FORWARD-LOOKING STATEMENTS AND CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

This report includes certain forward-looking statements. Forward-looking statements are identified by words and phrases such as: “anticipate,” “assume,“ “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” “forecast,” “should,” “predict,” “could,” “will,” “may,” and other terms and expressions of similar meaning. The absence of these words, however, does not mean that the statements are not forward-looking. These statements are based on management’s beliefs and assumptions and on currently available information and include, but are not limited to, statements regarding anticipated financial performance, future capital expenditures, liquidity, market or competitive conditions, regulations, organic or strategic growth opportunities, contract renewals and ability to market open capacity, business prospects, outcome of regulatory proceedings and cash distributions to unitholders.

Forward-looking statements involve risks and uncertainties that may cause actual results to differ materially from the results predicted. These risks and uncertainties include, among other things, factors like various risks and uncertainties associated with the current extraordinary market environment and impacts resulting from the Coronavirus 2019 (COVID-19) pandemic and market disruptions relating to global supply and demand for oil and natural gas.
Factors that could cause actual results and our financial condition to differ materially from those contemplated in forward-looking statements include, but are not limited to:

·

the ability of our pipeline systems to sell available capacity on favorable terms and renew expiring contracts which are affected by, among other factors:

·

demand for natural gas;

·

changes in relative cost structures and production levels of natural gas producing basins;

·

natural gas prices and regional differences;

·

weather conditions;

·

availability and location of natural gas supplies in Canada and the United States (U.S.) in relation to our pipeline systems;

·

competition from other pipeline systems;

·

natural gas storage levels; and

·

rates and terms of service;

the outcome and frequency of rate proceedings or settlement negotiations on our pipeline systems;

·

other potential changes in the taxation of master limited partnershipspartnership (MLP) investments by state or federal governments such as final adoption of proposed regulations narrowing the sources of income qualifying for partnership tax treatment or the elimination of pass-through taxation or tax deferred distributions;

·

increases in operational or compliance costs resulting from changes in laws and governmental regulations affecting our pipeline systems, particularly regulations issued by the Federal Energy Regulatory Commission (FERC), the U.S. Environmental Protection Agency (EPA) and U.S. Department of Transportation (DOT);

·                  the impact of downward changes in oil and natural gas prices, including the effects on the creditworthiness of our shippers;

·

our ongoing ability to grow distributions through acquisitions, accretive expansions or other growth opportunities, including the timing, termsstructure and closure of futurefurther potential acquisitions;

·

potential conflicts of interest between TC PipeLines GP, Inc., our general partner (General Partner), TransCanadaTC Energy Corporation (TransCanada) and us;

the impact of a potential slowdown in construction activities or a delay in the completion of our capital projects including increases in costs and availability of labor, equipment and materials;
the impact of downward changes in oil and natural gas prices, including any effects on the creditworthiness of our shippers or the availability of associated gas in low oil price environment;
the impact of litigation and other opposition proceedings on our ability to begin work on projects and the potential impact of an ultimate court or administrative ruling to a project schedule or viability;
uncertainty surrounding the impact of global health crises that reduce commercial and economic activity, including the COVID-19 pandemic, on our business;
the impact of TC Energy's proposed acquisition of all the Partnership's outstanding common units not beneficially owned by TC Energy; and
the negotiation and execution, and the terms and conditions, of a definitive agreement relating to TC Energy’s offer to acquire the Partnership’s outstanding common units and the timing and ability of TC Energy or the Partnership to enter into or consummate such agreement.

These are not the only factors that could cause actual results to differ materially from those expressed or implied in any forward-looking statement. Other factors described elsewhere in this document, or factors that are unknown or unpredictable, could also have material adverse effects on future results. These and other risks are described in greater detail in Part II, Item 1A. “Risk Factors” of this report and in Part I, Item 1A. “Risk Factors”of our Annual Report on Form 10-K for the year ended December 31, 20162019 (2019 Annual Report) as filed with the SECSecurities and Exchange Commission (SEC) on February 28, 2017.21, 2020.

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1ORGANIZATION

TC PipeLines, LP and its subsidiaries are collectively referred to herein as the Partnership. The Partnership was formed by TransCanada PipeLines Limited, a wholly owned subsidiary of TransCanadaTC Energy Corporation (TransCanada(TC Energy Corporation together with its subsidiaries collectively referred to herein as TransCanada)TC Energy), to acquire, own and participate in the management of energy infrastructure assets in North America.

The Partnership owns its pipeline assets through three intermediate limited partnerships (ILPs), TC GL Intermediate Limited Partnership, TC PipeLines Intermediate Limited Partnership and TC Tuscarora Intermediate Limited Partnership.


NOTE 2SIGNIFICANT ACCOUNTING POLICIES

The accompanying consolidated financial statements and related notes have been prepared in accordance with United States generally accepted accounting principles (GAAP) and amounts are stated in U.S. dollars. The results of operations for the three and nine months ended September 30, 20172020 and 20162019 are not necessarily indicative of the results that may be expected for the full fiscal year.

The accompanying consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 20162019 included as exhibit 99.2 in our Current Report on Form 8-K dated August 3, 2017.2019 Annual Report. That report contains a more comprehensive summary of the Partnership’s significant accounting policies. In the opinion of management, the accompanying consolidated financial statements contain all of the appropriate adjustments, all of which are normally recurring adjustments unless otherwise noted, and considered necessary to present fairly the financial position of the Partnership, the results of operations and cash flows for the respective periods. Our significant accounting policies are consistent with those disclosed in our audited financial statements and notes thereto for the year ended December 31, 2016 included as exhibit 99.22019 Annual Report, except those that became effective in our Current Report on Form 8-K dated August 3, 2017, except2020 as described in full under Note 3, Accounting"Accounting Pronouncements.

"

Basis of Presentation

The Partnership consolidates its interests in entities over which it is able to exercise control. To the extent there are interests owned by other parties, these interests are included inas non-controlling interests. The Partnership uses the equity method of accounting for its investments in entities over which it is able to exercise significant influence.

Acquisitions by

U.S. federal and certain state income taxes are the Partnershipresponsibility of the limited partners and are not reflected in these consolidated financial statements. The tax effect of the Partnership's activities accrues to its limited partners. The Partnership’s taxable income or loss, which may vary substantially from TransCanada are considered common control transactions. When businesses are acquired from TransCanada that will be consolidated by the Partnership, the historical financial statements are required to be recast, except net income per common unit, to include the acquired entities for all periods presented.

When the Partnership acquires an asset or an investment from TransCanada, which will be accounted for by the equity method, the financial information is not required to be recast and the transaction is accounted for prospectively from the date of the acquisition.

On June 1, 2017, the Partnership acquired from a subsidiary of TransCanada an additional 11.81 percent interest in PNGTS, that resultedloss reported in the Partnership owning a 61.71 percent interestconsolidated statement of operations, is includable in PNGTS (Refer to Note 6).  As a resultthe U.S. federal income tax returns of the Partnership owning 61.71 percent interest in PNGTS, the Partnership’s historical financial information has been recast, except net income (loss) per common unit, to consolidate PNGTS for all the periods presented ineach partner.

In instances where the Partnership’s consolidated financial statements. Additionally, this acquisition was accountedentities are subject to state income taxes, the asset-liability method is used to account for as transaction between entities under common control, similar to poolingtaxes. This method requires recognition of interests, whereby thedeferred tax assets and liabilities for future tax consequences attributable to the differences between the financial statement carrying amount of PNGTS were recorded at TransCanada’s carrying value.

Also,existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are classified as non-current on June 1, 2017, the Partnership acquired from subsidiaries of TransCanada a 49.34 percent interest in Iroquois Gas Transmission, L.P. (“Iroquois”) (Refer to Note 6). Accordingly, this transaction was accounted for as a transaction between entities under common control, similar to pooling of interest, whereby the equity investment in Iroquois was recorded at TransCanada’s carrying value and was accounted for prospectively.

our consolidated balance sheets.

Use of Estimates

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities, if any, as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Although management believes these estimates are reasonable, actual results could differ from these estimates.

NOTE 3ACCOUNTING PRONOUNCEMENTS

Retrospective application

Changes in Accounting Policies effective January 1, 2020
Measurement of Accounting Standards Update (ASU) No 2016-15 Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments”

credit losses on financial instruments

In AugustJune 2016, the Financial Accounting Standards Board (FASB) issued an amendment of previously issuednew guidance which intends to reduce diversity in practice inthat changes how entities measure credit losses for most financial assets and certain transactionsother financial instruments that are classified in the statement of cash flows.not measured at fair value through net income (loss). The new guidance isamends the impairment model of financial instruments basing it on expected losses rather than incurred losses. These expected credit losses will be recognized as an allowance rather than as a direct write down of the amortized cost basis. The new guidance became 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.

Effective January 1, 2017

Inventory

In July 2015, the FASB issued new guidance on simplifying the measurement of inventory. The new guidance specifies that an entity should measure inventory within the scope of this update at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This new guidance was effective January 1, 2017, was applied prospectively and did not have a material impact on the Partnership’s consolidated balance sheet.

Equity method and joint ventures

In March 2016, the FASB issued new guidance that simplifies the transition to equity method accounting. The new guidance eliminates the requirement to retroactively apply the equity method of accounting when an increase in ownership interest in an investment qualifies for equity method accounting. The new guidance is effective January 1, 20172020 and was applied prospectively.using a modified retrospective approach. The applicationadoption of this new guidance did not have a material impact on the Partnership’s consolidated financial statements.

Consolidation

In October 2016,2018, the FASB issued new guidance on consolidation relatingfor determining whether fees paid to decision makers and service providers are variable interests for indirect interests held through related parties that are under common control. The new guidance amends the consolidation requirements such that if a decision maker is required to evaluate whether it is the primary beneficiary of a variable interest entry (VIE), it will need to consider only its proportionate indirect interest in the VIE held through a common control party.  The guidance was effective January 1, 2017, was applied retrospectively and did not result in any change to our consolidation conclusions.

Future accounting changes

Revenue from contracts with customers

In 2014, the FASB issued new guidance on revenue from contracts with customers. The new guidance requires that an entity recognize revenue in accordance with a prescribed model. This model is used to depict the transfer of promised goods or services to customers in an amount that reflects the total consideration to which it expects to be entitled during the term of the contract in exchange for those goods or services. The new guidance also requires additional disclosures about the nature, amount, timing and uncertainty of revenue and the related cash flows. The Partnership will adopt the new standard on the effective date of January 1, 2018. There are two methods in which the new standard can be adopted: (1) a full retrospective approach with restatement of all prior periods presented, or (2) a modified retrospective approach with a cumulative-effect adjustment as of the date of adoption. The Partnership will adopt the

standard using the modified retrospective approach with the cumulative-effect of the adjustment recognized at the date of adoption, subject to allowable and elected practical expedients.

The Partnership has identified all existing customer contracts that are within the scope of the new guidance and is on schedule in the process of analyzing individual contracts or groups of contracts to identify any significant changes in how revenues are recognized as a result of implementing the new guidance. While the Partnership has not identified any material differences in the amount and timing of revenue recognition for the contracts that have been analyzed to date, the evaluation is not complete and the Partnership has not concluded on the overall impact of adopting the new guidance. The Partnership continues its contract analysis to obtain the information necessary to quantify the cumulative-effect adjustment, if any, on prior period revenues and revenue recognized going forward.

Although consolidated revenues may not be materially impacted by the new guidance, the Partnership currently anticipates significant changes to disclosures based on the additional requirements prescribed. These new disclosures include information regarding the significant judgments used in evaluating when and how revenue is recognized and information related to contract assets and liabilities. In addition, the new guidance requires that the Partnership’s revenue recognition policy disclosure includes additional detail regarding the various performance obligations and the nature, amount, timing and estimates of revenue and cash flows generated from contracts with customers. The Partnership continues to develop and evaluate disclosures required with a particular focus on the scope of contracts subject to disclosure of remaining performance obligations. The Partnership also continues to address any system and process changes necessary to compile the information to meet the recognition and disclosure requirements of the new guidance. The Partnership continues to monitor additional authoritative or interpretive guidance related to the new guidance as it becomes available.

Leases

In February 2016, the FASB issued new guidance on the accounting for leases. The new guidance amends the definition of a lease requiring the customer to have both (1) the right to obtain substantially all of the economic benefits from the use of the asset and (2) the right to direct the use of the asset in order for the arrangement to qualify as a lease. The new guidance also establishes a right-of-use (ROU) model that requires a lessee to recognize a ROU asset and corresponding lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The new guidance does not make extensive changes to lessor accounting.

