AltaGas Business Overview and Organization

AltaGas is a leading North American energy infrastructure company that connects natural gas and natural gas liquids (NGLs) 

to domestic and global markets. The Company operates a diversified, low-risk, high-growth Utilities and Midstream business 

that is focused on delivering resilient and durable value for its stakeholders.

Within the Company’s Utilities segment, AltaGas owns and operates rate regulated Utilities assets that provide natural gas to 

1.7  million  end-users  across  five  U.S.  jurisdictions  (Virginia,  Maryland,  Michigan,  the  District  of  Columbia,  and Alaska).  The 

principal  focus  of  the  segment  is  to  provide  its  customers  with  safe,  reliable  and  affordable  energy  to  heat  and  power  their 

homes and places of work in order to carry out everyday life. The segment provides AltaGas with stable earnings and cash 

flow with approximately 70 percent of the Company’s Utilities customers being residential and the balance being commercial 

and industrial users. 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 2

 
 
 
Within AltaGas’ Midstream segment, the Company owns and operates a number of large energy infrastructure assets that are 

principally focused on: 1) gathering, processing, and fractionating raw natural gas production into pipeline quality natural gas 

and  NGLs;  and  2)  connecting  natural  gas  and  NGLs  to  domestic  and  global  downstream  markets.  This  includes  AltaGas 

operating  two  large  LPG  export  terminals  on  the  North  American  west  coast  that  ship  propane  and  butane  to  key  Asian 

markets.

The businesses of AltaGas are operated by the Company and a number of its subsidiaries including, without limitation, AltaGas 

Services  (U.S.)  Inc., AltaGas  Utility  Holdings  (U.S.)  Inc.,  WGL  Holdings,  Inc.  (WGL),  Wrangler  1  LLC,  Wrangler  SPE  LLC, 

Washington  Gas  Resources  Corporation,  WGL  Energy  Services,  Inc.  (WGL  Energy  Services),  and  SEMCO  Holding 

Corporation; in regard to the Utilities business, Washington Gas Light Company (Washington Gas), Hampshire Gas Company, 

and  SEMCO  Energy,  Inc.  (SEMCO);  in  regard  to  the  Midstream  business,  AltaGas  Extraction  and  Transmission  Limited 

Partnership,  AltaGas  Pipeline  Partnership,  AltaGas  Processing  Partnership,  AltaGas  Northwest  Processing  Limited 

Partnership,  Harmattan  Gas  Processing  Limited  Partnership,  Ridley  Island  LPG  Export  Limited  Partnership,  and  WGL 

Midstream Inc. (WGL Midstream); and, in regard to remaining assets in the Corporate/Other segment, AltaGas Power Holdings 

(U.S.)  Inc.,  WGL  Energy  Systems,  Inc.  (WGL  Energy  Systems),  and  Blythe  Energy  Inc.  (Blythe).  SEMCO  conducts  its 

Michigan natural gas distribution business under the name SEMCO Energy Gas Company (SEMCO Gas), its Alaska natural 

gas distribution business under the name ENSTAR Natural Gas Company (ENSTAR) and its 65 percent interest in an Alaska 

regulated  gas  storage  utility  under  the  name  Cook  Inlet  Natural  Gas  Storage  Alaska  LLC  (CINGSA).  Petrogas  Energy 

Corporation (Petrogas) was also added as a subsidiary of AltaGas upon the close of the acquisition on December 15, 2020.

Acquisition of Petrogas

On December 15, 2020, following the receipt of all required approvals, AltaGas acquired an additional 37 percent of Petrogas 

Energy Corp. (the Petrogas Acquisition) for total cash consideration upon close of approximately $715 million. Additional post-

acquisition  contingent  payments  of  up  to  $16  million  may  be  paid  no  later  than  2022  based  on  certain  criteria,  including 

earnings  targets  being  met. AltaGas  funded  the  transaction  through  draws  on  its  existing  credit  facilities. As  a  result  of  the 

transaction,  AltaGas'  ownership  in  Petrogas  has  increased  to  approximately  74  percent  with  Idemitsu  Kosan  Co.,  Ltd. 

(Idemitsu) owning the remaining approximately 26 percent. Subsequent to the transaction, AltaGas controls Petrogas and as 

such, Petrogas results have been consolidated for the period subsequent to close.

Petrogas Energy Corp. is a midstream and logistics company in North America with operations dating back to 1986. Petrogas 

operates  a  large  scale  fully  integrated  natural  gas  liquids  (NGLs)  and  crude  oil  platform  that  provides  sourcing,  storage, 

marketing, and transportation services for NGLs and LPGs to customers throughout Canada, the U.S. and Asia, and crude oil 

throughout Canada and the U.S.

Petrogas' business was principally underpinned by four primary business lines: 

▪

▪

▪

LPG Exports and Distribution: Comprised of the Ferndale LPG export facility and engages in the purchase, sale, 

and distribution of NGLs and LPGs throughout North America and Asia.

Domestic  Terminals:  Operates  various  North  American  storage  terminals  that  support  the  LPG  exports  and 

distribution  activities. This  business  line  also  enters  into  long-term  take-or-pay  contracts  for  management,  logistics, 

and optimization services.

Trucking  and  Liquids  Handling:  Provides  internal  and  third-party  trucking  services  in  Western  Canada  and  the 

Pacific Northwest. Includes hauling LPGs, crude, drilling fluids, and produced water.

▪ Wellsite  Fluids  and  Fuels:  Operates  two  production  facilities  focused  on  the  development  and  production  of 

proprietary drilling fluids, jet fuel, furnace fuel and heating oil.

AltaGas Ltd. – 2020 MD&A and Financial Statements - 3

The LPG Exports and Distribution and Domestic Terminals business lines are Petrogas' most significant assets and historically, 

have represented the vast majority of Petrogas' trailing normalized EBITDA.

The  Ferndale  terminal  is  an  LPG  export  facility  located  on  the  U.S.  west  coast  near  Ferndale,  Washington,  which  is 

approximately  100  miles  north  of  Seattle.  Shipping  times  to  Asia  average  approximately  11  days  using  Very  Large  Gas 

Carriers (VLGCs) from the facility and, as such, this origin has a similar structural shipping advantage as AltaGas' Ridley Island 

Propane Export Terminal (RIPET) facility compared to various LPG export terminals located on the U.S. Gulf Coast. Ferndale 

has refrigerated storage capacity, and is pipeline connected to local refineries. Similar to AltaGas' RIPET export facility, LPG 

export  volumes  being  shipped  from  Ferndale  are  delivered  into  various Asian  markets  and  provide  a  cleaner,  lower-carbon 

feedstock option for these key importing regions.

Petrogas'  Fort  Saskatchewan  rail  loading  and  truck  facility,  together  with  other  storage  facilities  in  Canada  and  the  U.S., 

expands AltaGas'  NGL  supply  sourcing  area  and  enhances  the  Company's  NGL  storage  and  logistics  capabilities.  With  the 

close of the acquisition, AltaGas now has access to a fleet of approximately 3,000 additional rail cars, five incremental rail and 

pipeline  connected  terminals,  and  approximately  6.3  million  barrels  of  additional  above  ground  and  cavern  storage.  Fort 

Saskatchewan  is  pipeline  connected  to  fractionation  facilities  and  to  multi-product  storage  facilities  in  Canada.  Petrogas' 

Canadian storage facilities, which are located in Fort Saskatchewan, Alberta, Sarnia, Ontario, and Strathcona, Alberta, have a 

combined capacity of approximately 4.8 million barrels of on-site storage handling for oil, propane, butane, and ethylene and 

are pipeline connected to refiners. Petrogas' largest U.S. storage and terminal facility, located in Indiana, has two underground 

storage  caverns  for  propane  and  butane. This  facility  is  situated  near  several  refineries,  tank  farms,  pipeline  connections  to 

area refiners and chemical facilities, and has inbound and outbound truck and rail capabilities.

▪

▪

On December 15, 2020, AltaGas closed the Petrogas Acquisition for total cash consideration of approximately $715 

million  and  additional  post-acquisition  contingent  payments  of  up  to  $16  million. AltaGas'  ownership  in  Petrogas  is 

now  approximately  74  percent  with  Idemitsu  Kosan  Co.,  Ltd.  indirectly  owning  the  remaining  approximately  26 

percent;

On August 21, 2020, the Canada Energy Regulator (CER) granted AltaGas an additional 25 year license to export up 

to  46,000  Bbls/d  of  propane  to  North  American  and  global  markets  from  RIPET,  bringing  the  aggregate  propane 

export capacity under 25 year export licenses to 92,000 Bbls/d. In December 2020, the Minister of Natural Resources 

approved the additional license; 

On February 14, 2020, WGL Midstream executed an Asset Management Agreement (AMA) with Consolidated Edison 

Company  of  New  York,  Inc.  (ConEd)  that  gives  ConEd  the  rights  to  use  WGL  Midstream’s  50,000  Dth  per  day  of 

transportation capacity on the MarketLink Expansion Project for the period from April 1, 2020 through April 1, 2035; 

and

On January 16, 2020, AltaGas received approval from the California Public Utilities Commission for the recontracting 

of the Blythe facility to Southern California Edison (SCE). Under the tolling agreement, SCE has exclusive rights to all 

capacity, energy, ancillary services, and resource adequacy benefits from August 1, 2020 to December 31, 2023.

Asset Sales Completed

In the third quarter of 2020, AltaGas closed the dispositions of AltaGas Pomona Energy Storage Inc. (Pomona) and 

land  related  to  a  battery  storage  facility,  as  well  as AltaGas  Ripon  Energy  Inc.  (Ripon),  a  small  natural  gas  power 

facility, both located in California. Aggregate gross proceeds for these dispositions, before working capital and other 

adjustments, were approximately $67 million, resulting in a pre-tax gain of $8 million.

Regulatory Developments 

▪

▪

▪

▪

On December 11, 2020, the PSC of DC approved a three-year US$150 million PROJECTpipes 2 plan for Washington 

Gas for the period from 2021 to 2023, and the associated surcharge recovery;

On August 28, 2020, Washington Gas filed a rate case in Maryland requesting US$28 million increase in base rates, 

including  US$6  million  currently  collected  through  the  Strategic  Infrastructure  Development  Enhancement  Plan 

(STRIDE)  surcharges  for  system  upgrades.  Evidentiary  hearings  took  place  between  January  7  and  January  11, 

2021. The Commission is expected to issue a final decision around the end of March 2021;

In April 2020, the Alaskan legislature passed legislation and the regulatory commissions of the District of Columbia, 

Maryland, Virginia, and Michigan issued orders allowing utilities to establish regulatory assets to record incremental 

COVID-19 related costs that will be evaluated for recovery in future proceedings; and

On January 13, 2020, Washington Gas filed a rate case in the District of Columbia requesting a US$35 million 

increase in base rates, including US$9 million of annual PROJECTpipes surcharges currently paid by customers for 

accelerated pipeline replacement. Washington Gas has also requested approval for a Revenue Normalization 

Adjustment mechanism to reduce customer bill fluctuations due to weather-related usage variations, similar to 

existing mechanisms in both Maryland and Virginia. On December 8, 2020, Washington Gas filed, for PSC of DC 

approval, a settlement agreement to resolve all issues in the case. Evidentiary hearings were suspended, and the 

PSC of DC held a public interest hearing on January 27, 2021 to address the settlement agreement. On February 24, 

2021, the PSC of DC approved the US$20 million base rate case recommended in the settlement agreement. The 

new rates will become effective on April 1, 2021.

Other Highlights 

▪

▪

▪

AltaGas continues to closely monitor developments related to COVID-19, including the existing and potential impact 

on  global  and  local  economies  in  the  jurisdictions  where  it  operates.  The  executive  team  and  cross-functional 

response  teams  that  were  established  in  late  January  continue  to  meet  regularly  to  align  response  strategy  and 

efforts within all areas of the Corporation. AltaGas' approach has been, and will continue to be, risk-based and guided 

by  its  core  values.  The  health  and  safety  of AltaGas'  employees,  customers,  contractors,  and  the  communities  in 

which it operates is the top priority and is integrated into each aspect of AltaGas' response efforts;

On April 1, 2020, AltaGas announced it would donate $1 million to help community partners in its operating regions 

respond  to  the  COVID-19  pandemic.  The  assistance  funds,  provided  by  AltaGas,  were  distributed  to  partner 

organizations on the front lines supporting local communities and providing critical support to our health care workers 

addressing the health crisis; 

In the first quarter of 2020, AltaGas revised its reportable segments to align with the structure of its business following 

asset  sales  completed  as  part  of  its  2019  asset  monetization  program. As  a  result  of  these  changes, AltaGas  has 

refocused on its core Utilities and Midstream segments. Consistent with Management’s strategic view of the business 

and  the  basis  on  which  it  assesses  performance  and  allocates  resources,  beginning  in  2020,  AltaGas  has  two 

operating  segments:  Utilities,  which  now  includes  the  WGL  retail  marketing  business,  and  Midstream.  These 

operating segments have not been aggregated in the determination of AltaGas' reportable segments. All other assets 

are included in the Corporate/Other segment. Prior period segment information has been restated to conform to the 

current reporting segment presentation;

On  January  9,  2020,  AltaGas  announced  the  appointment  of  two  new  independent  Directors,  Linda  Sullivan  and 

Nancy Tower, to its Board of Directors. In addition, AltaGas announced the retirement of Daryl Gilbert from the Board 

of Directors, which was effective following the conclusion of AltaGas' annual meeting of shareholders in May 2020;

In the third quarter of 2020, Painted Pony Energy Ltd. (Painted Pony), one of AltaGas' significant counterparties in the 

Northeast  British  Columbia  (NEBC)  region,  announced  that  it  had  entered  into  an  agreement  to  be  acquired  by 

Canadian  Natural  Resources  Limited.  The  shareholders  of  Painted  Pony  approved  the  plan  of  arrangement  on 

October  1,  2020,  and  the  transaction  was  completed  on  October  6,  2020.  In  addition,  in  the  third  quarter  of  2020, 

ConocoPhillips acquired oil and gas assets in the Inga/Fireweed/Stoddard division in the Montney area from another 

of  AltaGas'  counterparties,  Kelt  Exploration  Ltd.  All  operating  agreements  of  AltaGas  remain  in  effect.  These 

transactions resulted in a significant increase in the credit worthiness of AltaGas' counterparties in the NEBC region;

On  April  21,  2020,  SEMCO  completed  the  private  placement  of  US$450  million  of  first  mortgage  bonds,  in  two 

tranches of US$225 million each. One of the tranches has a term of ten years with a coupon rate of 2.45 percent, and 

the other has a term of 30 years with a coupon rate of 3.15 percent. The proceeds were used to repay debt drawn on 

credit facilities and the US$300 million notes that matured in April 2020;

On June 10, 2020, AltaGas completed the issuance of $500 million of senior unsecured medium term notes with a 

coupon  rate  of  2.157  percent,  maturing  on  June  10,  2025.  The  proceeds  were  used  to  pay  down  existing 

indebtedness under AltaGas' credit facilities and for general corporate purposes. Because the coupon rate is lower 

than the borrowing rate of the repaid debt, AltaGas expects cost savings of approximately $6 million per annum;

On September 30, 2020, 35,180 of the outstanding 5,511,220 Cumulative Redeemable Five-Year Fixed Rate Reset 

Preferred  Shares,  Series  A  (Series  A  Preferred  Shares)  were  converted  into  Cumulative  Floating  Rate  Preferred 

Shares, Series B (Series B Preferred Shares), and 1,270,639 of the outstanding 2,488,780 Series B Preferred Shares 

were  converted  into  Series  A  Preferred  Shares.  As  a  result  of  the  conversions,  AltaGas  has  6,746,679  Series  A 

Preferred Shares and 1,253,321 Series B Preferred Shares; 

On November 30, 2020, AltaGas completed the issuance of $500 million of senior unsecured medium term notes with 

a coupon rate of 2.075 percent, maturing on May 30, 2028, and $200 million of senior unsecured medium term notes 

with  a  coupon  rate  of  2.477  percent,  maturing  on  November  30,  2030.  The  net  proceeds  were  used  to  pay  down 

existing  indebtedness  under  AltaGas'  credit  facility,  to  fund  the  redemption  of  all  of  the  issued  and  outstanding 

Cumulative  Redeemable  5-Year  Minimum  Rate  Reset  Preferred  Shares,  Series  I  of  AltaGas,  and  for  general

million per year;

coupon rate of 3.65 percent due September 15, 2049; and

Highlights Subsequent to Year End

▪

On  February  2,  2021,  AltaGas  announced  the  appointment  of  a  new  Independent  Director,  Jon-Al  Duplantier,  to 

AltaGas'  Board  of  Directors,  effective  immediately.  AltaGas  also  announced  the  planned  retirement  of  Allan 

Edgeworth from AltaGas' Board of Directors effective upon the conclusion of AltaGas' next Annual General Meeting, 

to be held in late April 2021.

AltaGas' Vision, Mission, and Focus 

AltaGas’ Vision is to be a leading North American infrastructure company that connects natural gas and natural gas liquids to 

domestic and global markets. The Company’s Mission is to improve quality of life by safely and reliably connecting customers 

to  affordable  sources  of  energy  for  today  and  tomorrow.  To  advance  these  pursuits, AltaGas’  team  of  approximately  3,000 

people is guided by the Company's core values. These values form the foundations for how the Company treats each other, its 

customers,  its  Indigenous  partners  and  other  stakeholders,  and  serve  as  a  blueprint  for  a  sustainable  future. AltaGas  views 

access  to  reliable  and  affordable  energy  as  fundamental  in  the  pursuit  of  improved  quality  of  life,  reduced  physical  barriers, 

improved  access  to  education,  and  to  fuel  economic  expansion.  As  such,  the  Company  is  committed  to  its  foundational 

principals of maintaining safe and reliable operations, delivering the critical energy its customers need, and honoring the social 

and moral contract that AltaGas has with the communities it serves.

Core Strategy

AltaGas' long-term strategy is to build a diversified low-risk, high-growth Utilities and Midstream business that is focused on 

delivering resilient and durable value for our stakeholders. This includes a focus on providing the Company’s shareholders with 

regular returns of capital through dividend payments and the prospect for capital appreciation through steady and sustainable 

growth.

AltaGas' forward plan to regularly return capital is to deliver regular, sustainable, and annual dividend increases that compound 

in the years ahead and are supported by durable growth in earnings per share, declining leverage ratios, and reduced payout 

ratios. The Company’s growth is expected to be generated by optimizing AltaGas’ existing assets for appropriate returns and 

deploying new capital that is principally focused on organic expansion initiatives that are underpinned by meeting base return 

thresholds.

AltaGas  believes  that  its  current  asset  base  is  well-positioned  to  achieve  this  feat.  This  includes  operating  a  large  rate 

regulated  Utilities  platform  that  provides  stable  earnings  and  cash  flow  and  that  operates  across  a  diversified  geographic 

footing,  heavily  weighted  to  residential  usage.  The  Utilities  platform  also  provides  steady  growth  opportunities  focused  on 

Accelerated Pipeline Replacement Programs (ARPs) that replace aging infrastructure, reduce methane emissions through leak 

remediation,  and  improve  the  safety  and  reliability  of  the  delivery  of  affordable  energy.  This  also  includes  operating  a 

concentrated  and  modern  Midstream  platform  that AltaGas  views  as  being  well-positioned  for  where  the  market  is  heading 

over the next three to five years. This includes a significant footprint in the Montney in NEBC and LPG exports with the only 

two west coast terminals in North America.

In 2021, AltaGas plans to focus on progressing its long-term strategy of building a diversified Utilities and Midstream business 

designed to provide resilient and durable value for its stakeholders that compounds over the long-term. Specific 2021 strategic 

priorities include to:

Advance AltaGas'  operational  excellence  model  to  improve  business  processes  and  aggressively  manage  costs  to 

improve the customer experience and returns; 

Build  a  world  class  Midstream  and  energy  export  business  by  maximizing  the  utilization  of  existing  assets  and 

integrating and optimizing the Petrogas business to advance AltaGas' distinctive energy export strategy; and 

▪ Maintain a disciplined approach to capital allocation within a self-funding model that continues to de-lever the balance 
sheet  and  increase  financial  flexibility  over  time,  with  incremental  de-leveraging  opportunities  being  possible  from 

potential non-core asset sales. 

AltaGas’  Board  of  Directors  is  actively  engaged  in AltaGas’  strategy.  The  Corporation  continually  assesses  the  macro-  and 

micro-economic trends impacting the businesses and seeks opportunities to generate and protect value for its stakeholders. 

The opportunities AltaGas pursues must meet strategic, operating, and financial criteria to ensure they align with the long-term 

strategy and provide ongoing organic growth potential, favorable risk profiles, and strong risk-adjusted returns.

2021 Outlook

In  2021,  AltaGas  expects  to  achieve  annual  consolidated  normalized  EBITDA  of  approximately  $1.4  to  $1.5  billion,  and 

normalized earnings per share of approximately $1.45 to $1.55 per share assuming an effective tax rate of approximately 23 

percent.

The Utilities segment is expected to contribute approximately 60 percent of normalized EBITDA, with growth driven primarily 

by  revenue  growth  from  previously  settled  rate  cases,  increased  spend  on  accelerated  capital  programs,  the  impact  of 

Washington  Gas'  District  of  Columbia  rate  case  which  has  settled,  the  expected  impact  of  Maryland's  rate  case  which  is 

expected  to  be  completed  in  the  near-term,  ongoing  operational  cost  optimization  activities,  and  modest  customer  growth, 

partially  offset  by  the  one-time  favorable  impact  from  the  pension  accounting  change  in  2020.  Expected  growth  in  the 

Midstream segment, primarily driven by the integration and optimization of Petrogas operations, higher export volumes from 

RIPET, and increased volumes at NEBC facilities, is expected to be partially offset by lower commodity prices and the impacts 

of  a  blend  and  extend  contract  that  was  entered  into  in  2018  and  takes  effect  in  2021.  Midstream  segment  earnings  are 

approximately  60  percent  underpinned  through  take-or-pay,  cost-of-service,  and  fee-for-service  contracts  at  the  Midstream 

facilities and tolling agreements at the export facilities. Normalized EBITDA from the Corporate/Other segment, which includes 

AltaGas' remaining power assets, is expected to be lower in 2021 mainly due to asset sales completed in 2020 and recoveries 

related  to  the  Canada  Emergency  Wage  Subsidy  (CEWS)  in  2020.  Overall  growth  is  expected  to  offset  lost  normalized 

EBITDA from a full year impact of asset sales completed in 2020 and the impact of expected 2021 asset sales.

The  overall  forecasted  normalized  EBITDA  and  earnings  per  share  include  assumptions  around  the  U.S./Canadian  dollar 

exchange rate. The impact of the COVID-19 pandemic on AltaGas business segments is expected to be less pronounced than 

in  2020.  Within  each  segment,  the  performance  of  the  underlying  businesses  has  the  potential  to  vary. Any  variance  from 

AltaGas’  current  assumptions  could  impact  the  forecasted  normalized  EBITDA  and  normalized  earnings  per  share.  Please 

refer to the Risk Management section of this MD&A for further discussions of the risks to AltaGas arising from the COVID-19 

pandemic.

AltaGas  estimates  an  average  of  approximately  9,000  Bbls/d  of  NGLs  will  be  exposed  to  frac  spreads  prior  to  hedging 

activities. AltaGas  plans  to  manage  the  2021  frac  exposed  NGL  volumes  with  an  active  hedging  program  and  is  currently 

approximately 97 percent hedged for 2021. 

At  RIPET  and  Ferndale,  NGL  price  margins  are  protected  through AltaGas'  comprehensive  hedging  programs.  For  volumes 

not  contracted  under  tolling  arrangements  at  RIPET,  approximately  67  percent  are  currently  financially  hedged  at  an  FEI  to 

Mont  Belvieu  spread  of  approximately  US$10/Bbl.  At  Ferndale,  approximately  12  percent  of  exposed  propane  and  butane 

volumes  are  currently  hedged,  at  an  FEI  to  Conway  spread  of  approximately US$14/Bbl  for  propane  and  an  approximately 

US$28/Bbl FEI spread to butane purchase price. Collectively, approximately 60 percent of AltaGas' propane export volumes 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 8

 
are  hedged  for  2021. AltaGas  plans  to  manage  the  export  facilities  such  that  a  growing  portion  of  annual  capacity  will  be 

underpinned by tolling arrangements, and expects to reach this objective over the next several years. 

Sensitivity Analysis

AltaGas’ financial performance is affected by factors such as changes in commodity prices, exchange rates, and weather. The 

following table illustrates the approximate effect of these key variables on AltaGas’ expected normalized EBITDA for 2021:

The sensitivity is net of hedges currently in place. The impact on EBITDA due to changes in the spread will vary and is being managed through an active 

hedging program. 

Growth Capital

Based  on  projects  currently  under  review,  development,  or  construction,  AltaGas  expects  net  capital  expenditures  of 

approximately $910 million in 2021. The majority of capital expenditures are expected to focus on projects within the Utilities 

platform that are anticipated to deliver stable and transparent rate base growth and strong risk-adjusted returns. The Utilities 

segment is expected to account for approximately 80 to 85 percent of total capital expenditures, while the Midstream segment 

is expected to account for approximately 15 to 20 percent and the Corporate/Other segment is expected to account for any 

remainder. In 2021, AltaGas’ capital expenditures for the Utilities segment will focus primarily on accelerated pipe replacement 

programs,  customer  growth,  and  system  betterment.  In  the  Midstream  segment,  capital  expenditures  are  anticipated  to 

primarily relate to the construction of the Nig Creek expansion, maintenance and administrative capital, optimization of existing 

assets, and new business development. Maintenance capital related to Midstream assets and remaining power assets in the 

Corporate/Other  segment  is  expected  to  be  approximately  $45  to  $55  million  of  the  total  capital  expenditures  in  2021.  The 

Corporation  continues  to  focus  on  capital  efficient  organic  growth  and  disciplined  capital  allocation  while  improving  balance 

sheet strength and flexibility.

AltaGas' 2021 committed capital program is expected to be funded through internally-generated cash flow and normal course 

borrowings on existing committed credit facilities.

Utilities

Description of Assets 

AltaGas owns and operates utility assets that store and deliver natural gas to end-users in Virginia, Maryland, Michigan, the 

District of Columbia, and Alaska, serving approximately 1.7 million customers and with a combined rate base of approximately 

US$4.3 billion. 

The  utilities  are  underpinned  by  regulated  returns  and  regulatory  regimes  that  generally  provide  stable  earnings  and  cash 

flows. The Utilities segment enhances the diversification of AltaGas' portfolio of energy infrastructure assets and strengthens 

the Corporation’s business profile, thus allowing the Corporation to meet its objective of operating a diversified low-risk, high-

growth energy infrastructure business that is focused on delivering resilient and durable value for its stakeholders with long-life 

assets.

The Utilities segment includes: 

SEMCO Gas in Michigan; 

Hampshire, providing regulated interstate natural gas storage to Washington Gas; 

▪ Washington Gas in Virginia, Maryland, and the District of Columbia;
▪
▪
▪
▪
▪ WGL's Retail Marketing business, which sells power and natural gas directly to residential, commercial, and industrial 

A 65 percent interest in Cook Inlet Natural Gas Storage Alaska LLC (CINGSA) in Alaska; and

ENSTAR in Alaska; 

customers in Maryland, Virginia, Delaware, Pennsylvania, Ohio, and the District of Columbia.

AltaGas Ltd. – 2020 MD&A and Financial Statements - 12

All of AltaGas' regulated Utilities are allowed the opportunity to earn regulated returns. This return on rate base is composed of 

regulator-allowed  financing  costs  and  return  on  equity  (ROE).  If  actual  costs  are  different  from  those  recoverable  through 

approved rates, the utility bears the risk of this difference other than for certain costs that are subject to deferral treatment. 

Earnings in the Utilities segment are seasonal, as revenues are primarily based on the demand for space heating in the winter 

months, mainly from November to March. Costs, on the other hand, are generally incurred more uniformly over the year. This 

typically results in stronger first and fourth quarters and weaker second and third quarters. In Michigan, Alaska, and the District 

of Columbia, earnings can be impacted by variations from normal weather resulting in delivered gas volumes being different 

than  anticipated.  Increases  in  the  number  of  customers  or  changes  in  customer  usage  are  other  factors  that  might  typically 

affect delivered volumes, and hence actual earned returns for the Utilities segment. In Virginia and Maryland, Washington Gas 

has billing mechanisms in place which are designed to eliminate or mitigate the effects of variance in customer usage caused 

by weather and other factors such as conservation. 

Washington Gas

Washington Gas is a regulated public utility that has been engaged in the natural gas distribution business since 1848, and 

provides  regulated  gas  distribution  services  to  end  users  in  Virginia,  Maryland,  and  the  District  of  Columbia. At  the  end  of 

2020,  Washington  Gas  had  approximately  1.2  million  customers,  of  which  approximately  81  percent  were  residential.  The 

number  of  customers  at  Washington  Gas  increased  approximately 1  percent  in  2020. The  rate  base  at  December  31,  2020 

was  approximately  US$3.3  billion.  At  the  end  of  2020,  the  approved  regulated  ROE  for  Washington  Gas  in  its  various 

jurisdictions ranged from 9.2 - 9.7 percent based on an equity ratio ranging from 53.5 - 55.7 percent. 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 13

 
Washington Gas is regulated by the PSC of DC, the PSC of MD, and the SCC of VA, which approve its terms of service and 

the billing rates that it charges to customers. The rates charged to Utilities customers are designed to recover Washington Gas’ 

operating expenses and natural gas commodity costs and to provide a return on its investment in the net assets used in its firm 

gas sales and delivery service.

Washington  Gas  has  accelerated  pipe  replacement  programs  in  place  in  each  of  its  three  jurisdictions.  Washington  Gas 

accelerates pipe replacement in order to reduce risk and further enhance the safety and reliability of the pipeline system. Each 

regulatory commission having jurisdiction over Washington Gas’ retail rates has approved accelerated replacement programs 

with an associated surcharge mechanism to recover the cost, including a return, on those capital investments. In contrast to 

the traditional rate-making approach to capital investments, for the accelerated pipe replacement programs, Washington Gas 

is receiving recovery for these investments through the approved surcharges for each program and is authorized to invest in 

each of these programs over a three- to five-year period. 

Washington Gas’ customers are eligible to purchase their natural gas from unregulated third-party marketers through natural 

gas  unbundling. As  at  December  31,  2020,  approximately  15  percent  of  its  customers  have  chosen  to  purchase  gas  from 

marketers. This  does  not  negatively  impact  Washington  Gas’  net  income  as  the  Corporation  does  not  earn  a  margin  on  the 

sale of natural gas to firm customers, but only from the delivery and distribution of the gas. 

Washington  Gas  obtains  natural  gas  supplies  that  originate  from  multiple  regions  throughout  the  United  States.  At 

December  31,  2020,  it  had  service  agreements  with  five  pipeline  companies  that  provided  firm  transportation  and  storage 

services with contract expiration dates ranging from 2021 to 2039. Washington Gas has also contracted with various interstate 

pipeline and storage companies to add to its storage and transportation capacity. Washington Gas, under its asset optimization 

program,  makes  use  of  storage  and  transportation  capacity  resources  when  those  assets  are  not  required  to  serve  utility 

customers. The objective of this program is to derive a profit to be shared with its utility customers. These profits are earned by 

entering into commodity-related physical and financial contracts with third parties. 

Hampshire 

Hampshire  owns  underground  natural  gas  storage  facilities,  including  pipeline  delivery  facilities  located  in  and  around 

Hampshire  County,  West  Virginia,  and  operates  these  facilities  to  serve  Washington  Gas.  Hampshire  is  regulated  by  the 

FERC.  Washington  Gas  purchases  all  of  the  storage  services  of  Hampshire,  and  includes  the  cost  of  the  services  in  the 

commodity cost of its regulated energy bills to customers. Hampshire operates under a “pass-through” cost-of-service based 

tariff approved by FERC. 

SEMCO Gas

SEMCO owns and operates a regulated natural gas distribution utility in Michigan operating under the name SEMCO Gas and 

has  an  interest  in  a  regulated  natural  gas  storage  facility  in  Michigan. At  the  end  of 2020,  SEMCO  Gas  had  approximately 

313,000  customers.  Of  these  customers,  approximately  92  percent  are  residential.  In  2020,  SEMCO  Gas  experienced 

customer  growth  of  approximately  1  percent  reflecting  growth  in  the  franchise  areas  and  customer  conversions  with  the 

favorable  price  of  natural  gas  compared  to  other  heating  sources.  The  rate  base  at  year  end  was  approximately  US$719 

million. In 2020, the approved regulated ROE for SEMCO Gas was 9.87 percent with an approved capital structure based on 

45.86 percent equity. 

SEMCO Gas is regulated by the MPSC. It operates under cost-of-service regulation and utilizes actual results from the most 

recently completed fiscal year along with known and measurable changes in its application for new rates. 

SEMCO  Gas  has  an  Accelerated  MRP  surcharge  to  recover  a  stated  amount  of  accelerated  main  replacement  capital 

expenditures in excess of what is authorized in its current base rates. The MRP began in 2011, was expanded in 2013 and 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 14

renewed for an additional five years in 2015.  A new MRP was approved as part of the 2019 rate case. For the years 2021 to 

2025  the  anticipated  annual  average  capital  spending  is  approximately  US$12  million.  Any  MRP  revenue  associated  with 

unspent  capital  will  be  placed  into  a  regulatory  liability  account  to  be  addressed  in  the  next  general  rate  base  case. 

Additionally,  a  new  IRIP  was  approved  in  the  2019  rate  case,  pursuant  to  which  SEMCO  Gas  will  complete  certain  projects 

totaling US$55 million to improve the reliability of infrastructure. Customers will be billed a surcharge beginning in 2021 for the 

IRIP. 

ENSTAR and CINGSA

SEMCO owns and operates a regulated natural gas distribution utility in Alaska under the name ENSTAR. SEMCO, through a 

subsidiary,  holds  a  65  percent  interest  in  CINGSA,  a  regulated  natural  gas  storage  utility  in  Alaska.  At  the  end  of  2020, 

ENSTAR had approximately 149,000 customers including residential, commercial, and transportation, and of these customers, 

approximately 91 percent are residential. In 2020, ENSTAR experienced customer growth of approximately 1 percent reflecting 

growth  in  the  franchise  areas  and  customer  conversions  with  the  favorable  price  of  natural  gas  compared  to  other  heating 

sources. The rate base at year end was approximately US$256 million for ENSTAR and US$66 million for CINGSA (SEMCO's 

65 percent share). 

ENSTAR  and  CINGSA  are  regulated  by  the  Regulatory  Commission  of  Alaska  (RCA)  and  operate  under  cost-of-service 

regulation utilizing actual results from the most recently completed fiscal year along with known and measurable changes in 

their application for new rates.

Retail Energy Marketing 

The  U.S.  retail  gas  marketing  business  sells  natural  gas  directly  to  residential,  commercial,  and  industrial  customers  in 

Maryland, Virginia, Delaware, Pennsylvania, and the District of Columbia. 

The U.S. retail power marketing business sells power to end users in Maryland, Delaware, Pennsylvania, Ohio, and the District 

of Columbia. This area is served by the PJM Interconnection (PJM), a regional transmission organization that regulates and 

coordinates generation supply and the wholesale delivery of electricity in these states and jurisdictions.

Natural gas and electricity are purchased with the objective of earning a profit through competitively priced sales contracts with 

end users. Requirements to serve retail customers is closely matched with commitments for deliveries, and thus, a secured 

supply arrangement expiring in 2022 has been entered into with Shell Energy North America (US), L.P, which reduces credit 

requirements.

▪ Maintain strong relationships with local communities, Indigenous peoples, governments, and regulatory bodies; and
▪ Maintain strong community and regulatory relationships while ensuring appropriate returns to shareholders.

AltaGas expects to grow its existing utility infrastructure through continued investment and capital improvements in franchise 

areas,  which  will  result  in  rate  base  growth  and  continued  customer  growth  including  the  conversion  of  users  of  alternative 

energy sources to natural gas. AltaGas' utilities have had annual rate base growth averaging approximately 74 percent over 

the  past  three  years  including  the  addition  of  WGL’s  rate  base  and  after  adjusting  for  the  impact  of  foreign  exchange 

translation. The growth in rate base is a direct result of the WGL Acquisition in 2018, prudent investments in current areas of 

operations,  and  the  addition  of  new  customers.  Customer  growth  rates  for AltaGas’  utilities  are  moderate,  as  is  typical  with 

mature utilities, with growth rates generally tied closely to the economic growth of the respective franchise regions. 

