Financial Results

The following is a summary of our 2022 financial results:



•Revenue increased $286 million, or 2%, to $12.5 billion in 2022 compared to
2021, reflecting 6% organic revenue growth and a 1% favorable impact from
fiduciary investment income, partially offset by a 4% unfavorable impact from
foreign currency translation a 1% unfavorable impact from acquisitions,
divestitures and other.

•Operating expenses decreased $1.3 billion, or 13%, to $8.8 billion in 2022
compared to 2021 due primarily to the $1.0 billion payment made in connection
with terminating the combination with WTW (the "Termination Fee") and certain
transaction costs incurred related to the termination in the prior year
(together, the "Transaction Costs") and a $373 million favorable impact from
foreign currency translation, partially offset by an increase in expense
associated with 6% organic revenue growth, investments in long-term growth, and
a $58 million charge related to certain legal settlements reached.

•Operating margin increased to 29.4% in 2022 from 17.1% in 2021. The increase was driven by a decrease in operating expenses as listed above and organic revenue growth of 6%.

•Due to the factors set forth above, Net income was $2.6 billion in 2022, an increase of $1.3 billion, or 102%, from 2021.

•Diluted earnings per share increased 119% to $12.14 per share during the twelve months of 2022 compared to $5.55 per share for the prior year period.



•Cash flows provided by operating activities was $3.2 billion in 2022, an
increase of $1.0 billion, or 48%, from $2.2 billion in 2021, primarily due to
the Transaction Costs paid in the prior year period, and strong operating income
growth, partially offset by higher incentive compensation payments made in the
current year following strong performance in 2021.

We focus on four key metrics not presented in accordance with U.S. GAAP that we
communicate to shareholders: organic revenue growth, adjusted operating margin,
adjusted diluted earnings per share, and free cash flow. These non-GAAP metrics
should be viewed in addition to, not instead of, our Consolidated Financial
Statements. The following is our measure of performance against these four
metrics for 2022:

•Organic revenue growth, a non-GAAP measure defined under the caption "Review of
Consolidated Results - Organic Revenue Growth," was 6% in 2022, compared to 9%
organic growth in the prior year.

•Adjusted operating margin, a non-GAAP measure defined under the caption "Review
of Consolidated Results - Adjusted Operating Margin," was 30.8% in 2022,
compared to 30.1% in the prior year. The increase in adjusted operating margin
primarily reflects 6% organic revenue growth and a higher fiduciary investment
income, partially offset by increased expenses and investments in long-term
growth.

•Adjusted diluted earnings per share, a non-GAAP measure defined under the
caption "Review of Consolidated Results - Adjusted Diluted Earnings per Share,"
was $13.39 per share in 2022, an increase of $1.39 per share, or 12%, from
$12.00 per share in 2021. The increase in adjusted diluted earnings per share
primarily reflects strong operational performance and effective capital
management, highlighted by $3.2 billion of share repurchase during 2022,
partially offset by an unfavorable impact from foreign currency translation.

•Free cash flow, a non-GAAP measure defined under the caption "Review of
Consolidated Results - Free Cash Flow," was $3.0 billion in 2022, an increase of
$978 million, or 48%, from $2.0 billion in 2021, reflecting an increase in Cash
flows from operations, partially offset by a $59 million increase in capital
expenditures.

ENVIRONMENTAL, SOCIAL, AND GOVERNANCE



For many companies, the management of ESG risks and opportunities has become
increasingly important, and ESG-related challenges, such as extreme weather
events, supply chain disruptions, cyber events, regulatory changes, ongoing
public health impacts, and the increased focus on workforce resilience in highly
varied work environments continue to create volatility and uncertainty for our
clients. Aon offers a wide range of risk assessment, consulting and advisory
solutions, many of which are significant parts of our core business offerings,
designed to address and manage ESG issues for clients, and to enable our clients
to create more sustainable value. We view ESG risks as presenting an important
opportunity for Aon to work together as one firm to address client needs and
improve our impact on ESG matters.

Consolidated Results for 2022 Compared to 2021

Revenue



Total revenue increased $286 million, or 2%, to $12.5 billion in 2022, compared
to $12.2 billion in 2021. The increase was driven by 6% organic revenue growth
and a 1% favorable impact from fiduciary investment income, partially offset by
a 4% unfavorable impact from foreign currency translation and a 1% unfavorable
impact from acquisitions, divestitures, and other.

Commercial Risk Solutions revenue increased $80 million, or 1%, to $6.7 billion
in 2022, compared to $6.6 billion in 2021. Organic revenue growth was 6% in
2022, reflecting growth across every major geography, including double-digit
growth in Latin America, Asia, and the Pacific, driven by strong net new
business generation, retention, and management of the renewal book portfolio.
U.S. retail brokerage was pressured primarily by Transaction Solutions, which
declined due to lower external deal volume. Results also reflect strong growth
globally in the affinity business across both consumer and business solutions,
including growth in the travel and events practice and Digital Client Solutions.
On average globally, exposures and pricing were modestly positive, resulting in
modestly positive market impact.

Reinsurance Solutions revenue increased $193 million, or 10%, to $2.2 billion in
2022, compared to $2.0 billion in 2021. Organic revenue growth was 8% in 2022
driven by strong net new business generation in treaty, as well as solid growth
in facultative placements and the Strategy and Technology Group. In addition,
market impact was modestly positive on results.

Health Solutions revenue increased $70 million, or 3%, to $2.2 billion in 2022,
compared to $2.2 billion in 2021. Organic revenue growth was 8% in 2022,
reflecting growth globally in core health and benefits brokerage, driven by
strong retention, net new business generation and management of the renewal book
portfolio. Strength in health and benefits included growth in advisory work
related to wellbeing and resilience. Results also reflect double-digit growth in
Human Capital, driven by data and advisory solutions, and modest growth in
Consumer Benefits Solutions.

