NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

1.Statement of Accounting Principles

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and include all normal recurring adjustments which Aon Corporation (“Aon” or the “Company”) considers necessary to present fairly the Company’s consolidated financial statements for all periods presented.

Certain information and footnote disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted.  These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2008.  The results for the three and six months ended June 30, 2009 are not necessarily indicative of operating results that may be expected for the full year ending December 31, 2009.  Certain amounts in prior period financial statements and related notes have been reclassified to conform to the 2009 presentation.  In addition, due to the adoption of new principles regarding noncontrolling interests and participating securities, certain amounts in prior period financial statements and related notes have been restated to conform with the requirements of these new principles.

The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of reserves and expenses during the reporting periods.  Actual amounts could differ from those estimates.

Management has reviewed all material subsequent events through August 7, 2009, the date the financial statements were issued, to determine whether any event required either recognition or disclosure in the financial statements.

2.Accounting Principles and Practices

Changes in Accounting Principles

On January 1, 2009, Aon adopted revised principles related to business combinations and noncontrolling interests.  The revised principle on business combinations applies to all transactions or other events in which an entity obtains control over one or more businesses.  It requires an acquirer to recognize the assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree at the acquisition date, measured at their fair values as of that date.  Business combinations achieved in stages require recognition of the identifiable assets and liabilities, as well as the noncontrolling interest in the acquiree, at the full amounts of their fair values when control is obtained.  This revision also changes the requirements for recognizing assets acquired and liabilities assumed arising from contingencies, and requires direct acquisition costs to be expensed.  In addition, it provides certain changes to income tax accounting for business combinations which apply to both new and previously existing business combinations.  In April 2009, additional guidance was issued which revised certain business combination guidance related to accounting for contingent liabilities assumed in a business combination. The Company has adopted this guidance in conjunction with the adoption of the revised principles related to business combinations. The adoption of the revised principles related to business combinations has not had a material impact on the consolidated financial statements.

The revised principle related to noncontrolling interests establishes accounting and reporting standards for the noncontrolling interests in a subsidiary and for the deconsolidation of a subsidiary.  The revised

6

principle clarifies that a noncontrolling interest in a subsidiary is an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements.  The revised principle also requires reported consolidated net income to include the amounts attributable to both the parent and the noncontrolling interest. The revised principle requires retrospective adjustments, for all periods presented, of stockholders’ equity and net income for noncontrolling interests.  In addition to these financial reporting changes, the revised principle provides for significant changes in accounting related to noncontrolling interests; specifically, increases and decreases in Aon’s controlling financial interests in consolidated subsidiaries will be reported in equity similar to treasury stock transactions.  If a change in ownership of a consolidated subsidiary results in loss of control and deconsolidation, any retained ownership interests are remeasured with the gain or loss reported in net income. In previous periods, noncontrolling interests for operating subsidiaries were reported in other general expenses in the condensed consolidated statements of income.  Prior period amounts have been restated to conform to the current year’s presentation.

On January 1, 2009, Aon also adopted a new principle which supplements current disclosure requirements for derivative instruments and hedging activities, under which Aon is required to provide enhanced qualitative and quantitative information.  See Note 13 for these disclosures.

Effective January 1, 2009, the Company also adopted additional guidance which states that unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents are participating securities, as defined, and therefore should be included in computing earnings per share using the two class method.  Certain of Aon’s restricted stock awards allow the holder to receive a non-forfeitable dividend equivalent.  All prior periods earnings per share data have been adjusted to conform to the current presentation.  See Note 4 for further discussion of the effect of adopting this new guidance on the Company’s financial statements.

Effective April 1, 2009, Aon adopted a new principle which establishes the period after the balance sheet date during which management is required to evaluate events or transactions that may occur for potential recognition or disclosure in the financial statements.  This principle also requires that Aon disclose the date through which subsequent events have been evaluated, as well as whether that date is the date the financial statements were issued or the date the financial statements were available to be issued.  See Note 1 for this disclosure.

Aon also adopted the following effective April 1, 2009:

·additional guidance for estimating fair value in accordance with current principles, when the volume and level of activity for the asset or liability has significantly decreased.  This guidance also assists in identifying circumstances that indicate when a transaction is not orderly.

·guidance related to debt securities, which requires an entity to recognize the credit component of an other-than-temporary impairment of a debt security in earnings and the non-credit component in other comprehensive income when the entity does not intend to sell the security and it is more likely than not that the entity will not be required to sell the security prior to recovery.  Entities are required to record a cumulative effect adjustment for the non-credit component of previously recognized other-than-temporary impairments that meet certain criteria.

·disclosure guidance related to the fair value of financial instruments for interim reporting periods as well as in annual financial statements.

7

The adoption of the preceding guidance did not have a material impact on the Company’s financial statements.  See Note 16 for the disclosure regarding interim reporting of the carrying and fair value of Aon’s long-term debt.

Recent Accounting Pronouncements

In December 2008, the Financial Accounting Standards Board (“FASB”) issued an amendment to current principles regarding employers’ disclosures about pensions and other postretirement benefits.  These changes provide guidance as to an employer’s disclosures about plan assets of a defined benefit pension or other postretirement plan.  This amendment requires pension and other postretirement plan disclosures be expanded to include investment allocation decisions, the fair value of each major category of plan assets based on the nature and risks of assets in the plans, and inputs and valuation techniques used to develop fair value measurements of plan assets.  The Company is currently evaluating this amendment to determine any additional disclosures required in the 2009 annual report.

In June 2009, the FASB issued guidance amending current principles related to the transfers of financial assets and variable interest entities (“VIEs”).  This guidance eliminates the concept of a qualifying special-purpose entity (“QSPE”), creates more stringent conditions for reporting the transfer of a portion of a financial asset as a sale, clarifies other sale-accounting criteria, and changes the initial measurement of a transferor’s interest in transferred financial assets.  Former QSPEs will be evaluated for consolidation based on the updated VIE guidance.  There are also changes to the approach a company must take in determining a VIE’s primary beneficiary and requires companies to more frequently reassess whether they must consolidate VIEs.  Additional year-end and interim period disclosures will also be required.  These changes will be effective for Aon beginning in the first quarter of 2010.  The Company is currently evaluating this guidance to determine what impact, if any, it will have in its consolidated financial statements.

3.Cash and Cash Equivalents

Cash and cash equivalents at June 30, 2009 and December 31, 2008 included restricted balances of $117 million and $194 million, respectively.  Restricted balances are held in trust for the benefit of reinsurance contract holders.

6.Disposal of Operations

Continuing Operations

In December 2008, Aon signed a definitive agreement to sell the U.S. operation of the premium finance business of Cananwill, Inc. (“Cananwill”).  This disposition was completed in February 2009. Cananwill’s results are included in the Risk and Insurance Brokerage Services segment.  A pretax loss totaling $7 million was recorded, of which $2 million was recorded in first quarter 2009 and $5 million in 2008.  This disposal did not meet the criteria for discontinued operations reporting.  Aon may receive up to $10 million from the buyer over the next two years based on the volume of insurance premiums and related obligations financed by the buyer over this period that are generated by certain of Cananwill’s producers.

Discontinued Operations

Property and Casualty Operations

In January 2009, the Company signed a definitive agreement to sell FFG Insurance Company (“FFG”), Atlanta International Insurance Company (“AIIC”) and Citadel Insurance Company (“Citadel”) (together the “P&C operations”).  FFG and Citadel are property and casualty insurance operations that were in runoff.  AIIC is a property and casualty insurance operation that was previously reported in discontinued operations. The sale is subject to various closing conditions and is expected to be completed in the second half of 2009.  Aon anticipates incurring a pretax loss of approximately $191 million on the sale of these operations, which was recorded in 2008 in income (loss) from discontinued operations.

As of November 30, 2006, in connection with the sale of Aon Warranty Group (“AWG’), Aon sold Virginia Surety Company (“VSC”).  VSC remains liable to policyholders of the P&C operations to the extent

10

reinsurers of the property and casualty businesses do not meet their obligations.  In connection with the AWG sale, Aon provided an indemnification which protects the purchaser from the credit exposure related to the property and casualty balances that were reinsured.  These reinsurance recoverables amount to $597 million at June 30, 2009.  Trust balances and letters of credit offsetting these reinsurance recoverables totaled approximately $118 million at June 30, 2009. The liability balance reflecting the estimated fair value of this indemnification was $9 million at June 30, 2009.  The Company is not aware of any event of default by any reinsurer which would require it to satisfy the indemnification.  In conjunction with the sale of the P&C operations, the buyer will assume the indemnification with respect to these reinsurance balances.

AIS Management Corporation

In 2008, Aon reached a definitive agreement to sell AIS Management Corporation (“AIS”), which was previously included in the Risk and Insurance Brokerage Services segment, to Mercury General Corporation, for $120 million in cash at closing, plus a potential earn-out of up to $35 million payable over the two years following the completion of the agreement.  The disposition was completed in January 2009 and resulted in a pretax gain of $86 million in first quarter 2009.

Accident, Life & Health Operations

On April 1, 2008, the Company sold its Combined Insurance Company of America (“CICA”) subsidiary to ACE Limited and its Sterling Life Insurance Company (“Sterling”) subsidiary to Munich Re Group.  These two subsidiaries were previously included in the Company’s former Insurance Underwriting segment.  After final adjustments, Aon received $2.525 billion in cash for CICA and $341 million in cash for Sterling.  Additionally, CICA paid a $325 million dividend to Aon before the sale transaction was completed.  A pretax gain of $1.4 billion was recognized in the second quarter 2008 on the sale of these businesses.

7.Restructuring

Aon Benfield Restructuring Plan

The Company announced a global restructuring plan in conjunction with its merger with Benfield Group Limited (“Aon Benfield Plan”) in 2008.  The restructuring plan is intended to integrate and streamline operations across the combined Aon Benfield organization.  The Aon Benfield Plan includes an estimated 500 to 700 job eliminations.  As of June 30, 2009, approximately 400 jobs have been eliminated under the Plan.  Additionally, duplicate space and assets will be abandoned.  The Company recorded $21 million and $30 million of restructuring and related expenses in the second quarter and six months 2009, respectively.  The Company estimates that the Aon Benfield Plan will result in costs totaling approximately $185 million, of which $104 million was recorded in connection with the Benfield merger and is included as part of the Benfield purchase price allocation, and $81 million of which will result in charges to earnings.  All costs associated with the Aon Benfield Plan are included in the Risk and Insurance Brokerage Services segment.  Charges related to the restructuring are included in compensation and benefits, other general expenses, and depreciation and amortization in the accompanying condensed consolidated statements of income.  The Company expects the restructuring activities and related expenses to affect continuing operations into 2011.

(1)Actual costs, when incurred, will vary due to changes in the assumptions built into this plan.  Significant assumptions likely to change when plans are finalized and approved include, but are not limited to, changes in severance calculations, changes in the assumptions underlying sublease loss calculations due to changing market conditions, and changes in the overall analysis that might cause the Company to add or cancel component initiatives.

(2)Other costs associated with restructuring initiatives, including moving costs, consulting fees and legal fees, are recognized when incurred.

2007 Restructuring Plan

In 2007, the Company announced a global restructuring plan intended to create a more streamlined organization and reduce future expense growth to better serve clients (“2007 Plan”).  The 2007 Plan includes an estimated 3,900 job eliminations.  As of June 30, 2009, approximately 2,300 positions have been eliminated.  The Company also expects to close or consolidate several offices resulting in sublease losses or lease buy-outs.  The Company estimates that the 2007 Plan will result in cumulative pretax charges totaling approximately $550 million.  Expenses will include workforce reduction, lease consolidation costs, asset impairments, as well as other expenses necessary to implement the restructuring initiative.  Costs related to the restructuring are included in compensation and benefits, other general expenses and depreciation and amortization in the accompanying condensed consolidated statements of income.  The Company expects the restructuring and related expenses to affect continuing operations through the end of 2009.

9.Debt

In 1997, Aon created Aon Capital A, a wholly-owned statutory business trust (“Trust”), for the purpose of issuing mandatorily redeemable preferred capital securities (“Capital Securities”). Aon received cash and an investment in 100% of the common equity of Aon Capital A by issuing 8.205% Junior Subordinated Deferrable Interest Debentures (the “Debentures”) to Aon Capital A. These transactions were structured such that the net cash flows from Aon to Aon Capital A matched the cash flows from Aon Capital A to the third party investors. Aon determined that it was not the primary beneficiary of Aon Capital A, a VIE, and, thus reflected the Debentures as long-term debt.

During the first half of 2009, Aon repurchased $15 million face value of the Capital Securities for approximately $10 million, resulting in a $5 million gain reflected in other (income) expense in the condensed consolidated statement of income.

To facilitate the legal release of the obligation created through the Debentures associated with this repurchase and future repurchases, Aon dissolved the Trust effective June 25, 2009. This dissolution resulted in the exchange of the Capital Securities held by third parties for the Debentures. Also in connection with the dissolution of the Trust, the $24 million of common equity of Aon Capital A held by Aon was exchanged for $24 million of Debentures, which were then cancelled.

Following these actions, $687 million of Debentures remain outstanding as of June 30, 2009. The Debentures 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.

Also during the second quarter 2009, $100 million of short-term debt related to a VIE where Aon is the primary beneficiary was repaid.

Subsequent to quarter end, on July 1, 2009, an indirect wholly-owned subsidiary of Aon issued €500 million ($703 million at June 30, 2009 exchange rates) of 6.25% senior unsecured debentures due on July 1, 2014.  The principal and interest on the debentures is unconditionally and irrevocably guaranteed by Aon.  Proceeds from the offering were used to repay the Company’s $677 million outstanding indebtedness under its Euro credit facility. Consequently, the amount due under the Euro credit facility at June 30, 2009 has been included within short-term debt in the condensed consolidated statement of financial position.

10.Equity

Common Stock

During the first six months of 2009, Aon issued 966,000 new shares of common stock for employee benefit plans.  In addition, Aon issued approximately 5.0 million shares of treasury stock for employee benefit programs and 157,000 shares in connection with employee stock purchase plans.

Aon’s Board of Directors has authorized the Company to repurchase up to $4.6 billion of its outstanding common stock.  Shares may be repurchased through the open market or in privately negotiated transactions from time to time, based on prevailing market conditions and will be funded from available capital.  Any repurchased shares will be available for employee stock plans and for other corporate purposes.  The Company did not repurchase any shares in first quarter 2009. The Company repurchased approximately 3.4 million shares at a cost of $125 million in the second quarter 2009.  Since inception of its share repurchase program in 2005, the Company has repurchased a total of 94.2 million shares for an aggregate cost of $3.9 billion.  As of June 30, 2009, the Company remained authorized to purchase up to $730 million of additional shares under the current stock repurchase program.  The timing and amount of future purchases will be based on market and other conditions.

