include  administrative  and certain  information
technology costs in addition to interest expense and goodwill amortization.  The
pretax loss increased $136 million over 1999. Contributing to the higher loss in
2000 was lower equity related revenue as discussed above. In addition,  interest
expense  increased $35 million or 33%. Higher average  short-term debt levels in
the U.S.  (partly to  finance  acquisitions),  coupled  with  higher  short-term
interest rates,  contributed to approximately 50% of the variance from 1999. The
remaining  interest expense variance reflects the issuance of approximately $500
million of notes since June 1999.  Goodwill  amortization  increased 12% in 2000
reflecting acquisitions.

DISCONTINUED OPERATIONS
Discontinued   operations  are  composed  of  certain   insurance   underwriting
subsidiaries acquired with Alexander and Alexander Services, Inc. (A&A) that are
currently  in  runoff  and the  indemnification  by A&A of  certain  liabilities
relating  to  subsidiaries  sold by A&A prior to Aon's  acquisition.  Management
believes that, based on current  estimates,  these  discontinued  operations are
adequately  reserved.  The  liability  is  included  as  a  component  of  other
liabilities on the consolidated statements of financial position.

INCOME TAXES
The  effective  tax rate was 39%,  38.3%  and  37.5%  for  2000,  1999 and 1998,
respectively.  The  increase  in the  2000  effective  tax  rate  was  primarily
attributable  to a shift in  business  mix. A program  designed to enable Aon to
fully utilize  foreign tax credits by switching from tax-exempt to taxable bonds
contributed  to the 1999  increase.  The overall  effective tax rates are higher
than the U.S.  federal  statutory  rate  primarily  because of state  income tax
provisions and the non-deductibility of certain goodwill.

NET INCOME
Net income for 2000 was $474 million or $1.79 per share compared to $352 million
or $1.33 per share in 1999.  The increase in 2000 net income and the related per
share amount is influenced  primarily by a lower level of 2000 after-tax special
charges of $50  million  ($0.19 per share)  compared to 1999  after-tax  special
charges of $195 million ($0.74 per share).  Partially offsetting the increase in
2000 net income was the adoption of the  Securities  and  Exchange  Commission's
Staff  Accounting  Bulletin  (SAB) 101 (see note 1  "Accounting  and  Disclosure
Changes") which resulted in a one-time  cumulative  noncash charge of $7 million
after-tax ($0.03 per share).  As required by this new accounting  guidance,  Aon
restated the first quarter 2000 results for the cumulative effect of a change in
accounting principle.  The adoption of SAB 101 did not impact the remaining 2000
reported quarterly results.

Net income for fourth  quarter  2000  amounted to $90 million  ($0.33 per share)
compared to $13 million  ($0.05 per share) for 1999.  Basic net income per share
was $1.81 and $1.35 in 2000 and 1999, respectively.  Dividends on the redeemable
preferred  stock in 2000 and 1999 have been  deducted from net income to compute
income per share.

                                     - 24 -
<PAGE>

Net income  excluding  special charges and the cumulative  effect of a change in
accounting  principle  was $531  million or $2.01 per share in 2000  compared to
$547  million  or $2.07  per share in 1999.  The  decrease  in 2000 net  income,
excluding special charges and the accounting change, is primarily  influenced by
a decrease of $93 million  ($57  million  after-tax  or $0.23 per share) in 2000
corporate  and  other  revenue  which  reflected  less  income on  disposals  of
securities.  In fourth  quarter 2000,  dilutive  average  shares  increased 2.1%
primarily due to the issuance of common shares, largely for the ASA acquisition,
and to a lesser  extent,  for  employee  stock  compensation  plans.  Net income
excluding  special charges amounted to $140 million or $0.52 per share in fourth
quarter 2000 compared to $106 million or $0.40 per share for 1999.

Net income for 1999 was $352 million or $1.33 per share compared to $541 million
or $2.07 per share in 1998.  Net income for fourth  quarter 1999 amounted to $13
million or $0.05 per share compared to $139 million or $0.53 per share for 1998.
The decrease in 1999 net income and the related per share  amount is  influenced
primarily by 1999  after-tax  special  charges of $195 million ($0.74 per share)
with no comparable amount in 1998. Net income excluding special charges was $547
million or $2.07 per share in 1999  compared to $541  million or $2.07 per share
in 1998.  Basic  net  income  per  share  was  $1.35 and $2.11 in 1999 and 1998,
respectively.  Dividends on the redeemable preferred stock in 1999 and 1998 have
been deducted from net income to compute income per share.

FINANCIAL CONDITION AND LIQUIDITY
Aon's routine  liquidity  needs are primarily for servicing its debt and for the
payment of dividends on stock issued and the capital securities.  Dividends from
Aon's subsidiaries are the primary source for meeting these requirements.  After
meeting its routine dividend and debt servicing requirements, Aon used a portion
of the remaining  subsidiary dividends received throughout the year to invest in
acquisitions  to expand its  operating  segment  businesses.  There are  certain
regulatory   restrictions   relating  to  dividend  capacity  of  the  insurance
subsidiaries  that are discussed in note 10. Insurance  subsidiaries'  statutory
capital and surplus at year-end 2000 exceeded the risk-based  capital target set
by the National Association of Insurance  Commissioners by a satisfactory level.
Aon's operating subsidiaries anticipate that there will be adequate liquidity to
meet their needs in the  foreseeable  future and to provide  funds to the parent
company.

Aon anticipates that with the continued  positive cash flow of its subsidiaries,
a  fixed-maturity  portfolio  average  life of 5.6 years and access to  adequate
short-term  lines of  credit,  it will  have  sufficient  cash flow to meet both
short-term and long-term cash needs including current dividend  payments.  Given
these factors, Aon anticipates a sufficient level of future operating cash flows
to offset cash payments  related to both  restructuring  charges and  transition
costs associated with the  implementation  of the business  transformation  plan
that commenced in fourth quarter 2000 and will continue through the end of 2001.
Given this immediate need for available cash flows,  Aon  anticipates  deferring
any material  reduction  of debt levels until after the business  transformation
plan is substantially implemented.

OPERATING CASH FLOWS
Aon  has  reclassified  certain  amounts  in  the  "Cash  Flows  from  Operating
Activities"  section of the consolidated  statements of cash flows for the years
ended December 31, 1999 and 1998 to conform to the 2000 presentation.

Cash flows from  operations  generated  $739 million in 2000  compared with $462
million in 1999, an increase of $277 million. Operating cash flows represent the
net income  earned by Aon in those years  adjusted  for noncash  charges such as
amortization of goodwill and other intangibles and depreciation on fixed assets.
Cash was used in the amount of $123  million and $153  million in 2000 and 1999,
respectively,   for  payments  on  special   charges  and  purchase   accounting
liabilities established prior to 2000. In 2000, cash of $16 million was expended
for the business transformation plan.

Net income includes $66 million and $134 million in 2000 and 1999, respectively,
relating to income on disposals,  which is included in investing cash flows, and
noncash income from the limited partnership  portfolio.  Other cash uses of $143
million and $231 million in 2000 and 1999, respectively, primarily relate to net
changes in receivables and payables, as well as the timing of payouts on general
expenses and other liabilities.

INVESTING CASH FLOWS
Investing activities used cash of $137 million in 2000, which was made available
from  operating  activities.  Cash  used  for  various  brokerage  acquisitions,
primarily in Europe,  was $85 million.  Property and equipment and other capital
expenditures for 2000 were $179 million, net of proceeds of $74 million from the
sale of certain  assets.  These  expenditures  primarily  relate to  information
technology and leasehold improvements.

FINANCING CASH FLOWS
Financing  activities during 2000 used cash of $313 million. The primary factors
influencing  the use of cash  were  net  withdrawals  of  $219  million  tied to
scheduled  maturities  on deposits  which are now  substantially  complete,  the
reduction  of  exposure  to

                                     - 25 -
<PAGE>

short-term  funding  agreements  related to capital  accumulation  products  and
dividends of $226  million  offset by the issuance of $250 million of notes (see
note 7). In  addition,  Aon  repurchased  treasury  shares in the  amount of $59
million and $66 million in 2000 and 1999,  respectively,  primarily for employee
benefit plans. Various regulatory requirements applied to Aon's underwriting and
overseas  operations  limit  availability  of  operating  cash flows for general
corporate purposes.

FINANCIAL CONDITION
Total  assets  increased  $1.2 billion  since  year-end  1999 to $22.3  billion.
Invested  assets at December 31, 2000  decreased $165 million from year-end 1999
levels  primarily  resulting  from the  settlement  of other  policyholder  fund
liabilities.  Insurance  brokerage and  consulting  receivables  increased  $722
million in 2000 with a corresponding  increase in insurance premiums payable. In
addition,  general  expense  liabilities  were  reduced  reflecting  paydowns of
special charge liabilities from prior years.

Aon's  consolidated  statement  of  financial  position as of December  31, 2000
contains  a  general  expense  liability  of $89  million  related  to  purchase
restructuring  liabilities  (see note 3) and $44 million related to the business
transformation  plan (see note 4). Aon anticipates  that most of the outstanding
termination  benefits will be settled in 2001 with the remainder to be paid over
the next several years. The remaining items primarily  reflect lease obligations
and will run off over a period  up to 15  years.  Aon does not  anticipate  that
payments for  termination  benefits and lease  obligations  will have a material
impact on cash flows in subsequent periods. Restructuring liabilities related to
recent acquisitions and prior year special charges have been reduced by payments
as planned.