Wealth Solutions revenue decreased $59 million, or 4%, to $1.4 billion in 2022,
compared to $1.4 billion in 2021. The decrease was primarily driven by a 5%
unfavorable impact from foreign currency translation and a 2% unfavorable impact
from acquisitions, divestitures, and other. This decrease was offset by organic
revenue growth of 3% in 2022 driven by high demand and project related work
related to pension risk transfer and ongoing impacts of regulatory changes. In
Investments, a decrease in AUM-based delegated investment management revenue due
to equity market and interest rate movements was partially offset by higher
advisory demand and project-related work.

Compensation and Benefits



Compensation and benefits decreased $261 million, or 4%, in 2022 compared to
2021. The decrease was primarily driven by a $293 million favorable impact from
foreign currency translation and a $245 million decrease in Transaction Costs,
partially offset by an increase in expense associated with 6% organic revenue
growth.

Information Technology

Information technology, which represents costs associated with supporting and
maintaining our infrastructure, increased $32 million, or 7%, in 2022 compared
to 2021. The increase was primarily driven by ongoing investments in Aon
Business Services-enabled technology platforms and technology to drive long-term
growth, partially offset by a $17 million decrease in Transaction Costs.

Premises



Premises, which represents the cost of occupying offices in various locations
throughout the world, decreased $38 million, or 12%, in 2022 compared to 2021.
The decrease was primarily driven by a $22 million decrease in Transaction Costs
and a $19 million favorable impact from foreign currency translation.

Depreciation of Fixed Assets



Depreciation of fixed assets primarily relates to software, leasehold
improvements, furniture, fixtures and equipment, computer equipment, buildings,
and automobiles. Depreciation of fixed assets decreased $28 million, or 16%, in
2022 compared to 2021. The decrease was primarily driven by a $16 million
decrease in Transaction Costs.

Amortization and Impairment of Intangible Assets



Amortization and impairment of intangibles primarily relates to finite-lived
customer-related and contract-based, technology, and tradename assets.
Amortization and impairment of intangibles decreased $34 million, or 23%, in
2022 compared to 2021.

                                       32
--------------------------------------------------------------------------------

Other General Expenses



Other general expenses decreased $964 million, or 43%, in 2022 compared to 2021.
The decrease was primarily driven by a $1.1 billion decrease in Transaction
Costs, partially offset by an increase in expense associated with 6% organic
revenue growth, including travel and entertainment expense, and a $58 million
charge from certain legal settlements reach in 2022.

Interest Income



Interest income represents income earned on operating cash balances and other
income-producing investments. It does not include interest earned on Funds held
on behalf of clients. Interest income was $18 million in 2022, an increase of $7
million, or 64%, from 2021.

Interest Expense

Interest expense, which represents the cost of our debt obligations, was $406
million in 2022, an increase of $84 million, or 26%, from 2021. The increase
primarily reflects an increase in total debt.

Other Income (Expense)

Other expense was $125 million in 2022, which primarily reflects a non-cash pension settlement charge of $170 million incurred in the fourth quarter, compared to Other income of $152 million in 2021, primarily reflecting a gain from sale of businesses in the prior year period.

Income before Income Taxes

Income before income taxes was $3.2 billion in 2022, a 63% increase from $1.9 billion in 2021. The increase was primarily driven by $1.4 billion in Transaction Costs in the prior year period and strong operational performance.

Income Taxes



The effective tax rate on net income was 16.2% in 2022 and 32.3% in 2021. The
2022 tax rate was primarily driven by the geographical distribution of income
and certain discrete items, primarily the favorable impacts of share-based
payments.

The 2021 tax rate was primarily driven by the impact of the Termination Fee, the
U.K. statutory tax rate increase, and the tax benefit of share-based payments.
The U.K. enacted legislation in the second quarter of 2021 which increases the
corporate income tax rate from 19% to 25% with effect from April 1, 2023 and the
Company remeasured its U.K. deferred tax assets and liabilities accordingly.

Net Income Attributable to Aon Shareholders

Net income attributable to Aon shareholders increased to $2.6 billion, or $12.14 per diluted share, in 2022, compared to $1.3 billion, or $5.55 per diluted share, in 2021.

Consolidated Results for 2021 Compared to 2020



We have elected not to include a discussion of our consolidated results for 2021
compared to 2020 in this report in reliance upon Instruction 1 to Item 303(b) of
Regulation S-K. This discussion can be found in our Annual Report on Form 10-K
for the year ended December 31, 2021, which was filed with the SEC on February
18, 2022.

Non-GAAP Metrics

In our discussion of consolidated results, we sometimes refer to certain
non-GAAP supplemental information derived from consolidated financial
information specifically related to organic revenue growth, adjusted operating
margin, adjusted diluted earnings per share, adjusted net income attributable to
Aon shareholders, adjusted net income per share, other income (expense), as
adjusted, adjusted effective tax rate, free cash flow, and the impact of foreign
exchange rate fluctuations on operating results. Management believes that these
measures are important to make meaningful period-to-period comparisons and that
this supplemental information is helpful to investors. Management also uses
these measures to assess operating performance and performance for compensation.
This non-GAAP supplemental information should be viewed in addition to, not
instead of, our Consolidated Financial Statements.

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

Organic Revenue Growth



We use supplemental information related to organic revenue growth to help us and
our investors evaluate business growth from existing operations. Organic revenue
growth is a non-GAAP measure that includes the impact of certain intercompany
activity and excludes the impact of changes in foreign exchange rates, fiduciary
investment income, acquisitions, divestitures, transfers between revenue lines,
and gains or losses on derivatives accounted for as hedges. This supplemental
information related to organic revenue growth represents a measure not in
accordance with U.S. GAAP and should be viewed in addition to, not instead of,
our Consolidated Financial Statements. Industry peers provide similar
supplemental information about their revenue performance, although they may not
make identical adjustments. A reconciliation of this non-GAAP measure to the
reported Total revenue is as follows (in millions, except percentages):

Adjusted Operating Margin



We use adjusted operating margin as a non-GAAP measure of core operating
performance of the Company. Adjusted operating margin excludes the impact of
certain items, as listed below, because management does not believe these
expenses reflect our core operating performance. This supplemental information
related to adjusted operating margin represents a measure not in accordance with
U.S. GAAP, and should be viewed in addition to, not instead of, our Consolidated
Financial Statements.

