We are at a time of immense change and excitement 
in our industry. The power grid of the 21st century will 
look very different from what we have seen in the past, 
offering cleaner and more affordable energy. Renewables 
are increasingly cost competitive and have become the 
dominant type of new build generation in most of our 
markets. Existing thermal generation and energy storage 
will become more integrated with newer renewable 
sources to meet challenges posed by the intermittent 
nature of wind and solar generation. We also see a 
growing demand for natural gas, with the potential for 
gas to replace oil-fired generation in several markets. 

Our actions over the past several years have put AES in a great position to 
be a premier provider of energy solutions across our markets during this 
time of immense change. As we seek to meet the evolving needs of our 
energy customers, we benefit from a strong balance sheet, a unique and 
diverse global platform, proven success in deploying new technologies and a 
talented global workforce. 

In 2016 we expanded our renewables portfolio and grew our world-leading 
battery-based energy storage business. We began selling our proprietary 
Advancion® storage platform to utilities and other customers. We have 
now deployed Advancion for projects we own and operate across seven 
countries, with 436 MW in operation, under construction or in advanced 
stage development. We also broke ground on a new gas-fired plant and 
LNG regasification facility in Panama, enabling us to play a leading role in 
delivering cleaner and lower-cost natural gas throughout Central America. 
We have deployed new technologies such as drones and robotics to improve 
safety and lower costs for our businesses, and we are continually seeking 
innovative applications of technologies to improve our performance. 

We continued to make progress on our strategic objectives throughout 
2016. Our asset sales program has now achieved $3.6 billion in total sale 
proceeds, allowing us to refocus our activities on select markets in which 
we have the greatest competitive advantage. In the process, we achieved 
our incremental $50 million cost savings and revenue enhancement target 
and we are on track to reach $350 million in annual savings by 2018. We 
brought on-line 2,976 MW of construction projects in 2016 to drive future 
growth. We also achieved our financial guidance, reduced our corporate 
debt and increased our dividend. 

Despite 2016 being a successful year overall, we did experience some 
headwinds. Several of our construction projects were delayed, most notably 
the Alto Maipo hydroelectric project in Chile, which required a restructuring 
of its financing and Power Purchase Agreement (PPA). We also had large 
impairments at DPL in Ohio and our Buffalo Gap wind projects in Texas, 
which reflect unsuccessful past investments.

The progress we did make in 2016 on our strategic objectives was reflected 
in our stock performance. We had a very positive year and generated total 
shareholder return of 26.3%, outperforming the S&P 500 (up 12.0%), the 
S&P Utilities Index (up 16.3%) and U.S. listed independent power producers 
(down 17.2%).

2016 RESULTS AND ACCOMPLISHMENTS
Turning to our specific results and accomplishments in 2016, we delivered 
on our financial guidance, continued to meet our commitments to our 
shareholders and extended our progress on our strategy. In terms of future 
growth in free cash flow and earnings, we expect 8%-10% growth in our 
financial metrics through 2020.

As a result of our actions in 2016, we generated Proportional Free Cash Flow 
of $1,417 million and Parent Free Cash Flow of $579 million. As expected, 
our Adjusted Earnings Per Share was below our 2015 results, primarily due 
to headwinds from foreign currency and commodity prices, as well as a 
continued decline in demand in Brazil. We were able to offset much of the 
impact, and our 2016 Adjusted EPS came in at $0.98. During the year, we 
also achieved many of our strategic objectives. In addition to the cost savings 
and completion of construction projects previously mentioned, we also: 

•  Announced or closed $500 million in proceeds from the sales or sell-

downs of eight businesses; 

•  Increased our quarterly dividend by 9.1%, to $0.12 per share, beginning in 

the first quarter of 2017; and

•  Advanced 3,389 MW of construction projects which are expected to 

come on-line through 2019.

SUCCESSFUL EXECUTION OF OUR STRATEGY
Since late 2011, we have successfully delivered on our strategic goals and during 
2016 we extended our progress. The actions we have taken since 2011, such 
as cutting our costs, de-levering and reducing our complexity through asset sales 
have put us in a strong position to execute on our strategic growth opportunities.

Reducing Complexity 
We have been rebalancing our business mix by exiting certain businesses 
to reduce risk and re-deploying our excess cash into debt repayment, share 
repurchases, dividends and growth projects with long-term, U.S. Dollar-
denominated contracts. Since 2011, we have raised $3.6 billion in equity 
proceeds from asset sales, decreasing the total number of countries where 
we have operations from 28 to 17. 

Leveraging Our Platforms for Long-Term Growth 
We are focusing our growth on platform expansions in markets where we 
already operate and have a competitive advantage to realize attractive 
risk-adjusted returns. Since 2011, we have brought on-line 7,932 MW of new 
projects, including 2,976 MW of platform expansion projects in 2016 alone.

We currently have 3,389 MW under construction, representing $6.4 billion 
in total capital expenditures, with the majority of AES’ $1.1 billion in equity 
already funded and expected to contribute a targeted return on our equity 
of approximately 14%. These projects under construction are the most 
significant driver of our near-term growth. 

Allocating Capital in a Disciplined Manner 
Our top priority is to maximize risk-adjusted returns to our shareholders, by 
taking a long-term perspective on investing our free cash flow.

Since 2011, we have generated substantial cash by executing on our 
strategy, which we allocated in line with our capital allocation framework: 

•  We used $2,263 million to prepay and refinance Parent debt;

•  We returned $2,402 million to shareholders through share repurchases 

and a quarterly dividend; and

•  We invested $1,336 million in our subsidiaries, largely for projects that 

are currently under construction.

We remain committed to strengthening our credit, which is largely driven 
by the successful completion of our construction program, cost reductions 
and de-levering. Accordingly, we continue to be confident that we can 
achieve investment grade stats by 2020.

CREATING LONG-TERM SHAREHOLDER VALUE
AES strives to create long-term shareholder value by providing safe and 
reliable electricity-related services in the markets we serve. We have a 
unique portfolio of businesses with significant presence in both mature 
and rapidly growing developing markets. This makes AES well positioned to 
deliver attractive long-term growth in cash flow, dividends and earnings. 

Underlying Strengths of Our Businesses
As a result of our proactive contracting and portfolio rebalancing initiatives, 
today, about 80% of our business is U.S. Dollar-based and about 83% is 
either contracted generation or regulated utilities. The average remaining life 
of the PPAs at our contracted businesses is six years, and when we complete 
our projects currently under construction, this will be extended to ten years. 
Long-term PPAs provide stability and predictability to our earnings and cash flow.

The majority of our businesses are low-cost, flexible and reliable electricity 
providers with strong locational advantages. Our knowledge of these 
markets and critical mass also puts us in a position to take advantage of 
growth opportunities or quickly respond to changing conditions.

Future Growth
Future growth across our markets will be heavily weighted towards less 
carbon-intensive natural gas, wind and solar generation. We will seek 
opportunities in these growth areas for projects with long-term, U.S. Dollar-
denominated contracts. The targeted projects will improve the quality of 
our cash flow and help us achieve our credit objectives, while reducing the 
carbon intensity of our portfolio.

With respect to renewables, we see an attractive business opportunity in 
light of several trends, such as: 

•  The dramatic drop in the cost of renewables that have made their energy 

production competitive; 

•  Growing demand for renewables – renewables have become the dominant 

type of new generation build across almost all of our markets; and

•  The availability of long-term PPAs for renewables, providing predictable, 

stable cash flows.

The intermittent nature of renewables does pose challenges for the grid. 
We believe AES’ ability to leverage renewables by integrating them with 
conventional generation and energy storage can meet these challenges and 
give us a strong competitive advantage. 

To that end, we recently agreed to acquire sPower, the largest independent 
solar developer in the United States. sPower brings 1.3 GW of installed 
capacity with an average remaining contract life of more than 20 years with 
very credit-worthy offtakers and a first class management and development 
team with a pipeline of more than 10 GW. We are very excited by the scale 
and capabilities from this acquisition as we look to expand our renewables 
portfolio across all our markets and integrate renewables with our extensive 
conventional generation fleet and world-leading energy storage platform.

SUSTAINABILITY

AES was named to the Dow Jones 
Sustainability Index (DJSI) for North America 
for the second year in a row by RobecoSAM.

AES was also named by Ethisphere as one 
of the World’s Most Ethical Companies for 
the second year in a row. 

DELIVERING SUSTAINABLE RESULTS
As a leading sustainable power company, our diverse mix of generation 
sources provides us the strength and flexibility to adapt to local and 
regional market needs, maximize plant efficiency and deliver reliable, 
affordable electricity. Our businesses do much more than just provide 
power. Improving lives and making a lasting difference in the communities 
in which our businesses operate has always been part of our values and 
mission. It is our responsibility to provide infrastructure solutions that 
support a sustainable social, economic and environmental future. Our 
sustainability activities focus on specific areas, or material aspects, within 
the context of five broad strategic initiatives: 

•  Financial Excellence

•  Operational Excellence

•  Environmental Performance

•  Stakeholder Engagement 

•  AES People

Our values are at the heart of our operations and these values set us apart 
from others in our industry. Every day, our people and businesses around 
the world are guided by the following core values:

•  Put Safety First

•  Act With Integrity

•  Honor Our Commitments

•  Strive for Excellence

•  Have Fun Through Work

Putting safety first for our people, contractors and communities, is our 
number one value. Unfortunately, 2016 was a very disappointing year for us 
as we experienced a major setback in our safety performance. Eight people 
from our generation and distribution businesses, as well as construction 
projects, died as a result of workplace injuries. We have a plan in place to 
take the information we have from each of these events and use it to help 
us deliver on our goal to create a workplace free of incidents.

In 2016, AES was named to the Dow Jones Sustainability Index (DJSI) for 
North America for the third year in a row by RobecoSAM. We were also 
named by Ethisphere as one of the World’s Most Ethical Companies for the 
third year in a row.

CONCLUSION
Our global platform, diverse portfolio mix by generation sources and 
technologies, and leading presence in many growing markets, make us well 
positioned to meet evolving customer needs and maximize shareholder value. 
We will continue to execute on our strategic objectives and seek to be the 
low-cost operator of assets in attractive markets, while exercising disciplined 
capital allocation that strengthens our credit and reduces overall volatility.

Thank you for your continued support.

(1)  We define adjusted earnings per share (“Adjusted EPS”), a non-GAAP measure, as diluted earnings per share from continuing operations excluding gains or losses of 
both consolidated entities and entities accounted for under the equity method due to (a) unrealized gains or losses related to derivative transactions, (b) unrealized 
foreign currency gains or losses, (c) gains or losses due to dispositions and acquisitions of business interests, (d) losses due to impairments, and (e) costs due to the early 
retirement of debt, adjusted for the same gains or losses excluded from consolidated entities. The GAAP measure most comparable to Adjusted EPS is diluted earnings 
per share from continuing operations. AES believes that Adjusted EPS better reflects the underlying business performance of the Company and is considered in the 
Company’s internal evaluation of financial performance. Factors in this determination include the variability due to unrealized gains or losses related to derivative trans-
actions, unrealized foreign currency gains or losses, losses due to impairments and strategic decisions to dispose or acquire business interests or retire debt, which affect 
results in a given period or periods. Adjusted EPS should not be construed as an alternative to diluted earnings per share from continuing operations, which is determined 
in accordance with GAAP.

(2)  Amount primarily relates to the loss on deconsolidation of UK Wind of $20 million, or $0.03 per share and losses associated with the sale of Sul of $10 million, or $0.02; 

partially offset by the gain on sale of DPLER of $22 million, or $0.03 per share.

(3)  Amount primarily relates to the gains on the sale of Armenia Mountain of $22 million, or $0.03 per share and from the sale of Solar Spain and Solar Italy of $7 million, or 

$0.01 per share.

projects of $78 million, or $0.11 per share.

(5)  Amount primarily relates to asset impairments at DPL of $859 million, or $1.30 per share; $159 million at Buffalo Gap II ($49 million, or $0.07 per share, net of NCI); and 

$77 million at Buffalo Gap I ($23 million, or $0.03 per share, net of NCI).

(6)  Amount primarily relates to the goodwill impairment at DPL of $317 million, or $0.46 per share, and asset impairments at Kilroot of $121 million ($119 million, or $0.17 

per share, net of NCI), at Buffalo Gap III of $116 million ($27 million, or $0.04 per share, net of NCI), and at U.K. Wind (Development Projects) of $38 million ($30 million, 
or $0.04 per share, net of NCI).

(7)  Amount primarily relates to the goodwill impairments at DPLER of $136 million, or $0.19 per share, and at Buffalo Gap I & II of $28 million, or $0.04 per share; and asset 
impairments at Ebute of $67 million ($64 million, or $0.09 per share, net of NCI), at Elsta of $41 million, or $0.06 per share; and the other-than-temporary impairments 
at Entek of $86 million, $0.12 per share and at Silver Ridge Power of $42 million, or $0.06 per share.

(8)  Amount primarily relates to the loss on early retirement of debt at the Parent Company of $19 million, or $0.03 per share.

(9)  Amount primarily relates to the loss on early retirement of debt at the Parent Company of $116 million, or $0.17 per share and at IPL of $22 million ($17 million, or $0.02

Angamos of $20 million ($14 million, or $0.02 per share, net of NCI) and at U.K. wind projects of $18 million, or $0.02 per share.

(11)  Amount primarily relates to the per share income tax benefit associated with asset impairment of $332 million, or $0.50 per share in the twelve months ended December 

31, 2016. 

(12)  Amount primarily relates to the per share income tax benefit associated with losses on extinguishment of debt of $55 million, or $0.08 per share in the twelve months 

ended December 31, 2015. 

(13)  Amount primarily relates to the per share income tax benefit associated with losses on extinguishment of debt of $90 million, or $0.12 per share and dispositions/acquisi-

tions of $67 million, or $0.09 per share in the twelve months ended December 31, 2014.

(14)  We define adjusted PTC, a non-GAAP measure, as pre-tax income from continuing operations attributable to AES excluding gains or losses of both consolidated entities 
and entities accounted for under the equity method due to (a) unrealized gains or losses related to derivative transactions, (b) unrealized foreign currency gains or losses, 
(c) gains or losses due to dispositions and acquisitions of business interests, (d) losses due to impairments, and (e) costs due to the early retirement of debt, adjusted for 
the same gains or losses excluded from consolidated entities. Adjusted PTC also includes net equity in earnings of affiliates on an after-tax basis. The GAAP measure 
most comparable to Adjusted PTC is income from continuing operations attributable to AES.  We believe that Adjusted PTC better reflects the underlying business 
performance of the Company and is considered in the Company’s internal evaluation of financial performance.  Factors in this determination include the variability due 
to unrealized gains or losses related to derivative transactions, unrealized foreign currency gains or losses, losses due to impairments and strategic decisions to dispose or 
acquire business interests or retire debt, which affect results in a given period or periods. Earnings before tax represents the business performance of the Company before 
the application of statutory income tax rates and tax adjustments, including the effects of tax planning, corresponding to the various jurisdictions in which the Company 
operates. Adjusted PTC should not be construed as an alternative to income from continuing operations attributable to AES, which is determined in accordance with 
GAAP.

(15)  Free cash flow (a non-GAAP financial measure) is defined as net cash from operating activities excluding capital expenditures related to service concession assets, less 

maintenance capital expenditures (including non-recoverable environmental capital expenditures), net of reinsurance proceeds from third parties. AES believes that free 
cash flow is a useful measure for evaluating our financial condition because it represents the amount of cash provided by operations less maintenance capital expendi-
tures as defined by our businesses, that may be available for investing or for repaying debt.  Free cash flow should not be construed as an alternative to net cash from 
operating activities, which is determined in accordance with GAAP.

(16)  AES is a holding company that derives its income and cash flows from the activities of its subsidiaries, some of which are not wholly-owned by the Company.  

Accordingly, the Company has presented certain financial metrics which are defined as Proportional (a non-GAAP financial measure) to account for the Company’s 
ownership interest.  Proportional metrics present the Company’s estimate of its share in the economics of the underlying metric.  The Company believes that the 
Proportional metrics are useful to investors because they exclude the economic share in the metric presented that is held by non-AES shareholders.  For example, net 
cash provided by operating activities (Operating Cash Flow) is a GAAP metric which presents the Company’s cash flow from operations on a consolidated basis, including 
operating cash flow allocable to noncontrolling interests.  Proportional Operating Cash Flow removes the share of operating cash flow allocable to noncontrolling 
interests and therefore may act as an aid in the valuation of the Company.  Proportional metrics are reconciled to the nearest GAAP measure.  Certain assumptions have 
been made to estimate our proportional financial measures.   These assumptions include:  (i) the Company’s economic interest has been calculated based on a blended 
rate for each consolidated business when such business represents multiple legal entities; (ii)  the Company’s economic interest may differ from the percentage implied 
by the recorded net income or loss attributable to noncontrolling interests or dividends paid during a given period; (iii) the Company’s economic interest for entities 
accounted for using the hypothetical liquidation at book value method is 100%; (iv) individual operating performance of the Company’s equity method investments is 
not reflected; and (v) inter-segment transactions are included as applicable for the metric presented.

(17)  The proportional adjustment factor, proportional maintenance capital expenditures (net of reinsurance proceeds) and proportional non-recoverable environmental 

capital expenditures are calculated by multiplying the percentage owned by noncontrolling interests for each entity by its corresponding consolidated cash flow metric 
and are totaled to the resulting figures. For example, Parent Company A owns 20% of Subsidiary Company B, a consolidated subsidiary. Thus, Subsidiary Company B 
has an 80% noncontrolling interest. Assuming a consolidated net cash flow from operating activities of $100 from Subsidiary B, the proportional adjustment factor for 
Subsidiary B would equal $80 (or $100 x 80%). The Company calculates the proportional adjustment factor for each consolidated business in this manner and then sums 
these amounts to determine the total proportional adjustment factor used in the reconciliation. The proportional adjustment factor may differ from the proportion 
of income attributable to noncontrolling interests as a result of (a) non-cash items which impact income but not cash and (b) AES’ ownership interest in the subsidiary 
where such items occur.

(18)  Service concession asset expenditures excluded from free cash flow and proportional free cash flow non-GAAP metrics. The Company adopted service concession 

accounting effective January 1, 2015.

(19)  Excludes IPL’s proportional recoverable environmental capital expenditures of $132 million, $205 million and $163 million for the years ended December 31, 2016, 2015 

and 2014, respectively.

(20)  Includes proportional adjustment amount for service concession asset expenditures of $15 million and $84 million for the years ended December 31, 2016 and 2015, 

respectively. The Company adopted service concession accounting effective January 1, 2015.

Legal Proceedings.

Executive Summary 

Incorporated in 1981, AES is a diversified power generation and utility company, providing affordable, 

sustainable energy through our diverse portfolio of thermal and renewable generation facilities as well as 
distribution businesses.  Our vision is to be the world's leading sustainable power company by leveraging our 
unique electricity platforms and the knowledge of our people to provide the energy and infrastructure solutions our 
customers truly need. Our people share a passion to help meet the world's current and increasing energy needs, 
while providing communities and countries the opportunity for economic growth due to the availability of reliable, 
affordable electric power.

Future growth across our company will be heavily weighted towards less carbon-intensive wind, solar and gas 

generation. Growth in renewables not only provides an opportunity for direct investments in wind and solar 
generation, but also presents significant potential for energy storage. We are a leader in lithium ion, battery-based 
energy storage, with more than 400 MW in operation, under construction or in advanced development across seven 
countries. We believe lithium ion-based energy storage will play a critical role in an increasingly renewables-based 
generation mix. With our technological experience, presence in key markets and channel sales partnerships, we are 
positioned to capitalize on this rapidly growing market.

Additionally, we have been expanding our LNG infrastructure in Central America, where we are helping to 
displace oil-fired generation in favor of a cheaper and cleaner alternative. In the United States, at IPL, we recently 
completed a multi-year rate-base investment in environmental upgrades to our coal plants and are in the process of 
re-powering several units from coal to gas.

Investments in subsidiaries excludes $2.2 billion investment in DPL.

7

Segments

We are organized into six market-oriented strategic business units ("SBUs"): US (United States), Andes 

(Chile, Colombia, and Argentina), Brazil, MCAC (Mexico, Central America and the Caribbean), Europe, and Asia 
— which are led by our SBU Presidents. Within our six SBUs, we have two lines of business. The first business line 
is generation, where we own and/or operate power plants to generate and sell power to customers, such as utilities, 
industrial users, and other intermediaries. The second business line is utilities, where we own and/or operate 
utilities to generate or purchase, distribute, transmit and sell electricity to end-user customers in the residential, 
commercial, industrial and governmental sectors within a defined service area. In certain circumstances, our utilities 
also generate and sell electricity on the wholesale market.

The Company measures the operating performance of its SBUs using Adjusted PTC and Proportional Free 
Cash Flow, both of which are non-GAAP measures. The Adjusted PTC and Proportional Free Cash Flow by SBU 
for the year ended December 31, 2016 are shown below. The percentages for Adjusted PTC and Proportional Free 
Cash Flow are the contribution by each SBU to the gross metric, i.e., the total Adjusted PTC by SBU, before 
deductions for Corporate. See Item 7.—Management's Discussion and Analysis SBU Performance Analysis of this 
Form 10-K for reconciliation and definitions of Adjusted PTC and Proportional Free Cash Flow.

The following summarizes our businesses within our six SBUs.

Overview 
Generation

We currently own and/or operate a generation portfolio of 30,379 MW, excluding the generation capabilities of 

our integrated utilities. Our generation fleet is diversified by fuel type. See discussion below under Fuel Costs.

Performance drivers of our generation businesses include types of electricity sales agreements, plant 
reliability and flexibility, fuel costs, seasonality, weather variations and economic activity, fixed-cost management, 
and competition.

Electricity Sales Contracts — Our generation businesses sell electricity under medium- or long-term contracts 

("contract sales") or under short-term agreements in competitive markets ("short-term sales").

Contract Sales — Most of our generation fleet sells electricity under contracts. Our medium-term contract 

sales have a term of 2 to 5 years, while our long-term contracts have a term of more than 5 years. Across our 
portfolio, the average remaining contract term is 6 years.

In contract sales, our generation businesses recover variable costs including fuel and variable O&M costs, 
either through direct or indexation-based contractual pass-throughs or tolling arrangements. When the contract 
does not include a fuel pass-through, we typically hedge fuel costs or enter into fuel supply agreements for a similar 
contract period (see discussion under the Fuel Costs section below). These contracts are intended to reduce 
exposure to the volatility of fuel prices and electricity prices by linking the business's revenues and costs. These 
contracts also help us to fund a significant portion of the total capital cost of the project through long-term non-
recourse project-level financing.

Capacity Payments and Contract Sales — Most of our contract sales include a capacity payment that covers 
projected fixed costs of the plant, including fixed O&M expenses and a return on capital invested. In addition, most 
of our contracts require that the majority of the capacity payment be denominated in the currency matching our 
fixed costs. We generally structure our business to eliminate or reduce foreign exchange risk by matching the 
currency of revenue and expenses, including fixed costs and debt. Our project debt may consist of both fixed and 
floating rate debt for which we typically hedge a significant portion of our exposure. Some of our contracted 
businesses also receive a regulated market-based capacity payment, which is discussed in more detail in the 
Capacity Payments and Short-Term Sales section below.

Thus, these contracts, or other related commercial arrangements, significantly mitigate our exposure to 
changes in power and fuel prices, currency fluctuations and changes in interest rates. In addition, these contracts 
generally provide for a recovery of our fixed operating expenses and a return on our investment, as long as we 
operate the plant to the reliability and efficiency standards required in the contract.

Short-Term Sales — Our other generation businesses sell power and ancillary services under short-term 

contracts with an average term of less than 2 years, including spot sales, directly in the short-term market, or, in 
some cases, at regulated prices. The short-term markets are typically administered by a system operator to 
coordinate dispatch. Short-term markets generally operate on merit order dispatch, where the least expensive 
generation facilities, based upon variable cost or bid price, are dispatched first and the most expensive facilities are 
dispatched last. The short-term price is typically set at the marginal cost of energy or bid price (the cost of the last 
plant required to meet system demand). As a result, the cash flows and earnings associated with these businesses 
are more sensitive to fluctuations in the market price for electricity. In addition, many of these wholesale markets 
include markets for ancillary services to support the reliable operation of the transmission system. Across our 
portfolio, we provide a wide array of ancillary services, including voltage support, frequency regulation and spinning 
reserves. 

In certain markets, such as Argentina and Kazakhstan, a regulator establishes the prices for electricity and 

fuel and adjusts them periodically for inflation, changes in fuel prices and other factors. In these cases, our 
businesses are particularly sensitive to changes in regulation.

Capacity Payments — Many of the markets in which we operate include regulated capacity markets. These 

capacity markets are intended to provide additional revenue based upon availability without reliance on the energy 
margin from the merit order dispatch. Capacity markets are typically priced based on the cost of a new entrant and 
the system capacity relative to the desired level of reserve margin (generation available in excess of peak demand). 
Our generating facilities selling in the short-term markets typically receive capacity payments based on their 
availability in the market. Our most significant capacity revenues are earned by our generation capacity in Ohio and 
Northern Ireland.

12

Plant Reliability and Flexibility — Our contract and short-term sales provide incentives to our generation plants 

to optimally manage availability, operating efficiency and flexibility. Capacity payments under contract sales are 
frequently tied to meeting minimum standards. In short-term sales, our plants must be reliable and flexible to 
capture peak market prices and to maximize market-based revenues. In addition, our flexibility allows us to capture 
ancillary service revenue while meeting local market needs.

Fuel Costs — For our thermal generation plants, fuel is a significant component of our total cost of generation. 

For contract sales, we often enter into fuel supply agreements to match the contract period, or we may hedge our 
fuel costs. Some of our contracts have periodic adjustments for changes in fuel cost indices. In those cases, we 
have fuel supply agreements with shorter terms to match those adjustments. For certain projects, we have tolling 
arrangements where the power offtaker is responsible for the supply and cost of fuel to our plants.

In short-term sales, we sell power at market prices that are generally reflective of the market cost of fuel at the 

time, and thus procure fuel supply on a short-term basis, generally designed to match up with our market sales 
profile. Since fuel price is often the primary determinant for power prices, the economics of projects with short-term 
sales are often subject to volatility of relative fuel prices. For further information regarding commodity price risk 
please see Item 7A.—Quantitative and Qualitative Disclosures about Market Risk in this Form 10-K.

34% of the capacity of our generation fleet is coal-fired. In the U.S., most of our plants are supplied from 
domestic coal. At our non-U.S. generation plants, and at our plant in Hawaii, we source coal internationally. Across 
our fleet, we utilize our global sourcing program to maximize the purchasing power of our fuel procurement.

33% of the capacity of our generation plants are fueled by natural gas. Generally, we use gas from local 
suppliers in each market. A few exceptions to this are AES Gener in Chile, where we purchase imported gas from 
third parties, and our plants in the Dominican Republic, where we import LNG to utilize in the local market.

27% of the capacity of our generation plants are fueled by renewables, including hydro, wind and energy 

storage, which do not have significant fuel costs.

6% of the capacity of our generation fleet utilizes oil, diesel and petroleum coke ("pet coke") for fuel. Oil and 
diesel are sourced locally at prices linked to international markets, while pet coke is largely sourced from Mexico 
and the U.S. 

Renewable Generation Facilities — We currently own and operate 8,228 MW (4,293 proportional MW) of 

renewable generation, including hydro, wind, energy storage, solar, biomass and landfill gas.

Seasonality, Weather Variations and Economic Activity — Our generation businesses are affected by seasonal 
weather patterns throughout the year and, therefore, operating margin is not generated evenly by month during the 
year. Additionally, weather variations, including temperature, solar and wind resources, and hydrological conditions, 
may also have an impact on generation output at our renewable generation facilities. In competitive markets for 
power, local economic activity can also have an impact on power demand and short-term prices for power.

Fixed-Cost Management — In our businesses with long-term contracts, the majority of the fixed O&M costs 
are recovered through the capacity payment. However, for all generation businesses, managing fixed costs and 
reducing them over time is a driver of business performance.

Competition — For our businesses with medium- or long-term contracts, there is limited competition during the 

term of the contract. For short-term sales, plant dispatch and the price of electricity are determined by market 
competition and local dispatch and reliability rules.

Utilities

AES' seven utility businesses distribute power to 9.4 million people in three countries. AES' two utilities in the 

U.S. also include generation capacity totaling 6,314 MW. The utility businesses have a variety of structures, ranging 
from integrated utility to pure transmission and distribution businesses.

In general, our utilities sell electricity directly to end-users, such as homes and businesses, and bill customers 

directly. Key performance drivers for utilities include the regulated rate of return and tariff, seasonality, weather 
variations, economic activity, reliability of service and competition. Revenue from utilities is classified as regulated in 
the Consolidated Statements of Operations.

Regulated Rate of Return and Tariff — In exchange for the exclusive right to sell or distribute electricity in a 

franchise area, our utility businesses are subject to government regulation. This regulation sets the prices ("tariffs") 
that our utilities are allowed to charge retail customers for electricity and establishes service standards that we are 
required to meet.

13

Our utilities are generally permitted to earn a regulated rate of return on assets, determined by the regulator 
based on the utility's allowed regulatory asset base, capital structure and cost of capital. The asset base on which 
the utility is permitted a return is determined by the regulator and is based on the amount of assets that are 
considered used and useful in serving customers. Both the allowed return and the asset base are important 
components of the utility's earning power. The allowed rate of return and operating expenses deemed reasonable 
by the regulator are recovered through the regulated tariff that the utility charges to its customers.

The tariff may be reviewed and reset by the regulator from time to time depending on local regulations, or the 

utility may seek a change in its tariffs. The tariff is generally based upon a certain usage level and may include a 
pass-through to the customer of costs that are not controlled by the utility, such as the costs of fuel (in the case of 
integrated utilities) and/or the costs of purchased energy. In addition to fuel and purchased energy, other types of 
costs may be passed through to customers via an existing mechanism, such as certain environmental expenditures 
that are covered under an environmental tracker at our utility in Indiana, IPL. Components of the tariff that are 
directly passed through to the customer are usually adjusted through a summary regulatory process or an existing 
formula-based mechanism. In some regulatory regimes, customers with demand above an established level are 
unregulated and can choose to contract with other retail energy suppliers directly and pay wheeling and other non-
bypassable fees, which are fees to the distribution company for use of its distribution system.

The regulated tariff generally recognizes that our utility businesses should recover certain operating and fixed 

costs, as well as manage uncollectible amounts, quality of service and non-technical losses. Utilities, therefore, 
need to manage costs to the levels reflected in the tariff, or risk non-recovery of costs or diminished returns.

Seasonality, Weather Variations and Economic Activity — Our utility businesses are affected by seasonal 

weather patterns throughout the year and, therefore, the operating revenues and associated operating expenses 
are not generated evenly by month during the year. Additionally, weather variations may also have an impact based 
on the number of customers, temperature variances from normal conditions and customers' historic usage levels 
and patterns. The retail kWh sales, after adjustments for weather variations, are affected by changes in local 
economic activity, energy efficiency and distributed generation initiatives, as well as the number of retail customers.

Reliability of Service — Our utility businesses must meet certain reliability standards, such as duration and 

frequency of outages. Those standards may be specific with incentives or penalties for performance against these 
standards. In other cases, the standards are implicit and the utility must operate to meet customer expectations.

Competition — Our integrated utilities, IPL and DP&L, operate as the sole distributor of electricity within their 

respective jurisdictions. Our businesses own and operate all of the businesses and facilities necessary to generate, 
transmit and distribute electricity. Competition in the regulated electric business is primarily from the on-site 
generation for industrial customers; however, in Ohio, customers in our service territory have the ability to switch to 
alternative suppliers for their generation service. Our integrated utilities, particularly DP&L, are exposed to the 
volatility in wholesale prices to the extent our generating capacity exceeds the native load served under the 
regulated tariff and short-term contracts. See the full discussion under the US SBU.

At our pure transmission and distribution businesses, such as those in Brazil and El Salvador, we face 
relatively limited competition due to significant barriers to entry. At many of these businesses, large customers, as 
defined by the relevant regulator, have the option to both leave and return to regulated service.

Development and Construction 

We develop and construct new generation facilities. For our utility businesses, new plants may be built in 

response to customer needs or to comply with regulatory developments and are developed subject to regulatory 
approval that permits recovery of our capital cost and a return on our investment. For our generation businesses, 
our priority for development is platform expansion opportunities, where we can add on to our existing facilities in our 
key platform markets where we have a competitive advantage. We make the decision to invest in new projects by 
evaluating the project returns and financial profile against a fair risk-adjusted return for the investment and against 
alternative uses of capital, including corporate debt repayment and share buybacks.

In some cases, we enter into long-term contracts for output from new facilities prior to commencing 

construction. To limit required equity contributions from The AES Corporation, we also seek non-recourse project 
debt financing and other sources of capital, including partners where it is commercially attractive. For construction, 
we typically contract with a third party to manage construction, although our construction management team 
supervises the construction work and tracks progress against the project's budget and the required safety, efficiency 
and productivity standards.

U.S. Businesses

U.S. Utilities

IPALCO

Business Description — IPALCO owns all of the outstanding common stock of IPL. IPL is engaged primarily in 
generating, transmitting, distributing and selling electric energy to approximately 490,000 retail customers in the city 
of Indianapolis and neighboring areas within the state of Indiana. IPL has an exclusive right to provide electric 
service to those customers. IPL's service area covers about 528 square miles with an estimated population of 
approximately 939,000. IPL owns and operates four generating stations. IPL’s largest generating station, 
Petersburg, is coal-fired. The second largest station, Harding Street, has converted its coal-fired units to natural gas 
and uses natural gas and fuel oil to power combustion turbines. The third, Eagle Valley, retired its coal-fired units in 
April 2016 and their CCGT is expected to be completed in the first half of 2018. The fourth station, Georgetown, is a 
small peaking station that uses natural gas to power combustion turbines. As of December 31, 2016, IPL's net 
electric generation capacity for winter is 2,993 MW and net summer capacity is 2,878 MW. 

Market Structure — IPL is one of many transmission system owner members in the MISO. MISO is a RTO, 
which maintains functional control over the combined transmission systems of its members and manages one of the 
largest energy and ancillary services markets in the U.S. IPL offers the available electricity production of each of its 
generation assets into the MISO day-ahead and real-time markets. MISO operates on a merit order dispatch, 
considering transmission constraints and other reliability issues to meet the total demand in the MISO region. 

Regulatory Framework - Retail Ratemaking — In addition to the regulations referred to below in Other 
Regulatory Matters, IPL is subject to regulation by the IURC with respect to IPL's services and facilities; retail rates 
and charges; the issuance of long-term securities; and certain other matters. The regulatory power of the IURC over 
IPL's business is both comprehensive and typical of the traditional form of regulation generally imposed by state 
public utility commissions. IPL's tariff rates for electric service to retail customers consist of basic rates and charges, 

16

which are set and approved by the IURC after public hearings. The IURC gives consideration to all allowable costs 
for ratemaking purposes including a fair return on the fair value of the utility property used and useful in providing 
service to customers. In addition, IPL's rates include various adjustment mechanisms including, but not limited to: (i) 
a rider to reflect changes in fuel and purchased power costs to meet IPL's retail load requirements, referred to as 
the FAC, and (ii) a rider for the timely recovery of costs incurred to comply with environmental laws and regulations 
referred to as the Environmental Compliance Cost Recovery Adjustment. These components function somewhat 
independently of one another, but the overall structure of IPL's rates and charges would be subject to review at the 
time of any review of IPL's basic rates and charges. 

In March 2016, the IURC issued an order authorizing IPL to increase its basic rates and charges by 
approximately $31 million annually. On December 22, 2016, IPL filed a petition with the IURC for authority to 
increase its basic rates and charges, primarily to recover the cost of the new Eagle Valley CCGT. The Eagle Valley 
CCGT was previously expected to be completed in the first half of 2017, but is now expected to be completed in the 
first half of 2018. To address this change, on February 24, 2017, IPL filed a motion to withdraw the case without 
prejudice or alternatively amend the petition at a later date. No assurances can be given as to the timing or 
outcome of this proceeding.

Environmental Regulation — For information on compliance with environmental regulations see Item 1.—

United States Environmental and Land-Use Legislation and Regulations.

Replacement Generation — IPL has several generating units that have been recently retired or refueled. 

These units were primarily coal-fired and represented 472 MW of net capacity in total. To replace this generation, 
IPL has approval to build a 644 to 685 MW CCGT at its Eagle Valley Station site in Indiana and refuel its Harding 
Street Station Units 5 and 6 from coal to natural gas (approximately 100 MW net capacity each) with a total budget 
of $649 million. The current estimated cost of these projects is $632 million. IPL was granted authority to accrue 
post in-service allowance for debt and equity funds used during construction, and to defer the recognition of 
depreciation expense of the CCGT and refueling project. These costs to build and operate the CCGT and the 
refueling project, other than fuel costs, will not be recoverable by IPL through rates until the conclusion of a base 
rate case proceeding with the IURC after the assets have been placed in service. The CCGT is expected to be 
completed in the first half of 2018, and the refueling project was completed in December 2015.

In July 2015 IPL received approval from the IURC for a CPN to refuel the Harding Street Station Unit 7 from 
coal to natural gas (about 410 MW net capacity). The Harding Street Station Unit 7 conversion was completed in 
the second quarter of 2016.

Key Financial Drivers — IPL's financial results are driven primarily by retail demand, weather, energy 
efficiency and wholesale prices. In addition, IPL's financial results are likely to be driven by many factors including 
but not limited to:

• 
• 
• 

rate case outcomes
the timely recovery of capital expenditures through base rate growth
the passage of new legislation or implementation of regulations

Construction and Development — IPL's construction program is composed of capital expenditures necessary 

for prudent utility operations and compliance with environmental laws and regulations, along with discretionary 
investments designed to replace aging equipment or improve overall performance. Refer to the section above for a 
description of our major construction projects.

DPL 

Business Description — DPL is an energy holding company whose principal subsidiaries include DP&L and 

AES Ohio Generation, LLC. 

DP&L generates, transmits, distributes and sells electricity to approximately 519,000 customers in a 6,000 

square mile area of West Central Ohio. DP&L, solely or through jointly owned facilities, owns 2,510 MW of 
generation capacity and numerous transmission facilities. 

AES Ohio Generation, LLC owns peaking generation units representing 556 MW located in Ohio and Indiana. 

On January 1, 2016, DPL closed on the sale of DPLER to Interstate Gas Supply, Inc. DPLER, a competitive 

retail marketer, sold retail electricity to more than 124,000 retail customers in Ohio and Illinois while owned by DPL. 
Approximately 110,000 of those customers were also distribution customers of DP&L in Ohio. 

Market Structure — Since January 2001, electric customers within Ohio have been permitted to choose to 
purchase power under a contract with a CRES Provider or to continue to purchase power from their local utility 

17

under SSO rates established by the tariff. DP&L and other Ohio utilities continue to have the exclusive right to 
provide delivery service in their state certified territories, and DP&L has the obligation to provide retail generation 
service to customers that did not choose an alternative supplier. Beginning in 2014, a portion of the SSO generation 
supply was no longer supplied by DP&L, but was provided by third parties through a competitive bid process. A total 
of 10%, 60% and 100% of the SSO load was sourced through competitive bid in 2014, 2015 and 2016, respectively. 
The PUCO maintains jurisdiction over DP&L's delivery of electricity, SSO and other retail electric services. The 
PUCO has issued extensive rules on how and when a customer can switch generation suppliers, how the local 
utility will interact with CRES Providers and customers, including for billing and collection purposes, and which 
elements of a utility's rates are "bypassable" (i.e., avoided by a customer that elects a CRES Provider) and which 
elements are "non-bypassable" (i.e., charged to all customers receiving a distribution service irrespective of what 
entity provides the retail generation service). 

DP&L is a member of PJM. The PJM RTO operates the transmission systems owned by utilities operating in 
all or parts of Pennsylvania, New Jersey, Maryland, Delaware, D.C., Virginia, Ohio, West Virginia, Kentucky, North 
Carolina, Tennessee, Indiana and Illinois. PJM has an integrated planning process to identify potential needs for 
additional transmission to be built to avoid future reliability problems. PJM also runs the day-ahead and real-time 
energy markets, ancillary services market and forward capacity market for its members. 

As a member of PJM, DP&L is also subject to charges and costs associated with PJM operations as approved 
by the FERC. Prior to 2015, the RPM was PJM's capacity construct. In 2015, PJM implemented a new CP program, 
replacing the RPM model. The CP program offers the potential for higher capacity revenues, combined with 
substantially increased penalties for non-performance or under-performance during certain periods identified as 
"capacity performance hours." This linkage between non- or under-performance during specific hours means that a 
generation unit that is generally performing well on an annual basis, may incur substantial penalties if it happens to 
be unavailable for service during some capacity performance hours. Similarly, a generation unit that is generally 
performing poorly on an annual basis may avoid such penalties if its outages happen to occur only during hours that 
are not capacity performance hours. An annual “stop-loss” provision exists that limits the size of penalties to 150% 
of the net cost of new entry, which is a value computed by PJM. This level is likely to be larger than the capacity 
price established under the CP program, so that there is potential that participation in the CP program could result 
in capacity penalties that exceed capacity revenues. The purpose of the RPM and CP Program is to enable PJM to 
obtain sufficient resources to reliably meet the needs of electric customers within the PJM footprint. PJM conducts 
an auction to establish the price by zone. 

The PJM CP auctions are held three years in advance for a period covering 12 months starting from June 1. 

Auctions for the period covering June 1, 2020 through May 30, 2021 are expected to take place in May 2017. 
Future auction results are dependent upon various factors including the demand and supply situation, capacity 
additions and retirements and any changes in the current auction rules related to bidding for demand response and 
energy efficiency resources in the capacity auctions. For DPL-owned generation, applicable capacity prices through 
the auction year 2019/20 are as follows: 

Auction Year (June 01-May 31)
Capacity Clearing Price ($/MW-Day)

2019/20

The above tables reflect the capacity prices after the transitional auctions discussed earlier. Substantially all of 

DP&L's capacity cleared in the CP auction. The results of these auctions could have a significant effect on DP&L's 
revenues in the future.

Regulatory Framework - Retail Regulation and Rate Structure — DP&L is subject to regulation by the PUCO, 

for its distribution services and facilities, retail rates and charges, reliability of service, compliance with renewable 
energy portfolio, energy efficiency program requirements and certain other matters. DP&L's rates for electric service 
to retail customers consist of basic rates and charges that are set and approved by the PUCO after public hearings. 
In addition, DP&L's rates include various adjustment mechanisms including, but not limited to, the timely recovery of 
costs incurred to comply with alternative energy, renewables, energy efficiency, and economic development costs. 
These components function independently of one another, but the overall structure of DP&L's retail rates and 
charges are subject to the rules and regulations established by the PUCO. 

 Since Ohio is deregulated, and allows customers to choose retail generation providers, DP&L is required to 

provide retail generation service at SSO rates to any customer that has not signed a contract with a CRES provider. 

18

SSO rates are subject to rules and regulations of the PUCO and are established based on DP&L's most recently 
approved ESP. DP&L's distribution rates are regulated by the PUCO and are established through a traditional cost-
based rate-setting process. DP&L is permitted to recover its costs of providing distribution service as well as earn a 
regulated rate of return on assets, determined by the regulator, based on the utility's allowed regulated asset base, 
capital structure and cost of capital. DP&L's wholesale transmission rates are regulated by the FERC.

Although it had been in effect since January 2014, on June 20, 2016, the Supreme Court of Ohio ("Court") 

issued an opinion in the appeal of DP&L’s ESP (ESP 2) that had been approved by the PUCO for the years 
2014-2016 and which, among other matters, permitted DP&L to collect a non-bypassable Service Stability Rider 
equal to $110 million per year from 2014-2016 and required DP&L to conduct competitive bid auctions to procure 
generation supply for SSO service. DP&L's own generation was phased-out of supplying SSO service over the 
three year period and beginning January 1, 2016 DP&L's SSO was 100% sourced through the competitive bid. In 
the opinion, the Court stated that the PUCO’s approval of ESP 2 was reversed. In view of that reversal, DP&L filed 
a motion to withdraw ESP 2 and implement rates consistent with those in effect prior to 2014 (ESP 1). Those rates 
will be in effect until rates consistent with DP&L’s pending February 22, 2016 ESP (ESP 3) filing are approved and 
effective. 

DP&L originally filed its ESP 3 seeking an effective date of January 1, 2017. On October 11, 2016, DP&L 
amended the application requesting to recover $145 million per year for seven years supporting the alternative 
described in the original filing, named the Distribution Modernization Rider. This plan establishes the terms and 
conditions for DP&L's SSO beginning June 1, 2017 to customers that do not choose a competitive retail electric 
supplier.  In its plan, DP&L recommends including renewable energy attributes as part of the product that is 
competitively bid, and seeks recovery of approximately $11 million of regulatory assets. The plan also proposes a 
new Distribution Investment Rider to allow DP&L to recover costs associated with future distribution equipment and 
infrastructure needs. Additionally, the plan establishes new riders set initially at zero, related to energy reductions 
from DP&L's energy efficiency programs, and certain environmental liabilities the Company may incur. 

On January 30, 2017 DP&L, in conjunction with nine intervening parties, filed a settlement in the ESP 3 case, 
which is subject to PUCO approval. DP&L and the intervening parties agreed to a six-year settlement that provides 
a framework for energy rates and defines components which include, but are not limited to, the following: 

•  The establishment of a five-year Distribution Modernization Rider designed to collect $90 million in revenue per 
year to pay debt obligations at DPL and DP&L and position DP&L to modernize and/or maintain its transmission 
and distribution infrastructure; 

•  The establishment of a Distribution Investment Rider for distribution investments, with one component designed 
to collect $35 million in revenue per year to enable the implementation of smart grid and advanced metering, 
ending after the fifth year of the term of the ESP, 

•  A commitment by the Company to separate DP&L’s generation assets from its transmission and distribution 

assets (if approved by FERC); 

•  A commitments to commence the sale process of our ownership interests in the Zimmer, Miami Fort and 

Conesville coal-fired generation plants and; 

•  A commitment to develop or procure wind and/or solar energy projects in Ohio, 
•  Restrictions on DPL making dividend or tax sharing payments, various other riders, and competitive retail market 

enhancements.

A hearing on the stipulation has been scheduled for March 2017. A final decision by the PUCO is expected at 
the end of Q2 or early Q3 2017. If the PUCO agrees to the proposed settlement, the average residential customer 
in the DP&L service territory, using 1,000 kWh on DP&L's Standard Service Offer, can expect a monthly bill 
increase of $2.39. There can be no assurance that the ESP 3 stipulation will be approved as filed or on a timely 
basis, and if the final ESP provides for terms that are more adverse than those submitted in DP&L's stipulation, our 
results of operations, financial condition and cash flows could be materially impacted.

On November 30, 2015 DP&L filed an application to increase its distribution rate case using a 12-month test 

year of June 1, 2015 to May 31, 2016 to measure revenue and expenses and a date certain of September 30, 2015 
to measure its asset base. The Company is seeking an increase to distribution revenues of $66 million per year. 
The Company has asked for recovery of certain regulatory assets as well as two new riders that would allow the 
Company to recover certain costs on an ongoing basis. It has proposed a modified straight-fixed variable rate 
design in an effort to decouple distribution revenues from electric sales. If approved as filed the rates are expected 
to have a total bill impact of approximately 4% on a typical residential customer.

Environmental Regulation — In relation to MATS, DPL does not expect to incur material capital expenditures 
to ensure compliance. For more information see Item 1.—United States Environmental and Land-Use Legislation 

19

and Regulations.

Key Financial Drivers — DPL financial results are driven by retail demand, weather, energy efficiency and 

wholesale prices on financial results. In addition, DPL financial results are likely to be driven by many factors 
including, but not limited to:

•  PJM capacity prices

•  Outcome of DP&L's pending ESP 3 case, including the amount of non-bypassable revenue
•  Outcome of DP&L's pending distribution rate case

•  Operational performance of generation facilities
•  Recovery in the power market, particularly as it relates to an expansion in dark spreads

•  Sale or transfer to a DPL affiliate of DP&L generation assets
•  DPL's ability to reduce its cost structure 

Construction and Development — Planned construction additions primarily relate to new investments in and 
upgrades to DP&L's power plant equipment and transmission and distribution system. Capital projects are subject 
to continuing review and are revised in light of changes in financial and economic conditions, load forecasts, 
legislative and regulatory developments and changing environmental standards, among other factors. 

DPL is projecting to spend an estimated $414 million in capital projects for the period 2017 through 2019 with 

65% attributable to Transmission and Distribution. DPL's ability to complete capital projects and the reliability of 
future service will be affected by its financial condition, the availability of internal funds and the reasonable cost of 
external funds. We expect to finance these construction additions with a combination of cash on hand, short-term 
financing, long-term debt and cash flows from operations.

U.S. Generation 

Business Description — In the U.S., we own a diversified generation portfolio in terms of geography, 
technology and fuel source. The principal markets and locations where we are engaged in the generation and 
supply of electricity (energy and capacity) are the Western Electric Coordinating Council, PJM, Southwest Power 
Pool Electric Energy Network and Hawaii. AES Southland, in the Western Electric Coordinating Council, is our most 
significant generating business. 

Many of our U.S. generation plants provide baseload operations and are required to maintain a guaranteed 

level of availability. Any change in availability has a direct impact on financial performance. The plants are generally 
eligible for availability bonuses on an annual basis if they meet certain requirements. In addition to plant availability, 
fuel cost is a key business driver for some of our facilities. 

AES Southland

Business Description — In terms of aggregate installed capacity, AES Southland is one of the largest 

generation operators in California, with an installed gross capacity of 3,941 MW, accounting for approximately 5% of 
the state's installed capacity and 17% of the peak demand of Southern California Edison. The three coastal power 
plants comprising AES Southland are in areas that are critical for local reliability and play an important role in 
integrating the increasing amounts of renewable generation resources in California. 

Market Structure — All of AES Southland's capacity is contracted through a long-term agreement (the “Tolling 
Agreement”), which expires in May 31, 2018. A Resource Adequacy agreement has been executed that covers the 
period from June 1, 2018 through 2020, but it is still subject to approval from the California Public Utilities 
Commission. Under the current Tolling Agreement, AES Southland's largest revenue driver is unit availability, as 
approximately 98% of its revenue comes from availability-related payments. Historically, AES Southland has 
generally met or exceeded its contractual availability requirements under the Tolling Agreement and may capture 
bonuses for exceeding availability requirements in peak periods.

Under the Tolling Agreement, the offtaker provides gas to the three facilities thus AES Southland is not 
exposed to significant fuel price risk. If the units operate better than the guaranteed efficiency, AES Southland gets 
credit for the gas that is not consumed. Conversely, AES Southland is responsible for the cost of fuel in excess of 
what would have been consumed had the guaranteed efficiency been achieved. The business is also exposed to 
replacement power costs for a limited period if dispatched by the offtaker and not able to meet the required 
generation.

AES Southland delivers electricity into the California ISO's market through its Tolling Agreement counterparty.

Environmental Regulation — For a discussion of environmental regulatory matters affecting U.S. Generation, 

see Item 1.—United States Environmental and Land-Use Legislation and Regulations.

Re-powering — In October 2014, AES Southland was awarded 20-year contracts by SCE to provide 1,284 

MW of combined cycle gas-fired generation and 100 MW of interconnected battery-based energy storage. In 
addition to replacing older gas-fired plants with more efficient gas-fired capacity, SCE chose advanced energy 
storage as a cost effective way to ensure critical power system reliability. This new storage resource will provide 
operational flexibility, enabling the efficient dispatch of other generating plants, lowering cost and emissions and 
supporting the on-going addition of renewable power sources. 

This new capacity will be built at the Company's existing power plant sites in Huntington Beach and Alamitos 

Beach. For the gas-fired capacity, financing agreements are expected to be completed in mid-2017 with 
construction expected to begin shortly thereafter, and commercial operation scheduled for 2020. For the energy 
storage capacity, commercial operation is scheduled for 2021. 

AES is pursuing permits to build both the gas-fired and energy storage capacity and will complete the 

licensing process before financial close. The total cost for these projects is expected to be approximately $1.9 
billion, which will be funded with a combination of non-recourse debt and AES equity.

Key Financial Drivers — AES Southland's contractual availability is the single most important driver of 

operations. Its units are generally required to achieve at least 86% availability in each contract year. AES Southland 
has historically met or exceeded its contractual availability.

Additional U.S. Generation Businesses

Business Description — Additional businesses include thermal, wind, and solar generating facilities, of which 

AES Hawaii, our U.S. wind generation businesses and distributed solar are the most significant. 

•  AES Hawaii — AES Hawaii receives a fuel payment from its offtaker under a PPA expiring in 2022, which is 

based on a fixed rate indexed to the Gross National Product - Implicit Price Deflator. Since the fuel payment is 
not directly linked to market prices for fuel, the risk arising from fluctuations in market prices for coal is borne by 
AES Hawaii. 

To mitigate the risk from such fluctuations, AES Hawaii has entered into fixed-price coal purchase commitments 
that end in December 2018; the business could be subject to variability in coal pricing beginning in January 
2019. To mitigate fuel risk beyond December 2018, AES Hawaii plans to seek additional fuel purchase 
commitments on favorable terms. However, if market prices rise and AES Hawaii is unable to procure coal 
supply on favorable terms, the financial performance of AES Hawaii could be materially and adversely affected.

•  U.S. Wind — AES has 736 MW of wind capacity in the U.S., located in California, Texas and West Virginia. 
Typically, these facilities sell under long-term PPAs. AES financed most of these projects with tax equity 
structures. The tax equity investors receive a portion of the economic attributes of the facilities, including tax 
attributes that vary over the life of the projects. Based on certain liquidation provisions of the tax equity 
structures, this could result in a net loss to AES consolidated results in periods in which the facilities report net 
income. These non cash net losses will be expected to reverse during the life of the facilities. Some of the wind 
projects are exposed to the volatility of energy prices and their revenue may change materially as energy prices 
fluctuate in their respective markets of operations.

Buffalo Gap is located in Texas and is comprised of three wind projects with an aggregate generation capacity of 
522 MW. Each wind project operates its own PPA with the exception of Buffalo Gap III. The energy price of the 
entire production of Buffalo Gap I is guaranteed by a PPA expiring in 2021. The PPA of Buffalo Gap II guarantees 
the energy price of 80% of the installed capacity while the energy price for the remaining 20% is dictated by the 
prices in the ERCOT market. The PPA of Buffalo Gap II expires in December 2017. Once the PPAs expire, the 
entire installed capacity of Buffalo Gap will be exposed to the volatility of energy prices in the ERCOT market 
which could adversely affect revenues.

Laurel Mountain is a wind project located in West Virginia with an installed capacity of 98 MW. Laurel Mountain 
does not operate under a long-term contract and sells its entire capacity and power generated into the PJM 
market. The volatility and fluctuations of energy prices in PJM have a direct impact in the results of Laurel 
Mountain. 

AES manages the wind portfolio as part of its broader investments in the U.S., leveraging operational and 
commercial resources to supplement the experienced subject matter experts in the wind industry to achieve 
optimal results.

21

•  AES Distributed Energy — AES has 103 MW of solar capacity in the U.S., located across multiple states. 

Distributed Energy's Commercial and Utility division, which comprised 89 MW of solar capacity as of December 
31, 2016, sells electricity generated by photovoltaic solar energy systems to public sector, utility, and non-profit 
entities through power purchase agreements. AES has added 33 MW of commercial and utility capacity in 2016. 
A majority of this new capacity has been financed with tax equity structures. Under these tax equity structures, 
the tax equity investors receive a portion of the economic attributes of the facilities, including tax attributes that 
vary over the life of the projects. Based on certain liquidation provisions of the tax equity structures, this could 
result in a net loss to AES consolidated results in periods in which the facilities report net income. These non 
cash net losses will be expected to reverse during the life of the facilities.

AES manages the Distributed Energy portfolio as part of its broader investments in the U.S., leveraging 
operational and commercial resources to supplement the experienced subject matter experts in the solar 
industry to achieve optimal results.

Market Structure — For the non-renewable businesses included in our additional U.S. generation facilities, 
coal and natural gas are used as the primary fuels. Coal has prices that are set by market factors internationally 
while natural gas is generally set domestically. Price variations for these fuels can change the composition of 
generation costs and energy prices in our generation businesses, and the prices of these fuels have been subject to 
volatility in recent years. 

Many of these generation businesses have entered into long-term PPAs with utilities or other offtakers. Some 

coal-fired power plant businesses in the U.S. with PPAs have mechanisms to recover fuel costs from the offtaker, 
including an energy payment that is partially based on the market price of coal. In addition, these businesses often 
have an opportunity to increase or decrease profitability from payments under their PPAs depending on such items 
as plant efficiency and availability, heat rate, ability to buy coal at lower costs through AES' global sourcing program 
and fuel flexibility. Revenue may change materially as prices in fuel markets fluctuate, but the variable margin or 
profitability should not be materially changed when market price fluctuations in fuel are borne by the offtaker. 

Regulatory Framework — Several of our generation businesses in the U.S. currently operate as QFs as 
defined under the PURPA. These businesses entered into long-term contracts with electric utilities that had a 
mandatory obligation under PURPA requirements to purchase power from QFs at the utility's avoided cost (i.e., the 
likely costs for both energy and capital investment that would have been incurred by the purchasing utility if that 
utility had to provide its own generating capacity or purchase it from another source). To be a QF, a cogeneration 
facility must produce electricity and useful thermal energy for an industrial or commercial process or heating or 
cooling applications in certain proportions to the facility's total energy output and meet certain efficiency standards. 
To be a QF, a small power production facility must generally use a renewable resource as its energy input and meet 
certain size criteria. 

Our non-QF generation businesses in the U.S. currently operate as Exempt Wholesale Generators as defined 

under EPAct 1992. These businesses, subject to approval of FERC, have the right to sell power at market-based 
rates, either directly to the wholesale market or to a third-party offtaker such as a power marketer or utility/industrial 
customer. Under the FPA and FERC's regulations, approval from FERC to sell wholesale power at market-based 
rates is generally dependent upon a showing to FERC that the seller lacks market power in generation and 
transmission, that the seller and its affiliates cannot erect other barriers to market entry and that there is no 
opportunity for abusive transactions involving regulated affiliates of the seller. To prevent market manipulation, 
FERC requires sellers with market-based rate authority to file certain reports, including a triennial updated market 
power analysis for markets in which they control certain threshold amounts of generation.

Other Regulatory Matters — The U.S. wholesale electricity market consists of multiple distinct regional 
markets that are subject to both federal regulation, as implemented by the U.S. FERC, and regional regulation as 
defined by rules designed and implemented by the RTOs, non-profit corporations that operate the regional 
transmission grid and maintain organized markets for electricity. These rules for the most part govern such items as 
the determination of the market mechanism for setting the system marginal price for energy and the establishment 
of guidelines and incentives for the addition of new capacity. See Item 1A.—Risk Factors for additional discussion 
on U.S. regulatory matters.

Environmental Regulation — For a discussion of environmental laws and regulations affecting the U.S. 

business, see Item 1.—United States Environmental and Land-Use Legislation and Regulations. 