There are also 22.4 million shares of common stock held in treasury at June 30, 2009 which are restricted as to their reissuance.

On January 30, 2009, the Aon Board of Directors adopted an amendment to the U.S. defined benefit pension plan whereby effective April 1, 2009 the Company ceased crediting future benefits relating to salary and service.  As a result of the U.S. plan amendment, the Company remeasured its pension expense for 2009 to reflect a new discount rate of 7.08%, the year-to-date decline in plan assets and change in amortization basis to the expected average remaining life of plan participants.  The remeasurement resulted in a $163 million improvement in the funded status of Aon’s U.S. plan. Additionally, the Company recognized a curtailment gain of $83 million in first quarter 2009, which was reported in compensation and benefits in the condensed consolidated statements of income.

Also during the first quarter 2009, an additional curtailment gain of $10 million was recognized in discontinued operations resulting from the sale of CICA.  The curtailment gain relates to the Company’s U.S. Retiree Health and Welfare Plan in which CICA employees were allowed to participate through the end of 2008, pursuant to the terms of the sale.  In the second quarter 2008, a pension curtailment gain of $12 million was recognized in discontinued operations resulting from the sale of CICA.

During the second quarter 2009, Aon recorded a $5 million curtailment charge attributable to a remeasurement resulting from the decision to cease service accruals in the Canadian plans beginning in 2010, which was reported in compensation and benefits in the condensed consolidated statements of income.

In 2009, Aon plans to contribute $26 million and $393 million to its U.S. and material international defined benefit pension plans, respectively.  As of June 30, 2009, contributions of $11 million have been made to the U.S. pension plans and $287 million to its material international pension plans.

During the first half of 2009, the Company converted its stock administration system to a new service provider.  In connection with this conversion, a reconciliation of the methodologies utilized was performed, which resulted in a $10 million reduction of expense for the six months ended June 30, 2009.

Stock Awards

During the first six months of 2009, the Company granted approximately 2 million shares in connection with the completion of the 2006 Leadership Performance Plan (“LPP”) cycle and approximately 3.1 million restricted shares in connection with the Company’s incentive compensation plans.

A summary of the status of Aon’s non-vested stock awards is as follows (shares in thousands):

Stock Options

In 2008 and prior years, Aon used historical data to estimate option exercise and employee terminations within the lattice-binomial option-pricing model, stratified between executives and key employees.  Beginning in 2009, after reviewing additional historical data, the valuation model stratifies employees between those receiving LPP options, Special Stock Plan (“SSP”) options, and all other option grants.  The Company believes that this stratification better represents prospective stock option exercise patterns.

The weighted average assumptions, the weighted average expected life and estimated fair value of employee stock options are summarized as follows:

	Three months ended June 30, 2009						Six months ended June 30, 2009
	LPP Options			SSP Options			LPP Options			SSP Options			All Other Options
Weighted average volatility	35.7		%	35.7		%	35.5		%	35.7		%	35.5		%

Weighted average expected life, in years	5.7			5.1			5.7
Weighted average estimated fair value per share	$	13.32		$	11.26		$	12.81

During the first six months of 2009, the Company granted approximately 1 million stock options with an exercise price of $39 per share in connection with the 2009 LPP Plan and approximately 400,000 stock options with an exercise price of $37 per share in connection with the Company’s incentive compensation plans.

A summary of the status of Aon’s stock options and related information is as follows (shares in thousands):

	Six months ended June 30,

The weighted average remaining contractual life, in years, of outstanding options was 4.5 years and 5.0 years at June 30, 2009 and 2008, respectively.

The aggregate intrinsic value represents the total pretax intrinsic value, based on options with an exercise price less than the Company’s closing stock price of $37.87 as of June 30, 2009, which would have been received by the option holders had those option holders exercised their options as of that date.  At June 30, 2009, the aggregate intrinsic value of options outstanding was $119 million, of which $69 million was exercisable.

Other information related to the Company’s stock options is as follows (in millions):

	Three months ended June 30,				Six months ended June 30,

Unamortized deferred compensation expense, which includes both options and awards, amounted to $339 million as of June 30, 2009, with a remaining weighted-average amortization period of approximately 2.1 years.

13.Financial Instruments

Aon is exposed to market risk from changes in foreign currency exchange rates, interest rates and equity security prices.  To manage the risk related to these exposures, Aon enters into various derivative transactions.  The derivatives have the effect of reducing Aon’s market risks by creating offsetting market exposures.  Aon does not enter into derivative transactions for trading purposes.

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 using International Swaps and Derivatives Association (“ISDA”) master agreements, collateral and credit support arrangements, entering into non-exchange-traded derivatives with highly-rated major financial institutions and by using exchange-traded instruments.  Aon monitors the credit-worthiness of, and exposure to, its counterparties.  As of June 30, 2009, all net derivative liability positions were entered into pursuant to terms of ISDA master agreements, and were free of credit risk contingent features.

Accounting Policy for Derivative Instruments

All derivative instruments are recognized in the condensed consolidated statements of financial position at fair value. Unless otherwise noted, derivative instruments with a positive fair value are reported in other assets and derivative instruments with a negative fair value are reported in other liabilities in the condensed consolidated statements of financial position.  Where Aon has entered into master netting agreements with counterparties, the derivative positions are netted by counterparty and are reported accordingly in other assets or other liabilities.  Changes in the fair value of derivative instruments are recognized immediately in earnings, unless the derivative is designated as a hedge and qualifies for hedge accounting.

21

Accounting principles identify three hedging relationships where a derivative (hedging instrument) may qualify for hedge accounting: (i) a hedge of the change in fair value of a recognized asset or liability or firm commitment (“fair value hedge”), (ii) a hedge of the variability in cash flows from a recognized variable-rate asset or liability or forecasted transaction (“cash flow hedge”), and (iii) a hedge of the net investment in a foreign subsidiary (“net investment hedge”).  Under hedge accounting, recognition of derivative gains and losses can be matched in the same period with that of the hedged exposure and thereby minimize earnings volatility.

In order for a derivative to qualify for hedge accounting, the derivative must be formally designated as a fair value, cash flow, or a net investment hedge by documenting the relationship between the derivative and the hedged item.  The documentation will include a description of the hedging instrument, the hedge item, the risk being hedged, Aon’s risk management objective and strategy for undertaking the hedge, the method for assessing the effectiveness of the hedge, and the method for measuring hedge ineffectiveness.  Additionally, the hedge relationship must be expected to be highly effective at offsetting changes in either the fair value or cash flows of the hedged item at both inception of the hedge and on an ongoing basis.  Aon assesses the ongoing effectiveness of its hedges and measures and records hedge ineffectiveness, if any, at the end of each quarter.

For a fair value hedge, the change in fair value of the hedging instrument and the change in fair value of the hedged item attributable to the risk being hedged are both recognized currently in earnings.  For a cash flow hedge, the effective portion of the change in fair value of a hedging instrument 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 net investment hedge, the effective portion of the change in fair value of the hedging instrument is reported in OCI as part of the cumulative translation adjustment, while the ineffective portion is recognized immediately in earnings.

Changes in the fair value of a derivative that is not designated as an accounting hedge (known as an “economic hedge”) are recorded in either investment income or other general expenses (depending on the hedged exposure and the Company’s policy) in the current period’s condensed consolidated statement of income.

Aon discontinues hedge accounting prospectively when (1) the derivative expires or is sold, terminated, or exercised, (2) it determines that the derivative is no longer effective in offsetting changes in the hedged item’s fair value or cash flows, (3) a hedged forecasted transaction is no longer probable of occurring in the time period described in the hedge documentation, (4) the hedged item matures or is sold, or (5) management elects to discontinue hedge accounting voluntarily.

When hedge accounting is discontinued because the derivative no longer qualifies as a fair value hedge, Aon will continue to carry the derivative in the condensed consolidated statements of financial position at its fair value, recognize subsequent changes in the fair value of the derivative in current-period earnings, cease to adjust the hedged asset or liability for changes in its fair value, and begin to amortize the hedged item’s cumulative basis adjustment into earnings over the remaining life of the hedged item using a method that approximates the level-yield method.

When hedge accounting is discontinued because the derivative no longer qualifies as a cash flow hedge, Aon will continue to carry the derivative in the condensed consolidated statements of financial position at its fair value, recognize subsequent changes in the fair value of the derivative in current-period earnings, and continue to defer the derivative gain or loss in accumulated OCI until the hedged forecasted transaction affects earnings.  If the hedged forecasted transaction is probable of not occurring

22

in the time period described in the hedge documentation or within a two month period of time thereafter, the deferred derivative gain or loss would be reclassified immediately to earnings.

Foreign Exchange Risk Management

Certain of Aon’s foreign brokerage subsidiaries, primarily in the U.K., receive revenues in currencies (primarily in U.S. dollars and Euros) that differ from their functional currencies.  The foreign subsidiary’s functional currency revenue will fluctuate as the currency exchange rates change.  To reduce this variability, Aon uses foreign exchange forward contracts and over-the-counter options to hedge the foreign exchange risk of the forecasted revenue for up to a maximum of five years in the future.  Aon has designated these derivatives as cash flow hedges of its forecasted foreign currency denominated revenue.  As of June 30, 2009, an $8 million pretax gain has been deferred to OCI, a $6 million loss is expected to be reclassified to earnings as an adjustment to other general expenses in the next twelve months.  Deferred gains or losses will be reclassified from OCI to other general expenses when the hedged revenue is recognized.  The hedge had no material ineffectiveness in the first six months of 2009.

As of June 30, 2009, the Company had the following outstanding foreign exchange forward and option contracts that were entered into to hedge forecasted revenues and which qualify as cash flow hedges (in millions):

	Notional Amounts
Forecasted revenues	2009		2010		2011		2012
U.S. Dollar	$	119	$	312	$	246	$	25
Euro	26		37		23		16

Aon also uses foreign exchange forward contracts, which have not been designated as hedges for accounting purposes, to hedge economic risks that arise from fluctuations in the currency exchange rates.  Changes in the fair value of these derivatives are recorded in other general expenses in the condensed consolidated statements of income.  As of June 30, 2009, the total notional amount of the Company’s foreign exchange forward contracts related to these derivatives was $150 million.

Aon uses foreign exchange forward and over-the-counter option contracts to reduce the impact of foreign currency fluctuations on the translation of the financial statements of Aon’s foreign operations and to manage the currency exposure of Aon’s global liquidity profile.  These derivatives are not eligible for hedge accounting treatment and changes in the fair value of these derivatives are recorded in other general expenses in the condensed consolidated statements of income.  As of June 30, 2009, the total notional amount of the Company’s foreign exchange forward and over-the-counter option contracts related to these derivatives was $157 million.

Aon also uses foreign currency forward contracts to offset foreign exchange risk associated with foreign denominated (primarily British pounds) intercompany notes.  These derivatives were not designated as a hedge because changes in their fair value were largely offset in earnings by remeasuring the notes for changes in spot exchange rates.  Changes in the fair value of these derivatives were recorded in other general expenses in the condensed consolidated statements of income. As of June 30, 2009, the total notional amount of the Company’s foreign exchange forward contracts related to these derivatives was $123 million.

Aon also uses foreign currency option contracts to hedge its net investments in foreign operations.  During the first six months of 2009, this hedge had no ineffectiveness, and a $21 million cumulative pretax gain has been included in OCI at June 30, 2009.  As of June 30, 2009, Aon has received collateral

23

of $18 million from the counterparty for this hedge.  As of June 30, 2009, the total notional amount of the Company’s foreign currency option contracts related to this hedge was $574 million.

In 2005, Aon subsidiaries entered into cross-currency swaps to hedge the foreign currency risks associated with foreign denominated fixed-rate term intercompany borrowings.  These swaps have been designated as cash flow hedges.  As of June 30, 2009, a $3 million pretax gain had been deferred to OCI; a $2 million loss is expected to be reclassified to earnings as an adjustment to interest expense in the next twelve months.  Reclassification from OCI will offset the related transaction gain or loss arising from the remeasurement of the borrowing due to changes in spot exchange rates.  This hedge had no material ineffectiveness in the first six months of 2009.  As of June 30, 2009, the total notional amount of the Company’s cross-currency swaps related to this hedge was $140 million.

In 2008, Aon subsidiaries entered into cross-currency swaps to hedge the foreign currency risks associated with foreign denominated fixed-rate term intercompany receivables.  These swaps have been designated as cash flow hedges.  As of June 30, 2009, a $15 million pretax loss had been deferred to OCI, $7 million of which is expected to be reclassified to earnings as an adjustment to other general expenses in the next twelve months.  Reclassification from OCI will offset the related transaction gain or loss arising from the remeasurement of the receivable due to changes in spot exchange rates.  This hedge had no material ineffectiveness in the first six months of 2009.  As of June 30, 2009, the total notional amount of the Company’s cross-currency swaps related to this hedge was $197 million.

Several of Aon’s subsidiaries have negotiated outsourcing service agreements in currencies that differ from their functional currencies; primarily the Philippine Peso and the Indian Rupee.  The subsidiary’s functional currency equivalent of the expense will fluctuate as the currency exchange rates change.  To reduce this variability, Aon uses foreign exchange forward contracts to hedge the foreign exchange risk associated with the forecasted expense incurred for the life of the service agreements or up to six years.  Aon has designated these derivatives as cash flow hedges of its forecasted foreign currency denominated expense.  As of June 30, 2009, a $7 million pretax loss has been deferred to OCI, $2 million of which is expected to be reclassified to earnings as an adjustment to other general expenses in the next twelve months.  Deferred gains or losses will be reclassified from OCI to other general expenses when the hedged expense is recognized.  The hedge did not have any ineffectiveness in the first six months of 2009.

As of June 30, 2009, the Company had the following outstanding foreign exchange forward contracts that were entered into to hedge forecasted expenses and which qualify as cash flow hedges (in millions):

	Notional Amounts
Forecasted expenses	2009		2010		2011		2012
Indian Rupee	$	7	$	10	$	10	$	4
Philippine Peso	1		2		2		1

In May 2009, Aon entered into a sponsorship agreement under which Aon is required to make payments in British pounds over the next four years pursuant to the terms of the contract.  As a result, the Company is exposed to foreign exchange transaction risk and has hedged its exposure using over-the-counter options.  Aon has designated these derivatives as cash flow hedges of its forecasted foreign currency denominated expense.  As of June 30, 2009, a $1 million pretax loss has been deferred to OCI.  Deferred gains or losses will be reclassified from OCI to other general expenses when the hedged expense is recognized.  This hedge did not have any ineffectiveness in the first six months of 2009.  As of June 30, 2009, the total notional amount of the Company’s over-the-counter options related to this hedge was $73 million.

