Recent Business Developments

Cash Distributions - On October 24, 2017, the board of directors of our General Partner declared the Partnership's third quarter 2017 cash distribution in the amount of $1.00 per common unit payable on November 14, 2017 to unitholders of record as of November 3, 2017. The declared distribution will include a $2 million distribution to our General Partner for its effective two percent general partner interest and an incentive distribution rights (IDR) payment amounting to $3 million.

Great Lakes Contracting and Settlement - On April 24, 2017, Great Lakes reached an agreement on the terms of a new long-term transportation capacity contract with its affiliate, TransCanada. The contract, which was subject to Canada's National Energy Board (NEB) approval, is for a term of 10 years and allows TransCanada the ability to transport up to 0.711 billion cubic feet of natural gas per day on the Great Lakes system from the Manitoba/U.S. border to the U.S. border near Dawn Ontario. On September 21, 2017, TransCanada received approval from the NEB and as a result, this contract commenced on November 1, 2017. This contract contains volume reduction options up to full contract quantity beginning in year three.

On October 30, 2017, Great Lakes filed a rate settlement with FERC to satisfy its obligations from its 2013 rate settlement for new rates to be in effect by January 1, 2018 (2017 Great Lakes Settlement). The 2017 Great Lakes Settlement, if approved by FERC, will decrease Great Lakes' maximum transportation rates by 27 percent beginning October 1, 2017. Great Lakes expects that the impact from other changes, including: the recent long-term transportation contract with TransCanada as described above, other revenue opportunities on the system and the elimination of the revenue sharing mechanism with its customers, will more than offset the full year impact of the reduction in Great Lakes' rates beginning in 2018. The 2017 Great Lakes Settlement does not contain any moratorium and Great Lakes will be required to file for new rates no later than March 31, 2022, with new rates to be effective October 1, 2022.

Northern Border Rate Case- Northern Border and its shippers have been engaged in settlement discussions, and have recently agreed to a settlement-in-principle addressing all rate and service related issues raised during the settlement discussions. Northern Border plans to file a settlement agreement with FERC before the end of the year, reflecting the settlement-in-principle, precluding the need to file a general rate case as contemplated by its 2012 Settlement. Northern Border anticipates that the Commission will accept the settlement agreement and that it will be unopposed. This will provide Northern Border with rate stability over the longer term. At this time, we do not believe that the final outcome of the settlement will have a material impact to the Partnership's results. Northern Border remains a key competitive pipeline and continues to operate at full capacity connecting major supply basins with communities in the Midwestern U.S.

Portland XPress Project- PNGTS has executed Precedent Agreements with several Local Distribution Companies (LDCs) in New England and Atlantic Canada to re-contract certain system capacity set to expire in 2019 as well as expand the PNGTS system to bring its certificated capacity up to 0.3 Bcf/d. The approximately $80 million Portland XPress Project (PXP) will proceed concurrently with upstream capacity expansions. The in-service dates of PXP are being phased-in over a three-year period beginning November 1, 2018.

Results of Operations

For the three months ended September 30, 2017, our net income attributable to controlling interests was lower by $4 million compared to the prior period due to the net effect of lower revenues and overall higher costs that were partially offset by higher equity earnings.

  • Revenues were lower due to lower discretionary revenues on short-term services sold by PNGTS.
  • Increase in equity earnings was primarily due to the addition of equity earnings from Iroquois Gas Transmission System (Iroquois), resulting from the addition of Iroquois to our portfolio of assets effective June 1, 2017 partially offset by lower equity earnings from Northern Border and Great Lakes due to higher pipeline integrity program spending and other operating costs. The increase in pipeline integrity work at Great Lakes is in relation to the increase in natural gas flows which have been ramping up during the year.
  • The increase in our operating costs was mainly attributable to higher pipeline integrity on Gas Transmission Northwest LLC (GTN) and overall higher allocated management and operational expenses on our pipeline systems as performed by TransCanada.
  • Interest expense increased primarily due to the additional borrowings to finance the June 1, 2017 acquisition of a 49.34 percent interest in Iroquois and an additional 11.81 percent interest in PNGTS from subsidiaries of TransCanada.

Our overall EBITDA was comparable to the same period in 2016. The slight increase was the result of the addition of our equity interest in Iroquois effective June 1, 2017 offset by lower revenues and increase in our operating costs.

