ANNUAL REPORT 2015
 

ONE OF NORTH AMERICA’S LARGEST  
ELECTRICAL UTILITIES (TSX: H) 

THIS IS 
HYDRO ONE 

Hydro One Limited (TSX: H) is Canada’s largest   
pure-play electricity transmission and distribution utility.   
It transmits and distributes electricity across the Province  
of Ontario, home to  38% of the country’s population.  
Hydro One became a publicly traded company on the  
Toronto Stock Exchange in November 2015 with the initial  
public offering by the Province of Ontario. 

Hydro One Limited has three reportable 
segments: the electrical transmission 
business, the electrical distribution 
business and a third business 
segment consisting of the company’s 
telecommunications business and certain 
corporate activities. 

Together, the company’s regulated 
transmission and distribution operations 
comprise approximately 88% of 
Hydro One’s assets and provide 
98% of its net revenues. 

Hydro One Telecom leverages the 
company’s telecommunications and 
tower assets to sell broadband 
fibre-optic capacity to other carriers, 
large corporations, government 
agencies, and healthcare and 
educational institutions. 

A new governance agreement between 
Hydro One and the Province of Ontario 
was announced on April 16, 2015. 
On July 17, 2015 a new independent 
Board of Directors was appointed to 
govern Hydro One through its transition 
into a publicly traded company. 

In November 2015, Hydro One Limited 
completed the initial public offering of 
15% of its common shares, with the 
proceeds of the offering going to the 
Province of Ontario in the first phase 
of its previously announced sale of the 
majority of the company to the public. 
The common shares are listed and trade 
on the Toronto Stock Exchange under 
the symbol “H”.

“Hydro One has a fully independent, diverse and deeply experienced Board 

of Directors to govern the Company’s business, allowing it to execute as an 

independently controlled and professionally managed commercial entity 

well positioned to generate growth and value for our shareholders...” 

DAVID F. DENISON 
Chair of the Board 

can help to lead the company forward. 

In addition to rolling up their sleeves 
in their critical new roles, the Hydro 
One management team led one of the 
largest and most successful initial public 
offerings in Canada in more than 
15 years. The shares of Hydro One 
began trading on the Toronto Stock 
Exchange on November 5th. 

To facilitate the change in ownership 
structure associated with the initial 
public offering, the province announced 
a new governance agreement between 
Hydro One and the province. This 
agreement ensures that the company 
is governed as an independent 
commercial entity going forward, 
providing confidence that the province 
is strictly playing the role of shareholder 
and not manager. Over the ensuing 
months, the new Board was assembled, 
drawing upon a diverse and 
accomplished group of proven leaders 
to govern Hydro One’s transformation 
with a renewed focus on customer 
service excellence and improved 
performance and reliability. My fellow 
Board members were selected for their 
independence, commercial experience 
and strong governance expertise 
concerning public companies, customer 
service, the electricity sector and public 
policy. 

As management and the Board work 
together to put in place a broad 
strategy to take Hydro One forward, 

Dear fellow shareholders, 

This was a seminal year of change and 
movement forward for Hydro One. 

The transformative journey began 
last spring when the Province 
of Ontario, previously the sole 
shareholder of Hydro One, made a 
series of announcements relating to 
the company, including that it would 
broaden the ownership through an 
initial public offering. While the 
province remains the company’s 
largest shareholder with 84% of the 
outstanding shares today, it has stated 
that it intends to make additional 
tranches of shares available to the 
public in stages, until it achieves its 
stated goal of reducing its ownership of 
Hydro One to 40%. 

An integral part of the company’s future 
is a renewed focus on customer service 
excellence and improved performance. 
During the past summer, the new 
Board announced the appointment 
of Mayo Schmidt as the company’s 
new President and Chief Executive 
Officer and Michael Vels as its Chief 
Financial Officer. Both executives 
have strong track records and 
demonstrated experience in leading the 
transformation of large, publicly traded 
companies into high performance, 
innovative and customer-focused 
organizations that enhance customer 
service, accelerate growth and create 
significant shareholder value. Together 
with the technical expertise of the 
existing Hydro One team, I believe they 

2     ANNUAL REPORT 2015  HYDRO ONE LIMITED    TSX: H     

work has already commenced across 
the company to strengthen customer 
service and performance excellence 
while putting in place initiatives to 
accelerate growth. 

I would like to recognize the important 
foundational work of the previous Chair, 
Sandra Pupatello, and her Board, 
and acknowledge the efforts of former 
President and Chief Executive Officer 
Carmine Marcello: his contribution and 
leadership was essential to Hydro One’s 
successful transition in 2015. Finally, 
I would like to thank the more than 
5,500 Hydro One employees who work 
tirelessly -- often around the clock and 
in hazardous weather and conditions 
-- to ensure that electricity is delivered 
safely, reliably and cost-effectively to the 
millions of citizens of Ontario. It is their 
efforts and commitment that enable this 
great company to deliver for you -- our 
shareholders, our customers and our 
communities -- and we look forward to 
taking your company even further 
in 2016. 

Thank you for your support, 

David F. Denison, OC 

Chair of the Board 
Hydro One Limited 

  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
 
 
“2015 was a year of tremendous positive change for Hydro One.  

The team is intently focused on transforming this significant North 

American electrical utility into a high-performance commercial 

organization with considerable muscle to accelerate growth and 

consistently deliver on its promises…” 

On behalf of our 5,500 employees, 
thank you for your investment and 
interest in our progress. I would 
like to thank the Board of Directors 
for its support and its confidence in 
management. I would also like to 
thank employees across Ontario for 
embracing Hydro One’s transformation 
and for their unwavering commitment to 
our customers. The future is bright. 

Mayo Schmidt 
President and CEO 
Hydro One Limited 

MAYO SCHMIDT 
President and CEO 

We know that we need to understand 
the needs of our customers and 
stakeholders, including First Nations 
and Métis communities. Serving these 
needs effectively and efficiently will 
drive our business decisions. Our 
strategy will ensure we are ready to 
adapt to the emerging technology 
landscape and position our business 
for success. We will build world-class 
competencies and position ourselves to 
grow in the long term. 

Hydro One is fortunate to operate in 
a stable and supportive regulatory 
environment with a transparent and 
predictable rate-setting process. The 
company plays an essential leadership 
role in the Ontario electricity industry. 

We are focused on making life better 
for our customers. We improve their 
lives by treating them with respect, by 
making certain our system is reliable 
and ready for the future, by managing 
our costs and thus the cost of our 
service, and by having highly trained 
men and women across Ontario who 
are ready to respond 24/7 when 
storms and extreme weather disrupt 
service. 

I believe we are uniquely positioned 
to make the most of the significant 
opportunities that lie ahead – and 
transform our business into a great 
Canadian company that stands out for 
its commitment to its customers and its 
performance for its shareholders.  

Dear fellow shareholders, 

It is clear that 2015 was a pivotal 
year for your company as Hydro 
One charted a new course towards 
becoming a publicly traded, 
increasingly customer-focused and 
performance-driven company that offers 
dependable dividends and robust, 
predictable growth prospects. 

It was a year of tremendous positive 
change that opened the door to a very 
bright future. 

The size, strength and efficiency of  
our electrical grid is critical to reliably  
delivering the electricity that sustains and  
secures the economic and social well-
being of every community in Ontario.  
This past year, the company made  
important investments to modernize and  
bolster the grid, investing approximately  
$1.7 billion in capital projects across  
both our transmission and distribution  
networks. Over the next few years, we  
will invest in significant infrastructure that  
is needed to maintain and modernize  
the critical electrical systems that we  
all depend on. We are stewards of this  
system, a mission we take very seriously.  

Hydro One is embarking on a journey 
to take a leadership position in the 
North American utility landscape. 
Through building on our strong 
foundation, we have the opportunity 
to become a leader in this dynamic 
and evolving environment. To enable 
this, we have undertaken a strategic 
planning process to define our future.

ELECTRICAL TRANSMISSION 
OPERATIONS 

Hydro One’s electrical transmission system totals approximately 29,000 

circuit kilometres of high-voltage lines, towers and transformers, operating 

at 500 kV, 230 kV or 115 kV. Hydro One’s grid transmits electricity from 

hydroelectric, nuclear, gas, wind and solar power generation sources 

to customers across Ontario, including 47 local distribution companies 

(LDCs), Hydro One’s own local distribution systems and 90 large industrial 

customers directly connected to the transmission system. 

The transmission operations service approximately 96% of the Province of Ontario 
by capacity and represent approximately 50% of the total assets and provide 50% 
of the net revenues of the company. 

The transmission system is linked to five jurisdictions adjacent to Ontario 
(Manitoba, Minnesota, Michigan, New York and Quebec) through high-voltage 
interconnections. The transmission operations are regulated by the Ontario Energy 
Board (OEB) and the National Energy Board (NEB), together with an operating 
agreement with the Independent Electricity System Operator (IESO) and the North 
American Electric Reliability Corporation (NERC). Hydro One is also a partner in 
the Bruce to Milton Limited Partnership, which is a unique partnership between the 
company and the Saugeen Ojibway Nation Finance Corporation, operating a 
176-kilometre long dual circuit transmission line between the Bruce Nuclear 
Generating Station and Hydro One’s Milton Switching Station. 

Our transmission assets can be divided into four functional categories: 

1. Transmission stations: These facilities are used for the delivery of power, 
voltage transformation and switching, and serve as connection points for both 
customers and generators. 

2. Transmission lines: Bulk transmission lines are main lines delivering power 

from generating stations or connections to receiving terminal stations. Area supply 
lines take power from the network and transmit it to customer supply transmission 
stations at customer load centres. 

3. Network operations: All transmission assets and many sub-transmission 

assets are managed from one central location, the Ontario Grid Control Centre. 

4. Telecommunications facilities: These facilities ensure the company’s 

telecommunications requirements are met, with respect to the protection and 
operation of the power system as well as voice and administrative data. Our 
subsidiary Hydro One Telecom sells excess capacity on our fibre-optic network.

OPERATIONS 

Hydro One’s electrical distribution system totals approximately 123,000 

circuit kilometres of lower-voltage power lines, poles and transformers, 

serving more than 1.3 million customers across Ontario. 

As Hydro One operates in both rural and urban centres across Ontario, customers 
benefit from our integrated planning and the coordinated operations of our

In June 2015, Hydro One announced the closing of its acquisition of Haldimand 
County Utilities, adding 21,200 customers to its local distribution network. In 
October, the closing of the acquisition of Woodstock Hydro Holdings Inc., including 
its wholly-owned subsidiary Woodstock Hydro Services Inc., added 15,800 
customers, to be integrated with Hydro One’s network in 2016. 

Hydro One Remote Communities Inc. operates and maintains the generation and  
distribution assets used to supply electricity to 21 remote communities across northern  
Ontario that are not connected to the electricity transmission grid.

SERVING 
CUSTOMERS 

Throughout 2015, Hydro One 
continued to put customers at the core 
of its decision-making, planning and 
execution. Every day the organization 
is focused on exceeding customer 
expectations. Whether it’s launching 
new customer-friendly tools or 
mobilizing hundreds of employees to 
restore power, Hydro One’s future path 
to success lies with our ability to exceed 
expectations. 

CUSTOMER COMMITMENTS 

In 2015, Hydro One was the first 
utility in Canada to launch Customer 
Commitments and service level 
guarantees. Developed with input from 
more than 40,000 customers and the 
company’s Customer Service Advisory 
Panel, these five commitments provide 
assurance to customers about the service 
they can expect from Hydro One:

We will provide you with a bill

We will make it easy to do 
business with us. 

W  e will courteously and 
promptly work to resolve any 
issues you may have. 

We will help you manage your 
electricity use. 

MOBILE OUTAGE APP 

Customer service includes keeping 
customers connected to the information 
that is most important to them. The 
company’s mobile outage app – 
available free to customers on their 
smartphones – was downloaded more 
than 60,000 times during 2015, 
totaling more than 286,000 since its 
launch in May 2012. 

OUTAGE ALERTS 

Drawing on the success of the mobile 
app, Hydro One was the first utility 
in Canada to launch personalized 
text and email alerts to customers, 
proactively informing them of outages 
that might affect their homes, cottages, 

farms or small businesses. Customers 

who register for this service receive 

alerts and updates on estimated times 

of restoration when an outage has 

been reported near their residences. 

Customers decide when and how they 

receive messages. To date, more than 

7,000 customers have signed up for 
 
the service.
 

OFFICE OF THE OMBUDSMAN 

To further support customer service, 
in October the company’s Board of 
Directors appointed Fiona Crean to the 
role of Ombudsman for Hydro One. 
Having most recently served as the City 
of Toronto’s ombudsman, Ms. Crean 
has worked in the area of complaints 
investigation and dispute resolution for 
more than 25 years. 

STORM RESPONSE 

Wind, snow and rain are a reality of 
life in Ontario. Across the province, 
the men and women of Hydro One are 
available 24 hours a day, seven days a 
week, to restore power for customers if 
the lights go out. 

From the state-of-the-art Ontario 
Grid Control Centre, highly trained 
employees monitor all potential events, 
including weather, solar storms and 
geomagnetic disturbances that could 
affect Hydro One’s system. The centre 
provides Hydro One with the 
industry-leading ability to remotely 
monitor and operate transmission 
equipment, respond to alarms and 
restore or reroute interrupted power. 

When an alert is issued, the entire 
organization begins mobilizing staff 
and equipment to ensure power is 
restored as efficiently as possible. This 
means moving crews and equipment 
to where they are needed to make sure 
that power can be restored safely and 
quickly. With a workforce trained to the 
highest standards, crews can travel more 
than 500 kilometres to aid in restoration. 

Working through holidays, in the 
harshest of conditions and in remote 
areas of the province, Hydro One 
employees not only restore power, but 
restore life back to normal for customers.

In 2015, 13 female engineering 
students received Hydro One’s Women 
in Engineering Scholarship for their 
outstanding achievements in electrical 
engineering. Winners receive a 
financial award along with a paid 
opportunity to work for Hydro One in a 
developmental student work placement. 
In celebration of National Aboriginal 
Day, in June Hydro One awarded  
12 students with the Leonard S. (Tony) 
Mandamin Scholarship, which is 
granted annually to First Nations, Métis 
or Inuit post-secondary students. 

CORPORATE SOCIAL 
RESPONSIBILITY

In January, Hydro One was designated 
as a Sustainable Electricity Company 
by the Canadian Electricity Association 
(CEA). This designation established 
by the CEA for utilities across 
Canada recognizes success building 
on the three foundational pillars of 
sustainability – environmental, social, 
and economic performance. It requires 
utilities to establish an Environmental 
Management System consistent with 
the ISO 14001 standard; to take the 
actions and meet the expectations laid 
out in the ISO 26000 Guidance on 
Social Responsibility. Hydro One is 
only the fourth electric utility in Canada 
to receive this designation. 

For further information on 
Hydro One’s commitments to 
customers, safety, communities 
and the environment, please

OurCommitment.

SAFETY,  
COMMUNITY 
AND THE 
ENVIRONMENT

SAFETY

The safety of the public, the 
communities Hydro One serves and the 
people of Ontario is every employee’s 
responsibility.

From proper job planning to a  
trained and highly-skilled workforce, 
Hydro One emphasizes the importance 
of a safe workplace across every line 
of business. The result of this focus was 
seen in 2015 as Hydro One achieved 
its ambitious health and safety target, 
recording only 1.68 incidents per 
200,000 hours worked.  

Hydro One was awarded the Electrical 
Safety Authority’s Powerline Safety 
Award for its community outreach 
with the company’s mobile Electricity 
Discovery Centre. More than 30,000 
visitors from 26 communities learned 
about electrical safety, how to conserve 
energy and the role Hydro One plays 
in the community. 

COMMUNITY

Hydro One believes in the importance 
of connecting with the communities 
where we live and work through 
sponsorships, donations, scholarship 
programs and volunteering. These 
charitable giving programs broadly 
support safety and injury prevention, 
education and community support. They 
are an important link to the hundreds of 
communities that the company serves 
across the province.

Community Investment
Furthering the company’s commitment to 
First Nations and Métis communities, in 
February 2015 Hydro One announced 
a three-year funding extension for 
Right to Play’s Promoting Life-skills in 
Aboriginal Youth program. Hydro One 
is investing $100,000 each year to 
support after-school programming, 
sport for developmental activities, youth 
leadership, and health and wellness 
education.

MANAGEMENT’S DISCUSSION AND ANALYSIS 

Overview 
Hydro One is the largest electricity transmission and distribution 
company in Ontario. Through its subsidiary, Hydro One Inc., Hydro 
One owns and operates substantially all of Ontario’s electricity 
transmission network, and is the largest electricity distributor in 
Ontario. Hydro One has three business segments: (i) Transmission 
Business; (ii) Distribution Business; and (iii) Other Business 
(telecommunications). 

Transmission Business 

Hydro One’s transmission business owns, operates and maintains 
Hydro One’s transmission system, which accounts for approximately 

Electricity transmitted (TWh) 
Transmission lines spanning the province (circuit-kilometres) 
Rate base (millions of Canadian dollars) 
Capital investments (millions of Canadian dollars) 

Note: TWh means terawatt-hours. 

Distribution Business 

Hydro One’s Distribution Business is the largest in Ontario and 
consists of the distribution system operated by Hydro One Inc.’s 
subsidiaries Hydro One Networks and Hydro One Remote 
Communities Inc. The Company’s Distribution Business is a rate-
regulated business that earns revenues mainly by charging distribution 
rates that must be approved by the OEB. The Distribution Business 
represented approximately 38% of the Company’s total assets as at 
December 31, 2015, and approximately 48% of its total revenues, 
net of purchased power, in 2015. 

Electricity distributed to Hydro One customers (TWh) 
Electricity distributed through Hydro One lines (TWh)1 
Distribution lines spanning the province (circuit-kilometres) 
Distribution customers (number of customers)

consists of the transmission system operated by Hydro One Inc.’s 
subsidiary, Hydro One Networks Inc. (Hydro One Networks), and a 
66% interest in B2M Limited Partnership (B2M LP), a limited 
partnership between Hydro One and the Saugeen Ojibway Nation 
in respect of the Bruce-to-Milton transmission line. The Company’s 
Transmission Business is a rate-regulated business that earns revenues 
mainly from charging transmission rates that are approved by the 
Ontario Energy Board (OEB). The Transmission Business represented 
approximately 50% of the Company’s total assets as at 
December 31, 2015, and approximately 50% of its total revenues, 
net of purchased power, in 2015.

power directly from the Independent Electricity System Operator (IESO). 

Other Business	 

Hydro One’s Other Business segment consists of the Company’s 
telecommunications business and certain corporate activities. The 
telecommunications business provides telecommunications support for 
the Company’s Transmission and Distribution Businesses, and also 
offers communications and IT solutions to organizations with 

broadband network requirements utilizing Hydro One Telecom Inc.’s 
(Hydro One Telecom) fibre optic network to provide diverse, secure 
and highly reliable connectivity. Hydro One’s other business segment 
is not rate-regulated. This segment represented approximately 12% of 
Hydro One’s total assets as at December 31, 2015, and 
approximately 2% of its total revenues, net of purchased power, in 
2015.

Primary Factors Affecting Results Of Operations 

Transmission Revenues 

Transmission revenues primarily consist of the Company’s transmission 
rates approved by the OEB which are charged based on the monthly 
peak electricity demand across Hydro One’s high-voltage network. 
Transmission rates are designed to generate revenues necessary to 
construct, upgrade, extend and support a transmission system with 
sufficient capacity to accommodate maximum forecasted demand 
and a regulated return on the Company’s investment. Peak electricity 
demand is primarily influenced by weather and economic conditions. 
Transmission revenues also include export revenues associated with 
transmitting electricity to markets outside of Ontario. Ancillary 
revenues include revenues from providing maintenance services to 
generators and from third-party land use. 

Distribution Revenues 

Distribution revenues include the distribution rates approved by the 
OEB and amounts to recover the cost of purchased power used by 
the customers of the distribution business. Distribution rates are 
designed to generate revenues necessary to construct and support 
local distribution system with sufficient capacity to accommodate 
existing and new customer demand and a regulated return on the 
Company’s investment. Accordingly, distribution revenues are 
influenced by distribution rates, the cost of purchased power, and the 
amount of electricity the Company distributes. Distribution revenues 
also include ancillary distribution service revenues, such as fees 
related to the joint use of Hydro One’s distribution poles by the 
telecommunications and cable television industries, as well as 
miscellaneous charges such as charges for late payments. 

Purchased Power Costs 

Purchased power costs are incurred by the distribution business and 
represent the cost of purchased electricity delivered to customers 
within Hydro One’s distribution service territory. These costs comprise 
the wholesale commodity cost of energy, in addition to wholesale 
market service and transmission charges levied by the Independent 
Electricity System Operator (IESO). Hydro One passes the cost of 
electricity that it delivers to its customers, and is therefore not exposed 
to wholesale electricity commodity price risk. 

Operation, Maintenance and 
Administration Costs 

Operation, maintenance and administration (OM&A) costs are 
incurred to support the operation and maintenance of the transmission 
and distribution systems, and other costs such as property taxes 
related to transmission and distribution lines, stations and buildings. 

Transmission OM&A costs are incurred to sustain the Company’s 
high-voltage transmission stations, lines and rights-of-way, and include 
preventive and corrective maintenance costs related to power 
equipment, overhead transmission lines, transmission station sites, and 
forestry control to maintain safe distance between line spans and 
trees. Distribution OM&A costs are required to maintain the 
Company’s low-voltage distribution system, and include costs related 
to distribution line clearing and forestry control to reduce power 
outages caused by trees, line maintenance and repair, as well as 
land assessment and remediation. Hydro One manages its costs 
through ongoing efficiency and productivity initiatives, while 
continuing to complete planned work programs associated with the 
development and maintenance of its transmission and distribution 
networks. 

Depreciation and Amortization 

Depreciation and amortization costs relate primarily to depreciation 
of the Company’s property, plant and equipment, and amortization 
of certain intangible assets and regulatory assets. Depreciation 
expense also includes the costs incurred to remove property, plant 
and equipment where no asset retirement obligations have been 
recorded on the balance sheet. 

Financing Charges 

Financing charges relate to the Company’s financing activities, and 
include interest expense on the Company’s long-term debt, gains and 
losses on interest rate swap agreements, net of interest earned on 
short-term and long-term investments. A portion of financing charges 
incurred by the Company is capitalized to the cost of property, plant 
and equipment associated with the periods during which such assets 
are under construction before being placed in-service. 

Income Taxes 

Hydro One and its subsidiaries were exempt from regular Canadian 
federal and Ontario income tax (Federal Tax Regime) and instead 
paid an equivalent amount referred to as payments in lieu of 
corporate income taxes (PILs) to the Ontario Electricity Financial 
Corporation (OEFC) under the Electricity Act (PILs Regime) until 
October 2015. Since then, Hydro One and its subsidiaries have 
been subject to the Federal Tax Regime. See further details in section 
“Other Developments – PILs Deemed Disposition Rules.”

MANAGEMENT’S DISCUSSION AND ANALYSIS 

Results of Operations 

Net Income 

Net income attributable to common shareholders for the year ended 
December 31, 2015 of $690 million is a decrease of $41 million 
or 5.6% from the prior year. Significant influences on net income 
included: 

•  milder weather in 2015 resulted in a decrease in transmission 

revenues, mainly due to lower average Ontario peak demand in 
2015 compared to 2014, particularly in June, November, and 
December; 

•  the effective income tax rate of 12.8% in 2015 compared to an 

effective tax rate of 10.6% in 2014;

lower costs related to remediating the Company’s customer

lower bad debt expenses; and 
lower preventative maintenance related to vegetation

in 2014, insurance proceeds related to 2013 floods at the 
Company’s Richview and Manby transformer stations were 
recorded as a reduction in 2014 OM&A costs and did not 
recur in 2015; and

Transmission Revenues 

Distribution Revenues 

The decrease of $52 million or 3.3% in transmission revenues for the 
year ended December 31, 2015 was primarily due to lower 
average monthly Ontario 60-minute peak demand due to industrial 
customers shifting energy use away from system-wide peaks in the 
winter months of 2015 and generally milder weather in 2015, which 
more than offset increased transmission rates for 2015. 

The increase of $46 million or 0.9% in distribution revenues for the 
year ended December 31, 2015 was primarily due to higher OEB-
approved distribution rates and higher purchased power costs, 
partially offset by decreased revenues due to the spin-off of Hydro 
One Inc.’s subsidiary, Hydro One Brampton Networks Inc. (Hydro 
One Brampton).

Transmission OM&A Costs 

The increase of $32 million or 8.1% in transmission OM&A costs for

following: 

•  expenses related to write-offs of project and inventory costs due to 

revisions of asset replacement strategies:

•  higher expenditures during 2015 related to work required to

•  in 2014, insurance proceeds related to 2013 floods at the 
Company’s Richview and Manby transformer stations were 
recorded as a reduction in 2014 OM&A costs and did not recur 
in 2015; partially offset by: 

•  decreased expenditures related to forestry control and line clearing 

on the Company’s transmission rights-of-way. 

Depreciation and Amortization 

The increase of $37 million or 5.1% in depreciation and 
amortization costs for the year ended December 31, 2015 
compared to last year was mainly due to the growth in capital assets 
as the Company continues to place new assets in-service, consistent 
with its ongoing capital investment program.

Distribution OM&A Costs 

The decrease of $109 million or 14.7% in distribution OM&A costs 
for the year ended December 31, 2015 was primarily due to the 
following: 

•	  a decrease in bad debt expense and lower expenditures related 
to remediation of the Company’s customer information system; 

•  decreased vegetation management expenditures relating to the 

distribution line clearing and forestry control; and 

•  lower volume of work associated with locating and restoring 

power outages; partially offset by 

•  increased costs associated with responding to power outages as 
a result of multiple wind storms during the fourth quarter of 2015. 

Other OM&A Costs 

The increase of $20 million or 35.7% in other OM&A costs for the 
year ended December 31, 2015 was primarily due to costs to 
integrate acquired local distribution companies and increased 
compensation costs. 

Income tax expense 

Income tax expense for the year ended December 31, 2015 
increased by $16 million compared to 2014, and the Company 
realized an effective tax rate of approximately 12.8% in 2015, 
compared to approximately 10.6% realized in 2014. The 
differences are primarily due to the following: 

•  lower capital cost allowance in excess of depreciation and 

amortization; and 

•  additional tax expense in connection with the spin-off of Hydro 

One Brampton; partially offset by 

•	  an income tax recovery recorded on the revaluation to fair market 
value of the tax basis of the assets of Hydro One Inc. and its 
subsidiaries in excess of the Departure Tax triggered when Hydro 
One exited the PILs Regime.

Non-GAAP Measures 

FFO and Adjusted FFO 

FFO is defined as net cash from operating activities, adjusted for the 
following: (i) changes in non-cash balances related to operations, 
(ii) dividends paid on preferred shares, and (iii) distributions to 
noncontrolling interest. Adjusted FFO is defined as FFO, adjusted for 
the impact of the deferred income tax asset that resulted as a 
consequence of leaving the PILs Regime and entering the Federal Tax 
Regime. Management believes that FFO and adjusted FFO are 

helpful as supplemental measures of the Company’s operating cash 
flows as they exclude timing-related fluctuations in non-cash operating 
working capital and cash flows not attributable to common 
shareholders, and, in the case of adjusted FFO, the impact of the 
IPO-related deferred income tax asset. As such, these measures 
provide a consistent measure of the cash generating performance of 
the Company’s assets.

Pro forma Adjusted non-GAAP Basic and 
Diluted EPS 

The following pro forma adjusted non-GAAP basic and diluted EPS 
has been prepared by management on a supplementary basis which 
assumes that the total number of common shares outstanding was 
595,000,000 in each of the years ended December 31, 2015 and 
2014. The supplementary pro forma disclosure is used internally by 
management subsequent to the IPO to assess the Company’s 

performance and is considered useful because it eliminates the 
impact of the issuance of common shares to the Province prior to the 
IPO. Prior to the IPO, the Province was the sole shareholder of Hydro 
One and disclosure of EPS did not provide meaningful information. 
EPS is considered an important measure and management believes 
that presenting it for all periods based on the number of outstanding 
shares on, and subsequent to, the IPO provides users with a basis to 
evaluate the operations of the Company with comparable companies 
and with prior periods.

