Healthy and  
resilient in  
tough times

A message from Russ and Siim

2  |  TC Energy Annual report 2020

The global healthcare system and economy were tested in new ways in 
2020. We were continuously inspired by the sacrifices made by millions 
of people to support society through all aspects of the COVID-19 
pandemic. To everyone doing their part – thank you.

As we all adapted to changes in lifestyle, TC Energy’s 
people and business remained healthy. The critical role our 
infrastructure plays in providing energy to North America 
meant our services were deemed essential in every 
jurisdiction where we operate. Quietly and reliably, energy 
transported through our systems kept millions of homes, 
hospitals, businesses and other essential services moving 
forward to support people and economies across Canada, 
the U.S. and Mexico. 

As a result, our business remained largely unaffected, even 
during such an extraordinary year. Finding new ways to 
work together, we:

 + Generated record comparable earnings of $3.9 billion or 

$4.20 per common share

 + Reported record comparable funds generated from 

operations of $7.4 billion

 + Reached numerous significant agreements in 

collaboration with our customers

 + Advanced our $20 billion secured capital program and 

 + Placed approximately $5.9 billion of projects into service

These results are a testament to the resourcefulness of 
our 7,500 people, the resilience of our $100 billion asset 
base and our low-risk business model. 

Enduring economic  
and societal value 

We believe in sharing the benefits of our success with 
our stakeholders. In 2020, we worked harder than ever 
to buy locally whenever possible and contributed more 
than $31 million to community organizations across our 
footprint. This included $5.2 million for causes related 
specifically to COVID-19 relief efforts, $8 million for 
Indigenous organizations and $5.4 million directed by 
our workforce to causes that are important to them. 
Our people also found innovative ways to safely log over 
22,500 volunteer hours. 

Through the pandemic, we remained focused on 
our goal of zero safety incidents and progressed our 
operations and projects following COVID-19 protocols 
to keep our people and communities safe. We invested 
more than $14 million in research and development 
activities and advanced over 140 innovation projects 
focused on pipeline safety and reliability, technological 
advancement and sustainability.

We also significantly progressed our sustainability program 
in 2020 and invite you to read our Report on Sustainability 
and visit our online ESG Directory to learn more. Your 
valuable feedback continues to help shape our approach.

Sustainable, predictable  
shareholder returns

For more than two decades, we have remained disciplined 
in our capital allocation model and focused on a long-
term conservative strategy that has delivered consistent 
shareholder returns through all points of the economic 
cycle. We’ve returned approximately 40 per cent of our cash 
flow to shareholders through a strong and growing dividend, 
investing the remaining 60 per cent into complementary 
low-risk assets that continue to drive growth in earnings and 
cash flow per share and enduring shareholder value. 

In 2020, the value of this model was again validated. 
The utility-like nature of our asset base – which 
is approximately 95 per cent rate-regulated and/
or contracted for the long-term with credit-worthy 
counterparties – once again did what it was designed to 
do. For the year ended December 31, 2020, we produced 
record comparable earnings of $4.20 per common 
share, a 1.5 per cent increase compared to 2019, while 
comparable funds generated from operations of  
$7.4 billion were four per cent higher.

Based on the strength of our financial performance in 2020 
and confidence we have in our future, in February 2021 
the Board of Directors increased our quarterly common 
share dividend for the twenty-first consecutive year to 
$3.48 per share on an annualized basis, an increase of 
approximately 7.4 per cent. 

Looking forward, the demand for energy will continue  
to grow and the technology employed will also evolve. 
TC Energy will continue to play a critical role in delivering 
the energy society needs and capture the investment 
opportunities that will certainly arise with increased 
demand and the transition to a lower-carbon future.

Planning for  
our future

Succession planning is an ongoing process at TC Energy, 
and one the Board takes very seriously. For several 
years, the Board has been carefully assessing the skills, 
experience, performance record and personal attributes 
required for the Chief Executive Officer role. When Russ 
announced his intention to retire, we were well prepared 
for a seamless transition.

We have every confidence in François Poirier’s appointment 
to succeed Russ as President and CEO, which became 

4  |  TC Energy Annual report 2020

effective January 1, 2021. François has over 30 years 
of relevant experience and has played a key role on 
our executive leadership team for over five years, with 
involvement in all aspects of our business. He’s shown 
impressive dedication to TC Energy’s long-term success 
and has demonstrated strong vision, leadership and 
commitment to our core values.

While no one could have anticipated the level of 
complexity we would face through the year, excellence 
in leadership requires agility, and both Russ and François 
worked creatively and unwaveringly to ensure a smooth 
transition. It’s an exciting time to guide TC Energy 
forward, and we know François’ integrity, strategic 
thinking, commercial acumen and bottom-line focus will 
serve the company well in the years ahead. 

As our company continues to evolve, so does our Board of 
Directors. We are pleased to welcome Mr. Michael Culbert, 
Ms. Susan Jones and Mr. David MacNaughton, all of  
whom were elected as directors at our 2020 Annual 
Meeting of Shareholders. These three directors bring 
strong leadership and strategy skills to the Board.  
Mr. Culbert has extensive knowledge of the energy industry, 
Ms. Jones has considerable expertise in international 
business operations including legal and regulatory matters 
and Mr. MacNaughton brings significant experience in 
government and policy. They have been excellent additions 
to our Board and we look forward to their ongoing 
contributions to TC Energy in the coming years. 

We would also like to thank Mr. Steve Williams for his service 
to the Board as he will not be standing for re-election this 
year. During his tenure with the Board, Mr. Williams served 
as a member of the Governance committee and Human 
Resources committee where his business acumen provided 
a valuable perspective to the Board.

Looking ahead, the company’s discipline and focus on our 
core priorities will not change. We are confident TC Energy’s 
irreplicable asset base, unmatched human talent and 
outstanding governance and leadership will serve us well in 
the future as it has in the past. 

We thank you for your continued support,

Russ Girling 
President and CEO  
(2010-2020)

Siim A. Vanaselja 
Chair of  
the Board

Three 
complementary 
energy 
infrastructure 
businesses

Natural Gas Pipelines

25% of North 

America’s 
demand

Our 93,400-kilometre (58,000-mile) network 
of natural gas pipelines supplies more than 
25 per cent of the daily clean-burning 
natural gas demand across North America. 
This pipeline network strategically connects 
growing supply in the most prolific basins on 
the continent to key markets across Canada, 
the U.S. and Mexico. We also operate one of 
the continent’s largest natural gas storage 
businesses, with 653 billion cubic feet of 
regulated and non-regulated storage capacity.

Liquids Pipelines

nearly  

3 billion  

barrels delivered safely

Our 4,900-kilometre (3,000-mile) 
liquids pipeline system connects growing 
continental oil supplies to key markets and 
refineries. The Keystone Pipeline System 
delivers approximately 20 per cent of western 
Canadian exports to the U.S. Midwest and 
Gulf Coast, where it is converted into fuel and 
other useful petroleum products.

Power and Storage

4 million+  

homes powered
We own or have interests in seven power 
generation facilities with combined capacity 
of approximately 4,200 megawatts (MW) 
– enough to power more than four million 
homes. Approximately 75 per cent of our 
power capacity is emission-less, and we are 
leaders in the development and operation 
of high-efficiency, natural gas–fired 
generating stations.

The premier energy 
infrastructure company 
in North America,  
now and in the future

A message from François Poirier

6  |  TC Energy Annual report 2020

This is an extremely exciting time for our company and I am honoured to 
take on the role of President and Chief Executive Officer. 

Russ was a visionary leader who added tremendous 
shareholder value. It is my privilege to uphold his culture 
of excellence and mantra of “doing what’s right.” Russ, 
thank you for your invaluable contributions, mentorship 
and diligence. You’ve set us on a great path. 

Progress that matters to  
people and our planet

While 2020 presented some of the greatest global 
challenges in recent history, it was also a year of significant 
advancement in discussions around diversity, inclusion and 
climate change. Society expects its energy to be delivered 
with care for people and our planet. We also demand this 
of ourselves. 

Last year we published 10 new sustainability commitments 
that contribute to the United Nations Sustainable 
Development Goals. We set targets in the areas of 
safety, mental health, community investment, diversity 
and inclusion, and strengthened our commitment to 
enhancing long-term relationships with Indigenous 
communities, landowners, governments and regulators. 

In all our operations and projects, we remain focused on 
managing, reducing or eliminating our GHG emissions 
where possible. Simultaneously, we are undertaking due 
diligence to identify potential paths to maximize our GHG 
emissions reductions by 2050 while ensuring our duty to 
protect shareholder value is not compromised. We are 
confident that we can continue to do both.

Uniquely positioned  
for energy transition

Seventy years ago, the visionaries leading our company saw 
an opportunity to move high-efficiency natural gas across 
our continent from where it was produced in abundance in 
the west to where it was critically needed in the east. As the 
Canadian Mainline was built, lives changed. Solid fuels like 
coal and wood were replaced with a steady, reliable source 
of household heat – high-efficiency natural gas. 

You could say our role in the energy transition began with 
our incorporation in 1951. Since then we’ve garnered even 
more expertise across the energy spectrum including 
liquids, wind, solar, hydro and nuclear. We have also 
dedicated resources to advance and study opportunities 
including pumped storage, hydrogen, waste-heat recovery, 
carbon capture and numerous other energy innovations. 

We believe natural gas and oil will remain critical to the 
global fuel mix for decades to come. Their efficiency, 
reliability and affordability are necessary to support our 
standard of living and backstop the intermittency of 
lower-emission fuel sources. While we continue to watch 
for signposts and test the resiliency of our asset base 
against various energy outlooks, we will adhere to our 
tried-and-tested risk tolerances. 

Whatever pace it takes, the energy transition ahead will 
require expertise and billions of investment dollars. We have 
both. Looking forward, we believe we will be opportunity-
rich and need to carefully allocate our capital to build out an 
ever more modern, robust and responsible energy system.

Strong platform  
for growth

While we were disappointed with the action to revoke 
the Presidential Permit for the Keystone XL pipeline in 
January 2021, our growth platform remains very strong. 
Our system of critical energy infrastructure is expected to 
contribute to the continuous replenishment of our growth 
portfolio in the years ahead. TC Energy’s core business and 
prospects have never been stronger as the world continues 
to consume all types of energy. 

Today, our $20 billion secured capital program includes 
projects that expand and modernize our existing system 
while giving us a clear line of sight to the earnings and 
cash flow it will generate as projects enter service, largely 
between now and 2023. Our capital program includes:

 + Expansions to the NGTL System which are reducing 

western Canada’s reliance on coal

 + Progressing Coastal GasLink which, once complete, will 

displace higher-emission fuel sources in Asia

 + Ongoing upgrades and modernizations that are 

improving efficiency, accessing LNG export points and 
reaching new demand centres across our U.S. natural 
gas pipelines system

 + New and innovative natural gas infrastructure that’s 

displacing fuel oil in Mexico and

 + Growth in our Power and Storage portfolio that includes 

the life extension program at Bruce Power which 
provides emission-less power to Ontario 

Together with a notable portfolio of other similarly 
high-quality opportunities under development, this 
capital program is expected to contribute to strong 
shareholder returns many years into the future. Based on 
the confidence we have in our business plans, we expect 
to grow our common share dividend at an average annual 
rate of five to seven per cent. 

facilities, underscoring our continued access to capital 
markets. Completing the sale of our Ontario natural-gas fired 
power assets and a 65 per cent equity interest in Coastal 
GasLink, in conjunction with project-level credit facilities, 
added to our track record of successfully recycling capital. 

These actions, combined with our substantial internally 
generated cash flow and top credit ratings in our sector, will 
ensure we are able to prudently fund our capital program. 

Strong governance  
and leadership 

A company’s ability to weather even the toughest 
storm is due in large part to the oversight of its Board 
of Directors, and it’s no accident that TC Energy has 
outperformed through times of historic market volatility. 
From the onset of the pandemic, we continued every 
scheduled Board session as planned, engaging in 
robust discussion in a virtual environment and carefully 
overseeing the company’s business and affairs as our 
executive leadership team led us through this difficult 
period. Time and again, this leadership team together 
with our 7,500 people, have demonstrated their technical 
expertise, complementary talents and cohesiveness to 
carefully navigate opportunities and challenges with 
tenacity and innovative thinking. 

I am optimistic about what lies ahead for TC Energy. 
We are uniquely positioned to be the premier energy 
infrastructure company in North America not only today, 
but in the future. Our combination of the right people, 
the right assets and the right opportunities sets the stage 
for us to evolve our business to meet societal needs and 
capture significant shareholder value over the long term. 

I look forward to our continued dialogue and welcome 
your ongoing feedback. 

Sincerely,

Funding our growth 

Because of last year’s market volatility, we took significant 
steps to meaningfully enhance our liquidity and financial 
position. These included issuing long-term debt and 
temporarily establishing incremental committed credit

NON-GAAP MEASURES
This MD&A references the following non-GAAP measures:
• comparable EBITDA
• comparable EBIT
• comparable earnings
• comparable earnings per common share
• funds generated from operations
• comparable funds generated from operations.

These measures do not have any standardized meaning as prescribed by GAAP and therefore may not be comparable to similar 
measures presented by other entities. 

TC Energy Management's discussion and analysis 2020   |  11

Comparable measures
We calculate comparable measures by adjusting certain GAAP measures for specific items we believe are significant but not 
reflective of our underlying operations in the period. Except as otherwise described herein, these comparable measures are 
calculated on a consistent basis from period to period and are adjusted for specific items in each period, as applicable.

Our decision not to adjust for a specific item is subjective and made after careful consideration. Specific items may include:
• gains or losses on sales of assets or assets held for sale
• income tax refunds, adjustments to enacted tax rates and valuation allowances
• certain fair value adjustments relating to risk management activities
• legal, contractual and bankruptcy settlements
• impairment of goodwill, investments and other assets 
• acquisition and integration costs
• restructuring costs.

We exclude the unrealized gains and losses from changes in the fair value of derivatives used to reduce our exposure to certain 
financial and commodity price risks. These derivatives generally provide effective economic hedges, but do not meet the criteria 
for hedge accounting. As a result, the changes in fair value are recorded in net income. As these amounts do not accurately 
reflect the gains and losses that will be realized at settlement, we do not consider them reflective of our underlying operations. 
We also exclude the unrealized foreign exchange gains and losses on the Loan receivable from affiliate as well as the 
corresponding proportionate share of Sur de Texas foreign exchange gains and losses, as these amounts do not accurately reflect 
the gains and losses that will be realized at settlement. These amounts offset within each reporting period, resulting in no 
impact on net income. 

The following table identifies our non-GAAP measures against their most directly comparable GAAP measures.

Comparable EBITDA and comparable EBIT
Comparable EBITDA (comparable earnings before interest, taxes, depreciation and amortization) represents segmented earnings 
adjusted for certain specific items, excluding non-cash charges for depreciation and amortization. We use comparable EBITDA as 
a measure of our earnings from ongoing operations as it is a useful indicator of our performance and is also presented on a 
consolidated basis. Comparable EBIT (comparable earnings before interest and taxes) represents segmented earnings adjusted 
for specific items and is an effective tool for evaluating trends in each segment. Refer to the Financial results sections for each 
business segment for a reconciliation to segmented earnings. 

Comparable earnings and comparable earnings per common share
Comparable earnings represents earnings or losses attributable to common shareholders on a consolidated basis, adjusted for 
specific items. Comparable earnings is comprised of segmented earnings, Interest expense, AFUDC, Interest income and other, 
Income tax expense, Non-controlling interests and Preferred share dividends, adjusted for specific items. Refer to the Financial 
highlights section for reconciliations to Net income attributable to common shares and Net income per common share.

Funds generated from operations and comparable funds generated from operations
Funds generated from operations reflects net cash provided by operations before changes in operating working capital. We 
believe it is a useful measure of our consolidated operating cash flows because it excludes fluctuations from working capital 
balances, which do not necessarily reflect underlying operations in the same period, and is used to provide a consistent measure 
of the cash generating performance of our assets. Comparable funds generated from operations is adjusted for the cash impact 
of specific items noted above. Refer to the Financial condition section for a reconciliation to Net cash provided by operations.

OUR STRATEGY
Our vision is to be the leading energy infrastructure company in North America, focused on pipeline and power generation 
opportunities where we have, or can develop, a significant competitive advantage. 

Our business consists of natural gas and crude oil transportation, storage and delivery systems in addition to power generation 
assets that produce electricity. These long-life infrastructure assets cover strategic North American corridors and are supported 
by long-term commercial arrangements and/or rate regulation, generating predictable and sustainable cash flows and    
earnings – the cornerstones of our low-risk business model. Key components of our strategy, set out below, support our ability to 
be competitive, responsible and innovative, enhance the value proposition for our shareholders and safely deliver the energy 
people need today and in the future.

Key components of our strategy 

1 Maximize the full-life value of our infrastructure assets and commercial positions

• Maintaining safe, reliable operations and ensuring asset integrity, while minimizing environmental impacts, continues to 

be the foundation of our business

• Our pipeline assets include large-scale natural gas and crude oil pipelines and associated storage facilities that connect 

long-life, low cost supply basins with premium North American and export markets, generating predictable and 
sustainable cash flows and earnings

•  Our power and non-regulated storage assets are primarily under long-term contracts that provide stable cash flows and 

earnings.

2

Commercially develop and build new asset investment programs

•  We are developing high quality, long-life assets under our current capital program, comprised of $20 billion in secured 

projects and $8 billion in largely commercially-supported projects under development. These investments will 
contribute incremental earnings and cash flows as they are placed in service

• Our existing extensive footprint offers significant, highly executable in-corridor growth opportunities
•  We continue to develop projects and manage construction risk in a disciplined manner that maximizes capital 

productivity and returns to shareholders

•  As part of our growth strategy, we rely on our experience and our regulatory, commercial, financial, legal and 
operational expertise to successfully permit, fund, build and integrate new pipeline and other energy facilities

•  Safety, executability, profitability and responsible ESG performance are fundamental to our investments.

3

Cultivate a focused portfolio of high-quality development and investment options

•  We assess opportunities to develop and acquire energy infrastructure that complements our existing portfolio, enhances 
future resilience under a changing energy mix, and diversifies access to attractive supply and market regions within our 
risk preferences. Refer to the Enterprise risk management section for an overview of our enterprise risks

•  We focus on commercially regulated and/or long-term contracted growth initiatives in core regions of North America 

and prudently manage development costs, minimizing capital-at-risk in early stages of projects

• We will advance selected opportunities to full development and construction when market conditions are appropriate 

and project risks and returns are acceptable

• We monitor trends specific to energy supply and demand fundamentals, in addition to analyzing how our portfolio 

performs under different energy mix scenarios considering the recommendations of the Financial Stability Board's Task 
Force on Climate-related Financial Disclosures. This contributes to the identification of opportunities that contribute to 
our resilience, strengthen our asset base or improve diversification. 

4 Maximize our competitive strengths

•  We continually seek to enhance our core competencies in safety, operational excellence, investment opportunity 

origination, project execution and stakeholder relations as well as key sustainability and ESG areas to ensure we deliver 
shareholder value. The use of a disciplined approach to capital allocation supports our ability to maximize value over the 
short, medium and long term. A strong focus on talent management ensures that we have the necessary capabilities to 
execute and deliver on our strategy.

TC Energy Management's discussion and analysis 2020   |  15

Our competitive advantage
Decades of experience in the energy infrastructure business, a disciplined approach to project management and a proven capital 
allocation model result in a solid competitive position as we remain focused on our purpose: to deliver the energy people need 
today and in the future, safely, responsibly, collaboratively and with integrity.
• strong leadership and governance: we maintain rigorous governance over our approach to business ethics, enterprise risk 

management, competitive behaviour, operating capabilities and strategy development as well as regulatory, legal, 
commercial, stakeholder and financing support 

• a high-quality portfolio: our low-risk and enduring business model offers the scale and presence to provide essential and 

highly-competitive infrastructure services that enable us to maximize the full-life value of our long-life assets and commercial 
positions throughout all points of the business cycle

• disciplined operations: our values-centred workforce is highly skilled in designing, building and operating energy infrastructure 
with a focus on operational excellence and a commitment to health, safety, sustainability and the environment that is suited 
to both today's environment as well as an evolving energy industry

• financial positioning: we exhibit consistently strong financial performance, long-term stability and profitability, along with a 
disciplined approach to capital investment. We can access sizable amounts of competitively-priced capital to support new 
investment balanced with common share dividend growth while preserving financial flexibility to fund our operations in all 
market conditions. In addition, we continue to maintain the simplicity and understandability of our business and corporate 
structure

• proven ability to adapt: we have a long track record of turning policy and technology changes into opportunities – for 

example, re-entering Mexico when the country shifted from fuel oil to natural gas, reversing pipeline flows in response to the 
shale gas revolution and re-purposing the underutilized Canadian Mainline pipeline capacity from natural gas to crude oil 
service

• commitment to sustainability and ESG: we take a long-term view to managing our interactions with the environment, 

Indigenous groups, community members and landowners. We aim to communicate transparently on sustainability-related 
topics with all stakeholders and recently published 10 sustainability commitments as part of our 2020 Report on Sustainability, 
which support the United Nations Sustainable Development Goals

• open communication: we carefully manage relationships with our customers and stakeholders and offer clear, candid 

communication of our prospects to investors in order to build trust and support.

Our risk preferences
The following is an overview of our risk philosophy:

Live within our means

• Rely on internally-generated cash flows, existing debt capacity, partnerships and portfolio management to finance new 

initiatives. Reserve issuing common equity for transformational opportunities.

Project risks known and acceptable

• Select investments with known, acceptable and manageable project execution risk, including stakeholder considerations.

Business underpinned by strong fundamentals

• Invest in assets that are investment-grade on a stand-alone basis, with stable cash flows, supported by strong underlying 

macroeconomic fundamentals, conducive regulation and/or long-term contracts with creditworthy counterparties.

Manage credit metrics to ensure "top-end" sector ratings

• Solid investment-grade ratings are an important competitive advantage and TC Energy will seek to ensure our credit profile 

remains at the top-end of the midstream sector while balancing the interests of equity and fixed income investors.

Prudent management of counterparty exposure

• Limit counterparty concentration and sovereign risk; seek diversification and solid commercial arrangements underpinned by 

strong fundamentals.

COVID-19
On March 11, 2020, the World Health Organization declared the novel coronavirus, or COVID-19, a global pandemic. Company 
business continuity plans remain in place across our organization and we continue to effectively operate our assets, conduct 
commercial activities and execute on projects with a focus on health, safety and reliability. Our businesses are broadly 
considered essential in Canada, the United States and Mexico given the important role our infrastructure plays in providing 
energy to North American markets. We are confident that our robust continuity and business resumption plans for critical teams, 
including natural gas, liquids and power plant control as well as commercial and field operations, will continue to ensure the safe 
and reliable delivery of energy for our customers. 

With approximately 95 per cent of our comparable EBITDA generated from rate-regulated assets and/or long-term contracts, we 
are largely insulated from the short-term volatility associated with fluctuations in volume throughput and commodity prices. 
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, with the exception of the Keystone Pipeline System which has experienced a reduction in 
uncontracted volumes that we expect to remain until market conditions rebalance and normalize. As well, we have not 
encountered any significant impacts on our supply chain. 

In March 2020, as a result of COVID-19 impacts, Bruce Power declared force majeure with respect to its Unit 6 Major Component 
Replacement (MCR) and certain Asset Management work. While the MCR and Asset Management activities continue to progress, 
the ultimate impact of the Unit 6 force majeure at Bruce Power will depend on the extent and duration of the pandemic and 
their ability to implement mitigation measures throughout the project. In December 2020, the Government of British Columbia 
issued an order limiting the presence of construction personnel in Northern British Columbia. This order will have an impact on 
2021 planned construction for the Coastal GasLink pipeline project (Coastal GasLink). The extent of the ultimate impact will 
depend on the duration of the restrictions. While it is too early to ascertain any long-term impact that COVID-19 may have on our 
capital program, in addition to the impacts on Bruce Power Unit 6 MCR and Coastal GasLink construction, directionally we have 
observed some slowdown of our construction activities and capital expenditures in 2020. This is largely due to permitting delays 
as regulators have been unable to process permits and conduct consultations within timeframes that were originally anticipated. 

Capital market conditions in 2020 saw periods of extreme volatility and reduced liquidity. Despite this challenging backdrop, we  
were able to enhance our liquidity by continuing to access debt capital markets, completing sizable portfolio management 
transactions and arranging incremental committed credit facilities, which were extinguished in fourth quarter 2020 as they were 
no longer required. With the combination of our predictable and growing cash flows from operations, cash on hand, substantial 
committed credit facilities and various other financing levers available to us, we believe we are well positioned to continue to 
fund our obligations, including in the event similarly challenging market conditions re-emerge.

The combination of the COVID-19 pandemic and the unparalleled energy demand and supply disruption has had a significant 
impact on certain of our customers. While counterparty risk has heightened and the long-term impacts of COVID-19 and related 
disruptions on our customers are difficult to predict, we are not expecting a material negative impact to our 2021 earnings or 
cash flows as a result of this increased risk. 

Since the pandemic began, we have endeavored to understand and respond to the requirements of the communities in which 
we operate. Based on the paramount needs of people in our communities, our support has focused on food security and first 
responder organizations. As our multi-billion dollar capital projects continue to progress, where possible, we continue to focus 
on buying and hiring locally, benefiting small businesses and creating jobs in many communities that have been significantly 
impacted by the COVID-19 crisis. 

The full extent and lasting impact of the COVID-19 pandemic on the global economy is as yet undetermined but to date has 
included extreme volatility in financial markets and commodity prices, a significant reduction in overall economic activity, 
widespread extended shutdowns of businesses and supply chain disruptions. The degree to which COVID-19 has a more 
pronounced longer-term impact on our operations and growth projects will depend on future developments, policies and 
actions, all of which remain highly uncertain. Additional information regarding the risks, uncertainties and impact on our 
business from COVID-19 can be found throughout this MD&A including the Capital program, Outlook, Significant events within 
each business segment, Financial condition and Financial risks sections.

CAPITAL PROGRAM
We are developing quality projects under our capital program. These long-life infrastructure assets are supported by long-term 
commercial arrangements with creditworthy counterparties and/or regulated business models and are expected to generate 
significant growth in earnings and cash flows.

Our capital program consists of $20 billion of secured projects which include commercially supported, committed projects that 
are either under construction or are in or preparing to commence the permitting stage. An additional $8 billion of projects under 
development are commercially supported (except where noted) but have greater uncertainty with respect to timing and 
estimated project costs and are subject to certain key approvals. 

Three years of maintenance capital expenditures for our businesses are included in the secured projects table. Maintenance 
capital expenditures on our regulated Canadian and U.S. natural gas pipelines are added to rate base on which we have the 
opportunity to earn a return and recover these expenditures through current or future tolls, which is similar to our capacity 
capital projects on these pipelines. Tolling arrangements in our liquids pipelines business provide for the recovery of 
maintenance capital expenditures.

In the year ended December 31, 2020, we placed approximately $5.9 billion of capacity capital projects in service, mainly 
comprised of NGTL System expansions. In addition, approximately $1.8 billion of maintenance capital expenditures were 
incurred.

All projects are subject to cost and timing adjustments due to weather, market conditions, route refinement, permitting 
conditions, scheduling and timing of regulatory permits, among other factors as well as the additional restrictions and 
uncertainty presented by the ongoing impact of COVID-19. Amounts included in the following tables exclude capitalized interest 
and AFUDC.

Estimated project costs for 2022 and 2023 include $0.5 billion for the Foothills pipeline system related to the 2023 West Path Expansion Program.
On May 22, 2020, we sold a 65 per cent equity interest in Coastal GasLink Pipeline Limited Partnership and began to account for our remaining 35 per cent 
investment using equity accounting. As a result, the estimated project cost and carrying value represent our share of partner equity contributions to the 
project, with the expected in-service date and estimated project cost reflecting the last project update. Refer to the Canadian Natural Gas Pipelines - Significant 
events section for additional information regarding the ongoing review of project cost and schedule.
Construction of the central segment of the Tula project has been delayed due to a lack of progress to successfully complete Indigenous consultation by the 
Secretary of Energy. Project completion is expected approximately two years after the consultation process is successfully concluded. The East Section of the 
Tula pipeline is available for interruptible transportation services.
Advancement of the Keystone XL project has been suspended pending assessment of the implications and options available to us following the                   
January 20, 2021 revocation of the Presidential Permit and an asset impairment is expected to be recorded in first quarter 2021. The Keystone XL project carrying 
value reflects the amount remaining after the 2015 impairment charge, along with additional amounts expended and capitalized since January 2018. A portion 
of the carrying value has been funded by Government of Alberta contributions or is subject to recovery from shippers under contract. Refer to the

2020 FINANCIAL HIGHLIGHTS
We use certain financial measures that do not have a standardized meaning under GAAP because we believe they improve our 
ability to compare results between reporting periods and enhance understanding of our operating performance. Known as       
non-GAAP measures, they may not be comparable to similar measures provided by other companies. 

Comparable EBITDA, comparable earnings, comparable earnings per common share and comparable funds generated from 
operations are all non-GAAP measures. Refer to page 11 for more information about the non-GAAP measures we use and pages 24

Net income attributable to common shares in 2020 was $4.5 billion or $4.74 per share (2019 – $4.0 billion or $4.28 per share; 
2018 – $3.5 billion or $3.92 per share). Net income per common share increased by $0.46 per share in 2020 compared to 2019 
and $0.36 in 2019 compared to 2018 due to the increases in net income and reflects the dilutive impact of common shares issued 
under our DRP in 2019 and 2018 and Corporate ATM program in 2018.

The following specific items were recognized in net income attributable to common shares and were excluded from comparable 
earnings in the relevant periods:
2020
• an after-tax gain of $402 million related to the sale of a 65 per cent equity interest in Coastal GasLink Pipeline Limited 

Partnership (Coastal GasLink LP)

• income tax valuation allowance releases of $299 million primarily related to the reassessment of deferred tax assets that were 
deemed more likely than not to be realized as a result of our March 31, 2020 decision to proceed with the Keystone XL project. 
Refer to the Liquids Pipelines - Significant events section for additional information

• an additional $18 million income tax recovery related to state income taxes on the sale of certain Columbia Midstream assets
• an after-tax loss of $283 million related to the Ontario natural gas-fired power plant assets sold on April 29, 2020. The total

Comparable EBITDA – 2020 versus 2019
Comparable EBITDA in 2020 decreased by $15 million compared to 2019 primarily due to the net result of the following:
• decreased earnings from Liquids Pipelines as a result of lower volumes on the Keystone Pipeline System, reduced contributions 

from liquids marketing activities and the July 2019 sale of an 85 per cent equity interest in Northern Courier 

• lower Power and Storage results mainly attributable to decreased Bruce Power results in 2020 primarily due to the net impact 
of lower overall plant generation with the commencement of the Unit 6 MCR program on January 17, 2020, partially offset by 
fewer outage days on the remaining units and a higher realized power price. As well, reduced earnings in Canadian Power in 
2020 were largely as a result of the sale of our Ontario natural gas-fired power plants on April 29, 2020 and the May 2019 sale 
of our Coolidge generating station 

• higher comparable EBITDA from Canadian Natural Gas Pipelines primarily due to the impact of increased rate-base earnings 

and flow-through depreciation from additional facilities placed in service as well as higher flow-through financial charges on 
the NGTL System, plus Coastal GasLink development fee revenue recognized in 2020, partially offset by lower flow-through 
income taxes on the NGTL System and the Canadian Mainline

• increased contribution from Mexico Natural Gas Pipelines mainly due to higher earnings from our investment in the                
Sur de Texas pipeline following its September 2019 in-service. This includes revenues of US$55 million recognized in first 
quarter 2020 related to fees associated with our successful construction of Sur de Texas

• incremental earnings in U.S. Natural Gas Pipelines from Columbia Gas and Columbia Gulf growth projects placed in service and 
from ANR due to the sale of natural gas from certain gas storage facilities, partially offset by decreased earnings as a result of 
the sale of certain Columbia Midstream assets in August 2019

• foreign exchange impact of a stronger U.S. dollar on the Canadian dollar equivalent earnings from our U.S. dollar-

denominated operations.

Comparable EBITDA – 2019 versus 2018
Comparable EBITDA in 2019 increased by $803 million compared to 2018 primarily due to the net result of the following:
• increased contribution from U.S. Natural Gas Pipelines mainly attributable to incremental earnings from Columbia Gas and 

Columbia Gulf growth projects placed in service, partially offset by decreased earnings from Bison (wholly owned by                
TC PipeLines, LP) contract terminations and from the sale of certain Columbia Midstream assets in August 2019

• increased contribution from Liquids Pipelines primarily resulting from higher volumes on the Keystone Pipeline System and 

earnings from liquids marketing activities, partially offset by decreased earnings as a result of the sale of an 85 per cent equity 
interest in Northern Courier in July 2019

• higher contribution from Power and Storage primarily attributable to increased Bruce Power results from a higher realized 
power price, partially offset by the sale of our interests in the Cartier Wind power facilities in late 2018 and the sale of the 
Coolidge generating facility in May 2019 

• lower contribution from Canadian Natural Gas Pipelines mainly due to lower flow-through income taxes on the Canadian 

Mainline reflecting the impact of the Canadian Mainline 2018-2020 Tolls Review (NEB 2018 Decision) and on the NGTL System 
as a result of accelerated tax depreciation enacted by the Canadian Federal Government, partially offset by higher rate-base 
earnings and depreciation on the NGTL System as additional facilities were placed in service

• foreign exchange impact of a stronger U.S. dollar on the Canadian dollar equivalent earnings from our U.S. dollar-

denominated operations.

Due to the flow-through treatment of certain expenses, including income taxes and depreciation on our Canadian                   
rate-regulated pipelines, the accelerated tax depreciation changes in 2019 and increased depreciation expense impacts our 
comparable EBITDA despite having no significant effect on net income.

Comparable earnings – 2020 versus 2019
Comparable earnings in 2020 were $94 million or $0.06 per common share higher than in 2019, and were primarily the net result 
of:
• changes in comparable EBITDA described above
• a decrease in income tax expense mainly due to lower flow-through income taxes on Canadian rate-regulated pipelines and 

the impact of higher foreign tax rate differentials

• lower interest expense as a result of higher capitalized interest largely related to Keystone XL, net of the impact of Napanee 

completing construction in first quarter 2020, and lower interest rates on reduced levels of short-term borrowings. These were 
partially offset by the effect of long-term debt issuances, net of maturities, as well as the foreign exchange impact from a 
stronger U.S. dollar on the translation of U.S. dollar-denominated interest

• a decrease in AFUDC predominantly due to NGTL System expansions placed in service and the suspension of recording AFUDC 
on the Tula project resulting from continued construction delays, partially offset by further construction of the Villa de Reyes 
pipeline

• higher depreciation largely in Canadian Natural Gas Pipelines and U.S. Natural Gas Pipelines reflecting new assets placed in 
service. In Canadian Natural Gas Pipelines, however, it is fully recovered in tolls on a flow-through basis as discussed in 
comparable EBITDA above, and therefore has no significant impact on comparable earnings.

26  |   TC Energy Management's discussion and analysis 2020

Comparable earnings – 2019 versus 2018
Comparable earnings in 2019 were $371 million or $0.28 per common share higher than in 2018, and were primarily the net result 
of:
• changes in comparable EBITDA described above
• higher income tax expense due to increased comparable earnings before income taxes and lower foreign tax rate differentials, 
partially offset by lower flow-through income taxes on the Canadian Mainline reflecting the impact of the NEB 2018 Decision 
and on the NGTL System from the effect of accelerated tax depreciation

• higher depreciation largely in Canadian Natural Gas Pipelines, which is subject to flow-through treatment, and U.S. Natural 

Gas Pipelines, both reflecting new projects placed in service 

• increased interest expense primarily as a result of long-term debt issuances, net of maturities, the foreign exchange impact on 

translation of U.S. dollar-denominated interest and higher levels of short-term borrowings, partially offset by higher 
capitalized interest

• lower AFUDC primarily due to Columbia Gas and Columbia Gulf growth projects placed in service, partially offset by capital 

expenditures on our NGTL System and continued investment in our Mexico projects.

Comparable earnings per share reflected the dilutive impact of common shares issued under our DRP in 2019 and 2018, and 
Corporate ATM program in 2018. Refer to the Financial condition section of this MD&A for further information on common share 
issuances. 

Cash flows
Net cash provided by operations of $7.1 billion in 2020 remained consistent with 2019, and comparable funds generated from 
operations of $7.4 billion were four per cent higher in 2020 compared to 2019, primarily due to the collection of fees related to 
the construction of Sur de Texas and Coastal GasLink, the recovery of higher depreciation on the NGTL System and higher 
comparable earnings, partially offset by lower distributions from the operating activities of our equity investments.

Capital spending includes capacity capital expenditures, maintenance capital expenditures, capital projects in development and contributions to equity 
investments.

In 2020 and 2019, we invested $8.9 billion and $8.8 billion, respectively, in capital projects to maintain and optimize the value of 
our existing assets and to develop new, complementary assets in high-demand areas. Our total capital spending in 2020 and 
2019 included contributions of $0.8 billion and $0.6 billion, respectively, to our equity investments, predominantly related to 
Bruce Power.

Proceeds from sales of assets
In 2020, we completed the following portfolio management transactions. All cash proceeds amounts are prior to income tax and 
post-closing adjustments:
• the sale of a 65 per cent equity interest in Coastal GasLink LP for proceeds of $656 million
• the sale of our Ontario natural gas-fired power plants for net proceeds of approximately $2.8 billion.

In addition to the proceeds from the above transactions, in 2020, we received a $1.5 billion distribution from a Coastal GasLink LP 
project-level credit facility draw which preceded the equity sale.

In 2019, we completed the following portfolio management transactions. All cash proceeds amounts are prior to income tax and 
post-closing adjustments:
• the sale of certain Columbia Midstream assets for proceeds of approximately US$1.3 billion
• the sale of the Coolidge generating station for proceeds of US$448 million
• the sale of an 85 per cent equity interest in Northern Courier for proceeds of $144 million. 

In addition to the proceeds from the above transactions, in 2019, we received a $1.0 billion distribution from a Northern Courier 
debt issuance which preceded the equity sale.

Balance sheet
We continue to maintain a solid financial position while growing our total assets by $1.0 billion in 2020. At December 31, 2020, 
common shareholders' equity, including non-controlling interests, represented 35 per cent (2019 – 35 per cent) of our capital 
structure, while other subordinated capital, in the form of junior subordinated notes, redeemable non-controlling interest and 
preferred shares, represented an additional 16 per cent (2019 – 16 per cent). Refer to the Financial condition section for more 
information about our capital structure.

Dividends 
We increased the quarterly dividend on our outstanding common shares by 7.4 per cent to $0.87 per common share for the 
st
quarter ending March 31, 2021 which equates to an annual dividend of $3.48 per common share. This was the 21
 consecutive 
year we have increased the dividend on our common shares and is consistent with our goal of growing our common share 
dividend at an average annual rate of five to seven per cent.

Dividend reinvestment plan
Under the DRP, eligible holders of common and preferred shares of TC Energy can reinvest their dividends and make optional 
cash payments to obtain additional TC Energy common shares. From July 1, 2016 to October 31, 2019, participation was satisfied 
through common shares issued from treasury at a discount of two per cent to market prices over a specified period. 

Commencing with the dividends declared October 31, 2019, common shares purchased with reinvested cash dividends under     
TC Energy’s DRP are instead acquired on the open market at 100 per cent of the weighted average purchase price. The DRP is 
available for dividends payable on TC Energy's common and preferred shares.

OUTLOOK

Comparable earnings
Our 2021 comparable earnings per common share are expected to be generally consistent with 2020 considering the net impact 
of the following:
• growth in the NGTL System and increased incentive earnings from the Canadian Mainline
• increased Coastal GasLink development fee revenue due to an expected increase in project activity
• an increase in transportation rates on Columbia Gas that is dependent on the outcome of the Section 4 Rate Case filed with 

FERC 

• a full-year impact from assets placed in service in 2020 and new projects to be placed in service in 2021

Offset by:
• reduced capitalized interest due to the revocation of the Keystone XL Presidential Permit and resulting suspension of the 

advancement of the project

• continuing lower uncontracted volumes on the Keystone Pipeline System and reduced margins in the liquids marketing 

business 

• lower contribution from Bruce Power as a result of greater planned outage days and higher operating costs
• the sale of our Ontario natural gas-fired power plants in 2020
• fees recognized in 2020 associated with the construction of the Sur de Texas pipeline
• suspension of AFUDC on Villa de Reyes.