The new guidance is effective on January 1, 2019, with early adoption permitted. A modified retrospective transition approach is required for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Partnership is continuing to identify and analyze existing lease agreements to determine the effect of adoption of the new guidance on its consolidated financial statements. The Partnership is also addressing system and process changes necessary to compile the information to meet the recognition and disclosure requirements of the new guidance.

Goodwill Impairment

In January 2017, the FASB issued new guidance on simplifying the test for goodwill impairment by eliminating the requirement to calculate the implied fair value of goodwill to measure the impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. This new guidance isbecame effective January 1, 2020, and will bewas applied prospectively. Early adoption is permitted.on a retrospective basis. The Partnership is currently evaluating the impact of the adoption of this new guidance and hasdid not yet determinedhave a material impact on the effect on itsPartnership’s consolidated financial statements.

Hedge Accounting


Reference rate reform
In August 2017,March 2020, in response to the expected cessation of LIBOR, the FASB issued new optional guidance on hedgethat eases the potential burden of accounting making more financial and nonfinancial hedging strategies eligible for hedge accounting.reference rate reform. The new guidance amendsprovides optional expedients for contracts and hedging relationships that are affected by reference rate reform, if certain criteria are met. Each of the presentation requirements relatingexpedients can be applied as of January 1, 2020 through December 31, 2022. For eligible hedging relationships existing as of January 1, 2020 and prospectively, the Partnership has applied the optional expedient allowing an entity to assume that the hedged forecasted transaction in a cash flow hedge is probable of occurring. As reference rate reform is still an ongoing process, the Partnership will continue to evaluate the timing and potential impact of adoption of other optional expedients when deemed necessary.

NOTE 4GOODWILL
Under U.S. GAAP, we evaluate our goodwill related to Tuscarora and North Baja for impairment at least annually and if any indicators of impairment are evident.
In 2019, based on our analysis of Tuscarora and North Baja’s current market conditions, we believed there was a greater than 50 percent likelihood that Tuscarora and North Baja’s estimated fair value exceeded their carrying value. As a result, at December 31, 2019, we did not identify an impairment on the $71 million of goodwill related to the changeTuscarora ($23 million) and North Baja ($48 million) reporting units.
On March 11, 2020, the World Health Organization (WHO) declared COVID-19 a global pandemic. While there are continuing concerns around the decline in fair valueenergy demand related to the pandemic, we believe the current state of the macroeconomic environment does not represent a derivative and additional disclosure requirements include cumulative basis adjustments for fair value hedges andpermanent shift. However, it remains difficult to predict with any certainty the effectseverity of hedging on individual statement of income line items. This new guidance is effective January 1, 2019 and will be applied prospectively with a cumulative-effect adjustment to opening equity on adoption. Early adoption is permitted. The Partnership is currently evaluating the impact of these events or how long any disruptions are likely to continue.
The following additional factors were considered in our first quarter 2020 analysis specific to the adoptionPartnership's Tuscarora and North Baja reporting units:
the long-term natural gas price futures relevant to gas transported on Tuscarora and North Baja do not reflect material differences from what was forecast in 2019;
at least 90 percent of this guidanceTuscarora's and hasNorth Baja's revenue is tied to long-term take-or-pay, fixed-price contracts which have a low correlation to short-term changes in demand;
Tuscarora and North Baja have not yet determinedexperienced any material customer defaults to date and have significant collateral in support of their contracts;
multiples and discount rate assumptions used in our quantitative model are reflective of the effectlong-term outlook for Tuscarora and North Baja, in line with their underlying asset lives, versus the shorter-term nature of the current situation;

Tuscarora's expansion project, Tuscarora XPress, is materially on its consolidated financial statements.

track, and we do not anticipate any significant changes in outlook or delay or inability to proceed due to financing requirements; and
Tuscarora and North Baja's businesses are broadly considered essential in the United States given the important role their infrastructures play in delivering energy to the market areas they serve.

As a result of these factors, we concluded during our first quarter 2020 analysis that there was a greater than 50 percent likelihood that both Tuscarora’s and North Baja’s estimated fair values would continue to exceed their carrying values. Therefore, no impairment exists on our goodwill. While the issues described above persist in the current quarter, we continue to believe these conditions remain temporary and are not aware of any other conditions or triggering events in the third quarter that would require us to change the conclusion reached during the first quarter. Adverse changes to our key considerations could, however, result in future impairments on our goodwill.

NOTE 6REVENUES
Disaggregation of Revenues
For the three and nine months ended September 30, 2020 and 2019, effectively all of the Partnership’s revenues were from capacity arrangements and transportation contracts with customers as discussed in more detail below.
Capacity Arrangements and Transportation Contracts
The Partnership’s performance obligations in its contracts with customers consist primarily of capacity arrangements and natural gas transportation contracts.
The Partnership’s revenues are generated from contractual arrangements for committed capacity and from transportation of natural gas which are treated as a bundled performance obligation. Revenues earned from firm contracted capacity arrangements are recognized ratably over the term of the contract regardless of the amount of natural gas that is transported. Transportation revenues for interruptible or volumetric-based services are recognized when the service is performed. The Partnership has elected to utilize the practical expedient of recognizing revenue as invoiced.
The Partnership's pipeline systems are subject to FERC regulations and, as a result, a portion of revenues collected may be subject to refund if invoiced during an interim period when a rate proceeding is ongoing. Allowances for these potential refunds are recognized using management's best estimate based on the facts and circumstances of the proceeding. Any allowances that are recognized during the proceeding process are refunded or retained, as applicable, at the time a regulatory decision becomes final. As of September 30, 2020, the Partnership does not have any outstanding refund obligations related to any rate proceedings. Revenues are invoiced and paid on a monthly basis. The Partnership’s pipeline systems do not take ownership of the natural gas that is transported for customers. Revenues from contracts with customers are recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities.
17





Contract Balances
All of the Partnership’s contract balances pertain to receivables from contracts with customers amounting to $32 million at September 30, 2020 (December 31, 2019 - $37 million) and are recorded as trade accounts receivable and reported as "Accounts receivable and other" in the Partnership’s consolidated balance sheet (Refer to Note 14, "Accounts Receivable and Other").
Additionally, our accounts receivable represent the Partnership’s unconditional right to consideration for services completed which includes billed and unbilled accounts.
Right to invoice practical expedient
In the application of the right to invoice practical expedient, the Partnership’s revenues from regulated capacity arrangements are recognized based on rates specified in the contract. Therefore, the amount invoiced, which includes the capacity contracted and variable volume of natural gas transported, corresponds directly to the value the customer received. These revenues are recognized on a monthly basis once the Partnership’s performance obligation to provide capacity has been satisfied.

On June 1, 2017, the Partnership acquired from subsidiaries of TransCanada a 49.34 percent interest in Iroquois, including an option to acquire a further 0.66 percent interest in Iroquois, together with an additional 11.81 percent interest in PNGTS resulting in the Partnership owning a 61.71 percent interest in PNGTS (2017 Acquisition). The total purchase price of the 2017 Acquisition was $765 million plus final purchase price adjustments amounting to $50 million. The purchase price consisted of (i) $710 million for the Iroquois interest (less $164 million, which reflected our 49.34 percent share of Iroquois outstanding debt on June 1, 2017), (ii) $55 million for the additional 11.81 percent interest in PNGTS (less $5 million, which reflected our 11.81% proportionate share in PNGTS’ outstanding debt on June 1, 2017) (iii) final working capital adjustments on PNGTS and Iroquois amounting to $3 million and $19 million, respectively and (iv) additional consideration for Iroquois’ surplus cash amounting to $28 million. Additionally, the Partnership paid $1,000 for the option to acquire TransCanada’s remaining 0.66 percent interest in Iroquois. The Partnership funded the cash portion of the 2017 Acquisition through a combination of proceeds from the May 2017 public debt offering (refer to Note 5) and borrowing under our Senior Credit Facility.

At the date of the 2017 Acquisition, there was significant cash on Iroquois’ balance sheet.  Pursuant to the Purchase and Sale Agreement associated with the acquisition of the Iroquois interest, as amended, the Partnership agreed to pay $28 million plus interest to TransCanada on August 1, 2017 for its 49.34 percent share of cash determined to be surplus to Iroquois’ operating needs.

Additionally, Iroquois’ partners adopted a distribution resolution to address the significant cash on Iroquois’ balance sheet post-closing. The Partnership expects to receive the $28 million of unrestricted cash as part of its quarterly

distributions from Iroquois over 11 quarters under the terms of the resolution, which began with Iroquois’ second quarter 2017 distribution on August 1, 2017. As of November 6, 2017 the Partnership has received approximately $5.2 million of the expected $28 million, of which $2.6 million was received on November 1, 2017 (Refer to Note 19).

The acquisition of a 49.34 percent interest in Iroquois was accounted for as a transaction between entities under common control, whereby the equity investment in Iroquois was recorded at TransCanada’s carrying value and the total excess purchase price paid was recorded as a reduction in Partners’ Equity.

Iroquois’ net purchase price was allocated as follows:

(b)             The excess purchase price of $370 million was recorded as a reduction in Partners’ Equity.

The acquisition of an additional 11.81 percent interest in PNGTS, which resulted in the Partnership owning 61.71 percent in PNGTS, was accounted for as a transaction between entities under common control, similar to a pooling of interests, whereby assets and liabilities of PNGTS were recorded at TransCanada’s carrying value and the Partnership’s historical financial information, except net income per common unit, was recast to consolidate PNGTS for all periods presented.

NOTE 7 8PARTNERS’ EQUITY

ATM equity issuance program (ATM program)

During the nine months ended September 30, 2017, we issued 2,165,162 common units under our ATM program generating net proceeds of approximately $124 million, plus $2 million contributed by the General Partner to maintain its effective two percent general partner interest. The commissions to our sales agents in the nine months ended September 30, 2017 were approximately $1 million. The net proceeds were used for general partnership purposes.

Class B units issued to TransCanada

TC Energy

The Class B Units we issued on April 1, 2015 to finance a portion of the 2015 GTN Acquisition represent a limited partner interest in us andunits entitle TransCanadaTC Energy to an annual distribution based on 30 percent of GTN’s annual

distributions as follows: (i) 100 percent of distributions above $20 million through March 31, 2020;2020 and (ii) 25 percent of distributions above $20 million thereafter.

thereafter, which equates to 43.75 percent of distributions above $20 million for the year ending December 31, 2020 (Class B Distribution). Additionally, the Class B Distribution will be further reduced by 35 percent, which is equivalent to the percentage by which distributions payable to the common units were reduced in 2018 (Class B Reduction). The Class B Reduction was implemented during the first quarter of 2018 following the Partnership’s common unit distribution reduction of 35 percent. The Class B Reduction will continue to apply to any particular calendar year until distributions payable in respect of common units for such calendar year equal or exceed $3.94 per common unit.

For the year ending December 31, 2017,2020, the Class B units’ equity account will be increased by the excess of 30 percent of GTN’s distributions overClass B Distribution, less the annual threshold of $20 millionClass B Reduction, until such amount is declared for distribution and paid in the first quarter of 2018.2021. During the nine months ended September 30, 2017, 30 percent of GTN’s total distributable cash flow was $28 million. As a result of exceeding2020, the $20 million threshold, the2020 annual Class B units’ equity accountDistribution threshold was increased by $8 million (Refer to Note 8).

not exceeded.

For the year ended December 31, 2016,2019, the Class B distributionDistribution was $22$8 million and was declared and paid in the first quarter of 2017.

Common unit issuance subject to rescission

In connection with a late filing of an employee-related Form 8-K with the SEC in March 2016, the Partnership became ineligible to use the then effective shelf registration statement upon filing of its Annual Report on Form 10-K for the year ended December 31, 2015. As a result, it was determined that the purchasers of the 1.6 million common units that were issued from March 8, 2016 to May 19, 2016 under the Partnership’s 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 such units to the Partnership. The Securities Act of 1933, as amended (Securities Act) generally requires that any claim brought for a violation of Section 5 of the Securities Act be brought within one year of violation.

At December 31, 2016, $83 million was recorded as common units subject to rescission on the consolidated balance sheet.  The Partnership classified the 1.6 million common units that were sold under its ATM program from March 8, 2016 up to and including May 19, 2016, which may have been subject to rescission rights, outside of equity given the potential redemption feature which was not within the control of the Partnership. These units were treated as outstanding for financial reporting purposes.

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.

NOTE 8 9NET INCOME PER COMMON UNIT

Net income per common unit is computed by dividing net income attributable to controlling interests, after deduction of net income attributable to PNGTS’ former parent, amounts attributable to the General PartnerTC PipeLines GP, Inc. (General Partner) and Class B units, by the weighted average number of common units outstanding.

