In January 2013, ArcelorMittal bid $1.5 billion to acquire ThyssenKrupp AG's rolling mill in Calvert, Alabama, United States. On 26 February 2014, ThyssenKrupp sold their Calvert carbon steel facility to ArcelorMittal and Nippon Steel for $1.55 billion, as a new joint venture. The facility was renamed AM/NS Calvert through the 50/50 joint partnership with Nippon Steel & Sumitomo Metal Corp. The firm also entered into a $2.2 billion contract to develop an iron ore deposit in Senegal. This included construction of a railway line. After it stalled on the contract and failed to build according to schedule, the Government of Senegal sued. In September 2013, the government of Senegal won a court case before an international tribunal to rescind a $2.2 billion deal with ArcelorMittal after the company suspended work on an iron ore mine in the country. In June 2014, the International Chamber of Commerce's arbitration court in Paris awarded Senegal $150 million.
