PART I

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;
rates and terms of service;
the refusal or inability of our customers, shippers or counterparties to perform their contractual obligations with us, whether justified or not and whether due to financial constraints ( such as reduced creditworthiness, liquidity issues or insolvency), market constraints, legal constraints (including governmental orders or guidance), the exercise of contractual or common law rights that allegedly excuse their performance (such as force majeure or similar claims) or other factors;
the outcome and frequency of rate proceedings or settlement negotiations on our pipeline systems;
other potential changes in the taxation of master limited partnership (MLP) investments by state or federal governments such as 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), U.S. Environmental Protection Agency (EPA) and U.S. Department of Transportation (DOT);
our ongoing ability to grow distributions through acquisitions, accretive expansions or other growth opportunities, including the timing, structure and closure of further potential acquisitions;
potential conflicts of interest between TC PipeLines GP, Inc., our general partner (General Partner), TC Energy Corporation and us;
failure of the Partnership or our pipeline systems to comply with debt covenants, some of which are beyond our control;
the ability to maintain secure operation of our information technology including management of cybersecurity threats, acts of terrorism and related distractions;
the implementation of future accounting changes and ultimate outcome of commitments and contingent liabilities, if any;
the impact of any impairment charges;
changes in political environment;
operating hazards, casualty losses and other matters beyond our control;

5






the overall increase in the allocated management and operational expenses to our pipeline systems for services performed by TC Energy Corporation;
ability of our pipeline systems to renew rights-of-way at a reasonable cost;
the level of our indebtedness (including the indebtedness of our pipeline systems), increases in interest rates, our level of operating cash flows and the availability of capital;
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; and
uncertainty surrounding the impact of global health crises that reduce commercial and economic activity, including the COVID-19 pandemic, on our business.
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, 2019 (2019 Annual Report) as filed with the SEC on February 21, 2020. All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by these factors. All forward-looking statements are made only as of the date made and except as required by applicable law, we undertake no obligation to update any forward-looking statements to reflect new information, subsequent events or other changes.

TC PIPELINES, LP
CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
NOTE 1    ORGANIZATION
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 TC Energy Corporation (TC Energy Corporation together with its subsidiaries collectively referred to herein as TC Energy), to acquire, own and participate in the management of energy infrastructure assets in North America.

NOTE 2    SIGNIFICANT 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 months ended March 31, 2020 and 2019 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, 2019 included in our 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, 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 2019 Annual Report, except those that became effective in 2020 as described in full under Note 3, "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 as 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.
U.S. federal and certain state income taxes are the responsibility 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 the net income or loss reported in the consolidated statement of operations, is includable in the U.S. federal income tax returns of each partner.
In instances where the Partnership’s consolidated entities are subject to state income taxes, the asset-liability method is used to account for taxes. This method requires recognition of deferred tax assets and liabilities for future tax consequences attributable to the differences between the financial statement carrying amount of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are classified as non-current on 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 3    ACCOUNTING PRONOUNCEMENTS 
Changes in Accounting Policies effective January 1, 2020
Measurement of credit losses on financial instruments
In June 2016, the Financial Accounting Standards Board (FASB) issued new guidance that changes how entities measure credit losses for most financial assets and certain other financial instruments that are not measured at fair value through net income (loss). The new guidance amends 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, 2020 and was applied using a modified retrospective approach. The adoption of this new guidance did not have a material impact on the Partnership’s consolidated financial statements.
Consolidation
In October 2018, the FASB issued new guidance for determining whether fees paid to decision makers and service providers are variable interests for indirect interests held through related parties under common control. This new guidance became effective January 1, 2020, and was applied on a retrospective basis. The adoption of this new guidance did not have a material impact on the Partnership’s consolidated financial statements.

Reference rate reform
In March 2020, in response to the expected cessation of LIBOR,the FASB issued new optional guidance that eases the potential burden of accounting for reference rate reform. The new guidance provides optional expedients for contracts and hedging relationships that are affected by reference rate reform, if certain criteria are met. Each of the expedients 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 4    GOODWILL
Consistent with 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 to be 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 Tuscarora ($23 million) and North Baja ($48 million) acquisitions.
During the first quarter of 2020 there were two major events that impacted financial markets and global economic activity. First, there was an outbreak of a novel strain of coronavirus, COVID-19, which spread around the world and was declared a global pandemic on March 11, 2020 by the World Health Organization (WHO). Second, shortly after the outbreak, the global oil market experienced a precipitous decline in the price of crude oil due to an oversupply of oil coupled with significant demand concerns due to the economic impacts of the COVID-19 pandemic. We believe the current state of the macroeconomic environment 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'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 Tuscarora and North 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 experienced any customer defaults to date and have significant collateral in support of their contracts;

13






multiples and discount rate assumptions used in our quantitative model are reflective of our long-term outlook for Tuscarora and North Baja, in line with their underlying asset life, versus the shorter-term nature of the current situation; and
while we may experience a slowdown in some of our construction activities, the expansion projects associated with these assets are materially on track, and we do not anticipate any significant changes in outlook or delay or inability to proceed due to financing requirements.

