(1) Performance share awards are included in diluted weighted average number of shares outstanding based upon what would be issued if the end of the most recent reporting period was the end of the term of the award. The dilutive share calculation for 2010 excludes 107,516 shares under outstanding performance share awards because the inclusion of these awards would have been antidilutive under the treasury stock method.
