Such statements are based upon the current beliefs and expectations of Willis Towers Watson’s management and are subject to significant risks and uncertainties. Actual results may differ from those set forth in the forward - looking statements. All forward - looking disclosure is speculative by its nature. There are important risks, uncertainties, events and factors that could cause our actual results or performance to differ materially from those in the forward - looking statements contained herein, including the following: the ability of the company to successfully establish, execute and achieve its global business strategy as it evolves; changes in demand for our services, including any decline in defined benefit pension plans or the purchasing of insurance; changes in general economic, business and political conditions, including changes in the financial markets; significant competition that the company faces and the potential for loss of market share and/or profitability; the impact of seasonality and differences in timing of renewals; the risk of increased liability or new legal claims arising from our new and existing products and services, and expectations, intentions and outcomes relating to outstanding litigation; the risk the Stanford litigation settlement approval will be overturned on appeal, the risk that the Stanford bar order may be challenged in other jurisdictions, and the risk that the charge related to the Stanford settlement may not be deductible; the risk of material adverse outcomes on existing litigation or investigation matters; changes in the regulatory environment in which the company operates, including, among other risks, the impact of pending competition law and regulatory investigations; various claims, government inquiries or investigations or the potential for regulatory action; the company’s ability to make divestitures or acquisitions and its ability to integrate or manage such acquired businesses (including the recently completed acquisition of TRANZACT); failure to protect client data or breaches of information systems; the ability to comply with complex and evolving regulations related to data privacy and cyber security; the potential impact of Brexit; our ability to successfully enhance our billing, collection and other working capital efforts, and thereby increase our free cash flow; the potential impact of the change in the method for determining LIBOR; the ability of the company to properly identify and manage conflicts of interest; reputational damage; reliance on third - party services; the loss of key employees; the ability to successfully manage ongoing organizational changes; disasters or business continuity problems; doing business internationally, including the impact of exchange rates; compliance with extensive government regulation; the risk of sanctions imposed by governments, or changes to associated sanction regulations; technological change; changes and developments in the insurance industry or the United States healthcare system; the risk that the company may not be able to repurchase the intended number of outstanding shares due to M&A activity or investment opportunities, market or business conditions, or other factors; the inability to protect the company’s intellectual property rights, or the potential infringement upon the intellectual property rights of others; fluctuations in the company’s pension liabilities; the ability of the company to meet its financial guidance, the company’s capital structure, including indebtedness amounts, the limitations imposed by the covenants in the documents governing such indebtedness and the maintenance of the financial and disclosure controls and procedures of each; the ability of the company to obtain financing on favorable terms or at all; adverse changes in the credit ratings of the company; the impact of recent changes to U.S. tax laws, including on our effective tax rate, and the enactment of additional, or the revision of existing, state, federal, and/or foreign regulatory and tax laws and regulations; U.S. federal income tax consequences to U.S. persons owning at least 10% of the company’s shares; changes in accounting principles, estimates or assumptions; fluctuation in revenue against the company’s relatively fixed expenses; the laws of Ireland being different from the laws of the United States and potentially affording less protections to the holders of our securities; and the company's holding company structure potentially preventing it from being able to receive dividends or other distributions in needed amounts from our subsidiaries. These factors also include those described under “Risk Factors” in the company’s most recent 10 - K filing and subsequent filings filed with the SEC.

Willis Towers Watson Non - GAAP Measures willistowerswatson.com © 2019 Willis Towers Watson. All rights reserved. 2 In order to assist readers of our consolidated financial statements in understanding the core operating results that Willis Towers Watson’s management uses to evaluate the business and for financial planning, we present the following non - GAAP measures: (1) Constant Currency Change, (2) Organic Change, (3) Adjusted Operating Income, (4) Adjusted EBITDA, (5) Adjusted Net Income, (6) Adjusted Diluted Earnings Per Share, (7) Adjusted Income Before Taxes, (8) Adjusted Income Taxes/Tax Rate and (9) Free Cash Flow. The Company believes that these measures are relevant and provide useful information widely used by analysts, investors and other interested parties in our industry to provide a baseline for evaluating and comparing our operating performance, and in the case of free cash flow, our liquidity results. Reconciliations of these measures are included in the accompanying appendix of these earning release supplemental materials. The Company does not reconcile its forward looking non - GAAP financial measures to the corresponding U.S. GAAP measures, due to variability and difficulty in making accurate forecasts and projections and/or certain information not being ascertainable or accessible; and because not all of the information, such as foreign currency impacts necessary for a quantitative reconciliation of these forward - looking non - GAAP financial measures to the most directly comparable U.S. GAAP financial measure, is available to the Company without unreasonable efforts. For the same reasons, the Company is unable to address the probable significance of the unavailable information. The Company provides non - GAAP financial measures that it believes will be achieved, however it cannot accurately predict all of the components of the adjusted calculations and the U.S. GAAP measures may be materially different than the non - GAAP measures.