Key Financial Drivers — U.S. Generation's financial results are driven by fuel costs and outages. The 

Company has entered into long-term fuel contracts to mitigate the risks associated with fluctuating prices. In 
addition, major maintenance requiring units to be off-line is performed during periods when power demand is 
typically lower. The financial results of U.S. Wind are primarily driven by increased production due to faster and less 
22

turbulent wind, and reduced turbine outages. In addition, PJM and ERCOT power prices impact financial results for 
the wind projects that are operating without long-term contracts for all or some of their capacity. 

Construction and Development — Planned capital projects include the AES Southland re-powering described 
above. In addition to the new construction projects, U.S. Generation performs capital projects related to major plant 
maintenance, repairs, and upgrades to be compliant with new environmental laws and regulations.

Andes SBU

Generation — Our Andes SBU has generation facilities in three countries — Chile, Colombia and Argentina. 

AES Gener, which owns all of our assets in Chile, Chivor in Colombia and TermoAndes in Argentina, as detailed 
below, is a publicly listed company in Chile. AES has a 66.7% ownership interest in AES Gener and this business is 
consolidated in our financial statements.

Chile

Business Description — In Chile, through AES Gener, we are engaged in the generation and supply of 
electricity (energy and capacity) in the two principal markets: the SIC and SING. In terms of aggregate installed 
capacity, AES Gener is the second largest generation operator in Chile with a calculated installed capacity of 4,131 
MW, excluding energy storage and TermoAndes, and a market share of approximately 18% as of December 31, 
2016.

AES Gener owns a diversified generation portfolio in Chile in terms of geography, technology, customers and 

fuel source. AES Gener's installed capacity is located near the principal electricity consumption centers, including 
Santiago, Valparaiso and Antofagasta. AES Gener's portfolio is composed of hydroelectric, coal, gas, diesel, solar 
photovoltaic and biomass facilities, that allows the businesses to operate under a variety of market and hydrological 
conditions, manage AES Gener's contractual obligations with regulated and unregulated customers and, as 
required, provide backup energy to the spot market.

AES Gener has experienced significant growth in recent years by responding to market opportunities. The 

company successfully completed a first expansion phase between 2007 and 2014 that added 6 new power plants 
totaling 1,677 MW. It continued to grow in Chile through its second expansion phase that will add 1,236 MW. As of 
the end of 2016, AES Gener has completed the construction of Guacolda Unit 5 (152 MW), Cochrane (532 MW) 
and Andes Solar (21 MW). Additionally, we continue to advance in the construction of the 531 MW Alto Maipo run-
of-the-river hydroelectric plant in the SIC.

Our commercial policy in Chile aims to maximize margin while reducing cash flow volatility. In order to achieve 

this, we contract a significant portion of our baseload capacity, currently coal and hydroelectric, under long-term 
agreements with a diversified customer base, that includes both regulated and unregulated customers. Power 
plants that are not considered within our baseload capacity (higher variable cost units, mainly diesel and gas fired 

24

units) operate during scarce system supply conditions, such as dry hydrological conditions and plant outages, 
selling their energy in the spot market. In Chile, sales on the spot market are made only to other generation 
companies (entities that are members of the Economic Load Dispatch Center - "CISEN") at the system marginal 
cost. In anticipation of the SIC and SING interconnection, the new Transmission Law created the CISEN, an entity 
that will merge both system operators into one. 

AES Gener currently has long-term contracts, with an average remaining term of approximately 11 years, with 
regulated distribution companies and unregulated customers, such as mining and industrial companies. In general, 
these long-term contracts include both fixed and variable payments along with indexation mechanisms that 
periodically adjust prices based on the generation cost structure related to the United States Consumer Price Index, 
the international price of coal, and in some cases, with pass-through of fuel and regulatory costs, including changes 
in law.

In addition to energy payments, AES Gener also receives firm capacity payments for contributing to the 

system's ability to meet peak demand. These payments are added to the final electricity price paid by both 
unregulated and regulated customers. In each system, the CISEN annually determines the firm capacity amount 
allocated to each power plant. A plant's firm capacity is defined as the capacity that it can guarantee at peak hours 
during critical conditions, such as droughts, taking into account statistical information regarding maintenance 
periods and water inflows in the case of hydroelectric plants. The capacity price is fixed by the National Energy 
Commission in the semiannual node price report and indexed to the United States Consumer Price Index and other 
relevant indices.

Market Structure — Chile has two main power systems, largely as a result of its geographic shape and size. 

The SIC is the largest of these systems, with an installed capacity of 17,543 MW as of December 31, 2016. The 
SIC serves approximately 92% of the Chilean population, including the densely populated Santiago Metropolitan 
Region, and represents 75% of the country's electricity demand. The SING serves about 6% of the Chilean 
population, representing 25% of Chile's electricity consumption, and mainly supplies mining companies.

In 2016, thermoelectric generation represented 67% of the total generation in Chile. In the SIC, thermoelectric 

generation represents 48% of installed capacity, required to fulfill demand not satisfied by hydroelectric output and 
is critical to guaranteeing reliable and dependable electricity supply under dry hydrological conditions. In the SING, 
which includes the Atacama Desert, the driest desert in the world, thermoelectric capacity represents 92% of 
installed capacity. The fuels used for generation, mainly coal, diesel and LNG, are indexed to international prices.

In the SIC, where hydroelectric plants represent a large part of the system's installed capacity, hydrological 

conditions largely influence plant dispatch and, therefore, spot market prices, given that river inflows, snow melting 
and initial water levels in reservoirs largely determine the dispatch of the system's hydroelectric and thermoelectric 
generation plants. Rainfall and snowfall occur in Chile principally in the southern cone winter season (June to 
August) and during the remainder of the year precipitation is scarce. When rain is abundant, energy produced by 
hydroelectric plants can amount to more than 70% of total generation. In 2016 hydroelectric generation represented 
36% of total energy production within the SIC, and 27% of the country’s total energy production.

Solar and wind installed capacity represents a small but growing part of the total capacity installed. In the SIC, 

solar accounts for 3% of the power generation and 7% of the system’s installed capacity while in the SING solar 
accounts for 4% of the power generation and 6% of the system’s capacity. As for wind, in the SIC, wind contributes 
with 4% of the power generation and 7% of the system’s capacity, while in the SING wind generation represents 1% 
of the power generation and with 2% of the system’s capacity.

Regulatory Framework — The government entity that has primary responsibility for the Chilean electricity 

system is the Ministry of Energy, acting directly or through the National Energy Commission and the 
Superintendency of Electricity and Fuels. The electricity sector is divided into three segments: generation, 
transmission and distribution. In general terms, generation and transmission expansion are subject to market 
competition, while transmission operation and distribution, are subject to price regulation. The transmission 
segment consists of companies that transmit the electricity produced by generation companies at high voltage. The 
individual and joint participation of companies operating in any other segment of the electricity sector cannot exceed 
8% and 40%, respectively, of the total investment value of the national transmission system. 

Companies in the SIC and the SING that own generation, transmission, sub-transmission or additional 

transmission facilities, as well as unregulated customers directly connected to transmission facilities, are 
coordinated through the CISEN, which minimizes the operating costs of the electricity system, while meeting all 
service quality and reliability requirements. The principal purpose of the CISEN is to ensure that the most efficient 
electricity generation available to meet demand is dispatched to customers. The CISEN dispatches plants in merit 
order based on their variable cost of production, allowing for electricity to be supplied at the lowest available cost.

25

All generators can commercialize energy through contracts with distribution companies for their regulated and 

unregulated customers or directly with unregulated customers. Unregulated customers are customers whose 
connected capacity is higher than 2MW. Customers with connected capacity between 0.5 MW and 2.0 MW can opt 
for a Regulated or Unregulated regime for a minimum period of four years. By law, both regulated and unregulated 
customers are required to purchase all of their electricity requirements under contract. Generators may also sell 
energy to other power generation companies on a short-term basis. Power generation companies may engage in 
contracted sales among themselves at negotiated prices outside the spot market. Electricity prices in Chile, under 
contract and on the spot market, are denominated in U.S. Dollars, although payments are made in Chilean Pesos.

In July 2016, modifications to the Transmission Law were enacted. This Law establishes that the transmission 

system will be completely paid for by the end-users, gradually allocating the costs on the demand side from year 
2019 through 2034.

Environmental Regulation — In 2011, a regulation on air emission standards for thermoelectric power plants 

became effective. This regulation provides for stringent limits on emission of PM and gases produced by the 
combustion of solid and liquid fuels, particularly coal. For existing plants, including those currently under 
construction, the new limits for PM emissions went into effect at the end of 2013, and the new limits for SO2, NOx 
and mercury emission were in effect since mid-2016, except for those plants operating in zones declared saturated 
or latent zones (areas at risk of or affected by excessive air pollution), where these emission limits became effective 
in June 2015. In order to comply with the new emission standards, AES Gener initiated investments in Chile at its 
older coal facilities (Ventanas I and II and Norgener I and II, constructed between 1964 and 1997) in 2012. As of 
December 31, 2016, AES Gener has concluded investments of approximately $229 million in order to comply within 
the required time frame. Additionally, its equity method investee Guacolda started the installation of new emission 
control equipment during 2013, and concluded investments of approximately $209 million in order to comply within 
the required time frame.

On March 29, 2016, the Health Ministry enacted Supreme Decree N°43 (“DS 43”) ruling “Storage of 
Hazardous Materials”, modifying the current applicable rules. This regulation will become fully effective in March 
2018 for structural improvements of currently authorized storage facilities. The estimated investment required to 
comply with DS 43 would be approximately $15 million.

During 2016, the Environmental Ministry worked on upgrading the Atmospheric Decontamination Plans for 

Santiago, Ventanas and Huasco areas, each of which, as of December 31, 2016, are currently under different 
stages of progress. Nueva Renca, Ventanas and Guacolda power plants may require an improvement of their 
operational practices and additional investments to meet the expected new requirements during the year following 
the enactment of the Decontamination Plan, which is expected for mid 2017.

Chilean law requires every electricity generator to supply a certain portion of its total contractual obligations 
with Non-conventional Renewable Energy ("NCREs"). In October 2013, the NCRE law was amended, increasing 
the NCRE requirements. The law distinguishes between energy contracts executed before and after July 1, 2013. 
For contracts executed between August 31, 2007 and July 1, 2013, the NCRE requirement is equal to 5% in 2014 
with annual contract increases of 0.5% until reaching 10% in 2024. The NCRE requirement for contracts executed 
after July 1, 2013 is equal to 5% in 2013, with annual increases of 1% thereafter until reaching 12% in 2020, and 
subsequently annual increases of 1.5% until it is equal to 20% in 2025. Generation companies are able to meet this 
requirement by developing their own NCRE generation capacity (wind, solar, biomass, geothermal and small 
hydroelectric technology), purchasing NCREs from qualified generators or by paying the applicable fines for non-
compliance. AES Gener currently fulfills the NCRE requirements by utilizing AES Gener's own solar and biomass 
power plants and by purchasing NCREs from other generation companies. It has sold certain water rights to 
companies that are developing small hydro projects, entering into power purchase agreements with these 
companies in order to promote development of these projects, while at the same time meeting the NCRE 
requirements. At present, AES Gener is in the process of negotiating additional NCRE supply contracts to meet the 
future requirements. 

In September 2014 a new tax law was enacted. The new law introduces an emission tax, or "green tax", that 

assesses the emissions of PM, SO2, NOx and CO2 produced for installations with an installed capacity over 50 MW. 
The first annual payment shall be made in April 2018 for emissions produced in 2017. In the case of CO2, the tax 
will be equivalent to $5 per ton emitted. In the SING, all PPAs have "change of law" clauses, which would allow the 
company to transfer this cost to customers. In the SIC, costs can only be passed through to unregulated customers, 
as existing PPAs with distribution companies do not have change of law clauses. According to its PPAs, the 
company is currently discussing the pass-through mechanism with each client. Additionally, the new tax systems 
introduced by the new tax laws enacted in February 2016 will be effective from January 1, 2017 onwards. The 
statutory income tax rate for most of our Chilean businesses will increase from 25% to 25.5% in 2017 and to 27% 
26

for 2018 and future years. See Item 7.—Management's Discussion and Analysis of Financial Condition and Results 
of Operations—Critical Accounting Policies and Estimates—Income Taxes for further details of the impacts of these 
new laws.

In June 2015, the Chilean government published Decree N°7/2015, which allows the export of energy 
generated by plants not dispatched in the SING to Argentina using the transmission line connecting the SING with 
the SADI. This transmission line is owned by AES Gener and has a capacity of approximately 600 MW, but will be 
operated at 200 MW according to the government permit and related technical studies. AES Gener signed an 
agreement with CAMMESA and Chilean generators to export electricity to Argentina. In December 2016, Decree N° 
7/2015 was amended to allow the export of energy generated by plants dispatched into the SING to Argentina. 
During 2016, energy exported to Argentina reached 102 GWh.

Key Financial Drivers — Hedge levels at Gener provide some certainty and clarity on the underlying financial 

drivers. In addition, financial results are likely to be driven by many factors including, but not limited to: 

•  Dry hydrology scenarios reduce hydro generation 

•  Forced outages may impact earnings
•  Changes in current regulatory rulings could alter the ability to pass through or recover certain costs

•  AES is exposed to the fluctuation of the Chilean peso, which may pose a risk to earnings; our hedging 

strategy reduces this risk, but some residual risk to earnings remains

•  Tax policy changes
•  Current legislation is trending towards promoting renewable energy and strengthening regulations on thermal 

generation assets, posing a risk to future coal margins

•  Market price risk when re-contracting 

Construction and Development — Since 2007, AES Gener has constructed and commissioned approximately 

2,400 MW of new capacity, representing a significant portion of the capacity increase in the SIC and SING during 
the period. During 2016, AES Gener achieved important milestones related to the construction of their projects:

•  Cochrane project began operations (Unit 2 on October 12 and Unit 1 on July 9) adding 532 MW to the SING.
•  Cochrane Energy Storage began operations in October 2016 adding 20 MW of batteries contributing to system 

stability in the SING.

•  Andes Solar with 21 MW began operations in May 2016

Additionally, in the SIC, we continue advancing in the construction of our Alto Maipo project, a 531 MW two 

unit run-of-river hydroelectric power plant, adjacent to our existing Alfalfal plant, located 50 km from Santiago. Alto 
Maipo is the largest project in construction in the SIC market and it includes 67 km of tunnel works, two caverns, 17 
km of transmission lines as part of the construction, and is 90% underground. Alto Maipo has three main 
contractors and covers three adjacent valleys in the Chilean Andes. As of today, the project employs approximately 
4,300 people and expects to reach a peak close to 4,500. The project units are scheduled to reach commercial 
operation in the first half of 2019.

We are expanding our business by evaluating opportunities in the desalination business line through two 
initiatives: i) brownfield projects, which take advantage of existing infrastructure in thermoelectric power plants 
(marine works, easy access to power, strategic location, permits, etc.), providing shorter development time lines 
and more competitive water tariffs to offtakers; and ii) greenfield projects, mainly for mining companies which either 
purchase industrial water through water purchase agreements, or either invite external companies to compete in a 
bidding process to develop a project under a build-own-operate-and-transfer scheme where the water facility along 
its pipeline is transferred to the mining operation at the end of a defined period. In Chile, most of the water demand 
comes from mining operations, either directly or indirectly (their service providers), hence negative outlooks in the 
mineral markets have translated in the postponement of most of the mining projects and their corresponding water 
demands.

Colombia

Business Description — We operate in Colombia through AES Chivor, a subsidiary of AES Gener, who owns a 

hydroelectric plant with an installed capacity of 1,000 MW, and Tunjita, a 20 MW run-of-river hydroelectric, both 
located approximately 160 km east of Bogota. As of December 31, 2016, AES Chivor's net power production in 
reached 4,373 GWh. AES Chivor’s installed capacity accounted for approximately 6.1% of system capacity by the 
end of the year. Chivor remains dependent on prevailing hydrological conditions in the region in which it operates. 
Hydrological conditions largely influence generation and the spot prices at which AES Chivor sells its non-

27

contracted generation in Colombia.

AES Chivor's commercial strategy aims to reduce margin volatility by selling a significant portion of the 
expected generation under short term contracts, mainly with distribution companies. These contracts are awarded 
in public auctions and normally last from one to three years. The remaining generation is sold on the spot market to 
other generation and trading companies at the system marginal cost, allowing us to maximize the operating margin. 
Additionally, AES Chivor receives reliability payments to compensate for the plant availability during periods of 
power scarcity, such as adverse hydrological conditions, in order to prevent power shortages. 

Market Structure — Electricity supply in Colombia is concentrated in one main system, the SIN which 
encompasses one-third of Colombia's territory, providing coverage to 97% of the country's population. The SIN's 
installed capacity totaled 16,690 MW as of December 31, 2016, comprised of 70% hydroelectric generation, 29% 
thermoelectric generation and 1% other. The dominance of hydroelectric generation and the marked seasonal 
variations in Colombia's hydrology result in price volatility in the short-term market. In 2016, 72% of total energy 
demand was supplied by hydroelectric plants with the remaining supply from thermoelectric generation of 27% and 
cogeneration and self-generation power of 1%. From 2003 to 2016, electricity demand in the SIN has grown at a 
compound annual growth rate of 2.9% and the Mining and Energetic Planning Unit projects an average compound 
annual growth rate in electricity demand of 3.0% per year for the next 10 years.

Regulatory Framework — Since 1994, the electricity sector in Colombia has operated under a competitive 

market framework for the generation and sale of electricity and a regulated framework for transmission and 
distribution. The distinct activities of the electricity sector are governed by various laws as well as the regulations 
and technical standards issued by the CREG. Other government entities that play an important role in the electricity 
industry include the Ministry of Mines and Energy, which defines the government's policy for the energy sector; the 
Public Utility Superintendency of Colombia, which is in charge of overseeing and inspecting the utility companies; 
and the Mining and Energetic Planning Unit, which is in charge of planning the expansion of the generation and 
transmission network. 

The generation sector is organized on a competitive basis with companies selling their generation in the 

wholesale market at the short-term price or under bilateral contracts with other participants, including distribution 
companies, generators and traders, and unregulated customers at freely negotiated prices. Generation companies 
must submit price bids and report the quantity of energy available on a daily basis. The National Dispatch Center 
dispatches generators in merit order based on bid offers in order to ensure that demand will be satisfied by the 
lowest cost combination of available generating units.

Regulatory Framework - Tax Regulation — On December 29, 2016, Law 1819 was enacted in Colombia, 
which introduced a tax reform with several changes in the Colombian tax system, and became effective on January 
1, 2017. This tax reform reduced the statutory corporate tax rate of companies to 40% in 2017, 37% in 2018, and 
33% in 2019 onwards. The law also created a new withholding tax on dividend distributions based on a tax rate of 
5%, applicable on distribution of Colombian profits generated from the taxable year 2017 onwards. 

Other Regulatory Considerations — After the phenomenon of El Niño put the energy supply at risk, regulatory 

agencies and the government have carried out various studies to make adjustments to the market. The subjects 
susceptible to revision include the following: 

•  Adjustments to the scarcity price so that it reflects a true value of thermal plants that operate in periods of crisis. 

•  A plan to implement an option to assign firm energy obligations without the need for reliability auctions but with 

obligation of signing energy contracts with non-regulated demand. 

•  Possible participation of renewable plants in the market and its effect in the formation of prices and operation of 

the market. 

•  The implementation of the standardized contract market, and 

•  The possibility of entering into the intraday markets and markets of the previous day are still being considered. 

Other topics that the regulator could analyze in 2017, but with a secondary priority are: An international 

interconnection scheme, review of the AGC market and analysis of other ancillary services, and possible 
modification of the current regulation for emergency situations.

Key Financial Drivers — Hydrological conditions largely influence Chivor's generation level. Maintaining the 

appropriate contract level, while working to maximize revenue, through sale of excess generation, is key to Chivor's 
results of operations Hedge levels at Chivor provide certainty and clarity on the underlying financial drivers, hedging 
the net cash flows of Chivor, up to 90%. In addition to hydrology financial results are likely to be driven by many 
factors including, but not limited to: 

28

•  Forced outages may impact earnings

•  AES is exposed to fluctuation of the Colombian peso, which pose a risk to earnings; our hedging strategy 

reduces this risk, but some residual risk to earnings remains

•  Chivor has exposure to the spot market as hedge levels are lower in the future

Construction and Development — In Colombia, AES Gener completed the construction of the Tunjita project in 

June 2016 that added 20 MW of capacity to the Chivor plant.

Argentina

Business Description — As of December 31, 2016, AES Argentina operates 4,105 MW which represents 12% 

of the country's total installed capacity. The installed capacity in the SADI includes the TermoAndes plant, a 
subsidiary of AES Gener, which is connected both to the SADI and the Chilean SING. AES Argentina has a 
diversified generation portfolio of ten generation facilities, comprised of 68% thermoelectric and 32% hydroelectric 
capacity. All of the thermoelectric capacity has the capability to burn alternative fuels. Approximately 76% of the 
thermoelectric capacity can operate with natural gas or diesel oil, and the remaining 24% can operate with natural 
gas, fuel oil, or coal.

AES Argentina primarily sells its production to the wholesale electric market where prices are largely 
regulated. In 2016, approximately 94% of the energy was sold in the wholesale electric market and 6% was sold 
under contract, as a result of the Energy Plus sales made by TermoAndes. 

All of the thermoelectric facilities not affected by the Resolution 95/2013, a regulation passed in March 2013 
discussed below, including the portion of TermoAndes plant committed to Energy Plus Contracts, are able to use 
natural gas and receive gas supplied through contracts with Argentine producers. In recent years, gas supply 
restrictions in Argentina, particularly during the winter season, have affected some of the plants, such as the 
TermoAndes plant. The TermoAndes plant commenced operations in 2000, selling exclusively into the Chilean 
SING. In 2008, following requirements from the Argentine authorities, TermoAndes connected its two gas turbines 
to the SADI, while maintaining its steam turbine connected to the SING. However, since December 2011, 
TermoAndes has been selling the plant's full capacity in the SADI. 

Market Structure — The SADI electricity market is managed by CAMMESA. As of December 31, 2016, the 

installed capacity of the SADI totaled 33,901 MW. In 2016, 66% of total energy demand was supplied by 
thermoelectric plants, 26% by hydroelectric plants and 8% from nuclear, wind and solar plants.

Thermoelectric generation in the SADI is principally fueled by natural gas. However, since 2004 due to natural 
gas shortages, in addition to increasing electricity demand, the use of alternative fuels in thermoelectric generation, 
such as oil and coal, has increased. Given the importance of hydroelectric facilities in the SADI, hydrological 
conditions determining river flow volumes and initial water levels in reservoirs largely influence hydroelectric and 
thermoelectric plant dispatch. Rainfall occurs principally in the southern cone winter season (June to August).

Regulatory Framework — The Argentine regulatory framework divides the electricity sector into generation, 

transmission and distribution. The wholesale electric market is made up of generation companies, transmission 
companies, distribution companies and large customers who are allowed to buy and sell electricity. Generation 
companies can sell their output in the short-term market or to customers in the contract market. CAMMESA is 
responsible for dispatch coordination and determination of short-term prices. The Electricity National Regulatory 
Agency is in charge of regulating public service activities and the Ministry of Federal Planning, Public Investment 
and Services, through the Energy Secretariat, regulates system dispatch and grants concessions or authorizations 
for sector activities. 

Since 2001, significant modifications have been made to the electricity regulatory framework. These 

modifications include the freezing of tariffs, the cancellation of inflation adjustment mechanisms and the introduction 
of a complex pricing system in the wholesale electric market, which have materially affected electricity generators, 
transporters and distributors, and generated substantial price differences within the market. Since 2004, as a result 
of energy market reforms and overdue accounts receivables owed by the government to generators operating in 
Argentina, AES Argentina contributed certain accounts receivables to fund the construction of new power plants 
under FONINVEMEM agreements. These receivables accrue interest and are collected in monthly installments over 
10 years once the related plants begin operations. At this point, three funds have been created to construct three 
facilities. The three plants are operating and payments are being received. AES Argentina will receive a pro rata 
ownership interest in these newly built plants once the accounts receivables have been paid. See Item 7.—Capital 
Resources and Liquidity—Long-Term Receivables and Note 7—Financing Receivables for further discussion of 
receivables in Argentina.

29

In March 2013, the Secretariat of Energy released Resolution 95/2013, which affects the remuneration of 
generators whose sales prices had been frozen since 2003. This regulation is applicable to generation companies 
with certain exceptions. It defined a compensation system based on compensating for fixed costs, non-fuel variable 
costs and an additional margin. Resolution 95/2013 converted the Argentine electric market to an "average cost" 
compensation scheme. 

Thermal units must achieve an availability target, which varies by technology, in order to receive full fixed cost 

revenues. The Resolution also established that all fuels, except coal, are to be provided by CAMMESA. 
Thermoelectric natural gas plants not affected by the Resolution, such as TermoAndes, are able to purchase gas 
directly from the producers for Energy Plus sales.

In May 2014, the Argentine government passed Resolution No. 529/214 ("Resolution 529") which retroactively 

updated the prices of Resolution 95/2013 to February 1, 2014, changed target availability and added a 
remuneration for non-periodic maintenance. This remuneration is aimed to cover the expenses that the generator 
incurs when performing major maintenances in its units. Since 2014, this resolution has been updated annually, the 
most recent of which was issued in March 2016. 

On February 2, 2017, the Ministry of Energy issued Resolution 19/2017 establishing changes to the Energia 

Base price framework. Effective in February 2017, the framework will maintain the current tolling agreement 
structure, as fuels will continue to be sourced by CAMMESA. A key change will be introduced to the tariff structure 
which will now have prices set in USD and also eliminates all future non-cash retention of margins.

In December 2015, the finance minister lifted foreign currency controls, allowing the peso to float under the 
administration of Argentinean Central Bank. The newly freed currency fell by more than 30%. Over the course of 
2016, the Argentinean Peso devalued by approximately 22%. At December 31, 2016, all transactions at our 
businesses in Argentina were translated using the official exchange rate published by the Argentine Central Bank. 
See Note 7—Financing Receivables in Item 8.—Financial Statements and Supplementary Data of this Form 10-K 
for further information on the long-term receivables. Further weakening of the Argentine Peso and local economic 
activity could cause significant volatility in our results of operations, cash flows, the ability to pay dividends to the 
Parent Company, and the value of our assets.

Key Financial Drivers — Financial results are likely to be driven by many factors including, but not limited to: 

•  Forced outages may impact earnings
•  FX exposure to fluctuations of the Argentine Peso
•  Hydrology
•  Timely collection of FONINVEMEM installment and outstanding receivables (See Note 7—Financing 

Receivables in Item 8.—Financial Statements and Supplementary Data for further discussion)

Business Description — Eletropaulo distributes electricity to the greater São Paulo area, Brazil's main 
economic and financial center. AES owns 17% of the economic interest in Eletropaulo, our partner, BNDES, owns 
19% and the remaining shares are publicly held or held by government-related entities. On December 30, 2016 
AES purchased par shares from BNDES and increased its participation in Eletropaulo from 16% to 17%. AES is the 
controlling shareholder and manages and consolidates this business. Eletropaulo holds a 30-year concession that 
expires in 2028. In December 2016, Eletropaulo underwent a corporate restructuring which is expected to, among 
other things, prepare for the listing of its shares on the Novo Mercado, a segment of the Brazilian stock exchange.

Regulatory Framework — In Brazil, ANEEL, a government agency, sets the tariff for each distribution company 

based on a return on asset base methodology, which also benchmarks operational costs against other distribution 
companies. The tariff charged to regulated customers consists of two elements: (i) pass-through of non-
manageable costs under a determined methodology ("Parcel A"), including energy purchase costs, sector charges 
and transmission and distribution system expenses; and (ii) a manageable cost component ("Parcel B"), including 
operation and maintenance costs (defined by ANEEL), recovery of investments and a component for a return to the 
distributor. The return to distributors is calculated as the net asset base multiplied by the regulatory weighted-
average cost of capital, which is set for all industry participants during each tariff reset cycle. The current regulatory 
weighted-average cost of capital for Eletropaulo, after tax, is 8.1%. 

Each year ANEEL reviews each distributor's tariff for an annual tariff adjustment. The annual tariff adjustments 

allow for pass-through of Parcel A costs and inflation impacts on Parcel B costs, adjusted for expected efficiency 
gains and quality performances. Distribution companies are required to contract between 100% and 105% of 
anticipated energy needs through the regulated auction market. If contracted levels fall below required levels 
distribution companies may be subject to limitations on the pass-through treatment of energy purchase costs as 
well as penalties. As the costs incurred on energy purchases made by our distribution company are passed through 

31

to customers with adjustments on a yearly basis, working capital can be sensitive to significant increases in energy 
prices. In order to reduce potential working capital needs, in 2015 ANEEL established the tariff flag mechanism, 
which allows temporary tariff changes to customers on a monthly basis depending on energy purchase prices. The 
resources collected by the tariff flag mechanism are centralized in an account and shared among distribution 
companies in proportion to their respective exposure to the spot market. 

Every four years, ANEEL resets each distributor's tariff to incorporate the revised regulatory weighted-average 

cost of capital and determination of the distributor's net asset base as well as operational costs. Eletropaulo's tariff 
reset occurs every four years and the next tariff reset will be in July 2019. The 4th Tariff Reset for AES Eletropaulo 
occurred on July 4, 2015, representing an average tariff increase of 15.23%.

Between the tariff reset periods, the regulator applies the annual adjustments. On July 4, 2016 ANEEL 

approved a negative tariff adjustment for Eletropaulo, mainly due to a decrease in energy purchase and sector 
charges costs. The average tariff decrease was 8.1%.

In 2013, ANEEL challenged the parameters of a tariff reset for Eletropaulo implemented in July 2012 and 

retroactive to 2011. ANEEL asserted that during the period between 2007 and 2011, certain assets that were 
included in the regulatory asset base should not have been included and that Eletropaulo should refund customers 
for the return on the disputed assets earned during this period. On December 17, 2013, ANEEL determined, at the 
administrative level, that Eletropaulo should adjust the prior 2007-2011 regulatory asset base and refund customers 
in the amount of $269 million over a period of up to four tariff processes beginning in July 2014. The Company 
recognized a regulatory liability of approximately $269 million in 2013, since ANEEL had compelled the Company to 
refund customers, and started reimbursing customers in July 2014. Eletropaulo filed for an administrative appeal 
requesting ANEEL to reconsider its decision and requested that the decision be suspended until the appeal process 
is completed. The injunction was granted and, although for a period was suspended, it has been restored and in 
effect since December 2014.

Given ANEEL's failure to suspend the injunction through the appeals process in the Brazilian courts thus far, 

the tariff reset resulted in management's reassessment of the probability of refunding customers these disputed 
amounts. Therefore, at this point, the Company considers it only reasonably possible that Eletropaulo will be 
required to refund these amounts to customers prior to the ultimate resolution of the pending court case. As a result, 
during 2015, the Company reversed the remaining regulatory liability for this contingency of $161 million. 
Eletropaulo believes it has meritorious arguments on this matter and will continue to pursue its objections to 
ANEEL's rulings vigorously, however there can be no assurance that Eletropaulo will prevail.

Key Financial Drivers — Eletropaulo's financial results is likely to be driven by many factors including, but not 

limited to: 

•  Hydrology, impacting quantity of energy sold and energy purchased
•  Brazilian economic scenario and tariff increases, impacting energy consumption growth, losses and 

delinquency

•  Quality indicators recovery plan
•  Ability of Eletropaulo to pass through costs via productivity gains
•  Ability of Eletropaulo to solve involuntary exposure

•  Capital structure optimization to reduce leverage and interest costs

•  The CTEEP Eletrobrás case (see Item 3.—Legal Proceedings for further information)

Eletropaulo is affected by the demand for electricity, which is driven by economic activity, weather patterns 

and customers' consumption behavior. Operating performance is also driven by the quality of service, efficient 
management of operating and maintenance costs as well as the ability to control non-technical losses. Finally, 
annual tariff adjustments and periodic tariff resets by ANEEL impact results from operations. 

Brazil Generation

Business Description — Tietê has a portfolio of 12 hydroelectric power plants with total installed capacity of 
2,658 MW in the state of São Paulo. Tietê was privatized in 1999 under a 30-year concession expiring in 2029. AES 
owns a 24% economic interest in Tietê, our partner, the BNDES, owns 28% and the remaining shares are publicly 
held or held by government-related entities. AES is the controlling shareholder and manages and consolidates this 
business.

Tietê sold nearly 100% of its physical guarantee, approximately 11,194 GWh, to Eletropaulo under a long-term 

PPA, which expired in December 2015. The contract was price-adjusted annually for inflation, and as of December 

32

31, 2015, the price was R$218/MWh. After the expiration of contract with Eletropaulo, Tietê's strategy is to contract 
most of its physical guarantee, as described in Regulatory Framework section below, and sell the remaining portion 
in the spot market. Tietê's strategy is reassessed from time to time according to changes in market conditions, 
hydrology and other factors. Tietê has been continuously selling its available energy from 2016 forward through 
medium-term bilateral contracts of three to five years. 

As of December 31, 2016, Tietê's contracted portfolio position is 95% and 88% with average prices of R$157/
MWh and R$159/MWh (inflation adjusted until December 2016) for 2016 and 2017, respectively. As Brazil is mostly 
a hydro-based country with energy prices highly tied to the hydrological situation, the deterioration of the hydrology 
since the beginning of 2014 caused an increase in energy prices going forward. Tietê is closely monitoring and 
analyzing system supply conditions to support energy commercialization decisions. 

Under the concession agreement, Tietê has an obligation to increase its capacity by 15%. Tietê, as well as 

other concession generators, have not yet met this requirement due to regulatory, environmental, hydrological and 
fuel constraints. The state of São Paulo does not have a sufficient potential for wind power and only has a small 
remaining potential for hydro projects. As such, the capacity increases in the state will mostly be derived from 
thermal gas capacity projects. Due to the highly complex process to obtain an environmental license for coal 
projects, Tietê decided to fulfill its obligation with gas-fired projects in line with the federal government plans. 
Petrobras refuses to supply natural gas and to offer capacity in its pipelines and regasification terminals. Therefore, 
there are no regulations for natural gas swaps in place, and it is unfeasible to bring natural gas to AES Tietê. A legal 
case has been initiated by the state of São Paulo requiring the investment to be performed. Tietê is in the process 
of analyzing options to meet the obligation.

Uruguaiana is a 640 MW gas-fired combined cycle power plant located in the town of Uruguaiana in the state 

of Rio Grande do Sul, commissioned in December 2000. AES manages and has a 46% economic interest in the 
plant with the remaining interest held by BNDES. The plant's operations were suspended in April 2009 due to the 
unavailability of gas. AES has evaluated several alternatives to bring gas supply on a competitive basis to 
Uruguaiana. One of the challenges is the capacity restrictions on the Argentinean pipeline, especially during the 
winter season when gas demand in Argentina is very high. The plant operated on a short-term basis during 
February and March 2013, March through May 2014, and February through May 2015 due to the short-term supply 
of LNG for the facility. The plant did not operate in 2016. Uruguaiana continues to work toward securing gas on a 
long-term basis.

Market Structure — Brazil has installed capacity of 150,136 MW, which is 65% hydroelectric, 19% thermal and 

16% renewable (biomass and wind). Brazil's national grid is divided into four subsystems. Tietê is in the Southeast 
and Uruguaiana is in the South subsystems of the national grid.

Regulatory Framework — In Brazil, the Ministry of Mines and Energy determines the maximum amount of 

energy that a plant can sell, called physical guarantee, which represents the long-term average expected energy 
production of the plant. Under current rules, physical guarantee can be sold to distribution companies through long-
term regulated auctions or under unregulated bilateral contracts with large consumers or energy trading companies. 

The National System Operator ("ONS") is responsible for coordinating and controlling the operation of the 
national grid. The ONS dispatches generators based on hydrological conditions, reservoir levels, electricity demand 
and the prices of fuel and thermal generation. Given the importance of hydro generation in the country, the ONS 
sometimes reduces dispatch of hydro facilities and increases dispatch of thermal facilities to protect reservoir levels 
in the system. 

In Brazil, the system operator controls all hydroelectric generation dispatch and reservoir levels. A mechanism 

known as the Energy Reallocation Mechanism ("MRE") was created to share hydrological risk across MRE hydro 
generators. If the hydro plants generate less than the total MRE physical guarantee, the hydro generators may 
need to purchase energy in the short-term market to fulfill their contract obligations. When total hydro generation is 
higher than the total MRE physical guarantee, the surplus is proportionally shared among its participants and they 
are able to make extra revenue selling the excess energy on the spot market. The consequences of unfavorable 
hydrology are (i) thermal plants more expensive to the system being dispatched, (ii) lower hydropower generation 
with deficits in the MRE and (iii) high spot prices. ANEEL defines the spot price cap for electricity in the Brazilian 
market. The spot price caps as defined by ANEEL and average spot prices by calendar year are as follows (R$/
MWh):

Key Financial Drivers — As the system is highly dependent on hydroelectric generation, Tietê and Uruguaiana 
are are affected by the hydrology in the overall sector. They are also affected by the availability of Tietê's plants and 
reliability of the Uruguaiana facility. The availability of gas is also a driver for continued operations at Uruguaiana. 
Tietê's financial results are likely to be driven by many factors including, but not limited to:

•  Hydrology, impacting quantity of energy generated in MRE

•  Demand growth
•  Re-contracting price

•  Asset management and plant availability
•  Cost management

•  Ability to execute on its growth strategy

MCAC Utilities

El Salvador

Business Description — AES is the majority owner of four of the five distribution companies operating in El 

Salvador. The distribution companies are operated by AES on an integrated basis under a single management 
team. AES El Salvador's territory covers 77% of the country. AES El Salvador accounted for 4,151 GWh of market 
energy purchases during 2016, or about 63% market share of the country's total energy purchases. 

MCAC Generation

Dominican Republic 

Business Description — AES Dominicana consists of three operating subsidiaries, Itabo, Andres and DPP. 
AES has 24% of the system capacity of 850 MW and supplies approximately 37% of energy demand through these 
generation facilities. AES has a strategic partnership with the Estrella and Linda Groups ("Estrella-Linda"), an 
investor group based in the Dominican Republic. Estrella-Linda is a consortium of two leading Dominican industrial 
groups: Estrella and Grupo Linda. The two partners manage a diversified business portfolio, including construction 
services, cement, agribusiness, metalwork, plastics, textiles, paints, transportation, insurance and media.

Itabo is 45% owned by AES, 5% by Estrella-Linda, 49.97% owned by FONPER, a government-owned utility 

and the remaining 0.03% is owned by employees. Itabo owns and operates two thermal power generation units with 
a total of 295 MW of installed capacity. Itabo's PPAs with government-owned distribution companies expired in July 
2016 and thus two new short term contracts with Ede Sur and Ede Este were signed until new long term contracts 
take place. The Dominican Corporation of State Electrical Companies is sponsoring a bidding process, released in 

35

August 2016, which is expected to be awarded in April 2017 in order to secure supply and competitive pricing for 
actual and future distribution energy requirements. The existing business strategy is to secure between 80% and 
85% of the open position through new PPAs with distribution companies and large users. Price and PPA structure 
will be subject to the terms of the bidding process.

Andres and DPP are owned 90% by AES and 10% by Estrella-Linda. Andres has a combined cycle gas 
turbine and generation capacity of 319 MW as well as the only LNG import facility in the country, with 160,000 cubic 
meters of storage capacity. DPP (Los Mina) has two open cycle natural gas turbines and generation capacity of 236 
MW. Both Andres and DPP have in aggregate 555 MW of installed capacity, of which 450 MW is mostly contracted 
until 2018 with government-owned distribution companies and large customers. 

AES Dominicana has a long-term LNG purchase contract through 2023 for 33.6 trillion btu/year with a price 

linked to NYMEX Henry Hub. The LNG contract terms allow the diversion of the cargoes to various markets in Latin 
America. These plants capitalize on the competitively-priced LNG contract by selling power where the market is 
dominated by fuel oil-based generation. Andres has a long-term contract to sell re-gasified LNG to industrial users 
within the Dominican Republic using compression technology to transport it within the country thereby capturing 
demand from industrial and commercial customers.

Market Structure - Electricity and Natural Gas — The Dominican Republic has one main interconnected 
system with approximately 3,553 MW of installed capacity, composed primarily of thermal generation (80%), 
hydroelectric power plants (17%) and wind plants (3%).

Regulatory Framework — The regulatory framework in the Dominican Republic consists of a decentralized 
industry including generation, transmission and distribution, where generation companies can earn revenue through 
short- and long-term PPAs, ancillary services and a competitive wholesale generation market. All electric 
companies (generators, transmission and distributors), are subject to and regulated by the General Electricity Law.

Two main agencies are responsible for monitoring and ensuring compliance with the General Electricity Law, 

the National Energy Commission and the Superintendence of Electricity. The National Energy Commission is in 
charge of drafting and coordinating the legal framework and regulatory legislation, proposing and adopting policies 
and procedures to assure best practices, drafting plans to ensure the proper functioning and development of the 
energy sector and promoting investment. The Superintendence of Electricity's main responsibilities include 
monitoring and supervising compliance with legal provisions and rules, monitoring compliance with the technical 
procedures governing generation, transmission, distribution and commercialization of electricity and supervising 
electric market behavior in order to avoid monopolistic practices.

The electricity tariff applicable to regulated customers is subject to regulation within the concessions of the 

distribution companies. Clients with demand above 1 MW are classified as unregulated customers and their tariffs 
are unregulated.

Fuels and hydrocarbons are regulated by a specific law which establishes prices to end customers and a tax 

on consumption of fossil fuels. For natural gas there are regulations related to the procedures to be followed to 
grant licenses and concessions: i) distribution, including loading, transportation and compression plants; ii) the 
installation and operation of natural gas stations, including consumers and potential modifications of existing 
facilities; and iii) conversion equipment suppliers for vehicles. The regulation is administered by the Industrial and 
Commerce Ministry who supervises commercial and industrial activities in the Dominican Republic as well as the 
fuels and natural gas commercialization to the end users.

Key Financial Drivers — Financial results are likely to be driven by many factors including, but not limited to: 

•  Changes in spot prices due to fluctuations in commodity prices, (since fuel is a pass-through cost under the 

PPAs, any variation in oil prices will impact the spot sales for both Andres and Itabo) 

•  Contracting levels and the extent of capacity awarded

•  Supply shortages in the near term (next two to three years) may provide opportunities for short term upside, 

but new generation is expected to come online beginning 2018

•  Additional sales derived from domestic natural gas demand are expected to continue providing income and 

growth based on the entry of future projects and the fees from the infrastructure service.

In addition, the financial weakness of the three state-owned distribution companies due to low collection rates 

and high levels of non-technical losses has led to delays in payments for the electricity supplied by generators. At 
times when outstanding receivable balances have accumulated, AES Dominicana has accepted payment through 
other means, such as government bonds, in order to reduce the balance. There can be no guarantee that 
alternative collection methodologies will always be an avenue available for payment options. 

36

Construction and Development — DPP is converting its existing plant from open cycle to combined cycle. The 

project will recycle DPP's heat emissions and increase total power output by approximately 114 MW of gross 
capacity at an estimated cost of $260 million, fully financed with non-recourse debt. The EPC contract was signed 
on July 2, 2014, and the additional capacity is expected to become operational in the first half of 2017. Based on 
the increased capacity, AES Dominicana executed a PPA for 270 MW for a 6.5 year term beginning in 2017.

Panama

Business Description — AES owns and operates five hydroelectric plants and one thermoelectric power plant, 

Estrella del Mar I, which commenced operations in March 2015, representing 705 MW and 72 MW of hydro and 
thermal capacity respectively, for a total of 777 MW equivalent to 23% of the installed capacity in Panama. The 
majority of hydro sources in Panama are based on run-of-river technology, with the exception of the 260 MW 
Bayano plant. 

A portion of the PPAs with distribution companies will expire in December 2018 reducing the total contracted 
capacity of the company from 496 MW to 430 MW. Another portion contracted through Estrella del Mar I will expire 
in June 2020, reducing the total contracted capacity to 350 MW until December 2030.

Market Structure — Panama's current total installed capacity is 3,350 MW, of which 52% is hydroelectric, 8% 

wind, 2% solar and the remaining 38% thermal generation from diesel, bunker fuel and coal.

The Panamanian power sector is composed of three distinct operating business units: generation, distribution 

and transmission, all of which are governed by Electric Law 6 enacted in 1997. 

Generators can enter into long-term PPAs with distributors or unregulated consumers. In addition, generators 
can enter into alternative supply contracts with each other. Outside of the PPA market, generators may buy and sell 
energy in the short-term market. 

The National Dispatch Center implements the economic dispatch of electricity in the wholesale market. The 
National Dispatch Center's objectives are to minimize the total cost of generation and maintain the reliability and 
security of the electric power system, taking into account the price of water, which determines the dispatch of hydro 
plants with reservoirs. Short-term power prices are determined on an hourly basis by the last dispatched generating 
unit.

In Panama, dry hydrological conditions remained until June 2016, due to the presence of the El Niño 

phenomenon, affecting the generation output from hydroelectric facilities compared to the prior year. AES Panama 
had to purchase energy on the spot market to fulfill its contract obligations as its generation output was below 
contract levels. The drop in the commodities prices helped to reduce the replacement cost and the financial impact 
of spot purchases compared to the prior year. Despite the hydrology conditions, spot prices were down to $60/MWh 
from $91/MWh in 2015, limiting the amount recognized through the 2014-2016 Government Compensation 
Agreement to $1 million out of the possible $30 million for 2016. On March 31, 2014, the government of Panama 
agreed to reduce the financial impact of spot electricity purchases and transmission constraints equivalent to a 70 
MW reduction in contracted capacity for the period 2014-2016 by compensating AES Panama for spot purchases 
above the contracted price of $82.45/MWh, up to $40 million in 2014, $30 million in 2015 and $30 million in 2016.

Regulatory Framework — The SNE has the responsibilities of planning, supervising and controlling policies of 

the energy sector within Panama. With these responsibilities, the SNE proposes laws and regulations to the 
executive agencies that promote the procurement of electrical energy, hydrocarbons and alternative energy for the 
country.

The regulator of public services, known as the ASEP, is an autonomous agency of the government. ASEP is 

responsible for the control and oversight of public services including electricity and the transmission and distribution 
of natural gas utilities and the companies that provide such services.

Generators can only contract up to their firm capacity. Physical generation of energy is determined by the 

National Dispatch Center regardless of contractual arrangements.

Key Financial Drivers — Financial results are likely to be driven by many factors including, but not limited to: 

• 

In the event of low hydrology, high commodity prices will increase the business exposure and the cost of 
replacement power to fulfill our contractual commitments, partially mitigated by additional generation from 
Estrella del Mar I.

•  Fluctuations in commodity prices, mainly oil prices, affect the thermal generation cost impacting the spot 

prices and the opportunity cost of water.

37

•  Constraints imposed by the capacity of the transmission line connecting the west side of the country with the 
load center are expected to continue until the end of 2017 keeping surplus power trapped, particularly during 
the wet season. 

•  Country demand as GDP growth is expected to remain strong over the short and medium term.

Given that most of AES' portfolio is run-of-river, hydrological conditions have an important influence on its 
profitability. Variations in actual hydrology can result in excess or a short energy balance relative to our contract 
obligations. During the low inflow period of January through May, generation tends to be lower and AES Panama 
may purchase energy in the short-term market to cover contractual obligations. During the remainder of the year 
(June to December), generation tends to be higher and energy generated in excess of contract volumes is sold to 
the short-term market. In addition to hydrological conditions, commodity prices affect short-term electricity prices. 

Construction and Development — Continuing with the strategy to reduce reliance on hydrology started with 
the acquisition of the power barge, Estrella del Mar I, in August 2015 AES executed a partnership agreement with 
Deeplight Corporation, a minority partner, with the purpose to construct, operate and maintain a natural gas power 
generation plant and a liquefied natural gas terminal, in order to purchase and sell energy and capacity as well as 
commercialize natural gas and other ancillary activities related to natural gas. As of December 31, 2016, amounts 
capitalized include $254 million recorded in Construction in Progress and the project is scheduled to initiate 
operations in the first half of 2018.

Mexico

Business Description — AES has 1,055 MW of installed capacity in Mexico, including the 550 MW 

Termoeléctrica del Golfo ("TEG") and Termoeléctrica Peñoles ("TEP") facilities and Merida III ("Merida"), a 505 MW 
generation facility. 

The TEG and TEP pet coke-fired plants, located in San Luis Potosi, supply power to their offtakers under long-

term PPAs expiring in 2027 with a 90% availability guarantee. TEG and TEP secure their fuel under a long-term 
contract. 

Merida is a CCGT, located in Merida, on Mexico's Yucatan Peninsula. Merida sells power to the Federal 
Commission of Electricity ("CFE") under a capacity and energy based long-term PPA through 2025. Additionally, the 
plant purchases natural gas and diesel fuel under a long-term contract, the cost of which is then passed through to 
CFE under the terms of the PPA.

In line with AES' strategy of building strategic partnerships, on January 18, 2016 the 50/50 joint venture 

partnership agreement with Grupo BAL was fully executed. The joint venture will co-invest in power and related 
infrastructure projects in Mexico. 

Market Structure — Mexico has a single national electricity grid, the National Power System, covering nearly 

all of Mexico's territory. Mexico has an installed capacity totaling 68 GW with a generation mix of 72% thermal, 18% 
hydroelectric and 10% other. Electricity consumption is split between the following end users: industrial of 58%, 
residential of 26% and commercial and service of 16%.

Regulatory Framework — Following the constitutional changes approved in December 2013, during 2014 and 

2015 the Mexican government issued a package of secondary regulations, including the Electricity Law, and 
operational dispositions, with the objective to start the implementation of a new regulatory framework with the 
following characteristics:

•  The energy market liberalization in January 2016 through the implementation of: wholesale electricity market 

(day ahead and real time market), ancillary services, capacity, Clean Energy Certificates, and Financial 
Transmission Rights market.

•  CFE's, former state-owned electric monopoly, vertical and horizontal disintegration into different segments of the 

value chain: generation, transmission, distribution and commercialization. 

•  CENACE as new ISO is responsible for managing the wholesale electricity market, transmission and distribution 

infrastructure, planning the network developments, guaranteeing open access to network infrastructure, 
executing competitive mechanisms to cover regulated demand, and setting transmission charges.
Implementation of annual mid and long term auctions to secure supply for the regulated demand, establishing a 
PPA with CFE as the Basic Supplier.

• 

According to the new regulatory framework, new assets developed under the new framework or assets 
transferred to the new regime and in operation after the approval of the Electricity Law (August 2014) are eligible to 
participate in the new markets. Additionally, projects developed and operated under the Electric Public Service Law 

38

(self-supply framework) like TEG/TEP, could choose to participate. Until the new framework is further analyzed, 
AES will continue operating under the same conditions. Merida III and TEG/TEP will continue providing power 
under long-term contracts and selling any excess or surplus energy produced to CFE.

Key Financial Drivers — Financial results are likely to be driven by many factors including, but not limited to:

•  Operational performance (as the companies are fully contracted and better performance provides additional 
financial benefits including performance incentives and/or excess energy sales (in the case of TEG/TEP). 

•  The energy prices of TEG/TEP for the sales in excess over its long-term contracts are driven by the average 

• 

production cost of CFE which is highly dependent on natural gas and oil. 
If the average production cost of CFE is higher than the cost of generating with pet coke, our businesses in 
Mexico will benefit provided that they are able to sell energy in excess of their PPAs.

Puerto Rico

Business Description — AES Puerto Rico owns and operates a coal-fired cogeneration plant and a solar plant 

of 524 MW and 24 MW, respectively, representing approximately 9% of the installed capacity in Puerto Rico. Both 
plants have long-term PPAs expiring in 2027 and 2032, respectively, with PREPA, a state-owned entity that supplies 
virtually all of the electric power consumed in Puerto Rico and generates, transmits and distributes electricity to 
1.5 million customers. See Item 7.—Key Trends and Uncertainties—Macroeconomic and Political—Puerto Rico for 
further discussion of the long-term PPA with PREPA.

El Salvador

Business Description — AES El Salvador also owns AES Nejapa, a 6 MW power plant generating electricity 

with methane gas from a landfill, fully contracted with CAESS. During 2015, AES El Salvador began operations of a 
AES Moncagua, a 2.5 MW solar facility located in the East of the country, which is fully contracted with EEO.

The sector is governed by the General Electricity Law and the general and specific orders are issued by 
Superintendencia General de Electricidad y Telecomunicacions ("SIGET"). SIGET, jointly with the distribution 
companies in El Salvador, completed the tariff reset process in December 2012 and defined the tariff calculation to 
be applicable for the five year period 2013-2017.

Europe Businesses 

Bulgaria

Business Description — Our Maritza plant is a 690 MW lignite fuel plant that was commissioned in June 2011. 
Maritza is fully compliant with the European Union Industrial Emission Directive, which became effective in January 
2016. Maritza's entire power output is contracted with NEK under a 15-year PPA, capacity and energy based, with a 
fuel pass-though, expiring in 2026. The lignite and limestone are supplied under 15-year fuel supply contracts.

AES also owns an 89% economic interest in the St. Nikola wind farm with 156 MW of installed capacity. St. 

Nikola was commissioned in March 2010. Its entire power output is contracted with NEK under a 15-year PPA 
expiring in March 2025.

Market Structure — The maximum market capacity in 2016 was approximately 13 GW. Thermal generation, 

which is mostly coal-fired, and nuclear power plants account for 61% of the installed capacity.

Regulatory Framework — The electricity sector in Bulgaria operates under the Energy Act of 2004 which 
allows the sale of electricity to take place freely at negotiated prices, at regulated prices between parties or on the 
organized market. In 2016 the government of Bulgaria made advances toward market liberalization and has 
engaged with the World Bank to develop a model for a fully liberalized electricity market in Bulgaria. The final report 
with recommendations from the World Bank was finalized in December 2016. The Independent Bulgarian Energy 
Exchange (IBEX) started commercial operation of the power exchange in January 2016 with the introduction of Day 
Ahead market platform. In September 2016, IBEX expanded its trading platform for bilateral forward contracts. The 
next step of the development of IBEX is the introduction of intra-day trading, which is expected in mid-2017.

Our investments in Bulgaria rely on long-term PPAs with NEK, the state-owned electricity public supplier and 

energy trading company. NEK had been facing some liquidity issues and had been delayed in making payments 
under the PPAs with Maritza and St. Nikola. In August 2015, the ninth amendment of Maritza's PPA was executed, 
under which Maritza and NEK agreed to reduce the capacity payment to Maritza by 14% through the PPA term 
without impacting the energy price component. In exchange, NEK paid Maritza its overdue receivables. The 
amendment became effective in April 2016 upon full payment of the overdue receivables by NEK. Maritza has 
experienced timely collection of outstanding receivables from NEK since May 2016.

The Directorate-General for Competition of the European Commission (“DG Comp”) continues to review NEK’s 

respective PPAs with Maritza and an unrelated generator pursuant to the European Commission’s state aid rules. 
Although no formal investigation has been launched by DG Comp, Maritza has met with the DG Comp case team 
and representatives of Bulgaria to discuss the agency’s review. Maritza expects that the parties will engage in 

40

further discussions on the issues surrounding the review. At this time, we cannot predict the outcome of such 
discussions, nor can we predict how DG Comp might resolve its review if the anticipated discussions fail to result in 
an agreement concerning the review. Maritza believes that its PPA is legal and in compliance with all applicable 
laws, and it will take all actions necessary to protect its interests, whether through negotiated agreement or 
otherwise. However, there can be no assurances that this matter will be resolved favorably; if it is not, there could 
be a material adverse impact on Maritza’s and the Company’s respective financial statements.

In 2015, a number of measures were introduced to the regulation of the energy sector that significantly 
improved the liquidity of NEK. As a result, NEK is forecast to end the year 2016 with a $7 million net profit, more 
than a $102 million improvement over year 2015 and more than a $316 million improvement over year 2014. 
However, the financial situation of NEK remains subject to political conditions and regulatory changes in Bulgaria.

Key Financial Drivers — Both businesses, Maritza and St. Nikola, operate under PPA contracts. For the 

duration of the PPA, the financial results are primarily driven by, but not limited to: 

• 

the availability of the operating units

the level of wind resource for St. Nikola 

• 
•  NEK's ability to meet the terms of the PPA contract

United Kingdom

Business Description — AES' generation businesses in the United Kingdom are located in Northern Ireland 

and operate in the Irish SEM (1,726 MW). The Northern Ireland generation facilities consist of two plants within the 
Greater Belfast region. Our Kilroot plant is a 701 MW coal-fired plant with an additional 10 MW of energy storage 
facility and our Ballylumford plant is a 1,015 MW gas-fired plant. These plants provide approximately 62% of the 
Northern Ireland installed capacity and 16% of the combined installed capacity for the island of Ireland.

Kilroot is a merchant plant that bids into the SEM. the plant earns margin when scheduled in merit, out of 

merit, for capacity payments, and for ancillary services. Out of merit dispatch, through which costs are recovered, 
occurs when there are system constraints related to wind generation, voltage and transmission.

Ballylumford is partially contracted for 600 MW under a PPA with PPB that expires in 2023 with the remaining 

capacity bid into the SEM market. 310 MW of this merchant capacity has a supplemental Local Reserve Services 
Agreement ("LRSA") with the system operator. Ballylumford earns margin from availability payments received under 
the PPA, capacity payments offered through the SEM and revenues from the LRSA. Additionally, Ballylumford 
receives margin from out of merit dispatch through which the costs of operation are recovered as well as ancillary 
services.

Market Structure — The majority of the generation capacity in the SEM is represented by gas-fired power 
plants, which results in market sensitivity to gas prices. Wind generation capacity represents approximately 25% of 
the total generation capacity. The governments of Northern Ireland and the Republic of Ireland plan further 
increases in renewable energy sources. Market availability and liquidity of hedging products are weak, reflecting the 
limited size and immaturity of the market, the predominance of vertical integration and lack of forward pricing. There 
are essentially three products (baseload, mid-merit and peaking) which are traded between the generators and 
suppliers.

Regulatory Framework — The SEM is an energy market established in 2007 and is based on a gross 
mandatory pool within which all generators with a capacity higher than 10 MW must trade the physical delivery of 
power. Generators are centrally dispatched based on merit order and physical constraints of the system. The SEM 
structure is under review by the regulatory authorities with a new structure due to be introduced in the second 
quarter of 2018.

In addition, there is a capacity payment mechanism to ensure that sufficient generating capacity is offered to 

the market. The capacity payment is derived from a regulated Euro-based capacity payment pool, established a 
year ahead by the regulatory authority. Capacity payments are based on the declared availability of a unit and have 
a degree of volatility to reflect seasonal influences, demand and the actual out-turn of generation declared available 
over each trading period.

Environmental Regulation — In 2011, the European Commission adopted the Industrial Emission Directive 
("IED") that establishes the Emission Limit Values ("ELV") for SO2, NOx and dust emissions effective January 1, 
2016. Both Ballylumford and Kilroot are required to comply with the IED. The Ballylumford C Station is compliant 
without the need for investment. Both Ballylumford B Station and Kilroot required investment to be in compliance.

41

The IED provides for two options that may be implemented by the European Union member states other than 

compliance with the new ELV's the Transitional National Plan or Limited Life Time Derogation.

