Equity Investment We owned a 45% equity interest in MWL, a third-party provider of logistics services to the transportation industry, until October 31, 2019, at which time we sold our entire membership interest for approximately $1.3 million. Prior to the sale of our interest, a non-related party owned the other 55% equity interest in MWL. We accounted for our ownership interest in MWL under the equity method of accounting.
