All derivative financial instruments are recognized on the condensed consolidated balance sheets at fair value.

The effect of derivative instruments not designed as hedging instruments on the accompanying condensed consolidated statements of operations was $0 [2011—gain of $129] for the six months ended June 30, 2012.