CAPITAL RESOURCES
SHORT-TERM BORROWINGS AND NOTES PAYABLE
At December 31, 2000, Aon had $1.2 billion of back-up lines of credit  available
to support Aon's outstanding  commercial paper that was $874 million at December
31, 2000. In order to achieve tax-efficient financing, Aon established,  in June
1998, a committed  revolving bank credit  facility under which certain  European
subsidiaries can borrow up to EUR 400 million.  As of December 31, 2000, Aon had
borrowed  EUR 279  million  ($260  million)  under this  facility,  of which $35
million is classified as short-term borrowings and $225 million is classified as
notes payable in the consolidated statements of financial position.

Notes  payable  increased by $187 million when  compared to year-end  1999.  The
principal factor  influencing the notes payable increase is the issuance of $250
million of 8.65% notes due May 2005 (see note 7). The net proceeds from the sale
of the 8.65%  notes were used during 2000 for  general  corporate  purposes  and
acquisition  financing.  Debt  repayments and the impact of foreign  exchange on
outstanding  loans under the European bank credit facility  partially offset the
increase in notes payable.

Aon  borrows  funds  from and lends  funds to its  various  subsidiaries.  As of
December 31, 2000, Aon had obligations to its subsidiaries of approximately $550
million. These obligations have competitive interest rates.

STOCKHOLDERS' EQUITY
At December 31, 2000, common stockholders' equity per share increased to $13.02,
up from $11.91 in 1999. The principal factors influencing this increase were net
income and net unrealized investment gains of $49 million. Additionally,  common
stock and paid-in-capital  increased $186 million in 2000, of which $145 million
reflects the ASA and Horizon Group acquisitions financed through the issuance of
common stock.  Partially  offsetting  this  increase  were net foreign  exchange
losses of $115 million and dividends to stockholders of $226 million. Unrealized
investment and foreign exchange  fluctuations  from period to period are largely
based on market  conditions.  Aon believes it is not  economical  to hedge these
short-term noncash fluctuations.

INVESTMENT OPERATIONS
Aon invests in broad asset  categories  related to its  diversified  operations.
Investments  are  managed  with  the  objective  of  maximizing  earnings  while
monitoring  asset  and  liability  durations,  interest  and  credit  risks  and
regulatory requirements. Aon maintains well-capitalized operating companies. The
financial strength of these companies permits a diversified investment portfolio
including invested cash, fixed-income  obligations,  public and private equities
and limited partnerships.

Invested assets and related  investment  income not directly required to support
the insurance brokerage and consulting  businesses,  together with the assets in
excess  of net  policyholder  liabilities  of the  underwriting  businesses  and
related  income,  are  allocated  to the  Corporate  and  Other  segment.  These
diversified assets, which are publicly-traded  equities,  as well as less liquid
private  equities  and  limited   partnerships,   represent  a  more  aggressive
investment  strategy that  provides an  opportunity  for greater  returns with a
longer-term   investment   horizon.   These  assets,   owned  in  the  insurance
underwriting companies, are necessary to support strong claims paying ratings by
independent  rating  agencies  and are  unavailable  for other uses such as debt
reduction or share repurchases without consideration of regulatory  requirements
(see note 10).

                                     - 26 -
<PAGE>

Many of the limited  partnerships in which Aon invests have significant holdings
in  publicly-traded  equities.  Changes in market value of these  equities  flow
through the valuation of the limited partnerships. Aon's ownership share of this
partnership  valuation is included in Aon's reported Corporate and Other segment
revenue.  By  comparison,   changes  in  the  market  value  of  directly  held,
publicly-traded  equities are recorded  directly in stockholders'  equity.  As a
consequence of this accounting, the Corporate and Other segment exhibits greater
variability in investment income than is the case of investments  supporting the
operating segments.

With a  carrying  value of $2.3  billion  at  December  31,  2000,  Aon's  total
fixed-maturity  portfolio is invested  primarily in  investment  grade  holdings
(95%)  and has a fair  value  which  is 98% of  amortized  cost.  Aon's  general
investment  philosophy is to hold  fixed-rate  assets for long-term  investment.
Thus,  it does  not  have a  trading  portfolio.  Aon has  determined  that  its
portfolio of bonds,  notes and  redeemable  preferred  stocks is available to be
sold in response to changes in market  interest  rates,  relative value of asset
sectors,  individual  securities  prepayment and credit risks and Aon's need for
liquidity.

MARKET RISK EXPOSURE
Aon is subject to various market risk exposures  including foreign exchange rate
risk,  interest  rate risk and equity  price  risk.  The  following  disclosures
reflect estimates of future performance and economic conditions.  Actual results
may differ.

Aon is  subject  to  foreign  exchange  rate risk  associated  with  translating
financial   statements   of  its  foreign   subsidiaries   into  U.S.   dollars.
Additionally,  certain of Aon's foreign brokerage  subsidiaries receive revenues
in  currencies  that  differ from their  functional  currencies.  Aon's  primary
exposures  are  associated  with the British  Pound,  the Canadian  Dollar,  the
Australian  Dollar and other European  currencies.  Aon uses various  derivative
financial  instruments (see note 13) to protect against adverse  transaction and
translation effects due to exchange rate fluctuations. The potential decrease to
Aon 's consolidated  stockholders'  equity at December 31, 2000 resulting from a
hypothetical  10% adverse change in quoted year-end  foreign  currency  exchange
rates amounts to $136 million at December 31, 2000 and 1999.  The impact to 2000
and 1999 pretax income in the event of a hypothetical  10% adverse change in the
respective   quoted  year-end   exchange  rates  would  not  be  material  after
consideration of derivative positions.

Due to the  nature  of Aon's  businesses,  income  is  affected  by  changes  in
international  and  domestic  short-term  interest  rates.  Aon  hedges  its net
exposure  to  short-term  interest  rates  with  various  derivative   financial
instruments.  A  hypothetical  1%  decrease  in  interest  rates  would  cause a
decrease, net of derivative positions, of $11 million and $8 million to 2000 and
1999 pretax income, respectively.

The  valuation of Aon's  fixed-maturity  portfolio  is subject to interest  rate
risk. A hypothetical 1% increase in long-term  interest rates would decrease the
fair value of the portfolio at December 31, 2000 and 1999 by approximately  $103
million and $121  million,  respectively.  Aon has  long-term  notes payable and
capital  securities  outstanding  with a fair  value  of $2.6  billion  and $2.4
billion at December  31, 2000 and 1999,  respectively.  Such fair value was less
than the carrying  value by $10 million and $18 million at December 31, 2000 and
1999, respectively.  A hypothetical 1% decrease in interest rates would increase
the fair value by approximately 10% at December 31, 2000 and 1999.

The  valuation of Aon's  marketable  equity  securities  portfolio is subject to
equity price risk.  If market prices were to decrease 10%, the fair value of the
equity portfolio would have a corresponding  decrease of $49 million at December
31, 2000  compared to $57 million at December 31, 1999. At December 31, 2000 and
1999, there were no outstanding derivatives hedging the price risk on the equity
portfolio.


                                     - 27 -
<PAGE>

The  selection of the ranges of values  chosen to  represent  changes in foreign
currency  exchange rates,  equity market prices and interest rates should not be
construed  as  Aon's   prediction  of  future  market  events,   but  rather  an
illustration of the impact of such events.  The range of changes chosen reflects
Aon's view of changes, which are reasonably possible over a one-year period.

The translated value of revenue and expense from Aon's  international  brokerage
and  underwriting  operations  are  subject  to  fluctuations  due to changes in
foreign exchange rates.  However,  the net impact of these fluctuations on Aon's
net income or cash flows has not been material.

In 1999, Aon addressed and  implemented the system  modifications  necessary for
full conversion to the Euro effective  January 1, 2002. The costs related to the
Euro conversion did not have a material  impact on Aon's European  operations in
1999 or 2000.


INFORMATION CONCERNING FORWARD-LOOKING STATEMENTS
This annual report contains certain statements relating to future results, which
are forward-looking statements as that term is defined in the Private Securities
Litigation Reform Act of 1995. These  forward-looking  statements are subject to
certain  risks and  uncertainties  that  could  cause  actual  results to differ
materially from historical results or those anticipated,  depending on a variety
of factors such as general economic conditions in different countries around the
world,  fluctuations  in global  equity  and  fixed-income  markets,  changes in
commercial property and casualty premium rates, the competitive environment, the
actual  cost of  resolution  of  contingent  liabilities,  the final form of the
business transformation plan, the ultimate cost and timing of the implementation
thereof and the actual cost savings and other benefits resulting therefrom.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1 SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES AND PRACTICES
- --------------------------------------------------------------------------------

PRINCIPLES OF CONSOLIDATION
The  accompanying  consolidated  financial  statements  have  been  prepared  in
conformity with accounting  principles  generally  accepted in the United States
and  include the  accounts of Aon  Corporation  and its  operating  subsidiaries
(Aon).  These statements  include informed estimates and assumptions that affect
the amounts reported. Actual results could differ from the amounts reported. All
material intercompany accounts and transactions have been eliminated.

