The matters which affect the comparability of the quarterly results include the following:

• Seasonality: The Company’s revenues and operating income reflect the industry’s seasonality and as a result are lower in the first quarter and higher in the third quarter.

• Investment income and losses: The Company’s net income reflects gains and losses related to the Company’s investments held in non-qualified retirement plans and are subject to market conditions.

• Year Ended December 31, 2011 results:

• Termination benefits: The Company’s operating results include employee termination benefits for the first, second, third and fourth quarters totaling $0.1 million, $0.3 million, $0.4 million and $3.6 million, respectively.

• Land held for Sale: During the first quarter, the Company recorded a $1.8 million loss on assets held for sale resulting from the reduction of the carrying amount of a parcel of land held for sale to its estimated fair value.

• Income taxes: The Company's first quarter 2011 income taxes reflect a $1.4 million adjustment that reduced the current federal taxes payable. Income taxes for the third quarter of 2011 were impacted by the identification of $1.7 million of additional federal tax benefits, $0.4 million of foreign tax credits for open tax years and an adjustment of $1.9 million for unrecognized tax positions.

• Year Ended December 31, 2010 results:

• Termination benefits: The Company’s operating results include employee termination benefits for the first, second, third and fourth quarters totaling $0.4 million, $(0.1) million, $0.3 million and $1.2 million, respectively.

• Income taxes: The Company’s third quarter 2010 income taxes reflect a $3.3 million adjustment to the Company’s deferred tax assets and the identification of $1.6 million of additional federal income tax benefits, partially offset by an increase of $1.6 million related to the identification of unrecognized tax positions.