Kilroot has opted into the Transitional National Plan which allows the plant to operate between 2016-2020, 

being exempt from compliance with ELVs, but observing a ceiling set for maximum annual emissions that is based 
on the last 10 years average emissions and operating hours. Kilroot has invested approximately $10 million in 
Umbrella Selective Non Catalytic Reduction technology, which reduces the plant's NOx emissions enabling the plant 
to increase its capacity factor within the ceiling of NOx emissions and earn energy margin. The Transitional National 
Plan also established a UK wide NOx trading scheme which Kilroot avails of as required. Further technical 
modifications are being evaluated which could make the plant fully compliant with the IED from 2020.

Without investment, the Ballylumford B station of 540 MW did not meet the standards of the IED. In 2014, AES 

secured a LRSA with the Transmission System Operator ("TSO") to refurbish two of the three units to be compliant 
with ELVs under IED, providing at least 250 MW of capacity from 2016 to 2018 with an option to extend to 2020 by 
the TSO. The project was executed in 2015 with an achieved combined gross output of 310 MW.

Key Financial Drivers — For our businesses in the SEM market, the financial results will be driven by, but not 

limited to, the following:

•  Regulatory changes to the market structure and payment mechanism

•  Availability of the operating units
•  Commodity prices (gas, coal and CO2) and sufficient market liquidity to hedge prices in the short-term
•  Electricity demand in the SEM (including impact of wind generation)

Kazakhstan

Business Description — Our businesses account for approximately 6% of the total annual generation in 
Kazakhstan. Of the total capacity of 2,776 MW, 1,033 MW is hydroelectric and operates under a concession 
agreement until the beginning of October 2017 and 1,743 MW is coal-fired capacity which is owned outright. The 
thermal plants are designed to produce heat with electricity as a co- or by-product.

The Kazakhstan businesses act as merchant plants for electricity sales by entering into bilateral contracts 

directly with consumers for periods of generally no more than one year. There are limited opportunities for the 
plants to be in contracted status, as there is no central offtaker, and the few businesses that could take a whole 
plant's generation tend to have in-house generation capacity.

The hydroelectric plants are run-of-river and rely on river flow and precipitation, particularly snow. Due to the 

presence of a large multi-year storage dam upstream and a season minimum river flow rate agreement with Russia 
downstream, the plants are protected against significant downside risk to their volume in years with low 
precipitation. AES does not control water flow which impacts our generation.

Ust Kamenogorsk CHP provides heat to the city of Ust Kamenogorsk through the city heat network company 

(Ust Kamenogorsk Heat Nets). Ust Kamenogorsk CHP is their only source of supply.

Market Structure — The Kazakhstan electricity market totals approximately 21,307 MW, of which 17,504 MW 

is available. The bulk of the generating capacity in Kazakhstan is thermal with coal as the main fuel. As coal is 
abundantly available in Kazakhstan, most plants are designed to burn local coal. The geographical remoteness of 
Kazakhstan, in combination with its abundant resources, results in coal prices that are not reflective of world coal 
prices, current delivered cost is less than $12 per metric ton. In addition, the government closely monitors coal 
prices, due to their impact on the price of socially necessary heating and on electricity tariffs.

Regulatory Framework — All Kazakhstan generating companies sell electricity at or below their respective 

tariff-cap level. These tariff-cap levels have been fixed by the Kazakhstan government for the period 2009-2018 for 
each of the fifteen groups of generators. These groups were determined by the Ministry of Energy, based on a 
number of factors including plant type and fuel used.

In July 2012, Kazakhstan enacted an amendment to its Electricity Law requiring electricity producers to 

reinvest all profits generated during the years 2013-2015 as part of annual investment obligation agreements, 
thereby limiting the businesses ability to distribute dividends. These investment obligation agreements had to be 
equal to the sum of the planned annual depreciation and profit. Selection of investment projects was at the 
discretion of electricity producers, but the Ministry of Energy had the right to reject submitted proposals. An 
electricity producer without an investment obligation agreement executed by the Ministry of Energy was not allowed 
to charge tariffs exceeding its incremental cost of production, excluding depreciation. 

42

In November 2015, Kazakhstan enacted amendments to its Electricity Law to eliminate the obligation for 
power plants to sign annual investment obligation agreements for 2016-2018, thereby allowing the businesses to 
distribute dividends. In addition, the amendment stated that a centrally organized capacity market will be 
established by 2019 and that the Kazakhstan government plans to prolong price cap regulation by fixing new caps 
on energy and capacity tariffs for each group of power plants.

Kazakhstan government has approved a renewable energy law which set feed-in tariffs for renewable energy 

and set a renewable energy target of 3% by 2020 and 10% by 2030. This renewable energy law imposes an 
obligation on all non-renewable power plants to purchase renewable energy at the renewable energy tariff and 
resell it to customers at their own, lower price cap level. 

Heat production in Kazakhstan is also regulated as a natural monopoly. The heat tariffs are set on a cost-plus 
basis by making an application to the Committee of Natural Monopoly Regulation and Competition Protection, the 
regulator. Currently, tariffs are only for multi-year periods, but with some annual adjustments for fuel cost.

Key Financial Drivers — The financial results for assets in Kazakhstan are driven by many factors including, 

but not limited to: 

•  Availability of the operating units; 

•  Regulated electricity tariff-cap levels and heat tariff levels
•  Weather conditions,
•  Regulatory changes to the market structure and payment mechanism 
•  Cost of coal and Kazakhstan currency exchange rate fluctuation.

Jordan

Business Description — In Jordan, AES has a 37% controlling interest in Amman East, a 381 MW oil/gas-fired 
plant fully contracted with the national utility under a 25-year PPA and a 36% controlling interest in the IPP4 plant in 
Jordan, a 250 MW oil/gas-fired peaker plant which commenced operations in July 2014, fully contracted with the 
national utility under a 25-year PPA. As we have controlling interest in these businesses, we consolidate the results 
in our operations.

Asia Businesses

India

Business Description — OPGC is a 420 MW coal-fired generation facility located in the state of Odisha. OPGC 

has a 30-year PPA with GRIDCO Limited, a state utility, expiring in 2026. The PPA is composed of a capacity 
payment based on fixed parameters and a variable component, including a pass-through of actual fuel costs. OPGC 
is an unconsolidated entity and results are reported as Net Equity in Earnings of Affiliates in our Consolidated 
Statements of Operations.

Environmental Regulation — The Ministry of Environment, Forest and Climate Change in India has recently 

amended the Environment (Protection) Rules with stricter emission limits for new and existing thermal power plants 
via their notification issued in December 2015. All existing plants installed before December 31, 2003 are required 
to meet revised emission limits within two years and any new thermal power plants that will be operational from 
January 1, 2017 are required to operate with the revised emission limits. An FGD system needs to be installed in 
the existing units of OPGC for complying with SO2 emissions requirements. The business has evaluated the options 
and the cost implications for the operating plant including design modification and schedule implications for the 
expansion project. The larger impact of these amendments and requirements of substantial investments to meet the 
revised environmental guidelines across the power sector in India, borne by the public and private power generation 
companies, is still under review. We believe the cost of complying with the new environmental regulations will be a 
pass-through in the GRIDCO tariff for both existing and expansion units. Ministry of Power has issued a revised 
Tariff Policy in January 2016 to bring more regulatory certainty, attract private investment, ensure distribution 
efficiency and promote renewable energy.

Construction and Development — As noted above, AES has one coal-fired project under development with a 
total capacity of 1,320 MW which is an expansion of our existing OPGC business. The project started construction 
in April 2014 and is currently expected to begin operations in the second half of 2018. As of December 31, 2016, 
total capitalized costs at the project level were $598 million (the Company's share is $293 million as part of our 
investment in subsidiary). In addition, AES has capitalized $18 million in construction management costs which are 
not attributable to the partner. Currently, 50% of the expansion capacity is contracted with the state offtaker, 
GRIDCO, for a period of 25 years, with a normative after-tax rate of return of 15.5% with an opportunity to capture 
additional 0.5% tied to timely completion of the project. The rest of the 50% of the generation capacity is proposed 
to be offered to GRIDCO under a fresh regulated PPA due to restrictions on power sale under new guidelines.

In August 2014, the Supreme Court of India invalidated the allocation of captive coal blocks. The government 

of India has subsequently enacted new laws allowing coal block allocation to companies with limited levels of 
private ownership, based on which the coal blocks have been allocated to a subsidiary of OPGC, Odisha Coal and 
Power Ltd., which is an OPGC joint venture with another company wholly-owned by the government of Odisha. This 
new company meets the lower private ownership stipulations for allocation of mines. 

44

Key Financial Drivers — Financial results are likely to be driven by many factors including, but not limited to: 

•  Operating performance of the facility

•  Regulatory and environmental policy changes

Philippines 

Business Description — The Masinloc power project in the Philippines is a 630 MW gross coal-fired plant 

located in Zambales, Philippines and is interconnected to the Luzon Grid, and is owned 51% by AES. More than 
95% of Masinloc's current peak capacity is contracted through medium to long-term bilateral contracts primarily with 
Meralco, the largest distribution company in the Philippines, several electric cooperatives and industrial customers.

In January 2013, Masinloc entered into a new PSA with its main customer, Meralco, as the previous PSA 
expired in December 2012. The PSA is for seven years and included an additional three-year extension option, 
which the parties agreed to exercise in March 2016. Payments are primarily capacity-based. The PSA is primarily 
priced in U.S. dollars, aligning the revenues with the majority of variable and fixed costs (fuel, debt, insurance) and 
minimizing currency exchange risks. Masinloc's remaining contracts on the existing units expire between 2017 and 
2026.

Market Structure — The Philippine power market is divided into three grids representing the country's three 
major island groups — Luzon, Visayas and Mindanao. Luzon, which includes Manila and is the country's largest 
island, has limited interconnection with Visayas and represents 85% of the total demand of both regions. Luzon and 
Visayas together have an installed capacity of 17,294 MW.

There is diversity in the mix of the Luzon — Visayas generation. For Luzon, coal accounts for 49% of 

generation, followed by natural gas at 32%, and the remaining 19% is comprised by oil, geothermal, and renewable 
resources (i.e. hydro, solar, and wind, with the latter two having priority dispatch with feed-in tariff). For Visayas, 
geothermal is the top energy source and accounts for 47% of generation followed by coal at 39%, and the 
remaining 14% comprised by oil, geothermal, and renewable resources.

The primary customers for electricity are private distribution utilities, electric cooperatives, and large 

contestable (industrial and commercial) customers. Over 90% of the system's total energy requirement is currently 
being sold/purchased through medium (three to five years) to long (six to ten years) term bilateral contracts. The 
remaining energy is sold through the Wholesale Electricity Spot Market ("WESM"), which is the real-time, bid-based 
and hourly market for energy where the sellers and the buyers adjust their differences between their production/
demand and their contractual commitments.

Regulatory Framework — The Philippines has divided its power sector into generation, transmission, 
distribution and supply under the Electric Power Industry Reform Act of 2001. This Act primarily aims to increase 
private sector participation in the power sector and to privatize the Philippine government's generation and 
transmission assets. Generation and supply are open and competitive sectors, while transmission and distribution 
are regulated sectors. Sale of power is conducted primarily through medium or long-term bilateral contracts 
between generation companies and distribution utilities specifying the volume, price and conditions for the sale of 
energy and capacity, which are approved by the ERC. Power is traded in the WESM which operates under a gross 
pool, central dispatch and net settlement protocols. Parties to bilateral contracts settle their transactions outside of 
the WESM and distribution companies or electricity cooperatives buy their imbalance (i.e., power requirements not 
covered by bilateral contracts) from the WESM. Distribution utilities and electric cooperatives are allowed to pass on 
to their end-users the bilateral contract rates, including WESM purchases, approved by the ERC.

Other Regulatory Considerations — Pursuant to Electric Power Industry Reform Act of 2001, Retail 

Competition & Open Access ("RCOA") commenced on June 26, 2013, under which retail electricity suppliers, who 
are duly licensed by the ERC, may supply directly to contestable customers (end-users with an average demand of 
at least 1 MW), with distribution companies or electricity cooperatives providing non-discriminatory wire services. In 
order to ensure implementation of RCOA and stimulate transition of contestable customers, ERC issued rules 
implementing mandatory contestability. Under the said rules, all contestable customers are mandated to enter into 
power supply contracts with retail electricity suppliers by February 2017 instead of purchasing power from their local 
distribution utility. 

Masinloc has obtained a retail electricity supplier license from the ERC and currently markets power to 
contestable customers. Unlike Masinloc’s contracts with distribution utilities, its contract with contestable customers 
do not require ERC approval to be implemented. 

Environmental Regulation — To promote renewable energy, the Philippine government enacted the 

Renewable Energy Act of 2008 which provides incentives for the development, utilization and commercialization of 

45

renewable energy resources such as solar, wind, small hydroelectric and biomass energies. In addition, the 
government also adopted a feed-in tariff scheme which was detailed under ERC Res No.16 s. 2010, where an 
eligible producer of renewable energy is entitled to a guaranteed payment of a fixed rate feed-in tariff for each 
kilowatt-hour of energy it supplies to the grid. The feed-in tariff to be approved shall be specific for each emerging 
renewable energy technology and shall be extended on a first-to-build basis as there is an established cap per 
technology on eligibility under the feed-in tariff scheme. 

Other Environmental Regulation — Over the past year, the government of the Philippines has sought to 
reduce its environmental impact, including the country’s carbon footprint. As such, the Department of Environment 
and Natural Resources is promoting stricter environmental compliance, particularly on the effluent discharge 
standards. The new effluent standards issued in May 2016 have restricted discharge temperature limit compared to 
previous standards. It is yet uncertain if the new standards will be applicable to the projects under construction 
which received environmental clearance before the new standards were issued.

Construction and Development — AES started construction on a 335 MW gross Masinloc expansion project in 

March 2016. The total capitalized cost at December 31, 2016 is $133 million. An engineering, procurement and 
construction contract was entered into with POSCO Engineering and Construction of Korea and their wholly owned 
Philippine affiliate company, Ventanas Philippine Construction Incorporated, in December 2015, with full notice to 
proceed issued on March 2016. The project is expected to be commercially operating in 2019. Progress is 
advancing as planned and the project is expected to be completed on schedule and within budget. The additional 
capacity is targeted for sale to distribution utilities, electric cooperatives, and industrial and commercial customers in 
the Luzon and Visayas grids. Approximately 50% of this additional capacity has already been contracted with an 
expectation to have additional capacity contracted by the date of commercial operations.

Key Financial Drivers — Financial results are likely to be driven by many factors including, but not limited to: 

•  Operating performance of the facility
•  Demand from contracted customers 
•  Whole sale electricity price in the market

Vietnam

Business Description — The Mong Duong II power project is a 1,242 MW gross coal-fired plant located in 
Quang Ninh Province of Vietnam and was constructed under a BOT contract (the project will be transferred to 
Vietnamese government after 25 years). AES-VCM Mong Duong Power Company Limited ("the BOT Company") is 
a limited liability joint venture owned by affiliates of AES (51%), Posco Energy Corporation (30%) and China 
Investment Corporation (19%). This is the first and largest coal-fired BOT project using pulverized coal fired boiler 
technology in Vietnam. The BOT Company has entered a PPA with EVN, the national utility, and a Coal Supply 
Agreement with Vinacomin, a state owned entity, both with a 25 year term starting from Commercial Operation 
Date.

Since April 22, 2015, both units of the power facility have been in commercial operations, six months earlier 

than the committed schedule with the Vietnamese government. The BOT Company makes available the 
dependable capacity and delivers electrical energy to EVN and, in return, EVN makes payments to the BOT 
Company.

Market Structure — The Vietnam power market is divided into three regions (North, Central and South), with 
total installed capacity of approximately 41GW, an 8% increase from 2015 (38GW). The total demand in 2016 was 
159.5 billion kWh with the highest demand of 76.7 billion kWh in the South and 66.5 billion kWh in the North.

The fuel mix in Vietnam is comprised of hydropower 35% (priority dispatch with low tariff), coal 36%, gas 19%, 
diesel and small hydro generation 4%, oil 2% (dispatched during emergencies or during peak demand), thermo-gas 
1% and the remaining 3% imported from China and Lao. The government has a plan to increase thermal power 
capacity, primarily with coal, to reduce the dependence on hydroelectricity. According to the Master Plan VII revised 
in March 2016, the total targeted installed capacity for 2020 is approximately 60,000 MW, in which coal-fired power 
will account for 43%, hydropower and pumped storage hydropower 30%, gas-fired thermo-power 15%, renewable 
energy 10%, and imported power 2%.

EVN owns 57% of installed generation capacity followed by Petro Vietnam 11%, Vinacomin 4%, BOT projects 
11% and others 17%. EVN is a state-owned company that is solely in charge of buying and selling electricity all over 
Vietnam. The government is planning to decrease EVN's ownership and increase private sector participation in the 
power market. 

46

Regulatory Framework — The electricity sector is overseen by several key government entities, including the 
National Assembly, the Prime Minister, the Ministry of Industry and Trade and the Electricity Regulatory Agency of 
Vietnam, which is under the supervision of the Ministry of Industry and Trade. These entities are responsible for the 
issuance of laws, guidance, and implementing regulations for the sector. The Ministry of Industry and Trade, in 
particular, is responsible for formulating a program to restructure the power industry, develop the electricity market 
and promulgating electricity market regulations. The fuel supply is owned by the government through Vinacomin 
and Petro Vietnam. The government plans to equitize EVN-owned generation companies and separate generation, 
System and Market Provider and distribution into three different independent operations in order to establish the 
competitive power market.

Other Regulatory Considerations — According to Decision 63/2013/QD-TTG dated August 2013, the roadmap 

of the power market of Vietnam consists of three phases. The first phase established a competitive electricity 
market and was finished at the end of 2014. The second phase: (i) period of 2015-2016 for establishment of a pilot 
competitive wholesale electricity market; and (ii) period of 2017-2021 for implementation of a competitive wholesale 
electricity market. The third phase: (i) period of 2022-2023 for establishment of a pilot competitive retail electricity 
market; and (ii) from 2024 onward for implementation of competitive retail electricity market. EVN, a long standing 
monopoly in the whole chain of generation, transmission and distribution, is being restructured to allow spin-off of 
several subsidiaries into either independent state-owned enterprises or joint stock companies. The BOT power 
plants will not participate in the power market; alternatively the single buyer will bid the tariff on the power pool on 
their behalf.

Environmental Regulation — Mong Duong II BOT Power Plant complies strictly with environmental 

requirements involving local regulations and IFC Environmental, Health and Safety Guidelines for thermal power 
plants. 

Key Financial Drivers — Financial results are likely to be driven by many factors including, but not limited to 

the operating performance of the facility.

concern about greenhouse gas, or GHG, emissions and the potential risks associated with climate change and are 
taking actions which could have a material adverse impact on our consolidated results of operations, financial 
condition and cash flows in this Form 10-K. For a discussion of the laws and regulations of individual countries 
within each SBU where our subsidiaries operate, see discussion within Item 1.—Business of this Form 10-K under 
the applicable SBUs.

Many of the countries in which the Company does business also have laws and regulations relating to the 
siting, construction, permitting, ownership, operation, modification, repair and decommissioning of, and power sales 
from, electric power generation or distribution assets. In addition, international projects funded by the International 
Finance Corporation, the private sector lending arm of the World Bank, or many other international lenders are 
subject to World Bank environmental standards or similar standards, which tend to be more stringent than local 
country standards. The Company often has used advanced generation technologies in order to minimize 
environmental impacts, such as CFB boilers and advanced gas turbines, and environmental control devices such 
as flue gas desulphurization for SO2 emissions and selective catalytic reduction for NOx emissions.

Environmental laws and regulations affecting electric power generation and distribution facilities are complex, 
change frequently and have become more stringent over time. The Company has incurred and will continue to incur 
capital costs and other expenditures to comply with these environmental laws and regulations. See Item 7.—
Management's Discussion and Analysis of Financial Condition and Results of Operations—Environmental Capital 
Expenditures in this Form 10-K for more detail. The Company and its subsidiaries may be required to make 
significant capital or other expenditures to comply with these regulations. There can be no assurance that the 
businesses operated by the subsidiaries of the Company will be able to recover any of these compliance costs from 
their counterparties or customers such that the Company's consolidated results of operations, financial condition 
and cash flows would not be materially affected.

Various licenses, permits and approvals are required for our operations. Failure to comply with permits or 
approvals, or with environmental laws, can result in fines, penalties, capital expenditures, interruptions or changes 
to our operations. Certain subsidiaries of the Company are subject to litigation or regulatory action relating to 
environmental permits or approvals. See Item 3.—Legal Proceedings in this Form 10-K for more detail with respect 
to environmental litigation and regulatory action.

United States Environmental and Land-Use Legislation and Regulations

In the U.S. the CAA and various state laws and regulations regulate emissions of air pollutants, including SO2, 

NOX, PM, GHGs, mercury and other hazardous air pollutants. Certain applicable rules are discussed in further 
detail below.

CSAPR — CSAPR addresses the "good neighbor" provision of the CAA, which prohibits sources within each 

state from emitting any air pollutant in an amount which will contribute significantly to any other state’s 
nonattainment, or interference with maintenance of, any NAAQS. The CSAPR requires significant reductions in SO2 
and NOX emissions from power plants in many states in which subsidiaries of the Company operate. Once fully 
implemented, the rule requires SO2 emission reductions of 73%, and NOX reductions of 54%, from 2005 levels. The 
CSAPR is implemented, in part, through a market-based program under which compliance may be achievable 
through the acquisition and use of emissions allowances created by the EPA. The CSAPR contemplates limited 
interstate and unlimited intra-state trading of emissions allowances by covered sources. Initially, the EPA issued 

48

emissions allowances to affected power plants based on state emissions budgets established by the EPA under the 
CSAPR. The Company is required to comply with the CSAPR in several states, including Ohio, Indiana, Oklahoma 
and Maryland. The Company complies with CSAPR through operation of existing controls and purchases of 
allowances on the open market, as needed. While the Company's 2015 CSAPR compliance costs were immaterial, 
the future availability of and cost to purchase allowances to meet the emission reduction requirements is uncertain 
at this time.

The EPA issued an interim final rule establishing the following deadlines for implementation of the CSAPR:

•  January 1, 2015: Phase 1 (2015 and 2016) began for annual trading programs. Existing units must have begun 

monitoring and reporting SO2 and NOx emissions.

•  May 1, 2015: Phase 1 began for ozone-season NOx trading program. Existing units must have begun monitoring 

and reporting NOx emissions.

•  December 1, 2015 (and each Dec. 1 thereafter): Date by which sources must demonstrate compliance with 

ozone-season NOx trading program (i.e., allowance transfer deadline).

•  March 1, 2016 (and each March 1 thereafter): Date by which sources must demonstrate compliance with annual 

trading programs (i.e., allowance transfer deadline).

•  January 1, 2017: Phase 2 (2017 and beyond) begins for annual trading programs. Assurance provisions in 

effect.

•  May 1, 2017: Phase 2 (2017 and beyond) begins for ozone-season NOx trading program. Assurance provisions 

in effect. 

 On October 26, 2016, the EPA published a final rule to update the CSAPR to address the 2008 ozone NAAQS 
("CSAPR Update Rule"). The CSAPR Update Rule finds that NOx ozone season emissions in 22 states (including 
Indiana, Maryland, Ohio and Oklahoma) affect the ability of downwind states to attain and maintain the 2008 ozone 
NAAQS, and, accordingly, the EPA issued federal implementation plans that both updated existing CSAPR NOx ozone 
season emission budgets for electric generating units within these states and implemented these budgets through 
modifications to the CSAPR NOx ozone season allowance trading program. Implementation will start in the 2017 ozone 
season (May-September 2017). Affected facilities will receive fewer ozone season NOx allowances in 2017 and later, 
resulting in the need to purchase additional allowances. At this time, we cannot predict what the impact will be with 
respect to these new standards and requirements, but it could be material if certain facilities will need to purchase 
additional allowances based on reduced allocations.

MATS — Pursuant to Section 112 of the CAA, the EPA published a final rule in 2012 called the MATS 

establishing National Emissions Standards for Hazardous Air Pollutants from coal and oil-fired electric utility steam 
generating units. The rule required all affected power plants to comply with the applicable MATS standards by April 
2015, with the possibility of obtaining a one year extension, if needed, to complete the installation of necessary 
controls. All of the Company's U.S. coal-fired plants operated by the Company's subsidiaries are currently in 
compliance with MATS.

There currently are challenges to the EPA’s determination that it was appropriate and necessary to regulate 
hazardous air pollutant emissions from electric generating units - the basis for the MATS rule - proceeding in the 
United States Court of Appeals for the District of Columbia Circuit (the “D.C. Circuit”) but, in the meantime, the 
MATS rule remains in effect. We currently cannot predict the outcome of this litigation, or its impact, if any, on our 
MATS compliance or ultimate costs.

New Source Review ("NSR") — The NSR requirements under the CAA impose certain requirements on major 

emission sources, such as electric generating stations, if changes are made to the sources that result in a 
significant increase in air emissions. Certain projects, including power plant modifications, are excluded from these 
NSR requirements, if they meet the RMRR exclusion of the CAA. There is ongoing uncertainty, and significant 
litigation, regarding which projects fall within the RMRR exclusion. The EPA has pursued a coordinated compliance 
and enforcement strategy to address NSR compliance issues at the nation's coal-fired power plants. The strategy 
has included both the filing of suits against power plant owners and the issuance of NOVs to a number of power 
plant owners alleging NSR violations. See Item 3.—Legal Proceedings in this Form 10-K for more detail with 
respect to environmental litigation and regulatory action, including a NOV issued by the EPA against IPL concerning 
NSR and prevention of significant deterioration issues under the CAA. 

In 2000, DP&L's Stuart Station received a NOV from the EPA alleging that certain activities undertaken in the 

past are outside the scope of the RMRR exclusion. Hutchings Station also received such a NOV in 2009. 
Additionally, generation units partially owned by DP&L but operated by other utilities have received such NOVs 

49

relating to equipment repairs or replacements alleged to be outside the RMRR exclusion. The NOVs issued to 
DP&L-operated plants have not been pursued through litigation by the EPA.

If NSR requirements were imposed on any of the power plants owned by the Company's subsidiaries, the 

results could have a material adverse impact on the Company's business, financial condition and results of 
operations. In connection with the imposition of any such NSR requirements on IPL, the utility would seek recovery 
of any operating or capital expenditures related to air pollution control technology to reduce regulated air emissions, 
but not fines or penalties; however, there can be no assurances that they would be successful in that regard.

Regional Haze Rule — The EPA's "Regional Haze Rule" is intended to reduce haze and protect visibility in 

designated federal areas, and sets guidelines for determining BART at affected plants and how to demonstrate 
"reasonable progress" towards eliminating man-made haze by 2064. The Regional Haze Rule required states to 
consider five factors when establishing BART for sources, including the availability of emission controls, the cost of 
the controls and the effect of reducing emission on visibility in Class I areas (including wilderness areas, national 
parks and similar areas). The statute requires compliance within five years after the EPA approves the relevant SIP 
or issues a federal implementation plan, although individual states may impose more stringent compliance 
schedules. 

EPA previously determined that states included in the CSAPR would not be required to make source-specific 
BART determinations for BART-affected electric generating units, reasoning that the emissions reductions required 
by the CSAPR were "better than BART." Concurrently, EPA also finalized a limited disapproval of certain states' 
plans — including Ohio's — that previously relied on the EPA's Clean Air Interstate Rule to improve visibility and 
substituted a Federal Implementation Plan that relies on the CSAPR. Environmental groups have challenged EPA's 
determination than the CSAPR is "better than BART." The challenge currently is proceeding in the D.C. Circuit.

The second phase of the Regional Haze Rule begins in 2019 and states must submit regional haze plans for 

this second implementation period in 2021, to continue to demonstrate reasonable progress towards reducing 
visibility impairment in Class I areas. States may need to require additional emissions controls for visibility impairing 
pollutants, including on BART sources, during the second implementation period. We currently cannot predict the 
impact of this second implementation period, if any, on any of our Company’s U.S. subsidiaries.

National Ambient Air Quality Standards ("NAAQS") — Under the CAA, the EPA sets NAAQS for six principal 
pollutants considered harmful to public health and the environment, including ozone, particulate matter, NOx and 
SO2, which result from coal combustion.  Areas meeting the NAAQS are designated "attainment areas" while those 
that do not meet the NAAQS are considered "nonattainment areas." Each state must develop a plan to bring 
nonattainment areas into compliance with the NAAQS, which may include imposing operating limits on individual 
plants. The EPA is required to review NAAQS at five-year intervals.

Based on the current and potential future ambient standards, certain of the states in which the Company's 
subsidiaries operate have determined or will be required to determine whether certain areas within such states 
meet the NAAQS. Some of these states may be required to modify their State Implementation Plans to detail how 
the states will regain their attainment status. As part of this process, it is possible that the applicable state 
environmental regulatory agency or the EPA may require reductions of emissions from our generating stations to 
reach attainment status for ozone, fine particulate matter, NOx or SO2. The compliance costs of the Company's U.S. 
subsidiaries could be material.

On September 30, 2015, IDEM published its final rule establishing reduced SO2 limits for IPL facilities in 
accordance with a new one-hour standard of 75 parts per billion, for the areas in which IPL's Harding Street, 
Petersburg, and Eagle Valley Generating Stations operate. The compliance date for these requirements was 
January 1, 2017. No impact is expected for Eagle Valley or Harding Street Generating Stations because these 
facilities ceased coal combustion prior to the compliance date. It is expected that improvements to the existing 
FGDs at Petersburg will be required in order to comply. IPL estimates costs for compliance at Petersburg at 
approximately $29 million for measures that enhance the performance and integrity of the FGDs systems. On May 
31, 2016, IPL filed its SO2 NAAQS compliance plans with the IURC. IPL is seeking approval for a CPCN for these 
measures at its Petersburg Generating Station. IPL expects to recover through its environmental rate adjustment 
mechanism any operating or capital expenditures related to compliance with these requirements. Recovery of these 
costs is sought through an Indiana statute that allows for 80% recovery of qualifying costs through a rate 
adjustment mechanism, with the remainder recorded as a regulatory asset to be considered for recovery in the next 
base rate case proceeding. However, there can be no assurances that IPL will be successful in that regard. In light 
of the uncertainties at this time, we cannot predict the impact of these permit requirements on our consolidated 
results of operations, cash flows, or financial condition, but it may be material.

Greenhouse Gas Emissions — In January 2011, the EPA began regulating GHG emissions from certain 
50

stationary sources under the so-called "Tailoring Rule." The regulations are being implemented pursuant to two 
CAA programs: the Title V Operating Permit program and the program requiring a permit if undergoing certain new 
construction or major modifications, known as the PSD. Obligations relating to Title V permits include record-
keeping and monitoring requirements. Sources subject to PSD can be required to implement BACT. In June 2014, 
the U.S. Supreme Court ruled that the EPA had exceeded its statutory authority in issuing the Tailoring Rule by 
regulating under the PSD program sources based solely on their GHG emissions. However, the U.S. Supreme 
Court also held that the EPA could impose GHG BACT requirements for sources already required to implement 
PSD for certain other pollutants. Therefore, if future modifications to our U.S.-based businesses' sources require 
PSD review for other pollutants, it may trigger GHG BACT requirements. The EPA has issued guidance on what 
BACT entails for the control of GHG and has now proposed NSPS for modified and reconstructed units (see below) 
that will serve as a floor (maximum emission rate) for future BACT requirements. Individual states are now required 
to determine what controls are required for facilities within their jurisdiction on a case-by-case basis. The ultimate 
impact of the BACT requirements applicable to us on our operations cannot be determined at this time as our U.S.-
based businesses will not be required to implement BACT until one of them constructs a new major source or 
makes a major modification of an existing major source. However, the cost of compliance could be material.

On October 23, 2015, the EPA's rule establishing NSPS for new electric generating units became effective. 

The NSPS establish CO2 emissions standards of 1400 lbs/MWh for newly constructed coal-fueled electric 
generating plants, which reflects the partial capture and storage of CO2 emissions from the plants. The NSPS for 
large, newly constructed NGCC facilities is 1,000 lbs/MWh. These standards apply to any electric generating unit 
with construction commencing after January 8, 2014. The EPA also promulgated NSPS applicable to modified and 
reconstructed electric generating units, which will serve as a floor for future BACT determinations for such units. 
The NSPS applicable to modified and reconstructed coal-fired units will be 1,800 lbs CO2/MWh for sources with 
heat input greater than 2,000 MMBtu per hour. For smaller sources, below 2,000 MMBtu per hour, the standard is 
2,000 lbs CO2/MWh. The NSPS could have an impact on the Company's plans to construct and/or modify or 
reconstruct electric generating units in some locations. 

On December 22, 2015, the EPA's final CO2 emission rules for existing power plants under Clean Air Act 
Section 111(d) (called the CPP) also became effective. The CPP provides for interim emissions performance rates 
that must be achieved beginning in 2022 and final emissions performance rates that must be achieved starting in 
2030. Under the CPP, states are required to meet state-wide emission rate standards or equivalent mass-based 
standards, with the goal being a 32% reduction in total U.S. power sector emissions from 2005 levels by 2030. The 
CPP requires states to submit, by 2016, implementation plans to meet the standards or a request for an extension 
to 2018. If a state fails to develop and submit an approvable implementation plan, the EPA will finalize a federal plan 
for that state. The full impact of the CPP will depend on the following: 

•  whether and how the states in which the Company's U.S. businesses operate respond to the CPP;
•  whether the states adopt an emissions trading regime and, if so, which trading regime; 
•  how other states respond to the CPP, which will affect the size and robustness of any emissions trading market;    

and

•  how other companies may respond in the face of increased carbon costs. 

Several states and industry groups challenged the NSPS for CO2 in the D.C. Circuit. Oral argument on the 
challenges is scheduled for April 2017. We cannot predict at this time the likely outcome of these challenges but, if 
the NSPS is vacated, it also likely would result in the invalidation of the CPP, as EPA’s authority to issue the CPP 
under Section 111(d) of the Clean Air Act is triggered only be EPA’s promulgation of NSPS under Section 111(b) of 
the Clean Air Act.

In addition, several states and industry groups filed petitions in the D.C. Circuit challenging the CPP and 
requested a stay of the rule while the challenge was considered. The D.C. Circuit denied the stay and granted 
requests to consider the challenges on an expedited basis. As a result, the D.C. Circuit may issue an opinion on 
these challenges prior to the end of 2016. On February 9, 2016, the U.S. Supreme Court issued orders staying 
implementation of the CPP pending resolution of challenges to the rule. The challenges have been fully briefed and 
argued before the D.C. Circuit and could be decided by the court at any time. Challenges to the D.C. Circuit’s 
decision could then be filed with the Supreme Court.

The Company will likely not know the answers to the above questions regarding the CPP until 2018 or later. As 

the first compliance period will not end until 2025, and because we cannot predict whether the CPP will survive the 
legal challenges, it is too soon to determine the CPP's potential impact on our business, operations or financial 
condition, but any such impact could be material.

Cooling Water Intake — The Company's facilities are subject to a variety of rules governing water use and 
discharge. In particular, the Company's U.S. facilities are subject to the CWA Section 316(b) rule issued by the EPA 
that seeks to protect fish and other aquatic organisms by requiring existing steam electric generating facilities to 
utilize the BTA for cooling water intake structures. On August 15, 2014, the EPA published its final standards to 
protect fish and other aquatic organisms drawn into cooling water systems at large power plants and other industrial 
facilities. These standards require subject facilities that utilize at least 25% of the withdrawn water exclusively for 
cooling purposes and have a design intake flow of greater than two million gallons per day to choose among seven 
BTA options to reduce fish impingement. In addition, facilities that withdraw at least 125 million gallons per day for 
cooling purposes must conduct studies to assist permitting authorities to determine whether and what site-specific 
controls, if any, would be required to reduce entrainment of aquatic organisms. This decision-making process would 
include public input as part of permit renewal or permit modification. It is possible this process could result in the 
need to install closed-cycle cooling systems (closed-cycle cooling towers), or other technology. Finally, the 
standards require that new units added to an existing facility to increase generation capacity are required to reduce 
both impingement and entrainment that achieves one of two alternatives under national BTA standards for 
entrainment. It is not yet possible to predict the total impacts of this recent final rule at this time, including any 
challenges to such final rule and the outcome of any such challenges. However, if additional capital expenditures 
are necessary, they could be material.

AES Southland's current plan to comply with the California State Water Resources Board's ("SWRCB") 
regulations will see all once-through-cooled ("OTC") generating units retired from service by December 31, 2020. 
New air-cooled combined cycle gas turbine generators and battery energy storage systems will be constructed at 
the AES Alamitos and AES Huntington Beach generating stations and the OTC generating units at the AES 
Redondo Beach generating station will be retired. The execution of the Implementation Plan for compliance with the 
SWRCB's OTC policy is entirely dependent on the Company's ability to execute on long-term power purchase 
agreements to support project financing of the replacement generating units at AES Alamitos and AES Huntington 
Beach. The SWRCB is currently reviewing the Implementation Plan and latest update information to evaluate the 
impact on electrical system reliability, which could result in the extension of OTC compliance dates for specific units.  
The Company’s California subsidiaries have signed 20-year term power purchase agreements with Southern 
California Edison for the new generating capacity which have been approved by the California Public Utilities 
Commission. Approvals and permits to construct the new generating units are pending approval by the California 
Energy Commission and South Coast Air Quality Management District. Construction is scheduled to begin in June 
2017 at AES Huntington Beach and July 2017 at AES Alamitos.

Power plants will be required to comply with the more stringent of state or federal requirements. At present, 

the California state requirements are more stringent and have earlier compliance dates than the federal EPA 
requirements, and are therefore applicable to the Company's California assets. Challenges to the federal EPA's rule 
have been consolidated in the U.S. Court of Appeals for the Second Circuit, although implementation of the rule has 
not been stayed while the challenges proceed. The Company anticipates once-through cooling and CWA Section 
316(b) compliance regulations and costs would have a material impact on our consolidated financial condition or 
results of operations.

Water Discharges — Certain of the Company's U.S.-based businesses are subject to National Pollutant 
Discharge Elimination System permits that regulate specific industrial waste water and storm water discharges to 
the waters of the U.S. under the CWA. On June 29, 2015, the EPA and the U.S. Army Corps of Engineers published 
a final rule defining federal jurisdiction over waters of the U.S.. This rule, which became effective on August 28, 
2015, may expand or otherwise change the number and types of waters or features subject to federal permitting. 
On October 9, 2015, the U.S. Court of Appeals for the Sixth Circuit issued an order to temporarily stay the "Waters 
of the U.S." rule nationwide while that court determines whether it has authority to hear the challenges to the 
rule. The order was in response to challenges brought by 18 states and followed an August 2015 court decision in 
the U.S. District Court of North Dakota to stay the rule in 13 other states. We cannot predict the duration of the 
nationwide or partial stay of the rule or the outcome of this litigation; however, if the rule ultimately survives the legal 
challenges, it could have a material impact on our business, financial condition or results of operations.

On January 7, 2013, the Ohio Environmental Protection Agency issued an NPDES permit for J.M. Stuart 
Station. The primary issues involve the temperature and thermal discharges from the Station including the point at 
which the water quality standards are applied, i.e., whether water quality standards apply at the point where the 
Station discharge canal discharges into the Ohio River, or whether, as the EPA alleges, the discharge canal is an 
extension of Little Three Mile Creek and the water quality standards apply at the point where water enters the 
discharge canal. In addition, there are a number of other water-related permit requirements established with respect 
to metals and other materials contained in the discharges from the Station. The NPDES permit establishes interim 
standards related to the thermal discharge for 54 months that are comparable to current levels of discharge by 

52

Stuart Station. Permanent standards for both temperature and overall thermal discharges are established as of 55 
months after the permit is effective, except that an additional transitional period of approximately 22 months is 
allowed if compliance with the permanent standards is to be achieved through a plan of construction and various 
milestones on the construction schedule are met. It is believed that compliance with the permit as written will 
require capital expenses that will be material to DP&L. The cost of compliance and the timing of such costs is 
uncertain and may vary considerably depending on a compliance plan that would need to be developed, the type of 
capital projects that may be necessary, and the uncertainties that may arise in the likely event that permits and 
approvals from other governmental entities would likely be required to construct and operate any such capital 
project. DP&L has appealed various aspects of the final permit to the Environmental Review Appeals Commission, 
although a hearing date is not currently scheduled. The compliance schedule in the final permit has been modified 
to accommodate the timing of the hearing. The outcome of such appeal is uncertain.

On August 28, 2012, the IDEM issued NPDES permits to the IPL Petersburg, Harding Street and Eagle Valley 

generating stations, which became effective in October 2012. NPDES permits regulate specific industrial 
wastewater and storm water discharges to the waters of Indiana under Sections 402 and 405 of the U.S. Clean 
Water Act. These permits set new water quality-based effluent discharge limits for the Harding Street and 
Petersburg facilities, as well as monitoring and other requirements designed to protect aquatic life, with full 
compliance required by October 2015. In April 2013, IPL received an extension to the compliance deadline through 
September 29, 2017 for IPL's Harding Street and Petersburg facilities through agreed orders with IDEM. IPL 
conducted studies to determine the operational changes and control equipment necessary to comply with the new 
limitations. In October 2014, IPL filed its wastewater compliance plans for its power plants with the IURC. On July 
29, 2015, the IURC approved a Certificate of Public Convenience and Necessity to convert Unit 7 at the Harding 
Street Station from coal-fired to natural gas-fired (about 410 MW net capacity) at a cost of up to $71 million (the 
IURC later approved IPL’s updated cost estimate for the Harding Street Station refuels including $64 million for Unit 
7), and also to install and operate wastewater treatment technologies at Harding Street Station and Petersburg 
Generating Station at a cost of up to $326 million. The IURC order also granted IPL authority for timely rate 
recovery for 80% of the costs of these projects and authority to defer the remaining 20% as a regulatory asset to be 
considered for recovery through IPL’s next basic rate case proceeding. However, there can be no assurances that 
IPL will be successful in that regard.

On November 3, 2015, the EPA published its final ELG rule to reduce toxic pollutants discharged into waters of 

the U.S. by power plants. These effluent limitations for existing and new sources include dry handling of fly ash, 
closed-loop or dry handling of bottom ash and more stringent effluent limitations for flue gas de-sulfurization 
wastewater. Compliance time lines for existing sources will be established by the applicable permitting authorities 
and will be set as soon as determined possible, but no sooner than November 1, 2018 and no later than December 
31, 2023. IPL plans to install a dry bottom ash handling system in response to the CCR rule described below in 
advance of the ELG compliance date. As such, the impact of the ELG rule is not expected to be material. While we 
are still evaluating the impacts of the final rule for DP&L, we anticipate that implementation of the requirements will 
have a material adverse effect on our results of operations, financial condition and cash flows.

Selenium Rule — NPDES permits may be updated to include Selenium water quality based effluent limits 

based on a site specific evaluation process which includes determining if there is a reasonable potential to exceed 
the revised final Selenium water quality standards for the specific receiving water body utilizing actual and/or project 
discharge information for the generating facilities. As a result, it is not yet possible to predict the total impacts of this 
final rule at this time, including any challenges to such final rule and the outcome of any such challenges. However, 
if additional capital expenditures are necessary, they could be material. IPL would seek recovery of these capital 
expenditures; however, there is no guarantee it would be successful in this regard.

Waste Management — In the course of operations, the Company's facilities generate solid and liquid waste 
materials requiring eventual disposal or processing. With the exception of coal combustion residuals ("CCR"), the 
wastes are not usually physically disposed of on our property, but are shipped off site for final disposal, treatment or 
recycling. CCR, which consists of bottom ash, fly ash and air pollution control wastes, is disposed of at some of our 
coal-fired power generation plant sites using engineered, permitted landfills. Waste materials generated at our 
electric power and distribution facilities may include asbestos, CCR, oil, scrap metal, rubbish, small quantities of 
industrial hazardous wastes such as spent solvents, tree and land clearing wastes and PCB contaminated liquids 
and solids. The Company endeavors to ensure that all of its solid and liquid wastes are disposed of in accordance 
with applicable national, regional, state and local regulations. On October 19, 2015, an EPA rule regulating CCR 
under the Resource Conservation and Recovery Act as nonhazardous solid waste became effective. The rule 
established nationally applicable minimum criteria for the disposal of CCR in new and currently operating landfills 
and surface impoundments, and may impose closure and/or corrective action requirements for existing CCR 
landfills and impoundments under certain specified conditions. The primary enforcement mechanisms under this 

53

regulation would be actions commenced by the states and private lawsuits. On December 16, 2016, President 
Obama signed into law the Water Infrastructure Improvements for the Nation Act (WIN Act), which includes 
provisions to implement the CCR rule through a state permitting program, or if the state chooses not to participate, 
a possible federal permit program.

The existing ash ponds at IPL's Petersburg Station do not meet certain structural stability requirements set 
forth in the CCR rule. As such, IPL would be required to cease use of the ash ponds by April 17, 2017. However, 
IDEM has granted IPL a variance extending that deadline to April 11, 2018. In order to handle the bottom ash 
material that would otherwise be sluiced to the ash ponds, IPL plans to install a dry bottom ash handling system at 
an estimated cost of approximately $47 million. On May 31, 2016, IPL filed its CCR compliance plans with the 
IURC. IPL is seeking approval for a CPCN to install the bottom ash dewatering system at its Petersburg generating 
station. IPL expects to recover through its environmental rate adjustment mechanism any operating or capital 
expenditures related to the installation of this system. Recovery of these costs is sought through an Indiana statute 
that allows for 80% recovery of qualifying costs through a rate adjustment mechanism with the remainder recorded 
as a regulatory asset to be considered for recovery in the next base rate case proceeding. However, there can be 
no assurances that IPL will be successful in that regard. In light of the uncertainties at this time, we cannot predict 
the impact of these requirements on our consolidated results of operations, cash flows, or financial condition, but it 
may be material.

CERCLA — The Comprehensive Environmental Response, Compensation and Liability Act of 1980 (aka 

"Superfund") may be the source of claims against certain of the Company's U.S. subsidiaries from time to 
time. There is ongoing litigation at a site known as the South Dayton Landfill where a group of companies already 
recognized as potentially responsible parties have sued DP&L and other unrelated entities seeking a contribution 
toward the costs of assessment and remediation. DP&L is actively opposing such claims. In 2003, DP&L received 
notice that the EPA considers DP&L to be a potentially responsible party at the Tremont City landfill Superfund 
site. EPA has taken no further action with respect to DP&L since 2003 regarding the Tremont City landfill. The 
Company is unable to determine whether there will be any liability, or the size of any liability that may ultimately be 
assessed against DP&L at these two sites, but any such liability could be material to DP&L.

Unit Retirement and Replacement Generation — In the second quarter of 2013, IPL retired in place five oil-

fired peaking units with an average life of approximately 61 years (approximately 168 MW net capacity in total), as 
such units were not equipped with the advanced environmental control technologies needed to comply with existing 
and expected environmental regulations. Although these units represented approximately 5% of IPL's generating 
capacity, they were seldom dispatched by Midcontinent Independent System Operator, Inc. in recent years due to 
their relatively higher production cost and in some instances repairs were needed. In addition to these recently 
retired units, IPL has several other generating units that it expects to retire or refuel by 2017. These units are 
primarily coal-fired and represent 472 MW of net capacity in total. To replace this generation, in April 2013, IPL filed 
a petition and case-in-chief with the IURC in April 2013 seeking a CPCN to build a 550 to 725 MW CCGT at its 
Eagle Valley Station site in Indiana and to refuel Harding Street Station Units 5 and 6 from coal to natural gas (106 
MW net capacity each). In May 2014, the IURC issued an order on the CPCN authorizing the refueling project and 
granting approval to build a 644 to 685 MW CCGT at a total budget of $649 million. The current estimated cost of 
these projects is $632 million. IPL was granted authority to accrue post in-service allowance for debt and equity 
funds used during construction and to defer the recognition of depreciation expense of the CCGT and refueling 
project until such time that IPL is allowed to collect both a return and depreciation expense on the CCGT and 
refueling project. The CCGT is expected to be placed into service in the first half of 2018, and the refueling project 
was completed in December 2015. The costs to build and operate the CCGT and for the refueling project, other 
than fuel costs, will not be recoverable by IPL through rates until the conclusion of a base rate case proceeding with 
the IURC after the assets have been placed in service. For a discussion of the retirement of AES Southland's OTC 
generating units due to U.S. cooling water intake regulations, please see — Cooling Water Intake, above.

ITEM 1A. RISK FACTORS 

You should consider carefully the following risks, along with the other information contained in or incorporated 

by reference in this Form 10-K. Additional risks and uncertainties also may adversely affect our business and 
operations including those discussed in Item 7.—Management's Discussion and Analysis of Financial Condition and 
Results of Operations in this Form 10-K. If any of the following events actually occur, our business, financial results 
and financial condition could be materially adversely affected.

We routinely encounter and address risks, some of which may cause our future results to be different, 
sometimes materially different, than we presently anticipate. The categories of risk we have identified in Item 1A.—
Risk Factors of this Form 10-K include the following:

risks related to our high level of indebtedness;
risks associated with our ability to raise needed capital;

• 
• 
•  external risks associated with revenue and earnings volatility;
• 
• 

risks associated with our operations; and
risks associated with governmental regulation and laws.

These risk factors should be read in conjunction with Item 7.—Management's Discussion and Analysis of 

Financial Condition and Results of Operations, and the Consolidated Financial Statements and related notes 
included elsewhere in this report.

Risks Related to our High Level of Indebtedness

We have a significant amount of debt, a large percentage of which is secured, which could adversely 

affect our business and the ability to fulfill our obligations.

As of December 31, 2016, we had approximately $20.5 billion of outstanding indebtedness on a consolidated 
basis. All outstanding borrowings, if any, under The AES Corporation's senior secured credit facility are secured by 
certain of our assets, including the pledge of capital stock of many of The AES Corporation's directly held 
subsidiaries. Most of the debt of The AES Corporation's subsidiaries is secured by substantially all of the assets of 
those subsidiaries. Since we have such a high level of debt, a substantial portion of cash flow from operations must 
be used to make payments on this debt. Furthermore, since a significant percentage of our assets are used to 
secure this debt, this reduces the amount of collateral that is available for future secured debt or credit support and 
reduces our flexibility in dealing with these secured assets. This high level of indebtedness and related security 
could have other important consequences to us and our investors, including:

•  making it more difficult to satisfy debt service and other obligations at the holding company and/or individual 

subsidiaries;

• 

• 

• 

• 

increasing the likelihood of a downgrade of our debt, which could cause future debt costs and/or payments to 
increase under our debt and related hedging instruments and consume an even greater portion of cash flow;

increasing our vulnerability to general adverse industry and economic conditions, including but not limited to 
adverse changes in foreign exchange rates and commodity prices;

reducing the availability of cash flow to fund other corporate purposes and grow our business;

limiting our flexibility in planning for, or reacting to, changes in our business and the industry;

•  placing us at a competitive disadvantage to our competitors that are not as highly leveraged; and

• 

limiting, along with the financial and other restrictive covenants relating to such indebtedness, among other 
things, our ability to borrow additional funds as needed or take advantage of business opportunities as they 
arise, pay cash dividends or repurchase common stock.

The agreements governing our indebtedness, including the indebtedness of our subsidiaries, limit, but do not 

prohibit the incurrence of additional indebtedness. To the extent we become more leveraged, the risks described 

57

above would increase. Further, our actual cash requirements in the future may be greater than expected. 
Accordingly, our cash flows may not be sufficient to repay at maturity all of the outstanding debt as it becomes due 
and, in that event, we may not be able to borrow money, sell assets, raise equity or otherwise raise funds on 
acceptable terms or at all to refinance our debt as it becomes due. See Note 11—Debt included in Item 8. of this 
Form 10-K for a schedule of our debt maturities.

The AES Corporation is a holding company and its ability to make payments on its outstanding 

indebtedness, including its public debt securities, is dependent upon the receipt of funds from its 
subsidiaries by way of dividends, fees, interest, loans or otherwise.

The AES Corporation is a holding company with no material assets other than the stock of its subsidiaries. All 

of The AES Corporation's revenue is generated through its subsidiaries. Accordingly, almost all of The AES 
Corporation's cash flow is generated by the operating activities of its subsidiaries. Therefore, The AES 
Corporation's ability to make payments on its indebtedness and to fund its other obligations is dependent not only 
on the ability of its subsidiaries to generate cash, but also on the ability of the subsidiaries to distribute cash to it in 
the form of dividends, fees, interest, tax sharing payments, loans or otherwise.

However, our subsidiaries face various restrictions in their ability to distribute cash to The AES Corporation. 

Most of the subsidiaries are obligated, pursuant to loan agreements, indentures or non-recourse financing 
arrangements, to satisfy certain restricted payment covenants or other conditions before they may make 
distributions to The AES Corporation. In addition, the payment of dividends or the making of loans, advances or 
other payments to The AES Corporation may be subject to other contractual, legal or regulatory restrictions or may 
be prohibited altogether. Business performance and local accounting and tax rules may limit the amount of retained 
earnings that may be distributed to us as a dividend. Subsidiaries in foreign countries may also be prevented from 
distributing funds to The AES Corporation as a result of foreign governments restricting the repatriation of funds or 
the conversion of currencies. Any right that The AES Corporation has to receive any assets of any of its subsidiaries 
upon any liquidation, dissolution, winding up, receivership, reorganization, bankruptcy, insolvency or similar 
proceedings (and the consequent right of the holders of The AES Corporation's indebtedness to participate in the 
distribution of, or to realize proceeds from, those assets) will be effectively subordinated to the claims of any such 
subsidiary's creditors (including trade creditors and holders of debt issued by such subsidiary).

The AES Corporation's subsidiaries are separate and distinct legal entities and, unless they have expressly 
guaranteed any of The AES Corporation's indebtedness, have no obligation, contingent or otherwise, to pay any 
amounts due pursuant to such debt or to make any funds available whether by dividends, fees, loans or other 
payments. 

Even though The AES Corporation is a holding company, existing and potential future defaults by 

subsidiaries or affiliates could adversely affect The AES Corporation.

We attempt to finance our domestic and foreign projects primarily under loan agreements and related 
documents which, except as noted below, require the loans to be repaid solely from the project's revenues and 
provide that the repayment of the loans (and interest thereon) is secured solely by the capital stock, physical 
assets, contracts and cash flow of that project subsidiary or affiliate. This type of financing is usually referred to as 
non-recourse debt or "non-recourse financing." In some non-recourse financings, The AES Corporation has 
explicitly agreed to undertake certain limited obligations and contingent liabilities, most of which by their terms will 
only be effective or will be terminated upon the occurrence of future events. These obligations and liabilities take 
the form of guarantees, indemnities, letters of credit, letter of credit reimbursement agreements and agreements to 
pay, in certain circumstances, the project lenders or other parties.

As of December 31, 2016, we had approximately $20.5 billion of outstanding indebtedness on a consolidated 

basis, of which approximately $4.7 billion was recourse debt of The AES Corporation and approximately $15.8 
billion was non-recourse debt. In addition, we have outstanding guarantees, indemnities, letters of credit, and other 
credit support commitments which are further described in this Form 10-K in Item 7.—Management's Discussion 
and Analysis of Financial Condition and Results of Operations—Capital Resources and Liquidity—Parent Company 
Liquidity.

Some of our subsidiaries are currently in default with respect to all or a portion of their outstanding 

indebtedness. The total debt classified as current in our Consolidated Balance Sheets related to such defaults was 
$128 million as of December 31, 2016. While the lenders under our non-recourse financings generally do not have 
direct recourse to The AES Corporation (other than to the extent of any credit support given by The AES 
Corporation), defaults thereunder can still have important consequences for The AES Corporation, including, 
without limitation:

58

• 

reducing The AES Corporation's receipt of subsidiary dividends, fees, interest payments, loans and other 
sources of cash since the project subsidiary will typically be prohibited from distributing cash to The AES 
Corporation during the pendency of any default;

•  under certain circumstances, triggering The AES Corporation's obligation to make payments under any financial 
guarantee, letter of credit or other credit support which The AES Corporation has provided to or on behalf of 
such subsidiary;

•  causing The AES Corporation to record a loss in the event the lender forecloses on the assets;

• 

• 

• 

triggering defaults in The AES Corporation's outstanding debt and trust preferred securities. For example, The 
AES Corporation's senior secured credit facility and outstanding senior notes include events of default for certain 
bankruptcy related events involving material subsidiaries. In addition, The AES Corporation's senior secured 
credit facility includes certain events of default relating to accelerations of outstanding material debt of material 
subsidiaries or any subsidiaries that in the aggregate constitute a material subsidiary;
the loss or impairment of investor confidence in the Company; or

foreclosure on the assets that are pledged under the non-recourse loans, therefore eliminating any and all 
potential future benefits derived from those assets.

None of the projects that are currently in default are owned by subsidiaries that individually or in the aggregate 

meet the applicable standard of materiality in The AES Corporation's senior secured credit facility or other debt 
agreements in order for such defaults to trigger an event of default or permit acceleration under such indebtedness. 
However, as a result of future mix of distributions, write-down of assets, dispositions and other matters that affect 
our financial position and results of operations, it is possible that one or more of these subsidiaries, individually or in 
the aggregate, could fall within the applicable standard of materiality and thereby upon an acceleration of such 
subsidiary's debt, trigger an event of default and possible acceleration of the indebtedness under The AES 
Corporation's senior secured credit facility or other indebtedness of The AES Corporation.

Risks Associated with our Ability to Raise Needed Capital

The AES Corporation, or the Parent Company, has significant cash requirements and limited sources 

of liquidity.

The AES Corporation requires cash primarily to fund:

interest and preferred dividends;

•  principal repayments of debt;
• 
•  acquisitions;
•  construction and other project commitments;
•  other equity commitments, including business development investments;
•  equity repurchases and/or cash dividends on our common stock;
• 
•  Parent Company overhead costs.

taxes; and

The AES Corporation's principal sources of liquidity are:

•  dividends and other distributions from its subsidiaries;

•  proceeds from debt and equity financings at the Parent Company level; and

•  proceeds from asset sales.

For a more detailed discussion of The AES Corporation's cash requirements and sources of liquidity, please 

see Item 7.—Management's Discussion and Analysis of Financial Condition and Results of Operations—Capital 
Resources and Liquidity in this Form 10-K.

While we believe that these sources will be adequate to meet our obligations at the Parent Company level for 

the foreseeable future, this belief is based on a number of material assumptions, including, without limitation, 
assumptions about our ability to access the capital or commercial lending markets, the operating and financial 
performance of our subsidiaries, exchange rates, our ability to sell assets, and the ability of our subsidiaries to pay 
dividends and other distributions. Any number of assumptions could prove to be incorrect, and, therefore there can 
be no assurance that these sources will be available when needed or that our actual cash requirements will not be 
greater than expected. For example, in recent years, certain financial institutions have gone bankrupt. In the event 
that a bank who is party to our senior secured credit facility or other facilities goes bankrupt or is otherwise unable 

59

to fund its commitments, we would need to replace that bank in our syndicate or risk a reduction in the size of the 
facility, which would reduce our liquidity. In addition, our cash flow may not be sufficient to repay at maturity the 
entire principal outstanding under our credit facility and our debt securities and we may have to refinance such 
obligations. There can be no assurance that we will be successful in obtaining such refinancing on terms 
acceptable to us or at all and any of these events could have a material effect on us.

