[1] The income tax expense attributable to WhiteWave during the nine months ended September 30, 2013 includes approximately $31.1 million related to certain deferred intercompany transactions which were recognized upon the completion of the WhiteWave spin-off. Because these liabilities arose as a direct result of the spin-off of WhiteWave, we have reflected the income statement impact of such liabilities as a component of discontinued operations.
