those contemplated by the forward-looking statements: (1) sustained

liabilities and claim payments due to changes in claim incidence,
recovery rates, mortality and morbidity rates, and policy benefit
offsets due to, among other factors, the rate of unemployment and
consumer confidence, the emergence of new diseases, epidemics, or
pandemics, new trends and developments in medical treatments, the
effectiveness of our claims operational processes, and changes in
governmental programs; (3) unfavorable economic or business conditions,

limited to, changes in interest rates, defaults, changes in credit
spreads, impairments, and the lack of appropriate investments in the
market which can be acquired to match our liabilities; (8) increased

industry consolidation, new entrants to our markets, or other factors;
(9) changes in our financial strength and credit ratings; (10) our
ability to execute on our technology system upgrades or replacements;
(11) damage to our reputation due to, among other factors, regulatory

litigation; (16) availability of reinsurance in the market and the