As a result of these factors, at March 31, 2020, we believe there is a greater than 50 percent likelihood that both Tuscarora’s and North Baja’s estimated fair values continue to exceed their carrying values. Therefore, no impairment exists on our goodwill. However, adverse changes to our key considerations could result in future impairments on our goodwill.

NOTE 5    EQUITY INVESTMENTS

(a)  No current maturities as of March 31, 2020 and December 31, 2019. At March 31, 2020, Northern Border was in compliance with all its financial covenants.
Great Lakes, a variable interest entity
The Partnership is considered to have a variable interest in Great Lakes, which is accounted for as equity investment since we are not its primary beneficiary. A variable interest entity is a legal entity that either does not have sufficient equity at risk to finance its activities without additional subordinated financial support, 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.
The Partnership made an equity contribution to Great Lakes of $5 million during the three months ended March 31, 2020 (March 31, 2019 - $5 million). This amount represents the Partnership’s 46.45 percent share of an $11 million cash call from Great Lakes to make a scheduled debt repayment.
During the three months ended March 31, 2020, the Partnership received distributions from Great Lakes amounting to $16 million (March 31, 2019 - $17 million).
The Partnership did not have undistributed earnings from Great Lakes for the three months ended March 31, 2020 and 2019.

Iroquois
During the three months ended March 31, 2020, the Partnership received distributions from Iroquois amounting to $27 million (March 31, 2019 - $13 million), which includes the Partnership’s 49.34 percent share of the Iroquois unrestricted cash distribution amounting to approximately $5.2 million (March 31, 2019 - $2.6 million). The unrestricted cash did not represent a distribution of Iroquois’ cash from operations during the period and therefore it was reported as a return of investment in the Partnership’s consolidated statement of cash flows.
The Partnership did not have undistributed earnings from Iroquois for the three months ended March 31, 2020 and 2019.

NOTE 6    REVENUES 
Disaggregation of Revenues
For the three months ended March 31, 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 March 31, 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

17






with customers are recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities.
Contract Balances
All of the Partnership’s contract balances pertain to receivables from contracts with customers amounting to $34 million at March 31, 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.

TC PipeLines, LP 
The Partnership’s senior facility under revolving credit agreement as amended and restated, dated September 29, 2017 (Senior Credit Facility) consists of a $500 million senior revolving credit facility with a banking syndicate, maturing November 10, 2021. In March 2019, the Partnership repaid all amounts outstanding under its Senior Credit Facility and there was no outstanding balance at March 31, 2020 and December 31, 2019.
As of March 31, 2020, the variable interest rate exposure related to the term loan facility under a term loan agreement, as amended, dated September 29, 2017 (2013 Term Loan Facility) was hedged using interest rate swaps at an average rate of 3.26 percent (December 31, 2019 - 3.26 percent). Prior to hedging activities, the London Interbank Offered Rate based (LIBOR) interest rate on the 2013 Term Loan Facility was 2.83 percent at March 31, 2020 (December 31, 2019 - 2.94 percent).
The Senior Credit Facility and the 2013 Term Loan Facility require the Partnership to maintain a debt to adjusted cash flow leverage ratio of no greater than 5.00 to 1.00 for each fiscal quarter, except for the fiscal quarter and the two following fiscal quarters in which one or more acquisitions have been executed, in which case the leverage ratio is to be no greater than 5.50 to 1.00. The leverage ratio was 3.41 to 1.00 as of March 31, 2020.
GTN
GTN’s $100 million 5.29% Unsecured Senior Notes due June 1, 2020 (Unsecured Senior Notes) contain a covenant that limits total debt to no greater than 70 percent of GTN’s total capitalization. GTN’s total debt to total capitalization ratio at March 31, 2020 was 38.7 percent.
GTN’s $100 million 5.29% Unsecured Senior Notes due June 1, 2020 are expected to be refinanced together with additional funding to be used to finance a portion of GTN XPress.