Distributable cash flow decreased by $4 million in the third quarter of 2017 compared to the same period in 2016 primarily due to the net effect of:

  • addition of our 49.34 percent share of Iroquois' third quarter 2017 distribution;
  • lower distributions from our equity investment in Great Lakes and Northern Border primarily due to their higher pipeline integrity and other operating costs
  • higher maintenance capital expenditures, the majority of which related to major compression equipment overhauls on GTN's pipeline system;
  • higher financing costs due to additional borrowings to finance our most recently completed acquisition;
  • higher incentive distributions declared to our General Partner during the current period; and
  • lower distributions allocable to the Class B units during the current period.

Cash Flow Analysis

Operating Cash Flows

Net cash provided by operating activities decreased by $21 million in the nine months ended September 30, 2017 compared to the same period in 2016 primarily due to lower distributions from Great Lakes and Northern Border in 2017 partially offset by distributions received from Iroquois, resulting from the addition of Iroquois to our portfolio of assets effective June 1, 2017. Distributions received in the first quarter of 2016 from Great Lakes were higher than on a run-rate basis due to the resolution of certain regulatory proceedings in the fourth quarter of 2015 which inflated its results during that period and resulted in higher cash flow which was paid to the Partnership in the first quarter of 2016 and not applicable in the first quarter of 2017. Additionally, the Partnership received lower distributions from Northern Border in the current period compared to the same period in 2016 primarily due to higher maintenance capital expenditures during the current 2017 period together with the change in Northern Border's distribution policy during 2016 from a lagged quarterly distribution to a more timely monthly distribution that resulted in a larger distribution in the third quarter of 2016.

Investing Cash Flows

Net cash used in investing activities increased by $541 million in the nine months ended September 30, 2017 compared to the same period in 2016. On January 1, 2016, we invested $193 million to acquire a 49.9 percent interest in PNGTS and on June 1, 2017, we invested $593 million to acquire a 49.34 percent interest in Iroquois and $53 million to acquire an additional 11.81 percent of PNGTS. During the nine months ended September 30, 2017 compared to 2016, we incurred higher maintenance capital expenditures related to major compression equipment overhauls on GTN's pipeline system and on September 1, 2017, we contributed $83 million to Northern Border representing our 50 percent share of a requested capital contribution to reduce the outstanding balance of its revolving credit facility.

Financing Cash Flows

The net change in cash from our financing activities was approximately $549 million in the nine months ended September 30, 2017 compared to the same period in 2016 primarily due to the net effect of:

  • $564 million increase in net issuances of debt in 2017 primarily to finance the June 1, 2017 acquisition of a 49.34 percent interest in Iroquois and an additional 11.81 percent interest in PNGTS from subsidiaries of TransCanada;
  • $8 million increase in our ATM equity issuances in 2017 as compared to 2016;
  • $26 million increase in distributions paid to our common units and to our General Partner in respect of its two percent general partner interest and IDRs;
  • $10 million increase in distributions paid to Class B units in 2017 as compared to 2016;
  • $7 million decrease in distributions paid to non-controlling interest due to lower revenues on PNGTS compared to the previous periods; and
  • $8 million decrease in distributions paid to TransCanada as the former parent of PNGTS primarily due to the Partnership's acquisition of a 49.9 percent interest in PNGTS effective January 1, 2016 and additional 11.81 percent effective June 1, 2017.

At September 30, 2017, the Partnership's available borrowing capacity under its $500 million credit facility was $245 million.

Non-GAAP Financial Measures

The following non-GAAP financial measures are presented as a supplement to our financial statements:

  • EBITDA
  • Total distributable cash flow
  • Distributable cash flow

EBITDA is an approximate measure of our operating cash flow during the current earnings period and reconciles directly to the net income amount presented. It measures our earnings before deducting interest, depreciation and amortization and net income attributable to non-controlling interests and includes earnings from our equity investments.

Total distributable cash flow and distributable cash flow provide measures of distributable cash generated during the current earnings period and reconcile directly to the net income amounts presented.

Total distributable cash flow includes EBITDA plus:

  • Distributions from our equity investments
    less:
  • Earnings from our equity investments,
  • Equity allowance for funds used during construction (Equity AFUDC),
  • Interest expense,
  • Distributions to non-controlling interests,
  • Distributions to TransCanada as the former parent of PNGTS and
  • Maintenance capital expenditures from consolidated subsidiaries.

Distributable cash flow is computed net of distributions declared to the General Partner and distributions allocable to Class B units. Distributions declared to the General Partner are based on its effective two percent interest plus an amount equal to incentive distributions. Distributions allocable to the Class B units equal 30 percent of GTN's distributable cash flow for the year ended December 31, 2017 less $20 million (2016 - less $20 million).

