TMX Group Supportive of OSC Emerging Markets Issuer Review

March 20, 2012

Parallel consultations conducted by TMX Group will lead to enhancement of guidelines for emerging markets issuers

March 20, 2012 (TORONTO) – TMX Group today announced that it is supportive of the Ontario Securities Commission's Emerging Markets Issuer Review (OSC Review) and welcomes the publication of its report.

In parallel with TMX Group's co-operation with the OSC Review, Toronto Stock Exchange and TSX Venture Exchange initiated extensive consultations with market participants, publicly-listed companies and other stakeholders over the last several months. Following this review and industry consultation, TMX Group prepared and will soon provide additional guidance to emerging markets issuers. This guidance will complement existing rules and working practices, pending regulatory consultation and review by securities commissions, as applicable. Areas of focus will include additional detail regarding senior management and director qualifications, corporate governance matters, and disclosure and financial reporting expectations.

Kevan Cowan, President, TSX Markets and Group Head of Equities, TMX, said:

“While provincial securities regulators are the primary authority overseeing reporting issuers, TMX Group takes its responsibility and public interest mandate very seriously. With the growth of emerging market economies, issuers and investors from these markets are expected to increasingly seek opportunity in Canada and other developed economies around the world. The work currently being conducted by TMX Group is part of our ongoing efforts to enhance the quality and integrity of Canada's capital markets, a key competitive advantage both for us and for Canada.”

The OSC Review noted the inter-connected responsibility of a broad group of stakeholders in ensuring investor confidence in Canada's markets, including reporting issuer management and directors, auditors, underwriters and other legal and financial professionals. TMX Group's equity exchanges contribute to this oversight through well-established guidelines and standards and by enforcing issuer rules and standards that promote a quality market.
