(a) Prior service credits increased by $0 million, $30 million and $0 million and actuarial losses increased by approximately $306 million, $560 million and $78 million for 2017, 2016 and 2015, respectively. (b) This amount represents the reclassification from AOCI to RE of the stranded tax effects resulting from the enactment of the Tax Act. (c) Deferred tax balance relates mainly to Pension and Other Postretirement Liabilities. (d) The last of the Company’s fuel hedge derivatives designated for cash flow hedge accounting expired in December 2016. The 2017 amount reclassified from AOCI into fuel expense represents hedge losses on December 2016 settled trades, but for which the associated fuel purchased in December 2016 was not consumed until January 2017. The Company’s current strategy is to not enter into transactions to hedge its fuel consumption, although the Company regularly reviews its strategy based on market conditions and other factors. (e) This AOCI component is included in the computation of net periodic pension and other postretirement costs (see Note 8 of this report for additional information). Prior to the release of the deferred income tax valuation allowance in the third quarter of 2015, the Company recorded approximately $465 million of valuation allowance adjustments in AOCI. Subsequent to the release of the deferred income tax valuation allowance in 2015, the $465 million debit remained within AOCI, of which $180 million related to losses on fuel hedges designated for hedge accounting and $285 million related to pension and other postretirement liabilities. Accounting rules required the adjustments to remain in AOCI as long as the Company had fuel derivatives designated for cash flow hedge accounting and the Company continues to provide pension and postretirement benefits. In 2016, the Company settled all of its fuel hedges and has not entered into any new fuel derivative contracts for hedge accounting. Accordingly, the Company reclassified the $180 million to income tax expense in 2016.
