19 Important disclosures regarding forward-looking statements This presentation contains certain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, and Section 21E of the Securities Exchange Act of 1934, which are intended to be covered by the safe harbors created by those laws. These forward-looking statements include information about possible or assumed future results of our operations. All statements, other than statements of historical facts, included in this document that address activities, events or developments that we expect or anticipate may occur in the future, including such things as our outlook, potential cost savings and accelerated adjusted operating margin and adjusted earnings per share growth, future capital expenditures, growth in commissions and fees, business strategies, competitive strengths, goals, the benefits of new initiatives, growth of our business and operations, plans, and references to future successes are forward-looking statements. Also, when we use the words such as ‘anticipate’, ‘believe’, ‘estimate’, ‘expect’, ‘intend’, ‘plan’, ‘probably’, or similar expressions, we are making forward-looking statements. There are important uncertainties, events and factors that could cause our actual results or performance to differ materially from those in the forward-looking statements contained in this document, including the following: the following: the impact of any regional, national or global political, economic, business, competitive, market, environmental or regulatory conditions on our global business operations; the impact of current financial market conditions on our results of operations and financial condition, including as a result of those associated with the current Eurozone sovereign debt crisis any insolvencies of or other difficulties experienced by our clients, insurance companies or financial institutions; our ability to implement and realize anticipated benefits of the 2011 Operational Review or any revenue generating initiatives; the volatility or declines in insurance markets and premiums on which our commissions are based, but which we do not control; our ability to continue to manage our significant indebtedness; our ability to compete effectively in our industry, including the impact of our refusal to accept contingent commissions from carriers in the non-Employee Benefit areas of our retail brokerage business; material changes in commercial property and casualty markets generally or the availability of insurance products or changes in premiums resulting from a catastrophic event, such as a hurricane, or otherwise; our ability to retain key employees and clients and attract new business; the timing and ability to carry out share repurchases and redemptions; the timing or ability to carry out refinancing or take other steps to manage our capital and the limitations in our long-term debt agreements that may restrict our ability to take these actions; any fluctuations in exchange and interest rates that could affect expenses and revenue; the potential costs and difficulties in complying with a wide variety of foreign laws and regulations and any related changes, given the global scope of our operations; rating agency actions that could inhibit our ability to borrow funds or the pricing thereof; a significant decline in the value of investments that fund our pension plans or changes in our pension plan liabilities or funding obligations; our ability to achieve the expected strategic benefits of transactions; the impairment of the goodwill of one of our reporting units, in which case we may be required to record significant charges to earnings; our ability to receive dividends or other distributions in needed amounts from our subsidiaries; changes in the tax or accounting treatment of our operations; any potential impact from the US healthcare reform legislation; our involvements in and the results of any regulatory investigations, legal proceedings and other contingencies; underwriting, advisory or reputational risks associated with non-core operations as well as the potential significant impact our non-core operations (including our Loan Protector operations) can have on our financial results; our exposure to potential liabilities arising from errors and omissions and other potential claims against us; and the interruption or loss of our information processing systems or failure to maintain secure information systems. The foregoing list of factors is not exhaustive and new factors may emerge from time to time that could also affect actual performance and results.

Although we believe that the assumptions underlying our forward-looking statements are reasonable, any of these assumptions, and therefore also the forward- looking statements based on these assumptions, could themselves prove to be inaccurate. In light of the significant uncertainties inherent in the forward-looking statements included in this presentation, our inclusion of this information is not a representation or guarantee by us that our objectives and plans will be achieved. Our forward-looking statements speak only as of the date made and we will not update these forward-looking statements unless the securities laws require us to do so. In light of these risks, uncertainties and assumptions, the forward-looking events discussed in this presentation may not occur, and we caution you against unduly relying on these forward-looking statements. |
