ALTAGAS REPORTS FOURTH QUARTER AND FULL YEAR 2023 RESULTS 

AltaGas Delivers on Full Year Guidance and Advances Key Strategic Priorities that will Drive 
Long-term Value Creation 

Calgary, Alberta (March 8, 2024) 

AltaGas Ltd. ("AltaGas" or the "Company") (TSX: ALA) reports fourth quarter and full year 2023 financial results, 

reaffirms 2024 financial guidance, and provides an update on its operations and other corporate developments. 

HIGHLIGHTS 

(all financial figures are unaudited and in Canadian dollars unless otherwise noted) 

▪  Normalized EBITDA1 was $502 million in the fourth quarter and $1,575 million for the full year of 2023, while income 
before income taxes was $161 million in the fourth quarter  and $912 million for the full year of 2023. Full-year 
normalized EBITDA was in the upper-half of the Company's 2023 guidance range of $1.5 billion - $1.6 billion and 
included strong performance across the Midstream platform and ongoing enterprise growth. 

▪  Normalized EPS1 was $0.76 in the fourth quarter and $1.90 for the full year of 2023, while GAAP EPS2 was $0.40 in 
the fourth quarter and $2.27 for the full year of 2023. Full year normalized EPS was slightly below the mid-point of 
the  Company's  2023  EPS  guidance  range  of  $1.85  -  $2.05,  principally  due  to  higher  interest  costs  weighing  on 
strong operating performance across the business. 

▪  Normalized FFO per share1 was $1.33 in the fourth quarter and $4.00 for the full year of 2023, while cash from 
operations per share3 was $0.54 in the fourth quarter and $3.98 for the full year of 2023. Normalized FFO per share 
for  the  quarter  increased  slightly  year-over-year  due  to  higher  normalized  EBITDA,  partially  offset  by  non-cash 
items included in normalized EBITDA, higher normalized current income tax expense, and higher interest expense. 

▪ 

▪ 

▪ 

The Utilities segment reported normalized EBITDA1 of $311 million in the fourth quarter of 2023 compared to $294 
million in the fourth quarter of 2022, while income before taxes was $207 million in the fourth quarter of 2023 
compared to  $80  million  in the fourth quarter  of 2022. The  largest drivers of the  fourth quarter year-over-year 
increase  were  strong  contributions  from  WGL’s  retail  business,  lower  operating  and  administrative  expenses, 
continued rate base growth, and the Virginia rate case. These positive factors were partially offset by the Company’s 
Alaska Utilities divestiture, lower asset optimization, and warmer weather in Michigan and the District of Columbia 
(“DC”). 

The Midstream segment reported normalized EBITDA1 of $182 million in the fourth quarter of 2023 compared to 
$163 million in the fourth quarter of 2022, while income before taxes in the segment was $79 million in the fourth 
quarter of 2023 compared to $113 million in the fourth quarter of 2022. The largest drivers of the fourth quarter 
year-over-year  increase  in  normalized  EBITDA1  included  strong  performance  from  the  global  exports  business, 
allowance for funds used during construction (“AFUDC”) on the Mountain Valley Pipeline project (“MVP”), and the 
absence of inventory write downs. 

The global exports business shipped 90,996 Bbl/d of liquified petroleum gases (“LPGs) in the fourth quarter of 2023 
and an average of 106,071 Bbls/d during 2023 from the Ridley Island Propane Export Terminal (“RIPET”) and the 
Ferndale terminal (“Ferndale”). Although the fourth quarter is a seasonally low quarter for exports, volumes were 
below  internal  expectations  this  quarter  due  to  delayed  ship  arrivals  at  both  terminals  during  December  2023, 
which were loaded in the first quarter of 2024. Despite these timing impacts in the fourth quarter, AltaGas continued

to  demonstrate  the  multi-year  growth  trajectory  that  has  been  demonstrated  since  2019  while  connecting  the 
Canadian upstream and Asian downstream markets and driving stronger Canadian industry netbacks.  

▪  On December 22, 2023, AltaGas closed the acquisition of natural gas processing and storage infrastructure assets 
in  the  Pipestone  area  of  the  Alberta  Montney  (the  “Pipestone  Acquisition”),  including  Pipestone  natural  gas 
processing plant phase I (“Pipestone Phase I”), the Pipestone Phase I expansion project (“Pipestone Phase II”), the 
Dimsdale  natural  gas  storage  facility,  and  ancillary  assets  from  Tidewater  Midstream  and  Infrastructure  Ltd. 
("Tidewater").  AltaGas  also  declared  a  positive  final  investment  decision  ("FID")  on  Pipestone  Phase  II  with  100 
percent of the capacity contracted under long-term take-or-pay agreements.  

▪  AltaGas  continued  to  advance  key  activities  on  the  Ridley  Island  Energy  Export  Facility  (“REEF”)  during  and 
subsequent to the fourth quarter of 2023. This included commencing site clearing work, including logging, clearing, 
and drainage work that will further solidify the project’s readiness to reaching FID, which is expected during the 
second quarter of 2024. 

▪ 

In December 2023, AltaGas commissioned the first of two new very large gas carriers (“VLGCs”), the Boreal Pioneer, 
which made its maiden voyage from Ferndale to Asia in early January 2024. The second VLGC, the Boreal Voyager, 
was commissioned in February 2024. These two seven-year time charters with optional extensions will reduce and 
de-risk  shipping  costs  with  materially  all  of  AltaGas’  expected  Baltic  freight  exposure  protected  through  time 
charters, financial hedges, and tolled volumes in 2024. 

▪  On  October  20,  2023,  Washington  Gas  executed  a  definitive  agreement  with  Opal  Fuels  Inc.  (“Opal  Fuels”)  to 
support a renewable natural gas (“RNG”) project at the Prince William County Landfill in Virginia. As part of the 
agreement, Washington Gas will become an offtake customer for RNG production and purchase key interconnect 
infrastructure for approximately US$25 million and continue to advance long-term climate goals.  

▪  On December 14, 2023, the Public Service Commission of Maryland (“PSC of MD”) approved a US$10 million rate 
increase  with  a  9.5  percent  return  on  equity  and  52  percent  equity  thickness.  The  new  rates  became  effective 
immediately. 

▪  On  December  22,  2023,  the  Public  Service  Commission  of  the  District  of  Columbia  (“PSC  of  DC”)  approved  an 
increase of approximately US$20 million in revenues, net of approximately US$5 million of costs collected through 
the PROJECTpipes surcharge. This included a 9.65 percent return on equity and 52 percent equity thickness. The 
new rates went into effect January 19, 2024. 

▪  On March 1, 2023, AltaGas closed the divestiture of its Alaskan Utilities for US$800 million (approximately CAD$1.1 
billion), prior to  closing adjustments. Sale proceeds were used to  reduce debt while providing AltaGas with the 
financial flexibility to advance its strong growth opportunities across the Midstream and Utilities platforms over the 
coming years. 

▪  On  December  5,  2023,  AltaGas’  Board  of  Directors  approved  a  6  percent  increase  to  its  annual  common  share 
dividends to $1.19 per common share annually ($0.2975 per common share quarterly). This change will be effective 
for the dividend that will be paid on March 29, 2024, with long-term dividends expected to continue to compound 
by five to seven percent per annum in the years ahead, subject to annual Board approval.  

▪  On December 5, 2023, AltaGas released its 2023 ESG Report, highlighting 2022 data for key topics and outlining 
progress towards the Company’s sustainability goals within the areas of climate, diversity and inclusion and safety. 

▪  AltaGas is pleased with the construction progress on MVP. The pipeline is now 99 percent complete and expected 
to be placed into service in the second quarter of 2024 and will provide critical energy security to customers in the 
Eastern U.S. As previously disclosed, AltaGas does not consider its equity stake in MVP as core and will consider 
value  maximizing opportunities as part of  the Company’s plan to  reach its 4.5x  net debt to  normalized  EBITDA 
target once the pipeline is fully operational.

▪  AltaGas had a series of financing during and subsequent to the fourth quarter, including: 

•  On  October  19,  2023,  Washington  Gas  issued  US$200  million  in  private  placement  notes,  which 
includes US$150 million of notes with a 6.06 percent interest rate, maturing on October 14, 2033, and 
US$50 million of notes at a 6.43 percent interest rate, maturing on October 15, 2053. 

•  On  November  10,  2023,  AltaGas  issued  $200  million  of  Hybrid  8.90  percent  Fixed-to-Fixed  Rate 
Subordinated  Notes,  Series  3,  due  November  10,  2083.  On  December  31,  2023,  AltaGas  used  the 
proceeds of the hybrid issuance to redeem all of its issued and outstanding Series E Preferred Shares 
for $25 per Series E Share, together with all accrued and unpaid dividends.  

•  On January 8, 2024, AltaGas issued $400 million of senior unsecured medium-term notes with a 4.67 
percent coupon. The net proceeds were used to pay down existing indebtedness under AltaGas' credit 
facilities (part of which was incurred to fund the debt portion of the Pipestone Acquisition), to fund 
working capital, and for general corporate purposes. 

▪  AltaGas is reiterating the Company’s 2024 full year guidance, including normalized EBITDA1 of $1,675 million to 

$1,775 million, and normalized EPS1 of $2.05 - $2.25. 

CEO MESSAGE 

“We are pleased with the results delivered during 2023,” said Vern Yu, President and Chief Executive Officer of AltaGas. 
“The performance demonstrates the strength of our platform and the actions we have taken to drive long-term value.  

“Fourth  quarter  Midstream  performance  was  strong  with  normalized  EBITDA  up  12  percent  year-over-year,  despite 
delays  on  two  LPG  export  vessels  that  had  loadings  pushed  into  the  first  quarter  of  2024.  Canadian  upstream 
development remains strong as the industry prepares for improved egress and the arrival of LNG Canada.  This was 
reflected in AltaGas realizing higher year-over-year throughput volumes across our gas processing, fractionation, and 
liquids handling businesses during the fourth quarter, as we fill latent capacity and prepare for potential brownfield 
expansions to support industry development. 

“The  recent  issues  in  the  Panama  Canal  reiterated  the  importance  of  connecting  Canadian  LPGs  to  key  Asian 
downstream  markets  and  the  mutual  benefits  of  a  growing  Canadian-Pacific  energy  partnership.  We  estimate  that 
Canadian producers realized an approximate US$9.50 per barrel better propane netback through long-term tolling at 
RIPET during the fourth quarter compared to selling domestically in the U.S. 

“Despite warmer weather in Michigan and DC, the Utilities performed relatively in line with our expectations and were 
aided by strong performance from the Retail platform in the fourth quarter. Our Utilities are critical to balancing long-
term energy reliability, affordability, and climate needs across our jurisdictions and have a bright future as the largest 
home heating source across each jurisdiction.  

“The past year was an active period for AltaGas, including the Pipestone Acquisition, solidifying our REEF joint-venture, 
closing the Alaskan Utilities sale, advancing key Midstream commercial de-risking initiatives, and continuing to steadily 
grow our Utilities. I am excited about the road ahead, continuing to leverage the strong long-term fundamentals for 
natural gas and natural gas liquids (“NGLs”), and building on the strong successes of 2023.”

The Midstream segment reported normalized EBITDA of $182 million in the fourth quarter of 2023 compared to $163 
million in the fourth quarter in 2022, while income before taxes was $79 million in the fourth quarter of 2023 compared 
to $113 million in the fourth quarter of 2022. The year-over-year increase in normalized EBITDA in the fourth quarter 
of 2023 was driven by strong performance from the global exports business, contribution from AFUDC on MVP as the 
pipeline moves towards completion, strong marketing performance, and lower operating expenses across a number of 
businesses. These factors were partially offset by lower frac spreads and volumes at the extraction facilities, lower power 
revenue at Harmattan due to power prices, and the absence of the certain acquisition related commercial disputes and 
contingencies present in the fourth quarter of 2022. 

Fourth quarter 2023 results included a year-over-year improvement in the profitability of the global exports business 
due to stronger Asian-to-North American LPG prices during the quarter. This was partially offset by lower merchant 
volumes  as  AltaGas  was  successful  at  increasing  long-term  tolling,  merchant  volumes  being  highly  hedged  in  the 
quarter, and lower-than-expected overall export volumes. AltaGas exported 90,996 Bbls/d of LPGs to Asia during the 
fourth  quarter  of  2023,  including  ten  VLGCs  at  RIPET,  and  five  VLGCs  at  Ferndale.  Although  global  export  volumes 
traditionally realize lower volumes in the fourth quarter due to a lack of LPG supply coming from Washington refineries 
at  Ferndale  and  weather-related  impacts  on  logistics,  volumes  were  lower-than-expected  due  to  one  delayed  ship 
arrival at RIPET and one delayed ship at Ferndale due to a rail outage. 

Over  the  longer-term,  AltaGas  continues  to  see  growing  demand  for  LPG  exports  driven  by  its  structural  shipping 
advantage to Asia and access to low-cost Canadian supply. This structural advantage has amplified recently due to the 
restricted vessel traffic through the Panama Canal, which is driving additional demand for reliable and ratably-sourced 
Canadian LPGs and highlights the mutual benefits of a growing Canadian-Pacific energy partnership. AltaGas estimates 
that Canadian producers realized an approximate US$9.50 per barrel better propane netback through long-term tolling 
at RIPET during the fourth quarter of 2023 compared to selling domestically in the U.S. at Conway. 

Performance across the balance of the Midstream platform was strong and in line with the Company’s expectations 
during the fourth quarter. This included strong year-over-year volume increases at Townsend and Harmattan and nine 
percent year-over-year growth  across AltaGas’ Montney footprint  during  the quarter.  This demonstrates  the strong

resumption  of  development  activity  in  the  basin  and  the  Montney  being  at  the  center  of  the  long-term  basin 
development plans. Fractionation volumes were up four percent year-over-year during the fourth quarter of 2023, due 
to  higher  volumes  at  Harmattan,  Younger,  and  North  Pine.  AltaGas'  realized  frac  spread  averaged  $23.13/Bbl,  after 
transportation costs, as most of AltaGas' frac exposed volumes were hedged in the fourth quarter of 2023. 

AltaGas is well-hedged for 2024 with 90 percent of full year 2024 expected global export volumes tolled or financially 
hedged with merchant volumes hedged at an average Far East Index (“FEI”) to North American financial hedge price of 
approximately US$17.88/Bbl. This includes AltaGas entering the year with approximately 40 percent of global exports 
tolled with the expectation of being 50 percent tolled or higher by the end of 2024. Based on AltaGas’ signed deals 
and existing customer conversations, the Company expects to achieve or exceed this level of tolling. Approximately 80 
percent of the Company’s 2024 expected frac exposed volumes are hedged at approximately US$27.04/Bbl, prior to 
transportation  costs. AltaGas continues  to  actively manage risk  across the  Midstream platform  through  commercial 
constructs and a systematic hedging program that covers key revenue and operating costs. 

In December 2023, AltaGas commissioned the first of two VLGCs, the Boreal Pioneer, which made its maiden voyage 
from Ferndale to Asia in early January 2024. The second VLGC, the Boreal Voyager, was commissioned in February 2024. 
These two seven-year time charters with optional extensions will reduce total shipping costs to Asia by approximately 
25 percent compared to a standard VLGC. These two seven-year time charters, combined with financial hedges, and 
tolled volumes have principally eliminated AltaGas’ expected Baltic freight exposure in 2024.

Utilities 

Normalized EBITDA in the Utilities segment was $311 million in the fourth quarter of 2023, compared to $294 million 
in the same quarter in 2022 while income before taxes was $207 million in the fourth quarter of 2023 compared to $80 
million in the fourth quarter of 2022. The quarter included strong performance from WGL's retail marketing business, 
customer  growth,  higher  revenue  from  rate  base  additions  from  ongoing  investments  in  Accelerated  Replacement 
Programs (“ARPs”), the impact of Washington Gas' Virginia rate case, and lower operating and administrative expenses. 
These  factors were partially offset by the  lost contribution of the Alaskan Utilities, which were divested in March of 
2023, and had contributed $25 million of normalized EBITDA in the fourth quarter of 2022, larger-than-normal asset 
optimization contribution at Washington Gas in the fourth quarter of 2022, and warmer weather in Michigan and the 
DC during the fourth quarter of 2023, which do not have weather normalization or decoupled rate structures. Other 
positive  factors  impacting  year-over-year  normalized  EBITDA  included  foreign  exchange  hedge  gains  and  lower 
operating and administrative expenses. 

AltaGas’ continues to make investment across its Utilities network to improve the safety and reliability of the system 
on behalf of its customers. During the fourth quarter of 2023 AltaGas invested $192 million across the Utilities network, 
including  $130  million  across  the  Company’s  various  modernization  programs.  These  investments  continue  to  be 
directed towards improving the safety and reliability of the system and connecting customers to the critical energy they 
require to carry out everyday life. These investments should also reduce leak rates and bring long-term operating cost 
benefits  to  our  customers.  AltaGas  will  continue  to  make  these  critical  investments,  while  balancing  the  need  for 

AltaGas Ltd. – Press Release Q4 2023

ongoing  customer  affordability,  which  is  particularly  important  during  the  current  economic  environment  of  higher 
interest rates and inflation. AltaGas continues to be acutely focused on cost management across the Utilities platform, 
managing capital investments, and driving the best outcomes for its customers and stakeholders. 

During the quarter, Washington Gas had three major regulatory updates. The first was a proposed ARP modernization 
extension in Maryland, which will run through to 2028. The public law judge has recommended that the  PSC of MD 
approve approximately US$330 million of capital to modernize our system and improve safety and reliability. This builds 
on AltaGas’ ARP program in Virginia that was recently extended to the end of 2027. The second was the PSC of MD 
approving a US$10 million rate increase for Washington Gas in Maryland with a 9.5 percent return on equity and 52 
percent equity thickness with the new rates becoming effective immediately. Lastly, the PSC of DC approved an increase 
of  approximately  US$20  million  in  revenues  for  Washington  Gas  in  DC,  net  of  approximately  US$5  million  of  costs 
collected through the PROJECTpipes surcharge with the new rates effective January 19, 2024. 

Corporate/Other 

Normalized EBITDA in the Corporate/Other segment was $9 million for the fourth quarter of 2023, compared to a loss 
of $3 million in the same quarter of 2022.  Loss before income taxes in the Corporate/Other segment was $125 million 
in the fourth quarter of 2023, compared to $115 million in the same quarter of 2022. The largest drivers for the increase 
in normalized EBITDA was due to lower expenses related to employee incentive plans and lower corporate operating 
and administrative expenses. 

Pipestone Asset Acquisition 

On December 22, 2023, AltaGas closed the previously announced Pipestone Acquisition and declared a positive FID on 
Pipestone Phase II. The assets acquired through the Pipestone Acquisition included: 1) Pipestone Phase I and Pipestone 
Phase II; 2) the adjacent Dimsdale natural gas storage facility; 3) the Pipestone condensate truck-in/truck-out terminal; 
and 4) the associated gathering pipeline systems from Tidewater.  

The Pipestone Phase II expansion project was 100 percent contracted under long-term take-or-pay agreements during 
the fourth quarter of 2023 with a combination of marquee independents and investment grade producers. All Pipestone 
Phase II customers who were existing Pipestone Phase I customers also agreed to multi-year contract extensions, further 
improving the long-term commercial profile of the Pipestone Assets. 

With inclusion of these new agreements, the Pipestone Acquisition is constructive to our risk profile with the Company's 
take-or-pay and fee-for-service Midstream EBITDA mix set to increase by an estimated six percent with a commensurate 
decrease in commodity exposed EBITDA, once Pipestone Phase II comes online. In aggregate, more than 90 percent of 
the Pipestone Assets' normalized EBITDA1 is expected to come from take-or-pay or fee-for-service based contracts. 

The Pipestone Assets have been integrated and AltaGas has welcomed its new employees that joined the Company as 
part of the transaction. AltaGas is now focused on leveraging the long-term growth opportunities and delivering on 
the returns that can be generated with the Pipestone assets now part of AltaGas’ value chain. The Company is pleased 
with the transition of operatorship and progress realized to date.

"Other"  includes  accretion  expense,  net  income  applicable  to  non-controlling  interests,  foreign  exchange  gains  (loses),  unrealized  foreign  exchange  losses  on 
intercompany balances, and NCI portion of non-GAAP adjustments. The portion of non-GAAP adjustments applicable to non-controlling interests are excluded in 
the computation of normalized net income to ensure consistency of normalizations applied to controlling and non-controlling interests. These amounts are included 
in the “net income applicable to non-controlling interests” line item on the Consolidated Statements of Income. 
In the fourth quarter of 2023, AltaGas changed its non-GAAP policy to exclude the impact of unrealized foreign exchange losses (gains) on intercompany balances 
between Canadian and U.S. entities. Prior periods have been restated to reflect this change. Please refer to the Non-GAAP Financial Measures section of this news 
release for additional details.  

3) 

4)  Weighted average. 

Normalized EBITDA for the fourth quarter of 2023 was $502 million, compared to $454 million for the same quarter in 
2022.  The  largest  contributors  impacting  the  year-over-year  increase  are  described  in  the  Business  Performance 
sections above. 

For the fourth quarter of 2023, the average Canadian/U.S. dollar exchange rate increased to 1.362 from an average of 
1.358 in the same period of 2022. 

Income before income taxes for the fourth quarter of 2023 was $161 million, compared to $78 million for the same 
quarter in 2022. The increase was mainly due to higher normalized EBITDA, lower unrealized losses on risk management 
contracts, and the absence of provisions on assets, partially offset by higher foreign exchange losses and costs related 
to the CEO transition and other restructuring costs incurred in 2023. Please refer to the “Three Months Ended December 
31” section of AltaGas’ Q4 2023 management’s discussion and analysis (“MD&A”) for further details on the variance in 
income before income taxes and net income applicable to common shareholders.  