We will continue to monitor the impact that COVID-19 may have on energy markets, our construction projects and regulatory 
proceedings and the potential effect on our 2021 comparable earnings per share.

In addition to the items noted above, a non-cash impairment on the Keystone XL project is expected to be recorded in first 
quarter 2021, which will be excluded from comparable earnings.

Consolidated capital spending and equity investments
We expect to spend approximately $7 billion in 2021 on growth projects, maintenance capital expenditures and contributions to 
equity investments. The majority of the 2021 capital program is attributable to spending on NGTL System expansions,               
U.S. Natural Gas Pipelines projects, the Bruce Power life extension program and normal course maintenance capital 
expenditures. We do not believe disruptions related to COVID-19 will be material to our overall 2021 capital program but 
recognize that uncertainty exists in both the short and longer term. 

Refer to the relevant business segment and Financial condition outlook sections for additional details on expected earnings and 
capital spending for 2021.

NATURAL GAS PIPELINES BUSINESS
Our natural gas pipeline network transports natural gas from supply basins to local distribution companies, power generation 
plants, industrial facilities, interconnecting pipelines, LNG export terminals and other businesses across Canada, the U.S. and 
Mexico. Our network of pipelines taps into most major supply basins and transports over 25 per cent of continental daily natural 
gas needs through: 
• wholly-owned natural gas pipelines – 81,500 km (50,640 miles) 
• partially-owned natural gas pipelines – 11,921 km (7,407 miles).

In addition to our natural gas pipelines, we have regulated natural gas storage facilities in the U.S. with a total working gas 
capacity of 535 Bcf, making us one of the largest providers of natural gas storage and related services to key markets in 
North America. 

Our Natural Gas Pipelines business is split into three operating segments representing its geographic diversity: Canadian Natural 
Gas Pipelines, U.S. Natural Gas Pipelines and Mexico Natural Gas Pipelines. 

Strategy
Optimizing the value of our existing natural gas pipeline systems, while responding to the changing flow patterns of natural gas 
in North America, is a top priority. We also pursue new pipeline opportunities to add incremental value to our business.

Our key areas of focus include:
• primarily in-corridor expansion and extension of our existing large North American natural gas pipeline footprint
• connections to new and growing industrial and electric power generation markets and LDCs 
• expanding our systems in key locations and developing new projects to provide connectivity to LNG export terminals, both 
operating and proposed, along the U.S. Gulf Coast; the west coast of the U.S., Mexico and Canada; and the east coast of 
Canada

• connections to growing Canadian and U.S. shale gas and other supplies.

Each of these areas plays a critical role in meeting the transportation requirements for supply of and demand for natural gas in 
North America.

Recent highlights

Canadian Natural Gas Pipelines
• approximately $3.5 billion of projects placed in service in 2020 including the $1.1 billion Aitken Creek section of the $1.6 billion 

North Montney project in service on January 31, 2020. The final section of pipeline went into service May 1, 2020

• completed the sale of a 65 per cent equity interest in Coastal GasLink LP for net proceeds of $656 million and entered into a 

project-level credit facility with a current total capacity of $6.8 billion 

• CER approved a five-year negotiated settlement on the NGTL System (NGTL System 2020-2024 Settlement)
• all elements of the NGTL System Rate Design and Services Application were approved by the CER as filed
• CER recommended and Governor in Council (GIC) approved the 2021 NGTL System Expansion Program
• CER approved a six-year negotiated settlement on the Canadian Mainline (Mainline 2021-2026 Settlement).

U.S. Natural Gas Pipelines
• placed in service approximately US$1.9 billion of projects including completion of the capital spend on the Columbia Gas 

Modernization II program

• Columbia Gas filed a Section 4 Rate Case with FERC on July 31, 2020 requesting an increase to maximum transportation rates 

effective February 1, 2021, subject to refund. The rate case is progressing as expected as we continue to pursue a collaborative 
process through settlement negotiations.

Mexico Natural Gas Pipelines
• completed the Guadalajara pipeline flow reversal project and renegotiated the TSA with the CFE enabling bidirectional flows 

connecting LNG imports and continental natural gas to regional markets

• continued construction of the Villa de Reyes pipeline project with in-service expected in 2021
• assets performed with 100 per cent reliability and asset utilization continued to increase.

UNDERSTANDING OUR NATURAL GAS PIPELINES BUSINESS
Natural gas pipelines move natural gas from major sources of supply to locations or markets that use natural gas to meet their 
energy needs.

Our natural gas pipelines business builds, owns and operates a network of natural gas pipelines across North America that 
connects gas production to interconnects, end-use markets and LNG export terminals. The network includes underground 
pipelines that transport natural gas predominantly under high pressure, compressor stations that act like pumps to move large 
volumes of natural gas along the pipeline, meter stations that record the amount of natural gas coming on the network at 
receipt locations and leaving the network at delivery locations, and regulated natural gas storage facilities that provide services 
to customers and help maintain the overall balance of the pipeline systems. 

Our major pipeline systems
The Natural Gas Pipelines map on page 34 shows our extensive pipeline network in North America that connects major supply 
sources and markets. The highlights shown on the map include:

Canadian Natural Gas Pipelines

NGTL System: This is our natural gas gathering and transportation system for the WCSB, connecting most of the natural gas 
production in western Canada to domestic and export markets. We believe we are well positioned to connect growing supply in 
northeast B.C. and northwest Alberta. Our large capital program for new pipeline facilities is driven by these two supply areas, 
along with growing demand for intra-Alberta firm transportation for electric power generation conversion from coal, oil sands 
development and petro-chemical feedstock as well as to our major export points at the Empress and Alberta/B.C. delivery 
locations. The NGTL System is also well positioned to connect WCSB supply to LNG export facilities on the Canadian west coast, 
through future extensions of the system or future connections to other pipelines serving that area.

Canadian Mainline: This pipeline supplies markets in Ontario, Québec, the Canadian Maritimes as well as the Midwest and 
Northeast U.S. from the WCSB and, through interconnects, from the Appalachian basin. 

U.S. Natural Gas Pipelines

Columbia Gas: This is our natural gas transportation system for the Appalachian basin, which contains the Marcellus and Utica 
shale plays, two of the largest natural gas shale plays in North America. Similar to our footprint in the WCSB, our Columbia Gas 
assets are well positioned to connect growing supply to markets in this area. This system also interconnects with other pipelines 
that provide access to key markets in the U.S. Northeast, the Midwest, the Atlantic coast and south to the Gulf of Mexico and its 
growing demand for natural gas to serve LNG exports. 

ANR: This pipeline system connects supply basins and markets throughout the U.S. Midwest, and south to the Gulf of Mexico. 
This includes connecting supply in Texas, Oklahoma, the Appalachian basin and the Gulf of Mexico to markets in Wisconsin, 
Michigan, Illinois and Ohio. In addition, ANR has bidirectional capability on its Southeast Mainline and delivers gas produced from 
the Appalachian basin to customers throughout the U.S. Gulf Coast region.

Columbia Gulf: This pipeline system transports growing Appalachian basin supplies to various U.S. Gulf Coast markets and LNG 
export terminals from its interconnections with Columbia Gas and other pipelines. 

TC PipeLines, LP: We own a 25.5 per cent interest in TC PipeLines, LP, which has ownership interests in eight wholly-owned or 
partially-owned natural gas pipelines serving major markets in the U.S. Refer to the Corporate - Significant events section for 
additional information regarding the proposed acquisition of all outstanding common units not beneficially owned by TC Energy 
or our affiliates in exchange for TC Energy common shares.

Mexico Natural Gas Pipelines

Sur de Texas: This offshore pipeline transports 20 per cent of Mexico's natural gas requirements from Texas to power and 
industrial markets in the eastern and central regions of the country. We own a 60 per cent interest in and are the operator of this 
pipeline. 

Northwest System: The Topolobampo and Mazatlán pipelines make up our Mexico northwest system. The system runs through 
the states of Chihuahua and Sinaloa, supplying power plants and industrial facilities, bringing natural gas to a region of the 
country that previously did not have access to it.

TC Energy Management's discussion and analysis 2020   |  31

TGNH System: This system is located in the central region of Mexico and is comprised of the Tamazunchale pipeline and the   
Tula and Villa de Reyes pipelines currently under construction. This system supplies or will supply several power plants and 
industrial facilities in Veracruz, San Luis Potosí, Querétaro and Hidalgo. It has interconnects with upstream pipelines that bring in 
supply from the Agua Dulce and Waha basins in Texas. 

Guadalajara: This bidirectional pipeline connects imported LNG supply near Manzanillo and continental gas supply near 
Guadalajara to power plants and industrial customers in the states of Colima and Jalisco.

Regulation of tolls and cost recovery
Our natural gas pipelines are generally regulated by the CER in Canada, FERC in the U.S. and CRE in Mexico. These entities 
regulate the construction, operation and requested abandonment of pipeline infrastructure.

Regulators in Canada, the U.S. and Mexico allow us to recover costs to operate the network by collecting tolls for services. These 
tolls generally include a return on our capital invested in the assets or rate base as well as recovery of the rate base over time 
through depreciation. Other costs generally recovered through tolls include OM&A, taxes and interest on debt. The regulators 
review our costs to ensure they are reasonable and prudently incurred and approve tolls that provide a reasonable opportunity to 
recover those costs.

Business environment and strategic priorities
The North American natural gas pipeline network has been developed to connect diverse supply regions to domestic markets 
and, increasingly, to meet demand from LNG export facilities. Use and growth of this infrastructure is affected by changes in the 
location and relative cost of natural gas supplies as well as changes in the location of markets and level of demand.

We have significant pipeline footprints that serve two of the most prolific supply regions of North America – the WCSB and the 
Appalachian basin. Our pipelines also source natural gas from other significant basins including the Rockies, Williston, 
Haynesville, Fayetteville and Anadarko basins as well as the Gulf of Mexico. We expect continued growth in North American 
natural gas production to meet demand within growing domestic markets, particularly in the electric generation and industrial 
sectors which benefit from a relatively low natural gas price. In addition, North American supply is expected to benefit from 
increased natural gas demand in Mexico and access to international markets via LNG exports. We expect North American natural 
gas demand, including LNG exports, of approximately 128 Bcf/d by 2025, reflecting an increase of approximately 17 Bcf/d from 
2020 levels. 

This expected increased demand for natural gas, coupled with the replacement of existing supply sources that have an 
approximate 25 per cent annual decline rate, implies that over 45 Bcf/d of new natural gas supply connections will be needed in 
the next two years, providing investment opportunities for pipeline infrastructure companies to build new facilities or increase 
utilization of the existing footprint. 

Changing demand
The growing supply of natural gas has resulted in relatively low natural gas prices in North America which has supported 
increased demand, particularly in the following areas:
• natural gas-fired electric-power generation
• petrochemical and industrial facilities
• Alberta oil sands
• increased demand in Mexico to fuel power generation and other industrial facilities.

Natural gas producers continue to progress opportunities to sell natural gas to global markets which involves connecting natural 
gas supplies to LNG export terminals, both operating and proposed, along the U.S. Gulf Coast; the west coast of Canada, the  
U.S. and Mexico; and the east coast of Canada. The demand created by the addition of these new markets provides opportunities 
for us to build new pipeline infrastructure and to increase throughput on our existing pipelines.

32  |   TC Energy Management's discussion and analysis 2020

Commodity prices
In general, the profitability of our natural gas pipelines business is not directly tied to commodity prices given we are a 
transporter of the commodity and the fixed transportation costs are not tied to the price of natural gas. However, the cyclical 
supply and demand nature of commodities and related pricing can have an indirect impact on our business where producers may 
choose to accelerate or delay development of gas reserves or, similarly on the demand side, projects requiring natural gas may 
be accelerated or delayed depending on market or price conditions. For example, lower natural gas prices have allowed        
North American natural gas to gain market share over coal in serving power generation markets and to compete globally through 
LNG exports. 

More competition
Changes in supply and demand levels and locations have resulted in increased competition to provide transportation services 
throughout North America. Our well-distributed footprint of natural gas pipelines, particularly in the liquids-rich and low-cost 
WCSB and the Appalachian basin, both of which are connected to North American demand centres, has placed us in a strong 
competitive position. Incumbent pipelines benefit from the connectivity and economies of scale afforded by the base 
infrastructure as well as existing right-of-way and operational synergies given the increasing challenges of siting and permitting 
new pipeline construction and expansions. We have and will continue to offer competitive services to capture growing supply 
and North American demand that now includes access to global markets through LNG exports.

Strategic priorities
Our pipelines deliver the natural gas that millions of individuals and businesses across North America rely on for their energy 
needs. We are focused on capturing opportunities resulting from growing natural gas supply and connecting new markets while 
satisfying increasing demand for natural gas within existing markets. We are also focused on adapting our existing assets to the 
changing natural gas flow dynamics. 

In 2021, some of our key focus areas will be the continued execution of our existing capital program that includes further 
investment in the NGTL System, continued construction of Coastal GasLink as well as the completion and initiation of new 
pipeline projects in the U.S. and Mexico. We will also continue to pursue the next wave of growth opportunities. Our goal is to 
place all of our projects in service on time and on budget while ensuring the safety of the environment and general public 
impacted by the construction and operation of these facilities. 

Our U.S. and Mexico natural gas marketing entities will complement pipeline operations and generate non-regulated revenues 
by managing the procurement of natural gas supply and pipeline transportation capacity for natural gas customers within our 
pipeline corridors.

Canadian Natural Gas Pipelines

UNDERSTANDING OUR CANADIAN NATURAL GAS PIPELINES SEGMENT
The Canadian natural gas pipeline business is subject to regulation by various federal and provincial governmental agencies. The 
CER has jurisdiction over our regulated Canadian natural gas interprovincial pipeline systems, while provincial regulators have 
jurisdiction over pipeline systems operating entirely within a single province. All of our major Canadian natural gas pipeline 
assets are regulated by the CER with the exception of Coastal GasLink, which is currently under construction. 

For the interprovincial natural gas pipelines it regulates, the CER approves tolls and services that are in the public interest and 
provide a reasonable opportunity for a pipeline to recover its costs to operate the pipeline. Included in the overall toll is a return 
on the investment we have made in the assets, referred to as the return on equity. Equity is generally 40 per cent of the deemed 
capital structure, with the remaining 60 per cent debt. Typically, tolls are based on the cost of providing service, including the 
cost of financing, divided by a forecast of throughput volumes. Any variance in either costs or the actual volumes transported 
can result in an over-collection or under-collection of revenues that is normally trued up the following year in the calculation of 
the tolls for that period. The return on equity, however, would continue to be earned at the rate approved by the CER. 

We and our shippers can also establish settlement arrangements, subject to approval by the CER, that may have elements that 
vary from the typical toll-setting process. Settlements can include longer terms and mechanisms such as incentive agreements 
that can have an impact on the actual return on equity achieved. Examples include fixing the OM&A component in determining 
revenue requirements, where variances are to the pipeline's account or shared between the pipeline and shippers. 

The NGTL System is operating under a five-year revenue requirement settlement for 2020-2024 that includes an incentive 
mechanism for certain operating costs. The Canadian Mainline was in the final year of a six-year fixed toll settlement that 
included an incentive arrangement, which ended on December 31, 2020. As of January 1, 2021, the Canadian Mainline will 
operate under a new six-year settlement which also includes an incentive to decrease costs and/or increase revenues.

SIGNIFICANT EVENTS

Coastal GasLink Pipeline Project
On May 22, 2020, we completed the sale of a 65 per cent equity interest in Coastal GasLink LP for net proceeds of $656 million 
before post-closing adjustments and recorded a pre-tax gain of $364 million ($402 million after tax). The after-tax gain includes 
the gain on sale, utilization of previously unrecognized tax loss benefits and the required remeasurement of our 35 per cent 
retained ownership to fair value including a derivative instrument used to hedge the interest rate risk on the project-level credit 
facilities. Under the terms of the equity purchase agreement, the net proceeds included reimbursement of a 65 per cent equity 
share of project costs incurred to May 22, 2020. As part of the transaction, we were contracted by Coastal GasLink LP to 
construct and operate the pipeline. Effective with closing, we commenced recognition of development fee revenue earned 
during the construction of the pipeline for management and financial services provided and began accounting for our remaining 
35 per cent investment using equity accounting.

In conjunction with the equity sale, Coastal GasLink LP entered into project-level credit facilities with a current total capacity of 
$6.8 billion which will fund the majority of the construction costs of Coastal GasLink. Immediately preceding the equity sale, 
Coastal GasLink LP drew down $1.6 billion on the facilities, of which approximately $1.5 billion was paid to TC Energy. Coastal 
GasLink LP has also entered into a subordinated demand revolving credit facility with TC Energy on commercial terms to provide 
additional short-term liquidity and funding flexibility to the project.

We continue to work with the 20 First Nations that have executed agreements with Coastal GasLink LP to provide them with an 
opportunity to invest in the project through an option to acquire a 10 per cent equity interest.

The introduction of partners, utilization of dedicated project-level credit facilities, recovery of cash payments through 
construction for carrying charges on costs incurred and remuneration for costs paid to close of the sale are expected to 
substantially satisfy our funding requirements through project completion.

Due to COVID-19, on December 29, 2020, the British Columbia Provincial Health Officer issued an order restricting the number of 
workers on site for industrial projects in the Northern Health Authority region of British Columbia. Industrial projects must submit 
restart plans to the Provincial Health Officer detailing steps to resume site work. Coastal GasLink LP is working with the provincial 
health authorities to safely resume construction activities in accordance with the objectives and timelines defined in the order.

38  |   TC Energy Management's discussion and analysis 2020

The project is working with LNG Canada on establishing a revised project plan for Coastal GasLink. We expect that project costs 
will increase significantly and the schedule will be delayed compared to the previously disclosed estimate due to scope increases, 
permit delays and the impacts from COVID-19, including the provincial health order, although Coastal GasLink will continue to 
mitigate these impacts to the extent possible. These incremental costs will be included in the final pipeline tolls, subject to 
certain conditions. We do not anticipate our future equity contributions will increase significantly following the conclusion of 
this process.

NGTL System
In the year ended December 31, 2020, the NGTL System placed approximately $3.4 billion of capacity projects in service.

NGTL System Expansion Programs
On February 19, 2020, the CER issued a report recommending that the GIC approve the 2021 NGTL System Expansion Program, 
which the GIC approved on October 19, 2020. The NGTL System subsequently progressed construction activities in accordance 
with the regulatory requirements resulting in compressor station field work beginning in December 2020 and pipeline 
construction activities in January 2021.

Once facilities are placed in service, the 2021 NGTL System Expansion Program is expected to provide 1.59 PJ/d (1.45 Bcf/d) of 
incremental system capacity underpinned by long-term receipt and delivery contracts, connecting incremental supply to 
growing intra-basin and export markets. In-service is expected to commence in late 2021 with remaining program components 
completed by April 2022.

In second quarter 2020, the NGTL System held a Capacity Optimization Open Season soliciting requests for the deferral or 
advancement of pending contracts to assist customers in optimizing their transportation service needs and align system 
expansions with customer growth requirements. Following analysis of the results of the open season, we concluded that all 
proposed system expansion projects continue to be required to meet aggregate system demand, although the in-service dates 
for some facilities have been delayed. This resulted in the deferral of a portion of planned capital program spending from 2020 
and 2021 to 2022 through 2024. The net impact of these deferrals, together with some expected increase in project costs on the 
2021 NGTL System Expansion Program, have been incorporated into the Secured projects table in this MD&A.

North Montney
The North Montney project consists of approximately 206 km (128 miles) of new pipeline along with three compressor units and 
13 meter stations. On January 31, 2020, the $1.1 billion Aitken Creek section of the North Montney project was placed into service 
with the final section of the project, Kahta South, in service on May 1, 2020. All compressor stations, pipeline sections and 11 of 
the 13 meter stations are complete and operational, with the remaining two meter stations expected to be in service in 2021.

NGTL System Rate Design
In March 2019, the NGTL System Rate Design and Services Application was filed with the NEB which addressed rate design, terms 
and conditions of service for the NGTL System and a tolling methodology for the North Montney Mainline. The CER issued a 
decision on March 25, 2020 approving all elements of the application as filed.

NGTL System Revenue Requirement Settlement
On August 17, 2020, the CER approved the NGTL System's 2020-2024 Revenue Requirement Settlement negotiated with its 
customers and other interested parties. The settlement, effective January 1, 2020, maintains the equity return at 10.1 per cent on 
40 per cent deemed common equity, provides the NGTL System with the opportunity to increase depreciation rates if tolls fall 
below projected levels and includes an incentive mechanism for certain operating costs where variances from projected amounts 
are shared between the NGTL System and its customers. It also includes a mechanism to review the settlement should tolls 
exceed a pre-determined level, without affecting the equity return. 

Canadian Mainline
During 2020, the Canadian Mainline placed approximately $0.2 billion of capacity projects in service.

On April 17, 2020, the CER approved a six-year unanimously supported negotiated settlement between the Canadian Mainline, 
its customers and other stakeholders. The settlement, effective January 1, 2021, sets a base equity return of 10.1 per cent on      
40 per cent deemed common equity and includes an incentive to either decrease costs and/or increase revenues on the pipeline 
with a beneficial sharing mechanism to both the shippers and us.

Includes results from Foothills, Ventures LP, Great Lakes Canada and our investment in TQM, Coastal GasLink development fee revenue as well as general and 
administrative and business development costs related to our Canadian Natural Gas Pipelines.

Canadian Natural Gas Pipelines segmented earnings increased by $542 million in 2020 compared to 2019 which included a      
pre-tax gain in 2020 of $364 million related to the sale of a 65 per cent equity interest in Coastal GasLink LP which has been 
excluded from our calculation of comparable EBIT and comparable earnings. Canadian Natural Gas Pipelines comparable EBIT and 
segmented earnings decreased by $135 million in 2019 compared to 2018.

Net income and comparable EBITDA for our rate-regulated Canadian natural gas pipelines are primarily affected by our approved 
ROE, our investment base, the level of deemed common equity and incentive earnings. Changes in depreciation, financial 
charges and income taxes also impact comparable EBITDA but do not have a significant impact on net income as they are almost 
entirely recovered in revenues on a flow-through basis.

Net income for the NGTL System increased by $81 million in 2020 compared to 2019 and $86 million in 2019 compared to 2018 
mainly due to a higher average investment base resulting from continued system expansions. On August 17, 2020, the CER 
approved the NGTL System's 2020-2024 Revenue Requirement Settlement Application. This settlement, which is effective from 
January 1, 2020 to December 31, 2024, includes an ROE of 10.1 per cent on 40 per cent deemed equity, provides the NGTL System 
the opportunity to increase depreciation rates if tolls fall below pre-determined levels and includes an incentive mechanism for 
certain operating costs where variances from projected amounts are shared between the NGTL System and its customers. It also 
includes a mechanism to review the settlement should tolls exceed a pre-determined level, without affecting the equity return. 
The NGTL System’s 2019 and 2018 results reflected the 2018-2019 Revenue Requirement Settlement that expired on       
December 31, 2019 which included an ROE of 10.1 per cent on 40 per cent deemed common equity, a mechanism for sharing 
variances above and below a fixed annual OM&A amount and flow-through treatment of all other costs.

The Canadian Mainline’s net income in 2020 decreased by $13 million compared to 2019 mainly as a result of lower incentive 
earnings. Net income in 2019 decreased by $9 million compared to 2018 mainly as a result of lower incentive earnings and a 
lower average investment base, partially offset by lower carrying charges to shippers on the 2019 net revenue surplus.

In 2020, the Canadian Mainline was in the final year of a six-year fixed-toll settlement under the terms of the 2015-2030 Tolls 
Application approved in 2014 (the NEB 2014 Decision). The terms of the settlement included an ROE of 10.1 per cent on deemed 
common equity of 40 per cent, an incentive mechanism with both upside and downside risk and a $20 million after-tax annual 
TC Energy contribution to reduce the revenue requirement. Toll stabilization was achieved through the use of deferral accounts, 
namely the bridging amortization account and the long-term adjustment account (LTAA), to capture the surplus or shortfall 
between system revenues and cost of service for each year over the 2015-2020 six-year fixed-toll term of the NEB 2014 Decision. 

The NEB 2014 Decision also directed TC Energy to file an application to review tolls for the 2018-2020 period. In December 2018, 
the NEB 2018 Decision was received which included an accelerated amortization of the December 31, 2017 LTAA balance and an 
increase to the composite depreciation rate from 3.2 per cent to 3.9 per cent which was reflected in 2019 and 2020 tolls. 

Comparable EBITDA
Comparable EBITDA for Canadian Natural Gas Pipelines was $292 million higher in 2020 compared to 2019 primarily due to the 
net effect of:
• increased rate-base earnings and flow-through depreciation due to additional facilities placed in service as well as higher flow-

through financial charges on the NGTL System

• lower flow-through income taxes and reduced incentive earnings on the Canadian Mainline and the NGTL System 
• Coastal GasLink development fee revenue recognized in 2020. Refer to the Canadian Natural Gas Pipelines - Significant events 

section for additional information.

Comparable EBITDA for Canadian Natural Gas Pipelines in 2019 was $105 million lower than 2018 largely resulting from the net 
effect of: 
• lower flow-through income taxes on the NGTL System and on the Canadian Mainline from the impact of the NEB 2018 Decision 
to accelerate amortization of the LTAA as well as accelerated tax depreciation enacted by the Canadian Federal Government in 
June 2019 to allow businesses in Canada to deduct the cost of their investments more quickly for income tax purposes. Due to 
the flow-through treatment of income taxes on our Canadian rate-regulated pipelines, such reductions to income tax reduced 
our comparable EBITDA despite having no significant impact on net income

• increased rate-base earnings and depreciation on the NGTL System due to additional facilities that were placed in service, 

which were partially offset by the impact of a lower rate base in the Canadian Mainline.

Depreciation and amortization
Depreciation and amortization was $114 million higher in 2020 compared to 2019 and $30 million higher in 2019 compared to 
2018 mainly due to additional NGTL System facilities placed in service in 2020 and 2019.

OUTLOOK

Comparable earnings
Net income for Canadian rate-regulated pipelines is affected by changes in investment base, ROE and deemed capital structure 
as well as by the terms of toll settlements approved by the CER. Under the current regulatory model, earnings from Canadian 
rate-regulated natural gas pipelines are not materially affected by short-term fluctuations in the commodity price of natural gas, 
changes in throughput volumes or changes in contracted capacity levels.

Canadian Natural Gas Pipelines earnings in 2021 are expected to be higher than 2020 mainly due to continued growth in the 
NGTL System as we extend and expand the supply facilities in the North Montney region, enhance delivery facilities in 
northeastern Alberta and provide incremental service at our major border delivery locations in response to requests for firm 
service on the system. In addition, we expect a higher contribution from the Canadian Mainline in 2021 due to increased 
incentive earnings.

Other Canadian pipelines earnings are expected to be higher in 2021 due to increased Coastal GasLink development fee revenue 
reflecting the planned increase in project activity in 2021, subject to the extent of the impact of COVID-19 delays and 
restrictions.

Capital spending
We spent a total of $3.6 billion in 2020 in our Canadian natural gas pipelines business, of which $0.9 billion related to our 
investment in Coastal GasLink prior to the sale of an equity interest in Coastal GasLink LP as well as subsequent equity 
contributions to the project. We expect to spend approximately $3.4 billion in 2021, primarily on NGTL System expansion 
projects, Canadian Mainline capacity projects and maintenance capital expenditures, all of which are immediately reflected in 
investment base and related earnings.

U.S. Natural Gas Pipelines

UNDERSTANDING OUR U.S. NATURAL GAS PIPELINES SEGMENT
The U.S. interstate natural gas pipeline business is subject to regulation by various federal, state and local governmental 
agencies. FERC, however, has comprehensive jurisdiction over our U.S. natural gas business. FERC approves maximum 
transportation rates that are cost-based and are designed to recover the pipeline's investment, operating expenses and a 
reasonable return for our investors. In the U.S., we have the ability to contract for negotiated or discounted rates with shippers. 

FERC does not require U.S. interstate pipelines to calculate rates annually, nor do they generally allow for the collection or refund 
of the variance between actual and expected revenues and costs into future years. This difference in U.S. regulation from the 
Canadian regulatory environment puts our U.S. pipelines at risk for the difference in expected and actual costs and revenues 
between rate cases. If revenues no longer provide a reasonable opportunity to recover our costs, we can file with FERC for a new 
determination of rates, subject to any moratorium in effect. Similarly, FERC or our shippers may institute proceedings to lower 
rates if they consider the return on capital invested to be unjust or unreasonable. 

Similar to Canada, we can also establish settlement arrangements with our U.S. shippers that are ultimately subject to approval 
by FERC. Rate case moratoriums for a period of time before either we or the shippers can file for a rate review are common for a 
settlement in that they provide some certainty for shippers in terms of rates, eliminate the costs associated with frequent rate 
proceedings for all parties and can provide an incentive for pipelines to lower costs. 

PHMSA Compliance Regulation
Most of our U.S. natural gas pipeline systems are subject to federal pipeline safety statutes and regulations enacted and 
administered by the U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration (PHMSA). PHMSA 
has disseminated regulations governing, among other things, maximum operating pressures, pipeline patrols and leak surveys, 
public awareness, operation and maintenance procedures, operator qualification, minimum depth requirements and emergency 
procedures. Additionally, PHMSA has put into place regulations requiring pipeline operators to develop and implement integrity 
management programs for certain natural gas pipelines that, in the event of a pipeline leak or rupture, could affect                
high-consequence areas, which are areas where a release could have the most significant adverse consequences, including   
high-population areas.

During 2016, PHMSA proposed new rules to revise the U.S. Federal Pipeline Safety Regulations and issued a Notice of Public 
Rulemaking for natural gas transmission and gathering lines that would, if adopted, impose more stringent inspection, reporting, 
and integrity management requirements on operators. However, PHMSA has since decided to split its 2016 proposed rule, which 
has become known as the Gas Mega Rule, into three separate rulemakings focusing on (1) maximum allowable operating 
pressure and integrity assessments on non-high consequence areas known as moderate consequence areas; (2) repair criteria, 
inspections and corrosion control; and (3) gathering lines. The first of these three rulemakings, for onshore natural gas 
transmission pipelines, was published as a final rule in October 2019. We continue to assess the operational and financial impact 
related to this final rule over its 15-year implementation window that began July 1, 2020 and seek to optimize recovery of those 
costs. The remaining rulemakings comprising the Gas Mega Rule are expected to be issued in 2021.

In addition to the rulemakings noted above, new pipeline safety legislation (Pipes Act of 2020) was signed into law on  
December 27, 2020 that reauthorized PHMSA pipeline safety programs which expired under the 2016 Pipeline Safety Act at the 
end of September 2019. We are in the process of assessing impacts associated with this new legislation.

SIGNIFICANT EVENTS

Wisconsin Access
On October 28, 2020, we approved the Wisconsin Access Project that will replace, upgrade and modernize certain facilities while 
reducing emissions along portions of the ANR pipeline system. The enhanced facilities will improve reliability of the ANR pipeline 
system and also allow for additional contracted transportation services of approximately 77 TJ/d (72 MMcf/d) to be provided to 
utilities serving the Midwestern U.S. under long-term contracts. The anticipated in-service date of the combined project is in the 
second half of 2022 with an estimated cost of US$0.2 billion.

Elwood Power Project/ANR Horsepower Replacement
On July 29, 2020, we approved the Elwood Power Project/ANR Horsepower Replacement that will replace, upgrade and 
modernize certain facilities while reducing emissions along a highly utilized section of the ANR pipeline system. The enhanced 
facilities will improve reliability of the ANR pipeline system and also allow for additional contracted transportation services of 
approximately 132 TJ/d (123 MMcf/d) to be provided to an existing power plant near Joliet, Illinois. The anticipated in-service 
date of the combined project is in the second half of 2022 with an estimated cost of US$0.4 billion.

Alberta XPress
On February 12, 2020, we approved the Alberta XPress project, an expansion project on the ANR pipeline system that utilizes 
existing capacity on the Great Lakes and Canadian Mainline systems to connect growing supply from the WCSB to U.S. Gulf Coast 
LNG export markets. The project has been modified to reflect revised shipper commitments. The anticipated in-service date is in 
the second half of 2022 with an estimated project cost of US$0.2 billion.

BXP
BXP, a Columbia Gas project representing an upsizing of existing pipeline replacement, in conjunction with our modernization 
program, was partially placed into service in October 2020 with full in-service commencing on January 1, 2021.

Columbia Gas Section 4 Rate Case
Columbia Gas filed a Section 4 Rate Case with FERC on July 31, 2020 requesting an increase to Columbia Gas' maximum 
transportation rates effective February 1, 2021, subject to refund. The rate case is progressing as expected as we continue to 
pursue a collaborative process to find a mutually beneficial outcome with our customers through settlement negotiations.

Acquisition of common units of TC PipeLines, LP
On December 15, 2020, we announced that we have entered into a definitive agreement and plan of merger to acquire all the 
outstanding common units of TC PipeLines, LP not beneficially owned by TC Energy or our affiliates in exchange for TC Energy 
common shares. Refer to the Corporate - Significant events section for additional information.

Results reflect our earnings from TC PipeLines, LP's ownership interests in eight natural gas pipelines as well as general and administrative costs related to           
TC PipeLines, LP. 
In prior years, TC PipeLines, LP periodically conducted ATM issuances which decreased our ownership in TC PipeLines, LP. Effective March 2018, this program 
ceased to be utilized. Our ownership interest in TC PipeLines, LP was 25.5 per cent as at December 31, 2020, 2019 and 2018.
Reflects our 53.55 per cent direct interest in Great Lakes. The remaining 46.45 per cent is held by TC PipeLines, LP.
Reflects earnings from our effective ownership in Crossroads, Millennium and Hardy Storage and certain Columbia Midstream assets until sold in August 2019, as 
well as general and administrative and business development costs related to U.S. natural gas pipelines.
Reflects earnings attributable to portions of TC PipeLines, LP, that we do not own.
These amounts were recorded in TC PipeLines, LP. The pre-tax impact to us is 25.5 per cent of these amounts net of non-controlling interests.

U.S. Natural Gas Pipelines segmented earnings in 2020 increased by $90 million compared to 2019 and increased by $1.0 billion in 
2019 compared to 2018 and included the following specific items which have been excluded from our calculation of comparable 
EBIT and comparable earnings:
• a pre-tax gain of $21 million related to the sale of certain Columbia Midstream assets in August 2019 
• a $722 million pre-tax non-cash asset impairment charge in 2018 related to Bison
• a $79 million pre-tax non-cash goodwill impairment charge in 2018 related to Tuscarora 
• $130 million of pre-tax customer termination payments in 2018 that were recorded in Revenues with respect to two of Bison’s 

transportation contracts.

A stronger U.S. dollar in 2020 had a positive impact on the Canadian dollar equivalent segmented earnings from our                  
U.S. operations compared to the same period in 2019 with a similar impact on 2019 compared to 2018.

Each of the specific items in 2018 noted above are prior to recognition of the 74.5 per cent non-controlling interests in                   
TC PipeLines, LP.

Earnings from our U.S. Natural Gas Pipelines operations are generally affected by contracted volume levels, volumes delivered 
and the rates charged as well as by the cost of providing services. Columbia and ANR results are also affected by the contracting 
and pricing of their storage capacity and incidental commodity sales. Pipeline and storage volumes and revenues are generally 
higher in the winter months because of the seasonal nature of the business.

Comparable EBITDA for U.S. Natural Gas Pipelines was US$91 million higher in 2020 than 2019 primarily due to the net effect of:
• incremental earnings from Columbia Gas and Columbia Gulf growth projects placed in service as well as lower operating costs 

in 2020

• increased earnings from ANR due to the sale of natural gas from certain gas storage facilities
• decreased earnings as a result of the sale of certain Columbia Midstream assets in August 2019.

Comparable EBITDA for U.S. Natural Gas Pipelines was US$282 million higher in 2019 than 2018 primarily due to the net effect of:
• incremental earnings from Columbia Gas and Columbia Gulf growth projects placed in service
• decreased earnings from Bison (wholly owned by TC PipeLines, LP) following 2018 customer agreements to settle their future 

contracted revenues and terminate their contracts

• decreased earnings as a result of the sale of certain Columbia Midstream assets in August 2019.

Depreciation and amortization
Depreciation and amortization was US$29 million higher in 2020 compared to 2019 and was US$57 million higher in 2019 
compared to 2018 mainly due to new projects placed in service. The 2019 amount also reflects lower depreciation as a result of 
the Bison asset impairment in 2018.

OUTLOOK

Comparable earnings
Our U.S. natural gas pipelines are largely backed by long-term take-or-pay contracts that are expected to deliver stable and 
consistent financial performance. Our ability to retain customers and recontract or sell capacity at favourable rates is influenced 
by prevailing market conditions and competitive factors, including alternatives available to end-use customers in the form of 
competing natural gas pipelines and supply sources as well as broader conditions that impact demand from certain customers or 
market segments. Earnings are also affected by the level of operational and other costs, which can be impacted by safety, 
environmental and other regulators' decisions, as well as customer credit risk.

U.S. Natural Gas Pipelines earnings are expected to be slightly higher in 2021 than in 2020 due to an increase in transportation 
rates on Columbia Gas that is dependent on the outcome of the Section 4 Rate Case filed with FERC. In addition, revenues are 
expected to increase following the completion of expansion projects on the Columbia Gas and ANR systems in 2021 which will 
provide our customers with greater access to new sources of supply while extending their market reach. Our pipeline systems 
continue to see historically strong demand for service and we anticipate our assets will maintain high utilization levels as were 
experienced in 2020. These expected positive results will be partially offset by an anticipated increase in property taxes from 
capital projects placed in service.

While certain of our counterparties may have varying risks to their operations from the outcomes related to COVID-19, we do not 
expect a significant impact to our business.

Capital spending
We spent a total of US$2.0 billion in 2020 on our U.S. natural gas pipelines and expect to spend approximately US$2.2 billion in 
2021 primarily on ANR, Columbia Gulf and GTN expansion projects as well as Columbia Gas and ANR maintenance capital, which 
is expected to be reflected in future tolls.

Mexico Natural Gas Pipelines

UNDERSTANDING OUR MEXICO NATURAL GAS PIPELINES SEGMENT
For over a decade, Mexico has been undergoing a significant transition from fuel oil and diesel as its primary energy sources for 
electric generation to using natural gas. As a result, new natural gas pipeline infrastructure has been and continues to be 
required to meet the growing demand for natural gas. Large natural gas pipelines in Mexico have been developed primarily 
through a competitive bid process. The CFE, Mexico's state-owned electric utility, is the counterparty on all of our existing 
pipelines under long-term contracts, which are predominately denominated in U.S. dollars. These fixed-rate contracts are 
generally designed to recover the cost of service and provide a return on and of invested capital. As the pipeline developer and 
operator, we are at risk for operating and construction costs and in-service delay penalties, excluding force majeure events. Our 
Mexico pipelines have approved tariffs, services and related rates for other potential users.

SIGNIFICANT EVENTS

Tula and Villa de Reyes
The CFE initiated arbitration in June 2019 for the Tula and Villa de Reyes projects, disputing fixed capacity payments due to force 
majeure events. Arbitration proceedings are suspended while management advances settlement discussions with the CFE.

Villa de Reyes project construction is ongoing. Phased in-service has been delayed due to COVID-19 contingency measures which 
have impeded our ability to obtain work authorizations as a result of administrative closures. Subject to the timely re-opening of 
government agencies, we expect to complete construction of Villa de Reyes in 2021. 

Guadalajara
A project to allow bidirectional flows was completed in December 2020 and the TSA with the CFE was renegotiated. The 
bidirectional flow allows access to either LNG imports from the Manzanillo terminus or access to continental natural gas at the 
Guadalajara terminus for delivery to regional markets.

FINANCIAL RESULTS
The following is a reconciliation of comparable EBITDA and comparable EBIT (our non-GAAP measures) to segmented earnings 
(the most directly comparable GAAP measure). Refer to page 11 for more information on non-GAAP measures we use.

Represents equity income from our 60 per cent interest and fees earned from the construction and operation of the pipeline.

