       We have postretirement health care and life insurance plans that
       cover certain of our salaried and hourly employees who retire in
       accordance with the various provisions of such plans. Benefits
       may be subject to deductibles, copayments, and other
       limitations. These postretirement plans are not funded, and we
       reserve the right to change them. Interest cost of benefit
       obligations were $1&amp;#160;million for the three-month period and
       $2&amp;#160;million for the six-month period ended June&amp;#160;30,
       2010, and June&amp;#160;30, 2009. Interest cost of benefit
       obligations accounted for the total net periodic benefit expense
       for our postretirement plans.
