Chairman’s Letter

It certainly was a tough year economically for our  
region. We expect that the challenges our service area 
experienced in 2009, will continue in 2010. 

DPL Matches Challenges with Toughness

When things are tough, performance becomes even more 
important in the vital areas we measure:

• Safety

• Service

• Reliability

• Operating Performance 

As Paul Barbas discusses in his report, we tracked very 
well in all these performance measures in 2009.  
From the Board of Directors’ viewpoint, we are very proud 
of the way our employees have responded to the  
challenges we have faced. As a football coach of mine 
many years ago was fond of saying, “when the going gets 
tough, the tough get going.” Well, DPL’s employees  
fulfilled this old adage to the highest degree during 2009. 

DPL Innovates

There is another important benchmark that applies in  
tough times, and that is the ability to innovate.  
You may find it surprising to think of an electric utility  
as a source of innovation. Conventional wisdom has it that 
small entrepreneurs are the only source of innovation.  
But we think otherwise.

Following Paul Barbas’ leadership, DPL has innovated  
in a number of areas:

Innovative partnerships, like the new relationship 
with the Wright-Patterson Air Force Base to privatize its 
electrical distribution and transmission system.

Innovative environmental performance, like the industry-
leading installation of scrubbers that remove sulfur dioxide 
and our selective catalytic reduction equipment that 
reduces nitrogen oxide emissions from our coal-fired plants. 
Over the years, the company has invested millions to help 
protect the environment and comply with regulations. 

In 2009, we started converting some turf areas on our 
property to prairie meadows. These natural landscapes 
reduce noise and emissions by eliminating mowing.  
It also provides an aesthetic, natural buffer between our 
equipment and adjacent properties. And in the northeastern 
part of our service area, we’re actually restoring what had 
been prairie prior to the settlement of Ohio.

Glenn E. Harder

building late in the year that will  
be a first step toward a more 
diversified energy portfolio. 

Innovation is something DPL 
believes in and embraces 
every day. After all, the Dayton 
area has been known for its 
innovative spirit for over a century. 

Would you expect anything less from its electric utility?

DPL Performance Gets Noticed in 2009

At DPL, we are dedicated to meeting the highest standards 
of corporate governance and operational excellence. In 
April 2009, DPL was named one of the 100 Most Trustworthy 
Companies by Forbes Magazine. The list highlights those 
companies that “have consistently shown transparent and 
conservative accounting practices and solid corporate  
governance and management.” We are extremely proud 
of this recognition as it underscores our ongoing efforts to 
ensure that DPL is a fundamentally sound company  
worthy of your investment consideration.

Additionally, with our improved risk profile, Standard & 
Poor’s, Moody’s Investors Service and Fitch Ratings  
all upgraded the credit ratings of both DPL and DP&L. 

The bottom line is that our strengthened operations,  
improved cash flows, and consistent earnings growth  
translated into additional value for our shareholders.  
In December 2009, we increased our dividend rate by  
six percent, our fifth consecutive annual increase.  
Coupled with a substantial increase in stock price, our  
total return to shareholders for the year was impressive 
under any circumstances.

Toughness and Determination will Continue in 2010

Congratulations to the DPL team for outstanding  
performance during 2009. The future will demand nothing 
less than continuing excellence, because the electric utility 
industry, this country and our customers face continued 
challenges and opportunities. 

Your Board is confident that challenging times will do 
nothing less than call out the determination and toughness 
of our employees to meet those challenges. Thank you 
for your confidence in DPL. The DPL Board of Directors 
sincerely appreciates your continued support.

Innovative technology, like our future vision for a smarter 
electrical grid that provides customers with a greater  
degree of reliability and choice, and therefore customer 
service. And the 1.1 MW solar power facility we began

President & CEO’s Letter

In 2009, we were challenged once again with deep  

recessionary economic conditions regionally and 

nationally. In spite of the downturn, DPL maintained its 

focus on operational excellence, cost control,  

our regulatory negotiations and on identifying new  

ways to grow our business.

economic engine for the Dayton region and Ohio,  

and we’re pleased to support the base and its mission. 

Additionally, DP&L played an important role in  

the successful region-wide effort to attract Caterpillar’s 

second-largest distribution center to Clayton, Ohio, 

which is in the northern part of our service territory. 

We also introduced several energy efficiency initiatives  

to help our residential and commercial customers better 

manage their energy expenses. Under these programs, 

DPL creates a more stable  
environment for the company and  
for our customers as an active  
participant in strengthening the  
economy in the Miami Valley.

over 2008. This is a testament to the professionalism 

and dedication of our more than 1,500 employees.

These efforts also improve the day-to-day reliability  

of our system, which better prepares us to handle  

future weather events. 

Our focus on execution has translated into a stronger 

financial position as we look to 2010. We re-purchased 

$227 million of long term debt, driven by our positive 

cash flows. Additionally, we reduced the number of

outstanding common stock warrants from 19.6 million  

to 1.8 million. As a result of our operational, regulatory 

and financial efforts, all three rating agencies upgraded 

the credit ratings of both DPL and DP&L during 2009. 

My leadership team recognizes  
that it is the people who work for  
DPL that make all of our  
accomplishments possible.

Strong Teamwork and Communication

FERC cyber-security requirements and a host of other 

demands that have been placed upon our industry  

over the last two to three years, it is imperative that 

we continue to invest heavily in our workforce.  

Although simple in concept, I truly believe that we  

can grow as a company only if employees throughout 

our business continue to expand their knowledge  

and capabilities. I am pleased to say that the Board, 

leadership team and all of our employees enjoy  

the challenges of being part of this learning culture.

I am looking forward to the challenges and  

opportunities 2010 will present to DPL.  

We are committed to maintaining a sharp focus  

on operational excellence, strong financial  

performance and a solid reputation among our  

investors, customers, regulators and the communities 

we serve. DPL is well positioned to succeed  

today and into the future and we thank you for  

your investment in our company.

Paul M. Barbas

President & Chief Executive Officer

March 1, 2010

One of the company’s strengths is the ability to work 

together to accomplish goals – no matter how small or 

large – necessary to ensure DPL’s success. 

A collaborative effort on the part of our commercial 

operations, generation and maintenance and material 

handling areas allowed us to complete a transition to 

burning lower cost coal at our Killen and Stuart plants. 

Providing safe and reliable  
electric service to our customers  
is always at the core of our business. 

The flue gas desulfurization units – which remove  

nearly all of the sulfur dioxide from our plant emissions – 

combined with the ingenuity of our workforce made  

this possible. Due to our prudent investments in  

environmental technology, we have greater flexibility  

in the types of coal we can burn, which ultimately  

results in lower fuel costs for our customers.

We are also making strides in adding renewable  

energy sources to our fuel mix and have begun the  

testing of both biofuels and engineered fuels at  

our power generation stations. Additionally, we have 

commenced the construction of the largest solar  

array in southwestern Ohio and continue to explore  

additional opportunities with a variety of partners  

as we work to meet the requirements of Ohio’s  

legislation on alternative energy. 

Investing in Our Employees and the Future

Since 2007, we have more than doubled the investment 

we make in our employees through additional  

training. As we look at meeting renewable energy  

targets, expanding our efficiency programs, upgrading 

our substations and distribution facilities, meeting

Cost-Competitive Generation Continued

Fuel Flexibility Reduces Costs

The successful operation of the selective catalytic 

reduction equipment and flue gas desulfurization units 
(scrubbers) at our Killen and Stuart power plants  
allows DPL to have more flexibility in the coal we burn. 
And the greater flexibility we have in our choice of  

coal, the lower fuel costs we can realize. In 2009,  
DPL used a blend of Central Appalachian coal and 
higher-sulfur Illinois Basin coal, which is less  
expensive for the company to buy.

Exploring Alternative Energy Sources

DPL has been conducting research and development 
activities in renewable energy. Specifically, we’ve  
explored biofuel testing and in December began the 
installation of a solar array in our service territory. 

The first biofuel tested was a pellet composed of  
scrap wood and switch grass. We blended the pellets 
with coal and conducted EPA-approved test burns  
in the Killen boiler.

The solar array converts solar energy from the sun  
into electrical current, and DPL’s array will have  
the ability to power nearly 150 homes. A visitor center  
to educate the public about solar power is also  
planned as part of the installation.

Reliably Serving  
Over 500,000 Customers
 Customer service, safety, and reliability – these are the three

primary concerns of DPL’s service operations. In 2009, 
DPL made several changes to improve performance in each  
of these areas.

Stepping Up Service

To better serve our customers every day, we increased the  

telecommunications capacity in our Customer Solutions 
Call Center. This allows us to receive and answer more calls, 
and more quickly respond to our customers’ needs.  
In addition, we’ve begun to take customer inquiries via e-mail, 
so customers can get answers even when it’s not  
convenient for them to call.

DPL also enhanced its communication with groups that can 
help our employees and our customers during storm recovery. 
We reached out to county administrators and emergency  
management agencies and initiated processes to better  
coordinate our restoration efforts with theirs – such as assistance 
in clearing roadways to provide linemen access to our  
facilities – during adverse weather conditions.

Ensuring Safety and Reliability

Another addition to our contingency planning is our new 
membership in the Southeast Electric Exchange (SEE), a 
mutual aid cooperative that coordinates the flow of resources, 
people, and equipment to member utilities in times of need.

Customer service, safety, and reliability –  
these are the three primary concerns of  
DPL’s service operations.

As a long-time member of a similar organization – the Great 
Lakes Mutual Assistance Group – we have helped utilities in 
other states when they have faced natural disasters, and we 
have benefited from their reciprocal efforts. In early 2009, for 
example, we sent DP&L workers to Kentucky to help restore 
power after an ice storm there. By joining the SEE, we increase 
the number of resources we can call upon when we need them.

Updated personal protective equipment and enhanced 
training on best practices in the field has enabled  
DP&L employees to work more safely. As a result, lost-time  
accidents have decreased from 8 in 2008 to only 1 in 2009.

Helping Our Customers Conserve

Working to meet the requirements of Ohio energy legislation, 
DPL implemented a series of energy efficiency programs  
designed to help our residential and business customers 
reduce their electricity usage and save money. These  
initiatives – such as compact fluorescent lightbulb (CFL)  
discounts, refrigerator recycling and business rebates –  
have been very well received by customers. In fact, more  
than one million DP&L-discounted CFLs were sold in 2009!

7

Our Community

 Now more than ever, the strength 

of a business relies on the strength of  
its customers and communities.  
In addition to economic development  
initiatives, DPL also continued its  
tradition of helping the individuals and 
organizations in our service territory  
and the areas surrounding our  
generation facilities.

In 2009, DPL employees participated  
in many projects that directly  
affected our neighbors. For example, 
the company sponsored three  
houses that were rehabbed as a part  
of the Rebuilding Together Dayton  
initiative, and provided about 20 
employee volunteers who worked on 
National Rebuilding Day.

DPL and the DP&L Foundation 
continue to provide vital  
support to the communities  
we serve.

Employees at the power plants along 
the Ohio River coordinated multiple 
drives to collect clothing, gifts, and 
funds for numerous local charities, 
including Hospice of Hope, March of 
Dimes and St. Vincent De Paul.

ABC’s hit TV show “Extreme Makeover:  
Home Edition” filmed at a residence in 
our service territory this summer.  
More than 100 DPL employees signed 
up to volunteer to help with the  
custom renovation. Our company  
also assisted in making sure the work  
site had power for the multi-day,  
around-the-clock operation.

DPL and the DP&L Foundation continue 
to provide vital support to the  
communities we serve by contributing 
more than $1 million annually to  
a variety of civic, cultural, and youth  
organizations. 

A team of DPL employees rehabbed a Dayton  

home as part of National Rebuilding Day through  

Rebuilding Together Dayton.

Organization
DPL is a regional energy company organized in 1985 
under the laws of Ohio. Our executive offices are 
located at 1065 Woodman Drive, Dayton, Ohio 45432 – 
telephone (937) 224-6000.

DPL’s principal subsidiary is DP&L. DP&L is a 
public utility incorporated in 1911 under the laws of 
Ohio. DP&L sells electricity to residential, commercial, 
industrial and governmental customers in a 6,000 
square mile area of West Central Ohio. Electricity for 
DP&L’s 24 county service area is primarily generated 
at eight coal-fired power plants and is distributed to 
more than 500,000 retail customers. Principal industries 
served include automotive, food processing, paper, 
plastic, manufacturing and defense. DP&L’s sales 
reflect the general economic conditions and seasonal 
weather patterns of the area. DP&L sells any excess 
energy and capacity into the wholesale market. DP&L 
also sells electricity to DPLER, an affiliate, to satisfy the 
electric requirements of its retail customers.

DPL’s other significant subsidiaries (all of which 
are wholly-owned) include: DPLE, which engages in 
the operation of peaking generating facilities and  
sells power in wholesale markets; DPLER, which sells 
retail electric energy under contract to major industrial 
and commercial customers in West Central Ohio;  
and MVIC, which is our captive insurance company 
that provides insurance to us and our subsidiaries. 

DPL also has a wholly-owned business trust, DPL 
Capital Trust II, formed for the purpose of issuing trust 
capital securities to investors. 

DPL and DP&L conduct their principal business 
in one business segment – Electric. DP&L’s electric 
transmission and distribution businesses are subject to 
rate regulation by federal and state regulators while its 
generation business is not subject to such regulation. 
Accordingly, DP&L applies the accounting standards 
for regulated operations to its electric transmission and 
distribution businesses and records regulatory assets 
when incurred costs are expected to be recovered in 
future customer rates, and regulatory liabilities when 
current recoveries in customer rates relate to expected 
future costs.

DPL and its subsidiaries employed 1,581 persons 

as of January 31, 2010, of which 1,403 were full-time 
employees and 178 were part-time employees. At 
that date, 1,396 of these full-time employees and all 
of the part-time employees were employed by DP&L. 
Approximately 55% of the employees are under a  
collective bargaining agreement.

Long-Term Debt Redemption

On March 31, 2009, DPL paid $175 million of the 8.00% Senior Notes when the notes became due. In addition, 
on December 21, 2009, DPL paid down $52.4 million of the $195 million 8.125% Note to DPL Capital Trust II 
which is due 2031.

New Revolving Credit Facility

On April 21, 2009, DP&L entered into a $100 million unsecured revolving credit agreement with a syndicated 
bank group. The agreement is for a 364-day term expiring on April 20, 2010. The facility contains one financial  
covenant: DP&L’s total debt to total capitalization ratio is not to exceed 0.65 to 1.00. As of December 31, 2009, 
this covenant is met with a ratio of 0.40 to 1.00. As of December 31, 2009, there were no borrowings outstanding 
under this facility. 

Warrants Repurchased and Exercised

During the year ended December 31, 2009, DPL repurchased a total of 8.6 million of its warrants at an average 
price of $2.94 each. The repurchased warrants were cancelled by DPL on the dates they were repurchased. 
Also during this period, warrant holders exercised a total of 9.2 million warrants, of which 5.5 million were exercised 
under cashless transactions and 3.7 million were exercised for cash. As a result of these warrant exercise  
transactions, DPL issued a total of 5.0 million shares of common stock from treasury stock and in turn received 
total cash proceeds of $77.7 million.

Stock Repurchase Program

On October 28, 2009, the DPL Board of Directors approved a Stock Repurchase Program under which DPL may 
use proceeds from the exercise of warrants (discussed above) to repurchase common stock and warrants from 
time to time in the open market, through private transactions or otherwise. The Stock Repurchase Program  
will run through June 30, 2012, which is approximately three months after the end of the warrant exercise period. 
Through December 31, 2009, DPL repurchased approximately 2.4 million shares of common stock under the 
Stock Repurchase Program at an average price per share of $26.96.

Approval of Stipulation

In compliance with SB 221, DP&L filed its ESP at the PUCO on October 10, 2008. Subsequently on February 24, 
2009, DP&L filed the Stipulation signed by the Staff of the PUCO, the Office of the OCC and various intervening 
parties. On June 24, 2009, the PUCO issued an order granting approval of the Stipulation. 

Transmission, Ancillary and Other PJM-related Costs

On February 19, 2009, the PUCO approved DP&L’s request to defer costs related to transmission, capacity, 
ancillary service and other costs incurred since July 31, 2008 consistent with the provisions of SB 221. 
Subsequently, the PUCO approved two separate riders in November 2009, one for the recovery of RPM capacity 
costs and another rider for the recovery of transmission, ancillary and other PJM-related costs (TCRR). Accordingly, 
during the period ended December 31, 2009, DP&L deferred net RTO and other costs in the amount of $25.5
million. Of this amount, approximately $9.8 million relates to the period August 1, 2008 through December 31, 2008, 
and $15.7 million relates to the twelve month period ended December 31, 2009. The deferral of these costs  
resulted in a favorable impact to our results of operations.

(a) DP&L sells power to DPLER (a subsidiary of DPL). The revenues associated with these sales are classified as wholesale sales on 
DP&L’s financial statements and retail sales for DPL. The kWh volumes contain all volumes distributed on the DP&L system which include 
the retail sales by DPLER. The sales for resale volumes are omitted from DP&L to avoid duplicate reporting.

DPL’s present summer generating capacity, including peaking units, is approximately 3,794 MW. Of this 
capacity, approximately 2,827 MW, or 75%, is derived from coal-fired steam generating stations and the balance  
of approximately 967 MW, or 25%, consists of combustion turbine and diesel peaking units. 

DP&L’s present summer generating capacity, including peaking units, is approximately 3,249 MW. Of this 
capacity, approximately 2,827 MW, or 87%, is derived from coal-fired steam generating stations and the balance  
of approximately 422 MW, or 13%, consists of combustion turbine and diesel peaking units. 

Our all-time net peak load was 3,270 MW, occurring August 8, 2007. 
Approximately 87% of the existing steam generating capacity is provided by certain generating units owned  
as tenants in common with Duke Energy-Ohio (or its subsidiaries The Cincinnati Gas & Electric Company [CG&E],

or Union Heat, Light & Power) and AEP (or its subsidiary Columbus Southern Power [CSP]). As tenants in  
common, each company owns a specified share of each of these units, is entitled to its share of capacity and  
energy output, and has a capital and operating cost responsibility proportionate to its ownership share.  
DP&L’s remaining steam generating capacity (approximately 365 MW) is derived from a generating station 
owned solely by DP&L. Additionally, DP&L, CG&E and CSP own, as tenants in common, 884 circuit miles of 
345,000-volt transmission lines. DP&L has several interconnections with other companies for the purchase, 
sale and interchange of electricity.

In 2009, we generated 99.5% of our electric output from coal-fired units and 0.5% from oil and natural  

gas-fired units.

In addition to the above, DP&L also owns a 4.9% equity ownership interest in OVEC, an electric generating 
company. OVEC has two plants in Cheshire, Ohio and Madison, Indiana with a combined generation capacity of 
approximately 2,265 MW. DP&L’s share of this generation capacity is approximately 111 MW.

DPL has substantially all of the total expected coal volume needed to meet its retail and firm wholesale sales 

requirements for 2010 under contract. The majority of the contracted coal is purchased at fixed prices. Some  
contracts provide for periodic adjustments and some are priced based on market indices. Fuel costs are impacted 
by changes in volume and price and are driven by a number of variables including weather, the wholesale  
market price of power, certain provisions in coal contracts related to government imposed costs, counterparty  
performance and credit, scheduled outages and generation plant mix. Our emission allowance consumption  
was reduced in 2008 and 2009 due to the installation of FGD equipment (scrubbers) at our jointly-owned electric  
generating stations. Due to the installation of this emission control equipment and barring any changes in the  
regulatory environment in which we operate, we expect to have emission allowance inventory in excess of our 
needs, which we plan to sell during 2010 and in future periods. We were a net seller of SO2 allowances and 
NOx allowances in 2009, and we expect to be a net seller in 2010.

demand for electricity is generally greater in the sum-
mer months associated with cooling and in the winter 
months associated with heating as compared to other 
times of the year. Unusually mild summers and winters 
could have an adverse effect on our results of opera-
tions, financial condition and cash flows.

Rate Regulation and Government Legislation

DP&L’s sales to retail customers are subject to rate 
regulation by the PUCO. Beginning January 1, 2010, 
DP&L has a fuel rider in place for the collection of our 
prudently incurred fuel, purchased power, emission 
and other related costs. DP&L’s transtmission rates 
and wholesale electric rates to municipal corporations, 
rural electric co-operatives and other distributors of 
electric energy are subject to regulation by the FERC 
under the Federal Power Act.

Ohio law establishes the process for determining 

retail rates charged by public utilities. Regulation of 
retail rates encompasses the timing of applications, the 
effective date of rate increases, the recoverable costs 
basis upon which the rates are based and other related 
matters. Ohio law also established the Office of the 
OCC, which has the authority to represent residential 
consumers in state and federal judicial and administra-
tive rate proceedings.

Ohio legislation extends the jurisdiction of the 
PUCO to the records and accounts of certain public 
utility holding company systems, including DPL. The 
legislation extends the PUCO’s supervisory powers to a 
holding company system’s general condition and capi-
talization, among other matters, to the extent that such 
matters relate to the costs associated with the provision 
of public utility service. Based on existing PUCO and 
FERC authorization, regulatory assets and liabilities are 
recorded on the balance sheets. See Note 3 of Notes 
to Consolidated Financial Statements.

Since January 2001, DP&L’s electric customers have 
been permitted to choose their retail electric generation 
supplier. DP&L continues to have the exclusive right 
to provide delivery service in its state certified territory 
and the obligation to supply retail generation service  
to customers that do not choose an alternative supplier. 
The PUCO maintains jurisdiction over DP&L’s delivery 
of electricity, standard service offer and other retail 
electric services. 

On May 1, 2008, substitute SB 221, an Ohio elec-
tric energy bill, was signed by the Governor and went 
into effect July 31, 2008. This law required that all Ohio 
distribution utilities file either an electric security plan or 
a market rate option that was to be in effect on January 
1, 2009. Under the market rate option, a periodic  
competitive bid process will set the retail generation 
price after the utility demonstrates that it can meet cer-
tain market criteria and bid requirements set out in the  
bill. Also, under this option, utilities that still own gen-
eration in the state are required to phase in the market 
rate option over a period of not less than five years. 
An electric security plan may allow for adjustments to 
the standard service offer for costs associated with 
environmental compliance; fuel and purchased power; 
construction of new or investment in specified generat-
ing facilities; and the provision of standby and default 
service, operating, maintenance, or other costs includ-
ing taxes. As part of its electric security plan, a utility  
is permitted to file an infrastructure improvement plan 
that will specify the initiatives the utility will take to 
rebuild, upgrade, or replace its electric distribution 
system, including cost recovery mechanisms. Both the 
market rate option and electric security plan option 
involve a “substantially excessive earnings” test based 
on the earnings of comparable companies with similar 
business and financial risks. The PUCO issued three 
sets of rules related to implementation of the law. These 
rules address topics such as the information that must 
be included in an electric security plan as well as a 
market rate option, the significantly excessive earnings 
test requirements, corporate separation revisions, rules 
relating to the recovery of transmission related costs, 
electric service and safety standards dealing with the 
statewide line extension policy, and rules relating to 
advanced energy portfolio standards, renewable ener-
gy, demand reduction and energy efficiency standards.

In compliance with SB 221, DP&L filed its ESP at 

the PUCO on October 10, 2008. This plan contained 
three parts: 1) a standard offer plan; 2) a CCEM plan; 
and 3) an alternative energy plan. The standard offer 
plan stated that DP&L intends to maintain its current 
rate plan through December 31, 2010, and addressed 
compliance issues related to the PUCO rules.

SB 221 and the implementation rules contain tar-
gets relating to advanced energy portfolio standards, 
renewable energy, demand reduction and energy 
efficiency standards. After several revisions, rulings 
on rehearing and reissuance that occurred throughout 
2009, the rules relating to renewable energy, energy 
efficiency, demand reduction and integrated resource 
plans were made effective on December 10, 2009. The 
standards require that, by the year 2025, 25% of the 
total number of kWh of electricity sold by the utility to 
retail electric consumers must come from alternative 
energy resources, which include “advanced energy 
resources” such as distributed generation, clean coal, 
advanced nuclear, energy efficiency and fuel cell tech-
nology; and “renewable energy resources” such as 
solar, hydro, wind, geothermal and biomass. At least 
half of the 25% must be generated from renewable 
energy resources, including 0.5% from solar energy. 
The renewable energy portfolio, energy efficiency 
and demand reduction standards began in 2009 with 
increases in required percentages each year. The 
annual targets for energy efficiency are expected to 
save 22.3% by 2025 and peak demand reductions 
are expected to reach 7.75% by 2018 compared to 
baseline energy usage. If any targets are not met, 
compliance penalties will apply unless the PUCO 
makes certain findings that would excuse performance. 
In December 2009, DP&L and DPLER made several 
filings relating to their renewable energy and energy 
efficiency compliance plans. DP&L and DPLER were 
able to obtain Renewable Energy Certificates suf-
ficient to meet their overall renewable energy targets, 
but DP&L and DPLER together obtained only 36% of 
the separate requirement for 2009 Ohio-based solar 
power. The companies asked for a waiver of any unmet 
2009 Ohio solar requirements on grounds of force 
majeure because there are insufficient solar renewable 
energy credits available from Ohio resources. In two 
separate filings, DP&L requested the PUCO’s consent 
that DP&L had met the requirements for energy effi-
ciency and for demand reduction based on DP&L’s 
interpretation of how those requirements should be 
applied. These filings also requested that if the PUCO 
disagreed with DP&L’s interpretation, the PUCO grant 

alternative relief and find that DP&L was unable to 
meet the targets due to reasons beyond its reason-
able control, i.e. uncertainty throughout 2009 caused 
by delays in finalizing the rules and the lack of timely 
PUCO action on several of DP&L’s special contracts 
relating to demand response efforts which remain 
pending before the PUCO. In addition, the rules that 
became effective December 10, 2009 required that 
on January 1, 2010, DP&L file an extensive energy 
efficiency portfolio plan, outlining how DP&L plans to 
comply with the energy efficiency and demand reduc-
tion benchmarks. DP&L filed a separate request for a 
finding that it had already complied with this require-
ment in the form of DP&L’s portfolio plan that had been 
filed in 2008 as part of its electric security plan, which 
had been approved by the PUCO and is being imple-
mented. We are unable to predict at this time how the 
PUCO will respond to these filings, but believe that the 
outcome will not be material to our financial condition. 
However, as the targets get increasingly larger over 
time, the costs of complying with the SB 221 targets 
and the PUCO’s implementing rules could have a 
material impact on our financial condition. 

On February 24, 2009, DP&L filed the Stipulation 

with the PUCO which was signed by the Staff of  
the PUCO, the Office of the OCC and various interven-
ing parties. The material terms agreed to under the 
Stipulation include the following:

n DP&L’s current rate plan will be extended 
through 2012.

n DP&L will be permitted to implement a fuel and 
purchased power recovery mechanism beginning 
January 1, 2010 which will track and adjust fuel and 
purchased power costs on a quarterly basis. 

n The rate stabilization surcharge remains a non-
bypassable provider of last resort charge at its current 
rate amount, but may be bypassable by customers 
served by a government aggregator beginning 2011.  
If a government aggregator elects to avoid this  
surcharge in 2011 and 2012, its customers can only 
return to DP&L at a market-based rate.

n The last phase of the EIR increase will occur in 
2010 as previously approved by the PUCO and there-
after will remain at that level through 2012.

n DP&L’s base distribution and generation rates will 
be frozen through 2012. 

n DP&L may seek recovery of certain cost increases 
such as storm damage expenses, regulatory or tax 

12  DPL Inc.

changes, costs associated with new climate change  
or carbon regulations, certain costs associated with the 
operation of the Hutchings station, costs associated 
with TCRR and Regional Transmission Organization 
costs not covered by the TCRR. 

n The significantly excessive earnings test will not 
apply to DP&L until 2012. 

n DP&L will be permitted to begin its energy efficiency 
and demand response programs immediately with 
recovery scheduled to begin in 2009, with a two-year 
reconciliation. DP&L’s smart grid deployment initia-
tive will be revised and resubmitted to the PUCO for 
approval by September 2009 with the anticipation that 
the plans and recovery will begin January 1, 2010 also 
with a two year reconciliation.

n DP&L’s proposed alternative energy plans will be 
approved and recovery of these costs will begin in 
2009 with an annual reconciliation. 

n Mercantile (large use) customers can obtain exemp-
tion from the energy efficiency rider if self-directed 
energy and demand programs generate reductions 
equal to or greater than DP&L’s energy and demand 
reduction benchmarks. 

On June 24, 2009, the PUCO issued an order grant-
ing approval of the Stipulation as filed and authorized 
DP&L to implement rates associated with alternative 
energy and energy efficiency compliance costs, which 
DP&L implemented beginning on July 1, 2009. 

Consistent with the Stipulation, DP&L filed its 
smart grid and advanced metering infrastructure busi-
ness cases with the PUCO on August 4, 2009 seeking 
recovery of costs associated with a three-year plan to 
deploy smart meter; and a ten-year plan for distribu-
tion and substation automation, core telecommunica-
tions, supporting software and in-home technologies. 
On August 5, 2009, DP&L submitted an application 
for American Recovery and Reinvestment Act (ARRA) 
funding under the Integrated and/or Crosscutting 
Systems topic area for the Smart Grid Investment Grant 
Program, seeking $145.1 million of matching funds. 
On October 27, 2009, we were notified by the United 
States Department of Energy (DOE) that we will not 
receive funding under the ARRA. A technical confer-
ence was held at the PUCO in October 2009 for  
the smart grid case, and a subsequent PUCO entry 
established a comment and reply comment period.  
The PUCO Staff along with other interested parties 
provided comments and reply comments on DP&L’s 
plans. A hearing is not yet scheduled for this case. 

The Stipulation provided for the establishment of 
a fuel and purchased power recovery rider beginning 
January 1, 2010. DP&L filed its proposed fuel rider on 
October 30, 2009. On December 16, 2009 the PUCO 
issued an order stating the rate was consistent with 
the Stipulation provisions, that it does not appear to 
be unjust or unreasonable, and approved the rate to 
be implemented on January 1, 2010. The fuel rider will 
fluctuate based on actual costs and recoveries and 
will be modified at the start of each seasonal quarter: 
March 1, June 1, September 1, and December 1 each 
year. Consistent with the Stipulation, an annual review 
and audit is scheduled to take place in the first quarter 
of 2011 for calendar year 2010. 

As a member of PJM, DP&L incurs costs and 
receives revenues from the RTO related to its transmis-
sion and generation assets, as well as its load obliga-
tions for retail customers. SB 221 included a provision 
that allows Ohio electric utilities to seek and obtain a 
reconcilable rider to recover RTO-related costs and 
credits. In early 2009, the PUCO approved DP&L’s 
request to defer costs associated with its transmis-
sion, capacity, ancillary service and other PJM-related 
charges incurred as a member of PJM consistent with 
the provisions of SB 221. DP&L subsequently filed to 
establish the TCRR that would incorporate all charges 
and credits from the RTO as well as the amounts 
approved for deferral. The TCRR was approved by the 
PUCO and on June 1, 2009 DP&L began recovery of 
these costs. In June 2009, an application for rehearing 
was filed claiming the PUCO’s order allowing for recov-
ery of RPM costs through this rider was unlawful. On 
September 9, the PUCO granted rehearing, and issued 
an entry ordering DP&L to remove the RPM costs from 
the TCRR and refile its tariffs. On September 23, 2009, 
the Company filed two separate riders, a TCRR without 
RPM costs, and an RPM recovery rider, which were 
both subsequently approved per PUCO Finding and 
Order issued on November 18, 2009, and implemented 
December 1, 2009. There was no change to the level  
of recovery due to the rehearing process.

On September 9, 2009, the PUCO issued an entry 

establishing a significantly excessive earnings test 
(SEET) proceeding. A workshop was held at the PUCO 
offices on October 5, 2009 to allow interested parties 
to present concerns and discuss issues related to the 
methodology for determining whether an electric util-
ity has significantly excessive earnings pursuant to 
the provisions contained in SB 221. On November 18, 
2009, the PUCO Staff issued its recommendations to 
the PUCO. DP&L filed its comments and reply com-

DPL Inc.

ments along with other interested parties. Although 
DP&L’s Stipulation provides that the SEET does not 
apply to it until 2013 based on 2012 earnings results, 
DP&L is actively participating in this proceeding.

On August 28, 2009, DP&L filed its application 
to establish reliability targets consistent with the most 
recent PUCO Electric Service and Safety Standards 
(ESSS). The PUCO issued a procedural schedule and 
held a technical conference on November 10, 2009. 
Comments and reply comments were filed. We expect 
this case will be set for hearing. According to the  
ESSS rules, DP&L will be subject to financial penalties 
if the established targets are not met for two consecu-
tive years.

While the overall financial impact of SB 221 will  
not be known for some time, implementation of the  
bill and compliance with its requirements could have  
a material impact on our financial condition. 

Ohio Competitive Considerations and Proceedings

As of December 31, 2009, six unaffiliated marketers 
were registered as CRES providers in DP&L’s service 
territory. While there has been some customer switch-
ing associated with unaffiliated marketers, it repre-
sented less than 0.11% of sales in 2009. DPLER, an 
affiliated company, is also a registered CRES provider 
and accounted for 99% of the total kWh supplied by 
CRES providers within DP&L’s service territory in 2009. 
During the first quarter of 2010, DPLER will begin pro-
viding CRES services to business customers who are 
currently not in DP&L’s service territory. At this time, we 
do not expect these incremental costs and revenues 
to have a material impact on our results of operations, 
financial position or cash flows. In 2003-2004, several 
communities in DP&L’s service area passed ordinanc-
es allowing the communities to become government 
aggregators for the purpose of offering alternative  
electric generation supplies to their citizens. To date, 
none of these communities have aggregated their  
generation load. 

Federal Matters
Like other electric utilities and energy marketers, DP&L 
and DPLE may sell or purchase electric products 
on the wholesale market. DP&L and DPLE compete 
with other generators, power marketers, privately and 
municipally-owned electric utilities and rural electric 
cooperatives when selling electricity. The ability of 
DP&L and DPLE to sell this electricity will depend on 
how DP&L’s and DPLE’s price, terms and conditions 
compare to those of other suppliers. 

As part of Ohio’s electric deregulation law, all of 
the state’s investor-owned utilities are required to join a 

RTO. In October 2004, DP&L successfully integrated 
its 1,000 miles of high-voltage transmission into the 
PJM RTO. The role of the RTO is to administer a com-
petitive wholesale market for electricity and ensure 
reliability of the transmission grid. PJM ensures the 
reliability of the high-voltage electric power system 
serving 51 million people in all or parts of Delaware, 
Illinois, Indiana, Kentucky, Maryland, Michigan, New 
Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, 
Virginia, West Virginia and the District of Columbia. 
PJM coordinates and directs the operation of the 
region’s transmission grid, administers the world’s larg-
est competitive wholesale electricity market and plans 
regional transmission expansion improvements to main-
tain grid reliability and relieve congestion.

The PJM RPM base residual auction for the 
2012/13 period cleared at a per megawatt price of 
$16/day for our RTO area. Prior to this auction, the per 
megawatt price for the 2011/2012 period was $110/
day. Future RPM auction results will be dependent not 
only on the overall supply and demand of generation 
and load, but may also be impacted by congestion 
as well as PJM’s business rules relating to bidding for 
Demand Response and Energy Efficiency resources in 
the RPM auctions. We cannot predict the outcome of 
future auctions but if the current auction price is sus-
tained, our future results of operations, financial condi-
tion and cash flows could be adversely impacted.
As a member of PJM, DP&L is also subject to 
charges and costs associated with PJM operations as 
approved by the FERC. FERC Orders issued in 2007 
regarding the allocation of costs of large transmission 
facilities within PJM, could result in additional costs 
being allocated to DP&L of approximately $12 mil-
lion or more annually by 2012. DP&L filed a notice of 
appeal to the U.S. Court of Appeals, D.C. Circuit on 
March 18, 2008 challenging the allocation method. 
The appeal was consolidated with other appeals taken 
by other interested parties of the same FERC Orders 
and the consolidated cases were assigned to the 7th 
Circuit. On August 6, 2009, the 7th Circuit ruled that the 
FERC had failed to provide a reasoned basis for the 
allocation method it had approved. Rehearings were 
filed by other interested litigants and denied by the 
Court, which then remanded the matter to the FERC  
for further proceedings. On January 21, 2010, the 
FERC issued a procedural order on remand estab-
lishing a paper hearing process under which PJM 
will make an informational filing in late February. 
Subsequently PJM and other parties, including DP&L, 
will be able to file initial comments, testimony, and 
recommendations and reply comments. Absent future 

14  DPL Inc.

changes to the procedural schedule that may occur 
for a number of reasons including if settlement discus-
sions are held, the paper hearing process should be 
complete and the case ready for FERC consideration 
in 2010. FERC did not establish a deadline for its issu-
ance of a substantive order. DP&L cannot predict the 
timing or the likely outcome of the proceeding. Until 
such time as FERC may act to approve a change in 
methodology, PJM will continue to apply the alloca-
tion methodology that had been approved by FERC 
in 2007. Although we continue to maintain that these 
costs should be borne by the beneficiaries of these 
projects and that DP&L is not one of these beneficia-
ries, any new credits or additional costs resulting from 
the ultimate outcome of this proceeding will be reflect-
ed in DP&L’s TCRR rider which is already in place to 
pass through RTO-related costs and credits.

DP&L provides transmission and wholesale elec-
tric service to twelve municipal customers in its service 
territory, which in turn distribute electricity principally 
within their incorporated limits. DP&L also maintains 
an interconnection agreement with one municipality 
that has the capability to generate a portion of its  
own energy requirements. Approximately one percent 
of total electricity sales in 2009 represented sales to 
these municipalities.

In June 2009, the NERC, a FERC-certified electric 
reliability organization responsible for developing and 
enforcing mandatory reliability standards, commenced 
a routine audit of DP&L’s operations. The audit, which 
was for the period June 18, 2007 to June 25, 2009, 
evaluated DP&L’s compliance with 42 requirements 
in 18 NERC-reliability standards. DP&L is currently 
subject to a compliance audit at a minimum of once 
every three years as provided by the NERC Rules of 
Procedure. This audit was concluded in June 2009 and 
its findings revealed that DP&L had some Possible 
Alleged Violations (PAVs) associated with five NERC 
Reliability Standards. In response to the report, DP&L 
filed mitigation plans with NERC to address the PAVs. 
These mitigation plans have been accepted and DP&L 
is currently awaiting a proposal for settlement from 
NERC. While we are currently unable to determine the 
extent of penalties, if any, that may be imposed on 
DP&L, we do not believe such penalties will have a 
material impact on our results of operations.

