(1) Derivative contracts address foreign exchange fluctuations for the Euro versus the U.S. Dollar.

(2) The fair value of our derivatives are not material for all periods presented and are reported as liabilities in accrued and other current liabilities on our unaudited consolidated balance sheets. We measure the fair value of our outstanding or unsettled derivatives using Level 2 fair value inputs, as we use a pricing model that takes into account the contract terms as well as current foreign currency exchange rates in active markets.
