The estimated net actuarial loss and prior service cost for defined benefit pension plans that will be amortized from accumulated other comprehensive income (loss) into net periodic benefit cost during the 2011 fiscal year is $3.3 million and $0.2 million, respectively.

During the first nine months of 2011 and 2010, the Company contributed $5.7 million and $3.9 million, respectively, to defined benefit pension plans. The Company expects to contribute an additional $1.3 million, for total contributions of $7.0 million in 2011. The Company contributed a total of $4.1 million in 2010. The assumptions used in the valuation of the Company's pension plans and in the target investment allocation have remained the same as those disclosed in the Company's 2010 Annual Report on Form 10-K filed on March 2, 2011.