Environmental Considerations

DPL and DP&L’s facilities and operations are subject 
to a wide range of environmental regulations and laws 
by federal, state and local authorities. The environmen-
tal issues that may impact us include:

n The Federal CAA and state laws and regulations 
(including State Implementation Plans) which require 
compliance, obtaining permits and reporting as to  
air emissions.

n Litigation with federal and certain state governments 
and certain special interest groups regarding whether 
modifications to or maintenance of certain coal-fired 
generating plants require additional permitting or  
pollution control technology, or whether emissions from 
coal-fired generating plants cause or contribute to 
global climate changes.

n Rules issued by the USEPA and Ohio EPA that 
require substantial reductions in SO2, particulates, 
mercury and NOx emissions. DPL has installed emis-
sion control technology and is taking other measures  
to comply with required and anticipated reductions.

n Rules issued by the USEPA and Ohio EPA that 
require reporting and future reductions of GHGs.

n Rules issued by the USEPA associated with the 
Federal Clean Water Act (FCWA), which prohibits the 
discharge of pollutants into waters of the United  
States except pursuant to appropriate permits. 

n Solid and hazardous waste laws and regulations, 
which govern the management and disposal of certain 
waste. The majority of solid waste created from the 
combustion of coal and fossil fuels is fly ash and other 
coal combustion by-products. The EPA has previously 
determined that fly ash and other coal combustion 
by-products are not hazardous waste subject to the 
Resource Conservation and Recovery Act (RCRA), but 
the EPA is reportedly reconsidering that determination. 
A change in determination could significantly increase 
the costs of disposing of such by-products.

As well as imposing continuing compliance obligations, 
these laws and regulations authorize the imposition 
of substantial penalties for noncompliance, includ-
ing fines, injunctive relief and other sanctions. In the 
normal course of business, we have investigatory and 
remedial activities underway at these facilities to com-
ply, or to determine compliance, with such regulations. 
We record liabilities for probable estimated loss in 
accordance with the provisions of GAAP relating to the 
accounting for contingencies. DPL, through its wholly-
owned captive insurance subsidiary MVIC, has an 
actuarially calculated reserve of $1.2 million for envi-
ronmental matters. We evaluate the potential liability 
related to probable losses quarterly and may revise our 
estimates. Such revisions in the estimates of the poten-
tial liabilities could have a material effect on our results 
of operations, financial position or cash flows.

Environmental Regulation and Litigation  
Related to Air Quality 

Air Quality

In 1990, the federal government amended the CAA to 
further regulate air pollution. Under the law, the USEPA 
sets limits on how much of a pollutant can be in the air 
anywhere in the United States. The CAA allows individ-
ual states to have stronger pollution controls, but states 
are not allowed to have weaker pollution controls than 
those set for the whole country. The CAA has a material 
effect on our operations and such effects are detailed 
below with respect to certain programs under the CAA. 
On October 27, 2003, the USEPA published final 
rules regarding the equipment replacement provision 
(ERP) of the routine maintenance, repair and replace-
ment (RMRR) exclusion of the CAA. Activities at power 
plants that fall within the scope of the RMRR exclu-
sion do not trigger new source review requirements, 
including the imposition of stricter emission limits. 
On December 24, 2003, the United States Court of 
Appeals for the D.C. Circuit stayed the effective date 
of the rule pending its decision on the merits of the 
lawsuits filed by numerous states and environmental 
organizations challenging the final rules. On June 
6, 2005, the USEPA issued its final response on the 
reconsideration of the ERP exclusion. The USEPA clari-
fied its position, but did not change any aspect of the 
2003 final rules. This decision was appealed and the 
D.C. Circuit vacated the final rules on March 17, 2006. 
The scope of the RMRR exclusion remains uncertain 
due to this action by the D.C. Circuit, as well as mul-
tiple litigations not directly involving us where courts 
are defining the scope of the exception with respect to 
the specific facts and circumstances of the particular 
power plants and activities before the courts. While we 
believe that we have not engaged in any activities with 
respect to our existing power plants that would trig-
ger the new source review requirements, if new source 
review requirements were imposed on any of DP&L’s 
existing power plants, the results could be materially 
adverse to us.

The USEPA issued a proposed rule on October 20, 
2005 concerning the test for measuring whether modifi-
cations to electric generating units should trigger  
application of New Source Review (NSR) standards 
under the CAA. A supplemental rule was also pro-
posed on May 8, 2007 to include additional options for 
determining if there is an emissions increase when an 
existing electric generating unit makes a physical or 
operational change. The rule was challenged by envi-
ronmental organizations and has not been finalized. 

While we cannot at this time predict the outcome of  
this rulemaking, any finalized rules could materially 
affect our operations.

On December 17, 2003, the USEPA proposed 
the Interstate Air Quality Rule (IAQR) designed to 
reduce and permanently cap SO2 and NOx emissions 
from electric utilities. The proposed IAQR focused on 
states, including Ohio, whose power plant emissions 
are believed to be significantly contributing to fine 
particle and ozone pollution in other downwind states 
in the eastern United States. On June 10, 2004, the 
USEPA issued a supplemental proposal to the IAQR, 
now renamed the CAIR. The final rules were signed on 
March 10, 2005 and were published on May 12, 2005. 
CAIR created an interstate trading program for annual 
NOx emission allowances and made modifications to 
an existing trading program for SO2. On August 24, 
2005, the USEPA proposed additional revisions to the 
CAIR. On July 11, 2008, the U.S. Court of Appeals for 
the District of Columbia Circuit issued a decision to 
vacate the USEPA’s CAIR and its associated Federal 
Implementation Plan and remanded to the USEPA with 
instructions to issue new regulations that conformed 
to the procedural and substantive requirements of 
the CAA. The Court’s decision, in part, invalidated the 
new NOx annual emission allowance trading program 
and the modifications to the SO2 emission trading 
program established by the March 10, 2005 rules, 
and created uncertainty regarding future NOx and 
SO2 emission reduction requirements and their timing. 
The USEPA and a group representing utilities filed a 
request on September 24, 2008 for a rehearing before 
the entire Court. On December 23, 2008, the U.S. 
Court of Appeals issued an order on reconsideration 
that permits CAIR to remain in effect until the USEPA 
issues new regulations that would conform to the CAA 
requirements and the Court’s July 11, 2008 decision. 
In January 2010, the Court ordered the USEPA to file a 
response to request for a USEPA decision filed by par-
ties in the original case who are now seeking a Court 
order to require the USEPA to issue new regulations by 
March 1, 2010. We are currently unable to predict the 
outcome of this request or the timing or impact of any 
new regulations relating to CAIR. CAIR has and will 
continue to have a material effect on our operations.

In 2007, the Ohio EPA revised their State 

Implementation Plan (SIP) to incorporate a CAIR pro-
gram consistent with the IAQR. The Ohio EPA had 
received partial approval from the USEPA and had 
been awaiting full program approval from the USEPA 
when the U.S. Court of Appeals issued its July 11,  
2008 decision. As a result of the December 23, 2008 

16  DPL Inc.

order, the Ohio EPA proposed revised rules on May 
11, 2009, which were finalized on July 15, 2009. On 
September 25, 2009, the USEPA issued a full SIP 
approval for the Ohio CAIR program. We do not expect 
that full SIP approval of the Ohio CAIR program will 
have a significant impact on operations.

In the fourth quarter of 2007, DP&L began a pro-
gram for selling excess emission allowances, including 
annual NOx emission allowances and SO2 emission 
allowances that were the subject of CAIR trading pro-
grams. In subsequent quarters, DP&L recognized 
gains from the sale of excess emission allowances to 
third parties. The court’s CAIR decision affected the 
trading market for excess allowances and impacted 
DP&L’s program for selling additional excess allow-
ances in 2008. Although in January 2009 we resumed 
selling excess allowances due to the revival of the trad-
ing market, the long-term impact of the court’s deci-
sion and of the actions the USEPA or others will take in 
response to this decision, is not fully known at this time 
and could have an adverse effect on us. 

On January 30, 2004, the USEPA published its  

proposal to restrict mercury and other air toxins  
from coal-fired and oil-fired utility plants. The USEPA  
“de-listed” mercury as a hazardous air pollutant from 
coal-fired and oil-fired utility plants and, instead, 
proposed a cap-and-trade approach to regulate the 
total amount of mercury emissions allowed from such 
sources. The final Clean Air Mercury Rule (CAMR) was 
signed March 15, 2005 and was published on May 18, 
2005. On March 29, 2005, nine states sued the USEPA, 
opposing the cap-and-trade regulatory approach 
taken by the USEPA. In 2007, the Ohio EPA adopted 
rules implementing the CAMR program. On February 
8, 2008, the U.S. Court of Appeals for the District of 
Columbia Circuit struck down the USEPA regulations, 
finding that the USEPA had not complied with statutory 
requirements applicable to “de-listing” a hazardous 
air pollutant and that a cap-and-trade approach was 
not authorized by law for “listed” hazardous air pollut-
ants. A request for rehearing before the entire Court of 
Appeals was denied and a petition for review before 
the U.S. Supreme Court was filed on October 17, 2008. 
On February 23, 2009, the U.S. Supreme Court denied 
the petition. The USEPA is expected to move forward 
on setting Maximum Available Control Technology 
(MACT) standards for coal- and oil-fired electric gen-
erating units. Upon publication in the federal register 
following finalization, affected electric generating units 
(EGUs) will have three years to come into compli-
ance with the new requirements. At this time, DP&L is 
unable to determine the impact of the promulgation of 

new MACT standards on its financial position or results 
of operations; however, a MACT standard could have a 
material adverse effect on our operations, in particular, 
our unscrubbed units. We cannot at this time project 
the final costs we may incur to comply with any result-
ing mercury restriction regulations.

On January 5, 2005, the USEPA published its final 

non-attainment designations for the National Ambient 
Air Quality Standard (NAAQS) for Fine Particulate 
Matter 2.5 (PM 2.5). These designations included 
counties and partial counties in which DP&L oper-
ates or owns generating facilities. On March 4, 2005, 
DP&L and other Ohio electric utilities and electric 
generators filed a petition for review in the D.C. Circuit 
Court of Appeals, challenging the final rule creat-
ing these designations. On November 30, 2005, the 
court ordered the USEPA to decide on all petitions for 
reconsideration by January 20, 2006. On January 20, 
2006, the USEPA denied the petitions for reconsidera-
tion. On July 7, 2009, the D.C. Circuit Court of Appeals 
upheld the USEPA non-attainment designations for the 
areas impacting DP&L’s generation plants, however, 
on October 8, 2009, the USEPA issued new designa-
tions based on 2008 monitoring data that showed all 
areas in attainment to the standard with the exception 
of several counties in northeastern Ohio. The USEPA is 
expected to propose revisions to the PM 2.5 standard 
in late 2010 as part of its routine five-year rule review 
cycle. At this time, DP&L is unable to determine the 
impact the revisions to the PM 2.5 standard will have 
on its financial position or results of operations.

On May 5, 2004, the USEPA issued its proposed 
regional haze rule, which addresses how states should 
determine the Best Available Retrofit Technology 
(BART) for sources covered under the regional haze 
rule. Final rules were published July 6, 2005, provid-
ing states with several options for determining whether 
sources in the state should be subject to BART. In the 
final rule, the USEPA made the determination that CAIR 
achieves greater progress than BART and may be 
used by states as a BART substitute. Numerous units 
owned and operated by us will be impacted by BART. 
We cannot determine the extent of the impact until 
Ohio determines how BART will be implemented. 

In response to a U.S. Supreme Court decision that 

the USEPA has the authority to regulate CO2 emis-
sions from motor vehicles, the USEPA made a finding 
that CO2 and certain other gases are pollutants under 
the CAA. The USEPA has not yet identified the specif-
ics of how these newly designated pollutants will be 
regulated. In April 2009, the USEPA issued a proposed 
endangerment finding under the CAA. The proposed 

DPL Inc. 

17

 
finding determined that CO2 and other GHGs from 
motor vehicles threaten the health and welfare of 
future generations by contributing to climate change. 
If the proposed finding is finalized, it could lead to the 
regulation of CO2 and other GHGs from sources other 
than motor vehicles, including coal-fired plants that 
we own and operate. Recently, several bills have been 
introduced at the federal level to regulate GHG emis-
sions. In June 2009, the U.S. House of Representatives 
passed H.R. 2454, the American Clean Energy and 
Security Act (ACES). This proposed legislation tar-
gets a reduction in the emission of GHGs from large 
sources by 80% in 2050 through an economy-wide cap 
and trade program. ACES also includes energy effi-
ciency and renewable energy initiatives. Approximately 
99% of the energy we produce is generated by coal. 
DP&L’s share of CO2 emissions at generating stations 
we own and co-own is approximately 16 million tons 
annually. Proposed GHG legislation finalized at a future 
date could have a significant effect on DP&L’s opera-
tions and costs, which could adversely affect our net 
income, cash flows and financial position. However, 
due to the uncertainty associated with such legislation, 
we are currently unable to predict the final outcome or 
the financial impact that this legislation will have on us. 
On September 22, 2009, the USEPA issued a final rule 
for mandatory reporting of GHGs from large sources 
that emit 25,000 metric tons per year or more of CO2, 
including electric generating units. The first report is 
due in March 2011 for 2010 emissions. This reporting 
rule will guide development of policies and programs 
to reduce emissions. DP&L does not anticipate that 
this reporting rule will result in any significant cost or 
other impact on current operations. 

On July 15, 2009, the USEPA proposed revisions 
to its primary NAAQS for nitrogen dioxide. This change 
could affect certain emission sources in heavy traffic 
areas like the I-75 corridor between Cincinnati and 
Dayton. At this point, DP&L cannot determine the 
effect of this potential change, if any, on its operations.
The USEPA proposed revisions to its primary 
NAAQS for SO2 on November 16, 2009. This would 
replace the current 24-hour standard and current annu-
al standard. This regulation is expected to be finalized 
in 2010. At this time, DP&L cannot determine the effect 
of this potential change, if any, on its operations. 

On September 16, 2009, the USEPA announced 
that it would reconsider the 2008 national ground level 
ozone standard. A more stringent ambient ozone stan-
dard may lead to stricter NOx emission standards in 
the future. At this point, DP&L cannot determine the 
effect of this potential change, if any, on its operations.

Air Quality – Litigation Involving Co-Owned Plants
In March 2000, as amended in June 2004, the U.S. 
Department of Justice filed a complaint in the United 
States District Court, Southern District of Indiana, 
Indianapolis Division against Cinergy Corp. (now part 
of Duke Energy) and two Cinergy subsidiaries for 
alleged violations of the CAA at various generation 
units operated by PSI Energy, Inc. and CG&E, includ-
ing generation units co-owned by DP&L (Beckjord Unit 
6 and Miami Fort Unit 7). A retrial has been held in 
which the second jury found for Duke Energy on some 
allegations, but for plaintiffs with respect to units at 
another one of Duke Energy’s wholly-owned facilities. In 
a separate phase II remedies trial with respect to viola-
tions found in the first trial, Duke Energy was ordered 
to close down three of its wholly-owned generating 
units by September 2009, surrender some emission 
allowances and pay a fine. None of the violations found 
or remedies ordered relate to generating units owned 
in part by DP&L. 

In 2004, eight states and the City of New York 
filed a lawsuit in Federal District Court for the Southern 
District of New York against American Electric 
Power Company, Inc. (AEP), one of AEP’s subsid-
iaries, Cinergy Corp. (a subsidiary of Duke Energy 
Corporation (Duke Energy)) and four other electric 
power companies. A similar lawsuit was filed against 
these companies in the same court by Open Space 
Institute, Inc., Open Space Conservancy, Inc. and The 
Audubon Society of New Hampshire. The lawsuits 
allege that the companies’ emissions of CO2 contribute 
to global warming and constitute a public or private 
nuisance. The lawsuits seek injunctive relief in the 
form of specific emission reduction commitments. In 
2005, the Federal District Court dismissed the lawsuits, 
holding that the lawsuits raised political questions that 
should not be decided by the courts. The plaintiffs 
appealed. Finding that the plaintiffs have standing 
to sue and can assert federal common law nuisance 
claims, the United States Court of Appeals for the 
Second Circuit on September 21, 2009 vacated  
the dismissal of the Federal District Court and remand-
ed the lawsuits back to the Federal District Court for 
further proceedings. Although we are not named  
as a party to these lawsuits, DP&L is a co-owner of 
coal-fired plants with Duke Energy and AEP (or their 
subsidiaries) that could be affected by the outcome 
of these lawsuits. The Second Circuit Court’s decision 
could also encourage these or other plaintiffs to file 
similar lawsuits against other electric power compa-
nies, including us. We are unable at this time to predict 
with certainty the impact that these lawsuits might  
have on us.

On September 21, 2004, the Sierra Club filed a 

lawsuit against DP&L and the other owners of the 
Stuart generating station in the U.S. District Court for 
the Southern District of Ohio for alleged violations of 
the CAA and the station’s operating permit. On August 
7, 2008, a consent decree was filed in the U.S. District 
Court in full settlement of these CAA claims. Under 
the terms of the consent decree, DP&L and the other 
owners of the Stuart generating station agreed to: (i) 
certain emission targets related to NOx, SO2 and par-
ticulate matter; (ii) make energy efficiency and renew-
able energy commitments that are conditioned on 
receiving PUCO approval for the recovery of costs; (iii) 
forfeit 5,500 SO2 allowances; and (iv) provide funding 
to a third party non-profit organization to establish a 
solar water heater rebate program. DP&L and the other 
owners of the station also entered into an attorneys’ fee 
agreement to pay a portion of the Sierra Club’s attor-
ney and expert witness fees. The parties to the lawsuit 
filed a joint motion on October 22, 2008, seeking an 
order by the U.S. District Court approving the consent 
decree with funding for the third party non-profit orga-
nization set at $300,000. On October 23, 2008, the 
U.S. District Court approved the consent decree. On 
October 21, 2009, the Sierra Club filed with the U.S. 
District Court a motion for enforcement of the consent 
decree based on the Sierra Club’s interpretation of the 
consent decree that would require certain NOx emis-
sions that DP&L has been excluding from its computa-
tions to be included for purposes of complying with 
the emission targets and reporting requirements of the 
consent decree. DP&L believes that it is properly com-
puting and reporting NOx emissions under the consent 
decree and has opposed the Sierra Club’s motion. A 
decision on the motion is expected before the end of 
the first quarter 2010. Because Stuart Station’s NOx 
emissions are well below the 2009 and 2010 limits in 
the consent decree under either method of calculation, 
an adverse decision would have no effect in 2010 on 
operations or costs. An adverse decision could affect 
compliance costs in future years when the NOx limits 
are further reduced under the consent decree.

Air Quality – Notices of Violation Involving  
Co-Owned Plants

On March 13, 2008, Duke Energy Ohio Inc., the opera-
tor of the Zimmer generating station, received a NOV 
and a Finding of Violation from the USEPA alleging 
violations of the CAA, the Ohio State Implementation 
Program (SIP) and permits for the Station in areas 
including SO2, opacity and increased heat input. DP&L 
is a co-owner of the Zimmer generating station and 

could be affected by the eventual resolution of  
this matter. Duke Energy Ohio Inc. is expected to act 
on behalf of itself and the co-owners with respect to 
this matter. At this time, DP&L is unable to predict the 
outcome of this matter.

In June 2000, the USEPA issued a NOV to the 
DP&L-operated Stuart generating station (co-owned 
by DP&L, CG&E and CSP) for alleged violations of the 
CAA. The NOV contained allegations consistent with 
NOVs and complaints that the USEPA had recently 
brought against numerous other coal-fired utilities in 
the Midwest. The NOV indicated the USEPA may: (1) 
issue an order requiring compliance with the require-
ments of the Ohio SIP; or (2) bring a civil action seek-
ing injunctive relief and civil penalties of up to $27,500 
per day for each violation. To date, neither action  
has been taken. At this time, DP&L cannot predict the 
outcome of this matter.

In November 1999, the USEPA filed civil com-

plaints and NOVs against operators and owners of 
certain generation facilities for alleged violations of the 
CAA. Generation units operated by CG&E (Beckjord 
Unit 6) and CSP (Conesville Unit 4) and co-owned by 
DP&L were referenced in these actions. Numerous 
northeast states have filed complaints or have indicat-
ed that they will be joining the USEPA’s action against 
CG&E and CSP. Although DP&L was not identified in 
the NOVs, civil complaints or state actions, the results 
of such proceedings could materially affect DP&L’s 
co-owned plants.

In December 2007, the Ohio EPA issued a NOV 
to the DP&L-operated Killen generating station (co-
owned by DP&L and CG&E) for alleged violations of 
the CAA. The NOVs alleged deficiencies in the continu-
ous monitoring of opacity. We submitted a compliance 
plan to the Ohio EPA on December 19, 2007. To date, 
no further actions have been taken by the Ohio EPA. 

Air Quality – Other Issues Involving Co-Owned Plants

In 2006, DP&L detected a malfunction with its emission 
monitoring system at the DP&L-operated Killen gen-
erating station (co-owned by DP&L and CG&E) and 
ultimately determined its SO2 and NOx emissions data 
was under reported. DP&L has petitioned the USEPA 
to accept an alternative methodology for calculating 
actual emissions for 2005 and the first quarter 2006. 
DP&L has sufficient allowances in its general account 
to cover the understatement and is working with the 
USEPA to resolve the matter. Management does not 
believe the ultimate resolution of this matter will have a 
material impact on results of operations, financial  
position or cash flows.

Air Quality – Notices of Violation Involving  
Wholly-Owned Plants

In 2007, the Ohio EPA and the USEPA issued NOVs 
to DP&L for alleged violations of the CAA at the O.H. 
Hutchings Station. The NOVs alleged deficiencies 
relate to stack opacity and particulate emissions. 
Discussions are under way with the USEPA, the U.S. 
Department of Justice and Ohio EPA. DP&L has pro-
vided data to those agencies regarding its mainte-
nance expenses and operating results. On December 
15, 2008, DP&L received a request from the USEPA for 
additional documentation with respect to those issues 
and other CAA issues including issues relating to capi-
tal expenses and any changes in capacity or output of 
the units at the O.H. Hutchings station. During 2009, 
DP&L has continued to submit various other operation-
al and performance data to the USEPA in compliance 
with its request. DP&L is currently unable to determine 
the timing, costs, or method by which the issues may 
be resolved and continues to work with the USEPA  
on this issue. 

On November 18, 2009, the USEPA issued a NOV 

to DP&L for alleged New Source Review (NSR) viola-
tions of the CAA at the O.H. Hutchings Station relating 
to capital projects performed in 2001 involving Unit 3 
and Unit 6. DP&L does not believe that the two proj-
ects described in the NOV were modifications subject 
to NSR. DP&L is unable to determine the timing, costs 
or method by which these issues may be resolved and 
continues to work with the USEPA on this issue.

Water Quality 

On July 9, 2004, the USEPA issued final rules pursu-
ant to the Clean Water Act governing existing facilities 
that have cooling water intake structures. The rules 
require an assessment of impingement or entrainment 
of organisms as a result of cooling water withdrawal. 
A number of parties appealed the rules to the Federal 
Court of Appeals for the Second Circuit in New York 
and the Court issued an opinion on January 25, 2007 
remanding several aspects of the rule to the USEPA 
for reconsideration. Several parties petitioned the U.S. 
Supreme Court for review of the lower court decision. 
On April 14, 2008, the Supreme Court elected to review 
the lower court decision on the issue of whether the 
USEPA can compare costs with benefits in determining 
the best technology available for minimizing adverse 
environmental impact at cooling water intake struc-
tures. Briefs were submitted to the Court in the summer 
of 2008 and oral arguments were held in December 
2008. In April 2009, the U.S. Supreme Court ruled that 
the USEPA did have the authority to compare costs 

with benefits in determining best technology available. 
The USEPA is developing proposed regulations which 
it hopes to issue for public comment by mid-2010. 

On May 4, 2004, the Ohio EPA issued a final 
National Pollutant Discharge Elimination System permit 
(the Permit) for J.M. Stuart Station that continued our 
authority to discharge water from the station into the 
Ohio River. During the three-year term of the Permit, 
we conducted a thermal discharge study to evaluate 
the technical feasibility and economic reasonableness 
of water cooling methods other than cooling towers. 
In December 2006, we submitted an application for 
the renewal of the Permit that was due to expire on 
June 30, 2007. In July 2007 we received a draft permit 
proposing to continue our authority to discharge water 
from the station into the Ohio River. On February 5, 
2008 we received a letter from Ohio EPA indicating that 
they intended to impose a compliance schedule as 
part of the final Permit, that requires us to implement 
one of two diffuser options for the discharge of water 
from the station into the Ohio River as identified in the 
thermal discharge study. Subsequently, representatives 
from DP&L and the Ohio EPA have agreed to allow 
DP&L to restrict public access to the water discharge 
area as an alternative to installing one of the diffuser 
options. Ohio EPA issued a revised draft permit that 
was received on November 12, 2008. In December 
2008, the USEPA requested that the Ohio EPA provide 
additional information regarding the thermal discharge 
in the draft permit. In June 2009, DP&L provided 
information to the USEPA in response to their request to 
the Ohio EPA. The timing for issuance of a final permit 
is uncertain.

In September 2009, the USEPA announced that it 
will be revising technology-based regulations govern-
ing water discharges from steam electric generating 
facilities such as J.M. Stuart, Killen and O.H. Hutchings 
Stations. The rulemaking will include the collection of 
information via an industry-wide questionnaire as well 
as targeted water sampling efforts at selected facili-
ties. Subsequent to the information collection effort, it 
is anticipated that the USEPA will release a proposed 
rule in 2011 with final regulations issued in late 2012 or 
early 2013. At present, DP&L is unable to predict the 
impact this rulemaking will have on its operations.

Land Use and Solid Waste Disposal

In September 2002, DP&L and other parties received 
a special notice that the USEPA considers us to be a 
PRP for the clean-up of hazardous substances at the 
South Dayton Dump landfill site. In August 2005, DP&L 
and other parties received a general notice regard-

20  DPL Inc.

ing the performance of a Remedial Investigation and 
Feasibility Study (RI/FS) under a Superfund Alternative 
Approach. In October 2005, DP&L received a special 
notice letter inviting it to enter into negotiations with 
the USEPA to conduct the RI/FS. No recent activity 
has occurred with respect to that notice or PRP status. 
More recently, DP&L has received requests by the 
USEPA and the existing PRP group to allow access to 
be given to DP&L’s service center building site, which 
is across a street from the landfill site. The USEPA 
requested access to drill monitoring and test wells to 
determine the extent of the landfill site’s contamination 
as well as to assess whether certain chemicals used 
at the service center building site might have migrated 
through groundwater to the landfill site. Pursuant to an 
Administrative Order issued by the USEPA requiring 
access to DP&L’s service center building site, DP&L 
has granted such access and drilling of soil borings 
and installation of monitoring wells occurred in the fall 
of 2009. DP&L believes the chemicals used at its ser-
vice center building site were appropriately disposed 
of and have not contributed to the contamination at the 
South Dayton Dump landfill site. While DP&L is unable 
at this time to predict the outcome of this matter, if 
DP&L were required to contribute to the clean-up of 
the site, it could have a material adverse effect on us. 
DP&L is also unable at this time to predict whether 
the monitoring and test wells may lead to any actions 
relating to the service center building site independent 
of the South Dayton Dump clean-up.

In December 2003, DP&L and other parties 
received a special notice that the USEPA considers us 
to be a PRP for the clean-up of hazardous substances 
at the Tremont City landfill site. Information available to 
DP&L does not demonstrate that it contributed hazard-
ous substances to the site. While DP&L is unable at 
this time to predict the outcome of this matter, if DP&L 
were required to contribute to the clean-up of the site, 
it could have a material adverse effect on us.

In November 2007, a PRP group contacted DP&L 
seeking our financial participation in a settlement that 
the group had reached with the federal government 
with respect to the clean-up of an industrial site once 
owned by Carolina Transformer, Inc. DP&L’s business 
records clearly show we did not conduct business  
with Carolina Transformer that would require our partici-
pation in any clean-up of the site. DP&L has declined 
to participate in the clean-up of this site. While DP&L 
is unable at this time to predict the outcome of this 
matter, if DP&L were required to contribute to the 
clean-up of the site, it could have a material adverse 
effect on us.

During 2008, a major spill occurred at an ash pond 

owned by the Tennessee Valley Authority (TVA) as a 
result of a dike failure. The spill generated a significant 
amount of national news coverage, and support for 
tighter regulations for the storage and handling of coal 
combustion products. DP&L has ash ponds at the 
Killen, O.H. Hutchings and J.M. Stuart stations which 
it operates, and also at generating stations operated 
by others but in which DP&L has an ownership inter-
est. We frequently inspect our ash ponds and do not 
anticipate any similar failures. It is widely expected 
that the federal government will propose new regula-
tions covering ash generated from the combustion 
of coal including additional monitoring, testing, or 
construction standards with respect to ash ponds and 
ash landfills. During March 2009, the USEPA, through 
a formal Information Collection Request, collected 
information on ash pond facilities across the coun-
try, including those at Killen and J.M. Stuart stations. 
Subsequently the USEPA collected similar information 
for O.H. Hutchings Station. In addition, during August 
and October 2009, representatives of the USEPA vis-
ited J.M. Stuart Station to collect information on plant 
operations relative to the production and handling of 
by-products. The USEPA’s contractor has issued a draft 
report on their October 2009 visit to J.M. Stuart Station. 
DP&L has provided comments on this document and 
additional related information to the agency. Due to the 
wide range of possible outcomes, DP&L is unable at 
this time to predict the timing or the financial impact of 
any future governmental initiative that may occur.

In addition, as a result of the TVA ash pond spill, 
there has been increasing advocacy to regulate coal 
combustion byproducts as hazardous waste under the 
Resource Conservation Recovery Act, Subtitle C. On 
October 15, 2009, the USEPA provided a draft rule to 
the Office of Management and Budget for interagency 
review. The draft rule proposed to regulate coal ash as 
a hazardous waste, with limited beneficial reuse. DP&L 
is unable at this time to predict the financial impact of 
this regulation, but if coal combustion byproducts are 
regulated as hazardous waste, it is expected to have a 
material adverse impact on operations.

Legal and Other Matters

In February 2007, DP&L filed a lawsuit against a coal 
supplier seeking damages incurred due to the sup-
plier’s failure to supply approximately 1.5 million tons 
of coal to two jointly owned plants under a coal supply 
agreement, of which approximately 570 thousand tons 
was DP&L’s share. DP&L obtained replacement coal 
to meet its needs. The supplier has denied liability, and 

DPL Inc. 

21

 
is currently in federal bankruptcy proceedings. DP&L 
is unable to determine the ultimate resolution of this 
matter at this time. In accordance with GAAP, DP&L 
has not recorded any assets relating to this lawsuit.

On May 16, 2007, DPL filed a claim with Energy 

Insurance Mutual (EIM) to recoup legal expenses  
associated with our litigation against certain former 
executives. Arbitration on that claim occurred on May 
13, 2009. The arbitration panel issued a ruling in Phase 
1 of the arbitration on September 25, 2009, finding  
that most of the claims involving the former executives 
were covered. The matter is pending.

As a member of PJM, DP&L is also subject to 
charges and costs associated with PJM operations as 
approved by the FERC. FERC Orders issued in 2007 
regarding the allocation of costs of large transmission 
facilities within PJM, could result in additional costs 
being allocated to DP&L of approximately $12 mil-
lion or more annually by 2012. DP&L filed a notice of 
appeal to the U.S. Court of Appeals, D.C. Circuit on 
March 18, 2008 challenging the allocation method. 
The appeal was consolidated with other appeals taken 
by other interested parties of the same FERC Orders 
and the consolidated cases were assigned to the 7th 
Circuit. On August 6, 2009, the 7th Circuit ruled that the 
FERC had failed to provide a reasoned basis for the 
allocation method it had approved. Rehearings were 
filed by other interested litigants and denied by the 
Court, which then remanded the matter to the FERC for 
further proceedings. On January 21, 2010, the FERC 
issued a procedural order on remand establishing  
a paper hearing process under which PJM will make 
an informational filing in late February. Subsequently 
PJM and other parties, including DP&L, will be able 
to file initial comments, testimony, and recommenda-
tions and reply comments. Absent future changes to 
the procedural schedule that may occur for a number 
of reasons including if settlement discussions are held, 
the paper hearing process should be complete and  
the case ready for FERC consideration in 2010. FERC 
did not establish a deadline for its issuance of a sub-
stantive order. DP&L cannot predict the timing or the 
likely outcome of the proceeding. Until such time  
as FERC may act to approve a change in methodology, 
PJM will continue to apply the allocation methodology 
that had been approved by FERC in 2007. Although we 
continue to maintain that these costs should be borne 
by the beneficiaries of these projects and that DP&L 

is not one of these beneficiaries, any new credits or 
additional costs resulting from the ultimate outcome of 
this proceeding will be reflected in DP&L’s TCRR rider 
which is already in place to pass through RTO-related 
costs and credits.

In June 2009, the NERC, a FERC-certified electric 
reliability organization responsible for developing and 
enforcing mandatory reliability standards, commenced 
a routine audit of DP&L’s operations. The audit, which 
was for the period June 18, 2007 to June 25, 2009, 
evaluated DP&L’s compliance with 42 requirements 
in 18 NERC-reliability standards. DP&L is currently 
subject to a compliance audit at a minimum of once 
every three years as provided by the NERC Rules of 
Procedure. This audit was concluded in June 2009 and 
its findings revealed that DP&L had some Possible 
Alleged Violations (PAVs) associated with five NERC 
Reliability Standards. In response to the report, DP&L 
filed mitigation plans with NERC to address the PAVs. 
These mitigation plans have been accepted and DP&L 
is currently awaiting a proposal for settlement from 
NERC. While we are currently unable to determine the 
extent of penalties, if any, that may be imposed on 
DP&L, we do not believe such penalties will have a 
material impact on our results of operations.

Capital Expenditures for Environmental Matters

Test operations of the FGD equipment on our jointly-
owned Conesville Unit 4 were completed in November 
2009. The equipment is currently in service.

DPL’s construction additions were approximately 

$145 million, $228 million and $347 million in 2009, 
2008 and 2007, respectively, and are expected to 
approximate $210 million in 2010. Planned construction 
additions for 2010 relate primarily to new investments 
in and upgrades to DP&L’s power plant equipment and 
transmission and distribution system.

DP&L’s construction additions were $144 million, 
$225 million and $344 million in 2009, 2008 and 2007, 
respectively, and are expected to approximate $200 
million in 2010. Planned construction additions for 2010 
relate primarily to new investments in and upgrades to 
DP&L’s power plant equipment and transmission and 
distribution system.

All environmental additions made during the past 

three years pertain to DP&L and approximate $21 
million, $90 million and $209 million in 2009, 2008 and 
2007, respectively.

Item 1A Risk Factors

This annual report and other documents that we file 
with the SEC and other regulatory agencies, as well as 
other written or oral statements we may make from time 
to time, contain information based on management’s 
beliefs and include forward-looking statements (within 
the meaning of the Private Securities Litigation Reform 
Act of 1995) that involve a number of known and 
unknown risks, uncertainties and assumptions. These 
forward-looking statements are not guarantees of future 
performance and there are a number of factors includ-
ing, but not limited to, those listed below, which could 
cause actual outcomes and results to differ materially 
from the results contemplated by such forward-looking 
statements. We do not undertake any obligation to 
publicly update or revise any forward-looking state-
ments, whether as a result of new information, future 
events or otherwise. These forward-looking statements 
are generally identified by terms and phrases such as 
“anticipate,” “believe,” “intend,” “estimate,” “expect,” 
“continue,” “should,” “could,” “may,” “plan,” “project,” 
“predict,” “will” and similar expressions.

Future operating results are subject to fluctuations 
based on a variety of factors, including but not limited 
to: unusual weather conditions; catastrophic weather-
related damage; unscheduled generation outages; 
changes in wholesale power sales prices; unusual 
maintenance or repairs; changes in fuel and purchased 
power costs, emissions allowance costs, or availability 
constraints; environmental compliance; and electric 
transmission system constraints.

The following is a listing of specific risk factors that 

DPL and DP&L consider to be the most significant to 
your decision to invest in our securities. If any of these 
events occur or are continuing, our business, results  
of operations, financial condition and cash flows could 
be materially affected.

Regulation and Litigation 

We are subject to extensive laws and regulation by 
federal, state and local authorities, such as the PUCO, 
the USEPA, the Ohio EPA, the FERC, the SEC and the 
Internal Revenue Service, among others. Regulations 
affect almost every aspect of our business, includ-
ing in the areas of the environment, health and safety, 
cost recovery and rate making, securities, corporate 
governance, public disclosure and reporting and taxa-

tion. New laws and regulations, and new interpretations 
of existing laws and regulations, are ongoing and we 
generally cannot predict the future course of changes 
in this regulatory environment or the ultimate effect that 
this changing regulatory environment will have on our 
business. Complying with this regulatory environment 
requires us to expend a significant amount of funds 
and resources. The failure to comply with this regulato-
ry environment could subject us to substantial financial 
costs and penalties and changes, either forced or vol-
untary, in the way we operate our business. Additional 
detail about the effect of this regulatory environment 
on our operations is included in the risk factors set 
forth below. In the normal course of business, we are 
also subject to various lawsuits, actions, proceedings, 
claims and other matters asserted under this regulatory 
environment, which require us to expend significant 
funds to address, the outcomes of which are uncer-
tain and the adverse resolutions of which could have 
a material adverse effect on our results of operations, 
financial condition and cash flows.

Cost Recovery and Rates 

The costs we can recover and the return on capital we 
are permitted to earn for certain aspects of our busi-
ness are regulated and governed by the laws of Ohio 
and the rules, policies and procedures of the PUCO. 
On May 1, 2008, SB 221, an Ohio electric energy bill, 
was signed by the Governor of Ohio and became 
effective July 31, 2008. This law, among other things, 
required all Ohio distribution utilities to file either an 
electric security plan or a market rate option that was 
to be in effect on January 1, 2009, and established a 
significantly excessive earnings test for Ohio public 
utilities based on the earnings of other companies 
with similar business and financial risks. The PUCO 
approved DP&L’s filed electric security plan on June 
24, 2009. DP&L’s electric security plan provides, 
among other things, that DP&L’s existing rate plan 
structure will continue through 2012; that DP&L may 
seek recovery for adjustments to its existing rate plan 
structure for costs associated with storm damage,  
regulatory and tax changes, new climate change or 
carbon regulations, fuel and purchased power and  
certain other costs; and that SB 221’s significantly 
excessive earnings test will not apply to DP&L until 
2012. DP&L’s electric security plan, and certain 
filings made by us in connection with this plan, are 

DPL Inc.

further discussed under “Ohio Retail Rates” in Item 1 – 
Competition and Regulation.

While rate regulation is premised on full recovery 
of prudently incurred costs and a reasonable rate of 
return on invested capital, there can be no assurance 
that the PUCO will agree that all of our costs have 
been prudently incurred or are recoverable or that the 
regulatory process in which rates are determined will 
always result in rates that will produce a full or timely 
recovery of our costs and permitted rates of return. 
Certain of our cost recovery riders are also by-pass-
able by some of our customers. Accordingly, the rates 
DP&L is allowed to charge may or may not match its 
expenses at any given time. Therefore, DP&L could be 
subject to prevailing market prices for electricity and 
would not necessarily be able to charge rates that pro-
duce timely or full recovery of its expenses. Changes 
in, or reinterpretations of, the laws, rules, policies  
and procedures that set electric rates and permitted 
rates of return; changes in DP&L’s ability to recover 
expenditures for environmental compliance, reliability 
initiatives, purchased power and fuel (which account 
for a substantial portion of our operating costs), capital 
expenditures and investments and other costs on a 
fully or timely basis through rates; and changes to the 
frequency and timing of rate increases could have a 
material adverse effect on our results of operations, 
financial condition and cash flows.

