Prospectus Supplement
(To Prospectus Dated August 31, 2012)
$350,000,000
4.00% Senior Notes due 2023
With a full and unconditional guarantee as to payment of
principal and interest by Aon Corporation
Aon plc is offering $350,000,000 aggregate principal amount of 4.00% senior notes due 2023 (the "Notes"). The Notes will mature
on November 27, 2023. Aon plc will pay interest on the Notes on each May 27 and November 27, commencing on May 27, 2014. Aon plc
may redeem all of the Notes at any time, and some of the Notes from time to time, at the redemption prices set forth in this prospectus
supplement under "Description of the Securities--Optional Redemption." We may also redeem all of the Notes at a redemption price equal
to 100% of their principal amount plus accrued and unpaid interest, if any, to the redemption date in the event of certain changes in respect
of withholding taxes applicable to the Notes and Guarantee, as described in this prospectus supplement under "Description of the Securities
--Optional Tax Redemption."
The Notes will be fully and unconditionally guaranteed by Aon Corporation, or Aon Delaware (the "Guarantee" and, together with the
Notes, the "Securities").
The Notes will be Aon plc's general unsecured and unsubordinated obligations and will rank equally with each other and with all of
Aon plc's other present and future unsecured and unsubordinated obligations. The Notes will not have the benefit of all of the covenants
applicable to some of Aon plc's existing unsecured senior debt. The Notes will be effectively subordinated to any secured debt Aon plc
may have or incur in the future to the extent of the value of the assets securing such indebtedness. The Notes will be structurally
subordinated to the debt and all other obligations of Aon plc's subsidiaries (though you may have a direct claim as to Aon Delaware by
virtue of its obligations with respect to the Guarantee).
The Guarantee will be a general unsecured and unsubordinated obligation of Aon Delaware and will rank equally with all of Aon
Delaware's other present and future unsecured and unsubordinated obligations. The Guarantee will not have the benefit of all of the
covenants applicable to some of Aon Delaware's existing unsecured senior debt. The Guarantee will be effectively subordinated to any
secured debt Aon Delaware may have or incur in the future to the extent of the value of the assets securing such indebtedness. The
Guarantee will be structurally subordinated to the debt and all other obligations of Aon Delaware's subsidiaries.
We intend to apply to list the Notes on the New York Stock Exchange or another "recognised stock exchange" for purposes of
Section 1005 of the U.K. Income Tax Act 2007.
Investing in the Securities involves a high degree of risk. See "Risk Factors" beginning on page S-11 of
this prospectus supplement.
Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these
Securities or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation
to the contrary is a criminal offense.

DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS
This prospectus supplement, the accompanying prospectus and any documents incorporated by reference into this prospectus
supplement or the accompanying prospectus contain certain statements related to future results, or states our intentions, beliefs and
expectations or predictions for the future which are forward-looking statements as that term is defined in the Private Securities Litigation
Reform Act of 1995. Forward-looking statements relate to expectations or forecasts of future events. They use words such as "anticipate,"
"believe," "estimate," "expect," "forecast," "project," "intend," "plan," "potential," and other similar terms, and future or conditional tense
verbs like "could," "may," "might," "should," "will" and "would." You can also identify forward-looking statements by the fact that they do
not relate strictly to historical or current facts. For example, we may use forward-looking statements when addressing topics such as:
market and industry conditions, including competitive and pricing trends; changes in our business strategies and methods of generating
revenue; the development and performance of our services and products; changes in the composition or level of our revenues; our cost
structure and the outcome of cost-saving or restructuring initiatives; the outcome of contingencies; dividend policy; the expected impact of
acquisitions and dispositions; pension obligations; cash flow and liquidity; future actions by regulators; and the impact of changes in
accounting rules. These forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ
materially from either historical or anticipated results depending on a variety of factors. Potential factors that could impact results include:
·
general economic conditions in different countries in which we do business around the world, including conditions in the
European Union relating to sovereign debt and the continued viability of the Euro;
·
changes in the competitive environment;
·
changes in global equity and fixed income markets that could influence the return on invested assets;
·
changes in the funding status of our various defined benefit pension plans and the impact of any increased pension funding
resulting from those changes;
·
rating agency actions that could affect our ability to borrow funds;
·
fluctuations in exchange and interest rates that could impact revenue and expense;
·
the impact of class actions and individual lawsuits including client class actions, securities class actions, derivative actions
and ERISA class actions;
·
the impact of any investigations brought by regulatory authorities in the United States (the "U.S."), the United Kingdom (the
"U.K.") and other countries;
·
the cost of resolution of other contingent liabilities and loss contingencies, including potential liabilities arising from errors
and omission claims against us;
·
failure to retain and attract qualified personnel;
·
the impact of, and potential challenges in complying with, legislation and regulation in the jurisdictions in which we
operate, particularly given the global scope of our business and the possibility of conflicting regulatory requirements across
jurisdictions in which we do business;
·
the effect of the Redomestication on our operations and financial results, including the reaction of our clients, employees and
other constituents, the effect of compliance with applicable U.K. regulatory regimes or the failure to realize some or all of
the anticipated benefits;
·
the extent to which we retain existing clients and attract new businesses and our ability to incentivize and retain key
employees;

·
the extent to which we manage certain risks created in connection with the various services, including fiduciary and
advisory services, among others, that we currently provide, or will provide in the future, to clients;
·
the possibility that the expected efficiencies and cost savings from the acquisition of Hewitt will not be realized, or will not
be realized within the expected time period;
·
the risk that the Hewitt businesses will not be integrated successfully;
·
our ability to implement restructuring initiatives and other initiatives intended to yield cost savings, and the ability to
achieve those cost savings;
·
the potential of a system or network disruption resulting in operational interruption or improper disclosure of personal data;
·
any inquiries relating to compliance with the U.S. Foreign Corrupt Practices Act and non-U.S. anti-corruption laws and with
U.S. and non-U.S. trade sanctions regimes; and
·
our ability to grow and develop companies that we acquire or new lines of business.
Any or all of these forward-looking statements may turn out to be inaccurate, and there are no guarantees about our performance. The
factors identified above are not exhaustive. We and our subsidiaries operate in a dynamic business environment in which new risks emerge
frequently. Accordingly, you should not place undue reliance on forward-looking statements, which speak only as of the dates on which they
are made. We are under no obligation (and expressly disclaim any obligation) to update or alter any forward-looking statement that we may
make from time to time, whether as a result of new information, future events or otherwise. Further information about factors that could
materially affect Aon, including our results of operations and financial condition, is contained in the "Risk Factors" section in Part I,
Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2012 as filed with the SEC.
