Comprehensive Income

The difference between comprehensive income and net income was due to foreign currency translation adjustments and pension and other post-retirement benefit adjustments, as summarized below. The decrease in other comprehensive income for the three and six months ended June 30, 2013 as compared to 2012 is attributed to fluctuations in the Australian and Canadian exchange rates in 2013.