Interest Rate Risk Management

Aon enters into receive-fixed-pay-floating interest rate swaps which are designated as cash flow hedges of the benchmark interest rate risk component of a portion of Aon’s U.S. dollar, Euro, Australian dollar, Canadian dollar and British pound denominated brokerage funds held on behalf of clients and other operating funds.  Forecasted interest receipts earned on deposit balances are hedged up to a maximum of three years into the future.  Changes in the fair value of the swaps are recorded in OCI and will be reclassified to earnings as an adjustment to investment income over the term of the swap.  As of June 30, 2009, a $19 million pretax gain related to this hedge was recorded in OCI, $17 million of which is expected to be reclassified to earnings as an adjustment to investment income in the next twelve months.  This hedge had no material ineffectiveness in the first six months of 2009.

As of June 30, 2009, the Company had the following outstanding interest rate swaps that were entered into to hedge the interest rate exposure of the forecasted interest receipts earned on short-term fund balances (in millions):

	Notional Amounts
Fund balances	2009		2010		2011
U.S. Dollar	$	1,000	$	750	$	100
Euro	337		253		84
All other	157		157		25

14.Premium Finance Operations

Some of Aon’s U.S., U.K., Canadian, and Australian subsidiaries have originated short-term loans (generally with terms of 12 months or less) to businesses to finance their insurance premium obligations, and then have sold these premium finance agreements in securitization transactions that meet the criteria for sale accounting under current accounting principles.  In December 2008, Aon signed a definitive agreement to sell the U.S. operations of the premium finance business (Cananwill). In connection with Aon’s sale of its U.S. premium finance business, Aon has guaranteed the collection of the principal amount of the premium finance notes sold to the buyer, which, at June 30, 2009, was $170 million, if losses exceed the historical credit loss reserve for the business.  Historical losses in this business have been very low since the premium finance notes are generally fully collateralized by the lender’s right, in the event of non-payment, to cancel the underlying insurance contract and collect the unearned premium from the insurance carrier.  The Company does not expect to incur any significant losses related to this guarantee. This disposition was completed in February 2009.

26

In the U.K., premium finance agreements have been sold to special purpose entities (“SPEs”), which are considered QSPEs, as defined. The QSPEs fund their purchases of premium finance agreements by selling undivided beneficial interests in the agreements to multi-seller commercial paper conduit SPEs sponsored by unaffiliated banks (“Bank SPEs”). In Canada and Australia, undivided interests in the premium finance agreements have been sold directly to Bank SPEs.  The Bank SPEs are variable interest entities as defined under current accounting principles.

The QSPEs used in the U.K are not consolidated in Aon’s financial statements because the criteria for sale accounting have been met. For the Canadian and Australian sales, the Company determined that non-consolidation of the Bank SPEs is appropriate because Aon is not their primary beneficiary.  Aon’s variable interest in the Bank SPEs in these jurisdictions is limited to the retained interests in premium finance agreements sold to the Bank SPEs.  The Company reviews all material off-balance sheet transactions annually or whenever a reconsideration event occurs for the continued propriety of its accounting.

The total amount that can be advanced by the Bank SPEs on premium finance agreements sold to them at any one time is limited by the sale agreements. The limit was $267 million at June 30, 2009.  The outstanding balance of sold portfolios at June 30, 2009 was $247 million, and the Bank SPEs had advanced $194 million.  The outstanding balance of sold portfolios at December 31, 2008 was $1.1 billion, and the Bank SPEs had advanced $981 million.

Aon records gains on the sale of premium finance agreements.  When Aon calculates the gain, all costs expected to be incurred for the relevant Bank SPEs are included.  The gains, which are included in commissions, fees and other revenue in the condensed consolidated statements of income, were $8 million and $15 million for the three months ended June 30, 2009 and 2008, respectively, and $14 million and $32 million for the six months ended June 30, 2009 and 2008, respectively.

Aon records its retained interest in the sold premium finance agreements at fair value, and reports it in receivables in the condensed consolidated statements of financial position.  Aon estimates fair value by discounting estimated future cash flows using discount rates that are commensurate with the underlying risk, expected future prepayment rates, and credit loss estimates.

Aon also retains servicing rights for sold agreements, and earns servicing fee income over the servicing period.  Because the servicing fees represent adequate compensation for the servicing of the receivables, the Company has not recorded any servicing assets or liabilities.

The third-party bank sponsors or other participants in the Bank SPEs provide the liquidity support and bear the credit risks on the receivables, subject to limited recourse, in the form of over-collateralization provided by Aon (and other sellers) as required by the sales agreements.  The over-collateralization of the sold receivables represents Aon’s maximum exposure to credit-related losses, and was approximately $61 million at June 30, 2009.  The Company continually reviews the retained interest in the sold portfolio, taking into consideration credit loss trends in the sold portfolio, conditions in the credit markets and other factors, and adjusts its carrying value accordingly.

27

With the exception of the Australian sales agreements, all the other sales agreements require Aon to meet the following covenants:

·consolidated net worth, as defined, of at least $2.5 billion,

·consolidated EBITDA to consolidated net interest of at least 4 to 1, and

·consolidated indebtedness to consolidated EBITDA of no more than 3 to 1.

The Company renewed the Canadian and U.K. sales agreements in the fourth quarter 2008 and the Australian sales agreement in the second quarter of 2009. The current environment in the credit market influenced the renewal process, the renewed terms are more restrictive, and the over-collateralization requirements were increased.

In June and July of 2009, the Company entered into agreements with third parties with respect to Aon’s premium finance businesses in the U.K., Canada and Australia (collectively, the “Cananwill International Agreements”).  As a result of the Cananwill International Agreements the third parties will begin originating, financing and servicing premium finance loans generated by referrals from Aon’s brokerage operations.  The Company expects to cease financing and servicing premium finance loans by the end of the fourth quarter of 2009.  The third parties did not acquire the existing portfolio of Aon’s premium finance loans, and as such, the Company did not extend any guarantees under these agreements.

15.Variable Interest Entities

Aon has the following VIEs that have been consolidated at June 30, 2009:

·Globe Re Limited (“Globe Re”), provided reinsurance coverage for a defined portfolio of property catastrophe reinsurance contracts underwritten by a third party for a limited period which ended June 1, 2009;

·Juniperus Insurance Opportunity Fund Limited (“Juniperus”), which is an investment vehicle that invests in an actively managed and diversified portfolio of insurance risks; and

·Juniperus Capital Holdings Limited (“JCHL”), which provides investment management and related services to Juniperus.

Globe Re is deemed to be a VIE since the equity investors at risk lack a controlling financial interest.  Aon owns an 85% equity economic interest in Globe Re, is deemed to be the primary beneficiary and consolidates Globe Re.  In connection with the winding up of its operations, during June 2009, Globe Re repaid its $100 million of short-term debt from available cash.  In early July 2009, Aon’s equity investment in Globe Re was repaid.  Globe Re had assets and liabilities of $56 million and $2 million, respectively, at June 30, 2009 and $187 million and $105 million, respectively, at December 31, 2008.  Aon recognized $4 million and $8 million of pretax income from Globe Re in the second quarter and six months 2009, respectively.  Globe Re will be fully liquidated in third quarter 2009.

Aon holds a 40% equity interest in the Juniperus Class A shares and bears a majority of the expected returns and losses.  Aon has a 73% voting and economic interest in JCHL and absorbs a majority of JCHL’s expected losses.  Aon is considered the primary beneficiary of both companies, and as such these entities have been consolidated.  Juniperus/JCHL had assets and liabilities of $175 million and $35 million, respectively, at June 30, 2009 and $121 million and $22 million, respectively, at December 31, 2008.  Aon recognized $4 million of pretax income from Juniperus/JCHL for both the second quarter and six months 2009.  Aon’s potential loss at June 30, 2009 is limited to its investment in the VIEs,

28

which is $63 million for Juniperus/JCHL.

16.Fair Value

Accounting standards establish a three tier fair value hierarchy which prioritizes the inputs used in measuring fair value as follows:  

·Level 1 – observable inputs such as quoted prices for identical assets in active markets;

·Level 2 – inputs other than quoted prices for identical assets in active markets, that are observable either directly or indirectly; and

·Level 3 – unobservable inputs in which there is little or no market data which requires the use of valuation techniques and the development of assumptions.

The following table presents, for each of the fair-value hierarchy levels, the Company’s assets and liabilities that are measured at fair value on a recurring basis at June 30, 2009 (in millions):

			Fair Value Measurements Using
			Quoted Prices in		Significant		Significant
			Active Markets		Other		Unobservable
	Balance at		for Identical		Observable		Inputs

(1)   Includes $2,546 million of money market funds and $141 million of highly liquid debt securities that are classified as fiduciary assets, short-term investments or cash equivalents in the condensed consolidated statements of financial position, depending on their nature and initial maturity. See Note 8 for additional information regarding the Company’s investments.

The following methods and assumptions are used to estimate the fair values of our financial instruments:

Money market funds and highly liquid debt securities are carried at cost and amortized cost, respectively, as an approximation of fair value.  Based on market convention, the Company considers cost a practical and expedient measure of fair value.

Other investments carried at fair value consists primarily of the Company’s investment in PEPS I.  Fair value is based on valuations received from the general partners of the limited partnership interests held by PEPS I.

Derivatives are carried at fair value, based upon industry standard valuation techniques that use, where possible, current market-based or independently sourced pricing inputs, such as interest rates, currency exchange rates, or implied volatilities.

Retained interests in the sold premium finance agreements of Aon’s premium financing operations are recorded at fair value by discounting estimated future cash flows using discount rates that are commensurate with the underlying risk, expected future prepayment rates, and credit loss estimates.

Guarantees are carried at fair value, which is based on discounted estimated future cash flows using published historical cumulative default rates and discount rates commensurate with the underlying exposure.

The fair value of debt is based on quoted market prices or estimates using discounted cash flow analyses based on current borrowing rates for similar types of borrowing arrangements.

17.Contingencies

Aon and its subsidiaries are subject to numerous claims, tax assessments, lawsuits and proceedings that arise in the ordinary course of business.  The damages claimed in these matters are or may be substantial, including, in many instances, claims for punitive, treble or extraordinary damages.  Aon has purchased errors and omissions (“E&O”) insurance and other appropriate insurance to provide protection against losses that arise in such matters.  Accruals for these items, and related insurance receivables, when applicable, have been provided to the extent that losses are deemed probable and are reasonably estimable.  These accruals and receivables are adjusted from time to time as developments warrant.  Amounts related to settlement provisions are recorded in other general expenses in the condensed consolidated statements of income.

At the time of the 2004-05 investigation of the insurance industry by the Attorney General of New York (“NYAG”) and other regulators, purported classes of clients filed civil litigation against Aon and other companies under a variety of legal theories, including state tort, contract, fiduciary duty, antitrust and statutory theories and federal antitrust and Racketeer Influenced and Corrupt Organizations Act (“RICO”) theories.  The federal actions were consolidated in the U.S. District Court for the District of New Jersey, and a state court collective action was filed in California.  In the New Jersey actions, the Court dismissed plaintiffs’ federal antitrust and RICO claims in separate orders in August and October 2007, respectively.  Plaintiffs have appealed these dismissals.  Aon believes it has meritorious defenses in all of these cases and intends to vigorously defend itself against these claims.  The outcome of these lawsuits, and any losses or other payments that may occur as a result, cannot be predicted at this time.

Also at the time of the NYAG investigation, putative classes filed actions against Aon in the U.S. District Court for the Northern District of Illinois under the federal securities laws and ERISA.  Plaintiffs in the federal securities class action submitted purported expert reports estimating a range of alleged damages of $353 million to $490 million, and plaintiffs in the ERISA class actions submitted revised purported expert reports estimating a range of alleged damages of $74 million to $349 million.  Aon submitted expert reports in opposition concluding that plaintiffs’ theories of liability and causation are meritless and that, in any event, plaintiffs incurred no damages.  Aon believes it has meritorious defenses in all of these cases and has vigorously defended itself against these claims.  In June 2009, Aon reached agreement on a proposed settlement of the federal securities class action under which Aon would pay $30 million to the class.  This

31

settlement is subject to a process requiring final approval by the trial court and a possible appeal. The outcome of these lawsuits, and any losses or other payments that may occur as a result, cannot be predicted at this time.  On June 12, 2009, Aon entered into two settlement agreements with XL Insurance (Bermuda) Ltd. resulting in the receipt of $26 million by Aon.  The agreements resolve, among other things, a lawsuit between XL and Aon relating to whether XL’s policy covered losses relating to, among other things, the above-referenced matters.

Following inquiries from regulators, the Company commenced an internal review of its compliance with certain U.S. and non-U.S. anti-corruption laws, including the U.S. Foreign Corrupt Practices Act (“FCPA”).  An outside law firm with significant experience in the area is overseeing the review.  Certain governmental agencies, including the U.K. Financial Services Authority (“FSA”), the U.S. Securities and Exchange Commission (“SEC”), and the U.S. Department of Justice (“DOJ”), have also been investigating these matters.  Aon is fully cooperating with these investigations, and has agreed with the U.S. agencies to toll any applicable statute of limitations pending completion of the investigations.  On January 8, 2009, the FSA and Aon announced a settlement under which the FSA concluded its investigation by assessing a £5.25 million fine on Aon Limited, Aon’s principal U.K. brokerage subsidiary.  Based on current information, the Company is unable to predict at this time when the remaining SEC and DOJ matters will be concluded, or what regulatory or other outcomes may result.

A financial institution in the U.K. called Standard Life Assurance Ltd. brought an action in London Commercial Court against Aon seeking more than £50 million for alleged errors or omissions in the placement of a professional indemnity policy with certain underwriters.  In a preliminary decision issued on February 13, 2008, the court construed the relevant policy language to excuse the underwriters from paying Standard Life and concluded that Aon was negligent in not seeking changes to the language.  Aon filed an interlocutory appeal of this preliminary decision.  In July 2008, Aon reached a settlement with the underwriters under which the underwriters agreed to pay a portion of the ultimate recovery by Standard Life in exchange for Aon dropping its appeal of the preliminary decision.  In July 2009, Aon executed a settlement agreement with Standard Life under which Aon agreed to pay £46 million.  Such amount is partially offset by an agreed receivable from third parties providing indemnification to Aon.

A putative class action, Buckner v. Resource Life, is pending in state court in Columbus, Georgia against a former subsidiary of Aon, Resource Life Insurance Company.  The complaint alleges that Resource Life, which wrote policies insuring repayment of auto loans, was obligated to identify and return unearned premium to policyholders whose loans terminated before the end of their scheduled terms.  In connection with the sale of Resource Life in 2006, Aon agreed to indemnify Resource Life’s buyer in certain respects relating to this action.  In April 2009, a magistrate appointed by the court recommended that the court issue an order holding, inter alia, that a large number of policyholders should be presumed to be entitled to unearned premium refunds of as-yet-undetermined amounts. The court has not yet determined whether to accept the recommendation or whether to certify a class.  Aon believes that Resource Life has meritorious defenses and is vigorously defending this action.  The outcome of the action, and the amount of any losses or other payments that may result, cannot be predicted at this time.