Adjusted Net Cash from Operating Activities 

Adjusted net cash from operating activities is defined as net cash from 
operating activities, adjusted for the impact of the deferred income 
tax asset that resulted as a consequence of leaving the PILs Regime 
and entering the Federal Tax Regime. Management believes that this 

measure is helpful as a supplemental measure of the Company’s net 
cash from operating activities as it excludes the impact of the IPO-
related deferred income tax asset. As such, adjusted net cash from 
operating activities provides a consistent measure of the Company’s 
cash from operating activities compared to prior periods.

To the extent that adjusted net income is used in future continuous 
disclosure documents of Hydro One, it will be defined as net income, 
adjusted for certain items, including non-recurring items and other 
one-time items that management does not consider to be reflective of 
the operating performance of the Company. No such adjustments to 
net income are presented in this MD&A. Management believes that 
this measure will be helpful in assessing the Company’s financial and 
operating performance in the future. 

FFO, adjusted FFO, pro forma adjusted non-GAAP basic and diluted 
EPS, adjusted net cash from operating activities, and adjusted net 
income are not recognized measures under US GAAP and do not 
have a standardized meaning prescribed by US GAAP. They are 

therefore unlikely to be directly comparable to similar measures 
presented by other companies. They should not be considered in 
isolation nor as a substitute for analysis of the Company’s financial 
information reported under US GAAP. 

Summary of Sources and Uses of Cash 

Hydro One’s primary sources of cash flows are funds generated from 
operations, capital market debt borrowings and bank financing that 
are used to satisfy Hydro One’s capital resource requirements, 
including the Company’s capital expenditures, servicing and 
repayment of debt, and dividends.

Cash from Operating Activities 

Cash from Investing Activities 

Cash used in operations totalled $1,253 million for 2015 compared 
to cash from operations of $1,256 million in 2014. Cash from 
operations was affected by changes in deferred income tax assets 
that resulted as a consequence of leaving the PILs Regime and 
entering the Federal Tax Regime. Excluding this effect, cash from 
operations would have been $1,557 million for 2015, an increase 
of $301 million compared to prior year, mainly due to improved 
accounts receivable collections in 2015 and changes in regulatory 
accounts that impact revenue. 

Cash from Financing Activities 

Cash from financing activities of $2,954 million for 2015 compared 
to cash used in financing activities of $395 million in 2014. The 
increase in 2015 was primarily due to cash proceeds from common 
shares issued, and the issuance of short-term notes and long-term 
debt, partly offset by payment of dividends and repayment of long­
term debt. See section “Liquidity and Financing Strategy” for details 
of the Company’s liquidity and financing strategy. 

In 2015, Hydro One issued $350 million of long-term debt under its 
Medium-Term Note (MTN) Program, compared to $628 million of 
long-term debt issued in 2014. In 2015, Hydro One repaid 
$550 million in maturing long-term debt, compared to no long-term 
debt maturing or repaid in 2014. In addition, long-term debt totalling 
$35 million assumed as part of the Haldimand County Utilities Inc. 
(Haldimand Hydro) acquisition and the Woodstock Hydro Holdings 
Inc. (Woodstock Hydro) acquisition was repaid in 2015. 

In 2015, Hydro One paid dividends in the amount of $888 million 
($875 million of common share dividends and $13 million of 
preferred share dividends), compared to dividends totalling 
$287 million paid in 2014. Included in dividends paid in 2015 
was a special dividend paid to the Province prior to the completion 
of the IPO. 

In November 2015, Hydro One issued 2.6 billion common shares to 
the Province for cash proceeds of $2.6 billion prior to the completion 
of the IPO. 

Cash used in investing activities was $1,707 million for 2015 
compared to $1,326 million in 2014. The increase in 2015 was 
mainly due to higher capital investments in 2015 and the sale of an 
investment in 2014 for $250 million that did not recur in 2015. In 
2015, cash totalling $90 million was used to purchase Haldimand 
Hydro and Woodstock Hydro, compared to cash of $66 million 
used to purchase Norfolk Power Inc. (Norfolk Power) in 2014. See 
section “Capital Investments” for details of the Company’s capital 
investments, and section “Other Developments – Acquisitions” for 
details of the acquisitions of Haldimand Hydro and Woodstock 
Hydro.

Liquidity and Financing Strategy 

Short-term liquidity is provided through funds from operations, Hydro 
One Inc.’s Commercial Paper Program, and the Company’s 
consolidated credit facilities. Under the commercial paper program, 
Hydro One Inc. is authorized to issue up to $1.5 billion in short-term 
notes with a term to maturity of less than 365 days. At December 31, 
2015, Hydro One Inc. had $1,491 million in commercial paper 
borrowings outstanding, compared to no commercial paper 
borrowings outstanding at December 31, 2014. In addition, the 
Company and Hydro One Inc. have revolving credit facilities totalling 
$2,550 million that mature between 2018 and 2020. The 
Company may use the credit facilities for working capital and 
general corporate purposes. The short-term liquidity under the 
Commercial Paper Program, the credit facilities and anticipated levels 
of funds from operations are expected to be sufficient to fund the 
Company’s normal operating requirements. 

At December 31, 2015, all of the Company’s long-term debt 
totalling $8,723 million was issued by Hydro One Inc. under Hydro 
One Inc.’s MTN Program. At December 31, 2015, the maximum 
authorized principal amount of medium-term notes issuable under the 
MTN Program was $3.5 billion, with the entire amount remaining 
available until January 2018. The long-term debt consists of notes 
and debentures that mature between 2016 and 2064, and at 
December 31, 2015, had an average term to maturity of 
approximately 16.6 years and a weighted average coupon of 4.7%. 

At December 31, 2015, Hydro One’s corporate credit ratings from approved rating organizations were as follows: 

Rating Agency 

Standard & Poor’s Rating Services (S&P)1 

1  On September 18, 2015, S&P assigned its A corporate credit rating on Hydro One. The outlook is stable.

2	  On November 5, 2015, Moody’s downgraded the senior unsecured ratings of Hydro One Inc. to A3 from A2, downgraded its short term debt rating to 

Prime-2 from Prime-1, and revised its outlook on the Company to stable from negative. 

3  On September 18, 2015, S&P affirmed its ratings on Hydro One Inc., including its A long-term corporate credit rating on the company. 

At December 31, 2015, Hydro One and Hydro One Inc. were in 
compliance with all financial covenants and limitations associated 
with the outstanding borrowings and credit facilities. 

plan assets, rate of cost of living increase, and mortality assumptions. 
A full discussion of the significant assumptions and estimates can be 
found in the section “Critical Accounting Estimates – Employee Future 
Benefits.” 

Effect of Interest Rates 

The Company is exposed to fluctuations in interest rates as its 
regulated return on equity is derived using a formulaic approach that 
takes into account anticipated interest rates. See section “Risk 
Management and Risk Factors – Risks Relating to Hydro One’s 
Business – Market, Financial Instrument and Credit Risk” for more 
details. 

Pension Plan 

In 2015, Hydro One contributed approximately $177 million to its 
pension plan, compared to contributions of approximately 
$174 million in 2014, and incurred $163 million in net periodic 
pension benefit costs, compared to $158 million incurred in 2014. 
The Company estimates that total pension contributions for 2016 will 
be approximately $180 million. 

The Company’s pension benefits obligation is impacted by various 
assumptions and estimates, such as discount rate, rate of return on 

Capital Investments 

The Company makes capital investments to maintain the safety, 
reliability and integrity of its transmission and distribution assets and to 
provide for the ongoing growth and modernization required to meet 
the expanding and evolving needs of its customers and the electricity 
market. This is achieved through a combination of sustaining capital 
investments, which are required to support the continued operation of 
Hydro One’s existing assets, and development capital investments, 
which involve both additions to existing assets and large scale 
projects such as new transmission lines and transmission stations. 

In 2015, the Company made capital investments totalling 
$1,663 million and placed $1,476 million of new assets in-service, 
including replacements of end-of-life wood poles, new load 
connections, and the completion of two transformer replacements at 
the Hanmer Transmission Station, compared to $1,530 million of 
capital investments and $1,574 million of new assets placed in-
service in 2014.

Transmission Capital Investments 

The increase of $98 million or 11.6% in transmission capital 
investments in 2015 was primarily due to the following: 

•  several system re-investments, including various end-of-life 

equipment replacements at certain transmission stations, including 
the Bruce, Richview, Larchwood and Wiltshire Transmission 
Stations, as well as the completion of two transformer 
replacements at the Hanmer Transmission Station; 

•  the continued work on some of the Company’s major inter-area 
network and local area supply projects, such as the Clarington 
Transmission Station and Guelph Area Transmission Refurbishment 
projects; 

•  increased work on overhead lines refurbishment and replacement 

projects and programs; 

•  increased volume of work related to station security upgrades to 
prevent unauthorized entry to stations and enhance safety, and 
increased cyber system replacements, including firewall 
infrastructure, auxiliary equipment and management software, to 
adhere to the NERC Cyber Security standards; and 

•  increased volume of demand equipment replacements, as well as 
spare transformer equipment purchases to ensure readiness for 
unplanned transformer replacements; partially offset by 

•  decreased expenditures related to underground lines system 

replacements, as the end-of-life underground transmission cables 
between the Strachan Transformer Station and Riverside Junction 
were replaced and placed in-service in 2014. 

Distribution Capital Investments 

The increase of $31 million or 4.6% in distribution capital investments 
in 2015 was primarily due to the following: 

•  increased capital lines work, primarily related to multiple 

sustainment initiatives programs and higher volume of component 
replacements; 

•  increased work related to station refurbishment programs due to a 
larger volume of transformer purchases and more refurbishments 
accomplished during 2015; and 

•  increased storm restoration work as a result of multiple wind storms 
which occurred during the fourth quarter of 2015, as well as 
related power quality-related issues; partially offset by 

•  decreased expenses in 2015 due to completion of a smart meter 

installation project in 2014.

1	  Contributions to the Hydro One Pension Fund are generally made one month in arrears. The 2016 minimum pension contributions are based on an actuarial 

valuation as at December 31, 2013 and projected levels of pensionable earnings. Pension contributions beyond 2016 are not estimable at this time. 

2	  Hydro One records a liability for the estimated future expenditures associated with the removal and destruction of polychlorinated biphenyl (PCB)­

contaminated insulating oils and related electrical equipment, and for the assessment and remediation of chemically-contaminated  lands owned by the 
Company. Hydro One also records a liability for asset retirement obligations associated with the removal and disposal of asbestos-containing materials 
installed in some of its facilities. The forecasted expenditure pattern reflects the Company’s planned work programs for the periods. 

3	  Inergi LP (Inergi), an affiliate of Capgemini Canada Inc., provides services to Hydro One, including settlements, source to pay services, pay operations 

services, information technology, finance and accounting services. The agreement with Inergi for these services expires in December 2019. In addition, Inergi 
provides customer service operations outsourcing services to Hydro One. The agreement for these services expires in February 2018. Brookfield Global 
Integrated Solutions (formerly Brookfield Johnson Controls Canada LP) (Brookfield) provides services to Hydro One, including facilities management and 
execution of certain capital projects as deemed required by the Company. The current agreement with Brookfield expires in December 2024. The contractual 
amounts disclosed include an estimated contractual annual inflation adjustment in the range of 1.9% to 2.1%. Payments in respect of the Company’s 
outsourcing agreements are recorded in OM&A costs on the Company’s Consolidated Statements of Operations and Comprehensive Income or as a cost of 
capital programs. 

4  The Company and Hydro One Inc. have revolving credit facilities totalling $2,550 million that expire between 2018 and 2020. 

5	  Hydro One Inc. currently has outstanding bank letters of credit of $139 million relating to retirement compensation arrangements. Hydro One Inc. provides 

prudential support to the IESO in the form of letters of credit, the amount of which is calculated based on forecasted monthly power consumption. At 
December 31, 2015, Hydro One Inc. has provided a letter of credit to the IESO in the amount of $15 million to meet its current prudential requirements. 
Hydro One Inc. has also provided prudential support to the IESO on behalf of its subsidiaries as required by the IESO’s Market Rules, using parental 
guarantees of $329 million, and on behalf of a distributor using total guarantees of $1 million. 

Regulation	 

The OEB approves both the revenue requirements of and the rates 
charged by Hydro One’s regulated transmission and distribution 
businesses. The rates are designed to permit the Company’s 
transmission and distribution businesses to recover the allowed costs 

and to earn a formula-based annual rate of return on its equity 
invested in the regulated businesses. This is done by applying a 
specified equity risk premium to forecasted interest rates on long-term 
bonds. In addition, the OEB approves rate riders to allow for the 
recovery or disposition of specific regulatory deferral accounts over 
specified timeframes.

Hydro One Networks 

B2M LP 

Hydro One Networks’ transmission 2016 revenue requirement of 
$1,480 million is reflected in the Uniform Transmission Rates (UTR) 
Decision and Order. Hydro One Networks plans to submit a 
transmission application for 2017-2018 rates in the second quarter 
of 2016. 

The Hydro One Distribution forecast for 2017 will be subject to 
adjustments for cost of capital parameters. Hydro One Networks 
plans to submit a distribution application for 2018-2022 rates in the 
first quarter of 2017. 

26  ANNUAL REPORT 2015  HYDRO ONE LIMITED 

TSX: H 

On December 29, 2015, the OEB issued a Decision and Order 
approving the five-year revenue requirement for years 2015-2019 
inclusive, approving the recovery of $8 million start-up costs in rates, 
and the establishment of a deferral account to capture costs of Tax 
Rate and Rule changes. The January 14, 2016, Decision and Rate 
Order approved the B2M LP revenue requirement recovery through 
the 2016 UTRs.

Supply to Essex County Transmission 
Reinforcement Project 

On July 16, 2015, the OEB issued a Decision and Order granting 
Hydro One Networks Leave to Construct a new 13-kilometre 230 kV 
double-circuit transmission line in the Windsor-Essex region. The 
Decision and Order includes standard conditions of adherence to the 
system impact assessment and the connection impact assessment, 
and requires construction to commence within twelve months. In 
addition, on August 28, 2015, the OEB issued a letter stating that 
given the complexities and implications of the issues relating to cost 
allocation, including potential changes to the provisions in the 
Distribution System Code and the Transmission System Code, the 
OEB will not proceed with cost allocation through an adjudicative 
process, but will review these issues from a policy perspective. 

On January 7, 2016, the OEB initiated its policy review. In the 
southeast Essex County, a number of large distribution-connected 
customers are a factor driving the need for new transmission 
capacity, such as the new Leamington transmission station. Three 
other distributors embedded in Hydro One’s distribution area will also 
benefit from this investment. Therefore, Hydro One has proposed that 
its share of this transmission investment be shared proportionately 
between Hydro One and the other identified beneficiaries in the 
area. The OEB consultation will review the concept of proportional 
benefit and its application, as the policy and regulatory framework to 
flow transmission costs through to identified distribution-connected 
customers is not in place. 

Other Regulatory Developments 

Time-of-Use (TOU) Pricing Decision and Order 

On March 26, 2015, the OEB issued a Decision and Order to 
amend Hydro One Networks’ distribution license to include an 
exemption from the requirement to apply TOU pricing to 
approximately 170,000 Regulated Price Plan customers that are 
outside the smart meter telecommunications infrastructure. The 
exemption expires December 31, 2019. 

Distribution System Code Requirements 

In April 2015, the OEB introduced a Notice of Amendment to the 
Distribution System Code requiring electricity distributors to issue 
monthly bills to non-seasonal residential and certain general service 
customers by the end of 2016. In addition, the OEB amended the 
Distribution System Code imposing a 98% billing accuracy 
requirement, and provisions allowing a local distribution company to 
issue a bill based on estimated consumption only twice every twelve 
months to these customers. In September 2015, the OEB issued its 

Decision and Order amending Hydro One Networks’ electricity 
distribution licence to include an exemption from the requirement for 
estimated billing and billing accuracy for the 170,000 hard-to-reach 
customers that are currently exempt from TOU billing, for a term 
ending on December 31, 2019. 

On December 31, 2015, Hydro One submitted a report to the OEB 
summarizing that as of November 2015, approximately only 
101,000 “hard-to-reach” customers received estimated bills in 2015 
and significant improvements were realized in estimated billing 
accuracy due to the availability of better customer-specific historical 
usage data on which the estimation algorithms are based.

Conservation and Demand Management 

In accordance with a directive from the Minister of Energy and 
Infrastructure dated March 31, 2010, as a condition of licence, 
certain licensed electricity distributors must meet the IESO established 
targets for the reduction of electricity consumption and peak 
provincial electricity demand. On September 30, 2015, Hydro One 
Networks filed its annual Conservation and Demand Management 
(CDM) Report with the OEB. In 2014, Hydro One Networks 
achieved 167.4 MW in peak demand savings and 898.4 GWh in 
energy savings, which represent 78.4% and 79.5% of its peak 
demand and energy reduction targets, respectively. Although Hydro 
One Networks did not meet its peak demand reduction target, no 
punitive action will be taken against the Company. 

Rate Design (previously Revenue Decoupling for 
Distributors) 

In April 2015, the OEB issued a report, “Board Policy: A New 
Distribution Rate Design for Residential Electricity Customers”, outlining 
its new policy on fully fixed distribution charges for residential 
customers. The current distribution charges are a combination of fixed 
and variable rates. Under the new policy, electricity distributors will 
structure their residential rates such that all distribution service costs 
will be collected through a fixed monthly charge only. The new 
policy will be implemented gradually over a four year period, with 
increases in the fixed rate and decreases in the variable rate, 
resulting in a fixed rate only by 2019. The new rate design will 
enable residential customers to leverage new technologies, manage 
costs through conservation, and better understand the value of 
distribution services. It will also provide greater revenue stability for 
distributors, including Hydro One. 

In its December 22, 2015 Decision, the OEB has increased the 
transition period for Hydro One Networks’ certain customer classes to 
eight years to mitigate excessive bill impacts. 

TSX: H  HYDRO ONE LIMITED  ANNUAL REPORT 2015  27 

 
 
 
 
MANAGEMENT’S DISCUSSION AND ANALYSIS 

In January 2016, the OEB issued a Decision and Rate Order for the 
area formerly served by Norfolk Power approving Hydro One’s 
implementation plan to transition residential customers to fixed rates 
over a four year period. Although Norfolk Power customers’ rates are 
frozen for five years, the OEB Order approved Tariffs of Rates and 
Charges for 2016 only. 

In 2015, Hydro One Networks filed applications with the OEB with 
respect to the new rate design for residential customers in the service 
areas formerly served by Haldimand Hydro and Woodstock Hydro 
that include fixed rates for five years and implementation plans to 
transition to fixed distribution rates. Approvals for these applications 
are pending. 

Performance Measurement for Electricity 
Distributors 

On September 18, 2015, Hydro One Networks submitted its 2014 
Performance Scorecard to the OEB. In addition to ongoing 
operations, a major focus in 2014 was investing in improvements to 
the Company’s customer call centre and billing operations. Hydro 
One plans to continue developing targeted products and services that 
respond to its customers’ unique needs, including realizing value from 
the new customer information system, simplifying and shortening 
timeframes for the delivery of services, and enhancing accessibility to 
allow effective self-service for simple transactions. The Company is 
also committed to delivering programs to help its customers manage 
their energy consumption. Hydro One Networks’ 2014 Scorecard 
was posted on the Hydro One and the OEB websites. 

Renewed Regulatory Framework for Transmitters 

In 2015, the OEB initiated a discussion to develop a framework for 
the application of Renewed Regulatory Framework principles to 
transmitters, and in January 2016, issued a new set of draft filing 
requirements for transmitters for discussion. 

Transmitter Consolidations 

On January 19, 2016, the OEB issued the Handbook for Electricity 
Distributor and Transmitter Consolidations (the “handbook”) to provide 
guidance on applications for approval of electricity utility 
consolidations by way of mergers, acquisitions, amalgamations and 
divestitures and subsequent rate applications. The handbook is 
intended to provide guidance on the process for review of 
consolidation applications by the OEB and affirms the OEB’s policy 
of using the “no harm” test in reviewing consolidation applications. 

28  ANNUAL REPORT 2015  HYDRO ONE LIMITED 

TSX: H 

This test requires applicants to demonstrate that the costs to serve 
acquired customers post-consolidation will be no higher than they 
otherwise would be without consolidation. In addition the OEB will 
consider whether any price premium paid on the acquisition is 
financially burdensome to the applicant, as any premium paid over 
historic asset value is not recoverable in rates. The handbook will 
allow applicants to defer rebasing of the acquired utility for up to a 
10 year period with the view of permitting the applicant to fully 
realize the anticipated efficiency gains and offset the overall costs of 
the transaction. 

Other Developments 

Change in Hydro One Ownership Structure 

During the fourth quarter of 2015, Hydro One and Hydro One Inc. 
completed a series of Pre-Closing Transactions that resulted in, 
among other things, the acquisition by Hydro One of all of the issued 
and outstanding shares of Hydro One Inc. and the issuance of new 
common shares and preferred shares of Hydro One to the Province. 
On November 5, 2015, Hydro One and the Province concluded the 
IPO of Hydro One on the Toronto Stock Exchange, whereby 
81.1 million of the 595 million outstanding common shares of Hydro 
One were sold to the public. On November 12, 2015, the 
underwriters of the IPO exercised their option to purchase an 
additional 8.15 million common shares of Hydro One from the 
Province. All proceeds from the IPO were received by the Province. 
All of the regulated business and outstanding notes and debentures of 
Hydro One at the time of the IPO remain at Hydro One Inc. The final 
prospectus associated with the IPO, which contains details of the 
IPO, recapitalization and corporate structure, is posted on 
www.sedar.com. 

PILs Deemed Disposition Rules 

In connection with the IPO, upon ceasing to be exempt from tax 
under the Federal Tax Regime in October 2015, Hydro One and its 
subsidiaries were deemed to dispose of their assets for proceeds 
equal to their fair market value, triggering a PILs liability of $2.6 
billion (Departure Tax). The Departure Tax amount was confirmed in 
writing by the Minister of Finance and was paid to the OEFC in 
2015. To enable Hydro One and its subsidiaries to pay the 
Departure Tax, the Province made an equity injection of $2.6 billion 
in Hydro One and received 2.6 billion common shares of Hydro 
One. The revaluation of the tax basis of the assets of Hydro One Inc. 
and its subsidiaries to fair market value resulted in a net deferred tax 
recovery of $2,619 million recorded in 2015.

Class Action Lawsuit 

Acquisition of Woodstock Hydro 

In September 2015, Hydro One and three of its subsidiaries were 
served with a class action suit in which the representative plaintiff is 
seeking up to $125 million in damages related to allegations of 
improper billing practices. Hydro One intends to defend the action. 
Due to the preliminary stage of legal proceedings, an estimate of a 
possible loss related to this claim cannot be made. 

Acquisitions 

Integration of Norfolk Power 

The Company acquired Norfolk Power in August 2014. The 
purchase price for Norfolk Power, adjusted for working capital and 
other closing adjustments, was approximately $68 million. Due to this 
acquisition, approximately 18,000 new customers were added to 
Hydro One’s Distribution Business. In September 2015, the 
Company completed the integration of Norfolk Power, including the 
integration of employees, customers, business processes, information 
and operations. This successful integration will allow the Company to 
standardize processes and leverage key lessons learned to drive 
efficiency and improvements when integrating other acquisitions in the 
future. 

Acquisition of Haldimand Hydro 

In June 2015, Hydro One completed the acquisition of Haldimand 
Hydro, an electricity distribution company located in southwestern 
Ontario, following approval of the acquisition by the OEB in March 
2015. The purchase price for Haldimand Hydro, adjusted for 
working capital and other closing adjustments of approximately 
$8 million, was approximately $73 million. The goodwill of 
approximately $33 million arising from the Haldimand Hydro 
acquisition consists largely of the synergies and economies of scale 
expected from combining the operations of Hydro One and 
Haldimand Hydro. Due to this acquisition, approximately 
21,000 new customers were added to Hydro One’s Distribution 
Business. Integration of Haldimand Hydro is ongoing.

In October 2015, Hydro One completed the acquisition of 
Woodstock Hydro, an electricity distribution company located in 
southwestern Ontario, following approval of the acquisition by the 
OEB in September 2015. The purchase price for Woodstock Hydro, 
adjusted for preliminary working capital and other closing 
adjustments, was approximately $32 million. The preliminary 
goodwill of approximately $17 million arising from the Woodstock 
Hydro acquisition consists largely of the synergies and economies 
of scale expected from combining the operations of Hydro One 
and Woodstock Hydro. Due to this acquisition, approximately 
16,000 new customers were added to Hydro One’s Distribution 
Business. Integration of Woodstock Hydro is ongoing. 

Great Lakes Power Transmission Purchase 
Agreement 

On January 28, 2016, Hydro One reached an agreement to 
acquire from Brookfield Infrastructure various entities that own and 
control Great Lakes Power Transmission LP, an Ontario regulated 
electricity transmission business operating along the eastern shore of 
Lake Superior, north and east of Sault Ste. Marie, Ontario, for 
$222 million in cash, subject to customary adjustments, plus the 
assumption of approximately $151 million in outstanding 
indebtedness. The acquisition is pending a Competition Act approval 
as well as regulatory approval from the OEB. 

Hydro One Workforce 

Hydro One has a skilled and flexible work force of over 
5,500 regular employees and over 2,000 non-regular employees 
province-wide, comprising a mix of skilled trades, lines staff, 
engineering, professional, managerial and executive personnel. 
Hydro One’s regular employees are supplemented primarily by 
accessing a large external labour force available through 
arrangements with the Company’s trade unions for variable workers, 
sometimes referred to as “hiring halls”, and also by access to contract 
personnel. The hiring halls offer Hydro One the ability to access 
highly trained and appropriately skilled workers on a project-by­
project and seasonal basis.

Share-based Compensation 
Share Grant Plans 

At December 31, 2015, Hydro One had two share grant plans, one 
for the benefit of certain members of the Power Workers’ Union (the 
PWU Share Grant Plan) and one for the benefit of certain members 
of The Society of Energy Professionals (the Society Share Grant Plan). 

The PWU Share Grant Plan provides for the issuance of common 
shares of Hydro One from treasury to certain eligible members of the 
PWU annually, commencing on April 1, 2017 and continuing until 
the earlier of April 1, 2028 or the date an eligible employee no 
longer meets the eligibility criteria of the PWU Share Grant Plan. The 
number of common shares granted annually to each eligible 
employee will be equal to 2.7% of such eligible employee’s salary as 
at April 1, 2015, divided by the price of the common shares of 
Hydro One in the IPO. The aggregate number of common shares 
issuable under the PWU Share Grant Plan shall not exceed 
3,981,763 common shares. 

The Society Share Grant Plan provides for the issuance of common 
shares of Hydro One from treasury to certain eligible members of the 
Society annually, commencing on April 1, 2018 and continuing until 
the earlier of April 1, 2029 or the date an eligible employee no 
longer meets the eligibility criteria of the Society Share Grant Plan. 
The number of common shares granted annually to each eligible 
employee will be equal to 2.0% of such eligible employee’s salary as 
at September 1, 2015, divided by the price of the common shares 
of Hydro One in the IPO. The aggregate number of common shares 
issuable under the Society Share Grant Plan shall not exceed 
1,434,686 common shares.

Directors’ Deferred Share Unit (DSU) Plan 

The Province 

Under the Company’s Directors’ DSU Plan, directors can elect to 
receive credit for their annual cash retainer in a notional account of 
DSUs in lieu of cash. Hydro One’s Board of Directors may also 
determine from time to time that special circumstances exist that would 
reasonably justify the grant of DSUs to a director as compensation in 
addition to any regular retainer or fee to which the director is entitled. 

Employee Share Ownership Plan 

Effective December 15, 2015, Hydro One established an Employee 
Share Ownership Plan (ESOP). Under the ESOP, certain eligible 
management and non-represented employees may contribute 
between 1% and 6% of their base salary towards purchasing 
common shares of Hydro One. The Company will match 50% of the 
employee’s contributions, up to maximum Company contribution of 
$25,000 per calendar year. No contributions were made under the 
ESOP during 2015. 

Long-term Incentive Plan 

The Board of Directors of Hydro One adopted a Long-term Incentive 
Plan effective August 31, 2015. Under the Long-term Incentive Plan, 
long-term incentives will be granted to certain executive and 
management employees, and all equity-based awards will be settled 
in newly-issued shares of Hydro One from treasury, consistent with the 
provisions of the plan. 

