Third quarter 2010 operating profit increased by 26.9 percent to $274 million, or 8.5 percent of sales, compared to $216 million, or 7.4 percent of sales, in the 2009 third quarter.
Interest expense decreased significantly to $67 million in the 2010 third quarter from $88 million in the 2009 third quarter due to lower average outstanding borrowings resulting from the Company's repurchases of long-term obligations. During the 2010 third quarter, the Company repurchased an additional $65 million of its long-term obligations, resulting in a charge, which is included in Other (income) expense of $8 million ($5 million, net of income taxes).
The effective income tax rate for the 2010 quarter was 35.6 percent compared to a rate of 41.0 percent for the 2009 quarter. The decrease in the income tax rate was primarily associated with income tax examination related activity. In the 2009 period, income tax expense was increased due to unfavorable income tax examination results while the 2010 period reflected decreases due to the elimination of selected income tax reserves upon the effective resolution of the respective uncertain tax positions.