19






PNGTS
PNGTS’ Revolving Credit Facility requires PNGTS to maintain a leverage ratio not greater than 5.00 to 1.00. The leverage ratio was 0.86 to 1.00 as of March 31, 2020. During the three months ended March 31, 2020, PNGTS borrowed an additional $6 million on its Revolving Credit Facility to fund its expansion projects.
The LIBOR-based interest rate applicable to PNGTS’s Revolving Credit Facility was 2.83 percent at March 31, 2020 (December 31, 2019 - 2.99 percent).
Tuscarora
Tuscarora’s $23 million variable rate Unsecured Term Loan due August 1, 2020 (Unsecured Term Loan) contains a covenant that requires Tuscarora to maintain a debt service coverage ratio (cash available from operations divided by the sum of interest expense and principal payments) of greater than or equal to 3.00 to 1.00. As of March 31, 2020, the ratio was 8.63 to 1.00.
The LIBOR-based interest rate applicable to Tuscarora’s Unsecured Term Loan Facility was 2.71 percent at March 31, 2020 (December 31, 2019 - 2.82 percent).
Tuscarora's Unsecured Term Loan is due August 21, 2020 and is expected to be refinanced together with additional funding to be used to finance a portion of Tuscarora XPress.
North Baja
North Baja’s Term Loan Facility contains a covenant that limits total debt to no greater than 70 percent of North Baja’s total capitalization. North Baja’s total debt to total capitalization ratio at March 31, 2020 was 39.99 percent.
The LIBOR-based interest rate applicable to North Baja’s Term Loan Facility was 2.66 percent at March 31, 2020 (December 31, 2019 - 2.77 percent).
Partnership (TC PipeLines, LP and its subsidiaries)
At March 31, 2020, the Partnership was in compliance with all terms and conditions including its financial covenants and its other covenants including restrictions on entering into mergers, consolidations and sales of assets, granting of liens, material amendments to the Fourth Amended and Restated Agreement of Limited Partnership, as amended to date (Partnership Agreement), incurring additional debt and distributions to unitholders.

NOTE 8    PARTNERS’ EQUITY 
Class B units issued to TC Energy
The Class B units entitle TC 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 and (ii) 25 percent of distributions above $20 million 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.

20






For the year ending December 31, 2020, the Class B units’ equity account will be increased by the Class B Distribution, less the Class B Reduction, until such amount is declared for distribution and paid in the first quarter of 2021. During the three months ended March 31, 2020, the 2020 annual Class B Distribution threshold was not exceeded.
For the year ended December 31, 2019, the Class B Distribution was $8 million and was declared and paid in the first quarter of 2020.

NOTE 9    NET INCOME PER COMMON UNIT
Net income per common unit is computed by dividing net income attributable to controlling interests, after deduction of amounts attributable to the General Partner and Class B units, by the weighted average number of common units outstanding.
The amount allocable to the General Partner equals an amount based upon the General Partner’s two 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 2020 will equal 30 percent of GTN’s distributable cash flow during the year ending December 31, 2020 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, 2019 - $20 million less Class B Reduction). During the three months ended March 31, 2020 and 2019, no amounts were allocated to the Class B units as the annual threshold was not exceeded.

NOTE 12    RELATED PARTY TRANSACTIONS
The Partnership does not have any employees. The management and operating functions are provided by the General Partner. The General Partner does not receive a management fee in connection with its management of the Partnership. The Partnership reimburses the General Partner for all costs of services provided, including the costs of employee, officer and director compensation and benefits, and all other expenses necessary or appropriate to conduct the business of, and allocable to, the Partnership. Such costs include (i) overhead costs (such as office space and equipment) and (ii) out-of-pocket expenses related to the provision of such services. The Partnership Agreement provides that the General Partner will determine the costs that are allocable to the Partnership in any reasonable manner determined by the General Partner in its sole discretion. For both the three months ended March 31, 2020 and 2019, total costs charged to the Partnership by the General Partner were $1 million.
As operator of our pipelines, except Iroquois and a certain portion of the PNGTS facilities, TC Energy’s subsidiaries provide capital and operating services to our pipeline systems. TC Energy’s subsidiaries incur costs on behalf of our pipeline systems, including, but not limited to, employee salary and benefit costs, and property and liability insurance costs. Iroquois does not receive any capital and operating services from TC Energy (Refer to Note 5, "Equity Investments").
Capital and operating costs charged to our pipeline systems, except for Iroquois, for the three months ended March 31, 2020 and 2019 by TC Energy’s subsidiaries and amounts payable to TC Energy’s subsidiaries at March 31, 2020 and December 31, 2019 are summarized in the following tables:

Great Lakes
Great Lakes earns significant transportation revenues from TC Energy and its affiliates, some of which are provided at discounted rates and some at maximum recourse rates. For the three months ended March 31, 2020, Great Lakes earned 74 percent of its transportation revenues from TC Energy and its affiliates (March 31, 2019 - 73 percent).
At March 31, 2020, $18 million was included in Great Lakes’ receivables with regard to the transportation contracts with TC Energy and its affiliates (December 31, 2019 - $19 million).
In 2018, Great Lakes executed 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 15-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 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 contract, which has a total 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. The remaining unsubscribed capacity on Great Lakes will be available for contracting in response to developing marketing conditions.