Midstream 

Description of Assets

AltaGas'  Midstream  segment  is  comprised  of:  1)  the  Company's  global  export  assets,  which  connect  North  American 

production  into  key  downstream  markets  in  Asia;  2)  strategically-located  processing,  fractionation,  extraction  and  liquids 

handling infrastructure assets that convert raw production into usable products and link output from wellheads to downstream 

markets; 3) a natural gas transportation and storage platform, which includes AltaGas' 10 percent stake in the Mountain Valley 

Pipeline; and 4) various above and underground natural gas and liquids storage assets that are leveraged across the North 

American  energy  value  chain.  The  Midstream  segment  also  includes  AltaGas'  increased  ownership  stake  in  the  Petrogas 

assets and operations.

In Canada, AltaGas serves customers primarily in the Western Canada Sedimentary Basin (WCSB), with a strong weighting in 

the Montney play in NEBC. This includes gas gathering, processing, fractionating and delivery of natural gas and NGLs into 

downstream  pipeline  systems.  It  also  includes  connecting  producers  LPG  output  to  key  consuming  regions  in Asia.  In  total, 

AltaGas transacts on more than 1.4 Bcf/d of natural gas and NGLs, including gas gathering and processing, NGL extraction 

and fractionation, logistics, liquids handling, and global exports. Gas gathering systems move natural gas from producing wells 

to  processing  facilities,  where  certain  hydrocarbon  components  are  separated,  and  impurities  are  removed. The  gas  is  then 

compressed  to  meet  downstream  pipelines'  operating  specifications  for  transportation.  Extraction  and  fractionation  facilities 

reprocess natural gas to extract and recover ethane and additional NGLs. AltaGas has a total net licensed processing capacity 

of approximately 2.4 Bcf/d.

Through  the  RIPET  and  Ferndale  LPG  export  terminals, AltaGas  connects  North American  producers  and  aggregators  with 

global markets and provides incremental opportunities for improved pricing for propane and butane. On December 15, 2020, 

AltaGas  completed  the  acquisition  of  Petrogas,  increasing  its  indirectly  held  ownership  in  Petrogas  to  approximately  74 

percent with Idemitsu owning the remaining 26 percent (please refer to the Acquisition of Petrogas section of this MD&A for 

additional information). Subsequent to the transaction, AltaGas controls Petrogas and as such, AltaGas has the capability to 

export LPGs to Asia through the Ferndale facility. See the Global Exports section below for further details. 

AltaGas' logistics services include NGL pipelines, treating, storage, truck, and rail terminal infrastructure as well as natural gas 

and NGL marketing initiatives. AltaGas identifies opportunities to buy and resell NGLs for producers, and exchange, reallocate, 

or  resell  pipeline  and  storage  capacity  to  earn  a  profit.  With  the  emergence  of  the  global  exports  business,  the  logistics 

platform  provides  integral  support  for  managing AltaGas'  waterborne  and  rail  capacity  as  well  as  marketing  the  supply  and 

offtake of LPG volumes at RIPET and Ferndale. In support of the liquids handling operations, AltaGas manages a rail car fleet 

of approximately 4,600 rail cars. With the acquisition of Petrogas, the Midstream logistics infrastructure also includes Petrogas' 

core businesses including LPG exports and distribution, domestic terminals, wellsite fluids and fuels, and trucking and liquids 

handling. See the Fractionation and Logistics section below for more details.

The  Midstream  segment  includes  expansion  projects  under  development  or  construction,  as  discussed  under  the  Growth 

Capital section of this MD&A. 

Global Exports

AltaGas’ global export assets include the Company's RIPET and Ferndale export terminals, which are located in Northern B.C. 

and  Washington  State,  respectively.  These  terminals  facilitate  North American  producers  and  aggregators  to  access  global 

markets and provides incremental opportunities for improved price realization for propane and butane production. Between the 

two facilities, AltaGas has the ability to ship in excess of 130,000 Bbl/d.

RIPET  commenced  commercial  operations  on  May  23,  2019,  with  the  first  propane  shipment  departing  from  the  terminal  to 

Asia. RIPET has storage of 600,000 Bbls and throughput capacity of up to 80,000 Bbls/d at the terminal. As AltaGas builds on 

the Company's operational capabilities and continues to align with leading North American producers and global customers in 

Asia  through  long-term  tolling  agreements,  it  expects  to  continue  to  increase  throughput  from  RIPET.  On August  21,  2020, 

AltaGas  was  granted  an  additional  25-year  license  to  export  an  additional  46,000  bbl/d  of  propane  to  North American  and 

global  markets,  bringing  its  aggregate  propane  export  capacity  under  25-year  export  licenses  to  92,000  Bbls/d.  For  2021, 

AltaGas  has  in  place  multi-year  agreements  for  the  purchase  of  approximately  33  percent  of  the  propane  expected  to  be 

shipped from RIPET. The RIPET dock offers deep draft, sufficient to accommodate loading VLGCs.

With the acquisition of Petrogas, AltaGas also operates the Ferndale LPG terminal, which is capable of loading VLGCs, has 

800,000 Bbls of on-site storage, and currently can flow approximately 50,000 Bbls/d. Located approximately 100 miles north of 

Seattle, the terminal is also pipeline connected to two regional refineries, providing additional supply, sales, and fee-for-service 

opportunities for the facility.

AltaGas Ltd. – 2020 MD&A and Financial Statements - 17

 
The  RIPET  and  Ferndale  export  terminals  represent  strategic  outlet  points  for  North  American  LPG  volumes  as  they  are 

competitively situated to serve the high-demand Far East market with shorter average shipping times and competitive arbs as 

compared to the U.S. Gulf Coast or Arabian Gulf.

Terminal  demand  is  supported  through  various  long-term  purchase  agreements  with  Canadian  and  U.S.  suppliers,  primarily 

from key Northern British Columbia and Alberta gathering facilities and select U.S. producing regions, including the Bakken in 

North Dakota. Petrogas also maintains service agreements with numerous Tier 1 rail providers in order to leverage existing rail 

networks and secure competitively priced LPGs across North America. 

Gas Processing

Gas processing activities are comprised of gathering systems that move raw natural gas and NGLs from producing wells to 

processing  facilities,  where  impurities  and  certain  hydrocarbon  components  are  removed,  and  the  product  moves  down  the 

energy value chain. The gas is then compressed to meet downstream pipelines' operating specifications for transportation to 

North American  natural  gas  markets. All  of AltaGas'  processing  facilities  are  capable  of  extracting  NGLs  and  converting  the 

throughput  into  usable  products.  The  facilities  provide  revenues  based  on  take-or-pay  contracts  and  fee-for-service 

arrangements  with  its  customers,  with  the  latter  based  on  volumes  processed.  A  significant  portion  of  AltaGas'  Midstream 

contracts flow the Company's operating costs through to the producers. AltaGas' processing infrastructure includes:

▪

▪

▪

▪

▪

The Townsend facility, a 550 Mmcf/d gas processing facility, along with the related egress pipelines, truck terminal, 

and  NGL  treatment  infrastructure  (the  Townsend  complex),  which  is  wholly  owned  and  operated  by  AltaGas.  The 

majority  of  the  processing  capacity  is  contracted  with  Montney  producers  in  the  area  under  long-term  take-or-pay 

agreements.  In  2018,  AltaGas  entered  into  definitive  agreements  with  Kelt  Exploration  Ltd.  to  provide  an  energy 

infrastructure solution for the liquids-rich Inga Montney development located in NEBC. In the second quarter of 2020, 

Townsend  2B  and  a  gas  gathering  pipeline  that  connects  upstream  fields  to AltaGas  facilities  were  commissioned, 

which  added  198  Mmcf/d  C3+  deep  cut  gas  processing  capacity  at  the Townsend  Complex.  In  the  third  quarter  of 

2020,  ConocoPhillips  acquired  oil  and  gas  assets  in  the  Inga/Fireweed/Stoddard  division  in  the  Montney  area  from 

Kelt. All operating agreements of AltaGas remain in effect;

The Gordondale facility, which has licensed capacity of 150 Mmcf/d of natural gas and is wholly owned and operated 

by  AltaGas.  The  Gordondale  facility  processes  gas  gathered  from  Birchcliff  Energy  Ltd.’s  Gordondale  Montney 

development under a long-term take-or-pay contract. The plant is equipped with liquids extraction facilities to capture 

the NGL value for the producer;

The Blair Creek facility, which has licensed capacity of 120 Mmcf/d of natural gas and is wholly owned and operated 

by  AltaGas.  The  facility  processes  gas  gathered  from  producers  in  the  area.  The  plant  is  equipped  with  liquids 

extraction facilities to capture the NGL value for the producer;

The Aitken Creek processing facilities, in which AltaGas has a 50 percent ownership interest. Black Swan Energy Ltd. 

(Black  Swan)  owns  the  remaining  50  percent  interest.  These  facilities  include  Aitken  Creek  North,  an  operating 

shallow gas plant with a current capacity of 110 Mmcf/d (55 Mmcf/d net), and Nig Creek, currently a shallow gas plant 

with capacity of 100 Mmcf/d (50 Mmcf/d net) that came on-stream in the third quarter of 2019. Phase 1 of Nig Creek 

GP2B  will  increase  inlet  capacity  by  55  Mmcf/d  (28  Mmcf/d  net).  Phase  1  of  Nig  Creek  GP2B  is  expected  to  be 

commissioned  in  the  third  quarter  of  2021.  The Aitken  processing  facilities  are  located  in  the  liquids  rich  Montney 

resource play in NEBC and are operated by Black Swan. AltaGas and Black Swan have also entered into long-term 

processing, transportation, and marketing agreements that will include new AltaGas liquids handling infrastructure in 

NEBC; 

The Harmattan facility, which has a natural gas processing capacity of 490 Mmcf/d and is wholly owned and operated 

by AltaGas.  Harmattan's  natural  gas  processing  consists  of  sour  gas  treating,  co-stream  straddle  processing,  and 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 18

NGL  extraction.  In  addition,  Harmattan  has  fractionation  and  terminalling  facilities  (see  Fractionation  and  Logistics 

section below); and

▪

Interests  in  four  NGL  extraction  plants  with  net  licensed  inlet  capacity  of  1.0  Bcf/d. The  extraction  plants  consist  of 

Edmonton  Ethane  Extraction  Plant  (EEEP),  Joffre  Ethane  Extraction  Plant  (JEEP),  Pembina  Empress  Extraction 

Plant (PEEP), and the Younger extraction plant (Younger). The extraction assets provide stable fixed-fee or cost-of-

service type revenues and margin based revenues. The natural gas supply to EEEP, JEEP, and PEEP depends on 

natural  gas  demand  pull  from  residential,  commercial  and  industrial  usage  inside  and  outside  of  Western  Canada, 

and  gas  liquids  demand  pull  from  the  Alberta  petrochemical  market  and  propane  heating.  Natural  gas  supply  to 

Younger is dependent on the amount of raw natural gas processed at the McMahon gas plant, which is based on the 

robust natural gas producing region of NEBC.

Fractionation and Logistics

Fractionation  production  is  a  function  of  NGL  mix  volumes  processed,  liquids  composition,  recovery  efficiency  of  the  plants, 

and plant on-line time. Due to the integration and inter-connectivity of AltaGas' Midstream assets, the fractionation and logistics 

activities provide integral services to the other Midstream businesses and customers by providing access to high value NGL 

products with access to North American and global markets through rail networks, pipelines, RIPET, and Ferndale. 

AltaGas'  logistics  infrastructure  consists  of  NGL  pipelines,  treating,  storage,  truck,  and  rail  terminal  infrastructure  centered 

around AltaGas’  key  Midstream  operating  assets  at  RIPET,  Harmattan  and,  in  NEBC,  Townsend  and  North  Pine.  With  the 

close of the Petrogas acquisition, AltaGas' fractionation and logistics business also includes Petrogas' terminals, wellsite fluids 

and fuels, and trucking and liquids handling.

AltaGas’ fractionation and logistics infrastructure includes:

▪

▪

▪

▪

▪

▪

The North Pine facility, which is the only custom fractionation plant in British Columbia, providing area producers with 

a lower cost, higher netback alternative for their NGLs than transporting and fractionating in Edmonton, Alberta. The 

first train of the North Pine facility is capable of processing up to 10,000 Bbls/d of NGL mix. The second train, 

commissioned in the first quarter of 2020, provides an additional 10,000 Bbls/d of NGL mix following execution of 

agreements with Black Swan and Kelt in the second half of 2018. The North Pine facility is connected to the 

Townsend truck terminal via the North Pine pipelines, to the Tourmaline Gundy facility, and also has access to the 

Canadian National (CN) rail network, allowing the transportation of propane, butane, and condensate to North 

American markets and propane to global markets via RIPET and butane via Ferndale; 

The  Harmattan  gas  processing  complex,  which  has  NGL  fractionation  capacity  of  35,000  Bbls/d,  a  450  Bbls/d

Petrogas'  terminals  and  storage  business,  which  provides  support  to  the  LPG  exports  and  distribution  business  by 

providing  the  ability  to  source,  transport,  process,  store,  and  deliver  products  through  strategically  located  fixed 

assets throughout North America. In addition, the terminals business provides various storage and handling services 

to third-party customers through take-or-pay and fee-for-service agreements, which provide earnings stability through 

volatile commodity price environments. The terminals business consists of strategically located crude and NGL assets 

which provide storage, blending, rail, and truck logistical support and waterborne LPG export capabilities. Petrogas' 

terminal business includes Griffith LPG Terminal, which is capable of handling approximately 12,000 Bbls/d of NGLs, 

700,000 barrels of underground cavern storage and up to 220 railcars rail siding capacity; the Strathcona Storage JV, 

which has four underground storage salt caverns in service and a fifth cavern under development with each cavern 

providing  approximately  629,000  Bbls  of  storage  capacity;  and  Sarnia  Storage  and  Crude  Oil  Terminal  JV,  which 

provides  up  to  2.1  million  barrels  of  crude  oil  and  refined  product  storage  capacity  with  outbound  throughput 

supported  by  10,000  Bbls/d  of  rail  loading  capacity. The  right  to  access  the  terminal  assets  under  the  joint  venture 

arrangement have been recorded as a lease by Petrogas;

50  percent  ownership  of  the  5.3  Bcf  Sarnia  natural  gas  storage  facility,  which  is  connected  to  the  Dawn  Hub  in 

Eastern Canada;

Three primary trucking entities which Petrogas operates, providing transportation related services within the WCSB 

and the Pacific Northwest in the U.S. by hauling frac fluid, produced water, crude oil, and NGLs between producers, 

terminals, customers and end users; and

Enerchem International Inc., a wholly owned subsidiary of Petrogas, is a Canadian corporation which focuses on the 

production  of  drilling  and  wellsite  fluids  and  consumer  fuels.  Through  the  fractionation  of  crude  oil  feedstock, 

Enerchem  produces  and  distributes  proprietary  hydrocarbon  fluids  for  fracturing  and  drilling  of  oil  and  gas  wells  to 

improve productivity and to resolve oilfield production challenges for downstream producers. Enerchem operates two 

primary facilities located in Sundre and Slave Lake, Alberta, which are capable of processing over 1.5 million barrels 

of  finished  products  per  year.  These  plants  are  supported  by  various  ancillary  storage  and  distribution  facilities 

located across the WCSB, providing over 150,000 barrels of storage capacity, strategically placed within the vicinity of 

active drilling regions. 

Energy Services

In addition to supporting the other Midstream activities within AltaGas, the logistics business identifies opportunities to buy and 

resell NGLs for producers, and exchange, reallocate or resell pipeline and storage capacity to earn a profit. Net revenues from 

these activities are derived from low risk opportunities based on transportation cost differentials between pipeline systems and 

differences  in  commodity  prices  from  one  period  to  another.  Margins  are  earned  by  locking  in  buy  and  sell  transactions  in 

compliance  with AltaGas’  credit  and  commodity  risk  policies. AltaGas  also  provides  energy  procurement  services  for  utilities 

gas users and manages the third-party pipeline transportation requirements for many of its gas marketing customers. 

Petrogas' marketing business is focused on the purchase, sale, exchange, and distribution of NGLs and crude oil, primarily in 

proximity  to  its  strategically  owned  and  leased  asset  base.  By  leveraging  Petrogas'  fully  integrated  infrastructure  base  and 

extensive logistical capabilities, the marketing team is able to source competitively priced supply at the key hubs and across 

various hydrocarbon basins in order to capture arbitrage opportunities derived through regional pricing differentials. Marketing 

efforts  are  driven  by  two  primary  focuses:  1)  domestic  NGL  and  crude  oil  wholesale,  and  2)  LPG  waterborne  exports. 

Additionally, this business provides operational support to the Ferndale export terminal by providing product supply and export 

sales  agreement  negotiation  services.  Petrogas  supports  its  distribution  efforts  by  maintaining  an  extensive  leased  rail  fleet. 

Leases are established on a staggered maturity schedule with multiple lessors, to ensure railcar integrity and up-to-date DOT 

classification and all leases are on a full-service basis.

gas  and  is  expected  to  be  placed  into  service  in  the  second  half  of  2021.  In  April  2018,  AltaGas  entered  into  a  separate 

agreement to acquire a 5 percent equity interest in a lateral project to build an interstate natural gas pipeline (MVP Southgate) 

which will receive natural gas from MVP. The MVP Southgate pipeline is expected to be placed into service in the second half 

of 2022 due to ongoing legal and regulatory challenges. 

AltaGas  also  held  a  10  percent  interest  in  the  Constitution  pipeline  through  a  10  percent  equity  investment  in  Constitution 

Pipeline Company, LLC. The natural gas pipeline venture was proposed to transport natural gas from the Marcellus region in 

northern  Pennsylvania  to  major  northeastern  markets.  In  February  2020,  following  evaluations  of  the  diminished  underlying 

economics for the proposed Constitution pipeline project, the partners of Constitution Pipeline Company, LLC elected not to 

proceed with the project.

Capitalize on Opportunities 

To take advantage of opportunities, including the continued Montney LPG growth and the increasing Asian demand for LPG, 

AltaGas plans to grow its Midstream business by expanding and optimizing strategically-located assets as well as its global

Corporate/Other

Description of Assets

In  addition  to  Corporate  activities  and  assets,  AltaGas'  Corporate/Other  segment  includes  582  MW  of  operational  gross 

capacity from remaining natural gas-fired and distributed generation power assets located in the U.S., primarily California and 

Colorado. 

Specifically, the core remaining power assets in the Corporate/Other segment include: 

▪

▪

Two  natural  gas-fired  plants  with  577  MW  of  generating  capacity  in  the  United  States:  the 507  MW  Blythe  Energy 

Center (Blythe) in California and the 70 MW Brush II Facility (Brush) in Colorado. Blythe and Brush are both under 

Power Purchase Arrangements (PPA) with a creditworthy utilities; and

Certain remaining distributed generation assets.

In  Southern  California,  the  507  MW  Blythe  Energy  Center  utilizes  gas-fired  generation  to  produce  power  and  serves  the 

transmission grid operated by the California Independent System Operator (CAISO) to cover periods of high demand primarily 

driven by the Los Angeles area. Due to the structure of the long-term PPA with Southern California Edison (SCE), the majority 

of the revenue from the facility is derived from being available to produce and not from actual production, which reduces risk 

and provides stable cash flow. The facility is directly connected to an El Paso Gas Company natural gas pipeline for its primary 

supply and a Southern California Gas Company pipeline as a secondary supply source, and interconnects to SCE and CAISO 
via a 67‑mile transmission line also owned by Blythe and is part of the Blythe Energy Center. In 2019, AltaGas announced the 
successful recontracting of the Blythe facility to SCE. With the approval of the new PPA with SCE received by the California 

Public  Utilities  Commission  in  January  2020,  Blythe  is  contracted  under  a  PPA  until  December  31,  2023.  Under  the  tolling 

agreement, SCE has exclusive rights to all capacity, energy, ancillary services, and resource adequacy benefits during the PPA 

term.  In  addition, AltaGas  is  in  the  initial  stages  of  permitting  a  new  40  MW  stand-alone  energy  storage  project  in  Goleta, 

California.

Beginning in 2020, Management no longer adjusts normalized EBITDA or normalized net income for changes in the fair value of natural gas optimization 

inventory.  Please  see  the Non-GAAP  Financial  Measures  section  of  this  MD&A  for  additional  detail. As  such,  comparative  periods  have  been  adjusted  to 

reflect the before and after-tax impacts of this change to normalized EBITDA and normalized net income, respectively. 

(3) Dividends declared per common share per month: $0.08 beginning December 2018, increased to $0.0833 per share beginning December 2020.

(4) Weighted average.

Three Months Ended December 31

Normalized EBITDA for the fourth quarter of 2020 was $392 million, compared to $436 million for the same quarter in 2019. 

Factors  negatively  impacting  AltaGas'  normalized  EBITDA  in  the  fourth  quarter  of  2020  included  lower  realized  storage 

spreads  at  WGL  Midstream,  lower  realized  merchant  margins  at  RIPET,  lower  equity  earnings  from  Petrogas  for  the  period 

prior  to  the  acquisition  of  Petrogas  on  December  15,  2020,  lower  NGL  marketing  margins,  warmer  weather  at  certain  of 

AltaGas'  Utilities,  higher  expenses  related  to  employee  benefits  and  incentive  plans,  and  lower  frac  exposed  NGL  volumes. 

Other factors negatively impacting normalized EBITDA included the impact of asset sales, including WGL Midstream's indirect 

non-operating  interest  in  the  Central  Penn  Pipeline  (Central  Penn)  in  November  2019,  and  ACI  in  March  2020.  Factors 

positively  impacting  normalized  EBITDA  included  higher  contributions  from  NEBC  assets  primarily  due  to  growth  capital 

projects placed in service in 2020, higher rates and gas margins at SEMCO, higher gas margins from WGL's Retail Energy

Marketing  business  due  to  favorable  pricing,  higher  revenue  from  ARP  program  spend,  and  contributions  from  the 

consolidation of Petrogas after closing the acquisition on December 15, 2020. Petrogas equity income for the period prior to 

acquisition was lower primarily due to lower commodity prices in 2020 as well as the absence of a one-time payment related to 

the termination of a customer contract in the fourth quarter of 2019. On December 15, 2020, AltaGas acquired an additional 37 

percent  of  Petrogas,  resulting  in  AltaGas'  ownership  of  Petrogas  being  increased  to  approximately  74  percent.  As  such, 

Petrogas'  results  have  been  consolidated  for  the  period  subsequent  to  close  (please  refer  to  the  Acquisition  of  Petrogas 

section of this MD&A for additional information). For the three months ended December 31, 2020, the average Canadian/U.S. 

dollar  exchange  rate  decreased  to  1.30  from  an  average  of  1.32  in  the  same  quarter  of  2019,  resulting  in  a  decrease  in 

normalized EBITDA of approximately $5 million. 

Net income applicable to common shares for the fourth quarter of 2020 was $48 million ($0.17 per share), compared to a net 

loss  of  $103  million  ($0.37  per  share)  for  the  same  quarter  in  2019.  The  increase  was  mainly  due  to  lower  provisions  on 

assets,  the  gain  recorded  on  the  re-measurement  of  AltaGas'  previously  held  equity  investment  in  AltaGas  Idemitsu  Joint 

Venture LP (AIJVLP) upon acquisition of Petrogas, lower unrealized losses on risk management contracts, and lower interest 

expense, partially offset by the same previously referenced factors impacting normalized EBITDA, the absence of the gain on 

the sale of the U.S. distributed generation assets in the third quarter of 2019, the dilution loss and other adjustments to equity 

income related to the acquisition of Petrogas, and higher income tax expense. 

Normalized funds from operations for the fourth quarter of 2020 were $327 million ($1.17 per share), compared to $332 million 

($1.19  per  share)  for  the  same  quarter  in  2019.  The  decrease  was  mainly  due  to  the  same  factors  impacting  normalized 

EBITDA, partially offset by lower interest expense. In the fourth quarter of 2020, prior to the acquisition of Petrogas, AltaGas 

received $3 million of dividend income from the Petrogas Preferred Shares (2019 - $3 million). 

In  the  fourth  quarter  of  2020,  upon  the  acquisition  of  Petrogas,  AltaGas  recorded  a  gain  on  the  re-measurement  of  the 

Company's previously held equity investment in AIJVLP of approximately $22 million. In addition, in the fourth quarter of 2020, 

AltaGas  recorded  pre-tax  provisions  on  assets  of  approximately  $104  million  ($79  million  after-tax)  primarily  related  to  the 

Alton Natural Gas Storage Project, which was impaired as AltaGas does not believe that the future expected cash generation 

from  the  project  aligns  with  the  current  carrying  value.  In  the  fourth  quarter  of  2019,  AltaGas  recorded  pre-tax  gains  on 

dispositions  of  assets  of  approximately  $56  million.  This  was  comprised  of  a  pre-tax  gain  of  $68  million  on  certain  U.S. 

distributed  generation  projects  which  were  sold  in  the  third  quarter  of  2019  but  transferred  to  the  purchaser  in  the  fourth 

quarter of 2019, and a pre-tax loss of approximately $12 million on the disposition of equity investments, primarily related to 

WGL Midstream's indirect non-operating interest in Central Penn. In addition, in the fourth quarter of 2019, AltaGas recorded 

pre-tax  provisions  on  assets  of  approximately  $415  million  ($319  million  after-tax),  primarily  related  to  various  assets  in  the 

Corporate/Other segment and a sour gas treatment facility in Alberta. 

Operating and administrative expenses for the fourth quarter of 2020 were $342 million, compared to $340 million for the same 

quarter  in  2019. The  slight  increase  was  mainly  due  to  increased  costs  related  to  operations  at  the  NEBC  pipeline  projects 

which  were  placed  in  service  in  the  second  and  third  quarters  of  2020  and  increased  professional  and  consulting  fees. 

Depreciation and amortization expense for the fourth quarter of 2020 was $108 million, compared to $109 million for the same 

quarter  in  2019.  The  slight  decrease  was  mainly  due  to  the  impact  of  provisions  recorded  against  property,  plant,  and 

equipment in the fourth quarter of 2019, partially offset by new assets placed in-service in 2020. Interest expense for the fourth 

quarter of 2020 was $68 million, compared to $77 million for the same quarter in 2019. The decrease was predominantly due 

to lower average interest rates compared to 2019. 

AltaGas recorded an income tax expense of $5 million for the fourth quarter of 2020 compared to an income tax recovery of 

$87 million in the same quarter in 2019. The increase in income tax expense was mainly due to higher tax recoveries on asset 

provisions in the fourth quarter of 2019. Current tax expense of $14 million was recorded in the fourth quarter of 2020, of which 

approximately $2 million related to a tax recovery on asset sales. 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 24

 
Normalized net income was $147 million ($0.53 per share) for the fourth quarter of 2020, compared to $194 million ($0.70 per 

share) reported for the same quarter in 2019. The decrease was mainly due to the same factors impacting normalized EBITDA 

and higher income tax expense, partially offset by lower interest expense and lower depreciation and amortization expense. 
Normalizing items in the fourth quarter of 2020 increased normalized net income by $99 million and included after‑tax amounts 
related to transaction costs related to acquisitions and dispositions, restructuring costs, provisions on assets, unrealized losses 

on risk management contracts, dilution loss and other adjustments to equity income related to the acquisition of Petrogas, and 

the  gain  recorded  on  the  re-measurement  of  AltaGas'  previously  held  equity  investment  in  AIJVLP  upon  acquisition  of 

Petrogas.  Normalizing  items  in  the  fourth  quarter  of  2019  increased  normalized  net  income  by  $297  million  and  included 
after‑tax amounts related to gains on sale of assets, merger commitment cost recovery due to a change in timing related to 
certain  WGL  merger  commitments,  transaction  costs  related  to  acquisitions  and  dispositions,  unrealized  losses  on  risk 

management  contracts,  provisions  on  assets,  provisions  on  investments  accounted  for  by  the  equity  method,  gain  on 

redemption  of  Washington  Gas  preferred  shares,  unitary  tax  adjustment  related  to  the  acquisition  of  WGL  and  U.S.  asset 

sales, and the impact of a statutory tax rate change in Alberta. Please refer to the Non-GAAP Financial Measures section of 

this MD&A for further details on normalization adjustments. 

Year Ended December 31

Normalized EBITDA for the year ended December 31, 2020 was $1,310 million, compared to $1,302 million in 2019. Factors 

positively  impacting  normalized  EBITDA  included  the  impact  of  Washington  Gas'  2019  Maryland  and  Virginia  rate  cases, 

higher  contributions  from  NEBC  assets  primarily  due  to  growth  capital  projects  placed  in  service  in  2020,  the  impact  of  a 

change in accounting principle relating to Washington Gas' net periodic pension and other post-retirement benefit plan costs 

(please  refer  to  the  Critical  Accounting  Estimates  section  of  this  MD&A  for  additional  information),  higher  rates  effective 

January 2020 at SEMCO due to the 2019 rate case application, higher revenue from ARP spend, higher Allowance for Funds 

Used  During  Construction  (AFUDC)  related  to  MVP,  additional  contracted  ethane  volumes  at  the  extraction  facilities, 

contributions  from  Petrogas  for  the  period  after  acquisition,  contributions  from  RIPET,  which  was  placed  into  service  in  May 

2019,  and  a  shorter  planned  spring  outage  at  Blythe  compared  to  2019.  These  were  partially  offset  by  the  impact  of  asset 

sales, including the U.S. distributed generation assets in September 2019, WGL Midstream's indirect non-operating interest in 

Central Penn in November 2019, WGL Midstream's interest in the Stonewall Gas Gathering System (Stonewall) in May 2019, 

ACI  in  March  2020,  Pomona  in  July  2020,  as  well  as  lower  equity  earnings  from  Petrogas  prior  to  the  acquisition  of  the 

additional interest in Petrogas on December 15, 2020, lower U.S. Midstream financial hedge gains and storage withdrawals, 

lower frac exposed volumes and lower realized frac spreads, lower usage at certain of the utilities, and the cancellation of late 

fees and related charges by AltaGas' Utilities due to COVID-19. Petrogas equity income for the period prior to acquisition was 

lower  primarily  due  to  lower  commodity  prices  during  2020.  Export  deliveries  up  until  the  month  of  April  were  lower  than 

planned due to industry conditions and subsequently have resumed to planned levels. In addition, in the fourth quarter of 2019, 

Petrogas  earnings  included  a  large  one-time  payment  related  to  the  termination  of  a  customer  contract.  On  December  15, 

2020, AltaGas acquired an additional 37 percent of Petrogas, resulting in AltaGas' ownership of Petrogas being increased to 

approximately 74 percent. As such, Petrogas' results have been consolidated for the period subsequent to close (please refer 

to  the  Acquisition  of  Petrogas  section  of  this  MD&A  for  additional  information).  For  the year  ended  December  31,  2020,  the 

average  Canadian/U.S.  dollar  exchange  rate increased  to  1.34  from  an  average  of 1.33  in  2019,  resulting  in  an  increase  in 

normalized EBITDA of approximately $4 million. 

Net  income  applicable  to  common  shares  for  the  year  ended  December  31,  2020  was  $486  million  ($1.74  per  share), 

compared  to  $769  million  ($2.78  per  share)  in  2019. The  decrease  was  mainly  due  to  the  absence  of  gains  on  asset  sales 

recorded  in  2019  (including  Northwest  Hydro,  Stonewall,  and  distributed  generation  assets),  dilution  loss  and  other 

adjustments to equity income related to the acquisition of Petrogas, and higher income tax expense, partially offset by lower 

provisions on assets, the gain on the disposition of AltaGas Canada Inc. (ACI, now named TriSummit Utilities Inc.), the gain 

recorded  on  the  re-measurement  of AltaGas'  previously  held  equity  investment  in AIJVLP  upon  the  acquisition  of  Petrogas, 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 25

 
gains  on  the  sales  of  Pomona  and  Ripon,  higher  unrealized  gains  on  risk  management  contracts,  the  same  previously 

referenced factors impacting normalized EBITDA, lower interest expense, and lower depreciation and amortization expense. 

Normalized funds from operations for the year ended December 31, 2020 were $1,003 million ($3.59 per share), compared to 

$895 million ($3.23 per share) in 2019. The increase was mainly due to the same drivers as normalized EBITDA and lower 

interest  expense.  In  2020,  prior  to  the  acquisition  of  Petrogas,  AltaGas  received  $13  million  of  dividend  income  from  the 

Petrogas Preferred Shares (2019 - $13 million) and $5 million of common share dividends from Petrogas (2019 - $6 million). 

In 2020, AltaGas recorded pre-tax gains on dispositions of assets of approximately $223 million. This was comprised of a pre-

tax gain of $206 million on the disposition of AltaGas' equity investment in ACI, a pre-tax gain of $9 million related to certain 

distributed generation projects which were transferred to the purchaser in 2020, a pre-tax gain of $5 million on the disposition 

of Pomona, and a pre-tax gain of $3 million on the disposition of Ripon. In 2020, upon the acquisition of Petrogas, AltaGas also 

recorded  the  previously  mentioned  gain  on  the  re-measurement  of  it's  previously  held  equity  investment  in  AIJVLP  of 

approximately $22 million. In 2020, AltaGas recorded pre-tax provisions on assets of approximately $109 million ($81 million 

after-tax) primarily related to the Alton Natural Gas Storage Project, certain U.S. distributed generation projects which had not 

yet  transferred  to  the  purchaser,  and  land  parcels  located  near  the  Harmattan  gas  processing  plant.  In  addition,  in  2020, 

AltaGas  recorded  a  pre-tax  provision  on  equity  investments  of  approximately  $7  million  ($6  million  after-tax)  for  costs 

associated  with  the  Constitution  pipeline  project  (Constitution)  which  was  canceled  in  February  2020.  In  2019,  AltaGas 

recorded pre-tax gains on dispositions of assets of approximately $875 million. This was mainly comprised of a pre-tax gain of 

$688  million  on  the  sale  of  the  remaining  interest  in  the  Northwest  Hydro  facilities,  a  pre-tax  gain  of  $100  million  on  the 

disposition  of  the  U.S.  distributed  generation  assets,  a  pre-tax  gain  of  $34  million  on  the  disposition  of  WGL  Midstream's 

interest in Stonewall, a pre-tax loss of $6 million on the sale of Canadian non-core power assets, a pre-tax loss of $1 million on 

the sale of a WGL Energy Systems financing receivable, a pre-tax gain of $5 million on the sale of certain non-core Midstream 

processing facilities, and the previously mentioned losses recorded in the fourth quarter of 2019. In 2019, AltaGas recorded 

pre-tax provisions on assets of approximately $416 million ($320 million after-tax) primarily related to the previously mentioned 

provisions recorded in the fourth quarter of 2019 and $1 million related to a capital spare turbine in storage which was sold in 

the third quarter of 2019. In addition, in 2019, AltaGas recorded pre-tax provisions on equity investments of approximately $46 

million ($29 million after-tax), including $44 million related to WGL Midstream's indirect, non-operating interest in Central Penn 

which was sold in November 2019, and $2 million related to biomass investments which were sold in the third quarter of 2019. 

Operating  and  administrative  expenses  for  the  year  ended  December  31,  2020  were  $1,267  million,  compared  to  $1,299 

million in 2019. The decrease was mainly due to the impact of asset sales in the second half of 2019, recoveries related to 

CEWS, and lower employee salary expenses, partially offset by the impact of RIPET coming online in May 2019 and increased 

costs  related  to  operations  at  the  NEBC  pipeline  projects,  which  were  placed  in  service  in  the  second  and  third  quarters  of 

2020.  Depreciation  and  amortization  expense  for  the  year  ended  December  31,  2020  was  $414  million,  compared  to  $438 

million  in  2019.  The  decrease  was  mainly  due  to  an  amortization  adjustment  related  to  the  derecognition  of  an  intangible 

liability, the impact of the sale of U.S. distributed generation assets in September 2019 and the impact of provisions recorded 

against property, plant, and equipment in the fourth quarter of 2019, partially offset by RIPET coming online in May 2019 and 

new assets placed in-service. Interest expense for the year ended December 31, 2020 was $274 million, compared to $346 

million in 2019. The decrease was predominantly due to lower average interest rates compared to 2019. 