The amountsamount allocable to the General Partner equals an amount based upon the General Partner’s effective two2 percent general partner interest, plus an amount equal to incentive distributions. Incentive distributions are paid to the General Partner if quarterly cash distributions on the common units exceed levels specified in the Partnership Agreement.

The amount allocable to the Class B units in 2017 equals2020 will equal 30 percent of GTN’s distributable cash flow during the year endedending December 31, 20172020 less $20 million, the residual of which is further multiplied by 43.75 percent. This amount is further reduced by the estimated Class B Reduction for 2020, an approximately 35 percent reduction applied to the estimated annual Class B Distribution (December 31, 2016 —$20 million).

Great Lakes
Great Lakes earns significant transportation revenues from TransCanadaTC Energy and its affiliates, some of which are provided at discounted rates and some at maximum recourse rates. For both the three and nine months ended September 30, 2017,2020, Great Lakes earned 4474 percent and 53 percent of its transportation revenues from TransCanadaTC Energy and its affiliates respectively (September 30, 2016 — 622019 - 73 percent and 69 percent)for both periods).

At September 30, 2017, $82020, $12 million was included in Great Lakes’ receivables in regardswith regard to the transportation contracts with TransCanadaTC Energy and its affiliates (December 31, 2016 —2019 - $19 million).

In 2018, Great Lakes operates underexecuted long-term transportation capacity contracts with its affiliate, ANR Pipeline Company (ANR) in anticipation of specific possible future needs. The original total contract value of these contracts was approximately $1.3 billion over a FERC approved 201315-year period. These contracts were subject to certain conditions and provisions, including a reduction option up to the full contract quantity if exercised up to a certain date. During the first quarter of 2020, several amendments were made to these contracts and ANR exercised the right to terminate a significant portion of the contracts amounting to approximately $1.1 billion. The remaining maximum rate settlement that includescontract, which has a revenue sharing mechanism that requirestotal capacity of approximately 168,000 Dth/Day and total contract value of $182 million over a term of 20 years, is expected to begin in late 2022. This contract, which has a full quantity reduction option at any time before October 1, 2022, is dependent on ANR being able to secure the required regulatory approvals and other requirements of the project associated with these volumes. Any remaining unsubscribed capacity on Great Lakes to share with its shippers certain percentages of any qualifying revenues earned above a certain return on equity threshold. For the year ended December 31, 2016, Great Lakes recorded an estimated 2016 revenue sharing provision of $7.2 million. For the three and nine months ended September 30, 2017, Great Lakes recorded an estimated 2017 revenue sharing provision of $12 million and $22 million, respectively. Great Lakes expects that a significant percentage of this refund will be paidavailable for contracting in response to its affiliates.

PNGTS earns transportation revenues from TransCanada and its affiliates. For three and nine months ended September 30, 2017, PNGTS earned approximately nil million and $1 million of its transportation revenues from TransCanada and its affiliates, respectively (2016 — $1 million and $2 million, respectively).

At September 30, 2017, nil million was included in PNGTS’ receivables in regards to the transportation contracts with TransCanada and its affiliates (December 31, 2016 — nil).

In connection with anticipated future commercial opportunities,the Portland XPress expansion project (PXP), which was designed to be phased in over a three-year time period, PNGTS has entered into an arrangement with its affiliates regarding the construction of certain facilities on their systems that will beare required to fulfill future contracts on the PNGTS’PNGTS system. In the event the anticipated developments do not proceed,expansions are terminated prior to their in-service dates, PNGTS willwould be required to reimburse its affiliates for any costs incurred related to the development of thesetheir facilities. At September 30, 2017, PNGTS does not haveOn November 1, 2020, the last phase of PXP (Phase III) was commercially placed in service. As a result of placing the TC Energy facilities associated with the Phases I, II and III volumes in service, PNGTS' reimbursement obligation to TC Energy relating to this project has been extinguished.
Commercial System Purchase
On August 1, 2020, GTN, Great Lakes, Tuscarora and North Baja entered into a purchase agreement with a TC Energy affiliate to purchase an obligationinternally developed customer-facing commercial natural gas transmission IT application that maintains and manages customer contracts, natural gas capacity release, customer nominations, metering and billings. The total value of the transaction was $51 million and the Partnership's proportionate share of the cost was $38 million. Prior to the transaction close, GTN, Great Lakes, Tuscarora and North Baja paid the affiliate for reimbursement underthe use of this arrangement.

NOTE 1213    FAIR VALUE MEASUREMENTS

(a) Fair Value Hierarchy

Under Accounting Standards Codification (ASC) 820, Fair Value Measurements and Disclosures, fair value measurements are characterized in one of three levels based upon the inputs used to arrive at the measurement. The three levels of the fair value hierarchy are as follows:

·

Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access at the measurement date.

·

Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

·

Level 3 inputs are unobservable inputs for the asset or liability.

When appropriate, valuations are adjusted for various factors including credit considerations. Such adjustments are generally based on available market evidence. In the absence of such evidence, management’s best estimate is used.

(b) Fair Value of Financial Instruments

The carrying value of cash"cash and cash equivalents, accounts" "accounts receivable and other, accounts" "accounts payable and accrued liabilities, accounts" "accounts payable to affiliatesaffiliates" and accrued interest"accrued interest" approximate their fair values because of the short maturity or duration of these instruments, or because the instruments bear a variable rate of interest or a rate that approximates current rates. The fair value of the Partnership’s debt is estimated by discounting the future cash flows of each instrument at estimated

current borrowing rates. The fair value of interest rate derivatives is calculated using the income approach, which uses period-end market rates and applies a discounted cash flow valuation model.

The Partnership has classified the fair value of natural gas imbalances as a Level 2 of the fair value hierarchy for fair value disclosure purposes, as the valuation approach includes quoted prices in the market index and observable volumes for the imbalance.
Long-term debt is recorded at amortized cost and classified inas Level 2 of the fair value hierarchy for fair value disclosure purposes. Interest rate derivative assets and liabilities are classified inas Level 2 for all periods presented where the fair value is determined by using valuation techniques that refer to observable market data or estimated market prices. The estimated fair value of the Partnership’s debt as at September 30, 20172020 and December 31, 20162019 was $2,555$2,257 million and $1,962$2,111 million, respectively.

Market risk is the risk that changes in market interest rates may result in fluctuations in the fair values or cash flows of financial instruments. The Partnership’s floating rate debt is subject to LIBOR benchmark interest rate risk. The Partnership uses interest rate derivatives to manage its exposure to interest rate risk. We regularly assess the impact of interest rate fluctuations on future cash flows and evaluate hedging opportunities to mitigate our interest rate risk.

The Partnership’s interest rate swaps aremature on October 2, 2022. The interest rate swaps were structured such that the cash flows of the derivative instruments match those of the variable rate of interest on the 2013 Term Loan Facility. The Partnership hedged interest payments on the variable-rate 2013 Term Loan Facility withfixed weighted average interest rate swaps maturing July 1, 2018, at a weighted average fixed interest rate of 2.31on these instruments is 3.26 percent.
At September 30, 2017,2020, the fair value of the interest rate swaps accounted for as cash flow hedges was an asseta liability of $2$17 million (both on a gross and net basis). At December (December 31, 2016, the fair value of the interest rate swaps accounted for as cash flow hedges was an asset of $1 million and a2019 - liability of $1 million (on a gross basis) and an asset$6 million), the net change of nil million (on a net basis). The Partnership did not record any amountswhich is recognized in net income related to ineffectiveness for interest rate hedges forother comprehensive income. For both the three and nine months ended September 30, 2017 and 2016. The change in fair value of interest rate derivative instruments recognized in other comprehensive income was nil and a gain of $1 million for the three and nine months ended September 30, 2017, respectively (September 30, 2016 — gain of $2 million and a loss of $1 million). For the three and nine months ended September 30, 2017,2020, the net realized loss related to the interest rate swaps was nil,$2 million and $4 million and was included in financial"financial charges and otherother" (September 30, 2016 —$12019 - gain of NaN and gain of $1 million, and $2 million)respectively) (Refer to Note 14) .

As discussed in Note 5, the Partnership’s $500 million 2013 Term Loan that was due July 1, 2018, was amended to extend the maturity period through October 2, 2022. At September 30, 2017, the entire $500 million 2013 Term Loan was hedged until July 1, 2018. As a result of this extension, the Partnership implemented an interest rate hedging strategy during the fourth quarter15, "Financial Charges and hedged the entire $500 million until its October 2, 2022 maturity using forward starting swaps at an average rate of 3.26 percent.

Other').

The Partnership has no master netting agreements; however, it has derivative contracts containing provisions with rights of offset. The Partnership has elected to present the fair value of derivative instruments with the right to offset on a gross basis in the consolidated balance sheet. Had the Partnership elected to present these instruments on a net basis, there would be no effect on the consolidated balance sheet as of September 30, 2017 (net asset of nil million as of2020 and December 31, 2016).

In anticipation of a debt refinancing in 2003, PNGTS entered into forward interest rate swap agreements to hedge the interest rate on its Senior Secured Notes due in 2018. These interest rate swaps were used to manage the impact of interest rate fluctuations and qualified as derivative financial instruments in accordance with ASC 815, Derivatives and Hedging. PNGTS settled its position with a payment of $20.9 million to counterparties at the time of the refinancing and recorded the realized loss in accumulated other comprehensive income as of the termination date. The previously recorded loss is currently being amortized against earnings over the life of the PNGTS Senior Secured Notes.  At September 30, 2017, our 61.71 percent proportionate share of net unamortized loss on PNGTS included in other comprehensive income was $1 million (December 31, 2016 - $2 million). For the three and nine months ended September 30, 2017, our 61.71 percent proportionate share of the amortization of realized loss on derivative instruments was nil and $1 million, respectively (September 30, 2016 —nil and $1 million).

NOTE 15CONTINGENCIES

Great Lakes v. Essar Steel Minnesota LLC, et al. —  On October 29, 2009, Great Lakes filed suit in the U.S. District Court, District of Minnesota, against Essar Minnesota LLC (Essar Minnesota) and certain Foreign Essar Affiliates (collectively, Essar) for breach of its monthly payment obligation under its transportation services agreement with Great Lakes. Great Lakes sought to recover approximately $33 million for past and future payments due under the agreement. On September 16, 2015, following a jury trial, the federal district court judge entered a judgment in the amount of $32.9 million in favor of Great Lakes.  On September 20, 2015, Essar appealed the decision to the United States Court of Appeals for the Eighth Circuit (Eighth Circuit) based on an allegation of improper jurisdiction and a number of other rulings by the federal district judge. Essar was required to post a performance bond for the full value of the judgment pending appeal.  The Eighth Circuit heard the appeal on October 20, 2016.  A decision on the appeal was received in December 2016 and the Eighth Circuit vacated Great Lakes’ judgment against Essar finding that there was no federal jurisdiction. Great Lakes filed a Request for Rehearing with the Eighth Circuit and it was denied in January 2017. Before the Circuit Court issued its decision, Essar Minnesota filed for bankruptcy in July 2016. The Foreign Essar Affiliates have not filed for bankruptcy. Following the Circuit Court’s decision, the performance bond was released into the bankruptcy court proceedings. Great Lakes filed a claim against Essar Minnesota in the bankruptcy court and its case against the Foreign Essar Affiliates in Minnesota state court remains pending. In April 2017, after Great Lakes agreement with creditors on an allowed claim, the bankruptcy court approved Great Lakes’ claim in the amount of $31.5 million.  On May 20, 2017, the federal district court awarded Essar Minnesota approximately $1.2 million for costs, including recovery of the performance bond premium, to be paid by Great Lakes. Great Lakes filed a motion with the bankruptcy court to offset the $1.2 million award of costs against its claim against Essar Minnesota in the bankruptcy proceeding.  If Great Lakes’ motion to offset the federal district court’s award of costs is against its claim in the bankruptcy proceeding is not successful, Great Lakes will be responsible to the bankruptcy estate for payment of the award. Great Lakes is unable to estimate the timing or the extent to which its claim will be recoverable in the bankruptcy proceedings.

NOTE 16REGULATORY

North Baja —On January 6, 2017, North Baja notified FERC that current market conditions do not support the replacement of the compression that was temporarily abandoned in 2013 and requested authorization to permanently abandon two compressor units and a nominal volume of unsubscribed firm capacity. FERC approved the permanent abandonment request on February 16, 2017. The abandonments will not have any impact on existing firm transportation service.

Great Lakes - 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- 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 Midwestern U.S.