BROKERAGE COMMISSIONS AND FEES
In  general,  commission  income is  recognized  at the later of the  billing or
effective  date of the  related  insurance  policies,  net of an  allowance  for
estimated policy cancellations.  Certain life insurance commissions, commissions
on premiums  billed  directly by insurance  companies  and certain other carrier
compensation  are generally  recognized as income when received.  Commissions on
premium  adjustments  are  recognized as they occur.  Fees for claims  services,
benefit consulting,  reinsurance services and other services are recognized when
the services are rendered.

PREMIUM REVENUE
In general,  for accident and health and extended  warranty  products,  premiums
collected are reported as earned in proportion to insurance  protection provided
over the  period  covered  by the  policies.  For life  products,  premiums  are
recognized as revenue when due.

For  universal  life-type  and  investment  products,   generally  there  is  no
requirement  for payment of premium other than to maintain  account  values at a
level  sufficient to pay mortality and expense charges.  Consequently,  premiums
for universal  life-type  policies and  investment  products are not reported as
revenue,  but as deposits.  Policy fee revenue for universal  life-type policies
and investment  products  consists of charges for the cost of insurance,  policy
administration  and  surrenders  assessed  during the period.  Expenses  include
interest  credited to policy  account  balances and benefit  claims  incurred in
excess of policy account balances.

REINSURANCE
Reinsurance  premiums,  commissions  and  expense  reimbursements  on  reinsured
business are accounted for on a basis  consistent  with those used in accounting
for the original  policies  issued and the terms of the  reinsurance  contracts.
Premiums and benefits ceded to other companies have been reported as a reduction
of premium revenue and benefits.  Expense reimbursements  received in connection
with  reinsurance  ceded have been  accounted  for as a reduction of the related
policy  acquisition  costs or, to the  extent  such  reimbursements  exceed  the
related acquisition costs, as other revenue. Reinsurance receivables and prepaid
reinsurance premium amounts are reported as assets.

STOCK COMPENSATION PLANS
Aon applies  Accounting  Principles  Board Opinion No. 25,  Accounting for Stock
Issued  to  Employees,   and  related  Interpretations  in  accounting  for  its
stock-based  compensation plans.  Accordingly,  no compensation expense has been
recognized  for its  stock  option  plan as the  exercise  price of the  options
equaled the market price of the stock at the date of grant. Compensation expense
has been recognized for stock awards issued pursuant to the Aon Stock Award Plan
based on the market price at the date of the award.

INCOME TAX
Deferred  income tax has been provided for the effects of temporary  differences
between financial reporting and tax bases of assets and liabilities and has been
measured  using the enacted  marginal  tax rates and laws that are  currently in
effect.

INCOME PER SHARE
Basic  income  per share is  computed  based on the  weighted-average  number of
common shares outstanding, excluding any dilutive effects of options and awards.
Net income available for common stockholders is net of all preferred  dividends.
Dilutive  income per share is computed based on the  weighted-average  number of
common shares  outstanding  plus the dilutive effect of options and awards.  The
dilutive  effect of options and awards is  calculated  under the treasury  stock
method  using the  average  market  price for the  period.  Income  per share is
calculated as follows:

INVESTMENTS
Fixed-maturity  securities are available for sale and are carried at fair value.
The amortized cost of fixed  maturities is adjusted for amortization of premiums
to the first call date and the  accretion  of  discounts  to  maturity  that are
included  in  investment  income.  Marketable  equity  securities  that are held
directly are carried at fair value.  Unrealized  gains and temporary  unrealized
losses on fixed maturities and directly-held equity securities are excluded from
income and are recorded  directly to stockholders'  equity in accumulated  other
comprehensive  income or loss,  net of deferred  income taxes.  Mortgage  loans,
policy loans and private  equity  investments  are generally  carried at cost or
unpaid principal balance.

Limited partnership investments are carried under the equity method. Many of the
limited   partnerships  in  which  Aon  invests  have  significant  holdings  in
publicly-traded  equities.  Changes  in  market  value of these  indirectly-held
equities  flow through the limited  partnerships'  statements.  Aon's  ownership
share of these  valuation  changes  is  included  in Aon's  reported  investment
income.

Income or loss on disposal of any  securities  held in the portfolio is computed
using specific costs of securities sold and reported as investment income in the
consolidated statements of income.

Investments  that have declines in fair value below cost, which are judged to be
other than  temporary,  are written down to estimated fair values.  Reserves for
certain  other  investments  are  established  based  on an  evaluation  of  the
respective investment portfolio and current economic conditions.  Writedowns and
changes in  reserves  are  included  in  investment  income in the  consolidated
statements of income.  In general,  Aon ceases to accrue investment income where
interest or dividend payments are in arrears.

Accounting policies relating to derivative  financial  instruments are discussed
in note 13.

DEFERRED POLICY ACQUISITION COSTS
Costs of acquiring new and renewal insurance underwriting business,  principally
the excess of new commissions over renewal  commissions,  underwriting and sales
expenses  that vary with and are  primarily  related  to the  production  of new
business,  are  deferred  and reported as assets.  For long-  duration  life and
health products, amortization of deferred policy acquisition costs is related to
and  based  on the  expected  premium  revenues  of the  policies.  In  general,
amortization  is adjusted to reflect  current  withdrawal  experience.  Expected
premium  revenues are estimated by using the same assumptions used in estimating
future  policy  benefits.   For  extended  warranty  and  short-duration  health
insurance,  costs of acquiring and renewing  business are deferred and amortized
as the related premium is earned.

INTANGIBLE ASSETS
In general,  the excess of cost over net assets  purchased  relating to business
acquisitions  is being amortized into income over periods not exceeding 40 years
using the straight-line  method,  with a weighted-average  life of 35 years. The
cost of other intangible assets is being amortized over a range of 4 to 25 years
with  a  weighted-average  life  of 18  years.

In the unexpected event  of a significant deterioration in profitability that is
expected to be recurring, Aon would assess the  recoverability of its intangible
assets through an analysis of expected future cash flows.

PROPERTY AND EQUIPMENT
Property and  equipment,  reported in other assets,  are  generally  depreciated
using the  straight-line  method over their estimated useful lives.  Included in
this  category is internal  use  software,  which is software  that is acquired,
internally  developed or modified solely to meet internal needs, with no plan to
market externally. Costs related to directly obtaining,  developing or upgrading
internal use software are capitalized. These costs are generally amortized using
the straight-line method over a range of 2 to 8 years. The weighted-average life
of Aon's software at December 31, 2000 is 5.6 years.

FAIR VALUE OF FINANCIAL INSTRUMENTS
The  following  methods and  assumptions  were used to estimate  fair values for
financial  instruments.  The carrying amounts in the consolidated  statements of
financial  position  for  cash  and  cash  equivalents,   including   short-term
investments,  approximate  their fair value. Fair value for  fixed-maturity  and
equity  securities is based on quoted market prices or, if they are not actively
traded,  on estimated values obtained from independent  pricing  services.  Fair
value  of  derivative  financial  instruments  is  based on  quoted  prices  for
exchange-traded  instruments  or the cost to  terminate  or  offset  with  other
contracts.

Other investments are composed of mortgage loans,  policy loans,  private equity
investments  and limited  partnerships.  The fair value for  mortgage  loans and
policy loans is estimated using  discounted  cash flow analyses,  using interest
rates currently being offered for similar loans to borrowers with similar credit
ratings.  It is not  practical  to  estimate  the fair value of  private  equity
investments and limited partnerships without incurring excessive costs.

Fair value for  liabilities  for  investment-type  contracts is estimated  using
discounted  cash flow  calculations  based on  interest  rates  currently  being
offered for similar  contracts with  maturities  consistent with those remaining
for the  contracts  being  valued.  The fair value for notes payable is based on
quoted  market  prices for the  publicly-traded  portion and on estimates  using
discounted cash flow analyses based on current borrowing rates for similar types
of borrowing arrangements for the nonpublicly-traded portion.

FUTURE POLICY BENEFITS,  POLICY AND CONTRACT CLAIMS AND UNEARNED PREMIUMS
Future policy benefit  liabilities on non-universal life and accident and health
products have been provided on the net level premium method. The liabilities are
calculated based on assumptions as to investment yield, mortality, morbidity and
withdrawal  rates  that were  determined  at the date of issue and  provide  for
possible adverse deviations. Interest assumptions are graded and range from 4.5%
to 7.0% at December 31, 2000.  Withdrawal  assumptions are based  principally on
insurance subsidiaries' experience and vary by plan, year of issue and duration.

Policyholder liabilities on universal life and investment products are generally
based on policy account  values.  Interest credit rates for these products range
from 5.2% to 8.1%.

Policy and contract claim liabilities  represent  estimates for reported claims,
as well as provisions  for losses  incurred,  but not yet reported.  These claim
liabilities are based on historical experience and are estimates of the ultimate
amount  to be paid  when  the  claims  are  settled.  Changes  in the  estimated
liability are reflected in income as the estimates are revised.

Unearned  premiums  generally are calculated  using the pro rata method based on
gross premiums. However, in the case of extended warranty products, the unearned
premiums  are  calculated  such that the  premiums are earned over the period of
risk in a reasonable relationship to anticipated claims.