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.

18.Business Segments

Aon classifies its businesses into two operating segments: Risk and Insurance Brokerage Services and Consulting.

·The Risk and Insurance Brokerage Services segment consists primarily of Aon’s retail and reinsurance brokerage operations, as well as related insurance services, including underwriting management, captive insurance company management services, investment banking products and services, and premium financing.  Aon sold its U.S. operations of the premium finance business of Cananwill in first quarter 2009.

·The Consulting segment provides a broad range of consulting services.  These services are delivered predominantly to corporate clientele that operate in the following practice areas: Consulting Services — health and employee benefits, retirement, compensation, and strategic human capital, and Outsourcing - human resource outsourcing.

Aon’s total revenue is as follows (in millions):

Unallocated investment income and other revenue consists primarily of revenue from our equity ownership in insurance investments and income associated with invested assets not directly required to support the risk and insurance brokerage services and consulting businesses.

Unallocated expenses include administrative or other costs not attributable to the operating segments, such as corporate governance costs and the costs associated with corporate investments.  Interest expense represents the cost of worldwide debt obligations.

EXECUTIVE SUMMARY

The current global economic recession is providing significant headwind for our business.  We continue to operate in a soft insurance pricing market, as property and casualty rates continue to decline, although at a somewhat slower pace.  In addition to pricing declines, we are seeing a volume impact driven by the current economic environment, which places pressure on our business in three primary ways:

·declining insurable risks due to decreasing asset values, including property values, shipment volume, payroll and number of active employees,

·client cost-driven behavior, where clients are actively looking to reduce spending in order to meet budget reductions and increase risk retention, as a result of prioritizing their total spending, and

·sector specific weakness, including financial services, construction, private equity, and mergers and acquisitions, all of which have been particularly impacted by the current recession.

Despite this difficult market environment, we grew the business organically in our Americas retail business and our reinsurance business.  We are demonstrating expense discipline, enabling investment in our business and concurrently improving our margin.

Overall organic revenue was essentially unchanged for both the second quarter and six months 2009.  See our discussion below for more details regarding organic revenue growth.

Our consolidated pretax margins from continuing operations for the quarter declined from 11.6% in 2008 to 11.1% in 2009.  The decline was principally driven by a 4% decline in revenue, which more than offset a 3% decline in operating expenses, which include increased restructuring charges.  Year-to-date margins increased from 12.5% last year to 14.8% in 2009.  The improvement is mainly attributable to a net $78 million pension curtailment gain related to the decision to cease crediting future benefits relating to salary and service in our U.S. and Canada defined benefit pension plans, as well as restructuring savings, which more than offset lower investment income and the unfavorable impact of foreign currency translation.

The following is a summary of our second quarter and six months 2009 financial results:

·Revenue decreased $71 million or 4% for the quarter and $122 million or 3% year-to-date, as the negative effect of foreign exchange translation and significantly lower investment income was only partially offset by the impact of the Benfield merger and other acquisitions.

·Operating expenses decreased 3% and 6% for the quarter and six months 2009, respectively, due primarily to favorable foreign exchange translation and restructuring savings, partially offset by the impact of the Benfield merger and other acquisitions and higher restructuring charges.  Six months 2009 expenses were favorably impacted by the net $78 million pension curtailment gain previously described.

·Income from continuing operations attributable to Aon stockholders decreased $19 million from second quarter 2008 to $147 million.  For six months 2009, income from continuing operations attributable to Aon stockholders increased $34 million to $377 million, driven by the pension curtailment gain.

·Diluted earnings per share from continuing operations attributable to Aon’s stockholders was $0.51 for the second quarter 2009, a decrease of 6% from $0.54 per share in 2008.  Six months diluted earnings per share increased from $1.10 in 2008 to $1.30 in 2009.

37

REVIEW OF CONSOLIDATED RESULTS

General

In our discussion of operating results, we sometimes refer to supplemental information derived from our consolidated financial information.

We use supplemental information related to organic revenue growth to help us and our investors evaluate business growth from existing operations.  Organic revenue growth excludes the impact of foreign exchange rate changes, acquisitions, divestitures, transfers between business units, investment income, reimbursable expenses, and unusual items.

Supplemental organic revenue growth represents a non-GAAP measure and should be viewed in addition to, not instead of, our condensed consolidated statements of income.  Industry peers provide similar supplemental information about their revenue performance, although they may not make identical adjustments.

Because we conduct business in over 120 countries, foreign exchange rate fluctuations have an impact on our business.  In comparison to the U.S. dollar, foreign exchange rate movements may be significant and may distort true period-to-period comparisons of changes in revenue or pretax income.  Therefore, we have:

·isolated the impact of the change in currencies between periods by translating last year’s revenue and expenses at this year’s foreign exchange rates, and

·provided this form of reporting to give financial statement users more meaningful information about our operations.

Some tables in the segment discussions reconcile organic revenue growth percentages to the reported commissions, fees and other revenue growth percentages.  We disclose separately:

·the impact of foreign currency, and

·the impact from acquisitions, divestitures, transfers of business units, reimbursable expenses, and unusual items, which represent the most significant reconciling items.

Pretax margin - continuing operations	11.1		%	11.6		%	14.8		%	12.5		%

Revenue

Commissions, fees and other decreased by $25 million for the quarter and $51 million for six months.  The 1% decrease in both periods was driven by the negative impact from foreign currency translation, which was $171 million for the quarter and $361 million for six months, partially offset by inclusion of Benfield’s revenue in 2009 results. Overall organic revenue remained flat for both the quarter and the six month period.

Investment income decreased $46 million for the quarter and $71 million for six months reflecting the impact of lower interest rates, lower investment balances, and the negative impact of foreign currency translation.

Expenses

Compensation and benefits decreased $9 million or 1% for the quarter and $149 million or 6% for six months.  For the quarter, the decrease was driven by a $111 million favorable impact from foreign currency translation and restructuring savings, partially offset by $35 million of higher restructuring costs and higher expenses due to the inclusion of Benfield’s operations in 2009. On a year-to-date basis, the decrease is due to a $234 million favorable impact from foreign currency translation, restructuring savings, and a net $78 million pension curtailment gain related to the decision to cease crediting future benefits relating to salary and service in our U.S. and Canadian defined benefit pension plans.  These items were partially offset by higher expenses from the inclusion of Benfield’s operations in 2009 and $19 million in higher restructuring charges.

Other general expenses decreased $34 million or 7% for the quarter and $51 million or 6% for six months. The decline was driven by $44 million and $91 million in favorable foreign currency translation on a quarterly and year-to-date basis, respectively, lower E&O costs and reduced expenses related to the FCPA and anti-corruption reviews and related compliance initiatives, partially offset by Benfield’s cost of operations and higher restructuring charges.

39

Depreciation and amortization expense was consistent for the second quarter 2009 and 2008 and increased $10 million or 9% for six months, with favorable foreign currency translation impacting both periods. Higher amortization expense related to the Benfield merger offset the impact of asset impairments taken in 2008 as part of the 2007 restructuring plan.  The year-to-date growth is driven by the higher intangible amortization related to the Benfield merger.

Interest expense decreased $5 million for the quarter and $9 million for six months reflecting the impact of lower interest rates and favorable foreign exchange translation.

Other income of $9 million for the current quarter includes a $5 million gain on the extinguishment of $15 million of junior subordinated debentures, and a net gain on the disposal of several small operations, partially offset by costs related to the integration of Benfield.  In 2008, the $2 million of income represented a gain from the disposal of businesses. On a year-to-date basis, $2 million of other expense includes $12 million of Benfield integration costs, which more than offset gains from the extinguishment of $15 million junior subordinated debentures and net gains on disposal of operations.  In 2008, we recorded $6 million of income for six months, which included a $5 million gain on the sale of land in the U.K.

Income from Continuing Operations Before Income Taxes

Income from continuing operations before income taxes decreased $16 million or 7% to $210 million for the quarter, but increased $69 million or 14% for six months. Both periods were impacted by the unfavorable impact of foreign exchange translation, lower investment income and higher restructuring costs.  For the quarter, these items more than offset the positive impact of the Benfield merger and other acquisitions, and restructuring savings.  The year-to-date improvement, despite those items listed above, was driven by the net $78 million pension curtailment gain.

Income Taxes

The effective tax rate for continuing operations was 27.1% for second quarter 2009 compared to 25.2% for second quarter 2008.  On a year-to-date basis, the effective tax rate for continuing operations was 29.8% and 27.5% for 2009 and 2008, respectively.  The rates for all periods were favorably impacted by the benefit of statutory rate reductions in key operating jurisdictions in 2008 and the projected geographic distribution of earnings in both years.  The increase from 2008 on a year-to-date basis was driven by the tax impact of the U.S. pension curtailment gain.  The underlying tax rate for continuing operations is expected to be 28% for 2009 and was 30% for 2008.

Income from Continuing Operations

Income from continuing operations for second quarter 2009 and 2008 was $153 million and $169 million, respectively.  Diluted income per share in the second quarter 2009 was $0.51, versus $0.54 in 2008.  Income from continuing operations for six months 2009 and 2008 was $388 million and $351 million, respectively.  Diluted income per share for six months 2009 was $1.30, versus $1.10 in 2008. Currency fluctuations negatively impacted income from continuing operations in 2009 by $0.03 per diluted share in the quarter and $0.05 for six months when we translate the 2008 results at current period foreign exchange rates.  Our diluted per share calculations were favorably impacted this year by lower shares outstanding as a result of shares acquired as part of our share repurchase program.

Discontinued Operations

Second quarter income from discontinued operations was $2 million for 2009 ($0.01 per diluted share), versus income of $967 million for 2008 ($3.17 per diluted share).  Six months income from discontinued operations was $52 million for 2009 ($0.18 per diluted share), versus income of $1.0 billion for 2008 ($3.22 per diluted share).  Results for second quarter 2009 primarily reflects our FFG operations.  Results for six months 2009  include our FFG operations, as well as the gain on the sale of AIS, a curtailment gain on the post-retirement benefit plan related to the CICA disposal and residual tax settlements related to our

40

AWG disposal. Our results for second quarter and six months 2008 primarily reflect the gain on the sale of our CICA and Sterling businesses, which were sold on April 1, 2008.  Year-to-date 2008 results also include CICA and Sterling’s operations through the date of sale.  Results for AIS and FFG are also included for both the three and six month periods in 2008.

REVIEW BY SEGMENT

General

We classify our businesses into two operating segments: Risk and Insurance Brokerage Services and Consulting.

Segment revenue includes investment income generated by invested assets of that segment, as well as the impact of related derivatives. Our Risk and Insurance Brokerage Services and Consulting businesses invest funds held on behalf of clients and operating funds in short-term obligations.

Risk and Insurance Brokerage Services

Aon is a leader in many sectors of the insurance industry.  Aon was ranked in 2008 by Business Insurance as the world’s largest insurance broker, by A.M. Best as the number one global insurance brokerage based on brokerage revenues, and voted the best insurance intermediary and best reinsurance intermediary by the readers of Business Insurance.

In 2008, we experienced a soft market in many business lines/segments and in many geographic areas.  In a soft market, premium rates flatten or decrease, along with commission revenues, due to increased competition for market share among insurance carriers or increased underwriting capacity.  Prices fell throughout the year,

41

although the rate of decline slowed toward the end of the year.  In the first half of 2009, we continued to see a soft market in our retail business.  In reinsurance, pricing overall was flat to up slightly, with firmer pricing primarily in the U.S. property catastrophe areas. Changes in premiums have a direct and potentially material impact on the insurance brokerage industry, as commission revenues are generally based on a percentage of the premiums paid by insureds.

Beginning in late 2008, we faced difficult conditions as a result of unprecedented disruptions in the global economy, the repricing of credit risk and the deterioration of the financial markets.  Continued volatility and further deterioration in the credit markets may reduce our customers’ demand for our brokerage and reinsurance services and products, which could hurt our operational results and financial condition.  In addition, overall capacity in the industry could decrease if a significant insurer either fails or withdraws from writing insurance coverages that we offer our clients.  This failure could reduce our revenues and profitability, since we would no longer have access to certain lines and types of insurance.

Risk and Insurance Brokerage Services generated approximately 84% of Aon’s total operating segment revenues for both the second quarter and first six months of 2009.  Revenues are generated primarily through:

·fees paid by clients,

·commissions and fees paid by insurance and reinsurance companies, and

·interest income on funds held on behalf of clients.

Our revenues vary from quarter to quarter throughout the year as a result of:

·the timing of our clients’ policy renewals,

·the net effect of new and lost business,

·the timing of services provided to our clients, and

·the income we earn on investments, which is heavily influenced by short-term interest rates.

·The decline in Americas revenue is 2% for the quarter and 3% for six months, driven by unfavorable foreign currency translation, partially offset by organic revenue growth of 3% and 2% for the second quarter and six months, respectively, reflecting strong growth in Latin America and strong new business in our U.S. retail operations. This growth was tempered by soft market conditions, as well as overall economic weakness, especially in the construction and private equity sectors.

·U.K. revenue declined 15% for the quarter and 18% for six months due to unfavorable foreign currency translation and a 5% decline in organic revenue for both periods, reflecting weak economic conditions as well as lower new business.

·Europe, Middle East & Africa revenue decreased 15% and 13% for the quarter and six months, respectively, reflecting unfavorable foreign currency translation. Organic revenue declined 3% for the quarter and 1% for six months reflecting weak economic conditions in continental Europe and slower growth in emerging markets.

·Asia Pacific revenue declined 16% for the quarter and 18% for six months, driven by unfavorable foreign currency translation and a 1% organic decline for both periods, reflecting the impact from exiting certain businesses in Japan, economic weakness in Asia, and political unrest in Thailand partially offset by strong growth in New Zealand and modest growth in Australia.

·Reinsurance revenue increased 50% for the quarter and 52% for six months due to the impact of the Benfield merger in fourth quarter 2008, Gallagher Re acquisition in first quarter 2008 and organic revenue growth.  Organic growth for the quarter and six months was 4% and 2%, respectively, driven primarily by growth in global treaty placements and a

43

slight hardening of markets.

Income from Continuing Operations Before Income Taxes

Second quarter 2009 income from continuing operations before income taxes decreased $24 million to $210 million while six months 2009 income from continuing operations before income taxes was $538 million, a $61 million increase.  In 2009, the quarterly pretax margin in this segment was 13.3%, down 120 basis points from 14.5% in 2008. On a year-to-date basis the pretax margin was 17.2%, up 220 basis points from 15.0% in 2008.  Contributing to the decreased margins and pretax income for the quarter are:

·$43 million in higher restructuring costs,

·$30 million lower investment income,

·$16 million impact of unfavorable foreign exchange rates, and

·higher amortization costs related to the Benfield intangible assets.