Mexico Natural Gas Pipelines segmented earnings in 2020 increased by $179 million compared to 2019 and decreased by             
$20 million in 2019 compared to 2018. A stronger U.S. dollar in 2020 had a positive impact on the Canadian dollar equivalent 
segmented earnings from our Mexico operations compared to the same period in 2019, with a similar impact on 2019 compared 
to 2018.

Comparable EBITDA for Mexico Natural Gas Pipelines increased by US$127 million in 2020 compared to 2019 mainly due to higher 
earnings from our investment in the Sur de Texas pipeline resulting from:
• increased Sur de Texas equity income from the commencement of transportation services in September 2019
• revenues of US$55 million recognized in 2020 from fees associated with the successful completion of the Sur de Texas pipeline 

as well as ongoing fees earned from operating the pipeline.

Prior to in-service, Sur de Texas equity income primarily reflected AFUDC during construction, net of our proportionate share of 
interest expense on peso-denominated inter-affiliate loans. These inter-affiliate loans remain in place and our share of related 
interest expense in Sur de Texas continues to be fully offset by corresponding interest income recorded in Interest income and 
other in the Corporate segment.

Comparable EBITDA for Mexico Natural Gas Pipelines decreased by US$11 million in 2019 compared to 2018 primarily from the net 
effect of:
• lower revenues from wholly-owned operations primarily as a result of changes in timing of revenue recognition in 2018
• higher equity earnings from our investment in the Sur de Texas pipeline following its September 2019 in-service. Prior to this, 
Sur de Texas equity income reflected AFUDC, net of our proportionate share of interest expense on aforementioned           
inter-affiliate loans which is fully offset in Interest income and other. 

Depreciation and amortization
Depreciation and amortization in 2020 was consistent with the same period in 2019. Depreciation and amortization in 2019 
increased by US$12 million compared with the same period in 2018 reflecting new assets being placed in service and other 
adjustments.

OUTLOOK

Comparable earnings
Mexico Natural Gas Pipelines earnings reflect long-term, stable, principally U.S. dollar-denominated transportation contracts 
that are affected by the cost of providing service and include our share of equity income from our 60 per cent interest in the    
Sur de Texas pipeline.

Due to the long-term nature of the underlying transportation contracts, earnings are generally consistent year-over-year except 
when new assets are placed into service. Earnings for 2021 are expected to be lower than 2020 due to the fees recognized in 
2020 associated with the completion of Sur de Texas, partially offset by the expected in-service of Villa de Reyes in 2021.

Capital spending
We spent approximately US$0.1 billion in 2020 primarily related to the construction of the Villa de Reyes pipeline. Capital 
spending in 2021 to complete construction of Villa de Reyes is expected to be US$0.1 billion.

NATURAL GAS PIPELINES – BUSINESS RISKS 
The following are risks specific to our natural gas pipelines business. Refer to page 88 for information about general risks related 
to TC Energy as a whole, including other operational, safety and financial risks as well as our approach to risk management.

Production levels within supply basins
The NGTL System and our pipelines downstream depend largely on supply from the WCSB. Our Columbia Gas system and its 
connecting pipelines largely depend on Appalachian supply. We continue to monitor any changes in our customers' natural gas 
production plans and how these may impact our existing assets and new project schedules. There is competition amongst 
pipelines to connect to major basins. An overall decrease in production and/or increased competition for supply could reduce 
throughput on our connected pipelines that, in turn, could negatively impact overall revenues generated. The WCSB and 
Appalachian basins are two of the most prolific and cost-competitive basins in North America and have considerable natural gas 
reserves. However, the amount actually produced depends on many variables including the price of natural gas and natural gas 
liquids, basin-on-basin competition, pipeline and gas-processing tolls, demand within the basin, changes in regulations, and the 
overall value of the reserves, including liquids content. 

Market access 
We compete for market share with other natural gas pipelines. New supply basins being developed closer to markets we have 
historically served may reduce the throughput and/or distance of haul on our existing pipelines and impact revenues. New 
markets, including those created by LNG export facilities developed to access global natural gas demand, can lead to increased 
revenues through higher utilization of existing facilities and/or demand for new infrastructure. The long-term competitiveness of 
our pipeline systems and the avoidance of bypass pipelines will depend on our ability to adapt to changing flow patterns by 
offering competitive transportation services to the market.

Competition for greenfield expansion
We face competition from other pipeline companies seeking to invest in greenfield natural gas pipeline development 
opportunities. This competition could result in fewer projects being available that meet our investment hurdles or projects that 
proceed with lower overall financial returns.

Demand for pipeline capacity
Demand for pipeline capacity is ultimately the key driver that enables pipeline transportation services to be sold and is impacted 
by supply and market competition, variations in economic activity, weather variability, natural gas pipeline and storage 
competition, energy conservation and demand for and prices of alternative sources of energy. Renewal of expiring contracts and 
the opportunity to charge a competitive toll depends on the overall demand for transportation service. A decrease in the level of 
demand for our pipeline transportation services could adversely impact revenues, although overall utilization of our pipeline 
capacity continues to grow and warrant further investment and expansion.

Commodity prices
The cyclical supply and demand nature of commodities and related pricing can have a secondary impact on our business where 
our shippers may choose to accelerate or delay certain projects. This can impact the timing for the demand of transportation 
services and/or new natural gas pipeline infrastructure. As well, sustained low natural gas prices could impact our shippers' 
financial condition and their ability to meet their transportation service cost obligations.

Regulatory risk
Decisions and evolving policies by regulators and other government authorities, including changes in regulation, can have an 
impact on the approval, timing, construction, operation and financial performance of our natural gas pipelines. There is a risk 
that decisions are delayed or are not favourable and therefore could adversely impact construction costs, in-service dates, 
anticipated revenues, and the opportunity to further invest in our systems. There is also risk of a regulator disallowing a portion 
of our prudently incurred costs, now or at some point in the future. 

The regulatory approval process for larger infrastructure projects, including the time it takes to receive a decision, could be 
delayed or lead to an unfavourable decision due to influence from the evolving role of activists and other stakeholders and their 
impact on public opinion and government policy related to natural gas pipeline infrastructure development. In addition, a 
number of these matters may also involve legal disputes that are prosecuted in a court of law, thereby further impacting project 
costs and creating delays. 

Increased scrutiny of construction and operations processes by the regulator, courts or other enforcing agencies has the 
potential to delay construction, increase operating costs or require additional capital investment. There is a risk of an adverse 
impact to income if these costs are not fully recoverable and/or reduce the competitiveness of tolls charged to customers. 

We continuously manage these risks by monitoring regulatory developments and decisions to determine the possible impact on 
our natural gas pipelines business and the development of rate, facility and tariff applications that account for and mitigate the 
risks where possible.

Governmental risk
Shifts in government policy by existing bodies or following changes in government can impact our ability to grow our business. 
Restrictions on carbon fuel use, cross-border economic activity, and development of new infrastructure can impact our 
opportunities for continued growth. We are committed to working with all levels of government to ensure our business benefits 
and risks are understood, and mitigation strategies are implemented. 

Construction and operations
Constructing and operating our pipelines to ensure transportation services are provided safely and reliably is essential to the 
success of our business. Interruptions in our pipeline operations impacting throughput capacity may result in reduced revenues 
and can affect corporate reputation as well as customer and public confidence in our operations. We manage this by investing in 
a highly skilled workforce, hiring third-party inspectors during construction, operating prudently, monitoring our pipeline 
systems continuously, using risk-based preventive maintenance programs and making effective capital investments. We use 
pipeline inspection equipment to regularly check the integrity of our pipelines, and repair or replace sections when necessary. 
We also calibrate meters regularly to ensure accuracy and employ robust reliability and integrity programs to maintain 
compression equipment and ensure safe and reliable operations.

Liquids Pipelines

Our existing liquids pipelines infrastructure connects Alberta crude oil supplies to U.S. refining markets in Illinois, Oklahoma and 
the U.S. Gulf Coast as well as U.S. crude oil supplies from the key market hub at Cushing, Oklahoma to the U.S. Gulf Coast. We 
also provide intra-Alberta liquids transportation.

Our liquids pipelines business includes:
• wholly-owned liquids pipelines – approximately 4,400 km (2,700 miles)
• wholly-owned operational and term storage – approximately 7 million barrels
• partially-owned liquids pipelines – over 500 km (300 miles).

Strategy
Optimizing the value of our existing Liquids Pipelines assets by expanding and leveraging our existing infrastructure is a top 
priority. We are also pursuing emerging growth opportunities to add incremental value to our business. 

Our key areas of focus include:
• accessing and delivering growing North American liquids supply to key markets by expanding our crude oil pipelines 

infrastructure to deliver directly from supply regions seamlessly along a contiguous path to market

• maximizing the value from our current operating assets and securing organic growth around these assets
• positioning our business development activities to identify and capture attractive organic growth and acquisition 

opportunities consistent with our risk preferences

• expand transportation service offerings to other areas of the liquids value chain including ancillary services such as short-term 

and long-term storage of liquids, which complement our pipeline transportation infrastructure.

Recent highlights
• U.S. President Biden revoked the existing Presidential Permit for the Keystone XL pipeline on January 20, 2021. As a result, we 

have suspended the advancement of the project and are assessing the implications and options available to us

• During 2020 and 2021, we achieved the following milestones towards advancing the Keystone XL pipeline:

◦ announced that we would proceed with construction of Keystone XL which commenced in April 2020 in both the U.S. and 

Canada 

◦ completed the U.S./Canada border crossing on the Keystone XL pipeline in June 2020
◦ executed a Project Labor Agreement with four pipeline trade unions (Operating Engineers, Laborers, Teamsters and United 

Association) to utilize 100 per cent unionized labor in the construction of the Keystone XL pipeline

◦ announced that the Keystone XL pipeline would be operated with net-zero emissions once placed into service and would 

utilize 100 per cent green energy by 2030 to power the operating pump stations

◦ entered into an agreement whereby the Government of Alberta invested approximately US$0.8 billion in equity in    

Keystone XL as at December 31, 2020

◦ executed a US$4.1 billion credit facility, guaranteed by the Government of Alberta and non-recourse to us, to partially 

finance the construction of Keystone XL

◦ executed definitive agreements with Natural Law Energy, a consortium of five Canadian First Nations, for a potential 

investment of up to $1.0 billion equity investment in Keystone XL and future liquids projects.

UNDERSTANDING OUR LIQUIDS PIPELINES BUSINESS
Our Liquids Pipelines segment consists of crude oil and liquids/petroleum products pipelines, complemented by a liquids 
marketing business. We efficiently transport crude oil from major supply sources to markets where crude oil can be refined into 
various petroleum products, transport diluent and diesel products within Alberta, and offer ancillary services such as short- and 
long-term storage of liquids at key terminal locations to optimize the value of our pipeline assets. 

We provide pipeline transportation capacity to shippers predominantly supported by long-term contracts with fixed monthly 
payments that are not linked to actual throughput volumes or to the price of the commodity, generating stable earnings over 
the contract term. The terms of service and fixed monthly payments are determined by contracts negotiated with shippers 
which provide for the recovery of costs we incur to construct, operate and maintain the system. Uncontracted pipeline capacity 
is offered to the market to secure additional volumes on a monthly spot basis which provides opportunities to generate 
incremental earnings. Term storage of liquids at terminals is offered to our customers in return for fixed fee payments which are 
not linked to actual storage volumes or to the price of the commodity.

The Keystone Pipeline System, our largest liquids pipeline asset, transports approximately 20 per cent of western Canadian crude 
oil exports to key refining markets in the U.S. Midwest and the U.S. Gulf Coast. It also provides significant capacity between 
Cushing, Oklahoma and the U.S. Gulf Coast market, primarily transporting U.S. crude oil. Three intra-Alberta liquids pipelines – 
Grand Rapids, Northern Courier and White Spruce – provide crude oil, diluent and diesel transportation for producers in northern 
Alberta.

Our liquids marketing business provides customers with a variety of crude oil marketing services including transportation, 
storage and crude oil management, largely through the purchase and sale of physical crude oil. This business contracts for 
capacity on our pipelines as well as third-party owned pipelines and tank terminals.

Business environment
Global crude oil and liquids demand was significantly impacted by the COVID-19 pandemic as containment measures imposed by 
most countries around the world temporarily reduced transportation, commercial and non-essential activities. Demand is 
expected to gradually recover to pre-COVID-19 levels by 2022. 

Global crude oil and liquids demand is projected to increase after this near-term recovery from 92 million Bbl/d in 2020 to          
113 million Bbl/d in 2035, driven generally by the transportation and industrial sectors which account for 79 per cent of total 
crude oil and liquids demand. In addition to meeting this anticipated demand growth of approximately 21 million Bbl/d, a 
significant amount of crude oil production capacity is required to offset global conventional decline rates expected to reach 
approximately 16 million Bbl/d annually by 2035. To meet this demand requirement, a strong crude oil price environment is 
needed to support continuing investment in the energy sector. Global supply of crude oil necessary to meet this demand is 
expected to be sourced from countries with significant crude oil reserves, mainly in North America and the Middle East. 

Crude oil prices were severely impacted in 2020 by the COVID-19 pandemic and competition for market share by OPEC+ 
producers. However, a recovery will be supported by crude oil supply management efforts, primarily by OPEC+, and global 
demand growth that provides sufficient support for ongoing investments in new supply sources.

Supply outlook

Canada
Canada has the world’s third largest crude oil reserves with approximately 162 billion barrels of economically and technically 
recoverable conventional and oil sands reserves, primarily in Alberta. Total 2020 WCSB crude oil production was approximately   
4 million Bbl/d and is expected to increase to approximately 5 million Bbl/d by 2035, subject to the resolution of current           
ex-Alberta pipeline capacity constraints. Oil sands production comprises the majority of western Canadian crude oil supply at 
approximately 3 million Bbl/d and is a favourable supply source given its decades-long reserve life, steady production and rapidly 
improving cost and environmental performance.

54  |   TC Energy Management's discussion and analysis 2020

U.S.
The U.S. is one of the largest crude oil producing countries in the world at approximately 11 million Bbl/d in 2020. The majority of 
continental U.S. crude oil production is in the form of light tight oil from the Williston, Eagle Ford, Niobrara and Permian basins. 
In recent years, the Permian basin has become the most dominant producing region accounting for approximately 30 per cent of 
total U.S. crude oil production and is expected to grow to 6 million Bbl/d by 2035.

With light oil processing capacity fully utilized in the U.S., exports to offshore markets are the only outlets for incremental light 
tight oil production. Despite the global demand impact from the COVID-19 pandemic, U.S. crude oil exports increased to a 
record 3.1 million Bbl/d in 2020 compared to 3.0 million Bbl/d in 2019. By 2035, the U.S. is expected to export approximately             
5 million Bbl/d of predominantly light crude oil and import approximately 5 million Bbl/d of heavy crude oil.

Demand outlook
Canada’s proximity to the U.S., which is the world’s largest consumer of crude oil at over 19 million Bbl/d, and Canada’s 
significant heavy crude oil production are of strategic importance to the U.S. refining industry. Many refiners in the U.S. Midwest 
and U.S. Gulf Coast process a wide variety of crude oil, including significant amounts of heavy crude oil. This flexibility, access to 
an abundance of low-cost natural gas, proximity to light and heavy crude oil supply, economies of scale and ready access to 
markets have positioned these refineries to be among the most profitable in the world.

The U.S. Midwest and U.S. Gulf Coast refining markets have a strong reliance on heavy crude oil imports, with total imports of 
approximately 4 million Bbl/d in 2020, and a five-year average of approximately 5 million Bbl/d. The U.S. Midwest refiners have 
total refining capacity of approximately 4 million Bbl/d, which requires approximately 2 million Bbl/d of heavy crude oil. The  
U.S. Gulf Coast is the largest regional refining centre in the world with a total capacity of 10 million Bbl/d, representing more 
than half of the total U.S. refining capacity. The U.S. Gulf Coast imported approximately 2 million Bbl/d of primarily heavy crude 
oil in 2020 to meet demand.

Canada is currently the largest exporter of crude oil to the U.S. at approximately 4 million Bbl/d. Demand for heavy crude oil in 
the U.S. has been resilient and is expected to remain strong for the foreseeable future. While Canada, Venezuela and Mexico are 
the top suppliers of heavy crude oil to the U.S., the latter two countries are experiencing declining production. U.S. sanctions, 
along with the market impacts of the COVID-19 pandemic, have reduced demand for Venezuela’s heavy crude oil production. 
Mexico expects the export of Maya, its flagship heavy crude oil, to fall by almost 70 per cent between 2021 and 2023 due to the 
continued declines in its production and new domestic demand. Approximately 40 per cent of the U.S. Gulf Coast heavy crude oil 
demand is currently met by Mexican imports which presents a significant opportunity for Canada to become a more prominent 
supplier of crude oil to the U.S.

Strategic priorities
Our strategic focus is to provide transportation solutions which link growing North American supply basins to key market hubs 
and demand regions. Our intra-Alberta liquids pipelines and Keystone Pipeline System will form a contiguous path from Alberta 
through the U.S. Midwest to the U.S. Gulf Coast, which strategically positions TC Energy to provide competitive transportation 
solutions for growing supplies of Alberta heavy crude oil and U.S. light tight oil.

COVID-19 has had a material impact on energy markets which will disrupt and likely delay certain growth plans. The long-term 
contract profile supporting our business model provides stability for our existing businesses, but growth will likely be challenged 
until energy markets normalize.

Within our established risk preferences we remain committed to:
• protecting and optimizing the value of our existing assets
• expanding and leveraging our existing infrastructure
• expanding the transportation services that we offer and extending into adjacent geographies
• extending into emerging growth opportunities.

We continuously work with existing and new customers to provide pipeline transportation and terminal services. The 
combination of the scale and location of our assets assists us in attracting new volumes and in growing our business.

TC Energy Management's discussion and analysis 2020   |  55

Within Alberta, we continue to position ourselves to capture WCSB production growth. Declining Latin American crude oil 
production has increased the demand for WCSB heavy crude oil in the U.S. Gulf Coast, which has historically relied on offshore 
imports. Resolution of WCSB egress issues is expected to drive substantial production growth requiring additional transportation 
solutions. With additional commercial support, the Heartland Pipeline, TC Terminals and Hardisty terminal projects, all of which 
have received regulatory approval, would allow shippers to seamlessly connect from the Fort McMurray production region 
directly to market. This would provide shippers with a contiguous path between the WCSB and destination markets, including 
the U.S. Gulf Coast. After suspending advancement of Keystone XL, we continue to assess the implications and options available 
to us with respect to these three projects. 

With the fast-paced growth of U.S. light tight oil production and fully satisfied demand for light oil in North America, we will 
examine opportunities to expand our transportation services and extend our pipeline platform to include terminals with storage 
and marine export capabilities. Terminal connections and storage facilities encourage flows into and out of our pipeline systems, 
which we expect will help to secure long-term contracts and incremental spot volumes. We will also focus on leveraging our 
existing assets and development of projects to reach emerging growth regions such as the Williston and Denver-Julesburg basins. 

We believe our liquids pipelines business is well positioned to endure the impact of short-term commodity price fluctuations and 
supply/demand responses. Our existing operations and development projects are supported by long-term contracts where we 
provide pipeline capacity to our customers in exchange for fixed monthly payments which are not affected by commodity prices 
or throughput. The cyclical nature of commodity prices may influence the pace at which our shippers expand their operations. 
This can impact the rate of project growth in our industry, the value of our services as contracts expire, and the timing for the 
demand of transportation services and/or new liquids infrastructure.

We closely monitor the market place for strategic asset acquisitions to enhance our system connectivity or expand our footprint 
within North America. We remain disciplined in our approach and will position our business development activities strategically 
to capture opportunities within our risk preferences.

SIGNIFICANT EVENTS

Keystone XL 
Permit revocation and impairment
On January 20, 2021, U.S. President Biden revoked the existing Presidential Permit for the Keystone XL pipeline. As a result, we 
suspended the advancement of the Keystone XL pipeline project and ceased capitalizing costs, including interest during 
construction, and also ceased accruing a return on the Government of Alberta interests as of that date, while we assess our 
options along with our partner, the Government of Alberta, and other stakeholders. We expect to record a substantive, 
predominantly non-cash, after-tax charge to our earnings in first quarter 2021, which will be excluded from comparable 
earnings.

Accounting implications in first quarter 2021 and beyond will depend on the assessment and consideration of options as noted 
above, including the impacts that this had on contractual arrangements. As a result, the magnitude of the impairment charge 
and related recoveries cannot be quantified at this time. The determination of the amount of the pre-tax impairment of the 
Keystone XL assets will consider the then-carrying value of the project and any associated projects, outstanding contractual 
commitments, the estimated net recoverable value of tangible plant and equipment and specified contractual recoveries, which 
cannot be reasonably estimated until the options have been assessed and next steps have been determined. The carrying value 
of the plant, property and equipment for Keystone XL, including capitalized interest, was $2.8 billion at December 31, 2020. The 
viability of certain projects currently associated with the Keystone XL pipeline is also being reviewed for which the carrying value 
was $0.2 billion at December 31, 2020. Refer to the notes to our 2020 Consolidated financial statements for additional 
information.

Construction commencement
Prior to U.S. President Biden revoking the Presidential Permit, on March 31, 2020, we announced that we would proceed with 
construction of the Keystone XL pipeline project which commenced in April. We advanced construction of 180 km (112 miles) of 
pipeline and five pump stations in Canada, 12 pump stations in the United States, and completed the U.S./Canada border 
crossing in June 2020. 

56  |   TC Energy Management's discussion and analysis 2020

On August 5, 2020, we announced that Keystone XL had committed to construct the project using all union labor in the U.S. 
along with committing in excess of $10 million to create a Green Jobs Training Fund to help train union workers on renewable 
energy projects.

On January 17, 2021, we announced that the Keystone XL project would achieve net-zero emissions by the time it was placed into 
service in 2023. Additionally, we committed to ensure enough new renewable electricity was constructed along the pipeline 
route by 2030 to fully power the pipeline’s operational needs.

Financial matters
As part of the Keystone XL funding plan, the Government of Alberta has invested approximately US$0.8 billion in equity as of 
December 31, 2020, which substantially funded construction costs through the end of 2020. On January 4, 2021, we executed a 
US$4.1 billion project-level credit facility that is fully guaranteed by the Government of Alberta and non-recourse to us, and 
made initial cash draws on January 8, 2021, in part to repurchase a majority of the Government of Alberta’s equity interest under 
the terms of the contract. The suspension of the advancement of the project does not require immediate repayment of the debt 
as repayment is dependent upon certain other events or decisions specified in the credit facility agreement.

On November 6, 2020, we signed an agreement with Natural Law Energy, which included a potential investment by five First 
Nations in Alberta and Saskatchewan, of up to $1.0 billion in Keystone XL and future liquids projects.

Legal and permitting matters
Keystone XL continues to face legal and permitting challenges. After suspending advancement of the project on                  
January 20, 2021, we are assessing our next steps with respect to these matters.

Liquids Pipelines segmented earnings decreased by $489 million in 2020 compared to 2019 and increased by $269 million in 2019 
compared to 2018 and included the following specified items which have been excluded from our calculation of comparable EBIT 
and comparable earnings:
• a pre-tax gain in 2019 of $69 million related to the sale of an 85 per cent interest in Northern Courier
• unrealized gains and losses from changes in the fair value of derivatives related to our liquids marketing business.

A stronger U.S. dollar in 2020 had a positive impact on the Canadian dollar equivalent segmented earnings from our                  
U.S. operations compared to the same period in 2019, with a similar impact on 2019 compared to 2018.

Comparable EBITDA for Liquids Pipelines was $492 million lower in 2020 compared to 2019 primarily due to:
• lower volumes on the Keystone Pipeline System and lower contribution from liquids marketing activities driven by a global 

reduction in crude oil demand and prices due to the significant impact of the COVID-19 pandemic in 2020 and disruption to 
energy markets

• decreased earnings as a result of the sale of an 85 per cent equity interest in Northern Courier in July 2019.

Comparable EBITDA for Liquids Pipelines was $343 million higher in 2019 compared to 2018 primarily due to the net effect of:
• increased volumes on the Keystone Pipeline System 
• greater contribution from liquids marketing activities due to improved margins and volumes
• incremental contribution from the White Spruce pipeline, which was placed in service in May 2019
• decreased earnings as a result of the sale of an 85 per cent equity interest in Northern Courier in July 2019.

Depreciation and amortization
Depreciation and amortization was $9 million lower in 2020 compared to 2019 reflecting the sale of an 85 per cent equity 
interest in Northern Courier, partially offset by a stronger U.S. dollar. Depreciation and amortization was $341 million for both 
2019 and 2018 reflecting the net result of new facilities being placed in service and a stronger U.S. dollar, partially offset by the 
sale of an 85 per cent equity interest in Northern Courier.

OUTLOOK

Comparable earnings
Our 2021 earnings are expected to be lower than 2020 in both the Keystone Pipeline System and liquids marketing business as a 
result of continuing lower uncontracted volumes and decreased margins, respectively. As discussed in the Understanding our 
Liquids Pipelines business section, global crude oil demand and prices have been significantly impacted by the COVID-19 
pandemic but are expected to gradually recover to pre-COVID-19 levels by 2022.

Capital spending
We spent a total of $1.4 billion in 2020 primarily on the advancement of Keystone XL and expect to spend approximately          
$0.1 billion in 2021 on our liquids pipelines which excludes any impacts from the assessment of our options with respect to the 
Keystone XL project.

BUSINESS RISKS
The following are risks specific to our liquids pipelines business. Refer to page 88 for information about general risks related to             
TC Energy as a whole, including other operational, safety and financial risks as well as our approach to risk management.

Construction and operations
Constructing and operating our liquids pipelines to ensure transportation services are provided safely and reliably as well as 
optimizing and maintaining their availability are essential to the success of our business. Interruptions in our pipeline operations 
may impact our throughput capacity and result in reduced fixed payment revenues and spot volume opportunities. We manage 
these risks and any possible impact to the local communities and environment by investing in a highly skilled workforce and 
operating prudently using risk-based preventive maintenance programs and making effective capital investments. We use 
internal inspection equipment to check our pipelines regularly and repair them whenever necessary. 

While the majority of the costs to operate the liquids pipelines are passed through to our shippers, a portion of our volume is

Regulatory and government
Decisions by Canadian and U.S. regulators can have a significant impact on the approval, construction, operation, commercial 
and financial performance of our liquids pipelines. Shifts in government policy by existing bodies or following changes in 
government can impact our ability to grow our business. Public opinion about crude oil development and production, 
particularly in light of climate change concerns, may also have an adverse impact on the regulatory process. In conjunction with 
this, there are individuals and special interest groups that are expressing opposition to crude oil production by lobbying against 
the construction of liquids pipelines. Changing environmental requirements or revisions to the current regulatory process may 
adversely impact the timing or ability to obtain approvals for our liquids pipelines. We manage these risks by continuously 
monitoring regulatory and government developments and decisions to determine their possible impact on our liquids pipelines 
business, by building scenario analysis into our strategic outlook and by working closely with our stakeholders in the 
development and operation of our assets.

Crude oil supply and demand for pipeline capacity
A decrease in demand for refined crude oil products could adversely impact the price that crude oil producers receive for their 
product. Long-term lower crude oil prices could mean producers may curtail their investment in the further development of 
crude oil supplies. Depending on the severity, these factors would negatively impact opportunities to expand our liquids 
pipelines infrastructure and, in the longer term, to re-contract with shippers as current agreements expire.

Competition
As we continue to further develop our competitive position in the North American liquids transportation market to connect 
growing crude oil and diluent supplies between key North American producing regions and refining and export markets, we face 
competition from other midstream companies which also seek to transport these crude oil and diluent supplies to the same 
markets. Our success is dependent on our ability to offer and contract transportation services on terms that are market 
competitive.

Liquids marketing
Our liquids marketing business provides customers with a variety of crude oil marketing services including transportation, 
storage, and crude oil management, primarily through the purchase and sale of physical crude oil. Changing market conditions 
could adversely impact the value of the underlying capacity contracts and margins realized. Availability of alternative pipeline 
systems that can deliver into the same areas can also impact contract value. The liquids marketing business complies with our 
risk management policies which are described in the Other information - Enterprise risk management section.

UNDERSTANDING OUR POWER AND STORAGE BUSINESS
Our Power and Storage business is made up of two groups:
• Power
• Natural Gas Storage (Canadian, non-regulated).

Power

Canadian Power
We own approximately 1,100 MW of power supply in Canada, excluding our investment in Bruce Power. On April 29, 2020, we 
completed the sale of our Ontario natural gas-fired power plants. Results from these facilities were included in comparable 
EBITDA until their sale.

We own four natural gas-fired cogeneration facilities in Alberta and exercise a disciplined operating strategy to maximize 
revenues at these facilities. Our marketing group sells uncommitted power while also buying and selling power and natural gas 
to maximize earnings. To reduce commodity price exposure associated with uncontracted power, we sell a portion of this output 
in forward sales markets when acceptable contract terms are available while the remainder is retained to be sold in the spot 
market or under short-term forward arrangements. The objective of this strategy is to maintain adequate power supply to fulfill 
our sales obligations if we have unexpected plant outages and also enables us to capture opportunities to increase earnings in 
periods of high spot prices.

Our two eastern Canadian natural gas-fired cogeneration assets are supported by long-term contracts.

Bruce Power
Bruce Power is a nuclear power generation facility located near Tiverton, Ontario and is comprised of eight nuclear units with a 
combined capacity of approximately 6,430 MW. Bruce Power leases the facilities from OPG, has no spent fuel risk and will return 
the facilities to OPG for decommissioning at the end of the lease. We hold a 48.4 per cent ownership interest in Bruce Power.

Results from Bruce Power will fluctuate primarily due to units being offline for the MCR program and the frequency, scope and 
duration of planned and unplanned maintenance outages. Bruce Power also markets and trades power in Ontario and 
neighbouring jurisdictions under strict risk controls.

Through a long-term agreement with the IESO, Bruce Power has begun to progress a series of incremental life extension 
investments to extend the operating life of the facility to 2064. This agreement represents an extension and material 
amendment to the earlier agreement that led to the refurbishment of Units 1 and 2 at the site. Under the amended agreement, 
which took economic effect in January 2016, Bruce Power began investing in life extension activities for Units 3 through 8 to 
support the long-term refurbishment programs. Investment in the Asset Management program is designed to result in near-term 
life extensions of each of the six units up to the planned major refurbishment outages and beyond. The Asset Management 
program includes the one-time refurbishment or replacement of systems, structures or components that are not within the 
scope of the MCR program which focuses on the actual replacement of the key, life-limiting reactor components. The MCR 
program is designed to add 30 to 35 years of operational life to each of the six units.

The Unit 6 MCR outage commenced on January 17, 2020 and has an expected completion in late 2023. Investments in the 
remaining five-unit MCR program are expected to continue through 2033. Future MCR investments will be subject to discrete 
decisions for each unit with specified off-ramps available for Bruce Power and the IESO.

As part of the life extension and refurbishment agreement, Bruce Power receives a uniform contract price for all units which 
includes certain flow-through items such as fuel and lease expense recovery. The contract also provides for payment if the IESO 
requests a reduction in Bruce Power’s generation to balance the supply of, and demand for, electricity and/or manage other 
operating conditions of the Ontario power grid. The amount of the reduction is considered deemed generation, for which    
Bruce Power is paid the contract price. 

The contract price is subject to adjustments for the return of and on capital invested at Bruce Power under the Asset 
Management and MCR programs, along with various other pricing adjustments that allow for a better matching of revenues and 
costs over the long term. As part of the amended agreement, Bruce Power is also required to share operating cost efficiencies 
with the IESO for better than planned performance. These efficiencies are reviewed every three years and paid out on a monthly 
basis over the subsequent three-year period. Approximately $200 million will be paid to the IESO in 2019 to 2021 in respect to the 
operating and cost efficiencies realized in the 2016 to 2018 period, with our share being approximately $100 million.

Bruce Power is a global-supplier of Cobalt-60, a medical isotope used in the sterilization of medical equipment and to treat 
certain types of cancer. Cobalt-60 is produced during Bruce Power’s generation of electricity and is harvested during certain 
planned maintenance outages and provided for medical use. In 2020, Bruce Power supplied enough Cobalt-60 to sterilize 
between 20-25 billion pieces of medical equipment and supplies including gloves, COVID-19 swabs, single use medical 
equipment and materials used in vaccine production. Cobalt-60 is also used in the treatment of brain tumours and breast 
cancer. In addition, Bruce Power continues to advance a project to expand isotope production from its reactors with a focus on 
Lutetium-177 – another medical isotope used in the treatment of prostate cancer and neuroendocrine tumors. This project is 
being undertaken with a Canadian-based nuclear medicine partnership and the Saugeen Ojibway Nation, on whose traditional 
territory the Bruce Power facilities are located.

Canadian Natural Gas Storage
We own and operate 118 Bcf of non-regulated natural gas storage capacity in Alberta. This business operates independently from 
our regulated natural gas transmission and U.S. storage businesses. 

Our Canadian natural gas storage business helps balance seasonal and short-term supply and demand while also adding flexibility 
to the delivery of natural gas to markets in Alberta and the rest of North America. Market volatility creates arbitrage 
opportunities and our natural gas storage facilities also give us and our customers the ability to capture value from short-term 
price movements. The natural gas storage business is affected by changes in seasonal natural gas price spreads which are 
generally determined by the differential in natural gas prices between the traditional summer injection and winter withdrawal 
seasons. In addition, the business may be affected by pipeline restrictions in Alberta which limit the ability to capture price 
differentials.

Our natural gas storage business contracts with third parties, typically participants in the Alberta and interconnected 
gas markets, for a fixed fee to provide natural gas storage services on a short, medium, and/or long-term basis.

We also enter into proprietary natural gas storage transactions which include a forward purchase of our own natural gas to be 
injected into storage and a simultaneous forward sale of natural gas for withdrawal at a later period, typically during the winter 
withdrawal season. By matching purchase and sales volumes on a back-to-back basis, we lock in future positive margins, 
effectively eliminating our exposure to changes in natural gas prices.

SIGNIFICANT EVENTS

Ontario natural gas-fired power plants
On March 13, 2020, we placed the Napanee power plant into service after we completed construction and commissioning 
activities.

On April 29, 2020, we completed the sale of our Halton Hills and Napanee power plants as well as our 50 per cent interest in 
Portlands Energy Centre to a subsidiary of Ontario Power Generation Inc. for net proceeds of approximately $2.8 billion before 
post-closing adjustments. Pre-tax losses of $414 million ($283 million after tax) were recognized in 2020 and reflect the 
finalization of post-closing obligations. The total pre-tax loss of $693 million ($477 million after tax) on this transaction includes 
losses accrued during 2019 while classified as an asset held for sale as well as utilization of previously unrecognized tax loss 
benefits. This loss may be amended in the future upon the settlement of existing insurance claims. 

Bruce Power – Life Extension
The Unit 6 MCR outage commenced on January 17, 2020 and is expected to be completed in late 2023. In late March 2020, as a 
result of COVID-19 impacts, Bruce Power declared force majeure under its contract with the IESO. This force majeure notice 
covers the Unit 6 MCR and certain Asset Management work. On May 11, 2020, work on the Unit 6 MCR and Asset Management 
programs was restarted with additional prevention measures in place for worker safety related to COVID-19 and progress is 
continuing on critical path activities. The impact of the force majeure will ultimately depend on the extent and duration of 
disruptions resulting from the pandemic and Bruce Power's ability to implement mitigation measures. 

On October 1, 2020, the Unit 6 MCR project achieved a major milestone with the completion of the preparation phase and 
commencement of the Fuel Channel and Feeder Replacement Program and as of December 31, 2020 the Unit 6 MCR project 
remains on schedule and on budget. Operations on the remaining units continue as normal with scheduled outages successfully 
completed on Units 3, 4 and 5 in second quarter 2020 and on Unit 8 in fourth quarter 2020.

TC Turbines
On November 13, 2020, we acquired the remaining 50 per cent ownership interest in TC Turbines for cash consideration of  
US$67 million. TC Turbines provides industrial gas turbine maintenance, parts, repair and overhaul services. Following the 
acquisition, we began to fully consolidate TC Turbines within our financial results.

Comparable EBITDA for Power and Storage decreased by $155 million in 2020 compared to 2019 primarily due to the net effect 
of:
• the planned removal from service of Bruce Power Unit 6 on January 17, 2020 for its MCR program, partially offset by fewer 

planned and unplanned outage days on the remaining units as well as the effects of a higher realized power price. Additional 
financial and operating information on Bruce Power is provided below

• lower Canadian Power earnings largely as a result of the sale of our Ontario natural gas-fired power plants on April 29, 2020, 
although the Napanee plant added incremental earnings to that date following its March 13, 2020 in-service. In addition, we 
sold our Coolidge generating station in May 2019.

Comparable EBITDA for Power and Storage increased by $80 million in 2019 compared to 2018 primarily due to the net effect of:
• increased Bruce Power results mainly due to a higher realized power price in 2019 and lower income on funds invested for 
future retirement benefits in 2018, partially offset by lower volumes from greater outage days. Additional financial and 
operating information on Bruce Power is provided below

• lower Canadian Power contribution largely as a result of the sale of our interests in the Cartier Wind power facilities in   

October 2018 and the sale of our Coolidge generating station in May 2019. We also experienced lower results from our Alberta 
cogeneration plants due to greater outage days and a prior period billing adjustment at one of the plants.

Depreciation and amortization
Depreciation and amortization decreased by $28 million in 2020 compared to 2019 primarily due to the cessation of depreciation 
on our Halton Hills power plant in July 2019. Depreciation was $24 million lower in 2019 compared to 2018 primarily due to the 
cessation of depreciation on the Cartier Wind power facilities in June 2018, the Coolidge generating station in December 2018 
and the Halton Hills power plant in July 2019 upon their classifications as held for sale. These decreases were partially offset by 
increased depreciation at our Alberta cogeneration plants due to a reassessment of the useful life of certain components.

The Unit 6 MCR outage commenced on January 17, 2020. Excluding the Unit 6 MCR, plant availability in 2020 was 88 per cent as 
planned maintenance was completed on Bruce Units 3, 4, 5 and 8. Plant availability in 2019 was 84 per cent as planned 
maintenance was completed on Bruce Units 2, 3, 5 and 7. Plant availability in 2018 was 87 per cent as planned maintenance was 
completed on Bruce Units 1, 4 and 8. 

OUTLOOK

Comparable earnings
Our 2021 comparable earnings for the Power and Storage segment are expected to be lower than 2020 primarily as a result of a 
lower contribution from Bruce Power as described below and the sale of our Ontario natural gas-fired power plants on            
April 29, 2020.

Bruce Power equity income in 2021 is expected to be lower largely as a result of increased non-MCR planned outage days and 
higher operating costs in 2021. Planned maintenance is expected to occur on Unit 1 in the first half of 2021, on Unit 7 in the 
second half of 2021 while a Unit 3 outage is expected to begin late first quarter 2021 and be completed early fourth quarter 2021. 
The average 2021 plant availability percentage, excluding Unit 6, is expected to be in the mid-80 per cent range. 

Capital spending
We invested $0.7 billion in 2020 for our share of Bruce Power's life extension and maintenance capital projects and expect to 
invest approximately $0.8 billion in 2021.

BUSINESS RISKS
The following are risks specific to our Power and Storage business. Refer to page 88 for information about general risks related to 
TC Energy as a whole, including other operational, safety and financial risks. The Power and Storage marketing business complies 
with our risk management policies which are described in the Other information - Enterprise risk management section.

Fluctuating power and natural gas market prices
Much of the physical power generation and fuel used in our Alberta power operations is currently exposed to commodity price 
volatility. These exposures are partially mitigated through long-term contracts and hedging activities including selling and 
purchasing power and natural gas in forward markets. As contracts expire, new contracts are entered into at prevailing market 
prices. 

Our two eastern Canadian natural gas-fired assets are fully contracted and not materially impacted by fluctuating spot power 
and natural gas prices. The contracts on these assets expire in the medium to long term and, as such, it is uncertain if we will be 
able to re-contract on similar terms and may face future commodity exposure.

Our natural gas storage business is subject to fluctuating seasonal natural gas price spreads which are generally determined by 
the differential in natural gas prices between the traditional summer injection and winter withdrawal seasons. In addition, the 
business may be affected by pipeline restrictions in Alberta which limit the ability to capture price differentials.