AltaGas recorded an income tax expense of $127 million for the year ended December 31, 2020 compared to an income tax 

recovery of $28 million in 2019. The increase in tax expense was mainly due the absence of tax recoveries on the disposition 

of the U.S. distributed generation assets in the third quarter of 2019, unitary tax rate adjustments, and a one-time tax recovery 

related to the Alberta Job Creation Tax Cut in the second quarter of 2019, partially offset by lower tax expense on dispositions 

in Canada in 2020. Current tax expense of approximately $1 million was recorded in 2020, of which approximately $2 million 

related to a tax recovery on asset sales. 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 26

 
Normalized net income was $396 million ($1.42 per share) for the year ended December 31, 2020, compared to $347 million 

($1.25  per  share)  in  2019.  The  increase  was  mainly  due  to  the  same  previously  referenced  factors  impacting  normalized 

EBITDA,  lower  interest  expense,  and  lower  depreciation  and  amortization  expense,  partially  offset  by  higher  income  tax 

expense. Normalizing items in the year ended December 31, 2020 reduced normalized net income by $90 million and included 
after‑tax  amounts  related  to  gains  on  sale  of  assets,  transaction  costs  related  to  acquisitions  and  dispositions,  restructuring 
costs, provisions on assets, provisions on investments accounted for by the equity method, dilution loss and other adjustments 

to  equity  income  related  to  the  acquisition  of  Petrogas,  COVID-19  related  costs,  gain  recorded  on  the  re-measurement  of 

AltaGas' previously held equity investment in AIJVLP upon acquisition of Petrogas, and unrealized gains on risk management 

contracts.  Normalizing  items  in  the  year  ended  December  31,  2019  reduced  normalized  net  income  by  $422  million  and 
included  after‑tax  amounts  related  to  gains  on  sale  of  assets,  merger  commitment  cost  recovery  due  to  a  change  in  timing 
related to certain WGL merger commitments, transaction costs related to acquisitions and dispositions, unrealized losses on 

risk  management  contracts,  losses  on  investments,  provisions  on  assets,  provisions  on  investments  accounted  for  by  the 

equity  method,  a  gain  on  the  redemption  of  Washington  Gas  preferred  shares,  the  impact  of  a  statutory  tax  rate  change  in 

Alberta, and a unitary tax adjustment related to the acquisition of WGL and U.S. asset sales. Please refer to the Non-GAAP 

Financial Measures section of this MD&A for further details on normalization adjustments.

In prior years, normalized EBITDA also included adjustments for changes in fair value of natural gas optimization inventory; however, beginning in 2020, this 

is  no  longer  adjusted  for  as  Management  believes  this  more  accurately  represents  AltaGas'  operating  profitability.  Instead,  normalized  EBITDA  is  now 

adjusted for unrealized gains or losses on hedges related to this optimization inventory which is included in unrealized losses (gains) on risk management 

contracts.  Comparative  periods  have  been  restated  to  reflect  this  change.  As  a  result  of  this  change,  2019  normalized  EBITDA  is  now  $1,302  million, 

compared to $1,271 million disclosed in the MD&A for the year ended December 31, 2019.

EBITDA is a measure of AltaGas' operating profitability prior to how business activities are financed, assets are amortized, or 

earnings  are  taxed.  EBITDA  is  calculated  from  the  Consolidated  Statements  of  Income  using  net  income  (loss)  after  taxes 
adjusted for pre‑tax depreciation and amortization, interest expense, and income taxes.

Normalized EBITDA includes additional adjustments for transaction costs (recoveries) related to acquisitions and dispositions, 

merger  commitment  costs  (recoveries)  due  to  a  change  in  timing  related  to  certain  WGL  merger  commitments,  unrealized 

losses  (gains)  on  risk  management  contracts,  non-controlling  interest  of  certain  investments  to  which  HLBV  accounting  is 

applied,  losses  on  investments,  gains  on  sale  of  assets,  restructuring  costs,  dilution  loss  and  other  adjustments  to  equity 

income  related  to  the  acquisition  of  Petrogas,  gain  on  re-measurement  of  previously  held  equity  investment  in  AIJVLP, 

COVID-19  related  costs,  provisions  on  assets,  provisions  on  investments  accounted  for  by  the  equity  method,  distributed 

generation  asset  related  investment  tax  credits,  foreign  exchange  losses  (gains),  and  accretion  expenses  related  to  asset 

retirement  obligations.  In  addition  to  the  dilution  loss,  the  other  adjustments  to  equity  income  primarily  included  amounts 

related to severance, transaction costs, and impairment losses related to the acquisition of Petrogas.  COVID-19 related costs 

normalized in 2020 were primarily comprised of credit losses that were incremental and directly attributable to the COVID-19 

pandemic  and  charges  incurred  to  support  remote  work  arrangements.  AltaGas  presents  normalized  EBITDA  as  a 

supplemental measure. Normalized EBITDA is used by Management to enhance the understanding of AltaGas' earnings over 

periods. The metric is frequently used by analysts and investors in the evaluation of entities within the industry as it excludes

$324 million disclosed in the MD&A for the year ended December 31, 2019.

Normalized  net  income  represents  net  income  (loss)  applicable  to  common  shares  adjusted  for  the  after-tax  impact  of 

transaction costs (recoveries) related to acquisitions and dispositions, merger commitment costs (recoveries) due to a change

Normalized  funds  from  operations,  normalized  adjusted  funds  from  operations,  and  normalized  utility  adjusted  funds  from 

operations are used to assist Management and investors in analyzing the liquidity of the Corporation. Management uses these 

measures to understand the ability to generate funds for capital investments, debt repayment, dividend payments, and other 

investing activities. 

Funds  from  operations  are  calculated  from  the  Consolidated  Statements  of  Cash  Flows  and  are  defined  as  cash  from 

operations,  adjusted  for  net  changes  in  operating  assets  and  liabilities  and  expenditures  incurred  to  settle  asset  retirement 
obligations. Normalized funds from operations is  based on funds from operations, further adjusted for non‑operating related 
expenses  (net  of  current  taxes)  such  as  transaction  costs  (recoveries)  related  to  acquisitions  and  dispositions,  merger 

commitment  costs  (recoveries),  current  tax  expense  (recovery)  on  asset  sales,  COVID-19  related  costs,  and  restructuring 

costs. Normalized adjusted funds from operations is based on normalized funds from operations, further adjusted to remove 

the  impact  of  cash  transactions  with  non-controlling  interests,  non-utility  maintenance  capital,  and  preferred  share  dividends 

paid.  Normalized  utility  adjusted  funds  from  operations  is  based  on  normalized  adjusted  funds  from  operations,  further 

adjusted for Utilities segment depreciation and amortization.

Funds  from  operations,  normalized  funds  from  operations,  normalized  adjusted  funds  from  operations,  and  normalized 

adjusted funds from operations as presented should not be viewed as an alternative to cash from operations or other cash flow 

measures calculated in accordance with GAAP.

Normalized  income  tax  expense  represents  income  tax  recovery  (expense)  adjusted  for  the  tax  impact  of  transaction  costs 

(recoveries) related to acquisitions and dispositions, unrealized losses (gains) on risk management contracts, gains on sale of 

assets,  restructuring  costs,  provisions  on  assets,  provisions  on  investments  accounted  for  by  the  equity  method,  unitary  tax 

adjustment related to the acquisition of WGL and U.S. asset sales, statutory tax rate change, and distributed generation asset 

related investment tax credits. This measure is used by Management to enhance the comparability of the impact of income tax 

on AltaGas’ earnings, as it reflects the underlying performance of AltaGas’ business activities, and is presented to provide this 

perspective to analysts and investors.

Net Debt and Net Debt to Total Capitalization

Net  debt  and  net  debt  to  total  capitalization  are  used  by  the  Corporation  to  monitor  its  capital  structure  and  financing 

requirements.  It  is  also  used  as  a  measure  of  the  Corporation’s  overall  financial  strength  and  is  presented  to  provide  this 

perspective to analysts and investors. Net debt is defined as short-term debt (excluding third-party project financing obtained 

for the construction of certain energy management services projects), plus current and long-term portions of long-term debt, 

less  cash  and  cash  equivalents.  Total  capitalization  is  defined  as  net  debt  plus  shareholders’  equity  and  non-controlling 

interests. Additional  information  regarding  these  non-GAAP  measures  can  be  found  under  the Capital  Resources  section  of

Results of Operations by Reporting Segment

In 2020, AltaGas revised its reportable segments to align with the structure of its business following asset sales completed as 

part  of  its  2019  asset  monetization  program. As  a  result  of  these  changes, AltaGas  has  refocused  on  its  core  Utilities  and 

Midstream  segments.  Consistent  with  Management’s  strategic  view  of  the  business  and  the  basis  on  which  it  assesses 

performance and allocates resources, beginning in 2020, AltaGas has two operating segments: Utilities (which now includes 

the  WGL  Retail  Marketing  business)  and  Midstream.  These  operating  segments  have  not  been  aggregated  in  the 

determination of AltaGas' reportable segments.

Service sites reflect all of the service sites of the utilities, including transportation and non‑regulated business lines. 
A degree day is a measure of coldness determined daily as the number of degrees the average temperature during the day in question is below 65 degrees 

Fahrenheit. Degree days for a particular period are determined by adding the degree days incurred during each day of the period. Normal degree days for a 

particular period are the average of degree days during the prior 15 years for SEMCO Gas, during the prior 10 years for ENSTAR, and during the prior 30 

years for Washington Gas.

In certain of Washington Gas’ jurisdictions (Virginia and Maryland) there are billing mechanisms in place that are designed to eliminate the effects of variance 

in  customer  usage  caused  by  weather  and  other  factors  such  as  conservation.  In  the  District  of  Columbia,  there  is  no  weather  normalization  billing 

mechanism nor does Washington Gas hedge to offset the effects of weather. As a result, colder or warmer weather will result in variances to financial results.

In U.S. dollars

During  the  fourth  quarter  of  2020,  AltaGas’  Utilities  segment  experienced  warmer  weather  at  SEMCO,  colder  weather  at 

ENSTAR, and warmer at Washington Gas compared to the same quarter of 2019.  

For the year ended December 31, 2020, AltaGas' Utilities segment experienced warmer weather at SEMCO, colder weather at 

ENSTAR, and warmer weather at Washington Gas compared to 2019.  

Service sites at December 31, 2020 increased by approximately 20 thousand sites compared to December 31, 2019 due to 

growth in customer base.

In the fourth quarter of 2020, U.S. Retail Energy Marketing gas sales volumes were 18,053 Mmcf, compared to 20,131 Mmcf 

in the same quarter of 2019. The decrease was primarily due to COVID-19 impacts. In the fourth quarter of 2020, U.S. Retail

Energy  Marketing  electricity  sales  volumes  were  3,257  GWh  compared  to  3,291  GWh  in  the  same  quarter  of  2019.  The 

decrease was primarily due to COVID-19 impacts, partially offset by an increase in customers served by the business.

For  the  year  ended  December  31,  2020,  U.S.  Retail  Energy  Marketing  gas  sales  volumes  were 59,782  Mmcf,  compared  to 

64,460  Mmcf  in  the  same  period  in  2019.  The  decrease  was  primarily  due  to  COVID-19  impacts.  For  the  year  ended 

December 31, 2020, U.S. Retail Energy Marketing electricity sales volumes were 13,607 GWh compared to 13,218 GWh in 

the same period in 2019. The increase was primarily due to an increase in customers served by the business, partially offset 

by COVID-19 impacts.

Three Months Ended December 31 

The Utilities segment reported normalized EBITDA of $259 million in the fourth quarter of 2020, compared to $260 million in 

the same quarter in 2019. Factors positively impacting normalized EBITDA included higher rates and gas margins at SEMCO, 

higher revenue from accelerated pipe replacement program spend, higher gas margins from WGL's Retail Energy Marketing 

business due to favorable pricing which was partially offset by COVID-19 impacts, and colder weather in Alaska. These were 

partially offset by the cancellation of late fees and related charges by the utilities due to COVID-19, the impact of the sale of 

ACI,  and  lower  power  margins  from  WGL's  Retail  Energy  Marketing  business  as  a  result  of  COVID-19  impacts  which  were 

partially  offset  by  lower  capacity  charges  in  2020,  higher  expenses  related  to  employee  benefits  and  incentive  plans,  a 

residential  energy  credit  adjustment  received  in  2019,  final  Virginia  rate  case  adjustments  in  2019,  and  warmer  weather  in 

Michigan.

Year Ended December 31  

The Utilities segment reported normalized EBITDA of $788 million in the year ended December 31, 2020, compared to $698 

million in 2019. The increase in normalized EBITDA was mainly due to the impact of Washington Gas' Maryland and Virginia 

rate cases, the impact of a change in accounting principle relating to Washington Gas' net periodic pension and other post-

retirement benefit plan costs (please refer to the Critical Accounting Estimates section of this MD&A for additional information), 

higher rates effective January 2020 at SEMCO due to the 2019 rate case application, higher revenue from accelerated pipe 

replacement program spend, colder weather in Alaska, lower operating expenses at WGL's Retail Energy Marketing business, 

and the favorable impact of the stronger U.S. dollar. This increase was partially offset by warmer weather in Michigan and in 

the  District  of  Columbia,  lower  customer  usage  primarily  as  a  result  of  COVID-19,  the  cancellation  of  late  fees  and  related 

charges  by  the  utilities  due  to  COVID-19,  lower  margins  from  WGL's  Retail  power  marketing  operations  as  a  result  of 

COVID-19  impacts  which  were  partially  offset  by  lower  capacity  charges  in  2020,  lower  margins  and  volumes  from  WGL's 

Retail gas marketing operations as a result of warmer weather and COVID-19 impacts which were partially offset by favorable 

pricing, and the impact of the sale of ACI. 

In 2020, the Utilities segment recognized a pre-tax gain of $206 million on the disposition of ACI. There were no dispositions in 

the Utilities segment in the year ended December 31, 2019.

COVID-19 Related Orders 

On  March  16,  2020,  the  Council  of  the  District  of  Columbia  (DC  Council)  passed  legislation  prohibiting  the  disconnection  of 

electric and gas services for non-payment of fees during a public health emergency. The Mayor of the District of Columbia's 

public health emergency declaration and all related orders have been further extended to March 31, 2021, and the prohibition 

on disconnection is effective for 15 days following the end of the public health emergency. On April 15, 2020, the PSC of DC 

issued an order authorizing Washington Gas to establish a regulatory asset to capture and track the incremental costs related 

to COVID-19 that were prudently incurred beginning March 11, 2020.

On  March  16,  2020,  the  Governor  of  Maryland  issued  an  Executive  Order  which  ordered  regulated  utilities  to  cease 

disconnections  and  billing  of  late  fees  for  residential  customers  through  May  1,  2020,  which  was  subsequently  amended  to 

extend the order through August 31, 2020. On September 22, 2020, the PSC of MD took action that had the effect of extending 

the  moratorium  on  service  disconnections  through  November  15,  2020.  Due  to  the  winter  moratorium  on  disconnections 

(November 1 to March 31), this has the effect of delaying residential terminations until April 1, 2021. On April 9, 2020, the PSC 

of MD issued an order and authorized each utility company to establish a regulatory asset to record the effects of incremental 

collection and other costs related to COVID-19 prudently incurred beginning on March 16, 2020. On August 27 and 28, 2020, 

the PSC of MD held Public Conference (PC) 53 to review the impacts of the Executive Order on utilities and the services they 

provide. On August 31, 2020, the PSC of MD issued an order directing that: (1) Utilities may not engage in service terminations 

and/or charge late fees until October 1, 2020 and any notices of termination for residential accounts sent before October 1, 

2020 are invalid; (2) a Public Service Company must give notice of at least 45 days before terminating service on a residential 

account; (3) structured payment plans offered by Public Service Companies to residential customers in arrears or unable to 

pay  must  allow  a  minimum  of  12  months  to  repay,  with  that  period  extending  to  24  months  for  customers  certified  as  low 

income; (4) Public Service Companies are prohibited from collecting or requiring down payments or deposits as a condition of 

beginning  a  payment  plan  by  any  residential  customer;  and  (5)  Public  Service  Companies  are  prohibited  from  refusing  to 

negotiate or denying a payment plan to a residential customer receiving service because the customer failed to meet the terms 

and  conditions  of  an  alternate  payment  plan  during  the  past  18  months. As  requested  by  the  PSC  of  MD,  investor-owned 

utilities  in  Maryland  filed  a  joint  proposed  Arrearage  Management  Program  (AMP)  plan  on  October  7,  2020,  which  was 

followed by a legislative style hearing in November 2020. On December 21, 2020, the PSC of MD rejected the proposed AMP 

plan. It will continue to monitor the customer arrearage data provided by utilities, and may revisit this issue in the future.

On  March  16,  2020,  the  State  Corporation  Commission  of  Virginia  (SCC  of  VA)  issued  an  order  which  prohibited 

disconnections  of  electricity,  gas,  water,  and  sewer  utility  services  during  the  coronavirus  public  health  emergency,  and 

established certain consumer protection measures. While the SCC of VA order was extended, the disconnection order, but not 

the consumer protections expired on October 5, 2020. However, following the expiration of the disconnection order, on October 

16,  2020,  the  Virginia  General  assembly  approved  legislation  that  would  extend  the  disconnection  prohibition  for  residential 

customers for nonpayment of bills or fees until the Governor determines the prohibition does not need to remain in place or 

until at least 60 days after the state of emergency declared on March 12, 2020 ends, whichever is sooner. The legislation also 

codified the consumer protection plans, requiring utilities to offer customers in arrears fee-free repayment plans without deposit 

or  eligibility  requirements. The  legislation  became  effective  in  November  2020.  On April  29,  2020,  the  SCC  of  VA  issued  an 

order approving a request from Washington Gas and other Virginia utilities to create a regulatory asset to record incremental 

prudently  incurred  costs  and  suspended  late  payment  fees  attributable  to  the  COVID-19  pandemic.  The  October  16,  2020 

legislation  approved  by  the  general  assembly  established  certain  reporting  requirements  for  utilities  to  report  bad  debt 

information  and  provides  utilities  with  certain  exemptions  from  such  requirements  based  on  a  utilities'  particular  facts  and 

circumstances.  On  December  8,  2020,  Washington  Gas  was  awarded  $US7.7  million  under  the  Virginia  CARES  Relief 

Funding Award, to use for customer arrearages. Virginia customers need to meet the criteria established by the program to get 

the funds. Any unused funds will be returned to the SCC of VA by December 10, 2021.

On April 10, 2020, the Governor of Alaska signed Senate Bill 241, which allows certificated utilities to record a regulatory asset 

for extraordinary costs and uncollectible residential utility bills that result from the COVID-19 public health disaster emergency 

declared  by  the  governor  on  March  11,  2020.  The  determination  as  to  whether  an  extraordinary  expense  resulted  from  the 

COVID-19 emergency is subject to approval by the RCA before recovery occurs through future rates. In response to Senate 

Bill 241, on April 15, 2020, the RCA opened an information docket to gather information including how utilities are dealing with 

COVID-19 and its effects. It will also discuss specific sections of Senate Bill 241 regarding deadlines for Commission actions 

and regulatory assets in a later public meeting.

On April 15, 2020, the MPSC issued an order for all utilities which allows for regulatory asset accounting to capture bad debts 

in  excess  of  what  is  in  approved  rates.  Incremental  cost  recovery  was  not  addressed  in  the  order;  however,  utilities  filed 

comments  and  reply  on  April  30,  2020  and  May  13,  2020,  respectively,  on  what  extraordinary  costs,  costs  savings,  and 

incremental  revenues  related  to  COVID-19  should  be  considered  by  the  MPSC  and  how  those  costs  should  be  tracked.  In 

addition, the order included a list of additional customer protection requirements. On July 23, 2020, the MPSC issued an order 

asking that any rate-regulated utility seeking recovery of COVID-19 related expenses beyond uncollectible expenses make an 

informational filing with the MPSC no later than November 2, 2020. SEMCO Gas did not establish a regulatory asset for bad 

debts since the bad debt expense is not expected to exceed the level approved in the last rate case proceeding. Furthermore, 

SEMCO  Gas  determined  that  the  benefit  would  be  de  minimis  to  proceed  with  filing  for  the  recovery  for  the  incremental 

COVID-19 costs considering the legal fees associated with completing such a regulatory filing.

fourth  quarter  of  2020,  compared  to  six  shipments  in  the  same  period  in  2019.  Propane  and  butane  export  volumes  at 

Ferndale averaged 33,979 Bbls/d, with two shipments to Asia for the period subsequent to close of the Petrogas Acquisition. 

Propane  volumes  exported  to Asia  at  RIPET  for  the  year  ended  December  31,  2020  averaged  39,285  Bbls/d  compared  to 

35,446 Bbls/d for the same period in 2019. There were 27 shipments during the year ended December 31, 2020 compared to 

15 shipments in the same period of 2019. Higher global export volumes and shipments were a result of RIPET operating for 

the  full  year  in  2020,  an  increase  in  the  amount  of  cargoes  sold  on  the  spot  market,  and  a  new  term  contract  effective 

September 2019. Propane and butane export volumes at Ferndale averaged 33,979 Bbls/d, with 2 shipments to Asia for the 

period subsequent to close of the Petrogas Acquisition. 

Inlet gas processing volumes for the fourth quarter of 2020 decreased by 4 Mmcf/d compared to the same quarter in 2019.  

Lower  inlet  gas  processing  volumes  in  the  fourth  quarter  of  2020  were  a  result  of  lower  inlet  volumes  at  Younger  due  to  a 

scheduled  turnaround  in  September  2020  which  was  extended  until  late  October,  and  lower  inlet  volumes  at  EEEP.  The 

decrease was partially offset by additional volumes from the newly constructed Townsend Deep Cut facility, which was placed 

in-service in May 2020, and higher inlet volumes at JEEP, Gordondale, and the Blair Creek facilities. 

Inlet gas processing volumes for the year ended December 31, 2020 decreased by 50 Mmcf/d compared to the same period in 

2019. Factors negatively impacting inlet gas processing volumes in the year ended December 31, 2020 included lower inlet 

volumes  at  the  extraction  facilities,  lower  take-or-pay  processed  volumes  at  the  Townsend  Shallow  Cut  facilities,  and  the 

disposal of certain non-core facilities in February 2019. The decrease was partially offset by volumes from the Townsend Deep 

Cut  facility,  which  was  placed  in-service  in  May  2020,  volumes  from  the  Nig  Creek  facility,  which  was  placed  in-service  in 

September 2019, and higher inlet volumes at the Gordondale facility.

Average ethane production volumes for the fourth quarter of 2020 increased by 4,815 Bbls/d, while average NGL production 

volumes increased by 1,886 Bbls/d compared to the same quarter in 2019. Higher ethane volumes were a result of additional 

contracted ethane volumes at the extraction facilities. Higher extracted NGL volumes were a result of additional extracted NGL 

volumes from the Townsend Deep Cut facility, which was placed in-service in May 2020, partially offset by lower inlet volumes 

at certain extraction facilities, primarily related to the Younger facility due to a planned turnaround, and lower inlet volumes at 

the Townsend Shallow Cut facilities.

Average  ethane  production  volumes  for  the year  ended  December  31,  2020  increased  by  4,192  Bbls/d,  while  average  NGL 

production  volumes  decreased  by  1,848  Bbls/d  compared  to  2019.  Higher  ethane  volumes  were  a  result  of  additional 

contracted ethane volumes at the extraction facilities. Lower extracted NGL volumes were a result of lower inlet volumes at the 

Townsend  Shallow  Cut  facilities  and  at  the  extraction  facilities,  mainly  related  to  the  Younger  facility,  partially  offset  by 

additional extracted NGL volumes from the Townsend Deep Cut facility which was placed in-service in May 2020.

Fractionation volumes for the fourth quarter of 2020 increased by 6,716 Bbls/d compared to the same quarter in 2019. Higher 

fractionation  volumes  were  a  result  of  the  North  Pine  expansion  and  additional  liquids  volumes  from  the  NEBC  facilities 

including  the  Townsend  Deep  Cut  facility.  The  increase  was  partially  offset  by  lower  trucked-in  volumes  at  Harmattan,  and 

lower extracted NGLs at Younger due to lower inlet and a turnaround in September that was extended until October.

Fractionation  volumes  for  the  year  ended  December  31,  2020  increased  by  3,400  Bbls/d  compared  to  the  same  period  in 

2019. Higher fractionation volumes were a result of the North Pine expansion and additional liquids volumes from the NEBC 

facilities.  The  increase  was  partially  offset  by  lower  trucked-in  volumes  at  Harmattan,  and  lower  extracted  NGLs  at  the 

Harmattan and Younger facilities due to lower inlet.

Natural gas optimization inventory as at December 31, 2020 was 39.3 Bcf (December 31, 2019 - 41.4 Bcf). The decrease in 

natural gas optimization inventory was primarily due to higher withdrawals of inventory in the fourth quarter of 2020 as a result 

of favorable natural gas prices.

 Three Months Ended December 31 

The Midstream segment reported normalized EBITDA of $128 million in the fourth quarter of 2020, compared to $179 million in 

the  same  quarter  in  2019. The  decrease  in  normalized  EBITDA  was  mainly  due  to  unfavorable  realized  storage  margins  at 

WGL Midstream, lower merchant volumes and realized margins at RIPET (inclusive of hedges), lower NGL marketing margins, 

lower realized frac spreads and exposed NGL volumes, and the impact of the sale of WGL Midstream's indirect non-operating 

interest  in  Central  Penn  in  November  2019.  These  were  partially  offset  by  contributions  from  Petrogas  for  the  period  after 

acquisition, higher tolling volumes at RIPET, higher processed volumes at the NEBC facilities, higher fractionation and liquids 

handling  revenues  due  to  NEBC  growth  projects  placed  into  service,  and  additional  contracted  ethane  volumes  at  the 

extraction  facilities.  During  the  fourth  quarter  of  2020,  for  the  period  prior  to  close  of  the  Petrogas  Acquisition,  AltaGas 

recorded equity earnings of $8 million from Petrogas compared to $31 million in the same quarter in 2019. Petrogas' export 

deliveries from Ferndale and volumes transacted through the terminals were at similar levels as in the fourth quarter of 2019. 

Industry  conditions  continued  to  impact  the  commodity  margins  and  activity  levels  in  Petrogas'  other  business  segments.  In 

addition,  in  the  fourth  quarter  of  2019,  Petrogas  earnings  included  a  large  one-time  payment  related  to  the  termination  of  a 

customer  contract.  On  December  15,  2020,  AltaGas  acquired  an  additional  37  percent  of  Petrogas,  resulting  in  AltaGas' 

ownership of Petrogas being increased to approximately 74 percent. As such, Petrogas' results have been consolidated for the 

period subsequent to close (please refer to the Acquisition of Petrogas section of this MD&A for additional information).

In the fourth quarter of 2020, the Midstream segment recognized a gain on it's previously held equity investment in AIJVLP of 

approximately $22 million, as well as a dilution loss and other adjustments to equity investments related to the acquisition of 

Petrogas  of  $26  million.  In  addition,  in  the  fourth  quarter  of  2020,  the  Midstream  segment  recognized  pre-tax  provisions  on 

assets of approximately $104 million ($79 million after-tax) primarily related to the Alton Natural Gas Storage Project. In the 

fourth  quarter  of  2019,  the  Midstream  segment  recognized  a  pre-tax  loss  of  approximately $12  million  on  the  disposition  of 

equity  investments,  primarily  related  to  WGL  Midstream's  indirect  non-operating  interest  in  Central  Penn.  In  addition,  in  the 

fourth quarter of 2019, the Midstream segment recognized a pre-tax provision of $34 million related to the Pouce Coupe sour 

gas treatment facility in Alberta.

sale of WGL Midstream's interest in Stonewall in May 2019, lower storage spreads and withdrawals at WGL Midstream due to 

lower commodity prices, lower NGL extracted and trucked in volumes, lower realized frac spreads (inclusive of hedges), and 

lower  NGL  marketing  margins. These  were  partially  offset  by  higher AFUDC  related  to  Mountain  Valley,  higher  fractionation 

and liquids handling revenues due to NEBC growth projects placed into service, higher processed volumes at certain NEBC 

facilities,  additional  contracted  ethane  volumes  at  the  extraction  facilities,  contributions  from  Petrogas  for  the  period  after 

acquisition, contributions from RIPET which was placed in-service in May 2019, and favorable transportation margins at WGL 

Midstream.  During  the  year  ended  December  31,  2020,  for  the  period  prior  to  close  of  the  Petrogas  Acquisition,  AltaGas 

recorded  equity  earnings  of  $29  million  from  Petrogas,  compared  to  $75  million  in  2019.  The  decrease  in  earnings  from 

Petrogas was primarily due to lower commodity prices in 2020, as well as the absence of a one-time payment related to the 

termination of a customer contract in the fourth quarter of 2019. On December 15, 2020, AltaGas acquired an additional 37 

percent  of  Petrogas,  resulting  in  AltaGas'  ownership  of  Petrogas  being  increased  to  approximately  74  percent.  As  such, 

Petrogas'  results  have  been  consolidated  for  the  period  subsequent  to  close  (please  refer  to  the  Acquisition  of  Petrogas 

section of this MD&A for additional information).

In  2020,  the  Midstream  segment  recognized  the  previously  mentioned  gain  on  the  re-measurement  of  it's  previously  held 

equity  investment  in  AIJVLP  of  approximately  $22  million  and  a  dilution  loss  and  other  adjustments  to  equity  investments 

related to the acquisition of Petrogas of $42 million. In 2020, the Midstream segment recognized pre-tax provisions on assets 

of approximately $106 million related to the previously mentioned provisions recognized in the fourth quarter of 2020 and land 

parcels  located  near  the  Harmattan  gas  processing  plant.  In  addition,  in  2020  the  Midstream  segment  recognized  a  pre-tax 

provision on equity investments of approximately $7 million related to the Constitution pipeline project which was cancelled in 

February  2020.  In  2019,  the  Midstream  segment  recognized  a  pre-tax  gain  of  $34  million  on  the  disposition  of  WGL 

Midstream's interest in Stonewall, a pre-tax gain of $5 million on the sale of certain non-core Midstream processing facilities, 

and  the  previously  mentioned  loss  on  equity  investments  recognized  in  the  fourth  quarter  of  2019.  In  2019,  the  Midstream 

segment  recognized  a  pre-tax  provision  on  equity  investments  of  approximately  $44  million  related  to  WGL  Midstream's 

indirect, non-operating interest in Central Penn which was sold in November 2019 and the previously mentioned provision on 

assets recognized in the fourth quarter of 2019.

Corporate/Other 

Three Months Ended December 31 

In the Corporate/Other segment, normalized EBITDA for the fourth quarter of 2020 was $5 million, compared to a loss of $3 

million in the same quarter in 2019. The increase was mainly due to earnings from WGL's remaining projects in its design build 

and  distributed  generation  business, which  was  partially  offset  by  the  impact  of  asset  sales,  including  Pomona  in  July  2020 

and Ripon in August 2020.

In the fourth quarter of 2019, the Corporate/Other segment recognized a pre-tax gain of $68 million on certain U.S. distributed 

generation projects which were sold in the third quarter of 2019 but transferred to the purchaser in the fourth quarter of 2019. 

In addition, in the fourth quarter of 2019, the Corporate/Other segment recognized pre-tax provisions of $380 million related to 

various long-lived assets. 

Year Ended December 31

In the Corporate/Other segment, normalized EBITDA for the year ended December 31, 2020 was $49 million, compared to $73 

million in 2019. The decrease was mainly due to the impact of asset sales, including the U.S. distributed generation assets in 

September 2019, certain non-core power assets in February 2019, the Northwest Hydro facilities in January 2019, Pomona in 

July 2020, Ripon in August 2020, and biomass investments in the third quarter of 2019, partially offset by recoveries related to 

CEWS,  earnings  from  WGL's  remaining  projects  in  its  design  build  and  distributed  generation  business,  a  shorter  planned 

spring  outage  at  the  Blythe  facility  compared  to  2019,  lower  employee  salary  expenses,  and  lower  expenses  related  to 

employee incentive plans as a result of the decreasing share price in 2020.

In 2020, the Corporate/Other segment recognized a pre-tax gain of $9 million on certain U.S. distributed generation projects 

which were sold in 2019 but transferred to the purchaser in 2020, a pre-tax gain of $5 million on the disposition of Pomona, 

and a pre-tax gain of $3 million on the disposition of Ripon. In addition, in 2020, the Corporate/Other segment recognized a 

pre-tax  provision  of  approximately  $3  million  related  to  certain  U.S.  distributed  generation  projects  which  had  not  yet 

transferred  to  the  purchaser.  In  2019,  the  Corporate/Other  segment  recognized  a  pre-tax  gain  of  $100  million  on  the 

disposition of the U.S. distributed generation assets, a pre-tax gain of $688 million on the sale of the remaining interest in the 

Northwest  Hydro  facilities,  a  pre-tax  loss  of  $6  million  on  the  sale  of  Canadian  non-core  power  assets,  a  pre-tax  loss  of 

$1  million  on  the  sale  of  a  WGL  Energy  Systems  financing  receivable,  and  the  previously  mentioned  gains  on  dispositions 

recorded  in  the fourth  quarter  of  2019.  In  addition,  in  2019,  the  Corporate/Other  segment  recognized  a  pre-tax  provision  on 

equity  investments  of  $2  million  related  to  biomass  investments  which  were  sold  in  the  third  quarter  of  2019,  a  pre-tax 

provision of $1 million related to a capital spare turbine in storage which was also sold in the third quarter of 2019, and the 

previously mentioned provisions on assets recognized in the fourth quarter of 2019.

During the fourth quarter of 2020, AltaGas’ invested capital was $1,087 million, compared to $260 million in the same quarter 

in 2019. The increase in invested capital was primarily due to cash paid for the Petrogas Acquisition, contributions to long-term 

investments, and higher additions to property, plant and equipment, partially offset by lower additions to intangible assets. 

The increase in additions to property, plant and equipment in the fourth quarter of 2020 was mainly due to capital expenditures 

related to system betterment and accelerated pipeline replacement programs at Washington Gas, construction costs related to 

the Nig Creek facility expansion project, and a turnaround at the Younger facility, partially offset by the absence of construction 

costs  related  to  the  Marquette  Connector  Pipeline  which  was  placed  in-service  in  December  2019,  and  the  absence  of 

construction costs relating to the NEBC pipeline projects, most of which were completed in the first half of 2020. The disposal 

of equity method investments in the fourth quarter of 2019 related to the disposition of Central Penn in November 2019.

The  invested  capital  in  the  fourth  quarter  of  2020  included  maintenance  capital  of  $18  million  (2019  ‑  $3  million)  in  the 
Midstream  segment  and  $nil  (2019  ‑  $1  million)  related  to  remaining  power  assets  in  the  Corporate/Other  segment. 
Maintenance capital incurred in the fourth quarter of 2020 primarily related to the turnaround at the Younger facility.

$ 

During the year ended December 31, 2020, AltaGas’ invested capital was $1.8 billion, compared to $1.5 billion in 2019. The 

increase  in  invested  capital  was  primarily  due  to  cash  paid  for  the  Petrogas  Acquisition,  lower  contributions  from  non-

controlling interests, and a capital contribution made to AIJVLP related to a cash call in the first quarter of 2020, partially offset 

by  lower  additions  to  property,  plant  and  equipment,  and  lower  contributions  to  WGL's  equity  investments  in  the  Mountain 

Valley pipeline, and Central Penn which was sold in November 2019. 

The  decrease  in  additions  to  property,  plant  and  equipment  in  the  year  ended  December  31,  2020  was  mainly  due  to  the  

absence of construction costs related to RIPET which was placed in-service in May 2019, the absence of construction costs 

related  to  Nig  Creek  which  was  placed  in-service  September  2019,  the  absence  of  capital  expenditures  related  to  the  U.S. 

distributed  generation  assets  which  were  sold  in  September  2019,  lower  capital  expenditures  related  to  the  Townsend  2B 

expansion, North Pine expansion, and NEBC pipeline projects which were placed in-service in the first half of 2020, and the 

absence  of  construction  costs  related  to  the  Marquette  Connector  Pipeline  which  was  placed  in-service  in  December  2019. 

These were partially offset by increased expenditures related to the accelerated pipeline replacement programs at Washington 

Gas and SEMCO, and construction of the Nig Creek expansion project. The disposals of property, plant and equipment in the 

year  ended  December  31,  2020  primarily  related  to  the  remaining  proceeds  received  from  the  disposition  of  the  U.S. 

distributed  generation  assets  and  the  disposition  of  Pomona  and  Ripon  in  the  third  quarter  of  2020.  In  the  year  ended 

December  31,  2019,  disposals  of  property,  plant  and  equipment  primarily  related  to  the  disposition  of  the  U.S.  distributed 

generation assets, the Northwest Hydro facilities, and non-core Canadian Midstream and Power assets. The disposal of equity 

method investments in the year ended December 31, 2020 related to the disposition of ACI, while in the year ended December

31,  2019  the  disposals  of  equity  method  investments  related  to  the  disposition  of  Stonewall,  biomass  investments,  and  the 

previously mentioned disposal of Central Penn in the fourth quarter of 2019. 

