Chairman’s Letter 

Dear Fellow Stakeholders:

In June of 2006, I was honored to be elected by the 
Board of Directors to the position of Non-Executive Chairman. 
It was an easy decision for me to accept this role. My fellow 
Directors are capable and dedicated to DPL’s success. 
They care deeply about DPL.

And over the past several years, DPL has made a 
number of sound strategic moves that have strengthened 
our Company and sharpened our focus on the electric utility 
business. These include selling the private equity funds, 
reducing debt by $450 million, and completing a $400 million 
stock buyback. We believe we have created a company 
with a strong foundation for the future.

There is evidence of this strong foundation in DPL’s 2006 
performance and improved profi tability. Shareholders were 
rewarded with a competitive return, including a 4% dividend 
increase in 2006 followed by another 4% increase in 2007. 
In addition, all three rating agencies now rate DPL debt 
as investment grade.

The year 2006 was a year of transition as well as a year 
of improvement. Bob Biggs chose to step down as Executive 
Chairman, although he remains a Director. We are fortunate 
to have his continued counsel. Likewise, Jim Mahoney, 
Chief Executive Offi cer, elected to move on to new challenges 
in the energy industry.

On behalf of the Board of Directors, I would like to 
express our sincere gratitude for the leadership and service 
that both of these talented individuals provided. Bob’s 
fi nancial and strategic acumen were critical to DPL’s success 
in the face of challenges that were unprecedented in its 
history. At the same time, Jim Mahoney’s day-to-day 
leadership was instrumental in the Company’s transition 
to a more open and transparent culture.

Now, we look to the future with excitement and anticipation. 
We are pleased to have Paul Barbas as our new 
Chief Executive Offi cer. Paul brings strong experience in both 
regulated and unregulated businesses, including 17 years 
at General Electric. I am confi dent that Paul will successfully 
capitalize on the positive momentum.

As Chairman, you have my commitment that DPL will 
continue to focus on delivering value to customers, investors, 
employees and the communities we serve.

Thank you for your investment in DPL Inc.

President & CEO’s Letter

To My Fellow DPL Stakeholders:

I am very excited to have joined the DPL team. 
DPL is a sound company with a bright future. On behalf 
of our employees, I am proud to report on the many 
signifi cant accomplishments of 2006.

Increased Earnings
Financially, DPL had a good year, with earnings per 
share from continuing operations up more than 8%. 

There were a number of factors driving this fi nancial 
performance. Retail revenues increased as we imple-
mented the fi rst year of DP&L’s fi ve-year rate stabilization 
plan. In addition, record base load generation output led 
to a 34% increase in wholesale sales. These positives 
more than offset the impact of mild weather and higher 
purchased power costs, increasing gross margin by 9%.

At the same time, fi nancial actions initiated in 2005 had 
a favorable impact, including lower interest expense due 
to debt reduction and the $400 million stock buyback.

Refl ective of these positive fi nancial results and a com-
mitment to shareholder return, the Board of Directors 
announced a 4% dividend increase in February of 2007.

The Strengths of DPL
After several months in my new position, it is clear we 
have a number of strengths.

(cid:129)  Our 1,500 employees are committed to delivering 
safe and reliable service to our customers. 
They are relentless in identifying improvements that 
enhance the level of service we provide.

(cid:129)  We are a solid electric utility. Our coal-fi red generating 
assets are cost competitive and the distribution 
system continues to deliver reliable service to more than 
500,000 customers in West Central Ohio.

(cid:129)  DP&L is currently the only utility in Ohio to have a rate 
stabilization plan in place through 2010. It allows the 
Company to recover increased fuel and environmental 
costs while protecting customers from potentially volatile 
energy markets. With discussions occurring in Ohio 
and other states about the future regulatory framework, 
having a rate plan in place for an extended period of 
time provides security for customers and investors alike.

(cid:129)  Strategically, DPL has taken a number of signifi  cant 
steps over the past several years to sharpen its 
focus. Most recently, we announced the sale of two 
peaking generation plants for over $150 million 
in cash. These sales better align generation capacity 
with generation needs.

Paul M. Barbas

Near-Term Focus
As we look to the future, near-term success will be 
determined by our ability to execute in several critical 
areas: customer satisfaction, generation performance 
and fuel procurement.

Customer Satisfaction, Reliable Service: The DP&L 
team takes great pride in their ability to provide reliable 
service, regardless of the weather. During 2006, the 
Company once again met and exceeded all regulatory 
reliability goals. We constantly communicate with our 
customers, and although pleased by customer percep-
tions of DP&L, during 2007 we plan to utilize customer 
feedback to further improve the value of the services we 
provide to our customers. At the same time, we will 
keep a vigilant eye on controlling costs.

Generation Performance: The priorities in the production 
business will remain operational excellence and cost 
control. Last year, DPL’s base load, coal-fi red generation 
– the plants that generate 97% of our electricity – 
produced the highest level of output in Company history.

The installation of fl ue gas desulfurization units, or 
scrubbers, will be completed at Killen Station during 
2007 and at various other units through 2009. The 
scrubbers will produce cleaner air for the environment 
and provide DPL with the potential to use lower 
cost coal. Our team will continue to focus on keeping 
this signifi cant project on track.

Effective Fuel Procurement: Each year, DPL burns 
approximately 7.5 million tons of coal. Managing the cost 
of this commodity is critically important to operating 
successfully within our retail rate structure. A challenge 
will be to determine the most cost-effective types of 
coals we can burn after the new scrubber systems come 
on-line at our Killen and Stuart Stations. The fuel strat-
egy going forward is to build in fl exibility while prudently 
controlling the risk of coal price volatility.

Long-Term Opportunities

For the long term, DPL will continue to keep a sharp eye 
on maintaining a healthy core business. In addition, 
we will actively participate in the discussions beginning 
to take shape in Ohio regarding the future of electric 
choice. To date, state regulators have done an admirable 
job of implementing a balanced approach, protecting 
consumers from price volatility while allowing reasonable 
cost recovery for fuel and environmental investments. 
DPL is committed to being part of a solution that 
works for all parties while helping to maintain Ohio’s 
competitive position in the global economy.

As the future regulatory direction unfolds, we will also 
explore and analyze opportunities for growth in areas 
directly related to our utility business. We will only 
act when the risks and returns are acceptable.

I look to the years ahead with great anticipation. 
The future holds both opportunities and challenges. 
With almost 100 years in business, adapting to change 
is ingrained in our culture, and we are committed to 
not just adapting but thriving as our industry 
continues to evolve.

Annual Highlights

4% Dividend Increase, Stock Buyback
DPL is committed to delivering long-term value 
and a competitive return to shareholders. 
To this end, DPL increased its common dividend 
4% in February of 2006 and again in February 
of 2007. The Company also completed a 
$400 million stock buyback program.

Debt Rating Upgrades
Moody’s, Standard & Poor’s and Fitch all 
now rate DPL debt investment grade. This reflects 
both the Company’s strengthened balance sheet, 
including debt reduction of $450 million that 
occurred in 2005, and its stable outlook.

Operational Performance
DPL continued to deliver quality customer 
service to its more than 500,000 retail customers 
by meeting and exceeding all reliability standards 
established by the Public Utilities Commission 
of Ohio. At the same time, our 2,500 megawatts of 
base load generation produced the highest output 
and achieved the second best effi ciency rating 
in Company history.

Rate Stabilization Plan – Year 1
DPL’s five-year rate stabilization plan provides 
customers and shareholders with a predictable 
and phased-in recovery of fuel and environmental 
expenses. The first phase of the plan was 
implemented in 2006, allowing the Company to 
recover approximately $65 million in additional net 
revenue. Generation rates will increase another 
5.4% for each of the next four years (2007–2010) 
to recover environmental investments.

$151.2 Million from Peaking Plant Sales 
After a thorough review of its generation portfolio, 
DPL announced an agreement to sell two peak-
ing sites, Darby Station and Greenville Station, for 
$151.2 million in cash. The transactions align our 
generation capacity with our generation needs 
while supplying cash for debt reduction and the 
funding of environmental investments.

New Chairman & Chief Executive Officer
As the Company completed a number of positive 
steps to sharpen its strategic focus, Robert Biggs 
stepped down as Executive Chairman. Glenn 
Harder, a Director since 2004, was elected Non-
Executive Chairman while Mr. Biggs remains on 
the Board of Directors. To complete the transition, 
Paul Barbas joined DPL as President and Chief 
Executive Officer, bringing valuable operational and 
strategic experience in both regulated and 
unregulated businesses.

DPL base load coal plants achieved their second 

best heat rate in the past 10 years. Heat rate, an 

efficiency measure, tracks the amount of electricity 

generated from fuel.

DPL installed a new distributed control system at 

Killen Station to enhance the plant’s overall 

efficiency. The investment paid off. Killen achieved 

the third best efficiency rating in its history.

Cost-Competitive Generation 

DPL’s base load generation portfolio consists 

of 2,500 megawatts of coal-fired generation. 
It is the workhorse of the DPL system. Combined, 
the seven plants produced 97% of 2006 total 
output and turned in another strong operational year.

Notable base load achievements included:

The highest output in Company history.

The second best equivalent availability in 
the past 10 years. In other words, the plants 
had a good year by being available to run 
when needed.

And, the second best efficiency rating in 
the past 10 years.

These results were made possible by ongoing 
investments in plant performance – both in terms 
of equipment and people.

At the 600-megawatt Killen Station, DPL installed a 
new distributed control system (DCS) to allow 
its plant operators to strengthen both availability and 
efficiency. As important as the new technology, 
the Company also installed a DCS simulator to train 
its operators on how best to use the new system to 
maximize plant performance.

At Stuart Station, DPL equipped Unit #1 with a new 
dense pack turbine. The design of the dense pack 
allows the turbine to convert more steam into electricity, 
increasing the unit’s efficiency and lowering fuel 
costs. Now, all four units at the 2,400-megawatt station 
have dense pack turbines, strengthening the plant’s 
ability to remain cost competitive.

With the mild weather that occurred in 2006, DPL 
sold its excess energy into the PJM wholesale market.   
Compared to 2005, wholesale sales were up 34% 
for the year, helping DPL hit the high end of its 2006 
earnings targets.

Delivering Power 
to 500,000 Customers

DDelivering reliable service to our customers and 

providing shareholders with a steady stream of income 
and cash fl ow is the touchstone of DPL’s regulated 
transmission and distribution business (DP&L).

Sharply focused on reliability, DP&L once again met or 
exceeded reliability standards set by the Public Utilities 
Commission of Ohio (PUCO) and consistently complied 
with regularly-scheduled PUCO audits. The Company 
also earned a 100% reliability compliance rating in an 
audit of its planning and operational standards performed 
by ReliabilityFirst Corporation, the North American 
Electric Reliability Council region for DP&L.

This steadfast performance is made possible by a 
team committed to continuous improvement. During 
2006, DP&L union and management employees 
worked together to design and implement a new “all-call” 
system to reward employees for prompt response 
during severe weather emergencies. “All-call” results 
have been outstanding.

In addition, the Company continuously invests in the 
reliability of its more than 16,000 miles of transmission 
and distribution lines. DP&L recently built three 
new substations to strengthen reliability and serve 
the growing areas of the Dayton region.

These types of efforts, combined with extensive 
planning, paid off during the summer as the area was 
hit with several intense heat waves. The system 
performed exceptionally well even as it approached 
peak loads for the second year in a row.

Beyond reliability, communication with customers 
is a critical component of quality customer service. To 
strengthen performance, DP&L restructured its call 
center. Employees are now organized into teams, with 
union employees taking an active leadership role. 
We are also working to meet the needs of an increasingly 
diverse customer base by adding several Spanish-
speaking customer service representatives.

Ongoing investment, continuous improvement and 
adapting to customer needs – these are just a few of the 
ways that DP&L employees are working around the 
clock to deliver.

Dayton Power and Light (DP&L), a regulated electric 

utility, serves more than 500,000 customers in West Central 

Ohio and provides shareholders with a solid foundation 

of income and cash fl ow.

Supporting Our Community

As a business, DPL recognizes that its success is 
directly tied to the success of West Central Ohio.

DPL and its 1,500 employees have a long-standing 
tradition of supporting Dayton and the 
surrounding communities, both through fi nancial 
initiatives and volunteer activities.

In 1985, the Company established the Dayton 
Power and Light Company Foundation as a means 
to enhance the quality of life in the communities it 
serves. In addition, DPL provides corporate sup-
port to a number of organizations, including those 
that promote regional economic development.

Together, DPL and the DP&L Foundation annually 
donate more than $1 million.

The efforts of the Company 
and the Foundation were 
honored by the Ohio Arts 
Council with the 2007 
Governor’s Award for 
Business Support of the 
Arts. Winners in six cat-
egories were selected from 63 
organizations located throughout the state.

As one letter in support of DPL’s nomination stated:

“The Dayton Power and Light Company has 
marked itself as a leader by spending the time and 
making the commitment to be a real partner in the 
ongoing conversation about the value of the arts in 
empowering the community.”

Organization

DPL Inc. (DPL) is a diversified regional energy com-
pany 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 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 
500,000 retail customers. DP&L also purchases retail 
peak load requirements from DPL Energy LLC (DPLE, 
one of DPL’s wholly-owned subsidiaries). Principal 
industries served include automotive, food process-
ing, 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 commer-
cial customers in West Central Ohio; MVE, Inc., which 
was primarily responsible for the management of our 
financial asset portfolio; and Miami Valley Insurance 
Company (MVIC), which is our captive insurance com-
pany 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. 

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.

full-time employees and 249 were part-time employees.

Peaking Unit Sales

Share Repurchase of DPL’s Common Stock

In connection with DPLE’s (subsidiary of DPL) decision 
to sell the Greenville Station and Darby Station electric 
peaking generation facilities, DPL concluded that an 
impairment charge for the Greenville Station and Darby 
Station assets was required. During the fourth quarter 
of 2006, DPL recorded a $71.0 million impairment 
charge to record the write-down of the assets to 
fair market value and other associated costs related 
to the sales.

On July 27, 2005, DPL’s Board authorized the repur-
chase of up to $400 million of common stock from time 
to time in the open market or through private transac-
tions. 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 a total cost of $400 million. These shares are 
currently held as treasury shares at DPL Inc. 

Pollution Control Bonds

Increase in Dividends on DPL’s Common Stock 

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 
then borrowed these funds from the OAQDA. DP&L 
is using the proceeds from this borrowing to assist 
in financing its portion of the costs of acquiring, con-
structing and installing certain solid waste disposal 
and air quality facilities at Miami Fort, Killen and Stuart 
Generating Stations. 

On February 1, 2007, DPL’s Board of Directors 
announced that it had raised the quarterly dividend 
to $0.26 per share payable March 1, 2007 to common 
shareholders of record on February 14, 2007. This 
increase results in an annualized dividend rate of 
$1.04 per share, or a 4% increase.

(a)  Amounts include 630 MW of peaking capacity relating to the Darby and Greenville stations 
that DPL entered into agreements to sell during the fourth quarter of 2006.

DPL’s present summer generating capacity, includ-
ing Peaking Units, is approximately 4,409 MW. Of this 
capacity, approximately 2,860 MW or 65% is derived 
from coal-fired steam generating stations and the 
balance of approximately 1,549 MW or 35% consists 
of combustion turbine and diesel peaking units. 

DP&L’s present summer generating capacity, 
including Peaking Units, is approximately 3,295 MW. 
Of this capacity, approximately 2,860 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 
ambient conditions and is higher in the winter than 
in the summer. Our all-time net peak load was 3,243 
MW, occurring July 25, 2005. 

Approximately 87% of the existing steam generat-

ing capacity is provided by certain units owned as 
tenants in common with (Duke Energy) The Cincinnati 
Gas & Electric Company (CG&E) or its subsidiary, 
Union Heat, Light & Power, and (AEP) Columbus 
Southern Power Company (CSP). As tenants in com-
mon, each company owns a specified undivided share 
of each of these units, is entitled to its share of capac-

ity and energy output, and has a capital and operating cost responsibility proportionate to its ownership share. 
DP&L’s remaining steam generating capacity (approximately 365 MW) is derived from a generating station owned 
solely by DP&L. Additionally, DP&L, CG&E and CSP own as tenants in common, 884 circuit miles of 345,000-volt 
transmission lines. DP&L has several interconnections with other companies for the purchase, sale and inter-
change of electricity.

In 2006, 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 vol-
ume needed to meet our retail and firm wholesale sales 
requirements for 2007 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 will be reduced in 2007 due to instal-
lation of emission control equipment at a portion of 
the Companies’ SO2 generation facilities. We do not 
expect to purchase SO2 allowances for 2007. The 
exact consumption of SO2 allowances will depend on 

market prices for power, availability of our generating 
units, the timing of FGD (flu gas desulfurization) com-
pletion and the actual sulfur content of the coal burned. 
We do not plan to purchase any nitrogen oxide (NOx) 
allowances for 2007.

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-opera-
tives and other distributors of electric energy are sub-
ject to regulation by the Federal Energy Regulatory 
Commission (FERC) under the Federal Power Act.

Ohio law establishes the process for determining 

rates charged by public utilities. Regulation of rates 
encompasses the timing of applications, the effective 
date of rate increases, the cost basis upon which the 
rates are based and other related matters. 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.

Competition and Regulation

Ohio Retail Rates 

and charges associated with the market development 
period that began January 2001. 

In 2003, the PUCO approved a Stipulation exe-
cuted by DP&L and other parties that extended the 
market development period through the end of 2005, 
and included provisions that generation rates may 
be modified as of January 1, 2006, by up to 11% of 
generation rates to reflect increased costs associated 
with fuel, environmental compliance, taxes, regulatory 
changes, and security measures. In 2006, the Ohio 
Supreme Court affirmed the PUCO’s Order approving 
the Stipulation.

On April 4, 2005, DP&L filed a request at the 
PUCO to implement a new rate stabilization surcharge 
effective January 1, 2006 to recover cost increases 
associated with environmental capital related opera-
tions and maintenance costs and fuel expenses. On 
November 3, 2005, DP&L entered into a settlement 
agreement that extended DP&L’s rate stabilization 
period through December 31, 2010. During this time, 
DP&L will continue to provide retail electric service at 
fixed rates with the ability to recover increased fuel and 
environmental costs through surcharges and riders. 
Specifically, the agreement provides for:

 A rate stabilization surcharge equal to 11% of gen-
eration rates beginning January 1, 2006 and continuing 
through December 2010. Based on 2004 sales, this 
rider is expected to result in approximately $65 million 
in net revenues per year.

 A new environmental investment rider to begin 

January 1, 2007 equal to 5.4% of generation rates, with 
incremental increases equal to 5.4% each year through 
2010. Based on 2004 sales, this rider is expected to 
result in approximately $35 million in annual net rev-
enues beginning January 2007, growing to approxi-
mately $140 million by 2010.

 An increase to the residential generation discount 
from January 1, 2006 through December 31, 2008, 
which is expected to result in a revenue decrease 
of approximately $7 million per year for three years, 
based on 2004 sales. The residential discount is 
accounted for in the $65 million net revenue stated 
above and will expire on December 31, 2008. 

Since January 2001, DP&L’s electric customers have 
been permitted to choose their retail electric genera-
tion supplier. DP&L continues to have the exclusive 
right to provide delivery service in its state certified 
territory. The PUCO maintains jurisdiction over DP&L’s 
delivery of electricity, the standard offer supply service 
that customers receive if they do not choose an alter-
native retail electricity supplier, and over other rates 

On December 28, 2005, the PUCO adopted the settle-
ment with certain modifications (RSS Stipulation). 
The PUCO ruled that the environmental rider will be 
bypassable by all customers who take service from 
alternate generation suppliers. Thus, future additional 
revenues are dependent upon actual sales and lev-
els of customer switching. Applications for rehearing 
were denied and the case was appealed to the Ohio 

DPL Inc.