PNGTS
In connection with 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 are required to fulfill future contracts on the PNGTS system. PXP Phases I and II were placed into service on November 1, 2018 and November 1, 2019, respectively. Phase III is anticipated to be in service on November 1, 2020. In the event the expansions are terminated prior to their in-service dates, PNGTS will be required to reimburse its affiliates for any costs incurred related to the development of their facilities. As a result of placing the TC Energy facilities associated with the Phase II volumes in service, PNGTS' obligation to reimburse these development costs has largely been fulfilled. PNGTS is currently obligated to reimburse costs incurred by TC Energy in relation to Phase III, which was approximately $1.5 million at March 31, 2020 and estimated to be approximately $8.6 million by November 1, 2020, when Phase III goes into service.

NOTE 13    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.

23






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 and cash equivalents", "accounts receivable and other", "accounts payable and accrued liabilities", "accounts payable to affiliates" and "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 as Level 2 of the fair value hierarchy for fair value disclosure purposes. Interest rate derivative assets and liabilities are classified as 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 March 31, 2020 and December 31, 2019 was $1,967 million and $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 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 mature on October 2, 2022 and are 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 fixed weighted average interest rate on these instruments is 3.26 percent.
At March 31, 2020, the fair value of the interest rate swaps accounted for as cash flow hedges was a liability of $19 million (both on a gross and net basis) (December 31, 2019 - liability of $6 million), the net change of which is recognized in other comprehensive income. For the three months ended March 31, 2020, the net realized gain related to the interest rate swaps was nil and was included in "financial charges and other" (March 31, 2019 - gain of $1 million) (Refer to Note 15, "Financial Charges and 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 March 31, 2020 and December 31, 2019.

NOTE 16    SUBSEQUENT EVENTS
Management of the Partnership has reviewed subsequent events through May 6, 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.
On April 21, 2020, the board of directors of the General Partner declared the Partnership’s first quarter 2020 cash distribution in the amount of $0.65 per common unit payable on May 12, 2020 to unitholders of record as of May 1, 2020. The declared distribution totaled $47 million and is payable in the following manner: $46 million to common unitholders (including $4 million to the General Partner as a holder of 5,797,106 common units and $7 million to another subsidiary of TC Energy as holder of 11,287,725 common units) and $1 million to the General Partner for its two percent general partner interest. The General Partner did not receive any distributions in respect of its IDRs for the first quarter of 2020.

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 Report.

RECENT BUSINESS DEVELOPMENTS
Current Outlook including the uncertainty surrounding the COVID-19 pandemic and global crude oil prices

On March 11, 2020, the WHO declared COVID-19, a global pandemic. Additionally, amid the COVID-19 crisis, the global oil market experienced a precipitous decline in the price for crude oil due to an oversupply of oil in the first quarter of 2020.

As primary operator of our pipelines, TC Energy’s business continuity plans were put in place across the organization and TC Energy continues to effectively operate our assets, conduct commercial activities and execute on projects with a focus on health, safety and reliability. At the current time, our business is broadly considered an essential or critical business in the United States given the important role our infrastructure plays in delivering energy to North American markets. We anticipate that changes to work practices and other restrictions put in place by government and health authorities in response to the COVID-19 pandemic will have an impact on certain projects. We generally believe this will not be material to our operations, but the long-term impact of the COVID-19 pandemic and associated effects is uncertain at this time.

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 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 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 pronounced changes in the utilization of our assets. While it is too early to ascertain any long-term impact that the COVID-19 pandemic or the oil price decline may have on our capital growth program, we note that we could experience a delay in construction and other related activities.

Capital market conditions in 2020 have been significantly impacted by the COVID-19 pandemic and the oil price decline resulting in periods of heightened volatility and reduced liquidity. Despite this, our liquidity remains strong underpinned by stable cashflow from operations, cash on hand and full access to our $500 million Senior Credit facility. Additionally, we expect to refinance GTN's $100 million Senior Notes due in June 2020 and Tuscarora's $23 million Unsecured Term Loan due in August 2020 together with additional funding to be used to finance a portion of GTN XPress and Tuscarora XPress. 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.

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:
Consistent with GAAP, we evaluate our goodwill related to Tuscarora and North Baja for impairment at least annually and if any indicators of impairment are evident. Our long-lived assets and equity investments on 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:


26






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 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 our long-term outlook for our assets, in line with their underlying asset life, versus the shorter-term nature of the current situation; and
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.

