CY2014	us-gaap	Description Of Reclassification Of Cash Flow Hedge Gain Loss DescriptionOfReclassificationOfCashFlowHedgeGainLoss	When a cash flow hedging relationship is discontinued, the net gain or loss in AOCI must generally remain in AOCI until the item that was hedged affects earnings. However, when it is probable that a forecasted transaction will not occur by the end of the originally specified time period or within an additional two-month period thereafter, the net gain or loss in AOCI must be reclassified into earnings immediately.
