INCOME TAXES

NOTE 12 — INCOME TAXES

The effective tax rate was 37.3% and 20.4% for the three months ended July 31, 2012 and 2011, respectively; and 32.6% and 22.3% for the nine months ended July 31, 2012 and 2011, respectively. The change in the effective tax rate was primarily attributable to a shift in global earnings mix to tax jurisdictions with higher tax rates and other discrete items recognized during the period.

The Company has estimated the reasonably possible expected net change in unrecognized tax benefits through July 31, 2012 based on expected settlements or payments of uncertain tax positions, and lapses of the applicable statutes of limitations of unrecognized tax benefits under ASC 740, “Income Taxes.” The estimated net decrease in unrecognized tax benefits for the next 12 months ranges from $0 to $48.5 million. Actual results may differ materially from this estimate.