Advanced Energy and Energy Efficiency Requirements

SB 221 contains targets relating to advanced energy, 
renewable energy, peak demand reduction and energy 
efficiency standards. The standards require that, by 
the year 2025 and each thereafter, 25% of the total 
number of kWh of electricity sold by the utility to retail 
electric consumers must come from alternative energy 
resources, which include “advanced energy resources” 
such as distributed generation, clean coal, advanced 
nuclear, energy efficiency and fuel cell technology; 
and “renewable energy resources” such as solar, 
hydro, wind, geothermal and biomass. At least half of 
the 25% must be generated from renewable energy 
resources, including 0.5% from solar energy, and the 
remainder must be generated from advanced energy 
sources. Annual renewable energy standards began 
in 2009 with increases in required percentages each 
year through 2024. The advanced energy standard 
must be met by 2025 and each year thereafter. Annual 
targets for energy efficiency began in 2009 and require 
increasing energy reductions each year compared 
to a baseline energy usage, up to 22.3% by 2025. 
Peak demand reduction targets began in 2009 with 
increases in required percentages each year, up to 

7.75% by 2018. The advanced energy and renewable 
energy standards are expected to increase (and could 
increase materially) our power supply costs. Pursuant 
to DP&L’s approved electric security plan, DP&L is 
entitled to recover costs associated with its alterna-
tive energy plans, as well as its energy efficiency and 
demand response programs, and DP&L began recov-
ering these costs in 2009. If in the future we are unable 
to timely or fully recover these costs, it could have a 
material adverse effect on our results of operations, 
financial condition and cash flows. In addition, if we 
were found not to be in compliance with these stan-
dards, monetary penalties could apply. These penalties 
are not permitted to be recovered from customers and 
significant penalties could have a material adverse 
effect on our results of operations, financial condition 
and cash flows. The demand reduction and energy effi-
ciency standards by design result in reduced energy 
and demand that could adversely affect our results of 
operations, financial condition and cash flows.

Availability and Cost of Fuel 

We purchase coal, natural gas and other fuel from a 
number of suppliers. The coal market in particular has 
experienced significant price volatility in the last sev-
eral years. We are now in a global market for coal in 
which our domestic price is increasingly affected by 
international supply disruptions and demand balance. 
Coal exports from the U.S. have increased significantly 
in recent years. In addition, domestic issues like gov-
ernment-imposed direct costs and permitting issues 
that affect mining costs and supply availability, the vari-
able demand of retail customer load and the variable 
performance of our generation fleet have an impact on 
our fuel procurement operations. Our approach is to 
hedge the fuel costs for our anticipated electric sales. 
However, we may not be able to hedge the entire expo-
sure of our operations from fuel price volatility. As of the 
date of this report, we have hedged our coal require-
ments with coal mine operators and financial institu-
tions to meet our committed burn through December 
31, 2010. Historically, some of our suppliers and buy-
ers of fuel have not performed on their contracts and 
have failed to deliver or accept fuel as specified under 
their contracts. To the extent our suppliers and buyers 
do not meet their contractual commitments, we cannot 
secure adequate fuel or sell excess fuel in a timely  
or cost-effective manner or we are not hedged against 
price volatility, our results of operations, financial con-
dition and cash flows could be materially adversely 
affected. In addition, DP&L is a co-owner of certain 
generation facilities where it is a non-operating partner. 
DP&L does not procure or have control over the fuel 

24  DPL Inc.

for these facilities, but is responsible for its proportion-
ate share of the cost of fuel procured at these facilities. 
Co-owner operated facilities do not always have real-
ized fuel costs that are equal to our co-owners’ projec-
tions, and we are responsible for our proportionate 
share of any increase in actual fuel costs. Pursuant to 
its electric security plan, DP&L implemented a fuel and 
purchased power recovery mechanism beginning on 
January 1, 2010, which will track and adjust fuel costs 
on a seasonal quarterly basis. If in the future we are 
unable to timely or fully recover our fuel costs, it could 
have a material adverse effect on our results of opera-
tions, financial condition and cash flows. 

Commodity Trading

We trade coal, power and other commodities to hedge 
our positions in these commodities. These trades are 
impacted by a range of factors, including variations in 
power demand, fluctuations in market prices, market 
prices for alternative commodities and optimization 
opportunities. We have attempted to manage our com-
modities trading risk exposure by establishing and 
enforcing risk limits and risk management policies. 
Despite our efforts, however, these risk limits and man-
agement policies may not work as planned and fluc-
tuating prices and other events could adversely affect 
our results of operations, financial condition and cash 
flows. As part of our risk management, we use a variety 
of non-derivative and derivative instruments, such as 
swaps, futures and forwards, to manage our market 
risks. In the absence of actively quoted market prices 
and pricing information from external sources, the valu-
ation of some of these derivative instruments involves 
management’s judgment or use of estimates. As a 
result, changes in the underlying assumptions or use of 
alternative valuation methods could affect the reported 
fair value of some of these contracts. We could also 
recognize financial losses as a result of volatility in 
the market values of these contracts or if a counter-
party fails to perform, which could result in a material 
adverse effect on our results of operations, financial 
condition and cash flows. 

Environmental Compliance 

Our operations and facilities (both wholly-owned and 
co-owned with others) are subject to numerous and 
extensive federal, state and local environmental laws 
and regulations relating to air quality (such as reduc-
ing NOx, SO2, SO3 (sulfur trioxide) and mercury emis-
sions and potential future control of GHG emissions as 
discussed in more detail in the next risk factor), water 
quality, wastewater discharge, solid waste (such as 
the potential future regulation of ash generated from 

coal-based generating stations), hazardous waste and 
health and safety. With respect to our largest genera-
tion station, the J.M. Stuart Station, we are also subject 
to continuing compliance requirements related to NOx, 
SO2 and particulate matter emissions under DP&L’s 
consent decree with the Sierra Club. Compliance with 
these laws, regulations and other requirements requires 
us to expend significant funds and resources. These 
expenditures have been significant in the past and we 
expect that they will increase in the future. Complying 
with these numerous requirements could at some point 
become prohibitively expensive and result in our shut-
ting down (temporarily or permanently) or altering the 
operation of our facilities. Environmental laws and regu-
lations also generally require us to obtain and comply 
with a wide variety of environmental licenses, permits, 
inspections and other approvals. If we are not able 
to timely obtain, maintain or comply with all licenses, 
permits, inspections and approvals required to operate 
our business, then our operations could be prevented, 
delayed or subject to additional costs. Failure to com-
ply with environmental laws, regulations and other 
requirements may result in the imposition of fines and 
penalties and the imposition of stricter environmental 
standards and controls and other injunctive measures 
affecting operating assets. In addition, any alleged 
violation of these laws, regulations and other require-
ments may require us to expend significant resources 
to defend against any such alleged violations. We own 
a non-controlling interest in several generating sta-
tions operated by our co-owners. As a non-controlling 
owner in these generating stations, we are responsible 
for our pro rata share of expenditures for complying 
with environmental laws, regulations and other require-
ments, but have limited control over the compliance 
measures taken by our co-owners. DP&L has an EIR in 
place as part of its existing rate plan structure, the last 
increase of which occurs in 2010 and remains at that 
level through 2012. In addition, DP&L’s electric security 
plan permits it to seek recovery for costs associated 
with new climate change or carbon regulations. While 
we expect to recover certain environmental costs and 
expenditures from customers, if in the future we are 
unable to fully recover our costs in a timely manner 
it could have a material adverse effect on our results 
of operations, financial condition and cash flows. In 
addition, if we were found not to be in compliance with 
these environmental laws, regulations or requirements, 
any penalties that would apply would likely not be 
recoverable from customers and could have a material 
adverse effect on our results of operations, financial 
condition and cash flows.

Regulation of GHGs

There is a growing concern nationally and internation-
ally among regulators, investors and others concerning 
global climate change and the contribution of emis-
sions of GHG, including most significantly, CO2. This 
concern has led to increased interest in legislation and 
action at the federal and state levels, as well as litiga-
tion, relating to GHG emissions, including a recent 
declaration by the USEPA that GHGs pose a danger to 
the public health that may allow the USEPA to directly 
regulate greenhouse emissions. There have been vari-
ous GHG legislative proposals introduced in Congress 
(with one bill passed by the House of Representatives 
in 2009) and there is growing consensus that some 
form of legislation of GHG emissions will be approved 
at the federal level that could result in substantial 
additional costs in the form of taxes or emission allow-
ances. Approximately 99% of the energy we produce 
is generated by coal. If legislation or regulations are 
passed at the federal or state levels imposing manda-
tory reductions of CO2 and other GHGs on generation 
facilities, we could be required to make large additional 
capital investments. Legislation and regulations could 
also impair the value of our generation stations or 
make some of these stations uneconomical to maintain 
or operate and it could raise uncertainty about the 
future viability of fossil fuels, particularly coal, as an 
energy source for new and existing generation stations. 
Although DP&L is permitted under its current electric 
security plan to seek recovery of costs associated  
with new climate change or carbon regulations, our 
inability to fully or timely recover such costs could have 
a material adverse effect on our results of operations, 
financial condition and cash flows.

Sales of Excess Emission Allowances

DP&L has a program for selling excess emission allow-
ances. During 2009 and 2008, DP&L sold excess 
emission allowances to various counterparties realizing 
total net gains of $5.0 million and $34.8 million, respec-
tively. Sales of excess emission allowances are impact-
ed by a range of factors, such as general economic 
conditions, fluctuations in market demand, availability 
of excess inventory available for sale and changes to 
the regulatory environment, including the status of the 
USEPA’s CAIR. These factors could cause the amount 
of excess emission allowances we sell to fluctuate, 
which could cause a material adverse effect on our 
results or operations, financial condition and cash flows 
for any particular period.

On July 11, 2008, the United States Court of 
Appeals for the District of Columbia Circuit issued a 

decision that vacated the CAIR and its associated 
Federal Implementation Plan. This decision remanded 
these issues back to the USEPA. The USEPA issued 
CAIR on March 10, 2005 to regulate certain upwind 
states with respect to fine particulate matter and 
ozone. CAIR created interstate trading programs for 
annual NOx emission allowances and made modifica-
tions to an existing trading program for SO2 that were 
to take effect in 2010. The district court’s decision, in 
part, invalidated the new NOx annual emission allow-
ance trading program and the modifications to the 
SO2 emission trading program and created uncertainty 
regarding future NOx and SO2 emission reduction 
requirements and their timing. On December 23, 2008, 
the court reversed part of its decision that vacated 
CAIR. Thus, CAIR currently remains in effect, but the 
USEPA remains subject to the district court’s order to 
revise the program. In January 2010, the Court ordered 
the USEPA to file a response to request for a USEPA 
decision filed by parties in the original case who are 
now seeking a Court order to require the USEPA to 
issue new regulations by March 1, 2010. We cannot at 
this time predict the timing or the outcome of any new 
regulations relating to CAIR.

DP&L’s program for selling excess emission allow-

ances includes sales of annual NOx emission allow-
ances and SO2 emission allowances that were the sub-
ject of CAIR trading programs. Although we continue 
selling emission allowances, the district court’s CAIR 
decision has affected the emission allowance trad-
ing market and DP&L’s program for selling additional 
excess allowances. The long-term impact of the district 
court’s decision, and of the actions the USEPA or oth-
ers will take in response to this decision, on DPL and 
DP&L is not fully known at this time, but could affect 
the amount of excess emission allowances we sell and 
thus have an adverse effect on us.

Customer Switching 

Customers can elect to take generation service from 
a CRES provider offering services to customers in 
DP&L’s service territory. Although retail generation 
service has been a competitive service since January 
1, 2001, the competitive generation market has not 
developed to date in DP&L’s service territory to any 
significant degree. As of December 31, 2009, six unaf-
filiated CRES providers have been certified by the 
PUCO to provide generation service to DP&L custom-
ers. DPLER, a wholly-owned subsidiary of DPL, is also 
a certified CRES provider and accounted for 99% of 
the total kWh consumed by customers served by CRES 
providers in DP&L’s service territory in 2009. Increased 
competition by CRES providers in our service territory 

26  DPL Inc.

for retail generation service could result in the loss of 
existing customers and increased costs to retain or 
attract customers, which could have a material adverse 
effect on our results of operations, financial condition 
and cash flows. The following are a few of the factors 
that could result in increased switching by customers 
to CRES providers in the future:

n Low wholesale price levels could lead to existing 
CRES providers becoming more active in our service 
territory, and new CRES providers entering our territory. 

n We could also experience customer switching 
through “governmental aggregation,” where a munici-
pality may contract with a CRES provider to provide 
generation service to the customers located within the 
municipal boundaries. Several communities in DP&L’s 
service territory passed ordinances during 2003-2004 
allowing them to become government aggregators. To 
date, no aggregation program has been implemented. 

n Increased customer switching in other Ohio utility 
service territories could lead to new market entrants 
and more aggressive measures to secure customers 
by CRES providers.

Operation and Performance of Facilities

The operation and performance of our generation, 
transmission and distribution facilities and equipment 
is subject to various events and risks, such as the 
potential breakdown or failure of equipment, processes 
or facilities, fuel supply or transportation disruptions, 
the loss of cost-effective disposal options for solid 
waste generated by our facilities (such as gypsum), 
accidents, injuries, labor disputes or work stoppages 
by employees, operator error, acts of terrorism or 
sabotage, construction delays or cost overruns, short-
ages of or delays in obtaining equipment, material 
and labor, operational restrictions resulting from envi-
ronmental limitations and governmental interventions, 
performance below expected levels, weather-related 
and other natural disruptions, vandalism, events occur-
ring on the systems of third parties that interconnect 
to and affect our system and the increased costs and 
enhanced risks associated with our aging generation 
units. Our results of operations, financial condition and 
cash flows could be adversely affected due to the hap-
pening or continuation of these events.

Operation of our owned and co-owned generating 
stations below expected capacity levels, or unplanned 
outages at these stations, could cause reduced energy 
output and efficiency levels and likely result in lost 
revenues and increased expenses that could have a 
material adverse effect on our results of operations, 

financial condition and cash flows. In particular, since 
over 50% of our base-load generation is derived 
from co-owned generation stations operated by our 
co-owners, poor operational performance by our co-
owners, misalignment of co-owners’ interests or lack 
of control over costs (such as fuel costs) incurred at 
these stations could have an adverse effect on us. We 
have constructed and placed into service FGD facili-
ties at most of our base-load generating stations. If 
there is significant operational failure of the FGD equip-
ment at the generating stations, we may not be able to 
meet emission requirements at some of our generat-
ing stations or, at other stations, it may require us to 
burn more expensive cleaner coal or utilize emission 
allowances. These events could result in a substantial 
increase in our operating costs. Depending on the 
degree, nature, extent, or willfulness of any failure  
to comply with environmental requirements, including 
those imposed by the Consent Decree, such non- 
compliance could result in the imposition of penalties 
or the shutting down of the affected generating  
stations, which could have a material adverse effect  
on our results of operations, financial condition and 
cash flows.

Asbestos and other regulated substances are,  
and may continue to be, present at our facilities where  
suitable alternative materials are not available. 
Although we believe that any asbestos at our facili-
ties is contained and suitable, we have been named 
as a defendant in pending asbestos litigation, which 
at this time is not material to us. The continued pres-
ence of asbestos and other regulated substances 
at these facilities could result in additional litigation 
being brought against us, which could have a material 
adverse effect on our results of operations, financial 
condition and cash flows. 

Reliability Standards

As an owner and operator of a bulk power transmission 
system, DP&L is subject to mandatory reliability stan-
dards promulgated by the NERC and enforced by the 
FERC. The standards are based on the functions that 
need to be performed to ensure the bulk power system 
operates reliably and is guided by reliability and mar-
ket interface principles. In addition, DP&L is subject to 
new Ohio reliability standards and targets. Compliance 
with reliability standards subjects us to higher operat-
ing costs or increased capital expenditures. While 
we expect to recover costs and expenditures from 
customers through regulated rates, there can be no 
assurance that the PUCO will approve full recovery in 
a timely manner. If we were found not to be in compli-
ance with the mandatory reliability standards, we could 

DPL Inc. 

27

 
be subject to sanctions, including substantial monetary 
penalties, which likely would not be recoverable from 
customers through regulated rates and could have  
a material adverse effect on our results of operations, 
financial condition and cash flows.

Weather Conditions

Weather conditions significantly affect the demand for 
electric power. In our Ohio service territory, demand for 
electricity is generally greater in the summer months 
associated with cooling and in the winter months asso-
ciated with heating as compared to other times of the 
year. Unusually mild summers and winters could there-
fore have an adverse effect on our results of opera-
tions, financial condition and cash flows. In addition, 
severe or unusual weather, such as hurricanes and 
ice or snow storms, may cause outages and property 
damage that may require us to incur additional costs 
that may not be insured or recoverable from custom-
ers. While DP&L is permitted to seek recovery of storm 
damage costs under its electric security plan, if DP&L 
is unable to fully recover such costs in a timely manner, 
it could have a material adverse effect on our results  
of operations, financial condition and cash flows.

Regional Transmission Organizational Risks

On October 1, 2004, in compliance with Ohio law, 
DP&L turned over control of its transmission func-
tions and fully integrated into PJM. The price at which 
we can sell our generation capacity and energy is 
now determined through supply and demand and the 
behavior of market participants. While we can continue 
to make bilateral transactions to sell our generation 
through a willing-buyer and willing-seller relationship, 
any transactions that are not pre-arranged are subject 
to market conditions at PJM. To the extent we sell elec-
tricity into the power markets on a contractual basis, 
we are not guaranteed any rate of return on our capital 
investments through mandated rates. These sales are 
dependent upon prevailing market prices, which could 
fluctuate substantially over relatively short periods of 
time and adversely affect our results of operations, 
financial condition and cash flows. The rules governing 
the various regional power markets also change from 
time to time which could affect our costs and revenues. 
We incur fees and costs to participate in the RTO. 
We may be limited with respect to the price at which 
power may be sold from certain generating units and 
we may be required to expand our transmission system 
according to decisions made by the RTO rather than 
our internal planning process. While RTO transmission 
rates were initially designed to be revenue neutral, 
various proposals and proceedings currently taking 
place at FERC may cause transmission rates to change 

from time to time. In addition, developing rules associ-
ated with the allocation and methodology of assigning 
costs associated with improved transmission reliability, 
reduced transmission congestion and firm transmission 
rights may have a financial impact on us. While the 
impact of the capacity market and other RTO develop-
ments on us at any given time will depend on a variety 
of factors, including the market behavior of various par-
ticipants, our results of operations, financial condition 
and cash flows could be materially adversely affected. 
Future capacity auction results will be dependent not 
only on the overall supply and demand of generation 
and load, but also by congestion and PJM’s business 
rules relating to bidding for Demand Response and 
Energy Efficiency resources in the auctions. The PJM 
RPM base residual auction for the 2012/2013 period 
cleared at a per megawatt price of $16/day for our 
RTO area. Prior to this auction, the per megawatt price 
for the 2011/2012 period was $110/day. We cannot 
predict the outcome of future auctions, but if the cur-
rent auction price is sustained or there is continued 
volatility in the auction market, our results of operations, 
financial condition and cash flows could be materially 
adversely affected.

SB 221 includes a provision that allows electric 
utilities to seek and obtain deferral and recovery of 
RTO related charges. If in the future, however, we are 
unable to defer or recover all of these cost in a timely 
manner, it could have a material adverse effect  
on our results of operations, financial condition and 
cash flows.

As members of PJM, DP&L and DPLE are subject 

to certain additional risks including those associated 
with the allocation among PJM members of losses 
caused by unreimbursed defaults of other participants 
in PJM markets and those associated with complaint 
cases filed against PJM that may seek refunds of rev-
enues previously earned by PJM members including 
DP&L and DPLE. These amounts could be significant 
and have a material adverse effect on our results of 
operations, financial condition and cash flows.

PJM Infrastructure Risks

Annually, PJM performs a review of the capital addi-
tions required to provide reliable electric transmission 
services throughout its territory. PJM traditionally allo-
cated the costs of constructing these facilities to those 
entities that benefited directly from the additions. On 
April 19, 2007, the FERC issued an order that modified 
the traditional method of allocating costs associated 
with new high voltage planned transmission facilities. 
FERC ordered that the cost of new high-voltage facili-
ties be socialized across the PJM region. The costs of 
the new facilities at lower voltages will continue to be 

28  DPL Inc.

assigned to the load centers that benefit from the new 
facilities. With respect to the socialization of new high 
voltage facilities, DP&L filed a notice of appeal to the 
U.S. Court of Appeals, D.C. Circuit on March 18, 2008 
challenging the allocation method. The appeal was 
consolidated with other appeals taken by other peti-
tioners of the same FERC Orders and the consolidated 
cases were assigned to the 7th Circuit. On August 6, 
2009, the 7th Circuit ruled that the FERC had failed 
to provide a reasoned basis for the allocation method 
for new high voltage facilities that it had approved. 
Subsequently, the 7th Circuit denied other petition-
ers’ rehearing requests and remanded the case to the 
FERC for further proceedings. Until such time as FERC 
may act to approve a change in methodology, PJM will 
continue to apply the allocation methodology that had 
been approved by FERC in 2007. At this time, DP&L 
is unable to predict the outcome of this matter. The 
overall impact of FERC’s allocation methodology can-
not be definitively assessed at this time because not 
all new planned construction is likely to happen. The 
additional costs allocated to DP&L for new large trans-
mission approved projects were immaterial in 2009 
and are not expected to be material in 2010, but could 
rise to approximately $12 million or more annually by 
2012. DP&L sought and obtained PUCO authority to 
defer and recover costs associated with these new 
high-voltage transmission projects through retail rates. 
However, if in the future we are unable to defer or 
recover these costs, it could have a material adverse 
effect on our results of operations, financial condition 
and cash flows.

Credit and Capital Markets

From time to time we rely on access to the credit and 
capital markets to fund certain of our operational and 
capital costs. These capital and credit markets have 
experienced extreme volatility and disruption and the 
ability of corporations to obtain funds through the issu-
ance of debt or equity has been negatively impacted. 
Disruptions in the credit and capital markets make  
it harder and more expensive to obtain funding for our 
business. Access to funds under our existing financing 
arrangements is also dependent on the ability of our 
counterparties to meet their financing commitments. 
Our inability to obtain financing on reasonable terms, or 
at all, with creditworthy counterparties could adversely 
affect our results of operations, financial condition and 
cash flows. If our available funding is limited or we are 
forced to fund our operations at a higher cost, these 
conditions may require us to curtail our business activi-
ties and increase our cost of funding, both of which 
could reduce our profitability. DP&L’s variable rate debt 

bears interest based on a prevailing rate that is reset 
weekly based on a market index that can be affected 
by market demand, supply, market interest rates and 
other market conditions. We also currently maintain 
both cash on deposit and investments in cash equiva-
lents that could be adversely affected by interest rate 
fluctuations. In addition, select debt of DPL and DP&L 
is currently rated investment grade by various rating 
agencies. If the rating agencies were to rate DPL and 
DP&L below investment grade, our borrowing costs 
would increase, we would likely be required to pay a 
higher interest rate under certain existing and future 
financings and our potential pool of investors and fund-
ing sources would likely decrease. Our credit ratings 
also govern the collateral provisions of certain of our 
contracts, and a below investment grade credit rating 
by one of the rating agencies could require us to post 
cash collateral under these contracts. These events 
would likely reduce our liquidity and profitability and 
could have a material adverse effect on our results of 
operations, financial condition and cash flows.

Value and Funding of Benefit Plan Assets

The performance of the capital markets affects the 
values of the assets that are held in trust to satisfy 
future obligations under our pension and postretire-
ment benefit plans. These assets are subject to market 
fluctuations and will yield uncertain returns, which may 
fall below our projected return rates. A decline in the 
market value of the pension and postretirement ben-
efit plan assets will increase the funding requirements 
under our pension and postretirement benefit plans if 
the actual asset returns do not recover these declines 
in value in the foreseeable future. Future pension 
funding requirements, and the timing of funding pay-
ments, may also be subject to changes in legislation. 
The Pension Protection Act, enacted in August 2006, 
requires underfunded pension plans to improve their 
funding ratios within prescribed intervals based on the 
level of their underfunding. As a result, our required 
contributions to these plans may increase in the future. 
In addition, our pension and postretirement benefit plan 
liabilities are sensitive to changes in interest rates. As 
interest rates decrease, the liabilities increase, poten-
tially increasing benefit expense and funding require-
ments. Further, changes in demographics, including 
increased numbers of retirements or changes in life 
expectancy assumptions, may also increase the fund-
ing requirements of the obligations related to the pen-
sion and other postretirement benefit plans. Declines 
in market values and increased funding requirements 
could have a material adverse effect on our results of 
operations, financial condition and cash flows. 

DPL Inc. 

29

 
Reliance on Third Parties

We enter into transactions with and rely on many coun-
terparties in connection with our business, including for 
the purchase and delivery of inventory, which includes 
fuel and equipment components (such as limestone for 
our FGD equipment), for our capital improvements and 
additions and to provide professional services, such as 
actuarial calculations, payroll processing and various 
consulting services. If any of these counterparties fails 
to perform its obligations to us or becomes unavail-
able, our business plans may be materially disrupted, 
we may be forced to discontinue certain operations if a 
cost-effective alternative is not readily available or we 
may be forced to enter into alternative arrangements at 
then-current market prices that may exceed our con-
tractual prices and cause delays. These events could 
cause our results of operations, financial condition and 
cash flows to be materially adversely affected.

Our Stock Price May Fluctuate

The market price of DPL’s common stock has fluctu-
ated over a relatively wide range. Over the past three 
years, the market price of our common stock has fluc-
tuated with a low of $19.16 and a high of $31.91. Our 
common stock in recent years has experienced signifi-
cant price and volume variations that have often been 
unrelated to our operating performance. Over the pre-
vious year, the global markets have increasingly been 
characterized by substantially increased volatility in 
companies in a number of industries and in the broad-
er markets. The market price of our common stock 
may continue to significantly fluctuate in the future and 
may be affected adversely by factors such as actual or 
anticipated change in our operating results, acquisition 
activity, changes in financial estimates by securities 
analysts, general market conditions, rumors and other 
factors, which factors may increase price volatility  
and be exacerbated by continued disruption in the 
global markets at large.

Economic Conditions and Markets

Economic pressures, as well as changing market con-
ditions and other factors related to physical energy and 
financial trading activities, which include price, credit, 
liquidity, volatility, capacity, transmission and interest 
rates, can have a significant effect on our operations 
and the operations of our retail, industrial and com-
mercial customers and our suppliers. The direction 
and relative strength of the global economy has been 
increasingly uncertain due to softness in the real estate 
and mortgage markets, volatility in fuel and other 
energy costs, difficulties in the financial services sector 
and credit markets, increased unemployment and other 

factors. Many of these factors have disproportionately 
impacted our Ohio service territory.

Our results of operations, financial condition and 
cash flows may be negatively affected by sustained 
downturns or a sluggish economy. Sustained down-
turns, recession or a sluggish economy generally affect 
the markets in which we operate and negatively influ-
ence our energy operations. A contracting, slow or 
sluggish economy could reduce the demand for ener-
gy in areas in which we are doing business. During 
economic downturns, our commercial and industrial 
customers may see a decrease in demand for their 
products, which in turn may lead to a decrease in the 
amount of energy they require. In addition, our custom-
ers’ ability to pay us could also be impaired, which 
could result in an increase in receivables and write-offs 
of uncollectible accounts. Our suppliers could also be 
affected by the economic downturn resulting in supply 
delays or unavailability. Reduced demand for our elec-
tric services, failure by our customers to timely remit full 
payment owed to us and supply delays or unavailability 
could have a material adverse effect on our results of 
operations, financial condition and cash flows.

Warrant Exercise 

DPL’s warrant holders can exercise their warrants to 
purchase shares of DPL common stock at their discre-
tion until March 12, 2012. As of the date of this report, 
the number of outstanding warrants is 1.8 million. As a 
result, DPL could be required to issue up to 1.8 million 
common shares in exchange for the receipt of the exer-
cise price of $21.00 per share or pursuant to a cash-
less exercise process. The exercise of warrants would 
increase the number of common shares outstanding 
and increase our common share dividend costs, thus 
affecting any existing guidance on EPS and adversely 
affecting our financial condition and cash flows.

Internal Controls and Information Reporting

Our internal controls, accounting policies and prac-
tices and internal information systems are designed 
to enable us to capture and process transactions and 
information in a timely and accurate manner in compli-
ance with GAAP in the United States of America, laws 
and regulations, taxation requirements and federal 
securities laws and regulations in order to, among other 
things, disclose and report financial and other informa-
tion in connection with the recovery of our costs and 
with our reporting requirements under federal securi-
ties, tax and other laws and regulations and to properly 
process payments. We have implemented corporate 
governance, internal control and accounting policies 
and procedures in connection with the Sarbanes-Oxley 
Act of 2002 (the “Act”). Our internal controls and poli-

30  DPL Inc.

cies have been and continue to be closely monitored 
by management and our Board of Directors to ensure 
continued compliance with Section 404 of the Act. 
While we believe these controls, policies, practices 
and systems are adequate to verify data integrity, 
unanticipated and unauthorized actions of employees, 
temporary lapses in internal controls due to shortfalls in 
oversight or resource constraints could lead to impro-
prieties and undetected errors that could result in the 
disallowance of cost recovery, noncompliant disclosure 
and reporting or incorrect payment processing. The 
consequences of these events could have a material 
adverse effect on our results of operations, financial 
condition and cash flows.

Accounting Standards

Our Consolidated Financial Statements are prepared 
in accordance with accounting principles generally 
accepted in the United States of America. The SEC, 
FASB or other authoritative bodies or governmental 
entities may issue new pronouncements or new inter-
pretations of existing accounting standards that may 
require us to change our accounting policies. These 
changes are beyond our control, can be difficult to 
predict and could materially impact how we report 
our results of operations, financial condition and cash 
flows. We could be required to apply a new or revised 
standard retroactively, which could adversely affect 
our financial position. In addition, in preparing our 
Consolidated Financial Statements, management is 
required to make estimates and assumptions. Actual 
results could differ significantly from those estimates. 
The SEC has issued a roadmap for the transition 
by U.S. public companies to the use of International 
Financial Reporting Standards (IFRS) promulgated by 
the International Accounting Standards Board. Under 
the SEC’s proposed roadmap, we could be required to 
prepare financial statements in accordance with IFRS 
in 2014. The SEC expects to make a determination in 
2011 regarding the mandatory adoption of IFRS. We 
are currently assessing the impact that this potential 
change would have on our Consolidated Financial 
Statements and we will continue to monitor the devel-
opment of the potential implementation of IFRS.

Qualified and Properly Motivated Workforce

One of the challenges we face is to retain a skilled, effi-
cient and cost-effective workforce while recruiting new 
talent to replace losses in knowledge and skills due to 
retirements. This undertaking could require us to make 
additional financial commitments and incur increased 
costs. If we are unable to successfully attract and 
retain an appropriately qualified workforce, our results 
of operations, financial condition and cash flows could 

be materially adversely affected. In addition, we have 
employee compensation plans that reward the per-
formance of our employees. While we seek to ensure 
that our compensation plans encourage acceptable 
levels for risk and high performance through pay mix, 
performance metrics and timing, and although we have 
policies and procedures in place to mitigate excessive 
risk-taking by employees, excessive risk-taking by  
our employees to achieve performance targets could 
result in events that could have a material adverse 
effect on our results of operations, financial condition 
and cash flows.

Collective Bargaining Agreements and  
Employee Relations

Over half of our employees are represented by a col-
lective bargaining agreement that is in effect until 
October 31, 2011. While we believe that we maintain 
a satisfactory relationship with our employees, it is 
possible that labor disruptions affecting some or all of 
our operations could occur during the period of the 
bargaining agreement or at the expiration of the col-
lective bargaining agreement before a new agreement 
is negotiated. Work stoppages by, or poor relations or 
ineffective negotiations with, our employees could have 
a material adverse effect on our results of operations, 
financial condition and cash flows.

Cyber Security and Terrorism

Man-made problems such as computer viruses, ter-
rorism, theft and sabotage, may disrupt our operations 
and harm our operating results. We operate in a highly 
regulated industry that requires the continued opera-
tion of sophisticated information technology systems 
and network infrastructure. Despite our implementation 
of security measures, all of our technology systems are 
vulnerable to disability, failures or unauthorized access 
due to hacking, viruses, acts of war or terrorism and 
other causes. If our technology systems were to fail or 
be breached and we were unable to recover in a timely 
way, we would be unable to fulfill critical business func-
tions and sensitive confidential and other data could 
be compromised, which could have a material adverse 
effect on our results of operations, financial condition 
and cash flows. In addition, our generation plants, fuel 
storage facilities, transmission and distribution facilities 
may be targets of terrorist activities that could disrupt 
our ability to produce or distribute some portion of our 
energy products. Any such disruption could result in a 
material decrease in revenues and significant addition-
al costs to repair and insure our assets, which could 
have a material adverse effect on our results of opera-
tions, financial condition and cash flows. The continued 
threat of terrorism and heightened security and military 

DPL Inc. 

31

 
action in response to this threat, or any future acts  
of terrorism, may cause further disruptions to the  
economies of the United States and other countries 
and create further uncertainties or otherwise materially 
harm our results of operations, financial condition  
and cash flows.

DPL as Holding Company

DPL is a holding company and its investments in its 
subsidiaries are its primary assets. Substantially all of 
DPL’s business is conducted by its DP&L subsidiary. 
As such, DPL’s cash flow is dependent on the operat-
ing cash flows of DP&L and its ability to pay cash to 
DPL. DP&L’s governing documents contain certain 
limitations on the ability to declare and pay dividends 
to DPL while preferred stock is outstanding. Certain 
of DP&L’s debt agreements also contain limits with 
respect to the ability of DP&L to loan or advance funds 
to DPL. In addition, DP&L is regulated by the PUCO 
that possesses broad oversight powers to ensure that 
the needs of utility customers are being met. While 
we are not currently aware of any plans to do so, the 
PUCO could attempt to impose restrictions on the 
ability of DP&L to pay cash to DPL pursuant to these 
broad powers. While we do not expect any foregoing 
restrictions to significantly affect DP&L’s ability to 
pay funds to DPL in the future, a significant limitation 
on DP&L’s ability to pay dividends or loan or advance 
funds to DPL would materially adversely affect 
DPL’s results of operations, financial condition and 
cash flows.

Item 1B Unresolved Staff Comments

Item 3 Legal Proceedings

In the normal course of business, we are subject to 
various lawsuits, actions, proceedings, claims and 
other matters asserted under laws and regulations. We 
are also from time to time involved in other reviews, 
investigations and proceedings by governmental and 
regulatory agencies regarding our business, certain of 
which may result in adverse judgments, settlements, 
fines, penalties, injunctions or other relief. We believe 
the amounts provided in our Consolidated Financial 
Statements, as prescribed by GAAP, for these matters 
are adequate in light of the probable and estimable 
contingencies. However, there can be no assurances 
that the actual amounts required to satisfy alleged 
liabilities from various legal proceedings, claims and 
other matters (including those matters noted below) 
and to comply with applicable laws and regulations will 
not exceed the amounts reflected in our Consolidated 
Financial Statements. As such, costs, if any, that may 
be incurred in excess of those amounts provided as of 
December 31, 2009, cannot be reasonably determined.
The information about the legal and other proceed-
ings contained in Item 1 – Competition and Regulation 
under the heading “Ohio Retail Rates” and in Item 8 –

As of February 10, 2010, there were 20,798 holders of record of DPL common equity, excluding individual 
participants in security position listings. The following table presents the high and low per share sales prices for 
DPL common stock as reported by the New York Stock Exchange for each quarter of 2009 and 2008:

DP&L’s common stock is held solely by DPL and, as a result, is not listed for trading on any stock exchange.

As long as DP&L preferred stock is outstanding, DP&L’s Amended Articles of Incorporation contain provisions 

restricting the payment of cash dividends on any of its common stock if, after giving effect to such dividend, the 
aggregate of all such dividends distributed subsequent to December 31, 1946 exceeds the net income of DP&L 
available for dividends on its Common Stock subsequent to December 31, 1946, plus $1.2 million. This dividend 
restriction has historically not impacted DP&L’s ability to pay cash dividends and, as of December 31, 2009, 
DP&L’s retained earnings of $640.3 million were all available for DP&L common stock dividends payable to DPL.

DPL paid regular quarterly cash dividends of $0.285 and $0.275 per share on our common stock during 2009 

and 2008, respectively. The annualized dividend rate was $1.14 per share in 2009 and $1.10 per share in 2008.

On December 9, 2009, DPL’s Board of Directors authorized a quarterly dividend rate increase of approximately 

6%, increasing the quarterly dividend per DPL common share from $0.2850 to $0.3025, effective with the next 
dividend declaration. If this dividend rate were maintained, the annualized dividend would increase from $1.14 
per share to $1.21 per share. Additional information concerning dividends paid on DPL common stock is set forth 
under Selected Quarterly Information in Item 8 – Financial Statements and Supplementary Data.

Information regarding DPL’s equity compensation plans as of December 31, 2009 is disclosed in Item 12 – 
Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters, which incor-
porates such information by reference from DPL’s proxy statement for the 2010 Annual Meeting of Shareholders.

(2) Comprises shares purchased as part of DPL’s current repurchase program and shares surrendered to DPL by employees to satisfy 
individual tax withholding obligations upon vesting of previously issued shares of restricted common stock. Shares totaling 3,508 were  
surrendered during 2009 to satisfy these individual tax withholding obligations.

(3) Average price paid per share reflects the individual trade price of repurchases under DPL’s current repurchase program as well as 
the closing price of DPL common stock on the vesting dates of the restricted shares.

(4) On October 28, 2009, the DPL Board of Directors approved, and DPL publicly announced, a Stock Repurchase Program under which 
DPL may use proceeds from the exercise of warrants to repurchase warrants or DPL common stock from time to time in the open market, 
through private transactions or otherwise. Through December 31, 2009, the amount of such proceeds available to be used under the  
Stock Repurchase Program approximated $68.3 million, of which $64.4 million was used during the quarter ended December 31, 2009 to  
purchase approximately 2.4 million shares at an average per share price of $26.96. At December 31, 2009, the amount still available that  
could be used to repurchase stock under the Stock Repurchase Program is approximately $3.9 million but could be higher if additional  
warrants are exercised for cash in the future. The Stock Repurchase Program will run through June 30, 2012, which is approximately three  
months after the end of the warrant exercise period.