FOREIGN CURRENCY TRANSLATION
In general,  foreign  revenues and expenses are  translated at average  exchange
rates. Foreign assets and liabilities are translated at year-end exchange rates.
Net foreign  exchange gains and losses on translation are generally  reported in
stockholders'  equity, in accumulated other comprehensive income or loss, net of
deferred  income  tax.  The  effect  of  transaction  gains  and  losses  on the
consolidated statements of income is insignificant for all periods presented.

ACCOUNTING AND DISCLOSURE CHANGES
As of October 1, 2000, the Company adopted Financial  Accounting Standards Board
(FASB)  Statement No. 133,  Accounting  for Derivative  Instruments  and Hedging
Activities  (Statement 133), as amended.  The adoption of Statement 133 resulted
in a $5 million  cumulative  effect of a change in accounting  principle  before
applicable  income  taxes of $2 million  and was  recognized  as an  increase to
accumulated other comprehensive income (note 2) in the consolidated statement of
stockholders'  equity for the year ended  December  31,  2000.  The  adoption of
Statement  133 did not have a  material  effect on net income for the year ended
December 31, 2000.  Refer to note 13 for a description  of  accounting  policies
relating to derivative financial instruments.

In December  1999, the  Securities  and Exchange  Commission  (SEC) issued Staff
Accounting  Bulletin  (SAB)  No.  101,  which  provides  guidance  for  applying
generally  accepted  accounting  principles  relating  to the  timing of revenue
recognition in financial  statements  filed with the SEC.  Effective  January 1,
2000, in accordance  with the provisions of SAB 101, Aon established a provision
for  estimated  returned  commissions  from  policy  cancellations.  In 1999 and
previous years,  Aon recognized  returned  commissions  when they occurred.  The
cumulative  effect  of this  accounting  change  was an  after-tax  charge of $7
million  or $0.03 per share in the first  quarter of 2000.  Previously  reported
results for the remaining  quarters of 2000 were not impacted by this accounting
change.  Pro forma results for 1999 and 1998 are not  materially  different from
previously reported results.

In September 2000, the FASB issued Statement No. 140,  Accounting  for Transfers
and Servicing of Financial Assets and  Extinguishments of Liabilities. Statement
No. 140 replaces Statement No. 125 and revises the standards for  accounting for
securitizations  and  other  transfers  of  financial assets and  collateral and
requires certain disclosures.  Statement  No. 140 is effective for all transfers
of financial assets  occurring after March 31, 2001. Aon has not  yet determined
the  effect,  if  any,  this statement will have on the  consolidated  financial
statements.

RECLASSIFICATION
Certain  amounts in prior years'  consolidated  financial  statements  have been
reclassified to conform to the 2000 presentation.

3 BUSINESS COMBINATIONS
- --------------------------------------------------------------------------------

ACQUISITIONS
PURCHASE METHOD
In 2000, Aon acquired Actuarial Sciences Associates,  Inc., an employee benefits
and compensation  consulting firm, and Horizon  Consulting  Group,  Inc., a firm
specializing in commercial  policyholder claim consulting services,  and certain
other insurance brokerage and consulting operations. In these transactions,  Aon
paid an  aggregate  of  approximately  $85  million in cash and $145  million in
stock.  Internal  funds,  short-term  borrowings  and common stock  financed the
acquisitions.  Excess of cost over net assets  purchased of  approximately  $225
million  accounted for on a preliminary  basis resulted from these  acquisitions
and is primarily being amortized over 40 years.

In 1999,  Aon acquired  The Nikols  Group,  Presidium  Holdings,  Inc.,  Societe
Generale  d'Assurance et de Prevoganie and certain other insurance brokerage and
consulting   operations  for  approximately  $440  million.  Aon  also  acquired
insurance  underwriting  blocks  of  business  for  $50  million.  The  purchase
accounting for these  acquisitions was finalized in 2000. The acquisitions  were
financed by internal funds,  short-term  borrowings and common stock.  Excess of
cost over net assets purchased of approximately $500 million resulted from these
acquisitions and is primarily being amortized over 40 years.

In 1998,  Aon  acquired Le Blanc de Nicolay,  Gil y Carvajal  and certain  other
operations for  approximately  $400 million.  The acquisitions  were financed by
internal  funds  and  short-term  borrowings.  Excess  of cost  over net  assets
purchased of approximately  $400 million resulted from these acquisitions and is
being amortized over 40 years.

The  results  of  operations  from  these   acquisitions  are  included  in  the
consolidated  financial statements from the dates they were acquired.  Pro forma
results from these  acquisitions  are not  materially  different  from  reported
results.

In accordance  with a 1992 purchase  agreement,  securities  with a value of $43
million  are being  held  pursuant  to an escrow  agreement  (as  amended).  The
escrowed securities will be released on a predetermined schedule through 2007.

POOLING OF INTERESTS METHOD
In 1998,  Aon  issued  2.3  million  shares of common  stock  for  mergers  with
insurance brokerage and consulting  organizations.  Aon's prior period financial
statements  have not been  restated  for the  mergers  because the effect of the
mergers was not material.

RESTRUCTURING CHARGES
In 1999, Aon consummated a plan of  restructuring  its operations as a result of
business  combination  activity.  A charge  was  recorded  in the amount of $120
million. Total termination benefits were $67 million and related pension expense
was $32 million,  involving 900 positions, of which 860 terminations occurred in
1999 and 40 occurred in 2000.  Benefits related to pension plans are included in
Aon's total pension liability.  Workforce reductions were related to a voluntary
early  retirement  plan for  employees  of Aon's  U.S.  and  Canadian  operating
subsidiaries, as well as the consolidation of Aon's European insurance brokerage
and other services  operations,  primarily in the United Kingdom.  The remaining
charges of $21  million  primarily  reflect  lease  abandonments  of $11 million
relating  to the  consolidation  of  worldwide  brokerage  operations  and asset
impairments of $10 million.

The  following  table  demonstrates  the activity  related to the  liability for
termination benefits and abandoned leases:

The combination of 1998 acquisitions and the finalization of purchase accounting
for the 1997 Jauch & Hubener  acquisition  resulted  in $70  million of purchase
accounting  liabilities  consisting  primarily of termination benefits and lease
abandonments. Termination of 160 positions occurred in 1998 and 1999 as planned.

In 1997,  Aon  recorded  pretax  special  charges  of $145  million  related  to
management's  commitment  to a  formal  plan of  restructuring  Aon's  brokerage
operations  as a result of the  acquisition  of Alexander & Alexander  Services,
Inc.  (A&A).  These  charges,  in  addition  to certain  charges  taken in 1996,
constitute the "Aon Plan." The  restructuring  charges included costs related to
termination benefits of $40 million,  lease abandonments and other exit costs of
$68 million,  and asset impairments of $37 million related to the abandonment of
systems and real estate space.  Terminations  of 600 positions  occurred in 1997
and 1998 as planned.  Lease abandonments of $54 million are primarily located in
the United Kingdom and are being paid out over several years as planned.

The  following  table   demonstrates  the  activity  related  to  the  Aon  Plan
liabilities:

Also  in  1997,   following   management's   commitment  to  a  formal  plan  of
restructuring the A&A and Bain Hogg brokerage operations, Aon estimated costs of
$264 million which were  allocated to the cost of those  acquisitions  (the "A&A
and Bain Hogg Plan").  The costs  primarily  relate to termination  benefits and
lease abandonments. Terminations of 2,000 positions occurred in 1997 and 1998 as
planned.

The remaining liabilities at December 31, 2000 primarily relate to real estate.

general  expense  liabilities  in  the  consolidated   statements  of  financial
position.

4 BUSINESS TRANSFORMATION PLAN
- --------------------------------------------------------------------------------

In fourth  quarter  2000,  Aon recorded  pretax  special  charges of $82 million
related to the Board's approval in principle of, and management's commitment to,
a formal plan of restructuring Aon's worldwide operations. This plan constitutes
the "business  transformation  plan" to be implemented during the fourth quarter
of 2000 and  throughout  2001.  Costs of the plan  include  special  charges and
transition  costs. The special charges in the fourth quarter 2000 included costs
related to termination benefits of $54 million,  other costs to exit an activity
of $6 million and asset  impairments and other charges of $22 million  primarily
relating  to the  abandonment  of systems  and  equipment.  The  elimination  of
approximately  500  positions  occurred in the fourth  quarter,  the majority of
which were related to the Insurance  Brokerage and Other Services segment in the
U.S. and the U.K.

The  following  table  demonstrates  the activity  related to the  liability for
termination benefits and costs to exit an activity:

5 DISCONTINUED OPERATIONS
- --------------------------------------------------------------------------------

A&A discontinued its property and casualty insurance underwriting  operations in
1985,  some of which were then placed into runoff,  with the  remainder  sold in
1987. In connection with those sales, A&A provided  indemnities to the purchaser
for various estimated and potential  liabilities,  including provisions to cover
future  losses  attributable  to  insurance  pooling  arrangements,  a stop-loss
reinsurance  agreement and actions or omissions by various underwriting agencies
previously managed by an A&A subsidiary.

