Cash flow hedge gain (loss) to be reclassified from AOCI into income/(expense) within twelve months	$ 2

[1] Over the next 12 months, deferred gains totaling $2 million are expected to be reclassified from AOCI on our Condensed Consolidated Balance Sheets into the expense line item on our Condensed Consolidated Statements of Operations that is consistent with the nature of the underlying hedged item as the forecasted transactions occur.

[2] The amount of ineffectiveness associated with these hedging instruments was not material.

[3] The gain (loss) recognized on these currency contracts is offset by the gain (loss) recognized on the remeasurement of the underlying debt instruments; therefore, there is a minimal consolidated net effect in other nonoperating expense, net on our Condensed Consolidated Statements of Operations.
