Year Ended December 31, 2011 Compared with Year Ended December 31, 2010
Premium income for group life and accidental death and dismemberment increased in 2011 compared to 2010 due primarily to higher
group life sales, partially offset by lower premium persistency in the large case group life products. Case persistency in 2011 was slightly
higher than 2010. Net investment income was higher in 2011 compared to 2010 due primarily to an increase in the level of assets
supporting this line of business, partially offset by a decline in the level of prepayment income on mortgage-backed securities.
The 2011 benefit ratio was consistent with the benet ratio of 2010. Commissions and the deferral of acquisition costs were higher in
2011 compared to 2010 due primarily to a higher level of group life sales. The amortization of acquisition costs in 2011 was slightly lower
than in 2010, due primarily to volatility in the level of amortization associated with internal replacement transactions. The other expense
ratio in 2011 was consistent with 2010 as we continue our efforts to manage our expense levels relative to premium levels through
operating effectiveness and expense management.