As  of  December  31,  2000,  the  liabilities  associated  with  the  foregoing
indemnities  and  liabilities of insurance  underwriting  subsidiaries  that are
currently in runoff result principally from asbestos, pollution and other health
hazard  insurance  claims  and  were  included  in  other   liabilities  in  the
consolidated statements of financial position. Such liabilities amounted to $136
million,  net of reinsurance  recoverables and other assets of $175 million, and
would be  substantially  reduced if a  February  2000  ruling  from the Court of
Appeal in England favorable to A&A, in respect of which right to appeal has been
granted, were upheld in a decision expected in or around 2002.

The  insurance  liabilities  represent  estimates  of known  and  future  claims
expected to be made under  occurrence-based  insurance  policies and reinsurance
business.  Those  claims are expected to develop and be settled over the next 20
to 30 years.

The  insurance  liabilities  cannot be estimated  using  conventional  actuarial
reserving  techniques  because  of,  among  other  matters,  the  inadequacy  of
available historical  experience to support such techniques and because case law
and  scientific  standards for measuring the adequacy of site clean-up are still
evolving.  Therefore,  independent  actuaries have combined  available  exposure
information with other relevant  industry data and have used various  projection
techniques to estimate the insurance liabilities.

Although these insurance  liabilities  represent a best estimate of the probable
liabilities,  adverse developments may occur given the nature of the information
available  and the  variables  inherent in the  estimation  processes.  Based on
current  estimates,  management  believes that the  established  liabilities  of
discontinued operations are sufficient.

Securities on deposit for regulatory  authorities as required by law amounted to
$311 million at December  31, 2000 and $323  million at December  31,  1999.  As
required  by the by-laws of Lloyd's  brokers,  cash and  short-term  investments
subject to floating charges for the benefit of insurance  creditors  amounted to
$1.0 billion and $1.2 billion at December 31, 2000 and 1999,  respectively.  Aon
maintained  premium trust bank accounts for premiums collected from insureds but
not yet remitted to insurance companies of $1.3 billion at December 31, 2000 and
1999.

At  December  31,  2000  and  1999,   Aon  had  $66  million  and  $41  million,
respectively, of non-income producing investments.

Total notes payable                                $ 1,798     $ 1,611
- -----------------------------------------------------------------------

Commercial  paper  borrowings of $600 million at December 31, 2000 and 1999 have
been  included in notes payable based on Aon's intent and ability to maintain or
refinance these  obligations on a long-term basis through 2002.

In May 1999, Aon filed a universal  shelf  registration on Form S-3 with the SEC
for the issuance of $500 million of debt and equity securities. In a 1999 public
offering based on the shelf  registration,  Aon issued $250 million of 6.9% debt
securities due July 2004.  The net proceeds from the sale of the 6.9% notes were
used to reduce outstanding short-term commercial paper borrowings.

In May 2000, Aon filed a prospectus supplement to use the remaining $250 million
of its  universal  shelf  registration  and  issued  $250  million of 8.65% debt
securities  due May 2005. The net proceeds from the sale of the 8.65% notes were
used for general corporate purposes,  including securities  repurchase programs,
capital expenditures,  working capital,  repayment or reduction of long-term and
short-term debt and the financing of acquisitions.

Interest is payable semi-annually on all debt securities.  In addition, the debt
securities  are not  redeemable  by Aon prior to maturity and contain no sinking
fund provisions. Maturities of notes payable are $12 million, $704 million, $377
million,  $433  million and $250  million in 2001,  2002,  2003,  2004 and 2005,
respectively.

In 1998, Aon entered into a committed  bank credit  facility under which certain
European  subsidiaries  can borrow up to EUR 400 million.  At December 31, 2000,
Aon had borrowed EUR 279 million ($260 million)  under this  facility,  of which
$35  million  is  classified  as  short-term  borrowings  and  $225  million  is
classified  as  notes  payable  in  the  consolidated  statements  of  financial
position.  Aon has $1.2 billion of other unused committed bank credit facilities
at  December  31, 2000 to support  $874  million of  commercial  paper and other
short-term  borrowings  of  which  $274  million  is  classified  as  short-term
borrowings at December 31, 2000.

Information  related  to notes  payable  (excluding  the debt  guarantee  of the
Employee Stock Ownership Plan (ESOP)) and short-term borrowings is as follows:

DEBT GUARANTEE OF ESOP
Aon's ESOP entered into loan agreements to purchase Aon common stock.  The loans
were  unconditionally  guaranteed by Aon and therefore the unpaid balance of the
loans  was  classified  as  notes  payable  in  the  accompanying   consolidated
statements of financial position.  An equivalent amount,  representing  deferred
compensation,  was recorded as a deduction from  stockholders'  equity. The ESOP
paid  $18  million  in 1999  and  1998,  in loan  principal  and  interest  from
contributions  made by Aon to the ESOP,  as well as dividend  proceeds of common
stock held by the ESOP.  The loans had an interest  rate of 8.35% and matured in
1999. The remaining 1.1 million shares were released for allocation in 1999.

LEASE COMMITMENTS
Aon  has  noncancelable operating leases for certain office space, equipment and
automobiles. Future minimum rental payments required under operating leases that
have  initial or remaining  noncancelable  lease terms in excess  of one year at

*Before cumulative effect of change in accounting  principle.

During 2000, 1999 and 1998,  Aon's  consolidated  statements of income reflect a
tax benefit of $26 million,  $26  million  and $25 million, respectively, on the
8.205%  capital securities issued in January 1997 (see note 10).

A  reconciliation  of the  income  tax  provisions  based on the U.S.  statutory
corporate tax rate to the  provisions  reflected in the  consolidated  financial
statements is as follows:

There are  limitations  on the  utilization of net operating loss and tax credit
carryforwards  after a change of  control,  consequently,  there  will be annual
limitations  on the  realization  of these tax  assets.  Accordingly,  valuation
allowances were established for various acquisitions.  Subsequently,  recognized
tax  benefits  for these  items  would  reduce  excess  of cost over net  assets
purchased.   Although  future  earnings  cannot  be  predicted  with  certainty,
management  currently  believes that  realization of the net deferred tax assets
after consideration of the valuation allowance is more likely than not.

Prior to 1984, the life insurance companies were required to accumulate  certain
untaxed amounts in a memorandum "policyholders' surplus account."  Under the Tax
Reform Act of 1984, the "policyholders' surplus account" balances were  "capped"
at  December 31, 1983,  and the  balances  will  be  taxed only  to  the  extent
distributed to stockholders or when they exceed certain prescribed limits. As of
December 31, 2000, the combined  "policyholders'  surplus account" of Aon's life
insurance  subsidiaries  approximates   $363  million.    Aon's  life  insurance
subsidiaries  do  not  intend  to make any  taxable distributions or exceed  the
prescribed limits in the foreseeable future; therefore, no income tax  provision
has been made. However, if such taxes were assessed, the amount of taxes payable
would be approximately $127 million.

The amount of income taxes paid in 2000,  1999 and 1998 was $158  million,  $324
million and $249 million, respectively.


9 REINSURANCE AND CLAIM RESERVES
- --------------------------------------------------------------------------------

Aon's insurance  subsidiaries are involved in both the cession and assumption of
reinsurance  with other  companies.  Aon's  reinsurance  consists  primarily  of
short-duration   contracts  that  are  entered  into  with  numerous  automobile
dealerships  and insurers.  Aon's  insurance  subsidiaries  remain liable to the
extent that the reinsuring companies are unable to meet their obligations.

A summary of reinsurance activity is as follows:

10 REDEEMABLE PREFERRED STOCK, CAPITAL SECURITIES AND STOCKHOLDERS' EQUITY
- ------------------------------------------------------------------------------

REDEEMABLE PREFERRED STOCK
At  December  31,  2000,  1 million  shares of  redeemable  preferred  stock are
outstanding.  Dividends are cumulative at an annual rate of $2.55 per share. The
shares of redeemable  preferred stock will be redeemable at the option of Aon or
the holders,  in whole or in part, at $50.00 per share  beginning one year after
the occurrence of certain future events.

CAPITAL SECURITIES
In January 1997,  Aon created Aon Capital A, a wholly-owned  statutory  business
trust,  for the  purpose of issuing  mandatorily  redeemable  preferred  capital
securities  (Capital  Securities).  The sole  asset of Aon  Capital A is an $824
million  aggregate   principal  amount  of  Aon's  8.205%  Junior   Subordinated
Deferrable Interest  Debentures due January 1, 2027. The back-up guarantees,  in
the  aggregate,  provide  a full  and  unconditional  guarantee  of the  Trust's
obligations under the Capital Securities.

Aon Capital A issued $800 million of 8.205% capital  securities in January 1997.
The proceeds from the issuance of the Capital  Securities were used to finance a
portion of the A&A acquisition.  The Capital Securities are subject to mandatory
redemption on January 1, 2027 or, are  redeemable in whole,  but not in part, at
the option of Aon upon the  occurrence  of certain  events.  Interest is payable
semi-annually on the Capital Securities.  The Capital Securities are categorized
in the  consolidated  statements  of  financial  position as  "Company-Obligated
Mandatorily  Redeemable Preferred Capital Securities of Subsidiary Trust Holding
Solely the Company's Junior  Subordinated  Debentures."  The after-tax  interest
incurred on the  Capital  Securities  is  reported  as minority  interest in the
consolidated statements of income.


COMMON STOCK
In 2000,  Aon's  stockholders  approved an  amendment  to Aon's  Certificate  of
Incorporation  to increase the number of authorized  shares of common stock from
300 million to 750 million.