The non-GAAP financial measures described above are performance measures presented to assist investors in evaluating our business performance. We believe these measures provide additional meaningful information in evaluating our financial performance and cash generating capacity.

The non-GAAP financial measures presented as part of this release are provided as a supplement to GAAP financial results and are not meant to be considered in isolation or as substitutes for financial information prepared in accordance with GAAP. Additionally, these measures as presented may not be comparable to similarly titled measures of other companies.

For a reconciliation of these non-GAAP financial measures to GAAP measures, please see the table captioned "Reconciliation of Net income to Distributable Cash Flow" included at the end of this release.

(a) Financial information was recast to consolidate PNGTS for all periods presented. For more information, refer to our Quarterly Report on Form 10-Q for the period ended September 30, 2017, as filed with the SEC. Prior to the recast associated with the 2017 Acquisition, our net income attributable to controlling interests was $58 million and $185 million for the three and nine months ended September 30, 2016, respectively, reflecting our 49.9 percent ownership in PNGTS. After the recast, net income attributable to controlling interests was $58 million and $188 million for the three and nine months ended September 30, 2016, respectively, reflecting our 61.7 percent ownership in PNGTS. Net income attributable to PNGTS' former parent of $nil million and $3 million, reflecting the 11.81 percent interest not then owned by the Partnership, for the three and nine months ended September 30, 2016, respectively, reconciles the net income as previously reported with that after the recast.
(b) Net income per common unit is computed by dividing net income attributable to controlling interests, after deduction of amounts attributable to PNGTS' former parent, amounts attributable to the General Partner and Class B units, by the weighted average number of common units outstanding. The amount allocable to the General Partner equals an amount based upon the General Partner's effective two percent general partner interest, plus an amount equal to incentive distribution rights. For the year ended December 31, 2017, the amount allocable to the Class B units is equal to 30 percent of GTN's annual distributable cash flow, less the threshold amount of $20 million (2016 - $20 million).During the three and nine months ended September 30, 2017, the amount allocated to the Class B units was $8 million. During the three and nine months ended September 30, 2016 the amount allocated to the Class B units was $11 and 12 million, respectively,

(a) Financial information was recast to consolidate PNGTS for all periods presented. For more information refer to our Quarterly Report on Form 10-Q for the period ended September 30, 2017, as filed with the SEC.
(b) In connection with the late filing of an employee-related Form 8-K with the SEC, we may have been ineligible to use the then-effective shelf registration statement upon the filing of our 2015 Form 10-K. As a result, it was determined that the 1.6 million common units that were issued from March 8, 2016 to May 19, 2016, inclusive, under our ATM program may have had a rescission right for an amount equal to the purchase price paid for the units, plus statutory interest and less any distributions paid, upon the return of the units to us. The rescission rights related to these units expired approximately one year from the date of purchase of the units.
At December 31, 2016, $83 million was recorded as common units subject to rescission on the consolidated balance sheet. This represents all of the 1.6 million common units sold under the ATM program from March 8, 2016 to May 19, 2016, inclusive, which may have been subject to rescission rights. The separation on the balance sheet placed these units outside of equity given the potential redemption feature which was not within the control of the Partnership.
No unitholder claimed or attempted to exercise any rescission rights prior to their expiry dates and the final rights related to the sales of such units expired on May 19, 2017. As a result of the expiration of these rights, the $83 million was reclassified back to partners' equity. At September 30,2017, there were no outstanding common units subject to rescission on the Partnership's consolidated balance sheet.
For more information, refer to our Quarterly Report on Form 10-Q for the period ended September 30, 2017 as filed with the SEC.

(b) In August 2016, the Financial Accounting Standards Board issued Accounting Standards Update No. 2016-15 "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments," an amendment of previously issued guidance, which intends to reduce diversity in practice as to how certain transactions are classified in the statement of cash flows. The new guidance is effective January 1, 2018, however as early adoption is permitted, the Partnership elected to retrospectively apply this guidance effective December 31, 2016. The Partnership has elected to classify distributions received from equity method investees using the nature of distributions approach as it is more representative of the nature of the underlying activities of the investees that generated the distributions. As a result, certain comparative period distributions, received from equity method investees, amounting to $50 million for the nine months ended September 30, 2016 have been reclassified from investing activities to cash generated from operations in the consolidated statement of cash flows.