NOTE 17 VARIABLE INTEREST ENTITIES

In the normal course of business, the Partnership must re-evaluate its legal entities under the current consolidation guidance to determine if those that are considered to be VIEs are appropriately consolidated or if they should be accounted for under other GAAP. A variable interest entity (VIE) is a legal entity that does not have sufficient equity at risk to finance its activities without additional subordinated financial support or is structured such that equity investors lack the ability to make significant decisions relating to the entity’s operations through voting rights or do not substantively participate in the gains or losses of the entity. A VIE is appropriately consolidated if the Partnership is considered to be the primary beneficiary. The VIE’s primary beneficiary is the entity that has both (1) the power to direct the activities of the VIE that most significantly impact the VIEs economic performance and (2) the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE.

As a result of its analysis, the Partnership continues to consolidate all legal entities in which it has a variable interest and for which it is considered to be the primary beneficiary. VIEs where the Partnership is not the primary beneficiary, but has a variable interest in the entity, are accounted for as equity investments.

Consolidated VIEs

The Partnership’s consolidated VIEs consist of the Partnership’s ILPs that hold interests in the Partnership’s pipeline systems. After considering the purpose and design of the ILPs and the risks that they were designed to create and pass through to the Partnership, the Partnership has concluded that it is the primary beneficiary of these ILPs because of the significant amount of variability that it absorbs from the ILPs’ economic performance.

The assets and liabilities held through these VIEs that are not available to creditors of the Partnership and whose investors have no recourse to the credit of the Partnership are held through GTN, Tuscarora, Northern Border, Great

Lakes, PNGTS and Iroquois due to their third party debt. The following table presents the total assets and liabilities of these entities that are included in the Partnership’s consolidated balance sheets:

NOTE 18 INCOME TAXES

The Partnership’s income taxes relate to business profits tax (BPT) levied at the partnership (PNGTS) level by the state of New Hampshire. As a result of the BPT, PNGTS recognizes deferred taxes related to temporary differences between the financial statement carrying amount of existing assets and liabilities and their respective tax bases. The deferred taxes at September 30, 2017 and December 31, 2016 relate primarily to utility plant. At September 30, 2017 and December 31, 2016 the New Hampshire BPT effective tax rate was 3.8 percent for both periods and was applied to PNGTS’ taxable income.

NOTE 1916    SUBSEQUENT EVENTS

Management of the Partnership has reviewed subsequent events through November 6, 2017,9, 2020, the date the consolidated financial statements were issued, and concluded there were no events or transactions during this period that would require recognition or disclosure in the consolidated financial statements other than what is disclosed here and/or those already disclosed in the preceding notes.

Distributions
On October 24, 2017,21, 2020, the board of directors of the General Partner (TC PipeLines Board) declared the Partnership’s third quarter 20172020 cash distribution in the amount of $1.00$0.65 per common unit payable on November 14, 201713, 2020 to unitholders of record as of November 3, 2017.2, 2020. The declared distribution totaled $75$47 million and is payable in the following manner: $70$46 million to common unitholders (including $6$4 million to the General Partner as a holder of 5,797,106 common units and $11$7 million to another subsidiary of TransCanadaTC Energy as holder of 11,287,725 common units) and $5$1 million to the General Partner which included $2 million for its effective two2 percent general partner interest and $3 millioninterest. The General Partner did not receive any distributions in respect of its IDRs.

IDRs for the third quarter of 2020.

Northern Border declared its September 20172020 distribution of $14$18 million on October 9 2017,2020, of which the Partnership received its 50 percent share or $9 million on October 30, 2020.
Iroquois declared its third quarter 2020 distribution of $21 million on November 2, 2020, of which the Partnership will receive its 5049.34 percent share or $7$10 million on October 31, 2017.

Great Lakes' Contract with TC Energy's Canadian Mainline
As noted in our 2019 Annual Report, a significant portion of Great Lakes’ total contract portfolio is contracted by its affiliates including its long-term transportation agreement with TC Energy’s Canadian Mainline that commenced on November 1, 2017.

Iroquois declared2017 for a ten-year period that allows TC Energy to transport up to 0.711 billion cubic feet (equivalent to about 722,000 Dth/day) of natural gas per day on the Great Lakes system. This contract contained a volume reduction option up to full contract quantity until November 1, 2020. During the quarter, the Canadian Mainline requested an extension on the volume reduction option deadline and Great Lakes extended the option expiry to November 16, 2020.


TC Energy's offer to acquire the Partnership's publicly-held outstanding common units:
27





On October 5, 2020, the Partnership announced receipt of a non-binding offer from TC Energy to acquire all of its third quarter 2017 distributionoutstanding common units not beneficially owned by TC Energy or its affiliates in exchange for common shares of $28 millionTC Energy. Under the proposal, the Partnership's common unitholders would receive 0.65 common shares of TC Energy for each issued and outstanding publicly-held Partnership common unit (TCP common unit), representing an implied value of $27.31 per TCP common unit based on the closing price of TC Energy common shares on the New York Stock Exchange (NYSE) on October 23, 2017,2, 2020 (TC Energy Proposal). This reflects a 7.5 percent premium to the exchange ratio implied by the 20-day volume weighted average prices of whichthe Partnership's common units and TC Energy’s common shares on the NYSE as of October 2, 2020.

The offer has been made to the TC PipeLines Board. As the general partner of the Partnership received its 49.34 percent share or $14 million on November 1, 2017. The distribution includes our 49.34 percent shareis an indirect wholly-owned subsidiary of TC Energy, a conflicts committee composed of independent directors of the Iroquois unrestricted cash distribution amountingTC PipeLines Board (the Conflicts Committee) was formed to approximately $2.6 million (Referconsider the offer pursuant to Note 6)the Fourth Amended and Restated Agreement of Limited Partnership of the Partnership (Partnership Agreement).


The transaction is subject to the review and favorable recommendation by the Conflicts Committee of the TC PipeLines Board and approvals by the TC PipeLines Board, the Board of Directors of TC Energy, and the holders of a majority of the outstanding common units of the Partnership. It is also subject to the negotiation and execution of an agreement and plan of merger, which would provide the definitive terms of the transaction, including the exchange ratio, and customary regulatory approvals. Any definitive agreement is expected to contain customary closing conditions. There can be no assurance that any such approvals will be forthcoming, that a definitive agreement will be executed or that any transaction will be consummated.

Item 2.   Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with the unaudited consolidated financial statements and notes included in Item 1. “Financial Statements” of this Quarterly Report on Form 10-Q, as well as our 2019 Annual ReportReport.

RECENT BUSINESS DEVELOPMENTS
COVID-19

On March 11, 2020, the WHO declared COVID-19, a global pandemic. As primary operator of our pipelines, TC Energy’s business continuity plans remain in place across the organization and TC Energy continues to effectively operate our assets, conduct commercial activities and execute on Form 10-Kprojects with a focus on health, safety and reliability. Our business is broadly considered essential in the United States given the important role our infrastructure plays in providing energy to North American markets. We believe that TC Energy’s robust continuity and business resumption plans for critical teams including gas control and commercial and field operations, will continue to ensure the year ended December 31, 2016,safe and reliable delivery of energy that our customers depend upon.

Our pipeline assets are largely backed by long-term, take-or-pay contracts resulting in revenues that are materially insulated from short-term volatility associated with fluctuations in volume throughput and commodity prices. More importantly, a significant portion of our long-term contract revenue is with investment-grade customers and we have not experienced any material collection issues on our receivables to date. Aside from the impact of maintenance activities and normal seasonal factors, to date we have not seen any material changes in the utilization of our assets. Additionally, to date, we have not experienced any significant impacts on our supply chain. While it is too early to ascertain any long-term impact that the COVID-19 pandemic may have on our capital growth program, we note that we could experience some delay in construction and other related activities.

Capital market conditions in 2020 have been significantly impacted by COVID-19 resulting in periods of extreme volatility and reduced liquidity. Despite these challenges, our liquidity remains strong, underpinned by stable cashflow from operations, cash on hand and full access to our $500 million Senior Credit Facility. During the second quarter of 2020, GTN's $100 million Senior Notes due in June 2020 were refinanced through a Note Purchase Agreement whereby GTN issued $175 million of 10-year Series A Senior Notes with a coupon rate of 3.12% with the incremental $75 million of proceeds to be used to fund the GTN XPress project through the balance of 2020. Additionally, GTN entered into a 3-year private shelf agreement for an additional $75 million which certain partswill be used to finance a portion of the reportGTN XPress project into 2023. During the fourth quarter of 2020, PNGTS entered into a Note Purchase Agreement whereby PNGTS issued $125 million 10-year Series A Senior Notes with a coupon rate of 2.84%, the proceeds of which were amendedprimarily used to repay the outstanding balance of PNGTS' Revolving Credit Facility. The remaining proceeds were used for general partnership purposes, including the funding of PXP and Westbrook XPress. PNGTS also entered into a 3-year private shelf agreement for an additional $125 million which will be used to finance the remaining capital spending required for Westbrook XPress into 2021. Additionally, on July 23, 2020, Tuscarora's $23 million Unsecured Term Loan due in August 2020 was extended for one year to August 2021 under generally the same terms. These recently concluded transactions demonstrate our continued access to the debt capital markets at attractive levels. We continue to conservatively manage our financial position, self-fund our ongoing capital expenditures and maintain our debt at prudent levels and we believe we are well positioned to fund our obligations through a prolonged period of disruption, should it occur. Based on current expectations, we believe our business will continue to deliver consistent financial performance going forward and support our current quarterly distribution level of $0.65 per common unit.

The full extent and lasting impact of the Partnership’s filingCOVID-19 pandemic on the global economy is uncertain but to date has included extreme volatility in financial markets and commodity prices, a significant reduction in overall economic activity and widespread extended shutdowns of Current Reportbusinesses along with supply chain disruptions. The degree to which COVID-19 has a more significant impact on Form 8-K dated August 3, 2017 to give retrospective adjustments to include the results ofour operations and financial positiongrowth projects will depend on future developments, policies and actions which remain highly uncertain. Additional information regarding risks and impacts on our business can be found throughout this section, including Item 3 - "Quantitative and Qualitative Disclosures About Market Risk" and Part II-Item 1A - "Risk Factors."

Impairment considerations:
29





Under U.S. GAAP, we evaluate our goodwill related to Tuscarora and North Baja for impairment at least annually to determine if any indicators of impairment are evident. Our long-lived assets and equity investments in Northern Border, Great Lakes and Iroquois, including intangible assets with finite useful lives, are evaluated whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable.
We believe the current state of the macroeconomic environment described above does not represent a permanent shift although it is difficult to predict the severity of the impact of these events or how long any disruptions are likely to continue. Additionally, the following factors were considered in our analysis specific to the Partnership:

the long-term natural gas price futures relevant to gas transported on our pipelines do not reflect material differences from what was forecast in 2019;
a significant amount of our pipeline assets’ revenue is tied to long-term take-or-pay, fixed-price contracts which have a low correlation to short-term changes in demand;
we have not experienced any material customer defaults to date and we have significant collateral supporting our contracts;
multiples and discount rate assumptions used in our quantitative models are reflective of the long-term outlook for our assets, in line with their underlying asset life, versus the shorter-term nature of the current situation;
while we may experience a slowdown in some of our construction activities, our current growth projects are materially on track, and we do not anticipate any significant changes in outlook, delays or inability to proceed due to financing requirements; and
our businesses are broadly considered essential in the United States given the important role these pipeline infrastructure assets play in delivering energy to the market areas we serve.

While the issues described above persist in the current quarter, we continue to believe these conditions remain temporary and as a result, we continue to believe no impairment exists on our goodwill, equity investments or long-lived assets. However, future adverse changes to our key considerations could change our conclusion.
TC Energy's offer to acquire the Partnership's outstanding publicly-held common units:
On October 5, 2020, the Partnership announced a non-binding offer from TC Energy to acquire all of its outstanding common units not beneficially owned by TC Energy or its affiliates in exchange for common shares of TC Energy. Under the proposal, the Partnership's common unitholders would receive 0.65 common shares of TC Energy for each issued and outstanding publicly-held Partnership common unit, representing an implied value of $27.31 per TCP common unit based on the closing price of TC Energy common shares on the NYSE on October 2, 2020. This reflects a 7.5 percent premium to the exchange ratio implied by the 20-day volume weighted average prices of the Partnership's common units and TC Energy’s common shares on the NYSE as of October 2, 2020.

The offer has been made to the TC PipeLines Board. As the general partner of the Partnership is an indirect wholly-owned subsidiary of TC Energy, a conflicts committee composed of independent directors of the TC PipeLines Board was formed to consider the offer pursuant to the Partnership Agreement.