(a) In the fourth quarter of 2006, DPL entered into agreements to sell two of its peaking facilities resulting in a $44.2 million ($71 million pre-tax) 
impairment charge. The sale was finalized in April 2007. During 2006, DPL recorded a $37.3 million ($61.2 million pre-tax) charge for early 
redemption of debt. DP&L recorded a $2.5 million ($4.1 million pre-tax) charge for early redemption of debt in 2006. In May 2007, DPL settled 
the litigation with former executives resulting in a $19.7 million ($31 million pre-tax) gain. In April 2007, DPL also recouped legal costs associated 
with the litigation with the former executives from one of its insurers resulting in a $9.2 million ($14.5 million pre-tax) gain. In 2008, DPL sold 
coal and excess emission allowances to various counterparties, realizing net gains of $58.2 million ($83.4 million pre-tax) and $24.3 million  
($34.8 million pre-tax), respectively. Also, in June 2008, DPL entered into a $42 million tax settlement with ODT resulting in a recorded income 
tax benefit of $8.5 million.

(b) On February 13, 2005, DPL’s subsidiaries, MVE, Inc. (MVE) and MVIC, entered into an agreement to sell their respective interest in forty-six 
private equity funds. MVE and MVIC completed the sale of forty-three funds and a portion of another during 2005. The ownership interests to  
the remaining two funds and a portion of the third fund were transferred in 2006 and 2007, at which time DPL recognized previously deferred gains.

Business Overview 

DPL is a regional electric energy and utility company 
and through its principal subsidiary DP&L, is primarily 
engaged in the generation, transmission and distribu-
tion of electricity in West Central Ohio. DPL and DP&L 
strive to achieve disciplined growth in energy margins 
while limiting volatility in both cash flows and earnings 
and to achieve stable, long-term growth through effi-
cient operations and strong customer and regulatory 
relations. More specifically, DPL and DP&L’s strategy is 
to match energy supply with load or customer demand, 
maximizing profits while effectively managing exposure 
to movements in energy and fuel prices and utilizing 
the transmission and distribution assets that transfer 
electricity at the most efficient cost while maintaining 
the highest level of customer service and reliability.

We operate and manage generation assets and 

are exposed to a number of risks. These risks include 
but are not limited to electricity wholesale price risk, 
fuel supply and price risk and power plant perfor-
mance. We attempt to manage these risks through  
various means. For instance, we operate a portfolio  
of wholly-owned and jointly-owned generation assets  
that is diversified as to coal source, cost structure  
and operating characteristics. We are focused on the 
operating efficiency of these power plants and main-

36  DPL Inc.

taining their availability.

We operate and manage transmission and dis-

tribution assets in a rate-regulated environment. 
Accordingly, this subjects us to regulatory risk in terms 
of the costs that we may recover and the investment 
returns that we may collect in customer rates. We are 
focused on delivering electricity and maintaining high 
standards of customer service and reliability in a cost-
effective manner. 

As we look forward, there are a number of issues 

that we believe may have a significant impact on  
our business and operations described above. The  
following issues mentioned below are not meant  
to be exhaustive but to provide insight to matters that 
have or are likely to have an effect on our industry  
and business:

Regulatory Environment

n Emissions – Climate Change Legislation

There is a growing concern nationally and internation-
ally about global climate change and the contribution 
of emissions of GHGs, including most significantly, 
CO2. This concern has led to increased interest in leg-
islation at the federal level, actions at the state level as 
well as litigation relating to GHG emissions. In 2007, a 
U.S. Supreme Court decision upheld that the USEPA 
has the authority to regulate CO2 emissions from motor 
vehicles under the CAA. In April 2009, the USEPA 
issued a proposed endangerment finding under the 
CAA, which was finalized and published December 
15, 2009. The proposed finding determined that CO2 
and other GHGs from motor vehicles threaten the 
health and welfare of future generations by contribut-
ing to climate change. It is anticipated that this ruling 
will lead to the regulation of CO2 and other GHGs from 
electric generating units and other stationary sources 
of these emissions. In June 2009, the U.S. House of 
Representatives passed H.R. 2454, the American 
Clean Energy and Security Act (ACES). This proposed 
legislation targets a reduction in the emission of GHGs 
from large sources by 80% in 2050 through an econo-
my-wide cap and trade program. ACES also includes 
energy efficiency and renewable energy initiatives. 
Increased pressure for CO2 emissions reduction is also 
coming from investor organizations and the interna-
tional community. Environmental advocacy groups are 
also focusing considerable attention on CO2 emissions 
from power generation facilities and their potential role 
in climate change. Approximately 99% of the energy 
we produce is generated by coal share of CO2 emis-
sions at generating stations we own and co-own is 

approximately 16 million tons annually. If legislation or 
regulations are passed at the federal or state levels 
that impose mandatory reductions of CO2 and 
other GHGs on generation facilities, the cost to DPL 
and DP&L of such reductions could be material.

n SB 221 Requirements

SB 221 and the implementation rules contain targets 
relating to advanced energy portfolio standards, 
renewable energy, demand reduction and energy effi-
ciency standards. The standards require that, by the 
year 2025, 25% of the total number of kWh of electric-
ity sold by the utility to retail electric consumers must 
come from alternative energy resources, which include 
“advanced energy resources” such as distributed gen-
eration, clean coal, advanced nuclear, energy efficien-
cy and fuel cell technology; and “renewable energy 
resources” such as solar, hydro, wind, geothermal and 
biomass. At least half of the 25% must be generated 
from renewable energy resources, including 0.5% from 
solar energy. The renewable energy portfolio, energy 
efficiency and demand reduction standards began 
in 2009 with increases in required percentages each 
year. The annual targets for energy efficiency and peak 
demand reductions began in 2009 with annual increas-
es. Energy efficiency programs are to save 22.3% by 
2025 and peak demand reductions are expected to 
reach 7.75% by 2018 compared to a baseline energy 
usage. If any targets are not met, compliance penalties 
will apply, unless the PUCO makes certain findings that 
would excuse performance. 

SB 221 also contains provisions for determining 
whether an electric utility has significantly excessive 
earnings. On September 9, 2009, the PUCO issued 
an entry establishing a significantly excessive earn-
ings test (SEET) proceeding. A workshop was held at 
the Commission offices on October 5, 2009 to allow 
interested parties to present concerns and discuss 
issues related to the methodology. On November 18, 
2009 the PUCO Staff issued its recommendations to 
the Commission. Staff recommendations provided that 
off-system or wholesale sales should be included in 
the calculation, and that some threshold should be 
established based on a group of comparable compa-
nies that would determine if the utility had significantly 
excessive earnings in a given year. DP&L filed its com-
ments and reply comments along with other interested 
parties. Although DP&L’s Stipulation provides that the 
SEET does not apply to DP&L until 2013 based on 
2012 earnings results, DP&L is actively participating 
in this proceeding.

n CAIR decision by the U.S. Court of Appeals for the 
District of Columbia Circuit

On July 11, 2008, the United States Court of Appeals 
for the District of Columbia Circuit issued a decision 
that vacated the USEPA CAIR and its associated 
Federal Implementation Plan. This decision remanded 
these issues back to the USEPA. The USEPA issued 
CAIR on March 10, 2005 to regulate certain upwind 
states with respect to fine particulate matter and ozone. 
CAIR created interstate trading programs for annual 
NOx emission allowances and made modifications to 
an existing trading program for SO2 that were to take 
effect in 2010. The court’s decision, in part, invalidated 
the new NOx annual emission allowance trading pro-
gram and the modifications to the SO2 emission trad-
ing program, and created uncertainty regarding future 
NOx and SO2 emission reduction requirements and 
their timing. On December 23, 2008, the court reversed 
part of its decision that vacated CAIR. Thus, CAIR cur-
rently remains in effect, but the USEPA remains subject 
to the court’s order to revise the program. In January 
2010, the Court ordered the USEPA to file a response 
to a Petition for Mandamus filed by parties in the origi-
nal case who are now seeking a Court order to require 
the USEPA to issue new regulations by March 1, 2010. 
We cannot at this time predict the timing or the out-
come of any new regulations in relation to CAIR. CAIR 
has and will continue to have a material effect on our 
operations.

In the fourth quarter of 2007, DP&L began a pro-
gram for selling excess emission allowances, including 
annual NOx emission allowances and SO2 emission 
allowances that were the subject of CAIR trading pro-
grams. In subsequent quarters, DP&L recognized 
gains from the sale of excess emission allowances to 
third parties. The court’s CAIR decision has affected 
the trading market for excess allowances and impact-
ed DP&L’s program for selling additional excess allow-
ances. The overall impact of the court’s decision, and 
of the actions the USEPA or others will take in response 
to this decision, on DPL and DP&L is not fully known 
at this time and could have an adverse effect on us. 
In January 2009, we resumed selling excess emission 
allowances due to the revival of the trading market.

Competition and PJM Pricing

n RPM Capacity Auction Price

The PJM RPM base residual auction for the 2012/2013 
period cleared at a per megawatt price of $16/day for 
our RTO area. Prior to this auction, the per megawatt 
price for the 2011/2012 period was $110/day. Future 

RPM auction results will be dependent not only on the 
overall supply and demand of generation and load, 
but may also be impacted by congestion as well as 
PJM’s business rules relating to bidding for Demand 
Response and Energy Efficiency resources in the RPM 
auctions. We cannot predict the outcome of future 
auctions but if the current auction price is sustained, 
our future results of operations, financial condition and 
cash flows could be adversely impacted. 

n Ohio Competitive Considerations and Proceedings

Overall power market prices, as well as government 
aggregation initiatives, could lead to the entrance of 
competitors in our marketplace, affecting our results 
of operations, financial condition or cash flows. During 
the year ended December 31, 2009, two additional 
unaffiliated marketers registered as CRES providers in 
DP&L’s service territory, bringing to six the total num-
ber of unaffiliated CRES providers in DP&L’s service 
territory. While there has been some customer switch-
ing associated with unaffiliated marketers, it repre-
sented less than 0.11% of sales in 2009. DPLER, an 
affiliated company, is also a registered CRES provider 
and accounted for 99% of the total kWh supplied by 
CRES providers within DP&L’s service territory in 2009. 
During the first quarter of 2010, DPLER will begin pro-
viding CRES services to business customers in Ohio 
who are not in DP&L’s service territory. At this time, 
we do not expect the incremental costs and revenues 
to have a material impact on our results of operations, 
financial position or cash flows. We currently cannot 
determine the extent to which customer switching to 
unaffiliated CRES providers will occur in the future 
and the impact this will have on our operations. In 
2003-2004, several communities in DP&L’s service 
area passed ordinances allowing the communities to 
become government aggregators for the purpose of 
offering alternative electric generation supplies to their 
citizens. To date, none of these communities have 
aggregated their generation load.

Fuel and Related Costs

n Fuel and Commodity Prices

During 2009 and 2008, the coal market experienced 
significant price volatility. We are now in a global 
market for coal in which our domestic price is increas-
ingly affected by international supply disruptions and 
demand balance. Coal exports from the U.S. have 
increased significantly in recent years. In addition, 
domestic issues like government-imposed direct costs 
and permitting issues are affecting mining costs and 

38  DPL Inc.

supply availability. Our approach is to hedge the fuel 
costs for our anticipated electric sales. For the year 
ending December 31, 2010, we have hedged our coal 
requirements to meet our committed sales. We may not 
be able to hedge the entire exposure of our operations 
from commodity price volatility. To the extent our sup-
pliers do not meet their contractual commitments or 
we are not hedged against price volatility, our results 
of operations, financial position or cash flows could 
be materially affected. Beginning in January 2010, the 
Ohio retail jurisdictional share of fuel price changes will 
be reflected in the operation of the fuel rider, subject to 
PUCO review.

n Sales of Coal and Excess Emission Allowances

During 2009, DP&L sold coal and excess emission 
allowances to various counterparties realizing total net 
gains of $56.3 million and $5.0 million, respectively. 
These gains are recorded as a component of DP&L’s 
fuel costs and reflected in operating income. Coal 
sales are impacted by a range of factors but can be 
largely attributed to the following: variation in power 
demand, the market price of power compared to the 
cost to produce power, as well as optimization oppor-
tunities in the coal market. Sales of excess emission 
allowances are impacted, among other factors, by: 
general economic conditions; fluctuations in market 
demand and pricing; availability of excess inventory 
available for sale; and changes to the regulatory envi-
ronment in which we operate. The combined impact 
of these factors on our ability to sell coal and emission 
allowances in 2010 and beyond is not fully known at 
this time and could materially impact the amount of 
gains that will be recognized in the future. In addition, 
beginning in January 2010 as part of the operation of 
the fuel rider, the Ohio retail jurisdictional share of the 
emission gains and a portion of the Ohio jurisdictional 
share of the coal gains will be used to reduce the over-
all rate charged to customers.

Financial Overview 

The following financial overview relates to DPL, which 
includes its principal subsidiary DP&L. The results of 
operations for both DPL and DP&L are separately dis-
cussed in more detail following this financial overview.
For the year ended December 31, 2009, Net 

income for DPL was $229.1 million, or $2.01 per share, 
compared to Net income of $244.5 million, or $2.12 per 
share, for the same period in 2008. All EPS amounts 
are on a diluted share basis. The decrease in net 
income compared to the prior year was primarily due 
to the following:

n a decrease in retail sales volume due to the impacts 
of the economic slowdown and milder weather through-
out the year,

n a decrease in wholesale power sales prices,

n a decrease in gains recognized from the sale of coal,

n a decrease in gains recognized from the sale of 
excess emission allowances,

n an increase in the cost of fuel due to the increased 
volume of generation by our power plants and higher 
average fuel costs, particularly for coal, and

n an increase in pension and employee benefit 
related costs.

Partially offsetting these items were:

n an increase in retail rates primarily as a result of 
an increase in the EIR and the implementation of the 
TCRR, RPM and Energy Efficiency riders,

n an improvement in generating plant performance 
which resulted in an increase in wholesale sales  
volume and a decrease in purchased power volumes,

n a decrease in power purchase prices and

n a net reduction in interest costs primarily as a result 
of certain outstanding debt redemptions.

Retail customers, especially residential and commercial 
customers, consume more electricity on warmer and 
colder days. Therefore, DPL’s retail sales volume is 
impacted by the number of heating and cooling degree 
days occurring during a year. Since DPL plans to uti-
lize its internal generating capacity to supply its retail 
customers’ needs first, increases in retail demand may 
decrease the volume of internal generation available to 
be sold in the wholesale market and vice versa.

The wholesale market covers a multi-state area 
and settles on an hourly basis throughout the year. 
Factors impacting DPL’s wholesale sales volume each 
hour of the year include wholesale market prices; 
DPL’s retail demand; retail demand elsewhere through-
out the entire wholesale market area; DPL and non-
DPL plants’ availability to sell into the wholesale market 
and weather conditions across the multi-state region. 
DPL’s plan is to make wholesale sales when market 
prices allow for the economic operation of its genera-
tion facilities not being utilized to meet its retail demand 
or when margin opportunities exist between the whole-
sale sales and power purchase prices.

For the year ended December 31, 2009, Revenues 
decreased $12.7 million, or 1%, to $1,588.9 million  
from $1,601.6 million in the prior year. This decrease 
was primarily the result of lower retail sales volume  
as well as decreased wholesale average prices, par-
tially offset by higher average retail rates, increased 
wholesale sales volume and an increase in RTO 
capacity and other revenues. The revenue components 
for the year ended December 31, 2009 are further  
discussed below: 

n Retail revenues increased $5.7 million resulting 
primarily from an 11% increase in average retail rates 

40  DPL Inc.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
due largely to the incremental effect of the recovery 
of costs under the third phase of the EIR combined 
with the implementation of the TCRR, RPM, Energy 
Efficiency and Alternative Energy riders, partially offset 
by a 9% decrease in sales volume driven largely by the 
effects of the economic recession and milder weather 
conditions. The milder weather conditions saw heating 
and cooling degree days decrease by 4% and 14% 
to 5,561 days and 734 days, respectively. As a result, 
retail revenues had a favorable $119.6 million price 
variance and an unfavorable $113.5 million sales  
volume variance. 

n Wholesale revenues decreased $27.4 million primar-
ily as a result of a 42% decrease in wholesale average 
prices partially offset by a 40% increase in sales  
volume, resulting in an unfavorable $87.0 million whole-
sale price variance and a favorable $59.6 million sales 
volume variance. 

n RTO capacity and other revenues, consisting pri-
marily of compensation for use of DPL’s transmission 
assets, regulation services, reactive supply and operat-
ing reserves as well as capacity payments under the 
RPM construct, increased $9.0 million compared to 
the same period in the prior year. This increase was 
primarily the result of additional revenue of $29.4 mil-
lion that was realized from the PJM capacity auction, 
partially offset by a decrease in PJM transmission and 
congestion revenues of $21.0 million. Beginning June 
1, 2009 when the TCRR and RPM rate riders became 
effective, the Ohio retail jurisdiction share of this 
change had no impact on net income.

For the year ended December 31, 2008, Revenues 
increased $85.9 million, or 6%, to $1,601.6 million from 
$1,515.7 million in the prior year. This increase was 
primarily the result of higher average rates for retail and 
wholesale sales as well as an increase in RTO capacity 
and other revenues, partially offset by lower retail and 
wholesale sales volumes. The revenue components 
for the year ended December 31, 2008 are further dis-
cussed below:

n Retail revenues increased $17.1 million resulting 
primarily from a 4% increase in average retail rates 
due largely to the second phase of the EIR, par-
tially offset by a 2% decrease in sales volume. The 
decrease in retail sales volume was primarily a result 
of milder weather which caused cooling degree days 
to decrease by 26% to 853 days, combined with a 6% 
decrease in the volume of sales to industrial custom-
ers. The lower sales volumes to industrial customers 
were driven largely by the downturn in the economy 
which severely affected the automotive and other relat-
ed industries in the region resulting in plant closures 

and reduced production. These decreases were par-
tially offset by a 9% increase in heating degree days.

n Wholesale revenues decreased $30.4 million primar-
ily as a result of a 33% decrease in sales volume due 
largely to unplanned outages, partially offset by a 25% 
increase in wholesale average rates, resulting in an 
unfavorable $60.2 million sales volume variance and a 
favorable $29.8 million wholesale price variance. 

n RTO capacity and other revenues, consisting pri-
marily of compensation for use of DPL’s transmission 
assets, regulation services, reactive supply and operat-
ing reserves as well as capacity payments under  
the RPM construct, increased $99.2 million compared 
to the prior year. This increase primarily resulted from 
additional income realized from the PJM capacity  
auction and increased PJM transmission and conges-
tion revenues.

DPL – Cost of Revenues

For the year ended December 31, 2009:

n Fuel costs, which include coal (net of gains on 
sales), gas, oil and emission allowances (net of gains 
on sales), increased $87.4 million, or 36%, compared 
to 2008, primarily due to the impact of lower gains 
realized from the sales of coal and excess emission 
allowances combined with a 7% increase in the usage 
of fuel due mainly to the improved performance of our 
generating facilities. In 2009, DP&L realized $56.3 
million and $5.0 million in gains from the sales of coal 
and excess emission allowances, respectively, com-
pared to $83.4 million and $34.8 million, respectively, 
during 2008. Also contributing to the increase in fuel 
costs was a 2% increase in the average cost of fuel 
consumed per kilowatt-hour largely resulting from  
higher market prices of coal combined with outages  
at lower-cost units. 

n Purchased power decreased $117.2 million com-
pared to 2008. The net decrease in purchased power 
was due in part to lower volumes of purchased power 
and lower average market rates of $72.3 million and 
$29.5 million, respectively. The improved performance 
of our generating facilities, as mentioned in the preced-
ing paragraph, resulted in increased generation output 
and a reduced demand for higher-cost purchased 
power. Also contributing to the decrease in purchased 
power were lower costs relating to other RTO charges 
as well as the net deferral during 2009 of costs relat-
ing to DP&L’s transmission, capacity and other PJM-
related charges which were incurred as a member of 
PJM. This deferral is discussed in greater detail in  
Note 3 of Notes to Consolidated Financial Statements. 

DPL Inc.

These decreases were partially offset by increased 
RTO capacity charges. We purchase power to satisfy 
retail sales volume when generating facilities are not 
available due to planned and unanticipated outages,  
or when market prices are below the marginal costs 
associated with our generating facilities.

For the year ended December 31, 2008:

n Fuel costs, which include coal (net of gains on 
sales), gas, oil, and emission allowances (net of gains 
on sales), decreased $85.2 million, or 26%, compared 
to 2007, primarily due to increases in net gains of 
$33.6 million from the sale of DP&L’s excess emis-
sion allowances and $82.8 million realized from the 
sale of DP&L’s coal combined with a decrease in the 
usage of fuel due mainly to a 6% decrease in genera-
tion output largely attributable to unplanned outages. 
These decreases were partially offset by increased fuel 
prices. The successful installation of FGD equipment at 
Miami Fort, Killen and J.M. Stuart stations has allowed 
us the ability to burn coal with a wide range of sulfur 
content and, accordingly, we purchase and sell coal as 
we seek to achieve optimum levels of production effi-
ciency. Gains or losses from sales of coal and emission 
allowances are recorded as components of fuel costs.

n Purchased power costs increased $90.2 million, or 
31%, compared to 2007. The increase in purchased 
power primarily results from a $15.3 million increase 
relating to higher average market rates and a $98.4 
million increase in RTO capacity and other RTO 
charges, partially offset by a $23.5 million decrease 
relating to lower volumes of purchased power. We 
purchase power to satisfy retail sales volume when 
generating facilities are not available due to planned 
and unplanned outages, or when market prices are 
below the marginal costs associated with our generat-
ing facilities.

(1) There is a corresponding increase in revenues associated  
with these programs resulting in no impact to net income.

During the year ended December 31, 2009, Operation 
and maintenance expense increased $24.0 million,  
or 8%, compared to 2008. This variance was primarily 
the result of:

n higher pension costs due largely to a decline in the 
values of pension plan assets from 2008 and increased 
benefit costs, 

n increases in assistance for low-income retail custom-
ers which is funded by the USF revenue rate rider,

n expenses related to new energy efficiency programs 
put in place for our customers during 2009, 

n increased deferred compensation costs, 

n increases in employee benefit expense funded by 
the ESOP and

n increased health insurance costs that were partially 
related to higher disability reserves.

These increases were partially offset by:

n lower amortization of regulatory assets related to the 
2004/2005 deferred storm costs and PJM administra-
tive fees in 2009 as these deferred costs were fully 
recovered through rates during 2008 and in the first 
quarter of 2009, respectively, and

n decreases in expenses for generating facilities 
largely due to unplanned outages in 2008 at lower-cost 
production units resulting in higher costs in that year. 
These decreases were partially offset by increased 
maintenance expenses associated with unplanned out-
ages at jointly-owned production units during 2009.

or less than 1%, as compared to 2007. This variance 
was primarily due to: 

n a decrease in legal costs due largely to the litigation 
settlement with three of our former executives in  
May 2007, 

42  DPL Inc.

 
 
 
 
 
 
 
 
 
 
 
 
n a decrease in deferred compensation costs associ-
ated to a large degree with deferred compensation 
liabilities for the three former executives, 

n a decrease in employee compensation expense 
associated with the ESOP due mainly to the additional 
shares that were released from the ESOP in 2007 and

n lower pension costs primarily due to the plan 
funding made in November 2007.

These decreases were partially offset by:

n the 2007 insurance settlement which reimbursed 
us for legal fees relating to the litigation with three  
former executives, 

n an increase in operating expenses largely due to 
the operation of FGD and SCR equipment and related 
gypsum disposal, 

n the gain on sale of the corporate aircraft realized 
in 2007 and 

n an increase in turbine maintenance costs incurred 
due to an unplanned outage at a jointly-owned  
production unit.

DPL – Depreciation and Amortization

During the year ended December 31, 2009, 
Depreciation and amortization expense increased $7.8 
million, or 6%, compared to 2008 primarily as a result 
of higher asset balances at the generating stations. 
These higher balances were due largely to the comple-
tion of the FGD projects during 2008.

During the year ended December 31, 2008, 

Depreciation and amortization expense increased $2.9 
million, or 2%, as compared to 2007. This increase was 
primarily a result of higher plant balances due largely 
to the installation of the FGD equipment, partially offset 
by the impact of lower depreciation rates for generation 
property which were put into effect on August 1, 2007.

DPL – General Taxes

During the year ended December 31, 2009, General 
taxes decreased $7.4 million, or 6%, compared to 2008 
primarily due to lower property tax accruals in 2009 
compared to 2008 and lower kWh excise taxes result-
ing from lower retail sales volumes.

led to higher assessed property values, combined with 
increased tax rates.

DPL – Investment Income (Loss)

During the year ended December 31, 2009, Investment 
income (loss) decreased $4.2 million, or 117%, as  
compared to 2008 primarily as a result of lower cash 
and short-term investment balances combined with 
overall lower market yields on investments in 2009. 
In addition, we also recorded a $1.4 million expense 
during 2009 relating to a loss incurred by DPL Capital 
Trust II, a nonconsolidated wholly-owned subsidiary.
During the year ended December 31, 2008, 
Investment income (loss) decreased $7.7 million, or 
68%, as compared to 2007. This decrease was primar-
ily the result of: 

n $3.2 million of gains realized in 2007 from the sale 
of financial assets held in DP&L’s Master Trust Plan 
for deferred compensation which were used for the 
settlement payment to three former executives and

n lower cash and short-term investment balances 
combined with overall lower market yields on invest-
ments in 2008 compared to 2007.

DPL – Net Gain on Settlement of  
Executive Litigation

On May 21, 2007, we settled litigation with three former 
executives. In exchange for our payment of $25 million, 
the three former executives relinquished and dismissed 
all of their claims, including those related to deferred 
compensation, RSUs, MVE incentives, stock options 
and legal fees. As a result of this settlement, during 
2007, DPL realized a net pre-tax gain in continuing 
operations of approximately $31.0 million. See Note 17 
of Notes to Consolidated Financial Statements.

DPL – Interest Expense 

During the year ended December 31, 2009, Interest 
expense decreased $7.7 million, or 8%, compared to 
2008 primarily due to: 

n a $12.8 million reduction in Interest expense due 
to the redemption of DPL’s $175 million 8.00% Senior 
Notes and the $100 million 6.25% Senior Notes in 
March 2009 and May 2008, respectively, 

During the year ended December 31, 2008, 

General taxes increased $13.7 million, or 12%, as com-
pared to 2007, primarily as a result of higher property 
taxes due mainly to capital improvements which have 

n a $1.6 million write-off in 2008 of unamortized debt 
issuance costs relating to DP&L’s $90 million variable 
rate pollution control bonds following their repurchase 
from the bondholders in April 2008 and

DPL Inc. 

43

 
n $2.0 million of deferred interest carrying costs on 
regulatory assets primarily associated with the 2008 
incremental storm costs and the riders for RPM and 
TCRR. These regulatory assets are further discussed in 
Note 3 of Notes to Consolidated Financial Statements.

The above decreases were partially offset by $6.4 mil-
lion of lower capitalized interest in 2009 compared to 
2008, due largely to the completion of the FGD projects 
at our DP&L and partner-operated generating stations, 
as well as a $3.7 million premium paid on the early 
redemption of a portion of DPL’s Note to DPL Capital 
Trust II which is due 2031. In December 2009, DPL 
redeemed $52.4 million of this $195 million 8.125% 
note. This redemption is further discussed in Note 7  
of Notes to Consolidated Financial Statements.

During the year ended December 31, 2008, 
Interest expense increased $9.7 million, or 12%, as 
compared to 2007 primarily due to: 

n $12.9 million of lower capitalized interest due to the 
completion of the FGD projects at Miami Fort, Killen 
and J.M. Stuart stations, 

n the write-off of unamortized debt issuance costs 
amounting to $1.6 million relating to pollution control 
bonds following their repurchase from the bondholders 
in April 2008 and

n $0.9 million of additional interest expense associated 
with DP&L’s $90 million variable rate pollution control 
bonds issued November 15, 2007 and repurchased  
in April 2008.

These increases were partially offset by a $7.0 million 
interest expense reduction due to the redemption  
of the $225 million 8.25% Senior Notes in March 2007 
and the $100 million 6.25% Senior Notes in May 2008.

DPL – Other Income (Deductions) 

During the year ended December 31, 2009, there 
were no material fluctuations in the balances of Other 
income (deductions). 

During the year ended December 31, 2008, other 
deductions of $1.0 million changed from other income 
of $2.9 million recorded in 2007. The change from 
other income to other deductions primarily resulted 
from the recognition in 2007 of a $2.1 million deferred 
credit related to a litigation settlement (which was not 
part of the executive litigation settlement).

DPL Inc. – Income Tax Expense 

For the year ended December 31, 2009, Income tax 
expense increased $9.6 million, or 9%, compared to 

44  DPL Inc.

2008, due to estimate to actual adjustments of 2008 
taxes related to the Internal Revenue Code Section 199 
deduction, adjustments to deferred tax liabilities and 
a 2008 settlement relating to the Ohio Franchise Tax. 
These increases were partially offset by a decrease 
in pre-tax book earnings, estimate to actual adjust-
ments of 2008 state tax liabilities, adjustments to our 
current tax receivables and the phase-out of the Ohio 
Franchise Tax.

During 2008, Income tax expense decreased 
$19.6 million, or 16%, as compared to 2007, primarily 
due to a decrease in the effective tax rate reflecting  
the phase-out of the Ohio Franchise Tax and the  
2008 settlement of the Ohio Franchise Tax issue which 
resulted in a recorded tax benefit of $8.5 million.

DP&L – Revenues 

Retail customers, especially residential and commercial 
customers, consume more electricity on warmer and 
colder days. Therefore, DP&L’s retail sales volume is 
impacted by the number of heating and cooling degree 
days occurring during a year. Since DP&L plans to 
utilize its internal generating capacity to supply its retail 
customers’ needs first, increases in retail demand may 
decrease the volume of internal generation available to 
be sold in the wholesale market and vice versa.

The wholesale market covers a multi-state area 
and settles on an hourly basis throughout the year. 
Factors impacting DP&L’s wholesale sales volume 
each hour of the year include wholesale market pric-
es; DP&L’s retail demand, retail demand elsewhere 
throughout the entire wholesale market area; DP&L 
and non-DP&L plants’ availability to sell into the 
wholesale market and weather conditions across the 
multi-state region. DP&L’s plan is to make wholesale 
sales when market prices allow for the economic 
operation of its generation facilities that are not being 
utilized to meet its retail demand or when margin 
opportunities exist between the wholesale sales and 
power purchase prices.

For the year ended December 31, 2009, Revenues 
decreased $22.5 million, or 1%, to $1,550.4 million from 
$1,572.9 million in the prior year. This decrease was 
primarily the result of lower wholesale average prices 
and lower retail sales volume, partially offset by higher 
average retail rates and increased wholesale sales 
volume. The revenue components for the year ended 
December 31, 2009 are further discussed below: 

n Retail revenues increased $91.9 million resulting 
primarily from a 20% increase in average retail rates 
due largely to the incremental effect of the third phase 

of the EIR and the implementation of the TCRR, RPM, 
Energy Efficiency and Alternative Energy rate riders, 
partially offset by a 9% decrease in retail sales volume 
driven largely by the effects of the economic recession 
and milder weather conditions. The milder weather 
conditions saw heating and cooling degree days 
decrease by 4% and 14% to 5,561 days and 734 days, 
respectively. As a result, retail revenues had a favor-
able $191.7 million price variance and an unfavorable 
$99.7 million sales volume variance. 

n Wholesale revenues decreased $111.6 million 
primarily as a result of a 56% decrease in wholesale 
average prices, partially offset by a 41% increase in 
sales volume, resulting in an unfavorable $230.5 million 
wholesale price variance and a favorable $118.9  
million sales volume variance. 

n RTO capacity and other revenues, consisting primar-
ily of compensation for use of DP&L’s transmission 
assets, regulation services, reactive supply and operat-
ing reserves, as well as capacity payments under  
the RPM construct, decreased $2.8 million compared 
to the prior year. This decrease primarily resulted  
from $22.2 million of lower transmission and congestion 
revenues, partially offset by additional revenue of  
$19.4 million that was realized from the PJM capacity 
auction. Beginning June 1, 2009 when the TCRR and 
RPM rate deferral riders became effective, the Ohio 
retail jurisdiction share of this change had no impact  
on Net income.

For the year ended December 31, 2008, Revenues 
increased $65.5 million, or 4%, to $1,572.9 million from 
$1,507.4 million in the same period of the prior year. 
This increase was primarily the result of higher aver-
age rates for retail and wholesale sales, as well as an 
increase in RTO capacity and other revenues, partially 
offset by lower retail and wholesale sales volumes. The 
revenue components for the year ended December 31, 
2008 are further discussed below:

n Retail revenues increased $17.9 million resulting 
primarily from a 4% increase in average retail rates 
due largely to the second phase of the EIR, par-
tially offset by a 2% decrease in sales volume. The 
decrease in retail sales volume was primarily a result 
of milder weather which caused cooling degree days 
to decrease by 26% to 853 days, combined with a 6% 
decrease in the volume of sales to industrial custom-
ers. The lower sales volumes to industrial customers 
were driven largely by the downturn in the economy 
which has severely affected the automotive and  
other related industries in the region resulting in plant  
closures and reduced production. These decreases

were partially offset by a 9% increase in heating 
degree days.

n Wholesales revenues decreased $38.2 million primar-
ily as a result of a 35% decrease in sales volume due 
largely to unplanned outages, partially offset by a 37% 
increase in wholesale average rates, resulting in an 
unfavorable $117.4 million sales volume variance and a 
favorable $79.2 million wholesale price variance.

n RTO capacity and other revenues, consisting primar-
ily of compensation for use of DP&L’s transmission 
assets, regulation services, reactive supply and operat-
ing reserves, as well as capacity payments under  
the RPM construct, increased $85.8 million compared 
to the prior year. This increase primarily resulted  
from additional income realized from the PJM capacity 
auction and increased PJM transmission and conges-
tion revenues.

DP&L – Cost of Revenues

For the year ended December 31, 2009:

n Fuel costs, which include coal (net of gains on 
sales), gas, oil and emission allowances (net of gains 
on sales), increased $92.2 million, or 40%, compared 
to 2008, primarily due to the impact of lower gains 
realized from the sales of coal and excess emission 
allowances combined with a 7% increase in the usage 
of fuel due mainly to the improved performance of our 
generating facilities. In 2009, DP&L realized $56.3 mil-
lion and $5.0 million in gains from the sales of coal and 
excess emission allowances, respectively, compared 
to $83.4 million and $34.8 million, respectively, during 
2008. Also contributing to the increase in fuel costs 
was a 3% increase in the average cost of fuel con-
sumed per kilowatt-hour largely resulting from higher 
market prices of coal combined with outages at  
lower-cost units. 

n Purchased power decreased $120.7 million com-
pared to 2008. The net decrease in purchased power 
was due in part to lower volumes of purchased power 
and lower average market rates of $74.8 million and 
$30.8 million, respectively. The improved performance 
of our generating facilities, as mentioned in the preced-
ing paragraph, resulted in increased generation output 
and a reduced demand for higher-cost purchased 
power. Also contributing to the decrease in purchased 
power were lower costs relating to other RTO charges 
as well as the net deferral during 2009 of costs relat-
ing to DP&L’s transmission, capacity and other PJM-
related charges which were incurred as a member of 
PJM. This deferral is discussed in greater detail in  
Note 3 of Notes to Consolidated Financial Statements. 

These decreases were partially offset by increased 
RTO capacity charges. We purchase power to satisfy 
retail sales volume when generating facilities are not 
available due to planned and unanticipated outages,  
or when market prices are below the marginal costs 
associated with our generating facilities.

For the year ended December 31, 2008:

n Fuel costs, which include coal (net of gains on 
sales), gas, oil and emission allowances (net of gains 
on sales), decreased $84.0 million, or 27%, compared 
to 2007, primarily due to increases in net gains of 
$33.6 million from the sale of DP&L’s excess emis-
sion allowances and $82.8 million realized from the 
sale of DP&L’s coal combined with a decrease in the 
usage of fuel due mainly to a 6% decrease in genera-
tion output largely attributable to unplanned outages. 
These decreases were partially offset by increased fuel 
prices. The successful installation of FGD equipment at 
Miami Fort, Killen and J.M. Stuart stations has allowed 
us the ability to burn coal with a wide range of sulfur 
content and, accordingly, we purchase and sell coal as 
we seek to achieve optimum levels of production effi-
ciency. Gains or losses from sales of coal and emission 
allowances are recorded as components of fuel costs.

n Purchased power costs increased $79.6 million, or 
27%, compared to 2007. The increase in purchased 
power primarily results from an $11.8 million increase 
relating to higher average market rates and a $97.2 
million increase in RTO capacity and other RTO 
charges, partially offset by a $29.3 million decrease 
relating to lower volumes of purchased power. We 
purchase power to satisfy retail sales volume when 
generating facilities are not available due to planned 
and unplanned outages, or when market prices are 
below the marginal costs associated with our generat-
ing facilities.

During the year ended December 31, 2009, Operation 
and maintenance expense increased $20.4 million,  
or 7%, compared to 2008. This variance was primarily 
the result of:

n higher pension costs due largely to a decline in the 
values of pension plan assets from 2008 and increased 
benefit costs, 

n increases in assistance for low-income retail custom-
ers which is funded by the USF revenue rate rider,

n expenses related to new energy efficiency programs 
put in place for our customers during 2009, 

n increases in employee benefit expense funded by 
the ESOP and

n increased health insurance costs that were partially 
related to higher disability reserves. 

These increases are partially offset by:

n lower amortization of regulatory assets related to the 
2004/2005 deferred storm costs and PJM administra-
tive fees in 2009 as these deferred costs were fully 
recovered through rates during 2008 and in the first 
quarter of 2009, respectively, and

n decreases in expenses for generating facilities 
largely due to unplanned outages in 2008 at lower-cost 
production units resulting in higher costs in that year. 
These decreases were partially offset by increased 
maintenance expenses associated with unplanned out-
ages at jointly-owned production units during 2009.

$  (8.8)

During the year ended December 31, 2008, Operation 
and maintenance expense decreased $8.8 million, or 
3%, as compared to 2007. This variance was primarily 
due to:

n a decrease in deferred compensation costs 
associated to a large degree with deferred compen-
sation liabilities for three former executives, 

n a decrease in legal fees and 

n lower pension costs primarily due to the plan 
funding made in November 2007. 

These decreases were partially offset by: 

n an increase in operating expenses at our generating 
facilities largely due to the operation of the FGD  
and SCR equipment and related gypsum disposal, 

n an increase in turbine maintenance costs incurred 
due to an unplanned outage at a jointly-owned  
production unit and

n an increase in boiler maintenance expenses in 2008.

DP&L – Depreciation and Amortization 

During the year ended December 31, 2009, 
Depreciation and amortization expense increased $7.7 
million, or 6%, as compared to 2008 primarily as a 
result of higher asset balances at the generating sta-
tions. These higher balances were due largely to the 
completion of the FGD projects during 2008.

During the year ended December 31, 2008, 

Depreciation and amortization expense increased $3.3 
million, or 3%, as compared to 2007. This increase was 
primarily a result of higher plant balances due largely 
to the installation of FGD equipment, partially offset by 
the impact of lower depreciation rates for generation 
property which were put into effect on August 1, 2007.