These declines were partially offset by:

·$10 million in lower costs related to anti-corruption and compliance initiatives,

·restructuring savings, and

·lower E&O expenditures.

Contributing to the six months increased margins and pretax income were:

·a $54 million gain from the pension curtailments,

·$23 million in lower costs related to anti-corruption and compliance initiatives,

·the inclusion of Benfield results, and

·restructuring savings.

These improvements were partially offset by:

·$51 million of lower investment income,

·$35 million impact of unfavorable foreign exchange rates,

·$25 million of higher restructuring costs,

·a $5 million gain in 2008 related to the sale of land, and

·higher intangible amortization costs related to Benfield.

Consulting

Aon Consulting is one of the world’s largest integrated human capital consulting organizations.  Our Consulting segment:

·provides a broad range of consulting services and outsourcing, and

·generated 16% of Aon’s total operating segment revenue for both second quarter and six months 2009.

Beginning in late 2008, the disruption in the global credit markets and the deterioration of the financial markets created significant uncertainty in the marketplace.  A severe and/or prolonged economic downturn could hurt our clients’ financial condition and the levels of business activities in the industries and geographies where we operate.  While we believe that the majority of our practices are well positioned to manage through this time, these challenges may reduce demand for some of our services or depress pricing of those services and have an adverse effect on our new business and results of operations.

·Consulting Services’ commissions, fees and other revenue decreased $27 million or 10% and $52 million or 9% on a quarterly and year-to-date basis, respectively, due to unfavorable foreign currency translation.  Organic revenue declined by 1% for second quarter and there was organic revenue growth of 1% for six months 2009, respectively.  The quarterly decline was driven mainly by declines in our human capital and compensation consulting practices, partially offset by modest growth in health and benefits consulting.  The year-to-date growth was driven by our health and benefits consulting, offset by lower revenue in our compensation consulting practice.

45

·Outsourcing revenue decreased $8 million or 14% and $17 million or 15% on a quarterly and year-to-date basis, respectively, due to unfavorable foreign currency translation and a 4% decline in organic revenue for both periods.  The organic revenue decline reflects the previously announced termination of our contract with AT&T, partially offset by modest growth in benefits outsourcing.

Income from Continuing Operations Before Income Taxes

Second quarter 2009 pretax income from continuing operations decreased 5% to $41 million.  However, the pretax margin increased 90 basis points from 12.8% in 2008 to 13.7% in 2009.  The decline in revenue for the quarter was mostly offset by savings related to the 2007 restructuring plan and declines across most expense categories. The small decline in pretax income from continuing operations, despite the 11% decrease in revenue, drove the improved margins.  On a year-to-date basis, 2009 pretax income from continuing operations increased $5 million or 5% to $111 million.  The six month pretax income from continuing operations improvement was principally driven by the $20 million gain from the pension curtailment, along with savings related to the 2007 restructuring plan and declines across most expense categories, which more than offset the 10% decline in revenue.  Higher pretax income from continuing operations, plus lower revenue, drove the increase in pretax margin from 15.6% in 2008 to 18.2% in 2009.

Unallocated Income and Expense

A reconciliation of segment income before income taxes to income from continuing operations before income taxes follows (in millions):

	Three months ended						Six months ended
	June 30,						June 30,
	2009			2008			2009			2008
Segment income from continuing operations before income taxes	$	251		$	277		$	649		$	583
Unallocated investment income and other revenue	13			17			14			22
Unallocated expenses	(28		)	(37		)	(55		)	(57		)
Interest expense	(26		)	(31		)	(55		)	(64		)
Income from continuing operations before income taxes	$	210		$	226		$	553		$	484

Unallocated investment income and other revenue consists primarily of revenue from our equity ownership in insurance investments and income associated with invested assets not directly required to support the risk and insurance brokerage services and consulting businesses.

Unallocated investment income and other revenue was $13 million for second quarter 2009, a decrease of $4 million from 2008.  For the six month period, unallocated investment income and other revenue was $14 million, a decrease of $8 million from 2008.  For both periods, the decrease was driven by lower investment income, partially offset by revenue associated with our Juniperus/JCHL investment.  The decline in investment income was primarily attributable to lower interest rates and investment balances.

Unallocated expenses include corporate governance costs not allocated to the operating segments, and the costs associated with our ownership of insurance investments. These expenses decreased to $28 million in second quarter 2009 from $37 million last year.  For the six month period, unallocated expenses decreased to $55 million from $57 million in 2008.  For both periods the decline was mainly due to a $5 million gain from the extinguishment of $15 million of junior subordinated debentures and lower compensation related expenses, and was partially offset by additional expense associated with our ownership in insurance investments.

Interest expense, which represents the cost of our worldwide debt obligations, decreased $5 million in the second quarter and $9 million on a year-to-date basis compared to last year, primarily due to lower interest rates and the favorable impact of foreign currency.

FINANCIAL CONDITION AND LIQUIDITY

Cash Flows

Cash flows from operating activities

Cash flows from operating activities were $97 million for the six months ended June 30, 2009 compared to $268 million for the six months ended June 30, 2008. Noncash adjustments totaled $122 million in 2009 and $1.2 billion in 2008, and included the following:

·Pretax gains from disposal of businesses were $94 million in 2009 and $1.4 billion in 2008. 2009 activity was due principally to the sale of our AIS business, which resulted in an $86 million gain. The sale of our CICA and Sterling businesses resulted in gains totaling $1.4 billion during 2008.

46

·Amortization of intangible assets was $45 million in 2009 compared to $25 million in 2008. The increase in amortization reflects the additional intangible assets associated with the merger with Benfield in the fourth quarter of 2008.

·Stock compensation expense was $95 million in 2009 and $142 million in 2008. The decrease between years was due primarily to an acceleration of expense in 2008 due to modification of stock awards and options in connection with the sale of CICA, a reduction of expense in 2009 related to performance-based incentives and a change in forfeiture estimates related to a system conversion.

Changes in operating assets and liabilities reduced cash by $465 million for the six months ended June 30, 2009, but increased cash by $125 million for the six months ended June 30, 2008.

·In our Risk and Insurance Brokerage Services segment, we typically hold funds on behalf of clients as a result of premiums received from clients and claims due to clients that are in transit to insurers. These funds held on behalf of clients are generally invested in interest bearing premium trust accounts and can fluctuate significantly depending on when we collect cash from our clients and when premiums are remitted to the insurance carriers. Aon earns interest in these accounts; however, the principal is segregated and not available for general operating expenses. During 2009, the net change in the premium trust accounts was $113 million, while in 2008, the net change was $300 million.

·Net receivables reflect changes in brokerage commission and fees, consulting work in progress, premium finance notes and other items, representing an increase in operating cash flow of $138 million and $43 million for 2009 and 2008, respectively. These types of receivables fluctuate based on when invoices are billed and cash collected.

·Reductions in accounts payable and accrued liabilities negatively impacted operating cash flows by $305 million and $350 million for 2009 and 2008, respectively, primarily reflecting the payment of incentive compensation to our employees in the first quarter of both years.

47

·Cash contributions to our major defined pension plans exceeded pension expense by $242 million in 2009. The large cash contributions are primarily driven by new funding agreements for our U.K. pension plans, completed during second quarter 2009. Pension contributions for 2009 and 2008 were $298 million and $104 million, respectively. In 2009, we plan to contribute $419 million in total to our major defined pension plans.

·Other assets and liabilities used $166 million in 2009, while contributing $166 million in 2008. The difference between years was driven by a significant tax expense recognized in the first half of 2008 from the sale of CICA and Sterling, where the tax payment was not made until later in the year, as well as an advance payment associated with a sponsorship agreement in 2009.

Cash flows from investing activities

Cash provided by investing activities was $47 million for 2009, compared to $1.1 billion in 2008. In 2009, we received $138 million in cash from the sale of operations, which was primarily our AIS subsidiary. In 2008, the sale of our CICA and Sterling businesses generated substantially all of the $2.9 billion of proceeds from the sale of operations. We spent $40 million in 2009 for acquisitions, which were primarily for international retail businesses. In 2008, net purchases of investments were $1.7 billion, principally reflecting the investment from the proceeds of the CICA and Sterling sales.

Cash flows from financing activities

Our financing activities used $150 million of cash in 2009. Treasury stock transactions-net reflects the purchase of $125 million of treasury shares, less the proceeds from the exercise of stock options. We used a net $31 million to pay down our outstanding debt. Cash dividends to shareholders used $83 million. In 2008, we used $1.5 billion for financing activities. This was primarily composed of $1.5 billion of share repurchase activity, less the proceeds from the exercise of stock options, the net repayment of debt of $165 million, and dividends of $89 million.

48

Financial Condition

Since year-end 2008, net assets, representing total assets minus total liabilities, increased $593 million to $6.0 billion. Working capital, excluding assets and liabilities held-for-sale, decreased $681 million to $951 million, due primarily to an increase in short-term debt, partially offset by lower accounts payable and accrued liabilities.

·Short-term debt increased $576 million due to the reclassification of the Euro credit facility balance of $677 million from long-term debt in the second quarter of 2009.  This reclassification was done in anticipation of paying the balance with the proceeds from the issuance of €500 million, 6.25% senior unsecured debentures due July 1, 2014, which were issued on July 1, 2009.  The Euro Credit facility balance was repaid in July 2009.  This increase was partially offset by the payment of $100 million in debt related to a VIE for which we were the primary beneficiary.

·Accounts payable and accrued liabilities decreased $168 million due primarily to the payment of incentive compensation in the first quarter.

·Goodwill increased $246 million due principally to the impact of foreign currency translation.

·Long-term debt decreased by $623 million, principally reflecting the reclassification of our Euro facility balance to short-term debt.

·Pension and other post employment liabilities declined $391 million, driven by a remeasurement of the U.S. defined benefit pension plan as of January 31, 2009, as well as contributions made to our various plans during the first six months of 2009.

In our capacity as an insurance broker or agent, we collect premiums from insureds and, after deducting our commission, remit the premiums to the respective insurance underwriter.  We also collect claims or refunds from underwriters on behalf of insureds.  Unremitted insurance premiums and claims are held by us in a fiduciary capacity. The levels of fiduciary assets and liabilities can fluctuate significantly, depending on when we collect the premiums, claims and refunds, make payments to underwriters and insureds, and foreign currency movements. Fiduciary assets, because of their nature, are required to be invested in very liquid securities with highly-rated, credit-worthy financial institutions.

In our condensed consolidated statements of financial position, the amount we report for fiduciary assets and fiduciary liabilities are equal.  Our fiduciary assets include cash and investments of $3.7 billion and $3.2 billion at June 30, 2009 and December 31, 2008, respectively, and fiduciary receivables of $8.6 billion and $7.5 billion at June 30, 2009 and December 31, 2008, respectively.

As disclosed in Note 15 to our condensed consolidated financial statements, the majority of our investments carried at fair value are money market funds whose fair values are categorized as Level 2. Money market funds are carried at cost as an approximation of fair value. Based on market convention, we consider cost a practical and expedient measure of fair value. These money market funds are held throughout the world with various financial institutions. We do not believe that there are any market liquidity issues affecting the fair value of these investments.

As of June 30, 2009, our investments in money market funds and highly liquid debt securities had a fair value of $2.7 billion and are classified as cash equivalents, short-term investments or fiduciary assets in the consolidated statements of financial condition depending on their nature and initial maturity.

49

The following table summarizes our fiduciary assets and non-fiduciary cash and investments as of June 30, 2009 (in millions):

	Balance Sheet Classification

We did not hold any investments categorized as Level 1 during 2009.

Our investments categorized as Level 3 are valued using internally developed models with unobservable inputs and represent a small portion of our portfolio.

Borrowings

Total debt at June 30, 2009 was $1,930 million, a decrease of $47 million from December 31, 2008, reflecting lower foreign borrowings as well as a redemption and cancellation of a portion of our 8.205% Debentures (see below), partially offset by the impact of foreign exchange rates.  Our total debt as a percentage of total capital was 24.3% and 26.7% at June 30, 2009 and December 31, 2008, respectively.

In 1997, we created Aon Capital A, a wholly-owned statutory business trust (“Trust”), for the purpose of issuing mandatorily redeemable preferred capital securities (“Capital Securities.’“). We received cash and an investment in 100% of the common equity of Aon Capital A by issuing 8.205% Junior Subordinated Deferrable Interest Debentures (the “Debentures”) to Aon Capital A. These transactions were structured such that the net cash flows from Aon to Aon Capital A matched the cash flows from Aon Capital A to the third party investors. We determined that we were not the primary beneficiary of Aon Capital A, a VIE, and, thus reflected the Debentures as long-term debt.

During the first half of 2009, we repurchased $15 million face value of the Capital Securities for approximately $10 million, resulting in a $5 million gain reflected in other (income) expense in the condensed consolidated statement of income.

To facilitate the legal release of the obligation created through the Debentures associated with this repurchase and future repurchases, we dissolved the Trust effective June 25, 2009. This dissolution resulted in the exchange of the Capital Securities held by third parties for the Debentures. Also in connection with the dissolution of the Trust, the $24 million of common equity of Aon Capital A held by us was exchanged for $24 million of Debentures, which were then cancelled.

Following these actions, $687 million of Debentures remain outstanding as of June 30, 2009. The Debentures are subject to mandatory redemption on January 1, 2027 or are redeemable in whole, but not in part, at our option upon the occurrence of certain events.

50

At June 30, 2009, we had a $600 million U.S. bank credit facility, which expires in February 2010, to support commercial paper and other short-term borrowings.  The facility allows us to issue up to $150 million in letters of credit.  At June 30, 2009, we have issued $20 million in letters of credit.

We also have foreign credit facilities available.  At June 30, 2009, we had available to us:

·a five-year €650 million ($914 million at June 30, 2009 exchange rates) multi-currency facility of which $677 million was outstanding at June 30, 2009.  See Note 10 to the consolidated financial statements in our 2008 Form 10-K for further discussion of both the U.S. and Euro facilities, and

·a 364-day €25 million ($35 million) facility.

On July 1, 2009, one of our indirectly wholly-owned subsidiaries issued €500 million ($703 million at June 30, 2009 exchange rates) of 6.25% senior unsecured debentures due on July 1, 2014.  The principal and interest on the debentures is unconditionally and irrevocable guaranteed by us.  Most of the net proceeds from the offering were used to repay our $677 million outstanding indebtedness under our Euro credit facility.

The major rating agencies’ ratings of our debt at August 6, 2009 appear in the table below.

	Ratings
	Senior Long-term Debt	Commercial Paper	Outlook
Standard & Poor’s	BBB+	A-2	Stable
Moody’s Investor Services	Baa2	P-2	Stable
Fitch, Inc.	BBB+	F-2	Stable

There were no changes in our ratings or outlook during the quarter.