The transaction is subject to the review and favorable recommendation by the Conflicts Committee of the TC PipeLines Board and approvals by the TC PipeLines Board, the board of directors of TC Energy, and the holders of a majority of the outstanding common units of the Partnership. It is also subject to the negotiation and execution of an agreement and plan of merger, which would provide the definitive terms of the transaction, including the exchange ratio, and customary regulatory approvals. Any definitive agreement is expected to contain customary closing conditions. There can be no assurance that any such approvals will be forthcoming, that a definitive agreement will be executed or that any transaction will be consummated.

Other notable business developments:

PNGTS’ Portland XPress Project - Our Portland XPress Project or “PXP” was initiated in 2017 in order to expand deliverability on the PNGTS system to Dracut, Massachusetts through re-contracting and construction of incremental compression within PNGTS’ existing footprint in Maine. PXP was designed to be phased in over a three-year time period. Phases I and II were placed into service on November 1, 2018 and 2019 respectively. On November 1, 2020, the last phase of PXP (Phase III) was commercially placed in service. All phases of the project are now fully in-service.

Beginning in 2021, PXP is expected to generate approximately $50 million in annual revenue for PNGTS. PXP is secured by long-term transportation agreements and PNGTS is now effectively fully contracted until 2032.

PNGTS’ Westbrook XPress Project - Phase I of this project is in service, and on June 18, 2020, FERC issued a certificate of public convenience and necessity for this project. Phases II and III have estimated in-service dates of November 2021 and 2022, respectively. Once fully in service, all periods presented (Referthree phases of Westbrook XPress in aggregate are expected to Notes 2generate approximately $35 million of annual revenue for PNGTS.

ANR's Alberta XPress project -On February 12, 2020, TC Energy approved the Alberta XPress project, an expansion project on its ANR Pipeline system with an estimated in-service date of 2022. This project utilizes existing capacity on the Great Lakes system (of which we own 46.45 percent) and 6TC Energy’s Canadian Mainline systems to connect growing natural gas supply from the Western Canadian Sedimentary Basin (WCSB) to U.S. Gulf Coast Liquified Natural Gas (LNG) export markets. In 2018, Great Lakes entered into long-term transportation capacity contracts with ANR for approximately 900,000 Dth/day of aggregate capacity for a term of 15 years. In connection with the approval of the Alberta XPress project, such contracts have been reduced to provide for approximately 168,000 Dth/day of aggregate capacity for a term of 20 years at maximum rates for a total contract value of $182 million starting in 2022. The contract contains reduction options (i) at any time on or before October 1, 2022 for any reason and (ii) at any time, if ANR is not able to secure the required regulatory approval related to its anticipated expansion projects. Please read Note 12 within Item 1. “Financial Statements” for information regarding Great Lakes and ANR.

Iroquois Gas Transmission ExC Project (Iroquois ExC Project) - In 2019, Iroquois initiated the “Enhancement by Compression” project (ExC Project) which will optimize the Iroquois system to meet current and future gas supply needs of utility customers while minimizing the environmental impact through enhancements at existing compressor stations along the pipeline. In February 2020, Iroquois filed an application with FERC to authorize the construction of the project. On September 30, 2020, FERC issued its Environmental Assessment (EA) for the Iroquois ExC Project. The EA concluded that approval of the project, with appropriate mitigating measures, would not constitute a major federal action significantly affecting the quality of the human environment. The project’s total design capacity is approximately 125,000 Dth/day with an estimated cost of $250 million and in-service date of November 2023. This project will be 100 percent underpinned with 20-year contracts.

Northern Border complaint - On March 31, 2020, BP Canada Energy Marketing Corp., Oasis Petroleum Marketing LLC and Tenaska Marketing Ventures (the “Alliance for Open Markets”) filed a complaint with FERC (Docket No. RP20-745-000) against Northern Border Pipeline Company alleging that Northern Border violated Sections 4 and 5 of the Natural Gas Act, FERC policy and other regulations by (i) failing to post capacity as available on a long-term basis before entering into a prearranged transaction for six agreements with ONEOK Rockies Midstream, L.L.C.; (ONEOK Midstream) and (ii) structuring the prearranged transaction open season in a manner that denied other shippers a meaningful opportunity to bid on the capacity. On April 2, 2020, ConocoPhillips Company, Shell Energy North America (US), L.P. and XTO Energy Inc. (the “Indicated Shippers”, together with the Alliance for Open Markets, the “Complainants”) filed a second complaint with FERC (Docket No. RP20-767-000) against Northern Border containing similar allegations regarding the prearranged transaction open season.  The Complainants have requested that FERC (a) unwind the six prearranged contracts; (b) require Northern Border to hold an open season for the capacity such that all interested parties are on equal footing; and (c) direct Northern Border to cease from engaging in prearranged transactions where the unsubscribed capacity has not been publicly posted as generally available. 
The prearranged contracts range in volume from 40,000 to 269,732 Dth/day for terms ranging from 10 months to 10 years, two of which began on June 1, 2020. Northern Border filed a motion to consolidate the two complaint dockets and filed its response to the complaints on May 1, 2020.

On June 1,2020 updated tariff sheets reflecting the contract price were filed by Northern Border with FERC for the two contracts set to begin June 1, 2020. On July 1, 2020, FERC issued an order and accepted the tariff sheets, subject to the outcome of complaint proceedings.

On October 15, 2020, FERC issued an order on the complaints and directed Northern Border to (1) refrain from making similar, discriminatory awards of capacity in the future, (2) rescind the pre-arranged deals with ONEOK Midstream, effective October 15, 2020, and (3) hold a new open season without a pre-arranged shipper. In addition, FERC directed Northern Border to file revisions to its tariff requiring it to post capacity on its website before entering a pre-arranged deal.

31





FERC did not order Northern Border to refund any of the revenue earned from the pre-arranged transactions with ONEOK Midstream.

Northern Border held an open season from October 21 to 28, 2020 to remarket the capacity. Final bids were evaluated and the successful bids will reflect a revenue that approximates Northern Border’s maximum recourse rates, which reflects a reduction from the pre-arranged contract rate.

Great Lakes 501-G Proceeding-On May 11, 2020, FERC terminated Great Lakes’ 501-G proceeding and ruled that Great Lakes has complied with the one-time reporting requirement, designated as FERC Form No. 501-G related to the rate effect of Tax Act and Jobs Act. Additionally, FERC also stated that rate reductions provided for in its 2017 settlement and the 2.0% rate reduction from the Limited Section 4 Rate Reduction proceeding have provided substantial rate relief for Great Lakes’ shippers and as a result, it will not exercise its right to institute a Natural Gas Act Section 5 investigation to determine if Great Lakes is over-recovering on its current tariff rates.

Great Lakes' credit rating upgrade - On June 21, 2020, Standard & Poor's (S&P) upgraded Great Lakes' credit rating by two-notches from BBB-/Stable to BBB+/Stable primarily due to an improvement in Great Lakes' financial risk profile resulting from its increased long-term contracting levels.

PNGTS credit rating upgrade - On July 24, 2020, Fitch upgraded PNGTS' credit rating by one-notch from BBB/Stable to BBB+/Stable primarily due to an improvement in PNGTS' financial risk profile resulting from placing is PXP Phase II project in-service on November 1, 2019.

Northern Border credit rating upgrade – On September 3, 2020, S&P affirmed Northern Border’s credit rating at BBB+ and upgraded the outlook from Stable to Positive based on strong recontracting, continued stable cashflows, conservative leverage, solid shipper base and strong sponsors.

Credit rating affirmation - On September 30, 2020, S&P affirmed the Partnership's BBB/Stable credit rating. S&P continues to consider the Partnership's business risk profile to be a key strength underpinned by its highly contracted, long-term, take-or-pay contracts with creditworthy counterparties. S&P further recognizes the Partnership's strong basin diversification and benefits associated with its strategic relationship with TC Energy despite the expected higher leverage due to the funding of its growth projects. On October 30, 2020 Moody's also affirmed the Partnership's credit rating at Baa2/Stable.

On October 6, 2020 S&P revised the Partnership's outlook from Stable to Creditwatch Positive in connection with TC Energy's offer to acquire the Partnership's outstanding common units. The Creditwatch reflects S&P's opinion that TC Energy's offer to acquire all of the outstanding units will increase the level of parental support from TC Energy. Tuscarora was also placed on Creditwatch Positive.

GTN financing - On June 1, 2020, GTN’s $100 million 5.29 percent Senior Notes matured and were refinanced through a Note Purchase and Private Shelf Agreement whereby GTN issued $175 million of 10-year Series A Senior Notes with a fixed rate coupon rate of 3.12 percent per annum and entered into a three-year private shelf agreement for an additional $75 million. The new Series A Senior Notes do not require any principal payments until maturity on June 1, 2030. Proceeds from the Series A Senior Note issuance were used to repay the outstanding balance of the 5.29 percent Senior Notes and to fund the GTN XPress capital expenditures through the balance of 2020. GTN expects to draw the remaining $75 million available under the GTN Private Shelf Facility by the end of 2023, the estimated completion date of GTN XPress. The GTN Private Shelf Agreement contains a covenant that limits total debt to no greater than 65 percent of GTN’s total capitalization.

Tuscarora financing - On July 23, 2020, Tuscarora's $23 million Unsecured Term Loan due August 21, 2020 was amended to extend the maturity date to August 20, 2021 under generally the same terms.

PNGTS financing - On October 8, 2020, PNGTS entered into a Note Purchase and Private Shelf Agreement whereby PNGTS issued $125 million of 10-year Series A Senior Notes with a coupon of 2.84% per annum and entered into a three-year private shelf agreement for an additional $125 million Senior Notes. The PNGTS Series A Notes do not require any principal payments until maturity on October 8, 2030. Proceeds from the Series A Senior Note issuance were used to repay the outstanding balance of PNGTS' Revolving Credit Facility and for general partnership purposes including funding of growth capital. PNGTS expects to draw the remaining $125 million available under the Private Shelf Facility by the end of 2021, the estimated completion date of its Westbrook XPress project. The PNGTS Private

Shelf Agreement contains a covenant that limits total debt to no greater than 65 percent of PNGTS’ total capitalization and requires PNGTS to maintain a leverage ratio of no greater than 5.00 to 1.00.

Commercial system purchase - On August 1, 2020, GTN, Great Lakes, Tuscarora and North Baja entered into a purchase agreement with a TC Energy affiliate to purchase an internally developed customer-facing commercial natural gas transmission IT application that maintains and manages customer contracts, natural gas capacity release, customer nominations, metering and billings. The total value of the transaction was $51 million and the Partnership's proportionate share of the cost was $38 million. Prior to the transaction close, GTN, Great Lakes, Tuscarora and North Baja paid the affiliate for the use of this Quarterlysystem. As a result of the capital purchase, the amount paid by each pipeline will be added to its respective rate base and utilized in the calculation of maximum allowable rates.

Pacific Gas and Electric Company - In early 2019, GTN’s largest customer, Pacific Gas and Electric Company (Pacific Gas), filed for Chapter 11 bankruptcy protection. Pacific Gas accounted for less than 10 percent Partnership’s consolidated revenues in 2019. On July 1, 2020, Pacific Gas emerged from its bankruptcy proceedings. To date, GTN has not experienced any collection issues on its receivable from Pacific Gas and we expect this to continue going forward.

Iroquois' Wright Interconnect Project - During the first quarter of 2020, Iroquois received a notice of termination of its precedent agreement with Constitution pipeline related to its Wright Interconnect Project. In April 2020, Iroquois exercised its contractual right for reimbursement through a guarantee from Williams Partners, L.P., a 41 percent owner of the Constitution pipeline project. During the third quarter of 2020, the parties reached an agreement for a $48.5 million reimbursement of project costs, recovering all but $3 million of capital expenditures spent by Iroquois on the project. The proceeds received by Iroquois were distributed to its partners, of which the Partnership's proportionate share was approximately $24 million. The proceeds received by the Partnership were treated as a return of capital and used for general partnership purposes.

Great Lakes' Contract with TC Energy's Canadian Mainline - As noted in our 2019 Annual Report, a significant portion of Great Lakes’ total contract portfolio is contracted by its affiliates including its long-term transportation agreement with TC Energy’s Canadian Mainline that commenced on Form 10-Q).

RECENT BUSINESS DEVELOPMENTS

November 1, 2017 for a ten-year period that allows TC Energy to transport up to 0.711 billion cubic feet (equivalent to about 722,000 Dth/day) of natural gas per day on the Great Lakes system. This contract contained a volume reduction option up to full contract quantity until November 1, 2020. During the quarter, the Canadian Mainline requested an extension on the volume reduction option deadline and Great Lakes extended the option expiry to November 16, 2020.

Pipeline updates

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. 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 Midwestern U.S.

Northern Border Contracting — Northern Border revenues are now substantially supported by firm transportation contracts through March 2020. The continued successful renewals of these contracts provide a strong indication of Northern Border’s attractiveness to its customers.