A reconciliation of this non-GAAP measure to reported operating margins is as follows (in millions, except percentages):

of which were terminated, as well as certain compensation expenses and expenses
related to further steps on our Aon United operating model as a result of the
termination. Additionally, this includes the $1 billion Termination Fee paid in
connection with the termination of the combination.

Adjusted Diluted Earnings per Share



We use adjusted diluted earnings per share as a non-GAAP measure of our core
operating performance. Adjusted diluted earnings per share excludes the impact
of certain items, as listed below, because management does not believe these
expenses are the best indicators of our core operating performance. This
supplemental information related to adjusted diluted earnings per share

Free Cash Flow



We use free cash flow, defined as cash flow provided by operations minus capital
expenditures, as a non-GAAP measure of our core operating performance and cash
generating capabilities of our business operations. This supplemental
information related to free cash flow represents a measure not in accordance
with U.S. GAAP and should be viewed in addition to, not instead of, the
Consolidated Financial Statements. The use of this non-GAAP measure does not
imply or represent the residual cash flow for discretionary expenditures. A
reconciliation of this non-GAAP measure to cash flow provided by operations is
as follows (in millions):

Impact of Foreign Currency Exchange Rate Fluctuations



Because we conduct business in more than 120 countries and sovereignties,
foreign currency exchange rate fluctuations have a significant impact on our
business. Foreign currency exchange rate movements may be significant and may
distort true period-to-period comparisons of changes in revenue or pretax
income. Therefore, to give financial statement users meaningful information
about our operations, we have provided an illustration of the impact of foreign
currency exchange rate fluctuations on our financial results. The methodology
used to calculate this impact isolates the impact of the change in currencies
between periods by translating the prior year's revenue, expenses, and net
income using the current year's foreign currency exchange rates.

Currency fluctuations had an unfavorable impact of $0.33 on earnings per diluted
share during the year ended December 31, 2022 if prior year period results were
translated at current period foreign exchange rates. Currency fluctuations had a
favorable impact of $0.17 on earnings per diluted share during the year ended
December 31, 2021, if 2020 results were translated at 2021 rates.

Currency fluctuations had an unfavorable impact of $0.44 on adjusted earnings
per diluted share during the year ended December 31, 2022 if prior year period
results were translated at current period foreign exchange rates. Currency
fluctuations had a favorable impact of $0.23 on adjusted earnings per diluted
share during the year ended December 31, 2021, if 2020 results were translated
at 2021 rates. These translations are performed for comparative and illustrative
purposes only and do not impact the accounting policies or practices for amounts
included in our Financial Statements.

LIQUIDITY AND FINANCIAL CONDITION

Liquidity

Executive Summary



We believe that our balance sheet and strong cash flow provide us with adequate
liquidity. Our primary sources of liquidity in the near-term include cash flows
provided by operations and available cash reserves; primary sources of liquidity
in the long-term include cash flows provided by operations, debt capacity
available under our credit facilities, and capital markets. Our primary uses of
liquidity are operating expenses and investments, capital expenditures,
acquisitions, share repurchases, pension obligations, and shareholder dividends.
We believe that cash flows from operations, available credit facilities,
available cash reserves, and the capital markets will be sufficient to meet our
liquidity needs, including principal and interest payments on debt obligations,
capital expenditures, pension contributions, and anticipated working capital
requirements in the next twelve months and over the long-term.

Cash on our balance sheet includes funds available for general corporate
purposes, as well as amounts restricted as to their use. Funds held on behalf of
clients in a fiduciary capacity are segregated and shown together with
uncollected insurance premiums and claims in Fiduciary assets in the
Consolidated Statements of Financial Position, with a corresponding amount in
Fiduciary liabilities.

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 underwriters. We also collect claims or refunds from
underwriters on behalf of insureds, which are then returned to the insureds.
Unremitted insurance premiums and claims are held by us in a fiduciary capacity.
The levels of funds held on behalf of clients and liabilities can fluctuate
significantly depending on when we collect the premiums, claims, and refunds,
make payments to underwriters and insureds, and collect funds from clients and
make

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

payments on their behalf, and upon the impact of foreign currency movements.
Funds held on behalf of clients, because of their nature, are generally invested
in very liquid securities with highly rated, credit-worthy financial
institutions. Fiduciary assets include funds held on behalf of clients comprised
of cash and cash equivalents of $6.4 billion and $6.1 billion at December 31,
2022 and 2021, and fiduciary receivables of $9.5 billion and $8.3 billion at
December 31, 2022 and 2021, respectively. While we earn investment income on the
funds held in cash and money market funds, the funds cannot be used for general
corporate purposes.

We maintain multi-currency cash pools with third-party banks in which various
Aon entities participate. Individual Aon entities are permitted to overdraw on
their individual accounts provided the overall global balance does not fall
below zero. At December 31, 2022, non-U.S. cash balances of one or more entities
may have been negative; however, the overall balance was positive.

Operating Activities

Net cash provided by operating activities during the year ended December 31,
2022 increased $1,037 million, or 48%, from the prior year to $3,219
million. This amount represents Net income reported, generally adjusted for the
following primary drivers including gains from sales of businesses, losses from
sales of businesses, share-based compensation expense, depreciation expense,
amortization and impairments, and other non-cash income and expenses, including
pension settlement charges. Adjustments also include changes in working capital
that relate primarily to the timing of payments of accounts payable and accrued
liabilities and collection of receivables.