Supreme Court by the Ohio Consumers’ Counsel on 
April 21, 2006. The Company cannot predict whether 
the Ohio Supreme Court will affirm the PUCO’s approv-
al of the RSS Stipulation, affirm it in part subject to 
modifications, or reject it. An oral argument has been 
set for April 17, 2007.

Consistent with the RSS Stipulation approved by 
the PUCO and prior orders, DP&L made a tariff filing 
to implement the environmental investment rider begin-
ning January 1, 2007, which was approved by the 
PUCO in November 2006. 

In 2005, DP&L made a tariff filing to recover previ-

ously deferred costs associated with administrative 
fees charged to DP&L under PJM’s FERC-approved 
tariffs. In January 2006, the PUCO approved the recov-
ery, effective February 1, 2006, which should result in 
approximately $8.5 million in additional revenue per 
year for three years and $6.0 million per year thereafter. 
In March 2006, the PUCO approved the recovery 
of costs and carrying costs associated with billing sys-
tem changes made to permit DP&L to provide billing 
services to Competitive Retail Electric Service (CRES) 
providers. These costs had previously been deferred 
for later recovery under a settlement approved in 2004. 
In separate orders issued in September and December 
2006, the Ohio Supreme Court affirmed the PUCO 
orders approving the settlement and approving the 
recovery of costs. This will result in approximately $7 
million in additional annual revenue beginning March 
2006 through 2010.

On September 1, 2005, DP&L requested the 
PUCO authority to recover distribution costs associ-
ated with storm restoration efforts for ice storms that 
took place in December 2004 and January 2005. In 
February 2006, DP&L filed updated schedules in sup-
port of its application. On July 12, 2006, the PUCO 
approved DP&L’s filing, allowing the Company to 
recover approximately $8.6 million in additional rev-
enues over a two-year period. See Note 3 of Notes to 
Consolidated Financial Statements.

Ohio Competitive Considerations and Proceedings

As of December 31, 2006, four unaffiliated marketers 
were registered as CRES providers in DP&L’s service 
territory. While there has been some customer switch-
ing to date, it represents less than 0.15 percent of 
sales in 2006. DPLER, an affiliated company, is also 
a registered CRES provider and accounted for 99.8% 
of the total kWh supplied by CRES providers within 
DP&L’s service territory in 2006. In addition, several 
communities in DP&L’s service area have passed ordi-
nances allowing the communities to become govern-

ment aggregators for the purpose of offering alternative 
electric generation supplies to their citizens. To date, 
none of these communities have aggregated their gen-
eration 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. In both 2005 and 2006, custom-
ers who elected to participate in the program were 
grouped together and collectively bid out to CRES 
providers. No bids were received in either year result-
ing in zero customer switching under the program. 
DP&L is required to execute the same process again 
in 2007. Future period effects cannot be determined at 
this time.

In August of 2006, an electric supply contract with 

Wright Patterson Air Force Base (WPAFB) expired. 
WPAFB is DP&L’s single largest retail customer and 
represents approximately 1% of its annual revenues. 
In November 2006, WPAFB signed a long-term agree-
ment to allow DPLER to supply competitive generation 
service to WPAFB through 2010.

On February 20, 2003, the PUCO requested com-

ments from interested stakeholders on the proposed 
rules for the conduct of a competitive bidding process 
that will take place at the end of the rate stabilization 
period. DP&L submitted comments in March 2003. The 
PUCO issued final rules on December 23, 2003. Under 
DP&L’s RSS Stipulation discussed above, these rules 
will not affect DP&L until January 1, 2011. However, 
the PUCO retains the authority to, at any time, require 
an Ohio electric utility to conduct a competitive bidding 
process to measure the market price of competitive 
retail generation.

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 on September 
18, 2006, and reply comments on October 2, 2006. If 
adopted by the Commission, the Staff’s recommenda-
tions may result in new regulatory requirements for 
Ohio investor owned utilities related to renewable ener-
gy standards, fuel sources, automated meter infrastruc-
ture, and time differentiated rate options for customers.

DP&L cannot predict the outcome of this proceeding 
nor the potential cost that may be associated with 
any new regulations that may be adopted. 

Federal Matters

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

As part of Ohio’s electric deregulation law, all of 
the state’s investor-owned utilities are required to join a 
Regional Transmission Organization (RTO). In October 
2004, DP&L successfully integrated 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 largest competitive whole-
sale electricity market and plans regional transmission 
expansion improvements to maintain 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. As discussed above in connection with 
the recovery of such costs in retail rates, these include 
significant administrative charges. Additionally, PJM’s 
role in administering the regional transmission grid and 
planning regional transmission expansion improve-
ments results in periodic proposals by PJM and other 
stakeholder members of PJM to the FERC to allocate 
and charge costs associated with the transmission 
system to various entities operating within PJM includ-
ing DP&L. DP&L and other interested parties have 
the right to intervene and offer counter-proposals. The 
FERC is currently considering how to allocate costs 
associated with new planned transmission facilities. 
None of these costs were allocated to DP&L under 
PJM’s original filing in the case, but other parties have 
proposed modified allocation methods that could result 
in allocations to DP&L. The FERC is also considering 
the justness and reasonableness of PJM’s transmission 

rate design for existing facilities. DP&L, along with ten 
other transmission owners, filed in support of PJM’s 
existing rate design, but other participants have pro-
posed rate designs that would shift significant costs to 
DP&L. Due to complexity of the issues and the number 
of competing proposals under consideration, DP&L 
cannot determine what effect the final outcome of this 
proceeding may have on its costs or the extent to 
which it may be able to recover such costs. 

As a member of PJM, the value of DPL’s genera-
tion capacity will be affected by changes in the PJM 
capacity construct. The new construct introduces a 
new Reliability Pricing Model (RPM) that will change 
the way generation capacity is priced and planned 
for by PJM. In September 2006, DP&L, along with 
most of the parties relating to the case, entered into a 
settlement agreement that generally retains the RPM 
concept as proposed by PJM, with certain modifica-
tions. The settlement was approved by the FERC on 
December 21, 2006. The economic effects of the new 
capacity market will vary depending on present and 
projected market conditions.

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. Several parties have sought rehearing of the 
FERC orders, which are still pending. The hearing was 
held in May 2006 and an initial decision was issued 
on August 10, 2006 that, if upheld by the Commission, 
would reduce the amount of SECA charges DP&L and 
other parties are permitted to recover. DP&L, among 
others, have taken exception to the initial decision. A 
final Commission 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 Commission’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 

DPL Inc. 

11

 
(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, pres-
ervation of a diverse fuel supply for electricity genera-
tion and energy efficiency. Also in response to the 
Energy Policy Act of 2005, the FERC issued a Notice 
of Proposed Rulemaking to amend its regulations to 
incorporate the criteria any entity must satisfy to qualify 
to be an Electric Reliability Organization (ERO) that 
will propose and enforce reliability standards subject 
to FERC approval. The proposed rule also included 
related matters on delegating ERO authority, the cre-
ation of advisory bodies and reporting requirements. In 
October 2006, the FERC also approved new manda-
tory reliability standards to be effective mid-2007, with 
requirements applying to certain assets and activities 
of DP&L and DPL. The new regulations include poten-
tial penalties for failure to comply with these standards. 
DPL is currently assessing the compliance plans in 
place to comply with similar, but voluntary, reliability 
standards administered by the North American Electric 
Reliability Council and believes that it will be in full 
compliance with the new mandatory standards when 
they become effective.

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 ener-
gy requirements. Approximately 1% of total electricity 
sales in 2006 represented sales to these municipalities. 

Environmental Considerations

DPL, DP&L and our subsidiaries’ facilities and opera-
tions are subject to a wide range of environmental 
regulations and laws. 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 record liabilities for 
probable estimated loss in accordance with Statement 
of Financial Accounting Standards No. 5 (SFAS 5), 
“Accounting for Contingencies.” To the extent a proba-
ble 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 information available at 
the time. DPL, through its captive insurance subsidiary, 

MVIC, has an actuarial calculated reserve for envi-
ronmental matters. We evaluate the potential liability 
related to probable losses quarterly and may revise our 
estimates. Such revisions in the estimates of the poten-
tial liabilities could have a material effect on our results 
of operations, financial position or cash flows.

DP&L’s coal-fired units are subject to the acid rain 
provisions of the Clean Air Act and the NOx and Ozone 
Transport rule. All of the SO2 and NOx emissions data 
submitted to the United States Environmental Protection 
Agency (USEPA) pursuant to these provisions for 2005 
and the first quarter 2006 were recorded and reported 
in compliance with USEPA regulations. Subsequently 
DP&L detected a malfunction with its emission moni-
toring system at one of its generation stations 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 operating results or financial position. 

Environmental Regulation and Litigation Related 
to Air Quality 

Regulation Proceedings – Air

In 1990 the federal government amended the Clean Air 
Act (CAA) to further regulate air pollution. Under the 
law, the USEPA sets limits on how much of a pollutant 
can be in the air anywhere in the United States. The 
CAA allows individual states to have stronger pollution 
controls, but states are not allowed to have weaker pol-
lution 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 pro-
grams 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 
lawsuits filed by numerous states and environmental 
organizations challenging the final rules. As a result 
of the stay, the Ohio Environmental Protection Agency 
(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 elec-

12  DPL Inc.

tric 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 pending before 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 emis-
sion levels to projected actual emission levels after 
the modification. A third option that tests emissions 
increase based upon emissions per unit of energy 
output is also available for comment. We cannot pre-
dict the outcome of this rulemaking 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 as 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 pro-
ceedings, the petitions or the pending litigation, CAIR 
has had and will have a material effect on our opera-
tions. Phase I of CAIR incentivizes the installation of 
flue gas desulfurization (FGD) equipment and continual 
operation of the currently installed Selective Catalytic 
Reduction equipment. As a result, DP&L is proceeding 
with the installation of FGD equipment at various 
generating units.

On January 30, 2004, the USEPA published its 

proposal to restrict mercury and other air toxics from 
coal-fired and oil-fired utility plants. The final Clean Air 
Mercury Rule (CAMR) was signed March 15, 2005 
and was published on May 18, 2005. The final rules 
will have a material effect on our operations. We antici-
pate that the FGD equipment being installed to meet 
the requirements of CAIR may be adequate to meet 
the Phase I requirements of CAMR effective January 1, 

2010. We expect that additional controls will be 
needed to meet the Phase II requirements of CAMR 
that go into effect January 1, 2018. On March 29, 2005, 
nine states sued USEPA, opposing the regulatory 
approach taken by USEPA. On March 31, 2005, various 
groups requested that USEPA stay implementation of 
CAMR. On August 4, 2005, the United States Court of 
Appeals for the District of Columbia denied the motion 
for stay. USEPA is expected to initiate reconsideration 
proceedings on one or more issues. We cannot predict 
the outcome of the reconsideration proceedings or 
pending litigation.

Under the CAIR and CAMR cap and trade pro-
grams for SO2, NOx and mercury, we estimate we will 
spend more than $225 million from 2007 through 2009 
to install the necessary pollution controls. If CAMR 
litigation results in plant specific mercury controls, our 
costs may be higher. Due to the ongoing uncertainties 
associated with the litigation of the CAMR, we cannot 
project the final costs at this time.

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

USEPA its recommendations for eight-hour ozone 
nonattainment boundaries for the metropolitan areas 
within Ohio. On April 15, 2004, the USEPA issued 
its list of ozone non-attainment designations. DP&L 
owns and/or operates a number of facilities in counties 
designated as non-attainment with the ozone national 
ambient air quality standard. DP&L does not know at 
this time what future regulations may be imposed 
on its facilities and will closely monitor the regulatory 
process. Ohio EPA will have until April 15, 2007 to 
develop regulations to attain and maintain compliance 
with the eight-hour ozone national ambient air qual-
ity standard. Numerous parties have filed petitions for 
review. DP&L cannot predict the outcome of USEPA’s 
reconsideration petitions.

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 Ohio EPA will have 
three years to develop regulations to attain and main-
tain compliance with the PM 2.5 national ambient air 

DPL Inc.

quality standard. 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, providing 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

Pending before the U.S. Supreme Court is a proceed-
ing, Environmental Defense v. Duke Energy (Duke 
Energy) that does not involve the Company as a party 
but may have a significant effect on the outcome of 
litigation described below that involves allegations of 
violations of the CAA. A key issue in that litigation that 
may be dispositive with respect to other pending cases 
is what test to apply for measuring whether modifica-
tions to electric generating units should trigger appli-
cation of New Source Review (NSR) standards under 
the CAA. In general terms, the dispute is whether to 
measure pre- and post-modification emissions based 
on the rate of emissions per hour of operation or based 
on total emissions over time. The latter test, if applied, 
could trigger NSR requirements for equipment replace-
ments that result in a plant running more often because 
it is more economical or dependable, even if the emis-
sions rate per hour of operation does not change. 
A ruling is expected in the first or second quarter of 
2007. The Company cannot predict the outcome of 
the Duke Energy case. Moreover, in each of the cases 
identified below, there may be case-specific facts and 
allegations that may cause a judge to find that the U.S. 
Supreme Court’s ruling is based on different facts and 
allegations and is therefore not controlling in the case 
before the judge. 

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 that may be decided 
by the Supreme Court 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 dis-
covery has taken place and expert reports are sched-
uled to be filed at various times from May through 
September, 2007. Dispositive motions are to be filed in 
January 2008. No trial date has been set yet. 

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 Corporation (now 
part of Duke Energy) and two subsidiaries for alleged 
violations of the CAA at various generation units oper-
ated by PSI Energy, Inc. and CG&E, including genera-
tion units co-owned by DP&L (Beckjord 6 and Miami 
Fort 7). In August 2006, the Seventh Circuit upheld the 
district court’s 2005 ruling that an increase in annual 
emissions could trigger the permitting requirements of 
the CAA even if there were no increase in hourly emis-
sions per hour of operations.

In November 2004, the State of New York and 
seven other states filed suit against the American 
Electric Power Corporation (AEP) and various subsid-
iaries, alleging various CAA violations at a number of 
AEP electric generating facilities, including Conesville 
Unit 4 (co-owned by CG&E, DP&L and Columbus 
Southern Power (CSP)). AEP, on behalf of all co-own-
ers, is leading the defense of this matter. During 2006, 
a number of procedural and discovery-related disputes 
were resolved by the Southern District Court of Ohio. 
Discovery is ongoing. 

In July 2004 and November 2004, various resi-

dents of the Village of Moscow, Ohio notified CG&E, 
as the operator of Zimmer (co-owned by CG&E, DP&L 
and CSP), of their intent to sue 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. 
One lawsuit was dismissed on procedural grounds. 
Several counts of the remaining suit have been dis-
missed because they were based on activity outside 
the statute of limitations. 

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 State Implementation Plan (SIP) or (2) bring a 
civil action seeking injunctive relief and civil penalties 
of up to $27,500 per day for each violation. To 

14  DPL Inc.

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 6) 
and CSP (Conesville 4) and co-owned by DP&L 
were referenced in these actions. Numerous northeast 
states have filed complaints or have indicated that they 
will be joining the USEPA’s action against CG&E and 
CSP. DP&L was not identified in the NOVs, civil com-
plaints or state actions. 

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 
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 is undertaking studies at two 
facilities but cannot predict the impact such studies 
may have on future operations or the outcome of the 
remanded rulemaking.

In May 2004, the Ohio EPA issued a final National 
Pollutant Discharge Elimination System permit for J.M. 
Stuart Station that continued the station’s 316(a) vari-
ance which exempts DP&L from having to meet the 
temperature Standards in the Ohio River. During the 
three-year term of the permit, DP&L conducted a ther-
mal discharge study to evaluate the technical feasibility 
and economic reasonableness of water cooling meth-

ods other than cooling towers. We cannot predict the 
impact 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 a site 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. Although the 
information available to DP&L does not demonstrate 
that it contributed hazardous substances to the site, 
DP&L will seek from USEPA a de minimis settlement at 
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 contrib-
uted hazardous substances to the 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. 
We cannot predict the impact of the draft rules on 
future operations.

DPL’s construction additions were $352 million, $180 million and $98 million in 2006, 2005 and 2004, respectively, 
and are expected to approximate $310 million in 2007. 

DP&L’s construction additions were $349 million, $178 million and $93 million in 2006, 2005 and 2004, respec-

tively, and are expected to approximate $310 million in 2007. Planned construction additions for 2007 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 
$605 million in capital projects, approximately 40% of which is to meet changing environmental standards. Our

ability to complete capital projects and the reliability of 
future service will be affected by our financial condi-
tion, the availability of internal funds and the reason-
able cost of external funds. We expect to finance our 
construction additions in 2007 with a combination of 
cash on hand, short-term financing, tax-exempt debt 
and cash flows from operations.

consider to be the most significant to your decision to 
invest in our stock. If any of these events occurs, our 
business, financial position or results of operation could 
be materially affected.

The electric industry in Ohio is partially deregulated 

Before 2001, electric utilities provided electric genera-
tion, transmission and distribution services as a single 
product to retail customers at prices set by the PUCO. 
In 1999, Ohio enacted legislation, effective January 
1, 2001, that partially deregulated utility service, mak-
ing 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 deregula-
tion law were premised on the assumption that the 

wholesale generation market and, in turn, the retail 
generation 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 
Commission and the utilities, including DP&L, have 
worked out plans to provide market-based pricing for 
generation 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 
wholesale and retail electric generation markets have 
developed. 

Moreover, the uncertainty of the future of the whole-

sale and retail markets could cause the Ohio General 
Assembly to revisit the issue of competition and cus-
tomer choice.

Switching by DP&L’s customers to unaffiliated 
CRES providers could occur in the future, despite 
insignificant activity to date. 

Although retail generation service has been a competi-
tive service since January 1, 2001, the competitive 
generation market has not developed in DP&L’s ser-
vice territory to any significant degree. The following 
are factors that could result in increased switching by 
customers to CRES providers in the future:

 Voluntary Enrollment Program

As part of a settlement in a PUCO proceeding, DP&L 
initiated, in November 2004, a VEP to encourage cus-
tomers to change electric suppliers. Although the VEP 
did not result in a significant increase in the number 
of customers switching to CRES providers in 2005 or 
2006, the VEP will be initiated again in 2007 and could 
produce different results. 

 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, 2006, five 
CRES providers have been certified by the PUCO to 

16  DPL Inc.

■
■
■
provide generation service to DP&L customers. One 
of those five, DPL Energy Resources, Inc. (DPLER), 
is an affiliate of DPL. Although DPLER supplied 99.8% 
of the total kWh consumed by customers served by 
CRES providers in DP&L’s service territory in 2006, 
at the end of 2006 there was a slight increase in unaf-
filiated CRES provider activity. There has been zero 
residential customer 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 pro-
vided CRES providers offer prices below DP&L’s stan-
dard offer. 

DP&L has agreed to provide service at pre-determined 
rates through December 31, 2010, which limits its 
ability to pass through its costs to customers. 

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 new Rate Stabilization 
Surcharge was implemented that recovered approxi-
mately $65 million additional revenue in 2006, net 
of customer discounts and considering less than a full 
twelve months recovery due to the timing of the PUCO 
order. The new environmental investment rider could 

result in approximately $35 million additional revenue 
in 2007, 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 suppliers. 
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 prevailing market prices for electricity, it would not 
necessarily be able to charge rates that produce timely 
or full recovery of its expenses. DP&L has historically 
maintained 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, includ-
ing but not limited to those relating to fuel, coal and 
purchased power, compliance with environmental regu-
lation, reliability initiatives, and capital expenditures 
for the maintenance or repair of its plants or other 
properties. Furthermore, the RSS Stipulation is currently 
subject to an appeal to the Ohio Supreme Court, the 
result of which cannot be determined.