Normalized net income was $214 million ($0.76 per share) for the fourth quarter of 2023, compared to $189 million 
($0.67 per share) reported for the same quarter in 2022. The increase was mainly due to  higher normalized EBITDA,

partially offset by higher foreign exchange losses and higher normalized income tax expense. Please refer to the “Non-
GAAP Financial Measures” section of AltaGas’ Q4 2023 MD&A for further details on normalization adjustments  

Normalized funds from operations for the fourth quarter of 2023 was $376 million ($1.33 per share), compared to $371 
million  ($1.32  per  share)  for  the  same  quarter  in  2022.  The  increase  was  mainly  due  to  higher  normalized  EBITDA, 
partially offset by the impact of non-cash items included in normalized EBITDA, higher normalized current income tax 
expense, and higher interest expense. 

Depreciation and amortization expense for the fourth quarter of 2023 was $110 million, compared to $112 million for 
the same quarter in 2022. The decrease was due to the impact of the disposition of the Alaskan Utilities, partially offset 
by new assets placed in-service. 

Interest expense for the fourth quarter of 2023 was $101 million, compared to $99 million for the same quarter in 2022. 
The slight increase was due to $3 million of incremental hybrid interest costs compared to the same quarter in 2022 
due to hybrid notes replacing preferred shares. Excluding the impact of shifting the financing costs between preferred 
shares and hybrid notes, interest costs were relatively comparable. 

AltaGas recorded income tax expense of $33 million for the fourth quarter of 2023 compared to $12 million in the same 
quarter in 2022. The increase in income tax expense was mainly due to an increase in income before income taxes in 
the fourth quarter of 2023 compared to the same quarter in 2022.  

FORWARD FOCUS, GUIDANCE AND FUNDING  

AltaGas continues to execute on its long-term corporate strategy of building a diversified platform that operates long-
life  energy  infrastructure  assets  that  connect  customers  and  markets  and  are  positioned  to  provide  resilient  and 
growing value for the Company’s stakeholders. 

AltaGas expects to achieve its previously disclosed 2024 guidance, including:  

•  2024 normalized EPS guidance of $2.05 - $2.25, compared to normalized EPS of $1.90 and GAAP EPS of $2.27 

in 2023; and 

•  2024 normalized EBITDA guidance of $1,675 million - $1,775 million, compared to normalized EBITDA of $1,575 

million and income before taxes of $912 million in 2023.  

AltaGas  is  focused  on  delivering  resilient  and  growing  normalized  EPS  and  FFO  per  share  while  targeting  lowering 
leverage ratios. This strategy is designed to support steady dividend growth and provide the opportunity for ongoing 
capital appreciation for long-term shareholders. In December, the Board of Directors approved a six percent increase 
to the annual common share dividend to $1.19 per share annually for the 2024 calendar year, which equates to a rate 
of  $0.2975  per  common  share  on  a  quarterly  basis.  AltaGas’  strategy  includes  plans  to  deliver  sustainable  annual 
dividend increases that compound in the years ahead.  

AltaGas  is  maintaining  a  disciplined,  self-funded  capital  program  of  approximately  $1.2  billion,  excluding  asset 
retirement  obligations  (“ARO”).  The  Company  is  allocating  approximately  58  percent  of  AltaGas’  consolidated  2024 
capital  to  its  Utilities  business,  approximately  36  percent  to  the  Midstream  business  and  the  balance  to  the 
Corporate/Other segment.    

The Company expects to maintain an equity self-funding model in 2024, for the fifth consecutive year, and will fund 
capital requirements through a combination of internally generated cash flows and investment capacity associated with 
rising EBITDA levels, with no expectation to issue equity. Asset sales will be considered on an opportunistic basis, with 
any potential proceeds to  be used to  de-lever  and strengthen the balance sheet and continue to  increase  financial 
flexibility of AltaGas.

NON-GAAP MEASURES  

This news release contains references to certain financial measures that do not have a standardized meaning prescribed 
by US GAAP and may not be comparable to similar measures presented by other entities. The non-GAAP measures and 
their reconciliation to US GAAP financial measures are shown below and within AltaGas’ MD&A as at and for the period 
ended  December  31,  2023.  These  non-GAAP  measures  provide  additional  information  that  management  of  the 
Company (“Management”) believes is meaningful regarding AltaGas' operational performance, liquidity and capacity 
to  fund  dividends,  capital  expenditures,  and  other  investing  activities.  Readers  are  cautioned  that  these  non-GAAP 
measures should not be construed as alternatives to other measures of financial performance calculated in accordance 
with US GAAP. 

Change in Composition of Non-GAAP Measures 

In the fourth quarter of 2023, Management has changed the composition of certain of AltaGas' non-GAAP measures 
such that normalized net income now excludes the impact of unrealized intercompany foreign exchange gains (losses) 

AltaGas Ltd. – Press Release Q4 2023

resulting from intercompany balances between a U.S. subsidiary and a Canadian entity, where the foreign exchange 
impact  in  the  U.S.  subsidiary  is  recorded  through  gain  (loss)  on  foreign  currency  translation  in  the  Consolidated 
Statements of Comprehensive Income and the Canadian entity revaluation is recorded through the foreign exchange 
gain (loss) line item on the Consolidated Statements of Income. This change was made as a result of Management's 
assessment  that  excluding  these  intercompany  foreign  exchange  impacts  from  normalized  net  income  is  more 
representative of the Company's ongoing financial performance. Prior period calculations of the relevant non-GAAP 
measures have been restated to reflect this change. The following table summarizes the impact of this change on the 
periods presented in this news release:

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 (Loss) using income 
(loss) before income taxes adjusted for pre‑tax depreciation and amortization, interest expense. 

AltaGas  presents  normalized  EBITDA  as  a  supplemental  measure.  Normalized  EBITDA  is  used  by  Management  to 
enhance  the  understanding  of  AltaGas'  earnings  over  periods,  as  well  as  for  budgeting  and  compensation  related 
purposes. The metric is frequently used by analysts and investors in the evaluation of entities within the industry as it 
excludes items that can vary substantially between entities depending  on the accounting policies chosen, the book 
value of assets, and the capital structure.

intercompany balances between Canadian and U.S. entities. The amounts presented in this table reflect the restated figures to align with the revised policy.) 

Normalized net income and normalized net income per share are used by Management to enhance the comparability 
of AltaGas’ earnings, as these metrics reflect the underlying performance of AltaGas’ business activities.

(2)  AFUDC is the amount that a rate-regulated enterprise is allowed to recover for its cost of financing assets under construction and is included in the "property,

Includes only the cash portion of the total consideration paid for the Pipestone Acquisition, net of cash acquired.

(4)  Relates to escrow account proceeds received from AltaGas' previous investment in Central Penn. Upon close of the sale in 2019, various escrow accounts were 

(5) 

established to provide the purchaser a form of recourse for the settlement of indemnification obligations.  
In the fourth quarter of 2023, AltaGas changed its non-GAAP policy to exclude cash paid for business acquisitions and for the purchase of remaining non-
controlling interest in a subsidiary from invested capital. Prior periods have been restated to reflect this change.  

Invested capital is a measure of AltaGas' use of funds for capital expenditure activities. It includes expenditures relating 
to  property,  plant,  and  equipment  and  intangible  assets,  capital  contributed  to  long  term  investments,  and 
contributions  from  non-controlling  interests.  Net  invested  capital  is  invested  capital  presented  net  of  cash  paid  for 
business acquisitions, cash paid for the purchase of remaining non-controlling interest in a subsidiary, and proceeds 
from disposals of assets and equity investments in the period. Net invested capital is calculated based on the investing

AltaGas Business Overview and Organization

AltaGas is a leading North American energy infrastructure company that connects customers and markets to affordable and 

reliable sources of energy. The Company operates a diversified, lower-risk, high-growth energy infrastructure business that is 

focused  on  delivering  resilient  and  durable  value  for  its  stakeholders.  AltaGas  has  three  reporting  segments  -  Utilities, 

Midstream, and Corporate/Other. 

Utilities Segment

AltaGas'  Utilities  segment owns  and  operates  franchised,  cost-of-service,  rate-regulated  natural  gas  distribution  and  storage 

utilities that are focused on providing safe, reliable, and affordable energy to its customers. AltaGas' Utilities provided energy to 

approximately 1.6 million residential and commercial customers in 2023 with an average rate base of approximately US$5.1 

billion.

The Utilities segment includes two utilities that operate across four major U.S. jurisdictions:

▪ Washington  Gas  Light  Company  ("Washington  Gas"),  which  is  the  Company’s  largest  operating  utility  that  serves 

approximately 1.2 million customers across Maryland, Virginia, and the District of Columbia; and

▪

SEMCO  Energy,  Inc.  ("SEMCO  Energy"),  which  delivers  essential  energy  to  approximately  328,000  customers  in 

Southern Michigan and Michigan’s Upper Peninsula.

The Utilities business also includes other storage facilities and contracts for interstate natural gas transportation and storage 

services, as well as WGL Energy Services, an affiliated retail energy marketing business, which sells natural gas and electricity 

directly to residential, commercial, and industrial customers located in Maryland, Virginia, Delaware, Pennsylvania, Ohio, and 

the District of Columbia. AltaGas also previously owned ENSTAR Natural Gas Company and a 65 percent indirect interest in 

Cook Inlet Natural Gas Storage Alaska ("CINGSA") and other ancillary operations in Alaska, which were divested to TriSummit 

Utilities Inc. on March 1, 2023 (the "Alaska Utilities Disposition"). 

Midstream Segment

AltaGas’  Midstream  segment  is  a leading  North American  platform  that  connects  customers  and  markets.  From  wellhead  to 

tidewater, the Company is focused on providing its customers with safe and reliable service and connectivity that facilitates the 

best  outcomes  for  their  businesses.  This  includes  global  market  access  for  North  American  Liquified  Petroleum  Gases 

("LPGs"),  which  provides  North American  producers  and  aggregators  with  attractive  netbacks  for  propane  and  butane  while 

delivering diversity of supply and supporting stronger energy security in Asia to AltaGas' downstream customers.

Throughout AltaGas’ Midstream operations, the Company is playing a vital role within the larger energy ecosystem that keeps 

the global economy moving forward in a safe, reliable, and affordable manner.

AltaGas’  Midstream  platform  is  heavily  focused  on  the  Montney  and  Deep  Basin  resource  plays  and  centers  around  global 

exports, which is where the Company believes the market is headed for Canadian resource development over the long-term. 

AltaGas  also  operates  a  broader  set  of  midstream  infrastructure  assets  across  the  Western  Canadian  Sedimentary  Basin

Fourth Quarter and Full Year 2023 Highlights
(Normalized  EBITDA,  normalized  funds  from  operations,  normalized  net  income,  and  net  debt  are  non-GAAP  financial  measures.  Normalized  funds  from 
operations per share and normalized net income per share are non-GAAP ratios. Please see Non-GAAP Financial Measures section of this MD&A.)

Financial and Operational Highlights 

▪

▪

▪

▪

▪

▪

▪

Normalized EBITDA was $502 million in the fourth quarter and $1,575 million for the full year of 2023, while income 

before  income  taxes  was  $161  million  in  the  fourth  quarter  and  $912  million  for  the  full  year  of  2023.  Full  year 

normalized EBITDA was in the upper-half of the Company's 2023 guidance range of $1.5 billion to $1.6 billion and 

included strong performance across the Midstream platform and ongoing enterprise growth.  

Normalized net income per share was $0.76 in the fourth quarter and $1.90 for the full year of 2023, while GAAP net 

income per share was $0.40 in the fourth quarter and $2.27 for the full year of 2023. Full year normalized net income 

per share was slightly below the mid-point of the Company's 2023 net income per share guidance range of $1.85 to 

$2.05, principally due to higher interest costs weighing on strong operating performance across the business.

Normalized funds from operation per share was $1.33 in the fourth quarter and $4.00 for the full year of 2023, while 

cash from operations per share was $0.54 in the fourth quarter and $3.98 for the full year of 2023. Normalized funds 

from operations per share for the quarter increased slightly year-over-year due to higher normalized EBITDA, partially 

offset by non-cash items included in normalized EBITDA, higher normalized current income tax expense, and higher 

interest expense.

The  Utilities  segment  reported  normalized  EBITDA  of  $311  million  in  the  fourth  quarter  of  2023  compared  to  $294 

million  in  the  fourth  quarter  of  2022,  while  income  before  taxes  was  $207  million  in  the  fourth  quarter  of  2023 

compared to $80 million in the fourth quarter of 2022. The largest drivers of the fourth quarter year-over-year increase 

in  normalized  EBITDA  were  strong  contributions  from  WGL's  retail  business,  lower  operating  and  administrative 

expenses, continued rate base growth, and the Virginia rate case. These positive factors were partially offset by the 

Alaska  Utilities  divestiture,  lower  asset  optimization,  and  warmer  weather  in  Michigan  and  the  District  of  Columbia 

("DC").

The Midstream segment reported normalized EBITDA of $182 million in the fourth quarter of 2023 compared to $163 

million in the fourth quarter of 2022, while income before taxes in the segment was $79 million in the fourth quarter of 

2023 compared to $113 million in the fourth quarter of 2022. The largest drivers of the fourth quarter year-over-year 

increase in normalized EBITDA included strong performance from the global exports business, Allowance for Funds 

Used During Construction ("AFUDC") on the MVP project, and the absence of inventory write downs.

On March 1, 2023, AltaGas closed the Alaska Utilities Disposition for consideration of approximately US$800 million 

(approximately CAD$1.1 billion) prior to closing adjustments, resulting in a pre-tax gain of approximately $304 million. 

Sale  proceeds  were  used  to  reduce  debt  while  providing AltaGas  with  the  financial  flexibility  to  advance  its  strong 

growth opportunities across the Midstream and Utilities platforms over the coming years.

The global exports business shipped 90,996 Bbl/d of liquified petroleum gases ("LPGs") in the fourth quarter of 2023 

and  an  average  of  106,071  Bbls/d  during  2023  from  the  Ridley  Island  Propane  Export  Terminal  ("RIPET")  and  the 

Ferndale  terminal  ("Ferndale").  Although  the  fourth  quarter  is  a  seasonally  low  quarter  for  exports,  volumes  were 

below internal expectations this quarter due to delayed ship arrivals at both terminals during December 2023, which 

were loaded in the first quarter of 2024. Despite these timing effects, AltaGas continued to demonstrate the multi-year

growth  trajectory  since  2019  while  connecting  the  Canadian  upstream  and Asian  downstream  markets  and driving 

stronger Canadian industry netbacks. 

On December 22, 2023, AltaGas closed the previously announced acquisition of natural gas processing and storage 

infrastructure  assets  in  the  Pipestone  area  of  the  Alberta  Montney  (the  "Pipestone  Acquisition"),  including  the 

Pipestone natural gas processing facility Phase I ("Pipestone Phase I"), the Pipestone natural gas processing facility 

Phase II expansion project ("Pipestone Phase II"), the Dimsdale storage facility, and ancillary assets from Tidewater 

Midstream and Infrastructure Ltd. ("Tidewater"). AltaGas also declared a positive final investment decision ("FID") on 

Pipestone Phase II with 100 percent of the capacity contracted under long-term take-or-pay agreements. 

AltaGas  continued  to  advance  key  activities  on  the  Ridley  Island  Energy  Export  Facility  ("REEF")  during  and 

subsequent to the fourth quarter of 2023. This included commencing site clearing work, including logging, clearing, 

and  drainage  work  that  will  further  solidify  the  project's  readiness  to  reaching  FID,  which  is  expected  during  the 

second quarter of 2024.

In December 2023, AltaGas commissioned the first of two new very large gas carriers ("VLGCs"), the Boreal Pioneer, 

which made its maiden voyage from Ferndale to Asia in early January 2024. The second VLGC, the Boreal Voyager, 

was commissioned in February 2024. These two seven-year time charters with optional extensions will reduce and 

de-risk shipping costs with materially all of AltaGas' expected Baltic freight exposure protected through time charters, 

financial hedges, and tolled volumes in 2024. 

▪ On October 20, 2023, Washington Gas executed a definitive agreement with Opal Fuels Inc. ("Opal Fuels") to support 

a renewable natural gas ("RNG") project at the Prince William County Landfill in Virginia. As part of the agreement, 

Washington Gas will become an offtake customer for RNG production and purchase key interconnect infrastructure 

for approximately US$25 million and continue to advance long-term climate goals. 

▪ On December 14, 2023, the Public Service Commission of Maryland ("PSC of MD") approved a US$10 million rate 

increase  with  a  9.5  percent  return  on  equity  and  52  percent  equity  thickness.  The  new  rates  became  effective 

immediately.

▪

On  December  22,  2023,  the  Public  Service  Commission  of  the  District  of  Columbia  ("PSC  of  DC")  approved  an 

increase  of  approximately  US$20  million  in  revenues,  net  of  approximately  US$5  million  of  costs  collected  through 

Washington  Gas'  40-year  accelerated  pipeline  replacement  program  ("PROJECTpipes")  surcharge. This  included  a 

9.65 percent return on equity and 52 percent equity thickness. The new rates went into effect January 19, 2024.

▪ On  December  5,  2023,  AltaGas'  Board  of  Directors  approved  a  6  percent  increase  to  its  annual  common  share 

dividends to $1.19 per common share annually ($0.2975 per common share quarterly). This change will be effective 

for the dividend that will be paid on March 29, 2024. 

▪ On  December  5,  2023, AltaGas  released  its  2023  ESG  Report,  highlighting  2022  data  for  key  topics  and  outlining 

progress towards the Company's sustainability goals within the areas of climate, diversity and inclusion, and safety.

AltaGas is pleased with the construction progress on MVP. The pipeline is now 99 percent complete and expected to 

be  placed  into  service  in  the  second  quarter  of  2024,  and  will  provide  critical  energy  security  to  customers  in  the 

Eastern U.S.  

AltaGas had a series of financings during the fourth quarter, including:

▪

2024 Outlook

In  2024,  AltaGas  expects  to  achieve  normalized  EBITDA  of  approximately  $1.675  to  $1.775  billion,  compared  to  actual 

normalized EBITDA of $1.58 billion in 2023, and normalized earnings per share of approximately $2.05 to $2.25 compared to 

actual  normalized  earnings  per  share  and  GAAP  net  income  per  share  of  $1.90  and  $2.27  in  2023.  For  the  year  ended 

December 31, 2023, income before income taxes and net income applicable to common shares were $912 million and $641 

million, respectively.

The Utilities segment is expected to contribute approximately 55 percent of normalized EBITDA in 2024, with year-over-year 

growth  driven  primarily  by  positive  contribution  from  the  continued  rate  base  growth  through  ongoing  capital  investments  in 

asset modernization programs on behalf of AltaGas' customers, the DC rate case, normal 2024 weather, and new customer 

growth, partially offset by the lost contribution from the Alaskan utilities due to the Alaska Utilities Disposition in the first quarter 

of  2023,  and  higher  operating  and  administrative  expenses  associated  with  a  higher  inflationary  and  cost  environment. The 

Midstream segment is expected to contribute approximately 45 percent of normalized EBITDA, with year-over-year expected 

growth driven primarily by contributions from the Pipestone Acquisition, strong expected global export volumes and margins, 

higher  utilization  at  the  Company's  Northeastern  B.C.  facilities,  and  the  absence  of  wildfire  impacts,  partially  offset  by  the 

absence  of  the  resolution  of  certain  commercial  disputes  in  2023,  and  lower  co-generation  revenue  at  the  Harmattan  gas 

processing facility and extraction plant ("Harmattan"). Normalized EBITDA from the Corporate/Other segment, which includes 

AltaGas'  remaining  power  assets,  is  expected  to  be  higher  in  2024  mainly  due  to  the  impact  of  higher  expected  financial 

performance at Blythe. 

The  expected  variance  in  normalized  earnings  per  share  from  $1.90  in  2023  to  approximately  $2.05  to  $2.25  in  2024  is 

expected to be primarily due to the same factors impacting normalized EBITDA and lower expected preferred share dividends, 

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

expense.

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

rate. 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.  For  further 

discussion of the risks impacting AltaGas please refer to the Risk Factors section of AltaGas' 2023 Annual Information Form, 

which is available on SEDAR+ at www.sedarplus.ca.

AltaGas continues to focus on de-risking its business and managing direct commodity price exposure to drive predictable and 

durable  results.  While  the  Company  does  have  exposure,  it  plans  to  maintain  an  active  hedging  program  that  proactively 

hedges commodity price and spread risk to mitigate the impact of fluctuations in margins and cash flows. For 2024, AltaGas 

has hedged:

▪

▪

Approximately  90  percent  of  AltaGas'  2024  expected  global  export  volumes  through  a  combination  of  tolls  and 

financial hedges with an average FEI to North American financial hedge price of approximately US$18/Bbl for non-

tolled propane and butane volumes.

Approximately  80 percent  of its 2024 expected frac exposed volumes hedged  at  approximately US$27/Bbl, prior  to 

transportation costs. 

▪ Materially  all  of AltaGas'  expected  Baltic  freight  exposure  is  protected  through  time  charters,  financial  hedges,  and 

tolled volumes in 2024.

Growth Capital

AltaGas  is  maintaining  a  disciplined,  equity  self-funded  capital  program,  and  currently  expects  to  deploy  approximately  $1.2 

billion  of  invested  capital  in  2024,  compared  to  actual  invested  capital  of  $946  million  in  2023.  The  Utilities  segment  is 

expected to account for approximately 58 percent of total 2024 capital expenditures, while the Midstream segment is expected 

to  account  for  approximately  36  percent,  and  the  Corporate/Other  segment  will  account  for  the  balance.  In  2024, AltaGas’ 

capital expenditures for the Utilities segment are expected to focus primarily on maintenance, safety, and reliability programs 

including  system  betterment,  asset  modernization  and  pipeline  replacement  programs,  and  new  customer  additions.  In  the 

Midstream  segment,  capital  expenditures  are  anticipated  to  primarily  relate  to  new  project  development,  maintenance  and 

administrative  capital,  optimization  of  existing  assets,  and  environmental  initiatives.  The  Corporation  continues  to  focus  on 

capital efficient organic growth and disciplined capital allocation while improving balance sheet strength and flexibility.