Pension Contributions



Pension contributions were $59 million for the year ended December 31, 2022, as
compared to $87 million for the year ended December 31, 2021. In 2023, we expect
to contribute approximately $61 million in cash to our pension plans, including
contributions to non-U.S. pension plans, which are subject to changes in foreign
exchange rates.

Investing Activities

Cash flows used for investing activities during the year ended December 31, 2022
were $449 million, a decrease of $498 million compared to prior year. Generally,
the primary drivers of cash flows used for investing activities are acquisition
of businesses, purchases of short-term investments, capital expenditures, and
payments for investments. Generally, the primary drivers of cash flows provided
by investing activities are sales of businesses, sales of short-term
investments, and proceeds from investments. The gains and losses corresponding
to cash flows provided by proceeds from investments and used for payments for
investments are primarily recognized in Other income (expense) in the
Consolidated Statements of Income.

Short-term Investments



Short-term investments increased $160 million at December 31, 2022 as compared
to December 31, 2021. As disclosed in Note 14 "Fair Value Measurements and
Financial Instruments" of the Notes to Consolidated Financial Statements
contained in Part II, Item 8 of this report, the majority of our investments
carried at fair value are money market funds. These money market funds are held
throughout the world with various financial institutions. We are not aware of
any market liquidity issues that would materially impact the fair value of these
investments.

Acquisitions and Dispositions of Businesses



During 2022, the Company completed the acquisition of five businesses for
consideration of $162 million, net of cash and funds held on behalf of clients,
and the disposition of three businesses for a $81 million cash inflow, net of
cash and funds held on behalf of clients.

During 2021, the Company completed the acquisition of two businesses for
consideration of $14 million, net of cash and funds held on behalf of clients,
and the disposition of six business for a $218 million cash inflow, net of cash
and funds held on behalf of clients.

Capital Expenditures



The Company's additions to fixed assets, including capitalized software, which
amounted to $196 million in 2022 and $137 million in 2021, primarily related to
refurbishing and modernizing of office facilities, software development costs,
and computer equipment purchases.

Financing Activities



Cash flows used for financing activities during the year ended December 31, 2022
was $1,790 million, a decrease of $134 million compared to prior year.
Generally, the primary drivers of cash flow used for financing activities are
repayments of debt, share repurchases, dividends paid to shareholders, cash paid
for employee taxes on withholding shares, transactions with noncontrolling
interests, and other financing activities, such as collection of or payments for
deferred consideration in connection with prior year business acquisitions and
divestitures. Generally, the primary drivers of cash flow provided by financing
activities are issuances of debt, changes in net fiduciary liabilities, and
proceeds from issuance of shares.

Share Repurchase Program



We have a share repurchase program authorized by our Board of Directors. The
Repurchase Program was established in April 2012 with $5.0 billion in authorized
repurchases, and was increased by $5.0 billion in authorized repurchases in each
of November 2014, June 2017, and November 2020, and by $7.5 billion in February
2022 for a total of $27.5 billion in repurchase authorizations.

The following table summarizes the Company's Share Repurchase activity (in millions, except per share data):



                                                            Years Ended December 31

At December 31, 2022, the remaining authorized amount for share repurchase under
the Repurchase Program was approximately $6.0 billion. Under the Repurchase
Program, we have repurchased a total of 160.7 million shares for an aggregate
cost of approximately $21.5 billion.

Borrowings

Total debt at December 31, 2022 was $10.8 billion, an increase of $1.4 billion compared to December 31, 2021.

In November 2022, Aon Global Limited's $350 million 4.00% Senior Notes due November 2023 were classified as Short-term debt and current portion of long-term debt in the Consolidated Statement of Financial Position as the date of maturity is in less than one year as of December 31, 2022.


                                       39
--------------------------------------------------------------------------------

In November 2022, Aon Corporation's $500 million 2.20% Senior Notes matured and
were repaid in full. In November 2021, the Company's $500 million 2.20% Senior
Notes due November 2022 were classified as Short-term debt and current portion
of long-term debt in the Consolidated Statements of Financial Position as the
date of maturity is in less than one year as of December 31, 2021.

On September 12, 2022, Aon Corporation, a Delaware corporation, and Aon Global
Holdings plc, a public limited company formed under the laws of England and
Wales, both wholly owned subsidiaries of the Company, co-issued $500 million of
5.00% Senior Notes due September 2032. The Company intends to use the net
proceeds from the offering for general corporate purposes.

On February 28, 2022, Aon Corporation and Aon Global Holdings plc co-issued
$600 million of 2.85% Senior Notes due May 2027 and $900 million of 3.90% Senior
Notes due February 2052. The Company intends to use the net proceeds from the
offering for general corporate purposes.

On December 2, 2021, Aon Corporation and Aon Global Holdings plc co-issued $500
million aggregate principal amount of 2.60% Senior Notes due December 2031. We
intend to use the net proceeds of the offering for general corporate purposes.

million of 2.05% Senior Notes due August 2031 and $600 million of 2.90% Senior
Notes due August 2051. We intend to use the net proceeds from the offering for
general corporate purposes.

On January 13, 2021, Aon Global Limited issued an irrevocable notice of redemption to holders of its 2.80% Senior Notes for the redemption of all $400 million outstanding aggregate principal amount of the notes, which were set to mature in March 2021. The redemption date was on February 16, 2021 and resulted in an insignificant loss due to extinguishment.