PNGTS Projects

Continent to Coast (C2C) Project

As previously reported in our 2016 Annual Report on the Form 10-K dated February 28, 2017, PNGTS filed to increase its FERC-certificated capacity as contemplated in its Continent-to-Coast (C2C) contracts, bringing its capacity capability up to 210,000 Dth/day effective November 1, 2017. PNGTS has not received full regulatory approvals to date but will cooperatively work with C2C shippers while awaiting approvals.

Portland XPress Project

PNGTS has executed Precedent Agreements with several Local Distribution Companies 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.

Acquisitions and Financing

Debt Offering — On May 25, 2017, the Partnership closed a $500 million public offering of senior unsecured notes bearing an interest rate of 3.90 percent maturing May 25, 2027. The net proceeds of $497 million were used to fund a portion of the 2017 Acquisition (Refer to Note 6 within Item 1. “Financial Statements” of this Quarterly Report on Form 10Q).

2017 Acquisition — On June 1, 2017, the Partnership completed the acquisitions of a 49.34 percent interest in Iroquois from subsidiaries of TransCanada including an option to acquire a further 0.66 percent interest in Iroquois, together with an additional 11.81 percent interest in PNGTS that resulted in the Partnership owning a 61.71 percent interest in PNGTS. The total purchase price of the 2017 Acquisition was $765 million plus the final purchase price adjustments amounting to approximately $50 million. The purchase price consisted of  (i) $710 million for the Iroquois interest (less $164 million, which reflected the Partnership’s 49.34 percent share of Iroquois outstanding debt at the time of the 2017 Acquisition   (ii) $55 million for the additional 11.81 percent in PNGTS (less $5 million, which reflected our 11.81 percent share in PNGTS’ outstanding debt at the time of the 2017 Acquisition) (iii) final working capital adjustments on PNGTS and Iroquois amounting to $3 million and $19 million, respectively and (iv) additional consideration on Iroquois’ surplus cash amounting to $28 million. The Partnership funded the cash portion of the 2017 Acquisition through a combination of proceeds from the May 25, 2017 public debt offering and borrowing under its Senior Credit Facility

As at the date of the 2017 Acquisition, there was significant cash on Iroquois’ balance sheet.  Pursuant to the Purchase and Sale Agreement associated with the acquisition of the Iroquois interest, as amended, the Partnership agreed to pay $28 million plus interest to TransCanada on August 1, 2017 for its 49.34 percent share of cash determined to be surplus to Iroquois’ operating needs.

Additionally, Iroquois’ partners adopted a distribution resolution to address the significant cash on Iroquois’ balance sheet post-closing. The Partnership expects to receive the $28 million of unrestricted cash as part of its quarterly distributions from Iroquois over 11 quarters under the terms of the resolution, which began with Iroquois’ second quarter 2017 distribution on August 1, 2017. As of November 6, 2017 the Partnership has received approximately $5.2 million of the expected $28 million, of which $2.6 million was received on November 1, 2017.

The Iroquois pipeline transports natural gas under long-term contracts and extends from the TransCanada Mainline system at the U.S. border near Waddington, New York to markets in the U.S. northeast, including New York City, Long Island and Connecticut.  Iroquois provides service to local gas distribution companies, electric utilities and electric power generators, as well as marketers and other end users, directly or indirectly, through interconnecting pipelines and exchanges throughout the northeastern U.S. Both the Iroquois and PNGTS pipelines are critical natural gas infrastructure systems in the Northeast U.S. market and the addition of Iroquois to the Partnership’s asset portfolio will further diversify our cash flow.

Tuscarora Refinancing — On August 21, 2017, Tuscarora refinanced all of its outstanding debt by amending its existing Unsecured Term Loan Facility and issuing a new $25 million variable rate term loan that will require yearly principal payments and will mature on August 21, 2020. Tuscarora’s Unsecured Term Loan contains a covenant that requires Tuscarora to maintain a debt service coverage ratio (cash available from operations divided by a sum of interest expense and principal payments) of greater than or equal to 3.00 to 1.00. As of September 30, 2017, the ratio was 3.08 to 1.00.

2013 Term Loan Facility - On September 29, 2017, the Partnership’s variable rate 2013 $500 million Term loan facility that was due on July 1, 2018 was amended to extend the maturity period through October 2, 2022. At September 30, 2017, the $500 million 2013 Term loan facility is hedged by fixed interest rate swap arrangements at an effective interest rate of 2.31 percent, expiring July 1, 2018. As a result of this extension, the Partnership implemented an interest rate hedging strategy during the fourth quarter and hedged the entire $500 million until its October 2, 2022 maturity using forward starting swaps at an average rate of 3.26 percent.

2015 Term Loan Facility-On September 29, 2017, the Partnership’s 2015 $170 million Term loan facility that was due on October 1, 2018 was amended to extend the maturity period through October 1, 2020.

HOW WE EVALUATE OUR OPERATIONS

We use certain non-GAAP financial measures that do not have any standardized meaning under GAAP as we believe they enhance the understanding of our operating performance.  We use the following non-GAAP measures:

EBITDA

We define EBITDA as our net income before deducting interest, depreciation and amortization and taxes. We use EBITDA as a proxy of our operating cash flow and current operating profitability.

Adjusted EBITDA
Adjusted EBITDA is our EBITDA, less (1) earnings from our equity investments, plus (2) distributions from our equity investments, and plus or minus (3) certain non-recurring items (if any) that are significant but not reflective of our underlying operations. We provide Adjusted EBITDA as an additional performance measure of the current operating profitability of our assets.
Distributable Cash Flows

Total distributable cash flow and distributable cash flow provide measures of distributable cash generated during the current earnings period.

Please see “Non-GAAP Financial Measures: EBITDA, Adjusted EBITDA and Distributable Cash Flow” for more information.


RESULTS OF OPERATIONS

Our equityownership interests in Northern Border, Great Lakes, and effective June 1, 2017, Iroquois and full ownerships of GTN, Bison, North Baja and Tuscarora and beginning also on June 1, 2017, 61.71 percent ownership in PNGTSeight pipelines were our only material sources of income during the period. Therefore, our results of operations and cash flows were influenced by, and reflect the same factors that influenced, our pipeline systems.

Net income attributable to controlling interests - 2019

The Partnership’s net income attributable to controlling interests was lower by $4 millionincreased in the three months ended September 30, 2020 compared to priorthe same period in 2019, mainly due to the net effect of lower revenues and overall higher costs partially offset by higher equity earnings.

following:

Equity Earnings - The $5$8 million increase was primarily due to the additionlargely a one time result of equityhigher earnings from Iroquois, resulting from the addition of Iroquois to our portfolio of assets effective June 1, 2017 partially offset by lower equity earnings frominvestment in Northern Border and Great Lakes dueprimarily related to highercertain pre-arranged contracts with ONEOK Midstream entered into by Northern Border that resulted in incremental revenue on the 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.

quarter. As noted under "Recent Business Developments" within Item 2, the pre-arranged contracts were cancelled by FERC effective October 15, 2020. The capacity was remarketed, and awarded under terms that approximate Northern Border’s maximum recourse rates, which are lower than the pre-arranged contract rates and is more consistent with historical results.


Operating, maintenance and administrative costs - The $1$2 million decrease was primarily due to:
lower operating costs related to our pipeline systems' compliance programs; and
decrease in TC Energy's allocated costs related to personnel.
Depreciation and amortization - The $10 million increase was mainly attributableis related to higher pipeline integrity onincreased maintenance capital expenditures at GTN and overall higher allocated management and operational expenses on our pipeline systems as performed by TransCanada.

Net income attributable to controlling interests - 2019

The Partnership’s net income attributable to controlling interests was lowerincreased by $2$6 million in the nine months ended September 30, 2020 compared to priorthe same period in 2019, mainly due to the net effect of lower revenues and overall higher costs partially offset by higher equity earnings.

following:

Transmission revenues Comparable- The $4 million decreasewas largely the net result of the following:
lower revenueon GTN due to prior year(i) its scheduled 6.6 percent rate decrease effective January 1, 2020, (ii) lower discretionary services sold primarily due to moderate weather conditions in early 2020 compared to colder weather experienced in early 2019, (iii) additional sales in 2019 related to regional supply constraints from a force majeure event experienced by a neighboring pipeline that were not repeated in 2020; and (iv) lower opportunity for the sale of discretionary services during the second quarter given the increased natural gas storage injection rates upstream of GTN;
lower revenueon Tuscarora due to its scheduled 10.8 percent rate decrease effective August 1, 2019;

Equity Earnings - The $12$8 million increase was primarily due the additionlargely a one time result of equityhigher earnings from Iroquois,our equity investment in Northern Border primarily related to certain pre-arranged contracts with ONEOK Midstream entered into by Northern Border that resulted in incremental revenue on the pipeline during the quarter. As noted under "Recent Business Developments" within Item 2, the pre-arranged contracts were cancelled by FERC effective June 1, 2017.

October 15, 2020. The capacity was remarketed, and awarded under terms that approximate Northern Border’s maximum recourse rates, which are lower than the pre-arranged contract rates and more consistent with historical results.

Operating, maintenance and administrative costs - The $7$4 million decrease was primarily due to:
lower operating costs related to our pipeline systems' compliance programs; and
a decrease in TC Energy's allocated costs related to personnel.
Depreciation and amortization - The $10 million increase was mainly attributableis related to higher pipeline integrity onincreased maintenance capital expenditures at GTN and overall higher allocated management and operational expenses on our pipeline systems as performed by TransCanada.

Net Income Attributable to Common Units and Net Income per Common Unit

2017

As discussed in Note 9 within Item 1. “Financial Statements,” we will allocate a portion of the Partnership’s income to the Class B units after the annual threshold is exceeded which will effectively reduce the income allocable to the common units and net income per common unit. Beginning in 2020 and beyond, we expect the impact of the Class B distribution on our cashflows to be significantly lower compared to previous periods due to TC Energy's reduced share of GTN's distributable cashflows beginning at the end of March 2020 as part of the Class B agreement. Please also read Note 8 within Item 1. “Financial Statements,” we allocated $8 million of the Partnership’s net income attributable to controlling interests tofor additional disclosures on the Class B units in the three and nine months ended September 30, 2017, respectively, representing the excess of 30 percent of GTN’s distribution over the 2017 threshold level of $20 million. This allocation reduced net income attributable to the common units and accordingly, reduced net income per common unit by approximately 12 cents for both the three and nine months ended September 30, 2017, respectively.

2016

We allocated $11 million and $12 million of the Partnership’s net income attributable to controlling interests to the Class B units in the three and nine months ended September 30, 2016, respectively, representing the excess of 30 percent of GTN’s distribution over the 2016 threshold level of $20 million.

LIQUIDITY AND CAPITAL RESOURCES

Overview

The Partnership strives to maintain financial strength and flexibility in all parts of the economic cycle. Our principal sources of liquidity and cash flows currently include distributions received from our equity investments, operating cash flows from our subsidiaries public offerings of debt and equity, term loans and our Senior Credit Facility.credit facilities. The Partnership funds its operating expenses, debt service and cash distributions (including those distributions made to TransCanadaTC Energy through our General Partner and as holder of all our Class B units) primarily withfrom operating cash flow. Long-term capital needs may be met through
Overall Current Financial Condition
Cash and Debt position - Our overall long-term debt balance increased by approximately $135 million primarily as result of the financing put in place during the period for our expansion projects. The increase included an incremental $75 million of liquidity from GTN's issuance of long-termSeries A Senior Notes at a fixed rate of 3.12 percent which effectively secured the funding required for GTN XPress for the balance of 2020.
The $75 million liquidity position related to GTN, together with the $24 million return of capital special distribution we received during the third quarter from Iroquois representing our 49.34% share of the reimbursement proceeds received by Iroquois from its terminated Wright Interconnect Project, and net excess cash generated by our solid operating cashflows, resulted in an increase in the balance of our cash and cash equivalents to $253 million at September 30, 2020 compared to our position at December 31, 2019 of approximately $83 million.

36





Working capital position-At September 30, 2020, our current assets totaled $300 million and current liabilities amounted to $499 million, leaving us with a working capital deficit of $199 million compared to a deficit of $14 million at December 31, 2019. Our working capital deficiency is considered normal course for our business and is managed through:
our ability to generate predictable and growing cash flows from operations;
cash on hand and full access to our $500 million Senior Credit Facility; and
our access to debt capital markets, facilitated by our strong investment grade ratings, allowing us the ability to renew and/or equity. Overall,refinance the current portion of our long-term debt.
We continue to be financially disciplined by using our available cash to fund ongoing capital expenditures and maintaining debt at prudent levels and we believe that our pipeline systems’ ability to obtain financing at reasonable rates, together with a history of consistent cash flow from operating activities, provide a solid foundation to meet future liquidity and capital requirements. We expect to be ablewe are well positioned to fund our liquidity requirements, includingobligations as required.
We believe our distributions and required debt repayments, at the Partnership level over the next 12 months utilizing our(1) cash flow and, if required, our existing Senior Credit Facility.

