Chemical giant DuPont Co has agreed to lower the sale price of its Invista clothing and carpet fibre business by $200 million to $4.2 billion.

The Delaware-based company added that the sale of Invista to Koch Industries Inc, scheduled for June 30, would close two months earlier on April 30.

Last November, the company agreed to sell the business for $4.4bn in cash, less than the reported $5.5bn it had hoped for.
