Equity Method Investments and Joint Ventures [Abstract] |
Investments | Investments Investment in Mastery Logistics Systems, Inc. In 2020, we entered into a strategic partnership with Mastery Logistics Systems, Inc. (“MLSI”), a transportation technology development company. We are collaborating with MLSI to develop a cloud-based transportation management system using MLSI's SaaS technology which we have agreed to license. In 2020, we paid MLSI $5.0 million for shares of preferred stock of MLSI which represent approximately 5% ownership. This investment is being accounted for under ASC 321, Investments - Equity Securities and is recorded in other noncurrent assets on the consolidated balance sheet. As of March 31, 2021, no events have occurred that would indicate that the value of our investment in MLSI has changed. Investment in TuSimple On January 8, 2021, we made a $5.0 million equity investment in TuSimple, an autonomous trucking technology company. Our interest, which represents less than 1%, is being accounted for under ASC 321, Investments - Equity Securities and is recorded in other noncurrent assets on the consolidated balance sheet. As of March 31, 2021, no events have occurred that would indicate that the value of our investment in TuSimple has changed. Subsequent Event TuSimple completed its initial public offering in April 2021. Upon completion, our equity investment was converted to Class A common shares. We will record future changes in the value of our investment, based on the share price reported by Nasdaq, in other expense (income) on the consolidated statements of income.
