Forward-looking statements are subject to inherent risks and uncertainties that could cause actual results to differ materially from those expressed or implied in our forward-looking statements. Factors that could materially affect our future results include, among other things:

• our ability to compete effectively and adapt to changes in the competitive environment, including to respond to technological change, disintermediation, digital disruption and other types of innovation;
• the impact from lawsuits, other contingent liabilities and loss contingencies arising from errors and omissions, breach of fiduciary duty or other claims against us;
• our ability to attract and retain industry leading talent;
• our organization's ability to maintain adequate safeguards to protect the security of our information systems and confidential, personal or proprietary information, particularly given the large volume of our vendor network and the need to identify and patch software vulnerabilities, including those in the existing JLT information systems;
• our ability to successfully integrate or achieve the intended benefits of our acquisitions, including JLT;
• the impact of investigations, reviews, or other activity by regulatory or law enforcement authorities, including the ongoing investigation by the European Commission competition authority;
• our ability to maintain our credit ratings and repay our outstanding long-term debt in a timely manner and on favorable terms, including approximately $6.8 billion issued in connection with the acquisition of JLT;
• the regulatory, contractual and reputational risks that arise based on insurance placement activities and various insurer revenue streams;
• the financial and operational impact of complying with laws and regulations where we operate and the risks of noncompliance with such laws, including cybersecurity and data privacy regulations such as the E.U.'s General Data Protection Regulation, anti-corruption laws such as the U.S. Foreign Corrupt Practices Act, U.K. Anti-Bribery Act and trade sanctions regimes;
• our ability to manage risks associated with our investment management and related services business, including potential conflicts of interest between investment consulting and fiduciary management services;
• the impact of macroeconomic, political, regulatory or market conditions on us, our clients and the industries in which we operate, including the impact of Brexit or the inability to collect on our receivables;
• our ability to successfully recover if we experience a business continuity problem due to cyberattack, natural disaster, pandemic or otherwise; and
• the impact of changes in tax laws, guidance and interpretations, including certain provisions of the U.S. Tax Cuts and Jobs Act, or disagreements with tax authorities.

Supplemental Information - Revenue Analysis

Three Months Ended December 31

(Millions) (Unaudited)

The Company conducts business in more than 130 countries. As a result, foreign exchange rate movements may impact period-to-period comparisons of revenue. Similarly, certain other items such as the revenue impact of acquisitions and dispositions, including transfers among businesses, may impact period-to-period comparisons of revenue. Underlying revenue measures the change in revenue from one period to the next by isolating these impacts.

The calculation of underlying revenue growth for the three months ended December 31, 2019 includes the results of JLT. The column "2018 Including JLT" includes JLT's prior year fourth quarter revenue (See reconciliation of non-GAAP measures on page 14). All other acquisitions/dispositions activity is included in the acquisitions/dispositions column.

Reconciliation of Non-GAAP Measures - Actual as Reported

Three Months Ended December 31

(Millions) (Unaudited)

Overview

The Company reports its financial results in accordance with accounting principles generally accepted in the United States (referred to in this release as "GAAP" or "reported" results). The Company also refers to and presents below certain additional non-GAAP financial measures, within the meaning of Regulation G under the Securities Exchange Act of 1934. These measures are: adjusted operating income (loss), adjusted operating margin, adjusted income, net of tax and adjusted earnings per share (EPS). The Company has included reconciliations of these non-GAAP financial measures to the most directly comparable financial measure calculated in accordance with GAAP in the following tables.

The Company believes these non-GAAP financial measures provide useful supplemental information that enables investors to better compare the Company's performance across periods. Management also uses these measures internally to assess the operating performance of its businesses, to assess performance for employee compensation purposes and to decide how to allocate resources. However, investors should not consider these non-GAAP measures in isolation from, or as a substitute for, the financial information that the Company reports in accordance with GAAP. The Company's non-GAAP measures include adjustments that reflect how management views our businesses, and may differ from similarly titled non-GAAP measures presented by other companies.

Adjusted Operating Income (Loss) and Adjusted Operating Margin

Adjusted operating income (loss) is calculated by excluding the impact of certain noteworthy items from the Company's GAAP operating income or (loss). The following tables identify these noteworthy items and reconcile adjusted operating income (loss) to GAAP operating income or loss, on a consolidated and segment basis, for the three and twelve months ended December 31, 2019 and 2018. The following tables also present adjusted operating margin. In 2019, the Company changed its methodology for calculating adjusted operating margin due to the significant amount of identified intangible asset amortization related to the JLT Transaction on April 1, 2019. For the three and twelve months ended December 31, 2019 and 2018, adjusted operating margin is calculated by dividing the sum of adjusted operating income plus identified intangible asset amortization by consolidated or segment adjusted revenue.

The information presented below represents the actual as reported results for the three months ended December 31, 2019 and 2018. Results for the three months ended December 31, 2018 are for MMC only, as previously reported, and do not include JLT results.

Adjusted income, net of tax is calculated as the Company's GAAP income from continuing operations, adjusted to reflect the after tax impact of the operating income adjustments set forth in the preceding tables and investments gains or losses related to the impact of mark-to-market adjustments on certain equity securities and adjustments to provisional 2017 tax estimates. Adjustments also include JLT acquisition related items, including change in fair value of derivative contracts, financing costs and interest income on funds held in escrow. Adjusted EPS is calculated by dividing the Company's adjusted income, net of tax, by MMC's average number of shares outstanding-diluted for the relevant period. The following tables reconcile adjusted income, net of tax to GAAP income from continuing operations and adjusted EPS to GAAP EPS for the three and twelve months ended December 31, 2019 and 2018.

Reconciliation of Non-GAAP Measures - 2018 Revenue Including JLT

Three and Twelve Months Ended December 31, 2018

(Millions) (Unaudited)

On April 1, 2019, the Company completed its previously announced acquisition of Jardine Lloyd Thompson Group, plc. JLT results of operations for the three months ended December 31, 2019 are included in the Company's results of operations for the fourth quarter of 2019. Prior periods in 2018 do not include JLT's results. Prior to being acquired by the Company, JLT operated in three segments, Specialty, Reinsurance and Employee Benefits. As of April 1, 2019, the historical JLT businesses were combined into MMC operations as follows: JLT Specialty was included by geography within Marsh, JLT Reinsurance was included within Guy Carpenter and the majority of the JLT Employee Benefits business was included in Mercer Health and Wealth.

The JLT Transaction had a significant impact on the Company's results of operations in 2019. The Company believes that in addition to the change in reported GAAP revenue, a comparison of 2019 revenue to the combined 2018 revenue of MMC and JLT would provide investors useful information about the year-over-year results.

The table below sets forth revenue information as if the companies were combined on April 1, 2018. Consistent with consolidated revenue in 2019, the twelve months ended December 31, 2018 does not include JLT revenue for the period from January 1 to March 31, 2018. JLT 2018 revenue information is derived from the "JLT Supplemental Information - Revenue Analysis" furnished to the SEC on June 6, 2019 on Form 8-K and includes the revenue from JLT's aerospace business. Please see the notes to the supplemental information on that Form 8-K for additional information.