Our Pipeline Systems' Current Financial Condition
The Partnership's source of operating cashflows emanates from (1) operating cash generated by GTN, North Baja, Tuscarora, PNGTS and Bison, our consolidated subsidiaries, and (2) distributions received from our equity investments in Great Lakes, Northern Border and Iroquois.

Our pipeline systems’ principal sources of liquidity are cash generated from operating activities, long-term debt offerings, bank credit facilities and equity contributions from their owners. OurExcept as noted below, our pipeline systems have historically fundedexpect to fund their respective expansion projects primarily with debt. Except as noted below, our pipeline systems' normal recurring operating expenses, maintenance capital expenditures, debt service and cash distributions toare primarily funded with their owners primarily with operating cash flow. However, sinceflows.

Since the fourth quarter of 2010, Great Lakes has funded its debt repayments with cash calls to its owners. Additionally, on September 1, 2017, We contributed approximately $10 million in 2019 and expect our 2020 contribution to be approximately the same.

In August 2019, the Partnership made an equity contribution to Northern BorderIroquois of $83approximately $4 million. This amount representsrepresented the Partnership’s 5049.34 percent share of a one time $166$7 million capital call from Iroquois to cover regulatory costs related to the ExC Project. In 2020, we expect to make an additional contribution request from Northern Borderof approximately $2 million to reducesupport the outstanding balanceExC Project.

Bison’s remaining contracts will continue to be in effect until January of its revolver debt2021. In 2019, Bison generated revenues of $32 million and is expected to increase its available borrowing capacity.

Capitalproduce comparable results in 2020. We continue to explore alternative transportation-related options for Bison and we believe commercial potential exists to allow for the flow of natural gas on Bison in both directions, with the southwest direction involving deliveries onto third party pipelines and ultimately connecting into the Cheyenne hub. In any event, Bison will continue to incur costs related to property tax and operating and maintenance costs of approximately $6 million per year.



Maintenance and expansion capital expenditures are funded by a variety of sources, including cash generated from operating activities, borrowings under bank credit facilities, issuance of senior unsecured notes or equity contributions from our pipeline systems’ owners.as noted above. The ability of our pipeline systems to access the debt capital markets under reasonable terms depends onupon their financial positioncondition and generalprevailing market conditions.


The Partnership’s pipeline systems monitor the creditworthiness of their customers and have credit provisions included in their tariffs which, although limitedgoverned by FERC, allow them to request a certain amount of credit support as circumstances dictate.

Operating Cash Flows

Net cash provided by

The Partnership's operating cashflows for the nine months ended September 30, 2020 compared to the same period in 2019 were lower primarily due to the decrease in distributions received from operating activities decreasedof equity investments, as a result of the following:
• the timing of receipt of Iroquois' third quarter 2019 distributions from its operating activities, which we would ordinarily have received during the fourth quarter of 2019 but were instead received early in the first quarter of 2020 offset by $21additional surplus cash distribution received from Iroquois in the third quarter of 2019 as a result of the cash it accumulated during the previous years' earnings; and
• lower distributions from our equity investment in Northern Border largely due to its higher maintenance capital spending.
Investing Cash Flows
During the nine months ended September 30, 2020, the cash used in our investing activities was a net cash outflow of $136 million compared to a net inflow of $1 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 basis2019 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 2017 period compared to the same period in 2016 primarily due to net effect of:
higher maintenance capital expenditures at GTN for its overhaul projects together with continued capital spending on our GTN XPress, PXP and Westbrook XPress projects;
$24 million return of capital distribution received from Iroquois, representing our 49.34% share of the reimbursement proceeds received by Iroquois from the termination of its Wright Interconnect Project; and
$50 million distribution received from Northern Border during the current 2017 period together with thesecond quarter of 2019 that was considered a return of investment.
Financing Cash Flows
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 investingfor financing activities increased by $541was primarily due to the net debt issuance of $135 million in the nine months ended September 30, 20172020 compared to a net debt repayment of $115 million for 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 2016prior year, primarily due to financing executed for the net effect of:

·    $564 million increase in net issuances of debt in 2017 primarily to finance the 2017 Acquisition;

·    $26 million increase in distributions paid tocapital expenditures on our common unitsGTN XPress, PXP 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;

·    $8 million increase in our ATM equity issuances 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.

Our equity investee Iroquois has $2.8 million of scheduled debt repayments for the remainder of 2017 and Iroquois’ debt repayments are expected to be funded through its cash flow from operations.

December 23, 2020.

Investing Cash Flow Outlook

The Partnership made an equity contribution to Great Lakes of $4$5 million in the first quarter of 2017.2020. This amount represents the Partnership’s 46.45 percent share of a $9an $11 million cash call from Great Lakes to make a scheduled debt

repayment. The Partnership expects to make an additional $5 million equity contribution to Great Lakes in the fourth quarter of 20172020 to further fund debt repayments. This is consistent with prior years.

Our equity investee, Iroquois, has $1.5 million of scheduled debt repayments for the remainder of 2020. Iroquois’ debt repayments are expected to be funded through cash flow from operations.
Our consolidated entities have commitments of $7$92 million as of September 30, 20172020 in connection with various maintenance and general plant projects.

Our

Commercial system purchase effective August 1, 2020
On August 1, 2020, four of our pipelines jointly purchased an internally developed customer-facing commercial natural gas IT application system from a TC Energy affiliate. The total price of the transaction was $51 million and the Partnership's proportionate share was $38 million. The purchase, which is considered a maintenance capital cost, was funded primarily from cash generated from each pipeline's cash from operations. See Note 12 of the “Financial Statements” within Item 1.

Except for the commercial system purchase described above, which is considered maintenance capital, we do not anticipate any other material changes to our expected total2020 growth and maintenance capital expenditures onfrom what was disclosed in our pipeline systems2019 Annual Report. However, those estimates are subject to cost and timing adjustments due to weather, market conditions, permitting conditions and timing of regulatory permits, among other factors, as outlined inwell as additional uncertainty presented by the Management DiscussionCOVID-19 pandemic. We expect to continue funding these expenditures from a combination of (1) cash from operations and Analysis of Financial Condition(2) debt at both the asset and Results of Operations for the year ended December 31, 2016 Consolidated Financial Statements and Notes thereto included as Exhibit 99.3 of the Current Report on Form 8-K filed with the SEC on August 3, 2017 remain materially unchanged.

Debt refinancing:
The Partnership's $350 million aggregate principal amount 4.65 percent Unsecured Senior Notes and $500 million Senior Credit Facility are both due in 2021 and we expect that both will be refinanced or extended prior to maturity.
It is expected that Tuscarora will refinance its maturing Unsecured Term loan through an extension of the existing facility including the potential to increase the size of the facility to include the financing required for Tuscarora XPress.

Non-GAAP Financial Measures: EBITDA, Adjusted EBITDA and Distributable Cash Flow

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

It measures our net income before deducting interest, depreciation and amortization and taxes.

39





Adjusted EBITDA is our EBITDA, less (1) earnings from our equity investments, plus (2) distributions from our equity investment, and plus or minus (3) certain non-recurring items (if any) that are significant but not reflective of our underlying operations.
Beginning the first quarter of 2020, the Partnership revised its calculation of Adjusted EBITDA to include distributions from our equity investments, net of equity earnings from our investments as described above, which were previously excluded from such measure. The presentation of Adjusted EBITDA for the three months and nine months ended September 30, 2019 was recast to conform with the current presentation. The Partnership believes the revised presentation more closely aligns with similar non-GAAP measures presented by our peers and with the Partnership’s definitions of such measures.

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 amountamounts presented.

Total distributable cash flow includes EBITDA plus:

Distributable cash flow is computed net of distributions declared to the General Partner and any distributions allocable to Class B units. Distributions declared to the General Partner are based on its effective two percent interest plus, if applicable, an amount equal to incentive distributions. Distributions allocable to the Class B units in 20172020 equal 30 percent of GTN’s distributable cash flow less $20 million.

Iroquois has no capital commitments of $2 million as of September 30, 2017 relative to procurement of materials on its expansion project.

2020.

Iroquois is restricted under the terms of its note purchase agreement from making cash distributions to its partners unless certain conditions are met. Before a distribution can be made, the debt/debt to capitalization ratio must be below 75%,75 percent and the debt service coverage ratio must be at least 1.25 times for the four preceding quarters. At September 30, 2017,2020, the

debt/ debt to capitalization ratio was 47.6%58.3 percent and the debt service coverage ratio was 8.04 times,6.30 times; therefore, Iroquois was not restricted from making any cash distributions.

Critical Accounting Policies and Estimates

The preparation of financial statements in accordance with GAAP requires us to make estimates and assumptions with respect to values or conditions, which cannot be known with certainty, that affect the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements. Such estimates and assumptions also affect the reported amounts of revenue and expenses during the reporting period. Although we believe these estimates and assumptions are reasonable, actual results could differ. There were no significant changes to the Partnership’s critical accounting estimates during the three and nine months ended September 30, 2017. Information about our critical accounting estimates is included in our Annual Report on Form 10-K for the year ended December 31, 2016.

Our significant accounting policies have remained unchanged since December 31, 2016 except as described in Note 3 within Item 1. “Financial Statements,” of this quarterly report on Form 10-Q. A summary of our significant accounting policies can be found in our audited financial statements and notes thereto for the year ended December 31, 2016 included as exhibit 99.2 in our Current Report on Form 8-Kdated August 3, 2017. (Refer also to Note 2 in Item 1. “Financial Statements” of this Quarterly Report on Form 10-Q).


RELATED PARTY TRANSACTIONS

Please read Notes 6 and 11Note 12 within Item 1. “Financial Statements” for information regarding related party transactions.


Item 3.Quantitative and Qualitative Disclosures About Market Risk

OVERVIEW

The Partnership and our pipeline systems are exposed to market risk, counterparty credit risk, and liquidity risk. Our exposure to market risk discussed below includes forward-looking statements and is not necessarily indicative of actual results, which may not represent the maximum possible gains and losses that may occur, since actual gains and losses will differ from those estimated, based on actual market conditions.

Our primary risk management objective is to mitigate the impact of these risks on earnings and cash flow, and ultimately, unitholder value. We do not use financial instruments for trading purposes.

45





We record derivative financial instruments on the consolidated balance sheet as assets and liabilities at fair value. We estimate the fair value of derivative financial instruments using available market information and appropriate valuation techniques. Changes in the fair value of derivative financial instruments are recognized in earnings unless the instrument qualifies as a hedge and meets specific hedge accounting criteria. Qualifying derivative financial instruments’ gains and losses may offset the hedged items’ related results in earnings for a fair value hedge or be deferred in accumulated other comprehensive income for a cash flow hedge.


MARKET RISK

From time to time, and in order to finance our business and that of our pipeline systems, the Partnership and our pipeline systems issue debt to invest in growth opportunities and provide for ongoing operations. The issuance of floating rate debt exposes the Partnership and our pipeline systems to market risk from changes in interest rates which affect earnings and the value of the financial instruments we hold.

Market risk is the risk that changes in market interest rates may result in fluctuations in the fair values or cash flows of financial instruments. We regularly assess the impact of interest rate fluctuations on future cash flows and evaluate hedging opportunities to mitigate our interest rate risk.

LIBOR, which is set to be phased out at the end of 2021, is used as a reference rate for certain of our financial instruments, including the Partnership’s term loans, revolving credit facilities and the interest rate swap agreements that we use to manage our interest rate exposure. We are reviewing how the expected LIBOR phase-out will affect the Partnership, including the possibility of a delay in adopting a new benchmark due to the uncertainty surrounding the COVID-19 pandemic. We currently do not expect the impact to be material.
As of September 30, 2017,2020, the Partnership’s interest rate exposure resulted from our floating rate Senior Credit Facility, 2015on North Baja’s Unsecured Term Loan Facility, GTN’s Unsecured Term LoanPNGTS’ Revolving Credit Facility and Tuscarora’s Unsecured Term Loan Facility, under which $505$172 million, or 208 percent, of our outstanding debt was subject to variability in LIBOR interest rates. As of Decemberrates (December 31, 2016, the Partnership’s interest rate exposure resulted from our floating rate Senior Credit Facility, 2015 Term Loan Facility, GTN’s Unsecured Term Loan Facility and Tuscarora’s Unsecured Term Loan Facility, under which $4052019 - $112 million or 21 percent of our outstanding debt was subject to variability in LIBOR interest rates.