Aon repurchased 3.5 million,  2.8 million and 1 million shares in 2000, 1999 and
1998,  respectively,  of its common stock, primarily to provide shares for stock
compensation  plans.  In  addition,  Aon issued 5.3 million new shares of common
stock in 2000 for employee benefit plans and for acquisitions.

DIVIDENDS
A summary of dividends incurred is as follows:

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


STATUTORY CAPITAL AND SURPLUS
Generally, the capital and surplus of Aon's insurance subsidiaries available for
transfer to the parent  company are  limited to the amounts  that the  insurance
subsidiaries'  statutory  capital and surplus exceed minimum  statutory  capital
requirements;  however,  payments of the amounts as dividends  may be subject to
approval  by  regulatory  authorities.  See note 8 for  possible  tax effects of
distributions made out of untaxed earnings.

Net statutory income of the insurance subsidiaries is summarized as follows:

The National  Association  of  Insurance  Commissioners  revised the  Accounting
Practices and Procedures  Manual in a process referred to as  Codification.  The
revised  manual is effective  January 1, 2001. The  domiciliary  states of Aon's
major insurance  subsidiaries have adopted the provisions of the revised manual.
The revised manual has changed, to some extent,  prescribed statutory accounting
practices  and will  result in changes to the  accounting  practices  that Aon's
major  insurance  subsidiaries  use to prepare their  statutory-basis  financial
statements.  The impact of these changes to Aon's major insurance  subsidiaries'
statutory  capital  and  surplus  as of January  1, 2001 is not  expected  to be
significant.

11 EMPLOYEE BENEFITS
- --------------------------------------------------------------------------------

SAVINGS AND PROFIT SHARING PLANS
Aon subsidiaries  maintain  contributory savings plans for the benefit of United
States salaried and commissioned employees. Provisions made for these plans were
$39 million, $37 million and $22 million in 2000, 1999 and 1998, respectively.

EMPLOYEE STOCK OWNERSHIP PLAN
Aon  subsidiaries  maintained a leveraged  ESOP for the benefit of United States
salaried and certain  commissioned  employees.  The final  allocation  under the
leveraged ESOP was for 1998.  Contributions  to the ESOP amounted to $16 million
in 1998.

PENSION AND OTHER POSTRETIREMENT BENEFITS
Aon sponsors  defined  benefit,  pension and  postretirement  health and welfare
plans  that  provide  retirement,  medical  and  life  insurance  benefits.  The
postretirement  healthcare plans are  contributory,  with retiree  contributions
adjusted annually; the life insurance and pension plans are noncontributory.

In 2000, plans with a projected  benefit  obligation (PBO) in excess of the fair
value of plan assets were  unfunded  plans with a PBO of $55 million,  and plans
with an accumulated benefit obligation (ABO) in excess of the fair value of plan
assets were unfunded plans with an ABO of $46 million. In 1999, plans with a PBO
in excess of the fair value of plan assets were unfunded plans with a PBO of $41
million,  and plans with an ABO in excess of the fair value of plan  assets were

Pension plan assets  include 3.7 million and 2.5 million  shares of common stock
issued by Aon on which  dividends of $3 million and $2 million were  received in
2000 and 1999, respectively.

In February  1999,  Aon  established a limited time early  retirement  incentive
program that provided  benefits  through the defined  benefit  pension plan. The
additional cost of termination  benefits  applicable for 1999 resulting from the
program has been included in the preceding table.

The  following  table  provides  the  components  of net  periodic  benefit cost
(credit) for the plans for the years ended December 31, 2000, 1999 and 1998:

The weighted-average assumptions for the measurement period for U.S. benefit

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


ASSUMPTIONS FOR OTHER POSTRETIREMENT BENEFITS
The employer's liability for future plan cost increase is limited in any year to
5% per annum.  For measurement  purposes in 2000, 1999 and 1998, the annual rate
of increase in the per capita cost of covered health care benefits  (trend rate)
adjusted for actual current year cost  experience  was assumed to be 7.5%,  7.0%
and 7.5%, respectively,  decreasing gradually to 5.5% in year 2004 and remaining
the same thereafter.  However, with the employer funding increase cap limited to
5% per year, net employer trend rates are effectively  limited to 5% per year in
the future.

As a result, a 1% change in assumed healthcare cost trend rates has no effect on
the  service  and  interest  cost  components  of  net  periodic  postretirement
healthcare benefit cost and on the accumulated postretirement benefit obligation
for the measurement period ended in 2000.

In 2000,  plans with a PBO in excess of the fair value of plan  assets had a PBO
of $1.2  billion and plan assets  with a fair value of $1.1  billion,  and plans
with an ABO in  excess  of the  fair  value  of plan  assets  had an ABO of $434
million and plan assets with a fair value of $399 million.

In 1999, plans with a PBO in excess of the fair  value of plan  assets had a PBO
of $1.4  billion  and plan assets with a fair value of $1.3  billion,  and plans
with  an  ABO  in excess  of  the fair value of plan  assets had an ABO  of $480

12 STOCK COMPENSATION PLANS
- --------------------------------------------------------------------------------

STOCK AWARD PLAN
Under the Aon Stock Award Plan,  Aon could  award up to 19.4  million  shares of
common stock. Generally, the award plan requires the employees to complete three
continuous  years of service before the award begins to vest in increments until
the completion of a ten-year period of continuous  employment.  In general, most
awarded shares are issued as they become vested.  In certain  circumstances,  an
employee can elect to defer the receipt of vested  shares to a later date.  With
certain  limited  exceptions,  any break in  continuous  employment  will  cause
forfeiture of all unvested awards.  The  compensation  cost associated with each
award is deferred and amortized over the period of continuous  employment  using
the  straight-line  method.  In 2000, the plan was amended to add the ability to
grant  options  pursuant to the  provisions  of the Aon Stock  Option  Plan.  At
December 31, 2000,  the number of shares  available  for award is included  with
options available for grant.

Aon common stock awards outstanding consist of the following:

STOCK OPTION PLAN
Under the nonqualified  Aon Stock Option Plan,  options to purchase common stock
were granted to certain  officers and employees of Aon and its  subsidiaries  at
100% of market  value on the date of grant.  Under  the  plan,  Aon could  issue
options to purchase up to 35 million shares. Generally, the option plan requires
employees to complete two  continuous  years of service before the options begin
to vest in increments  until the completion of a four-year  period of continuous
employment.  For all  grants  made  prior to an  amendment  to the plan in 2000,
employees were required to complete three continuous years of service before the
options began to vest in increments until the completion of a six-year period of
continuous employment.

PRO FORMA INFORMATION
Pro forma information  regarding net income and net income per share is required
by FASB  Statement  No. 123 and has been  determined as if Aon had accounted for
employee stock options and stock awards under the fair value method.

The pro forma net income and net income per share information is as follows:

EMPLOYEE STOCK PURCHASE PLANS
UNITED STATES
Effective  July 1, 1998,  Aon  adopted an  employee  stock  purchase  plan which
provides  for the  purchase of a maximum of 7.5 million  shares of Aon's  common
stock by eligible  U.S.  employees.  Under the  original  plan,  shares of Aon's
common stock could be  purchased  at six-month  intervals at 85% of the lower of
the fair market  value of the common  stock on the first or the last day of each
six-month  period.  Effective July 1, 2000, the plan was amended by changing the
purchase period to three-month  intervals.  In 2000 and 1999, 940,000 shares and
720,000 shares, respectively, were issued to employees under the plan. No shares
were issued under the plan in 1998.

UNITED KINGDOM
In 1999,  Aon adopted an employee  stock  purchase  plan which  provides for the
purchase of  approximately  720,000  shares of Aon common stock by eligible U.K.
employees  after a  three-year  period and is broadly  similar to the U.S.  plan
described above. No shares were issued under the plan in either 1999 or 2000.


13 FINANCIAL INSTRUMENTS
- --------------------------------------------------------------------------------

FINANCIAL RISK MANAGEMENT
Aon is exposed to market risk from changes in foreign  currency  exchange rates,
interest rates and equity securities prices. To manage the risk related to these
exposures,  Aon enters into various derivative transactions that have the effect
of reducing these risks by creating offsetting market exposures.  If Aon did not
use derivative contracts, its exposure to market risk would be higher.

Derivative transactions are governed by a uniform set of policies and procedures
covering  areas  such   as  authorization,  counterparty  exposure  and  hedging
practices.  Positions  are  monitored using techniques such as market value  and
sensitivity analyses.

Certain   derivatives   also  give  rise  to  credit  risks  from  the  possible
non-performance by  counterparties.  The credit risk is generally limited to the
fair value of those  contracts  that are  favorable  to Aon. Aon has limited its
credit risk by  restricting  investments  in  derivative  contracts to a diverse
group of highly rated major financial  institutions and by using exchange-traded
instruments. Aon closely monitors the credit-worthiness of, and exposure to, its
counterparties and considers its credit risk to be minimal. At December 31, 2000
and 1999, Aon placed securities relating to these derivative contracts in escrow
amounting to $1 million and $4 million, respectively.