DP&L – General Taxes

During the year ended December 31, 2009, General 
taxes decreased $7.4 million, or 6%, compared to 2008 
primarily due to lower property tax accruals in 2009 
compared to 2008 and lower kWh excise taxes result-
ing from lower retail sales volumes.

During the year ended December 31, 2008, 

General taxes increased $13.9 million, or 13%, as com-
pared to 2007, primarily as a result of higher property 
taxes due mainly to capital improvements which have 
led to higher assessed property values, combined with 
increased tax rates.

DP&L – Investment Income

n a decrease in employee compensation expense 
associated with the ESOP due mainly to the additional 
shares that were released from the ESOP in 2007, 

During the year ended December 31, 2009, Investment 
income (loss) decreased $4.2 million, or 60%, as  
compared to 2008 primarily as a result of lower gains 

DPL Inc. 

47

 
 
 
 
 
 
 
realized from the sale of DPL common stock from 
DP&L’s Master Trust Plan used for deferred compensa-
tion distributions as well as lower cash and short-term 
investment balances combined with overall lower  
market yields on investments in 2009. 

During the year ended December 31, 2008, 
Investment income (loss) decreased $16.7 million,  
or 70%, as compared to 2007. This decrease was  
primarily the result of:

n $14.8 million of gains realized in 2007 on the transfer 
of DPL common stock to the DP&L Retirement Income 
Plan Trust (Pension) and

n $3.2 million of gains realized in 2007 from the sale 
of financial assets held in DP&L’s Master Trust Plan for 
deferred compensation which were used for the settle-
ment payment to three former executives.

DP&L – Net Gain on Settlement of Executive Litigation

On May 21, 2007, we settled litigation with three former 
executives. In exchange for our payment of $25 million, 
the three former executives relinquished and dismissed 
all of their claims, including those related to deferred 
compensation, RSUs, MVE incentives, stock options 
and legal fees. As a result of this settlement, in 2007, 
DP&L realized a net pre-tax gain in continuing 
operations of approximately $35.3 million. See Note 17 
of Notes to Consolidated Financial Statements.

DP&L – Interest Expense 

During the year ended December 31, 2009, Interest 
expense increased $2.0 million, or 5%, as compared 
to 2008 primarily as a result of $6.4 million of lower 
capitalized interest due largely to the completion of the 
FGD projects at our own and partner-operated generat-
ing stations. This increase was partially offset by:

n a $1.6 million write-off in 2008 of unamortized debt 
issuance costs relating to DP&L’s $90 million variable 
rate pollution control bonds following their repurchase 
from the bondholders in April 2008 and

n $2.0 million of deferred interest carrying costs on reg-
ulatory assets primarily associated with the 2008 incre-
mental storm costs and the riders for RPM and TCRR. 
These Regulatory assets are further discussed in Note 
3 of Notes to Consolidated Financial Statements. 

During the year ended December 31, 2008, Interest 
expense increased $14.2 million, or 64%, as compared 
to 2007 primarily as a result of:

n $12.9 million of lower capitalized interest due to the 
completion of the FGD projects at Miami Fort, Killen, 
and J.M. Stuart stations, 

n the write-off of unamortized debt issuance costs 
amounting to $1.6 million relating to DP&L’s $90 mil-
lion variable rate pollution control bonds following their 
repurchase from the bondholders in April 2008 and

n $0.9 million of additional Interest expense associated 
with DP&L’s $90 million variable rate pollution control 
bonds issued in November 2007 and repurchased in 
April 2008.

DP&L – Other Income (Deductions)

During the year ended December 31, 2009, there 
were no material fluctuations in the balances of Other 
income (deductions). 

During the year ended December 31, 2008, Other 
deductions of $1.1 million changed from Other income 
of $2.9 million recorded in 2007. The change from 
Other income to Other deductions primarily resulted 
from the recognition in 2007 of a $2.1 million deferred 
credit related to a litigation settlement (which was not 
part of the executive litigation settlement).

DP&L – Income Tax Expense 

For the year ended December 31, 2009, Income tax 
expense increased $4.3 million, or 4%, compared  
to 2008, due to estimate to actual adjustments of 2008 
income taxes related to the Internal Revenue Code 
Section 199 deduction, adjustments to deferred tax 
liabilities and a 2008 settlement relating to the Ohio 
Franchise Tax. These increases were partially offset by 
a decrease in pre-tax book earnings, estimate to actual 
adjustments of 2008 state tax liabilities, adjustments 
to our current tax receivables and the phase-out of the 
Ohio Franchise Tax.

During 2008, Income tax expense decreased 
$22.9 million, or 16%, as compared to 2007, primarily 
due to a decrease in the effective tax rate reflecting the 
phase-out of the Ohio Franchise Tax and the 2008 set-
tlement of the Ohio Franchise Tax issue which resulted 
in a recorded tax benefit of $8.5 million.

Net Cash Provided by Operating Activities

The tariff-based revenue from our energy business continues to be the principal source of cash from operating 
activities while our primary uses of cash include payments for fuel, purchased power, operation and maintenance 
expenses, interest and taxes. Management believes that the diversified retail customer mix of residential,  
commercial and industrial classes coupled with rate relief approved by the PUCO provides us with a reasonably 
predictable gross cash flow from operations.

For the year ended December 31, 2009, Net cash provided by operating activities was primarily a result of 
Earnings from continuing operations adjusted for noncash depreciation and amortization, combined with the  
following significant transactions:

n the $201.6 million increase to Deferred income taxes primarily results from the recognition of certain tax 
benefits for 2008 and 2009 relating to a change in the tax accounting method for deductions pertaining to repairs, 
depreciation and mixed service costs. Primarily due to the recognition of these benefits during 2009, DPL 
received a net cash refund of state and federal income taxes totaling $94.6 million and, in addition, was able to  
offset $69.0 million of these benefits against income tax liabilities accrued in 2009;

n the $15.7 million of cash used to pay for transmission, capacity and other PJM-related costs incurred during 
2009, net of recoveries. These costs were recorded as a Regulatory asset in accordance with the provisions  
of GAAP relating to regulatory accounting (see Note 3 of Notes to Consolidated Financial Statements) and are 
expected to be collected from customers during future years.

n Other represents items that had a current period cash flow impact and includes changes in working capital and 
other future rights or obligations to receive or to pay cash. These items are primarily impacted by, among other  
factors, the timing of when cash payments are made for fuel, purchased power, operating costs, interest and taxes, 
and when cash is received from our utility customers and from the sales of coal and excess emission allowances.

For the year ended December 31, 2008, Net cash provided by operating activities was primarily a result of 
Earnings from continuing operations adjusted for noncash depreciation and amortization, combined with the  
following significant transactions: 

n Deferred income taxes increased by $43.1 million as a result of the acceleration of the deduction of newly 
installed FGD and SCR equipment for tax purposes, which had the effect of reducing current period income  
tax payments and increasing cash on hand,

n the $42 million cash payment made in 2008 to the ODT following a tax settlement agreement and 

n the $13.1 million of cash used to restore damage of a non-capital nature caused by the hurricane-force winds 
of September 2008 and other major 2008 storms. These costs were recorded as a Regulatory asset in accordance 
with the provisions of GAAP relating to regulatory accounting (see Note 3 of Notes to Consolidated Financial 
Statements) and are expected to be collected from customers during future years.

n Other represents items that had a current period cash flow impact and includes changes in working capital 
and other future rights or obligations to receive or to pay cash, such as regulatory assets and liabilities. 

For the year ended December 31, 2007, Net cash provided by operating activities was primarily a result of 
Earnings from continuing operations adjusted for noncash depreciation and amortization and the noncash impact 
of the net gain realized on settlement of the executive litigation. Other represents items that had a current period 
cash flow impact and includes changes in working capital and other future rights or obligations to receive or  
to pay cash, such as regulatory assets and liabilities.

For all years, the environmental-related capital expenditures relate to cash outflows incurred during the installation 
and upgrades of FGD and SCR equipment. Other plant-related asset acquisitions relate to investments in other 
generation, transmission and distribution equipment. 

For the year ended December 31, 2009, DP&L continued to see reductions in its environmental-related capital 
expenditures due to the completion of FGD and SCR projects. The expenditures in 2009 relate to the construction 
of FGD and SCR equipment at the Conesville generation station which was substantially completed and placed  
into service during the fourth quarter of 2009. DP&L also continued to make upgrades and other investments in 
other generation, transmission and distribution equipment.

For the year ended December 31, 2008, DP&L saw reduced cash outflows associated with environmental-related 
expenditures compared to 2007 due to projects relating to the installation of FGD and SCR equipment that  
had either been completed or were nearing completion. In addition, DP&L was forced to replace a portion of its 
distribution lines and equipment following the damage caused by the hurricane-force winds of September 2008 
and other 2008 storms.

For the year ended December 31, 2007, the proceeds received from asset sales relate to the sale of two  
DPLE peaker units and an aircraft previously owned by a DPL subsidiary.

For the year ended December 31, 2009, DPL redeemed long-term debt totaling $227.4 million and paid 
common stock dividends of $128.8 million. Under a stock repurchase program approved by the Board of Directors 
in October 2009 (see Note 14 of Notes to Consolidated Financial Statements), DPL repurchased approximately 2.4 
million DPL common shares for $64.4 million. In addition, DPL repurchased 8.6 million warrants for $25.2 million. 
DPL’s cash inflows during the period include $77.7 million received from the cash exercise of 3.7 million warrants 
and the withdrawal of the remaining balance of restricted funds of $14.5 million which was used primarily to fund 
the construction of FGD equipment at the Conesville generation station. DPL also received $9.0 million from option 
holders who exercised stock options due, in part, to the increase in our average stock price compared to 2008.

For the year ended December 31, 2008, DPL paid common stock dividends of $120.5 million, retired $100 
million of long-term debt and withdrew $32.5 million from restricted funds held in trust to pay for environmental-
related capital expenditures. In comparison to 2007, the lower cash withdrawals from restricted funds in  
2008 were primarily due to the timing of costs incurred relating to the installation of FGD and SCR equipment. 
In addition, the reduced cash proceeds in 2008 from the exercise of stock options were a direct result of fewer 
options exercised. 

For the year ended December 31, 2007, DPL retired $225 million of long-term debt, paid common stock 
dividends of $111.7 million, withdrew $63.2 million from restricted funds to pay for environmental-related capital 
expenditures and received $14.6 million from the exercise of stock options.

Liquidity

We expect our existing sources of liquidity to remain sufficient to meet our anticipated obligations. Our business is 
capital intensive, requiring significant resources to fund operating expenses, construction expenditures, scheduled 
debt maturities, and interest and dividend payments. For 2010 and in subsequent years, we expect to satisfy  
these requirements with a combination of cash from operations and funds from the capital markets as our internal 
liquidity needs and market conditions warrant. We also expect that the borrowing capacity under credit facilities  
will continue to be available to manage working capital requirements during those periods.

We have access to $320 million of short-term financing under two revolving credit facilities. The first facility  
for $220 million expires November 2011 and has three participating banks; the lead bank has a total commitment  
of 36% while the other two have commitments of 32% each. The second facility is a 364-day $100 million facility 
that matures April 2010. A total of six banks participate in this facility, with no bank having more than 26% of  
the total commitment. The two bank groups have no common members. We are currently evaluating the impact  
the maturity of the $100 million facility will have on our future liquidity and would expect to be able to renew or 
replace this facility as needed.

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 $590 million in capital projects for the period 2010 
through 2012, mostly through its subsidiary DP&L. 

Planned construction additions for 2010 relate primarily to new investments in and upgrades to DP&L’s power 

plant equipment and transmission and distribution systems. In addition to our capital requirements above, on 
August 4, 2009, DP&L re-filed its smart grid and advanced metering infrastructure (AMI) business cases with the 
PUCO under which it would spend approximately $270 million on capital projects during the period 2010 through 
2012. Approval from the PUCO of these cases is still pending. The re-filing at the PUCO is further discussed in 
Note 3 of Notes to Consolidated Financial Statements. 

Our ability to complete capital projects and the reliability of future service will be affected by our financial  

condition, the availability of internal funds and the reasonable cost of external funds. We expect to finance  
our construction additions with a combination of cash on hand, short-term financing, long-term debt and cash  
flows from operations.

Off-Balance Sheet Arrangements

DPL - Guarantees 

In the normal course of business, DPL enters into various agreements with its wholly-owned subsidiaries, 
DPLE and DPLER, providing financial or performance assurance to third parties. These agreements are entered 
into primarily to support or enhance the creditworthiness otherwise attributed to DPLE and DPLER on a stand- 
alone basis, thereby facilitating the extension of sufficient credit to accomplish DPLE’s and DPLER’s intended  
commercial purposes. 

At December 31, 2009, DPL had $51 million of guarantees to third parties for future financial or performance 

assurance under such agreements, on behalf of DPLE and DPLER. The guarantee arrangements entered into  
by DPL with these third parties cover all present and future obligations of DPLE and DPLER to such beneficiaries 
and are terminable at any time by DPL upon written notice to the beneficiaries. The carrying amount of obligations 
for commercial transactions covered by these guarantees and recorded in our Consolidated Balance Sheets  
was $0.6 million at December 31, 2009 and $1.6 million at December 31, 2008.

In two separate transactions in November and December 2006, DPL also agreed to be a guarantor of 

the obligations of DPLE regarding the sale in April 2007 of the Darby Electric Peaking Station to American Electric 

DPL Inc. 

53

 
 
 
 
 
Power and the sale of the Greenville Electric Peaking Station to Buckeye Electric Power, Inc. In both cases,  
DPL agreed to guarantee the obligations of DPLE over a multiple-year period as follows:

In 2009, neither DPL nor DP&L incurred any losses related to the guarantees of DPLE’s obligations and we 
believe it is remote that either DPL or DP&L would be required to perform or incur any losses in the future 
associated with any of the above guarantees of DPLE’s obligations.

DP&L – Equity Ownership Interest 

DP&L owns a 4.9% equity ownership interest in OVEC, an electric generation company. As of December 31, 2009, 
DP&L could be responsible for the repayment of 4.9%, or $54.4 million, of a $1,110 million debt obligation that 
matures in 2026. This would only happen if OVEC defaulted on its debt payments. As of December 31, 2009, we 
have no knowledge of such a default.

Contractual Obligations and Commercial Commitments

We enter into various contractual obligations and other commercial commitments that may affect the liquidity  
of our operations. At December 31, 2009, these include:

Interest payments: 
Interest payments associated with the long-term debt 
described above. The interest payments relating to  
variable-rate debt are projected using the interest rate 
prevailing at December 31, 2009.

Pension and postretirement payments: 
As of December 31, 2009, DPL, through its principal 
subsidiary DP&L, had estimated future benefit 
payments as outlined in Note 9 of Notes to 
Consolidated Financial Statements. These estimated 
future benefit payments are projected through 2019. 

Capital leases:
As of December 31, 2009, DPL, through its principal 
subsidiary DP&L, had one immaterial capital lease 
that expires in September 2010.

Operating leases: 
As of December 31, 2009, DPL, through its principal 
subsidiary DP&L, had several immaterial operating 
leases with various terms and expiration dates. 

Coal contracts: 
DPL, through its principal subsidiary DP&L, has 
entered into various long-term coal contracts to  
supply the coal requirements for the generating plants  
it operates. Some contract prices are subject to  
periodic adjustment and have features that limit price 
escalation in any given year. 

Limestone contracts:
DPL, through its principal subsidiary DP&L, has 
entered into various limestone contracts to supply  
limestone used in the operation of FGD equipment  
at its generating facilities. 

Purchase orders and other contractual obligations: 
As of December 31, 2009, DPL and DP&L had various 
other contractual obligations including non-cancelable 
contracts to purchase goods and services with various 
terms and expiration dates.

Reserve for uncertain tax positions:
Due to the uncertainty regarding the timing of future 
cash outflows associated with our unrecognized  
tax benefits of $19.3 million, we are unable to make  
a reliable estimate of the periods of cash settlement  
with the respective tax authorities and have not  
included such amounts in the contractual obligations 
table above. 

Market Risk

We are subject to certain market risks including, but 
not limited to, changes in commodity prices for elec-
tricity, coal, environmental emissions and gas and 
fluctuations in interest rates. We use various market 
risk sensitive instruments, including derivative con-
tracts, primarily to limit our exposure to fluctuations in 
commodity pricing. Our Commodity Risk Management 
Committee (CRMC), comprising of members of senior 
management, is responsible for establishing risk man-
agement policies and the monitoring and reporting of 
risk exposures relating to our DP&L-operated genera-
tion units. The CRMC meets on a regular basis with 
the objective of identifying, assessing and quantifying 
material risk issues and developing strategies to  
manage these risks.

Commodity Pricing Risk 

Commodity pricing risk exposure includes the impacts 
of weather, market demand, increased competition 
and other economic conditions. To manage the volatil-
ity relating to these exposures at our DP&L-operated 
generation units, we use a variety of non-derivative 
and derivative instruments including forward contracts 
and futures contracts. These derivative instruments 
are used principally for economic hedging purposes 
and none are held for trading purposes. The major-
ity of our commodity contracts are not considered 
derivative instruments under GAAP and are therefore 
excluded from MTM accounting. Derivatives that fall 
within the scope of derivative accounting under GAAP 
must be recorded at their fair value and marked to 
market unless they qualify for hedge accounting. MTM 
gains and losses on derivative instruments that qualify 
for hedge accounting are deferred in AOCI until the 
forecasted transactions occur. We adjust the derivative 
instruments that do not qualify for cash flow hedging  
to fair value on a monthly basis and where applicable,  
we recognize a corresponding Regulatory asset for 
above-market costs or a regulatory liability for below-
market costs in accordance with Regulatory account-
ing under GAAP. 

During 2008 and 2009, the coal market has expe-

rienced unprecedented price volatility. The coal market 
has increasingly been influenced by both international 
and domestic supply and consumption and, while we 
have all of the total expected coal volume needed to 
meet our retail and firm wholesale sales requirements 

DPL Inc. 

55

 
for 2010 under contract, sales requirements may 
change, particularly for retail load. To the extent we 
are not able to hedge against price volatility or recover 
increases through our fuel rider that began in January 
2010, our results of operations, financial position or 
cash flows could be materially affected.

The following table provides a reconciliation of the 

MTM positions of the commodity derivative contracts 
included on our balance sheets at December 31, 2009:

corresponding 10% change in the portion of purchased 
power used as part of the sale (note the share of  
the internal generation used to meet the wholesale  
sale would not be affected by the 10% change in

The net asset/liability of the MTM positions above are

For purposes of potential risk analysis, we use a 

sensitivity analysis to quantify potential impacts of mar-
ket rate changes on the statements of results of opera-
tions. The sensitivity analysis represents hypothetical 
changes in market values that may or may not occur  
in the future. 

Approximately 16% of DPL’s and 19% of DP&L’s 

electric revenues for the year ended December 31, 
2009 were from sales of excess energy and capacity  
in the wholesale market. Energy in excess of the  
needs of existing retail customers is sold in the  
wholesale market when we can identify opportunities 
with positive margins. 

The table below provides the effect on annual Net 

income as of December 31, 2009, of a hypothetical 
increase or decrease of 10% in the price per megawatt 
hour of wholesale power, including the impact of a  

DPL’s fuel (including coal, gas, oil and emission allow-
ances) and purchased power costs as a percentage 
of total operating costs in the years ended December 
31, 2009 and 2008 were 33% and 33%, respectively. 
DP&L’s fuel (including coal, gas, oil and emission 
allowances) and purchased power costs as a percent-
age of total operating costs were 33% and 34% for the 
years ended December 31, 2009 and 2008, respec-
tively. We have substantially all of the total expected 
coal volume needed to meet our retail and firm whole-
sale sales requirements for 2010 under contract. The 
majority of our contracted coal is purchased at fixed 
prices although some contracts provide for periodic 
pricing adjustments. We do not expect to purchase 
SO2 allowances for 2010; however, the exact consump-
tion of SO2 allowances will depend on market prices 
for power, availability of our generation units and the 
actual sulfur content of the coal burned. We do not 
plan to purchase NOx allowances for 2010. Fuel costs 
are impacted by changes in volume and price and are 
driven by a number of variables including weather, reli-
ability of coal deliveries, scheduled outages and gen-
eration plant mix. 

Purchased power costs depend, in part, upon the 
timing and extent of planned and unplanned outages 
of our generating capacity. We will purchase power on 
a discretionary basis when wholesale market condi-
tions provide opportunities to obtain power at a cost 
below our internal generation costs. 

Effective January 1, 2010, DP&L is allowed to 
recover its Ohio retail jurisdictional share of fuel and 
purchased power costs, of approximately 80%, as 
part of the fuel rider approved by the PUCO. The table 
below provides the effect on annual net income as 
of December 31, 2009, of a hypothetical increase or 
decrease of 10% adjusted for the approximate 80% 
recovery in the prices of fuel and purchased power:

Interest Rate Risk

As a result of our normal investing and borrowing activities, our financial results are exposed to fluctuations in  
interest rates, which we manage through our regular financing activities. We maintain both cash on deposit and 
investments in cash equivalents that may be affected by adverse interest rate fluctuations. DPL has fixed-rate 
long-term debt and DP&L has both fixed and variable-rate long-term debt. DP&L’s variable-rate debt is comprised 
of publicly held pollution control bonds. The variable-rate bonds bear interest based on a prevailing rate that is 
reset weekly based on a comparable market index. Market indexes can be affected by market demand, supply, 
market interest rates and other economic conditions. 

The carrying value of DPL’s debt was $1,324.1 million at December 31, 2009, consisting of DP&L’s first 
mortgage bonds, DP&L’s tax-exempt pollution control bonds, DP&L’s revolving credit facilities, DPL’s unsecured 
notes and DP&L’s capital lease. The fair value of this debt was $1,317.6 million, based on current market prices
 or discounted cash flows using current rates for similar issues with similar terms and remaining maturities.

Long-term Debt Interest Rate Risk Sensitivity Analysis 

Our estimate of market risk exposure is presented for our fixed-rate and variable-rate debt at December 31, 2009 
and 2008 for which an immediate adverse market movement causes a potential material impact on our financial 
position, results of operations, or the fair value of the debt. We believe that the adverse market movement  
represents the hypothetical loss to future earnings and does not represent the maximum possible loss nor any 
expected actual loss, even under adverse conditions, because actual adverse fluctuations would likely differ.

DPL’s debt is comprised of both fixed-rate debt and variable-rate debt. In regard to fixed rate debt, the interest 
rate risk with respect to DPL’s long-term debt, excluding capital lease obligations, primarily relates to the potential 
impact a decrease of one percentage point in interest rates has on the fair value of DPL $1,224.1 million of 
fixed-rate debt and not on DPL’s financial position or results of operations. On the variable-rate debt, the interest 
rate risk with respect to DPL’s long-term debt represents the potential impact an increase of one percentage point 
in the interest rate has on DPL’s results of operations related to DP&L’s $100 million variable-rate long-term debt 
outstanding as of December 31, 2009.

DP&L’s interest rate risk with respect to DP&L’s long-term debt primarily relates to the potential impact a 
decrease in interest rates of one percentage point has on the fair value of DP&L’s $784.3 million of fixed-rate debt 
and not on DP&L’s financial position or DP&L’s results of operations. On the variable-rate debt, the interest rate 
risk with respect to DP&L’s long-term debt represents the potential impact an increase of one percentage point in 
the interest rate has on DP&L’s results of operations related to DP&L’s $100 million variable-rate long-term debt 
outstanding as of December 31, 2009.

Equity Price Risk

As of December 31, 2009, approximately 35.0% of the defined benefit pension plan assets were comprised of 
investments in equity securities and 65.0% related to investments in fixed income securities, cash and cash  
equivalents, and alternative investments. The equity securities are carried at their market value of approximately 
$85.1 million at December 31, 2009. A hypothetical 10% decrease in prices quoted by stock exchanges  
would result in an $8.5 million reduction in fair value as of December 31, 2009 and approximately a $0.5 million 
increase to the 2010 pension expense. 

Credit Risk

Credit risk is the risk of an obligor’s failure to meet the terms of any investment contract, loan agreement or  
otherwise perform as agreed. Credit risk arises from all activities in which success depends on issuer, borrower  
or counterparty performance, whether reflected on or off the balance sheet. We limit our credit risk by assessing 
the creditworthiness of potential counterparties before entering into transactions with them and continue to  
evaluate their creditworthiness after transactions have been originated. We use the three leading corporate credit 
rating agencies and other current market-based qualitative and quantitative data to assess the financial strength  
of counterparties on an ongoing basis. We may require various forms of credit assurance from counterparties in 
order to mitigate credit risk.

Critical Accounting Estimates 

DPL’s and DP&L’s Consolidated Financial Statements 
are prepared in accordance with U.S. GAAP. In con-
nection with the preparation of these financial state-
ments, our management is required to make assump-
tions, estimates and judgments that affect the reported 
amounts of assets, liabilities, revenues, expenses  
and the related disclosure of contingent liabilities.  
These assumptions, estimates and judgments are 
based on our historical experience and assump-
tions that we believed to be reasonable at the time. 
However, because future events and their effects  
cannot be determined with certainty, the determination 
of estimates requires the exercise of judgment.  
Our critical accounting estimates are those which 
require assumptions to be made about matters that  
are highly uncertain.

Different estimates could have a material effect 

on our financial results. Judgments and uncertainties 
affecting the application of these policies and esti-
mates may result in materially different amounts being 
reported under different conditions or circumstances. 
Historically, however, recorded estimates have not dif-
fered materially from actual results. Significant items 
subject to such judgments include: the carrying value 
of property, plant and equipment; unbilled revenues; 
the valuation of derivative instruments; the valuation of 
insurance and claims liabilities; the valuation of allow-
ances for receivables and deferred income taxes; 
regulatory assets and liabilities; reserves recorded for 
income tax exposures; litigation; contingencies; the 
valuation of AROs; and assets and liabilities related to 
employee benefits.

Impairments and Assets Held for Sale: In accordance 
with the provisions of GAAP relating to the account-
ing for impairments, long-lived assets to be held and 
used are reviewed for impairment whenever events or 
circumstances indicate that the carrying amount may 
not be recoverable. When required, impairment losses 
on assets to be held and used are recognized based 
on the fair value of the asset. We determine the fair 
value of these assets based upon estimates of future 
cash flows, market value of similar assets, if available 
or independent appraisals, if required. In analyzing the 
fair value and recoverability using future cash flows, we 
make projections based on a number of assumptions 
and estimates of growth rates, future economic condi-
tions, assignment of discount rates and estimates of 

terminal values. An impairment loss is recognized if the 
carrying amount of the long-lived asset is not recover-
able from its undiscounted cash flows. The measure-
ment of impairment loss is the difference between the 
carrying amount and fair value of the asset. Long-lived 
assets to be disposed of or held for sale are reported 
at the lower of carrying amount or fair value less cost to 
sell. We determine the fair value of these assets in the 
same manner as described for assets held and used. 

Revenue Recognition (including Unbilled Revenue): We 
consider revenue realized, or realizable, and earned 
when persuasive evidence of an arrangement exists, 
the products or services have been provided to the 
customer, the sales price is fixed or determinable, and 
collection is reasonably assured. The determination of 
the energy sales to customers is based on the reading 
of their meters, which occurs on a systematic basis 
throughout the month. We recognize revenues using an 
accrual method for retail and other energy sales that 
have not yet been billed, but where electricity has been 
consumed. This is termed “unbilled revenues” and is a 
widely recognized and accepted practice for utilities. 
At the end of each month, unbilled revenues are deter-
mined by the estimation of unbilled energy provided 
to customers since the date of the last meter reading, 
projected line losses, the assignment of unbilled ener-
gy provided to customer classes and the average  
rate per customer class. Given our estimation method 
and the fact that customers are billed monthly, we 
believe it is unlikely that materially different results  
will occur in future periods when these amounts are 
subsequently billed.

Income Taxes: Judgment and the use of estimates are 
required in developing the provision for income taxes 
and reporting of tax-related assets and liabilities. The 
interpretation of tax laws involves uncertainty, since tax-
ing authorities may interpret them differently. Ultimate 
resolution of income tax matters may result in favorable 
or unfavorable impacts to Net income and cash flows 
and adjustments to tax-related assets and liabilities 
could be material. We have adopted the provisions 
of GAAP relating to the accounting for uncertainty in 
income taxes. Taking into consideration the uncertainty 
and judgment involved in the determination and fil-
ing of income taxes, these GAAP provisions establish 
standards for recognition and measurement in financial 
statements of positions taken, or expected to be taken, 
by an entity on its income tax returns. Positions taken 

DPL Inc. 

59

 
by an entity on its income tax returns that are recog-
nized in the financial statements must satisfy a more-
likely-than-not recognition threshold, assuming that the 
position will be examined by taxing authorities with full 
knowledge of all relevant information. 

Deferred income tax assets and liabilities repre-
sent future effects on income taxes for temporary dif-
ferences between the bases of assets and liabilities 
for financial reporting and tax purposes. We evaluate 
quarterly the probability of realizing deferred tax assets 
by reviewing a forecast of future taxable income and 
the availability of tax planning strategies that can be 
implemented, if necessary, to realize deferred tax 
assets. Failure to achieve forecasted taxable income 
or successfully implement tax planning strategies may 
affect the realization of deferred tax assets.

Regulatory Assets and Liabilities: Application of the 
provisions of GAAP relating to regulatory accounting 
requires us to reflect the effect of rate regulation in 
our Consolidated Financial Statements. For regulated 
businesses subject to federal or state cost-of-service 
rate regulation, regulatory practices that assign costs 
to accounting periods may differ from accounting 
methods generally applied by nonregulated compa-
nies. When it is probable that regulators will permit the 
recovery of current costs through future rates charged 
to customers, we defer these costs as Regulatory 
assets that otherwise would be expensed by nonregu-
lated companies. Likewise, we recognize Regulatory 
liabilities when it is probable that regulators will require 
customer refunds through future rates and when rev-
enue is collected from customers for expenses that are 
not yet incurred. Regulatory assets are amortized into 
expense and Regulatory liabilities are amortized into 
income over the recovery period authorized by  
the regulator. 

We evaluate whether or not recovery of our 
Regulatory assets through future rates is probable  
and make various assumptions in our analyses. The 
expectations of future recovery are generally based 
on orders issued by regulatory commissions or histori-
cal experience, as well as discussions with applicable 
regulatory authorities. If recovery of a regulatory  

asset is determined to be less than probable, it will be 
written off in the period the assessment is made. We 
currently believe the recovery of our Regulatory assets 
is probable. See Note 3 of Notes to Consolidated 
Financial Statements.

AROs: In accordance with the provisions of GAAP 
relating to the accounting for AROs, legal obligations 
associated with the retirement of long-lived assets are 
required to be recognized at their fair value at the time 
those obligations are incurred. Upon initial recognition 
of a legal liability, costs are capitalized as part of the 
related long-lived asset and allocated to expense over 
the useful life of the asset. These GAAP provisions 
also require that components of previously recorded 
depreciation related to the cost of removal of assets 
upon retirement, whether legal AROs or not, must be 
removed from a company’s accumulated deprecia-
tion reserve. We make assumptions, estimates and 
judgments that affect the reported amounts of assets, 
liabilities and expenses as they relate to AROs. These 
assumptions and estimates are based on historical 
experience and assumptions that we believe to be rea-
sonable at the time. 

Insurance and Claims Costs: In addition to insurance 
obtained from third-party providers, MVIC, a wholly-
owned captive subsidiary of DPL, provides insurance 
coverage solely to us, our subsidiaries and, in some 
cases, our partners in commonly-owned facilities we 
operate, for workers’ compensation, general liability, 
property damage, and directors’ and officers’ liabil-
ity. Insurance and Claims Costs on the Consolidated 
Balance Sheets of DPL include insurance reserves 
of approximately $16.2 million and $17.6 million for 
2009 and 2008, respectively. Furthermore, DP&L is 
responsible for claim costs below certain coverage 
thresholds of MVIC for the insurance coverage noted 
above. In addition, DP&L has medical, life and dis-
ability reserves for claims costs below certain coverage 
thresholds of third-party providers. DPL and DP&L 
record these additional insurance and claims costs of 
approximately $11.3 million and $9.8 million for 2009 
and 2008, respectively, within Other current liabilities 
and Other deferred credits on the balance sheets. The 

60  DPL Inc.

MVIC reserves at DPL and the workers’ compensation, 
medical, life and disability reserves at DP&L are actu-
arially determined based on a reasonable estimation of 
insured events occurring. There is uncertainty associ-
ated with the loss estimates and actual results may 
differ from the estimates. Modification of these loss 
estimates based on experience and changed circum-
stances is reflected in the period in which the estimate 
is re-evaluated.

Pension and Postretirement Benefits: We account for 
and disclose pension and postretirement benefits in 
accordance with the provisions of GAAP relating to the 
accounting for pension and other postretirement plans. 
These GAAP provisions require the use of assump-
tions, such as the discount rate and long-term rate of 
return on assets, in determining the obligations, annual 
cost, and funding requirements of the plans. 

For 2010, we are maintaining our long-term rate of 
return assumptions of 8.50% for pension and 6.00% for 
other postemployment benefit plan assets representing 
our long-term assumptions based on our current port-
folio mix. We have decreased our assumed discount 
rate to 5.75% for pension and 5.35% for postretirement 
benefits expense to reflect current duration-based yield 
curve discount rates. A one percent change in the 
rate of return assumption for pension would result in 
an increase or decrease to the 2010 pension expense 
of approximately $2.5 million. A one percent change 
in the discount rate for pension would result in an 
increase or decrease to the 2010 pension expense of 
approximately $2.0 million. We do not anticipate any 
special adjustments to expense in 2010.

In future periods, differences in the actual return 
on pension and other post-employment benefit plan 
assets and assumed return, or changes in the discount 
rate, will affect the timing of contributions to the plans, 
if any. We provide postretirement health care benefits 
to employees who retired prior to 1987. A one percent-
age point change in the assumed health care cost 
trend rate would affect postretirement benefit costs by 
approximately $0.1 million.

Contingent and Other Obligations: During the conduct 
of our business, we are subject to a number of federal 

and state laws and regulations, as well as other factors 
and conditions that potentially subject us to environ-
mental, litigation, insurance and other risks. We peri-
odically evaluate our exposure to such risks and record 
reserves for those matters where a loss is considered 
probable and reasonably estimable in accordance 
with GAAP. In recording such reserves, we may make 
assumptions, estimates and judgments that affect the 
reported amounts of assets, liabilities and expenses as 
they relate to contingent and other obligations. These 
assumptions and estimates are based on historical 
experience and assumptions and may be subject to 
change. We, however, believe such estimates and 
assumptions are reasonable.

Notes to Consolidated Financial Statements

This report includes the combined filing of DPL and 
DP&L. DP&L is the principal subsidiary of DPL pro-
viding approximately 98% of DPL’s total consolidated 
revenue and approximately 95% of DPL’s total consoli-
dated asset base. Throughout this report, the terms 
“we,” “us,” “our” and “ours” are used to refer to both 
DPL and DP&L, respectively and altogether, unless the 
context indicates otherwise. Discussions or areas of 
this report that apply only to DPL or DP&L will clearly 
be noted in the section.

Some of the Notes presented in this report are only 

applicable to DPL or DP&L as indicated. The other 
Notes apply to both registrants and the financial infor-
mation presented is segregated by registrant.

1 Overview and Summary of Significant 
Accounting Policies

Description of Business 

DPL is a diversified regional energy company orga-
nized in 1985 under the laws of Ohio. DPL’s principal 
subsidiary is DP&L. DP&L is a public utility incorporat-
ed in 1911 under the laws of Ohio. DP&L is engaged 
in generation, transmission, distribution and the sale 
of electricity to residential, commercial, industrial and 
governmental customers in a 6,000 square mile area 
of West Central Ohio. Electricity for DP&L’s 24 county 
service area is primarily generated at eight coal-fired 
power plants and is distributed to more than 500,000 
retail customers. Principal industries served include 
automotive, food processing, paper, plastic manufac-
turing and defense. 

DP&L’s sales reflect the general economic condi-

tions and seasonal weather patterns of the area. DP&L 
sells any excess energy and capacity into the whole-
sale market. 

DPL’s other significant subsidiaries include DPLE, 

which engages in the operation of peaking generat-
ing facilities; DPLER, which is a CRES provider selling 
retail electric energy and other energy services; and 
MVIC, our captive insurance company that provides 
insurance services to us and our subsidiaries. All of 
DPL’s subsidiaries are wholly-owned.

DPL also has a wholly-owned business trust, 
DPL Capital Trust II, formed for the purpose of issuing 
trust capital securities to investors. 

DPL and DP&L conduct their principal business 

in one business segment – Electric. 

DP&L’s electric transmission and distribution busi-

nesses are subject to rate regulation by federal and 
state regulators while its generation business is not 
subject to such regulation. Accordingly, DP&L applies 
the accounting standards for regulated operations to 

its electric transmission and distribution businesses 
and records regulatory assets when incurred costs are 
expected to be recovered in future customer rates, and 
regulatory liabilities when current cost recoveries in 
customer rates relate to expected future costs.

Financial Statement Presentation 

We prepare Consolidated Financial Statements for 
DPL. DPL’s Consolidated Financial Statements include 
the accounts of DPL and its wholly-owned subsidiar-
ies. DPL Capital Trust II is not consolidated, consistent 
with the provisions of GAAP relating to variable interest 
entities. 

DP&L has an undivided ownership interest in 
seven electric generating facilities and numerous trans-
mission facilities. These undivided interests in jointly 
owned facilities are accounted for on a pro rata basis 
in DP&L’s Financial Statements. 

All material intercompany accounts and transac-

tions are eliminated in consolidation. 

We have evaluated all subsequent events through 

February 11, 2010 which is the date these financial 
statements were filed with the SEC.

The preparation of financial statements in con-
formity with GAAP requires us to make estimates and 
judgments that affect the reported amounts of assets 
and liabilities, the disclosure of contingent assets and 
liabilities, and the revenue and expenses of the periods 
reported. Actual results could differ from those esti-
mates. Significant items subject to such estimates and 
judgments include: the carrying value of property, plant 
and equipment; unbilled revenues; the valuation of 
derivative instruments; the valuation of insurance and 
claims liabilities; the valuation of allowances for receiv-
ables and deferred income taxes; regulatory assets 
and liabilities; reserves recorded for income tax expo-
sures; litigation; contingencies; the valuation of AROs; 
and assets and liabilities related to employee benefits.

Revisions 

During the preparation of our annual report on Form 
10-K for the year ended December 31, 2009, we identi-
fied certain immaterial items that had not been cor-
rectly presented in our prior period balance sheets. 
Accordingly, we have made the following adjustments 
to our prior period balance sheets to conform to the 
current period presentation. These adjustments did 
not have any impact on our gross margin, operating 
income, net income, earnings per share or cash flows 
as previously reported.