Our ability to grow our business could be materially adversely affected if we were unable to raise 

capital on favorable terms.

From time to time, we rely on access to capital markets as a source of liquidity for capital requirements not 
satisfied by operating cash flows. Our ability to arrange for financing on either a recourse or non-recourse basis and 
the costs of such capital are dependent on numerous factors, some of which are beyond our control, including:

•  general economic and capital market conditions;

• 
• 

• 

the availability of bank credit;
investor confidence;

the financial condition, performance and prospects of The AES Corporation in general and/or that of any 
subsidiary requiring the financing as well as companies in our industry or similar financial circumstances; and

•  changes in tax and securities laws which are conducive to raising capital.

Should future access to capital not be available to us, we may have to sell assets or decide not to build new 

plants or expand or improve existing facilities, either of which would affect our future growth, results of operations or 
financial condition.

A downgrade in the credit ratings of The AES Corporation or its subsidiaries could adversely affect 
our ability to access the capital markets which could increase our interest costs or adversely affect our 
liquidity and cash flow.

If any of the credit ratings of The AES Corporation or its subsidiaries were to be downgraded, our ability to 
raise capital on favorable terms could be impaired and our borrowing costs could increase. Furthermore, depending 
on The AES Corporation's credit ratings and the trading prices of its equity and debt securities, counterparties may 
no longer be as willing to accept general unsecured commitments by The AES Corporation to provide credit 
support. Accordingly, with respect to both new and existing commitments, The AES Corporation may be required to 
provide some other form of assurance, such as a letter of credit and/or collateral, to backstop or replace any credit 
support by The AES Corporation. There can be no assurance that such counterparties will accept such guarantees 
or that AES could arrange such further assurances in the future. In addition, to the extent The AES Corporation is 
required and able to provide letters of credit or other collateral to such counterparties, it will limit the amount of 
credit available to The AES Corporation to meet its other liquidity needs.

We may not be able to raise sufficient capital to fund developing projects in certain less developed 

economies which could change or in some cases adversely affect our growth strategy.

Part of our strategy is to grow our business by developing businesses in less developed economies where the 

return on our investment may be greater than projects in more developed economies. Commercial lending 
institutions sometimes refuse to provide non-recourse project financing in certain less developed economies, and in 
these situations we have sought and will continue to seek direct or indirect (through credit support or guarantees) 
project financing from a limited number of multilateral or bilateral international financial institutions or agencies. As a 
precondition to making such project financing available, the lending institutions may also require governmental 
guarantees for certain project and sovereign related risks. There can be no assurance, however, that project 
financing from the international financial agencies or that governmental guarantees will be available when needed, 
and if they are not, we may have to abandon the project or invest more of our own funds which may not be in line 
with our investment objectives and would leave less funds for other projects.

External Risks Associated with Revenue and Earnings Volatility

Our businesses may incur substantial costs and liabilities and be exposed to price volatility as a 
result of risks associated with the wholesale electricity markets, which could have a material adverse effect 
on our financial performance.

Some of our businesses sell electricity in the spot markets in cases where they operate at levels in excess of 

their power sales agreements or retail load obligations. Our businesses may also buy electricity in the wholesale 
spot markets. As a result, we are exposed to the risks of rising and falling prices in those markets. The open market 
wholesale prices for electricity can be volatile and often reflect the fluctuating cost of fuels such as coal, natural gas 

60

or oil derivative fuels in addition to other factors described below. Consequently, any changes in the supply and cost 
of coal, natural gas, or oil derivative fuels may impact the open market wholesale price of electricity.

Volatility in market prices for fuel and electricity may result from among other things:

•  plant availability in the markets generally;

•  availability and effectiveness of transmission facilities owned and operated by third parties;
•  competition;

•  electricity usage;
•  seasonality;

foreign exchange rate fluctuation;

• 
•  availability and price of emission credits;

•  hydrology and other weather conditions;
• 

illiquid markets;

transmission or transportation constraints or inefficiencies;

• 
•  availability of competitively priced renewables sources;

increased adoption of distributed generation;

• 
•  available supplies of natural gas, crude oil and refined products, and coal;
•  generating unit performance;
•  natural disasters, terrorism, wars, embargoes, and other catastrophic events;
•  energy, market and environmental regulation, legislation and policies;
•  geopolitical concerns affecting global supply of oil and natural gas;
•  general economic conditions in areas where we operate which impact energy consumption; and
•  bidding behavior and market bidding rules.

Our financial position and results of operations may fluctuate significantly due to fluctuations in 

currency exchange rates experienced at our foreign operations.

Our exposure to currency exchange rate fluctuations results primarily from the translation exposure associated 
with the preparation of the Consolidated Financial Statements, as well as from transaction exposure associated with 
transactions in currencies other than an entity's functional currency. While the Consolidated Financial Statements 
are reported in U.S. Dollars, the financial statements of many of our subsidiaries outside the U.S. are prepared 
using the local currency as the functional currency and translated into U.S. Dollars by applying appropriate 
exchange rates. As a result, fluctuations in the exchange rate of the U.S. Dollar relative to the local currencies 
where our subsidiaries outside the U.S. report could cause significant fluctuations in our results. In addition, while 
our expenses with respect to foreign operations are generally denominated in the same currency as corresponding 
sales, we have transaction exposure to the extent receipts and expenditures are not denominated in the 
subsidiary's functional currency. Moreover, the costs of doing business abroad may increase as a result of adverse 
exchange rate fluctuations. Our financial position and results of operations could be affected by fluctuations in the 
value of a number of currencies. See Item 7A.—Quantitative and Qualitative Disclosures about Market Risk to this 
Form 10-K for further information.

We may not be adequately hedged against our exposure to changes in commodity prices or interest 

rates.

We routinely enter into contracts to hedge a portion of our purchase and sale commitments for electricity, fuel 

requirements and other commodities to lower our financial exposure related to commodity price fluctuations. As part 
of this strategy, we routinely utilize fixed price or indexed forward physical purchase and sales contracts, futures, 
financial swaps, and option contracts traded in the over-the-counter markets or on exchanges. We also enter into 
contracts which help us manage our interest rate exposure. However, we may not cover the entire exposure of our 
assets or positions to market price or interest rate volatility, and the coverage will vary over time. Furthermore, the 
risk management practices we have in place may not always perform as planned. In particular, if prices of 
commodities or interest rates significantly deviate from historical prices or interest rates or if the price or interest 
rate volatility or distribution of these changes deviates from historical norms, our risk management practices may 
not protect us from significant losses. As a result, fluctuating commodity prices or interest rates may negatively 
impact our financial results to the extent we have unhedged or inadequately hedged positions. In addition, certain 
types of economic hedging activities may not qualify for hedge accounting under U.S. GAAP, resulting in increased 

61

volatility in our net income. The Company may also suffer losses associated with "basis risk" which is the difference 
in performance between the hedge instrument and the targeted underlying exposure. Furthermore, there is a risk 
that the current counterparties to these arrangements may fail or are unable to perform part or all of their obligations 
under these arrangements.

Our coal-fired facilities in the U.S. continue to face substantial challenges as a result of high coal prices 
relative to natural gas, particularly those which are merchant plants that are exposed to market risk and those that 
have hybrid merchant risk, meaning those businesses that have a PPA in place but purchase fuel at market prices 
or under short term contracts. For our businesses with PPA pricing that does not perfectly pass through our fuel 
costs, the businesses attempt to manage the exposure through flexible fuel purchasing and timing of entry and 
terms of our fuel supply agreements; however, these risk management efforts may not be successful and the 
resulting commodity exposure could have a material impact on these businesses and/or our results of operations.

Supplier and/or customer concentration may expose the Company to significant financial credit or 

performance risks.

We often rely on a single contracted supplier or a small number of suppliers for the provision of fuel, 
transportation of fuel and other services required for the operation of certain of our facilities. If these suppliers 
cannot perform, we would seek to meet our fuel requirements by purchasing fuel at market prices, exposing us to 
market price volatility and the risk that fuel and transportation may not be available during certain periods at any 
price, which could adversely impact the profitability of the affected business and our results of operations, and could 
result in a breach of agreements with other counterparties, including, without limitation, offtakers or lenders.

At times, we rely on a single customer or a few customers to purchase all or a significant portion of a facility's 

output, in some cases under long-term agreements that account for a substantial percentage of the anticipated 
revenue from a given facility. We have also hedged a portion of our exposure to power price fluctuations through 
forward fixed price power sales. Counterparties to these agreements may breach or may be unable to perform their 
obligations. We may not be able to enter into replacement agreements on terms as favorable as our existing 
agreements, or at all. If we were unable to enter into replacement PPAs, these businesses may have to sell power 
at market prices. A breach by a counterparty of a PPA or other agreement could also result in the breach of other 
agreements, including, without limitation, the debt documents of the affected business. 

The failure of any supplier or customer to fulfill its contractual obligations to The AES Corporation or our 
subsidiaries could have a material adverse effect on our financial results. Consequently, the financial performance 
of our facilities is dependent on the credit quality of, and continued performance by, suppliers and customers.

The market pricing of our common stock has been volatile and may continue to be volatile in future 

periods.

The market price for our common stock has been volatile in the past, and the price of our common stock could 
fluctuate substantially in the future. Stock price movements on a quarter-by-quarter basis for the past two years are 
presented in Item 5.—Market—Market Information of this Form 10-K. Factors that could affect the price of our 
common stock in the future include general conditions in our industry, in the power markets in which we participate 
and in the world, including environmental and economic developments, over which we have no control, as well as 
developments specific to us, including, risks that could result in revenue and earnings volatility as well as other risk 
factors described in Item 1A.—Risk Factors and those matters described in Item 7.—Management's Discussion and 
Analysis of Financial Conditions and Results of Operations.

Risks Associated with our Operations

We do a significant amount of business outside the U.S., including in developing countries, which 

presents significant risks.

A significant amount of our revenue is generated outside the U.S. and a significant portion of our international 

operations is conducted in developing countries. Part of our growth strategy is to expand our business in certain 
developing countries in which AES has an existing presence as such countries may have higher growth rates and 
offer greater opportunities to expand from our platforms, with potentially higher returns than in some more 
developed countries. International operations, particularly the operation, financing and development of projects in 
developing countries, entail significant risks and uncertainties, including, without limitation:

•  economic, social and political instability in any particular country or region;

•  adverse changes in currency exchange rates;

•  government restrictions on converting currencies or repatriating funds;

•  unexpected changes in foreign laws and regulations or in trade, monetary or fiscal policies;

62

•  high inflation and monetary fluctuations;

• 
• 

• 

restrictions on imports of coal, oil, gas or other raw materials required by our generation businesses to operate;
threatened or consummated expropriation or nationalization of our assets by foreign governments;

risks relating to the failure to comply with the U.S. Foreign Corrupt Practices Act, United Kingdom Bribery Act or 
other anti-bribery laws applicable to our operations;

•  difficulties in hiring, training and retaining qualified personnel, particularly finance and accounting personnel with 

GAAP expertise;

•  unwillingness of governments and their agencies, similar organizations or other counterparties to honor their 

contracts;

•  unwillingness of governments, government agencies, courts or similar bodies to enforce contracts that are 

economically advantageous to subsidiaries of the Company and economically unfavorable to counterparties, 
against such counterparties, whether such counterparties are governments or private parties;

inability to obtain access to fair and equitable political, regulatory, administrative and legal systems;

• 
•  adverse changes in government tax policy;

•  difficulties in enforcing our contractual rights or enforcing judgments or obtaining a favorable result in local 

jurisdictions; and

•  potentially adverse tax consequences of operating in multiple jurisdictions.

Any of these factors, by itself or in combination with others, could materially and adversely affect our business, 

results of operations and financial condition. Our operations may experience volatility in revenues and operating 
margin which have caused and are expected to cause significant volatility in our results of operations and cash 
flows. The volatility is caused by regulatory and economic difficulties, political instability and currency devaluations 
being experienced in many of these countries. This volatility reduces the predictability and enhances the uncertainty 
associated with cash flows from these businesses. A number of our businesses are facing challenges associated 
with regulatory changes. 

The operation of power generation, distribution and transmission facilities involves significant risks 

that could adversely affect our financial results. We and/or our subsidiaries may not have adequate risk 
mitigation and/or insurance coverage for liabilities.

We are in the business of generating and distributing electricity, which involves certain risks that can adversely 

affect financial and operating performance, including:

•  changes in the availability of our generation facilities or distribution systems due to increases in scheduled and 

unscheduled plant outages, equipment failure, failure of transmission systems, labor disputes, disruptions in fuel 
supply, poor hydrologic and wind conditions, inability to comply with regulatory or permit requirements or 
catastrophic events such as fires, floods, storms, hurricanes, earthquakes, dam failures, explosions, terrorist 
acts, cyber attacks or other similar occurrences; and

•  changes in our operating cost structure including, but not limited to, increases in costs relating to gas, coal, oil 
and other fuel; fuel transportation; purchased electricity; operations, maintenance and repair; environmental 
compliance, including the cost of purchasing emissions offsets and capital expenditures to install environmental 
emission equipment; transmission access; and insurance.

Our businesses require reliable transportation sources (including related infrastructure such as roads, ports 

and rail), power sources and water sources to access and conduct operations. The availability and cost of this 
infrastructure affects capital and operating costs and levels of production and sales. Limitations, or interruptions in 
this infrastructure or at the facilities of our subsidiaries, including as a result of third parties intentionally or 
unintentionally disrupting this infrastructure or the facilities of our subsidiaries, could impede their ability to produce 
electricity. This could have a material adverse effect on our businesses' results of operations, financial condition and 
prospects.

In addition, a portion of our generation facilities were constructed many years ago. Older generating 

equipment may require significant capital expenditures for maintenance. The equipment at our plants, whether old 
or new, is also likely to require periodic upgrading, improvement or repair, and replacement equipment or parts may 
be difficult to obtain in circumstances where we rely on a single supplier or a small number of suppliers. The 
inability to obtain replacement equipment or parts may impact the ability of our plants to perform and could, 
therefore, have a material impact on our business and results of operations. Breakdown or failure of one of our 
operating facilities may prevent the facility from performing under applicable power sales agreements which, in 
certain situations, could result in termination of a power purchase or other agreement or incurrence of a liability for 

63

liquidated damages and/or other penalties.

As a result of the above risks and other potential hazards associated with the power generation, distribution 
and transmission industries, we may from time to time become exposed to significant liabilities for which we may 
not have adequate risk mitigation and/or insurance coverage. Power generation involves hazardous activities, 
including acquiring, transporting and unloading fuel, operating large pieces of rotating equipment and delivering 
electricity to transmission and distribution systems. In addition to natural risks, such as earthquakes, floods, 
lightning, hurricanes and wind, hazards, such as fire, explosion, collapse and machinery failure, are inherent risks in 
our operations which may occur as a result of inadequate internal processes, technological flaws, human error or 
actions of third parties or other external events. The control and management of these risks depend upon adequate 
development and training of personnel and on the existence of operational procedures, preventative maintenance 
plans and specific programs supported by quality control systems which reduce, but do not eliminate, the possibility 
of the occurrence and impact of these risks.

The hazards described above, along with other safety hazards associated with our operations, can cause 

significant personal injury or loss of life, severe damage to and destruction of property, plant and equipment, 
contamination of, or damage to, the environment and suspension of operations. The occurrence of any one of these 
events may result in our being named as a defendant in lawsuits asserting claims for substantial damages, 
environmental cleanup costs, personal injury and fines and/or penalties. We maintain an amount of insurance 
protection that we believe is customary, but there can be no assurance that our insurance will be sufficient or 
effective under all circumstances and against all hazards or liabilities to which we may be subject. A claim for which 
we are not fully insured or insured at all could hurt our financial results and materially harm our financial condition. 
Further, due to the cyclical nature of the insurance markets, we cannot provide assurance that insurance coverage 
will continue to be available on terms similar to those presently available to us or at all. Any losses not covered by 
insurance could have a material adverse effect on our financial condition, results of operations or cash flows.

Our businesses' insurance does not cover every potential risk associated with its operations. Adequate 
coverage at reasonable rates is not always obtainable. In addition, insurance may not fully cover the liability or the 
consequences of any business interruptions such as equipment failure or labor dispute. The occurrence of a 
significant adverse event not fully or partially covered by insurance could have a material adverse effect on the 
Company's business, results or operations, financial condition and prospects.

Any of the above risks could have a material adverse effect on our business and results of operations.

We may not be able to attract and retain skilled people, which could have a material adverse effect on 

our operations.

Our operating success and ability to carry out growth initiatives depends in part on our ability to retain 

executives and to attract and retain additional qualified personnel who have experience in our industry and in 
operating a company of our size and complexity, including people in our foreign businesses. The inability to attract 
and retain qualified personnel could have a material adverse effect on our business, because of the difficulty of 
promptly finding qualified replacements. For example, we routinely are required to assess the financial impacts of 
complicated business transactions which occur on a worldwide basis. These assessments are dependent on hiring 
personnel on a worldwide basis with sufficient expertise in U.S. GAAP to timely and accurately comply with U.S. 
reporting obligations. An inability to maintain adequate internal accounting and managerial controls and hire and 
retain qualified personnel could have an adverse effect on our financial and tax reporting.

We have contractual obligations to certain customers to provide full requirements service, which 
makes it difficult to predict and plan for load requirements and may result in increased operating costs to 
certain of our businesses.

We have contractual obligations to certain customers to supply power to satisfy all or a portion of their energy 

requirements. The uncertainty regarding the amount of power that our power generation and distribution facilities 
must be prepared to supply to customers may increase our operating costs. A significant under- or over-estimation 
of load requirements could result in our facilities not having enough or having too much power to cover their 
obligations, in which case we would be required to buy or sell power from or to third parties at prevailing market 
prices. Those prices may not be favorable and thus could increase our operating costs.

We may not be able to enter into long-term contracts, which reduce volatility in our results of 

operations. Even when we successfully enter into long-term contracts, our generation businesses are often 
dependent on one or a limited number of customers and a limited number of fuel suppliers.

Many of our generation plants conduct business under long-term sales and supply contracts, which helps 
these businesses to manage risks by reducing the volatility associated with power and input costs and providing a 
64

stable revenue and cost structure. In these instances, we rely on power sales contracts with one or a limited 
number of customers for the majority of, and in some cases all of, the relevant plant's output and revenues over the 
term of the power sales contract. The remaining terms of the power sales contracts of our generation plants range 
from one to 25 years. In many cases, we also limit our exposure to fluctuations in fuel prices by entering into long-
term contracts for fuel with a limited number of suppliers. In these instances, the cash flows and results of 
operations are dependent on the continued ability of customers and suppliers to meet their obligations under the 
relevant power sales contract or fuel supply contract, respectively. Some of our long-term power sales agreements 
are at prices above current spot market prices and some of our long-term fuel supply contracts are at prices below 
current market prices. The loss of significant power sales contracts or fuel supply contracts, or the failure by any of 
the parties to such contracts that prevents us from fulfilling our obligations thereunder, could adversely impact our 
strategy by resulting in costs that exceed revenue, which could have a material adverse impact on our business, 
results of operations and financial condition. In addition, depending on market conditions and regulatory regimes, it 
may be difficult for us to secure long-term contracts, either where our current contracts are expiring or for new 
development projects. The inability to enter into long-term contracts could require many of our businesses to 
purchase inputs at market prices and sell electricity into spot markets, which may not be favorable. 

We have sought to reduce counterparty credit risk under our long-term contracts in part by entering into power 

sales contracts with utilities or other customers of strong credit quality and by obtaining guarantees from certain 
sovereign governments of the customer's obligations. However, many of our customers do not have, or have failed 
to maintain, an investment-grade credit rating, and our generation business cannot always obtain government 
guarantees and if they do, the government does not always have an investment grade credit rating. We have also 
sought to reduce our credit risk by locating our plants in different geographic areas in order to mitigate the effects of 
regional economic downturns. However, there can be no assurance that our efforts to mitigate this risk will be 
successful.

Competition is increasing and could adversely affect us.

The power production markets in which we operate are characterized by numerous strong and capable 
competitors, many of whom may have extensive and diversified developmental or operating experience (including 
both domestic and international) and financial resources similar to or greater than ours. Further, in recent years, the 
power production industry has been characterized by strong and increasing competition with respect to both 
obtaining power sales agreements and acquiring existing power generation assets. In certain markets, these factors 
have caused reductions in prices contained in new power sales agreements and, in many cases, have caused 
higher acquisition prices for existing assets through competitive bidding practices. The evolution of competitive 
electricity markets and the development of highly efficient gas-fired power plants have also caused, or are 
anticipated to cause, price pressure in certain power markets where we sell or intend to sell power. These 
competitive factors could have a material adverse effect on us.

Some of our subsidiaries participate in defined benefit pension plans and their net pension plan 

obligations may require additional significant contributions.

Certain of our subsidiaries have defined benefit pension plans covering substantially all of their respective 
employees. Of the thirty one such defined benefit plans, five are at U.S. subsidiaries and the remaining plans are at 
foreign subsidiaries. Pension costs are based upon a number of actuarial assumptions, including an expected long-
term rate of return on pension plan assets, the expected life span of pension plan beneficiaries and the discount 
rate used to determine the present value of future pension obligations. Any of these assumptions could prove to be 
wrong, resulting in a shortfall of pension plan assets compared to pension obligations under the pension plan. The 
Company periodically evaluates the value of the pension plan assets to ensure that they will be sufficient to fund the 
respective pension obligations. The Company's exposure to market volatility is mitigated to some extent due to the 
fact that the asset allocations in our largest plans include a significant weighting of investments in fixed income 
securities that are less volatile than investments in equity securities. Future downturns in the debt and/or equity 
markets, or the inaccuracy of any of our significant assumptions underlying the estimates of our subsidiaries' 
pension plan obligations, could result in an increase in pension expense and future funding requirements, which 
may be material. Our subsidiaries who participate in these plans are responsible for satisfying the funding 
requirements required by law in their respective jurisdiction for any shortfall of pension plan assets compared to 
pension obligations under the pension plan. This may necessitate additional cash contributions to the pension plans 
that could adversely affect the Parent Company and our subsidiaries' liquidity.

For additional information regarding the funding position of the Company's pension plans, see Item 7.—

Management's Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting 
Policies and Estimates—Pension and Other Postretirement Plans and Note 15—Benefit Plans included in Item 8.—
Financial Statements and Supplementary Data included in this Form 10-K.

65

Our business is subject to substantial development uncertainties.

Certain of our subsidiaries and affiliates are in various stages of developing and constructing power plants, 

some but not all of which have signed long-term contracts or made similar arrangements for the sale of electricity. 
Successful completion depends upon overcoming substantial risks, including, but not limited to, risks relating to 
siting, financing, engineering and construction, permitting, governmental approvals, commissioning delays, or the 
potential for termination of the power sales contract as a result of a failure to meet certain milestones. For additional 
information regarding our projects under construction see Item 1.—Business—Our Organization and Segments 
included in this Form 10-K. 

In certain cases, our subsidiaries may enter into obligations in the development process even though the 

subsidiaries have not yet secured financing, power purchase arrangements, or other aspects of the development 
process. For example, in certain cases, our subsidiaries may instruct contractors to begin the construction process 
or seek to procure equipment even where they do not have financing or a power purchase agreement in place (or 
conversely, to enter into a power purchase, procurement or other agreement without financing in place). If the 
project does not proceed, our subsidiaries may remain obligated for certain liabilities even though the project will 
not proceed. Development is inherently uncertain and we may forgo certain development opportunities and we may 
undertake significant development costs before determining that we will not proceed with a particular project. We 
believe that capitalized costs for projects under development are recoverable; however, there can be no assurance 
that any individual project will be completed and reach commercial operation. If these development efforts are not 
successful, we may abandon a project under development and write off the costs incurred in connection with such 
project. At the time of abandonment, we would expense all capitalized development costs incurred in connection 
therewith and could incur additional losses associated with any related contingent liabilities.

In some of our joint venture projects and businesses, we have granted protective rights to minority 

shareholders or we own less than a majority of the equity in the project or business and do not manage or 
otherwise control the project or business, which entails certain risks.

We have invested in some joint ventures where our subsidiaries share operational, management, investment 

and/or other control rights with our joint venture partners. In many cases, we may exert influence over the joint 
venture pursuant to a management contract, by holding positions on the board of the joint venture company or on 
management committees and/or through certain limited governance rights, such as rights to veto significant actions. 
However, we do not always have this type of influence over the project or business in every instance and we may 
be dependent on our joint venture partners or the management team of the joint venture to operate, manage, invest 
or otherwise control such projects or businesses. Our joint venture partners or the management team of our joint 
ventures may not have the level of experience, technical expertise, human resources, management and other 
attributes necessary to operate these projects or businesses optimally, and they may not share our business 
priorities. In some joint venture agreements where we do have majority control of the voting securities, we have 
entered into shareholder agreements granting protective minority rights to the other shareholders. 

The approval of joint venture partners also may be required for us to receive distributions of funds from jointly 

owned entities or to transfer our interest in projects or businesses. The control or influence exerted by our joint 
venture partners may result in operational management and/or investment decisions which are different from the 
decisions our subsidiaries would make if they operated independently and could impact the profitability and value of 
these joint ventures. In addition, in the event that a joint venture partner becomes insolvent or bankrupt or is 
otherwise unable to meet its obligations to the joint venture or its share of liabilities at the joint venture, we may be 
subject to joint and several liability for these joint ventures, if and to the extent provided for in our governing 
documents or applicable law. 

Our renewable energy projects and other initiatives face considerable uncertainties including, 

development, operational and regulatory challenges.

Wind generation, our solar projects and our investments in projects such as energy storage are subject to 
substantial risks. Projects of this nature have been developed through advancement in technologies which may not 
be proven or whose commercial application is limited, and which are unrelated to our core business. Some of these 
business lines are dependent upon favorable regulatory incentives to support continued investment, and there is 
significant uncertainty about the extent to which such favorable regulatory incentives will be available in the future.

Furthermore, production levels for our wind and solar projects may be dependent upon adequate wind or 
sunlight resulting in volatility in production levels and profitability. For example, for our wind projects, wind resource 
estimates are based on historical experience when available and on wind resource studies conducted by an 
independent engineer, and are not expected to reflect actual wind energy production in any given year. 

66

As a result, these types of renewable energy projects face considerable risk relative to our core business, 
including the risk that favorable regulatory regimes expire or are adversely modified. In addition, because certain of 
these projects depend on technology outside of our expertise in generation and utility businesses, there are risks 
associated with our ability to develop and manage such projects profitably. Furthermore, at the development or 
acquisition stage, because of the nascent nature of these industries or the limited experience with the relevant 
technologies, our ability to predict actual performance results may be hindered and the projects may not perform as 
predicted. There are also risks associated with the fact that some of these projects exist in markets where long-term 
fixed price contracts for the major cost and revenue components may be unavailable, which in turn may result in 
these projects having relatively high levels of volatility. Even where available, many of our renewable projects sell 
power under a Feed-in-Tariff, which may be eliminated or reduced, which can impact the profitability of these 
projects, or make money through the sale of Emission Reductions products, such as Certified Emissions 
Reductions, Renewable Energy Certificates or Renewable Obligation Certificates, and the price of these products 
may be volatile. These projects can be capital-intensive and generally are designed with a view to obtaining third 
party financing, which may be difficult to obtain. As a result, these capital constraints may reduce our ability to 
develop these projects or obtain third party financing for these projects. 

Impairment of goodwill or long-lived assets would negatively impact our consolidated results of 

operations and net worth.

As of December 31, 2016, the Company had approximately $1.2 billion of goodwill, which represented 
approximately 3.2% of the total assets on its Consolidated Balance Sheets. Goodwill is not amortized, but is 
evaluated for impairment at least annually, or more frequently if impairment indicators are present. We may be 
required to evaluate the potential impairment of goodwill outside of the required annual evaluation process if we 
experience situations, including but not limited to: deterioration in general economic conditions, or our operating or 
regulatory environment; increased competitive environment; increase in fuel costs, particularly when we are unable 
to pass through the impact to customers; negative or declining cash flows; loss of a key contract or customer, 
particularly when we are unable to replace it on equally favorable terms; divestiture of a significant component of 
our business; or adverse actions or assessments by a regulator. These types of events and the resulting analyses 
could result in goodwill impairment, which could substantially affect our results of operations for those periods. 
Additionally, goodwill may be impaired if our acquisitions do not perform as expected. See the risk factor Our 
acquisitions may not perform as expected for further discussion.

Long-lived assets are initially recorded at fair value and are amortized or depreciated over their estimated 

useful lives. Long-lived assets are evaluated for impairment only when impairment indicators, similar to those 
described above for goodwill, are present, whereas goodwill is also evaluated for impairment on an annual basis.

Certain of our businesses are sensitive to variations in weather.

Our businesses are affected by variations in general weather patterns and unusually severe weather. Our 
businesses forecast electric sales on the basis of normal weather, which represents a long-term historical average. 
While we also consider possible variations in normal weather patterns and potential impacts on our facilities and our 
businesses, there can be no assurance that such planning can prevent these impacts, which can adversely affect 
our business. Generally, demand for electricity peaks in winter and summer. Typically, when winters are warmer 
than expected and summers are cooler than expected, demand for energy is lower, resulting in less demand for 
electricity than forecasted. Significant variations from normal weather where our businesses are located could have 
a material impact on our results of operations.

In addition, we are dependent upon hydrological conditions prevailing from time to time in the broad 
geographic regions in which our hydroelectric generation facilities are located. If hydrological conditions result in 
droughts or other conditions that negatively affect our hydroelectric generation business, our results of operations 
could be materially adversely affected.

Information security breaches could harm our business.

A security breach of our information technology systems or plant control systems used to manage and monitor 

operations could impact the reliability of our generation fleets and/or the reliability of our transmission and 
distribution systems. A security breach that impairs our technology infrastructure could disrupt normal business 
operations and affect our ability to control our transmission and distribution assets, access customer information 
and limit our communications with third parties. Our security measures may not prevent such security breaches. 
Any loss or corruption of confidential or proprietary data through a breach could impair our reputation, expose us to 
legal claims, or impact our ability to make collections or otherwise impact our operations, and materially adversely 
affect our business and results of operations.

67

Our acquisitions may not perform as expected.

Historically, acquisitions have been a significant part of our growth strategy. We may continue to grow our 
business through acquisitions. Although acquired businesses may have significant operating histories, we will have 
a limited or no history of owning and operating many of these businesses and possibly limited or no experience 
operating in the country or region where these businesses are located. Some of these businesses may have been 
government owned and some may be operated as part of a larger integrated utility prior to their acquisition. If we 
were to acquire any of these types of businesses, there can be no assurance that:

•  we will be successful in transitioning them to private ownership;

•  such businesses will perform as expected;
• 

integration or other one-time costs will not be greater than expected;

•  we will not incur unforeseen obligations or liabilities;
•  such businesses will generate sufficient cash flow to support the indebtedness incurred to acquire them or the 

capital expenditures needed to develop them; or

• 

the rate of return from such businesses will justify our decision to invest capital to acquire them.

Risks associated with Governmental Regulation and Laws

Our operations are subject to significant government regulation and our business and results of 

operations could be adversely affected by changes in the law or regulatory schemes.

Our ability to predict, influence or respond appropriately to changes in law or regulatory schemes, including 
any ability to obtain expected or contracted increases in electricity tariff or contract rates or tariff adjustments for 
increased expenses, could adversely impact our results of operations or our ability to meet publicly announced 
projections or analysts' expectations. Furthermore, changes in laws or regulations or changes in the application or 
interpretation of regulatory provisions in jurisdictions where we operate, particularly at our utilities where electricity 
tariffs are subject to regulatory review or approval, could adversely affect our business, including, but not limited to:

•  changes in the determination, definition or classification of costs to be included as reimbursable or pass-through 
costs to be included in the rates we charge our customers, including but not limited to costs incurred to upgrade 
our power plants to comply with more stringent environmental regulations;

•  changes in the determination of what is an appropriate rate of return on invested capital or a determination that a 

utility's operating income or the rates it charges customers are too high, resulting in a reduction of rates or 
consumer rebates;

•  changes in the definition or determination of controllable or non-controllable costs;
•  adverse changes in tax law;
•  changes in law or regulation which limit or otherwise affect the ability of our counterparties (including sovereign 

or private parties) to fulfill their obligations (including payment obligations) to us or our subsidiaries;

•  changes in environmental law which impose additional costs or limit the dispatch of our generating facilities 

within our subsidiaries;

•  changes in the definition of events which may or may not qualify as changes in economic equilibrium;

•  changes in the timing of tariff increases;

•  other changes in the regulatory determinations under the relevant concessions; 

•  other changes related to licensing or permitting which affect our ability to conduct business; or

•  other changes that impact the short or long term price-setting mechanism in the markets where we operate.

Any of the above events may result in lower margins for the affected businesses, which can adversely affect 

our business.

In many countries where we conduct business, the regulatory environment is constantly changing and it may 

be difficult to predict the impact of the regulations on our businesses. On July 21, 2010, President Obama signed 
the Dodd-Frank Act. While the bulk of regulations contained in the Dodd-Frank Act regulate financial institutions and 
their products, there are several provisions related to corporate governance, executive compensation, disclosure 
and other matters which relate to public companies generally. The types of provisions described above are currently 
not expected to have a material impact on the Company or its results of operations. Furthermore, while the Dodd-
Frank Act substantially expands the regulation regarding the trading, clearing and reporting of derivative 
transactions, the Dodd-Frank Act provides for commercial end-user exemptions which may apply to our derivative 
transactions. However, even with the exemption, the Dodd-Frank Act could still have a material adverse impact on 

68

the Company, as the regulation of derivatives (which includes capital and margin requirements for non-exempt 
companies), could limit the availability of derivative transactions that we use to reduce interest rate, commodity and 
currency risks, which would increase our exposure to these risks. Even if derivative transactions remain available, 
the costs to enter into these transactions may increase, which could adversely (1) affect the operating results of 
certain projects; (2) cause us to default on certain types of contracts where we are contractually obligated to hedge 
certain risks, such as project financing agreements; (3) prevent us from developing new projects where interest rate 
hedging is required; (4) cause the Company to abandon certain of its hedging strategies and transactions, thereby 
increasing our exposure to interest rate, commodity and currency risk; (5) and/or consume substantial liquidity by 
forcing the Company to post cash and/or other permitted collateral in support of these derivatives. In addition to the 
Dodd-Frank Act, in 2012, the EMIR became effective. EMIR includes regulations related to the trading, reporting 
and clearing of derivatives and the impacts described above could also result from our (or our subsidiaries') efforts 
to comply with EMIR. It is also possible that additional similar regulations may be passed in other jurisdictions 
where we conduct business. Any of these outcomes could have a material adverse effect on the Company.

Our business in the United States is subject to the provisions of various laws and regulations 

administered in whole or in part by the FERC and NERC, including PURPA, the Federal Power Act, and the 
EPAct 2005. Actions by the FERC, NERC and by state utility commissions can have a material effect on our 
operations.

EPAct 2005 authorizes the FERC to remove the obligation of electric utilities under Section 210 of PURPA to 
enter into new contracts for the purchase or sale of electricity from or to QFs if certain market conditions are met. 
Pursuant to this authority, the FERC has instituted a rebuttable presumption that utilities located within the control 
areas of the Midwest Independent Transmission System Operator, Inc., PJM Interconnection, L.L.C., ISO New 
England, Inc., the NYISO and the Electric Reliability Council of Texas, Inc. are not required to purchase or sell 
power from or to QFs above a certain size. In addition, the FERC is authorized under EPAct 2005 to remove the 
purchase/sale obligations of individual utilities on a case-by-case basis. While this law does not affect existing 
contracts, as a result of the changes to PURPA, our QFs may face a more difficult market environment when their 
current long-term contracts expire.

EPAct 2005 repealed PUHCA 1935 and enacted PUHCA 2005 in its place. PUHCA 1935 had the effect of 
requiring utility holding companies to operate in geographically proximate regions and therefore limited the range of 
potential combinations and mergers among utilities. By comparison, PUHCA 2005 has no such restrictions and 
simply provides the FERC and state utility commissions with enhanced access to the books and records of certain 
utility holding companies. The repeal of PUHCA 1935 removed barriers to mergers and other potential combinations 
which could result in the creation of large, geographically dispersed utility holding companies. These entities may 
have enhanced financial strength and therefore an increased ability to compete with us in the U.S. generation 
market.

In accordance with Congressional mandates in the EPAct 1992 and now in EPAct 2005, the FERC has 
strongly encouraged competition in wholesale electric markets. Increased competition may have the effect of 
lowering our operating margins. Among other steps, the FERC has encouraged RTOs and ISOs to develop demand 
response bidding programs as a mechanism for responding to peak electric demand. These programs may reduce 
the value of our peaking assets which rely on very high prices during a relatively small number of hours to recover 
their costs. Similarly, the FERC is encouraging the construction of new transmission infrastructure in accordance 
with provisions of EPAct 2005. Although new transmission lines may increase market opportunities, they may also 
increase the competition in our existing markets.

While the FERC continues to promote competition, some state utility commissions have reversed course and 
begun to encourage the construction of generation facilities by traditional utilities to be paid for on a cost-of-service 
basis by retail ratepayers. Such actions have the effect of reducing sale opportunities in the competitive wholesale 
generating markets in which we operate.

FERC has civil penalty authority over violations of any provision of Part II of the FPA which concerns 

wholesale generation or transmission, as well as any rule or order issued thereunder. FERC is authorized to assess 
a maximum civil penalty of $1 million per violation for each day that the violation continues. The FPA also provides 
for the assessment of criminal fines and imprisonment for violations under the FPA. This penalty authority was 
enhanced in EPAct 2005. With this expanded enforcement authority, violations of the FPA and FERC's regulations 
could potentially have more serious consequences than in the past.

Pursuant to EPAct 2005, the NERC has been certified by FERC as the Electric Reliability Organization 
("ERO") to develop mandatory and enforceable electric system reliability standards applicable throughout the U.S. 
to improve the overall reliability of the electric grid. These standards are subject to FERC review and approval. 

69

Once approved, the reliability standards may be enforced by FERC independently, or, alternatively, by the ERO and 
regional reliability organizations with responsibility for auditing, investigating and otherwise ensuring compliance 
with reliability standards, subject to FERC oversight. Monetary penalties of up to $1 million per day per violation 
may be assessed for violations of the reliability standards.

Our utility businesses in the U.S. face significant regulation by their respective state utility commissions. The 

regulatory discretion is reasonably broad in both Indiana and Ohio and includes regulation as to services and 
facilities, the valuation of property, the construction, purchase, or lease of electric generating facilities, the 
classification of accounts, rates of depreciation, the increase or decrease in retail rates and charges, the issuance 
of certain securities, the acquisition and sale of some public utility properties or securities and certain other matters. 
These businesses face the risk of unexpected or adverse regulatory action which could have a material adverse 
effect on our results of operations, financial condition, and cash flows. See Item 1.—Business—US SBU—U.S. 
Businesses—U.S. Utilities for further information on the regulation faced by our U.S. utilities. 

Our businesses are subject to stringent environmental laws and regulations.

Our businesses are subject to stringent environmental laws and regulations by many federal, regional, state 

and local authorities, international treaties and foreign governmental authorities. These laws and regulations 
generally concern emissions into the air, effluents into the water, use of water, wetlands preservation, remediation of 
contamination, waste disposal, endangered species and noise regulation, among others. Failure to comply with 
such laws and regulations or to obtain or comply with any necessary environmental permits pursuant to such laws 
and regulations could result in fines or other sanctions. Environmental laws and regulations affecting power 
generation and distribution are complex and have tended to become more stringent over time. Congress and other 
domestic and foreign governmental authorities have either considered or implemented various laws and regulations 
to restrict or tax certain emissions, particularly those involving air emissions and water discharges. See the various 
descriptions of these laws and regulations contained in Item 1.—Business of this Form 10-K. These laws and 
regulations have imposed, and proposed laws and regulations could impose in the future, additional costs on the 
operation of our power plants. We have incurred and will continue to incur significant capital and other expenditures 
to comply with these and other environmental laws and regulations. Changes in, or new development of, 
environmental restrictions may force the Company to incur significant expenses or expenses that may exceed our 
estimates. There can be no assurance that we would be able to recover all or any increased environmental costs 
from our customers or that our business, financial condition, including recorded asset values or results of 
operations, would not be materially and adversely affected by such expenditures or any changes in domestic or 
foreign environmental laws and regulations.

Our businesses are subject to enforcement initiatives from environmental regulatory agencies.

The EPA has pursued an enforcement initiative against coal-fired generating plants alleging wide-spread 
violations of the new source review and prevention of significant deterioration provisions of the CAA. The EPA has 
brought suit against a number of companies and has obtained settlements with many of these companies over such 
allegations. The allegations typically involve claims that a company made major modifications to a coal-fired 
generating unit without proper permit approval and without installing best available control technology. The 
principal, but not exclusive, focus of this EPA enforcement initiative is emissions of SO2 and NOx. In connection with 
this enforcement initiative, the EPA has imposed fines and required companies to install improved pollution control 
technologies to reduce emissions of SO2 and NOx. There can be no assurance that foreign environmental 
regulatory agencies in countries in which our subsidiaries operate will not pursue similar enforcement initiatives 
under relevant laws and regulations.

Regulators, politicians, non-governmental organizations and other private parties have expressed 
concern about greenhouse gas, or GHG, emissions and the potential risks associated with climate change 
and are taking actions which could have a material adverse impact on our consolidated results of 
operations, financial condition and cash flows.

As discussed in Item 1.—Business, at the international, federal and various regional and state levels, rules are 

in effect and policies are under development to regulate GHG emissions, thereby effectively putting a cost on such 
emissions in order to create financial incentives to reduce them. In 2016, the Company's subsidiaries operated 
businesses which had total CO2 emissions of approximately 67.7 million metric tonnes, approximately 30.2 million 
of which were emitted by businesses located in the U.S. (both figures ownership adjusted). The Company uses CO2 
emission estimation methodologies supported by "The Greenhouse Gas Protocol" reporting standard on GHG 
emissions. For existing power generation plants, CO2 emissions data are either obtained directly from plant 
continuous emission monitoring systems or calculated from actual fuel heat inputs and fuel type CO2 emission 
factors. The estimated annual CO2 emissions from fossil fuel electric power generation facilities of the Company's 

70

subsidiaries that are in construction or development and have received the necessary air permits for commercial 
operations are approximately 7.7 million metric tonnes (ownership adjusted). This overall estimate is based on a 
number of projections and assumptions that may prove to be incorrect, such as the forecasted dispatch, anticipated 
plant efficiency, fuel type, CO2 emissions rates and our subsidiaries' achieving completion of such construction and 
development projects. However, it is certain that the projects under construction or development when completed 
will increase emissions of our portfolio and therefore could increase the risks associated with regulation of GHG 
emissions. Because there is significant uncertainty regarding these estimates, actual emissions from these projects 
under construction or development may vary substantially from these estimates.

The non-utility, generation subsidiaries of the Company often seek to pass on any costs arising from CO2 
emissions to contract counterparties, but there can be no assurance that such subsidiaries of the Company will 
effectively pass such costs onto the contract counterparties or that the cost and burden associated with any dispute 
over which party bears such costs would not be burdensome and costly to the relevant subsidiaries of the 
Company. The utility subsidiaries of the Company may seek to pass on any costs arising from CO2 emissions to 
customers, but there can be no assurance that such subsidiaries of the Company will effectively pass such costs to 
the customers, or that they will be able to fully or timely recover such costs.

Foreign, federal, state or regional regulation of GHG emissions could have a material adverse impact on the 

Company's financial performance. The actual impact on the Company's financial performance and the financial 
performance of the Company's subsidiaries will depend on a number of factors, including among others, the degree 
and timing of GHG emissions reductions required under any such legislation or regulation, the cost of emissions 
reduction equipment and the price and availability of offsets, the extent to which market based compliance options 
are available, the extent to which our subsidiaries would be entitled to receive GHG emissions allowances without 
having to purchase them in an auction or on the open market and the impact of such legislation or regulation on the 
ability of our subsidiaries to recover costs incurred through rate increases or otherwise. As a result of these factors, 
our cost of compliance could be substantial and could have a material adverse impact on our results of operations.

In January 2005, based on European Community "Directive 2003/87/EC on Greenhouse Gas Emission 
Allowance Trading," the EU ETS commenced operation as the largest multi-country GHG emission trading scheme 
in the world. On February 16, 2005, the Kyoto Protocol became effective. The Kyoto Protocol requires all developed 
countries that have ratified it to substantially reduce their GHG emissions, including CO2. However, the United 
States never ratified the Kyoto Protocol and, to date, compliance with the Kyoto Protocol and the EU ETS has not 
had a material adverse effect on the Company's consolidated results of operations, financial condition and cash 
flows.

In December 2015, the Parties to the United Nations Framework Convention on Climate Change ("UNFCCC") 

convened for the 21st Conference of the Parties in Paris, France. The result was the so-called Paris Agreement. 
The Paris Agreement has a long-term goal of keeping the increase in global average temperature to well below 2°C 
above pre-industrial levels. In furtherance of this goal, participating countries submitted comprehensive national 
climate action plans and have agreed to meet every five years to set more ambitious targets as required by science, 
to report to each other and the public on how well they are doing to implement their targets and to track progress 
towards the long-term goal through a robust transparency and accountability system. We anticipate that the Paris 
Agreement will continue the trend towards the efforts to de-carbonize the global economy and to further limit GHG 
emissions, including in those countries where the Company does business. It is difficult to predict the nature, timing 
and scope of such regulation but it could have a material adverse effect on the Company's financial performance.

In the U.S., there currently is no federal legislation imposing a mandatory GHG emission reduction programs 

(including for CO2) affecting the electric power generation facilities of the Company's subsidiaries. However, the 
EPA has adopted regulations pertaining to GHG emissions that require new sources of GHG emissions of over 
100,000 tons per year, and existing sources planning physical changes that would increase their GHG emissions by 
more than 75,000 tons per year, to obtain new source review permits from the EPA prior to construction or 
modification. Additionally, the EPA has promulgated a rule establishing New Source Performance Standards for CO2 
emissions for newly constructed and modified/reconstructed fossil-fueled EUSGUs larger than 25 MW. The EPA 
has also promulgated a rule, the CPP, which requires existing EUSGUs to begin reducing GHG emissions starting 
in 2022 with the full reduction requirement in 2030. Under the CPP, states are required to develop and submit plans 
that establish performance standards or, through emissions trading programs, otherwise meet a state-wide 
emissions rate average or mass-based goal. For further discussion of the regulation of GHG emission, including the 
U.S. Supreme Court's issued an order staying implementation of the CPP, see Item 1.—Business—Environmental 
and Land-Use Regulations—United States Environmental and Land-Use Legislation and Regulations—Greenhouse 
Gas Emissions above.

71

Such regulations, and in particular regulations applying to modified or existing EUSGUs, could increase our 
costs directly and indirectly and have a material adverse effect on our business and/or results of operations. See 
Item 1.—Business of this Form 10-K for further discussion about these environmental agreements, laws and 
regulations.

At the state level, the RGGI, a cap-and-trade program covering CO2 emissions from electric power generation 
facilities in the Northeast, became effective in January 2009, and California has adopted comprehensive legislation 
and regulation that requires GHG reductions from multiple industrial sectors, including the electric power generation 
industry. At this time, other than with regard to RGGI (further described below) and proposed Hawaii regulations 
relating to the collection of fees on GHG emissions, the impact of both of which we do not expect to be material, the 
Company cannot estimate the costs of compliance with U.S. federal, regional or state GHG emissions reduction 
legislation or initiatives, due to the fact that most of these proposals are not being actively pursued or are in the 
early stages of development and any final regulations or laws, if adopted, could vary drastically from current 
proposals; in the case of California, we anticipate no material impact due to the fact that we expect such costs will 
be passed through to our offtakers under the terms of existing tolling agreements.

The auctions of RGGI allowances needed by power generators to comply with state programs implementing 

RGGI occur approximately every quarter. Our subsidiary in Maryland is our only subsidiary that was subject to 
RGGI in 2016. Of the approximately 30.2 million metric tonnes of CO2 emitted in the United States by our 
subsidiaries in 2016 (ownership adjusted), approximately 1.1 million metric tonnes were emitted by our subsidiary in 
Maryland. The Company estimates that the RGGI compliance costs could be approximately $3.2 million for 2017. 
There is a risk that our actual compliance costs under RGGI will differ from our estimates by a material amount and 
that our model could underestimate our costs of compliance.

In addition to government regulators, other groups such as politicians, environmentalists and other private 

parties have expressed increasing concern about GHG emissions. For example, certain financial institutions have 
expressed concern about providing financing for facilities which would emit GHGs, which can affect our ability to 
obtain capital, or if we can obtain capital, to receive it on commercially viable terms. Further, rating agencies may 
decide to downgrade our credit ratings based on the emissions of the businesses operated by our subsidiaries or 
increased compliance costs which could make financing unattractive. In addition, plaintiffs have brought tort 
lawsuits against the Company because of its subsidiaries' GHG emissions. While the litigation mentioned has been 
dismissed, it is impossible to predict whether similar future lawsuits are likely to prevail or result in damages awards 
or other relief. Consequently, it is impossible to determine whether such lawsuits are likely to have a material 
adverse effect on the Company's consolidated results of operations and financial condition.

Furthermore, according to the Intergovernmental Panel on Climate Change, physical risks from climate 
change could include, but are not limited to, increased runoff and earlier spring peak discharge in many glacier and 
snow-fed rivers, warming of lakes and rivers, an increase in sea level, changes and variability in precipitation and in 
the intensity and frequency of extreme weather events. Physical impacts may have the potential to significantly 
affect the Company's business and operations, and any such potential impact may render it more difficult for our 
businesses to obtain financing. For example, extreme weather events could result in increased downtime and 
operation and maintenance costs at the electric power generation facilities and support facilities of the Company's 
subsidiaries. Variations in weather conditions, primarily temperature and humidity also would be expected to affect 
the energy needs of customers. A decrease in energy consumption could decrease the revenues of the Company's 
subsidiaries. In addition, while revenues would be expected to increase if the energy consumption of customers 
increased, such increase could prompt the need for additional investment in generation capacity. Changes in the 
temperature of lakes and rivers and changes in precipitation that result in drought could adversely affect the 
operations of the fossil fuel-fired electric power generation facilities of the Company's subsidiaries. Changes in 
temperature, precipitation and snow pack conditions also could affect the amount and timing of hydroelectric 
generation.

In addition to potential physical risks noted by the Intergovernmental Panel on Climate Change, there could be 

damage to the reputation of the Company and its subsidiaries due to public perception of GHG emissions by the 
Company's subsidiaries, and any such negative public perception or concerns could ultimately result in a decreased 
demand for electric power generation or distribution from our subsidiaries. The level of GHG emissions made by 
subsidiaries of the Company is not a factor in the compensation of executives of the Company.

If any of the foregoing risks materialize, costs may increase or revenues may decrease and there could be a 

material adverse effect on the electric power generation businesses of the Company's subsidiaries and on the 
Company's consolidated results of operations, financial condition and cash flows.

72

Tax legislation initiatives or challenges to our tax positions could adversely affect our results of 

operations and financial condition.

Our subsidiaries have operations in the U.S. and various non-U.S. jurisdictions. As such, we are subject to the 
tax laws and regulations of the U.S. federal, state and local governments and of many non-U.S. jurisdictions. From 
time to time, legislative measures may be enacted that could adversely affect our overall tax positions regarding 
income or other taxes. There can be no assurance that our effective tax rate or tax payments will not be adversely 
affected by these legislative measures. 

For example, the U.S. is considering corporate tax reform that may significantly change corporate tax rates, 

business rules such as interest deductibility and capital expenditure cost recovery, and U.S. international tax rules. 
Additionally, longstanding international tax norms that determine how and where cross-border international trade is 
subjected to tax are evolving. The Organization for Economic Cooperation and Development ("OECD"), in 
coordination with the G8 and G20, through its Base Erosion and Profit Shifting project (“BEPS") introduced a series 
of recommendations that many tax jurisdictions have adopted, or may adopt in the future, as law. As these and 
other tax laws, related regulations and double-tax conventions change, our financial results could be materially 
impacted. Given the unpredictability of these possible changes and their potential interdependency, it is very difficult 
to assess whether the overall effect of such potential tax changes would be cumulatively positive or negative for our 
earnings and cash flow, but such changes could adversely impact our results of operations.

In addition, U.S. federal, state and local, as well as non-U.S., tax laws and regulations are extremely complex 

and subject to varying interpretations. There can be no assurance that our tax positions will be sustained if 
challenged by relevant tax authorities and if not sustained, there could be a material impact on our results of 
operations. 

We and our affiliates are subject to material litigation and regulatory proceedings.

We and our affiliates are parties to material litigation and regulatory proceedings. See Item 3.—Legal 

Proceedings below. There can be no assurances that the outcome of such matters will not have a material adverse 
effect on our consolidated financial position.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 2. PROPERTIES

We maintain offices in many places around the world, generally pursuant to the provisions of long- and short-

term leases, none of which we believe are material. With a few exceptions, our facilities, which are described in 
Item 1—Business of this Form 10-K, are subject to mortgages or other liens or encumbrances as part of the 
project's related finance facility. In addition, the majority of our facilities are located on land that is leased. However, 
in a few instances, no accompanying project financing exists for the facility, and in a few of these cases, the land 
interest may not be subject to any encumbrance and is owned outright by the subsidiary or affiliate.

ITEM 3. LEGAL PROCEEDINGS 

The Company is involved in certain claims, suits and legal proceedings in the normal course of business. The 
Company has accrued for litigation and claims where it is probable that a liability has been incurred and the amount 
of loss can be reasonably estimated. The Company believes, based upon information it currently possesses and 
taking into account established reserves for estimated liabilities and its insurance coverage, that the ultimate 
outcome of these proceedings and actions is unlikely to have a material adverse effect on the Company's financial 
statements. It is reasonably possible, however, that some matters could be decided unfavorably to the Company 
and could require the Company to pay damages or make expenditures in amounts that could be material but cannot 
be estimated as of December 31, 2016.

In 1989, Centrais Elétricas Brasileiras S.A. (“Eletrobrás”) filed suit in the Fifth District Court in the state of Rio 
de Janeiro (“FDC”) against Eletropaulo Eletricidade de São Paulo S.A. (“EEDSP”) relating to the methodology for 
calculating monetary adjustments under the parties' financing agreement. In April 1999, the FDC found in favor of 
Eletrobrás and in September 2001, Eletrobrás initiated an execution suit in the FDC to collect approximately R$2.0 
billion ($602 million) from Eletropaulo as estimated by Eletropaulo (or approximately R$2.6 billion ($802 million) as 
of September 2016, as estimated by Eletrobrás, and possibly legal costs) and a lesser amount from an unrelated 
company, Companhia de Transmissão de Energia Elétrica Paulista (“CTEEP”) (Eletropaulo and CTEEP were spun 
off of EEDSP pursuant to its privatization in 1998). In November 2002, the FDC rejected Eletropaulo's defenses in 
the execution suit. On appeal, the case was remanded to the FDC for further proceedings to determine whether 
Eletropaulo is liable for the debt. In December 2012, the FDC issued a decision that Eletropaulo is liable for the 

73

 
debt. However, that decision was annulled on appeal and the case was remanded to the FDC for further 
proceedings. On remand at the FDC, the FDC appointed an accounting expert to analyze the issues in the case. In 
September 2015, the expert issued a preliminary report concluding that Eletropaulo is liable for the debt, without 
quantifying the debt. Eletropaulo thereafter submitted questions to the expert and reports rebutting the expert's 
preliminary report. In April 2016, Eletrobrás requested that the expert determine both the criteria to calculate the 
debt and the amount of the debt. The FDC is considering whether the criteria can be determined by the expert or 
must be determined by the FDC. After that issue is resolved, the expert may issue a final report. Ultimately, a 
decision will be issued by the FDC, which will be free to reject or adopt in whole or in part the expert's report. If the 
FDC again determines that Eletropaulo is liable for the debt, Eletrobrás will be entitled to resume the execution suit 
in the FDC. If Eletrobrás does so, Eletropaulo will be required to provide security for its alleged liability. In addition, 
in February 2008, CTEEP filed a lawsuit in the FDC against Eletrobrás and Eletropaulo seeking a declaration that 
CTEEP is not liable for any debt under the financing agreement. Eletropaulo believes it has meritorious defenses to 
the claims asserted against it and will defend itself vigorously in these proceedings; however, there can be no 
assurances that it will be successful in its efforts. If Eletrobrás requests the seizure of the security noted above and 
the FDC grants such request (or if a court determines that Eletropaulo is liable for the debt), Eletropaulo's results of 
operations may be materially adversely affected and, in turn, the Company's results of operations may also be 
materially adversely affected. Eletropaulo and the Company could face a loss of earnings and/or cash flows and 
may have to provide loans or equity to support affected businesses or projects, restructure them, write down their 
value, and/or face the possibility that Eletropaulo cannot continue operations or provide returns consistent with our 
expectations, any of which could have a material impact on the Company.

In September 1996, a public civil action was asserted against Eletropaulo and Associação Desportiva Cultural 
Eletropaulo (the “Associação”) relating to alleged environmental damage caused by construction of the Associação 
near Guarapiranga Reservoir. The initial decision that was upheld by the Appellate Court of the state of São Paulo 
in 2006 found that Eletropaulo should repair the alleged environmental damage by demolishing certain construction 
and reforesting the area, and either sponsor an environmental project which would cost approximately R$2 million 
($614 thousand) as of December 31, 2015, or pay an indemnification amount of approximately R$15 million ($5 
million). Eletropaulo has appealed this decision to the Supreme Court and the Supreme Court affirmed the decision 
of the Appellate Court. Following the Supreme Court's decision, the case has been remanded to the court of first 
instance for further proceedings and to monitor compliance by the defendants with the terms of the decision. In 
January 2014, Eletropaulo informed the court that it intended to comply with the court's decision by donating a 
green area inside a protection zone and restore watersheds, the aggregate cost of which is expected to be 
approximately R$2 million ($614 thousand). Eletropaulo also requested that the court add the current owner of the 
land where the Associação facilities are located, Empresa Metropolitana de Águas e Energia S.A. (“EMAE”), as a 
party to the lawsuit and order EMAE to perform the demolition and reforestation aspects of the court's decision. In 
July 2014, the court requested the Secretary of the Environment for the State of São Paulo to notify the court of its 
opinion regarding the acceptability of the green areas to be donated by Eletropaulo to the State of São Paulo. In 
January 2015, the Secretary of the Environment for the State of São Paulo notified Eletropaulo and the court that it 
would not accept Eletropaulo's proposed green areas donation. Instead of such green areas donation, the 
Secretary of the Environment proposed in March 2015 that Eletropaulo undertake an environmental project to offset 
the alleged environmental damage. Since March 2015, Eletropaulo and the Secretary of Environment have been 
working together to define an environmental project, which will be submitted for approval by the Public 
Prosecutor. The cost of such project is currently estimated to be R$3 million ($1 million).

