Dow Chemical Co. (DOW) will close three Louisiana plants that produce ethylene and related products while cutting outside purchases of the chemical amid lower internal demand due to last year's restructuring plan.

The company's board approved the latest restructuring, which is expected to produce $100 million a year in cost savings and is part of the chemical giant's goal of cutting annual costs $1.3 billion amid its $16.3 billion acquisition of Rohm & Haas in April.

"Today's steps demonstrate our speed and determination to deliver these savings," said Chairman and Chief Executive Andrew N. Liveris.

The latest closing are in addition to shutdowns announced last year of four production units, located in Lousiana and Texas, which use ethylene and related products. The moves cut Gulf Coast demand 30%. The company also expects to end purchases of about 3 billion pound a year of ethylene from the merchant market.

The chemical sector was hit by a steep drop in demand late last year that resulting in production cuts, plant closings layoffs and even some bankruptcy filings.

Shares closed at $16.14 on Tuesday and didn't trade premarket. The stock has lost nearly 60% of its value in the past 9 1/2 months, though its has nearly tripled since hitting a low of $5.89 in March.