Property Taxes 

Certain accrued taxes representing property tax 
liabilities had been previously classified as a current 
liability and should have been classified as a noncur-

70  DPL Inc.

rent liability. As a result of this reclassification, accrued 
taxes decreased at DPL by $57.5 million from $130.4 
million to $72.9 million and also by the same $57.5 mil-
lion at DP&L from $128.0 million to $70.5 million as of 
December 31, 2008. This same reclassification also 
increased other deferred credits at DPL by $57.5 mil-
lion from $50.7 million to $108.2 million and at DP&L 
by $57.5 million from $50.8 million to $108.3 million as 
of December 31, 2008. 

Deferred Taxes 

Certain deferred taxes that related to amounts record-
ed in accumulated other comprehensive income/(loss) 
for pension-related costs had been previously classi-
fied within deferred taxes and should have been classi-
fied within accumulated other comprehensive income/
(loss). In addition, certain deferred taxes that related 
to amounts recoverable from customers in future rates 
had also been incorrectly presented. As a result of 
these two deferred tax items, deferred taxes decreased 
at DPL by $59.6 million from $433.7 million to $374.1 
million and at DP&L by $59.5 million from $417.8 mil-
lion to $358.3 million as of December 31, 2008. These 
same reclassifications also decreased accumulated 
other comprehensive loss at DPL by $21.5 million 
from $44.6 million to $23.1 million and at DP&L by 
$21.4 million from $37.5 million to $16.1 million and 
decreased regulatory assets at both DPL and DP&L 
by $38.1 million from $233.7 million to $195.6 million 
as of December 31, 2008. These reclassifications also 
resulted in an increase in accumulated other compre-
hensive income at DPL by $9.8 million from a loss of 
$9.2 million to income of $0.6 million and at DP&L by 
$10.6 million from $6.5 million to $17.1 million as of 
December 31, 2007 and an increase in accumulated 
other comprehensive income at DPL by $11.3 million 
from a loss of $6.5 million to income of $4.8 million and 
at DP&L by $13.0 million from $15.1 million to $28.1 
million as of December 31, 2006. 

Revenue Recognition 

Revenues are recognized from retail and wholesale 
electricity sales and electricity transmission and distri-
bution delivery services. We consider revenue realized, 
or realizable, and earned when persuasive evidence of 
an arrangement exists, the products or services have 
been provided to the customer, the sales price is fixed 
or determinable, and collection is reasonably assured. 
The determination of energy sales to customers is 
based on the reading of their meters and this occurs 
on a systematic basis throughout the month. We rec-
ognize the revenues on our statements of results of 
operations using an accrual method for retail and other 
energy sales that have not yet been billed, but where 

electricity has been consumed. This is termed “unbilled 
revenues” and is a widely recognized and accepted 
practice for utilities. At the end of each month, unbilled 
revenues are determined by the estimation of unbilled 
energy provided to customers since the date of the last 
meter reading, projected line losses, the assignment of 
unbilled energy provided to customer classes and the 
average rate per customer class. 

All of the power produced at the generation plants 
is sold to an RTO and we in turn purchase it back from 
the RTO to supply our customers. These power sales 
and purchases are reported on a net hourly basis as 
revenues or purchased power on our statements of 
results of operations. We record expenses when pur-
chased electricity is received and when expenses are 
incurred, with the exception of the ineffective portion 
of certain power purchase contracts that are deriva-
tives and qualify for hedge accounting, as well as cer-
tain derivative contracts that do not qualify for hedge 
accounting, causing gains or losses to be recorded 
prior to the receipt of electricity.

Allowance for Uncollectible Accounts 

We establish provisions for uncollectible accounts 
by using both historical average loss percentages to 
project future losses and by establishing specific provi-
sions for known credit issues.

Property, Plant and Equipment 

We record our ownership share of our undivided inter-
est in jointly-held plants as an asset in property, plant 
and equipment. Property, plant and equipment are 
stated at cost. For regulated transmission and distribu-
tion property, cost includes direct labor and material, 
allocable overhead expenses and an allowance for 
funds used during construction (AFUDC). AFUDC rep-
resents the cost of borrowed funds and equity used to 
finance regulated construction projects. Capitalization 
of AFUDC ceases at either project completion or at 
the date specified by regulators. AFUDC capitalized in 
2009, 2008 and 2007 was not material. 

For unregulated generation property, cost includes 
direct labor and material, allocable overhead expenses 
and interest capitalized during construction using the 
provisions of GAAP relating to the accounting for capi-
talized interest. Capitalized interest was $2.4 million in 
2009, $8.9 million in 2008 and $21.8 million in 2007. 

For substantially all depreciable property, when a 
unit of property is retired, the original cost of that prop-
erty less any salvage value is charged to Accumulated 
depreciation and amortization.

Property is evaluated for impairment when events 
or changes in circumstances indicate that its carrying 
amount may not be recoverable.

Repairs and Maintenance 

Costs associated with maintenance activities, primarily power plant outages, are recognized at the time the work 
is performed. These costs, which include labor, materials and supplies, and outside services required to maintain 
equipment and facilities, are capitalized or expensed based on FERC-defined units of property.

Depreciation 

Depreciation expense is calculated using the straight-line method, which allocates the cost of property over its esti-
mated useful life. For DPL’s generation, transmission, and distribution assets, straight-line depreciation is applied 
on an average annual composite basis using group rates that approximated 2.7% in 2009, 2.7% in 2008 and 2.9% 
in 2007. In July 2007, DPL completed a depreciation rate study for non-regulated generation property based on its 
property, plant and equipment balances during 2007. The results of the depreciation study concluded that DPL’s 
depreciation rates should be reduced due to projected asset lives beyond previously estimated useful lives. DPL 
adjusted the depreciation rates for its non-regulated generation property, effective August 1, 2007. For the period 
from August 1, 2007 to December 31, 2007, the reduction in depreciation expense increased income from continu-
ing operations by approximately $9.5 million, increased net income by approximately $6.0 million, and increased 
basic EPS by approximately $0.06 per share.

AROs 
We recognize AROs in accordance with GAAP. GAAP 
requires legal obligations associated with the retire-
ment of long-lived assets to be recognized at their fair 
value at the time those obligations are incurred. Upon 
initial recognition of a legal liability, costs are capital-
ized as part of the related long-lived asset and depre-
ciated over the useful life of the related asset. Our 
legal obligations associated with the retirement of our 
long-lived assets consisted primarily of river intake and 
discharge structures, coal unloading facilities, loading 
docks, ice breakers and ash disposal facilities. Our 
generation AROs are recorded within other deferred 
credits on the balance sheets.

Estimating the amount and timing of future expen-

ditures of this type requires significant judgment. 
Management routinely updates these estimates as 
additional information becomes available.

Asset Removal Costs 
We continue to record cost of removal for our regu-
lated transmission and distribution assets through our 
depreciation rates and recover those amounts in rates 
charged to our customers. There are no known legal 
AROs associated with these assets. We have recorded 
$99.1 million and $96.0 million in estimated costs of 
removal at December 31, 2009 and 2008, respectively, 
as regulatory liabilities for our transmission and distri-
bution property. These amounts represent the excess 
of the cumulative removal costs recorded through 
depreciation rates versus the cumulative removal costs 
actually incurred. See Note 3 of Notes to Consolidated 
Financial Statements.

Regulatory Accounting 

In accordance with GAAP, regulatory assets and 
liabilities are recorded in the balance sheets for our 
regulated transmission and distribution businesses. 
Regulatory assets are the deferral of costs expected to 
be recovered in future customer rates and Regulatory 
liabilities represent current recovery of expected future 
costs.

We evaluate our Regulatory assets each period 

and believe recovery of these assets is probable. We 
have received or requested a return on certain regula-
tory assets for which we are currently recovering or 
seeking recovery through rates. We record a return 
after it has been authorized in an order by a regulator. 
If we were required to terminate application of these 
GAAP provisions for all of our regulated operations, 
we would have to write off the amounts of all regula-
tory assets and liabilities to the statements of results 
of operations at that time. See Note 3 of Notes to 
Consolidated Financial Statements.

Inventories 

Inventories are carried at average cost and include 
coal, limestone, oil and gas used for electric  
generation, and materials and supplies used for utility 
operations. 

We account for our emission allowances as inven-

tory and record emission allowance inventory at 
weighted average cost. We calculate the weighted 
average cost by each vintage (year) for which emission 
allowances can be used and charge to fuel costs the 
weighted average cost of emission allowances used 
each month. Net gains or losses on the sale of excess 
emission allowances, representing the difference 
between the sales proceeds and the weighted average 
cost of emission allowances, are recorded as a com-
ponent of our fuel costs and are reflected in Operating 
income when realized. During the periods ended 
December 31, 2009, 2008 and 2007, we recognized 
gains from the sale of emission allowances in  
the amounts of $5.0 million, $34.8 million and $1.2  
million, respectively. Beginning in January 2010, most 
of the gains on emission allowances will be used  
to reduce the overall fuel rider charged to the Ohio 
retail jurisdiction.

At December 31, 2009, we had substantially 

placed into service FGD equipment at most of our 
DP&L and partner-operated facilities.

Income Taxes 

GAAP requires an asset and liability approach for 
financial accounting and reporting of income taxes with 
tax effects of differences, based on currently enacted 
income tax rates, between the financial reporting and 
tax basis of accounting reported as deferred tax assets 
or liabilities in the balance sheets. Deferred tax assets 
are recognized for deductible temporary differences. 
Valuation allowances are provided against deferred tax 
assets unless it is more likely than not that the asset 
will be realized.

Investment tax credits, which have been used 

to reduce federal income taxes payable, have been 
deferred for financial reporting purposes. These 
deferred investment tax credits are amortized over the 
useful lives of the property to which they are related. 
For rate-regulated operations, additional deferred 
income taxes and offsetting regulatory assets or liabili-
ties are recorded to recognize that income taxes will be 
recoverable or refundable through future revenues. 

DPL files a consolidated U.S. federal income tax 
return in conjunction with its subsidiaries. The consoli-
dated tax liability is allocated to each subsidiary based 
on the separate return method which is specified in our 
tax allocation agreement and which provides a consis-
tent, systematic and rational approach. See Note 8 of 
Notes to Consolidated Financial Statements.

Accounting for Taxes Collected from Customers 
and Remitted to Governmental Authorities

DP&L collects certain excise taxes levied by state or 
local governments from its customers. DP&L’s excise 
taxes are accounted for on a gross basis and recorded 
as revenues and general taxes in the accompanying 
Statements of Results of Operations as follows: 

For the years ended December 31,

for employee share options and other similar instru-
ments at the grant date are estimated using option-
pricing models and any excess tax benefits are recog-
nized as an addition to paid-in capital. The reduction in 
income taxes payable from the excess tax benefits is 
presented in the statements of cash flows within Cash 
flows from financing activities. See Note 12 of Notes to 
Consolidated Financial Statements.

Cash and Cash Equivalents

Cash and cash equivalents are stated at cost, which 
approximates fair value. All highly liquid short-term 
investments with original maturities of three months or 
less are considered cash equivalents.

Financial Instruments 

We classify our investments in debt and equity finan-
cial instruments of publicly traded entities into differ-
ent categories: held-to-maturity and available-for-sale. 
Available-for-sale securities are carried at fair value 
and unrealized gains and losses on those securi-
ties, net of deferred income taxes, are presented as 
a separate component of shareholders’ equity. Other-
than-temporary declines in value are recognized cur-
rently in earnings. Financial instruments classified as 
held-to-maturity are carried at amortized cost. The 
cost basis for public equity security and fixed matu-
rity investments is average cost and amortized cost, 
respectively.

Financial Derivatives 

All derivatives are recognized as either assets or liabili-
ties in the balance sheets and are measured at fair 
value. Changes in the fair value are recorded in earn-
ings unless they are designated as a cash flow hedge 
of a forecasted transaction or qualify for the normal 
purchases and sales exception.

Stock-Based Compensation 

We measure the cost of employee services received 
and paid with equity instruments based on the fair-
value of such equity on the grant date. This cost is 
recognized in results of operations over the period that 
employees are required to provide service. Liability 
awards are initially recorded based on the fair-value of 
equity instruments and are to be re-measured for the 
change in stock price at each subsequent reporting 
date until the liability is ultimately settled. The fair-value 

our exposure to changes in energy and commodity 
prices and as a hedge against the risk of changes in 
cash flows associated with expected electricity pur-
chases. These purchases are required to meet full load 
requirements during times of peak demand or during 
planned and unplanned generation facility outages. We 
also hold forward sales contracts that hedge against 
the risk of changes in cash flows associated with 
power sales during periods of projected generation 
facility availability. We use cash flow hedge accounting 
when the hedge is deemed to be effective and MTM 
accounting when the hedge is not effective. See Note 
11 of Notes to Consolidated Financial Statements.

Insurance and Claims Costs 

In addition to insurance obtained from third-party providers, MVIC, a wholly-owned captive subsidiary of DPL, 
provides insurance coverage to us, our subsidiaries and, in some cases, our partners in commonly owned  
facilities we operate, for workers’ compensation, general liability, property damage, and directors’ and officers’ 
liability. Insurance and claims costs on the Consolidated Balance Sheets of DPL include insurance reserves of 
approximately $16.2 million and $17.6 million for 2009 and 2008, respectively. Furthermore, DP&L is responsible 
for claim costs below certain coverage thresholds of MVIC for the insurance coverage noted above. In addition, 
DP&L has medical, life, and disability reserves for claims costs below certain coverage thresholds of third-party 
providers. DPL and DP&L record these additional insurance and claims costs of approximately $11.3 million 
and $9.8 million for 2009 and 2008, respectively, within Other current liabilities and Other deferred credits on the 
balance sheets. The MVIC reserves at DPL and the workers’ compensation, medical, life, and disability reserves 
at DP&L are actuarially determined based on a reasonable estimation of insured events occurring. There is 
uncertainty associated with these loss estimates and actual results may differ from the estimates. Modification  
of these loss estimates based on experience and changed circumstances is reflected in the period in which the 
estimate is re-evaluated.

DPL Capital Trust II
DPL has a wholly-owned business trust, DPL Capital Trust II (the Trust), formed for the purpose of issuing trust 
capital securities to third-party investors. Effective 2003, DPL deconsolidated the Trust upon adoption of 
the accounting standards related to variable interest entities and currently treats the Trust as a nonconsolidated 
subsidiary. The Trust, which holds mandatorily redeemable trust capital securities, is reported as two components 
on DPL’s consolidated balance sheet. The investment in the Trust, which amounts to $3.8 million and $5.5 million 
at December 31, 2009 and 2008, respectively, is included in Other deferred assets within Other noncurrent  
assets. DPL also has a note payable to the Trust amounting to $142.6 million and $195.0 million at December 31, 
2009 and 2008, respectively, that was established upon the Trust’s deconsolidation in 2003. See Note 7 of Notes  
to Consolidated Financial Statements.

In addition to the obligations under the note payable mentioned above, DPL also agreed to a security obliga-

tion which represents a full and unconditional guarantee of payments to the capital security holders of the Trust. 

Pension and Postretirement Benefits
We recognize the funded status of our benefit plan; recognize as a component of other comprehensive income 
(OCI), net of tax, the gains or losses and prior service costs or credits that arise during the period but are not  
recognized as components of net periodic benefit cost; measure defined benefit plan assets and obligations  
as of the date of our fiscal year-end; and disclose in Notes to Consolidated Financial Statements additional infor-
mation about certain effects on net periodic benefit costs for the next fiscal year that arise from delayed recognition 
of the gains or losses, prior service costs or credits, and transition assets or obligations. See Note 9 of Notes to 
Consolidated Financial Statements.

Recently Adopted Accounting Standards 

FASB Codification

We adopted FASC 105, “Generally Accepted 
Accounting Principles” (formerly SFAS No. 168, “The 
FASB Accounting Standards Codification and the 
Hierarchy of Generally Accepted Accounting Principles 
– a replacement of FASB Statement No. 162”), on 
September 30, 2009. The objective of this Statement  
is to replace Statement No. 162 and to establish the 
FASC as the source of authoritative accounting prin-
ciples recognized by the FASB to be applied by non-
governmental entities in the preparation of financial 
statements in conformity with GAAP. Rules and inter-
pretive releases of the SEC under authority of federal 
securities laws are also sources of authoritative  
GAAP for SEC registrants. This update did not have 
a material impact on our overall results of operations, 
financial position or cash flows.

Disclosures about Derivative Instruments and  
Hedging Activities

We adopted an update to FASC 815, “Derivatives and 
Hedging” (formerly SFAS No. 161, “Disclosures about 
Derivative Instruments and Hedging Activities – an 
amendment to FASB Statement No. 133”), on January 
1, 2009. This update requires an entity to provide 
enhanced disclosures about: (a) how and why an entity 
uses derivative instruments; (b) how derivative instru-
ments and related hedged items are accounted for 
under FASC 815 and its related interpretations; and 
(c) how derivative instruments and related hedged 
items affect an entity’s financial position, financial per-
formance and cash flows. This update did not have 
a material impact on our overall results of operations, 
financial position or cash flows. See Note 11 of Notes 
to Consolidated Financial Statements.

Participating Securities and EPS

We adopted an update to FASC 260, “Earnings 
per Share” (formerly Staff Position EITF 03-6-1, 
“Determining Whether Instruments Granted in Share-
Based Payment Transactions Are Participating 
Securities”) on January 1, 2009. This update clarifies 
that unvested share-based awards that contain non-
forfeitable rights to dividends or dividend equivalents 
(whether paid or unpaid) are participating securities 
and must be included in the computation of EPS  

pursuant to the two-class method. This update did  
not have a material impact on our overall results of 
operations, financial position or cash flows. 

Meaning of “Indexed to a Company’s Own Stock”

We adopted an update to FASC 815, “Derivatives and 
Hedging” (formerly EITF Issue No. 07-5, “Determining 
Whether an Instrument (or Embedded Feature) is 
Indexed to an Entity’s Own Stock”), on January 1, 2009. 
This update gives guidance on when a financial instru-
ment is considered to be indexed to a company’s own 
stock to meet the criteria for FASC 815-10-15-74(a) 
(formerly paragraph 11(a) of FASB Statement No. 133, 
“Accounting for Derivative Financial Instruments.”) This 
update did not have a material impact on our overall 
results of operations, financial position or cash flows.

Interim Disclosures about Fair Value of  
Financial Instruments

We adopted an update of FASC 825, “Financial 
Instruments” (formerly Staff Position SFAS 107-1 and 
APB 28-1, “Interim Disclosures about Fair Value of 
Financial Instruments”), on June 30, 2009. This update 
requires disclosure about the fair value of financial 
instruments for interim reporting periods of publicly 
traded companies as well as in annual financial state-
ments. This update did not have a material impact 
on our overall results of operations, financial position 
or cash flows. See Note 10 of Notes to Consolidated 
Financial Statements.

Subsequent Events

We adopted FASC 855, “Subsequent Events” (for-
merly SFAS 165), on June 30, 2009. FASC 855 incor-
porates the guidance in the American Institute of 
Certified Public Accountants’ Auditing Standard 560 
– Subsequent Events, into the accounting guidance. 
This new standard does not change current accounting 
practices. FASC 855 did not have a material impact  
on our overall results of operations, financial position  
or cash flows.

Disclosures about Pensions and Other  
Postretirement Benefits

We adopted an update to FASC 715, “Compensation – 
Retirement Plans” (formerly Staff Position SFAS 132(R)-
1, “Employers’ Disclosures about Postretirement Benefit 
Plan Assets”), on December 31, 2009. This update

Recently Issued Accounting Standards 

Variable Interest Entities

In June 2009, the FASB issued ASU 2009-02 “Omnibus 
Update” (formerly SFAS No. 167, a revision to FASB 
Interpretation No. 46(R), “Consolidation of Variable 
Interest Entities,”) (ASU 2009-02) that is effective 
for annual reporting periods beginning after November 
15, 2009. We expect to adopt this ASU in the first 
quarter of 2010. This standard updates FASC 810, 
“Consolidation.” ASU 2009-02 changes how a com-
pany determines when an entity that is insufficiently 
capitalized or is not controlled through voting (or  
similar rights) should be consolidated. The determina-
tion of whether a company is required to consolidate  
an entity is based on, among other things, an entity’s 
purpose and design and a company’s ability to  
direct the activities of the entity that most significantly 
impact the entity’s economic performance. We do  
not expect these new rules to have a material impact 
on our overall results of operations, financial position  
or cash flows.

Fair Value Disclosures

In January 2010, the FASB issued ASU 2010-06 “Fair 
Value Measurements and Disclosures” (ASU 2010-06) 
effective for annual reporting periods beginning after 
December 15, 2009. We expect to adopt this ASU  
on January 1, 2010. This standard updates FASC 820, 
“Fair Value Measurements.” ASU 2010-06 requires 
additional disclosures about fair value measurements 
including transfers in and out of Levels 1 and 2 and  
a higher level of disaggregation for the different types 
of financial instruments. For the reconciliation of Level 3 
fair value measurements, information about purchases, 
sales, issuances and settlements should be presented 
separately. We do not expect these new rules to have 
a material impact on our overall results of operations, 
financial position or cash flows.

requires disclosures about benefit plan assets similar 
to the disclosure required in FASC 820, “Fair Value 
Measurements and Disclosures.” It also requires  
discussions on investment allocation decisions, major 
categories of plan assets and significant concentra-
tions of risk in plan assets for the period. This update 
did not have a material impact on our overall results  
of operations, financial position or cash flows. See  
Note 9 of Notes to Consolidated Financial Statements.

Redeemable Equity Instruments

We adopted ASU 2009-04, “Accounting for 
Redeemable Equity Instruments, an amendment to 
Section 480-10-S99,” (ASU 2009-04) on October 1, 
2009. ASU 2009-04 clarifies that SEC Accounting 
Series Release 268 pertains to preferred stocks and 
other redeemable securities including common  
stock, derivative instruments, non-controlling interest, 
securities held by an ESOP and share-based payment 
arrangements with employees. This update did  
not have a material impact on our overall results of 
operations, financial position or cash flows. 

Measuring Liabilities at Fair Value

We adopted ASU 2009-05, “Measuring Liabilities at 
Fair Value,” (ASU 2009-05) on October 1, 2009. ASU 
2009-05 provides additional guidance clarifying the 
measurement of liabilities at fair value. This update  
did not have a material impact on our overall results  
of operations, financial position or cash flows.

Investments in Certain Entities that Calculate  
Net Asset Value per Share

We adopted ASU 2009-12, “Fair Value Measurements 
and Disclosures,” (ASU 2009-12) on December 31, 
2009. ASU 2009-12 updates FASC 820-10, “Fair Value 
Measurements and Disclosures – Overall” and allows, 
as a practical expedient, a reporting entity to measure 
the fair value of an investment that is within the scope 
of these amendments on the basis of the net asset 
value per share of the investment if the net asset value 
of the investment is calculated in a manner consis-
tent with the measurement principles of FASC 946, 
“Financial Services – Investment Companies.” This 
update did not have a material impact on our overall 
results of operations, financial position or cash flows.

3 Regulatory Matters

In accordance with GAAP, regulatory assets and liabilities are recorded in the balance sheets for our regulated 
electric transmission and distribution businesses. Regulatory assets are the deferral of costs expected to be  
recovered in future customer rates and regulatory liabilities represent current recovery of expected future costs  
or gains probable of recovery in future rates.

We evaluate our regulatory assets each period and believe recovery of these assets is probable. We have 

received or requested a return on certain regulatory assets for which we are currently recovering or seeking  
recovery through rates. We record a return after it has been authorized in an order by a regulator. 

Regulatory assets and liabilities on the balance sheets include:

Regulatory Assets

Deferred recoverable income taxes represent deferred income tax assets recognized from the normalization of 
flow-through items as the result of amounts previously provided to customers. This is the cumulative flow-through 
benefit given to regulated customers that will be collected from them in future years. Since currently existing  
temporary differences between the financial statements and the related tax basis of assets will reverse in subse-
quent periods, these deferred recoverable income taxes are amortized.

Pension benefits represent the qualifying FASC 715, “Compensation – Retirement Benefits” costs of our regulated 
operations that for ratemaking purposes are deferred for future recovery. We recognize an asset for a plan’s  
overfunded status or a liability for a plan’s underfunded status, and recognize, as a component of other compre-
hensive income (OCI), the changes in the funded status of the plan that arise during the year that are not  
recognized as a component of net periodic benefit cost. This regulatory asset represents the regulated portion that 
would otherwise be charged as a loss to OCI.

Unamortized loss on reacquired debt represents losses on long-term debt reacquired or redeemed in prior periods. 
These costs are being amortized over the life of the original issues in accordance with FERC rules.

Electric Choice systems costs represent costs incurred to modify the customer billing system for unbundled 
customer rates and electric choice utility bills relative to other generation suppliers and information reports provid-
ed to the state administrator of the low-income payment program. In March 2006, the PUCO issued an order that

approved our tariff as filed. We began collecting  
this rider immediately and expect to recover all costs 
over five years. 

Regional transmission organization costs represent 
costs incurred to join a RTO. The recovery of these 
costs will be requested in a future FERC rate case. In 
accordance with FERC precedence, we are amortizing 
these costs over a 10-year period beginning in 2004 
when we joined the PJM RTO.

TCRR, transmission, ancillary and other PJM-related 
costs represent the costs related to transmission, 
ancillary service and other PJM-related charges that 
have been incurred as a member of PJM. We review 
retail rates and are able to make true-up adjustments 
on an annual basis. 

On February 19, 2009, the PUCO approved 
DP&L’s request to defer transmission, capacity, ancil-
lary and other costs incurred since July 31, 2008 
consistent with the provisions of SB 221. In May 2009, 
the PUCO granted DP&L authority to recover these 
costs through retail rates beginning June 1, 2009. 
Subsequently, an application for rehearing was filed 
claiming the PUCO’s order allowing for recovery of 
RPM capacity costs through a TCRR was unlawful. 
The PUCO issued an order granting rehearing and, on 
September 9, 2009, issued an order directing DP&L to 
remove the deferred and current RPM capacity costs 
from the TCRR rider but also indicating that these RPM 
capacity costs may be recoverable under a separate 
rider. DP&L made a compliance filing on September 
23, 2009, where it removed such costs from the TCRR 
rider and proposed a new RTO RPM rider for the 
recovery of such costs. The PUCO approved the two 
separate riders in November 2009. The sum of the 
rate collected through the current TCRR rider and the 
new RTO RPM rider equals the rate collected through 
the original TCRR rider. Accordingly, during the period 
ended December 31, 2009, DP&L deferred total net 
RTO costs in the amount of $23.5 million. In addition, 
DP&L also deferred $1.1 million relating to Regional 
Transmission Expansion Plan (RTEP) costs and $0.9 
million relating to interest and operation and mainte-
nance expenses. Of the total deferred costs amount-
ing to $25.5 million, $9.8 million relates to the period 
August 1, 2008 through December 31, 2008, and  
$15.7 million relates to the year ended December 31, 
2009. The deferral of these costs resulted in a favor-
able impact to our results of operations.

RPM capacity costs represent the PJM-related costs 
from the calculations of the PJM Reliability Pricing 
Model that allocates capacity among the users of the 
PJM System. As discussed above, DP&L is recovering 

these costs through a PUCO-approved RTO RPM rider. 
The sum of the rate collected through the current  
TCRR rider and the new RTO RPM rider equals the rate 
collected through the original TCRR rider. We review 
this rate and are able to make true-up adjustments to it 
on an annual basis.

Deferred storm costs – 2008 relate to costs incurred 
to repair the damage caused by hurricane force 
winds in September 2008, as well as other major 2008 
storms. On January 14, 2009, the PUCO granted DP&L 
the authority to defer these costs with a return until 
such time that DP&L seeks recovery in a future rate 
proceeding. 

Power plant emission fees represent costs paid to the 
State of Ohio since 2002 for environmental monitoring. 
An application is pending before the PUCO to amend 
an approved rate rider that had been in effect to collect 
fees that were paid and deferred in years prior to 2002. 
The deferred costs incurred prior to 2002 have been 
fully recovered. As the previously approved rate rider 
continues to be in effect, we believe these costs are 
probable of future rate recovery.

CCEM smart grid and advanced metering infrastructure 
costs represent costs incurred as a result of study-
ing and developing distribution system upgrades and 
implementation of advanced metering infrastructure. 
Consistent with the Stipulation, DP&L re-filed its smart 
grid and advanced metering infrastructure business 
cases with the PUCO on August 4, 2009 seeking 
recovery of costs associated with a 10-year plan to 
deploy smart meters, distribution and substation auto-
mation, core telecommunications, supporting software 
and in-home technologies. On August 5, 2009, DP&L 
submitted an application for American Recovery and 
Reinvestment Act (ARRA) funding under the Integrated 
and/or Crosscutting Systems topic area for the Smart 
Grid Investment Grant Program. On October 27, 2009, 
we were notified by the United States Department  
of Energy (DOE) that we will not receive funding under 
the ARRA. A technical conference in this case was 
held at the PUCO in October 2009 for the smart grid 
case, and a subsequent PUCO entry established a 
comment and reply comment period. A hearing is not 
yet scheduled for this case. Based on past PUCO 
precedent and the Ohio legislature’s intent behind 
SB221, we believe these costs are probable of future 
recovery in rates.

CCEM energy efficiency program costs represent 
costs incurred to develop and implement various new 
customer programs addressing energy efficiency. A 
portion of these costs is being recovered over three 
years as part of the Stipulation beginning July 1, 2009; 

80  DPL Inc.

the remaining costs are subject to a two-year true-up process for any over/under recovery of costs. 

Other costs primarily include consumer education advertising costs regarding electric deregulation, settlement 
system costs, other PJM and rate case costs, and alternative energy costs that are or will be recovered over  
various periods. 

Regulatory Liabilities

Estimated costs of removal – regulated property reflect an estimate of amounts collected in customer rates that are 
expected to be incurred to remove existing transmission and distribution property from service upon retirement.

SECA net revenue subject to refund represents our deferral of amounts collected in customer rates during 2005 
and 2006. SECA revenue and expenses represent FERC-ordered transitional payments for the use of transmission 
lines within PJM. A hearing was held in early 2006 to determine if these transitional payments are subject to refund, 
however, no ruling has been issued. We began receiving and paying these transitional payments in May 2005. 

Postretirement benefits represent the qualifying FASC 715, “Compensation – Retirement Benefits” gains related 
to our regulated operations that, for ratemaking purposes, are probable of being reflected in future rates. We  
recognize an asset for a plan’s overfunded status or a liability for a plan’s underfunded status, and recognize, as a 
component of OCI, the changes in the funded status of the plan that arise during the year that are not recognized 
as a component of net periodic benefit cost. This regulatory liability represents the regulated portion that would  
otherwise be reflected as a gain to OCI. 

Other costs primarily include derivative activity related to fuel costs that will be settled over various periods.

4 Ownership of Coal-fired Facilities

DP&L and other Ohio utilities have undivided ownership interests in seven coal-fired electric generating facilities 
and numerous transmission facilities. Certain expenses, primarily fuel costs for the generating units, are allocated 
to the owners based on their energy usage. The remaining expenses, investments in fuel inventory, plant materi-
als and operating supplies, and capital additions are allocated to the owners in accordance with their respective 
ownership interests. As of December 31, 2009, we had $42 million of construction work in process at such facilities. 
DP&L’s share of the operating cost of such facilities is included within the corresponding line in the Statements 
of Results of Operations and DP&L’s share of the investment in the facilities is included in the Balance Sheets. 
DP&L’s undivided ownership interest in such facilities as well as our wholly-owned coal fired Hutchings 

plant at December 31, 2009, is as follows.

5 Assets Sales

Peaker Sales

During 2006, in connection with DPLE’s (a wholly-
owned subsidiary of DPL) decision to sell the 
Greenville Station and Darby Station electric peaking 
generation facilities, DPL concluded that the related 
assets were impaired. Greenville Station consisted  
of four natural gas peaking units with a net book value 
of approximately $66 million. Darby Station consisted 
of six natural gas peaking units with a net book value 
of approximately $156 million. During the fourth  
quarter of 2006, DPL recorded a $71.0 million impair-
ment charge to write-down the assets to their fair value. 
The Greenville Station and Darby Station assets were 
sold by DPLE in April 2007 for $49.2 million and $102.0 
million, respectively, in two separate transactions

Aircraft Sale

On June 7, 2007, Miami Valley CTC, Inc. (an indirect, 
wholly-owned subsidiary of DPL), sold its corporate 
aircraft and associated inventory and parts for $7.4 mil-
lion. The net book value of the assets sold was approx-
imately $1.0 million, and severance and other costs of 
approximately $0.4 million were accrued. Miami Valley 
CTC, Inc. recorded a net gain on the sale of approxi-
mately $6.0 million during the second quarter ending 
June 30, 2007, which was included in DPL’s Operation 
and maintenance expense.

6 Discontinued Operations

On February 13, 2005, DPL’s subsidiaries, MVE, Inc. 
(MVE) and MVIC, entered into an agreement to sell 
their respective interests in forty-six private equity 
funds to AlpInvest/Lexington 2005, LLC, a joint ven-
ture of AlpInvest Partners and Lexington Partners, Inc. 
During 2005, MVE and MVIC completed the sale of 
their interests in forty-three funds and a portion  
of another of those private equity funds. During 2005, 
MVE entered into alternative closing arrangements  
with AlpInvest/Lexington 2005, LLC for funds where 
legal title to said funds could not be transferred until a 
later time. Pursuant to these arrangements, MVE trans-
ferred the economic aspects of the remaining private 
equity funds, consisting of two funds and a portion  
of one fund, to AlpInvest/Lexington 2005, LLC without 
a change in ownership of the interests. The owner-
ship interest in these funds was transferred in 2006 
and 2007, at which time DPL recognized previously 
deferred gains. DPL recognized $18.9 million ($12.1 
million after tax) of these previously deferred gains in 
2006 and the remaining balance of these gains in  
the amount of $7.9 million, net of associated expenses 
($4.9 million after tax), were recognized in 2007. This 
transaction was recorded in discontinued operations 
for each period presented.

As a result of the May 21, 2007 settlement of the 
litigation with three former executives (see Note 17 of 
Notes to Consolidated Financial Statements), the three 
former executives relinquished all of their rights to 
certain deferred compensation, restricted stock units, 
MVE incentives, stock options and reimbursement of 
legal fees. The reversal of accruals related to the per-
formance of the financial asset portfolio was recorded 
in discontinued operations. Additionally, a portion of 
the $25 million settlement expense was allocated to 
discontinued operations. These transactions resulted in 
a net gain of $8.1 million, net of associated expenses 
($5.1 million after tax), on the settlement of litigation 
being recorded in discontinued operations in 2007.

There were no discontinued operations recorded  

in 2009 or 2008.

Debt and Debt Covenants 

On December 21, 2009, DPL purchased $52.4 million principal amount of DPL Capital Trust II 8.125% capital 
securities in a privately negotiated transaction. As part of this transaction, DPL paid a $3.7 million, or 7%, premium 
which was recognized as an expense in the fourth quarter of 2009 and recorded within interest expense on the 
Consolidated Statements of Results of Operations. 

On April 21, 2009, DP&L entered into a $100 million unsecured revolving credit agreement with a syndicated 

bank group. The agreement is for a 364-day term expiring on April 20, 2010. The facility contains one financial 
covenant: DP&L’s total debt to total capitalization ratio is not to exceed 0.65 to 1.00. As of December 31, 2009,

this covenant is met with a ratio of 0.40 to 1.00. As of 
December 31, 2009, there were no borrowings out-
standing under this facility. Fees associated with this 
credit facility were approximately $0.7 million in 2009.
On March 31, 2009, DPL paid $175 million of the 

8.00% Senior notes when the notes became due. 
On December 4, 2008, the OAQDA issued 
$100 million of collateralized, variable rate Revenue 
Refunding Bonds Series A and B due November 1, 
2040. In turn, DP&L borrowed these funds from the 
OAQDA. The payment of principal and interest on the 
bonds when due is backed by a standby letter of credit 
(LOC) issued by a syndicated bank group. This LOC 
facility, which was for an initial two-year period expiring 
in December 2010, is irrevocable, has no subjective 
acceleration clauses and also contains a provision that 
all outstanding amounts drawn on the facility are due 
upon the LOC’s expiration date. Since this LOC facility 
will expire in December 2010, at which point the bond-
holders could call the bonds, we have reflected these 
outstanding bonds as a current liability. Management 
will continue to monitor and evaluate market conditions 
over the next several months and make a determina-
tion to either seek a renewal of this standby letter of 
credit or to explore alternative financing arrangements. 
DP&L used $10 million of the proceeds from this bond 
issuance to finance its portion of the costs for acquir-
ing, constructing and installing certain solid waste 
disposal and air quality facilities at the Conesville gen-
eration station. The remaining $90 million was used to 
redeem the 2007 Series A Bonds as discussed in the 
next paragraph.

On November 15, 2007, the OAQDA issued $90 
million of collateralized, variable rate OAQDA Revenue 
Bonds, 2007 Series A due November 1, 2040. In turn, 
DP&L borrowed these funds from the OAQDA. The 
payment of principal and interest on the bonds when 
due was insured by an insurance policy issued by 
Financial Guaranty Insurance Company (FGIC).  
During the first quarter of 2008, all three credit rating 
agencies downgraded FGIC. These downgrades,  
as well as the downgrades of our major bond insurers, 
resulted in auction rate security bonds carrying  

substantially higher interest rates in succeeding auc-
tions and incurring failed auctions. On April 4, 2008, 
DP&L converted the 2007 Series A Bonds from Auction 
Rate Securities to Variable Rate Demand Notes. At that 
time, DP&L repurchased these notes out of the market 
and placed them with the Trustee to be held until the 
capital markets corrected. These notes were redeemed 
in December 2008.

On November 21, 2006, DP&L entered into 
a $220 million unsecured revolving credit agreement. 
This agreement has a five-year term that expires on 
November 21, 2011 and provides DP&L with the ability 
to increase the size of the facility by an additional $50 
million at any time. The facility contains one financial 
covenant: DP&L’s total debt to total capitalization ratio 
is not to exceed 0.65 to 1.00. As of December 31, 
2009, this covenant is met with a ratio of 0.40 to 1.00. 
DP&L had no outstanding borrowings under this credit 
facility at December 31, 2009. Fees associated with 
this credit facility were approximately $0.9 million  
in 2009 compared to $0.3 million in 2008. Changes  
in credit ratings, however, may affect fees and the 
applicable interest. This revolving credit agreement 
contains a $50 million letter of credit sublimit. As of 
December 31, 2009, DP&L had no outstanding letters 
of credit against the facility. DP&L has certain contrac-
tual agreements for the sale and purchase of power, 
fuel and related energy services that contain credit  
rating related clauses allowing the counter parties to 
seek additional surety under certain conditions. 
During the first quarter of 2006, the Ohio 

Department of Development (ODOD) awarded DP&L 
the ability to issue, through 2008, up to $200 million  
of qualified tax-exempt financing from the ODOD’s 
2005 volume cap carryforward. The PUCO approved 
DP&L’s application for this additional financing on 
July 26, 2006. The entire $200 million financing was 
used to partially fund the FGD capital projects. 