In December 2001, GRIDCO served a notice to arbitrate pursuant to the Indian Arbitration and Conciliation Act 

of 1996 on the Company, AES Orissa Distribution Private Limited (“AES ODPL”), and Jyoti Structures (“Jyoti”) 
pursuant to the terms of the shareholders agreement between GRIDCO, the Company, AES ODPL, Jyoti and the 
Central Electricity Supply Company of Orissa Ltd. (“CESCO”), an affiliate of the Company. In the arbitration, 
GRIDCO asserted that a comfort letter issued by the Company in connection with the Company's indirect 
investment in CESCO obligates the Company to provide additional financial support to cover all of CESCO's 
financial obligations to GRIDCO. GRIDCO appeared to be seeking approximately $189 million in damages, plus 
undisclosed penalties and interest, but a detailed alleged damage analysis was not filed by GRIDCO. The Company 
counterclaimed against GRIDCO for damages. In June 2007, a 2-to-1 majority of the arbitral tribunal rendered its 
award rejecting GRIDCO's claims and holding that none of the respondents, the Company, AES ODPL, or Jyoti, 
had any liability to GRIDCO. The respondents' counterclaims were also rejected. A majority of the tribunal later 
awarded the respondents, including the Company, some of their costs relating to the arbitration. GRIDCO filed 
challenges of the tribunal's awards with the local Indian court. GRIDCO's challenge of the costs award has been 
dismissed by the court, but its challenge of the liability award remains pending. The Company believes that it has 

74

meritorious defenses to the claims asserted against it and will defend itself vigorously in these proceedings; 
however, there can be no assurances that it will be successful in its efforts.

In March 2003, the office of the Federal Public Prosecutor for the State of São Paulo, Brazil (“MPF”) notified 

Eletropaulo that it had commenced an inquiry into the BNDES financings provided to AES Elpa and AES Transgás, 
the rationing loan provided to Eletropaulo, changes in the control of Eletropaulo, sales of assets by Eletropaulo, and 
the quality of service provided by Eletropaulo to its customers. The MPF requested various documents from 
Eletropaulo relating to these matters. In July 2004, the MPF filed a public civil lawsuit in the Federal Court of São 
Paulo (“FCSP”) alleging that BNDES violated Law 8429/92 (“the Administrative Misconduct Act”) and BNDES's 
internal rules by: (1) approving the AES Elpa and AES Transgás loans; (2) extending the payment terms on the AES 
Elpa and AES Transgás loans; (3) authorizing the sale of Eletropaulo's preferred shares at a stock-market auction; 
(4) accepting Eletropaulo's preferred shares to secure the loan provided to Eletropaulo; and (5) allowing the 
restructurings of Light Serviços de Eletricidade S.A. and Eletropaulo. The MPF also named AES Elpa and AES 
Transgás as defendants in the lawsuit because they allegedly benefited from BNDES's alleged violations. In May 
2006, the FCSP ruled that the MPF could pursue its claims based on the first, second, and fourth alleged violations 
noted above. The MPF subsequently filed an interlocutory appeal with the Federal Court of Appeals (“FCA”) 
seeking to require the FCSP to consider all five alleged violations. In April 2015, the FCA issued a decision holding 
that the FCSP should consider all five alleged violations. AES Elpa and AES Brasiliana (the successor of AES 
Transgás) have appealed the April 2015 decision to the Superior Court of Justice. The lawsuit remains pending 
before the FCSP. AES Elpa and AES Brasiliana believe they have meritorious defenses to the allegations asserted 
against them and will defend themselves vigorously in these proceedings; however, there can be no assurances 
that they will be successful in their efforts.

Pursuant to their environmental audit, AES Sul and AES Florestal discovered 200 barrels of solid creosote 
waste and other contaminants at a pole factory that AES Florestal had been operating. The conclusion of the audit 
was that a prior operator of the pole factory, Companhia Estadual de Energia (“CEEE”), had been using those 
contaminants to treat the poles that were manufactured at the factory. On their initiative, AES Sul and AES Florestal 
communicated with Brazilian authorities and CEEE about the adoption of containment and remediation measures. 
In March 2008, the State Attorney of the state of Rio Grande do Sul, Brazil filed a public civil action against AES 
Sul, AES Florestal and CEEE seeking an order requiring the companies to recover the contaminated area located 
on the grounds of the pole factory and an indemnity payment of approximately R$6 million ($2 million) to the state's 
Environmental Fund. In October 2011, the State Attorney Office filed a request for an injunction ordering the 
defendant companies to contain and remove the contamination immediately. The court granted injunctive relief on 
October 18, 2011, but determined only that defendant CEEE was required to proceed with the removal work. In May 
2012, CEEE began the removal work in compliance with the injunction. The removal costs are estimated to be 
approximately R$60 million ($18 million) and the work was completed in February 2014. In parallel with the removal 
activities, a court-appointed expert investigation took place, which was concluded in May 2014. The court-appointed 
expert final report was presented to the State Attorneys in October 2014, and in January 2015 to the defendant 
companies. In March 2015, AES Sul and AES Florestal submitted comments and supplementary questions 
regarding the expert report. The Company believes that it has meritorious defenses to the claims asserted against it 
and will defend itself vigorously in these proceedings; however, there can be no assurances that it will be successful 
in its efforts.

In March 2009, AES Uruguaiana Empreendimentos S.A. (“AESU”) in Brazil initiated arbitration against YPF 

S.A. (“YPF”) seeking damages and other relief relating to YPF's breach of the parties' gas supply agreement 
(“GSA”). Thereafter, in April 2009, YPF initiated arbitration against AESU and two unrelated parties, Companhia de 
Gas do Estado do Rio Grande do Sul and Transportador de Gas del Mercosur S.A. (“TGM”), claiming that AESU 
wrongfully terminated the GSA and caused the termination of a transportation agreement (“TA”) between YPF and 
TGM (“YPF Arbitration”). YPF sought an unspecified amount of damages from AESU, a declaration that YPF's 
performance was excused under the GSA due to certain alleged force majeure events, or, in the alternative, a 
declaration that the GSA and the TA should be terminated without a finding of liability against YPF because of the 
allegedly onerous obligations imposed on YPF by those agreements. In addition, in the YPF Arbitration, TGM 
asserted that if AESU were found liable for terminating the GSA, AESU should also be found liable for TGM's 
alleged losses, under the TA. In April 2011, the arbitrations were consolidated into a single proceeding. In May 
2013, the arbitral tribunal issued an award finding YPF liable to AESU and TGM. Thereafter, in April 2016, the 
tribunal issued a damages award ordering YPF to pay damages to AESU and TGM. In January 2017, AESU and 
YPF settled their dispute.

In October 2009, IPL received a NOV and Finding of Violation from the EPA pursuant to the CAA Section 113

(a). The NOV alleges violations of the CAA at IPL's three primarily coal-fired electric generating facilities dating back 
to 1986. The alleged violations primarily pertain to the Prevention of Significant Deterioration and nonattainment 

75

New Source Review requirements under the CAA. IPL management previously met with EPA staff regarding 
possible resolutions of the NOV. At this time, we cannot predict the ultimate resolution of this matter. However, 
settlements and litigated outcomes of similar cases have required companies to pay civil penalties, install additional 
pollution control technology on coal-fired electric generating units, retire existing generating units, and invest in 
additional environmental projects. A similar outcome in this case could have a material impact to IPL and could, in 
turn, have a material impact on the Company. IPL would seek recovery of any operating or capital expenditures 
related to air pollution control technology to reduce regulated air emissions; however, there can be no assurances 
that it would be successful in that regard.

In June 2011, the São Paulo Municipal Tax Authority (the “Tax Authority”) filed 60 tax assessments in São 

Paulo administrative court against Eletropaulo, seeking to collect services tax (“ISS”) that allegedly had not been 
paid on revenues for services rendered by Eletropaulo. Eletropaulo challenged the assessments on the grounds 
that the revenues at issue were not subject to ISS. In October 2013, the First Instance Administrative Court (“FIAC”) 
determined that Eletropaulo was liable for ISS, interest, and related penalties totaling approximately R$3.3 billion 
($1.0 billion) as estimated by Eletropaulo. Eletropaulo thereafter appealed to the Second Instance Administrative 
Court (“SIAC”). In January 2016, the Tax Authority nullified most of the ISS sought from Eletropaulo.In January 
2017, the SIAC issued a decision confirming the reduction and rejecting certain other amounts of ISS as time-
barred, but finding that Eletropaulo was liable for the remainder of ISS totaling approximately R$200 million ($61 
million). The matter is on appeal before the Municipal Council of Taxes. Eletropaulo believes it has meritorious 
defenses and will defend itself vigorously in these proceedings; however, there can be no assurances that it will be 
successful in its efforts.

In January 2012, the Brazil Federal Tax Authority issued an assessment alleging that AES Tietê had paid PIS 

and COFINS taxes from 2007 to 2010 at a lower rate than the tax authority believed was applicable. AES Tietê 
challenged the assessment on the grounds that the tax rate was set in the applicable legislation. In April 2013, the 
FIAC determined that AES Tietê should have calculated the taxes at the higher rate and that AES Tietê was liable 
for unpaid taxes, interest, and penalties totaling approximately R$960 million ($295 million) as estimated by AES 
Tietê. AES Tietê appealed to the SIAC. In January 2015, the SIAC issued a decision in AES Tietê's favor, finding 
that AES Tietê was not liable for unpaid taxes. The public prosecutor subsequently filed an appeal, which was 
denied as untimely. The Tax Authority thereafter filed a motion for clarification of the SIAC's decision, which was 
denied in September 2016. The Tax Authority later filed a special appeal, but that appeal was rejected in October 
2017. The Tax Authority has filed an interlocutory appeal, which is pending. AES Tietê believes it has meritorious 
defenses to the claim and will defend itself vigorously in these proceedings; however, there can be no assurances 
that it will be successful in its efforts.

In January 2015, DPL received NOVs from the EPA alleging violations of opacity at Stuart and Killen Stations, 

and in October 2015, IPL received a similar NOV alleging violations at Petersburg Station. In February 2016, IPL 
received an NOV from the EPA alleging violations of New Source Review (“NSR”) and other CAA regulations, the 
Indiana SIP, and the Title V operating permit at Petersburg Station. It is too early to determine whether the NOVs 
could have a material impact on our business, financial condition or results of our operations. IPL would seek 
recovery of any operating or capital expenditures, but not fines or penalties, related to air pollution control 
technology to reduce regulated air emissions; however, there can be no assurances that we would be successful in 
this regard.

In September 2015, AES Southland Development, LLC and AES Redondo Beach, LLC filed a lawsuit against 
the California Coastal Commission (the “CCC”) over the CCC's determination that the site of AES Redondo Beach 
included approximately 5.93 acres of CCC-jurisdictional wetlands. The CCC has asserted that AES Redondo Beach 
has improperly installed and operated water pumps affecting the alleged wetlands in violation of the California 
Coastal Act and Redondo Beach Local Coastal Program and has ordered AES Redondo Beach to restore the site. 
Additional potential outcomes of the CCC determination could include an order requiring AES Redondo Beach to 
fund a wetland mitigation project and/or pay fines or penalties. AES Redondo Beach believes that it has meritorious 
arguments and intends to vigorously prosecute such lawsuit, but there can be no assurances that it will be 
successful.

In October 2015, Ganadera Guerra, S.A. (“GG”) and Constructora Tymsa, S.A. (“CT”) filed separate lawsuits 

against AES Panama in the local courts of Panama. The claimants allege that AES Panama profited from a 
hydropower facility (La Estrella) being partially located on land owned initially by GG and currently by CT, and that 
AES Panama must pay compensation for its use of the land. The damages sought from AES Panama are 
approximately $685 million (GG) and $100 million (CT). In October 2016, the court dismissed GG's claim because 
of GG's failure to comply with a court order requiring GG to disclose certain information. It is expected that GG will 
refile its lawsuit. Also, there are ongoing administrative proceedings concerning whether AES Panama is entitled to 

76

acquire an easement over the land and whether AES Panama can continue to occupy the land. AES Panama 
believes it has meritorious defenses and claims and will assert them vigorously; however, there can be no 
assurances that it will be successful in its efforts.

assurances as to the amount, timing or prices of repurchases, which may vary based on market conditions and 
other factors. The Program does not have an expiration date and can be modified or terminated by the Board of 
Directors at any time. During the year ended December 31, 2016, the Company repurchased 8.7 million shares of 
its common stock at a total cost of $79 million under the existing stock repurchase program. The cumulative 
repurchase from the commencement of the Program in July 2010 through December 31, 2016 is 154.3 million 
shares at a total cost of $1.9 billion, at an average price per share of $12.12 (including a nominal amount of 
commissions). As of December 31, 2016, $246 million remained available for repurchase under the Program.

No repurchases were made by The AES Corporation of its common stock during the fourth quarter of 2016.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 
OPERATIONS

Key Topics in Management's Discussion and Analysis

Our discussion covers the following:

•  Executive Summary

•  Overview of 2016 Results and Strategic Performance

•  Review of Consolidated Results of Operations

•  SBU Performance Analysis

•  Key Trends and Uncertainties

•  Capital Resources and Liquidity

Executive Summary 

Consolidated Net Cash Provided by Operating Activities for the year ended December 31, 2016 was $2,884 
million, an increase of $750 million compared to the year ended December 31, 2015. The increase was primarily 
driven by higher collections at the Company’s distribution business in Brazil, Eletropaulo and Sul, and the 
settlement of overdue receivables at Maritza in Bulgaria. These positive contributions were offset by lower margins 
across the SBUs (primarily due to lower wholesale prices and lower contributions from regulated customers in the 
U.S., lower contracted rates in Tietê, the prior year liability reversal in Eletropaulo and unfavorable FX in 
Kazakhstan), as well as the recovery of overdue receivables in the Dominican Republic in 2015, which benefited 

80

2015 results. Proportional Free Cash Flow (a non-GAAP financial measure) for the year ended December 31, 2016 
increased $176 million to $1,417 million compared to the year ended December 31, 2015, primarily due to the same 
factors as Consolidated Net Cash Provided by Operating Activities.

See reconciliation and definition under SBU Performance Analysis—Non-GAAP Measures. 
Disclosure of Proportional Free Cash Flow will be discontinued beginning in the first quarter of 2017. See further discussion under SBU Performance Analysis
—Non-GAAP Measures.

Diluted earnings per share from continuing operations decreased primarily due to higher impairment expense 

on long lived assets, lower gains on foreign currency derivatives, lower operating margins at our US, Brazil and 
Europe SBUs, and lower equity in earnings of affiliates due to the gain earned in 2015 from the restructuring of 
Guacolda; partially offset by a lower effective tax rate, the absence of goodwill impairment expense in the current 
year, lower losses on extinguishment of debt and lower share count.

Adjusted EPS, a non-GAAP measure, decreased by 22% to $0.98 primarily driven by lower operating margins 

at our US, Brazil, and Europe SBUs, lower equity in earnings of affiliates due to the gain earned in 2015 from the 
restructuring of Guacolda; partially offset by a lower adjusted effective tax rate and lower share count.

Net cash provided by operating activities increased by 35% to $2.9 billion primarily driven by an increase in 
collections at our Brazil utilities, the collection of overdue receivables at Maritza, and lower costs associated with 
the fulfillment of our service concession arrangement and lower working capital requirements at Mong Duong. 
These positive impacts were partially offset by the timing of payments at our Brazil utilities for higher energy 
purchases made in the prior year, collections of overdue receivables in the prior year in the Dominican Republic, 
and lower net income adjusted for non-cash items.

Proportional free cash flow, a non-GAAP measure, increased by 14% to $1.4 billion primarily driven by an 
increase in collections at our Brazil utilities, the collection of overdue receivables at Maritza, and lower working 
capital requirements at Mong Duong. These positive impacts were partially offset by the timing of payments at our 
Brazil utilities for higher energy purchases made in the prior year, collections of overdue receivables in the prior 
year in the Dominican Republic, and a decrease in Adjusted Operating Margin (a non-GAAP measure).

Components of Revenue, Cost of Sales and Operating Margin — Revenue includes revenue earned from the 

sale of energy from our utilities and the production of energy from our generation plants, which are classified as 
regulated and non-regulated, respectively, on the Consolidated Statements of Operations. Revenue also includes 
the gains or losses on derivatives associated with the sale of electricity. 

Cost of sales includes costs incurred directly by the businesses in the ordinary course of business. Examples 

include electricity and fuel purchases, operations & maintenance costs, depreciation and amortization expense, bad 
debt expense and recoveries, and general administrative and support costs (including employee-related costs 
directly associated with the operations of the business). Cost of sales also includes the gains or losses on 
derivatives (including embedded derivatives other than foreign currency embedded derivatives) associated with the 
purchase of electricity or fuel.

Operating margin is defined as revenue less cost of sales.

Consolidated Revenue and Operating Margin

(in millions)

Year Ended December 31, 2016

Consolidated Revenue — Revenue decreased in 2016 compared to 2015 primarily due to: 

•  Unfavorable FX impacts of $511 million, primarily in Brazil of $213 million, Argentina of $94 million, Kazakhstan 

of $63 million and Colombia of $54 million. 

•  Brazil due to lower rates for energy sold in Brazil under new contracts at Tietê; operations in 2015 but not in 

2016 at Uruguiana; the reversal of a contingent regulatory liability in 2015, and lower demand, partially offset by 
the annual tariff adjustment at Eletropaulo. 

•  Lower pass-through costs at El Salvador and IPP4 in Jordan, the sale of DPLER in January 2016, and lower 

rates at DPL. 

These decreases were partially offset by: 

•  The full operations at Mong Duong in 2016 compared to Unit 1 in March 2015 with principal operations 

commencing in April 2015

•  The commencement of operations at Cochrane in Chile with Unit 1 operational in July 2016 and principal 

operations in October). 

•  Higher environmental returns and new rate case at IPL.

Consolidated Operating Margin — Operating margin decreased in 2016 compared to 2015 primarily due to:

•  Unfavorable FX impacts of $80 million, primarily in Kazakhstan, Argentina, and Colombia. 
•  Brazil driven by the revenue drivers above as well as higher fixed costs at Eletropaulo. 

These decreases were partially offset by:

•  Higher margin at Gener, impact from full operations at Mong Duong in Vietnam and Cochrane in Chile, and 

higher margins at IPL as discussed above.

Year Ended December 31, 2015 

Consolidated Revenue — Revenue decreased in 2015 compared to 2014 primarily due to: 

•  Unfavorable FX impacts of $2.2 billion, mainly in Brazil of $1.8 billion, Colombia of $179 million, and Bulgaria of 

$74 million.

•  US Utilities due to lower volumes primarily at DPL and outages, milder weather, and lower demand at IPL. 

•  Lower prices in the Dominican Republic and El Salvador (primarily resulting from lower pass-through costs). 

These decreases were partially offset by: 

•  Brazil due to higher tariffs at Eletropaulo (including higher pass-through costs) and the reversal of a contingent 

regulatory liability at Eletropaulo. 

•  Higher capacity prices at DPL.

•  Commencement of principal operations at Mong Duong in April 2015.

83

Consolidated Operating Margin — Operating margin decreased in 2015 compared to 2014 primarily due to:

•  Unfavorable FX impacts of $362 million, primarily in Brazil of $228 million and Colombia of $83 million.

•  Brazil due to lower demand, lower hydrology, and higher fixed costs. 
•  The Dominican Republic due to lower prices and lower availability. 

These decreases were partially offset by:

•  Higher tariffs in Brazil as discussed above and lower spot prices on energy purchases at Tietê.

•  Higher generation and lower energy purchases driven by improved hydrological conditions in Panama. 
•  Higher prices at Chivor driven by a strong El Niño.

•  Higher availability at Gener and Masinloc. 

See Item 7.—SBU Performance Analysis of this Form 10-K for additional discussion and analysis of operating 

results for each SBU.

Consolidated Results of Operations — Other
General and administrative expenses

General and administrative expenses include expenses related to corporate staff functions and/or initiatives, 
executive management, finance, legal, human resources and information systems, as well as global development 
costs.

General and administrative expenses decreased in 2016 from 2015 primarily due to decreased employee-

related costs, partially offset by increased business development costs.

General and administrative expenses increased in 2015 from 2014 primarily due to increased business 

development costs and employee-related costs partially offset by decreased professional fees.

Interest expense

Interest expense increased in 2016 from 2015 primarily due to a $97 million increase at Eletropaulo as a result 

of the prior year reversal of $64 million in interest expense, previously recognized on a contingent regulatory 
liability, and increased interest expense due to higher regulatory liabilities and interest rates in the current year. 
Additionally, there was a $26 million increase at Mong Duong, mainly due to this entity no longer capitalizing 
interest as a result of the commencement of operations in April 2015. These increases were partially offset by lower 
interest expense of $22 million due to a reduction in debt principal at the Parent Company.

Interest expense decreased in 2015 from 2014 primarily due to lower interest expense of $63 million at the 

Parent Company due to a reduction in debt principal, and a $64 million reversal of interest expense previously 
recognized on a contingent regulatory liability at Eletropaulo. These decreases were partially offset by an increase 
at Mong Duong as the plant commenced operations in April 2015 and ceased capitalizing interest.

Interest income

Interest income increased in 2016 from 2015 primarily due to higher interest income of $19 million recognized 
on the financing element of the service concession arrangement at Mong Duong, which became fully operational in 
April 2015, partially offset by lower interest income of $16 million in Argentina due to prior year recognition of 
accumulated interest on VAT balances related to CAMESSA.

Interest income increased in 2015 from 2014 primarily due to interest income of $114 million recognized in 

2015 on the financing element of the service concession arrangement at Muong Duong, as well as an increase of 
$36 million at Eletropaulo resulting from higher interest rates and an increase in regulatory assets.

Loss on extinguishment of debt

Loss on extinguishment of debt was $13 million for the year ended December 31, 2016 primarily related to 

expense of $14 million recognized on debt extinguishment at the Parent Company.

Loss on extinguishment of debt was $182 million for the year ended December 31, 2015. This loss was 
primarily related to expense of $105 million, $22 million, and $19 million recognized on debt extinguishments at the 
Parent Company, IPL, and the Dominican Republic, respectively. 

Loss on extinguishment of debt was $261 million for the year ended December 31, 2014. This was primarily 
related to expense of $193 million, $31 million, and $20 million recognized on debt extinguishments at the Parent 

84

Company, DPL, and Gener, respectively.

Other income and expense

Other income decreased in 2016 from 2015 primarily due to gains on early contract termination in 2015 and 

lower gains on asset sales in 2016; partially offset by an increase in allowance for funds used during construction as 
a result of increased construction activity at IPL. 

Other income decreased in 2015 from 2014 primarily due to lower gains on asset sales in 2015 and the 2014 
reversal of a liability in Kazakhstan due to the expiration of a statute of limitations for the Republic of Kazakhstan to 
claim payment from AES. 

Other expense increased in 2016 from 2015 primarily due to the 2016 recognition a full allowance on a non-

trade receivable in the MCAC SBU as a result of payment delays and discussions with the counterparty. The 
allowance relates to certain reimbursements the Company was expecting in connection with a legal matter. 
Management believes the counterparty is obligated to pay and plans to continue to attempt to fully collect the non-
trade receivable.

Other expense decreased in 2015 from 2014 primarily due to lower losses on sales and disposal of assets at 

Termo Andes and Eletropaulo.

See Note 19—Other Income and Expense included in Item 8.—Financial Statements and Supplementary Data 

of this Form 10-K for further information.

Gain on disposal and sale of businesses

Gain on sale of businesses was $29 million for the year ended December 31, 2016, which was primarily 

related to the gain on sale of DPLER, partially offset by a loss on the deconsolidation of U.K. Wind.

Gain on sale of businesses was $29 million for the year ended December 31, 2015, which was primarily 

related to the sale of Armenia Mountain. 

Gain on disposal and sale of investments for the year ended December 31, 2014 was $358 million, which was 

primarily related to the sale of 45% of the Company's interest in Masinloc, as well as the sale of U.K. Wind 
(Operating Projects).

Goodwill impairment expense

There were no goodwill impairments for the year ended December 31, 2016.

Goodwill impairment expense was $317 million for the year ended December 31, 2015 due to a goodwill 

impairment at DP&L.

Goodwill impairment expense was $164 million for the year ended December 31, 2014. This expense 
consisted of $136 million, $20 million and $8 million of goodwill impairments at DPLER, Buffalo Gap II and Buffalo 
Gap I, respectively.

See Note 9—Goodwill and Other Intangible Assets included in Item 8.—Financial Statements and 

Supplementary Data of this Form 10-K for further information.

Asset impairment expense

Asset impairment expense was $1.1 billion for the year ended December 31, 2016. This was primarily related 

to asset impairments of $859 million, $159 million and $77 million at DPL, Buffalo Gap II and Buffalo Gap I, 
respectively.

Asset impairment expense was $285 million for the year ended December 31, 2015 primarily due to asset 
impairments of $121 million, $116 million and $37 million at Kilroot, Buffalo Gap III and U.K. Wind, respectively.

Asset impairment expense was $91 million for the year ended December 31, 2014 primarily due to asset 

impairments of $67 million, $12 million and $12 million at Ebute, U.K. Wind and DPL, respectively.

See Note 20—Asset Impairment Expense included in Item 8.—Financial Statements and Supplementary Data 

of this Form 10-K for further information.

Income tax expense 

Income tax decreased to a benefit of $188 million in 2016 as compared to expense of $472 million in 2015. 

The Company's effective tax rates were (137%) and 41% for the years ended December 31, 2016 and 2015, 
respectively.

85

The net decrease in the 2016 effective tax rate was due, in part, to the 2016 asset impairments in the U.S. and 

to the current year benefit related to a restructuring of one of our Brazilian businesses that increases tax basis in 
long-term assets. Further, the 2015 rate was impacted by the items described below. See Note 20—Asset 
Impairment Expense for additional information regarding the 2016 U.S. asset impairments.

Income tax expense increased $101 million, or 27%, to $472 million in 2015. The Company's effective tax 

rates were 41% and 26% for the years ended December 31, 2015 and 2014, respectively. 

The net increase in the 2015 effective tax rate was due, in part, to the nondeductible 2015 impairment of 
goodwill at our U.S. utility, DP&L and Chilean withholding taxes offset by the release of valuation allowance at 
certain of our businesses in Brazil, Vietnam and the U.S. Further, the 2014 rate was impacted by the sale of 
approximately 45% of the Company’s interest in Masin AES Pte Ltd., which owns the Company’s business interests 
in the Philippines and the 2014 sale of the Company’s interests in four U.K. wind operating projects. Neither of 
these transactions gave rise to income tax expense. See Note 15—Equity for additional information regarding the 
sale of approximately 45% of the Company’s interest in Masin-AES Pte Ltd. See Note 23—Dispositions for 
additional information regarding the sale of the Company’s interests in four U.K. wind operating projects.

Our effective tax rate reflects the tax effect of significant operations outside the U.S., which are generally taxed 

at rates lower than the U.S. statutory rate of 35%. A future proportionate change in the composition of income 
before income taxes from foreign and domestic tax jurisdictions could impact our periodic effective tax rate. The 
Company also benefits from reduced tax rates in certain countries as a result of satisfying specific commitments 
regarding employment and capital investment. See Note 21—Income Taxes for additional information regarding 
these reduced rates.

Includes gains of $17 million, $247 million and $172 million on foreign currency derivative contracts for the years ended December 31, 2016, 2015 and 2014, 
respectively.

The Company recognized a net foreign currency transaction loss of $15 million for the year ended 

December 31, 2016 primarily due to losses of $50 million at The AES Corporation mainly due to remeasurement 
losses on intercompany notes, and losses on swaps and options.

This loss was partially offset by gains of $37 million in Argentina, mainly due to the favorable impact of foreign 

currency derivatives related to government receivables.

The Company recognized a net foreign currency transaction gain of $107 million for the year ended 

December 31, 2015 primarily due to gains of:

•  $124 million in Argentina, due to the favorable impact from foreign currency derivatives related to government 
receivables, partially offset by losses from the devaluation of the Argentine Peso associated with U.S. Dollar 
denominated debt, and losses at Termoandes (a U.S. Dollar functional currency subsidiary) primarily associated 
with cash and accounts receivable balances in local currency,

•  $29 million in Colombia, mainly due to the depreciation of the Colombian Peso, positively impacting Chivor (a 

U.S. Dollar functional currency subsidiary) due to liabilities denominated in Colombian Pesos,

•  $11 million in the United Kingdom, mainly due to the depreciation of the Pound Sterling, resulting in gains at 

Ballylumford Holdings (a U.S. Dollar functional currency subsidiary) associated with intercompany notes payable 
denominated in Pound Sterling, and

86

These gains were partially offset by losses of:

•  $31 million at The AES Corporation primarily due to decreases in the valuation of intercompany notes receivable 
denominated in foreign currency, resulting from the weakening of the Euro and British Pound during the year, 
partially offset by gains related to foreign currency option purchases, and

•  $18 million in Chile primarily due to the devaluation of the Chilean Peso at Gener (a U.S. Dollar functional 

currency subsidiary) from working capital denominated in Chilean Pesos, partially offset by gains on foreign 
currency derivatives.

The Company recognized a net foreign currency transaction gains of $11 million for the year ended December 

31, 2014 primarily due to gains of:

•  $66 million in Argentina, due to the favorable impact from foreign currency derivatives related to government 
receivables, partially offset by losses from the devaluation of the Argentine Peso associated with U.S. Dollar 
denominated debt, and losses at Termoandes (a U.S. Dollar functional currency subsidiary) primarily associated 
with cash and accounts receivable balances in local currency, and the purchase of Argentine sovereign bonds,
•  $17 million in Colombia, mainly due to a 23% depreciation of the Colombian Peso, positively impacting Chivor (a 
U.S. Dollar functional currency subsidiary) due to liabilities denominated in Colombian Pesos, primarily income 
tax payable and accounts payable,

•  $12 million in the United Kingdom, mainly due to a 6% depreciation of the Pound Sterling, resulting in gains at 

Ballylumford Holdings (a U.S. Dollar functional currency subsidiary) associated with intercompany notes payable 
denominated in Pound Sterling, and gains related to foreign currency derivatives, and

•  $11 million in the Philippines, mainly due to amortization of frozen embedded derivatives and a 4% appreciation 
of the Philippine Peso against the U.S. Dollar, resulting in a revaluation of cash accounts, customer receivables, 
and deferred tax asset.

These gains were partially offset by losses of:

•  $34 million at The AES Corporation primarily due to decreases in the valuation of intercompany notes receivable 
denominated in foreign currency, resulting from the weakening of the Euro and British Pound during the year, 
partially offset by gains related to foreign currency option purchases,

•  $30 million in Chile primarily due to a 16% devaluation of the Chilean Peso, resulting in a $39 million loss at 
Gener (a U.S. Dollar functional currency subsidiary) from working capital denominated in Chilean Pesos, 
primarily cash, accounts receivable and VAT receivables, partially offset by income of $9 million on foreign 
currency derivatives, and

•  $14 million in Mexico, primarily due to a 13% devaluation of the Mexican Peso, resulting in a loss at TEGTEP 

and Merida (U.S. Dollar functional currency subsidiaries) from working capital denominated in Pesos (primarily 
cash, recoverable tax, and VAT).

Other non-operating expense

There were no significant non-operating expenses for the years ended December 31, 2016 and 2015.

Other non-operating expense was $128 million for the year ended December 31, 2014 due to impairments 

recognized at Entek and Silver Ridge. 

See Note 8—Other Non-Operating Expense included in Item 8.—Financial Statements and Supplementary 

Data of this Form 10-K for further information.

Net equity in earnings of affiliates

Net equity in earnings of affiliates decreased in 2016 compared to 2015 as a result of the restructuring of 
Guacolda in September 2015, which resulted in a $66 million benefit. No comparable transaction occurred in 2016.

Net equity in earnings of affiliates increased in 2015 compared to 2014 as a result of the restructuring of 

Guacolda in September 2015, which resulted in a $66 million benefit, as well as the impairment at Elsta in 2014. 

See Note 7—Investments In and Advances to Affiliates included in Item 8.—Financial Statements and 

Supplementary Data of this Form 10-K for further information.

87

Income from continuing operations attributable to noncontrolling interests

Income from continuing operations attributable to noncontrolling interests decreased in 2016 compared to 

2015 as a result of:

•  a decrease at Tietê due to lower earnings

•  a decrease at Eletropaulo resulting from the the reversal of a contingent regulatory liability in 2015, and
•  asset impairments at Buffalo Gap I and II; 

Partially offset by:

•  a lower asset impairment at Buffalo Gap III in 2015, and

• 

income tax benefits at Eletropaulo.

Income from continuing operations attributable to noncontrolling interests increased in 2015 compared to 2014 

as a result of:

•  an increase at Mong Duong due to commencement of operations in 2015,

•  an increase at Gener primarily due to the restructuring of Guacolda,
•  an increase at Masinloc due to increased earnings in 2015 and the 2014 sale of a noncontrolling interest in that 

business

Partially offset by:

•  a decrease at Buffalo Gap III resulting from the asset impairment expense allocation to the tax equity partner, 

and

•  a decrease at Eletropaulo resulting from unfavorable foreign exchange and lower demand. 

Loss from discontinued operations

Total loss from discontinued operations in 2016 and 2015 was due to the sale of AES Sul. The loss in 2016 

includes an after tax loss on impairment of $382 million recognized in the second quarter of 2016 and an additional 
after tax loss on sale of $737 million upon disposal of AES Sul in October 2016. There were no significant changes 
in loss from operations related to the AES Sul discontinued business. 

Total income from discontinued operations for the year ended December 31, 2014 was primarily due to AES 

Sul, Cameroon, Saurashtra and U.S. wind projects. 

See Note 22—Discontinued Operations included in Item 8.—Financial Statements and Supplementary Data of 

this Form 10-K for further information.

Net income (loss) attributable to The AES Corporation

Net income (loss) attributable to The AES Corporation decreased in 2016 compared to 2015 as a result of:

impairments and loss on sale at discontinued businesses;

• 
•  higher impairment expense on long lived assets; 

• 

• 

• 

• 

• 

lower operating margins at our US, Brazil and Europe SBUs;

lower equity in earnings of affiliates due to the 2015 restructuring at Guacolda; and

lower gains on foreign currency derivatives. 

These decreases were partially offset by:

lower effective tax rate;

lower debt extinguishment expense; and

•  absence of goodwill impairment expense.

Net income attributable to The AES Corporation decreased in 2015 compared to 2014 as result of:

•  Higher impairment expense

•  Lower gains from the sale of businesses

These decreases were partially offset by:

•  Lower debt extinguishment expense

SBU Performance Analysis

Non-GAAP Measures

Adjusted Operating Margin, Adjusted PTC, Adjusted EPS, and Proportional Free Cash Flow are non-GAAP 

supplemental measures that are used by management and external users of our consolidated financial statements 
such as investors, industry analysts and lenders. 

Adjusted Operating Margin 

We define Adjusted Operating Margin as Operating Margin, adjusted for the impact of NCI, excluding 

unrealized gains or losses related to derivative transactions. See Review of Consolidated Results of Operations for 
definitions of Operating Margin and cost of sales.

The GAAP measure most comparable to Adjusted Operating Margin is Operating Margin. We believe that 
Adjusted Operating Margin better reflects the underlying business performance of the Company. Factors in this 
determination include the impact of NCI, where AES consolidates the results of a subsidiary that is not wholly 
owned by the Company, as well as the variability due to unrealized derivatives gains or losses. Adjusted Operating 
Margin should not be construed as an alternative to Operating Margin, which is determined in accordance with 
GAAP.

Adjusted PTC 

We define Adjusted PTC as pretax income from continuing operations attributable to The AES Corporation 
excluding gains or losses due to (a) unrealized gains or losses related to derivative transactions, (b) unrealized 
foreign currency gains or losses, (c) gains or losses due to dispositions and acquisitions of business interests, 
(d) losses due to impairments, and (e) costs due to the early retirement of debt. Adjusted PTC also includes net 
equity in earnings of affiliates on an after-tax basis adjusted for the same gains or losses excluded from 
consolidated entities.

Adjusted PTC reflects the impact of NCI and excludes the items specified in the definition above. In addition to 

the revenue and cost of sales reflected in Operating Margin, Adjusted PTC includes the other components of our 
income statement, such as general and administrative expense in the corporate segment, as well as business 
development costs; interest expense and interest income; other expense and other income; realized foreign 
currency transaction gains and losses; and net equity in earnings of affiliates.

The GAAP measure most comparable to Adjusted PTC is income from continuing operations attributable to 

The AES Corporation. We believe that Adjusted PTC better reflects the underlying business performance of the 
Company and is considered in the Company's internal evaluation of financial performance. Factors in this 
determination include the variability due to unrealized gains or losses related to derivative transactions, unrealized 
foreign currency gains or losses, losses due to impairments and strategic decisions to dispose of or acquire 
business interests or retire debt, which affect results in a given period or periods. In addition, earnings before tax 
represents the business performance of the Company before the application of statutory income tax rates and tax 
adjustments, including the effects of tax planning, corresponding to the various jurisdictions in which the Company 
operates. Adjusted PTC should not be construed as an alternative to income from continuing operations attributable 
to The AES Corporation, which is determined in accordance with GAAP.

Adjusted EPS 

We define Adjusted EPS as diluted earnings per share from continuing operations excluding gains or losses of 

both consolidated entities and entities accounted for under the equity method due to (a) unrealized gains or losses 
related to derivative transactions, (b) unrealized foreign currency gains or losses, (c) gains or losses due to 
dispositions and acquisitions of business interests, (d) losses due to impairments, and (e) costs due to the early 
retirement of debt.

The GAAP measure most comparable to Adjusted EPS is diluted earnings per share from continuing 

operations. We believe that Adjusted EPS better reflects the underlying business performance of the Company and 
is considered in the Company's internal evaluation of financial performance. Factors in this determination include 
the variability due to unrealized gains or losses related to derivative transactions, unrealized foreign currency gains 
or losses, losses due to impairments and strategic decisions to dispose of or acquire business interests or retire 
debt, which affect results in a given period or periods. Adjusted EPS should not be construed as an alternative to 
diluted earnings per share from continuing operations, which is determined in accordance with GAAP.

Proportional Free Cash Flow 

We define proportional free cash flow as cash flows from operating activities less maintenance capital 
expenditures (including non-recoverable environmental capital expenditures), adjusted for the estimated impact of 
noncontrolling interests. The proportionate share of cash flows and related adjustments attributable to 
noncontrolling interests in our subsidiaries comprise the proportional adjustment factor presented in the 
reconciliation below. Upon the Company's adoption of the accounting guidance for service concession 
arrangements effective January 1, 2015, capital expenditures related to service concession assets that would have 
been classified as investing activities on the Consolidated Statement of Cash Flows are now classified as operating 
activities. See Note 1—General and Summary of Significant Accounting Policies of this Form 10-K for further 
information on the adoption of this guidance.

Beginning in the quarter ended March 31, 2015, the Company changed the definition of proportional free cash 
flow to exclude the cash flows for capital expenditures related to service concession assets that are now classified 
within net cash provided by operating activities on the Consolidated Statement of Cash Flows. The proportional 
adjustment factor for these capital expenditures is presented in the reconciliation below.

We also exclude environmental capital expenditures that are expected to be recovered through regulatory, 

contractual or other mechanisms. An example of recoverable environmental capital expenditures is IPL's 
investment in MATS-related environmental upgrades that are recovered through a tracker. See Item 1.—US SBU—
IPL—Environmental Matters for details of these investments.

The GAAP measure most comparable to proportional free cash flow is cash flows from operating activities. We 

believe that proportional free cash flow better reflects the underlying business performance of the Company, as it 
measures the cash generated by the business, after the funding of maintenance capital expenditures, that may be 
available for investing in growth opportunities or repaying debt. Factors in this determination include the impact of 
noncontrolling interests, where AES consolidates the results of a subsidiary that is not wholly-owned by the 
Company.

92

The presentation of free cash flow has material limitations. Proportional free cash flow should not be construed 

as an alternative to cash from operating activities, which is determined in accordance with GAAP. Proportional free 
cash flow does not represent our cash flow available for discretionary payments because it excludes certain 
payments that are required or to which we have committed, such as debt service requirements and dividend 
payments. Our definition of proportional free cash flow may not be comparable to similarly titled measures 
presented by other companies.

Beginning in the first quarter of 2017, we will no longer include these non-GAAP proportional free cash flow 

disclosures that have historically been provided and will instead disclose non-GAAP free cash flows only on a 
consolidated basis. Our use of proportional free cash flow was intended to provide investors with an understanding 
of the portion of free cash flows attributable to AES after the impact of non-controlling interests. However, since the 
concept of a non-controlling interest is not contemplated under GAAP with respect to the statement of cash flows, 
we will no longer be able to disclose proportional free cash flow in light of recent interpretive guidance issued by the 
SEC staff.

Service concession asset expenditures are excluded from the proportional free cash flow non-GAAP metric. 

The proportional adjustment factor, proportional maintenance capital expenditures (net of reinsurance proceeds) and proportional non-recoverable 
environmental capital expenditures are calculated by multiplying the percentage owned by noncontrolling interests for each entity by its corresponding 
consolidated cash flow metric and are totaled to the resulting figures. For example, Parent Company A owns 20% of Subsidiary Company B, a consolidated 
subsidiary. Thus, Subsidiary Company B has an 80% noncontrolling interest. Assuming a consolidated net cash flow from operating activities of $100 from 
Subsidiary B, the proportional adjustment factor for Subsidiary B would equal $80 (or $100 x 80%). The Company calculates the proportional adjustment 
factor for each consolidated business in this manner and then sums these amounts to determine the total proportional adjustment factor used in the 
reconciliation. The proportional adjustment factor may differ from the proportion of income attributable to noncontrolling interests as a result of (a) non-cash 
items which impact income but not cash and (b) AES' ownership interest in the subsidiary where such items occur. 

Includes proportional adjustment amount for service concession asset expenditures of $15 million and $84 million for the years ended December 31, 2016 
and 2015, respectively. The Company adopted service concession accounting effective January 1, 2015.

Excludes IPL's proportional recoverable environmental capital expenditures of $132 million, $205 million and $163 million for the years ended December 31, 
2016, 2015 and 2014, respectively.

Parent Free Cash Flow (a non-GAAP measure)

The Company defines Parent Free Cash Flow as dividends and other distributions received from our operating 

businesses less certain cash costs at the Parent Company level, primarily interest payments, overhead, and 
development costs. Parent Free Cash Flow is used to fund shareholder dividends, share repurchases, growth 
investments, recourse debt repayments, and other uses by the Parent Company. Refer to Item 1—Business—
Overview for further discussion of the Parent Company's capital allocation strategy.

Fiscal year 2016 versus 2015

Operating margin decreased $39 million, or 6%, which was driven primarily by the following:

US Generation

Southland related to an increase in depreciation expense as a result of a change in estimated useful lives of the plants
Impact from sale of Armenia Mountain in July 2015
Warrior Run due to lower availability and higher maintenance cost primarily due to major outages in 2016
Laurel Mountain due to lower regulation dispatch as well as lower energy and regulation pricing
Other

Total US Generation Decrease

DPL

Impact of lower wholesale prices and completion of DP&L’s transition to a competitive-bid market
Decrease in RTO capacity and other revenues primarily due to lower capacity cleared in the auction
Lower depreciation expense due to June 2016 fixed asset impairment and decrease in generating facility maintenance and
other expenses

Adjusted Operating Margin decreased $85 million for the US SBU due to the drivers above, excluding the 

impact of unrealized derivative gains and losses and adjusted for the impact of noncontrolling interests. 

Adjusted PTC decreased $13 million driven by the decrease of $85 million in Adjusted Operating Margin 
described above, partially offset by a gain on contract termination at DP&L, lower interest expense at DPL and IPL 
in part due to the sell-down impacts as discussed above and the impact of HLBV at our Distributed Energy business 
as a result of new projects achieving COD in 2016. 

Proportional Free Cash Flow increased $23 million, primarily driven by a $93 million decrease in coal 
purchases due to the ongoing conversion of coal generation assets to natural gas at IPL, a build-up of inventory 
due to mild winter weather in December 2015, and inventory optimization efforts at DPL. Additionally, Proportional 
Free Cash Flow benefited from a $32 million increase in accounts payable due to the timing of vendor payments, 
$17 million in net settlements of accounts receivable primarily resulting from the sale of DPLER in 2016, and lower 
interest payments of $19 million due to timing and lower interest rates. These positive impacts were partially offset 
by an $81 million decrease in Adjusted Operating Margin (net of non-cash impacts of $4 million, primarily related to 
the implementation of IPL’s new rates and depreciation), and a $84 million decrease in the timing of receivables 
collections resulting primarily from higher rates at IPL, more favorable weather in 2016, and the impact of DPLER’s 
declining customer base in 2015. 

Fiscal year 2015 versus 2014 

Operating margin decreased by $78 million, or 11%, which was driven primarily by the following:

DPL

Impact of more of DP&L's generation being sold in the wholesale market at lower prices in 2015 compared to supplying DP&L
retail customers in 2014, lower generation driven by plant outages in 2015, and unfavorable weather; partially offset by the
impact of outages and lower gas availability occurring in Q1 2014
Increase in capacity margin due to increase in PJM capacity price
Total DPL Decrease

US Generation

Lower production and prices across the US Wind businesses
Lower availability and dispatch at Hawaii

Total US Generation Decrease

IPL

Lower wholesale margin due to lower market prices of electricity and outages

Adjusted Operating Margin decreased $113 million at the US SBU due to the drivers above, excluding the 

95

impact of unrealized derivative gains and losses and adjusted for the impact of noncontrolling interests. 

Adjusted PTC decreased $85 million driven by the decrease of $113 million in Adjusted Operating Margin 

described above as well as a decrease in the Company's share of earnings under the HLBV allocation of 
noncontrolling interest at Buffalo Gap, partially offset by IPL due to lower interest expense related to the impact of 
the sell down and increased AFUDC, and DPL due to lower interest expense.

Proportional Free Cash Flow decreased $55 million, primarily driven by the $113 million decrease in Adjusted 

Operating Margin described above, and a $22 million increase in maintenance and non-recoverable capital 
expenditures. These negative impacts were partially offset by a $22 million increase due to the collection of 
previously deferred storm costs, a one-time payment of $19 million in 2014 to terminate an unfavorable coal 
contract, higher collections of $16 million due to settlement of a receivable balance related to the sale of MC2 in 
2015, and the timing of inventory payments of $16 million at DPL. Additionally, Proportional Free Cash Flow was 
favorably impacted by the timing of power purchase payments of $7 million and the timing of $9 million of 
receivables collections at IPL.

Fiscal year 2016 versus 2015 

Including the unfavorable impact of foreign currency translation and remeasurement of $36 million, operating 

margin increased $16 million, or 3%, which was driven primarily by the following:

Gener

Lower spot prices on energy and fuel purchases
Start of operations of Cochrane Plant
Other

Total Gener Increase

Adjusted Operating Margin decreased $24 million for the year due to the drivers above, adjusted for the impact 

of noncontrolling interests. 

Adjusted PTC decreased $92 million, driven by the decrease in Equity Earnings of $54 million mainly related 

to Guacolda’s reorganization in September 2015, the decrease of $24 million in Adjusted Operating Margin and the 
increase of $12 million in interest expense primarily associated to lower interest capitalization after beginning of 
commercial operations at Cochrane.

Proportional Free Cash Flow increased $40 million, primarily driven by $57 million in collections of financing 

receivables and the timing of maintenance remuneration from CAMMESSA in Argentina, a $25 million positive 
impact related to a one-time interest rate swap termination payment at Ventanas in July 2015, a decrease of $58 
million in working capital requirements at Chivor mainly related to collections of prior period sales, and a $23 million 
reduction in proportional maintenance and non-recoverable capital expenditures due to lower expenditures on 

96

emissions control equipment at Chile. These positive impacts were partially offset by a reduction of $4 million in 
Adjusted Operating Margin (net of non-cash impacts), $43 million of lower VAT refunds related to our Cochrane and 
Alto Maipo construction projects, higher net tax payments of $56 million primarily related to withholding taxes paid 
on Chilean distributions to AES Affiliates and higher taxable income in Colombia, and $18 million of higher interest 
payments primarily as a consequence of debt refinancing at higher interest rates and lower interest capitalization 
under construction projects.

Fiscal year 2015 versus 2014 

Including the unfavorable impact of foreign currency translation and remeasurement of $87 million, operating 

margin increased $31 million, or 5%, which was driven primarily by the following:

Gener

Higher margins associated to Nueva Renca Plant tolling agreement
Higher volume of energy sales mainly related to higher availability
Other

Adjusted Operating Margin increased $22 million for the year due to the drivers above, adjusted for the impact 

of noncontrolling interests. 

Adjusted PTC increased $61 million driven by a restructuring of Guacolda in Chile which increased our equity 

investment and resulted in additional Equity Earnings of $46 million as well as realized FX gains, lower interest 
expense at Chivor and the $22 million in Adjusted Operating Margin described above. This was partially offset by 
lower equity earnings at Guacolda of $16 million (excluding restructuring impact above) mainly driven by a 2014 
gain on sale of a transmission line.

Proportional Free Cash Flow increased $48 million, primarily driven by $107 million higher VAT refunds at 
Cochrane and Alto Maipo, $27 million of non-recurring maintenance collections in Argentina, and a $17 million 
decrease in interest payments. These positive impacts were partially offset by $49 million of higher tax payments 
and $25 million of lower collections primarily from contract customers at Chivor, and a $25 million impact related to 
a one-time interest rate swap termination payment at Ventanas in July 2015.

Adjusted PTC decreased $89 million, driven by the decrease of $79 million in Adjusted Operating Margin 
described above as well as higher interest expense of $10 million related to the reversal of a contingent regulatory 
liability at Eletropaulo in 2015.

Proportional Free Cash Flow increased by $139 million, primarily driven by favorable timing of $309 million in 

net collections of higher costs deferred in net regulatory assets in the prior year at Eletropaulo and Sul as a result of 
unfavorable hydrology in prior periods, favorable timing of $133 million in collections on current year energy sales, 
and lower energy purchases of $23 million at Tietê due to favorable hydrology. These positive impacts were partially 
offset by unfavorable timing of $241 million in payments for energy purchases and regulatory charges at 
Eletropaulo and Sul, and a $72 million decrease in in Adjusted Operating Margin (net of $7 million in non-cash 
impacts, primarily due to the reversal of a contingent regulatory liability at Eletropaulo in 2015).

Fiscal year 2015 versus 2014 

Including the unfavorable impact of foreign currency translation of $228 million, operating margin decreased

Adjusted Operating Margin classified as a discontinued operation (not included in the $1 million increase in 
Adjusted Operating Margin described above), higher energy purchases of $59 million at Tietê due to the timing of 
purchases in the spot market at higher prices, unfavorable timing of $32 million of higher costs deferred in net 
regulatory assets at Sul as result of unfavorable hydrology, and $17 million of higher interest payments at Sul due to 
a higher debt balance and higher interest rate. These negative impacts were partially offset by favorable timing of 
$121 million in payments for energy purchases and regulatory charges at Eletropaulo and Sul, $31 million of lower

Adjusted Operating Margin decreased $25 million due to the drivers above, adjusted for the impact of 

noncontrolling interests and excluding unrealized gains and losses on derivatives.

Adjusted PTC decreased $60 million, driven by the decrease in Adjusted Operating Margin of $25 million as 

described above as well as a 2015 compensation agreement regarding early termination of the original Barge PPA 
of $10 million and a $26 million allowance recognized in 2016 at Puerto Rico.

Proportional Free Cash Flow decreased $330 million, primarily driven by $212 million of lower collections in 

the Dominican Republic mainly due to collections of overdue receivables in September 2015, the $25 million 
decrease in Adjusted Operating Margin described above, $47 million of decreased collections in Puerto Rico due to 
lower sales, $14 million of higher tax payments in El Salvador due to higher taxable income in 2015, and a $10 
million impact from compensation received in the prior-year from the off-taker in Panama related to an early 
termination of the barge PPA.

Adjusted Operating Margin decreased $44 million due to the drivers above adjusted for the impact of 

noncontrolling interests and excluding unrealized gains and losses on derivatives. 

Adjusted PTC decreased $25 million, driven by the decrease in Adjusted Operating Margin of $44 million 
described above. These results were partially offset by a compensation agreement regarding early termination of 
the original Barge PPA of $10 million and 2014 losses on a legal dispute settlement of $4 million in Panama as well 
as lower interest expense due to lower debt at Puerto Rico.

Proportional Free Cash Flow increased $217 million, primarily due to the favorable timing of $220 million of 
collections, mainly related to the collection of overdue receivables in the Dominican Republic in September 2015. 
Proportional Free Cash Flow also benefited from a $17 million impact of lower energy purchases in El Salvador due 
to lower fuel prices, and a $10 million impact from compensation received from the off-taker in Panama related to 
an early termination of the barge PPA. These favorable impacts were partially offset by the $44 million decrease in 
Adjusted Operating Margin as described above.

Margin described above.

Proportional Free Cash Flow increased $314 million, primarily driven by $360 million of increased collections 

at Maritza from NEK, net of payments to the fuel supplier (MMI), and a decrease in maintenance and non-
recoverable environmental capital expenditures of $21 million. These favorable increases were partially offset by 
the $51 million decrease in Adjusted Operating Margin and a $24 million decrease in CO2 allowances due to a price 
decrease.

due to the reversal of a liability in 2014 in Kazakhstan. These results partially offset by lower interest expenses in 
Bulgaria.

Proportional Free Cash Flow increased $41 million, primarily driven by $69 million of increased collections at 

Maritza from NEK, net of payments to the fuel supplier (MMI), a $22 million benefit at IPP4 Jordan due to the

Adjusted Operating Margin increased $10 million due to the drivers above adjusted for the impact of 

noncontrolling interests.

Adjusted PTC was neutral driven by the increase of $10 million in Adjusted Operating Margin described above 

offset by lower equity earnings at OPGC in India due to lower tariffs and the net impact of higher interest expense 
and higher interest income at Mong Duong.

Proportional Free Cash Flow increased $49 million, primarily driven by a decrease of $29 million in working 
capital requirements at Mong Duong due to a build up in the prior year in preparation for commencement of plant 
operations, and an increase in Adjusted Operating Margin of $35 million (net of non-cash service concession 
expense of $24 million). These positive impacts were partially offset by higher interest expense of $18 million as 
interest is no longer capitalized as part of service concession asset expenditures.

Adjusted PTC increased $50 million, driven by the increase of $19 million in Adjusted Operating Margin 
described above, and the additional net impact of $28 million at Mong Duong due to a component of service 
concession revenue recognized as interest income, net of higher interest expense as interest is no longer 
capitalized. See Note 1—General and Summary of Significant Accounting Policies in Part II.—Item 8.—Financial 
Statements and Supplementary Data for further information regarding the accounting for service concession 
arrangements.

Proportional Free Cash Flow increased $5 million, primarily driven by an increase in Adjusted Operating 

Margin of $28 million (net of $9 million in non-cash items, primarily service concession expense and the 

102

retrospective adjustment to energy prices noted above), and $58 million in higher interest income recognized at 
Mong Duong as a result of the financing component under service concession accounting. These positive impacts 
were partially offset by $26 million in higher working capital requirements at Mong Duong due to a build-up in 
preparation of the commencement of operations, $22 million in higher interest payments at Mong Duong, $11 
million of higher tax payments at Masinloc, and $9 million in higher working capital requirements at Masinloc due 
primarily to the timing of coal purchases.

Key Trends and Uncertainties 

During 2017 and beyond, we expect to face the following challenges at certain of our businesses. 

Management expects that improved operating performance at certain businesses, growth from new businesses and 
global cost reduction initiatives may lessen or offset their impact. If these favorable effects do not occur, or if the 
challenges described below and elsewhere in this section impact us more significantly than we currently anticipate, 
or if volatile foreign currencies and commodities move more unfavorably, then these adverse factors (or other 
adverse factors unknown to us) may impact our operating margin, net income attributable to The AES Corporation 
and cash flows. We continue to monitor our operations and address challenges as they arise. For the risk factors 
related to our business, see Item 1.—Business and Item 1A.—Risk Factors of this Form 10-K. 

Macroeconomic and Political

During 2016, the political environments in some countries where our subsidiaries conduct business have 
changed which could result in significant impacts to tax laws, and environmental and energy policies. Additionally, 
we operate in multiple countries and as such are subject to volatility in exchange rates at the subsidiary level. See 
Item 7A.—Quantitative and Qualitative Disclosures About Market Risk for further information. 

Brazil — President Michel Temer, with majority congressional support, continues to implement the fiscal 
reforms needed to improve the country’s finances. While uncertainty dominates the political arena, if enacted, 
President Temer's market reforms would improve the the economic outlook, which may benefit our businesses in 
Brazil.

In October 2016, AES completed the sale of the Company's 100% ownership interest in AES Sul and 

recognized an after-tax loss on disposal of $737 million. This after-tax loss excludes the impact of contingent 
proceeds linked to the favorable settlement of pending litigation, which is not guaranteed. If the case is decided in 
the Company's favor, amounts would be remitted to AES over an unknown period of time. Any potential gain from 
the eventual resolution of this contingency would be presented separately as Discontinued Operations. 

United Kingdom — On June 23, 2016, the United Kingdom (U.K.) held a referendum in which voters approved 

an exit from the European Union (“E.U.”), commonly referred to as “Brexit”. As a result of the referendum, it is 
expected that the British government will begin negotiating the terms of the U.K.’s future relationship with the E.U. 
Although it is unclear what the long-term global implications will be, it is possible that the European or U.K. 
economy could weaken and our businesses may experience a decline in demand. While the full impact of the Brexit 
is uncertain, these changes may adversely affect our operations and financial results. The most immediate impact 
has been a devaluation of the pound and euro against the U.S. dollar. For 2016 and 2017, the Company has 
hedged against these foreign currency movements, however, the impact could be greater in future years. 

Puerto Rico — Our subsidiaries in Puerto Rico have long term PPAs with state-owned PREPA. Due to the 

ongoing economic situation in the territory, PREPA faces significant financial challenges. There have been no 
significant adverse impacts to AES Puerto Rico due to PREPA’s financial challenges. 

If PREPA continues to face challenges, or those challenges worsen, or otherwise impact PREPA’s ability to 

make payments to AES Puerto Rico, there could be a material impact on the Company. 

United States of America — The outcome of the 2016 U.S. elections could result in significant changes to U.S. 

tax laws, and environmental and energy policies, the impact of which is uncertain.

Philippines — The outcome of the 2016 Philippines election could result in changes in policies towards the 

U.S., China or other nations the impact of which on our business is uncertain.

Foreign Exchange and Commodities

Our businesses are exposed to and proactively manage market risk. Our primary market risk exposure is to 
the price of commodities, particularly electricity, oil, natural gas, coal and environmental credits. In 2016, there were 
more than 50% improvement in both oil and natural gas prices, which had a positive impact on our businesses in 
the Dominican Republic, Ohio and Northern Ireland. Since we operate in multiple countries, we are subject to 
volatility in exchange rates at varying degrees at the subsidiary level and between our functional currency, the U.S. 

103

Dollar, and currencies of the countries in which we operate. In 2016, we had a significant devaluation in the 
Argentine Peso. The Brazilian Real, Colombian Peso and Kazakhstani Tenge recovered during the year, but remain 
devalued as compared to the beginning of 2015, which had an offsetting impact on our 2016 results. For additional 
information, refer to Item 7A.—Quantitative and Qualitative Disclosures About Market Risk.

