The increase in the effective tax rate for Duke Energy for the three months ended September 30, 2014 is primarily due to a favorable deferred state tax adjustment in the third quarter of 2013. The decrease in the effective tax rate for Duke Energy Carolinas for the three months ended September 30, 2014 is primarily due to an increase in the tax benefit related to the manufacturing deduction in 2014 as the prior year deduction was limited by taxable income. The decrease in the effective tax rate for Duke Energy Carolinas for the nine months ended September 30, 2014 is primarily due to favorable audit settlements, changes in apportionment related to state income tax, and the tax benefit related to the manufacturing deduction in 2014 as the prior year deduction was limited by taxable income. The decrease in the effective tax rate for Progress Energy for the three months ended September 30, 2014 is primarily due to certain nondeductible book depreciation.
