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. Inthe 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 2014Out-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.Inthe 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.  (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.