Alto Maipo

During 2016, the Alto Maipo project in Chile experienced technical difficulties in construction which resulted in 
an increase in projected costs of up to 22% over the original $2 billion budget. These additional costs have led to a 
series of negotiations with the main contractors, financiers and partners of the project, with the intention to 
restructure the existing financing and obtain additional financing to guarantee project completion. On January 19, 
2017, the parties agreed on the basis of the restructuring process, including new project milestones. These 
agreements are subject to the negotiation and finalization of the specific restructuring terms and conditions; and the 
negotiation and approval of the terms and conditions of each of the financing documents. Currently, the Company's 
indirect equity interest in the project is 40%.

Impairments 

Long-lived Assets — During the year ended December 31, 2016, the Company recognized asset impairment 

expense of $1.1 billion. Due to decreased wind production and a decline in forward power curves in 2016, the 
Company tested the recoverability of its long-lived assets at Buffalo Gap I, II, and III. After recognizing asset 
impairment expense of $236 million at Buffalo Gap I and II, the carrying value of the long-lived asset groups at 
Buffalo Gap I, II, and III totaled $242 million at December 31, 2016. 

Additionally, the Company recognized an asset impairment expense of $859 million at DPL in 2016. After 
recognizing asset impairment expense at DPL, the carrying value of the long-lived asset groups at DPL, including 
those that were not impaired, totaled $498 million at December 31, 2016. See Note 20—Asset Impairment Expense 
in Item 8.—Financial Statements and Supplementary Data for further information regarding the impairments at 
Buffalo Gap and DPL.

Events or changes in circumstances that may necessitate further recoverability tests and potential 

impairments of long-lived assets may include, but are not limited to, adverse changes in the regulatory environment, 
unfavorable changes in power prices or fuel costs, increased competition due to additional capacity in the grid, 
technological advancements, declining trends in demand, or an expectation that it is more likely than not that the 
asset will be disposed of before the end of its previously estimated useful life. 

Goodwill — The Company currently has no reporting units considered to be "at risk." A reporting unit is 

considered "at risk" when its fair value is not higher than its carrying amount by more than 10%. The Company 
monitors its reporting units at risk of Step 1 failure on an ongoing basis. It is possible that the Company may incur 
goodwill impairment charges at any reporting units containing goodwill in future periods if adverse changes in their 
business or operating environments occur. See Note 9—Goodwill and Other Intangible Assets in Item 8.—Financial 
Statements and Supplementary Data for further information. 

Capital Resources and Liquidity 

Overview — As of December 31, 2016, the Company had unrestricted cash and cash equivalents of $1.3 
billion, of which $100 million was held at the Parent Company and qualified holding companies. The Company also 
had $798 million in short term investments, held primarily at subsidiaries. In addition, we had restricted cash and 
debt service reserves of $871 million. The Company also had non-recourse and recourse aggregate principal 
amounts of debt outstanding of $15.8 billion and $4.7 billion, respectively. Of the approximately $1.3 billion of our 
current non-recourse debt, $1.2 billion was presented as such because it is due in the next twelve months and $128 
million relates to debt considered in default due to covenant violations. The defaults are not payment defaults, but 
are instead technical defaults triggered by failure to comply with other covenants and/or other conditions such as 
(but not limited to) failure to meet information covenants, complete construction or other milestones in an allocated 
time, meet certain minimum or maximum financial ratios, or other requirements contained in the non-recourse debt 
documents of the Company.

104

 We expect such current maturities will be repaid from net cash provided by operating activities of the 

subsidiary to which the debt relates or through opportunistic refinancing activity or some combination thereof. None 
of our recourse debt matures within the next twelve months. From time to time, we may elect to repurchase our 
outstanding debt through cash purchases, privately negotiated transactions or otherwise when management 
believes that such securities are attractively priced. Such repurchases, if any, will depend on prevailing market 
conditions, our liquidity requirements and other factors. The amounts involved in any such repurchases may be 
material. 

We rely mainly on long-term debt obligations to fund our construction activities. We have, to the extent 

available at acceptable terms, utilized non-recourse debt to fund a significant portion of the capital expenditures and 
investments required to construct and acquire our electric power plants, distribution companies and related assets. 
Our non-recourse financing is designed to limit cross default risk to the Parent Company or other subsidiaries and 
affiliates. Our non-recourse long-term debt is a combination of fixed and variable interest rate instruments. 
Generally, a portion or all of the variable rate debt is fixed through the use of interest rate swaps. In addition, the 
debt is typically denominated in the currency that matches the currency of the revenue expected to be generated 
from the benefiting project, thereby reducing currency risk. In certain cases, the currency is matched through the 
use of derivative instruments. The majority of our non-recourse debt is funded by international commercial banks, 
with debt capacity supplemented by multilaterals and local regional banks.

Given our long-term debt obligations, the Company is subject to interest rate risk on debt balances that accrue 
interest at variable rates. When possible, the Company will borrow funds at fixed interest rates or hedge its variable 
rate debt to fix its interest costs on such obligations. In addition, the Company has historically tried to maintain at 
least 70% of its consolidated long-term obligations at fixed interest rates, including fixing the interest rate through 
the use of interest rate swaps. These efforts apply to the notional amount of the swaps compared to the amount of 
related underlying debt. Presently, the Parent Company's only material un-hedged exposure to variable interest rate 
debt relates to indebtedness under its floating rate senior unsecured notes due 2019. On a consolidated basis, of 
the Company's $20.5 billion of total debt outstanding as of December 31, 2016, approximately $3.5 billion bore 
interest at variable rates that were not subject to a derivative instrument which fixed the interest rate. Brazil holds 
$1.3 billion of our floating rate non-recourse exposure as we have no ability to fix local debt interest rates efficiently.

In addition to utilizing non-recourse debt at a subsidiary level when available, the Parent Company provides a 

portion, or in certain instances all, of the remaining long-term financing or credit required to fund development, 
construction or acquisition of a particular project. These investments have generally taken the form of equity 
investments or intercompany loans, which are subordinated to the project's non-recourse loans. We generally 
obtain the funds for these investments from our cash flows from operations, proceeds from the sales of assets and/
or the proceeds from our issuances of debt, common stock and other securities. Similarly, in certain of our 
businesses, the Parent Company may provide financial guarantees or other credit support for the benefit of 
counterparties who have entered into contracts for the purchase or sale of electricity, equipment or other services 
with our subsidiaries or lenders. In such circumstances, if a business defaults on its payment or supply obligation, 
the Parent Company will be responsible for the business' obligations up to the amount provided for in the relevant 
guarantee or other credit support. At December 31, 2016, the Parent Company had provided outstanding financial 
and performance-related guarantees or other credit support commitments to or for the benefit of our businesses, 
which were limited by the terms of the agreements, of approximately $535 million in aggregate (excluding those 
collateralized by letters of credit and other obligations discussed below).

As a result of the Parent Company's below investment grade rating, counterparties may be unwilling to accept 

our general unsecured commitments to provide credit support. Accordingly, with respect to both new and existing 
commitments, the Parent Company may be required to provide some other form of assurance, such as a letter of 
credit, to backstop or replace our credit support. The Parent Company may not be able to provide adequate 
assurances to such counterparties. To the extent we are required and able to provide letters of credit or other 
collateral to such counterparties, this will reduce the amount of credit available to us to meet our other liquidity 
needs. At December 31, 2016, we had $6 million in letters of credit outstanding, provided under our senior secured 
credit facility, $245 million in letters of credit outstanding, provided under our un-senior secured credit facility and $3 
million in cash collateralized letters of credit outstanding outside of our senior secured credit facility. These letters of 
credit operate to guarantee performance relating to certain project development activities and business operations. 
During the year ended December 31, 2016, the Company paid letter of credit fees ranging from 0.2% to 2.5% per 
annum on the outstanding amounts.

We expect to continue to seek, where possible, non-recourse debt financing in connection with the assets or 

businesses that we or our affiliates may develop, construct or acquire. However, depending on local and global 
market conditions and the unique characteristics of individual businesses, non-recourse debt may not be available 

105

on economically attractive terms or at all. If we decide not to provide any additional funding or credit support to a 
subsidiary project that is under construction or has near-term debt payment obligations and that subsidiary is 
unable to obtain additional non-recourse debt, such subsidiary may become insolvent, and we may lose our 
investment in that subsidiary. Additionally, if any of our subsidiaries lose a significant customer, the subsidiary may 
need to withdraw from a project or restructure the non-recourse debt financing. If we or the subsidiary choose not to 
proceed with a project or are unable to successfully complete a restructuring of the non-recourse debt, we may lose 
our investment in that subsidiary.

Many of our subsidiaries depend on timely and continued access to capital markets to manage their liquidity 

needs. The inability to raise capital on favorable terms, to refinance existing indebtedness or to fund operations and 
other commitments during times of political or economic uncertainty may have material adverse effects on the 
financial condition and results of operations of those subsidiaries. In addition, changes in the timing of tariff 
increases or delays in the regulatory determinations under the relevant concessions could affect the cash flows and 
results of operations of our businesses.

Long-Term Receivables — As of December 31, 2016, the Company had approximately $264 million of 
accounts receivable classified as Noncurrent assets—other related to certain of its generation businesses in 
Argentina and the U.S. and its utility business in Brazil. The noncurrent portion primarily consists of accounts 
receivable in Argentina that, pursuant to amended agreements or government resolutions, have collection periods 
that extend beyond December 31, 2017, or one year from the latest balance sheet date. The majority of Argentinian 
receivables have been converted into long-term financing for the construction of power plants. See Note 6—
Financing Receivables included in Item 8.—Financial Statements and Supplementary Data and Item 1.—Business
—Regulatory Matters—Argentina of this Form 10-K for further information.

The following discussion of Parent Company Liquidity has been included because we believe it is a useful 
measure of the liquidity available to The AES Corporation, or the Parent Company, given the non-recourse nature of 
most of our indebtedness. Parent Company Liquidity as outlined below is a non-GAAP measure and should not be 
construed as an alternative to cash and cash equivalents which are determined in accordance with GAAP, as a 
measure of liquidity. Cash and cash equivalents are disclosed in the consolidated statements of cash flows. Parent 
Company Liquidity may differ from similarly titled measures used by other companies. The principal sources of 
liquidity at the Parent Company level are dividends and other distributions from our subsidiaries, including 
refinancing proceeds; proceeds from debt and equity financings at the Parent Company level, including availability 
under our credit facility; and proceeds from asset sales. Cash requirements at the Parent Company level are 
primarily to fund interest; principal repayments of debt; construction commitments; other equity commitments; 
common stock repurchases; acquisitions; taxes; Parent Company overhead and development costs; and dividends 
on common stock.

The Company defines Parent Company Liquidity as cash available to the Parent Company plus available 
borrowings under existing credit facility. The cash held at qualified holding companies represents cash sent to 
subsidiaries of the Company domiciled outside of the U.S.. Such subsidiaries have no contractual restrictions on 
their ability to send cash to the Parent Company. Parent Company Liquidity is reconciled to its most directly 
comparable U.S. GAAP financial measure, Cash and cash equivalents, at December 31, 2016 and 2015 as follows:

Parent Company Liquidity (in millions)

The Company paid dividends of $0.44 per share to its common stockholders during the year ended 

December 31, 2016. While we intend to continue payment of dividends and believe we will have sufficient liquidity 
to do so, we can provide no assurance that we will continue to pay dividends, or if continued, the amount of such 
dividends.

Recourse Debt — Our recourse debt at year-end was approximately $4.7 billion and $5.0 billion in 2016 and 

2015, respectively. See Note 11—Debt in Item 8.—Financial Statements and Supplementary Data of this Form 10-K 
for additional detail.

While we believe that our sources of liquidity will be adequate to meet our needs for the foreseeable future, 

this belief is based on a number of material assumptions, including, without limitation, assumptions about our ability 
to access the capital markets (see Key Trends and Uncertainties—Global Economic Conditions), the operating and 
financial performance of our subsidiaries, currency exchange rates, power market pool prices, and the ability of our 
subsidiaries to pay dividends. In addition, our subsidiaries' ability to declare and pay cash dividends to us (at the 
Parent Company level) is subject to certain limitations contained in loans, governmental provisions and other 
agreements. We can provide no assurance that these sources will be available when needed or that the actual cash 
requirements will not be greater than anticipated. See Item 1A.—Risk Factors—The AES Corporation is a holding 
company and its ability to make payments on its outstanding indebtedness, including its public debt securities, is 
dependent upon the receipt of funds from its subsidiaries by way of dividends, fees, interest, loans or otherwise, of 
this Form 10-K.

Various debt instruments at the Parent Company level, including our senior secured credit facility, contain 
certain restrictive covenants. The covenants provide for — among other items — limitations on other indebtedness, 
liens, investments and guarantees; limitations on dividends, stock repurchases and other equity transactions; 
restrictions and limitations on mergers and acquisitions, sales of assets, leases, transactions with affiliates and off-
balance sheet and derivative arrangements; maintenance of certain financial ratios; and financial and other 
reporting requirements.

As of December 31, 2016, we were in compliance with these covenants at the Parent Company level.

Non-Recourse Debt — While the lenders under our non-recourse debt financings generally do not have direct 

recourse to the Parent Company, defaults thereunder can still have important consequences for our results of 
operations and liquidity, including, without limitation:

• 

• 

• 

• 

reducing our cash flows as the subsidiary will typically be prohibited from distributing cash to the Parent 
Company during the time period of any default;
triggering our obligation to make payments under any financial guarantee, letter of credit or other credit 
support we have provided to or on behalf of such subsidiary;

causing us to record a loss in the event the lender forecloses on the assets; and

triggering defaults in our outstanding debt at the Parent Company.

For example, our senior secured credit facility and outstanding debt securities at the Parent Company include 

events of default for certain bankruptcy related events involving material subsidiaries. In addition, our revolving 
credit agreement at the Parent Company includes events of default related to payment defaults and accelerations of 
outstanding debt of material subsidiaries.

Some of our subsidiaries are currently in default with respect to all or a portion of their outstanding 

indebtedness. The total non-recourse debt classified as current in the accompanying Consolidated Balance Sheets 
amounts to $1.3 billion. The portion of current debt related to such defaults was $128 million at December 31, 2016, 
all of which was non-recourse debt related to two subsidiaries — Kavarna, and Sogrinsk. See Note 11—Debt in 
Item 8.—Financial Statements and Supplementary Data of this Form 10-K for additional detail.

None of the subsidiaries that are currently in default are subsidiaries that met the applicable definition of 
materiality under AES' corporate debt agreements as of December 31, 2016 in order for such defaults to trigger an 
event of default or permit acceleration under AES' indebtedness. However, as a result of additional dispositions of 

116

assets, other significant reductions in asset carrying values or other matters in the future that may impact our 
financial position and results of operations or the financial position of the individual subsidiary, it is possible that one 
or more of these subsidiaries could fall within the definition of a "material subsidiary" and thereby upon an 
acceleration trigger an event of default and possible acceleration of the indebtedness under the Parent Company's 
outstanding debt securities. A material subsidiary is defined in the Company's senior secured revolving credit facility 
as any business that contributed 20% or more of the Parent Company's total cash distributions from businesses for 
the four most recently completed fiscal quarters. As of December 31, 2016, none of the defaults listed above 
individually or in the aggregate results in or is at risk of triggering a cross-default under the recourse debt of the 
Company.

Includes recourse and non-recourse debt presented on the Consolidated Balance Sheet. These amounts exclude capital lease obligations which are included 
in the capital lease category.
Interest payments are estimated based on final maturity dates of debt securities outstanding at December 31, 2016 and do not reflect anticipated future 
refinancing, early redemptions or new debt issuances. Variable rate interest obligations are estimated based on rates as of December 31, 2016.
These amounts do not include current liabilities on the Consolidated Balance Sheet except for the current portion of uncertain tax obligations. Noncurrent 
uncertain tax obligations are reflected in the "Other" column of the table above as the Company is not able to reasonably estimate the timing of the future 
payments. In addition, these amounts do not include: (1) regulatory liabilities (See Note 10—Regulatory Assets and Liabilities), (2) contingencies (See 
Note 13—Contingencies), (3) pension and other post retirement employee benefit liabilities (see Note 14—Benefit Plans), (4) derivatives and incentive 
compensation (See Note 5—Derivative Instruments and Hedging Activities) or (5) any taxes (See Note 21—Income Taxes) except for uncertain tax 
obligations, as the Company is not able to reasonably estimate the timing of future payments. See the indicated notes to the Consolidated Financial 
Statements included in Item 8 of this Form 10-K for additional information on the items excluded.

As of December 31, 2016, the Company had no commitments to invest in subsidiaries under construction and 

to purchase related equipment that were not included in the letters of credit disclosed above.

We have a diverse portfolio of performance-related contingent contractual obligations. These obligations are 

designed to cover potential risks and only require payment if certain targets are not met or certain contingencies 
occur. The risks associated with these obligations include change of control, construction cost overruns, subsidiary 
default, political risk, tax indemnities, spot market power prices, sponsor support and liquidated damages under 
power sales agreements for projects in development, in operation and under construction. In addition, we have an 
asset sale program through which we may have customary indemnity obligations under certain assets sale 
agreements. While we do not expect that we will be required to fund any material amounts under these contingent 
contractual obligations beyond 2016, many of the events which would give rise to such obligations are beyond our 
control. We can provide no assurance that we will be able to fund our obligations under these contingent 
contractual obligations if we are required to make substantial payments thereunder.

Critical Accounting Policies and Estimates

 The Consolidated Financial Statements of AES are prepared in conformity with U.S. GAAP, which requires the 
use of estimates, judgments and assumptions that affect the reported amounts of assets and liabilities at the date of 
the financial statements and the reported amounts of revenue and expenses during the periods presented. AES' 
significant accounting policies are described in Note 1—General and Summary of Significant Accounting Policies to 
the Consolidated Financial Statements included in Item 8 of this Form 10-K.

An accounting estimate is considered critical if the estimate requires management to make assumptions about 

matters that were highly uncertain at the time the estimate was made; different estimates reasonably could have 
been used; or the impact of the estimates and assumptions on financial condition or operating performance is 
material.

Management believes that the accounting estimates employed are appropriate and the resulting balances are 

reasonable; however, actual results could materially differ from the original estimates, requiring adjustments to 
these balances in future periods. Management has discussed these critical accounting policies with the Audit 
Committee, as appropriate. Listed below are the Company's most significant critical accounting estimates and 
assumptions used in the preparation of the Consolidated Financial Statements.

Income Taxes — We are subject to income taxes in both the U.S. and numerous foreign jurisdictions. Our 
worldwide income tax provision requires significant judgment and is based on calculations and assumptions that are 
subject to examination by the Internal Revenue Service and other taxing authorities. The Company and certain of 
its subsidiaries are under examination by relevant taxing authorities for various tax years. The Company regularly 
assesses the potential outcome of these examinations in each tax jurisdiction when determining the adequacy of 
the provision for income taxes. Accounting guidance for uncertainty in income taxes prescribes a more likely than 
not recognition threshold. Tax reserves have been established, which the Company believes to be adequate in 
relation to the potential for additional assessments. Once established, reserves are adjusted only when there is 
more information available or when an event occurs necessitating a change to the reserves. While the Company 
believes that the amounts of the tax estimates are reasonable, it is possible that the ultimate outcome of current or 
future examinations may be materially different than the reserve amounts.

Because we have a wide range of statutory tax rates in the multiple jurisdictions in which we operate, any 

changes in our geographical earnings mix could materially impact our effective tax rate. Furthermore, our tax 
position could be adversely impacted by changes in tax laws, tax treaties or tax regulations or the interpretation or 
enforcement thereof and such changes may be more likely or become more likely in view of recent economic trends 
in certain of the jurisdictions in which we operate. As an example, new tax laws were enacted in February 2016 in 
Chile which increased the statutory income tax rate for most of our Chilean businesses from 25% to 25.5% in 2017 
and to 27% for 2018 and future years. Accordingly, in 2016 our net Chilean deferred tax liabilities were remeasured 
to the new rates. The remeasurement amount and other potential future impacts of the changes in tax law may be 
material to continuing operations. See Note 21—Income Taxes to the Consolidated Financial Statements included 
in Item 8 of this Form 10-K for additional information.

The Company's provision for income taxes could be adversely impacted by changes to the U.S. taxation of 

earnings of our foreign subsidiaries. Since 2006, the Company has benefited from the Controlled Foreign 
Corporation look-through rule, originally enacted in the TIPRA of 2005, subject to five temporary extensions, 
including the most recent five year retroactive extension enacted on December 18, 2015 in the H.R.2029 - 
Consolidated Appropriations Act, 2016. There can be no assurance that this provision will continue to be extended 
beyond December 31, 2019. Further, the U.S. is considering corporate tax reform that may significantly change 
corporate tax rates, business rules such as interest deductibility and capital expenditure cost recovery, and U.S. 
international tax rules. Our expected effective tax rate could increase by amounts that may be material to the 
Company should such reforms be enacted.

In addition, U.S. income taxes and foreign withholding taxes have not been provided on undistributed earnings 

for certain of our non-U.S. subsidiaries to the extent such earnings are considered to be indefinitely reinvested in 
the operations of those subsidiaries.

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences 

between the financial statement carrying amounts of the existing assets and liabilities, and their respective income 
tax bases. The Company establishes a valuation allowance when it is more likely than not that all or a portion of a 
deferred tax asset will not be realized.

Sales of Noncontrolling Interests — The accounting for a sale of noncontrolling interests under the 

accounting standards depends on whether the sale is considered to be a sale of in-substance real estate (as 

118

opposed to an equity transaction), where the gain (loss) on sale would be recognized in earnings rather than within 
stockholders' equity. If management's estimation process determines that there is no significant value beyond the 
in-substance real estate, the gain (loss) on the sale of the noncontrolling interest is recognized in earnings. 
However, if it is determined that significant value likely exists beyond the in-substance real estate, the gain (loss) on 
the sale of the noncontrolling interest would be recognized within stockholders' equity. In-substance real estate is 
comprised of land plus improvements and integral equipment. The determination of whether property, plant and 
equipment is integral equipment is based on the significance of the costs to remove the equipment from its existing 
location (including the cost of repairing damage resulting from the removal), combined with the decrease in the fair 
value of the equipment as a result of those removal activities. When the combined total of removal costs and the 
decrease in fair value of the equipment exceeds 10% of the fair value of the equipment, the equipment is 
considered integral equipment. The accounting standards specifically identify power plants as an example of in-
substance real estate. Where the consolidated entity in which noncontrolling interests have been sold contains in-
substance real estate, management estimates the extent to which the total fair value of the assets of the entity is 
represented by the in-substance real estate and whether significant value exists beyond the in-substance real 
estate. This estimation considers all qualitative and quantitative factors relevant for each sale and, where 
appropriate, includes making quantitative estimates about the fair value of the entity and its identifiable assets and 
liabilities (including any favorable or unfavorable contracts) by analogy to the accounting standards on business 
combinations. As such, these estimates may require significant judgment and assumptions, similar to the critical 
accounting estimates discussed below for impairments and fair value. 

Impairments — Our accounting policies on goodwill and long-lived assets are described in detail in Note 1—

General and Summary of Significant Accounting Policies, included in Item 8 of this Form 10-K. The Company 
makes considerable judgments in its impairment evaluations of goodwill and long-lived assets; however, the fair 
value determination is typically the most judgmental part in an impairment evaluation.

The Company determines the fair value of a reporting unit or a long-lived asset (asset group) by applying the 
approaches prescribed under the fair value measurement accounting framework. Generally, the market approach 
and income approach are most relevant in the fair value measurement of our reporting units and long-lived assets; 
however, due to the lack of available relevant observable market information in many circumstances, the Company 
often relies on the income approach. The Company may engage an independent valuation firm to assist 
management with the valuation. The decision to engage an independent valuation firm considers all relevant facts 
and circumstances, including a cost-benefit analysis and the Company's internal valuation knowledge of the long-
lived asset (asset group) or business. The Company develops the underlying assumptions consistent with its 
internal budgets and forecasts for such valuations. Additionally, the Company uses an internal discounted cash flow 
valuation model (the "DCF model"), based on the principles of present value techniques, to estimate the fair value 
of its reporting units or long-lived assets under the income approach. The DCF model estimates fair value by 
discounting our internal budgets and cash flow forecasts, adjusted to reflect market participant assumptions, to the 
extent necessary, at an appropriate discount rate.

Management applies considerable judgment in selecting several input assumptions during the development of 
our internal budgets and cash flow forecasts. Examples of the input assumptions that our budgets and forecasts are 
sensitive to include macroeconomic factors such as growth rates, industry demand, inflation, exchange rates, power 
prices and commodity prices. Whenever appropriate, management obtains these input assumptions from 
observable market data sources (e.g., Economic Intelligence Unit) and extrapolates the market information if an 
input assumption is not observable for the entire forecast period. Many of these input assumptions are dependent 
on other economic assumptions, which are often derived from statistical economic models with inherent limitations 
such as estimation differences. Further, several input assumptions are based on historical trends which often do not 
recur. The input assumptions most significant to our budgets and cash flows are based on expectations of 
macroeconomic factors which have been volatile recently. It is not uncommon that different market data sources 
have different views of the macroeconomic factor expectations and related assumptions. As a result, 
macroeconomic factors and related assumptions are often available in a narrow range; however, in some situations 
these ranges become wide and the use of a different set of input assumptions could produce significantly different 
budgets and cash flow forecasts.

A considerable amount of judgment is also applied in the estimation of the discount rate used in the DCF 
model. To the extent practical, inputs to the discount rate are obtained from market data sources (e.g., Bloomberg, 
Capital IQ, etc.). The Company selects and uses a set of publicly traded companies from the relevant industry to 
estimate the discount rate inputs. Management applies judgment in the selection of such companies based on its 
view of the most likely market participants. It is reasonably possible that the selection of a different set of likely 
market participants could produce different input assumptions and result in the use of a different discount rate.

119

Fair value of a reporting unit or a long-lived asset (asset group) is sensitive to both input assumptions to our 
budgets and cash flow forecasts and the discount rate. Further, estimates of long-term growth and terminal value 
are often critical to the fair value determination. As part of the impairment evaluation process, management 
analyzes the sensitivity of fair value to various underlying assumptions. The level of scrutiny increases as the gap 
between fair value and carrying amount decreases. Changes in any of these assumptions could result in 
management reaching a different conclusion regarding the potential impairment, which could be material. Our 
impairment evaluations inherently involve uncertainties from uncontrollable events that could positively or negatively 
impact the anticipated future economic and operating conditions.

Further discussion of the impairment charges recognized by the Company can be found within Note 9—

Goodwill and Other Intangible Assets, Note 20—Asset Impairment Expense and Note 8—Other Non-Operating 
Expense to the Consolidated Financial Statements included in Item 8 of this Form 10-K.

Fair Value

Fair Value Hierarchy — The Company uses valuation techniques and methodologies that maximize the use 

of observable inputs and minimize the use of unobservable inputs. Where available, fair value is based on 
observable market prices or parameters or derived from such prices or parameters. Where observable prices are 
not available, valuation models are applied to estimate the fair value using the available observable inputs. The 
valuation techniques involve some level of management estimation and judgment, the degree of which is 
dependent on the price transparency for the instruments or market and the instruments' complexity.

To increase consistency and enhance disclosure of the fair value of financial instruments, the fair value 
measurement standard includes a fair value hierarchy to prioritize the inputs used to measure fair value into three 
categories. An asset or liability's level within the fair value hierarchy is based on the lowest level of input significant 
to the fair value measurement, where Level 1 is the highest and Level 3 is the lowest. For more information 
regarding the fair value hierarchy, see Note 1—General and Summary of Significant Accounting Policies included in 
Item 8 of this Form 10-K.

Fair Value of Financial Instruments — A significant number of the Company's financial instruments are 
carried at fair value with changes in fair value recognized in earnings or other comprehensive income each period. 
The Company makes estimates regarding the valuation of assets and liabilities measured at fair value in preparing 
the Consolidated Financial Statements. These assets and liabilities include short and long-term investments in debt 
and equity securities, included in the balance sheet line items Short-term investments and Other assets 
(Noncurrent), derivative assets, included in Other current assets and Other assets (Noncurrent) and derivative 
liabilities, included in Accrued and other liabilities (current) and Other long-term liabilities. Investments are generally 
fair valued based on quoted market prices or other observable market data such as interest rate indices. The 
Company's investments are primarily certificates of deposit, government debt securities and money market funds. 
Derivatives are valued using observable data as inputs into internal valuation models. The Company's derivatives 
primarily consist of interest rate swaps, foreign currency instruments, and commodity and embedded derivatives. 
Additional discussion regarding the nature of these financial instruments and valuation techniques can be found in 
Note 4—Fair Value included in Item 8 of this Form 10-K.

Fair Value of Nonfinancial Assets and Liabilities — Significant estimates are made in determining the fair 

value of long-lived tangible and intangible assets (i.e., property, plant and equipment, intangible assets and 
goodwill) during the impairment evaluation process. In addition, the majority of assets acquired and liabilities 
assumed in a business combination are required to be recognized at fair value under the relevant accounting 
guidance. In determining the fair value of these items, management makes several assumptions as discussed in 
the Impairments section above.

Accounting for Derivative Instruments and Hedging Activities — We enter into various derivative 
transactions in order to hedge our exposure to certain market risks. We primarily use derivative instruments to 
manage our interest rate, commodity and foreign currency exposures. We do not enter into derivative transactions 
for trading purposes.

In accordance with the accounting standards for derivatives and hedging, we recognize all derivatives as 
either assets or liabilities in the balance sheet and measure those instruments at fair value except where derivatives 
qualify and are designated as "normal purchase/normal sale" transactions. Changes in fair value of derivatives are 
recognized in earnings unless specific hedge criteria are met. Income and expense related to derivative instruments 
are recognized in the same category as that generated by the underlying asset or liability. See Note 5—Derivative 
Instruments and Hedging Activities included in Item 8 of this Form 10-K for further information on the classification.

120

The accounting standards for derivatives and hedging enable companies to designate qualifying derivatives 

as hedging instruments based on the exposure being hedged. These hedge designations include fair value hedges 
and cash flow hedges. Changes in the fair value of a derivative that is highly effective and is designated and 
qualifies as a fair value hedge, are recognized in earnings as offsets to the changes in fair value of the exposure 
being hedged. The Company has no fair value hedges at this time. Changes in the fair value of a derivative that is 
highly effective and is designated as and qualifies as a cash flow hedge, are deferred in accumulated other 
comprehensive income and are recognized into earnings as the hedged transactions occur. Any ineffectiveness is 
recognized in earnings immediately. For all hedge contracts, the Company provides formal documentation of the 
hedge and effectiveness testing in accordance with the accounting standards for derivatives and hedging.

The fair value measurement accounting standard provides additional guidance on the definition of fair value 
and defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly 
transaction between market participants at the measurement date, or exit price. The fair value measurement 
standard requires the Company to consider and reflect the assumptions of market participants in the fair value 
calculation. These factors include nonperformance risk (the risk that the obligation will not be fulfilled) and credit 
risk, both of the reporting entity (for liabilities) and of the counterparty (for assets). Due to the nature of the 
Company's interest rate swaps, which are typically associated with non-recourse debt, credit risk for AES is 
evaluated at the subsidiary level rather than at the Parent Company level. Nonperformance risk on the Company's 
derivative instruments is an adjustment to the initial asset/liability fair value position that is derived from internally 
developed valuation models that utilize observable market inputs.

As a result of uncertainty, complexity and judgment, accounting estimates related to derivative accounting 

could result in material changes to our financial statements under different conditions or utilizing different 
assumptions. As a part of accounting for these derivatives, we make estimates concerning nonperformance, 
volatilities, market liquidity, future commodity prices, interest rates, credit ratings (both ours and our counterparty's), 
and future exchange rates. Refer to Note 4—Fair Value included in Item 8 of this Form 10-K for additional details.

The fair value of our derivative portfolio is generally determined using internal and third party valuation 
models, most of which are based on observable market inputs including interest rate curves and forward and spot 
prices for currencies and commodities. The Company derives most of its financial instrument market assumptions 
from market efficient data sources (e.g., Bloomberg, Reuters and Platt's). In some cases, where market data is not 
readily available, management uses comparable market sources and empirical evidence to derive market 
assumptions to determine a financial instrument's fair value. In certain instances, the published curve may not 
extend through the remaining term of the contract and management must make assumptions to extrapolate the 
curve. Specifically, where there is limited forward curve data with respect to foreign exchange contracts, beyond the 
traded points the Company utilizes the purchasing power parity approach to construct the remaining portion of the 
forward curve using relative inflation rates. Additionally, in the absence of quoted prices, we may rely on "indicative 
pricing" quotes from financial institutions to input into our valuation model for certain of our foreign currency swaps. 
These indicative pricing quotes do not constitute either a bid or ask price and therefore are not considered 
observable market data. For individual contracts, the use of different valuation models or assumptions could have a 
material effect on the calculated fair value.

Regulatory Assets — Management continually assesses whether the regulatory assets are probable of future 

recovery by considering factors such as applicable regulatory changes, recent rate orders applicable to other 
regulated entities and the status of any pending or potential deregulation legislation. If future recovery of costs 
ceases to be probable, any asset write-offs would be required to be recognized in operating income.

Consolidation — The Company has recently entered into several transactions whereby the Company sells an 

interest in its controlled subsidiaries and/or equity method investments. In connection with each transaction, the 
Company must determine whether the sale of the interest impacts the Company's consolidation conclusion by first 
determining whether the transaction should be evaluated under the variable interest model or the voting model. In 
determining which consolidation model applies to the transaction, the Company is required to make judgments 
about how the entity operates, the most significant of which are whether (i) the entity has sufficient equity to finance 
its activities, (ii) the equity holders, as a group, have the characteristics of a controlling financial interest, and (iii) 
whether the entity has non-substantive voting rights.

If the entity is determined to be a variable interest entity, the most significant judgment in determining whether 
the Company must consolidate the entity is whether the Company, including its related parties and de facto agents, 
collectively have power and benefits. If AES is determined to have power and benefits, the entity will be 
consolidated by AES.

121

Alternatively, if the entity is determined to be a voting model entity, the most significant judgments involve 

determining whether the non-AES shareholders have substantive participating rights. The assessment of 
shareholder rights and whether they are substantive participating rights requires significant judgment since the 
rights provided under shareholders' agreements may include selecting, terminating, and setting the compensation 
of management responsible for implementing the subsidiary's policies and procedures, establishing operating and 
capital decisions of the entity, including budgets, in the ordinary course of business. On the other hand, if 
shareholder rights are only protective in nature (referred to as protective rights) then such rights would not 
overcome the presumption that the owner of a majority voting interest shall consolidate its investee. Significant 
judgment is required to determine whether minority rights represent substantive participating rights or protective 
rights that do not affect the evaluation of control. While both represent an approval or veto right, a distinguishing 
factor is the underlying activity or action to which the right relates.

Pension and Other Postretirement Plans — Effective January 1, 2016 the Company applied a 

disaggregated discount rate approach for determining service cost and interest cost for its defined benefit pension 
plans and post-retirement plans in the U.S. and U.K. Refer to Note 1—General and Summary of Significant 
Accounting Policies included in Item 8 of this Form 10-K for further information.

New Accounting Pronouncements — See Note 1—General and Summary of Significant Accounting Policies 
included in Item 8 of this Form 10-K for further information about new accounting pronouncements adopted during 
2016 and accounting pronouncements issued but not yet effective.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 

Overview Regarding Market Risks — Our businesses are exposed to and proactively manage market risk. 

Our primary market risk exposure is to the price of commodities, particularly electricity, oil, natural gas, coal and 
environmental credits. In addition, our businesses are also exposed to lower electricity prices due to increased 
competition, including from renewable sources such as wind and solar, as a result of lower costs of entry and lower 
variable costs. We operate in multiple countries and as such are subject to volatility in exchange rates at varying 
degrees at the subsidiary level and between our functional currency, the U.S. Dollar, and currencies of the countries 
in which we operate. We are also exposed to interest rate fluctuations due to our issuance of debt and related 
financial instruments.

The disclosures presented in this Item 7A are based upon a number of assumptions; actual effects may differ. 
The safe harbor provided in Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange 
Act of 1934 shall apply to the disclosures contained in this Item 7A. For further information regarding market risk, 
see Item 1A.—Risk Factors, Our financial position and results of operations may fluctuate significantly due to 
fluctuations in currency exchange rates experienced at our foreign operations, Our businesses may incur 
substantial costs and liabilities and be exposed to price volatility as a result of risks associated with the electricity 
markets, which could have a material adverse effect on our financial performance, and We may not be adequately 
hedged against our exposure to changes in commodity prices or interest rates of this 2016 Form 10-K.

Commodity Price Risk — Although we prefer to hedge our exposure to the impact of market fluctuations in 
the price of electricity, fuels and environmental credits, some of our generation businesses operate under short-term 
sales or under contract sales that leave an unhedged exposure on some of our capacity or through imperfect fuel 
pass-throughs. In our utility businesses, we may be exposed to commodity price movements depending on our 
excess or shortfall of generation relative to load obligations and sharing or pass-through mechanisms. These 
businesses subject our operational results to the volatility of prices for electricity, fuels and environmental credits in 
competitive markets. We employ risk management strategies to hedge our financial performance against the effects 
of fluctuations in energy commodity prices. The implementation of these strategies can involve the use of physical 
and financial commodity contracts, futures, swaps and options. At our generation businesses for 2017-2019, 75% to 
80% of our variable margin is hedged against changes in commodity prices. At our utility businesses for 2017-2019, 
85% to 90% of our variable margin is insulated from changes in commodity prices. 

The portion of our sales and purchases that are not subject to such agreements or contracted businesses 

where indexation is not perfectly matched to business drivers will be exposed to commodity price risk. When 
hedging the output of our generation assets, we utilize contract sales that lock in the spread per MWh between 
variable costs and the price at which the electricity can be sold. 

AES businesses will see changes in variable margin performance as global commodity prices shift. For 2017, 

we project pretax earnings exposure on a 10% move in commodity prices would be approximately $15 million for 
U.S. power (DPL), $5 million for natural gas, $5 million for oil and $10 million for coal. Our estimates exclude 
correlation of oil with coal or natural gas. For example, a decline in oil or natural gas prices can be accompanied by 

122

a decline in coal price if commodity prices are correlated. In aggregate, the Company's downside exposure occurs 
with lower oil, lower natural gas, and higher coal prices. Exposures at individual businesses will change as new 
contracts or financial hedges are executed, and our sensitivity to changes in commodity prices generally increases 
in later years with reduced hedge levels at some of our businesses.

Commodity prices affect our businesses differently depending on the local market characteristics and risk 

management strategies. Spot power prices, contract indexation provisions and generation costs can be directly or 
indirectly affected by movements in the price of natural gas, oil and coal. We have some natural offsets across our 
businesses such that low commodity prices may benefit certain businesses and be a cost to others. Exposures are 
not perfectly linear or symmetric. The sensitivities are affected by a number of local or indirect market factors. 
Examples of these factors include hydrology, local energy market supply/demand balances, regional fuel supply 
issues, regional competition, bidding strategies and regulatory interventions such as price caps. Operational 
flexibility changes the shape of our sensitivities. For instance, certain power plants may limit downside exposure by 
reducing dispatch in low market environments. Volume variation also affects our commodity exposure. The volume 
sold under contracts or retail concessions can vary based on weather and economic conditions resulting in a higher 
or lower volume of sales in spot markets. Thermal unit availability and hydrology can affect the generation output 
available for sale and can affect the marginal unit setting power prices.

In the US SBU, the generation businesses are largely contracted but may have residual risk to the extent 

contracts are not perfectly indexed to the business drivers. IPL primarily generates energy to meet its retail 
customer demand however it opportunistically sells surplus economic energy into wholesale markets at market 
prices. Additionally, at DPL, competitive retail markets permit our customers to select alternative energy suppliers or 
elect to remain in aggregated customer pools for which energy is supplied by third party suppliers through a 
competitive auction process. DPL participates in these auctions held by other utilities and sells the remainder of its 
economic energy into the wholesale market. Given that natural gas-fired generators generally get energy prices for 
many markets, higher natural gas prices tend to expand our coal fixed margins. Our non-contracted generation 
margins are impacted by many factors including the growth in natural gas-fired generation plants, new energy 
supply from renewable sources, and increasing energy efficiency.

In the Andes SBU, our business in Chile owns assets in the central and northern regions of the country and 

has a portfolio of contract sales in both. In the central region, the contract sales generally cover the efficient 
generation from our coal-fired and hydroelectric assets. Any residual spot price risk will primarily be driven by the 
amount of hydrological inflows. In the case of low hydroelectric generation, spot price exposure is capped by the 
ability to dispatch our natural gas/diesel assets the price of which depends on fuel pricing at the time required. 
There is a small amount of coal generation in the northern region that is not covered by the portfolio of contract 
sales and therefore subject to spot price risk. In both regions, generators with oil or oil-linked fuel generally set 
power prices. In Colombia, we operate under a short-term sales strategy and have commodity exposure to 
unhedged volumes. Because we own hydroelectric assets there, contracts are not indexed to fuel.

In the Brazil SBU, the hydroelectric generating facility is covered by contract sales. Under normal hydrological 

volatility, spot price risk is mitigated through a regulated sharing mechanism across all hydroelectric generators in 
the country. Under drier conditions, the sharing mechanism may not be sufficient to cover the business' contract 
position, and therefore it may have to purchase power at spot prices driven by the cost of thermal generation. 

In the MCAC SBU, our businesses have commodity exposure on unhedged volumes. Panama is highly 
contracted under a portfolio of fixed volume contract sales. To the extent hydrological inflows are greater than or 
less than the contract sales volume, the business will be sensitive to changes in spot power prices which may be 
driven by oil prices in some time periods. In the Dominican Republic, we own natural gas-fired assets contracted 
under a portfolio of contract sales and a coal-fired asset contracted with a single contract, and both contract and 
spot prices may move with commodity prices. Additionally, the contract levels do not always match our generation 
availability and our assets may be sellers of spot prices in excess of contract levels or a net buyer in the spot 
market to satisfy contract obligations.

In the Europe SBU, our Kilroot facility operates on a short-term sales strategy. To the extent that sales are 

unhedged, the commodity risk at our Kilroot business is to the clean dark spread, which is the difference between 
electricity price and our coal-based variable dispatch cost including emissions. Natural gas-fired generators set 
power prices for many periods, so higher natural gas prices generally expand margins and higher coal or emissions 
prices reduce them. Similarly, increased wind generators displaces higher cost generation, reducing Kilroot's 
margins, and vice versa.

In the Asia SBU, our Masinloc business is a coal-fired generation facility which hedges its output under a 
portfolio of contract sales that are indexed to fuel prices, with generation in excess of contract volume or shortfalls 

123

of generation relative to contract volumes settled in the spot market. Low oil prices may be a driver of margin 
compression since oil affects spot power sale prices sold in the spot market. Our Mong Duong business has 
minimal exposure to commodity price risk as it has no merchant exposure and fuel is subject to a pass-through 
mechanism.

Foreign Exchange Rate Risk — In the normal course of business, we are exposed to foreign currency risk 
and other foreign operations risks that arise from investments in foreign subsidiaries and affiliates. A key component 
of these risks stems from the fact that some of our foreign subsidiaries and affiliates utilize currencies other than our 
consolidated reporting currency, the U.S. Dollar ("USD"). Additionally, certain of our foreign subsidiaries and 
affiliates have entered into monetary obligations in the USD or currencies other than their own functional currencies. 
We have varying degrees of exposure to changes in the exchange rate between the USD and the following 
currencies: Argentine Peso, British Pound, Brazilian Real, Chilean Peso, Colombian Peso, Dominican Peso, Euro, 
Indian Rupee, Kazakhstan Tenge, Mexican Peso and Philippine Peso. These subsidiaries and affiliates have 
attempted to limit potential foreign exchange exposure by entering into revenue contracts that adjust to changes in 
foreign exchange rates. We also use foreign currency forwards, swaps and options, where possible, to manage our 
risk related to certain foreign currency fluctuations.

AES enters into cash flow hedges to protect economic value of the business and minimize impact of foreign 
exchange rate fluctuations to AES portfolio. While protecting cash flows, the hedging strategy is also designed to 
reduce forward looking earnings foreign exchange volatility. Due to variation of timing and amount between cash 
distribution and earnings exposure, the hedge impact may not fully cover the earnings exposure on a realized basis 
which could result in greater volatility in earnings. The largest foreign exchange risks over a 12-month forward-
looking period stem from the following currencies: Brazilian Real, Euro, Colombian Peso, British Pound, and 
Kazakhstan Tenge. As of December 31, 2016, assuming a 10% USD appreciation, cash distributions attributable to 
foreign subsidiaries exposed to movement in the exchange rate of the Brazilian Real and Euro each is projected to 
be reduced by $5 million. Colombian Peso, Kazakhstan Tenge and British Pound - less than $5 million for 2017. 
These numbers have been produced by applying a one-time 10% USD appreciation to forecasted exposed cash 
distributions for 2017 coming from the respective subsidiaries exposed to the currencies listed above, net of the 
impact of outstanding hedges and holding all other variables constant. The numbers presented above are net of 
any transactional gains/losses. These sensitivities may change in the future as new hedges are executed or 
existing hedges are unwound. Additionally, updates to the forecasted cash distributions exposed to foreign 
exchange risk may result in further modification. The sensitivities presented do not capture the impacts of any 
administrative market restrictions or currency inconvertibility.

The foreign exchange sensitivities included above have been calculated based on the underlying cash 
distribution exposures. This is different than the prior period’s disclosure, which was based on earnings, as a result 
of a change in AES’ foreign exchange hedging strategy in 2016. The table below provides a comparison of the 
earnings based sensitivity approached used in the 2015 Form 10-K for both FY2016 and FY2017.

Interest Rate Risks — We are exposed to risk resulting from changes in interest rates as a result of our 

issuance of variable and fixed-rate debt, as well as interest rate swap, cap, floor and option agreements.

Decisions on the fixed-floating debt mix are made to be consistent with the risk factors faced by individual 

businesses or plants. Depending on whether a plant's capacity payments or revenue stream is fixed or varies with 
inflation, we partially hedge against interest rate fluctuations by arranging fixed-rate or variable-rate financing. In 
certain cases, particularly for non-recourse financing, we execute interest rate swap, cap and floor agreements to 
effectively fix or limit the interest rate exposure on the underlying financing. Most of our interest rate risk is related to 
non-recourse financings at our businesses. 

As of December 31, 2016, the portfolio's pretax earnings exposure for 2017 to a one time 100-basis-point 
increase in interest rates for our Argentine Peso, Brazilian Real, Colombian Peso, Euro, Kazakhstani Tenge and 
USD denominated debt would be approximately $25 million on interest expense for the debt denominated in these 
currencies. These amounts do not take into account the historical correlation between these interest rates.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

The Board of Directors and Stockholders of The AES Corporation:

We have audited the accompanying consolidated balance sheets of The AES Corporation as of December 31, 
2016 and 2015, and the related consolidated statements of operations, comprehensive income, changes in equity, 
and cash flows for each of the three years in the period ended December 31, 2016. Our audits also included the 
financial statement schedules listed in the Index at Item 15(a). These financial statements and schedules are the 
responsibility of the Company’s management. Our responsibility is to express an opinion on these financial 
statements and schedules based on our audits. 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board 

(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about 
whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the 
accounting principles used and significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the 
consolidated financial position of The AES Corporation at December 31, 2016 and 2015, and the consolidated 
results of its operations and its cash flows for each of the three years in the period ended December 31, 2016, in 
conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement 
schedules, when considered in relation to the basic financial statements taken as a whole, present fairly in all 
material respects the information set forth therein.

As discussed in Note 1 to the consolidated financial statements, the Company changed its requirements for 
reporting discontinued operations as a result of the adoption of the amendments to the FASB Accounting Standards 
Codification resulting from Accounting Standards Update No. 2014-08, “Reporting Discontinued Operations and 
Disclosures of Disposals of Components of an Entity,” effective July 1, 2014. Also, the Company changed its 
classification of debt issuance costs as a result of the adoption of the amendments to the FASB Accounting 
Standards Codification resulting from Accounting Standards Update No. 2015-03 and No. 2015-15, “Interest - 
Imputation of Interest (Subtopic 835-30),” effective January 1, 2016. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 

(United States), The AES Corporation’s internal control over financial reporting as of December 31, 2016, based on 
criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations 
of the Treadway Commission (2013 framework) and our report dated February 24, 2017 expressed an unqualified 
opinion thereon.

THE AES CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 2016, 2015, AND 2014

1. GENERAL AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The AES Corporation is a holding company (the "Parent Company") that through its subsidiaries and affiliates, 

(collectively, "AES" or "the Company") operates a geographically diversified portfolio of electricity generation and 
distribution businesses. Generally, given this holding company structure, the liabilities of the individual operating 
entities are non-recourse to the parent and are isolated to the operating entities. Most of our operating entities are 
structured as limited liability entities, which limit the liability of shareholders. The structure is generally the same 
regardless of whether a subsidiary is consolidated under a voting or variable interest model.

PRINCIPLES OF CONSOLIDATION — The Consolidated Financial Statements of the Company include the 
accounts of The AES Corporation and its subsidiaries, which are the entities that it controls. Furthermore, variable 
interest entities ("VIEs") in which the Company has a variable interest have been consolidated when the Company 
is the primary beneficiary and thus controls the VIE. Intercompany transactions and balances are eliminated in 
consolidation. Investments in entities where the Company has the ability to exercise significant influence, but not 
control, are accounted for using the equity method of accounting. 

DP&L, our utility in Ohio, has undivided interests in five generation facilities and numerous transmission 

facilities. These undivided interests in jointly-owned facilities are accounted for on a pro-rata basis in our 
consolidated financial statements. Certain expenses, primarily fuel costs for the generating units, are allocated to 
the joint owners based on their energy usage. The remaining expenses, investments in fuel inventory, plant 
materials and operating supplies and capital additions are allocated to the joint owners in accordance with their 
respective ownership interests. See Note 3—Property, Plant and Equipment for additional details.

USE OF ESTIMATES — The preparation of these consolidated financial statements in conformity with 
accounting principles generally accepted in the United States of America ("GAAP") requires the Company to make 
estimates and assumptions that affect reported amounts of assets and liabilities and disclosures of contingent 
assets and liabilities at the date of the consolidated financial statements, as well as the reported amounts of 
revenue and expenses during the reporting period. Actual results could differ from those estimates. Items subject to 
such estimates and assumptions include: the carrying amount and estimated useful lives of long-lived assets; asset 
retirement obligations; impairment of goodwill, long-lived assets and equity method investments; valuation 
allowances for receivables and deferred tax assets; the recoverability of regulatory assets; the estimation of 
regulatory liabilities; the fair value of financial instruments; the fair value of assets and liabilities acquired in a 
business combination; the measurement of noncontrolling interest using the hypothetical liquidation at book value 
("HLBV") method for certain renewable generation partnerships; the determination of whether a sale of 
noncontrolling interests is considered to be a sale of in-substance real estate (as opposed to an equity transaction); 
pension liabilities; environmental liabilities; and potential litigation claims and settlements.

DISCONTINUED OPERATIONS — Effective July 1, 2014, the Company prospectively adopted Accounting 

Standards Update ("ASU") No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and 
Equipment (Topic 360): Reporting discontinued Operations and Disclosures of Disposals of Components of an 
Entity, which significantly changed the prior accounting guidance on discontinued operations. Under ASU No. 
2014-08, only those disposals of components of an entity that represent a strategic shift that has (or a held-for-sale 
business that will have) a major effect on an entity's operations and financial results are reported as discontinued 
operations. Amongst other changes: equity method investments that were previously scoped-out of the discontinued 
operations accounting guidance are now included in the scope; a business can meet the criteria to be classified as 
held-for-sale upon acquisition and be reported in discontinued operations; and components where an entity retains 
significant continuing involvement or where operations and cash flows will not be eliminated from ongoing 
operations as a result of a disposal transaction can meet the definition of discontinued operations. Additionally, 
where summarized amounts are presented on the face of the financial statements, reconciliations of those amounts 
to major classes of line items are also required. ASU No. 2014-08 requires additional disclosures for individually 
material components that do not meet the definition of discontinued operations. Prior to the adoption of ASU 
2014-08 we had classified certain business as discontinued operations that would not meet the criteria under the 
current standard. See Note 23—Dispositions for further information.

Prior to July 1, 2014, a discontinued operation was a component of the Company that either had been 

disposed of or was classified as held-for-sale and where the Company did not expect to have significant cash flows 
from or significant continuing involvement with the component as of one year after its disposal or sale. A component 

131

 
THE AES CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2016, 2015, AND 2014

was comprised of operations and cash flows that could be clearly distinguished, operationally and for financial 
reporting purposes, from the rest of the Company. 

Prior period amounts in the statement of operations are retrospectively revised to reflect the businesses 

determined to be discontinued operations. The cash flows of businesses that are determined to be discontinued 
operations or held-for-sale are included within the relevant categories within operating, investing and financing 
activities. The aggregate amount of cash flows is offset by the net increase or decrease in cash of discontinued and 
held-for-sale businesses, which is presented as a separate line item in the Consolidated Statements of Cash Flows. 

When an operation is classified as held-for-sale, the Company recognizes any impairment expense on the 

entire operation, which will include an amount allocable to noncontrolling interests, at the level of the held-for-sale 
operation and/or at a parent entity as applicable. However, any gain or loss on the completion of a disposal 
transaction is fully allocated to AES and to its noncontrolling interests at a parent entity level, given that the 
operational level noncontrolling interests have been removed with deconsolidation of the disposed entity. Assets 
and liabilities of held-for-sale businesses are classified as current when they are expected to be disposed of within 
twelve months.

RECLASSIFICATIONS — To comply with newly adopted accounting standards, certain prior period amounts 

in the consolidated financial statements have been reclassified to conform to the current presentation. Deferred 
financing costs were reclassified from the Other current assets and Other noncurrent assets lines to the current and 
noncurrent Non-recourse debt lines, respectively, in the Consolidated Balance Sheet for the year ended December 
31, 2015. Additionally, amounts relating to capitalized software were reclassified from Electric generation, 
distribution assets and other line to Other intangible assets, net of amortization line on the Consolidated Balance 
sheet for the year ended December 31, 2015. See further detail in the new accounting pronouncements discussion.

FAIR VALUE — Fair value is the price that would be received to sell an asset or paid to transfer a liability in an 
orderly, hypothetical transaction between market participants at the measurement date, or exit price. The Company 
applies the fair value measurement accounting guidance to financial assets and liabilities in determining the fair 
value of investments in marketable debt and equity securities, included in the Consolidated Balance Sheet line 
items Short-term investments and Other assets (noncurrent); derivative assets, included in Other current assets and 
Other assets (noncurrent); and, derivative liabilities, included in Accrued and other liabilities (current) and Other 
long-term liabilities. The Company applies the fair value measurement guidance to nonfinancial assets and liabilities 
upon the acquisition of a business or in conjunction with the measurement of an asset retirement obligation or a 
potential impairment loss on an asset group or goodwill under the accounting guidance for the impairment of long-
lived assets or goodwill.

The Company makes assumptions about what market participants would assume in valuing an asset or 

liability based on the best information available. These factors include nonperformance risk (the risk that the 
obligation will not be fulfilled) and credit risk of the subsidiary (for liabilities) and of the counterparty (for assets). The 
Company is prohibited from including transaction costs and any adjustments for blockage factors in determining fair 
value. The principal or most advantageous market is considered from the perspective of the subsidiary owning the 
asset or with the liability.

Fair value is based on observable market prices where available. Where they are not available, specific 
valuation models and techniques are applied depending on what is being fair valued. These models and techniques 
maximize the use of observable inputs and minimize the use of unobservable inputs. The process involves varying 
levels of management judgment, the degree of which is dependent on price transparency and complexity. An 
asset's or liability's level within the fair value hierarchy is based on the lowest level of input significant to the fair 
value measurement, where Level 1 is the highest and Level 3 is the lowest. The three levels are defined as follows:

•  Level 1 — unadjusted quoted prices in active markets accessible by the Company for identical assets or 

liabilities. Active markets are those in which transactions for the asset or liability occur with sufficient frequency 
and volume to provide pricing information on an ongoing basis.

•  Level 2 — pricing inputs other than quoted market prices included in Level 1 which are based on observable 

market data, that are directly or indirectly observable for substantially the full term of the asset or liability. These 
include quoted market prices for similar assets or liabilities, quoted market prices for identical or similar assets in 
markets that are not active, adjusted quoted market prices, inputs from observable data such as interest rate and 
yield curves, volatilities or default rates observable at commonly quoted intervals or inputs derived from 
observable market data by correlation or other means. 

132

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2016, 2015, AND 2014

•  Level 3 — pricing inputs that are unobservable from objective sources. Unobservable inputs are only used to the 
extent observable inputs aren't available. These inputs maintain the concept of an exit price from the perspective 
of a market participant and reflect assumptions of other market participants. The Company considers all market 
participant assumptions that are available without unreasonable cost and effort. These are given the lowest 
priority and are generally used in internally developed methodologies to generate management's best estimate of 
the fair value when no observable market data is available. 

Any transfers between all levels within the fair value hierarchy levels are recognized at the end of the reporting 

period.

CASH AND CASH EQUIVALENTS — The Company considers unrestricted cash on hand, deposits in banks, 

certificates of deposit and short-term marketable securities with original maturities of three months or less to be 
cash and cash equivalents. The carrying amounts of such balances approximate fair value.

RESTRICTED CASH AND DEBT SERVICE RESERVES — These include cash balances which are restricted 

as to withdrawal or usage by the subsidiary that owns the cash. The nature of restrictions includes restrictions 
imposed by financing agreements such as security deposits kept as collateral, debt service reserves, maintenance 
reserves, contractual terms and others, as well as restrictions imposed by agreements related to the sales of 
businesses or long-term PPAs.

INVESTMENTS IN MARKETABLE SECURITIES — The Company's marketable investments are primarily 
unsecured debentures, certificates of deposit, government debt securities and money market funds. Short-term 
investments consist of marketable equity securities and debt securities with original maturities in excess of three 
months with remaining maturities of less than one year. 

Marketable debt securities that the Company has both the positive intent and ability to hold to maturity are 
classified as held-to-maturity and are carried at amortized cost. Other marketable securities that the Company does 
not intend to hold to maturity are classified as available-for-sale or trading and are carried at fair value. Available-for-
sale investments are fair valued at the end of each reporting period where the unrealized gains or losses are 
reflected in AOCL, a separate component of equity.

Investments classified as trading are fair valued at the end of each reporting period through the Consolidated 
Statements of Operations. Interest and dividends on investments are reported in interest income and other income, 
respectively. Gains and losses on sales of investments are determined using the specific identification method.

ACCOUNTS AND NOTES RECEIVABLE AND ALLOWANCE FOR DOUBTFUL ACCOUNTS — Accounts 

and notes receivable are carried at amortized cost. The Company periodically assesses the collectability of 
accounts receivable, considering factors such as specific evaluation of collectability, historical collection experience, 
the age of accounts receivable and other currently available evidence of the collectability, and records an allowance 
for doubtful accounts for the estimated uncollectible amount as appropriate. Certain of our businesses charge 
interest on accounts receivable either under contractual terms or where charging interest is a customary business 
practice. In such cases, interest income is recognized on an accrual basis. When the collection of such interest is 
not reasonably assured, interest income is recognized as cash is received. Individual accounts and notes receivable 
are written off when they are no longer deemed collectible.