As a result of these factors, at March 31, 2020, we 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.
Other notable Business Developments:
PNGTS’ Portland XPress Project- Phase I and II of this project are in service, and on March 5, 2020, FERC granted PNGTS’ request to begin construction of Phase III of the project. Construction activities are expected to ramp up during the second quarter and PXP is currently on track to be fully in service on November 1, 2020. Once fully in service, all three phases of PXP in aggregate are expected to generate approximately $50 million of annual revenue for PNGTS.

ANR 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 our Great Lakes and TC Energy’s Canadian Mainline systems to connect growing natural gas supply from the WCSB to U.S. Gulf Coast 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) 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.
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 pre-arranged transaction for six agreements with ONEOK Rockies Midstream, L.L.C. and (ii) structuring the pre-arranged transactions 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 (x) unwind the six prearranged contracts, (y) require Northern Border to hold an open season for the capacity such that all interested parties are on equal footing and (z) direct Northern Border to cease from engaging in pre-arranged 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 begin June 1, 2020. Northern Border has filed a motion to consolidate the two complaint dockets and filed its answer to the complaints on May 1, 2020.

Cash Distributions
On April 21, 2020, the board of directors of our General Partner declared the Partnership’s first quarter 2020 cash distribution in the amount of $0.65 per common unit, payable on May 12, 2020 to unitholders of record as of May 1, 2020. The declared distribution totaled $47 million and was payable in the following manner: $46 million to common unitholders (including $4 million to the General Partner as a holder of 5,797,106 common units and $7 million to

27






another subsidiary of TC Energy as a holder of 11,287,725 common units) and $1 million to our General Partner for its two percent general partner interest.

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 ownership interests in eight 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.

Three Months Ended March 31, 2020 compared to the Same Period in 2019
The Partnership’s net income attributable to controlling interests decreased by $5 million in the three months ended March 31, 2020 compared to the same period in 2019, mainly due to the following:
Transmission revenues - The $12 million decrease in transmission revenues was largely the result of the following:
lower revenue on GTN due to (i) its scheduled 6.6 percent rate decrease effective January 1, 2020, (ii) lower discretionary services sold due to moderate weather conditions in early 2020 compared to colder weather experienced in early 2019, and (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;
lower revenue on Tuscarora due to its scheduled 10.8 percent rate decrease effective August 1, 2019;
lower revenue from discretionary services sold by PNGTS in 2020 compared to 2019 due to more moderate weather conditions in early 2020, partially offset by new revenues from Westbrook XPress which went into service on November 1, 2019;
lower volume of discretionary services sold by North Baja; and
lower revenue on Bison as a result of the expiration of one of its legacy contracts at the end of January 2019.
Operation and maintenance expenses - The decrease in operation and maintenance expenses was primarily due to an overall net decrease in property taxes on Bison and PNGTS and an overall decrease in TC Energy's allocated costs related to personnel.
Financial charges and other - The $3 million decrease was primarily attributable to the $68 million reduction in our overall debt balance when compared to our debt balance at March 31, 2019. The reduction was the result of (a) a $50 million prepayment on our 2013 $500 million term loan facility during the second quarter of 2019; (b) a $35 million repayment of GTN's outstanding balance under its unsecured term loan facility during the second quarter of 2019; and (c) a $1 million scheduled payment on Tuscarora's unsecured term loan facility during the third quarter of 2019 offset by (d) $18 million of additional borrowings under PNGTS revolving credit facility.
Net income attributable to non-controlling interests - The $1 million decrease in the Partnership's net income attributable to non-controlling interests was due to the decrease in PNGTS' net income primarily as a result of its lower revenue offset by lower property taxes.

Net Income Attributable to Common Units and Net Income per Common Unit
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 will 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,” for additional disclosures on the Class B units.

LIQUIDITY AND CAPITAL RESOURCES
Overview
Our principal sources of liquidity and cash flows currently include distributions received from our equity investments, operating cash flows from our subsidiaries and our credit facilities. The Partnership funds its operating expenses, debt service and cash distributions (including those distributions made to TC Energy through our General Partner and as holder of all our Class B units) primarily from operating cash flow.
Overall Current Financial Condition
At March 31, 2020, the balance of our cash and cash equivalents of $134 million was higher than our position at December 31, 2019 by approximately $51 million and our overall long-term debt balance increased by approximately $7 million primarily as a result of the financing required during the period on PNGTS' PXP and Westbrook XPress projects.