The invested capital for the year ended December 31, 2020 included maintenance capital of $22 million (2019 ‑ $6 million) in 
the  Midstream  segment  and  $14  million  (2019  ‑  $20  million)  related  to  remaining  power  assets  in  the  Corporate/Other 
segment.  The  increase  in  maintenance  capital  for  the  Midstream  segment  was  primarily  due  to  increased  turnaround 

expenditures. The decrease in maintenance capital for the Corporate/Other segment was primarily due to lower maintenance 

expenditures at the Blythe facility.

Risk Management 

Risks Related to COVID-19

As the COVID-19 pandemic continues, governments in the jurisdictions where AltaGas operates have maintained measures 

designed  to  contain  the  outbreak,  including  business  closures  and  restrictions,  travel  limitations  and  border  closings, 

quarantines,  and  restrictions  on  gatherings  and  events.  The  magnitude,  outcome,  and  duration  of  the  pandemic  remains 

uncertain. As a result, it is not currently possible to accurately quantify the total potential impact of the pandemic on AltaGas’ 

operations or financial results.

AltaGas,  with  its  subsidiaries,  activated  its  pandemic  response  team  to  monitor  developments  related  to  COVID-19  and  to 

ensure  the  Corporation  was  responding  swiftly  and  appropriately.  Continuity  plans  and  preparedness  measures  have  been 

implemented  at  each  of AltaGas’  businesses,  with  safeguarding  the  well-being  of  its  personnel  as  the  primary  concern.  To 

date, AltaGas  has  been  able  to  respond  to  the  COVID-19  related  challenges  with  minimal  disruption  to  its  operations  and 

business.

AltaGas has identified the following as potential direct or indirect impacts to its business and operations from the pandemic:

▪

Key employees and personnel: Widespread inability of AltaGas' workforce or that of the Corporation's contractors to 

perform their duties would have an adverse impact on AltaGas' ability to continue normal operations in the Utilities, 

Midstream and Corporate/Other segments. To date, AltaGas has not experienced unavailability of a significant portion 

of its personnel as a result of COVID-19 related concerns;

▪

Return  to  work:  As  AltaGas  reintegrates  its  personnel  to  its  workplace,  it  may  incur  additional  costs  to  adapt  the 

workplace to meet applicable health and safety requirements. Shortages in personal protective equipment (PPE), the 

occurrence of additional waves of the virus, or delays in the availability or rollout of vaccines may require AltaGas to 

revise or delay such reintegration plans. To the extent that it is unable to effectively protect its workforce against the 

transmission of the virus, AltaGas may be forced to slow or reverse its reintegration efforts and could face allegations 

of liability;

▪

IT  infrastructure,  privacy  and  cyber  security:  Increased  volume  and  sophistication  of  targeted  cyber-attacks  have 

been  seen  since  the  declaration  of  the  global  pandemic.  Pandemic-adjusted  operations,  such  as  work  from  home 

arrangements  and  remote  access  to  the  Corporation's  systems,  may  pose  heightened  risk  of  cyber  security  and 

privacy breaches and may put additional stress on the Corporation's IT infrastructure. A failure of such infrastructure 

could  severely  limit  AltaGas'  ability  to  conduct  ordinary  operations.  To  date,  AltaGas’  systems  have  functioned 

capably, and it has not experienced a material impact to its operations as a result of an IT infrastructure issue;

▪

Adverse impacts on market fundamentals and access to capital: AltaGas has seen an impact from COVID-19 related 

factors  in  relation  to  lower  margins  in  the  Retail  Energy  Marketing  business,  cancellation  of  late  fees  and  related 

charges along with the inability to disconnect customers, impacts to income from Petrogas due to lower commodity 

prices,  and increased cost with regard to COVID-19 related costs to the business. The impact of these factors was 

not material to AltaGas' 2020 financial performance and is currently not expected to be material to the 2021 financial 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 45

 
performance of AltaGas. While access to capital could be negatively impacted by the global impact of the virus, at this 

point, AltaGas anticipates that it has adequate access to capital to execute its 2021 business plans; and

▪

Counterparty and supplier risk: increased exposure that contract counterparties and suppliers could fail to meet their 

obligations to AltaGas. Such non-performance by a significant counterparty or supplier could adversely affect AltaGas' 

operations and financial results. To date, any cases of force majeure invoked by counterparties related to the AltaGas’ 

assets as a result of COVID-19 have not been material.

To  the  extent  these  risks  materialize,  the  Corporation’s  ability  to  carry  out  its  business  plans  for  2021  may  be  adversely 

impacted.

Political Uncertainty and Civil Unrest

Uncertainty exists with regard to the political climate in the jurisdictions where AltaGas operates. Changes in social, political, 

regulatory, or economic conditions, or in laws and policies governing environment, development, tax, foreign trade, investment 

or energy could materially adversely affect AltaGas' business and operations.

Recently there have been significant incidents of civil unrest in areas where AltaGas operates. To the extent that civil unrest is 

accompanied  by  disruption  to  transportation  routes,  damage  to  infrastructure,  violence  or  destruction,  AltaGas'  personnel, 

physical facilities, and operations may be placed at risk and financial and operational results may be adversely impacted.

Other

AltaGas  is  exposed  to  various  market  risks  in  the  normal  course  of  operations  that  could  impact  earnings  and  cash  flows. 

AltaGas  enters  into  physical  and  financial  derivative  contracts  to  manage  exposure  to  fluctuations  in  commodity  prices  and 

foreign  exchange  rates,  as  well  as  to  optimize  certain  owned  and  managed  natural  gas  assets.  The  Board  of  Directors  of 

AltaGas  has  established  a  risk  management  policy  for  the  Corporation  establishing  AltaGas’  risk  management  control 

framework.  Derivative  instruments  are  governed  under,  and  subject  to,  this  policy.  As  at  December  31,  2020  and 

December 31, 2019, the fair values of the Corporation’s derivatives were as follows:

The Corporation executes gas, power, LPG, crude oil, ocean freight, and other physical and financial commodity contracts to 

serve its customers as well as manage and optimize its asset portfolio. A portion of these physical contracts are not recorded 

at fair value because they are either: 1) designated as “normal purchases and normal sales”; 2) do not qualify as derivative 

instruments  due  to  the  significance  of  their  notional  amount  relative  to  the  applicable  liquid  markets;  or  3)  are  weather 

derivatives, which are not exchanged or traded and the underlying variables relate to a climactic, geological, or other physical 

variable. The fair value of commodity contracts that qualify as derivatives was calculated using estimated forward prices based 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 46

 
 
 
 
 
 
 
on  published  sources  for  the  relevant  period. AltaGas  has  not  elected  hedge  accounting  for  any  of  its  derivative  contracts 

currently in place. For AltaGas’ Midstream segment, changes in the fair value of these derivative contracts are recorded in the 

Consolidated  Statements  of  Income  in  the  period  in  which  the  change  occurs.  For  the  Utilities  segment,  changes  in  the  fair 

value  of  derivative  instruments  recoverable  or  refundable  to  customers  are  recorded  to  regulatory  assets  or  regulatory 

liabilities  on  the  Consolidated  Balance  Sheets,  while  changes  in  the  fair  value  of  derivative  instruments  not  affected  by  rate 

regulation are recorded in the Consolidated Statements of Income in the period in which the change occurs. The Midstream 

segment also executes fixed-for-floating NGL frac spread swaps to manage exposure to frac spreads as the financial results of 

several extraction plants are affected by fluctuations in NGL frac spreads.

▪

The average indicative spot NGL frac spread for the year ended December 31, 2020 was approximately $5/Bbl (2019 

– $11/Bbl), inclusive of basis differentials. The average NGL frac spread realized by AltaGas (based on average spot 

price  and  realized  hedge  price  inclusive  of  basis  differentials)  for  the  year  ended  December  31,  2020  was 

▪

▪

approximately $14/Bbl inclusive of basis differentials (2019 - $17/Bbl). 

For 2021, AltaGas estimates an average of approximately 9,000 Bbls/d of NGL will be exposed to frac spreads prior 

to  hedging  activities.  Hedges  are  in  place  for  approximately  97  percent  of  frac  exposed  NGL  volumes  including 

internal hedges.  

At  RIPET,  propane  price  margins  are  protected  through  AltaGas'  comprehensive  hedging  program.  Approximately 

one  third  of  2021  expected  volumes  are  contracted  under  tolling  arrangements.  For  the  remaining  volumes, 

approximately  67  percent  are  financially  hedged  at  an  FEI  to  Mont  Belvieu  spread  of  approximately  US$10/

Bbl. Approximately 80 percent of RIPET’s propane export volumes are hedged for 2021.

▪

At Ferndale, AltaGas is exposed to the propane and butane price differentials between North American Indices and 

the  Far  East  Index  for  contracts  not  under  tolling  arrangements  or  naturally  hedged  supply  agreements.  AltaGas 

estimates an average of approximately 32,000 Bbls/d will be exposed to these price differentials in 2021. To date for 

2021, AltaGas has hedges in place for approximately 12 percent of these exposed propane and butane volumes at an 

average FEI to Conway spread of US$14/Bbl for propane and at an average FEI to purchase price spread of US$28/

Bbl  for  butane.  AltaGas  estimates  that  an  average  of  approximately  9,000  Bbls/d  or  21  percent  of  2021  forecast 

exports from Ferndale are under tolling arrangements or naturally hedged supply agreements.

Additionally,  AltaGas  uses  physical  and  financial  derivatives  for  the  purchase  and  sale  of  natural  gas  in  order  to  optimize 

owned storage and transportation capacity as well as manage transportation and storage assets on behalf of third parties. 

The Utilities segment enters into hedging contracts and other contracts that may qualify as derivative instruments related to the 

purchase  of  natural  gas  to  manage  price  risk  for  its  ratepayers.  Additionally,  Washington  Gas  executes  commodity-related 

physical and financial contracts in the form of forward, futures, and option contracts as part of an asset optimization program. 

Under  this  program,  Washington  Gas  realizes  value  from  its  long-term  natural  gas  transportation  and  storage  capacity 

resources when they are not being fully used to serve utility customers. Additionally, to serve retail customers, AltaGas enters 

into both physical and financial contracts for the purchase and sale of electricity and natural gas. 

The Corporate/Other segment has various fixed-for-floating power purchase and  sale  contracts  in  the Alberta market,  which 

are expected to be settled over the next three years.

Foreign Exchange Contracts

AltaGas  is  exposed  to  foreign  exchange  risk  as  changes  in  foreign  exchange  rates  may  affect  the  fair  value  or  future  cash 

flows  of  the  Corporation’s  financial  instruments. AltaGas  has  foreign  operations  whereby  the  functional  currency  is  the  U.S. 

dollar.  As  a  result,  the  Corporation’s  earnings,  cash  flows,  and  other  comprehensive  income  are  exposed  to  fluctuations 

resulting  from  changes  in  foreign  exchange  rates.  This  risk  is  partially  mitigated  to  the  extent  that AltaGas  has  U.S.  dollar-

denominated debt and/or preferred shares outstanding. AltaGas may also enter into foreign exchange forward derivatives to 

manage the risk of fluctuating cash flows due to variations in foreign exchange rates.

As at December 31, 2020, Management has not designated any outstanding U.S. dollar denominated long-term debt 

to hedge against the currency translation effect of its foreign investments (December 31, 2019 - US$300 million).

For the year ended December 31, 2020, AltaGas incurred an after-tax unrealized loss of $9 million arising from the 

translation of debt in other comprehensive income (2019 - after-tax unrealized gain of $60 million). 

In  connection  with  the  Petrogas Acquisition  (please  refer  to  the  Acquisition  of  Petrogas  section  of  this  MD&A  for  additional 

information),  AltaGas  acquired  various  commodity  and  financial  derivative  instruments,  including  the  following  foreign 

exchange contracts which are outstanding as at December 31, 2020:

For  the  year  ended  December  31,  2020, AltaGas  recorded  an  after-tax  realized  gain  of  $1  million  on  all  foreign  exchange 

forward contracts. 

Interest Rate Contracts

AltaGas  is  exposed  to  interest  rate  risk  as  changes  in  interest  rates  may  impact  future  cash  flows  and  the  fair  value  of  its 

financial instruments. The Corporation manages its interest rate risk by holding a mix of both fixed and floating interest rate 

debt. 

From time to time, AltaGas may concurrently draw on its credit facility in U.S. dollars and enter into cross currency basis swaps 

whereby,  on  final  settlement,  AltaGas  receives  U.S.  dollars  from  the  counterparty  and  pays  Canadian  dollars  to  the 

counterparty. As  a  result, AltaGas  reduces  its  interest  expense  by  taking  advantage  of  the  interest  rate  spread  between  the 

Banker's Acceptance (BA) rate and the London Inter-bank Offered Rate (LIBOR) without any additional foreign exchange risk.

Weather Instruments

WGL  Energy  Services  utilizes  heating  degree  day  (HDD)  instruments  from  time  to  time  to  manage  weather  and  price  risks 

related  to  its  natural  gas  and  electricity  sales  during  the  winter  heating  season.  WGL  Energy  Services  also  utilizes  cooling 

degree day (CDD) instruments and other instruments to manage weather and price risks related to its electricity sales during 

the  summer  cooling  season.  These  instruments  cover  a  portion  of  estimated  revenue  or  energy-related  cost  exposure  to 

variations  in  HDDs  or  CDDs.  For  the  year  ended  December  31,  2020,  a  pre-tax  loss  of  $3  million  (2019  -  pre-tax  loss  of 

$2 million) was recorded related to heating degree day (HDD) and cooling degree day (CDD) instruments.

Liquidity

As  a  result  of  certain  commitments  made  to  the  PSC  of  DC,  the  PSC  of  MD,  and  the  SCC  of  VA  in  respect  of  the  WGL 

Acquisition, Washington Gas is subject to certain restrictions when paying dividends to AltaGas. However, AltaGas does not 

expect that this will have an impact on AltaGas’ ability to meet its obligations.

In addition, Wrangler SPE LLC and Washington Gas made certain ring fencing commitments to the PSC of DC, the PSC of 

MD, and the SCC of VA with the intention of removing Washington Gas from the bankruptcy estate of AltaGas and its affiliates, 

other  than  Washington  Gas  and  Wrangler  SPE  LLC  (together,  the  “Ring  Fenced  Entities”).  Because  of  these  ring  fencing 

measures, none of the assets of the Ring Fenced Entities would be available to satisfy the debt or contractual obligations of 

AltaGas or any non-Ring Fenced Entity Affiliate, including any indebtedness or other contractual obligations of AltaGas, and

Cash from operations increased by $156 million for the year ended December 31, 2020 compared to 2019, primarily due to 

higher  net  income  after  taxes  (after  adjusting  for  non-cash  items)  and  favorable  variances  in  the  net  change  in  operating 

assets and liabilities, partly offset by lower distributions from equity investments. The majority of the variance in net change in 

operating assets and liabilities was due to increased cash flows from accounts payable and accrued liabilities driven by asset 

sales  and  fluctuations  in  volumes  and  prices,  and  increased  cash  flows  related  to  other  current  assets  due  to  lower  cash 

collateral  posted  with  counterparties  and  lower  prepaid  expenses.  These  increases  were  partially  offset  by  decreased  cash 

flows  from  accounts  receivable  due  to  fluctuations  in  commodity  prices  and  sales  volumes,  regulatory  assets  and  liabilities 

primarily  due  to  overall  warmer  weather  experienced  by  the  Utilities  segment,  refunds  of  certain  regulatory  liabilities  to 

customers, and increases in non-weather related regulatory liabilities.

The increase in the working capital ratio was primarily due to increases in in accounts receivable, and decreases in short-term 

debt  and  the  current  portion  of  long-term  debt,  partially  offset  by  increases  in  accounts  payable  and  accrued  liabilities,  and 

decreases in prepaid expenses and other assets. AltaGas’ working capital will fluctuate in the normal course of business. The 

working capital deficiency is expected to be funded using cash flow from operations and available credit facilities as required. 

Investing Activities

Cash  used  in  investing  activities  for  the  year  ended  December  31,  2020  was  $1.2  billion,  compared  to  cash  from  investing 

activities  of  $2.2  billion  in  2019.  Investing  activities  for  the  year  ended  December  31,  2020  primarily  included  the  cash 

payment,  net  of  cash  acquired,  of  $675  million  for  the  Petrogas Acquisition,  expenditures  of  approximately  $843  million  for 

property, plant, and equipment and intangible assets, $75 million related to the change in loan to an affiliate, and approximately 

$72  million  of  contributions  to  equity  investments,  which  were  partially  offset  by  proceeds  of  $4  million  from  the  sale  of 

investments in publicly-traded entities, $376 million from the disposition of equity investments (primarily for the disposition of 

ACI),  and  proceeds  of  $74  million  from  the  disposition  of  assets  (net  of  transaction  costs).  Investing  activities  for  the  year 

ended  December  31,  2019  included  proceeds  of  $3.6  billion  from  asset  sales  completed  in  2019  (including  the  Northwest 

Hydro  facilities,  distributed  generation  assets,  Central  Penn,  Stonewall,  biomass  assets,  and  non-core  Canadian  Midstream 

and Power assets) and proceeds of $73 million from the sale of a WGL Energy Systems financing receivable, partially offset by

expenditures  of  approximately $1.3  billion  for  property,  plant,  and  equipment  and  intangible  assets,  and  approximately $179 

million of contributions to equity investments. 

Financing Activities 

Cash from financing activities for the year ended December 31, 2020 was $392 million, compared to cash used in financing 

activities of $2.9 billion in 2019. Financing activities for the year ended December 31, 2020 were primarily comprised of net 

repayments of short-term debt and repayments of long-term debt of $1.2 billion, dividends of $334 million, $200 million for the 

redemption  of  Series  I  Preferred  Shares,  and  distributions  to  non-controlling  interests  of $28  million,  partially  offset  by  debt 

issuances of $2.0 billion, net issuances under credit facilities of $191 million, and contributions from non-controlling interests of 

$7 million. Financing activities for the year ended December 31, 2019 were primarily comprised of net repayments of short-

term debt and repayments of long-term debt of $1.6 billion, net repayments under credit facilities of $1.9 billion, dividends of 

$334  million,  distributions  to  non-controlling  interests  of  $13  million,  and  the  redemption  of  preferred  shares  of  $38  million, 

partially  offset  by  debt  issuances  of  $889  million,  net  proceeds  from  the  issuance  of  common  shares  of  $68  million  and 

contributions  from  non-controlling  interests  of  $48  million.  Total  dividends  paid  to  common  and  preferred  shareholders  of 

AltaGas for the year ended December 31, 2020 were $334 million (2019 - $334 million), of which $6 million was reinvested 

through the DRIP (2019 - $68 million). Beginning with the January dividend paid on February 17, 2020, dividend payments are 

no longer eligible for reinvestment by participating shareholders under the DRIP.

Capital Resources 

AltaGas' objective for managing capital is to maintain its investment grade credit ratings, ensure adequate liquidity, optimize 
the profitability of its existing assets, and grow its energy infrastructure to create long‑term value and enhance returns for its 
investors. AltaGas'  capital  structure  is  comprised  of  shareholders'  equity  (including  non‑controlling  interests),  short‑term  and 
long‑term debt (including the current portion) less cash and cash equivalents.

The use of debt or equity funding is based on AltaGas’ capital structure, which is determined by considering the norms and 

risks associated with operations and cash flow stability and sustainability.

For  the  purposes  of  the  net  debt  calculation,  short-term  debt  excludes  third-party  project  financing  obtained  on  behalf  of  the  United  States  federal 

government  to  provide  funds  for  the  construction  of  certain  energy  management  services  projects.  As  this  debt  was  obtained  on  behalf  of  the  U.S. 

government, AltaGas would only need to repay in the event that the project is not completed or accepted by the government. See Note 15 of the 2020 Annual 

Consolidated Financial Statements for additional details. At December 31, 2020, the project financing balance excluded from short-term debt in above table 

was $20 million (December 31, 2019 - $71 million). 

(2) Net of debt issuance costs of $43 million as at December 31, 2020 (December 31, 2019 - $36 million).  

As  at  December  31,  2020, AltaGas’  total  debt  primarily  consisted  of  outstanding  medium-term  notes  (MTNs)  of  $4.0  billion 

(December  31,  2019  -  $3.0  billion),  WGL  and  Washington  Gas  long-term  debt  of  $2.1  billion  (December  31,  2019  -  $2.4 
billion),  reflecting  fair  value  adjustments  on  acquisition,  SEMCO  long‑term  debt  of  $641  million  (December  31,  2019  -  $466 
million), $934 million drawn under the bank credit facilities (December  31, 2019 -  $643 million) and short-term debt  of $256 

million (December 31, 2019 - $460 million). In addition, AltaGas had $230 million of letters of credit outstanding (December 31, 

2019 - $307 million). 

As  at  December  31,  2020, AltaGas’  total  market  capitalization  was  approximately  $5.2  billion  based  on  approximately  279 

million common shares outstanding and a closing trading price on December 31, 2020 of $18.72 per common share.

AltaGas'  earnings  interest  coverage  for  the  rolling  twelve  months  ended December  31,  2020  was  2.8  times  (twelve  months 

ended December 31, 2019 – 3.2 times).

WGL and Washington Gas use short-term debt in the form of commercial paper or unsecured short-term bank loans to fund 

seasonal  cash  requirements.  Revolving  committed  credit  facilities  are  maintained  in  an  amount  equal  to  or  greater  than  the 

expected maximum commercial paper position. As at December 31, 2020, commercial paper outstanding totaled $495 million 

for WGL and Washington Gas (December 31, 2019 – $757 million).

All of the borrowing facilities have covenants customary for these types of facilities, which must be met at each quarter end. 

AltaGas and its subsidiaries have been in compliance with all financial covenants each quarter since the establishment of the 

facilities.  AltaGas  and  its  subsidiaries  are  also  in  compliance  with  trust  indenture  requirements  for  its  MTNs  as  at 

December 31, 2020 and December 31, 2019.

The following table summarizes the Corporation's primary financial covenants as defined by the credit facility agreements:

(4) WGL’s bank debt-to-capitalization ratio is calculated based on WGL’s consolidated financial statements. 

On  September  25,  2019,  a  $2.0  billion  base  shelf  prospectus  for  the  issuance  of  certain  types  of  future  public  debt  and/or 

equity  issuances  was  filed.  This  enables AltaGas  to  access  the  Canadian  capital  markets  on  a  timely  basis  during  the  25-

month  period  that  the  base  shelf  prospectus  remains  effective.  As  at  December  31,  2020,  approximately  $0.3  billion  was 

available under the base shelf prospectus. 

On February 22, 2021, a $2.5 billion base shelf prospectus for the issuance of certain types of future public debt and/or equity 

issuances  was  filed  to  replace  the  base  shelf  prospectus  dated  September  25,  2019.  This  enables AltaGas  to  access  the 

Canadian capital markets on a timely basis during the 25-month period that the base shelf prospectus remains effective.

On  January  21,  2020, AltaGas  filed  a  US$2.0  billion  short  form  base  shelf  prospectus  in  both Alberta  and  the  U.S. This  will 

enable  AltaGas  to  access  the  U.S.  capital  markets  during  the  25-month  period  that  the  base  shelf  prospectus  remains 

effective. As  at  December  31,  2020,  US$2.0  billion  was  available  under  the  base  shelf  prospectus.  On  February  22,  2021, 

AltaGas filed a US$2.0 billion short form base shelf prospectus in both Alberta and the U.S. to replace the US$2.0 billion short 

form base shelf prospectus filed on January 21, 2020.

According to the S&P rating system, an obligor rated BBB has adequate protection parameters. However, adverse economic 

conditions  or  changing  circumstances  are  more  likely  to  lead  to  a  weakened  capacity  of  the  obligor  to  meet  its  financial 

commitments. The  ratings  from AA  to  CCC  may  be  modified  by  the  addition  of  a  plus  (+)  or  minus  (-)  sign  to  show  relative 

standing within the major rating categories. A P-3 rating by S&P is the third highest of eight categories granted by S&P under 

its  Canadian  preferred  share  rating  scale  and  a  P-3  rating  directly  corresponds  with  a  BB  rating  under  its  global  preferred 

rating scale. The Canadian preferred share rating scale is fully determined by the global preferred rating scale and there are 

no  additional  analytical  criteria  associated  with  the  determination  of  ratings  on  the  Canadian  preferred  share  rating  scale. 

According to the S&P rating system, while securities rated P-3 are regarded as having significant speculative characteristics, 

they  are  less  vulnerable  to  non-payment  than  other  speculative  issues.  However,  it  faces  major  ongoing  uncertainties  or 

exposure to adverse business, financial, or economic conditions which could lead to the obligor’s inadequate capacity to meet 

its  financial  commitment  on  the  obligation.  The  ratings  from  P-1  to  P-5  may  be  modified  by  "high"  and  "low"  grades  which 

indicate relative standing within the major rating categories.

AltaGas Ltd. – 2020 MD&A and Financial Statements - 58

According to the DBRS rating system, debt securities rated BBB are of adequate credit quality. The capacity for the payment of 

financial  obligations  is  considered  acceptable,  but  may  be  vulnerable  to  future  events.  "High"  or  "Low"  grades  are  used  to 

indicate the relative standing within a particular rating category. A Pfd-3 rating by DBRS is the third highest of six categories 

granted  by  DBRS. According  to  the  DBRS  rating  system,  preferred  shares  rated  Pfd-3  are  of  adequate  credit  quality.  While 

protection of dividends and principal is still considered acceptable, the issuing entity is more susceptible to adverse changes in 

financial  and  economic  conditions,  and  there  may  be  other  adversities  present  which  detract  from  debt  protection.  Pfd-3 

ratings  normally  correspond  with  companies  whose  bonds  are  rated  in  the  higher  end  of  the  BBB  category.  "High"  or  "Low" 

grades are used to indicate the relative standing within a rating category. The absence of either a "High" or "Low" designation 

indicates the rating is in the middle of the category.

According to the Fitch rating system, ‘BBB’ ratings indicate that expectations of default risk are currently low. The capacity for 

payment  of  financial  commitments  is  considered  adequate,  but  adverse  business  or  economic  conditions  are  more  likely  to 

impair this capacity. A ‘BB’ rating by Fitch indicates an elevated vulnerability to default risk, particularly in the event of adverse 

changes  in  business  or  economic  conditions  over  time;  however,  business  or  financial  flexibility  exists  that  support  the 

servicing of financial commitments.

According  to  the  Moody’s  rating  system,  Baa  ratings  indicate  moderate  credit  risk.  Obligations  rated  Baa  are  considered 

medium-grade and as such may possess speculative characteristics.     

The  credit  ratings  accorded  to  the  securities  by  the  rating  agencies  are  not  recommendations  to  purchase,  hold,  or  sell  the 

securities  in  as  much  as  such  ratings  do  not  comment  as  to  market  price  or  suitability  for  a  particular  investor. There  is  no 

assurance that any rating will remain in effect for any given period of time or that any rating will not be revised or withdrawn 

entirely by a rating agency in the future if, in its judgment, circumstances so warrant.

Since  a  determination  of  the  value  of  many  assets,  liabilities,  revenues  and  expenses  is  dependent  upon  future  events,  the 

preparation  of AltaGas'  Consolidated  Financial  Statements  requires  the  use  of  estimates  and  assumptions  that  have  been 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 61

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
made  using  careful  judgment.  AltaGas’  significant  accounting  policies  are  contained  in  the  notes  to  the  2020  Annual 

Consolidated  Financial  Statements.  Certain  of  these  policies  involve  critical  accounting  estimates  as  a  result  of  the 

requirement to make particularly subjective or complex judgments about matters that are inherently uncertain, and because of 

the likelihood that materially different amounts could be reported under different conditions or using different assumptions.

Significant  estimates and judgments made by Management  in  the preparation of the Consolidated Financial Statements  are 

outlined below: 

Regulatory Assets and Liabilities

SEMCO Gas, ENSTAR and Washington Gas engage in the delivery and sale of natural gas. SEMCO Gas and ENSTAR are 

regulated by the MPSC and RCA, respectively. Washington Gas is regulated by the PSC of DC in the District of Columbia, the 

PSC of MD in Maryland, and the SCC of VA in Virginia.

The  regulatory  agencies  exercise  statutory  authority  over  matters  such  as  tariffs,  rates,  construction,  operations,  financing, 

returns and certain contracts with customers. In order to recognize the economic effects of the actions and decisions of the 

regulators,  the  timing  of  recognition  of  certain  assets,  liabilities,  revenues  and  expenses  as  a  result  of  regulation  may  differ 

from that otherwise expected using U.S. GAAP for entities not subject to rate regulation. 

Regulatory assets represent future revenues associated with certain costs incurred in the current period or in prior periods that 

are expected to be recovered from customers in future periods through the rate-setting process. Regulatory liabilities represent 

future reductions or limitations of increases in revenue associated with amounts that are expected to be refunded to customers 

through the rate-setting process.

Asset Impairment

AltaGas reviews long-lived assets, regulatory assets, and intangible assets with indefinite and finite lives whenever events or 

changes in circumstances indicate that the carrying value of such assets may not be recoverable. Recoverability is determined 

based on an estimate of undiscounted cash flows or other indicators of fair value, and measurement of an impairment loss is 

determined based on the fair value of the assets. The determination of fair value requires Management to make assumptions 

about future cash inflows and outflows over the life of an asset. Any changes to the assumptions used for the future cash flow 

could result in revisions to the evaluation of the recoverability of the long-lived assets or intangible assets and the recognition 

of an impairment loss in the Consolidated Financial Statements.  

AltaGas also tests goodwill for impairment annually or more frequently if events or changes in circumstances indicate that it is 

more likely than not that the fair value of a reporting unit is less than its carrying value. The Corporation has the option to first 

assess  qualitative  factors  to  determine  whether  it  is  necessary  to  perform  the  quantitative  goodwill  impairment  test.  If  the 

quantitative  goodwill  impairment  test  is  performed,  the  fair  value  of  the  Corporation’s  reporting  units  is  compared  to  the 

carrying values. If the carrying value of a reporting unit, including allocated goodwill exceeds its fair value, goodwill impairment 

is measured as the excess of the carrying value amount of the reporting unit’s allocated goodwill over the implied fair value of 

the goodwill. The fair value used in the quantitative impairment test of goodwill requires estimating future cash flows as well as 

appropriate discount rates. AltaGas has assessed goodwill for impairment as at December 31, 2020 and determined that no 

write-down was required. 

Asset Retirement Obligations 

AltaGas records liabilities relating to asset retirement obligations when there is a legal obligation. In estimating the obligations, 

Management  is  required  to  make  assumptions  regarding  inflation  and  discount  rates,  ultimate  amounts  and  timing  of 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 62

settlements,  and  expected  changes  in  environmental  laws  and  regulation. A  change  in  any  of  these  estimates  could  have  a 

material impact on AltaGas' Consolidated Financial Statements.

Income Taxes

The Corporation is subject to the provisions of the Income Tax Act (Canada) for purposes of determining the amount of income 

that  will  be  subject  to  tax  in  Canada  and  the  Internal  Revenue  Code  (U.S.)  for  the  purposes  of  determining  the  amount  of 

income that will be subject to tax in the United States. The determination of AltaGas’ and its subsidiaries’ provision for income 

taxes requires the application of these complex rules. 

Substantial deferred income tax assets and liabilities are recognized in the Consolidated Financial Statements. The recognition 

of  deferred  tax  assets  depends  on  the  assumption  that  future  earnings  will  be  sufficient  to  realize  the  deferred  benefit.  A 

valuation allowance is recorded against deferred tax assets where all or a portion of that asset is not expected to be realized. 

The  amount  of  the  deferred  tax  asset  or  liability  recorded  is  based  on  Management’s  best  estimate  of  the  timing  of  the 

realization of the assets or liabilities. 

If Management’s interpretation of tax legislation differs from that of tax authorities, or if timing of reversals is not as anticipated, 

the  provision  for  income  taxes  could  increase  or  decrease  in  future  periods.  See  Note 20  of  the  2020 Annual  Consolidated 

Financial Statements.

Pension Plans and Post-Retirement Benefits

The  determination  of  pension  plan  obligations  and  expense  is  based  on  a  number  of  actuarial  assumptions.  Critical 

assumptions  include  the  expected  long-term  rate-of-return  on  plan  assets,  the  discount  rate  applied  to  pension  plan 

obligations, the expected rate of compensation increase, and mortality rates. For post-retirement benefit plans, which provide 

for certain health care premiums and life insurance benefits for qualifying retired employees and which are not funded, critical 

assumptions in determining post-retirement obligations and expense are the discount rate and the assumed health care cost 

trend rates. 

In the third quarter of 2020, AltaGas made a voluntary change in accounting principle for calculating the market-related value 

of assets (MRVA) used in the determination of Washington Gas' net periodic pension and other post-retirement benefit plan 

costs  This  change  in  accounting  principle  impacts  the  calculation  of  net  periodic  benefit  cost  recorded  within  the  line  item 

“other  income”  on  the  Consolidated  Statements  of  Income  (Loss).  The  change  uses  the  fair  value  approach  for  the  fixed 

income investment asset class of the plan assets, compared to the prior method that utilized a calculated value where gains 

and losses arising from changes in fair value were deferred and amortized into the calculation of the MRVA over a period of 

five  years. The  MRVA  is  used  in  the  calculation  of  the  expected  return  on  assets  and  the  recognized  actuarial  gain  or  loss 

components  of  net  periodic  benefit  cost.  The  approach  applied  for  all  other  classes  of  assets  remains  unchanged. 

Management  believes  that  using  the  fair  value  approach  for  the  fixed  income  investments  in  plan  assets  is  preferable  as  it 

more  closely  aligns  the  recognition  of  related  components  within  the  net  periodic  benefit  cost. The  quantitative  effect  of  this 

change in accounting principle was not considered material to prior periods or the current year; therefore, an increase to net 

income (loss) applicable to common shares of approximately $19 million was recognized in 2020.

Notes 2 and 28 of the 2020 Annual Consolidated Financial Statements include information on the assumptions used for the 

purposes of recording the funding status of the plans and the associated expenses.

Depreciation and Amortization 

Depreciation and amortization of property, plant, and equipment and intangible assets are based on Management’s judgment 

of the estimated useful life of the assets. When it is determined that assigned asset lives do not reflect the estimated remaining 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 63

period of benefit, prospective changes are made to the depreciable lives of those assets. For regulated entities, amortization 

rates are generally prescribed by the applicable regulatory authority. There are a number of uncertainties inherent in estimating 

the remaining useful life of certain assets and changes in assumptions could result in material adjustments to the amount of 

amortization that AltaGas recognizes from period to period. 

Loss Contingencies

AltaGas and its subsidiaries are subject to various legal claims and actions arising in the normal course of business. Liabilities 

for loss contingencies are determined on a case-by-case basis and are accrued for when it is probable that a liability has been 

incurred and the amount can be reasonably estimated. Significant judgment is required to determine the probability of having 

incurred the liability and the estimated amount. Estimates are reviewed regularly and updated as new information is received. 

As at December 31, 2020, no material provisions on loss contingencies have been recorded by the Corporation. However, due 

to the inherent uncertainty of the litigation process, the resolution of any particular contingencies could have a material adverse 

effect on the Corporation’s results of operations or financial position. 

Fair Value of Financial Instruments

Fair value is defined as the amount of consideration that would be agreed upon in an arms-length transaction, other than a 

forced sale or liquidation, between knowledgeable, willing parties who are under no compulsion to act. The best evidence of 

fair value is a quoted bid or ask price, as appropriate, in an active market. Fair value based on unadjusted quoted prices in an 

active  market  requires  minimal  judgment  by  Management.  Where  bid  or  ask  prices  in  an  active  market  are  not  available, 

Management’s  judgment  on  valuation  inputs  is  necessary  to  determine  fair  value. AltaGas  enters  into  physical  and  financial 

derivative contracts to manage exposure to fluctuations in commodity prices and foreign exchange rates, as well as to optimize 

certain owned  and managed natural gas assets. AltaGas estimates forward prices based on published sources adjusted  for 

factors specific to the asset or liability, including basis and location differentials, discount rates, and currency exchange. The 

forward  curves  used  to  mark  these  derivative  instruments  to  market  are  vetted  against  public  sources.  Where  observable 

market data is not available, AltaGas uses valuation techniques which require significant judgment by Management. Changes 

in estimates and assumptions about these inputs could affect the reported fair value.

