Interest expense increased 2% in 2008 from 2007. The prior year included a $4 million reduction in interest related to the APA settlement. The remaining increase was due to a reduction in interest in 2007 related to the favorable settlement of U.S. federal income tax audits and lower capitalized interest, partially offset by lower debt
levels. Interest income declined to $8 million in 2008 from $19 million in 2007 primarily due to lower levels of cash and cash equivalents.