The mix of long-term incentive vehicles has not yet been determined 
and, accordingly, the Long-term Incentive Plan provides flexibility to 
award a range of vehicles, including restricted share units, 
performance share units, stock options, share appreciation rights, 
restricted shares, deferred share units and other share-based awards. 
The mix of vehicles is intended to vary by role to recognize the level 
of executive accountability for overall business performance. It is 
expected that the specific incentive vehicles and performance targets 
associated with the Long-term Incentive Plan will be decided in early 
2016, after which the incentive grants will commence. No long-term 
incentive payments were awarded during 2015. 

Related Party Transactions 
The Province is the majority shareholder of Hydro One. The OEFC, 
IESO, Ontario Power Generation Inc. (OPG), the OEB, and Hydro 
One Brampton are related parties to Hydro One because they are 
controlled or significantly influenced by the Province. The following is 
a summary of the Company’s related party transactions during the 
year ended December 31, 2015: 

•  During 2015, Hydro One paid dividends to the Province totalling 
$888 million (2014 – $287 million). In addition, on August 31, 
2015, Hydro One declared a dividend in-kind on its common 
shares payable in all of the issued and outstanding shares of 
Hydro One Brampton. 

•  On November 4, 2015, Hydro One issued 2.6 billion common 

shares to the Province for proceeds of $2.6 billion. 

•  In 2015, Hydro One Inc. incurred certain IPO related expenses 
totaling $7 million which will be reimbursed to the Company by 
the Province and reimbursed by the Company to Hydro One Inc.

Risk Management and Risk Factors 
Risks Relating to Hydro One’s Business 
Regulatory Risks and Risks Relating to Hydro 
One’s Revenues 
Risks Relating to Obtaining Rate Orders 

The Company is subject to the risk that the OEB will not approve the 
Company’s transmission and distribution revenue requirements 
requested in future applications for rates. Rate applications for 
revenue requirements are subject to the OEB’s review process, usually 
involving participation from intervenors and a public hearing process. 
There can be no assurance that resulting decisions or rate orders 
issued by the OEB will permit Hydro One to recover all costs actually 
incurred, including operations, maintenance and administration costs, 
costs accumulated in other regulatory accounts (including, for 
instance, deferral and variance accounts), costs of debt and income 
taxes, or to earn a particular return on equity. A failure to obtain 
acceptable rate orders, or approvals of appropriate returns on equity 
and costs actually incurred, may materially adversely affect: Hydro 
One’s transmission or distribution businesses, the undertaking or 
timing of capital expenditures, ratings assigned by credit rating 
agencies, the cost and issuance of long-term debt, and other matters, 
any of which may in turn have a material adverse effect on the 
Company. In addition, there is no assurance that the Company will 
receive regulatory decisions in a timely manner and, therefore, costs 
may be incurred prior to having an approved revenue requirement. 

Risks Relating to Actual Performance Against 
Forecasts 

The Company’s ability to recover the actual costs of providing service 
and earn the allowed return on equity depends on the Company 
achieving its forecasts established and approved in the rate-setting 
process. Actual costs could exceed the approved forecasts if, for 
example, the Company incurs operations, maintenance and 
administration costs above those included in the Company’s 
approved revenue requirement, higher capital expenditures than 
those approved in rate decisions, or additional financing charges 
because of increased debt amounts or higher interest rates. The 
inability to obtain acceptable rate decisions or to otherwise recover 
any significant difference between forecast and actual expenses 
could materially adversely affect the Company’s financial condition 
and results of operations. 

Further, the OEB approves the Company’s transmission and distribution 
rates based on projected electricity load and consumption levels, among 
other factors. If actual load or consumption materially falls below 
projected levels, the Company’s revenue and net income for either, or

I

both, of these businesses could be materially adversely affected. Also, 
the Company’s current revenue requirements for these businesses are 
based on cost and other assumptions that may not materialize. There is 
no assurance that the OEB would allow rate increases sufficient to offset 
unfavourable financial impacts from unanticipated changes in electricity 
demand or in the Company’s costs. 

The Company is subject to risk of revenue loss from other factors, 
such as economic trends and weather conditions that influence the 
demand for electricity. The Company’s overall operating results may 
fluctuate substantially on a seasonal and year-to-year basis based on 
these trends and weather conditions. For instance, a cooler than 
normal summer or warmer than normal winter may reduce demand 
for electricity below that forecast by the Company, causing a 
decrease in the Company’s revenues from the same period of the 
previous year. The Company’s load could also be negatively 
affected by successful CDM programs whose results exceed 
forecasted expectations. 

Risks Relating to Rate-Setting Models for 
Transmission and Distribution 

The OEB’s rate-setting model for distributors requires that the term of a 
custom rate application (distribution business) be a minimum five-year 
period. There are risks associated with forecasting over such a long 
period. For instance, if unanticipated capital expenditures arise that 
were not contemplated in the Company’s most recent rate decision, 
the Company may be required to incur costs that may not be 
recoverable until a future period or not recoverable at all in future 
rates. This could have a material adverse effect on the Company. 

The OEB has stated its intention to examine the policies that may 
apply to transmission rate setting, and this may result in changes to 
the rate-setting model for transmission services. A change to the rate-
setting model for transmission services, such as the introduction of an 
asymmetrical earnings sharing mechanism, could result in a decrease 
in the Company’s revenues or financial performance. 

The OEB approves and periodically, generally on an annual basis, 
changes the return on equity for transmission and distribution 
businesses. The OEB may in the future decide to reduce its allowed 
return on equity for either of these businesses, modify the formula or 
methodology it uses to determine the return on equity, or reduce the 
weighting of the equity component of the deemed capital structure. 
Any such reduction could reduce the net income of the Company. 

Risks Relating to Capital Expenditures 

In order to be recoverable, capital expenditures require the approval 
of the OEB, either through the approval of capital expenditure plans, 
rate base or revenue requirements for the purposes of setting 

A

D

I

transmission and distribution rates, which include the impact of capital 
expenditures on rate base or cost of service. There can be no 
assurance that all capital expenditures incurred by Hydro One will be 
approved by the OEB. Capital cost overruns may not be recoverable 
in transmission or distribution rates. The Company could incur 
unexpected capital expenditures in maintaining or improving its 
assets, particularly given that new technology is required to support 
renewable generation and unforeseen technical issues may be 
identified through implementation of projects. There is risk that the 
OEB may not allow full recovery of such expenditures in the future. To 
the extent possible, Hydro One aims to mitigate this risk by ensuring 
prudent expenditures, seeking from the regulator clear policy direction 
on cost responsibility, and pre-approval of the need for capital 
expenditures. 

While the Company expects all of its expenditures and regulatory 
assets to be fully recoverable after OEB review, any future regulatory 
decision to disallow or limit the recovery of such costs would lead to 
a lower than expected approved revenue requirement or rate base, 
potential asset impairment or charges to the Company’s results of 
operations, any of which could have a material adverse effect on the 
Company. 

Risks Relating to Deferred Tax Asset 

As a result of leaving the PILs Regime and entering the Federal Tax 
Regime, Hydro One recorded a deferred tax asset due to the 
revaluation of the tax basis of Hydro One’s fixed assets at their fair 
market value and recognition of eligible capital expenditures. 
Management believes this will result in annual net cash savings over 
the next five years due to the reduction of cash taxes payable by 
Hydro One associated primarily with a higher capital cost 
allowance. There is a risk that, in future rate applications, the OEB 
will reduce the Company’s revenue requirement by all or a portion of 
those net cash savings. If the OEB were to reduce the Company’s 
revenue requirement in this manner, it could have a material adverse 
effect on the Company. 

Risks Relating to Other Applications to the OEB 

The Company is also subject to the risk that it will not obtain required 
regulatory approvals for other matters, such as leave to construct 
applications, applications for mergers, acquisitions, amalgamations 
and divestitures, and environmental approvals. Decisions to acquire 
or divest other regulated businesses licensed by the OEB are subject 
to OEB approval. Accordingly, there is the risk that such matters may 
not be approved or that unfavourable conditions will be imposed by 
the OEB.

MANAGEMENT’S DISCUSSION AND ANALYSIS 

First Nations and Métis Claims Risk 

Some of the Company’s current and proposed transmission and 
distribution assets are or may be located on Reserve (as defined in 
the Indian Act (Canada)) lands, and lands over which First Nations 
and Métis have Aboriginal, treaty or other legal claims. Although the 
Company has a recent history of successful negotiations and 
engagement with First Nations and Métis communities in Ontario, 
some First Nations and Métis leaders, communities and their 
members have made assertions related to sovereignty and jurisdiction 
over Reserve lands and traditional territories and are increasingly 
willing to assert their claims through the courts, tribunals, or by direct 
action. These claims could have a material adverse effect on the 
Company or otherwise materially adversely impact the Company’s 
operations, including the development of current and future projects. 

The Company’s operations and activities may, on occasion, give rise 
to the Crown’s duty to consult and potentially accommodate First 
Nations and Métis communities. Procedural aspects of the duty to 
consult may be delegated to the Company by the Province or the 
federal government. A perceived failure by the Crown to sufficiently 
consult a First Nations or Métis community, or a perceived failure by 
the Company in relation to delegated consultation obligations, could 
result in legal challenges against the Crown or the Company, 
including judicial review or injunction proceedings, or could 
potentially result in direct action against the Company by a 
community or its members. If this occurs, it could disrupt or delay the 
Company’s operations and activities, including current and future 
projects, and have a material adverse effect on the Company. 

Risk from Transfer of Assets Located on Reserves 

The transfer orders by which the Company acquired certain of 
Ontario Hydro’s businesses as of April 1, 1999 did not transfer title 
to assets located on Reserves. The transfer of title to these assets did 
not occur because authorizations originally granted by the federal 
government for the construction and operation of these assets on 
Reserves could not be transferred without required consent. In several 
cases, the authorizations had either expired or had never been 
issued. 

Currently, the Ontario Electricity Financial Corporation holds legal title 
to these assets and it is expected that the Company will manage 
them until it has obtained permits to complete the title transfer. To 
occupy Reserves, the Company must have valid permits issued by 
Her Majesty the Queen in the Right of Canada. For each permit, the 
Company must negotiate an agreement (in the form of a 
memorandum of understanding) with the First Nation, the Ontario 
Electricity Financial Corporation and any members of the First Nation 
who have occupancy rights. The agreement includes provisions 
whereby the First Nation consents to the federal government (presently 

34  ANNUAL REPORT 2015  HYDRO ONE LIMITED 

TSX: H 

Indigenous Affairs and Northern Development Canada) issuing a 
permit. For transmission assets, the Company must negotiate terms of 
payment. It is difficult to predict the aggregate amount that the 
Company may have to pay, either on an annual or one-time basis, to 
obtain the required agreements from First Nations. If the Company 
cannot reach satisfactory agreements with the relevant First Nation to 
obtain federal permits, it may have to relocate these assets to other 
locations at a cost that could be substantial. In a limited number of 
cases, it may be necessary to abandon a line and replace it with 
diesel generation facilities. In either case, the costs relating to these 
assets could have a material adverse effect on the Company if the 
costs are not recoverable in future rate orders. 

Compliance with Laws and Regulations 

Hydro One must comply with numerous laws and regulations 
affecting its business, including requirements relating to transmission 
and distribution companies, environmental laws, employment laws 
and health and safety laws. The failure of the Company to comply 
with these laws could have a material adverse effect on the 
Company’s business. See also “– Health, Safety and Environmental 
Risk”. 

For instance, Hydro One’s licensed transmission and distribution 
businesses are required to comply with the terms of their licenses, with 
codes and rules issued by the OEB, and with other regulatory 
requirements, including regulations of the National Energy Board. In 
Ontario, the Market Rules issued by the IESO require the Company 
to, among other things, comply with the reliability standards 
established by the NERC and Northeast Power Coordinating 
Council, Inc. (NPCC). The incremental costs associated with 
compliance with these reliability standards are expected to be 
recovered through rates, but there can be no assurance that the OEB 
will approve the recovery of all of such incremental costs. Failure to 
obtain such approvals could have a material adverse effect on the 
Company. 

There is the risk that new legislation, regulations or policies will be 
introduced in the future. These may require Hydro One to incur 
additional costs, which may or may not be recovered in future 
transmission and distribution rates. 

Risk of Natural and Other Unexpected 
Occurrences 

The Company’s facilities are exposed to the effects of severe weather 
conditions, natural disasters, man-made events including but not 
limited to cyber and physical terrorist type attacks, events which 
originate from third party connected systems, or any other potentially 
catastrophic events. Although constructed, operated and maintained 
to industry standards, the Company’s facilities may not withstand

occurrences of this type in all circumstances. The Company does not 
have insurance for damage to its transmission and distribution wires, 
poles and towers located outside its transmission and distribution 
stations resulting from these or other events. Losses from lost revenues 
and repair costs could be substantial, especially for many of the 
Company’s facilities that are located in remote areas. The Company 
could also be subject to claims for damages caused by its failure to 
transmit or distribute electricity. Hydro One’s risk is partly mitigated 
because its transmission system is designed and operated to 
withstand the loss of any major element and possesses inherent 
redundancy that provides alternate means to deliver large amounts of 
power. In the event of a large uninsured loss, Hydro One would 
apply to the OEB for recovery of such loss; however, there can be no 
assurance that the OEB would approve any such applications, in 
whole or in part, which could have a material adverse effect on the 
Company. 

Risk Associated with Information Technology 
Infrastructure and Data Security 

The Company’s ability to operate effectively in the Ontario electricity 
market is, in part, dependent upon it developing, maintaining and 
managing complex information technology systems which are 
employed to operate and monitor its transmission and distribution 
facilities, financial and billing systems and other business systems. The 
Company’s increasing reliance on information systems and 
expanding data networks increases its exposure to information 
security threats. The Company’s transmission business is required to 
comply with various rules and standards for transmission reliability, 
including mandatory standards established by the NERC and the 
NPCC. These include standards relating to cyber-security and 
information technology, which only apply to certain of the Company’s 
assets (generally being those whose failure could impact the 
functioning of the bulk electricity system). The Company may maintain 
different or lower levels of information technology security for its assets 
that are not subject to these mandatory standards. Unauthorized 
access to corporate and information technology systems or cyber­
attacks could result in service disruptions and system failures, which 
could have a material adverse effect on the Company, including as a 
result of a failure to provide electricity to customers. In addition, in the 
normal course of its operations, the Company may collect, process or 
retain access to confidential customer, supplier, counterparty or 
employee information, which could be exposed in the event of a 
cyber security incident. 

Hydro One mitigates these risks, including through the use of security 
event management tools on its power and business systems, by 
separating its transmission and distribution system networks from its 
other business system networks, by performing scans of its systems for 
known cyber threats and by providing company-wide awareness 
training to Hydro One personnel. Hydro One also engages the 

services of external experts to evaluate the security of its information 
technology infrastructure and controls. Hydro One performs 
vulnerability assessments on its critical cyber assets and it ensures 
security and privacy controls are incorporated into new information 
technology capabilities. Although these security and system disaster 
recovery controls are in place, there can be no assurance that there 
will not be system failures or security breaches or that such threats 
would be detected or mitigated on a timely basis. Upon occurrence 
and detection, the focus would shift from prevention to isolation, 
remediation and recovery until the incident has been fully addressed. 
Any such system failures or security breaches could have a material 
adverse effect on the Company.

Workforce Demographic Risk 

By the end of 2015, approximately 17% of the Company’s 
employees were eligible for retirement and by the end of 2016, up 
to approximately 21% could be eligible. These percentages are not 
evenly spread across the Company’s workforce, but tend to be most 
significant in the most senior levels of the Company’s staff and 
especially among management staff. During each of 2015 and 
2014, approximately 3% of the Company’s workforce elected to 
retire. Accordingly, the Company’s continued success will be tied to 
its ability to attract and retain sufficient qualified staff to replace the 
capability lost through retirements and to meet the demands of the 
Company’s work programs. 

In addition, the Company expects the skilled labour market for its 
industry to be highly competitive in the future. Many of the 
Company’s current employees and many of the potential employees it 
would seek in the future possess skills and experience that would also 
be highly sought after by other organizations inside and outside the 
electricity sector. The failure to attract and retain qualified personnel 
for Hydro One’s business could have a material adverse effect on the 
Company. 

Labour Relations Risk 

The substantial majority of the Company’s employees are represented 
by either the Power Workers’ Union or The Society of Energy 
Professionals. Over the past several years, significant effort has been 
expended to increase Hydro One’s flexibility to conduct operations in 
a more cost efficient manner. Although the Company has achieved 
improved flexibility in its collective agreements, the Company may not 
be able to achieve further improvements. The Company recently 
reached an agreement with the Power Workers’ Union for a renewal 
collective agreement with a three-year term, covering the period from 
April 1, 2015 to March 31, 2018 and an early renewal collective 
agreement with The Society of Energy Professionals with a three-year 
term, covering the period from April 1, 2016 to March 31, 2019. 
The Company also reached a renewal collective agreement with the 

TSX: H  HYDRO ONE LIMITED  ANNUAL REPORT 2015  35 

 
 
 
 
MANAGEMENT’S DISCUSSION AND ANALYSIS 

Canadian Union of Skilled Workers for a three-year term, covering 
the period from May 1, 2014 to April 30, 2017. Additionally, the 
Electrical Power Systems Construction Association (“EPSCA”) and a 
number of construction unions have reached renewal agreements, to 
which Hydro One is bound, for a 5-year period covering May 1, 
2015 to April 30, 2020. However, there can be no assurance that 
future collective agreement renewals with these unions or that 
collective agreements with the other unions with which Hydro One 
has contractual relationships, will be renewed on acceptable terms. 
The Company faces financial risks related to its ability to negotiate 
collective agreements consistent with its rate orders. In addition, in the 
event of a labour dispute, the Company could face operational risk 
related to continued compliance with its license requirements of 
providing service to customers. Any of these could have a material 
adverse effect on the Company. 

Risk Associated with Arranging Debt Financing 
The Company expects to borrow to repay its existing indebtedness 
and to fund a portion of capital expenditures. Hydro One Inc. has 
substantial amounts of existing debt, including $500 million maturing 
in 2016, $600 million maturing in 2017, and $750 million 
maturing in 2018. In addition, from time to time, the Company may 
draw on its syndicated bank lines and or issue short-term debt under 
Hydro One Inc.’s $1.5 billion commercial paper program which 
would need to be paid down. The Company also plans to incur 
capital expenditures of over $1.6 billion for each of 2016 and 
2017. Cash generated from operations, after the payment of 
expected dividends, will not be sufficient to fund the repayment of the 
Company’s existing indebtedness and capital expenditures. The 
Company’s ability to arrange sufficient and cost-effective debt 
financing could be materially adversely affected by numerous factors, 
including the regulatory environment in Ontario, the Company’s 
results of operations and financial position, market conditions, the 
ratings assigned to its debt securities by credit rating agencies and 
general economic conditions. A downgrade in the Company’s credit 
ratings could restrict the Company’s ability to access debt capital 
markets and increase the Company’s cost of debt. Any failure or 
inability on the Company’s part to borrow the required amounts of 
debt on satisfactory terms could impair its ability to repay maturing 
debt, fund capital expenditures and meet other obligations and 
requirements and, as a result, could have a material adverse effect 
on the Company. 

Market, Financial Instrument and Credit Risk 
Market risk refers primarily to the risk of loss that results from changes 
in costs, foreign exchange rates and interest rates. The Company is 
exposed to fluctuations in interest rates as its regulated return on 
equity is derived using a formulaic approach that takes into account 
anticipated interest rates, but is not currently exposed to material 
commodity price risk or material foreign exchange risk. 

36  ANNUAL REPORT 2015  HYDRO ONE LIMITED 

TSX: H 

The OEB-approved adjustment formula for calculating return on equity 
in a deemed regulatory capital structure of 60% debt and 40% equity 
provides for increases and decreases depending on changes in 
benchmark rates of return for Government of Canada debt. The 
Company estimates that a 1% decrease in the forecasted long-term 
Government of Canada bond yield used in determining its rate of 
return would reduce the Company’s transmission business’ 2017 net 
income by approximately $22 million and its distribution business’ 
2017 net income by approximately $14 million. The Company’s net 
income is adversely impacted by rising interest rates as the 
Company’s maturing debt is refinanced at market rates. The 
Company periodically utilizes interest rate swap agreements to 
mitigate elements of interest rate risk. 

Financial assets create a risk that a counterparty will fail to discharge 
an obligation, causing a financial loss. Derivative financial 
instruments result in exposure to credit risk, since there is a risk of 
counterparty default. Hydro One monitors and minimizes credit risk 
through various techniques, including dealing with highly-rated 
counterparties, limiting total exposure levels with individual 
counterparties, entering into master agreements which enable net 
settlement, and by monitoring the financial condition of 
counterparties. The Company does not trade in any energy 
derivatives. Currently, there are no significant concentrations of credit 
risk with respect to any class of financial assets. The Company is 
required to procure electricity on behalf of competitive retailers and 
certain local distribution companies for resale to their customers. The 
resulting concentrations of credit risk are mitigated through the use of 
various security arrangements, including letters of credit, which are 
incorporated into the Company’s service agreements with these 
retailers in accordance with the OEB’s Retail Settlement Code. 

The failure to properly manage these risks could have a material 
adverse effect on the Company. 

Risks Relating to Asset Condition and Capital 
Projects 

The Company continually incurs sustainment and development capital 
expenditures and monitors the condition of its transmission assets to 
manage the risk of equipment failures and to determine the need for 
and timing of major refurbishments and replacements of its 
transmission and distribution infrastructure. However the lack of real 
time monitoring of distribution assets increases the risk of distribution 
equipment failure. The connection of large amounts of distributed 
generation on the distribution network has resulted in more equipment 
operations than in the past for the Company. This increases 
maintenance requirements and may accelerate the aging of the 
Company’s assets.

Execution of the Company’s capital expenditure programs, 
particularly for development capital expenditures, is partially 
dependent on external factors, such as environmental approvals, 
municipal permits, equipment outage schedules that accommodate 
the IESO, generators and transmission-connected customers, and 
supply chain availability for equipment suppliers and consulting 
services. There may also be a need for, among other things, 
Environmental Assessment Act (Ontario) approvals, approvals which 
require public meetings, appropriate engagement with First Nations 
and Métis communities, OEB approvals of expropriation or early 
access to property, and other activities. Obtaining approvals and 
carrying out these processes may also be impacted by opposition to 
the proposed site of the capital investments. Delays in obtaining 
required approvals or failure to complete capital projects on a timely 
basis could materially adversely affect transmission reliability or 
customers’ service quality or increase maintenance costs which could 
have a material adverse effect on the Company. External factors are 
considered in the Company’s planning process. However, if the 
Company is unable to carry out capital expenditure plans in a timely 
manner, equipment performance may degrade, which may reduce 
transmission capacity, compromise the reliability of the Company’s 
transmission system or increase the costs of operating and 
maintaining these assets. Any of these consequences could have a 
material adverse effect on the Company. 

Increased competition for the development of large transmission 
projects and legislative changes relating to the selection of 
transmitters could impact the Company’s ability to expand its existing 
transmission system, which may have an adverse effect on the 
Company. To the extent that other parties are selected to construct, 
own and operate new transmission assets, the Company’s share of 
Ontario’s transmission network would be reduced. 

Health, Safety and Environmental Risk 

Hydro One’s health, safety and environmental management system is 
designed to ensure hazards and risks are identified and assessed, 
and controls are implemented to mitigate significant risks. This system 
includes a standing committee of the Board of Directors that has 
governance over health, safety and environmental matters. However, 
given the expansive territory that the Company’s system encompasses 
and the amount of equipment that it owns, the Company cannot 
guarantee that all such risks will be identified and mitigated without 
significant cost and expense to the Company. The following are 
some of the areas that may have a significant impact on the 
Company’s operations. 

The Company is subject to extensive Canadian federal, provincial 
and municipal environmental regulation. Failure to comply could 
subject the Company to fines or other penalties. In addition, the 
presence or release of hazardous or other harmful substances could 

lead to claims by third parties or governmental orders requiring the 
Company to take specific actions such as investigating, controlling 
and remediating the effects of these substances. Hydro One currently 
has a voluntary land assessment and remediation program for off-site 
migration in place to identify and, where necessary, remediate 
historical contamination that has resulted from past operational 
practices and uses of certain long-lasting chemicals at the Company’s 
facilities. Any contamination of the Company’s properties could limit 
its ability to sell or lease these assets in the future.

In addition, actual future environmental expenditures may vary 
materially from the estimates used in the calculation of the 
environmental liabilities on the Company’s balance sheet. The 
Company does not have insurance coverage for these environmental 
expenditures. 

There is also risk associated with obtaining governmental approvals, 
permits, or renewals of existing approvals and permits related to 
constructing or operating facilities. This may require environmental 
assessment or result in the imposition of conditions, or both, which 
could result in delays and cost increases. 

Although Hydro One is not a large emitter of greenhouse gases, the 
Company monitors all of these emissions and has a management 
plan in place to track and report on all sources, including sulphur 
hexafluoride or “SF6”. In addition, the Company recognizes the risks 
associated with potential climate change and has developed plans to 
respond as appropriate. 

The Company anticipates that all of its future environmental 
expenditures will continue to be recoverable in future rates. However, 
any future regulatory decision to disallow or limit the recovery of such 
costs could have a material adverse effect on the Company. 

Pension Plan Risk 

Hydro One has the Hydro One Defined Benefit Pension Plan in place 
for the majority of its employees. Contributions to the pension plan 
are established by actuarial valuations which are minimally required 
to be filed with the Financial Services Commission of Ontario on a 
triennial basis. The most recently filed valuation was prepared as at 
December 31, 2013, and was filed in June 2014, covering a three 
year period from 2014 to 2016. Hydro One contributed 
approximately $174 million in respect of 2014, approximately 
$177 million in respect of 2015, and is expected to contribute 
approximately $180 million by the end of 2016 to its pension plan 
to satisfy minimum funding requirements. Contributions beyond 2016 
are expected to continue to be significant; actual amounts will 
depend on investment returns, interest rates, changes in benefits and 
actuarial assumptions, and may include additional voluntary 
contributions by the Company from time to time. A determination by 

TSX: H  HYDRO ONE LIMITED  ANNUAL REPORT 2015  37 

 
 
 
 
MANAGEMENT’S DISCUSSION AND ANALYSIS 

the OEB that some of the Company’s pension expenditures are not 
recoverable through rates could have a material adverse effect on the 
Company, and this risk may be exacerbated if the amount of 
required pension contributions increases. 

The OEB has begun a consultation process that will examine 
pensions and other post-employment benefits in regulated utilities. 
See “– Other Post-Employment and Post-Retirement Benefits Risks”. The 
outcome of this consultation process is uncertain and the Company is 
unable to assess the impact of the potential changes stemming from 
the review at this time. 

Risk of Recoverability of Total Compensation 
Costs 

The Company manages all of its total compensation costs, including 
pension and other post-employment and post-retirement benefits, 
subject to restrictions and requirements imposed by the collective 
bargaining process. Should any element of total compensation costs 
be disallowed in whole or part by the OEB and not be recoverable 
from customers in rates, the costs could be material and could lead to 
changes to the Company’s results of operations and decrease net 
income, which could have a material adverse effect on the 
Company. 

Other Post-Employment and Post-Retirement 
Benefits Risks 

The Company provides other post-employment and post-retirement 
benefits, including workers compensation benefits and long-term 
disability benefits to qualifying employees. The OEB has begun a 
consultation process that will examine pensions and other post-
employment benefits in regulated utilities. The objectives of the 
consultation are to develop standard principles to guide the OEB’s 
review of pension and other post-employment and post-retirement 
benefits costs in the future, to establish specific information 
requirements for application and to establish appropriate regulatory 
mechanisms for cost recovery which can be applied consistently 
across the gas and electricity sectors for rate-regulated utilities. The 
outcome of this consultation process is uncertain and the Company is 
unable to assess the impact of the potential changes stemming from 
the review at this time. A determination that some of the Company’s 
post-employment and post-retirement benefit costs are not recoverable 
could have a material adverse effect on the Company. 