AltaGas' 2024 committed capital program is expected to be funded through internally-generated cash flow, opportunistic asset 

sales, and normal course borrowings on existing committed credit facilities.

Please refer to the Net Invested Capital and Non-GAAP Financial Measures sections of this MD&A for additional information

Pipestone  Phase  II  is  a  100  MMcf/d  sour  deep-cut  natural 
gas processing facility with 20,000 Bbls/d of liquids handling 
capabilities. The project reached a positive FID in December 
2023 and is 100 percent contracted under long-term take-or-
pay  agreements.  The  project  will  be  adjacent  to  Pipestone 
Phase I, which AltaGas acquired in December 2022, and will 
be constructed on a fixed price turnkey basis for the majority 
of  the  capital  costs.  The  project  will  begin  construction  in 
2024  and  when  complete,  will  deliver  critical  gas  processing 
and  liquids  handling  capacity  in  the  Pipestone  region  of 
Alberta,  which  is  one  of  the  fastest  growing  liquids-rich 
natural gas developments in Canada. 

REEF is a proposed large-scale LPG and bulk liquids export 
terminal with supporting marine infrastructure that is planned 
to  be  constructed  on  Ridley  Island,  British  Columbia.  The 
project 
is  being  developed  by  AltaGas  and  Vopak 
Development Canada Holdings Inc. ("Vopak") and is planned 
to be located adjacent to the partners' existing RIPET facility. 
Should REEF reach a positive FID, the project is planned to 
be  developed  and  brought  online  in  phases.  This  approach 
will provide the most capital efficient build out of the project, 
match  energy  export  supply  with 
throughput  capacity, 
mitigate the challenges that a large development project can 
have  on  the  local  community,  and  provide  local  construction 
and employment opportunities that would extend over longer 
time horizons. AltaGas will hold a 50 percent working interest 
in REEF and will be the project operator with Vopak holding 
the other 50 percent interest. If a positive FID is made, Phase 
1 is anticipated to begin construction in 2024 and will include 
construction of a new deep water marine jetty with significant 
capacity for potential future phases. During the fourth quarter 
of  2023,  site  clearing  work  including  logging,  clearing,  and 
draining  activities  commenced,  that  will  further  solidify  the 
project's readiness to reaching FID, which is expected during 
the second quarter of 2024.

into  precedent  agreements  with 
to 
collectively  provide  550,000  Dth  per  day  of  firm  capacity 
commitments  for  20-year  terms  with  two  potential  five-year

equity investment in the MVP Southgate project to a carrying 
value of $nil as a result of legal and regulatory challenges the 
project has encountered.

The  second  phase  of  Washington  Gas'  accelerated  pipe 
replacement program ("ARP") modernization in D.C. ended in 
December  2023.  On  December  22,  2022,  Washington  Gas 
filed an application with the PSC of DC for PROJECTpipes 3, 
seeking  approval  of  approximately  US$672  million  for  the 
five-year period from January 1, 2024 to December 31, 2028. 
On  November  6,  2023,  Washington  Gas  filed  a  request  to 
extend PROJECTpipes 2 through December 31, 2024, while 
the  PSC  of  DC  continues  to  evaluate  the  PROJECTpipes  3 
application. The Office of the People’s Counsel for the District 
of  Columbia 
request,  and 
Washington  Gas  responded.  On  December  20,  2023,  the 
PSC  of  DC  held  Washington  Gas'  extension  request  in 
abeyance  and  directed  the  filing  of  additional  information  to 
justify  the  extension.  On  January  4,  2024,  Washington  Gas 
filed  the  requested  information.  Other  parties  subsequently 
filed  comments  responding  to  Washington  Gas'  submission. 
On  February  23,  2024,  the  PSC  of  DC  granted  Washington 
Gas' request to extend PROJECTpipes 2 and the surcharge

The  second  phase  of  Washington  Gas'  ARP  modernization 
program  in  Maryland  ("STRIDE  2.0")  ended  in  December 
2023.  Beginning  in  March  2022,  the  PSC  of  MD  has  issued 
orders  reducing  the  Strategic  Infrastructure  Development 
Enhancement  Plan  (STRIDE)  surcharge  for  2022  and  2023 
by  14.7  percent  each  year.  Recovery  of  STRIDE 
expenditures not included in this surcharge will be requested 
through the normal rate-making process. On June 16, 2023, 
Washington Gas filed an application with the PSC of MD for 
the third phase of its ARP modernization  program ("STRIDE 
3"),  seeking  approval  for  approximately  US$495  million  of 
modernization  investments  on  behalf  of  customers  over  the 
five-year period from January 1, 2024 to December 31, 2028. 
On October 25, 2023, a public law judge issued a proposed 
order  to  approve  the  STRIDE  3  plan,  subject  to  a  reduced 
number  of  replacement  projects  equal  to  a  reduction  to  the 
five-year  budget  by  at  least  one  third.  On  November  13, 
2023, Washington Gas notified the PSC of MD that it accepts 
the  order.  Two  other  parties  [Maryland  Office  of  People's 
Counsel ("MD OPC") and Sierra Club] appealed, with Sierra 
Club  arguing  for  a  smaller ARP  program.  On  December  13, 
2023,  the  PSC  of  MD  affirmed  the  public  law  judge's 
proposed  order  in  part,  and  directed  Washington  Gas  to 
negotiate  the  terms  of  a  notice  to  be  sent  to  impacted 
customers.  On  January  10,  2024,  the  PSC  of  MD  issued  a 
memorandum explaining its December 13, 2023 decision. On 
February  9,  2024,  the  MD  OPC  filed  a  motion  for  rehearing 
with  the  PSC  of  MD.  Washington  Gas  filed  a  response  on

Utilities

Description of Assets

AltaGas  owns  and  operates  utilities  assets  that  store  and  deliver  natural  gas  to  residential,  commercial,  and  industrial  end-

users in Virginia, Maryland, Michigan, and the District of Columbia. Subsequent to the Alaska Utilities Disposition on March 1, 

2023,  AltaGas'  Utilities  provide  energy  to  approximately  1.6  million  customers  with  an  average  rate  base  of  approximately 

US$5.1 billion. 

The Utilities are underpinned by regulated returns and regulatory regimes that generally provide AltaGas with 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 

lower-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: 

Hampshire Gas, which provides regulated interstate natural gas storage to Washington Gas; 

▪ Washington Gas, which is a regulated gas utility that operates in Virginia, Maryland, and the District of Columbia;
▪
▪
▪ WGL's Retail Marketing business, which is an unregulated energy platform that sells power and natural gas directly 
to  residential,  commercial,  and  industrial  customers  in  Maryland,  Virginia,  Delaware,  Pennsylvania,  Ohio,  and  the 

SEMCO, which is a regulated gas utility that operates in Michigan; and

District of Columbia.

AltaGas Ltd. – 2023 MD&A and Financial Statements - 14

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  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  gas  utility  that  distributes  natural  gas  to  end  users  in  Virginia,  Maryland,  and  the  District  of 

Columbia. At the end of 2023, Washington Gas had approximately 1.2 million customers, of which approximately 94 percent 

were  residential  and  the  balance  were  commercial  and  industrial.  The  number  of  customers  at  Washington  Gas  increased 

approximately 1 percent in 2023. The average rate base for the year ended December 31, 2023 was approximately US$4.2 

billion. At the end of 2023, the approved regulated ROE for Washington Gas in its various jurisdictions ranged from 9.3 - 9.7 

percent based on an equity ratio ranging from 52.0 - 52.5 percent. 

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  utilizes  ARP  modernization  programs  across  all  three  of  its  operating  jurisdictions.  These  programs  are 

focused  on  reducing  risk  and  further  enhancing  the  safety  and  reliability  of  the  networks.  Each  regulatory  commission  with 

jurisdiction  over  Washington  Gas’  customer  rates  has ARPs  with  an  associated  surcharge  mechanism  to  recover  the  cost, 

including  providing  a  return  on  those  capital  investments.  In  contrast  to  the  traditional  rate-making  approach  to  capital 

AltaGas Ltd. – 2023 MD&A and Financial Statements - 15

investments, these ARP programs ensure that Washington Gas is receiving recovery for these investments as the programs 

are executed against over three to five-year approved increments. 

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

gas  unbundling. As  at  December  31,  2023,  approximately  13  percent  of  its  customers  have  chosen  to  purchase  gas  from 

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

of natural gas to firm customers, rather 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,  2023,  it  had  service  agreements  with  four  pipeline  companies  that  provided  firm  transportation  and  storage 

services with contract expiration dates ranging from 2024 to 2044. 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 available, when those assets are not required to serve 

utility  customers.  The  objective  of  this  program  is  to  derive  a  profit  from  excess  storage  and  transportation  capacity  that  is 

shared with its utility customers. These profits are earned by entering into commodity-related physical and financial contracts 

with third parties and the profits help reduce overall utility costs for Washington Gas' customers. 

Hampshire Gas

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 

Federal Energy Regulatory Commission ("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

SEMCO is a regulated gas utility that distributes natural gas to end users in Michigan's southern half of the Lower Peninsula 

and in the central, eastern, and western parts of the state's Upper Peninsula. At the end of 2023, SEMCO had approximately 

320,000  regulated  customers,  of  which  approximately  92  percent  were  residential,  and  the  balance  were  commercial  and 

industrial. In 2023, SEMCO experienced customer growth of approximately 1 percent reflecting growth in the franchise areas 

and customer conversions with the favourable price of natural gas compared to other heating sources. The average 2023 rate 

base  was  approximately  US$894  million.  In  2023,  the  approved  regulated  ROE  for  SEMCO  was  9.87  percent  with  an 

approved capital structure based on 45.86 percent equity, inclusive of the impact of deferred income tax. 

SEMCO is regulated by the Michigan Public Service Commission ("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 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. 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, an IRIP was approved in the 2019 rate case, 

pursuant  to  which  SEMCO  will  complete  certain  projects  totaling  US$55  million  to  improve  the  reliability  of  infrastructure. 

Similar to the MRP, any unspent IRIP capital is placed into a regulatory liability account to be addressed in the next general 

rate base case. At December 31, 2023, there was less than $1 million of underspent IRIP capital.  

AltaGas Ltd. – 2023 MD&A and Financial Statements - 16

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 March 2026 has been entered into with Shell Energy North America (US), L.P, which reduces 

credit requirements.

Capitalize on Opportunities

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 9 percent over the 

past  three  years  after  adjusting  for  the  impact  of  foreign  exchange  translation  and excluding  the  impact  of  asset  sales. The 

growth  in  rate  base  is  a  result  of  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  a  leading  North American  platform  that  connects  customers  and  markets.  From  wellhead  to 

tidewater, the Company is focused on providing its customers with safe and reliable service and connectivity that facilitates the 

best  outcomes  for  their  businesses.  This  includes  global  market  access  for  North  American  LPGs,  which  provides  North 

American producers and aggregators with attractive netbacks for propane and butane while delivering diversity of supply and 

supporting stronger energy security in Asia to AltaGas' downstream customers.

Throughout AltaGas' Midstream operations, the Company is playing a vital role within the larger energy ecosystem that keeps 

the global economy moving forward in a safe, reliable, and affordable manner.

AltaGas’  Midstream  platform  is  heavily  focused  on  the  Montney  and  Deep  Basin  resource  plays  and  centers  around  global 

exports, which is where the Company believes the market is headed for Canadian resource development over the long-term. 

AltaGas also operates a broader set of midstream infrastructure assets across the WCSB and select regions in the U.S., which 

are all focused on connecting customers and markets in the most efficient manner possible.

There  are  three  core  pillars  to  AltaGas’  Midstream  platform  that  are  integral  to  each  other  and  facilitate  the  Company’s 

wellhead to tidewater value chain. These include:

AltaGas Ltd. – 2023 MD&A and Financial Statements - 17

 
 
▪

▪

▪

Global Exports, which includes AltaGas’ two operational LPG export terminals where the Company has capacity to 

export up to 150,000 Bbl/d of propane and butane to key markets in Asia;

Natural Gas Gathering, Processing and Extraction, which includes 1.2 Bcf/d of extraction processing capacity and 

approximately  1.2  Bcf/d  of  raw  field  gas  processing  capacity,  which  is  heavily  focused  on  the  Montney  and  Deep 

Basin; and

Fractionation  and  Liquids  Handling,  which  includes  85  MBbl/d  of  fractionation  capacity  and  a  sizable  liquids 

handling footprint.

The  Midstream  segment  also  consists  of  natural  gas  and  NGL  marketing  business,  domestic  logistics,  trucking  and  rail 

terminals,  and  approximately  3.2  million  barrels  of  liquid  storage  capability  though  a  network  of  underground  salt  caverns 

through  the  Company’s  Strathcona  Storage  Joint  Venture  with  ATCO  Energy  Solutions  Ltd,  15  Bcf  of  natural  gas  storage 

through the recently acquired Dimsdale facility, as well as AltaGas’ 10 percent interest in MVP, which is nearing completion.

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  business  provides  market  connectivity  for  north American  LPGs  to  reach  global  downstream  markets 

and realize the strongest pricing. The business owns and operates two large-scale operational export terminals and has one 

AltaGas Ltd. – 2023 MD&A and Financial Statements - 18

proposed new export terminal that is currently undergoing FEED evaluation with expectations of reaching an FID in the second 

quarter of 2024.

The operational terminals include RIPET, which is located on Ridley Island in Northern B.C. and exclusively exports propane, 

and the Ferndale terminal, which is located in Washington State and exports propane and butane to key downstream markets. 

The two facilities have the combined capacity to export up to 150,000 Bbls/d of LPGs and are supported by 1.4 million barrels 

of onsite LPG storage capacity. Both of these facilities are capable of loading VLGCs, which provide the strongest economies 

of  scale  and  are  the  most  efficient,  safest,  and  lowest-carbon  solution  to  transporting  across  the  Pacific  Ocean.  VLGCs  are 

also the most in demand vessels from a destination perspective in key import markets, like Japan and South Korea.

REEF is a proposed large-scale LPG and bulk liquids export terminal with supporting marine infrastructure that is planned to 

be  constructed  on  Ridley  Island  in  Northern  B.C.  and  will  be  adjacent  to  the  current  RIPET  terminal.  The  project  is  being 

developed by AltaGas and Vopak and is proposed to have the capability to export propane and butane in the first phase of 

development,  with  bulk  liquids,  ethane  and  other  products  as  potential  next  phases  of  development. Should  REEF  reach  a 

positive FID, the project is planned to be developed and brought online in phases. This approach will provide the most capital 

efficient  build  out  of  the  project,  match  energy  export  supply  with  throughput  capacity,  mitigate  the  challenges  that  a  large 

development  project  can  have  on  the  local  community,  and  provide  local  construction  and  employment  opportunities  that 

would extend over longer time horizons. If a positive FID is made, Phase 1 is anticipated to begin construction in 2024 and will 

include  construction  of  a  new  deep  water  marine  jetty  with  significant  capacity  for  potential  future  phases.  During  the  fourth 

quarter of 2023, site clearing work, including logging, clearing, and draining activities commenced, which further solidifies the 

project's readiness to advance the project.

Natural Gas Gathering, Processing and Extraction

Gas  gathering  and  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'  gas  gathering,  processing,  and 

extraction facilities are as follows:

AltaGas also owns and operates the Pipestone II facility, for which a positive FID has been made. Pipestone Phase II is a fully 

permitted, shovel-ready expansion project that will provide an additional 100 MMcf/d of sour deep-cut natural gas processing 

capacity and an additional 20,000 Bbls/d of liquids handling capabilities. 

Fractionation and Liquids Handling

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 liquids 

handling  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'  liquids  handling  infrastructure  consists  of  NGL  pipelines,  treating,  storage,  truck,  and  rail  terminal  infrastructure 

centered around AltaGas’ key Midstream operating assets at RIPET, Ferndale, Harmattan and, in Northeast British Columbia 

("NEBC"),  Townsend  and  North  Pine.  AltaGas'  fractionation  and  liquids  handling  business  also  includes  terminals,  wellsite 

fluids and fuels, and trucking.

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.    

AltaGas' 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  AltaGas'  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. AltaGas 

supports  its  distribution  efforts  by  maintaining  an  extensive  leased  rail  fleet.  Leases  are  on  a  full-service  basis  and  are 

established on a staggered maturity schedule with multiple lessors to ensure railcar integrity and up-to-date DOT classification.

Pipeline Investments

AltaGas has a 10 percent equity interest in the MVP, which is an interstate natural gas pipeline system that spans more than 

300 miles from northwestern West Virginia to southern Virginia. The project is owned by a consortium with AltaGas owning a 

10 percent equity stake. The project is expected to provide up to 2.0 Bcf/d of firm transmission capacity to markets in the Mid- 

and South Atlantic regions of the United States and has throughput expansion opportunities.  AltaGas also owns a 5 percent 

equity stake in the MVP Southgate Project, which is an interstate natural gas pipeline that will extend MVP by approximately 

75  miles  from  Southern  Virginia  into  central  North  Carolina. The  targeted  in-service  date  for  MVP  is  the  second  quarter  of 

2024, and the completion date for MVP Southgate is June 2028. Please refer to the Growth Capital section of the MD&A for 

additional details on MVP and MVP Southgate. 

Harmattan Acid Gas Injection Well and Rolling Hills Carbon Capture Project 

AltaGas is nearing the completion of the Harmattan Acid Gas Injection well, which is a project that will be capable of capturing 

up to 60,000 tonnes/year of carbon emissions at the Company’s Harmattan gas plant. The project involves decommissioning 

Harmattan’s  existing  sulfur  plant,  which  significantly  reduces  the  facility’s  operational  complexity  and  extends  the  facility’s 

turnaround cycle from 4 years to 5 years, which is expected to result in ongoing cost savings. The acid gas injection well was 

placed in service in January 2024.

Rolling  Hills  is  a  prospective  open-access  carbon  hub  being  evaluated  by AltaGas  and  Whitecap  and  would  be  strategically 

located near AltaGas’ Harmattan gas plant and is surrounded by Whitecap’s extensive production and geological leadership in 

Central Alberta. The project is designed to include CO2 injection wells, carbon storage in underground reservoirs, and various 
intra-hub  pipelines. AltaGas  would  have  a  50  percent  interest  in  the  project  with  Whitecap  Resources  holding  the  other  50 

percent interest. The project has been awarded carbon sequestration hub evaluation rights with evaluation work progressing.

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 

export platform. New infrastructure consists of larger scale facilities supporting the vast reserves in North America and growing 

the  footprint  and  integration  of  AltaGas'  existing  assets.  While  providing  safe  and  reliable  service,  AltaGas  pursues 

opportunities in the Midstream segment to deliver value to its customers while enhancing long-term shareholder value.

Corporate/Other

Description of Assets

AltaGas'  Corporate/Other  activities  includes  all  non-operating  activities  that  support  AltaGas  and  are  not  specifically 

attributable  to  the  Utilities  and  Midstream  segments.  This  includes  the  last  remaining  assets  of  AltaGas'  former  Power 

segment, including the Blythe Energy Center, a natural gas-fired plant in California with 507 MW of generating capacity (the 

"Blythe Energy Center" or "Blythe").

Blythe  Energy  Center  is  a  gas-fired  power  generation  asset  that  serves  the  transmission  grid  operated  by  the  California 

Independent  System  Operator  ("CAISO")  to  cover  periods  of  high  demand  primarily  driven  by  the  Los Angeles  region.  The 

facility  is  directly  connected  to  an  El  Paso  Gas  Company  natural  gas  pipeline  for  its  primary  gas  supply  and  a  Southern 

California Gas Company pipeline as a secondary supply source, and interconnects to Southern California Edison ("SCE") and 
CAISO via a 67-mile transmission line also owned by Blythe Energy Inc., an indirect wholly-owned subsidiary of AltaGas. In 
February 2023, AltaGas reached an agreement with SCE for the purchase of resource adequacy attributes from Blythe for the 

period from January 1, 2024 through December 31, 2027. AltaGas believes this facility is an important asset for California to 

meet its ongoing power needs and ensuring the reliability of the power grid during peak demand periods.

(5) Weighted average.

Three Months Ended December 31

Normalized EBITDA for the fourth quarter of 2023 was $502 million, compared to $454 million for the same quarter in 2022. 

The largest positive impact was from the Midstream segment, followed by the Utilities and Corporate/Other segments. 

In the Midstream segment, normalized EBITDA was positively impacted by higher profitability from the global exports business, 

including  hedging  gains,  AFUDC  at  MVP  as  a  result  of  the  resumption  of  construction  activities  in  June  2023,  stronger 

marketing profitability due to the absence of the 2022 write down of natural gas storage inventory to its net realizable value, 

and  lower  operating  and  administrative  expenses  in  the  quarter.  These  factors  were  partially  offset  by  the  absence  of  the

favourable resolution of certain acquisition related commercial disputes and contingencies in the fourth quarter of 2022, lower 

profitability at the extraction facilities driven by lower frac spreads, third party pipeline restrictions, and lower power revenue at 

Harmattan primarily driven by lower power prices.

In  the  Utilities  segment,  factors  positively  impacting  normalized  EBITDA  included  higher  contribution  from  WGL's  retail 

marketing  business,  customer  growth,  higher  rate  base  from  ongoing  ARP  modernization  investments,  foreign  exchange 

hedge  gains,  contribution  from  Washington  Gas'  2022  Virginia  rate  case,  and  lower  operating  and  administrative  expenses. 

These factors were partially offset by the impact of the Alaska Utilities Disposition, decreased asset optimization activities at 

Washington Gas relative to the larger-than-normal contribution in the fourth quarter of 2022, and warmer weather in Michigan 

and the District of Columbia where the Utilities do not have weather normalization and decoupled rate structures. 

In the Corporate/Other segment, normalized EBITDA was positively impacted by lower personnel-related expenses and lower 

corporate operating and administrative expenses. 

For the three months ended December 31, 2023, the average Canadian/U.S. dollar exchange rate increased to 1.362 from an 

average of 1.358 in the same quarter of 2022, resulting in an increase in normalized EBITDA of less than $1 million. 