Substantially all property, plant and equipment  

of DP&L are subject to the lien of the mortgage 
securing DP&L’s First and Refunding Mortgage, dated 
as of October 1, 1935, with the Bank of New York  
as Trustee.

Accounting for Uncertainty in Income Taxes 

We apply the provisions of GAAP relating to the accounting for uncertainty in income taxes. A reconciliation of  
the beginning and ending amount of unrecognized tax benefits for DPL and DP&L is as follows:

Of the December 31, 2009 balance of unrecognized tax benefits, $21.6 million is due to uncertainty in the timing  
of deductibility offset by $2.3 million of unrecognized tax liabilities that would affect the effective tax rate.

We recognize interest and penalties related to unrecognized tax benefits in income taxes. The amount of  
interest and penalties accrued was a benefit of $0.1 million as of December 31, 2009 and an expense of less than 
$0.1 million as of December 31, 2008. The amount of interest and penalties recorded in the statements of results  
of operations for 2009 and 2008 was a benefit of $0.1 million and $9.0 million, respectively, and an expense of  
$4.1 million for 2007.

Following is a summary of the tax years open to examination by major tax jurisdiction: 

U.S. Federal – 2007 and forward 
State and Local – 2005 and forward 

None of the unrecognized tax benefits are expected to significantly increase or decrease within the next  
twelve months.

On February 13, 2006, we received correspondence from the ODT notifying us that the ODT had completed 
their examination and review of our Ohio Corporation Franchise Tax Returns for tax years 2002 through 2004 and 
that the final proposed audit adjustments resulted in a balance due of $90.8 million before interest and penalties. 
On June 27, 2008, we entered into a $42.0 million settlement agreement with the ODT resolving all outstanding 
audit issues and appeals, including uncertain tax positions for tax years 1998 through 2006. The $42 million  
payment was made to the ODT in July 2008. Due to this settlement agreement, the balance of our unrecognized 
state tax liabilities recorded at December 31, 2007, in the amount of $56.3 million, was reversed resulting in a 
recorded income tax benefit of $8.5 million, net of federal tax impact, in 2008.

9 Pension and Postretirement Benefits

DP&L sponsors a defined benefit plan for substantially 
all employees. For collective bargaining employees, 
the defined benefits are based on a specific dollar 
amount per year of service. For all other employees, 
the defined benefit plan is based primarily on com-
pensation and years of service. We fund pension plan 
benefits as accrued in accordance with the minimum 
funding requirements of the Employee Retirement 
Income Security Act of 1974 (ERISA). In addition, we 
have a Supplemental Executive Retirement Plan (SERP) 
for certain active and retired key executives. Benefits 
under this SERP have been frozen and no additional 
benefits can be earned. We also have unfunded liabili-
ties related to retirement benefits for certain active, 
terminated and retired key executives. 

On February 23, 2006, DPL’s Board of Directors 
approved a new compensation and benefits program 
that includes The DPL Inc. Supplemental Executive 
Defined Contribution Retirement Plan (SEDCRP) which 
replaces our SERP that was terminated as to new par-
ticipants in 2000. The Compensation Committee of the 
Board of Directors designates the eligible employees. 
Pursuant to the SEDCRP, we provide a supplemen-
tal retirement benefit to participants by crediting an 
account established for each participant in accordance 
with the Plan requirements. We designate as hypotheti-
cal investment funds under the SEDCRP one or more 
of the investment funds provided under The Dayton 
Power and Light Company Employee Savings Plan. 
Each participant may change his or her hypothetical 
investment fund selection at specified times. If a partic-

ipant does not elect a hypothetical investment fund(s), 
then we select the hypothetical investment fund(s) for 
such participant.

A participant shall become 100% vested in all 
amounts credited to his or her account upon the com-
pletion of five vesting years, as defined in The Dayton 
Power and Light Company Retirement Income Plan, or 
upon a change of control or the participant’s death or 
disability. If a participant’s employment is terminated, 
other than by death or disability, prior to such partici-
pant becoming 100% vested in his or her account, the 
account shall be forfeited as of the date of termination.
Qualified employees who retired prior to 1987  
and their dependents are eligible for health care and 
life insurance benefits, while qualified employees who 
retired after 1987 are eligible for life insurance benefits 
only. We have funded a portion of the union-eligible 
health benefits using a Voluntary Employee Beneficiary 
Association Trust. 

Regulatory assets and liabilities are recorded for 

the portion of the under- or over-funded obligations 
related to the transmission and distribution areas of our 
electric business and for the changes in the funded 
status of the plan that arise during the year that are 
not recognized as a component of net periodic benefit 
cost. These regulatory assets and liabilities represent 
the regulated portion that would otherwise be charged 
or credited to AOCI. We have historically recorded 
these costs on the accrual basis and this is how these 
costs have been historically recovered. This factor, 
combined with the historical precedents from the 
PUCO and FERC, make these costs probable of future 
rate recovery.

(a) For purposes of calculating the expected return on pension plan assets, under GAAP, the market-related value of assets (MRVA) is used.  
GAAP requires that the difference between actual plan asset returns and estimated plan asset returns be admitted into the MRVA equally  
over a period not to exceed five years. We use a methodology under which we admit the difference between actual and estimated asset returns  
in the MRVA equally over a three year period. The MRVA used in the 2009 calculation of expected return on pension plan assets was  
approximately $275 million.

On November 26, 2007, DP&L contributed $27.4 million in DPL common stock from its Master Trust assets 
to the Retirement Income Plan.

Our expected return on plan asset assumptions, used to determine benefit obligations, are based on  
historical long-term rates of return on investments, which use the widely accepted capital market principle  
that assets with higher volatility generate a greater return over the long run. Current market factors, such as  
inflation and interest rates, as well as asset diversification and portfolio rebalancing, are evaluated when  
long-term capital market assumptions are determined. Peer data and historical returns are reviewed to verify  
reasonableness and appropriateness. 

Our overall expected long-term rate of return on assets is approximately 8.50% for pension plan assets  
and approximately 6.00% for retiree benefit plan assets. This expected return is based primarily on historical 
returns and portfolio investment allocation. There can be no assurance of our ability to generate those rates  
of return in the future.

which represents a portfolio of top-quartile AA-rated bonds used to settle pension obligations and the Citigroup 
Pension Discount Curve. Peer data and historical returns were also reviewed to verify the reasonableness and

The Pension Protection Act (the Act) of 2006 
contained new requirements for our single employer 
defined benefit pension plan. In addition to establishing 
a 100% funding target for plan years beginning after 
December 31, 2008, the Act also limits some benefits if 
the funded status of pension plans drops below certain 
thresholds. Among other restrictions under the Act, if 
the funded status of a plan falls below a predetermined 
ratio which is 80% in 2010, lump-sum payments to new 
retirees are limited to 50% of amounts that otherwise 
would have been paid and new benefit improvements 
may not go into effect. For the 2009 plan year, the  
funded status of our defined benefit pension plan as  
calculated under the requirements of the Act was 
101.7% and is estimated to be 91.7% until the 2010 
status is certified in September 2010 for the 2010  
plan year. The Worker, Retiree, and Employer Recovery 
Act of 2008 (WRERA), which was signed into law  
on December 23, 2008, grants plan sponsors certain 
relief from funding requirements and benefit restrictions 
of the Act. 

Plan Assets 

Plan assets are invested using a total return investment 
approach whereby a mix of equity securities, debt 
securities and other investments are used to preserve 
asset values, diversify risk and achieve our target 

investment return benchmark. Investment strategies 
and asset allocations are based on careful consider-
ation of plan liabilities, the plan’s funded status and  
our financial condition. Investment performance  
and asset allocation are measured and monitored on 
an ongoing basis. 

Plan assets are managed in a balanced portfolio 

comprised of two major components: an equity portion 
and a fixed income portion. The expected role of  
Plan equity investments is to maximize the long-term 
real growth of Plan assets, while the role of fixed 
income investments is to generate current income,  
provide for more stable periodic returns and provide 
some protection against a prolonged decline in the 
market value of Plan equity investments. 

Long-term strategic asset allocation guidelines are 

determined by management and take into account  
the Plan’s long-term objectives as well as its short-term 
constraints. The target allocations for plan assets are 
30-80% for equity securities, 30-65% for fixed income 
securities, 0-10% for cash and 0-25% for alternative 
investments. Equity securities include U.S. and inter-
national equity, while fixed income securities include 
long-duration and high-yield bond funds and emerging 
market debt funds. Other types of investments include 
investments in hedge funds and private equity funds 
that follow several different strategies.

Debt is fair valued based on current public market prices for disclosure purposes only. Unrealized gains  
or losses are not recognized in the financial statements as debt is presented at amortized cost in the financial 
statements. The debt amounts include the current portion payable in the next twelve months and have  
maturities that range from 2010 to 2040.

Master Trust Assets

DP&L established a Master Trust to hold assets for the benefit of employees participating in employee benefit 
plans and these assets are not used for general operating purposes. These assets are primarily comprised  
of open-ended mutual funds and DPL common stock. The DPL common stock held by the DP&L Master Trust is 
eliminated in consolidation and is not reflected in DPL’s Consolidated Balance Sheets. The DPL common stock 
is valued using current public market prices, while the open-ended mutual funds are valued using the net asset 
value per unit. These investments are accounted for as available-for-sale securities and are recorded at fair  
value. Any unrealized gains or losses are recognized in AOCI until the securities are sold. 

DPL had $0.3 million ($0.2 million after tax) in unrealized gains and no unrealized losses on the Master

No unrealized gains or losses are expected to be transferred to earnings in 2010.

Transfer of Master Trust Assets to Pension 

On October 26, 2007, the Board of Directors approved a resolution permitting the transfer of 925,000 shares  
of DPL common stock from the DP&L Master Trust to The Dayton Power and Light Company Retirement 
Income Plan Trust (Pension). This transaction was completed on November 26, 2007, contributing shares of  
DPL common stock with a fair value of $27.4 million to the pension plan.

exclude DPL common stock which is valued using quoted market prices and not the NAV. Fair values estimated 
using the net asset value per unit are considered Level 2 inputs within the fair value hierarchy, unless they  
cannot be redeemed at the NAV on the reporting date. Investments that have restrictions on the redemption of  
the investments are Level 3 inputs. As of December 31, 2009, DPL did not have any investments for sale at a 
price different than the NAV.

Fair Value Hierarchy

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability  
(an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction 
between market participants on the measurement date. The fair value hierarchy requires an entity to maximize  
the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. These  
inputs are then categorized as Level 1 (quoted prices in active markets for identical assets or liabilities);  
Level 2 (observable inputs such as quoted prices for similar assets or liabilities or quoted prices in markets that  
are not active); or Level 3 (unobservable inputs). 

Valuations of assets and liabilities reflect the value of the instrument including the values associated with  
counterparty risk. We include our own credit risk and our counterparty’s credit risk in our calculation of fair value 
using the Global Corporate Cumulative Average Default Rates.

(a) DP&L holds DPL stock in the Master Trust that is eliminated in consolidation.

Level 1 inputs are used for DPL common stock held by the Master Trust and for derivative contracts such as 
heating oil futures. The fair value is determined by reference to quoted market prices and other relevant information 
generated by market transactions. Level 2 inputs are used to value derivatives such as financial transmission  
rights where the quoted prices are from a relatively inactive market; forward power contracts and forward NYMEX-
quality coal contracts which are traded on the OTC market but which are valued using prices on the NYMEX  
for similar contracts on the OTC market; and open-ended mutual funds that are in the Master Trust valued using  
the end of day NAV.

Non-recurring fair value measurements

The fair value of an ARO is estimated by discounting expected cash outflows to their present value at the initial 
recording of the liability. Cash outflows are based on the approximate future disposal cost as determined by  
market information, historical information or other management estimates. These inputs to the fair value of the 
AROs would be considered Level 3 inputs under the fair value hierarchy. We added a new ARO for a landfill and 
additional layers to our existing landfill and asbestos AROs in the amount of $2.7 million during 2009.

DPL had $45.3 million and $15.0 million in money market funds classified as cash and cash equivalents in 
its Consolidated Balance Sheets at December 31, 2009 and 2008, respectively. The money market funds have 
quoted prices that are generally equivalent to par.

11 Derivative Instruments and Hedging Activities

In the normal course of business, DPL and DP&L enter into various financial instruments, including derivative 
financial instruments. We use derivatives principally to manage the risk of changes in market prices for  
commodities. The derivatives that we use to economically hedge these risks are governed by our risk management 
policies for forward and futures contracts. Our net positions are continually assessed within our structured hedging 
programs to determine whether new or offsetting transactions are required. The objective of the hedging program 
is generally to mitigate financial risks while ensuring that we have adequate resources to meet our requirements. 
We monitor and value derivative positions monthly as part of our risk management processes. We use published 
sources for pricing when possible to mark positions to market. All of our derivative instruments are used for  
risk management purposes and are designated as a cash flow hedge or marked to market each reporting period.

At December 31, 2009, DP&L had the following outstanding derivative instruments:

Cash Flow Hedges

As part of our risk management processes, we identify the relationships between hedging instruments and  
hedged items, as well as the risk management objective and strategy for undertaking various hedge transactions. 
The MTM value of cash flow hedges as determined by current public market prices will continue to fluctuate with 
changes in market prices up to contract expiration. The effective portion of the hedging transaction is recognized 
in AOCI and transferred to earnings when the hedged forecasted transaction takes place or when the hedged 
forecasted transaction is probable of not occurring. The ineffective portion of the cash flow hedge is recognized in 
earnings in the current period. All risk components were taken into account to determine the hedge effectiveness  
of the cash flow hedges.

We currently use cash flow hedging with forward power contracts and in 2003 we entered into an interest  
rate swap which was settled that same year. Approximately $2.1 million ($1.4 million net of tax) of accumulated 
losses in AOCI related to the above mentioned power hedges are expected to be reclassified to earnings over  
the next twelve months. The balance of the remaining deferred gain from the interest rate swap in AOCI is being  
amortized into earnings over the life of the related bonds. Approximately $2.5 million ($1.6 million net of tax) of 
accumulated gains in AOCI related to the above referenced interest rate hedge are expected to be reclassified to 
earnings over the next twelve months. As of December 31, 2009, the maximum length of time that we are hedging 
our exposure to variability in future cash flows related to forecasted transactions is 23 months and 106 months  
for the forward power positions and the interest rate hedge, respectively. 

The following table provides information concerning gains or losses recognized in AOCI for the cash  

flow hedges:

Mark to Market 

Certain derivative contracts are entered into on a regular basis as part of our risk management program but do 
not qualify for hedge accounting or the normal purchase and sales exceptions under FASC 815. Accordingly, such 
contracts are recorded at fair value with changes in the fair value charged or credited to the statements of results 
of operations in the period in which the change occurred. This is commonly referred to as “MTM” accounting. 
Contracts we enter into as part of our risk management program may be settled financially, by physical delivery or 
net settled with the counterparty. We currently MTM Financial Transmission Rights (FTRs), heating oil futures and 
forward NYMEX-quality coal contracts.

DP&L enters into coal contracts from time to time to supply its generating plants. We perform a quarterly 
evaluation of the different coal markets to determine if these coal contracts are considered derivative instruments 
under FASC 815. DP&L has concluded that NYMEX and NYMEX look-a-like coal contracts are considered 
derivative instruments because they have been determined to be readily convertible to cash under FASC 815.
Certain qualifying derivative instruments have been designated as normal purchases or normal sales  
contracts, as provided in FASC 815. Derivative contracts that have been designated as normal purchases or  
normal sales under FASC 815 are not subject to MTM accounting treatment and are recognized in the statements 
of results of operations on an accrual basis.

Regulatory Assets and Liabilities

Under FASC 980, “Regulated Operations,” if a cost is probable of recovery in future rates, it should be deferred 
as a regulatory asset. If a gain is probable of being returned to customers, it should be deferred as a regulatory 
liability. Portions of the derivative contracts that are marked to market each reporting period and are related to the 
retail portion of DP&L’s load requirements are included as part of the fuel factor approved by the PUCO beginning 
January 1, 2010. Therefore, the Ohio jurisdictional retail portion of the heating oil futures and the NYMEX-quality

coal contracts are deferred as a regulatory asset or liability until the contracts settle. If these unrealized  
gains and losses are no longer deemed to be probable of recovery through our rates, they will be reclassified  
into earnings in the period such determination is made.

Certain of our OTC commodity derivative contracts are under master netting agreements that contain provisions 
that require our debt to maintain an investment grade credit rating from credit rating agencies. If our debt were  
to fall below investment grade, we would be in violation of these provisions, and the counterparties to the derivative 
instruments could request immediate payment or demand immediate and ongoing full overnight collateralization  
of the MTM loss. The aggregate fair value of all derivative instruments that are in a MTM loss position at December 
31, 2009, is $4.7 million. This amount is offset by $1.2 million in a broker margin account which offsets our loss 
positions on the NYMEX Clearport traded heating oil and coal contracts. If our debt were to fall below investment 
grade, we would have to post collateral for the remaining $3.5 million.

12 Stock-Based Compensation

In April 2006, DPL’s shareholders approved The DPL Inc. Equity and Performance Incentive Plan (the EPIP) 
which became immediately effective and will remain in effect for a term of ten years, unless terminated sooner in 
accordance with its terms. The Compensation Committee of the Board of Directors will designate the employees 
and directors eligible to participate in the EPIP and the times and types of awards to be granted. Under the  
EPIP, the Compensation Committee may grant equity-based compensation in the form of stock options, stock 
appreciation rights, restricted stock, restricted stock units, performance shares and units, and other stock-based 
awards. Awards may be subject to the achievement of certain management objectives. In addition, the EPIP  
provides, upon recommendation of the Chief Executive Officer and Chairman of the Board, for a grant of a  
special equity award to recognize outstanding performance. A total of 4,500,000 shares of DPL common stock 
were reserved for issuance under the EPIP. 

The following table summarizes share-based compensation expense recorded at DPL and DP&L:

Share-based awards issued in DPL’s common stock will be distributed from treasury stock. DPL has 
sufficient treasury stock to satisfy all outstanding share-based awards.

Determining Fair Value

Valuation and Amortization Method – We estimate the fair value of stock options and RSUs using a Black-
Scholes-Merton model; performance shares are valued using a Monte Carlo simulation; restricted shares are  
valued at the closing market price on the day of grant and the Directors’ RSUs are valued at the closing market 
price on the day prior to the grant date. We amortize the fair value of all awards on a straight-line basis over  
the requisite service periods, which are generally the vesting periods. 

Expected Volatility – Our expected volatility assumptions are based on the historical volatility of DPL common 
stock. The volatility range captures the high and low volatility values for each award granted based on its  
specific terms. 

Expected Life – The expected life assumption represents the estimated period of time from grant until exercise 
and reflects historical employee exercise patterns. 

Risk-Free Interest Rate – The risk-free interest rate for the expected term of the award is based on the corre-
sponding yield curve in effect at the time of the valuation for U.S. Treasury bonds having the same term as the 
expected life of the award, i.e., a five year bond rate is used for valuing an award with a five year expected life. 

Expected Dividend Yield – The expected dividend yield is based on DPL’s current dividend rate, adjusted as 
necessary to capture anticipated dividend changes and the 12 month average DPL common stock price. 

Expected Forfeitures – The forfeiture rate used to calculate compensation expense is based on DPL’s historical 
experience, adjusted as necessary to reflect special circumstances.

Stock Options

In 2000, DPL’s Board of Directors adopted and DPL’s shareholders approved The DPL Inc. Stock Option Plan. 
On April 26, 2006, DPL’s shareholders approved The DPL Inc. 2006 Equity and Performance Incentive Plan (EPIP). 
With the approval of the EPIP, no new awards will be granted under The DPL Inc. Stock Option Plan, but shares 
relating to awards that are forfeited or terminated under The DPL Inc. Stock Option Plan may be granted under the 
EPIP. As of December 31, 2009, there were no unvested stock options.

No options were granted during 2007, 2008 or 2009.

Restricted Stock Units (RSUs)

RSUs were granted to certain key employees prior to 2001. As a result of the settlement of the former  
executive litigation, all disputed RSUs (1.3 million) were forfeited by three former executives (see Note 17  
of Notes to Consolidated Financial Statements). There were 3,311 RSUs outstanding as of December 31, 2009, 
none of which has vested. The non-vested RSUs will be paid in cash upon vesting in 2010. Non-vested  
RSUs are valued quarterly at fair value using the Black-Scholes-Merton model to determine the amount of  
compensation expense to be recognized. Non-vested RSUs do not earn dividends.

Summarized RSU activity was as follows:

Compensation expense is recognized each quarter based on the change in the market price of DPL 
common stock.

As of December 31, 2009, 2008 and 2007, liabilities recorded for outstanding RSUs were $0.1 million,  
$0.2 million and $0.6 million, respectively, which are included in Other deferred credits on the balance sheets.

Under the EPIP, the Board adopted a Long-Term Incentive Plan (LTIP) under which DPL will grant a targeted 
number of performance shares of common stock to executives. Grants under the LTIP will be awarded  
based on a Total Shareholder Return Relative to Peers performance. No performance shares will be earned in  
a performance period if the three-year Total Shareholder Return Relative to Peers is below the threshold of the  
40th percentile. Further, the LTIP awards will be capped at 200% of the target number of performance shares,  
if the Total Shareholder Return Relative to Peers is at or above the threshold of the 90th percentile. The Total 
Shareholder Return Relative to Peers is considered a market condition under FASC 718. There is a three year  
requisite service period for each portion of the performance shares.

Under the EPIP, the Board granted shares of DPL Restricted Shares to various executives. The Restricted 
Shares are registered in the executive’s name, carry full voting privileges, receive dividends as declared and  
paid on all DPL common stock and vest after a specified service period. 

In July 2008, the Board of Directors granted compensation awards to a select group of management  

employees. The management restricted stock awards have a three-year requisite service period, carry full voting 
privileges and receive dividends as declared and paid on all DPL common stock. 

On September 17, 2009, the DPL Board of Directors approved a two-part equity compensation award 
under DPL’s 2006 Equity and Performance Incentive Plan for certain of DPL’s executive officers. The first part is 
a restricted share grant and the second part is a matching restricted share grant. A total of 90,036 restricted  
shares were granted on September 17, 2009 as part of the restricted share grant. These restricted shares generally 
vest after five years if the participant remains continuously employed with DPL or a subsidiary and if the year over 
year average basic EPS has increased by at least 1% per year from 2009 - 2013. Under the matching restricted 
share grant, participants will have a three-year period from the date of plan implementation during which they  
may purchase DPL common stock equal in value to up to two times their base salary. DPL will match the shares 
purchased with another grant of restricted stock (matching restricted share grant). The percentage match by  
DPL is detailed in the table below. The matching restricted share grant will generally vest over a three year period 
if the participant continues to hold the originally purchased shares and remains continuously employed with DPL 
or a subsidiary. The restricted shares are registered in the executive’s name, carry full voting privileges and receive 
dividends as declared and paid on all DPL common stock.

The matching criteria are:

 Value (Cost Basis) of Shares Purchased  
as a % of 2009 Base Salary 

Company % Match of 
Shares Purchased

<25% 
25% to <50% 
50% to <100%

DPL Inc.  103

Restricted stock can only be awarded in DPL common stock.

Non-Employee Director Restricted Stock Units

Under the EPIP, as part of their annual compensation for service to DPL and DP&L, each non-employee 
Director receives a retainer in RSUs on the date of the annual meeting of shareholders. The RSUs will become  
non-forfeitable on April 15 of the following year. All of the RSUs become non-forfeitable in the event of death,  
disability, or change in control; but if the Director resigns or retires prior to the April 15 vesting date, the vested 
shares will be distributed on a pro rata basis. The RSUs accrue quarterly dividends in the form of additional  
RSUs. Upon vesting, the RSUs will become exercisable and will be distributed in DPL common stock, unless the 
Director chooses to defer receipt of the shares until a later date. The RSUs are valued at the closing stock price  
n the day prior to the grant and the compensation expense is recognized evenly over the vesting period.

The DP&L preferred stock may be redeemed at DP&L’s option as determined by its Board of Directors at the 
per-share redemption prices indicated above, plus cumulative accrued dividends. In addition, DP&L’s Amended 
Articles of Incorporation contain provisions that permit preferred stockholders to elect members of the 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. Since this potential redemption-triggering event is not solely  
within the control of DP&L, the preferred stock is presented on the Balance Sheets as “Redeemable Preferred 
Stock” in a manner consistent with temporary equity.

As long as any DP&L preferred stock is outstand-

ing, DP&L’s Amended Articles of Incorporation also 
contain provisions restricting the payment of cash divi-
dends on any of its common stock if, after giving effect 
to such dividend, the aggregate of all such dividends 
distributed subsequent to December 31, 1946 exceeds 
the net income of DP&L available for dividends on its 
common stock subsequent to December 31, 1946,  
plus $1.2 million. This dividend restriction has histori-
cally not impacted DP&L’s ability to pay cash divi-
dends and, as of December 31, 2009, DP&L’s retained 
earnings of $640.3 million were all available for com-
mon stock dividends payable to DPL. We do not 
expect this restriction to have an effect on the payment 
of cash dividends in the future. DPL records dividends 
on preferred stock of DP&L within Interest expense on 
the Statements of Results of Operations. 

14 Common Shareholders’ Equity

DPL has 250,000,000 authorized common 
shares, of which 118,966,767 are outstanding at 
December 31, 2009. 

Dividend Reinvestment Plan

On March 1, 2009, DPL introduced a new direct stock 
purchase and dividend reinvestment plan. The plan 
provides both registered shareholders and new inves-
tors with the ability to purchase shares and also to 
reinvest their dividends. This plan is administered by 
Computershare Trust Company, N.A., and not by DPL.

Shareholder Rights Plan

In September 2001, DPL’s Board of Directors renewed 
its Shareholder Rights Plan, attaching one right to  
each common share outstanding at the close of busi-
ness on December 13, 2001. The rights separate from 
the common shares and become exercisable at the 
exercise price of $130 per right in the event of certain 
attempted business combinations. The renewed plan 
expires on December 31, 2011. 

Warrants

In February 2000, DPL entered into a series of recapi-
talization transactions which included the issuance of 
31.6 million warrants for an aggregate purchase price 
of $50 million. The warrants are exercisable, in whole 
or in part, for common shares at any time during the 
twelve-year period commencing on March 13, 2000. 

Each warrant is exercisable for one common share, 
subject to anti-dilution adjustments (e.g., stock split, 
stock dividend) at an exercise price of $21.00 per 
common share.

In addition, in the event of a declaration, issuance 

or consummation of any dividend, spin-off or other 
distribution or similar transaction by DPL of the capital 
stock of any of its subsidiaries, additional warrants of 
such subsidiary will be issued to the warrant holder so 
that after the transaction, the warrant holder will have 
the same interest in the fully diluted number of com-
mon shares of such subsidiary the warrant holder had 
in DPL immediately prior to such transaction.

Pursuant to the warrant agreement, DPL has 
authorized common shares sufficient to provide for the 
exercise in full of all outstanding warrants. 

The table below details the net change during 

2009 of DPL’s outstanding warrants:

The warrants repurchased were cancelled by DPL on 
the dates they were repurchased. As a result of the 
warrants exercised under both cash and cashless 
provisions, DPL issued a total of 5.0 million shares of 
common stock from treasury stock and in turn received 
total cash proceeds of $77.7 million. DPL used a por-
tion of the proceeds to repurchase warrants directly 
from holders and the remaining proceeds were used 
to repurchase shares under its Stock Repurchase 
Program discussed below. 

Stock Repurchase Program

On October 28, 2009, the DPL Board of Directors 
approved a Stock Repurchase Program under which 
DPL may use proceeds from the exercise of warrants 
to repurchase warrants or its common stock from time 
to time in the open market, through private transac-
tions or otherwise. The Stock Repurchase Program 
will run through June 30, 2012, which is three months 
after the end of the warrant exercise period. Under the 
Stock Repurchase Program, DPL repurchased a total 
of 2.4 million shares at an average per share price of 
$26.96 during the quarter ended December 31, 2009. 
At December 31, 2009, the amount still available that 

DPL Inc.  107

 
could be used to repurchase stock under the Stock 
Repurchase Program is approximately $3.9 million but 
could be higher if additional warrants are exercised for 
cash in the future.

ESOP

During October 1992, our Board of Directors approved 
the formation of a Company-sponsored ESOP to fund 
matching contributions to DP&L’s 401(k) retirement 
savings plan and certain other payments to eligible full-
time employees. This leveraged ESOP is funded by an 
exempt loan, which is secured by the ESOP shares. As 
debt service payments are made on the loan, shares 
are released on a pro rata basis. ESOP shares used 
to fund matching contributions to DP&L’s 401(k) vest 
after three years of service; other compensation shares 
awarded vest immediately.

In general, participants are eligible for lump sum 
payments upon termination of their employment and 
the submission and subsequent approval of an appli-
cation for benefits. Earlier distributions can occur for 
a Qualified Domestic Relations Order or for death. 
Otherwise, distribution must occur within 60 days after 
the plan year in which the later of one of the following 
events occur: 65th birthday, 10th anniversary of par-
ticipation, or termination of employment. Participants 
are allowed to take distributions during employment if 
older than 59½ and/or for a hardship as defined in the 
Plan document. Additionally, participants may elect 
on a quarterly basis to diversify their vested ESOP 
shares into DP&L’s 401(k) retirement savings plan. 
Distributions are made in cash unless the participant 
requests the distribution be made in stock. A repur-
chase obligation exists for vested shares held by the 
ESOP if they cannot be sold in the open market. The 
fair value of shares subject to the repurchase obligation 
at December 31, 2009 and 2008 was approximately 
$57.6 million and $42.4 million, respectively.

In 1992, the Plan entered into a $90 million loan 
agreement with DPL in order to purchase shares of 
DPL common stock in the open market. The term loan 

agreement provided for principal and interest on the 
loan to be paid prior to October 9, 2007, with the right 
to extend the loan for an additional ten years. In 2007, 
the maturity date was extended to October 7, 2017. 
Effective January 1, 2009, the interest on the loan was 
amended to a fixed rate of 2.06%, payable annually. 
Dividends received by the ESOP for unallocated shares 
are used to repay the principal and interest on the 
ESOP loan to DPL. Dividends on the allocated shares 
are charged to retained earnings.

The ESOP used the full amount of the loan to 
purchase 4.7 million shares of DPL common stock in 
the open market. As a result of the 1997 stock split, 
the ESOP held 7.1 million shares of DPL common 
stock. The cost of shares held by the ESOP and not 
yet released is reported as a reduction of Common 
shareholders’ equity. At December 31, 2009, Common 
shareholders’ equity reflects the cost of 2.8 million 
unreleased shares held in suspense by the DPL Inc. 
Employee Stock Ownership Trust. The fair value of the 
2.8 million ESOP shares held in suspense at December 
31, 2009 was $77.5 million. When shares are com-
mitted to be released from the ESOP, compensation 
expense is recorded based on the fair value of the 
shares committed to be released, with a corresponding 
credit to our equity. Compensation expense associ-
ated with the ESOP, which is based on the fair value 
of the shares committed to be released for allocation, 
amounted to $4.0 million in 2009, $1.5 million in 2008 
and $9.0 million in 2007. 

For purposes of EPS computations and in accor-

dance with GAAP, we treat ESOP shares as out-
standing if they have been allocated to participants, 
released or have been committed to be released. As of 
December 31, 2009, the ESOP has 4.2 million shares 
allocated to participants with an additional 21 thousand 
shares which have been released but unallocated to 
participants. ESOP cumulative shares outstanding for 
the calculation of EPS were 4.2 million in 2009, 4.0 mil-
lion in 2008 and 3.9 million in 2007.

15 Comprehensive Income (Loss)

Comprehensive income (loss) is defined as the change in equity (net assets) of a business entity during a period 
from transactions and other events and circumstances from non-owner sources. It includes all changes in equity 
during a period except those resulting from investments by owners and distributions to owners. Comprehensive 
income (loss) has two components: Net income (loss) and Other comprehensive income (loss). 

The following table provides the tax effects allocated to each component of Other comprehensive income

Basic EPS is based on the weighted-average number of DPL common shares outstanding during the year. 
Diluted EPS is based on the weighted-average number of DPL common and common-equivalent shares 
outstanding during the year, except in periods where the inclusion of such common-equivalent shares  
is anti-dilutive. Excluded from outstanding shares for these weighted-average computations are shares held  
by DP&L’s Master Trust Plan for deferred compensation and unreleased shares held by DPL’s ESOP.

The common-equivalent shares excluded from the calculation of diluted EPS, because they were anti- 
dilutive, were not material for all the periods ended December 31, 2009, 2008 and 2007. These shares may  
be dilutive in the future.

17 Executive Litigation

18 Insurance Recovery

On May 21, 2007, we settled litigation with three  
former executives. As part of this settlement, the three 
former executives relinquished and dismissed all their 
claims including those related to certain deferred com-
pensation, RSUs, MVE incentives, stock options and 
legal fees. The RSUs and stock options relinquished 
and forfeited were 1.3 million and 3.6 million, respec-
tively. Prior to the settlement date, we had accrued 
obligations of $64.2 million. Included in these amounts 
was $3.1 million associated with the forfeiture of stock 
options. In exchange for our payment of $25 million 
and the relinquishment by the former executives of cer-
tain contested compensation discussed above, all of 
these claims by all parties were settled and released.

DPL
As a result of this settlement, during 2007, DPL real-
ized a net pre-tax gain in continuing and discontinued  
operations of approximately $31.0 million and $8.2 mil-
lion, respectively. The net gain is comprised of the  
reversal of the $64.2 million of accrued obligations less 
the $25 million settlement. The obligations related  
to the discontinued operations were associated with 
the management of DPL’s financial asset portfolio, 
which was conducted in our MVE subsidiary. The MVE 
operations were discontinued in 2005 with the sale  
of the financial asset portfolio. The $25 million settle-
ment expense was allocated between continuing and  
discontinued operations based on the proportionate 
share of the obligations of each. 

DP&L
As a result of this settlement during 2007, DP&L 
realized a net pre-tax gain in continuing operations  
of $35.3 million. Accrued obligations associated with  
the former executives’ litigation were recorded by 
DP&L since the obligations were associated with our 
non-qualified benefit plans. DP&L had no ownership 
of DPL’s discontinued financial asset portfolio 
business, therefore these liabilities were reversed  
and DP&L’s net pre-tax gain was recorded within 
continuing operations. 

The $25 million settlement was funded from the 
sale of financial assets held in DP&L’s Master Trust 
Plan for deferred compensation. As part of this transac-
tion, during the second quarter ended June 30, 2007,  
DPL and DP&L recorded a $3.2 million realized gain 
which was reflected in investment income.

On April 30, 2007, DP&L executed a settlement 
agreement for $14.5 million with one of our insurers, 
Associated Electric & Gas Insurance Services (AEGIS), 
under a fiduciary liability policy to recoup a portion of 
legal fees associated with our litigation against three 
former executives. This was recorded as a reduction to 
operation and maintenance expense during 2007. 

On May 16, 2007, DPL filed a claim with Energy 

Insurance Mutual (EIM) to recoup legal expenses 
associated with our litigation against certain former 
executives. Arbitration on that claim occurred on May 
13, 2009. The arbitration panel issued a ruling in Phase 
1 of the arbitration on September 25, 2009, finding 
that most of the claims involving the former execu-
tives were covered. In accordance with GAAP, DPL 
recorded expenses totaling $7.5 million in 2008 but has 
not recorded any assets for possible recovery of these 
expenses. The matter is pending.

19 Contractual Obligations, Commercial 
Commitments and Contingencies

DPL – Guarantees 
In the normal course of business, DPL enters into vari-
ous agreements with its wholly-owned subsidiaries, 
DPLE and DPLER, providing financial or performance 
assurance to third parties. These agreements are 
entered into primarily to support or enhance the credit-
worthiness otherwise attributed to DPLE and DPLER on 
a stand-alone basis, thereby facilitating the extension 
of sufficient credit to accomplish DPLE’s and DPLER’s 
intended commercial purposes. 

At December 31, 2009, DPL had $51 million of 

guarantees to third parties for future financial or  
performance assurance under such agreements, on 
behalf of DPLE and DPLER. The guarantee arrange-
ments entered into by DPL with these third parties 
cover all present and future obligations of DPLE and 
DPLER to such beneficiaries and are terminable at any 
time by DPL upon written notice to the beneficiaries. 
The carrying amount of obligations for commercial 
transactions covered by these guarantees and record-
ed in our Consolidated Balance Sheets was $0.6  
million and $1.6 million at December 31, 2009 and 
2008, respectively. 

DPL Inc.  111

 
In two separate transactions in November and December 2006, DPL also agreed to be a guarantor of the 
obligations of DPLE regarding the sale, in April 2007, of the Darby Electric Peaking Station to American  
Electric Power and the sale of the Greenville Electric Peaking Station to Buckeye Electric Power, Inc. In both  
cases, DPL agreed to guarantee the obligations of DPLE over a multiple-year period as follows:

  2009

$  7.4

$  7.7

$  3.7

To date, neither DPL nor DP&L have incurred any losses related to the guarantees of DPLE’s obligations and 
we believe it is remote that either DPL or DP&L would be required to perform or incur any losses in the future 
associated with any of the above guarantees of DPLE’s obligations.

DP&L – Equity Ownership Interest 

DP&L owns a 4.9% equity ownership interest in an electric generation company which is recorded using the 
cost method of accounting under GAAP. As of December 31, 2009, DP&L could be responsible for the repayment 
of 4.9%, or $54.4 million, of a $1,110 million debt obligation that matures in 2026. This would only happen if this 
electric generation company defaulted on its debt payments. As of December 31, 2009, we have no knowledge  
of such a default.

Contractual Obligations and Commercial Commitments

We enter into various contractual obligations and other commercial commitments that may affect the liquidity  
of our operations. At December 31, 2009, these include:

prevailing at December 31, 2009.

Pension and postretirement payments:
As of December 31, 2009, DPL, through its principal 
subsidiary DP&L, had estimated future benefit pay-
ments as outlined in Note 9 of Notes to Consolidated 
Financial Statements. These estimated future benefit 
payments are projected through 2019.

subsidiary DP&L, had several immaterial operating 
leases with various terms and expiration dates. 

Coal contracts:
DPL, through its principal subsidiary DP&L, has 
entered into various long-term coal contracts to  
supply the coal requirements for the generating plants 
it operates. Some contract prices are subject to  
periodic adjustment and have features that limit price 
escalation in any given year. 

Limestone contracts:
DPL, through its principal subsidiary DP&L, has 
entered into various limestone contracts to supply  
limestone used in the operation of FGD equipment at 
its generating facilities. 

Purchase orders and other contractual obligations:
As of December 31, 2009, DPL and DP&L had various 
other contractual obligations including non-cancelable 
contracts to purchase goods and services with various 
terms and expiration dates.

Reserve for uncertain tax positions:
Due to the uncertainty regarding the timing of future 
cash outflows associated with our unrecognized  
tax benefits of $19.3 million, we are unable to make  
a reliable estimate of the periods of cash settlement 
with the respective tax authorities and have not  
included such amounts in the contractual obligations 
table above. 