There are uncertainties relating to the operation and 
continued development of Regional Transmission 
Organizations (RTOs). DP&L has turned over operation-
al control of its high voltage transmission functions to 
PJM and much of its generation is subject to dispatch 
by PJM and is therefore subject to PJM’s market rules.

On October 1, 2004, in compliance with Ohio law, 
DP&L turned over control of its transmission func-
tions and fully integrated into PJM. The price at which 
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 trans-
actions that are not pre-arranged are subject to market 
conditions at PJM. The rules governing the various 
regional power markets also change from time to time 
which could affect DP&L’s cost and revenues. DP&L 
incurs fees and costs to participate in the Regional 
Transmission Organization (RTO). We may be limited 
with respect to the price at which power may be sold 
from certain generating units, and we may be required 
to expand our transmission system according to 
decisions made by the RTO rather than our internal 
planning process. While RTO transmission rates were 
initially designed to be revenue neutral, various propos-
als and proceedings currently taking place at FERC 

DPL Inc. 

17

 
■
may cause transmission rates to change from time to 
time. In addition, developing rules associated with the 
allocation and methodology of assigning costs associ-
ated 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 new Reliability 
Pricing Model (RPM). RPM will be effective in mid-
2007, and will provide forward and locational pricing 
for generation capacity. The financial impact of RPM on 
DP&L will depend on a variety of factors, including the 
market behavior of various participants, and as such 
is unknown at this time. 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 DPL.

We rely principally on coal as the fuel to operate 
virtually all of the power plants that serve our 
customers daily. 

Some of our coal suppliers have not performed their 
contracts as promised and have failed to timely deliver 
all coal as specified under their contracts. 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 failure is for a short period 
of time, DP&L can absorb the irregularity due to exist-
ing 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

Greenhouse gas (GHG) emissions, consisting primarily 
of carbon dioxide emissions, are presently unregulated. 
Numerous bills have been introduced in Congress 
to regulate GHG emissions, but to date none have 
passed. Future regulation of GHG emissions is uncer-
tain. However, such regulation would be expected to 
impose costs on our operations. Such costs could 
include measures as advanced by various constituen-
cies, including a carbon tax; investments in energy 
efficiency; installation of CO2 emissions control tech-
nology, to the extent such technology exists; purchase 
of emission allowances, should a trading mechanism 
be developed; or the use of higher-cost, lower CO2 
emitting fuels. We will continue to make prudent invest-
ments in energy efficiency that reduces our GHG 
emissions intensity.

Flue Gas Desulfurization Project

We are currently constructing flue gas desulfurization 
(FGD) facilities at five units located at our J. M. Stuart 
and Killen Electric Generating Stations. Construction of 
the FGD facilities at each unit is scheduled to be com-
pleted in phases commencing mid-year 2007 through 
2009. 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 
adversely affect our ability to operate or may substan-
tially increase our cost to operate these electric gen-
erating stations under federal environmental laws and 
regulations that become effective in 2010. For those 
electric generating stations where we are co-owners 
but do not operate, significant construction delays may 
substantially increase our pro-rata share of the cost to 
operate those facilities beginning in 2010.

PJM Infrastructure Risks

Annually, PJM, the regional transmission organization 
that provides transmission services for a large por-
tion of the Midwest United States, performs a review 
of the capital additions required to provide reliable 
electric transmission services throughout its territory. 
PJM allocates the costs of constructing these facili-
ties to the applicable entity that will benefit from the 
new construction. FERC is authorized to provide rate 
recovery to utilities for the costs they incur to construct 
these transmission facilities. To date, we have not been 
required to construct any new facilities nor have we 
been assigned any costs as a result of PJM’s annual 
review, but there is no guarantee that we will not be 
assigned some costs or be required to construct facili-
ties in the future.

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 $17.21 and a high of $28.72. 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.

The following are additional factors, including, but not 
limited to, regulation and competition, economic 

18  DPL Inc.

conditions, reliance on third parties, operating results 
fluctuations, regulatory uncertainties and litigation, 
warrant exercise, internal controls and environmental 
compliance, that may affect our future results.

Regulation and Competition

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 
environmental compliance, fuel and purchased power 
costs and investments made under traditional regu-
lation through rates; and changes to the frequency 
and timing of rate increases could affect our results 
of operations and financial condition. Changes in our 
customer base, including municipal customer aggrega-
tion, could lead to the entrance of competitors in our 
marketplace, affecting our results of operations and 
financial condition. Additionally, financial or regulatory 
accounting principles or policies imposed by govern-
ing bodies can increase our operational and monitoring 
costs affecting our results of operations and financial 
condition.

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.

During the past few years, the merchant energy 

industry in many parts of the United States has suf-
fered from oversupply of merchant generation and a 
decline in trading and marketing activity. As a result of 
these market conditions, we continue to evaluate the 
carrying values of certain long-lived generation assets.

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.

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 31,560,000 
warrants at their discretion until March 12, 2012. 
As a result, DPL could be required to issue up to 
31,560,000 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, 
affecting any existing guidance on EPS and affect 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. 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, poli-

DPL Inc. 

19

 
cies, 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 financial condition, cash flows or results of 
operations.

Environmental Compliance

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

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 is currently engaged in sig-
nificant capital improvements of five units at the Stuart 
and Killen Generating Stations for the reduction of SO2, 
Congress could approve legislation 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. 

Employees

Many of our employees are under a collective bargain-
ing agreement. If we are unable to negotiate future 
collective bargaining agreements, we could experience 
work stoppages which may affect its business and 
operating results.

Substantially all property and plant of DP&L is sub-

ject to the lien of the mortgage securing DP&L’s First

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 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 proceed-
ings, claims, 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, 2006, cannot be reasonably determined.

Former Executive Litigation

On August 24, 2004, DPL, and its subsidiaries DP&L 
and MVE, filed a Complaint (and subsequently, amend-
ed complaints) against Mr. Forster, Ms. Muhlenkamp 
and Mr. Koziar (the Defendants) in the Court of 
Common Pleas of Montgomery County, Ohio asserting 
legal claims against them relating to the termination 
of the Valley Partners Agreements, challenging the 
validity of the purported amendments to the deferred 
compensation plans and to the employment and con-
sulting agreements, including MVE incentives, with 
the Defendants, and the propriety of the distributions 
from the plans to the Defendants, and alleging that 
the Defendants breached their fiduciary duties and 
breached their consulting and employment contracts. 
DPL, DP&L and MVE seek, among other things, 
damages in excess of $25,000, disgorgement of all 
amounts improperly withdrawn by the Defendants from 
the plans and a court order declaring that DPL, DP&L 
and MVE have no further obligations under the consult-
ing and employment contracts due to those breaches.

The Defendants have filed their answers (and sub-

sequently, amended answers) denying liability and filed 
counterclaims (and subsequently, amended counter-
claims) against DPL, DP&L, MVE, various compensa-
tion plans (the Plans), and current and former employ-
ees and current and former members of our Board of 
Directors. These counterclaims, as amended, allege 
generally that DPL, DP&L, MVE, the Plans and the indi-
vidual defendants breached the terms of the employ-
ment and consulting contracts of the Defendants and 
the terms of the Plans. They further allege theories of 
breach of fiduciary duty, breach of contract, promissory 
estoppel, tortious interference, conversion, replevin 
and violations of ERISA under which they seek distribu-
tion of deferred compensation balances, conversion of 
stock incentive units, exercise of options and payment 
of amounts allegedly owed under the contracts and the 
Plans. Defendants’ counterclaims also demand pay-
ment of attorneys’ fees. 

On March 15, 2005, Mr. Forster and Ms. 

Muhlenkamp filed a lawsuit in New York state court 
against the purchasers of the private equity invest-
ments in the financial asset portfolio and against out-
side counsel to DPL and DP&L concerning purported 
entitlements in connection with the purchase of those 
investments. DPL, DP&L and MVE are not defendants 
in that case; however, DPL, DP&L and MVE are par-
ties to an indemnification agreement with respect to the 
purchaser defendants. On August 18, 2005, the Ohio 
court issued a preliminary injunction against Mr. Forster 
and Ms. Muhlenkamp that precludes them from pursu-
ing certain key issues raised by Mr. Forster and Ms. 
Muhlenkamp in their New York lawsuit that are identical 
to the issues raised in the pending Ohio lawsuit in the 
New York court or any other forum other than the Ohio 
litigation. In addition, the New York court has stayed 
the New York litigation pending the outcome of the 
Ohio litigation. Mr. Forster and Ms. Muhlenkamp have 
appealed the preliminary injunction and the appeal is 
pending at the Ohio Supreme Court.

The trial commencement date for this case is set 

for April 30, 2007.

Cumulatively through December 31, 2006, we 
have accrued for accounting purposes, obligations of 
approximately $56 million to reflect claims regarding 
deferred compensation, estimated MVE incentives and/
or legal fees that Defendants assert are payable per 
contracts. We dispute Defendants’ entitlement to any of 
those sums and any other sums the Defendants assert 
are due to them and, as noted above, we are pursuing 
litigation against them contesting all such claims.
On or about June 24, 2004, the SEC com-
menced a formal investigation into the issues raised 

by the Memorandum (see Note 17 of the Notes to the 
Consolidated Financial Statements). Although the SEC 
has not taken any significant action in furtherance 
of their investigation during 2006, we stand ready to 
cooperate with their investigation. 

On May 28, 2004, the U.S. Attorney’s Office for 

the Southern District of Ohio, assisted by the Federal 
Bureau of Investigation, notified us that it has initiated 
an inquiry involving the subject matters covered by 
our internal investigation. Although the U.S. Attorney’s 
office and the FBI have not taken any significant action 
in furtherance of their investigation during 2006, we 
stand ready to cooperate with their investigation. 

 On June 24, 2004, the Internal Revenue Service 
(IRS) began an audit of tax years 1998 through 2003 
and issued a series of data requests to us including 
issues raised in the Memorandum. The staff of the IRS 
requested that we provide certain documents, includ-
ing but not limited to, matters concerning executive/
director deferred compensation plans, management 
stock incentive plans and MVE financial statements. 
On September 1, 2005, the IRS issued an audit report 
for tax years 1998 through 2003 that showed proposed 
changes to our federal income tax liability for each 
of those years. The proposed changes resulted in a 
total tax deficiency, penalties and interest of approxi-
mately $23.9 million as of December 31, 2005. On 
November 4, 2005, we filed a written protest to one 
of the proposed changes. On April 3, 2006, the IRS 
conceded the proposed changes that we filed a writ-
ten protest to and issued a revised audit report for 
tax years 1998 through 2003. The revised audit report 
resulted in a total tax deficiency, penalties and interest 
of approximately $1.2 million. We had previously made 
a deposit with the IRS of approximately $1.3 million that 
we requested on April 14, 2006 be applied to offset 
the $1.2 million tax deficiency, penalties and interest 
for tax years 1998 through 2003. The Joint Committee 
on Taxation completed its review of the revised audit 
report for tax years 1998 through 2003 and sent us a 
letter dated June 16, 2006 stating that it took no excep-
tion to the revised audit report.

Insurance Recovery Claim

On January 13, 2006, we filed a claim against one 
of our insurers, Associated Electric & Gas Insurance 
Services (AEGIS), under a fiduciary liability policy 
to recoup legal fees associated with our litigation 
against three former executives. An arbitration of this 
matter was held on August 4, 2006. The arbitration 
panel ruled on or about September 12, 2006 that the 
AEGIS policy does not require an advance of defense 
expenses to us. Rather, the arbitration panel stated that 

DPL Inc. 

21

 
we are required to file a written undertaking as a condi-
tion precedent to repay expenses finally established 
not to be insured. We have filed a written undertaking 
with AEGIS and will continue to pursue resolution of the 
claim through mediation and arbitration in 2007.

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 2004. 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.

Labor Relations Unasserted Claim

In September 2006, we became aware of an unassert-
ed claim under the Fair Labor Standards Act concern-
ing the calculation of overtime rates for our unionized 
workforce. By agreement of Local #175 and DP&L, we 
jointly submitted the claim to a neutral third party who 
ruled in favor of DP&L’s position. As a result of this 
decision, Local #175 has decided not to pursue any 
claim against DP&L.

Environmental

Pending before the U.S. Supreme Court is a proceed-
ing, Environmental Defense v. Duke Energy (Duke 
Energy) that does not involve DP&L as a party but may 
have a significant effect on the outcome of litigation 
described below that involves allegations of violations 
of the CAA. A key issue in that litigation that may be 
dispositive with respect to other pending cases is what 
test to apply for measuring whether modifications to 
electric generating units should trigger application of 
New Source Review (NSR) standards under the CAA. 
In general terms, the dispute is whether to measure 
pre- and post-modification emissions based on the rate 
of emissions per hour of operation or based on total 
emissions over time. The latter test, if applied, could 
trigger NSR requirements for equipment replacements 
that result in a plant running more often because it is 
more economical or dependable, even if the emissions 
rate per hour of operation does not change. A ruling is 
expected in the first or second quarter of 2007. DP&L 
cannot predict the outcome of the Duke Energy case. 
Moreover, in each of the cases identified below, there 
may be case-specific facts and allegations that may 
cause a judge to find that the U.S. Supreme Court’s 
ruling is based on different facts and allegations and is 
therefore not controlling in the case before the judge. 
In September 2004, the Sierra Club filed a law-
suit against DP&L and the other owners of the Stuart 
Generating Station in the United States District Court 
for the Southern District of Ohio for alleged violations 
of the CAA, including issues that may be decided by 
the Supreme Court in the Duke Energy case and other 
issues relating to alleged violations of opacity limita-
tions. 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 are scheduled to 
be filed at various times from May through September, 
2007. Dispositive motions are to be filed in January 
2008. No trial date has been set yet. 

Additional information relating to legal proceedings 

involving DPL and DP&L is contained in Item 1 – 
Environmental Considerations, Item 1 – Competition 
and Regulation, and Item 8 – Note 15 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 year-end, all earnings reinvested in the 
business of DP&L were available for DP&L common 
stock dividends. We expect all 2006 earnings reinvest-
ed in the business of DP&L to be available for DP&L 
common stock dividends, payable to DPL.

On February 1, 2006, our Board of Directors autho-
rized a 4% dividend increase on DPL’s common stock, 
raising the annual dividend on common shares from 

$0.96 per share to $1.00 per share. These dividends 
were paid in each quarter of 2006.

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 
will be paid each quarter during 2007.

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, 2006, is disclosed in 
Item 12 – Security Ownership of Certain Beneficial 
Owners and Management and Related Stockholder 
Matters, which incorporates such information by

Business Overview 

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 86% 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. Historically, DPL and DP&L have filed 
separate SEC filings. Beginning with this report and in 
the future, DPL Inc. and The Dayton Power and Light 
Company will file combined SEC reports on an interim 
and annual basis.

DPL is a regional electric energy and utility com-

pany and through its principal subsidiary, DP&L, is 
primarily engaged in the generation, transmission and 
distribution 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 cus-
tomer 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 
focused on the operating efficiency of these power 
plants and maintaining their availability.

We operate and manage transmission and distribu-

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

ronment. The electric utility industry has historically 
operated in a regulated environment. However, in 
recent years, there have been a number of federal 
and state regulatory and legislative decisions aimed at 
promoting competition and providing customer choice. 
Market participants have therefore created new busi-
ness models to exploit opportunities. The marketplace 
is now comprised of independent power producers, 
energy marketers and traders, energy merchants, 
transmission and distribution providers and retail 
energy suppliers. There have also been new market 
entrants and activity among the traditional partici-

pants, such as mergers, acquisitions, asset sales and 
spin-offs of lines of business. In addition, transmission 
systems are being operated by Regional Transmission 
Organizations (RTOs). 

As part of Ohio’s electric deregulation law, all of the 

state’s investor-owned utilities were required to join an 
RTO. DP&L successfully integrated its 1,000 miles of 
high-voltage transmission into the PJM Interconnection, 
L.L.C. (PJM) RTO in October 2004. As an RTO, PJM’s 
role is to administer an electric marketplace and ensure 
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. 

2006 Financial Overview 

As more fully discussed in later sections of this 
MD&A, the following were the significant themes 
and events for 2006:

 DPL’s revenues increased 8% over 2005 resulting 
from the rate stabilization surcharge and other regu-
lated asset recovery riders improving gross margin and 
profitability. DPL’s fuel, purchased power costs, and 
operation and maintenance increased over 2005 by 
4%, 19% and 21%, respectively. DPL’s cash flow from 
operations of $308.7 million was in line with the cash 
flow from operations of $314.7 million in 2005.

is using the proceeds from these borrowings to assist 
in financing its portion of the costs of acquiring, con-
structing and installing certain solid waste disposal 
and air quality facilities at Miami Fort, Killen and Stuart 
Generating Stations. 

 On July 27, 2005, DPL’s Board authorized the repur-

chase 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. These Board-authorized 
repurchase transactions resulted in 14.9 million shares 
being repurchased, or 11.7% of the outstanding stock 
at December 31, 2005 at an average price of $26.91 
per share. These shares are currently held as treasury 
shares at DPL. 

Results of Operations – DPL Inc. 

DPL’s results of operations include the results of its 
subsidiaries, including the consolidated results of 
its principal subsidiary The Dayton Power and Light 
Company (DP&L) and all of DP&L’s consolidated 
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.

 In connection with DPLE’s decision to sell the 

Greenville Station and Darby Station electric peaking 
generation facilities, DPL concluded that an impair-
ment charge for the Greenville Station and Darby

of 2006, DPL recorded a $71.0 million impairment 
charge to record the fair market write-down of the 
assets and other associated costs related to the sale.

DPL Inc. – 2006 Compared to 2005 

For the year ended December 31, 2006, basic earn-
ings per share of $1.24 decreased $0.20 from the 
same period in 2005. The decline was primarily 
due to a $0.32 per share decrease in Earnings from 
Discontinued Operations reflecting lower investment 
income and lower gains on the sale of investments. 
Most of the investments were sold during 2005. Basic 
earnings per share for Earnings from Continuing 
Operations were $0.09 higher in 2006 compared to 
2005. This increase is the result of higher revenues 
relating to the impact of the rate stabilization plan and 
lower interest expense, partially offset by a $71.0 mil-
lion impairment charge for the peaking units, higher 
fuel and purchased power costs and higher operation 
and maintenance expenses. 

DPL Inc. – 2005 Compared to 2004 

For the year ended December 31, 2005, basic earn-
ings per share of $1.44 decreased $0.37 from the 
same period in 2004. The decline was primarily 
due to a $0.36 per share decrease in Earnings from 
Discontinued Operations reflecting lower investment 
income, partially offset by the gain on the sale of 
investments (In February 2005, DPL agreed to sell its 
respective interests in forty-six private equity funds). 
Basic earnings per share for Earnings from Continuing 
Operations were $0.02 higher in 2005 compared to 
2004. This increase is the result of higher revenues 
relating to higher retail sales volume and ancillary 
revenues associated with the participation in PJM. 
Also contributing to this increase were lower operation 
and maintenance expenses driven by lower corporate 
costs, higher investment income and lower interest 
expense related to debt refinancing in 2004. These 
increases were partially offset by higher fuel and pur-
chased power costs and a $61.2 million charge for the 
early redemption of debt.

For 2005, basic earnings per share includes a 
$0.03 after-tax charge related to the cumulative effect 
of a change in accounting for asset retirement obliga-
tions at certain power generating stations.

DPL Inc. – Revenues 

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 
million primarily related to a 34% increase in sales 
volume (935 GWh) resulting in a $45.8 million volume 
variance, partially offset by a decrease in wholesale 
average rates resulting 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. 
RTO ancillary revenues primarily consist of compensa-
tion for use of DP&L’s transmission assets, regulation 
services, reactive supply and operating reserves. 

