These forward contracts are designated as fair value hedges and are highly effective. We recognize the fair value of our derivative asset as a Level 2 valuation. The fair value at June 30, 2013 was $0.5 million. We determined the fair value based on the contractual rate in each forward agreement and compared the contractual rate to the forward rate as provided by our counterparty as of June 30, 2013. The following table presents information about our assets (liabilities) measured at fair value on a recurring basis as of June 30, 2013, and indicates the fair value hierarchy we utilized to determine such fair value (in millions). <table id="TBL4228" style="FONT-SIZE: 10pt;
