TC PipeLines, LP to Release Fourth Quarter and Full Year 2015 Results on February 25

Expects Non-Cash Impairment Charge


HOUSTON, TEXAS--(Marketwired - Feb. 11, 2016) - TC PipeLines, LP (NYSE:TCP) (the Partnership) will release its fourth quarter and full year 2015 financial results on Thursday, February 25, 2016. Brandon Anderson, president of the general partner, will discuss the Partnership's financial results and latest developments in a teleconference and webcast on Thursday, February 25 at 10 a.m. (CDT)/ 11 a.m. (EDT).

The Partnership expects to record a non-cash impairment charge of approximately $199 million for the fourth quarter of 2015 related to its investment in Great Lakes Gas Transmission Limited Partnership. Despite the recent improvement in income from Great Lakes, its long-term value has been adversely impacted by changing natural gas flows in its market region as well as the infeasibility, in our view, of other strategic alternatives to increase its utilization or revenue. As a result, we determined that the carrying value of our investment in GLGT is in excess of its fair value, and that this decline is not temporary.

The preliminary estimate of the fourth quarter 2015 impairment charge related to the Partnership's investment in Great Lakes is based upon current information available to the Partnership's management personnel. The Partnership expects to include the actual amount of the impairment charge when it announces its fourth quarter and full-year 2015 financial results. The impairment charge is a one-time, non-cash item which does not impact our ability to generate distributable cash flow or to pay distributions to our unitholders.

Analysts, members of the media and other interested parties are invited to participate in the call by dialing 866.225.6564. Please dial in 10 minutes prior to the start of the call. No pass code is required. A live webcast will also be available through the Partnership's website at www.tcpipelineslp.com. Slides for the conference call will be posted on the Partnership's website under "Events and Presentations" prior to the webcast.

A replay of the teleconference will also be available two hours after the conclusion of the call and until 11 p.m. (CDT) and midnight (EDT) on March 3, 2016, by calling 800.408.3053, then entering pass code 9878635.