A downgrade in the credit ratings of our senior debt and commercial paper would:

·increase our borrowing costs and reduce our financial flexibility, and

·increase our commercial paper interest rates or possibly restrict our access to the commercial paper market altogether.  Although we have committed backup lines, we cannot ensure that our financial position will not be hurt if we can no longer access the commercial paper market.

Equity

Equity increased $593 million from December 31, 2008 to $6,008 million, driven primarily by our 2009 net income of $440 million and a decrease in our accumulated other comprehensive loss, partially offset by share repurchases of $125 million in the second quarter of 2009.

Accumulated other comprehensive loss attributable to our stockholders decreased $208 million since December 31, 2008.  Compared to year end 2008:

·net foreign currency translation increased by $139 million attributable to the weakening of the U.S. dollar against foreign currencies,

·net unrealized investment gains declined $9 million,

·net derivative gains increased $18 million, and

·our net post-retirement benefit obligation decreased by $60 million, reflecting a remeasurement of the U.S. qualified defined benefit plan associated with the decision to cease crediting future benefits relating to salary and service period.

Variable Interest Entities

Globe Re Limited (“Globe Re”) is a limited-life reinsurance vehicle. In June 2008, Globe Re entered into a reinsurance agreement with a third party reinsurance company, whereby Globe Re provides reinsurance coverage for a defined portfolio of property catastrophe reinsurance contracts underwritten by the third party.  The reinsurance coverage is for a one-year period, which ended June 1, 2009. Globe Re is deemed to be a VIE since the equity investors at risk lack a controlling financial interest.  Aon owns an 85% equity economic interest in Globe Re, is deemed to be the primary beneficiary and consolidates Globe Re. In connection with the winding up of its operations, during June 2009 Globe Re repaid its $100 million of short-term debt from available cash.  In early July 2009, Aon’s equity investment in Globe Re was repaid.  Globe Re will be fully liquidated in third quarter 2009.  At June 30, 2009, Globe Re had assets of $56 million and liabilities of $2 million.

Juniperus Insurance Opportunity Fund Limited (“Juniperus”), a VIE, is an investment vehicle that invests in an actively managed and diversified portfolio of insurance risks. In 2008, a subsidiary of Aon acquired a 76% equity interest in the Juniperus’ Class A shares.  The equity interest has been reduced to 40% at June 30, 2009.  Also in 2008, Juniperus Capital Holdings Limited (“JCHL”) was formed to provide investment management and related services to Juniperus.  Aon currently has 73% of the economic and voting interest of JCHL.  Based on Aon’s interest in Juniperus, it is subject to a majority of the expected residual returns and losses.  Similarly, Aon’s equity and economic interest in JCHL would cause it to absorb a majority of JCHL’s expected losses.  Therefore, Aon is considered the primary beneficiary of both companies, and as such these entities have been consolidated.  At June 30, 2009, Juniperus and JCHL together had assets of $175 million and liabilities of $35 million.  For Juniperus, if a disaster such as wind, earthquakes or other named catastrophe occurs, we could lose some or all of our investment, which is approximately $63 million at June 30, 2009.  Our investment represents a $58 million equity investment and a $5 million loan.

Restructuring Initiatives

Aon Benfield Restructuring Plan

In 2008, we announced a global restructuring plan (“Aon Benfield Plan”) in conjunction with our merger with Benfield.  The restructuring plan is intended to integrate and streamline operations across the combined Aon Benfield organization.  The Aon Benfield Plan includes an estimated 500 to 700 job eliminations.   As of June 30, 2009, approximately 400 jobs have been eliminated under the Plan.  Additionally, duplicate space and assets will be abandoned.  We recorded $21 million and $30 million of restructuring and related expenses in the second quarter and six months 2009, respectively. We estimate that this plan will result in cumulative costs totaling approximately $185 million over a three-year period, of which $104 million was recorded in conjunction with the Benfield merger and is included as part of the Benfield purchase price allocation, and $81 million of which will result in charges to earnings.  All costs associated with the Aon Benfield Plan are included in the Risk and Insurance Brokerage Services segment.  Charges related to the restructuring are included in compensation and benefits, other general expenses, and depreciation and amortization in the accompanying condensed consolidated statements of income.  The Company expects the restructuring activities and related expenses to affect continuing operations into 2011.

The restructuring plan, before any potential reinvestment of savings, is expected to deliver cumulative cost savings of approximately $33-41 million in 2009, $84-94 million in 2010 and $122 million in 2011.  We realized approximately $10 million and $14 million of cost savings in the second quarter and six months of 2009, respectively.  All of the components of the restructuring plan are not finalized and actual savings, total costs and timing may vary from those estimated due to changes in the scope, underlying assumptions of the plan, and to foreign exchange rates.

52

The following is a summary of the restructuring and related expenses by type and estimated to be incurred through the end of the restructuring initiative related to the merger and integration of Benfield (in millions):

	Actual
	Purchase Price Allocation		Second Quarter 2009		Six Months 2009		Total to Date		Estmated Total Cost for Restructuring Period (1)
Workforce reduction	$	74	$	17	$	25	$	99	$	126
Lease consolidation	28		4		4		32		48
Asset impairments	—		—		1		1		8
Other costs associated with restructuring (2)	2		—		—		2		3
Total restructuring and related expenses	$	104	$	21	$	30	$	134	$	185

(1)Actual costs, when incurred, will vary due to changes in the assumptions built into this plan.  Significant assumptions likely to change when plans are finalized and approved include, but are not limited to, changes in severance calculations, changes in the assumptions underlying sublease loss calculations due to changing market conditions, and changes in the overall analysis that might cause the Company to add or cancel componentinitiatives.

(2)Other costs associated with restructuring initiatives, including moving costs, consulting fees and legal fees, arerecognized when incurred.

2007 Restructuring Plan

In 2007, we announced a global restructuring plan intended to create a more streamlined organization and reduce future expense growth to better serve clients (“2007 Plan”).  The three-year plan has evolved as new opportunities have been identified and existing initiatives have been finalized. We estimate that the 2007 Plan will result in cumulative pretax charges totaling approximately $550 million. Expenses will include workforce reduction and lease consolidation costs, asset impairments, as well as other expenses necessary to implement the restructuring initiative. To date, we have recorded approximately $405 million of restructuring and related expenses, with $74 million and $53 million recorded in the second quarter of 2009 and 2008, respectively and $108 million and $113 million recorded in six months 2009 and 2008, respectively.  We expect the remaining restructuring and related expenses to affect operations through the end of 2009.  We realized approximately $52 million and $93 million of cost savings in the second quarter and six months 2009, respectively.  We anticipate that these initiatives will lead to annualized cost-savings, before any potential reinvestment of savings, of approximately $240-$265 million in 2009, and $370 million by 2010.  However, there can be no assurances that we will achieve the targeted savings.

The 2007 Plan includes an estimated 3,900 job eliminations.  Through June 30, 2009, approximately 2,300 job eliminations have occurred.  We also expect to close or consolidate several offices resulting in sublease losses or lease buy-outs.  Costs related to the restructuring are included in compensation and benefits, other general expenses and depreciation and amortization in the accompanying condensed consolidated statements of income.

Total restructuring and related expenses	$	46	$	251	$	74	$	108	$	405	$	550

(1)Actual costs, when incurred, will vary due to changes in the assumptions built into this plan.  Significant assumptions likely to change when plans are finalized and approved include, but are not limited to, changes in severance calculations, changes in the assumptions underlying sublease loss calculations due to changing market conditions, and changes in the overall analysis that might cause the Company to add or cancel componentinitiatives.

(2)Other costs associated with restructuring initiatives, including moving costs, consulting fees and legal fees, arerecognized when incurred.

Workforce reductions reflect a cash expense, though we may recognize the expense before paying for the expenditure.  Asset impairments are non-cash expenses.  Lease consolidation accruals reflect the present value of future cash flows.  Other costs are cash expenses, which are expensed in the period in which they are incurred.

The following table summarizes actual restructuring and related expenses incurred and estimated to be incurred through the end of the restructuring initiative, by segment (in millions):

	Actual

Off Balance Sheet Arrangements

We record various contractual obligations as liabilities in our consolidated financial statements.  While we do not recognize other items as liabilities in the financial statements, such as certain purchase commitments and other executory contracts, we are required to disclose them.

Aon and its subsidiaries:

·have issued letters of credit to cover contingent payments for taxes and other business obligations to third parties,

·accrue amounts in our consolidated financial statements for these letters of credit to the extent they are probable and estimable, and

·use SPEs and QSPEs, also known as special purpose vehicles, in some of our operations, following the relevant accounting guidance.

54

Reinsurance Guarantee

In connection with the AWG transaction, we issued an indemnification that protects the purchaser from credit exposure relating to the property and casualty reserves that have been reinsured.  These reinsurance recoverables amount to $597 million at June 30, 2009.  Trust balances and letters of credit offsetting these reinsurance recoverables total approximately $118 million.  At both June 30, 2009 and December 31, 2008, we had recorded a $9 million liability, reflecting the fair value of this indemnification.

The liability represents the present value of the indemnification on the credit risk of the reinsurers.  With the sale of the remaining P&C insurance underwriting operations, which we expect to be completed in the third quarter of 2009, the buyer will assume the indemnification with respect to reinsurance recoverables.

Premium Financing Operations

Some of our U.S., U.K., Canadian, and Australian subsidiaries have originated short-term loans (generally with terms of 12 months or less) to businesses to finance their insurance premium obligations, and then have sold these premium finance agreements in securitization transactions that meet the criteria for sale accounting.  In December 2008, we signed a definitive agreement to sell our U.S. operations of the premium finance business (Cananwill).  In connection with our sale of the U.S. premium finance business, we have guaranteed the collection of the principal amount of the premium finance notes sold to the buyer, which, at June 30, 2009, was $170 million, if losses exceed the historical credit loss reserve for the business.  Historical losses in this business have been very low since the premium finance notes are generally fully collateralized by the lender’s right, in the event of non-payment, to cancel the underlying insurance contract and collect the unearned premium from the insurance carrier.  We do not expect to incur any significant losses related to this guarantee.  This disposition was completed in February 2009. 

In the U.K., premium finance agreements have been sold to special purpose entities (“SPEs”), which are considered QSPEs. The QSPEs fund their purchases of premium finance agreements by selling undivided beneficial interests in the agreements to Bank SPEs. In Canada and Australia, undivided interests in the premium finance agreements have been sold directly to Bank SPEs.  The Bank SPEs are variable interest entities.

The QSPEs used in the U.K. are not consolidated in our financial statements because the criteria for sale accounting have been met.

For the Canadian and Australian sales, we determined that non-consolidation of the Bank SPEs is appropriate because we are not their primary beneficiary.

Our variable interest in the Bank SPEs in these jurisdictions is limited to our retained interests in premium finance agreements sold to the Bank SPEs.  We review all material off-balance sheet transactions annually or whenever a reconsideration event occurs for the continued propriety of our accounting.

The total amount that can be advanced by the Bank SPEs on premium finance agreements sold to them at any one time is limited by the sale agreements, the limit was $267 million at June 30, 2009.  The outstanding balance of sold portfolio at June 30, 2009 was $247 million, and the Bank SPEs had advanced $194 million. The outstanding balance of sold portfolios at December 31, 2008 was $1.1 billion, and the Bank SPEs had advanced $981 million.

We record gains on the sale of premium finance agreements.  When we calculate the gain, we include all costs we expect to incur for the relevant Bank SPEs.  The gains, which are included in commissions, fees and other revenue in the condensed consolidated statements of income, were $8 million and $15 million for the three months ended June 30, 2009 and 2008, respectively, and $14 million and $32 million for the six months ended June 30, 2009 and 2008, respectively.

·We record our retained interest in the sold premium finance agreements at fair value, and report it in receivables in the condensed consolidated statements of financial position.  We estimate fair value by discounting estimated future cash flows using discount rates that are commensurate with the underlying risk, expected future prepayment rates, and credit loss estimates.

·We also retain servicing rights for sold agreements, and earn servicing fee income over the servicing period.  Because the servicing fees represent adequate compensation for the servicing of the receivables, we have not recorded any servicing assets or liabilities.

The third-party bank sponsors or other participants in the Bank SPEs provide the liquidity support and bear the credit risks on the receivables, subject to limited recourse, in the form of over-collateralization provided by us (and other sellers) as required by the sales agreements.  The over-collateralization of our sold receivables represents our maximum exposure to credit-related losses, and was approximately $61 million at June 30, 2009.  We continually review our retained interest in the sold portfolio, taking into consideration credit loss trends in the sold portfolio, conditions in the credit markets and other factors, and adjust its carrying value accordingly.

With the exception of our Australian sales agreements, all of our other sales agreements require us to meet the following covenants:

·consolidated net worth, as defined, of at least $2.5 billion,

·consolidated EBITDA (earnings before interest, taxes, depreciation and amortization) to consolidated net interest of at least 4 to 1, and

·consolidated indebtedness to consolidated EBITDA of no more than 3 to 1.

We renewed the Canadian and U.K. sales agreements in the fourth quarter of 2008 and the Australian sales agreement in the second quarter of 2009.  The current environment in the credit markets influenced the renewal process, the renewed terms are more restrictive, and the over-collateralization requirements were increased.

In June and July of 2009, we entered into agreements with third parties with respect to our premium finance businesses in the U.K., Canada and Australia (collectively, the “Cananwill International Agreements”).  As a result of the Cananwill International Agreements the third parties will begin originating, financing and servicing premium finance loans generated by referrals from our brokerage operations.  We expect to cease financing and servicing premium finance loans by the end of the fourth quarter of 2009.  The third parties did not acquire the existing portfolio of our premium finance loans, as such we did not extend any guarantees under these agreements.

PEPS I

In 2001, we sold the vast majority of our LP portfolio, valued at $450 million, to PEPS I, a QSPE.  The common stock interest in PEPS I is held by a limited liability company owned by us (49%) and by a charitable trust, which we do not control (51%).  We do not include PEPS I’s assets and liabilities and operations in our consolidated financial statements.

56

In 2001, PEPS I sold approximately $171 million of investment grade fixed-maturity securities to unaffiliated third parties.  PEPS I then paid our insurance underwriting subsidiaries the $171 million in cash and issued them an additional $279 million in fixed-maturity and preferred stock securities.

As part of this transaction, we are required to purchase additional fixed-maturity securities from PEPS I in an amount equal to the unfunded LP commitments as they are requested.  These fixed-maturity securities are rated below investment grade.  Commitments of $1 million were funded by us in the second quarter and six months of 2009.  As of June 30, 2009, unfunded commitments amounted to $41 million.  These commitments have specific expiration dates, and the general partners may decide not to draw on these commitments.