Risk Associated with Outsourcing Arrangements 

Consistent with Hydro One’s strategy of reducing operating costs, it 
has entered into an outsourcing arrangement with Inergi for the 
provision of back office services and call centre services. If the 
outsourcing arrangement or statements of work thereunder are 

38  ANNUAL REPORT 2015  HYDRO ONE LIMITED 

TSX: H 

terminated for any reason or expire before a new supplier is selected, 
the Company could be required to incur significant expenses to 
transfer to another service provider or insource, which could have a 
material adverse effect on the Company’s business, operating results, 
financial condition or prospects. 

Risk from Provincial Ownership of Transmission 
Corridors 

The Province owns some of the corridor lands underlying the 
Company’s transmission system. Although the Company has the 
statutory right to use these transmission corridors, the Company may 
be limited in its options to expand or operate its systems. Also, other 
uses of the transmission corridors by third parties in conjunction with 
the operation of the Company’s systems may increase safety or 
environmental risks, which could have a material adverse effect on 
the Company. 

Litigation Risks 

In the normal course of the Company’s operations, it may become 
involved in, be named as a party to or be the subject of, various 
legal proceedings, including regulatory proceedings, tax 
proceedings and legal actions, relating to actual or alleged violations 
of law, common law damages claims, personal injuries, property 
damage, property taxes, land rights, the environment and contract 
disputes. The outcome of outstanding, pending or future proceedings 
cannot be predicted with certainty and may be determined adversely 
to the Company, which could have a material adverse effect on the 
Company. Even if the Company prevails in any such legal 
proceeding, the proceedings could be costly and time-consuming 
and would divert the attention of management and key personnel 
from the Company’s business operations, which could adversely 
affect the Company. 

Risks Relating to the Company’s Relationship 
with the Province 
Ownership by the Province and Voting Power; 
Share Ownership Restrictions 

The Province currently owns approximately 84% of the common 
shares of Hydro One. The Electricity Act restricts the Province from 
selling voting securities of Hydro One (including common shares) of 
any class or series if it would own less than 40% of the outstanding 
number of voting securities of that class or series after the sale and in 
certain circumstances also requires the Province to take steps to 
maintain that level of ownership. Accordingly, the Province is 
expected to continue to maintain a significant ownership interest in 
voting securities of Hydro One for an indefinite period.

As a result of its significant ownership of the common shares of Hydro 
One, the Province has, and is expected indefinitely to have, the 
ability to determine or significantly influence the outcome of 
shareholder votes, subject to the restrictions in the governance 
agreement entered into between Hydro One and the Province dated 
November 5, 2015 (“Governance Agreement”; available on SEDAR 
at www.sedar.com). While, with respect to its ownership interest in 
Hydro One, the Province has agreed to engage in the business and 
affairs of Hydro One only as an investor and not as a manager, and 
has stated its intention to achieve its policy objectives through 
legislation and regulation as it would with respect to any other utility 
operating in Ontario, the Governance Agreement preserves the 
Province’s right to vote its common shares in its sole interest, which 
may not be aligned with the interests of the Company’s other 
shareholders. 

The share ownership restrictions in the Electricity Act (“Share 
Ownership Restrictions”) and the Province’s significant ownership of 
common shares of Hydro One together effectively prohibit one or 
more persons acting together from acquiring control of Hydro One. 
They also may limit or discourage transactions involving other 
fundamental changes to Hydro One and the ability of other 
shareholders to successfully contest the election of the directors 
proposed for election pursuant to the Governance Agreement. The 
Share Ownership Restrictions may also discourage trading in, and 
may limit the market for, the common shares and other voting 
securities. 

Continued Influence by the Province 
Despite the terms of the Governance Agreement in which the Province 
has agreed to engage in the business and affairs of the Company as 
an investor and not as a manager, there is a risk that the Province’s 
engagement in the business and affairs of the Company as an 
investor will be informed by its own policy objectives and may 
influence the conduct of the business and affairs of the Company in 
ways that may not be aligned with the interests of other shareholders. 

Nomination of Directors and Confirmation of 
Chief Executive Officer and Chair 
Although director nominees are required to be independent of both 
the Company and the Province pursuant to the Governance 
Agreement, there is a risk that the Province will nominate or confirm 
individuals who satisfy the independence requirements but who it 
considers are disposed to support and advance its policy objectives 
and give disproportionate weight to the Province’s interests in 
exercising their business judgment and balancing the interests of 
the stakeholders of Hydro One. This, combined with the fact certain 
matters require a two-thirds vote of the Board of Directors, could 
allow the Province to unduly influence certain Board actions 
such as confirmation of the Chair and confirmation of the Chief 
Executive Officer. 

Board Removal Rights 

Under the Governance Agreement, the Province has the right to 
withhold from voting in favour of all director nominees and has the 
right to seek to remove and replace the entire Board of Directors, 
including in each case its own director nominees but excluding the 
Chief Executive Officer and, at the Province’s discretion, the Chair. In 
exercising these rights in any particular circumstance, the Province is 
entitled to vote in its sole interest, which may not be aligned with the 
interests of other shareholders.

More Extensive Regulation 

Although under the Governance Agreement, the Province has agreed 
to engage in the business and affairs of Hydro One as an investor 
and not as a manager and has stated that its intention is to achieve 
its policy objectives through legislation and regulation as it would 
with respect to any other utility operating in Ontario, there is a risk 
that the Province will exercise its legislative and regulatory power to 
achieve policy objectives in a manner that has a material adverse 
effect on the Company. 

Prohibitions on Selling the Company’s 
Transmission or Distribution Business 

The Electricity Act prohibits the Company from selling all or 
substantially all of the business, property or assets related to its 
transmission system or distribution system that is regulated by the 
OEB. There is a risk that these prohibitions may limit the ability of the 
Company to engage in sale transactions involving a substantial 
portion of either system, even where such a transaction may 
otherwise be considered to provide substantial benefits to the 
Company and the holders of the common shares. 

Future Sales of Common Shares by the Province 

The Province has indicated that it currently intends to sell further 
common shares of Hydro One over time, until it holds approximately 
40% of the common shares, subject to the selling restrictions agreed 
with the Underwriters. The registration rights agreement between 
Hydro One and the Province dated November 5, 2015 (available 
on SEDAR at www.sedar.com) also grants the Province the right to 
request that Hydro One file one or more prospectuses and take other 
procedural steps to facilitate secondary offerings by the Province of 
the common shares of Hydro One. Future sales of common shares of 
Hydro One by the Province, or the perception that such sales could 
occur, may materially adversely affect market prices for these 
common shares and impede Hydro One’s ability to raise capital 
through the issuance of additional common shares, including the 
number of common shares that Hydro One may be able to sell at a 
particular time or the total proceeds that may be realized.

MANAGEMENT’S DISCUSSION AND ANALYSIS 

Limitations on Enforcing the Governance 
Agreement 

The Governance Agreement includes commitments by the Province 
restricting the exercise of its rights as a holder of voting securities, 
including with respect to the maximum number of directors that the 
Province may nominate and on how the Province will vote with 
respect to other director nominees. Hydro One’s ability to obtain an 
effective remedy against the Province, if the Province were not to 
comply with these commitments, is limited as a result of the 
Proceedings Against the Crown Act (Ontario). This legislation 
provides that the remedies of injunction and specific performance are 
not available against the Province, although a court may make an 
order declaratory of the rights of the parties, which may influence the 
Province’s actions. A remedy of damages would be available to 
Hydro One, but damages may not be an effective remedy, 
depending on the nature of the Province’s non-compliance with the 
Governance Agreement. 

Critical Accounting Estimates 
The preparation of Hydro One Consolidated Financial Statements 
requires the Company to make estimates and judgments that affect 
the reported amounts of assets, liabilities, revenues and costs, and 
related disclosures of contingencies. Hydro One bases its estimates 
and judgments on historical experience, current conditions and 
various other assumptions that are believed to be reasonable under 
the circumstances, the results of which form the basis for making 
judgments about the carrying values of assets and liabilities, as well 
as identifying and assessing the Company’s accounting treatment 
with respect to commitments and contingencies. Actual results may 
differ from these estimates and judgments. Hydro One has identified 
the following critical accounting estimates used in the preparation of 
its Consolidated Financial Statements: 

Revenues 

Distribution revenues are recognized on an accrual basis and include 
billed and unbilled revenues. Unbilled revenues are based on an 
estimate of electricity delivered determined by historical trends of 
consumption and are estimated at the end of each month. The 
unbilled revenue estimate is affected by energy consumption, 
weather, and changes in the composition of customer classes. 

Accounts Receivable and Allowance for 
Doubtful Accounts 

In 2015, the Company revised its method to estimate the unbilled 
accounts receivable based on new technology implemented to 
enhance the estimation process. This change has been accounted for 
on a prospective basis in the consolidated financial statements at 

40  ANNUAL REPORT 2015  HYDRO ONE LIMITED 

TSX: H 

December 31, 2015. At December 31, 2015, the change in 
estimate reduced unbilled accounts receivable by approximately 
$121 million, with a corresponding offset to various components of 
the retail settlement variance accounts (RSVA) regulatory asset. The 
change in estimate had no impact on 2015 revenues or net income. 

The allowance for doubtful accounts reflects the Company’s best 
estimate of losses on billed accounts receivable balances. The 
Company estimates the allowance for doubtful accounts on customer 
receivables by applying internally developed loss rates to the 
outstanding receivable balances by aging category. Loss rates 
applied to the accounts receivable balances are based on historical 
overdue balances, customer payments and write-offs. 

Regulatory Assets and Liabilities 

Hydro One’s regulatory assets represent certain amounts receivable 
from future electricity customers and costs that have been deferred for 
accounting purposes because it is probable that they will be 
recovered in future rates. The regulatory assets mainly include costs 
related to the pension benefit liability, deferred income tax liabilities, 
post-retirement and post-employment benefit liability, share-based 
compensation costs, and environmental liabilities. The Company’s 
regulatory liabilities represent certain amounts that are refundable to 
future electricity customers, and pertain primarily to OEB deferral and 
variance accounts. The regulatory assets and liabilities can be 
recognized for rate-setting and financial reporting purposes only if the 
amounts have been approved for inclusion in the electricity rates by 
the OEB, or if such approval is judged to be probable by 
management. If management judges that it is no longer probable that 
the OEB will allow the inclusion of a regulatory asset or liability in 
future electricity rates, the applicable carrying amount of the 
regulatory asset or liability will be reflected in results of operations in 
the period that the judgment is made by management. 

Environmental Liabilities 

Hydro One records a liability for the estimated future expenditures 
associated with the removal and destruction of PCB-contaminated 
insulating oils and related electrical equipment, and for the 
assessment and remediation of chemically-contaminated lands. There 
are uncertainties in estimating future environmental costs due to 
potential external events such as changes in legislation or regulations 
and advances in remediation technologies. In determining the 
amounts to be recorded as environmental liabilities, the Company 
estimates the current cost of completing required work and makes 
assumptions as to when the future expenditures will actually be 
incurred, in order to generate future cash flow information. All factors 
used in estimating the Company’s environmental liabilities represent 
management’s best estimates of the present value of costs required to

meet existing legislation or regulations. However, it is reasonably 
possible that numbers or volumes of contaminated assets, cost 
estimates to perform work, inflation assumptions and the assumed 
pattern of annual cash flows may differ significantly from the 
Company’s current assumptions. Environmental liabilities are 
reviewed annually or more frequently if significant changes in 
regulations or other relevant factors occur. Estimate changes are 
accounted for prospectively. 

Employee Future Benefits 

Hydro One’s employee future benefits consist of pension and post-
retirement and post-employment plans, and include pension, group 
life insurance, health care, and long-term disability benefits provided 
to the Company’s current and retired employees. Employee future 
benefits costs are included in Hydro One’s labour costs that are either 
charged to results of operations or capitalized as part of the cost of 
property, plant and equipment and intangible assets. Changes in 
assumptions affect the benefit obligation of the employee future 
benefits and the amounts that will be charged to results of operations 
or capitalized in future years. The following significant assumptions 
and estimates are used to determine employee future benefit costs 
and obligations: 

Weighted Average Discount Rate 

The weighted average discount rate used to calculate the employee 
future benefits obligation is determined at each year end by referring 
to the most recently available market interest rates based on “AA”­
rated corporate bond yields reflecting the duration of the applicable 
employee future benefit plan. The discount rate at December 31, 
2015 remained at 4.00% for pension benefits whereas it increased 
to 4.10% (from 4.00% used at December 31, 2014) for the post-
retirement and post-employment plans. The increase in the discount 
rate has resulted in a corresponding decrease in employee future 
benefits liabilities for the post-retirement and post-employment plans 
for accounting purposes. The liabilities are determined by 
independent actuaries using the projected benefit method prorated on 
service and based on assumptions that reflect management’s best 
estimates. 

Expected Rate of Return on Plan Assets 

The expected rate of return on pension plan assets is based on 
expectations of long-term rates of return at the beginning of the year 
and reflects a pension asset mix consistent with the pension plan’s 
current investment policy. 

Rates of return on the respective portfolios are determined with 
reference to respective published market indices. The expected rate 
of return on pension plan assets reflects the Company’s long-term 

expectations. We believe that this assumption is reasonable because, 
with the pension plan’s balanced investment approach, the higher 
volatility of equity investment returns is intended to be offset by the 
greater stability of fixed-income and short-term investment returns. The 
net result, on a long-term basis, is a lower return than might be 
expected by investing in equities alone. In the short term, the pension 
plan can experience fluctuations in actual rates of return.

Rate of Cost of Living Increase 

The rate of cost of living increase is determined by considering 
differences between long-term Government of Canada nominal 
bonds and real return bonds, which decreased from 1.70% per 
annum as at December 31, 2014 to approximately 1.50% per 
annum as at December 31, 2015. Given the Bank of Canada’s 
commitment to keep long-term inflation between 1.00% and 3.00%, 
management believes that the current rate is reasonable to use as a 
long-term assumption and as such, has used a 2.0% per annum 
inflation rate for employee future benefits liability valuation purposes 
as at December 31, 2015. 

Mortality Assumptions 

The Company’s employee future benefits liability is also impacted by 
changes in life expectancies used in mortality assumptions. Increases 
in life expectancies of plan members result in increases in the 
employee future benefits liability. The mortality assumption at 
December 31, 2015 is based on the final tables issued by the 
Canadian Institute of Actuaries (for public sector, with projection scale 
CPM-B and no adjustment due to pension size). This is the same 
assumption as was used as of December 31, 2014. 

Rate of Increase in Health Care Cost Trends 

The costs of post-retirement and post-employment benefits are 
determined at the beginning of the year and are based on 
assumptions for expected claims experience and future health care 
cost inflation. A 1% increase in the health care cost trends would 
result in a $22 million increase in 2015 interest cost plus service 
cost, and a $252 million increase in the year-end 2015 benefit 
liability. 

Asset Impairment 

Within Hydro One’s regulated businesses, the carrying costs of most 
of the long-lived assets are included in the rate base where they earn 
an OEB-approved rate of return. Asset carrying values and the related 
return are recovered through OEB-approved rates. As a result, such 
assets are only tested for impairment in the event that the OEB 
disallows recovery, in whole or in part, or if such a disallowance is 
judged to be probable. We regularly monitor the assets of the

legal entities. This update is applicable to Hydro One for the years 
and interim periods beginning on January 1, 2016. The Company 
does not anticipate that the adoption of this update will have a 
significant impact on its consolidated financial statements. 

Goodwill is evaluated for impairment on an annual basis, or more 
frequently if circumstances require. Hydro One has concluded that 
goodwill was not impaired at December 31, 2015. Goodwill 
represents the cost of acquired local distribution companies that is in 
excess of the fair value of the net identifiable assets acquired at the 
acquisition date. 

Disclosure Controls And Internal Controls 
Over Financial Reporting 

Internal controls have been documented and tested for adequacy and 
effectiveness, and continue to be refined over all business processes. 

In compliance with the requirements of National Instrument 52-109, 
the Company’s Certifying Officers have reviewed and certified the 
Consolidated Financial Statements for the year ended December 31, 
2015, together with other financial information included in the 
Company’s securities filings. The Certifying Officers have also 
certified that disclosure controls and procedures (DC&P) have been 
designed to provide reasonable assurance that material information 
relating to the Company is made known within the Company. Further, 
the Certifying Officers have certified that internal controls over 
financial reporting (ICFR) have been designed to provide reasonable 
assurance regarding the reliability of financial reporting and the 
preparation of the Consolidated Financial Statements. Based on the 
evaluation of the design and operating effectiveness of the 
Company’s DC&P and ICFR, the Certifying Officers concluded that 
the Company’s DC&P and ICFR were effective as at December 31, 
2015. 

New Accounting Pronouncements 

In January 2015, the Financial Accounting Standards Board (FASB) 
issued an accounting standards update that eliminates the 
requirements for reporting entities to consider whether an underlying 
event or transaction is extraordinary and to show the item separately 
in the income statement. This update is applicable to Hydro One for 
the years and interim periods beginning on January 1, 2016. The 
Company does not anticipate that the adoption of this update will 
have a significant impact on its consolidated financial statements. 

In February 2015, the FASB issued an accounting standards update 
that provides guidance about the analysis that a reporting entity must 
perform to determine whether it should consolidate certain types of 

42  ANNUAL REPORT 2015  HYDRO ONE LIMITED 

TSX: H 

In April 2015, the FASB issued an accounting standards update that 
requires debt issuance costs related to a recognized debt liability to 
be presented on the balance sheet as a direct deduction from the 
carrying amount of that debt liability. The recognition and 
measurement guidance for debt issuance costs are not affected. This 
update is applicable to Hydro One for the years and interim periods 
beginning on January 1, 2016. Upon adoption of this update in the 
first quarter of 2016, the Company’s deferred debt issuance costs 
that are currently presented under other long-term assets will be 
reclassified as a deduction from the carrying amount of long-term 
debt. 

In April 2015, the FASB issued an accounting standards update that 
permits an entity with a fiscal year-end that does not coincide with a 
month-end and an entity that has a significant event in an interim 
period that calls for a remeasurement of defined benefit plan assets 
and obligations to measure the defined benefit plan assets and 
obligations using the month-end that is closest to the entity’s fiscal 
year-end. This update is applicable to Hydro One for the years and 
interim periods beginning on January 1, 2016. The Company does 
not anticipate that the adoption of this update will have a significant 
impact on its consolidated financial statements. 

In April 2015, the FASB issued an accounting standards update that 
provides guidance to customers about whether a cloud computing 
arrangement includes a software license, as well as the related 
accounting for the arrangement. This update is applicable to Hydro 
One for the years and interim periods beginning on January 1, 
2016. The Company is currently assessing the impact of adoption of 
this update on its consolidated financial statements. 

In August 2015, the FASB issued an accounting standards update 
that defers by one year the effective date of a revenue recognition 
standard issued in 2014 to January 1, 2018. The standard provides 
guidance on revenue recognition that depicts the transfer of promised 
goods or services to customers in an amount that reflects the 
consideration to which the entity expects to be entitled in exchange 
for those goods and services. The Company is currently assessing the 
impact of adoption of this update on its consolidated financial 
statements. 

In September 2015, the FASB issued an accounting standards 
update that requires an acquirer to recognize adjustments to 
provisional amounts that are identified during the measurement period 
of a business combination in the reporting period in which the

adjustment amounts are determined. This update is applicable to 
Hydro One for the years and interim periods beginning on January 1, 
2016 for measurement adjustments related to business combinations. 

In November 2015, the FASB issued an accounting standards 
update that requires all deferred tax assets and liabilities to be 
classified as noncurrent on the balance sheet. This update is 
applicable to Hydro One for the years and interim periods beginning 
on January 1, 2017. Upon adoption of this update in the first quarter 
of 2017, the current portions of the Company’s deferred income tax 
assets and liabilities will be reclassified as long-term assets and 
liabilities on the consolidated Balance Sheets. 

In January 2016, the FASB issued an accounting standards update 
that requires equity investments to be measured at fair value with 
changes in fair value recognized in net income, and requires 
enhanced disclosures and presentation of financial assets and 
liabilities in the financial statements. This update also simplifies the 
impairment assessment of equity investments without readily 
determinable fair values by requiring a qualitative assessment to 
identify impairment. This update is applicable to Hydro One for the 
years and interim periods beginning on January 1, 2018. The 
Company is currently assessing the impact of adoption of this update 
on its consolidated financial statements. 

Other Matters 

Appointment of New Board of Directors 

In 2015, the Province appointed a fully independent Board of 
Directors to govern Hydro One as a publicly traded company, with a

Net Income and EPS 
The changes to net income and EPS were primarily due to the 
following: 

•  Milder weather resulted in a decrease in transmission revenues, 
mainly due to lower average monthly Ontario 60-minute peak 
demand, and lower net distribution revenues; and 

•  Although expenses related to stabilization of the Company’s 

customer information system were significantly lower than last year, 
OM&A costs increased from last year, primarily due to: 

O  expenses related to write-offs of project and inventory costs 

due to revisions of asset replacement strategies; 

O	  higher storm restoration efforts due to multiple windstorms in 

the fourth quarter of 2015; 

O	 

O	 

timing of preventative maintenance on grid infrastructure; 

insurance proceeds receipts in 2014 that did not re-occur in 
2015; and 

O	  expenditures related to integration of acquired local 

distribution companies. 

Income tax expense for the quarter was reduced by an income tax 
recovery of $19 million due to tax benefits related to the IPO.

Excluding this effect, the fourth quarter 2015 effective tax rate would 
have been approximately 13.8% compared to the fourth quarter 
2014 effective tax rate of approximately 6.6%. 

to place new assets in-service, consistent with its multi-year capital 
investment program. 

Revenues 

The quarterly decrease of $21 million or 5.5% in transmission 
revenues was primarily due to lower average monthly Ontario 
60-minute peak demand associated with unseasonably warm 
weather during the fourth quarter of 2015. 

The quarterly decrease of $120 million or 9.5% in distribution 
revenues was primarily due to lower purchased power costs, the spin-
off of Hydro One Brampton, and lower consumption due primarily to 
milder weather, partially offset by higher OEB-approved distribution 
rates. 

OM&A Costs 

The quarterly increase of $42 million or 48.8% in transmission 
OM&A costs was primarily due to the following: 

•  expenses related to write-offs of project and inventory costs due to 

revisions of asset replacement strategies; 

•  higher volumes of preventative and corrective station maintenance 

on power equipment; 

•  insurance proceeds received in the fourth quarter of 2014 related 

to 2013 floods at the Company’s Richview and Manby 
transformer stations which were recorded as a reduction in 2014 
OM&A costs; 

•  higher expenditures during 2015 related to work required to 

adhere to the NERC Cyber Security standards; and 

•  increased expenditures related to forestry control and line clearing 

on the Company’s transmission rights-of-way. 

The decrease of $2 million or 1.4% in distribution OM&A costs 
during the fourth quarter of 2015 was primarily due to the following: 

•	  a decrease in bad debt expense and lower expenditures related 

to remediation of the Company’s customer information system; and 

•  decreased vegetation management expenditures relating to 

distribution line clearing and forestry control; partially offset by 

•  increased costs associated with responding to power quality-
related issues and outages as a result of multiple wind storms 
which occurred during the fourth quarter of 2015. 

Depreciation and Amortization 

The increase of $3 million or 1.6% in depreciation and amortization 
costs during the fourth quarter of 2015 compared to last year was 
mainly due to the growth in capital assets as the Company continues 

Income Taxes 

The decrease of $14 million in income tax expense for the fourth 
quarter of 2015 compared to 2014 was due to lower income 
before taxes, in addition to the positive effect of an income tax 
recovery associated with the step-up of the tax basis of the assets of 
Hydro One Inc. and its subsidiaries to fair market value in excess of 
the Departure Tax incurred when Hydro One exited the PILs Regime. 

For the fourth quarter of 2015, the Company realized an effective tax 
rate of approximately 0.7%, compared to approximately 6.6% 
realized for the fourth quarter of 2014. The difference in the effective 
tax rates is due primarily to the income tax recovery on the 
revaluation of the assets of Hydro One on exiting the PILs Regime, 
partially offset by a decrease in accelerated capital cost allowance 
over depreciation recognized in 2014 for certain classes of assets. 

Capital Investments 

During the fourth quarter of 2015, the Company made capital 
investments totalling $451 million and placed $607 million of new 
assets in-service. Capital investments in the transmission system during 
the fourth quarter included equipment replacements at the Bruce, 
Richview and Pickering Transmission Stations, and continued work on 
the Company’s major inter-area network and local area supply 
projects, including the Clarington Transmission Station and Guelph 
Area Transmission Refurbishment projects. 

Capital investments in the distribution system during the fourth quarter 
included capital work related to station refurbishment programs and 
wood utility pole replacements, continued investments in new 
customer connections and upgrades, and increased storm restoration 
work as a result of two significant wind storms during the fourth 
quarter of 2015.

and no significant event occurring outside the ordinary course of 
business. These assumptions are based on information currently 
available to the Company, including information obtained from third 
party sources. Actual results may differ materially from those predicted 
by such forward-looking statements. While Hydro One does not 
know what impact any of these differences may have, the 
Company’s business, results of operations, financial condition and 
credit stability may be materially adversely affected. Factors that 
could cause actual results or outcomes to differ materially from the 
results expressed or implied by forward-looking statements include, 
among other things: 

•  risks associated with the Province’s significant share ownership of 
Hydro One and other relationships with the Province, including 
potential conflicts of interest that may arise between Hydro One, 
the Province and related parties; 

•  regulatory risks and risks relating to Hydro One’s revenues, 

including risks relating to rate orders, actual performance against 
forecasts and capital expenditures; 

•  the risk that previously granted regulatory approvals may be 

subsequently challenged, appealed or overturned; 

•  the risk that the Company may be unable to comply with 

regulatory and legislative requirements or that the Company may 
incur additional costs for compliance that are not recoverable 
through rates; 

•  the risk of exposure of the Company’s facilities to the effects of 

severe weather conditions, natural disasters or other unexpected 
occurrences for which the Company is uninsured or for which the 
Company could be subject to claims for damage; 

•  public opposition to and delays or denials of the requisite 

approvals and accommodations for the Company’s planned 
projects; 

•  the risk that Hydro One may incur significant costs associated with 
transferring assets located on Reserves (as defined in the Indian 
Act (Canada)); 

•  the risks associated with information system security and with 

maintaining a complex information technology system 
infrastructure; 

•  the risks related to the Company’s workforce demographic and its 

potential inability to attract and retain qualified personnel; 

•  the risk of labour disputes and inability to negotiate appropriate 
collective agreements on acceptable terms consistent with the 
Company’s rate decisions; 

•  risk that the Company is not able to arrange sufficient cost-effective

Management’s Report
 

The Consolidated Financial Statements, Management’s Discussion 
and Analysis (MD&A) and related financial information have been 
prepared by the management of Hydro One Limited (Hydro One or 
the Company). Management is responsible for the integrity, 
consistency and reliability of all such information presented. The 
Consolidated Financial Statements have been prepared in 
accordance with United States Generally Accepted Accounting 
Principles and applicable securities legislation. The MD&A has been 
prepared in accordance with National Instrument 51-102. 

The preparation of the Consolidated Financial Statements and 
information in the MD&A involves the use of estimates and 
assumptions based on management’s judgment, particularly when 
transactions affecting the current accounting period cannot be 
finalized with certainty until future periods. Estimates and assumptions 
are based on historical experience, current conditions and various 
other assumptions believed to be reasonable in the circumstances, 
with critical analysis of the significant accounting policies followed by 
the Company as described in Note 2 to the Consolidated Financial 
Statements. The preparation of the Consolidated Financial Statements 
and the MD&A includes information regarding the estimated impact 
of future events and transactions. The MD&A also includes information 
regarding sources of liquidity and capital resources, operating trends, 
risks and uncertainties. Actual results in the future may differ materially 
from the present assessment of this information because future events 
and circumstances may not occur as expected. The Consolidated 
Financial Statements and MD&A have been properly prepared within 
reasonable limits of materiality and in light of information up to 
February 11, 2016. 