Income before income taxes for the fourth quarter of 2023 was $161 million, compared to $78 million for the same quarter in 

2022. The increase was mainly due to lower unrealized losses on risk management contracts, the same previously referenced 

factors  impacting  normalized  EBITDA,  and  the  absence  of  provisions  on  assets,  partially  offset  by  higher  foreign  exchange 

losses and costs related to the CEO transition and other restructuring initiatives that took place in 2023. Net income applicable 

to common shares for the fourth quarter of 2023 was $113 million ($0.40 per share), compared to $54 million ($0.19 per share) 

for  the  same  quarter  in  2022.  The  increase  was  primarily  due  to  the  same  previously  referenced  factors  impacting  income 

before income taxes, partially offset by higher income tax expense and the loss on the redemption of the Series E Preferred 

Shares on December 31, 2023. 

Normalized funds from operations for the fourth quarter of 2023 was $376 million ($1.33 per share), compared to $371 million 

($1.32  per  share)  for  the  same  quarter  in  2022.  The  increase  was  mainly  due  to  the  same  previously  referenced  factors 

impacting  normalized  EBITDA,  partially  offset  by  the  impact  of  non-cash  items  included  in  normalized  EBITDA,  higher 

normalized current income tax expense, and higher interest expense.

Cash from operations for the fourth quarter of 2023 was $154 million ($0.54 per share), compared to cash used by operations 

of $289 million ($1.02 per share) for the same quarter in 2022. The increase was mainly due to favourable variances in the net 

change in operating assets and liabilities, primarily as a result of fluctuations in commodity prices and sales volumes, partially 

offset by lower net income after taxes (after adjusting for non-cash items). Please refer to the Liquidity section of this MD&A for 

further details on the variance in cash from operations. 

In the fourth quarter of 2022, AltaGas recorded pre-tax provisions on assets of approximately $6 million ($5 million after-tax) 

primarily related to the abandoned Alton natural gas storage projects as a result of updated reclamation cost estimates. 

Operating and administrative expense for the fourth quarter of 2023 was $427 million, compared to $396 million for the same 

quarter in 2022. The increase was mainly due to the absence of acquisition related contingencies, partially offset by the impact 

of  the  Alaska  Utilities  Disposition.  Depreciation  and  amortization  expense  for  the  fourth  quarter  of  2023  was  $110  million, 

compared to $112 million for the same quarter in 2022. The decrease was due to the impact of the Alaska Utilities Disposition, 

partially offset by the impact of new assets placed in-service. Interest expense for the fourth quarter of 2023 was $101 million, 

compared to $99 million for the same quarter in 2022. The increase was due to $3 million of incremental hybrid interest costs 

compared  to  the  same  quarter  in  2022  due  to  hybrid  notes  replacing  preferred  shares.  Excluding  the  impact  of  shifting  the 

financing  costs  between  preferred  shares  and  hybrid  notes,  interest  costs  were  relatively  comparable.  For  the three  months 

AltaGas Ltd. – 2023 MD&A and Financial Statements - 25

 
ended  December  31,  2023, AltaGas  recorded  total  interest  expense  of  $11  million  on  the  subordinated  hybrid  notes,  which 

previously would have been captured in preferred share dividends.

AltaGas recorded income tax expense of $33 million for the fourth quarter of 2023 compared to $12 million in the same quarter 

in  2022.  The  increase  in  income  tax  expense  was  mainly  due  to  an  increase  in  income  before  income  taxes  in  the  fourth 

quarter of 2023 compared to the same quarter in 2022. 

Normalized net income was $214 million ($0.76 per share) for the fourth quarter of 2023, compared to $189 million ($0.67 per 

share) reported for the same quarter in 2022. The increase was mainly due to the same factors impacting normalized EBITDA, 

partially offset by higher foreign exchange losses and higher normalized income tax expense. Normalizing items in the fourth 
quarter of 2023 increased normalized net income by $101 million and included after-tax amounts related to unrealized losses 
on  risk  management  contracts,  CEO  transition  and  other  restructuring  costs,  transaction  costs  related  to  acquisitions  and 

dispositions,  unrealized  foreign  exchange  losses  on  intercompany  balances,  and  loss  on  redemption  of  preferred  shares. 
Normalizing  items  in  the  fourth  quarter  of  2022  increased  normalized  net  income  by  $135  million  and  included  after-tax 
amounts  related  to  transaction  costs  related  to  acquisitions  and  dispositions,  provisions  on  assets,  unrealized  foreign 

exchange losses on intercompany balances, and unrealized losses on risk management contracts. 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, 2023 was $1,575 million, compared to $1,537 million in 2022, with the 

largest positive impact coming from the Midstream segment. 

In the Midstream segment, normalized EBITDA was positively impacted by higher earnings from the export facilities, AFUDC at 

MVP, the absence of the 2022 write down of natural gas storage inventory to its net realizable value, the favourable resolution 

of certain acquisition related commercial disputes and contingencies, and other smaller factors. These were partially offset by 

the absence of turnaround recoveries in the third quarter of 2022, the impact of the sale of AltaGas' interest in the Aitken Creek 

processing facilities in the second quarter of 2022, lower inventory withdrawals, lower earnings at the extraction facilities driven 

by lower frac spreads, higher operating costs within the global export business, downtime from turnarounds at the extraction 

facilities in the third quarter of 2023, and lower marketing contribution.

In  the  Utilities  segment,  factors  positively  impacting  normalized  EBITDA  included  the  impact  of  a  higher  average  Canadian/

U.S. dollar exchange rate, contribution from the 2022 Virginia rate case, higher revenue from ARP modernization investment, 

the gain resulting from the partial debt defeasance associated with the Alaska Utilities Disposition in the first quarter of 2023 

(please refer to Note 15 of the Consolidated Financial Statements as at and for the year ended December 31, 2023 for further 

details), customer growth, and foreign exchange hedge gains. These factors were more than offset by the impact of the Alaska 

Utilities Disposition, decreased asset optimization activities at Washington Gas relative to the larger-than-normal contribution in 

2022, warmer weather in Michigan and the District of Columbia where the utilities do not have weather normalization and rate 

decoupling, higher operating and administrative expenses, and lower contributions from WGL's retail marketing business.

Factors  that  positively  impacted  the  Corporate/Other  segment  normalized  EBITDA  included  lower  corporate  operating  and 

administrative expenses and lower personnel related expenses, partially offset by lower contributions from Blythe. 

For the year ended December 31, 2023, the average Canadian/U.S. dollar exchange rate increased to 1.35 from an average 

of 1.30 in 2022, resulting in an increase in normalized EBITDA of approximately $34 million.

Income before income taxes for the year ended December 31, 2023 was $912 million, compared to $716 million in 2022. The 

increase was mainly due to higher pre-tax gains on dispositions of assets, including the gain on the Alaska Utilities Disposition 

AltaGas Ltd. – 2023 MD&A and Financial Statements - 26

 
and  additional  proceeds  received  due  to  contract  contingencies  on  the  sale  of  the  Goleta  energy  storage  development  in 

Goleta, California ("Goleta") that was divested in the first quarter of 2022, as well as the same previously referenced factors 

impacting  normalized  EBITDA,  and  the  absence  of  provisions  on  assets,  partially  offset  by  higher  interest  expense,  higher 

transaction  costs  related  to  acquisitions  and  dispositions,  higher  unrealized  losses  on  risk  management  contracts,  CEO 

transition  and  other  restructuring  costs  incurred  in  2023,  and  higher  foreign  exchange  losses.  Net  income  applicable  to 

common shares for the year ended December 31, 2023 was $641 million ($2.27 per share), compared to $399 million ($1.42 

per share) in 2022. The increase was mainly due to the same previously referenced factors impacting income before income 

taxes,  lower  loss  on  the  redemption  of  preferred  shares,  lower  net  income  applicable  to  non-controlling  interests,  and  lower 

preferred share dividends, partially offset by higher income tax expense. 

Normalized funds from operations for the year ended December 31, 2023 was $1,128 million ($4.00 per share), compared to 

$1,204 million ($4.28 per share) in 2022. The decrease was mainly due to higher interest expense and the impact of non-cash 

items included in normalized EBITDA, partially offset by the same factors impacting normalized EBITDA and lower normalized 

current income tax expense. 

Cash from operations for the year ended December 31, 2023 was $1,121 million ($3.98 per share), compared to $539 million 

($1.92  per  share)  in  2022. The  increase  was  mainly  due  to  favourable  variances  in  the  net  change  in  operating  assets  and 

liabilities, primarily as a result of fluctuations in commodity prices and sales volumes, partially offset by lower net income after 

taxes after adjusting for non-cash items. Please refer to the Liquidity section of this MD&A for further details on the variance in 

cash from operations. 

In 2023, AltaGas recorded pre-tax gains on dispositions of assets of approximately $319 million which was primarily comprised 

of the gain on the Alaska Utilities Disposition. Additional proceeds included the favourable settlement of contract contingencies 

related  to  the  sale  of  Goleta,  and  the  cash  proceeds  received  from  an  escrow  account  related  to  the  2019  disposition  of 

AltaGas'  interest  in  the  Central  Penn  pipeline  ("Central  Penn").  In  2022, AltaGas  recorded  a  pre-tax  gain  on  disposition  of 

assets of approximately $3 million. 

Operating and administrative expense for the year ended December 31, 2023 was $1,579 million, compared to $1,568 million 

in 2022. The increase was due to a number of factors, including higher operating and administrative expense at the Utilities, 

the  impact  of  the  higher  average  Canadian/U.S.  dollar  exchange  rate,  and  higher  operating  costs  within  the  global  exports 

business, partially offset by the impact of the Alaska Utilities Disposition, lower operating costs at the extraction facilities and 

trucking business, the favourable resolution of select commercial disputes and contingencies, lower corporate operating and 

administrative expenses, and lower expenses related to employee incentive plans. Depreciation and amortization expense for 

the year ended December 31, 2023 was $441 million, compared to $439 million in 2022. The increase was mainly due to new 

assets placed in-service, partially offset by the impact of the Alaska Utilities Disposition. Interest expense for the year ended 

December  31,  2023  was  $394  million,  compared  to  $330  million  in  2022.  The  increase  was  due  to  higher  average  interest 

rates, higher average debt balances, $15 million of incremental hybrid interest costs due to hybrid notes replacing preferred 
shares, and a higher average Canadian/U.S. dollar exchange rate. For the year ended December 31, 2023, AltaGas recorded 

total interest expense of $37 million on the subordinated hybrid notes, which previously would have been captured in preferred 

share dividends.

AltaGas  recorded  income  tax  expense  of  $223  million  for  the  year  ended  December  31,  2023  compared  to  $143  million  in 

2022. The  increase  in  tax  expense  was  mainly  due  to  higher  income  before  income  taxes  and  the  tax  impact  of  the Alaska 

Utilities  Disposition.  Current  tax  expense  of $43  million  was  recorded  for  the  year  ended  December  31,  2023,  compared  to 

current tax expense of $23 million in 2022. The increase in current tax expense was mainly due to the tax impact of the Alaska 

Utilities Disposition in the first quarter of 2023.

Normalized net income was $536 million ($1.90 per share) for the year ended December 31, 2023, compared to $544 million 

($1.94  per  share)  in  2022.  The  decrease  was  mainly  due  to  higher  interest  expense,  higher  foreign  exchange  losses,  and 

higher accretion expense, partially offset by the same previously referenced factors impacting normalized EBITDA, lower net 

income  applicable  to  non-controlling  interests,  lower  preferred  share  dividends,  and  lower  normalized  income  tax  expense. 

Normalizing  items  in  the  year  ended  December  31,  2023  reduced  normalized  net  income  by  $105  million  and  included 
after-tax amounts related to gains on the sale of assets, unrealized losses on risk management contracts, transaction costs 
related to acquisitions and dispositions, CEO transition and other restructuring costs, unrealized foreign exchange losses on 

intercompany  balances,  loss  on  the  redemption  of  preferred  shares,  and  wind-up  of  the  Canadian  defined  benefit  pension 

plan. Normalizing items in the year ended December 31, 2022 increased normalized net income by $145 million and included 
after-tax  amounts  related  to  gains  on  sale  of  assets,  transaction  costs  related  to  acquisitions  and  dispositions,  loss  on 
redemption  of  preferred  shares,  provisions  on  assets,  reversal  of  provisions  on  investments  accounted  for  by  the  equity 

method,  non-controlling  interest  portion  of  non-GAAP  adjustments,  unrealized  foreign  exchange  losses  on  intercompany 

balances, and unrealized losses on risk management contracts.

Non-GAAP Financial Measures

This  MD&A  contains  references  to  certain  financial  measures  used  by  AltaGas  that  do  not  have  a  standardized  meaning 

prescribed by GAAP and may not be comparable to similar measures presented by other entities. Readers are cautioned that 

these non-GAAP measures should not be construed as alternatives to other measures of financial performance calculated in 
accordance  with  GAAP.  The  non-GAAP  measures  and  their  reconciliation  to  GAAP  financial  measures  are  shown  below. 
These  non-GAAP  measures  provide  additional  information  that  management  of  AltaGas  ("Management")  believes  is 

meaningful in describing AltaGas' operational performance, liquidity and capacity to fund dividends, capital expenditures, and 
other investing activities. The specific rationale for, and incremental information associated with, each non-GAAP measure is 
discussed below.

References  to  normalized  EBITDA,  normalized  net  income,  normalized  funds  from  operations,  normalized  income  tax 

expense,  normalized  effective  income  tax  rate,  net  debt,  net  debt  to  total  capitalization,  invested  capital,  and  net  invested 

capital throughout this MD&A have the meanings as set out in this section.

Change in Composition of Non-GAAP Measures

In the fourth quarter of 2023, Management has changed the composition of certain of AltaGas' non-GAAP measures such that 

normalized  net  income  now  excludes  the  impact  of  unrealized  intercompany  foreign  exchange  gains  (losses)  resulting  from 

intercompany  balances  between  a  U.S.  subsidiary  and  a  Canadian  entity,  where  the  foreign  exchange  impact  in  the  U.S. 

subsidiary is recorded through gain (loss) on foreign currency translation in the Consolidated Statements of Comprehensive 

Income and the Canadian entity revaluation is recorded through the foreign exchange gain (loss) line item on the Consolidated 

Statements  of Income. This change was made as a result of Management's assessment that excluding these intercompany 

foreign  exchange  impacts  from  normalized  net  income  is  more  representative  of  the  Company's  ongoing  financial 

performance.  Prior  period  calculations  of  the  relevant  non-GAAP  measures  have  been  restated  to  reflect  this  change.  The 

following table summarizes the impact of this change on the periods presented in this MD&A:

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  income  before  income  taxes 
adjusted for pre-tax depreciation and amortization, and interest expense.

AltaGas presents normalized EBITDA as a supplemental measure. Normalized EBITDA is used by Management to enhance 

the understanding of AltaGas' earnings over periods, as well as for budgeting and compensation related purposes. The metric 

is frequently used by analysts and investors in the evaluation of entities within the industry as it excludes items that can vary 

substantially  between  entities  depending  on  the  accounting  policies  chosen,  the  book  value  of  assets,  and  the  capital 

structure.

losses (gains) on intercompany balances between Canadian and U.S. entities. The amounts presented in this table reflect the restated figures to align with 
the revised policy. 

The  above  table  provides  a  reconciliation  of normalized  income  tax  expense  from  the  GAAP  financial  measure,  income  tax 

expense.  The  reconciling  items  are  comprised  of  the  income  tax  impacts  of  normalizing  items  present  in  the  calculation  of

reconciliation above.

Normalized income tax expense 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, plus current and long-term portions of long-term 

debt,  and  subordinated  hybrid  notes,  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

AFUDC is the amount that a rate-regulated enterprise is allowed to recover for its cost of financing assets under construction and is included in the "property,

(4) Relates to escrow account proceeds received from AltaGas' previous investment in Central Penn. Upon close of the sale in 2019, various escrow accounts 

(5)

were established to provide the purchaser a form of recourse for the settlement of indemnification obligations. 
In the fourth quarter of 2023, AltaGas changed its non-GAAP policy to exclude cash paid for business acquisitions and for the purchase of remaining non-
controlling interest in a subsidiary from invested capital. Prior periods have been restated to reflect this change. 

Invested  capital  is  a  measure  of AltaGas'  use  of  funds  for  capital  expenditure  activities.  It  includes  expenditures  relating  to 

property, plant, and equipment and intangible assets, capital contributed to long term investments, and contributions from non-

controlling interests. Net invested capital is invested capital presented net of cash paid for business acquisitions, cash paid for 

the  purchase  of  remaining  non-controlling  interest  in  a  subsidiary,  and  proceeds  from  disposals  of  assets  and  equity 

investments  in  the  period.  Net  invested  capital  is  calculated  based  on  the  investing  activities  section  in  the  Consolidated 

Statements  of  Cash  Flows,  adjusted  for  items  such  as  non-cash  capital  expenditures, AFUDC,  and  contributions  from  non-

controlling interests. Invested capital and net invested capital are used by Management, investors, and analysts to enhance 

the understanding of AltaGas' capital expenditures from period to period and provide additional detail on the Company's use of 

capital.

As noted previously in this MD&A, in the fourth quarter of 2023, AltaGas changed its non-GAAP policy to exclude the impact of unrealized foreign exchange 
losses (gains) on intercompany balances between Canadian and U.S. entities. The amounts presented in this table reflect the restated figures to align with 
the revised policy. 
The  portion  of  non-GAAP  adjustments  applicable  to  non-controlling  interests  are  excluded  in  the  computation  of  normalized  net  income  to  ensure 
consistency of normalizations applied to controlling and non-controlling interests. These amounts are included in the “net income applicable to non-controlling

Calculation of Normalized Effective Income Tax Rate 

The  below  table  provides  a  calculation  of  normalized  effective  income  tax  rate  from normalized  net  income  and  normalized 

income tax expense. Both of these non-GAAP measures have been previously reconciled to the relevant GAAP measures in 

the  section  above.  This  supplemental  calculation  is  provided  as  additional  information  to  assist  analysts  and  investors  in 

comparing normalized income tax expense to normalized net income and is not intended as a substitute for the reconciliations 

to the nearest comparable GAAP measures. Readers should not place undue reliance on this supplemental calculation.

Bcf is one billion cubic feet.  
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, during the prior 10 years for ENSTAR, and during the prior 30 years 
for  Washington  Gas. The  degree  day  variance  from  normal  for  ENSTAR  is  for  the  period  prior  to  the  close  of  the Alaska  Utilities  Disposition  on  March  1, 
2023.  
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.

During the fourth quarter of 2023, AltaGas’ Utilities segment experienced warmer weather at SEMCO and warmer weather at 

Washington Gas compared to the same quarter of 2022.

For the year ended December 31, 2023, AltaGas' Utilities segment experienced warmer weather at SEMCO, warmer weather 

at ENSTAR prior to the close of the Alaska Utilities Disposition, and warmer weather at Washington Gas compared to 2022.  

Service sites at December 31, 2023 decreased by approximately 144,000 sites compared to December 31, 2022 due to the 

impact  of  the  close  of  the  Alaska  Utilities  Disposition  on  March  1,  2023,  which  was  partially  offset  by  continued  customer 

additions across the remaining jurisdictions.

In the fourth quarter of 2023, U.S. retail gas sales volumes were 16,863 Mmcf, compared to 18,064 Mmcf in the same quarter 

of 2022. The decrease was primarily due to a decrease in commercial customers served by the business and warmer weather 

in the fourth quarter of 2023 compared to the same quarter of 2022. In the fourth quarter of 2023, U.S. retail electricity sales 

volumes  were  3,518  GWh  compared  to  3,328  GWh  in  the  same  quarter  of  2022.  The  increase  was  primarily  due  to  an

increase  in  commercial  customers  served  by  the  business,  partially  offset  by  warmer  weather  in  the  fourth  quarter  of 2023 

compared to the same quarter of 2022.

For the year ended December 31, 2023, U.S. retail gas sales volumes were 56,438 Mmcf, compared to 59,302 Mmcf in the 

same period in 2022. The decrease was primarily due to significantly warmer weather in the year ended December 31, 2023 

compared to 2022. For the year ended December 31, 2023, U.S. retail electricity sales volumes were 14,339 GWh compared 

to  13,217  GWh  in  the  same  period  in  2022. The  slight  increase  was  primarily  due  to  an  increase  in  commercial  customers 

served by the business.

Three Months Ended December 31

The Utilities segment reported normalized EBITDA of $311 million in the fourth quarter of 2023, compared to $294 million in 

the same quarter in 2022. The increase in normalized EBITDA was mainly due to higher gas and power margins from WGL's 

retail  marketing  business,  customer  growth,  higher  revenue  from  accelerated  pipe  replacement  program  spend,  foreign 

exchange hedge gains, the impact of Washington Gas' Virginia rate case, and lower operating and administrative expenses. 

These factors were partially offset by the impact of the Alaska Utilities Disposition in the first quarter of 2023, decreased asset 

optimization  activities  at  Washington  Gas  relative  to  the  larger-than-normal  contribution  in  the  fourth  quarter  of  2022,  and 

warmer weather in Michigan and the District of Columbia where the Utilities do not have weather normalization. 

The Utilities segment income before income taxes was $207 million in the fourth quarter of 2023, compared to $80 million in 

the same quarter in 2022. The increase was mainly due to lower unrealized losses on risk management contracts, the same 

previously referenced factors impacting normalized EBITDA, and lower depreciation expense, partially offset by costs related 

to restructuring initiatives. 

Year Ended December 31  

The Utilities segment reported normalized EBITDA of $886 million in the year ended December 31, 2023, compared to $933 

million  in  2022.  The  decrease  in  normalized  EBITDA  was  mainly  due  to  the  impact  of  the  Alaska  Utilities  Disposition, 

decreased  asset  optimization  activities  at  Washington  Gas  as  a  result  of  lower  margins  relative  to  larger-than-normal 

contributions  in  2022,  warmer  weather  in  Michigan  and  the  District  of  Columbia  where  the  Utilities  do  not  have  weather 

normalization,  higher  operating  and  administrative  expenses,  and  lower  contributions  from  WGL's  retail  marketing  business. 

