[1] On June 30, 2010, we completed the sale of our Argentina operations.

[2] Included in the balance are benefit obligations related to both the executive deferred compensation plan and the directors’ health and medical plan.

[3] We canceled our Sugarcane Bay project in April 2010. The continuing costs relate to the cost to terminate the project and costs to restore the site to its original state. In April 2011, we agreed to resolve our litigation in regards to issues related to the cancellation of our Sugarcane Bay project. We expect to incur no additional material cash costs as a result of the settlement.