Aon Corporation has established a U.S. commercial paper program (the "U.S.
Program") and Aon Global Holdings plc has established a European multi-currency
commercial paper program (the "European Program" and, together with the U.S.
Program, the "Commercial Paper Programs"). Commercial paper may be issued in
aggregate principal amounts of up to $1 billion under the U.S. Program and
€625 million under the European Program, not to exceed the amount of our
committed credit facilities, which was approximately $1.8 billion at
December 31, 2022. The aggregate capacity of the Commercial Paper Program
remains fully backed by our committed credit facilities. Commercial paper
activity during the years ended December 31, 2022 and 2021 is as follows (in
millions):

                                     Years Ended December 31
                                       2022               2021 (2)

Net issuances (repayments)    $         (65)             $    671


(1) The proceeds of the commercial paper issuances were used primarily for
short-term working capital needs.
(2) Proceeds from commercial paper issued by Aon Corporation under the U.S.
Program, where the aggregate principal was raised on July 26, 2021, were used to
pay approximately $400 million of the Termination Fee on July 27, 2021.

Other Liquidity Matters

Distributable Profits



We are required under Irish law to have available "distributable profits" to
make share repurchases or pay dividends to shareholders. Distributable profits
are created through the earnings of the Irish parent company and, among other
methods, through intercompany dividends or a reduction in share capital approved
by the High Court of Ireland. Distributable profits are not linked to a U.S.
GAAP reported amount (e.g. Accumulated deficit). As of December 31, 2022 and
December 31, 2021, we had distributable profits in excess of $29.0 billion and
$32.7 billion, respectively. We believe that we will have sufficient
distributable profits for the foreseeable future.

Credit Facilities



We expect cash generated by operations for 2022 to be sufficient to service our
debt and contractual obligations, finance capital expenditures, and continue to
pay dividends to our shareholders. Although cash from operations is expected to
be sufficient to service these activities, we have the ability to access the
commercial paper markets or borrow under our credit facilities to accommodate
any timing differences in cash flows. Additionally, under current market
conditions, we believe that we could access capital markets to obtain debt
financing for longer-term funding, if needed.

                                       40
--------------------------------------------------------------------------------

As of December 31, 2022, we had two primary committed credit facilities
outstanding: our $1.0 billion multi-currency U.S. credit facility expiring in
September 2026 and our $750 million multi-currency U.S. credit facility expiring
in October 2024. In aggregate, these two facilities provide approximately $1.8
billion in available credit.

Each of these primary committed credit facilities includes customary
representations, warranties, and covenants, including financial covenants that
require us to maintain specified ratios of adjusted consolidated EBITDA to
consolidated interest expense and consolidated debt to consolidated adjusted
EBITDA, tested quarterly. At December 31, 2022, we did not have borrowings under
either facility, and we were in compliance with the financial covenants and all
other covenants contained therein during the rolling year ended December 31,
2022.

Shelf Registration Statement

On May 12, 2020, we filed a shelf registration statement with the SEC,
registering the offer and sale from time to time of an indeterminate amount of,
among other securities, debt securities, preference shares, class A ordinary
shares and convertible securities. Our ability to access the market as a source
of liquidity is dependent on investor demand, market conditions, and other
factors.

Rating Agency Ratings



The major rating agencies' ratings of our debt at February 17, 2023 appear in
the table below.

Letters of Credit and Other Guarantees



We have entered into a number of arrangements whereby our performance on certain
obligations is guaranteed by a third party through the issuance of a LOC. We had
total LOCs outstanding of approximately $74 million at December 31, 2022,
compared to $75 million at December 31, 2021. These LOCs cover the beneficiaries
related to certain of our U.S. and Canadian non-qualified pension plan schemes
and secure deductible retentions for our own workers' compensation program. We
also have obtained LOCs to cover contingent payments for taxes and other
business obligations to third parties, and other guarantees for miscellaneous
purposes at our international subsidiaries.

We have certain contractual contingent guarantees for premium payments owed by
clients to certain insurance companies. The maximum exposure with respect to
such contractual contingent guarantees was approximately $173 million at
December 31, 2022, compared to $153 million at December 31, 2021.

Contractual Obligations

Our contractual obligations and commitments as of December 31, 2022 are comprised of principal payments on debt, interest payments on debt, operating leases, pension and other postretirement benefit plans, and purchase obligations.



Operating leases are primarily comprised of leased office space throughout the
world. As leases expire, we do not anticipate difficulty in negotiating renewals
or finding other satisfactory space if the premise becomes unavailable. In
certain circumstances, we may have unused space and may seek to sublet such
space to third parties, depending upon the demands for office space in the
locations involved. Refer to Note 8 "Lease Commitments" of the Notes to
Consolidated Financial Statements contained in Part II, Item 8 of this report
for further information.

Pension and other postretirement benefit plan obligations include estimates of
our minimum funding requirements pursuant to the ERISA and other regulations, as
well as minimum funding requirements agreed with the trustees of our U.K.
pension plans. Additional amounts may be agreed to with, or required by, the
U.K. pension plan trustees. Nonqualified pension and other postretirement
benefit obligations are based on estimated future benefit payments. We may make
additional discretionary contributions. Refer to Note 11 "Employee Benefits" of
the Notes to Consolidated Financial Statements contained in Part II, Item 8 of
this report for further information.

Purchase obligations are defined as agreements to purchase goods and services
that are enforceable and legally binding on us, and that specifies all
significant terms, including the goods to be purchased or services to be
rendered, the price at which the goods or services are to be rendered, and the
timing of the transactions. Most of our purchase obligations are related to
purchases of information technology services or other service contracts.

                                       41
--------------------------------------------------------------------------------

We had no other cash requirements from known contractual obligations and
commitments that have, or are reasonably likely to have, a current or future
material effect on the Company's financial condition, results of operations, or
liquidity.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES



The Consolidated Financial Statements have been prepared in accordance with
U.S. GAAP. To prepare these financial statements, we make estimates,
assumptions, and judgments that affect what we report as our assets and
liabilities, what we disclose as contingent assets and liabilities at the date
of the Consolidated Financial Statements, and the reported amounts of revenues
and expenses during the periods presented.

