Provide journal entries to record the income tax expense for 2013 through 2015. You may indicate the sum of the changes in the various Page deferred tax assets/liabilities by a single debit or credit to the Net deferred tax asset/liability account. 2. Refer to the deferred tax asset and liability items reported by Pepsico at December 31, 2015 and 2014. For each item (except Other), determine whether the balance changed because of a net originating or net reversing temporary difference. Provide a likely explanation for each of the temporary differences and clearly discuss whether it indicates a higher or lower financial reporting revenue or expense relative to the amount reported in the 2015 tax return. 3. Pepsico's reported deferred tax expense in 2015 (minus $40 million) does not equal the reported decrease in net deferred tax liability ($4,429 - $4,268 = $161 million) over the course of 2015. What is the likely source of this discrepancy
