Income Taxes:

Income taxes were accrued at an estimated effective tax rate of 33% and 34% in the first nine months of 2012 and 2011, respectively. The effective tax rate differs from that computed at the federal statutory rate of 35% principally because of the effect of foreign and state income taxes, tax credits, deductions for domestic production activities and discrete tax items.
