| [1]Operating earnings and net earnings from continuing operations in 2012 were impacted by charges totaling $8,834 ($5,917 net of tax), comprising merger and transaction costs of $6,901 ($4,486 net of tax), restructuring and exit costs of $2,521 ($1,866 net of tax), and foreign currency gains of $588 ($435 net of tax). Fourth quarter 2012 operating earnings and net earnings include foreign currency gains which pertain to prior annual periods of $1,465 ($1,026 net of tax). Prior annual periods were not corrected as such amounts were immaterial and thus recorded in the fourth quarter of 2012.[2]Operating earnings and net earnings from continuing operations in the fourth quarter of 2011 were impacted by charges totaling $41,067 ($28,813 net of tax), comprising goodwill impairments of $40,455 ($28,435 net of tax), restructuring and exit costs of $634 ($393 net of tax), and foreign currency gains of $22 ($15 net of tax). |

| - Definition
This element represents the weighted average total number of shares issued throughout the period including the first (beginning balance outstanding) and last (ending balance outstanding) day of the period before considering any reductions (for instance, shares held in treasury) to arrive at the weighted average number of shares outstanding. Weighted average relates to the portion of time within a reporting period that common shares have been issued and outstanding to the total time in that period. Such concept is used in determining the weighted average number of shares outstanding for purposes of calculating earnings per share (basic).