Management is responsible for establishing and maintaining 
adequate internal control over financial reporting for the Company. In 
meeting its responsibility for the reliability of financial information, 
management maintains and relies on a comprehensive system of 
internal control and internal audit. The system of internal control 
includes a written corporate conduct policy; implementation of a risk 
management framework; effective segregation of duties and 
delegation of authorities; and sound and conservative accounting 
policies that are regularly reviewed. This structure is designed to 
provide reasonable assurance that assets are safeguarded and that 
reliable information is available on a timely basis. In addition, 
management has assessed the design and operating effectiveness of 

the Company’s internal control over financial reporting in accordance 
with the criteria set forth in Internal Control – Integrated Framework 
(2013), issued by the Committee of Sponsoring Organizations of the 
Treadway Commission. Based on this assessment, management 
concluded that the Company maintained effective internal control 
over financial reporting as of December 31, 2015. The effectiveness 
of these internal controls is reported to the Audit Committee of the 
Hydro One Board of Directors, as required. 

The Consolidated Financial Statements have been audited by 
KPMG LLP, independent external auditors appointed by the 
shareholders of the Company. The external auditors’ responsibility is 
to express their opinion on whether the Consolidated Financial 
Statements are fairly presented in accordance with United States 
Generally Accepted Accounting Principles. The Independent Auditors’ 
Report outlines the scope of their examination and their opinion. 

The Hydro One Board of Directors, through its Audit Committee, is 
responsible for ensuring that management fulfills its responsibilities for 
financial reporting and internal controls. The Audit Committee of 
Hydro One met periodically with management, the internal auditors 
and the external auditors to satisfy itself that each group had properly 
discharged its respective responsibility and to review the 
Consolidated Financial Statements before recommending approval 
by the Board of Directors. The external auditors had direct and full 
access to the Audit Committee, with and without the presence of 
management, to discuss their audit findings. 

The President and Chief Executive Officer and the Chief Financial 
Officer have certified Hydro One’s annual Consolidated Financial 
Statements and annual MD&A, related disclosure controls and 
procedures and the design and effectiveness of related internal 
controls over financial reporting. 

On behalf of Hydro One’s management:

Independent Auditors’ Report
 

To the Shareholders of Hydro One Limited 

We have audited the accompanying Consolidated Financial 
Statements of Hydro One Limited, which comprise the 
consolidated balance sheets as at December 31, 2015 and 
December 31, 2014, the consolidated statements of operations and 
comprehensive income, changes in equity and cash flows for the 
years then ended, and notes, comprising a summary of significant 
accounting policies and other explanatory information. 

Management’s Responsibility for the Consolidated 
Financial Statements 

Management is responsible for the preparation and fair presentation 
of these Consolidated Financial Statements in accordance with 
United States Generally Accepted Accounting Principles, 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. 

Auditors’ Responsibility 

Our responsibility is to express an opinion on these Consolidated 
Financial Statements based on our audits. We conducted our audits 
in accordance with Canadian generally accepted auditing 
standards. Those standards require that we comply with ethical 
requirements and plan and perform the audit to obtain reasonable 
assurance about whether the Consolidated Financial Statements are 
free from material misstatement. 

An audit involves performing procedures to obtain audit evidence 
about the amounts and disclosures in the Consolidated Financial 
Statements. The procedures selected depend on our judgment, 

including the assessment of the risks of material misstatement of the 
Consolidated Financial Statements, whether due to fraud or error. In 
making those risk assessments, we consider internal control relevant to 
the entity’s preparation and fair presentation of the Consolidated 
Financial Statements 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 entity’s internal 
control. An audit also includes evaluating the appropriateness of 
accounting policies used and the reasonableness of accounting 
estimates made by management, as well as evaluating the overall 
presentation of the Consolidated Financial Statements. 

We believe that the audit evidence we have obtained in our audits is 
sufficient and appropriate to provide a basis for our audit opinion. 

Opinion 

In our opinion, the Consolidated Financial Statements present fairly, 
in all material respects, the consolidated financial position of Hydro 
One Limited as at December 31, 2015 and December 31, 2014, 
and its consolidated results of operations and its consolidated cash 
flows for the years then ended in accordance with United States 
Generally Accepted Accounting Principles.

Notes to Consolidated Financial Statements
 

For the years ended December 31, 2015 and 2014 

1.  Description of The Business 

Hydro One Limited (Hydro One or the Company) was incorporated 
on August 31, 2015, under the Business Corporations Act (Ontario). 

On October 31, 2015, the Company acquired Hydro One Inc., a 
company previously wholly-owned by the Province of Ontario 
(Province). The acquisition of Hydro One Inc. by Hydro One was 
accounted for as a common control transaction and Hydro One is a 
continuation of business operations of Hydro One Inc. The principal 
businesses of Hydro One are the transmission and distribution of 
electricity to customers within Ontario. 

In November 2015, Hydro One and the Province completed an 
initial public offering (IPO) on the Toronto Stock Exchange of 15% of 
its 595 million outstanding common shares. The proceeds of the 
offering were received by the Province. All of the regulated business 
and outstanding publicly issued notes and debentures of Hydro One 
remain at the Company’s wholly owned subsidiary Hydro One Inc. 
At December 31, 2015, the Province owns 84% of Hydro One. 
See Note 18 for further details regarding the reorganization of 
Hydro One. 

2.  Significant Accounting Policies 
Basis of Consolidation and Preparation 

These Consolidated Financial Statements have been presented in a 
manner similar to the pooling-of-interests method. The financial 
statements consist of the results of operations of Hydro One Inc. prior 
to October 31, 2015, and the consolidated results of operations of 
Hydro One from the date of incorporation on August 31, 2015 to 
December 31, 2015, which include the results of Hydro One Inc. 
subsequent to its acquisition on October 31, 2015. All periods have 
been combined using historical amounts. The comparative 
information consists of the results of Hydro One Inc. as at and for the 
year ended December 31, 2014. In addition, Hydro One’s issued 
and outstanding common shares prior to October 31, 2015 have 
been retroactively adjusted for the purposes of presentation to reflect 
the effects of the acquisition of Hydro One Inc. using the exchange 
ratio established for the acquisition. The accompanying combined 
consolidated and consolidated financial statements are referred to as 
“consolidated” for all periods presented. Intercompany transactions 
and balances have been eliminated. 

On August 31, 2015, Hydro One Inc. completed the spin-off of its 
subsidiary, Hydro One Brampton Networks Inc. (Hydro One 
Brampton) to the Province. See note 4 – Business Combinations. 
These Consolidated Financial Statements include the results of 
operations of Hydro One Brampton up to August 31, 2015. 

Basis of Accounting 

These Consolidated Financial Statements are prepared and presented 
in accordance with United States (US) Generally Accepted 
Accounting Principles (GAAP) and in Canadian dollars. 

Hydro One performed an evaluation of subsequent events through to 
February 11, 2016, the date these Consolidated Financial 
Statements were issued, to determine whether any events or 
transactions warranted recognition and disclosure in these 
Consolidated Financial Statements. See Note 28 – Subsequent 
Events. 

Use of Management Estimates 

The preparation of financial statements requires management to make 
estimates and assumptions that affect the reported amounts of assets 
and liabilities at the date of the financial statements and the reported 
amounts of revenues, expenses, gains and losses during the reporting 
periods. Management evaluates these estimates on an ongoing basis 
based upon historical experience, current conditions, and 
assumptions believed to be reasonable at the time the assumptions 
are made, with any adjustments being recognized in results of 
operations in the period they arise. Significant estimates relate to 
regulatory assets and regulatory liabilities, environmental liabilities, 
pension benefits, post-retirement and post-employment benefits, asset 
retirement obligations, goodwill and asset impairments, 
contingencies, unbilled revenues, allowance for doubtful accounts, 
derivative instruments, and deferred income tax assets and liabilities. 
Actual results may differ significantly from these estimates. 

Rate Setting 

The Company’s Transmission Business consists of the transmission 
business of Hydro One Inc., which includes the transmission business 
of its subsidiary, Hydro One Networks Inc. (Hydro One Networks), 
as well as its 66% interest in B2M Limited Partnership (B2M LP). The

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS 

Company’s Distribution Business consists of the distribution business of 
Hydro One Inc., which includes the distribution businesses of Hydro 
One Networks, Haldimand County Utilities Inc. (Haldimand Hydro), 
Hydro One Remote Communities Inc. (Hydro One Remote 
Communities), and Woodstock Hydro Holdings Inc. (Woodstock 
Hydro). 

The Ontario Energy Board (OEB) has approved the use of US GAAP 
for rate setting and regulatory accounting and reporting by Hydro 
One Networks’ transmission and distribution businesses, as well as 
by Hydro One Remote Communities. 

Transmission 

On January 8, 2015, pursuant to an application filed with the 
OEB, the OEB approved the 2015 Hydro One transmission rates 
revenue requirement, excluding the B2M LP revenue requirement, of 
$1,477 million. 

On June 30, 2015, B2M LP updated its application (originally filed 
March 30, 2015) with the OEB for 2015-2019 transmission rates, 
requesting approval of revenue requirement of $39 million, 
$36 million, $37 million, $38 million and $37 million for the 
respective years. On December 29, 2015, the OEB issued a 
Decision and Order approving the 2015-2019 rates revenue 
requirement, and on January 14, 2016, the OEB approved the 
B2M LP revenue requirement recovery through the 2016 Uniform 
Transmission Rates, and the establishment of a deferral account to 
capture costs of Tax Rate and Rule changes. 

Distribution 

On March 12, 2015, the OEB issued a Decision and Rate Order 
approving a revenue requirement of $1,326 million for 2015, 
$1,430 million for 2016 and $1,486 million for 2017. The revenue 
requirements for 2016 and 2017 are estimates that may change 
based on 2016 and 2017 Rate Orders. On April 23, 2015, the 
Final Rate Order for 2015 rates was approved by the OEB. 

On September 24, 2014, Hydro One Remote Communities filed an 
Incentive Regulation Mechanism application with the OEB for 2015 
rates, seeking approval for increased base rates for the distribution 
and generation of electricity of 1.7%. On March 19, 2015, the OEB 
approved an increase of approximately 1.6% to basic rates for the 
distribution and generation of electricity, with an effective date of 
May 1, 2015. 

Regulatory Accounting 

The OEB has the general power to include or exclude revenues, 
costs, gains or losses in the rates of a specific period, resulting in a 

56  ANNUAL REPORT 2015  HYDRO ONE LIMITED 

TSX: H 

change in the timing of accounting recognition from that which would 
have been applied in an unregulated company. Such change in 
timing involves the application of rate-regulated accounting, giving 
rise to the recognition of regulatory assets and liabilities. The 
Company’s regulatory assets represent certain amounts receivable 
from future customers and costs that have been deferred for 
accounting purposes because it is probable that they will be 
recovered in future rates. In addition, the Company has recorded 
regulatory liabilities that generally represent amounts that are 
refundable to future customers. The Company continually assesses the 
likelihood of recovery of each of its regulatory assets and continues to 
believe that it is probable that the OEB will factor its regulatory assets 
and liabilities into the setting of future rates. If, at some future date, 
the Company judges that it is no longer probable that the OEB will 
include a regulatory asset or liability in setting future rates, the 
appropriate carrying amount will be reflected in results of operations 
in the period that the assessment is made. 

Cash and Cash Equivalents 

Cash and cash equivalents include cash and short-term investments 
with an original maturity of three months or less. 

Revenue Recognition 

Transmission revenues are collected through OEB-approved rates, 
which are based on an approved revenue requirement that includes 
a rate of return. Such revenue is recognized as electricity is 
transmitted and delivered to customers. 

Distribution revenues attributable to the delivery of electricity are 
based on OEB-approved distribution rates and are recognized on an 
accrual basis and include billed and unbilled revenues. Billed 
revenues are based on electricity delivered as measured from 
customer meters. Unbilled revenues are based on an estimate of 
electricity delivered determined by historical trends of consumption 
and are estimated at the end of each month. The unbilled revenue 
estimate is affected by energy consumption, weather, and changes in 
the composition of customer classes. 

Distribution revenue also includes an amount relating to rate 
protection for rural, residential and remote customers, which is 
received from the Independent Electricity System Operator (IESO) 
based on a standardized customer rate that is approved by the OEB. 

Revenues also include amounts related to sales of other services and 
equipment. Such revenue is recognized as services are rendered or 
as equipment is delivered. 

Revenues are recorded net of indirect taxes. 

Accounts Receivable and Allowance for 
Doubtful Accounts 

Billed accounts receivable are recorded at the invoiced amount, net 
of allowance for doubtful accounts. Unbilled accounts receivable are 
recorded at their estimated value. Overdue amounts related to 
regulated billings bear interest at OEB-approved rates. The allowance 
for doubtful accounts reflects the Company’s best estimate of losses 
on billed accounts receivable balances. The Company estimates the 
allowance for doubtful accounts on customer receivables by applying 
internally developed loss rates to the outstanding receivable balances 
by aging category. Loss rates applied to the accounts receivable 
balances are based on historical overdue balances, customer 
payments and write-offs. Accounts receivable are written-off against 
the allowance when they are deemed uncollectible. The existing 
allowance for doubtful accounts will continue to be affected by 
changes in volume, prices and economic conditions. 

Noncontrolling interest 

Noncontrolling interest represents the portion of equity ownership in 
subsidiaries that is not attributable to shareholders of Hydro One. 
Noncontrolling interest is initially recorded at fair value and 
subsequently the amount is adjusted for the proportionate share of net 
income (loss) and other comprehensive income (loss) attributable to 
the noncontrolling interest and any dividends or distributions paid to 
the noncontrolling interest. 

If a transaction results in the acquisition of all, or part, of a 
noncontrolling interest in a subsidiary, the acquisition of the 
noncontrolling interest is accounted for as an equity transaction. No 
gain or loss is recognized in consolidated net income or 
comprehensive income as a result of changes in the noncontrolling 
interest, unless a change results in the loss of control by the 
Company. 

Income Taxes 

By virtue of being wholly owned by the Province, Hydro One was 
exempt from tax under the Income Tax Act (Canada) and the 
Taxation Act, 2007 (Ontario) (Federal Tax Regime). However, under 
the Electricity Act, Hydro One was required to make payments in lieu 
of tax (PILs) to the Ontario Electricity Financial Corporation (OEFC) 
(PILs Regime). The PILs were, in general, based on the amount of tax 
that Hydro One would otherwise be liable to pay under the Federal 
Tax Regime if it was not exempt from taxes under those statutes. 

In connection with the IPO of Hydro One, Hydro One’s exemption 
from tax under the Federal Tax Regime ceased to apply. Upon 
exiting the PILs Regime, Hydro One is required to make corporate 
income tax payments to the Canada Revenue Agency (CRA) under 
the Federal Tax Regime. 

Current and deferred income taxes are computed based on the tax 
rates and tax laws enacted as at the balance sheet date. Tax benefits 
associated with income tax positions taken, or expected to be taken, 
in a tax return are recorded only when the “more-likely-than-not” 
recognition threshold is satisfied and are measured at the largest 
amount of benefit that has a greater than 50% likelihood of being 
realized upon settlement. Management evaluates each position 
based solely on the technical merits and facts and circumstances of 
the position, assuming the position will be examined by a taxing 
authority having full knowledge of all relevant information. Significant 
management judgment is required to determine recognition thresholds 
and the related amount of tax benefits to be recognized in the 
Consolidated Financial Statements. Management re-evaluates tax 
positions each period in which new information about recognition or 
measurement becomes available. 

Deferred Income Taxes 

Deferred income taxes are provided for using the liability method. 
Deferred income taxes are recognized based on the estimated future 
tax consequences attributable to temporary differences between the 
carrying amount of assets and liabilities in the Consolidated Financial 
Statements and their corresponding tax bases. 

Deferred income tax liabilities are generally recognized on all 
taxable temporary differences. Deferred tax assets are recognized to 
the extent that it is more-likely-than-not that these assets will be 
realized from taxable income available against which deductible 
temporary differences can be utilized. 

Deferred income taxes are calculated at the tax rates that are 
expected to apply in the period when the liability is settled or the 
asset is realized, based on the tax rates and tax laws that have been 
enacted as at the balance sheet date. Deferred income taxes that are 
not included in the rate-setting process are charged or credited to the 
Consolidated Statements of Operations and Comprehensive Income. 

If management determines that it is more-likely-than-not that some or 
all of a deferred income tax asset will not be realized, a valuation 
allowance is recorded against the deferred income tax asset to report 
the net balance at the amount expected to be realized. Previously 
unrecognized deferred income tax assets are reassessed at each 
balance sheet date and are recognized to the extent that it has 
become more-likely-than-not that the tax benefit will be realized. 

The Company records regulatory assets and liabilities associated with 
deferred income taxes that will be included in the rate-setting process. 

The Company uses the flow-through method to account for investment 
tax credits (ITCs) earned on eligible scientific research and 
experimental development expenditures, and apprenticeship job

creation. Under this method, only non-refundable ITCs are recognized 
as a reduction to income tax expense. 

Materials and Supplies 

Materials and supplies represent consumables, small spare parts and 
construction materials held for internal construction and maintenance 
of property, plant and equipment. These assets are carried at 
average cost less any impairments recorded. 

Property, Plant and Equipment 

Property, plant and equipment is recorded at original cost, net of 
customer contributions, and any accumulated impairment losses. The 
cost of additions, including betterments and replacement asset 
components, is included on the Consolidated Balance Sheets as 
property, plant and equipment. 

The original cost of property, plant and equipment includes direct 
materials, direct labour (including employee benefits), contracted 
services, attributable capitalized financing costs, asset retirement 
costs, and direct and indirect overheads that are related to the capital 
project or program. Indirect overheads include a portion of corporate 
costs such as finance, treasury, human resources, information 
technology and executive costs. Overhead costs, including corporate 
functions and field services costs, are capitalized on a fully allocated 
basis, consistent with an OEB-approved methodology. 

Property, plant and equipment in service consists of transmission, 
distribution, communication, administration and service assets and 
land easements. Property, plant and equipment also includes future 
use assets, such as land, major components and spare parts, and 
capitalized project development costs associated with deferred 
capital projects. 

Transmission 

Transmission assets include assets used for the transmission of high-
voltage electricity, such as transmission lines, support structures, 
foundations, insulators, connecting hardware and grounding systems, 
and assets used to step up the voltage of electricity from generating 
stations for transmission and to step down voltages for distribution, 
including transformers, circuit breakers and switches. 

Distribution 

Distribution assets include assets related to the distribution of low-
voltage electricity, including lines, poles, switches, transformers, 
protective devices and metering systems. 

58  ANNUAL REPORT 2015  HYDRO ONE LIMITED 

TSX: H 

Communication 

Communication assets include fibre optic and microwave radio 
systems, optical ground wire, towers, telephone equipment and 
associated buildings. 

Administration and Service 

Administration and service assets include administrative buildings, 
personal computers, transport and work equipment, tools and other 
minor assets. 

Easements 

Easements include statutory rights of use for transmission corridors and 
abutting lands granted under the Reliable Energy and Consumer 
Protection Act, 2002, as well as other land access rights. 

Intangible Assets 

Intangible assets separately acquired or internally developed are 
measured on initial recognition at cost, which comprises purchased 
software, direct labour (including employee benefits), consulting, 
engineering, overheads and attributable capitalized financing 
charges. Following initial recognition, intangible assets are carried at 
cost, net of any accumulated amortization and accumulated 
impairment losses. The Company’s intangible assets primarily 
represent major computer applications. 

Capitalized Financing Costs 

Capitalized financing costs represent interest costs attributable to the 
construction of property, plant and equipment or development of 
intangible assets. The financing cost of attributable borrowed funds is 
capitalized as part of the acquisition cost of such assets. The 
capitalized financing costs are a reduction of financing charges 
recognized in the Consolidated Statements of Operations and 
Comprehensive Income. Capitalized financing costs are calculated 
using the Company’s weighted average effective cost of debt. 

Construction and Development in Progress 

Construction and development in progress consists of the capitalized 
cost of constructed assets that are not yet complete and which have 
not yet been placed in service. 

Depreciation and Amortization 

The cost of property, plant and equipment and intangible assets is 
depreciated or amortized on a straight-line basis based on the 
estimated remaining service life of each asset category, except for 
transport and work equipment, which is depreciated on a declining 
balance basis. 

The Company periodically initiates an external independent review of 
its property, plant and equipment and intangible asset depreciation 
and amortization rates, as required by the OEB. Any changes arising 
from OEB approval of such a review are implemented on a 

remaining service life basis, consistent with their inclusion in electricity 
rates. The last review resulted in changes to rates effective January 1, 
2015. A summary of average service lives and depreciation and 
amortization rates for the various classes of assets is included below:

of goodwill. If the implied fair value of goodwill is less than the 
carrying amount, an impairment loss is recorded as a reduction to 
goodwill and as a charge to results of operations. 

In accordance with group depreciation practices, the original cost of 
property, plant and equipment, or major components thereof, and 
intangible assets that are normally retired, is charged to accumulated 
depreciation, with no gain or loss being reflected in results of 
operations. Where a disposition of property, plant and equipment 
occurs through sale, a gain or loss is calculated based on proceeds 
and such gain or loss is included in depreciation expense. 
Depreciation expense also includes the costs incurred to remove 
property, plant and equipment where no asset retirement obligations 
have been recorded. 

Goodwill 

Goodwill represents the cost of acquired local distribution companies 
that is in excess of the fair value of the net identifiable assets acquired 
at the acquisition date. Goodwill is not included in rate base. 

Goodwill is evaluated for impairment on an annual basis, or more 
frequently if circumstances require. The Company performs a 
qualitative assessment to determine whether it is more-likely-than-not 
that the fair value of the applicable reporting unit is less than its 
carrying amount. If the Company determines, as a result of its 
qualitative assessment, that it is not more-likely-than-not that the fair 
value of the applicable reporting unit is less than its carrying amount, 
no further testing is required. If the Company determines, as a result 
of its qualitative assessment, that it is more-likely-than-not that the fair 
value of the applicable reporting unit is less than its carrying amount, 
a goodwill impairment assessment is performed using a two-step, fair 
value-based test. The first step compares the fair value of the 
applicable reporting unit to its carrying amount, including goodwill. If 
the carrying amount of the applicable reporting unit exceeds its fair 
value, a second step is performed. The second step requires an 
allocation of fair value to the individual assets and liabilities using 
purchase price allocation in order to determine the implied fair value 

For the year ended December 31, 2015, based on the qualitative 
assessment performed as at September 30, 2015, the Company has 
determined that it is not more-likely-than-not that the fair value of each 
applicable reporting unit assessed is less than its carrying amount. As 
a result, no further testing was performed, and the Company has 
concluded that goodwill was not impaired at December 31, 2015. 

Long-Lived Asset Impairment 

When circumstances indicate the carrying value of long-lived assets 
may not be recoverable, the Company evaluates whether the 
carrying value of such assets, excluding goodwill, has been 
impaired. For such long-lived assets, the Company evaluates whether 
impairment may exist by estimating future estimated undiscounted 
cash flows expected to result from the use and eventual disposition of 
the asset. When alternative courses of action to recover the carrying 
amount of a long-lived asset are under consideration, a probability-
weighted approach is used to develop estimates of future 
undiscounted cash flows. If the carrying value of the long-lived asset 
is not recoverable based on the estimated future undiscounted cash 
flows, an impairment loss is recorded, measured as the excess of the 
carrying value of the asset over its fair value. As a result, the asset’s 
carrying value is adjusted to its estimated fair value. 

Within its regulated business, the carrying costs of most of Hydro 
One’s long-lived assets are included in rate base where they earn an 
OEB-approved rate of return. Asset carrying values and the related 
return are recovered through approved rates. As a result, such assets 
are only tested for impairment in the event that the OEB disallows 
recovery, in whole or in part, or if such a disallowance is judged to 
be probable. 

Hydro One regularly monitors the assets of its unregulated Hydro 
One Telecom subsidiary for indications of impairment. Management

assesses the fair value of such long-lived assets using commonly 
accepted techniques, and may use more than one. Techniques used 
to determine fair value include, but are not limited to, the use of 
recent third party comparable sales for reference and internally 
developed discounted cash flow analysis. Significant changes in 
market conditions, changes to the condition of an asset, or a change 
in management’s intent to utilize the asset are generally viewed by 
management as triggering events to reassess the cash flows related to 
these long-lived assets. As at December 31, 2015 and 2014, no 
asset impairment had been recorded for assets within either the 
Company’s regulated or unregulated businesses. 

Costs of Arranging Debt Financing 

For financial liabilities classified as other than held-for-trading, the 
Company defers the external transaction costs related to obtaining 
debt financing and presents such amounts as deferred debt issuance 
costs on the Consolidated Balance Sheets. Deferred debt issuance 
costs are amortized over the contractual life of the related debt on an 
effective-interest basis and the amortization is included within 
financing charges in the Consolidated Statements of Operations and 
Comprehensive Income. Transaction costs for items classified as held­
for-trading are expensed immediately. 

Comprehensive Income 

Comprehensive income is comprised of net income and other 
comprehensive income (OCI). Hydro One presents net income and 
OCI in a single continuous Consolidated Statement of Operations 
and Comprehensive Income. 

Financial Assets and Liabilities 

All financial assets and liabilities are classified into one of the 
following five categories: held-to-maturity; loans and receivables; 
held-for-trading; other liabilities; or available-for-sale. Financial assets 
and liabilities classified as held-for-trading are measured at fair value. 
All other financial assets and liabilities are measured at amortized 
cost, except accounts receivable and amounts due from related 
parties, which are measured at the lower of cost or fair value. 
Accounts receivable and amounts due from related parties are 
classified as loans and receivables. The Company considers the 
carrying amounts of accounts receivable and amounts due from 
related parties to be reasonable estimates of fair value because of the 
short time to maturity of these instruments. Provisions for impaired 
accounts receivable are recognized as adjustments to the allowance 
for doubtful accounts and are recognized when there is objective 
evidence that the Company will not be able to collect amounts 
according to the original terms. All financial instrument transactions 
are recorded at trade date. 

60  ANNUAL REPORT 2015  HYDRO ONE LIMITED 

TSX: H 

Derivative instruments are measured at fair value. Gains and losses 
from fair valuation are included within financing charges in the period 
in which they arise. The Company determines the classification of its 
financial assets and liabilities at the date of initial recognition. The 
Company designates certain of its financial assets and liabilities to be 
held at fair value, when it is consistent with the Company’s risk 
management policy disclosed in Note 13 – Fair Value of Financial 
Instruments and Risk Management. 

Derivative Instruments and Hedge Accounting 

The Company closely monitors the risks associated with changes in 
interest rates on its operations and, where appropriate, uses various 
instruments to hedge these risks. Certain of these derivative instruments 
qualify for hedge accounting and are designated as accounting 
hedges, while others either do not qualify as hedges or have not 
been designated as hedges (hereinafter referred to as undesignated 
contracts) as they are part of economic hedging relationships. 

The accounting guidance for derivative instruments requires the 
recognition of all derivative instruments not identified as meeting the 
normal purchase and sale exemption as either assets or liabilities 
recorded at fair value on the Consolidated Balance Sheets. For 
derivative instruments that qualify for hedge accounting, the Company 
may elect to designate such derivative instruments as either cash flow 
hedges or fair value hedges. The Company offsets fair value amounts 
recognized on its Consolidated Balance Sheets related to derivative 
instruments executed with the same counterparty under the same 
master netting agreement. 

For derivative instruments that qualify for hedge accounting and which 
are designated as cash flow hedges, the effective portion of any gain 
or loss, net of tax, is reported as a component of accumulated OCI 
(AOCI) and is reclassified to results of operations in the same period 
or periods during which the hedged transaction affects results of 
operations. Any gains or losses on the derivative instrument that 
represent either hedge ineffectiveness or hedge components excluded 
from the assessment of effectiveness are recognized in results of 
operations. For fair value hedges, changes in fair value of both the 
derivative instrument and the underlying hedged exposure are 
recognized in the Consolidated Statements of Operations and 
Comprehensive Income in the current period. The gain or loss on the 
derivative instrument is included in the same line item as the offsetting 
gain or loss on the hedged item in the Consolidated Statements of 
Operations and Comprehensive Income. Additionally, the Company 
enters into derivative agreements that are economic hedges which 
either do not qualify for hedge accounting or have not been 
designated as hedges. The changes in fair value of these 
undesignated derivative instruments are reflected in results of 
operations. 

Embedded derivative instruments are separated from their host 
contracts and carried at fair value on the Consolidated Balance 
Sheets when: (a) the economic characteristics and risks of the 
embedded derivative are not clearly and closely related to the 
economic characteristics and risks of the host contract; (b) the hybrid 
instrument is not measured at fair value, with changes in fair value 
recognized in results of operations each period; and (c) the 
embedded derivative itself meets the definition of a derivative. The 
Company does not engage in derivative trading or speculative 
activities and had no embedded derivatives at December 31, 2015 
or 2014. 