29






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 we are well positioned to fund our obligations through a prolonged period of disruption, should it occur.
We believe our (1) cash on hand, (2) operating cashflows, (3) $500 million available borrowing capacity on our Senior Credit Facility at May 6, 2020, and (4) if needed, and subject to customary lender's approval upon request, an additional $500 million capacity that is available under the Senior Credit Facility's accordion feature, are sufficient to fund our short-term liquidity requirements, including distributions to our unitholders, ongoing capital expenditures, required debt repayments and other financing needs such as capital contribution requests from our equity investments without the need to issue additional equity.

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 owners. Except as noted below, our pipeline systems are expected to fund operating expenses, capital expenditures, debt service and cash distributions to their owners primarily with operating cash flow.

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

In August 2019, the Partnership made an equity contribution to Iroquois of approximately $4 million. This amount represented the Partnership’s 49.34 percent share of a $7 million capital call from Iroquois to cover costs of regulatory approvals related to their ExC Project. In 2020, we expect to make an additional contribution of approximately $2 million to support the ExC Project.

Bison’s remaining contracts will continue to be in effect until January of 2021. In 2019, Bison generated revenues of $32 million and is expected to produce comparable results in 2020. We are continuing to explore alternative transportation-related options for Bison and we believe commercial potential exists to reverse the direction of natural gas flow on Bison for deliveries onto third party pipelines and ultimately connect into the Cheyenne hub. Notwithstanding the results of these commercial activities, Bison will continue to incur costs related to property tax and operating and maintenance costs of approximately $6 million per year.

Capital expenditures are funded by a variety of sources, as noted above. The ability of our pipeline systems to access the debt capital markets under reasonable terms depends upon their financial condition and prevailing market conditions

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

Operating Cash Flows
In the three months ended March 31, 2020, the Partnership's net cash provided by operating activities decreased by $4 million compared to the same period in 2019 primarily due to the net effect of:
lower net cash flow from operations of our consolidated subsidiaries primarily due to the decrease in their revenue as discussed previously in "Results of Operations" within Item 2;
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 was not received until early in the first quarter of 2020; and
the impact from amount and timing of operating working capital changes.
Investing Cash Flows
During the three months ended March 31, 2020, the cash used in our investing activities was higher by $7 million compared to the same period in 2019 primarily due to the net effect of:
the timing of receipt of Iroquois' third quarter 2019 distributions, a portion of which was considered a return of investment amounting to approximately $2.6 million, which we would ordinarily have received during the fourth quarter of 2019 but was not received until early in the first quarter of 2020; and
the higher capital maintenance expenditures on GTN for its overhaul projects together with continued capital spending on our GTN XPress, PXP and Westbrook XPress projects.
Financing Cash Flows
The Partnership's net cash used for financing activities was approximately $43 million lower in the three months ended March 31, 2020 compared to the same period in 2019 primarily due to the net effect of:
additional borrowings on PNGTS's Revolving Credit Facility of $6 million in 2020 to fund its PXP and Westbrook XPress projects compared to a net debt repayment of $32 million in 2019; and
$5 million decrease in distributions paid to Class B units in 2020 as compared to 2019.


Short-Term Cash Flow Outlook
Operating Cash Flow Outlook
Northern Border declared its March 2020 distribution of $16 million on April 7, 2020, of which the Partnership received its 50 percent share or $8 million. The distribution was paid on April 30, 2020.
Great Lakes declared its first quarter 2020 distribution of $46 million on April 15, 2020, of which the Partnership received its 46.45 percent share or $21 million. The distribution was paid on April 30, 2020.
Iroquois declared its first quarter 2020 distribution of $21 million on May 1, 2020, of which the Partnership will receive its 49.34 percent share or $11 million on June 29, 2020.
Investing Cash Flow Outlook

31






The Partnership made an equity contribution to Great Lakes of $5 million in the first quarter of 2020. This amount represents the Partnership’s 46.45 percent share of an $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 2020 to further fund debt repayments. This is consistent with prior years.
Our equity investee, Iroquois, has $3 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 $29 million as of March 31, 2020 in connection with various maintenance and general plant projects.
We do not anticipate materially revising our expected growth and maintenance capital expenditures for 2020 from what was disclosed in our 2019 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 well as additional uncertainty presented by the COVID-19 pandemic. We expect to continue funding these projects from a combination of (1) cash from operations and (2) debt at both the asset and Partnership levels.