INVENTORY — Inventory primarily consists of fuel and other raw materials used to generate power, and spare 

parts and supplies used to maintain power generation and distribution facilities. Inventory is carried at lower of cost 
or market. Cost is the sum of the purchase price and incidental expenditures and charges incurred to bring the 
inventory to its existing condition or location. Costs of inventory are valued primarily using the average cost method. 
Generally, the carrying amount of fuel inventory is reduced to market value if the market value of inventory has 
declined and it is expected that the carrying amount of inventory, in its use in the ordinary course of business, will 
not be recovered through revenue earned from the generation of power. The carrying amount of spare parts and 
supplies is typically reduced only in instances where the items are considered obsolete.

LONG-LIVED ASSETS — Long-lived assets include property, plant and equipment, assets under capital 

leases and intangible assets subject to amortization (i.e., finite-lived intangible assets).

Property, plant and equipment — Property, plant and equipment are stated at cost, net of accumulated 
depreciation. The cost of renewals and improvements that extend the useful life of property, plant and equipment 
are capitalized.

133

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2016, 2015, AND 2014

Construction progress payments, engineering costs, insurance costs, salaries, interest and other costs directly 

relating to construction in progress are capitalized during the construction period, provided the completion of the 
project is deemed probable, or expensed at the time the Company determines that development of a particular 
project is no longer probable. The continued capitalization of such costs is subject to ongoing risks related to 
successful completion, including those related to government approvals, site identification, financing, construction 
permitting and contract compliance. Construction-in-progress balances are transferred to electric generation and 
distribution assets when an asset group is ready for its intended use. Government subsidies, liquidated damages 
recovered for construction delays and income tax credits are recorded as a reduction to property, plant and 
equipment and reflected in cash flows from investing activities.

Depreciation, after consideration of salvage value and asset retirement obligations, is computed primarily 
using the straight-line method over the estimated useful lives of the assets, which are determined on a composite or 
component basis. Maintenance and repairs are charged to expense as incurred. Capital spare parts, including 
rotable spare parts, are included in electric generation and distribution assets. If the spare part is considered a 
component, it is depreciated over its useful life after the part is placed in service. If the spare part is deemed part of 
a composite asset, the part is depreciated over the composite useful life even when being held as a spare part.

The Company's Brazilian subsidiaries, which include both generation and distribution companies, operate 
under concession contracts. Certain estimates are utilized to determine depreciation expense for the Brazilian 
subsidiaries, including the useful lives of the property, plant and equipment and the amounts to be recovered at the 
end of the concession contract. The amounts to be recovered under these concession contracts are based on 
estimates that are inherently uncertain and actual amounts recovered may differ from those estimates. These 
concession contracts are not within the scope of ASC 853—Service Concession Arrangements.

Intangible Assets Subject to Amortization — Finite-lived intangible assets are amortized over their useful lives 

which range from 3 – 50 years. The Company accounts for purchased emission allowances as intangible assets 
and records an expense when utilized or sold. Granted emission allowances are valued at zero.

Impairment of Long-lived Assets — When circumstances indicate that the carrying amount of long-lived assets 

in a held-for-use asset group may not be recoverable, the Company evaluates the assets for potential impairment 
using internal projections of undiscounted cash flows expected to result from the use and eventual disposal of the 
assets. Events or changes in circumstances that may necessitate a recoverability evaluation may include, but are 
not limited to, adverse changes in the regulatory environment, unfavorable changes in power prices or fuel costs, 
increased competition due to additional capacity in the grid, technological advancements, declining trends in 
demand, or an expectation that it is more likely than not that the asset will be disposed of before the end of its 
previously estimated useful life. If the carrying amount of the assets exceeds the undiscounted cash flows expected 
to result from its use, an impairment expense is recognized for the amount by which the carrying amount of the 
asset group exceeds its fair value. The impairment expense cannot exceed the carrying amount of the long-lived 
assets (but subject to the carrying amount not being reduced below fair value for any individual long-lived asset that 
is determinable without undue cost and effort). For regulated assets where recovery through approved rates is 
probable, an impairment expense could be reduced by the establishment of a regulatory asset. For other regulated 
assets and for non-regulated assets, impairment is recognized as an expense. When long-lived assets meet the 
criteria to be classified as held-for-sale and the carrying amount of the disposal group exceeds its fair value less 
costs to sell, an impairment expense is recognized for the excess up to the carrying amount of the long-lived assets; 
if the fair value of the disposal group subsequently exceeds the carrying amount while the disposal group is still 
held-for-sale, any impairment expense previously recognized will be reversed up to the lower of the prior expense 
or the subsequent excess.

SERVICE CONCESSION ASSETS — Service concession assets are stated at cost, net of accumulated 
amortization, in accordance with ASC 853. Service concession assets represent the cost of all infrastructure to be 
transferred to the public-sector entity grantors at the end of the concession. These costs primarily represent 
construction progress payments, engineering costs, insurance costs, salaries, interest and other costs directly 
relating to construction of the service concession infrastructure. Government subsidies, liquidated damages 
recovered for construction delays and income tax credits are recorded as a reduction to Service Concession Assets. 
Service concession assets are amortized and recognized in earnings as a cost of goods sold as infrastructure 
construction revenue is recognized. Services provided under concession arrangements are recognized on a straight 
line basis.

134

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2016, 2015, AND 2014

DEBT ISSUANCE COSTS — Costs incurred in connection with the issuance of long-term debt are deferred 

and presented as a direct reduction from the face amount of that debt and amortized over the related financing 
period using the effective interest method. Debt issuance costs related to a line-of-credit are deferred and presented 
as an asset and amortized over the related financing period. Make-whole payments in connection with early debt 
retirements are classified as cash flows used in financing activities.

EQUITY METHOD INVESTMENTS — Investments in entities over which the Company has the ability to 
exercise significant influence, but not control, are accounted for using the equity method of accounting and reported 
in Investments in and advances to affiliates on the Consolidated Balance Sheets. The Company periodically 
assesses if there is an indication that the fair value of an equity method investment is less than its carrying amount. 
When an indicator exists, any excess of the carrying amount over its estimated fair value is recognized as 
impairment expense when the loss in value is deemed other-than-temporary and included in Other non-operating 
expense in the Consolidated Statements of Operations. The difference between the carrying amount and our 
underlying equity in the net assets of the investee are accounted for as if the investee were a consolidated 
subsidiary, except that the portion that represents equity method goodwill is not reviewed for impairment like 
consolidated goodwill. Upon acquiring the investment, we determine the fair value of the identifiable assets and 
assumed liabilities and the AES share of the amortization of the basis difference between each fair value and the 
carrying amount of the corresponding asset or liability in the financial statements of the investee. The amortization 
of the basis difference is recognized in our net equity in earnings of affiliates over the life of the asset or liability.

The Company discontinues the application of the equity method when an investment is reduced to zero and 

the Company is not otherwise committed to provide further financial support to the investee. The Company resumes 
the application of the equity method accounting to the extent that net income is greater than the share of net losses 
not previously recorded.

GOODWILL AND INDEFINITE-LIVED INTANGIBLE ASSETS — The Company evaluates goodwill and 

indefinite-lived intangible assets for impairment on an annual basis and whenever events or changes in 
circumstances necessitate an evaluation for impairment. The Company's annual impairment testing date is 
October first.

Goodwill — The Company evaluates goodwill impairment at the reporting unit level, which is an SBU (i.e. an 

operating segment as defined in the segment reporting accounting guidance), or a component (i.e., one level below 
an operating segment). In determining its reporting units, the Company starts with its management reporting 
structure. Operating segments are identified and then analyzed to identify components which make up these 
operating segments. Two or more components are combined into a single reporting unit if they are economically 
similar. Assets and liabilities are allocated to a reporting unit if the assets will be employed by or a liability relates to 
the operations of the reporting unit or would be considered by a market participant in determining its fair value. 
Goodwill resulting from an acquisition is assigned to the reporting units that are expected to benefit from the 
synergies of the acquisition. Generally, each AES business with a goodwill balance constitutes a reporting unit as 
they are not reported to segment management together with other businesses and are not similar to other 
businesses in a segment.

Goodwill is evaluated for impairment either under the qualitative assessment option or the two-step test. If the 

Company qualitatively determines it is more likely than not that the fair value of a reporting unit is greater than its 
carrying amount, the two-step impairment test is unnecessary. Otherwise, goodwill is evaluated for impairment 
using the two-step test, where the carrying amount of a reporting unit is compared to its fair value in Step 1; if the 
fair value exceeds the carrying amount, Step 2 is unnecessary. If the carrying amount exceeds the reporting unit's 
fair value, this could indicate potential impairment and Step 2 of the goodwill evaluation process is required to 
determine if goodwill is impaired and to measure the amount of impairment loss to recognize, if any. When Step 2 is 
necessary, the fair value of individual assets and liabilities is determined using valuations (which in some cases may 
be based in part on third party valuation reports) or other observable sources of fair value, as appropriate. If the 
carrying amount of goodwill exceeds its implied fair value, the excess is recognized as an impairment loss up to the 
carrying amount of the goodwill.

Most of the Company's reporting units are not publicly traded. Therefore, the Company estimates the fair value 

of its reporting units using internal budgets and forecasts, adjusted for any market participants' assumptions and 
discounted at the rate of return required by a market participant. The Company generally considers both market and 
income-based approaches to determine a range of fair value, but typically concludes that the value derived using an 
income-based approach is more representative of fair value due to the lack of direct market comparables. The 

135

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2016, 2015, AND 2014

Company utilizes market data, when available, to corroborate and determine the reasonableness of the fair value 
derived from the income-based discounted cash flow analysis.

Indefinite-Lived Intangible Assets — The Company's indefinite-lived intangible assets primarily include land-

use rights and water rights. These are tested for impairment on an annual basis or whenever events or changes in 
circumstances necessitate an evaluation for impairment. If the carrying amount of an intangible asset exceeds its 
fair value, the excess is recognized as impairment expense. When deemed appropriate, the Company uses the 
qualitative assessment option under the accounting guidance on goodwill and intangible assets to determine 
whether the existence of events or circumstances indicate that it is more likely than not that an intangible asset is 
impaired. If, after assessing the totality of events and circumstances, the Company determines that it is not more 
likely than not that an intangible asset is impaired, no further action is taken. The accounting guidance provides the 
option to bypass the qualitative assessment for any intangible asset in any period and proceed directly to 
performing the quantitative impairment test. 

ACCOUNTS PAYABLE AND OTHER ACCRUED LIABILITIES — Accounts payable consists of amounts due 

to trade creditors related to the Company's core business operations. These payables include amounts owed to 
vendors and suppliers for items such as energy purchased for resale, fuel, maintenance, inventory and other raw 
materials. Other accrued liabilities include items such as income taxes, regulatory liabilities, legal contingencies and 
employee-related costs including payroll, benefits and related taxes.

REGULATORY ASSETS AND LIABILITIES — The Company records assets and liabilities that result from the 

regulated ratemaking process that are not recognized under GAAP for non-regulated entities. Regulatory assets 
generally represent incurred costs that have been deferred due to the future recovery in customer rates being 
probable. Generally, returns earned on regulatory assets are reflected on the Consolidated Statement of Operations 
within Interest Income. Regulatory liabilities generally represent obligations to make refunds to customers. 
Management continually assesses whether the regulatory assets are probable of future recovery and regulatory of 
liabilities are probable of future payment by considering factors such as applicable regulatory changes, recent rate 
orders applicable to other regulated entities and the status of any pending or potential deregulation legislation. If 
future recovery of costs previously deferred ceases to be probable, the related regulatory assets are written off and 
recognized in income from continuing operations.

PENSION AND OTHER POSTRETIREMENT PLANS — The Company recognizes in its Consolidated 

Balance Sheets an asset or liability reflecting the funded status of pension and other postretirement plans with 
current-year changes in actuarial gains or losses recognized in AOCL, except for those plans at certain of the 
Company's regulated utilities that can recover portions of their pension and postretirement obligations through 
future rates. All plan assets are recorded at fair value. AES follows the measurement date provisions of the 
accounting guidance, which require a year-end measurement date of plan assets and obligations for all defined 
benefit plans.

Effective January 1, 2016, the Company applied a disaggregated discount rate approach for determining 

service cost and interest cost for its defined benefit pension plans and postretirement plans in the U.S. and U.K. 
This approach is consistent with the requirements of ASC 715—Compensation—Retirement Benefits and is 
considered to be more precise compared to the aggregated single rate discount approach, which has historically 
been used in the U.S. and U.K., because it is more consistent with the philosophy of a full yield curve valuation. The 
disaggregated rate approach can be applied only in countries with a sufficiently robust yield curve. For countries 
other than the U.S. and U.K., the Company will continue to apply a local government bond yield approach.

The change in discount rate approach in the U.S. and U.K. did not have an impact on the measurement of the 

benefit obligations as of December 31, 2015. The 2016 service costs and interest costs included in Note 14—
Benefit Plans reflect the change in estimate described above. The impact of the change in approach on service 
costs for the U.S. and U.K. plans in 2016 is shown below (in millions):

INCOME TAXES — Deferred tax assets and liabilities are recognized for the future tax consequences 
attributable to differences between the financial statement carrying amounts of the existing assets and liabilities, 

136

THE AES CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2016, 2015, AND 2014

and their respective income tax bases. The Company establishes a valuation allowance when it is more likely than 
not that all or a portion of a deferred tax asset will not be realized. The Company's tax positions are evaluated under 
a more likely than not recognition threshold and measurement analysis before they are recognized for financial 
statement reporting.

Uncertain tax positions have been classified as noncurrent income tax liabilities unless expected to be paid 
within one year. The Company's policy for interest and penalties related to income tax exposures is to recognize 
interest and penalties as a component of the provision for income taxes in the Consolidated Statements of 
Operations.

ASSET RETIREMENT OBLIGATIONS — The Company records the fair value of the liability for a legal 
obligation to retire an asset in the period in which the obligation is incurred. When a new liability is recognized, the 
Company capitalizes the costs of the liability by increasing the carrying amount of the related long-lived asset. The 
liability is accreted to its present value each period and the capitalized cost is depreciated over the useful life of the 
related asset. Upon settlement of the obligation, the Company eliminates the liability and, based on the actual cost 
to retire, may incur a gain or loss.

NONCONTROLLING INTERESTS — Noncontrolling interests are classified as a separate component of 
equity in the Consolidated Balance Sheets and Consolidated Statements of Changes in Equity. Additionally, net 
income and comprehensive income attributable to noncontrolling interests are reflected separately from 
consolidated net income and comprehensive income on the Consolidated Statements of Operations and 
Consolidated Statements of Changes in Equity. Any change in ownership of a subsidiary while the controlling 
financial interest is retained is accounted for as an equity transaction between the controlling and noncontrolling 
interests (unless the transaction qualifies as a sale of in-substance real estate). Losses continue to be attributed to 
the noncontrolling interests, even when the noncontrolling interests' basis has been reduced to zero.

Although, in general, the noncontrolling ownership interest in earnings is calculated based on ownership 

percentage, certain of the Company's businesses are subject to profit-sharing arrangements. These agreements 
exist for certain renewable generation partnerships to designate different allocations of value among investors, 
where the allocations change in form or percentage over the life of the partnership. For these businesses, the 
Company uses the HLBV method when it is a reasonable approximation of the profit-sharing arrangement. HLBV 
uses a balance sheet approach, which measures the Company's share of income or loss by calculating the change 
in the amount of net worth the partners are legally able to claim based on a hypothetical liquidation of the entity at 
the beginning of a reporting period compared to the end of that period.

Equity securities with redemption features that are not solely within the control of the issuer are classified 

outside of permanent equity.  Generally, initial measurement will be at fair value. Subsequent measurement and 
classification vary depending on whether the instrument is probable of becoming redeemable.  Where the equity 
instrument is not probable of becoming redeemable subsequent allocation of income and dividends is classified in 
permanent equity. For those securities where it is probable that the instrument will become redeemable or that are 
currently redeemable, AES recognizes changes in the fair value at each accounting period against retained 
earnings subject to the floor of the initial fair value. Further, the allocation of income and dividends, as well as the 
adjustment to fair value, is classified outside permanent equity. Amounts that are mandatory redeemable are 
classified as a liability. 

FOREIGN CURRENCY TRANSLATION — A business's functional currency is the currency of the primary 

economic environment in which the business operates and is generally the currency in which the business 
generates and expends cash. Subsidiaries and affiliates whose functional currency is a currency other than the 
U.S. dollar translate their assets and liabilities into U.S. dollars at the current exchange rates in effect at the end of 
the fiscal period. Translation adjustments arising from the translation of the balance sheet of such subsidiaries are 
included in AOCL. The revenue and expense accounts of such subsidiaries and affiliates are translated into 
U.S. dollars at the average exchange rates that prevailed during the period. Gains and losses on intercompany 
foreign currency transactions that are long-term in nature and which the Company does not intend to settle in the 
foreseeable future, are also recognized in AOCL. Gains and losses that arise from exchange rate fluctuations on 
transactions denominated in a currency other than the functional currency are included in determining net income. 
Accumulated foreign currency translation adjustments are reclassified from AOCL to net income only when realized 
upon sale or upon complete or substantially complete liquidation of the investment in a foreign entity. The 
accumulated adjustments are included in carrying amounts in impairment assessments where the Company has 
committed to a plan that will cause the accumulated adjustments to be reclassified to earnings.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2016, 2015, AND 2014

REVENUE RECOGNITION — Revenue from utilities is classified as regulated in the Consolidated Statements 

of Operations. Revenue from the sale of energy is recognized in the period during which the sale occurs. The 
calculation of revenue earned but not yet billed is based on the number of days not billed in the month, the 
estimated amount of energy delivered during those days and the estimated average price per customer class for 
that month. Differences between actual and estimated unbilled revenue are usually immaterial. The Company has 
businesses where it sells and purchases power to and from ISOs and RTOs. In those instances, the Company 
accounts for these transactions on a net hourly basis because the transactions are settled on a net hourly basis. 
Revenue from generation businesses is classified as non-regulated and is recognized based upon output delivered 
and capacity provided, at rates as specified under contract terms or prevailing market rates. Certain of the 
Company PPAs meet the definition of an operating lease or contain similar arrangements. Typically, minimum lease 
payments from such PPAs are recognized as revenue on a straight-line basis over the lease term whereas 
contingent rentals are recognized when earned. Revenue is recorded net of any taxes assessed on and collected 
from customers, which are remitted to the governmental authorities.

SHARE-BASED COMPENSATION — The Company grants share-based compensation in the form of stock 
options, restricted stock units, and performance stock units. The expense is based on the grant-date fair value of 
the equity or liability instrument issued and is recognized on a straight-line basis over the requisite service period, 
net of estimated forfeitures. The Company uses a Black-Scholes option pricing model to estimate the fair value of 
stock options granted to its employees.

GENERAL AND ADMINISTRATIVE EXPENSES — General and administrative expenses include corporate 
and other expenses related to corporate staff functions and initiatives, primarily executive management, finance, 
legal, human resources and information systems, which are not directly allocable to our business segments. 
Additionally, all costs associated with corporate business development efforts are classified as general and 
administrative expenses.

DERIVATIVES AND HEDGING ACTIVITIES — Under the accounting standards for derivatives and hedging, 

the Company recognizes all contracts that meet the definition of a derivative, except those designated as normal 
purchase or normal sale at inception, as either assets or liabilities in the Consolidated Balance Sheets and 
measures those instruments at fair value. See the Company's fair value policy and Note 4—Fair Value for additional 
discussion regarding the determination of the fair value. The PPAs and fuel supply agreements entered into by the 
Company are evaluated to determine if they meet the definition of a derivative or contain embedded derivatives, 
either of which require separate valuation and accounting. To be a derivative under the accounting standards for 
derivatives and hedging, an agreement would need to have a notional and an underlying, require little or no initial 
net investment and could be net settled. Generally, these agreements do not meet the definition of a derivative, 
often due to the inability to be net settled. On a quarterly basis, we evaluate the markets for the commodities to be 
delivered under these agreements to determine if facts and circumstances have changed such that the agreements 
could then be net settled and meet the definition of a derivative.

Derivatives primarily consist of interest rate swaps, cross-currency swaps, foreign currency instruments, and 
commodity derivatives. The Company enters into various derivative transactions in order to hedge its exposure to 
certain market risks, primarily interest rate, foreign currency and commodity price risks. Regarding interest rate risk, 
the Company and our subsidiaries generally utilize variable rate debt financing for construction projects and 
operations so interest rate swap, lock, cap, and floor agreements are entered into to manage interest rate risk by 
effectively fixing or limiting the interest rate exposure on the underlying financing and are typically designated as 
cash flow hedges. Regarding foreign currency risk, we are exposed to it as a result of our investments in foreign 
subsidiaries and affiliates that may be impacted by significant fluctuations in foreign currency exchange rates so 
foreign currency options and forwards are utilized, where deemed appropriate, to manage the risk related to these 
fluctuations. Cross-currency swaps are utilized in certain instances to manage the risk related to certain foreign 
currencies and the associated impact on interest and loan principal payments. In addition, certain of our 
subsidiaries have entered into contracts which contain embedded foreign currency derivatives as a result of the 
contracts being denominated in a currency other than the functional or local currency of the parties to the contract. 
Regarding commodity price risk, we are exposed to the impact of market fluctuations in the price of electricity, fuel 
and environmental credits. Although we primarily consist of businesses with long-term contracts or retail sales 
concessions (which provide our distribution businesses with a franchise to serve a specific geographic region), a 
portion of our current and expected future revenues are derived from businesses without significant long-term 
purchase or sales contracts. We use an overall hedging strategy, not just derivatives, to hedge our financial 
performance against the effects of fluctuations in commodity prices.

138

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2016, 2015, AND 2014

The accounting standards for derivatives and hedging enable companies to designate qualifying derivatives as 

hedging instruments based on the exposure being hedged. The Company only has cash flow hedges at this time. 
Changes in the fair value of a derivative that is highly effective, designated and qualifies as a cash flow hedge are 
deferred in AOCL and are recognized into earnings as the hedged transactions affect earnings. Any ineffectiveness 
is recognized in earnings immediately. For all designated and qualifying hedges, the Company maintains formal 
documentation of the hedge and effectiveness testing in accordance with the accounting standards for derivatives 
and hedging. If AES determines that the derivative is no longer highly effective as a hedge, hedge accounting will be 
discontinued prospectively. For cash flow hedges of forecasted transactions, AES estimates the future cash flows of 
the forecasted transactions and evaluates the probability of the occurrence and timing of such transactions. 
Changes in conditions or the occurrence of unforeseen events could require discontinuance of hedge accounting or 
could affect the timing of the reclassification of gains or losses on cash flow hedges from AOCL into earnings.

While derivative transactions are not entered into for trading purposes, some contracts are either not eligible 
or not designated for hedge accounting. Changes in the fair value of derivatives not designated and qualifying as 
cash flow hedges are immediately recognized in earnings. Regardless of when gains or losses on derivatives 
(including all those where the fair value measurement is classified as Level 3) are recognized in earnings, they are 
generally classified as follows: interest expense for interest rate and cross-currency derivatives, foreign currency 
transaction gains or losses for foreign currency derivatives, and non-regulated revenue or non-regulated cost of 
sales for commodity and other derivatives. However, gains and losses on interest rate and cross-currency 
derivatives are classified as foreign currency transaction gains and losses if they offset the remeasurement of the 
foreign currency-denominated debt being hedged by the cross-currency swaps. If the underlying hedged item is 
construction debt, the effective portion of the realized swap payment related to capitalized interest is deferred in 
AOCL, then reclassified to cost of sales to offset depreciation expense over the useful life of the associated asset. 
Any foreign currency remeasurement effects in earnings of the foreign currency denominated debt is offset by a 
reclassification from AOCL. Cash flows arising from derivatives are included in the Consolidated Statements of 
Cash Flows as an operating activity given the nature of the underlying risk being economically hedged and the lack 
of significant financing elements, except that cash flows on designated and qualifying hedges of variable-rate 
interest during construction are classified as an investing activity.

The Company has elected not to offset net derivative positions in the financial statements. Accordingly, the 

Company does not offset such derivative positions against the fair value of amounts (or amounts that approximate 
fair value) recognized for the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral 
(a payable) under master netting arrangements.

(Topic 810)

These standards simplify the presentation of debt issuance costs by
requiring that debt issuance costs related to a tranche of debt be
presented on the balance sheet as a direct deduction from the
carrying amount of that debt, consistent with debt discounts. Debt
issuance costs related to a line-of-credit can still be presented as an

regardless of whether there are any outstanding borrowings on the
line-of-credit arrangement. The recognition and measurement
guidance for debt issuance costs are not affected by the standard.
Transition method: retrospective.

The standard makes targeted amendments to the current
consolidation guidance and ends the deferral granted to investment
companies from applying the VIE guidance. The standard amends the
evaluation of whether (1) fees paid to a decision-maker or service

2016-09, Compensation 
— Stock Compensation 
(Topic 718): 
Improvements to 
Employee Share-Based 
Payment Accounting

The standard simplifies the following aspects of accounting for share-
based payments awards: accounting for income taxes, classification
of excess tax benefits on the statement of cash flows, forfeitures,
statutory tax withholding requirements, classification of awards as
either equity or liabilities and classification of employee taxes paid on
statement of cash flows when an employer withholds shares for tax-
withholding purposes. Transition method: The recording of excess tax
benefits and tax deficiencies arising from vesting or settlement will be
applied prospectively. The elimination of the requirement that excess
tax benefits be realized before they are recognized will be adopted on
a modified retrospective basis with a cumulative adjustment to the
opening balance sheet.

January 1, 
2017. 

The standard creates Topic 842, Leases, which supersedes Topic
840, Leases. It introduces a lessee model that brings substantially all
leases onto the balance sheet while retaining most of the principles of
the existing lessor model in U.S. GAAP and aligning many of those
principles with ASC 606, Revenue from Contracts with Customers.
Transition method: modified retrospective approach with certain
practical expedients.
See discussion of the ASU below:

The primary effect of adoption
will be the recognition of
excess tax benefits in our
provision for income taxes in
the period when the awards
vest or are settled, rather than
in paid-in-capital in the period
when the excess tax benefits
are realized. Upon adoption,
the change will result in a
decrease of approximately $30
million to net deferred tax
liabilities, offset by an increase
to retained earnings. We will
continue to estimate the
number of awards that are
expected to vest in our
determination of the related
periodic compensation cost.
The Company is currently
evaluating the impact of
adopting the standard on its
consolidated financial
statements. The Company
intends to adopt the standard
as of January 1, 2019.
The Company will adopt the
standard on January 1, 2018;
see below for the evaluation of
the impact of its adoption on
the consolidated financial
statements.

ASU 2014-09 and its subsequent corresponding updates provides the principles an entity must apply to 

measure and recognize revenue. The core principle is that an entity shall recognize revenue to depict 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 or services. Amendments to the standard were issued that provide further 
clarification of the principle and to provide certain transition expedients. The standard will replace most existing 
revenue recognition guidance in GAAP, including the guidance on recognizing other income upon the sale or 
transfer of nonfinancial assets (including in-substance real estate).

The standard requires retrospective application and allows either a full retrospective adoption in which all of 
the periods are presented under the new standard or a modified retrospective approach in which the cumulative 
effect of initially applying the guidance is recognized at the date of initial application. We are currently working 
towards adopting the standard using the full retrospective method. However, the company will continue to assess 
this conclusion which is dependent on the final impact to the financial statements. 

In 2016, the company established a cross-functional implementation team and is in the process of evaluating 

changes to our business processes, systems and controls to support recognition and disclosure under the new 
standard. At this time, we do not expect any significant impact on our financial systems as a result of the 
implementation of the new revenue recognition standard.

Given the complexity and diversity of our non-regulated arrangements, the Company is assessing the standard 

on a contract by contract basis and has completed more than half of the total expected effort. Through this 
assessment, the Company has identified certain key issues that we are continuing to evaluate in order to complete 
our assessment of the full population of contracts and be able to assess the overall impact to the financial 
statements. These issues include: the application of the practical expedient for measuring progress toward 
satisfaction of a performance obligation, when variable quantities would be considered variable consideration 
versus an option to acquire additional goods and services, how to measure progress toward completion for a 
performance obligation that is a bundle and application of the standard to contracts that are under the scope of 
Service Concession Arrangements (Topic 853). We are continuing to work with various non-authoritative industry 
groups, and monitoring the FASB and Transition Resource Group (TRG) activity, as we finalize our accounting 
policy on these and other industry specific interpretative issues which is expected in 2017.

The Company's asset retirement obligations primarily include active ash landfills, water treatment basins and 
the removal or dismantlement of certain plants and equipment. The $86 million increase in estimated cash flows for 
2016 is primarily relates to revised estimated closure expenditures and earlier plant closure dates than previously 
forecast at DPL. There were $1 million of legally restricted assets for the year ended December 31, 2016 and $2 
million for the year ended December 31, 2015 for purposes of settling asset retirement obligations.

The fair value of current financial assets and liabilities, debt service reserves and other deposits approximate 

their reported carrying amounts. The estimated fair values of the Company's assets and liabilities have been 
determined using available market information. By virtue of these amounts being estimates and based on 
hypothetical transactions to sell assets or transfer liabilities, the use of different market assumptions and/or 
estimation methodologies may have a material effect on the estimated fair value amounts. 

Valuation Techniques — The fair value measurement accounting guidance describes three main approaches 

to measuring the fair value of assets and liabilities: (1) market approach, (2) income approach and (3) cost 
approach. The market approach uses prices and other relevant information generated from market transactions 
involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert 
future amounts to a single present value amount. The measurement is based on current market expectations of the 
return on those future amounts. The cost approach is based on the amount that would currently be required to 
replace an asset. The Company measures its investments and derivatives at fair value on a recurring basis. 
Additionally, in connection with annual or event-driven impairment evaluations, certain nonfinancial assets and 
liabilities are measured at fair value on a nonrecurring basis. These include long-lived tangible assets (i.e., property, 
plant and equipment), goodwill and intangible assets (e.g., sales concessions, land use rights and water rights, 
etc.). In general, the Company determines the fair value of investments and derivatives using the market approach 
and the income approach, respectively. In the nonrecurring measurements of nonfinancial assets and liabilities, all 
three approaches are considered; however, the value estimated under the income approach is often the most 
representative of fair value. 

Investments — The Company's investments measured at fair value generally consist of marketable debt and 

equity securities. Equity securities are either measured at fair value using quoted market prices, which are 
considered Level 1 measurements in the fair value hierarchy, or measured at fair value based on comparisons to 
market data obtained for similar assets, which are considered Level 2 measurements in the fair value hierarchy. 
Debt securities primarily consist of unsecured debentures, certificates of deposit and government debt securities 
held by our Brazilian subsidiaries. Returns and pricing on these instruments are generally indexed to the CDI rates 
in Brazil. Debt securities are measured at fair value based on comparisons to market data obtained for similar 
assets and are considered Level 2 measurements in the fair value hierarchy.

Derivatives — Any Level 1 derivative instruments are exchange-traded commodity futures for which the pricing is 

observable in active markets, and as such, these are not expected to transfer to other levels. There have been no 
transfers between Level 1 and Level 2. 

For all derivatives, with the exception of any classified as Level 1, the income approach is used, which consists 
of forecasting future cash flows based on contractual notional amounts and applicable and available market data as 
of the valuation date. The most common market data inputs used in the income approach include volatilities, spot 
and forward benchmark interest rates (such as LIBOR and EURIBOR), foreign exchange rates and commodity 
prices. Forward rates with the same tenor as the derivative instrument being valued are generally obtained from 
published sources, with these forward rates being assessed quarterly at a portfolio-level for reasonableness versus 
comparable published information provided from another source. When significant inputs are not observable, the 
Company uses relevant techniques to determine the inputs, such as regression analysis or prices for similarly 
traded instruments available in the market.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2016, 2015, AND 2014

For derivatives for which there is a standard industry valuation model, the Company uses a third-party 

derivative accounting and valuation service provider that uses a standard model and observable inputs to estimate 
the fair value. For these derivatives, the Company performs analytical procedures and makes comparisons to other 
third-party information in order to assess the reasonableness of the fair value. For derivatives for which there is not 
a standard industry valuation model (such as PPAs and fuel supply agreements that are derivatives or include 
embedded derivatives), the Company has created internal valuation models to estimate the fair value, using 
observable data to the extent available. At each quarter-end, the models for the commodity and foreign currency-
based derivatives are generally prepared and reviewed by employees who globally manage the respective 
commodity and foreign currency risks and are analytically reviewed independent of those employees. 

Those cash flows are then discounted using the relevant spot benchmark interest rate (such as LIBOR or 
EURIBOR). The Company then makes a credit valuation adjustment ("CVA") by further discounting the cash flows 
for nonperformance or credit risk based on the observable or estimated debt spread of the Company's subsidiary or 
its counterparty and the tenor of the respective derivative instrument. The CVA for potential future scenarios in 
which the derivative is in an asset is based on the counterparty's credit ratings, credit default swap spreads, and 
debt spreads, as available. The CVA for potential future scenarios in which the derivative is a liability is based on the 
Parent Company's or the subsidiary's current debt spread. In the absence of readily obtainable credit information, 
the Parent Company's or the subsidiary's estimated credit rating (based on applying a standard industry model to 
historical financial information and then considering other relevant information) and spreads of comparably rated 
entities or the respective country's debt spreads are used as a proxy. All derivative instruments are analyzed 
individually and are subject to unique risk exposures. 

The Company's methodology to fair value its derivatives is to start with any observable inputs; however, in 

certain instances the published forward rates or prices may not extend through the remaining term of the contract 
and management must make assumptions to extrapolate the curve, which necessitates the use of unobservable 
inputs, such as proxy commodity prices or historical settlements to forecast forward prices. Specifically, where there 
is limited forward curve data with respect to foreign exchange contracts, beyond the traded points the Company 
utilizes the purchasing power parity approach to construct the remaining portion of the forward curve using relative 
inflation rates. In addition, in certain instances, there may not be market or market-corroborated data readily 
available, requiring the use of unobservable inputs. Similarly, in certain instances, the spread that reflects the credit 
or nonperformance risk is unobservable requiring us to utilize proxy yield curves of similar credit quality. The fair 
value hierarchy of an asset or a liability is based on the level of significance of the input assumptions. An input 
assumption is considered significant if it affects the fair value by at least 10%. Assets and liabilities are classified as 
Level 3 when the use of unobservable inputs is significant. When the use of unobservable inputs is insignificant, 
assets and liabilities are classified as Level 2. Transfers between Level 3 and Level 2 are determined as of the end 
of the reporting period and result from changes in significance of unobservable inputs used to calculate the CVA. 

Debt — Recourse and non-recourse debt are carried at amortized cost. The fair value of recourse debt is 

estimated based on quoted market prices. The fair value of non-recourse debt is estimated differently based upon 
the type of loan. In general, the carrying amount of variable rate debt is a close approximation of its fair value. For 
fixed rate loans, the fair value is estimated using quoted market prices or discounted cash flow ("DCF") analyses. In 
the DCF analysis, the discount rate is based on the credit rating of the individual debt instruments, if available, or 
the credit rating of the subsidiary. If the subsidiary's credit rating is not available, a synthetic credit rating is 
determined using certain key metrics, including cash flow ratios and interest coverage, as well as other industry-
specific factors. For subsidiaries located outside the U.S., in the event that the country rating is lower than the credit 
rating previously determined, the country rating is used for purposes of the DCF analysis. The fair value of recourse 
and non-recourse debt excludes accrued interest at the valuation date. The fair value was determined using 
available market information as of December 31, 2016. The Company is not aware of any factors that would 
significantly affect the fair value amounts subsequent to December 31, 2016.

Nonrecurring Measurements — For nonrecurring measurements derived using the income approach, fair value 
is determined using valuation models based on the principles of DCF. The income approach is most often used in 
the impairment evaluation of long-lived tangible assets, equity method investments, goodwill, and intangible assets. 
The Company uses its internally developed DCF valuation models as the primary means to determine nonrecurring 
fair value measurements though other valuation approaches prescribed under the fair value measurement 
accounting guidance are also considered. Depending on the complexity of a valuation, an independent valuation 
firm may be engaged to assist management in the valuation process. A few examples of input assumptions to such 
valuations include macroeconomic factors such as growth rates, industry demand, inflation, exchange rates and 

144

power and commodity prices. Whenever possible, the Company attempts to obtain market observable data to 
develop input assumptions. Where the use of market observable data is limited or not available for certain input 
assumptions, the Company develops its own estimates using a variety of techniques such as regression analysis 
and extrapolations. 

For nonrecurring measurements derived using the market approach, recent market transactions involving the 

sale of identical or similar assets are considered. The use of this approach is limited because it is often difficult to 
identify sale transactions of identical or similar assets. This approach is used in impairment evaluations of certain 
intangible assets. Otherwise, it is used to corroborate the fair value determined under the income approach. 

For nonrecurring measurements derived using the cost approach, fair value is typically based upon a 
replacement cost approach. Under this approach, the depreciated replacement cost of assets is derived by first 
estimating the current replacement cost of assets and then applying the remaining useful life percentages to such 
costs. Further adjustments for economic and functional obsolescence are made to the depreciated replacement 
cost. This approach involves a considerable amount of judgment, which is why its use is limited to the measurement 
of long-lived tangible assets. Like the market approach, this approach is also used to corroborate the fair value 
determined under the income approach. 

Fair Value Considerations — In determining fair value, the Company considers the source of observable 
market data inputs, liquidity of the instrument, the credit risk of the counterparty and the risk of the Company's or its 
counterparty's nonperformance. The conditions and criteria used to assess these factors are: 

Sources of market assumptions — The Company derives most of its market assumptions from market efficient 

data sources (e.g., Bloomberg and Reuters). To determine fair value, where market data is not readily available, 
management uses comparable market sources and empirical evidence to develop its own estimates of market 
assumptions. 

Market liquidity — The Company evaluates market liquidity based on whether the financial or physical 

instrument, or the underlying asset, is traded in an active or inactive market. An active market exists if the prices are 
fully transparent to market participants, can be measured by market bid and ask quotes, the market has a relatively 
large proportion of trading volume as compared to the Company's current trading volume and the market has a 
significant number of market participants that will allow the market to rapidly absorb the quantity of assets traded 
without significantly affecting the market price. Another factor the Company considers when determining whether a 
market is active or inactive is the presence of government or regulatory controls over pricing that could make it 
difficult to establish a market-based price when entering into a transaction. 

Nonperformance risk — Nonperformance risk refers to the risk that an obligation will not be fulfilled and affects 
the value at which a liability is transferred or an asset is sold. Nonperformance risk includes, but may not be limited 
to, the Company or its counterparty's credit and settlement risk. Nonperformance risk adjustments are dependent 
on credit spreads, letters of credit, collateral, other arrangements available and the nature of master netting 
arrangements. The Company and its subsidiaries are parties to various interest rate swaps and options; foreign 
currency options and forwards; and derivatives and embedded derivatives, which subject the Company to 
nonperformance risk. The financial and physical instruments held at the subsidiary level are generally non-recourse 
to the Parent Company. 

Nonperformance risk on the investments held by the Company is incorporated in the fair value derived from 

quoted market data to mark the investments to fair value. 

Recurring Measurements — The following table presents, by level within the fair value hierarchy, as described 
in Note 1—General and Summary of Significant Accounting Policies, the Company's financial assets and liabilities 
that were measured at fair value on a recurring basis as of the dates indicated (in millions). For the Company's 
investments in marketable debt and equity securities, the security classes presented are determined based on the 
nature and risk of the security and are consistent with how the Company manages, monitors and measures its 
marketable securities:

Nonrecurring Measurements 

When evaluating impairment of goodwill, long-lived assets, discontinued operations, and equity method 
investments, the Company measures fair value using the applicable fair value measurement guidance. Impairment 
expense is measured by comparing the fair value at the evaluation date to their then-latest available carrying 
amount. The following table summarizes major categories of assets and liabilities measured at fair value on a

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2016, 2015, AND 2014

Argentina — Collection of the principal and interest on these receivables is subject to various business risks 
and uncertainties including, but not limited to, the operation of power plants which generate cash for payments of 
these receivables, regulatory changes that could impact the timing and amount of collections, and economic 
conditions in Argentina. The Company monitors these risks, including the credit ratings of the Argentine 
government, on a quarterly basis to assess the collectability of these receivables. The Company accrues interest on 
these receivables once the recognition criteria have been met. The Company's collection estimates are based on 
assumptions that it believes to be reasonable, but are inherently uncertain. Actual future cash flows could differ from 
these estimates. 

 FONINVEMEM Agreements

As a result of energy market reforms in 2004 and 2010, AES Argentina entered into three agreements with the 

Argentine government, referred to as the FONINVEMEM Agreements, to contribute a portion of their accounts 
receivable into a fund for financing the construction of combined cycle and gas-fired plants. These receivables 
accrue interest and are collected in monthly installments over 10 years once the related plant begins operations. In 
addition, AES Argentina receives an ownership interest in these newly built plants once the receivables have been 
fully repaid. 

 FONINVEMEM I and II — The receivables under the first two FONINVEMEM Agreements have been actively 

collected since the related plants commenced operations in 2010. In assessing the collectability of the receivables 
under these agreements, the Company also considers how timely the collections have historically been made in 
accordance with the agreements. 

FONINVEMEM III — The receivables related to the third FONINVEMEM Agreement have been actively 
collected since the related plants commenced operations in 2016. In assessing the collectability of the receivables 
under this agreement, the Company also considers how timely the collections have historically been made in 
accordance with the agreements.

The FONINVEMEM receivables are denominated in Argentine pesos, but indexed to U.S. dollars, which 
represents a foreign currency derivative. As of December 31, 2016 and 2015, the amount of the foreign currency-
related derivative assets associated with the FONINVEMEM financing receivables that were excluded from the 
table above had a fair value of $255 million and $292 million, respectively.

Other Agreements

 In 2013, Resolution No. 95/2013 ("Resolution 95") which developed a new energy regulatory framework that 

applies to all generation companies with certain exceptions became effective. The new regulatory framework 
reimburses fixed and variable costs plus a margin that will depend on the technology and fuel used to generate the 
electricity and the installed capacity of each plant. 

In the fourth quarter of 2014, the Argentine government passed a resolution to contribute outstanding 
Resolution 95 receivables into a trust whereby AES Argentina has committed to install additional capacity into the 
system. CAMMESA will finance the investment utilizing the outstanding receivables as a guarantee.

On July 10, 2015, the Argentine government passed Resolution No. 482/2015 ("Resolution 482") which 

updated the prices of Resolution 529/2014 retroactively to February 1, 2015, and created a new trust called 
FONINVEMEM 2015-2018 in order to invest in new generation plants. AES Argentina and certain Termoandes units 
will receive compensation under this program.

The Company's ownership in Guacolda is held through AES Gener, a 67%-owned consolidated subsidiary. AES Gener owns 50% of Guacolda, resulting in an 
AES effective ownership in Guacolda of 33%. 
OPGC has one coal-fired project under development which is an expansion of our existing OPGC business. The project started construction in April 2014 and 
is expected to begin operations in 2018. 

Guacolda — On September 1, 2015, AES Gener and Global Infrastructure Partners ("GIP") executed a 
restructuring of Guacolda that increased Guacolda's tax basis in certain long-term assets and AES Gener's equity 
investment. As a result, AES Gener recorded $66 million in net equity in earnings of affiliates for the year ended 
December 31, 2015, of which $46 million is attributable to The AES Corporation. 

On April 11, 2014, AES Gener undertook a series of transactions, pursuant to which AES Gener acquired the 
interests that it did not previously own in Guacolda for $728 million and simultaneously sold the ownership interest 
to GIP for $730 million. The transaction provided GIP with substantive participating rights in Guacolda and, as a 
result, the Company continues to account for its investment in Guacolda using the equity method of accounting. At 
no time during this transaction did the Company acquire a non-controlling interest. The cash paid for the acquisition 
is reflected in Acquisitions, net of cash acquired and the cash proceeds from the sale of these ownership interests 
to GIP is reflected in Proceeds from the sale of businesses, net of cash sold, and equity method investments on the 
Consolidated Statement of Cash Flows for the period ended December 31, 2014. 

Silver Ridge Power — On July 2, 2014, the Company closed the sale of its 50% ownership interest in Silver 

Ridge Power, LLC ("SRP") for a purchase price of $179 million, excluding the Company's indirect ownership 
interests in SRP's solar generation businesses in Italy and Spain ("Solar Italy" and "Solar Spain," respectively). As 
part of the sale, the buyer had an option to purchase Solar Italy for additional consideration of $42 million by August 
2015. The buyer exercised its option to purchase Solar Italy on August 31, 2015, and the sale was completed on 
October 1, 2015. On September 24, 2015, the Company completed the sale of Solar Spain. Net proceeds from the 
sale transaction were $31 million and the Company recognized a pretax gain on sale of less than $1 million. Upon 
the completion of the Solar Spain and Solar Italy sale transactions noted above, the Company ceased its 
involvement in SRP's business operations and accounted for these transactions as sales of real estate. 

AES Barry Ltd. — The Company holds a 100% ownership interest in AES Barry Ltd. ("Barry"), a dormant entity 

in the U.K. that disposed of its generation and other operating assets. Due to a debt agreement, no material 
financial or operating decisions can be made without the banks' consent, and the Company does not control Barry. 
As of December 31, 2016 and 2015, other long-term liabilities included $41 million and $49 million related to this 
debt agreement.

Elsta — In 2014, long lived assets within Elsta were determined to not be recoverable and an impairment 

charge of approximately $82 million was recognized. The Company recognized its 50% share, or $41 million, 
through its proportion of the equity earnings in Elsta.

At December 31, 2016, retained earnings included $246 million related to the undistributed earnings of the 

Company's 50%-or-less owned affiliates. Distributions received from these affiliates were $24 million, $18 million, 
and $28 million for the years ended December 31, 2016, 2015, and 2014, respectively. As of December 31, 2016, 
the aggregate carrying amount of our investments in equity affiliates exceeded the underlying equity in their net 
assets by $162 million.

8. OTHER NON-OPERATING EXPENSE

There were no significant non-operating expenses for the years ended December 31, 2016 or 2015.

Entek — During 2014, the Company executed an agreement to sell its 49.62% interest in Entek, an investment 
accounted for under the equity method, for $125 million. Entek consists of natural gas and hydroelectric generation 
facilities, plus a coal-fired development project. The Company determined that there was an other-than-temporary 
decline in the fair value of its equity method investment in Entek and recognized pretax impairment expense of $86 
million. The sale of the Company's interest in Entek closed on December 18, 2014. 

Silver Ridge — During 2014, the Company determined that there was a decline in the fair value of its equity 

method investment in Silver Ridge Power, LLC ("SRP") that was other-than-temporary based on indications about 
the fair value of the projects in Italy and Spain that resulted from actual and proposed changes to tariffs. 
Accordingly, the Company recognized pretax impairment expense of $42 million. The transaction related to our 50% 
ownership interest in SRP closed on July 2, 2014 for $179 million. See Note 7—Investments in and Advances to 
Affiliates of this Form 10-K for further information.

DP&L — During the fourth quarter of 2015, the Company performed the annual goodwill impairment test at its 
DP&L reporting unit and recognized a goodwill impairment expense of $317 million. The reporting unit failed Step 1 
as its fair value was less than its carrying amount, which was primarily due to a decrease in forecasted dark 
spreads that were driven by decreases in projected forward power prices, and lower than expected revenues from a 

152

 
 
THE AES CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2016, 2015, AND 2014

new CP product. The fair value of the reporting unit was determined under the income approach using a discounted 
cash flow valuation model. The significant assumptions included within the discounted cash flow valuation model 
were forward commodity price curves, the amount of non-bypassable charges from the pending ESP, expected 
revenues from the new CP product, and planned environmental expenditures. In Step 2, goodwill was determined to 
have an implied negative fair value after the hypothetical purchase price allocation under the accounting guidance 
for business combinations; therefore, a full impairment of the remaining goodwill balance of $317 million was 
recognized. DP&L is reported in the US SBU reportable segment.

Distributed Energy — During the first quarter of 2015, the Company completed the acquisition of 100% of the 

common stock of Main Street Power Company, Inc (subsequently renamed Distributed Energy). The transaction 
included recognition of $16 million of goodwill and is reported in the US SBU reportable segment. See Note 24—

Past expenditures on which the Company does not earn a rate of return.

Our regulatory assets primarily consist of costs that are generally non-controllable, such as purchased 
electricity, energy transmission, the difference between actual fuel costs and the fuel costs recovered in the tariffs, 
and other sector costs. These costs are recoverable or refundable as defined by the laws and regulations in our 
various markets. Our regulatory assets also include defined pension and postretirement benefit obligations equal to 
the previously unrecognized actuarial gains and losses and prior services costs that are expected to be recovered 
through future rates. Other current and noncurrent regulatory assets primarily consist of:

•  Unamortized carrying charges, certain environmental costs, and demand charges at IPL and DPL.

•  Unamortized premiums reacquired or redeemed on long term debt at IPL and DPL, which are amortized over the 

lives of the original issuances.

•  Unrecovered fuel and purchased power costs at IPL and DPL.

Other current regulatory assets that did not earn a rate of return were $34 million and $8 million, as of 
December 31, 2016 and 2015, respectively. Other noncurrent regulatory assets that did not earn a rate of return 
were $138 million and $237 million, as of December 31, 2016 and 2015, respectively. 

Our regulatory liabilities primarily consist of obligations for removal costs which do not have an associated

legal retirement obligation, as well as obligations established by ANEEL in Brazil associated with electric utility 
concessions and represent amounts received from customers or donations not subject to return. These donations 
are allocated to support energy network expansion and to improve utility operations to meet customers' needs. The 
term of the obligation is established by ANEEL and settlement will occur when the electric utility concessions end. 

Other current and noncurrent regulatory liabilities primarily consist of amounts related to rider over collection at 
DPL and liabilities owed to electricity generators due to variance in energy prices during rationing periods known as 
"Free Energy" at Eletropaulo. Our Brazilian subsidiaries are authorized to refund this cost associated with monthly 
energy price variances between the wholesale energy market prices owed to the power generation plants producing 
Free Energy and the capped price reimbursed by the local distribution companies which are passed through to the 
final customers through energy tariffs.

In the accompanying Consolidated Balance Sheets the current regulatory assets and liabilities are recorded in 

Other current assets and Accrued and other liabilities, respectively, and the noncurrent regulatory assets and 
liabilities are recorded in Other noncurrent assets and Other noncurrent liabilities, respectively. The following table

The interest rate on variable rate debt represents the total of a variable component that is based on changes in an interest rate index and of a fixed 
component. The Company has interest rate swaps and option agreements in an aggregate notional principal amount of approximately $3.6 billion on non-
recourse debt outstanding at December 31, 2016. These agreements economically fix the variable component of the interest rates on the portion of the 
variable-rate debt being hedged so that the total interest rate on that debt has been fixed at rates ranging from approximately 1.99% to 8.25%. The debt 
agreements expire at various dates from 2017 through 2073.

(2)  Multilateral loans include loans funded and guaranteed by bilaterals, multilaterals, development banks and other similar institutions.

billion of committed but unused credit facilities available to fund construction and other related costs. Excluding 
these facilities under construction, AES subsidiaries had approximately $2.3 billion in a number of available but 
unused committed credit lines to support their working capital, debt service reserves and other business needs. 
These credit lines can be used for borrowings, letters of credit, or a combination of these uses.

Non-Recourse Debt Covenants, Restrictions and Defaults — The terms of the Company's non-recourse debt 

include certain financial and non-financial covenants. These covenants are limited to subsidiary activity and vary 
among the subsidiaries. These covenants may include, but are not limited to, maintenance of certain reserves and 
financial ratios, minimum levels of working capital and limitations on incurring additional indebtedness.

As of December 31, 2016 and 2015, approximately $535 million and $513 million, respectively, of restricted 

cash was maintained in accordance with certain covenants of the non-recourse debt agreements, and these 
amounts were included within Restricted cash and Debt service reserves and other deposits in the accompanying 
Consolidated Balance Sheets.

Various lender and governmental provisions restrict the ability of certain of the Company's subsidiaries to 

transfer their net assets to the Parent Company. Such restricted net assets of subsidiaries amounted to 
approximately $2.5 billion at December 31, 2016.

The following table summarizes the Company's subsidiary non-recourse debt in default (in millions) as of 

December 31, 2016. Due to the defaults, these amounts are included in the current portion of non-recourse debt:

As of December 31, 2016, none of the defaults are payment defaults. All of the subsidiary non-recourse 
defaults were triggered by failure to comply with other covenants and/or conditions such as (but not limited to) 
failure to meet information covenants, complete construction or other milestones in an allocated time, meet certain 
minimum or maximum financial ratios, or other requirements contained in the non-recourse debt documents of the 
applicable subsidiary.

In the event that there is a default, bankruptcy or maturity acceleration at a subsidiary or group of subsidiaries 

that meets the applicable definition of materiality under the corporate debt agreements of The AES Corporation, 
there could be a cross-default to the Company's recourse debt. Materiality is defined in the Parent's senior secured 
credit facility as having provided 20% or more of the Parent Company's total cash distributions from businesses for 
the four most recently completed fiscal quarters. As of December 31, 2016, none of the defaults listed above 
individually or in the aggregate result in or are at risk of triggering a cross-default under the recourse debt of the 
Parent Company. In the event the Parent Company is not in compliance with the financial covenants of its senior 
secured revolving credit facility, restricted payments will be limited to regular quarterly shareholder dividends at the 
then-prevailing rate. Payment defaults and bankruptcy defaults would preclude the making of any restricted 
payments.

In July 2016, the Company redeemed in full the $181 million balance of its 8.0% outstanding senior unsecured 

notes due 2017. As a result, the Company recognized a loss on extinguishment of debt of $16 million that is 
included in the Consolidated Statement of Operations.

In May 2016, the Company issued $500 million aggregate principal amount of 6.0% senior notes due 2026. 

The Company used these proceeds to redeem, at par, $495 million aggregate principal of its existing LIBOR + 
3.00% senior unsecured notes due 2019. As a result of the latter transaction, the Company recognized a net loss on 
extinguishment of debt of $4 million that is included in the Consolidated Statement of Operations.

In January 2016, the Company redeemed $125 million of its senior unsecured notes outstanding. The 
repayment included a portion of the 7.375% senior notes due in 2021, the 4.875% senior notes due in 2023, the 
5.5% senior notes due in 2024, the 5.5% senior notes due in 2025 and the floating rate senior notes due in 2019. As 
a result of these transactions, the Company recognized a net gain on extinguishment of debt of $7 million that is 
included in the Consolidated Statement of Operations.

In April 2015, the Company issued $575 million aggregate principal amount of 5.50% senior notes due 2025. 

Concurrent with this offering, the Company redeemed via tender offers $344 million aggregate principal of its 
existing 8.00% senior unsecured notes due 2017, and $156 million of its existing 8.00% senior unsecured notes due 
2020. As a result of the latter transaction, the Company recognized a loss on extinguishment of debt of $82 million 
that is included in the Consolidated Statement of Operations. 

In March 2015, the Company redeemed in full the $151 million balance of its 7.75% senior unsecured notes 
due October 2015 and the $164 million balance of its 9.75% senior unsecured notes due April 2016. As a result of 
these transactions, the Company recognized a loss on extinguishment of debt of $23 million that is included in the 
Consolidated Statement of Operations.

Recourse Debt Covenants and Guarantees — The Company's obligations under the senior secured credit 

facility are subject to certain exceptions, secured by (i) all of the capital stock of domestic subsidiaries owned 
directly by the Company and 65% of the capital stock of certain foreign subsidiaries owned directly or indirectly by 
the Company; and (ii) certain intercompany receivables, certain intercompany notes and certain intercompany tax 
sharing agreements.

The senior secured credit facility is subject to mandatory prepayment under certain circumstances, including 

the sale of certain assets. In such a situation, the net cash proceeds from the sale must be applied pro rata to repay 

157

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

the term loan, if any, using 60% of net cash proceeds, reduced to 50% when and if the parent's recourse debt to 
cash flow ratio is less than 5:1. The lenders have the option to waive their pro rata redemption.

The senior secured credit facility contains customary covenants and restrictions on the Company's ability to 
engage in certain activities, including, but not limited to, limitations on other indebtedness, liens, investments and 
guarantees; limitations on restricted payments such as shareholder dividends and equity repurchases; restrictions 
on mergers and acquisitions, sales of assets, leases, transactions with affiliates and off-balance sheet or derivative 
arrangements; and other financial reporting requirements.

The senior secured credit facility also contains financial covenants requiring the Company to maintain certain 
financial ratios including a cash flow to interest coverage ratio, calculated quarterly, which provides that a minimum 
ratio of the Company's adjusted operating cash flow to the Company's interest charges related to recourse debt of 
1.3 times must be maintained at all times and a recourse debt to cash flow ratio, calculated quarterly, which 
provides that the ratio of the Company's total recourse debt to the Company's adjusted operating cash flow must not 
exceed a maximum of 7.5 times.

The terms of the Company's senior unsecured notes and senior secured credit facility contain certain 

covenants including, without limitation, limitation on the Company's ability to incur liens or enter into sale and 
leaseback transactions.

TERM CONVERTIBLE TRUST SECURITIES — In 1999, AES Trust III, a wholly-owned special purpose 
business trust and a VIE, issued approximately 10.35 million of $50 par value TECONS with a quarterly coupon 
payment of $0.844 for total proceeds of $517 million and concurrently purchased $517 million of 6.75% Junior 
Subordinated Convertible Debentures due 2029 (the "6.75% Debentures") issued by AES. The Company 
consolidates AES Trust III in its consolidated financial statements and classifies the TECONS as recourse debt on 
its Consolidated Balance Sheet. The Company's obligations under the 6.75% Debentures and other relevant trust 
agreements, in aggregate, constitute a full and unconditional guarantee by the Company of the TECON Trusts' 
obligations. As of December 31, 2016 and 2015, the sole assets of AES Trust III are the 6.75% Debentures.

AES, at its option, can redeem the 6.75% Debentures which would result in the required redemption of the 

TECONS issued by AES Trust III, currently for $50 per TECON. The TECONS must be redeemed upon maturity of 
the 6.75% Debentures. The TECONS are convertible into the common stock of AES at each holder's option prior to 
October 15, 2029 at the rate of 1.4216, representing a conversion price of $35.17 per share. The maximum number 
of shares of common stock AES would be required to issue should all holders decide to convert their securities 
would be 14.7 million shares.

Dividends on the TECONS are payable quarterly at an annual rate of 6.75%. The Trust is permitted to defer 

payment of dividends for up to 20 consecutive quarters, provided that the Company has exercised its right to defer 
interest payments under the corresponding debentures or notes. During such deferral periods, dividends on the 
TECONS would accumulate quarterly and accrue interest, and the Company may not declare or pay dividends on 
its common stock. AES has not exercised the option to defer any dividends at this time and all dividends due under 
the Trust have been paid.