Hydro One periodically develops hedging strategies taking into 
account risk management objectives. At the inception of a hedging 
relationship where the Company has elected to apply hedge 
accounting, Hydro One formally documents the relationship between 
the hedged item and the hedging instrument, the related risk 
management objective, the nature of the specific risk exposure being 
hedged, and the method for assessing the effectiveness of the 
hedging relationship. The Company also assesses, both at the 
inception of the hedge and on a quarterly basis, whether the hedging 
instruments are effective in offsetting changes in fair values or cash 
flows of the hedged items. 

Employee Future Benefits 

Employee future benefits provided by Hydro One include pension, 
post-retirement and post-employment benefits. The costs of the 
Company’s pension, post-retirement and post-employment benefit 
plans are recorded over the periods during which employees render 
service. 

The Company recognizes the funded status of its defined benefit 
pension, post-retirement and post-employment plans on its 
Consolidated Balance Sheets and subsequently recognizes the 
changes in funded status at the end of each reporting year. Defined 
benefit pension, post-retirement and post-employment plans are 
considered to be underfunded when the projected benefit obligation 
exceeds the fair value of the plan assets. Liabilities are recognized on 
the Consolidated Balance Sheets for any net underfunded projected 
benefit obligation. The net underfunded projected benefit obligation 
may be disclosed as a current liability, long-term liability, or both. The 
current portion is the amount by which the actuarial present value of 
benefits included in the benefit obligation payable in the next 12 
months exceeds the fair value of plan assets. If the fair value of plan 
assets exceeds the projected benefit obligation of the plan, an asset 
is recognized equal to the net overfunded projected benefit 
obligation. The post-retirement and post-employment benefit plans are 
unfunded because there are no related plan assets. 

Pension benefits 

Pension costs are recorded on an accrual basis for financial reporting 
purposes. Pension costs are actuarially determined using the 
projected benefit method prorated on service and are based on 
assumptions that reflect management’s best estimate of the effect of 
future events, including future compensation increases. Past service 
costs from plan amendments and all actuarial gains and losses are 
amortized on a straight-line basis over the expected average 
remaining service period of active employees in the plan, and over 
the estimated remaining life expectancy of inactive employees in the 
plan. Pension plan assets, consisting primarily of listed equity 
securities as well as corporate and government debt securities, are 
fair valued at the end of each year. Hydro One records a regulatory 
asset equal to the net underfunded projected benefit obligation for its 
pension plan. 

Post-retirement and post-employment benefits 

Post-retirement and post-employment benefits are recorded and 
included in rates on an accrual basis. Costs are determined by 
independent actuaries using the projected benefit method prorated on 
service and based on assumptions that reflect management’s best 
estimates. Past service costs from plan amendments are amortized to 
results of operations based on the expected average remaining 
service period. Hydro One records a regulatory asset equal to the 
incremental net unfunded projected benefit obligation for post-
retirement and post-employment plans recorded at each year end 
based on annual actuarial reports. 

For post-retirement benefits, all actuarial gains or losses are deferred 
using the “corridor” approach. The amount calculated above the 
“corridor” is amortized to results of operations on a straight-line basis 
over the expected average remaining service life of active employees 
in the plan and over the remaining life expectancy of inactive 
employees in the plan. The post-retirement benefit obligation is 
remeasured to its fair value at each year end based on an annual 
actuarial report, with an offset to the associated regulatory asset, to 
the extent of the remeasurement adjustment. 

For post-employment obligations, the associated regulatory liabilities 
representing actuarial gains on transition to US GAAP are amortized 
to results of operations based on the “corridor” approach. Post 
transition, the actuarial gains and losses on post-employment 
obligations that are incurred during the year are recognized 
immediately to results of operations. The post-employment benefit 
obligation is remeasured to its fair value at each year end based on 
an annual actuarial report, with an offset to the associated regulatory 
asset, to the extent of the remeasurement adjustment.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS 

All post-retirement and post-employment future benefit costs are 
attributed to labour and are either charged to results of operations or 
capitalized as part of the cost of property, plant and equipment and 
intangible assets. 

Multiemployer Pension Plan 

Former employees of Haldimand Hydro and Woodstock Hydro 
participate in the Ontario Municipal Employees Retirement System 
Fund (OMERS Plan), a multiemployer, contributory, defined benefit 
public sector pension fund. Former employees of Norfolk Power Inc. 
(Norfolk Power) ceased to contribute to the OMERS Plan upon 
integration of Norfolk Power into Hydro One Networks in September 
2015. These employees are now included in Hydro One’s defined 
benefit pension plan. OMERS Plan provides retirement pension 
payments based on members’ length of service and salary. Both the 
participating employers and members are required to make plan 
contributions. The OMERS Plan assets are pooled together to provide 
benefits to all plan participants and the plan assets are not 
segregated by member entity. The OMERS Plan is registered with the 
Financial Services Commission of Ontario under Registration 
#0345983. 

The OMERS Plan is accounted for as a defined contribution plan by 
Hydro One because it is not practicable to determine the present 
value of the Company’s obligation, the fair value of plan assets or the 
related current service cost applicable to employees of Haldimand 
Hydro and Woodstock Hydro. Hydro One recognizes its 
contributions to the OMERS Plan as pension expense, with a portion 
being capitalized. The expensed amount is included in operation, 
maintenance and administration costs in the Consolidated Statements 
of Operations and Comprehensive Income. 

Stock-Based Compensation 

Hydro One measures share grant plans based on fair value of share 
grants as estimated based on the grant date share price. The costs 
are recognized in the financial statements using the graded-vesting 
attribution method for share grant plans that have both a performance 
condition and a service condition. The Company records a 
regulatory asset equal to the accrued costs of share grant plans 
recognized in each period, as management considers it to be 
probable that such costs will be recovered in the future through the 
rate-setting process. 

The Company also records the liabilities associated with its Directors’ 
Deferred Share Unit (DSU) Plan at fair value at each reporting date 
until settlement, recognizing compensation expense over the vesting 
period on a straight-line basis. The fair value of the DSU liability is 
based on the Company’s common share closing price at the end of 
each reporting period.

TSX: H 

Loss Contingencies 

Hydro One is involved in certain legal and environmental matters that 
arise in the normal course of business. In the preparation of its 
Consolidated Financial Statements, management makes judgments 
regarding the future outcome of contingent events and records a loss 
for a contingency based on its best estimate when it is determined 
that such loss is probable and the amount of the loss can be 
reasonably estimated. Where the loss amount is recoverable in future 
rates, a regulatory asset is also recorded. When a range estimate for 
the probable loss exists and no amount within the range is a better 
estimate than any other amount, the Company records a loss at the 
minimum amount within the range. 

Management regularly reviews current information available to 
determine whether recorded provisions should be adjusted and 
whether new provisions are required. Estimating probable losses may 
require analysis of multiple forecasts and scenarios that often depend 
on judgments about potential actions by third parties, such as federal, 
provincial and local courts or regulators. Contingent liabilities are 
often resolved over long periods of time. Amounts recorded in the 
Consolidated Financial Statements may differ from the actual outcome 
once the contingency is resolved. Such differences could have a 
material impact on future results of operations, financial position and 
cash flows of the Company. 

Provisions are based upon current estimates and are subject to 
greater uncertainty where the projection period is lengthy. A 
significant upward or downward trend in the number of claims filed, 
the nature of the alleged injuries, and the average cost of resolving 
each claim could change the estimated provision, as could any 
substantial adverse or favourable verdict at trial. A federal or 
provincial legislative outcome or structured settlement could also 
change the estimated liability. Legal fees are expensed as incurred. 

Environmental Liabilities 

Environmental liabilities are recorded in respect of past contamination 
when it is determined that future environmental remediation 
expenditures are probable under existing statute or regulation and the 
amount of the future expenditures can be reasonably estimated. 
Hydro One records a liability for the estimated future expenditures 
associated with contaminated land assessment and remediation and 
for the phase-out and destruction of polychlorinated biphenyl (PCB)­
contaminated mineral oil removed from electrical equipment, based 
on the present value of these estimated future expenditures. The 
Company determines the present value with a discount rate equal to 
its credit-adjusted risk-free interest rate on financial instruments with 
comparable maturities to the pattern of future environmental 
expenditures. As the Company anticipates that the future expenditures 
will continue to be recoverable in future rates, an offsetting regulatory 

asset has been recorded to reflect the future recovery of these 
environmental expenditures from customers. Hydro One reviews its 
estimates of future environmental expenditures annually, or more 
frequently if there are indications that circumstances have changed. 

Asset Retirement Obligations 

Asset retirement obligations are recorded for legal obligations 
associated with the future removal and disposal of long-lived assets. 
Such obligations may result from the acquisition, construction, 
development and/or normal use of the asset. Conditional asset 
retirement obligations are recorded when there is a legal obligation 
to perform a future asset retirement activity but where the timing and/ 
or method of settlement are conditional on a future event that may or 
may not be within the control of the Company. In such a case, the 
obligation to perform the asset retirement activity is unconditional 
even though uncertainty exists about the timing and/or method of 
settlement. 

When recording an asset retirement obligation, the present value of 
the estimated future expenditures required to complete the asset 
retirement activity is recorded in the period in which the obligation is 
incurred, if a reasonable estimate can be made. In general, the 
present value of the estimated future expenditures is added to the 
carrying amount of the associated asset and the resulting asset 
retirement cost is depreciated over the estimated useful life of the 
asset. Where an asset is no longer in service when an asset 
retirement obligation is recorded, the asset retirement cost is recorded 
in results of operations. 

Some of the Company’s transmission and distribution assets, 
particularly those located on unowned easements and rights-of-way, 
may have asset retirement obligations, conditional or otherwise. The 
majority of the Company’s easements and rights-of-way are either of 
perpetual duration or are automatically renewed annually. Land rights 
with finite terms are generally subject to extension or renewal. As the 
Company expects to use the majority of its facilities in perpetuity, no 
asset retirement obligations currently exist for these assets. If, at some 
future date, a particular facility is shown not to meet the perpetuity 
assumption, it will be reviewed to determine whether an estimable 
asset retirement obligation exists. In such a case, an asset retirement 
obligation would be recorded at that time. 

The Company’s asset retirement obligations recorded to date relate to 
estimated future expenditures associated with the removal and 
disposal of asbestos-containing materials installed in some of its 
facilities and with the decommissioning of specific switching stations 
located on unowned sites. 

3.  New Accounting Pronouncements 
Recent Accounting Guidance Not Yet Adopted 

In January 2015, the Financial Accounting Standards Board (FASB) 
issued Accounting Standards Update (ASU) 2015-01, Income 
Statement – Extraordinary and Unusual Items (Subtopic 225-20): 
Simplifying Income Statement Presentation by Eliminating the Concept 
of Extraordinary Items. This ASU eliminates the requirements for 
reporting entities to consider whether an underlying event or 
transaction is extraordinary and to show the item separately in the 
income statement. This ASU is effective for fiscal years, and interim 
periods within these years, beginning after December 15, 2015. The 
adoption of this ASU is not anticipated to have an impact on the 
Company’s consolidated financial statements. 

In February 2015, the FASB issued ASU 2015-02, Consolidation 
(Topic 810): Amendments to the Consolidation Analysis. This ASU 
provides guidance about the analysis that a reporting entity must 
perform to determine whether it should consolidate certain types of 
legal entities. This ASU is effective for fiscal years, and interim 
periods within those years, beginning after December 15, 2015. The 
adoption of this ASU is not anticipated to have an impact on the 
Company’s consolidated financial statements. 

In April 2015, the FASB issued ASU 2015-03, Interest – Imputation 
of Interest (Subtopic 835-30): Simplifying the Presentation of Debt 
Issuance Costs. This ASU requires that debt issuance costs related to 
a recognized debt liability be presented in the balance sheet as a 
direct deduction from the carrying amount of that debt liability. The 
recognition and measurement guidance for debt issuance costs are 
not affected. This ASU is effective for fiscal years, and interim periods 
within those years, beginning after December 15, 2015. Upon 
adoption of this ASU in the first quarter of 2016, the Company’s 
deferred debt issuance costs that are currently presented under other 
long-term assets will be reclassified as a deduction from the carrying 
amount of long-term debt. 

In April 2015, the FASB issued ASU 2015-04, Compensation – 
Retirement Benefits (Topic 715): Practical Expedient for the 
Measurement Date of an Employer’s Defined Benefit Obligation and 
Plan Assets. This ASU permits an entity with a fiscal year-end that 
does not coincide with a month-end and an entity that has a 
significant event in an interim period that calls for a remeasurement of 
defined benefit plan assets and obligations to measure the defined 
benefit plan assets and obligations using the month-end that is closest 
to the entity’s fiscal year-end. This ASU is effective for fiscal years, 
and interim periods within these years, beginning after December 15, 
2015. The adoption of this ASU is not anticipated to have an impact 
on the Company’s consolidated financial statements.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS 

In April 2015, the FASB issued ASU 2015-05, Intangibles – 
Goodwill and Other – Internal-Use Software (Subtopic 350-40): 
Customer’s Accounting for Fees Paid in a Cloud Computing 
Arrangement. This ASU provides guidance to customers about 
whether a cloud computing arrangement includes a software license, 
as well as the related accounting for the arrangement. This ASU is 
effective for fiscal years, and interim periods within these years, 
beginning after December 15, 2015. The Company is currently 
assessing the impact of adoption of this ASU on its consolidated 
financial statements. 

In August 2015, the FASB issued ASU 2015-14, Revenue from 
Contracts with Customers (Topic 606): Deferral of the Effective Date. 
This ASU defers by one year the effective date of ASU 2014-09, 
Revenue from Contracts with Customers (Topic 606) issued by the 
FASB in May 2014. ASU 2014-09 provides guidance on revenue 
recognition that depicts the transfer of promised goods or services to 
customers in an amount that reflects the consideration to which the 
entity expects to be entitled in exchange for those goods and 
services. The guidance in ASU 2014-09 is now effective for fiscal 
years, and interim periods within those years, beginning after 
December 15, 2017. The Company is currently assessing the impact 
of adoption of ASU 2014-09 on its consolidated financial 
statements. 

In September 2015, the FASB issued ASU 2015-16, Business 
Combinations (Topic 805): Simplifying the Accounting for 
Measurement-Period Adjustments. The amendments in this ASU 
require that an acquirer recognize adjustments to provisional amounts 
that are identified during the measurement period of a business 
combination in the reporting period in which the adjustment amounts 
are determined. The amendments in this update require that the 
acquirer to present separately on the face of the income statement or 
disclose in the notes the portion of the amount recorded in current-
period earnings by line item that would have been recorded in 
previous reporting periods if the adjustment to the provisional amounts 

had been recognized as of the acquisition date. This ASU is effective 
for fiscal years, and interim periods within those years, beginning 
after December 15, 2015. Upon adoption of this ASU in the first 
quarter of 2016, the Company will apply the guidance in this ASU 
to future measurement adjustments related to business combinations, 
as applicable. 

In November 2015, the FASB issued ASU 2015-17, Income Taxes 
(Topic 740): Balance Sheet Classification of Deferred Taxes. The 
amendments in this ASU require that all deferred tax assets and 
liabilities be classified as noncurrent on the balance sheet. This ASU 
is effective for fiscal years, and interim periods within those years, 
beginning after December 15, 2016. Upon adoption of this ASU in 
the first quarter of 2017, the current portions of the Company’s 
deferred income tax assets and liabilities will be reclassified as 
noncurrent assets and liabilities on the consolidated Balance Sheets. 

In January 2016, the FASB issued ASU 2016-01, Financial 
Instruments – Overall (Subtopic 825-10): Recognition and 
Measurement of Financial Assets and Financial Liabilities. This ASU 
requires equity investments to be measured at fair value with changes 
in fair value recognized in net income, and requires enhanced 
disclosures and presentation of financial assets and liabilities in the 
financial statements. This ASU also simplifies the impairment 
assessment of equity investments without readily determinable fair 
values by requiring a qualitative assessment to identify impairment. 
This ASU is effective for fiscal years, and interim periods within those 
years, beginning after December 15, 2017. The Company is 
currently assessing the impact of adoption of this ASU on its 
consolidated financial statements.

The preliminary determination of the fair value of assets acquired and 
liabilities assumed has been based upon management’s preliminary 
estimates and certain assumptions with respect to the fair values of the 
assets acquired and liabilities assumed. Due to the timing of the 
transaction, the Company has not yet completed the final fair value 
measurements as at December 31, 2015. In addition, the purchase 
agreement provides for final purchase price adjustments based on 
agreed working capital and other balances at the acquisition date 
which have not yet been finalized. The Company will continue to 
review information and perform further analysis prior to finalizing the 
total purchase price and the fair values of the assets acquired and 
liabilities assumed. The actual total purchase price and the fair values 
of the assets acquired and liabilities assumed may differ from the 
amounts above. 

Goodwill of approximately $17 million arising from the Woodstock 
Hydro acquisition consists largely of the synergies and economies of 
scale expected from combining the operations of Hydro One and 
Woodstock Hydro. All of the goodwill was assigned to Hydro One’s 
Distribution Business segment. Woodstock Hydro contributed 
revenues of $12 million and net income of $2 million to the 
Company’s consolidated financial results for the year ended 
December 31, 2015. All costs related to the acquisition have been 
expensed through the Consolidated Statements of Operations and 
Comprehensive Income. Woodstock Hydro’s financial information is 
not material to the Company’s consolidated financial results for the 
year ended December 31, 2015 and therefore, has not been 
disclosed on a pro forma basis. 

Hydro One Brampton Spin-off 

On August 31, 2015, Hydro One completed the spin-off of its 
subsidiary, Hydro One Brampton. The spin-off was accounted as a 
non-monetary, nonreciprocal transfer with the Province, based on its 
carrying values at August 31, 2015. Transactions that immediately 
preceded the spin-off as well as the spin-off were as follows: 

•  Hydro One subscribed for 357 common shares of Hydro One 
Brampton for an aggregate subscription price of $53 million; 

•  Hydro One transferred to a company wholly owned by the 

Province all the issued and outstanding shares of Hydro One 
Brampton as a dividend-in-kind; and all of the long-term 
intercompany debt in aggregate principal amount of $193 million 
plus accrued interest of $3 million owed by Hydro One Brampton 
to Hydro One as a return of stated capital of $196 million on its 
common shares. 

In connection with the Hydro One Brampton spin-off, the following assets and liabilities of Hydro One Brampton were transferred: 

(millions of Canadian dollars) 

Working capital 
Property, plant and equipment and intangibles (net) 
Other long-term assets 
Long-term liabilities

The provision for PILs / current income taxes is remitted to, or 
received from, the OEFC (PILs Regime) and the CRA (Federal Tax 
Regime). At December 31, 2015, $12 million (2014 – $39 million) 
due from the OEFC was included in due from related parties and 
$1 million (2014 – $nil) due from the CRA was included in prepaid 
expenses and other assets on the Consolidated Balance Sheet. 

In connection with the IPO, Hydro One’s exemption from tax under 
the Federal Tax Regime ceased to apply. Under the PILs Regime, 
Hydro One was deemed to have disposed of its assets immediately 
before it lost its tax exempt status under the Federal Tax Regime, 
resulting in Hydro One making payments in lieu of tax (Departure 
Tax) totalling $2.6 billion. To enable Hydro One to make the 
Departure Tax payment, the Province subscribed for common shares 

of Hydro One for $2.6 billion (See Note 18 – Share Capital). Hydro 
One used the proceeds of this share subscription to pay the 
Departure Tax. 

At December 31, 2015, the total income taxes / provision for PILs 
includes deferred income taxes / recovery of PILs of $2,844 million 
(2014 – deferred provision of $10 million), including $2,810 million 
(2014 – $nil) resulting from transition from the PILs Regime to the 
Federal Tax Regime, that is not included in the rate-setting process, 
using the liability method of accounting. Deferred income taxes / PILs 
balances expected to be included in the rate-setting process are offset 
by regulatory assets and liabilities to reflect the anticipated recovery 
or disposition of these balances within future electricity rates.

In 2015, the Company revised the method to estimate the unbilled 
accounts receivable by using new technology that improved the 
estimation process. This change has been accounted for on a 
prospective basis in the consolidated financial statements at 
December 31, 2015. At December 31, 2015, the change in 

estimation technology resulted in a reduction in unbilled accounts 
receivable of approximately $121 million, with a corresponding 
offset to various components of the retail settlement variance accounts 
(RSVA). The change in estimate had no significant impact on 2015 
net income.

Deferred Income Tax Regulatory Asset and 
Liability 

Deferred income taxes are recognized on temporary differences 
between the carrying amount of assets and liabilities in the financial 
statements and the corresponding tax bases used in the computation 
of taxable income. The Company has recognized regulatory assets 
and liabilities that correspond to deferred income taxes that flow 
through the rate-setting process. In the absence of rate-regulated 
accounting, the Company’s income tax expense would have been 
recognized using the liability method and there would be no 
regulatory accounts established for taxes to be recovered through 
future rates. As a result, the 2015 income tax expense would have 
been higher by approximately $101 million (2014 – $132 million). 

Pension Benefit Regulatory Asset 

In accordance with OEB rate orders, pension costs are recorded on 
a cash basis as employer contributions are paid to the pension fund 
in accordance with the Pension Benefits Act (Ontario). The Company 
recognizes the net unfunded status of pension obligations on the 
Consolidated Balance Sheets with an offset to the associated 
regulatory asset. A regulatory asset is recognized because 
management considers it to be probable that pension benefit costs 
will be recovered in the future through the rate-setting process. The 
pension benefit obligation is remeasured to its fair value at each year 
end based on an annual actuarial report, with an offset to the 
associated regulatory asset, to the extent of the remeasurement 
adjustment. In the absence of rate-regulated accounting, 2015 OCI 
would have been higher by $284 million (2014 – lower by 
$391 million).

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS 

Post-Retirement and Post-Employment Benefits 
The Company recognizes the net unfunded status of post-retirement 
and post-employment obligations on the Consolidated Balance 
Sheets with an incremental offset to the associated regulatory assets. 
A regulatory asset is recognized because management considers it to 
be probable that post-retirement and post-employment benefit costs 
will be recovered in the future through the rate-setting process. The 
post-retirement and post-employment benefit obligation is remeasured 
to its fair value at each year end based on an annual actuarial 
report, with an offset to the associated regulatory asset, to the extent 
of the remeasurement adjustment. In the absence of rate-regulated 
accounting, 2015 OCI would have been higher by $33 million 
(2014 – $35 million). 

Pension Cost Variance 

A pension cost variance account was established for Hydro One 
Networks’ transmission and distribution businesses to track the 
difference between the actual pension expenses incurred and 
estimated pension costs approved by the OEB. The balance in this 
regulatory account reflects the excess of pension costs paid as 
compared to OEB-approved amounts. In March 2015, the OEB 
approved the disposition of the distribution business portion of the 
total pension cost variance account at December 31, 2013, 
including accrued interest, which will be recovered through the 
2015-2017 Rate Rider. In the absence of rate-regulated accounting, 
2015 revenue would have been lower by $6 million (2014 – 
$10 million). 

Environmental 
Hydro One records a liability for the estimated future expenditures 
required to remediate environmental contamination. Because such 
expenditures are expected to be recoverable in future rates, the 
Company has recorded an equivalent amount as a regulatory asset. 
In 2015, the environmental regulatory asset decreased by 
$24 million (2014 – $33 million) to reflect related changes in the 
Company’s PCB liability, and increased by $1 million (2014 – 
$13 million) due to changes in the land assessment and remediation 
liability. The environmental regulatory asset is amortized to results of 
operations based on the pattern of actual expenditures incurred and 
charged to environmental liabilities. The OEB has the discretion to 
examine and assess the prudency and the timing of recovery of all of 
Hydro One’s actual environmental expenditures. In the absence of 
rate-regulated accounting, 2015 operation, maintenance and 
administration expenses would have been lower by $23 million 
(2014 – $20 million). In addition, 2015 amortization expense 
would have been lower by $19 million (2014 – $18 million), and 
2015 financing charges would have been higher by $10 million 
(2014 – $11 million). 

RSVA 
Hydro One has deferred certain retail settlement variance amounts 
under the provisions of Article 490 of the OEB’s Accounting 
Procedures Handbook. In March 2015, the OEB approved the 
disposition of the total RSVA balance accumulated from January 
2012 to December 2013, including accrued interest, to be 
recovered through the 2015-2017 Rate Rider. In 2015, the 
Company revised its method to estimate the unbilled accounts 
receivable based on new technology implemented to improve the 
accuracy of the estimation process. At December 31, 2015, the 
change in estimate reduced unbilled accounts receivable by 
approximately $121 million, with a corresponding offset to various 
components of RSVA. The change in estimate had no significant 
impact on 2015 net income.

2015-2017 Rate Rider 

In March 2015, as part of its decision on Hydro One Networks’ 
Distribution rate application for 2015-2019 the OEB approved the 
disposition of certain deferral and variance accounts, including 
RSVAs and accrued interest. The 2015-2017 Rate Rider account 
includes the balances approved for disposition by the OEB and will 
be disposed over a 32-month period in accordance with the OEB 
decision. 

DSC Exemption 

In June 2010, Hydro One Networks filed an application with the 
OEB regarding the OEB’s new cost responsibility rules contained in 
the OEB’s October 2009 Notice of Amendment to the Distribution 
System Code (DSC), with respect to the connection of certain 
renewable generators that were already connected or that had 
received a connection impact assessment prior to October 21, 
2009. The application sought approval to record and defer the 
unanticipated costs incurred by Hydro One Networks that resulted 
from the connection of certain renewable generation facilities. The 
OEB ruled that identified specific expenditures can be recorded in a 
deferral account subject to the OEB’s review in subsequent Hydro 
One Network distribution applications. In March 2015, the OEB 
approved the disposition of the DSC exemption deferral account at 
December 31, 2013, including accrued interest, which will be 
recovered through the 2015-2017 Rate Rider. In addition, the OEB 
also approved Hydro One’s request to discontinue this deferral 
account, and there were no additions to this regulatory account in 
2015. 

Share-based Compensation 

The Company recognizes costs associated with stock-based 
compensation in a regulatory asset as management considers it 
probable that stock-based compensation costs will be recovered in 
the future through the rate-setting process. At December 31, 2015 the 

CDM Deferral Variance Account 

As part of Hydro One Networks’ application for 2013 and 2014 
transmission rates, Hydro One agreed to establish a new regulatory 
deferral variance account to track the impact of actual Conservation 
and Demand Management (CDM) and demand response results on 
the load forecast compared to the estimated load forecast included in 
the revenue requirement. At December 31, 2014, the balance in the 
CDM deferral variance account relates to the actual 2013 CDM 
compared to the amounts included in 2013 revenue requirement. At 
December 31, 2015, the balance also includes the difference 
between the actual 2014 CDM compared to the amounts included 
in 2014 revenue requirement. The OEB rate order specifically states 
that the IESO (Ontario Power Authority (OPA) prior to January 1, 
2015) data used to calculate the difference between forecasted and 
actual savings will be provided one year in arrears, and as a result, 
no amount should be recorded in advance of notification from the 
IESO of actual results. 

PST Savings Deferral Account 

The provincial sales tax (PST) and goods and services tax (GST) were 
harmonized in July 2010. Unlike the GST, the PST was included in 
operation, maintenance and administration expenses or capital 
expenditures for past revenue requirements approved during a full 
cost-of-service hearing. Under the harmonized sales tax (HST) regime, 
the HST included in operation, maintenance and administration 
expenses or capital expenditures is not a cost ultimately borne by the 
Company and as such, a refund of the prior PST element in the 
approved revenue requirement is applicable, and calculations for 
tracking and refund were requested by the OEB. For Hydro One 
Networks’ transmission revenue requirement, PST was included 
between July 1, 2010 and December 31, 2010 and recorded in a 
deferral account, per direction from the OEB. For Hydro One 
Networks’ distribution revenue requirement, PST was included 
between July 1, 2010 and December 31, 2015 and recorded in a 
deferral account, as directed by the OEB. In March 2015, the OEB 
approved the disposition of the PST Savings Deferral account at 
December 31, 2013, including accrued interest, which will be 
recovered through the 2015-2017 Rate Rider. 

stock-based compensation costs relate to the share grant plans, are 
measured at fair value estimated based on grant date share price 
and recognized using the graded-vesting attribution method. In the 
absence of rate-regulated accounting 2015 operation, maintenance 
and administration expenses would have been higher by $5 million 
(2014 – $nil). 

