Rand Logistics Inc., one of the largest bulk-freight shipping companies in the Great Lakes region, has filed for bankruptcy protection after agreeing to a debt-for-equity swap with Lightship Capital LLC, WSJ Pro Bankruptcy reported. Rand, whose corporate headquarters are in Jersey City, N.J., said on Monday that the deal with junior lender Lightship will eliminate $92 million in debt from it books. The company blamed its financial woes, in part, on the weakness of the Canadian dollar versus the U.S. dollar. From 2014 to 2016, the Canadian dollar weakened against the U.S. dollar by approximately 30 percent, according to court papers.