Contingencies

In the normal course of business, we are subject to 
various lawsuits, actions, proceedings, claims and 
other matters asserted under laws and regulations. 
We believe the amounts provided in our Consolidated 

Financial Statements, as prescribed by GAAP, are 
adequate in light of the probable and estimable con-
tingencies. However, there can be no assurances that 
the actual amounts required to satisfy alleged liabilities 
from various legal proceedings, claims, tax examina-
tions, and other matters, including the matters dis-
cussed below, and to comply with applicable laws and 
regulations, will not exceed the amounts reflected in 
our Consolidated Financial Statements. As such, costs, 
if any, that may be incurred in excess of those amounts 
provided as of December 31, 2009, cannot be reason-
ably determined.

Governmental and Regulatory Inquiries 

On March 10, 2004, DPL’s and DP&L’s Corporate 
Controller sent a memorandum (the Memorandum) to 
the Chairman of the Audit Committee of our Board of 
Directors. The Memorandum expressed the Corporate 
Controller’s “concerns, perspectives and viewpoints” 
regarding financial reporting and governance issues 
within DPL and DP&L. In response, the Board initiated 
an internal investigation whose findings and recom-
mendations led to corrective action taken regarding 
internal controls, process issues and the tone at the top.
On May 28, 2004, the U.S. Attorney’s Office for 

the Southern District of Ohio, assisted by the Federal 
Bureau of Investigation, notified DPL and DP&L that it 
had initiated an inquiry involving matters connected to 
our internal investigation. This inquiry remains pending.
On or about June 24, 2004, the SEC commenced 

a formal investigation into the issues raised by the 
Memorandum. This investigation remains pending.

Environmental Matters 

DPL, DP&L and our subsidiaries’ facilities and 
operations are subject to a wide range of environmen-
tal regulations and laws by federal, state and local 
authorities. As well as imposing continuing compliance 
obligations, these laws and regulations authorize  
the imposition of substantial penalties for noncompli-
ance, including fines, injunctive relief and other  
sanctions. In the normal course of business, we have 
investigatory and remedial activities underway at these 
facilities to comply, or to determine compliance, with 
such regulations. We record liabilities for losses that 
are probable of occurring and can be reasonably esti-
mated. DPL, through its wholly owned captive insur-
ance subsidiary MVIC, has an actuarially calculated 
reserve of $1.2 million for environmental matters. We 
evaluate the potential liability related to probable losses 
quarterly and may revise our estimates. Such revisions 
in the estimates of the potential liabilities could have 
a material effect on our results of operations, financial 
position or cash flows.

Air Quality 

In 1990, the federal government amended the CAA  
to further regulate air pollution. Under the law, the  
USEPA sets limits on how much of a pollutant can be in 
the air anywhere in the United States. The CAA allows 
individual states to have stronger pollution controls, but 
states are not allowed to have weaker pollution controls 
than those set for the whole country. The CAA has  
a material effect on our operations and such effects  
are detailed below with respect to certain programs 
under the CAA. 

On October 27, 2003, the USEPA published final 
rules regarding the equipment replacement provision 
(ERP) of the routine maintenance, repair and replace-
ment (RMRR) exclusion of the CAA. Activities at power 
plants that fall within the scope of the RMRR exclu-
sion do not trigger new source review requirements, 
including the imposition of stricter emission limits. 
On December 24, 2003, the United States Court of 
Appeals for the D.C. Circuit stayed the effective date 
of the rule pending its decision on the merits of the 
lawsuits filed by numerous states and environmental 
organizations challenging the final rules. On June 
6, 2005, the USEPA issued its final response on the 
reconsideration of the ERP exclusion. The USEPA clari-
fied its position, but did not change any aspect of the 
2003 final rules. This decision was appealed and the 
D.C. Circuit vacated the final rules on March 17, 2006. 
The scope of the RMRR exclusion remains uncertain 
due to this action by the D.C. Circuit, as well as mul-
tiple litigations not directly involving us where courts 
are defining the scope of the exception with respect to 
the specific facts and circumstances of the particular 
power plants and activities before the courts. While we 
believe that we have not engaged in any activities with 
respect to our existing power plants that would trig-
ger the new source review requirements, if new source 
review requirements were imposed on any of DP&L’s 
existing power plants, the results could be materially 
adverse to us.

The USEPA issued a proposed rule on October 
20, 2005 concerning the test for measuring whether 
modifications to electric generating units should trigger 
application of New Source Review (NSR) standards 
under the CAA. A supplemental rule was also pro-
posed on May 8, 2007 to include additional options for 
determining if there is an emissions increase when an 
existing electric generating unit makes a physical or 
operational change. The rule was challenged by envi-
ronmental organizations and has not been finalized. 
While we cannot at this time predict the outcome of this 
rulemaking, any finalized rules could materially affect 
our operations.

On December 17, 2003, the USEPA proposed 

the Interstate Air Quality Rule (IAQR) designed to 
reduce and permanently cap SO2 and NOx emissions 
from electric utilities. The proposed IAQR focused on 
states, including Ohio, whose power plant emissions 
are believed to be significantly contributing to fine 
particle and ozone pollution in other downwind states 
in the eastern United States. On June 10, 2004, the 
USEPA issued a supplemental proposal to the IAQR, 
now renamed the CAIR. The final rules were signed on 
March 10, 2005 and were published on May 12, 2005. 
CAIR created an interstate trading program for annual 
NOx emission allowances and made modifications to 
an existing trading program for SO2. On August 24, 
2005, the USEPA proposed additional revisions to the 
CAIR. On July 11, 2008, the U.S. Court of Appeals for 
the District of Columbia Circuit issued a decision to 
vacate the USEPA’s CAIR and its associated Federal 
Implementation Plan and remanded to the USEPA with 
instructions to issue new regulations that conformed 
with the procedural and substantive requirements of 
the CAA. The Court’s decision, in part, invalidated the 
new NOx annual emission allowance trading program 
and the modifications to the SO2 emission trading 
program established by the March 10, 2005 rules, 
and created uncertainty regarding future NOx and 
SO2 emission reduction requirements and their timing. 
The USEPA and a group representing utilities filed a 
request on September 24, 2008 for a rehearing before 
the entire Court. On December 23, 2008, the U.S. 
Court of Appeals issued an order on reconsideration 
that permits CAIR to remain in effect until the USEPA 
issues new regulations that would conform to the CAA 
requirements and the Court’s July 11, 2008 decision.  
In January 2010, the Court ordered the USEPA to file  
a response to a Petition for Mandamus filed by par-
ties in the original case who are now seeking a Court 
order to require the USEPA to issue new regulations by 
March 1, 2010. We are currently unable to predict the 
outcome of this Petition or the timing or impact of any 
new regulations relating to CAIR. CAIR has and will 
continue to have a material effect on our operations.

In 2007, the Ohio EPA revised their State 

Implementation Plan (SIP) to incorporate a CAIR pro-
gram consistent with the IAQR. The Ohio EPA had 
received partial approval from the USEPA and had 
been awaiting full program approval from the USEPA 
when the U.S. Court of Appeals issued its July 11,  
2008 decision. As a result of the December 23, 2008 
order, the Ohio EPA proposed revised rules on  
May 11, 2009, which were finalized on July 15, 2009.  
On September 25, 2009, the USEPA issued a full SIP 
approval for the Ohio CAIR program. We do not  
expect that full SIP approval of the Ohio CAIR program 
will have a significant impact on operations.

In the fourth quarter of 2007, DP&L began a pro-
gram for selling excess emission allowances, including 
annual NOx emission allowances and SO2 emission 
allowances that were the subject of CAIR trading pro-
grams. In subsequent quarters, DP&L recognized 
gains from the sale of excess emission allowances to 
third parties. The court’s CAIR decision affected the 
trading market for excess allowances and impacted 
DP&L’s program for selling additional excess allow-
ances in 2008. Although in January 2009 we resumed 
selling excess allowances due to the revival of the trad-
ing market, the long-term impact of the court’s deci-
sion, and of the actions the USEPA or others will take in 
response to this decision, is not fully known at this time 
and could have an adverse effect on us. 

On January 30, 2004, the USEPA published its  

proposal to restrict mercury and other air toxins from 
coal-fired and oil-fired utility plants. The USEPA  
“de-listed” mercury as a hazardous air pollutant from 
coal-fired and oil-fired utility plants and, instead,  
proposed a cap-and-trade approach to regulate the 
total amount of mercury emissions allowed from such 
sources. The final Clean Air Mercury Rule (CAMR)  
was signed March 15, 2005 and was published on 
May 18, 2005. On March 29, 2005, nine states sued 
the USEPA, opposing the cap-and-trade regulatory 
approach taken by the USEPA. In 2007, the Ohio EPA 
adopted rules implementing the CAMR program. On 
February 8, 2008, the U.S. Court of Appeals for the 
District of Columbia Circuit struck down the USEPA  
regulations, finding that the USEPA had not complied 
with statutory requirements applicable to “de-listing” 
a hazardous air pollutant and that a cap-and-trade 
approach was not authorized by law for “listed” haz-
ardous air pollutants. A request for rehearing before 
the entire Court of Appeals was denied and a peti-
tion for review before the U.S. Supreme Court was 
filed on October 17, 2008. On February 23, 2009, the 
U.S. Supreme Court denied the petition. The USEPA 
is expected to move forward on setting Maximum 
Available Control Technology (MACT) standards for 
coal- and oil-fired electric generating units. Upon 
publication in the federal register following finalization, 
affected electric generating units (EGUs) will have 
three years to come into compliance with the new 
requirements. At this time, DP&L is unable to deter-
mine the impact of the promulgation of new MACT 
standards on its financial position or results of opera-
tions; however, a MACT standard could have a  
material adverse effect on our operations, in particular, 
our unscrubbed units. We cannot at this time project 
the final costs we may incur to comply with any  
resulting mercury restriction regulations.

On January 5, 2005, the USEPA published its final 

non-attainment designations for the National Ambient 
Air Quality Standard (NAAQS) for Fine Particulate 
Matter 2.5 (PM 2.5). These designations included 
counties and partial counties in which DP&L operates 
and/or owns generating facilities. On March 4, 2005, 
DP&L and other Ohio electric utilities and electric 
generators filed a petition for review in the D.C. Circuit 
Court of Appeals, challenging the final rule creat-
ing these designations. On November 30, 2005, the 
court ordered the USEPA to decide on all petitions for 
reconsideration by January 20, 2006. On January 20, 
2006, the USEPA denied the petitions for reconsidera-
tion. On July 7, 2009, the D.C. Circuit Court of Appeals 
upheld the USEPA non-attainment designations for the 
areas impacting DP&L’s generation plants, however, 
on October 8, 2009, the USEPA issued new designa-
tions based on 2008 monitoring data that showed all 
areas in attainment to the standard with the exception 
of several counties in northeastern Ohio. The USEPA is 
expected to propose revisions to the PM 2.5 standard 
in late 2010 as part of its routine five-year rule review 
cycle. At this time, DP&L is unable to determine the 
impact the revisions to the PM 2.5 standard will have 
on its financial position or results of operations.

On May 5, 2004, the USEPA issued its proposed 
regional haze rule, which addresses how states should 
determine the Best Available Retrofit Technology 
(BART) for sources covered under the regional haze 
rule. Final rules were published July 6, 2005, provid-
ing states with several options for determining whether 
sources in the state should be subject to BART. In the 
final rule, the USEPA made the determination that CAIR 
achieves greater progress than BART and may be 
used by states as a BART substitute. Numerous units 
owned and operated by us will be impacted by BART. 
We cannot determine the extent of the impact until 
Ohio determines how BART will be implemented. 

In response to a U.S. Supreme Court decision that 

the USEPA has the authority to regulate CO2 emis-
sions from motor vehicles, the USEPA made a finding 
that CO2 and certain other gases are pollutants under 
the CAA. The USEPA has not yet identified the specif-
ics of how these newly designated pollutants will be 
regulated. In April 2009, the USEPA issued a proposed 
endangerment finding under the CAA. The proposed 
finding determined that CO2 and other GHGs from 
motor vehicles threaten the health and welfare of 
future generations by contributing to climate change. 
If the proposed finding is finalized, it could lead to the 
regulation of CO2 and other GHGs from sources other 
than motor vehicles, including coal-fired plants that 
we own and operate. Recently, several bills have been 
introduced at the federal level to regulate GHG emis-
sions. In June 2009, the U.S. House of Representatives 

DPL Inc.  115

 
passed H.R. 2454, the American Clean Energy and 
Security Act (ACES). This proposed legislation tar-
gets a reduction in the emission of GHGs from large 
sources by 80% in 2050 through an economy wide cap 
and trade program. ACES also includes energy effi-
ciency and renewable energy initiatives. Approximately 
99% of the energy we produce is generated by coal. 
DP&L’s share of CO2 emissions at generating stations 
we own and co-own is approximately 16 million tons 
annually. Proposed GHG legislation finalized at a future 
date could have a significant effect on DP&L’s opera-
tions and costs, which could adversely affect our net 
income, cash flows and financial position. However, 
due to the uncertainty associated with such legislation, 
we are currently unable to predict the final outcome or 
the financial impact that this legislation will have on us. 
On September 22, 2009, the USEPA issued a final rule 
for mandatory reporting of GHGs from large sources 
that emit 25,000 metric tons per year or more of CO2, 
including electric generating units. The first report is 
due in March 2011 for 2010 emissions. This reporting 
rule will guide development of policies and programs 
to reduce emissions. DP&L does not anticipate that 
this reporting rule will result in any significant cost or 
other impact on current operations. 

On July 15, 2009, the USEPA proposed revisions 

to its primary National Ambient Air Quality Standard 
(NAAQS) for nitrogen dioxide. This change could affect 
certain emission sources in heavy traffic areas like the 
I-75 corridor between Cincinnati and Dayton. At this 
point, DP&L cannot determine the effect of this poten-
tial change, if any, on its operations.

The USEPA proposed revisions to its primary 
NAAQS for SO2 on November 16, 2009. This would 
replace the current 24-hour standard and current annu-
al standard. This regulation is expected to be finalized 
in 2010. At this time, DP&L cannot determine the effect 
of this potential change, if any, on its operations.

On September 16, 2009, the USEPA announced 
that it would reconsider the 2008 national ground level 
ozone standard. A more stringent ambient ozone stan-
dard may lead to stricter NOx emission standards in 
the future. At this point, DP&L cannot determine the 
effect of this potential change, if any, on its operations.

Air Quality – Litigation Involving Co-Owned Plants

In March 2000, as amended in June 2004, the U.S. 
Department of Justice filed a complaint in the United 
States District Court, Southern District of Indiana, 
Indianapolis Division against Cinergy Corp. (now part 
of Duke Energy) and two Cinergy subsidiaries for 
alleged violations of the CAA at various generation 
units operated by PSI Energy, Inc. and CG&E, includ-
ing generation units co-owned by DP&L (Beckjord Unit 

6 and Miami Fort Unit 7). A retrial has been held in 
which the second jury found for Duke Energy on some 
allegations, but for plaintiffs with respect to units at 
another one of Duke Energy’s wholly-owned facilities. In 
a separate phase II remedies trial with respect to viola-
tions found in the first trial, Duke Energy was ordered 
to close down three of its wholly-owned generating 
units by September 2009, surrender some emission 
allowances and pay a fine. None of the violations found 
or remedies ordered relate to generating units owned 
in part by DP&L. 

In 2004, eight states and the City of New York 
filed a lawsuit in Federal District Court for the Southern 
District of New York against American Electric Power  
Company, Inc. (AEP), one of AEP’s subsidiaries,  
Cinergy Corp. (a subsidiary of Duke Energy Corporation 
(Duke Energy)) and four other electric power compa-
nies. A similar lawsuit was filed against these compa-
nies in the same court by Open Space Institute, Inc., 
Open Space Conservancy, Inc. and The Audubon 
Society of New Hampshire. The lawsuits allege that 
the companies’ emissions of CO2 contribute to global 
warming and constitute a public or private nuisance. 
The lawsuits seek injunctive relief in the form of specific 
emission reduction commitments. In 2005, the Federal 
District Court dismissed the lawsuits, holding that the 
lawsuits raised political questions that should not be 
decided by the courts. The plaintiffs appealed. Finding 
that the plaintiffs have standing to sue and can assert 
federal common law nuisance claims, the United States 
Court of Appeals for the Second Circuit on September 
21, 2009 vacated the dismissal of the Federal District 
Court and remanded the lawsuits back to the Federal 
District Court for further proceedings. Although we are 
not named as a party to these lawsuits, DP&L is a co-
owner of coal-fired plants with Duke Energy and AEP 
(or their subsidiaries) that could be affected by the 
outcome of these lawsuits. The Second Circuit Court’s 
decision could also encourage these or other plain-
tiffs to file similar lawsuits against other electric power 
companies, including us. We are unable at this time 
to predict with certainty the impact that these lawsuits 
might have on us. 

On September 21, 2004, the Sierra Club filed a 
lawsuit against DP&L and the other owners of the J.M. 
Stuart generating station in the U.S. District Court for 
the Southern District of Ohio for alleged violations of 
the CAA and the station’s operating permit. On August 
7, 2008, a consent decree was filed in the U.S. District 
Court in full settlement of these CAA claims. Under 
the terms of the consent decree, DP&L and the other 
owners of the J.M. Stuart generating station agreed 
to: (i) certain emission targets related to NOx, SO2 
and particulate matter; (ii) make energy efficiency and 

116  DPL Inc.

renewable energy commitments that are conditioned 
on receiving PUCO approval for the recovery of costs; 
(iii) forfeit 5,500 SO2 allowances; and (iv) provide fund-
ing to a third party non-profit organization to establish a 
solar water heater rebate program. DP&L and the other 
owners of the station also entered into an attorneys’ fee 
agreement to pay a portion of the Sierra Club’s attor-
ney and expert witness fees. The parties to the lawsuit 
filed a joint motion on October 22, 2008, seeking an 
order by the U.S. District Court approving the consent 
decree with funding for the third party non-profit orga-
nization set at $300,000. On October 23, 2008, the 
U.S. District Court approved the consent decree. On 
October 21, 2009, the Sierra Club filed with the U.S. 
District Court a motion for enforcement of the consent 
decree based on the Sierra Club’s interpretation of the 
consent decree that would require certain NOx emis-
sions that DP&L has been excluding from its computa-
tions to be included for purposes of complying with 
the emission targets and reporting requirements of the 
consent decree. DP&L believes that it is properly com-
puting and reporting NOx emissions under the consent 
decree and has opposed the Sierra Club’s motion. A 
decision on the motion is expected before the end of 
the first quarter 2010. Because J.M. Stuart Station’s 
NOx emissions are well below the 2009 and 2010 limits 
in the consent decree under either method of calcula-
tion, an adverse decision would have no effect in 2010 
on operations or costs. An adverse decision could 
affect compliance costs in future years when the NOx 
limits are further reduced under the consent decree.

Air Quality – Notices of Violation Involving  
Co-Owned Plants

On March 13, 2008, Duke Energy Ohio Inc., the opera-
tor of the Zimmer generating station, received a NOV 
and a Finding of Violation from the USEPA alleging 
violations of the CAA, the Ohio State Implementation 
Program (SIP) and permits for the Station in areas 
including SO2, opacity and increased heat input. 
DP&L is a co-owner of the Zimmer generating station 
and could be affected by the eventual resolution of this 
matter. Duke Energy Ohio Inc. is expected to act on 
behalf of itself and the co-owners with respect to this 
matter. At this time, DP&L is unable to predict the out-
come of this matter. 

In June 2000, the USEPA issued a NOV to the 
DP&L-operated J.M. Stuart generating station (co-
owned by DP&L, CG&E, and CSP) for alleged viola-
tions of the CAA. The NOV contained allegations 
consistent with NOVs and complaints that the USEPA 
had recently brought against numerous other coal-fired 
utilities in the Midwest. The NOV indicated the USEPA 
may: (1) issue an order requiring compliance with the 

requirements of the Ohio SIP; or (2) bring a civil action 
seeking injunctive relief and civil penalties of up to 
$27,500 per day for each violation. To date, neither 
action has been taken. At this time, DP&L cannot pre-
dict the outcome of this matter. 

In November 1999, the USEPA filed civil com-

plaints and NOVs against operators and owners of 
certain generation facilities for alleged violations of the 
CAA. Generation units operated by CG&E (Beckjord 
Unit 6) and CSP (Conesville Unit 4) and co-owned by 
DP&L were referenced in these actions. Numerous 
northeast states have filed complaints or have indicat-
ed that they will be joining the USEPA’s action against 
CG&E and CSP. Although DP&L was not identified in 
the NOVs, civil complaints or state actions, the results 
of such proceedings could materially affect DP&L’s 
co-owned plants. 

In December 2007, the Ohio EPA issued a NOV 
to the DP&L-operated Killen generating station (co-
owned by DP&L and CG&E) for alleged violations of 
the CAA. The NOVs alleged deficiencies in the continu-
ous monitoring of opacity. We submitted a compliance 
plan to the Ohio EPA on December 19, 2007. To date, 
no further actions have been taken by the Ohio EPA. 

Air Quality – Other Issues Involving Co-Owned Plants

In 2006, DP&L detected a malfunction with its emission 
monitoring system at the DP&L-operated Killen gen-
erating station (co-owned by DP&L and CG&E) and 
ultimately determined its SO2 and NOx emissions data 
were under reported. DP&L has petitioned the USEPA 
to accept an alternative methodology for calculating 
actual emissions for 2005 and the first quarter 2006. 
DP&L has sufficient allowances in its general account 
to cover the understatement and is working with the 
USEPA to resolve the matter. Management does not 
believe the ultimate resolution of this matter will have  
a material impact on results of operations, financial 
position or cash flows. 

Air Quality – Notices of Violation Involving  
Wholly-Owned Plants

In 2007, the Ohio EPA and the USEPA issued NOVs 
to DP&L for alleged violations of the CAA at the O.H. 
Hutchings Station. The NOVs alleged deficiencies 
relate to stack opacity and particulate emissions. 
Discussions are under way with the USEPA, the U.S. 
Department of Justice and Ohio EPA. DP&L has pro-
vided data to those agencies regarding its mainte-
nance expenses and operating results. On December 
15, 2008, DP&L received a request from the USEPA for 
additional documentation with respect to those issues 
and other CAA issues including issues relating to capi-
tal expenses and any changes in capacity or output  

DPL Inc.  117

 
of the units at the O.H. Hutchings station. During 2009, 
DP&L has continued to submit various other operation-
al and performance data to the USEPA in compliance 
with its request. DP&L is currently unable to determine 
the timing, costs or method by which the issues may 
be resolved and continues to work with the USEPA  
on this issue. 

On November 18, 2009, the USEPA issued a  
NOV to DP&L for alleged New Source Review (NSR) 
violations of the CAA at the O.H. Hutchings Station 
relating to capital projects performed in 2001 involving 
Unit 3 and Unit 6. DP&L does not believe that the 
two projects described in the NOV were modifications 
subject to NSR. DP&L is unable to determine the 
timing, costs or method by which these issues may  
be resolved and continues to work with the USEPA  
on this issue.

Water Quality 
On July 9, 2004, the USEPA issued final rules pursuant 
to the Clean Water Act governing existing facilities that 
have cooling water intake structures. The rules require 
an assessment of impingement and/or entrainment of 
organisms as a result of cooling water withdrawal.  
A number of parties appealed the rules to the Federal 
Court of Appeals for the Second Circuit in New York 
and the Court issued an opinion on January 25, 2007 
remanding several aspects of the rule to the USEPA 
for reconsideration. Several parties petitioned the U.S. 
Supreme Court for review of the lower court decision. 
On April 14, 2008, the Supreme Court elected to review 
the lower court decision on the issue of whether the 
USEPA can compare costs with benefits in determining 
the best technology available for minimizing adverse 
environmental impact at cooling water intake struc-
tures. Briefs were submitted to the Court in the summer 
of 2008 and oral arguments were held in December 
2008. In April 2009, the U.S. Supreme Court ruled that 
the USEPA did have the authority to compare costs 
with benefits in determining best technology available. 
The USEPA is developing proposed regulations which 
it hopes to issue for public comment by mid-2010. 

On May 4, 2004, the Ohio EPA issued a final 
National Pollutant Discharge Elimination System permit 
(the Permit) for J.M. Stuart Station that continued our 
authority to discharge water from the station into the 
Ohio River. During the three-year term of the Permit, 
we conducted a thermal discharge study to evaluate 
the technical feasibility and economic reasonableness 
of water cooling methods other than cooling towers. 
In December 2006, we submitted an application for 
the renewal of the Permit that was due to expire on 
June 30, 2007. In July 2007 we received a draft permit 
proposing to continue our authority to discharge water 

from the station into the Ohio River. On February 5, 
2008 we received a letter from Ohio EPA indicating that 
they intended to impose a compliance schedule as 
part of the final Permit, that requires us to implement 
one of two diffuser options for the discharge of water 
from the station into the Ohio River as identified in the 
thermal discharge study. Subsequently, representatives 
from DP&L and the Ohio EPA have agreed to allow 
DP&L to restrict public access to the water discharge 
area as an alternative to installing one of the diffuser 
options. Ohio EPA issued a revised draft permit that 
was received on November 12, 2008. In December 
2008, the USEPA requested that the Ohio EPA provide 
additional information regarding the thermal discharge 
in the draft permit. In June 2009, DP&L provided 
information to the USEPA in response to their request  
to Ohio EPA. The timing for issuance of a final permit  
is uncertain.

In September 2009, the USEPA announced that it 
will be revising technology-based regulations govern-
ing water discharges from steam electric generating 
facilities such as J.M. Stuart, Killen and O.H. Hutchings 
Stations. The rulemaking will include the collection of 
information via an industry-wide questionnaire as well 
as targeted water sampling efforts at selected facili-
ties. Subsequent to the information collection effort, it 
is anticipated that the USEPA will release a proposed 
rule in 2011 with final regulations issued in late 2012 or 
early 2013. At present, DP&L is unable to predict the 
impact this rulemaking will have on its operations.

Land Use and Solid Waste Disposal
In September 2002, DP&L and other parties received 
a special notice that the USEPA considers us to be a 
PRP for the clean-up of hazardous substances at the 
South Dayton Dump landfill site. In August 2005, DP&L 
and other parties received a general notice regard-
ing the performance of a Remedial Investigation and 
Feasibility Study (RI/FS) under a Superfund Alternative 
Approach. In October 2005, DP&L received a special 
notice letter inviting it to enter into negotiations with 
the USEPA to conduct the RI/FS. No recent activity 
has occurred with respect to that notice or PRP status. 
More recently, DP&L has received requests by the 
USEPA and the existing PRP group to allow access to 
be given to DP&L’s service center building site, which 
is across the street from the landfill site. The USEPA 
requested access to drill monitoring and test wells to 
determine the extent of the landfill site’s contamination 
as well as to assess whether certain chemicals used 
at the service center building site might have migrated 
through groundwater to the landfill site. Pursuant to an 
Administrative Order issued by the USEPA requiring 
access to DP&L’s service center building site, DP&L 

118  DPL Inc.

has granted such access and drilling of soil borings 
and installation of monitoring wells occurred in the fall 
of 2009. DP&L believes the chemicals used at its ser-
vice center building site were appropriately disposed 
of and have not contributed to the contamination at the 
South Dayton Dump landfill site. While DP&L is unable 
at this time to predict the outcome of this matter, if 
DP&L were required to contribute to the clean-up of 
the site, it could have a material adverse effect on us. 
DP&L is also unable at this time to predict whether the 
monitoring and test wells may lead to any actions relat-
ing to the service center building site independent of 
the South Dayton Dump clean-up.

In December 2003, DP&L and other parties 
received a special notice that the USEPA considers us 
to be a PRP for the clean-up of hazardous substances 
at the Tremont City landfill site. Information available to 
DP&L does not demonstrate that it contributed hazard-
ous substances to the site. While DP&L is unable at 
this time to predict the outcome of this matter, if DP&L 
were required to contribute to the clean-up of the site, 
it could have a material adverse effect on us.

In November 2007, a PRP group contacted DP&L 
seeking our financial participation in a settlement that 
the group had reached with the federal government 
with respect to the clean-up of an industrial site once 
owned by Carolina Transformer, Inc. DP&L’s business 
records clearly show we did not conduct business with 
Carolina Transformer that would require our participa-
tion in any clean-up of the site. DP&L has declined 
to participate in the clean-up of this site. While DP&L 
is unable at this time to predict the outcome of this 
matter, if DP&L were required to contribute to the 
clean-up of the site, it could have a material adverse 
effect on us.

During 2008, a major spill occurred at an ash pond 

owned by the Tennessee Valley Authority (TVA) as a 
result of a dike failure. The spill generated a significant 
amount of national news coverage, and support for 
tighter regulations for the storage and handling of coal 
combustion products. DP&L has ash ponds at the 
Killen, O.H. Hutchings and J.M. Stuart stations which 
it operates, and also at generating stations operated 
by others but in which DP&L has an ownership inter-
est. We frequently inspect our ash ponds and do not 
anticipate any similar failures. It is widely expected 
that the federal government will propose new regula-
tions covering ash generated from the combustion of 
coal and including additional monitoring, testing, or 
construction standards with respect to ash ponds and 
ash landfills. During March 2009, the USEPA, through 
a formal Information Collection Request, collected 
information on ash pond facilities across the coun-
try, including those at Killen and J.M. Stuart stations. 

Subsequently the USEPA collected similar information 
for O.H. Hutchings Station. In addition, during August 
and October 2009, representatives of the USEPA vis-
ited J.M. Stuart Station to collect information on plant 
operations relative to the production and handling of 
by-products. Due to the wide range of possible out-
comes, DP&L is unable at this time to predict the tim-
ing or the financial impact of any future governmental 
initiative that may occur.

In addition, as a result of the TVA ash pond spill, 
there has been increasing advocacy to regulate coal 
combustion byproducts as hazardous waste under the 
Resource Conservation Recovery Act, Subtitle C. On 
October 15, 2009, the USEPA provided a draft rule to 
the Office of Management and Budget for interagency 
review. The draft rule proposed to regulate coal ash as 
a hazardous waste, with limited beneficial reuse. DP&L 
is unable at this time to predict the financial impact of 
this regulation, but if coal combustion byproducts are 
regulated as hazardous waste, it is expected to have a 
material adverse impact on operations.

Legal and Other Matters

In February 2007, DP&L filed a lawsuit against a coal 
supplier seeking damages incurred due to the sup-
plier’s failure to supply approximately 1.5 million tons 
of coal to two jointly owned plants under a coal supply 
agreement, of which approximately 570 thousand tons 
was DP&L’s share. DP&L obtained replacement coal 
to meet its needs. The supplier has denied liability, and 
is currently in federal bankruptcy proceedings. DP&L 
is unable to determine the ultimate resolution of this 
matter at this time. DP&L has not recorded any assets 
relating to possible recovery of costs in this lawsuit.

On May 16, 2007, DPL filed a claim with Energy 

Insurance Mutual (EIM) to recoup legal expenses 
associated with our litigation against certain former 
executives. Arbitration on that claim occurred on May 
13, 2009. The arbitration panel issued a ruling in Phase 
1 of the arbitration on September 25, 2009, finding that 
most of the claims involving the former executives were 
covered. The matter is pending.

As a member of PJM, DP&L is also subject to 
charges and costs associated with PJM operations as 
approved by the FERC. FERC Orders issued in 2007 
regarding the allocation of costs of large transmission 
facilities within PJM, could result in additional costs 
being allocated to DP&L of approximately $12 mil-
lion or more annually by 2012. DP&L filed a notice of 
appeal to the U.S. Court of Appeals, D.C. Circuit on 
March 18, 2008 challenging the allocation method. 
The appeal was consolidated with other appeals taken 
by other interested parties of the same FERC Orders 
and the consolidated cases were assigned to the 7th 

DPL Inc.  119

 
Circuit. On August 6, 2009, the 7th Circuit ruled that the FERC had failed to provide a reasoned basis for the allo-
cation method it had approved. Rehearings were filed by other interested litigants and denied by the Court, which 
then remanded the matter to the FERC for further proceedings. On January 21, 2010, the FERC issued a procedur-
al order on remand establishing a paper hearing process under which PJM will make an informational filing in late 
February. Subsequently PJM and other parties, including DP&L, will be able to file initial comments, testimony, and 
recommendations and reply comments. Absent future changes to the procedural schedule that may occur for a 
number of reasons including if settlement discussions are held, the paper hearing process should be complete and 
the case ready for FERC consideration in 2010. FERC did not establish a deadline for its issuance of a substantive 
order. DP&L cannot predict the timing or the likely outcome of the proceeding. Until such time as FERC may act to 
approve a change in methodology, PJM will continue to apply the allocation methodology that had been approved 
by FERC in 2007. Although we continue to maintain that these costs should be borne by the beneficiaries of these 
projects and that DP&L is not one of these beneficiaries, any new credits or additional costs resulting from the ulti-
mate outcome of this proceeding will be reflected in DP&L’s TCRR rider which is already in place to pass through 
RTO-related costs and credits.

In June 2009, the NERC, a FERC-certified electric reliability organization responsible for developing and 
enforcing mandatory reliability standards, commenced a routine audit of DP&L’s operations. The audit, which was 
for the period June 18, 2007 to June 25, 2009, evaluated DP&L’s compliance with 42 requirements in 18 NERC-
reliability standards. DP&L is currently subject to a compliance audit at a minimum of once every three years as 
provided by the NERC Rules of Procedure. This audit was concluded in June 2009 and its findings revealed that 
DP&L had some Possible Alleged Violations (PAVs) associated with five NERC Reliability Standards. In response 
to the report, DP&L filed mitigation plans with NERC to address the PAVs. These mitigation plans have been 
accepted and DP&L is currently awaiting a proposal for settlement from NERC. While we are currently unable to 
determine the extent of penalties, if any, that may be imposed on DP&L, we do not believe such penalties will have 
a material impact on our results of operations.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of
DPL Inc.:

We have audited the accompanying Consolidated Balance Sheets of DPL Inc. and subsidiaries (the Company)  
as of December 31, 2009 and 2008, and the related Consolidated Statements of Results of Operations, Shareholders’ 
Equity and Cash Flows for each of the years in the three-year period ended December 31, 2009. In connection with 
our audits of the consolidated financial statements, we have audited the consolidated financial statement schedule, 
“Schedule II – Valuation and Qualifying Accounts.” We also have audited the Company’s internal control over  
financial reporting as of December 31, 2009, based on criteria established in Internal Control – Integrated Framework 
issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s  
management is responsible for these consolidated financial statements, 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 these consolidated financial statements and an opinion on the Company’s internal control over 
financial reporting 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 audits to obtain reasonable assurance  
about whether the financial statements are free of material misstatement and whether effective internal control over 
financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included 
examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing 
the accounting principles used and significant estimates made by management, and evaluating the overall financial 
statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of 
internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating 
the design and operating effectiveness of internal control based on the assessed risk. Our audits also included  
performing such other procedures as we considered necessary in the circumstances. We believe that our audits  
provide a reasonable basis for our opinions.

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 misstate-

ments. 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 consolidated financial statements referred to above present fairly, in all material respects,  
the financial position of the Company as of December 31, 2009 and 2008, and the results of its operations and its 
cash flows for each of the years in the three-year period ended December 31, 2009, in conformity with U.S.  
generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects,  
effective internal control over financial reporting as of December 31, 2009, based on criteria established in Internal 
Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

The Board of Directors and Shareholder of
The Dayton Power and Light Company:

We have audited the accompanying Balance Sheets of The Dayton Power and Light Company (DP&L) as of December

Item 9A Controls and Procedures

Disclosure Controls and Procedures

Our Chief Executive Officer (CEO) and Chief Financial Officer (CFO) are responsible for establishing and  
maintaining our disclosure controls and procedures. These controls and procedures were designed to ensure  
that material information relating to us and our subsidiaries are communicated to the CEO and CFO. We  
evaluated these disclosure controls and procedures as of the end of the period covered by this report with the  
participation of our CEO and CFO. Based on this evaluation, our CEO and CFO concluded that our disclosure  
controls and procedures are effective: (i) to ensure that information required to be disclosed by us in the reports 
that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the  
time periods specified in the SEC’s rules and forms; and (ii) to ensure that information required to be disclosed  
by us in the reports that we submit under the Exchange Act is accumulated and communicated to our  
management, including our principal executive and principal financial officers, or persons performing similar  
functions, as appropriate, to allow timely decisions regarding required disclosure.

There was no change in our internal control over financial reporting during the most recently completed  

fiscal period that has materially affected, or is reasonably likely to materially affect, internal control over  
financial reporting.

The following report is our report on internal control over financial reporting as of December 31, 2009.

Management’s Report on Internal Control over Financial Reporting 

We are responsible for establishing and maintaining adequate internal control over financial reporting, as  
such term is defined in Exchange Act Rule 13a-15(f). Under the supervision and with the participation of manage-
ment, including the CEO and CFO, we conducted an evaluation of the effectiveness of our internal control over 
financial reporting based on the framework in Internal Control – Integrated Framework issued by the Committee 
of Sponsoring Organizations of the Treadway Commission. Based on an evaluation under the framework in  
Internal Control – Integrated Framework, we concluded that our internal control over financial reporting was effec-
tive as of December 31, 2009. 

Our internal control over financial reporting as of December 31, 2009, has been audited by KPMG LLP,  
the independent registered public accounting firm that audited the financial statements contained herein, as  
stated in their report which is included herein.

Stock Purchase and Dividend Reinvestment Plan
On March 1, 2009, DPL introduced a new direct stock pur-
chase and dividend reinvestment plan. The new plan is offered 
and administered by Computershare Trust Company, N.A., 
(Computershare) and not by DPL. This Computershare Invest-
ment Plan (CIP) provides an alternative to traditional retail 
brokerage methods of purchasing, holding and selling DPL 
shares. Both registered shareholders and new investors are 
able to purchase shares through this program.

The CIP offers a full array of features that include the ability to:
o  Purchase shares weekly 
o  Purchase initial shares through the CIP, as a new investor, 
for $250.00 in one payment or ten consecutive monthly  
payments of $25.00 
o  Purchase additional shares by investing as little as $25.00 
o  Authorize recurring monthly purchases through the 
automatic investment feature 
o  Purchase shares over the Internet at 
www.computershare.com/investor or by check 
o  Reinvest dividends or receive cash dividends electronically 
or by check 
o  Convert your stock certificates into book-entry shares for 
safekeeping purposes at no cost 
o  Transfer shares to another person by opening a CIP 
account for the recipient 
o  Sell shares daily 

To participate in the CIP, you can enroll over the Internet  
at https://www.computershare.com/investor or call  
Computershare for the brochure and form at 800-736-3001  
or call DPL Shareholder Services at 800-322-9244.

Dividend Direct Deposit
Shareholders who are not reinvesting their dividends in  
DPL may choose to have their dividend payments deposited 
directly into a savings or checking account. This free service 
ensures that payments will be available on the payment  
date, eliminating potential for mail delays and lost checks.  
To enroll, contact Computershare at 800-736-3001, visit  
www.computershare.com/investor, or call DPL Shareholder 
Services at 800-322-9244.