Foreign  currency forward  contracts  (forwards) and interest rate swaps entered
into  require no up-front  premium.  Forwards  settle at the  expiration  of the
related  contract.  The net effect of swap payments is settled  periodically and
reported in income.  The  premium and  commission  paid for  purchased  options,
including interest rate caps and floors, and premium received, net of commission
paid,  for written  options  represent  the cost basis of the position  until it
expires or is closed.  The commission paid for futures contracts  represents the
cost  basis of the  position  until it  expires  or is  closed.  Exchange-traded
futures  are  valued and  settled  daily.  Unless  otherwise  noted,  derivative
instruments are generally  reported in other  receivables and liabilities in the
consolidated statements of financial position.

ACCOUNTING POLICY FOR DERIVATIVE FINANCIAL INSTRUMENTS
Effective October 1, 2000, Aon adopted Statement 133 (see note 1). Statement 133
requires  all  derivative  instruments  to be  recognized  in  the  consolidated
statements  of  financial  position  at fair  value.  Changes  in fair value are
recognized  immediately  in earnings  unless the  derivative  is designated as a
hedge and qualifies for hedge accounting.

Statement 133 identifies three hedging relationships where a derivative (hedging
instrument)  may  qualify  for hedge  accounting:  a hedge of the change in fair
value of a recognized  asset or liability or firm commitment (fair value hedge),
a hedge of the variability in cash flows from a recognized asset or liability or
forecasted  transaction (cash flow hedge) and a hedge of the net investment in a
foreign subsidiary.

In order for a derivative to qualify for hedge  accounting,  the derivative must
be formally  documented and designated as a hedge at inception and be consistent
with Aon's overall risk management policy. The hedge relationship must be highly
effective at inception and on an ongoing basis.  For a highly  effective  hedge,
changes  in the  fair  value  of the  hedging  instrument  must be  expected  to
substantially  offset changes in the fair value of the hedged item. Aon performs
frequent analyses to measure hedge effectiveness.

The change in fair value of a hedging  instrument  designated and qualified as a
fair value hedge and the change in value of

                                     - 50 -
<PAGE>

the  hedged  item  attributable  to the risk being  hedged  are both  recognized
currently in earnings.  The  effective  portion of the change in fair value of a
hedging  instrument  designated and qualified as a cash flow hedge is recognized
in other comprehensive income (OCI) and subsequently reclassified to income when
the hedged item affects earnings.  The ineffective portion of the change in fair
value  of a cash  flow  hedge  is  recognized  immediately  in  earnings.  For a
derivative  designated and qualified as a hedge of a net investment in a foreign
subsidiary, the effective portion of the change in fair value is reported in OCI
as part of the cumulative translation adjustment. The ineffective portion of the
change in fair value of a hedge of a net  investment in a foreign  subsidiary is
recognized immediately in earnings.

Prior to the adoption of Statement 133, the ineffective portion of the change in
fair value of a hedging  instrument  designated and qualified as a hedge was not
recognized immediately in earnings.

FOREIGN EXCHANGE RISK MANAGEMENT
Certain of Aon's foreign brokerage subsidiaries,  primarily in the U.K., receive
revenues in currencies that differ from their functional  currencies.  To reduce
the  variability  of cash flows from these  transactions,  Aon has entered  into
foreign exchange  forwards and options with settlement dates prior to July 2003.
Upon adoption of Statement 133,  designated and qualified forwards are accounted
for as cash flow  hedges of  forecasted  transactions.  Since  the  adoption  of
Statement  133, a $4 million pretax gain has been deferred to OCI, $3 million of
which is  expected  to impact  earnings  in 2001.  There was no  ineffectiveness
recorded.

Prior to the adoption of Statement 133, these  transactions  did not qualify for
hedge accounting and changes in the fair value related to these derivatives were
recorded in general expenses in the consolidated  statements of income.  Certain
other  forward and option  contracts  did not meet the hedging  requirements  of
Statement 133. Changes in fair value related to these contracts were recorded in
general expenses in the consolidated statements of income.

Aon uses  exchange-traded  foreign currency  futures and options on futures,  as
well as  over-the-counter  options and forward contracts to reduce the impact of
foreign currency  fluctuations on the translation of the financial statements of
Aon's foreign operations. These derivatives are not afforded hedge accounting as
defined by  Statement  133 and prior  accounting  guidance.  Changes in the fair
value of these  derivatives are recorded in general expenses in the consolidated
statements of income.

In 2000,  Aon entered into a cross  currency swap to hedge the foreign  currency
and  interest  rate  risks  associated  with a  foreign  denominated  fixed-rate
policyholder  liability.  This swap has been designated as a fair value hedge of
the combined  exposure.  There was no material  ineffectiveness  related to this
hedge.

INTEREST RATE RISK MANAGEMENT
Aon sells futures contracts and purchases options on futures contracts to reduce
the price volatility of its fixed-maturity portfolio. Upon adoption of Statement
133,  derivatives  designated  and  qualified as hedging  specific  fixed-income
securities  are accounted for as fair value hedges.  There are no designated and
qualified  hedges at December 31, 2000.  Prior to the adoption of Statement 133,
realized gains and losses on derivatives  that qualified as hedges were deferred
and reported as an adjustment of the cost basis of the hedged item and are being
amortized into earnings over the remaining life of the hedged item.  Outstanding
derivatives hedging  fixed-maturities at December 31, 1999 were recorded at fair
value with changes in the derivative fair value reported as unrealized gains and
losses in OCI.

Prior to the adoption of Statement 133, Aon purchased futures contracts to hedge
the fair value of its  fixed-rate  notes from  changes in  interest  rates.  Aon
deferred the gains from the termination of the contracts and is amortizing these
gains over the remaining life of the fixed-rate notes.

Aon issued  fixed-rate notes in May 2000. Aon purchased options on interest rate
swaps to hedge against the change in interest rates prior to the issuance. These
options  qualified  as  a  hedge  of  an  anticipated  transaction  under  prior
accounting  guidance and related gains were deferred and are being  amortized as
an offset to interest  expense over the  remaining  life of the notes.  Upon the
adoption of Statement 133, pretax deferred gains of $5 million were reclassified
to OCI. At December 31, 2000, this amount remains in OCI, $1 million of which is
expected to offset interest expense in 2001.

Aon  enters  into  interest  rate  swap  and  floor   agreements  and  purchases
exchange-traded  futures  and  options  to  limit  its  exposure  to  decreasing
short-term  interest rates,  primarily relating to brokerage  fiduciary funds in
the U.S. and U.K.  Since the adoption of Statement 133, there were no designated
and  qualified  cash  flow  hedges  of this  exposure.  Under  prior  accounting
guidance,  unrealized  gains and losses were not  recorded  in the  consolidated
statements of financial position and realized gains and losses were deferred and
recognized in earnings as the hedged item affected earnings.

                                     - 51 -
<PAGE>

Aon uses  interest  rate  swaps and caps to limit its  exposure  to  changes  in
interest rates related to interest rate  guarantees  provided by a subsidiary of
Aon to certain unaffiliated  entities.  Under prior accounting  guidance,  these
derivatives  qualified  for hedge  accounting  treatment.  Unrealized  gains and
losses were not recorded in the consolidated statements of financial position as
of December 31, 1999 and realized  gains and losses were deferred and recognized
in  earnings  as the  hedged  item  affected  earnings.  In August  2000,  these
guarantees were replaced with new offsetting interest rate swaps between Aon and
an  unaffiliated  entity,  with Aon  essentially  retaining  the same  exposure.
Following the  replacement  of the original  hedged item,  hedge  accounting was
terminated  and  previously  deferred  realized  gains  and  losses  as  well as
previously  unrecognized  changes  in fair value were  recognized  currently  in
earnings.  The termination of this hedging  relationship did not have a material
effect on pretax  earnings.  The  adoption of  Statement  133 did not affect the
accounting for these derivative instruments.

EQUITY PRICE RISK MANAGEMENT
Aon sells futures contracts and purchases options to reduce the price volatility
of its equity  securities  portfolio and equity  securities  it owns  indirectly
through limited  partnership  investments.  Since the adoption of Statement 133,
there were no designated  and qualified  hedges of this  exposure.  Prior to the
adoption  of  Statement  133,  realized  gains and  losses on  derivatives  that
qualified  as hedges were  deferred and  reported as an  adjustment  of the cost
basis  of the  hedged  item  and are  being  amortized  into  earnings  over the
remaining  life of the  hedged  item.  Outstanding  derivatives  hedging  equity
securities  at December 31, 1999 were recorded at fair value with changes in the
derivative fair value reported as unrealized  gains and losses in OCI.  Realized
gains and  losses  on  derivatives  that did not  qualify  for hedge  accounting
treatment were  recognized  currently in investment  income in the  consolidated
statements of income.

OTHER FINANCIAL INSTRUMENTS
Aon has certain investment  commitments to provide capital and fixed-rate loans,
as well  as  certain  forward  contract  purchase  commitments.  The  investment
commitments,  which  would  be  collateralized  by  related  properties  of  the
underlying  investments,  involve  varying  elements of credit and market  risk.
Investment  commitments  outstanding  at December 31, 2000 and 1999 totaled $184
million and $312 million, respectively.