For the year ended December 31, 2005, revenues 

of $1,284.9 million increased $85 million, or 7% from 
$1,199.9 million for the same period in 2004. This 
increase was primarily the result of increased retail 
sales volume, higher average rates for wholesale 
revenues, and ancillary revenues associated with 
participation in PJM that was partially offset by lower 
wholesale sales volume. Retail revenues increased 
$29.8 million, primarily resulting from increased sales 
volume of $32.8 million and $2.8 million in higher 
average rates, partially offset by $5.8 million in lower 
miscellaneous retail revenues reflecting transmis-
sion services provided in 2004 that are now provided 
through PJM. Residential customers comprised the 
bulk of the increase in sales volume reflecting greater 
weather extremes experienced in 2005 compared to 
2004 as cooling degree days were up 39% to 1,075 
in 2005 compared to 771 in 2004 and heating degree 
days were up 4% to 5,702 in 2005 compared to 5,500 
in 2004. Wholesale revenue decreased $1.8 million, 
primarily related to a $37.2 million decline in sales vol-
ume that was nearly offset by a $35.4 million increase 
related to higher average market rates. For 2005, ancil-
lary revenues from RTOs were $74.4 million compared 
to $17.9 million for 2004, as we did not participate in 
PJM until October 2004. 

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 

DPL Inc. – Margins, Fuel and Purchased Power 

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 

DPL Inc. 

27

 
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 purchase 
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. 

For 2005, gross margin of $814.7 million 
decreased by $9.0 million from $823.7 million for 
2004. As a percentage of total revenues, gross margin 
decreased by 5.2 percentage points to 63.4% from 
68.6%. This decline is primarily the result of increased 
fuel and purchased power costs, partially offset by an 
increase in revenues, principally from RTO ancillary 
revenues and higher average wholesale rates. Fuel 
costs, which include coal, gas, oil and emission allow-
ance costs, increased by $73.8 million or 28% for 2005 
compared to the same period in 2004 primarily result-
ing from higher average fuel prices of $64.1 million as 
well as increased generation of $9.7 million. Purchased 
power costs increased by $20.2 million for 2005 
compared to 2004 primarily resulting from increased 
charges of $36.2 million associated with operating in 
PJM (we did not participate in PJM until October 2004) 
and $28.2 million related to higher average market 
prices, partially offset by $44.2 million related to lower 
purchased power volume.

For 2006, operation and maintenance expense 
increased $46.4 million or 21% compared to 2005 
year primarily resulting from a $13.5 million increase in 
legal fees primarily related to the litigation with former 
executives; a $10.4 million increase in power produc-
tion costs consisting of $4.1 million of coal brokering 
credits received in 2005 that were not received in 2006 
and increased operating and maintenance expenses of 
$3.1 million which related to cost of removal and peak-
er engine repairs; $5.5 million in PJM administrative 
fees, including $2.5 million deferred in 2005 by PUCO 
authority (rate relief was granted in February 2006); 
$5.1 million increase in the low-income assistance pro-

For 2005, operation and maintenance expense 
decreased $18.1 million or 8% compared to 2004 as 
a result of lower corporate costs that were partially 
offset by increased electric production, transmission 
and distribution expenses. Corporate costs declined 
from the prior year primarily resulting from a decrease 
of $8.3 million in Directors’ and Officers’ liability insur-
ance premiums; approximately $5.8 million related 
to the decreased level of activity regarding various 
internal and governmental investigations as well as 
the securities litigation; $5.8 million in lower executive

lion of lower benefits costs (a decrease of $2.8 million 
for a 2004 adjustment in disability reserves was nearly 
offset by an increase in pension costs of $2.1 million). 
These decreases were partially offset by a $4.5 million 
increase in electric production, transmission, and distri-
bution costs, primarily related to generation operations 
costs for lime used for pollution control and electric 
production boiler maintenance costs as well as higher 
costs related to electric distribution operation and 
maintenance. 

DPL Inc. – Impairment of Peaking Stations 

In connection with DPLE’s decision to sell the 
Greenville Station and Darby Station electric peaking 
generation facilities, DPL concluded that an impair-
ment charge for the Greenville Station and Darby 
Station assets was required. Greenville Station consists 
of four natural gas peaking units with a net book value 
of approximately $66 million. Darby Station consists 
of six natural gas peaking units with a net book value 
of approximately $156 million. DPLE plans to sell the 
Greenville and Darby Station assets for $49 million and 
$102 million, respectively. These sales are expected to 
take place during the first half of 2007.

During the fourth quarter of 2006, DPL recorded 

a $71.0 million impairment charge to record the fair 
market write-down of the assets and other associated 
costs related to the sale. These assets are now held for 
sale and are no longer being depreciated these assets. 
There was no such activity in 2005. See Note 14 of the 
Notes to the Consolidated Financial Statements.

DPL Inc. – Depreciation and Amortization

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.

Depreciation and amortization expense was $3.2 

million higher in 2005 as compared to 2004 primar-
ily as a result of completed projects in the distribution 
area (including new services, line transformers, poles, 
station equipment and overhead and underground 
conductor) and in the production area (mainly due to 
the SCRs for Stuart, Killen and Zimmer) that were put 
into service in the second quarter of 2004.

DPL Inc. – Amortization of Regulatory Assets 

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 regula-
tory assets reflects $2.6 million for the amortization 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; $1.2 million for the amortization of incremental 
2004/2005 severe storm costs; $0.3 million for the 
amortization of costs incurred to integrate DP&L into 
the PJM system; and $0.2 million for the amortization of 
the Rate Stabilization Surcharge rate case expenses. 
For 2005, amortization of regulatory assets 

increased $1.3 million to $2.0 million compared to the 
same period in 2004 primarily resulting from PJM start-
up costs amortization of $1.1 million and PJM integra-
tion costs amortization of $0.2 million reflecting DP&L’s 
entrance into the PJM market on October 1, 2004.

DPL Inc. – Investment Income 

For 2006, investment income decreased $33.1 million 
to $17.8 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 in foreign 
currency translation gains realized in 2005 for the liq-
uidation of investments denominated in Euros, and a 
$4.8 million decrease in interest income resulting from 
lower cash balances in 2006 compared to 2005.

For 2005, investment income increased by $43.0 

million compared to 2004 primarily resulting from a 
net gain on the disposal of public equity and income 
investments of $23.5 million and from $18.5 million in 
interest income, principally from new short-term invest-
ments relating to a cash surplus from the sale of the 
private equity portfolio. 

DPL Inc. – Interest Expense 

For 2006, interest expense decreased $35.5 million, 
or 26%, compared to the same period in 2005 
resulting from the debt reduction that occurred in 
2004 and 2005 and a higher capitalized interest of 
$10.9 million in 2006 compared to 2005 associated 
with our major construction projects.

For 2005, interest expense decreased $22.5 
million, or 14%, compared to 2004 due to the debt 
reduction of $462.6 million and a full year impact of 
the $500 million debt retirement completed in 2004 
(partially financed with a $175 million note). 

DPL Inc. – Charge for Early Redemption of Debt 

In 2005, DPL recorded $61.2 million in charges 
resulting from premiums paid for the early redemption 
of debt, including write-offs of unamortized debt 
expense and debt discounts.

DPL Inc. – Other Income (deductions) 

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 

DPL Inc. 

29

 
the sale of pollution control emission allowances. 
There were no sales of pollution control emission 
allowances during 2006. 

For 2005, other income was $9.7 million greater 
than 2004 primarily reflecting $3.5 million of additional 
gains realized in 2005 over 2004 resulting from sales 
of pollution control emission allowances; $1.6 million 
of lower fees resulting from the 2004 cancellation and 
replacement of DP&L’s revolving credit facility and 
our term loan termination and $1.5 million from the 
2004 write-off of the remaining term loan debt expense 
resulting from our term loan termination. 

DPL Inc. – Income Tax Expense 

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.

For 2005, income tax expense from continuing 
operations increased $13.4 million compared to 2004 
resulting from higher income, increased accrual for 
open tax years and lower state tax coal credits.

On June 30, 2005, Governor Taft signed House Bill 

66 into law which significantly changed the tax struc-
ture 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 taxpayers 
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 reduced by $1.5 mil-
lion while income taxes from discontinued operations 
were increased by $1.3 million as a result of the tax law 
change. Other applicable provisions of House Bill 66 
have been reflected in the consolidated financial 
statements.

DPL Inc. – Discontinued Operations, Net of Tax 

On February 13, 2005, our 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 as the sale of each fund closed. Among 
other closing conditions, each fund required the 
transaction to be approved by the respective general 

partner of each fund. During 2005, MVE and MVIC 
completed the sale of their interests in forty-three and 
a portion of one of those private equity funds resulting 
in a $46.6 million pre-tax gain ($53.1 million less $6.5 
million professional fees) from discontinued operations 
and provided approximately $796 million in net 
proceeds, including approximately $52 million in net 
distributions from funds while held for sale. As part 
of this pre-tax gain, DPL realized $30 million that was 
previously recorded as an unrealized gain as part of 
other comprehensive income.

During 2005, MVE entered into alternative clos-
ing 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 arrange-
ments, MVE transferred the economic aspects of the 
remaining private equity funds, consisting of two funds 
and a portion of another fund, to AlpInvest/Lexington 
2005, LLC without a change in ownership of the inter-
ests. The terms of the alternative arrangements do not 
meet the criteria for recording a sale. We are obligated 
to remit to AlpInvest/Lexington 2005, LLC any distribu-
tions MVE receives from these funds, and AlpInvest/
Lexington 2005, LLC is obligated to provide funds to us 
to pay any contribution notice, capital call or other pay-
ment notice or bill for which MVE receives notice with 
respect to such funds. The alternative arrangements 
resulted in a deferred gain of $27.1 million until such 
terms of a sale can be completed (contingent upon 
receipt of general partner approvals of the transfer) 
and in 2005 provided approximately $72 million in net 
proceeds on these funds. DPL recorded an impairment 
loss of $5.6 million in the second quarter of 2005 to 
write down assets transferred pursuant to the alterna-
tive arrangements to estimated fair value. Ownership of 
these funds transfer after the general partners of each 
of the separate funds consent to the transfer. 

On March 31, 2006, MVE completed the sale of the 

remaining portion of one private equity fund, for which 
MVE had previously entered into an alternative closing 
arrangement resulting in the recognition of $13.2 million 
of the deferred gain. On August 31, 2006, MVE com-
pleted the sale of a portion of one of the two remaining 
private equity funds, resulting in recognition of $5.7 
million of the deferred gain. The sale of the residual 
portion of this private equity fund will be completed 
during the first quarter of 2007, resulting in the recogni-
tion of approximately $8.2 million of the deferred gain. 
The transfer of the remaining fund is expected to be 
completed in 2008.

There was no investment income from discontinued 
operations during 2006, however there was $1.3 mil-
lion of legal costs associated with the ongoing litiga-
tion (see Note 11 of Notes to Consolidated Financial 
Statements). Income from discontinued operations 
(pre-tax) for the year ended December 31, 2005 of 
$31.8 million is comprised of $41.3 million of invest-
ment income less $9.5 million of associated manage-
ment fees and other expenses. 

For the year ended December 31, 2006, we rec-

ognized $18.9 million of the deferred gain from the 
sale of the remaining private equity funds described 
above. For the year ended December 31, 2005, we 
recognized a $46.6 million pre-tax gain ($53.1 million 
less $6.5 million of professional fees), recorded a $5.6 
million impairment loss, deferred gains of $27.1 million 
on transferred funds from discontinued operations, and 
provided approximately $868 million in net proceeds, 
including approximately $52 million in net distributions 
from funds held for sale. We will continue to incur minor 
amounts of fees in the near term. 

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

DP&L – Revenues 

For 2006, revenues increased 8% to $1,385.2 million 
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 a $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. 

For 2005, revenues increased 7% to $1,276.9 mil-

lion compared to $1,192.2 million in 2004, reflecting 
an increase of $84.7 million. This increase was primar-
ily the result of increased retail sales volume, higher 
average rates for wholesale and retail revenues, and 
ancillary revenues associated with participation in PJM 
that was partially offset by lower wholesale sales vol-
ume. Retail revenues increased $30.9 million, primarily 
resulting from increased sales volume of $28.9 million 
and $7.6 million in higher average rates, partially offset 
by $5.6 million in lower miscellaneous retail revenues 
reflecting transmission services provided in 2004 that 
are now provided through PJM. Residential custom-
ers comprised the bulk of the increase in sales volume 
reflecting greater weather extremes experienced in 
2005 compared to 2004 as cooling degree days were 
up 39% to 1,075 in 2005 compared to 771 in 2004 
and heating degree days were up 4% to 5,702 in 
2005 compared to 5,500 in 2004. Wholesale revenue 
decreased $2.7 million, primarily related to a $71.6 mil-
lion decline in sales volume that was nearly offset by a 
$68.9 million increase related to higher average market 
rates. For 2005, ancillary revenues from RTOs were 
$74.4 million compared to $17.9 million for 2004, as 
we did not participate in PJM until October 2004. RTO 
ancillary revenues primarily consist of compensation 
for use of our transmission assets, regulation services, 
reactive supply and operating reserves. 

DP&L - Margins, Fuel and Purchased Power 

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 

relatively 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 
increasing 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 million 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 pur-
chase power to source power sales when our generat-
ing facilities were not available due to scheduled main-
tenance and forced outages.

For 2005, gross margin decreased by $6.9 mil-
lion to $811.9 million from $818.8 million in 2004. As a 
percentage of total revenues, gross margin decreased 
by 5.1 percentage points to 63.6% from 68.7%. This 
decline is primarily the result of a $91.6 million increase 
in fuel and purchased power costs, offset by an $84.7 
million increase in revenues (see discussion of revenue 
variance above). Fuel costs increased by $60.9 million 
for 2005 compared to the same period in 2004 primar-
ily resulting from higher average fuel prices as well as 
an increased volume of electric generation. Purchased 
power costs increased by $30.7 million for 2005 com-
pared to the same period in 2004 primarily resulting 
from increased ancillary charges of $36.2 million asso-
ciated with moving power across PJM (we did not par-
ticipate in PJM until October 2004) as well as increases 
related to higher average market prices, partially offset 
by lower purchased power volume.

For 2006, operation and maintenance expense 
increased $33.4 million or 17% compared to 2005 
primarily resulting from a $10.4 million increase in 
power production costs consisting of $4.1 million of 
coal brokering credits received in 2005 that were not 
received in 2006 and increased operating and main-
tenance expenses of $3.1 million which related to cost 
of removal and peaker engine repairs; 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); $3.7 million of lump 
sum bonus and retirement payments for former execu-
tives (not related to our ongoing litigation with the three 
former executives); $2.7 million related to line clear-
ance; $1.9 million increase in long-term incentive costs; 
a $1.9 million increase in reserves for insurance, inju-
ries 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 restricted 
stock units. 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.

Total operation and maintenance expense  $  (26.1)

For 2005, operation and maintenance expense 
decreased $26.1 million or 12% compared to same 
period in 2004 as a result of lower corporate costs that 
were partially offset by increased electric production, 
transmission and distribution expenses. Corporate 
costs declined from the prior year primarily result-
ing from a decrease of $14.8 million in Directors’ and 
Officers’ liability insurance premiums; $10.2 million in 
lower executive and management compensation costs; 
$3.5 million in reduced Sarbanes-Oxley 404 compli-
ance costs and external / internal audit fees; and $1.6 
million in lower PJM administrative fees resulting from 
a PUCO order to defer these costs until they can be 
recovered through rates starting in February 2006. 

These decreases were partially offset by a $4.1 million 
increase in electric production, transmission, and distri-
bution costs, primarily related to generation operations 
costs for lime used for pollution control and electric 
production boiler maintenance costs as well as higher 
costs related to electric distribution operation and 
maintenance. In addition, pension and benefits costs 
rose by $0.6 million reflecting an increase in pension 
costs of $2.0 million that was nearly offset by a $1.4 
million decrease for other post employment benefits, 
principally a 2004 adjustment in disability reserves. 

DP&L – Depreciation and Amortization 

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

Depreciation and amortization increased $2.8 mil-
lion in 2005 as compared to 2004 primarily as a result 
of completed projects in the distribution area (including 
new services, line transformers, poles, station equip-
ment, and overhead and underground conductor) and 
in the production area (mainly due to the SCRs for 
Stuart, Killen and Zimmer) that were put into service in 
the second quarter of 2004.

DP&L – Amortization of Regulatory Assets 

 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 regula-
tory assets reflects $2.6 million for the amortization 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; $1.2 million for the amortization of incremental 
2004/2005 severe storm costs; $0.3 million for the 
amortization of costs incurred to integrate DP&L into 
the PJM system; and $0.2 million for the amortization of 
the Rate Stabilization Surcharge rate case expenses. 
For 2005, amortization of regulatory assets 

increased $1.3 million to $2.0 million compared to the 
same period in 2004 primarily resulting from PJM start-
up costs amortization of $1.1 million and PJM integra-
tion costs amortization of $0.2 million reflecting DP&L’s 
entrance into the PJM market on October 1, 2004.

DP&L – Interest Expense

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 

DPL Inc.

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.

Interest expense decreased $5.4 million or 12% in 
2005 compared to 2004, primarily from $2.6 million of 
lower debt service charges associated with our early 
retirement of ESOP debt; lower amortization of $1.1 mil-
lion associated with reacquired debt; $1.0 million from 
the elimination of the interest penalty on the $470 mil-
lion 5.125% Series First Mortgage Bonds resulting from 
the delayed exchange offer registration of those securi-
ties; and $0.2 million of greater capitalized interest in 
2005 as compared to 2004. 

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.

DP&L – Other Income 

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.

For 2005, other income was $7.7 million greater 
than 2004 primarily reflecting $3.5 million of additional 
gains in 2005 over 2004 from sales of pollution control 
emission allowance. 

DP&L – Income Tax Expense 

For 2006, income tax expense increased $4.1 million 
compared to the same period in 2006 primarily result-
ing from higher income.

For 2005, income tax expense increased $17.3 
million compared to the same period in 2004 resulting 
from higher income, increased accrual for open tax 
years and lower state coal tax credits.

On June 30, 2005, Governor Taft signed House Bill 

66 into law which significantly changed the tax struc-
ture 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 $1.6 mil-

34  DPL Inc.

lion. 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 The Dayton Power and Light Company and 
all of DP&L’s consolidated subsidiaries. All material 
intercompany accounts and transactions have been 
eliminated in consolidation. 

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 a total cost of $400 million. These shares are 
currently held as treasury shares at DPL Inc.

DPL’s Cash Position 

DPL’s cash and cash equivalents totaled $262.2 mil-
lion at December 31, 2006, compared to $595.8 million 
at December 31, 2005, a decrease of $333.6 million. 
In addition, DPL had no short-term investments avail-
able for sale at December 31, 2006 in comparison to 
$125.8 million at December 31, 2005. The decrease in 
cash and cash equivalents and short-term investments 
available for sale was primarily attributed to $357.5 
million in capital expenditures, $400.0 million used for 
the purchase of treasury shares and $112.4 million in 
dividends paid on common stock, partially offset by 
$308.7 million in cash generated from operating activi-
ties and $89.9 million restricted fund draws to fund 
pollution control capital expenditures. At December 
31, 2006, DPL had $10.1 million restricted funds held 
in trust relating to the issuance of the $100 million pol-
lution control bonds. These funds will be used to fund 
the pollution control capital expenditures.

In 2005, DPL began investing in Auction Rate 

Securities (ARS). ARS are variable rate state and 
municipal bonds that trade at par value. Interest rates 
on ARS are reset every seven, twenty-eight or thirty-five 
days through a modified Dutch auction. DPL had the 
option to hold at market, re-bid or sell each ARS on 
the interest reset date. Although ARS are issued and 
rated as long-term bonds, they are priced and traded 
as short-term securities available for resale because of 
the market liquidity provided through the interest rate 
reset mechanism. Each ARS purchased by DPL was 
tax-exempt, AAA rated and insured by a third-party 
insurance company. As of June 30, 2006, all of DPL’s 
ARS were sold. 

DP&L’s Cash Position 

DP&L’s cash and cash equivalents totaled $46.1 
million at December 31, 2006, remained relatively 
unchanged when compared to $46.2 million at 
December 31, 2005. At December 31, 2006, DP&L 
had $10.1 million restricted funds held in trust 
relating to the issuance of the $100 million pollution 
control bonds. These funds will be used to fund the 
pollution control capital expenditures.

Operating Activities

For the years ended December 31, 2006, 2005 and 
2004, cash flows from operations were as follows:

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’s Cash provided by Operating Activities

DPL generated net cash from operating activities of 
$308.7 million, $314.1 million and $132.7 million in 
2006, 2005 and 2004, respectively. The net cash pro-
vided by operating activities in 2006 was primarily the 
result of operating profitability, partially offset by an 
increase in cash used for working capital, specifically 
payments for taxes and inventories. The net cash pro-
vided by operating activities for 2005 was primarily the 
result of operating profitability, partially offset by cash 
used for working capital, specifically accounts payable 
and inventories. The net cash provided by operating 
activities in 2004 was primarily the result of operating 
profitability, partially offset by cash used for the share-
holder litigation settlement and cash used for working 
capital, specifically payments for taxes and inventories. 

DP&L’s Cash provided by Operating Activities

DP&L generated net cash from operating activities 
of $365.7 million, $366.8 million and $381.2 million in 
2006, 2005 and 2004, respectively. The net cash pro-
vided by operating activities for 2006 was primarily the 
result of operating profitability, partially offset by cash 
used for working capital, specifically for accounts pay-
able and inventories. The net cash provided by operat-
ing activities for 2005 was primarily the result of operat-
ing profitability, partially offset by cash used for working 
capital, specifically for accounts payable, inventories 
and the timing of tax payments. The net cash provided 
by operating activities in 2004 was primarily the result 
of operating profitability, and cash provided from work-
ing capital, specifically the timing of tax payments, off-
set by the rising cost of coal inventories.

DPL’s net cash used for investing activities was $229.5 
million in 2006 compared to DPL’s net cash flows 
provided by investing activities of $689.6 million and 
$182.3 million in 2005 and 2004, respectively. Net cash 
flows used for investing activities in 2006 were related 
to capital expenditures and the purchases of short-
term investments 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 
operations 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. Net cash 
flows provided by investing activities for 2004 were 
related to the proceeds from the sale of the private 
equity securities which are classified as discontinued 
operations, proceeds from the sale of property and 
the sale of short-term investments and public securi-
ties unrelated to discontinued operations. These cash 
inflows were 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 
$354.8 million, $178.4 million and $79.9 million in 2006, 
2005 and 2004, respectively. Net cash flows used for 
investing activities for 2006 and 2005 were due to 
capital expenditures. Net cash flows used for investing 
activities for 2004 were due to capital expenditures, off-
set by the proceeds from the sale of property. 

Financing Activities

For the years ended December 31, 2006, 2005 
and 2004, 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 
$412.8 million, $610.0 million and $450.5 million in 
2006, 2005 and 2004, respectively. Net cash flows 
used for financing activities 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 withdrawals from the trust set up 
as a result of issuing the pollution control bonds and 
cash received relating to the exercise of stock options 
of $7.8 million. Net cash flows used for financing activi-
ties for 2005 were primarily the result of cash used to 
retire $462.6 million of long-term debt, pay premiums 
on the early redemption of debt of $54.7 million and 
pay dividends to common stockholders of $115.3 mil-
lion. These uses of cash were partially offset by cash 
received relating to the exercise of stock options of 
$22.7 million. Net cash flows used for financing activi-
ties for 2004 were primarily the result of funds used 
for the retirement of $500 million of the 6.82% Series 
Senior Notes and dividends paid to common stock-
holders, partially offset by the issuance of $175 million 
unsecured 8% Series Senior Notes used to provide 
partial funding for the retirement of the $500 million 
6.82% Series Senior Notes. Annual dividends declared 
increased to $0.96 per share in 2004 from $0.94 per 
share in 2003. 

On February 1, 2006, our Board of Directors 
announced that it had raised the quarterly dividend 
to $0.25 per share payable March 1, 2006 to DPL’s 
common shareholders of record on February 14, 2006. 
This increase resulted in an annualized dividend rate 
of $1.00 per share, or a 4% increase during 2006. 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 common 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 will be paid during 2007.

DP&L’s Cash (used for) Financing Activities

DP&L’s net cash flows used for financing activities 
were $11.0 million, $159.4 million and $301.3 million 
in 2006, 2005 and 2004, respectively. 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 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 $218.9 million of long-term debt and 
pay common stock dividends to DPL of $150.0 mil-
lion. These uses of cash were partially offset by the net 
cash received from the issuance of long-term debt. Net 
cash flows used for financing activities for 2004 were 
for the payment of common and preferred dividends 
and the retirement 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-

36  DPL Inc.

 
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 financ-
ing, 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 from operations 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 sufficient cash flows from operations, 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 $352 million, 
$180 million and $98 million in 2006, 2005 and 2004, 
respectively, and are expected to approximate $310 
million in 2007. 

DP&L’s construction additions were $349 million, 
$178 million and $93 million in 2006, 2005 and 2004, 
respectively, and are expected to approximate $310 
million in 2007. Planned construction additions for 2007 
relate to DP&L’s environmental compliance program, 
power plant equipment, and its transmission and distri-
bution 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 $605 million in capital proj-
ects, approximately 40% of which is to meet chang-
ing environmental standards. Our ability to complete 
capital projects and the reliability of future service will 
be affected by our financial condition, the availability 
of internal funds and the reasonable cost of external 
funds. We expect to finance our construction additions 
in 2007 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 Senior Notes will not be 
redeemable prior to maturity except that DPL has the 
right to redeem the notes for a make-whole payment at 
the adjusted treasury rate plus 0.25%. The 8% Series 

Senior Notes were issued pursuant to its indenture 
dated as of March 1, 2000, and pursuant to author-
ity granted in the Board resolutions dated March 25, 
2004. The notes impose a limitation on the incurrence 
of liens on the capital stock of any of DPL’s significant 
subsidiaries and require DPL and its subsidiaries to 
meet a consolidated coverage ratio of 2 to 1 prior to 
incurring additional indebtedness. The limitation on 
the incurrence of additional indebtedness does not 
apply to (i) indebtedness incurred to refinance exist-
ing indebtedness, (ii) subordinated indebtedness 
and (iii) up to $150 million of additional indebtedness. 
In addition to the events of default specified in the 
indenture, an event of default under the notes includes 
a payment default or acceleration of indebtedness 
under any other indebtedness of DPL or any of its 
subsidiaries which aggregates $25 million or more. 
The purchasers were granted registration rights in con-
nection 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 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 

DPL Inc. 

37

 
 
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. By complet-
ing the exchange, DPL reduced the annual interest 
expense by $1.8 million.

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 Generating 
Stations. These facilities are currently under construc-
tion 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 facili-
ties 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 during 
the first quarter of 2007.

DP&L expects to use the remaining $100 
million of volume cap carryforward prior to the end 
of 2008. DP&L is planning to issue in conjunction 
with the OAQDA this $100 million of tax-exempt 
bonds to finance the remaining solid waste disposal 
facilities at Miami Fort, Killen, Stuart and Conesville 
Generating Stations.

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

$220 million unsecured revolving credit agreement 

replacing its $100 million facility. This new agree-
ment 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 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 facility at December 31, 2006. 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 sublimit. As of December 31, 2006, 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 supports performance assurance 
needs in the ordinary course of business. This agree-
ment was not renewed in 2007. 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 par-
ties to seek additional surety under certain conditions. 
As of December 31, 2006, DP&L had two outstanding 
letters of credit for a total of $2.2 million.

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 con-
nection 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.

There are no inter-company debt collateralizations 
or debt guarantees between DPL and its subsidiaries. 
None of the debt obligations of DPL or DP&L are guar-
anteed or secured by affiliates and no cross-collateral-
ization exists between any subsidiaries.

Coal contracts: 
DP&L has entered into various long-term coal contracts to supply portions of its coal requirements for its 
generating plants. Contract prices are subject to periodic adjustment and have features that limit price escalation 
in any given year. 

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

Other contractual obligations: 
As of December 31, 2006, 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, 2006, 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, 2006, 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.

Guarantees:
DP&L owns a 4.9% equity ownership interest in an electric generation company. As of December 31, 2006, DP&L 
could be responsible for the repayment of 4.9%, or $21.8 million, of a $445 million debt obligation that matures in 2026. 
In two separate transactions in November and December 2006, DPL agreed to be a guarantor of the obligations 

of its wholly-owned subsidiary, DPL Energy, LLC (DPLE) regarding the pending sale 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 has agreed to guarantee the obligations of DPLE over a multiple year period as follows:

Market Risk

As a result of its operating, investing and financing 
activities, we are subject to certain market risks includ-
ing changes in commodity prices for electricity, coal, 
environmental emissions and gas and fluctuations in 
interest rates. Commodity pricing exposure includes 
the impacts of weather, market demand, increased 
competition and other economic conditions. For pur-
poses 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 val-
ues that may or may not occur in the future. 

Commodity Pricing Risk 

Approximately 12.5% of DPL’s and 22% of DP&L’s 
2006 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, 2006, 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, 
2006, a hypothetical increase or decrease of 10% in 
DP&L’s annual wholesale revenues could result 
in approximately a $20 million increase or decrease 
to net income, assuming no increases in fuel and pur-
chased power costs.

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

allowances) and purchased power costs as a percent 
of total operating costs in 2006 and 2005 were 46% 
and 50%, respectively. DP&L’s fuel (including coal, 
gas, oil and emission allowances) and purchased 
power costs as a percent of total operating costs was 
52% in both 2006 and 2005. We have substantially all 
of the total expected coal volume needed to meet our 
retail and firm wholesale sales requirements for 2007 
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 

40  DPL Inc.

 
 
 
 
 
features that limit price escalations in any given year. 
Our consumption of SO2 allowances should decline in 
2007 due to planned emission control upgrades. We 
do not expect to purchase SO2 allowances for 2007. 
The exact consumption of SO2 allowances will depend 
on market prices for power, availability of our genera-
tion 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 2007. 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 weather normalized sales and our co-
owners’ projections, fuel costs are forecasted to be flat 
in 2007 compared to 2006. 

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, 2006, a hypothetical increase or decrease of 10% 
in DPL’s annual fuel and purchased power costs 
could result in approximately a $30 million increase or 
decrease to net income. As of December 31, 2006, a 
hypothetical increase or decrease of 10% in DP&L’s 
annual fuel and purchased power costs could result in 
approximately a $29 million increase or decrease to 
net income.

Interest Rate Risk

As a result of our normal borrowing and leasing activi-
ties, our results are exposed to fluctuations in interest 
rates, which we manage through our regular financ-
ing activities. We maintain both cash on deposit and 
investments in cash equivalents that may be affected 
by adverse interest rate fluctuations. Our long-term 
debt represents publicly and privately held secured 
and unsecured notes and debentures with fixed 
interest rates. At December 31, 2006, we had no short-
term borrowings. 

The carrying value of DPL’s debt was $1,777.7 mil-

lion at December 31, 2006, consisting of DP&L’s first 
mortgage bonds, DP&L’s tax-exempt pollution con-
trol bonds, our unsecured notes and DP&L’s capital 
leases. The fair value of this debt was $1,798.5 million, 
based on current market prices or discounted cash 
flows using current rates for similar issues with similar 
terms and remaining maturities. The principal cash 
repayments and related weighted average interest 

rates by maturity date for long-term, fixed-rate debt at 
December 31, 2006, are as follows:

The carrying value of DP&L’s debt was $786.1 million 
at December 31, 2006, consisting of our first mortgage 
bonds, our tax-exempt pollution control bonds, and our 
capital leases. The fair value of this debt was $785.8 
million, based on current market prices or discounted 
cash flows using current rates for similar issues with 
similar terms and remaining maturities. The principal 
cash repayments and related weighted average inter-
est rates by maturity date for long-term, fixed-rate debt 
at December 31, 2006, are as follows:

Critical Accounting Estimates 

DPL’s and DP&L’s consolidated financial statements 
are prepared in accordance with GAAP. In connection 
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-

DPL Inc. 

41

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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. 
Significant items subject to such judgments include: 
the carrying value of property, plant and equipment; 
unbilled revenues; the valuation of insurance and 
claims costs; valuation allowances for receivables and 
deferred income taxes; the valuation of reserves relat-
ed to current litigation; and assets and liabilities related 
to employee benefits.

Long-Lived Assets:  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 whenever events or circum-
stances indicate that the carrying amount may not be 
recoverable. When required, impairment losses on 
assets to be held and used are recognized based on 
the fair value of the asset. We determine the fair value 
of these assets based upon estimates of future cash 
flows, market value of similar assets, if available or 
independent appraisals, if required. In analyzing the 
fair value and recoverability using future cash flows, 
we make projections based on a number of assump-
tions 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 undiscounted 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 determin-
able, and collectibility is reasonably assured. We 
record electric revenues when delivered to customers. 
Customers are billed throughout the month as electric 
meters are read. We recognize revenues using an 
accrual method for retail and other energy sales that 
have not yet been billed, but where electricity has been 
consumed. This is termed “unbilled revenues” and is a 
widely recognized and accepted practice for utilities. 
Our estimates of unbilled revenues use systems that 
consider various factors to calculate retail customer 
consumption at the end of each month. These esti-
mates are based on the volume of energy delivered, 
historical usage and growth by customer class, and the 
effect of weather variations on usage patterns. Given 
the use of these systems and the fact that customers 
are billed monthly, we believe it is unlikely that materi-
ally different results will occur in future periods when 
these amounts are subsequently billed.

Additionally, DP&L is subject to regulatory orders 

addressing the justness and reasonableness of the 
PJM and Midwest Independent Transmission System 
Operator (MISO) rates and related revenue distribu-
tion protocols. DP&L’s management is required to 
make assumptions, estimates and judgments relating 
to the possibility of refund of these revenues. These 
assumptions, estimates and judgments are based on 
management’s experience and are believed to be rea-
sonable at the time. As a result of these assumptions, 
estimates and judgments, DP&L is deferring a portion 
of these revenues for which management believes is 
subject to refund. The deferred amount recorded was 
$18.7 million and $20.5 million at December 31, 2006 
and December 31, 2005, respectively. The above 
amount collected under the Seams Elimination Charge 
Adjustment (SECA) rates are subject to refund, and 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 mate-
rial adverse effect on our financial condition, results of 
operations or cash flows.

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 

42  DPL Inc.

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 con-
solidated tax liability is allocated to each subsidiary as 
specified in our tax allocation agreement which pro-
vides a consistent, systematic and rational approach. 
See Note 4 of Notes to Consolidated Financial 
Statements.

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) depends on our ability to col-
lect cost-based rates from customers. The recognition 
of regulatory assets requires a continued assessment 
of the recovery of the costs based on actions of the 
regulators. We capitalize incurred costs as deferred 
regulatory assets when there is a probable expectation 
that the costs incurred will be recovered in future rev-
enues as a result of the regulatory process. Regulatory 
liabilities represent current recovery of expected future 
costs. When applicable we apply judgment in the use 
of these principles and these estimates are based 
on expected usage by a customer class over the 
designated recovery period. See Note 3 of Notes to 
Consolidated Financial Statements for further disclo-
sure of regulatory amounts.

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 retirement 
obligations or not, must be removed from a company’s 
accumulated depreciation reserve. We make assump-
tions, estimates and judgments that affect the reported 
amounts of assets, liabilities and expenses 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, wholly-owned 
captive subsidiary (MVIC) provides insurance cover-
age solely to us and to our subsidiaries. Insurance 
and Claims Costs on the Consolidated Balance 
Sheets includes insurance reserves of approximately 
$22 million and $24 million for 2006 and 2005, respec-
tively, 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 uncertainty asso-
ciated with the loss estimates, and actual results may 
differ from the estimates. Modification of these loss 
estimates based on experience and changed circum-
stances is reflected in the period in which the estimate 
is re-evaluated. 

Pension and Postretirement Benefits

We account and disclose pension and postretire-
ment 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 determin-
ing the obligations, annual cost and funding require-
ments of the plans. 

In 2007, we are maintaining our long-term rate of 
return assumptions of 8.50% for pension and 6.75% 
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% 

DPL Inc. 

43

 
for pension and postretirement benefits expense to 
reflect current interest rate conditions. Changes in 
other components used in the determination of pen-
sion and postretirement benefits costs will result in 
approximately the same level of expense in 2007 as in 
2006 ($5.5 million), excluding any special adjustments 
required under SFAS 88. We do not anticipate any spe-
cial adjustments to expense in 2007.

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.

Notes to Consolidated Financial Statements

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 86% 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. Historically, DPL and DP&L have filed 
separate SEC filings. Beginning with this report and in 
the future, DPL Inc. and The Dayton Power and Light 
Company will file combined SEC reports on an interim 
and annual basis.

DPL’s results of operations, financial position and 

cash flows, includes the consolidated results of its 
subsidiaries, including its subsidiary DP&L and all of 
its consolidated subsidiaries. All material intercompany 
accounts and transactions have been eliminated in

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 governmen-
tal customers in a 6,000 square mile area of West 
Central Ohio. Electricity for DP&L’s 24 county service 
area is primarily generated at eight coal-fired power 
plants and is distributed to more than 500,000 retail 
customers. DP&L also purchases retail peak load 
requirements from DPL Energy LLC (DPLE, one of our 
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 

commercial customers in West Central Ohio; MVE, Inc., 
which was primarily responsible for the manage-
ment of our financial asset portfolio; and Miami Valley 
Insurance Company (MVIC), our captive insurance 
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, Judgments and Reclassifications 

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 
liabilities at the date of the financial statements and 
the revenue and expenses of the period reported. 
Different estimates could have a material effect on our 
financial results. Judgments and uncertainties affect-
ing the application of these policies and estimates may 
result in materially different amounts being reported 
under different conditions or circumstances. Significant 
items subject to such estimates and judgments include 
the carrying value of property, plant and equipment; 
unbilled revenues; the valuation of derivative instru-
ments; the valuation of insurance and claims costs; val-
uation allowances for receivables and deferred income 
taxes; regulatory assets and liabilities; reserves record-
ed for income tax exposures; litigation; and assets and 
liabilities related to employee benefits. Actual results 
may differ from those estimates. Certain amounts from 
prior periods have been reclassified to conform to 
the current reporting presentation. In 2005, DPL has 
separately disclosed the earnings from discontinued 
operations, net of income taxes, which in prior periods 
were reported with elements of continued operations. 
In 2005, DPL also separately disclosed the investing 
portions of the cash flows attributable to its discontin-

DPL Inc. 

53

 
ued operations (there was no impact on the operating 
or investing portions of the cash flows), which in 
prior periods were reported on a combined basis as 
a single amount.

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 $68.7 million and 
$63.6 million in 2006 and 2005, respectively. Accounts 
receivable on DP&L’s Consolidated Balance Sheets 
include unbilled revenue of $61.0 million and $57.5 
million in 2006 and 2005, 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 $11.9 million for 2006, 
$6.2 million for 2005, and $8.3 million for 2004.

Allowance for Uncollectible Accounts 

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

Property, Plant and Equipment 

We record our ownership share of our undivided inter-
est in jointly-held plants as an asset in property, plant 
and equipment. Property, plant and equipment are stat-
ed 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 construction proj-
ects. Capitalization of AFUDC ceases at either project 
completion or as of the date specified by regulators. 
AFUDC capitalized related to borrowed funds was $50 
thousand in 2006, and zero in 2005 and 2004. AFUDC 
capitalized for equity funds was $0.4 million in 2006, 
zero in 2005, and $0.5 million in 2004. 

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 $12.9 million in 2006, 
$2.6 million in 2005 and $1.8 million in 2004. 

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 3.3% in 
2006, 3.3% in 2005 and 3.4% in 2004. DPL’s deprecia-
tion expense was $151.8 million in 2006, $147.3 million 
in 2005 and $144.1 million in 2004.

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 
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 retirement 
obligations or not, must be removed from a company’s 
accumulated depreciation reserve. Our legal obliga-
tions associated with the retirement of our long-lived 
assets under SFAS 143 consisted primarily of river 
intake and discharge structures, coal unloading facili-
ties, loading docks, ice breakers and ash disposal 
facilities. Estimating the amount and timing of future 
expenditures of this type requires significant judgment. 
Management routinely updates this estimating as addi-
tional information becomes available.

In March of 2005, the FASB issued FASB 
Interpretation No. 47 (FIN No. 47), “Accounting for 
Conditional Asset Retirement Obligations, an interpreta-
tion of FASB Statement No. 143.” 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.

If FIN No. 47 had been applied as of January 

1, 2003, our asset retirement obligation would have 
increased by $9.4 million and $10.3 million at January 
1, 2004 and December 31, 2004, respectively. Our 
asset retirement obligation was $13.2 million at 
December 31, 2005, which consisted of $5.4 million 
related to the adoption of SFAS 143 in 2003 and $7.8 
million related to the adoption of FIN No. 47 in 2005. 
Our asset retirement obligation was $11.7 million at 
December 31, 2006, which consisted of $5.4 million 
related to the adoption of SFAS 143 in 2003 and $7.8 
million related to the adoption of FIN No. 47 in 2005.

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 business. In 
accordance with SFAS 71, regulatory assets and liabili-
ties 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. See Note 3 of Notes 
to Consolidated Financial Statements.

We evaluate our regulatory assets each period 
and believe recovery of these is probable. We have 
received or requested a return on certain regulatory 
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.

We account for our emission allowances as inventory, 
and record emission allowance inventory at histori-
cal 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. 
Emission allowances are added to inventory when the 
EPA issues us emission allowances at no cost or when 
we purchase emission allowances. Purchased emission 
allowances are recorded in inventory at the purchase 
price, including any related transaction fees. Emission 
allowances are deducted from inventory when used 
in the production of electricity or when we sell excess 
emission allowances. Emission allowances used during 
the production of electricity are charged to fuel costs at 
the weighted average cost for that vintage. The excess/ 
(shortfall) of the sales price over the weighted average 
cost for any emission allowances sold, less related 
fees, is recorded as a gain / (loss) in other income 
(deductions). Emission allowances received as part of 
an exchange of emission allowances are recorded at 
the carrying cost of the emission allowances given up, 
with no gain or loss recorded. 

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 

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 

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 

56  DPL Inc.

 
 
 
 
 
 
 
 
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 pro–
vided unless it is more likely than not that the asset 
will be realized.

are recognized currently in earnings. Financial instru-
ments classified 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.

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 4 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 $22 million and $24 million 
for 2006 and 2005, 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 uncertainty associated with the loss estimates, 
and actual results may differ from the estimates. 
Modification of these loss estimates based on experi-
ence and changed circumstances is reflected in the 
period in which the estimate is re-evaluated. 

Cash and Cash Equivalents

Financial Derivatives 

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 $262.2 million at December 
31, 2006 and $595.8 million at December 31, 2005. 
DP&L’s cash and cash equivalents were $46.1 million 
at December 31, 2006 and $46.2 million at December 
31, 2005. At December 31, 2006, we had $10.1 million 
restricted funds held in trust relating to the issuance 
of the $100 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 instru-
ments of publicly traded entities and classify the 
securities into different categories: held-to-maturity 
and available-for-sale. Available-for-sale securities are 
carried at fair value and unrealized gains and losses 
on those securities, net of deferred income taxes, 
are presented as a separate component of sharehold-
ers’ equity. Other-than-temporary declines in value 

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 
Consolidated Balance Sheets and be measured at fair 
value, and changes in the fair value be recorded in 
earnings, unless they are designated as a cash 
flow hedge of a forecasted transaction or qualify for
the normal purchases and sales exception as dis-
cussed below. 

The FASB issued Statement of Financial 
Accounting Standards No. 149, “Amendment of 
Statement 133 on Derivative Instruments and Hedging 
Activities” (SFAS 149). SFAS 149 amends and clarifies 
financial accounting and reporting for derivative instru-
ments, including those embedded in other contracts, 
and for hedging activities and is effective for contracts 
entered into or modified after June 30, 2003. 

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 

DPL Inc. 

57

 
also hold forward sales contracts that hedge against 
the risk of changes in cash flows associated with 
power sales during periods of projected generation 
facility availability. The FASB concluded that electric 
utilities could apply the normal purchases and sales 
exception for option-type contracts and forward con-
tracts in electricity subject to specific criteria for the 
power buyers and sellers under capacity contracts. 
Accordingly, we apply the normal purchases and sales 
exception as defined in SFAS 133 and account for 
these contracts upon settlement. 

Pension and Postretirement Benefits

We account and disclose pension and postretire-
ment 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. 

Legal, Environmental and Regulatory 
Contingencies

In the normal course of business, we are subject 
to various lawsuits, actions, proceedings, claims 
and other matters asserted under laws and regula-
tions. We believe the amounts provided in our con-
solidated financial statements, as prescribed by 
GAAP, adequately reflect probable and estimable 
contingencies. We record liabilities for probable esti-
mated loss 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. However, there 
can be no assurances that the actual amounts required 
to satisfy alleged liabilities from various legal proceed-
ings, claims, and other matters, and to comply with 
applicable laws and regulations, will not exceed the 
amounts reflected in our consolidated financial state-
ments or will not have a material adverse effect on 
our consolidated results of operations, financial condi-
tion or cash flows. As such, costs, if any, that may be 
incurred in excess of those amounts provided as of 
December 31, 2006, cannot currently be reasonably 
determined. 

Recently Issued Accounting Standards 

Stock-Based Compensation 

In December 2004, the Financial Accounting Standards 
Board (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 pub-
lic entity to measure the cost of employee services 
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-mea-
sured 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 addi-
tion 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. 
Our December 31, 2006 year-to-date pre-tax results of 
operations were increased by approximately $0.7 mil-
lion as a result of the adoption of SFAS 123R. See Note 
9 of Notes to Consolidated Financial Statements.

How Taxes Collected from Customers and 
Remitted to Governmental Authorities Should be 
Presented in the Income Statement

In June 2006, the FASB ratified the consensus of 
Emerging Issues Task Force (EITF) Issue No. 06-3, 
“How Taxes Collected from Customers and Remitted 
to Governmental Authorities Should be Presented 
in the Income Statement (That Is, Gross versus Net 
Presentation)” (EITF 06-3). EITF 06-3 indicates that the 
income statement presentation on either a gross basis 
or a net basis of the taxes within the scope of the issue 
is an accounting policy decision. The consensus is this 
issue should be applied to interim and annual reporting 
periods beginning after December 15, 2006. We are 
in the process of evaluating EITF 06-3 and have not 
determined the impact to our overall results of opera-
tions, financial position or cash flows.

Accounting for Uncertainty in Income Taxes 

In July 2006, the FASB issued Interpretation No. 48, 
“Accounting for Uncertainty in Income Taxes” (FIN 48),

effective for fiscal years beginning after December 15, 
2006. FIN 48 requires a two-step approach to deter-
mine how to recognize tax benefits in the financial 
statements where recognition and measurement of a 
tax benefit must be evaluated separately. A tax benefit 
will be recognized only if it meets a “more-likely-than-
not” recognition threshold. For tax positions that meet 
this threshold, the tax benefit recognized is based on 
the largest amount of tax benefit that is greater than 
50 percent likely of being realized upon ultimate settle-
ment with the taxing authority. We have evaluated the 
requirements of FIN 48 and the adoption of this inter-
pretation and we do not believe at this time that the 
impact will be significant to our overall results of opera-
tions, cash flows or financial position.

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. This Standard 
applies whenever other standards require (or permit) 
assets or liabilities to be measured at fair value. The 
Standard 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, the Standard establishes a fair value hier-
archy that prioritizes the information used to develop 
those standards. The fair value hierarchy gives the 
highest priority to quoted prices in active markets and 
the lowest priority to unobservable data, for example, 
the reporting entity’s own data. Under the Standard, fair 
value measurements would be separately disclosed 
by level within the fair value hierarchy. The Standard 
does not expand the use of fair value in any new cir-
cumstances. We are currently evaluating the impact of 
adopting SFAS 157, and have not yet determined the 
significance of this new rule to our overall results of 
operations, financial position or cash flows.

Employers’ Accounting for Defined Benefit Pension 
and Other Postretirement Plans

In September 2006, the FASB issued Financial 
Accounting Standards No. 158, “Employers’ Accounting 
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: 
a.) recognize the funded status of a benefit plan; 
b.) recognize as a component of other comprehensive 
income, 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; 
c.) measure defined benefit plan assets and obliga-
tions as of the date of the employer’s fiscal year-end 
statement of financial position; d.) disclose in the notes 
to financial statements additional information about 
certain effects on net periodic benefit cost for the next 
fiscal year that arise from delayed recognition of the 
gains or losses, prior service costs or credits, and tran-
sition asset or obligation. 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 end-
ing after December 15, 2008. We have adopted FAS 
158 effective December 31, 2006. See Note 5 of the 
Consolidated Financial Statements.

Considering the Effects of Prior Year 
Misstatements when Quantifying Misstatements 
in Current Year Financial Statements

In September 2006, the Securities and Exchange 
Commission (SEC) issued Staff Accounting Bulletin 
No. 108 (Topic 1N): “Considering the Effects of Prior 
Year Misstatements when Quantifying Misstatements 
in Current Year Financial Statements” (SAB 108). The 
SEC believes that a registrant should quantify a current 
year misstatement using both the iron curtain approach 
and the rollover approach. If the over/understatement 
of current year expense is material to the current year, 
after all of the relevant quantitative and qualitative fac-
tors are considered, the prior year financial statements 
should be corrected. Correcting prior year financial 
statements for immaterial errors would not require 
previously filed reports to be amended. We have evalu-
ated our accounts and determined that SAB 108 does 
not impact our reported results.

Accounting for Planned Major Maintenance Activity

In September 2006, the FASB posted Financial 
Statement of Position AUG AIR -1 – “Accounting for 
Planned Major Maintenance Activity” (FSP AUG AIR-
1). Previous guidance for planned major maintenance, 
such as repairing or replacing a boiler, allowed four 
different methods for accruing for these major repairs. 
These included direct expense, built-in overhaul, defer-
ral and accrue-in-advance. The FASB has decided 
that the accrue-in-advance method is no longer valid 
because it allows a liability to accrue for future charg-
es that may or may not happen. We use the direct 
expense method for major planned maintenance which 
calls for expensing the charges as incurred. Since we 
do not use the accrue-in-advance method, this FSP 
will have no effect on our overall results of operations, 
financial position or cash flows.

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 previously pro-
vided to customers. Since currently existing temporary dif-
ferences 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 unfund-
ed benefit obligation related to the transmission and distri-
bution 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.

Electric Choice systems costs represent costs incurred to 
modify the customer billing system for unbundled rates 
and electric choice bills relative to other generation sup-
pliers and information reports provided to the state admin-
istrator of the low-income electric program. In February 
2005, the PUCO approved a stipulation allowing us to 
recover certain costs incurred for modifications to its bill-
ing system from all customers in its service territory. We 
filed a subsequent case to implement the PUCO’s order to 
begin charging customers for billing costs. On March 1, 
2006, the PUCO issued an order that approved our tariff 
as filed. We began collecting this rider immediately, and 
expect to recover all costs over five years. 

Regional transmission organization costs represent costs 
incurred to join a Regional Transmission Organization 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. On July 12, 2006, the 
PUCO approved our tariff as proposed and we began 
recovering these deferred costs over a two-year period 
beginning August 1, 2006. 

PJM administrative costs contain the administra-
tive fees billed by PJM to us as a member of the PJM 
Interconnection, LLC Regional Transmission Organization 
(RTO). Pursuant to a PUCO order issued on January 25, 
2006, these deferred costs will be recovered over a 3-year 
period from retail ratepayers 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.

Retail settlement system costs represent costs to imple-
ment a retail settlement system that reconciles the amount 
of energy a competitive retail electric service (CRES) 
supplier delivers to its customers and what its customers 
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 reimbursed 
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 con-
nection 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.

Other costs include consumer education advertising 
regarding electric deregulation and costs pertaining to a 
recent 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.

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 estimate of prob-
able refunds for net revenue 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.

5  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 com-
pensation and years of service. We fund pension plan 
benefits as accrued in accordance with the minimum 
funding requirements of the Employee Retirement 
Income Security Act of 1974 (ERISA). In addition, we 
have a Supplemental Executive Retirement Plan (SERP) 
for certain active and retired key executives. Benefits 
under this SERP have been frozen and no additional 
benefits can be earned. We also have unfunded liabili-
ties related to retirement benefits for certain active, 
terminated and retired key executives (not related to 
our ongoing litigation with three former executives). 
These liabilities totaled approximately $0.5 million at 
December 31, 2006.

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 (New SERP) 
which replaces the Company’s Supplemental Executive 
Retirement Plan (SERP) that was terminated as to new 
participations in 2000. The Compensation Committee 
of the Board of Directors will designate the eligible 
employees. Pursuant to the New SERP, we will provide 
a supplemental retirement benefit to participants by 
crediting an account established for each participant 
in accordance with the Plan requirements. We shall 

designate as hypothetical investment funds under the 
New SERP one or more of the investment funds pro-
vided 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 participant does not elect a hypo-
thetical investment fund(s), then we shall 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. 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. Certain disclosures in regard to prior service 
costs, transition costs and net gains/losses are not 
available for 2006 because SFAS 158 was adopted on 
a prospective basis. The incremental effects of adopt-
ing FAS 158 are set out in the following table:

A regulatory asset was recorded for the portion of the 
unfunded obligation related to the transmission and 
distribution areas of our electric business. We have his-
torically recorded these costs on the accrual basis and 
this is how these costs have been historically recov-
ered. This factor, combined with the historical prec-
edents from the PUCO and FERC, make these costs 
probable of future rate recovery.

(a)  The market-related value of assets is equal to the fair value of assets at implementation with subsequent asset gains and losses 
recognized in the market-related value systematically over a three-year period.

(b)  The settlement cost relates to a former officer (not related to our ongoing litigation with three former executives) who has elected to 
receive a lump sum distribution in 2007 from the Supplemental Executive Retirement Plan.

(c)  In 2006 and 2005, special termination benefit costs were recognized as a result of 32 employees who participated in a voluntary 
early retirement program. 16 employees retired at various dates during 2005 and 16 additional employees retired at various dates during 
2006; this program was completed as of April 1, 2006.

(d)  In 2005, a curtailment cost was recognized as a result of a freeze in benefits for the remaining active employee participating in the 
Supplemental Executive Retirement Plan.

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. At December 31, 2006, there were no shares of DPL common stock held 
as 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 welfare 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, 2006 Hewitt Yield Curve. The Hewitt 
Yield Curve represents a portfolio of top-quartile AA-rated bonds used to settle pension obligations and supported

6  Common Shareholder’s Equity

DPL has 250,000,000 authorized common shares, 
of which 113,018,972 are outstanding at December 
31, 2006. DPL had 902,490 authorized but unissued 
shares reserved for its dividend reinvestment plan 
at December 31, 2005. 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 2006 
and 2005.

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 Kohlberg Kravis Roberts & Co. 
(KKR). As part of this recapitalization 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 com-
mon shares at any time during the twelve-year period 
commencing on March 13, 2000. Each warrant is exer-
cisable for one common share, subject to anti-dilution 
adjustments (i.e., stock split, stock dividend). The exer-
cise price of the warrants 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 the DPL and DP&L and no longer had the right to 
designate one person to serve as a non-voting observ-
er of DPL and DP&L. Currently, Dayton Ventures, LLC 
does not have any ownership interest in DPL or DP&L.
DPL has a leveraged Employee Stock Ownership 
Plan (ESOP) to fund matching contributions to DP&L’s 
401(k) retirement savings plan and certain other pay-
ments to full-time employees. Common shareholders’ 
equity is reduced for the cost of 3.8 million unallocated 
shares held by the trust and for 2.7 million shares 
related to other employee plans, of which a total of 6.5 
million shares reduce the number of common shares 
used in the calculation of earnings per share.

Dividends received by the ESOP for unallocated 
shares were used to repay the principal and interest on 
an ESOP loan to DPL. As debt service payments were 
made on the loan, shares are released on a pro-rata 
basis. Dividends on the allocated shares are charged 
to retained earnings. 

ESOP cumulative shares allocated to employees 

and outstanding for the calculation of earnings per 
share were 3.4 million in 2006, 3.2 million in 2005, and 
3.0 million in 2004. Compensation expense associated 
with the ESOP, which is based on the fair value of the 
shares allocated, amounted to $3.7 million in 2006, 
$3.1 million in 2005, and $2.5 million in 2004.

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 par-
ticipate 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 

70  DPL Inc.

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.

(a)  DPL purchased all of its outstanding Series B shares during 2005.

In February 2000, DPL entered into a series of recapi-
talization 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 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 aggre-
gate price of $500 million, with a maturity of 30 years 
(subject to acceleration 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 preferred 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 
million 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 hold-
er. 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. 

The DP&L preferred stock may be redeemed at 
DPL’s option at the per-share prices indicated, plus 
cumulative 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 
distributed subsequent to December 31, 1946 exceeds

the net income of DP&L available for dividends on its Common Stock subsequent to December 31, 1946, plus 
$1.2 million. 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 2006 
earnings reinvested in the business of DP&L to be available for DP&L common stock dividends, payable to DPL.

redeemable prior to maturity except that DPL has the 
right to redeem the notes for a make-whole payment at 
the adjusted treasury rate plus 0.25%. The 8% Series 
Senior Notes were issued pursuant to its indenture 
dated as of March 1, 2000, and pursuant to authority 
granted in Board resolutions dated March 25, 2004. 
The notes impose a limitation on the incurrence of 
liens on the capital stock of any of DPL’s significant 
subsidiaries and require DPL and its subsidiaries to 
meet a consolidated coverage ratio of 2 to 1 prior to 
incurring additional indebtedness. The limitation on 
the incurrence of additional indebtedness does not 
apply to (i) indebtedness incurred to refinance exist-
ing indebtedness, (ii) subordinated indebtedness 
and (iii) up to $150 million of additional indebtedness.

In addition to the events of default specified in the 
indenture, an event of default under the notes includes 
a payment default or acceleration of indebtedness 
under any other indebtedness of DPL or any of its 
subsidiaries which aggregates $25 million or more. 
The purchasers were granted registration rights in con-
nection 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 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. By complet-
ing the exchange, DPL reduced the annual interest 
expense by $1.8 million.

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 Generating 
Stations. These facilities are currently under construc-
tion and the proceeds from the borrowing have been 

placed in escrow with a 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 bond-
holders. DP&L expects to draw down the remaining 
available funds from this borrowing by the end of the 
second quarter 2007.

DP&L expects to use the remaining $100 million 
of volume cap carryforward prior to the end of 2008. 
DP&L is planning to issue in conjunction with the 
OAQDA another $100 million of tax-exempt bonds to 
finance the remaining solid waste disposal facilities at 
Miami Fort, Killen, Stuart and Conesville Generating 
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, 2006. 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 
sublimit. As of December 31, 2006, DP&L had no out-
standing 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 supports performance assurance 
needs in the ordinary course of business. This agree-
ment was not renewed in 2007. 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 par-
ties to seek additional surety under certain conditions. 
As of December 31, 2006, DP&L had two outstanding 
letters of credit for a total of $2.2 million.

There are no inter-company debt collateralizations 
or debt guarantees between DPL, DP&L and their sub-
sidiaries. None of the debt obligations of DPL or DP&L 
are guaranteed or secured by affiliates and no cross-
collateralization exists between any subsidiaries.

9  Stock-Based Compensation

We adopted SFAS 123R on January 1, 2006 using the modified prospective approach for stock options and restrict-
ed stock units (RSUs). As a result of the adoption of SFAS 123R, we recognized $0.7 million less compensation 
expense for the year ended December 31, 2006, as compared to what we would have recognized under SFAS 123. 
In 2000, DPL’s Board of Directors adopted and DPL’s shareholders approved The DPL Inc. Stock Option Plan. 

The plan provides that “no single Participant shall receive Options with respect to more than 2,500,000 shares.” 
Options granted in 2000, 2001 and 2002 were fully vested as of December 31, 2005 and expire ten years from the 
grant date. In 2003, 100,000 options were granted which vest equitably over five years and expire ten years from 
the grant date. In 2004, 200,000 options were granted that vested over nineteen months and expire approximately 
6.5 years from the grant date; 100,000 of these options vested in May 2005 and the remaining 100,000 vested in 
May 2006. Another 20,000 options were granted in 2004 that vested in five months and expire ten years from the 
grant date. In December 2004, 30,000 options were granted that vest equitably over three years and expire ten 
years from the grant date. In 2005, 350,000 options were granted that vested in June 2006 and expire three years 
from the grant date. At December 31, 2006, there were 1,528,500 options available for grant. On April 26, 2006, 
DPL’s shareholders approved The DPL Inc. 2006 Equity and Performance Incentive Plan (EPIP). With the approval 
of 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.

No stock options were granted in 2006. The weighted-average fair value of options granted was $3.80 per 
share in 2005. The fair values of the options were estimated as of the dates of grant using a Black-Scholes option 
pricing model.

There were 355,000 stock options exercised during 2006. The market value of options that were vested 
at December 31, 2006 was approximately $32 million. Shares issued upon share option exercise are issued from 
treasury stock. DPL has sufficient treasury stock to satisfy outstanding options.

As of December 31, 2006, there was $0.1 million of total unrecognized compensation cost related to non-vested 
stock options granted under the Plan. We expect to recognize $0.1 million of this cost in 2007.

In addition, RSUs were granted to certain key employees prior to 2001. There were 1.3 million RSUs outstand-
ing as of December 31, 2006, of which 1.3 million were vested. Substantially all of the vested RSUs are in dispute 
as part of our ongoing litigation with Peter H. Forster, formerly DPL’s Chairman; Caroline E. Muhlenkamp, formerly 
DPL’s Group Vice President and Interim Chief Financial Officer; and Stephen F. Koziar, formerly DPL’s Chief 
Executive Officer and President. The remaining 0.1 million non-vested RSUs will be paid in cash upon vesting and 
will vest as follows: 20,097 in 2007; 14,688 in 2008; 10,205 in 2009; and 5,008 in 2010. Vested RSUs are marked 
to market each quarter and any adjustment to compensation expense is recognized at that time. Non-vested RSUs 
are valued quarterly at fair value using the Black-Scholes model to determine the amount of compensation expense 
to be recognized. Non-vested RSUs do not earn dividends.

The following management assumptions were used in the Black-Scholes model to calculate the fair value 

of the non-vested stock options and RSUs:

Volatility 
Expected life (years) 
Dividend yield rate 
Risk-free interest rate 

 9.5 - 26.1%
 0.6 - 3.6 
 3.7 - 4.7%

At the 2006 Annual Shareholder’s Meeting, DPL’s shareholders approved The DPL Inc. 2006 Equity and 
Performance Incentive Plan. Under the EPIP, the Board adopted a Long-Term Incentive Plan (LTIP) under which 
DPL will award a targeted number of performance shares of common stock to executives. Awards 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 thresh-
old 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 performance condition under FAS 123R. The requisite 
performance period for each tranche of the Performance Shares is:

Tranche 1 
Tranche 2 
Tranche 3 

January 1, 2004 to December 31, 2006

Performance shares do not have an exercise price.

As of December 31, 2006, there was $1.9 million of total unrecognized compensation cost related to 

non-vested performance shares granted under the LTIP. We expect to recognize $1.5 million of this cost in 2007 
and $0.4 million in 2008. A forfeiture rate of 20% was estimated in calculating the compensation expense.

Shares issued upon achievement of the required performance condition will be issued from treasury stock. 

DPL believes it has sufficient treasury stock to satisfy outstanding performance shares.

The following management assumptions were used in the Monte Carlo simulation calculated by an actuarial 
consultant to estimate the fair value of the performance shares:

Volatility 
Expected life (years) 
Dividend yield rate 
Risk-free interest rate 

 17.9% - 20.3%

3.7%
 4.6% - 4.7%

On October 2, 2006, Paul M. Barbas (President and Chief Executive Officer) was granted 19,000 shares of DPL 
Inc. Restricted Stock (Restricted Shares), granted under the 2006 Equity and Performance Incentive Plan. 
The Restricted Shares are to be registered in Mr. Barbas’ name, receive dividends as declared and paid on all 
DPL common stock and will vest in two tranches. A total of 9,000 Restricted Shares shall become non-forfeitable 
on December 31, 2009 if Mr. Barbas remains in the continuous employ of the Company until such date. The 
remaining 10,000 Restricted Shares will become non-forfeitable on December 31, 2011 if Mr. Barbas remains a 
Company employee.

Restricted shares do not have an exercise price.

As of December 31, 2006, there was $0.5 million of total unrecognized compensation cost related to 
non-vested restricted shares granted under the EPIP. We expect to recognize $0.1 million of this cost annually 
over the next five years.

Restricted shares will be issued from treasury stock. DPL believes it has sufficient treasury stock to 

satisfy outstanding restricted shares.

For the quarter ended December 31, 2006, total compensation expense was $1.7 million with an associated 

tax benefit of $0.7 million. Compensation expense for the year ended December 31, 2006 was $5.8 million 
for all share-based compensation (stock options, RSUs, restricted shares and performance shares) and the tax 
benefit associated with these expenses was $2.1 million.

For the year ended December 31, 2006, operating income was $0.7 million higher under SFAS 123R than 
under SFAS 123, while the impact to net income was $0.5 million due to a decrease in the tax benefit of $0.2 
million. There was no impact on basic or diluted earnings per share.

10  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, 2006, we had $359 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 its share of the investment in the facilities is included in the Consolidated Balance Sheets.

Our undivided ownership interest in such facilities at December 31, 2006, is as follows:

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 recog-
nized as the sale of each fund closed. Among other 
closing conditions, each fund required the transaction 
to be approved by the respective general partner of 
each fund. During 2005, MVE and MVIC completed the 
sale of their interests in forty-three and a portion of one 
of those private equity funds resulting in a $46.6 mil-
lion pre-tax gain ($53.1 million less $6.5 million profes-
sional fees) from discontinued operations and provided 
approximately $796 million in net proceeds, including 
approximately $52 million in net distributions from 
funds while held for sale. As part of this pre-tax gain, 
we realized $30 million that was previously recorded as 
an unrealized gain in other comprehensive income.
During 2005, MVE entered into alternative clos-
ing 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 arrange-
ments, 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 
terms of the alternative arrangements do not meet the 
criteria for recording a sale. DPL is obligated to remit 
to AlpInvest/Lexington 2005, LLC any distributions MVE 
receives from these funds, and AlpInvest/Lexington 
2005, LLC is obligated to provide funds to DPL to 
pay any contribution notice, capital call or other pay-
ment notice or bill for which MVE receives notice with 
respect to such funds. The alternative arrangements 
resulted in a 2005 deferred gain of $27.1 million until 
such terms of a sale can be completed (contingent 
upon receipt of general partner approvals of the trans-
fer) and in 2005 provided approximately $72 million in 
net proceeds on these funds. We recorded an impair-
ment loss of $5.6 million in the second quarter of 2005 
to write down assets transferred pursuant to the alter-
native arrangements to estimated fair value. Ownership 
of these funds will transfer after the general partners of 
each of the separate funds consent to the transfer. 

On March 31, 2006, MVE completed the sale of the 

remaining portion of one private equity fund, for which 
MVE had previously entered into an alternative closing 
arrangement resulting in the recognition of $13.2 million 
of the deferred gain. On August 31, 2006, MVE com-
pleted the sale of a portion of one of the two remaining 
private equity funds, resulting in recognition of $5.7 
million of the deferred gain. The sale of the residual 
portion of this private equity fund was completed dur-
ing the first quarter of 2007, resulting in the recognition 
of approximately $8.2 million of the deferred gain. The 
transfer of the one remaining fund is expected to be 
completed in 2008. 

DPL did not have any income from discontinued 
operations in 2006 due to the sale of the portfolio, but 
there were $1.3 million in legal fees directly relating 
to the ongoing litigation related to the asset portfolio. 
DPL’s income from discontinued operations (pre-tax) 
for the year ended December 31, 2005 of $31.8 million 
is comprised of $41.3 million of investment income less 
$9.5 million of associated management fees and other 
expenses. Income from discontinued operations (pre-
tax) for the year ended December 31, 2004 of $154.9 
million is comprised of $178.5 million of investment 
income less $23.6 million of associated management 
fees and other expenses. 

For the year ended December 31, 2006, DPL rec-

ognized $18.9 million of the gain deferred in 2005 from 
the sale of the portfolio. For the year ended December 
31, 2005, DPL recognized a $41.0 million pre-tax gain 
($53.1 million less $6.5 million of professional fees and 
$5.6 million impairment loss), deferred gains of $27.1 
million on transferred funds from discontinued opera-
tions, and provided approximately $868.4 million in net 
proceeds, including approximately $52 million in net 
distributions from funds held for sale. DPL will continue 
to incur minor amounts of fees in the near term. 

In 2006 and 2005, DPL has separately disclosed 

the earnings from discontinued operations, net of 
income taxes, which in prior periods were reported 
with elements of continued operations. Also in 2006 
and 2005, we have separately disclosed the investing 
portions of the cash flows attributable to its discontin-
ued operations (there was no impact on the operating 
or investing portions of the cash flows), which in 
prior periods were reported on a combined basis as 
a single amount.

12  Financial Instruments

The fair value of financial instruments is based on current public market prices, discounted cash flows using cur-
rent rates for similar issues with similar terms and remaining maturities or independent party valuations, which are 
believed to approximate market. The basis on which the cost of a security sold or the amount reclassified out of 
accumulated other comprehensive income was determined by specific identification. The table below presents the 
fair value, unrealized gains and losses, and cost of these instruments at December 31, 2006 and 2005.

In the normal course of business, we enter into various financial instruments, including derivative financial 
instruments. These instruments consist of forward contracts that are used to reduce our exposure to changes in 
energy and commodity prices. These financial instruments are designated at inception as highly effective 
cash-flow hedges and are measured for effectiveness both at inception and on an ongoing basis, with gains or 
losses deferred in Accumulated Other Comprehensive Income until the underlying hedged transaction is realized, 
canceled or otherwise terminated. The forward contracts generally mature within twelve months.

13  Earnings per Share

Basic earnings per share (EPS) are based on the weighted-average number of DPL common shares outstanding 
during the year. Diluted earnings per share 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 by the ESOP.

For the years 2006, 2005, and 2004, respectively, approximately 0.4 million, 0.5 million, and 28.0 million 
warrants and stock options were excluded from the computation of diluted earnings per share because they were 
anti-dilutive. These warrants and stock options could be dilutive in the future.

The following illustrates the reconciliation of the numerators and denominators of the basic and diluted earn-
ings per share computations for income after discontinued operations and cumulative effect of accounting change:

14  Assets Held for Sale

In connection with DPLE’s (significant subsidiary of DPL) decision to sell the Greenville Station and Darby Station 
electric peaking generation facilities, DPL concluded that an impairment charge for the Greenville Station and 
Darby Station assets was required. Greenville Station consists of four natural gas peaking units with a net book 
value of approximately $66 million. Darby Station consists of six natural gas peaking units with a net book value of 
approximately $156 million. DPLE plans to sell the Greenville Station and Darby Station assets for $49 million 
and $102 million, respectively, in two separate transactions. These sales are expected to take place during the 
first half of 2007.

During the fourth quarter of 2006, DPL recorded a $71.0 million impairment charge to record the fair market 

write-down of the assets and other associated costs related to the sale.

These assets are no longer being depreciated. The assets and liabilities held for sale in the Consolidated 

Balance Sheet are as follows:

We enter into various commercial commitments, which may affect the liquidity of our operations. 
At December 31, 2006, 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, 2006, 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.

Guarantees: 
DP&L owns a 4.9% equity ownership interest in an electric generation company. As of December 31, 2006, DP&L could 
be responsible for the repayment of 4.9%, or $21.8 million, of a $445 million debt obligation that matures in 2026. 

In two separate transactions in November and December 2006, DPL agreed to be a guarantor of the obligations of 
its wholly-owned subsidiary, DPL Energy, LLC (DPLE) regarding the pending sale 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 has agreed to guarantee the obligations of DPLE over a multiple year period as follows:

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 ade-
quate in light of the probable and estimable contingen-
cies. (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 Consolidated 
Financial Statements. As such, costs, if any, that may 
be incurred in excess of those amounts provided as of 
December 31, 2006, 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 identi-
fied, 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.” To the extent a proba-
ble 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

Because of uncertainties related to these matters 
accruals are based on the best information available 
at the time. We evaluate the potential liability related to 
probable losses quarterly and may revise its estimates. 
Such revisions in the estimates of the potential liabilities 
could have a material effect on our results of opera-
tions and financial position. 

Legal Matters 

Former Executive Litigation

On August 24, 2004, DPL, and its subsidiaries 
DP&L and MVE, filed a Complaint (and subsequently, 
amended complaints) against Mr. Forster, Ms. 
Muhlenkamp and Mr. Koziar (the Defendants) in the 
Court of Common Pleas of Montgomery County, Ohio 
asserting legal claims against them relating to the 
termination of the Valley Partners Agreements, chal-
lenging the validity of the purported amendments to 
the deferred compensation plans and to the employ-
ment and consulting agreements with the Defendants, 
and the propriety of the distributions from the plans 
to the Defendants, and alleging that the Defendants 
breached their fiduciary duties and breached their 
consulting and employment contracts. DPL, DP&L and 
MVE seek, among other things, damages in excess of 
$25,000, disgorgement of all amounts improperly with-
drawn by the Defendants from the plans and a court 
order declaring that DPL, DP&L and MVE have no fur-
ther obligations under the consulting and employment 
contracts due to those breaches.

The Defendants have filed their answers (and sub-

sequently, amended answers) denying liability and filed 
counterclaims (and subsequently, amended counter-
claims) against DPL, DP&L, MVE, various compensa-

82  DPL Inc.

 
 
 
 
 
tion plans (the Plans), and current and former employ-
ees and current and former members of our Board of 
Directors. These counterclaims, as amended, allege 
generally that DPL, DP&L, MVE, the Plans and the indi-
vidual defendants breached the terms of the employ-
ment and consulting contracts of the Defendants, and 
the terms of the Plans. They further allege theories of 
breach of fiduciary duty, breach of contract, promissory 
estoppel, tortious interference, conversion, replevin 
and violations of ERISA under which they seek distribu-
tion of deferred compensation balances, conversion of 
stock incentive units, exercise of options and payment 
of amounts allegedly owed under the contracts and the 
Plans. Defendants’ counterclaims also demand pay-
ment of attorneys’ fees. 

On March 15, 2005, Mr. Forster and Ms. 

Muhlenkamp filed a lawsuit in New York state court 
against the purchasers of the private equity invest-
ments in the financial asset portfolio and against out-
side counsel to DPL and DP&L concerning purported 
entitlements in connection with the purchase of those 
investments. DPL, DP&L and MVE are not defendants 
in that case; however, the three of us are parties to 
an indemnification agreement with respect to the 
purchaser defendants. On August 18, 2005, the Ohio 
court issued a preliminary injunction against Mr. Forster 
and Ms. Muhlenkamp that precludes them from pursu-
ing certain key issues raised by Mr. Forster and Ms. 
Muhlenkamp in their New York lawsuit that are identical 
to the issues raised in the pending Ohio lawsuit in the 
New York court or any other forum other than the Ohio 
litigation. In addition, the New York court has stayed 
the New York litigation pending the outcome of the 
Ohio litigation. Mr. Forster and Ms. Muhlenkamp have 
appealed the preliminary injunction and the appeal is 
pending at the Ohio Supreme Court.

The trial commencement date for this case is set 

for April 30, 2007.

Cumulatively through December 31, 2006, we 
have accrued for accounting purposes, obligations of 
approximately $56 million to reflect claims regarding 
deferred compensation, estimated MVE incentives and/
or legal fees that Defendants assert are payable per 
contracts. We dispute Defendants’ entitlement to any 
of those sums and, as noted above, are pursuing litiga-
tion against them contesting all such claims.

On or about June 24, 2004, the SEC com-
menced a formal investigation into the issues raised 
by the Memorandum (see Note 17 of the Notes to the 
Consolidated Financial Statements). Although the SEC 
has not taken any significant action in furtherance 
of their investigation during 2006, we stand ready to 
cooperate with their investigation. 

On May 28, 2004, the U.S. Attorney’s Office for 

the Southern District of Ohio, assisted by the Federal 
Bureau of Investigation, notified us that it has initiated 
an inquiry involving the subject matters covered by 
our internal investigation. Although the U.S. Attorney’s 
office and the FBI have not taken any significant action 
in furtherance of their investigation during 2006, we 
stand ready to cooperate with their investigation. 

On June 24, 2004, the Internal Revenue Service 
(IRS) began an audit of tax years 1998 through 2003 
and issued a series of data requests to us including 
issues raised in the Memorandum. The staff of the IRS 
requested that we provide certain documents, includ-
ing but not limited to, matters concerning executive/
director deferred compensation plans, management 
stock incentive plans and MVE financial statements. 
On September 1, 2005, the IRS issued an audit report 
for tax years 1998 through 2003 that showed proposed 
changes to our federal income tax liability for each 
of those years. The proposed changes resulted in a 
total tax deficiency, penalties and interest of approxi-
mately $23.9 million as of December 31, 2005. On 
November 4, 2005, we filed a written protest to one 
of the proposed changes. On April 3, 2006, the IRS 
conceded the proposed changes that we filed a writ-
ten protest to and issued a revised audit report for 
tax years 1998 through 2003. The revised audit report 
resulted in a total tax deficiency, penalties and interest 
of approximately $1.2 million. We had previously made 
a deposit with the IRS of approximately $1.3 million that 
we requested on April 14, 2006 be applied to offset 
the $1.2 million tax deficiency, penalties and interest 
for tax years 1998 through 2003. The Joint Committee 
on Taxation completed its review of the revised audit 
report for tax years 1998 through 2003 and sent us a 
letter dated June 16, 2006 stating that it took no excep-
tion to the revised audit report.

Insurance Recovery Claim

On January 13, 2006, we filed a claim against one 
of our insurers, Associated Electric & Gas Insurance 
Services (AEGIS), under a fiduciary liability policy 
to recoup legal fees associated with our litigation 
against three former executives. An arbitration of this 
matter was held on August 4, 2006. The arbitration 
panel ruled on or about September 12, 2006 that the 
AEGIS policy does not require an advance of defense 
expenses to us. Rather, the arbitration panel stated that 
we are required to file a written undertaking as a condi-
tion precedent to repay expenses finally established 
not to be insured. We have filed a written undertaking 
with AEGIS and will continue to pursue resolution of the 
claim through mediation and arbitration in 2007.

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 2004. 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.

Labor Relations Unasserted Claim

In September 2006, DP&L became aware of an 
unasserted claim under the Fair Labor Standards Act 
concerning the calculation of overtime rates for its 
unionized workforce. By agreement of Local #175 and 
DP&L, we jointly submitted the claim to a neutral third 
party who ruled in favor of DP&L’s position. As a result 
of this decision, Local #175 has decided not to pursue 
any claim against DP&L.

Environmental

Pending before the U.S. Supreme Court is a proceed-
ing, Environmental Defense v. Duke Energy that does 
not involve DP&L as a party but may have a significant 
effect on the outcome of litigation described below 
that involves allegations of violations of the CAA. A 
key issue in that litigation that may be dispositive with 

respect to other pending cases is what test to apply for 
measuring whether modifications to electric generating 
units should trigger application of New Source Review 
(NSR) standards under the CAA. In general terms, the 
dispute is whether to measure pre- and post-modifica-
tion emissions based on the rate of emissions per hour 
of operation or based on total emissions over time. 
The latter test, if applied, could trigger NSR require-
ments for equipment replacements that result in a plant 
running more often because it is more economical or 
dependable, even if the emissions rate per hour of 
operation does not change. A ruling is expected in the 
first or second quarter of 2007. DP&L cannot predict 
the outcome of the Duke Energy case. Moreover, in 
each of the cases identified below, there may be case-
specific facts and allegations that may cause a judge 
to find that the U.S. Supreme Court’s ruling is based on 
different facts and allegations and is therefore not con-
trolling in the case before the judge. 

In September 2004, the Sierra Club filed a law-
suit against DP&L and the other owners of the Stuart 
Generating Station in the United States District Court 
for the Southern District of Ohio for alleged violations 
of the CAA, including issues that may be decided by 
the Supreme Court in the Duke Energy case and other 
issues relating to alleged violations of opacity limita-
tions. 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 are scheduled to 
be filed at various times from May through September, 
2007. Dispositive motions are to be filed in January 
2008. No trial date has been set yet. 

16  Certain Relationships and 
Related Transactions

On March 13, 2000, Dayton Ventures, Inc. and Dayton 
Ventures, LLC, affiliates of Kohlberg Kravis Roberts & 
Co. LLC (KKR), purchased a combination of trust pre-
ferred securities issued by a trust established by DPL, 
DPL voting preferred shares and warrants to purchase 
DPL’s common shares for an aggregate of $550 mil-
lion. The trust preferred securities were redeemed at 
par in 2001 with proceeds of a new issuance of trust 
preferred securities and DPL’s Senior Notes. The 6.6 
million Series B voting preferred shares had voting 
power not exceeding 4.9% of the total outstanding vot-
ing power of our voting securities and were purchased 
by Dayton Ventures, LLC for an aggregate purchase 
price of $68 thousand. The warrants to purchase 
approximately 31.6 million common shares (represent-

84  DPL Inc.

ing approximately 19.9% of the common shares then 
outstanding) have a term of 12 years, an exercise 
price of $21 per share, and were purchased by Dayton 
Ventures, LLC for an aggregate purchase price of $50 
million. In connection with the March 13, 2000 transac-
tion, DPL and KKR also entered into an agreement 
under which we paid KKR an annual management, 
consulting and financial services fee of $1.0 million. 
The agreement also stated that we would provide KKR 
with an opportunity to provide investment banking ser-
vices on such terms as the parties may agree and at 
such time as any such services may be required. We 
also agreed to reimburse KKR and their affiliates for all 
reasonable expenses incurred in connection with the 
services provided under this agreement, including trav-
el expenses and expenses of its counsel. We and KKR 
terminated this agreement on January 12, 2005. During 
December 2004 through January 2005, KKR initiated 
a series of agreements to transfer all of the warrants to 
an unaffiliated third party. This transferee subsequently 
transferred a large portion of the warrants to multiple 
unrelated third parties. In January 2005, as part of 
one of these transfers, KKR sold back to us all of the 
outstanding Series B voting preferred shares at par of 
$0.01 per share for $66 thousand. 

Under the Securityholders and Registration Rights 

Agreement among DPL Inc., DPL Capital Trust I, 
Dayton Ventures, LLC and Dayton Ventures, Inc., KKR 
had the right to designate one person for election to, 
and one person to attend as a non-voting observer at 
all meetings of, the DPL and DP&L Boards of Directors 
for as long as Dayton Ventures, LLC and its affiliates 
continue to beneficially own at least 12.64 million of 
our common shares, including shares issuable upon 
exercise of warrants. Scott M. Stuart, a director dur-
ing fiscal 2003, and George R. Roberts, a non-voting 
observer, were the KKR designees in 2003 pursuant 
to this agreement. Mr. Stuart resigned from the Board 
and Mr. Roberts ceased to be a non-voting observer of 
the Board as of April 2004. As a result of the transfer of 
warrants from KKR to an unaffiliated third party during 
December 2004 through January 2005, KKR no longer 
owned any warrants or common stock. Accordingly, 
KKR no longer had the right to appoint one member 
and one observer to both DPL and DP&L Boards of 
Directors and the Securityholders and Registration 
Rights Agreement was amended to delete these, and 
other, rights. 

In 1996, DPL entered into a consulting contract 
pursuant to which Peter H. Forster agreed to (i) serve, 
in a non-employee capacity, as Chairman of the Board 
of Directors of DPL, DP&L and MVE, and as Chairman 
of the Executive Committee of our Board of Directors 

and (ii) provide advisory and strategic planning con-
sulting services. That contract became the subject of 
litigation after Mr. Forster resigned on May 16, 2004. 
(See Note 15 of Notes to Consolidated Financial 
Statements.)

In June 2001, DPL’s subsidiaries, MVE, of which 
Mr. Forster was Chairman, Miami Valley Development 
Company (MVDC) and Miami Valley Insurance 
Company (MVIC), each entered into a management 
services agreement (the MSAs) with Valley Partners, 
Inc. (Valley) for the provision of ongoing oversight and 
management of each subsidiary’s financial asset hold-
ings following a change of control of DPL or sale of the 
financial assets portfolio to an unaffiliated third party. 
Valley was a Florida corporation the sole stockholders, 
directors and officers of which were Mr. Forster and 
Ms. Muhlenkamp.

In October 2001, we entered into an Administrative 
Services Agreement (the ASA) with Valley and the indi-
vidual trustees of certain master trusts which hold the 
assets of various executive and director compensation 
plans. The ASA engaged Valley to provide adminis-
trative and recordkeeping functions on behalf of the 
master trusts upon a change of control of DPL, as well 
as the provision of investment advice, in exchange for 
an administration fee in addition to the annual manage-
ment fee payable to Valley.

In October 2001, DPL and DP&L also entered 

into a Trustee Fee Agreement (the TFA) with Richard 
Chernesky, Richard Broock and Frederick Caspar, 
attorneys at Chernesky, Heyman & Kress P.L.L. Upon a 
change of control of DPL or DP&L, Messrs. Chernesky, 
Broock and Caspar would become the sole trustees 
of the master trusts for an annual fee of $500,000 and 
would succeed to all of the duties of our Compensation 
Committee under the compensation plans funded 
through the master trusts.

The MSAs, ASA and TFA (Valley Partners 

Agreements) were terminated by an agreement execut-
ed in January 2004, but effective as of December 15, 
2003. The financial assets were not sold or transferred 
prior to such termination and therefore the agreements 
never became effective and no compensation was ever 
paid under them. Copies of the Valley Partners Agree–
ments were filed as exhibits to our 2003 Form 10-K.

On April 26, 2004, DPL entered into a New Trustee 

Fee Agreement (New TFA) with Messrs. Chernesky, 
Broock and Caspar that would have become effec-
tive upon a change of control of DPL or DP&L. If the 
New TFA became effective, it provided that Messrs. 
Chernesky, Broock and Caspar would serve as the sole 
trustees of the master trusts in exchange for an annual 
fee of $250,000 during the New TFA’s term. A copy of 

DPL Inc. 

85

 
the New TFA was filed as an exhibit to our 2003 Form 
10-K. On October 14, 2004, at the request of DPL and 
DP&L, Messrs. Chernesky, Broock and Caspar submit-
ted their resignations to us and DP&L.

On February 2 and 3, 2004, Mr. Koziar sent let-
ters to Mr. Forster and Ms. Muhlenkamp purporting to 
amend their consulting and employment agreements 
to provide change of control protections regarding 
their MVE payments. In addition, on February 2, 2004, 
Mr. Koziar sent Mr. Forster a letter purporting to amend 
his consulting agreement to provide additional terms 
and to increase his compensation. However, none 
of those purported amendments had been approved 
by our Compensation Committee. Mr. Forster and 
Ms. Muhlenkamp resigned and Mr. Koziar retired on 
May 16, 2004. 

We have initiated legal proceedings asserting 
breach of fiduciary duty and breach of contract by 
Messrs. Forster and Koziar and Ms. Muhlenkamp, and 
challenging the propriety and/or validity of certain con-
tract terminations, purported amendments and agree-
ments. (See Note 15 of Notes to Consolidated Financial 
Statements.)

17  Other Matters

Audit Committee Investigation and 
Related Matters

On March 10, 2004, DPL’s and DP&L’s Corporate 
Controller, sent a memorandum (the Memorandum) 
to the Chairman of the Audit Committee of our Board 
of Directors (the Audit Committee). The Memorandum 
expressed the Corporate Controller’s “concerns, 
perspectives and viewpoints” regarding financial 
reporting and governance issues within the Company. 

On March 15, 2004, our Audit Committee 

retained the law firm of Taft, Stettinius & Hollister LLP 
(TS&H) to represent the Audit Committee in an 
independent review of each of the matters raised 
by the Memorandum. TS&H subsequently retained an 
accounting firm as a forensic accountant to assist 
in this review. On April 27, 2004, TS&H submitted a 
written report of its findings to the members of the 
Audit Committee (the Report). A copy of the Report 
was filed as an exhibit to our 2003 Form 10-K. While 
TS&H stated that it did not uncover and no person had 
indicated to it any uncorrected material inaccuracies 
in our books and records, it did, however, recommend 
further follow-up by the Audit Committee and improve-

ments relating to disclosures, communication, access 
to information, internal controls and the culture of 
the Company in certain areas. Based upon informa-
tion received after issuing the Report, TS&H revised 
its analysis and prepared a supplement to the Report, 
dated May 25, 2004 (the Supplement). A copy of 
the Supplement was filed as an exhibit to our 2003 
Form 10-K.

Our Audit Committee considered the Report and 
Supplement at a meeting held on May 16, 2004. After 
its review and consideration, the Audit Committee 
recommended that the full Board of Directors accept 
the Report and the Supplement. At a meeting held on 
May 16, 2004, our Board of Directors accepted the 
Report and Supplement, including the findings and 
recommendations set forth therein. Mr. Forster and Ms. 
Muhlenkamp resigned and Mr. Koziar retired on May 
16, 2004, and subsequently DPL and DP&L have been 
involved in litigation with them (see Note 15 of Notes 
to Consolidated Financial Statements). In addition, in 
2004 corrective action was taken with regard to internal 
controls, process issues and tone at the top as identi-
fied in the Report.

Governmental and Regulatory Inquiries 

On May 20, 2004, the staff of the SEC notified DPL 
that it was conducting an inquiry covering our exempt 
status under the Public Utility Holding Company Act 
of 1935 (the ’35 Act). The staff of the SEC requested 
DPL provide certain documents and information on a 
voluntary basis. On October 8, 2004, DPL received 
a notice from the SEC that a question existed as to 
whether such exemption from the Public Utility Holding 
Company Act was detrimental to the public interest or 
the interests of investors or consumers. On November 
5, 2004, DPL filed a good faith application seeking an 
order of exemption from the SEC. In light of the repeal 
of the ’35 Act, effective February 8, 2006, and based 
upon the information previously provided to the staff of 
the SEC, this inquiry is moot. 

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, 2006 and 2005, and the related consolidated statement of results of operations, shareholders’ 
equity, and cash flows for each of the years in the three-year period ended December 31, 2006. 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, 2006. These consolidated financial statements and the financial statement schedule are the 
responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated 
financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight 
Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance 
about whether the financial statements are free of material misstatement. An audit includes examining, on a test 
basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes 
assessing the accounting principles used and significant estimates made by management, as well as evaluating 
the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, 

the financial position of the Company as of December 31, 2006 and 2005, and the consolidated results of their 
operations and their cash flows for each of the years in the three-year period ended December 31, 2006, in 
conformity with United States generally accepted accounting principles. Also, in our opinion, the related financial 
statement schedules when considered in relation to the basic consolidated financial statements taken as a whole, 
present fairly in all materials respects, the information set forth therein.

As discussed in Note 1 to the consolidated financial statements, effective January 1, 2006, the Company 
adopted FASB Statement of Financial Accounting Standard No. 123 (Revised), Share-Based Payment. Also dis-
cussed in Note 1 to the consolidated financial statements effective December 31, 2006 the Company adopted 
FASB Statement of Financial Accounting Standard No. 158, Employers’ Accounting for Defined Benefit Pension and 
Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106 and 132(R).

We also have audited, in accordance with the standards of the Public Company Accounting Oversight 

Board (United States), the effectiveness of the Company’s internal controls over financial reporting as of December 
31, 2006, based on criteria established in Internal Control - Integrated Framework issued by the Committee 
of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated February 22, 2007 
expressed an unqualified opinion on management’s assessment of, and the effective operation of, internal control 
over financial reporting.

Report of Independent Registered Public Accounting Firm on Internal Controls

The Board of Directors
DPL Inc.:

We have audited management’s assessment, included in the Management’s Report on Internal Control Over 
Financial Reporting appearing under Item 9A, that DPL Inc. and subsidiaries (the Company) maintained effective 
internal control over financial reporting as of December 31, 2006, 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 maintaining effective internal control over financial reporting 
and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to 
express an opinion on management’s assessment and an opinion on the effectiveness of the Company’s internal 
control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board 
(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about 
whether effective internal control over financial reporting was maintained in all material respects. Our audit included 
obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, 
testing and evaluating the design and operating effectiveness of internal control, and performing such other proce-
dures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis 
for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance 

regarding the reliability of financial reporting and the preparation of financial statements for external purposes 
in accordance with generally accepted accounting principles. A company’s internal control over financial reporting 
includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, 
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable 
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance 
with generally accepted accounting principles, and that receipts and expenditures of the company are being 
made only in accordance with authorizations of management and directors of the company; and (3) provide 
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the 
company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect 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, management’s assessment that the Company maintained effective internal control over 

financial reporting as of December 31, 2006, is fairly stated, in all material respects, based on criteria established 
in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (COSO). Also, in our opinion, the Company maintained, in all material respects, effective internal 
controls over financial reporting as of December 31, 2006, based on criteria established in Internal Control - 
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). 
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 

(United States), the consolidated balance sheets of the Company as of December 31, 2006 and 2005, 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, 2006, and our report dated February 22, 2007, expressed an 
unqualified opinion on those consolidated financial statements.

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) and subsidiaries as of December 31, 2006 and 2005, 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, 2006. In connection with our audits of the consolidated financial statements, we have audited the consoli-
dated financial statement schedule, “Schedule II - Valuation and Qualifying Accounts” for each of the years in the 
three-year period ended December 31, 2006. These consolidated financial statements and the financial statement 
schedules are the responsibility of DP&L’s management. Our responsibility is to express an opinion on these 
consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight 
Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance 
about whether the financial statements are free of material misstatement. An audit includes examining, on a test 
basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assess-
ing the accounting principles used and significant estimates made by management, as well as evaluating the 
overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, 
the financial position of DP&L as of December 31, 2006 and 2005, and the consolidated results of their operations 
and their cash flows for each of the years in the three-year period ended December 31, 2006, in conformity 
with United States generally accepted accounting principles. Also, in our opinion, the related financial statement 
schedules 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, 2006 the Company 
adopted FASB Statement of Financial Accounting Standard No. 123 (Revised), Share-Based Payment. Also dis-
cussed in Note 1 to the consolidated financial statements effective December 31, 2006 the Company adopted 
FASB Statement of Financial Accounting Standard No. 158, Employers’ Accounting for Defined Benefit Pension and 
Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106 and 132(R).

We also have audited, in accordance with the standards of the Public Company Accounting Oversight 

Board (United States), the effectiveness of the Company’s internal controls over financial reporting as of December 
31, 2006, based on criteria established in Internal Control - Integrated Framework issued by the Committee 
of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated February 22, 2007 
expressed an unqualified opinion on management’s assessment of, and the effective operation of, internal control 
over financial reporting.

Report of Independent Registered Public Accounting Firm on Internal Controls

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

We have audited management’s assessment, included in the Management’s Report on Internal Control Over 
Financial Reporting appearing under Item 9A, that The Dayton Power and Light Company (DP&L) and subsidiaries 
maintained effective internal control over financial reporting as of December 31, 2006, based on criteria established 
in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (COSO). DP&L’s management is responsible for maintaining effective internal control over financial 
reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is 
to express an opinion on management’s assessment and an opinion on the effectiveness of DP&L’s internal control 
over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board 
(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about 
whether effective internal control over financial reporting was maintained in all material respects. Our audit included 
obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, 
testing and evaluating the design and operating effectiveness of internal control, and performing such other proce-
dures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis 
for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance 
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in 
accordance with generally accepted accounting principles. A company’s internal control over financial reporting 
includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, 
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable 
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance 
with generally accepted accounting principles, and that receipts and expenditures of the company are being 
made only in accordance with authorizations of management and directors of the company; and (3) provide 
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of 
the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect 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, management’s assessment that DP&L maintained effective internal control over financial report-

ing as of December 31, 2006, is fairly stated, in all material respects, based on criteria established in Internal 
Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission 
(COSO). Also, in our opinion, DP&L maintained, in all material respects, effective internal controls over financial 
reporting as of December 31, 2006, based on criteria established in Internal Control - Integrated Framework issued 
by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

We also have audited, in accordance with the standards of the Public Company Accounting Oversight 
Board (United States), the consolidated balance sheets of DP&L as of December 31, 2006 and 2005, 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, 2006, and our report dated February 22, 2007, expressed an 
unqualified opinion on those consolidated financial statements.

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 information required to be 
disclosed by us in the reports that we submit under the 
Exchange Act is accumulated and communicated to 
our management, including our principal executive and 
principal financial officers, or persons performing simi-
lar functions, as appropriate, to allow timely decisions 
regarding required disclosure.

The following report is our report on internal control 
over financial reporting as of December 31, 2006.

Management’s Report on Internal Control 
Over Financial Reporting

We are responsible for establishing and maintaining 
adequate internal control over financial reporting, 
as such term is defined in Exchange Act Rule 
13a-15(f). Under the supervision and with the partici-
pation 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, 2006. 

Our assessment of the effectiveness of our internal 

control over financial reporting as of December 31, 
2006, has been audited by KPMG LLP, the indepen-
dent registered public accounting firm that audited 
the financial statements contained herein, as stated in 
their report which is included herein.
