Companies reporting major news:

Rogers Communications Inc. (TSX:RCI.B). Communication services. Up one cent, or 0.02 per cent, to $44.28 on 460,272 shares. The Toronto-based telecommunications and media company, reporting after markets closed, said its adjusted income was 66 cents per share, four cents below the average estimate of 70 cents per share, according to a survey by Thomson Reuters. Operating revenues were relatively steady at $3.02 billion, marginally below the $3.03 billion reported in the comparable year-earlier period.

Smart Technologies Inc. (TSX:SMA). Computer hardware. Down 38 cents, or 7.74 per cent, to $4.53 on 75,065 shares. The company, a developer of electronic white boards used for education and business applications, says co-founders David Martin and Nancy Knowlton have resigned from the board of directors — triggering the end of the company's multiple-voting shares.

TransCanada Corp. (TSX:TRP). Oil and gas. Down $1.92, or 3.74 per cent, to $49.38 on 2.8 million shares. The company says its customers are still "100 per cent" behind its proposed Keystone XL oil pipeline, despite dimming prospects that shovels will be hitting the ground any time soon. Late last week the U.S. State Department said it was extending indefinitely the amount of time that federal agencies have to review the $5.4-billion project, likely delaying a pipeline decision until after the November elections.