In accordance with our policies, we regularly evaluate our estimates,
assumptions, and judgments, including, but not limited to, those concerning
revenue recognition, pensions, goodwill and other intangible assets,
contingencies, share-based payments, and income taxes, and base our estimates,
assumptions, and judgments on our historical experience and on factors we
believe reasonable under the circumstances. The results involve judgments about
the carrying values of assets and liabilities not readily apparent from other
sources. If our assumptions or conditions change, the actual results we report
may differ from these estimates. We believe the following critical accounting
policies affect the more significant estimates, assumptions, and judgments we
use to prepare these Consolidated Financial Statements.

Revenue Recognition



The Company recognizes revenue when control of the promised services is
transferred to the customer in the amount that best reflects the consideration
to which the Company expects to be entitled in exchange for those services. For
arrangements where control is transferred over time, an input or output method
is applied that represents a faithful depiction of the progress towards
completion of the performance obligation. For arrangements that include variable
consideration, the Company assesses whether any amounts should be constrained.
For arrangements that include multiple performance obligations, the Company
allocates consideration based on their relative fair values.

Costs incurred by the Company in obtaining a contract are capitalized and
amortized on a systematic basis that is consistent with the transfer of control
of the services to which the asset relates, considering anticipated renewals
when applicable. Certain contract related costs, including pre-placement
brokerage costs, are capitalized as a cost to fulfill and are amortized on a
systematic basis consistent with the transfer of control of the services to
which the asset relates, which is generally less than one year.

Commercial Risk Solutions includes retail brokerage, specialty solutions, global
risk consulting and captives management, and Affinity programs. Revenue
primarily includes insurance commissions and fees for services rendered. Revenue
is predominantly recognized at a point in time upon the effective date of the
underlying policy (or policies), or for a limited number of arrangements, over
the term of the arrangement using output measures to depict the transfer of
control of the services

                                       44
--------------------------------------------------------------------------------

to customers in an amount that reflects the consideration to which the Company
expects to be entitled in exchange for those services. For arrangements
recognized over time, various output measures, including units delivered and
time elapsed, are utilized to provide a faithful depiction of the progress
towards completion of the performance obligation. Revenue is recorded net of
allowances for estimated policy cancellations, which are determined based on an
evaluation of historical and current cancellation data. Reimbursements received
for out-of-pocket expenses are generally recorded as a component of revenue.
Commissions and fees for brokerage services may be invoiced near the effective
date of the underlying policy or over the term of the arrangement in
installments during the policy period.

Reinsurance Solutions includes treaty reinsurance, facultative reinsurance,
Strategy and Technology Group, and capital markets. Revenue primarily includes
reinsurance commissions and fees for services rendered. Revenue is predominantly
recognized at a point in time upon the effective date of the underlying policy
(or policies), or for a limited number of arrangements, over the term of the
arrangement using output measures to depict the transfer of control of the
services to customers in an amount that reflects the consideration to which the
Company expects to be entitled in exchange for those services. For arrangements
recognized over time, various output measures, including units delivered and
time elapsed, are utilized to provide a faithful depiction of the progress
towards completion of the performance obligation. Commissions and fees for
brokerage services may be invoiced at the inception of the reinsurance period
for certain reinsurance brokerage, or more commonly for treaty reinsurance
arrangements, over the term of the arrangement in installments based on deposit
or minimum premiums.

Health Solutions includes consulting and brokerage, Human Capital, and Consumer
Benefits Solutions. Revenue primarily includes insurance commissions and fees
for services rendered. For brokerage commissions, revenue is predominantly
recognized at the effective date of the underlying policy (or policies), or for
a limited number of arrangements, over the term of the arrangement to depict the
transfer of control of the services to customers in an amount that reflects the
consideration to which the Company expects to be entitled in exchange for those
services using input or output measures, including units delivered or time
elapsed, to provide a faithful depiction of the progress towards completion of
the performance obligation. For Human Capital, revenue is recognized over time
or at a point in time upon completion of the services. For arrangements
recognized over time, revenue is based on a measure of progress that depicts the
transfer of control of the services to the customer utilizing an appropriate
input or output measure to provide a faithful depiction of the progress towards
completion of the performance obligation, including units delivered or time
elapsed. Input and output measures utilized vary based on the arrangement but
typically include reports provided or days elapsed. Revenue from Consumer
Benefits Solutions arrangements are typically recognized upon successful
enrollment of participants. Commissions and fees for brokerage services may be
invoiced at the effective date of the underlying policy or over the term of the
arrangement in installments during the policy period. Payment terms for other
services vary but are typically over the contract term in installments.

Wealth Solutions includes retirement consulting, pension administration and
investments. Revenue recognized for these arrangements is predominantly
recognized over the term of the arrangement using input or output measures to
depict the transfer of control of the services to customers in an amount that
reflects the consideration to which the Company expects to be entitled in
exchange for those services. For consulting arrangements recognized over time,
revenue will be recognized based on a measure of progress that depicts the
transfer of control of the services to the customer, utilizing an appropriate
input or output measure to provide a reasonable assessment of the progress
towards completion of the performance obligation including units delivered or
time elapsed. Fees paid by customers for consulting services are typically
charged on an hourly, project or fixed-fee basis, and revenue for these
arrangements is typically recognized based on time incurred, days elapsed, or
reports delivered. Revenue from time-and-materials or cost-plus arrangements are
recognized as services are performed using input or output measures to provide a
reasonable assessment of the progress towards completion of the performance
obligation including hours worked, and revenue for these arrangements is
typically recognized based on time and materials incurred. Revenue generated
from our delegated investment business is generally earned as an agreed
percentage based on AUM and, to a lesser extent, based on performance fees.
Reimbursements received for out-of-pocket expenses are generally recorded as a
component of revenue. Payment terms vary but are typically over the contract
term in installments.

Pensions

We sponsor defined benefit pension plans throughout the world. Our most significant plans are located in the U.S., the U.K., the Netherlands, and Canada, which are closed to new entrants. We have ceased crediting future benefits relating to salary and services for our U.S., U.K., Netherlands, and Canada plans to the extent statutorily permitted.



