(a)	Recast as discussed in Note 2 and Note 6.
(b)	Net income allocable to General and Limited Partners excludes net income attributed to GTN's and Bison's former parent as it was allocated to TransCanada and was not allocable to either the general partner, common units or Class B units (refer to Note 6 – 2013 Acquisition).
(c)	Net income allocable to General and Limited Partners is allocated based on their respective participation rights, after giving effect to any priority income allocation for incentive distributions that are allocated 100 percent to the General Partner. Under the terms of the Partnership Agreement, for any quarterly period, the participation of the IDRs is limited to the available cash distributions declared. Accordingly, incentive distributions allocated to the General Partner was based from the Partnership's available cash during the current reporting period, but declared and paid in the subsequent reporting period.
(d)	As discussed in Notes 6 and 9, the Class B units entitle TransCanada to a distribution which is an amount based on 30 percent of GTN's distributions after achieving certain annual thresholds. The distribution will be payable in the first quarter with respect to the prior year's distributions. Consistent with the application of Accounting Standards Codification (ASC) Topic 260 – "Earnings per share," the Partnership allocated a portion of net income attributable to controlling interests to the Class B units upon 30 percent of GTN's total distributable cash flows exceeding $15 million for the nine month period ended December 31, 2015. During the nine months ended December 31, 2015, 30 percent of GTN's total distributable cash flow was $27 million. As a result, $12 million of net income attributable to controlling interests was allocated to the Class B units in 2015. On February 12, 2016, this amount was paid to TransCanada (Refer to Note 13 and 22).