Plant availability
Operating our plants to ensure services are provided safely and reliably as well as optimizing and maintaining their availability 
are essential to the continued success of our Power and Storage business. Unexpected outages or extended planned outages at 
our power plants can increase maintenance costs, lower plant output and sales revenues, and lower capacity payments and 
margins. We may also have to buy power or natural gas on the spot market to meet our delivery obligations. We manage this risk 
by investing in a highly skilled workforce, operating prudently, running comprehensive risk-based preventive maintenance 
programs and making effective capital investments.

TC Energy Management's discussion and analysis 2020   |  67

Regulatory
We operate in both regulated and deregulated power markets in Canada. These markets are subject to various federal and 
provincial regulations. As power markets evolve, there is the potential for regulatory bodies to implement new rules that could 
negatively affect us as a generator and marketer of electricity. These may be in the form of market rule or market design 
changes, changes in the interpretation and application of market rules by regulators, price caps, emission controls, emissions 
costs, cost allocations to generators and out-of-market actions taken by others to build excess generation, all of which may 
negatively impact the value of our assets. In addition, our development projects rely on an orderly permitting process and any 
disruption to that process can have negative effects on project schedules and costs. We are an active participant in formal and 
informal regulatory proceedings and take legal action where required. 

Compliance
Market rules, regulations and operating standards apply to our power business based on the jurisdictions in which they operate. 
Our trading and marketing activities may be subject to fair competition and market conduct requirements as well as specific 
rules that apply to physical and financial transactions in deregulated markets. Similarly, our generators may be subject to specific 
operating and technical standards relating to maintenance activities, generator availability and delivery of power and        
power-related products. While significant efforts are made to ensure we comply with all applicable statutory requirements, 
situations including unforeseen operational challenges, lack of rule clarity, and the ambiguous and unpredictable application of 
requirements by regulators and market monitors occasionally arise and create compliance risk. Deemed contravention of these 
requirements may result in mandatory mitigation activities, monetary penalties, imposition of operational limitations, or even 
prosecution.

Weather
Significant changes in temperature and weather, including the potential impacts of climate change, have many effects on our 
business, ranging from the impact on demand, availability and commodity prices, to efficiency and output capability. Extreme 
temperature and weather can affect market demand for power and natural gas and can lead to significant price volatility. 
Extreme weather can also restrict the availability of natural gas and power if demand is higher than supply. Seasonal changes in 
temperature can reduce the efficiency and production of our natural gas-fired power plants. 

Competition
We face various competitive forces that impact our existing assets and prospects for growth. For instance, our existing power 
plants will compete over time with new power capacity. New supply could come in several forms including supply that employs 
more efficient power generation technologies or additional supply from regional power transmission interconnections. We also 
face competition from other power companies in Alberta and Ontario as well as in the development of greenfield power plants.

SIGNIFICANT EVENTS

Retirement and appointment of our President and CEO
On September 21, 2020, we announced the retirement of Russ Girling as President and CEO of TC Energy and from our Board of 
Directors effective December 31, 2020. François Poirier, previously Chief Operating Officer and President, Power & Storage, 
succeeded Mr. Girling as President and CEO and joined our Board of Directors on January 1, 2021. Mr. Girling will assist Mr. Poirier 
with the transition through February 28, 2021. 

Acquisition of common units of TC PipeLines, LP
On December 15, 2020, we announced that we have entered into a definitive agreement and plan of merger to acquire all the 
outstanding common units of TC PipeLines, LP not beneficially owned by TC Energy or our affiliates in exchange for TC Energy 
common shares. Pursuant to the agreement, TC PipeLines, LP common unitholders will receive 0.70 common shares of TC Energy 
for each issued and outstanding publicly-held TC PipeLines, LP common unit. The exchange ratio reflects a value for all publicly-
held common units of TC PipeLines, LP of approximately US$1.69 billion, or 38 million TC Energy common shares based on the 
closing price of TC Energy's common shares on the New York Stock Exchange on January 19, 2021. A vote on the plan of merger 
by the unitholders of the publicly-held common units is scheduled for February 26, 2021. The transaction is expected to close in 
late first quarter 2021 subject to approval by the holders of a majority of outstanding common units of TC PipeLines, LP and 
customary regulatory approvals. Upon closing, TC PipeLines, LP will be wholly owned by TC Energy and will cease to be a 
publicly-held MLP.

Reported in Income from equity investments in the Consolidated statement of income.

Corporate segmented earnings increased by $140 million in 2020 compared to segmented losses of $70 million in 2019. 
Segmented losses increased by $16 million in 2019 compared to 2018.

Corporate segmented earnings /(losses) included foreign exchange gains and losses on our proportionate share of peso-
denominated inter-affiliate loans to the Sur de Texas joint venture from its partners. These amounts are recorded in Income from 
equity investments and have been excluded from our calculation of comparable EBITDA and EBIT as they are fully offset by 
corresponding foreign exchange losses and gains on the inter-affiliate loan receivable included in Interest income and other. 

Comparable EBITDA for Corporate was consistent in 2020 with 2019 and increased by $42 million in 2019 compared to 2018 
primarily due to decreased general and administrative costs.

Interest expense in 2020 decreased by $105 million compared to 2019 primarily due to the net effect of:
• higher capitalized interest largely related to Keystone XL and Coastal GasLink prior to its change to equity accounting upon the 

sale of a 65 per cent interest in the project on May 22, 2020, partially offset by lower capitalized interest due to the 
completion of Napanee construction in first quarter 2020. The increase on Keystone XL is largely the result of additional capital 
expenditures along with the inclusion of previously impaired capital costs in the basis for calculating capitalized interest 
following the decision to proceed with construction of the pipeline. These legacy costs were not re-capitalized but are 
included for determining capitalized interest in accordance with GAAP

• lower interest rates on reduced levels of short-term borrowings
• long-term debt issuances, net of maturities. Refer to the Financial condition section for further details on long-term debt and 

junior subordinated notes

• foreign exchange impact from a stronger U.S. dollar on translation of U.S. dollar-denominated interest.

Interest expense in 2019 increased by $68 million compared to 2018 mainly due to the net effect of:
• long-term debt and junior subordinated note issuances in 2019 and 2018, net of maturities
• foreign exchange impact from a stronger U.S. dollar on translation of U.S. dollar-denominated interest 
• increased levels of short-term borrowings
• higher capitalized interest, largely related to Keystone XL and Napanee.

AFUDC decreased by $126 million in 2020 compared to 2019. The decrease in Canadian dollar-denominated AFUDC is primarily 
due to NGTL System expansion projects placed in service. The decrease in U.S. dollar-denominated AFUDC is primarily the result 
of the suspension of recording AFUDC on Tula, effective January 1, 2020, due to ongoing construction delays on the project, 
partially offset by continuing construction of the Villa de Reyes project.

AFUDC decreased by $51 million in 2019 compared to 2018 primarily as a result of Columbia Gas and Columbia Gulf growth 
projects placed in service, partially offset by capital expenditures on our NGTL System and continued investment in our Mexico 
projects.

Interest income and other decreased by $247 million in 2020 compared to 2019 and increased by $536 million in 2019 compared 
to 2018 and included the following specific items which have been removed from our calculation of Interest income and other 
included in comparable earnings:
• foreign exchange (losses)/ gains on the peso-denominated inter-affiliate loan receivable from the Sur de Texas joint venture
• unrealized gains and losses from changes in the fair value of derivatives used to manage our foreign exchange risk. 

Interest income and other included in comparable earnings increased by $11 million in 2020 compared to 2019 primarily due to 
the net effect of:
• lower realized losses in 2020 compared to 2019 on derivatives used to manage our net exposure to foreign exchange rate 

fluctuations on U.S. dollar-denominated income

• lower interest income in 2020 related to the peso-denominated inter-affiliate loan receivable from the Sur de Texas joint 

venture due to lower interest rates and the foreign exchange impact of a weaker peso on the translation of interest income 
during the year.

Interest income and other included in comparable earnings decreased by $15 million in 2019 compared to 2018 due to the net 
effect of: 
• higher realized losses in 2019 compared to 2018 on derivatives used to manage our net exposure to foreign exchange rate 

fluctuations on U.S. dollar-denominated income

• higher interest income in 2019 related to the peso-denominated inter-affiliate loan receivable from the Sur de Texas joint 

venture due to increased amounts outstanding.

Our proportionate share of the corresponding foreign exchange gains and losses and interest expense on the peso-denominated 
inter-affiliate loans to the Sur de Texas joint venture from its partners is reflected in Income from equity investments in the  
Corporate and Mexico Natural Gas Pipelines segments, respectively, resulting in no impact on net income.

Income tax expense in 2020 decreased by $560 million compared to 2019 and increased by $322 million in 2019 compared to 
2018 and included the following specific items which have been removed from our calculation of Income tax expense included in 
comparable earnings: 
 In 2020:
• income tax valuation allowance releases of $299 million primarily related to the reassessment of deferred tax assets that were 
deemed more likely than not to be realized as a result of our March 31, 2020 decision to proceed with the Keystone XL project

• an $18 million income tax recovery related to state income taxes on the sale of certain Columbia Midstream assets.

In 2019:
• an income tax valuation allowance release of $195 million related to certain prior years' U.S. tax losses resulting from our 

reassessment of deferred tax assets that are more likely than not to be realized

• a $32 million income tax recovery on deferred income tax balances attributable to our Canadian businesses not subject to RRA 

due to an Alberta corporate income tax rate reduction enacted in June 2019.

In 2018:
• a $115 million deferred income tax recovery from an MLP regulatory liability write-off as a result of changes in the U.S. income 

tax regulations and the treatment of taxes for rate-making purposes in an MLP

• a $52 million recovery of deferred income taxes as a result of finalizing the impact of U.S. Tax Reform.

In addition, the income tax impacts of the specific items in Canadian Natural Gas Pipelines, U.S. Natural Gas Pipelines, Liquids 
Pipelines, Power and Storage and noted in other sections of this MD&A, were also removed from Income tax expense included in 
comparable earnings.

Income tax expense included in comparable earnings in 2020 decreased by $244 million compared to 2019 primarily due to lower 
flow-through income taxes in Canadian rate-regulated pipelines and higher foreign tax rate differentials.

Income tax expense included in comparable earnings in 2019 increased by $205 million compared to 2018 primarily due to higher 
comparable earnings before income taxes and lower foreign tax rate differentials, partially offset by lower flow-through income 
taxes in Canadian rate-regulated pipelines.

U.S. Tax Reform and FERC Actions
In 2017, U.S. Tax Reform was signed into law and the enacted U.S. federal corporate income tax rate was reduced from               
35 per cent to 21 per cent effective January 1, 2018. This resulted in a remeasurement of existing deferred income tax assets and 
deferred income tax liabilities related to our U.S. businesses to reflect the new lower income tax rate as at December 31, 2017. 
Given the significance of the legislation, SEC registrants were allowed to record provisional amounts at December 31, 2017 which 
could be adjusted as additional information became available, prepared or analyzed for a period not to exceed one year. We 
recognized further adjustments to the provisional amount in 2018.

In accordance with FERC Form 501-G and uncontested rate settlement filings, the accumulated deferred income tax balances for 
all pipelines held wholly or in part by TC PipeLines, LP were eliminated from their respective rate bases. As a result, net regulatory 
liabilities recorded for these assets pursuant to U.S. Tax Reform were written off, resulting in a further deferred income tax 
recovery of $115 million in 2018.

Under U.S. Tax Reform, the U.S. Treasury and the U.S. Internal Revenue Service issued final base erosion and anti-abuse tax 
regulations in 2019 and final anti-hybrid rules on April 7, 2020. The finalization of these regulations did not have a material 
impact on our 2020 Consolidated financial statements. 

Mexico Tax Reform
In 2019, Mexico passed tax reform legislation related to, among other things, interest deductibility and tax reporting. These 
changes did not have a material impact on our 2020 Consolidated financial statements.

Alberta rate reduction
On December 9, 2020, the Government of Alberta enacted the reduction of the corporate income tax rate to eight per cent  
effective July 1, 2020. This change did not have a material impact on our 2020 Consolidated financial statements.

Net (income)/ loss attributable to non-controlling interests increased by $4 million in 2020 compared to 2019 primarily due to 
higher earnings in TC PipeLines, LP, partially offset by the net loss attributable to redeemable non-controlling interest which 
includes a foreign currency translation loss and return accrual in 2020.

In 2019, Net (income)/ loss attributable to non-controlling interests increased by $478 million compared to 2018 primarily due to 
the net effect of the following items recorded in 2018: 
• a $538 million pre-tax charge related to the non-controlling interests' portion of a $722 million Bison asset impairment in       

TC PipeLines, LP 

• a $59 million pre-tax charge related to the non-controlling interests' portion of a $79 million Tuscarora goodwill impairment in 

TC PipeLines, LP 

• $97 million in pre-tax income related to the non-controlling interests' portion of Bison contract termination payments of       

$130 million received from certain customers in TC PipeLines, LP.

On consolidation, we recorded the non-controlling interests' 74.5 per cent of these transactions which have been excluded in 
the calculation of comparable earnings. Refer to the Critical accounting estimates section for more information on our goodwill 
and asset impairment testing.

In 2019, Net income attributable to non-controlling interests included in comparable earnings decreased by $22 million 
compared to 2018 largely due to lower earnings in TC PipeLines, LP, partially offset by the impact of a stronger U.S. dollar which 
increased the Canadian dollar equivalent earnings from TC PipeLines, LP.

Financial condition 

We strive to maintain strong financial capacity and flexibility in all parts of the economic cycle. We rely on our operating cash 
flows to sustain our business, pay dividends and fund a portion of our growth. In addition, we access capital markets and engage 
in portfolio management to meet our financing needs, manage our capital structure and to preserve our credit ratings. More 
information on how our credit ratings can impact our financing costs, liquidity and operations is available in our AIF available on 
SEDAR (www.sedar.com).

We believe we have the financial capacity to fund our existing capital program through predictable and growing cash flows from 
operations, access to capital markets, portfolio management, joint ventures, asset-level financing, cash on hand and substantial 
committed credit facilities. Annually, in fourth quarter, we renew and extend our credit facilities as required.

We continued to enhance our financial position in 2020 through:
• completion of the sale of the Ontario natural gas-fired power plants for net proceeds of approximately $2.8 billion before 

post-closing adjustments

• completion of the sale of a 65 per cent equity interest in Coastal GasLink LP for net proceeds of $656 million
• establishment of seven-year senior secured credit facilities for Coastal GasLink LP with current capacity of $6.8 billion. 

Immediately preceding the equity sale, $1.6 billion was drawn on these facilities and approximately $1.5 billion was paid to     
TC Energy

• TransCanada PipeLines Limited’s issuance of $2.0 billion of seven-year Medium Term Notes at a fixed rate per annum rate of 

3.8 per cent and US$1.25 billion of 10-year Senior Unsecured Notes at a fixed per annum rate of 4.1 per cent

• establishment of a US$4.2 billion Delayed Draw Term Loan at Columbia Pipeline Group, Inc., on which US$4.0 billion was 

drawn in January 2021 and the total availability under the loan agreement was reduced accordingly 

• arrangement of an additional US$2.0 billion of 364-day committed bilateral credit facilities in second quarter 2020 which were 

extinguished in fourth quarter 2020 as they were no longer required.

In addition, in early January 2021, we put in place a US$4.1 billion project-level credit facility to support the construction of the 
Keystone XL pipeline that is fully guaranteed by the Government of Alberta and non-recourse to us. We drew US$579 million on 
the credit facility on January 8, 2021, the proceeds of which were used in part to repurchase a majority of the Government of 
Alberta's Class A interests. The facility bears interest at a floating rate and matures in January 2024. The suspension of the 
advancement of the project does not require immediate repayment of the debt as repayment is dependent upon certain other 
events or decisions specified in the credit facility agreement.

These transactions demonstrate our continued ability to access capital markets under all market conditions, including during 
periods of stress such as those resulting from COVID-19. Combined with our predictable and growing cash flows from operations, 
cash on hand, substantial committed credit facilities and various other financing levers available to us, we believe we are well 
positioned to continue to fund our obligations, capital program and dividends. We do not expect COVID-19 or the recent 
volatility in commodity prices to have a material impact on our operating cash flows as a significant majority of our revenues are 
derived from long-term contracts and/or regulated cost of service business models; however, counterparty credit risk has 
heightened. Refer to the Financial risks section for additional information. 

Balance sheet analysis 
At December 31, 2020, our current assets totaled $5.2 billion and current liabilities amounted to $12.0 billion, leaving us with a 
working capital deficit of $6.8 billion compared to $5.2 billion at December 31, 2019. Our working capital deficiency is considered 
to be in the normal course of business and is managed through:
• our ability to generate predictable and growing cash flows from operations
• a total of $10.0 billion of committed revolving credit facilities of which $6.0 billion of incremental short-term borrowing 

capacity remains available, net of $4.0 billion backstopping commercial paper balances. We also have arrangements in place 
for a further $2.4 billion of demand credit facilities of which $1.2 billion remained available as of December 31, 2020 
• our access to capital markets, including through incremental credit facilities, portfolio management activities, DRP and 

Corporate ATM programs, if deemed appropriate.

Our total assets at December 31, 2020 were $100.3 billion compared to $99.3 billion at December 31, 2019 primarily reflecting 
our 2020 capital spending program, partially offset by depreciation, asset sales and the impact of a weaker U.S. dollar at        
December 31, 2020 compared to December 31, 2019 on translation of our U.S. dollar-denominated assets. 

At December 31, 2020 our total liabilities were $66.8 billion, consistent with December 31, 2019. 

Our equity at December 31, 2020 was $33.1 billion compared to $32.4 billion at December 31, 2019. The increase is principally due 
to net income net of common and preferred dividends paid, partially offset by other comprehensive loss.

At February 12, 2021, we had unused capacity of $3.0 billion, $3.0 billion, and US$2.8 billion under our TC Energy equity and TCPL 
Canadian and U.S. debt shelf prospectuses, respectively, to facilitate future access to capital markets.

Provisions of various trust indentures and credit arrangements with certain of our subsidiaries can restrict those subsidiaries' and, 
in certain cases, our ability to declare and pay dividends or make distributions under certain circumstances. In the opinion of 
management, these provisions do not currently restrict our ability to declare or pay dividends. These trust indentures and credit 
arrangements also require us to comply with various affirmative and negative covenants and maintain certain financial ratios. 
We were in compliance with all of our financial covenants at December 31, 2020.

Net cash provided by operations
Net cash provided by operations decreased by $24 million in 2020 compared to 2019 primarily due to the amount and timing of 
working capital changes which was mostly offset by higher funds generated from operations.

Net cash provided by operations increased by $527 million in 2019 compared to 2018 primarily due to the amount and timing of 
working capital changes as well as higher funds generated from operations.

Comparable funds generated from operations
Comparable funds generated from operations increased by $268 million in 2020 compared to 2019 primarily due to the 
collection of fees related to the construction of Sur de Texas and Coastal GasLink, the recovery of higher depreciation on the 
NGTL System and higher comparable earnings, partially offset by lower distributions from the operating activities of our equity 
investments.

Comparable funds generated from operations increased by $595 million in 2019 compared to 2018 primarily due the net effect of

Net cash used in investing activities decreased from $6.9 billion in 2019 to $6.1 billion in 2020 primarily as a result of proceeds 
received in 2020 on the sales of our Ontario natural gas-fired power plants and a 65 per cent equity interest in Coastal GasLink LP 
as well as the payment to dissenting Columbia Pipeline Group, Inc. shareholders in 2019, discussed below. This was partially 
offset by the cost to acquire the remaining 50 per cent ownership interest in TC Turbines.

Net cash used in investing activities decreased from $10.0 billion in 2018 to $6.9 billion in 2019 primarily as a result of proceeds 
received from the sales of certain Columbia Midstream assets and the Coolidge generating station along with lower capital 
expenditures and contributions to equity investments. This was partially offset by increased spending on capital projects under 
development, non-recurrence of Coastal GasLink recoveries realized in 2018 as well as a payment to dissenting Columbia Pipeline 
Group, Inc. shareholders in 2019 for the appraised value of their shares plus interest pursuant to a court decision which affirmed 
the original share purchase price.

Capital spending includes capacity capital expenditures, maintenance capital expenditures, capital projects in development and contributions to equity 
investments. 

Capital expenditures
Our capital expenditures in 2020 were incurred primarily for the expansion of the NGTL System and Columbia Gas projects, 
construction of Keystone XL, construction of Coastal GasLink prior to the sale of a 65 per cent equity interest as well as 
maintenance capital expenditures. Higher capital expenditures in 2020 reflect increased spending on Keystone XL and Columbia 
Gas projects, partially offset by reduced spending on the NGTL System, Napanee and the adoption of equity accounting for our 
ownership in Coastal GasLink LP after its partial sale.

Capital projects in development
Costs incurred during 2020, 2019 and 2018 on capital projects in development were predominantly attributable to spending on 
Keystone XL. The decrease in development spending in 2020 compared to 2019 is due to project costs being reflected in Capital 
expenditures subsequent to our March 31, 2020 decision to proceed with construction.

Contributions to equity investments
Contributions to equity investments increased in 2020 compared to 2019 mainly due to higher investment in Bruce Power and 
our investment in Coastal GasLink LP subsequent to its reclassification to an equity investment.

Contributions to equity investments decreased in 2019 compared to 2018 mainly due to lower investments in Millennium and  
Sur de Texas, partially offset by higher investment in Bruce Power.

Contributions to equity investments in 2019 and 2018 include our proportionate share of Sur de Texas debt financing. 

Proceeds from sales of assets
In 2020, we completed the following portfolio management transactions. All cash proceeds amounts are prior to income tax and 
post-closing adjustments: 
• the sale of our Ontario natural gas-fired power plant assets for net proceeds of approximately $2.8 billion
• the sale of a 65 per cent equity interest in Coastal GasLink LP for net proceeds of $656 million.

In addition to the proceeds from the above transactions, in 2020, we received $1.5 billion from the Coastal GasLink LP project-
level financing which preceded the equity sale.

In 2019, we completed the following transactions. All cash proceeds amounts are prior to income tax and post-closing 
adjustments:
• the sale of certain Columbia Midstream assets for proceeds of approximately US$1.3 billion
• the sale of Coolidge generating station for proceeds of US$448 million
• the sale of an 85 per cent equity interest in Northern Courier for proceeds of $144 million.

In addition to the proceeds from the above transactions, in 2019, we received a $1.0 billion distribution from the Northern 
Courier debt issuance which preceded the equity sale.

In October 2018, we completed the sale of our interests in the Cartier Wind power facilities in Québec for proceeds of 
approximately $630 million, before post-closing adjustments.

Acquisition
On November 13, 2020, we acquired the remaining 50 per cent ownership interest in TC Turbines for cash consideration of   
US$67 million.

Reimbursement of costs related to capital projects in development
In November 2018, we received $470 million in accordance with provisions in the agreements with the LNG Canada joint venture 
participants allowing them to reimburse us for their share of pre-FID costs.

Other distributions from equity investments
Other distributions from equity investments in 2019 and 2018 primarily reflect our proportionate share of Bruce Power and 
Northern Border financings undertaken to fund their respective capital programs and to also make distributions to their partners. 
In 2019 and 2018, we received distributions of $120 million and $121 million, respectively, from Bruce Power in connection with 
their issuance of senior notes in the capital markets. We also received distributions of $66 million in 2019 from Northern Border 
originating from a draw on its revolving credit facility to manage capitalization levels.

Net cash provided by financing activities decreased by $1.5 billion in 2020 compared to 2019 primarily due to the net repayment 
of notes payable in 2020, the issuance of junior subordinated notes in 2019 and higher cash dividends and distributions paid in 
2020 as DRP participation was no longer satisfied through the issuance of common shares from treasury at a discount. This was 
partially offset by higher issuances of long-term debt and contributions in support of Keystone XL construction in the form of a 
redeemable non-controlling interest.

Net cash provided by financing activities decreased by $2.1 billion in 2019 compared to 2018 due to lower issuances of long-term 
debt and common shares, partially offset by junior subordinated notes issued in 2019 and increased notes payable outstanding.

The principal transactions reflected in our financing activities are discussed in further detail below.

On April 28, 2020, Coastal GasLink LP entered into secured long-term project financing credit facilities. On May 22, 2020, TC Energy completed the sale of a         
65 per cent equity interest in Coastal GasLink LP and subsequently accounts for its remaining 35 per cent interest using the equity method. Immediately 
preceding the equity sale, Coastal GasLink LP made an initial draw of $1.6 billion on the credit facilities, of which approximately $1.5 billion was paid to               
TC Energy.

The net proceeds of the above TCPL debt issuances were used for general corporate purposes, to fund our capital program and to 
repay existing debt.

In addition, on January 4, 2021, we put in place a US$4.1 billion project-level credit facility to support the construction of the 
Keystone XL pipeline that is fully guaranteed by the Government of Alberta and non-recourse to us. We drew US$579 million on 
the credit facility on January 8, 2021, the proceeds of which were used in part to repurchase a majority of the Government of 
Alberta's Class A interests. The facility bears interest at a floating rate and matures in January 2024. The suspension of the 
advancement of the project does not require immediate repayment of the debt as repayment is dependent upon certain other 
events or decisions specified in the credit facility agreement. Refer to the notes to our 2020 Consolidated financial statements 
for additional information.

On December 9, 2020, our subsidiary, Columbia Pipeline Group, Inc., entered into a US$4.2 billion Delayed Draw Term Loan due 
in June 2022, bearing interest at a floating rate, to be used for general corporate purposes. In January 2021, US$4.0 billion was 
drawn on the Delayed Draw Term Loan and the total availability under the loan agreement was reduced accordingly.

Contributions from Redeemable non-controlling interest
During 2020, our Keystone XL subsidiaries issued $1,033 million of Class A Interests to the Government of Alberta. For more 
information on the redeemable non-controlling interest, refer to the notes to our 2020 Consolidated financial statements.

Dividend Reinvestment Plan
Under the DRP, eligible holders of common and preferred shares of TC Energy can reinvest their dividends and make optional 
cash payments to obtain additional TC Energy common shares. From July 1, 2016 to October 31, 2019, common shares were 
issued from treasury at a discount of two per cent to market prices over a specified period. 

Commencing with the dividends declared October 31, 2019, common shares purchased under TC Energy’s DRP are no longer 
satisfied with shares issued from treasury at a discount, but rather are acquired on the open market at 100 per cent of the 
weighted average purchase price.

TC Energy Corporate ATM Program
In June 2017, we established an ATM program that allowed us to issue common shares from treasury from time to time, at the 
prevailing market price. The ATM program, which was effective for a 25-month period, was initially established with an 
aggregate issuance limit of up to $1.0 billion in common shares or the U.S. dollar equivalent. In June 2018, we replenished the 
capacity available under the ATM program to allow for the issuance of additional common shares from treasury of up to           
$1.0 billion for a revised aggregate total of $2.0 billion or the U.S. dollar equivalent. 

In 2018, 20 million common shares were issued under the ATM program at an average price of $56.13 per share for proceeds of 
$1.1 billion, net of approximately $10 million of related commissions and fees.

In July 2019, the ATM program expired with no common shares issued in 2019.

On December 7, 2020, we established a new ATM program that allows us to issue common shares from treasury having an 
aggregate gross sales price of up to $1.0 billion, or the U.S. dollar equivalent, to the public from time to time, at our discretion, 
at the prevailing market price when sold through the TSX, the NYSE, or any other applicable existing trading market for TC Energy 
common shares in Canada or the U.S. While not a component of our base funding plan, the ATM program, which is effective for a 
25-month period, provides additional financial flexibility in support of our consolidated credit metrics and capital program and 
may be activated if, and as, deemed appropriate. No common shares were issued under the new program in 2020.

TC PipeLines, LP

ATM equity issuance program
In 2018, TC PipeLines, LP issued 0.7 million common units under its ATM program, which authorized TC PipeLines, LP from time to 
time to offer and sell, through sales agents, common units representing limited partner interests. In 2018, TC PipeLines, LP‘s ATM 
program generated net proceeds of approximately $39 million. In August 2019, this ATM program expired with no common unit 
issuances in 2019. At December 31, 2020 and 2019, our ownership interest in TC PipeLines, LP was 25.5 per cent.

Demand rates are subject to change. The contractual obligations in the table are based on demand volumes only and exclude variable charges incurred when 
volumes flow.
Amounts are primarily for capital expenditures and contributions to equity investments for capital projects. Amounts are estimates and are subject to variability 
based on timing of construction and project requirements.
Includes estimates of certain amounts which are subject to change depending on plant-fired hours, the consumer price index, actual plant maintenance costs, 
plant salaries as well as changes in regulated rates for fuel transportation.

Outlook
Our capital program is comprised of $20 billion of secured projects and $8 billion of projects under development, which are 
subject to key commercial or regulatory approvals. The program is expected to be financed through our growing internally 
generated cash flows and a combination of other funding options including:
• senior debt
• hybrid securities
• preferred shares
• asset sales
• project financing
• potential involvement of strategic or financial partners.

In addition, we may access additional funding options below, as deemed appropriate:
• common shares issued from treasury under our DRP
• common shares issued under our ATM program
• discrete common equity issuance.

GUARANTEES

Northern Courier 
As part of our role as operator of the Northern Courier pipeline, we have guaranteed the financial performance of the pipeline 
related to delivery and terminalling of bitumen and diluent and contingent financial obligations under sub-lease agreements. 
The guarantees have terms ranging to 2055.

At December 31, 2020, our potential exposure under the Northern Courier guarantees was estimated to be $300 million with a 
carrying amount of approximately $26 million. 

Sur de Texas
We and our partner on the Sur de Texas pipeline, IEnova, have jointly guaranteed the financial performance of the entity which 
owns the pipeline. Such agreements include a guarantee and a letter of credit which are primarily related to the delivery of 
natural gas. The guarantees have terms extending up to June 2021.

At December 31, 2020, our share of potential exposure under the Sur de Texas pipeline guarantees was estimated to be            
$100 million with a carrying amount of less than $1 million. 

Bruce Power
We and our joint venture partner on Bruce Power, BPC Generation Infrastructure Trust, have each severally guaranteed certain 
contingent financial obligations of Bruce Power related to a lease agreement. The Bruce Power guarantee has a term to 2023.

At December 31, 2020, our share of the potential exposure under the Bruce Power guarantee was estimated to be $88 million 
with no carrying amount. 

Other jointly-owned entities
We and our partners in certain other jointly-owned entities have also guaranteed (jointly, severally, jointly and severally, or 
exclusively) the financial performance of these entities. Such agreements include guarantees and letters of credit which are 
primarily related to delivery of natural gas, construction services including purchase agreements and the payment of liabilities. 
The guarantees have terms ranging to 2043.

Our share of the potential exposure under these assurances was estimated at December 31, 2020 to be approximately $78 million 
with a carrying amount of $4 million. In certain cases, if we make a payment that exceeds our ownership interest, the additional 
amount must be reimbursed by our partners.

OBLIGATIONS – PENSION AND OTHER POST-RETIREMENT BENEFIT PLANS
In 2021, we expect to make funding contributions of approximately $128 million for the defined benefit pension plans, 
approximately $6 million for other post-retirement benefit plans and approximately $59 million for the savings plans and defined 
contribution pension plans. In addition, we expect to provide an additional estimated $13 million letter of credit to the Canadian 
defined benefit plan for solvency funding requirements.

In 2020, we made funding contributions of $124 million to our defined benefit pension plans, $9 million for other                    
post-retirement benefit plans and $58 million for the savings plan and defined contribution pension plans. We also provided an 
additional $13 million letter of credit to the Canadian defined benefit plan for funding of solvency requirements.

Outlook
The next actuarial valuation for our pension and other post-retirement benefit plans will be carried out as at January 1, 2021. 
Based on current market conditions, we expect funding requirements for these plans to approximate 2021 levels for several 
years. This will allow us to amortize solvency deficiencies in the plans, in addition to normal service costs. We do not expect 
COVID-19 to impact our funding requirements.

The net benefit cost for our defined benefit and other post-retirement plans increased to $114 million in 2020 from $83 million in 
2019 mainly due to lower discount rates.

86  |   TC Energy Management's discussion and analysis 2020

Future net benefit costs and the amount we will need to contribute to fund our plans will depend on a range of factors 
including:
• interest rates
• actual returns on plan assets
• changes to actuarial assumptions and plan design
• actual plan experience versus projections
• amendments to pension plan regulations and legislation.

We do not expect future increases in the level of funding needed to maintain our plans to have a material impact on our liquidity 
or financial condition.

ENTERPRISE RISK MANAGEMENT
Risk management is integral to the successful operation of our business. Our strategy is to ensure that our risks and related 
exposures are aligned with our business objectives and risk tolerance. We manage risk through a centralized enterprise risk 
management (ERM) process which identifies risks that could materially impact the achievement of our strategic objectives, 
including ESG-related risks.

Our Board of Directors' Governance Committee oversees our ERM activities, which includes ensuring appropriate management 
systems are in place to identify and manage our risks, ensuring adequate Board oversight of our risk management policies, 
programs and practices. Other Board committees oversee specific types of risk: 
• the Human Resources Committee oversees executive resourcing, organizational capabilities and compensation risk to ensure 

human and labour policies and remuneration practices align with our overall business strategy
• the HSSE Committee oversees operational, health, safety, sustainability and environmental risk 
• the Audit Committee oversees management's role in managing financial risk, including market risk, counterparty credit risk 

and cyber security.

Our executive leadership team is accountable for developing and implementing risk management plans and actions, and 
effective risk management is reflected in their compensation.

We have discussed the risks that are specific to each of our business segments in their respective sections of this MD&A. The 
following is a summary of certain general risks that affect our company across all of our operations and are being continuously 
monitored.

Risk and Description

Impact

Monitoring and Mitigation

Business interruption

Operational risks, including equipment 
malfunctions and breakdowns, labour 
disputes, a pandemic, natural disasters 
and other catastrophic events including 
those related to climate change, acts of 
terror and sabotage.

Decrease in revenues and increase in 
operating costs, legal proceedings or 
regulatory actions, or other expenses all 
of which could reduce our earnings. 
Losses not recoverable through tolls or 
contracts or covered by insurance could 
have an adverse effect on operations, 
cash flows and financial position. Certain 
events could lead to risk of injury and 
environmental damage. 

Our management system, TOMS, includes our corporate 
health, safety, sustainability, environment and asset 
integrity programs to prevent incidents and protect 
employees, contractors, members of the public, the 
environment and our assets. TOMS includes incident, 
emergency and crisis management programs to ensure   
TC Energy can effectively respond to operational risk 
events, minimize loss or injury and enhance our ability to 
resume operations. This is supported by our business 
continuity program that identifies critical business 
processes and develops corresponding business 
resumption plans. We also have a comprehensive 
insurance program to mitigate a certain portion of these 
risks, but insurance does not cover all events in all 
circumstances.

Cyber security

We rely on our information technology 
to process, transmit and store 
electronic information, including 
information we use to safely operate 
our assets. We continue to face cyber 
security risks and could be subject to 
cyber security events directed against 
our information technology. The 
methods used to obtain unauthorized 
access, disable or degrade service or 
sabotage systems are constantly 
evolving and may be difficult to 
anticipate or to detect for long periods 
of time.

A breach in the security of our 
information technology could expose our 
business to a risk of loss, misuse or 
interruption of critical information and 
functions. This could affect our 
operations, damage our assets, result in 
safety incidents, damage to the 
environment, and/or result in 
reputational harm, competitive 
disadvantage, regulatory enforcement 
actions and potential litigation, which 
could have a material adverse effect on 
our operations, financial position and 
results of operations.

We have a comprehensive cyber security strategy which 
aligns with industry and recognized standards for cyber 
security. This strategy is regularly reviewed and updated, 
and the status of our cyber security program is reported to 
the Audit Committee on a quarterly basis. The program 
includes cyber security risk assessments, continuous 
monitoring of networks and other information sources for 
threats to the organization, comprehensive incident 
response plans/processes and a robust cyber security 
awareness program for employees and contractors. We 
have insurance which may cover losses from physical 
damage to our facilities as a result of a cyber security 
event, but insurance does not cover all events in all 
circumstances.

Risk and Description

Impact

Monitoring and Mitigation

Our reputation with stakeholders, 
including Indigenous communities, can 
have a significant impact on our 
operations and projects, infrastructure 
development and overall reputation. 
Should investors develop negative 
perceptions regarding our energy 
infrastructure business, future access to 
investment capital could be negatively 
impacted.

Our four core values – safety, responsibility, collaboration 
and integrity – guide us in building and maintaining all of 
our key relationships as well as our interactions with 
stakeholders. We are proud of the strong relationships we 
have built with stakeholders across our geographies, and 
we are continuously seeking ways to strengthen these 
relationships. Beyond our core values, we have specific 
stakeholder programs and policies that shape our 
interactions, clarify expectations, assess risks and facilitate 
mutually beneficial outcomes. Our most recent Report on 
Sustainability includes details on our specific 
commitments related to safety, partnerships with 
Indigenous communities, focus on landowner 
relationships and our workplace inclusion and diversity. 

Reputation and relationships

Our operations and growth prospects 
require us to have strong relationships 
with key stakeholders including 
customers, Indigenous communities, 
landowners, suppliers, investors, 
governments and government 
agencies, and environmental non-
governmental organizations. 
Inadequately managing expectations 
and concerns important to 
stakeholders, including those related to 
climate change, could affect our 
reputation and our ability to operate 
and grow, as well as our access to and 
cost of capital.

Access to capital at a competitive cost

We require substantial amounts of 
capital in the form of debt and equity 
to finance our portfolio of growth 
projects and maturing debt obligations 
at costs that are sufficiently lower than 
the returns on our investments.

Significant deterioration in market 
conditions for an extended period of time 
and changes in investor and lender 
sentiment could affect our ability to 
access capital at a competitive cost, 
which could negatively impact our ability 
to deliver an attractive return on our 
investments or inhibit our growth.

Capital allocation strategy

To be competitive, we must offer 
integral energy infrastructure services 
in supply and demand areas, and for 
forms of energy that are attractive to 
customers.

Should alternative lower-carbon forms of 
energy result in decreased demand for 
our services on an accelerated timeline 
versus our pace of depreciation, the value 
of our long-lived energy infrastructure 
assets could be negatively impacted. 

Execution and capital costs

Investing in large infrastructure 
projects involves substantial capital 
commitments and associated execution 
risks based on the assumption that 
these assets will deliver an attractive 
return on investment in the future.

While we carefully determine the 
expected cost of our capital projects, 
under some commercial arrangements 
we bear capital cost overrun and 
schedule risk which may decrease our 
return on these projects.

We operate within our financial means and risk tolerances, 
maintain a diverse array of funding levers and also utilize 
portfolio management as an important component of our 
financing program. In addition, we have candid and 
proactive engagement with the investment community, 
including credit rating agencies, with the objective of 
keeping them apprised of developments in our business 
and factually communicating our prospects, risks and 
challenges, including those related to ESG as well as 
receiving their feedback. We also conduct research around 
the ESG preferences of our investors and financial 
partners, which are considered in our ESG and 
sustainability approach and reporting.

We have a diverse portfolio of assets and use portfolio 
management to divest of non-strategic assets, effectively 
rotating capital while adhering to our risk preferences and 
focus on per share metrics. We conduct analyses to 
identify resilient supply sources as part of our energy 
fundamentals and strategic development reviews. We 
recover depreciation through our regulated pipeline rates 
which is an important lever to accelerate or decelerate the 
return of capital from a substantial portion of our assets. 
We also monitor signposts including customer, regulatory 
and government decisions as well as innovative 
technology development to inform our capital allocation 
strategy and adapt to changing market conditions. 

Our Project Governance Program supports project 
execution and operational excellence. The program aligns 
with TOMS which provides the framework and standards 
to optimize project execution, ensuring timely and on 
budget completion. We prefer to contractually structure 
our projects to recover development costs if a project 
does not proceed along with mechanisms to minimize the 
impact should cost overruns occur. However, under some 
commercial arrangements, we share or bear the cost of 
execution risk. Additionally, we can utilize project 
financing and/or involve partners in our projects to 
manage capital at risk.

Health, safety, sustainability and environment
The Board's HSSE committee oversees operational risk, people and process safety, security of personnel, environmental and 
climate change related risks, and monitors development and implementation of systems, programs and policies relating to HSSE 
matters through regular reporting from management. We use an integrated management system that establishes a framework 
for managing these risks and is used to capture, organize, document, monitor and improve our related policies, programs and 
procedures.