These factors were partially offset by an impact of approximately $35 million due to the change in foreign exchange rates, the 

impact  of  Washington  Gas'  2022  Virginia  rate  case,  higher  revenue  from  accelerated  pipe  replacement  program  spend,  the 

gain  resulting  in  the  partial  debt  defeasance  associated  with  the  Alaska  Utilities  Disposition  in  the  first  quarter  of  2023, 

customer growth, and foreign exchange hedge gains. 

The Utilities segment income before income taxes was $886 million in the year ended December 31, 2023, compared to $548 

million in 2022. The increase was mainly due to the to the gain on the Alaska Utilities Disposition and higher unrealized gains 

on risk management contracts, partially offset by the same previously referenced factors impacting normalized EBITDA, higher 

transaction costs related to acquisitions and dispositions, and costs related to restructuring initiatives.

In 2023, the Utilities segment recognized a pre-tax gain on disposition of assets of approximately $304 million due to the gain 

on the Alaska Utilities Disposition.

Other Regulatory Updates

Merger Commitments - District of Columbia

On August 9, 2023, the PSC of DC determined that AltaGas had failed to fulfill Term No. 5 Commitment of the PSC of DC’s 

merger approval order related to the June 2018 merger of AltaGas, WGL, and Washington Gas. On reconsideration, the PSC 

of DC confirmed, in relevant part, that it had credited AltaGas with causing the development of 2.4 MW of Tier one renewable 

resources  by  the  July  6,  2023  deadline,  and  that  the  Company  had  breached  its  Term  No.  5  Commitment  only  for  the 

remaining 7.6 MW. As directed by the PSC of DC, AltaGas, the District of Columbia Government ("DCG"), and the District of 

Columbia Office of People’s Counsel ("DC OPC") conducted negotiations in good faith to reach agreement on a penalty. On 

November 14, 2023, DCG reported that DCG and AltaGas believed that further negotiations would be fruitless. In a November 

21,  2023  motion,  AltaGas  confirmed  that  it  will  specifically  perform  its  Term  No.  5  obligations  by  continuing  to  cause  the 

development of the remaining 7.6 MW of solar renewable energy. AltaGas also proposed a penalty of approximately US$0.5 

million if the Company fulfills the balance of its renewable development obligation before the end of 2024, or US$0.6 million if 

the balance is not completed until after the end of 2024. On December 19, 2023, DCG proposed that AltaGas pay a penalty of 

AltaGas Ltd. – 2023 MD&A and Financial Statements - 39

approximately US$8 million. OPC proposed a penalty not less than DCG’s proposed penalty, to be paid before September 30, 

2024.  Management  believes  that  the  likelihood  of  a  civil  penalty  is  probable  however,  is  unable  to  estimate  the  maximum 

possible penalty.

Prince William County Biogas Pipeline

On  December  4,  2023,  Washington  Gas  filed  an  application  with  the  SCC  of  VA  seeking  approval  for  a  biogas  supply 

investment  plan  and  rate  adjustment  clause.  Washington  Gas  seeks  approval  to  purchase,  own,  operate,  and  maintain  an 

eight-mile  pipeline,  associated  interconnection  facilities  and  other  necessary  equipment  to  transport  RNG  from  a  biogas 

production facility located at the Prince William County Landfill. Washington Gas also proposes to purchase a portion of the 

facilities  output,  a  subset  of  which  will  be  accompanied  by  marketable  environmental  attributes.  Washington  Gas  is  seeking 

recovery of the project costs and RNG costs through a RNG rider. Evidentiary hearing is set for March 19, 2024 and a decision 

is expected around early June 2024.

SEMCO Energy Waste Reduction Program ("EWRP")

On June 30, 2023, SEMCO submitted its 2024-2025 EWRP seeking approval to spend approximately US$35 million on energy 

waste  reduction  over  2024  and  2025.  SEMCO  reached  an  in-principle  settlement  agreement  with  the  MPSC  staff  and  the 

Michigan Department of Attorney General. The MPSC formally approved the settlement agreement on December 21, 2023. 

EmPOWER Maryland Plan

Effective January 1, 2024, the PSC of MD approved Washington Gas’ three-year plan modifying and expanding the existing 

portfolio  of  programs  for  residential,  commercial,  industrial,  and  low-income  customers  with  a  total  three-year  budget  of 

approximately  US$64  million.  The  approved  EmPOWER  Plan  also  includes  a  new  Demand  Response  program  for  eligible 

residential customers and a pilot to test and monitor Energy Management Systems for commercial buildings with centralized 

boiler heating systems.

LPG volumes exported to Asia from RIPET and Ferndale for the three months ended December 31, 2023 averaged 90,996 

Bbls/d  compared  to  97,152  Bbls/d  for  the  same  period  in  2022. There  were  15  full  shipments  and  1  partial  shipment in  the 

fourth quarter of 2023, compared to 16 full shipments in the same period in 2022. Lower export volumes were primarily the 

result of logistical constraints and the timing of ship loadings around quarter end, partially offset by higher available supply.

LPG  volumes  exported  to Asia  from  RIPET  and  Ferndale  for  the year  ended  December  31,  2023  averaged  106,071  Bbls/d 

compared to 101,654 Bbls/d for the same period in 2022. There were 71 full shipments and 1 partial shipment during the year 

ended December 31, 2023 compared to 68 shipments in the same period of 2022. The partially loaded vessels are a function 

of  revenue  recognition  taking  place  at  the  point  of  ship  loading  and  select  loadings  taking  place  over  quarter-ends.  Higher 

export volumes and shipments were primarily the result of increased offtake demand, higher available supply, and improved 

logistics.

Inlet gas processing volumes for the fourth quarter of 2023 increased by 38 Mmcf/d compared to the same quarter in 2022. 

Higher inlet gas processing volumes in the fourth quarter of 2023 were primarily the result of higher producer volumes at the 

Townsend complex and higher volumes at the Harmattan raw gas and co-stream facilities, partially offset by lower volumes at 

the Edmonton ethane extraction plant ("EEEP") due to the September turnaround, which extended into the fourth quarter of 

2023  and  third  party  pipeline  restrictions,  as  well  as  lower  volumes  at  the  Younger  extraction  plant  ("Younger")  due  to  the 

extension of a plant turnaround in the area.

Inlet gas processing volumes for the year ended December 31, 2023 increased by 35 Mmcf/d compared to the same period in 

2022. Higher inlet gas processing volumes in the year ended December 31, 2023 were primarily the result of higher producer 

volumes at the Townsend complex, higher volumes at the Harmattan raw gas and co-stream facilities, and higher frac exposed 

volumes, partially offset by the impact of the Aitken Creek sale in the second quarter of 2022, and lower volumes at EEEP due 

to the turnaround in September 2023 which extended into the fourth quarter of 2023, and third party pipeline restrictions.

Average  ethane  volumes  for  the  fourth  quarter  of  2023  increased  by  1,932  Bbls/d,  while  average  NGL  production  volumes 

increased by 1,356 Bbls/d compared to the same quarter in 2022. Higher ethane volumes were primarily a result of higher co-

stream  inlet  volumes  and  higher  raw  gas  production  at  Harmattan,  partially  offset  by  lower  volumes  at  EEEP  due  to  the 

extension of the plant turnaround and lower volumes at PEEP due to higher reinjection rates. Higher extracted NGL volumes 

were due to higher raw gas inlet volumes at the Townsend facilities due to higher demand from third party customers.

Average ethane volumes for the year ended December 31, 2023 increased by 1,717 Bbls/d compared to 2022, while average 

extracted NGL volumes increased by 1,516 Bbls/d compared to the same period in 2022. Higher ethane volumes were a result 

of higher co-stream inlet volumes and higher raw gas production at Harmattan, as well as higher volumes at the Joffre ethane 

extraction plant ("JEEP") due to the absence of a turnaround in the third quarter of 2022, partially offset by lower volumes at 

EEEP due to the turnaround in September 2023 and higher reinjection rates at PEEP. Higher extracted NGL volumes were a 

result  of  increased  production  at  the  Townsend  facilities  due  to  higher  demand  from  third  party  customers  and  higher 

production  at  Harmattan  due  to  the  absence  of  a  turnaround  in  the  second  quarter  of  2022,  partially  offset  by  a  third  party 

pipeline outage which resulted in the re-injection of NGL volumes at Gordondale in the first quarter of 2023.

Fractionation volumes for the fourth quarter of 2023 increased by 1,492 compared to the same quarter in 2022. The increase 

was due to higher Harmattan trucked-in NGL mix and raw gas volumes as a result of plant turnarounds in the area increasing 

spot  volumes  and  additional  volumes  resulting  from  increased  customer  production,  higher  fractionation  volumes  at  the 

Younger facility due to additional volumes sold during the turnaround extension, and higher North Pine volumes and utilization.

Fractionation  volumes  for  the  year  ended  December  31,  2023  increased  by  5,143  Bbls/d  compared  to  the  same  period  in 

2022.  Higher  fractionation  volumes  were  a  result  of  higher  North  Pine  volumes  and  utilization,  higher  Harmattan  trucked-in 

NGL mix and raw gas volumes as a result of plant turnarounds in the area increasing spot volumes and additional volumes 

resulting  from  increased  customer  production,  and  higher  fractionation  volumes  at  the  Younger  facility  due  to  additional 

volumes sold during the turnaround extension, partially offset by the impact of the wildfires at the NEBC facilities in the second 

quarter of 2023.

Three Months Ended December 31 

The Midstream segment reported normalized EBITDA of $182 million in the fourth quarter of 2023, compared to $163 million in 

the  same  quarter  in  2022.  The  increase  in  normalized  EBITDA  in  the  fourth  quarter  of  2023  was  mainly  due  to  strong 

performance from the global exports business as a result of higher LPG margins (inclusive of hedges), partially offset by lower 

merchant  volumes,  as  well  as AFUDC  at  MVP  as  a  result  of  the  resumption  of  construction  activities  in  June  2023,  higher 

marketing  volumes  and  margins  due  to  the  absence  of  the  2022  write  down  of  natural  gas  storage  inventory  to  its  net 

realizable value, and lower operating expenses at the processing and trucking facilities. The increase in normalized EBITDA 

was  partially  offset  by  the  absence  of  the  favourable  resolution  of  certain  acquisition  related  commercial  disputes  and 

contingencies in the fourth quarter of 2022, lower earnings at the extraction facilities driven by lower frac spreads and volumes 

due  to  third  party  pipeline  restrictions,  lower  power  revenue  at  Harmattan  primarily  driven  by  lower  power  prices,  and  lower 

crude marketing margins.

Income before income taxes in the Midstream segment was $79 million in the fourth quarter of 2023, compared to $113 million 

in  the  same  quarter  in  2022. The  decrease  was  mainly  due  to  higher  unrealized  losses  on  risk  management  contracts  and 

higher depreciation expense, partially offset by the same previously referenced factors impacting normalized EBITDA and the 

absence of provisions on assets.

In the fourth quarter of 2022, the Midstream segment recognized a pre-tax provision on assets of approximately $6 million ($5 

million after-tax) primarily related to the abandoned Alton natural gas storage project.

AltaGas Ltd. – 2023 MD&A and Financial Statements - 42

Year Ended December 31 

The  Midstream  segment  reported  normalized  EBITDA  of  $684  million  in  the  year  ended  December  31,  2023,  compared  to 

$607 million in 2022. There were several positive and negative contributors underpinning the year-over-year variance. Positive 

factors included strong performance from the global exports business as a result of higher LPG margins (inclusive of hedges) 

and tolling volume growth, as well as AFUDC at MVP as a result of the resumption of construction activities in June 2023, the 

absence of the 2022 write down of natural gas inventory to its net realizable value, resolution of certain commercial disputes 

and contingencies, stronger performance at Harmattan, and cost management across a number of businesses. These were 

partially offset by the absence of turnaround recoveries in the third quarter of 2022, the impact of the sale of AltaGas' interest 

in  the Aitken  Creek  processing  facilities  in  the  second  quarter  of  2022,  lower  inventory  withdrawals,  lower  earnings  at  the 

extraction  facilities  driven  by  lower  frac  spreads,  lower  marketing  performance,  and  lower  power  revenue  at  Harmattan 

primarily  due  to  lower  power  prices.  Other  factors  negatively  impacting  normalized  EBITDA  include  the  impact  of  the 

turnarounds at the extraction facilities in the third quarter of 2023 and the wildfires at NEBC facilities in the second quarter of 

2023, the latter of which included a 12.5 day force majeure. 

Income before income taxes in the Midstream segment was $460 million in the year ended December 31, 2023, compared to 

$526  million  in  2022.  The  decrease  was  mainly  due  to  higher  unrealized  losses  on  risk  management  contracts,  higher 

depreciation  expense,  and  higher  transaction  costs  related  to  acquisitions  and  dispositions,  partially  offset  by  the  same 

previously referenced factors impacting normalized EBITDA and the absence of provision on assets.

Corporate/Other  

Three Months Ended December 31 

In the Corporate/Other segment, normalized EBITDA for the fourth quarter of 2023 was $9 million, compared to a loss of $3 

million  in  the  same  quarter  in  2022.  The  increase  in  normalized  EBITDA  was  mainly  due  to  lower  expenses  related  to 

employee incentive plans and lower corporate operating and administrative expenses. 

Loss before income taxes in the Corporate/Other segment was $125 million in the fourth quarter of 2023, compared to $115 

million in the same quarter in 2022. The higher loss was mainly due to higher foreign exchange losses and costs related to the 

CEO  transition  and  other  restructuring  initiatives,  partially  offset  by  the  same  previously  referenced  factors  impacting 

normalized EBITDA and lower unrealized losses on risk management contracts.

Year Ended December 31

In the Corporate/Other segment, normalized EBITDA for the year ended December 31, 2023 was $5 million, compared to a 

loss of $3 million in 2022. The increase in normalized EBITDA was mainly due to lower corporate operating and administrative 

expenses and lower expenses related to employee incentive plans, partially offset by a lower contribution from Blythe.  

Loss before income taxes in the Corporate/Other segment was $434 million in the year ended December 31, 2023, compared 

to $358 million in 2022. The higher loss was mainly due to higher interest expense, costs related to the CEO transition and 

other  restructuring  initiatives,  higher  foreign  exchange  losses,  and  higher  transaction  costs  on  acquisitions  and  dispositions, 

partially offset by higher unrealized gains on risk management contracts, the same factors impacting normalized EBITDA, and 

additional proceeds received due to contract contingencies on the sale of Goleta in the first quarter of 2022.  

In 2023, the Corporate/Other segment recognized an additional pre-tax gain of approximately $11 million on the sale of Goleta 

in 2022 as a result of a payment received in the first quarter of 2023 for the favourable settlement of outstanding contingencies 

based  on  contract  outcomes.  In  2022,  the  Corporate/Other  segment  recognized  a  pre-tax  gain  on  disposition  of  assets  of 

approximately  $5  million  which  was  comprised  of  a  pre-tax  gain  of  $7  million  on  the  previously  mentioned  sale  of  Goleta, 

partially offset by a pre-tax loss of $2 million on the sale of a power plant in Brush, Colorado.

During the fourth quarter of 2023, AltaGas’ invested capital was $290 million, compared to $326 million in the same quarter in 

2022. The decrease in invested capital was primarily due to lower additions to property, plant, and equipment as a result of 

lower spend primarily on system betterment, new business, and general plant programs at Washington Gas, partially offset by

higher maintenance capital in the Midstream segment. In the fourth quarter of 2023, acquisitions related to the cash paid for 

the Pipestone Acquisition. 

The  invested  capital  in  the  fourth  quarter  of  2023  included  maintenance  capital  of  $31  million  (2022  -  $18  million)  in  the 
Midstream  segment  and  $1  million  (2022  -  less  than  $1  million)  related  to  remaining  power  assets  in  the  Corporate/Other 
segment. The increase in Midstream maintenance capital in the fourth quarter of 2023 primarily related to routine maintenance 

expenditures at the Younger, Harmattan, and Sarnia facilities, as well as turnaround expenditures at the EEEP and Ferndale 

facilities.

During the fourth quarter of 2023, AltaGas’ cash flow from investing activities was an outflow of $594 million, compared to $336

In the fourth quarter of 2023, AltaGas changed its non-GAAP policy to exclude cash paid for business acquisitions and for the purchase of remaining non-
controlling interest in a subsidiary from invested capital. Prior periods have been restated to reflect this change. 

During the year ended December 31, 2023, AltaGas’ invested capital was $946 million, compared to $948 million in 2022. The 

slight decrease in invested capital was primarily due to the lower spend on system betterment and new business programs in 

the  Utility  segment,  the  impact  of  the Alaska  Utilities  Disposition,  and  lower  maintenance  capital  in  both  the  Midstream  and 

Corporate/Other segments. The decrease was partially offset by higher spend on accelerated pipe replacement programs at 

Washington Gas, the impact of the higher average Canadian/U.S. dollar exchange rate, higher spend on the Harmattan acid

gas  injection  well,  and  higher  growth  capital  spend  in  the  Midstream  segment  primarily  related  to  Pipestone  Phase  ll,  new 

business development, and various optimization projects.

In  2023,  acquisitions  related  to  the  cash  paid  for  the  Pipestone Acquisition,  while  asset  dispositions  primarily  related  to  the 

Alaska Utilities Disposition and additional proceeds received for the favourable settlement of outstanding contingencies on the 

sale  of  Goleta  in  the  first  quarter  of  2022.  In  2022,  acquisitions  related  to  cash  paid  to  purchase  the  remaining  equity 

ownership of Petrogas, while asset dispositions primarily related to proceeds received from the sale of AltaGas' interest in the 

Aitken Creek processing facilities, a power plant in Brush, Colorado, and the previously mentioned sale of Goleta.

The invested capital for the year ended December 31, 2023 included maintenance capital of $53 million (2022 - $66 million) in 
the Midstream segment and $4 million (2022 - $8 million) related to remaining power assets in the Corporate/Other segment. 
The  decrease  in  maintenance  capital  for  the  Midstream  segment  was  primarily  due  to  lower  turnaround  spend  while  the 

decrease in maintenance capital for the Corporate/Other segment was primarily due to lower maintenance costs at Blythe. 

During  the  year  ended  December  31,  2023,  AltaGas’  cash  flow  from  investing  activities  was  an  outflow  of  $199  million, 

compared to $997 million in 2022. Please refer to the Non-GAAP Financial Measures and Liquidity sections of this MD&A for 

further information on AltaGas' cash flow from investing activities. 

Risk Management 

AltaGas  is  subject  to  a  variety  of  risks  which  could  have  a  material  impact  on  the  financial  results  and  operations  of  the 

Company.  Shareholders  and  prospective  investors  should  carefully  evaluate  risk  factors  noted  by  the  Company  before 

investing  in  the  Company’s  securities,  as  each  of  these  risks  may  negatively  affect  the  trading  price  of  the  Company’s 

securities, the amount of dividends paid to shareholders and the ability of the Company to fund its debt obligations, including 

debt obligations under its outstanding notes and any other debt securities that the Company may issue from time to time. For 

discussion of the risks and trends that could materially affect the Company’s performance please refer to AltaGas' 2023 Annual 

Information Form, which is available on SEDAR+ at www.sedarplus.ca.

Risk Management Contracts

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.  These  contracts  do  not 

eliminate AltaGas' exposure to risk associated with fluctuations in commodity prices or foreign exchange rates. 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,  2023  and 

December 31, 2022, the fair values of the Corporation’s derivatives were as follows:

AltaGas strives to continuously and systematically de-risk the business in order to drive predictable and durable returns and 

maximize  long-term  value  for  stakeholders.  For  Midstream,  this  includes  striving  to  match  financial  hedges  with  physical 

volumes, and for Utilities, this includes purchasing physical gas throughout the year to help shield customers from major cost 

spikes  during  peak  winter  demand.  AltaGas  may  also  enter  into  foreign  exchange  forward  derivatives  to  manage  the  risk 

associated with variations in foreign exchange rates.

Commodity Price Contracts 

The  Corporation  executes  natural  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 on published sources for the relevant period. 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,  2023  was  approximately  $22/Bbl 

(2022  –  $32/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, 2023 

was approximately $24/Bbl inclusive of basis differentials (2022 - $26/Bbl). 

AltaGas continues to focus on de-risking its business and managing direct commodity price exposure to drive predictable and 

durable  results.  While  the  Company  does  have  exposure,  it  plans  to  maintain  an  active  hedging  program  that  proactively 

hedges commodity price and spread risk to mitigate the impact of fluctuations in margins and cash flows. For 2024, AltaGas 

has hedged:

▪

▪

Approximately  90  percent  of  AltaGas'  2024  expected  global  export  volumes  through  a  combination  of  tolls  and 

financial hedges with an average FEI to North American financial hedge price of approximately US$18/Bbl for non-

tolled propane and butane volumes.

Approximately 80 percent  of its 2024 expected  frac exposed  volumes  hedged  at  approximately US$27/Bbl, prior  to 

transportation costs. 

• Materially  all  of AltaGas'  expected  Baltic  freight  exposure  is  protected  through  time  charters,  financial  hedges,  and 

tolled volumes in 2024.

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. 

AltaGas Ltd. – 2023 MD&A and Financial Statements - 47

 
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.  To  serve  retail  customers,  WGL  Energy  Services 

enters into both physical and financial contracts for the purchase and sale of electricity and natural gas. Beginning in 2023, 

WGL Energy Services also began purchasing natural gas indexed to NYMEX Henry Hub to be sold to third party customers. 

WGL  Energy  Services'  risk  management  objective  and  strategy  is  to  protect  earnings  against  the  risk  of  price  fluctuations 

associated with forecasted NYMEX Henry Hub purchases through the use of the NYMEX Henry Hub financial swaps. 

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 year.