We received $1 million in income distributions from our preferred investment in PEPS I in the second quarter 2009.  We did not receive any income distributions in second quarter 2008.  We received $1 million and $2 million in distributions in the first six months of 2009 and 2008, respectively.  Any distributions are included in investment income.  Whether we receive additional preferred returns will depend on the performance of the LP interests underlying PEPS I, which we expect to vary from period to period.  We do not control the timing of the distributions.

We derive the estimated fair value of our $91 million preferred stock investments in PEPS I primarily from valuations received from the general partners of the LP interests held by PEPS I.

Contractual Obligations

During the quarter ended June 30, 2009, we entered into a sponsorship agreement and various information technology contracts. The timing of payments under these obligations is:

·	remainder of 2009	–   $4 million
·	2010-2011	–   $56 million
·	2012-2013	–   $51 million
·	2014 and beyond	–   $4 million

CRITICAL ACCOUNTING POLICIES

There have been no changes in our critical accounting policies, which include restructuring, pensions, contingencies, intangible assets, share-based payments, income taxes and policy liabilities, as discussed in our 2008 Annual Report on Form 10-K.

INFORMATION CONCERNING FORWARD-LOOKING STATEMENTS

This report contains 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. 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, changes in global equity and fixed income markets that could affect the return on invested assets, fluctuations in exchange and interest rates that could influence revenue and expense, rating agency actions that could affect our ability to borrow funds, funding of our various pension plans, changes in the competitive environment, our ability to implement restructuring initiatives and other initiatives intended to yield cost savings, changes in commercial property and casualty markets and commercial premium rates that could impact revenues, the outcome of inquiries from regulators and investigations related to compliance with the U.S. Foreign Corrupt Practices Act and non-U.S. anti-corruption laws, the impact of investigations brought by U.S. state attorneys general, U.S. state insurance regulators, U.S. federal prosecutors, U.S. federal regulators, and regulatory authorities in the U.K. and other countries, the impact of class actions and individual lawsuits including client class actions, securities class actions, derivative actions and ERISA class actions, the cost of resolution of other contingent liabilities and loss contingencies, our ability to integrate Benfield successfully and to realize the anticipated benefits of the Benfield merger.

We undertake no obligation to publicly update forward-looking statements, whether as a result of new information, future events or otherwise.

57

ITEM 3.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to potential fluctuations in earnings, cash flows and the fair value of certain of our assets and liabilities due to changes in interest and foreign exchange rates.  To manage the risk from these exposures, we enter into a variety of derivative instruments.  We do not enter into derivatives or financial instruments for trading purposes.

We are subject to foreign exchange rate risk from translating the financial statements of our foreign subsidiaries into U.S. dollars. Our primary exposures are to the British pound, the Euro, the Canadian dollar, and the Australian dollar.  We use over-the-counter (“OTC”) options and forward contracts to reduce the impact of foreign currency fluctuations on the translation of our foreign operations’ financial statements.

Additionally, some of our foreign brokerage subsidiaries receive revenues in currencies that differ from their functional currencies.  Our U.K. subsidiary earns a portion of its revenue in U.S. dollars and Euros but most of its expenses are incurred in pounds sterling.  Our policy is to convert into pounds sterling sufficient U.S. dollar and Euro revenue to fund the subsidiary’s pound sterling expenses using OTC options and forward exchange contracts.  At June 30, 2009, we have hedged approximately 52% and 33% of our U.K. subsidiaries’ expected U.S. dollar and Euro transaction exposures for the next twelve months, respectively.  We do not generally hedge these exposures beyond three years.

The translated value of revenue and expense from our international brokerage operations are subject to fluctuations in foreign exchange rates.  Second quarter and six months 2009 diluted earnings per share were negatively impacted by $0.03 and $0.05, respectively, related to translation losses.

We also use forward contracts to offset foreign exchange risk associated with foreign denominated inter-company notes.

Our businesses’ income is affected by changes in international and domestic short-term interest rates.  We monitor our net exposure to short-term interest rates and, as appropriate, hedge our exposure with various derivative financial instruments.  This activity primarily relates to brokerage funds held on behalf of clients in the U.S. and on the continent of Europe.  A decrease in global short-term interest rates adversely affects our income.

58

ITEM 4.   CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures.  Based on Aon management’s evaluation (with the participation of the chief executive officer and chief financial officer), as of the end of the period covered by this report, Aon’s chief executive officer and chief financial officer have concluded that the disclosure controls and procedures (as defined in Rules 13a-15(e) and 15(d) —15(e) under the Securities Exchange Act of 1934, as amended, (the “Exchange Act”)) are effective to ensure that information required to be disclosed by Aon in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms.

Changes in internal control over financial reporting.  In November, 2008, the Company acquired Benfield Group Limited and its subsidiaries (“Benfield”).  As a result, we have expanded our internal controls over financial reporting to include the Benfield operations. Integration of Benfield’s operations, along with the related internal controls, into Aon’s organization is expected to continue throughout 2009 and 2010.  Future material changes to internal controls, if applicable, will be disclosed in accordance with SEC requirements.  Other than the changes above, no other changes in Aon’s internal control over financial reporting occurred during second quarter 2009 that have materially affected, or are reasonably likely to materially affect, Aon’s internal control over financial reporting.

Exhibit 10.1

Thirteenth Amendment to the

2002 Restatement of Aon Savings Plan

WHEREAS, the Aon Savings Plan (the “Plan”) is currently set out in the 2002 Restatement of the Aon Savings Plan, which was generally effective as of January 1, 2002, as amended from time to time thereafter (the “Restatement”).

WHEREAS, Section 17.01 of the Plan allows the Board of Directors of Aon Corporation to amend the Plan, and the Board has delegated to the undersigned officers of Aon Corporation the authority to make certain amendments to the Plan.

WHEREAS, the undersigned officers desire to amend the Plan as set forth herein.

NOW, THEREFORE, the Plan, as set out in the Restatement and as amended from time to time, is further amended as follows, effective as of April 1, 2009, unless otherwise specified below:

1.             A new Section 26.09 is hereby added to the Plan as follows:

“Section 26.09       Benfield Retirement Plan

Effective April 1, 2009 (the “Merger Date”), the vast majority of assets and liabilities of the Benfield Retirement Plan (the “Benfield Plan”) will be transferred to this Plan. Effective as soon thereafter as administratively feasible, the liquidation proceeds under the Reserve Primary Fund in the Self-Managed Brokerage Accounts of the Benfield Plan will be transferred to this Plan and invested in accordance with the participants’ investment elections directing employee contributions then in effect. In general, the rules and provisions of this Plan will apply to the transferred accounts; however, the following special provisions apply effective January 1, 2009, or such later date determined by the Committee, to an Employee who was employed by Benfield Holdings, Inc. or its subsidiaries or affiliates (“Benfield”) on November 28, 2008 (“Legacy Benfield Employee”), the date of the amalgamation (“Amalgamation Date”) involving Aon Corporation, Aon Benfield (Bermuda) Ltd., and Benfield Group Limited:

(a)Participation.  A Legacy Benfield Employee will become a participant in this Plan on January 1, 2009 and be enrolled with the same savings elections as in effect under the Benfield Plan as of December 31, 2008. Otherwise, a Legacy Benfield Employee will become a participant in this Plan upon satisfaction of the requirements of Section 2.  Notwithstanding the foregoing, any Legacy Benfield Employee who is not a participant in the Benfield Plan on December 31, 2008 will be subject to this Plan’s automatic enrollment in accordance with Section 2.03 of this Plan effective upon the mailing of the Eligible Automatic Contribution Arrangement notice via First Class U.S. Mail on January 14, 2009.  The Legacy Benfield Employee will have a 30-day window to opt out of this Plan or change his or her savings election.

1

(b)Credit for service for eligibility. For purposes of satisfying Section 2 (relating to service requirements for eligibility), a Legacy Benfield Employee will receive credit for periods of Service with Benfield prior to the Amalgamation Date.  In addition, with respect to any individual who terminated employment with Benfield before the Amalgamation Date, but is employed by the Company before incurring five consecutive One-Year Breaks-In-Service, Service for Benfield will be considered Service for the Company.

(c)Vesting.  Pursuant to the Benfield Plan, the account of each Legacy Benfield Employee became 100% vested on the Amalgamation Date. Notwithstanding the foregoing, Legacy Benfield Employees will be subject to the vesting provisions of this Plan for Employer Contributions made pursuant to Section 3 hereof.  For purposes of satisfying Section 5.02 of this Plan (relating to Service requirements for vesting), service for Benfield will be considered Service for the Company.  In addition, with respect to any individual who is a Legacy Benfield Employee who terminated employment with Benfield before the Amalgamation Date, but is employed by the Company before incurring five consecutive One-Year Breaks-In-Service, service for Benfield will be considered Service for the Company.  In the case of an individual who terminated employment with Benfield prior to the Amalgamation Date and subsequently incurred five consecutive One-Year Breaks-In-Service, Service after such Breaks-In-Service will not be taken into account for the purpose of determining such Participant’s non-forfeitable interest in such Participant’s Accounts.  Finally, for purposes of determining the Years of Participation under Section 13.01 for the Legacy Benfield Employees or any other Benfield Plan participant with a Transferred Balance, the rules regarding the calculation of Years of Service under the Benfield Plan will be used.

(d)Valuation of Transferred Balance.  The balance as of the market close on March 31, 2009 in the account of the Benfield Plan for each Participant who was a participant in such plan on such date will constitute the transferred balance to the account under this Plan of such Participant as of April 1, 2009.

(e)Separate Accounting.  Gains, losses, withdrawals, contributions, forfeitures and other credits or charges attributable to benefits accrued by Participants under the terms of the Benfield Plan as of March 31, 2009 will be accounted for separately.  The provisions covering the accounts of the Aon Savings Plan will apply after March 31, 2009 except to the extent that prior plan provisions must be maintained due to requirements of ERISA Section 411(d)(6).

(f)Investment Election.  If a Legacy Benfield Employee does not make an investment election under this Plan prior to the normal close of the New

2

York Stock Exchange on March 31, 2009, his or her transferred balance from the Benfield Plan will be invested in accordance with this Plan’s default investment procedures. The investment election, default or affirmative, shall be the same as that which directs employee contributions, whether or not the participant is currently eligible to make such contributions.

(g)Beneficiary Designations.  If a Legacy Benfield Employee became a Participant in this Plan on January 1, 2009, executed a new beneficiary designation under the Plan on or before April 1, 2009, and had executed a prior beneficiary designation which was effective under the Benfield Plan, the prior beneficiary designation became invalid effective April 1, 2009. If a Participant in the Benfield Retirement Plan executed a prior Beneficiary designation which was effective under the Benfield Plan and does not execute a new beneficiary designation after March 31, 2009, the prior beneficiary designation remains valid until a new designation is executed.  If no beneficiary designation has been submitted by a Legacy Benfield Employee, the default designation will be governed by the provisions of this Plan.

(h)Self-Managed “Brokerage” Account.  If a Legacy Benfield Employee had maintained a Self-Managed Account (“SMA”), a brokerage window, under the Benfield Plan, such account shall be transferred to the Self-Directed Investment Account (“SDIA) described in Section 7.07 of this Plan, “in-kind”, upon direction by the participant prior to the transfer of the investments. If the participant does not provide affirmative direction, the investments in the SMA shall be liquidated at prevailing market prices as soon as administratively feasible by the Trustee and transferred to the Plan’s Investment Funds in accordance with the participant’s investment elections or in accordance with this Plan’s default investment procedures in the absence of an affirmative election. The investment election shall be the same as that which directs employee contributions.”

2.             The remaining provisions of the Plan are unchanged.

IN WITNESS WHEREOF, Aon Corporation has adopted this Thirteenth Amendment to the 2002 Restatement of the Aon Savings Plan, effective as of April 1, 2009.

Exhibit 10.2

AMENDED AND RESTATED EMPLOYMENT AGREEMENT

This Employment Agreement (this “Agreement”) is dated as of June 10, 2009 (the “Effective Date”) between Aon Corporation, a Delaware corporation (the “Company”) and Ted T. Devine (the “Executive”).

WHEREAS, the Company seeks to employ Executive as Executive Vice President of Aon Corporation and Chief Executive Officer of Aon Specialty; and

WHEREAS, Executive desires to continue to serve and be employed upon the terms and subject to the conditions as amended and restated herein.

NOW, THEREFORE, in consideration of the premises and the mutual agreements contained herein, the parties hereby agree as follows:

1.Employment.    The Company hereby agrees to employ the Executive and the Executive hereby agrees to be employed upon the terms and subject to the conditions contained in this Agreement.  The term of employment of the Executive commenced on May 2, 2005 (the “Employment Date”) and will continue pursuant to this Agreement until April 30, 2013, unless earlier terminated pursuant to Section 4 hereof (the “Employment Period”).

2.Position and Duties; Responsibilities; Board Service.   (a)    Position and Duties. The Company shall employ the Executive during the Employment Period as Executive Vice President of Aon Corporation and Chief Executive Officer of Aon Specialty, or in another Level 1A senior executive capacity with profit and loss responsibility as may be authorized or directed by the Chief Executive Officer of the Company (the “CEO”).  During the Employment Period, the Executive shall perform faithfully and loyally and to the best of his abilities the duties assigned to him hereunder and shall devote his full business time, attention and effort to the affairs of the Company and its subsidiaries and shall use his best efforts to promote the interests of the Company and its subsidiaries.  The Executive may engage in charitable, civic or community activities and, with the prior approval of the CEO, may serve as a director of any other business corporation, provided that (i) such activities or service do not interfere with his duties hereunder or violate the terms of any of the covenants contained in Section 6, 7, or 8 hereof and (ii) such other business corporation provides the Executive with director and officer insurance coverage which, in the opinion of the CEO, is adequate under the circumstances.

(b)Responsibilities.  The Executive will have the authority and responsibility typically held by an Executive Vice President of a large, global publicly-traded company.  The Executive will also perform such other duties (not inconsistent with his positions) on behalf of the Company and its subsidiaries as may be from time to time authorized or directed by the CEO.  The Executive will report to the CEO.

3.Compensation.    (a) Base Salary.  The Company will pay the Executive a base salary of $950,000 per annum (“Base Salary”), payable semi-monthly in accordance with the Company’s executive payroll policy.  Such Base Salary shall be reviewed annually on the Company’s regular executive salary review schedule, and shall be subject to adjustment at the discretion of the CEO and Organization and Compensation Committee of the Board of Directors.

(b)Annual Bonus.  During the Employment Period, the Executive’s annual bonus target will be 150% of his Base Salary in effect at the end of the year, and the maximum annual bonus payable will be three times such target.  Except as set forth herein, the Executive’s bonus shall be subject to the terms of the Company’s shareholder-approved Senior Officer Incentive Compensation Plan and to the Aon Incentive Stock Program, as those plans and programs may be amended from time to time.