Adoption of New Accounting Standards 

Effective  January  1,  2020, AltaGas  adopted  the  following  Financial Accounting  Standards  Board  (FASB)  issued Accounting 

Standards Updates (ASU):

§

In  June  2016,  FASB  issued ASU  No.  2016-13  “Financial  Instruments  –  Credit  Losses  and  all  related  amendments 

(collectively  "ASC  326"):  Measurement  of  Credit  Losses  on  Financial  Instruments”.  The  ASU  replaces  the  current 

“incurred  loss”  impairment  methodology  with  an  “expected  loss”  model  for  financial  assets  measured  at  amortized 

cost. AltaGas has applied ASC 326 using the modified retrospective approach through a cumulative-effect adjustment 

to retained earnings as of the effective date of the new standard. Prior periods presented for comparative purposes 

were not adjusted. Upon adoption of ASC 326, "accounts receivable, net of allowances" decreased by $2 million and 

"long-term investments and other assets" decreased by $5 million, with an offsetting increase to "accumulated deficit". 

AltaGas has elected to account for its cash equivalents at fair value. Please also refer to Note 23 of the Consolidated 

Financial statements as at and for the year ended December 31, 2020 for further details;

§

ASU  No.  2018-13  “Fair  Value  Measurement  –  Disclosure  Framework:  Changes  to  the  Disclosure  Requirements  for 

Fair  Value  Measurement”.  The  amendments  in  this  ASU  modify  the  disclosure  requirements  on  fair  value 

measurements.  The  adoption  of  this  ASU  did  not  have  a  material  impact  on  AltaGas’  consolidated  financial 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 64

statements, but resulted in certain minor adjustments to the fair value disclosures. Please also refer to Note 23 of the 

Consolidated Financial statements as at and for the year ended December 31, 2020 for further details; 

§

ASU  No.  2018-14  “Compensation-Retirement  Benefits-Defined  Benefit  Plans  –  General:  Disclosure  Framework  – 

Changes  to  the  Disclosure  Requirements  for  the  Defined  Benefit  Plans”.  The  amendments  in  this ASU  modify  the 

disclosure requirements on defined benefit pension and other post-retirement plans. The adoption of this ASU did not 

have  a  material  impact  on  AltaGas'  consolidated  financial  statements,  but  resulted  in  certain  modifications  to  the 

disclosures in the pension footnote. Please also refer to Note 28 of the Consolidated Financial statements as at and 

for the year ended December 31, 2020 for further details.

§

ASU  No.  2018-17  “Consolidation: Targeted  Improvements  to  Related  Party  Guidance  for  Variable  Interest  Entities”. 

The amendments in this ASU provide a private-company scope exception to the VIE guidance for certain entities and 

clarify  that  indirect  interests  held  through  related  parties  under  common  control  are  considered  on  a  proportional 

basis  when  determining  whether  fees  paid  to  decision  makers  and  service  providers  are  variable  interests.  The 

adoption of this ASU did not have a material impact on AltaGas’ consolidated financial statements; 

§

ASU  No.  2018-18  "Collaborative  Arrangements:  Clarifying  the  Interaction  between  Topic  808  and  Topic  606".  The 

amendments in this ASU clarifies that certain transactions between collaborative arrangement participants should be 

accounted  for  as  revenue  under ASC  606,  adds  unit-of-account  guidance  in ASC  808  to  align  with  the  guidance  in 

ASC  606,  and  requires  that  a  transaction  with  a  collaborative  arrangement  participant  that  is  not  directly  related  to 

sales to third parties, is precluded from presenting the transaction together with revenue recognized under ASC 606 if 

the collaborative arrangement participant is not a customer. The adoption of this ASU did not have a material impact 

on AltaGas’ consolidated financial statements;  

§

ASU No. 2019-01 "Leases: Codification Improvements". The amendments in this ASU provide a fair value exception 

for  lessors  that  are  not  manufacturers  or  dealers,  clarifies  the  presentation  of  principal  payments  received  under 

sales-type  and  direct  finance  leases  for  depository  and  lending  institutions,  and  clarifies  that  interim  transition 

disclosure requirements related to the change on income statement, net income and related per share amounts for 

the  adoption  of  ASC  842  are  not  required.  The  adoption  of  this  ASU  did  not  have  a  material  impact  on  AltaGas’ 

consolidated financial statements; 

§

ASU  No.  2019-04  “Financial  Instruments:  Codification  Improvements".  The  amendments  in  this  ASU  provide 

clarification  and  improve  the  codification  in  recently  issued  accounting  standards  relating  to  credit  losses,  hedge 

accounting,  and  financial  instruments. The  amendments  related  to  credit  losses  were  evaluated  in  conjunction  with 

ASU  2016-13  above.  The  adoption  of  this ASU  did  not  have  a  material  impact  on AltaGas’  consolidated  financial 

statements; and 

§

ASU  No.  2020-03  "Codification  Improvements  to  Financial  Instruments".  The  amendments  in  this  ASU  provide 

clarification and improve the codification to certain aspects of accounting standards related to financial instruments. 

The adoption of this ASU did not have a material impact on AltaGas’ consolidated financial statements. 

Effective December 31, 2020, AltaGas adopted the following FASB issued ASU:

§	 ASU  No.  2018-14  “Compensation-Retirement  Benefits-Defined  Benefit  Plans  –  General:  Disclosure  Framework  – 

Changes  to  the  Disclosure  Requirements  for  the  Defined  Benefit  Plans”.  The  amendments  in  this ASU  modify  the 

disclosure requirements on defined benefit pension and other post-retirement plans. The adoption of this ASU did not 

have  a  material  impact  on  AltaGas'  consolidated  financial  statements,  but  resulted  in  certain  modifications  to  the 

disclosures in the pension footnote. Please also refer to Note 28 of the Consolidated Financial statements as at and 

for the year ended December 31, 2020 for further details.

Future Changes in Accounting Principles

In  December  2019,  FASB  issued  ASU  No.  2019-12  "Income  Taxes:  Simplifying  the  Accounting  for  Income  Taxes".  The 

amendments  in  this  ASU  simplify  the  accounting  for  income  taxes  by  clarifying  certain  aspects  of  current  guidance  and 

removing  some  exceptions  to  the  general  principles  in ASC  740. The  amendments  in  this ASU  are  effective  for  fiscal  years 

beginning after December 15, 2020, and interim periods within those fiscal years. The adoption of this ASU is not expected to 

have a material impact on AltaGas’ financial statements. 

In  January  2020,  FASB  issued ASU  No.  2020-01  "Derivatives  and  Hedging:  Clarifying  the  Interactions  between  Topic  321, 

Topic  323,  and  Topic  815".  The  amendments  in  this  ASU  clarify  the  application  of  the  measurement  alternative  for  equity 

instruments  and  the  measurement  of  non-derivative  forward  contracts  or  purchased  call  options  used  to  acquire  equity 

securities. The amendments in this ASU are effective for fiscal years beginning after December 15, 2020, and interim periods 

within those fiscal years. Early adoption is permitted. The adoption of this ASU is not expected to have a material impact on 

AltaGas’ financial statements. 

In March 2020, FASB issued ASU No. 2020-04 "Reference Rate Reform: Facilitation of the Effects of Reference Rate Reform 

on  Financial  Reporting."  The  amendments  in  this  ASU  provide  optional  expedients  and  exceptions  for  applying  GAAP  to 

contract modifications and hedging relationships affected by reference rate reform if certain criteria are met. These apply only 

to  contracts,  hedging  relationships,  and  other  transactions  that  reference  LIBOR  or  another  reference  rate  expected  to  be 

discontinued  because  of  reference  rate  reform.  The  amendments  in  this  ASU  are  effective  as  of  March  12,  2020  through 

December 31, 2022. AltaGas may elect to apply the amendments as of any date from the beginning of an interim period that 

includes  or  is  subsequent  to  March  12,  2020  on  a  prospective  basis.  AltaGas  has  not  elected  to  adopt  this  ASU  as  of 

December 31, 2020, and is assessing the impact of this ASU on its consolidated financial statements. 

In August 2020, FASB issued ASU No. 2020-06 "Debt with Conversion and Other Options and Topic 815-40 - Derivatives and 

Hedging - Contracts in Entity's Own Equity: Accounting for Convertible Instruments and Contract in an Entity's Own Equity." 

The amendments in this Update simplify the accounting for certain financial instruments with characteristics of liabilities and 

equity, including convertible instruments and contracts in an entity’s own equity. The amendments in this Update are effective 

for  public  business  entities  that  meet  the  definition  of  a  Securities  and  Exchange  Commission  (SEC)  filer,  excluding  entities 

eligible  to  be  smaller  reporting  companies  as  defined  by  the  SEC,  for  fiscal  years  beginning  after  December  15,  2021, 

including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning 

after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted. The adoption of this 

ASU is not expected to have a material impact on AltaGas' financial statements. 

Off-Balance Sheet Arrangements

AltaGas is not party to any contractual arrangements with unconsolidated entities that have, or are reasonably likely to have, a 

current or future material effect on the Corporation’s financial performance or financial condition including liquidity and capital 

resources. 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 66

Disclosure Controls and Procedures (DCP) and Internal Control Over Financial Reporting (ICFR) 

Management,  including  the  Chief  Executive  Officer  and  Chief  Financial  Officer,  are  responsible  for  establishing  and 
maintaining DCP and ICFR, as those terms are defined in National Instrument 52‑109 "Certification of Disclosure in Issuers' 
Annual and Interim Filings". The objective of this instrument is to improve the quality, reliability, and transparency of information 

that is filed or submitted under securities legislation.

Management, including the Chief Executive Officer and the Chief Financial Officer, have designed, or caused to be designed 

under their supervision, DCP and ICFR to provide reasonable assurance that information required to be disclosed by AltaGas 

in its annual filings, interim filings or other reports to be filed or submitted by it under securities legislation is made known to 

them, is reported on a timely basis, financial reporting is reliable, and financial statements prepared for external purposes are 

in accordance with U.S. GAAP.

The ICFR has been designed based on the framework established in the 2013 Internal Control ‑ Integrated Framework issued 
by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

Management  has  designed  the  existing  framework  to  result  in  both  a  complete  and  accurate  consolidation  of  related 

information. During the year ended December 31, 2020, other than changes in ICFR related to the Petrogas Acquisition, there 

were no changes made to AltaGas' ICFR that materially affected, or are reasonably likely to materially affect, its ICFR or DCP. 
AltaGas does not believe that process changes adopted in connection with the COVID‑19 pandemic have materially affected 
ICFR. 

The  Chief  Executive  Officer  and  the  Chief  Financial  officer  have  evaluated,  with  the  assistance  of AltaGas'  employees,  the 

effectiveness of AltaGas' DCP and ICFR as at December 31, 2020 and concluded that as at December 31, 2020 AltaGas' DCP 

and ICFR were effective. 

Limitation on Scope

In accordance with the provisions under National Instrument 52-109, and consistent with SEC-related guidance, the scope of 

the evaluation does not include ICFR related to Petrogas, which was acquired on December 15, 2020. These provisions allow 

an issuer to exclude a business which was acquired not more than 365 days before the issuer's financial year-end from the 

scope  of  its  certifications. As  such,  the  controls,  policies,  and  procedures  related  to  the  Petrogas Acquisition  were  excluded 

from management's evaluation of the effectiveness of AltaGas' ICFR as at December 31, 2020.  Summary financial information 

of  Petrogas  included  in  the  audited  Consolidated  Financial  Statements  as  at  and  for  the  year  ended  December  31,  2020, 

includes total assets of approximately $2.6 billion and revenues of approximately $143 million. 

It  should  be  noted  that  a  control  system,  no  matter  how  well  conceived  and  operated,  can  provide  only  reasonable,  not 

absolute,  assurance  that  the  objectives  of  the  control  system  are  met.  Because  of  the  inherent  limitations  in  all  control 

systems, no evaluation of controls can provide absolute assurance that all control issues, including instances of fraud, if any, 

have been detected. The design of any system of controls is also based in part on certain assumptions about the likelihood of 

future events, and there can be no assurances that any design will succeed in achieving its stated goals under all potential 

conditions.

Beginning in 2020, Management no  longer  adjusts normalized EBITDA for changes in the fair value of natural  gas optimization inventory.  Please see the 

Non-GAAP Financial Measures section of this MD&A for additional detail. Prior periods have been adjusted to reflect the impact of this change. 

AltaGas’ quarter-over-quarter financial results are impacted by seasonality, fluctuations in commodity prices, weather, the U.S./

Canadian  dollar  exchange  rate,  planned  and  unplanned  plant  outages,  timing  of  in-service  dates  of  new  projects,  and 

acquisition and divestiture activities. 

Revenue for the Utilities is generally the highest in the first and fourth quarters of any given year as the majority of natural gas 

demand occurs during the winter heating season, which typically extends from November to March. 

Other significant items that impacted quarter-over-quarter revenue during the periods noted include: 

§ 

§ 

The seasonally colder weather experienced at several of the utilities in the second and third quarters of 2020;

The impact of the sale of the Northwest Hydro facilities and non-core Canadian Midstream and Power assets in the 

first quarter of 2019;

§   RIPET entering commercial service in the second quarter of 2019;

§   The impact of the sale of the U.S. distributed generation assets in the third quarter of 2019; 

§   The impact of the sale of AltaGas Pomona Energy Storage Inc. and AltaGas Ripon Energy Inc. in the third quarter of 

2020; and

§   The impact of the acquisition of additional equity interest in Petrogas in the fourth quarter of 2020.

Net income (loss) applicable to common shares is also affected by non-cash items such as deferred income tax, depreciation 

and amortization expense, accretion expense, provisions on assets, gains or losses on long-term investments, and gains or 

losses on the sale of assets. In addition, net income (loss) applicable to common shares is also impacted by preferred share 

dividends  and  gains  or  losses  on  the  redemption  of  preferred  shares.  For  these  reasons,  net  income  (loss)  may  not 

necessarily reflect the same trends as revenue. Net income (loss) applicable to common shares during the periods noted was 

impacted by: 

§ 

Lower depreciation and amortization expense due to the impact of asset sales, partially offset by new assets placed 

into service;

§  After-tax  transaction  costs  of  approximately  $18  million  and  $10  million  incurred  throughout  2020  and  2019, 

respectively, due to asset sales; 

§		The impact of the sale of the Northwest Hydro facilities and non-core Canadian Midstream and Power assets in the 

first quarter of 2019;

§   The impact of the sale of the U.S. distributed generation assets in the third quarter of 2019; 

§    The  impact  of  the  sale  of  WGL  Midstream's  indirect  non-operating  interest  in  Central  Penn  in  the  fourth  quarter  of 

2019; 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 68

 
 
 
 
 
§   After-tax provisions of approximately $319 million recognized in the fourth quarter of 2019, primarily related to Power 

assets;

§   The impact of the sale of ACI in the first quarter of 2020; 

§   The impact of the sale of AltaGas Pomona Energy Storage Inc. and AltaGas Ripon Energy Inc. in the third quarter of 

2020; 

§   The impact of the acquisition of additional equity interest in Petrogas in the fourth quarter of 2020;

§    The  after-tax  provision  of  approximately  $79  million  recognized  in  the  fourth  quarter  of  2020  related  to  the  Alton 

Natural Gas Storage Project; and

§    The  impact  of  the  change  in  accounting  principle  relating  to  Washington  Gas'  net  periodic  pension  and  other  post-

retirement benefit plan costs in the third quarter of 2020.

MANAGEMENT'S REPORT  

The Consolidated Financial Statements of AltaGas Ltd. (AltaGas or the Corporation) and other financial information included in 

this report are the responsibility of Management. The Consolidated Financial Statements have been prepared by Management 

in accordance with United States Generally Accepted Accounting Principles (U.S. GAAP) and include amounts that are based 

on Management’s best estimates and judgments.  It is  Management's responsibility to ensure that judgments, estimates and 

accounting  principles  and  methods  used  in  the  preparation  of  financial  information  are  reasonable,  appropriate,  and  applied 

consistently. 

Management's Report on Internal Control Over Financial Reporting

Management  is  responsible  for  establishing  and  maintaining  adequate  internal  controls  over  financial  reporting  for  the 

Corporation (as defined in Rules 13a-15(f) of the Securities Exchange Act and under National Instrument 52-109). 

Management  has  used  the  framework  established  in  the  2013  Internal  Control  ‑  Integrated  Framework  issued  by  the 
Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (COSO)  to  evaluate  the  effectiveness  of  the 

Corporation's  internal  control  over  financial  reporting.  Based  on  this  evaluation,  Management,  including  the  CEO  and  CFO, 

has concluded that the Corporation's internal control over financial reporting is effective as at December 31, 2020.

In accordance with the provisions under National Instrument 52-109, and consistent with SEC-related guidance, the scope of 

the evaluation does not include Internal Control over Financial Reporting (ICFR) related to Petrogas Energy Corp. (Petrogas), 

which was acquired on December 15, 2020. As such, the controls, policies, and procedures related to the Petrogas Acquisition 

were  excluded  from  management's  evaluation  of  the  effectiveness  of  AltaGas'  ICFR  as  at  December  31,  2020.  Summary 

financial  information  of  Petrogas  included  in  the  audited  Consolidated  Financial  Statements  as  at  and  for  the  year  ended 

December 31, 2020, includes total assets of approximately $2.6 billion and revenues of approximately $143 million.

Internal  control  over  financial  reporting  may  not  prevent  all  misstatements  due  to  its  inherent  limitations.  In  addition,  the 

evaluation of internal control was made as of a specific date and continued effectiveness in future periods is subject to the risk 

that controls may become inadequate. 

The  Board  of  Directors  is  responsible  for  ensuring  that  Management  fulfills  its  responsibilities  for  financial  reporting  and 

internal  controls.  The  Board  is  assisted  in  carrying  out  its  responsibilities  principally  through  its  Audit  Committee  which  is 

composed  of  independent  non-management  directors.  The  Audit  Committee  meets  with  Management  regularly  and  meets 

independently  with  internal  and  external  auditors  and  as  a  group  to  review  any  significant  accounting,  internal  controls,  and 

auditing matters in accordance with the terms of the Charter of the Audit Committee, which is set out in the Annual Information 

Form.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Shareholders of AltaGas Ltd. 

Opinion on the Consolidated Financial Statements 

We  have  audited  the  accompanying  consolidated  financial  statements  of AltaGas  Ltd.  (the  “Company”),  which  comprise  the 

consolidated balance sheets as at December 31, 2020 and 2019, and the consolidated statements of income, comprehensive 

income (loss), equity and cash flows for each of the years then ended, and the related notes (collectively referred to as the 

“consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, 

the financial position of AltaGas Ltd as at December 31, 2020 and 2019, and the results of its operations and its cash flows for 

each of the years then ended, in conformity with United States generally accepted accounting principles.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company‘s management. Our responsibility is to express 

an  opinion  on  the  Company‘s  consolidated  financial  statements  based  on  our  audits.  We  are  a  public  accounting  firm 

registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent 

with respect to the Company in accordance with the US 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. The Company is not required to have, nor were we engaged to perform, an audit 

of  its  internal  control  over  financial  reporting. As  part  of  our  audits,  we  are  required  to  obtain  an  understanding  of  internal 

control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal 

control over financial reporting. Accordingly, we express no such opinion. 

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  include 

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 Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that 

were communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures 

that  are  material  to  the  financial  statements  and  (2)  involved  especially  challenging,  subjective  or  complex  judgements. The 

communication of critical audit matters 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 matters below, providing a separate opinion on the critical audit 

matters or on the accounts or disclosures to which it relates. 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 73

Description of the 
Matter

Fair Value Measurement of Level 3 Derivatives

As described in Note 23 to the financial statements, AltaGas Ltd. enters into commodity contracts that 

qualify  as  derivative  instruments  and  are  accounted  for  under  ASC  Topic  815,  Derivatives  and 

Hedging. The fair value measurements of certain of these contracts are considered Level 3 under the 

fair value hierarchy as they are determined using significant unobservable inputs. As of December 31, 

2020, derivative assets of $69 million and derivative liabilities of $162 million were recorded based on 

Level 3 fair value measurements.

Auditing  the  fair  value  measurement  of  Level  3  derivative  instruments  was  complex  given  the 

judgmental  nature  of  the  assumptions  used  as  inputs  into  the  valuation  models.  In  particular,  the 

valuation of Level 3 derivative instruments is sensitive to significant unobservable inputs used by the 

Company such as the assumed natural gas basis prices and implied volatilities of natural gas prices. 

These unobservable assumptions could be affected by future economic and market conditions.

How We Addressed 
the Matter in Our 
Audit

To test the valuation of Level 3 derivative instruments, our audit procedures included, among others, 

evaluating  the  valuation  methodologies  used  by  the  Company  and  testing  significant  inputs, 

assumptions and the mathematical accuracy of the calculations. In certain instances, with involvement 

of  our  valuation  specialists,  we  independently  determined  the  significant  unobservable  assumptions 

described above, calculated the resulting fair values and compared them to the Company’s estimates. 

For a sample of instruments, we obtained forward prices from independent sources, including broker 

quotes, evaluated the Company’s assumptions related to their forward curves and obtained external 

confirmation of key contract terms from counterparties. We also performed sensitivity analyses using 

independent  sources  of  market  data  to  evaluate  the  change  in  fair  value  of  Level  3  derivative 

instruments that would result from changes in underlying assumptions.

Acquisition of Additional Interest in Petrogas Energy Corp. (“Petrogas”)

Description of the 
Matter

On December 15, 2020, the Group acquired an additional 37% equity interest in Petrogas for a total 

consideration  of  approximately  $715  million  as  noted  in  Note  3  of  the  consolidated  financial 

statements. The Group now owns a controlling interest in Petrogas of approximately 74%. Business 

combinations that are achieved in stages are accounted for using the acquisition method as per ASC 

805 - Business Combinations. The purchase price allocation is preliminary and reflects management’s 

best estimate of the fair value of Petrogas’ assets and liabilities based on the analysis of information 

obtained to date.

Auditing the business combination was complex given the significant degree of estimation uncertainty 

that  is  inherent  in  the  preliminary  nature  of  the  purchase  price  allocation. Additionally,  management 

was required to exercise significant judgment when determining their best estimate of the fair value of 

the  previously  held  equity  interest,  the  identified  assets  and  labilities  of  Petrogas,  and  the  non-

controlling  interest  attributed  to  the  minority  shareholder.  These  valuations  are  sensitive  to  future 

estimated cash flows and discount rates.

AltaGas Ltd. – 2020 MD&A and Financial Statements - 74

How We Addressed 
the Matter in Our 
Audit

To  test  the  Group’s  preliminary  purchase  price  allocation,  we  performed  the  following  procedures, 

among  others:  Read  the  applicable  agreements  to  obtain  an  understanding  of  the  key  terms  and 

conditions  of  the  acquired  additional  interest  to  identify  the  necessary  accounting  considerations; 

Assessed  the  competency,  objectivity,  and  independence  of  management’s  external  valuation 

specialists;  Involved  our  valuation  specialists  to  assess  the  valuation  methodology  applied  with 

respect  to  intangibles,  non-controlling  interest,  previously  held  interest,  and  goodwill.  They  also 

assessed management’s approach to quantifying the preliminary discount rates utilised by referencing 

current industry, economic, and comparable company information, as well as company and cash-flow 

specific risk premiums; Assessed the appropriateness of the preliminary future estimated cash flows 

by  comparing  management’s  underlying  assumptions  to  historical  Petrogas  data  and  the  respective 

contractual terms and conditions; Involved our capital equipment specialists to review selected third-

party  appraisals  to  assess  the  appropriateness  of  management’s  best  estimate  of  the  fair  value  of 

property, plant, and equipment; and evaluated the adequacy of the related disclosure included in Note 

3 of the accompanying consolidated financial statements

Regulatory Accounting

Description of the 
Matter

As discussed in Note 21 to the financial statements, AltaGas Ltd. accounts for its regulated operations 

in accordance with Accounting Standards Codification Topic 980, Regulated Operations. As such, the 

Company defers certain costs as regulatory assets and records them as expenses on its statements 

of operations as it collects the revenue designed to recover these costs through customers’ rates. The 

Company  also  records  regulatory  liabilities  for  gains  previously  realized  or  for  amounts  previously 

collected  from  customers  for  expenses  expected  to  be  incurred  in  the  future.  As  of  December  31, 

2020,  the  Company  recorded  $490  million  of  regulatory  assets  and  $1,471  million  of  regulatory 

liabilities.

Auditing  the  Company’s  regulatory  assets  and  liabilities  was  complex  due  to  significant  judgments 

made by management to support its assertions about the probability of both the recovery of regulatory 

assets and the refund of regulatory liabilities. In particular, there was subjectivity involved in assessing 

the impact of current and future regulatory orders on events that have occurred as of December 31, 

2020 and judgment required to evaluate the relevance and reliability of audit evidence to support the 

probability  of  recovery  in  future  rates  of  incurred  costs  or  refunds  to  customers. These  assumptions 

have  a  significant  effect  on  the  recorded  amounts  of  regulatory  assets  and  liabilities,  operating 

revenues and expenses, and related disclosures.

How We Addressed 
the Matter in Our 
Audit

We  performed  audit  procedures  that  included,  among  others,  evaluating  the  reasonableness  of  the 

Company’s  assessment  of  the  probability  of  the  recovery  of  the  regulatory  assets  and  the  refund  of 

regulatory  liabilities.  For  example,  we  evaluated  the  Company’s  correspondence  with  the  regulatory 

commissions, status of regulatory proceedings, past practices, and recent rate orders issued to other 

regulated  entities  in  the  same  jurisdictions.  In  addition,  we  evaluated  the  Company’s  related 

disclosures.

We have served as AltaGas Ltd. auditor since 1997.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS 

(Tabular amounts and amounts in footnotes to tables are in millions of Canadian dollars unless otherwise indicated.)

1.   Organization and Overview of the Business 

The businesses of AltaGas are operated by the Company and a number of its subsidiaries including, without limitation, AltaGas 

Services  (U.S.)  Inc., AltaGas  Utility  Holdings  (U.S.)  Inc.,  WGL  Holdings,  Inc.  (WGL),  Wrangler  1  LLC,  Wrangler  SPE  LLC, 

Washington  Gas  Resources  Corporation,  WGL  Energy  Services,  Inc.  (WGL  Energy  Services),  and  SEMCO  Holding 

Corporation; in regard to the Utilities business, Washington Gas Light Company (Washington Gas), Hampshire Gas Company, 

and  SEMCO  Energy,  Inc.  (SEMCO);  in  regard  to  the  Midstream  business,  AltaGas  Extraction  and  Transmission  Limited 

Partnership,  AltaGas  Pipeline  Partnership,  AltaGas  Processing  Partnership,  AltaGas  Northwest  Processing  Limited 

Partnership,  Harmattan  Gas  Processing  Limited  Partnership,  Ridley  Island  LPG  Export  Limited  Partnership,  and  WGL 

Midstream Inc. (WGL Midstream); and, in regard to remaining assets in the Corporate/Other segment, AltaGas Power Holdings 

(U.S.)  Inc.,  WGL  Energy  Systems,  Inc.  (WGL  Energy  Systems),  and  Blythe  Energy  Inc.  (Blythe).  SEMCO  conducts  its 

Michigan natural gas distribution business under the name SEMCO Energy Gas Company (SEMCO Gas), its Alaska natural 

gas distribution business under the name ENSTAR Natural Gas Company (ENSTAR) and its 65 percent interest in an Alaska 

regulated  gas  storage  utility  under  the  name  Cook  Inlet  Natural  Gas  Storage  Alaska  LLC  (CINGSA).  Petrogas  Energy 

Corporation (Petrogas) was also added as a subsidiary of AltaGas upon the close of the acquisition on December 15, 2020.

AltaGas, a Canadian corporation, is a leading North American energy infrastructure company that connects natural gas liquids 

(NGLs)  and  natural  gas  to  domestic  and  global  markets. The  Corporation’s  long-term  strategy  is  to  grow  in  attractive  areas 

across  its  Utilities  and  Midstream  business  segments  seeking  optimal  capital  deployment.  In  the  Midstream  business,  the 

Corporation  is  focused  on  optimizing  the  full  value  chain  of  energy  exports  by  providing  producers  with  solutions,  including 

global market access off the West Coast of North America via the Corporation’s footprint in the Montney region. In the Utilities 

business,  the  Corporation  seeks  to  grow  through  rate  base  investment  and  the  use  of  accelerated  rate  recovery  programs, 

while providing effective and cost-efficient service for customers. 

In 2020, AltaGas revised its reportable segments to align with the structure of its business following asset sales completed as 

part  of  its  2019  asset  monetization  program. As  a  result  of  these  changes, AltaGas  has  refocused  on  its  core  Utilities  and 

Midstream  segments.  Consistent  with  Management’s  strategic  view  of  the  business  and  the  basis  on  which  it  assesses 

performance and allocates resources, beginning in 2020, AltaGas has two operating segments: Utilities (which now includes 

the WGL retail marketing business) and Midstream. These operating segments have not been aggregated in the determination 

of AltaGas' reportable segments. All other assets are included in the Corporate/Other segment. AltaGas' operating segments 

include the following:  

§

Utilities,  which  serves  approximately  1.7  million  customers  with  a  rate  base  of  approximately  US$4.3  billion  through 

ownership  of  regulated  natural  gas  distribution  utilities  across  five  jurisdictions  in  the  United  States  and  two  regulated 

natural gas storage utilities in the United States, delivering affordable natural gas to homes and businesses. The Utilities 

business  also  includes  storage  facilities  and  contracts  for  interstate  natural  gas  transportation  and  storage  services,  as 

well as the affiliated retail energy marketing business, which serves approximately 0.5 million customers; and

§ Midstream,  which  includes  a  70  percent  interest  in  the  Ridley  Island  Propane  Export  Terminal  (RIPET)  and  an 

approximate 74 percent interest in the Ferndale terminal, allowing AltaGas to leverage its assets along the energy value 

chain in Western Canada and the Western United States including natural gas gathering and processing, NGL extraction 

and fractionation, and natural gas and NGL marketing. The Midstream segment also includes transmission, storage, and 

an interest in a regulated pipeline in the Marcellus/Utica gas formation in the northeastern United States. Upon close of 

the  acquisition  of  Petrogas,  the  Midstream  business  also  includes  a  74  percent  interest  in  Petrogas'  other  operations, 

which include LPG exports and distribution, domestic terminals, wellsite fluids and fuels, and trucking and liquids handling.

The Corporate/Other segment consists of AltaGas' corporate activities and a small portfolio of remaining power assets, certain 

of which are pending sale.  

2.   Summary of Significant Accounting Policies

BASIS OF PRESENTATION

These  Consolidated  Financial  Statements  have  been  prepared  by  Management  in  accordance  with  United  States  Generally 

Accepted Accounting Principles (U.S. GAAP). 

Pursuant  to  National  Instrument  52‑107,  "Acceptable  Accounting  Principles  and  Auditing  Standards"  (NI  52‑107),  financial 
statements  of  an  “SEC  issuer”  may  be  prepared  in  accordance  with  U.S.  GAAP.  On  January  21,  2020, AltaGas  filed  a  final 

short form base shelf prospectus in Alberta and a corresponding registration statement on Form F-10 in the United States, by 

virtue  of  which AltaGas  is  now  required  to  file  reports  under  section  15(d)  of  the Securities  Exchange  Act  of  1934  with  the 

United  States  Securities  and  Exchange  Commission. As  a  result, AltaGas  became  an  SEC  issuer  at  such  time  and  is  now 

entitled to prepare its financial statements in accordance with U.S. GAAP.

PRINCIPLES OF CONSOLIDATION

These Consolidated Financial Statements of AltaGas include the accounts of the Corporation, its subsidiaries, variable interest 

entities (VIEs) for which the Corporation is the primary beneficiary, and its interest in various partnerships and joint ventures 

where AltaGas has an undivided interest in the assets and liabilities. Investments in unconsolidated companies that AltaGas 

has significant influence, but not control, over are accounted for using the equity method.

Hypothetical  Liquidation  at  Book  Value  (HLBV)  methodology  is  used  for  certain  equity  method  investments  as  well  as 

consolidating  equity  investments  with  non-controlling  interests  when  the  governing  structuring  agreement  over  the  equity 

investment  results  in  different  liquidation  rights  and  priorities  than  what  is  reflected  by  the  underlying  ownership  interest 

percentage. The majority of AltaGas' HLBV investments were sold during 2019.

All  intercompany  balances  and  transactions  are  eliminated  on  consolidation.  Where  there  is  a  party  with  a  non‑controlling 
interest  in  a  subsidiary  that  AltaGas  controls,  that  non‑controlling  interest  is  reflected  as  “non‑controlling  interests”  in  the 
Consolidated Financial Statements. The non‑controlling interests in net income of consolidated subsidiaries are shown as an 
allocation of the consolidated net income and are presented separately in "net income applicable to non-controlling interests".

USE OF ESTIMATES AND MEASUREMENT UNCERTAINTY

The  preparation  of  Consolidated  Financial  Statements  in  accordance  with  U.S.  GAAP  requires  Management  to  make 

estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenue and 

expenses  during  the  period.  Key  areas  where  Management  has  made  complex  or  subjective  judgments,  when  matters  are 

inherently uncertain, include but are not limited to: determining the nature and timing of satisfaction of performance obligations 

and determining the transaction price and amounts allocated to performance obligations for revenue recognition; depreciation 

and amortization rates; determination as to whether a contract is or contains a lease; determination of the classification, term, 

and discount rate for leases; fair value of asset retirement obligations; fair value of property, plant and equipment and goodwill 

for  impairment  assessments;  fair  value  of  financial  instruments;  measurement  of  credit  losses;  provisions  for  income  taxes; 

assumptions used to measure employee future benefits; provisions for contingencies; purchase price allocations; and carrying 

value  of  regulatory  assets  and  liabilities.  Certain  estimates  are  necessary  for  the  regulatory  environment  in  which AltaGas' 

subsidiaries  or  affiliates  operate,  which  often  require  amounts  to  be  recorded  at  estimated  values  until  these  amounts  are 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 83

finalized  pursuant  to  regulatory  decisions  or  other  regulatory  proceedings.  By  their  nature,  these  estimates  are  subject  to 

measurement uncertainty and may impact the Consolidated Financial Statements of future periods.

SIGNIFICANT ACCOUNTING POLICIES

Rate-Regulated Operations 

SEMCO  Gas,  ENSTAR,  Washington  Gas,  and  Hampshire  Gas  (collectively  the  Utilities)  engage  in  the  delivery,  sale,  and 

storage  of  natural  gas.  SEMCO  Gas  and  ENSTAR  are  regulated  by  the  Michigan  Public  Service  Commission  (MPSC)  and 

Regulatory  Commission  of Alaska  (RCA),  respectively.  Washington  Gas  operates  in  the  District  of  Columbia,  Maryland,  and 

Virginia, and is regulated in those jurisdictions by the Public Service Commission of the District of Columbia (PSC of DC), the 

Maryland Public Service Commission (PSC of MD), and the Commonwealth of Virginia State Corporation Commission (SCC of 

VA), respectively. Hampshire is regulated under a cost-of-service tariff by the Federal Energy Regulatory Commission (FERC). 

The  MPSC,  RCA,  PSC  of  DC,  PSC  of  MD,  and  SCC  of  VA  exercise  statutory  authority  over  matters  such  as  tariffs,  rates, 

construction,  operations,  financing,  returns,  accounting,  and  certain  contracts  with  customers.  In  order  to  recognize  the 

economic  effects  of  the  actions  and  decisions  of  the  MPSC,  RCA,  PSC  of  DC,  PSC  of  MD,  and  SCC  of  VA,  the  timing  of 

recognition  of  certain  assets,  liabilities,  revenues,  and  expenses  as  a  result  of  regulation  may  differ  from  that  otherwise 

expected using U.S. GAAP for entities not subject to rate regulation. 

Regulatory assets represent future revenues associated with certain costs incurred in the current period or in prior periods that 

are expected to be recovered from customers in future periods through the rate setting process. Regulatory liabilities represent 

future reductions or limitations of increases in revenue associated with amounts that are expected to be refunded to customers 

through the rate setting process. 

Cash and Cash Equivalents 

Cash and cash equivalents consist of cash on hand, balances with banks, and investments in money market instruments with 

original maturities of less than three months. 

Restricted Cash Holdings from Customers 

Cash deposited, which is restricted and is not available for general use by AltaGas, is separately presented as restricted cash 

holdings in the Consolidated Balance Sheets. Pursuant to the acquisition of WGL Holdings, Inc. (the WGL Acquisition), rabbi 

trust funds were funded to satisfy certain Washington Gas executive and outside director retirement benefit plan obligations. 

The  rabbi  trust  funds  are  invested  in  money  market  funds  which  are  considered  cash  equivalents.  These  balances  are 

included  in  "prepaid  expenses  and  other  current  assets"  and  "long-term  investments  and  other  assets"  in  the  Consolidated 

Balance Sheets. Additionally, cash deposited in an escrow fund related to a cost sharing agreement with a third party has been 

recorded  as  restricted  cash  in  “accounts  receivable"  in  the  Consolidated  Balance  Sheets.  Please  refer  to  Note  29  for  more 

information.

