Clean Harbors, Inc. (Norwell, MA), taking advantage of its stellar performance of late, has obtained a new credit facility that increases its borrowing capacity to $250 million while lowering its borrowing costs by 50 basis points. The new five-year revolving credit facility is an increase from a previous $120 million facility that was scheduled to mature in July 2013. It increases to $150 million the amount of borrowings which the Company and its U.S. subsidiaries may obtain and allows the Company's Canadian subsidiaries to obtain up to $100 million of borrowings to facilitate ongoing activities in Canada. The new agreement matures in 2016. "With increased borrowing capacity on more favorable terms, this credit facility greatly enhances our financial flexibility and ability to execute our corporate strategy," said Clean Harbors Chairman and Chief Executive Officer Alan S. McKim. "Coupled with the $250 million of senior secured notes we issued earlier this year, this credit agreement reflects the confidence of the lending community in our prospects for growth through acquisition and internal investments."
