[1] Results for the fourth quarter of 2012 were unfavorably impacted by the Company's decision to withdraw from the Graphic Communications Conference International Brotherhood of Teamsters National Pension Fund. An estimated withdrawal liability of $31,683 was recorded in the fourth quarter of 2012.

[2] Results for the fourth quarter of 2011 were favorably impacted by a decrease in the effective tax rate for the quarter. The decrease in the effective tax rate was principally due to discrete period tax benefits related to the release of certain valuation allowances in the amount of $2,124, primarily for the Company's Australian subsidiary. In addition, the fourth quarter of 2011 operating results were favorably impacted by the reduction of an estimated contingent consideration liability in the amount of $3,320, related to a 2010 acquisition, and $825 related to the reduction of an employment tax reserve for a 2008 acquisition.

[3] Results for the third quarter of 2011 were favorably impacted by a decrease in the effective tax rate for the quarter. The decrease in the effective tax rate was principally due to discrete period tax benefits related to the release of certain valuation allowances in the amount of $4,008, primarily for the Company's United Kingdom subsidiary.