Financing Cash Flow Outlook
Distributions to unitholders
On April 21, 2020, the board of directors of our General Partner declared the Partnership’s first quarter 2020 cash distribution in the amount of $0.65 per common unit payable on May 12, 2020 to unitholders of record as of May 1, 2020. Please see Note 16 of the "Financial Statements" within Item 1 and “Recent Business Developments” within Item 2 for additional disclosures.
Debt refinancing:
The portion of our debt considered current on our balance sheet is expected to be refinanced as follows:
It is expected that GTN will refinance its maturing Unsecured Senior Notes together with additional financing to partially fund the capital costs for GTN XPress.
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 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, which includes net income attributable to non-controlling interests, and earnings from our equity investments. It measures our net income before deducting interest, depreciation and amortization and taxes.
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.
During the three months ended March 31, 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 ended March 31, 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 amounts presented.
Total distributable cash flow includes Adjusted EBITDA:
less:


32






Allowance for funds used during construction (AFUDC);
Interest expense;
Current income taxes;
Distributions to non-controlling interests; and
Maintenance capital expenditures from consolidated subsidiaries.
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 two percent interest plus, if applicable, an amount equal to incentive distributions. Distributions allocable to the Class B units in 2020 equal 30 percent of GTN’s distributable cash flow less $20 million, the residual of which is further multiplied by 43.75 percent and is further reduced by the Class B Reduction. Distributions allocable to the Class B units in 2019 equaled 30 percent of GTN’s distributable cash flow less $20 million and the Class B Reduction.
Distributable cash flow, EBITDA and Adjusted EBITDA are performance measures presented to assist investors in evaluating our business performance. We believe these measures provide additional meaningful information in evaluating our financial performance and cash generating capacity.
The non-GAAP financial measures described above are provided as a supplement to GAAP financial results and are not meant to be considered in isolation or as substitutes for financial results prepared in accordance with GAAP. Additionally, these measures as presented may not be comparable to similarly titled measures of other companies.

Amounts are calculated in accordance with the cash distribution policies of each of our equity investments. Distributions from our equity investments represent our respective share of these entities’ quarterly distributable cash for the current reporting period.
(c) 
This amount represents our proportional 49.34 percent share of the distribution declared by our equity investee, Iroquois, for the current reporting period. For the three months ended March 31, 2019, the amount includes our 49.34 percent share of the Iroquois unrestricted cash distribution amounting to approximately $2.6 million (March 31, 2020- none).
(d) 
Distributions to non-controlling interests represent the respective share of our consolidated entities’ distributable cash not owned by us for the periods presented.
(e) 
The Partnership’s maintenance capital expenditures include expenditures made to maintain, over the long term, the operating capacity, system integrity and reliability of our pipeline assets. This amount represents the Partnership’s and its consolidated subsidiaries’ maintenance capital expenditures and does not include the Partnership’s share of maintenance capital expenditures for our equity investments. Such amounts are reflected in “Distributions from equity investments” as those amounts are withheld by those entities from their quarterly distributable cash.
(f) 
No incentive distributions were declared to the General Partner for both the three months ended March 31, 2020 and 2019.
(g) 
For the three months ended March 31, 2020 and 2019, no distributions were allocated to the Class B units. Please read Notes 8 and 9 within Item 1. “Financial Statements” for additional disclosures on the Class B units.

Three months ended March 31, 2020 Compared to Same Period in 2019
Our EBITDA was lower for the three months ended March 31, 2020 compared to the same period in 2019. The $8 million decrease was primarily due to lower revenue from consolidated subsidiaries as discussed in more detail under the “Results of Operations” section within Item 2.
Our Adjusted EBITDA was lower for the three months ended March 31, 2020 compared to the same period in 2019. The $14 million decrease was primarily due to:
lower revenue from consolidated subsidiaries as discussed in more detail under the “Results of Operations” section within Item 2; and
lower distribution from Iroquois as it satisfied its final surplus cash distribution of $2.6 million per quarter in the fourth quarter of 2019.
Our distributable cash flow decreased by $28 million in the three months ended March 31, 2020 compared to the same period in 2019 due to the net effect of:

lower Adjusted EBITDA;
higher maintenance capital expenditures at GTN as a result of increased spending on major equipment overhauls at several compressor stations and certain system upgrades; and
lower interest expense due to lower average debt balance during the three months ended March 31, 2020 compared to the same period in 2019.

(a) 
Fixed interest rate.
(b) 
Future interest payments on our fixed rate debt are based on scheduled maturities. Future interest payments on floating rate debt are estimated using debt levels and interest rates at March 31, 2020 and are therefore subject to change.
 
The Partnership’s long-term debt results in exposures to changing interest rates. The Partnership uses derivatives to assist in managing its exposure to interest rate risk. Refer to Item 3. “Quantitative and Qualitative Disclosures About Market Risk” for additional information regarding our derivatives.
The fair value of the Partnership’s long-term debt is estimated by discounting the future cash flows of each instrument at estimated current borrowing rates. The estimated fair value of the Partnership’s debt at March 31, 2020 was $1,967 million.
Please read Note 7 within Item 1. “Financial Statements” for additional information regarding the Partnership’s debt.

can be made, the debt/capitalization ratio must be below 75 percent and the debt service coverage ratio must be at least 1.25 times for the four preceding quarters. At March 31, 2020, the debt/capitalization ratio was 52.1 percent and the debt service coverage ratio was 4.25 times; therefore, Iroquois was not restricted from making any cash distributions.

