| [1]Manufacturing gross margin is calculated by subtracting Costs of products sold from Sales of manufactured products, net.[2]We record adjustments to our product warranty accrual to reflect changes in our estimate of warranty costs for products sold in prior periods. Such adjustments typically occur when claims experience deviates from historic and expected trends. In the third quarter of 2014, we recognized a benefit for adjustments to pre-existing warranties of $(29) million. The benefit is comprised of a benefit for changes in estimates of $(59) million, partially offset by a $30 million correction of prior-period errors, primarily related to pre-existing warranties. In the fourth quarter of 2014, we recognized a benefit for adjustments to pre-existing warranties of $(10) million compared to a charge for adjustments to pre-existing warranties of $152 million in the fourth quarter of 2013. The $(10) million benefit recorded in the fourth quarter of 2014 is comprised of a benefit for changes in estimates of $(35) million, partially offset by the fourth quarter impact of $25 million relating to the correction of prior-period errors as discussed in Note 1, 2014 Out-Of-Period Adjustments.[3]In the second quarter of 2014, the company recognized a non-cash charge of $149 million for the impairment of certain intangible assets of our Brazilian engine reporting unit. Due to the economic downturn in Brazil which resulted in a continued decline in actual and forecasted results, we tested the goodwill of our Brazilian engine reporting unit and trademark for potential impairment. As a result, we determined that the entire $142 million balance of goodwill and $7 million of trademark were impaired. 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.[4](B)In the first quarter of 2013, we recognized $13 million of charges for adjustments to pre-existing warranties for a specific warranty issue related to component parts from a supplier. Also during the first quarter of 2013, we reached an agreement for reimbursement from this supplier for this amount and other costs previously accrued. As a result of this agreement, we recognized a recovery of $27 million within Costs of products sold and recorded a receivable within Other current assets. In the second quarter of 2013, we recognized a warranty recovery of $13 million within Income (loss) from discontinued operations, net of tax and recorded a receivable within Other current assets.In the third quarter of 2012, we recognized $10 million of adjustments to pre-existing warranties for a specific warranty issue related to component parts from a supplier. Also during the quarter, we reached agreement for reimbursement from such supplier and recognized a recovery for that amount and recorded a receivable within Other current assets.[5](A)Adjustments to pre-existing warranties reflect changes in our estimate of warranty costs for products sold in prior periods. Such adjustments typically occur when claims experience deviates from historic and expected trends. Our warranty liability is generally affected by component failure rates, repair costs, and the timing of failures. Future events and circumstances related to these factors could materially change our estimates and require adjustments to our liability. In addition, new product launches require a greater use of judgment in developing estimates until historical experience becomes available. In the first quarter of 2014, we recorded adjustments for changes in estimates of $52 million or $0.64 per diluted share. In the second quarter of 2014, we recorded adjustments for changes in estimates of $42 million, or $0.52 per diluted share. In the third quarter of 2014, we recognized a benefit for adjustments to pre-existing warranties of $(29) million, or $(0.36) per diluted share. Included in the 2014 adjustments is a $36 million correction of prior-period errors, primarily related to pre-existing warranties. For more information on the errors identified, see 2014 Out-of-Period Adjustments. The impact of income taxes on the 2014 adjustments is not material due to our deferred tax valuation allowances on our U.S. deferred tax assets.In the first quarter of 2013, we recorded adjustments for changes in estimates of $40 million or $0.50 per diluted share. In the second quarter of 2013, we recorded adjustments for changes in estimates of $164 million, or $2.04 per diluted share. In the third quarter of 2013, we recorded adjustments for changes in estimates of $48 million, or $0.60 per diluted share. In the fourth quarter of 2013, we recorded adjustments for changes in estimates of $152 million, or $1.89 per diluted share. The impact of income taxes on the 2013 adjustments is not material due to our deferred tax valuation allowances on our U.S. deferred tax assets. In the first quarter of 2012, we recorded adjustments for changes in estimates of $123 million, or $1.76 per diluted share. In the second quarter of 2012, we recorded adjustments for changes in estimates of $104 million, or $1.51 per diluted share. In the fourth quarter of 2012, we recorded adjustments for changes in estimates of $149 million, or $2.16 per diluted share.[6](A)For more information, see Note 8, Goodwill and Other Intangible Assets, Net, and includes $4 million related to discontinued operations in 2013. |
