As a result of the divestiture of Styron on June 17, 2010, the Company recognized a curtailment loss of $11 million and improved the funded status (plan assets less benefit obligations) by $99 million due to settlements, remeasurements and curtailments (see Note D).

The Company's funding policy is to contribute to its pension plans when pension laws and/or economics either require or encourage funding. In the nine-month period ended September 30, 2011, the Company contributed $712 million to its pension plans, including contributions to fund benefit payments for its non-qualified supplemental plans. The Company expects to contribute approximately $200 million to its pension plans in the fourth quarter of 2011.