Accounts Receivable 

Receivables are recorded net of the allowance for  doubtful  accounts in the Consolidated Balance Sheets. AltaGas  regularly 

analyzes  and  evaluates  the  collectability  of  the  accounts  receivable  based  on  a  combination  of  factors.  If  circumstances 

related  to  the  collectability  change,  the  allowance  for  doubtful  accounts  is  further  adjusted.  Accounts  are  written  off  when 

collection efforts are complete and future recovery is unlikely. 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 84

 
 
 
 
 
Inventory 

Inventory  consists  of  materials,  supplies,  natural  gas,  natural  gas  liquids,  crude  oil  and  condensates,  processed  finished 

products,  renewable  energy  credits,  and  emission  compliance  instruments  which  are  valued  at  the  lower  of  cost  or  net 

realizable  value.  Cost  of  inventory  is  assigned  using  a  weighted  average  cost  formula.  In  general,  commodity  costs  and 

variable  transportation  costs  are  capitalized  as  gas  in  underground  storage.  Fixed  costs,  primarily  pipeline  demand  charges 

and storage charges, are expensed as incurred through the cost of gas. 

Property, Plant, and Equipment (PP&E), Depreciation and Amortization 

Property, plant, and equipment are carried at cost. The Corporation depreciates the cost of capital assets, net of salvage value, 

on  a  straight-line  basis  over  the  estimated  useful  life  of  the  assets,  with  the  exception  of  rate-regulated  utilities  assets,  for 

which depreciation is calculated on a straight-line basis or over the contract term of a specific agreement at rates as approved 

by  the  regulatory  authorities,  and  a  small  number  of  assets  acquired  as  part  of  the  acquisition  of  Petrogas  for  which 

depreciation is calculated using the declining balance method. 

The Utilities charge maintenance and repairs directly to operating expense and capitalize betterments and renewal costs. In 

accordance  with  regulatory  requirements,  depreciation  expense  includes  an  amount  allowed  for  regulatory  purposes  to  be 

collected in current rates for future removal and site restoration costs. 

Interest costs are capitalized on major additions to property, plant, and equipment until the asset is ready for its intended use. 

The interest rate used for calculating the interest costs to be capitalized is based on AltaGas' prior quarter actual borrowing 

long-term interest rate. 

The Utilities capitalize an imputed carrying cost on assets during construction as authorized by regulatory authorities and the 

amount so capitalized is an allowance for funds used during construction (AFUDC). AFUDC is the amount that a rate-regulated 

enterprise  is  allowed  to  recover  for  its  cost  of  financing  assets  under  construction.  Capitalized  overhead,  administrative 

expenses, and AFUDC are included in the cost of the related assets and are recovered in rates charged to customers through 

depreciation expense, as allowed by the regulators. 

The range of useful lives for AltaGas’ PP&E is as follows: 

Utilities assets

Midstream assets

Corporate/Other assets

4 to 69 years

3 to 55 years

3 to 46 years

As required by the regulatory authority, net additions to SEMCO's utility assets are amortized for one half-year in the year in 

which they are brought into active service. Net additions to WGL’s assets are amortized in the month after they are brought 

into active service. 

Generally, when a regulated asset is retired or disposed of, there is no gain or loss recorded in the Consolidated Statements of 

Income. Any difference between the cost and accumulated depreciation of the asset, net of salvage proceeds, is charged to 

accumulated depreciation or another regulatory asset or liability account. It is expected that any gain or loss that is charged to 

accumulated depreciation or another regulatory account will be reflected in future depreciation expense when it is refunded or 

collected in rates. When a non-regulated asset is retired or disposed of from PP&E, the original cost and related accumulated 

depreciation and amortization are derecognized and any gain or loss is recorded in the Consolidated Statements of Income. 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 85

 
Intangible Assets 

Intangible assets are recorded at cost. Intangible assets which have a finite useful life are amortized on a straight-line basis 

over their term or estimated useful life. The range of useful lives for intangible assets with a finite life is as follows: 

Energy services relationships

Software

Land rights

5 years

3 to 20 years

5 to 43 years

Extraction and Transmission (E&T) Contracts

25 years

Commodity contracts

5 to 20 years

Assets Held for Sale 

The  Corporation  classifies  assets  as  held  for  sale  when  the  carrying  amount  will  be  principally  recovered  through  a  sale 

transaction  rather  than  through  continuing  use. This  condition  is  met  when  Management  approves  and  commits  to  a  formal 

plan  to  sell  the  assets,  the  assets  are  available  for  immediate  sale  in  their  present  condition,  and  Management  expects  the 

sale  to  close  within  the  next  12  months.  Upon  classifying  an  asset  as  held  for  sale,  an  asset  is  recorded  at  the  lower  of  its 

carrying value or the estimated fair value less cost to sell. Assets held for sale are not depreciated or amortized. 

Business Acquisitions 

Business acquisitions are accounted for using the acquisition method. Under the acquisition method, assets and liabilities of 

the  acquired  entity  are  recorded  at  fair  value  at  the  date  of  acquisition. Acquisition-related  costs  are  expensed  as  incurred. 

Goodwill represents the excess of purchase price over the fair value of the net assets acquired. Management applies its best 

estimates and assumptions to determine the fair value of net assets acquired; however, the estimates are subject to further 

refinement  of  assumptions  over  a  measurement  period,  which  may  be  up  to  one  year  from  the  acquisition  date.  During  the 

measurement period, adjustments to assets acquired and liabilities assumed may be recorded, with a corresponding impact to 

goodwill.

Provisions on Assets 

If  facts  and  circumstances  suggest  that  a  long-lived  asset  or  an  intangible  asset  may  be  impaired,  the  carrying  value  is 

reviewed. If this review indicates that the value of the asset is not recoverable, as determined by the projected undiscounted 

cash flows related to the asset over its remaining life, then the carrying value of the asset is reduced to its estimated fair value 

and an impairment loss is recognized. 

Goodwill is not subject to amortization, but assessed at least annually for impairment, or more often when events or changes 

in circumstances indicate that goodwill may be impaired. The annual assessment of goodwill is performed at the reporting unit 

level, which is an operating segment or one level below. The Corporation has the option to first assess qualitative factors to 

determine whether events or changes in circumstances indicate that the goodwill may be impaired. If a quantitative impairment 

test is performed, the fair value of the reporting unit will be compared to its carrying value (including goodwill). If the carrying 

value  of  the  reporting  unit  exceeds  the  fair  value,  goodwill  is  reduced  to  its  fair  value  and  an  impairment  loss  would  be 

recorded in the Consolidated Statements of Income. 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 86

 
 
Investments Accounted for by the Equity Method 

The equity method of accounting is used for investments in which AltaGas has the ability to exercise significant influence, but 

does not have a controlling interest. Equity investments are initially measured at cost and are adjusted for the Corporation’s 

proportionate  share  of  earnings  or  losses.  Equity  investments  are  increased  for  contributions  made  and  decreased  for 

distributions received. To the extent an investee undertakes activities necessary to commence its planned principal operations, 

the Corporation will capitalize interest costs associated with its investment during such period. 

The  HLBV  methodology  is  used  to  allocate  earnings  or  losses  for  certain  WGL  equity  method  investments  when  WGL’s 

ownership  interest  percentage  is  different  than  distribution  percentages.  When  applying  HLBV  accounting,  the  Corporation 

determines the amount that it would receive if an equity investment entity were to liquidate all of its assets at book value (as 

valued in accordance with U.S. GAAP) and distribute that cash to the investors based on the contractually defined liquidation 

priorities. The change in the Corporation’s claim on the equity investment entity's book value at the beginning and end of the 

reporting  period  (adjusted  for  contributions  and  distributions)  is  the  Corporation’s  share  of  the  earnings  or  losses  from  the 

equity investment for the period. 

An  equity  method  investment  is  reviewed  for  impairment  whenever  events  or  changes  in  circumstances  indicate  that  the 

carrying amount of the investment may not be recoverable. When such condition is deemed other than temporary, the carrying 

value of the investment is written down to its fair value, and an impairment charge is recorded in the Consolidated Statements 

of Income. 

Financial Instruments 

Non-Utility Operations 

All financial instruments are initially recorded at fair value unless they qualify for, and are designated under, a normal purchase 

and normal sale (NPNS) exemption. Subsequent measurement of the financial instruments is based on their classification. The 

financial  assets  are  classified  as  "held-for-trading",  "held-to-maturity",  or  "loans  and  receivables".  Financial  liabilities  are 

classified as "held-for-trading" or other financial liabilities. Subsequent measurement is determined by classification.

A physical contract generally qualifies for the NPNS exemption if the transaction is reasonable in relation to AltaGas’ business 

needs and AltaGas has the ability, and intent, to deliver or take delivery of the underlying item. AltaGas continually assesses 

the  contracts  designated  under  the  NPNS  exemption  and  will  discontinue  the  treatment  of  these  contracts  under  this 

exemption where the criteria are no longer met. 

Held-for-trading  instruments  include  non-derivative  financial  assets  and  financial  assets  and  liabilities  that  may  consist  of 

swaps,  options,  forwards,  and  equity  securities.  These  financial  instruments  are  initially  recorded  at  their  fair  value,  with 

subsequent changes in fair value recorded in net income. Held-to-maturity, loans and receivables, and other financial liabilities 

are recognized at amortized cost using the effective interest method unless they are held-for-sale and recognized at the lower 

of cost or fair value less transaction fees. 

Investments  in  equity  instruments  not  accounted  for  under  the  equity  method  that  do  not  have  a  quoted  market  price  in  an 

active  market  are  measured  at  cost.  Income  earned  from  these  investments  is  included  in  the  Consolidated  Statements  of 

Income under "other income". 

Derivatives  embedded  in  other  financial  instruments  or  contracts  (the  host  instrument)  are  recorded  separately  and  are 

measured  at  fair  value  if  the  economic  characteristics  of  the  embedded  derivative  are  not  closely  related  to  the  host 

instrument, the terms of the embedded derivative are the same as those of a standalone derivative, and the entire contract is 

not held-for-trading or accounted for at fair value. Changes in fair value are included in earnings. 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 87

The  fair  values  recorded  on  the  Consolidated  Balance  Sheets  reflect  netting  of  the  asset  and  liability  positions  where 

counterparty master netting arrangements contain provisions for net settlement. 

Transaction costs related to the acquisition of held-for-trading financial assets and liabilities are expensed as incurred. 

Transaction costs for obtaining debt financing other than line-of-credit arrangements are recognized as a direct deduction from 

the  related  debt  liability  on  the  Consolidated  Balance  Sheets.  Transaction  costs  related  to  line-of-credit  arrangements  are 

capitalized and included under "long-term investments and other assets" on the Consolidated Balance Sheets. Premiums and 

discounts  are  netted  against  long-term  debt  on  the  Consolidated  Balance  Sheets. The  deferred  charges  are  amortized  over 

the life of the related debt on an effective interest basis and included in “interest expense” on the Consolidated Statements of 

Income. 

Regulated Utility Operations 

All  physical  and  financial  derivative  contracts  are  initially  recorded  at  fair  value.  Changes  in  the  fair  value  of  derivative 

instruments  that  are  recoverable  or  refunded  to  customers  when  they  settle  are  recorded  as  regulatory  assets  or  liabilities. 

Changes in the fair value of derivatives not affected by rate regulation are reflected in net income. 

Transaction costs for obtaining debt financing and reacquired debt costs are recorded as regulatory assets or liabilities, or as a 

reduction of the debt liability on the Consolidated Balance Sheets. 

Weather-Related Instruments 

WGL purchases certain weather-related instruments, such as heating degree day (HDD) derivatives and cooling degree day 

(CDD)  derivatives  to  manage  weather  and  price  risks  related  to  its  natural  gas  and  electricity  sales.  These  derivatives  are 

accounted for in accordance with ASC 815-45, Derivatives and Hedging – Weather Derivatives. For HDD derivatives, gains or 

losses  are  recognized  when  the  actual  HDD’s  falls  above  or  below  the  contractual  HDD’s  for  each  instrument.  For  CDD 

derivatives,  gains  or  losses  are  recognized  when  the  average  temperature  exceeds  or  is  below  a  contractually  stated  level 

during the contract period. Refer to Note 23 for further discussion on weather-related instruments. 

Hedges 

As part of its risk management strategy, AltaGas may use derivatives to reduce its exposure to commodity price, interest rate, 

and foreign exchange risk. AltaGas may designate certain U.S. dollar-denominated debt as a net investment hedge of its U.S. 

subsidiaries. No other derivatives have been designated as hedges under ASC Topic 815. 

Non-Utility Operations

The change in fair value of cash flow hedges is recognized in OCI. Gains or losses from cash flow hedges are reclassified to 

net income when the hedged transaction affects earnings, such as when the hedged forecasted transaction occurs.

Regulated Utility Operations

During planned issuances of debt securities, Washington Gas may utilize derivative instruments to manage the risk of interest-

rate volatility. Gains and losses associated with these types of derivatives are recorded as regulatory liabilities or assets, and 

amortized in accordance with regulatory requirements, typically over the life of the related debt. 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 88

Credit Losses

The following are the Corporation's significant accounting policies upon adoption of ASC 326:

Accounts receivable, contract assets, a loan to an affiliate, and other long-term receivables within the scope of ASC 326 are 

recorded net of the allowance for credit losses in the Consolidated Balance Sheets. AltaGas regularly analyzes and evaluates 

the  collectability  of  the  accounts  receivable  based  on  a  combination  of  factors.  If  circumstances  related  to  the  collectability 

change, the  allowance for credit losses is adjusted. Accounts are written off when collection efforts are complete  and future 

recovery is unlikely. See below for a description of how expected credit loss estimates are developed.

Utilities Customer Receivables and Contract Assets  

AltaGas is exposed to risk through the non-payment of utility bills by customers. To manage this customer credit risk, AltaGas' 

regulated  utilities  customers  are  offered  budget  billing  options  or  high  risk  customers  may  be  required  to  provide  a  cash 

deposit until the requirement for deposit refunds are met. AltaGas can recover a portion of non-payments from customers in 

future periods through the rate-setting process. For accounts receivable generated by the Utilities business, an allowance for 

credit  losses  is  recorded  against  revenue  and  is  recognized  using  a  historical  loss-rate  based  on  historical  payment  and 

collection experience. This rate may be adjusted based on Management’s expectations of unusual macroeconomic conditions 

and other factors. AltaGas regularly evaluates the reasonableness of the allowance based on a combination of factors, such 

as:  the  length  of  time  receivables  are  past  due,  historical  expected  payment,  collection  experience,  financial  condition  of 

customers,  and  other  circumstances  that  could  impact  customers'  ability  or  desire  to  make  payments.  For  retail  energy 

marketing  customer  receivables  where  AltaGas  has  enrolled  in  a  regulatory  utility  purchase  of  receivable  program,  the 

associated utility discount rate is used to determine credit losses.

Midstream Customer Receivables and Contract Assets

AltaGas operates under an existing credit policy that is designed to mitigate credit risk. Credit limits are established for each 

counterparty and credit enhancements such as letters of credit, parent guarantees, and cash collateral may be required. The 

creditworthiness  of  all  counterparties  is  continuously  monitored.  A  credit  loss  reserve  is  recorded  for  receivables  with 

customers and trading counterparties AltaGas considers to be below investment grade by applying an estimated loss rate. The 

estimated loss rate is based on the historical default rates published by external rating agencies. For accounts receivable, a 

one-year rate is used. For contract assets, historical loss rates associated with the estimated time frame that the contract asset 

will  be  billed  to  the  customer  is  used.  In  the  event  a  customer  or  trading  counterparty  no  longer  exhibits  similar  risk 

characteristics, the associated receivable is evaluated individually. 

Other

For  other  long-term  receivables,  associated  counterparties  are  evaluated  and  assigned  internal  credit  ratings  based  on 

AltaGas' credit policy. An allowance for credit losses is recorded based on historical default rates published by external credit 

rating agencies and a rate commensurate with the period in which the receivables are expected to be collected.

Debt

AltaGas uses short-term debt in the form of commercial paper and advances under its syndicated bank credit facilities to fund 

seasonal cash requirements. Short-term obligations are excluded from current liabilities if AltaGas has the ability and the intent 

to refinance these obligations on a long-term basis. The ability to refinance is primarily demonstrated through the availability of 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 89

long-term  revolving  committed  credit  facilities  in  an  amount  equal  to  or  greater  than  the  expected  maximum  short-term 

obligation.

Asset Retirement Obligations 

AltaGas  recognizes  asset  retirement  obligations  in  the  period  in  which  the  legal  obligation  is  incurred  and  a  reasonable 

estimate of fair value can be determined. The associated asset retirement costs are capitalized as part of the carrying amount 

of the asset and are depreciated over the estimated useful life of the asset. The liability is increased due to the passage of time 

over  the  estimated  period  until  the  settlement  of  the  obligation,  with  a  corresponding  charge  to  accretion  expense  for  asset 

retirement obligations. 

There  are  timing  differences  between  accretion  and  depreciation  amounts  being  recorded  pursuant  to  GAAP  and  the 

recognition  of  depreciation  expense  for  legal  asset  removal  costs  that  are  recovered  in  rates,  as  allowed  by  the  regulators. 

These timing differences are recorded as a reduction to “regulatory liabilities” in accordance with ASC 980. 

Certain midstream and utility assets will have future legal obligations on retirement, but an asset retirement obligation has not 

been  recorded  due  to  its  indeterminate  life  and  corresponding  indeterminable  timing  and  scope  of  these  asset  retirement 

obligations. The Utilities recognize asset retirement obligations for some interim retirements, as expected by their regulators. 

Revenue Recognition 

AltaGas has revenue from various sources, including rate-regulated revenue, commodity sales, midstream service contracts, 

gas  sales  and  transportation  services,  and  storage  services.  For  a  detailed  description  of  the  Corporation’s  revenue 

recognition policy by major source of revenue, please refer to Note 24. 

Foreign Currency Translation 

Monetary assets and liabilities denominated in a foreign currency are converted to the functional currency using the exchange 

rate  in  effect  at  the  balance  sheet  date.  Adjustments  resulting  from  the  conversion  are  recorded  in  the  Consolidated 

Statements  of  Income.  Non-monetary  assets  and  liabilities  are  converted  at  the  historical  exchange  rate  in  effect  at  the 

transaction date. Revenues and expenses are converted at the exchange rate applicable at the transaction date. 

For  foreign  entities  with  a  functional  currency  other  than  Canadian  dollars, AltaGas’  reporting  currency,  assets  and  liabilities 

are  translated  into  Canadian  dollars  at  the  rate  in  effect  at  the  reporting  date.  Revenues  and  expenses  are  translated  at 

average exchange rates during the reporting period. All adjustments resulting from the translation of the foreign operations are 

recorded in OCI. 

AltaGas may designate some of its U.S. dollar denominated long-term debt as a foreign currency hedge of its investment in 

foreign  operations. Accordingly,  foreign  exchange  gains  and  losses,  from  the  dates  of  designation,  on  the  translation  of  the 

U.S. dollar denominated long-term debt are included in OCI. 

Share Options and Other Compensation Plans

Share options granted are recorded using fair value. Compensation expense is measured at the date of the grant using the 

Black-Scholes-Merton model and is recognized over the vesting period of the options. Consideration received by AltaGas on 

exercise of the share options is credited to shareholders’ equity.

AltaGas  has  a  phantom  unit  plan  (Phantom  Plan,  formerly  the  medium-term  incentive  plan)  for  employees  and  executive 

officers which includes two types of awards: restricted units (RUs) and performance units (PUs). A portion of AltaGas’ RUs and 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 90

 
PUs are valued based on the dividends declared during the vesting period and the weighted average share price of AltaGas' 

common shares multiplied by the units outstanding at the end of the vesting period. Upon vesting, the RUs and PUs are paid 

in cash. The other portion of RUs and PUs are valued at US$1 per unit. Upon vesting, the RUs and PUs are paid in cash. All 

PUs are also subject to a performance multiplier ranging from 0 to 2.4 dependent on the Corporation's performance relative to 

performance targets as approved by the Board of Directors. Compensation expense is recognized using the liability method 

and  is  recorded  as  operating  and  administrative  expense  over  the  vesting  period. A  change  in  value  of  the  RUs  or  PUs  is 

recognized in the period the change occurs. 

In addition, AltaGas has a deferred share unit plan (DSUP) for directors, officers, and employees as an additional form of long-

term variable compensation incentive. Although the DSUP is available to directors, officers, and employees, AltaGas currently 

only  grants  deferred  share  units  (DSUs)  under  the  DSUP  as  a  form  of  director  compensation.  The  DSUs  granted  are  fully 

vested upon being credited to a participant’s account, the participant is entitled to payment upon retirement, and payment is 

not subject to satisfaction of any requirements as to any minimum period of membership or employment or other conditions. 

DSUs are accounted for at fair value. Compensation expense is determined based on the fair value of the DSUs on the date of 

the grant and fluctuations in fair value are recognized in the period the change occurs. 

Pension Plans and Post-Retirement Benefits

AltaGas maintains defined benefit pension plans, defined contribution plans, and other post-retirement benefit plans for eligible 

employees. Contributions made by the Corporation to the defined contribution plans are expensed in the period in which the 

contribution occurs. 

The  cost  of  defined  benefit  pension  plans  and  post-retirement  benefits  is  actuarially  determined  using  the  projected  benefit 

method  prorated  based  on  service  and  Management’s  best  estimate  of  expected  plan  investment  performance,  salary 

escalation, retirement ages of employees, expected health care costs, and other actuarial factors including discount rates and 

mortality.  Pension  plan  assets  are  measured  at  fair  value.  The  expected  return  on  plan  assets  is  based  on  historical  and 

projected  rates  of  return  for  each  asset  class  in  the  plan  portfolio.  The  projected  benefit  obligation  is  discounted  using  the 

market interest rate on high-quality debt instruments with cash flows matching the timing and amount of benefit payments.

Unrecognized actuarial gains and losses in excess of 10 percent of the greater of the benefit obligation and the fair value of 

plan assets or the market-related value of assets along with any unamortized past service costs and credits are amortized on a 

straight-line  basis  over  the  expected  average  remaining  service  life  of  active  employees.  The  expected  average  remaining 

service period of the active members covered by the defined benefit pension plans and post-retirement benefit plans is 10.2 

years and 13.0 years, respectively.

AltaGas recognizes the overfunded or underfunded status of its pension and post-retirement benefit plans as either assets or 

liabilities in the Consolidated Balance Sheets. Unrecognized actuarial gains and losses and past service costs and credits that 

arise during the period are recognized in OCI or a regulatory asset or liability. 

For  certain  regulated  utilities,  the  Corporation  expects  to  recover  pension  expense  in  future  rates  and  therefore  records 

unrecognized balances as either regulatory assets or liabilities. The regulatory assets or liabilities are amortized on a straight-

line basis over the expected average remaining service life of active employees. 

In 2020, AltaGas made a voluntary change in accounting principle for calculating the market-related value of assets (MRVA) 

used in the determination of Washington Gas' net periodic pension and other post-retirement benefit plan costs. The change 

uses the fair value approach for the fixed income investment asset class of the plan assets, compared to the prior method that 

utilized  a  calculated  value  where  gains  and  losses  arising  from  changes  in  fair  value  were  deferred  and  amortized  into  the 

calculation of the MRVA over a period of five years. The MRVA is used in the calculation of the expected return on assets and 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 91

the  recognized  actuarial  gain  or  loss  components  of  net  periodic  benefit  cost. The  approach  applied  for  all  other  classes  of 

assets remains unchanged. 

Management  believes  that  using  the  fair  value  approach  for  the  fixed  income  investments  in  plan  assets  is  preferable  as  it 

more closely aligns the recognition of related components within the net periodic benefit cost. 

This change in accounting principle was not considered material to prior periods or the current year; therefore, the impact of 

the change was recognized in the current period. On the Consolidated Statements of Income, for the year ended December 

31, 2020, the change resulted in an increase to income before income taxes of approximately $25 million (recorded within the 

line item “other income”) and an increase to net income applicable to common shares of approximately $19 million ($0.07 per 

basic  and  diluted  common  share),  net  of  the  tax  impact  of  approximately  $6  million  recorded  within  the  line  item  "deferred 

income tax  expense (recovery)". Amounts related  to  regulated utility  operations  that  are  expected to be recoverable  from  or 

refunded to customers through the rate-setting process have been reflected as adjustments to regulatory assets or liabilities on 

the Consolidated Balance Sheets. For further discussion of pension plans and retiree benefits, see Note 28.

Income Taxes 

Income taxes for the Corporation and its subsidiaries are calculated using the liability method of accounting for income taxes. 

Under this method, deferred income tax assets and liabilities are determined based on differences between the carrying value 

and  the  tax  basis  of  assets  and  liabilities  and  are  measured  using  the  enacted  tax  rates  and  laws  that  are  in  effect  in  the 

periods in which the differences are expected to be settled or realized. Deferred income tax assets are routinely reviewed, and 

a valuation allowance is recorded to reduce the deferred tax assets if it is more likely than not that deferred tax assets will not 

be realized. 

The financial statement effects of an uncertain tax position are recognized when it is more likely than not, based on technical 

merits, that the position will be sustained upon examination by a taxing authority. The current and deferred tax impact is equal 

to the largest amount, considering possible settlement outcomes, that is greater than 50 percent likely of being realized upon 

settlement with the taxing authorities. 

Investment  tax  credits  are  recognized  as  reductions  to  income  tax  expense  over  the  estimated  service  lives  of  the  related 

properties. 

The  rate-regulated  natural  gas  distribution  subsidiaries  recognize  a  separate  regulatory  asset  or  liability  for  the  amount  of 

deferred income taxes expected to be recovered from, or paid to, customers in the future. 

Net Income per Share 

Basic net income per common share is computed using the weighted average number of common shares outstanding during 

the  period.  Dilutive  net  income  per  common  share  is  calculated  using  the  weighted  average  number  of  common  shares 

outstanding adjusted for dilutive common shares related to the Corporation’s share-based compensation awards. 

The potentially dilutive impact of the share-based compensation awards is determined using the treasury stock method. Under 

the treasury stock method, awards are treated as if they had been exercised with any proceeds used to repurchase common 

stock  at  the  average  market  price  during  the  period.  Any  incremental  difference  between  the  assumed  number  of  shares 

issued and purchased is included in the diluted share computation. 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 92

 
 
Contingencies 

Liabilities  for  loss  contingencies  arising  from  claims,  assessments,  litigation  and  other  sources  are  recorded  when  it  is 

probable  that  a  liability  has  been  incurred  and  the  amount  can  be  reasonably  estimated.  Any  such  accruals  are  adjusted 

thereafter as additional information becomes available or circumstances change.

Leases

The following are the Corporation’s significant accounting policies:

Leases – Lessee

AltaGas  determines  if  an  arrangement  is  a  lease  at  inception.  Operating  leases  are  included  in  right-of-use  (ROU)  assets, 

current operating lease liabilities, and long-term operating lease liabilities in the Consolidated Balance Sheets. Finance leases 

are included in property, plant and equipment and current and long-term debt in the Consolidated Balance Sheets.  

ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to 

make  lease  payments  arising  from  the  lease.  Operating  lease  ROU  assets  and  liabilities  are  recognized  at  commencement 

date  based  on  the  present  value  of  lease  payments  over  the  lease  term. AltaGas  uses  the  rate  implicit  in  the  lease  when 

readily determinable. When the implicit lease rate is not readily determinable, AltaGas uses its incremental borrowing rate to 

determine the present value of lease payments. AltaGas includes lessee options to renew or terminate the lease term in the 

determination  of  the  ROU  asset  and  lease  liability  when  exercise  is  reasonably  certain.  The  operating  lease  ROU  asset  is 

adjusted for lease payments made in advance of the commencement date, initial direct costs, and any lease incentives. 

Operating lease expense is recognized on a straight-line basis over the lease term in "operating and administrative expense". 

Depreciation and interest expense are recorded on finance leases.

Leases – Lessor

AltaGas determines if an arrangement is a lease at inception. Lease payments under an operating lease are recognized on a 

straight-line  basis  over  the  term  of  the  lease.  Variable  lease  payments  are  recognized  as  revenue  as  the  facts  and 

circumstances on which the variable lease payment is based occur.  

AltaGas does not include taxes assessed by governmental authorities, such as sales and related taxes, in the lease payments 

or variable lease payments.

Collaborative Arrangements

WGL  has  collaborative  arrangements  with  a  third  party  to  facilitate  the  asset  optimization  program.  The  collaborative 

arrangements allocate a tiered or fixed percentage of profits or losses to the third party as compensation for its participation. 

The  expense  recorded  related  to  the  collaborative  arrangements  totaled $21  million  for  the  year  ended  December  31,  2020 

(2019 - income of $1 million). 

ADOPTION OF NEW ACCOUNTING STANDARDS 

Effective  January  1,  2020, AltaGas  adopted  the  following  Financial Accounting  Standards  Board  (FASB)  issued Accounting 

Standards Updates (ASU): 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 93

 
 
 
 
 
 
 
 
 
 
§

In  June  2016,  FASB  issued  ASU  No.  2016-13  “Financial  Instruments  –  Credit  Losses  and  all  related  amendments 

(collectively "ASC 326"): Measurement of Credit Losses on Financial Instruments”. The ASU replaces the current “incurred 

loss” impairment methodology with an “expected loss” model for financial assets measured at amortized cost. AltaGas has 

applied ASC 326 using the modified retrospective approach through a cumulative-effect adjustment to retained earnings 

as of the effective date of the new standard. Prior periods presented for comparative purposes were not adjusted. Upon 

adoption of ASC 326, "accounts receivable, net of allowances" decreased by $2 million and "long-term investments and 

other assets" decreased by $5 million, with an offsetting increase to "accumulated deficit". AltaGas has elected to account 

for its cash equivalents at fair value. Please also refer to Note 23 of the Consolidated Financial statements as at and for 

the year ended December 31, 2020 for further details;

§

ASU No. 2018-13 “Fair Value Measurement – Disclosure Framework: Changes to the Disclosure Requirements for Fair 

Value Measurement”. The amendments in this ASU modify the disclosure requirements on fair value measurements. The 

adoption of this ASU did not have a material impact on AltaGas’ consolidated financial statements, but resulted in certain 

minor adjustments to the fair value disclosures. Please also refer to Note 23 of the Consolidated Financial statements as 

at and for the year ended December 31, 2020 for further details;

§

ASU No. 2018-17 “Consolidation: Targeted Improvements to Related Party Guidance for Variable Interest Entities”. The 

amendments in this ASU provide a private-company scope exception to the VIE guidance for certain entities and clarify 

that  indirect  interests  held  through  related  parties  under  common  control  are  considered  on  a  proportional  basis  when 

determining whether fees paid to decision makers and service providers are variable interests. The adoption of this ASU 

did not have a material impact on AltaGas’ consolidated financial statements;

§

ASU  No.  2018-18  "Collaborative  Arrangements:  Clarifying  the  Interaction  between  Topic  808  and  Topic  606".  The 

amendments  in  this  ASU  clarifies  that  certain  transactions  between  collaborative  arrangement  participants  should  be 

accounted for as revenue under ASC 606, adds unit-of-account guidance in ASC 808 to align with the guidance in ASC 

606, and requires that a transaction with a collaborative arrangement participant that is not directly related to sales to third 

parties, is precluded from presenting the transaction together with revenue recognized under ASC 606 if the collaborative 

arrangement  participant  is  not  a  customer.  The  adoption  of  this  ASU  did  not  have  a  material  impact  on  AltaGas’ 

consolidated financial statements; 

§

ASU No. 2019-01 "Leases: Codification Improvements". The amendments in this ASU provide a fair value exception for 

lessors that are not manufacturers or dealers, clarifies the presentation of principal payments received under sales-type 

and  direct  finance  leases  for  depository  and  lending  institutions,  and  clarifies  that  interim  transition  disclosure 

requirements related to the change on income statement, net income and related per share amounts for the adoption of 

ASC  842  are  not  required.  The  adoption  of  this ASU  did  not  have  a  material  impact  on AltaGas’  consolidated  financial 

statements;

§

ASU No. 2019-04 “Financial Instruments: Codification Improvements". The amendments in this ASU provide clarification 

and  improve  the  codification  in  recently  issued  accounting  standards  relating  to  credit  losses,  hedge  accounting,  and 

financial instruments. The amendments related to credit losses were evaluated in conjunction with ASU 2016-13 above. 

The adoption of this ASU did not have a material impact on AltaGas’ consolidated financial statements; and

§

ASU No. 2020-03 "Codification Improvements to Financial Instruments". The amendments in this ASU provide clarification 

and improve the codification to certain aspects of accounting standards related to financial instruments. The adoption of 

this ASU did not have a material impact on AltaGas’ consolidated financial statements. 

Effective December 31, 2020, AltaGas adopted the following FASB issued ASU:

AltaGas Ltd. – 2020 MD&A and Financial Statements - 94

§	 ASU  No.  2018-14  “Compensation-Retirement  Benefits-Defined  Benefit  Plans  –  General:  Disclosure  Framework  – 

Changes  to  the  Disclosure  Requirements  for  the  Defined  Benefit  Plans”.  The  amendments  in  this  ASU  modify  the 

disclosure  requirements  on  defined  benefit  pension  and  other  post-retirement  plans.  The  adoption  of  this ASU  did  not 

have  a  material  impact  on  AltaGas'  consolidated  financial  statements,  but  resulted  in  certain  modifications  to  the 

disclosures in the pension footnote. Please also refer to Note 28 of the Consolidated Financial statements as at and for 

the year ended December 31, 2020 for further details.

FUTURE CHANGES IN ACCOUNTING PRINCIPLES 

In  December  2019,  FASB  issued  ASU  No.  2019-12  "Income  Taxes:  Simplifying  the  Accounting  for  Income  Taxes".  The 

amendments  in  this  ASU  simplify  the  accounting  for  income  taxes  by  clarifying  certain  aspects  of  current  guidance  and 

removing  some  exceptions  to  the  general  principles  in ASC  740. The  amendments  in  this ASU  are  effective  for  fiscal  years 

beginning after December 15, 2020, and interim periods within those fiscal years. The adoption of this ASU is not expected to 

have a material impact on AltaGas’ financial statements. 

In  January  2020,  FASB  issued ASU  No.  2020-01  "Derivatives  and  Hedging:  Clarifying  the  Interactions  between  Topic  321, 

Topic  323,  and  Topic  815".  The  amendments  in  this  ASU  clarify  the  application  of  the  measurement  alternative  for  equity 

instruments  and  the  measurement  of  non-derivative  forward  contracts  or  purchased  call  options  used  to  acquire  equity 

securities. The amendments in this ASU are effective for fiscal years beginning after December 15, 2020, and interim periods 

within those fiscal years. Early adoption is permitted. The adoption of this ASU is not expected to have a material impact on 

AltaGas’ financial statements. 

In March 2020, FASB issued ASU No. 2020-04 "Reference Rate Reform: Facilitation of the Effects of Reference Rate Reform 

on  Financial  Reporting."  The  amendments  in  this  ASU  provide  optional  expedients  and  exceptions  for  applying  GAAP  to 

contract modifications and hedging relationships affected by reference rate reform if certain criteria are met. These apply only 

to contracts, hedging relationships, and other transactions that reference London Interbank Offered Rate (LIBOR) or another 

reference rate expected to be discontinued because of reference rate reform. The amendments in this ASU are effective as of 

March 12, 2020 through December 31, 2022. AltaGas may elect to apply the amendments as of any date from the beginning of 

an interim period that includes or is subsequent to March 12, 2020 on a prospective basis. AltaGas has not elected to adopt 

this ASU as of December 31, 2020, and is assessing the impact of this ASU on its consolidated financial statements. 

In August 2020, FASB issued ASU No. 2020-06 "Debt with Conversion and Other Options and Topic 815-40 - Derivatives and 

Hedging - Contracts in Entity's Own Equity: Accounting for Convertible Instruments and Contract in an Entity's Own Equity." 

The amendments in this Update simplify the accounting for certain financial instruments with characteristics of liabilities and 

equity, including convertible instruments and contracts in an entity’s own equity. The amendments in this Update are effective 

for  public  business  entities  that  meet  the  definition  of  a  Securities  and  Exchange  Commission  (SEC)  filer,  excluding  entities 

eligible  to  be  smaller  reporting  companies  as  defined  by  the  SEC,  for  fiscal  years  beginning  after  December  15,  2021, 

including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning 

after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted. The adoption of this 

ASU is not expected to have a material impact on AltaGas' financial statements. 