The service cost component of net periodic benefit cost is reported in
Compensation and benefits and all other components are reported in Other income
(expense). We used a full-yield curve approach in the estimation of the service
and interest cost components of net periodic pension and postretirement benefit
cost for our major pension and other postretirement benefit plans; this was
obtained by applying the specific spot rates along the yield curve used in the
determination of the benefit obligation to the relevant projected cash flows.

                                       45
--------------------------------------------------------------------------------

Recognition of Gains and Losses and Prior Service



Certain changes in the value of the obligation and in the value of plan assets,
which may occur due to various factors such as changes in the discount rate and
actuarial assumptions, actual demographic experience, and/or plan asset
performance are not immediately recognized in net income. Such changes are
recognized in Other comprehensive income and are amortized into net income as
part of the net periodic benefit cost.

Unrecognized gains and losses that have been deferred in Other comprehensive
income, as previously described, are amortized into expense as a component of
periodic pension expense based on the average life expectancy of the U.S., U.K.,
Netherlands, and Canada plan members. We amortize any prior service expense or
credits that arise as a result of plan changes over a period consistent with the
amortization of gains and losses.

As of December 31, 2022, our pension plans have deferred losses that have not
yet been recognized through income in the Consolidated Financial Statements. We
amortize unrecognized actuarial losses outside of a corridor, which is defined
as 10% of the greater of market-related value of plan assets or PBO. To the
extent not offset by future gains, incremental amortization as calculated above
will continue to affect future pension expense similarly until fully amortized.

The following table discloses our accumulated other comprehensive loss, the number of years over which we are amortizing the loss, and the estimated 2023 amortization of loss by country (in millions, except amortization period):

U.K.                U.S.

Other

Accumulated other comprehensive loss $ 1,761 $ 1,305

    $           437
Amortization period                       7 to 25 years       6 to 23 years       11 to 34 years
Estimated 2023 amortization of loss    $           74      $           34      $            13


The U.S. had no unrecognized prior service cost (credit) at December 31, 2022. The unrecognized prior service cost (credit) at December 31, 2022 was $35 million, and $(6) million for the U.K. and other plans, respectively.



For the U.S. pension plans, we use a market-related valuation of assets approach
to determine the expected return on assets, which is a component of net periodic
benefit cost recognized in the Consolidated Statements of Income. This approach
recognizes 20% of any gains or losses in the current year's value of
market-related assets, with the remaining 80% spread over the next four years.
As this approach recognizes gains or losses over a five-year period, the future
value of assets and therefore, our net periodic benefit cost will be impacted as
previously deferred gains or losses are recorded. As of December 31, 2022, the
market-related value of assets was $1.8 billion. We do not use the
market-related valuation approach to determine the funded status of the U.S.
plans recorded in the Consolidated Statements of Financial Position. Instead, we
record and present the funded status in the Consolidated Statements of Financial
Position based on the fair value of the plan assets. As of December 31, 2022,
the fair value of plan assets was $1.5 billion. Our non-U.S. plans use fair
value to determine expected return on assets.

Rate of Return on Plan Assets and Asset Allocation

The following table summarizes the expected long-term rate of return on plan assets for future pension expense as of December 31, 2022:



                                                              U.K.                U.S.                  Other

                                                      5.34%               6.82%             4.20 - 4.85%


In determining the expected rate of return for the plan assets, we analyze
investment community forecasts and current market conditions to develop expected
returns for each of the asset classes used by the plans. In particular, we
surveyed multiple third-party financial institutions and consultants to obtain
long-term expected returns on each asset class, considered historical
performance data by asset class over long periods, and weighted the expected
returns for each asset class by target asset allocations of the plans.

The U.S. pension plan asset allocation is based on approved allocations following adopted investment guidelines. The investment policy for U.K. and other non-U.S. pension plans is generally determined by the plans' trustees. Because there are several pension plans maintained in the U.K. and other non-U.S. categories, our target allocation presents a range of the target allocation of each plan. Target allocations are subject to change.

Impact of Changing Economic Assumptions

Changes in the discount rate and expected return on assets can have a material impact on pension obligations and pension expense.

Holding all other assumptions constant, the following table reflects what a 25 BPS increase and decrease in our discount rate would have on our PBO at December 31, 2022 (in millions):



                                                                      25 BPS Change in Discount Rate

(1)Increases to the PBO reflect increases to our pension obligations, while decreases in the PBO are recoveries toward fully-funded status. A change in the discount rate has an inverse relationship to the PBO.

pension expense (in millions):

Estimated Future Contributions

We estimate cash contributions of approximately $61 million to our pension plans in 2023 as compared with cash contributions of $59 million in 2022.

Goodwill and Other Intangible Assets

Goodwill represents the excess of purchase price over the fair market value of
the net assets acquired. We classify our intangible assets acquired as either
customer-related and contract-based, technology, tradenames or other
intangibles.

Goodwill is not amortized, but rather tested for impairment at least annually in
the fourth quarter. We test more frequently if there are indicators of
impairment or whenever business circumstances suggest that the carrying value of
goodwill may not be recoverable. These indicators may include a sustained
significant decline in our share price and market capitalization, a significant
decline in our expected future cash flows, or a significant adverse change in
legal factors or in the business climate, among others.

We perform impairment reviews at the reporting unit level. A reporting unit is
an operating segment or one level below an operating segment (referred to as a
"component"). A component of an operating segment is a reporting unit if the
component constitutes a business for which discrete financial information is
available and segment management regularly reviews the operating results of that
component. An operating segment shall be deemed to be a reporting unit if all of
its components are similar, if none of its components are a reporting unit, or
if the segment comprises only a single component. We aggregate components of any
operating segments that have similar economic characteristics into a single
reporting unit.