Subsidiaries  and affiliates of Aon have entered into  agreements with financial
institutions,  whereby certain  receivables  were sold,  with limited  recourse.
Agreements  provide  for sales of  receivables  on a  continuing  basis  through
November  2001.  As of  December  31,  2000 and  1999,  the  maximum  commitment
contained in these  agreements was $2.9 billion and $3.6 billion,  respectively.
Aon's maximum  credit risk under  recourse  provisions of these  agreements  was
approximately  $197  million  and $260  million at  December  31, 2000 and 1999,
respectively. In 1999, a subsidiary of Aon sold $10 million of credit protection
in the form of a credit default swap and purchased  similar  credit  protection,
also  in  the  form  of a  credit  default  swap,  to  offset  its  risk  in the
transaction.

An  Aon  subsidiary  issues  fixed-  and  floating-rate   Guaranteed  Investment
Contracts (GICS) and floating-rate  funding  agreements and invests the proceeds
primarily  in the U.S.  fixed-income  markets.  The assets  backing the GICS are
subject to varying elements of credit and market risk.

FAIR VALUE OF FINANCIAL INSTRUMENTS
Accounting standards require the disclosure of fair values for certain financial
instruments.  The fair value  disclosures  are not  intended  to  encompass  the
majority of policy liabilities, various other non-financial instruments or other
intangible  assets  related  to Aon's  business.  Accordingly,  care  should  be
exercised in deriving  conclusions  about Aon's business or financial  condition
based on the fair  value  disclosures.  The  carrying  value  and fair  value of
certain of Aon's financial instruments are as follows:


As of December 31                                  2000              1999

14 CONTINGENCIES
- --------------------------------------------------------------------------------

Aon and its  subsidiaries  are subject to numerous  claims,  tax assessments and
lawsuits that arise in the ordinary course of business.  The damages that may be
claimed are  substantial,  including  in many  instances  claims for punitive or
extraordinary damages. Accruals for these items have been provided to the extent
that losses are deemed probable and are estimable.

In 1998, the Internal  Revenue Service (IRS) proposed  adjustments to the tax of
certain Aon  subsidiaries  for the period of 1990  through  1993.  Most of these
adjustments  should  be  resolved  through  factual  substantiation  of  certain
accounting  matters.  However,  the IRS has contended that retro-rated  extended
warranty  contracts do not constitute  insurance for tax purposes.  Accordingly,
the IRS has  proposed a deferral  of  deductions  for  obligations  under  those
contracts.  The effect of such  deferral  would be to  increase  the current tax
obligations  of certain  Aon  subsidiaries  by  approximately  $74  million,  $3
million,  $5 million and $12 million (plus  interest) in years 1990,  1991, 1992
and 1993,  respectively.  Aon believes that the IRS's  position is without merit
and  inconsistent  with numerous  previous IRS private letter  rulings.  Aon has
commenced  an  administrative  appeal and  intends to  contest  vigorously  such
treatment. Aon believes that if the contracts are deemed not to be insurance for
tax  purposes,  they would be  recharacterized  in such a way that the increased
taxes for the years in question would be far less than the proposed assessments.

In the second quarter of 1999,  Allianz Life Insurance Company of North America,
Inc.  ("Allianz")  filed an amended  complaint in  Minnesota  adding a brokerage
subsidiary  of Aon as a defendant in an action  which  Allianz  brought  against
three insurance  carriers  reinsured by Allianz.  These three carriers  provided
certain types of workers' compensation  reinsurance to a pool of insurers and to
certain facilities managed by Unicover Managers, Inc. ("Unicover"), a New Jersey
corporation  not affiliated  with Aon.  Allianz  alleges that the Aon subsidiary
acted as an agent of the three  carriers  when placing  reinsurance  coverage on
their behalf.  Allianz claims that the reinsurance it issued should be rescinded
or that it should be awarded damages, based on alleged fraudulent, negligent and
innocent misrepresentations by the carriers, through their agents, including the
Aon subsidiary  defendant.  Aon believes that the Aon subsidiary has meritorious
defenses and the Aon subsidiary intends to vigorously defend this claim.

Except for an action  filed to compel Aon to produce  documents  to which Aon is
responding,  the Allianz lawsuit is the only lawsuit or arbitration  relating to
Unicover in which any  Aon-related  entity is  currently a party.  In 1999,  Aon
charged  general  expenses for $72 million in the Insurance  Brokerage and Other
Services segment relating to various litigation matters including Unicover.

Certain  United  Kingdom  subsidiaries  of  Aon  have  been  required  by  their
regulatory body, the Personal Investment Authority (PIA), to review advice given
by those  subsidiaries to individuals who bought pension plans during the period
from April 1988 to June 1994.  These reviews have  resulted in a requirement  to
pay compensation to clients based on guidelines  issued by the PIA. In 1999, Aon
charged general  expenses for $121 million in the Consulting  segment to provide
for these  payments.  Aon's  ultimate  exposure  from the private  pension  plan
review,  as  presently  calculated,  is subject to a number of variable  factors
including,  among others,  general level of pricing in the equity  markets,  the
interest  rate  established  quarterly  for  calculating  compensation,  and the
precise scope, duration and methodology of the review,  including whether recent
regulatory guidance will have to be applied to previously settled claims.

Although  the  ultimate  outcome  of all  matters  referred  to above  cannot be
ascertained  and liabilities in  indeterminate  amounts may be imposed on Aon or
its subsidiaries, on the basis of present information, amounts already provided,
availability of insurance coverages and legal advice received, it is the opinion
of management that the disposition or ultimate determination of such claims will
not have a material  adverse effect on the  consolidated  financial  position of
Aon. However, it is possible that future results of operations or cash flows for
any  particular  quarterly or annual period could be  materially  affected by an
unfavorable resolution of these matters.

15 SEGMENT INFORMATION
- --------------------------------------------------------------------------------

Aon classifies its businesses into three operating segments: Insurance Brokerage
and  Other   Services,   Consulting   and  Insurance   Underwriting.   A  fourth
non-operating  segment,  Corporate and Other, when aggregated with the operating
segments,  totals to the  amounts  in the  accompanying  consolidated  financial
statements. Revenues are attributed to geographic areas based on the location of
the  resources  producing  revenues.  Intercompany  revenues  and  expenses  are
eliminated in computing  consolidated  revenues and income before tax. There are
no  material  inter-segment  amounts  to be  eliminated.  Long-lived  assets and
related depreciation and amortization are not material.


Consolidated revenue by geographic area follows:

REPORTS BY INDEPENDENT AUDITORS AND MANAGEMENT

REPORT OF ERNST & YOUNG LLP,
INDEPENDENT AUDITORS


BOARD OF DIRECTORS AND STOCKHOLDERS
AON CORPORATION

We have audited the accompanying  consolidated  statements of financial position
of  Aon  Corporation  as  of  December  31,  2000  and  1999,  and  the  related
consolidated statements of income,  stockholders' equity and cash flows for each
of the three  years in the period  ended  December  31,  2000.  These  financial
statements   are  the   responsibility   of  the   Company's   management.   Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. 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 financial  statements  referred to above present fairly, in
all material respects, the consolidated financial position of Aon Corporation at
December 31, 2000 and 1999, and the  consolidated  results of its operations and
its cash flows for each of the three  years in the  period  ended  December  31,
2000, in conformity with accounting  principles generally accepted in the United
States.

As discussed in Note 1, in 2000,  the Company  changed its method of  accounting
for certain commission and fee revenue and also changed its method of accounting
for derivative financial instruments.

REPORT BY MANAGEMENT

Management  of  Aon Corporation  is responsible for the fairness of presentation
and integrity of the financial statements and other financial information in the
annual report. The financial  statements have been prepared in  conformity  with
accounting principles generally accepted in the United States.  These statements
include informed estimates and judgments for those transactions not yet complete
or  for  which  the  ultimate  effects cannot be measured  precisely.  Financial
information  elsewhere in this report is  consistent with that in the  financial
statements.  The consolidated  financial  statements have  been  audited  by our
independent  auditors.  Their role  is  to render  an  independent  professional
opinion on Aon's financial statements.

Management  maintains  a  system  of  internal  control  designed  to  meet  its
responsibilities  for reliable financial  statements.  The system is designed to
provide reasonable assurance,  at appropriate costs, that assets are safeguarded
and that  transactions  are properly  recorded and executed in  accordance  with
management's  authorization.  Judgments  are  required to assess and balance the
relative  costs and  expected  benefits of those  controls.  It is  management's
opinion  that its  system  of  internal  control  as of  December  31,  2000 was
effective in providing  reasonable  assurance that its financial statements were
free of material misstatement.  In addition, management supports and maintains a
professional  staff of internal  auditors who coordinate audit coverage with the
independent   auditors  and  conduct  an  extensive  program  of  financial  and
operational audits.

The Board of Directors  selects an Audit  Committee from among its members.  All
members  of the  Audit  Committee  are  independent  of the  Company.  The Audit
Committee  recommends to the Board of Directors  appointment of the  independent
auditors and provides oversight relating to the review of financial  information
provided to  stockholders  and others,  the  systems of internal  control  which
management  and the Board of Directors have  established  and the audit process.
The Audit Committee meets  periodically  with management,  internal auditors and
independent  auditors to review the work of each and  satisfy  itself that those
parties are properly  discharging their  responsibilities.  Both the independent
auditors  and the  internal  auditors  have free access to the Audit  Committee,
without the presence of management,  to discuss the adequacy of internal control
and to review the quality of financial reporting.