B2M LP Start-up Costs 

In December 2015, OEB issued its decision on B2M LP’s application 
for 2015-2019 and as part of the decision approved the recovery of 
$8 million of start-up costs relating to B2M LP. The costs will be 
recovered over a 4 year period beginning in 2016, in accordance 
with the OEB decision. 

OEB Cost Assessment Differential 

In April 2010, the OEB issued its Decision regarding Hydro One 
Networks’ distribution rate application for 2010 and 2011. As part 
of this decision, the OEB also approved the distribution-related OEB 
Cost Assessment Differential Account to record the difference between 
the amounts approved in rates and actual expenditures with respect 
to the OEB’s cost assessments. In March 2015, the OEB approved 
the disposition of the OEB Cost Assessment Differential Account at 
December 31, 2013, including accrued interest, which will be 
recovered through the 2015-2017 Rate Rider. In addition, the OEB 
also approved Hydro One’s request to discontinue this deferral 
account, and there were no additions to this regulatory account in 
2015. 

External Revenue Variance 

In May 2009, the OEB approved forecasted amounts related to 
export service revenue, external revenue from secondary land use, 
and external revenue from station maintenance and engineering and 
construction work. In November 2012, the OEB again approved 
forecasted amounts related to these revenue categories and extended 
the scope to encompass all other external revenues. The external 
revenue variance account balance reflects the excess of actual 
external revenues compared to the OEB-approved forecasted 
amounts. 

Green Energy Expenditure Variance 

In April 2010, the OEB requested the establishment of deferral 
accounts which capture the difference between the revenue recorded 
on the basis of Green Energy Plan expenditures incurred and the 
actual recoveries received.

1	  The unrealized mark-to-market loss relates to $50 million of the Series 33 notes due 2020 (2014 – $250 million of the Series 21 notes due 2015). The 

unrealized mark-to-market loss is offset by a $1 million (2014 – $2 million) unrealized mark-to-market gain on the related fixed-to-floating interest-rate swap 
agreements, which are accounted for as fair value hedges. See Note 13 – Fair Value of Financial Instruments and Risk Management for details of fair value 
hedges. 

2  The interest rates of the floating-rate notes are referenced to the 3-month Canadian dollar bankers’ acceptance rate, plus a margin. 

In 2015, Hydro One Inc. issued $350 million (2014 – $628 
million) of long-term debt under the MTN Program, and repaid $550 
million of long-term debt MTN Program notes (2014 – $750 million). 

Long-term debt totalling $35 million assumed by Hydro One Inc. as 
part of the Haldimand Hydro and Woodstock Hydro acquisitions 
was repaid in 2015. 

The long-term debt is unsecured and denominated in Canadian 
dollars. The long-term debt is summarized by the number of years to 
maturity in Note 13 – Fair Value of Financial Instruments and Risk 
Management. 

13.  Fair Value of Financial Instruments and Risk 

Management 

Fair value is considered to be the exchange price in an orderly 
transaction between market participants to sell an asset or transfer a 
liability at the measurement date. The fair value definition focuses on 
an exit price, which is the price that would be received in the sale of 
an asset or the amount that would be paid to transfer a liability. 

Hydro One classifies its fair value measurements based on the 
following hierarchy, as prescribed by the accounting guidance for

fair value, which prioritizes the inputs to valuation techniques used to 
measure fair value into three levels:
 

Level 1 inputs are unadjusted quoted prices in active markets for
 
identical assets or liabilities that Hydro One has the ability to access.
 
An active market for the asset or liability is one in which transactions
 
for the asset or liability occur with sufficient frequency and volume to
 
provide ongoing pricing information.
 

Level 2 inputs are those other than quoted market prices that are
 
observable, either directly or indirectly, for an asset or liability.
 
Level 2 inputs include, but are not limited to, quoted prices for similar
 
assets or liabilities in an active market, quoted prices for identical or
 
similar assets or liabilities in markets that are not active and inputs
 
other than quoted market prices that are observable for the asset or
 
liability, such as interest-rate curves and yield curves observable at
 

commonly quoted intervals, volatilities, credit risk and default rates. A 
Level 2 measurement cannot have more than an insignificant portion 
of the valuation based on unobservable inputs. 

Level 3 inputs are any fair value measurements that include 
unobservable inputs for the asset or liability for more than an 
insignificant portion of the valuation. A Level 3 measurement may be 
based primarily on Level 2 inputs. 

Non-Derivative Financial Assets and Liabilities 

At December 31, 2015 and 2014, the Company’s carrying 
amounts of accounts receivable, due from related parties, cash and 
cash equivalents, bank indebtedness, short-term notes payable, 
accounts payable, and due to related parties are representative of 
fair value because of the short-term nature of these instruments. 

Fair Value Measurements of Long-Term Debt

1	  The fair value of the $50 million MTN Series 33 notes and $250 million of the MTN Series 21 notes subject to hedging is primarily based on changes in the 

present value of future cash flows due to a change in the yield in the swap market for the related swap (hedged risk). 

2	  The fair value of other notes and debentures, and the portion of the MTN Series 21 notes that are not subject to hedging, represents the market value of the 

notes and debentures and is based on unadjusted period-end market prices for the same or similar debt of the same remaining maturities. 

Fair Value Measurements of Derivative 
Instruments 

At December 31, 2015, the Company had no interest-rate swaps 
classified as undesignated contracts (2014 – $409 million). 

As part of the Norfolk Power and Woodstock Hydro acquisitions, 
Hydro One Inc. assumed liabilities associated with unrealized losses 
on derivative instruments (interest-rate swaps) totalling $6 million. 
Hydro One Inc. extinguished the interest rate swaps and repaid these 
liabilities in 2015. 

At December 31, 2015, Hydro One Inc. had an interest-rate swap 
in the amount of $50 million (2014 – $250 million) that was used to 
convert fixed-rate debt to floating-rate debt. This swap is classified as 
a fair value hedge. Hydro One Inc.’s fair value hedge exposure was 
equal to about 1% (2014 – 3%) of its total long-term debt of $8,724 
million (2014 – $8,925 million). At December 31, 2015, Hydro 
One Inc.’s interest-rate swap designated as a fair value hedge was 
as follows: 

•	  a $50 million fixed-to-floating interest-rate swap agreement to 
convert $50 million of the $350 million MTN Series 33 notes 
maturing April 30, 2020 into three-month variable rate debt.

Cash and cash equivalents include cash and short-term investments. 
The carrying values are representative of fair value because of the 
short-term nature of these instruments. 

There were no significant transfers between any of the fair value 
levels during the years ended December 31, 2015 and 2014. 

The fair value of the derivative instruments is determined using inputs 
other than quoted prices that are observable for these assets. The fair 
value is primarily based on the present value of future cash flows 
using a swap yield curve to determine the assumptions for interest 
rates. 

The fair value of the hedged portion of the long-term debt is primarily 
based on the present value of future cash flows using a swap yield 
curve to determine the assumption for interest rates. The fair value of 
the unhedged portion of the long-term debt is based on unadjusted 
period-end market prices for the same or similar debt of the same 
remaining maturities. 

Risk Management 

Exposure to market risk, credit risk and liquidity risk arises in the 
normal course of the Company’s business. 

Market Risk 

Market risk refers primarily to the risk of loss that results from changes 
in costs, foreign exchange rates and interest rates. The Company is 
exposed to fluctuations in interest rates as its regulated return on 
equity is derived using a formulaic approach that takes into account 
anticipated interest rates, but is not currently exposed to material 
commodity price risk or material foreign exchange risk.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS 

The OEB-approved adjustment formula for calculating return on equity 
in a deemed regulatory capital structure of 60% debt and 40% equity 
provides for increases and decreases depending on changes in 
benchmark rates of return for Government of Canada debt. The 
Company estimates that a 1% decrease in the forecasted long-term 
Government of Canada bond yield used in determining its rate of 
return would reduce the Company’s transmission business’ 2015 net 
income by approximately $20 million (2014 – $20 million) and its 
distribution business’ 2015 net income by approximately $13 million 
(2014 – $10 million). The Company’s net income is adversely 
impacted by rising interest rates as the Company’s maturing long-term 
debt is refinanced at market rates. The Company periodically utilizes 
interest rate swap agreements to mitigate elements of interest rate risk. 

The Company uses a combination of fixed and variable-rate debt to 
manage the mix of its debt portfolio. The Company also uses 
derivative financial instruments to manage interest-rate risk. The 
Company utilizes interest-rate swaps, which are typically designated 
as fair value hedges, as a means to manage its interest rate exposure 

to achieve a lower cost of debt. In addition, the Company may 
utilize interest-rate derivative instruments to lock in interest-rate levels in 
anticipation of future financing. 

A hypothetical 10% increase in the interest rates associated with 
variable-rate debt would not have resulted in a significant decrease in 
Hydro One’s net income for the years ended December 31, 2015 or 
2014. 

Fair Value Hedges 

For derivative instruments that are designated and qualify as fair value 
hedges, the gain or loss on the derivative as well as the offsetting loss 
or gain on the hedged item attributable to the hedged risk are 
recognized in the Consolidated Statements of Operations and 
Comprehensive Income. The net unrealized loss (gain) on the hedged 
debt and the related interest-rate swaps for the years ended 
December 31, 2015 and 2014 are included in financing charges 
as follows: 

Year ended December 31 
(millions of Canadian dollars) 

Unrealized loss (gain) on hedged debt 
Unrealized loss (gain) on fair value interest-rate swaps 

Net unrealized loss (gain) 

At December 31, 2015, Hydro One had $50 million (2014 – 
$250 million) of notional amounts of fair value hedges outstanding 
related to interest-rate swaps, with assets at fair value of $1 million 
(2014 – $2 million). During the years ended December 31, 2015 
and 2014, there was no significant impact on the results of 
operations as a result of any ineffectiveness attributable to fair value 
hedges. 

Credit Risk 

Financial assets create a risk that a counterparty will fail to discharge 
an obligation, causing a financial loss. At December 31, 2015 and 
2014, there were no significant concentrations of credit risk with 
respect to any class of financial assets. The Company’s revenue is 
earned from a broad base of customers. As a result, Hydro One did 
not earn a significant amount of revenue from any single customer. At 
December 31, 2015 and 2014, there was no significant accounts 
receivable balance due from any single customer. 

At December 31, 2015, the Company’s provision for bad debts was 
$61 million (2014 – $66 million). Adjustments and write-offs were 
determined on the basis of a review of overdue accounts, taking into 
consideration historical experience. At December 31, 2015, 
approximately 6% (2014 – 6%) of the Company’s net accounts 
receivable were aged more than 60 days.

Hydro One manages its counterparty credit risk through various 
techniques including: entering into transactions with highly-rated 
counterparties; limiting total exposure levels with individual 
counterparties consistent with the Company’s Board-approved Credit 
Risk Policy; entering into master agreements which enable net 
settlement and the contractual right of offset; and monitoring the 
financial condition of counterparties. In addition to payment netting 
language in master agreements, the Company establishes credit 
limits, margining thresholds and collateral requirements for each 
counterparty. Counterparty credit limits are based on an internal 
credit review that considers a variety of factors, including the results of 
a scoring model, leverage, liquidity, profitability, credit ratings and 
risk management capabilities. The determination of credit exposure 
for a particular counterparty is the sum of current exposure plus the 
potential future exposure with that counterparty. The current exposure 
is calculated as the sum of the principal value of money market 
exposures and the market value of all contracts that have a positive 
mark-to-market position on the measurement date. The Company 
would offset the positive market values against negative values with 
the same counterparty only where permitted by the existence of a 
legal netting agreement such as an International Swap Dealers 
Association master agreement. The potential future exposure 
represents a safety margin to protect against future fluctuations of 
interest rates, currencies, equities, and commodities. It is calculated 

based on factors developed by the Bank of International Settlements, 
following extensive historical analysis of random fluctuations of interest 
rates and currencies. To the extent that a counterparty’s margining 
thresholds are exceeded, the counterparty is required to post 
collateral with the Company as specified in each agreement. The 
Company monitors current and forward credit exposure to 
counterparties both on an individual and an aggregate basis. The 
Company’s credit risk for accounts receivable is limited to the 
carrying amounts on the Consolidated Balance Sheets. 

Liquidity Risk 

Liquidity risk refers to the Company’s ability to meet its financial 
obligations as they come due. Hydro One meets its short-term 
liquidity requirements using cash and cash equivalents on hand, funds 
from operations, the issuance of commercial paper, and the revolving 
standby facilities totaling $2,550 million. The short-term liquidity 
under the Commercial Paper Program, and anticipated levels of funds 
from operations should be sufficient to fund normal operating 
requirements. 

Derivative financial instruments result in exposure to credit risk since 
there is a risk of counterparty default. The credit exposure of 
derivative contracts, before collateral, is represented by the fair value 
of contracts at the reporting date. At December 31, 2015, the 
counterparty credit risk exposure on the fair value of these interest-rate 
swap contracts was $1 million (2014 – $3 million). At 
December 31, 2015, Hydro One’s credit exposure for all derivative 
instruments, and applicable payables and receivables, had a credit 
rating of investment grade, with one financial institution as the 
counterparty. 

At December 31, 2015, accounts payable and accrued liabilities in

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS 

14.  Capital Management	 

The Company’s objectives with respect to its capital structure are to 
maintain effective access to capital on a long-term basis at 
reasonable rates, and to deliver appropriate financial returns. In 
order to ensure ongoing access to capital, the Company targets to 

maintain strong credit quality. The Company considers its capital 
structure to consist of shareholders’ equity, including preferred shares, 
long-term debt, short-term notes payable, and cash and cash 
equivalents. At December 31, 2015 and 2014, the Company’s 
capital structure was as follows: 

December 31 
(millions of Canadian dollars) 

Long-term debt payable within one year 
Short-term notes payable 
Less: cash and cash equivalents

Hydro One Inc. has customary covenants typically associated with 
long-term debt. Among other things, Hydro One Inc.’s long-term debt 
and credit facility covenants limit the permissible debt to 75% of its 
total capitalization, limit the ability to sell assets and impose a 
negative pledge provision, subject to customary exceptions. At 
December 31, 2015 and 2014, Hydro One Inc. was in compliance 
with all of these covenants and limitations. 

15.  Pension and Post-retirement and 
Post-Employment Benefits 

Hydro One has a defined benefit pension plan, a supplementary 
pension plan, and post-retirement and post-employment benefit plans. 
The defined benefit pension plan (Pension Plan) is contributory and 
covers all regular employees of Hydro One and its subsidiaries, 
except employees of Haldimand Hydro and Woodstock Hydro. 
Employees of Haldimand Hydro and Woodstock Hydro participate 
in the OMERS Plan. The supplementary pension plan provides 
members of the Pension Plan with benefits that would have been 
earned and payable under the Pension Plan but for limitations 
imposed by the Income Tax Act (Canada). The supplementary 
pension plan obligation is included with other post-retirement and 
post-employment benefit obligations on the Consolidated Balance 
Sheets. 

The OMERS Plan 

Hydro One contributions to the OMERS Plan for the year ended 
December 31, 2015 were $2 million (2014 – $2 million). At 

December 31, 2015, Company contributions payable included in 
accrued liabilities on the Consolidated Balance Sheets were less than 
$1 million (2014 – less than $1 million). Hydro One contributions do 
not represent more than 5% of total contributions to the OMERS Plan, 
as indicated in OMERS’ most recently available annual report for the 
year ended December 31, 2014. 

At December 31, 2014, the OMERS Plan was 90.8% funded, with 
an unfunded liability of $7.1 billion. This unfunded liability could 
result in future payments by participating employers and members. 
Hydro One future contributions could be increased substantially if 
other entities withdraw from the plan. 

Pension Plan, Post-Retirement and Post-
Employment Plans 

The Pension Plan provides benefits based on highest three-year 
average pensionable earnings. For new management employees 
who commenced employment on or after January 1, 2004, and for 
new Society of Energy Professionals-represented staff hired after 
November 17, 2005, benefits are based on highest five-year 
average pensionable earnings. After retirement, pensions are indexed 
to inflation. 

Company and employee contributions to the Pension Plan are based 
on actuarial valuations performed at least every three years. Annual 
Pension Plan contributions for 2015 of $177 million (2014 – 
$174 million) were based on an actuarial valuation effective 
December 31, 2013 and the expected level of pensionable 

80  ANNUAL REPORT 2015  HYDRO ONE LIMITED 

TSX: H 

earnings. Estimated annual Pension Plan contributions for 2016 are 
approximately $180 million, based on the actuarial valuation as at 
December 31, 2013 and projected levels of pensionable earnings. 
Future minimum contributions beyond 2016 will be based on an 
actuarial valuation effective no later than December 31, 2016. 
Contributions are payable one month in arrears. All of the 
contributions are expected to be in the form of cash. 

Hydro One recognizes the overfunded or underfunded status of the 
Pension Plan, and post-retirement and post-employment benefit plans 
(Plans) as an asset or liability on its Consolidated Balance Sheets, 
with offsetting regulatory assets and liabilities as appropriate. The 
underfunded benefit obligations for the Plans, in the absence of 
regulatory accounting, would be recognized in AOCI. The impact of 
changes in assumptions used to measure pension, post-retirement and 
post-employment benefit obligations is generally recognized over the 
expected average remaining service period of the employees. The 
measurement date for the Plans is December 31.

The funded or unfunded status of the pension, post-retirement and 
post-employment benefit plans refers to the difference between the fair 
value of plan assets and the projected benefit obligations for the 

Plans. The funded/unfunded status changes over time due to several 
factors, including contribution levels, assumed discount rates and 
actual returns on plan assets.

Assumptions 

The measurement of the obligations of the Plans and the costs of 
providing benefits under the Plans involves various factors, including 
the development of valuation assumptions and accounting policy 
elections. When developing the required assumptions, the Company 
considers historical information as well as future expectations. The 
measurement of benefit obligations and costs is impacted by several 

assumptions including the discount rate applied to benefit obligations, 
the long-term expected rate of return on plan assets, Hydro One’s 
expected level of contributions to the Plans, the incidence of mortality, 
the expected remaining service period of plan participants, the level 
of compensation and rate of compensation increases, employee age, 
length of service, and the anticipated rate of increase of health care 
costs, among other factors. The impact of changes in assumptions 

82  ANNUAL REPORT 2015  HYDRO ONE LIMITED 

TSX: H 

used to measure the obligations of the Plans is generally recognized 
over the expected average remaining service period of the plan 
participants. In selecting the expected rate of return on plan assets, 
Hydro One considers historical economic indicators that impact asset 
returns, as well as expectations regarding future long-term capital 

market performance, weighted by target asset class allocations. In 
general, equity securities, real estate and private equity investments 
are forecasted to have higher returns than fixed-income securities. 

The following weighted average assumptions were used to determine 
the benefit obligations at December 31, 2015 and 2014:

2031) 

The discount rate used to determine the current year pension 
obligation and the subsequent year’s net periodic benefit costs is 
based on a yield curve approach. Under the yield curve approach, 
expected future benefit payments for each plan are discounted by a 

rate on a third party bond yield curve corresponding to each 
duration. The yield curve is based on “AA” long-term corporate 
bonds. A single discount rate is calculated that would yield the same 
present value as the sum of the discounted cash flows.

Pension Plan Assets 

Investment Strategy 

On a regular basis, Hydro One evaluates its investment strategy to 
ensure that Pension Plan assets will be sufficient to pay Pension Plan 
benefits when due. As part of this ongoing evaluation, Hydro One 
may make changes to its targeted asset allocation and investment 
strategy. The Pension Plan is managed at a net asset level. The main 
objective of the Pension Plan is to sustain a certain level of net assets 
in order to meet the pension obligations of the Company. The 
Pension Plan fulfills its primary objective by adhering to specific 
investment policies outlined in its Summary of Investment Policies and 

Procedures (SIPP), which is reviewed and approved by the Human 
Resource Committee of Hydro One’s Board of Directors. The 
Company manages net assets by engaging knowledgeable external 
investment managers who are charged with the responsibility of 
investing existing funds and new funds (current year’s employee and 
employer contributions) in accordance with the approved SIPP. The 
performance of the managers is monitored through a governance 
structure. Increases in net assets are a direct result of investment 
income generated by investments held by the Pension Plan and 
contributions to the Pension Plan by eligible employees and by the 
Company. The main use of net assets is for benefit payments to 
eligible Pension Plan members. 

Pension Plan Asset Mix 

At December 31, 2015, the Pension Plan target asset allocations and weighted average asset allocations were as follows: 

Equity securities 
Debt securities 
Other1 

1  Other investments include real estate and infrastructure investments. 

At December 31, 2015, the Pension Plan held $9 million Hydro 
One corporate bonds (2014 – $nil) and $420 million of debt 
securities of the Province (2014 – $340 million). 

Concentrations of Credit Risk 

Hydro One evaluated its Pension Plan’s asset portfolio for the 
existence of significant concentrations of credit risk as at 
December 31, 2015 and 2014. Concentrations that were evaluated 
include, but are not limited to, investment concentrations in a single 
entity, concentrations in a type of industry, and concentrations in 
individual funds. At December 31, 2015 and 2014, there were no

significant concentrations (defined as greater than 10% of plan assets) 
of risk in the Pension Plan’s assets. 

The Pension Plan manages its counterparty credit risk with respect to 
bonds by investing in investment-grade and government bonds and 
with respect to derivative instruments by transacting only with financial 
institutions rated at least “A+” by Standard & Poor’s Rating Services, 
DBRS Limited, and Fitch Ratings Inc., and “A1” by Moody’s Investors 
Service, and also by utilizing exposure limits to each counterparty 
and ensuring that exposure is diversified across counterparties. The 
risk of default on transactions in listed securities is considered 
minimal, as the trade will fail if either party to the transaction does not 
meet its obligation.

Changes in the Fair Value of Financial 
Instruments Classified in Level 3 

The following table summarizes the changes in fair value of financial 
instruments classified in Level 3 for the years ended December 31, 
2015 and 2014. The Pension Plan classifies financial instruments as 

Level 3 when the fair value is measured based on at least one 
significant input that is not observable in the markets or due to lack of 
liquidity in certain markets. The gains and losses presented in the 
table below may include changes in fair value based on both 
observable and unobservable inputs.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS 

There were no significant transfers between any of the fair value 
levels during the years ended December 31, 2015 and 2014. 

The Company performs sensitivity analysis for fair value measurements 
classified in Level 3, substituting the unobservable inputs with one or 
more reasonably possible alternative assumptions. These sensitivity 
analyses resulted in negligible changes in the fair value of financial 
instruments classified in this level. 

Valuation Techniques Used to Determine Fair 
Value 
Pooled Funds 

The pooled fund category mainly consists of private equity, real 
estate and infrastructure investments. Private equity investments 
represent private equity funds that invest in operating companies that 
are not publicly traded on a stock exchange. Investment strategies in 
private equity include limited partnerships in businesses that are 
characterized by high internal growth and operational efficiencies, 
venture capital, leveraged buyouts and special situations such as 
distressed investments. Real estate and infrastructure investments 
represent funds that invest in real assets which are not publicly traded 
on a stock exchange. Investment strategies in real estate include 
limited partnerships that seek to generate a total return through 
income and capital growth by investing primarily in global and 
Canadian limited partnerships. Investment strategies in infrastructure 
include limited partnerships in core infrastructure assets focusing on 
assets that generate stable, long-term cash flows and deliver 
incremental returns relative to conventional fixed-income investments. 
Private equity, real estate and infrastructure valuations are reported by 
the fund manager and are based on the valuation of the underlying 
investments which includes inputs such as cost, operating results, 
discounted future cash flows and market-based comparable data. 
Since these valuation inputs are not highly observable, private equity 
and infrastructure investments have been categorized as Level 3 
within pooled funds.

Cash Equivalents 

Demand cash deposits held with banks and cash held by the 
investment managers are considered cash equivalents and are 
included in the fair value measurements hierarchy as Level 1. 

Short-Term Securities 

Short-term securities are valued at cost plus accrued interest, which 
approximates fair value due to their short-term nature. Short-term 
securities have been categorized as Level 2. 

Real Estate 

Real estate investments represent investments in holding companies 
that invest in real estate properties. The investments in the holding 
companies are valued using net asset values reported by the fund 
manager. Real estate investments are categorized as Level 3. 

Corporate Shares 

Corporate shares are valued based on quoted prices in active 
markets and are categorized as Level 1. Investments denominated in 
foreign currencies are translated into Canadian currency at year-end 
rates of exchange. 

Bonds and Debentures 

Bonds and debentures are presented at published closing trade 
quotations, and are categorized as Level 2.

Hydro One records a liability for the estimated future expenditures for 
land assessment and remediation and for the phase-out and 
destruction of PCB-contaminated mineral oil removed from electrical 
equipment when it is determined that future environmental remediation 
expenditures are probable under existing statute or regulation and the 
amount of the future expenditures can be reasonably estimated. 

There are uncertainties in estimating future environmental costs due to 
potential external events such as changes in legislation or regulations, 
and advances in remediation technologies. In determining the 
amounts to be recorded as environmental liabilities, the Company 
estimates the current cost of completing required work and makes 
assumptions as to when the future expenditures will actually be

incurred, in order to generate future cash flow information. A long­
term inflation rate assumption of approximately 2% has been used to 
express these current cost estimates as estimated future expenditures. 
Future expenditures have been discounted using factors ranging from 
approximately 2.0% to 6.3%, depending on the appropriate rate for 
the period when expenditures are expected to be incurred. All factors 
used in estimating the Company’s environmental liabilities represent 
management’s best estimates of the present value of costs required to 
meet existing legislation or regulations. However, it is reasonably 
possible that numbers or volumes of contaminated assets, cost 
estimates to perform work, inflation assumptions and the assumed 
pattern of annual cash flows may differ significantly from the 
Company’s current assumptions. In addition, with respect to the PCB 
environmental liability, the availability of critical resources such as 
skilled labour and replacement assets and the ability to take 
maintenance outages in critical facilities may influence the timing of 
expenditures. 

PCBs 

The Environment Canada regulations, enacted under the Canadian 
Environmental Protection Act, 1999, govern the management, 
storage and disposal of PCBs based on certain criteria, including 
type of equipment, in-use status, and PCB-contamination thresholds. 
Under current regulations, Hydro One’s PCBs have to be disposed of 
by the end of 2025, with the exception of specifically exempted 
equipment. Contaminated equipment will generally be replaced, or 
will be decontaminated by removing PCB-contaminated insulating oil 
and retro filling with replacement oil that contains PCBs in 
concentrations of less than 2 ppm. 

The Company’s best estimate of the total estimated future 
expenditures to comply with current PCB regulations is $168 million 
(2014 – $195 million). These expenditures are expected to be 
incurred over the period from 2016 to 2025. As a result of its annual 
review of environmental liabilities, the Company recorded a 
revaluation adjustment in 2015 to reduce the PCB environmental 
liability by $24 million (2014 – $33 million). 

Land Assessment and Remediation 

The Company’s best estimate of the total estimated future 
expenditures to complete its land assessment and remediation 
program is $61 million (2014 –$70 million). These expenditures are 
expected to be incurred over the period from 2016 to 2023. As a 
result of its annual review of environmental liabilities, the Company 
recorded a revaluation adjustment in 2015 to increase the land 
assessment and remediation environmental liability by $1 million 
(2014 – $13 million).

17.  Asset Retirement Obligations 

Hydro One records a liability for the estimated future expenditures for 
the removal and disposal of asbestos-containing materials installed in 
some of its facilities and for the decommissioning of specific switching 
stations located on unowned sites. Asset retirement obligations, which 
represent legal obligations associated with the retirement of certain 
tangible long-lived assets, are computed as the present value of the 
projected expenditures for the future retirement of specific assets and 
are recognized in the period in which the liability is incurred, if a 
reasonable estimate of fair value can be made. If the asset remains in 
service at the recognition date, the present value of the liability is 
added to the carrying amount of the associated asset in the period 
the liability is incurred and this additional carrying amount is 
depreciated over the remaining life of the asset. If an asset retirement 
obligation is recorded in respect of an out-of-service asset, the asset 
retirement cost is charged to results of operations. Subsequent to the 
initial recognition, the liability is adjusted for any revisions to the 
estimated future cash flows associated with the asset retirement 
obligation, which can occur due to a number of factors including, but 
not limited to, cost escalation, changes in technology applicable to 
the assets to be retired, changes in legislation or regulations, as well 
as for accretion of the liability due to the passage of time until the 
obligation is settled. Depreciation expense is adjusted prospectively 
for any increases or decreases to the carrying amount of the 
associated asset. 