                                       47
--------------------------------------------------------------------------------

When evaluating these assets for impairment, we may first perform a qualitative
assessment to determine whether it is more likely than not that a reporting unit
is impaired. If we do not perform a qualitative assessment, or if we determine
that it is not more likely than not that the fair value of the reporting unit
exceeds its carrying amount, then the goodwill impairment test becomes a
quantitative analysis. If the fair value of a reporting unit is determined to be
greater than the carrying value of the reporting unit, goodwill is deemed not to
be impaired and no further testing is necessary. If the fair value of a
reporting unit is less than the carrying value, a goodwill impairment loss is
recognized for the amount that the carrying amount of a reporting unit,
including goodwill, exceeds its fair value limited to the total amount of the
goodwill allocated to the reporting unit.

When determining the fair value of our reporting units, we use a DCF model based
on our most current forecasts. We discount the related cash flow forecasts using
the weighted average cost of capital method at the date of evaluation.
Preparation of forecasts and selection of the discount rate for use in the DCF
model involve significant judgments, and changes in these estimates could affect
the estimated fair value of one or more of our reporting units and could result
in a goodwill impairment charge in a future period. We also use market multiples
which are obtained from quoted prices of comparable companies to corroborate our
DCF model results. The combined estimated fair value of our reporting units from
our DCF model often results in a premium over our market capitalization,
commonly referred to as a control premium. We believe the implied control
premium determined by our impairment analysis is reasonable based upon historic
data of premiums paid on actual transactions within our industry.

We review intangible assets that are being amortized for impairment whenever
events or changes in circumstance indicate that an asset group's carrying value
may not be recoverable. If we are required to record impairment charges in the
future, they could materially impact our results of operations.

Contingencies



We define a contingency as an existing condition that involves a degree of
uncertainty as to a possible gain or loss that will ultimately be resolved when
one or more future events occur or fail to occur. Under U.S. GAAP, we are
required to establish reserves for loss contingencies when the loss is probable
and we can reasonably estimate its financial impact. We are required to assess
the likelihood of material adverse judgments or outcomes, as well as potential
ranges or probability of losses. We determine the amount of reserves required,
if any, for contingencies after carefully analyzing each individual item. The
required reserves may change due to new developments in each issue. We do not
recognize gain contingencies until all contingencies are resolved.

Share-Based Payments



Share-based compensation expense is measured based on the grant date fair value
and recognized over the requisite service period for awards that we ultimately
expect to vest. For purposes of measuring share-based compensation expense, we
consider whether an adjustment to the observable market price is necessary to
reflect material nonpublic information that is known to us at the time the award
is granted. No adjustments were necessary for the years ended December 31, 2022,
2021, or 2020. We also estimate forfeitures at the time of grant based on our
actual experience to date and revise our estimates, if necessary, in subsequent
periods if actual forfeitures differ from those estimates.

Restricted Share Units



RSUs are service-based awards for which we recognize the associated compensation
cost on a straight-line basis over the requisite service period. We estimate the
fair value of the awards based on the market price of the underlying share on
the date of grant, reduced by the present value of estimated dividends foregone
during the vesting period where applicable.

Performance Share Awards



PSAs are performance-based awards for which vesting is dependent on the
achievement of certain objectives. Such objectives may be made on a personal,
group or company level. We estimate the fair value of the awards based on the
market price of the underlying share on the date of grant, reduced by the
present value of estimated dividends foregone during the vesting period.

Compensation expense is recognized over the performance period. The number of
shares issued on the vesting date will vary depending on the actual performance
objectives achieved, which are based on a fixed number of potential outcomes. We
make assessments of future performance using subjective estimates, such as
long-term plans. As a result, changes in the underlying assumptions could have a
material impact on the compensation expense recognized.

The largest plan is the LPP, which has a three-year performance period. As the
percent of expected performance increases or decreases, the potential change in
expense can go from 0% to 200% of the targeted total expense. The 2020 to 2022
performance period ended on December 31, 2022, the 2019 to 2021 performance
period ended on December 31, 2021, and the 2018 to 2020 performance period ended
on December 31, 2020. The LPP currently has two open performance periods: 2021
to

                                       48
--------------------------------------------------------------------------------

2023 and 2022 to 2024. A 10% upward adjustment in our estimated performance
achievement percentage for both open performance periods would have increased
our 2022 expense by approximately $2.6 million, while a 10% downward adjustment
would have decreased our expense by approximately $7.7 million.

Income Taxes

We earn income in numerous countries and this income is subject to the laws of taxing jurisdictions within those countries.



The carrying values of deferred income tax assets and liabilities reflect the
application of our income tax accounting policies and are based on management's
assumptions and estimates about future operating results and levels of taxable
income, and judgments regarding the interpretation of the provisions of current
accounting principles.

Deferred tax assets are reduced by valuation allowances if, based on the
consideration of all available evidence, it is more likely than not that some
portion of the deferred tax asset will not be realized. Considerations with
respect to the realizability of deferred tax assets include the period of
expiration of the deferred tax asset, historical earnings and projected future
taxable income by jurisdiction as well as tax liabilities for the tax
jurisdiction to which the tax asset relates. Significant management judgment is
required in determining the assumptions and estimates related to the amount and
timing of future taxable income. Valuation allowances are evaluated periodically
and will be subject to change in each future reporting period as a result of
changes in various factors.

We assess carryforwards and tax credits for realization as a reduction of future taxable income by using a "more likely than not" determination.



We base the carrying values of liabilities and assets for income taxes currently
payable and receivable on management's interpretation of applicable tax laws and
incorporate management's assumptions and judgments about using tax planning
strategies in various taxing jurisdictions. Using different estimates,
assumptions, and judgments in accounting for income taxes, especially those that
deploy tax planning strategies, may result in materially different carrying
values of income tax assets and liabilities and changes in our results of
operations.

NEW ACCOUNTING PRONOUNCEMENTS



Note 2 "Summary of Significant Accounting Principles and Practices" of the Notes
