Nova Chemicals said first-quarter profit slipped by 1.6 percent mainly because of finance costs associated with paying down its debt.
Profit was $185 million, down from $188 million in the first quarter of 2012.
Revenues for the producer of plastics resins and chemicals fell slightly to $1.25 billion from $1.34 billion a year ago.
Nova, based in Calgary, Canada, has an executive operations center in Moon and a plant in Monaca, Beaver County. The company is owned by International Petroleum Investment Co. of the United Arab Emirates.
