(1) During the nine months ended September 30, 2012, our recommended remediation plan for one of the hurricane damaged platforms and its associated wells was approved by all required parties. The approved plan, which included remediating the damaged platform as a reef in place, was responsible for most of the reduction of the estimated costs.
(2) The majority of the increase is attributable to properties that we do not operate.