(c)Initial Stock Award.  On the Employment Date, the Executive received a restricted stock unit award of 100,000 shares of common stock of the Company.  Except as otherwise set forth herein, such restricted stock units are subject to terms and conditions generally applicable to restricted stock unit grants under the Aon Stock Incentive Plan (the “Incentive Plan”).  In the event of termination of the Executive’s employment by the Company without Cause pursuant to Section 4(d) hereof such award shall continue to vest in accordance with its full original vesting schedule.

(d)Initial Stock Option.  (i) On the Employment Date, the Executive was granted a non-qualified option of 150,000 shares of the common stock of the Company.  The non-qualified stock option was granted pursuant to and, except as otherwise set forth herein, is subject to, the terms of the Incentive Plan.  Such options shall vest in accordance with the terms generally applicable to option grants under the Aon Stock Incentive Plan.  In the event of termination of the Executive’s employment by the Company without Cause pursuant to Section 4(d) hereof such option shall continue to vest in accordance with its full original vesting schedules.

(e)Other Benefits.  During the Employment Period, the Executive shall be entitled to participate in the Company’s employee benefit plans generally available to executives of the Company (such benefits being hereinafter referred to as the “Employee Benefits”).  The Executive also shall be entitled to vacation (not less than 4 weeks per year) or illness in accordance with the Company’s policy for executives and to receive all other fringe benefits as are from time to time made generally available to executives of the Company.

(f)Expense Reimbursement.  During the Employment Period, the Company shall reimburse the Executive in accordance with the Company’s policies and procedures, for all proper expenses incurred by him in the performance of his duties hereunder.

(g)2009 Award.  On or about April 27, 2009, the Executive received an award of 25,000 restricted stock units of Aon Corporation common stock under the Incentive Plan, as amended from time to time (the “2009 Award”).  The restricted stock units were granted in accordance with the approval provided by the Organization and Compensation Committee of Aon Corporation’s board of directors on January 29, 2009.  Except as otherwise set forth herein, the award is subject to the Company’s standard terms and provisions, including vesting provisions.  For the avoidance of doubt, the restricted stock units will vest in equal installments of 25% on the second through fifth anniversary of the date of grant subject to the Executive’s continued employment.

(h)Other Equity Awards.  Subsequent to the Employment Date and in addition to the 2009 Award, the Executive has received additional equity awards that except as otherwise set forth herein are governed by the terms of the applicable award documents and by the Incentive Plan.

2

death.  The Company shall pay to the Executive’s executor or administrator of Executive’s estate a lump sum cash amount equal to the Executive’s Base Salary at the rate in effect at the date of such death, to which the Executive would have been entitled from the date of such death until the end of the Employment Period, reduced by the amount of any benefit paid under any individual or group life insurance policy maintained by the Company for the benefit of the Executive.

(b)Disability.  The Company may, at its option, terminate this Agreement upon written notice to the Executive if the Executive, because of physical or mental incapacity or disability, fails to perform the essential functions of his position, with reasonable accommodation, if relevant, required of him hereunder for a continuous period of 120 days or any 180 days within any 12-month period.  Upon such termination, the Executive or his legal representative shall be entitled to receive the Base Salary which shall have accrued to the date of termination, plus continuation of Base Salary, at the rate in effect at the date of such termination of employment, until the end of the Employment Period; provided, however, that the amount of any benefit payable under any disability insurance policy maintained by the Company for the benefit of the Executive shall be deducted from the payments of such Base Salary.  In the event of any dispute regarding the existence of the Executive’s incapacity or disability hereunder, the matter shall be resolved by the determination of an independent physician agreed to between the Executive and the Company specializing in the claimed area of incapacity or disability.  The Executive shall submit to appropriate medical examinations for purposes of such determination.

(c)Cause.  (i) The Company may at any time, at its option, terminate the Executive’s employment under this Agreement immediately for Cause (as hereinafter defined).  The Company’s decision in this regard shall be taken by the Governance Committee of the Board (“Governance Committee”).  The Executive shall be given at least seven days advance written notice of any meeting at which the Governance Committee proposes to put forward for a vote a decision on whether or not to terminate the Executive for Cause and the written notice shall describe in reasonable detail the basis on which the Governance Committee may conclude that Cause exists.  The Executive shall have the opportunity to appear in person and to make such written and/or oral presentation to such meeting of the Governance Committee as the Executive thinks fit.  If a majority of the Governance/Nominating Committee authorizes by affirmative vote a termination for Cause at such meeting (whether or not the Executive makes any oral or written presentations at such meeting) such determination shall be final and binding upon the Company and the Executive once such decision is confirmed in writing and communicated to the Executive.

(ii)As used in this Agreement, the term “Cause” shall mean any one or more of the following:

(A)  any intentional act of fraud, embezzlement or theft by the Executive in connection with his duties hereunder or in the course of his employment hereunder or the Executive’s admission or conviction of, or plea of nolo contendere to, a felony or of any crime involving moral turpitude, fraud, embezzlement, theft or misrepresentation;

(B)  any gross negligence or willful misconduct of the Executive resulting in a loss to the Company or any of its subsidiaries, or damage to the reputation of the Company or any of its subsidiaries;

3

(C)  any breach by the Executive of any one or more of the covenants contained in Section 6, 7, or 8 hereof;

(D)  any violation of any statutory or common law duty of loyalty to the Company or any of its subsidiaries;

(E)  the determination by Gregory Case, in his capacity as CEO, that the Executive has breached the policies or procedures of the Company or engaged in any action or behavior that is, or if allowed to continue could be, detrimental to the business or reputation of the Company; or

(F)  the Executive’s receipt of two written disciplinary notices from the Global Head of Human Resources within any twenty-four (24) month period as a result of the Executive’s breach of the policies or procedures of the Company or any action or behavior by the Executive that is, or if allowed to continue could be, detrimental to the business or reputation of the Company.

(iii)The exercise of the right of the Company to terminate this Agreement pursuant to this Section 4(c) shall not abrogate the rights or remedies of the Company in respect of the breach giving rise to such termination.

(iv)If the Company terminates the Executive’s employment for Cause, as defined in Section 4(c), he shall be entitled to:

(A) accrued Base Salary through the date of the termination of his employment; and

(B) other Employee Benefits to which the Executive is entitled upon his termination of employment with the Company, including any regular and supplemental retirement and disability benefits required pursuant to the terms of the plans and programs of the Company.

(v)The definition of “Cause” herein shall replace any other definitions of “Cause” in any prior agreements between the Executive and the Company, including, but not limited to, any prior equity awards, and such definition shall be used for purposes of determining the Executive’s right to any payments or benefits under such prior agreements in the event of his termination of employment.

(d)Termination Without Cause.  If, during the Employment Period, the Company terminates the employment of the Executive hereunder for any reason other than a reason set forth in Section 4(a), (b) or (c), the Company will give the Executive 12 months’ prior written notice of such termination and:

(i)during the notice period or thereafter, as applicable, the Executive will be entitled to the payments and benefits specified by Sections 4(c)(iv)(A) and (B); and

(ii)concurrent with the last day of the notice period, the Executive will be entitled to receive a lump sum cash payment.  The lump sum payment will be equal to the product of (x) two

4

and (y) the sum of the annual Base Salary and the Executive’s target annual incentive bonus for the Bonus Year in which the Executive’s employment terminates.

Notwithstanding the foregoing provisions of this Section 4(d), if any payment specified by this Section 4(d) would not be deductible by the Company for federal income tax purposes by reason of Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”), or any similar or successor statute (excluding Section 280G of the Code), such payment will be deferred and the amount thereof (plus earnings thereon in accordance with the terms of such deferral) will be paid to the Executive at the earliest time that such payment is deductible by the Company.

(e)Voluntary Termination.   The Executive may voluntarily terminate his employment with the Company prior to the end of the Employment Period for any reason.  If the Executive voluntarily terminates his employment pursuant to this Section 4(e), the Executive shall give the Company 12 months prior written notice and shall be entitled to the payments specified by Sections  4(c)(iv)(A) and(B).

(f)  Termination for Good Reason.  (i) Upon 30 days’ prior written notice to the Company, the Executive may voluntarily terminate his employment for Good Reason (as herein defined).  If the Executive voluntarily terminates employment pursuant to this Section 4(f), the Executive’s entitlement to compensation and benefits will cease immediately, except that the Executive will be entitled to the payments and benefits specified in Section 4(d);

(ii)As used in this Agreement, “Good Reason” means, during the Employment Period and without the written consent of the Executive, the following, provided that an isolated, insubstantial or inadvertent action not taken in bad faith or a failure not occurring in bad faith, which is reasonably remedied by the Company promptly after receipt of notice thereof given by the Executive will not constitute Good Reason:

(B)any failure by the Company to comply with the provisions of Section 3 hereof;

(C)any requirement by the Company that the Executive’s principal office be located more than 50 miles outside of the greater Chicago metropolitan area; or

(D)any other material breach by the Company of this Agreement.

(iii)The Executive acknowledges and agrees that the performance of his duties in London in connection with his position as Chief Executive Officer of Aon Specialty and any travel connected with such duties will not be considered to give rise to a Good Reason for his termination under this Agreement.

5.Federal and State Withholding.The Company shall deduct from the amounts payable to the Executive pursuant to this Agreement the amount of all required federal, state and local withholding taxes in accordance with the Executive’s Form W-4 on file with the Company, and all applicable federal employment taxes.

(c)Nonsolicitation.  The Executive further agrees that during the Noncompetition Period he shall not in any manner, directly or indirectly, induce or attempt to induce any employee of the Company or any of its subsidiaries to terminate or abandon his or her employment for any purpose whatsoever.

(d)Exceptions.  Nothing in this Section 6 shall prohibit the Executive from being (i) a stockholder in a mutual fund or a diversified investment company or (ii) a passive owner of not more than two percent of the outstanding stock of any class of a corporation, any securities of which are publicly traded, so long as Executive has no active participation in the business of such corporation.

(e)Reformation.  If, at any time of enforcement of this Section 6, a court holds that the restrictions stated herein are unreasonable under circumstances then existing, the parties hereto agree that the maximum period, scope or geographical area reasonable under such circumstances shall be substituted for the stated period, scope or area and that the court shall be allowed to revise the restrictions contained herein to cover the maximum period, scope and area permitted by law.  This Agreement shall not authorize a court to increase or broaden any of the restrictions in this Section 6.

(f)Consideration; Breach.  The Company and the Executive agree that the payments to be made, and the benefits to be provided, by the Company to the Executive pursuant to Section 3 hereof shall be made and provided in consideration of the Executive’s agreements contained in Section 6 hereof.  In the event that the Executive shall commit a material breach of any provision of Section 6 hereof, the Company shall be entitled immediately to terminate making all remaining payments and providing all remaining benefits pursuant to Section 3 hereof and upon such termination the Company shall have no further liability to the Executive under this Agreement.

12.Severability.  Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of any other provision of this Agreement or the validity, legality or enforceability of such provision in any other jurisdiction, but this Agreement shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

13.Entire Agreement.  This Agreement and any existing equity awards referenced herein constitute the entire agreement and understanding between the parties with respect to the subject matter hereof, and this Agreement supersedes and preempts any prior understandings, agreements or representations by or between the parties, written or oral, which may be related in any manner to the subject matter hereof.

15.No Mitigation.   In no event shall the Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under any of the provisions of this Agreement, and such amounts shall not be reduced whether or not the Executive obtains other employment.

17.Headings; Inconsistency.  Section headings in this Agreement are included herein for convenience of reference only and shall not constitute a part of this Agreement for any other purpose.  In the event of any inconsistency between the terms of this Agreement and any form, award, plan or policy of the Company or any other agreement between the Executive and the Company, the terms of this Agreement shall control.

19.Amendment and Waiver.  The provisions of this Agreement may be amended or waived only by the written agreement of the Company and the Executive, and no course of conduct

8

or failure or delay in enforcing the provisions of this Agreement shall affect the validity, binding effect or enforceability of this Agreement.

20.Counterparts.   This Agreement may be executed in two counterparts, each of which shall be deemed to be an original an both of which together shall constitute one and the same instrument.

21.Code Section 409A.  (a)  The time or schedule of any payment or amount scheduled to be paid pursuant to the terms of this Agreement, including but not limited to any restricted stock unit or other equity-based award, payment, or amount that provides for the “deferral of compensation” (as such term is described under Section 409A of the Internal Revenue Code of 1986, as amended (“Code Section 409A”)), may not be accelerated except as otherwise permitted under Code Section 409A and the guidance and Treasury regulations issued thereunder.

(b)  The parties intend that this Agreement and the benefits provided hereunder be interpreted and construed to comply with Code Section 409A to the extent applicable thereto.  The time and form of payment of incentive compensation, disability benefits, severance payments, expense reimbursements and payments of in-kind benefits described herein will be made in accordance with the applicable sections of this Agreement, provided that with respect to termination of employment for reasons other than death, the payment at such time can be characterized as a “short-term deferral” for purposes of Code Section 409A or as otherwise exempt from the provisions of Code Section 409A, or if any portion of the payment cannot be so characterized, and the Executive is a “specified employee” under Code Section 409A, such portion of the payment will be delayed until the earlier to occur of the Executive’s death or the date that is six months and one day following the Executive’s termination of employment (the “Delay Period”).  Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this section will be paid or reimbursed to the Executive in a lump sum, and any remaining payments due under this Agreement will be payable at the same time and in the same form as such amounts would have been paid.  Further, if the Executive is a “specified employee” and if any equity-based awards granted to the Executive by the Company pursuant to this Agreement or otherwise, continue to vest upon the Executive’s termination of employment, and are deemed a “deferral of compensation” (as such term is described under Code Section 409A), the equity-based awards will not be settled or released until the expiration of the Delay Period.  For purposes of applying the provisions of Code Section 409A, each separately identifiable amount to which the Executive is entitled will be treated as a separate payment.  In addition, the disability benefits and severance payments will be treated as a series of separate payments.

(c)  Although the Company intends to administer the Agreement so that it will comply with the requirements of Code Section 409A, the Company does not represent or warrant that the Agreement will comply with Code Section 409A or any other provision of federal, state, local or non-United States law.  Provided that the Company administers this Agreement in a manner consistent with the terms of this Agreement, neither the Company, its subsidiaries, nor their respective directors, officers, employees or advisers will be liable to the Executive (or any other individual claiming a benefit through the Executive) for any tax, interest, or penalties the Executive may owe as a result of compensation paid under the Agreement, and the Company and its subsidiaries will have no obligation to indemnify or otherwise protect the Executive from the obligation to pay any taxes pursuant to Code Section 409A.

9

22.Mediation.  In the event a dispute arises in connection with this Agreement, the Company and the Executive agree to submit the dispute to non-binding mediation to be paid for by the Company which shall select the mediator.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the date first written above.
