[1] The amount of interest paid, net of amount capitalized and cash paid for income taxes paid, net of refunds, for the periods prior to the Separation was not distinguishable for the Company. These amounts were combined with the Former Parent. Due to the legal organizational structure, capital structure, as well as income tax compliance requirements, the amounts for the Company are indivisible from those that were included with the Former Parent. The amounts disclosed for income taxes paid, net of refunds represent all distinguishable amounts, which includes domestic taxes paid after the Separation and foreign taxes paid for the entire fiscal year.