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  outstanding.  AltaGas  may  also  enter  into  foreign  exchange  forward  derivatives  to  manage  the  risk  of 

fluctuating cash flows and earnings due to variations in foreign exchange rates as well as to benefit from favorable movements 

in  the  rates.  Any  hedges  transacted  are  subject  to  risk  limits  and  guidelines  and  are  actively  monitored  and  managed  by 

AltaGas’ risk management team to ensure they align with AltaGas’ overall financial strategy.

▪

▪

As  at  December  31,  2023,  Management  has  designated  US$715  million  of  outstanding  loans  as  a  net  investment 
hedge  to  hedge  against  the  currency  translation  effect  of  its  foreign  investments  (December  31,  2022  -  US$281 
million). 

For  the  year  ended  December  31,  2023,  a  $25  million  after-tax  unrealized  gain  on  the  net  investment  hedge  was 
recorded in other comprehensive income (2022 - after-tax unrealized loss $15 million). 

As  at  December  31,  2022, AltaGas  did  not  have  any  outstanding  foreign  exchange  forward  contracts. The  following  foreign 

exchange forward contracts are outstanding as at December 31, 2023:

For the year ended December 31, 2023, AltaGas had pre-tax gains on foreign exchange contracts of $25 million. Of this, an 

unrealized gain of less than $1 million, as well as a realized gain of less than $1 million related to foreign exchange contracts 

entered  into  for  the  purpose  of  risk  associated  with  cash  management,  was  recorded  in  the  Consolidated  Statements  of 

Income under the line item "foreign exchange gains" (year ended December 31, 2022 - $nil). Additionally, an unrealized gain of 

$19  million,  as  well  as  a  realized  gain  of  $6  million  related  to  foreign  exchange  contracts  entered  into  for  the  purpose  of 

managing income statement risk, was recorded in the Consolidated Statements of Income under the line item "revenue" (year 

ended December 31, 2022 - $nil).

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. 

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, 2023, a pre-tax loss of $8 million (2022 - pre-tax loss of less 

than $1 million) was recorded related to HDD and CDD instruments.

management activities.

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 acquisition of 

WGL  Holdings,  Inc.  (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 Ltd. – 2023 MD&A and Financial Statements - 49

 
 
 
 
 
AltaGas or any non-Ring Fenced Entity Affiliate, including any indebtedness or other contractual obligations of AltaGas, and 

the  Ring  Fenced  Entities  do  not  bear  any  liability  for  indebtedness  or  other  contractual  obligations  of  any  non-Ring  Fenced 

Entity, and vice versa.

Cash from operations increased by $582 million for the year ended December 31, 2023 compared to 2022, primarily due to 

favourable variances in the net change in operating assets and liabilities, partly offset by lower net income after taxes (after 

adjusting  for  non-cash  items).  The  majority  of  the  variance  in  net  change  in  operating  assets  and  liabilities  was  due  to 

increased cash flow from accounts receivable due to fluctuations in commodity prices, sales volumes, and weather, and higher 

cash flows from inventory as a result of increased volumes held, partially offset by lower cash flow from accounts payable and 

accrued  liabilities  due  to  fluctuations  in  commodity  prices,  and  lower  cash  flows  from  regulatory  liabilities  primarily  due  to 

overall warmer weather experienced by the Utilities segment.

The decrease in the working capital ratio was primarily due to decreases in assets held for sale related to the Alaska Utilities 

Disposition, accounts receivable, inventory, and risk management assets, as well as an increase in current portion of long-term 

debt. This was partially offset by decreases in liabilities associated with assets held for sale, accounts payable and accrued 

liabilities,  short-term  debt,  regulatory  liabilities,  and  risk  management  liabilities. 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, 2023 was $199 million, compared to $997 million in 2022. 

Investing activities for the year ended December 31, 2023 primarily included proceeds of approximately $1.1 billion from the 

disposition  of  assets  primarily  related  to  the Alaska  Utilities  Disposition  and  additional  proceeds  received  for  the  favourable 

settlement of outstanding contingencies on the sale of Goleta, partially offset by expenditures of approximately $943 million for 

property, plant, and equipment and intangible assets, the cash payment, net of cash acquired, of $327 million for the Pipestone 

Acquisition,  and  approximately  $4  million  of  net  contributions  to  equity  investments.  Investing  activities  for  the  year  ended 

December  31,  2022  included  expenditures  of  approximately  $958  million  for  property,  plant,  and  equipment  and  intangible 

assets,  and  a  cash  payment  of  approximately  $285  million  for  the  purchase  of  the  remaining  non-controlling  interest  of 

Petrogas, partially offset by proceeds of $245 million from the disposition of assets primarily related to the disposition of the

interest in the Aitken Creek processing facilities, a 60 MW stand-alone energy development project in Goleta, California, and a 

power plant in Brush, Colorado, as well as approximately $1 million of contributions to equity investments. 

Financing Activities 

Cash used in financing activities for the year ended December 31, 2023 was $882 million, compared to cash from financing 

activities of $435 million in 2022. Financing activities for the year ended December 31, 2023 were primarily comprised of net 

repayments  under  credit  facilities  of  $678  million,  repayments  of  long-term  debt  of  $338  million,  dividends  of  $343  million, 

redemption of preferred shares of $200 million, purchase of marketable securities in connection with debt defeasance of $193 

million, and distributions to non-controlling interests of $18 million, partially offset by long-term debt issuances of $673 million, 

issuance of subordinated hybrid notes, net of issuance costs of $198 million, and net proceeds from common shares issued on 

the exercise of options granted pursuant to AltaGas' share option plan ("Share Options") of $17 million. Financing activities for 

the year ended December 31, 2022 were primarily comprised of long-term debt issuances of $718 million, net issuances under 

credit facilities of $466 million, issuance of subordinated hybrid notes, net of debt issuance costs of $544 million, issuances of 

short-term debt of $128 million, and net proceeds from common shares issued on the exercise of Share Options of $25 million, 

partially offset by repayments of long-term debt of $513 million, dividends of $338 million, redemption of preferred shares of 

$574 million, and distributions to non-controlling interests of $21 million.

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 and debt classified as held for sale), and subordinated hybrid notes, 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.

Amounts  drawn  include  commercial  paper  that  is  supported  by  the  long  term  facilities.  WGL  and  Washington  Gas  have  the  right  to  request  additional 
borrowings of up to US$100 million with the bank’s approval, for a total of US$400 million and US$550 million on their respective facilities.

In addition to the facilities listed above, AltaGas has demand Letter of Credit facilities of $451 million (December 31, 2022 - 

$461 million). At December 31, 2023, there were letters of credit for $252 million (December 31, 2022 - $198 million) issued on 

these  facilities  and  an  additional  less  than  $1  million  (December  31,  2022  -  less  than  $1  million)  issued  on  the  Company's 

revolving credit facilities.

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, 2023, commercial paper outstanding totaled $461 million 

for WGL and Washington Gas (December 31, 2022 – $679 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, 2023 and December 31, 2022.

On March 31, 2023, a short form base shelf prospectus for the issuance of certain types of future public debt and/or equity 

issuances was filed to replace the short form base shelf prospectus dated February 22, 2021. This enables AltaGas to access 

the Canadian capital markets on a timely basis during the 25-month period that the short form base shelf prospectus remains

Critical Accounting Estimates 

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 

made  using  careful  judgment.  AltaGas’  significant  accounting  policies  are  contained  in  the  notes  to  the  2023  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: 

AltaGas Ltd. – 2023 MD&A and Financial Statements - 57

 
 
 
 
 
 
 
 
 
Regulatory Assets and Liabilities

SEMCO  and  Washington  Gas  engage  in  the  delivery  and  sale  of  natural  gas.  SEMCO  is  regulated  by  the  MPSC,  and 

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.  Based  on  the  valuation  approach,  the  fair  value  used  in  the  quantitative  impairment  test  of  goodwill  requires 

determining  appropriate  market  multiples  of  earnings  or  estimating  future  cash  flows  as  well  as  appropriate  discount  rates. 

AltaGas has assessed goodwill for impairment as at December 31, 2023 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 

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 

AltaGas Ltd. – 2023 MD&A and Financial Statements - 58

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. 

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  2023 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. 

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 

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, 2023, 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 

AltaGas Ltd. – 2023 MD&A and Financial Statements - 59

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, 2023, AltaGas adopted the following Financial Accounting Standards Board ("FASB") issued Accounting 

Standards Updates ("ASU"):

§

In  October  2021,  FASB  issued ASU  2021-08  "Business  Combinations  (Topic  805): Accounting  for  Contract Assets 

and Contract Liabilities from Contracts with Customers". The amendments in this ASU require an entity to recognize 

and  measure  contract  assets  and  liabilities  acquired  in  a  business  combination  in  accordance  with  Topic  606.  The 

adoption of this ASU did not have a material impact on AltaGas' consolidated financial statements. 

§

In March 2022, FASB issued ASU No. 2022-01 "Derivatives and Hedging (Topic 815): Fair Value Hedging - Portfolio 

Layer  Method". The  amendments  in  this ASU  will  allow  non-prepayable  financial  assets  to  be  included  in  a  closed 

portfolio hedged using the portfolio layer method and promote consistency in single and multiple hedged layers. The 

adoption of this ASU did not have a material impact on AltaGas' consolidated financial statements.

§

In  March  2022,  FASB  issued ASU  No.  2022-02  "Financial  Instruments  -  Credit  Losses  (Topic  326):  Troubled  Debt 

Restructurings  and  Vintage  Disclosures".  The  amendments  in  this  ASU  will  eliminate  the  accounting  guidance  for 

troubled  debt  restructurings  ("TDRs")  by  creditors  while  enhancing  disclosure  requirements  for  certain  loan 

refinancings and restructurings by creditors when a borrower is experiencing financial difficulty, as well as require the 

disclosure of current-period write offs by year of origination for financing receivables and net investments in leases. 

The adoption of this ASU did not have a material impact on AltaGas' consolidated financial statements.

§

In September 2022, FASB issued ASU No. 2022-04 "Liabilities (Subtopic 405-50) - Supplier Finance Programs". The 

amendments in this ASU will require a buyer in a supplier finance program to disclose the key terms of the program, 

the  amount  outstanding  at  the  end  of  the  period,  a  roll  forward  of  that  obligation  during  the  period,  and  where  the 

obligation is presented on the balance sheet. The adoption of this ASU did not have a material impact on AltaGas' 

consolidated financial statements. 

AltaGas Ltd. – 2023 MD&A and Financial Statements - 60

Future Changes in Accounting Principles

In  June  2022,  FASB  issued  ASU  No.  2022-03  "Fair  Value  Measurement  (Topic  820):  Fair  Value  Measurement  of  Equity 

Securities Subject to Contractual Sale Restrictions". The amendments in this ASU clarify that a contractual restriction on the 

sale of an equity security is not considered part of the unit of account of the equity security, and therefore, is not considered in 

measuring  fair  value.  In  addition,  an  entity  cannot,  as  a  separate  unit  of  account,  recognize  a  contractual  sale  restriction. 

Equity  securities  subject  to  contractual  sale  restrictions  also  require  certain  additional  disclosures.  The  amendments  in  this 

ASU are effective for fiscal years beginning after December 15, 2023 and should be applied prospectively with adjustments as 

a result of adopting this ASU being recognized in earnings. The adoption of this ASU is not expected to have a material impact 

on AltaGas' consolidated financial statements. 

In  March  2023,  FASB  issued  ASU  No.  2023-01  "Leases  (Topic  842):  Common  Control  Arrangements".  The  relevant 

amendments in this ASU allow entities to amortize leasehold improvements under common control over the economic life of 

the leasehold improvements as long as the lessee controlled the use of the leased asset. The amendments in this ASU are 

effective  for  fiscal  years  beginning  after  December  15,  2023,  including  interim  periods  within  those  fiscal  years  and  can  be 

applied using one of the following three methods: 1) prospectively to all new leasehold improvements recognized on or after 

the  date  the  entity  applies  the  amendments,  2)  prospectively  to  all  new  leasehold  improvements  recognized  on  or  after  the 

date  the  entity  applies  the  amendments,  with  any  remaining  unamortized  balance  of  existing  leasehold  improvements 

amortized  over  their  remaining  useful  life  to  the  common-control  group  determined  at  that  date,  or  3)  retrospectively  to  the 

beginning of the period in which the entity first applied Topic 842, with any leasehold improvements that otherwise would not 

have  been  amortized  or  impaired  recognized  through  a  cumulative-effect  adjustment  to  opening  retained  earnings  at  the 

beginning  of  the  earliest  period  presented. The  adoption  of  this ASU  is  not  expected  to  have  a  material  impact  on AltaGas' 

consolidated financial statements.

In March 2023, FASB issued ASU No. 2023-02 "Investments - Equity Method and Joint Ventures (Topic 323) - Accounting for 

Investments in Tax Credit Structures Using the Proportional Amortization Method". The amendments in this ASU allow entities 

the option to elect to account for tax equity investments, regardless of the tax credit program from which the income tax credits 

are  received,  using  the  proportional  amortization  method  if  certain  conditions  are  met.  The  amendments  in  this  ASU  are 

effective for public business entities for fiscal years beginning after December 15, 2023, including interim periods within those 

fiscal years and can applied on either a modified prospective or retrospective basis. The adoption of this ASU is not expected 

to have a material impact on AltaGas' consolidated financial statements. 

In  October  2023,  FASB  issued  ASU  No.  2023-06  "Disclosure  Improvements".  The  amendments  in  this  ASU  modify  the 

disclosure or presentation requirements of a variety of topics in the codification as a result of FASB's decision to incorporate 

disclosures  referred  to  in  SEC  Release  No.  33-10532,  which  sought  to  simplify  SEC  disclosure  requirements.  The 

amendments  in  this ASU  allow  users  to  more  easily  compare  entities  subject  to  the  SEC's  existing  disclosures  with  those 

entities  that  were  not  previously  subject  to  the  SEC's  requirements.  This  Update  is  only  effective  upon  the  removal  of  the 

related disclosure from SEC regulations with an expiration of June 30, 2027. The adoption of this ASU is not expected to have 

a  material  impact  on  AltaGas'  consolidated  financial  statements  at  this  time,  but  may  have  an  impact  in  future  periods  as 

AltaGas is subject to the scope of this ASU. 

In  November  2023,  FASB  issued ASU  No.  2023-07  "Segment  Reporting  (Topic  280)".  This ASU  requires  all  public  entities 

required to report segment information in accordance with Topic 280 to provide: (1) annual and interim disclosure of significant 

segment  expenses  regularly  provided  to  the  chief  operating  decision  maker  ("CODM"),  (2)  annual  and  interim  disclosure  of 

other segment items, (3) annual disclosures about reportable segment profit or loss and assets currently required by Topic 280 

in  interim  periods,  (4)  disclosure  of  additional  measures  used  to  measure  a  segments  profit  or  loss  outside  of  GAAP,  (5) 

disclosure of the title and position of the CODM, and (6) a public entity that has a single reportable segment to provide all the 

disclosures required by this update and all existing segment disclosures in Topic 280. This update is effective for fiscal years 

AltaGas Ltd. – 2023 MD&A and Financial Statements - 61

beginning after December 31, 2023, and interim periods with fiscal years beginning after December 15, 2024. The adoption of 

this ASU will have an impact on AltaGas' segment disclosures. 

In December 2023, FASB issued ASU No. 2023-09 "Income Taxes (Topic 740): Improvements to Income Tax Disclosures". The 

amendments  in  this ASU  require  that  public  business  entities  on  an  annual  basis:  (1)  disclose  additional  categories  about 

federal,  state,  and  foreign  income  taxes  in  the  rate  reconciliation  table  and  (2)  provide  additional  information  for  reconciling 

items  that  meet  a  quantitative  threshold. Additionally,  entities  are  required  to  annually  disclose  disaggregated  income  from 

continuing  operations,  income  tax  expense,  and  income  taxes  paid  (net  of  refunds  received)  by  certain  tax  authorities  and 

jurisdictions. This update is effective for annual periods beginning after December 15, 2024. The adoption of this ASU will have 

an impact on AltaGas' income tax disclosures. 

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. 

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  have  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,  2023,  there  were  no  changes  made  to  AltaGas'  ICFR  that  materially 

affected, or are reasonably likely to materially affect, its ICFR or DCP. 

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, 2023 and concluded that as at December 31, 2023 AltaGas' DCP 

and ICFR were effective. 

Limitation on Scope

In accordance with the provisions under National Instrument 52-109, the scope of the evaluation does not include ICFR related 

to  the  Pipestone Acquisition,  which  closed  on  December  22,  2023. These  provisions  allow  an  issuer  to  exclude  a  business 

AltaGas Ltd. – 2023 MD&A and Financial Statements - 62

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 Pipestone Acquisition were excluded from management's evaluation of the 

effectiveness of AltaGas' ICFR as at December 31, 2023. Summary financial information of the Pipestone Acquisition included 

in the audited Consolidated Financial Statements as at and for the year ended December 31, 2023, includes total assets of 

approximately $887 million and revenues of approximately $14 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.

2022. See discussion in the Non-GAAP Financial Measures section of this MD&A. 

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 impact of the sale of AltaGas' interest in the Aitken Creek processing facilities in the second quarter of 2022; 

The impact of the Alaska Utilities Disposition in the first quarter of 2023; and

The impact of the Pipestone Acquisition in the fourth quarter of 2023.

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:

§  After-tax  transaction  costs  of  approximately  $27  million  and  $4  million  incurred  throughout  2023  and  2022,

MANAGEMENT'S REPORT  

The  Consolidated  Financial  Statements  of AltaGas  Ltd.  ("AltaGas",  the  "Corporation",  or  the  "Company")  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, 2023.

In accordance with the provisions under National Instrument 52-109, the scope of the evaluation does not include ICFR related 

to the Pipestone Acquisition, which closed on December 22, 2023. As such, the controls, policies, and procedures related to 

the Pipestone Acquisition were excluded from management's evaluation of the effectiveness of AltaGas' ICFR as at December 

31,  2023.  Summary  financial  information  of  the  Pipestone  Acquisition  included  in  the  audited  Consolidated  Financial 

Statements as at and for the year ended December 31, 2023, includes total assets of approximately $887 million and revenues 

of approximately $14 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.

The shareholders have appointed Ernst & Young LLP as independent external auditors to express an opinion as to whether 

the Consolidated Financial Statements present fairly, in all material respects, the Corporation’s consolidated financial position, 

results of operations, and cash flows in accordance with U.S. GAAP. Ernst & Young LLP is not required under securities law to 

express an opinion as to the effectiveness of the Corporation's internal control over financial reporting. The report of Ernst & 

Young LLP outlines the scope of its examination and its opinion on the Consolidated Financial Statements.

INDEPENDENT AUDITOR'S REPORT

To the Shareholders and Directors of AltaGas Ltd. 

Opinion 

We  have  audited  the  consolidated  financial  statements  of AltaGas  Ltd.  and  its  subsidiaries  (the  Group),  which  comprise  the 

consolidated  balance  sheets  as  at  December  31,  2023  and  2022,  and  the  consolidated  statements  of  income,  consolidated 

statements  of  comprehensive  income,  consolidated  statements  of  equity  and  consolidated  statements  of  cash  flows  for  the 

years then ended, and notes to the consolidated financial statements, including a summary of significant accounting policies. 

In  our  opinion,  the  accompanying  consolidated  financial  statements  present  fairly,  in  all  material  respects,  the  consolidated 

financial  position  of  the  Group  as  at  December  31,  2023  and  2022,  and  the  consolidated  results  of  its  operations  and  its 

consolidated cash flows for the years then ended in accordance with United States generally accepted accounting principles 

(“US GAAP”).

Basis for opinion

We conducted our audit in accordance with Canadian generally accepted auditing standards. Our responsibilities under those 

standards are further described in the Auditor’s responsibilities for the audit of the consolidated financial statements section of 

our report. We are independent of the Group in accordance with the ethical requirements that are relevant to our audit of the 

consolidated financial statements in Canada, and we have fulfilled our other ethical responsibilities in accordance with these 

requirements.  We  believe  that  the  audit  evidence  we  have  obtained  is  sufficient  and  appropriate  to  provide  a  basis  for  our 

opinion.

Key audit matters

Key  audit  matters  are  those  matters  that,  in  our  professional  judgment,  were  of  most  significance  in  the  audit  of  the 

consolidated  financial  statements  of  the  current  period.  These  matters  were  addressed  in  the  context  of  the  audit  of  the 

consolidated financial statements as a whole, and in forming the auditor’s opinion thereon, and we do not provide a separate 

opinion  on  these  matters.  For  the  matter  below,  our  description  of  how  our  audit  addressed  the  matter  is  provided  in  that 

context.

We  have  fulfilled  the  responsibilities  described  in  the  Auditor’s  responsibilities  for  the  audit  of  the  consolidated  financial 

statements  section  of  our  report,  including  in  relation  to  this  matter.  Accordingly,  our  audit  included  the  performance  of 

procedures  designed  to  respond  to  our  assessment  of  the  risks  of  material  misstatement  of  the  consolidated  financial 

statements. The results of our audit procedures, including the procedures performed to address the matter below, provide the 

basis for our audit opinion on the accompanying consolidated financial statements.

AltaGas Ltd. – 2023 MD&A and Financial Statements - 68

Key audit matter

As described in note 23 to the consolidated financial statements, AltaGas Ltd. enters into commodity 

Fair Value Measurement of Level 3 Derivatives

How our audit 
addressed the key 
audit matter

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, 2023, derivative assets of $82 million and derivative liabilities of $135 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 

Group  such  as  the  assumed  natural  gas  basis  prices  and  implied  volatilities  of  natural  gas  prices. 

These unobservable assumptions can be affected by future economic and market conditions.

To test the Group's valuation of Level 3 derivative instruments, our audit procedures included, among 

others:

•

•

•

•

•

Evaluated the appropriateness of the underlying valuation methodologies used by the Group.

For  a  sample  of  instruments,  we  independently  determined  the  significant  unobservable 

assumptions described above, calculated the resulting fair values and compared them to the 

Group’s estimates. 

For a sample of instruments, we obtained forward prices from independent sources, including 

broker  quotes,  evaluated  the  Group’s  assumptions  related  to  their  forward  curves  and 

obtained external confirmation of key contract terms from counterparties. 