Our management system, TOMS, is modeled after international standards, including the International Organization for 
Standardization (ISO) standard for environmental management systems, ISO 14001, and the Occupational Health and Safety 
Assessment Series for occupational health and safety. TOMS conforms to applicable industry standards and complies with 
applicable regulatory requirements. It covers our projects and operations and follows a continuous improvement cycle organized 
into four key areas:
• Plan – risk and regulatory assessment, objective and target setting, including achieving total recordable case rate targets and 

striving for zero incidents as well as defining roles and responsibilities

• Do – development and implementation of programs, procedures and standards to manage operational risk
• Check – incident reporting, investigation, assurance activities, including internal and external audits, and performance 

monitoring

• Act – non-conformance, non-compliance and opportunities for improvement are managed with performance reviewed by 

management.

The HSSE committee reviews HSSE performance and operational risk management. It receives detailed reports on:
• overall HSSE corporate governance
• operational performance and preventive maintenance metrics
• asset integrity programs
• emergency preparedness, incident response and evaluation
• people and process safety performance metrics
• our Environment Program, which is part of TOMS
• developments in and compliance with applicable legislation and regulations, including those related to the environment
• prevention, mitigation and management of risks related to HSSE matters, including climate change or business interruption 

risks, such as pandemics, that may adversely impact TC Energy

• sustainability matters, including social, environmental and climate change related risks and opportunities
• our Occupational Health and Hygiene Program, which includes physical and mental health
• management's approach to voluntary public disclosure on HSSE matters. 

Health, safety and asset integrity
The safety of our employees, contractors and the public as well as the integrity of our pipelines, power and storage 
infrastructure, are a top priority. All assets are designed, constructed and commissioned with full consideration given to safety 
and integrity, and are placed in service only after all necessary requirements, both regulatory and internal, have been satisfied. 

In 2020, we spent $1.5 billion for pipeline integrity on the natural gas and liquids pipelines we operate, a $286 million increase 
from 2019 in part due to increased capital expenditures related to pipeline replacements to address population growth adjacent 
to our pipeline systems, modifications to facilitate the inline inspection of additional pipeline segments, an increased number of 
inline inspections and corresponding excavations plus repairs on some pipeline systems. Pipeline integrity spending will fluctuate 
based on the results of annual risk assessments conducted on our pipeline systems and evaluations of information obtained from 
recent inspections, incidents and maintenance activities.

Under the approved regulatory models in Canada, non-capital pipeline integrity expenditures on CER-regulated natural gas 
pipelines are generally treated on a flow-through basis and, as a result, fluctuations in these expenditures generally have no 
impact on our earnings. Similarly, under our Keystone Pipeline System contracts, pipeline integrity expenditures are recovered 
through the tolling mechanism and, as a result, generally have no impact on our earnings. Non-capital pipeline integrity 
expenditures on our U.S. natural gas pipelines are primarily treated as operations and maintenance expenditures, and are 
typically recoverable through tolls approved by FERC.

90  |   TC Energy Management's discussion and analysis 2020

Spending associated with process safety and various integrity programs for the power and storage assets we operate is used to 
minimize risk to employees, contractors, the public, equipment, and the surrounding environment, and also prevent disruptions 
to serving the energy needs of our customers.

As described in the Business interruption discussion above, we have a set of procedures in place to manage our response to 
natural disasters, which include catastrophic events such as forest fires, tornadoes, earthquakes, floods, volcanic eruptions and 
hurricanes. The procedures, which are included in our Emergency Management Program, are designed to help protect the health 
and safety of our employees and contractors, minimize risk to the public and limit the potential for adverse effects on the 
environment.

We are committed to protecting the health and safety of all individuals involved in our activities. Our Occupational Health and 
Hygiene Program provides comprehensive strategies for health promotion and protection. We are committed to delivering 
effective programs that:
• reduce the human and financial impact of illness and injury
• ensure fitness for work
• strengthen worker resiliency 
• build organizational capacity by focusing on individual well-being, health education and improved working conditions to 

sustain a productive workforce

• increase mental well-being awareness, provide various mental health supports and training to employees and leaders, 

measure the success of programs and improve psychological health and safety.

In response to the COVID-19 pandemic, with guidance from government and public health authorities, we have implemented 
enhanced COVID-19 health and safety protocols and procedures to protect our employees, contractors and other stakeholders.

Environmental risk, compliance and liabilities
TOMS provides requirements for our day-to-day work to protect employees, contractors, our workplace and assets, the 
communities in which we work and the environment. It conforms to external industry consensus standards and voluntary 
programs plus complies with applicable legislative requirements. Under TOMS, mandated programs set requirements to manage 
specific risk areas for TC Energy, including the Environment Program, which is a documented set of processes and procedures 
that identifies our requirements to proactively and systematically manage environmental hazards and risks throughout the 
lifecycle of our assets. As part of our Environment Program, we complete environmental assessments for our projects which 
include field studies that examine existing natural resources, biodiversity and land use along our proposed project footprint such 
as vegetation, soils, wildlife, water resources, wetland, and protected areas. To conserve and protect the environment during 
construction, information gathered for an environmental impact assessment is used to develop project-specific environmental 
protection plans. Additionally, the Environment Program, which applies to all of our operations, includes practices and 
procedures to manage potential adverse environmental effects to these resources during the full lifecycle of our facilities.

Our primary sources of risk related to the environment include:
• changing regulations and requirements coupled with increased costs related to impacts on the environment 
• product releases, including crude oil, diluent and natural gas, that may cause harm to the environment (land, water and air)
• use, storage and disposal of chemicals and hazardous materials
• natural disasters and other catastrophic events, including those related to climate change, that may impact our operations.

Our assets are subject to federal, state, provincial and local environmental statutes and regulations governing environmental 
protection, including air and GHG emissions, water quality, species at risk, wastewater discharges and waste management. 
Operating our assets requires obtaining and complying with a wide variety of environmental registrations, licenses, permits and 
other approvals and requirements. Failure to comply could result in administrative, civil or criminal penalties, remedial 
requirements, or orders affecting future operations.

Through the implementation of our Environment Program, we continually monitor our facilities for compliance with all material 
legal and regulatory environmental requirements across all jurisdictions where we operate. We also comply with all material 
legal and regulatory permitting requirements in our project routing and development. We routinely monitor proposed changes 
in environmental policy, legislation and regulation, and where the risks are uncertain or have the potential to affect our ability to 
effectively operate our business, we comment on proposals independently or through industry associations.

TC Energy Management's discussion and analysis 2020   |  91

We are not aware of any material outstanding orders, claims or lawsuits against us related to releasing or discharging any 
material into the environment or in connection with environmental protection.

Compliance obligations can result in significant costs associated with installing and maintaining pollution controls, fines and 
penalties resulting from any failure to comply, and potential limitations on operations. Remediation obligations can result in 
significant costs associated with the investigation and remediation of contaminated properties, and with damage claims arising 
from the contamination of properties.

The timing and complete extent of future expenditures related to environmental matters is difficult to estimate accurately 
because:
• environmental laws and regulations and their interpretations and enforcement change
• new claims can be brought against our existing or discontinued assets
• our pollution control and clean-up cost estimates may change, especially when our current estimates are based on preliminary 

site investigations or agreements

• new contaminated sites may be found, or what we know about existing sites could change
• where there is potentially more than one responsible party involved in litigation, we cannot estimate our joint and several 

liability with certainty.

At December 31, 2020, accruals related to these obligations totaled $24 million (2019 – $29 million), representing the estimated 
amount we will need to manage our currently known environmental liabilities. We believe we have considered all necessary 
contingencies and established appropriate reserves for environmental liabilities, however, a risk exists that unforeseen matters 
may arise requiring us to set aside additional amounts. We adjust reserves regularly to account for changes in liabilities.

Climate change and related regulation 
We own assets and have business interests in a number of regions subject to GHG emissions regulations, including GHG emissions 
management and carbon pricing policies. In 2020, we incurred $64 million (2019 – $69 million) of expenses under existing 
carbon pricing programs. Across North America, there are a variety of new and evolving initiatives and policies in development at 
the federal, regional, state and provincial level aimed at reducing GHG emissions. We actively monitor and submit comments to 
regulators as these new and evolving initiatives are undertaken and policies implemented. We support transparent climate 
change policies that promote sustainable and economically responsible natural resource development. Our assets in specific 
geographies are currently subject to GHG regulations and we expect that the number of our assets subject to GHG regulations 
will continue to increase over time across our footprint. Changes in regulations may result in higher operating costs or other 
expenses or higher capital expenditures to comply with possible new regulations. 

Existing policies
Canadian jurisdictions
• ECCC's methane reduction regulations that detail requirements to reduce methane emissions through operational and capital 

modifications came into effect on January 1, 2020. Alberta, British Columbia and Saskatchewan have drafted their own 
methane regulations that take the place of the federal regulation in those jurisdictions; however, for federally-regulated 
facilities in these jurisdictions, the federal methane regulation is applicable. Compliance with the regulations requires an 
increased level of leak detection and repair (LDAR) surveys and measurements to quantify emission reductions and associated 
reporting. Power facilities are not affected by this regulation at the current time

• the Federal OBPS regulation imposes carbon pricing for larger industrial facilities and sets federal benchmarks for GHG 

emissions for various industry sectors. This federal regulation is in effect in the provinces of Ontario, Manitoba, Saskatchewan, 
and New Brunswick as those jurisdictions did not have a provincial plan in place for carbon pricing which met the criteria of 
the Government of Canada when the policy was developed. Our assets across Canada are subject to some type of carbon 
pricing as a result

• new requirements for federally regulated project applications under the Impact Assessment Agency were recently introduced 

as the Strategic Assessment of Climate Change, requiring a project proponent to provide a credible plan for a proposed project 
to achieve net-zero emissions by 2050. As well, in August 2020, the CER published a revision to its Filing Manual, integrating 
the Strategic Assessment of Climate Change, which includes the requirement that projects regulated by the CER with a lifetime 
beyond 2050 must also include a credible plan to achieve net zero emissions by 2050. We are assessing the implications of this 
requirement as part of our project implementation process

92  |   TC Energy Management's discussion and analysis 2020

• B.C. implemented a tax on GHG emissions from fossil fuel combustion. While we are subject to this tax, the compliance costs 
are recovered through tolls. Additionally, B.C. established The CleanBC program for industry which directs a portion of the 
carbon tax paid by industry to fund incentives for cleaner operations by means of performance benchmarking or funding 
emissions reduction projects

• in Alberta, the existing Carbon Competitive Incentive Regulation (CCIR) has been replaced with the Technology Innovation and 

Emissions Reduction (TIER) regulation as of January 1, 2020. The CCIR required established industrial facilities with GHG 
emissions above a certain threshold to reduce their emissions below an intensity baseline. The TIER system follows a similar 
regulatory framework as the CCIR and covers all of our natural gas pipelines and power and storage assets in Alberta. 
Compliance costs with respect to our regulated Canadian natural gas pipelines are recovered through tolls. A portion of the 
compliance costs for the power and storage assets are recovered through market pricing and hedging activities

• Québec has a GHG cap-and-trade program under the Western Climate Initiative (WCI) GHG emissions market. In Québec, our 
Bécancour cogeneration plant is subject to this program. The government allocates free emission units for the majority of 
Bécancour's compliance requirements. The remaining requirements were met with GHG instruments purchased at auctions or 
secondary markets. The costs of these emissions units are recovered through commercial contracts. The Canadian Mainline 
natural gas pipeline facilities in Québec are also subject to this program and compliance instruments have been purchased in 
order to comply with the requirements of this initiative

• Ontario does not currently have carbon pricing regulation. Therefore, TC Energy’s electricity and pipeline facilities in this 

jurisdiction are subject to the Canadian Federal OBPS. The Government of Ontario is in the process of developing a provincial 
industrial carbon pricing program, the Emissions Performance Standards (EPS). The Ontario EPS system received equivalency 
status from the Federal Government in August 2020; however, the implementation timeframe and compliance requirements 
are not finalized. Until that time, Federal OBPS applies to our Canadian Mainline operations in the province and costs under 
this program are recovered in tolls. At this time, we do not anticipate any material impact to the financial performance of our 
Ontario natural gas pipeline facilities as a result of this program. 

U.S. jurisdictions
• Federal: On August 13, 2020, the U.S. Environmental Protection Agency (EPA) issued two final rules to lessen the administrative 
and compliance cost burden on the oil and gas industry related to the New Source Performance Standards (NSPS). One of the 
rules, the Methane Policy Rule, was a policy amendment which notably removed the transmission and storage sector from the 
source category and rescinded the NSPS applicable to those sources. The second rule, the Technical Amendment, changed 
several requirements including monitoring and repair schedules, recordkeeping and reporting requirements plus provided 
industry with the option to meet certain state requirements in lieu of federal requirements. Lawsuits brought by 
environmental groups and various state and local governments against both rules are pending in the D.C. Circuit Court of 
Appeals

• California: Tuscarora facilities are subject to the California Air Resources Board's LDAR program requiring owners/operators of 
oil and gas facilities to monitor and repair methane leaks. Beginning January 1, 2020, thresholds for leak repair were reduced. 
California also has a GHG cap-and-trade program linked with Quebec's program through the WCI

• Washington: In 2016, the Washington Department of Ecology (Ecology) adopted the Clean Air Rule (Rule) which established a 
cap and reduce program to regulate GHG emissions from major stationary sources, petroleum product producers, importers 
and distributors and natural gas distributors within Washington. The Rule was challenged in court and on January 16, 2020 the 
Washington State Supreme Court (Washington Supreme Court) ruled that while Ecology has the authority to regulate actual 
emitters, it cannot regulate indirect emitters of GHG emissions. As such, it vacated the rule only as it applied to indirect 
sources of GHGs such as natural gas distributors and fuel suppliers. The Washington Supreme Court remanded the case to the 
Superior Court to determine how to separate the rule. The impact to our GTN assets is being evaluated

• Pennsylvania: The Pennsylvania Department of Environmental Protection has an LDAR program for new source installations 

which require leak repair within 15 days of discovery

• Maryland: Effective November 16, 2020, the Maryland Department of the Environment (MDE) finalized a methane regulation 

program for new and existing natural gas facilities that includes an LDAR program, emission control and reporting 
requirements, plus a requirement to notify not only the MDE, but also the public of any events above a specific threshold. We 
have one electric-powered compressor station and associated pipeline segments impacted by this regulation.

TC Energy Management's discussion and analysis 2020   |  93

Mexico jurisdictions
• the General Climate Change Law (LGCC) establishes various public policy instruments, including the National Emissions 
Registry (RENE) and its regulations, which allow for the compilation of information on the emission of compounds and 
greenhouse gases of the different productive sectors of the country. The LGCC defines the National Inventory of greenhouse 
gases and compounds as the document that contains the estimate of anthropogenic emissions by sources and absorption by 
sinks in Mexico

• in 2018, the Government of Mexico published a regulation that established guidelines for the prevention and control of 
methane emissions from the hydrocarbon sector. Companies are required to prepare a Program for the Comprehensive 
Prevention and Control of Methane Emissions (PPCIEM) which includes identification of sources of methane, quantification of 
baseline emissions, and an estimate of the expected emission reductions from prevention and control activities. This 
regulation requires the PPCIEM, through which operational and technological practices are adopted, to determine a reduction 
goal that must be met within a period not exceeding six calendar years from the delivery of the PPCIEM. TC Energy developed 
and applied the PPCIEM to all of its facilities in Mexico in second quarter 2020

• in 2019, the Secretariat of Environment and Natural Resources published an agreement to progressively and gradually establish 
an emissions commerce system in Mexico and comply with the LGCC. It will function as a three-year pilot from 2020 to 2022 
that allows the Secretariat to test the design and rules of the system as well as evaluate its performance and then propose 
adjustments for a subsequent operational phase after 2022.

Anticipated policies
Canadian jurisdictions
• the Government of Canada is developing the Clean Fuel Standard (CFS) to achieve reductions in greenhouse gas emissions. In 
December 2020, the Canadian Federal Government unveiled its plan aimed to exceed their previous 2030 GHG-emissions 
reduction target of 30 per cent below 2005 levels to a new target of 32 to 40 per cent below 2005 levels with the ultimate 
goal of achieving net-zero GHG emissions by 2050. As part of this plan, the Federal Government narrowed the CFS scope to 
include only liquid fuels, which will not directly impact TC Energy. This plan also increased carbon pricing levels and released a 
complementary hydrogen strategy. Carbon prices increase by $15/tonne every year after 2022 to $170/tonne in 2030. While 
the scope of the CFS is limited to liquid fuels, there will be opportunities to generate credits for the gaseous fuel stream to 
incentivize emission reduction opportunities. We will continue to engage with Canadian policy makers and monitor and assess 
the extent of the impacts as more information is made available in early 2021. 

U.S. jurisdictions
• Federal: On August 6, 2020, the U.S. Senate passed the PHMSA reauthorization bill, the PIPES Act, which included methane 

regulations requiring, for example, pipeline owners/operators to implement methane LDAR programs, deploy advanced leak 
detection technology and incorporate LDAR surveys in inspection and maintenance plans. If the U.S. House of Representatives 
also supports the inclusion of these methane provisions, PHMSA will join the EPA as another federal regulator of GHG 
emissions, indicating the nation's increasing desire to combat climate change. The expected impact to our assets is still being 
evaluated

• Washington: In 2019, a law was enacted that committed the state electricity grid to becoming 80 per cent fossil fuel-free by 

2030 and 100 per cent by 2045. Ecology has begun rulemaking to further this goal. In Washington’s 2020 legislative session, a 
law was passed committing the state to becoming carbon-neutral by 2050 and strengthening intermediate reduction goals. 
Additionally, Ecology began rulemaking to implement the Governor’s December 2019 directive to strengthen and standardize 
the consideration of climate change risks, vulnerabilities and impacts in environmental assessments for major industrial and 
fossil fuel projects with significant environmental impacts. The impact to GTN's assets from regulations furthering these 
initiatives is still being evaluated 

• California: Our assets may be affected by the Governor of California's executive order, issued September 23, 2020, requiring all 
new cars and light trucks sold in California to be emission-free by 2035 and heavy and medium trucks to be emission-free by 
2045 since a significant number of vehicles in California are currently powered by natural gas. The significance of the impact

• Oregon: In March 2020, the Governor of Oregon issued an executive order to reduce and regulate GHGs by establishing annual 
reduction goals developing a new carbon cap and reduce program and enhancing clean fuel standards by January 1, 2022. 
Oregon has begun rulemaking to implement this executive order and we are assessing which of our GTN facilities in Oregon 
will be impacted. On July 31, 2020, a lawsuit was filed by a coalition of business and trade groups, including Oregon Business & 
Industry, challenging the executive order

• Michigan: The Michigan Department of Environment, Great Lakes, and Energy is currently evaluating potential ozone control 
strategies for the southeast Michigan ozone non-attainment area and the interaction of methane and ozone, which may lead 
to the development of laws and regulations that affect TC Energy through impacted ANR and Great Lakes facilities in the state

• New York: On August 14, 2020, New York’s Department of Environmental Conservation (NY DEC) released its proposed GHG 
reduction regulations, implementing the Climate Leadership and Community Protection Act, which directed the NY DEC to 
adopt GHG limits for all state emission sources. The proposed regulations require a reduction in GHGs equal to 60 per cent of 
the 1990 GHG emission levels by 2030 and to 15 per cent of the 1990 GHG emission levels by 2050. The proposed regulation 
does not include any compliance requirements and, as such, the impact to our assets cannot yet be measured.

Financial risks
We are exposed to market risk and counterparty credit risk and have strategies, policies and limits in place to manage the impact 
of these risks on our earnings, cash flows and, ultimately, shareholder value. 

Risk management strategies, policies and limits are designed to ensure our risks and related exposures are in line with our 
business objectives and risk tolerance. Market risk and counterparty credit risk are managed within limits that are established by 
our Board of Directors, implemented by senior management and monitored by our risk management and internal audit groups. 
Our Board of Directors' Audit Committee oversees how management monitors compliance with market risk and counterparty 
credit risk management policies and procedures and oversees management's review of the adequacy of the risk management 
framework.

Market risk
We construct and invest in energy infrastructure projects, purchase and sell commodities, issue short-term and long-term debt, 
including amounts in foreign currencies, and invest in foreign operations. Certain of these activities expose us to market risk 
from changes in commodity prices, foreign exchange rates and interest rates, which may affect our earnings and the value of our 
financial assets and liabilities. We assess contracts used to manage market risk to determine whether all, or a portion, meet the 
definition of a derivative.

Derivative contracts used to assist in managing exposure to market risk may include the following:
• forwards and futures contracts – agreements to purchase or sell a specific financial instrument or commodity at a specified 

price and date in the future 

• swaps – agreements between two parties to exchange streams of payments over time according to specified terms 
• options – agreements that convey the right, but not the obligation of the purchaser, to buy or sell a specific amount of a 

financial instrument or commodity at a fixed price, either at a fixed date or at any time within a specified period. 

Commodity price risk
The following strategies may be used to manage exposure to commodity price risk in our non-regulated businesses:
• in our natural gas marketing business, we enter into natural gas transportation and storage contracts as well as natural gas 

purchase and sale agreements. We manage our exposure on these contracts using financial instruments and hedging activities 
to offset market price volatility

• in our liquids marketing business, we enter into pipeline and storage terminal capacity contracts as well as crude oil purchase 
and sale agreements. We fix a portion of our exposure on these contracts by entering into financial instruments to manage 
variable price fluctuations that arise from physical liquids transactions

• in our power generation business, we manage our exposure to fluctuating commodity prices through long-term contracts and 

hedging activities including selling and purchasing power and natural gas in forward markets

• in our non-regulated natural gas storage business, our exposure to seasonal natural gas price spreads is managed with a 
portfolio of third-party storage capacity contracts and through offsetting purchases and sales of natural gas in forward 
markets to lock in future positive margins.

The following risks affect our company across all of our operations and are being continuously monitored.

Lower natural gas, crude oil and electricity prices could lead to reduced investment in the development, expansion and 
production of these commodities. A reduction in the supply of these commodities could negatively impact opportunities to 
expand our asset base and re-contract with our shippers and customers as their contractual agreements expire. 

TC Energy Management's discussion and analysis 2020   |  95

Climate change also presents a potential financial impact to commodity prices and volumes. Our exposure to climate change risk 
and resulting policy changes is managed through our business model which is based on a long-term, low-risk strategy whereby 
the majority of our earnings are underpinned by regulated cost-of-service arrangements and long-term contracts. In addition, 
scenario planning against several demand outlooks and monitoring of key signposts is also considered as part of our long-term 
corporate strategic planning process. 

Interest rate risk
We utilize short-term and long-term debt to finance our operations which exposes us to interest rate risk. We typically pay fixed 
rates of interest on our long-term debt and floating rates on our commercial paper programs and amounts drawn on our credit 
facilities. A small portion of our long-term debt bears interest at floating rates. In addition, we are exposed to interest rate risk 
on financial instruments and contractual obligations containing variable interest rate components. We actively manage our 
interest rate risk using interest rate derivatives.

Many of our financial instruments and contractual obligations with variable rate components reference LIBOR, of which certain 
rate settings may cease to be published at the end of 2021 with full cessation expected by mid-2023. We continue to monitor 
developments and are preparing to address any necessary system and contractual changes while assessing the adoption of the 
standard market proposed reference rates. This includes identifying and analyzing existing agreements to determine the effect 
of reference rate reform on our consolidated financial statements. 

Foreign exchange risk
We generate revenues and incur expenses and capital expenditures that are denominated in currencies other than Canadian 
dollars. As a result, our earnings and cash flows are exposed to currency fluctuations.

A significant portion of our businesses generate earnings in U.S. dollars, but since we report our financial results in Canadian 
dollars, changes in the value of the U.S. dollar against the Canadian dollar can affect our net income. As our U.S. dollar-
denominated operations continue to grow, this exposure increases. A portion of this risk is offset by interest expense on 
U.S. dollar-denominated debt. The balance of the exposure is actively managed on a rolling two-year basis using foreign 
exchange derivatives, however, the natural exposure beyond that period remains.

Average exchange rate – U.S. to Canadian dollars

We hedge a portion of our net investment in foreign operations (on an after-tax basis) with U.S. dollar-denominated debt,     
cross-currency swaps and foreign exchange options.

A small portion of our Mexico Natural Gas Pipelines monetary assets and liabilities are peso-denominated, while the functional 
currency for our Mexico operations is U.S. dollars. These peso-denominated balances are revalued to U.S. dollars and, as a result, 
changes in the value of the Mexican peso against the U.S. dollar can affect our net income. This exposure is managed using 
foreign exchange derivatives.

Counterparty credit risk
We have exposure to counterparty credit risk in a number of areas including:
• cash and cash equivalents
• accounts receivable
• available-for-sale assets
• the fair value of derivative assets
• loans receivable.

The sustained impact of the COVID-19 pandemic and related global energy demand and supply disruption continues to 
contribute to market uncertainty impacting a number of our customers. While the majority of our credit exposure is to large 
creditworthy entities, we have increased our monitoring of and communication with those counterparties experiencing greater 
financial pressures due to recent market events. Although counterparty credit risk has heightened and the long-term impacts of 
COVID-19 and related disruptions on our customers are difficult to predict, we are not expecting a material negative impact to 
our 2021 earnings or cash flows as a result of this increased risk. 

At times, our counterparties may endure financial challenges resulting from commodity price and market volatility, economic 
instability and political or regulatory changes. In addition to actively monitoring these situations, there are a number of factors 
that reduce our counterparty credit risk exposure in the event of default, including:
• contractual rights and remedies together with the utilization of contractually-based financial assurances
• current regulatory frameworks governing certain of our operations
• the competitive position of our assets and the demand for our services
• potential recovery of unpaid amounts through bankruptcy and similar proceedings.

We review financial assets carried at amortized cost for impairment using the lifetime expected loss of the financial asset at 
initial recognition and throughout the life of the financial asset. We use historical credit loss and recovery data, adjusted for our 
judgment regarding current economic and credit conditions, along with supportable forecasts to determine any impairment, 
which is recognized in Plant operating costs and other. At December 31, 2020 and 2019, we had no significant credit losses, no 
significant credit risk concentrations and no significant amounts past due or impaired. 

We have significant credit and performance exposure to financial institutions because they hold cash deposits and provide 
committed credit lines and letters of credit that help manage our exposure to counterparties and provide liquidity in commodity, 
foreign exchange and interest rate derivative markets. 

Liquidity risk
Liquidity risk is the risk that we will not be able to meet our financial obligations as they come due. We manage our liquidity by 
continuously forecasting our cash flows and ensuring we have adequate cash balances, cash flows from operations, committed 
and demand credit facilities and access to capital markets to meet our operating, financing and capital expenditure obligations 
under both normal and stressed economic conditions. There have been periods of heightened global market volatility and 
reduced liquidity during 2020 but we have taken steps to further strengthen our financial condition and mitigate our exposure to 
these risks. Refer to the Financial condition section for more information about our liquidity.

Legal proceedings
Legal proceedings, arbitrations and actions are part of doing business. While we cannot predict the final outcomes of 
proceedings and actions with certainty, management does not expect any current or potential legal proceeding or action to 
have a material impact on our consolidated financial position or results of operations.

CONTROLS AND PROCEDURES
We meet Canadian and U.S. regulatory requirements for disclosure controls and procedures, internal control over financial 
reporting and related CEO and CFO certifications.

Disclosure controls and procedures
Under the supervision and with the participation of management, including our President and CEO and our CFO, we carried out 
quarterly evaluations of the effectiveness of our disclosure controls and procedures, including for the year ended               
December 31, 2020, as required by the Canadian securities regulatory authorities and by the SEC. Based on this evaluation, our 
President and CEO and our CFO have concluded that the disclosure controls and procedures are effective in that they are 
designed to ensure that the information we are required to disclose in reports we file with or send to securities regulatory 
authorities is recorded, processed, summarized and reported accurately within the time periods specified under Canadian and 
U.S. securities laws.

Management’s annual report on internal control over financial reporting
We are responsible for establishing and maintaining adequate internal control over financial reporting, which is a process 
designed by, or under the supervision of, our President and CEO and our CFO, and effected by our Board of Directors, 
management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the 
preparation of financial statements for external purposes in accordance with GAAP.

Under the supervision and with the participation of management, including our President and CEO and our CFO, an evaluation of 
the effectiveness of the internal control over financial reporting was conducted as of December 31, 2020, based on the criteria 
described in “Internal Control – Integrated Framework” issued in 2013 by the Committee of Sponsoring Organizations of the 
Treadway Commission. Based on this assessment, management determined that, as of December 31, 2020, the internal control 
over financial reporting was effective. 

Our internal control over financial reporting as of December 31, 2020 has been audited by KPMG LLP, an independent registered 
public accounting firm, as stated in their attestation report which is included in this document. 

CEO and CFO certifications
Our President and CEO and our CFO have attested to the quality of the public disclosure in our fiscal 2020 reports filed with 
Canadian securities regulators and the SEC and have filed certifications with them.

Changes in internal control over financial reporting
There were no changes during the year covered by this annual report that had or are reasonably likely to have a material impact 
on our internal control over financial reporting.

CRITICAL ACCOUNTING ESTIMATES
When we prepare financial statements that conform with GAAP, we are required to make estimates and assumptions that affect 
the timing and amounts we record for our assets, liabilities, revenues and expenses because these items may be affected by 
future events. We base the estimates and assumptions on the most current information available, using our best judgment. We 
also regularly assess the assets and liabilities themselves.

The following accounting estimates require us to make significant assumptions based on factors that are either subjective or 
highly uncertain when preparing our financial statements and changes in these assumptions could have a material impact on the 
financial statements. Our accounting policies disclose the critical accounting estimates we make when preparing our financial 
statements. 

Impairment of long-lived assets and goodwill
We review long-lived assets, such as plant, property and equipment, equity investments, goodwill and capital projects in 
development, for impairment whenever events or changes in circumstances lead us to believe we might not be able to recover 
an asset's carrying value. Factors we consider in our assessment of the recoverability of long-lived assets include, but are not 
limited to, macroeconomic conditions, changes in the industries and markets in which we operate, our ability to renew 
contracts, and the financial performance and prospects of our assets. If the total of the undiscounted future cash flows that we 
estimate for an asset within Property, plant and equipment, or the estimated selling price of any long-lived asset is less than its 
carrying value, we consider its fair value to be less than its carrying value and record an impairment loss to recognize this. For 
goodwill, if the fair value of the reporting unit determined using discounted cash flows is less than its carrying value, including 
goodwill, we consider it to be impaired.

In 2020 and 2019, no impairments were recorded.

In 2018, the following impairments were recorded:
• a $722 million pre-tax impairment of the carrying value of Bison's plant, property and equipment ($140 million after tax and 

net of non-controlling interests)

• a $79 million pre-tax impairment of the carrying value of Tuscarora's goodwill ($15 million after tax and net of non-controlling 

interests).

Long-lived assets

Bison 
In December 2018, we evaluated our investment in the Bison natural gas pipeline for impairment in connection with the 
termination of certain customer transportation agreements. With the loss of these contracted future cash flows, and the 
persistence of unfavourable market conditions which have inhibited system flows on the pipeline, we determined that the 
asset’s remaining carrying value was no longer recoverable and recognized a non-cash impairment charge of $722 million in the 
U.S. Natural Gas Pipelines segment. Our share of the impairment charge, after tax and net of non-controlling interests, was            
$140 million.

Goodwill
We test goodwill for impairment annually or more frequently if events or changes in circumstances lead us to believe it might be 
impaired. We can initially assess qualitative factors which include, but are not limited to, macroeconomic conditions, industry 
and market considerations, current valuation multiples and discount rates, cost factors, historical and forecasted financial 
results, or events specific to that reporting unit. If we conclude that it is not more likely than not that the fair value of the 
reporting unit is greater than its carrying value, we will then perform a quantitative goodwill impairment test. We can elect to 
proceed directly to the quantitative goodwill impairment test for any reporting unit. If the quantitative goodwill impairment test 
is performed, we compare the fair value of the reporting unit to its carrying value, including its goodwill. If the carrying value of 
a reporting unit exceeds its fair value, goodwill impairment is measured at the amount by which the reporting unit’s carrying 
value exceeds its fair value. 

TC Energy Management's discussion and analysis 2020   |  99

When a portion of a reporting unit that constitutes a business is disposed, goodwill associated with that business is included in 
the carrying amount of the business in determining the gain or loss on disposal. The amount of goodwill disposed is determined 
based on the relative fair values of the business to be disposed and the portion of the reporting unit that will be retained. In 
August 2019, we completed the sale of certain Columbia Midstream assets to a third party. As these assets constituted a business 
within the Columbia reporting unit, $595 million of Columbia's goodwill allocated to these assets was released and netted in the 
gain on sale. 

We determine the fair value of a reporting unit based on our projections of future cash flows, which involves making estimates 
and assumptions about transportation rates, market supply and demand, growth opportunities, output levels, competition from 
other companies, operating costs, regulatory changes, discount rates and earnings and other multiples. 

As part of the annual goodwill impairment assessment, we evaluated qualitative factors impacting the fair value of the reporting 
units. It was determined that it was more likely than not that the fair value of the reporting units exceeded their carrying 
amounts, including goodwill, and therefore, goodwill was not impaired.

Tuscarora
In fourth quarter 2018, we determined that the fair value of Tuscarora did not exceed its carrying value, including goodwill, and 
recorded a goodwill impairment charge of $79 million within the U.S. Natural Gas Pipelines segment. Our share of the goodwill 
impairment charge, after tax and net of non-controlling interests, was $15 million. Our share of the remaining goodwill balance 
related to Tuscarora, net of non-controlling interests, was US$6 million at December 31, 2020 (2019 – US$6 million). 

FINANCIAL INSTRUMENTS
We use derivative instruments to reduce volatility associated with fluctuations in commodity prices, interest rates and foreign 
exchange rates. Derivative instruments, including those that qualify and are designated for hedge accounting treatment, are 
recorded at fair value. 

The majority of derivative instruments that are not designated or do not qualify for hedge accounting treatment have been 
entered into as economic hedges to manage our exposure to market risk and are classified as held for trading. Changes in the fair 
value of held-for-trading derivative instruments are recorded in net income in the period of change. This may expose us to 
increased variability in reported operating results since the fair value of the held-for-trading derivative instruments can fluctuate 
significantly from period to period.

The recognition of gains and losses on derivatives for Canadian natural gas regulated pipeline exposures is determined through 
the regulatory process. Gains and losses arising from changes in the fair value of derivatives accounted for as part of RRA, 
including those that qualify for hedge accounting treatment, are expected to be recovered or refunded through the tolls 
charged by us. As a result, these gains and losses are deferred as regulatory assets or regulatory liabilities and are refunded to or 
collected from the ratepayers in subsequent years when the derivative settles.

Factors affecting quarterly financial information by business segment
Quarter-over-quarter revenues and net income fluctuate for reasons that vary across our business segments.

In our Canadian Natural Gas Pipelines, U.S. Natural Gas Pipelines and Mexico Natural Gas Pipelines segments, except for seasonal 
fluctuations in short-term throughput volumes on U.S. pipelines, quarter-over-quarter revenues and net income generally 
remain relatively stable during any fiscal year. Over the long term, however, they fluctuate because of:
• regulators' decisions
• negotiated settlements with shippers
• newly constructed assets being placed in service
• acquisitions and divestitures
• developments outside of the normal course of operations.

In Liquids Pipelines, annual revenues and net income are based on contracted and uncommitted spot transportation as well as 
liquids marketing activities. Quarter-over-quarter revenues and net income are affected by:
• regulatory decisions
• newly constructed assets being placed in service
• acquisitions and divestitures
• demand for uncontracted transportation services
• liquids marketing activities and commodity prices
• developments outside of the normal course of operations
• certain fair value adjustments.

• newly constructed assets being placed in service
• acquisitions and divestitures
• market prices for natural gas and power
• capacity prices and payments
• planned and unplanned plant outages
• developments outside of the normal course of operations
• certain fair value adjustments.

Factors affecting financial information by quarter
We calculate comparable measures by adjusting certain GAAP and non-GAAP measures for specific items we believe are 
significant but not reflective of our underlying operations in the period. 

Comparable earnings exclude the unrealized gains and losses from changes in the fair value of certain derivatives used to reduce 
our exposure to certain financial and commodity price risks. These derivatives generally provide effective economic hedges, but 
do not meet the criteria for hedge accounting. As a result, the changes in fair value are recorded in net income. As these 
amounts do not accurately reflect the gains and losses that will be realized at settlement, we do not consider them part of our 
underlying operations. We also exclude the unrealized foreign exchange gains and losses on the Loan receivable from affiliate as 
well as the corresponding proportionate share of Sur de Texas foreign exchange gains and losses, as these amounts do not 
accurately reflect the gains and losses that will be realized at settlement. These amounts offset within each reporting period, 
resulting in no impact on net income. 

In fourth quarter 2020, comparable earnings also excluded:
• an income tax valuation allowance release of $18 million related to certain prior years' U.S. tax losses resulting from our 

reassessment of deferred tax assets that are more likely than not to be realized

• an additional $18 million income tax recovery related to state income taxes on the sale of certain Columbia Midstream assets in 

2019

• an incremental after-tax loss of $81 million for the three months ended December 31, 2020 related to the sale of our Ontario 

natural gas-fired power plants.

In third quarter 2020, comparable earnings also excluded:
• an incremental after-tax loss of $45 million related to the sale of the Ontario natural gas-fired power plants
• a $6 million reduction in the after-tax gain related to the sale of a 65 per cent equity interest in Coastal GasLink LP.

In second quarter 2020, comparable earnings also excluded:
• an after-tax gain for $408 million related to the sale of a 65 per cent equity interest in Coastal GasLink LP
• an incremental after-tax loss of $80 million related to the sale of the Ontario natural gas-fired power plants.

In first quarter 2020, comparable earnings also excluded:
• an income tax valuation allowance release of $281 million following our reassessment of deferred tax assets that are deemed 

more likely than not to be realized as a result of our decision to proceed with the Keystone XL project

• an incremental after-tax loss of $77 million related to the Ontario natural gas-fired power plant assets held for sale.

In fourth quarter 2019, comparable earnings also excluded:
• an income tax valuation allowance release of $195 million related to certain prior years' U.S. tax losses resulting from our 

reassessment of deferred tax assets that are more likely than not to be realized

• an incremental after-tax loss of $61 million related to the Ontario natural gas-fired power plant assets held for sale
• an additional $19 million income tax expense related to state income taxes on the sale of certain Columbia Midstream assets.

In third quarter 2019, comparable earnings also excluded:
• an after-tax loss of $133 million related to the Ontario natural gas-fired power plant assets held for sale
• an after-tax loss of $133 million related to the sale of certain Columbia Midstream assets
• an after-tax gain of $115 million related to the partial sale of Northern Courier.

In second quarter 2019, comparable earnings also excluded:
• an after-tax gain of $54 million related to the sale of our Coolidge generating station 
• a deferred tax benefit of $32 million related to the impact of an Alberta corporate income tax rate reduction on our Canadian 

businesses not subject to RRA

• an after-tax gain of $6 million related to the remainder of our U.S. Northeast power marketing contracts.

In first quarter 2019, comparable earnings also excluded:
• an after-tax loss of $12 million related to our U.S. Northeast power marketing contracts.

Comparable EBITDA – 2020 versus 2019
Comparable EBITDA increased by $8 million for the three months ended December 31, 2020 compared to the same period in 
2019 primarily due to the net effect of the following:
• increased earnings from U.S. Natural Gas Pipelines mainly attributable to lower operating costs
• higher comparable EBITDA from Canadian Natural Gas Pipelines due to the impact of increased rate-base earnings,               

flow-through depreciation from additional facilities placed in service as well as higher financial charges on the NGTL System 
plus Coastal GasLink development fee revenue recognized in 2020, partially offset by a decrease in flow-through income taxes 
on the NGTL System and Canadian Mainline

• lower contribution from Liquids Pipelines primarily attributable to reduced margins from our liquids marketing activities
• decreased contribution from Power and Storage primarily due to the net impact of lower Bruce Power earnings in 2020 

reflecting the commencement of the Unit 6 MCR program on January 17, 2020, partially offset by fewer outage days on the 
remaining units, the sale of our Ontario natural gas-fired power plants on April 29, 2020, and improved results from our 
Alberta cogeneration plants 

• foreign exchange impact of a weaker U.S. dollar on the Canadian dollar equivalent earnings from our U.S. dollar-denominated 

operations.

