[1] (C)In the fourth quarter of 2012, we determined that an additional valuation allowance on our U.S. deferred tax assets was required, due in part to our current domestic performance, which include continued fourth quarter deterioration and cumulative losses as of October 31, 2012 which included fourth quarter warranty charges. As a result we recognized income tax expense of $2 billion for the increase in the valuation allowance. In the fourth quarter of 2012, we also recognized $233 million of income tax expense related to the reversal of income tax benefits recognized in the first, second, and third quarters of 2012. In the fourth quarter of 2013, our North America Truck segment recorded a non-cash charge of $77 million to reflect impairment of goodwill as a result of changes in our organizational and reporting structures, which resulted in a change in certain of our reporting units. The impairment charges were included in Asset impairment charges.Also in the fourth quarter of 2013, the Company met the criteria necessary to apply the exception within the intraperiod tax allocation rules. As a result, the Company recorded an income tax benefit of $220 million, which was recorded in Income tax benefit (expense) related to continuing operations.