3.   Acquisition of Petrogas Energy Corporation 

On December 15, 2020, following the receipt of all required approvals, AltaGas acquired an additional 37 percent of Petrogas 

Energy Corp. (the Petrogas Acquisition) for total cash consideration upon close of approximately $715 million. Additional post-

acquisition  contingent  payments  of  up  to  $16  million  may  be  paid  no  later  than  2022  based  on  certain  criteria,  including 

earnings targets being met (Note 29). AltaGas funded the transaction through draws on its existing credit facilities. As a result 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 95

of the transaction, AltaGas' ownership in Petrogas has increased to approximately 74 percent with Idemitsu Kosan Co., Ltd. 

(Idemitsu) owning the remaining approximately 26 percent. Subsequent to the transaction, AltaGas controls Petrogas and as 

such, Petrogas results have been consolidated for the period subsequent to close.

This  acquisition  is  consistent  with  AltaGas'  global  export  strategy,  growing  Midstream  operations,  and  corporate  focus  on 

building a diversified, low-risk, high-growth Utilities and Midstream business. The transaction provides AltaGas with operational 

responsibility  of  strategic  assets  that,  along  with  the  Ridley  Island  Propane  Export  Terminal  and  existing  Midstream  assets, 

position the Company to capture efficiencies that are expected to accrue to shareholders and customers.

AltaGas accounted for the acquisition as a business combination achieved in stages and re-measured it's previously held 37 

percent equity investment in Petrogas at an acquisition date fair value of $631 million, resulting in a gain of $22 million. The fair 

value of assets and liabilities acquired were determined using a combination of income and cost approach. The fair value of 

the previously held interest and non-controlling interests were derived from the valuation of the assets and liabilities including 

considerations  for  expected  synergies.  Prior  to  the  acquisition,  AltaGas'  indirect  non-controlling  interest  in  Petrogas  was 

accounted for as an investment accounted for by the equity method (Note 14).

The  following  table  summarizes  the  preliminary  purchase  price  allocation  representing  the  consideration  paid  and  the 

estimated  fair  value  of  the  net  assets  acquired  as  at  December  15,  2020.  The  purchase  price  allocation  is  preliminary  and 

reflects  Management’s  current  best  estimate  of  the  fair  value  of  Petrogas'  assets  and  liabilities  based  on  the  analysis  of 

information obtained to date. Management is continuing to obtain specific information to support the valuation of property, plant 

and equipment, intangibles, investments accounted for by the equity method, non-controlling interest, contingencies, income 

taxes,  environmental  matters  and  asset  retirement  obligations.  As  additional  information  becomes  available,  the  purchase 

price allocation may differ materially from the preliminary purchase price allocation below. The offset to any adjustments made 

to the aforementioned financial statement captions during the measurement period are expected to be recorded in goodwill. 

Any adjustments to the purchase price allocation will be made as soon as practicable but no later than one year from the date 

of acquisition.

The fair value of AIJVLP's non-controlling interest in Petrogas at the acquisition date was $467 million, which was determined 

in  the  same  manner  described  for  the  previously  held  investments.  Included  in  the  fair  value  calculation  are  synergies  that 

AltaGas expects to achieve as part of the acquisition. The synergies are broken down into items that will accrue to Petrogas 

versus other AltaGas businesses. AltaGas operates businesses that are similar in nature to Petrogas and expects some of the 

synergies  to  impact  assets  such  as  RIPET  and  other  processing  facilities.  The  allocation  of  synergies  to  the  various 

businesses is currently based on the expectations that existed as of the acquisition date. Further refinement of the synergies 

will  occur  as  the  businesses  are  integrated  and  assessed  by  AltaGas’  management.  New  allocations  of  synergies  will  be 

carefully assessed to determine their impact on the purchase price allocation.   

The fair value of property, plant and equipment was estimated using the valuation methodologies described in ASC 820, Fair 

Value  Measurements  and  Disclosures,  to  value  the  property,  plant  and  equipment  purchased.  The  preliminary  fair  value  of 

Petrogas' property, plant and equipment was determined using both the income and cost approaches.

The  acquired  intangible  assets  consist  primarily  of  the  fair  value  of  contractual  arrangements  for  the  purchase  and  sale  of 

commodities. These intangibles have been valued using the income approach. 

Investments accounted for by the equity method include Petrogas' 50 percent equity interest in Petrogas Terminals Penn LLC, 

and 40 percent equity interest in Strathcona Storage LP. The preliminary fair value of these investments was determined using 

an income approach.

The fair value of current assets and current liabilities approximate their carrying values due to their short-term nature, with the 

exception  of  inventory.  Inventory  of  $164  million  has  been  recorded  at  it's  fair  value  using  the  expected  selling  prices  and 

reasonable adjustments for the current location of the products. A contingent liability related to a property tax dispute has been 

recorded as part of the purchase price allocation. This preliminary amount represents management’s best estimate of the fair 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 97

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
value  of  the  contingent  liability  and  has  been  included  in  current  liabilities. This  item  is  included  in  the  preliminary  purchase 

price allocation as the hearings on the matter will occur over the next 12 months and the outcome will be settled.

Right of use assets and lease liabilities have been recorded for operating leases. The right of use assets have been adjusted 

to reflect the market lease rates at the acquisition date and resulted in a reduction of the acquired right of use assets. 

Deferred  income  tax  assets  and  liabilities  have  been  applied  on  the  cumulative  amount  of  tax  applicable  to  temporary 

differences between the accounting and tax values of assets and liabilities and are considered preliminary.

The preliminary purchase price allocation includes goodwill of approximately $1.2 billion. The goodwill is primarily related to the

opportunities  to  grow  the  LPG  export  business,  expanded  access  to  capital  and  greater  financial  flexibility  as  a  result  of 

increased scale, and earnings diversification. The goodwill recognized as part of this transaction is not deductible for income 

tax purposes, and as such, no deferred taxes have been recorded related to this goodwill.

Pre-tax acquisition expenses for the year ended December 31, 2020 of approximately $6 million were incurred and included in 

the Consolidated Statements of Income.

Upon  completion  of  the  Petrogas  Acquisition,  AltaGas  began  consolidating  Petrogas.  For  the  period  from  close  of  the 

transaction through December 31, 2020, Petrogas has generated approximately $143 million in revenues and $3 million in net 

income after taxes. 

The following supplemental unaudited, pro forma consolidated financial information for the years ended December 31, 2020 

and  2019  gives  effect  to  the  Petrogas  Acquisition  as  if  it  had  closed  on  January  1,  2019.  This  pro  forma  information  is 

presented for information purposes only and does not purport to be indicative of the results that would have occurred had the 

Petrogas Acquisition  taken  place  at  the  beginning  of  2019,  nor  is  it  indicative  of  the  results  that  may  be  expected  in  future 

periods.

Pro forma net income after taxes excludes all non-recurring acquisition-related expenses incurred by AltaGas and Petrogas. 

Pro forma net income after taxes was also adjusted to exclude AltaGas' equity earnings from Petrogas prior to the acquisition, 

finance costs associated with credit facilities used to fund the Petrogas Acquisition, as well as the associated tax impacts. For 

the year ended December 31, 2020, the total after-tax pro forma adjustments decreased net income after taxes by $31 million 

(2019 – $75 million).

4.   Dispositions

AltaGas Canada Inc. (ACI)

On March 31, 2020, the Public Sector Pension Investment Board and the Alberta Teachers' Retirement Fund Board acquired 

all  the  issued  and  outstanding  common  shares  of ACI  for  $33.50  per  share. AltaGas  owned  11,025,000  (approximately  37 

percent) of ACI's common shares and received cash proceeds of approximately $369 million upon close. For the year ended 

December  31,  2020,  AltaGas  recognized  a  pre-tax  gain  on  disposition  of  approximately  $206  million  in  the  Consolidated 

Statements of Income under the line item "other income". Following a name change in connection with the arrangement, ACI 

changed its name to TriSummit Utilities Inc.

AltaGas Ltd. – 2020 MD&A and Financial Statements - 98

Distributed Generation Assets

In  2019,  AltaGas  closed  the  disposition  of  its  portfolio  of  U.S.  distributed  generation  assets.  The  majority  of  assets  were 

transferred in 2019, except for one project for which ownership will not legally transfer to the purchaser until various consents 

and approvals are obtained. As such, the carrying value of the assets and liabilities relating to this project remain classified as 

held for sale on the Consolidated Balance Sheets as at December 31, 2020 (Note 5). For the year ended December 31, 2020, 

AltaGas recognized a pre-tax gain on disposition of approximately $9 million in the Consolidated Statements of Income under 

the  line  item  "other  income"  related  to  projects  transferred  in  2020.  In  addition, AltaGas  recorded  a  pre-tax  provision  of $3 

million related to the remaining U.S. distributed generation project which has not yet transferred to the purchaser (Note 6). The 

purchaser  was  entitled  to  after-tax  earnings  from  the  distributed  generation  projects,  including  the  project  awaiting  consent, 

beginning September 1, 2019. 

Harmattan Land Parcels

In the second quarter of 2020, AltaGas completed the sale of land parcels located near the Harmattan gas processing plant for 

gross cash proceeds of approximately $3 million. There was no gain or loss resulting from this disposition.

Pomona Energy Storage Facility and Ripon Gas-fired Facility

In the third quarter of 2020, AltaGas completed the sales of AltaGas Pomona Energy Storage Inc. and land related to a gas-

fired power generation facility in the U.S., as well as a gas fired facility in Ripon, California, for aggregate gross cash proceeds, 

before  working  capital  and  other  adjustments,  of  approximately  $67  million.  AltaGas  recognized  a  pre-tax  gain  on  these 

dispositions of approximately $8 million in the Consolidated Statements of Income under the line item "other income".

In 2019, AltaGas announced that it entered into a definitive agreement for the sale of its portfolio of U.S. distributed generation 

assets (Note 4). The transaction closed in September 2019; however, there is one project for which ownership will not legally 

transfer  to  the  purchaser  until  various  consents  and  approvals  are  obtained. As  such,  the  carrying  value  of  the  assets  and 

liabilities related to this project remains classified as held for sale at December 31, 2020, which resulted in the reclassification 

of $4 million of assets to assets held for sale and $1 million of liabilities to liabilities associated with assets held for sale on the 

Consolidated  Balance  Sheets.  The  portion  of  the  purchase  price  relating  to  this  project  is  approximately  $4  million  (US$3 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 99

 
 
 
 
 
million) and is recorded within "accounts payable and accrued liabilities" on the Consolidated Balance Sheets until this project 

is legally transferred to the purchaser. These assets and liabilities are recorded in the Corporate/Other segment.

In 2020, AltaGas recorded pre-tax provisions of $106 million. Of this, approximately $104 million related to the Alton Natural 

Gas  Storage  Project,  which  was  impaired  as  AltaGas  does  not  believe  that  the  future  expected  cash  generation  from  the 

project aligns with the current carrying value. The remaining $2 million pre-tax provision related to land parcels located near 

the  Harmattan  gas  processing  plant  which  were  sold  in  the  second  quarter  of  2020  (Note  4).  The  pre-tax  provisions  were 

recorded against property, plant and equipment. In 2019, AltaGas recorded pre-tax provisions of $34 million related to a sour 

gas treatment facility in Alberta.

Corporate/Other 

In 2020, AltaGas recorded pre-tax provisions totaling $3 million related to the remaining U.S. distributed generation projects 

which  have  not  yet  transferred  to  the  purchaser  and  are  classified  as  held  for  sale  as  at  December  31,  2020.  The  pre-tax 

provisions were recorded against property, plant and equipment. In 2019, AltaGas recorded pre-tax provisions of $382 million 

related to various assets in the Corporate/Other segment.

Certain of AltaGas’ revenues are obtained through power purchase agreements or take-or-pay contracts whereby AltaGas is 

the lessor in these operating lease arrangements. Minimum lease payments received are amortized over the term of the lease. 

Contingent rentals are recorded when the condition that created the present obligation to make such payments occurs such as 

when actual electricity is generated and delivered.

13.   Variable Interest Entities 

Consolidated VIEs

AltaGas consolidates VIEs where the Corporation is deemed the primary beneficiary. The primary beneficiary of a VIE has the 

power to direct the activities of the entity that most significantly impact its economic performance such as being the provider of 

construction, operating and marketing services to the entity. In addition, the primary beneficiary of a VIE also has the obligation 

to absorb losses of the entity or the right to receive benefits that could potentially be significant to the VIE. AltaGas determined 

that it is the primary beneficiary of the following VIEs:

Ridley Island LPG Export Limited Partnership 

On  May  5,  2017,  AltaGas  LPG  Limited  Partnership  (AltaGas  LPG),  a  wholly-owned  subsidiary  of  AltaGas,  and  Vopak 

Development  Canada  Inc.  (Vopak),  a  wholly-owned  subsidiary  of  Koninklijke  Vopak  N.V.  (Royal  Vopak),  a  public  company 

incorporated  under  the  laws  of  the  Netherlands,  formed  the  Ridley  Island  LPG  Export  Limited  Partnership  (RILE  LP)  to 

develop, own and operate the Ridley Island Propane Export Terminal (RIPET). AltaGas’ subsidiaries hold a 70 percent interest 

while Vopak holds a 30 percent interest in RILE LP. The construction cost of RIPET was funded by AltaGas LPG and Vopak in 

proportion to their respective interests in RILE LP. As part of the arrangements, AltaGas entered into a long-term agreement for 

the capacity of RIPET with RILE LP, and AltaGas and certain of its subsidiaries provide operating services to RILE LP. 

AltaGas  has  determined  that  RILE  LP  is  a  VIE  in  which  it  holds  variable  interests  and  is  the  primary  beneficiary.  In  the 

determination that AltaGas is the primary beneficiary of the VIE, AltaGas noted that it has the power to direct the activities that 

most significantly impact the VIE’s economic performance through the operating and marketing services provided to RILE LP. 

In  addition,  AltaGas  has  the  obligation  to  absorb  the  losses  and  the  right  to  receive  the  benefits  that  could  potentially  be 

significant to RILE LP through the long-term agreement for the capacity of RIPET. As such, AltaGas has consolidated RILE LP.

The assets of RILE LP are the property of RILE LP and are not available to AltaGas for any other purpose. RILE LP’s asset 

balances can only be used to settle its own obligations. The liabilities of RILE LP do not represent additional claims against 

AltaGas’ general assets. AltaGas’ exposure to loss as a result of its interest as a limited partner is its net investment. AltaGas 

and Royal Vopak have provided limited guarantees for the obligations of their respective subsidiaries for the construction cost 

of  RIPET.  With  the  commencement  of  commercial  operations  at  RIPET,  the  terms  of  the  long-term  capacity  agreement 

between AltaGas LPG and RILE LP provide for a return on and of capital and reimbursement of RIPET's operating costs by 

AltaGas LPG in accordance with the terms set out in the agreement.

Upon the acquisition of Petrogas on December 15, 2020, AltaGas acquired an indirect interest in SSLP, a partnership formed 

with ATCO Energy Solutions Ltd. to construct, operate, and maintain underground NGL storage caverns at Fort Saskatchewan, 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 105

 
 
 
 
 
 
  
Alberta. The facility currently has four underground NGL storage salt caverns in service, with a fifth cavern under development. 

As at December 31, 2020, AltaGas held an indirect 30 percent equity investment in SSLP with a carrying value of $124 million, 

inclusive  of  fair  value  adjustments  on  acquisition  date  (Note  3).  SSLP  is  not  consolidated  by  Petrogas  and  instead  is 

accounted for by the equity method of accounting. Petrogas is not the primary beneficiary of SSLP and it does not have the 

power to direct the activities most significant to the economic performance of SSLP.

(a)  ACI was acquired by the Public Sector Pension Investment Board and the Alberta Teachers' Retirement Fund Board on March 31, 2020 (Note 4).

(b)  Upon acquisition of Petrogas on December 15, 2020 (Note 3), AltaGas no longer has an equity investment in AIJVLP.

(c)  The  equity  method  is  considered  appropriate  because  Constitution  is  a  Limited  Liability  Company  (LLC)  with  specific  ownership  accounts  and  ownership 

between five and fifty percent, resulting in WGL Midstream exercising a more than minor influence over the investee's operating and financing policies. In 

February 2020, the partners of Constitution elected not to proceed with the pipeline project and Constitution was dissolved. The loss recorded in 2020 relates 

to a provision recorded against the equity investment (see below for further discussion).

(d)  Disposed of in 2019.

(e)  The  equity  method  is  considered  appropriate  because  Mountain  Valley  is  an  LLC  with  specific  ownership  accounts  and  ownership  between  five  and  fifty 

percent, resulting in WGL Midstream exercising a more than minor influence over the investee's operating and financing policies.

(f) 

Petrogas'  preferred  shares  ceased  to  be  an  investment  accounted  for  by  the  equity  method  after AltaGas  acquired  a  controlling  interest  in  Petrogas  on 

December 15, 2020 (Note 3).

(g)  Acquired on December 15, 2020 as part of the Petrogas Acquisition (Note 3).

The carrying amount of certain equity investments differs from the amount of the underlying equity in net assets. These basis 

differences  include  amounts  related  to  purchase  accounting  adjustments,  capitalized  interest,  and  a  contractual  cap  on 

contributions to Mountain Valley.

Equity Method Investments Acquired

In connection with the acquisition of Petrogas (Note 3), AltaGas acquired the following investments accounted for by the equity 

method:

Petrogas Terminals Penn LLC 

Petrogas  owns  a  50  percent  equity  interest  in  Petrogas Terminals  Penn  LLC,  a  partnership  with  a  regional  propane  retailer 

engaged in rail offloading of propane for distribution by truck to customers in Pennsylvania and other nearby states. 

Strathcona Storage LP 

Petrogas  owns  a  40  percent  equity  interest  in  Strathcona  Storage  Limited  Partnership,  a  partnership  with  ATCO  Energy 

Solutions  Ltd.,  which  is  engaged  in  the  development  of  underground  NGL  storage  caverns  at  Fort  Saskatchewan, Alberta. 

SSLP is considered a VIE (Note 13) and is accounted for using the equity method.

AltaGas Canada Inc.

On March 31, 2020, the Public Sector Pension Investment Board and the Alberta Teachers' Retirement Fund Board acquired 

all  the  issued  and  outstanding  common  shares  of  ACI  for  $33.50  per  share  (Note  4).  AltaGas  owned  11,025,000 

(approximately 37  percent)  of ACI's  common  shares  and  received  cash  proceeds  of  approximately $369  million  upon  close. 

AltaGas  recognized  a  pre-tax  gain  on  disposition  of  approximately  $206  million  in  the  Consolidated  Statements  of  Income 

under the line item "other income" (Note 27). Following a name change in connection with the arrangement, ACI changed its 

name to TriSummit Utilities Inc.

Petrogas/AIJVLP

At the beginning of 2020, AltaGas held an indirect approximate one-third interest in Petrogas through its equity investment in 

AIJVLP.  In  the  first  quarter  of  2020,  one  of  Petrogas'  shareholders  has  converted  their  preferred  shares  of  Petrogas  to 

common shares resulting in the dilution of AltaGas' indirect ownership in Petrogas common shares from approximately 33.3 

percent to approximately 29.2 percent. In addition, prior to the close of the Petrogas Acquisition in the fourth quarter of 2020, 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 107

 
AltaGas converted their preferred shares of Petrogas to common shares. As a result of these transactions, in 2020, AltaGas 

recognized pre-tax dilution losses totaling approximately $30 million in the Consolidated Statements of Income under the line 

item  "income  from  equity  investments".  There  were  additional  expenses  of  $12  million  recorded  to  "income  from  equity 

investments" related to various adjustments to pre-acquisition balances of Petrogas. This primarily included amounts relating 

to  severance,  transaction  costs  and  impairment  losses  related  to  the  acquisition  of  Petrogas.  Upon  close  of  the  Petrogas 

Acquisition on December 15, 2020, AltaGas recognized a pre-tax gain of $22 million in the Consolidated Statements of Income 

under the line item "other income" on the re-measurement of it's previously held equity investment in AIJVLP. Subsequent to 

the acquisition, AltaGas no longer has an equity investment in AIJVLP.

Provisions on investments accounted for by the equity method

In the year ended December 31, 2020, AltaGas recorded a pre-tax provision on equity investments of approximately $7 million 

in  the  Consolidated  Statements  of  Income  under  the  line  item  "income  from  equity  investments"  for  costs  associated  with 

AltaGas' equity investment in the Constitution pipeline project which was canceled in February 2020. 

In the year ended December 31, 2019, AltaGas recorded a pre-tax provision of $44 million against its investment in Meade as 

a result of the sale of WGL Midstream's interest in the Central Penn Pipeline. The disposition of the investment in this entity 

was  completed  in  the  fourth  quarter  of  2019.  In  addition,  AltaGas  recorded  a  pre-tax  provision  of  $2  million  against  its 

investment in Craven County Wood Energy LP as a result of a pending sale. The disposition of the investment in this entity 

was completed in the third quarter of 2019.

(a)  Certain amounts relating to Utility asset retirement obligations are recorded through regulatory assets or liabilities on the Consolidated Balance Sheets due to 

regulatory treatment. The remaining portion is recorded through the Consolidated Statements of Income. 

The  majority  of  the  asset  retirement  obligations  are  associated  with  distribution  and  transmission  systems  in  the  Utilities 

segment. 

AltaGas estimates the undiscounted cash required to settle the asset retirement obligations, excluding growth for inflation, at 

December 31, 2020 was $816 million (December 31, 2019 - $727 million). 

The asset retirement obligations have been recorded in the Consolidated Financial Statements at estimated values discounted 

at  rates  between  2.0  and  8.5  percent  (December  31,  2019  -  between  2.0  to  8.5  percent)  and  are  expected  to  be  incurred 

between 2021 and 2138 (December 31, 2019 - between 2020 and 2137). No assets have been legally restricted for settlement 

of the estimated liability. 

18.   Environmental Matters 

AltaGas is subject to federal, provincial, state and local laws and regulations related to environmental matters. These laws and 

regulations may require expenditures over a long time frame to control environmental effects. Almost all of the environmental 

liabilities  AltaGas  has  recorded  are  for  costs  expected  to  be  incurred  to  remediate  sites  where  AltaGas  or  a  predecessor 

affiliate  operated  manufactured  gas  plants  (MGPs).  Estimates  of  liabilities  for  environmental  response  costs  are  difficult  to 

determine with precision because of the various factors that can affect their ultimate level. These factors include, but are not 

limited to, the following:

▪

▪

▪

▪

▪

▪

the complexity of the site;

changes in environmental laws and regulations at the federal, state, and local levels;

the number of regulatory agencies or other parties involved;

new  technology  that  renders  previous  technology  obsolete  or  experience  with  existing  technology  that  proves 

ineffective;

the level of remediation required; and

variations between the estimated and actual period of time that must be dedicated to respond to an environmentally-

contaminated site.

AltaGas Ltd. – 2020 MD&A and Financial Statements - 112

 
 
 
 
 
 
 
 
AltaGas  has  identified  up  to  twelve  sites  where  it  or  its  predecessors  may  have  operated  MGPs.  In  connection  with  these 

operations, AltaGas is aware that coal tar and certain other by-products of the gas manufacturing process are present at or 

near some former sites and may be present at others.

As at December 31, 2020, a liability of $13 million has been recorded on an undiscounted basis related to future environmental 

response costs (December 31, 2019 - $14 million) in the Consolidated Balance Sheets under the line items “accounts payable 

and  accrued  liabilities  and  other  long-term  liabilities”.  These  estimates  principally  include  the  minimum  liabilities  associated 

with  a  range  of  environmental  response  costs  expected  to  be  incurred.  As  at  December  31,  2020,  AltaGas  estimated  the 

maximum  liability  associated  with  all  of  its  sites  to  be  approximately  $39  million  (December  31,  2019  -  $40  million).  The 

estimates  were  determined  by AltaGas’  environmental  experts,  based  on  experience  in  remediating  MGP  sites  and  advice 

from  legal  counsel  and  environmental  consultants.  The  variation  between  the  recorded  and  estimated  maximum  liability 

primarily  results  from  differences  in  the  number  of  years  that  will  be  required  to  perform  environmental  response  processes 

and the extent of remediation that may be required. 

As at December 31, 2020, AltaGas reported a regulatory asset of $15 million (December 31, 2019 - $18 million) for the portion 

of environmental response costs that are expected to be recoverable in future rates (Note 21).

The  amount  shown  on  the  Consolidated  Balance  Sheets  as  deferred  income  tax  liabilities  represents  the  net  differences 

between the tax basis and book carrying values on the Corporation's balance sheets at enacted tax rates.

The Alberta government passed the Job Creation Tax Cut in 2019 which reduced Alberta's corporate tax rate from 12 percent 

to 11 percent on July 1, 2019. The tax rate was further reduced from 11 percent to 8 percent on July 1, 2020. 

As  at  December  31,  2020,  the  Corporation  had  tax-effected  non-capital  losses  of  approximately  $293  million,  which  will  be 

available to offset future taxable income. If not used, these losses will expire between 2023 and 2040.

Uncertain Tax Positions

The Corporation recognizes the benefit of an uncertain tax position only when it is more likely than not that such a position will 

be  sustained  by  the  taxing  authorities  based  on  the  technical  merits  of  the  position. The  current  and  deferred  tax  impact  is 

equal  to  the  largest  amount,  considering  possible  settlement  outcomes,  that  has  greater  than  50  percent  likelihood  of  being 

realized upon settlement with the taxing authorities.

On an annual basis, the Corporation and its subsidiaries file tax returns in Canada and various foreign jurisdictions. In Canada, 

AltaGas' federal and provincial tax returns for the years 2013 to 2019 remain subject to examination by taxation authorities. In 

the  United  States,  both  the  federal  and  state  tax  returns  for  the  years  2016  to  2019  remain  subject  to  examination  by  the 

taxation authorities. 

Management determined that the following provision was required for uncertainty on income taxes during the year:

AltaGas  accounts  for  certain  transactions  in  accordance  with  ASC  980,  Regulated  Operations.  AltaGas  refers  to  this 

accounting  guidance  for  regulated  entities  as  “regulatory  accounting”.  Under  regulatory  accounting,  utilities  are  permitted  to 

defer  expenses  and  income  as  regulatory  assets  and  liabilities,  respectively,  in  the  Consolidated  Balance  Sheets  when  it  is 

probable  that  those  expenses  and  income  will  be  allowed  in  the  rate-setting  process  in  a  period  different  from  the  period  in 

which  they  would  have  been  reflected  in  the  Consolidated  Statements  of  Income  by  a  non-rate-regulated  entity.  These 

deferred  regulatory  assets  and  liabilities  are  included  in  the Consolidated  Statements  of  Income  in  future  periods  when  the 

amounts are reflected in customer rates. If an application is filed to modify customer rates with certain regulatory commissions, 

AltaGas  is  permitted  to  charge  customers  new  rates,  subject  to  refund,  until  the  regulatory  commission  renders  a  final 

decision.  During  this  interim  period,  a  provision  is  recorded  for  a  rate  refund  regulatory  liability  based  on  the  difference 

between the amount collected in rates and the amount expected to be recovered from a final regulatory decision. 

Management’s assessment of the probability of recovery or pass-through of regulatory assets and liabilities requires judgment 

and interpretation of laws and regulatory agency orders, rules, and rate-making conventions. The relevant regulatory bodies 

are the MPSC, RCA, PSC of DC, PSC of MD, and SCC of VA.

If,  for  any  reason,  the  Corporation  ceases  to  meet  the  criteria  for  application  of  regulatory  accounting  for  all  or  part  of  its 

operations, the regulatory assets and liabilities related to those portions ceasing to meet such criteria would be de-recognized 

from  the  Consolidated  Balance  Sheets  and  included  in  the  Consolidated  Statements  of  Income  for  the  period  in  which  the 

discontinuance of regulatory accounting occurs. Criteria that give rise to the discontinuance of regulatory accounting include: 

(i) increasing competition that restricts the ability of the Corporation to charge prices sufficient to recover specific costs, and (ii) 

a significant change in the manner in which rates are set by regulatory agencies from cost-based regulation to another form of 

regulation. The Corporation’s review of these criteria currently supports the continued application of regulatory accounting for 

all its utilities. 

The following table summarizes the regulatory assets and liabilities recorded in the Consolidated Balance Sheets, as well as 

the remaining period, as at December 31, 2020 and 2019, over which the Corporation expects to realize or settle the assets or 

liabilities:

(a)  Washington Gas is not entitled to a rate of return on these assets. Washington Gas is allowed to recover and required to pay, using short-term interest rates, 

the carrying costs related to billed gas costs due from and to its customers in the District of Columbia and Virginia jurisdictions.

(b)  Represents amounts for deferred over or under collections of surcharges associated with Washington Gas' accelerated pipeline recovery programs in the 

District of Columbia, Maryland, and Virginia.

(c) 

Includes deferred gas costs and fair value of derivatives, which are not included in customer bills until settled. 

(d)  Represents  the  timing  difference  between  the  recognition  of  workers  compensation  and  short-term  disability  costs  in  accordance  with  generally  accepted 

accounting principles and the way these costs are recovered through rates. Certain utilities have recovered pension costs related to regulated operations in 

rates, and as such, the Corporation has recorded a regulatory asset for the unamortized costs associated with the defined benefit and post-retirement benefit 

plans. Depending on the method utilized by the utility, the recovery period can be either the expected service life of the employees, the benefit period for 

employees, or a specific recovery period as approved by the respective regulator.

(e)  This balance represents allowed environmental remediation expenditures at SEMCO and Washington Gas sites to be recovered through rates.

(f) 

The  losses  or  gains  on  the  issuance  and  extinguishment  of  debt  and  interest-rate  derivative  instruments  include  unamortized  balances  from  transactions 

executed  in  prior  years.  These  transactions  create  gains  and  losses  that  are  amortized  over  the  remaining  life  of  the  debt  as  prescribed  by  regulatory 

accounting requirements. As at December 31, 2020, this also includes a fair value adjustment of $76 million (December 31, 2019 - $80 million) recorded on 

the WGL Acquisition in 2018.

(g)  This balance represents amounts due from customers for deferred tax assets and liabilities related to tax benefits/expenses on deductions flowed directly to 

customers prior to the adoption of income tax normalizations for ratemaking purposes and to tax rate changes.

(h)  Represents  amounts  for  deferred  credits  associated  with  Washington  Gas'  participation  in  the  energy  conservation  and  efficiency  program  EmPower  in 

Maryland. 

(i)  Regulatory assets established to capture and track incremental COVID-19 related costs.

(j)  On September 18, 2013, CINGSA received a US$15 million gas storage facility tax credit from the State of Alaska for the benefit of its firm storage service 

customers. CINGSA will derive no direct or indirect benefit from the tax credit. Following receipt of the tax credit, CINGSA deposited it in a separate interest-

bearing  account.  CINGSA  will  act  as  a  custodian  of  the  tax  credit  and  any  interest  earned  for  the  benefit  of  CINGSA's  customers.  On  an  annual  basis, 

covering the years 2012 through 2021, CINGSA will disburse to the customers 1/10th of the amount of the tax credit not subject to refund to the State and 

interest earned. The RCA has approved the disbursement methodology.

(k)  The Tax Cuts and Jobs Act (TCJA) was enacted on December 22, 2017, and required the Corporation to revalue its U.S. deferred tax assets and liabilities in 

2018 to the lower federal corporate tax rate of 21 percent, resulting in excess accumulated deferred income taxes. The tax rate reduction created a reduction 

in deferred tax liability, which SEMCO Gas and Washington Gas are required to refund to ratepayers.

(l)  Represents estimated refunds related to customers billed at a higher rate during the interim period as part of the 2019 Virginia rate case.

(m)  The Virginia Coronavirus Relief Fund was received by WGL to provide direct assistance to Virginia customers with balances over 30 days in arrears.

(n)  This amount and timing of draw down is dependent upon the cost of removal of underlying utility property, plant and equipment and the life of property, plant 

and equipment.

23.   Financial Instruments and Financial Risk Management

The  Corporation’s  financial  instruments  consist  of  cash  and  cash  equivalents,  accounts  receivable,  risk  management 

contracts,  certain  long-term  investments  and  other  assets,  accounts  payable  and  accrued  liabilities,  dividends  payable, 

short-term and long-term debt and certain other current and long-term liabilities.  

Fair Value Hierarchy

AltaGas  categorizes  its  financial  assets  and  financial  liabilities  into  one  of  three  levels  based  on  fair  value  measurements 

and inputs used to determine the fair value. 

Level 1 - fair values are based on unadjusted quoted prices in active markets for identical assets or liabilities. Fair values are 

based on direct observations of transactions involving the same assets or liabilities and no assumptions are used. Included 

in this category are publicly traded shares valued at the closing price as at the balance sheet date.

Level  2  -  fair  values  are  determined  based  on  valuation  models  and  techniques  where  inputs  other  than  quoted  prices 

included  within  Level  1  are  observable  for  the  asset  or  liability  either  directly  or  indirectly. AltaGas  enters  into  derivative 

instruments  in  the  futures,  over-the-counter  and  retail  markets  to  manage  fluctuations  in  commodity  prices  and  foreign 

exchange rates. The fair values of power, natural gas, NGL, LPG, ocean freight, and oil derivative contracts were calculated 

using forward prices based on published sources for the relevant period, adjusted for factors specific to the asset or liability, 

including  basis  and  location  differentials,  discount  rates,  and  currency  exchange.  The  fair  value  of  foreign  exchange 

derivative  contracts  was  calculated  using  quoted  market  rates.  The  fair  value  of  foreign  exchange  option  contracts  were 

calculated using a variation of the Black-Scholes pricing model. 

Level 3 - fair values are based on inputs for the asset or liability that are not based on observable market data. AltaGas uses 

valuation techniques when observable market data is not available. Level 3 derivatives include physical contracts at illiquid 

market locations with no observable market data, long-dated positions where observable pricing is not available over the life 

of  the  contract,  contracts  valued  using  historical  spot  price  volatility  assumptions,  and  valuations  using  indicative  broker 

quotes for inactive market locations. A significant change to any one of these inputs in isolation could result in a significant 

upward or downward fluctuation in the fair value measurement. 

The  following  methods  and  assumptions  were  used  to  estimate  the  fair  value  of  each  significant  class  of  financial 

instruments:

Other current liabilities - the carrying amounts approximate fair value because of the short maturity of these instruments.

Current  portion  of  long-term  debt,  Long-term  debt  and  Other  long-term  liabilities  -  the  fair  value  of  these  liabilities  was 

estimated based on discounted future interest and principal payments using the current market interest rates of instruments 

with similar terms. 

Risk  management  assets  and  liabilities  -  the  fair  values  of  power,  natural  gas  and  NGL,  LPG,  ocean  freight,  and  oil 

derivative contracts were calculated using forward prices from published sources for the relevant period. The fair value of 

foreign  exchange  derivative  contracts  was  calculated  using  quoted  market  rates.  The  fair  value  of  Level  3  derivative 

contracts was calculated using internally developed valuation inputs and pricing models. 

Equity securities – the fair value of equity securities was calculated using quoted market prices.

AltaGas Ltd. – 2020 MD&A and Financial Statements - 118

Loans  and  receivables  –  the  fair  value  of  these  assets  was  estimated  based  on  discounted  future  interest  and  principal 

payments using the current market interest rates of instruments with similar terms.

(a)  To manage price risk associated with acquiring natural gas supply for Maryland, Virginia, and District of Columbia utility customers, Washington Gas, a 

subsidiary  of  the  Corporation,  enters  into  physical  and  financial  derivative  transactions.  Any  gains  and  losses  associated  with  these  derivatives  are 

recorded as regulatory liabilities or assets, respectively, to reflect the rate treatment for these economic hedging activities. Additionally, as part of its asset 

optimization program, Washington Gas enters into derivatives with the primary objective of securing operating margins that Washington Gas will ultimately 

realize. Regulatory sharing mechanisms provide for the annual realized profit from these transactions to be shared between Washington Gas' shareholder 

and customers; therefore, changes in fair value are recorded through earnings, or as regulatory assets or liabilities to the extent that it is probable that 

realized gains and losses associated with these derivative transactions will be included in the rates charged to customers when they are realized.

(b)  Excludes non-financial liabilities.

(a)

To manage price risk associated with acquiring natural gas supply for Maryland, Virginia, and District of Columbia utility customers, Washington Gas, a 

subsidiary  of  the  Corporation,  enters  into  physical  and  financial  derivative  transactions.  Any  gains  and  losses  associated  with  these  derivatives  are 

recorded as regulatory liabilities or assets, respectively, to reflect the rate treatment for these economic hedging activities. Additionally, as part of its asset 

optimization program, Washington Gas enters into derivatives with the primary objective of securing operating margins that Washington Gas will ultimately 

realize. Regulatory sharing mechanisms provide for the annual realized profit from these transactions to be shared between Washington Gas' shareholder 

and customers; therefore, changes in fair value are recorded through earnings, or as regulatory assets or liabilities to the extent that it is probable that 

realized gains and losses associated with these derivative transactions will be included in the rates charged to customers when they are realized.

