[1] In 2012 for pension benefits, the weighted average discount rate used to compute the expense for the period of November 1, 2011 through July 31, 2012 was 4.2%. Due to plan remeasurements at July 31, 2012 at a rate of 3.3%, the weighted average discount rate for the full fiscal year 2012 was 4.1%. In 2010 for health and life insurance benefits, the weighted average discount rate used to compute the expense for the period of November 1, 2009 through March 31, 2010 was 5.5%. Due to a plan remeasurement at March 31, 2010 at a rate of 5.6%, the weighted average discount rate for the full fiscal year 2010 was 5.6%.
[2] For both October 31, 2012 and 2011, the totals exclude $8 million of receivables, which are included in the change in plan assets table. In addition, the table above includes the fair value of Canadian pension assets translated at the exchange rates as of October 31, 2012 and 2011, respectively, while the change in plan asset table includes the fair value of Canadian pension assets translated at historical foreign currency rates.
