general economic conditions in different countries in which Aon does business

that could affect the return on invested assets; changes in the funding status
of Aon's various defined benefit pension plans and the impact of any increased
pension funding resulting from those changes; rating agency actions that could
affect Aon's ability to borrow funds; fluctuations in exchange and interest
rates that could influence revenue and expense; the impact of class actions
and individual lawsuits including client class actions, securities class
actions, derivative actions and ERISA class actions; the impact of any
investigations brought by regulatory authorities in the U.S., U.K. and other
countries; the cost of resolution of other contingent liabilities and loss
contingencies, including potential liabilities arising from error and
omissions claims against Aon; the failure to retain and attract qualified
personnel; the impact of, and potential challenges in complying with,

in the future, to clients; the possibility that the expected efficiencies and
cost savings from the merger with Hewitt Associates Inc. ("Hewitt") will not
be realized, or will not be realized within the expected time period; the risk
that the Aon and Hewitt businesses will not be integrated successfully; Aon's
ability to implement restructuring initiatives and other initiatives intended
to yield cost savings, and the ability to achieve those cost savings; the
potential of a system or network disruption resulting in operational
interruption or improper disclosure of personal data; any inquiries relating