Due to the flow-through treatment of certain expenses including income taxes, financial charges and depreciation on our 
Canadian rate-regulated pipelines, changes in these items impact our comparable EBITDA despite having no significant effect on 
net income.

Comparable earnings – 2020 versus 2019
Comparable earnings increased by $110 million or $0.12 per common share for the three months ended December 31, 2020 
compared to the same period in 2019 and was primarily the net effect of:
• changes in comparable EBITDA described above
• a decrease in income tax expense mainly attributable to lower flow-through income taxes on Canadian rate-regulated 

pipelines and higher foreign tax rate differentials

• a decrease in interest expense primarily due to higher capitalized interest related to Keystone XL, partially offset by the 

completion of Napanee construction in first quarter 2020 and the application of equity accounting to our Coastal GasLink LP 
investment upon the sale of a 65 per cent interest in the project in May 2020. The reduction in interest expense was also a 
result of lower interest rates on short-term borrowings and the foreign exchange impact of a weaker U.S. dollar on translation 
of U.S. dollar-denominated interest

• higher Interest income and other primarily related to derivatives used to manage our net exposure to foreign exchange rate 

fluctuations on U.S. dollar denominated income

• lower AFUDC primarily due to NGTL System expansion projects placed in service and the suspension of recording AFUDC on the 

Tula project, partially offset by Columbia Gas growth projects

• higher depreciation in Canadian Natural Gas Pipelines reflecting new assets placed in service as discussed above, partially 

offset by lower depreciation in Power and Storage mainly due to a 2019 reassessment of the useful life of certain components 
at our Alberta cogeneration plants.

Comparable earnings per share reflected the dilutive impact of common shares issued under our DRP in 2019.

Highlights by business segment
Canadian Natural Gas Pipelines
Canadian Natural Gas Pipelines segmented earnings increased by $29 million for the three months ended December 31, 2020 
compared to the same period in 2019. 

Net income for the NGTL System increased by $17 million for the three months ended December 31, 2020 compared to the same 
period in 2019 mainly due to a higher average investment base resulting from continued system expansions. On August 17, 2020, 
the CER approved the NGTL System's 2020-2024 Revenue Requirement Settlement Application. This settlement, which is 
effective from January 1, 2020 to December 31, 2024, includes an ROE of 10.1 per cent on 40 per cent deemed equity, provides 
the NGTL System the opportunity to increase depreciation rates if tolls fall below pre-determined levels and includes an incentive 
mechanism for certain operating costs where variances from projected amounts are shared between the NGTL System and its 
customers. It also includes a mechanism to review the settlement should tolls exceed a pre-determined level, without affecting 
the equity return. The NGTL System’s 2019 results reflected the 2018-2019 Revenue Requirement Settlement that expired on 
December 31, 2019 which included an ROE of 10.1 per cent on 40 per cent deemed common equity, a mechanism for sharing 
variances above and below a fixed annual OM&A amount and flow-through treatment of all other costs.

Net income for the Canadian Mainline decreased by $2 million for the three months ended December 31, 2020 compared to the 
same period in 2019.

Comparable EBITDA for Canadian Natural Gas Pipelines increased by $64 million for the three months ended December 31, 2020 
compared to the same period in 2019 due to the net effect of:
• increased rate-base earnings and flow-through depreciation on the NGTL System due to additional facilities placed in service 

as well as higher flow-through financial charges 

• Coastal GasLink development fee revenue recognized in 2020
• lower flow-through income taxes on the NGTL System and the Canadian Mainline.

Depreciation and amortization increased by $35 million for the three months ended December 31, 2020 compared to the same 
period in 2019 mainly due to additional NGTL System facilities placed in service in 2020.

U.S. Natural Gas Pipelines
U.S. Natural Gas Pipelines segmented earnings and comparable EBIT increased by $64 million for the three months ended 
December 31, 2020 compared to the same period in 2019. A weaker U.S. dollar in fourth quarter 2020 had a negative impact on 
the Canadian dollar equivalent segmented earnings from our U.S. operations compared to the same period in 2019.

108  |   TC Energy Management's discussion and analysis 2020

U.S. Natural Gas Pipelines comparable EBITDA increased by US$58 million for the three months ended December 31, 2020 
compared to the same period in 2019 mainly due to lower operating costs across a number of pipelines.

Depreciation and amortization increased by US$2 million for the three months ended December 31, 2020 compared to the same 
period in 2019 mainly due to new projects placed in service. 

Mexico Natural Gas Pipelines
Mexico Natural Gas Pipelines comparable EBIT and segmented earnings increased by $1 million for the three months ended 
December 31, 2020 compared to the same period in 2019. A weaker U.S. dollar in fourth quarter 2020 had a negative impact on 
the Canadian dollar equivalent segmented earnings from our Mexico operations compared to the same period in 2019.

Comparable EBITDA for Mexico Natural Gas Pipelines increased by US$3 million for the three months ended December 31, 2020 
compared to the same period in 2019 mainly due to increased revenues.

Depreciation and amortization for the three months ended December 31, 2020 was consistent with the same period in 2019.

Liquids Pipelines
Liquids Pipelines segmented earnings decreased by $55 million for the three months ended December 31, 2020 compared to the 
same period in 2019 and included unrealized losses from changes in the fair value of derivatives related to our liquids marketing 
business which have been excluded from our calculation of comparable EBIT and comparable earnings in both periods. In 
addition, a weaker U.S. dollar in fourth quarter 2020 had a negative impact on the Canadian dollar equivalent segmented 
earnings compared to the same period in 2019.

Comparable EBITDA for Liquids Pipelines decreased by $64 million for the three months ended December 31, 2020 compared to 
the same period in 2019. This was primarily due to lower contributions from liquids marketing activities mainly attributable to 
lower margins.

Depreciation and amortization for the three months ended December 31, 2020 was comparable to the same period in 2019.

Power and Storage
Power and Storage segmented earnings decreased by $59 million for the three months ended December 31, 2020 compared to 
the same period in 2019 and included the following specific items which have been excluded from comparable EBIT:
• a pre-tax loss of $93 million for the three months ended December 31, 2020 (pre-tax loss of $77 million for the three months 

ended December 31, 2019) related to the sale of our Ontario natural gas-fired power plants 

• unrealized losses from changes in the fair value of derivatives used to reduce our exposure to certain commodity price risks.

Comparable EBITDA for Power and Storage decreased by $49 million for the three months ended December 31, 2020 compared 
to the same period in 2019 primarily due to the net effect of:
• the planned removal from service of Bruce Power Unit 6 on January 17, 2020 for its MCR program, partially offset by fewer 

planned outage days on the remaining units

• lower Canadian Power earnings largely as a result of the sale of our Ontario natural gas-fired power plants on April 29, 2020, 

partially offset by improved results from our Alberta cogeneration plants 

• higher contributions from Natural Gas Storage and other primarily due to the acquisition of the remaining 50 per cent 

ownership of TC Turbines on November 13, 2020.

Depreciation and amortization decreased by $10 million for the three months ended December 31, 2020 primarily due to lower 
depreciation at our Alberta cogeneration plants due to a reassessment of the useful life of certain components performed in 
2019.

Corporate
Corporate segmented losses increased by $81 million for the three months ended December 31, 2020 compared to the same 
period in 2019 and included foreign exchange losses on our proportionate share of peso-denominated inter-affiliate loans to the 
Sur de Texas joint venture from its partners. These amounts are recorded in Income from equity investments and have been 
excluded from our calculation of comparable EBITDA and EBIT as they are fully offset by corresponding foreign exchange gains on 
the inter-affiliate loan receivable included in Interest income and other.

Comparable EBITDA for Corporate decreased by $8 million for the three months ended December 31, 2020 compared to the same 
period in 2019 primarily due to increased corporate expenses.

Management's Report on Internal Control over Financial Reporting

The consolidated financial statements and Management's Discussion and Analysis (MD&A) included in this Annual Report are the 
responsibility of the management of TC Energy Corporation (TC Energy or the Company) and have been approved by the Board 
of Directors of the Company. The consolidated financial statements have been prepared by management in accordance with 
United States generally accepted accounting principles (GAAP) and include amounts that are based on estimates and judgments. 
The MD&A is based on the Company's financial results. It compares the Company's financial and operating performance in 2020 
to that in 2019, and highlights significant changes between 2019 and 2018. The MD&A should be read in conjunction with the 
consolidated financial statements and accompanying notes. Financial information contained elsewhere in this Annual Report is 
consistent with the consolidated financial statements.

Management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. 
Management has designed and maintains a system of internal control over financial reporting, including a program of internal 
audits to carry out its responsibility. Management believes these controls provide reasonable assurance that financial records are 
reliable and form a proper basis for the preparation of financial statements. The internal control over financial reporting includes 
management's communication to employees of policies that govern ethical business conduct.

Under the supervision and with the participation of the President and Chief Executive Officer and the Chief Financial Officer, 
management conducted an evaluation of the effectiveness of its internal control over financial reporting based on the 
framework in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the 
Treadway Commission (COSO). Management concluded, based on its evaluation, that internal control over financial reporting 
was effective as of December 31, 2020, to provide reasonable assurance regarding the reliability of financial reporting and the 
preparation of financial statements for external reporting purposes.

The Board of Directors is responsible for reviewing and approving the financial statements and MD&A and ensuring that 
management fulfills its responsibilities for financial reporting and internal control. The Board of Directors carries out these 
responsibilities primarily through the Audit Committee, which consists of independent, non-management directors. The Audit 
Committee meets with management at least five times a year and meets independently with internal and external auditors and 
as a group to review any significant accounting, internal control and auditing matters in accordance with the terms of the 
Charter of the Audit Committee, which is set out in the Annual Information Form. The Audit Committee's responsibilities include 
overseeing management's performance in carrying out its financial reporting responsibilities and reviewing the Annual Report, 
including the consolidated financial statements and MD&A, before these documents are submitted to the Board of Directors for 
approval. The internal and independent external auditors have access to the Audit Committee without the requirement to obtain 
prior management approval.

The Audit Committee approves the terms of engagement of the independent external auditors and reviews the annual audit 
plan, the Auditors' Report and the results of the audit. It also recommends to the Board of Directors the firm of external auditors 
to be appointed by the shareholders.

The shareholders have appointed KPMG LLP as independent external auditors to express an opinion as to whether the 
consolidated financial statements present fairly, in all material respects, the Company's consolidated financial position, results 
of operations and cash flows in accordance with GAAP. The reports of KPMG LLP outline the scope of its examinations and its 
opinions on the consolidated financial statements and the effectiveness of the Company's internal control over financial 
reporting.

TC Energy Consolidated Financial Statements 2020   |  111

 
 
 
Report of Independent Registered Public Accounting Firm

To the Shareholders of TC Energy Corporation

Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheets of TC Energy Corporation (the Company) as of               
December 31, 2020 and 2019, the related consolidated statements of income, comprehensive income, cash flows, and equity for 
each of the years in the three-year period ended December 31, 2020, and the related notes (collectively, the consolidated 
financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial 
position of the Company as of December 31, 2020, and 2019, and the results of its operations and its cash flows for each of the 
years in the three‑year period ended December 31, 2020, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company’s internal control over financial reporting as of December 31, 2020, based on criteria established in 
Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway 
Commission, and our report dated February 17, 2021 expressed an unqualified opinion on the effectiveness of the Company’s 
internal control over financial reporting.

Basis for Opinion
These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an 
opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the 
PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and 
the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, 
whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the 
consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such 
procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial 
statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, 
as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a 
reasonable basis for our opinion.

Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial 
statements that was communicated or required to be communicated to the Audit Committee and that: (1) relates to accounts or 
disclosures that are material to the consolidated financial statements; and (2) involved our especially challenging, subjective or 
complex judgment. The communication of a critical audit matter does not alter in any way our opinion on the consolidated 
financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate 
opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Qualitative goodwill impairment indicators 
As discussed in Note 12 to the consolidated financial statements, the goodwill balance as of December 31, 2020 was               
$12,679 million. The Company assesses goodwill for impairment testing annually or more frequently if events or changes in 
circumstances indicate that the carrying value of a reporting unit might be impaired. In the current year, the Company only 
performed qualitative assessments to determine whether events or changes in circumstances indicate that goodwill might be 
impaired. These qualitative assessments were performed as of December 31, 2020.

112  |   TC Energy Consolidated Financial Statements 2020 

We identified the evaluation of qualitative goodwill impairment indicators, or qualitative factors, as a critical audit matter. The 
assessment of the potential impact that these qualitative factors have on a reporting unit's fair value required the application of 
subjective auditor judgment. Qualitative factors included macroeconomic conditions, industry and market considerations, 
current valuation multiples and discount rates, cost factors, historical and forecasted financial results and events specific to the 
reporting units, which required a higher degree of auditor judgment to evaluate. These qualitative factors could have had a 
significant effect on the Company's qualitative assessment and the potential for the need to perform a quantitative goodwill 
impairment test.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested 
the operating effectiveness of certain internal controls related to the Company's goodwill impairment assessment process, 
including controls related to the assessment of potential qualitative factors. We evaluated the Company's assessment of 
identified event-specific changes against our knowledge of event-specific changes obtained through other audit procedures. We 
evaluated information from analyst reports in the energy and utility industries, including global energy consumption forecasts 
and natural gas production forecasts, which were compared to geopolitical and market considerations used by the Company. We 
compared current valuation multiples and discount rates, cost factors, historical and forecasted financial results of the reporting 
units, including the impact of newly approved growth projects to assumptions used in quantitative goodwill impairment tests 
performed in previous periods. In addition, we involved a valuation professional with specialized skills and knowledge, who 
assisted in:
• evaluating the Company’s determination of valuation multiples by comparing to independently observed recent market 

transactions of comparable assets and using publicly available market data for comparable entities;

• evaluating the discount rates used by management in the evaluation, by comparing them against a discount rate range that 

was independently developed using publicly available market data for comparable entities.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of TC Energy Corporation

Opinion on Internal Control Over Financial Reporting
We have audited TC Energy Corporation’s (the Company) internal control over financial reporting as of December 31, 2020, 
based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring 
Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal 
control over financial reporting as of December 31, 2020, based on criteria established in Internal Control – Integrated 
Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the consolidated balance sheets of the Company as of December 31, 2020 and 2019, the related consolidated 
statements of income, comprehensive income, cash flows, and equity for each of the years in the three-year period ended 
December 31, 2020, and the related notes (collectively, the consolidated financial statements), and our report dated     
February 17, 2021 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its 
assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report 
on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over 
financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be 
independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and 
regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all 
material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control 
over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating 
effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we 
considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures 
that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit 
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and 
expenditures of the company are being made only in accordance with authorizations of management and directors of the 
company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or 
disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Notes to consolidated financial statements

1.  DESCRIPTION OF TC ENERGY'S BUSINESS

TC Energy Corporation (TC Energy or the Company) is a leading North American energy infrastructure company which operates in 
five business segments: Canadian Natural Gas Pipelines, U.S. Natural Gas Pipelines, Mexico Natural Gas Pipelines, Liquids Pipelines 
and Power and Storage. These segments offer different products and services, including certain natural gas, crude oil and 
electricity marketing and storage services. The Company also has a Corporate segment, consisting of corporate and 
administrative functions that provide governance, financing and other support to the Company's business segments.

Canadian Natural Gas Pipelines
The Canadian Natural Gas Pipelines segment primarily consists of the Company's investments in 40,707 km (25,294 miles) of 
regulated natural gas pipelines.

U.S. Natural Gas Pipelines
The U.S. Natural Gas Pipelines segment primarily consists of the Company's investments in 50,211 km (31,199 miles) of regulated 
natural gas pipelines, 535 Bcf of regulated natural gas storage facilities and other assets, owned directly and through the 
Company's investment in TC PipeLines, LP. 

Mexico Natural Gas Pipelines
The Mexico Natural Gas Pipelines segment primarily consists of the Company's investments in 2,503 km (1,554 miles) of 
regulated natural gas pipelines.

Liquids Pipelines
The Liquids Pipelines segment primarily consists of the Company's investments in 4,946 km (3,075 miles) of crude oil pipeline 
systems which connect Alberta and U.S. crude oil supplies to U.S. refining markets in Illinois, Oklahoma and Texas.

Power and Storage
The Power and Storage segment primarily consists of the Company's investments in seven power generation facilities and 118 Bcf 
of non-regulated natural gas storage facilities. These assets are located in Alberta, Ontario, Québec and New Brunswick.

2.  ACCOUNTING POLICIES

The Company's consolidated financial statements have been prepared by management in accordance with U.S. generally 
accepted accounting principles. Amounts are stated in Canadian dollars unless otherwise indicated.

Basis of Presentation
These consolidated financial statements include the accounts of TC Energy and its subsidiaries. The Company consolidates 
variable interest entities (VIEs) for which it is considered to be the primary beneficiary as well as voting interest entities in which 
it has a controlling financial interest. To the extent there are interests owned by other parties, these interests are included in 
non-controlling interests, although certain non-controlling interests with redemption features are presented in mezzanine 
equity. TC Energy uses the equity method of accounting for joint ventures in which the Company is able to exercise joint control 
and for investments in which the Company is able to exercise significant influence. TC Energy records its proportionate share of 
undivided interests in certain assets. Certain prior year amounts have been reclassified to conform to current year presentation.

Use of Estimates and Judgments
In preparing these consolidated financial statements, TC Energy is required to make estimates and assumptions that affect both 
the amount and timing of recording assets, liabilities, revenues and expenses since the determination of these items may be 
dependent on future events. The Company uses the most current information available and exercises careful judgment in 
making these estimates and assumptions.

120  |   TC Energy Consolidated Financial Statements 2020

Certain estimates and judgments have a material impact where the assumptions underlying these accounting estimates relate to 
matters that are highly uncertain at the time the estimate or judgment is made or are subjective. These estimates and judgments 
include, but are not limited to:
• recoverability of plant, property and equipment (Notes 7 and 30) and development costs (Notes 13 and 30)
• fair value of reporting units that contain goodwill (Notes 12 and 27) and
• fair value of assets and liabilities acquired in a business combination (Note 27).

Some of the estimates and judgments the Company has to make have a material impact on the consolidated financial 
statements, but do not involve significant subjectivity or uncertainty. These estimates and judgments include, but are not 
limited to: 
• depreciation rates of plant, property and equipment (Note 7)
• determining whether a contract contains a lease (Note 8) 
• fair value of equity investments (Note 9)
• carrying value of regulatory assets and liabilities (Note 11)
• carrying value of asset retirement obligations (Note 16)
• provisions for income taxes, including valuation allowances and releases (Note 17)
• assumptions used to measure retirement and other post-retirement benefit obligations (Note 24) 
• fair value of financial instruments (Note 25) and 
• provisions for commitments, contingencies and guarantees (Note 28). 

Actual results could differ from these estimates.

Regulation
Certain Canadian, U.S. and Mexico natural gas pipeline and storage assets are regulated with respect to construction, operations 
and the determination of tolls. In Canada, regulated natural gas pipelines and liquids pipelines are subject to the authority of the 
Canada Energy Regulator (CER), formerly the National Energy Board (NEB), the Alberta Energy Regulator or the B.C. Oil and Gas 
Commission. In the U.S., regulated natural gas pipelines, liquids pipelines and regulated natural gas storage assets are subject to 
the authority of the Federal Energy Regulatory Commission (FERC). In Mexico, regulated natural gas pipelines are subject to the 
authority of the Energy Regulatory Commission (CRE). Rate-regulated accounting (RRA) standards may impact the timing of the 
recognition of certain revenues and expenses in TC Energy's rate-regulated businesses which may differ from that otherwise 
recognized in non-rate-regulated businesses to reflect the economic impact of the regulators' decisions regarding revenues and 
tolls. Regulatory assets represent costs that are expected to be recovered in customer rates in future periods and regulatory 
liabilities represent amounts that are expected to be returned to customers through future rate-setting processes. An operation 
qualifies for the use of RRA when it meets three criteria:
• a regulator must establish or approve the rates for the regulated services or activities
• the regulated rates must be designed to recover the cost of providing the services or products, and
• it is reasonable to assume that rates set at levels to recover the cost can be charged to (and collected from) customers 

because of the demand for services or products and the level of direct or indirect competition.

TC Energy's businesses that apply RRA currently include Canadian, U.S. and Mexico natural gas pipelines, and regulated 
U.S. natural gas storage. RRA is not applicable to the Company's liquids pipelines as the regulators' decisions regarding 
operations and tolls on those systems generally do not have an impact on timing of recognition of revenues and expenses. 

Revenue Recognition
The total consideration for services and products to which the Company expects to be entitled can include fixed and variable 
amounts. The Company has variable revenue that is subject to factors outside the Company's influence, such as market prices, 
actions of third parties and weather conditions. The Company considers this variable revenue to be "constrained" as it cannot be 
reliably estimated and, therefore, recognizes variable revenue when the service is provided.

Revenues from contracts with customers are recognized net of any commodity taxes collected from customers which are 
subsequently remitted to governmental authorities. The Company's contracts with customers include natural gas and liquids 
pipelines capacity arrangements and transportation contracts, power generation contracts, natural gas storage and other 
contracts. 

TC Energy Consolidated Financial Statements 2020   |  121

Canadian Natural Gas Pipelines
Capacity Arrangements and Transportation
Revenues from the Company's Canadian natural gas pipelines are generated from contractual arrangements for committed 
capacity and from the transportation of natural gas. 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. 

Revenues from the Company's Canadian natural gas pipelines under federal jurisdiction are subject to regulatory decisions by the 
CER. The tolls charged on these pipelines are based on revenue requirements designed to recover the costs of providing natural 
gas capacity for transportation services, which includes a return of and on capital, as approved by the CER. The Company's 
Canadian natural gas pipelines are generally not subject to earnings volatility related to variances in revenues and costs. These 
variances, except as related to incentive arrangements, are generally subject to deferral treatment and are recovered or 
refunded in future tolls. Revenues recognized prior to a CER decision on rates for that period reflect the CER's last approved 
return on equity (ROE) assumptions. Adjustments to revenues are recorded when the CER decision is received. Canadian natural 
gas pipelines' revenues are invoiced and received on a monthly basis. The Company does not take ownership of the natural gas 
that it transports for customers.

Other
The Company is contracted to provide pipeline construction services to a partially-owned entity for a development fee. The 
development fee is considered variable consideration due to refund provisions in the contract. The Company recognizes its 
estimate of the most likely amount of the variable consideration to which it will be entitled. The development fee is recognized 
over time as the services are provided based on the input method using an estimate of activity level.

U.S. Natural Gas Pipelines
Capacity Arrangements and Transportation
Revenues from the Company's U.S. natural gas pipelines are generated from contractual arrangements for committed capacity 
and from the transportation of natural gas. Revenues earned from firm contracted capacity arrangements are generally 
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 Company's U.S. natural gas pipelines 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 at the time a regulatory decision becomes final.           
U.S. natural gas pipelines' revenues are invoiced and received on a monthly basis. The Company does not take ownership of the 
natural gas that it transports for customers.

Natural Gas Storage and Other
Revenues from the Company's regulated U.S. natural gas storage services are generated mainly from firm committed capacity 
storage contracts. The performance obligation in these contracts is the reservation of a specified amount of capacity for storage 
including specifications with regards to the amount of natural gas that can be injected or withdrawn on a daily basis. Revenues 
are recognized ratably over the contract period for firm committed capacity regardless of the amount of natural gas that is 
stored, and when gas is injected or withdrawn for interruptible or volumetric-based services. Natural gas storage services 
revenues are invoiced and received on a monthly basis. The Company does not take ownership of the natural gas that it stores 
for customers.

The Company owns mineral rights associated with certain natural gas storage facilities. These mineral rights can be leased or 
contributed to producers of natural gas in return for a royalty interest which is recognized when natural gas and associated 
liquids are produced.

During 2019, TC Energy sold certain Columbia Midstream assets that were part of the acquisition of Columbia Pipeline Group, Inc.
(Columbia) in 2016. Prior to the sale, revenues from the Company's midstream natural gas services, including gathering, 
treating, conditioning, processing, compression and liquids handling services, were generated from contractual arrangements 
and were recognized ratably over the term of the contract. Midstream natural gas service revenues were invoiced and received 
on a monthly basis. The Company did not take ownership of the natural gas for which it provided midstream services. Refer to 
Note 27, Acquisitions and dispositions, for additional information regarding the sale of the Columbia Midstream assets. 

Net revenues earned from the sale of proprietary natural gas are recognized in the month of delivery.

Mexico Natural Gas Pipelines
Capacity Arrangements and Transportation
Revenues from the Company's Mexico natural gas pipelines are primarily collected based on CRE-approved negotiated firm 
capacity contracts and are generally recognized ratably over the term of the contract. Transportation revenues related to 
interruptible or volumetric-based services are recognized when the service is performed. Mexico natural gas pipelines' revenues 
are invoiced and received on a monthly basis. The Company does not take ownership of the natural gas that it transports for 
customers.

Other
The Company is contracted to provide operating services to a partially-owned entity for a fee which is recognized over time as 
services are provided. The Company's construction services to this entity have been performed and the related development fee 
has been recognized. Net revenues earned from the sale of proprietary natural gas are recognized in the month of delivery.

Liquids Pipelines
Capacity Arrangements and Transportation
Revenues from the Company's liquids pipelines are generated mainly from providing customers with firm capacity arrangements 
to transport crude oil. The performance obligation in these contracts is the reservation of a specified amount of capacity 
together with the transportation of crude oil on a monthly basis. Revenues earned from these arrangements are recognized 
ratably over the term of the contract regardless of the amount of crude oil that is transported. Revenues for interruptible or 
volumetric-based services are recognized when the service is performed. Liquids pipelines' revenues are invoiced and received 
on a monthly basis. The Company does not take ownership of the crude oil that it transports for customers.

Other
Net revenues earned from the sale of proprietary crude oil are recognized in the month of delivery.

Power and Storage
Power Generation 
Revenues from the Company's Power and Storage business are primarily derived from long-term contractual commitments to 
provide power capacity to meet the demands of the market, and from the sale of electricity to both centralized markets and to 
customers. Power generation revenues also include revenues from the sale of steam to customers. Revenues and capacity 
payments are recognized as the services are provided and as electricity and steam is delivered. Power generation revenues are 
invoiced and received on a monthly basis.

Natural Gas Storage and Other
Non-regulated natural gas storage contracts include park, loan and term storage arrangements. Revenues are recognized as the 
services are provided. Term storage revenues are invoiced and received on a monthly basis. Revenues earned from the sale of 
proprietary natural gas are recognized in the month of delivery. Revenues from ancillary services are recognized as the service is 
provided. The Company does not take ownership of the natural gas that it stores for customers.

Cash and Cash Equivalents
The Company's Cash and cash equivalents consist of cash and highly liquid short-term investments with original maturities of 
three months or less and are recorded at cost, which approximates fair value.

Inventories
Inventories primarily consist of materials and supplies including spare parts and fuel, proprietary crude oil in transit and 
proprietary natural gas inventory in storage. Inventories are carried at the lower of cost and net realizable value.

Assets Held for Sale
The Company classifies assets as held for sale when management approves and commits to a formal plan to actively market a 
disposal group and expects the sale to close within the next 12 months. Upon classifying an asset as held for sale, the asset is 
recorded at the lower of its carrying amount or its estimated fair value, net of selling costs, and any losses are recognized in net 
income. Gains related to the expected sale of these assets are not recognized until the transaction closes. Once an asset is 
classified as held for sale, depreciation expense is no longer recorded.

Plant, Property and Equipment

Natural Gas Pipelines
Plant, property and equipment for natural gas pipelines is carried at cost. Depreciation is calculated on a straight-line basis once 
the assets are ready for their intended use. Pipeline and compression equipment are depreciated at annual rates ranging from 
0.6 per cent to seven per cent, and metering and other plant equipment are depreciated at various rates reflecting their 
estimated useful lives. The cost of major overhauls of equipment is capitalized and depreciated over the estimated service lives 
of the overhauls. The cost of regulated natural gas pipelines includes an allowance for funds used during construction (AFUDC) 
consisting of a debt component and an equity component based on the rate of return on rate base approved by regulators. 
AFUDC is reflected as an increase in the cost of the assets in Plant, property and equipment with a corresponding credit 
recognized in Allowance for funds used during construction in the Consolidated statement of income. The equity component of 
AFUDC is a non-cash expenditure. Interest is capitalized during construction of non-regulated natural gas pipelines. 

Natural gas pipelines' linepack and natural gas storage base gas are valued at cost and are maintained to ensure adequate 
pressure exists to transport natural gas through pipelines and deliver natural gas held in storage. Linepack and base gas are not 
depreciated.

When rate-regulated natural gas pipelines retire plant, property and equipment from service, the original book cost is removed 
from the gross plant amount and recorded as a reduction to accumulated depreciation with no amount recorded to net income. 
Costs incurred to remove plant, property and equipment from service, net of any salvage proceeds, are also recorded in 
accumulated depreciation.

Other
The Company participates as a working interest partner in the development of certain Marcellus and Utica acreage. The working 
interest allows the Company to invest in drilling activities in addition to receiving a royalty interest in well production. The 
Company uses the successful efforts method of accounting for natural gas and crude oil resulting from its portion of drilling 
activities. Capitalized well costs are depleted based on the units of production method.

Prior to its sale in 2019, plant, property and equipment for Columbia Midstream was carried at cost. Depreciation was calculated 
on a straight-line basis once the assets were ready for their intended use. Gathering and processing facilities were depreciated at 
annual rates ranging from 1.7 per cent to 2.5 per cent, and other plant and equipment were depreciated at various rates 
reflecting their estimated useful lives. When these assets were retired from plant, property and equipment, the original book 
cost and related accumulated depreciation were derecognized and any gain or loss was recorded in net income. Refer to         
Note 27, Acquisitions and dispositions, for additional information.

Liquids Pipelines
Plant, property and equipment for liquids pipelines is carried at cost. Depreciation is calculated on a straight-line basis once the 
assets are ready for their intended use. Pipeline and pumping equipment are depreciated at annual rates ranging from               
two per cent to 2.5 per cent, and other plant and equipment are depreciated at various rates reflecting their estimated useful 
lives. The cost of these assets includes interest capitalized during construction. When liquids pipelines retire plant, property and 
equipment from service, the original book cost and related accumulated depreciation are derecognized and any gain or loss is 
recorded in net income.

124  |   TC Energy Consolidated Financial Statements 2020

Power and Storage
Plant, property and equipment for Power and Storage assets are recorded at cost and, once the assets are ready for their 
intended use, depreciated by major component on a straight-line basis over their estimated service lives at average annual rates 
ranging from two per cent to 20 per cent. Other equipment is depreciated at various rates reflecting their estimated useful lives. 
The cost of major overhauls of equipment is capitalized and depreciated over the estimated service lives of the overhauls. 
Interest is capitalized on facilities under construction. When these assets are retired from plant, property and equipment, the 
original book cost and related accumulated depreciation are derecognized and any gain or loss is recorded in net income. 

Natural gas storage base gas, which is valued at original cost, represents gas volumes that are maintained to ensure adequate 
reservoir pressure exists to deliver gas held in storage. Base gas is not depreciated.

Corporate
Corporate plant, property and equipment is recorded at cost and depreciated on a straight-line basis over its estimated useful 
life at average annual rates ranging from four per cent to 20 per cent.

Capital Projects in Development
The Company capitalizes project costs once advancement of the project to a construction stage is probable or costs are 
otherwise likely to be recoverable. The Company also capitalizes interest costs for non-regulated projects in development and 
AFUDC for regulated projects in development. Capital projects in development are included in Other long-term assets on the 
Consolidated balance sheet. These represent larger projects that generally require regulatory or other approvals before physical 
construction can begin. Once approvals are received, projects are moved to plant, property and equipment under construction.

Leases
On January 1, 2019, the Company adopted the FASB's new lease guidance using optional transition relief. Results reported for 
2020 and 2019 reflect the application of the new guidance while the 2018 comparative results were prepared and reported 
under previous lease guidance.

Lessee Accounting Policy
The Company determines if an arrangement is a lease at inception of the contract. Operating leases are recognized as           
right-of-use (ROU) assets and included in Plant, property, and equipment while corresponding liabilities are included in Accounts 
payable and other and Other long-term liabilities on the Consolidated balance sheet.

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease 
payments over the lease term at the commencement date of the lease agreement. Lease terms may include options to extend or 
terminate the lease when it is reasonably certain that the Company will exercise that option. As the Company's lease contracts 
do not provide an implicit interest rate, the Company uses its incremental borrowing rate based on the information available at 
commencement date in determining the present value of future payments. Operating lease expense is recognized on a     
straight-line basis over the lease term and included in Plant operating costs and other in the Consolidated statement of income.

The Company applies the practical expedients to not recognize ROU assets or lease liabilities for leases that qualify for the      
short-term lease recognition exemption and to not separate lease and non-lease components for all leases for which the 
Company is a lessee.

Lessor Accounting Policy
The Company is the lessor within certain contracts and these are accounted for as operating leases. The Company recognizes 
lease payments as income over the lease term on a straight-line basis. Variable lease payments are recognized as income in the 
period in which they occur.

The Company applies the practical expedient to not separate lease and non-lease components for facility and liquids tank 
terminals for which the Company is the lessor.

Impairment of Long-Lived Assets
The Company reviews long-lived assets such as plant, property and equipment, equity investments and capital projects in 
development for impairment whenever events or changes in circumstances indicate the carrying value may not be recoverable. 
If the total of the estimated undiscounted future cash flows for an asset within plant, property and equipment, or the estimated 
selling price of any long-lived asset is less than the carrying value of an asset, an impairment loss is recognized for the excess of 
the carrying value over the estimated fair value of the asset.

TC Energy Consolidated Financial Statements 2020   |  125

Acquisitions and Goodwill
The Company accounts for business combinations using the acquisition method of accounting and, accordingly, the assets and 
liabilities of the acquired entities are primarily measured at their estimated fair values at the date of acquisition. The excess of 
the fair value of the consideration transferred over the estimated fair value of the net assets acquired is classified as goodwill. 
Goodwill is not amortized and is tested for impairment on an annual basis, or more frequently if events or changes in 
circumstances indicate that it might be impaired.

The annual review for goodwill impairment is performed at the reporting unit level which is one level below the Company's 
operating segments. The Company can initially assess qualitative factors to determine whether events or changes in 
circumstances indicate that goodwill might be impaired. The factors the Company considers include, but are not limited to, 
macroeconomic conditions, industry and market considerations, current valuation multiples and discount rates, cost factors, 
historical and forecasted financial results, and events specific to that reporting unit. If the Company concludes that it is not more 
likely than not that the fair value of the reporting unit is greater than its carrying value, the Company will then perform a 
quantitative goodwill impairment test. The Company can elect to proceed directly to the quantitative goodwill impairment test 
for any of its reporting units. If the quantitative goodwill impairment test is performed, the Company compares the fair value of 
the reporting unit to its carrying value, including its goodwill. If the carrying value of a reporting unit exceeds its fair value, 
goodwill impairment is measured at the amount by which the reporting unit’s carrying value exceeds its fair value.

When a portion of a reporting unit that constitutes a business is disposed, goodwill associated with that business is included in 
the carrying amount of the business in determining the gain or loss on disposal. The amount of goodwill disposed is determined 
based on the relative fair values of the business to be disposed and the portion of the reporting unit that will be retained. A 
goodwill impairment test will be completed for both the goodwill disposed and the portion of the goodwill that will be retained.

Loans and Receivables
Loans receivable from affiliates and accounts receivable are measured at amortized cost.

Impairment of Financial Assets
The Company reviews financial assets carried at amortized cost for impairment using the lifetime expected loss of the financial 
asset at initial recognition and throughout the life of the financial asset. TC Energy uses historical credit loss and recovery data, 
adjusted for management's judgment regarding current economic and credit conditions, along with supportable forecasts to 
determine any impairment, which is recognized in Plant operating costs and other.

Power Purchase Arrangements
A power purchase arrangement (PPA) is a long-term contract for the purchase or sale of power on a predetermined basis.            
TC Energy has PPAs for the sale of power that are accounted for as operating leases where TC Energy is the lessor. 

Restricted Investments
The Company has certain investments that are restricted as to their withdrawal and use. These restricted investments are 
classified as available for sale and are recorded at fair value on the Consolidated balance sheet.

As a result of the CER’s Land Matters Consultation Initiative (LMCI), TC Energy is required to collect funds to cover estimated 
future pipeline abandonment costs for larger CER-regulated Canadian pipelines. Funds collected are placed in trusts that hold 
and invest the funds and are accounted for as restricted investments (LMCI restricted investments). LMCI restricted investments 
may only be used to fund the abandonment of the CER-regulated pipeline facilities, therefore, a corresponding regulatory 
liability is recorded on the Consolidated balance sheet. The Company also has other restricted investments that have been set 
aside to fund insurance claim losses to be paid by the Company's wholly-owned captive insurance subsidiary.

126  |   TC Energy Consolidated Financial Statements 2020

Income Taxes
The Company uses the asset and liability method of accounting for income taxes. This method requires the recognition of 
deferred income tax assets and liabilities for future tax consequences attributable to differences between the financial 
statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and 
liabilities are measured using enacted tax rates at the balance sheet date that are anticipated to apply to taxable income in the 
years in which temporary differences are expected to be reversed or settled. Changes to these balances are recognized in net 
income in the period in which they occur, except for changes in balances related to regulated natural gas pipelines which are 
deferred until they are refunded or recovered in tolls, as permitted by the regulator. Deferred income tax assets and liabilities are 
classified as non-current on the Consolidated balance sheet.

Canadian income taxes are not provided on the unremitted earnings of foreign investments that the Company does not intend 
to repatriate in the foreseeable future.

Asset Retirement Obligations
The Company recognizes the fair value of a liability for asset retirement obligations (ARO) in the period in which it is incurred, 
when a legal obligation exists and a reasonable estimate of fair value can be made. The fair value is added to the carrying 
amount of the associated asset and the liability is accreted through charges to Plant operating costs and other in the 
Consolidated statement of income.

In determining the fair value of ARO, the following assumptions are used:
• the expected retirement date
• the scope and cost of abandonment and reclamation activities that are required, and 
• appropriate inflation and discount rates.

The Company's AROs are substantively related to its power generation facilities. The scope and timing of asset retirements 
related to the Company's natural gas and liquids pipelines and storage facilities are indeterminable because the Company 
intends to operate them as long as there is supply and demand. As a result, the Company has not recorded an amount for ARO 
related to these assets.

Environmental Liabilities
The Company records liabilities on an undiscounted basis for environmental remediation efforts that are likely to occur and 
where the cost can be reasonably estimated. These estimates, including associated legal costs, are based on available 
information using existing technology and enacted laws and regulations, and are subject to revision in future periods based on 
actual costs incurred or new circumstances. Amounts expected to be recovered from other parties, including insurers, are 
recorded as an asset separate from the associated liability.

Emission allowances or credits purchased for compliance are recorded on the Consolidated balance sheet at historical cost and 
expensed when they are utilized or cancelled/retired by government agencies. Compliance costs are expensed when incurred. 
Allowances granted to or internally generated by TC Energy are not attributed a value for accounting purposes. When required, 
TC Energy accrues emission liabilities on the Consolidated balance sheet using the best estimate of the amount required to settle 
the compliance obligation. Allowances and credits not used for compliance are sold and any gain or loss is recorded in Revenues.

Stock Options and Other Compensation Programs
TC Energy's Stock Option Plan permits options for the purchase of common shares to be awarded to certain employees, including 
officers. Stock options granted are recorded using the fair value method. Under this method, compensation expense is measured 
at the grant date based on the fair value as calculated using a binomial model and is recognized on a straight-line basis over the 
vesting period with an offset to Additional paid-in capital. Forfeitures are accounted for when they occur. Upon exercise of stock 
options, amounts originally recorded against Additional paid-in capital are reclassified to Common shares on the Consolidated 
balance sheet.

The Company has medium-term incentive plans under which payments are made to eligible employees. The expense related to 
these incentive plans is accounted for on an accrual basis. Under these plans, benefits vest when certain conditions are met, 
including the employees' continued employment during a specified period and achievement of specified corporate performance 
targets.

TC Energy Consolidated Financial Statements 2020   |  127

Employee Post-Retirement Benefits
The Company sponsors defined benefit pension plans (DB Plans), defined contribution plans (DC Plans), savings plans and other 
post-retirement benefit plans. Contributions made by the Company to the DC Plans and savings plans are expensed in the period 
in which contributions are made. The cost of the DB Plans and other post-retirement benefits received by employees is 
actuarially determined using the projected benefit method pro-rated based on service, and management's best estimate of 
expected plan investment performance, salary escalation, retirement age of employees and expected health care costs.

