Use of Non-GAAP Financial Measures

A non-GAAP financial measure is a numerical measure of performance, financial position, or
cash flows that includes adjustments from a comparable financial measure presented in
accordance with U.S. GAAP.  

The company uses a number of non-GAAP financial measures that management believes
are useful to investors because they illustrate the performance of the company’s normal,
ongoing operations which is important in understanding and evaluating the company’s
financial condition and results of operations.  While such measures are also consistent with
measures utilized by investors to evaluate performance, they are not a substitute for U.S.
GAAP financial measures.  Therefore, in the back of the handouts, the company has
provided reconciliations of the non-GAAP financial measures to the most directly
comparable U.S. GAAP financial measure.  The company adjusts U.S. GAAP financial
measures for items not directly related to ongoing operations.  However, it is possible that
these adjusting items have occurred in the past and could recur in the future.  Management
also uses non-GAAP financial measures for goal setting, to determine employee and senior
management awards and compensation, and to evaluate performance on a basis
comparable to that used by investors and securities analysts.  

The company also uses a variety of other measures not considered to be non-GAAP
financial measures.  These are operational measures and do not have U.S. GAAP
counterparts.  Assets under management is an example of an operational measure.

Forward Looking Statements

Certain statements made by the company which are not historical facts may be considered
forward-looking statements, including, without limitation, statements as to sales targets, sales
and earnings trends, and management’s beliefs, expectations, goals and opinions.  The
company does not undertake to update these statements, which are based on a number of
assumptions concerning future conditions that may ultimately prove to be inaccurate.  Future
events and their effects on the company may not be those anticipated, and actual results may
differ materially from the results anticipated in these forward-looking statements.

The risks, uncertainties and factors that could cause or contribute to such material differences
are discussed in the company’s Annual Report on Form 10-K for the year ended December
31, 2006 and in the company’s quarterly report on Form 10-Q for the quarter ended
September 30, 2007, filed by the company with the Securities and Exchange Commission.
These risks and uncertainties include, without limitation: competitive factors; volatility of
financial markets; decrease in ratings; interest rate changes; inability to attract and retain
sales representatives; international business risks; foreign currency exchange rate
fluctuations; a pandemic, terrorist attack or other catastrophic event; default of the company's
re-insurers; and investment portfolio risks.
