TMX Group and the London Stock Exchange Group have settled on LTMX Group plc as a name for the proposed transatlantic exchange operator.

The name, which will be adopted if the merger is approved by shareholders, was revealed in an information circular distributed to LSE Group shareholders.

The TMX Group says in its circular to shareholders that the new name was chosen to reflect the merged company's international profile.

The packages were sent out and filed with regulators in advance of a shareholder vote slated to be held June 30 at both operators.

The TMX Group is pushing ahead with the merger after rejecting an alternative proposal by a Canadian consortium of banks and pension funds.

The merger is subject to approval from various Canadian regulators, including a review under the Investment Canada Act.