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. 

Evaluated  the  adequacy  of  the  Level  3  fair  value  measurement  note  disclosure  in  the 

consolidated financial statements related to the matter.

Other information 

Management is responsible for the other information. The other information comprises:

• Management’s Discussion and Analysis

Our opinion on the consolidated financial statements does not cover the other information and we do not express any form of 

assurance conclusion thereon.

In connection with our audit of the consolidated financial statements, our responsibility is to read the other information and, in 

doing  so,  consider  whether  the  other  information  is  materially  inconsistent  with  the  consolidated  financial  statements  or  our 

knowledge obtained in the audit or otherwise appears to be materially misstated.

We obtained Management's Discussion and Analysis prior to the date of this auditor's report. If, based on the work we have 

performed, we conclude that there is a material misstatement of this other information, we are required to report that fact in this 

auditor's report. We have nothing to report in this regard.

AltaGas Ltd. – 2023 MD&A and Financial Statements - 69

Responsibilities of management and those charged with governance for the consolidated financial statements

Management  is  responsible  for  the  preparation  and  fair  presentation  of  the  consolidated  financial  statements  in  accordance 

with  US  GAAP,  and  for  such  internal  control  as  management  determines  is  necessary  to  enable  the  preparation  of 

consolidated financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the consolidated financial statements, management is responsible for assessing the Group’s ability to continue as 

a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting 

unless management either intends to liquidate the Group or to cease operations, or has no realistic alternative but to do so.

Those charged with governance are responsible for overseeing the Group’s financial reporting process.

Auditor’s responsibilities for the audit of the consolidated financial statements

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free 

from  material  misstatement,  whether  due  to  fraud  or  error,  and  to  issue  an  auditor’s  report  that  includes  our  opinion. 

Reasonable  assurance  is  a  high  level  of  assurance,  but  is  not  a  guarantee  that  an  audit  conducted  in  accordance  with 

Canadian generally accepted auditing standards will always detect a material misstatement when it exists. Misstatements can 

arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to 

influence the economic decisions of users taken on the basis of these consolidated financial statements.

As  part  of  an  audit  in  accordance  with  Canadian  generally  accepted  auditing  standards,  we  exercise  professional  judgment 

and maintain professional skepticism throughout the audit. We also:

•

Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud 

or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient 

and appropriate to provide a basis for our  opinion. The risk  of  not detecting a material misstatement resulting from 

fraud  is  higher  than  for  one  resulting  from  error,  as  fraud  may  involve  collusion,  forgery,  intentional  omissions, 

•

•

•

•

•

misrepresentations, or the override of internal control.

Obtain  an  understanding  of  internal  control  relevant  to  the  audit  in  order  to  design  audit  procedures  that  are 

appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Group’s 

internal control.

Evaluate  the  appropriateness  of  accounting  policies  used  and  the  reasonableness  of  accounting  estimates  and 

related disclosures made by management.

Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on the 

audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant 

doubt on the Group’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are 

required to draw attention in our auditor’s report to the related disclosures in the consolidated financial statements or, 

if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained 

up to the date of our auditor’s report. However, future events or conditions may cause the Group to cease to continue 

as a going concern.

Evaluate  the  overall  presentation,  structure  and  content  of  the  consolidated  financial  statements,  including  the 

disclosures, and whether the consolidated financial statements represent the underlying transactions and events in a 

manner that achieves fair presentation.

Obtain  sufficient  appropriate  audit  evidence  regarding  the  financial  information  of  the  entities  or  business  activities 

within  the  Group  to  express  an  opinion  on  the  consolidated  financial  statements.  We  are  responsible  for  direction, 

supervision and performance of the group audit. We remain solely responsible for our audit opinion. 

AltaGas Ltd. – 2023 MD&A and Financial Statements - 70

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the 

audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit. 

We  also  provide  those  charged  with  governance  with  a  statement  that  we  have  complied  with  relevant  ethical  requirements 

regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to 

bear on our independence, and where applicable, related safeguards.

From  the  matters  communicated  with  those  charged  with  governance,  we  determine  those  matters  that  were  of  most 

significance in the audit of the consolidated financial statements of the current period and are therefore the key audit matters. 

We  describe  these  matters  in  our  auditor’s  report  unless  law  or  regulation  precludes  public  disclosure  about  the  matter  or 

when,  in  extremely  rare  circumstances,  we  determine  that  a  matter  should  not  be  communicated  in  our  report  because  the 

adverse  consequences  of  doing  so  would  reasonably  be  expected  to  outweigh  the  public  interest  benefits  of  such 

communication.

The engagement partner on the audit resulting in this independent auditor’s report is Ann-Marie Brockett.

focused on delivering resilient and durable value for its stakeholders.

AltaGas' operating segments include the following:  

§

Utilities, which owns and operates franchised, cost-of-service, rate regulated natural gas distribution and storage utilities 

that  focus  on  providing  safe,  reliable,  and  affordable  energy  to  approximately  1.6  million  residential  and  commercial 

customers.  This  includes  operating  two  utilities  that  operate  across  four  major  U.S.  jurisdictions  with  a  rate  base  of 

approximately US$5.1 billion. The Utilities business also includes storage facilities and contracts for interstate natural gas 

transportation  and  storage  services,  as  well  as  WGL  Energy  Services,  an  affiliated  retail  energy  marketing  business, 

which  sells  natural  gas  and  electricity  directly  to  residential,  commercial,  and  industrial  customers  located  in  Maryland,

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"), U.S. GAAP 

reporting  is  generally  permitted  by  Canadian  securities  laws  for  companies  subject  to  reporting  obligations  under  U.S. 

securities  laws.  On  March  28,  2023, AltaGas  filed  Form  15  with  the  Securities  and  Exchange  Commission  ("SEC")  and  as 

such,  is  no  longer  an  SEC  issuer  and  can  no  longer  rely  on  the  provisions  of  NI  52-107.  Therefore,  AltaGas  sought  and 

obtained exemptive relief by the securities regulators in Alberta and Ontario to permit it to prepare its financial statements in 

accordance with U.S. GAAP. The Alberta Securities Commission exemption will terminate on or after the earlier of January 1, 

2027, the date to which AltaGas ceases to have activities subject to rate regulation, or the first day of AltaGas' fiscal year that 

commences on or following the latter of: a) the effective date prescribed by the IASB for a mandatory rate regulated standard; 

or b) two years after the IASB publishes the final version of a mandatory rate regulated standard. 

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  AltaGas'  investment  in  Mountain  Valley  Pipeline 

("MVP") This  methodology  is  used  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. 

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 

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.

COMPARATIVE AMOUNTS

Certain prior year comparative figures in the Consolidated Balance Sheets and notes to the Consolidated Financial Statements 

have been reclassified to conform to the current period presentation.

SIGNIFICANT ACCOUNTING POLICIES

Rate-Regulated Operations 

SEMCO, Washington Gas, Hampshire Gas, and, prior to the Alaska Utilities Disposition, ENSTAR (collectively "the Utilities") 

engage  in  the  delivery,  sale,  and  storage  of  natural  gas.  SEMCO  is  regulated  by  the  Michigan  Public  Service  Commission 

("MPSC"). 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,  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, 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. 

Accounts Receivable 

Receivables  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 further adjusted. Accounts are written off when collection 

efforts are complete and future recovery is unlikely. 

AltaGas Ltd. – 2023 MD&A and Financial Statements - 80

 
 
 
 
 
Inventory 

Inventory  consists  of  materials,  supplies,  natural  gas,  natural  gas  liquids,  crude  oil  and  condensates,  processed  finished 

products, and emission compliance instruments which are valued at the lower of cost or net realizable value. Inventory also 

includes  renewable  energy  credits  which  are  valued  using  the  specific  identification  method.  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.

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

1 to 43 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. – 2023 MD&A and Financial Statements - 81

 
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

6 to 20 years

3 to 20 years

Extraction and Transmission ("E&T") Contracts

25 years

Commodity contracts

7 to 13 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.

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 

Cash  inflows  and  outflows  related  to  derivative  instruments  are  classified  as  cash  from  operations  in  the  Consolidated 

Statements of Cash Flows.

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". 

AltaGas Ltd. – 2023 MD&A and Financial Statements - 83

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. 

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  HDDs  falls  above  or  below  the  contractual  HDDs  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 outstanding loans to hedge against the currency translation effect of 

its  foreign  investments.  In  2023,  AltaGas  began  to  designate  certain  commodity  financial  swaps  as  cash  flow  hedges  in 

accordance with ASC Topic 815. For more information, please refer to Note 23.

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.

AltaGas Ltd. – 2023 MD&A and Financial Statements - 84

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. 

Credit Losses

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 recognized using a 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 

long-term  revolving  committed  credit  facilities  in  an  amount  equal  to  or  greater  than  the  expected  maximum  short-term 

obligation.

AltaGas Ltd. – 2023 MD&A and Financial Statements - 85

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  certain  outstanding  loans  to  hedge  against  the  currency  translation  effect  of  its  foreign  investments. 

Accordingly, foreign exchange gains and losses, from the dates of designation, on the translation of these loans are included in 

OCI. Additionally, AltaGas may enter into foreign exchange forward derivatives to manage the risk of fluctuating cash flows and 

earnings due to variations in foreign exchange rates as well as to benefit from favorable movements in the rates. Any hedges 

transacted  are  subject  to  risk  limits  and  guidelines  and  are  actively  monitored  and  managed  by AltaGas’  risk  management 

team  to  ensure  they  align  with  AltaGas’  overall  financial  strategy.  Gains  and  losses  arising  from  the  settlements  of  the 

derivatives  entered  into  for  the  purpose  of  managing  income  statement  risk  are  included  in  the  line  item  "revenue"  on  the 

Consolidated Statements of Income, while gains and losses arising from the settlements of the derivatives entered into for the 

purpose of cash management are included in the line item "foreign exchange gains (losses)" on the Consolidated Statements 

of Income. For more information, please refer to Note 23.

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") for eligible employees, officers, and directors, which includes two types of 

awards:  restricted  units  ("RUs")  and  performance  units  ("PUs"). AltaGas’  RUs  and  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. All PUs are also subject to a 

performance  multiplier  ranging  from  0  to  2  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. Forfeitures are recognized when they occur instead of estimating the number of awards that are expected 

to vest. 

In  addition, AltaGas  has  a  deferred  share  unit  plan  ("DSUP")  for  directors,  officers,  and  eligible  employees  as  an  additional 

form  of  long-term  variable  compensation  incentive.  Although  the  DSUP  is  available  to  directors,  officers,  and  eligible 

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. 

Forfeitures are recognized when they occur instead of estimating the number of awards that are expected to vest.

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. 

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. 

AltaGas Ltd. – 2023 MD&A and Financial Statements - 87

 
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.  Any  tax  related  interest  and/or 

penalty incurred is included in interest expense.

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. 

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  portion  of  finance  lease  liabilities,  and  long-term  finance  lease 

liabilities in the Consolidated Balance Sheets.  

AltaGas Ltd. – 2023 MD&A and Financial Statements - 88

 
 
 
 
 
 
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. 

Variable lease payments are based on a rate. 

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.

ADOPTION OF NEW ACCOUNTING STANDARDS 

Effective January 1, 2023, AltaGas adopted the following Financial Accounting Standards Board ("FASB") issued Accounting 

Standards Updates ("ASU"): 

§

In  October  2021,  FASB  issued ASU  2021-08  "Business  Combinations  (Topic  805): Accounting  for  Contract Assets  and 

Contract  Liabilities  from  Contracts  with  Customers".  The  amendments  in  this  ASU  require  an  entity  to  recognize  and 

measure contract assets and liabilities acquired in a business combination in accordance with Topic 606. The adoption of 

this ASU did not have a material impact on AltaGas' consolidated financial statements.

§

In March 2022, FASB issued ASU No. 2022-01 "Derivatives and Hedging (Topic 815): Fair Value Hedging - Portfolio Layer 

Method".  The  amendments  in  this  ASU  will  allow  non-prepayable  financial  assets  to  be  included  in  a  closed  portfolio 

hedged using the portfolio layer method and promote consistency in single and multiple hedged layers. The adoption of 

this ASU did not have a material impact on AltaGas' consolidated financial statements.

§

In  March  2022,  FASB  issued  ASU  No.  2022-02  "Financial  Instruments  -  Credit  Losses  (Topic  326):  Troubled  Debt 

Restructurings and Vintage Disclosures". The amendments in this ASU will eliminate the accounting guidance for troubled 

debt  restructurings  ("TDRs")  by  creditors  while  enhancing  disclosure  requirements  for  certain  loan  refinancings  and 

restructurings by creditors when a borrower is experiencing financial difficulty, as well as require the disclosure of current-

period write offs by year of origination for financing receivables and net investments in leases. The adoption of this ASU 

did not have a material impact on AltaGas' consolidated financial statements.

§

In  September  2022,  FASB  issued  ASU  No.  2022-04  "Liabilities  (Subtopic  405-50)  -  Supplier  Finance  Programs".  The 

amendments in this ASU will require a buyer in a supplier finance program to disclose the key terms of the program, the 

amount outstanding at the end of the period, a roll forward of that obligation during the period, and where the obligation is 

presented  on  the  balance  sheet.  The  adoption  of  this  ASU  did  not  have  a  material  impact  on  AltaGas'  consolidated 

financial statements.

AltaGas Ltd. – 2023 MD&A and Financial Statements - 89

 
 
 
 
FUTURE CHANGES IN ACCOUNTING PRINCIPLES 

In  June  2022,  FASB  issued  ASU  No.  2022-03  "Fair  Value  Measurement  (Topic  820):  Fair  Value  Measurement  of  Equity 

Securities Subject to Contractual Sale Restrictions". The amendments in this ASU clarify that a contractual restriction on the 

sale of an equity security is not considered part of the unit of account of the equity security, and therefore, is not considered in 

measuring  fair  value.  In  addition,  an  entity  cannot,  as  a  separate  unit  of  account,  recognize  a  contractual  sale  restriction. 

Equity  securities  subject  to  contractual  sale  restrictions  also  require  certain  additional  disclosures.  The  amendments  in  this 

ASU are effective for fiscal years beginning after December 15, 2023 and should be applied prospectively with adjustments as 

a result of adopting this ASU being recognized in earnings. The adoption of this ASU is not expected to have a material impact 

on AltaGas' consolidated financial statements.

In  March  2023,  FASB  issued  ASU  No.  2023-01  "Leases  (Topic  842):  Common  Control  Arrangements".  The  relevant 

amendments in this ASU allow entities to amortize leasehold improvements under common control over the economic life of 

the leasehold improvements as long as the lessee controlled the use of the leased asset. The amendments in this ASU are 

effective  for  fiscal  years  beginning  after  December  15,  2023,  including  interim  periods  within  those  fiscal  years  and  can  be 

applied using one of the following three methods: 1) prospectively to all new leasehold improvements recognized on or after 

the  date  the  entity  applies  the  amendments,  2)  prospectively  to  all  new  leasehold  improvements  recognized  on  or  after  the 

date  the  entity  applies  the  amendments,  with  any  remaining  unamortized  balance  of  existing  leasehold  improvements 

amortized  over  their  remaining  useful  life  to  the  common-control  group  determined  at  that  date,  or  3)  retrospectively  to  the 

beginning of the period in which the entity first applied Topic 842, with any leasehold improvements that otherwise would not 

have  been  amortized  or  impaired  recognized  through  a  cumulative-effect  adjustment  to  opening  retained  earnings  at  the 

beginning  of  the  earliest  period  presented. The  adoption  of  this ASU  is  not  expected  to  have  a  material  impact  on AltaGas' 

consolidated financial statements.

In March 2023, FASB issued ASU No. 2023-02 "Investments - Equity Method and Joint Ventures (Topic 323) - Accounting for 

Investments in Tax Credit Structures Using the Proportional Amortization Method". The amendments in this ASU allow entities 

the option to elect to account for tax equity investments, regardless of the tax credit program from which the income tax credits 

are  received,  using  the  proportional  amortization  method  if  certain  conditions  are  met.  The  amendments  in  this  ASU  are 

effective for public business entities for fiscal years beginning after December 15, 2023, including interim periods within those 

fiscal years and can applied on either a modified prospective or retrospective basis. The adoption of this ASU is not expected 

to have a material impact on AltaGas' consolidated financial statements. 

In  October  2023,  FASB  issued  ASU  No.  2023-06  "Disclosure  Improvements".  The  amendments  in  this  ASU  modify  the 

disclosure or presentation requirements of a variety of topics in the codification as a result of FASB's decision to incorporate 

disclosures  referred  to  in  SEC  Release  No.  33-10532,  which  sought  to  simplify  SEC  disclosure  requirements.  The 

amendments  in  this ASU  allow  users  to  more  easily  compare  entities  subject  to  the  SEC's  existing  disclosures  with  those 

entities  that  were  not  previously  subject  to  the  SEC's  requirements.  This  Update  is  only  effective  upon  the  removal  of  the 

related disclosure from SEC regulations with an expiration of June 30, 2027. The adoption of this ASU is not expected to have 

a  material  impact  on  AltaGas'  consolidated  financial  statements  at  this  time,  but  may  have  an  impact  in  future  periods  as 

AltaGas is subject to the scope of this ASU.

In  November  2023,  FASB  issued ASU  No.  2023-07  "Segment  Reporting  (Topic  280)".  This ASU  requires  all  public  entities 

required to report segment information in accordance with Topic 280 to provide: (1) annual and interim disclosure of significant 

segment  expenses  regularly  provided  to  the  chief  operating  decision  maker  ("CODM"),  (2)  annual  and  interim  disclosure  of 

other segment items, (3) annual disclosures about reportable segment profit or loss and assets currently required by Topic 280 

in  interim  periods,  (4)  disclosure  of  additional  measures  used  to  measure  a  segments  profit  or  loss  outside  of  GAAP,  (5) 

disclosure of the title and position of the CODM, and (6) a public entity that has a single reportable segment to provide all the 

disclosures required by this update and all existing segment disclosures in Topic 280. This update is effective for fiscal years 

beginning after December 31, 2023, and interim periods with fiscal years beginning after December 15, 2024. The adoption of 

this ASU will have an impact on AltaGas' segment disclosures. 

In December 2023, FASB issued ASU No. 2023-09 "Income Taxes (Topic 740): Improvements to Income Tax Disclosures". The 

amendments  in  this ASU  require  that  public  business  entities  on  an  annual  basis:  (1)  disclose  additional  categories  about 

federal,  state,  and  foreign  income  taxes  in  the  rate  reconciliation  table  and  (2)  provide  additional  information  for  reconciling 

items  that  meet  a  quantitative  threshold. Additionally,  entities  are  required  to  annually  disclose  disaggregated  income  from 

continuing  operations,  income  tax  expense,  and  income  taxes  paid  (net  of  refunds  received)  by  certain  tax  authorities  and 

jurisdictions. This update is effective for annual periods beginning after December 15, 2024. The adoption of this ASU will have 

an impact on AltaGas' income tax disclosures. 

3.   Pipestone Acquisition 

On  December  22,  2023,  AltaGas  closed  the  previously  announced  acquisition  of  natural  gas  processing  and  storage 

infrastructure assets in the Pipestone area of the Alberta Montney (the "Pipestone Acquisition") with Tidewater Midstream and 

Infrastructure  Ltd.  ("Tidewater")  for  consideration  upon  close  of $328  million  in  cash  and  approximately  12.5  million AltaGas 

common shares, inclusive of working capital and other adjustments. The Pipestone Acquisition includes the Pipestone natural 

gas processing facility Phase I, the Pipestone Phase II expansion project which is being developed, the Dimsdale natural gas 

storage facility, the Pipestone condensate truck-in/truck-out terminal, and the associated gathering pipeline systems required 

to operate these assets. Following the completion of key de-risking milestones in December 2023, AltaGas declared a positive 

final investment decision ("FID") on the Pipestone Phase II expansion project.

AltaGas  accounted  for  the  acquisition  as  a  business  combination  using  the  acquisition  method  of  accounting  whereby  the 

acquired  assets  and  assumed  liabilities  are  recorded  at  their  estimated  fair  values  at  the  date  of  acquisition. The  excess  of 

purchase  price  over  estimated  fair  values  of  assets  acquired  and  liabilities  assumed  is  recognized  as  goodwill  at  the 

acquisition date.

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  22,  2023.  The  purchase  price  allocation  is  preliminary  and 

reflects  Management’s  current  best  estimate  of  the  fair  value  of  the  acquired  assets  and  liabilities  based  on  the  analysis  of 

information  obtained  to  date.  Management  is  continuing  to  obtain  specific  information  to  support  the  valuation  of  current 

assets,  property,  plant  and  equipment,  intangible  assets,  long  term  investments  and  other  assets,  current  liabilities,  asset 

retirement  obligations,  deferred  taxes,  and  contingencies.  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 preliminary purchase price allocation includes goodwill of approximately $133 million. The goodwill is primarily related to 

incremental growth opportunities in the Midstream business as a result of the acquisition 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, 2023 of approximately $10 million were incurred and included 

in the "cost of sales" and "operating and administrative" line items on the Consolidated Statements of Income. For the period 

from close of the transaction through December 31, 2023, the Pipestone assets have generated approximately $14 million in 

revenues and less than $1 million in net income after taxes.  

The following supplemental unaudited, pro forma consolidated financial information for the years ended December 31, 2023 

and  2022  gives  effect  to  the  Pipestone  Acquisition  as  if  it  had  closed  on  January  1,  2022.  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 

Pipestone Acquisition  taken  place  at  the  beginning  of  2022,  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 Tidewater in 

relation to the Pipestone Acquisition. Proforma net income after taxes has also been adjusted for finance costs associated with 

credit facilities used to fund the acquisition and the related tax impacts. For the year ended December 31, 2023, the total after-

tax pro forma adjustments decreased net income after taxes by $6 million (2022 – $9 million).