The DB Plans' assets are measured at fair value at December 31 of each year. The expected return on the DB Plans' assets is 
determined using market-related values based on a five-year moving average value for all of the DB Plans' assets. Past service 
costs are amortized over the expected average remaining service life (EARSL) of the employees. Adjustments arising from plan 
amendments are amortized on a straight-line basis over the EARSL of employees active at the date of amendment. The Company 
recognizes the overfunded or underfunded status of its DB Plans as an asset or liability, respectively, on its Consolidated balance 
sheet and recognizes changes in that funded status through Other comprehensive (loss)/ income (OCI) in the year in which the 
change occurs. The excess of net actuarial gains or losses over 10 per cent of the greater of the benefit obligation and the 
market-related value of the DB Plans' assets, if any, is amortized out of Accumulated other comprehensive income /(loss) (AOCI) 
and into net income over the EARSL of the active employees. When the restructuring of a benefit plan gives rise to both a 
curtailment and a settlement, the curtailment is accounted for prior to the settlement.

For certain regulated operations, post-retirement benefit amounts are recoverable through tolls as benefits are funded. The 
Company records any unrecognized gains or losses or changes in actuarial assumptions related to these post-retirement benefit 
plans as either regulatory assets or liabilities. The regulatory assets or liabilities are amortized on a straight-line basis over the 
EARSL of active employees.

Foreign Currency Transactions and Translation
Foreign currency transactions are those transactions whose terms are denominated in a currency other than the currency of the 
primary economic environment in which the Company or reporting subsidiary operates. This is referred to as the functional 
currency. Transactions denominated in foreign currencies are translated into the functional currency using the exchange rate 
prevailing at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are translated to the 
functional currency using the rate of exchange in effect at the balance sheet date whereas non-monetary assets and liabilities 
are translated at the historical rate of exchange in effect on the date of the transaction. Exchange gains and losses resulting from 
translation of monetary assets and liabilities are recorded in net income except for exchange gains and losses on any foreign 
currency debt related to Canadian regulated natural gas pipelines, which are deferred until they are refunded or recovered in 
tolls, as permitted by the CER.

Gains and losses arising from translation of foreign operations' functional currencies to the Company's Canadian dollar reporting 
currency are reflected in OCI until the operations are sold, at which time the gains and losses are reclassified to net income. Asset 
and liability accounts are translated at the period-end exchange rates while revenues, expenses, gains and losses are translated 
at the exchange rates in effect at the time of the transaction. The Company's U.S. dollar-denominated debt and certain 
derivative hedging instruments have been designated as a hedge of the net investment in foreign subsidiaries and, as a result, 
the unrealized foreign exchange gains and losses on the U.S. dollar-denominated debt and derivatives are also reflected in OCI. 

Derivative Instruments and Hedging Activities
All derivative instruments are recorded on the Consolidated balance sheet at fair value, unless they qualify for and are 
designated under a normal purchase and normal sales exemption, or are considered to meet other permitted exemptions.

The Company applies hedge accounting to arrangements that qualify for and are designated for hedge accounting treatment. 
This includes fair value and cash flow hedges and hedges of foreign currency exposures of net investments in foreign operations. 
Hedge accounting is discontinued prospectively if the hedging relationship ceases to be effective or the hedging or hedged 
items cease to exist as a result of maturity, expiry, sale, termination, cancellation or exercise.

128  |   TC Energy Consolidated Financial Statements 2020

In a fair value hedging relationship, the carrying value of the hedged item is adjusted for changes in fair value attributable to the 
hedged risk and these changes are recognized in net income. Changes in the fair value of the hedged item, to the extent that the 
hedging relationship is effective, are offset by changes in the fair value of the hedging item, which are also recorded in net 
income. Changes in the fair value of foreign exchange and interest rate fair value hedges are recorded in Interest income and 
other and Interest expense, respectively. If hedge accounting is discontinued, the carrying value of the hedged item is no longer 
adjusted and the cumulative fair value adjustments to the carrying value of the hedged item are amortized to net income over 
the remaining term of the original hedging relationship.

In a cash flow hedging relationship, the change in the fair value of the hedging derivative is recognized in OCI. When hedge 
accounting is discontinued, the amounts recognized previously in AOCI are reclassified to Revenues, Interest expense and 
Interest income and other, as appropriate, during the periods when the variability in cash flows of the hedged item affects net 
income or as the original hedged item settles. Gains and losses on derivatives are reclassified immediately to net income from 
AOCI when the hedged item is sold or terminated early, or when it becomes probable that the anticipated transaction will 
not occur. Termination payments on interest rate derivatives are classified as a financing activity on the Consolidated statement 
of cash flows.

In hedging the foreign currency exposure of a net investment in a foreign operation, the foreign exchange gains and losses on 
the hedging instruments are recognized in OCI. The amounts recognized previously in AOCI are reclassified to net income in the 
event the Company reduces its net investment in a foreign operation.

In some cases, derivatives do not meet the specific criteria for hedge accounting treatment. In these instances, the changes in 
fair value are recorded in net income in the period of change.

Gains and losses arising from changes in the fair value of derivatives accounted for as part of RRA, including those that qualify for 
hedge accounting treatment, are refunded or recovered through the tolls charged by the Company. As a result, these gains and 
losses are deferred as regulatory assets or liabilities and are refunded to or collected from ratepayers in subsequent periods when 
the derivative settles.

Derivatives embedded in other financial instruments or contracts (host instrument) are recorded as separate derivatives. 
Embedded derivatives are measured at fair value if their economic characteristics are not clearly and closely related to those of 
the host instrument, their terms are the same as those of a stand-alone derivative and the total contract is not held for trading or 
accounted for at fair value. When changes in the fair value of embedded derivatives are measured separately, they are included 
in net income.

Long-Term Debt Transaction Costs and Issuance Costs
The Company records long-term debt transaction costs and issuance costs as a deduction from the carrying amount of the 
related debt liability and amortizes these costs using the effective interest method except those related to the Canadian natural 
gas regulated pipelines, which continue to be amortized on a straight-line basis in accordance with the provisions of regulatory 
tolling mechanisms.

Guarantees
Upon issuance, the Company records the fair value of certain guarantees entered into by the Company on behalf of a        
partially-owned entity or by partially-owned entities for which contingent payments may be made. The fair value of these 
guarantees is estimated by discounting the cash flows that would be incurred by the Company if letters of credit were used in 
place of the guarantees as appropriate in the circumstances. Guarantees are recorded as an increase to Equity investments or 
Plant, property and equipment and a corresponding liability is recorded in Other long-term liabilities. The release from the 
obligation is recognized either over the term of the guarantee or upon expiration or settlement of the guarantee.

3.  ACCOUNTING CHANGES

Changes in Accounting Policies for 2020 

Measurement of credit losses on financial instruments
In June 2016, the 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. 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 was 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 Company's consolidated financial statements. 

Implementation costs of cloud computing arrangements
In August 2018, the FASB issued new guidance requiring an entity in a hosting arrangement that is a service contract to follow 
the guidance for internal-use software to determine which implementation costs should be capitalized as an asset and which 
costs should be expensed. The guidance also requires the entity to amortize the capitalized implementation costs of a hosting 
arrangement over the term of the arrangement. This guidance was effective January 1, 2020 and was applied prospectively. The 
adoption of this new guidance did not have a material impact on the Company'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 was effective 
January 1, 2020 and was applied on a retrospective basis. The adoption of this new guidance did not have an impact on the 
Company's consolidated financial statements.

Defined benefit plans
In August 2018, the FASB issued new guidance which amends and clarifies disclosure requirements related to defined benefit 
pension and other post-retirement benefit plans. This new guidance was effective for annual disclosure requirements at       
December 31, 2020 and applied on a retrospective basis. The adoption of this new guidance, which is limited to disclosures only, 
did not have a material impact on the Company's consolidated financial statements.

Reference rate reform
In response to the expected cessation of the London Interbank Offered Rate (LIBOR), of which certain rate settings may cease to 
be published at the end of 2021 with full cessation expected by mid-2023, the FASB issued new optional guidance in March 2020 
that eases the potential burden in accounting for such 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 Company has applied an optional expedient allowing an entity to assume that the hedged forecasted 
transaction in a cash flow hedge is probable of occurring. The Company is continuing to identify and analyze existing agreements 
to determine the effect of reference rate reform on its consolidated financial statements. The Company will continue to evaluate 
the timing and potential impact of adoption for other optional expedients when deemed necessary.

Future Accounting Changes

Income taxes
In December 2019, the FASB issued new guidance that simplified the accounting for income taxes and clarified existing guidance. 
This new guidance is effective January 1, 2021, and is not expected to have a material impact on the Company's consolidated 
financial statements.

During the year ended December 31, 2020, $18 million (2019 – $6 million) of revenues were recognized that were included in contract liabilities at the 
beginning of the year.

Contract assets and long-term contract assets primarily relate to the Company’s right to revenues for services completed but not 
invoiced at the reporting date on long-term committed capacity natural gas pipelines contracts. The change in contract assets is 
primarily related to the transfer to Accounts receivable when these rights become unconditional and the customer is invoiced, as 
well as the recognition of additional revenues that remain to be invoiced. Contract liabilities and long-term contract liabilities 
primarily relate to force majeure fixed capacity payments received on long-term capacity arrangements in Mexico. 

Future Revenues from Remaining Performance Obligations
As at December 31, 2020, future revenues from long-term pipeline capacity arrangements and transportation as well as natural 
gas storage and other contracts extending through 2047 are approximately $25.5 billion, of which approximately $3.7 billion is 
expected to be recognized in 2021. 

A significant portion of the Company's revenues are considered constrained and therefore not included in the future revenue 
amounts above as the Company uses the following practical expedients:
• right to invoice practical expedient – applied to all U.S. and certain Mexico rate-regulated natural gas pipeline capacity 

arrangements and flow-through revenues

• variable consideration practical expedient – applied to the following variable revenues:

◦ interruptible transportation service revenues as volumes cannot be estimated
◦ liquids pipelines capacity revenues based on volumes transported
◦ power generation revenues related to market prices that are subject to factors outside the Company's influence

• contracts for a duration of one year or less.

In addition, future revenues from the Company's Canadian natural gas pipelines' regulated firm capacity contracts include fixed 
revenues only for the time periods that approved tolls under current rate settlements are in effect and certain, which is currently 
one year.

Includes Foothills, Ventures LP and Great Lakes Canada.
Includes the Coastal GasLink pipeline project at December 31, 2019. On May 22, 2020, the Company completed the sale of a 65 per cent equity interest in 
Coastal GasLink Pipeline Limited Partnership and subsequently commenced accounting for its remaining investment using the equity method. Refer to Note 27, 
Acquisitions and dispositions, for additional information. 
Includes Portland, North Baja, Tuscarora, Crossroads and mineral rights.
On March 31, 2020, TC Energy announced that it would proceed with construction of the Keystone XL pipeline. As a result, related capitalized development 
costs of $1.7 billion were transferred to Plant, property and equipment from Capital projects in development within Other long-term assets on the Consolidated 
balance sheet. On January 20, 2021, the Presidential Permit for the Keystone XL pipeline was revoked. Refer to Note 30, Subsequent events, for additional 
information. 

Bison Impairment
At December 31, 2018, the Company evaluated its investment in its Bison natural gas pipeline for impairment in connection with 
the termination of certain customer transportation agreements which released the Company from providing any future services. 
With the loss of these future cash flows and the persistence of unfavourable market conditions which have inhibited system 
flows on the pipeline, the Company determined that the asset’s remaining carrying value was no longer recoverable and 
recognized a non-cash impairment charge of $722 million pre tax in its U.S. Natural Gas Pipelines segment. The non-cash charge 
was recorded in Goodwill and other asset impairment charges in the Consolidated statement of income. As Bison is a                   
TC PipeLines, LP asset, in which the Company had a 25.5 per cent interest, the Company's share of the impairment charge, after 
tax and net of non-controlling interests, was $140 million.

The termination of the transportation agreements resulted in the receipt of $130 million in termination payments which were 
recorded in Revenues in 2018. The Company's share of this amount, after tax and net of non-controlling interests, was               
$25 million.

8.  LEASES

As a Lessee
The Company has operating leases for corporate offices, other various premises, equipment and land. Some leases have an 
option to renew for periods of one to 25 years, and some may include options to terminate the lease within one year. Payments 
due under lease contracts include fixed payments plus, for many of the Company's leases, variable payments such as a 
proportionate share of the buildings' property taxes, insurance and common area maintenance. The Company subleases some of 
the leased premises.

Operating lease cost was as follows:

As at December 31, 2020, the carrying value of the ROU assets recorded under operating leases was $473 million                      
(2019 – $530 million) and is included in Plant, property and equipment on the Consolidated balance sheet.

As a Lessor
The Grandview and Bécancour power plants in the Power and Storage segment are accounted for as operating leases. In 
addition, the Company has long-term PPAs for the sale of power for the Power and Storage lease assets which expire between 
2024 and 2026. 

The Northern Courier pipeline in the Liquids Pipelines segment was accounted for as an operating lease prior to the July 2019 sale 
of an 85 per cent equity interest in Northern Courier. The Company uses the equity method to account for its remaining              
15 per cent interest in the Company's consolidated financial statements. Refer to Note 27, Acquisitions and dispositions, for 
additional information. 

Some leases contain variable lease payments that are based on operating hours and the reimbursement of variable costs, and 
options to purchase the underlying asset at fair value or based on a formula considering the remaining fixed payments. Lessees 
have rights under some leases to terminate under certain circumstances. 

The Company also leases liquids tanks which are accounted for as operating leases.

The fixed portion of the operating lease income recorded by the Company for the year ended December 31, 2020 was               
$130 million (2019 – $180 million). Operating lease income in 2018 was $373 million.

Future lease payments to be received under operating leases are as follows:

Classified as a non-consolidated VIE. Refer to Note 29, Variable interest entities, for additional information.
On May 22, 2020, TC Energy completed the sale of a 65 per cent equity interest in Coastal GasLink Pipeline Limited Partnership and subsequently applied the 
equity method to account for its 35 per cent retained equity interest in the jointly controlled entity. Refer to Note 27, Acquisitions and dispositions, for 
additional information. At December 31, 2020, the difference between the carrying value of the investment and the underlying equity in the net assets of 
Coastal GasLink Pipeline Limited Partnership was $188 million due mainly to the fair value assessment of assets at the time of partial monetization.
At December 31, 2020, the difference between the carrying value of the investment and the underlying equity in the net assets of Northern Border was     
US$116 million (2019 – US$116 million) due mainly to the fair value assessment of assets at the time of acquisition.
At December 31, 2020, the difference between the carrying value of the investment and the underlying equity in the net assets of Iroquois was US$39 million 
(2019 – US$40 million) due mainly to the fair value assessment of the assets at the times of acquisition.

Note 27, Acquisitions and dispositions, for additional information.
Sur de Texas was placed into service in September 2019. TC Energy has a 60 per cent equity interest and, as a jointly controlled entity, applies the equity  
method of accounting. Income from equity investments recorded in the Corporate segment reflects the Company's proportionate share of Sur de Texas foreign 
exchange gains and losses on the peso-denominated loans from affiliates which are fully offset in Interest income and other in the Consolidated statement of 
income. At December 31, 2020, the difference between the carrying value of the investment and the underlying equity in the net assets of Sur de Texas was 
US$79 million (2019 – nil) due mainly to fees earned from the successful construction of the pipeline.
At December 31, 2020, the difference between the carrying value of the investment and the underlying equity in the net assets of Grand Rapids was $98 million 
(2019 – $101 million) due mainly to interest capitalized during construction. 
In July 2019, TC Energy completed the sale of an 85 per cent equity interest in Northern Courier, and subsequently applied the equity method to account for its             
15 per cent retained equity interest in the jointly controlled entity. Refer to Note 27, Acquisitions and dispositions, for additional information. At      
December 31, 2020, the difference between the carrying value of the investment and the underlying equity in the net assets of Northern Courier was                
$56 million (2019 – $62 million) due mainly to the fair value of guarantees and the fair value assessment of assets at the time of partial monetization.
At December 31, 2020, the difference between the carrying value of the investment and the underlying equity in the net assets of Bruce Power was $796 million

Related party transactions are conducted in the normal course of business and are measured at the exchange amount, which is 
the amount of consideration established and agreed to by the related parties.

Coastal GasLink Pipeline Limited Partnership
In conjunction with the equity sale on May 22, 2020, the Company entered into a subordinated demand revolving credit facility 
with Coastal GasLink Pipeline Limited Partnership (Coastal GasLink LP), which had a capacity of $200 million at            
December 31, 2020. This facility provides additional short-term liquidity and funding flexibility to the project and bears interest 
at a floating market-based rate. At December 31, 2020, there were no amounts outstanding on this facility. Refer to Note 27, 
Acquisitions and dispositions, for additional information.

Sur de Texas
TC Energy holds a 60 per cent equity interest in a joint venture with IEnova to own the Sur de Texas pipeline, for which TC Energy 
is the operator. In 2017, TC Energy entered into a MXN$21.3 billion unsecured revolving credit facility with the joint venture, 
which bears interest at a floating rate and matures in March 2022. At December 31, 2020, Loan receivable from affiliate on the 
Company's Consolidated balance sheet reflected a MXN$20.9 billion or $1.3 billion (2019 – MXN$20.9 billion or $1.4 billion) loan 
receivable from the Sur de Texas joint venture which represents TC Energy's proportionate share of long-term debt financing to 
the joint venture.

TC Energy's businesses that apply RRA currently include almost all of the Canadian, U.S. and Mexico natural gas pipelines and 
certain U.S. natural gas storage operations. Rate-regulated businesses account for and report assets and liabilities consistent 
with the resulting economic impact of the regulators' established rates, provided the rates are designed to recover the costs of 
providing the regulated service and the competitive environment makes it probable that such rates can be charged and 
collected. Certain revenues and expenses subject to utility regulation or rate determination that would otherwise be reflected in 
the statement of income are deferred on the balance sheet and are expected to be recovered from or refunded to customers in 
future service rates. 

Canadian Regulated Operations
The majority of TC Energy's Canadian natural gas pipelines are regulated by the CER under the Canadian Energy Regulator Act 
(CER Act). In August 2019, the CER and CER Act replaced the NEB and the National Energy Board Act (NEB Act), respectively. The 
impact assessment and decision-making for designated major transboundary pipeline projects also changed at that time with 
the implementation of the new Impact Assessment Act which required designated projects, on a prospective basis, to be 
assessed by the Impact Assessment Agency of Canada. TC Energy projects submitted to the NEB for review prior to                
August 28, 2019 will continue to be assessed under the previous NEB Act in accordance with the transitional rules under the     
CER Act.

The CER regulates the construction and operation of facilities, and the terms and conditions of services, including rates, for the 
Company's Canadian regulated natural gas transmission systems under federal jurisdiction.

TC Energy's Canadian natural gas transmission services are supplied under natural gas transportation tariffs that provide for cost 
recovery, including return of and return on capital as approved by the CER or NEB. Rates charged for these services are typically 
set through a process that involves filing an application with the regulator wherein forecasted operating costs, including a return 
of and on capital, determine the revenue requirement for the upcoming year or multiple years. To the extent actual costs and 
revenues are more or less than forecasted costs and revenues, the regulators generally allow the difference to be deferred to a 
future period and recovered or refunded in rates at that time. Differences between actual and forecasted costs that the 
regulator does not allow to be deferred are included in the determination of net income in the year they occur. The Company's 
most significant regulated Canadian natural gas pipelines, based on total operated pipe length, are described below.

NGTL System
The NGTL System currently operates under the terms of the 2020-2024 Revenue Requirement Settlement approved by the CER 
on August 17, 2020. The settlement, effective January 1, 2020, includes an ROE of 10.1 per cent on 40 per cent deemed common 
equity, provides the NGTL System with the opportunity to increase depreciation rates if tolls fall below projected levels and 
includes an incentive mechanism for certain operating costs where variances from projected amounts are shared between the 
NGTL System and its customers. It also includes a mechanism to review the settlement should tolls exceed a pre-determined 
level, without affecting the equity return.

NGTL System's 2019 and 2018 results reflect the terms of the 2018-2019 Revenue Requirement Settlement which included an ROE 
of 10.1 per cent on 40 per cent deemed common equity, a mechanism for sharing variances above and below a fixed annual 
operating, maintenance and administration amount and flow-through treatment of all other costs.

Canadian Mainline
The Canadian Mainline currently operates under the terms of the 2015-2030 Tolls Application approved in 2014 (the NEB 2014 
Decision). The terms in the 2015-2020 six-year settlement of the NEB 2014 Decision, which ended December 31, 2020, included 
an ROE of 10.1 per cent on deemed common equity of 40 per cent, an incentive mechanism that had both upside and downside 
risk and a $20 million after-tax annual TC Energy contribution to reduce the revenue requirement. Toll stabilization was achieved 
through the use of deferral accounts, namely the bridging amortization account and the long-term adjustment account (LTAA), 
to capture the surplus or shortfall between the Company's revenues and cost of service for each year over the 2015-2020 six-year 
fixed-toll term of the NEB 2014 Decision. The NEB 2014 Decision also directed TC Energy to file an application to review tolls for 
the 2018-2020 period. In December 2018, an NEB decision was received on the 2018-2020 Tolls Review (NEB 2018 Decision) 
which included an accelerated amortization of the December 31, 2017 LTAA balance and an increase to the composite 
depreciation rate from 3.2 per cent to 3.9 per cent. 

On April 17, 2020, the CER approved the six-year unanimous negotiated settlement (2021-2026 Mainline Settlement) filed in 
December 2019. Similar to previous settlements, the 2021-2026 Mainline Settlement maintains a base equity return of              
10.1 per cent on 40 per cent deemed common equity and includes an incentive to either achieve cost efficiencies and/or 
increase revenues on the pipeline with a beneficial sharing mechanism to both the shippers and TC Energy. An estimate of the 
remaining LTAA balance at the end of 2020 was included as an adjustment in the calculation of Mainline fixed tolls and 
amortized over the settlement term. Going forward, similar to the LTAA, the short-term adjustment accounts (STAA) captures 
the surplus or shortfall between system revenues and cost of service each year under the 2021-2026 Mainline Settlement. 

U.S. Regulated Operations
TC Energy's U.S. regulated natural gas pipelines operate under the provisions of the Natural Gas Act (NGA)of 1938, the Natural 
Gas Policy Act of 1978 and the Energy Policy Act of 2005, and are subject to the jurisdiction of FERC. The NGA grants FERC 
authority over the construction and operation of pipelines and related facilities, including the regulation of tariffs which 
incorporates maximum and minimum rates for services and allows U.S. regulated natural gas pipelines to discount or negotiate 
rates on a non-discriminatory basis. The Company's most significant regulated U.S. natural gas pipelines, based on effective 
ownership and total operated pipe length, are described below.

In 2018, FERC prescribed changes (2018 FERC Actions) related to H.R.1, the Tax Cuts and Jobs Act (U.S. Tax Reform), and income 
taxes for rate-making purposes in a master limited partnership (MLP) that impact future earnings and cash flows of                  
FERC-regulated pipelines. As part of the 2018 FERC Actions, FERC issued a Revised Policy Statement which created a presumption 
that entities whose earnings are not taxed through a corporation should not be permitted to recover an income tax allowance in 
their cost-of-service rates. In addition, FERC established that, to the extent an entity's income tax allowance should be 
eliminated from rates, it must also eliminate existing accumulated deferred income tax (ADIT) asset and liability balances from 
its rate base.

These 2018 FERC Actions also established a process and schedule by which all FERC-regulated interstate pipelines and natural gas 
storage facilities had to either (i) file a new uncontested rate settlement or (ii) file a FERC Form 501-G that quantified the 
isolated impact of U.S. Tax Reform and provided four options to address the impact for rate-making purposes.

TC Energy Consolidated Financial Statements 2020   |  145

Columbia Gas
Columbia Gas' natural gas transportation and storage services are provided under a tariff at rates subject to FERC approval. A 
FERC-approved modernization settlement provided for cost recovery and return on investment of up to US$1.5 billion from 
2013-2017 to modernize the Columbia Gas system thereby improving system integrity and enhancing service reliability and 
flexibility. An extension of this settlement was approved by FERC in 2016 which allows for the cost recovery and return on 
additional expanded scope investment of US$1.1 billion over a three-year period through 2020. 

Columbia Gas filed a general NGA Section 4 Rate Case with FERC on July 31, 2020 requesting an increase to Columbia Gas's 
maximum transportation rates expected to become effective February 1, 2021, subject to refund. The rate case continues to 
progress as expected, and the Company intends to pursue a collaborative process to reach a mutually beneficial outcome with its 
customers through settlement negotiations.

ANR Pipeline
ANR Pipeline operates under rates established through a FERC-approved rate settlement in 2016. Under terms of the 2016 
settlement, ANR Pipeline is no longer under a rate moratorium and is required to file for new rates to be effective no later than 
August 1, 2022.

On August 10, 2020, FERC terminated ANR Pipeline's 501-G proceeding and ruled that ANR Pipeline has complied with the      
one-time reporting requirement. Additionally, FERC stated it will not exercise its right to initiate a NGA Section 5 investigation 
into ANR’s effective rates at this time but may in the future, if warranted.

Columbia Gulf
Columbia Gulf reached a rate settlement with its customers, which was approved by FERC in December 2019, increasing 
Columbia Gulf’s recourse rates to take effect on August 1, 2020. This settlement establishes a rate case and tariff filing 
moratorium through August 1, 2022 and Columbia Gulf is required to file a general rate case under Section 4 of the NGA no later 
than January 31, 2027, with new rates to be effective August 1, 2027.

TC PipeLines, LP
TC Energy owns a 25.5 per cent interest in TC PipeLines, LP, which has ownership interests in eight wholly-owned or          
partially-owned natural gas pipelines serving major markets in the U.S. As TC PipeLines, LP is an MLP, all pipelines it owns wholly 
or in part were impacted by the 2018 FERC Actions which required these pipelines to eliminate their existing ADIT balance from 
rate base. Refer to Note 17, Income taxes, for additional information regarding the impact of these changes to TC Energy.

Great Lakes
Great Lakes reached a rate settlement with its customers, which was approved by FERC in February 2018, decreasing Great Lakes' 
maximum transportation rates by 27 per cent effective October 2017. This settlement does not contain a 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. In 
2018, as a result of the 2018 FERC Actions noted above, Great Lakes made a limited NGA Section 4 filing which had the effect of 
reducing rates by two per cent from what was in place previously. The reduction in rates became effective on February 1, 2019 
after the limited Section 4 filing was accepted by FERC.

On May 11, 2020, FERC terminated Great Lakes’ 501-G proceeding and ruled that Great Lakes has complied with the one-time 
reporting requirement. Additionally, FERC also stated that rate reductions provided for in its 2017 settlement and the                
two per cent 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 NGA Section 5 investigation to determine if    
Great Lakes is over-recovering on its current tariff rates.

Mexico Regulated Operations
TC Energy's Mexico natural gas pipelines are regulated by CRE and operate in accordance with CRE-approved tariffs. The rates in 
effect on TC Energy's Mexico natural gas pipelines were established based on CRE-approved contracts that provide for cost 
recovery, including a return of and on invested capital.

These regulatory assets and liabilities are underpinned by non-cash transactions or are recovered without an allowance for return as approved by the regulator. 
Accordingly, these regulatory assets or liabilities are not included in rate base and do not yield a return on investment during the recovery period.
Operating and debt-service regulatory assets and liabilities represent the accumulation of cost and revenue variances to be included in determination of rates in 
the following year.
These balances represent the regulatory offset to pension plan and other post-retirement benefit obligations to the extent the amounts are expected to be 
collected from or refunded to customers in future rates. 
Foreign exchange on long-term debt of the NGTL System represents the variance resulting from revaluing foreign currency-denominated debt instruments to 
the current foreign exchange rate from the historical foreign exchange rate at the time of issue. Foreign exchange gains and losses realized when foreign debt 
matures or is redeemed early are expected to be recovered or refunded through the determination of future tolls. 
This balance represents the amount ANR estimates would be required to refund to its customers for post-retirement and post-employment benefit amounts 
collected through its FERC-approved rates that have not been used to pay benefits to its employees. Pursuant to a FERC-approved rate settlement, the            
$40 million (US$32 million) balance at December 31, 2020 is subject to resolution through future regulatory proceedings and, accordingly, a settlement period 
cannot be determined at this time. 
These regulatory accounts are used to capture Canadian Mainline revenue and cost variances plus toll-stabilization adjustments during the 2015-2030 
settlement term. 
Under the terms of the 2021-2026 Mainline Settlement, $223 million will be amortized over the six-year settlement term and the residual of $4 million will be 
transferred to the STAA.
This balance represents the amounts collected in tolls from shippers and included in the LMCI restricted investments to fund future abandonment of the 
Company's CER-regulated pipeline facilities.
This balance represents anticipated costs of removal that have been, and continue to be, included in depreciation rates and collected in the service rates of 
certain rate-regulated operations for future costs to be incurred.
These balances represent the impact of U.S. Tax Reform. The regulatory liabilities will be amortized over varying terms that approximate the expected reversal 
of the underlying deferred tax liabilities that gave rise to the regulatory liabilities under the Reverse South Georgia Methodology.

As part of the annual goodwill impairment assessment at December 31, 2020, the Company evaluated qualitative factors 
impacting the fair value of the underlying reporting units. It was determined that it was more likely than not that the fair value 
of the reporting units exceeded their carrying amounts, including goodwill.

Sale of Columbia Midstream Assets
In August 2019, TC Energy completed the sale of certain Columbia Midstream assets. As these assets constituted a business, and 
there was goodwill within this reporting unit, $595 million of Columbia's goodwill allocated to these assets was released and 
netted in the pre-tax gain on sale. The amount released was determined based on the relative fair values of the assets sold and 
the portion of the reporting unit retained. The fair value of the reporting unit was determined using a discounted cash flow 
analysis. Refer to Note 27, Acquisitions and dispositions, for additional details.

Tuscarora
In 2018, the Company recorded a goodwill impairment charge of $79 million pre-tax within the U.S. Natural Gas Pipelines 
segment. The fair value of the reporting unit was determined using a discounted cash flow analysis. This non-cash charge was 
recorded in Goodwill and other asset impairment charges in the Consolidated statement of income. As Tuscarora is a                    
TC PipeLines, LP asset, the Company's share of this amount, after tax and net of non-controlling interests, was $15 million. The 
gross goodwill and accumulated impairment losses related to Tuscarora were US$82 million and US$59 million, respectively, on 
the Consolidated balance sheet at December 31, 2020 and 2019.

Keystone XL
On March 31, 2020, TC Energy announced that it would proceed with construction of the Keystone XL pipeline and, as a result, 
$1.7 billion of related capitalized development costs were transferred to Plant, property and equipment. At December 31, 2019, 
the amount included in Capital projects in development for this project was $1.5 billion.

Reimbursement of Coastal GasLink pipeline project costs
In November 2018, in accordance with provisions in the agreements with the LNG Canada joint venture participants, all five 
parties elected to collectively reimburse TC Energy $470 million representing costs incurred prior to receiving the Final 
Investment Decision (FID) on the Coastal GasLink pipeline project (Coastal GasLink). These payments were recorded as a 
reduction of the carrying value of Coastal GasLink costs which, subsequent to the FID, were reported in Plant, property and 
equipment until the sale of a 65 per cent equity interest in Coastal GasLink LP on May 22, 2020, at which point TC Energy's 
remaining investment was recorded in Equity investments. Refer to Note 27, Acquisitions and dispositions, for additional 
information.

Provisions of various credit arrangements with the Company's subsidiaries can restrict their ability to declare and pay dividends or make distributions under 
certain circumstances. If such restrictions apply, they may, in turn, have an impact on the Company's ability to declare and pay dividends on common and 
preferred shares. These credit arrangements also require the Company to comply with various affirmative and negative covenants and maintain certain financial 
ratios. At December 31, 2020, the Company was in compliance with all debt covenants.

At December 31, 2020, the Company has recognized the benefit of non-capital loss carryforwards of $3,671 million               
(2019 – $1,929 million) for federal and provincial purposes in Canada, which expire from 2030 to 2040. The Company has not yet 
recognized the benefit of capital loss carryforwards of $253 million (2019 – $598 million) for federal and provincial purposes in 
Canada, with no expiry date. The Company also has Ontario minimum tax credits of $106 million (2019 – $102 million), which 
expire from 2026 to 2040.

At December 31, 2020, the Company has fully recognized the benefit of net operating loss carryforwards of US$849 million 
(2019 – US$1,098 million) for federal purposes in the U.S., which expire from 2029 to 2037. 

At December 31, 2020, the Company has recognized the benefit of net operating loss carryforwards of US$13 million                
(2019 – US$4 million) in Mexico, which expire from 2024 to 2030.

TC Energy recorded an income tax valuation allowance of $243 million and $673 million against the deferred income tax asset 
balances at December 31, 2020 and 2019, respectively. The decrease in the valuation allowance in 2020 is primarily a result of 
the foreign exchange movement on unrecognized capital losses, realized capital gains and valuation allowance releases. At each 
reporting date, the Company considers new evidence, both positive and negative, that could affect its view of the future 
realization of deferred tax assets. As at December 31, 2020, the Company determined there was sufficient positive evidence to 
conclude that it is more likely than not that the net deferred tax assets will be realized.

The Company recorded $400 million in valuation allowance releases in 2020 primarily a result of the final investment decision to 
proceed with the construction of the Keystone XL pipeline, the sale of the Ontario natural gas-fired power plants and the sale of 
a 65 per cent equity interest in Coastal GasLink LP. Refer to Note 27, Acquisitions and dispositions, for additional information on 
the sale of the Ontario natural gas-fired power plants and Coastal GasLink LP equity sale, and refer to Note 30, Subsequent 
events, for additional information on the Keystone XL pipeline.

Unremitted Earnings of Foreign Investments
Income taxes have not been provided on the unremitted earnings of foreign investments that the Company does not intend to 
repatriate in the foreseeable future. Deferred income tax liabilities would have increased at December 31, 2020 by approximately 
$684 million (2019 – $648 million) if there had been a provision for these taxes.

Income Tax Payments
Income tax payments of $252 million, net of refunds, were made in 2020 (2019 – payments, net of refunds, of $713 million; 
2018 – payments, net of refunds, of $338 million).

Subject to the results of audit examinations by taxing authorities and other legislative amendments, TC Energy does not 
anticipate further adjustments to the unrecognized tax benefits during the next 12 months that would have a material impact on 
its financial statements.

TC Energy and its subsidiaries are subject to either Canadian federal and provincial income tax, U.S. federal, state and local 
income tax or the relevant income tax in other international jurisdictions. The Company has substantially concluded all Canadian 
federal and provincial income tax matters for the years through 2012. Substantially all material U.S. federal, state and local 
income tax matters have been concluded for years through 2014. Substantially all material Mexico income tax matters have been 
concluded for years through 2013.

TC Energy's practice is to recognize interest and penalties related to income tax uncertainties in Income tax expense. Income tax 
expense for the year ended December 31, 2020 reflects $4 million of interest expense (2019 – $4 million of interest expense;            
2018 – $1 million of interest recovery). At December 31, 2020, the Company had accrued $11 million in interest expense        
(December 31, 2019 – $7 million). The Company incurred no penalties associated with income tax uncertainties related to Income 
tax expense for the years ended December 31, 2020, 2019 and 2018 and no penalties were accrued as at December 31, 2020 and 
2019.

U.S. Tax Reform and FERC Actions
In 2017, U.S. Tax Reform was signed into law and the enacted U.S. federal corporate income tax rate was reduced from               
35 per cent to 21 per cent effective January 1, 2018. This resulted in a remeasurement of existing deferred income tax assets and 
deferred income tax liabilities related to the Company's U.S. businesses to reflect the new lower income tax rate as at               
December 31, 2017. Given the significance of the legislation, SEC registrants were allowed to record provisional amounts at             
December 31, 2017 which could be adjusted as additional information became available, prepared or analyzed for a period not to 
exceed one year. The Company recognized further adjustments to the provisional amount in 2018. 

In accordance with FERC Form 501-G and uncontested rate settlement filings, the ADIT balances for all pipelines held wholly or in 
part by TC PipeLines, LP were eliminated from their respective rate bases. As a result, net regulatory liabilities recorded for these 
assets pursuant to U.S. Tax Reform were written off, resulting in a further deferred income tax recovery of $115 million in 2018.

Under U.S. Tax Reform, the U.S. Treasury and the U.S. Internal Revenue Service issued final base erosion and anti-abuse tax 
regulations in 2019 and final anti-hybrid rules on April 7, 2020. The finalization of these regulations did not have a material 
impact on the Company's consolidated financial statements at December 31, 2020.

Mexico Tax Reform
In 2019, Mexico passed tax reform legislation related to, among other things, interest deductibility and tax reporting. These 
changes did not have a material impact on the Company's consolidated financial statements at December 31, 2020.

Alberta Rate Reduction
On December 9, 2020, the Government of Alberta enacted the reduction of the corporate income tax rate to eight per cent 
effective July 1, 2020. This change did not have a material impact on the Company's consolidated financial statements at 
December 31, 2020.

Interest rates are the effective interest rates except for those pertaining to long-term debt issued for the Company's Canadian regulated natural gas operations, 
in which case the weighted average interest rate is presented as approved by the regulators. The effective interest rate is calculated by discounting the 
expected future interest payments, adjusted for loan fees, premiums and discounts. Weighted average and effective interest rates are stated as at the 
respective outstanding dates.
Certain subsidiaries of Columbia have guaranteed the principal payments of Columbia’s senior unsecured notes. Each guarantor of Columbia's obligations is 
required to comply with covenants under the debt indenture and in the event of default, the guarantors would be obligated to pay the principal and related 
interest.
The fair value adjustments include $167 million (2019 – $193 million) related to the acquisition of Columbia. In 2019, these adjustments also included an increase 
of $1 million related to hedged interest rate risk. Refer to Note 25, Risk management and financial instruments, for additional information.

Principal Repayments
At December 31, 2020, principal repayments for the next five years on the Company's long-term debt are approximately as

The effective interest rate is calculated by discounting the expected future interest payments using the coupon rate and any estimated future rate resets, 

adjusted for issue costs and discounts.

Junior subordinated notes of US$1 billion were issued in 2007 at a fixed rate of 6.35 per cent and converted in 2017 to a floating interest rate that is reset 
quarterly to the three-month LIBOR plus 2.21 per cent. 
The Junior subordinated notes were issued to TransCanada Trust, a financing trust subsidiary wholly owned by TCPL. While the obligations of TransCanada Trust 
are fully and unconditionally guaranteed by TCPL on a subordinated basis, the Trust is not consolidated in TC Energy's financial statements since TCPL does not 
have a variable interest in the Trust and the only substantive assets of the Trust are junior subordinated notes of TCPL.
The coupon rate is initially a fixed interest rate for the first 10 years and converts to a floating rate thereafter.

The Junior subordinated notes are subordinated in right of payment to existing and future senior indebtedness or other 
obligations of TCPL. 

In September 2019, TransCanada Trust (the Trust) issued US$1.1 billion of Trust Notes – Series 2019-A to investors with a fixed 
interest rate of 5.50 per cent for the first 10 years converting to a floating rate thereafter. All of the proceeds of the issuance by 
the Trust were loaned to TCPL for US$1.1 billion of junior subordinated notes of TCPL at an initial fixed rate of 5.75 per cent, 
including a 0.25 per cent administration charge. The rate will reset commencing September 2029 until September 2049 to the 
then three-month LIBOR plus 4.404 per cent per annum; from September 2049 until September 2079, the interest rate will reset 
to the then three-month LIBOR plus 5.154 per cent per annum. Refer to Note 25, Risk management and financial instruments, for 
additional information regarding the expected impact to the Company with certain rate settings of LIBOR which may cease to be 
published at the end of 2021 with full cessation expected by mid-2023. The junior subordinated notes are callable at TCPL's 
option at any time on or after September 15, 2029 at 100 per cent of the principal amount plus accrued and unpaid interest to 
the date of redemption.