RELATED PARTY TRANSACTIONS
Please read Note 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.
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 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, but we currently do not expect the impact to be material.
As of March 31, 2020, the Partnership’s interest rate exposure resulted from our floating rate on North Baja’s Unsecured Term Loan Facility, PNGTS’ Revolving Credit Facility and Tuscarora’s Unsecured Term Loan Facility, under which $118 million, or 6 percent, of our outstanding debt was subject to variability in LIBOR interest rates (December 31, 2019 - $112 million or 6 percent).
As of March 31, 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 3.26 percent. If interest rates hypothetically increased (decreased) on these facilities by one percent (100 basis points), compared with rates in effect at March 31, 2020, our annual interest expense would increase (decrease) and net income would decrease (increase) by approximately $1 million.
As of March 31, 2020, $115 million, or 32 percent, of Northern Border’s outstanding debt was at floating rates. If interest rates hypothetically increased (decreased) by one percent (100 basis points), compared with rates in effect at

38






March 31, 2020, Northern Border’s annual interest expense would increase (decrease) and its net income would decrease (increase) by approximately $1 million.
GTN’s Unsecured Senior Notes, Northern Border’s and Iroquois’ Senior Notes, and all of Great Lakes’ Notes represent fixed-rate debt, and are therefore not exposed to market risk due to floating interest rates. Interest rate risk does not apply to Bison, as Bison 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 and our pipeline systems enter into interest rate swaps and option agreements to mitigate the impact of changes in interest rates. For details regarding our current interest swaps and other agreements related to mitigation of impact on changes in interest rates, see Note 13 within Part I, Item 1. “Financial Statements,” which information is incorporated herein by reference.

COMMODITY PRICE RISK
The Partnership is influenced by the same factors that influence our pipeline systems. None of our pipeline systems own any of the natural gas they transport; therefore, they do not assume any of the 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 March 31, 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 customers who have an investment grade rating or who have provided guarantees from investment grade parties. Additionally, during the three months ended March 31, 2020 and at March 31, 2020, no customer 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-credit worthy customers.
The Partnership closely monitors the creditworthiness of our counterparties, including financial institutions, reviews accounts receivable regularly and, if needed, records allowances for doubtful accounts using the specific identification method. However, we are not able to predict with certainty the extent to which our business could be impacted by the uncertainty surrounding the COVID-19 pandemic or the impact of low oil prices, including possible declines in our customers' creditworthiness.
The factors described above have been incorporated by the Partnership as part of the Measurement of credit losses on 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 negligible impact considering the portfolio of customers held by our pipeline assets.

39






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. We manage our liquidity risk by continuously forecasting our cash flow on a regular basis to ensure we have adequate 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. Please see "Liquidity and Capital Resources" within Item 2 for more information about our liquidity.

As required by Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (Exchange Act) the management of our General Partner, including the principal executive officer and principal financial officer, evaluated as of the end of the period covered by this report the effectiveness of our disclosure controls and procedures. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. The Partnership’s disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives. Based upon and as of the date of the evaluation, the management of our General Partner, including the principal executive officer and principal financial officer, concluded that the Partnership’s disclosure controls and procedures as of the end of the period covered by this quarterly report were effective to provide reasonable assurance that the information required to be disclosed by the Partnership in the reports that it files or submits under the Exchange Act, is (a) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (b) accumulated and communicated to the management of our General Partner, including the principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure.
Changes in Internal Control Over Financial Reporting
During the quarter ended March 31, 2020, there was no change in the Partnership’s internal control over financial reporting that materially affected or is reasonably likely to materially affect our internal control over financial reporting.

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 recent 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-ended December 31, 2019, 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 market experienced a precipitous decline in crude oil prices in response to oil oversupply and demand concerns due to the economic impacts of the COVID-19 pandemic. Additionally, in April 2020, extreme shortages of transportation and storage capacity caused the 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 or unwilling to take physical delivery of crude oil and accordingly forced to make payments to purchasers of such contracts in order to transfer the corresponding purchase obligations.
The COVID-19 pandemic and economic downturn could further negatively impact domestic and international demand for crude oil and natural gas and a prolonged 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 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 pipelines. Sustained low oil and natural gas prices could also impact shippers’ creditworthiness and their ability to meet their transportation service cost obligations. Such developments could have an adverse effect on our assets, liabilities, business, financial condition, results of operations and cash flow.