4.   Dispositions

Alaskan Utilities

On March 1, 2023, AltaGas closed the sale of its 100 percent interest in ENSTAR and 65 percent indirect interest in CINGSA 

and other ancillary operations ("Alaska Utilities Disposition"), for consideration of approximately $1.1 billion (US$800 million), 

prior to closing adjustments. As a result, AltaGas recognized a pre-tax gain on disposition of approximately $304 million in the 

Consolidated Statements of Income under the line item "other income" for the year ended December 31, 2023. 

Energy Storage Development Project 

In the first quarter of 2022, AltaGas completed the sale of a 60 MW stand-alone energy storage development project in Goleta, 

California  for  total  proceeds  of  $20  million  (US$15  million),  subject  to  certain  contingencies.  In  February  2023,  the  parties 

reached  an  agreement  on  outstanding  contingencies  and  as  a  result,  the  buyer  paid  AltaGas  an  additional  payment  of 

approximately  $11  million  (US$8  million)  which  was  recognized  as  a  pre-tax  gain  on  disposition  in  the  Consolidated 

Statements of Income under the line item "other income" for the year ended December 31, 2023.

Meade Escrow Proceeds

In  2019,  AltaGas  completed  the  disposition  of  its  investment  in  Meade  Pipeline  Co.  LLC  ("Meade"),  which  held  WGL 

Midstream's  indirect,  non-operating  interest  in  the  Central  Penn  pipeline.  Upon  close  of  the  sale,  various  escrow  accounts 

were established to provide the purchaser a form of recourse for the settlement of indemnification obligations. In the second 

quarter  of  2023,  AltaGas  received  approximately  $1  million  (US$1  million)  of  cash  proceeds  from  the  indemnity  escrow 

account.  As  a  result,  AltaGas  recognized  a  pre-tax  gain  on  disposition  of  approximately  $1  million  in  the  Consolidated 

Statements of Income under the line item "other income" for the year ended December 31, 2023.

In  2022, AltaGas  recorded  a  pre-tax  provision  of  $6  million  related  to  the Alton  Natural  Gas  Storage  Project  as  a  result  of 

updated  reclamation  cost  estimates.  Since AltaGas  has  abandoned  this  project,  the  resulting  property,  plant  and  equipment 

associated  with  the  estimated  reclamation  costs  was  impaired.  The  pre-tax  provisions  were  primarily  recorded  against 

property, plant and equipment.

12.   Variable Interest Entities 

Consolidated VIEs

AltaGas consolidates a variable interest entity ("VIE") 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 Ltd. – 2023 MD&A and Financial Statements - 98

 
 
 
    
 
 
 
 
 
 
 
 
 
 
 
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

On April 4, 2023, AltaGas LPG and Vopak formed the Ridley Island Energy Export Facility Limited Partnership ("REEF LP") to 

develop, own, and operate the Ridley Island Energy Export Facility ("REEF"). AltaGas’ subsidiaries and Vopak each hold a 50 

percent interest in REEF LP. The construction cost of REEF is being funded by AltaGas LPG and Vopak in proportion to their 

respective interests in REEF LP. As part of the project definitive agreements, AltaGas entered into a long-term agreement for 

100 percent of the capacity of REEF with REEF LP. Additionally, AltaGas and certain of its subsidiaries have been contracted 

to provide operating and project development services to REEF LP. 

AltaGas  has  determined  that  REEF  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 its control of all operating and commercial aspects of the 

project. In addition, AltaGas has the obligation to absorb the losses and the right to receive the benefits that could potentially 

be  significant  to  REEF  LP  through  the  long-term  agreement  for  the  capacity  of  REEF.  As  such,  AltaGas  has  consolidated 

REEF LP.

The assets of REEF LP are the property of REEF LP and are not available to AltaGas for any purpose other than as described 

in  the  long-term  capacity  agreement.  REEF  LP’s  asset  balances  can  only  be  used  to  settle  its  own  obligations  and  the 

liabilities of REEF 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  REEF.  With  the  commencement  of  commercial 

operations at REEF, the terms of the long-term capacity agreement between AltaGas LPG and REEF LP provide for a return 

on and of capital and reimbursement of REEF's operating costs by AltaGas LPG in accordance with the terms set out in the 

agreement.

AltaGas has determined that AltaGas Hybrid Trust 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  its  role  as  the  sole  administrative  agent.  In  addition, 

AltaGas  has  the  obligation  to  absorb  the  administrative  expenses  that  are  significant  to  the  trust  through  the  associated 

administrative agreement. As such, AltaGas has consolidated the AltaGas Hybrid Trust.

Unconsolidated VIE 

Strathcona Storage Limited Partnership ("SSLP") 

AltaGas owns an interest in SSLP, a partnership formed with ATCO Energy Solutions Ltd. to construct, operate, and maintain 

underground NGL storage caverns at Fort Saskatchewan, Alberta. The facility currently has five underground NGL storage salt 

caverns.

As at December 31, 2023, AltaGas held a 40 percent equity investment in SSLP with a carrying value of $130 million (2022 - 

$130 million). SSLP is not consolidated by AltaGas and instead is accounted for by the equity method of accounting. AltaGas 

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. The maximum financial exposure to loss as a result of the involvement with this VIE is equal to AltaGas' 

net investment in SSLP.

(b)

The  equity  method  is  considered  appropriate  because  MVP  is  an  LLC  with  specific  ownership  accounts  and  ownership  between  five  and  fifty  percent, 
resulting in AltaGas exercising a more than minor influence over the investee's operating and financing policies. 
Equity income for the year ended December 31, 2023 relates to allowance for funds used during construction ("AFUDC") as a result of the resumption of 
construction activities in June 2023.

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 MVP.

aggregate principal amount of US$225 million. In satisfaction of the discharge requirements outlined in the indenture, certain 

assets were transferred to the indenture trustee to be held in trust to satisfy the remaining principal and interest obligations of 

the Defeased Bonds. As a result, SEMCO has been legally released from being the primary obligor of the Defeased Bonds. At 

transaction close AltaGas recognized a pre-tax gain of $14 million on the derecognition of the Defeased Bonds under the line 

item "other income" for the year ended December 31, 2023.

settled (December 31, 2022 - $7 million). 

(b) 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, 2023 was $759 million (December 31, 2022 - $877 million).

The asset retirement obligations have been recorded in the Consolidated Financial Statements at estimated values discounted 

at  rates  between  2.0  and  8.4  percent  (December  31,  2022  -  between  2.0  to  8.4  percent)  and  are  expected  to  be  incurred 

between 2024 and 2141 (December 31, 2022 - between 2023 and 2140). 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  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, 2023, a liability of $12 million has been recorded on an undiscounted basis related to future environmental 

response costs (December 31, 2022 - $13 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,  2023,  AltaGas  estimated  the 

maximum  liability  associated  with  all  of  its  sites  to  be  approximately  $54  million  (December  31,  2022  -  $50  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, 2023, AltaGas reported a regulatory asset of $16 million (December 31, 2022 - $15 million) for the portion 

of environmental response costs that are expected to be recoverable in future rates (Note 21).

In 2023, AltaGas received a Directive Letter from the Department of Energy and Environment ("DOEE") related to a MGP that 

was  formerly  owned  by  Washington  Gas  known  as  the  “West  Station  Gas  Works.”  The  Directive  Letter  requests  certain 

information and a site investigation. AltaGas is unable to estimate the total amount of potential costs or timing associated with 

a site investigation at this time. AltaGas has accrued an amount for estimated information request response costs based on a 

potential range of estimates.

As  at  December  31,  2023,  the  Corporation  had  tax-effected  non-capital  losses  of  approximately  $282  million,  which  will  be 

available to offset future taxable income. If not used, these losses will expire between 2028 and 2043.

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 2014 to 2022 remain subject to examination by taxation authorities. In 

the  United  States,  both  the  federal  and  state  tax  returns  for  the  years  2019  to  2022  remain  subject  to  examination  by  the 

taxation authorities. 

Management determined that the following provision was required for uncertainty on income taxes during the year:

21.   Regulatory Assets and Liabilities

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, 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.

This balance represents costs incurred in association with District of Columbia rate cases.
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  and  Washington  Gas  are  required  to  refund  to  ratepayers.  For  the  year  ended  December  31,  2023, 
$59  million  was  reclassified  from  a  regulatory  liability  to  a  regulatory  asset  to  be  consistent  with  the  normalization  provision  of  the TCJA  requiring  cost  of

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 crude 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. 

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 (including debt classified as held for sale), subordinated hybrid notes, 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, NGL, and crude 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. 

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.

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

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.
Excludes non-financial liabilities.

Financial assets and liabilities not included in the fair value hierarchy table include money market funds, short-term debt, and 

commercial paper. 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

Transfers between different levels of the fair value hierarchy may occur based on fluctuations in the valuation and on the level 

of observable inputs used to value the instruments from period to period. Transfers into and out of the different levels of 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, 2023 were due to an increase in valuations using observable market inputs.

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.

Any collateral posted that is not offset against risk management assets and liabilities is included in line item “prepaid expenses 

and  other  current  assets”  in  the  Consolidated  Balance  Sheets.  Collateral  received  and  not  offset  against  risk  management 

assets and liabilities is included in line item “customer deposits” in the Consolidated Balance Sheets.

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, 2023 and December 31, 2022, AltaGas has not posted 

any collateral related to its derivative liabilities that contained credit-related contingent features. The following table shows the 

aggregate fair value of all derivative instruments with credit-related contingent features that are in a liability position, as well as 

the  maximum  amount  of  collateral  that  would  be  required  if  specific  credit-risk-related  contingent  features  underlying  these 

agreements were triggered:

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. 

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 2034. 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  sells  power  to  the Alberta  Electric  System  Operator  at  market  prices,  as  well  as  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  2027.  As  at 

December 31, 2023, AltaGas had no intention to terminate any contracts prior to maturity. AltaGas had the following 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  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 outstanding. 

AltaGas may also enter into foreign exchange forward derivatives to manage the risk of fluctuating cash flows and earnings 

due to variations in foreign exchange rates as well as to benefit from favorable movements in the rates. Any hedges transacted 

are subject to risk limits and guidelines and are actively monitored and managed by AltaGas’ risk management team to ensure 

they align with AltaGas’ overall financial strategy.

AltaGas may designate its external U.S. dollar-denominated debt or certain U.S. dollar-denominated loans that may give rise 

to a foreign currency transaction gain or loss as a net investment hedge of its U.S. subsidiaries. As at December 31, 2023, 

AltaGas  has  designated  US$715  million  of  outstanding  loans  as  a  net  investment  hedge  (December  31,  2022  -  US$281

recorded in OCI (2022 - after-tax unrealized loss of $15 million).

As  at  December  31,  2022, AltaGas  did  not  have  any  outstanding  foreign  exchange  forward  contracts. The  following  foreign 

exchange forward contracts were outstanding as at December 31, 2023:

Cash Flow Hedges

In the normal course of business, WGL Energy Services purchases natural gas indexed to NYMEX Henry Hub to be sold to 

third party customers. WGL Energy Services' risk management objective and strategy is to protect earnings against the risk of 

price  fluctuations  associated  with  forecasted  NYMEX  Henry  Hub  purchases  through  the  use  of  the  NYMEX  Henry  Hub 

financial  swaps.  Beginning  April  1,  2023,  WGL  Energy  Services  began  prospectively  designating  its  NYMEX  Henry  Hub 

financial  swaps  as  cash  flow  hedges  in  accordance  with ASC  Topic  815  as  it  expects  that  the  hedging  relationship  will  be 

highly effective at achieving offsetting changes in cash flows attributable to the risk being hedged.

For hedging relationships that qualify as highly effective, the change in fair value of the hedging instrument will be recorded to 

AOCI.  Amounts  in  AOCI  will  be  reclassified  into  earnings  in  the  same  period  the  hedged  forecasted  transactions  affect 

earnings,  or  when  non-regulated  cost  of  energy-related  sales  is  recorded.  For  swaps  that  settle  the  month  ahead  of  the 

physical transaction, the swap impact will be reclassified into earnings in the subsequent month when the associated hedged 

transaction  is  recorded  into  earnings.  For  storage  inventory  purchases,  such  reclassification  into  earnings  will  be  based  on 

WGL Energy Services' inventory turnover schedules for finished goods in which the hedged natural gas purchases are used. 

When applicable, the ineffective portion of a cash flow hedge will immediately be recognized in earnings.

For  the  year  ended  December  31,  2023,  an  after-tax  unrealized  loss  on  outstanding  cash  flow  hedges  of  $9  million  was 

recorded  in  OCI  (year  ended  December  31,  2022  -  $nil).  For  the  year  ended  December  31,  2023,  a  loss  of  $1  million  was 

reclassified from AOCI to the income statement during the period under the line item "cost of sales".

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, 2023, approximately 84 percent of AltaGas’ total outstanding short-term and long-term debt was at 

fixed  rates  (December  31,  2022  -  78  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, 2023. 

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,  2023,  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 

AltaGas Ltd. – 2023 MD&A and Financial Statements - 120

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,  2023,  a  pre-tax  loss  of  less  than  $8  million  was  recorded 

related to these instruments (2022 - pre-tax loss of less than $1 million).

Accounts Receivable Past Due or Impaired

With  the  exception  of  accounts  receivable  which  are  due  in  one  year  or  less  as  summarized  in  the  following  table, AltaGas 

does not have any past due or impaired accounts receivable ("AR") as at December 31, 2023:

and power to end users.

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. 

Commodity Sales

Commodity  sales  also  include  gas  sales  to  residential,  commercial,  and  industrial  customers  in  certain  states  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.  

AltaGas Ltd. – 2023 MD&A and Financial Statements - 124

 
 
 
 
 
 
 
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.  AltaGas'  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 

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.

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. 

AltaGas Ltd. – 2023 MD&A and Financial Statements - 125

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. 

Contract Balances

As  at  December  31,  2023,  a  contract  asset  of  $40  million  (December  31,  2022  -  $41  million)  has  been  recorded  on  the 

Consolidated balance Sheets, of which $37 million ($36 million net of credit losses) is included within long-term investments 

and  other  assets  (December  31,  2022  –  $37  million  net  of  credit  losses)  and  $4  million  within  prepaid  expenses  and  other 

current assets (December 31, 2022 -  $4 million). This contract  asset represents  the difference in revenue recognized  under 

new  rates  in  blend-and-extend  contract  modifications  with  customers.  Revenue  from  these  contract  modifications  was 

recognized  at  the  pre-modification  rate  until  the  effective  date  of  the  contract  modification  on  the  original  contracts,  with  the 

excess  revenue  recorded  as  a  contract  asset. The  contract  asset  is  now  being  drawn  down  over  the  remaining  term  of  the 

modified contracts.

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

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. 

Defined Contribution Plan

AltaGas has a defined contribution ("DC") pension plan for substantially all employees. The pension cost recorded for the DC 

plan and DC Supplemental Executive Retirement Plan ("SERP") was $26 million for the year ended December 31, 2023 (2022 

- $25 million). 

AltaGas Ltd. – 2023 MD&A and Financial Statements - 130

 
 
 
 
 
 
 
Defined Benefit Plans 

AltaGas  has  three  defined  benefit  pension  plans  for  unionized  and  non-unionized  employees  in  the  United  States.  These 

include  a  qualified,  trusteed,  non-contributory  defined  benefit  pension  plan.  Actuarial  valuations  for  funding  purposes  are 

required annually for AltaGas’ U.S. defined benefit plans. The defined benefit plans are fully funded.

In  2021,  AltaGas  made  the  decision  to  wind-up  the  Canadian  defined  benefit  pension  plan  effective  March  31,  2022.  In 

October 2022, approval of the wind-up was received from the Alberta Superintendent of Pensions. On June 1, 2023, the wind-

up of the Canadian defined benefit pension plan was completed and as a result a settlement charge of $2 million was recorded 

under the line item "other income" for the year ended December 31, 2023. 

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)  and  a  non-funded  defined  benefit  restoration  SERP.  The  defined  benefit  SERP  was  closed  to  new  entrants 

beginning January 1, 2010 and the defined benefit restoration SERP was closed to new entrants in 2020. 

In 2023, AltaGas closed the Canadian SERP to new entrants and launched a new a defined contribution SERP effective July 

1, 2023, for eligible executives who join the Executive Committee on or after that date.

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. 

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  Health  and  Welfare 

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. Three of these plans are fully funded, and 

one is not funded.

Rabbi Trusts

Rabbi trusts of $9 million as at December 31, 2023 have been funded to satisfy the employee benefit obligations associated 

with WGL’s various pension plans (December 31, 2022 - $11 million). These balances are included in the "prepaid expenses 

and other current assets" and "long-term investments and other assets" line items on the Consolidated Balance Sheets.

For post-retirement benefit plans, the projected benefit obligation represents the accumulated benefit obligation.

(b) Calculation includes plan assets and liabilities that were classified as held for sale on December 31, 2022.

For the year ended December 31, 2023, AltaGas' defined benefit pension plans incurred actuarial losses primarily due to the 

decrease in discount rates, which were the result of a decrease in high-quality corporate bond yield curves in the Canadian 

and U.S. markets, while 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.  For  the  year  ended  December  31, 

2022, AltaGas' defined benefit and post-retirement benefit pension plans incurred actuarial gains primarily due to the increase 

in discount rates, which were the result of an increase in high-quality corporate bond yield curves in the Canadian and U.S. 

markets.

The  objective  for  fund  returns  for  the  pension  plans  in  the  United  States,  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,  if  applicable  to  the  fund.  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).

Upon  wind-up  of  the  Canadian  defined  benefit  plan,  the  remaining  assets  in  Canada  consist  of  cash  and  cash  equivalents 

attributable to the Canadian SERP and will continue to be held as such. The target asset mix for SEMCO plans is 33 percent 

fixed income assets, 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.

In  accordance  with ASC  Topic  820,  these  investments  are  measured  at  fair  value  using  net  asset  value  (NAV)  per  share  as  a  practical  expedient  and, 
therefore, have not been classified in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliations of the fair 
value hierarchy to the statements of net assets available for plan benefits.
As  at  December  31,  2023,  investments  in  pooled  separate  accounts  consisted  of  100  percent  income  producing  properties  located  in  the  United  States 
(December 31, 2022 - 100 percent).
As at December 31, 2023, investments in collective trust funds consisted primarily of 85 percent common stock of U.S. companies (December 31, 2022 - 79 
percent), 13 percent income producing properties located in the United States (December 31, 2022 - 16 percent), and 2 percent of short-term money market 
investments (December 31, 2022 - 5 percent). 
As at December 31, 2023, this net payable primarily represents pending trades for investments purchased net of pending trades for investments sold and 
interest  receivables. As  at December  31,  2022,  this  net  receivable  primarily  represents  pending  trades  for  investments  sold  and  interest  receivable  net  of 
pending trades for investments purchased.

As at December 31, 2023 and December 31, 2022, these investments consisted primarily of non-U.S. government bonds.
In  accordance  with ASC  Topic  820,  these  investments  are  measured  at  fair  value  using  net  asset  value  (NAV)  per  share  as  a  practical  expedient  and, 
therefore, have not been classified in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliations of the fair 
value hierarchy to the statements of net assets available for plan benefits.
As  at  December  31,  2023,  investments  in  commingled  funds  consisted  of  approximately  50  percent  common  stock  of  large-cap  U.S.  companies 
(December 31, 2022 - 49 percent), 24 percent U.S. Government fixed income securities (December 31, 2022 - 23 percent), and 26 percent corporate bonds 
for WGL’s post-retirement benefit plans (December 31, 2022 - 28 percent).

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 4.2 and 6.5 percent. The health care cost trend rates were assumed to decline to between 2.5 and 5.0 percent by 

2030.

Guarantees

AltaGas has guaranteed payments primarily for certain commitments on behalf of some of its subsidiaries. As at December 31, 

2023, AltaGas has no guarantees issued on behalf of 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.

Merger Commitments - District of Columbia

On August 9, 2023, the PSC of DC determined that AltaGas had failed to fulfill Term No. 5 Commitment of the PSC of DC’s 

merger approval order related to the June 2018 merger of AltaGas, WGL, and Washington Gas. On reconsideration, the PSC 

of DC confirmed, in relevant part, that it had credited AltaGas with causing the development of 2.4 MW of Tier one renewable 

resources  by  the  July  6,  2023  deadline,  and  that  the  Company  had  breached  its  Term  No.  5  Commitment  only  for  the 

remaining 7.6 MW. As directed by the PSC of DC, AltaGas, the District of Columbia Government ("DCG"), and the District of 

Columbia Office of People’s Counsel ("DC OPC") conducted negotiations in good faith to reach agreement on a penalty. On 

November 14, 2023, DCG reported that DCG and AltaGas believed that further negotiations would be fruitless. In a November 

21,  2023  motion,  AltaGas  confirmed  that  it  will  specifically  perform  its  Term  No.  5  obligations  by  continuing  to  cause  the 

development of the remaining 7.6 MW of solar renewable energy. AltaGas also proposed a penalty of approximately US$0.5 

million if the Company fulfills the balance of its renewable development obligation before the end of 2024, or US$0.6 million if 

the balance is not completed until after the end of 2024. On December 19, 2023, DCG proposed that AltaGas pay a penalty of 

approximately US$8 million. OPC proposed a penalty not less than DCG’s proposed penalty, to be paid before September 30, 

2024.  Management  believes  that  the  likelihood  of  a  civil  penalty  is  probable  however,  is  unable  to  estimate  the  maximum 

possible penalty.

Bcf is one billion cubic feet. 
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, during the prior 10 years for ENSTAR, and during the prior 30 years 
for  Washington  Gas. The  degree  day  variance  from  normal  for  ENSTAR  is  for  the  period  prior  to  the  close  of  the Alaska  Utilities  Disposition  on  March  1, 
2023. 
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.
Average for the period.

(6) NGL volumes refer to propane, butane, and condensate.
(7)
(8) Realized frac spread or NGL margin, expressed in dollars per barrel of NGL, is derived from sales recorded by the segment during the period for frac spread 
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.  
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 spread exposed volumes for the period.  

Fractionation volumes include NGL mix volumes processed.