(c)

Included under the line item "long-term investments and other assets" on the Consolidated Balance Sheets.
Excludes non‑financial liabilities.

Financial  assets  and  liabilities  not  included  in  the  fair  value  hierarchy  table  include  money  market  funds,  short  term  debt, 

commercial paper, and a long-term receivable (Note 12). The carrying value of these financial instruments approximate their 

fair value, which reflects the short-term maturity and/or normal credit terms of these financial instruments. 

The  following  table  includes  quantitative  information  about  the  significant  unobservable  inputs  used  in  the  fair  value

the fair value hierarchy are presented at the fair value as of the beginning of the period. Transfers out of Level 3 during the 

year ended December 31, 2020 were due to an increase in valuations using observable market inputs. Transfers into Level

Offsetting of Derivative Assets and Derivative Liabilities 

Certain of AltaGas’ risk management contracts are subject to master netting arrangements that create a legally enforceable 

right  for  a  counterparty  to  offset  the  related  financial  assets  and  financial  liabilities.  As  part  of  these  master  netting 

agreements, cash, letters of credit and parental guarantees may be required to be posted or obtained from counterparties in 

order to mitigate credit risk related to both derivative and non-derivative positions. Collateral balances are also offset against 

the  related  counterparties’  derivative  positions  to  the  extent  the  application  would  not  result  in  the  over-collateralization  of 

those derivative positions on the balance sheet.

Certain derivative instruments contain contract provisions that require collateral to be posted if the credit rating of AltaGas or 

certain of its subsidiaries falls below certain levels. At December 31, 2020, AltaGas has posted $nil (December 31, 2019 - 

$6 million) of collateral related to its derivative liabilities that contained credit-related contingent features. The following table

AltaGas  is  exposed  to  various  financial  risks  in  the  normal  course  of  operations  such  as  market  risks  resulting  from 

fluctuations in commodity prices, currency exchange rates and interest rates as well as credit risk and liquidity risk. 

Commodity Price Risk 

AltaGas  enters  into  financial  derivative  contracts  to  manage  exposure  to  fluctuations  in  commodity  prices.  The  use  of 

derivative instruments is governed under formal risk management policies and is subject to parameters set out by AltaGas’ 

Risk Management Committee and Board of Directors. AltaGas does not make use of derivative instruments for speculative 

purposes.

Natural Gas

In the normal course of business, AltaGas purchases and sells natural gas to support its infrastructure business. The fixed 

price  and  market  price  contracts  for  both  the  purchase  and  sale  of  natural  gas  extend  to  2040.  In  addition, AltaGas  may 

enter into financial derivative contracts as part of WGL’s asset optimization program. WGL optimized the value of its long-

term natural gas transportation and storage capacity resources during periods when these resources are not being used to 

physically serve utility customers.

AltaGas  had  the  following  forward  contracts  and  commodity  swaps  outstanding  related  to  the  activities  in  the  energy

Power 

AltaGas  sells  power  to  the Alberta  Electric  System  Operator  at  market  prices. AltaGas  also  sells  power  through  its  WGL 

Energy  Services  affiliate,  to  commercial,  industrial  and  mass  market  users  within  the  PJM  Regional  Transmission 

Organization  at  fixed  and  market  prices.  AltaGas'  strategy  is  to  mitigate  the  cash  flow  risk  to  power  prices  to  provide 

predictable  earnings.  Therefore, AltaGas  uses  third-party  swaps  and  purchase  contracts  to  fix  the  prices  over  time  on  a 

portion  of  the  volumes  to  mitigate  financial  exposure  associated  with  the  sale  contracts. These  power  purchase  and  sale 

contracts extend to 2025. As at December 31, 2020, AltaGas had no intention to terminate any contracts prior to maturity. 

AltaGas had the following power commodity forward contracts and commodity swaps outstanding as at December 31, 2020

AltaGas is exposed to foreign exchange risk as changes in foreign exchange rates may affect the fair value or future cash 

flows of the Corporation’s financial instruments. AltaGas has foreign operations whereby the functional currency is the U.S. 

dollar. As  a  result,  the  Corporation’s  earnings,  cash  flows,  and  OCI  are  exposed  to  fluctuations  resulting  from  changes  in 

foreign  exchange  rates. This  risk  is  partially  mitigated  to  the  extent  that AltaGas  has  U.S.  dollar-denominated  debt  and/or 

preferred  shares  outstanding.  AltaGas  may  also  enter  into  foreign  exchange  forward  derivatives  to  manage  the  risk  of 

fluctuating cash flows due to variations in foreign exchange rates.

AltaGas Ltd. – 2020 MD&A and Financial Statements - 125

 
 
 
AltaGas  may  designate  its  U.S.  dollar-denominated  debt  as  a  net  investment  hedge  of  its  U.S.  subsidiaries.  As  at 

December  31,  2020, AltaGas  has  not  designated  any  outstanding  debt  as  a  net  investment  hedge  (December  31,  2019  - 

US$300 million). For the year ended December 31, 2020, AltaGas incurred an after-tax unrealized loss of $9 million arising 
from the translation of debt in OCI (2019 ‑ after-tax unrealized gains of $60 million).

In  connection  with  the  Petrogas  Acquisition,  AltaGas  acquired  various  commodity  and  financial  derivative  instruments, 

including the following foreign exchange forward contracts which are outstanding as at December 31, 2020:

For the year ended December 31, 2020, AltaGas recorded an after-tax realized gain of $1 million on all foreign exchange 

forward contracts.

Interest Rate Risk

AltaGas is exposed to interest rate risk as changes in interest rates may impact future cash flows and the fair value of its 

financial instruments. The Corporation manages its interest rate risk by holding a mix of both fixed and floating interest rate 

debt. As at December 31, 2020, approximately 83 percent of AltaGas’ total outstanding short-term and long-term debt was at 

fixed  rates  (December  31,  2019  -  76  percent).  In  addition,  from  time  to  time, AltaGas  may  enter  into  interest  rate  swap 

agreements to fix the interest rate on a portion of its banker’s acceptances issued under its credit facilities. There were no 

outstanding interest rate swaps as at December 31, 2020.

Credit Risk 

Credit risk results from the possibility that a counterparty to a financial instrument fails to fulfill its obligations in accordance 

with the terms of the contract. 

AltaGas' credit policy details the parameters used to grant, measure, monitor and report on credit provided to counterparties. 

AltaGas minimizes counterparty risk by conducting credit reviews on counterparties in order to establish specific credit limits, 

both  prior  to  providing  products  or  services  and  on  a  recurring  basis.  In  addition,  most  contracts  include  credit  mitigation 

clauses that allow AltaGas to obtain financial or performance assurances from counterparties under certain circumstances. 

AltaGas maintains an allowance for doubtful accounts in the normal course of its business. 

AltaGas' maximum credit exposure consists primarily of the carrying value of the non-derivative financial assets and the fair 

value  of  derivative  financial  assets. As  at  December  31,  2020, AltaGas  had  no  concentration  of  credit  risk  with  a  single 

counterparty. 

Weather Related Instruments

WGL Energy Services utilizes heating degree day (HDD) instruments from time to time to manage weather and price risks 

related to its natural gas and electricity sales during the winter heating season. WGL Energy Services also utilizes cooling 

degree day (CDD) instruments and other instruments to manage weather and price risks related to its electricity sales during 

the  summer  cooling  season.  These  instruments  cover  a  portion  of  estimated  revenue  or  energy-related  cost  exposure  to 

variations in HDDs or CDDs. For the year ended December 31, 2020, a pre-tax loss of $3 million was recorded related to 

these instruments (2019 - pre-tax loss of $2 million).

(a)

An allowance for credit loss is assessed quarterly and is recorded based on historical default rates published by external credit rating agencies and a rate  

associated with the estimated time frame that the contract asset will be billed to the customer.

(b)

Includes loan to affiliate, which is no longer outstanding at December 31, 2020, and other long-term receivables (Notes 12 and 29). An allowance for credit 

loss is assessed quarterly and is recorded based on historical default rates published by external credit rating agencies and a rate commensurate with the 

period in which the receivable is expected to be collected.

(c)

Based  on  previous  collection  experience,  AltaGas  did  not  record  an  allowance  for  credit  losses  for  its  contract  assets  associated  with  its  energy 

management services projects with the U.S. federal government.

(d)

Includes $8 million recorded to a regulatory asset relating to the impact of COVID-19 on uncollectible accounts. 

Liquidity Risk 

Liquidity risk is the risk that AltaGas will not be able to meet its financial obligations as they come due. AltaGas manages this 

risk through its extensive budgeting and monitoring process to ensure it has sufficient cash and credit facilities to meet its 

obligations. AltaGas' objective is to maintain its investment-grade ratings to ensure it has access to debt and equity funding 

as required.

(b)  A  large  portion  of  revenue  generated  from  the  Utilities  segment  is  subject  to  rate  regulation  and  accordingly  there  are  circumstances  where  the  revenue 

recognized is mandated by the applicable regulators in accordance with ASC 980. 

(c)  Revenue  generated  from  certain  of AltaGas’  gas  facilities  is  accounted  for  as  operating  leases.  For  the  Corporate/Other  segment,  a  significant  amount  of 

revenue earned is through power purchase agreements which are accounted for as operating leases.

(d)  Risk management activities involve the use of derivative instruments such as physical and financial swaps, forward contracts, and options. These derivatives 

are accounted for under ASC 815 and ASC 825. A portion of revenue generated by the Utilities segment is from the physical sale and delivery of natural gas 

and power to end users.

(e)  Trading margins in the Midstream segment are reported in risk management and trading activities. AltaGas enters into derivative contracts for the purpose of 

optimizing its storage and transportation capacity as well as managing the transportation and storage assets on behalf of third parties. The trading margins, 

including unrealized gains and losses on derivative instruments, are netted within revenues. Gross revenues for the year ended December 31, 2020 of $437 

million associated with the GAIL Global (USA) LNG LLC (GAIL) contract and an Asset Management Agreement (AMA), which are in scope of ASC 606, are 

reported within risk management and trading activities. Revenue from the GAIL contract is recognized at a point in time based on the actual volumes of the 

commodity sold at the delivery point, which corresponds to the customer’s monthly invoice amount. The GAIL contract has a term of 20 years and began on 

March 31, 2018. Revenue from the AMA is recognized based on the amount WGL Midstream has the right to invoice the customer in accordance with ASC 

606. WGL executed the AMA in April 2020.

Revenue Recognition

The following is a description of the Corporation’s revenue recognition policy by segment and by major source of revenue from 

contracts with customers.

Utilities Segment

Gas Sales and Transportation Services

Customers are billed monthly based on regular meter readings. Customer billings are based on two main components: (i) a 

fixed service fee and (ii) a variable fee based on usage. Revenue is recognized over time when the gas has been delivered or 

as the service has been performed. As meter readings are performed on a cycle basis, AltaGas recognizes accrued revenue 

for  any  services  rendered  to  its  customers  but  not  billed  at  month-end.  The  vast  majority  of  these  contracts  are  “at-will”  as 

customers may cancel their service at any time, however, there are certain contracts that have terms of one year or longer. For 

these  long-term  contracts,  there  is  generally  a  contract  demand  specified  in  the  contract  whereby  the  customer  has  to  pay 

regardless  of  whether  or  not  gas  has  been  delivered.  These  contracts  generally  do  not  contain  any  make  up  rights  and 

revenue is recognized on a monthly basis as service has been performed. 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 131

 
 
 
 
 
 
 
Gas Storage Services

Gas  storage  customers  are  billed  monthly  for  services  provided.  Customer  billings  are  based  on  four  components:  (i) 

reservation charges; (ii) capacity charges; (iii) injection/withdrawal charges; and (iv) excess charges. Reservation charges are 

based on  the customer’s contract withdrawal quantity,  capacity charges are based on the customer’s total contract  quantity, 

and  injection/withdrawal  charges  are  based  on  the  volume  of  gas  delivered  to  or  from  the  customer.  Excess  charges  are 

applied to each day that the storage quantity exceeds 100 percent of the customer’s maximum storage quantity. Revenue is 

recognized as the service has been performed over time on a monthly basis, which corresponds to the invoice amount. The 

majority of these contracts have terms extending beyond one year. 

Commodity Sales

Commodity  sales  also  include  gas  sales  to  residential,  commercial,  and  industrial  customers  in  certain  jurisdictions  where 

WGL Energy Services is authorized as a competitive service provider. These commodity sales contracts have varying terms 

that  generally  range  from  one  to  five  years.  Customers  are  billed  monthly  based  on  the  amount  of  gas  delivered  to  the 

customer. Revenue is recognized based on the amount the Corporation is entitled to invoice the customer.  

Midstream Segment

Commodity Sales 

A portion of the NGL production from AltaGas’ extraction facilities is subject to frac spread between NGLs extracted and the 

natural gas purchased to make up the heating value of the NGLs extracted. For commodity sales contracts that do not meet 

the definition of a derivative or for contracts whereby AltaGas has elected to apply the normal purchase normal sales scope 

exception, the sales contract is accounted for under ASC 606. These commodity sales contracts have varying terms but the 

majority of the contracts have a one-year term which coincides with the NGL year. AltaGas recognizes revenue for commodity 

sales contracts at a point in time based on the actual volumes of the commodity sold at the delivery point, which corresponds 

to the customer’s monthly invoice amount.

Commodity sales contracts at RIPET and Ferndale generate revenue from the sale and delivery of LPGs to customers in Asia 

shipped  from  offshore  export  terminals.  Revenue  is  recognized  when  LPGs  are  loaded  onto  transport  vessels,  which  is  the 

delivery point. AltaGas has the right to consideration in an amount that directly corresponds to the volumes of LPGs loaded on 

a  vessel.  Petrogas'  commodity  sales  also  include  the  sale  of  upgraded  crude  oil,  processed  finished  products,  and  various 

fuels.  Delivery  takes  place  when  there  is  a  sales  contract  in  place,  specifying  delivery  volumes  and  sales  prices.  The 

consideration received under these contracts is variable based on commodity prices. 

Midstream Service Contracts

AltaGas  earns  revenue  from  its  field  gathering  and  processing  facilities,  extraction  facilities,  storage  facilities,  truck  hauling 

services,  rail  and  truck  loading  and  unloading  terminalling,  and  transmission  systems  through  a  variety  of  contractual 

arrangements. For arrangements that do not contain a lease, the revenue is accounted for under ASC 606 as follows:

Fee-for-service – The customer is charged a fee for the service provided on a per unit volume basis. Contract terms generally 

range from one month to up to the life of the reserves. Revenue under this type of arrangement is recognized over time as the 

service is provided, which corresponds to the customer’s monthly invoice amount.

Take-or-pay – The customer has agreed to a minimum volume commitment whereby the customer must have AltaGas process 

or deliver a specified volume at a rate per unit that is specified in the contract. Quantities that the customer is unable to deliver 

are considered deficiency quantities. Certain of AltaGas’ take-or-pay contracts contain provisions whereby the customer can 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 132

make up deficiency quantities in subsequent periods. Under this type of arrangement, any consideration received relating to 

the  deficiency  quantities  that  will  be  made  up  in  a  future  period  will  be  deferred  until  either:  (i)  the  customer  makes  up  the 

volumes or (ii) the likelihood that the customer will make up the volumes before the make up period expires becomes remote. 

If AltaGas does not expect the customer to make up the deficiency quantities (also referred to as breakage amount), AltaGas 

may recognize the expected breakage amount as revenue before the make up period expires. Significant judgment is required 

in  estimating  the  breakage  amount.  For  contracts  where  the  customer  has  no  make  up  rights,  revenue  is  recognized  on  a 

monthly  basis  based  on  the  higher  of  (i)  the  actual  quantity  delivered  times  the  per  unit  rate  or  (ii)  the  contracted  minimum 

amount.

Petrogas' storage fees are typically recognized in revenue ratably over the term of the contract and rail and truck loading and 

unloading fees are recognized when the volumes are delivered or received. 

Corporate/Other Segment

For the Corporate/Other segment, the majority of revenue relates to remaining power assets, from which revenue is primarily 

earned  through  power  purchase  agreements  which  are  accounted  for  as  operating  leases.  In  instances  where  power 

generation  is  not  sold  under  a  power  purchase  agreement,  the  commodity  is  sold  via  a  merchant  market,  or  via  commodity 

sales  agreements  which  are  accounted  for  as  financial  instruments.  For  commodity  sales  contracts  that  do  not  meet  the 

definition of a lease, derivative or for contracts whereby AltaGas has elected to apply the normal purchase normal sales scope 

exception,  the  sales  contract  is  accounted  for  under ASC  606.  This  includes  energy  generated  from  combined  heating  and 

power assets that are sold under long term power purchase agreements with a general duration of approximately 20 years. 

These long term purchase agreements provide stable cash flow by way of contracted prices for the underlying commodities.

Contract Balances

As at December 31, 2020, a contract asset of $51 million ($50 million net of credit losses) has been recorded within long-term 

investments  and  other  assets  on  the  Consolidated  Balance  Sheets  (December  31,  2019  –  $30  million).  This  contract  asset 

represents the difference in revenue recognized under a new rate in a blend-and-extend contract modification with a customer. 

Revenue from this contract modification will be recognized at the pre-modification rate for the remainder of the original term 

with the excess revenue recorded as a contract asset. The contract asset will be drawn down over the remaining term of the 

modified contract. 

In addition, at December 31, 2020 there is a contract asset of $21 million (December 31, 2019 - $59 million) recorded within 

prepaid expenses and other current assets on the Consolidated Balance Sheets for WGL Energy Systems’ unbilled revenue 

relating  to  design-build  construction  contracts. The  contract  asset  represents  unbilled  amounts  typically  resulting  from  sales 

under contracts when the cost-to-cost method of revenue recognition is utilized, and revenue recognized exceeds the amount 

billed to the customer. Right to payment is achieved when the projects are formally “accepted” by the federal government. At 

December 31, 2020, contract liabilities of $nil (December 31, 2019 - $2 million) have been recorded within accounts payable 

and accrued liabilities on the Consolidated Balance Sheets. The contract liabilities consisted of advance payments and billings 

in  excess  of  revenue  recognized  and  deferred  revenue.  Contract  assets  and  liabilities  are  reported  in  a  net  position  on  a 

contract-by-contract basis at the end of each reporting period.

AltaGas  applies  the  practical  expedient  available  under  ASC  606  and  does  not  disclose  information  about  the  remaining 

performance obligations for (i) contracts with an original expected length of one year or less, (ii) contracts for which revenue is 

recognized at the amount to which AltaGas has the right to invoice for performance completed, and (iii) contracts with variable 

consideration  that  is  allocated  entirely  to  a  wholly  unsatisfied  performance  obligation  or  to  a  wholly  unsatisfied  promise  to 

transfer  a  distinct  good  or  service  that  forms  part  of  a  single  performance  obligation.  In  addition,  the  table  above  does  not 

include  any  estimated  amounts  of  variable  consideration  that  are  constrained.  The  majority  of  midstream  service  contracts, 

gas  sales  and  transportation  service  contracts,  and  storage  service  contracts  contain  variable  consideration  whereby 

uncertainty  related  to  the  associated  variable  consideration  will  be  resolved  (usually  on  a  daily  basis)  as  volumes  are 

processed, gas is delivered or as service is provided. 

25.   Shareholders’ Equity

Authorization

AltaGas is authorized to issue an unlimited number of voting common shares. AltaGas is also authorized to issue such number 

of Preferred Shares in series at any time as have aggregate voting rights either directly or on conversion or exchange that in 

the  aggregate  represent  less  than  50  percent  of  the  voting  rights  attaching  to  the  then  issued  and  outstanding  Common 

Shares.

Dividend Reinvestment and Optional Cash Purchase Plan (DRIP or the Plan)

The Plan consisted of two components: a Dividend Reinvestment component and an Optional Cash Purchase component. The 

Premium  Dividend™  component  of  the  plan  was  suspended  in  December  2018.  The  Dividend  Reinvestment  and  Optional 

Cash Purchase component was suspended in December 2019, with the December dividend (paid January 2020) being the last 

dividend  payment  eligible  for  reinvestment  by  participating  shareholders  under  the  DRIP. The  Plan  in  its  entirety  will  remain

each of Series D Shares, Series F Shares, and up to 12,000,000 of Series L Shares, subject to certain conditions, upon conversion by the holders of the 

applicable currently issued and outstanding series of preferred shares noted opposite such series in the table on the applicable conversion option date. If

Shares, the holders of Series D Shares, Series F Shares, and Series L Shares will be entitled to receive a quarterly floating dividend as and when declared 

by the Board of Directors. 

(c)

AltaGas may, at its option, redeem all or a portion of the outstanding shares for the redemption price per share, plus all accrued and unpaid dividends on the 

applicable redemption option date and on every fifth anniversary thereafter. 

(d)

The holder will have the right, subject to certain conditions, to convert their preferred shares of a specified series into Preferred Shares of that other specified 

series as noted in this column of the table on the applicable conversion option date and every fifth anniversary thereafter. 

(e) Holders of Series A Shares, Series E Shares, and Series G Shares will be entitled to receive cumulative quarterly fixed dividends, which will reset on the

a rate equal to the sum of the then 90-day government of Canada Treasury Bill rate plus 2.66 percent (Series B Shares) and 3.06 percent (Series H Shares). 

Each quarterly dividend is calculated as the annualized amount multiplied by the number of days in the quarter, divided by the number of days in the year. 

Commencing  December  31,  2020,  the  floating  quarterly  dividend  rate  is  $0.17069  per  share  for  Series  B  Shares  and  $0.195349  per  share  for  Series  H 

Shares for the period starting December 31, 2020 to, but excluding, March 31, 2021.

Phantom Unit Plan (Phantom Plan) and Deferred Share Unit Plan (DSUP)

AltaGas  has  a  Phantom  Plan  for  employees  and  executive  officers,  which  includes  restricted  units  (RUs)  and  performance 

units  (PUs)  with  vesting  periods  of  36  to  44  months  from  the  grant  date.  In  addition,  AltaGas  has  a  DSUP,  which  allows 

granting  of  deferred  share  units  (DSUs)  to  directors.  DSUs  granted  under  the  DSUP  vest  immediately  but  settlement  of  the 

DSUs occur when the individual ceases to be a director.

28.   Pension Plans and Retiree Benefits 

The costs of the defined benefit and post-retirement benefit plans are based on Management's estimate of the future rate of 

return on the fair value of pension plan assets, salary escalations, mortality rates and other factors affecting the payment of 

future benefits. 

In 2020, AltaGas made a voluntary change in accounting principle for calculating the market-related value of assets used in the 

determination of Washington Gas' net periodic pension and other post-retirement benefit plan costs. This change in accounting 

principle impacts the calculation of net periodic benefit cost recorded within the line item “other income” on the Consolidated 

Statements of Income. Refer to Note 2 for additional information.

Defined Contribution Plan

AltaGas has a defined contribution (DC) pension plan for substantially all employees. The pension cost recorded for the DC 

plan was $21 million for the year ended December 31, 2020 (2019 - $20 million). 

Defined Benefit Plans 

AltaGas  has  several  defined  benefit  pension  plans  for  unionized  and  non-unionized  employees,  including  one  in  Canada 

(which is comprised of five divisions) and six in the United States. The plans in the United States include a qualified, trusteed, 

non-contributory  defined  benefit  pension  plan,  and  a  non-funded  defined  benefit  restoration  plan  maintained  by  Washington 

Gas.

The defined benefit plans are partially funded except for three of the divisions in Canada which are fully funded and one of the 

plans in the United States which is not funded.

AltaGas’  most  recent  actuarial  valuation  of  the  Canadian  defined  benefit  plans  for  funding  purposes  was  completed  for  the 

year ended December 31, 2019. AltaGas is required to file an actuarial valuation of its Canadian defined benefit plans with the 

pension regulators at least every three years. The next actuarial valuation for funding purposes is required to be completed as 

of  a  date  no  later  than  December  31,  2022,  and  will  be  filed  with  the  pension  regulators  in  2023.  Actuarial  valuations  for 

funding purposes are required annually for AltaGas’ U.S. defined benefit plans.

Supplemental Executive Retirement Plans (SERP)

AltaGas has non-registered, defined benefit plans that provide defined benefit pension benefits to eligible executives based on 

average  earnings,  years  of  service  and  age  at  retirement.  The  SERP  benefits  will  be  paid  from  the  general  revenue  of  the 

Corporation as payments come due or from the Rabbi Trusts funded as part of the WGL acquisition. Security will be provided 

for the SERP benefits through a letter of credit within a retirement compensation arrangement trust account. 

Several  executive  officers  of  Washington  Gas  participate  in  a  separate  non-funded  defined  benefit  SERP  (a  non-qualified 

pension plan). This defined benefit SERP was closed to new entrants beginning January 1, 2010. 

Post-Retirement Benefit Plans

AltaGas has several post-retirement benefit plans for unionized and non-unionized employees, including one in Canada and 

four in the United States. The post-retirement benefit plan in Canada is limited to the payment of life insurance and an annual 

allocation to a Healthcare Spending Account (HSA). This benefit plan is not funded. 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 139

Post-retirement benefit plans in the United States provide certain medical, prescription drug, dental, and life insurance benefits 

to eligible retired employees, their spouses and covered dependents. Benefits are based on a combination of the retiree's age 

and years of service at retirement. For eligible Washington Gas retirees and dependents not yet receiving Medicare benefits, 

Washington  Gas  provides  medical,  prescription  drug,  and  dental  benefits  through  Preferred  Provider  Organization  (PPO)  or 

Health  Maintenance  Organization  (HMO)  plans,  through  the  Washington  Gas  Light  Company  Retiree  Medical  Plan.  For 

Medicare-eligible  retirees  age  65  and  older  and  their  dependents,  eligible  retirees  and  dependents  participate  in  a  tax-free 

Health  Reimbursement  Account  (HRA)  Plan.  The  HRA  plan  provides  an  annual  subsidy  to  help  purchase  supplemental 

medical, prescription drug and dental coverage in the marketplace. One of these benefit plans is partially funded and three are 

fully funded.

Rabbi Trusts

Rabbi trusts of $28 million as at December 31, 2020 have been funded to satisfy the employee benefit obligations associated 

with WGL’s various pension plans (December 31, 2019 - $57 million). These balances are included in prepaid expenses and 

other current assets and long-term investments and other assets in the Consolidated Balance Sheets. 

The  following  table  summarizes  the  details  of  the  defined  benefit  plans,  including  the  SERP  and  post-retirement  plans  in 

Canada and the United States:

(a)    For post-retirement benefit plans, the projected benefit obligation represents the accumulated benefit obligation.

For  the  year  ended  December  31,  2020, AltaGas'  pension  plans  incurred  actuarial  losses  primarily  due  to  the  decrease  in 

discount  rates,  which  were  the  result  of  a  decline  in  high-quality  corporate  bond  yield  curves  in  the  Canadian  and  U.S. 

markets. For the year ended December, 31, 2019, AltaGas' defined benefit plans incurred actuarial losses for the same reason 

as mentioned above. AltaGas' post-retirement benefits plans incurred actuarial gains primarily due to updated census data and  

assumptions related to the HRA, partially offset by the decrease in discount rates.

The objective for fund returns, over three to five-year periods, is the sum of two components - a passive component, which is 

the benchmark index market returns for the asset mix in effect, plus the added value expected from active management. It is 

the Corporation’s belief that the potential additional returns justify the additional risk associated with active management. The 

risk  inherent  in  the  investment  strategy  over  a  market  cycle  (a three-to  five-year  period)  is  two-fold. There  is  a  risk  that  the 

market returns, as measured by the benchmark returns, will not be in line with expectations. The other risk is that the expected 

added value of active management over passive management will not be realized over the time period prescribed in each fund 

manager's mandate. There is also the risk of annual volatility in returns, which means that in any one year the actual return 

may be very different from the expected return.

Cash and money market investments may be held from time to time as short-term investment decisions at the discretion of the 

fund manager(s) within the constraints prescribed by their mandate(s).

The Corporation's target asset mix for the Canadian plans is 45 percent to 55 percent fixed income assets. The target asset 

mix for SEMCO plans is 33 percent fixed income assets and for WGL plans is 50 percent to 70 percent fixed income assets. 

These objectives have taken into account the nature of the liabilities and the risk-reward tolerance of the Corporation.

The collective investment mixes for the plans are as follows as at December 31, 2020:

The expected rate of return on assets is based on the current level of expected returns on risk free investments, the historical 

level  of  risk  premium  associated  with  other  asset  classes  in  which  the  portfolio  is  invested,  and  the  expectations  for  future 

returns of each asset class. The expected return for each asset class was then weighted based on the target asset allocation 

to develop the expected rate of return on assets assumption for the portfolio. 

The  discount  rate  is  based  on  yields  available  on  high-quality  long-term  corporate  bonds,  with  maturities  matching  the 

estimated timing and amount of expected benefit payments.

The estimates for health care benefits take into consideration increased health care benefits due to aging and cost increases 

in the future. The assumed health care cost trend rate used to measure the expected cost of benefits for the next year was 

between 2.2 and 6.0 percent. The health care cost trend rates were assumed to decline to between 2.2 and 4.5 percent by 

2027.

guaranteed  payments  for  certain  of  its  external  partners. As  at December  31,  2020, AltaGas  has  no  guarantees  to  external 

parties.

Contingencies

AltaGas and its subsidiaries are subject to various legal claims and actions arising in the normal course of business. While the 

final  outcome  of  such  legal  claims  and  actions  cannot  be  predicted  with  certainty,  the Corporation  does  not  believe  that  the 

resolution of such claims and actions will have a material impact on the Corporation’s consolidated financial position or results 

of operations. 

Antero Contract

In June 2019, a jury trial was held in the County Court for Denver, Colorado to consider a contractual dispute relating to gas 

pricing between Washington Gas and WGL Midstream (together, the Companies) and Antero Resources Corporation (Antero). 

Following  the  trial,  the  jury  returned  a  verdict  in  favor  of  Antero  for  approximately  US$96  million,  of  which  approximately 

US$11  million  was  against  Washington  Gas  with  the  remainder  against  WGL  Midstream.  Following  the  official  entry  of  the 

judgment, the Companies filed an appeal on August 16, 2019. On December 10, 2020, the Colorado Court of Appeals issued 

an unpublished opinion affirming the judgement of the trial court. No further appeal has been taken. The judgment was paid in 

full in February 2021, and a satisfaction has been filed with the court.

AltaGas recorded a net reduction to the acquired working capital of WGL of approximately US$45 million to account for the 

verdict  in  favor  of  Antero  net  of  tax  and  other  expected  recoveries.  Expected  recoveries  include  a  $18  million  receivable 

recorded  in  "long-term  investments  and  other  assets"  on  the  Consolidated  Balance  Sheets  for  amounts  expected  to  be 

recovered  under  a  commercial  arrangement  with  a  third  party  and  $7  million  recorded  in  "regulatory  assets"  on  the 

Consolidated Balance Sheets for amounts expected to be recovered from customers in future periods through the rate-setting 

process. 

During 2020, AltaGas entered into an Escrow Agreement and a Letter Agreement with the third party to share the cost related 

to the judgment. Following the execution of the agreements, $9 million funded by the third party was deposited into an escrow 

fund and recorded as restricted cash in “accounts receivable". The previously recorded receivable was reduced accordingly. 

Maryland Show-Cause Order

Following the National Transportation and Safety Board (NTSB) hearing that examined the August 10, 2016, explosion and fire 

at  an  apartment  complex  in  Silver  Spring,  Maryland,  on  September  5,  2019,  the  PSC  of  MD  ordered  Washington  Gas  to  (i) 

provide a detailed response to the NTSB’s probable cause findings and (ii) provide evidence regarding the status of a 2003 

mercury regulator replacement program and, if the program was not completed, to show cause why the PSC of MD should not 

impose a civil penalty on Washington Gas (Show-Cause Order). Following several hearings throughout the course of 2019 and 

AltaGas Ltd. – 2020 MD&A and Financial Statements - 148

2020, on December 18, 2020, the PSC of MD found that Washington Gas failed to file annual reports informing the PSC of MD 

of the status of Washington Gas' program and imposed a US$750,000 penalty on Washington Gas for reporting violations. The 

PSC of MD ruled that the NTSB probable cause finding constituted hearsay and could not be admitted into the record of the 

case and did not undertake its own inquiry into the source of the explosion. The PSC of MD did not make any safety-related 

findings  in  the  case  but  did  find  that  Washington  Gas  made  an  enforceable  regulatory  commitment  to  replace  all  mercury 

regulators. The US$750,000 penalty was paid in January 2021 and Washington Gas believes that there is no additional liability 

as a result of the ruling from the PSC of MD. In its December 18, 2020 order, the PSC of MD also found that Washington Gas’s 

proposed implementation plan to replace all remaining mercury regulators within five years of completing an mercury regulator 

survey adequately addresses the need to replace all remaining mercury regulators in Maryland, and is in the public interest. 

The costs of the proposed implementation program are not yet known, and the recovery of these costs must be deferred until a 

future rate case.

32.   Segmented Information

AltaGas owns and operates a portfolio of assets and services used to move energy from the source to the end‑user. In 2020, 
AltaGas revised its reportable segments to align with the structure of its business following asset sales completed as part of its 

2019  asset  monetization  program. As  a  result  of  these  changes, AltaGas  has  refocused  on  its  core  Utilities  and  Midstream 

segments. Consistent with Management’s strategic view of the business and the basis on which it assesses performance and 

allocates  resources,  beginning  in  2020,  AltaGas  has  two  operating  segments:  Utilities  (which  now  includes  the  WGL  retail 

marketing  business)  and  Midstream. These  operating  segments  have  not  been  aggregated  in  the  determination  of AltaGas' 

reportable segments. All other assets are included in the Corporate/Other segment. Prior period segment information has been 

restated to conform to the current reporting segment presentation. 

The following describes the Corporation’s reporting segments:

Utilities

Midstream

n	rate-regulated natural gas distribution assets in Michigan, Alaska, the District of Columbia, 
    Maryland, and Virginia;
n	rate-regulated natural gas storage in the United States; and
n	sale of natural gas to residential, commercial and industrial customers in Washington D.C., 
    Maryland, Virginia, Delaware, Pennsylvania and Ohio.

n	NGL processing and extraction plants;
n	natural gas storage facilities;
n	liquefied petroleum gas (LPG) terminals;
n	transmission pipelines to transport natural gas and NGL;
n	natural gas gathering lines and field processing facilities;
n	purchase and sale of natural gas;
n	natural gas and NGL marketing;
n	marketing, storage and distribution of wellsite fluids and fuels, crude oil and condensate diluents; and
n	interest in a regulated pipeline in the Marcellus/Utica gas formation; 

Corporate/
Other

n	the cost of providing corporate services, financing and general corporate overhead,
    investments in certain public and private entities, corporate assets, financing other segments and 
    the effects of changes in the fair value of certain risk management contracts; and
n	a small portfolio of remaining power assets, certain of which are pending sale.

A  degree  day  is  a  measure  of  coldness  determined  daily  as  the  number  of  degrees  the  average  temperature  during  the  day  in  question  is  below  65 

degrees  Fahrenheit.  Degree  days  for  a  particular  period  are  determined  by  adding  the  degree  days  incurred  during  each  day  of  the  period.  Normal 

degree days for a particular period are the average of degree days during the prior 15 years for SEMCO Gas, during the prior 10 years for ENSTAR, and 

during the prior 30 years for Washington Gas.

In  certain  of  Washington  Gas’  jurisdictions  (Virginia  and  Maryland)  there  are  billing  mechanisms  in  place  that  are  designed  to  eliminate  the  effects  of 

variance in customer usage caused by weather and other factors such as conservation. In the District of Columbia, there is no weather normalization 

billing  mechanism  nor  does  Washington  Gas  hedge  to  offset  the  effects  of  weather. As  a  result,  colder  or  warmer  weather  will  result  in  variances  to 

financial results.

exposed  volumes  plus  the  settlement  value  of  frac  hedges  settled  in  the  period  less  extraction  premiums,  divided  by  the  total  frac  exposed  volumes 

produced during the period.  

(10) Average  spot  frac  spread  or  NGL  margin,  expressed  in  dollars  per  barrel  of  NGL,  is  indicative  of  the  average  sales  price  that AltaGas  receives  for 

propane, butane and condensate less extraction premiums, before accounting for hedges, divided by the respective frac exposed volumes for the period. 

(11) Average propane price spread between FEI and Mont Belvieu TET commercial index for the period beginning May 2019.
