The decrease in net income was largely due to lower revenue from issuer services and cash markets trading, partially offset by higher revenue from derivatives markets trading and clearing as well as higher information services revenue.

The total revenue for the fourth quarter of 2011 declined 7% to C$161.7m, compared to C$174.1m for the same period a year ago.

Issuer services revenue declined 17% to C$53.9m, compared to C$64.7m for the same period in the last year.

Trading, clearing and related revenue dropped 7% to C$62.1m, compared to C$66.7m for the same period in the previous year.

TMX Group CEO Thomas Kloet said that despite uncertainty in the global economy, they attracted an increased number of new issuers to their equity markets compared to 2010 and continue to provide an attractive venue for raising capital.