12. COMMITMENTS

LEASES — The Company and its subsidiaries enter into long-term non-cancelable lease arrangements which, 

for accounting purposes, are classified as either an operating lease or capital lease. Operating leases primarily 
include certain transmission lines, office rental and site leases. Operating lease rental expense for the years ended 
December 31, 2016, 2015, and 2014 was $80 million, $59 million and $48 million, respectively. Capital leases 
primarily include transmission lines at our subsidiaries in Brazil, vehicles, and office and other operating equipment. 
Capital leases are recognized in Property, Plant and Equipment within Electric generation, distribution assets and 
other. The gross value of the capital lease assets as of December 31, 2016 and 2015 was $91 million and $67 
million, respectively. The following table shows the future minimum lease payments under operating and capital 
leases for continuing operations together with the present value of the net minimum lease payments under capital 
leases as of December 31, 2016 for 2017 through 2021 and thereafter (in millions):

CONTRACTS — The Company's operating subsidiaries enter into long-term contracts for construction 
projects, maintenance and service, transmission of electricity, operations services and purchase of electricity and 
fuel. In general, these contracts are subject to variable quantities or prices and are terminable only in limited 
circumstances. Electricity purchase contracts primarily include energy auction agreements at our Brazil subsidiaries 
with extended terms through 2028. The following table shows the future minimum commitments for continuing 
operations under these contracts as of December 31, 2016 for 2017 through 2021 and thereafter as well as actual

Guarantees, Letters of Credit — In connection with certain project financings, acquisitions and dispositions, 

power purchases and other agreements, the Parent Company has expressly undertaken limited obligations and 
commitments, most of which will only be effective or will be terminated upon the occurrence of future events. In the 
normal course of business, the Parent Company has entered into various agreements, mainly guarantees and 
letters of credit, to provide financial or performance assurance to third parties on behalf of AES businesses. These 
agreements are entered into primarily to support or enhance the creditworthiness otherwise achieved by a business 
on a stand-alone basis, thereby facilitating the availability of sufficient credit to accomplish their intended business 
purposes. Most of the contingent obligations relate to future performance commitments which the Company or its 
businesses expect to fulfill within the normal course of business. The expiration dates of these guarantees vary from 
less than one year to more than 18 years.

The following table summarizes the Parent Company's contingent contractual obligations as of December 31, 
2016. Amounts presented in the following table represent the Parent Company's current undiscounted exposure to 
guarantees and the range of maximum undiscounted potential exposure. The maximum exposure is not reduced by 
the amounts, if any, that could be recovered under the recourse or collateralization provisions in the guarantees. 
The were no obligations made by the Parent Company for the direct benefit of the lenders associated with the non-
recourse debt of its businesses.

Excludes normal and customary representations and warranties in agreements for the sale of assets (including ownership in associated legal entities) where 
the associated risk is considered to be nominal.

As of December 31, 2016, the Parent Company had no commitments to invest in subsidiaries under 
construction and to purchase related equipment that were not included in the letters of credit discussed above. 
During the year ended December 31, 2016, the Company paid letter of credit fees ranging from 0.2% to 2.5% per 
annum on the outstanding amounts of letters of credit.

Environmental — The Company periodically reviews its obligations as they relate to compliance with 
environmental laws, including site restoration and remediation. As of December 31, 2016 and 2015 the Company 
had recognized liabilities of $12 million and $10 million, respectively, for projected environmental remediation costs. 
Due to the uncertainties associated with environmental assessment and remediation activities, future costs of 
compliance or remediation could be higher or lower than the amount currently accrued. Moreover, where no liability 
has been recognized, it is reasonably possible that the Company may be required to incur remediation costs or 
make expenditures in amounts that could be material but could not be estimated as of December 31, 2016. In 
aggregate, the Company estimates that the range of potential losses related to environmental matters, where 
estimable, to be up to $19 million. The amounts considered reasonably possible do not include amounts accrued as 
discussed above. 

Litigation — The Company is involved in certain claims, suits and legal proceedings in the normal course of 
business. The Company accrues for litigation and claims when it is probable that a liability has been incurred and 
the amount of loss can be reasonably estimated. The Company has evaluated claims in accordance with the 
accounting guidance for contingencies that it deems both probable and reasonably estimable and, accordingly, has 
recorded aggregate liabilities for all claims of approximately $179 million as of December 31, 2016 and 2015. These 
amounts are reported on the Consolidated Balance Sheets within Accrued and other liabilities and Other noncurrent 
liabilities. A significant portion of these accrued liabilities relate to employment, non-income tax and customer 
disputes in international jurisdictions (principally Brazil). Certain of the Company's subsidiaries, principally in Brazil, 
are defendants in a number of labor and employment lawsuits. The complaints generally seek unspecified monetary 
damages, injunctive relief, or other relief. The subsidiaries have denied any liability and intend to vigorously defend 
themselves in all of these proceedings. There can be no assurance that these accrued liabilities will be adequate to 
cover all existing and future claims or that we will have the liquidity to pay such claims as they arise.

Where no accrued liability has been recognized, it is reasonably possible that some matters could be decided 
unfavorably to the Company and could require the Company to pay damages or make expenditures in amounts that 
could be material but could not be estimated as of December 31, 2016. The material contingencies where a loss is 
reasonably possible primarily include claims under financing agreements; disputes with offtakers, suppliers and 
EPC contractors; alleged violation of monopoly laws and regulations; income tax and non-income tax matters with 
tax authorities; and regulatory matters. In aggregate, the Company estimates that the range of potential losses, 
where estimable, related to these reasonably possible material contingencies to be between $1.5 billion and $1.8 
billion. The amounts considered reasonably possible do not include amounts accrued, as discussed above. These 
material contingencies do not include income tax-related contingencies which are considered part of our uncertain 
tax positions.

Regulatory — During 2013, the Company recognized a regulatory liability of $269 million for a contingency 

related to an administrative ruling which required Eletropaulo to refund customers' amounts related to the regulatory 
asset base. In 2014, Eletropaulo started refunding customers as part of the tariff. In January 2015, ANEEL updated 
the tariff to exclude any further customer refunds. On June 30, 2015, ANEEL included in the tariff reset the 
reimbursement to Eletropaulo of these amounts previously refunded to customers to begin in July 2015. During 
2015, as a result of favorable events, management reassessed the contingency and determined that it no longer 
meets the recognition criteria under ASC 450 — Contingencies. Management believes that it is now only reasonably 
possible that Eletropaulo will have to refund these amounts to customers. Accordingly, the Company reversed the 

160

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2016, 2015, AND 2014

remaining regulatory liability for this contingency of $161 million in 2015, which increased Regulated Revenue by 
$97 million and reduced Interest Expense by $64 million. Amounts related to this case are now included as part of 
our reasonably possible contingent range mentioned in the preceding paragraph.

14. BENEFIT PLANS

Defined Contribution Plan — The Company sponsors four defined contribution plans ("the Plans"). Two are for 
U.S. non-union employees, of which one is for employees of the Parent Company and certain U.S. SBU businesses 
and one is for DPL employees. One plan includes both union and non-union employees at IPL. One defined 
contribution plan is for union employees at DPL. The Plans are qualified under section 401 of the Internal Revenue 
Code. All U.S. employees of the Company are eligible to participate in the appropriate Plan except for those 
employees who are covered by a collective bargaining agreement, unless such agreement specifically provides that 
the employee is considered an eligible employee under a Plan. The Plans provide matching contributions in AES 
common stock or cash, other contributions at the discretion of the Compensation Committee of the Board of 
Directors in AES common stock or cash and discretionary tax deferred contributions from the participants. 
Participants are fully vested in their own contributions and the Company's matching contributions. Participants vest 
in other company contributions ratably over a five-year period ending on the fifth anniversary of their hire date. For 
the year ended December 31, 2016, the Company's contributions to the defined contribution plans were 
approximately $15 million, and for the years ended December 31, 2015 and 2014, contributions were $18 million 
and $22 million per year, respectively.

Defined Benefit Plans — Certain of the Company's subsidiaries have defined benefit pension plans covering 
substantially all of their respective employees. Pension benefits are based on years of credited service, age of the 
participant and average earnings. Of the 33 active defined benefit plans as of December 31, 2016, 5 are at 
U.S. subsidiaries and the remaining plans are at foreign subsidiaries .

Includes an inflation factor that is used to calculate future periodic benefit cost, but is not used to calculate the benefit obligation.

The Company establishes its estimated long-term return on plan assets considering various factors, which 

include the targeted asset allocation percentages, historic returns and expected future returns.

The measurement of pension obligations, costs and liabilities is dependent on a variety of assumptions. These 

assumptions include estimates of the present value of projected future pension payments to all plan participants, 
taking into consideration the likelihood of potential future events such as salary increases and demographic 
experience. These assumptions may have an effect on the amount and timing of future contributions.

The assumptions used in developing the required estimates include the following key factors: discount rates; 

salary growth; retirement rates; inflation; expected return on plan assets; and mortality rates.

The effects of actual results differing from the Company's assumptions are accumulated and amortized over 

future periods and, therefore, generally affect the Company's recognized expense in such future periods.

Effective January 1, 2016, the Company applied a disaggregated discount rate approach for determining 

service cost and interest cost for its defined benefit pension plans and postretirement plans in the U.S. and U.K. 
Refer to Note 1—General and Summary of Significant Accounting Policies for further information relating to this 
change in estimate.

Sensitivity of the Company's pension funded status to the indicated increase or decrease in the discount rate 

and long-term rate of return on plan assets assumptions is shown below. Note that these sensitivities may be 
asymmetric and are specific to the base conditions at year-end 2016. They also may not be additive, so the impact 
of changing multiple factors simultaneously cannot be calculated by combining the individual sensitivities shown. 
The funded status as of December 31, 2016 is affected by the assumptions as of that date. Pension expense for 
2016 is affected by the December 31, 2015 assumptions. The impact on pension expense from a one percentage 
point change in these assumptions is shown in the following table (in millions):

Increase of 1% in the discount rate
Decrease of 1% in the discount rate
Increase of 1% in the long-term rate of return on plan assets

The U.S. plans seek to achieve the following long-term investment objectives:

•  maintenance of sufficient income and liquidity to pay retirement benefits and other lump sum payments;
• 
• 
• 

long-term rate of return in excess of the annualized inflation rate;
long-term rate of return, net of relevant fees, that meets or exceeds the assumed actuarial rate; and
long-term competitive rate of return on investments, net of expenses, that equals or exceeds various benchmark 
rates.

The asset allocation is reviewed periodically to determine a suitable asset allocation which seeks to manage 

risk through portfolio diversification and takes into account, among other possible factors, the above-stated 
objectives, in conjunction with current funding levels, cash flow conditions and economic and industry trends. The 
following table summarizes the Company's U.S. plan assets by category of investment and level within the fair value

Equity Transactions with Noncontrolling Interests

Jordan — In February 2016, the Company completed the sale of 40% of its interest in a wholly-owned 

subsidiary in Jordan that owns a controlling interest in the Jordan IPP4 gas-fired plant for $21 million. The 
transaction was accounted for as a sale of in-substance real estate and a pretax gain of $4 million, net of 
transaction costs, was recognized in net income. The cash proceeds from the sale are reflected in Proceeds from 
the sale of businesses, net of cash sold on the Consolidated Statement of Cash Flows for the period ended 
December 31, 2016. After completion of the sale, the Company has a 36% economic interest in Jordan IPP4 and 
will continue to manage and operate the plant, with 40% owned by Mitsui Ltd. and 24% owned by Nebras Power 
Q.S.C. As the Company maintained control after the sale, Jordan IPP4 continues to be consolidated by the 
Company within the Europe SBU reportable segment.

Brazil Reorganization — In 2015, the Company completed a restructuring of Tietê. This transaction resulted in 

no change of ownership or control. The $27 million impact of this equity transaction was recognized in additional 
paid-in capital. 

Gener — In November 2015, the Company sold a 4% stake in AES Gener S.A. ("Gener") through its 99.9% 
owned subsidiary Inversiones Cachagua S.p.A ("Cachagua") for $145 million, net of transaction costs. The sale was 
of previously issued common shares of Gener to certain institutional investors and is not a sale of in-substance real 
estate. While the sale decreased Parent ownership interest from 70.7% to 66.7%, the Parent continues to retain its 
controlling financial interest in the subsidiary. The difference of $24 million between the fair value of the 
consideration received, net of taxes and transaction costs, and the amount by which the NCI is adjusted was 

164

THE AES CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2016, 2015, AND 2014

recognized in additional paid-in capital. No pretax gain or loss was recognized in net income as a result of this 
transaction. 

Dominican Republic — In December 2014 Estrella and Linda Groups, an investor-based group in the 
Dominican Republic acquired 8% noncontrolling interest in our businesses in the Dominican Republic for $83 
million, net of transaction costs, with options to acquire an additional 2% for $24 million at any time between the 
closing date and December 31, 2015, and an additional 10% for $125 million at any time between the closing date 
and December 31, 2017. In December 2015, Estrella and Linda Groups exercised its first call option of additional 
2% for $18 million, net of discount and transaction costs. This resulted in Estrella and Linda Groups having a total of 
10% noncontrolling interest in our businesses in the Dominican Republic. 

 As a result of these transaction, $7 million, net of taxes and transaction costs, was recognized in additional 
paid-in capital at December 31, 2015. No gain or loss was recognized in net income as the sale was not considered 
to be a sale of in-substance real estate. As the Company maintained control after the sale, our businesses in the 
Dominican Republic continue to be consolidated by the Company within the MCAC SBU reportable segment.

Masinloc — On June 25, 2014, the Company executed an agreement to sell approximately 45% of its interest 

in Masin-AES Pte Ltd., a wholly-owned subsidiary that owns the Company's business interests in the Philippines, 
for $453 million, subject to certain purchase price adjustments. On July 15, 2014, the Company completed the 
Masinloc sale transaction and received cumulative net proceeds of $436 million, including $23 million contingent 
upon the achievement of certain restructuring efficiencies. The transaction was accounted for as a sale of in-
substance real estate. Noncontrolling interest of $130 million and a pretax gain on sale of investment of 
approximately $283 million, net of transaction costs, were recognized during the third quarter of 2014. The portion of 
the proceeds related to the contingency has been deferred. 

After completion of the sale, the Company owns a 51% net ownership interest in Masinloc and will continue to 

manage and operate the plant. As the Company maintained control after the sale, Masinloc continues to be 
accounted for as a consolidated subsidiary within the Asia SBU reportable segment.

Deconsolidations

UK Wind — During 2016, the Company determined it no longer had control of its wind development projects in 
the United Kingdom (“UK Wind”) as the Company no longer held seats on the board of directors. In accordance with 
the accounting guidance, UK Wind was deconsolidated and a loss on deconsolidation of $20 million was recorded 
to Gain (loss) on disposal and sale of businesses in the Consolidated Statement of Operations to write off the 
Company’s non-controlling interest in the project. The UK Wind projects were reported in the Europe SBU 
reportable segment.

DECEMBER 31, 2016, 2015, AND 2014

The common stock repurchased has been classified as treasury stock and accounted for using the cost 

method. A total of 156,878,891 and 149,037,831 shares were held as treasury stock at December 31, 2016 and 
2015, respectively. Restricted stock units under the Company's employee benefit plans are issued from treasury 
stock. The Company has not retired any common stock repurchased since it began the Program in July 2010.

16. SEGMENTS AND GEOGRAPHIC INFORMATION 

The segment reporting structure uses the Company's organizational structure as its foundation to reflect how 

the Company manages the businesses internally and is organized by geographic regions which provides a socio-
political-economic understanding of our business. The management reporting structure is organized by six SBUs 
led by our President and Chief Executive Officer: US, Andes, Brazil, MCAC, Europe, and Asia SBUs. Using the 
accounting guidance on segment reporting, the Company determined that it has six operating and six reportable 
segments corresponding to its SBUs.

Corporate and Other — Corporate overhead costs which are not directly associated with the operations of our 

six reportable segments are included in "Corporate and Other." Also included are certain intercompany charges 
such as self-insurance premiums which are fully eliminated in consolidation.

The Company uses Adjusted PTC as its primary segment performance measure. Adjusted PTC, a non-GAAP 
measure, is defined by the Company as pretax income from continuing operations attributable to AES excluding (1) 
unrealized gains or losses related to derivative transactions, (2) unrealized foreign currency gains or losses, (3) 
gains or losses due to dispositions and acquisitions of business interests, (4) losses due to impairments, and (5) 
costs due to the early retirement of debt. The Company has concluded that Adjusted PTC best reflects the 
underlying business performance of the Company and is the most relevant measure considered in the Company's 
internal evaluation of the financial performance of its segments. Additionally, given its large number of businesses 
and complexity, the Company concluded that Adjusted PTC is a more transparent measure that better assists 
investors in determining which businesses have the greatest impact on the Company's results. 

Revenue and Adjusted PTC are presented before inter-segment eliminations, which includes the effect of 
intercompany transactions with other segments except for interest, charges for certain management fees, and the 
write-off of intercompany balances, as applicable. All intra-segment activity has been eliminated within the segment. 
Inter-segment activity has been eliminated within the total consolidated results.

17. SHARE-BASED COMPENSATION

STOCK OPTIONS — AES grants options to purchase shares of common stock under stock option plans to 
employees and non-employee directors. Under the terms of the plans, the Company may issue options to purchase 
shares of the Company's common stock at a price equal to 100% of the market price at the date the option is 
granted. Stock options are generally granted based upon a percentage of an employee's base salary. Stock options 
issued in 2015 and 2014 have a three-year vesting schedule and vest in one-third increments over the three-year 
period. The stock options have a contractual term of ten years. The Company did not issue stock options in 2016. At 
December 31, 2016, approximately 16 million shares were remaining for award under the plans. In all 
circumstances, stock options granted by AES do not entitle the holder the right, or obligate AES, to settle the stock 
option in cash or other assets of AES.

The following table presents the weighted average fair value of each option grant and the underlying weighted 

average assumptions, as of the grant date, using the Black-Scholes option-pricing model:

December 31,
Expected volatility
Expected annual dividend yield
Expected option term (years)

The Company does not discount the grant date fair values to estimate post-vesting restrictions. Post-vesting 

restrictions include black-out periods when the employee is not able to exercise stock options based on their 
potential knowledge of information prior to the release of that information to the public.

cost related to stock options of $1 million is expected to be recognized over a weighted average period of 1 year.

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference 
between the Company's closing stock price on the last trading day of 2016 and the exercise price, multiplied by the 
number of in-the-money options) that would have been received by the option holders had all option holders 
exercised their options on December 31, 2016. The amount of the aggregate intrinsic value will change based on 
the fair market value of the Company's stock.

RESTRICTED STOCK

Restricted Stock Units — The Company issues restricted stock units ("RSUs") under its long-term 

compensation plan. The RSUs are generally granted based upon a percentage of the participant's base salary. The 
units have a three-year vesting schedule and vest in one-third increments over the three-year period. Units granted 
prior to 2011 are required to be held for an additional two years before they can be converted into shares, and thus 
become transferable. There is no such requirement for units granted in 2011 and afterwards. In all circumstances, 
restricted stock units granted by AES do not entitle the holder the right, or obligate AES, to settle the restricted stock 
unit in cash or other assets of AES.

For the years ended December 31, 2016, 2015, and 2014, RSUs issued had a grant date fair value equal to 

the closing price of the Company's stock on the grant date. The Company does not discount the grant date fair 
values to reflect any post-vesting restrictions. RSUs granted to employees during the years ended December 31, 
2016, 2015, and 2014 had grant date fair values per RSU of $9.42, $12.03 and $14.60, respectively.

The following table summarizes the components of the Company's stock-based compensation related to its 

employee RSUs recognized in the Company's consolidated financial statements (in millions):

related to RSUs of $17 million is expected to be recognized over a weighted average period of approximately 
1.8 years. There were no modifications to RSU awards during the year ended December 31, 2016.

The Company initially recognizes compensation cost on the estimated number of instruments for which the 

requisite service is expected to be rendered. In 2016, AES has estimated a weighted average forfeiture rate of 
11.54% for RSUs granted in 2016. This estimate will be revised if subsequent information indicates that the actual 
number of instruments forfeited is likely to differ from previous estimates. Based on the estimated forfeiture rate, the 
Company expects to expense $16 million on a straight-line basis over a three year period related to RSUs granted 
during the year ended December 31, 2016.

The following table summarizes the RSUs that vested and were converted during the periods indicated (RSUs

Performance Stock Units — In 2015 and 2014, the Company issued performance stock units ("PSUs") to 

officers under its long-term compensation plan. PSUs are restricted stock units of which 50% of the units awarded 
include a market condition and the remaining 50% include a performance condition. Vesting will occur if the 
applicable continued employment conditions are satisfied and (a) for the units subject to the market condition the 
total stockholder return on AES common stock exceeds the total stockholder return of the Standard and Poor's 500 
Utilities Sector Index over the three-year measurement period beginning on January 1 of the grant year and ending 
on December 31 of the third year and (b) for the units subject to the performance condition if the Company's actual 
Adjusted EBITDA meets the performance target over the three-year measurement period beginning on January 1 of 
the grant year and ending on December 31 of the third year. The market and performance conditions determine the 
vesting and final share equivalent per PSU and can result in earning an award payout range of 0% to 200%, 
depending on the achievement. PSUs that included a market condition granted during the year ended 
December 31, 2015, and 2014 had a grant date fair value per PSU of $8.22 and $15.19, respectively. 

In 2016, the Company issued PSUs to officers under its long-term compensation plan. Vesting will occur if the 

Company achieves its Proportional Free Cash Flow target over the three-year performance period beginning on 
January 1 of the grant year and ending on December 31 of the third year. The PSUs issued to officers in 2016 had a 
grant date fair value of $9.41 equal to the closing price of the Company's stock on the grant date. The grant date fair 
value is estimated at 100% of the company's closing stock price. The company believes that it's probable that the 
performance condition will be met and will continue to be evaluated throughout the performance period. 

In all circumstances, PSUs granted by AES do not entitle the holder the right, or obligate AES, to settle the 

restricted stock unit in cash or other assets of AES.

The following table summarizes the components of the Company's stock-based compensation related to its 

PSUs recognized in the Company's consolidated financial statements (in millions):

The Company initially recognizes compensation cost on the estimated number of instruments for which the 

requisite service is expected to be rendered. In 2016, AES has estimated a forfeiture rate of 12.28% for PSUs 
granted in 2016. This estimate will be revised if subsequent information indicates that the actual number of 
instruments forfeited is likely to differ from previous estimates. Based on the estimated forfeiture rate, the Company 
expects to expense $6 million on a straight-line basis over a three year period (approximately $2 million per year) 
related to PSUs granted during the year ended December 31, 2016.

The following table summarizes the PSUs that vested and were converted during the periods indicated (PSUs 

in thousands):

Performance Cash Units - In 2016, the Company issued Performance Cash Units ("PCUs") to its officers 

under its long-term compensation plan. The value of these units depends on the total stockholder return on 
AES common stock as compared to the total stockholder return of the Standard and Poor's 500 Utilities Sector 
Index, Standard and Poor's 500 Index and MSCI Emerging Market Index over a three-year measurement period 
beginning on January 1 of the grant year and ending on December 31 of the third year. Since PCUs are settled in 
cash, they qualify for liability accounting and periodic measurement is required. As of December 31, 2016, each 
PCU is valued at $1.04 per unit. The Company expects to expense $7 million on a straight-line basis over a three 
year period (approximately $2 million per year) related to these PCUs.

Colon — During the year ended December 31, 2016, our partner in Colon increased their ownership from 25% 

to 49.9% and made capital contributions of $106 million. Any subsequent adjustments to allocate earnings and 
dividends to our partner, or measure the investment at fair value, will be classified as temporary equity each 
reporting period as it is probable that the shares will become redeemable. 

IPL — IPL had $60 million of cumulative preferred stock outstanding at December 31, 2016 and 2015, which 
represented five series of preferred stock. The total annual dividend requirements were approximately $3 million at 
December 31, 2016 and 2015. Certain series of the preferred stock were redeemable solely at the option of the 
issuer at prices between $100 and $118 per share. Holders of the preferred stock are entitled to elect a majority of 
IPL's board of directors if IPL has not paid dividends to its preferred stockholders for four consecutive quarters. 
Based on the preferred stockholders' ability to elect a majority of IPL's board of directors in this circumstance, the 
redemption of the preferred shares is considered to be not solely within the control of the issuer and the preferred 
stock is considered temporary equity. 

DPL — DPL had $18 million of cumulative preferred stock outstanding as of December 31, 2015, which 

represented three series of preferred stock issued by DP&L, a wholly-owned subsidiary of DPL. The DP&L 
preferred stock was redeemable at DP&L's option as determined by its board of directors at per-share redemption 
prices between $101 and $103 per share, plus cumulative preferred dividends. In addition, DP&L's Amended 
Articles of Incorporation contained provisions that permitted preferred stockholders to elect members of the DP&L 
Board of Directors in the event that cumulative dividends on the preferred stock are in arrears in an aggregate 
amount equivalent to at least four full quarterly dividends. Based on the preferred stockholders' ability to elect 
members of DP&L's board of directors in this circumstance, the redemption of the preferred shares was considered 
to be not solely within the control of the issuer and the preferred stock was considered temporary equity.

In September 2016, it became probable that the preferred shares would become redeemable. As such, the 

Company recorded an adjustment of $5 million to retained earnings to adjust the preferred shares to their 
redemption value of $23 million. In October 2016, DP&L redeemed all of its preferred shares. Upon redemption, the 
preferred shares were no longer outstanding and all rights of the holders thereof as shareholders of DP&L ceased 
to exist. 

IPALCO — In February 2015, CDPQ purchased 15% of AES US Investment, Inc., a wholly-owned subsidiary 
that owns 100% of IPALCO, for $247 million, with an option to invest an additional $349 million in IPALCO through 
2016 in exchange for a 17.65% equity stake. In April 2015, CDPQ invested an additional $214 million in IPALCO, 
which resulted in CDPQ's combined direct and indirect interest in IPALCO of 24.90%. As a result of these 
transactions, $84 million in taxes and transaction costs were recognized as a net decrease to equity. The Company 
also recognized an increase to additional paid-in capital and a reduction to retained earnings of 377 million for the 
excess of the fair value of the shares over their book value. No gain or loss was recognized in net income as the 
transaction was not considered to be a sale of in-substance real estate.

In March 2016, CDPQ exercised its remaining option by investing $134 million in IPALCO, which resulted in 

CDPQ's combined direct and indirect interest in IPALCO of 30%. The Company also recognized an increase to 
additional paid-in capital and a reduction to retained earnings of $84 million for the excess of the fair value of the 
shares over their book value. In June 2016, CDPQ contributed an additional $24 million to IPALCO, with no impact 
to the ownership structure of the investment. Any subsequent adjustments to allocate earnings and dividends to 
CDPQ will be classified as NCI within permanent equity as it is not probable that the shares will become 
redeemable.

During the fourth quarter of 2016, we recognized a full allowance on a non-trade receivable in the MCAC SBU as a result of payment delays and discussions 
with the counterparty. The allowance relates to certain reimbursements the Company was expecting in connection with a legal matter. Management believes 
the counterparty is obligated to pay and plans to continue to attempt to fully collect the non-trade receivable.

Buffalo Gap I — During 2016, the Company tested the recoverability of its long-lived assets at Buffalo Gap I. 

Low wind production during 2016 resulted in management lowering future expectations of production and therefore 
future forecasted revenues. As such this was determined to be an impairment indicator. The Company determined 
that the carrying amount of the asset group was not recoverable. The Buffalo Gap I asset group was determined to 
have a fair value of $36 million using the income approach. As a result, the Company recognized an asset 
impairment expense of $77 million ($23 million attributable to AES). Buffalo Gap I is reported in the US SBU 
reportable segment.

DPL — During the second quarter of 2016, the Company tested the recoverability of its long-lived generation 
assets at DPL. Uncertainty created by the Supreme Court of Ohio’s June 20, 2016 opinion regarding ESP 2, lower 
expectations of future revenue resulting from the most recent PJM capacity auction, and higher anticipated 
environmental compliance costs resulting from third party studies were collectively determined to be an impairment 
indicator for these assets. The Company performed a long-lived asset impairment analysis and determined that the 
carrying amount of Killen, a coal-fired generation facility, and certain DPL peaking generation facilities were not 
recoverable. The Killen and DPL peaking generation asset groups were determined to have a fair value of $84 
million and $5 million, respectively, using the income approach. As a result, the Company recognized a total asset 
impairment expense of $235 million. DPL is reported in the US SBU reportable segment.

During the fourth quarter of 2016, the Company tested the recoverability of its long-lived coal-fired generation 

assets and one gas-fired peaking plant at DPL. Additional uncertainty around the useful life of Stuart and Killen 

174

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2016, 2015, AND 2014

related to the Company’s ESP proceedings, along with lower expected forward dark spreads and capacity prices, 
were collectively determined to be an impairment indicator for these assets. Market information indicating that there 
was a significant decrease in the fair value of Zimmer and Miami Fort was determined to be an indicator of 
impairment for these assets. The lower forward dark spreads and capacity prices, along with the indicators at the 
other coal-fired facilities, collectively, resulted in an indicator of impairment for the Conesville asset group. For the 
gas-fired peaking plant, significant incremental capital expenditures relative to its fair value, and an impairment 
charge taken at this facility in Q2 2016, were collectively determined to be impairment indicators for this asset. The 
Company performed a long-lived asset impairment analysis for each of these asset groups and determined that 
their carrying amounts were not recoverable. The Stuart, Killen, Miami Fort, Zimmer, Conesville and the gas-fired 
peaking plant asset groups were determined to have a fair value of $57 million, $43 million, $36 million, $24 
million, $1 million and $2 million, respectively, using the market approach for Miami Fort and Zimmer and the 
income approach for the remaining asset groups. As a result, the Company recognized a total pre-tax asset 
impairment expense of $624 million. DPL is reported in the US SBU reportable segment.

Buffalo Gap II — During 2016, the Company tested the recoverability of its long-lived assets at Buffalo Gap II. 

Impairment indicators were identified based on a decline in forward power curves. The Company determined that 
the carrying amount was not recoverable. The Buffalo Gap II asset group was determined to have a fair value of 
$92 million using the income approach. As a result, the Company recognized an asset impairment expense of $159 
million ($49 million attributable to AES). Buffalo Gap II is reported in the US SBU reportable segment.

Kilroot — During 2015, the Company tested the recoverability of long-lived assets at Kilroot, a coal- and oil-
fired plant in the U.K., when the regulator established lower capacity prices for the Irish Single Electricity Market. 
The Company determined that the carrying amount of the asset group was not recoverable. The Kilroot asset group 
was determined to have a fair value of $70 million using the income approach. As a result, the Company recognized 
asset impairment expense of $121 million. Kilroot is reported in the Europe SBU reportable segment.

Buffalo Gap III — During 2015, the Company tested the recoverability of its long-lived assets at Buffalo Gap III, 

a wind farm in Texas. Impairment indicators were identified based on a decline in forward power curves coupled 
with the near term expiration of favorable contracted cash flows. The Company determined that the carrying amount 
was not recoverable. The Buffalo Gap III asset group was determined to have a fair value of $118 million using the 
income approach. As a result, the Company recognized asset impairment expense of $116 million. Buffalo Gap III is 
reported in the US SBU reportable segment.

U.K. Wind — During 2015, the Company decided to no longer pursue two wind projects in the U.K. based on 
recent regulatory clarifications specific to these projects, resulting in a full impairment. Impairment indicators were 
also identified at four other wind projects based on their current development status and a reassessment of the 
likelihood that each project would be pursued given aviation concerns, regulatory changes, economic 
considerations and other factors. The Company determined that the carrying amounts of each of these asset 
groups, which totaled $38 million, were not recoverable. In aggregate, the asset groups were determined to have a 
fair value of $1 million using the market approach and, as a result, the Company recognized asset impairment 
expense of $37 million. The U.K. Wind Projects are reported in the Europe SBU reportable segment.

Ebute — During 2014, the Company identified impairment indicators at Ebute in Nigeria, resulting from the 

continued lack of gas supply, the increased likelihood of selling the asset group before the end of its useful life, and 
indications about the potential proceeds that could be received from a future sale. The Company determined that 
the carrying amount of the asset group was not recoverable. The Company recognized asset impairment of $67 
million, which represents the difference between the carrying amount of $103 million and fair value less cost to sell 
of $36 million. In November 2014, the Company completed the sale of its interest in Ebute. See Note 23—
Dispositions for additional details. Prior to its sale, Ebute was reported in the Europe SBU reportable segment.

U.K. Wind (Newfield) — During 2014, the Company tested the recoverability of long-lived assets at its 
Newfield wind development project in the U.K. after their government refused to grant a permit necessary for the 
project to continue. The Company determined that the carrying amount of the asset group was not recoverable. The 
Newfield asset group was determined to have no fair value using the income approach. As a result, the Company 
recognized asset impairment expense of $12 million. U.K. Wind (Newfield) is reported in the Europe SBU reportable 
segment.

East Bend (DP&L) — During 2014, the Company identified impairment indicators at East Bend, a coal-fired 

plant in Ohio jointly owned by DP&L, resulting from the increased likelihood that the asset group would be disposed 

175

prior to the end of its useful life. The Company determined that the carrying amount of the asset group was not 
recoverable. The East Bend asset group was determined to have a fair value of $2 million using the market 
approach, and the Company recognized asset impairment expense of $12 million. The Company's interest in East 
Bend was sold in December 2014. Prior to its sale, East Bend was reported in the US SBU reportable segment.

For 2016, included in the favorable 215% taxes on foreign earnings percentage above is approximately 151% 

related to the current year benefit resulting from a restructuring of one of our Brazilian subsidiaries that increased 
tax basis in long-term assets. The 42% Buffalo Gap impairments item relates to the amounts of impairment 
allocated to noncontrolling interest which is nondeductible.

Included in the favorable 15% 2014 taxes on foreign earnings percentage above is approximately 9% related 

to the sale of approximately 45% of the Company's interest in Masin AES Pte Ltd., which owns the Company's 
interests in the Philippines, and the sale of the Company's interests in four U.K. wind projects. Neither of these 
transactions gave rise to income tax expense.

Chilean Tax Reform — In February 2016, the Chilean government enacted further reforms to its income tax 

laws that resulted in an increase to statutory income tax rates for most of our Chilean businesses from 25% to 
25.5% in 2017 and to 27% for 2018 and future years. The impact of remeasuring deferred taxes to account for the 
enacted change in future applicable income tax rates was recognized as discrete income tax expense in the first 
quarter of 2016, resulting in an increase of $26 million to consolidated income tax expense.

176

THE AES CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2016, 2015, AND 2014

Deferred Income Taxes — Deferred income taxes reflect the net tax effects of (a) temporary differences 

between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for 
income tax purposes and (b) operating loss and tax credit carryforwards. These items are stated at the enacted tax 
rates that are expected to be in effect when taxes are actually paid or recovered.

As of December 31, 2016, the Company had federal net operating loss carryforwards for tax purposes of 

approximately $3.5 billion expiring in years 2021 to 2036. Approximately $88 million of the net operating loss 
carryforward related to stock option deductions will be recognized in additional paid-in capital when realized. The 
Company also had federal general business tax credit carryforwards of approximately $20 million expiring primarily 
from 2021 to 2036, and federal alternative minimum tax credits of approximately $5 million that carry forward 
without expiration. The Company had state net operating loss carryforwards as of December 31, 2016 of 
approximately $9.1 billion expiring in years 2017 to 2036. As of December 31, 2016, the Company had foreign net 
operating loss carryforwards of approximately $3.1 billion that expire at various times beginning in 2017 and some 
of which carry forward without expiration, and tax credits available in foreign jurisdictions of approximately $32 
million, $22 million of which expire in 2021 and $8 million of which carryforward without expiration.

Valuation allowances decreased $18 million during 2016 to $876 million at December 31, 2016. This net 
decrease was primarily the result of valuation allowance releases and foreign exchange gains at certain of our 
Brazil subsidiaries.

Valuation allowances decreased $103 million during 2015 to $894 million at December 31, 2015. This net 
decrease was primarily the result of foreign exchange losses and valuation allowance releases at certain of our 
Brazil and Vietnam subsidiaries.

The Company believes that it is more likely than not that the net deferred tax assets as shown below will be 

realized when future taxable income is generated through the reversal of existing taxable temporary differences and 
income that is expected to be generated by businesses that have long-term contracts or a history of generating 
taxable income. The Company continues to monitor the utilization of its deferred tax asset for its U.S. consolidated 
net operating loss carryforward. Although management believes it is more likely than not that this deferred tax asset 
will be realized through generation of sufficient taxable income or reversal of deferred tax liabilities prior to 
expiration of the loss carryforwards, such realization is not assured.

The following table summarizes deferred tax assets and liabilities, as of the periods indicated (in millions):

The Company considers undistributed earnings of certain foreign subsidiaries to be indefinitely reinvested 

outside of the U.S. and, accordingly, no U.S. deferred taxes have been recorded with respect to such earnings in 
accordance with the relevant accounting guidance for income taxes. Should the earnings be remitted as dividends, 
the Company may be subject to additional U.S. taxes, net of allowable foreign tax credits. As of December 31, 
2016, the cumulative amount of foreign un-remitted earnings upon which U.S. income taxes have not been provided 
is approximately $4 billion. It is not practicable to estimate the amount of any additional taxes which may be payable 
on the undistributed earnings. 

Income from operations in certain countries is subject to reduced tax rates as a result of satisfying specific 

commitments regarding employment and capital investment. The Company's income tax benefits related to the tax 
status of these operations are estimated to be $20 million, $21 million and $38 million for the years ended 
December 31, 2016, 2015 and 2014, respectively. The per share effect of these benefits after noncontrolling 
interests was $0.02, $0.02 and $0.04 for the years ended December 31, 2016, 2015 and 2014, respectively.

As of December 31, 2016, 2015 and 2014, the total amount of unrecognized tax benefits was $369 million, 
$373 million and $394 million, respectively. The total amount of unrecognized tax benefits that would benefit the 
effective tax rate as of December 31, 2016, 2015 and 2014 is $332 million, $343 million and $366 million, 
respectively, of which $24 million, $24 million and $24 million, respectively, would be in the form of tax attributes that 
would warrant a full valuation allowance.

The total amount of unrecognized tax benefits anticipated to result in a net decrease to unrecognized tax 
benefits within 12 months of December 31, 2016 is estimated to be up to $10 million, primarily relating to statute of 
limitation lapses and tax exam settlements.

The Company and certain of its subsidiaries are currently under examination by the relevant taxing authorities 
for various tax years. The Company regularly assesses the potential outcome of these examinations in each of the 
taxing jurisdictions when determining the adequacy of the amount of unrecognized tax benefit recorded. While it is 
often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, we 
believe we have appropriately accrued for our uncertain tax benefits. However, audit outcomes and the timing of 
audit settlements and future events that would impact our previously recorded unrecognized tax benefits and the 
range of anticipated increases or decreases in unrecognized tax benefits are subject to significant uncertainty. It is 
possible that the ultimate outcome of current or future examinations may exceed our provision for current 
unrecognized tax benefits in amounts that could be material, but cannot be estimated as of December 31, 2016. 
Our effective tax rate and net income in any given future period could therefore be materially impacted.

22. DISCONTINUED OPERATIONS

Brazil Distribution — Due to a portfolio evaluation in the first half of 2016, management has decided to pursue 
a strategic shift of its distribution companies in Brazil, AES Sul and Eletropaulo. The disposal of Sul was completed 
in October 2016. In December 2016, Eletropaulo underwent a corporate restructuring which is expected to, among 
other things, provide more liquidity of its shares. AES is continuing to pursue strategic options for Eletropaulo in 
order to complete its strategic shift to reduce AES’ exposure to the Brazilian distribution business, including 
preparation for listing its shares into the Novo Mercado, which is a listing segment of the Brazilian stock exchange 
with the highest standards of corporate governance.

The Company executed an agreement for the sale of its wholly-owned subsidiary AES Sul in June 2016. We 

have reported the results of operations and financial position of AES Sul as discontinued operations in the 
consolidated financial statements for all periods presented. Upon meeting the held-for-sale criteria, the Company 
recognized an after tax loss of $382 million comprised of a pretax impairment charge of $783 million, offset by a tax 
benefit of $266 million related to the impairment of the Sul long lived assets and a tax benefit of $135 million for 
deferred taxes related to the investment in AES Sul. Prior to the impairment charge in the second quarter, the 
carrying value of the AES Sul asset group of $1.6 billion was greater than its approximate fair value less costs to 
sell. However, the impairment charge was limited to the carrying value of the long lived assets of the AES Sul 
disposal group. 

On October 31, 2016, the Company completed the sale of AES Sul and received final proceeds less costs to 
sell of $484 million, excluding contingent consideration. Upon disposal of AES Sul, we incurred an additional after-
tax loss on sale of $737 million. The cumulative impact to earnings of the impairment and loss on sale was $1.1 
billion. This includes the reclassification of approximately $1 billion of cumulative translation losses, resulting in a 
net reduction to the Company’s stockholders’ equity of $92 million. 

 Sul’s pretax loss attributable to AES for the years ended December 31, 2016 and 2015 was $1.4 billion and 

$32 million, respectively. Sul’s pretax gain attributable to AES for the year ended December 31, 2014 was $133 
million. Prior to its classification as discontinued operations, Sul was reported in the Brazil SBU reportable segment.

As discussed in Note 1—General and Summary of Significant Accounting Policies, effective July 1, 2014, the 
Company prospectively adopted ASU No. 2014-08. Discontinued operations prior to adoption of ASU No. 2014-08 
include the results of Cameroon, Saurashtra and various U.S. wind projects which were each sold in the first half of 
2014.

Cameroon — In September 2013, the Company executed agreements for the sale of its 56% equity interests 

in businesses in Cameroon: Sonel, an integrated utility, Kribi, a gas and light fuel oil plant, and Dibamba, a heavy 

179

fuel oil plant. The sale was completed in June 2014. Net proceeds from the sale transaction were $200 million, of 
which $156 million was received in 2014. Of the remaining non-contingent consideration of $44 million, $40 million 
was received in the second quarter of 2016. Between meeting the held-for-sale criteria in September 2013 and 
completing the sale in June 2014, the Company recognized impairments of $101 million and an additional loss on 
sale of $7 million. Prior to classification as discontinued operations, these businesses were reported in the Europe 
SBU reportable segment.

Saurashtra — In October 2013, the Company executed an agreement for the sale of Saurashtra, a wind 
project in India. The sale transaction was completed in February 2014 and net proceeds of $8 million were received. 
Prior to its classification as discontinued operations, Saurashtra was reported in the Asia SBU reportable segment.

U.S. Wind Projects — In November 2013, the Company executed an agreement for the sale of its 100% 
membership interests in three wind projects: Condon in California, Lake Benton I in Minnesota and Storm Lake II in 
Iowa. Upon meeting the held-for-sale criteria for these three projects, the Company recognized impairment expense 
of $47 million (of which $7 million was attributable to noncontrolling interests held by tax equity partners) 
representing the difference between their aggregate carrying amount of $77 million and the fair value less costs to 
sell of $30 million. The sale was completed in January 2014 and net proceeds of $27 million were received. Prior to 
classification as discontinued operations, these businesses were reported in the US SBU reportable segment.

As the sale of AES Sul closed October 31, 2016, there were no assets or liabilities of discontinued operations 

and held-for-sale businesses at December 31, 2016. The following table summarizes the carrying amounts of the 
major classes of assets and liabilities of discontinued operations and held-for-sale businesses at December 31,

23. DISPOSITIONS

U.K. Wind — During the second quarter of 2016, the Company deconsolidated UK Wind and recorded a loss 

on deconsolidation of $20 million to Gain on disposal and sale of businesses in the Consolidated Statement of 
Operations. Prior to deconsolidation, UK Wind was reported in the Europe SBU reportable segment. See Note 15—
Equity for additional information.

DPLER — In December 2015, the Company executed an agreement for the sale of its ownership interest in 

DPLER, a competitive retail marketer selling electricity to customers in Ohio. Accordingly, DPLER was classified as 
held-for-sale as of December 31, 2015, but did not meet the criteria to be reported as a discontinued operation. 
DPLER's results were therefore reflected within continuing operations in the Consolidated Statements of 
Operations.

On January 1, 2016, the Company completed the sale of its interest in DPLER and recognized a gain on sale 

of $49 million. Proceeds of $76 million were received on December 31, 2015. The proceeds were classified as 
restricted cash with a corresponding amount recorded in Accrued and other liabilities in the Consolidated Balance 
Sheet as of December 31, 2015. DPLER's pretax income attributable to AES for the year ended December 31, 2015 
was $11 million and pretax loss attributable to AES for the year ended December 31, 2014 was $129 million. Prior to 
its sale, DPLER was reported in the US SBU reportable segment. 

Kelanitissa — In August 2015, the Company executed an agreement for the sale of its 90% ownership interest 
in Kelanitissa, a diesel-fired generation plant in Sri Lanka. Accordingly, Kelanitissa was classified as held-for-sale as 
of December 31, 2015, but did not meet the criteria to be reported as a discontinued operation. Kelanitissa's results 
were therefore reflected within continuing operations in the Consolidated Statements of Operations.

On January 27, 2016, the Company completed the sale of its interest in Kelanitissa. Upon completion, 
proceeds of $18 million were received and a loss on sale of $5 million was recognized. Kelanitissa's pretax loss 
attributable to AES for the year ended December 31, 2015 was $7 million and pretax income attributable to AES for 
the year ended December 31, 2014 was $1 million. Prior to its sale, Kelanitissa was reported in the Asia SBU 
reportable segment. 

Armenia Mountain — Under the terms of the sale agreement for certain U.S. Wind Projects, the buyer was 
provided an option to purchase the Company's 100% interest in Armenia Mountain, a wind project in Pennsylvania, 
at a fixed price of $75 million. The buyer exercised the option on March 31, 2015 and completed the sale of its 
interest in Armenia Mountain on July 1, 2015. The sale did not meet the criteria to be reported as a discontinued 
operation. Upon completion, net proceeds of $64 million were received and a pretax gain on sale of $22 million was 
recognized. Excluding the gain on sale, Armenia Mountain's pretax income attributable to AES was $6 million and 
$7 million for the years ended December 31, 2015 and 2014, respectively. Prior to its sale, Armenia Mountain was 
reported in the US SBU reportable segment. 

Ebute — On November 20, 2014, the Company completed the sale of its interest in Ebute, which included its 

95% interest in AES Nigeria Barge Limited and its 100% interest in AES Nigeria Barge Operations Limited. 
Proceeds from the sale were $22 million and the Company recognized a loss on sale of $6 million. As Ebute did not 
meet the criteria to be reported as a discontinued operation, its results were reflected within continuing operations in 
the Consolidated Statements of Operations. Excluding the loss on sale, Ebute's pretax loss attributable to AES was 
$27 million for the year ended December 31, 2014. Prior to its sale, Ebute was reported in the Europe SBU 
reportable segment. 

U.K. Wind (Operating Projects) — On August 22, 2014, the Company completed the sale of its interests in four 

operating wind projects located in the U.K.. Total net proceeds from the sale were $158 million and the Company 
recognized a pretax gain on sale of $78 million. As these wind projects did not meet the criteria to be reported as 
discontinued operations, their results were reflected within continuing operations in the Consolidated Statements of 
Operations. Excluding the gain on sale, the pretax loss attributable to AES for these disposed projects was $18

million for the year ended December 31, 2014. Prior to the sale, U.K. Wind (Operating Projects) were reported in 
the Europe SBU reportable segment.

24. ACQUISITIONS

Distributed Energy — On February 18, 2015, the Company completed the acquisition of 100% of the common 

stock of Main Street Power Company, Inc. for approximately $25 million. The purchase consideration was 
composed of $20 million cash and the fair value of earn-out payments of $5 million. At December 31, 2015, the 
assets acquired (including $4 million cash) and liabilities assumed at the acquisition date were recorded at fair 
value based on the final purchase price allocation, which resulted in the recognition of $16 million of goodwill. After 
the date of acquisition, Main Street Power Company, Inc. was renamed Distributed Energy, Inc.

On September 16, 2016, Distributed Energy acquired the equity interest of various projects held by multiple 

partnerships for approximately $43 million. These partnerships were previously classified as equity method 
investments. In accordance with the accounting guidance for business combinations, the Company has recorded 
the opening balance sheets of the acquired businesses based on the purchase price allocation as of the acquisition 
date.

25. EARNINGS PER SHARE

Basic and diluted earnings per share are based on the weighted-average number of shares of common stock 

and potential common stock outstanding during the period. Potential common stock, for purposes of determining 
diluted earnings per share, includes the effects of dilutive restricted stock units, stock options and convertible 
securities. The effect of such potential common stock is computed using the treasury stock method or the if-
converted method, as applicable.

The following table is a reconciliation of the numerator and denominator of the basic and diluted earnings per 
share computation for income from continuing operations for the years ended December 31, 2016, 2015 and 2014, 
where income represents the numerator and weighted-average shares represent the denominator. Values are in 
millions except per share data:

Income from continuing operations, net of tax, of $8 million less the $5 million adjustment to retained earnings to record the DP&L redeemable preferred stock 
at its redemption value as of December 31, 2016.

The calculation of diluted earnings per share excluded 8 million, 8 million and 6 million stock awards 

outstanding for the years ended December 31, 2016, 2015 and 2014, respectively, that could potentially dilute basic 
earnings per share in the future. Additionally, for the years ended December 31, 2016, 2015 and 2014, all 15 million 
convertible debentures were omitted from the earnings per share calculation. The stock awards and convertible 
debentures were excluded from the calculation because they were anti-dilutive. 

26. RISKS AND UNCERTAINTIES 

AES is a diversified power generation and utility company organized into six market-oriented SBUs. See 
additional discussion of the Company's principal markets in Note 16—Segment and Geographic Information. Within 
our six SBUs, we have two primary lines of business: Generation and Utilities. The Generation line of business uses 
a wide range of fuels and technologies to generate electricity such as coal, gas, hydro, wind, solar and biomass. 
Our Utilities business is comprised of businesses that transmit, distribute, and in certain circumstances, generate 
power. In addition, the Company has operations in the renewables area. These efforts include projects primarily in 
wind and solar.

Operating and Economic Risks — The Company operates in several developing economies where 
macroeconomic conditions are usually more volatile than developed economies. Deteriorating market conditions 
often expose the Company to the risk of decreased earnings and cash flows due to, among other factors, adverse 

182

THE AES CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2016, 2015, AND 2014

fluctuations in the commodities and foreign currency spot markets. Additionally, credit markets around the globe 
continue to tighten their standards, which could impact our ability to finance growth projects through access to 
capital markets. Currently, the Company has a below-investment grade rating from Standard & Poor's of BB-. This 
could affect the Company's ability to finance new and/or existing development projects at competitive interest rates. 
As of December 31, 2016, the Company had $1.3 billion of unrestricted cash and cash equivalents.

During 2016, 74% of our revenue was generated outside the U.S. and a significant portion of our international 

operations is conducted in developing countries. We continue to invest in several developing countries to expand 
our existing platform and operations. International operations, particularly the operation, financing and development 
of projects in developing countries, entail significant risks and uncertainties, including, without limitation:

•  economic, social and political instability in any particular country or region;
• 

inability to economically hedge energy prices;

•  volatility in commodity prices;
•  adverse changes in currency exchange rates;

•  government restrictions on converting currencies or repatriating funds;
•  unexpected changes in foreign laws, regulatory framework, or in trade, monetary or fiscal policies;
•  high inflation and monetary fluctuations;
• 
• 
•  unwillingness of governments, government agencies, similar organizations or other counterparties to honor 

restrictions on imports of coal, oil, gas or other raw materials required by our generation businesses to operate;
threatened or consummated expropriation or nationalization of our assets by foreign governments;

their commitments;

•  unwillingness of governments, government agencies, courts or similar bodies to enforce contracts that are 

economically advantageous to subsidiaries of the Company and economically unfavorable to counterparties, 
against such counterparties, whether such counterparties are governments or private parties;
inability to obtain access to fair and equitable political, regulatory, administrative and legal systems;

• 
•  adverse changes in government tax policy;
•  difficulties in enforcing our contractual rights, enforcing judgments, or obtaining a just result in local 

jurisdictions; and

•  potentially adverse tax consequences of operating in multiple jurisdictions.

Any of these factors, individually or in combination with others, could materially and adversely affect our 
business, results of operations and financial condition. In addition, our Latin American operations experience 
volatility in revenue and earnings which have caused and are expected to cause significant volatility in our results of 
operations and cash flows. The volatility is caused by regulatory and economic difficulties, political instability, 
indexation of certain PPAs to fuel prices, and currency fluctuations being experienced in many of these countries. 
This volatility reduces the predictability and enhances the uncertainty associated with cash flows from these 
businesses.

Our inability to predict, influence or respond appropriately to changes in law or regulatory schemes, including 
any inability to obtain reasonable increases in tariffs or tariff adjustments for increased expenses, could adversely 
impact our results of operations or our ability to meet publicly announced projections or analysts' expectations. 
Furthermore, changes in laws or regulations or changes in the application or interpretation of regulatory provisions 
in jurisdictions where we operate, particularly our Utility businesses where electricity tariffs are subject to regulatory 
review or approval, could adversely affect our business, including, but not limited to:

•  changes in the determination, definition or classification of costs to be included as reimbursable or pass-

through costs;

•  changes in the definition or determination of controllable or noncontrollable costs;

•  adverse changes in tax law;

•  changes in the definition of events which may or may not qualify as changes in economic equilibrium;

•  changes in the timing of tariff increases;

•  other changes in the regulatory determinations under the relevant concessions; or

183

THE AES CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2016, 2015, AND 2014

•  changes in environmental regulations, including regulations relating to GHG emissions in any of our 

businesses.

Any of the above events may result in lower margins for the affected businesses, which can adversely affect 

our results of operations.

Construction — As of December 31, 2016, the Company has 531 MW under construction at Alto Maipo. 

Increased project costs, or delays in construction, could have an adverse impact on the Company. 

Foreign Currency Risks — AES operates businesses in many foreign countries and such operations could 
be impacted by significant fluctuations in foreign currency exchange rates. Fluctuations in currency exchange rate 
between U.S. Dollar and the following currencies could create significant fluctuations to earnings and cash flows: 
the Argentine peso, the Brazilian real, the Dominican Republic peso, the Euro, the Chilean peso, the Colombian 
peso, the Philippine peso and the Kazakhstan tenge.

Concentrations — Due to the geographical diversity of its operations, the Company does not have any 
significant concentration of customers or sources of fuel supply. Several of the Company's generation businesses 
rely on PPAs with one or a limited number of customers for the majority of, and in some cases all of, the relevant 
businesses' output over the term of the PPAs. However, no single customer accounted for 10% or more of total 
revenue in 2016, 2015 or 2014.

The cash flows and results of operations of our businesses depend on the credit quality of our customers and 

the continued ability of our customers and suppliers to meet their obligations under PPAs and fuel supply 
agreements. If a substantial portion of the Company's long-term PPAs and/or fuel supply were modified or 
terminated, the Company would be adversely affected to the extent that it would be unable to replace such 
contracts at equally favorable terms.

27. RELATED PARTY TRANSACTIONS

Certain of our businesses in Panama and the Dominican Republic are partially owned by governments either 
directly or through state-owned institutions. In the ordinary course of business, these businesses enter into energy 
purchase and sale transactions, and transmission agreements with other state-owned institutions which are 
controlled by such governments. At two of our generation businesses in Mexico, the offtakers exercise significant 
influence, but not control, through representation on these businesses' Boards of Directors. These offtakers are also 
required to hold a nominal ownership interest in such businesses. In Chile, we provide capacity and energy under 
contractual arrangements to our investment which is accounted for under the equity method of accounting. 
Additionally, the Company provides certain support and management services to several of its affiliates under 
various agreements.

ITEM 9A. CONTROLS AND PROCEDURES

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures that are designed to ensure that information 
required to be disclosed in the reports that the Company files or submits under the Securities Exchange Act of 
1934, as amended (the "Exchange Act") is recorded, processed, summarized and reported within the time periods 
specified in the SEC's rules and forms, and that such information is accumulated and communicated to the CEO 
and CFO, as appropriate, to allow timely decisions regarding required disclosures.

The Company carried out the evaluation required by Rules 13a-15(b) and 15d-15(b), under the supervision 
and with the participation of our management, including the CEO and CFO, of the effectiveness of our “disclosure 
controls and procedures” (as defined in the Exchange Act Rules 13a-15(e) and 15d-15(e)). Based upon this 
evaluation, the CEO and CFO concluded that as of December 31, 2016, our disclosure controls and procedures 
were effective.

Management's Report on Internal Control over Financial Reporting

Management of the Company is responsible for establishing and maintaining adequate internal control over 

financial reporting, as defined in Rule 13a-15(f) under the Exchange Act. The Company's internal control over 
financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial 
reporting and the preparation of financial statements for external purposes in accordance with GAAP and includes 
those policies and procedures that:
• 

pertain to the maintenance of records that in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the Company;
provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial 
statements in accordance with GAAP, and that receipts and expenditures of the Company are being made only 
in accordance with authorizations of management and directors of the Company; and
provide reasonable assurance that unauthorized acquisition, use or disposition of the Company's assets that 
could have a material effect on the financial statements are prevented or detected timely.

• 

• 

Management, including our CEO and CFO, does not expect that our internal controls will prevent or detect all 
errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not 
absolute, assurance that the objectives of the control system are met. Further, the design of a control system must 
reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their 
costs. In addition, any evaluation of the effectiveness of controls is subject to risks that those internal controls may 
become inadequate in future periods because of changes in business conditions, or that the degree of compliance 
with the policies or procedures deteriorates.

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 

2016. In making this assessment, management used the criteria established in Internal Control—Integrated 
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") in 2013. 
Based on this assessment, management believes that the Company maintained effective internal control over 
financial reporting as of December 31, 2016.

The effectiveness of the Company's internal control over financial reporting as of December 31, 2016, has 
been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report, 
which appears herein.

Changes in Internal Control Over Financial Reporting:

There were no changes that occurred during the quarter ended December 31, 2016 that have materially 

affected, or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of The AES Corporation:

We have audited The AES Corporation’s internal control over financial reporting as of December 31, 2016, 
based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (2013 Framework) (the COSO criteria). The AES Corporation’s 
management is responsible for maintaining effective internal control over financial reporting, and for its assessment 
of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report 
on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company’s internal 
control over financial reporting based on our audit.

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

A company’s internal control over financial reporting is a process designed to provide reasonable assurance 

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

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

In our opinion, The AES Corporation maintained, in all material respects, effective internal control over 

financial reporting as of December 31, 2016, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States), the consolidated balance sheets of The AES Corporation as of December 31, 2016 and 2015, and 
the related consolidated statements of operations, comprehensive income, changes in equity, and cash flows for 
each of the three years in the period ended December 31, 2016 of The AES Corporation and our report dated 
February 24, 2017 expressed an unqualified opinion thereon.

NOTES TO SCHEDULE I

1. Application of Significant Accounting Principles

The Schedule I Condensed Financial Information of the Parent includes the accounts of The AES Corporation 

(the “Parent Company”) and certain holding companies.

Accounting for Subsidiaries and Affiliates—The Parent Company has accounted for the earnings of its 

subsidiaries on the equity method in the financial information.

Income Taxes—Positions taken on the Parent Company's income tax return which satisfy a more-likely-than-

not threshold will be recognized in the financial statements. The income tax expense or benefit computed for the 
Parent Company reflects the tax assets and liabilities on a stand-alone basis and the effect of filing a consolidated 
U.S. income tax return with certain other affiliated companies.

Accounts and Notes Receivable from Subsidiaries—Amounts have been shown in current or long-term 

assets based on terms in agreements with subsidiaries, but payment is dependent upon meeting conditions 
precedent in the subsidiary loan agreements.