In determining the amounts to be recorded as asset retirement 
obligations, the Company estimates the current fair value for 
completing required work and makes assumptions as to when the 
future expenditures will actually be incurred, in order to generate 
future cash flow information. A long-term inflation assumption of 
approximately 2% has been used to express these current cost 
estimates as estimated future expenditures. Future expenditures have 
been discounted using factors ranging from approximately 3.0% to 
5.0%, depending on the appropriate rate for the period when 
expenditures are expected to be incurred. All factors used in 
estimating the Company’s asset retirement obligations represent 
management’s best estimates of the cost required to meet existing 
legislation or regulations. However, it is reasonably possible that 
numbers or volumes of contaminated assets, cost estimates to perform 
work, inflation assumptions and the assumed pattern of annual cash 
flows may differ significantly from the Company’s current assumptions. 
Asset retirement obligations are reviewed annually or more frequently 
if significant changes in regulations or other relevant factors occur. 
Estimate changes are accounted for prospectively. 

At December 31, 2015, Hydro One had recorded asset retirement 
obligations of $9 million (2014 – $9 million), consisting of $8 million 
(2014 – $8 million) related to the estimated future expenditures 
associated with the removal and disposal of asbestos-containing 

materials installed in some of its facilities, as well as $1 million 
(2014 – $1 million) related to the future decommissioning and 
removal of two switching stations. The amount of interest recorded is 
nominal. 

18.  Share Capital 
Common Shares 

The Company is authorized to issue an unlimited number of common 
shares. At December 31, 2015, the Company had 595,000,000 
common shares issued and outstanding. 

The amount and timing of any dividends payable by Hydro One is at 
the discretion of the Hydro One Board of Directors and is established 
on the basis of Hydro One’s results of operations, maintenance of its 
deemed regulatory capital structure, financial condition, cash 
requirements, the satisfaction of solvency tests imposed by corporate 
laws for the declaration and payment of dividends and other factors 
that the Board of Directors may consider relevant. 

Preferred Shares 

The Company is authorized to issue an unlimited number of preferred 
shares, issuable in series. At December 31, 2015, two series of 
preferred shares are authorized for issuance: the Series 1 preferred 
shares and the Series 2 preferred shares. At December 31, 2015, 
the Company had 16,720,000 Series 1 preferred shares and no 
Series 2 preferred shares issued and outstanding. 

Hydro One may from time to time issue preferred shares in one or 
more series. Prior to issuing shares in a series, the Hydro One Board 
of Directors is required to fix the number of shares in the series and 
determine the designation, rights, privileges, restrictions and 
conditions attaching to that series of preferred shares. Holders of 
Hydro One’s preferred shares are not entitled to receive notice of, to 
attend or to vote at any meeting of the shareholders of Hydro One 
except that votes may be granted to a series of preferred shares 
when dividends have not been paid on any one or more series as 
determined by the applicable series provisions. Each series of 
preferred shares ranks on parity with every other series of preferred 
shares, and are entitled to a preference over the common shares and 
any other shares ranking junior to the preferred shares, with respect to 
dividends and the distribution of assets and return of capital in the 
event of the liquidation, dissolution or winding up of Hydro One. 

For the period commencing from the date of issue of the Series 1 
preferred shares and ending on and including November 19, 2020, 
the holders of Series 1 preferred shares are entitled to receive fixed 
cumulative preferential dividends of $1.0625 per share per year, if 
and when declared by the Board of Directors, payable quarterly. The 

dividend rate will reset on November 20, 2020 and every five years 
thereafter at a rate equal to the sum of the then five-year Government 
of Canada bond yield and 3.53%. The Series 1 preferred shares will 
not be redeemable by Hydro One prior to November 20, 2020, but 
will be redeemable by Hydro One on November 20, 2020 and on 
November 20 of every fifth year thereafter at a redemption price 
equal to $25.00 for each Series 1 preferred share redeemed, plus 
any accrued or unpaid dividends. The holders of Series 1 preferred 
shares will have the right, at their option, on November 20, 2020 
and on November 20 of every fifth year thereafter, to convert all or 
any of their Series 1 preferred shares into Series 2 preferred shares 
on a one-for-one basis, subject to certain restrictions on conversion. At 
December 31, 2015, Series 1 preferred dividends of $3 million or 
$0.18 per share were in arrears. 

The holders of Series 2 preferred shares will be entitled to receive 
quarterly floating rate cumulative dividends, if and when declared by 
the Board of Directors, at a rate equal to the sum of the then three-
month Government of Canada treasury bill rate and 3.53% as reset 
quarterly. The Series 2 preferred shares will not be redeemable by 
Hydro One prior to November 20, 2020, but will be redeemable 
by Hydro One at a redemption price equal to $25.00 for each 
Series 2 preferred share redeemed, if redeemed on November 20, 
2025 or on November 20 of every fifth year thereafter, or $25.50 
for each Series 2 preferred share redeemed, if redeemed on any 
other date after November 20, 2020, in each case plus any 
accrued or unpaid dividends. The holders of Series 2 preferred 
shares will have the right, at their option, on November 20, 2025 
and on November 20 of every fifth year thereafter, to convert all or 
any of their Series 2 preferred shares into Series 1 preferred shares 
on a one-for-one basis, subject to certain restrictions on conversion. 

Prior to October 31, 2015, the Company had 12,920,000 issued 
and outstanding 5.5% cumulative preferred shares held by the 
Province, with a redemption value of $25 per share or $323 million 
total value. These preferred shares were entitled to an annual 
cumulative dividend of $18 million, or $1.375 per share, which was 
payable on a quarterly basis. These preferred shares had conditions 
for their redemption that were outside the control of the Company 
because the Province could exercise its right to redeem in the event of 
change in ownership without approval of the Company’s Board of 
Directors. At December 31, 2014, these preferred shares were 
classified on the Consolidated Balance Sheet as temporary equity 
because the redemption feature was outside the control of the 
Company. On October 31, 2015, these preferred shares were 
purchased and cancelled by Hydro One Inc. See “Reorganization” 
below for further details.

Province and issuing new common shares and preferred shares to the 
Province. 

The following tables present the changes to common and preferred 
shares as a result of Pre-IPO Transactions, as well as the movement in 
the number of common and preferred shares during the year ended 
December 31, 2015. There was no movement in common or

(a) At January 1, 2015, all common and preferred shares represent the shares of Hydro One Inc. 

(b) On August 31, 2015, Hydro One was incorporated under the Business Corporations Act (Ontario) and issued 100,000 common shares to the Province for 

proceeds of $100,000. 

(c)  On October 31, 2015, Hydro One Inc. purchased and cancelled 12,920,000 preferred shares of Hydro One Inc. previously held by the Province for 

cancellation at a price equal to the redemption price of the preferred shares totaling $323 million, which was satisfied by the issuance to the Province of 
2,640 common shares of Hydro One Inc. 

(d) On October 31, 2015, all of the issued and outstanding common shares of Hydro One Inc. were acquired by Hydro One from the Province in return for 

12,197,500,000 common shares of Hydro One and 16,720,000 Series 1 preferred shares of Hydro One. 

(e) On November 4, 2015, Hydro One issued 2.6 billion common shares to the Province for proceeds of $2.6 billion. 

(f)  On November 4, 2015, the common shares of Hydro One were consolidated by way of articles of amendment approved by the Province as sole 

shareholder so that, after such consolidation, 595,000,000 common shares of Hydro One were issued and outstanding. 

Share Ownership Restrictions 

The Electricity Act imposes share ownership restrictions on securities of 
Hydro One carrying a voting right (Voting Securities). These 
restrictions provide that no person or company (or combination of 
persons or companies acting jointly or in concert) may beneficially 
own or exercise control or direction over more than 10% of any class 

or series of Voting Securities, including common shares of the 
Company (Share Ownership Restrictions). The Share Ownership 
Restrictions do not apply to Voting Securities held by the Province, nor 
to an underwriter who holds Voting Securities solely for the purpose of 
distributing those securities to purchasers who comply with the Share 
Ownership Restrictions.

20.  Earnings Per Share 

In 2015, preferred share dividends in the amount of $13 million 
(2014 – $18 million) and common share dividends in the amount of 
$875 million (2014 – $269 million) were declared. 

Basic earnings per common share (EPS) is calculated by dividing net 
income attributable to common shareholders of Hydro One by the 
weighted average number of common shares outstanding. 

In August 2015, Hydro One declared a dividend in-kind on its 
common shares payable in all of the issued and outstanding shares of 
Hydro One Brampton. See Note 4 – Business Combinations. 

Diluted EPS is calculated by dividing net income attributable to 
common shareholders of Hydro One by the weighted average 
number of common shares outstanding adjusted for the effects of 
potentially dilutive share grant plans, which is calculated using the 
treasury stock method.

Pro forma Adjusted non-GAAP Basic and 
Diluted EPS 

The following pro forma adjusted non-GAAP basic and diluted EPS 
has been prepared by management on a supplementary basis which 
assumes that the total number of common shares outstanding was 
595,000,000 in each of the years ended December 31, 2015 and 
2014. The supplementary pro forma disclosure is used internally by 
management subsequent to the IPO of Hydro One to assess the 

Company’s performance and is considered useful because it 
eliminates the impact of the issuance of common shares to the 
Province prior to the IPO. Prior to the IPO, the Province was the sole 
shareholder of Hydro One and disclosure of EPS did not provide 
meaningful information. EPS is considered an important measure and 
management believes that presenting it for all periods based on the 
number of outstanding shares on, and subsequent to, the IPO 
provides users with a basis to evaluate the operations of the 
Company with comparable companies.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS 

21.  Stock-based Compensation 
Share Grant Plans 

At December 31, 2015, Hydro One had two share grant plans, one 
for the benefit of certain members of the Power Workers’ Union (the 
PWU Share Grant Plan) and one for the benefit of certain members 
of The Society of Energy Professionals (the Society Share Grant Plan). 

The PWU Share Grant Plan provides for the issuance of common 
shares of Hydro One from treasury to certain eligible members of the 
Power Workers’ Union annually, commencing on April 1, 2017 and 
continuing until the earlier of April 1, 2028 or the date an eligible 
employee no longer meets the eligibility criteria of the PWU Share 
Grant Plan. To be eligible, an employee must be a member of the 
Pension Plan on April 1, 2015, be employed on the date annual 
share issuance occurs and continue to have under 35 years of 
service. The requisite service period for the PWU share grant plan 
begins on July 3, 2015, which is the date the share grant plans were 
ratified by the PWU. The number of common shares issued annually 
to each eligible employee will be equal to 2.7% of such eligible 
employee’s salary as at April 1, 2015, divided by $20.50, being 
the price of the common shares of Hydro One in the IPO. The 
aggregate number of common shares issuable under the PWU Share 
Grant Plan shall not exceed 3,981,763 common shares. In 2015, 
3,979,062 common shares were granted under the PWU Share 
Grant Plan. 

The Society Share Grant Plan provides for the issuance of common 
shares of Hydro One from treasury to certain eligible members of The 
Society of Energy Professionals annually, commencing on April 1, 
2018 and continuing until the earlier of April 1, 2029 or the date an 
eligible employee no longer meets the eligibility criteria of the Society

Share Grant Plan. To be eligible, an employee must be a member of 
the Pension Plan on September 1, 2015, be employed on the date 
annual share issuance occurs and continue to have under 35 years of 
service. Therefore the requisite service period for the Society Share 
Grant Plan begins on September 1, 2015. The number of common 
shares issued annually to each eligible employee will be equal to 
2.0% of such eligible employee’s salary as at September 1, 2015, 
divided by $20.50, being the price of the common shares of Hydro 
One in the IPO. The aggregate number of common shares issuable 
under the Society Share Grant Plan shall not exceed 1,434,686 
common shares. In 2015, 1,433,292 common shares were granted 
under the Society Share Grant Plan. 

The fair value of the share grants is estimated based on the grant 
date share price of $20.50 and is recognized using the graded-
vesting attribution method as the share grant plans have both a 
performance condition and a service condition. Total fair value of 
shares granted in 2015 is $111 million (2014 – $nil). Total share 
based compensation recognized during 2015 was $10 million 
(2014 – $nil) and was recorded as a regulatory asset. The historical 
turnover rate relating to members of the Power Workers’ Union and 
The Society of Energy Professionals is not believed to be reflective of 
a future turnover rate due to benefits conferred by the share grant 
plans. At December 31, 2015 the Company expects all eligible 
employees to receive the share grants until such time that they no 
longer meet the eligibility criteria and therefore, a forfeiture rate of 0% 
is assumed in amounts recognized during 2015. The Company will 
reevaluate this assumption in subsequent periods based on actual 
experience. 

A summary of share grant activity under the Plan as of December 31, 
2015 is presented below:

Directors’ DSU Plan	 

Under the Company’s Directors’ DSU Plan, directors can elect to 
receive credit for their annual cash retainer in a notional account of 
DSUs in lieu of cash. Hydro One’s Board of Directors may also 

determine from time to time that special circumstances exist that would 
reasonably justify the grant of DSUs to a director as compensation in 
addition to any regular retainer or fee to which the director is entitled. 

94  ANNUAL REPORT 2015  HYDRO ONE LIMITED 

TSX: H 

Each DSU represents a unit with an underlying value equivalent to the 
value of one common share of the Company and is entitled to accrue 

common share dividend equivalents in the form of additional DSUs at 
the time dividends are paid, subsequent to declaration by Hydro 
One’s Board of Directors.

For the year ended December 31, 2015, an expense of less than 
$1 million (2014 – $nil) was recognized in earnings with respect to 
the DSU Plan. At December 31, 2015, a liability of less than $1 
million (December 31, 2014 – $nil), related to outstanding DSUs has 
been recorded at the closing price of the Company’s common shares 
of $22.29 and is included in accrued liabilities on the Balance 
Sheet. 

The LTIP provides flexibility to award a range of vehicles, including 
restricted share units, performance share units, stock options, share 
appreciation rights, restricted shares, deferred share units and other 
share-based awards. The mix of vehicles is intended to vary by role 
to recognize the level of executive accountability for overall business 
performance. No long-term incentives were awarded during 2015. 

Employee Share Ownership Plan 

Effective December 15, 2015, Hydro One established an Employee 
Share Ownership Plan (ESOP). Under the ESOP, certain eligible 
management and non-represented employees may contribute 
between 1% and 6% of their base salary towards purchasing 
common shares of Hydro One. The Company will match 50% of the 
employee’s contributions, up to a maximum Company contribution of 
$25,000 per calendar year. No contributions were made under the 
ESOP during 2015. 

Long-term Incentive Plan 

Effective August 31, 2015, the Board of Directors of Hydro One 
adopted a Long-term Incentive Plan (LTIP). Under the LTIP, long-term 
incentives will be granted to certain executive and management 
employees, and all equity-based awards will be settled in newly-
issued shares of Hydro One from treasury, consistent with the 
provisions of the plan. The aggregate number of shares issuable 
under the LTIP shall not exceed 11,900,000 shares.

22.  Noncontrolling Interest 

On December 16, 2014, the relevant Bruce to Milton Line 
transmission assets totalling $526 million were transferred from Hydro 
One Networks to B2M LP. This was financed by 60% debt ($316 
million) and 40% equity ($210 million). On December 17, 2014, 
the Saugeen Ojibway Nation (SON) acquired a 34.2% equity 
interest in B2M LP for consideration of $72 million, representing the 
fair value of the equity interest acquired. The SON’s initial investment 
in B2M LP consists of $50 million of Class A units and $22 million of 
Class B units. 

The Class B units have a mandatory put option which requires that 
upon the occurrence of an enforcement event (i.e. an event of default 
such as a debt default by the SON or insolvency event), Hydro One 
purchase the Class B units of B2M LP for net book value on the 
redemption date. The noncontrolling interest relating to the Class B 
units is classified on the Consolidated Balance Sheet as temporary 
equity because the redemption feature is outside the control of the 
Company. The balance of the noncontrolling interest is classified 
within equity.

23.  Related Party Transactions 

The Province is the majority shareholder of Hydro One. The OEFC, 
IESO, Ontario Power Generation Inc. (OPG), the OEB, and Hydro 
One Brampton are related parties to Hydro One because they are 
controlled or significantly influenced by the Province. Effective 
January 1, 2015, the OPA and IESO have merged and are now 
operating as IESO. 

The Province 

•  During 2015, Hydro One paid dividends to the Province totalling 
$888 million (2014 – $287 million). In addition, on August 31, 
2015, Hydro One declared a dividend in-kind on its common 
shares payable in all of the issued and outstanding shares of 
Hydro One Brampton. See Note 4 – Business Combinations. 

•  On November 4, 2015, Hydro One issued common shares to 
the Province for proceeds of $2.6 billion. See Note 18 –

these programs. 

OPG 

•  In 2015, Hydro One purchased power in the amount of 

$11 million (2014 – $23 million) from OPG. 

•  Hydro One has service level agreements with OPG. These

telecommunications services. In 2015, revenues related to the 
provision of construction and equipment maintenance services with 
respect to these service level agreements were $7 million (2014 – 
$12 million), primarily for the Transmission Business. Operation, 
maintenance and administration costs in 2015 and 2014 related 
to the purchase of services with respect to these service level 
agreements were not significant. 

OEFC 

•  During 2015, Hydro One Inc. incurred certain IPO related 

expenses totaling $7 million, which will be reimbursed to the 
Company by the Province. 

•  In 2015, Hydro One made PILs to the OEFC totalling $2.9 billion 
(2014 – $86 million), including Departure Tax of $2.6 billion 
(2014 – $nil). 

IESO 

•  In 2015, Hydro One purchased power in the amount of 
$2,318 million (2014 – $2,601 million) from the IESO-
administered electricity market. 

•  Hydro One receives revenues for transmission services from the 
IESO, based on OEB-approved uniform transmission rates. 
Transmission revenues for 2015 include $1,548 million (2014 
– $1,556 million) related to these services. 

•  Hydro One receives amounts for rural rate protection from the 

IESO. Distribution revenues for 2015 include $127 million (2014 
– $127 million) related to this program. 

•  Hydro One also receives revenues related to the supply of 
electricity to remote northern communities from the IESO. 
Distribution revenues for 2015 include $32 million (2014 
– $32 million) related to these services. 

•  The IESO (OPA prior to January 1, 2015) funds substantially all 

of the Company’s CDM programs. The funding includes 
program costs, incentives, and management fees. During 2015, 

96  ANNUAL REPORT 2015  HYDRO ONE LIMITED 

TSX: H 

•  In 2015, Hydro One purchased power in the amount of 

$6 million (2014 – $9 million) from power contracts administered 
by the OEFC. 

•  During 2015, Hydro One paid a $8 million (2014 – $5 million) 
fee to the OEFC for indemnification against adverse claims in 
excess of $10 million paid by the OEFC with respect to certain of 
Ontario Hydro’s businesses transferred to Hydro One on April 1, 
1999. Hydro One has not made any claims under the indemnity 
since it was put in place in 1999. Hydro One and the OEFC, 
with the consent of the Minister of Finance, terminated the 
indemnity fee effective October 31, 2015. 

•  PILs and payments in lieu of property taxes were paid to the 

OEFC. 

OEB 

•  Under the Ontario Energy Board Act, 1998, the OEB is required 
to recover all of its annual operating costs from gas and electricity 
distributors and transmitters. In 2015, Hydro One incurred 
$12 million (2014 – $12 million) in OEB fees. 

Hydro One Brampton 

•  Effective August 31, 2015, Hydro One Brampton is no longer a 
subsidiary of Hydro One, but is indirectly owned by the Province. 
For change in ownership of Hydro One Brampton, see Note 4 – 
Business Combinations. 

•  Subsequent to August 31, 2015, Hydro One continues to provide 

certain management, administrative and smart meter network 
services to Hydro One Brampton pursuant to certain service level 
agreements, which are provided at market rates. These 
agreements will continue until the end of 2016 (except in the case 
of smart meter network services, which will continue until the end 
of 2017). Hydro One Brampton has the right to renew these 
agreements (other than smart meter network services) for additional 
one-year terms to end no later than December 31, 2019. 
Additionally, on August 31, 2015, Hydro One Inc. and Hydro 
One Brampton entered into a license agreement which permits 

Hydro One Brampton to use the “Hydro One” name and related 
licensed marks. These agreements will terminate if the Province 
disposes of its interest in Hydro One Brampton, except in the case 
of the smart meter network services agreement, which is 
anticipated to continue for a transition period after the Province 
disposes of its interest in Hydro One Brampton. During 2015, 
revenues related to the provision of services with respect to these 
service level agreements were $1 million. 

Sales to and purchases from related parties occur at normal market 
prices or at a proxy for fair value based on the requirements of the 
OEB’s Affiliate Relationships Code. Outstanding balances at period 
end are interest free and settled in cash. 

The amounts due to and from related parties as a result of the 
transactions referred to above are as follows:

Capital Contributions 

Hydro One enters into contracts governed by the OEB Transmission 
System Code when a transmission customer requests a new or 
upgraded transmission connection. The customer is required to make 
a capital contribution to Hydro One based on the shortfall between 
the present value of the costs of the connection facility and the present 
value of revenues. The present value of revenues is based on an 
estimate of load forecast for the period of the contract with Hydro 
One. Once the connection facility is commissioned, in accordance 

with the OEB Transmission System Code, Hydro One will periodically 
reassess the estimated of load forecast which will lead to a decrease, 
or an increase in the capital contributions from the customer. The 
increase or decrease in capital contributions is recorded directly to 
fixed assets in service. In 2015, capital contributions from these 
reassessments totalled $62 million, which represents the difference 
between the revised load forecast of electricity transmitted compared 
to the load forecast in the original contract, subject to certain 
adjustments. No reassessments occurred in 2014.

Legal Proceedings 

Hydro One is involved in various lawsuits, claims and regulatory 
proceedings in the normal course of business. In the opinion of 
management, the outcome of such matters will not have a material 
adverse effect on the Company’s consolidated financial position, 
results of operations or cash flows.

In September 2015, Hydro One and three of its subsidiaries were 
served with a class action suit in which the representative plaintiff is 
seeking up to $125 million in damages related to allegations of 
improper billing practices. Hydro One intends to defend the action. 
Due to the preliminary stage of legal proceedings, an estimate of a 
possible loss related to this claim cannot be made. 

Transfer of Assets 

The transfer orders by which the Company acquired certain of 
Ontario Hydro’s businesses as of April 1, 1999 did not transfer title 
to some assets located on Reserves (as defined in the Indian Act 
(Canada)). Currently, the OEFC holds these assets. Under the terms 
of the transfer orders, the Company is required to manage these 
assets until it has obtained all consents necessary to complete the 
transfer of title of these assets to itself. The Company cannot predict 
the aggregate amount that it may have to pay, either on an annual or 
one-time basis, to obtain the required consents. In 2015, the 
Company paid approximately $1 million (2014 – $1 million) in 
respect of consents obtained. If the Company cannot obtain the 
required consents, the OEFC will continue to hold these assets for an 
indefinite period of time. If the Company cannot reach a satisfactory 
settlement, it may have to relocate these assets to other locations at a 
cost that could be substantial or, in a limited number of cases, to 
abandon a line and replace it with diesel-generation facilities. The 
costs relating to these assets could have a material adverse effect on 
the Company’s results of operations if the Company is not able to 
recover them in future rate orders. 

26.  Commitments 
Outsourcing Agreements 

Inergi LP (Inergi), an affiliate of Capgemini Canada Inc., provides 
services to Hydro One, including settlements, source to pay services, 
pay operations services, information technology, finance and 
accounting services. The agreement with Inergi for these services 
expires in December 2019. In addition, Inergi provides customer 
service operations outsourcing services to Hydro One. The agreement 
for these services expires in February 2018. 

Brookfield Global Integrated Solutions (formerly Brookfield Johnson 
Controls Canada LP) (Brookfield) provides services to Hydro One, 
including facilities management and execution of certain capital 
projects as deemed required by the Company. The current 
agreement with Brookfield expires in December 2024. 

At December 31, 2015, the annual commitments under the 
outsourcing agreements were as follows: 2016 – $167 million; 
2017 – $138 million; 2018 – $106 million; 2019 – $99 million; 
2020 – $2 million; and thereafter – $11 million. 

Trilliant Agreement 

In December 2015, Hydro One entered into an agreement with 
Trilliant Holdings Inc. and Trilliant Networks (Canada) Inc. (Trilliant) 
for the supply, maintenance and support services for smart meters and 
related hardware and software, including additional software 

licenses,  as  well  as  certain  professional  services.  This  agreement  is  
for  a  term  of  ten  years,  from  December  31,  2015  to  December  31,  
2025,  with  the  option  to  renew  for  an  additional  term  of  five  years  at  
Hydro  One’s  sole  discretion.  At  December  31,  2015,  the  annual  
commitments  under  the  agreement  were  as  follows:  2016  –  
$17  million;  2017  –  $17  million;  2018  –  $17  million;  2019  –  
$17  million;  2020  –  $16  million;  and  thereafter  –  $6  million.  

Prudential Support 

Purchasers  of  electricity  in  Ontario,  through  the  IESO,  are  required  to  
provide  security  to  mitigate  the  risk  of  their  default  based  on  their  
expected  activity  in  the  market.  As  at  December  31,  2015,  Hydro  
One  Inc.  provided  prudential  support  to  the  IESO  on  behalf  of  its  
subsidiaries  using  parental  guarantees  of  $329  million  (2014  –  
$330  million),  and  on  behalf  of  a  distributor  using  guarantees  of  
$1  million  (2014  –  $1  million).  In  addition,  as  at  December  31,  
2015,  Hydro  One  Inc.  has  provided  letters  of  credit  in  the  amount  of  
$15  million  (2014  –  $8  million)  to  the  IESO.  The  IESO  could  draw  
on  these  guarantees  and/or  letters  of  credit  if  these  subsidiaries  or  
distributor  fail  to  make  a  payment  required  by  a  default  notice  issued  
by  the  IESO.  The  maximum  potential  payment  is  the  face  value  of  any  
letters  of  credit  plus  the  amount  of  the  parental  guarantees.  

Retirement Compensation Arrangements 

Bank letters of credit have been issued to provide security for Hydro 
One Inc.’s liability under the terms of a trust fund established pursuant 
to the supplementary pension plan for eligible employees of Hydro 
One Inc. The supplementary pension plan trustee is required to draw 
upon these letters of credit if Hydro One Inc. is in default of its 
obligations under the terms of this plan. Such obligations include the 
requirement to provide the trustee with an annual actuarial report as 
well as letters of credit sufficient to secure Hydro One Inc.’s liability 
under the plan, to pay benefits payable under the plan and to pay 
the letter of credit fee. The maximum potential payment is the face 
value of the letters of credit. At December 31, 2015, Hydro One 
Inc. had letters of credit of $139 million (2014 – $126 million) 
outstanding relating to retirement compensation arrangements. 

Operating Leases 

Hydro One is committed as lessee to irrevocable operating lease 
contracts for buildings used in administrative and service-related 
functions and storing telecommunications equipment. These leases 
have typical terms of between three and five years, but several leases 
have lesser or greater terms to address special circumstances and/or  
opportunities. Renewal options, which are generally prevalent in most 
leases, have similar terms of three to five years. All leases include a 
clause to enable upward revision of the rental charge on an annual

•  Other Business, which includes certain corporate activities and the 

operations of the Company’s telecommunications business. 

The designation of segments has been based on a combination of 
regulatory status and the nature of the products and services 
provided. Operating segments of the Company are determined 
based on information used by the chief operating decision maker in 
deciding how to allocate resources and evaluate the performance of 
each of the segments. The Company evaluates segment performance 
based on income before financing charges and income taxes from 
continuing operations (excluding certain allocated corporate 
governance costs). 

The accounting policies followed by the segments are the same as 
those described in the summary of significant accounting policies (see 
Note 2 – Significant Accounting Policies). Segment information on the 
above basis is as follows:
