Chairman’s Letter 

Dear Fellow Stakeholders:

Thanks to the commitment and dedication of our 1,500 
employees, the executive team and my fellow directors, 
I am proud to report that the strategic moves initiated 
since 2004 are paying off. Today, DPL Inc. is a 
healthy, focused, integrated electric company, striving 
for excellence in every facet of our business.

Once again, we had a good year as earnings per 

share from continuing operations increased from 
$1.03 in 2006 to $1.80. Our fi nancial position allowed 
us to announce dividend increases on two separate 
occasions during 2007 for a total increase of 10%.

We met our commitment to achieve an investment 

grade credit profi le. With Standard and Poor’s 
upgrade in early 2007, all three rating agencies have 
at least an investment grade rating on DPL. This is a 
positive refl ection of the actions we have taken to 
strengthen our balance sheet and corporate governance 
while reducing our risk profi le.

The future is equally exciting. As new energy 
legislation and regulations work their way through Ohio 
state government, DPL will continue to adapt while 
keeping an eye on the basics of running a quality 
electric business, focusing on operational excellence 
and investing in quality customer service.

For strategic oversight, my fellow directors provide 

Board of Directors

an excellent balance of business and fi nancial expertise, 
industry experience and community knowledge.

On this front, I would like to express our sincere 

gratitude to Ernie Green who chose to retire as a 
director after 16 years of outstanding service. 
Ernie’s integrity and business expertise were of great 
value to the company and set a standard of excellence 
for all of us to emulate. Thank you, Ernie.

At the same time, we welcome Frank Gallaher to 
the board. Frank brings more than 30 years of experience 
in positions of leadership in the electric business. 
His operational knowledge will be a tremendous asset.
Likewise, we continue to invest in the outstanding 

group of employees we have at DPL. In a joint union-
management effort, we are reinforcing the positive 
values that make DPL a great company, proudly serving 
515,000 customers. And at the executive level, we 
are strengthening our leadership team and broadening 
our bench strength.

Our company’s future is bright, our viewpoint is 

optimistic, and our mindset is opportunistic. 
Thank you for allowing the board of directors the honor 
of serving you.

And, thank you for your investment in DPL.

President & CEO’s Letter

To My Fellow DPL Stakeholders:

We are DPL –  
It’s not just a slogan that we created for the annual 
report. It’s the opening line of our values statement – 
a statement that was developed by a joint 
union-management team representing all areas 
of the company.

The team created a set of core values that refl ect 

the tremendous pride that employees have in DPL 
and set expectations for the manner in which we treat 
our employees, customers, investors and all other 
DPL stakeholders.

In the end, it is our people, and our values, 

that are at the heart of our success.

Now, I’d like to share with you what our 

outstanding workforce accomplished in 2007, and 
how they are leading DPL into the future.

Solid Financial Performance

First, we are pleased with the year’s fi nancial perfor-
mance. Earnings per share from continuing operations 
were up $0.77 to $1.80. These positive results were 
driven by increased revenue as we recover rising fuel 
and environmental costs. In addition, interest expense 
was down due to debt retirement, and depreciation 
costs were lower refl ecting, in part, the sale of two 
peaking plants in 2006.

Our healthy fi nancial position and positive outlook 
enabled the board to announce dividend increases on 
two separate occasions in 2007 – for a total increase 
of 10%. We understand the importance of the dividend 
to our investors and will continue to review it on a 
regular basis.

Cost-Competitive Generation

Turning to our generation assets, a renewed point 
of emphasis for 2007 and going forward is operational 
excellence. Simply put, that means safely and cost 
effectively running the plants at a high level of effi ciency 
and availability.

To this end, we made a number of moves during 

the year to strengthen the management of these 
valuable assets. Our power production group has new 
leadership, we have added individuals with extensive 
production experience, and we have reorganized 
to better utilize our resources and share best practices 
across plants.

At the same time, we are nearing completion of 

the largest environmental capital project ever 
undertaken by DPL – a $580 million investment in fl ue 
gas desulfurization (FGD) equipment. FGDs, commonly 

2

Paul M. Barbas

called scrubbers, remove almost all sulfur dioxide 
from emissions and help DPL comply with environmental 
regulations.

The DPL team has successfully brought scrubbers 
on line for the one unit at Killen Station and the fi rst unit 
at Stuart Station. By mid-year 2009, approximately 80% 
of our coal-fi red generation will be scrubbed.

DPL’s environmental investment is unique in the 
industry in that we were the fi rst major utility in North 
America to utilize a new technology, developed by 
the Chiyoda Corporation of Japan. Upon completion, 
DPL’s scrubbers will have been installed at a cost per 
megawatt that is well below the industry average. 
This innovative solution will help keep our generation 
competitive while controlling costs for customers.

Reliable Customer Service

In terms of customer service, our goal is continuous 
improvement. We constantly measure performance 
and evaluate ways to meet and exceed our customers’ 
expectations.

In 2006, we initiated a customer satisfaction survey 

as a new performance metric. Based on these results, 
we targeted communications with our customers 
as an area of focus in 2007. Call center representatives 
and fi eld employees attended training to help further 
develop customer relations skills. The training also 
allowed employees a forum to provide valuable input 

and feedback on how best to serve customers.

The year-end 2007 survey results showed positive 

gains. We earned higher marks in areas such as 
professionalism, responsiveness and overall customer 
service performance.

In addition to investing in our employees, we 

continue to invest in the reliability of our distribution 
system, allowing us to meet the demands of a record 
peak load in 2007. Signifi cant capital projects were 
completed to accommodate industrial growth in parts 
of our West Central Ohio service area. We also 
completed a collaborative project to improve reliability 
in an area near the Indiana border by teaming up 
with a neighboring utility.

Leadership and Bench Strength

Another accomplishment of note is the investment we 
are making in our people. During the year, we hired 
more than 140 new employees. Many of these were at 
our power plants and will be involved in the operation of 
the scrubbers. However, a number of employees have 
been hired into areas throughout the company.

At the executive level, we have also made signifi -
cant moves. Ten of thirteen members of the executive 
team are either new to the company or are in different 
roles than in 2006. This includes the new position 
of senior vice president of human resources, which we 
added to increase our emphasis on the growth and 
development of our employees.

The infusion of new talent is providing a good bal-
ance of experienced company personnel and employ-
ees with different backgrounds and perspectives. 

Our Unifying Values

Most importantly, it is allowing us to improve our bench 
strength, develop existing and future leaders, and 
employ the human capital needed to grow this company.

Future Optimism

Going forward, we have a positive outlook for the 
future. As the state of Ohio debates its regulatory 
framework, DPL is uniquely positioned among Ohio 
electric utilities by having a rate plan in place through 
2010. The plan provides stable prices for customers 
while allowing the company to partially recover 
costs and grow revenues.

At the same time, our capital investment program 

for environmental equipment is in its fi nal stages. 
As a result, we are projecting positive free cash fl ow in 
2008 and 2009. Likewise, earnings per share from 
continuing operations are projected to steadily grow 
through 2009.

We realize the energy landscape will continue to 

change and there are challenges ahead, but those 
challenges also create opportunities. While our near 
term focus is execution, rest assured that we are 
keeping our eye on the longer term opportunities.

Thank you for your continued support.

We care about DPL 
being a great company!

DPL employees come from all 
walks of life, with a variety of technical 
and professional backgrounds. Some 
have been with us for more than 50 
years. Others are just beginning their 
careers. In the end, our team consists of 
a diverse group of people that truly 
care about DPL being a great company!

It Starts with the Customer
Success in the utility business takes individuals 
that enjoy serving people. We work 24/7, 365 days 
a year. Sometimes, it requires personal sacrifi ce – 
missing a holiday with family or traveling across the 
country to help others in need. Our employees 
answer the call and take great pride in their ability 
to keep the lights on.

Reliability is the cornerstone of customer satisfaction. 
In 2007, like previous years, we met or exceeded 
reliability standards set by the Public Utilities 
Commission of Ohio.

To consistently achieve these results, we constantly 
analyze load data and system growth. This was

particularly important in 2007 as our system was 
pushed to new limits, setting a record peak demand 
on August 8.

Part of this load growth is being driven by pockets 
of industrial expansion within our service area. 
In Greenville and Washington Court House, DPL 
invested in its network to meet the needs of two new 
ethanol plants. While in Sidney, increased demand 
is due to the expansion of the area’s healthy 
manufacturing base, thanks, in part, to the strong 
automotive presence.

To better serve customers near our Indiana border, 
DPL worked with local government offi cials in 
Preble County and formed a unique partnership with 
Richmond Power and Light (RP&L) to strengthen 
reliability. When major accidents or storms disrupt 

power to the area, DPL can temporarily direct 
power from RP&L lines to DPL customers. 
This collaborative solution allows the power to 
keep fl owing while repairs are being made.

Beyond investments in reliability, we also ask 
customers to grade our performance. In 2006, we 
conducted a benchmark customer satisfaction survey 
to prioritize service efforts. Based on this feedback, 
additional customer relations training was 
provided for our telephone representatives and 
fi eld employees. Those who participated in the 
training also offered excellent input on how best to 
serve customers. The year-end 2007 survey 
showed positive gains in a number of targeted areas, 
including professionalism, responsiveness and 
overall customer service.

DPL employees are proud to serve customers – 
no matter where they are. With major ice storms in 
Michigan and Missouri during 2007, DPL crews 
endured treacherous conditions to help restore 
power to customers in those states. One Missouri 
resident thanked our employees by writing, 
“We are so blessed that you and others gave so 
unselfi shly of yourselves to come to our aid 
when our power went out.”

Serving Our Community
At DPL, service is more than the work we do inside 
offi ces, on power lines, or at the plants. It is 
visible in the way we care for our neighbors beyond 
the normal course of business.

DPL has an ongoing commitment to the communities 
it serves. Each year, the company and The DP&L 

Foundation donate more than $1 million to 
support local initiatives. While many causes have an 
educational focus, DPL also places economic 
development as a high priority. Most recently, the 
DP&L Foundation made a signifi cant contribution to 
support the Dayton Development Coalition’s 
Wright-Patt 2020 initiative to help achieve a goal of 
adding 10,000 jobs to the region by 2020.

Our employees are equally dedicated. To help their 
generous contributions go farther, the company 
initiated a charitable matching program in 2007. On 
an annual basis, DPL will match personal charitable 
contributions to qualifi ed nonprofi t organizations, 
up to $2,000 per employee.

In addition, employees actively participate in the 
company’s annual United Way and Culture Works 
campaigns, and help their neighbors through

food and blood drives. Thanks to these and many 
other efforts, DPL and Local 175 were recognized by 
the United Way with the Pinnacle Award and by 
the Ohio Arts Council with the Governor’s Award 
for the Arts. 

Competitive Generation
DPL’s 2,850 megawatts of cost-competitive, 
coal-fi red generation and 900 megawatts of peakers 
supply the power for our more than 515,000 customers. 
Produced at 10 different plants, approximately 65% of 
this capacity is owned in combination with other 
energy companies, allowing us to diversify operational 
risk. This way, we are not overly dependent on any 
single plant.

As a predominantly coal-fi red producer, DPL is 
committed to operating in an environmentally respon-
sible and compliant manner. Earlier in the decade, 
DPL invested $175 million in selective catalytic 
reduction (SCR) equipment to reduce nitrogen oxide 
(NOx) emissions. Since the SCRs were put into 
service in 2004, NOx emissions have been reduced 
by almost 40%.

Now, we are in the fi nal stages of our largest 
environmental capital investment program ever. DPL 
is investing $580 million to install fl ue gas desulfuriza-
tion (FGD) equipment, commonly called scrubbers, 
on 1,700 megawatts of coal-fi red generation. The 
scrubbers will reduce sulfur dioxide emissions, 
produce cleaner air, and help the company comply 
with environmental regulations. In addition, the

scrubbers, in conjunction with existing electrostatic 
precipitators, will capture signifi cant mercury and fi ne   
particulate emissions.

DPL was the fi rst major utility in North America to 
install the innovative Chiyoda scrubber technology
on its base load generating plants. Instead of using 
a traditional limestone spray tower, DPL’s units pump 
fl ue gas through a jet bubbling reactor containing a 
bath of limestone. Our early adoption of this scrubber 
technology will result in installed costs that are 
well below the industry average. Plus, the simplicity 
of the new design will help control operational and 
maintenance expenses, resulting in a cost-effective 
solution for our customers.

Our employees have done an outstanding job 
managing the scrubber construction program at the 
DPL-operated Killen and Stuart generating plants. 

In June of 2007, we reached a signifi cant milestone 
by bringing on line the scrubber at Killen. Since then, 
the scrubber on the fi rst unit at Stuart was completed 
in early 2008, with the remaining three scrubbers 
scheduled to come on line at Stuart later in the year.

DPL Commitment
A commitment to being a great company comes 
down to caring for all stakeholders – customers, 
employees, communities, and investors. 
As we move forward, we will be guided by our values: 
We will strive for excellence in every facet of our 
business. We are committed to long-term success.

We are DPL!

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 515,000 retail customers. DP&L also pur-
chases retail peak load requirements from DPL Energy, 
LLC (DPLE), one of DPL’s wholly-owned subsidiar-
ies. 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. 

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

DP&L has one significant subsidiary, DPL Finance 

Company, Inc., which is wholly-owned and provides 
financing to DPL, DP&L, and other affiliated companies. 
DPL and DP&L conduct their principal business in 

one business segment – Electric. 

Under the recently enacted Public Utility Holding 
Company Act of 2005, the Federal Energy Regulatory 
Commission (FERC) requires that utility holding compa-
nies comply with certain accounting, record retention 
and filing requirements. DPL believes it is exempt from 
these requirements because DP&L’s operations are 
confined to a single state. On January 31, 2006, DPL 
filed a FERC 65B Waiver Notification, with the FERC, 
requesting that the FERC approve DPL’s waiver and 
avoid FERC regulation.

DPL, DP&L, and its subsidiaries employed 1,562 
persons as of January 31, 2008, of which 1,333 were 
full-time employees and 229 were part-time employ-
ees. Approximately 54% of our employees are under 
a collective bargaining agreement. During the third 
quarter of 2008, we will begin negotiation discussions 
with employees covered under our collective bargain-
ing agreement which is set to expire in November 
2008. If the collective bargaining agreement expires 
before a new agreement is reached, we would attempt 
to persuade our employees to continue working while 
negotiations continue. We believe that we maintain a 
satisfactory relationship with our employees; however, it 

DPL Inc.

is possible that the expiration of the collective bargaining agreement could result in labor disruptions 
affecting some or all of our operations.

Long-Term Debt Redemption

On March 1, 2007, pursuant to the Company’s strategy 
of reducing its long-term debt, DPL redeemed the $225 
million 8.25% Senior Notes when they became due.

Insurance Recovery Claim

On April 18, 2007, DPL and Associated Electric & Gas 
Insurance Services (AEGIS) mediated and reached 
a settlement regarding an insurance claim filed with 
AEGIS on January 13, 2006 to recoup legal fees asso-
ciated with the three former executives in which AEGIS 
agreed to pay DPL $14.5 million for legal fees incurred 
by DPL and associated with this litigation. The settle-
ment agreement was signed and executed on April 
30, 2007 and the recovery was recorded by DPL as a 
reduction to operation and maintenance expense. 

Peaking Unit Sales

On April 25, 2007, DPLE completed the sale of its 
Darby and Greenville electric peaking generation facili-
ties, providing DPL with approximately $151 million 
in cash. Darby Station was sold to Columbus Southern 
Power (CSP), a utility subsidiary of American Electric 
Power (AEP), for approximately $102 million in cash. 
Greenville Station was sold to Buckeye Power, Inc. for 
approximately $49 million in cash. 

Executive Litigation Settlement

On May 21, 2007, we settled the litigation with the three 
former executives in exchange for our payment of $25 
million. The $25 million settlement was funded from 
the sale of financial assets held in DP&L’s Master Trust 
for deferred compensation. As a result of this settle-
ment, DPL realized a net pretax gain in continuing and 
discontinued operations of $31 million and $8.2 million, 
respectively. As part of this settlement, the three former 
executives relinquished and dismissed all their claims 
including those related to certain deferred compensa-
tion, restricted stock units (RSUs), MVE, Inc. (discon-

tinued subsidiary of DPL) incentives, stock options 
and legal fees. See Note 15 of Notes to Consolidated 
Financial Statements.

FGD Project Implementation

Installation of flue gas desulfurization (FGD) equip-
ment at the Killen Station was successfully completed 
in June 2007. DP&L is in the process of installing 
the same FGD technology on the four units at Stuart 
Station. The first Stuart Station unit was placed into 
service in early February 2008 with the remaining units 
to be commissioned prior to June 2008. 

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 Inc. 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 common stock with a fair value of $27.4 million to 
the Pension and resulting in a fully funded status at 
December 31, 2007.

Pollution Control Bonds

On November 15, 2007, the Ohio Air Quality 
Development Authority (OAQDA) issued $90 million of 
OAQDA Revenue Bonds 2007 Series A, due November 
2040. See Note 7 of Notes to Consolidated Financial 
Statements.

Increase in Dividends on DPL’s Common Stock 

On February 1, 2007 and on December 13, 2007, our 
Board of Directors authorized dividend increases of 
approximately 4% and 6%, respectively, increasing our 
dividend per share from $1.00 per share to $1.10 per 
share. The 4% increase to dividends was paid in 
each quarter during 2007. The 6% increase to divi-
dends will be paid each quarter in 2008.

DPL’s present summer generating capacity, includ-
ing peaking units, is approximately 3,769 MW. Of this 
capacity, approximately 2,850 MW, or 76%, is derived 
from coal-fired steam generating stations and the bal-
ance of approximately 919 MW, or 24%, consists of 
combustion turbine and diesel peaking units. 

DP&L’s present summer generating capacity, 
including peaking units, is approximately 3,285 MW. 
Of this capacity, approximately 2,850 MW, or 87%, is 
derived from coal-fired steam generating stations and 
the balance of approximately 435 MW, or 13%, con-
sists of combustion turbine and diesel peaking units. 
Combustion turbine output is dependent on ambi-

ent conditions and is higher in the winter than in the 

summer. Our all-time net peak load was 3,300 MW, 
occurring August 8, 2007. 

Approximately 87% of the existing steam generat-
ing capacity is provided by certain units owned as ten-
ants in common with Duke Energy-Ohio (or its subsid-
iaries The Cincinnati Gas & Electric Company (CG&E), 
or Union Heat, Light & Power) and AEP (or its subsid-
iary CSP). As tenants in common, each company owns 
a specified undivided share of each of these units, is 
entitled to its share of capacity and energy output and 
has a capital and operating cost responsibility propor-
tionate 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.

interchange of electricity.

In 2007, we generated 99% of our electric output from coal-fired units and 1% from oil and natural 

gas-fired units.

We have substantially all of the total expected coal volume needed to meet our retail and firm wholesale sales 
requirements for 2008 under contract. The majority of our contracted coal is purchased at fixed prices. 
Some contracts provide for periodic adjustments and some are priced based on market indices. Substantially 
all contracts have features that limit price escalations in any given year. Our sulfur dioxide (SO2) allowance 
consumption was reduced in 2007 due to the installation of emission control equipment at a portion of our genera-
tion facilities. As a result of this reduction, we will have emission allowance inventory in excess of our needs, 
which we plan to sell during 2008 and in future years. We did not purchase SO2 allowances or nitrogen oxide 
(NOx) allowances during 2007, nor do we plan to purchase any in 2008. Fuel costs are impacted by changes in 
volume and price and are driven by a number of variables including weather, reliability of coal deliveries, 
scheduled outages and generation plant mix. Based on higher volume and price, fuel costs are forecasted to be 
15% to 25% higher in 2008 compared to 2007.

The average cost of fuel used per kilowatt-hour (kWh) was as follows:

Seasonality

The power generation and delivery business is sea-
sonal and weather patterns have a material impact on 
operating performance. In the region served by our 
subsidiaries, demand for electricity is generally greater 
in the summer months associated with cooling and 
in the winter months associated with heating as com-
pared to other times of the year. Historically, the power 
generation and delivery operations of our subsidiar-
ies have generated less revenue and income when 
weather conditions are warmer in the winter and cooler 
in the summer.

Rate Regulation and Government Legislation

DP&L’s sales to retail customers are subject to rate 
regulation by the Public Utilities Commission of Ohio 
(PUCO). DP&L’s transmission and wholesale electric 
rates to municipal corporations, rural electric co-
operatives and other distributors of electric energy are 
subject to regulation by the Federal Energy Regulatory 
Commission (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 cost basis 
upon which the rates are based and other related mat-
ters. Ohio law also established the Office of the Ohio 
Consumers’ Counsel (OCC), which has the authority 
to represent residential consumers in state and federal 
judicial and administrative 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 
capitalization, among other matters, to the extent that 
they 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 consolidated 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 October 31, 2007, the Ohio Senate passed 
Senate Bill 221. The Ohio House of Representatives 
has assigned the bill to the committee and is taking 
testimony from interested parties. In its current form, 
the bill states that the standard service offer in effect 
at the end of the utility’s rate plan will remain in effect 
until the utility files either an electric security plan or a 
market rate option. Under the market rate option, the 
retail generation price will be set by a periodic com-
petitive bid process after the utility demonstrates that 
there is effective competition in its service territory and 
that it can meet other market criteria set out in the pro-
posed bill. Under the electric security plan option, the 
PUCO will establish rules for filing an electric security 
plan which may allow for adjustments to the standard 
offer for costs associated with environmental compli-
ance; fuel and purchased power; construction of new 
or investment in specified generating facilities; the 
provision of standby and default service, operating, 
maintenance, or other costs including taxes. Once an 
electric security plan is approved by the PUCO, the 
utility is required to file an infrastructure improvement 
plan that will specify the initiatives the utility will take 
to rebuild, upgrade or replace its electric distribution 
system. The proposed bill establishes a goal that by 
2025, twenty-five percent of the generation used to 
supply standard offer generation service in the state 
will come from advanced energy resources, which may 
include: sustainable resources, clean coal technol-
ogy, advanced nuclear generation, fuel cells and co-
generation of which half must be met through facilities 
located in Ohio. Full compliance with the advanced 
energy standards may not be mandated if the price 
impact of compliance exceeds three percent. The bill 
creates an advanced energy advisory committee and 
a federal energy advocate that will evaluate the costs 
and benefits associated with Regional Transmission 
Organizations (RTO) on behalf of the state. It promotes 
construction of advanced energy projects by providing 
low interest loans and grants, promotes energy efficien-
cy and requires a carbon control plan to be developed 
for each generating facility located in the state. As the 
bill is not yet in final form, the outcome of this proceed-
ing and its financial impact on the Company cannot be 
determined at this time. 

On April 4, 2005, DP&L filed a request with the 

PUCO to implement a rate stabilization surcharge 
(RSS), effective January 1, 2006, to recover cost 
increases associated with environmental capital, relat-
ed operation and maintenance costs and fuel expens-

DPL Inc.

es. Subsequently, DP&L entered into a settlement 
agreement that extended DP&L’s rate stabilization peri-
od through December 31, 2010 and allowed for recov-
ery of certain fuel and environmental investment costs 
through an environmental rider. The PUCO adopted 
the settlement, but ruled that the environmental rider 
shall be by-passable by all customers who take service 
from alternate generation suppliers. Consistent with 
the RSS Stipulation approved by the PUCO and prior 
orders, DP&L made a tariff filing that was approved by 
the PUCO in November 2006 to implement the envi-
ronmental investment rider beginning January 1, 2007. 
The case was appealed to the Ohio Supreme Court by 
the OCC. On September 5, 2007, the Ohio Supreme 
Court affirmed the PUCO’s approval of the settlement 
agreement but remanded one aspect of the order, that 
the RSS tariff should be part of the Company’s genera-
tion tariffs instead of distribution tariffs. On December 
6, 2007, DP&L filed to modify its tariffs accordingly and 
does not expect this change to impact future revenues.

Effective December 19, 2007, the PUCO issued a 
90-day moratorium on the disconnection of electric and 
natural gas services to residential customers who meet 
low-income guidelines. Under this regulation, DP&L, 
along with other Ohio electric and gas utilities, are 
prohibited from disconnecting residential customers for 
non-payment of utility bills for a 90-day period provided 
the customer agrees to enroll in the state’s low-income 
program or enter into other available payment plans. 
DP&L believes that the moratorium will not have a 
material impact on its results of operation, financial 
position or its cash flows.

Ohio Competitive Considerations and Proceedings

As of December 31, 2007, four unaffiliated market-
ers were registered as Competitive Retail Electric 
Service (CRES) providers in DP&L’s service territory. 
While there has been some customer switching to 
date associated with unaffiliated marketers, it repre-
sented less than 0.15% of sales in 2007. DPLER, an 
affiliated company, is also a registered CRES provider 
and accounted for 99.3% of the total kWh supplied by 
CRES providers within DP&L’s service territory in 2007. 
In addition, several communities in DP&L’s service 
area have passed ordinances allowing the communi-
ties to become government aggregators for the pur-
pose of offering alternative electric generation supplies 
to their citizens. To date, none of these communities 
have aggregated their generation load. 

DP&L agreed to implement a Voluntary Enrollment 

Program (VEP) that would provide customers with an 
option to choose a competitive supplier to provide 

their retail generation service should switching not 
reach 20% in each customer class. The 20% threshold 
has never been reached. Customers who elected to 
participate in the program were grouped together and 
collectively bid out to CRES providers. Four rounds of 
bidding were conducted for the 2007 program result-
ing in no bids being received. DP&L has completed its 
obligations under this program.

Other State Regulatory Proceedings

On August 28, 2006, the Staff of the PUCO issued a 
report relating to compliance with the Federal Energy 
Policy of 2005. In that report the Staff makes recom-
mendations to the Commission to implement new rules 
and procedures relating to net metering, customer 
generator interconnection, stand by power, time-of-
use rates, and renewable energy portfolio standards. 
DP&L, among others, filed comments and reply com-
ments. In 2007, the Commission held a series of tech-
nical conferences on automated meter infrastructure, 
interconnection, net metering, and standby power 
rates. On December 21, 2007, DP&L filed a series of 
tariffs to comply with this rule making. The potential 
cost associated with new regulations from these pro-
ceedings cannot be quantified at this time. 

On April 3, 2007, the PUCO issued proposed revi-

sions to the Commission’s minimum electric service 
and safety standards. These rules govern a variety of 
utility operations such as maintenance programs, new 
construction, meter reading, and distribution circuit 
performance. The proposed changes impact customer 
service requirements, reliability reporting and distribu-
tion inspection and maintenance programs, as well as 
increase the penalty the Commission may invoke if a 
utility is found to be in violation of these rules. DP&L, 
among others, filed comments and reply comments. 
DP&L may experience an increase in distribution 
operation and maintenance expense associated with 
the new rules. We are unable to determine the potential 
financial impact of these changes at this time.

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 

10  DPL Inc.

the state’s investor-owned utilities are required to join 
an RTO. In October 2004, DP&L successfully inte-
grated its 1,000 miles of high-voltage transmission into 
the PJM Interconnection, L.L.C. (PJM) RTO. The role of 
the RTO is to administer an electric marketplace 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.

As a member of PJM, DP&L is subject to charges 

and costs associated with PJM operations as approved 
by the FERC. On April 19, 2007, the FERC issued an 
order that modified the traditional method of allocating 
costs associated with new high voltage planned trans-
mission facilities. FERC ordered that the cost of new, 
high-voltage facilities be socialized across the PJM 
region. The costs of the new facilities at lower voltages 
will continue to be assigned to the load centers that 
benefit from the new facilities. In a companion order 
also issued on April 19, 2007, FERC did not change 
the existing allocation of costs associated with exist-
ing transmission facilities, upholding the existing PJM 
rate design. On February 1, 2008, FERC issued an 
order on rehearing that upheld its original decision. The 
overall impact of FERC’s orders cannot be definitively 
assessed at this time because not all new planned 
construction is likely to happen. The additional costs 
allocated to the Company for new large transmis-
sion approved projects are expected to be immate-
rial in 2008 and 2009 but could rise to approximately 
$12 million or more annually by 2012. As a result, on 
December 21, 2007, DP&L filed an application seeking 
PUCO authority to defer costs associated with these 
new high-voltage transmission projects for future recov-
ery through retail rates.

As a member of PJM, the value of DP&L’s gen-
eration capacity is affected by changes in and the 
clearing results of the PJM capacity construct. The 
construct utilizes a Reliability Pricing Model (RPM) that 
changes the way generation capacity is priced and 
planned for by PJM. PJM held its first RPM auction 
during April 2007 for the 2007/2008 planning year and 
held subsequent auctions during July and October 
2007 and January 2008. The results of these auctions 
have not had a material impact on our results of opera-

tions, financial position or cash flows. The FERC deci-
sions establishing RPM have been appealed by vari-
ous entities to the Federal appeals court. RPM remains 
in effect pending the outcome of the appeal. DP&L has 
intervened and supports the FERC decisions.

In connection with DP&L and other utilities join-
ing PJM, the FERC ordered utilities to eliminate certain 
charges to implement transitional payments, known 
as Seams Elimination Charge Adjustment (SECA), 
effective December 1, 2004 through March 31, 2006, 
subject to refund. Through this proceeding, DP&L 
was obligated to pay SECA charges to other utilities, 
but received a net benefit from these transitional pay-
ments. The hearing was held in May 2006 and an 
initial decision was issued on August 10, 2006 that, 
if upheld by the FERC, would reduce the amount of 
SECA charges DP&L and other parties are permitted 
to recover. DP&L, among others, has taken exception 
to the initial decision. A final FERC order on this issue 
is still pending. We have entered into a significant 
number of bi-lateral settlement agreements with certain 
parties to resolve the matter, which by design will be 
unaffected by the FERC’s decision to affirm, modify or 
reject the initial decision. DP&L management believes 
that appropriate reserves have been established in the 
event that SECA collections not resolved by settlement 
are required to be refunded. The ultimate outcome of 
the proceeding establishing SECA rates is uncertain at 
this time. However, based on the amount of reserves 
established for this item, the results of this proceeding 
are not expected to have a material adverse effect on 
DP&L’s results of operations. 

On August 8, 2005, the Energy Policy Act of 2005 
(the 2005 Act) was enacted. This new law encompass-
es several areas including, but not limited to: electric 
reliability, repeal of the Public Utility Holding Company 
Act of 1935, promotion of energy infrastructure and 
preservation of a diverse fuel supply for electricity 
generation and energy efficiency. In response to the 
2005 Act, the FERC issued a Notice of Proposed 
Rulemaking to amend its regulations to incorporate the 
criteria which an entity must satisfy in order to qualify 
to be an Electric Reliability Organization (ERO). Part 
of the ERO’s goals is to propose and enforce reliability 
standards subject to FERC approval. The proposed 
rule also included related matters on delegating 
ERO authority, the creation of advisory bodies and 
reporting requirements. 

In October 2006, the FERC also approved new 
mandatory reliability standards which become effective 
in 2007, with requirements applying to certain assets 
and activities of DPL, DP&L and DPLE. FERC subse-

DPL Inc. 

11

 
quently has promulgated some revisions and additional 
reliability standards, including cyber-security stan-
dards. The new regulations include potential penalties 
for failure to comply with these standards. DPL, DP&L 
and DPLE are currently assessing and modifying com-
pliance documents and procedures as needed. We are 
working with consultants, other utilities and other orga-
nizations to comply with the new mandatory standards 
and their compliance documentation requirements. 

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 2007 represented sales to 
these municipalities.

On September 28, 2007, the Internal Revenue 

Service (IRS) published proposed regulations which 
would change the treatment of transactions involv-
ing the provision of insurance between members of 
a consolidated tax group. If adopted, these regula-
tions would affect the tax position previously held by 
Miami Valley Insurance Company (MVIC), our captive 
insurance company that provides insurance to us 
and our subsidiaries. The IRS requested comments 
by December 27, 2007. MVIC filed comments as part 
of a coalition formed for this purpose which included 
captive insurance companies and parent companies, 
captive insurance industry associations and insurance 
departments of numerous states which have captive 
insurance regulations. These entities all oppose the 
IRS’ proposed regulations. The IRS will review all com-
ments received and may publish a final regulation in 
the same form, or may substantially change or aban-
don its proposed regulation. Since we do not know 
what steps the IRS will take, we cannot predict the 
impact on DPL, DP&L or MVIC at this time. 

Environmental Considerations

DPL, DP&L and our subsidiaries’ facilities and opera-
tions are subject to a wide range of environmental reg-
ulations and laws by federal, state and local authorities. 
The environmental issues that may impact us include:

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

■ Litigation with the federal and certain state govern-
ments and certain special interest groups regarding 

whether modifications to or maintenance of certain 
coal-fired generating plants required additional permit-
ting or pollution control technology, and/or whether 
emissions from coal-fired generating plants cause or 
contribute to global climate changes.

■ Rules issued by the United States Environmental 
Protection Agency (USEPA) and Ohio Environmental 
Protection Agency (Ohio EPA) that require substantial 
reductions in SO2, mercury and NOx emissions. 
DPL is installing (and has installed) emission control 
technology and is taking other measures to comply 
with required reductions.

■ The Federal Clean Water Act (FCWA), which prohib-
its the discharge of pollutants into waters of the United 
States except pursuant to appropriate permits. In July 
2004, the USEPA adopted a new Clean Water Act rule 
to reduce the number of fish and other aquatic organ-
isms killed by discharges from cooled power plants.

■ Solid and hazardous waste laws and regulations, 
which govern the management and disposal of cer-
tain waste. The majority of solid waste created from 
the combustion of coal and fossil fuels is fly ash and 
other coal combustion by-products, which the EPA has 
determined are not hazardous waste subject to the 
Resource Conservation and Recovery Act (RCRA).

As well as imposing continuing compliance obliga-
tions, these laws and regulations authorize the impo-
sition of substantial penalties for noncompliance, 
including fines, injunctive relief and other sanctions. 
In the normal course of business, we have investiga-
tory and remedial activities underway at these facili-
ties to comply, or to determine compliance, with such 
regulations. We record liabilities for probable esti-
mated loss in accordance with Statement of Financial 
Accounting Standards No. 5 (SFAS 5) “Accounting for 
Contingencies,” as discussed in Note 1 of the Notes 
to Consolidated Financial Statements. DPL, through its 
wholly-owned captive insurance subsidiary MVIC, has 
an actuarially calculated reserve for environmental 
matters. We evaluate the potential liability related to 
probable losses quarterly and may revise our esti-
mates. Such revisions in the estimates of the potential 
liabilities could have a material effect on our results of 
operations, financial position or cash flows.

In addition to the requirements related to emis-
sions of SO2, mercury, and NOx noted above, there 
is a growing concern nationally and internationally 
about global climate change and the contribution of 
emissions of greenhouse gases, including most signifi-
cantly, carbon dioxide (CO2). This concern has led to 

12  DPL Inc.

increased interest in legislation at the federal level and 
actions at the state level as well as litigation relating 
to greenhouse gas emissions, including a recent U.S. 
Supreme Court decision holding that the USEPA has 
the authority to regulate carbon dioxide emissions from 
motor vehicles under the CAA. Increased pressure 
for carbon dioxide emissions reduction also is coming 
from investor organizations and the international 
community. Environmental advocacy groups are also 
focusing considerable attention on carbon dioxide 
emissions from power generation facilities and their 
potential role in climate change. Although several bills 
have been introduced in Congress that would compel 
CO2 emission reductions, no bills have passed to date. 
Future changes in environmental regulations governing 
these pollutants could make some of our electric 
generating units uneconomical to maintain or oper-
ate. In addition, any legal obligation that would require 
extensive mitigation efforts and, in the case of CO2 
legislation, would raise uncertainty about the future 
viability of fossil fuels, particularly coal, as an energy 
source for new and existing electric generation facili-
ties. If legislation or regulations are passed at the 
federal or state levels imposing mandatory reductions 
of carbon dioxide and other greenhouse gases 
on generation facilities, the cost to DPL and DP&L of 
such reductions could be material.

Environmental Regulation and Litigation 
Related to Air Quality 

Regulation Proceedings – Air

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. Subsequently, 
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 law-
suits filed by numerous states and environmental orga-
nizations challenging the final rules. As a result of the 
stay, the Ohio EPA delayed its previously announced 
intent to adopt the RMRR rule. On October 20, 2005, 

USEPA proposed to revise the emissions test for 
existing electric generating units. At this time, we are 
unable to determine the impact of the ERP appeal or 
the outcome of the proposed emissions test.

In a regulation proceeding relating to the same 
issue decided by the U.S. Supreme Court in the Duke 
Energy case discussed below, the USEPA issued a 
proposed rule in October 2005 concerning the test for 
measuring whether modifications to electric generating 
units should trigger application of New Source Review 
(NSR) standards under the CAA. The proposed rule 
seeks comments on two different hourly emissions 
test options as well as the USEPA’s current method of 
measuring previous actual emission levels to projected 
actual emission levels after the modification. A third 
option that tests emissions increase based upon emis-
sions per unit of energy output is also available for 
comment. We cannot predict the outcome of this rule-
making or its impact on current environmental litigation. 
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 Clean Air Interstate Rule (CAIR). 
The final rules were signed on March 10, 2005 and 
were published on May 12, 2005. On August 24, 2005, 
the USEPA proposed additional revisions to the CAIR 
and initiated reconsideration on one issue. Although 
we cannot predict the outcome of the reconsideration 
proceedings, the petitions or the pending litigation, 
CAIR has had and will have a material effect on our 
operations. Phase I CAIR requirements tend to promote 
decisions to install FGD equipment and continuous 
operation of the currently installed Selective Catalytic 
Reduction equipment. In 2007, the Ohio EPA revised 
their State Implementation Plan (SIP) to incorporate a 
CAIR program consistent with the IAQR. The Ohio EPA 
is awaiting approval from the USEPA. Upon approval, 
the USEPA will distribute related CAIR NOx seasonal 
and annual emission allowances. As a result, DP&L 
has installed FGD equipment at the Killen generating 
station and is proceeding with the installation of FGD 
equipment at the Stuart generating station.

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-

DPL Inc. 

13

 
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 USEPA, opposing the 
cap-and-trade regulatory approach taken by USEPA. 
In 2007, the Ohio EPA adopted rules implementing the 
CAMR program. On February 8, 2008, the Court of 
Appeals struck down the USEPA regulations, finding 
that the USEPA had not complied with statutory require-
ments applicable to “de-listing” a hazardous air pollut-
ant and that a cap-and-trade approach was not autho-
rized by law for “listed” hazardous air pollutants. The 
order is subject to appeal to the U.S. Supreme Court 
which has a discretionary power to decide whether or 
not to hear an appeal. 

Due to the ongoing uncertainties associated with 

an appeal that may be taken to the U.S. Supreme 
Court and the USEPA regulatory process if the D.C. 
Circuit’s ruling is not reversed, we cannot project the 
final costs we may incur to comply with any resulting 
mercury restriction regulations.

On July 15, 2003, the Ohio EPA submitted to the 

USEPA its recommendations for eight-hour ozone non-
attainment boundaries for the metropolitan areas within 
Ohio. On April 15, 2004, the USEPA issued its list of 
ozone non-attainment designations. Since these initial 
designations, the Ohio EPA has recommended that 
nine areas designated non-attainment be designated 
as attainment. Currently USEPA has redesignated eight 
of those areas as attainment for the eight-hour ozone 
national ambient air quality standards, including coun-
ties where DP&L owns and/or operates a number of 
facilities. In redesignating these counties as attainment, 
the Ohio EPA submitted and USEPA approved amend-
ments to the SIP that include maintenance plans for 
these areas. In June 2007, the Ohio EPA submitted a 
plan to USEPA for attaining the eight-hour ozone stan-
dard for the Cincinnati-Hamilton area in which DP&L 
owns a number of facilities. DP&L cannot determine 
the outcome of this redesignation effort at this time.

On January 5, 2005, the USEPA published its final 

non-attainment designations for the national ambient 
air quality standard for Fine Particulate Matter 2.5 (PM 
2.5). These designations included counties and partial 
counties in which DP&L operates and/or owns gen-
erating 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 creating these designations. 

On November 30, 2005, the court ordered USEPA to 
decide on all petitions for reconsideration by January 
20, 2006. On January 20, 2006, USEPA denied the 
petitions for reconsideration. The court ordered a brief-
ing schedule with final briefs due in July 2008 and oral 
arguments to be scheduled for fall 2008. The Ohio 
EPA must submit regulations to attain and maintain 
compliance with the PM 2.5 national ambient air qual-
ity standard in April 2008. DP&L cannot determine the 
outcome of the petition for review or the effect such 
Ohio EPA regulations will have on its 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, 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. 

Sierra Club Litigation

On April 2, 2007, the U.S. Supreme Court unanimously 
overturned the rulings of two lower courts and con-
cluded that the CAA’s NSR requirements are triggered 
when a major physical or operational change at a facil-
ity results in an increase in the facility’s annual emis-
sions (Environmental Defense et al. v. Duke Energy 
Corp. et al.). The outcome of this case is significant to 
DP&L because it eliminates one of DP&L’s major argu-
ments in the lawsuit filed against it by the Sierra Club. 
The Court decided that an annual rate of emissions 
could be used to determine if major modifications have 
been made to a plant as opposed to an hourly emis-
sion rate as Duke had argued. Using the annual rate 
makes it more likely that most plant modifications will 
be found to be “major” modifications, thus requiring 
EPA permits. DP&L can still defend against the allega-
tions of NSR violations if it can establish that the activi-
ties at issue did not cause total annual emissions to 
increase or that the projects that resulted in increased 
emissions were undertaken for routine maintenance, 
repair and replacement activities.

In September 2004, the Sierra Club filed a lawsuit 
against us and the other owners of the Stuart generat-
ing station in the United States District Court for the 
Southern District of Ohio for alleged violations of the 
CAA, including issues similar to those presented in the 

14  DPL Inc.

Duke Energy case and other issues relating to alleged 
violations of opacity limitations. DP&L, on behalf 
of all co-owners, is leading the defense of this mat-
ter. A sizable amount of discovery has taken place 
and expert reports were filed at various times from 
May through September 2007. On February 14, 2008, 
upon the request of the Sierra Club, DP&L and the 
other owners of the Stuart generating station, the Court 
approved another sixty day stay of proceedings 
to permit the parties the opportunity to determine if a 
settlement of the case could be reached. Settlement 
negotiations are ongoing.

Litigation Involving Co-Owned Plants

In March 2000, as amended in June 2004, the United 
States Department of Justice filed a complaint in an 
Indiana federal court 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). The defense is being led by 
Duke Energy and a trial is currently scheduled to begin 
later in 2008.

In November 2004, the State of New York and 
seven other states filed suit against AEP and vari-
ous subsidiaries, alleging various CAA violations at a 
number of AEP electric generating facilities, including 
Conesville Unit 4 co-owned by CG&E, DP&L and CSP. 
AEP settled this case on October 9, 2007 and DP&L 
will be required to pay approximately $0.5 million for 
its partial ownership of Conesville Unit 4. 

In November 2004, various residents of the Village 

of Moscow, Ohio sued CG&E, as the operator of 
Zimmer generating station (co-owned by CG&E, DP&L 
and CSP), for alleged violations of the CAA and air 
pollution nuisances. CG&E, on behalf of all co-owners, 
is leading the defense of this matter.

Notices of Violation Involving Co-Owned Plants

In June 2000, the USEPA issued a Notice of Violation 
(NOV) to 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 
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.

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. DP&L was not identified in the NOVs, 
civil complaints or state actions. 

In December 2007, the Ohio EPA issued a NOV to 

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 continuous 
monitoring of opacity. A compliance plan has been 
submitted to the Ohio EPA. To date, no further actions 
have been taken by the Ohio EPA.

Other Issues Involving Co-Owned Plants

In 2006, DP&L detected a malfunction with its emis-
sion monitoring system at 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, finan-
cial position or cash flows. 

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 and Ohio 
EPA and DP&L has provided data to those agencies 
regarding its maintenance expenses and operating 
results. DP&L is unable to determine whether any addi-
tional actions will take place with respect to this matter.

Environmental Regulation and Litigation 

Related to 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 

DPL Inc. 

15

 
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 USEPA for 
reconsideration. We are undertaking studies at two 
facilities but cannot predict the impact such studies 
may have on future operations or the outcome of the 
remanded rulemaking.

On May 4, 2004, the Ohio EPA issued a final 
National Pollutant Discharge Elimination System per-
mit (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 intend 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. The two diffuser options identified by 
Ohio EPA could cost approximately $33 million based 
on preliminary cost estimates, of which our pro-rata 
share would be approximately $11.5 million. We have 
not seen the compliance schedule and cannot predict 
the final outcome of this issue on future operations. 

Environmental Regulation and Litigation Related to 

Land Use and Solid Waste Disposal

DP&L has been identified, either by a government 
agency or by a private party seeking contribution to 
site clean-up costs, as a Potentially Responsible Party 
(PRP) at two sites pursuant to state and federal laws. 
In September 2002, DP&L and other parties 
received a special notice that the USEPA considers us 
to be PRPs 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 
regarding 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 negotia-
tions with USEPA to conduct the RI/FS. Information 
available to DP&L does not demonstrate that it contrib-
uted hazardous substances to the site. Should USEPA 
pursue a civil action, DP&L will vigorously challenge it. 

In December 2003, DP&L and other parties 

received a special notice that the USEPA considers us 
to be PRPs 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.

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.

In August 2006, Ohio EPA issued draft rules for 
interested party comment related to the disposal of 
industrial waste. DP&L, through the Ohio Electric Utility 
Institute submitted comments on the draft rules. 
DP&L cannot predict the impact of the draft rules on 
future operations.

Capital Expenditures for Environmental Matters

DPL’s construction additions were approximately $347 
million, $352 million and $180 million in 2007, 2006 
and 2005, respectively, and are expected to approxi-
mate $205 million for 2008. DP&L’s construction 
additions were approximately $344 million, $349 million 
and $178 million in 2007, 2006 and 2005, respectively. 
Planned construction additions of DP&L for 2008 
are expected to approximate $203 million and relate 
to DP&L’s environmental compliance program, power 
plant equipment, and its transmission and distribution 
system. All environmental additions made during the 
past three years pertain to DP&L and approximate 
$206 million, $246 million and $90 million in 2007, 
2006 and 2005, 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 oral or written 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 

16  DPL Inc.

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 state-
ments are identified by terms and phrases such as 
“anticipate,” “believe,” “intend,” “estimate,” “expect,” 
“continue,” “should,” “could,” “may,” “plan,” “project,” 
“predict,” “will” and similar expressions.

The following is a listing of risk factors that DPL 

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

Regulatory Environment 

We operate in a rapidly changing industry with evolv-
ing industry standards and regulations. In recent years 
a number of federal and state developments aimed at 
promoting competition triggered industry restructuring. 
Regulatory factors, such as changes in the policies 
and procedures that set rates; changes in tax laws, tax 
rates and environmental laws and regulations; changes 
in DP&L’s ability to recover expenditures for environ-
mental compliance, fuel and purchased power costs 
and investments made under traditional regulation 
through rates; and changes to the frequency and tim-
ing of rate increases could affect our results of opera-
tions, financial condition or cash flows. Additionally, 
financial or regulatory accounting principles or policies 
imposed by governing bodies can increase our 
operational, monitoring and information technology 
costs affecting our results of operations and financial 
condition.

Before 2001, electric utilities provided electric 
generation, transmission and distribution services as a 
single product to retail customers at prices set by the 
PUCO. In 1999, Ohio enacted legislation that partially 
deregulated utility service, effective January 1, 2001, 
making retail generation service a competitive service. 
Customers may choose to take generation service from 
CRES providers that register with the PUCO but are 
otherwise unregulated. In connection with this deregu-
lation of the electric industry in Ohio, electric utilities 
have had to restructure their service and their rates to 
accommodate competition. 

Many of the requirements of the Ohio deregulation 

law were premised on the assumption that the whole-
sale generation market and, in turn, the retail genera-
tion market, would fully develop by the end of 2005, 
and that the price for generation for even those 
customers who choose to continue to purchase the 
service from the regulated utility would be set purely 
by the market. That did not occur. As a result, the 

PUCO and the utilities, including DP&L, have worked 
out plans to provide market-based pricing for genera-
tion service, but also to stabilize those rates for several 
years. What DP&L may propose and what the PUCO 
will approve in the future regarding pricing and cost 
recovery will depend on the degree to which the whole-
sale and retail electric generation markets have devel-
oped and the final outcome of the pending energy 
legislation in Ohio. 

On September 25, 2007, Senate Bill 221 was intro-
duced in the Ohio Legislature. The bill codifies, in draft 
form, the governor’s proposed energy policy. The bill 
was passed by the Senate on October 31, 2007. The 
Ohio House of Representatives has assigned the bill 
to committee and is taking testimony from interested 
parties. As the bill is not yet in final form, the outcome 
of this proceeding and its financial impact on the 
Company cannot be determined at this time.

Customer Switching 

Changes in our customer base, including government 
aggregation, could lead to the entrance of competitors 
in our marketplace, affecting our results of operations, 
financial condition or cash flows. Although retail gen-
eration service has been a competitive service since 
January 1, 2001, the competitive generation market 
has not developed in DP&L’s service territory to any 
significant degree. The following are factors that could 
result in increased switching by customers to CRES 
providers in the future:

■ DP&L’s Standard Service Offer

The RSS Stipulation discussed above, permits custom-
ers that take service from a CRES provider to bypass 
the Environmental Investment Rider (EIR). Because 
this charge increases each year, the price that a CRES 
provider can offer to save customers money changes 
each year. Depending on the development of the 
wholesale market and the level of wholesale prices, 
CRES providers could become more active in DP&L’s 
service territory.

■ CRES Supplier Initiatives 

Customers can elect to take generation service from 
a CRES provider offering services to customers in 
DP&L’s service territory. As of December 31, 2007, five 
CRES providers have been certified by the PUCO to 
provide generation service to DP&L customers. One 
of those five, DPL Energy Resources, Inc. (DPLER), is 
a wholly-owned affiliate of DPL. Although DPLER sup-
plied 99.3% of the total kWh consumed by customers 
served by CRES providers in DP&L’s service territory 
in 2007, at the end of 2007 there was a slight increase 

DPL Inc. 

17

 
in the non-residential customers served by unaffiliated 
CRES providers. There has been no residential custom-
er switching to date. Depending on the development of 
the wholesale market and the level of wholesale prices, 
CRES providers could become more active in DP&L’s 
service territory and may begin to offer prices lower 
than DP&L’s standard offer. This could result in more 
switching by DP&L’s customers and a further loss of 
revenues by DP&L. 

■ Governmental Aggregation Programs

Another way in which DP&L could experience cus-
tomer switching is through “governmental aggrega-
tion.” Under this program, municipalities 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 have 
passed ordinances allowing them to become govern-
ment aggregators. Although none has yet implemented 
an aggregation program, that too, could change 
provided CRES providers offer prices below DP&L’s 
standard offer. 

Risks Associated with Our Pre-determined Rates 

DP&L has provided service at rates governed by the 
PUCO-approved transition, market development and 
rate stabilization plans. Those rates have included a 
statutorily-required 5% rate reduction in the genera-
tion component of its residential rates, a further 2.5% 
reduction to the residential generation rate through 
2008, fixed generation rates through December 31, 
2010, and frozen distribution rates through December 
31, 2008. The protection afforded by retail fuel clause 
recovery mechanisms was eliminated effective January 
1, 2001 by the implementation of customer choice in 
Ohio. Likewise, through the RSS Stipulation, DP&L 
extended its commitment to maintain pre-determined 
rates for generation through December 31, 2010, and 
in exchange is permitted to charge two new rate rid-
ers to offset increases in fuel and environmental costs. 
Beginning January 1, 2006, a RSS was implemented 
that recovered approximately $65 million additional rev-
enue in 2006, net of customer discounts. The EIR could 
result in approximately $35 million additional revenue 
each year, net of customer discounts and assuming 
insignificant levels of customer switching. The PUCO 
ruled this rider will be bypassable by all customers 
who take service from alternative generation suppli-
ers. Accordingly, the rates DP&L is allowed to charge 
may or may not match its expenses at any given time. 
Therefore, during this period (or possibly earlier by 
order of the PUCO), while DP&L will be subject to pre-
vailing market prices for electricity, it would not neces-

sarily be able to charge rates that produce timely or full 
recovery of its expenses. DP&L has historically main-
tained its rates at consistent levels since 1994, when 
the final phase of DP&L’s last traditional rate case 
was implemented. However, as DP&L operates under 
its PUCO-approved RSS Stipulation, there can be no 
assurance that DP&L would be able to timely or fully 
recover unanticipated levels of expenses, including but 
not limited to those relating to fuel, coal and purchased 
power, compliance with environmental regulation, reli-
ability initiatives and capital expenditures for the main-
tenance or repair of its plants or other properties. 

Commodity Prices

The supply and price of fuel and other commodities 
may impact our financial results. We are dependent 
on coal for much of our electrical generating capac-
ity. Price fluctuations and fuel supply disruptions could 
have a negative impact on our ability to profitably gen-
erate electricity. The price for most solid fuels generally 
has been increasing. Management has responded to 
increases in the price of coal by entering into contracts 
to hedge our exposure to fuel requirements and other 
energy-related commodities. We may not be able to 
hedge the entire exposure of our operations from com-
modity price volatility. To the extent we are not able to 
hedge against price volatility, our results of operations, 
financial position or cash flows could be negatively 
affected. We have contracts of varying durations for 
the supply of coal for most of our existing generation 
capacity, but as these contracts end or otherwise are 
not honored, we may not be able to purchase coal on 
favorable terms. If we are unable to secure adequate 
coal supplies in a timely manner, either due to the fail-
ure of our suppliers to deliver the contracted commod-
ity or the inability to secure additional quantities, our 
results of operations, financial condition or cash flows 
may be adversely impacted.

Regional Transmission Organizational Risks

On October 1, 2004, in compliance with Ohio law, 
DP&L turned over control of its transmission functions 
and fully integrated into PJM. The price at which DPL 
and DP&L can sell its generation capacity and energy 
is now more dependent upon the overall operation 
of the PJM market. While DP&L can continue to make 
bi-lateral transactions to sell its generation through 
a willing-buyer and willing-seller relationship, any 
transactions that are not pre-arranged are subject to 
market conditions at PJM. The rules governing the vari-
ous regional power markets also change from time to 
time which could affect DP&L’s costs and revenues. 
DP&L incurs fees and costs to participate in the RTO. 

18  DPL Inc.

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 DP&L. Likewise, 
in December 2006, FERC approved PJM’s RPM. RPM 
became effective in 2007 and provides forward and 
locational pricing for generation capacity. The finan-
cial impact of RPM on DP&L will depend on a variety 
of factors, including the market behavior of various 
participants. The RPM auctions have been held for 
the 2007/2008 through 2010/2011 delivery years. At 
this time, these auction results are expected to have 
no material financial impact to DPL. Because the RTO 
market rules are continuing to evolve, we cannot fully 
assess the impact that these power markets or other 
ongoing RTO developments may have on DP&L.

As a member 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.

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 assigned to the load centers that benefit from the 
new facilities. In a companion order also issued on 
April 19, 2007, FERC did not change the existing allo-
cation of costs associated with existing transmission 
facilities, upholding the existing PJM rate design. The 
overall impact of FERC’s orders cannot be definitively 
assessed at this time because not all new planned 

construction is likely to happen. The additional costs 
allocated to the Company for new large transmission 
approved projects are expected to be immaterial in 
2008 and 2009 but could rise to approximately $12 mil-
lion or more annually by 2012. As a result, DP&L filed 
an application seeking PUCO authority to defer costs 
associated with these new high-voltage transmission 
projects for future recovery through retail rates.

Reliance on Third Parties

We rely on many suppliers for the purchase and deliv-
ery of inventory, including coal and equipment compo-
nents, to operate our energy production, transmission 
and distribution functions. Unanticipated changes in 
our purchasing processes, delays and supplier avail-
ability may affect our business and operating results. In 
addition, we rely on others to provide professional ser-
vices, such as, but not limited to, actuarial calculations, 
internal audit services, payroll processing and various 
consulting services.

Historically, some of our coal suppliers have not 
performed their contracts as promised and have failed 
to timely deliver all coal as specified under their con-
tracts. Such failure could significantly reduce DP&L’s 
inventory of coal and may cause DP&L to purchase 
higher priced coal on the spot market. When the fail-
ure is for a short period of time, DP&L can absorb the 
irregularity due to existing inventory levels. If we are 
required to purchase coal on the spot market, it may 
affect our cost of operations.

DP&L is a co-owner in certain generation facilities 

where it is a non-operating partner. DP&L does not 
procure the fuel for these facilities. Partner operated 
facilities do not always have realized coal costs that 
are equal to our co-owners’ projections.

Greenhouse Gas Emissions and Climate Change

Recently we have seen a growing interest in consider-
ing legislation or regulation in response to greenhouse 
gases generated by numerous sources, vehicles, 
manufacturing and the electric utility industry. Although, 
DPL, DP&L and its subsidiaries have operated facili-
ties in compliance with state and federal environmental 
laws and regulations and are currently engaged in sig-
nificant capital improvements of four units at the Stuart 
generating station for the reduction of SO2, Congress 
or the State of Ohio could approve legislation or regula-
tions that in the long term may impact operations of the 
units we and our partners manage or increase the cost 
for us to do so. 

Greenhouse gas (GHG) emissions, consisting 

primarily of carbon dioxide emissions, are presently 
unregulated. Numerous bills have been introduced in 

DPL Inc. 

19

 
Congress to regulate GHG emissions, but to date none 
have been passed. Future regulation of GHG emis-
sions is uncertain. However, such regulation would 
be expected to impose costs on our operations. Such 
costs could include measures as advanced by various 
constituencies, including a carbon tax; investments in 
energy efficiency; installation of CO2 emissions control 
technology, to the extent such technology exists; pur-
chase of emission allowances, should a trading mech-
anism be developed; or the use of higher-cost, lower 
CO2 emitting fuels. Costs of compliance with these 
proposed environmental regulations could adversely 
affect our results of operations and financial posi-
tion, especially if emission and/or discharge limits are 
tightened, more extensive permitting requirements are 
imposed, additional substances become regulated and 
the number and types of assets we operate increase. 
All of our estimates are subject to significant uncertain-
ties about the outcome of several interrelated assump-
tions and variables, including timing of implementation, 
required levels of reductions, allocation requirements 
of the new rules and our selected compliance alterna-
tives. As a result, we cannot estimate our compliance 
cost with certainty. The actual cost to comply could 
differ materially from the estimates. We will continue to 
evaluate investments in energy efficiency that reduce 
our GHG emissions.

Environmental Compliance

Our facilities (both wholly-owned and co-owned with 
others) are subject to continuing federal and state envi-
ronmental laws and regulations. We own a non-con-
trolling, minority interest in several generating stations 
operated by CG&E or its affiliate, Union Heat, Light 
& Power, and CSP. Either or both of these parties are 
likely to take steps to ensure that these stations remain 
in compliance with applicable environmental laws 
and regulations. As a non-controlling owner in these 
generating stations, we will be responsible for our pro 
rata share of these expenditures based upon our 
ownership interest.

Flue Gas Desulfurization Project

We have constructed or are currently constructing 
flue gas desulfurization (FGD) facilities at four units 
located at our J. M. Stuart electric generating station. 
Construction of the FGD facilities at each unit was 
completed or is scheduled to be completed in 2008. 
We are also co-owners of electric generating stations 
operated by other investor-owned utilities, who are in 
various stages of constructing FGD facilities at these 
stations. Significant construction delays could adverse-
ly affect our ability to operate or may substantially 

increase our cost to operate these electric generating 
stations under federal environmental laws and regula-
tions that become effective in 2010. For those electric 
generating stations where we are co-owners but do not 
operate, significant construction delays may substan-
tially increase our pro rata share of the cost to operate 
those facilities beginning in 2010.

Our Stock Price May Fluctuate

The market price of DPL’s common stock has fluctu-
ated over a wide range. In addition, the stock market 
in recent years has experienced significant price and 
volume variations that have often been unrelated to 
our operating performance. Over the past three years, 
the market price of our common stock has fluctuated 
with a low of $24.08 and a high of $31.91. The market 
price of our common stock may continue to fluctuate 
in the future and may be affected adversely by factors 
such as actual or anticipated changes in our operat-
ing results, acquisition activity, changes in financial 
estimates by securities analysts, general market condi-
tions, rumors and other factors.

Economic Conditions

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 commer-
cial customers.

DPL and DP&L’s results of operations may be 
negatively affected by sustained downturns or a slug-
gish economy, all of which are beyond our control. 
Sustained downturns or a sluggish economy generally 
affect the markets in which DP&L operates and nega-
tively influences DP&L’s energy operations. A falling, 
slow or sluggish economy could reduce the demand 
for energy in areas in which we are doing business. 
Our commercial and industrial customers use our ener-
gy in the production of their products. During economic 
downturns, these 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 
for production.

Credit Crisis

The current global credit crisis may adversely affect 
our business and financial results. During 2007, higher 
interest rates, falling property prices and a signifi-
cant increase in the number of sub-prime mortgages 
originated in 2005 and 2006 contributed to dramatic 
increases in mortgage delinquencies and defaults in 
2007. The anticipated future delinquencies among 

20  DPL Inc.

high-risk, or sub-prime, borrowers in the United States 
is expected to continue in the foreseeable future. 
The widespread dispersion of credit risk related to 
mortgage delinquencies and defaults through the 
securitization of mortgage-backed securities, sales of 
collateralized debt obligations (CDOs) and the creation 
of structured investment vehicles (SIVs), as well as the 
unclear impact on large banks of mortgage-backed 
securities, CDOs and SIVs, caused banks to reduce 
their loans to each other or make them at higher inter-
est rates. Similarly, the ability of corporations to obtain 
funds through the issuance of debt was negatively 
impacted. We issue debt to cover the costs of certain 
of our operations and expenditures and the inability 
to issue such debt on reasonable terms or at all could 
negatively affect our business.

On November 14th, 2007 the OAQDA issued $90 
million of collateralized, variable rate revenue bonds, 
2007 Series A due November 1, 2040 (the Series A 
Revenue Bonds). In turn, DP&L borrowed these funds 
from the OAQDA. The Series A Revenue Bonds are 
auction rate bonds. Every 35 days, the bonds are 
offered for sale to the market. The auction process 
sets the interest rate for the upcoming holding period 
by selling the bonds to the purchasers who bid to pur-
chase the bonds at the lowest interest rate. A credit 
enhancement feature of the Series A Revenue Bonds 
is the insurance policy issued by Financial Guaranty 
Insurance Company (FGIC), which insures principal 
and interest payments on the Series A Revenue Bonds 
when such payments are due. FGIC’s credit rating was 
recently downgraded by Fitch Ratings and Standard 
& Poor’s from AAA to AA, and by Moody’s from Aaa to 
A3. The current credit crisis and economic conditions, 
along with FGIC’s recent credit rating downgrades, has 
resulted in fewer investors participating in the auction 
process for the Series A Revenue Bonds, which has 
resulted in increased interest rates on the Series A 
Revenue Bonds.

Operating Results Fluctuations 

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; 
unusual maintenance or repairs; changes in fuel and 
purchased power costs, emissions allowance costs, or 
availability constraints; environmental compliance; and 
electric transmission system constraints.

Regulatory Uncertainties and Litigation

In the normal course of business, we are subject to 
various lawsuits, actions, proceedings, claims and 

other matters asserted under laws and regulations. 
Additionally, we are subject to diverse and complex 
laws and regulations, including those relating to corpo-
rate governance, public disclosure and reporting, and 
taxation, which are rapidly changing and subject to 
additional changes in the future. As further described 
in Item 3 – “Legal Proceedings,” we are also currently 
involved in various pieces of litigation in which the out-
come is uncertain. Compliance with these rapid chang-
es may substantially increase costs to our organization 
and could affect our future operating results.

Warrant Exercise 

DPL’s warrant holders could exercise their warrants 
to purchase 31.6 million shares of common stock at 
their discretion until March 12, 2012. As a result, DPL 
could be required to issue up to 31.6 million common 
shares in exchange for the receipt of the exercise price 
of $21.00 per share or pursuant to a cashless exercise 
process. The exercise of all warrants would have a 
dilutive effect on us and would increase the number of 
common shares outstanding and increase our common 
share of dividend costs, thus affecting any existing 
guidance on EPS and our cash flows.

Internal Controls 

Our internal controls, accounting policies and prac-
tices, and internal information systems are designed 
to enable us to capture and process transactions in a 
timely and accurate manner in compliance with 
generally accepted accounting principles (GAAP) in 
the United States of America, laws and regulations, 
taxation requirements and federal securities laws and 
regulations. We implemented corporate governance, 
internal control and accounting rules issued in connec-
tion with the Sarbanes-Oxley Act of 2002 (the “Act”). 
Our internal controls and policies 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 improprieties and undetected 
errors that could impact our results of operations, 
financial condition or cash flows.

Collective Bargaining Agreements

Approximately 54% of our employees are under a col-
lective bargaining agreement. During the third quarter 
of 2008, we will begin negotiation discussions with 
employees covered under our collective bargaining 

DPL Inc. 

21

 
agreement which is set to expire in November 2008. If 
the collective bargaining agreement expires before a 
new agreement is reached, we would attempt to per-
suade our employees to continue working while nego-
tiations continue. We believe that we maintain a satis-
factory relationship with our employees, however, it is 
possible that the expiration of the collective bargaining 
agreement could result in labor disruptions affecting 
some or all of our operations. We recognize the impact 
that any resulting labor stoppages could have on our 
customers and have begun contingency planning if 
the collective bargaining agreement expires before a 
new one is reached. A lengthy strike by our employees 
would have an adverse effect on our operations and 
financial condition. 

Cyber Security and Terrorism

Man-made problems such as computer viruses or ter-
rorism may disrupt our operations and harm our oper-
ating results. We operate in a highly regulated industry 
that requires the continued operation of sophisticated 
information technology systems and network infrastruc-
ture. Despite our implementation of security measures, 
all of our technology systems are vulnerable to dis-
ability or failures due to hacking, viruses, acts of war or 
terrorism, and other causes. If our technology systems 
were to fail and we were unable to recover in a timely 
way, we would be unable to fulfill critical business func-
tions, which could have a material adverse effect on 
our business, operating results, and financial condition. 
In addition, our generation plants, fuel storage facilities, 
transmission and distribution facilities may be targets 
of terrorist activities that could disrupt our ability to pro-
duce or distribute some portion of our energy products. 
Any such disruption could result in a material decrease 
in revenues and significant additional costs to repair 
and insure our assets, which could have a material 
adverse effect on our business, operating results, and 
financial condition. The continued threat of terrorism 
and heightened security and military 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 uncertain-
ties or otherwise materially harm our business, operat-
ing results, and financial condition.

Item 1b  Unresolved Staff Comments

None.

Item 2  Properties

Information relating to our properties is contained in 
Item 1 – Electric Operations and Fuel Supply and Note 
4 of Notes to Consolidated Financial Statements.

Substantially all property and plants 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 (Mortgage).

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 discussed below, and to comply with 
applicable laws and regulations will not exceed the 
amounts reflected in our consolidated financial state-
ments. As such, costs, if any, that may be incurred in 
excess of those amounts provided as of December 31, 
2007, cannot be reasonably determined.

Executive Litigation

On May 21, 2007, we settled the litigation with the 
three former executives in exchange for our payment of 
$25 million. As part of this settlement, the three former 
executives relinquished and dismissed all their claims 
including those related to certain deferred compensa-
tion, restricted stock units (RSUs), MVE, Inc. (discon-
tinued subsidiary of DPL) incentives, stock options, 
and legal fees. See Note 15 of Notes to Consolidated 
Financial Statements.

22  DPL Inc.

Insurance Recovery Claim

Environmental 

On April 18, 2007, DPL and Associated Electric & Gas 
Insurance Services (AEGIS) mediated and reached 
a settlement regarding an insurance claim filed with 
AEGIS on January 13, 2006 to recoup legal fees asso-
ciated with the three former executives in which AEGIS 
agreed to pay DPL $14.5 million for legal fees incurred 
by DPL and associated with this litigation. The settle-
ment agreement was signed and executed on April 
30, 2007 and the recovery was recorded by DPL as a 
reduction to the operation and maintenance expense. 
On May 16, 2007, DPL filed a similar claim with 
Energy Insurance Mutual (EIM), to recoup additional 
legal expenses associated with our litigation against 
the former executives. That claim is pending.

State Income Tax Audit

On February 13, 2006, we received correspondence 
from the Ohio Department of Taxation (ODT) notify-
ing us that ODT has 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 result in a balance 
due of $90.8 million before interest and penalties. We 
have reviewed the proposed audit adjustments and 
are vigorously contesting the ODT findings and notice 
of assessment through all administrative and judicial 
means available. On March 29, 2006, we filed peti-
tions for reassessment with the ODT to protest each 
assessment as well as request corrected assessments 
for each tax year. On October 12, 2006, we signed 
a Memorandum of Understanding with the ODT that 
stated if the ODT’s positions are ultimately sustained 
in judicial proceedings, the total additional tax liability 
that we would be subject to for tax years 2002 through 
2004 would be no more than $50.7 million before inter-
est as opposed to the $90.8 million stated in the ODT’s 
correspondence of February 13, 2006. We believe 
we have recorded adequate tax reserves related to 
the proposed adjustments; however, we cannot predict 
the outcome, which could be material to our results of 
operations and cash flows.

We are also under audit review by various state 
agencies for tax years 2002 through 2006. We have 
also filed an appeal to the Ohio Board of Tax Appeals 
for tax years 1998 through 2001. Depending upon the 
outcome of these audits and the appeal, we may be 
required to increase our tax provision if actual amounts 
ultimately determined exceed recorded reserves. We 
believe we have adequate reserves in each tax juris-
diction but cannot predict the outcome of these audits.

On April 2, 2007, the U.S. Supreme Court unani-
mously overturned the rulings of two lower courts and 
concluded that the CAA’s New Source Review (NSR) 
requirements are triggered when a major physical or 
operational change at a facility results in an increase in 
the facility’s annual emissions (Environmental Defense 
et al. v. Duke Energy Corp. et al.). The outcome of this 
case is significant to DP&L because it eliminates one 
of DP&L’s major arguments in the lawsuit filed against 
it by the Sierra Club. The Court decided that an annual 
rate of emissions could be used to determine if major 
modifications have been made to a plant as opposed 
to an hourly emission rate as Duke had argued. Using 
the annual rate makes it more likely that most plant 
modifications will be found to be “major” modifications, 
thus requiring EPA permits. DP&L can still defend 
against the allegations of NSR violations if it can 
establish that the activities at issue did not cause total 
annual emissions to increase or that the projects that 
resulted in increased emissions were undertaken for 
routine maintenance, repair, and replacement activities.
In September 2004, the Sierra Club filed a law-
suit against the Company and the other owners of the 
Stuart generating station in the United States District 
Court for the Southern District of Ohio for alleged viola-
tions of the CAA, including issues similar to those 
presented in the Duke Energy case and other issues 
relating to alleged violations of opacity limitations. 
DP&L, on behalf of all co-owners, is leading the 
defense of this matter. A sizable amount of discovery 
has taken place and expert reports were filed at vari-
ous times from May through September, 2007. On 
February 14, 2008, upon the request of the Sierra Club, 
DP&L and the other owners of the Stuart generating 
station, the Court approved another sixty day stay of 
proceedings to permit the parties the opportunity to 
determine if a settlement of the case could be reached. 
Settlement negotiations are ongoing.

Additional information relating to legal proceed-
ings involving DPL and DP&L is contained in Item 1 
– Environmental Considerations, Item 1 – Competition 
and Regulation, and Item 8 – Note 18 of Notes to 
Consolidated Financial Statements.

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 distribut-
ed 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. As of December 31, 2007, all earnings reinvest-
ed in the business of DP&L were available for DP&L 
common stock dividends. We expect all 2007 earnings 
reinvested in the business of DP&L to be available for 
DP&L common stock dividends, payable to DPL.

On February 1, 2007, our Board of Directors autho-
rized a 4% dividend increase on DPL’s common stock, 
raising the annual dividend on common shares from 

$1.00 per share to $1.04 per share. These dividends 
were paid in each quarter during 2007.

On December 13, 2007, our Board of Directors 
authorized a 6% dividend increase on DPL’s common 
stock, raising the annual dividend on common shares 
from $1.04 per share to $1.10 per share. These 
dividends will be paid in each quarter during 2008.

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 our equity compensation 
plans as of December 31, 2007 is disclosed in Item 
12 – Security Ownership of Certain Beneficial Owners 
and Management and Related Stockholder Matters, 
which incorporates such information by reference 
to our proxy statement for the 2008 Annual Meeting 
of Shareholders.

(a)  In 2003, we recorded a cumulative effect of an accounting change related to the adoption of SFAS 143 “Accounting for Asset Retirement 
Obligations”. In 2005, we recorded an additional obligation in response to FASB Interpretation Number (FIN) 47, “Accounting for Conditional 
Asset Retirement Obligations, an interpretation of FASB Statement No. 143.” See Item 7 – Management’s Discussion and Analysis of Financial 
Condition and Results of Operations.

(c)  During 2007, our rating agencies upgraded our corporate credit and debt ratings. 

(d)  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 May 2007, DPL 
settled the litigation with the 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.

Item 7  Management’s Discussion 
and Analysis of Financial Condition 
and Results of Operations 

This report includes the combined filing of DPL Inc. 
(DPL) and The Dayton Power and Light Company 
(DP&L). DP&L is the principal subsidiary of DPL pro-
viding approximately 99% of DPL’s total consolidated 
revenue and approximately 92% of DPL’s total con-
solidated 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. 

Certain statements contained in this discussion 
are “forward-looking statements” within the meaning 
of the Private Securities Litigation Reform Act of 1995. 
Matters discussed in this report that relate to events 
or developments that are expected to occur in the 
future, including management’s expectations, strategic 
objectives, business prospects, anticipated economic 
performance and financial condition and other 
similar matters constitute forward-looking statements. 
Forward-looking statements are based on manage-
ment’s beliefs, assumptions and expectations of 
future economic performance, taking into account the 
information currently available to management. These 
statements are not statements of historical fact and 
are typically identified by terms and phrases such as 
“anticipate,” “believe,” “intend,” “estimate,” “expect,” 
“continue,” “should,” “could,” “may,” “plan,” “project,” 
“predict,” “will” and similar expressions. Such forward-
looking statements are subject to risks and uncertain-
ties, and investors are cautioned that outcomes and 
results may vary materially from those projected due 
to various factors beyond our control, including but not 
limited to: abnormal or severe weather and catastroph-
ic weather-related damage; unusual maintenance 
or repair requirements; changes in fuel costs and pur-
chased power, coal, environmental emissions, natural 
gas and other commodity prices; volatility and changes 
in markets for electricity and other energy-related

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 efficient 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 through this manage-
ment. These risks include but are not limited to elec-
tricity wholesale price risk, fuel supply and price risk 
and power plant performance. 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 fuel source, 
cost structure and operating characteristics. We are 

DPL Inc. 

27

 
focused on the operating efficiency of these power 
plants and maintaining 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:

■ Governor’s Bill

On September 25, 2007, Senate Bill 221 was intro-
duced in the Ohio Legislature. The bill codifies, in draft 
form, the governor’s proposed energy policy. The bill 
was passed by the Senate on October 31, 2007. The 
Ohio House of Representatives has assigned the bill to 
committee and is taking testimony from interested 
parties. As the bill is not yet in final form, the outcome 
of this proceeding and its financial impact on 
the Company cannot be determined at this time.

■ Greenhouse Gases

The rules issued by the United States Environmental 
Protection Agency (USEPA) and Ohio Environmental 
Protection Agency (Ohio EPA) that require substantial 
reductions in sulfur dioxide (SO2), mercury and nitro-
gen oxides (NOx) emissions may impact our business 
and operations. We are installing (and have installed) 
emission control technology and are taking other 
measures to comply with required reductions.

In addition to the requirements related to emis-
sions of SO2, NOx and mercury noted above, there is 
a growing concern nationally and internationally about 
global climate change and the contribution of emis-
sions of greenhouse gases, including most significant-
ly, carbon dioxide (CO2). This concern has led 
to increased interest in legislation at the federal level 
and actions at the state level as well as litigation 

relating to greenhouse gas emissions, including a 
recent U.S. Supreme Court decision holding that the 
USEPA has the authority to regulate CO2 emissions 
from motor vehicles under the Clean Air Act (CAA). 
Increased pressure for carbon dioxide emissions 
reduction is also coming from investor organizations 
and the international community. If legislation or regula-
tions are passed at the federal or state levels imposing 
mandatory reductions of CO2 and other greenhouse 
gases on generation facilities, the cost to DPL and 
DP&L of such reductions could be material.

■ Fuel Prices

Recently, the coal market has experienced unprec-
edented price increases. To highlight the significance 
of this volatility, the coal settle price on the New York 
Mercantile Exchange (NYMEX) increased significantly 
during the first few weeks of 2008. We are now in 
a market for coal that clears on international, rather 
than solely domestic supply and consumption. Our 
domestic price is increasingly affected by international 
supply disruptions and demand balance. Exports from 
the U.S. have increased in recent years and most 
significantly during the last six months. In addition, 
domestic issues like government-imposed direct costs 
and permitting issues are affecting mining costs and 
supply availability. We have responded to increases in 
the price of coal by entering into contracts to hedge 
our exposure to fuel requirements and other energy-
related commodities. We may not be able to hedge the 
entire exposure of our operations from commodity price 
volatility. To the extent we are not able to hedge against 
price volatility, our results of operations, financial 
position or cash flows could be materially affected. 

2007 Financial Overview 

As more fully discussed in later sections of this 
MD&A, the following were the significant themes and 
events for 2007:

■ For the year ended December 31, 2007, DPL’s basic 
and diluted earnings per share (EPS) of $2.06 
and $1.88, respectively, increased over the basic and 
dilutive EPS for the same period in 2006 by $0.82 
and $0.73, respectively. 

■ DPL’s revenues increased 9% over 2006 primarily 
due to increases in weather driven retail sales volume, 

28  DPL Inc.

increases in average retail and wholesale rates and 
the revenue realized from the PJM capacity auctions. 
DPL’s fuel costs decreased 6% from 2006, while pur-
chased power costs and operation and maintenance 
expense increased over 2006. 

■ DP&L’s revenues increased 9% over 2006 primarily 
due to increases in weather driven retail sales volume, 
increases in average retail rates and the revenue 
realized from the PJM capacity auctions. DP&L’s 
fuel costs decreased 6% from 2006 while purchased 
power costs and operation and maintenance expense 
increased over 2006. 

■ On March 1, 2007, pursuant to the Company’s 
strategy of reducing its long-term debt, DPL redeemed 
the $225 million 8.25% Senior Notes when they 
became due.

■ On April 18, 2007, DPL and Associated Electric 
& Gas Insurance Services (AEGIS) mediated and 
reached a settlement regarding an insurance claim 
filed with AEGIS, on January 13, 2006, to recoup legal 
fees associated with the three former executives 
in which AEGIS agreed to pay DPL $14.5 million for 
legal fees incurred by DPL and associated with this 
litigation. The settlement agreement was signed and 
executed on April 30, 2007 and the recovery was 
recorded by DPL as a reduction to operation and 
maintenance expense. 

■ On April 25, 2007, DPLE completed the sale of its 
Darby and Greenville electric peaking generation facili-
ties, providing DPL with approximately $151 million 
in cash. Darby Station was sold to Columbus Southern 
Power (CSP), a utility subsidiary of American Electric 
Power (AEP), for approximately $102 million in cash. 
Greenville Station was sold to Buckeye Power, Inc. for 
approximately $49 million in cash. 

■ On May 21, 2007, we settled the litigation with the 
three former executives in exchange for our payment 
of $25 million. The $25 million settlement was funded 
from the sale of financial assets held in DP&L’s Master 
Trust deferred compensation. As a result of this 
settlement, DPL realized a net pretax gain in continu-
ing and discontinued operations of $31 million and 
$8.2 million, respectively. As part of this settlement, the 

three former executives relinquished and dismissed all 
their claims including those related to certain deferred 
compensation, restricted stock units (RSUs), MVE 
(discontinued subsidiary of DPL) incentives, stock 
options and legal fees. See Note 15 of Notes to 
Consolidated Financial Statements.

■ In July 2007, DPL completed a depreciation rate 
study for non-regulated generation property based 
on its property, plant and equipment balances as of 
December 31, 2005, with adjustments for subsequent 
scrubber additions. The results of the depreciation 
study concluded that depreciation rates should be 
reduced due to asset lives being extended beyond 
previously estimated lives. DPL adjusted the depre-
ciation rates for its non-regulated generation prop-
erty, effective August 1, 2007, reducing depreciation 
expense. For the year ended December 31, 2007, 
the reduction in depreciation expense increased 
income from continuing operations by $9.5 million, 
increased net income by approximately $6.0 million 
and increased basic EPS by approximately $0.06 
per share. See Note 1 of Notes to Consolidated 
Financial Statements.

■ On October 26, 2007, the Board of Directors 
approved a resolution permitting the transfer of 
925,000 shares of DPL Inc. 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 common stock with a fair 
value of $27.4 million to the Pension and resulting in 
fully funded status at December 31, 2007.

■ On November 15, 2007, the Ohio Air Quality 
Development Authority (OAQDA) issued $90 million of 
OAQDA Revenue Bonds 2007 Series A, due November 
2040. See Note 7 of Notes to Consolidated Financial 
Statements.

■ On February 1, 2007 and on December 13, 2007, 
our Board of Directors authorized dividend increases 
of approximately 4% and 6%, respectively, increasing 
our dividend per share from $1.00 per share to $1.10 
per share. The 4% increase to dividends, were paid 
in each quarter during 2007. The 6% increase to divi-
dends will be paid each quarter in 2008.

Results of Operations – DPL Inc. 

DPL’s results of operations include the results of its 
subsidiaries, including the consolidated results of its 
principal subsidiary DP&L and all of DP&L’s consoli-
dated subsidiaries. DP&L provides approximately 99% 
of the total revenues of DPL. All material intercompany 
accounts and transactions have been eliminated in 
consolidation. A separate specific discussion of the 
results of operations for DP&L is presented elsewhere 
in this report.

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 generation facilities not being utilized to meet its 
retail demand.

DPL Inc. – Revenues 

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 will 
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. 

For the year ended December 31, 2007, revenues 
increased $122.2 million, or 9%, to $1,515.7 from 
$1,393.5 for the same period in the prior year. This 
increase was primarily the result of higher average 
rates for retail and wholesale sales, higher retail sales 
volume and an increase in RTOs ancillary revenue. 
Retail revenues increased $74.8 million, resulting from 
a 3% increase in weather driven sales volume as total 
degree days increased 9%, and a 3% increase in aver-
age retail rates primarily relating to the environmental 
investment and storm recovery riders. These increases 
resulted in a $38.4 million rate variance and a $34.1 
million sales volume variance. Wholesale revenue 
increased $6.2 million primarily resulting from a 12% 
increase in wholesale average rates, partially offset 
by an 8% decrease in sales volume. This resulted in a 
favorable $19.8 million wholesale price variance and 
an unfavorable $13.6 million volume variance. RTO 
ancillary and other revenues, consisting primarily of 
compensation for use of DP&L’s transmission assets, 
regulation services, reactive supply and operating 
reserves and capacity payments under the RPM con-
struct, increased $41.2 million over the same period 
in 2006. This increase primarily resulted from $30.9

million realized from the PJM capacity auction, $8.7 
million of PJM transmission losses and congestion 
credits and $2.3 million from the sale of financial trans-
mission rights (FTRs). RTO ancillary revenues from the 
PJM capacity auction are substantially offset by RTO 
ancillary charges for PJM capacity charges included 
in purchased power. Other RTO ancillary revenues are 
partially offset by other RTO ancillary charges in pur-
chased power.

For the year ended December 31, 2006, revenues 

increased $108.6 million, or 8%, to $1,393.5 from 
$1,284.9 for the same period in the prior year. This 
increase was primarily the result of higher average 
retail rates and higher wholesale sales volume, partially 
offset by lower retail sales volume and lower average 
rates for wholesale revenues. Retail revenues increased 
$64.8 million primarily resulting from an increase in 
average rates related to the Rate Stabilization Plan 
surcharge and other regulated asset recovery riders 
resulting in a $93.0 million price variance, partially 
offset by lower retail sales volume resulting in a $29.4 
million volume variance. Sales volume declined 3% in 
2006 from 2005 due to milder weather which resulted 
in lower heating and cooling degree days. Heating 
degree days declined 11% and cooling degree days 
declined 20%. Wholesale revenue increased $40.8 mil-
lion primarily related to a 34% increase in sales volume 
resulting in a $45.8 million volume variance, partially 
offset by a decrease in wholesale average rates result-
ing in a $5.0 million price variance. For 2006, the RTO 
ancillary revenues increased $2.8 million, or 4%, to 
$77.2 million from $74.4 million in 2005. 

DPL Inc. – Margins, Fuel and Purchased Power 

For 2007, gross margin of $900.3 million increased 
$14.9 million, or 2%, from $885.4 million in 2006. As a 
percentage of total revenues, gross margin decreased 
to 59.4% in 2007 compared to 63.5% in 2006. This 
result primarily reflects the favorable impact of both 
retail and wholesale revenues discussed above and 
lower fuel costs offset by increased purchased power 
costs. Fuel costs, which include coal, gas, oil and 
emission allowance costs, decreased by $20.9 mil-
lion, or 6%, in 2007 compared to the same period in 
2006 primarily due to lower generation output of 4% 
resulting from scheduled and unscheduled plant out-
ages, as well as a 2% decrease in average fuel prices. 
Purchased power increased $128.2 million in 2007 
compared to the same period in 2006 resulting from a 
$57.6 million increase in charges relating to higher pur-
chased power volume and a $41.2 million increase due 
to higher average market rates. Also included in pur-
chased power is a $28.4 million increase related large-

ly to RTO ancillary charges for PJM capacity charges. 
The increase in purchased power volume was primarily 
the result of increased retail sales volume and partner 
operated generating facilities being less available com-
pared to the prior year due to planned and unplanned 
outages. In addition, we purchase power when market 
prices are below the marginal costs associated with 
our higher cost generating facilities. The RTO ancillary 
charges for PJM capacity charges are substantially off-
set by RTO ancillary revenues for PJM capacity result-
ing in minimal impact to gross margin.

For 2006, gross margin of $885.4 million increased 

$70.7 million, or 9%, from $814.7 million in 2005. As a 
percentage of total revenues, gross margin remained 
flat in 2006 at 63.5% compared to 63.4% in 2005. This 
result reflects the favorable impact of the rate stabiliza-
tion plan on revenues offsetting the increasing fuel and 
purchase power costs. In prior years, rising fuel and 
purchase power costs had eroded gross margin. Fuel 
costs, which include coal, gas, oil and emission allow-
ance costs, increased by $12.2 million, or 4%, in 2006 
compared to the same period in 2005 primarily due 
to increased fuel prices. Purchased power increased 
$25.7 million, or 19%, in 2006 compared to the same 
period in 2005 primarily resulting from increased 
charges of $30.8 million relating to higher purchased 
power volume and an increase of $0.9 million in RTO 
ancillary costs. These increases were partially offset 
by lower average market rates reducing purchased 
power costs by $6.0 million. The increase in purchased 
power volume resulted from our decision to purchase 
power at lower average market rates instead of running 
our higher cost generating facilities. In addition, from 
time to time, we purchased power when our generating 
facilities were not available due to scheduled mainte-
nance and forced outages.

DPL Inc. – Impairment of Peaking Stations 

In 2006, DPL recorded a $71.0 million impairment 
charge relating to the sale of the Greenville and Darby 
Stations’ peaking generation facilities. There was 
no impairment charge in 2007. See Note 5 of Notes to 
Consolidated Financial Statements.

DPL Inc. – Depreciation and Amortization

For 2007, depreciation and amortization expense 
decreased $17.0 million from 2006, primarily reflecting 
the absence of depreciation for the peaking units sold 
in April 2007 which reduced the expense by $10.0 
million and the impact of lower depreciation rates 
for generation property which were put into effect on 
August 1, 2007, reducing the expense by $9.5 million. 
This decrease was partially offset by a $2.4 million 
increase to the expense related to increased plant 
balances primarily resulting from the installation of 
pollution control equipment.

For 2006, depreciation and amortization expense 

increased $4.5 million from 2005 relating to completed 
projects in both the distribution and production areas 
increasing our overall plant base.

DPL Inc. – Amortization of Regulatory Assets 

For 2006, operation and maintenance expense 
increased $46.4 million, or 21%, compared to 2005 
primarily resulting from a $13.5 million increase in legal 
fees primarily related to the litigation with former execu-
tives; $5.5 million increase in PJM administrative fees, 
which include $2.5 million deferred in 2005 by Public 
Utilities Commission of Ohio (PUCO) authority (rate 
relief was granted in February 2006); a $5.1 million 
increase in the low-income assistance program costs; 
$4.1 million of coal brokering credits received in 2005 
that were not received in 2006; a $3.7 million increase 
related to lump sum bonus and retirement payments 
to former executives (not related to our litigation with 
the three former executives); a $3.1 million increase in 
operating and maintenance expenses, which related to 
removal costs and peaker engine repairs; a $2.7 
million increase in line clearance expenses; a $2.6 
million increase in mark-to-market adjustments and 
forfeitures of RSUs; $2.1 million in long-term incentive 
compensation relating to performance and restricted 
shares and a $1.0 million increase in pension and 
benefits expenses. These increases were partially 

For 2007, amortization of regulatory assets increased 
$3.2 million to $10.8 million from $7.6 million in 
2006, primarily reflecting the amortization of incremen-
tal 2004/2005 severe storm costs that began on 
August 1, 2006.

For 2006, amortization of regulatory assets 

increased $5.6 million to $7.6 million compared to the 
same period in 2005. The increase in amortization of 
regulatory assets reflects $2.6 million for the amortiza-
tion of costs incurred to accommodate unbundled rates 
and electric choice bills in the customer billing system; 
$1.3 million for the amortization of PJM administrative 
fees deferred for the period October 2004 through 
January 2006 and $1.2 million for the amortization of 
incremental 2004/2005 severe storm costs.

DPL Inc. – Investment Income 

For 2007, investment income of $11.3 million 
decreased $6.5 million from $17.8 million for the same 
period in 2006. This decrease was primarily the result 
of lower interest income relating to lower cash and 
short-term investment balances in 2007 compared to 
2006. This decrease was partially offset by $3.2 million

former executives.

For 2006, investment income of $17.8 million 

decreased $33.1 million from $50.9 million for the same 
period in 2005. This decrease was primarily the result 
of a $23.4 million decrease in gains on public and 
income investments realized in 2005, a $4.6 million 
decrease in foreign currency translation gains realized 
in 2005 for the liquidation of investments denominated 
in Euros and a $4.8 million decrease in interest 
income resulting from lower cash balances in 2006 
compared to 2005.

DPL Inc. – Net Gain on Settlement of 
Executive Litigation

On May 21, 2007, we settled the litigation with the 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 (previously owned 
subsidiary of DPL) incentives, stock options and legal 
fees. As a result of this settlement, during the second 
quarter ended June 30, 2007, DPL realized a net pre-
tax gain in continuing operations of approximately 
$31.0 million. See Note 15 of Notes to Consolidated 
Financial Statements.

DPL Inc. – Interest Expense 

For 2007, interest expense decreased $21.2 million, 
or 21%, compared to the same period in 2006 primar-
ily as a result of $15.5 million less interest associated 
with the redemption of DPL debt ($225 million, 8.25% 
Senior Notes) and $9.1 million of greater capitalized 
interest primarily related to increased pollution control 
capital expenditures. These decreases were partially 
offset by $3.4 million of interest expense associated 
with DP&L’s new $100 million, 4.8% Series pollution 
control bonds issued September 13, 2006.

For 2006, interest expense decreased $35.5 mil-

lion, or 26%, compared to the same period in 2005 
resulting from the debt reduction that occurred in 2005 
and a higher capitalized interest of $10.9 million in 
2006 compared to 2005 associated with our major con-
struction projects.

DPL Inc. – Charge for Early Redemption of Debt 

In 2005, DPL recorded $61.2 million in charges result-
ing from premiums paid for the early redemption of 
debt, including write-offs of unamortized debt expense 
and debt discounts. These charges did not recur in 
2006 or 2007.

DPL Inc. – Other Income (Deductions) 

For 2007, other income of $2.9 million increased $4.1 
million from other deductions of $1.2 million recorded 
for the same period of the prior year. The increase 
primarily resulted from the recognition of a $2.1 million 
deferred credit related to a litigation settlement (which 
was not part of the executive litigation settlement).

For 2006, other income (deductions) was $14.7 
million less than the same period in 2005 primarily due 
to gains of $12.3 million realized in 2005 from the 
sale of pollution control emission allowances. There 
were no sales of pollution control emission allowances 
during 2006. 

DPL Inc. – Income Tax Expense 

For 2007, income taxes from continuing operations 
increased $52.7 million, or 76%, compared to 2006 due 
to an increase in pre-tax book income, a decrease in 
the effective tax rate primarily reflecting the phase-out 
of the Ohio Franchise Tax and adjustments recorded in 
2006 to true-up book tax expense to the tax return. 

For 2006, income taxes from continuing operations 

decreased $10.1 million, or 13%, compared to 2005 
due to a decrease in pre-tax book income, a decrease 
in the effective tax rate primarily reflecting the phase-
out of the Ohio Franchise Tax and adjustments record-
ed in 2005 and 2006 to true-up book tax expense to 
the tax return.

On June 30, 2005, Governor Taft signed House 
Bill 66 into law which significantly changed the tax 
structure in Ohio. The major provisions of the bill 
included phasing-out the Ohio Franchise Tax, phasing-
out the Ohio Personal Property Tax for non-utility tax-
payers and phasing-in a Commercial Activities Tax. The 
Ohio Franchise Tax phase-out required second quarter 
2005 adjustments to income tax expense. Income 
taxes from continuing operations were increased by 
$1.4 million in 2007 and reduced by $1.5 million in 
2006 while income taxes from discontinued operations 
were increased by $1.3 million in 2006 as a result of 
the tax law change. Other applicable provisions of 
House Bill 66 have been reflected in Note 8 of Notes to 
Consolidated Financial Statements.

DPL Inc. – Cumulative Effect of Accounting Change, 
Net of Tax 

In 2005, the cumulative effect of an accounting 
change resulted in a charge of $3.2 million related to 
the adoption of the provisions of FASB Interpretation 
No. 47, “Accounting for Conditional Asset Retirement 
Obligations an interpretation of FASB Statement No. 
143” (FIN 47). See Note 1 of Notes to Consolidated 
Financial Statements.

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 will 
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 whole-
sale 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.

For the year ended December 31, 2007, revenues 
increased $122.2 million, or 9%, to $1,507.4 million 
from $1,385.2 million for the same period in the prior 
year. This increase was primarily the result of higher 
average rates for retail and wholesale sales, higher 
retail sales volume and an increase in RTO ancillary 
revenue. These increases were partially offset by lower 
wholesale sales volume. Retail revenues increased 
$59.3 million, primarily as result of a 3% increase in 
weather driven sales volume as total degree days 
increased 9%, and a 3% increase in the average retail 
rates primarily relating to the environmental investment 
and storm recovery riders. These increases resulted 
in a $31.2 million sales volume variance and a $25.8 
million rate variance. Wholesale revenue increased 
$21.8 million primarily resulting from a 15% increase 
in wholesale average rates, partially offset by an 8% 
decrease in sales volume. This resulted in a favorable 
$46.2 million wholesale price variance and an unfa-
vorable $24.4 million volume variance. RTO ancillary 
revenues, consisting primarily of compensation for use 
of DP&L’s transmission assets, regulation services, 
reactive supply and operating reserves and capacity 
payments under the RPM construct, increased $41.1 
million over the same period in 2006. This increase 
primarily resulted from $30.9 million realized from the 
PJM capacity auction, $8.7 million of PJM transmission 
losses and congestion credits and $2.3 million from 
the sale of financial transmission rights (FTRs). RTO 
ancillary revenues from the PJM capacity auction are 
substantially offset by RTO ancillary charges for PJM 
capacity charges included in purchased power. Other 

34  DPL Inc.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
RTO ancillary revenues are partially offset by other 
RTO ancillary charges in purchased power.

For 2006, revenues increased 8% to $1,385.2 mil-

lion compared to $1,276.9 million in 2005, reflecting an 
increase of $108.3 million. This increase was primar-
ily the result of higher average rates for retail sales, 
greater wholesale sales volume and increased ancil-
lary revenues associated with participation in a RTO. 
These increases were partially offset by lower retail 
sales volume and lower average rates for wholesale 
sales. Retail revenues increased $53.2 million, primarily 
resulting from a $78.3 million increase relating to higher 
average rates and increased miscellaneous revenues 
of $0.9 million, partially offset by decreased sales 
volume of $26.0 million resulting from milder weather 
experienced in 2006 compared to 2005. The higher 
average rates were primarily the result of the rate sta-
bilization plan surcharge, and regulated asset recov-
ery riders implemented throughout 2006. Wholesale 
revenues increased $52.3 million, primarily related 
to an $88.6 million increase in sales volume, partially 
offset by a $36.3 million decrease in average market 
rates. During 2006, RTO ancillary revenues increased 
$2.8 million to $77.2 million from $74.4 million in 2005. 
Heating degree-days were down 11% to 5,076 in 
2006 compared to 5,702 in 2005. In addition, cooling 
degree-days were down 20% to 855 in 2006 compared 
to 1,075 in 2005.

DP&L – Margins, Fuel and Purchased Power 

For 2007, gross margin of $891.7 million increased 
$13.6 million, or 1.5%, from $878.1 million in 2006. As a 
percentage of total revenues, gross margin decreased 
to 59.2% in 2007 compared to 63.4% in 2006. This 
result primarily reflects the favorable impact of both 
retail and wholesale revenues discussed above and 
lower fuel costs offset by increased purchased power 
costs. Fuel costs, which include coal, gas, oil and 
emission allowance costs, decreased by $19.8 mil-
lion, or 6%, in 2007 compared to the same period in 
2006 primarily due to lower generation output of 4% 
resulting from scheduled and unscheduled plant out-
ages, as well as a 2% decrease in average fuel prices. 
Purchased power increased $128.4 million in 2007 
compared to the same period in 2006. The increase 
in purchased power primarily results from a $57.6 mil-
lion increase relating to higher volumes of purchased 
power, a $41.2 million increase due to higher average 
market rates and $28.4 million related to RTO ancil-
lary charges for PJM capacity charges. The increase 

in purchased power volume was primarily the result 
of increased retail sales volume and partner operated 
generating facilities being less available compared to 
the prior year due to planned and unplanned outages. 
In addition, we purchase power when market prices 
are below the marginal costs associated with our high-
er cost generating facilities. The RTO ancillary charges 
for PJM capacity charges are substantially offset by 
RTO ancillary revenues for PJM capacity resulting in 
minimal impact to gross margin. 

For 2006, gross margin increased $66.2 million to 

$878.1 million from $811.9 million in 2005. As a per-
centage of total revenues, gross margin remained rela-
tively flat in 2006 at 63.4% compared to 63.6% in 2005. 
This result reflects the favorable impact of the rate 
stabilization plan on revenues offsetting the increas-
ing fuel and purchased power costs. In prior years, 
rising fuel and purchased power costs had eroded 
gross margin. Fuel costs, which include coal, gas, oil 
and emission allowance costs, increased by $17.3 mil-
lion, or 5%, in 2006 as a result of higher market prices. 
Purchased power costs increased by $24.8 million, or 
17%, in 2006 compared to 2005 primarily resulting from 
higher volumes of power purchased. The increase in 
purchased power volume resulted from our decision to 
purchase power at lower average market rates instead 
of running our higher cost generating facilities. In 
addition, from time to time, we had to purchase power 
to source power sales when our generating facilities 
were not available due to scheduled maintenance and 
forced outages.

compared to 2006. This variance was primarily the 
result of increased boiler maintenance costs of $17.7 
million, a $9.4 million increase related to operating 
expenses for the generating facilities, a $3.5 million 
increase related to turbine maintenance costs, and a 
$3.0 million increase in overhead line and substation

For 2006, operation and maintenance expense 
increased $33.4 million, or 17%, compared to 2005 
primarily resulting from a $5.6 million increase in the 
Low-Income Assistance Program costs; $5.5 million in 
PJM administrative fees, including $2.5 million deferred 
in 2005 by PUCO authority (rate relief was granted in 
February 2006); $4.1 million of coal brokering credits 
received in 2005 that were not received in 2006; $3.7 
million of lump sum bonus and retirement payments 
for former executives (not related to our litigation with 
the three former executives); a $3.1 million increase in 
operating and maintenance expenses which related 
to removal costs and peaker engine repairs; $2.7 mil-
lion related to line clearance; $1.9 million increase in 
long-term incentive costs; a $1.9 million increase in 
reserves for insurance, injuries and damages; a $0.9 
million increase in pension and benefits expenses; and 
a $0.9 million increase in mark-to-market adjustments 
and forfeitures of RSUs. These increases were partially 
offset by a $1.2 million decrease in Directors’ and 
Officers’ liability insurance premiums and a $1.1 million 
decrease in Sarbanes-Oxley compliance fees.

DP&L – Depreciation and Amortization 

For 2007, depreciation and amortization expense 
decreased $5.5 million from 2006, primarily reflecting 
the impact of lower depreciation rates for generation 
property which were put into effect on August 1, 2007, 
reducing the expense by $9.5 million. This decrease 

was partially offset by an increase to the expense relat-
ed to increased plant balances primarily resulting from 
the installation of pollution control equipment.

Depreciation and amortization increased $6.1 
million in 2006 compared to 2005 primarily reflecting a 
higher plant base.

DP&L – Amortization of Regulatory Assets 

For 2007, amortization of regulatory assets increased 
$3.2 million to $10.8 million from $7.6 million in 2006, 
primarily reflecting the amortization of incremental 
2004/2005 severe storm costs that began on August 1, 
2006. 

For 2006, amortization of regulatory assets 

increased $5.6 million to $7.6 million compared to the 
same period in 2005. The increase in amortization of 
regulatory assets reflects $2.6 million for the amortiza-
tion of costs incurred to accommodate unbundled rates 
and electric choice bills in the customer billing system; 
$1.3 million for the amortization of PJM administrative 
fees deferred for the period October 2004 through 
January 2006 and $1.2 million for the amortization of 
incremental 2004/2005 severe storm costs.

DP&L – Investment Income

For 2007, investment income increased $17.0 million 
to $23.7 million from $6.7 million for the same period 
in 2006. This increase was primarily the result of a 
realized gain of $14.8 million on the transfer of DPL 
common stock to the DP&L Retirement Income Plan 
Trust (Pension) and $3.2 million in realized gains 
from the sale of financial assets held in DP&L’s Master 
Trust Plan for deferred compensation used for the 
settlement payment to the three former executives. 

DP&L – Net Gain on Settlement of Executive Litigation

On May 21, 2007, we settled the litigation with the 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 the second quarter ended June 30, 2007, DP&L 
realized a net pre-tax gain in continuing operations 
of $35.3 million. See Note 15 of Notes to Consolidated 
Financial Statements.

DP&L – Interest Expense 

For 2007, interest expense decreased $1.1 million, or 
5%, compared to 2006 primarily as a result of $9.1 
million of greater capitalized interest primarily related to 
increased pollution control capital expenditures. These 

36  DPL Inc.

 
 
 
 
 
decreases were partially offset by $3.4 million of inter-
est expense associated with DP&L’s new $100 million, 
4.8% Series pollution control bonds issued September 
13, 2006 and $2.8 million in interest on a short-term 
loan from DPL.

Interest expense decreased $14.7 million, or 39%, 

in 2006 compared to 2005, primarily relating to $10.9 
million of increased capitalized interest resulting from 
higher pollution control capital expenditures at the 
generating plants and $5.3 million of lower interest 
expense reflecting the refinancing of pollution control 
bonds at reduced interest rates in 2005, lower debt 
service charges associated with DPL’s early retire-
ment of ESOP debt, and the elimination of the interest 
penalty resulting from the delayed exchange offer of 
the $470 million 5.125% Series First Mortgage Bonds. 
These decreases were slightly offset by $1.4 million 
of interest expense associated with DP&L’s new $100 
million 4.8% Series pollution control bonds issued 
September 13, 2006.

DP&L – Charge for Early Redemption of Debt 

In 2005, DP&L recorded $4.1 million in charges result-
ing from premiums paid for the early redemption of 
debt, including write-offs of unamortized debt expense 
and debt discounts. These charges did not recur in 
2006 or 2007.

DP&L – Other Income (Deductions)

For 2007, other income of $2.9 million increased $4.1 
million from the other deductions of $1.2 million record-
ed for the same period of the prior year. The increase 
primarily resulted from the recognition of a $2.1 million 
deferred credit related to a litigation settlement (which 
was not part of the executive litigation settlement).

For 2006, other income (deductions) decreased 
$7.8 million compared to the same period in 2005. This 
decrease is primarily attributable to $12.3 million in 
gains recognized on the sale of pollution control emis-
sion allowances during 2005, partially offset by $7.0 
million in reduced investment management fees.

DP&L – Income Tax Expense 

For 2007, income taxes from continuing operations 
increased $0.9 million compared to 2006 due to an 
increase in pre-tax book income, a decrease in the 
effective tax rate primarily reflecting the phase-out of 
the Ohio Franchise Tax and adjustments recorded in 
2006 to true-up book tax expense to the tax return. 
For 2006, income tax expense increased $4.1 
million compared to the same period in 2005 primarily 

resulting from higher income.

On June 30, 2005, Governor Taft signed House 
Bill 66 into law which significantly changed the tax 
structure in Ohio. The major provisions of the bill 
include phasing-out the Ohio Franchise Tax, phasing-
out the Personal Property Tax for non-utility taxpayers 
and phasing-in a Commercial Activities Tax. As a result 
of House Bill 66, income taxes were reduced by $0.7 
million and $1.6 million, in 2007 and 2006, respectively. 
Other applicable provisions of House Bill 66 have been 
reflected in the consolidated financial statements.

DP&L – Cumulative Effect of Accounting Change, 
Net of Tax 

In 2005, the cumulative effect of an accounting 
change resulted in a charge of $3.2 million related to 
the adoption of the provisions of FASB Interpretation 
No. 47, “Accounting for Conditional Asset Retirement 
Obligations an interpretation of FASB Statement No. 
143” (FIN 47). See Note 1 of Notes to Consolidated 
Financial Statements.

Financial Condition, Liquidity and 
Capital Requirements

DPL’s financial condition, liquidity and capital require-
ments, includes the consolidated results of its principal 
subsidiary DP&L and all of DP&L’s consolidated 
subsidiaries. All material intercompany accounts and 
transactions have been eliminated in consolidation. 
During the fourth quarter of 2007 we identified 

immaterial changes in certain accounts payable 
balances that had not been correctly presented in 
our prior period cash flow statements. Changes in 
accounts payable balances representing capital 
expenditures had previously been classified with cash 
flows from operating activities and should have been 
classified with capital expenditures as part of investing 
activities. Accordingly, the Consolidated Statements of 
Cash Flows for all periods presented have been reclas-
sified to conform to the current presentation.

On July 27, 2005, DPL’s Board authorized the 
repurchase of up to $400 million of common stock 
from time to time in the open market or through private 
transactions. DPL completed this share repurchase 
program through a series of open market purchases 
on August 21, 2006. This resulted in 14.9 million shares 
being repurchased at an average price of $26.91 per 
share and at a total cost of $400 million. These shares 
are currently held as treasury shares at DPL. No shares 
were repurchased during 2007.

DPL’s Cash provided by Operating Activities

DPL’s cash and cash equivalents totaled $134.9 million 
at December 31, 2007, compared to $262.2 million at 
December 31, 2006, a decrease of $127.3 million. The 
decrease in cash and cash equivalents was primar-
ily attributed to $346.2 million in capital expenditures, 
$225.0 million used to retire long-term debt and $111.7 
million in dividends paid on common stock, partially 
offset by $318.1 million in cash generated from operat-
ing activities, $158.4 million proceeds from the sale of 
the peakers and aircraft and $63.2 million restricted 
fund draws to fund pollution control capital expendi-
tures. At December 31, 2007, DPL had $37.0 million 
restricted funds held in trust relating to the issuance of 
$90.0 million pollution control bonds. These funds will 
be used to fund pollution control capital expenditures.

DP&L’s Cash Position 

DP&L’s cash and cash equivalents totaled $13.3 mil-
lion at December 31, 2007, compared to $46.1 million 
at December 31, 2006, a decrease of $32.8 million. 
The decrease in cash and cash equivalents was pri-
marily attributed to $343.2 million in capital expendi-
tures and $125.0 million in dividends paid on common 
stock to the parent, partially offset by $353.0 million in 
cash generated from operating activities and $63.2 mil-
lion restricted fund draws to fund pollution control capi-
tal expenditures. At December 31, 2007, DP&L had 
$37.0 million restricted funds held in trust relating to the 
issuance of the $90.0 million pollution control bonds. 
These funds will be used to fund the pollution control 
capital expenditures.

$ 353.0  $  343.8  $  356.3

The tariff-based revenue from our energy business 
continues to be the principal source of cash from 
operating activities. Management believes that the 
diversified retail customer mix of residential, commer-
cial, and industrial classes coupled with the rate relief 
approved by the PUCO for 2006 and beyond provides 
us with a reasonably predictable gross cash flow 
from operations.

DPL generated net cash from operating activities of 
$318.1 million, $286.8 million and $303.6 million in 
2007, 2006, and 2005, respectively. The net cash pro-
vided by operating activities for 2007, 2006, and 2005 
was primarily the result of cash received from utility 
customers, partially offset by cash used for fuel, pur-
chased power, operating expenditures, interest, and 
taxes. The year-to-year fluctuations in working capital 
results from the timing of payments made and cash 
receipts from our utility customers.

DP&L’s Cash provided by Operating Activities

DP&L generated net cash from operating activities 
of $353.0 million, $343.8 million and $356.3 million 
in 2007, 2006 and 2005, respectively. The net cash 
provided by operating activities for 2007, 2006 and 
2005 was primarily the result of cash received from 
utility customers, partially offset by cash used for fuel, 
purchased power, operating expenditures, interest and 
taxes. The year-to-year fluctuations in working capital 
results from the timing of payments made and cash 
receipts from our utility customers.

respectively, compared to DPL’s net cash flows pro-
vided by investing activities of $700.1 million in 2005. 
Net cash flows used for investing activities in 2007 
were related to capital expenditures, partially offset by 
the sale of peakers and aircraft. Net cash flows used 
for investing activities in 2006 were related to capital 
expenditures and the purchases of short-term invest-
ments and securities, partially offset by the sale of 
short-term investments and securities. Net cash flows 
provided by investing activities for 2005 were related 
to the proceeds from the sale of the private equity 
securities which are classified as discontinued opera-

tions and the sale of short-term investments and public 
securities unrelated to discontinued operations, 
partially offset by capital expenditures and purchases 
of short-term investments and securities.

DP&L’s Cash used for Investing Activities

DP&L’s net cash flows used for investing activities 
were $343.2 million, $332.9 million and $167.9 million 
in 2007, 2006 and 2005, respectively. Net cash flows 
used for investing activities for 2007, 2006 and 2005 
were due to capital expenditures. 

Financing Activities

For the years ended December 31, 2007, 2006 
and 2005, cash flows from financing activities were 
as follows:

DPL’s Cash used for Financing Activities

DPL’s net cash flows used for financing activities were 
$257.6 million, $412.8 million and $610.0 million in 
2007, 2006 and 2005, respectively. Net cash flows 
used for financing activities in 2007 were the result of 
cash used to redeem the $225.0 million 8.25% Senior 
Notes on March 1, 2007 and to pay dividends to com-
mon stockholders of $111.7 million. These uses of cash 
were partially offset by $63.2 million of withdrawals 
from the trust set up as a result of issuing the pollution 
control bonds. Net cash flows used for financing activi-
ties in 2006 were the result of cash used to repurchase 
$400.0 million of common stock and pay dividends to 
common stockholders of $112.4 million. These uses 
of cash were partially offset by $89.9 million of with-
drawals from the trust set up as a result of issuing the 
pollution control bonds. Net cash flows used for financ-
ing activities for 2005 were primarily the result of cash 
used to retire $462.6 million of long-term debt, pay pre-
miums on the early redemption of debt of $54.7 million 
and pay dividends to common stockholders of $115.3 
million. These uses of cash were partially offset by 
cash received relating to the exercise of stock options 
of $22.7 million.

On February 1, 2007, our Board of Directors 
announced that it had raised the quarterly dividend 
to $0.26 per share payable March 1, 2007 to com-
mon shareholders of record on February 14, 2007. 

This increase results in an annualized dividend rate of 
$1.04 per share, or a 4% increase that was paid during 
2007. On December 13, 2007 our Board of Directors 
announced that it had raised the quarterly dividend 
to $0.275 per share effective with the next dividend 
declaration date. This increase results in an annualized 
dividend rate of $1.10 per share, or a 6% increase that 
will be paid during 2008.

DP&L’s Cash used for Financing Activities

DP&L’s net cash flows used for financing activities 
were $42.7 million, $11.0 million and $159.4 million 
in 2007, 2006 and 2005, respectively. Net cash flows 
used for financing activities for 2007 were the result 
of cash used to pay common stock dividends to DPL 
of $125.0 million, partially offset by $63.2 million of 
withdrawals from the trust set up as a result of issuing 
the pollution control bonds and net cash received from 
the issuance of short-term debt. Net cash flows used 
for financing activities for 2006 were the result of cash 
used to pay common stock dividends to DPL of $100.0 
million, partially offset by $89.9 million of withdrawals 
from the trust set up as a result of issuing the pollution 
control bonds. Net cash flows used for financing activi-
ties for 2005 were primarily the result of cash used to 
retire $218.9 million of long-term debt and pay com-
mon stock dividends to DPL of $150.0 million. These 
uses of cash were partially offset by the net cash 
received from the issuance of long-term debt.

DPL and DP&L have obligations to make future 
payments for capital expenditures, debt agreements, 
lease agreements and other long-term purchase obli-
gations, and have certain contingent commitments 
such as guarantees. We believe our cash flows from 
operations, the credit facilities (existing or future 
arrangements), the senior notes, and other short- and 
long-term debt financing will be sufficient to satisfy our 
future working capital, capital expenditures, and other 
financing requirements for the foreseeable future. Our 
ability to generate positive cash flows is dependent on 
general economic conditions, competitive pressures, 
and other business and risk factors described in Item 
1a of this Form 10-K. If we are unable to generate suf-
ficient cash flows or otherwise comply with the terms 
of our credit facilities and the senior notes, we may 
be required to refinance all or a portion of our existing 
debt or seek additional financing alternatives. A 
discussion of each of our critical liquidity commitments 
is outlined below.

DPL’s construction additions were $347 million, $352 
million and $180 million in 2007, 2006 and 2005, 
respectively, and are expected to approximate $205 
million in 2008. Planned construction additions for 2008 
relate to DP&L’s environmental compliance program, 
power plant equipment, and its transmission and 
distribution system.

DP&L’s construction additions were $344 million, 
$349 million and $178 million in 2007, 2006 and 2005, 
respectively, and are expected to approximate $203 
million in 2008. Planned construction additions for 2008 
relate to DP&L’s environmental compliance program, 
power plant equipment, and its transmission and 
distribution system.

Capital projects are subject to continuing review 

and are revised in light of changes in financial and 
economic conditions, load forecasts, legislative and 
regulatory developments and changing environmental 
standards, among other factors. Over the next three 
years, DPL, through its subsidiary DP&L, is projecting 
to spend an estimated $490 million in capital projects. 
Our ability to complete capital projects and the reli-
ability of future service will be affected by our financial 
condition, the availability of internal funds and the rea-
sonable cost of external funds. We expect to finance 
our construction additions in 2008 with a combination 
of cash on hand, short-term financing, tax-exempt 
debt and cash flows from operations.

Debt and Debt Covenants 

On March 25, 2004, DPL completed a $175 million 
private placement of unsecured 8% Series Senior 
Notes due March 2009. The purchasers were granted 
registration rights in connection with the private place-
ment under an Exchange and Registration Rights 
Agreement. Pursuant to this agreement, DPL was 
obligated to file an exchange offer registration state-
ment by July 22, 2004, have the registration statement 
declared effective by September 20, 2004 and 
consummate the exchange offer by October 20, 2004. 
DPL failed (1) to have a registration statement 
declared effective and (2) to complete the exchange 
offer according to this timeline. As a result, DPL 
had been accruing additional interest at a rate of 
0.5% per year for each of these two violations, up to 

an additional interest rate not to exceed in the aggre-
gate 1.0% per year. As each violation was cured, the 
additional interest rate decreased by 0.5% per annum. 
DPL’s exchange offer registration statement for these 
securities was declared effective by the SEC on June 
27, 2006. As a result, on June 27, 2006, DPL ceased 
accruing 0.5% of the additional interest. On July 31, 
2006, DPL ceased accruing the other 0.5% of addi-
tional interest when the exchange of registered notes 
for the unregistered notes was completed.

During the first quarter 2006, the Ohio Department 

of Development (ODOD) awarded DP&L the ability to 
issue, over the next three years, up to $200 million of 
qualified tax-exempt financing from the ODOD’s 2005 
volume cap carryforward. The financing is to be used 
to partially fund the ongoing flue gas desulfurization 
capital projects. The PUCO approved DP&L’s applica-
tion for this additional financing on July 26, 2006.
On September 13, 2006, the Ohio Air Quality 
Development Authority (OAQDA) issued $100 million 
of 4.80% fixed interest rate OAQDA Revenue bonds 
2006 Series A due September 1, 2036. In turn, DP&L 
borrowed these funds from the OAQDA. The payment 
of principal and interest on the bonds when due is 
insured by an insurance policy issued by Financial 
Guaranty Insurance Company. DP&L is using the 
proceeds from these borrowings to assist in financing 
its portion of the costs of acquiring, constructing 
and installing certain solid waste disposal and air 
quality facilities at Miami Fort, Killen and Stuart gener-
ating stations. 

On November 15, 2007, the Ohio Air Quality 
Development Authority issued $90 million of collater-
alized, variable rate OAQDA Revenue bonds, 2007 
Series A due November 1, 2040. In turn, DP&L bor-
rowed these funds from the OAQDA. The payment 
of principal and interest on the bonds when due is 
insured by an insurance policy issued by Financial 
Guaranty Insurance Company. On January 30, 2008, 
FGIC’s credit rating was downgraded by Fitch Ratings 
from ‘AAA’ to ‘AA’ and remains on negative ratings 
watch. On January 31, 2008, FGIC’s credit rating was 
downgraded by Standard & Poor’s from ‘AAA’ to ‘AA’ 
and placed on credit watch. On February 14, 2008, 
FGIC’s credit rating was downgraded by Moody’s from 

40  DPL Inc.

 
‘Aaa to A3.’ These downgrades, as well as the recent downgrades or pending downgrades of other major bond 
insurers, could result in DP&L’s variable rate bonds having substantially higher interest rate in succeeding auctions 
and increase the risk that these bonds may have a failed auction. The maximum interest rate is capped at 12%. 
Management will continue to evaluate the current market conditions. If these conditions do not improve, we may 
redeem our variable rate bonds and issue fixed rate bonds. We have sufficient liquidity to redeem the variable rate 
bonds using cash on hand or through funds available to us by our revolving credit line until fixed rate bonds 
are issued. DP&L is using the proceeds from these borrowings to assist in financing its portion of the costs of 
acquiring, constructing and installing certain solid waste disposal and air quality facilities at Miami Fort, Killen, 
Stuart and Conesville generating stations. These facilities are currently under construction and the proceeds from 
the borrowing have been placed in escrow with the trustee (the Bank of New York) and are being drawn upon 
only as facilities are built and qualified costs are incurred. In the event any of the proceeds are not drawn, DP&L 
would eventually be required to return the unused proceeds to bondholders. DP&L expects to draw down the 
remaining available funds from this borrowing over the next two years. 

On November 21, 2006, DP&L entered into a new $220 million unsecured revolving credit agreement replac-
ing its $100 million facility. This new agreement has a five year term that expires on November 21, 2011 and that 
provides DP&L with the ability to increase the size of the facility by an additional $50 million at any time. The facil-
ity contains one financial covenant: DP&L’s total debt to total capitalization ratio is not to exceed 0.65 to 1.00. This 
covenant is currently met. DP&L had no outstanding borrowings under this credit facility at December 31, 2007. 
Fees associated with this credit facility are approximately $0.2 million per year. Changes in credit ratings, however, 
may affect fees and the applicable interest. This revolving credit agreement also contains a $50 million letter 
of credit sub-limit. DP&L has certain contractual 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. As of December 31, 2007, DP&L had no outstanding letters of credit against the facility.
On February 24, 2005, DP&L entered into an amendment to extend the term of its Master Letter of Credit 
Agreement with a financial lending institution for one year and to reduce the maximum dollar volume of letters of credit 
to $10 million. On February 17, 2006, DP&L renewed its $10 million agreement for one year. This agreement sup-
ports performance assurance needs in the ordinary course of business. This agreement was not renewed in 2007. 

Issuance of additional amounts of first mortgage bonds by DP&L is limited by the provisions of its mortgage; 

however, management believes that DP&L continues to have sufficient capacity to issue first mortgage bonds 
to satisfy its requirements in connection with its current refinancing and construction programs. The amounts and 
timing of future financings will depend upon market and other conditions, rate increases, levels of sales and 
construction plans.

During the second quarter ended June 30, 2007, DPL entered into a short-term loan to DP&L for $105 million. 
DP&L paid down $15 million of this loan during the third quarter ended September 30, 2007, and an additional $70 
million during the fourth quarter ended December 31, 2007, leaving a current outstanding balance of $20 million. 
This short-term loan does not affect our debt covenants. There are no other inter-company debt collateralizations 
or debt guarantees between DPL, DP&L and their subsidiaries. None of the debt obligations of DPL or DP&L are 
guaranteed or secured by affiliates and no cross-collateralization exists between any subsidiaries.

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

DPL Inc.

Such agreements fall outside the scope of FASB Interpretation No. 45, “Guarantor’s Accounting and Disclosure 
Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others.”

At December 31, 2007, DPL had $33.3 million of guarantees to third parties for future financial or 

performance assurance under such agreements, on behalf of DPLE. The guarantee arrangements entered into 
by DPL with these third parties cover all present and future obligations of DPLE 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 $0.5 million at December 31, 2007.

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:

We believe it is unlikely that either DPL or DP&L would be required to perform or incur any losses 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. As of December 31, 2007, DP&L 
could be responsible for the repayment of 4.9%, or $36.5 million, of a $745 million debt obligation that matures in 2026. 

Other than the guarantees discussed above, DPL and DP&L do not have any other off-balance sheet 

arrangements that have or are reasonably likely to have a current or future material effect on results of operations, 
financial condition, or cash flows.

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, 2007, these include:

Long-term debt: 
DPL’s long-term debt as of December 31, 2007, con-
sists of DP&L’s first mortgage bonds, tax-exempt pollu-
tion control bonds, DPL unsecured notes and includes 
current maturities and unamortized debt discounts.

DP&L’s long-term debt as of December 31, 2007, 
consists of first mortgage bonds, tax-exempt pollution 
control bonds and includes an unamortized debt 
discount. During 2007, DP&L entered into $90.0 million 
of long-term tax-exempt pollution control bonds due 
in 2040.

See Note 7 of Notes to Consolidated Financial 

Statements.

Interest payments: 
Interest payments associated with the long-term 
debt described above.

Pension and postretirement payments: 
As of December 31, 2007, 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 2017. 

Capital leases:
As of December 31, 2007, DPL, through its principal 
subsidiary, DP&L, had one capital lease that expires 
in September 2010.

Operating leases: 
As of December 31, 2007, DPL, through its principal 
subsidiary, DP&L, had several 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 portions of its coal requirements for its gener-
ating plants. 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 for its generating facilities. 

Reserve for uncertain tax positions:
On January 1, 2007, we adopted Financial Accounting 
Standards Board (FASB) Interpretation No. 48, 
“Accounting for Uncertainty in Income Taxes” (FIN 48). 
As of December 31, 2007, our total reserve for uncer-
tain tax positions is $65.3 million including interest 
($42.5 million net of federal tax benefit). See Note 1 of 
Notes to Consolidated Financial Statements. 

Other contractual obligations: 
As of December 31, 2007, DPL and DP&L had various 
other contractual obligations including non-cancelable 
contracts to purchase goods and services with various 
terms and expiration dates.

We enter into various commercial commitments, which 
may affect the liquidity of our operations. At December 
31, 2007, these include: 

Credit facilities:
In November 2006, DP&L replaced its previous $100 
million revolving credit agreement with a $220 million 
five year facility that expires on November 21, 2011. 
At December 31, 2007, there were no borrowings 
outstanding under this credit agreement. DP&L has 
the ability to increase the size of the facility by an 
additional $50 million at any time.

Market Risk

During the conduct of our business, we are subject 
to certain market risks including, but not limited to, 
changes in commodity prices for electricity, coal, envi-
ronmental emissions and gas, and fluctuations in inter-
est rates. Commodity pricing exposure includes the 
impacts of weather, market demand, increased com-
petition, and other economic conditions. For purposes 
of potential risk analysis, we use sensitivity analysis to 
quantify potential impacts of market rate changes on 
the results of operations. The sensitivity analysis 
represents hypothetical changes in market values that 
may or may not occur in the future. 

Our Risk Management Committee (RMC) is respon-
sible for establishing risk management policies and the 
monitoring and reporting of risk exposures. The RMC 
meets on a regular basis with the objective of identify-
ing, assessing, and quantifying material risk issues and 
developing strategies to manage these risks.

Commodity Pricing Risk 

Recently, the coal market has experienced unprec-
edented price increases. To highlight the significance 
of this volatility, the coal settle price on the New York 
Mercantile Exchange (NYMEX) increased significantly 
during the first few weeks of 2008. We are now in 
a market for coal that clears on international, rather 
than solely domestic supply and consumption. Our 
domestic price is increasingly affected by international 
supply disruptions and demand balance. Exports from 
the U.S. have increased in recent years and most 
significantly during the last six months. In addition, 
domestic issues like government-imposed direct costs 
and permitting issues are affecting mining costs and 
supply availability. We have responded to increases in

the price of coal by entering into contracts to hedge 
our exposure to fuel requirements and other energy-
related commodities. We may not be able to hedge the 
entire exposure of our operations from commodity price 
volatility. To the extent we are not able to hedge against 
price volatility, our results of operations, financial posi-
tion or cash flows could be materially affected.

Approximately 12% of DPL’s and 22% of DP&L’s 

2007 electric revenues were from sales of excess 
energy and capacity in the wholesale market. Energy 
and capacity in excess of the needs of existing retail 
customers are sold in the wholesale market when we 
can identify opportunities with positive margins. As 
of December 31, 2007, a hypothetical increase or 
decrease of 10% in DPL’s annual wholesale revenues 
could result in approximately an $11 million increase 
or decrease to net income, assuming no increases 
in fuel and purchased power costs. As of December 
31, 2007, a hypothetical increase or decrease of 10% 
in DP&L’s annual wholesale revenues could result in 
approximately a $22 million increase or decrease to net 
income, assuming no increases in fuel and purchased 
power costs.

DPL’s fuel (including coal, gas, oil and emission 

allowances) and purchased power costs as a percent 
of total operating costs in 2007 and 2006 were 54% 
and 46%, respectively. DP&L’s fuel (including coal, 
gas, oil and emission allowances) and purchased 
power costs as a percent of total operating costs in 
2007 and 2006 were 54% and 52%, respectively. We 
have substantially all of the total expected coal volume 
needed to meet our retail and firm wholesale sales 
requirements for 2008 under contract. The majority of 
our contracted coal is purchased at fixed prices. Some 
contracts provide for periodic adjustment and some 
are priced based on market indices. Substantially all 
contracts have features that limit price escalations in 
any given year. Our consumption of SO2 allowances 
should decline in 2008 due to planned emission control 
upgrades. We do not expect to purchase SO2 allow-
ances for 2008. The exact consumption of SO2 allow-
ances will depend on market prices for power, avail-
ability of our generation units, the timing of emission 
control equipment upgrade completion, and the actual 
sulfur content of the coal burned. DP&L does not plan 
to purchase NOx allowances for 2008. 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. Based on higher volume and price, 
fuel costs are forecasted to be 15% to 25% higher in 
2008 compared to 2007. 

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 production costs. As of December 
31, 2007, a hypothetical increase or decrease of 10% 
in DPL’s annual fuel and purchased power costs could 
result in approximately a $34 million increase 
or decrease to net income. As of December 31, 2007, 
a hypothetical increase or decrease of 10% in DP&L’s 
annual fuel and purchased power costs could result 
in approximately a $35 million increase or decrease to 
net income.

Interest Rate Risk

As a result of our normal investing and borrowing 
activities, our financial results are exposed to fluctua-
tions 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. 
The Company has both fixed and variable rate long-
term debt; our variable rate debt is comprised of 
publicly held secured notes. The variable rate bonds 
bear interest based on a prevailing rate determined via 
auction and which is applicable during each 35 day 
auction period. The auction rate is, among other fac-
tors, driven by market demand, supply, market interest 
rates and other economic conditions. 

DP&L’s variable rate bonds were issued with bond 

insurance, a credit enhancement feature that enabled 
these bonds to be issued with a ‘AAA’ credit rating. 
Bond insurance for DP&L’s bonds was provided by 
the Financial Guaranty Insurance Company (FGIC). On 
January 30, 2008, FGIC’s credit rating was downgrad-
ed by Fitch Ratings from ‘AAA’ to ‘AA’ and remains on 
negative ratings watch. On January 31, 2008, FGIC’s 
credit rating was downgraded by Standard & Poor’s 
from ‘AAA’ to ‘AA’ and placed on credit watch. On 
February 14, 2008, FGIC’s credit rating was downgrad-
ed by Moody’s from ‘Aaa to A3.’ These downgrades, 
as well as the recent downgrades or pending down-
grades of other major bond insurers, could result in 
DP&L’s variable rate bonds having substantially higher 
interest rate in succeeding auctions and increase the 
risk that these bonds may have a failed auction. The 
maximum interest rate is capped at 12%. Management 
will continue to evaluate the current market conditions. 
If these conditions do not improve, we may redeem 
our variable rate bonds and issue fixed rate bonds. 
We have sufficient liquidity to redeem the variable rate 
bonds using cash on hand or through funds available 
to us by our revolving credit line until fixed rate 
bonds are issued.

Critical Accounting Estimates 

DPL’s and DP&L’s consolidated financial statements 
are prepared in accordance with US GAAP. In connec-
tion with the preparation of these financial statements, 
our management is required to make assumptions, esti-
mates and judgments that affect the reported amounts 
of assets, liabilities, revenues, expenses and the relat-
ed disclosure of contingent liabilities. These assump-
tions, estimates and judgments are based on our his-
torical experience and assumptions 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 
differed materially from actual results. Significant items 
subject to such judgments include: the carrying value 
of property, plant and equipment; unbilled revenues; 
income taxes; valuation of regulatory assets and 
liabilities; the valuation of insurance and claims costs; 
the valuation of assets and liabilities related to employ-
ee benefits; and the valuation of contingent and 
other obligations.

Impairments and Assets Held for Sale:  In accordance 
with Statement of Financial Accounting Standards No. 
144 “Accounting for the Impairment or Disposal of 
Long-Lived Assets” (SFAS 144), long-lived assets to 
be held and used are reviewed for impairment when-
ever events or circumstances indicate that the carry-
ing 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 recover-
ability using future cash flows, we make projections 
based on a number of assumptions and estimates of 
growth rates, future economic conditions, 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 recoverable from its undis-
counted cash flows. The measurement of impairment 
loss is the difference between the carrying amount 
and fair value of the asset. Long-lived assets to be 
disposed of and/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 utili-
ties. At the end of each month, unbilled revenues are 
determined by the estimation of unbilled energy provid-
ed to customers since the date of the last meter read-
ing, projected line losses, the assignment of unbilled 
energy 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 
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. Effective January 1, 2007, we adopt-
ed Financial Accounting Standards Board Interpretation 
No. 48 (FIN 48), Accounting for Uncertainty in Income 
Taxes. Taking into consideration the uncertainty and 
judgment involved in the determination and filing of 
income taxes, FIN 48 establishes standards for rec-
ognition and measurement, in financial statements, of 
positions taken, or expected to be taken, by an entity in 
its income tax returns. Positions taken by an entity in its 
income tax returns that are recognized in the financial 
statements must satisfy a more-likely-than-not recogni-
tion threshold, assuming that the position will 
be examined by taxing authorities with full knowledge 
of all relevant information. 

Deferred income tax assets and liabilities are pro-
vided, representing future effects on income taxes for 
temporary differences 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 forecast-
ed taxable income or successfully implement tax 
planning strategies may affect the realization of 
deferred tax assets.

Regulatory Assets and Liabilities:  Application of FASB 
Statement of Financial Accounting Standards No. 
71, “Accounting for the Effects of Certain Types of 
Regulation” (SFAS 71) requires us to reflect the effect 
of rate regulation in our Financial Statements. For regu-
lated 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 

46  DPL Inc.

customer refunds through future rates and when 
revenue is collected from customers for expenditures 
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 regula-
tory 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 historical experience, as 
well as discussions with applicable regulatory authori-
ties. If recovery of a regulatory asset is determined to 
be less than probable, it will be written off in the period 
such assessment is made. We currently believe the 
recovery of our regulatory assets is probable. See Note 
3 of our Consolidated Financial Statements.

Asset Retirement Obligations:  In accordance with 
FASB Statement of Financial Accounting Standards 
No.143, “Accounting for Asset Retirement Obligations” 
(SFAS 143) and FASB Interpretation No. 47 (FIN No. 
47), “Accounting for Conditional Asset Retirement 
Obligations, an interpretation of FASB Statement No. 
143,” 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. 
SFAS 143 also requires that components of previously 
recorded depreciation related to the cost of removal 
of assets upon retirement, whether legal asset retire-
ment obligations or not, must be removed from a com-
pany’s accumulated depreciation reserve. We make 
assumptions, estimates, and judgments that affect 
the reported amounts of assets, liabilities, and expens-
es as they relate to asset retirement obligations. These 
assumptions and estimates are based on historical 
experience and assumptions that we believe to be 
reasonable at the time. 

Insurance and Claims Costs:  In addition to insurance 
provided through third-party providers, our wholly-
owned captive subsidiary (MVIC) provides insur-
ance coverage solely to us and to our subsidiaries. 
Insurance and Claims Costs on the consolidated bal-
ance sheets includes insurance reserves of approxi-
mately $20.0 million and $22.0 million for 2007 and 
2006, respectively, based on actuarial methods and 
loss experience data. Such reserves are actuarially 

determined, in the aggregate, based on a reasonable 
estimation of insured events occurring. There is uncer-
tainty associated with the 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. 

Pension and Postretirement Benefits:  We account 
and disclose pension and postretirement benefits 
in accordance with the provisions of Statement of 
Financial Accounting Standards No. 158, “Employers’ 
Accounting for Defined Benefit Pensions and other 
Postretirement Plans, an amendment to FASB 
Statements 87, 88, 106 and 132R.” This Standard 
requires the use of assumptions, 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. 

In 2008, we are maintaining our long-term rate of 
return assumptions of 8.50% for pension and 6.00% 
for other postretirement benefits assets that reflect the 
effect of recent trends on our long-term view. We are 
also maintaining our assumed discount rate of 5.75% 
for pension and postretirement benefits expense 
to reflect current interest rate conditions. Changes in 
other components used in the determination of pension 
and postretirement benefits costs will result in 
a decrease of pension costs of $2.5 million, excluding 
any special adjustments required under SFAS 88. 
We do not anticipate any special adjustments to 
expense in 2008.

In future periods, differences in the actual return on 

pension plan assets and assumed return, or changes 
in the discount rate, will affect the timing of contribu-
tions to the pension plan, if any. We provide postretire-
ment healthcare benefits to employees who retired 
prior to 1987. A one percentage point change in the 
assumed healthcare trend rate would affect postretire-
ment 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 generally accepted accounting principles. In 
recording such reserves, we may make assumptions, 

DPL Inc.

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 to be reasonable at the time.

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 99% of DPL’s total consolidated 
revenue and approximately 92% of DPL’s total con-
solidated 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.

DPL’s results of operations, financial position and 

cash flows, includes the consolidated results of its sub-
sidiaries, including its principal subsidiary DP&L and 
all of its consolidated subsidiaries. All material inter-
company accounts and transactions have been elimi-
nated in consolidation. 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 information presented is segregated 
by registrant.

1  Summary of Significant Accounting 
Policies and Overview

Description of Business 

DPL is a diversified regional energy company orga-
nized in 1985 under the laws of Ohio. DPL’s principal 
subsidiary is The Dayton Power and Light Company 
(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 515,000 retail custom-
ers. DP&L also purchases retail peak load require-
ments from DPL Energy LLC (DPLE, one of DPL’s 
wholly-owned subsidiaries). 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. 

DPL’s significant subsidiaries (all of which are 

wholly-owned) include DPLE, which engages in the 
operation of peaking generating facilities; DPL Energy 
Resources, Inc. (DPLER), which sells retail electric 
energy under contract to major industrial and commer-
cial customers in West Central Ohio; and Miami 
Valley Insurance Company (MVIC), our captive insur-
ance company that provides insurance sources to 

us and our subsidiaries. DP&L has one significant 
subsidiary, DPL Finance Company, Inc., which is 
wholly-owned and provides financing to DPL, DP&L 
and other affiliated companies.

DPL and DP&L conduct their principal business 

in one business segment – Electric.

Basis of Consolidation 

We prepare consolidated financial statements in accor-
dance with generally accepted accounting principles 
(GAAP) in the United States of America. The consoli-
dated financial statements include the accounts of 
DPL and DP&L and their majority-owned subsidiaries. 
Investments that are not majority owned are accounted 
for using the equity method when our investment allows 
us the ability to exert significant influence, as defined 
by GAAP. Undivided interests in jointly-owned genera-
tion facilities are consolidated on a pro rata basis. 
All material intercompany accounts and transactions 
are eliminated in consolidation. 

Estimates and Judgments 

The preparation of financial statements in conformity 
with GAAP requires us to make estimates and judg-
ments that affect the reported amounts of assets and 
liabilities, the disclosure of contingent assets and liabili-
ties at the date of the financial statements and the rev-
enue and expenses of the period reported. We record 
liabilities for probable estimated losses in accordance 
with Statement of Financial Accounting Standards 
No. 5 (SFAS 5), “Accounting for Contingencies.” To the 
extent a probable loss can only be estimated by 
reference to a range of equally probable outcomes and 
no amount within the range appears to be a better 
estimate than any other amount, we accrue for the low 
end of the range. Because of uncertainties related to 
these matters, accruals are based on the best informa-
tion available at the time. We evaluate the potential 
liability related to probable losses quarterly and may 
revise our estimates. Judgments and uncertain-
ties affecting the application of these estimates may 
result in materially different amounts being reported 
under different conditions or circumstances that may 
affect our financial position and results of operations. 
Significant items subject to such estimates and judg-
ments include: the carrying value of property, plant and 
equipment; unbilled revenues; the valuation of deriva-
tive instruments; the valuation of insurance and claims 
costs; the valuation allowances for receivables and 
deferred income taxes; regulatory assets and liabilities; 
reserves recorded for income tax exposures; litigation; 
contingencies and assets and liabilities related 
to employee benefits.

Reclassifications 

During the fourth quarter of 2007 we identified imma-
terial changes in certain accounts payable balances 
that had not been correctly presented in our prior 
period cash flow statements. Changes in accounts 
payable balances representing capital expenditures 
had previously been classified with cash flows from 
operating activities and should have been classified 
with capital expenditures as part of investing activi-
ties. Accordingly, the Consolidated Statements of Cash 
Flows for all periods presented have been reclassified 
to conform to the current presentation. As a result of 
these reclassifications, cash provided by operating 
activities for DPL decreased by $21.9 million from 
$308.7 million to $286.8 million and $10.5 million from 
$314.1 million to $303.6 million for the years ended 
December 31, 2006 and 2005, respectively. This same 
adjustment also decreased cash used for capital 
expenditures from investing activities to $335.6 million 
from $357.5 million in 2006 and to $169.6 million from 
$180.1 million in 2005. Cash provided by operating 
activities for DP&L decreased by $21.9 million from 
$365.7 million to $343.8 million and $10.5 million from 
$366.8 million to $356.3 million for the years ended 
December 31, 2006 and 2005, respectively. This same 
adjustment also decreased cash used for capital 
expenditures from investing activities to $332.9 million 
from $354.8 million in 2006 and to $167.9 million from 
$178.4 million in 2005. The reclassifications did not 
impact operating income or net income, working capi-
tal, any earnings per share measures or net change in 
cash and cash equivalents as previously reported. 

Revenues 

We record revenue for services provided but not yet 
billed to more closely match revenues with expenses. 
Accounts receivable on DPL’s consolidated balance 
sheets include unbilled revenue of $68.4 million and 
$68.7 million in 2007 and 2006, respectively. Accounts 
receivable on DP&L’s consolidated balance sheets 
include unbilled revenue of $60.5 million and $61.0 
million in 2007 and 2006, respectively. Also included in 
revenues are amounts charged to customers through 
a surcharge for recovery of uncollected amounts from 
certain eligible low-income households. These charges 
for both DPL and DP&L were $13.1 million for 2007, 
$11.9 million for 2006, and $6.2 million for 2005.

Accounts Receivable 

Our accounts receivable includes utility customer 
receivables, amounts due from our partners for jointly-
owned property, wholesale and subsidiary customer 
receivables, and electric unbilled revenue. We also 

include miscellaneous accounts receivables such as 
refundable franchise taxes. The amount is presented 
net of a provision for uncollectible accounts in 
the accompanying consolidated balance sheets.

Allowance for Uncollectible Accounts 

We establish provisions for uncollectible accounts 
using both historical average credit loss percentages 
of accounts receivable balances to project future 
losses and specific provisions for known credit issues.

Property, Plant and Equipment 

We record our ownership share of our undivided 
interest in jointly-held plants as an asset in property, 
plant and equipment. Property, plant and equipment 
are stated at cost. For regulated property, cost includes 
direct labor and material, allocable overhead costs 
and an allowance for funds used during construction 
(AFUDC). AFUDC represents the cost of borrowed 
funds and equity used to finance regulated construc-
tion projects. Capitalization of AFUDC ceases at 
either project completion or as of the date specified 
by regulators. AFUDC capitalized in 2007, 2006, and 
2005 was not material. 

For unregulated property, cost includes direct 
labor, material and overhead costs and interest capi-
talized during construction using FASB Statement of 
Accounting Standard No. 34, “Capitalization of Interest 
Cost.” Capitalized interest was $21.8 million in 2007, 
$12.9 million in 2006 and $2.6 million in 2005. 

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.

Depreciation 

Depreciation expense is calculated using the straight-
line method, which depreciates the cost of property 
over its estimated useful life. For DPL’s generation, 
transmission, and distribution assets, straight-line 
depreciation is applied on an average annual compos-
ite basis using group rates that approximated 2.9% in 
2007, 3.3% in 2006 and 3.3% in 2005. In July 2007, 
DPL completed a depreciation rate study for non-reg-
ulated generation property based on its property, plant 
and equipment balances during 2007. The results of 
the depreciation study concluded that DPL’s deprecia-
tion rates should be reduced due to asset lives beyond 
previously established lives. DPL adjusted the depre-
ciation rates for its non-regulated generation property, 
effective August 1, 2007. For the period from August 1, 

58  DPL Inc.

2007 to December 31, 2007, the reduction in depreciation expense increased income from continuing operations 
by approximately $9.5 million, increased net income by approximately $6.0 million, and increased basic EPS 
by approximately $0.06 per share. DPL’s depreciation expense was $134.8 million in 2007, $151.8 million in 2006, 
and $147.3 million in 2005.

(a)  During 2006, DPL entered into agreements to sell 630 MW of its peaking capacity relating to the Darby and Greenville stations of which 
$283.5 million of the assets presented in this table were held for sale at December 31, 2006. Disposition of these facilities occurred during 2007.

For DP&L’s generation, transmission, and distribution assets, straight-line depreciation is applied on an aver-
age annual composite basis using group rates that approximated 2.8% in 2007, 3.2% in 2006, and 3.2% in 2005. 
DP&L’s depreciation expense was $124.5 million in 2007, $130.0 million in 2006, and $123.9 million in 2005.

Asset Retirement Obligations 
We adopted the provisions of the Financial Accounting 
Standards Board (FASB) Statement of Financial 
Accounting Standards No. 143, “Accounting for Asset 

Retirement Obligations” (SFAS 143) during 2003. SFAS 
143 requires legal obligations associated with the 
retirement 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 
capitalized as part of the related long-lived asset and 
depreciated over the useful life of the related asset. 
SFAS 143 also requires that components of previously 
recorded depreciation related to the cost of removal of 
assets upon retirement, whether legal asset retirement 
obligations or not, be removed from a company’s accu-
mulated depreciation reserve. Our legal obligations 
associated with the retirement of our long-lived assets 
under SFAS 143 consisted primarily of river intake and 
discharge structures, coal unloading facilities, loading 
docks, ice breakers and ash disposal facilities. 

In March of 2005, the FASB issued FASB 
Interpretation No. 47, “Accounting for Conditional 
Asset Retirement Obligations, an interpretation of FASB 
Statement No. 143 (FIN No. 47).” We implemented FIN 
No. 47 in the fourth quarter of 2005 effective January 1, 
2005 for certain asset retirement obligations, primarily 
the removal of asbestos, at some of our generation sta-
tions. Application of FIN No. 47 resulted in an increase 
in our net property, plant and equipment of $1.8 million 
and an increase in our asset retirement obligation of 
$7.2 million. The difference of $5.3 million represents 
the before tax ($3.2 million after tax) cumulative effect 
of the adoption of FIN No. 47, as of January 1, 2005. 
The before tax impact on 2005 net income was $0.9 
million ($0.5 million after tax) which consisted of $0.6 
million of accretion expense and $0.3 million deprecia-
tion expense.

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.

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 
asset retirement obligations associated with these 
assets. We have recorded $91.5 million and $86.2 mil-
lion in estimated costs of removal at December 31, 
2007 and 2006, respectively, as regulatory liabilities 
for our transmission and distribution property. These 

amounts represent the excess of the cumulative remov-
al costs recorded through depreciation rates versus the 
cumulative removal expenditures actually incurred. See 
Note 3 of Notes to Consolidated Financial Statements.

Regulatory Accounting 
We apply the provisions of FASB Statement of Financial 
Accounting Standards No. 71, (SFAS 71) “Accounting 
for the Effects of Certain Types of Regulation,” to 
the transmission and distribution portion of our busi-
ness. In accordance with SFAS 71, regulatory assets 
and liabilities are recorded in the consolidated balance 
sheets. 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. If we were required to 
terminate application of SFAS 71 for all of our regulated 
operations, we would have to record the amounts of 
all regulatory assets and liabilities in the Consolidated 
Statement of Results of Operations at that time. See 
Note 3 of Notes to Consolidated Financial Statements.

Inventory 

Inventories, carried at average cost, include coal, 
limestone, oil and gas used for electric generation, 
and materials and supplies for utility operations. We 
account for our emission allowances as inventory, and 
record emission allowance inventory at weighted aver-
age 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 aver-
age cost of emission allowances used each quarter. 
In June 2007, we successfully completed the 
installation of flue gas desulfurization (FGD) equipment 
at our Killen Station and are in the process of installing 
similar equipment at the J.M. Stuart Station and part-
ner-owned facilities. The installation of the FGD equip-
ment is expected to significantly reduce our future 
emissions resulting in emission allowance inventory in 
excess of our needs. Accordingly, in fourth quarter 

60  DPL Inc.

 
 
 
 
 
of 2007 we began planning for and managing our 
excess allowances as part of our operations and will 
record the net gains or losses from sales of these 
excess allowances as income from continuing opera-
tions rather than reporting these transactions as non-
operating income. There were no transactions recorded 
during the fourth quarter under the new policy. 
Prior to this, emission allowances were peripheral to 
the management of the business and the net gains 
or losses from their sale were accounted for in other 
income (deductions).

Repairs and Maintenance 

Costs associated with all planned work and mainte-
nance 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 either capitalized or expensed based on 
defined units of property as required by the Federal 
Energy Regulatory Commission (FERC).

Income Taxes 

We apply the provisions of FASB Statement of 
Financial Accounting Standards No. 109, “Accounting 
for Income Taxes” (SFAS 109). SFAS 109 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 Taxes in the 
consolidated balance sheets. Deferred tax assets 
are recognized for deductible temporary differences. 
Valuation reserves are provided 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 
liabilities are recorded to recognize that the income 
taxes will be recoverable / refundable through 
future revenues. 

We file a consolidated U.S. federal income tax 

return in conjunction with our subsidiaries. The 
consolidated tax liability is allocated to each subsidiary 
as specified in our tax allocation agreement which 
provides a consistent, systematic and rational 
approach. See Note 8 of Notes to Consolidated 
Financial Statements.

Accounting for Uncertainty in Income Taxes 

On January 1, 2007, we adopted FASB Interpretation 
No. 48, “Accounting for Uncertainty in Income Taxes” 
(FIN 48). There was no material impact to our overall 
results of operations, cash flows or financial position. A 
reconciliation of the beginning and ending amount of 
unrecognized tax benefit is as follows:

(0.8)
 –

Balance as of December 31, 2007 

$  56.3

None of the amount of unrecognized tax benefits is 
due to uncertainty in the timing of deductibility.

We recognize interest and penalties related to 
unrecognized tax benefits in income taxes. During 
2007, we recognized $4.1 million in interest related to 
unrecognized tax benefits. As of December 31, 2007, 
$9.0 million in interest has been accrued. No penalties 
have been accrued as of December 31, 2007.

Taxes for calendar years 2004 through 2006 

remain open to examination by the jurisdictions in 
which we are subject to taxation. None of the unrec-
ognized tax benefits are expected to significantly 
increase or decrease within the next twelve months.

Accounting for Taxes Collected from Customers 
and Remitted to Governmental Authorities

In January 2007, we adopted Emerging Issues Task 
Force (EITF) No. 6-03 “How Taxes Collected from 
Customers and Remitted to Governmental Authorities 
Should Be Presented in the Income Statement” (EITF 
No. 6-03). EITF No. 6-03 requires a registrant to dis-
close how taxes collected from customers are pre-
sented in the financial statements, i.e., gross or net. 
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 record-
ed as revenues in the accompanying Consolidated 
Statements of Results of Operations for the twelve 
months ended December 31, 2007, December 31, 
2006 and December 31, 2005 as follows:

Stock-Based Compensation 

In December 2004, the FASB issued Statement of 
Financial Accounting Standard No. 123 (revised 2004), 
“Share-Based Payment” (SFAS 123R). SFAS 123R 
replaces SFAS 123, “Accounting for Stock-Based 
Compensation,” and supersedes Accounting Principles 
Board (APB) Opinion No. 25 (Opinion 25), “Accounting 
for Stock Issued to Employees.” SFAS 123R requires 
a public entity to measure the cost of employee ser-
vices received and paid with equity instruments to be 
based on the fair-value of such equity on the grant 
date. This cost is recognized in results of operations 
over the period in which employees are required to 
provide service. Liabilities initially incurred are based 
on the fair-value of equity instruments and are to be re-
measured at each subsequent reporting date until the 
liability is ultimately settled. The fair-value for employee 
share options and other similar instruments at the grant 
date are estimated using option-pricing models and 
any excess tax benefits are recognized as an addition 
to paid-in capital. Cash retained from the excess tax 
benefits is presented in the statement of cash flows as 
financing cash inflows. The provisions of this statement 
became effective as of January 1, 2006. See Note 11 
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. DPL’s cash and 
cash equivalents were $134.9 million at December 31, 
2007 and $262.2 million at December 31, 2006. DP&L’s 
cash and cash equivalents were $13.2 million at December 
31, 2007 and $46.1 million at December 31, 2006. At 
December 31, 2007, we had $37.0 million restricted 
funds held in trust relating to the issuance of the $90 
million pollution control bonds. These funds will be 
used to fund the pollution control capital expenditures.

Financial Instruments 

We apply the provision of FASB Statement of Financial 
Accounting Standards No. 115, “Accounting for Certain 
Investments in Debt and Equity Securities” (SFAS 
115), for our investments in debt and equity financial 
instruments of publicly traded entities and classify the 
securities into different categories: held-to-maturity and 
available-for-sale. Available-for-sale securities are car-
ried at fair value and unrealized gains and losses on 
those securities, net of deferred income taxes, are pre-
sented as a separate component of shareholders’ equi-
ty. Other-than-temporary declines in value are recog-

nized currently in earnings. Financial instruments clas-
sified as held-to-maturity are carried at amortized cost. 
The valuation of public equity security investments 
is based upon market quotations. The cost basis for 
public equity security and fixed maturity investments is 
average cost and amortized cost, respectively.

Financial Derivatives 

We follow FASB Statement of Financial Accounting 
Standards No. 133, “Accounting for Derivative 
Instruments and Hedging Activity” (SFAS 133), as 
amended. SFAS 133 requires that all derivatives be 
recognized as either assets or liabilities in the consoli-
dated balance sheets and be measured at fair value. 
Changes in the fair value are recorded in earnings 
unless they are designated as a cash flow hedge of 
a forecasted transaction or qualify for the normal pur-
chases and sales exception as discussed below. 

We use forward contracts and options to reduce 

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 genera-
tion facility availability. We use cash flow accounting 
under SFAS 133 guidance when the hedge is deemed 
to be effective and mark to market accounting when 
the hedge is not effective. See Note 10 of Notes to 
Consolidated Financial Statements.

Captive Insurance Subsidiary 

In addition to insurance provided through third-party 
providers, a wholly-owned captive subsidiary of DPL 
provides insurance coverage solely to us and to 
our subsidiaries. Insurance and Claims Costs on 
the consolidated balance sheets includes insurance 
reserves of approximately $20.0 million and $22.0 
million for 2007 and 2006, respectively. Such reserves 
are actuarially determined, in the aggregate, based 
on a reasonable estimation of insured events occur-
ring. There is uncertainty associated with the loss esti-
mates, 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. 

Pension and Postretirement Benefits

In September 2006, the FASB issued Financial 
Accounting Standards No. 158, “Employers’ Accounting

62  DPL Inc.

for Defined Benefit Pension and Other Postretirement 
Plans, an amendment of FASB Statements No. 87, 88, 
106 and 132(R)” (SFAS 158). This Statement requires 
an employer that is a business entity and sponsors 
one or more single-employer defined benefit plans to: 
recognize the funded status of a 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 the employer’s fiscal year-
end statement of financial position; and disclose in 
the notes to financial statements additional information 
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. This Statement 
is effective for fiscal years ending after December 15, 
2006, except for the measuring of plan assets at the 
employer’s fiscal year end, which is effective for 
fiscal years ending after December 15, 2008. We have 
adopted SFAS 158 effective December 31, 2006. 
We account and disclose pension and postretirement 
benefits in accordance with the provisions of SFAS 
158. See Note 9 of Notes to Consolidated Financial 
Statements.

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 consoli-
dated financial statements, as prescribed by GAAP, 
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, tax 
examinations and other matters discussed 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, 2007, cannot be reasonably determined.

Recently Issued Accounting Standards 

Accounting for Fair Value Measurements

In September 2006, the FASB issued Statement of 
Financial Accounting Standards No. 157, “Fair Value 
Measurements,” (SFAS 157) effective for fiscal years 
beginning after November 15, 2007. SFAS 157 applies 
whenever other standards require (or permit) assets 

or liabilities to be measured at fair value. SFAS 157 
clarifies the principle that fair value should be based on 
the assumptions market participants would use when 
pricing the asset or liability. In support of this principle, 
SFAS 157 establishes a fair value hierarchy that priori-
tizes the information used to develop those standards. 
The fair value hierarchy gives the highest priority to 
quoted prices in active markets and the lowest prior-
ity to unobservable data, for example, the reporting 
entity’s own data. Under SFAS 157, fair value measure-
ments would be separately disclosed by level within 
the fair value hierarchy. SFAS 157 does not expand 
the use of fair value in any new circumstances. In 
February 2007, the FASB issued Statement of Financial 
Accounting Standards No. 159, “The Fair Value Option 
for Financial Assets and Financial Liabilities – Including 
an amendment of FASB Statement No. 115” (SFAS 159) 
effective for fiscal years beginning after November 15, 
2007. SFAS 159 permits entities to choose to measure 
many financial instruments and certain warranty 
and insurance contracts at fair value on a contract-
by-contract basis. We will adopt SFAS 157 and SFAS 
159 on January 1, 2008. We have evaluated the 
impact of adopting SFAS 157 and SFAS 159, and have 
determined they will not have a material impact on 
our overall results of operations, financial position 
or cash flows.

Amendment of FASB Interpretation No. 39 “Offsetting 
of Amounts Related to Certain Contracts”

In April 2007, the FASB issued Staff Position FIN 39-1, 
“Amendment of FASB Interpretation 39,” (FSP FIN 39-1) 
effective for fiscal years beginning after November 
15, 2007. We will adopt FSP FIN 39-1 on January 1, 
2008. FSP FIN 39-1 amends paragraph 10 of FIN 39 to 
“permit a reporting entity to offset fair value amounts 
recognized for the right to reclaim cash collateral (a 
receivable) or the obligation to return cash collateral 
(a payable) against fair value amounts recognized for 
derivative instruments executed with the same counter-
party under the same master netting arrangement that 
have been offset in accordance with that paragraph.” 
We have evaluated the impact of adopting FSP FIN 
39-1 and have determined it will not have a material 
impact on our overall results of operations, financial 
position or cash flows.

Accounting for Income Tax Benefits of Dividends 
on Share-Based Payment Awards

In June 2007, the FASB ratified EITF Issue No. 06-11, 
“Accounting for Income Tax Benefits of Dividends on 
Share-Based Payment Awards,” (EITF 06-11) effective 
for fiscal years beginning after December 15, 2007. We 

DPL Inc. 

63

 
will adopt EITF 06-11 on January 1, 2008. The FASB 
ratified the EITF consensus that a realized income tax 
benefit from dividends that are charged to retained 
earnings, and are paid to employees for equity classi-
fied non-vested equity shares, should be recognized 
as an increase in additional paid-in-capital and should 
be included in the pool of excess tax benefits available 
to absorb potential future tax deficiencies on share-
based payment awards. We have evaluated the impact 
of adopting EITF 06-11 and have determined it will not 
have a material impact on our overall results of opera-
tions, financial position or cash flows.

Valuation of Employee Share Option Grants

In December 2007, the Securities and Exchange 
Commission (SEC) issued Staff Accounting Bulletin 
110 “Valuation of Employee Share Option Grants – an 
Amendment of SAB No. 107” (SAB 110). SAB 110 
states, that the staff will continue to accept, under cer-
tain circumstances, the use of the simplified method 
for estimating the term of plain vanilla stock options 
beyond December 31, 2007. We have evaluated the 
impact of adopting SAB 110 and have determined it 
will not have a material impact on our overall results of 
operations, financial position or cash flows.

Business Combinations

In December 2007, the FASB issued Statement of 
Financial Accounting Standards No. 141R, “Business 
Combinations,” (SFAS 141R) effective for fiscal years 

beginning after December 15, 2008. Under SFAS 
141R, an acquiring entity in a business combination is 
required to recognize all assets acquired and liabili-
ties assumed in the transaction. The revised standard 
also establishes the acquisition-date fair value as the 
measurement objective for all assets acquired and 
liabilities assumed. The rule requires an acquirer to 
disclose all of the information users may need to evalu-
ate and understand the nature and financial effect of 
the business combination. We are currently evaluating 
SFAS 141R and do not expect these new rules to have 
a material impact on our overall results of operations, 
financial position or cash flows.

Non-controlling Interests in 
Consolidated Financial Statements 

In December 2007, the FASB issued Statement of 
Financial Accounting Standards No. 160, “Non-
controlling Interests in Consolidated Financial 
Statements – an amendment of ARB No. 51,” (SFAS 
160) effective for fiscal years beginning after December 
15, 2008. SFAS 160 requires all entities to report 
non-controlling (minority) interests in subsidiaries as 
equity in the consolidated financial statements. Its 
intention is to eliminate the diversity in practice regard-
ing the accounting for transactions between an entity 
and non-controlling interests. We are currently evaluat-
ing the impact of SFAS 160 and do not expect these 
new rules to have a material impact on our overall 
results of operations, financial position or cash flows.

We apply the provisions of SFAS 71 to our regulated operations. This accounting standard defines regulatory 
assets as the deferral of costs expected to be recovered in future customer rates and regulatory liabilities 
as current cost recovery of expected future expenditures.

Regulatory liabilities are reflected on the consolidated balance sheets under the caption entitled “Other 

Deferred Credits”. Regulatory assets and liabilities on the consolidated balance sheets include:

Regulatory Assets

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.

Deferred recoverable income taxes represent deferred 
income tax assets recognized from the normalization 
of flow-through items as the result of amounts previ-
ously provided to customers. Since currently existing 
temporary differences between the financial statements 
and the related tax basis of assets will reverse in 
subsequent periods, deferred recoverable income 
taxes are amortized.

Pension and postretirement benefits represent the 
unfunded benefit obligation related to the transmis-
sion and distribution areas of our electric business. We 
have historically recorded these costs on the accrual 
basis and this is how these costs have been historically 
recovered through rates. This factor, combined with 
the historical precedents from the PUCO and the FERC, 
make these costs probable of future rate recovery.

Unamortized loss on reacquired debt represents costs 
associated with the redemption of a series of bonds 
financed by another issue. These costs are being 
amortized over the life of the original issue.

Electric Choice systems costs represent costs incurred 
to modify the customer billing system for unbundled 
rates and electric choice bills relative to other 
generation suppliers and information reports provided 
to the state administrator of the low-income electric 
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 repre-
sent costs incurred to join a Regional Transmission 
Organization (RTO) that controls the receipts and 
delivery of bulk power within the service area. These 
costs are being amortized over a 10-year period that 
commenced in October 2004. 

Deferred storm costs include costs incurred by us 
to repair damage from December 2004 and January 
2005 ice storms. We filed to recover these costs from 
retail ratepayers over a two year period. The PUCO 
approved our tariff as proposed and we began recov-
ering these deferred costs over a two-year period 
beginning August 1, 2006. 

PJM Interconnection, LLC (PJM) administrative costs 
contain the administrative fees billed by PJM to us as 

a member of the PJM RTO. Pursuant to a PUCO order 
issued on January 25, 2006, these deferred costs will 
be recovered over a 3-year period from retail ratepay-
ers beginning February 2006.

Power plant emission fees represent costs paid to the 
State of Ohio for environmental monitoring that are or 
will be recovered over various periods under a PUCO 
rate rider from customers.

Settlement system costs represent costs to implement 
a settlement system that reconciles the amount 
of energy a competitive retail electric service (CRES) 
supplier delivers to its customers and what its custom-
ers actually use. Based on case precedent in other 
utilities’ cases, the cost of this system is recoverable 
through DP&L’s next transmission rate case that will be 
filed at the FERC. The timing of this case is uncertain 
at this time.

PJM integration costs include infrastructure costs and 
other related expenses incurred by PJM and reim-
bursed by DP&L to integrate us into the RTO. Pursuant 
to a FERC order, the costs are being recovered over 
a 10-year period beginning May 2005 from wholesale 
customers within PJM. 

Rate case expenses represent costs incurred in 
connection with the Rate Stabilization Surcharge that 
was approved by the PUCO and implemented in 
January 2006. These costs are being amortized over 
a five-year period.

PJM transmission expansion costs represent costs 
incurred as a result of PJM Regional Transmission 
Expansion Plan (RTEP) cost assignments. On 
December 21, 2007, DP&L filed seeking PUCO 
authority to defer these costs for future recovery. 
These costs are included within Other costs.

Utility system of the future costs represent costs 
incurred as a result of studying and developing 
distribution system upgrades and implementation 
of advanced metering infrastructure, as well 
as DSM program development and various new 
customer programs. 

Other costs include consumer education advertising 
regarding electric deregulation and rate case and are 
or will be recovered over various periods.

Regulatory Liabilities

Asset retirement obligations – regulated property 
reflect an estimate of amounts recovered in rates that 
are expected to be expended to remove existing 
transmission and distribution property from service 
upon retirement.

68  DPL Inc.

Postretirement benefits reflect a regulatory liability that was recorded for the portion of the unrealized gain on our 
postretirement trust assets related to the transmission and distribution areas of our electric business. The company 
has historically recorded these transactions on the accrual basis and this is how these costs have historically been 
recovered through rates. This factor, combined with the historical precedents from the PUCO and the FERC, make 
it probable that these amounts will be reflected in future rates.

SECA (Seams Elimination Charge Adjustment) net revenue subject to refund represents our deferral of net revenues 
collected in 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, but no ruling has been issued. We began receiving and paying these transitional payments in 
May 2005. 

4  Ownership of Facilities

We and other Ohio utilities have undivided ownership interests in seven 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 (as well as investments in fuel inventory, plant materials and 
operating supplies) and capital additions are allocated to the owners in accordance with their respective ownership 
interests. As of December 31, 2007, we had $356 million of construction in progress at such facilities. Our 
share of the operating cost of such facilities is included in the Consolidated Statement of Results of Operations, 
and our share of the investment in the facilities is included in the consolidated balance sheets. 
Our undivided ownership interest in such facilities at December 31, 2007, is as follows:

5  Assets Sales

Peaker Sales

During 2006, in connection with DPLE’s (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 approxi-
mately $66 million. Darby Station consisted of six natu-
ral gas peaking units with a net book value of approxi-

mately $156 million. During the fourth quarter of 2006, 
DPL recorded a $71.0 million impairment 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, respec-
tively, in two separate transactions.

The assets and liabilities held for sale in DPL’s

On June 7, 2007, Miami Valley CTC, Inc. (indirect, wholly-owned subsidiary of DPL), sold its corporate aircraft 
and associated inventory and parts for $7.4 million. The net book value of the assets sold was approximately 
$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 approximately $6.0 million during the second quarter ending June 30, 2007, 
which is included in DPL’s operation and maintenance expense.

On February 13, 2005, DPL’s subsidiaries, 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 venture of AlpInvest Partners 
and Lexington Partners, Inc. Sales proceeds and any related gains or losses were recognized during 2005 
as the sale of each fund closed.

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 
transferred 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 alternative arrange-
ments resulted in a 2005 deferred gain of $27.1 million. DPL recognized $18.9 million of the deferred gain in 2006; 
and the remaining portion of the gain, $8.2 million, was recognized in the first quarter ended March 31, 2007 as all 
legal and economic considerations relating to the alternative closing arrangements were satisfied. Legal title to the 
final fund subject to the alternative arrangement was transferred in the third quarter ended September 30, 2007.

As a result of the May 21, 2007 settlement of the litigation with three former executives (see Note 15 of Notes 

to Consolidated Financial Statements), the three former executives relinquished all of their rights to certain 
deferred compensation, RSUs, MVE incentives, stock options and reimbursement of legal fees. The reversal of 
accruals related to the performance of the financial asset portfolio were 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 $8.2 million being recorded in discontinued operations related to 
the settlement of the executive litigation in the second quarter ending June 30, 2007.

At December 31, 2007, DPL’s scheduled maturities of long-term debt, including capital lease obligations, over 
the next five years are $100.7 million in 2008, $175.7 million in 2009, $0.6 million in 2010, $297.4 million in 2011, 
and none in 2012. 

At December 31, 2007, DP&L’s scheduled maturities of long-term debt, including capital lease obligations, 
over the next five years are $0.7 million in 2008, $0.7 million in 2009, $0.6 million in 2010 and none in 2011 and 
2012. Substantially all property of DP&L is subject to the mortgage lien securing the first mortgage bonds. 

On March 25, 2004, DPL completed a $175 million private placement of unsecured 8% Series Senior Notes 

due March 2009. The purchasers were granted registration rights in connection with the private placement 
under an Exchange and Registration Rights Agreement. Pursuant to this agreement, DPL was obligated to file an 
exchange offer registration statement by July 22, 2004, have the registration statement declared effective 
by September 20, 2004 and consummate the exchange offer by October 20, 2004. DPL failed (1) to have a regis-
tration statement declared effective and (2) to complete the exchange offer according to this timeline. As a result, 
DPL had been accruing additional interest at a rate of 0.5% per year for each of these two violations, up to an 
additional interest rate not to exceed in the aggregate 1.0% per year. As each violation was cured, the additional 
interest rate decreased by 0.5% per annum. DPL’s exchange offer registration statement for these securities 
was declared effective by the SEC on June 27, 2006. As a result, on June 27, 2006, DPL ceased accruing 0.5% 
of the additional interest. On July 31, 2006, DPL ceased accruing the other 0.5% of additional interest when the 
exchange of registered notes for the unregistered notes was completed.

On February 24, 2005, DP&L entered into an amendment to extend the term of its Master Letter of Credit 
Agreement with a financial lending institution for one year and to reduce the maximum dollar volume of letters of credit 
to $10 million. On February 17, 2006, DP&L renewed its $10 million agreement for one year. This agreement sup-
ports performance assurance needs in the ordinary course of business. This agreement was not renewed in 2007.

On March 1, 2007, pursuant to the Company’s 
strategy of reducing its long-term debt, DPL redeemed 
the $225 million 8.25% Senior Notes when they 
became due.

During the first quarter of 2006, the Ohio 

Department of Development (ODOD) awarded DP&L 
the ability to issue over the next three years up to 
$200 million of qualified tax-exempt financing from the 
ODOD’s 2005 volume cap carryforward. The financ-
ing is to be used to partially fund the ongoing flue 
gas desulfurization (FGD) capital projects. The PUCO 
approved DP&L’s application for this additional financ-
ing on July 26, 2006.

On September 13, 2006, the Ohio Air Quality 
Development Authority (OAQDA) issued $100 million 
of 4.80% fixed interest rate OAQDA Revenue Bonds 
2006 Series A due September 1, 2036. In turn, DP&L 
borrowed these funds from the OAQDA. The payment 
of principal and interest on the Bonds when due 
is insured by an insurance policy issued by Financial 
Guaranty Insurance Company. DP&L is using the 
proceeds from these borrowings to assist in financing 
its portion of the costs of acquiring, constructing, 
and installing certain solid waste disposal and air 
quality facilities at Miami Fort, Killen, and Stuart gener-
ating stations. 

On November 21, 2006, DP&L entered into a new 

$220 million unsecured revolving credit agreement 
replacing its $100 million facility. This new agreement 
has a five-year term that expires 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. This covenant is currently met. DP&L 
had no outstanding borrowings under this credit facil-
ity at December 31, 2007. Fees associated with this 
credit facility are approximately $0.2 million per year. 
Changes in credit ratings, however, may affect fees 
and the applicable interest rate. This revolving credit 
agreement also contains a $50 million letter of credit 
sub-limit. DP&L has certain contractual agreements 
for the sale and purchase of power, fuel and related 
energy services that contain credit rating related claus-
es allowing the counter parties to seek additional sure-
ty under certain conditions. As of December 31, 2007, 
DP&L had no outstanding letters of credit against the 
facility.

During the second quarter ended June 30, 2007, 
DPL entered into a short-term loan to DP&L for $105 
million. DP&L paid down $15 million of this loan during 
the third quarter ended September 30, 2007, and an 

additional $70 million during the fourth quarter ended 
December 31, 2007, leaving a current outstanding 
balance of $20 million. This short-term loan does not 
affect our debt covenants. Other than inter-company 
payables due to DPL, by DP&L, in the amount of $0.9 
million, there are no other inter-company debt collat-
eralizations or debt guarantees between DPL, DP&L, 
and their subsidiaries at December 31, 2007. None of 
the debt obligations of DPL or DP&L are guaranteed 
or secured by affiliates and no cross-collateralization 
exists between any subsidiaries.

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 is insured by an insurance policy issued by 
Financial Guaranty Insurance Company. On January 
30, 2008, FGIC’s credit rating was downgraded by 
Fitch Ratings from ‘AAA’ to ‘AA’ and remains on nega-
tive ratings watch. On January 31, 2008, FGIC’s credit 
rating was downgraded by Standard & Poor’s from 
‘AAA’ to ‘AA’ and placed on credit watch. On February 
14, 2008, FGIC’s credit rating was downgraded by 
Moody’s from ‘Aaa to A3.’ These downgrades, as well 
as the recent downgrades or pending downgrades of 
other major bond insurers, could result in DP&L’s vari-
able rate bonds having substantially higher interest 
rates in succeeding auctions and increase the risk that 
these bonds may have a failed auction. The maximum 
interest rate is capped at 12%. Management will con-
tinue to evaluate the current market conditions. If these 
conditions do not improve, we may redeem our vari-
able rate bonds and issue fixed rate bonds. We have 
sufficient liquidity to redeem the variable rate bonds 
using cash on hand or through funds available to 
us by our revolving credit line until fixed rate bonds 
are issued. DP&L is using the proceeds from these 
borrowings to assist in financing its portion of the costs 
of acquiring, constructing and installing certain solid 
waste disposal and air quality facilities at Miami Fort, 
Killen, Stuart and Conesville generating stations. These 
facilities are currently under construction and the pro-
ceeds from the borrowing have been placed in escrow 
with the trustee (the Bank of New York) and are being 
drawn upon only as facilities are built and qualified 
costs are incurred. In the event any of the proceeds 
are not drawn, DP&L would eventually be required 
to return the unused proceeds to bondholders. DP&L 
expects to draw down the remaining available funds 
from this borrowing over the next two years.

9  Pension and Postretirement Benefits

We sponsor 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 
compensation and years of service. We fund pension 
plan benefits as accrued in accordance with the mini-
mum 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 liabilities related to retirement benefits for 
certain active, terminated and retired key executives. 
These liabilities totaled approximately $0.9 million at 
December 31, 2007.

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 Supplemental Executive Retirement Plan 
(SERP) that was terminated as to new participants in 
2000. The Compensation Committee of the Board of 
Directors designates the eligible employees. Pursuant 
to the SEDCRP, we provide a supplemental 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. 
We have funded the union-eligible health benefit using 
a Voluntary Employee Beneficiary Association Trust. 
We adopted SFAS 158 “Employers’ Accounting 

for Defined Benefit Pension and Other Postretirement 
Plans, an amendment of FASB Statements No. 87, 88, 
106 and 132(R)” for the year ended December 31, 
2006. SFAS 158 requires that an entity’s funded status 
of its pension and other postretirement benefit obliga-
tions be recognized on the face of the financial state-
ments and not just in the footnotes.

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. 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.

The following tables set forth our pension and 

postretirement benefit plans’ obligations and assets 
recorded on the consolidated balance sheets as of 
December 31. The amounts presented in the fol-
lowing tables for pension include both the defined 
benefit pension plan and the Supplemental Executive 
Retirement Plan in the aggregate, and use a mea-
surement date of December 31, 2007. The amounts 
presented for post-retirement include both health and 
life insurance benefits and use a measurement date of 
December 31, 2007.

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 consideration 
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. 

On November 26, 2007, DP&L contributed $27.4 million in DPL common stock from its Master Trust assets 

to the Retirement Income Plan. This contribution fully funded the pension liability as of December 31, 2007. 
DPL common stock is now 9% of plan assets.

Our expected return on plan asset assumptions, used to determine benefit obligations, are based on 
historical long-term rates of return on investment, 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 reasonability 
and appropriateness. 

Our overall expected long-term rate of return on assets is approximately 8.50% for pension plan assets and 
approximately 6.75% for retiree benefit plan assets. This expected return is based exclusively on historical returns,

without adjustments. There can be no assurance of our ability to generate that rate of return in the future.

Our overall discount rate was evaluated in relation to the December 31, 2007 Hewitt Yield Curve, which 
represents a portfolio of top-quartile AA-rated bonds used to settle pension obligations. Peer data and historical 
returns were also reviewed to verify the reasonability and appropriateness of our discount rate used in the 
calculation of benefit obligations and expense.

10  Financial Instruments

Mark to Market 

In the normal course of business, DPL and DP&L enter 
into various financial instruments, including derivative 
financial instruments. A description of these financial 
instruments is as follows:

Derivatives

We use derivatives principally to manage the risk of 
changes in market prices for commodities. The deriva-
tives that we use to hedge these risks are governed 
by our risk management policies for forward contracts, 
futures, options, and swaps. Our net positions are 
continually assessed within our structured hedg-
ing programs to determine whether new or offsetting 
transactions are required. The objective of the hedg-
ing program is generally to mitigate financial risks 
while ensuring that sufficient volumes are available to 
meet our requirements. We monitor and value deriva-
tive positions monthly as part of our risk management 
processes. We use published sources for pricing when 
possible to mark positions to market. We rely on mod-
eled valuations only when no other method exists.

DPL and DP&L recognized $0.0 million and $3.2 
million in unrealized gains on derivative assets in OCI 
in 2007 and 2006, respectively. $1.5 million and $0.0 
million of unrealized losses on derivative liabilities 
were recognized in OCI in 2007 and 2006, respectively. 
Approximately $1.5 million of accumulated gains/
(losses) in OCI are expected to be reclassified to earn-
ings over the next twelve months. 

Cash Flow Hedges

Our risk management processes identify the relation-
ships between hedging instruments and hedged items, 
as well as the risk management objective and strategy 
for undertaking various hedge transactions. The mark-
to-market value of cash flow hedges as determined by 
current public market prices will continue to fluctuate 
with changes in market prices up to contract expira-
tion. The effective portion of the hedging transaction 
is recognized in OCI and transferred to earnings 
when the forecasted transaction takes place, while the 
impact of discontinued cash flow hedges is recognized 
in earnings. These instruments are used to hedge the 
risk of price changes for sales and purchases of 
power and capacity. All risk components were taken 
into account to determine the hedge effectiveness 
of the cash flow hedges. Power hedges are usually 
transacted over a 1 to 3 month period while capacity 
swaps are for the 12 month PJM year (June-May).

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 SFAS No. 133, 
“Accounting for Derivative Instruments and Hedging 
Activities,” as amended. Accordingly, such contracts 
are recorded at fair value with changes in the fair value 
charged or credited to the income statement in the 
period in which the change occurred. Contracts we 
enter into as part of our risk management program 
may be settled financially, by physical delivery, or net 
settled with the counterparty. 

Master Trust Assets

DP&L established a Master Trust to hold assets for the 
benefit of employees participating in DP&L’s Deferred 
Compensation Plan and other employee benefit 
purposes and these assets are not used for general 
operating purposes. These assets are primarily 
comprised of mutual funds and DPL common stock. 
The DPL common stock held by the Master Trust 
in DP&L’s consolidated balance sheet is eliminated 
in consolidation and is not reflected in DPL’s consoli-
dated balance sheet. These assets are valued using 
current public market prices on a quarterly basis. Any 
unrealized gains or losses are recognized in Other 
Comprehensive Income until the securities are sold. 
DPL recognized $6.2 million and $5.5 million of 

unrealized gains and $5.9 million and $3.8 million 
of unrealized losses in OCI in 2007 and 2006, respec-
tively. DP&L recognized $31.2 million and $41.1 
million of unrealized gains and $5.9 million and $3.8 
million of unrealized losses in OCI in 2007 and 
2006, respectively. No unrealized gains or losses are 
expected to be transferred to earnings in 2008.

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 Inc. 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 common stock with a fair value of $27.4 million 
to the Pension and resulting in a fully funded status at 
December 31, 2007.

Long-term Debt

Long-term debt is fair valued based on current public 
market prices for disclosure purposes only. Unrealized 

DPL Inc. 

79

 
gains or losses are not recognized in the financial statements, as long-term debt is presented at amortized cost in 
the financial statements. The long-term debt amounts include the current portion payable in the next twelve months 
and have maturities that range from 2008 to 2035.

The fair values of our financial instruments and debt are based on market quotes of similar instruments and 
represent estimates of possible value that may not be realized in the future. The table below presents the fair value 
and cost of these instruments at December 31, 2007 and 2006.

11  Stock-Based Compensation

As a result of the May 21, 2007 settlement of the litigation with three former executives (see Note 15 of the Notes to 
Consolidated Financial Statements), the three former executives relinquished all of their rights to certain deferred 
compensation, RSUs, MVE incentives, stock options and reimbursement of legal fees. A portion of this settlement 
included the forfeitures and cancellations of RSUs and stock options of 1.3 million and 3.6 million, respectively.

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 market price on the day of grant and the Directors’ RSUs are valued at the 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 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 correspond-
ing 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 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, 2007, there were no unvested stock options.

The schedule of option activity for the twelve months ended December 31, 2007 was as follows:

of December 31, 2007, none of which has vested. The non-vested RSUs will be paid in cash upon vesting 
and will vest as follows: 11,253 in 2008; 7,878 in 2009 and 3,845 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.

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

As of December 31, 2007, 2006, and 2005 liabilities recorded for outstanding RSUs were $0.6 million, 
$36.9 million and $34.5 million, respectively, which are included in “Other deferred credits” on the consolidated 
balance sheets. The decrease in the liability is due to the executive litigation settlement and the forfeiture of 
1.3 million RSUs. See Note 15 of Notes to Consolidated Financial Statements.

Performance Shares

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 FAS 123R. There is a three year 
requisite service period for each tranche of the performance shares.

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 
received a $54,000 retainer in RSUs on the date of the annual meeting. 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 shares, unless the Director chooses to 
defer receipt of the shares until a later date. The RSUs are valued at the closing stock price on 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 DPL’s 
option at the per-share prices indicated, plus cumula-
tive accrued dividends. 

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

ing, 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 distribut-
ed 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. As of year-end, all earnings reinvested in the 
business of DP&L were available for Common Stock 
dividends. DPL records dividends on preferred stock 
of DP&L as part of interest expense. We expect all 
2007 earnings reinvested in the business of DP&L to 
be available for DP&L common stock dividends, pay-
able to DPL.

In February 2000, DPL entered into a series of 
recapitalization transactions including the issuance 
of $550 million of a combination of voting preferred 
and trust preferred securities and warrants to an affili-
ate of investment company Kohlberg Kravis Roberts 
& Co. (KKR). As part of DPL’s 2000 recapitalization 
transaction, trust preferred securities sold to KKR had 
an aggregate face amount of $550 million, and were 
issued at an initial discounted aggregate price of $500 
million, with a maturity of 30 years (subject to accelera-
tion six months after the exercise of the warrants), and 
distributions at a rate of 8.5% of the aggregate face 
amount per year. DPL recognized the entire trust pre-
ferred securities original issue discount of $50 million 
upon issuance. 

In August 2001, DPL issued $300 million of trust 

preferred securities to institutional investors at 8.125% 
and $400 million of senior unsecured notes at 6.875%. 
The August 2001 trust preferred securities have a term 
of 30 years and the senior unsecured notes have a 
term of 10 years. In the fourth quarter of 2003, DPL 
adopted FIN46R and deconsolidated the DPL Capital 
Trust II, which resulted in transferring the August 2001 
trust preferred securities to the DPL Capital Trust II 
and establishing a note to Capital Trust II for $300 mil-
lion at 8.125%. In August 2005, DPL redeemed $105 
million of these Capital Securities, leaving $195 million 
outstanding.

The voting preferred shares (DPL Series B) were 

not redeemable, except at the option of the holder. 
DPL agreed to redeem such number so that at no time 
would the holder and its affiliates maintain an owner-
ship interest of greater than 4.9% of the voting rights 
of DPL. DPL’s Series B preferred shares may only be 
transferred or otherwise disposed of together with a 

corresponding number of warrants, unless the holder 
and its affiliates hold a greater number of warrants than 
DPL’s Series B preferred shares, in which case the 
holder may transfer any such excess warrants without 
transferring DPL’s Series B preferred shares. If the 
holder of a warrant wishes to exercise warrants that are 
not excess warrants, DPL will redeem simultaneously 
with the exercise of such warrants an equal number of 
DPL’s Series B preferred shares held by such holder. 
DPL repurchased 6,600,000 DPL Series B preferred 
shares on January 12, 2005 at par for an aggregate 
purchase price of $66,000. There are currently no 
Series B preferred shares outstanding. 

13  Common Shareholder’s Equity

DPL has 250,000,000 authorized common shares, 
of which 113,558,444 are outstanding at December 
31, 2007. DPL had 902,490 authorized but unissued 
shares reserved for its dividend reinvestment plan 
at December 31, 2007. The plan provides that either 
original issue shares or shares purchased on the open 
market may be used to satisfy plan requirements.

On July 27, 2005, DPL’s Board authorized the 
repurchase of up to $400 million of common stock 
from time to time in the open market or through private 
transactions. DPL completed this share repurchase 
program on August 21, 2006. In total, 14.9 million 
shares were repurchased at a cost of $400.0 mil-
lion. These Board-authorized repurchase transactions 
resulted in an 11.7% reduction of the outstanding stock 
of December 31, 2005 at an average price of $26.91 
per share. These shares are currently held as treasury 
shares. There were no other repurchases during 2007 
and 2006.

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 
business 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 cer-
tain attempted business combinations. The renewed 
plan expires on December 31, 2011. 

In February 2000, DPL entered into a series of 
recapitalization transactions including the issuance of 
$550 million of a combination of voting preferred and 
trust preferred securities and warrants to an affiliate of 
investment company KKR. As part of this recapitaliza-
tion transaction, 31.6 million warrants were issued. 
These warrants were sold for an aggregate purchase 
price of $50 million. The warrants are exercisable, in 
whole or in part, for common shares at any time dur-

86  DPL Inc.

ing the twelve-year period commencing on March 13, 
2000. Each warrant is exercisable for one common 
share, subject to anti-dilution adjustments (i.e., stock 
split, stock dividend). The exercise price of the war-
rants is $21.00 per common share, subject to anti-
dilution adjustments. 

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 
reserved authorized common shares sufficient to pro-
vide for the exercise in full of all outstanding warrants. 
During December 2004 and January 2005, Dayton 
Ventures, LLC requested that we transfer all of Dayton 
Ventures, LLC’s warrants to Lehman Brothers, Inc. 
(Lehman) in four transactions. Lehman has subse-
quently transferred a large number of these warrants 
to unaffiliated third parties. During one of these trans-
actions in 2005, Dayton Ventures, LLC agreed to sell 
back to DPL at par all of the outstanding 6,600,000 
voting preferred shares. As a result of the reduction 
of Dayton Ventures, Inc.’s warrant ownership below 
12,640,000, Dayton Ventures, LLC was no longer eli-
gible to receive an annual $1 million management, con-
sulting and financial services fee and it no longer had 
the right to designate one person to serve as a director 
of DPL and DP&L and no longer had the right to des-
ignate one person to serve as a non-voting observer of 
DPL and DP&L. Currently, Dayton Ventures, LLC does 
not have any ownership interest in DPL or DP&L.
During October 1992, our Board of Directors 
approved the formation of a Company-sponsored 
Employee Stock Ownership Plan (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 
Qualified Domestic Relations Order and 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 if already left the Company, 
10th anniversary of participation if already left the 
Company or termination after age 65. Distributions 
are made in cash unless the participant requests the 
distribution be made in Stock. A repurchase obligation 
exists for vested shares held by the ESOP if they can-
not be sold in the open market. The fair value of shares 
subject to the repurchase obligation at December 31, 
2007 is approximately $52.5 million. 

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. 
The loan bears interest at a fixed rate of 7.625%, pay-
able 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 pur-
chase 4.7 million shares of our common stock in the 
open market. As a result of the 1997 stock split, the 
ESOP held 7.1 million shares of our common stock. The 
cost of shares held by the ESOP and not yet released 
is reported as a reduction of shareholders’ equity. At 
December 31, 2007, common shareholders’ equity is 
reduced for the cost of 3.2 million unreleased shares 
held in suspense by the trust. The fair value of the 3.2 
million ESOP shares held in suspense at December 31, 
2007 was $95.3 million. When shares are committed 
to be released from the ESOP, compensation expense 
is recorded based on the fair value of the shares com-
mitted to be released, with a corresponding credit to 
our equity. Compensation expense associated with the 
ESOP, which is based on the fair value of the shares 
committed to be released for allocation, amounted to 
$9.0 million in 2007, $4.1 million in 2006 and $3.1 mil-
lion in 2005. 

For purposes of earnings per share (“EPS”) com-
putations and in accordance with SOP 93-6, we treat 
ESOP shares as outstanding if they have been allo-
cated to participants, released or committed to be 
released. As of December 31, 2007, the ESOP has 3.7 
million shares allocated to participants with an addi-
tional 0.2 million shares which have been released but 
unallocated to participants. ESOP cumulative shares 
outstanding for the calculation of earnings per share 
were 3.9 million in 2007, 3.4 million in 2006 and 3.2 
million in 2005.

DPL Inc. 

87

 
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 sooner terminated 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 the Company’s common 
stock were reserved for issuance under the EPIP. 

14  Earnings per Share

Basic earnings per share (EPS) are based on the weighted-average number of DPL common shares outstanding 
during the year. Diluted EPS are 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 this weighted-average computation are shares held by DP&L’s 
Master Trust Plan for deferred compensation and unreleased shares held in ESOP.

The following table represents common equivalent shares excluded from the calculation of diluted EPS 

because they were anti-dilutive. These shares may be dilutive in the future.

15  Executive Litigation

On May 21, 2007, we settled the 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 compensation, 
RSUs, MVE incentives, stock options and legal fees. The RSUs and stock options relinquished and forfeited 
were 1.3 million and 3.6 million, respectively. 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 certain contested compensation 
discussed above, all of these claims by all parties were settled and released.

As a result of this settlement during the second quarter ended June 30, 2007, DPL realized a net pre-tax 

gain in continuing and discontinued operations of approximately $31.0 million and $8.2 million, 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 sub-
sidiary. The MVE operations were discontinued in 2005 
with the sale of the financial asset portfolio. The $25 
million settlement expense was allocated between con-
tinuing and discontinued operations based on 
the proportionate share of continuing and discontinued 
obligations. The following table outlines the compo-
nents of DPL’s net pre-tax gain for continuing and 
discontinued operations:

As a result of this settlement during the second quarter 
ended June 30, 2007, DP&L realized a net pre-tax gain 
in continuing operations of $35.3 million. Accrued obli-
gations 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 following table out-
lines the components of DP&L’s net gain:

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 transaction dur-
ing the second quarter ended June 30, 2007, DPL and 
DP&L recorded a $3.2 million realized gain which is 
reflected in investment income.

16  Insurance Recovery

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 the 

second quarter ended June 30, 2007. 

On May 16, 2007, DPL and DP&L notified another 

of our insurers, Energy Insurance Mutual Limited, under 
an excess fiduciary liability policy, of our intent to 
pursue a claim for additional legal fees that DPL and 
DP&L incurred in defending claims made by the three 
former executives. That claim is pending.

17  Contractual Obligations, Commercial 
Commitments and Contingencies

DPL Inc. – Guarantees 

In the normal course of business, DPL enters into vari-
ous agreements with our wholly-owned generating 
subsidiary DPLE providing financial or performance 
assurance to third parties. These agreements are 
entered into primarily to support or enhance the cred-
itworthiness otherwise attributed to DPLE on a stand-
alone basis, thereby facilitating the extension of suffi-
cient credit to accomplish DPLE’s intended commercial 
purposes. Such agreements fall outside the scope of 
FASB Interpretation No. 45, “Guarantor’s Accounting 
and Disclosure Requirements for Guarantees, Including 
Indirect Guarantees of Indebtedness of Others.”

At December 31, 2007, DPL had $33.3 million of 

guarantees to third parties for future financial or perfor-
mance assurance under such agreements, on behalf 
of DPLE. The guarantee arrangements entered into 
by DPL with these third parties cover all present and 
future obligations of DPLE 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 guaran-
tees and recorded in our consolidated balance sheets 
was $0.5 million at December 31, 2007. 

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:

2010

$  7.7

We believe it is unlikely that either DPL or DP&L 
would be required to perform or incur any losses 
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. As of December 31, 2007, 
DP&L could be responsible for the repayment of 4.9%, or $36.5 million, of a $745 million debt obligation that 
matures in 2026. 

Other than the guarantees discussed above, DPL and DP&L do not have any other off-balance 

sheet arrangements that have or are reasonably likely to have a current or future material effect on our financial 
condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

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, 2007, these include:

price escalation in any given year. 

Limestone contracts:
DP&L has entered into various limestone contracts to 
supply limestone for its generating facilities. 

Reserve for uncertain tax positions
On January 1, 2007, we adopted Financial Accounting 
Standards Board (FASB) Interpretation No. 48, 
“Accounting for Uncertainty in Income Taxes” (FIN 48). 
As of December 31, 2007, our total reserve for uncer-
tain tax positions is $65.3 million including interest 
($42.5 million net of federal tax benefit). See Note 1 of 
Notes to Consolidated Financial Statements. 

Other contractual obligations:
As of December 31, 2007, DPL and DP&L had various 
other contractual obligations including non-cancelable 
contracts to purchase goods and services with various 
terms and expiration dates.

We enter into various commercial commitments, 
which may affect the liquidity of our operations. 
At December 31, 2007, these include: 

Credit facilities: 
In November 2006, DP&L replaced its previous $100 
million revolving credit agreement with a $220 million 
five year facility that expires on November 21, 2011. 
At December 31, 2007, there were no borrowings out-
standing under this credit agreement. DP&L has the 
ability to increase the size of the facility by an addi-
tional $50 million at any time.

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 contin-
gencies. See Note 1 of Notes to Consolidated Financial 
Statements. However, there can be no assurances 
that the actual amounts required to satisfy alleged 
liabilities from various legal proceedings, claims, 
tax examinations and other matters discussed below, 
and to comply with applicable laws and regulations, 
will not exceed the amounts reflected in our consoli-
dated financial statements. As such, costs, if 
any, that may be incurred in excess of those amounts 
provided as of December 31, 2007, cannot be 
reasonably determined.

Environmental Matters 

DPL, DP&L and our subsidiaries’ facilities and opera-
tions are subject to a wide range of environmental 
regulations and law. In the normal course of business, 
we have investigatory and remedial activities underway 
at these facilities to comply, or to determine compli-
ance, with such regulations. We have been identified, 
either by a government agency or by a private party 
seeking contribution to site clean-up costs, as a 
potentially responsible party (PRP) at two sites pursu-
ant to state and federal laws. We record liabilities for 
probable estimated loss in accordance with Statement 
of Financial Accounting Standards No. 5 (SFAS 5), 
“Accounting for Contingencies” as discussed in Note 1 
of Notes to Consolidated Financial Statements. 
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 opera-
tions and financial position.

State Income Tax Audit

On February 13, 2006, we received correspondence 
from the Ohio Department of Taxation (ODT) notify-
ing us that 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 result in a balance 
due of $90.8 million before interest and penalties. We 
have reviewed the proposed audit adjustments and 
are vigorously contesting the ODT findings and notice 
of assessment through all administrative and judicial 
means available. On March 29, 2006, we filed peti-
tions for reassessment with the ODT to protest each 
assessment as well as request corrected assessments 
for each tax year. On October 12, 2006, we signed 
a Memorandum of Understanding with the ODT that 
stated if the ODT’s positions are ultimately sustained 
in judicial proceedings, the total additional tax liability 
that we would be subject to for tax years 2002 through 
2004 would be no more than $50.7 million before inter-
est as opposed to the $90.8 million stated in the ODT’s 
correspondence of February 13, 2006. We believe 
we have recorded adequate tax reserves related to the 
proposed adjustments; however, we cannot predict 

DPL Inc.

the outcome, which could be material to our results 
of operations and cash flows.

We are also under audit review by various state 
agencies for tax years 2002 through 2006. We have 
also filed an appeal to the Ohio Board of Tax Appeals 
for tax years 1998 through 2001. Depending upon the 
outcome of these audits and the appeal, we may be 
required to increase our tax provision if actual amounts 
ultimately determined exceed recorded reserves. We 
believe we have adequate reserves in each tax juris-
diction but cannot predict the outcome of these audits.

Environmental

On April 2, 2007, the U.S. Supreme Court unani-
mously overturned the rulings of two lower courts and 
concluded that the CAA’s New Source Review (NSR) 
requirements are triggered when a major physical or 
operational change at a facility results in an increase in 
the facility’s annual emissions (Environmental Defense 
et al. v. Duke Energy Corp. et al.). The outcome of this 
case is significant to DP&L because it eliminates one 
of DP&L’s major arguments in the lawsuit filed against 
it by the Sierra Club. The Court decided that an annual 
rate of emissions could be used to determine if major 
modifications have been made to a plant as opposed 
to an hourly emission rate as Duke had argued. Using 
the annual rate makes it more likely that most plant 
modifications will be found to be “major” modifications, 
thus requiring EPA permits. DP&L can still defend 
against the allegations of NSR violations if it can 
establish that the activities at issue did not cause total 
annual emissions to increase or that the projects that 

resulted in increased emissions were undertaken for 
routine maintenance, repair and replacement activities.
In September 2004, the Sierra Club filed a law-
suit against the Company and the other owners of the 
Stuart generating station in the United States District 
Court for the Southern District of Ohio for alleged viola-
tions of the CAA, including issues similar to those pre-
sented in the Duke Energy case and other issues relat-
ing to alleged violations of opacity limitations. DP&L, 
on behalf of all co-owners, is leading the defense of 
this matter. A sizable amount of discovery has taken 
place and expert reports were filed at various times 
from May through September, 2007. On February 14, 
2008, upon the request of the Sierra Club, DP&L and 
the other owners of the Stuart generating station, the 
Court approved another sixty day stay of proceedings 
to permit the parties the opportunity to determine if a 
settlement of the case could be reached. Settlement 
negotiations are ongoing.

Governmental and Regulatory Inquiries 

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. We are cooperating with this 
investigation.

On or about June 24, 2004, the SEC commenced 

a formal investigation into the issues raised by the 
Memorandum. DPL and DP&L are cooperating with 
the investigation.

Report of Independent Registered Public Accounting Firm

The Board of Directors
DPL Inc.:

We have audited the accompanying consolidated balance sheets of DPL Inc. and subsidiaries (the Company) 
as of December 31, 2007 and 2006, 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, 2007. In connection with 
our audits of the consolidated financial statements, we have audited the consolidated financial statement schedule, 
“Schedule II – Valuation and Qualifying Accounts” for each of the years in the three-year period ended December 
31, 2007. We also have audited the Company’s internal control over financial reporting as of December 31, 2007, 
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 consoli-
dated 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 reason-
able 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, 2007 and 2006, and the results of their operations and 
their cash flows for each of the years in the three-year period ended December 31, 2007, in conformity with account-
ing principles generally accepted in the United States of America. Also in our opinion, the Company maintained, 
in all material respects, effective internal control over financial reporting as of December 31, 2007, based on criteria 
established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of 
the Treadway Commission (COSO) and the related financial statement schedule when considered in relation to the 
basic consolidated financial statements taken as a whole, present fairly in all material respects, the information 
set forth therein. 

As discussed in Note 1 to the consolidated financial statements, effective January 1, 2007 the Company 

adopted FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes.

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

We have audited the accompanying consolidated balance sheets of The Dayton Power and Light Company (DP&L) 
as of December 31, 2007 and 2006, and the related consolidated statements of results of operations, shareholder’s 
equity and cash flows for each of the years in the three-year period ended December 31, 2007. In connection 
with our audits of the consolidated financial statements, we have audited the consolidated financial statement 
schedule, “Schedule II – Valuation and Qualifying Accounts” for each of the years in the three-year period ended

based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring

effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on

statements and an opinion on DP&L’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

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, 
the financial position of DP&L as of December 31, 2007 and 2006, and the results of their operations and their cash 
flows for each of the years in the three-year period ended December 31, 2007, in conformity with accounting prin-
ciples generally accepted in the United States of America. Also in our opinion, DP&L maintained, in all material

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 proce-
dures 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 infor-
mation required to be disclosed by us in the reports

Management’s Report on Internal Control over

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 
management, 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 effective 
as of December 31, 2007. 

Our internal control over financial reporting as of 

December 31, 2007, has been audited by KPMG LLP, 
the independent registered public accounting firm that 
audited the financial statements contained herein, as
