(1)	The fair value of the derivative contracts is calculated as follows:


a.	Fair value of a put option contract associated with forecasted sales hedges is calculated using bid and ask rates for similar contracts.


b.	Fair value of regular forward contracts associated with forecasted sales hedges is calculated using the period-end exchange rate adjusted for current forward points.

Fair value of hedges against net assets is calculated at the period-end exchange rate adjusted for current forward points unless the hedge has been traded but not settled at period end (Level 2). If this is the case, the fair value is calculated at the rate at which the hedge is being settled (Level 1). As a result, there were $1 million of transfers from Level 2 to Level 1 as of June 30, 2018 and $2 million as of December 31, 2017.


(2)	The fair value of forward interest rate swaps is based upon a valuation model that uses relevant observable market inputs at the quoted intervals, such as forward yield curves, and is adjusted for the Company’s credit risk and the interest rate swap terms. See gross balance reporting in Note 7, Derivative Instruments.