Pursuant to the terms of the notes issued between the Trust and TCPL (the Trust Notes) and related agreements, in certain 
circumstances (1) TCPL may issue deferral preferred shares to holders of the Trust Notes in lieu of interest; and (2) TC Energy and 
TCPL would be prohibited from declaring or paying dividends on or redeeming their outstanding preferred shares (or, if none are 
outstanding, their respective common shares) until all deferral preferred shares are redeemed by TCPL. The Trust Notes may also 
be automatically exchanged for preferred shares of TCPL upon certain kinds of bankruptcy and insolvency events. All of these 
preferred shares would rank equally with any other outstanding first preferred shares of TCPL.

20.  REDEEMABLE NON-CONTROLLING INTEREST AND NON-CONTROLLING INTERESTS

Redeemable Non-Controlling Interest
On March 31, 2020, TC Energy announced that it would proceed with construction of the Keystone XL pipeline. As part of the 
funding plan, the Government of Alberta agreed to invest up to US$1.1 billion as equity in certain Keystone XL subsidiaries of       
TC Energy. In the year ended December 31, 2020, the Government of Alberta invested $1,033 million in the form of Class A 
Interests which rank above TC Energy's equity investment in Keystone XL and have certain voting rights.

TC Energy has a call right exercisable at any time to repurchase the Class A Interests from the Government of Alberta. In turn, the 
Government of Alberta has a put right to sell its Class A Interests to the Company exercisable upon and following the in-service 
date of the Keystone XL pipeline if certain conditions are met. As a result of these redemption features, the Company classified 
the Class A Interests as Redeemable non-controlling interest in mezzanine equity on the Consolidated balance sheet. These    
Class A Interests are entitled to a return in accordance with contractual terms. This return accrues on a quarterly basis and 
adjusts the carrying value of the Class A Interests accordingly. Refer to Note 30, Subsequent events, for additional information. 

At December 31, 2020, TC Energy had reclassified $630 million related to Class A Interests to Current liabilities on the 
Consolidated balance sheet to reflect the expectation that the Company would exercise its call right in January 2021 in 
accordance with contractual terms. Redeemable non-controlling interest in Current liabilities of $633 million also included         
$3 million of return accrued that was recorded in Interest expense in the Consolidated statement of income.

On January 4, 2021, the Company put in place a US$4.1 billion project-level credit facility to support construction of the  
Keystone XL pipeline, that is fully guaranteed by the Government of Alberta and non-recourse to the Company. The Company 
drew US$579 million on the credit facility on January 8, 2021, of which US$497 million was used to repurchase a majority of the 
Government of Alberta’s Class A Interests. The facility bears interest at a floating rate and matures in January 2024. 

The changes in Redeemable non-controlling interest classified in mezzanine equity were as follows:

Common Shares Issued and Outstanding
The Company is authorized to issue an unlimited number of common shares without par value. 

TC Energy Corporation At-the-Market Equity Issuance Program
In June 2017, the Company established an At-the-Market Equity Issuance Program (ATM program) that allowed, from time to 
time, for the issuance of common shares from treasury at the prevailing market price when sold through the Toronto Stock 
Exchange, the New York Stock Exchange or any other existing trading market for TC Energy common shares in Canada or the 
United States. This ATM program was effective for a 25-month period and was utilized as appropriate to assist in managing the 
Company's capital structure. Under the initial ATM program, the Company could issue up to $1.0 billion in common shares or the 
U.S. dollar equivalent. In June 2018, the Company replenished the capacity available under the program which allowed for the 
issuance of additional common shares from treasury up to $1.0 billion for a revised aggregate total of $2.0 billion or the            
U.S. dollar equivalent.

In 2018, 20 million common shares were issued under the above ATM program at an average price of $56.13 per share for 
proceeds of $1.1 billion, net of approximately $10 million of related commissions and fees. In July 2019, this ATM program expired 
with no common shares issued under it in 2019.

On December 7, 2020, the Company established a new ATM program that allows for the issuance of up to $1.0 billion in common 
shares or the U.S. dollar equivalent under substantially similar terms and trading platforms. This ATM program is effective for a 
25-month period and will be utilized as appropriate to assist in managing the Company's capital structure. No common shares 
were issued under this program in 2020.

Dividend Reinvestment and Share Purchase Plan
Under the Company's Dividend Reinvestment and Share Purchase Plan (DRP), eligible holders of common and preferred shares of 
TC Energy can reinvest their dividends and make optional cash payments to obtain additional TC Energy common shares. From  
July 1, 2016 to October 31, 2019, common shares under the DRP were issued from treasury at a two per cent discount to market 
prices over a specified period. 

Commencing with the dividends declared October 31, 2019, common shares purchased with reinvested cash dividends under the 
Company's DRP are acquired on the open market at 100 per cent of the weighted average purchase price. 

Basic and Diluted Net Income per Common Share
Net income per common share is calculated by dividing Net income attributable to common shares by the weighted average 
number of common shares outstanding. The weighted average number of shares for the diluted earnings per share calculation 
includes options exercisable under TC Energy's Stock Option Plan and shares issuable under the DRP up to October 31, 2019 when 
participation was satisfied with common shares issued from treasury.

At December 31, 2020, an additional 6,396,168 common shares were reserved for future issuance from treasury under                  
TC Energy's Stock Option Plan. The contractual life of options granted is seven years. Options may be exercised at a price 
determined at the time the option is awarded and vest equally on the anniversary date in each of the three years following the 
award. Forfeiture of stock options results from their expiration and, if not previously vested, upon resignation or termination of 
the option holder's employment. 

The Company used a binomial model for determining the fair value of options granted applying the following weighted average 
assumptions:

The amount expensed for stock options, with a corresponding increase in Additional paid-in capital, was $12 million in 2020     
(2019 – $13 million; 2018 – $13 million). At December 31, 2020, unrecognized compensation costs related to non-vested stock 
options were $14 million. The cost is expected to be fully recognized over a weighted average period of 1.7 years.

Shareholder Rights Plan
TC Energy's Shareholder Rights Plan is designed to provide the Board of Directors with sufficient time to explore and develop 
alternatives for maximizing shareholder value in the event of a takeover offer for the Company and to encourage the fair 
treatment of shareholders in connection with any such offer. Attached to each common share is one right that, under certain 
circumstances, entitles certain holders to purchase an additional common share of the Company.

All amounts are net of tax. Amounts in parentheses indicate losses recorded to OCI.
In 2020, other comprehensive (loss)/ income before reclassifications on currency translation adjustments, cash flow hedges and equity investments are net of 
non-controlling interest losses of $30 million (2019 – $85 million losses; 2018 – $166 million gains), losses of $16 million (2019 – $13 million losses;                        
2018 – $1 million losses) and gains of $1 million (2019 – $1 million losses; 2018 – nil), respectively.
Losses related to cash flow hedges reported in AOCI and expected to be reclassified to net income in the next 12 months are estimated to be $37 million            
($28 million, net of tax) at December 31, 2020. These estimates assume constant commodity prices, interest rates and foreign exchange rates over time, 
however, the amounts reclassified will vary based on the actual value of these factors at the date of settlement.

24.  EMPLOYEE POST-RETIREMENT BENEFITS 

The Company sponsors DB Plans for certain of its employees. Pension benefits provided under the DB Plans are generally based 
on years of service and highest average earnings over three consecutive years of employment. Effective January 1, 2019, there 
were certain amendments made to the Canadian DB Plan for new members whereby, subsequent to that date, benefits provided 
for these new members are based on years of service and highest average earnings over five consecutive years of employment. 
Upon commencement of retirement, pension benefits in the Canadian DB Plan increase annually by a portion of the increase in 
the Consumer Price Index. The Company's U.S. DB Plan is closed to non-union new entrants and all non-union hires participate in 
the DC Plan. Net actuarial gains or losses are amortized out of AOCI over the EARSL of plan participants, which is approximately 
nine years at December 31, 2020 (2019 and 2018 – nine years).

The Company also provides its employees with savings plans in Canada and Mexico, DC Plans consisting of a 401(k) Plan in the 
U.S. and post-employment benefits other than pensions, including termination benefits and life insurance and medical benefits 
beyond those provided by government-sponsored plans. Net actuarial gains or losses for the plans are amortized out of AOCI 
over the EARSL of employees, which was approximately 11 years at December 31, 2020 (2019 – 11 years; 2018 – 12 years). In 2020, 
the Company expensed $58 million (2019 – $61 million; 2018 – $59 million) for the savings and DC Plans. 

Total cash contributions by the Company for employee post-retirement benefits were as follows:

Current Canadian pension legislation allows for partial funding of solvency requirements over a number of years through letters 
of credit in lieu of cash contributions, up to certain limits. As such, in addition to the cash contributions noted above, the 
Company provided a $13 million letter of credit to the Canadian DB Plan in 2020 (2019 – $12 million; 2018 – $17 million), resulting 
in a total of $302 million provided to the Canadian DB Plan under letters of credit at December 31, 2020.

The most recent actuarial valuation of the pension plans for funding purposes was as at January 1, 2020 and the next required 
valuation will be as at January 1, 2021.

In December 2018, the Company recorded a settlement resulting from lump sum payments made in 2018 to certain terminated  
non-union vested participants in the Company's U.S. DB Plan related to voluntary cash settlement options available to these 
participants. The impact of the settlement was determined using assumptions consistent with those employed at                
December 31, 2017. The settlement reduced the Company's U.S. DB Plan's unrealized actuarial losses by $4 million, which was 
included in OCI, and resulted in a settlement charge of $4 million which was recorded in net benefit costs in 2018. Effective 
December 1, 2018, the plan was amended to include this unlimited lump sum payment option for certain union employees who 
were not previously eligible.

The benefit obligation for the Company’s pension benefit plans represents the projected benefit obligation. The benefit obligation for the Company’s other     
post-retirement benefit plans represents the accumulated post-retirement benefit obligation.
Excludes a $13 million letter of credit provided to the Canadian DB Plan for funding purposes (2019 – $12 million).

The actuarial loss realized on the defined benefit plan obligation is primarily attributable to a decrease in the weighted average 
discount rate from 3.20 per cent in 2019 to 2.70 per cent in 2020.

The actuarial loss realized on the other post-retirement benefit plan obligation is primarily due to the decrease in the weighted 
average discount rate from 3.35 per cent in 2019 to 2.75 per cent in 2020. 

The amounts recognized on the Company's Consolidated balance sheet for its DB Plans and other post-retirement benefits plans

Pension plan assets are managed on a going concern basis, subject to legislative restrictions, and are diversified across asset 
classes to maximize returns at an acceptable level of risk. Asset mix strategies consider plan demographics and may include 
traditional equity and debt securities as well as alternative assets such as infrastructure, private equity, real estate and 
derivatives to diversify risk. Derivatives are not used for speculative purposes and the use of leveraged derivatives is prohibited.

All investments are measured at fair value using market prices. Where the fair value cannot be readily determined by reference 
to generally available price quotations, the fair value is determined by considering the discounted cash flows on a risk-adjusted 
basis and by comparison to similar assets which are publicly traded. In Level I, the fair value of assets is determined by reference 
to quoted prices in active markets for identical assets that the Company has the ability to access at the measurement date. In 
Level II, the fair value of assets is determined using valuation techniques such as option pricing models and extrapolation using 
significant inputs which are observable directly or indirectly. In Level III, the fair value of assets is determined using a market 
approach based on inputs that are unobservable and significant to the overall fair value measurement. 

The following table presents plan assets for DB Plans and other post-retirement benefits measured at fair value, which have been 
categorized into the three categories based on a fair value hierarchy. For additional information on the fair value hierarchy, refer

The rate used to discount pension and other post-retirement benefit plan obligations was developed based on a yield curve of 
primarily corporate AA bond yields at December 31, 2020. This yield curve is used to develop spot rates that vary based on the 
duration of the obligations. The estimated future cash flows for the pension and other post-retirement benefit obligations were 
matched to the corresponding rates on the spot rate curve to derive a weighted average discount rate.

The significant weighted average actuarial assumptions adopted in measuring the Company's benefit obligations were

The overall expected long-term rate of return on plan assets is based on historical and projected rates of return for the portfolio 
in aggregate and for each asset class in the portfolio. Assumed projected rates of return are selected after analyzing historical 
experience and estimating future levels and volatility of returns. Asset class benchmark returns, asset mix and anticipated benefit 
payments from plan assets are also considered in determining the overall expected rate of return. The discount rate is based on 
market interest rates of high-quality bonds that match the timing and benefits expected to be paid under each plan.

A 6.30 per cent weighted-average annual rate of increase in the per capita cost of covered health care benefits was assumed for 
2021 measurement purposes. The rate was assumed to decrease gradually to 4.80 per cent by 2028 and remain at this level 
thereafter.

25.  RISK MANAGEMENT AND FINANCIAL INSTRUMENTS

Risk Management Overview
TC Energy has exposure to market risk and counterparty credit risk, and has strategies, policies and limits in place to manage the 
impact of these risks on earnings, cash flows and, ultimately, shareholder value.

Risk management strategies, policies and limits are designed to ensure TC Energy's risks and related exposures are in line with 
the Company's business objectives and risk tolerance. Market risk and counterparty credit risk are managed within limits that are 
established by the Company's Board of Directors, implemented by senior management and monitored by the Company's risk 
management and internal audit groups. The Board of Directors' Audit Committee oversees how management monitors 
compliance with market risk and counterparty credit risk management policies and procedures and oversees management's 
review of the adequacy of the risk management framework. 

Market Risk
The Company constructs and invests in energy infrastructure projects, purchases and sells commodities, issues short-term and   
long-term debt, including amounts in foreign currencies, and invests in foreign operations. Certain of these activities expose the 
Company to market risk from changes in commodity prices, foreign exchange rates and interest rates, which may affect the 
Company's earnings and the value of its financial assets and liabilities. The Company assesses contracts used to manage market 
risk to determine whether all, or a portion, meets the definition of a derivative. 

Derivative contracts the Company uses to assist in managing exposure to market risk may include the following:
• Forwards and futures contracts – agreements to purchase or sell a specific financial instrument or commodity at a specified 

price and date in the future 

• Swaps – agreements between two parties to exchange streams of payments over time according to specified terms 
• Options – agreements that convey the right, but not the obligation of the purchaser to buy or sell a specific amount of a 

financial instrument or commodity at a fixed price, either at a fixed date or at any time within a specified period. 

Commodity price risk
The following strategies may be used to manage exposure to commodity price risk in the Company's non-regulated businesses: 
• in the Company's natural gas marketing business, TC Energy enters into natural gas transportation and storage contracts as 

well as natural gas purchase and sale agreements. The Company manages exposure on these contracts using financial 
instruments and hedging activities to offset market price volatility

• in the Company's liquids marketing business, TC Energy enters into pipeline and storage terminal capacity contracts as well as 

crude oil purchase and sale agreements. The Company fixes a portion of the exposure on these contracts by entering into 
financial instruments to manage variable price fluctuations that arise from physical liquids transactions

• in the Company's power generation business, TC Energy manages the exposure to fluctuating commodity prices through       

long-term contracts and hedging activities including selling and purchasing power and natural gas in forward markets

• in the Company's non-regulated natural gas storage business, TC Energy's exposure to seasonal natural gas price spreads is 

managed with a portfolio of third-party storage capacity contracts and through offsetting purchases and sales of natural gas in 
forward markets to lock in future positive margins.

In May 2019, TC Energy sold its remaining U.S. Power marketing contracts completing the divestiture of its U.S. Northeast power 
business which began in 2017, greatly reducing its exposure to electricity price risk.

Interest rate risk
TC Energy utilizes short-term and long-term debt to finance its operations which exposes the Company to interest rate risk.         
TC Energy typically pays fixed rates of interest on its long-term debt and floating rates on its commercial paper programs and 
amounts drawn on its credit facilities. A small portion of TC Energy's long-term debt bears interest at floating rates. In addition, 
the Company is exposed to interest rate risk on financial instruments and contractual obligations containing variable interest 
rate components. The Company actively manages its interest rate risk using interest rate derivatives.

Many of TC Energy's financial instruments and contractual obligations with variable rate components reference LIBOR, of which 
certain rate settings may cease to be published at the end of 2021 with full cessation expected by mid-2023. The Company 
continues to monitor developments and is preparing to address any necessary system and contractual changes while assessing 
the adoption of the standard market proposed reference rates.

TC Energy Consolidated Financial Statements 2020   |  175

Foreign exchange risk
TC Energy generates revenues and incurs expenses and capital expenditures that are denominated in currencies other than 
Canadian dollars. As a result, the Company's earnings and cash flows are exposed to currency fluctuations.

A significant portion of TC Energy's businesses generate earnings in U.S. dollars, but since the Company reports its financial 
results in Canadian dollars, changes in the value of the U.S. dollar against the Canadian dollar can affect its net income. As the 
Company's U.S. dollar-denominated operations continue to grow, this exposure increases. A portion of this risk is offset by 
interest expense on U.S. dollar-denominated debt. The balance of the exposure is actively managed on a rolling two-year basis 
using foreign exchange derivatives, however, the natural exposure beyond that period remains.

A small portion of the Company's Mexico Natural Gas Pipelines monetary assets and liabilities are peso-denominated, while the 
functional currency for our Mexico operations is U.S. dollars. These peso-denominated balances are revalued to U.S. dollars and, 
as a result, changes in the value of the Mexican peso against the U.S. dollar can affect the Company's net income. This exposure 
is managed using foreign exchange derivatives.

Net investment hedges
The Company hedges a portion of its net investment in foreign operations (on an after-tax basis) with U.S. dollar-denominated 
debt, cross-currency swaps and foreign exchange options. 

The fair values and notional amounts for the derivatives designated as a net investment hedge were as follows:

33,400 (US 25,700)

Counterparty Credit Risk
TC Energy's exposure to counterparty credit risk consists of its cash and cash equivalents, accounts receivable, available-for-sale 
assets, the fair value of derivative assets and loans receivable. 

The sustained impact of the COVID-19 pandemic and related global energy demand and supply disruption continues to 
contribute to market uncertainty impacting a number of TC Energy's customers. While the majority of the Company's credit 
exposure is to large creditworthy entities, TC Energy has increased its monitoring of and communication with those 
counterparties experiencing greater financial pressures due to recent market events. 

176  |   TC Energy Consolidated Financial Statements 2020

 
 
 
 
   
 
At times, the Company's counterparties may endure financial challenges resulting from commodity price and market volatility, 
economic instability and political or regulatory changes. In addition to actively monitoring these situations, there are a number 
of factors that reduce TC Energy's counterparty credit risk exposure in the event of default, including:
• contractual rights and remedies together with the utilization of contractually-based financial assurances
• current regulatory frameworks governing certain TC Energy operations
• competitive position of the Company's assets and the demand for the Company's services, and
• potential recovery of unpaid amounts through bankruptcy and similar proceedings.

The Company reviews financial assets carried at amortized cost for impairment using the lifetime expected loss of the financial 
asset at initial recognition and throughout the life of the financial asset. TC Energy uses historical credit loss and recovery data, 
adjusted for management's judgment regarding current economic and credit conditions, along with supportable forecasts to 
determine any impairment, which is recognized in Plant operating costs and other. At December 31, 2020 and 2019, there were 
no significant credit losses, no significant credit risk concentrations and no significant amounts past due or impaired. 

TC Energy has significant credit and performance exposure to financial institutions because they hold cash deposits and provide 
committed credit lines and letters of credit that help manage the Company's exposure to counterparties and provide liquidity in 
commodity, foreign exchange and interest rate derivative markets.

Fair Value of Non-Derivative Financial Instruments
Available-for-sale assets are recorded at fair value which is calculated using quoted market prices where available. Certain         
non-derivative financial instruments included in Cash and cash equivalents, Accounts receivable, Other current assets, Loan 
receivable from affiliate, Restricted investments, Other long-term assets, Notes payable, Accounts payable and other, 
Redeemable non-controlling interest, Dividends payable, Accrued interest and Other long-term liabilities have carrying amounts 
that approximate their fair value due to the nature of the item or the short time to maturity. Each of these instruments are 
classified in Level II of the fair value hierarchy, except for the Company's LMCI equity securities which are classified in Level I.

Credit risk has been taken into consideration when calculating the fair value of non-derivative financial instruments.

Balance Sheet Presentation of Non-Derivative Financial Instruments

Long-term debt is recorded at amortized cost, except for US$200 million at December 31, 2019 that was attributed to hedged risk and recorded at fair value. 
Net income in 2020 included unrealized losses of nil (2019 – losses of $3 million) for fair value adjustments attributable to the hedged interest rate risk 
associated with interest rate swap fair value hedging relationships on US$200 million of long-term debt that matured in March 2020 (2019 – US$200 million). 
There were no other unrealized gains or losses from fair value adjustments to the non-derivative financial instruments.

Gains and losses arising from changes in the fair value of LMCI restricted investments impact the subsequent amounts to be collected through tolls to cover 
future pipeline abandonment costs. As a result, the Company records these gains and losses as regulatory assets or liabilities.
Gains and losses on other restricted investments are included in Interest income and other in the Company's Consolidated statement of income.
Realized gains and losses on the sale of LMCI restricted investments are determined using the average cost basis.

Fair Value of Derivative Instruments
The fair value of foreign exchange and interest rate derivatives has been calculated using the income approach which uses       
year-end market rates and applies a discounted cash flow valuation model. The fair value of commodity derivatives has been 
calculated using quoted market prices where available. In the absence of quoted market prices, third-party broker quotes or 
other valuation techniques have been used. The fair value of options has been calculated using the Black-Scholes pricing model. 
Credit risk has been taken into consideration when calculating the fair value of derivative instruments. Unrealized gains and 
losses on derivative instruments are not necessarily representative of the amounts that will be realized on settlement.

In some cases, even though the derivatives are considered to be effective economic hedges, they do not meet the specific 
criteria for hedge accounting treatment or are not designated as a hedge and are accounted for at fair value with changes in fair 
value recorded in net income in the period of change. This may expose the Company to increased variability in reported earnings 
because the fair value of the derivative instruments can fluctuate significantly from period to period.

The recognition of gains and losses on derivatives for Canadian natural gas regulated pipeline exposures is determined through 
the regulatory process. Gains and losses arising from changes in the fair value of derivatives accounted for as part of RRA, 
including those that qualify for hedge accounting treatment, are expected to be recovered or refunded through the tolls 
charged by the Company. As a result, these gains and losses are deferred as regulatory assets or regulatory liabilities and are 
refunded to or collected from the ratepayers in subsequent years when the derivative settles.

The majority of derivative instruments held for trading have been entered into for risk management purposes and all are subject 
to the Company's risk management strategies, policies and limits. These include derivatives that have not been designated as 
hedges or do not qualify for hedge accounting treatment but have been entered into as economic hedges to manage the 
Company's exposures to market risk.

Offsetting of derivative instruments
The Company enters into derivative contracts with the right to offset in the normal course of business as well as in the event of 
default. TC Energy has no master netting agreements, however, similar contracts are entered into containing rights to offset. 
The Company has elected to present the fair value of derivative instruments with the right to offset on a gross basis on the 
Consolidated balance sheet. The following tables show the impact on the presentation of the fair value of derivative instrument 
assets and liabilities had the Company elected to present these contracts on a net basis:

Amounts available for offset do not include cash collateral pledged or received.

With respect to the derivative instruments presented above, the Company provided cash collateral of $54 million and letters of 
credit of $15 million at December 31, 2020 (2019 – $58 million and $25 million, respectively) to its counterparties. At    
December 31, 2020, the Company held no cash collateral and no letters of credit (2019 – nil and nil, respectively) from 
counterparties on asset exposures.

Credit-risk-related contingent features of derivative instruments
Derivative contracts entered into to manage market risk often contain financial assurance provisions that allow parties to the 
contracts to manage credit risk. These provisions may require collateral to be provided if a credit-risk-related contingent event 
occurs, such as a downgrade in the Company's credit rating to non-investment grade. The Company may also need to provide 
collateral if the fair value of its derivative financial instruments exceeds pre-defined exposure limits.

Based on contracts in place and market prices at December 31, 2020, the aggregate fair value of all derivative instruments with 
credit-risk-related contingent features that were in a net liability position was $4 million (2019 – $4 million), for which the 
Company has provided no collateral in the normal course of business. If the credit-risk-related contingent features in these 
agreements were triggered on December 31, 2020, the Company would have been required to provide collateral equal to the fair 
value of the related derivative instruments discussed above. Collateral may also need to be provided should the fair value of 
derivative instruments exceed pre-defined contractual exposure limit thresholds.

The Company has sufficient liquidity in the form of cash and undrawn committed revolving credit facilities to meet these 
contingent obligations should they arise.

Fair Value Hierarchy
The Company's financial assets and liabilities recorded at fair value have been categorized into three categories based on a fair 
value hierarchy.

Levels

Level I

Level II

How fair value has been determined

Quoted prices in active markets for identical assets and liabilities that the Company has the ability to access at 
the measurement date. An active market is a market in which frequency and volume of transactions provides 
pricing information on an ongoing basis. 

This category includes interest rate and foreign exchange derivative assets and liabilities where fair value is 
determined using the income approach and commodity derivatives where fair value is determined using the 
market approach.

Inputs include published exchange rates, interest rates, interest rate swap curves, yield curves and broker 
quotes from external data service providers.

Level III

This category mainly includes long-dated commodity transactions in certain markets where liquidity is low and 
the Company uses the most observable inputs available or, if not available, long-term broker quotes to 
estimate the fair value for these transactions.

There is uncertainty caused by using unobservable market data which may not accurately reflect possible 
future changes in fair value.

The fair value of the Company's derivative assets and liabilities measured on a recurring basis, including both current and          
non-current portions, were categorized as follows:

27.  ACQUISITIONS AND DISPOSITIONS

Canadian Natural Gas Pipelines

Coastal GasLink LP
On May 22, 2020, TC Energy completed the sale of a 65 per cent equity interest in Coastal GasLink LP to third parties for net 
proceeds of $656 million before post-closing adjustments resulting in a pre-tax gain of $364 million ($402 million after tax). The 
pre-tax gain includes $231 million related to the required remeasurement of the Company’s retained 35 per cent equity interest 
to fair value which was based on the proceeds realized for the 65 per cent equity interest, and also incorporates the 
reclassification from AOCI to income of the fair value of a derivative instrument used to hedge the interest rate risk associated 
with project-level financing for the Coastal GasLink construction. The $402 million after-tax gain also reflects the utilization of 
previously unrecognized tax loss benefits. The pre-tax gain is included in Net (loss)/ gain on assets sold/held for sale in the 
Consolidated statement of income. As part of this transaction, TC Energy has been contracted by Coastal GasLink LP to construct 
and operate the pipeline. TC Energy uses the equity method to account for its remaining 35 per cent equity interest in the 
Company's consolidated financial statements. 

In conjunction with the equity sale, Coastal GasLink LP entered into secured long-term project financing credit facilities with a 
current total capacity of $6.8 billion to fund the majority of the construction costs of Coastal GasLink. Immediately preceding the 
equity sale, Coastal GasLink LP drew down $1.6 billion on the facilities, of which approximately $1.5 billion was paid to                 
TC Energy.

Along with this sale, TC Energy has provided an opportunity to the 20 First Nations that have executed agreements with     
Coastal GasLink LP to invest in the project through an option to acquire a 10 per cent equity interest.

U.S. Natural Gas Pipelines

Columbia Midstream Assets
In August 2019, TC Energy completed the sale of certain Columbia Midstream assets to a third party for approximately              
US$1.3 billion before post-closing adjustments.

The Company recorded a pre-tax gain on sale of $21 million ($152 million after-tax loss) including the impact of $4 million of 
foreign currency translation gains that were reclassified from AOCI to net income and the release of $595 million of Columbia 
goodwill allocated to these assets that is not deductible for income tax purposes. The pre-tax gain is included in Net (loss)/ gain 
on assets sold/held for sale in the Consolidated statement of income. This sale did not include any interest in Columbia Energy 
Ventures Company, the Company's minerals business in the Appalachian basin.

In 2020, upon finalizing its 2019 annual tax returns for its U.S. operations, the Company recorded an $18 million income tax 
recovery related to the sale.

Columbia Pipeline Group, Inc. 
At the time of the July 2016 acquisition of Columbia, certain Columbia shareholders dissented from the transaction and did not 
tender their shares. In October 2019, TC Energy made a payment to the dissenting Columbia shareholders in the amount of 
$373 million (US$284 million), representing the appraised value of their shares pursuant to a court decision, which affirmed the 
original Columbia share purchase price of US$25.50 per share plus accrued interest.

Liquids Pipelines

Northern Courier
In July 2019, TC Energy completed the sale of an 85 per cent equity interest in Northern Courier pipeline to a third party for gross 
proceeds of $144 million before post-closing adjustments resulting in a pre-tax gain of $69 million after recording the Company’s 
remaining 15 per cent interest at fair value. The pre-tax gain is included in Net (loss)/ gain on assets sold/held for sale in the 
Consolidated statement of income. On an after-tax basis, the gain of $115 million reflects the utilization of previously 
unrecognized tax loss benefits. Preceding the equity sale, Northern Courier pipeline issued $1.0 billion of long-term,                     
non-recourse debt with all proceeds paid to TC Energy.

TC Energy remains the operator of the Northern Courier pipeline and uses the equity method to account for its remaining            
15 per cent interest in the Company’s consolidated financial statements.

Power and Storage

TransCanada Turbines Ltd. 
On November 13, 2020, TC Energy acquired the remaining 50 per cent ownership interest in TransCanada Turbines Ltd.             
(TC Turbines) for cash consideration of US$67 million. TC Turbines provides industrial gas turbine maintenance, parts, repair and 
overhaul services. The acquisition was accounted for as a business combination and the evaluation of assigned fair value of 
acquired assets and liabilities did not result in recognition of goodwill. TC Energy previously accounted for its 50 per cent interest 
in TC Turbines as an equity investment but commenced full consolidation of TC Turbines as of the date of acquisition, which did 
not have a material impact on Revenues and Net income of the Company. In addition, the pro forma incremental impact on the 
Company’s Revenues and Net income for each of the periods presented was not material. 

Ontario natural gas-fired power plants
On April 29, 2020, the Company completed the sale of the Halton Hills and Napanee power plants as well as its 50 per cent 
interest in Portlands Energy Centre to a subsidiary of Ontario Power Generation Inc. for net proceeds of approximately 
$2.8 billion before post-closing adjustments. Pre-tax losses of $414 million ($283 million after tax) were recognized on the sale in 
2020 and reflect the finalization of post-closing obligations. The total pre-tax loss of $693 million ($477 million after tax) on this 
transaction includes losses accrued during 2019 while classified as an asset held for sale and the after-tax loss also reflects 
utilization of previously unrecognized tax loss benefits. The pre-tax loss is included in Net (loss)/ gain on assets sold/held for sale 
in the Consolidated statement of income. This loss may be amended in the future upon the settlement of existing insurance 
claims.

Coolidge Generating Station
In December 2018, the Company entered into an agreement to sell its Coolidge generating station in Arizona to SWG Coolidge 
Holdings, LLC (SWG). Salt River Project Agriculture Improvement and Power District (SRP), the PPA counterparty, subsequently 
exercised its contractual right of first refusal (ROFR) on a sale to a third party and the Company terminated the agreement with 
SWG.

In May 2019, the Company completed the sale to SRP, as per the terms of their ROFR, for proceeds of US$448 million before  
post-closing adjustments. As a result, the Company recorded a pre-tax gain on sale of $68 million ($54 million after tax) 
including the impact of $9 million of foreign currency translation gains which were reclassified from AOCI to net income. The 
pre-tax gain is included in Net (loss)/ gain on assets sold/held for sale in the Consolidated statement of income.

Cartier Wind
In October 2018, the Company completed the sale of its 62 per cent interest in the Cartier Wind power facilities to Innergex 
Renewable Energy Inc. for proceeds of $630 million before post-closing adjustments. As a result, the Company recorded a gain 
on sale of $170 million ($143 million after tax) which is included in Net (loss)/ gain on assets sold/held for sale in the Consolidated 
statement of income.

 28.  COMMITMENTS, CONTINGENCIES AND GUARANTEES

Commitments
TC Energy and its affiliates have long-term natural gas transportation and natural gas purchase arrangements as well as other 
purchase obligations, all of which are transacted at market prices and in the normal course of business. Purchases under these 
contracts in 2020 were $224 million (2019 – $236 million; 2018 – $207 million).

Capital expenditure commitments include obligations related to the construction of growth projects and are based on the 
projects proceeding as planned. Changes to these projects, including cancellation, would reduce or possibly eliminate these 
commitments as a result of cost mitigation efforts. At December 31, 2020, TC Energy had the following capital expenditure 
commitments:
• approximately $0.9 billion for its Canadian natural gas pipelines, primarily related to construction costs associated with     

NGTL System expansion projects

• approximately $0.3 billion for its U.S. natural gas pipelines, primarily related to construction costs associated with ANR and 

Columbia Gulf pipeline projects 

• approximately $0.2 billion for its Mexico natural gas pipelines, primarily related to construction of the Tula and Villa de Reyes  

pipeline projects

• approximately $0.9 billion for its Liquids pipelines, primarily related to the construction of Keystone XL
• approximately $0.3 billion for its Power and Storage business, primarily related to the Company's proportionate share of 

commitments for Bruce Power's life extension program.

Acquisition of common units of TC PipeLines, LP
On December 14, 2020, the Company entered into a definitive agreement and plan of merger to acquire all the outstanding 
common units of TC PipeLines, LP not beneficially owned by TC Energy or its affiliates in exchange for TC Energy common shares. 
Pursuant to the agreement, TC PipeLines, LP common unitholders will receive 0.70 common shares of TC Energy for each issued 
and outstanding publicly-held TC PipeLines, LP common unit. The exchange ratio reflects an equivalent of approximately 
38 million TC Energy common shares for all publicly-held common units of TC PipeLines, LP. A vote on the plan of merger by the 
unitholders of the publicly-held common units is scheduled for February 26, 2021. The transaction is expected to close in late first 
quarter 2021 subject to approval by the holders of a majority of outstanding common units of TC PipeLines, LP and customary 
regulatory approvals. 

If the transaction closes, the expected changes in the Company's ownership interest in TC PipeLines, LP will be accounted for as 
an equity transaction as the Company will continue to control TC PipeLines, LP and no gain or loss will be recognized in the 
Consolidated statement of income resulting from the transaction.

Contingencies
TC Energy is subject to laws and regulations governing environmental quality and pollution control. As at December 31, 2020, the 
Company had accrued approximately $24 million (2019 – $30 million) related to operating facilities, which represents the present 
value of the estimated future amount it expects to spend to remediate the sites. However, additional liabilities may be incurred 
as assessments take place and remediation efforts continue.

TC Energy and its subsidiaries are subject to various legal proceedings, arbitrations and actions arising in the normal course of 
business. The amounts involved in such proceedings are not reasonably estimable as the final outcome of such legal proceedings 
cannot be predicted with certainty. It is the opinion of management that the ultimate resolution of such proceedings and 
actions will not have a material impact on the Company's consolidated financial position or results of operations.

Guarantees
As part of its role as operator of the Northern Courier pipeline, TC Energy has guaranteed the financial performance of the 
pipeline related to delivery and terminalling of bitumen and diluent and contingent financial obligations under sub-lease 
agreements.

188  |   TC Energy Consolidated Financial Statements 2020

TC Energy and its partner on the Sur de Texas pipeline, IEnova, have jointly guaranteed the financial performance of the entity 
which owns the pipeline. Such agreements include a guarantee and a letter of credit which are primarily related to the delivery 
of natural gas.

TC Energy and its joint venture partner on Bruce Power, BPC Generation Infrastructure Trust, have each severally guaranteed 
certain contingent financial obligations of Bruce Power related to a lease agreement and contractor and supplier services. 

The Company and its partners in certain other jointly-owned entities have either (i) jointly and severally, (ii) jointly or                
(iii) severally guaranteed the financial performance of these entities. Such agreements include guarantees and letters of credit 
which are primarily related to construction services and the payment of liabilities. For certain of these entities, any payments 
made by TC Energy under these guarantees in excess of its ownership interest are to be reimbursed by its partners. 

The carrying value of these guarantees has been recorded in Accounts payable and other and Other long-term liabilities on the 
Consolidated balance sheet. Information regarding the Company’s guarantees were as follows:

29.  VARIABLE INTEREST ENTITIES

A 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 and losses of the entity. 

In the normal course of business, the Company consolidates VIEs in which it has a variable interest and for which it is considered 
to be the primary beneficiary. VIEs in which the Company has a variable interest but is not the primary beneficiary are considered  
non-consolidated VIEs and are accounted for as equity investments.

Consolidated VIEs
The Company's consolidated VIEs consist of legal entities where the Company is the primary beneficiary. As the primary 
beneficiary, the Company has the power, through voting or similar rights, to direct the activities of the VIE that most significantly 
impact economic performance including purchasing or selling significant assets; maintenance and operations of assets; incurring 
additional indebtedness; or determining the strategic operating direction of the entity. In addition, the Company has the 
obligation to absorb losses or the right to receive benefits from the consolidated VIE that could potentially be significant to the 
VIE. 

A significant portion of the Company’s assets are held through VIEs in which the Company holds a 100 per cent voting interest, 
the VIE meets the definition of a business and the VIE’s assets can be used for general corporate purposes. The consolidated VIEs 
whose assets cannot be used for purposes other than for the settlement of the VIE’s obligations, or are not considered a 
business, were as follows:

Certain consolidated VIEs have a redeemable non-controlling interest that ranks above the Company's equity interest. Refer to 
Note 20, Redeemable non-controlling interest and non-controlling interests and Note 30, Subsequent events, for additional 
information. 

Non-Consolidated VIEs
The Company’s non-consolidated VIEs consist of legal entities where the Company is not the primary beneficiary as it does not 
have the power to direct the activities that most significantly impact the economic performance of these VIEs or where this 
power is shared with third parties. The Company contributes capital to these VIEs and receives ownership interests that provide it 
with residual claims on assets after liabilities are paid. 

The carrying value of these VIEs and the maximum exposure to loss as a result of the Company's involvement with these VIEs

Columbia Pipeline Group, Inc. Debt Issuance
On December 9, 2020, the Company's subsidiary, Columbia, entered into a US$4.2 billion Delayed Draw Term Loan due in         
June 2022, bearing interest at a floating rate. In January 2021, US$4.0 billion was drawn on the Delayed Draw Term Loan and the 
total availability under the loan agreement was reduced accordingly.

Keystone XL Presidential Permit Revocation
On January 20, 2021, U.S. President Biden revoked the Presidential Permit for the Keystone XL pipeline. As a result and as of this 
date, the Company suspended the advancement of the Keystone XL pipeline project while it assesses the implications of the 
revocation and considers its options along with its partner, the Government of Alberta, and other stakeholders. The Company 
ceased capitalizing costs, including interest during construction, and also ceased accruing a return on the Government of Alberta 
Class A Interests, effective January 20, 2021. The decision to suspend advancement of the Keystone XL pipeline also represents a 
triggering event under GAAP requiring the Company to evaluate the Keystone XL capitalized project costs for impairment. Given 
the uncertainty related to the Keystone XL project, the Company expects to record a predominantly non-cash impairment charge 
in first quarter 2021. The carrying value of plant, property and equipment for Keystone XL, including capitalized interest, was 
$2.8 billion at December 31, 2020.

Accounting implications, in the first quarter of 2021 and beyond, will depend on the assessment and consideration of options as 
noted above, including the impacts that this has on contractual arrangements. As a result, the magnitude of the impairment 
charge and related recoveries cannot be quantified at this time.

The following factors will be considered in determining the amount and timing of the impairment charge and related recoveries, 
although these will be dependent on future decisions and developments: 
• the viability of projects currently associated with the Keystone XL pipeline, including Heartland Pipeline, TC Terminals and 
Keystone Hardisty Terminal, is also being reviewed. The carrying value of these projects in Other long-term assets on the 
Consolidated balance sheet at December 31, 2020 was $0.2 billion

• incremental liabilities incurred for contractual commitments
• specified contractual recoveries 
• recoverable value of the project's tangible assets
• income tax impact of the above items, including the assessment of any income tax valuation allowances and deferred income 

tax assets recorded at December 31, 2020.

Any principal outstanding under the project-level credit facility is fully guaranteed by the Government of Alberta without 
recourse to the Company. The suspension of the advancement of the project does not require immediate repayment of the debt 
as repayment is dependent upon certain other events or decisions specified in the credit facility agreement. While the credit 
facility remains outstanding, the Company continues to be responsible for ongoing interest charges. For further discussion of 
subsequent events related to the project-level credit facility, refer to Note 20, Redeemable non-controlling interest and           
non-controlling interests.
