At the end of the lease term, the acquired lease provided UOS with a purchase option permitting UOS to purchase both the Tug and Barge. Prior to the closing of the acquisition, UOS exercised the purchase option through a legally binding agreement. We acquired the lease agreement as part of the acquisition of UOS, including the binding purchase commitment, and were therefore obligated to purchase the unit. On September 25, 2013 we concluded the purchase of the Tug/Barge unit.