6 percent).

As of September 30, 2017,2020, the variable interest rate exposure related to our 2013 Term Loan Facility was hedged by fixed interest rate swap arrangements and our effective interest rate was 2.313.26 percent. If interest rates hypothetically increased (decreased) on these facilities by one percent 100(100 basis points,points), compared with rates in effect at September 30, 2017,2020, our annual interest expense would increase (decrease) and net income would decrease (increase) by approximately $5$2 million.

As of September 30, 2017, $162020, $129 million, or 634 percent, of Northern Border’s outstanding debt was at floating rates. If interest rates hypothetically increased (decreased) by one percent 100(100 basis points,points), compared with rates in effect at September 30, 2017,2020, Northern Border’s annual interest expense would increase (decrease) and its net income would decrease (increase) by approximately nil$1 million.

Northern Border’s and Iroquois’ Senior Notes, and all of Great Lakes’ and PNGTS’GTN' s Notes, and the PNGTS Series A Notes issued in October 2020, represent fixed-rate debt;debt, and are therefore they are not exposed to market risk due to floating interest rates. Interest rate risk does not apply to Bison, and North Baja, as they currently doBison does not have any debt.

The Partnership and our pipeline systems use derivatives as part of our overall risk management policy to assist in managing exposures to market risk resulting from these activities within established policies and procedures. We do not enter into derivatives for speculative purposes. Derivative contracts used to manage market risk generally consist of the following:

·

Swaps - contractual agreements between two parties to exchange streams of payments over time according to specified terms.

·

Options - contractual agreements to convey the right, but not the obligation, for the purchaser to buy or sell a specific amount of a financial instrument at a fixed price, either at a fixed date or at any time within a specified period.

The Partnership’sPartnership and our pipeline systems enter into interest rate swaps are structured such thatand option agreements to mitigate the cash flowsimpact of the derivative instruments match those of the variable rate ofchanges in interest on the 2013 Term Loan Facility. The Partnership hedgedrates. For details regarding our current interest payments on the variable-rate 2013 Term Loan Facility with interest rate swaps maturing July 1, 2018, at a weighted average fixed interest rate of 2.31 percent. At September 30, 2017, the fair value of the interest rate swaps accounted for as cash flow hedges was an asset of $2 million (both on a gross and net basis). At December 31, 2016, the fair value of the interest rate swaps accounted for as cash flow hedges was an asset of $1 million and a liability of $1 million (on a gross basis) and an asset of nil million (on a net basis). The Partnership did not record any amounts in net incomeother agreements related to ineffectiveness formitigation of impact on changes in interest rate hedges for the three and nine months ended September 30, 2017 and 2016. The change in fair value of interest rate derivative instruments recognized in other comprehensive income was nil and a gain of $1 million for the three and nine months ended September 30, 2017, respectively (September 30, 2016 — gain of $2 million and a loss of $1 million). For the three and nine months ended September 30, 2017, the net realized loss related to the interest rate swaps was nil, and was included in financial charges and other (September 30, 2016 —$1 million and $2 million).  Refer torates, see Note 1413 within Part I, Item 1. “Financial Statements”.

COMMODITY PRICE RISK

The Partnership has no master netting agreements; however, it has derivative contracts containing provisions with rightsis influenced by the same factors that influence our pipeline systems. None of offset. The Partnership has elected to present the fair value of derivative instruments with the right to offset on a gross basis in the balance sheet. Had the Partnership elected to present these instruments on a net basis, there would be no effect on the consolidated balance sheet as of September 30, 2017 (net asset of nil million as of December 31, 2016).

As discussed in Note 5 within Item 1. Financial Statements, the Partnership’s 2013 Term Loan that was due July 1, 2018, was amended to extend the maturity period through October 2, 2022. As a result of this extension, the Partnership implemented an interest rate hedging strategy during the fourth quarter and hedged the entire $500 million until its October 2, 2022 maturity using forward starting swaps at an average rate of 3.26 percent.

In anticipation of a debt refinancing in 2003, PNGTS entered into forward interest rate swap agreements to hedge the interest rate on its Senior Secured Notes due in 2018. These interest rate swaps were used to manage the impact of interest rate fluctuations and qualified as derivative financial instruments in accordance with ASC 815, Derivatives and Hedging. PNGTS settled its position with a payment of $20.9 million to counterparties at the timeour pipeline systems own any of the refinancing and recorded the realized loss in accumulated other comprehensive income asnatural gas they transport; therefore, they do not assume any of the termination date. The previously recorded loss is currently being amortized against earnings over the life of the PNGTS Senior Secured Notes.  At September 30, 2017, our 61.71 percent proportionate share of net unamortized loss on PNGTS included in other comprehensive income was $1 million (December 31, 2016 - $2 million). For the three and nine months ended September 30, 2017, our 61.71 percent proportionate share of the amortization of realized loss on derivative instruments was nil and $1 million, respectively (September 30, 2016 —nil and $1 million).

OTHER RISKS

related natural gas commodity price risk with respect to transported natural gas volumes.

COUNTERPARTY CREDIT RISK
Counterparty credit risk represents the financial loss that the Partnership and our pipeline systems would experience if a counterparty to a financial instrument failed to meet its obligations in accordance with the terms and conditions of the financial instruments with the Partnership or its pipeline systems.
The Partnership has exposure to counterparty credit risk in the following areas:
cash and cash equivalents;
accounts receivable and other receivables; and
the fair value of derivative assets

At September 30, 2020, we had no significant credit losses, no significant credit risk concentration and no significant amounts past due or impaired. As noted in our 2019 Annual Report, a significant portion of our long-term contract revenues are with counterparties who have an investment grade rating or who have provided guarantees from investment grade parties. Additionally, during the three months and nine months ended September 30, 2020 and at September 30, 2020, no counterparty accounted for more than 10 percent of either our consolidated revenue or accounts receivable.
The Partnership and our pipeline systems have significant credit exposure to financial institutions as they hold cash deposits and provide committed credit lines and critical liquidity in the interest rate derivative market, as well as letters of credit to mitigate exposures to non-creditworthynon-credit worthy customers.
The Partnership closely monitors the creditworthiness of our counterparties, including financial institutions. However, we cannot predict to what extent our business would be impacted by uncertainty in energy commodity prices, including possible declines in our customers’ creditworthiness.

Our maximum counterparty credit exposure with respect to financial instruments at the balance sheet date consists primarily of the carrying amount, which approximates fair value, of non-derivative financial assets, such as accounts receivable, as well as the fair value of derivative financial assets. We review ourinstitutions, reviews accounts receivable regularly and, recordif needed, requests financial assurances in accordance with our pipeline tariffs and records allowances for doubtful accounts using the specific identification method. At September 30, 2017,However, we hadare not incurred any significantable to predict with certainty the extent to which our business could be impacted by the uncertainty surrounding the COVID-19 pandemic or the prolonged impact of low oil prices, including possible declines in our counterparties' creditworthiness.

The factors described above have been incorporated by the Partnership as part of the Measurement of credit losses and had no significant amounts past due or impaired. At September 30, 2017, we hadon financial instruments accounting standard that became effective on January 1, 2020 as described in more detail under Note 3 within Item 1. “Financial Statements.” The Partnership believes the factors as described above are considered to have a credit risk concentration on onenegligible impact considering the portfolio of counterparties held by our customers, Anadarko Energy Services Company, which owed us approximately $4 million and this amount represented greater than 10 percent of our trade accounts receivable.

pipeline assets.

LIQUIDITY RISK
Liquidity risk is the risk that the Partnership and our pipeline systems will not be able to meet our financial obligations as they become due. Our approach to managingWe manage our liquidity risk isby continuously forecasting our cash flow on a regular basis to ensure that we always have sufficientadequate cash balances, cash flow from operations and credit facilities to meet our operating, financing and capital expenditure obligations when due, under both normal and stressed conditions, without incurring unacceptable losses or damageconditions. As discussed previously, global market volatility has heightened and liquidity has tightened but we have taken steps to mitigate our reputation. At September 30, 2017, the Partnership had a Senior Credit Facility of $500 million maturing in 2021risk. Please see "Liquidity and the outstanding balance on this facility was $255 million. In addition, Northern Border had a committed revolving bank line of $200 million maturing in 2020 with $16 million drawn at September 30, 2017. Both the Senior Credit Facility and the Northern Border $200 million credit facility have accordion featuresCapital Resources" within Item 2 for additional capacity of $500 million and $100 million respectively, subject to lender consent.

Item 1A.Risk Factors

The following updated risk factors should be read in conjunction with the risk factors disclosed in Part I, Item 1A. “Risk Factors,” in our 2019 Annual Report.

We face various risks and uncertainties beyond our control, such as recent public health concerns related to the COVID-19 pandemic, which could have a materially adverse impact on our business, financial condition and results of operation.
On March 11, 2020, the WHO declared COVID-19, a global pandemic. In addition, the spread of the COVID-19 virus across the globe has impacted financial markets and global economic activity. These impacts include supply chain disruptions, massive unemployment and a decrease in commercial and industrial activity around the world. The impact of the COVID-19 pandemic, compounded by the recent collapse in crude oil markets, has resulted in significant market disruption.
Our ability to access the debt market or borrowings under our debt agreements to fund our significant capital expenditures could be negatively impacted due to uncertainty in the current market environment. The COVID-19 pandemic could also lead to a general slowdown in construction activities related to our capital projects. However, there is no information available at this time that would allow us to quantify the impact such delay may have on the completion of our capital projects. Finally, if COVID-19 were to impact a location where we have a high concentration of business and resources, our local workforce could be affected by such an occurrence or outbreak which could also significantly disrupt our operations and decrease our ability to service our customers.

While we have not seen any material impact of the COVID-19 pandemic on our business to date, it is difficult to predict how significant the impact of the COVID-19 virus, including any responses to it, will be on the global economy and our business or for how long any disruptions are likely to continue. The extent of such impact will depend on future developments, which are highly uncertain, including new information which may emerge concerning the severity of the COVID-19 pandemic and additional actions which may be taken to contain the further spread of the COVID-19 virus. Even after the COVID-19 pandemic has subsided, our business may be adversely impacted by the economic downturn or a recession that has occurred or may occur in the future. The COVID-19 pandemic could also increase or trigger other risks discussed in our Annual Report on Form 10-K for the year endedyear-ended December 31, 2016.

Following2019, any of which could have a materially adverse impact on our business, financial condition and results of operation.



Prolonged low oil and natural gas prices could result in supply and demand imbalances that impact availability of natural gas for transportation on our pipeline systems.
In early March 2020, the closingmarket experienced a precipitous decline in crude oil prices in response to oil oversupply and demand concerns due to the economic impacts of the 2017 Acquisition, we will not own a controlling interestCOVID-19 pandemic. Additionally, in Iroquois,April 2020, extreme shortages of transportation and we will bestorage capacity caused the New York Mercantile Exchange (NYMEX) West Texas Intermediate oil futures price to go as low as approximately negative $37. This negative pricing resulted from the holders of expiring front month oil purchase contracts being unable to cause certain actionsor unwilling to take place without the agreementphysical delivery of the other partners.

The major policies of Iroquois are established by its management committee, which consists of individuals who are designated by each of the partnerscrude oil and includes one individual designated by us. The management committee requires at least the affirmative vote of a majority of the partners’ percentage interests to take any action. Because of these provisions, without the concurrence of other partners, we would be unable to cause Iroquois to take or not to take certain actions, even though those actions may be in the best interests of the Partnership or Iroquois. Further, Iroquois may seek additional capital contributions. Our funding of these capital contributions would reduce the amount of cash otherwise available for distribution to our unitholders. In the event we elected not to, or were unableaccordingly forced to make payments to purchasers of such contracts in order to transfer the corresponding purchase obligations.

Although oil prices have partially recovered from what was experienced in April, the COVID-19 pandemic and economic downturn could further negatively impact domestic and international demand for crude oil and natural gas and a capital contributionprolonged period of low crude oil and natural gas prices would negatively impact exploration and development of new crude oil and natural gas supplies. In response to Iroquois;the sharp decline in oil and natural gas prices, many producers have announced cuts or suspension of exploration and production activities and some state regulators are considering mandating the proration of production of hydrocarbons. A drilling reduction could impact the availability of natural gas to be transported by our ownership interest would be diluted.

Changes in TransCanada’s costs orpipelines. Sustained low oil and natural gas prices could also impact counterparties’ creditworthiness and their ability to meet their transportation service cost allocation practicesobligations. Such developments could have an adverse effect on our assets, liabilities, business, financial condition, results of operations financial position and cash flows.
