Toronto-based TMX Group Ltd. announced Thursday it has completed an asset swap with Atlanta-based Intercontinental Exchange, Inc. (ICE) by which TMX acquires London, U.K.-based Trayport Holdings Ltd. in exchange for TMX subsidiaries Natural Gas Exchange Inc. (NGX), Shorcan Energy Brokers Inc.

The transaction was first announced in October 2017.

The U.K. Competition and Markets Authority approved the sale of Trayport, which provides technology solutions for energy traders, brokers and exchanges, TMX says in its announcement, and the U.K. Commissioner of Competition issued a “no action” letter regarding the sale of NGX and Shorcan Energy to ICE.

“The addition of NGX’s products and clearing services offers our customers an expanded range of energy products and risk management solutions across physical and financially-settled markets,” says Ben Jackson, president of ICE, in a statement. “Shorcan’s brokerage business complements our global oil complex, which includes deep liquidity on the leading trading platform for oil markets.”

TMX paid a total consideration of $931 million for Trayport Holdings and Trayport Inc., its U.S.-based affiliate. The payment included $592 million in cash as well as the sale NGX and Shorcan Energy to ICE.

The cash portion of the deal is being funded through a debt offering by TMX, which closed on Dec. 11, along with cash on hand, and borrowing under the firm’s commercial paper program.
